Description

Technical Field

[0001] The utility model relates to the field of polishing equipment, and more specifically, to a glass frame polishing machine. Background Art

[0002] Glass is an amorphous inorganic non-metallic material. It is generally made of a variety of inorganic minerals, such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc. as the main raw materials, and a small amount of auxiliary raw materials. After the glass is made, it needs to be placed in a frame. The frame can protect the side walls of the glass. After the frame is completed, there may be burrs on the surface. Therefore, a polishing machine is needed to grind the surface of the frame.

[0003] Some existing glass frame polishing machines are not equipped with dust collection components. When polishing the glass frame, the polishing machine generates a large amount of dust. The dust floats in the air, which may pollute the air and degrade the working environment of the workers. Therefore, in order to solve the above problems, we propose a glass frame polishing machine.

[0006] By adopting the above technical solution, when the equipment is used, the staff places the product on the first conveyor belt, and the first conveyor belt conveys the product through the feed port into the support frame. The support frame is provided with a grinding component, which can play the role of grinding the product. When the grinding component grinds the product, dust will be generated. The operation of the dust suction and filtering component can absorb and filter the dust, which is beneficial to reduce the diffusion of dust. A clamping component is provided in the support frame to clamp and fix the product, which is convenient for stable grinding of the product, and the clamping component can move the product back and forth, which is beneficial to maintain the grinding effect and quality of the equipment. After the product is polished, the product can be conveyed by the second conveyor belt to move out of the support frame through the discharge port, which is convenient for the staff to take the material. Protective strips are provided in the feed port and the discharge port, which can close the feed port and the discharge port, which is beneficial to reduce the diffusion of dust and reduce the pollution of the equipment to the environment.

A mounting plate is provided above the frame, and a cylinder is fixedly mounted on the top of the support frame, and the cylinder piston shaft passes through the support frame and is fixedly mounted with a support block, and the bottom end of the support block is fixedly connected to the top end of the mounting plate, and a buffer assembly is provided between the bottom end of the mounting plate and the top end of the frame.

[0008] By adopting the above technical solution, when the product moves into the inside of the support frame, the cylinder drives the mounting plate, frame, first grinding roller, and first mounting box to descend synchronously, thereby adjusting the distance between the first grinding roller and the second grinding roller, so that the equipment can polish products of different sizes. When the distance between the first grinding roller and the second grinding roller is adjusted, the first reduction motor drives the first rotating rod and the first grinding roller to rotate synchronously, and the second reduction motor drives the second rotating rod and the second grinding roller to rotate. Through the cooperation of the first grinding roller and the second grinding roller, the product can be polished, and a buffer assembly is provided between the mounting plate and the frame. When the first grinding roller contacts the top of the product, the buffer assembly expands and contracts, thereby playing a buffering role, which helps to avoid damage to the product due to excessive descent of the first grinding roller.

[0010] By adopting the above technical solution, when the first grinding roller contacts the top of the product, the first grinding roller pushes the support rod to slide in the movable groove on the same side under the driving force of the cylinder, and the support rod pushes the spring on the same side to contract. The spring gives the support rod on the same side a rebound force, which can play a buffering role.

[0011] Furthermore, two symmetrically distributed sliding blocks are fixedly mounted on the top side walls of the two support rods, and the inner walls of the two movable grooves are provided with sliding grooves that match the sliding blocks in the same group.

[0012] By adopting the above technical solution, when the support rod slides in the movable groove, the support rod slides with the same group of sliders in the same side slide groove. The cooperation between the sliders and the slide grooves is conducive to maintaining the stability of the support rod sliding and helps to prevent the support rod from escaping from the same side movable groove.

[0013] Furthermore, the clamping assembly includes a screw that is rotatably installed in the installation groove, and the side walls of the two screws are sleeved with support blocks, and telescopic rods are fixedly installed on the opposite sides of the two support blocks, and clamps are fixedly installed on the ends of the two telescopic rods. Two symmetrically distributed protective boxes are fixedly installed on the side of the support frame close to the discharge port, and a third reduction motor is fixedly installed in the two protective boxes. The ends of the two screws close to the discharge port pass through the protective box on the same side, and the ends of the two screws close to the discharge port are fixedly connected to the end of the output shaft of the third reduction motor on the same side.

[0014] By adopting the above technical solution, when the product moves onto the second conveyor belt, the telescopic rod drives the splint on the same side to move, and the cooperation of the two splints can clamp and fix the product.

[0015] Furthermore, stabilizing blocks are fixedly installed on the top and bottom ends of the two support blocks, and grooves matching the stabilizing blocks on the same side are formed on the top inner walls and bottom inner walls of the two installation grooves.

[0016] By adopting the above technical solution, when the support block slides in the installation groove on the same side, the support block slides with the stabilizing block in the stabilizing groove on the same side. The cooperation between the stabilizing block and the stabilizing groove is conducive to maintaining the stability of the support block's movement.

[0017] Furthermore, the dust suction filter assembly includes a multi-way joint fixedly mounted on the top of the dust suction frame, a suction fan fixedly mounted on the top of the support plate, a filter frame fixedly mounted on the top of the support frame, a first duct is provided between one side of the filter frame and the multi-way joint, a second duct is provided between the side of the filter frame away from the first duct and the end opposite to the suction fan, filter cotton is slidably mounted on the side of the filter frame close to the second duct, a filter plate is slidably mounted in the filter frame, limit blocks are fixedly mounted on the top and bottom ends of the filter plate and the filter cotton, limit grooves are provided on the top inner wall and the bottom inner wall of the filter frame that match the limit blocks on the same side, a cover plate is fixedly mounted on one side of the filter frame, and a sealing gasket is provided on the inner wall of the cover plate.
