Description

Technical Field

[0001] The utility model relates to the technical field of acrylic plate polishing equipment, in particular to a novel full-automatic acrylic polishing machine. Background Art

[0002] Acrylic sheet is a plastic material made from the polymerization of methyl methacrylate monomers. It boasts glass-like transparency and a wide range of colors. It is widely used in various industries, including construction, furniture, transportation, and electronics. For example, in the construction industry, it is used for windows and partitions; in furniture manufacturing, it is used as transparent panels or decorative elements; in the transportation sector, it is used in vehicle lighting systems; and in electronics, it is often used as screen protectors or touch panel materials.

[0003] In the prior art, acrylic sheets are produced by extruding PMMA particles into sheets through an extruder after melting them. The surface may not be smooth, so polishing equipment is required to grind and polish the acrylic sheets. However, due to the large number of sizes and specifications of acrylic sheets, different limit mechanisms need to be replaced to limit the acrylic sheets for acrylic sheets of different specifications, which has low applicability. At the same time, during the grinding process, the acrylic sheets may deform due to temperature changes, causing the acrylic sheets to shake in the limit mechanisms, affecting the grinding and polishing accuracy. Summary of the Invention

[0004] The purpose of the utility model is to provide a novel fully automatic acrylic polishing machine to solve the problems raised in the above background technology.

[0022] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a new fully automatic acrylic polishing machine, comprising: a frame 1, a guide rod 6 is symmetrically fixedly installed at the lower part of the frame 1, a fixed seat 8 is fixedly installed at the middle part of the outer periphery of the guide rod 6, a mobile frame 7 is slidably installed on both sides of the outer periphery of the guide rod 6, and a limit plate 9 is symmetrically fixedly installed on the top of the mobile frame 7, a rotating plate 12 is rotatably installed at the lower part of the fixed seat 8, and connecting rods 10 are rotatably installed on both sides of the rotating plate 12, and the connecting rods 10 are rotatably installed at one end away from the rotating plate 12 and the fixed seat 8, respectively rotatably installed at the lower part of the mobile plate on the same side, a guide rail 19 is symmetrically fixedly installed at the top of the frame 1, a fixed frame 4 is slidably installed in the middle part of the guide rail 19, a mounting plate 3 is fixedly installed on the top of the fixed frame 4, a cylinder 2 is fixedly installed in the middle part of the mounting plate 3, a polishing member 18 is provided at the driving end of the cylinder 2, a cylinder 2 11 is fixedly installed at the lower side of one side of the frame 1, and the driving end of the cylinder 2 11 is fixedly installed on the surface of the mobile frame 7 on the same side, An electric push rod 17 is symmetrically fixed on the upper part of the other side of the frame 1, and the driving end of the electric push rod 17 is fixed on one side of the fixed frame 4. The staff places the acrylic plate on the lower part of the frame 1 and controls the cylinder 2 11 to realize the movement of the movable frame 7 on the same side along the guide rod 6, and then the connecting rod 10 cooperates with the rotating plate 12 to drive the movable frame 7 on the other side to move, so that the limit plates 9 will be close to each other, and the acrylic plate will be limited and fixed. Since the spacing between the limit plates 9 can be adjusted, it can adapt to acrylic plates of different sizes and specifications, increasing the applicability of the device. Then, the cylinder 1 2 will drive the polishing part 18 to move downward until the polishing part 18 is in contact with the acrylic plate. At the same time, the electric push rod 17 will drive the polishing part 18 to move back and forth on the surface of the acrylic plate to achieve uniform polishing of the surface of the acrylic plate.

[0024] The stop plate 9 is provided with a spring 14 on its outer periphery, and one end of the spring 14 is fixedly mounted on the stop plate 13 on the same side, and the other end of the spring 14 is fixedly mounted on the stop plate 9 on the same side. The surface of the rubber plate 16 is provided with a plurality of evenly distributed anti-slip grooves. When the rubber plate 16 and the acrylic plate abut each other, as the stop plate 9 continues to move, the stop rod 15 will move in the stop plate 9, and the spring 14 will be compressed. When the acrylic plate is limited, the spring 14 will cooperate with the rubber plate 16 under the cooperation of its own elastic force, which can increase the limiting effect of the acrylic plate. At the same time, the rubber plate 16 can increase the friction between it and the acrylic plate, thereby preventing the acrylic plate from shaking during the polishing process and affecting the polishing effect.

[0025] The polishing part 18 includes a mounting frame, a grinding wheel and a driving member. The mounting frame is fixedly installed on the driving end of cylinder 1 2. The grinding wheel and the driving member are both arranged in the mounting frame. The driving member is used to drive the grinding wheel to rotate. A controller 5 is fixedly installed on the upper part of the other side of the frame 1. The controller 5 is electrically connected to cylinder 1 2, cylinder 2 11, the polishing part 18 and the electric push rod 17 respectively. By using the controller 5, the staff can drive the relevant components to operate accordingly. At the same time, the driving member in the polishing part 18 can be one of a stepping motor, a servo motor, etc. The driving member drives the grinding wheel to rotate, and the grinding wheel can polish the acrylic plate.

[0026] During actual use, the staff places the acrylic plate to be polished between the two sets of limit plates 9. By controlling the cylinder 2 11, the moving plate cooperates with the connecting rod 10 and the rotating plate 12 to control the spacing between the limit plates 9. At this time, the acrylic plate will be limited and fixed. With the cooperation of the abutment rod 15, the spring 14 and the rubber plate 16, the limiting effect of the acrylic plate can be increased. At the same time, the cylinder 1 2 can abut the polishing piece 18 on the acrylic plate to grind and polish the acrylic plate. With the cooperation of the electric push rod 17, the polishing piece 18 can move back and forth to evenly polish the acrylic plate. When one side of the acrylic plate is polished, the staff can turn the acrylic plate over and polish it again.

[0027] Although the above describes the illustrative specific implementation methods of the present application so that those skilled in the art can understand the present application, the present application is not limited to the scope of the specific implementation methods. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations based on the concept of the present application are protected.
