[0002] The grinding machine is used to trim the target parts by grinding, which is also one of the common methods used by manufacturers. There are many main materials for grinding machines, and the most commonly used ones are grinding wheels or abrasive belts. Abrasive belt grinders generally use two or more transmission rollers to drive the abrasive belts to rotate to achieve grinding.

[0003] Current grinders are generally operated manually by hand, and belt grinders require manual hand-held workpiece grinding due to their operating principle and ease of use. Such grinding will affect the accuracy of grinding, and the grinding point needs to be stared at for a long time, which may cause visual confusion and cause injuries to personnel. Therefore, a belt grinder is proposed. Utility Model Content

[0015] The utility model will be further described below in conjunction with the accompanying drawings.

[0016] Please refer to Figure 1-4 The utility model is a medium and thick plate sanding belt grinding machine, comprising a processing table 1, a concave-shaped column 2 is fixedly connected to the top of the processing table 1 and near the middle of the two end edges, a connecting column 3 is slidably connected to the bottom side wall of the column 2 opposite to the processing table 1, a lifting column 4 is telescopically inserted in the connecting column 3, a grinding belt 5 is set at the end of the lifting column 4 away from the connecting column 3, and two pressing plates 6 are set on the top of the processing table 1 and near the side wall of the column 2.

[0017] The lifting column 4 is fixedly connected to a fixed plate 9 at one end edge close to the grinding belt 5, and a rotating shaft 11 is fixedly connected to a side edge of the lifting column 4 away from the fixed plate 9, and a movable plate 10 is rotatably connected to the side wall of the rotating shaft 11. Side plates 8 are set on both sides of the pressing plate 6, and the movable plate 10 is clamped on the side plate 8 through the end away from the rotating shaft 11. The fixed plate 9 is fixedly connected to the top side wall of the side plate 8 on the other side. Adjustment holes 7 are evenly penetrated on the side walls of the connecting column 3 away from each other, and limit pins 14 are inserted and connected in the adjustment holes 7. The lifting column 4 is located at one end in the connecting column 3 and the edges away from each other are fixedly connected with a baffle 13, and the position of the baffle 13 corresponds to the end of the limit pin 14 located in the connecting column 3.

[0018] The technical effect of this solution is as follows: according to the size of the workpiece, the lifting column 4 is pushed into the connecting column 3, and the driver is started to drive the sanding belt to rotate at high speed via two rollers to grind the workpiece. Because the requirements of each workpiece are different, the grinding size is also different. Therefore, after the lifting column 4 is pushed into the connecting column 3, the limit pin 14 is inserted into different adjustment holes 7 according to actual requirements to position the lowerable size of the lifting column 4, thereby avoiding the problem of excessive grinding or repeated processing due to insufficient grinding size. The whole process does not require excessive human participation, which avoids the problem of accidents caused by staff staring at the grinding point for a long time.

[0019] A slider 12 is fixedly connected to the middle of the top side wall of the connecting column 3, and the slider 12 is a T-shaped structure. A slide groove is provided on the bottom side wall of the column 2, and the connecting column 3 is slidably connected in the slide groove through the slider 12. Two bottom grooves 15 are provided inside the processing table 1, and four springs 16 are evenly fixedly connected to the bottom side wall of the bottom groove 15. The pressing plate 6 is an L-shaped structure, and one end of the pressing plate 6 extends into the bottom groove 15 and is fixedly connected to the top of the spring 16. The bottom side wall of the pressing plate 6 opposite to the grinding belt 5 is inlaid with an anti-slip pad 17.

[0020] The technical effect of this solution is as follows: in order to ensure the stability of the workpiece, two pressing plates 6 are set up, and the workpiece is placed under the two pressing plates 6. The pressing plates 6 are pulled downward by the set springs 16 to press the workpiece to ensure its stability and avoid the workpiece from being deflected during the grinding process to affect the processing effect. The slider 12 is set up to move in the slide groove to realize the movement function, thereby improving the comprehensiveness of the grinding and increasing the processing range.

[0021] Specifically, when the utility model is used, the pressing plate 6 is driven by the driver to rotate at a high speed to grind and trim the workpiece. As the workpiece is ground, the lifting column 4 will gradually descend. When the lifting column 4 descends to the position limited by the limit pin 14, it will no longer descend, effectively avoiding excessive grinding and affecting the overall quality. In this way, there is no need for staff to observe the whole process, thereby avoiding safety accidents caused by long-term observation. When the grinding belt 5 needs to be replaced, the movable plate 10 is forcibly pried open and lifted along the rotating shaft 11, and the sanding belt is removed from the transmission roller. After the new sanding belt is replaced and the movable plate 10 is clamped on the side plate 8, in order to improve the stability of pressing, the pressing plate 6 is inlaid with an anti-slip pad 17 to increase the friction while avoiding wear on the workpiece. The slider 12 is controlled by the cylinder to move in the column 2, thereby increasing the processing range, and there is no need to manually move the workpiece, thereby improving the convenience of processing.

[0022] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0023] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
