Description

Technical Field

[0001] This utility model relates to the field of synchronous belt processing technology, and in particular to a synchronous belt splicing machine. Background Technology

[0002] Synchronous belts are transmission components that combine the advantages of chain, gear, and belt drives. They consist of a strong layer, a toothed layer, and a fabric layer. The strong layer is usually made of materials such as glass fiber and steel wire, providing high strength and low elongation. The toothed layer is made of polyurethane or rubber and has an equidistant tooth structure on the inside, which can precisely mesh with the tooth grooves on the pulley to achieve synchronous transmission without slippage.

[0003] Synchronous belt splicing machines are specialized equipment for connecting synchronous belt joints. They are mainly used for the production of seamless synchronous belts or the repair of damaged synchronous belts. Their working principle is to use heating and pressurization to melt the joint of the synchronous belt at high temperature and bond it together to form a complete ring structure.

[0004] In daily work, it has been found that existing synchronous belt coupling machines lack effective protective mechanisms. When hands or limbs are near the work area, it is very easy to accidentally touch the control components of the equipment (such as the cylinder start switch). Once an accidental contact occurs, the coupling machine's cylinder will suddenly start and perform pressurization, heating, and other working actions. If the operator's limbs have not yet moved away from the work area, they may be squeezed or burned by the cylinder or related moving parts, causing direct personal injury, affecting work efficiency, and posing a great threat to the personal safety of the operators. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the prior art that, in the event of an accidental collision, the cylinder of the connector will suddenly start and perform pressurization, heating and other working actions. If the operator's limbs have not yet left the work area, they may be squeezed or burned by the cylinder or related moving parts, causing direct personal injury. Therefore, a synchronous belt connector is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a synchronous belt coupling machine, including a workbench, two supports are mounted on the surface of the workbench, a cylinder is mounted on the support and a movable plate is fixedly connected to the output end, a heating plate one is mounted on the surface of the movable plate, a heating plate two is mounted on the surface of the support, and an auxiliary device is provided on the surface of the support. The auxiliary device includes a support frame fixed to both sides of the bracket. A limit block is slidably connected to the inner wall of the support frame. One side of each limit block has an inclined surface. Two springs are fixedly connected to the corresponding side of each limit block and the support frame. Push rods are fixedly connected to the surfaces of the two limit blocks, and these push rods are slidably connected to the inner wall of the support frame. An auxiliary block is bolted to the surface of the moving plate. When the equipment is not in operation, the auxiliary block is positioned above the limit block. If an accidental contact occurs, causing the cylinder to operate, the limit block can restrict the auxiliary block, preventing the moving plate and heating plate from pressing down further and reducing the risk of injury.

[0007] Preferably, two guide rods are fixedly connected to the surface of the support frame. The guide rods are slidably connected to the inner wall of the limiting block. The spring is sleeved on the guide rod. Through the above components, the two guide rods can guide not only the limiting block but also the spring.

[0008] Preferably, the inclined surface of the limiting block is provided with a groove, and the inner wall of the groove is rotatably connected to multiple sets of rollers. Through the above components, when the moving plate is reset, it can drive the auxiliary block to contact the rollers on the inclined surface, thereby reducing the friction between them.

[0009] Preferably, the surface of the auxiliary block is fixedly connected with an insert block, and the surface of the movable frame is provided with a slot. The insert block is inserted into the inner wall of the slot. Through the above components, the auxiliary block further improves the strength and stability of the auxiliary block after installation by inserting the insert block into the slot.

[0010] Preferably, the insert is T-shaped.

[0011] Preferably, the push rod includes two push rods and a push plate, with the two push rods fixed to the surface of the push plate.

[0012] Preferably, a limiting component is provided on the side of the bracket near the second heating plate. The limiting component includes multiple stops that are slidably connected to the inner wall of the bracket. A bidirectional screw is rotatably connected to the inner wall of the bracket. The bidirectional screw is threadedly connected to the inner wall of the stops. Through the above components, the bidirectional screw can be rotated, and the bidirectional screw can control the position of the stops. The stops can limit the mold on which the timing belt is placed, ensuring the stability of the placement. Preferably, a knob is fixedly connected to one end of the bidirectional screw.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, through the auxiliary device, when the equipment is in a non-working state, the limiting block is kept in a reset state under the action of the spring, and its position corresponds to the auxiliary block. If an accidental contact causes the cylinder to start unexpectedly, the limiting block will directly block the auxiliary block from moving down, thereby limiting the downward movement of the moving plate and the heating plate, reducing the risk of operators being squeezed or burned by suddenly pressing parts when placing the timing belt or approaching the work area. When the moving plate is reset, the auxiliary block can cooperate with the inclined plane to move the limiting block and automatically achieve the reset.

[0014] In this invention, by rotating the knob to drive the bidirectional screw to rotate, the position of the limiting block can be adjusted according to the mold size, so that the mold on which the timing belt is placed is restricted on the heating plate two, thereby improving the stability effect.

[0017] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a synchronous belt coupling machine, including a workbench 1, two supports 2 are installed on the surface of the workbench 1, a cylinder 3 is installed on the support 2, and a moving plate 4 is fixedly connected to the output end. A heating plate 5 is installed on the surface of the moving plate 4, a heating plate 6 is installed on the surface of the support 2, and an auxiliary device 7 is provided on the surface of the support 2. The auxiliary device 7 includes a support frame 71 fixed to both sides of the bracket 2. A limit block 72 is slidably connected to the inner wall of the support frame 71. A slope 73 is provided on one side of the limit block 72. A spring 76 is fixedly connected to the side of the limit block 72 corresponding to the support frame 71. There are two springs 76. Push rods 77 are fixedly connected to the surfaces of the two limit blocks 72. The push rods 77 are slidably connected to the inner wall of the support frame 71. The push rods 77 include two push rods 772 and a push plate 771. The two push rods 772 are fixed to the surface of the push plate 771. An auxiliary block 78 is installed on the surface of the movable plate 4 by bolts. A groove is provided on the slope 73 of the limit block 72. Multiple sets of rollers 74 are rotatably connected to the inner wall of the groove.

[0018] In this embodiment: when the device is not working, the auxiliary block 78 is located above the limiting block 72. Once an accidental contact occurs, the cylinder 3 is activated, and the limiting block 72 can restrict the auxiliary block 78, preventing the moving plate 4 and the heating plate 5 from continuing to press down, thus reducing the possibility of accidental injury. When the cylinder 3 drives the pressed moving plate 4 to reset, it can drive the auxiliary block 78 to contact the roller 74 of the inclined surface 73, thereby reducing the friction between them.

[0019] Preferably, two guide rods 75 are fixedly connected to the surface of the support frame 71. The guide rods 75 are slidably connected to the inner wall of the limiting block 72. The spring 76 is sleeved on the guide rods 75. The two guide rods 75 can guide not only the limiting block 72, but also the spring 76.

[0020] Specifically, an insert 79 is fixedly connected to the surface of the auxiliary block 78, and a slot 710 is opened on the surface of the movable frame. The insert 79 is inserted into the inner wall of the slot 710, and the insert 79 is T-shaped.

[0021] In this embodiment, the auxiliary block 78 further improves the strength and stability of the auxiliary block 78 after installation by inserting the plug 79 into the slot 710.

[0022] Specifically, a limiting component 8 is provided on the side of the bracket 2 near the heating plate 6. The limiting component 8 includes multiple stops 83 that are slidably connected to the inner wall of the bracket 2. A bidirectional screw 81 is rotatably connected to the inner wall of the bracket 2. The bidirectional screw 81 is threadedly connected to the inner wall of the stops 83. A knob 82 is fixedly connected to one end of the bidirectional screw 81.

[0023] In this embodiment: the knob 82 can be rotated to make the bidirectional screw 81 rotate. The bidirectional screw 81 can control the position of the stop 83. The stop 83 can limit the mold on which the timing belt is placed to ensure the stability of the placement.

[0024] Working principle: During operation, the timing belt is first connected end-to-end and placed in the mold. The mold is then placed on the heating plate 6. By rotating knob 82, the bidirectional screw 81 rotates, controlling the position of stop block 83. Stop block 83 limits the mold holding the timing belt, ensuring stability. Next, the pusher is pushed, moving the two limit blocks 72. Spring 76 is then stressed, and cylinder 3 operates, moving the moving plate 4 and heating plate 5, thus heating the surface. After the mold is clamped by plate 5 and heating plate 6, the pusher is released, and spring 76 drives the limit block 72 to reset. At this time, the connection operation can be performed. After connection, cylinder 3 drives moving plate 4 and heating plate 5 to reset. After moving to a certain position, auxiliary block 78 presses the roller 74 on inclined surface 73 to control the movement of limit block 72. When auxiliary block 78 moves above limit block 72, spring 76 drives limit block 72 to reset. Limit block 72 and auxiliary block 78 can reduce accidental contact, which may cause cylinder 3 to malfunction and result in crushing.
