[0022] Example
[0023] The utility model provides an improved grinding device for the production of polyamide polyester film. Figure 1-4 As shown, it includes a grinding box 2 and a filter box 1 connected thereto, the top of the grinding box 2 is provided with a feed hopper 3 connected to its inner cavity, and two oppositely arranged grinding rollers 4 are rotatably connected to the inner wall of the grinding box 2, and a first guide inclined plate 5 is provided on the inner wall of the grinding box 2 above the grinding roller 4, which gradually tilts inward from one end close to the feed hopper 3 to the end away from the feed hopper 3, so that the film raw material to be ground can be guided and transported to between the two grinding rollers 4 for grinding treatment, and a material guide plate 6 is provided on the inner wall of the grinding box 2 below the two grinding rollers 4, one end of the material guide plate 6 passes through the grinding box 2 and extends into the filter box 1 and is connected to the material conveying pipe 17, and through the setting of the material guide plate 6, the ground film raw material can be transported to the filter box 1 for filtration treatment, and the inner wall of the material guide plate 6 is an arc-shaped structure.
[0024] During use, the film raw material to be ground is poured into the feed hopper 3, and the two first guide inclined plates 5 guide the film raw material to be ground to between the two grinding rollers 4. The two grinding rollers 4 are driven by an external drive motor to rotate to grind the film raw material. The ground film raw material falls onto the guide plate 6, and the ground film raw material is transported to the filter box 1 through the guide plate 6 for filtration, thereby preventing large particles of film raw material from affecting the next process after discharge.
[0025] A rotating motor 7 is provided on the top end face of the filter box 1, and the output end of the rotating motor 7 extends to the inner cavity of the filter box 1 and is provided with a rotating shaft 8. A filter frame 9 with a hollow rectangular structure is sleeved on the outside of the rotating shaft 8, and the filter frame 9 is fixed to the rotating shaft 8 by a plurality of evenly distributed connecting rods 11. A filter plate 10 is hingedly connected to it at one end at the bottom of the filter frame 9, and a feeding pipe 17 with a hollow cylindrical structure is provided on the inner wall of the filter box 1 above the filter frame 9. Two symmetrically arranged second guide inclined plates 13 are provided on the inner wall of the filter box 1 below the filter frame 9. Through the setting of the second guide inclined plates 13, the film raw materials can be guided to fall into the collection frame 15 to avoid splashing of the film raw materials. A removable sliding sleeve is provided on the filter box 1 below the second guide inclined plate 13. Through the setting of the collection frame 15, the film raw materials after filtration can be collected.
[0026] Furthermore, a plurality of filter holes 12 are provided on the filter frame 9 and the filter plate 10. Through the setting of the filter holes 12, the film raw materials that meet the discharge standards can be filtered out, and the large particles of the film raw materials can be collected so that the large particles of the film raw materials can be ground again later.
[0027] Furthermore, a plurality of evenly distributed mounting plates 19 are provided on one side of the bottom of the filter frame 9 and one side of the filter plate 10. The mounting plates 19 are penetrated with mounting threaded holes for inserting quick-release bolts 14. The arrangement of the mounting threaded holes and the quick-release bolts 14 on the mounting plates 19 makes it convenient for staff to take out large particles of film raw materials in the filter frame 9 for re-grinding.
[0028] Furthermore, a door leaf 18 is hingedly provided on one side of the filter box 1. The door leaf 18 makes it convenient for the staff to maintain and repair the components inside the filter box 1, and also makes it convenient for the staff to take out the large particles of film raw materials and grind them again.
[0029] Furthermore, a guide block with a trapezoidal structure is provided on the outer wall of the aggregate frame 15, and a guide groove 16 adapted to the guide block is opened on the inner wall of the filter box 1. Through the setting of the guide groove 16 and the guide block, the connection strength and stability between the aggregate frame 15 and the filter box 1 are improved.
[0030] During use, the ground film raw material falls into the filter frame 9 along the feed pipe 17, and the rotating motor 7 is started to drive the rotating shaft 8 and the filter frame 9 to rotate. During the rotation process, the film raw material that meets the discharge size flies out from the filter hole 12 and falls into the collection frame 15 through the second guide inclined plate 13. At the same time, during the rotation process, the film raw material hits the inner wall of the filter frame 9 and the connecting rod 11, which can break up the film raw material agglomerated after grinding, thereby improving the discharge quality of the film raw material.
[0031] When there are too many large-particle film raw materials in the filter frame 9, which affects the filtering effect, the staff will remove the film raw materials that meet the discharge standards in the aggregate frame 15, then open the door 18 on the filter box 1, and turn the quick-release bolts 14 plugged into the two mounting plates 19 to remove them. Then, rotate the filter plate 10 to make the large-particle film raw materials in the filter frame 9 fall into the aggregate frame 15 through the second guide inclined plate 13. The staff will put the large-particle film raw materials in the aggregate frame 15 into the grinding box 2 for further grinding, thereby ensuring the discharge quality of the film raw materials.
[0032] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0033] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
