Operation control system 　 touch screen man-machine interface, regardless of correction, fine-tuning can be easily solved.
Alarms and operating status are displayed on the screen instantly for easy control.　Unwinding system 　The material loading and unloading adopts pneumatic shaft clamping and hydraulic lifting structure.
The unwinding adopts automatic constant tension control, EPC automatic correction, and variable frequency motor traction, which greatly reduces the paper roll registration adjustment time.　Perfect after-sales service, eliminating customers' worries. Accurately track printed materials, greatly reduce machine adjustment and setting time, and improve production efficiency.

The automatic hand square bottom paper bag machine is a single-sheet paper, roll-type head card and paper rope as raw materials, which can complete the manufacture of handles, stick the handles, fold the mouth, form a tube, form an organ, seal the bottom, and compact in one time. Or stick the head card, fold the mouth, form a tube, form an organ, perforate corns, seal the bottom, and compact and form two perfect processes. One machine and two uses, excellent value for money. Especially suitable for outsourcing handbag production of clothing, footwear, sports brand or luxury brand.
Fully automated production is truly realized, directly out of bags and packaged to customers.
The flat-sheet four-corner square-bottom paper bag machine is to make the printed single-sheet paper through the machine to complete the bag at one time. It has paper feeding from the single sheet, vertical pressure line, top glue, tube forming, horizontal pressure line, open bottom, and bottom Gluing, folding square bottom, paper bag pressing and forming finished products, etc. are fully automatic production functions. The HD-180 paper bag machine has obvious advantages in producing thinner paper and high speed. It has strong high-speed production stability and extremely convenient debugging. It is an ideal equipment for large printing plants and paper bag manufacturers.
It is suitable for the production of environmentally friendly paper bags, food paper bags (chestnut belt, bread belt), gift belts and cosmetic paper bags with paper as raw materials.
Automatic food paper bag machine This machine is a new generation of high-speed machine developed by our factory based on the original food paper bag machine and through the efforts of all our employees. It is an ideal equipment for producing food paper bags, bread paper bags and various non-staple food paper bags.
The crystallization of all paper bag machine products at home and abroad. This machine automatically hydraulically feeds primary colors or printed webs from the machine, glues the top, makes the tube, cuts, bottoms indentation, bottoms glue, bag bottom forming, and produces the finished bag. The computer central control system, the process is controlled by The man-machine interface touch screen display, PLC control, the length of the paper bag is controlled by the servo motor, and the finished paper bag of various specifications can be produced. It can produce 220 bags at the fastest per minute, which greatly reduces labor costs. It is an ideal partner in your business.

Automatic deviation correction and automatic constant tension control; with material change warning, paper break and shutdown device. The handle machine is an independent unit, and the servo drive is synchronized with the host. The length of the handle rope can be adjusted accordingly according to the specifications of the paper bag. The placement position is cut off and the placement position is glued using servo drive, which is controlled synchronously with the cutting of the host; the placement position is glued using a roller transfer method. Pneumatic pressing wheel is used to press the handle to make the handle fit tightly to the paper bag.

Paper bag machines often have some problems, we need to understand the reasons for these problems. If there is an error in the length of the cut bag, we need to lock the rubber roller, and then check whether the film is clamped in the rubber roller. Secondly, we need to observe whether the feeding speed is too high. If it is too high, we need to reduce the feeding speed in time. There are errors in the length of the cut bag.
①First, "lock the shaft" of the feeding rubber roller, and pull the film hard to see if it is not clamped in the feeding rubber roller. If it is not clamped, properly adjust the pressure of the feeding roller until the film cannot be pulled.
②Whether the "feeding speed" is too high, reduce the "feeding speed" appropriately.
③Whether the clamping device of the rear bread red cloth clamps too tightly, adjust appropriately. If it cannot be clamped too tightly, it is better to pull the film gently.
④Try to loosen or tighten the aluminum gantry tube.
2. The length of the cut out bag is the same, but it is not satisfied with the set value
①Press "2" to enter the password in the computer standby mode? Enter the actual length for correction
3. The bag is not sealed tightly or one side is not strong
①Whether the temperature is set properly: LDPE material is above 280°, BOPP material is above 320°
②Adjust the position of the heat sealing knife
③Check whether the conveyor belt is pulling the material too early. The upper conveyor belt should be closed just after the heat-sealing knife leaves the silicone roller 20mm-25mm high.
④Check the transmission bearing of the upper conveyor belt
