[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Heat cutting machines are commonly used in the packaging industry, effectively cutting plastic bags into the required sizes and shapes. In actual processing, different products may require packaging bags of different sizes, necessitating cutting materials to different lengths. However, existing heat cutting equipment has a relatively complex mechanical structure, and adjusting the cutting length usually requires multiple steps or operations, increasing the difficulty of adjustment and making it inconvenient for operators. To address the shortcomings of the aforementioned equipment in adjusting the cutting length, please refer to [link to relevant documentation]. Figures 1-5This utility model provides a heat-cutting device that is easy to adjust the cutting length. It can quickly adjust the distance between the positioning plate and the heat-cutting blade, thereby adjusting the cutting length of the material. It has the advantages of simple operation and convenient use. After the adjustment is completed, the end of the material can be tightened and fixed to prevent the material from shifting, thereby ensuring the cutting accuracy of the device. The device is based on a processing table 1. A hot cutting mechanism 2 and a positioning mechanism 3 are respectively installed at the top two ends of the processing table 1. The hot cutting mechanism 2 is used to cut the material, and the positioning mechanism 3 is used to determine the position of the material end and fix the material end. The positioning mechanism 3 includes a bracket 31, which is slidably installed on the top of the processing table 1. A drive mechanism 4 is provided on the outside of the processing table 1 to drive the bracket 31 to slide. The distance between the hot cutting mechanism 2 and the positioning mechanism 3 can be adjusted by the drive mechanism 4, thereby adjusting the cutting length of the material. Indicator arrows 33 are fixedly connected to both sides of the bracket 31, and scale lines 5 are provided on both sides of the processing table 1. The distance between the hot cutting mechanism 2 and the positioning mechanism 3 can be determined by the indicator arrows 33 and the scale lines 5. A positioning plate 32 and a clamping member 34 are provided inside the bracket 31. The positioning plate 32 is used to position the end of the material. The end of the material is pulled to fit tightly against the positioning plate 32, and the material is fixed by the clamping member 34, thereby driving the hot cutting mechanism 2 to cut the material.

[0030] Because materials may shift, stretch, or wrinkle during cutting, resulting in inaccurate sealing positions and inaccurate cutting lengths, this problem is addressed by installing two horizontal plates 341, which are fixedly installed on both sides of the inner wall of bracket 31. A steering rod 342 is rotatably mounted on the top of each horizontal plate 341, with a counterweight roller 343 rotatably mounted at one end and a pressing block 344 at the other end. An extrusion block 345 is slidably mounted on the horizontal plate 341, with a slope of 25°-40°. A bidirectional screw 347 is rotatably mounted between the inner walls of both sides of bracket 31. The threads on the outer surface of the bidirectional screw 347 are two segments with opposite directions of rotation. Both ends of the bidirectional screw 347 are threadedly connected to a hanger 346, which is connected to the side of each of the two extrusion blocks 345. The bidirectional screw 347 is fixedly connected to a bracket 31. One end of the bidirectional screw 347 passes through the bracket 31 and is fixedly connected to a handle 348. Rotating the handle 348 facilitates the rotation of the bidirectional screw 347. The rotation of the bidirectional screw 347 pushes two extrusion blocks 345 towards the counterweight roller 343 via the suspension rod 346. The extrusion blocks 345 can squeeze the counterweight roller 343, causing the steering rod 342 to rotate. The pressing block 344 rotates and presses down to compress the material, thereby fixing the material and ensuring its stability during the hot cutting process, thus ensuring the cutting accuracy. It should be noted that the counterweight roller 343 has a certain weight. After cutting, similarly, rotating the handle 348 causes the extrusion blocks 345 to slide away from the counterweight roller 343. The steering rod 342 can reverse due to the gravity of the counterweight roller 343, which can release the compressive effect on the material and facilitate the removal of the cut material.

[0031] To achieve automatic adjustment of the cutting distance of the equipment, a servo motor 41 is provided. The servo motor 41 is fixedly installed at one end of the processing table 1, and the output end of the servo motor 41 is fixedly connected to a lead screw 42. The lead screw 42 is rotatably installed on the side of the processing table 1. One end of the bracket 31 is threaded to the outer surface of the lead screw 42. When adjusting the cutting length of the equipment, it is only necessary to drive the servo motor 41 to drive the lead screw 42 to rotate. The rotation of the lead screw 42 will drive the bracket 31 to slide. The operation is simple and convenient, and no manual adjustment is required, reducing the difficulty of adjustment.

[0032] Reference Figure 1 , Figure 2 and Figure 5 As shown, bracket 21 is used as the base. Bracket 21 is fixedly installed on the top of processing table 1. A hydraulic rod 22 is installed on the top of bracket 21. A tool holder 23 is installed at the output end of the hydraulic rod 22. A hot cutting knife 24 is fixedly installed inside the tool holder 23. Driving the hydraulic rod 22 can drive the hot cutting knife 24 to press down, thereby cutting the material.

[0033] In order to optimize the cutting effect of the equipment, a cutting groove 6 is provided on the processing table 1. The cutting groove 6 is V-shaped and is adapted to the hot cutting blade 24. The cutting groove 6 can make the hot cutting blade 24 completely penetrate the material and cut the material thoroughly.

[0034] To further ensure the smoothness of the cut, refer to Figure 5 As shown, supports 25 are fixedly connected to both sides of the blade holder 23. A rotating shaft 26 is fixedly connected inside the support 25. Connecting rods 27 are rotatably sleeved at both ends of the rotating shaft 26. A pressure roller 28 is rotatably installed between the two connecting rods 27. A torsion spring 29 is installed between the side of the connecting rod 27 and the inner wall of the support 25. The torsion spring 29 is sleeved on the outside of the rotating shaft 26. When the hydraulic rod 22 drives the blade holder 23 to press down, the pressure roller 28 squeezes the material downward. As the pressure roller 28 presses down, the connecting rod 27 can rotate on the rotating shaft 26, causing the torsion spring 29 to deform. The pressure roller 28 squeezes the material and rotates through the torsion of the torsion spring 29, which can flatten the material to both sides along the center line of the hot cutting blade 24, thereby ensuring the flatness of the material cut.

[0035] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
