[0023] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] Reference Figure 1-6 A masterbatch pelletizer includes a pelletizer body 1, with two extrusion blocks 2 slidably disposed inside the pelletizer body 1. A driving mechanism is disposed between the two extrusion blocks 2, and a pelletizing mechanism is disposed inside the pelletizer body 1. In use, the masterbatch strips are cooled and shaped before entering the pelletizer to be pelletized. The driving mechanism drives the two extrusion blocks 2 to approach each other and squeeze and clamp the masterbatch strips. After being fixed and clamped, they are pushed to the pelletizing mechanism for pelletizing. The bottom of the extrusion blocks 2 has multiple grooves that are adapted to the masterbatch strips. When clamping and conveying the masterbatch strips, this device can increase the contact area between the clamping mechanism and the masterbatch strips, protect the masterbatch strips from deformation, and improve product quality.
[0025] As a preferred embodiment, the pelletizing mechanism includes a roller cutter 3, which is rotatably installed inside the pelletizer body 1. A first motor 4 is fixedly installed on the side wall of the pelletizer body 1, and the output end of the first motor 4 passes through the side wall of the pelletizer body 1 and is fixedly connected to the roller cutter 3. A support plate 5 is fixedly installed inside the pelletizer body 1, and the edge of the support plate 5 is tangent to the edge of the roller cutter 3. When the masterbatch strip enters the pelletizer body 1, it is conveyed to the support plate 5 with the cooperation of the extrusion block 2 and the drive mechanism. The part of the masterbatch strip that extends out of the support plate 5 is continuously pelletized by the rapidly rotating roller cutter 3, thus completing the masterbatch processing process.
[0026] As a preferred embodiment, the driving mechanism includes two driving plates 6, which are slidably installed inside the pelletizer body 1. Driving grooves 7 are provided on the two driving plates 6. Driving rods 8 are fixedly installed at both ends of the two extrusion blocks 2. Multiple driving rods 8 are respectively disposed inside the driving grooves 7. Limiting plates 9 are slidably installed on both sides of the inner wall of the pelletizer body 1. The driving rods 8 at both ends of the two extrusion blocks 2 are slidably connected to the two limiting plates 9. When the driving mechanism is in use, by pushing the two driving plates 6 to move, the two extrusion blocks 2 move closer together under the cooperation of the driving grooves 7 and the driving rods 8, extruding the masterbatch strips. Then, moving the driving plates 6 pushes the two extrusion blocks 2, causing the masterbatch strips to move. The limiting plates 9 are used to limit the movement of the two driving rods 8, ensuring that the two driving rods 8 can only move in the vertical direction.
[0027] As a preferred technical solution of this embodiment, the inner walls of both sides of the pelletizer body 1 are provided with sliding grooves 10, the limiting plate 9 is slidably installed inside the sliding grooves 10, and two sliding rods 11 are fixedly installed on the side wall of the limiting plate 9. The two sliding rods 11 are slidably connected to the pelletizer body 1, and a first spring 12 is fixedly installed between the two sliding rods 11 and the pelletizer body 1. When the drive plate 6 moves and moves in coordination with the drive groove 7 and the drive rod 8 to bring the two extrusion blocks 2 closer to each other, the first spring 12 and the sliding rods 11 support the limiting plate 9 to ensure the stability of the limiting plate 9.
[0028] As a preferred embodiment, the top and bottom of the slide groove 10 away from the end near the roller cutter 3 are slidably equipped with locking blocks 13. A second spring 14 is fixedly connected between the locking blocks 13 and the side wall of the pelletizer body 1. A pushing block 15 and a stop block 16 are fixedly installed on the drive plate 6. A limiting plate 9 is disposed between the pushing block 15 and the stop block 16. After the drive plate 6 drives the two extrusion blocks 2 to approach each other, the pushing block 15 contacts the limiting plate 9. As the drive plate 6 moves... The limiting plate 9 is pushed by the pushing block 15. When the limiting plate 9 moves to the end of the slide 10, the locking block 13 will lock the limiting plate 9. Therefore, when the driving plate 6 drives the two extrusion blocks 2 to reset, the two extrusion blocks 2 will first separate from each other. Then the stop block 16 will contact the limiting plate 9 and push the limiting plate 9 past the stop block 16, so that the limiting plate 9 will also complete the reset. During the reset process of the extrusion blocks 2, they will first separate from each other, so they will not contact the color masterbatch strip during the reset process, so that the color masterbatch strip will only be continuously conveyed forward.
[0029] As a preferred embodiment, a connecting plate 17 is fixedly installed on the top of the two drive plates 6. The connecting plate 17 is slidably disposed inside the pelletizer body 1. A movable groove 18 is provided on the connecting plate 17. A connecting rod 19 is slidably installed inside the movable groove 18. A disc 20 is fixedly installed on the top of the connecting rod 19. The connecting rod 19 is fixedly installed on one side of the bottom of the disc 20. A second motor 21 is fixedly installed on the top of the pelletizer body 1. The output end of the second motor 21 passes through the top of the pelletizer body 1 and is fixedly connected to the disc 20. The disc 20 driven by the second motor 21 rotates, causing the connecting rod 19 to reciprocate, thereby causing the two drive plates 6 to drive the extrusion block 2 to reciprocate.
[0030] As a preferred technical solution in this embodiment, a receiving port 22 is fixedly installed at the bottom of the pelletizer body 1, and the receiving port 22 is fixedly installed directly below the roller cutter 3; the cut masterbatch is guided and collected through the receiving port 22.
[0031] As a preferred technical solution in this embodiment, multiple rubber sleeves 23 are fixedly installed at the bottom of both extrusion blocks 2; by installing rubber sleeves 23 inside the groove of the extrusion block 2, the friction between the extrusion block 2 and the masterbatch strip is increased, making the conveying of the masterbatch strip more stable.
[0032] Working principle:
[0033] The entire operation process of this device is as follows: the masterbatch strips enter the pelletizer body 1, and are squeezed and held by the extrusion block 2. The output end of the second motor 21 drives the disc 20 to rotate, which, in conjunction with the connecting rod 19 and the movable groove 18 of the connecting plate 17, allows the two drive plates 6 to reciprocate. During the forward movement of the two extrusion blocks 2, the drive groove 7, the drive rod 8, and the limiting plate 9 cooperate to first bring the two extrusion blocks 2 closer together to squeeze and fix the masterbatch strips. Then, the push block 15 pushes the limiting plate 9 to cooperate with the movement of the extrusion blocks 2, so that the masterbatch strips are conveyed to the roller cutter 3 to complete the pelletizing. During the reset process, the locking block 13 simply limits the limiting plate 9, so that during the reset process, the drive plate 6, the drive groove 7, and the drive rod 8 cooperate to first separate the extrusion blocks 2. This prevents the extrusion blocks 2 from contacting the masterbatch strips during the reset process, thereby continuously conveying the masterbatch strips forward to complete the pelletizing.
[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
