Description
Technical Field
[0001] The present application relates to the field of pelletizers, and in particular to a knife roll installation mechanism for a pelletizer. Background Art
[0002] Pelletizers are mainly used for processing waste basins, barrels, beverage bottles, furniture, daily necessities, etc. They are the most widely used, most popular, and most favored plastic recycling processing machines in the waste plastic recycling industry. When granulating, a pelletizer hob is required to cut strip-shaped plastics into granular form.
[0003] The utility model patent with the publication number CN209682685U proposes a detachable pelletizer hob, which includes a rubber roll and a second spring. A connection groove is opened inside the rubber roll, and frames are arranged on both sides of the rubber roll. A first spring is arranged in the middle of the connection groove. Among them, connection shafts are connected to both sides of the spring. Sliding grooves are opened on both sides of the rubber roll close to the connection shafts, and sliding plates are fixed on one side of the connection shafts close to the sliding grooves. A spring groove is opened on the opening side of the rubber roll close to the connection groove.
[0004] For the above-mentioned detachable pelletizer hob, through the connection groove, connection shaft, fixed rod and fixed groove, the connection shaft is pushed to move the connection shaft into the inside of the connection groove, and the first spring is compressed. At the same time, the connection shaft drives the fixed groove to move towards the connection groove. When the connection shaft drives the fixed groove to reach the position of the spring groove, the second spring pushes the fixed rod into the inside of the fixed groove by elastic force to prevent the connection shaft from continuing to move, facilitating the separation of the connection shaft from the frame, facilitating disassembly, and preventing the problem that the knife roll is cumbersome during disassembly or installation, resulting in reduced work efficiency. The present application provides another solution to solve this problem. Utility Model Content

DETAILED DESCRIPTION
[0030] The following is combined withFigure 1 - Figure 1 Further detailed description of the present application is provided.
[0031] An embodiment of the present application discloses a knife roll mounting mechanism for a pelletizer.
[0032] Referring to Figure 1 and Figure 2 , a knife roll mounting mechanism for a pelletizer includes two mounting frames 1 and a knife roll body 2. Mounting components for conveniently mounting the knife roll body 2 onto the mounting frames 1 are provided on the mounting frames 1 and the knife roll body 2. The mounting components include receiving grooves 3 opened on the opposite sides of the two mounting frames 1, and grooves 4 communicated with the receiving grooves 3 are opened at the tops of the mounting frames 1. Limiting components are provided at both ends of the knife roll body 2. The limiting components include limiting discs 16. Fixing plates 5 are sleeved on both ends of the knife roll body 2 through the limiting components. After the knife roll body 2 is placed into the mounting frames 1 through the grooves 4, the fixing plates 5 are opposite to the receiving grooves 3. At the same time, the fixing plates 5 cannot move on the knife roll body 2 through the limiting components and can only rotate. Clamping plates 6 inserted into the receiving grooves 3 are provided on the side walls of the two fixing plates 5 facing each other. The clamping plates 6 can move back and forth on the knife roll body 2. A plurality of first springs 7 for pushing the clamping plates 6 into the receiving grooves 3 are provided between the fixing plates 5 and the clamping plates 6, so that the clamping plates 6 are inserted into the receiving grooves 3 to mount the knife roll body 2.
[0033] Referring to Figure 2 , pull rods 8 are provided in the first springs 7. One end of each pull rod 8 is fixedly connected to the corresponding clamping plate 6, and the other end of the pull rod 8 penetrates through the fixing plate 5. By pulling the pull rods 8, the clamping plates 6 can be made to approach the fixing plates 5, causing the first springs 7 to contract, preventing the clamping plates 6 from being difficult to pull out when they are located in the receiving grooves 3.
[0034] Referring to Figure 2 , two vertically arranged insertion plates 9 are fixedly connected to the side wall of the clamping plate 6 close to the receiving groove 3. Two slots 10 respectively adapted to the insertion plates 9 are opened on the side wall of the receiving groove 3 close to the clamping plate 6. The clamping plates 6 are positioned through the insertion plates 9 and the slots 10, which can improve the stability of the clamping plates 6 and prevent the knife roll body 2 from shaking when rotating.
[0035] Referring to Figure 1 , insertion rods 11 are provided on both side walls of the mounting frames 1. One end of each insertion rod 11 penetrates through the mounting frame 1 and is inserted into the corresponding insertion plate 9. The insertion rods 11 can prevent the clamping plates 6 from disengaging from the receiving grooves 3 during use.
[0036] Referring to Figure 3, a return-shaped frame 12 is sleeved on the insertion rod 11. One side wall of the return-shaped frame 12 is fixedly connected to the mounting rack 1. A push-pull plate 13 is arranged inside the return-shaped frame 12. The push-pull plate 13 is fixedly connected to the insertion rod 11. A second spring 14 is fixedly connected to the side wall of the push-pull plate 13 away from the mounting rack 1. The insertion rod 11 is located inside the second spring 14. One end of the second spring 14 away from the push-pull plate 13 is fixedly connected to the return-shaped frame 12. By pulling the insertion rod 11, the second spring 14 is contracted, the insertion rod 11 is separated from the insertion plate 9, and after the clamping plate 6 is taken out, the insertion rod 11 can be inserted into the insertion slot 10 by the rebound of the second spring 14 to prevent the insertion rod 11 from falling and being lost.
[0037] Referring to Figure 1 and Figure 2 , a telescopic tube 15 is sleeved on the first spring 7. Two ends of the telescopic tube 15 are respectively fixedly connected to the clamping plate 6 and the fixing plate 5. The first spring 7 can be protected through the telescopic tube 15.
[0038] Referring to Figure 1 , four limiting discs 16 are provided and are respectively located on both sides of the fixing plate 5. The limiting discs 16 are threadedly connected to the cutter roller body 2. The fixing plate 5 can be rotationally limited on the cutter roller body 2 through the limiting discs 16 to prevent the fixing plate 5 from moving. At the same time, the fixing plate 5 and the clamping plate 6 can be removed from the cutter roller body 2 by rotating the limiting discs 16.
[0039] Referring to Figure 1 , a connecting groove 17 is opened at one end of the cutter roller body 2, which is convenient for an external driving device to be connected to the cutter roller body 2 to drive the cutter roller body 2 to rotate.
[0040] The implementation principle of the cutter roller mounting mechanism of the cutting machine in the embodiment of the present application is as follows: During use, by pulling the clamping plate 6, the first spring 7 is squeezed to make the clamping plate 6 close to the fixing plate 5. Then, both ends of the cutter roller body 2 are placed into the mounting rack 1 through the grooves 4. Then, the clamping plate 6 is released to make the first spring 7 rebound. The clamping plate 6 is inserted into the receiving groove 3, and at the same time, the insertion plate 9 is inserted into the insertion slot 10. Then, the insertion rod 11 is inserted into the insertion plate 9 to fix the clamping plate 6, quickly mounting the cutter roller body 2, and at the same time facilitating disassembly, and avoiding as much as possible the problem that the cutter roller is cumbersome during disassembly or installation, resulting in reduced work efficiency.
[0041] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
