[0018] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0019] Combine Figure 1 The utility model discloses a hot and cold integrated knife holder for a single-pack paper drawing machine, comprising a main bracket 1, which is a frame-type frame. A motor assembly 2 is provided on the upper surface of the main bracket 1, and a movable hole 11 is provided on the main bracket 1 on one side of the motor assembly 2. The main bracket 1 is also provided with symmetrically distributed linear bearings 12, and a metal partition 13 is provided on the inner wall of the lower side of the main bracket 1. A cutter assembly is provided inside the main bracket 1, and the cutter assembly is connected to the motor assembly 2. The motor assembly 2 drives the cutter assembly to move up and down, and works on the metal partition 13 to cut the packaging material. End plates 14 are symmetrically provided at both ends of the lower side of the main bracket 1, and the two ends of the end plate 14 are movably connected to a film rod 15. A rubber bottom plate 16 is provided on the side of the film rod 15 away from the main bracket 1, and a bottom plate seat 17 is provided below the rubber bottom plate 16.

[0020] The motor assembly 2 comprises a motor support 21, a servo motor 22, a speed reducer 23, an eccentric wheel 24, fish eye adjusting bearings 25 and positive and negative adjusting bolts 26. The lower end of the motor support 21 is connected to the upper surface of the general support 1 by bolts. The upper end of the motor support 21 is provided with the servo motor 22 and the speed reducer 23. The output end of the servo motor 22 is connected to the speed reducer 23. The output end of the speed reducer 23 is connected to the eccentric wheel 24. The servo motor 22 controls the rotation of the eccentric wheel 24 through the speed reducer 23. One side of the eccentric wheel 24 is connected to the fish eye adjusting bearings 25. Two fish eye adjusting bearings 25 are provided and connected to the upper and lower ends of the positive and negative adjusting bolts 26. The combination of the fish eye adjusting bearings 25 and the positive and negative adjusting bolts 26 is a very effective adjusting tool, which can realize accurate position and angle adjustment in multiple degrees of freedom. The self-aligning function of the fish eye adjusting bearings 25 is combined with the bidirectional thread design of the positive and negative adjusting bolts 26, which improves the adjustment accuracy and simplifies the installation process. The positive and negative adjusting bolts 26 penetrate the movable hole 11. The middle of the positive and negative adjusting bolts 26 is provided with a control nut. Rotating the control nut can adjust the overall length of the positive and negative adjusting bolts 26.

[0021] The cutter assembly comprises a spring fixing plate 3, a heating plate 4 and a film pressing frame 5. The fish eye adjusting bearings 25 at the lower end of the positive and negative adjusting bolts 26 are movably connected to the upper surface of the spring fixing plate 3. Bearing guide columns 31 are symmetrically arranged on the upper surface of the spring fixing plate 3. The bearing guide columns 31 are movably connected to the linear bearings 12. The eccentric wheel 24 rotates and pulls the spring fixing plate 3 up and down through the fish eye adjusting bearings 25 and the positive and negative adjusting bolts 26. The bearing guide columns 31 move up and down in the linear bearings 12 to guide the movement of the spring fixing plate 3. Cold cutters 32 are arranged at the edges of the spring fixing plate 3. The cold cutters 32 move up and down with the spring fixing plate 3 to cut the packaging material. Knife pressure relief springs 41 are symmetrically arranged at the two ends of the upper surface of the heating plate 4. Film pressing springs 51 are symmetrically arranged at the two ends of the film pressing frame 5. The upper ends of the knife pressure relief springs 41 and the film pressing springs 51 are connected to the spring fixing plate 3. Guiding rods are arranged in the knife pressure relief springs 41 and the film pressing springs 51. The guiding rods penetrate the spring fixing plate 3. The knife pressure relief springs 41 and the film pressing springs 51 drive the heating plate 4 and the film pressing frame 5 to move up and down with the spring fixing plate 3. The film pressing frame 5 is arranged below the working area of the heating plate 4. Hot cutters 42 are arranged on the lower surface of the heating plate 4. The heating plate 4 heats the hot cutters 42 to realize hot cutting. The film pressing frame 5 works outside the outer ring of the heating plate 4.

[0022] Working process: the packaging material is guided into the working area of the tool holder through the film guide rod 15, and the film is ensured to be flat and wrinkle-free. By rotating the control nut, the overall length of the forward and reverse adjusting bolt 26 can be adjusted, so as to accurately control the initial position of the cutter assembly. The self-aligning function of the fish eye adjusting bearing 25 allows the cutter assembly to automatically adjust the angle within a certain range, ensuring the accuracy of cutting and heat sealing. When the system receives the cutting and heat sealing instruction, the servo motor 22 starts, and the eccentric wheel 24 is driven to rotate through the speed reducer 23. The rotation of the eccentric wheel 24 pulls or pushes the spring fixing plate 3 through the fish eye adjusting bearing 25 and the forward and reverse adjusting bolt 26, so that the cutter assembly moves up and down. The bearing guide column 31 on the spring fixing plate 3 slides up and down in the linear bearing 12, ensuring the vertical movement of the cutter assembly and avoiding lateral deviation. The up and down movement of the spring fixing plate 3 is transmitted to the heating plate 4 and the film pressing frame 5 through the cutter decompression spring 41 and the film pressing spring 51. The hot cutter 42 on the heating plate 4 contacts the packaging material when moving downward, and realizes heat sealing and cutting through heating. The film pressing frame 5 works outside the heating plate 4 to press the packaging material tightly on the metal partition plate 13, ensuring the stability of cutting and heat sealing. The cold cutter 32 cold cuts the packaging material to separate from the whole packaging material. When the eccentric wheel 24 rotates to another position, the fish eye adjusting bearing 25 pushes the spring fixing plate 3 upward through the forward and reverse adjusting bolt 26, and the cutter assembly gradually resets. The cutter decompression spring 41 and the film pressing spring 51 help the heating plate 4 and the film pressing frame 5 reset quickly, preparing for the next cutting and heat sealing operation.
