Description

A kind of carton forming method

technical field

The invention relates to the field of carton packaging, in particular to a carton forming method.

Background technique

In recent years, with the continuous improvement of living standards, people's purchasing power has been greatly enhanced, which has brought unlimited business opportunities for e-commerce that can provide convenient services and high-quality and low-cost commodities. However, in the initial stage of online store operation, small online stores often face the problem of a small number of workers and a heavy workload. For online stores, the packaging of goods has become the node with the largest workload in each order.

The outer packaging of the product is mainly to meet the needs of safety and portability when the product is transported by express delivery. It is mainly divided into carton packaging and paper bag packaging. The workload of carton packaging is greater than that of paper bag packaging, which requires carton forming and carton packaging. Series of work, manual operation is labor-intensive. However, the existing carton packaging machines are mainly for assembly-line operations, occupy a large area overall, and have high costs. Most of them are purchased by medium and large enterprises, and they are poorly popularized for small shops.

Patent No. CN201520891248.1 discloses a new carton packaging machine for articles, which includes a frame, a carton transfer device, an active case closing device, and a box surface sealing device. The carton transfer device includes a screw rod set on the frame , the screw connecting seat configured with the screw thread, the carton clamping mechanism connected with the screw connecting seat, the active box closing device is arranged above the carton conveying device, and the active box closing device includes a The front box closing baffle, the rear box closing pole, the telescopic left lever and the telescopic right lever symmetrically arranged on both sides of the linkage bracket, the box surface sealing device is arranged above the carton conveyor, and the The box surface sealing device includes a sealing machine and a lifting mechanism for controlling the lifting of the sealing machine.

Among them, the main steps of carton forming are completed by the active closing device. The active closing device includes a front closing baffle fixed at one end of the frame, a rear closing pole arranged at the other end of the frame, and symmetrically arranged on the linkage. The telescopic left lever and the telescopic right lever on both sides of the bracket, wherein, the rear edge closing pole is arranged on the linkage bracket, and three guide rod guide rails are symmetrically arranged on both sides of the frame, and the linkage bracket The support rods on both sides are respectively set by sliding with the guide rails of the three guide rods. The structure of the telescopic left driving rod and the telescopic right driving rod are the same, and they are both hinged cross guide rods. The telescopic left driving rod and the telescopic The ends of the right driving rod are all slidably set with the guide rails of the three guide rods, and are stretched and contracted by the promotion of the linkage bracket. When it is necessary to close the cartons, during the movement of the linkage bracket, the rear edge closing rod moves forward to perform the rear edge closing action, and the cartons move forward for a small displacement, which is pushed by the front closing baffle The front edge of the carton completes the closing action of the front edge. After the closing action of the front and rear edges is completed, the cross guide rod is pushed by the linkage bracket, and the double rods are closed along the predetermined track, and the left and right edges of the carton are pushed forward to perform the closing action and end the carton closing process. .

Among them, because the guide rod directly pushes the edge of the carton to perform bending action, the outer surface of the carton will be worn due to the large friction force; in addition, the carton is transported by the carton clamping mechanism after the carton is clamped, and then through the screw rod. Drive it to move, because it is driven by a screw, so the speed is very slow, the efficiency is too low, and it is difficult to realize continuous production.
