Description

Technical Field

[0001] This utility model relates to the field of conveyor belt repair technology, and in particular to an auxiliary repair device for conveyor belt bonding. Background Technology

[0002] Conveyor belts are flexible transport equipment used to transport materials and are widely used in many industries such as mining, metallurgy, chemical industry, port, power, and building materials. When using conveyor belts, problems such as longitudinal penetrating tears, local impact abrasion, edge damage, local scratches, blistering of the belt surface rubber, and glue injection often occur.

[0003] In the existing technology, the repair of conveyor belts is mostly carried out by injecting glue with a glue gun, applying repair strips and diamond-shaped patches. After the glue is filled, in order to ensure the repair quality and stability of the patch, it is necessary to manually press the filled part to release air, which is laborious and difficult to carry out fast and efficient repair. Utility Model Content

[0004] The purpose of this invention is to address the problem that in the existing technology, conveyor belt repair is mostly carried out by injecting glue with a glue gun, applying repair strips and diamond-shaped patches, etc. After the repair is completed and the glue is filled, in order to ensure the repair quality and stability of the patch, it is necessary to manually press the filled part to release air, which is laborious and difficult to achieve fast and efficient repair. Therefore, this invention proposes an auxiliary repair device for conveyor belt bonding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auxiliary repair device for conveyor belt bonding includes a frame and a pressing roller. The inner wall of the frame has a strip-shaped opening. The two ends of the pressing roller are slidably disposed on the inner wall of the frame at the strip-shaped opening. A movable frame is slidably disposed on the outer side of the frame. A motor is fixedly connected to the side wall of the movable frame. The two ends of the pressing roller are rotatably connected to the inner wall of the movable frame. The output shaft of the motor is fixedly connected to the end of the pressing roller. A connecting plate is fixedly connected to the side wall of the movable frame. A cylinder is fixedly connected to the inner wall of the top of the frame. The piston rod end of the cylinder is fixedly connected to the bottom of the connecting plate. A support roller is rotatably connected inside the frame.

[0007] Preferably, mounting plates are fixedly connected to both sides of the bottom end of the frame.

[0008] Preferably, the inner wall of the idler roller has a cavity, and the two ends of the idler roller have through holes respectively. A controller is fixedly connected to the side wall of the frame. A heating tube is rotatably connected to the inner wall of the idler roller located in the through hole. A connecting tube is electrically connected to the side wall of the heating tube. The end of the connecting tube away from the heating tube is electrically connected to the controller.

[0009] Preferably, a fixing frame is fixedly connected to the side wall of the frame, and the heating tube is fixedly connected to the inner wall of the fixing frame.

[0010] Preferably, both ends of the idler roller extend into the interior of the fixed frame and are fixedly connected with retaining rings.

[0011] Preferably, a plurality of supporting heat-conducting disks are fixedly sleeved on the wall of the heating tube, and a plurality of spherical grooves are respectively opened around the inner wall of the plurality of supporting heat-conducting disks, and wear-resistant balls are respectively rolled on the inner wall of the plurality of spherical grooves.

[0012] Compared with the prior art, the present invention provides an auxiliary repair device for conveyor belt bonding, which has the following beneficial effects:

[0013] 1. This auxiliary repair device for conveyor belt bonding uses the extension and retraction of the piston rod of a cylinder to move the connecting plate and the movable frame up and down, thereby adjusting the distance between the extrusion roller and the idler roller. This allows the extrusion roller to contact the conveyor belt and provide a certain pressure, ensuring a tight fit between the extrusion roller and the conveyor belt, facilitating bonding repair operations. The output shaft of the motor drives the extrusion roller to rotate. The extrusion roller cooperates with the idler roller to extrude pressure on the conveyor belt. During the extrusion process, the rotation of the extrusion roller allows the conveyor belt to move on the idler roller, achieving extrusion repair of the bonding area of ​​the conveyor belt and ensuring the bonding effect.

[0014] 2. This auxiliary repair device for conveyor belt bonding uses a controller to energize the heating tube, which generates heat. The heating tube is fixed to the inner wall of the fixed frame, and its side wall is electrically connected to the controller through a connecting pipe. This allows for precise control of the heating temperature and time of the heating tube. The heat generated by the heating tube is transferred to the idler roller, which then transfers the heat to the conveyor belt, heating the bonding area of ​​the conveyor belt, accelerating the curing of the adhesive, and improving the bonding effect.

[0015] 3. The auxiliary repair device for conveyor belt bonding can prevent the heating tube from shifting during rotation by using the retaining rings at both ends of the idler roller, ensuring the stability and uniformity of heating. The heat generated by the heating tube is transferred through the supporting heat-conducting disk. Multiple supporting heat-conducting disks can evenly distribute the heat. Wear-resistant balls are rolled in the spherical grooves on the inner wall of the supporting heat-conducting disk, reducing the friction between the heating tube and the supporting heat-conducting disk, and at the same time helping the heat conduction.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

A cylinder 6 is fixedly connected to the inner wall of the top of the frame 1. The piston rod end of the cylinder 6 is fixedly connected to the bottom of the connecting plate 5. A support roller 7 is rotatably connected inside the frame 1. Mounting plates 8 are fixedly connected to both sides of the bottom end of the frame 1.

The idler roller 7 is rotatably connected to the inner wall of the through hole. A connecting pipe 11 is electrically connected to the side wall of the heating pipe 10.

A fixing frame 12 is fixedly connected to the side wall of the frame 1, and the heating pipe 10 is fixedly connected to the inner wall of the fixing frame 12.

[0024] Start cylinder 6. The piston rod of cylinder 6 extends and retracts, causing the connecting plate 5 and the movable frame 3 to move up and down, thereby adjusting the distance between the extrusion roller 2 and the idler roller 7. This allows the extrusion roller 2 to contact the conveyor belt and provide a certain pressure, ensuring that the extrusion roller 2 and the conveyor belt are tightly fitted, facilitating the bonding and repair operation. Start motor 4. The output shaft of motor 4 drives the extrusion roller 2 to rotate. The extrusion roller 2 cooperates with the idler roller 7 to extrude pressure on the conveyor belt. During the extrusion process, the rotation of the extrusion roller 2 allows the conveyor belt to move on the idler roller 7, realizing the extrusion and repair of the bonding area of ​​the conveyor belt and ensuring the bonding effect.

The heating tube 10 is fixed to the inner wall of the fixing frame 12, and its side wall is electrically connected to the controller 9 through the connecting pipe 11. The heating temperature and time of the heating tube 10 can be precisely controlled. The heat generated by the heating tube 10 is transferred to the idler roller 7, and the idler roller 7 then transfers the heat to the conveyor belt, so that the bonding area of ​​the conveyor belt is heated, which accelerates the curing of the adhesive and improves the bonding effect.

[0026] To distribute heat evenly, such as Figure 1-4 As shown, the two ends of the roller 7 extend into the interior of the fixed frame 12 and are fixedly connected with retaining rings 13. Multiple supporting heat-conducting disks 14 are fixedly sleeved on the wall of the heating tube 10. Multiple spherical grooves are opened around the inner wall of the multiple supporting heat-conducting disks 14. Wear-resistant balls 15 are rolled on the inner wall of the multiple spherical grooves.

[0027] The retaining rings 13 at both ends of the roller 7 can prevent the heating tube 10 from shifting during rotation, ensuring the stability and uniformity of heating. The heat generated by the heating tube 10 is transferred through the supporting heat-conducting disk 14. Multiple supporting heat-conducting disks 14 can evenly distribute the heat. The wear-resistant ball 15 is rolled in the spherical groove on the inner wall of the supporting heat-conducting disk 14, reducing the friction between the heating tube 10 and the supporting heat-conducting disk 14, and at the same time helping the heat conduction.
