Description

Technical Field

[0001] The utility model relates to a tray, in particular to a high-strength plastic tray. Background Art

[0002] In tire production, the stacking and transfer of green tires need to be strictly controlled to avoid bump damage, which affects the quality of the post-vulcanized finished products. Traditionally, green tires are mostly placed separately on a flat plate or platform, which is not convenient for indicating and distinguishing various information of their previous production, and the planar support structure is not conducive to safe and stable transfer and is not convenient for efficient production. For this reason, the applicant previously developed a tray with the patent number 202022737628.3, which adopts a square tray body with a bottom cover structure. However, during nearly three years of sales and use, the upper end face, inner end face, outer side face and inner side face of the square tray have complex structures, low production yield, and high cost. The bottom cover is under the downward pressure supported by the central tire for a long time, and the screw holes of the connecting columns are prone to thread slipping, resulting in loosening and damage of the tray connection structure, affecting the use quality and safety. Moreover, during actual production line conveying, there are collisions between the tray and the production line track and between trays, directly affecting the use performance and service life of the tray. Summary of the Invention

[0003] The utility model provides a high-strength plastic tray with a simple structure, convenient processing, low production cost, safe use and long service life.

[0004] The technical solution adopted by the utility model is: a high-strength plastic tray, which is characterized in that it includes a square tray body integrally injection-molded. The inside of the square tray body is hollowed out and the upper end is open and sealed by an overall upper cover. The upper end face of the overall upper cover is provided with a concave structure, and the concave structure includes a central circular flat bottom and a side annular spherical surface. The side annular spherical surface is provided with a linearly arranged anti-slip concave rib groove diverging from the center, and the side annular spherical surface is also evenly distributed with a plurality of vertical sinks around the center. The center of the four side edges of the square tray body is provided with a downward-opening positioning groove. One side or multiple sides of the four sides of the square tray body are provided with chip holes, and a tire processing information chip is placed in the chip holes. The four side edges of the square tray body are provided with anti-collision installation grooves and / or anti-collision installation holes on both sides of the positioning groove, and the anti-collision installation grooves and / or anti-collision installation holes are externally connected with anti-collision heads exceeding the side edges.

[0005] A plurality of vertical side strengthening ribs and a plurality of vertical side connecting columns are evenly distributed in the inner cavity of the side wall of the square tray body, and the side connecting columns pass through the upper connecting holes of the overall upper cover and are locked and connected to the overall upper cover by screws.

[0006] A plurality of vertical intermediate connecting columns are evenly distributed on the bottom surface of the inner cavity of the square tray body, and the intermediate connecting columns pass through the upper connecting holes of the overall upper cover and are locked and connected to the overall upper cover by screws.

[0007] The lower end face of the overall upper cover is evenly provided with a reinforcing rib group.

[0008] The reinforcing rib group is staggered from the middle connecting column.

[0009] The reinforcing rib group includes a central reinforcing rib group and a peripheral reinforcing rib group. The central reinforcing rib group includes multiple circumferential reinforcing ribs with different diameters and concentric circles and radially diverging radial reinforcing ribs evenly distributed in the circumferential direction. The peripheral reinforcing rib group is multiple peripheral reinforcing ribs that cross to form a square structure. The maximum diameter of the circumferential reinforcing rib does not exceed the vertical projection of the concave structure.

[0010] Four corner-pulling reinforcing ribs are also provided on the lower end surface of the integral upper cover, and the corner-pulling reinforcing ribs connect the four corners from the center.

[0011] Using an integral upper cover to encapsulate a square disk body with an upper opening, the integral injection molding of the square disk body and the integral upper cover is simple, the production is convenient, the cost is low, the finished product rate is high, and the quality is stable; the locking structure on the integral upper cover improves the locking stability and firmness of the connecting column, and can effectively ensure the use quality and service life; anti-collision heads are arranged around the square disk body, and the anti-collision heads can be made of the same material as the square disk body or other flexible materials, which can avoid the collision of the whole tray with the track or each other during transportation and improve the use performance.
