[0002] A sanding machine is a power tool that sands and polishes the surfaces of wood, metal, etc. through a high-speed rotating grinding wheel or sand belt to make them smoother and brighter. The sanding machine is widely used in woodworking, metal processing and other fields and has become a powerful tool for sanding processing. Its working principle is that through a high-speed rotating grinding wheel or sand belt, the abrasive grains rub against the surface of the workpiece to achieve the sanding effect.

[0003] During the process of plate processing, it is usually necessary to use a sanding machine to sand the uneven outer wall of the plate to make the outer wall of the plate smoother, flatter and the thickness uniform, so as to meet the needs of subsequent processing. In the prior art, most sanding machines cannot automatically feed the plates. Before processing the plates, it is necessary to manually push the plates into the sanding machine. This process is not only time-consuming and laborious, but also reduces the processing effect of the sanding machine on the plates, and the practicability is insufficient. Therefore, it is necessary to redesign a high-efficiency plate sanding machine for the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and provide a high-efficiency plate sanding machine for grinding plates.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A high-efficiency plate sanding machine includes a sanding machine body. A placing plate is fixedly installed on the upper end surface of the sanding machine body.

A first motor connected to the rotating shaft is fixedly installed on the outer wall of one of the support plates. A plurality of spring telescopic rods are fixedly installed on the outer wall of the rotating shaft through an installation mechanism. A dial block is fixedly installed at the telescopic end of each spring telescopic rod. A moving frame is fixedly installed on the outer wall of the sanding machine body through an installation groove. A double-headed screw rod is rotatably installed inside the moving frame. A second motor connected to the double-headed screw rod is fixedly installed on the outer wall of the moving frame. Two moving blocks are threadedly installed on the outer wall of the double-headed screw rod through a limiting mechanism. The upper end surfaces of the two moving blocks are fixedly connected with positioning frames through a connection mechanism.

[0011] Preferably, a plurality of positioning rollers are rotatably installed inside both positioning frames, and each positioning roller and each dial block are made of rubber.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. By arranging components such as a rotating shaft, a spring telescopic rod, and a dial block, when the rotating shaft rotates, the dial block can be driven to rotate through the cooperation of the mounting sleeve and the spring telescopic rod. Thus, the dial block can be used to dial the plate to achieve automatic feeding.

A plurality of installation grooves are opened on the upper end surface of the placement plate 2. A guide roller 3 is rotatably installed inside each installation groove. The upper end surface of the placement plate 2 is rotatably installed with a rotating shaft 5 through two support plates 4. A first motor 6 connected to the rotating shaft 5 is fixedly installed on the outer wall of one of the support plates 4. A plurality of spring telescopic rods 8 are fixedly installed on the outer wall of the rotating shaft 5 through a mounting mechanism. The mounting mechanism includes a mounting sleeve 7 fixedly installed on the outer wall of the rotating shaft 5. Each spring telescopic rod 8 is fixedly installed on the outer wall of the mounting sleeve 7. A dialing block 9 is fixedly installed at the telescopic end of each spring telescopic rod 8.

[0024] When the utility model is used, a plate can be placed on the upper end surface of the placement plate 2. At this time, the first motor 6 can drive the rotating shaft 5 to rotate. The rotating shaft 5 drives the multiple spring telescopic rods 8 to rotate through the cooperation of the installation sleeve 7, thereby the spring telescopic rods 8 can drive the shifting block 9 to rotate, so that the plate can be shifted by the multiple shifting blocks 9, so that the plate can be moved on the upper end surface of the placement plate 2 through the cooperation of the multiple guide rollers 3, so as to realize the automatic feeding of the plate during grinding, improve the grinding efficiency of the plate by the sanding machine body 1, and in the process of automatic feeding, the extension distance of the shifting block 9 can be elastically adjusted through the elastic action of the spring telescopic rod 8, so that the shifting block 9 can be used to shift and feed plates of different thicknesses;

[0025] At the same time, the second motor 12 can drive the double-headed screw 11 to rotate, and the double-headed screw 11 drives the two moving blocks 14 to move by cooperating with the limit rod 13. The two moving blocks 14 then drive the positioning frames 16 on the same side to move through the cooperation of the connecting rod 15, so that the positioning frames 16 on both sides can be close to each other, and the plate can be clamped and positioned by multiple rotatably installed positioning rollers 17 on both sides to avoid the plate from shifting during the loading process and preventing the sanding machine body 1 from affecting the grinding operation thereof. Since each positioning roller 17 is rotatably installed, it will not affect the normal loading of the plate, and under the drive of the double-headed screw 11, the spacing between the two positioning frames 16 can be conveniently adjusted to clamp and position plates of different widths.
