Description

Technical Field

[0001] This utility model relates to the field of bag making and processing, specifically to a high-efficiency hot-cutting bag making machine. Background Technology

[0002] Hot cutting is an important technology in the plastics processing industry. It uses high-temperature cutting blades to quickly cut plastic films, offering significant advantages in bag manufacturing. Compared to traditional mechanical cutting methods, hot cutting not only effectively improves production efficiency but also ensures smooth, even cuts, avoiding burrs.

[0003] During continuous operation, high-temperature cutters are prone to accumulating molten plastic residue on their surface. This can be due to factors such as the small amount of molten splatter produced when cutting plastic materials at high temperatures, or the instantaneous high temperature at the contact surface between the cutter and the material causing some plastic components to carbonize and adhere.

[0004] As impurities accumulate during production, they affect the heat transfer efficiency of the cutter, leading to a decline in cut quality and, in severe cases, even material adhesion failure. Regular shutdowns for manual cleaning require disassembling the cutter assembly each time, which is time-consuming on average. Utility Model Content

[0005] The technical problems to be solved by this invention are the cleaning of the cutting blade and the cooling of the product.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: This utility model is a high-efficiency hot-cutting bag making machine, including a bag making machine, a hot cutter on the bag making machine, cleaners symmetrically installed on the hot cutter, a cooler on one side of the bag making machine, and two sets of cleaners. Each cleaner includes a mounting base, a fixed box, a mover, and a scrubber. The mounting base is installed on the side of the bracket of the hot cutter, the fixed box passes through the mounting base, and the fixed box has a moving opening. The mover is located on the fixed box and slides through the moving opening. The scrubber is fixedly installed on the mover and contacts and cleans the cutter blade of the hot cutter.

[0007] Furthermore, the mover includes a motor, a screw, a nut, a connecting rod, and a limiting structure. The motor is mounted on the inner wall of one side of the fixed box. One end of the screw is fixed to the output shaft of the motor, and the other end rotates on the inner wall of the other side of the fixed box. The nut is threaded onto the screw. The connecting rod is fixed to the nut. Multiple sets of connecting rods are provided. The limiting structure is fixed inside the fixed box.

[0008] Furthermore, the motor is a reversible motor.

[0009] Furthermore, the limiting structure includes a limiting rod, a limiting tube, and a connecting seat. The limiting rod is fixedly mounted on the fixing box, and there are two sets of limiting rods and two sets of limiting tubes. The limiting tubes are slidably sleeved on one set of limiting rods, and the connecting seat is fixedly mounted between the two sets of limiting tubes.

[0010] Furthermore, the scrubbing device includes a sliding block, a sliding plate, a push rod, a push plate, and a cleaning cotton. The sliding block is fixedly mounted on the connecting seat and slides through the moving opening. The sliding plate is fixedly mounted on the sliding block. The push rod is fixedly mounted on the sliding plate. The push plate is fixedly mounted on the output rod of the push rod. The cleaning cotton is fixedly mounted on the push plate.

[0011] Furthermore, the cooler includes a connecting frame, a mounting frame, and a fan. There are two sets of connecting frames, which are installed on the side wall of the bag making machine. The mounting frame is fixedly installed on the connecting frame, and the fan is installed on the mounting frame. There are multiple sets of fans.

[0012] Furthermore, multiple sets of cold water pipes are provided between the connecting frames, and the cold water pipes are connected to an external chiller.

[0013] The beneficial effects of this utility model by adopting the above structure are as follows:

[0014] 1. The cutter can be cleaned using the cleaners on both sides. Cleaning is only required once after a certain number of uses, without having to completely stop the machine and disassemble it, which can improve work efficiency again. In addition, the cleaning cotton is retractable and will not affect the up and down movement of the cutter.

[0015] 2. Use a cooling device to cool the cut bags when needed, especially the cut area, so that they do not need to be left to stand, thus improving work efficiency. Attached Figure Description

The cleaner 3 includes a mounting base 5, a fixing box 6, a mover 7, and a scrubber 8. The mounting base 5 is installed on the side of the bracket of the hot cutter 2, the fixing box 6 passes through the mounting base 5, and the fixing box 6 has a moving opening. The mover 7 is set on the fixing box 6 and slides through the moving opening. The scrubber 8 is fixedly set on the mover 7 and contacts and cleans the cutter of the hot cutter 2.

[0023] As per the instruction manual Figure 4 As shown, the mover 7 includes a motor 9, a screw 10, a nut 11, a connecting rod 12, and a limiting structure 13. The motor 9 is mounted on the inner wall of one side of the fixed box 6. One end of the screw 10 is fixed to the output shaft of the motor 9, and the other end rotates on the inner wall of the other side of the fixed box 6. The nut 11 is threaded onto the screw 10. The connecting rod 12 is fixed to the nut 11, and multiple sets of connecting rods 12 are provided. The limiting structure 13 is fixed inside the fixed box 6. The motor 9 is a forward and reverse rotating motor, and the motor controller is mounted on the housing of the bag making machine 1 or the housing of the fixed box 6.

[0024] As per the instruction manual Figure 4 As shown, the limiting structure 13 includes a limiting rod 14, a limiting tube 15, and a connecting seat 16. The limiting rod 14 is fixedly mounted on the fixing box 6. There are two sets of limiting rods 14 and two sets of limiting tubes 15. The limiting tubes 15 are slidably sleeved on one set of limiting rods 14 respectively. The connecting seat 16 is fixedly mounted between the two sets of limiting tubes 15.

[0025] As per the instruction manual Figure 4 As shown, the scrubber 8 includes a sliding block 17, a sliding plate 18, a push rod 19, a push plate 20, and a cleaning cotton 21. The sliding block 17 is fixedly mounted on the connecting seat 16 and slides through the moving opening. The sliding plate 18 is fixedly mounted on the sliding block 17.
