Description

Technical Field

[0001] The utility model relates to the technical field of plastic turnover boxes, in particular to a processing positioning slotting structure for a plastic turnover box. Background Art

[0002] Turnover boxes, also known as logistics boxes, are widely used in machinery, automobiles, home appliances, light industry, electronics and other industries. They can be used to hold food, etc. They are easy to clean, and parts turnover is convenient, neatly stacked, and easy to manage. They are suitable for transportation, distribution, storage, circulation processing and other links in factory logistics. Turnover boxes can be used in conjunction with a variety of logistics containers and workstation equipment, and can be used in various warehouses, production sites and other occasions.

[0003] When the plastic turnover boxes are stacked, the positioning protrusion on the upper end of the plastic turnover box below is stuck in the positioning groove on the lower end of the plastic turnover box above. Such stacking can ensure that the plastic turnover boxes are stacked vertically and are not easy to tip over. Therefore, the positioning groove on the plastic turnover box is of great significance to the stable stacking of the plastic turnover boxes.

[0004] After the plastic turnover box is formed, a slotting machine is used to slot the plastic turnover box to form positioning slots. However, during the process, the loading of the plastic turnover box and the clamping and fixing before the slotting operation are mostly manual operations, resulting in poor stability of the plastic turnover box after clamping. During the slotting operation, the plastic turnover box is prone to position displacement. For this reason, we have introduced a plastic turnover box processing positioning slotting structure. Utility Model Content

[0005] The purpose of the utility model is to provide a plastic turnover box processing positioning slotting structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plastic turnover box processing positioning slotting structure, comprising a base, a conveyor belt for conveying the plastic turnover box is provided at the front of the upper end of the base, and a limit frame for limiting the plastic turnover box is provided at the rear of the upper end of the base;

[0007] A column is also provided at the rear of the upper end of the base, a first cylinder for driving the lifting seat to move up and down is installed on the top of the column, and the rear end of the lifting seat is slidably connected to the inside of the column through a connecting mechanism;

[0008] A second cylinder for driving the tensioning claw mechanism to open in the plastic turnover box is installed at the front upper end of the lifting seat, and after the tensioning claw mechanism is opened, it is close to the left and right inner walls of the plastic turnover box to fix the plastic turnover box.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the conveyor belt of the utility model conveys the plastic turnover box backwards until the plastic turnover box enters between the left and right sets of vertical plates, and the rear side of the plastic turnover box is attached to the horizontal plate, which is used to limit the backward movement of the plastic turnover box, so that the plastic turnover box can be loaded quickly;

[0010] Then the first piston rod of the first cylinder extends until the lifting seat descends to a suitable position, so that the tensioning claw mechanism enters into the plastic turnover box;

[0011] At this time, since both ends of the slide plate are slidably connected to the slide groove, the slider is slidably connected to the vertical groove, and the rollers provided on both sides of the slider are closely attached to the inner wall of the vertical groove, when the first cylinder drives the lifting seat to descend, the lifting seat can maintain horizontal descent, and the lifting seat moves more smoothly;

[0012] Then the second piston rod of the second cylinder extends out, causing the I-shaped connector to move downward, and then the I-shaped connector pushes the tensioning claw through the connecting rod to rotate and open around the first pin shaft, until the rubber pad at the bottom of the tensioning claw is in close contact with the inner wall of the plastic turnover box, so that the plastic turnover box can be tensioned and fixed, and the tensioning and fixing operation is simple and fast;

[0013] After the tensioning claws are opened, the plastic turnover box is tensioned and fixed to prevent the plastic turnover box from moving left and right, which is beneficial for keeping the plastic turnover box stable during subsequent slotting operations. BRIEF DESCRIPTION OF THE DRAWINGS
