From the perspective of the working mode of the paper tube machine, in the relay control circuit, when the power is turned on, all the relays in the circuit are in a restricted state, that is, the pull-in relays are closed at the same time, and the relays that should not Certain conditions cannot be combined. This kind of working method is called parallel working method. The PLC's user program is executed in a cyclic order. Therefore, each soft relay is in a cyclic scan. The sequence of each relay subject to the same condition is determined by the program scan sequence. This working method is called serial. Way of working. 2. From the control method of the paper tube machine, the control logic of the electrical control system uses hardware wiring, and the control logic of the relay mechanical contacts is connected in series or parallel. The PLC uses computer technology, and its control logic is stored in the memory as a program. To change the control logic, you only need to change the program, so it is easy to change or add system functions.
1. Wear personal protective equipment properly. What you should wear must be worn, and what you should not wear must not be worn. For example, a female worker is required to wear a protective cap during paper tube machining. If she does not wear it, she may twist her hair. At the same time, it is required not to wear gloves. If it is worn, the rotating part of the paper tube machine may twist the gloves in and hurt hands.
2. The paper tube machinery and equipment must also undergo safety inspection in accordance with regulations during operation. The special paper tube machine is to see if the fastened object is loose due to vibration in order to re-tighten.
3. Before the operation, the paper tube machinery and equipment must be inspected for safety, and the truck must be run empty. After confirming that it is normal, it can be put into operation.
4. It is strictly forbidden to operate the equipment with faults. Do not make use of it to prevent accidents.
5. When the paper tube machinery is in operation, it is strictly forbidden to adjust by hand; nor shall it be used to measure parts by hand, or to lubricate and clean up debris. If necessary, the machinery and equipment should be shut down first.
6. The knives, jigs, and processed parts used in paper tube machinery and equipment must be installed firmly and must not be loose.
7. The mechanical safety device must be used correctly in accordance with regulations, and it must never be removed and not used.
8. When the paper tube mechanical equipment is running, the operator must not leave the work post to prevent unattended disposal when problems occur.
9. After the work is completed, the switch should be turned off, the tools and workpieces should be withdrawn from the working position, and the work site should be cleaned up. The parts, jigs, etc. should be neatly arranged to clean the paper tube machinery and equipment.

        The operating principle of the paper tube machine under different control systems is introduced:
        1. From the working mode of the paper tube machine, in the relay control circuit, when the power is turned on, all the relays in the circuit are in a restricted state, that is, the pull-in relays are closed at the same time. The relay is limited by certain conditions and cannot be pulled in. This kind of working mode is called parallel working mode. The PLC user program is executed cyclically in a certain order. Each soft relay is in a cyclic scanning scan. The sequence of each relay subject to the same condition is determined by the program scanning sequence. This working method is called serial work. the way. 2. From the control method of the paper tube machine, the control logic of the electrical control system uses hardware wiring, and the control logic of the relay mechanical contacts is connected in series or parallel. PLC uses computer technology, and its control logic is stored in memory in the form of a program. To change the control logic, only the program needs to be changed, so it is easy to change or add system functions. Paper tube machine adopts CNC computer numerical control system, SMS synchronous mobile cutting and cutting device, equipped with imported servo drive, can greatly reduce the resistance of the cutter to the paper tube during the cutting operation, and make the gap of the paper tube uniform. The blade of the paper tube machine adopts imported single circular knife cutting design, and the fully CNC-driven cutter (non-cylinder driven) achieves accurate cutting. Ultra quiet design of transmission part of paper tube machine (national patent), improve work efficiency!
        Application of paper tube machine in packaging industry
        At present, the beverage industry's degree of attention to aseptic cold filling production lines has reached a new level, and the use of aseptic cold filling equipment by beverage production enterprises has become an inevitable trend.
        The investment cost of aseptic cold filling production line has always been the concern of the beverage industry. With the continuous reduction of equipment costs by equipment suppliers, the investment cost of paper tube machines for aseptic cold filling production lines has been reduced to 1.5 of the hot filling line. ～ 1.6 times, and the supplier of domestic aseptic cold filling production line of paper tube machine has also matured continuously. Filling equipment Paper tube machine is the most core equipment on the production line. Whether the filling equipment can be quickly converted has attracted widespread attention from enterprises. Because when producing different products or different bottle types, the filling equipment will lose valuable filling time and reduce production efficiency due to the conversion of paper tube equipment.

        Before cutting the paper tube machine, adjust the cutter and clamp the work. The parking baffle must be fixed, and work can only be carried out after a test run of clamping, loosening, forward and backward. When the machine tool is rotating, no part of the human body should touch the transmission parts.
        Paper tube machine must pay attention to when operating:
        Cuffs must be worn during operation, and gloves are strictly forbidden to work. Spindle speed must be changed after stopping. Gears must be fully engaged during shifting. When the machine is found to be abnormal, stop the machine immediately for inspection. When the long material pipe is put into the material rack and the lead wire is loosened, measures should be taken to prevent the pipe from rolling, impacting and crushing people. Check that the dust removal device is intact before cutting. When using a grinding wheel pipe cutter, check the grinding wheel sheet for defects, cracks, moisture, and whether the power cord is reliable. When changing tools, measuring workpieces, lubricating, and cleaning pipe heads, it must be stopped.

1. The machine is powered on, and the lead screw and guide rail of the machine are filled with lubricating oil.
2. According to the thickness of the paper tube required by the paper tube machine, load the corresponding amount of paper on the paper holder.
3 Check whether there is debris in the glue pool of the paper tube machine, so as not to block the pipeline and the injection pump. (If the glue needs to be heated, warm the glue pool in advance. Before heating, check whether the heated water is added to the proper amount.)
4. Check whether the silicone rod of the paper tube machine is damaged. You can change the silicone rod up and down according to the paper passing position.
5. Wear the belt according to the winding of the belt and check whether the cutting blade is damaged. If damaged, replace it in time. Check the cutting tube for burrs and smooth them in time.
6. Adjust the cutting table height and feed according to the diameter of the production paper tube, and adjust the position of the length measuring photoelectric switch according to the length of the paper tube.
7. The paper enters the glue coating part and the glue scraping part through the paper feeding part of the glue tank. Pay attention to the position where the paper passes before and after. Manually apply glue before paper scraping to increase lubrication, so as not to pull the paper over the Ambassador paper.
8. The paper enters the main machine through the cloth rack of the main machine. Before that, the bottom paper is wound on the mold shaft. At this time, turn the first set of handwheels to tighten the belt. When the paper passes through the second set of belts, turn the second set of belts to tighten the handwheel to tighten the belts.
9. After all the paper is loaded, check whether the length and thickness of the paper are qualified before making adjustments.
10. During the production process of the paper tube machine, someone must always pay attention to the adhesive force of the glue, check whether the paper tube is suitable, and whether the paper is broken.
11. Regular maintenance and precautions of paper tube machine:
① Check the oil level of the reducer oil of the main engine every day for any lack of oil. Replace every 6 months.
② The oil-water separator should be checked daily for lack of oil and replaced every 7 days.
③ The glue injection pump should be cleaned to see if any debris enters the pump body.
④ The glue scraper should be inspected daily and replaced if there is damage.
⑤The cutting blade should be checked every day, and if damaged, it should be replaced in time.
⑥ The belt should be cleaned once a day, if it is damaged, it should be replaced in time, otherwise the paper surface will be damaged.
If the paper tube cut is not flat, it can be completed by adjusting the left and right adjustment bolts on the cutting table.

        The correct installation of the paper tube machine is very important. Only the correct installation can ensure that the subsequent equipment can run normally. So do you know how to install paper tube machinery? Let's take a look at the specific content together!
        First of all, it is necessary to make relevant installation preparations, mainly including three parts: 1. technical preparations; 2. preparations for the use of paper tube machinery; 3. preparations for the supply of paper and paper tube glue. In other words, before the equipment is running, it is necessary to prepare various tools and materials required for technical aspects, and transport the installed paper tube machine mechanical equipment to the site in time to unpack, inspect, disassemble, clean, and lubricate.
        Next, the paper tube machinery needs to be checked and confirmed accordingly to keep the normal operation in the later period. And make appropriate adjustments and lubrication care. It should be noted that, before installation, it is necessary to check and clean the components accordingly. This includes removing the applied anti-rust agent and internal iron scraps, rust and dust accumulated during transportation and storage, and cleaning before cleaning. It is generally required to be lubricated after cleaning.
        After the assembly of the paper tube machine is completed, a trial operation of the paper tube machine must be performed first. At this time, you should pay close attention to the running status of the equipment. If there is any abnormality, stop the machine in time for inspection. Remember, the added lubricant must be tested before it can be used. The lubricating oil must be filtered before adding the equipment, and the added oil should reach the specified oil level.
