Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts, in particular to an anti-tearing device added to a workshop conveyor belt. Background Art

[0002] In modern industrial production, workshop conveyor belts play a crucial role. They carry the transmission tasks of raw materials, semi-finished products and finished products, ensuring the smoothness and efficiency of the production process. The workshop environment is complex and changeable. Especially in a humid or moist environment, the conveyor belt is prone to problems such as slipping and deviation.

[0003] Traditional workshop conveyor belts often lack effective monitoring and correction mechanisms. When the belt slips or deviates, it often cannot be detected and processed in time, which will lead to increased friction between the belt and the roller or bracket, and even cause serious failures such as belt tearing. This will not only cause production interruption, increase maintenance costs, but also pose a threat to production safety. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the prior art, and an anti-tearing device is added to the workshop conveyor belt.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An anti-tearing device is added to the workshop conveyor belt, including a conveyor main body, a support, a detection roller and a deviation correction roller.

[0007] The conveyor main body includes a frame, driving rollers and a belt. The driving rollers are distributed above and below the frame, and the belt is transmissionally arranged between several driving rollers; the support is fixedly arranged above the frame and is arranged at intervals along the length direction of the frame, and a driving component is arranged between several supports; the detection roller is located above the support, and the detection rollers are symmetrically distributed along the length of the belt and contact the belt; the deviation correction roller is located above the support, and the deviation correction rollers are symmetrically distributed along the length direction of the belt and symmetrically distributed with the detection rollers.

[0008] Preferably, chutes are opened on both the front and rear sides of the top of the support, sliders are arranged inside the chutes, springs are fixedly connected between the sliders and the inner walls of the chutes, position sensors corresponding to the sliders are fixedly installed on the inner walls of the sliders, a sliding support is fixedly connected to the top of the sliders, and the detection roller is rotatably arranged inside the sliding support.

[0009] Preferably, an accommodation cavity is formed inside the support, a bidirectional screw rotatably connected to the support is arranged inside the accommodation cavity, two nuts are threadedly connected to the outer wall of the bidirectional screw at intervals along its length direction, a support base is fixedly connected to the outside of the two nuts, an adjustment bracket is fixedly connected to the top of the support base, and the deviation rectifying roller is rotatably arranged inside the adjustment bracket.

[0010] Preferably, the driving assembly includes a servo motor, the servo motor is fixedly installed on the back of the rightmost support, the output shaft of the servo motor is connected to the bidirectional screw inside the support, a sprocket is fixedly sleeved on one end of the front of each bidirectional screw, and a chain is arranged in a transmission manner between the sprockets.

[0011] Preferably, the cross-section of the sliding groove is cross-shaped, and the shape of the slider is adapted to the sliding groove and is slidably matched with the sliding groove.

[0012] Preferably, the cross-section of the accommodation cavity is concave-shaped, and the shape of the support base is adapted to the accommodation cavity and is slidably matched with the accommodation cavity.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In the present utility model, real-time monitoring of the position of the belt can be realized. Once the belt shows a tendency to deviate, it can be quickly captured by the detection roller, and a signal is transmitted through the position sensor, ensuring the timeliness of problem discovery.

[0015] 2. In the present utility model, the bidirectional screw is driven to rotate by the servo motor, so that the two support bases can move relative to each other, thereby driving the deviation rectifying roller to contact the deviated belt and pushing it back to the middle position of the driving roller, ensuring that the belt can quickly return to the correct running track, avoiding the belt from slipping and deviating, which is likely to cause the belt to tear, and guaranteeing the continuity and safety of the workshop production.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] The conveyor body 100 includes a frame 101, a driving roller 102 and a belt 103. The driving roller 102 is distributed above and below the frame 101, and the belt 103 is transmitted between a plurality of driving rollers; a support 200 is fixedly arranged above the frame 101 and spaced along the length direction of the frame 101, and a driving assembly 300 is arranged between the plurality of supports 200; a detection roller 201 is located above the support 200, and the detection roller 201 is symmetrically distributed along the length of the belt 103 and contacts the belt 103; a deviation correction roller 202 is located above the support 200, and the deviation correction roller 202 is symmetrically distributed along the length direction of the belt 103 and the detection roller 201.

[0025] In this embodiment, a slide groove 203 is provided on both the front and rear sides of the top of the support 200, a slider 204 is provided inside the slide groove 203, a spring 205 is fixedly connected between the slider 204 and the inner wall of the slide groove 203, a position sensor 206 corresponding to the slider 204 is fixedly installed on the inner wall of the slider 204, a sliding bracket 207 is fixedly connected to the top of the slider 204, and the rotation detection roller 201 is arranged on the inner side of the sliding bracket 207.

[0026] In this embodiment, an accommodation cavity 208 is formed inside the support 200. A bidirectional screw 209 rotatably connected to the support 200 is arranged inside the accommodation cavity 208. Two nuts 210 are threadedly connected to the outer wall of the bidirectional screw 209 and are arranged at intervals along its length direction. A support base 211 is fixedly connected to the outer sides of the two nuts 210. An adjustment bracket 212 is fixedly connected to the top of the support base 211. The deviation-correcting roller 202 is rotatably arranged inside the adjustment bracket 212.

[0027] In this embodiment, the driving assembly 300 includes a servo motor 301. The servo motor 301 is fixedly installed on the back of the rightmost support 200. The output shaft of the servo motor 301 is connected to the bidirectional screw 209 inside this support 200. A sprocket 302 is fixedly sleeved on one end of the front side of each bidirectional screw 209. A chain 303 is drivingly arranged between the sprockets 302. The servo motor 301 can drive the bidirectional screw 209 to drive one of the sprockets 302 to rotate, and this sprocket 302 drives the remaining sprockets 302 to rotate through the chain 303, realizing the synchronous rotation of multiple bidirectional screws 209.

[0028] In this embodiment, the cross-section of the chute 203 is cross-shaped, and the shape of the slider 204 is adapted to the chute 203 and is in sliding fit with the chute 203; with the cooperation of the slider 204 and the chute 203, the slider 204 can only move in a straight line to avoid deviation.

[0029] In this embodiment, the cross-section of the accommodation cavity 208 is concave-shaped, and the shape of the support base 211 is adapted to the accommodation cavity 208 and is in sliding fit with the accommodation cavity 208; with the cooperation of the support base 211 and the accommodation cavity 208, the support base 211 can only move in a straight line to avoid deviation.

[0030] Usage method and working principle of this device:

[0031] When this device is in use, first, the range threshold of the distance sensed by the position sensor 206 is adjusted. Moreover, the position sensor 206 and the servo motor 301 are connected through a PLC controller (not shown). The PLC controller receives the signal of the position sensor 206 and controls the operation of the servo motor 301. This is prior art that has been publicly disclosed and will not be elaborated here.

[0032] The detection roller 201 contacts the belt 103. When the belt 103 is prone to slipping and deviation when wet, the belt 103 will contact and push the detection roller 201 in the deviation direction. The detection roller 201 slides along the chute 203 through the slider 204 of the sliding support 207 and compresses the spring 205. When the position sensor 206 detects that the distance from the slider 204 is not within the threshold, the PLC controller can be used to drive the servo motor 301 to work. The servo motor 301 drives one of the bidirectional screws 209 to rotate, and the sprocket 302 at the end of the bidirectional screw 209 causes the chain 303 to drive the remaining bidirectional screws 209 to rotate synchronously. When the bidirectional screw 209 rotates, the two nuts 210 drive the two support seats 211 to move relatively. The support seats 211 drive the deviation correction roller 202 in the adjustment bracket 212 thereon to move, so as to contact the belt 103 and push the belt 103 back to the middle position of the driving roller 102. After the position sensor 206 detects that the distance from the slider 204 has returned to the set threshold, the servo motor 301 reverses to reset the deviation correction roller 202.

[0033] In summary, by timely detecting the position of the belt 103, it is possible to sensitively detect the deviation when the belt 103 slips and deviates, and timely correct the belt 103, pre-controlling the tearing of the belt 103 caused by the slipping and deviation of the belt 103.

[0034] The above description is only a preferred embodiment of the present invention, and is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
