Description

Technical Field

[0001] This utility model relates to the field of synchronous belt production technology, specifically a synchronous belt production coupling machine. Background Technology

[0002] Rubber synchronous belts are a type of synchronous belt made from neoprene rubber. Neoprene rubber has good elasticity and wear resistance. In the production process of synchronous belts, an automatic splicing machine is required to splice two synchronous belt segments to form a continuous synchronous belt.

[0003] A search revealed a Chinese patent for an automatic splicing machine for synchronous belt production, publication number CN222246158U. The machine includes a splicing machine, a fixed frame fixedly connected to one side surface of the splicing machine, a bracket fixedly connected to one side surface of the fixed frame, and a motor fixedly connected to one side surface of the fixed frame.

[0004] The aforementioned device, through the configuration of controller, electrical box, main board, sensor, monitor and switch, can control the stamping machine to stop immediately when the monitor detects a foreign object, cutting off the power supply and stopping the operation of the equipment, thereby avoiding equipment damage and personal injury. When pressing the switch to start the connection, both hands are required to press the switch to start the connection machine, which enhances the protection capability.

[0005] However, although it can be started by pressing with both hands and can provide protection, its bracket support structure is relatively simple. Although the connector can fix and align the end, it may droop downwards due to insufficient support height when processing flexible or excessively long synchronous belts. At this time, it is necessary for personnel to manually support and adjust it. It is difficult to press with both hands during the process, and the repeated alignment and fixation are inefficient. Utility Model Content

[0006] The purpose of this invention is to provide a synchronous belt production coupling machine, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A synchronous belt production coupling machine includes a coupling hydraulic cylinder, a coupling machine body, and a fixed frame. The coupling machine body is divided into upper and lower parts. The lower part of the coupling machine body is installed at the front center of the fixed frame. The coupling hydraulic cylinder is installed at the front upper part of the fixed frame, and the end of the drive push rod of the coupling hydraulic cylinder is connected to the upper part of the coupling machine body. Lifting components are provided on both sides of the fixed frame.

[0009] The lifting assembly has four support rods, all of which are mounted on both sides of the fixed frame via connecting plates. Support frames are slidably mounted on the outer rings of the support rods on both sides. Support rollers are rotatably mounted on the top of the support frames. Electric telescopic rods are mounted on both sides of the support frames. Connecting rods are mounted on the push rod ends of the electric telescopic rods. A pressure plate is fixedly connected to the end of the connecting rod away from the electric telescopic rod.

[0010] Preferably, the outer ring of the supporting roller is covered with a polyurethane anti-slip sleeve, and the top surface of the supporting roller is at the same level as the top surface of the lower part of the connecting machine body.

[0011] Preferably, the outer ring of the support rod and both sides of the support frame are threaded with adjusting nuts, and the opposite sides of the adjusting nuts are in contact with the two sides of the support frame.

[0012] Preferably, the support frames have the same height and grooves are provided on the upper part of both sides of the support frames.

[0013] Preferably, the bottom end of the pressure plate is connected to a rubber pad, and the bottom surface of the rubber pad is provided with anti-slip texture.

[0014] Preferably, an electrical control box is provided at the top of the fixing frame, and the electrical control box is electrically connected to the connecting machine body and the connecting hydraulic cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, by setting up a lifting component in conjunction with the connecting machine body, can lift and fix the synchronous belt during synchronous belt connection through the cooperation of support rods, support frames, support rollers, and connecting rods. This can prevent misalignment or tensile stress concentration at the connection end caused by the synchronous belt sagging, avoid interference with the connection, and eliminate the need for personnel to lift and adjust, thereby reducing the labor intensity of personnel and facilitating the connection and support of long-distance or flexible synchronous belts.

[0017] By setting the adjusting nut and support rod to work together, the support position of the support frame can be adjusted according to the size of the timing belt to improve the flexibility of use. Furthermore, by using the connecting rod, electric telescopic rod, and pressure plate to work together, the two ends of the timing belt can be clamped before splicing to prevent accidental slippage, reduce the probability of repeated alignment and fixing, and improve splicing efficiency.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-3 A synchronous belt production coupling machine includes a coupling hydraulic cylinder 1, a coupling machine body 2, and a fixed frame 3. The coupling machine body 2 is divided into upper and lower parts. The lower part of the coupling machine body 2 is installed at the front center of the fixed frame 3. The coupling hydraulic cylinder 1 is installed at the front upper part of the fixed frame 3, and the end of the drive push rod of the coupling hydraulic cylinder 1 is connected to the upper part of the coupling machine body 2. Lifting components 5 are provided on both sides of the fixed frame 3.

[0025] See Figure 3 Furthermore, the lifting assembly 5 has four support rods 6, all of which are mounted on both sides of the fixed frame 3 via connecting plates. Support frames 7 are slidably mounted on both sides of the outer ring of the support rods 6. Support rollers 8 are rotatably mounted on the top of the support frames 7. Electric telescopic rods 9 are mounted on both sides of the support frames 7. Connecting rods 10 are mounted on the push rod ends of the electric telescopic rods 9. A pressure plate 11 is fixedly connected to the end of the connecting rod 10 away from the electric telescopic rod 9. The outer ring of the support rollers 8 is covered with a polyurethane anti-slip sleeve. The top surface of the support rollers 8 is at the same level as the lower top surface of the connecting machine body 2. An electric control box 4 is set at the top of the fixed frame 3. The electric control box 4 is electrically connected to the connecting machine body 2 and the connecting hydraulic cylinder 1.

[0026] Specifically, the two ends of the synchronous belt to be connected can be placed at the connection machine body 2, so that the synchronous belt can be heat-pressed and connected by the connection machine body 2. During connection, by placing the synchronous belt on the top surface of the support roller 8 and controlling the push rod of the electric telescopic rod 9 to retract, the pressure plate 11 can be driven to descend and clamp the synchronous belt placed on the support roller 8, so as to fix the synchronous belt before connection. There is no need for manual lifting and adjustment, thereby reducing the labor intensity of personnel. This is to provide connection support for long distances or flexible synchronous belts, prevent them from falling due to insufficient height, and reduce the impact on connection quality.

[0027] Example 2

[0028] See Figure 2 and Figure 3 Furthermore, based on Embodiment 1, the outer ring of the support rod 6 and both sides of the support frame 7 are threaded with adjusting nuts 12. The opposite sides of the adjusting nuts 12 are in contact with the two sides of the support frame 7. Several support frames 7 have the same height and grooves are provided at the upper position of both sides of the support frame 7. The bottom end of the pressure plate 11 is connected with a rubber pad, and the bottom surface of the rubber pad is provided with anti-slip texture.

[0029] Specifically, by turning the adjusting nuts 12 on both sides of the support frame 7 in sequence, the locking of the support frame 7 can be released. Then, the support frame 7 can be pushed to slide on the support rod 6 so that the lifting position of the support frame 7 can be adjusted according to the size of the timing belt. After adjustment, the adjusting nuts 12 can be turned again to clamp the support frame 7 for fixation. This method has high applicability.

[0030] In actual operation, the two ends of the synchronous belt to be connected can be placed on the connecting machine body 2, so that the synchronous belt can be heat-pressed and connected by the connecting machine body 2. During connection, by placing the synchronous belt on the top surface of the support roller 8 and controlling the push rod of the electric telescopic rod 9 to retract, the pressure plate 11 can be driven to descend and clamp the synchronous belt placed on the support roller 8, so as to fix the synchronous belt before connection. There is no need for manual lifting and adjustment, which reduces the labor intensity of personnel. This is to provide connection support for long distances or flexible synchronous belts, prevent them from falling due to insufficient height, and reduce the impact on connection quality.

[0031] By turning the adjusting nuts 12 on both sides of the support frame 7 in sequence, the locking of the support frame 7 can be released. Then, the support frame 7 can be pushed to slide on the support rod 6 to adjust the lifting position of the support frame 7 according to the size of the timing belt. After adjustment, the adjusting nuts 12 can be turned again to clamp the support frame 7 for fixation. This method has high applicability. After connection, the locking of the two support frames 7 on one side can be released. Then, the support frame 7 can be held and pulled away from the connection machine body 2 to test the connection firmness.
