Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically to a roller clamping device. Background Technology

[0002] In the use of roller equipment, the rollers are mostly driven by structures such as belts, chains, and reducers. Since the rollers are often used in environments with high extrusion pressure, a drive structure with high torque is required. However, during use, rollers inevitably experience overload during extrusion and conveying. In such cases, belt slippage and motor overload and burnout often occur. Especially in processes where operators are required to assist with feeding, their hands are often squeezed into the rollers in case of an accident due to their proximity. Installing a grating would greatly limit production efficiency. Therefore, this technical solution is proposed to improve the situation. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies in which there are no protective measures when rollers are overloaded during use, and to provide a roller clamping device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a roller clamping device, comprising a toothed pressure roller mounted on a frame, a sliding device at the end of the toothed pressure roller, the sliding device comprising a driving part mounted on the upper part, a worm gear at the output end of the driving part connected to the toothed pressure roller, and an adjustment device for pushing the worm gear on the side of the driving part.

[0005] Furthermore, the end of the toothed pressure roller is provided with a worm gear and connected to a worm, and the driving part is a drive motor, which is located on the upper part of the worm.

[0006] Furthermore, an operating box is provided at the lower part of the drive motor, the worm gear is located inside the operating box, and a slider is provided at the bottom of the operating box, the slider being slidably connected to a guide rail provided on the frame.

[0007] Furthermore, the adjustment device is disposed on the side of the control box opposite to the toothed pressure roller. The adjustment device includes a compression spring disposed on the side of the control box, and a pressure cap is disposed on the other end of the compression spring. An adjustment rod for adjusting pressure is disposed on the side of the pressure cap, and the adjustment rod is screwed to the frame.

[0008] Furthermore, at least two compression springs are provided, and a pressure sensor is provided at the bottom of the pressure cap.

[0009] The beneficial effects of this utility model embodiment are as follows: When it is necessary to adjust the clamping pressure of the toothed pressure roller on the material, simply rotate the adjusting rod. Since the adjusting rod is screwed to the frame, rotating the adjusting rod will cause it to move in the axial direction, thereby pushing or pulling the pressure cover and changing the compression amount of the pressure spring. The change in the compression amount of the pressure spring will directly affect the pressure on the toothed pressure roller, thereby realizing the adjustment of the clamping pressure. It can adjust the clamping pressure and does not require the installation of safety devices such as optical gratings that limit production efficiency. While ensuring the safety of operators, it also improves production efficiency. Attached Figure Description

[0013] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0014] See Figures 1 to 2 This utility model discloses a roller clamping device. In practical applications of roller equipment, such as in metal sheet processing, ore conveying, and food packaging, the driving method for rollers typically employs structures such as belts, chains, and reducers. However, since the working environment of rollers often involves significant compressive force, the driving structure must possess a large torque to ensure normal roller operation. This is especially true in scenarios requiring operator assistance with material feeding, such as on metal parts processing production lines, where operators need to place parts onto the rollers at close range for conveying and processing.

[0015] This technical solution mainly consists of a toothed pressure roller 2 mounted on the equipment frame 1. A sliding device is installed at the end of the toothed pressure roller 2, and a drive unit is located above the sliding device. This drive unit uses a drive motor, which is positioned above a worm gear 301. The output end of the drive motor is connected to the worm gear 301, which in turn is connected to the toothed pressure roller 2. This design allows the drive motor to stably transmit power to the toothed pressure roller 2 through the worm gear 301, thereby realizing the rotation of the toothed pressure roller 2. Simultaneously, a worm wheel 302 is also installed at the end of the toothed pressure roller 2. The worm wheel 302 cooperates with the worm gear 301 to form a worm wheel 302-worm gear 301 transmission mechanism, improving the stability and reliability of the device during use and ensuring its effectiveness.

[0016] To facilitate the overall operation and protection of the drive unit and worm gear 301, an operation box 3 is provided at the bottom of the drive motor. The worm gear 301 is placed inside the operation box 3. The right side of the operation box 3 is open to facilitate the connection between the worm gear 301 and the worm wheel 302. A slider is installed at the bottom of the operation box 3. The slider is slidably connected to the guide rail 303 set on the frame 1. With this design, the operation box 3 can slide along the guide rail 303, thereby driving the entire sliding device to adjust its position in the horizontal direction to adapt to different clamping requirements.

[0017] An adjustment device is installed on the side of the control box 3, opposite to the toothed pressure roller 2. The adjustment device includes a compression spring 401 installed on the side of the control box 3, with the other end of the compression spring 401 connected to a pressure cover. An adjustment rod 4 for adjusting pressure is installed on the side of the pressure cover. The adjustment rod 4 is screwed to the frame 1. When it is necessary to adjust the clamping pressure of the toothed pressure roller 2 on the material, simply rotate the adjustment rod 4. Since the adjustment rod 4 is screwed to the frame 1, rotating the adjustment rod 4 will cause it to move axially, thereby pushing or pulling the pressure cover and changing the compression of the compression spring 401. The change in the compression of the compression spring 401 will directly affect the pressure on the toothed pressure roller 2, thus achieving the adjustment of the clamping pressure. When the resistance of the roller is too high during clamping and conveying, the resistance between the worm gear 301 and the worm wheel 302 can be adjusted. Slippage occurs between the worm gear 301 and the worm wheel 302. During this process, the entire control box 3 will move to the left to prevent the drive motor from overloading and burning out, ensuring the effectiveness of use and improving safety.

[0018] To ensure the stability and uniformity of pressure regulation, at least two pressure springs 401 are provided. This avoids pressure fluctuations caused by uneven force on a single pressure spring 401. Simultaneously, a pressure sensor is installed at the bottom of the pressure cap. The pressure sensor monitors the pressure on the pressure cap in real time and converts the pressure signal into an electrical signal, which is then transmitted to the control system. Based on the received pressure signal, the control system ensures that the toothed pressure roller 2 always clamps the material with appropriate pressure, preventing slippage due to insufficient pressure and damage to the material or equipment due to excessive pressure. In case of overload, the system promptly cuts off power to ensure safe operation.

[0019] In actual use, when the material is conveyed to the roller clamping device, the drive motor starts, driving the toothed pressure roller 2 to rotate via the worm gear 301 and worm wheel 302. During material conveying, if overload occurs, the device prevents motor burnout due to the use of a pressure sensor. When operators assist with feeding, the device can adjust the clamping pressure and does not require safety devices such as optical gratings that limit production efficiency, thus ensuring operator safety while improving production efficiency.
