Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sheet processing, in particular to a fully coated cutting roller knife. Background Art
[0002] During the processing of sheets, according to the process requirements, the sheets need to be die-cut. When the sheets pass through the die-cutting tool holder, the friction coefficient between the sheets and the outer peripheral surfaces of the traditional die-cutting roller and the traditional die-cutting bottom roller is small, and the sheets are prone to sliding friction. The sheets cannot pass through smoothly between the traditional die-cutting roller and the traditional die-cutting bottom roller. Therefore, without power traction, the round die-cutting machine cannot be used to die-cut the sheets. It is necessary to first attach the sheets to the bottom film through the attaching tool holder. Under the traction of the traction tool holder, the bottom film provides power for the forward movement of the sheets, so that the sheets can pass through smoothly between the traditional die-cutting roller and the traditional die-cutting bottom roller on the die-cutting tool holder to complete die-cutting. However, the setting of the bottom film and the cooperation between multiple tool holders not only increase the processing cost of the sheets but also reduce the processing efficiency of the sheets.
[0003] Therefore, a fully coated cutting roller knife that solves the above problems is needed. Content of the Utility Model
[0004] The utility model provides a fully coated cutting roller knife. The setting of two traction rubber sleeves increases the friction between the sheet and the roller body. Cooperating with the die-cutting bottom roller, the roller body has a traction function, providing forward power for the sheet during die-cutting without a bottom film, thereby realizing the traction and die-cutting of single sheets and improving the processing efficiency of the sheets.
[0005] The technical solution of the utility model is realized as follows:
[0006] The fully coated cutting roller knife includes a roller body. Two traction rubber sleeves for pulling the two ends of the sheet are fixedly installed on the outer peripheral surface of the roller body. The two traction rubber sleeves are coaxially arranged with the roller body. At least one fully cutting knife group for die-cutting the sheet is arranged on the outer peripheral surface of the roller body. The fully cutting knife group includes several fully cutting knives arranged at equal intervals. The fully cutting knife group is arranged between the two traction rubber sleeves.
[0007] As a preferred technical solution, each fully cutting knife includes two arc end cutting knives and two straight cutting knives integrally arranged. Both ends of each straight cutting knife are connected to the ends of the corresponding arc end cutting knife.
[0008] As a preferred technical solution, the radius of each fully cutting knife is the same as the radius of the outer peripheral surface of the traction rubber sleeve.
[0009] As a preferred technical solution, an annular groove is provided on the outer peripheral surface of the roller body, the full cutter and the two traction rubber sleeves are both provided in the annular groove, and the outer diameter of the two traction rubber sleeves is the same as the outer diameter of the roller body.
[0010] As a preferred technical solution, the blade of each full cutter gradually becomes smaller from the outside to the inside.
[0011] As a preferred technical solution, the two traction rubber sleeves are symmetrically arranged.
[0012] By adopting the above technical solution, the beneficial effects of the utility model are:
[0013] Since the rubber-coated full-cutting roller knife includes a roller body, two traction rubber sleeves are provided on the roller body. When the roller knife is used in conjunction with the die-cutting bottom roller to die-cut the sheet, the front end of the sheet enters between the rubber-coated full-cutting roller knife and the die-cutting bottom roller, and the two ends of the sheet are pressed by the two traction rubber sleeves and the die-cutting bottom roller. The setting of the two traction rubber sleeves increases the friction between the sheet and the roller body, so that the rubber-coated full-cutting roller knife has a traction function. As the rubber-coated full-cutting roller knife and the die-cutting bottom roller rotate, the sheet is transported downstream. In this process, the middle position of the sheet is die-cut.
[0014] In the present invention, the arrangement of two traction rubber sleeves and a plurality of full-cutting knives enables the rubber-coated full-cutting roller knife to integrate traction and die-cutting functions. The bag body houses the traction knife holder and the die-cutting knife holder, which simplifies the structure of the Band-Aid production equipment. In the absence of a bottom film, it provides forward power for the die-cutting of the sheet, realizes the traction and die-cutting of the sheet, eliminates the laminating process, avoids the coordination between multiple knife holders, and improves the efficiency of sheet processing.
[0015] Since the radius of the outer peripheral surface of the full cutter and the traction rubber sleeve is equal, by setting the annular groove, the top of the full cutter, the outer peripheral surface of the roller body and the outer peripheral surface of the traction sleeve are on the same peripheral surface. When die-cutting the material, the outer peripheral surface of the roller body rests on the outer peripheral surface of the die-cutting bottom roller, avoiding excessive collision between the top of the full cutter and the outer peripheral surface of the die-cutting bottom roller, and reducing damage to the full cutter.
[0016] Since the roller body is provided with a plurality of full cutters, after the sheet die-cutting is completed, the required finished product is located on the inner side of the full cutter, and the outer side of the full cutter is the die-cutting outer frame waste. Compared with the inner side wall vertically arranged in the roller body, the blade of the full cutter in the utility model gradually becomes smaller from the outside to the inside, forming a trumpet shape. As the roller body rotates, the required finished product can be better discharged from the inner side of the full cutter, avoiding the occurrence of the required finished product being stuck in the full cutter and unable to be discharged.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0022] As Figure 1 and Figure 2 collectively shown, the rubber-coated full cut roller knife includes a roller body 1. Two traction rubber sleeves 2 for pulling the two ends of the sheet are fixedly installed on the outer peripheral surface of the roller body 1. The two traction rubber sleeves 2 are coaxially arranged with the roller body 1. At least one full cut knife group for die-cutting the sheet is arranged on the outer peripheral surface of the roller body 1. The full cut knife group includes a plurality of full cut knives 3 arranged at equal intervals. The full cut knife group is arranged between the two traction rubber sleeves 2.
[0023] Among them, each full cut knife 3 includes two arc end cutters 4 and two straight cutters 5 integrally arranged. Both ends of each straight cutter 5 are connected to the ends of the corresponding arc end cutter 4.
[0024] Moreover, the radius of each full cut knife 3 is equal to the radius of the outer peripheral surface of the traction rubber sleeve 2.
[0025] In addition, an annular groove 6 is arranged on the outer peripheral surface of the roller body 1. The full cut knives 3 and the two traction rubber sleeves 2 are both arranged in the annular groove 6. The outer diameters of the two traction rubber sleeves 2 are the same as the outer diameter of the roller body 1.
[0026] Secondly, the cutting edge of each full cut knife 3 gradually becomes smaller from the outside to the inside.
[0027] The two traction rubber sleeves 2 are symmetrically arranged.
[0028] In summary, the arrangement of the two traction rubber sleeves in the present utility model increases the friction between the sheet material and the roller body. Cooperating with the die-cutting bottom roller, the roller body has a traction function. In the case of no bottom film, it provides the driving force for the sheet material during die-cutting, thereby realizing the traction and die-cutting of single sheet materials and improving the efficiency of sheet material processing.
