[0015] Compared with the prior art, the beneficial effects of this utility model are: this automatic trimming mechanism applied to hook and loop sponge polishing enables automatic trimming of hook and loop sponge polishing, automatic feeding, and facilitates continuous trimming, thereby improving the trimming quality and efficiency of hook and loop sponge polishing. The specific details are as follows: 1. When trimming the edges of the hook and loop sponge polisher, stack the sponge polishers between the four support pillars. Two support plates will then support the bottommost sponge polisher. When loading the sponge polishers, activate the servo motors on the two movable frames on one side to adjust the height of the clamping cylinder. After adjustment, the clamping cylinder will move the clamping plate, clamping and fixing the second-to-last sponge polisher from the bottom. The upper sponge polishers will not move downwards; instead, they can be moved by the two servo motors on the other side. The feeding cylinder moves downwards, causing the bottommost hook and loop sponge to move along with the supporting plate. Then, the feeding cylinder can move the two supporting plates apart, allowing the bottommost hook and loop sponge to fall onto the conveyor belt through the feeding chute. The supporting plate then resets to support the remaining hook and loop sponges. Repeating these steps allows for continuous feeding of hook and loop sponges. Next, the drive motor is started, and the interaction between the drive and driven wheels rotates the conveyor wheel, causing the conveyor belt to rotate and transport the hook and loop sponges. The movement is controlled by the limit frame and limit plate. At this position, one end of the rotating frame on each of the two swing arm motors opens, allowing the hook and loop sponge to be conveyed to one side of the belt sander via a conveyor belt. Stopping the conveyor belt and starting the two adjusting motors allows adjustment of the positions of the two movable plates. Simultaneously, the electric cylinder adjusts the position of the movable plate, positioning the two rotating frames on either side of the hook and loop sponge. The swing arm motors drive the rotating frames to rotate, limiting the hook and loop sponge without clamping it. The belt sander then trims the hook and loop sponge. Simultaneously, starting the rotating motor, through the cooperation of the first and second pulleys, drives the rollers to rotate. The rollers move and engage with the hook and loop sponge, trimming it while the rollers rotate, causing the sponge to rotate further, allowing for continuous trimming of the outer side. The frame is equipped with a controller and display panel, allowing for programming to control the operation of various electrical components, enabling automatic trimming of the hook and loop sponge and automatic feeding, facilitating continuous trimming and improving the trimming quality and efficiency. 2. When trimming the hook and loop sponge, before the belt sander trims the hook and loop sponge, the stepper motor is started to drive the bidirectional threaded rod to rotate, bringing the two movable blocks closer together. This causes the rollers on the fixed rod to fit against the hook and loop sponge. The rollers and the two rollers limit the movement of the hook and loop sponge. Then, the electric push rod is started to move the connecting plate downward, so that the pressure plate abuts against the hook and loop sponge. The connecting plate continues to move downward, causing the sliding rod to slide on the connecting plate and compress the telescopic spring, which provides downward pressure to the hook and loop sponge. This prevents the hook and loop sponge from lifting or shifting during the trimming operation, thus improving the quality of the trimming process. Attached Figure Description

This can prevent the Velcro sponge polisher from curling up during the trimming operation.

[0022] Working principle: Before using this automatic trimming mechanism for polishing Velcro sponges, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 9 As shown, when trimming the hook and loop sponge, the hook and loop sponge is stacked between four support columns 204. At this time, the two support plates 212 can support the bottom hook and loop sponge. When loading the hook and loop sponge, the servo motors 207 on the two movable frames 206 on one side can be activated to adjust the height of the clamping cylinder 209. After adjustment, the clamping cylinder 209 can drive the clamping plate 210 to move, so that the clamping plate 210 clamps and fixes the second to last hook and loop sponge. At this time, the hook and loop sponge above will not move down. The loading cylinder 209 can be driven by the two servo motors 207 on the other side. 11. As the bottom hook and loop sponge ball moves downward along with the support plate 212, the two support plates 212 can be moved apart by the feeding cylinder 211, causing the bottom hook and loop sponge ball to fall onto the conveyor belt 113 through the feeding chute. The support plate 212 is then reset to support the remaining hook and loop sponge balls. Repeating these steps allows for continuous feeding of the hook and loop sponge balls. Then, the drive motor 110 is started, and the drive wheel 111 and driven wheel 112 work together to rotate the conveyor wheel 109, causing the conveyor belt 113 to rotate and transport the hook and loop sponge balls. The movement is controlled by the limit frame 104 and the limit plate 106. Positioning: At this point, one end of the rotating frame 319 on the two swing arm motors 318 opens, allowing the hook and loop sponge to be transported to one side of the belt sander 312 via the conveyor belt 113. Stopping the conveyor belt 113 and starting the two adjusting motors 303 adjusts the position of the two movable plates 302. Simultaneously, the electric cylinder 308 adjusts the position of the moving plate 309, positioning the two rotating frames 319 on either side of the hook and loop sponge. The swing arm motors 318 drive the rotating frames 319 to rotate, limiting the hook and loop sponge's position without clamping it. The belt sander 312 can then process the hook and loop sponge. During the trimming operation, the rotating motor 314 is started. Through the cooperation of the first pulley 315 and the second pulley 316, the roller 317 can be driven to rotate. The roller 317 moves and fits with the hook and loop sponge polisher. While trimming the hook and loop sponge polisher, the rotation of the roller 317 can make the hook and loop sponge polisher rotate, so that the outer side of the hook and loop sponge polisher can be continuously trimmed. The frame 1 is equipped with a controller and display panel. Through programming, the operation of various electrical components can be controlled, so that the hook and loop sponge polisher can be automatically trimmed and automatically fed, which facilitates continuous trimming and improves the trimming quality and efficiency of the hook and loop sponge polisher. During the trimming operation of the hook and loop sponge polisher, before the belt sander 312 trims the hook and loop sponge polisher, the stepper motor 321 is started to drive the bidirectional threaded rod 322 to rotate, so that the two movable blocks 323 come closer together, and then the rotating wheel 325 on the fixed rod 324 comes into contact with the hook and loop sponge polisher. The roller 317 and the two rotating wheels 325 can limit the hook and loop sponge polisher. Then, the electric push rod 329 can be started to drive the connecting plate 330 to move down, so that the pressure plate 332 abuts against the hook and loop sponge polisher. Then, the connecting plate 330 continues to move down, so that the sliding rod 331 slides on the connecting plate 330 and compresses the telescopic spring 333, which can provide downward pressure on the hook and loop sponge polisher. During the trimming operation, the hook and loop sponge polisher can be prevented from lifting up and shifting, thus improving the quality of the trimming process.
