[0028] Among them, the winding device includes a fixed roller 2 mounted on the left end of the upper side of the processing table 1, two sliders 4 slidably connected to the right end of the upper side of the processing table 1, a vertical frame 12 fixedly connected to the upper side of the slider 4, a driving motor 8 fixedly installed on the side of one of the vertical frames 12 and a winding roller 7 fixedly connected to the output end of the driving motor 8, one of the first clamping blocks 15 is fixedly connected to the lower side of the connecting plate 14, the other first clamping block 15 is slidably connected to the connecting plate 14, a second slide groove 18 is provided inside the lower side of the connecting plate 14, the first clamping block 15 and the hot cutting tool 17 are both provided with through holes suitable for inserting the second clamping block 23, a groove 20 is provided on the opposite side of the two first clamping blocks 15, and the spring 27 is internally mounted on the lower end of the outer side of the slide rod 25.

[0029] Example 2:

[0030] See also Figure 1 On the basis of the first embodiment, it includes a first slide groove 5 provided on the right end of the upper side of the processing table 1 and adapted to the bottom of the slider 4, a ruler 6 is fixedly connected to one side of the support frame 3, a latch 9 is inserted into the right side of the vertical frame 12, and a plurality of horizontally arranged positioning holes 10 are provided on one end of the upper side of the processing table 1 near the latch 9, and an arrow 11 used in conjunction with the ruler 6 is fixedly connected to one side of one of the vertical frames 12.

[0031] By adopting the above technical solution, the distance between the winding roller 7 and the support frame 3 is adjusted when the slider 4 slides in the first slide groove 5, and the arrow 11 is used to move on one side of the ruler 6 to know the moving distance between the support frame 3 and the winding roller 7, and then the pin 9 is inserted into the corresponding positioning hole 10 to limit the winding roller 7 and prevent it from moving.

[0032] The working principle of the above embodiment is:

[0033] After the plastic bag is fixed on the outside of the fixed roller 2, one end of the plastic bag passes through the lower side of the support frame 3 and is sleeved on the outer surface of the winding roller 7, the position of the winding roller 7 and the support frame 3 is adjusted according to the spacing of the hot-cut plastic bags, and the lower side of the slider 4 slides in the first slide groove 5 to match the arrow 11 and moves on the side of the ruler 6 to more clearly know the distance between the hot-cutting device and the winding roller 7. After adjusting to the required position, align the right side of the stand 12 with the corresponding positioning hole 10 up and down, insert the latch 9 to fix the winding roller 7 to prevent movement, take out the hot-cutting tool 17, align the limit block 19 at one end of the upper side with the groove 20 opened by the first clamping block 15 on the left, and insert and fix the other end to the length of the hot-cutting tool 17, slide the first clamping block 15 in the second slide groove 18 to adjust the spacing position and clamp the hot-cutting tool 17, take out the fixing plate 21 and use the second clamping block 23 from one end of the first clamping block 15 to simultaneously penetrate the first clamping block 15 and the hot-cutting tool 17, and move the block When 26 contacts the surface of the first block 15 and the hot cutting tool 17, the sliding rod 25 is squeezed and the spring 27 compresses itself to change the position of the moving block 26. After moving away, the spring 27 is used to rebound and push the moving block 26 out from the other end of the first block 15 to achieve the purpose of limiting and assembling. The driving motor 8 is started to rewind the plastic bag on the outside of the winding roller 7. When the rewinding length is the same as the length of the arrow 11 and the scale of the ruler 6, the driving motor 8 is turned off and the electric telescopic rod 13 is started at the same time to push the hot cutting tool 17 downward to perform hot cutting on the plastic bag. When disassembling the hot cutting tool 17, the electromagnetic block control switch 22 is pressed to start the electromagnetic plate 24 and the electromagnetic block 28 to generate magnetic force, pushing the moving block 26 to move into the second block 23 without limiting the hot cutting tool 17. Then, the first block 15 on the right is pulled to separate from the hot cutting tool 17, and then the hot cutting tool 17 on the left is pulled to separate from the first block 15 to complete the disassembly.
