Adjustable gap double roller press structure

Abstract

This utility model discloses an adjustable-gap double-roll press structure, including a base and side plates. The side plates are fixedly installed on the top surface of the base, and the surface of the side plates is provided with sliding grooves. Beneficial effects: This utility model uses a sliding block and a third synchronous wheel. When adjusting the gap between the fixed and moving rollers, a servo motor can be started to drive the lead screw to rotate, which in turn drives the sliding block to move along the sliding groove. When the sliding block moves to the left, the electric cylinder extends synchronously, pushing the third synchronous wheel upward to maintain the tension of the synchronous belt. The fixed roller rotates under the drive device, driving the driven gear to rotate through the drive gear, which in turn drives the side shaft and the first synchronous wheel to rotate, driving the synchronous belt to rotate, driving the second synchronous wheel to rotate, and driving the moving roller to rotate. Operators can easily adjust the gap between the moving and fixed rollers by adjusting the servo motor and the electric cylinder, avoiding the problem of a small adjustment range caused by bevel gear connections, expanding the adjustment range, and improving adjustment efficiency.

Description

Technical Field

[0001] This utility model relates to the field of two-roll open mill technology, and more specifically, to an adjustable-pitch two-roll press structure. Background Technology

[0002] A two-roll mill uses two rollers rotating in opposite directions to compress and refine rubber. The distance between the two rollers needs to be adjusted during the refining process for different types of rubber to achieve better refining results and efficiency.

[0003] After searching, it was found that application number CN202020526616.3, entitled "A Roller Structure for an Adjustable Gap Two-Roll Open Mill," addresses the problem that adjusting the roller gap of existing two-roll open mills is cumbersome and requires disassembly. The method involves rotating a rotating rod to move a slider and a driven roller connected to the slider along a guide rail, thereby adjusting the gap between the driven and driven rollers. The driven and driven rollers are connected by bevel gears and fixed by a compression spring. However, the bevel gears have a limited outer diameter, which means the adjustment range must meet the meshing range of the bevel gears, resulting in a very small adjustment range and low efficiency. Furthermore, the springs have elasticity and are prone to deformation under stress, making it difficult to maintain overall stability. Further improvements are possible.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] To achieve the advantages of a wide adjustment range and stable and reliable operation, the specific technical solution adopted by this utility model is as follows: An adjustable-gap double-roll press structure includes a base and side plates. The side plates are fixedly mounted on the top surface of the base, and a sliding groove is formed on the surface of the side plates. A sliding block is slidably connected inside the groove. A movable roller is rotatably connected between the sliding blocks, and the movable roller is rotatably connected to the sliding block via a roller shaft. Second synchronous pulleys are fixedly connected to both ends of the roller shaft of the movable roller. A fixed roller is rotatably connected between the side plates, and the fixed roller is rotatably connected to the side plates via a roller shaft. A drive gear is fixedly connected to one end of the roller shaft of the fixed roller. A side shaft is rotatably connected to the outer wall of the side plates, and the surface of the side shaft is fixed... A driven gear is fitted onto the outer side of the driven gear, and the driven gear meshes with the drive gear. A first synchronous pulley is fixedly fitted onto the outer wall of the side shaft on the outer side of the driven gear. An electric cylinder is fixedly installed on the top surface of the base on the outer side of the side plate, and a wheel frame is fixedly installed on the top surface of the moving rod of the electric cylinder. A third synchronous pulley is rotatably connected between the wheel frames. A synchronous belt is fitted onto the surfaces of the third synchronous pulley, the first synchronous pulley, and the second synchronous pulley. A servo motor is fixedly installed at one end of the side plate, and a lead screw is installed at the output end of the servo motor. The lead screw passes through the slide and is threadedly connected to the slide.

[0007] Furthermore, one end of the lead screw is rotatably connected to the side plate via a bearing, and the other end of the lead screw is rotatably connected to the inner wall of the slide groove via a rotating connecting seat.

[0008] Furthermore, a guide rod is fixedly installed inside the slide groove, and the guide rod passes through the slide block and is slidably connected to the slide block.

[0009] Furthermore, the moving roller and the fixed roller are the same size, and the moving roller and the fixed roller are installed at the same height.

[0010] Furthermore, two sets of side shafts are arranged, and the side shafts are rotatably connected to the outer wall of the side plate through a rotating connecting seat.

[0011] Furthermore, the first synchronous pulley, the second synchronous pulley, the third synchronous pulley, and the synchronous belt are each arranged in two sets.

[0013] Furthermore, the roller shaft of the fixed roller is rotatably connected to the side plate via bearings.

[0014] Compared with the prior art, this utility model provides an adjustable-gap double-roll press structure, which has the following beneficial effects: (1) This utility model adopts a sliding block and a third synchronous wheel. When adjusting the gap between the fixed roller and the moving roller, the servo motor can be started to drive the lead screw to rotate, which in turn drives the sliding block to move along the slide groove. When the sliding block moves to the left, the electric cylinder extends synchronously, pushing the third synchronous wheel to move up, maintaining the tension of the synchronous belt. The fixed roller rotates under the drive device, and drives the driven gear to rotate through the drive gear, which in turn drives the side shaft and the first synchronous wheel to rotate, drives the synchronous belt to rotate, drives the second synchronous wheel to rotate, and drives the moving roller to rotate. The operator can easily adjust the gap between the moving roller and the fixed roller by adjusting the servo motor and the electric cylinder, and avoids the problem of small adjustment range caused by bevel gear connection, expands the adjustment range, and improves the adjustment efficiency.

[0015] (2) This utility model uses an electric cylinder and a guide rod. After the electric cylinder extends and retracts, it forms a self-locking mechanism, which avoids the random movement of the third synchronous wheel and improves the stability after adjustment. At the same time, the guide rod is the moving guide of the slide block, which improves the stability of adjustment. The lead screw is stationary when the servo motor stops running, which further improves the stability of the moving roller and thus improves the overall working stability.

[0020] According to an embodiment of the present invention, an adjustable-pitch double-roll press structure is provided.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, the adjustable-gap double-roll press structure according to an embodiment of the present invention includes a base 1 and side plates 2. Side plates 2 are fixedly installed on the top surface of the base 1. Two sets of side plates 2 are arranged, and a sliding groove 3 is formed on the surface of the side plates 2. A sliding seat 4 is slidably connected inside the sliding groove 3. A movable roller 5 is rotatably connected between the sliding seats 4, and the movable roller 5 is rotatably connected to the sliding seat 4 via a roller shaft. Second synchronous pulleys 11 are fixedly connected to both ends of the roller shaft of the movable roller 5. A fixed roller 6 is rotatably connected between the side plates 2, and the fixed roller 6 is rotatably connected to the side plates 2 via a roller shaft. The system is dynamically connected, and a drive gear 7 is fixedly connected to one end of the roller shaft of the fixed roller 6. A side shaft 8 is rotatably connected to the outer wall of the side plate 2, and a driven gear 10 is fixedly sleeved on the surface of the side shaft 8. The driven gear 10 meshes with the drive gear 7. A first synchronous wheel 9 is fixedly sleeved on the outer side of the driven gear 10 on the outer wall of the side shaft 8. An electric cylinder 15 is fixedly installed on the top surface of the base 1 on the outer side of the side plate 2, and a wheel frame 16 is fixedly installed on the top surface of the moving rod of the electric cylinder 15. A third synchronous wheel 17 is rotatably connected between the wheel frames 16. Synchronous belts 18 are fitted onto the surfaces of wheel 17, first synchronous wheel 9, and second synchronous wheel 11. A servo motor 14 is fixedly mounted on one end of the side plate 2, and a lead screw 12 is mounted on the output end of the servo motor 14. The lead screw 12 passes through the slide block 4 and is threadedly connected to the slide block 4. When adjusting the gap between the fixed roller 6 and the moving roller 5, the servo motor 14 can be started to drive the lead screw 12 to rotate, thereby driving the slide block 4 to move along the slide groove 3. When the slide block 4 moves to the left, the electric cylinder 15 extends synchronously, pushing the third synchronous wheel 17 to move upward, maintaining the tension of the synchronous belt 18. The fixed roller 6 rotates under the drive device, driving the driven gear 10 to rotate through the drive gear 7, thereby driving the side shaft 8 and the first synchronous wheel 9 to rotate, driving the synchronous belt 18 to rotate, driving the second synchronous wheel 11 to rotate, and driving the moving roller 5 to rotate. The operator can easily adjust the gap between the moving roller 5 and the fixed roller 6 by adjusting the servo motor 14 and the electric cylinder 15, and avoids the problem of small adjustment range caused by bevel gear connection, thus expanding the adjustment range and improving the adjustment efficiency.

[0022] In one embodiment, one end of the lead screw 12 is rotatably connected to the side plate 2 via a bearing, and the other end of the lead screw 12 is rotatably connected to the inner wall of the slide groove 3 via a rotating connecting seat. After the electric cylinder 15 extends and retracts, it forms a self-locking mechanism, which prevents the third synchronous wheel 17 from moving arbitrarily and improves the stability after adjustment. At the same time, the guide rod 13 serves as the moving guide for the slide block 4, which improves the stability of adjustment. The lead screw 12 is stationary when the servo motor 14 stops running, which further improves the stability of the moving roller 5 and thus improves the overall working stability.

[0023] In one embodiment, a guide rod 13 is fixedly installed inside the slide 3, and the guide rod 13 passes through the slide 4 and is slidably connected to the slide 4 to improve the stability of the slide 4 movement.

[0024] In one embodiment, the moving roller 5 and the fixed roller 6 are the same size and have the same installation height, which is a common structure in the art.

[0025] In one embodiment, two sets of side shafts 8 are arranged, and the side shafts 8 are rotatably connected to the outer wall of the side plate 2 through a rotary connecting seat, which is a common rotary connection form.

[0026] In one embodiment, two sets of the first synchronous pulley 9, the second synchronous pulley 11, the third synchronous pulley 17, and the synchronous belt 18 are arranged to achieve synchronous rotation of both ends of the moving roller 5 and the fixed roller 6.

[0027] In one embodiment, the roller shaft of the moving roller 5 is rotatably connected to the slide block 4 via a bearing, and two sets of slide blocks 4 are arranged to improve the stability of the movement of the moving roller 5.

[0028] In one embodiment, the roller shaft of the fixed roller 6 is rotatably connected to the side plate 2 via a bearing, thereby improving the stability of the rotation of the fixed roller 6.

[0029] Working principle: When adjusting the gap between the fixed roller 6 and the moving roller 5, the servo motor 14 can be started to drive the lead screw 12 to rotate, which in turn drives the slide block 4 to move along the slide groove 3. When the slide block 4 moves to the left, the electric cylinder 15 extends synchronously, pushing the third synchronous pulley 17 to move upward, maintaining the tension of the synchronous belt 18. The fixed roller 6 rotates under the drive device, driving the driven gear 10 to rotate through the drive gear 7, which in turn drives the side shaft 8 and the first synchronous pulley 9 to rotate, driving the synchronous belt 18 to rotate, driving the second synchronous pulley 11 to rotate, and driving the moving roller 5 to rotate. The operator can easily adjust the servo motor 14 to rotate the roller 5. The machine 14 and the electric cylinder 15 complete the adjustment of the gap between the moving roller 5 and the fixed roller 6, and avoid the problem of small adjustment range caused by bevel gear connection, thus expanding the adjustment range and improving the adjustment efficiency. At the same time, the electric cylinder 15 forms a self-locking mechanism after extension and retraction, preventing the third synchronous wheel 17 from moving arbitrarily and improving the stability after adjustment. Meanwhile, the guide rod 13 serves as the moving guide for the slide 4, improving the stability of adjustment. The lead screw 12 is stationary when the servo motor 14 stops running, further improving the stability of the moving roller 5, and thus improving the overall working stability.
