Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, in particular to a packaging carton folding device. Background Art

[0002] Carton production has a long history and a wide range of applications. With the development of industry and commerce, the demand for packaging continues to increase. Cartons, as a common and important packaging material, have the advantages of relatively low cost, light weight, easy processing and printing, and recyclability. In terms of technological development, early carton production was relatively simple and rough, mainly relying on manual operations. Therefore, the market is in urgent need of a packaging carton folding device.

[0003] However, the prior art still has the following problems:

[0004] Firstly, most of the existing packaging carton folding devices perform extrusion folding on a conveyor belt. However, since most conveyor belts are made of soft materials, the cardboard folding is incomplete, which reduces the overall structural strength of the carton. It is easy to deform and damage during transportation and stacking, and cannot effectively protect the internal items.

[0005] Secondly, most of the existing packaging carton folding devices manually fold the cardboard first and then put it into the device for extrusion. When the cardboard quality is poor, this method is very likely to damage the cardboard due to excessive folding. Utility Model Content

[0010] By adopting the above technical solution, when the lifting plate squeezes the cardboard, it will drive the bottom plate to move downward at the same time, and the bottom plate will drive the two folding plates to move downward. When the folding plates move to the position of the two folding blocks, the cardboard can be folded.

[0011] Preferably, the conveying frame is rotatably connected to the inner walls on both sides of the conveying trough by two conveying rods, and the outer surfaces of the two conveying rods are jointly sleeved with a conveyor belt.

[0012] By adopting the above technical solution, the cardboard can be driven to be conveyed into the cardboard slot through the conveyor belt, and then conveyed to the top of the bottom plate through the cardboard slot, so as to facilitate folding the cardboard.

[0013] Preferably, a pull plate is slidably connected to the inner surface of the lifting plate, and a suction cup is fixedly connected to the bottom end of the pull plate.

[0014] By adopting the above technical solution, the suction cup can absorb the folded cardboard, and then the pull plate can be pulled out to take out the folded cardboard while ensuring the safety of the staff.

[0015] Preferably, a baffle is fixedly connected to one end of the two support plates, a slot is provided at one end of the baffle, and a clamping block used in conjunction with the slot is fixedly connected to one end of the lifting plate.

[0016] By adopting the above technical solution, the lifting plate can be effectively limited so that the lifting plate can perform lifting movements.

[0017] Preferably, both inner walls on both sides of the rectangular groove are fixedly connected with top plates, and the two top plates are distributed in a mirror image.

[0018] By adopting the above technical solution, the telescopic gas rod at the bottom end can be prevented from being damaged due to excessive movement when the lifting plate squeezes the bottom plate.
