Description

Technical Field

[0001] The utility model belongs to the technical field of conveyor belts, and particularly relates to a device for adjusting the parallelism of belt operation. Background Art

[0002] Conveyor belts are belts, plastic mesh belts, metal mesh belts, and other devices that carry and transport goods. They are widely used in agriculture, mining, transportation, and food industries. They enable continuous, efficient, and high-angle transportation. They are easy to use, maintain, and provide low freight costs. However, they are the most expensive and least durable component of a conveyor.

[0003] Conveyor belts often systematically deviate during operation. Even with a corrective device installed, this cannot guarantee the parallelism of the conveyor belt's running direction with the frame. This causes the conveyor belt's mesh / belt to rub against the transmission mechanism. This phenomenon is particularly common with longer conveyor belts, which increase the belt's deviation.

[0004] Conveyor belts in the industry inevitably deviate during operation. To prevent this, guide devices (such as various sidewalls) or automatic deviation-correcting devices are generally used. The use of guide devices such as sidewalls will inevitably lead to accelerated wear and tear of the conveyor belt. Automatic deviation-correcting devices can ensure stable operation within a certain range at one end of the conveyor belt, but because they cannot guarantee the parallelism of the conveyor belt and the frame, the conveyor belt at the other end may deviate from the operating center and even rub against the frame, resulting in adverse consequences. The longer the conveyor belt, the more obvious this undesirable phenomenon becomes, and it may even cause damage to the conveyor belt and prevent the equipment from functioning properly. Utility Model Content

[0007] The cam is secured to the chassis and has a bottom surface, the cam being secured to the chassis by a spring, and the cam being secured to the chassis by a spring.

[0008] As an optimal technical solution, the adjustment mechanism includes two groups of L-shaped fixing brackets fixedly installed on the side of the roller cantilever beam by bolts, an H-shaped bracket is installed between the two groups of L-shaped fixing brackets, both ends of the H-shaped bracket are rotatably connected to the tensioning roller, and a plurality of positioning holes are opened on the side of the H-shaped bracket, and a positioning pin is provided on one of the L-shaped fixing brackets.

[0009] As an optimal technical solution, the cantilever beam pull rod is set in an L shape, and the cantilever beam pull rod includes a fixed plate A and a fixed plate B connected as one piece. One end of the fixed plate A is provided with an inward-bent folded edge A, and a U-shaped hole is provided on the folded edge A. The other end of the fixed plate B is provided with an outward-bent folded edge B, and a mounting hole is provided on the folded edge B. The fixed plate B is also provided with a waist hole.

[0014] First, the present application realizes precise adjustment of the parallelism of the conveyor belt through the adjustment mechanism and the cantilever beam pull rod. The H-shaped bracket and tensioning roller in the adjustment mechanism can not only flexibly adjust the tension of the conveyor belt, but also adapt to different work requirements. The L-shaped design of the cantilever beam pull rod, combined with the structure of the fixed plate A and the fixed plate B, makes the adjustment more flexible and precise. In particular, by using the combination of the adjusting bolts and nuts and the fixing bolts, the horizontality of the outer end of the roller cantilever beam can be accurately adjusted, effectively eliminating the downward force caused by the tension of the conveyor belt and the downward inclination of the H-shaped bracket. It not only solves the problem of deviation in the traditional conveyor belt system, but also significantly improves the operational stability and efficiency of the conveyor belt, greatly improves the adaptability and reliability of the device, and effectively extends the service life of the conveyor belt.

DETAILED DESCRIPTION

[0025] The utility model of this application is further described in detail below with reference to the accompanying drawings and specific embodiments. In order to clearly and completely describe the technical solution, the following embodiments are selected for illustration; other embodiments obtained based on the content recorded in this application without creative work are all within the scope of protection of this utility model.

[0026] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", "top / bottom", etc., or the like, are based on the terms or the like as shown in the accompanying drawings. They are only for the purpose of clearly describing the present embodiment, and do not indicate or imply that the device or element referred to must have a specific orientation. Therefore, they should not be understood as limiting the present application.

[0027] The following is combined with Figure 1-8 This application is described in further detail.

[0028] In conveyor belt systems, systematic deviation often occurs during operation. This phenomenon is particularly noticeable in long-distance conveying equipment, where the deviation of the conveyor belt increases with the length of the equipment. Although various solutions have been adopted in existing technologies, they all have certain limitations:

[0029] Guide devices (such as various sidewalls): Although they can prevent the conveyor belt from deviating to a certain extent, they will cause the conveyor belt to wear faster and shorten its service life.

[0030] Automatic deviation-correcting devices ensure that the conveyor belt runs stably within a specific range at one end, but they cannot guarantee the overall parallelism between the conveyor belt and the frame. This can cause the conveyor belt to deviate from the running center at the other end, or even cause friction with the frame, causing damage to the conveyor belt.

[0031] Even if a correction device is installed, it is impossible to completely guarantee the parallelism of the conveyor belt's running direction with the frame, and there will be friction and wear between the conveyor belt's mesh belt or belt and the transmission mechanism.

[0032] In order to solve the above problems, the present application discloses a device for adjusting the parallelism of belt operation, including a frame 1 and a conveyor belt 2 installed on the frame 1. In order to protect the conveyor belt and maintain a constant working temperature, an upper insulation cover 3 and a lower insulation cover 4 are respectively provided on the upper and lower sides of the conveyor belt 2. The frame 1 is the foundation of the entire device. The frame 1 includes an integrally connected fixing part 11 and a supporting part 12. Support feet 13 are installed on both sides below the fixing part 11 to ensure that the entire device is firmly installed on the ground. The supporting part 12 is connected to a position above the fixing part 11 near the outside. A supporting cross plate 14 and a roller cantilever beam 15 are fixedly installed on the side of the supporting part 12. The outer end of the roller cantilever beam 15 is connected to a cantilever beam pull rod 16 by bolts. The upper end of the cantilever beam pull rod 16 is connected to the supporting cross plate 14 by bolts. An adjusting mechanism 5 for adjusting the tension of the conveyor belt is fixedly installed on the roller cantilever beam 15 by bolts.

[0033] The adjustment mechanism 5 includes two groups of L-shaped fixing brackets 51 fixed on the side of the roller cantilever beam 15 by bolts, and an H-shaped bracket 52 is installed between the two groups of L-shaped fixing brackets 51. Both ends of the H-shaped bracket 52 are rotatably connected to the tensioning roller 53. A plurality of positioning holes 54 are opened on the side of the H-shaped bracket 52, and a positioning pin 55 is provided on one of the L-shaped fixing brackets 51.

[0034] The cantilever beam pull rod 16 is arranged in an L shape, and the cantilever beam pull rod 16 includes a fixed plate A161 and a fixed plate B162 that are integrally connected. One end of the fixed plate A161 is provided with an inward-bent folded edge A163, and a U-shaped hole 164 is provided on the folded edge A163. The other end of the fixed plate B162 is provided with an outward-bent folded edge B165, and a mounting hole 166 is provided on the folded edge B165. The fixed plate B162 is also provided with a waist hole 167.

[0035] The lower surface of the outer end of the roller cantilever beam 15 abuts against the top of the folded edge B165, and a bolt hole A is provided on the lower side of the outer end of the roller cantilever beam 15. A bolt hole B is provided on the outer side of the roller cantilever beam 15. The mounting hole 166 on the folded edge B165 and the bolt hole on the lower side of the roller cantilever beam 15 are connected by an adjusting bolt and nut 17. The adjusting bolt and nut 17 is used to adjust the horizontality of the outer end of the roller cantilever beam 15. The bolt hole B on the roller cantilever beam 15 and the waist hole 167 of the fixing plate B162 are fixed by fixing bolts.

[0036] The folded edge A163 and the supporting transverse plate 14 are fixed by hexagonal bolts.

[0037] When in use, start the conveyor belt, make the conveyor belt 2 reach the normal tension state, and observe the downward pressure of the conveyor belt 2 on the roller cantilever beam 15;

[0038] When the conveyor belt is subjected to force, the outer end of the adjusting mechanism 5 for adjusting the tension of the conveyor belt will also tilt downward. When the outer side of the H-shaped bracket 52 tilts downward, the roller cantilever beam 15 will inevitably be subjected to a downward component of force, causing the outer end of the roller cantilever beam 15 to tend to deform downward.

[0039] Find the adjusting bolt and nut 17 and the fixing bolt, first loosen the fixing bolt, then rotate the adjusting bolt and nut 17 clockwise to move the outer end of the roller cantilever beam 15 upward. The goal of the adjustment is to offset the downward pressure caused by the tension of the conveyor belt and the downward tilt of the H-shaped bracket 52. Use a precision level or laser level to monitor the horizontality of the roller cantilever beam 15 in real time. After the leveling of the roller cantilever beam 15 is completed, tighten the fixing bolt to completely fix the roller cantilever beam 15.

[0040] At the same time, observe the deformation of the roller cantilever beam 15 when the conveyor belt 2 is running at different loads. If necessary, perform further fine-tuning according to the above steps.

[0041] After confirming that all adjustments have reached the optimal state, completely tighten all bolts, record the final adjustment parameters, including the position of the adjustment bolts and nuts 17 and the position of the cantilever beam pull rod 16, etc., and fix the upper insulation cover plate 3 and the lower insulation cover plate 4.

[0042] The lower heat-insulating cover plate 4 is installed above the fixing portion 11 , and the upper heat-insulating cover plate 3 is hingedly arranged on the supporting portion 12 .

[0043] By designing the adjustment mechanism 5 and the cantilever beam pull rod 16, the running parallelism of the conveyor belt can be accurately adjusted, thereby improving the running stability and efficiency of the conveyor belt.

[0044] The design of the H-shaped bracket 52 and the tensioning roller 53 allows the tension of the conveyor belt 2 to be flexibly adjusted to meet different working requirements. The combined use of the adjusting bolts and nuts 17 and the fixing bolts can accurately adjust the horizontality of the outer end of the roller cantilever beam 15, eliminating the downward pressure caused by the tension of the conveyor belt 2 and the downward inclination of the H-shaped bracket 52, ensuring the smooth operation of the conveyor belt 2 and improving the adaptability and reliability of the device.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements and improvements made to the above embodiments based on the technical essence of the present invention should be included in the scope of protection of the technical solution of the present invention.
