Description

Shearing equipment of high compliance crepe paper

Technical Field

The utility model relates to a paper shearing equipment especially relates to a shearing equipment of high compliance crepe paper.

Background

The prior paper shearing equipment is often applied to paper in a stacked state or paper with hard paper, and the paper has considerable structural strength at the moment, so that acting force generated by the paper on a blade can be kept in a flat state, so that the blade applies enough pressure to the paper to cut off fibrous tissues of the paper, for example, a semi-automatic paper shearing device disclosed in Chinese patent literature, the publication No. CN106826955B comprises a rectangular base, a rectangular box body is fixedly connected to the upper surface of the rectangular base, a rectangular frame is fixedly connected to the rear surface of the rectangular base, a pair of first circular grooves corresponding in position are processed on the upper surface of the rectangular frame, an upright post is fixedly connected in each first circular groove, a first rectangular block is fixedly connected to the upper end of the side surface of each upright post, and a second circular groove is processed on the side surface of one of the first rectangular blocks, a first rotating shaft is movably connected in the second circular groove, and a first circular gasket is fixedly connected to one end of the first rotating shaft. When the paper is softer, or when being in the sola state, the intensity of the fibrous tissue perpendicular to paper direction of its paper is often not enough for when the cutter is sheared the paper, the paper easily takes place the buckling of the pressure direction that the cutter exerted, and because the plate that provides the support to the paper corresponds the position and is equipped with the groove of dodging that is used for falling the sword, leads to the plate can't avoid the buckling of here paper, finally leads to the cutter can't produce sufficient pressure to the paper surface, thereby shears the failure.

SUMMERY OF THE UTILITY MODEL

The utility model relates to an overcome the problem that current paper shearing mechanism can't cut comparatively soft paper or sola paper, provide a shearing equipment of high compliance crepe paper, can cut comparatively soft paper.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a shearing equipment of high compliance crepe paper, is including shearing cutter unit, knife rest and actuating mechanism, it includes the cutter body and is used for the exhibition to be cut the briquetting subassembly of paper to cut the cutter unit, the knife rest is including being used for providing the bed frame of impetus for drive arrangement, being used for the fastening frame of fixed cutter body and being used for placing the cutting plate of being cut the paper, the cutting plate is equipped with and dodges the groove, drive arrangement's stiff end and bed frame fixed connection, drive arrangement's power take off end and fastening frame fixed connection, the briquetting subassembly includes first briquetting and second briquetting, first briquetting and second briquetting are located the cutter body both sides respectively, rotate through the pivot respectively between with the fastening frame and are connected, pivot department is equipped with the first spring that is used for reseing, and the cross-section of first briquetting and second briquetting is oval. When the paper is too soft, or is in the sola state, its intensity perpendicular to paper direction often is not enough for when the cutter is sheared the paper, the paper easily takes place the buckling of cutter applied pressure direction, and because the cutting plate corresponding position that provides the support to the paper is equipped with the groove of dodging that is used for the falling knife, leads to the cutting plate can't avoid the buckling of here paper, finally leads to the cutter can't produce sufficient pressure to the paper surface, thereby the shearing fails. The press block assembly is matched with the cutter body, when the cutter body falls along with the fastening frame, the press block assembly is positioned on two sides of the cutter body, and presses and stretches the cut paper to two sides of the cutter body, so that the cutting point of the paper can be kept flat under the acting force of the cutter body, and the cutter body can generate enough pressure on the paper to cut the paper.

Preferably, the fastening frame is provided with a sliding mechanism at a position corresponding to the fastening frame, the sliding mechanism comprises a sliding rail located on the fastening frame and a sliding block matched with the sliding rail to slide, the sliding block is rotatably connected with the first pressing block and the second pressing block through a rotating shaft, and a second spring is arranged between the sliding block and the sliding rail. The effect of slide mechanism is for the briquetting subassembly provides the pressure of reservation, because the briquetting subassembly comes from the pressure of fastener with the tensile effort of paper, consequently when the pressure of fastener is too big, can cause the tensile too much and fracture of paper, through the effort that second spring transmission drive arrangement produced between the slider in the slide mechanism and the slide rail for through the cushioning effect of second spring, the fastener can reduce the accuracy of pressure numerical value, thereby avoid causing the rejection rate of paper shearing process to rise because slight pressure difference value.

Preferably, an included angle is formed between one side of the cutting edge of the cutter body and the horizontal plane. The existence of contained angle makes when the cutter body descends along with the fastener, and the cutting edge of one side contacts the paper at first, and at the in-process that the cutter body descends, the shear line of paper contacts with the cutting edge in proper order to improve the pressure of shearing department, optimize the shearing effect.

Preferably, the cutter body is connected with the fastening frame through bolts. The cutter body is convenient to replace.

Preferably, a rubber brush is arranged in the avoiding groove. The rubber brush is used for removing residual paper scraps on the cutter body.

Preferably, the first pressing block and the second pressing block are respectively provided with a rubber belt and a plurality of rollers for supporting the rubber belt. The rubber tape cover is established outside the ring face of first briquetting and second briquetting, rotates between support and first briquetting, the second briquetting through the gyro wheel and is connected, and the effect of rubber sleeve is when making first briquetting, second briquetting take place to rotate, is in rotational friction between the contact point of its and paper to avoid first briquetting or second briquetting fish tail paper.

Preferably, the driving means is a cylinder.

Therefore, the utility model discloses following beneficial effect has: (1) the press block assembly is matched with the cutter body, when the cutter body falls along with the fastening frame, the press block assembly is positioned on two sides of the cutter body, and presses and stretches the cut paper to two sides of the cutter body, so that the cutting point of the paper can be kept flat under the acting force of the cutter body, and the cutter body can generate enough pressure on the paper to cut the paper; (2) the sliding mechanism is used for providing preset pressure for the briquetting assembly and avoiding the paper from being broken due to excessive stretching of the paper caused by excessive pressure of the fastening piece.
