Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts, in particular to a rubber conveyor belt with an anti-dislocation structure. Background Art

[0002] Patent No. CN219602362U discloses a white rubber conveyor belt with an anti-dislocation structure. The utility model has a reasonable structural design, so that the threaded barrel cannot rotate and can only move forward and backward with the threaded shaft.

[0003] However, for the above-mentioned existing white rubber conveyor belt with anti-misalignment structure, the staff first rotates the torsion plate, and the rotation of the torsion plate drives the threaded cylinder to move forward and backward. The movement of the threaded cylinder drives the transmission rod to move through the connecting plate, and the movement of the transmission rod drives the positioning plate to move until the inner side of the positioning plate fits with one of the front and rear sides of the conveyor belt and drives the conveyor belt to move to the appropriate position. Since this device lacks a tensioning structure for the transmission belt, the length of the transmission belt becomes longer after long-term use, and the friction between the transmission belt and the transmission roller is reduced, which is prone to slipping during operation.

[0004] In order to solve the above problems, the utility model provides a rubber conveyor belt with an anti-dislocation structure. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a rubber conveyor belt with an anti-misalignment structure to solve the technical problem in the prior art that "the staff first rotates the torsion plate, the rotation of the torsion plate drives the threaded cylinder to move forward and backward, the movement of the threaded cylinder drives the transmission rod to move through the connecting plate, the movement of the transmission rod drives the positioning plate to move, until the inner side of the positioning plate fits with one of the front and rear sides of the conveying crawler and drives the conveying crawler to move to the appropriate position. Since the device lacks a tensioning structure for the transmission crawler, the length of the transmission crawler becomes longer after long-term use, the friction between the transmission crawler and the transmission roller is reduced, and slipping is likely to occur during operation."

[0006] To achieve the above purpose, the utility model is implemented through the following technical scheme: it includes a base plate, the upper end surface of the base plate is fixedly connected with four support plates, each two plates are rotatably connected with a transmission wheel relative to the support plates, the surface of the transmission wheel is transmission-connected with a conveyor belt, the upper end surface of the base plate is fixedly connected with a support rod, the surface of the support rod is rotatably connected with a first limiting wheel, the surface of the support rod is rotatably connected with a second limiting wheel, two threaded rods are fixedly connected with symmetrical positions on the upper end surface of the base plate, the surfaces of the two threaded rods are slidably connected with connecting blocks, a tensioning shaft is rotatably connected between the two connecting blocks, the surface of the tensioning shaft is transmission-connected with the side of the conveyor belt, and the surface of the threaded rod is sleeved with a spring.

[0007] As a preferred technical solution of the utility model, a servo motor is fixedly connected to the right side surface of the support plate, and the output end of the servo motor passes through the side wall of the support plate and is fixedly connected to the center of one of the transmission wheels.

[0008] As a preferred technical solution of the present utility model, the surface of the first limiting wheel is transmission-connected to the side of the conveyor belt, and the surface of the second limiting wheel is transmission-connected to the side of the conveyor belt.

[0009] As a preferred technical solution of the utility model, the bottom end of the spring is fixedly connected to the upper end surface of the bottom plate, and the top end of the spring is fixedly connected to the lower end surface of the connecting block.

[0010] As a preferred technical solution of the utility model, a nut is threadedly connected to the surface of the threaded rod, and the lower end surface of the nut abuts against the upper end surface of the connecting block.

[0011] As a preferred technical solution of the present utility model, the size of the first limiting wheel matches the size of the support rod, and the size of the second limiting wheel matches the size of the support rod.

[0012] The utility model provides a rubber conveyor belt with an anti-dislocation structure, which has the following features:

[0013] Beneficial effects:

[0014] 1. By rotating the nut clockwise, the nut can drive the connecting block to move downward and squeeze the spring. Under the elastic force of the spring itself, the connection block and the nut can fit more stably. The connecting block drives the tensioning shaft to press against the inner wall of the conveyor belt, which can increase the friction between the conveyor belt and the transmission wheel, avoiding slipping due to the lengthening of the conveyor belt during the transmission process;

[0015] 2. The first limiting wheel and the second limiting wheel are driven by the support rod to press against both sides of the conveyor belt, so as to avoid the conveyor belt from being misaligned during the transmission process. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0023] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments:

[0024] refer to Figure 1-4 A rubber conveyor belt with an anti-dislocation structure comprises a bottom plate 1, four support plates 2 are fixedly connected to the upper end surface of the bottom plate 1, a transmission wheel 3 is rotatably connected between every two relative support plates 2, a conveyor belt 4 is transmission-connected on the surface of the transmission wheel 3, a support rod 5 is fixedly connected to the upper end surface of the bottom plate 1, a first limiting wheel 6 is rotationally connected to the surface of the support rod 5, a second limiting wheel 7 is rotationally connected to the surface of the support rod 5, two threaded rods 12 are fixedly connected to the symmetrical positions of the upper end surface of the bottom plate 1, a connecting block 9 is slidably connected to the surfaces of the two threaded rods 12, a tensioning shaft 10 is rotationally connected between the two connecting blocks 9, the surface of the tensioning shaft 10 is transmission-connected to the side of the conveyor belt 4, and a spring 11 is sleeved on the surface of the threaded rod 12.

[0025] By providing the spring 11 , the elastic force of the spring 11 itself can make the fitting between the connecting block 9 and the nut 13 more stable.

[0026] Furthermore, a servo motor 8 is fixedly connected to the right side surface of the support plate 2 , and an output end of the servo motor 8 passes through the side wall of the support plate 2 and is fixedly connected to the center of one of the transmission wheels 3 .

[0027] By providing the servo motor 8 , the servo motor 8 can drive the conveyor belt 4 to transport the articles via the transmission wheel 3 .

[0028] Furthermore, the surface of the first limiting wheel 6 is in transmission connection with the side of the conveyor belt 4 , and the surface of the second limiting wheel 7 is in transmission connection with the side of the conveyor belt 4 .

[0029] Furthermore, the bottom end of the spring 11 is fixedly connected to the upper end surface of the bottom plate 1 , and the top end of the spring 11 is fixedly connected to the lower end surface of the connecting block 9 .

[0030] Furthermore, a nut 13 is threadedly connected to the surface of the threaded rod 12 , and a lower end surface of the nut 13 abuts against an upper end surface of the connecting block 9 .

[0031] By setting the nut 13, the nut 13 can be rotated clockwise to drive the connecting block 9 to move downward, and the connecting block 9 drives the tensioning shaft 10 to tension the conveyor belt 4.

[0032] Furthermore, the size of the first limiting wheel 6 matches the size of the support rod 5 , and the size of the second limiting wheel 7 matches the size of the support rod 5 .

[0033] The working principle of the utility model is as follows: during operation, by arranging support rods 5 on both sides of the conveyor belt 4, and making the first limiting wheel 6 and the second limiting wheel 7 on the support rod 5 abut against both sides of the conveyor belt 4, when the conveyor belt 4 moves, the first limiting wheel 6 and the second limiting wheel 7 can be respectively driven to rotate in opposite directions, and the first limiting wheel 6 and the second limiting wheel 7 can prevent the conveyor belt 4 from being misaligned. After long-term use, the staff can turn the nut 13 in the clockwise direction and drive the connecting block 9 to move downward. The connecting block 9 drives the tensioning shaft 10 to abut against the inner side of the conveyor belt 4, so as to tension the conveyor belt 4 and avoid slipping.

[0034] Compared with the prior art, the friction between the conveyor belt 4 and the transmission wheel 3 can be increased, thereby avoiding slipping due to the lengthening of the conveyor belt 4 during the transmission process.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
