[0025] The mounting assembly 8 includes a fixing plate 801, a mounting plate 802, a threaded rod 803, and a fastening block 804. The fixing plate 801 is provided on the inner wall of the housing 1. The mounting plate 802 and the threaded rod 803 are provided on one side of the fixing plate 801. The threaded rod 803 facilitates the installation of the mounting plate 802. The fastening block 804 is provided on the threaded rod 803.

[0026] In this embodiment, the rotating rod 12 is fixedly installed on one side of the cam 2, and the positioning block 13 is fixedly installed on the inner wall of the housing 1;

[0027] Specifically, the rotating rod 12 facilitates the connection between the cam 2 and the positioning block 13;

[0028] In this embodiment, a slot adapted to the cam 2 is provided on one side of the replacement shell 9, and an opening adapted to the rotating rod 12 is provided on the other side of the replacement shell 9 and one end of the positioning block 13.

[0029] Specifically, the positioning block 13 prevents the replacement shell 9 from disengaging from the cam 2 during rotation;

[0030] In this embodiment, the cam 2 is engaged in the replacement housing 9 and the rotating rod 12 is engaged in the positioning block 13 after passing through the replacement housing 9. One side of the positioning block 13 is in contact with one side of the replacement housing 9.

[0031] Specifically, replacing shell 9 can prevent cam 2 from needing to be replaced entirely due to wear on both sides;

[0032] In this embodiment, the fixing plate 801 is fixedly installed on one side of the inner wall of the housing 1, and two sets of threaded rods 803 are fixedly installed on one side of the fixing plate 801.

[0033] Specifically, the fixing plate 801 facilitates the installation of the threaded rod 803;

[0034] In this embodiment, one end of the mounting plate 802 is sleeved and fixed to the mounting end of the motor 3, and the other end of the mounting plate 802 is provided with an opening adapted to the two sets of threaded rods 803. This opening is not a threaded hole. The other end of the mounting plate 802 is sleeved on the two sets of threaded rods 803. The fastening block 804 is provided with a threaded hole adapted to the threaded rod 803. The fastening block 804 is in the shape of a "plum blossom". The two sets of fastening blocks 804 are respectively threadedly connected to the two sets of threaded rods 803.

[0035] Specifically, mounting plate 802 facilitates the installation of motor 3;

[0036] In this embodiment, the square rod 11 is fixedly installed at the output end of the motor 3, and the square groove 10 is adapted to the square rod 11, with the square rod 11 snapped into the square groove 10.

[0037] Specifically, the square groove 10 combined with the square rod 11 can prevent the cam 2 from rotating on its own, thereby making the cam 2 rotate synchronously with the motor 3.

[0038] The working principle and usage process of this utility model are as follows: The operator first checks whether the relevant components are installed in the correct position. The motor 3 is controlled to rotate by the control device. The square groove 10 combined with the square rod 11 can prevent the cam 2 from rotating on its own, so that the cam 2 rotates synchronously with the motor 3. Since the square groove 10 does not penetrate to the other side, it can prevent the installed cam 2 from moving towards the motor 3. The rotating rod 12 combined with the positioning block 13 can prevent the installed cam 2 from moving towards the positioning block 13 without affecting the rotation of the cam 2, so that the cam 2 is fixed at the output end of the motor 3. The rotation of the cam 2 causes different parts on both sides of the cam 2 to press the two sets of moving plates 4. Combined with the spring on the corresponding slide rod, the moving plate 4 can move back and forth left and right. The guide wire frame 5 moves back and forth left and right, so that the plastic winding material wound on the guide wire frame 5 is evenly wound back and forth on the winding frame 6, so that the plastic packaging material can be wound up.

[0039] When it is necessary to replace the cam 2 with a different specification later, open the sealing door 7 and rotate the two sets of fastening blocks 804 in sequence to disengage them from the threaded rod 803. The plum blossom design of the fastening blocks 804 makes it easier for the operator to rotate them manually. Move the mounting plate 802 outward to disengage it from the threaded rod 803 and the square rod 11 from the square groove 10. Move the cam 2 outward to disengage the rotating rod 12 from the positioning block 13 to complete the disassembly of the cam 2. The above operations can be reversed to install the cam 2, which is quite convenient. This structure facilitates the disassembly and assembly of the cam 2, and makes it convenient to replace the cam 2 with different specifications according to different production needs or material specifications later.

[0040] Furthermore, during the rotation of cam 2, replacement shell 9 will replace cam 2 in frictional contact with the two sets of moving plates 4. Later, only replacement shell 9 needs to be replaced. When replacing replacement shell 9, first remove cam 2 from housing 1, and then move replacement shell 9 outward to detach it from cam 2. The above operation can be reversed to complete the installation of replacement shell 9. After installation, the bottom limiting effect of the opening of replacement shell 9 can prevent replacement shell 9 from moving towards motor 3 during the rotation of cam 2. One side of positioning block 13 is attached to one side of replacement shell 9, which can prevent replacement shell 9 from moving towards positioning block 13 during rotation, thereby fixing replacement shell 9 on cam 2. This structure uses replacement shell 9 to replace cam 2 to bear wear, and only replacement shell 9 needs to be replaced later, which can reduce material waste.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
