Description

Technical Field

[0001] This utility model relates to the field of synchronous belt technology for automated equipment, specifically to a synchronous belt anti-deviation and correction device for automated equipment. Background Technology

[0002] Automation equipment refers to large-scale complete sets of equipment within an automation system. [Company Name] is a high-tech company specializing in the research, development, production, and sales of intelligent automatic control, digital, and networked controllers and sensors. Its numerous functional modules and comprehensive embedded solutions can meet the personalized needs of a wide range of users to the greatest extent possible.

[0003] A search revealed a Chinese patent document disclosing a synchronous belt visualization correction device [Announcement No.: CN212830856U]. A synchronous belt is wound around a synchronous pulley; two adjustable cam bearing followers are mounted on a fixed plate, symmetrically distributed on both sides of the synchronous belt. Correction of the synchronous belt's deviation is achieved by adjusting the distance between the cam bearing followers and the synchronous belt. A transparent cover is also provided on the flow channel side plate, inside which the synchronous pulley, synchronous belt, and fixed plate are located. An air inlet is located at the top of the transparent cover, and an air outlet is located at the bottom. This invention limits the synchronous belt's deviation by adjusting the distance between the two followers and the synchronous belt. When the synchronous belt deviates, it contacts the followers first, effectively preventing wear caused by the synchronous belt contacting both sides of the pulley, thus protecting the synchronous belt. It also allows for convenient observation of the internal working condition of the synchronous belt, facilitating observation and maintenance.

[0004] Automated equipment typically uses synchronous pulleys mounted on mounting plates for transmission. These pulleys are equipped with synchronous belts for transmission between devices. However, synchronous belts are prone to misalignment during transmission, affecting the transmission efficiency. The traditional solution is to install correction pulleys on both sides of the synchronous belt. However, this method exacerbates the wear of the synchronous belt and also affects the transmission efficiency. Utility Model Content

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1 - Figure 5 As shown, Example 1: An automatic equipment synchronous belt anti-deviation and correction device includes a mounting plate 1, a synchronous pulley 2 and a synchronous belt 3. The synchronous pulley 2 is hinged to one side of the mounting plate 1, and the synchronous belt 3 is wrapped around the surface of the synchronous pulley 2. A U-shaped frame 4 is fixedly connected to one side of the mounting plate 1. Two correction wheels 5 are provided on the top of the U-shaped frame 4, and a buffer mechanism is provided on one side of the correction wheels 5. The adjustment mechanism is located inside the U-shaped frame 4 and can finely adjust the position of the straightening wheel 5 according to the wear of the synchronous belt 3.

[0017] The buffer mechanism includes a housing 6 disposed on one side of the correction wheel 5. A spring groove 7 is provided inside the housing 6. A spring block 8 is disposed inside the spring groove 7. A connecting rod 9 is fixedly connected to one side of the spring block 8. Two springs 10 are fixedly connected to the other side of the spring block 8. One end of the spring 10 is fixedly connected to the inner wall of the spring groove 7. One end of the connecting rod 9 extends through to the outside of the housing 6 and is fixedly connected to a support block 11. The top of the support block 11 is rotatably connected to the bottom of the correction wheel 5 through a rotating shaft.

[0018] In this embodiment, considering that the synchronous belt 3 is prone to deviation during transmission, which affects the transmission effect, the traditional solution is to set correction wheels 5 on both sides of the synchronous belt 3. However, this setting will aggravate the wear of the synchronous belt 3 and also affect the transmission effect. Therefore, by setting a buffer mechanism, when the synchronous belt 3 is transmitted on the synchronous pulley 2, if the synchronous belt 3 deviates, it will contact the correction wheel 5. Under the influence of compression, the correction wheel 5 will drive the support block 11, connecting rod 9 and spring block 8 to move closer to the spring 10. Under the reaction force of the spring 10, it will gradually drive the spring block 8, connecting rod 9 and support block 11 to move away from the spring 10. The support block 11 will then drive the correction wheel 5 to gradually squeeze the synchronous belt 3, so that the correction wheel 5 gradually returns to the correct track, realizing the correction function, and effectively reducing the wear of the synchronous belt 3.

[0019] A protective ring 17 is fixedly connected to the surface of the correction wheel 5. The protective ring 17 is made of rubber.

[0020] In this embodiment, by setting a protective ring 17, when the timing belt 3 approaches the correction wheel 5, the protective ring 17 will first contact the timing belt 3. Through the characteristics of the rubber material of the protective ring 17, the wear of the timing belt 3 can be further reduced.

[0021] Two guide rods 18 are fixedly connected to the inner wall of the spring groove 7, and a guide hole 19 is provided on one side of the spring block 8 to cooperate with the guide rods 18.

[0022] In this embodiment, by setting guide rod 18 and guide hole 19, the movement trajectory of structures such as moving block 14 can be restricted, so that they can only move along the trajectory of guide rod 18 and guide hole 19.

[0023] Example 2: Based on Embodiment 1, in this embodiment only the buffer mechanism can use the reaction force of spring 10 to slowly correct the synchronous belt 3 and reduce the wear of synchronous belt 3. However, considering that different synchronous belts 3 have different widths, if the position of the correction wheel 5 cannot be adapted to it, it will also affect the correction effect. In this application, the adjustment mechanism includes a turning block 12 set on one side of the U-shaped frame 4. A two-way lead screw 13 is fixedly connected to one side of the turning block 12. Two moving blocks 14 are connected to the surface of the two-way lead screw 13. A sliding block 15 is fixedly connected to the top of the moving block 14. The top of the sliding block 15 is fixedly connected to the bottom of the housing 6.

[0024] In this embodiment, by setting an adjustment mechanism, when the position of the correction wheel 5 does not match the width of the timing belt 3, the double-acting screw 13 can be rotated by rotating the screwing block 12. While the double-acting screw 13 rotates, it will drive the two moving blocks 14 to move towards each other. The moving blocks 14 will drive the sliding block 15 to move. The buffer mechanism and the correction wheel 5 will move synchronously with the sliding block 15, so that the position of the correction wheel 5 matches the width of the timing belt 3, effectively improving the correction effect.

[0025] One end of the bidirectional lead screw 13 is provided with a bearing seat 16, and is rotatably connected to the inner wall of the U-shaped frame 4 through the bearing seat 16.

[0026] In this embodiment, by setting the bearing seat 16, the bidirectional lead screw 13 can be supported, and its rotation smoothness can be improved.

[0027] Working principle: When the synchronous belt 3 is driven on the synchronous pulley 2, if the synchronous belt 3 deviates, it will contact the correction wheel 5. Under the influence of compression, the correction wheel 5 will drive the support block 11, connecting rod 9 and spring block 8 to move closer to the spring 10. Under the reaction force of the spring 10, the spring block 8, connecting rod 9 and support block 11 will gradually move away from the spring 10. The support block 11 will then drive the correction wheel 5 to gradually squeeze the synchronous belt 3, so that the correction wheel 5 gradually returns to the correct track, realizing the correction function, and effectively reducing the wear of the synchronous belt 3. When the position of the straightening wheel 5 does not match the width of the timing belt 3, the double-acting screw 13 can be rotated by rotating the screwing block 12. As the double-acting screw 13 rotates, it will drive the two moving blocks 14 to move towards each other. The moving blocks 14 will drive the sliding block 15 to move. The buffer mechanism and the straightening wheel 5 will move synchronously with the sliding block 15, so that the position of the straightening wheel 5 matches the width of the timing belt 3, which effectively improves the straightening effect.
