Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical and fertilizer production technology, specifically to a device for preventing belt misalignment in pharmaceutical and fertilizer production. Background Technology

[0002] In the production and processing of pharmaceuticals and fertilizers, belt conveyor equipment is the core infrastructure for the continuous transfer of materials such as pharmaceutical and fertilizer granules and powders. Its operational stability directly affects production efficiency, material utilization rate and the cleanliness of the production environment.

[0003] Traditional belt conveyor equipment lacks anti-deviation devices, making it prone to belt deviation during transport due to factors such as fluctuations in feed rate, uneven material distribution (e.g., uneven loading), belt tension decay after long-term operation, or roller installation accuracy deviations. This frequent belt deviation becomes a key issue restricting the continuity of pesticide and fertilizer production. Therefore, to address these problems, improve the efficiency and quality of pesticide and fertilizer production, and reduce losses, this utility model has been developed. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model to solve its technical problems is: a device for preventing belt misalignment in fertilizer and pharmaceutical production, comprising: a support frame, an anti-deviation structure rotatably connected to the inner wall of the support frame, a belt body disposed outside the anti-deviation structure, the anti-deviation structure including a transmission rod, both ends of the transmission rod being rotatably connected to the inner wall of the support frame, stabilizing blocks being symmetrically slidably connected to both ends of the transmission rod, stabilizing springs being fixedly connected to the side walls of the stabilizing blocks, and a stabilizing structure being fixedly connected to the side of the stabilizing block away from the stabilizing springs.

[0005] The transmission rod passes through the stabilizing spring, and the end of the stabilizing spring away from the stabilizing block is fixedly connected to the outer wall of the support frame.

[0006] Preferably, the stabilizing structure includes a stabilizing shell, the outer wall of which is fixedly connected to the outer wall of the stabilizing block, the outer wall of which has a sliding hole, and the stabilizing shell adopts a U-shaped structure.

[0007] Preferably, the inner wall of the sliding hole is rotatably connected to the outer wall of the transmission rod, and the inner wall of the stabilizing shell is fixedly connected with a constraint structure.

[0008] Preferably, the constraint structure includes a connecting rod, the outer wall of which is fixedly connected to the inner wall of the stabilizing shell, and the connecting rods are fixedly connected to each other by a rotating rod.

[0009] Preferably, the outer wall of the rotating rod is symmetrically rotatably connected to a constraint wheel, the constraint wheel having a circular structure, and the outer wall of the constraint wheel fitting against the outer wall of the belt body.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. By setting an anti-deviation structure, when the belt tends to deviate, the reverse elastic force of the stabilizing spring can be transmitted to the belt through the stabilizing block and stabilizing shell to initially correct the deviation; the U-shaped stabilizing shell can completely wrap the edge of the belt, and with the tight contact between the constraint wheel and the belt, it further limits the belt deviation range, avoiding the problems of frequent deviation and fertilizer spillage caused by the lack of an anti-deviation structure in traditional belts.

[0012] 2. This utility model, by setting a constraint structure, connects the constraint wheel and the rotating rod in a rotatable manner. When the constraint wheel contacts the edge of the belt, it can rotate synchronously with the belt conveyor, transforming the sliding friction between the traditional sidewall and the belt into rolling friction, thereby reducing the degree of wear.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Example:

[0020] Please see Figure 1 - Figure 2This utility model provides a technical solution: a device for preventing belt misalignment in fertilizer and pesticide production, comprising: a support frame 1, an anti-deviation structure 3 rotatably connected to the inner wall of the support frame 1, a belt body 2 disposed outside the anti-deviation structure 3, and a transmission rod 31. The two ends of the transmission rod 31 are rotatably connected to the inner wall of the support frame 1, and stabilizing blocks 33 are symmetrically slidably connected to the two ends of the transmission rod 31. A stabilizing spring 32 is fixedly connected to the side wall of the stabilizing block 33, and a stabilizing structure 34 is fixedly connected to the side of the stabilizing block 33 away from the stabilizing spring 32. The transmission rod 31 passes through the stabilizing spring 32, and the end of the stabilizing spring 32 away from the stabilizing block 33 is fixedly connected to the outer wall of the support frame 1. When the belt body 2 shows a tendency to deviate during the transport of fertilizer and pesticide, the belt body 2 will generate a lateral thrust on the stabilizing structure 34 of the anti-deviation structure 3. Because the two ends of the transmission rod 31 are rotatably connected to the inner wall of the support frame 1, and the stabilizing block 33 is slidably connected to the transmission rod 31, this thrust will push the stabilizing block 33 to slide axially along the transmission rod 31. When the stabilizing block 33 slides, the stabilizing spring 32 fixed to its side wall is compressed or stretched. The stabilizing spring 32 generates a reverse elastic force due to deformation, which is transmitted to the stabilizing structure 34 through the stabilizing block 33. At the same time, the transmission rod 31 rotates normally with the movement of the belt body 2, ensuring that the fertilizer and pesticide delivery function is not affected. Driven by the stabilizing block 33, the stabilizing structure 34 applies a corrective force to the belt body 2 that is deviating, initially limiting the deviation of the belt body 2 and maintaining its centered delivery state outside the transmission rod 31, preventing fertilizer and pesticide from spilling due to belt deviation.

[0021] Please see Figure 3 The stabilizing structure 34 includes a stabilizing shell 341. The outer wall of the stabilizing shell 341 is fixedly connected to the outer wall of the stabilizing block 33. A sliding hole 342 is provided on the outer wall of the stabilizing shell 341. The stabilizing shell 341 adopts a U-shaped structure. The inner wall of the sliding hole 342 is rotatably connected to the outer wall of the transmission rod 31. A constraint structure 343 is fixedly connected to the inner wall of the stabilizing shell 341. The stabilizing shell 341 maintains a rotatable connection with the outer wall of the transmission rod 31 through the sliding hole 342 on its outer wall. This fit ensures that the stabilizing shell 341 can flexibly adjust its position along the axial direction of the transmission rod 31 with the stabilizing block 33, without interfering with the normal rotation of the transmission rod 31. Because the stabilizing shell 341 adopts a U-shaped structure, its opening fits perfectly with the edge of the belt body 2, completely covering both sides of the belt body 2 and preventing the belt body 2 from detaching from the stabilizing shell 341. Meanwhile, the constraint structure 343 fixed to the inner wall of the stabilizing shell 341 will gradually approach the belt body 2 as the stabilizing shell 341 moves. Through the contact between the constraint structure 343 and the belt body 2, the restriction on the deviation of the belt body 2 is further strengthened. Together with the elasticity of the stabilizing spring 32, a double protection is formed, which improves the stability of preventing deviation.

[0022] Please see Figure 4The constraint structure 343 includes a connecting rod 344, the outer wall of which is fixedly connected to the inner wall of the stabilizing shell 341. The connecting rods 344 are fixedly connected to each other via rotating rods 345. A constraint wheel 346 is symmetrically rotatably connected to the outer wall of the rotating rod 345. The constraint wheel 346 has a circular structure. When the stabilizing shell 341 of the stabilizing structure 34 drives the constraint structure 343 to approach the belt body 2, the constraint wheels 346 symmetrically arranged on the outer wall of the rotating rods 345 in the constraint structure 343 will make close contact with the two side edges of the belt body 2. Because the constraint wheel 346 is rotatably connected to the rotating rod 345, and the rotating rod 345 is fixed to the inner wall of the stabilizing shell 341 via the connecting rod 344, when the belt body 2 is normally conveying, the constraint wheel 346 will rotate synchronously with the movement of the belt body 2, converting the sliding friction between them into rolling friction, significantly reducing wear on the edges of the belt body 2 and extending the belt's service life.

[0023] Working principle:

[0024] During use, when the belt body 2 tends to deviate during the transport of pesticides and fertilizers, it will exert a lateral thrust on the stabilizing structure 34 of the anti-deviation structure 3. Because the two ends of the transmission rod 31 are rotatably connected to the inner wall of the support frame 1, and the stabilizing block 33 is slidably connected to the transmission rod 31, this thrust will push the stabilizing block 33 to slide axially along the transmission rod 31. When the stabilizing block 33 slides, the stabilizing spring 32 fixed to its side wall will be compressed or stretched. The stabilizing spring 32 generates a reverse elastic force due to deformation, which is transmitted to the stabilizing structure 34 through the stabilizing block 33. Simultaneously, the transmission rod 31 rotates normally with the movement of the belt body 2, ensuring that the pesticide and fertilizer transport function is not affected. Driven by the stabilizing block 33, the stabilizing structure 34 applies a corrective force to the misaligned belt body 2, initially limiting the deviation of the belt body 2 and maintaining its centered conveying state outside the transmission rod 31, preventing fertilizer and pesticide from spilling due to belt deviation. The stabilizing shell 341 is rotatably connected to the outer wall of the transmission rod 31 through a sliding hole 342 on its outer wall. This fit ensures that the stabilizing shell 341 can flexibly adjust its position along the axial direction of the transmission rod 31 with the stabilizing block 33, without interfering with the normal rotation of the transmission rod 31. Because the stabilizing shell 341 adopts a U-shaped structure, its opening fits perfectly with the edge of the belt body 2, completely covering both sides of the belt body 2 and preventing the belt body 2 from detaching from the stabilizing shell 341. Meanwhile, the constraint structure 343 fixed to the inner wall of the stabilizing shell 341 gradually approaches the belt body 2 as the stabilizing shell 341 moves. Through the contact between the constraint structure 343 and the belt body 2, the restriction on the deviation of the belt body 2 is further strengthened. Combined with the elasticity of the stabilizing spring 32, this forms double protection and improves the stability against deviation. When the stabilizing shell 341 of the stabilizing structure 34 drives the constraint structure 343 to approach the belt body 2, the constraint wheels 346 symmetrically arranged on the outer wall of the rotating rod 345 in the constraint structure 343 will make close contact with the two side edges of the belt body 2. Because the constraint wheels 346 are rotatably connected to the rotating rod 345, and the rotating rod 345 is fixed to the inner wall of the stabilizing shell 341 through the connecting rod 344, when the belt body 2 is conveying normally, the constraint wheels 346 will rotate synchronously with the movement of the belt body 2, converting the sliding friction between the two into rolling friction, greatly reducing the wear on the edge of the belt body 2 and extending the belt's service life.
