[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1-5 As shown, the utility model provides a technical solution: a plastic bag production raw material particle mixing device, comprising: a stirring mechanism 1, the stirring mechanism 1 includes a motor 11, the lower end of the motor 11 is rotatably connected to a rotating shaft 12, the upper end of the outer wall of the rotating shaft 12 is fixedly connected to a gear 13, the outer wall of the rotating shaft 12 is fixedly connected to a cutting blade 14, a slot 15 is provided on the rotating shaft 12, a cavity 16 is provided inside the rotating shaft 12, a stirring box 2 is provided at the lower end of the stirring mechanism 1, and the slot 15 provided on the rotating shaft 12 is in the stirring box 2 On one side of the interior, a rotating rod 3 is provided on the inner wall of the mixing box 2, a gear 2 4 is fixedly connected to the outer wall of the upper end of the rotating rod 3, a gear 13 is provided on the outer wall of the upper end of the rotating shaft 12 and meshes with the gear 2 4, a cutting blade 2 5 is fixedly connected to the outer wall of the rotating rod 3 away from the gear 2 4, the inner wall of the mixing box 2 is movably connected to the rotating shaft 12, and a rotating rod 3, a gear 2 4 and a cutting blade 2 5 are provided on both sides of the rotating shaft 12, and the cutting blade 2 5 provided on the outer wall of the rotating rod 3 interacts with the cutting blade 14 provided on the outer wall of the rotating shaft 12.

[0026] In this example, during the manufacturing process, it is necessary to prepare and process raw materials, usually in the form of granules or granular materials. These raw material granules are put into the equipment for stirring and mixing, and then extruded by an extrusion device to obtain plastic bags. However, the current problem is that when the raw material particles are mixed, the particles cannot be completely cut into pieces and effectively and evenly mixed together, which affects the quality and appearance of the final product. Therefore, a stirring mechanism 1 is provided, wherein the stirring mechanism 1 includes a motor 11, and a rotating shaft 12 is provided at the lower end of the motor 11. When the motor 11 is started, the rotating shaft 12 will be driven to rotate, and the rotating shaft 12 will drive the gear 13 and the cutting blade 14 provided on the outer wall to rotate together. In order to enable the raw material particles to be completely cut into pieces for the convenience of subsequent uniform mixing, two rotating rods 3 are provided inside the mixing box 12, and the two rotating rods 3 are respectively distributed on both sides of the rotating shaft 12, and the gear 2 4 provided on the upper end of the outer wall of the rotating rod 3 is correspondingly connected with the gear 13 provided on the outer wall of the upper end of the rotating shaft 12. When the rotating shaft 12 rotates, the gear 13 will drive the gear 2 4 to engage, so that the cutting blade 2 5 provided on the outer wall of the rotating rod 3 interacts with the cutting blade 14 provided on the outer wall of the rotating shaft 12, thereby crushing the raw material particles;

[0027] The crushed raw material particles need to be transported to the mixing box 2 7 below for mixing and mixing. For this purpose, a number of slots 15 are opened on the rotating shaft 12, and a cavity 16 is opened in the rotating shaft 12. The positions of the slots 15 on the rotating shaft 12 are limited to the mixing box 1 2. Therefore, when the crushed raw material particles enter the cavity 16 opened in the rotating shaft 12 through the slots 15, and enter the mixing box 2 7 through the cavity 16, the mixing and mixing process is carried out. The slots 15 are opened in uniform sizes, and only particles that meet the size requirements will enter them and enter the next process, while those that do not meet the size requirements will be repeatedly cut and crushed by the cutting blade 2 5 and the cutting blade 1 14 until they meet the requirements and can enter and be transported out.

[0028] Example 2

[0029] like Figure 2-5 As shown, a stirring block 17 is fixedly connected to the outer wall of the lower end of the rotating shaft 12, a stirring sheet 18 is fixedly connected to one side of the stirring block 17, a connecting column 19 is fixedly connected to the lower end of the stirring block 17, a connecting block 6 is fixedly connected to the lower end of the stirring box 12, a side of the connecting block 6 away from the stirring box 12 is fixedly connected to the stirring box 2 7, the stirring block 17 is slidingly connected to the inner wall of the stirring box 2 7, the lower end of the connecting column 19 provided at the lower end of the stirring block 17 is rotatably connected to the bottom of the inner wall of the stirring box 2 7, a discharging device 8 is connected to the lower end of the stirring box 2 7, and a supporting foot 9 is fixedly connected to the outer wall of the lower end of the stirring box 2 7.

[0030] In this example, the crushed raw material particles need to be uniformly stirred and mixed by design, so as to obtain plastic bags of qualified quality. The crushed raw material particles enter the mixing box 2 7 through the cavity 16 in the rotating shaft 12. At this time, the motor 11 is started, and the motor 11 will drive the rotating shaft 12 to rotate. While the rotating shaft 12 rotates, it will drive the stirring block 17 connected to the outer wall of the lower end to rotate on the inner wall of the mixing box 2 7. The stirring block 17 forms a C shape, and four stirring blades 18 are evenly arranged in the middle. When the stirring block 17 rotates, it will drive the stirring blades 18 to rotate, so that the raw material particles inside are uniformly stirred. The lower end of the stirring block 17 is connected to a connecting column 19, which is connected to the bottom of the mixing box 2 7, and can connect and limit the stirring block 17 to ensure that the stirring block 17 can operate stably.

[0031] During the rotation of the stirring block 17 and the stirring blade 18, it is found that although the particles can be stirred and mixed, the inner wall of the stirring box 7 will adsorb the particles, resulting in the particles adsorbed on the inner wall being carried out together with the stirred raw materials when they are transported out. After subsequent operations, a plastic bag with uneven material will be obtained. Therefore, the stirring block 17 is designed to be attached to the inner wall of the stirring box 7. When rotating, the particles adsorbed on the inner wall of the stirring box 7 will be scraped off and mixed and stirred to obtain evenly stirred raw materials, which are then transported out through the discharging device 8 provided at the lower end of the stirring box 7 to proceed to the next step.

[0032] Working principle:

[0033] like Figure 1-5 As shown, when the utility model is in use, the raw material particles are put into the mixing box 2, and the motor 11 is started at this time. The motor 11 drives the rotating shaft 12 to rotate. When the rotating shaft 12 rotates, it will drive the gear 13 connected to the upper end of the outer wall to rotate, and the gear 13 will drive the gear 24 provided on both sides to mesh and rotate with the rotating rod 3. At this time, the cutting blade 25 provided on the outer wall of the rotating rod 3 will rotate and interact with the cutting blade 14 provided on the outer wall of the rotating shaft 12, so that the raw material is cut and crushed into powder or fragments of appropriate size, which enter the cavity 16 through the cutting blade 25 of the motor 11 opened on the rotating shaft 12, and are transmitted to the mixing box 2 7 through the cavity 16. Since the rotating shaft 12 rotates, it will drive the stirring block 17 connected to the outer wall of the lower end to rotate together. The stirring block 17 is close to the inner wall of the mixing box 2 7 to scrape off the particles adsorbed on the inner wall and cooperate with the stirring blade 18 to repeatedly stir and mix, so as to obtain uniformly stirred raw materials, and transport them out through the discharging device 8 provided at the lower end of the mixing box 2 7 to proceed to the next step.

Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
