Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bandage processing, in particular to a rubber-coated full-cut traction device. Background Art
[0002] In the processing of Band-Aids, it is common to use coils as raw materials. According to process requirements, it is now necessary to use sheets as raw materials for the processing of Band-Aids. The existing method is to first stick the sheet on a backing film, and then the sheet passes through a flat-knife die-cutting machine under the traction of the backing film. When the flat-knife die-cutting machine is die-cutting the sheet, the material belt stops moving. After the sheet at the die-cutting position is die-cut, the backing film pulls the sheet to move, and the sheet to be die-cut is moved to the die-cutting position for die-cutting. This process is repeated until all the sheets on the backing film are die-cut. During this process, the backing film moves intermittently, and the sheet cannot be die-cut continuously, which makes the production efficiency of Band-Aids low.
[0003] Therefore, a rubberized full-cut traction device is needed to solve the above problems. Utility Model Content
[0004] The utility model provides a rubber-coated full-cutting traction device, which eliminates the process of compounding sheets and base films. Only one knife seat is used to achieve traction and continuous die-cutting of multiple sheets, thereby improving the production efficiency of bandages.
[0005] The technical solution of the present utility model is achieved as follows:
[0006] The rubber-coated full-cutting traction device includes a knife seat, on which a rubber-coated traction die-cutting roller and a die-cutting bottom roller for cooperating in traction and die-cutting of the sheet are rotatably mounted. Two traction rubber sleeves are fixedly mounted on the outer circumference of the rubber-coated traction die-cutting roller. At least one full-cutter group is provided on the outer circumference of the rubber-coated traction die-cutting roller. The full-cutter group includes a plurality of full-cutters arranged at equal intervals. The full-cutter group is arranged between the two traction rubber sleeves. A transmission bottom roller is provided below the die-cutting bottom roller. The transmission bottom roller, the rubber-coated traction die-cutting roller and the die-cutting bottom roller are sequentially connected in transmission from bottom to top.
[0007] As a preferred technical solution, an annular groove is provided on the outer peripheral surface of the rubber-coated traction die-cutting roller, and the full cutter and the two traction rubber sleeves are both arranged in the annular groove. The radii of the outer peripheral surface of the rubber-coated traction die-cutting roller, the outer peripheral surfaces of the two traction rubber sleeves and the full cutter are all equal.
[0008] As a preferred technical solution, each of the full cutters includes two arc-shaped end cutters and two straight line cutters that are integrally arranged, and both ends of each straight line cutter are connected to the end of the corresponding arc-shaped end cutter.
[0009] As a preferred technical solution, the blade of each full cutter gradually becomes smaller from the inside to the outside.
[0010] As a preferred technical solution, the two traction rubber sleeves are symmetrically arranged.
[0011] By adopting the above technical solution, the beneficial effects of the utility model are:
[0012] Since the rubber-coated full-cut traction device includes a rubber-coated traction die-cutting roller, during the use of this device, the sheet is conveyed to the knife holder through the conveying mechanism, and the two ends of the sheet are pressed by the cooperation of the two traction rubber sleeves and the die-cutting bottom roller. As the rubber-coated traction die-cutting roller and the die-cutting bottom roller rotate, the sheet passes through between the rubber-coated traction die-cutting roller and the die-cutting bottom roller to achieve traction of the sheet. In the process of the rubber-coated traction die-cutting roller and the die-cutting bottom roller rolling the sheet, the full-cutting knife on the rubber-coated traction die-cutting roller penetrates the sheet to achieve full cutting of the sheet. In the utility model, only one knife holder is required, and in the absence of bottom film traction, continuous die-cutting of a single sheet is achieved through the cooperation of the rubber-coated traction die-cutting roller and the die-cutting bottom roller, thereby improving the production efficiency of Band-Aids.
[0013] Since the rubber-coated full-cutting traction device includes a rubber-coated traction die-cutting roller, during the production process of the Band-Aid, the traction rubber sleeve is softer than the outer peripheral surface of the rubber-coated traction die-cutting roller, and is squeezed by the outer peripheral surface of the die-cutting bottom roller and deformed, which will cause the full cutter to collide with the outer peripheral surface of the die-cutting bottom roller, causing damage to the full cutter. In the present invention, the radii of the outer peripheral surface of the rubber-coated traction die-cutting roller, the outer peripheral surfaces of the two traction rubber sleeves and the full cutter are all equal. When the traction rubber sleeve is deformed, the outer peripheral surface of the rubber-coated traction die-cutting roller rests on the outer peripheral surface of the die-cutting bottom roller, thereby avoiding the collision of the full cutter with the die-cutting bottom roller and improving the service life of the full cutter.
[0014] Since the blade of each full cutter gradually becomes smaller from the inside to the outside, the full cutter is trumpet-shaped, which is conducive to the required finished product being discharged from the inside of the full cutter after the sheet die-cutting is completed.
