Description

Technical Field

[0001] This utility model relates to a double-sided polishing device for rectangular glass. Background Technology

[0002] After glass production and cutting, the edges are quite sharp, so the cut glass usually needs to be ground. An edging machine is a commonly used piece of machinery for grinding glass. Edge grinding eliminates the sharp edges, reducing the risk of accidental injury; it also makes the edges smoother, more aesthetically pleasing, and improves the overall quality. Existing edging devices generally use rotating rollers to move the glass. During the transfer process before entering the edging machine, glass vibration, slippage, and human error often cause changes in the glass's position, resulting in inaccurate positioning and unnecessary damage during the edging process. Utility Model Content

[0003] To address the shortcomings mentioned above, this utility model provides a double-sided polishing device for rectangular glass.

[0004] To achieve the above objectives, this utility model provides a double-sided polishing device for rectangular glass, comprising two conveyor chains arranged parallel to each other in the horizontal direction. The conveyor chains are rotatably mounted with rollers to form an integral structure. The rollers are evenly distributed along the length of the conveyor chains. The glass is placed on the rollers and moves evenly from left to right. Limiting blocks are provided at intervals on the conveyor chains to limit the glass to the left. Guide plates are provided at the front and rear of the middle of the conveyor chains to align the front and rear positions of the glass. A grinding mechanism is provided on the right side of the glass, and a grinding wheel is provided in the middle of the grinding mechanism to correspond to the edge of the glass.

[0005] As a further improvement of this utility model, the roller is unpowered and the surface of the roller is higher than the conveyor chain.

[0006] As a further improvement of this utility model, rollers are installed after the two ends of the roller shaft pass through the links of the conveyor chain. Side baffles are provided on the front and rear sides of the conveyor chain along the length direction. Guide grooves are machined on the upper part of the side baffles. The lower part of the rollers is embedded in the guide grooves to form a rolling fit. The width of the glass is greater than the distance between the side baffles.

[0007] As a further improvement of this utility model, the limiting block is fixed to the corresponding chain link by an L-shaped bracket, and the distance between adjacent limiting blocks is greater than the length of the glass.

[0008] As a further improvement of this utility model, the guide plate includes an integrally connected inclined section and a straight section. The distance between the inclined sections gradually decreases from left to right, and the distance between the straight sections matches the width of the glass. The end of the straight section extends to the left side of the edge grinding mechanism.

[0009] As a further improvement of this utility model, the rotation direction of the grinding wheel is opposite to the movement direction of the conveyor chain.

[0010] The beneficial effects of this utility model are as follows:

[0011] The device uses a non-powered roller to place the glass, with the glass and the conveyor roller remaining relatively stationary. The conveyor chain drives the roller and the glass to move horizontally. The conveyor chain is equipped with a limit block to limit the glass to the left, and guide plates are provided on the front and rear sides of the conveyor chain to align the front and rear positions of the glass. The glass is not prone to vibration or slippage before entering the edging mechanism, ensuring accurate positioning and preventing damage during edging. Rollers are provided at both ends of the roller, and the lower part of the roller is fitted into the guide groove of the side baffle. When the conveyor chain drives the roller to move, the roller rolls along the guide groove, which also provides support for the glass and ensures the levelness of the glass.

[0017] like Figure 1-4As shown, the double-sided polishing device for rectangular glass of this utility model includes two parallel conveyor chains 1 arranged horizontally. Rollers 2 are rotatably mounted between the conveyor chains 1 to form an integral structure. The rollers 2 are evenly distributed along the length of the conveyor chains 1. Glass 3 is placed on the rollers 2 and moves evenly from left to right. The rollers 2 are unpowered, and their surfaces are higher than the conveyor chains 1. Rollers 21 are installed at both ends of the rollers 2 after passing through links 11 of the conveyor chains 1. Side baffles 5 are provided along the length of the conveyor chains 1. Guide grooves 51 are machined on the upper part of the side baffles 5, and the lower parts of the rollers 21 are embedded in the guide grooves 51 to form a rolling fit. The width of the glass 3 is greater than the distance between the side baffles 5. Limiting blocks 4 are spaced apart on the conveyor chains 1 to form left and right positions on the glass 3. Limiting blocks 4 are fixed to corresponding chain links 11 via L-shaped brackets 41. The distance between adjacent limiting blocks 4 is greater than the length of glass 3. Guide plates 6 are provided at the front and rear of the middle of the conveyor chain 1 to align the front and rear positions of glass 3. The guide plate 6 includes an integrally connected inclined section 61 and a straight section 62. The connection between the inclined section 61 and the straight section 62 adopts an arc transition. The distance between the inclined sections 61 gradually decreases from left to right. The distance between the straight sections 62 matches the width of glass 3. The end of the straight section 62 extends to the left side of the edge grinding mechanism 7. The edge grinding mechanism 7 is provided on the right side of glass 3. The edge grinding mechanism 7 is provided in the middle of the edge grinding mechanism 7, which corresponds to the edge of glass 3. The rotation direction of the edge grinding wheel 71 is opposite to the movement direction of the conveyor chain 1.

[0018] The device uses a non-powered roller to place the glass, with the glass and the conveyor roller remaining relatively stationary. The conveyor chain drives the roller and the glass to move horizontally. The conveyor chain is equipped with a limit block to limit the glass to the left, and guide plates are provided on the front and rear sides of the conveyor chain to align the front and rear positions of the glass. The glass is not prone to vibration or slippage before entering the edging mechanism, ensuring accurate positioning and preventing damage during edging. Rollers are provided at both ends of the roller, and the lower part of the roller is fitted into the guide groove of the side baffle. When the conveyor chain drives the roller to move, the roller rolls along the guide groove, which also provides support for the glass and ensures the levelness of the glass.

[0019] For ease of understanding, this utility model will be described in conjunction with the accompanying drawings for practical use:

[0020] During operation, the glass is placed on the rollers between the conveyor chains. The left side of the glass can rest against the limiting block or not. The conveyor chain drives the rollers and the glass to move synchronously. The surfaces of the glass and the rollers are relatively stationary. The rollers at both ends of the rollers roll along the guide grooves on the upper part of the side baffles. When the glass moves between the guide plates, the guide plates align the front and back positions of the glass. After passing the guide plates, the glass enters the edging mechanism. The edging wheels on both sides of the glass simultaneously edge the edges of the glass. During the edging process, the edging wheels exert a leftward thrust on the glass. There are two possibilities: when the left side of the glass has already rested against the limiting block, the limiting block will exert a rightward thrust on the glass, causing the glass to move to the right to complete the edging process; when the left side of the glass has not yet contacted the limiting block, since the rollers are not powered, the glass will first roll relative to the rollers. After the left side of the glass rests against the limiting block, the thrust of the limiting block will push the glass through the edging wheels, thus completing the edging process.

[0021] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
