Description

Technical Field

[0001] This application relates to the field of mold-locking devices, and in particular to a mold-locking device for an underwater pelletizer. Background Technology

[0002] An underwater pelletizer is a device specifically designed for cutting materials in underwater environments, and it has a wide range of applications in various fields.

[0003] A Chinese patent with authorization publication number CN210791620U discloses a mold-locking device for an underwater pelletizer. The underwater pelletizer has a connecting base and a water chamber, and includes a connecting body and a locking disc. At least two locking blocks are provided along the outer circumference of the connecting body, and corresponding stops are provided along the inner circumference of the locking disc near the end of the connecting body. A notch is formed between adjacent stops to allow the locking blocks to extend into the locking disc. The connecting body is fixed to one of the connecting base and the water chamber, and the locking disc is rotatably fitted onto the other. After the locking blocks extend into the locking disc, the locking disc is rotated to align the stops with the locking blocks, thereby locking the connecting base and the water chamber.

[0004] In the aforementioned underwater pelletizer, during mold locking, the connecting seat is moved closer to the water chamber. After the clamping block is positioned inside the locking disc, the locking disc is rotated to align the stop block with the clamping block, thus limiting the clamping block's position. However, rotating the locking disc primarily relies on the operator pulling an operating lever on the locking disc to achieve mold locking. Each mold locking and disengagement requires operator intervention, resulting in inconvenience during these processes. Utility Model Content

[0005] To improve the convenience of mold locking and mold opening, this application provides a mold locking device for an underwater pelletizer.

[0006] The clamping device for an underwater pelletizer provided in this application adopts the following technical solution:

[0007] A locking device for an underwater pelletizer includes a connecting body and a locking disc. The connecting body has multiple locking blocks circumferentially arranged along its own axis, and the locking disc has multiple stops circumferentially arranged along its own axis. A notch for inserting a locking block is formed between adjacent stops. The device is characterized by further including a locking disc position monitoring component and a processor.

[0008] The locking disc moves closer to or away from the connecting body along a predetermined route via a linear power source, and rotates around its own axis via a rotary power source.

[0009] Both the locking disc rotation power source and the locking disc monitoring component are electrically connected to the processor.

[0010] Optionally, the power source for rotating the locking disc includes a rotating gear ring and a rack, wherein:

[0011] The rotating gear ring is coaxially mounted on the outer circumferential surface of the locking disc;

[0014] Optionally, the guide seat is mounted on the mounting platform, the guide seat is U-shaped, and the opening of the guide seat faces the rotating gear ring. The rack is placed on the guide seat and slides with the guide seat.

[0015] Optionally, the inner wall of the guide seat is provided with a plurality of friction-reducing protrusions that contact the rack on the side near the rack.

[0016] Optionally, the plurality of friction-reducing protrusions are distributed along the width direction of the rack, and the length direction of the friction-reducing protrusions is consistent with the length direction of the rack, and the cross-sectional area of ​​the friction-reducing protrusions gradually decreases in the direction away from the rack.

[0017] Optionally, a conveying platform is provided near the locking disc, and the locking disc rotates with the conveying platform. The locking disc position monitoring component includes a follower rod and a distance monitoring sensor, wherein:

[0018] One end of the follower rod is mounted on the locking disc;

The end of the follower rod away from the locking disc is placed inside the linear limiting groove, slides with the linear limiting groove, and rotates with the rotary guide groove.

[0021] Optionally, the follower rod is detachably and fixedly connected to the locking disc via a connector, the connection including a connecting sleeve and a connecting bolt, wherein:

[0022] One end of the connecting cylinder is mounted on the locking disc, and one end of the follower rod is inserted into the connecting cylinder.

[0023] The connecting bolt is mounted on the connecting cylinder, and the end of the connecting bolt presses the follower rod against the inside of the connecting cylinder.

[0024] Optionally, the power source for rotating the locking disc includes a rotating gear ring and a rotating motor, wherein:

[0025] The rotating gear ring is coaxially mounted on the outer circumferential surface of the locking disc;

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Through automated control, the linear movement and rotation of the locking disc achieve mold locking and mold parting. During mold locking, the linear power source of the locking disc first drives the locking disc closer to the connecting body, causing the locking block on the connecting body to insert into the notch between the locking disc's stops. Subsequently, the rotational power source of the locking disc drives the locking disc to rotate through the meshing of the rack and pinion, causing the stop to limit the locking block, thus completing mold locking. Mold parting is the reverse operation. In this process, the follower rod plays a crucial positioning role. Its end away from the locking disc is placed inside the linear limiting groove, slidingly engaging with the groove wall to ensure that the rotating pinion on the locking disc remains in the same position when establishing or disengaging with the rack. This avoids collisions caused by misalignment of the rotating pinion and rack, ensuring accurate engagement of the locking block and stop between the locking disc and the connecting body, thereby improving the accuracy and reliability of mold locking and parting operations.

[0034] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0035] This application discloses a mold-locking device for an underwater pelletizer.

[0036] Example 1

[0037] A locking device for an underwater pelletizer includes a connector 1, a locking disc 2, a locking disc position monitoring component 3, and a processor. The connector 1 is mounted on the water chamber and has multiple locking blocks 11 circumferentially arranged along its own axis. The locking disc 2 is mounted on the pelletizing device of the underwater pelletizer and is in a sealed rotational fit with the pelletizing device. The locking disc 2 has multiple stops 21 circumferentially arranged along its own axis, and a notch for the locking blocks 11 to be inserted is formed between two adjacent stops 21.

[0038] The locking disc 2 moves closer to or further away from the connecting body 1 along a predetermined path via a linear power source and rotates around its own axis via a rotary power source 4. The linear power source, rotary power source 4, and position monitoring component 3 are all electrically connected to the processor.

[0039] When mold locking is required, the linear power source of the locking disc drives the locking disc 2 to move towards the connecting body 1, causing the locking block 11 to insert into the notch between two adjacent stop blocks 21. Then, the rotational power source of the locking disc 4 drives the locking disc 2 to rotate, causing the stop blocks 21 to limit the locking block 11, thus completing the mold locking. When mold separation is required, the reverse steps are followed. Both mold locking and mold separation are automated, thereby improving the convenience of mold locking and mold separation.

[0040] During the linear movement of the locking disc 2, the position of the locking disc 2 is located in real time by the locking disc position monitoring component 3 and the processor. When the locking disc 2 reaches the set position, the processor controls the locking disc 2 to stop moving in the linear direction and rotates the locking disc 2 so that the stop block 21 limits the locking block 11.

[0041] In this embodiment, a conveying platform is provided below the locking disc 2, the pelletizing device is installed on the conveying platform and slides with the conveying platform, the locking disc 2 is sealed on the pelletizing device and rotates with the pelletizing device, and the linear power source of the locking disc drives the pelletizing device to move on the conveying platform to drive the locking disc 2 to move.

[0042] The locking disc rotation power source 4 includes a rotating gear ring 41 and a rack 42. The rotating gear ring 41 is coaxially mounted on the outer circumferential surface of the locking disc 2. The length direction of the rack 42 is perpendicular to the axial direction of the rotating gear ring 41. The rack 42 moves along the length direction of the rack 42 through the rack power source 3 and meshes with the rotating gear ring 41.

[0043] When it is necessary to rotate the locking disc 2, the rack 42 is driven to move along its own length direction by the rack power source 3. During the movement of the rack 42, the rack 42 drives the locking disc 2 to rotate by rotating the gear ring 41.

[0044] A mounting platform is located near the rack 42, and the rack 42 and the mounting platform are slidably engaged along the length of the rack 42 via a guide seat 5. In this embodiment, the conveying platform and the mounting platform are integrally formed.

[0045] In this embodiment, the rack power source 3 is a cylinder. The cylinder is fixed at the bottom of the mounting platform near the rack 42, and the length direction of the cylinder is consistent with the length direction of the rack 42. The end of the cylinder push rod and the end of the rack 42 are detachably and fixedly connected by a connecting plate.

[0046] Since the rack 42 and the connecting plate are detachably and fixedly connected, it is convenient to adjust the initial position of the rack 42 before connecting the rack 42 to the connecting plate. This connection method is more convenient than adjusting the initial position of the rack 42 by a cylinder.

[0047] Meanwhile, in this embodiment, in order to facilitate the replacement of the rotating gear ring 41, the rotating gear ring 41 and the locking disc 2 are detachably and fixedly connected, thereby facilitating the timely replacement of severely worn or damaged rotating gear ring 41 and extending the life of the locking disc rotation power source 4.

[0048] The guide seat 5 is mounted on the installation platform. In this embodiment, the guide seat 5 and the installation platform are detachably and fixedly connected so that the position of the guide seat 5 can be adjusted according to the installation needs.

[0049] The guide seat 5 is generally arranged in a U-shape, and the opening of the guide seat 5 faces the rotating gear ring 41. The rack 42 is partially placed inside the guide seat 5 and slides with the guide seat 5. The inner wall of the guide seat 5 is provided with multiple anti-friction protrusions 51 on the side near the rack 42, and the rack 42 contacts the anti-friction protrusions 51.

[0050] The length direction of each anti-friction protrusion 51 is consistent with the length direction of the rack 42, and several anti-friction protrusions 51 are distributed along the width direction of the rack 42. The cross-sectional area of ​​each anti-friction protrusion 51 decreases from the direction away from the rack 42 to the direction closer to the rack 42.

[0051] In this embodiment, the anti-friction protrusion 51 has a semi-circular longitudinal section, and there is line contact between the rack 42 and the anti-friction protrusion 51. The small contact area between the anti-friction protrusion 51 and the rack 42 facilitates grinding of the contact portion between them.

[0052] The locking disc position monitoring component 3 includes a follower rod 31 and a distance monitoring sensor 32.

[0053] One end of the follower rod 31 is mounted on the locking plate 2. In order to facilitate the replacement of the follower rod 31, the locking plate 2 and the follower rod 31 are detachably connected by the connector 8, which includes a connecting cylinder 81 and a connecting bolt 82.

[0054] One end of the connecting cylinder 81 is fixedly mounted on the locking plate 2, and the end of the follower rod 31 near the locking plate 2 is inserted into the connecting cylinder 81. The connecting bolt 82 passes through the side wall of the connecting cylinder 81 and is threadedly connected to the connecting cylinder 81. The end of the connecting bolt 82 presses the inner connecting cylinder 81 against the inner wall of the connecting cylinder 81.

[0055] A linear limiting groove 6 is provided on the side of the conveying platform near the locking plate 2 along the axis of the locking plate 2. A rotary guide groove 7 is provided on the inner wall of the linear limiting groove 6. The end of the follower rod 31 away from the locking plate 2 is placed inside the linear limiting groove 6, which slides with the linear limiting groove 6 and rotates with the rotary guide groove 7.

[0056] The distance monitoring sensor 32 is located on the conveying platform near the linear limiting groove 6. In this embodiment, the distance monitoring sensor 32 is an infrared ranging sensor, which is electrically connected to the processor.

[0057] When the locking disc 2 moves, the locking disc 2 drives the follower rod 31 to move inside the linear limiting groove 6. During the movement of the follower rod 31, the position of the follower rod 31 is located by the distance monitoring sensor 32 and the processor. After the position of the follower rod 31 reaches the set value, the locking disc 2 is controlled to rotate.

[0058] When the locking disc 2 moves in a straight line, the end of the follower rod 31 away from the locking disc 2 is always placed inside the straight limiting groove 6. The inner wall of the straight limiting groove 6 is positioned by the follower rod 31 on the rotating gear ring 41 on the locking disc 2, so that the rotating gear ring 41 and the rack 42 are always in the same position when establishing the meshing connection and when disengaging the meshing connection.

[0059] This facilitates repeated engagement of the rotating gear ring 41 and rack 42 on the locking disc 2, reducing the possibility of the rotating gear ring 41 and rack 42 colliding when the locking disc 2 moves towards the connecting body 1 due to accidental rotation of the locking disc 2, misalignment of the rotating gear ring 41 and rack 42.

[0060] The implementation principle of the mold-locking device for an underwater pelletizer in Embodiment 1 of this application is as follows: Through automated control, the linear movement and rotation of the locking disc 2 realize mold locking and mold separation. During the mold locking process, the linear power source of the locking disc first drives the locking disc 2 to approach the connecting body 1, so that the locking block 11 on the connecting body 1 is inserted into the notch between the stop blocks 21 of the locking disc 2. Subsequently, the rotational power source 4 of the locking disc drives the locking disc 2 to rotate through the meshing of the rack 42 and the rotating gear ring 41, so that the stop block 21 limits the locking block 11, completing the mold locking. Mold separation is the reverse operation. During this process, the follower rod 31 plays a crucial positioning role. Its end away from the locking disc 2 is placed inside the linear limiting groove 6 and slides with the groove wall to ensure that the rotating gear ring 41 on the locking disc 2 is always in the same position when it engages or disengages with the rack 42. This avoids collisions caused by misalignment of the rotating gear ring 41 and the rack 42, and ensures accurate engagement between the locking disc 2 and the connecting body 1, as well as the locking block 11 and the stop block 21. This improves the accuracy and reliability of the mold locking and mold splitting operations.

[0061] Example 2

[0062] The difference between this embodiment and Embodiment 1 is that the locking disc rotation power source 4 includes a rotating gear ring 41 and a rotating motor. The rotating gear ring 41 is coaxially fixedly installed on the outer circumferential surface of the locking disc 2, and the rotating motor is fixedly installed on the pelletizing device. The motor shaft of the rotating motor is provided with drive teeth that mesh with the rotating gear ring 41.

[0063] The implementation principle of Example 2 is as follows: when it is necessary to rotate the locking disc 2, the rotary motor drives the locking disc 2 to rotate by meshing the drive teeth and the rotating gear ring 41.

[0064] 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.
