Description

Technical Field

[0001] This utility model belongs to the field of crusher technology, and in particular relates to a gap adjustment mechanism in a crusher. Background Technology

[0002] Crushing is a crucial step in feed processing, and its effectiveness directly impacts feed quality. Pelletizers, a commonly used crushing equipment, often suffer from inconsistent roller gaps after adjusting the left and right roller clearances. This affects feed quality, production efficiency, and worker workload. Ordinary crushing equipment struggles to maintain consistent roller gaps when adjusting the opening of the fast and slow rollers during the production of different finished products, requiring highly skilled workers and severely impacting production efficiency, ultimately affecting the company's competitiveness. Utility Model Content

[0003] In order to solve the technical problem of inconvenience in manually adjusting the opening of the fast and slow rollers in the background art, the purpose of this utility model is to provide an adjusting mechanism in a crusher that can solve the above-mentioned problems.

[0004] The technical solution to achieve the purpose of this utility model is: a gap adjustment mechanism in a crusher, including a left gap adjustment mechanism and a right gap adjustment mechanism that are arranged opposite to each other and have the same structure. The left gap adjustment mechanism includes a fixed plate, a rotating plate and a telescopic mechanism. The rotating plate is rotatably mounted on the frame, and the telescopic mechanism is fixedly mounted on the fixed plate. The telescopic mechanism has a telescopic shaft, which is mounted on the rotating plate and is used to drive the rotating plate to rotate along one side of the fixed plate. The rotating plate has mounting holes for mounting rollers.

[0005] To address the issues of inconsistent left and right clearance and roller gaps in this crusher, this solution employs a novel automatic adjustment mechanism. Specifically, it includes a left and right adjustment mechanism with identical structures, positioned opposite each other. The roller shaft requiring adjustment is mounted on a rotating plate. As the telescopic shaft of the telescopic conveyor extends and retracts, it drives the rotating plate to rotate along one side of the fixed plate, thus adjusting the position of the roller requiring adjustment. Since the adjustment is performed by the telescopic shaft of the telescopic conveyor, the adjustment distance can be controlled by the system, resulting in a high degree of automation. This replaces traditional manual adjustment, solving various problems associated with manual adjustment. This solution's adjustment mechanism offers high automation, precise adjustment, and high efficiency, significantly improving enterprise efficiency and competitive advantage. The rotating plate can be mounted on the frame in various ways, such as by having a rotating hole on the frame and a corresponding rotating shaft on the rotating plate, with the shaft rotatably mounted within the rotating hole.

[0006] Furthermore, it also includes a rotating seat mounted on the rotating plate. The rotating seat has a first through hole, and the telescopic shaft is installed in the first through hole. The telescopic machine drives the rotating plate to rotate along one side of the fixed plate through the cooperation of the telescopic shaft and the rotating seat. The diameter of the first through hole is larger than the outer diameter of the telescopic shaft, allowing for clearance adjustment within the first through hole during the telescopic movement of the telescopic shaft. Simultaneously, the end of the telescopic shaft can be secured with a locking nut, thus confining the telescopic shaft within the first through hole and preventing it from disengaging from the rotating seat when retracting towards the telescopic machine body.

[0007] Furthermore, the rotating base includes a rotating frame and a rotating block. The rotating frame has a mounting cavity, and the rotating block is rotatably mounted within the mounting cavity. The rotating block has a second through hole corresponding to the first through hole, and the telescopic shaft passes through both the first and second through holes. Since the rotating plate rotates on the fixed plate under the drive of the telescopic shaft, a change in vertical displacement angle occurs during rotation. Therefore, a rotating block is added. The telescopic shaft passes through the second through hole on the rotating block, and the rotating block can be rotated and adjusted within the mounting cavity to release the required vertical displacement and angle changes. The rotating block can be spherical or square, etc., as long as it can rotate within the mounting cavity.

[0008] Furthermore, the rotating block has mounting protrusions, and the rotating frame has mounting grooves. The mounting protrusions are installed within the mounting grooves, and the gap in the mounting grooves is larger than that of the mounting protrusions. To prevent the rotating block from rotating randomly within the mounting cavity and to address installation issues, the mounting protrusions, resembling wing shapes, can be installed on opposite sides of the rotating block before being installed into the mounting grooves. This allows for rotation while restricting the rotational displacement of the rotating block.

[0009] Furthermore, a spring is installed between the rotating seat and the telescopic machine body, and the spring is sleeved on the telescopic shaft. When the roller mounted on the rotating plate is subjected to force, the telescopic shaft remains stationary, and the rotating plate and rotating seat are pressed towards the telescopic machine body. The spring is compressed under force, which plays a buffering and protective role during the compression process.

[0010] Furthermore, it also includes a limiting mechanism, which is mounted on the fixed plate and corresponds to the telescopic shaft. The limiting mechanism is used to limit the travel range of the telescopic shaft, protect the overall adjustment mechanism, and prevent damage to the device when the travel is too large.

[0011] Furthermore, the limiting mechanism includes a limit switch base, which is fixed to the fixed plate. Two opposing limit switches are mounted on the limit switch base, and a travel baffle is installed at the end of the telescopic shaft, moving between the two limit switches. To better limit the telescopic shaft, two opposing limit switches are used, with the travel baffle at the end of the telescopic shaft located between the two limit switches. When the travel reaches its maximum or minimum value, the limit switch will be triggered, allowing for timely power-off protection or emergency handling.

[0012] Furthermore, a connecting rod is installed between the telescopic mechanisms of the left and right adjustment mechanisms via a coupling, which facilitates the synchronous start-up and operation of the two telescopic mechanisms, and the adjustment of the gap on the left and right sides is carried out synchronously.

[0013] Furthermore, a geared motor is also installed on the right adjusting mechanism to drive the telescopic mechanism on both the left and right adjusting mechanisms to move synchronously. A single geared motor can drive both adjusting mechanisms, reducing costs.

[0014] Furthermore, an encoder is connected to one side of the telescopic machine to monitor the telescopic distance of the telescopic shaft in real time. The numerical range of the gap can be monitored and reflected in real time through the encoder, making the overall control more intelligent and controllable.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] (1) A left gap adjustment mechanism and a right gap adjustment mechanism are respectively set at both ends of the crusher, including a rotating plate that rotates on a fixed plate and a telescopic mechanism that drives the rotating plate to rotate. The telescopic shaft of the telescopic mechanism drives the rotating plate to rotate during the telescopic movement. Rollers are installed on the rotating plate, thereby realizing the problem of mechanized automatic adjustment of the gap between the fast and slow rollers.

[0017] (2) Further, a rotating frame and a rotating block are added to the rotating structure to solve the problems of vertical displacement and angle change caused by the telescopic shaft driving the rotating plate to rotate during the telescopic movement;

[0018] (3) A spring is installed between the rotating seat and the telescopic machine body. When the telescopic shaft needs to extend outward, the spring will be compressed and then rebound to its natural state.

[0019] (4) Add a limit mechanism consisting of two limit switches to effectively limit and protect the travel of the telescopic shaft. Attached Figure Description

Detailed Implementation

[0028] Example:

[0029] like Figures 1-2As shown, this embodiment provides a gap adjustment mechanism in a crusher, including a left gap adjustment mechanism 1 and a right gap adjustment mechanism 2 that are arranged opposite to each other and have the same structure. The left gap adjustment mechanism 1 includes a fixed plate 3, a rotating plate 4, and a telescopic mechanism 5. The rotating plate 4 is rotatably mounted on the frame, and the telescopic mechanism 5 is fixedly mounted on the fixed plate 3. The telescopic mechanism 5 has a telescopic shaft 6, which is mounted on the rotating plate 4 and used to drive the rotating plate 4 to rotate along one side of the fixed plate 3. The rotating plate 4 has mounting holes 25 for mounting rollers. To solve the problem of inconsistent gap adjustment and roller gap in the crusher, this solution uses a brand-new gap adjustment mechanism for automatic adjustment. Specifically, it includes a left gap adjustment mechanism 1 and a right gap adjustment mechanism 2 that are arranged opposite to each other and have the same structure. The rollers of the rollers whose positions need to be adjusted are mounted on the rotating plate 4. Then, when the telescopic shaft 6 of the telescopic mechanism 5 extends and retracts, it drives the rotating plate 4 to rotate along one side of the fixed plate 3, which means it can drive the rollers whose positions need to be adjusted to adjust their positions. Since the adjustment is achieved through the telescopic movement of the telescopic shaft 6 of the telescopic machine 5, the adjustment distance can be controlled by the system, resulting in a high degree of automation. This replaces traditional manual adjustment, solving various problems arising from manual adjustment. The adjustment mechanism of this solution has a high degree of automation, precise adjustment, and high efficiency, which can greatly improve the company's efficiency and competitive advantage. The rotating plate 4 can be mounted on the frame in many ways, such as having a rotating hole on the frame and a corresponding rotating shaft 24 on the rotating plate 4, with the rotating shaft 24 rotatably mounted within the rotating hole.

[0030] Preferably, a connecting rod 20 is installed between the telescopic mechanisms 5 of the left adjusting mechanism 1 and the right adjusting mechanism 2 via a coupling 21, facilitating synchronous start-up and operation of the two telescopic mechanisms 5, and simultaneous adjustment of the clearance on both sides. A geared motor 22 is also installed on the right adjusting mechanism 2 to drive the telescopic mechanisms 5 on the left adjusting mechanism 1 and the right adjusting mechanism 2 to move synchronously. A single geared motor can drive both adjusting mechanisms, reducing costs.

[0031] Preferably, an encoder 23 is also connected to one side of the telescopic machine 5 to monitor the telescopic distance of the telescopic shaft 6 in real time. The numerical range of the gap can be monitored and reflected in real time through the encoder 23, making the overall control more intelligent and controllable.

[0032] like Figures 3-5As shown, it also includes a rotating seat 7, which is mounted on the rotating plate 4. The rotating seat 7 has a first through hole 8, and the telescopic shaft 6 is installed in the first through hole 8. The telescopic machine 5 drives the rotating plate 4 to rotate along one side of the fixed plate 3 through the cooperation of the telescopic shaft 6 and the rotating seat 7. The diameter of the first through hole 8 is larger than the outer diameter of the telescopic shaft 6, and the gap can be adjusted within the first through hole 8 during the telescopic movement of the telescopic shaft 6. At the same time, a locking nut can be tightened at the end of the telescopic shaft 6, so that the telescopic shaft 6 is restricted within the first through hole 8 and will not disengage from the rotating seat 7 when retracting towards the telescopic machine body 15. The rotating seat 7 includes a rotating frame 9 and a rotating block 10, and the rotating frame 9 has a mounting cavity.

[0033] 11. The rotating block 10 is rotatably installed within the mounting cavity. The rotating block 10 has a second through hole 12 corresponding to the first through hole 8, and the telescopic shaft 6 passes through the first through hole 8 and the second through hole 12 respectively. Since the rotating plate 4 rotates on the fixed plate 3 under the drive of the telescopic shaft 6, a change in vertical displacement angle will occur during rotation. Therefore, the rotating block 10 is added. The telescopic shaft 6 passes through the second through hole 12 on the rotating block 10, and the rotating block 10 can be rotated and adjusted within the mounting cavity 11 to release the required vertical displacement and angle changes. The rotating block 10 can be spherical or square, etc., as long as it can rotate within the mounting cavity 11. The rotating block 10 has a mounting protrusion 13, and the rotating frame 9 has a mounting groove.

[0034] 14. The mounting protrusion 13 is installed in the mounting groove 14, and the gap of the mounting groove 14 is larger than that of the mounting protrusion 13. In order to prevent the rotating block 10 from rotating randomly in the mounting cavity 11 and to solve the installation problem of the rotating block 10, the mounting protrusion 13, which is similar to a wing shape, can be installed on opposite sides of the rotating block 10, and then installed into the mounting groove 14. This allows for rotation while restricting the rotational displacement of the rotating block 10.

[0035] Preferably, a spring 16 is installed between the rotating seat 7 and the telescopic machine body 15, and the spring 16 is sleeved on the telescopic shaft 6. When the roller installed on the rotating plate 4 is subjected to force, the telescopic shaft 6 remains stationary, and the rotating plate 4 and the rotating seat 7 are pressed towards the telescopic machine body 15. The spring 16 is compressed under force, and plays a buffering and protective role during the compression process.

[0036] like Figure 6As shown, it also includes a limiting mechanism, which is mounted on the fixed plate 3 and corresponds to the telescopic shaft 6. This limiting mechanism limits the travel range of the telescopic shaft 6, protecting the overall adjusting mechanism and preventing damage to the device from excessive travel. The limiting mechanism includes a limit switch base 17, which is fixed to the fixed plate 3. Two oppositely arranged limit switches are mounted on the limit switch base 17.

[0037] 18. A travel baffle 19 is installed at the end of the telescopic shaft 6, and the travel baffle 19 moves between the two limit switches 18. In order to better limit the telescopic shaft 6, two limit switches 18 are arranged opposite to each other, and the travel baffle 19 installed at the end of the telescopic shaft 6 is located between the two limit switches 18. When the travel is at its maximum or minimum value, it will touch the limit switch 18, which can promptly perform power-off protection or emergency handling.

[0038] Working principle: After the telescopic conveyor 5 is started, the telescopic shaft 6 extends and retracts, driving the rotating seat 7 and rotating plate 4 to rotate. The rollers in the crusher are installed in the mounting holes 25. After the rotating plate 4 rotates, it will drive the rollers to move, thereby adjusting the gap between the fast and slow rollers. The rotating block 10 in the rotating seat 7 is rotatably installed in the rotating frame 9 to eliminate problems such as vertical displacement and angle changes. The stroke baffle 19 installed at the end of the telescopic shaft 6 moves within the two limit switches 18, which serves to limit the stroke.

[0039] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
