When the belt conveyor generates tension fluctuations when in use, start motor 2, and the output shaft of motor 2 will cause the rotating rod 1 to rotate, and the rotation of the rotating rod 1 will drive the two-way threaded rod to rotate, and the rotation of the two-way threaded rod will cause the two threaded sleeves to move in opposite directions, and the movement of the two threaded sleeves will drive the long block to move, and the movement of the long block will push the T-shaped block to move on the inner wall of the track groove of the track block through the hinge rod 1. At the same time, the movement of the T-shaped block will drive the pressure plate to move downward, so that the pressure plate suppresses the belt body that generates tension fluctuations.

Through the setting of the above structure, the pressure plate 29 suppresses the belt body 10 that generates tension fluctuations, avoiding the problem of twisting, tearing or even breaking of the belt body 10 during tension fluctuations, thereby ensuring the smooth operation of the production line.

[0029] The top of the threaded sleeve 25 is fixedly connected to an elastic telescopic rod 211, and the telescopic end of the elastic telescopic rod 211 is fixedly connected to a V-shaped rod 212. The top of the V-shaped rod 212 contacts the bottom of the belt body 10.

[0030] The top of the pressure plate 29 is provided with an anti-damage device 3 for preventing hard debris from scratching or damaging the belt surface. The anti-damage device 3 includes two notches 31. The two notches 31 are opened on the top of the pressure plate 29. The inner walls of the two notches 31 are rotatably connected to the second rotating rod 32. The two second rotating rods 32 are staggered. The circumferential surface of the second rotating rod 32 is fixedly connected to a plurality of rotating wheels 33. One end of the second rotating rod 32 is fixedly connected to the first rotating wheel 34. The outer wall of the first rotating wheel 34 is rotatably connected to a connecting rod 35.

[0031] The top of the moving block 312 is fixedly connected to an L-shaped block 315, and the side of the L-shaped block 315 is fixedly connected to a push plate 316. The side of the push plate 316 contacts the side of the belt body 10. Through the setting of the above structure, the push plate 316 will always be located on the side below the belt body 10, thereby avoiding the problem of the belt body 10 shaking when the cleaning roller 39 moves for cleaning.

[0032] During use, when the belt conveyor generates tension fluctuations during use, the motor 22 is started, and the output shaft of the motor 22 causes the rotating rod 1 23 to rotate. The rotation of the rotating rod 1 23 drives the bidirectional threaded rod 24 to rotate. The rotation of the bidirectional threaded rod 24 causes the two threaded sleeves 25 to move in opposite directions. The movement of the two threaded sleeves 25 drives the long block 26 to move. The movement of the long block 26 pushes the T-shaped block 28 to move on the inner wall of the track groove of the track block 210 through the hinge rod 1 27. At the same time, the movement of the T-shaped block 28 drives the pressing plate 29 to move downward, thereby The pressing plate 29 suppresses the belt body 10 that produces tension fluctuations, thereby avoiding the problem of twisting, tearing or even breaking of the belt body 10 during tension fluctuations, thereby ensuring the smooth operation of the production line; at the same time, the movement of the threaded sleeve 25 will drive the elastic telescopic rod 211 to move, and the movement of the elastic telescopic rod 211 will drive the V-shaped rod 212 to move.

[0033] The surface of the belt body 10 may be stuck by hard debris, which may cause damage to the belt body 10. Therefore, when the belt body 10 moves, the belt body 10 drives the rotating wheel 33 to rotate, and the rotation of the rotating wheel 33 drives the rotating rod 2 32 to rotate, and the rotation of the rotating rod 2 32 drives the rotating wheel 1 34 to rotate, and the rotation of the rotating wheel 1 34 drives the rotating wheel 2 36 to rotate through the track 37, and the rotation of the rotating wheel 2 36 drives the short rod 38 to rotate, and the rotation of the short rod 38 drives the cleaning roller 39 to move, and the movement of the cleaning roller 39 drives the semicircular block 310 to move, and the movement of the semicircular block 310 will conflict with the conflicting block 314, so that the cleaning roller 39 squeezes the spring, and when the movement of the semicircular block 310 does not conflict with the conflicting block 314 When the belt body 10 is cleaned, the spring 32 will drive the cleaning roller 39 and the semicircular block 310 to reset by its own elastic force, and the cleaning roller 39 will achieve the effect of reciprocating motion, so that the cleaning roller 39 can more conveniently clean the hard debris on the surface of the belt body 10, avoiding the problem of scratching or damaging the surface of the belt body 10; because the two rotating rods 32 are staggered, the rotating rod 32 in one anti-damage device 3 is located above the push plate 316 in the other anti-damage device 3, so when the pressure plate 29 pushes the belt body 10, the rotating rod 32 will also push the push plate 316 to move, thereby ensuring that the push plate 316 will always be located on the side below the belt body 10, thereby avoiding the problem of the belt body 10 shaking when the cleaning roller 39 moves for cleaning.

[0034] See also Figure 1-10On the basis of the above-mentioned embodiment, in another embodiment of the present invention, an anti-deviation device 4 is provided on the top of the baffle 5 to prevent the belt body 10 from deviating during operation.

[0035] The anti-deviation device 4 includes a limiting block 41, the bottom of which is fixedly connected to the top of the baffle 5, and two long rods 42 are inserted through the side of the limiting block 41 for sliding, and one end of the two long rods 42 is fixedly connected to the same contact plate 43, and a spring is arranged between the contact plate 43 and the limiting block 41, and the side of the contact plate 43 contacts the side of the belt body 10. Through the arrangement of the above structure, the springs on both sides above the belt body 10 will drive the contact plate 43 to contact the two sides above the belt body 10 through their own elastic force, thereby preventing the belt body 10 from deviating during operation.

[0036] An elastic hinge rod 46 is hinged at the eccentric part of the side of the rotating wheel 2 36, and a U-shaped block 45 is hinged at one end of the elastic hinge rod 46 away from the rotating wheel 2 36. A plurality of scraper blocks 44 are fixedly connected to the upper side of the U-shaped block 45, and the sides of the plurality of scraper blocks 44 are in contact with the sides of the belt body 10. Through the arrangement of the above structure, the back and forth movement of the scraper blocks 44 will scrape off the debris adhered to the side of the belt body 10, thereby avoiding the problem that the adhesion from the belt body 10 is adhered to the side of the resistance plate 43 again, resulting in more and more adhesion on the side of the resistance plate 43, causing the adhesion to move up or down along the side of the resistance plate 43, and finally move to the surface of the belt body 10.

[0037] During use, when the belt body 10 is running, the springs on both sides above the belt body 10 will drive the resistance plate 43 to resist the two sides above the belt body 10 through their own elastic force, thereby preventing the belt body 10 from deviating during operation; at the same time, the rotation of the second rotating wheel 36 will push the U-shaped block 45 to move back and forth through the elastic hinge rod 46, and the back and forth movement of the U-shaped block 45 will drive the scraper block 44 to move back and forth. The back and forth movement of the scraper block 44 will scrape off the debris adhered to the side of the belt body 10, thereby avoiding the problem that the adhesion from the belt body 10 is adhered to the side of the resistance plate 43 again, resulting in more and more adhesion on the side of the resistance plate 43, causing the adhesion to move up or down along the side of the resistance plate 43, and finally move to the surface of the belt body 10.
