Cutting device for canvas

Abstract

The invention discloses a cutting device for canvases. The cutting device for the canvases comprises two supports. A top plate is arranged on the top of the supports, and an air cylinder is arranged in the middle of the upper end of the top plate; the piston rod of the air cylinder penetrates through the top plate, and the tail end of the piston rod of the air cylinder is provided with a first sliding rail; a sleeve is arranged on the lower end face of the top plate, and a sliding rod which is in sliding connection with the sleeve is arranged on the upper end face of the first sliding rail; aplurality of first sliding blocks are arranged on the first sliding rail at equal intervals, and a connecting rod is arranged in the middles of the supports; a second sliding rail is fixed on the connecting rod, and a plurality of second sliding blocks are arranged on the second sliding sliding rail at equal intervals; the first sliding blocks are arranged above the two adjacent second sliding blocks one by one; the front end face of each first sliding block is symmetrically hinged to a first connecting rod and a second connecting rod; and the first connecting rod and the second connecting rodhinged to the front end surface of each first sliding block are respectively hinged to the two second sliding blocks below the first sliding block; a cutter is arranged at the lower end of each second sliding block, and the cutters are linked to one another by the device. The distance between the cutters is controlled through the piston rod of the air cylinder, an adjusting method is simple and efficient, and the cutting device is suitable for cutting canvases in optional widths.

Description

technical field [0001] The invention belongs to the technical field of canvas cutting, and in particular relates to a cutting device for canvas. Background technique [0002] Canvas refers to a kind of heavy fabric, which is used for oil painting or acrylic painting. The surface of the canvas is painted with a white base layer for painters to use. In the production process of canvas, it is usually necessary to cut the larger canvas into several smaller ones. canvas to meet the needs of users, but because the size of the canvas required by the user is different when drawing, the manufacturer needs to cut out canvases of different sizes. The existing slitting equipment often needs to adjust the cutter when slitting. The relative position is adapted to the slitting of canvases of different widths.

[0002] Canvas refers to a kind of heavy fabric, which is used for oil painting or acrylic painting. The surface of the canvas is painted with a white base layer for painters to use. In the production process of canvas, it is usually necessary to cut the larger canvas into several smaller ones. canvas to meet the needs of users, but because the size of the canvas required by the user is different when drawing, the manufacturer needs to cut out canvases of different sizes. The existing slitting equipment often needs to adjust the cutter when slitting. The relative position is adapted to the slitting of canvases of different widths. Since the knives are not related to each other, it is necessary to measure and adjust the positions of all knives when changing the slitting width. The adjustment process is cumbersome. It is prone to the phenomenon that the canvas is not cut smoothly. It is necessary to move the cutter to a position close to the canvas to increase the pressure on the canvas to ensure the cutting effect. Obviously, the adjustment process is time-consuming and laborious.
