From the point of view 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 simultaneously closed, and the relays that should not be closed are affected. Certain conditions can not be combined, and this kind of thing method is called parallel thing method.
        In order to ensure the long-term good operation of paper tube machinery, staff must adhere to the corresponding operating rules. First of all, when starting the equipment, it should be started at no load, and after a trial run to confirm that there are no abnormalities, production can be officially started. As the saying goes, everyone is responsible for safe production. Only by ensuring the normal operation of the equipment can the safety of production operations be ensured.
        In daily work, be sure to arrange someone to be responsible for managing the paper tube machinery, and other personnel must not operate the equipment at will. During work, you need to observe the operating status of the equipment to ensure that the equipment is used in the correct manner.
        Only by constantly optimizing and upgrading the performance of paper tube machinery, or strengthening its functions, etc., so as to bring greater help to users. In this way, not only can the influence be increased in the market, but also richer economic benefits can be obtained. Especially in today's era, whether to grasp this point has become a very critical issue. For the entire industry, the speed of upgrading machinery and production lines is of great significance.

Paper cutting tube machine is widely used in printing, packaging, leather, household, hardware and other industries. It is especially suitable for plastic or paper tubes used in labels, non-woven fabrics, films, tapes, etc. The surface of the cut paper tube is smooth and flat, no flanging, no lint, and can also cut paper tubes of different inner diameters, and can be adjusted according to your desired length within the effective range.
Before operating the machine, please read the instruction manual carefully and pay special attention to the following safety precautions
1. The cuffs of work clothes should be fastened.
2. It is strictly forbidden to put your head and hands into the rotating part of the paper cutting machine.
3. Do not wear gloves during operation.
4. The surrounding environment of the paper cutting machine should be clean, tidy, and the light is suitable. No other sundries should be placed nearby to avoid inconvenience to the operator.
5. The product equipment, especially the rotary part of the paper cutting machine, cannot place everything such as workpieces, tools, etc.
6. The power must be cut off before maintenance.

        Paper tube machine, as its name implies, is the machine and equipment for producing paper tube. The paper tube produced is used in various industries, chemical fiber industry tube, film industry tube, printing industry tube, paper industry tube, leather industry tube, food. Packaging tube, construction industry tube, exhibition industry tube, etc. There are also many types of paper tube machines. The most common paper tube machines are spiral paper tube machines and roll paper tube machines.
         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.

        Preparation for paper tube machine production, such as paper tube machine product design and test research, process equipment design and manufacturing, various production materials and production organization, etc. Preparation work for paper tube machine part blanks, such as casting , Forging and stamping, etc .; various processes of paper tube machine parts, such as machining, welding, heat treatment and surface treatment.
        Paper tube machine can be used for flocking after diluted with water. Sticky-mounted paper tubes, cartons, and cartons dry quickly and have high hardness. The finished product does not degumme, run away, do not collapse, do not foam, do not soften, absorb moisture, and do not yellow. Applications: Can be used for high-strength paper tubes, paper drums, corrugated paper production lines, single-sided corrugated paperboard bonding, color bonding of high-speed fully automatic, semi-automatic surface bonding machines, honeycomb paperboard splicing, tissue composite, high-end cardboard boxes Carton adhesive molding.

        With a fast-changing society, the pace and development of the society are getting faster and faster. Many industries have fierce competition every day, and the packaging industry is no exception. With the gradual accumulation of time, China's packaging industry has begun to integrate with the international market. The technology development of packaging is fast, and it is continuously improving in the direction of economy, efficiency and multi-function. In the packaging industry, the paper packaging industry is developing faster and faster. In order to use the development of the paper industry, the requirements for paper tube machines are becoming higher and higher. frequency.
        In manufacturing, specialized production has become a trend. International packaging machinery manufacturers attach great importance to the universal capabilities of packaging machinery and the entire packaging system. Some common standard parts are no longer produced by paper tube machinery equipment factories, and some special parts are produced by highly specialized manufacturers. Packaging machinery companies are, in a sense, assembly plants. In terms of packaging functions of paper tube machinery and equipment, industrial and agricultural products should be refined and diversified, and paper tube machinery and equipment products should be developed in the direction of product multi-function and single high-speed polarization. In terms of technical performance, other fields Advanced technology is applied to paper tube machinery and equipment.
        The replacement method is to replace local parts or key components and key technologies, so as to achieve the purpose of replacing a unit, so that the production capacity, performance, efficiency, model and assembly method of the original packaging machinery and equipment or production line are obtained. Update. In this way, most parts and unit parts are reused, which not only improves the value of equipment, but also saves raw materials and a large amount of labor, and reduces costs. Under the continuous updating and survival, the paper tube machine has gradually realized the continuous progress of the industry, and the corresponding technology has been updated and advanced, forming a virtuous cycle development model.
