Description

Technical Field

[0001] This utility model belongs to the field of furnace belt correction technology, specifically a device for correcting the belt alignment of an LED furnace. Background Technology

[0002] The web guiding device is mainly used to correct the lateral deviation of the roll material during the transmission process. As a basic piece of equipment in industrial production, it forms a closed-loop control through sensor detection and linkage with the drive system. It supports multiple web guiding modes such as edge following, centering, and line following. It is widely used in continuous production lines such as printing, packaging, building materials, and coating. The device adopts an electromechanical or hydraulic drive system, equipped with low-friction ball bushings and a durable cast iron base structure. It achieves precise positioning of 1930mm wide roll material by adjusting the displacement of the swing bracket around the fixed point by ±7.5°.

[0003] A patent with publication number CN110817538A discloses an automatic belt deviation correction device for a heat treatment mesh belt furnace. The device includes: a left-side deviation detection mechanism mounted on the idler rollers of the mesh belt furnace and located on the left side of the mesh belt; a right-side deviation detection mechanism mounted on the idler rollers of the mesh belt furnace and located on the right side of the mesh belt; a left-side linear drive mechanism connected to the left-side sliding bearing of the idler rollers of the mesh belt furnace; a right-side linear drive mechanism connected to the right-side sliding bearing of the idler rollers of the mesh belt furnace; and a PLC controller, which is connected to the left and right deviation detection mechanisms and the left and right linear drive mechanisms respectively. When the PLC controller receives a deviation signal from either the left or right deviation detection mechanism that exceeds a critical point, the PLC controller sends a deflection signal to the left or right linear drive mechanism to perform a correction action. This allows for timely and effective adjustment of mesh belt deviation faults, saving labor costs and improving the stable production rate of the mesh belt furnace.

[0004] In current technologies, transmission belts are typically tensioned at both ends by tensioning pulleys. The material is placed in the center of the transmission belt, causing it to be subjected to high temperatures and tension for extended periods. This results in the central part of the transmission belt collapsing and deforming under stress. The center and sides of the tensioning pulleys shift under uneven stress, making it easy for the tensioning pulleys to become non-parallel or non-perpendicular to the center line of the transmission belt after tensioning. This leads to uneven tension on both sides of the transmission belt, generating lateral forces and causing the transmission belt to deviate towards the side with greater tension.

[0005] Therefore, a device for correcting the deviation of an LED furnace is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the above-mentioned problems, a device for correcting the deviation of an LED furnace belt is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The LED furnace belt correction device of this utility model includes a support frame and transmission wheels arranged on both sides of the support frame, a transmission track movably sleeved on the outer surface of the transmission wheels, and a fixed base fixedly installed on the top surface of the support frame and located on both sides of the support frame. Two sets of retractable rods are movably sleeved on the outer surface of the fixed base. A retainer is fixedly connected to the other end of the retractable rod. A spring arranged in the middle position between the fixed base and the retainer is movably sleeved on the outer surface of the retractable rod. A limiting nut is provided on the outer surface of one end of the retractable rod and movably sleeved on the outer surface of the fixed base. A limiting rod is provided on the inner wall of the retainer. A correction wheel is movably sleeved on the outer surface of the limiting rod.

[0008] Preferably, a switch button is located on one side surface of the fixed base and between the two retractable rods, and a hydraulic rod is provided on the outer side surface of the fixed base and at one edge of the switch button.

[0009] Preferably, a mating snap fastener is provided on one side surface of the retainer, and one end of the mating snap fastener is movably connected to the output end of the switch button.

[0010] Preferably, a fixing plate is fixedly connected to the outer surface of the limiting rod and at the two side edges, and an elastic wire is fixedly connected to the outer surface of the fixing plate.

[0011] Preferably, two sets of bonding discs are movably sleeved on the outer surface of the limiting rod, and the other end of the elastic wire is fixedly connected to the outer surface of the bonding disc, and the outer surface of the bonding disc is movably overlapped with the outer surface of the straightening wheel.

[0012] Preferably, a wear-resistant anti-slip strip is provided on the outer surface of the straightening wheel and on the surface of the arc-shaped groove, and a limit strip is fixedly connected to both ends of the wear-resistant anti-slip strip.

[0013] Preferably, a hollow groove is formed on the outer surface of the straightening wheel and on the surface of the arc-shaped groove, and the outer surface of the limiting strip is fixedly connected to the inner wall of the hollow groove.

[0014] Preferably, the outer surface of the wear-resistant and anti-slip strip is provided with a parallel cut at the middle position, the outer surface of the parallel cut is movably overlapped with the outer surface of the conveyor belt, and the two ends of the wear-resistant and anti-slip strip are slidably overlapped with the inner wall of the hollow groove.

[0015] Preferably, an anti-collision strip is provided on the outer surface of the straightening wheel at the middle position, and multiple sets of silicone soft blocks are fixedly connected to the outer surface of the anti-collision strip.

[0016] Preferably, one end of the silicone block is movably attached to the inner wall of the wear-resistant and anti-slip strip, and the outer surface of the wear-resistant and anti-slip strip is movably attached to the outer surface of the conveyor belt.

[0017] The beneficial effects of this utility model are: This utility model provides a device for correcting the deviation of an LED furnace belt. When the drive wheel drives the conveyor belt to rotate, the correction wheel on the outer surface of the limit rod engages with the two side edges of the conveyor belt. If the conveyor belt deviates from the surface of the drive wheel, the conveyor belt will squeeze the surface of the correction wheel and drive the retainer on the outer surface of the limit rod to squeeze and extend the retracting rod, causing the retracting rod to slide on the surface of the fixed base. When the retracting rod slides, it will drive the spring on the outer surface of the retracting rod to be compressed. At this time, the reverse pushing force of the compressed spring will elastically push the retainer, thereby causing the conveyor belt to gradually return to its original position on the surface of the drive wheel. This utility model provides a device for correcting the deviation of an LED furnace belt. When the spring deviates too much from the surface of the transmission wheel, the reverse force of the spring cannot reset the correction wheel. The retainer will gradually compress the retraction rod, causing the mating clamp to press one end of the switch button, thereby supplying power to the electro-hydraulic system. The electro-hydraulic system then starts the hydraulic rod, causing it to extend and retract, pushing the retainer. The maximum stroke of the hydraulic rod can adjust the conveyor belt and allow it to return to its original position. While controlling the hydraulic rod, the electro-hydraulic system's internal PLC program automatically starts, stops, and restores the hydraulic rod. The hydraulic rod returns to its original position after extending to its maximum stroke. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] Please see Figure 1 - Figure 4 This utility model provides a device for correcting the deviation of an LED furnace belt, including a support frame 11 and transmission wheels 111 disposed on the two side edges of the support frame 11, a conveyor belt 112 movably sleeved on the outer surface of the transmission wheels 111, a fixed base 12 fixedly installed on the top surface of the support frame 11 and located at the two side edges, two sets of retractable rods 121 movably sleeved on the outer surface of the fixed base 12, a retainer 124 fixedly connected to the other end of the retractable rods 121, a spring 122 movably sleeved on the outer surface of the retractable rods 121 disposed in the middle position between the fixed base 12 and the retainer 124, a limiting nut 123 movably sleeved on the outer surface of one end of the retractable rods 121, a limiting rod 125 disposed on the inner side wall of the retainer 124, a correcting wheel a4 movably sleeved on the outer surface of the limiting rod 125, the correcting wheel a4 being a roller with the center recessed inward; During operation, when the drive wheel 111 drives the conveyor belt 112 to rotate, the straightening wheel a4 on the outer surface of the limiting rod 125 engages with the two side edges of the conveyor belt 112. If the conveyor belt 112 deviates from the surface of the drive wheel 111, the conveyor belt 112 will squeeze the surface of the straightening wheel a4, and drive the retainer 124 on the outer surface of the limiting rod 125 to compress and extend the retraction rod 121, causing the retraction rod 121 to slide on the surface of the fixed base 12. When the retraction rod 121 slides, it will cause the spring 122 on the outer surface of the retraction rod 121 to be compressed. At this time, the reverse pushing force of the compressed spring 122 will elastically push the retainer 124, thereby causing the conveyor belt 112 to gradually return to its original position on the surface of the drive wheel 111.

[0023] Furthermore, such as Figures 1 to 5 As shown, a switch button 126 is located on one side surface of the fixed base 12 and between the two retractable rods 121. A hydraulic rod 128 is provided on the outer surface of the fixed base 12 and at one edge of the switch button 126. A mating clamp 127 is provided on one side surface of the retainer 124. One end of the mating clamp 127 is movably connected to the output end of the switch button 126. The hydraulic rod is usually in the form of a cylindrical structure and is mainly composed of piston rod, cylinder, seals and other components. Its core working principle is based on Pascal's law, which amplifies the force by transmitting pressure through a closed liquid.

[0024] During operation, when the spring 122 deviates too much from the surface of the transmission wheel 111, the reverse force of the spring 122 cannot reset the straightening wheel a4. The retainer 124 then gradually compresses the retraction rod 121, causing the mating clamp 127 to press and activate one end of the switch button 126. This powers the electro-hydraulic system, which in turn activates the hydraulic rod 128, causing it to extend and retract, pushing the retainer 124. The maximum stroke of the hydraulic rod 128 adjusts the conveyor belt 112, allowing it to return to its original position. Simultaneously, the electro-hydraulic system controls the hydraulic rod 128, and its internal PLC program automatically starts, stops, and restores it. The hydraulic rod 128 returns to its original position after reaching its maximum stroke.

[0025] Furthermore, such as Figures 1 to 5As shown, a wear-resistant anti-slip strip a7 is provided on the outer surface of the straightening wheel a4 and on the surface of the arc-shaped groove. Limiting strips a6 are fixedly connected to both ends of the wear-resistant anti-slip strip a7. A hollow groove a5 is opened on the outer surface of the straightening wheel a4 and on the surface of the arc-shaped groove. The outer surface of the limiting strip a6 is fixedly connected to the inner wall of the hollow groove a5. A parallel cut is provided on the outer surface of the wear-resistant anti-slip strip a7 at the middle position. The outer surface of the parallel cut is movably overlapped with the outer surface of the conveyor belt 112. The two ends of the wear-resistant anti-slip strip a7 are slidably overlapped with the inner wall of the hollow groove a5. An anti-collision strip a8 is provided on the outer surface of the straightening wheel a4 at the middle position. Multiple sets of silicone soft blocks a9 are fixedly connected to the outer surface of the anti-collision strip a8.

[0026] During operation, after the conveyor belt 112 is attached to the inside of the straightening wheel a4, the wear-resistant anti-slip strip a7 inside the straightening wheel a4 preferentially attaches to the outer surface of the conveyor belt 112. At this time, the wear-resistant anti-slip strip a7 increases the anti-slip and wear resistance between the conveyor belt 112 and the conveyor belt 112. When the conveyor belt 112 is continuously squeezed and pushed, the anti-collision strip a8 and the silicone soft block a9 provide elastic buffering treatment for the compression of the conveyor belt 112, reducing the wear of the wear-resistant anti-slip strip a7 caused by the rapid sliding of the side of the conveyor belt 112 on the surface of the wear-resistant anti-slip strip a7.

[0027] Furthermore, such as Figures 1 to 5 As shown, a fixed plate a1 is fixedly connected to the outer surface of the limiting rod 125 and located at the two side edges. An elastic wire a2 is fixedly connected to the outer surface of the fixed plate a1. Two sets of fitting plates a3 are movably sleeved on the outer surface of the limiting rod 125. The other end of the elastic wire a2 is fixedly connected to the outer surface of the fitting plate a3. The outer surface of the fitting plate a3 is movably overlapped with the outer surface of the straightening wheel a4. One end of the silicone soft block a9 is movably overlapped with the inner wall of the wear-resistant anti-slip strip a7. The outer surface of the wear-resistant anti-slip strip a7 is movably overlapped with the outer surface of the conveyor belt 112.

[0028] During operation, when the conveyor belt 112 slides rapidly, slight vibrations occur on its side, causing the straightening wheel a4 to slide up and down on the outer surface of the limit rod 125. The elastic wire a2 on the outer surface of the straightening wheel a4 provides elastic buffering, allowing the straightening wheel a4 to change along with the up-and-down swing amplitude of the conveyor belt 112. Furthermore, the elastic buffering of the elastic wire a2 keeps the straightening wheel a4 in the center position of the limit rod 125. The elastic extension and contraction of the elastic wire a2 provides soft pushing and squeezing to the conveyor belt 112, greatly reducing the swaying amplitude of the conveyor belt 112 without forcefully blocking its movement.

[0029] Working principle: When the transmission wheel 111 drives the conveyor belt 112 to rotate, the straightening wheel a4 on the outer surface of the limiting rod 125 engages with the two side edges of the conveyor belt 112. If the conveyor belt 112 deviates from the surface of the transmission wheel 111, the conveyor belt 112 will squeeze the surface of the straightening wheel a4, and drive the retainer 124 on the outer surface of the limiting rod 125 to squeeze and extend the retracting rod 121, causing the retracting rod 121 to slide on the surface of the fixed base 12. When the retracting rod 121 slides, it will drive the spring 122 on the outer surface of the retracting rod 121 to be compressed. At this time, the reverse pushing force of the spring 122 after being compressed will elastically push the retainer 124, thereby causing the conveyor belt 112 to gradually return to its original position on the surface of the transmission wheel 111. When the spring 122 deviates too much from the surface of the transmission wheel 111, the reverse force of the spring 122 cannot reset the straightening wheel a4. The retainer 124 will gradually compress the retraction rod 121, thereby causing the mating clamp 127 to press one end of the switch button 126, which will then supply power to the electro-hydraulic system and start the hydraulic rod 128, causing the hydraulic rod 128 to extend and push, and push the retainer 124. According to the maximum stroke of the hydraulic rod 128, the conveyor belt 112 can be adjusted and returned to its original position. While the electro-hydraulic system controls the hydraulic rod 128, its internal PLC program will automatically start, stop, and restore the hydraulic rod 128. The hydraulic rod 128 will restore itself after extending to its maximum stroke.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
