Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and more specifically, to a multi-buffered mechanism utilizing the pulley principle. Background Technology

[0002] Material conveying is used in various industries. Continuous belt conveying is a common example of material conveying. When conveying belts continuously, multiple sets of guide wheels are usually used for guidance to adapt to different discharge directions. Since the structural strength of belts varies, attention should be paid to the physical properties of the belts during conveying, and appropriate conveying structures should be selected accordingly.

[0003] During the conveying of strip materials, it is common for the material to break due to excessive pulling force when the material is pulled at the discharge end. Traditional buffering methods have limited effectiveness and cannot effectively reduce the pulling and impact force, making it difficult to meet the requirements for continuous and stable material supply, thus affecting production efficiency and product quality. Therefore, it is urgent to design a new type of buffering mechanism to solve the above problems.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a multi-buffered mechanism utilizing the pulley principle, which has the advantages of stability and reliability, thereby solving the problems mentioned in the background technology.

[0006] To achieve the aforementioned advantages of stability and reliability, the specific technical solution adopted by this utility model is as follows: A multi-buffer mechanism utilizing the pulley principle includes a frame, an inlet end, and an outlet end. The inlet end and outlet end are arranged inside the frame. A first guide wheel and a second guide wheel are installed on the inner side of the inlet end, and a third guide wheel is installed on the inner side of the outlet end. A static buffer wheel is installed between the second guide wheel and the third guide wheel inside the frame. A sliding groove is formed on the inner wall of the frame, and a guide rod is fixedly installed inside the sliding groove. A movable seat is slidably sleeved on the outer side of the guide rod. A movable buffer wheel is rotatably connected to the surface of the movable seat, and a spring is sleeved between the movable seat and the inner wall of one end of the sliding groove outside the guide rod.

[0007] Furthermore, both ends of the spring are fixedly connected to the inner wall of the movable seat and one end of the slide groove, respectively.

[0008] Furthermore, the first guide wheel, the second guide wheel, and the third guide wheel are all rotatably connected to the frame via axles, and the static buffer wheel is rotatably connected to the frame via an axle.

[0009] Furthermore, the movable buffer wheel is rotatably connected to the movable seat via an axle, and two sets of movable buffer wheels are arranged.

[0010] Furthermore, the first guide wheel, the second guide wheel, and the third guide wheel have the same structure, and the length of the first guide wheel is greater than the width of the material.

[0011] Furthermore, the first guide wheel, the static buffer wheel, and the dynamic buffer wheel are of the same size.

[0012] Compared with the prior art, this utility model provides a multi-buffered mechanism utilizing the pulley principle, which has the following beneficial effects: (1) This utility model adopts a dynamic buffer wheel, a guide rod, a static buffer wheel, a spring and a movable seat. The static buffer wheel and the dynamic buffer wheel form a double pulley mechanism. When the material is discharged, when the tension of the material is too large and it is pulled, the dynamic buffer wheel is moved towards the static buffer wheel, the spring is compressed, and the movable seat moves along the guide rod to release the excessive tension and thus buffer. The multi-buffer mechanism of this utility model uses the principle of pulley lever and adopts a double pulley mechanism, including a static buffer wheel and a dynamic buffer wheel. When the material is pulled at the discharge end, the double pulley mechanism can buffer the pulling force. At the same time, the mechanism is also equipped with a spring track to further buffer the pulling force by using the energy stored in the spring. When the material is pulled at the discharge end, the double pulley mechanism first buffers the pulling force. As the material is pulled, the spring in the spring track is stretched or compressed, and the energy stored in the spring is used to further buffer the pulling force, so that the force of the pulling impact on the material is always kept at a low level, and the continuous and stable transmission of the material is achieved.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0017] According to an embodiment of the present invention, a multi-buffered mechanism utilizing the pulley principle is provided.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3 As shown, a multi-buffer mechanism utilizing the pulley principle according to an embodiment of this utility model includes a frame 1, an inlet end 3, and an outlet end 7. The inlet end 3 and the outlet end 7 are provided inside the frame 1. A first guide wheel 2 and a second guide wheel 4 are installed inside the inlet end 3. The installation height of the second guide wheel 4 is less than that of the first guide wheel 2. A third guide wheel 6 is installed inside the outlet end 7, located below the second guide wheel 4. A static buffer wheel 5 is installed between the second guide wheel 4 and the third guide wheel 6 inside the frame 1. A groove 8 is provided on the inner wall of the frame 1, and a guide rod 9 is fixedly installed inside the groove 8. A movable seat 12 is slidably sleeved on the outer side of the guide rod 9. A movable buffer wheel 11 is rotatably connected to the surface of the movable seat 12. A spring 10 is sleeved between the movable seat 12 and the inner wall of one end of the groove 8 outside the guide rod 9. The static buffer wheel 5 and the movable buffer wheel 11 form a double pulley mechanism for feeding materials. When the material tension is too high and pulling occurs, the moving buffer wheel 11 moves towards the stationary buffer wheel 5 under force, the spring 10 is compressed, and the moving seat 12 moves along the guide rod 9 to release the excessive tension and thus buffer. The multi-buffering mechanism of this utility model uses the pulley lever principle and adopts a double pulley mechanism, including a stationary buffer wheel 5 and a moving buffer wheel 11. When the material is pulled at the discharge end 7, the double pulley mechanism can buffer the pulling force. At the same time, the mechanism is also equipped with a spring 10 track, which uses the energy stored in the spring 10 to further buffer the pulling force. When the material is pulled at the discharge end 7, the double pulley mechanism first buffers the pulling force. As the material is pulled, the spring 10 in the spring 10 track is stretched or compressed, and the energy stored in the spring 10 is used to further buffer the pulling force, so that the force of the pulling impact on the material is always kept at a low level, realizing the continuous and stable transmission of the material.

[0019] In one embodiment, the two ends of the spring 10 are fixedly connected to the inner wall of the movable seat 12 and the slide groove 8, respectively, to improve the stability of the connection.

[0020] In one embodiment, the first guide wheel 2, the second guide wheel 4, and the third guide wheel 6 are all rotatably connected to the frame 1 via axles, and the static buffer wheel 5 is rotatably connected to the frame 1 via axles, which is a common rotatable connection method.

[0021] In one embodiment, the movable buffer wheel 11 is rotatably connected to the movable seat 12 via a wheel axle, and two sets of movable buffer wheels 11 are arranged, which is a common rotatable connection form.

[0022] In one embodiment, the first guide wheel 2, the second guide wheel 4, and the third guide wheel 6 have the same structure, and the length of the first guide wheel 2 is greater than the width of the material, thereby improving the stability of the conveying.

[0023] In one embodiment, the first guide wheel 2, the static buffer wheel 5, and the dynamic buffer wheel 11 are of the same size, which improves the stability of the conveying.

[0024] Working principle: The static buffer wheel 5 and the dynamic buffer wheel 11 form a double pulley mechanism. When the material tension is too high during discharge, the dynamic buffer wheel 11 moves towards the static buffer wheel 5, the spring 10 is compressed, and the moving seat 12 moves along the guide rod 9 to release the excessive tension and thus buffer the material. This multi-buffering mechanism of the present invention uses the pulley lever principle and adopts a double pulley mechanism, including the static buffer wheel 5 and the dynamic buffer wheel 11. When the material is pulled at the discharge end 7, the double pulley mechanism can buffer the pulling force. At the same time, the mechanism is also equipped with a spring 10 track, which uses the stored energy of the spring 10 to further buffer the pulling force. When the material is pulled at the discharge end 7, the double pulley mechanism first buffers the pulling force. As the material is pulled, the spring 10 in the spring 10 track is stretched or compressed, and the stored energy of the spring 10 is used to further buffer the pulling force, so that the pulling impact force on the material is always kept at a low level, and the continuous and stable transmission of the material is achieved.
