Description

Technical Field

[0001] This utility model relates to the field of conveyor belt production technology, specifically to a burr removal device for conveyor belt production. Background Technology

[0002] As a material handling equipment widely used in industrial production, conveyor belts are used to efficiently and stably transport materials from one location to another. They play an indispensable role in many industries such as mining, ports, logistics, food processing, and chemicals. They can greatly improve production efficiency, reduce the labor intensity of manual handling, and enable continuous material transport, ensuring smooth production.

[0003] In some special application scenarios, traditional conveyor belt materials and performance can no longer meet the requirements. For example, in some environments that require radiation resistance, such as the nuclear industry and medical radiology departments, ordinary conveyor belts may age faster due to radiation, leading to a decline in the performance of the conveyor belt or even damage, affecting production safety and efficiency. At the same time, with the increasing awareness of environmental protection, higher requirements have been placed on the environmental performance of conveyor belts. Against this background, high-density radiation-resistant and environmentally friendly PVC lightweight conveyor belts have emerged. These conveyor belts use high-density PVC materials, which can effectively resist the erosion of radiation and extend the service life of the conveyor belt. In high-radiation environments, the molecular structure of this conveyor belt remains stable and will not degrade or become brittle due to radiation. During production, environmentally friendly manufacturing processes and raw materials are used to reduce pollution. Furthermore, during use, this conveyor belt does not release harmful substances, meeting environmental protection requirements. It also reduces the weight of the conveyor belt and lowers the energy consumption of the conveying system. This significantly improves energy efficiency for conveying systems that require frequent start-ups and stops. Moreover, this conveyor belt has high strength and wear resistance, enabling it to adapt to various complex working conditions. Additionally, it possesses good flexibility, allowing it to adapt to different conveying paths.

[0004] Currently, conveyor belts often develop burrs after vulcanization. Vulcanized rubber typically requires edge trimming on both sides. However, current burr removal devices used in conveyor belt production are not suitable for removing burrs from conveyor belts of different widths. They cannot quickly and easily adjust the burr removal position. Furthermore, current burr removal devices are prone to shifting during conveyor belt movement. When the conveyor belt shifts, the relative position between its edge and the burr removal tool constantly changes, resulting in excessive burr removal on one side and insufficient removal on the other, thus reducing the quality of burr removal.

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.

[0020] Please see Figure 1-6 As shown, a burr removal device for conveyor belt production includes a base plate 1. Support frames 2 are provided on the left and right sides of the top of the base plate 1. Two conveying rollers 3 are installed on the upper surface of each support frame 2. An installation box 4 is embedded in the middle of the surface of the base plate 1. An adjustment structure 5 is movably connected inside the installation box 4. Connecting plates 6 are provided through the front and rear sides above the adjustment structure 5. A processing frame 7 is fixed on the top of the connecting plate 6. The processing frame 7 is U-shaped. A drive motor 8 is fixed on the opposite side of the processing frame 7. The output shaft of the drive motor 8 passes through the interior of the processing frame 7 and is fixed with a grinding disc 9. A fixing plate 10 is bolted to the left side of the connecting plate 6. A pushing structure 11 is fixed on the left side of the fixing plate 10. A support rod 12 is fixed on the opposite side of the pushing structure 11. A correction frame 13 is fixed on the top of the support rod 12. The correction frame 13 is U-shaped. A cleaning structure 14 is fixed on the right side above the base plate 1.

[0021] The adjustment structure 5 includes a motor 51, a threaded rod 52, a moving block 53, and a fixing groove 54. The motor 51 is fixed to the front side of the mounting box 4. The threaded rod 52 is rotatably connected inside the mounting box 4, and the output shaft of the motor 51 is fixedly connected to the front end of the threaded rod 52. The moving block 53 is threadedly connected to the front and rear sides of the surface of the threaded rod 52, and the thread directions of the front and rear sides of the surface of the threaded rod 52 are opposite. The fixing groove 54 is opened on the front and rear sides of the top of the mounting box 4, and the lower part of the connecting plate 6 passes through the fixing groove 54 and is fixedly connected to the top of the moving block 53. Limiting grooves 15 are opened on the front and rear sides of the bottom of the inner wall of the mounting box 4. A limiting block 16 is fixed to the bottom of the moving block 53, and the lower part of the limiting block 16 extends into the interior of the limiting groove 15 and slides in connection with the inner wall of the limiting groove 15. When adjusting for different widths... When the conveyor belt is deburred, the operator can turn on the motor 51, which will cause the output shaft of the motor 51 to drive the threaded rod 52 to rotate. The moving block 53 on the surface of the threaded rod 52 will move. Since the thread direction on the front and back sides of the threaded rod 52 is different, the moving blocks 53 on the front and back sides will move in opposite directions. The lower limit block 16 slides inside the limit groove 15. Through the setting of the limit groove 15 and the limit block 16, the moving block 53 can be limited, so that the moving block 53 can only move in the front and back direction, which will drive the processing frame 7 above the connecting plate 6 to move. According to the width of the conveyor belt, the spacing between the grinding discs 9 is adjusted so that the grinding discs 9 contact the edge of the conveyor belt and perform grinding and deburring treatment on the edge of the conveyor belt.

[0022] Both the front and rear sides of the inner wall of the fixing groove 54 are fixed with bellows covers 17, and one side of the bellows cover 17 is fixedly connected to the front and rear surfaces of the connecting plate 6. When the moving block 53 drives the connecting plate 6 above to move in the front and back direction, the bellows cover 17 will shrink or expand with the front and back movement of the connecting plate 6. The bellows cover 17 can seal the fixing groove 54 to prevent the removed burrs and debris from falling into the interior of the mounting box 4 and affecting the threaded rod 52.

[0023] The pushing structure 11 includes a fixed frame 111, a movable frame 112, and a mini cylinder 113. The fixed frame 111 is fixed to the surface of the fixed plate 10 away from the connecting plate 6. The movable frame 112 is located on the left side of the fixed frame 111 and is engaged with the fixed frame 111. The mini cylinder 113 is hinged above and below the surface of the movable frame 112 on the opposite side. The mini cylinder 113 is tilted, and one end of the output shaft of the mini cylinder 113 is hinged to the surface of the fixed frame 111 on the opposite side. When the operator observes that the conveyor belt conveyed by the conveyor roller 3 is deviating, the operator opens the mini cylinder 113 on the front or the mini cylinder 113 on the rear according to the direction of the conveyor belt deviation. This causes the output shaft of the mini cylinder 113 to be pushed out, which in turn causes the movable frame 112 to move the support rod 12. The correction frame 13 on one side pushes the conveyor belt, causing the conveyor belt to change and correct its deviation.

[0024] Two springs 18 are fixed on the upper and lower left and right sides of the inner wall of the processing frame 7. A positioning plate 19 is fixed to the end of the spring 18 away from the inner wall of the processing frame 7. The positioning plate 19 is folded in shape. When the grinding disc 9 deburrs the edge of the conveyor belt, the spring 18 will push the positioning plate 19 out, so that the positioning plate 19 located at the upper and lower positions of the conveyor belt can position the surface of the conveyor belt, increase the stability of the grinding disc 9 when deburring the conveyor belt, and prevent the conveyor belt from moving during deburring.

[0025] The cleaning structure 14 includes a mounting frame 141, a mounting plate 142, and a cleaning brush 143. The mounting frame 141 is fixed to the top surface of the base plate 1 and located on the right side of the processing frame 7. The mounting plate 142 is fixed to the upper and lower sides of the surface of the mounting frame 141. The cleaning brush 143 is fixed to the surface of the mounting plate 142 on the opposite side. After the grinding discs 9 on both sides have finished deburring the edges of the conveyor belt, the moving conveyor belt will pass through the cleaning brush 143. The cleaning brushes 143 on the upper and lower sides will clean the upper and lower surfaces of the conveyor belt, removing the debris attached to the surface of the conveyor belt, so that the conveyor belt can be processed later.

[0026] Electric push rods 20 are installed on the front and back sides of the top left and right sides of the base plate 1. Sliding plates 21 are fixed on the lower surface of the support frame 2. One end of the output shaft of the electric push rod 20 is fixedly connected to the surface of the sliding plate 21. The bottom of the support frame 2 is slidably connected to the top surface of the base plate 1. Guide grooves 22 are opened on the front and back sides of the top left and right sides of the base plate 1. Guide wheels 23 are embedded on the front and back sides of the bottom of the sliding plate 21. The guide wheels 23 are rotatably connected to the sliding plate 21. The guide wheels 23 are rollingly connected to the inner wall of the guide groove 22. When the conveyor rollers 3 on the left and right sides are conveying the conveyor belt, the operator can adjust the conveyor belt according to the tension of the conveyor belt. After the electric push rods 20 on the left and right sides are opened, the output shaft of the electric push rod 20 will push the sliding plate 21 to move, thereby making the entire support frame 2 move, adjusting the spacing between the conveyor rollers 3, and adjusting the tension of the conveyor belt. The guide wheels 23 roll inside the guide groove 22 to guide the support frame 2 and increase the stability of the support frame 2 when it moves.

[0027] Working principle: First, the operator starts the motor 51 in the adjustment structure 5 according to the width of the conveyor belt to be processed. The output shaft of the motor 51 drives the threaded rod 52 to rotate. Since the threads on the front and rear sides of the threaded rod 52 are opposite in direction, and the moving block 53 is restricted to horizontal movement only through the sliding connection between the limiting block 16 at its bottom and the limiting groove 15 at the bottom of the mounting box 4, the two moving blocks 53 move towards or away from each other on the threaded rod 52. The movement of the moving block 53 drives the processing frame 7 above to move synchronously through the connecting plate 6 that passes through the fixed groove 54, thereby adjusting the distance between the two drive motors 8 fixed on the processing frame 7 and the grinding discs 9 on their output shafts until they are precisely aligned. During this adjustment process, the bellows covers 17 fixed to the inner wall of the fixed groove 54 and the two sides of the connecting plate 6 extend and retract accordingly, effectively preventing grinding debris from falling into the mounting box 4 through the fixed groove 54 and protecting precision components such as the threaded rod 52 from contamination. The tension of the conveyor belt is adjusted by activating the electric push rods 20 at the four corners of the top of the base plate 1. The electric push rods 20 push the sliding plate 21 to move, causing the support frame 2 fixed to the sliding plate 21 and the conveyor rollers 3 on it to slide along the base plate 1, changing the distance between the left and right conveyor rollers 3. When the conveyor belt starts to move under the drive of the conveyor rollers 3 and passes through the processing station, if deviation occurs, the operator can activate the push structure 11 to correct the deviation. According to the direction of deviation, the corresponding mini cylinder 113 is activated. The output shaft of the mini cylinder 113 extends, driving the movable frame 112 to deflect at a certain angle relative to the fixed frame 111. This causes the support rod 12 fixed to the movable frame 112 and the correction frame 13 to undergo lateral displacement. The correction frame 13 pushes the side of the conveyor belt, forcing it to return to the center position, thus achieving real-time correction of the running trajectory. During the grinding and deburring process, the edge of the conveyor belt enters the interior of the processing frame 7. Under the continuous elastic force of the spring 18, the positioning plates 19 located on its upper and lower sides tightly adhere to the upper and lower surfaces of the conveyor belt, forming a flexible clamping area, which effectively suppresses the vertical jumping of the conveyor belt during the grinding process. The lateral movement greatly enhances the stability of the contact between the grinding disc 9 and the edge of the conveyor belt, thus ensuring the uniformity of the deburring quality. After the drive motor 8 starts, it drives the grinding disc 9 to rotate at high speed, grinding the accurately positioned edges of both sides of the conveyor belt to effectively remove the burrs. After the deburring process is completed, the conveyor belt continues to move to the cleaning structure 14 station. The cleaning brushes 143 on the upper and lower mounting plates 142 make close contact with the upper and lower surfaces of the conveyor belt. Under the action of friction, the debris and dust attached to the surface of the conveyor belt during the grinding process are thoroughly swept away to ensure the cleanliness of the conveyor belt surface, so as to meet the process requirements of subsequent processing or direct use, thereby completing the deburring operation of the conveyor belt.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
