Description

Technical Field

[0001] This utility model relates to the field of tea packaging, and in particular to a four-legged inward folding device for a paper box during the tea boxing process. Background Technology

[0002] Packaging boxes are needed for tea packaging. For example, bagged tea is packaged in a box.

[0003] For boxed tea, a six-sided cardboard box is generally used, which needs to be folded into shape. When boxing bagged tea, the cut cardboard board is first folded into an unsealed box shape, then the bagged tea is put into the cardboard box, glue is applied to the sealing side of the cardboard box, and finally the glued side of the cardboard box is sealed, thus completing the boxing of bagged tea.

[0004] When the bagged tea enters the bottom area of ​​the cardboard box during the folding process, the four corners need to be folded inward first, and then the rest of the cardboard box is folded accordingly to finally form the box.

[0005] If the four corners of the cardboard box are folded inward manually during the tea packaging process, there will be problems such as low automation, high labor costs, high labor intensity, and low boxing efficiency. Summary of the Invention

[0006] The purpose of this utility model is to provide a paper box four-leg inward folding device in the process of tea boxing, which can solve the problems of low automation, high labor cost, high labor intensity and low boxing efficiency in the existing technology where the four-leg inward folding of paper boxes is achieved manually.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: a four-legged inward folding device for tea box packaging, including a frame, a conveyor belt set on the frame, a set of paper box placement areas on the conveyor belt, and placement platforms on both sides of the frame. An auxiliary support is set on the placement platform, and a rotatable shaft is set on the auxiliary support. The shaft is mounted above the conveyor belt, and a front actuating block and a rear actuating block are set on the shaft. The front actuating block is located at the front of the paper box placement area and is adapted to the front left leg of the paper box. The rear actuating block is located at the front of the paper box placement area. The rear side is adapted to the rear left foot of the cardboard box; a drive device for driving the rotating shaft is provided on the placement platform; a bending plate is also provided on the front and rear sides of the workbench on the conveyor belt, and the bending plate is located on the right side of the front actuating block and the rear actuating block; a clearance gap adapted to the cardboard box is provided between the bottom of the bending plate and the placement platform; the bending plate includes a straight plate part and a curved plate part, the straight plate part is set close to the outer wall of the cardboard box placement area, and the curved plate part is set at the end of the straight plate part facing the auxiliary support and is turned outward in the direction away from the conveyor belt; the front actuating block and the rear actuating block are adapted to the curved plate part on the corresponding side.

[0008] Furthermore, the driving device includes a toggle cylinder hinged to the mounting platform, and a toggle rod connected to the piston part of the toggle cylinder is provided at one end of the rotating shaft.

[0009] Furthermore, each bending plate on the frame is provided with a mounting seat, and a positioning plate is provided on the mounting seat. The positioning plate is provided with a set of assembly holes that are adapted to the straight plate part, and the straight plate part is set on the positioning plate.

[0010] Furthermore, the top of the front and rear derailleur blocks is provided with fitting holes that are compatible with the rotating shaft, and the top end face of the top of the front and rear derailleur blocks is provided with pin holes, and a positioning pin that connects to the rotating shaft is provided in the pin holes.

[0011] Furthermore, the bottom of the front and rear actuating blocks is formed on the side facing the bending plate to create an arc-shaped surface for contact with the cardboard board.

[0012] The beneficial effects of this utility model are as follows: The front left leg of the cardboard box is folded inward to the right by the front actuating block, and the rear left leg is folded inward to the right by the rear actuating block. In conjunction with the bending plate, it ensures that the cardboard box remains in an inward-folded state when entering the inner area of ​​the bending plate. Simultaneously, the guiding action of the bending plate enables the front right leg and rear right leg of the cardboard box to fold inward to the left. Finally, the limiting action of the straight plate ensures that all four legs of the cardboard box are fully folded inward until the inward folding of all four legs is complete. This effectively solves the problems of low automation, high labor costs, high labor intensity, and low box-making efficiency associated with manual inward folding of the four legs of cardboard boxes in existing technologies.

[0013] The actuating cylinder, actuating lever, and rotating shaft work together to achieve reliable rotation of the rotating shaft, while the structure is relatively simple and the cost is low.

[0014] The front and rear actuating blocks are fitted onto the rotating shaft through mounting holes, and their positions on the rotating shaft can be controlled by positioning pins, making the positions of the front and rear actuating blocks relative to the paper box placement area adjustable, which facilitates the adjustment of the positions of the front and rear actuating blocks during operation.

[0015] The curved surface design effectively prevents damage to the cardboard box when it is moved.

[0016] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description
