Description

Technical Field

[0001] This application relates to the field of belt splicing, and in particular to a belt splicing device. Background Technology

[0002] In the belt manufacturing industry, with the continuous development of industrial production, the demand for belts is increasing, especially in scenarios requiring longer belts, where belt splicing technology is particularly important. Good belt splicing technology can reduce the risk of belt breakage during use, lower equipment maintenance costs, and improve production efficiency.

[0003] In existing belt splicing technology, to make the spliced ​​belts more robust, a belt cutting device is usually used to cut the ends of the belts to be spliced ​​into a toothed shape, so that the teeth of the two belt ends intersect, and then they are heated, melted, and pressed together. In actual operation, the conventional method is to first clamp and fix the two ends of the belts on the workbench, and the worker uses a ruler to support the two ends of the belts so that the teeth of the two ends intersect. After that, the ruler is removed, and the worker manually uses a pressure plate to press down on the two crossed ends of the belts, so that the teeth of the two belt ends mesh tightly.

[0004] However, in large-scale production scenarios, a large number of belts need to be spliced ​​together. Manual operation not only consumes a lot of manpower and time, but also makes it difficult to ensure the consistency of quality at each splice. Utility Model Content

[0005] To address the issue that manual operation, which requires splicing a large number of belts, is not only labor-intensive and time-consuming, but also makes it difficult to ensure the consistency of quality at each splice, this application provides a belt splicing device.

[0006] The belt splicing device provided in this application adopts the following technical solution: A belt splicing device includes a worktable and a top wheel. A groove is formed on the worktable, and a support frame is fixed on the worktable. A pressure roller is connected to the support frame. Movable components are provided in both the support frame and the groove. One set of movable components is connected to the top wheel, and a mounting frame is connected to the other set of movable components. The mounting frame is provided with an elastic component that enables the pressure roller to press down on the belt splicing point. A drive mechanism is provided on the worktable, and the two sets of movable components are moved by the drive mechanism.

[0007] By implementing the above technical solution, the drive mechanism causes two sets of moving components to drive the top wheel and pressure roller to move synchronously. The top wheel lifts the toothed structure of the two belts upward, thereby creating an interlocking arrangement of the teeth at both ends. Under the action of the elastic component, the pressure roller continuously presses down on the interlocking teeth at the ends of the belts to ensure tight fixation at the belt joints.

[0008] Optionally, the moving component includes a threaded rod and a slider, the slider being threadedly connected to the threaded rod, one of the threaded rods rotating on a support frame, the other threaded rod rotating in a groove, one of the sliders sliding in the support frame and fixed to a mounting frame, and the other slider sliding in the groove and fixed to a top wheel.

[0009] By adopting the above technical solution, the threaded connection between the threaded rod and the slider allows the slider to move along the threaded rod when the threaded rod rotates, thereby realizing the movement of the mounting frame and the top wheel, and in turn driving the pressure roller and the top wheel to move.

[0010] Optionally, the elastic component includes a guide rod, a mounting plate, and a spring. The guide rod is fixed inside the mounting frame, the mounting plate passes through the guide rod and slides inside the mounting frame, the spring is coaxially sleeved on the guide rod, and the two ends of the spring are respectively on the inner wall of the mounting frame and the mounting plate, and the pressure roller rotates on the mounting plate.

[0011] By adopting the above technical solution, the guide rod makes the sliding of the mounting plate more stable, and the spring can provide elastic force to ensure that the pressure roller continuously applies downward pressure to the belt splice, so that the teeth at the ends of the two belts mesh tightly.

[0012] Optionally, the driving mechanism includes a driving component, two drive wheels, and a conveyor belt. The two drive wheels are coaxially fixed on two threaded rods, the driving component is connected to one of the threaded rods, and the two drive wheels are driven by the conveyor belt.

[0013] By adopting the above technical solution, the drive component is connected to one of the threaded rods, and the two transmission wheels are coaxially fixed on the two threaded rods and linked by belts to realize the connection of the two sets of moving components, so that the top wheel and the mounting frame move synchronously.

[0014] Optionally, the driving component is a servo motor, and the output end of the servo motor is coaxially fixed with one of the threaded rods.

[0015] By adopting the above technical solution, the driving component is set as a servo motor and its output end is coaxially fixed with one of the threaded rods. This allows for precise control of the rotation of the threaded rod, thereby precisely controlling the movement of the slider and enabling the top wheel and mounting bracket to move at the required speed and position.

[0016] Optionally, a protective cover is fixed on the worktable, the servo motor is located inside the protective cover, and the protective cover has heat dissipation holes.

[0017] By adopting the above technical solution, the protective cover protects the servo motor from external impacts; the heat dissipation holes ensure that the heat generated by the servo motor during operation can be dissipated, preventing the motor from being damaged due to overheating and ensuring the normal operation of the servo motor.

[0018] Optionally, the workbench is provided with a clamping assembly for fixing the belts to be spliced.

[0019] By adopting the above technical solution, clamping components are set on the workbench to fix the belt to be spliced, which can prevent the belt from shifting during the splicing process, ensure the smooth progress of the splicing work, and improve the accuracy and stability of the splicing.

[0020] Optionally, a pressing device is provided above the workbench, a pressure plate is fixed on the pressing device, and a heating device is provided inside the pressure plate.

[0021] By adopting the above technical solution, during belt splicing, the pressing device can drive the pressing plate to move down, and the heating device inside the pressing plate can heat the belt splicing area, melting the belt and improving the firmness of the belt splicing.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The drive mechanism drives the top wheel to move through the moving component. The top wheel lifts the toothed structure of the two belts upward, so that the teeth at both ends form an interlocking arrangement. 2. The drive mechanism moves the pressure roller through the moving component, and under the action of the elastic component, the pressure roller continuously presses down on the interlocking teeth at the end of the belt to ensure that the belt splice is tightly fixed.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses a belt splicing device.

[0028] Reference Figure 1 A belt splicing device is disclosed, used for splicing belts with toothed ends. The device includes a worktable 1, on which clamping components 12 are mounted. In this embodiment, two sets of clamping components 12 are provided, arranged in parallel. Each clamping component 12 includes a clamping block, a bolt, and a nut, wherein the bolt rotates on the worktable 1, and the nut is threaded onto the bolt. The clamping components 12 are used to fix the belt to be spliced ​​on the worktable 1, preventing the belt from shifting during the splicing process and affecting the splicing quality.

[0029] Reference Figure 1 When it is necessary to secure the belt to be spliced, place the clamping block on the belt, then turn the bolt to make it snap into the clamping block, and tighten the nut to gradually tighten and secure the clamping block, thereby firmly clamping the belt to be spliced ​​on the worktable 1. This clamping method is not only easy to operate, but also ensures that the belt remains stable during the splicing process and will not shift or loosen due to external forces.

[0030] Reference Figure 1 A pressing device 13 is provided on the workbench 1. In this embodiment, a pressure plate 14 is fixed on the pressing device 13, which is usually made of aluminum plate and has good thermal conductivity. In addition, a cavity is opened in the middle of the pressure plate 14, and a heating device 15 is provided inside the cavity. The heating device 15 can heat and melt the belt splice area by means of heating plates or electromagnetic heating to realize the splicing of the two ends of the belt.

[0031] Reference Figure 2A support frame 4 is fixedly installed on the workbench 1, and a groove 3 is formed in the workbench 1, with the groove 3 arranged parallel to the support frame 4. Moving components 6 are provided in both the support frame 4 and the groove 3, and the two sets of moving components 6 work together via a drive mechanism 9. The moving component 6 located in the groove 3 is connected to a top wheel 2, and the moving component 6 located on the support frame 4 is connected to a mounting frame 7, on which an elastic component 8 is provided. A pressure roller 5 is installed on the elastic component 8, and the elastic component 8 is used to press down on the belt splice joint of the pressure roller 5.

[0032] Reference Figure 2 The top roller 2 moves below the belt splice to lift the toothed structures at the ends of the two belts, causing their teeth to interlock in a staggered arrangement. The pressure roller 5 moves above the belt splice and applies pressure to the belt. The top roller 2 and the pressure roller 5 are offset to ensure that the pressure roller 5 can apply pressure to the interlocking teeth at the ends of the two belts, completing the initial pressing and positioning.

[0033] Reference Figure 2 and Figure 3 The moving assembly 6 includes a threaded rod 61 and a slider 62, with the slider 62 threadedly connected to the threaded rod 61. Two sets of moving assemblies 6 are configured to drive the top wheel 2 and the pressure roller 5 to move, respectively. One threaded rod 61 is rotatably mounted on the support frame 4, and the other threaded rod 61 is rotatably mounted inside the groove 3. One slider 62 can slide within the support frame 4 and is fixed to the mounting frame 7, while the other slider 62 can slide within the groove 3 and is fixed to the top wheel 2.

[0034] Reference Figure 3 The drive mechanism 9 includes a drive component, two drive wheels 92, and a conveyor belt 93. In this embodiment, the drive component is a servo motor 91, whose output end is coaxially fixed to one of the threaded rods 61. The two drive wheels 92 are coaxially fixed to the two threaded rods 61 respectively. The conveyor belt 93 is annular and can be a synchronous belt made of rubber or a regular V-belt. The two drive wheels 92 are linked together through the conveyor belt 93.

[0035] Reference Figure 2 and Figure 3 A controller 16 is installed on the side wall of the workbench 1. The controller 16 is electrically connected to the servo motor 91. By operating the controller 16, the starting and rotation direction of the servo motor 91 can be controlled.

[0036] Reference Figure 2 and Figure 3 When the servo motor 91 drives the threaded rod 61 to rotate, the other threaded rod 61 will also rotate synchronously through the coordinated transmission of the transmission wheel 92 and the conveyor belt 93, thereby causing the slider 62 to move along the axial direction of the threaded rod 61.

[0037] Reference Figure 2 and Figure 3 With the cooperation of the drive mechanism 9 and the moving component 6, the top wheel 2 moves at the bottom of the joint of the two belts, lifting the toothed ends of the belts so that the teeth at both ends form an interlocking arrangement. In addition, under the action of the drive mechanism 9 and the moving component 6, the pressure roller 5, which is located above the joint of the belts and exerts a squeezing effect on the belts, effectively presses the already interlocking teeth together.

[0038] Reference Figure 1 and Figure 3 A protective cover 10 is fixed on the workbench 1. The protective cover 10 is a box structure used to protect the servo motor 91. Heat dissipation holes 11 are provided on the protective cover 10. The holes are round or square to ensure that the heat generated by the servo motor 91 during operation is dissipated and to prevent the servo motor 91 from overheating and being damaged.

[0039] Reference Figure 4 The elastic component 8 includes a guide rod 81, a mounting plate 82, and a spring 83. The guide rod 81 is fixed inside the mounting frame 7 and provides guidance for the movement of the mounting plate 82. A hole adapted to the guide rod 81 is opened at the center of the mounting plate 82, allowing the guide rod 81 to pass through and slide within the mounting frame 7. The spring 83 is coaxially sleeved on the guide rod 81, with its two ends abutting against the inner wall of the mounting frame 7 and the mounting plate 82, respectively.

[0040] Reference Figure 2 and Figure 4 The pressure roller 5 is rotatably mounted on the mounting plate 82. When the mounting plate 82 is subjected to external force, it will compress the spring 83, causing the pressure roller 5 to exert pressure on the belt splice. The elasticity of the spring 83 ensures that the pressure roller 5 exerts uniform and stable pressure on the belt splice.

[0041] When using this device, first align the toothed ends of the two belts to be spliced, and then fix both ends of the belts to the worktable 1 using two sets of clamping components 12 to ensure that the splicing part is in the correct working position. Next, lift the splicing end of the belt, start the servo motor 91, and drive the two sets of moving components 6 to move synchronously through the drive mechanism 9, so that the top wheel 2 in the trough 3 moves precisely below the belt splicing point.

[0042] Once the top roller 2 reaches the predetermined position, the belt is lowered to contact the top roller 2. The servo motor 91 continues to drive the top roller 2 to move axially along the worktable 1. During the movement, the top roller 2 lifts the toothed structures at the ends of the two belts, causing the teeth at both ends to naturally form an interlocking state. At the same time, the pressure roller 5 above moves synchronously under the drive of the moving component 6. The pressure roller 5, through the action of the elastic component 8, applies uniform pressure to the interlocking teeth, making the teeth fit tightly together and completing the initial pressing and positioning.

[0043] After the initial pressing is completed, silicone paper is laid at the splice to prevent adhesion. The pressing device 13 is started to lower the pressing plate 14 to the splice area. After adjusting the position, the heating device 15 is started. The heat is conducted to the splice area through the aluminum plate, so that the toothed structure is heated and melted and fully fused. After cooling, the two belts are firmly spliced.

[0044] The implementation principle of the belt splicing device in this application embodiment is as follows: The belt splicing device drives two sets of moving components 6 to move synchronously through the drive mechanism 9, so that the top wheel 2 and the pressure roller 5 work together. The top wheel 2 causes the toothed structures at the ends of the two belts to interlock in an alternating manner. The pressure roller 5 performs preliminary pressing on the interlocking belt splice, making the two belt ends fit more tightly. By setting the elastic component 8 on the mounting frame 7, the pressure of the pressure roller 5 on the belt splice is ensured to be uniform and stable, improving the splicing quality. Compared with the manual operation method of the prior art, this device greatly improves the efficiency and quality of belt splicing, meeting the needs of large-scale production.
