For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] refer to Figure 1-4As shown, one embodiment of this utility model is as follows: A belt guide rail includes a rail bracket, with a guide rail at the upper end of the rail bracket. A wear-resistant component is provided inside the guide rail. An mounting cylinder 1 is provided on the rail bracket below the guide rail. The groove opening direction of the guide rail is perpendicular to the axial direction of the mounting cylinder 1. L-shaped adjusting plates 2 are provided on both sides of the mounting cylinder 1 on the rail bracket. The horizontal part of the L-shaped adjusting plate 2 is located behind the rail bracket. The vertical part of the L-shaped adjusting plate 2 is connected to the rail bracket by bolt fasteners. A first strip hole 3 adapted to the bolt fasteners is opened on the vertical part.

[0027] By using the slotted holes on the L-shaped adjusting plate 2 and the bolt fasteners, the heights of the two L-shaped adjusting plates 2 can be made different. During installation, the horizontal part is aligned with the lower edge of the frame to achieve the desired effect. Figure 4 The height difference between the left and right sides, as shown, allows for angle adjustment during belt guide slot installation. The mounting cylinder is then fixed to the existing roller bearing fixing shaft, thus securing the belt guide slot. After the belt guide slot is fixed, the horizontal part abuts against the lower edge of the frame, preventing the belt guide slot from deflecting and ensuring its stable position during use.

[0028] like Figure 4 The demonstrated installation configuration shows the belt guide rail with the left side higher than the right. It is understood that in actual use, the height difference between the L-shaped adjusting plates 2 on both sides can be adjusted as needed to achieve an installation configuration where the left side is lower than the right, or where both sides of the belt guide rail remain horizontal. The specific configuration can be implemented according to actual conditions, and this application does not impose any limitations. By adjusting the height difference between the L-shaped adjusting plates 2 on both sides, the angle of the belt guide rail can be adjusted, thereby ensuring the belt is in optimal tension, effectively preventing the timing belt from running off-center, and demonstrating high practicality.

[0029] Specifically, the bracket includes side fixing plates 4 arranged opposite each other, a front mounting plate 5 and a rear mounting plate 6 are provided between the side fixing plates 4, the mounting cylinder 1 is provided on the front mounting plate 5 and the rear mounting plate 6, a second strip hole 7 adapted to the bolt fastener is provided on the side fixing plate 4 behind the rear mounting plate 6, and the guide groove is provided at the upper end of the side fixing plate 4, the front mounting plate 5 and the rear mounting plate 6.

[0030] Bolt fasteners include fastening bolts 8 and fastening nuts 9.

[0031] The mounting cylinder 1 has a fixing hole, and the fixing hole has a threaded connecting post 10. The threaded connecting post 10 has a threaded fixing hole, and the threaded fixing hole is coaxial with the fixing hole.

[0032] Because the wall thickness of the mounting cylinder 1 is relatively small, directly setting a threaded hole on the mounting cylinder 1 would result in poor stability after installation and fixing. Therefore, this application provides a fixing hole on the mounting cylinder for setting a threaded connecting post 10, thereby increasing the threaded mating surface and improving stability during installation and fixing.

[0033] For the installation and fixing of the mounting cylinder, the existing fixed shaft 17 on the frame for mounting the roller bearing is used to reduce the equipment modification cost. During installation, the mounting cylinder 1 is fitted onto the existing fixed shaft 17, and then the height difference of the L-shaped adjusting plates 2 on both sides is adjusted to a suitable position. The threaded end of the fastening bolt 8 is passed through the lower strip hole 3 and the second strip hole 7, and then the fastening nut 9 is connected and locked. Then, the locking bolt is tightened onto the threaded fixing hole of the threaded connecting column 10 and pressed against the fixed shaft 17 to fix it, thus realizing the installation and fixing of the belt guide groove. The operation is simple and convenient.

[0034] The L-shaped adjusting plate 2 is adjusted by using strip holes and bolt fasteners, which is simple to operate and easy to maintain.

[0035] This application uses a locking bolt to abut against the fixed shaft to achieve the connection and fixation of the mounting cylinder 1. There are three reasons why a threaded connection is not achieved by directly creating a threaded hole on the fixed shaft: first, the fixed shaft 17 is relatively small, making it difficult to drill a hole (threaded hole) on it; second, drilling a hole on the fixed shaft would easily reduce its structural strength, leading to damage during long-term operation; and third, while direct drilling simplifies installation and fixation, it also fixes the installation position, making it impossible to adjust according to the guiding needs of the synchronizing device.

[0036] The front mounting plate 5 and rear mounting plate 6 in this application are fixed to the front and rear ends of the mounting cylinder 1 respectively by two mounting plates, which is a trade-off considering both economy and stability. It is understood that those skilled in the art can increase or decrease the number of mounting plates according to the actual situation in specific implementations.

[0037] In this embodiment, the guide slot includes a support plate 11 and a side plate 12. The side plate 12 is provided on the front and rear sides of the support plate 11. The wear-resistant component includes a first wear-resistant plate 13 and a second wear-resistant plate 14. The first wear-resistant plate 13 is fixedly connected to the support plate 11. The second wear-resistant plate 14 is engaged between the first wear-resistant plate 11 and the side plate 12. The outer edge of the side plate 12 is provided with an anti-detachment plate 15 adapted to the second wear-resistant plate 14.

[0038] Specifically, the first wear-resistant plate 13 is one of silicon carbide plate, alumina ceramic plate, silicon nitride plate, polymer wear-resistant plate, and nano-ceramic plate; the second wear-resistant plate 14 is one of silicon carbide plate, alumina ceramic plate, silicon nitride plate, polymer wear-resistant plate, and nano-ceramic plate. Those skilled in the art can select the wear-resistant plate made of the above materials according to the actual situation.

[0039] In terms of the shape of the wear-resistant plates, both the first wear-resistant plate 13 and the second wear-resistant plate 14 are arc-shaped plates with a high middle and low sides.

[0040] The support plate 11 is provided with limiting strips 16 on the left and right sides, which are adapted to the first wear-resistant plate 13.

[0041] In the installation of the wear-resistant plate, the second wear-resistant plate 14 is first placed in the groove formed by the support plate 11 and the side plate 12, and then the first wear-resistant plate is placed between the two side plates 12 and fixed to the support plate 11 by means of threads. Therefore, the first wear-resistant plate 13 and the support plate 11 are provided with mutually mating mounting holes.

[0042] The first wear-resistant plate and the second wear-resistant plate 14 effectively prevent belt misalignment, effectively extend the service life of the equipment, and reduce costs.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
