[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a servo motor transfer mechanism with a synchronous belt tension adjustment wheel, including a base 1. A motor body 2 is fixedly connected inside the base 1. A drive wheel 3 is fixedly installed at the output end of the motor body 2. A synchronous belt body 4 is meshed with the tooth end of the drive wheel 3. A tension wheel 5 is meshed with the tooth end of the synchronous belt body 4. A support frame 6 is rotatably connected inside the tension wheel 5. A fixed box 7 is slidably connected to the outer wall of the support frame 6. The outer wall of the fixed box 7 is located inside the base 1. A lead screw 8 is rotatably connected inside the fixed box 7. A disc 9 is fixedly connected to the top end of the lead screw 8. A limit rod 10 is slidably connected inside the disc 9. A wedge block 11 is threadedly connected to the outer wall of the lead screw 8. A T-shaped block 12 is fixedly connected to the outer wall of the wedge block 11. The outer walls of both the wedge block 11 and the T-shaped block 12 are slidably connected inside the support frame 6. An auxiliary component is provided on the outer wall of the limit rod 10.

[0026] Specifically, the synchronous belt body 4 is connected to the conveyor belt or other conveying mechanism to realize the movement of materials. The positions of the motor body 2 and drive wheel 3 remain unchanged, and the position of the fixed box 7 also remains unchanged. By moving the support frame 6 and tension wheel 5 left and right, the right end of the synchronous belt body 4 is compressed or released, thereby adjusting the overall tension of the synchronous belt body 4. The fixed box 7 has multiple grooves inside, which facilitates the small-distance rotation of the lead screw 8 and the disc 9 as needed. With the cooperation of the limit rod 10 and auxiliary components, the rotation of the disc 9 and the lead screw 8 is limited to prevent the lead screw 8 from rotating unexpectedly, thereby enhancing the stability of the inclined block 11 and the support frame 6. The outer wall of the inclined block 11 is provided with a guide rail and a T-shaped block 12. The guide rail assists the sliding of the support frame 6, while the outer wall of the T-shaped block 12 slides inside the support frame 6, limiting the sliding of the support frame 6 and preventing the support frame 6 from accidentally leaving the range of the inclined block 11.

[0027] Reference Figure 3 The auxiliary component includes a circular block 13, the inside of which is fixedly connected to the outer wall of the limiting rod 10. A spring 14 is fixedly connected to the upper surface of the circular block 13, and the outer wall of the spring 14 is fixedly connected to the lower surface of the disc 9. The lower surface of the circular block 13 is set on the upper surface of the fixed box 7.

[0028] Specifically, the two ends of spring 14 are connected to the disc 9 and the block 13 respectively. The elastic force of spring 14 causes the block 13 to move downward and fit against the upper surface of the fixed box 7, thereby pushing the limiting rod 10 into the interior of the fixed box 7 to limit the rotation of the disc 9. Spring 14 provides downward pressure to the limiting rod 10 to assist in limiting the disc 9.

[0029] Reference Figure 2 The bottom end of the limiting rod 10 is slidably connected to the inside of the fixed box 7, and the outer wall of the inclined block 11 is set inside the fixed box 7;

[0030] Specifically, a slide rail is provided inside the fixed box 7, and the inside of the inclined block 11 moves on the outer wall of the slide rail, thereby restricting the movement of the inclined block 11.

[0031] Reference Figure 4 and Figure 5 Both the base 1 and the fixing box 7 are equipped with screw brackets 15 inside. The outer wall of the screw bracket 15 is threaded with a cross 16. The lower surface of the cross 16 is equipped with a protective pad 17, and the lower surface of the protective pad 17 is set on the lower surface of the fixing box 7. The screw bracket 15 is rotatably connected with a fixing rod 18, and the outer wall of the fixing rod 18 is fixedly connected with a limit block 19. The limit block 19 is fixedly connected with a second spring 20, and the outer wall of the second spring 20 is fixedly connected to the inside of the screw bracket 15. The outer wall of the limit block 19 is set inside the screw bracket 15, and the upper surface of the limit block 19 is set on the lower surface of the base 1.

[0032] Specifically, grooves are provided inside both the base 1 and the fixing box 7 for the movement of the screw bracket 15 between the base 1 and the fixing box 7. The protective pad 17 is made elastic, and the cross 16 is tightened between the screw bracket 15, so that the upper surface of the limiting block 19 abuts against the lower surface of the base 1, and the lower surface of the protective pad 17 is in close contact with the upper surface of the fixing box 7, forming opposing forces, thereby improving the stability of the fixing box 7 installed on the base 1. The rotation of the fixing rod 18 and the limiting block 19 is limited by the inside of the screw bracket 15. The two ends of the spring 20 are connected to the screw bracket 15 and the limiting block 19, thereby limiting the range of rotation of the limiting block 19.

[0033] Working principle: When using the adjusting wheel, the motor body 2 drives the drive wheel 3. Through the cooperation between the toothed end inside the synchronous belt body 4 and the drive wheel 3 and tension wheel 5, the drive wheel 3, synchronous belt body 4 and tension wheel 5 rotate in the same direction. The synchronous belt body 4 acts as a conveyor belt or connects with other conveying structures to realize the movement of materials. By pulling the limit rod 10, the round block 13 moves upward and squeezes the spring 14. After the bottom end of the limit rod 10 slides out of the fixed box 7, the disc 9 and the lead screw 8 are rotated. Through the cooperation between the inclined block 11 and the lead screw 8, the inclined block 11 is driven to move up and down inside the fixed box 7. Through the inclined surface of the inclined block 11 and the T-shaped block 12, the support frame 6 is pushed to move left and right inside the fixed box 7, thereby driving the tension wheel 5 to move left and right inside the synchronous belt body 4, thereby adjusting the tension of the synchronous belt body 4. Finally, the limit rod 10 is released. Under the elastic force of the spring 14, the limit rod 10 slides into the fixed box 7 for limiting.

[0034] By rotating the cross 16, the cross 16 moves upward under the action of the screw bracket 15. After the cross 16 moves, it no longer squeezes the protective pad 17. After the cross 16 moves out of the range of the screw bracket 15, the screw bracket 15 is moved downward and slides out of the interior of the base 1 and the fixing box 7, so that the limiting block 19 no longer contacts the base 1, thereby releasing the fixing box 7. During use, the adjusting wheel not only adjusts the tension of the synchronous belt body 4, but also realizes the overall disassembly of the fixing box 7, so as to clean and maintain the fixing box 7.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
