Description

Technical Field

[0001] The utility model relates to a die cutting machine, in particular to a waste edge recycling mechanism of a heat pack machine. Background Art

[0002] A heat pack machine is a special equipment for producing heat packs. During the production process, the base material of the heat pack is cut, and the waste edges after cutting need to be recycled through a waste edge recycling mechanism. The Chinese patent document (Publication No.: CN109383039 A; Publication Date: February 26, 2019) discloses a heat pack machine, and its waste material recycling mechanism includes a mounting frame, on which a material table, a soft round roller, an upper cutting knife, a lower fixed knife and a discharge hopper are provided. The soft round roller is rotatably arranged on the material table for waste material traction. The upper cutting knife and the lower fixed knife are cooperatively arranged at the front end of the waste material traction for waste material cutting. The discharge hopper is arranged below the lower fixed knife to receive the cut waste material.

[0003] The defects of the above structure are as follows: The soft round roller and the material table are used in cooperation for waste material traction. In actual use, the traction speed of the waste material may be too slow or even difficult to be pulled due to insufficient traction force. In addition, for the structure of the fixed lower fixed knife and the upper cutting knife in cooperation for cutting, when the position of the lower fixed knife is adjusted, it is relatively troublesome, and the adjustment accuracy is limited, and the situation of incomplete cutting is likely to occur. Summary of the Utility Model

[0004] In view of the deficiencies of the background art, the technical problem to be solved by the utility model is to provide a waste edge recycling mechanism of a heat pack machine for solving the above problems.

[0005] For this reason, the utility model is realized by the following scheme:

[0006] A waste edge recycling mechanism of a heat pack machine includes a mounting seat, characterized in that a feed inlet is opened on the mounting seat. A brush roller and a traction roller are arranged in the mounting seat near the feed inlet. A knife roller and a pressure roller are cooperatively arranged below the brush roller and the traction roller. A cutting knife is installed on the knife roller, and the cutting knife can cooperate with the pressure roller for waste edge cutting. A blanking hopper is arranged below the knife roller.

[0007] Traction teeth are circumferentially arranged on the outer side wall of the traction roller.

[0008] It further includes a driving motor. The output end of the driving motor is connected to the knife roller. One end of the knife roller is connected to a first gear. The first gear meshes with a second gear. The second gear is connected to the pressure roller. A first sprocket is also connected to the knife roller. The first sprocket is connected to a second sprocket through a chain. The second sprocket is connected to the traction roller.

[0009] The brush roller is rotatably arranged on the support shaft. Both ends of the support shaft are screwed to the corresponding screws. The screws are rotatably arranged on the mounting seat. A spring is tightly pressed between the mounting seat and the support shaft.

[0010] For the waste edge recycling mechanism of a heat shrink packaging machine with the above technical solution, by setting the structure of the traction roller cooperating with the brush roller for traction, the traction quality of the waste edge can be effectively improved. At the same time, the traction component and the cutting component are arranged up and down, so that the waste edge can be assisted by gravity to descend to the cutting component for cutting. At the same time, the cutting component uses the structure of the cutting knife on the knife roller cooperating with the pressure roller for cutting, which can also improve the cutting quality.

[0014] Figure 3 is Figure 1 a partial enlarged view of the position pointed by A in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] As shown in the figure, a waste edge recycling mechanism of a heat shrink packaging machine disclosed by the present utility model includes a mounting seat 6. A feed port 8 is provided on the mounting seat 6. A brush roller 9 and a traction roller 7 are arranged near the feed port 8 inside the mounting seat 6. A knife roller 5 and a pressure roller 3 are cooperatively arranged below the brush roller 9 and the traction roller 7. A cutting knife 4 is installed on the knife roller 5. The cutting knife 4 can cooperate with the pressure roller 3 to cut the waste edge. A blanking hopper 2 is arranged below the knife roller 5. Further, a traction tooth 18 is circumferentially arranged on the outer side wall of the traction roller 7, effectively improving the friction force between it and the waste edge and enhancing the traction quality. It also includes a driving motor 1. The output end of the driving motor 1 is connected to the knife roller 5. One end of the knife roller 5 is connected to a first gear 16. The first gear 16 meshes with a second gear 17. The second gear 17 is connected to the pressure roller 3. A first sprocket 15 is also connected to the knife roller 5. The first sprocket 15 is connected to a second sprocket 13 through a chain 14. The second sprocket 13 is connected to the traction roller 7. By controlling the motor 1 to start and transmitting through the gear set and the sprocket set, the knife roller 5, the pressure roller 3 and the traction roller 7 can be synchronously driven to rotate. The brush roller 9 is rotatably arranged on the support shaft 10. Both ends of the support shaft 10 are screwed to the corresponding screws 12. The screws 12 are rotatably arranged on the mounting seat 6. A spring 11 is tightly pressed between the mounting seat 6 and the support shaft 10. By controlling the rotation of the screw 12, the support shaft 10 can be driven to move, conveniently adjusting the distance between the brush roller 9 and the traction roller 7 to adapt to waste edges of different thicknesses or materials.

[0016] The working principle of the utility model is as follows: The waste edge first enters the mounting seat 6 from the feed inlet 8, and then is pulled downward under the cooperation of the traction roller 7 and the brush roller 9 and sent to the cutter roller 5. The rotation of the cutter roller 5 drives the cutting knife 4 to act in cooperation with the pressure roller 3 to cut the waste edge, and the waste edge cut into short strips is sent downward through the blanking hopper 2 into the collection box.

[0017] With this structure of the utility model, by setting the structure of the cooperation between the traction roller and the brush roller for traction, the traction quality of the waste edge can be effectively improved. At the same time, the traction component and the cutting component are arranged up and down, so that the waste edge can use gravity to assist in descending to the cutting component for cutting. At the same time, the cutting component uses the structure of the cutting knife on the cutter roller in cooperation with the pressure roller for cutting, which can also improve the cutting quality.
