Therefore, a sandpaper replacement system is proposed, which realizes sandpaper replacement by setting a grinding mill calibration mechanism, a sandpaper tearing mechanism, and a sandpaper feeding mechanism on the top of the table panel. The grinding mill calibration mechanism, the sandpaper tearing mechanism, and the sandpaper feeding mechanism are all individually fixed to the top of the table panel with bolts, which facilitates individual disassembly and replacement.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] The sandpaper replacement is achieved by installing a mill calibration mechanism, a sandpaper tearing mechanism, and a sandpaper feeding mechanism on the top of the table panel. Each of these mechanisms is individually bolted to the top of the table panel for easy disassembly and replacement. Figure 1-4 As shown, the sandpaper replacement system of this utility model includes a tool table 1 consisting of a workbench frame 101 and a table panel 102. The table panel 102 is located on top of the workbench frame 101. A mill calibration mechanism 2, a sandpaper tearing mechanism 3, and a sandpaper feeding mechanism 4 are sequentially arranged on the top of the table panel 102. The mill calibration mechanism 2 includes a detection mounting plate 201 fixed to the top of the table panel 102 by bolts. A linear bearing 202 is sleeved through the top of the detection mounting plate 201. A guide shaft 205 is sleeved through the inside of the linear bearing 202. A detection disc 204 is fixed to the top of the guide shaft 205 by bolts. A counterweight 206 is fixed to the bottom of the guide shaft 205 by bolts. A sensor bracket 207 is fixed to the bottom of the detection mounting plate 201 on one side of the guide shaft 205 by bolts.
[0023] The sandpaper feeding mechanism 4 includes an upper end plate 401 that is bolted to the top of the table panel 102. A lower end plate 407 is provided at the bottom of the upper end plate 401. Support rods 402 are equidistantly arranged between the lower end plate 407 and the upper end plate 401. Guide rods 405 are connected to the inner ends of the lower end plate 407 and the upper end plate 401 located between the support rods 402 through guide shaft support seats 403. A cylinder 404 is bolted to the bottom of the lower end plate 407. The output shaft at the top of the guide rod 405 passes through the lower end plate 407, and a lifting platform 408 is sleeved on the output shaft at the top of the lower end plate 407.
[0024] When in use, the mill rotates on the detection plate 204, and drives the counterweight 206 to rotate through the guide shaft 205. The external sensor detects the rotation, which facilitates the calibration of the mill. The cylinder 404 pushes the lifting platform 408 and the sandpaper placed on top of it to move up, so that it can be installed on the mill.
[0025] For example, such as Figure 3 As shown, the present invention also includes a sandpaper tearing mechanism 3, which includes a sandpaper tearing mounting plate 301 fixed to the top of the table panel 102 by bolts, and a sandpaper tearing sheet metal 302 fixed to the top of the sandpaper tearing mounting plate 301 by bolts.
[0026] When in use, the sandpaper removal mounting plate 301 makes it easy to remove the sandpaper from the mill.
[0027] For example, such as Figure 1 As shown, the present invention also includes an inspection door 103 provided on one side of the workbench frame 101, and a handle 106 fixed to one side of the inspection door 103 by bolts.
[0028] In use, the access door 103 can be pulled out using handle 106.
[0029] For example, such as Figure 1 As shown, the present invention also includes, at the bottom ends of both sides of the workbench frame 101, foot braces 104 are fixed by bolts, and at the bottom of the workbench frame 101 on one side of the foot braces 104, a mast wheel 105 is fixed by bolts.
[0030] In use, the foot brace 104 is used to support the workbench frame 101, and the fender 105 allows the workbench frame 101 to move.
[0031] For example, such as Figure 4 As shown, the present invention also includes the following: the top and bottom ends of the support rod 402 are respectively connected to the top of the lower end plate 407 and the bottom of the upper end plate 401 through polyurethane gaskets 406; the lifting platform 408 penetrates the upper end plate 401; and paddles 409 are equidistantly arranged on the outer side of the lifting platform 408.
[0032] When in use, the setting of the lever 409 makes it convenient for sandpaper placed on the lifting platform 408 to adjust the angle and position.
[0033] For example, such as Figure 1 As shown, the present invention also includes sandpaper feeding windows 5 provided at both ends of the top of the table panel 102.
[0034] When in use, removing the sandpaper feeding window 5 allows for the installation of sandpaper tearing mechanisms of other sizes on the tabletop 102.
[0035] When using this utility model, the operator connects the device to an external power source using a power cord. The external robotic arm moves the tray on its arm onto the sandpaper tearing mounting plate 301. The robotic arm moves so that the sandpaper tearing sheet metal 302 is inserted between the tray and the sandpaper. As the robotic arm moves, the sandpaper tearing sheet metal 302 scrapes the sandpaper off the tray. The sandpaper that falls off the tray falls into the workbench frame 101 through the holes on the sandpaper tearing mounting plate 301.
[0036] After the sandpaper falls off the tray, the external robotic arm is controlled to move the tray onto the detection plate 204 and control the tray to rotate. The rotation of the detection plate 204 drives the guide shaft 205 to rotate the counterweight 206 at its bottom end. The counterweight 206 is detected by ultrasonic sensors, infrared sensors, angle sensors and other sensors installed on the sensor bracket 207, and the angle of the tray is controlled to facilitate the subsequent installation of sandpaper and achieve the purpose of grinding mill calibration.
[0037] After the angle of the mill on the external robotic arm is adjusted, the external robotic arm controls the mill to move above the lifting platform 408. According to the angle, the sandpaper is placed on the lifting platform 408. The cylinder 404 is opened to push the lifting platform 408 and the sandpaper on top of it upward through the guide rod 405, so that the buckle on the sandpaper is inserted into the hole on the tray to install the sandpaper.
[0038] The foot brace 104 is used to support the workbench frame 101, the mast 105 facilitates the movement of the workbench frame 101, and the access door 103 allows the sandpaper to be torn off inside the workbench frame 101 for cleaning.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
