[0015] 2. The present invention drives the driving roller to rotate by the driving motor, and with the cooperation of the synchronous belt and the driven pulley, it can drive the cleaning roller brush in the cleaning seat to rotate, so as to clean the surface of the conveyor belt after conveying the goods, thereby ensuring the conveying cleanliness of the conveyor belt surface and avoiding the conveyor belt to be stuck with the residual goods after conveying, which will increase the wear of the conveyor belt and may even scratch the conveyor belt, thus affecting its service life. In addition, the accumulation of residual goods on the conveyor belt may cause the conveyor belt to deviate and affect the normal operation of the conveyor belt. If the residual goods on the conveyor belt cannot be effectively removed, the traction force and power distribution of the two rollers may be uneven, resulting in motor overload. At the same time, the accumulation of residual goods on the roller body may cause the equipment to operate inflexibly, affect the conveying efficiency, and may even cause equipment failure, and generate greater noise when the equipment is running, affecting the physical and mental health of the staff, and further may affect the production efficiency and increase the operating cost of the enterprise.

[0022] For example, see Figure 1-Figure 4 As shown, the present invention provides a technical solution: a thermoformed roller dedicated tube and a belt conveyor device, including a roller body 3 in which a tube body and a bearing seat are thermoformed as one body, and also includes: A support shaft 302 is located inside the roller body 3, and a sealing sleeve 304, a limiting sleeve 303 and a bearing 301 are sequentially arranged between the left and right ends of the outer surface of the support shaft 302 and the two ends inside the roller body 3 from the outside to the inside; Both end faces of the roller body 3 are large arc structures.

[0023] Positioning grooves are provided on both the front and rear sides of the left and right ends of the support shaft 302 .

[0024] This technical solution: the roller body 3 is processed by a hot forming process, and the tube body and the bearing seat are integrally hot formed, a non-welded structure, which can effectively eliminate the deformation caused by welding and improve the straightness and roundness of the tube body. After integral forming, the bearing seat is machined, which can effectively improve the coaxiality of the tube body surface and the bearing 301 and reduce the diameter runout. At the same time, the integrally formed tube body has a large arc structure on the end face, which can effectively reduce the wear of the roller edge on the belt and increase the service life of the belt. This type of tube body can reduce the distance between the bearing 301 and the end face of the tube body, which can effectively reduce the torque of the roller during operation, improve the operating environment of the bearing 301, and increase the service life of the bearing 301. The structure of the tube body and the bearing seat is changed to directly eliminate the internal depression of the punch seat in the welding structure and the problem of material storage during operation. With the assistance of the sealing sleeve 304, it helps to enhance the roller sealing structure and better protect the bearing 301.

[0025] A belt conveyor device comprises a conveyor seat 1 in which a plurality of roller bodies 3 are equidistantly arranged, and further comprises: A driving seat 2 is fixedly mounted at the middle end of the bottom of the conveying seat 1, and a driving roller 204 is movably connected to the middle end of the inner side of the driving seat 2 through a bearing, a driving pulley 205 is fixedly mounted on the right side of the driving roller 204, and a guide roller 207 is arranged at the upper end of the inner side of the driving seat 2 in the front and rear directions of the driving roller 204, and a driving motor 206 is fixedly mounted on the rear side of the driving seat 2, and the output end of the driving motor 206 is fixedly connected to the rear side of the driving roller 204; A conveyor belt 5 is sleeved on the outer side of the roller body 3 and the driving roller 204, and the conveyor belt 5 is in contact with the outer surface of the guide roller 207; A cleaning seat 4 is fixedly mounted at the rear end of the bottom of the conveying seat 1, and a cleaning roller brush 202 is movably connected to the front end of the inner side of the cleaning seat 4 through a bearing. The right end of the cleaning roller brush 202 passes through the cleaning seat 4 and is placed on the right side thereof. A driven pulley 203 is fixedly mounted on the right end of the cleaning roller brush 202, and a synchronous belt 201 is sleeved on the outer sides of the driving pulley 205 and the driven pulley 203.

[0026] The technical solution of the present invention is that when the driving motor 206 drives the driving roller 204 to rotate, and with the assistance of the guide roller 207, the conveyor belt 5 sleeved on the outer side of the roller body 3 and the driving roller 204 can be driven, thereby ensuring the conveying work of the belt conveying equipment of the present invention, and with the use of multiple roller bodies 3, the radial jump of the traditional belt conveying equipment and the wear of the belt by the edge of the traditional roller are reduced, which facilitates the use of the equipment, improves its own performance, reduces the frequency of overhaul and maintenance, and saves the use cost. When the driving roller 204 rotates, it will drive the driving pulley 205 to rotate, and with the cooperation of the synchronous belt 201 and the driven pulley 203, it can drive the cleaning roller brush 202 in the cleaning seat 4 to rotate, thereby being able to clean the conveyor belt after conveying the goods. The surface of the conveyor belt 5 is cleaned to ensure the conveying cleanliness of the surface of the conveyor belt 5. The residual goods on the conveyor belt 5 after conveying will increase the wear of the conveyor belt 5 and may even scratch the conveyor belt 5, affecting its service life. In addition, the accumulation of residual goods on the conveyor belt 5 may cause the conveyor belt 5 to deviate and affect the normal operation of the conveyor belt 5. If the residual goods on the conveyor belt 5 cannot be effectively removed, the traction and power distribution of the two rollers may be uneven, causing the motor to overload. At the same time, the residual goods are accumulated on the roller body 3, which will cause the equipment to operate inflexibly, affect the conveying efficiency, and may even cause equipment failure, and generate greater noise when the equipment is running, affecting the physical and mental health of the staff, and further may affect the production efficiency and increase the operating costs of the enterprise.

[0027] Embodiment 2, based on embodiment 1, the present invention is as follows Figure 1-Figure 4As shown, a support frame 103 is fixedly installed at the bottom of the conveying seat 1, a steering wheel 101 is fixedly installed at the front end of the bottom of the support frame 103, and a moving wheel 102 is fixedly installed at the rear end of the bottom of the support frame 103. The left and right ends of the inner side of the conveying seat 1 are provided with multiple positioning grooves 104 that are equidistantly distributed and adapted to the left and right ends of the support shaft 302.

[0028] This technical solution: through the setting of the steering wheel 101 and the moving wheel 102, it is convenient to move the position of the belt conveyor equipment, and the flexibility of the equipment when in use is improved. Through the setting of the positioning groove 104, it can cooperate with the support shaft 302 with positioning grooves on the left and right ends, thereby ensuring the installation and smooth operation of the roller body 3.

[0029] Embodiment 3, based on embodiment 1, the present invention is as follows Figure 1-Figure 4 As shown, an arc-shaped groove 401 is provided on the inner surface of the rear end of the cleaning seat 4, an arc-shaped guide rod 409 is fixedly connected to the inner side of the arc-shaped groove 401, springs 406 are sleeved at the upper and lower ends of the arc-shaped guide rod 409, an arc-shaped movable sleeve 405 sliding on the outer surface of the arc-shaped guide rod 409 is fixedly connected between the two springs 406, an adjustment rod 402 is movably connected to the rear end of the inner side of the cleaning seat 4, an L-shaped connecting block 404 is fixedly connected between the left and right ends of the adjustment rod 402 and the arc-shaped movable sleeve 405, and the arc-shaped movable sleeve 405 is adapted to the arc groove 401, and the arc movable sleeve 405 slides on the inner side of the arc groove 401, the outer surface of the adjusting rod 402 is sleeved with an adjusting sleeve 403, the left and right ends of the bottom of the adjusting sleeve 403 are threadedly connected with adjusting bolts 408, and one end of the adjusting bolt 408 abuts against the outer surface of the adjusting rod 402, the outer surface of the adjusting sleeve 403 is fixedly connected with an arc scraper 407, the material of the arc scraper 407 is ultra-high molecular weight polyethylene, and the tip of the arc scraper 407 fits with the surface of the conveyor belt 5.

[0030] The technical solution of the present invention is that when the adjusting rod 402 is movably arranged at the rear end of the cleaning seat 4, the adjusting sleeve 403 can be sleeved on the outer side of the adjusting rod 402. Then, according to the running condition of the conveyor belt 5, the fitting angle between the tip of the arc scraper 407 and the surface of the conveyor belt 5 is adjusted. After the adjustment is completed, the adjusting bolt 408 is tightened to abut against the outer surface of the adjusting rod 402, so that the position of the adjusting sleeve 403 can be limited. When the belt conveyor equipment is working, the arc scraper 407 with the tip fitting against the surface of the conveyor belt 5 can scrape the surface of the conveyor belt 5. Due to the objects remaining on the conveyed goods, with the assistance of the adjusting bolt 408, when the adjusting sleeve 403 drives the adjusting rod 402 to move, the adjusting rod 402 can drive the arc-shaped movable sleeve 405 to slide on the outer surface of the arc-shaped guide rod 409 through the L-shaped connecting block 404, and then when the balance of the spring 406 is broken, the vibration caused by scraping the residual objects can be buffered, and the tip of the arc-shaped scraper 407 can always fit with the surface of the conveyor belt 5, thereby ensuring the scraping effect of the residual goods on the surface of the conveyor belt 5, which is more convenient for people to use.
