Description

Technical Field

[0001] This application relates to the field of friction roller technology, and more particularly to an anti-slip friction roller assembly. Background Technology

[0002] Currently, friction rollers are core components that utilize friction to achieve specific functions, and are widely used in material transport, processing, and handling in industrial production. Their function varies depending on the application scenario; by using the friction between the roller and the material surface, rotational power is converted into linear or curvilinear motion of the material, enabling continuous conveying. In practical applications, the structure of the friction roller (such as material, surface texture, and drive method) needs to be customized according to the working conditions to maximize its frictional advantages while avoiding slippage or wear.

[0003] However, existing friction roller assemblies have the following drawbacks: for example, when materials are placed on the surface of the friction roller for transmission, in order to prevent excessive friction from causing wear on the surface of the materials, friction rollers with moderate friction are generally used. However, after a period of use, the surface of the friction roller will wear down, resulting in a decrease in friction and slippage, which reduces the practicality of the device. Summary of the Invention

[0004] The purpose of this application is to adjust the friction force of the friction roller when slippage occurs, thereby achieving an anti-slip function.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A base is included, comprising a base plate. A first rotating mechanism is mounted on the upper surface of the base plate. The first rotating mechanism includes a first support block, the bottom of which is fixedly connected to the upper surface of the base plate. A first rotating shaft is movably connected inside the first support block. A friction mechanism is mounted on the surface of the first rotating shaft. The friction mechanism includes a first rotating roller, which is fixedly connected to the surface of the first rotating shaft. A second rotating roller is fixedly connected to the surface of the first rotating roller. A cylinder is fixedly connected to the surface of the first rotating roller. A pressure plate is fixedly connected to the telescopic end of the cylinder. A top plate is fixedly connected to the upper surface of the base plate. A second rotating mechanism is mounted on the lower surface of the top plate. The second rotating mechanism includes a second support block, the upper surface of which is fixedly connected to the lower surface of the top plate. A gear is provided on the outer wall of the second support block. A detection mechanism is mounted on the right side surface of the second support block. The detection mechanism includes a support plate, the left side of which is fixedly connected to the right side surface of the second support block. A tachometer is fixedly connected to the upper surface of the support plate.

[0006] As a preferred embodiment, the surface of the second rotating roller is provided with a through hole, the inner wall of the through hole is in contact with the surface of the pressure plate, and the cylinder is located inside the second rotating roller.

[0007] As a preferred embodiment, a third rotating shaft is movably connected inside the second support block, the surface of the third rotating shaft is fixedly connected to the inner wall of the gear, and a third rotating roller is fixedly connected to the surface of the third rotating shaft.

[0008] As a preferred embodiment, a power mechanism is mounted on the surface of the base. The power mechanism includes a motor, the main body of which is fixedly connected to the surface of the base, and the output end of the motor is fixedly connected to a second rotating shaft. A second synchronous pulley is fixedly connected to the surface of the second rotating shaft.

[0009] As a preferred embodiment, a first synchronous pulley is fixedly connected to the surface of the first rotating shaft. The first synchronous pulley is located to the right of the first rotating roller, and a synchronous belt is installed on the surface of the first and second synchronous pulleys.

[0010] As a preferred embodiment, an auxiliary mechanism is installed on the surface of the base. The auxiliary mechanism includes a push block, the surface of which is fixedly connected to the surface of the base. An electric telescopic rod is fixedly connected to the surface of the push block, and an inclined block is fixedly connected to the telescopic end of the electric telescopic rod.

[0011] Compared with the prior art, the beneficial effects of this application are as follows:

[0012] (1) In use, when the device is started, it will drive the long strip of material placed on the upper surface of the second rotating roller to move, and the third rotating roller will also come into contact with the surface of the long strip of material, causing the third rotating roller to rotate. The gear will also rotate. The tachometer installed on the right side of the gear can be used to measure the rotation speed of the gear. When the long strip of material is still being transported above the device, the rotation speed of the gear is close to 0, which means that slippage has occurred. At this time, the cylinder fixed on the first rotating roller is started, so that the cylinder extends and drives the pressure plate to extend out of the through hole and come into contact with the surface of the material, increasing the contact area and preventing slippage. Compared with conventional devices, when the material is placed on the surface of the friction roller for transmission, in order to prevent excessive friction and wear on the surface of the material, a friction roller with moderate friction is generally used. After a period of use, the surface of the friction roller will wear down, resulting in a decrease in friction and slippage, which reduces the practicality of the device. This device can adjust the friction of the friction roller when slippage occurs, thereby achieving the anti-slip function and improving the practicality of the device.

[0013] (2) When it is necessary to replace the first synchronous pulley installed in the synchronous belt during use, the electric telescopic rod on the push block can be activated to extend the electric telescopic rod and drive the two inclined blocks to move to the upper left and lower left, lifting the synchronous belt so that the synchronous belt no longer contacts the surface of the first synchronous pulley. At this time, the first synchronous pulley can be easily disassembled, which improves the practicality of the device. Attached Figure Description

A pressure plate 403 is fixedly connected to the telescopic end of the cylinder 402. A top plate 102 is fixedly connected to the upper surface of the base 101. A second rotating mechanism 5 is mounted on the lower surface of the top plate 102, which includes a second support block 501, the upper surface of which is fixedly connected to the lower surface of the top plate 102. Gears 504 are provided on the outer wall of the second support block 501. A detection mechanism 6 is installed on the right side surface of the second support block 501. The detection mechanism 6 includes a support plate 601. The left side surface of the support plate 601 is fixedly connected to the right side surface of the second support block 501. A tachometer 602 is fixedly connected to the upper surface of the support plate 601. When the device is started, it will drive the long strip of material placed on the upper surface of the second rotating roller 404 to move. The third rotating roller 503 will also come into contact with the surface of the long strip of material, causing the third rotating roller 503 to rotate. The gear 504 will also rotate accordingly. The tachometer 602 installed on the right side of the gear 504 can be used to measure the rotation speed of the gear 504. When the long strip of material is still being transported above the device, the rotation speed of the gear 504 is close to 0, which means that slippage has occurred. At this time, the cylinder 402 fixed on the first rotating roller 401 is activated, causing the cylinder 402 to extend and drive the pressure plate 403 to extend out of the through hole 405 and come into contact with the surface of the material, increasing the contact area and preventing slippage.

[0025] The surface of the second rotating roller 404 has a through hole 405, the inner wall of the through hole 405 is in contact with the surface of the pressure plate 403, the cylinder 402 is located inside the second rotating roller 404, the inside of the second support block 501 is movably connected to the third rotating shaft 502, the surface of the third rotating shaft 502 is fixedly connected to the inner wall of the gear 504, the surface of the third rotating shaft 502 is fixedly connected to the third rotating roller 503, the surface of the base 101 is mounted with a power mechanism 3, the power mechanism 3 includes a motor 302, the main body end of the motor 302 is fixedly connected to the surface of the base 101, the output end of the motor 302 is fixedly connected to the second rotating shaft 303, the surface of the second rotating shaft 303 is fixedly connected to the second synchronous pulley 304, the surface of the first rotating shaft 202 is fixedly connected to the first synchronous pulley 203, the first synchronous pulley 203 is located on the right side of the first rotating roller 401, the first... A timing belt 301 is mounted on the surface of a timing pulley 203 and a timing pulley 304. An auxiliary mechanism 7 is mounted on the surface of the base 101.

An electric telescopic rod 702 is fixedly connected to the surface of the push block 703. An inclined block 701 is fixedly connected to the telescopic end of the electric telescopic rod 702. When it is necessary to replace the first timing pulley 203 installed in the timing belt 301, the electric telescopic rod 702 on the push block 703 can be activated to extend the electric telescopic rod 702, which drives the two inclined blocks 701 to move to the upper left and lower left, lifting the timing belt 301 so that the timing belt 301 is no longer in contact with the surface of the first timing pulley 203. At this time, the first timing pulley 203 can be easily disassembled, improving the practicality of the device.

[0026] Working principle: When the device starts, it moves the long strip of material placed on the upper surface of the second rotating roller 404, and the third rotating roller 503 also comes into contact with the surface of the long strip of material, causing the third rotating roller 503 to rotate. The gear 504 also rotates accordingly. The tachometer 602 installed on the right side of the gear 504 can be used to measure the rotation speed of the gear 504. When the long strip of material is still being transported above the device, the rotation speed of the gear 504 is close to 0, which means that slippage has occurred. At this time, the cylinder 402 fixed on the first rotating roller 401 is activated, causing the cylinder 402 to extend. The length of the pusher block 703 causes the pressure plate 403 to extend out of the through hole 405 and contact the surface of the material, increasing the contact area and preventing slippage. When it is necessary to replace the first synchronous pulley 203 installed in the synchronous belt 301, the electric telescopic rod 702 on the pusher block 703 can be activated to extend the electric telescopic rod 702, causing the two inclined blocks 701 to move to the upper left and lower left, lifting the synchronous belt 301 so that the synchronous belt 301 is no longer in contact with the surface of the first synchronous pulley 203. At this time, the first synchronous pulley 203 can be easily disassembled, improving the practicality of the device.
