Description

Technical Field

[0001] The utility model relates to the technical field of pinch rollers, in particular to a pinch roller guide device. Background Art

[0002] A pinch roller guide is a component of equipment used in industrial production. Its primary function is to effectively clamp, convey, and guide materials or workpieces on the production line. This device typically includes a clamping roller or clamping mechanism that precisely grasps and secures the workpiece, ensuring its stability and accurate positioning during conveyance. Furthermore, the guide is meticulously designed to accurately guide the workpiece, preventing deviation or disorganization, thereby ensuring the continuity and efficiency of the production line. This device is designed to address the issues of low production efficiency and inconsistent product quality caused by unstable workpiece movement or misaligned workpiece alignment in traditional operations, thereby improving the automation level and overall operational efficiency of the production line.

[0003] A search revealed a Chinese patent with publication number CN216369536U, which discloses a highly efficient pinch roller device for rebar production. The patent describes a device that incorporates an auxiliary correction device in the middle of the top of the machine body, and a drive mechanism installed at the bottom of the housing. The drive mechanism drives a movable plate through a connecting rod to move a push rod, which in turn drives an anti-slip mechanism to correct the lower pressure roller, preventing it from shifting over time. The device is easy to use and operate, effectively improving the efficiency of advanced preparation and processing of high-performance steel.

[0004] In this solution, although the problem of the lower pressure roller being offset after long-term use is solved, when the material is placed between the upper pressure roller and the lower pressure roller, it cannot be guaranteed that the material conveying direction will always remain consistent. If the material is offset during transportation, it will cause blockage and accumulation in the subsequent processing equipment, thereby reducing the work efficiency of the production line. In order to solve this technical problem, the utility model proposes a pinch roller guide device. Summary of the Invention

[0014] (3) Beneficial effects

[0015] The utility model provides a pinch roller guide device with the following beneficial effects:

[0016] (1) The one-way threaded rod is driven to rotate by starting the second motor. When the one-way threaded rod rotates, it drives the bevel gear 2 at the bottom to rotate. Under the rotation of the bevel gear 2, it drives the meshing bevel gear 1 to rotate, and drives the internal two-way threaded rod to rotate.

[0017] (2) The one-way threaded rod on the fixed plate is driven to rotate by starting the second motor. When the one-way threaded rod rotates, the connecting frame on the outer wall is driven to move up and down. The up and down movement of the connecting frame can drive the upper pressure roller on the inner rod to adjust up and down, thereby ensuring that the distance between the upper pressure roller and the lower pressure roller corresponds to the material. When the upper pressure roller is adjusted up and down, the connecting frame on the other side is limited on the positioning rod at the same time, so that the moving direction of the upper pressure roller remains consistent. Through the cooperation between them, rapid adjustment according to different material sizes is achieved, solving the problem that traditional equipment cannot be adjusted, and improving work efficiency.

The bracket 6 plays the role of supporting the positioning mechanism. A positioning mechanism 10 is fixedly connected below the bracket 6. The positioning mechanism 10 includes a bidirectional threaded rod 1002, a pair of connecting blocks 1003 and a pair of clamping plates 1005. At the same time, the connecting block 1003 is threadedly connected to both ends of the bidirectional threaded rod 1002. When the bidirectional threaded rod rotates, it will drive the connecting blocks 1003 at both ends to move in the opposite direction. At the same time, the bidirectional threaded rod 1002 is rotatably connected to the bracket 6. The top of the connecting block 1003 is fixedly connected to a fixed block 1004, and the plate 1005 is fixedly connected It is connected to the inner wall of the fixed block 1004. When the connecting block 1003 moves, it will drive the splint 1005 clamped on the fixed block 1004 to move in the opposite direction, thereby achieving a clamping and positioning effect. Three rollers 1006 are arranged inside the splint 1005, and the rollers 1006 have a drag reduction effect. The outer walls of the connecting blocks 1003 on both sides are fixedly connected with sliders 1007, and the sliders 1007 are internally slidably connected to the limiting rod 1001. At the same time, the limiting rod 1001 is fixedly connected to the inner wall of the bracket 6, and the slider 1007 is limited on the limiting rod 1001, thereby ensuring that the moving direction of the splint 1005 on the fixed block 1004 remains consistent. Through their cooperation, the role of material positioning and guiding is achieved.

[0026] Embodiment 2: A first motor 3 is fixedly connected to one side of the base 2, and a rotating shaft 4 is fixedly connected to the output end of the first motor 3, and a lower pressure roller 5 is fixedly connected to the outer wall of the rotating shaft 4. A bracket 6 is fixedly connected to the outer wall of the base 2, and an adjustment mechanism 7 is provided above the bracket 6. The adjustment mechanism 7 includes a second motor 701, two pairs of fixed plates 702, a one-way threaded rod 703 and a pair of connecting frames 704. At the same time, the connecting frame 704 is threadedly connected to the outer wall of the one-way threaded rod 703, and the other end of the connecting frame 704 is rotatably connected to the inner rod 8. At the same time, the upper pressure roller 9 is fixedly connected to the outer wall of the inner rod 8, the one-way threaded rod 703 is fixedly connected to the output end of the second motor 701, and the one-way threaded rod Bevel gear 14 is fixedly connected to the bottom of 703. Bevel gear 11 is fixedly connected to the outer wall of one end of the bidirectional threaded rod 1002, and bevel gear 11 is meshed with bevel gear 14. The second motor 701 is fixedly connected to the outer wall of one side of the fixed plate 702. At the same time, the unidirectional threaded rod 703 is rotatably connected to the inside of the fixed plate 702. A positioning rod 705 is fixedly connected between the pair of fixed plates 702 on the other side. At the same time, the connecting frame 704 on the other side is slidably connected to the outer wall of the positioning rod 705. The top of the bracket 6 is fixedly connected to the electric hydraulic rod 12. The output end of the electric hydraulic rod 12 passes through the bracket 6 and is fixedly connected to the anti-slip plate 13. At the same time, the lower surface of the anti-slip plate 13 corresponds to the outer surface of the upper pressure roller 9. When the second motor 701 at the top of the fixed plate 702 is started, it drives the unidirectional threaded rod 703 to rotate within the fixed plate 702, causing the outer wall connecting frame 704 to move up and down. The movement of the connecting frame 704 adjusts the position of the upper pressure roller 9 on the outer wall of the inner rod 8. During its movement, the upper pressure roller 9 is restrained by the positioning rod 705 through the connecting frame 704 on the other side. Simultaneously, the first motor 3 is activated to rotate the upper pressure roller 5 on the rotating shaft 4. The combination of these two allows the device to accommodate the conveying of materials of varying sizes, thereby improving production efficiency. During material conveying, the bevel gear 2 11 at the bottom of the unidirectional threaded rod 703, driven by the second motor 701, rotates. This causes the meshing bevel gear 1 14 to rotate, which in turn drives the internal bidirectional threaded rod 1002 to rotate, ensuring accurate positioning of the material during conveying.

[0027] Working principle: The pinch roller guide device is usually an automated equipment used in industrial production lines, especially in conveyor belt systems. Its main function is to ensure the stability and accurate guidance of materials during the conveying process through a set of rollers and guiding devices, prevent the materials from deflecting or piling up, and thus ensure the smooth operation and safety of the production line. When the staff uses this device, they first adjust the distance between the lower pressure roller 5 and the upper pressure roller 9 according to the size of the material. At this time, the second motor 701 on the top of the fixed plate 702 is started. Under the action of the second motor 701, the one-way threaded rod 703 is driven to rotate inside the fixed plate 702. The rotation of the fixed plate 702 will drive the connecting frame 704 on the outer wall to move up and down. The connecting frame 704 will drive the upper pressure roller 9 on the outer wall of the inner rod 8 to adjust up and down. At the same time, the upper pressure roller 9 is limited to the positioning rod 705 on the other side of the connecting frame 704 during adjustment. Then the first motor 3 is started to drive the upper pressure roller 5 on the rotating shaft 4 to rotate. Through the cooperation between them, the conveying of materials of different sizes is achieved, which improves work efficiency. At the same time, when conveying materials, the direction of the materials needs to be positioned. When the second motor 701 is started, the one-way threaded rod 703 is rotated to drive the bevel gear at the bottom. The second bevel gear 11 rotates on its own, and the rotation of the bevel gear 11 drives the meshing bevel gear 14 to rotate, and the bevel gear 14 drives the internal two-way threaded rod 1002 to rotate. At this time, the rotation of the two-way threaded rod 1002 drives the connecting blocks 1003 at both ends to move left and right. At the same time, the movement of the connecting block 1003 corresponds to the up and down movement of the upper pressure roller 9. When the connecting block 1003 moves, it drives the splint 1005 on the fixed block 1004 to move, and the splint 1005 is used to position the material, and at the same time, the clamp The roller 1006 of the plate 1005 will reduce the friction, making the feeding smoother. When the connecting block 1003 moves, it will be limited on the limit rod 1001 through the connecting blocks 1003 on both sides, thereby ensuring that the moving direction of the splint 1005 remains consistent. Through the cooperation between them, the effect of precise positioning is achieved, the work efficiency is improved, and the problems of entanglement and accumulation in the later stage are avoided. After the feeding is completed, by starting the electric hydraulic rod 12, the anti-slip plate 13 is pushed down under the action of the electric hydraulic rod 12, and the upper pressure roller 9 is prevented from continuing to rotate.
