Description

Technical Field

[0001] This utility model relates to the field of conveyor belt processing technology, and more specifically, it relates to an automatic riveting device for conveyor belt fasteners. Background Technology

[0002] Automatic conveyor belt fastener riveting equipment is an automated tool for installing fasteners on conveyor belt joints. It is commonly used in conveyor belt maintenance in mines, logistics, and factories. In the past, conveyor belts were joined by manually hammering fasteners, which caused many problems. Workers used hammers to hammer the fasteners, resulting in uneven force, crooked fasteners, and weak joints.

[0003] The positioning of the conveyor belt and the nail belt relies entirely on visual inspection, resulting in large errors in the spacing between the nails, which affects the flatness of the joint. The clamping force is not adjustable, and for conveyor belts of different thicknesses, either the clamping force is not tight enough, causing displacement during riveting, or the pressure is too high, damaging the belt. Manually moving the riveting position is time-consuming, and the operation of both hands is easy to cause fatigue and poses a risk of injury. It is difficult to meet the batch riveting needs of mining, logistics and other scenarios. Utility Model Content

[0006] The present invention is further configured such that a fixed plate is provided on the support frame, and an adjusting screw is threadedly connected to the fixed plate. One end of the adjusting screw is rotatably connected to the movable plate to adjust the position of the movable plate.

[0007] The present invention is further configured such that a moving rod is slidably provided on the moving plate, a moving hole is provided on the adjusting screw, one end of the moving rod is fixedly connected to the pressing rod, and the other end extends into the moving hole, thereby restricting the position and direction of the pressing rod's movement.

[0008] The present invention is further configured such that one end of the lowering rod is provided with a traction rope, and the bottom of the traction rope is provided with a foot pedal, so that the position of the lowering rod can be easily moved through the foot pedal and the traction rope.

[0009] The present invention is further provided with guide wheels that rotate symmetrically on the support frame, which facilitates the turning and guiding of the traction rope.

[0010] The present invention is further provided that the support frame is provided with a guide seat that cooperates with the traction rope, so as to facilitate the guidance of the traction rope.

[0011] The present invention is further configured such that a sliding motor is connected to one side of the sliding frame, and the motor shaft of the sliding motor is fixedly connected to the sliding screw, so as to drive the sliding screw to rotate, and drive the sliding block and the fastener to move through the sliding screw.

[0021] Please see Figures 1-5 An automatic conveyor belt fastener riveting device includes a fastener machine body 1, a workbench 2, sliding frames 3 on both sides of the workbench 2, a sliding screw 4 on the sliding frame 3, a sliding block 5 threadedly connected to the sliding screw 4, a fastener 6 on the sliding block 5, a fastener groove 7 on the workbench 2, positioning magnets 8 on both sides of the fastener groove 7, a positioning frame 9 on one side of the fastener groove 7, a support frame 10 symmetrically provided at the end of the workbench 2, a pressing groove 11 on the support frame 10, a pressing rod 12 slidingly disposed in the pressing groove 11, a moving plate 13 on the support frame 10, a pressing spring 14 between the moving plate 13 and the pressing rod 12, a sliding motor 23 connected to one side of the sliding frame 3, the motor shaft of the sliding motor 23 being fixedly connected to the sliding screw 4, and positioning grooves 24 arrayed on the positioning frame 9.

[0022] In this embodiment, the conveyor belt uses a DK fastener connector. The fastener strap of the DK fastener connector is installed into the fastener groove 7, and the position of the fastener strap is fixed by the positioning magnet 8. At the same time, the fastener is inserted into the positioning frame 9 and snapped into the positioning groove 24. One end of the conveyor belt is inserted into the fastener, and both ends of the conveyor belt are fixed. The fastener and the fastener strap are riveted together by the fastener 6, and the fastener and the fastener strap are fixed to one side of the conveyor belt. The sliding screw 4 is rotated by the sliding motor 23, which in turn drives the sliding block 5 to move on the sliding frame 3 to adjust the position of the fastener 6, thereby completing the installation and fixing of the DK fastener connector of the conveyor belt. The installation method is simple, convenient and efficient. The fastener 6 adopts the DK fastener machine in the prior art.

[0023] Please see Figures 4-5 As one embodiment of pressing the conveyor belt: a fixed plate 15 is provided on the support frame 10, and an adjusting screw 16 is threadedly connected to the fixed plate 15. One end of the adjusting screw 16 is rotatably connected to the moving plate 13. A moving rod 17 is slidably provided on the moving plate 13. A moving hole 18 is provided on the adjusting screw 16. One end of the moving rod 17 is fixedly connected to the lower pressure rod 12, and the other end extends into the moving hole 18. A traction rope 19 is provided at one end of the lower pressure rod 12. A foot pedal 20 is provided at the bottom of the traction rope 19. Guide wheels 211 are symmetrically rotated on the support frame 10. A guide seat 22 that cooperates with the traction rope 19 is provided on the support frame 10.

[0024] More specifically, when clamping both ends of the conveyor belt, stepping on the foot pedal 20 causes it to move downwards. Under the guidance of the guide seat 22 and guide wheel 21, the traction rope 19 drives the pressure rod 12 to move upwards along the pressure groove 11, stretching the pressure spring 14 and extending the conveyor belt under the pressure rod 12. Releasing the foot pedal 20 allows the pressure rod 12 to initially press downwards through the elastic force of the pressure spring 14. Then, rotating the adjusting screw 16 causes it to rotate on the fixed plate 15, thereby driving the moving plate 13 to adjust its height. The moving rod 17 slides within the moving hole 18, limiting the position and direction of the pressure rod 12 and the moving plate 13. By adjusting the height of the moving plate 13, the deformation of the pressure spring 14 is adjusted, thereby adjusting the elastic force of the pressure rod 12 when pressing down on the conveyor belt, increasing the clamping force on the conveyor belt and improving practicality.

[0025] In summary, during the use or operation of the overall equipment: When in use, the conveyor belt uses a DK fastener connector. The fastener strap of the DK fastener connector is installed into the fastener groove 7, and the position of the fastener strap is fixed by the positioning magnet 8. Simultaneously, the fastener is inserted into the positioning frame 9 and snapped into the positioning groove 24. One end of the conveyor belt is inserted into the fastener, and both ends of the conveyor belt are fixed. The fastener and fastener strap are riveted together using the fastener 6, combining and fixing them to one side of the conveyor belt. The sliding motor 23 drives the sliding screw 4 to rotate, which in turn drives the sliding block 5 to move on the sliding frame 3, adjusting the position of the fastener 6, thus completing the installation and fixing of the DK fastener connector on the conveyor belt. The installation method is simple, convenient, and efficient. The fastener 6 uses the existing DK fastener machine.

[0026] When clamping both ends of the conveyor belt, stepping on the foot pedal 20 causes it to move downwards. Under the guidance of the guide seat 22 and guide wheel 21, the traction rope 19 drives the pressure rod 12 to move upwards along the pressure groove 11 and stretches the pressure spring 14, extending the conveyor belt under the pressure rod 12. Releasing the foot pedal 20 allows the pressure rod 12 to initially press downwards through the elastic force of the pressure spring 14. Then, rotating the adjusting screw 16 causes it to rotate on the fixed plate 15, thereby driving the moving plate 13 to adjust its height. The moving rod 17 slides within the moving hole 18, limiting the position and direction of the pressure rod 12 and the moving plate 13. By adjusting the height of the moving plate 13, the deformation of the pressure spring 14 is adjusted, thereby adjusting the elastic force of the pressure rod 12 when pressing down on the conveyor belt, increasing the clamping force on the conveyor belt and improving practicality.
