Description

Technical Field

[0001] This application relates to the technical field of plastic pelletizers, and more particularly to a pelletizing bin for a plastic pelletizer. Background Technology

[0002] In the plastic granulation process, the plastic strip formed by the plastic extruder is cooled by a cooling water tank and then introduced into a plastic pelletizer to cut the plastic strip into plastic pellets.

[0003] Plastic pelletizers in related technologies, refer to Figure 1 and Figure 2 The system includes a frame 1, a pelletizing box 2 mounted on the frame 1, a cutter assembly 3 installed inside the pelletizing box 2, a power source 4 for driving the cutter assembly 3 to rotate on the pelletizing box 2, a discharge channel 5 at the bottom of the pelletizing box 2, and an opening 6 on one side of the pelletizing box 2 with a closing plate 7 bolted to it. The closing plate 7 has a feed channel 8 communicating with the inside of the pelletizing box 2, and a guide roller 9 on the feed channel 8 for separating and guiding plastic strips. The plastic strips are guided into the feed channel 8 by the guide roller 9, and then pass through the feed channel 8 to the cutter assembly 3, where the cutter assembly 3 cuts the plastic strips into plastic pellets, which are then discharged through the discharge channel 5.

[0004] Regarding the aforementioned technologies, when the plastic strip pelletizing is abnormal or the cutter assembly 3 needs maintenance, the closing plate 7 needs to be removed to open the opening 6 of the pelletizing box 2. The staff can then inspect or maintain the cutter assembly 3 through the opening 6. However, the closing plate 7 is fixed to the pelletizing box 2 by multiple bolts. Removing the closing plate 7 from the pelletizing box 2 requires unlocking multiple bolts one by one, which is quite troublesome and time-consuming. Utility Model Content

[0005] To improve the convenience of opening and closing the pelletizing bin, this application provides a pelletizing bin for a plastic pelletizer.

[0006] This application provides a pelletizing box for a plastic pelletizer, which adopts the following technical solution:

[0007] A pelletizing box for a plastic pelletizer includes a box body with an opening on one side. A closing plate for closing the opening is provided on the box body. A feeding channel is provided on the closing plate. One side of the closing plate is hinged to the box body. A connecting seat is provided on the other side of the closing plate. An insert rod is slidably connected to the connecting seat. A slot for inserting the insert rod is provided on the outer wall of the box body. When the closing plate closes the opening, the insert rod can extend out of the connecting seat and insert into the slot. A limiting component for limiting the insertion rod is provided on the connecting seat.

[0008] By adopting the above technical solution, the hinged connection between the closing plate and the box body allows the opening to be closed or opened by rotating the closing plate. Furthermore, by inserting the rod into the slot and limiting the rod, the connecting seat can be connected to the box body, making the closed plate stable and preventing the opening from moving. By releasing the limiting of the rod, the rod can disengage from the slot, allowing the closing plate to rotate and open the opening. This enables the pelletizing box to be opened quickly, improving the convenience of opening and closing the pelletizing box.

[0009] Optionally, the connecting seat is provided with a sliding hole for the insertion rod to slide through. The limiting component includes a limiting rod that slides on the connecting seat and an elastic element that drives the insertion rod to move. A first limiting groove is provided on the outer wall of the insertion rod. The connecting seat is provided with a moving groove on the inner wall of the sliding hole for the limiting rod to slide. The elastic element provides a driving force for the limiting rod to move to the sliding hole and insert into the first limiting groove. When the insertion rod is inserted into the slot, the limiting rod can be inserted into the first limiting groove.

[0010] By adopting the above technical solution, when the insert rod is inserted into the slot, the insert rod extends out of the connecting seat, and the limiting rod can be inserted into the first limiting groove under the action of the elastic element, thereby preventing the insert rod from disengaging from the slot and ensuring that the closing plate stably closes the opening. Pulling the limiting rod out of the insert rod allows the insert rod to slide out of the slot, causing the closing plate to rotate out of the opening.

[0011] Optionally, the end of the limiting rod away from the insertion rod is connected to a pull rod extending out of the connecting seat, and the elastic element includes a spring disposed in the moving groove, the spring being sleeved on the outer wall of the pull rod.

[0012] Optionally, the outer wall of the insertion rod is provided with a second limiting groove for the insertion of the limiting rod. When the insertion rod is inserted into the second limiting groove, the limiting rod is retracted into the moving groove.

[0013] By adopting the above technical solution, before the closing plate opens or closes the opening, the limiting rod is first inserted into the second limiting groove, and then the closing plate is closed or the opening is opened, thereby improving the stability of the closing plate when opening and closing the opening.

[0014] Optionally, the end of the insertion rod opposite to the slot is provided with an anti-detachment block, the side of the connecting seat opposite to the slot is provided with an anti-detachment groove for accommodating the anti-detachment block, and the housing is provided with a clearance groove on the inner wall of the slot for inserting the anti-detachment block.

[0015] By adopting the above technical solution, the anti-detachment block makes it less likely for the insertion rod to detach from the connector when it moves on the connector, thus improving the stability of the insertion rod.

[0016] Optionally, multiple connectors may be provided.

[0017] By adopting the above technical solution, multiple connectors can improve the connectivity when the closing plate closes the opening.

[0018] Optionally, a connecting rod is hinged to the housing, and a first magnetic block is provided at the end of the connecting rod away from its hinge point. A second magnetic block that attracts the first magnetic block is provided on the outer wall of the closed plate. When the closed plate is disengaged from the opening, the first magnetic block and the second magnetic block attract each other.

[0019] By adopting the above technical solution, the first magnetic block and the second magnetic block attract each other, making it difficult for the closed plate to move arbitrarily when it detaches from the opening, thus reducing the possibility that the closed plate may hinder the staff due to random rotation.

[0020] Optionally, the housing is provided with a receiving groove for accommodating the connecting rod.

[0021] By adopting the above technical solution, the receiving groove allows the connecting rod to be stored.

[0022] In summary, this application includes at least one of the following beneficial effects:

[0023] 1. By hinged to the box body and connected to the box body via the plug rod on the sliding connecting seat, the closing plate can be quickly opened or closed, improving the convenience of opening and closing the pelletizing box;

[0024] 2. The connecting rod and the closing plate are connected by a first magnetic block and a second magnetic block to improve the stability of the closing plate when it opens. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 3-9 This application will be described in further detail.

[0036] This application discloses a pelletizing bin for a plastic pelletizer. (Refer to...) Figure 3 A pelletizing box for a plastic pelletizer includes a hollow box body 10. The box body 10 has an opening 6 on one side. A closing plate 7 is hinged to the box body 10 at the opening 6. The closing plate 7 can rotate away from the opening 6 to open the opening 6. The closing plate 7 can also rotate to be inserted into the opening 6 to close the opening 6. A feeding channel 8 is fixedly provided on the closing plate 7. The feeding channel 8 has a guide roller 9 for guiding plastic strips into the box body 10. When the closing plate 7 closes the opening 6, the feeding channel 8 communicates with the inner cavity of the box body 10.

[0037] Reference Figure 3 and Figure 4 One side of the outer wall of the closing plate 7 is hinged to the box body 10 by a hinge. A connecting seat 11 is fixed to the outer wall of the closing plate 7 away from its own hinge point by bolts. Multiple connecting seats 11 are arranged in the vertical direction. In this embodiment, there are two connecting seats 11.

[0038] Reference Figure 5 One end of the connecting seat 11 extends out of the box body 10 and is slidably inserted with a rod 12. The sliding direction of the rod 12 is perpendicular to the surface of the closing plate 7. The connecting seat 11 is provided with a sliding hole 15 for the rod 12 to slide through.

[0039] Reference Figure 5 and Figure 6The outer wall of the housing 10 is provided with a slot 13 that mates with the insertion rod 12. When the end of the insertion rod 12 near the slot 13 moves into the sliding hole 15, the closing plate 7 can rotate into the opening 6, and the side of the connecting seat 11 near the closing plate 7 abuts against the outer wall of the housing 10. At this time, the insertion rod 12 is moved towards the housing 10, and the insertion rod 12 can pass through the connecting seat 11 and be inserted into the slot 13, thereby connecting the connecting seat 11 with the housing 10. The connecting seat 11 is provided with a limiting component 14 to limit the insertion rod 12, so that the insertion rod 12 is not easy to disengage from the slot 13 after being inserted into the slot 13.

[0040] Reference Figure 7 The limiting component 14 includes a limiting rod 141 that is slidably connected to the connecting seat 11 in the vertical direction, and an elastic element 142 that gives the limiting rod 141 a tendency to move toward the insert rod 12. The limiting rod 141 is located below the insert rod 12, and the sliding direction of the limiting rod 141 is perpendicular to the sliding direction of the insert rod 12. The connecting seat 11 has a moving groove 17 on the inner wall of the sliding hole 15 for the limiting rod 141 to slide, and the moving groove 17 does not penetrate the outer wall of the connecting seat 11.

[0041] Reference Figure 7 and Figure 8 The insertion rod 12 has a square structure, and a first limiting groove 16 is provided on the outer wall of the side opposite to the limiting rod 141 for the limiting rod 141 to be inserted. When the limiting rod 141 is inserted into the first limiting groove 16, the end of the insertion rod 12 near the closing plate 7 extends out to the connecting seat 11. Thus, when the insertion rod 12 is inserted into the slot 13 and the limiting rod 141 is inserted into the first limiting groove 16, the limiting rod 141 can restrict the insertion rod 12 from leaving the box 10 in the direction away from the box 10.

[0042] The elastic element 142 includes a spring 1421 connected to the limiting rod 141. The spring 1421 is located in the moving groove 17 and at the end of the limiting rod 141 away from the insertion rod 12. One end of the spring 1421 is connected to the end wall of the limiting rod 141 away from the insertion rod 12, and the other end of the spring 1421 is connected to the inner wall of the moving groove 17 away from the insertion rod 12. When the limiting rod 141 is inserted into the first limiting groove 16, the spring 1421 is in a compressed state.

[0043] Reference Figure 7In order to separate the limiting rod 141 from the insert rod 12 when the insert rod 12 needs to be moved, a pull rod 18 is fixed to the end wall of the limiting rod 141 away from the insert rod 12. The cross-sectional area of ​​the pull rod 18 is smaller than that of the limiting rod 141. The end of the pull rod 18 away from the limiting rod 141 slides downward through the lower surface of the connecting seat 11 and is fixed with a handle. A spring 1421 is sleeved on the part of the pull rod 18 located in the moving groove 17. Pulling the pull rod 18 away from the insert rod 12 can cause the limiting rod 141 to compress the spring 1421 and move away from the insert rod 12 into the moving groove 17, thereby separating the limiting rod 141 from the insert rod 12. In order to assemble the connecting seat 11 with the limiting rod 141 and the pull rod 18, the connecting seat 11 is formed by splicing the two halves together.

[0044] Reference Figure 6 and Figure 8 To improve the stability of the insertion rod 12, a handle is fixed to the end of the insertion rod 12 away from the closing plate 7, and anti-detachment blocks 20 are symmetrically fixed to the outer wall of the end of the insertion rod 12 near the closing plate 7. An anti-detachment groove 21 for accommodating the anti-detachment blocks 20 is opened on the outer wall of the connecting seat 11 near the closing plate 7. The anti-detachment groove 21 communicates with the sliding hole 15. A clearance groove 22 for sliding the anti-detachment blocks 20 is opened on the housing 10. The clearance groove 22 communicates with the slot 13. When the insertion rod 12 is pulled away from the housing 10, the anti-detachment blocks 20 can be fully accommodated and abutted into the anti-detachment groove 21, thereby preventing the insertion rod 12 from detaching from the connecting seat 11.

[0045] Reference Figure 7 and Figure 8 Furthermore, the insertion rod 12 has a second limiting groove 19 on its outer wall with the first limiting groove 16. The second limiting groove 19 is used for the insertion of the limiting rod 141. The second limiting groove 19 is closer to the anti-detachment block 20 than the first limiting groove 16. When the anti-detachment block 20 is accommodated in the anti-detachment groove 21, the second limiting groove 19 is connected to the moving groove 17. Under the elastic force of the spring 1421, the limiting rod 141 can be inserted into the second limiting groove 19, thereby restricting the end of the limiting rod 141 near the closing plate 7 from passing through the connecting seat 11, which facilitates the engagement of the closing plate 7 with the opening 6.

[0046] Reference Figure 9 To improve stability when the closed plate 7 separates from the opening 6, a receiving groove 26 is provided on the outer wall of the box body 10. A connecting rod 23 is hinged to the box body 10 in the receiving groove 26 by a pin. The outer wall of the connecting rod 23 is covered with a rubber layer. The friction between the rubber layer and the inner wall of the receiving groove 26 allows the connecting rod 23 to be housed in the receiving groove 26. Furthermore, the end of the connecting rod 23 away from its hinge point has a first magnet 24, and a second magnet 25 that can attract the first magnet 24 is fixed on the outer wall of the closed plate 7.

[0047] When the closing plate 7 rotates towards the direction of disengaging from the opening 6, it gradually approaches the connecting rod 23. Rotating the connecting rod 23 out of the receiving groove 26 allows the first magnetic block 24 and the second magnetic block 25 to attract each other. When the first magnetic block 24 and the second magnetic block 25 attract each other, the closing plate 7 disengages from the opening 6, so that when the operator operates the cutter assembly 3 through the opening 6, the closing plate 7 is not easily moved and causes obstruction.

[0048] The implementation principle of the pelletizing box 2 of a plastic pelletizer in this application embodiment is as follows: pull down the pull rod 18 to disengage the limiting rod 141 from the first limiting groove 16, and then pull the insert rod 12 away from the box body 10 so that the anti-detachment block 20 abuts into the anti-detachment groove 21, thereby separating the insert rod 12 from the box body 10. Under the elastic force of the spring 1421, the limiting rod 141 is inserted into the second limiting groove 19. After the insert rod 12 is separated from the box body 10, the closing plate 7 is rotated out of the box body 10 to open the opening 6, and the connecting rod 23 is rotated out from the receiving groove 26 so that the first magnetic block 24 and the second magnetic block 25 attract each other.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
