The upper surface of the tray plate is smooth and flat, 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. It is a flat four-way forking single-sided tray.

[0004] The moulding tray is made of straw, branch, wood chips, bamboo chips and bamboo fertilizer, which are recyclable resources. The production process usually adopts hot pressing and other methods. The raw materials and process are more environmentally friendly. Therefore, the moulding tray is increasingly occupying the theme of the tray market. The research on the moulding tray is becoming more and more intensive. How to better use environmentally friendly raw materials and how to improve the carrying capacity and strength of the tray are the key research directions of the moulding tray.

[0005] Compared with traditional plastic trays or wooden trays, the moulding tray has the advantages of environmentally friendly material, simplified manufacturing process, low manufacturing cost, small environmental pollution in manufacturing process and less post-manufacturing processing procedures. As for the tray itself, the moulding tray is made of crushed waste material, and the density of the compacted material is high. Compared with plastic trays, it has high pressure resistance and good wear resistance, and is more widely used. Compared with traditional wooden trays, the moulding tray undoubtedly has great advantages in material selection. The raw materials for the moulding tray are usually processing waste or crop waste, such as straw. Compared with wooden trays that need to cut trees for raw materials, the moulding tray not only reduces costs, but also meets the requirements of energy saving and environmental protection and protection of non-renewable resources.

[0006] After the mold pressing tray is pressed, burrs exist on the outer edge surface of the mold pressing tray, and the burrs need to be ground to obtain the final mold pressing tray product. At present, the grinding of the mold pressing tray is completed manually, and the manual processing is time-consuming and labor-consuming, low in efficiency and high in cost. Another grinding machine is used for grinding, and the grinding machine comprises a base for fixing the mold pressing tray and a grinding part for grinding. The fixing mode of the base for the mold pressing tray and the rotating mode of the base for driving the mold pressing tray will affect the grinding efficiency of the grinding part, and therefore, a high-efficiency tray base for the mold pressing tray grinding machine is needed. Content of the utility model

[0007] In view of the defects in the prior art, the fixing mode of the base for the mold pressing tray and the rotating mode of the base for driving the mold pressing tray will affect the grinding efficiency of the grinding part, and therefore, the utility model provides a tray base for a mold pressing tray grinding machine. The tray base comprises a base and a moving part. The base is provided with two layers. The upper base is provided with a groove, and the lower base can be fixed and positioned with the mold pressing tray. The lower base is provided with a sliding rail for sliding connection with the sliding block of the grinding part connecting piece. The moving part drives the base to rotate horizontally to drive the mold pressing tray to rotate horizontally through gear engagement transmission.

[0008] A tray base for a mold pressing tray grinding machine comprises a base and a moving part. The base is provided with a sliding rail for sliding connection with the sliding block of the grinding part connecting piece. The moving part drives the base to rotate horizontally to drive the mold pressing tray to rotate horizontally.

[0009] Further, the base comprises an upper base and a lower base. The sliding rail is arranged on the lower base. The track shape of the sliding rail is a rounded rectangle.

[0010] In some modes, the rounded rectangle is to change the four corners of the rectangle into a circle. The size of the rounded corner of the rounded rectangle can be realized by adjusting the radian of the rounded corner.

[0011] In some modes, the sliding rail is arranged in a rounded rectangle to facilitate the sliding of the sliding block at the turning corner.

[0012] In some modes, the mold pressing tray is generally a polygon. Taking a rectangular mold pressing tray as an example, when the grinding part grinds the edge of the mold pressing tray, the base fixes and drives the mold pressing tray to rotate horizontally, and the grinding part is relatively stationary. Therefore, the horizontal rotation of the base drives the sliding block of the grinding part to slide along the rounded rectangular rail in a cycle, so as to realize the grinding of the grinding part along the edge of the mold pressing tray.

[0013] Further, the upper base and the lower base are both in the shape of a rounded rectangle, and the size of the upper base is smaller than that of the lower base.

[0014] In some ways, the base is used to fix the mold pressing tray, and the edge grinding machine has a certain inclination angle with the base and the mold pressing tray when grinding the edge, which causes the edge grinding machine to contact the upper base when grinding the edge and affects the edge grinding efficiency if the size of the upper base is the same as that of the lower base.

[0015] Further, the upper base is provided with a groove matched with the protrusion of the mold pressing tray for fixing and positioning the mold pressing tray.

[0016] Further, the moving part comprises a driving device, a first gear and a second gear.

[0017] Further, the first gear is fixed with the lower base.

[0018] In some ways, the first gear drives the base to rotate, and then drives the mold pressing tray to rotate.

[0019] Further, the radius of the first gear is greater than that of the second gear, the first gear is engaged with the second gear, and the second gear drives the first gear to rotate by means of the driving device.

[0020] In some ways, the base rotation of the utility model is realized by the small gear driving the large gear, and the configuration of the small gear driving the large gear is the key mechanism to realize the speed reduction and torque increase. This configuration is based on the principle of gear transmission, that is, when the smaller diameter gear drives the larger diameter gear, the speed of energy transmission will be reduced accordingly. This is because the diameter of the gear is inversely proportional to its rotation speed, that is, the smaller diameter gear rotates faster, and the larger diameter gear engaged with it rotates slower, thereby achieving the effect of speed reduction. In addition, this configuration can also increase the torque, so that the mechanical system has greater power output at low speed. In the process of the small gear driving the large gear, although the small gear needs to overcome greater friction and input more energy, due to the decomposition of force, the actual acting force is smaller, so it can save more labor to improve work efficiency. In the utility model, the second gear is the small gear, and the first gear is the large gear. In this way, the small gear drives the large gear to rotate, thereby driving the mold pressing tray fixed to the tray base to rotate for edge grinding, which is efficient and energy-saving.

[0021] Further, the upper base and the lower base are fixed by a quadrangular prism, and the quadrangular prism comprises one or more.

[0022] Further, the number of grooves comprises one or more, which are uniformly distributed on the upper base.

[0023] Further, it also comprises a supporting column fixed with the first gear.

[0024] In some ways, the supporting column supports the entire tray base.
