Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, specifically to a surface grinding and polishing machine for profile connecting plates. Background Technology

[0002] After the profile connecting plate is cut, there are a lot of burrs on its edges, which need to be ground and polished. Among them, the roller polishing machine is a machine used for polishing and grinding materials. Its working principle is that the rotating roller drives the grinding material to rub against the surface of the workpiece, thereby achieving the effect of polishing and grinding.

[0003] However, after polishing the workpiece, the existing drum polishing machine requires all the grinding material and workpiece to be poured out and filtered before the grinding material is poured back into the polishing machine for subsequent processing. The operation steps are too cumbersome and it is not convenient to separate and remove the workpiece and grinding material, which greatly reduces the working efficiency of the device. Utility Model Content

[0004] The purpose of this utility model is to provide a surface grinding and polishing machine for profile connecting plates, so as to solve the problem mentioned in the background art that the grinding material and workpiece need to be poured out and filtered before the grinding material is poured back into the polishing machine for subsequent processing. The operation steps are too cumbersome and it is not convenient to separate and remove the workpiece and grinding material, which greatly reduces the working efficiency of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 An embodiment of this utility model provides a surface grinding and polishing machine for a profile connecting plate, including a polishing component 2. The polishing component 2 includes a polishing cylinder 21. One end of the polishing cylinder 21 is fixedly connected to a bushing 22, and the other end of the polishing cylinder 21 is fixedly connected to a rotating shaft 23. A filter screen plate 24 is fixedly connected to the inner wall of the polishing cylinder 21, and two guide screen plates 25 are symmetrically arranged on the surface of the filter screen plate 24.

[0022] Referring to the attached drawings, a motor 11 is fixedly connected to the top of the frame 1. The output shaft of the motor 11 is keyed to the bushing 22. The top of the frame 1 is rotatably connected to the bushing 22 and the rotating shaft 23 through bearing seats. A feeding plate 12 is fixedly connected between the frames 1. When the motor 11 is powered on and drives the polishing cylinder 21 to rotate, the internal workpiece and the grinding material rub against each other, completing the grinding and polishing of the workpiece surface. Through the setting of the filter screen plate 24 inside the polishing cylinder 21, when the polishing cylinder 21 rotates towards the non-connected end of the filter screen plate 24, the filter screen plate 24 can lift the workpiece and filter the grinding material to the bottom of the polishing cylinder 21, completing the filtration and separation of the two, which facilitates the individual removal of the workpiece, thereby effectively improving the convenience of the device's feeding, simplifying subsequent operation steps, and thus improving the efficiency of continuous operation of the device.

[0023] Furthermore, the polishing cylinder 21 has a hexagonal cross-section, and a discharge window is provided on one surface of the polishing cylinder 21. A sealing component 3 is provided on the outside of the discharge window of the polishing cylinder 21. The sealing component 3 is used to seal the discharge window to prevent material from falling out during rotation.

[0024] Furthermore, the filter screen 24 is fixedly connected to the inner wall of the panel with the discharge window. The minimum distance between the two guide screens 25 is less than the length of the discharge window. By setting the guide screens 25, the workpiece filtered by the filter screen 24 can be guided, so that when it is discharged, the workpiece is completely discharged through the discharge window, avoiding the workpiece getting stuck between the polishing cylinder 21 and the filter screen 24.

[0025] Furthermore, the sealing assembly 3 includes a material gate 31, one end of which is connected to a support shaft 37, and both ends of the support shaft 37 are fixedly connected to positioning seats 36. The positioning seats 36 are fixedly connected to the outer wall of the polishing cylinder 21, and the rotating end of the material gate 31 is arranged to the left and right of the connection end of the filter screen plate 24 and the polishing cylinder 21. The rotating end of the material gate 31 is in two directions from the connection end of the filter screen plate 24 and the polishing cylinder 21. Therefore, when the filtered workpiece is unloaded, the material gate 31 can be slightly pulled outward after the positioning is released, and the discharge window can be opened. At this time, the material gate 31 can block and guide the unloading of the workpiece, ensuring that the workpiece falls completely onto the unloading plate 12 for collection.

[0026] Furthermore, the sealing assembly 3 also includes a pressure plate 32 and a hinge seat 33. A rotating frame 34 is rotatably connected inside the hinge seat 33. A hand-tightening bolt 35 is threadedly connected to the center of the rotating frame 34. The pressure plate 32 is fixedly connected to the outer wall of the material gate 31. The hand-tightening bolt 35 abuts against the outer wall of the pressure plate 32. The length of the pressure plate 32 is greater than the length of the material gate 31. A handle is also fixedly connected to the outer wall of the pressure plate 32. Through the cooperation of the rotating frame 34 and the hand-tightening bolt 35, when the hand-tightening bolt 35 is rotated to the position where the pressure plate 32 is perpendicular, the pressure plate 32 can be squeezed by rotating the hand-tightening bolt 35, thereby squeezing and positioning the material gate 31. Conversely, the positioning of the material gate 31 can be released. Then, by pulling the material gate 31 outward by holding the handle, the material outlet can be opened and the material can be discharged.

[0027] Working Principle: The motors 11 used in this application are all commercially available products. Their principles and connection methods are well-known to those skilled in the art and will not be described in detail here. When using this utility model, the workpiece to be polished and the grinding material are first placed together inside the polishing cylinder 21. The polishing cylinder 21 is rotated by energizing the motor 11. The surface of the workpiece is polished by the friction between the grinding material inside and the surface of the workpiece. At this time, the rotation direction of the polishing cylinder 21 is towards the side where the filter plate 24 is connected to the polishing cylinder 21. When unloading, the motor 11 is rotated in the opposite direction. The rotation of the filter plate 24 can lift the workpiece inside the polishing cylinder 21 and filter the grinding material, so that the grinding material is retained inside the polishing cylinder 21. After releasing the locking and positioning of the material gate 31, the workpiece can be unloaded through the discharge window by opening the material gate 31.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
