[0003] The full name of the molded tray is a plant fiber molded flat industrial tray. The raw materials commonly used in the molded tray are wood shavings, plant straws, bamboo wood, etc. It is a whole structure, and the panel and the supporting leg are molded and formed at one time. The upper surface of the tray plate is flat and smooth, which can meet the transportation of various goods. The lower surface is provided with reinforcing ribs. The vertical and horizontal stress of the plate surface is balanced, and the distribution of the nine legs can meet the four-way insertion of the forklift, which belongs to a flat four-way forking single-sided tray.

[0004] Because the molded tray is made of straw, branch, wood chips, bamboo chips, and bamboo fertilizer, which are recyclable resources, and the production process usually adopts hot pressing and other methods, the raw materials and process are more environmentally friendly. Therefore, the molded tray is increasingly occupying the theme of the tray market.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments described below are intended to facilitate the understanding of the present invention and do not constitute any limitation thereof.

[0034] Example 1: A sanding cloth fixing structure for an edge grinding machine

[0035] like Figures 1 to 4 As shown, a sanding cloth fixing mechanism for an edge grinding machine includes a sanding cloth 1, a bracket 2, a support column 3, a first roller 4, and a second roller 5. The sanding cloth 1 wraps around the first roller 4 and the second roller 5 to form a sanding cloth belt. One end of the bracket 2 is fixed to a baffle 8 via a connector 7, and the other end is fixed to the first roller 4. The bracket 2 can rotate and retract with the connector 7, thereby driving the first roller 4 to rotate. One end of the support column 3 is fixed to the baffle 8, and the other end is fixed to the bracket 2, serving to support the first roller 4. The support column 3 is detachable. When the support column 3 is detached, the bracket 2 loses its supporting force, and one end rotates and retracts around the connector 7. Since the other end of the bracket 2 is fixed to the first roller 4, the rotation and retraction of the bracket 2 drives the first roller 4 to rotate, causing the sanding cloth 1, which was originally in a taut state on the roller, to become loose. The first roller 4 is higher than the second roller 5, and the radius of the first roller 4 is smaller than the radius of the second roller 5. Furthermore, the line connecting the center of the first roller 4 and the center of the second roller 5 forms a certain angle with the horizontal line. This causes the abrasive cloth on the upper and lower sides of the rollers to be non-parallel and inclined to the horizontal plane. When the abrasive cloth 1 is working, it is positioned above the molding tray, and only the lower side of the abrasive cloth performs edge grinding. The angled inclination of the abrasive cloth 1 controls the contact area with the molding tray during edge grinding, reducing waste and extending the service life of the abrasive cloth 1. The drive device 6 is fixed to the second roller 5 and only drives the second roller 5 to rotate, thereby causing the abrasive cloth 1 to rotate.

[0036] Example 2: Method for replacing and operating the abrasive cloth

[0037] like Figure 5 As shown, when replacing the abrasive cloth, the support column 3 is removed from the baffle 8. At this time, the bracket 2 rotates clockwise around the connector 7 because it loses its support. At the same time, the first roller 4 also rotates clockwise with the bracket 2. The abrasive cloth 1 changes from a taut state to a loose state. The worn abrasive cloth can be removed from the roller, and the new abrasive cloth 1 is wrapped around the roller. The bracket 2 is rotated counterclockwise to make the abrasive cloth 1 change from a loose state to a taut state. The support column 3 is then reinstalled, and the abrasive cloth replacement is completed.

[0038] like Figure 6 As shown, the abrasive cloth 1 is mounted on the grinding component 11, positioned above the molding tray 9. Only the abrasive cloth 1 on the underside of the roller grinds the edge of the molding tray. The workpiece being ground by the abrasive cloth 1 is the molding tray 9, which is fixed to the tray base 10. When the abrasive cloth 1 grinds the edge of the molding tray 9, the drive device 6 rotates the abrasive cloth 1, causing the tray base 10 to rotate the molding tray 9 horizontally. Since the position of the grinding component 11 remains fixed, the position of the abrasive cloth 1 also remains fixed. The grinding of the edge of the molding tray 9 is achieved by the continuous horizontal rotation of the tray base 10, which in turn drives the molding tray 9 to rotate horizontally. To improve grinding efficiency, multiple grinding components 11 can be arranged around the tray base 10. In this embodiment 2, grinding components 11 are symmetrically arranged on both sides of the tray base 10.

[0039] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
