Description

Technical Field

[0001] The utility model relates to the technical field of tensioning devices for hanging transmission, in particular to an active tensioning device for hanging brushes. Background Art

[0002] Suspension transmission technology is an engineering technology that uses suspension to transport objects. It has a wide range of applications in multiple industries, including but not limited to manufacturing, logistics, clothing production, building materials transportation and other fields.

[0003] In overhead transmission, an electric motor and a chain are used as the transmission medium, but the movement between the sprockets where the chain enters or leaves is unstable.

[0004] When the sprocket drives the chain to rotate, the chain itself is composed of a series of rigid links. As these links pass around the sprocket, each link acts as a rigid body and exerts different forces on the sprocket at different positions, forming the so-called "polygon effect." This causes the chain's instantaneous speed and acceleration to vary periodically over time, resulting in uneven motion. This effect is particularly noticeable at high speeds.

[0005] The number of sprocket teeth and the chain pitch have a significant impact on the smoothness of the transmission. If the small sprocket has too few teeth, the contact time between each chain link and the sprocket teeth is short, and the impact force during each engagement is large, which will increase the instability of the movement.

[0006] A chain that is too loose or too tight will affect its stability. When the chain is too loose, it is easy to jump or slide on the sprocket, increasing the irregularity of movement; when it is too tight, it will increase the wear of the chain and sprocket, and also affect the stability of the transmission.

[0007] Lack of effective lubrication will increase the friction resistance between the chain and the sprocket, which will not only increase energy consumption, but also make the chain more prone to tooth jumping. Especially under high-speed operation and heavy load conditions, poor lubrication will significantly reduce the smoothness of the transmission.

[0008] As the chain and sprocket are used for a long time, they will be deformed due to wear, the gap between the chain links will increase, and the sprocket teeth will wear out, which will make the chain movement more unstable during the transmission process.

[0009] Therefore, how to provide an active tensioning device for a hanging brush is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0010] One purpose of the present invention is to propose an active tensioning device for a hanging brush. The present invention avoids the rigid body of each link of the chain body from exerting different forces on the straight-hole sprocket at different positions through the cooperation of the PE guide rail, the brush sub-guide rail, the tensioning plate and the chain baffle, thereby forming a so-called "polygonal effect", which causes the instantaneous speed and acceleration of the straight-hole sprocket to change periodically with time, thereby causing the phenomenon of uneven movement, which causes the chain body to separate from the straight-hole sprocket. In severe cases, the chain body is broken. The brush sub-guide rail staggers the chain bodies on both sides of the PE guide rail to avoid chain jamming and ensure stable operation of the chain body.

[0011] According to an embodiment of the utility model, an active tensioning device for a hanging brush includes a track body, a track bracket, a PE guide rail, a tensioning plate, a chain baffle and a brush tensioning base plate, wherein the top of the track bracket is fixedly mounted on the track body, the PE guide rail is fixedly mounted on the bottom of the track bracket, the brush tensioning base plate is fixedly mounted on the end of the PE guide rail away from the track bracket, the tensioning plate is fixedly mounted on the brush tensioning base plate, the chain baffle is fixedly mounted on the brush tensioning base plate, and the chain baffle and the tensioning plate are located on the same side, and the chain baffle is located above the tensioning plate.

[0019] The beneficial effects of the utility model are:

[0020] The utility model prevents the rigid body of each link of the chain body from exerting different forces on the straight-hole sprocket at different positions through the cooperation of the PE guide rail, the brush sub-guide rail, the tensioning plate and the chain baffle, which causes the instantaneous speed and acceleration of the straight-hole sprocket to change periodically with time, thereby causing the phenomenon of uneven movement, which in turn causes the chain body to separate from the straight-hole sprocket. In severe cases, the chain body is caused to break. The brush sub-guide rail staggers the chain bodies on both sides of the PE guide rail to avoid chain jamming and ensure the stable operation of the chain body. BRIEF DESCRIPTION OF THE DRAWINGS

Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0024] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0025] In the hanging transmission, the power motor 3 and the chain body 4 are used as the transmission medium, but the movement between the chain body 4 entering or leaving the straight-hole sprocket 11 is unstable. When the straight-hole sprocket 11 drives the chain body 4 to rotate, since the chain body 4 itself is composed of a series of rigid chain links, when these chain links pass around the straight-hole sprocket 11, each chain link acts as a rigid body and will produce different forces on the straight-hole sprocket 11 at different positions, forming the so-called "polygonal effect", which causes the instantaneous speed and acceleration of the chain body 4 to change periodically with time, thereby causing uneven movement. This effect is more obvious especially when running at high speeds.

[0026] The number of teeth of the straight-hole sprocket 11 and the pitch of the chain body 4 have an important influence on the smoothness of the transmission; if the number of teeth of the small straight-hole sprocket 11 is too small, the contact time of each chain link with the teeth of the straight-hole sprocket 11 is short, and the impact force during each engagement is large, which will aggravate the instability of the movement; if the chain body 4 is too loose or too tight, its smoothness will be affected; when the chain body 4 is too loose, it is easy to jump or slide on the straight-hole sprocket 11, increasing the irregularity of the movement; if it is too tight, the wear of the chain body 4 and the straight-hole sprocket 11 will be increased, which will also affect the stability of the transmission; lack of effective lubrication will lead to an increase in the friction resistance between the chain body 4 and the straight-hole sprocket 11, which will not only increase energy consumption, but also make the chain body 4 more likely to jump teeth. Especially under high-speed operation and heavy load conditions, poor lubrication will significantly reduce the smoothness of the transmission.

[0027] To solve the above problems, the following solutions are proposed:

[0028] Please refer to Figure 1 The utility model provides an active tensioning device for hanging brushes, comprising a track body 1, a track bracket 5, a PE guide rail 6, a tensioning plate 8, a chain baffle 9 and a brush tensioning base plate 10, wherein the top of the track bracket 5 is fixedly mounted on the track body 1, the PE guide rail 6 is fixedly mounted on the bottom of the track bracket 5, the brush tensioning base plate 10 is fixedly mounted on the end of the PE guide rail 6 away from the track bracket 5, the tensioning plate 8 is fixedly mounted on the brush tensioning base plate 10, the chain baffle 9 is fixedly mounted on the brush tensioning base plate 10, and the chain baffle Plate 9 and tensioning plate 8 are located on the same side, and chain baffle 9 is located above tensioning plate 8. Tensioning plate 8 and chain baffle 9 enable the chain to smoothly enter PE guide rail 6 to prevent the chain from running out of PE guide rail 6. Brush tensioning base plate 10 is located below track body 1 and also includes brush auxiliary guide rail 7. Brush auxiliary guide rail 7 is fixedly installed inside PE guide rail 6. Brush auxiliary guide rail 7 is located in the middle of PE guide rail 6. Brush auxiliary guide rail 7 divides PE guide rail 6 into two parts, staggering the relative chains to avoid chain jamming.

[0029] The utility model provides an active tensioning device for hanging brushes, which also includes a motor support plate 2 and a power motor 3. The top of the motor support plate 2 is fixedly mounted on the end of the track body 1 away from the track bracket 5. The motor seat of the power motor 3 is fixedly mounted on the motor support plate 2. The side of the motor support plate 2 facing the PE guide rail 6 is fixedly connected to the side of the motor support plate 2 away from the PE guide rail 6. It also includes a chain body 4 and a straight-hole sprocket 11. The chain body 4 is sleeved on the straight-hole sprocket 11. The power motor 3 drives the straight-hole sprocket 11 to rotate. The chain body 4 driven by the straight-hole sprocket 11 rotates. The straight-hole sprocket 11 is fixedly mounted on the rotating shaft of the power motor 3. The straight-hole sprocket 11 is slidably mounted between the PE guide rail 6 and the brush auxiliary guide rail 7. The straight-hole sprocket 11 is slidably mounted between the tensioning plate 8 and the chain baffle 9. The straight-hole sprocket 11 is slidably mounted between the tensioning plate 8 and the inner top of the brush tensioning bottom plate 10.

[0030] Furthermore, the power motor 3 is started, and the rotating shaft of the power motor 3 drives the straight hole sprocket 11 to rotate, and the rotation of the straight hole sprocket 11 drives the chain body 4 to move.

[0031] The chain body 4 moves out from between the inner bottom of the PE guide rail 6 and the bottom of the brush auxiliary guide rail 7, passes through between the tensioning plate 8 and the chain baffle 9 and enters the straight hole sprocket 11, and the straight hole sprocket 11 turns with the chain body 4, and the chain body 4 passes through the inner top of the brush tensioning bottom plate 10 and between the chain baffle 9, and then enters between the inner top of the PE guide rail 6 and the top of the brush auxiliary guide rail 7.

[0032] The tensioning plate 8 and the chain baffle 9 are used to limit the movement space of the chain body 4 to prevent the rigid body of each link of the chain body 4 from exerting different forces on the straight-hole sprocket 11 at different positions, forming the so-called "polygonal effect", which causes the instantaneous speed and acceleration of the straight-hole sprocket 11 to change periodically with time, thereby causing the phenomenon of uneven movement, causing the chain body 4 to detach from the straight-hole sprocket 11, and in severe cases, causing the chain body 4 to break.

[0033] The brush auxiliary guide rail 7 divides the PE guide rail 6 into two parts, staggering the chain bodies 4 on both sides of the PE guide rail 6 to move smoothly, avoiding chain jamming and ensuring stable operation of the chain body 4.
