Description

Technical Field

[0001] The utility model relates to the textile field, in particular to a carton opening mechanism. Background Art

[0002] In the existing textile industry, weaving mills basically manually remove cartons filled with spindles from the pallet pallets on the ground, and then manually cut and slash all the packing ties and sealing tapes on the cartons with blades, and then manually pull the bent paper pages (4 pages on each side) of the carton upward and outward, and then manually take out all the spindles in the box and put them on another pallet or container next to it. This is very labor-intensive and the efficiency will become lower and lower over time, which requires a lot of labor. In addition, since the unpacking knives are very sharp, it is easy to cut the spindles in the box during the manual unpacking process, resulting in the scrapping of the entire roll of spindles; it is also easy to damage the box, resulting in the box cannot be recycled intact, and finally can only be treated as waste paper, resulting in a large waste of resources. Summary of the invention

[0003] In order to solve the above problems, the utility model proposes a carton opening mechanism to achieve the purpose of using a mechanical device to replace manual opening of the carton.

[0004] A carton opening mechanism, the opening mechanism comprising a carton opening knife; the opening mechanism also comprising a barb;

[0005] Two opening mechanisms are arranged in a group on both sides of the carton. When opening the carton, the box opening knives of the two opening mechanisms move toward each other along the seam between the two outer cardboards on the top or bottom of the carton and cut the sealing tape connecting the two outer cardboards on the top or bottom of the carton, and the barbs of the two opening mechanisms move toward each other along the seam between the two outer cardboards on the top or bottom of the carton and buckle the two inner cardboards on the top or bottom of the carton through the seam between the two outer cardboards on the top or bottom of the carton, and the barbs of the two opening mechanisms swing up to open the two inner cardboards and the two outer cardboards on the top or bottom of the carton.

[0006] The box cutter and the barb are installed on a swing arm, with the box cutter at the front and the barb at the back. The swing arm is hinged on a slide, and the slide is installed on a bracket. The swing arm is connected to a driving structure A installed on the slide, and is driven by the driving structure A to swing up and down. The slide is connected to a driving structure B installed on the bracket, and is driven to move by the driving structure B. The box cutter and the barb move with the slide, and the barb swings up and down with the swing arm. Preferably, the driving structure A is a cylinder; and the driving structure B is composed of a motor connected with a synchronous belt and a pulley.

[0007] The box cutter comprises a vertical blade, which is fixedly connected to the front end of the swing arm and forms a vertical cutting edge below the swing arm.

[0008] The box cutter also includes a transverse blade, which is also fixedly connected to the front end of the swing arm to form a transverse cutting edge below the swing arm. The vertical cutting edge and the transverse cutting edge together form an inverted "T"-shaped cutting edge.

[0009] The box cutter is an electric circular saw.

[0010] The opening mechanism also includes a front box-opening knife, and the front box-opening knife is fixedly connected to the bracket;

[0011] When the carton enters the two opening mechanisms, the carton moves, and the front box-opening knife moves relative to the carton to cut the sealing tape on the side of the carton.

[0012] The front box cutter is a transverse blade.

[0013] The barb is hinged at the middle position of the swing arm, a guide block is installed on the swing arm, a guide rod is arranged inside the guide block, the guide rod is slidably connected with the guide block, one end of the guide rod extends out, a hinge head is installed on the guide rod, and the guide rod is hinged with the barb through the hinge head, a spring is sleeved on the guide rod, and the two ends of the spring are respectively against the guide block and the hinge head, and a support plate is installed on the bracket; the support plate extends to the upper side or the lower side of the carton;

[0014] The barb is pressed against the supporting plate, moves with the sliding plate, breaks away from the restriction of the supporting plate, and extends out under the action of the spring.

[0015] A connecting rod is hinged on the slide plate, the connecting rod is located above the swing arm, and the guide block is fixedly connected to the connecting rod; with this design, the guide block can adapt to the position change of the guide column, so that the barb can be smoothly extended and retracted. When the swing arm swings upward, the connecting rod forms a triangle with it, driving the guide block to move relative to the barb, applying elastic force to the barb, so that it is fastened and not easy to loosen.

[0016] There are two groups of opening mechanisms, one above and one below, so that the top and bottom of the carton are opened at the same time; the opening mechanisms located on the same side of the carton share a bracket.

[0017] The utility model has the advantages of reasonable design and simple structure. The carton is opened by using a box opening knife in cooperation with a barb, replacing the traditional manual box opening. The carton opening effect is high and accurate, and the carton and the spindles in the carton are not damaged. BRIEF DESCRIPTION OF THE DRAWINGS
