[0032] The polishing mechanism 4 includes a drive member 41 disposed on the adjusting support 32, a polishing belt 42 connected to the output end of the drive member 41, and a tensioning and buffering assembly 43 connected to the adjusting support 32. The drive member 41 is a motor, and the output end of the motor is connected to a driving wheel. The driving wheel is connected to the polishing belt 42 to drive the polishing belt 42 to rotate. The buffering assembly includes a buffering arm 431 rotatably connected to the adjusting support 32 at one end, a buffering wheel 432 disposed on the buffering arm 431, and a buffer 433 connected between the other end of the buffering arm 431 and the adjusting support 32. The buffering wheel 432 is connected to the polishing belt 42. Specifically, in the initial state, the buffer 433 provides tension to the polishing belt 42. During polishing, when the contact force between the product and the polishing belt 42 is too large, i.e., when the contact force exceeds the set force value of the buffer 433, the buffer 433 retracts. At this time, the buffering arm 431 rotates downward, causing the polishing belt 42 to loosen, thereby preventing the contact force between the polishing belt 42 and the product from being too large. In this embodiment, the buffer 433 can be a spring rod.

[0033] The adjusting support 32 includes an adjusting seat 321 connected to the support seat 31, a fixing seat 322 connected to the adjusting seat 321, and a fixing plate 323 connected to the fixing seat 322.

After adjusting the adjusting seat 321 to the appropriate angle, the locking bolts can fix the adjusting seat 321 at the current angle. By adjusting the angle of the adjusting seat 321, the inclination angle of the polishing belt 42 relative to the horizontal plane can be changed, thereby meeting the polishing needs of different products.

[0034] The polishing mechanism 4 includes a tensioning assembly 44, which includes a tensioning bracket 441 connected to the adjusting bracket 32, and a tensioning wheel 442 connected to the tensioning bracket 441. The tensioning wheel 442 is connected to the polishing belt 42. The cooperation of the tensioning wheel 442, the buffer wheel 432, and the drive wheel makes the polishing belt 42 present a triangular structure.

[0035] The fixing seat 322 is provided with a connecting groove 325, and the tensioning bracket 441 is connected to the connecting groove 325. The tensioning bracket 441 can move relative to the connecting groove 325, thereby adjusting the length of the tensioning bracket 441 extending out of the fixing seat 322 to change the tension of the polishing belt 42. After adjusting to a suitable position, the fixing seat 322 and the tensioning bracket 441 can be locked together using fasteners.

[0036] The belt polishing device includes a pressure detection mechanism 5, which includes a pressure detection bracket 51 mounted on the base 1, a pressure sensor 52 mounted on the pressure detection bracket 51, and a pressure detection element 53 mounted on the floating plate 3 that matches the pressure sensor 52. (See attached image.) Fig. 1 Taking the product as an example, when it contacts the polishing belt 42 from the front, and the floating plate 3 moves backward due to the contact force, the pressure detection component 53 applies a force to the pressure sensor 52. The pressure sensor 52 monitors the magnitude of this force and feeds it back to the equipment's control system. The control system analyzes and judges the received force data according to the set force range and makes timely adjustments, such as adjusting the position of the slider 23 of the floating mechanism 2 or slightly moving the product away from the polishing belt 42, to reduce the contact force. The cooperation between the pressure detection mechanism 5 and the tension buffer assembly 43 minimizes the contact force between the product and the polishing belt 42 during the polishing process, thereby ensuring that the product does not wear excessively and ensuring product quality and yield.

[0037] The belt polishing device includes a limiting component 6, which comprises a limiting plate 61 disposed on the base 1, a limiting member 62 disposed on the floating plate 3, and a limiting adjustment member 63 disposed on the limiting member 62. The floating plate 3 has a through hole 33, through which the upper end of the limiting plate 61 passes, and the limiting plate 61 is closer to the center of the base 1 than the limiting member 62.

On the other hand, under the cooperation of the adjusting seat 321 and the fixed seat 322, the inclination angle of the polishing belt 42 relative to the horizontal direction can be adjusted, so that the processing requirements of different products can be flexibly met.
