[0039] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the application.

[0040] As Figures 1 to 3As shown, a sand belt pressure device 300 comprises: an electric linear guide rail 2, a moving frame 3, a lifting frame 4, a driving part 5, an adjusting frame 6, a pressing part 7, the electric linear guide rail 2 has a sliding block 21; the moving frame 3 is fixed on the sliding block 21; the lifting frame 4 is slidingly arranged on the moving frame 3; the driving part 5 is connected with the lifting frame 4, and is used to drive the lifting frame 4 to move close to or away from the moving frame 3; the adjusting frame 6 is connected with the lifting frame 4 through an elastic telescopic assembly 8; the pressing part 7 is detachably connected with the adjusting frame 6, and the pressing part 7 has a pressing structure 72 which is adapted to the surface shape of the plate material, and the pressing structure 72 is used to contact the sand belt 100 and make the sand belt 100 abut against the surface of the plate material.

[0041] In this application, in the case of large flat plate material, after the electric linear guide rail 2 is powered on and started, the sliding block 21 starts to move. Since the moving frame 3 is fixed on the sliding block 21, the moving frame 3 will move along with the sliding block 21 on the electric linear guide rail 2 to adjust the position in the horizontal direction. Through the telescopic movement of the driving part 5, the lifting frame 4 is driven to slide on the moving frame 3 in the vertical direction, so as to adjust the height of the lifting frame 4. The pressing structure 72 of the pressing part 7 can contact the sand belt 100 and press the sand belt 100 against the surface of the plate material. Through the continuous back-and-forth movement of the pressing part 7, the surface of the large flat plate material can be polished.

[0042] The elastic telescopic assembly 8 can play a buffering role.

[0043] The pressing part 7 and the adjusting frame 6 are detachably connected. When the pressing part 7 is worn or needs to be replaced by a different type to adapt to different plate materials, for example, the flat plate is replaced by a special-shaped plate, the pressing part 7 can be conveniently and quickly detached from the adjusting frame 6 for replacement.

[0044] According to the width of the plate material, the moving direction of the moving frame 3 driven by the electric linear guide rail 2 can be adjusted. In the case of special-shaped plate material, the electric linear guide rail 2 remains in a state of not moving.

[0045] The device can not only polish the large flat plate material, but also can be flexibly moved and accurately adjusted in height on a large area of flat plate by the cooperation of the electric linear guide rail 2 and the lifting frame 4. In addition, the pressing part 7 can be replaced at any time, so as to realize high-quality sanding of special-shaped plate material. The device effectively solves the problem that the existing equipment cannot consider different types of plate materials, and greatly expands the application range of the device.

[0046] Specifically, the driving part 5 is a pneumatic cylinder. In addition, a push rod motor can also be selected as an alternative, but the pneumatic cylinder has a lower cost, so the pneumatic cylinder is preferred.

[0047] Specifically, the elastic telescopic assembly 8 comprises a plurality of sliding rods 81 and a plurality of springs 82, the sliding rods 81 are fixed on the adjusting frame 6, the lifting frame 4 is provided with guide holes, the sliding rods 81 are inserted into the guide holes and can slide, and the springs 82 are sleeved on the sliding rods 81 and abut against the lifting frame 4 and the adjusting frame 6 at both ends.

[0048] The plurality of sliding rods 81 work cooperatively with the springs 82, so that the elastic telescopic assembly 8 has excellent buffering performance, and a positioning function is started, so that the elastic telescopic assembly 8 can only be lifted.

[0049] Specifically, the end of the sliding rod 81 is fixed with a limiting part 811, the sliding rod 81 passes through the guide hole, and the limiting part 811 can abut against the lifting frame 4 to limit the sliding rod 81 from disengaging from the guide hole.

[0050] During the operation of the device, due to the high-speed operation of the abrasive belt 100 and the cooperative movement of the parts of the device, unstable factors such as vibration and impact may occur, and the limiting part 811 can limit the guide rod from disengaging.

[0051] Specifically, the adjusting frame 6 is provided with a mounting part 61, a through hole 611 is formed in the mounting part 61, and a mounting sliding groove 612 is further arranged on the mounting part 61, and the through hole 611 is arranged in the middle of the mounting sliding groove 612; a positioning rod 62 is inserted into the through hole 611, and the positioning rod 62 is connected with the mounting part 61 through a tension spring 63, so that the lower end of the positioning rod 62 passes through the through hole 611, the sliding part 71 matched with the mounting sliding groove 612 is arranged on the extrusion component 7, the positioning hole 711 is formed in the sliding part 71, and the positioning rod 62 can be inserted into the positioning hole 711.

[0052] Under the action of the tension spring 63, the positioning rod 62 always has a tendency to be inserted downward into the positioning hole 711, so that the connection between the extrusion component 7 and the adjusting frame 6 is stable, and in the process of high-speed operation of the abrasive belt 100 for polishing the plate, a large friction force and vibration will be generated, and this stable connection mode can effectively resist these external forces, so that the extrusion component 7 will not be displaced or loosened, and the abrasive belt 100 can always be attached to the surface of the plate at a correct angle and pressure, so that stable and efficient sanding work is maintained.

[0053] When the extrusion component 7 needs to be replaced, the positioning rod 62 is only needed to be pulled out, and then the extrusion component 7 is slid out, and then another extrusion component is slid and assembled in the mounting sliding groove 612 until the positioning rod 62 is inserted into the positioning hole 711.

[0054] Further, the positioning hole 711 is matched with the diameter size of the positioning rod 62, so as to limit the movement of the extrusion component 7.

[0055] Specifically, the end of the positioning rod 62 away from the extrusion component 7 is provided with a pull ring 621.

[0056] The setting of the pull ring 621 provides a convenient gripping force point for an operator, when the extrusion part 7 needs to be disassembled, the operator does not need to use additional tools to pull the positioning rod 62, only needs to hook the pull ring 621 with fingers, and the positioning rod 62 can be easily pulled up to make the positioning rod 62 disengage from the positioning hole 711.
