A cutting device for canvas

Abstract

The invention discloses a cutting device for canvas, which comprises two supports. The top of the support is provided with a top plate, and the middle part of the upper end of the top plate is provided with a cylinder. The piston rod of the cylinder passes through the top plate and the end is provided with a slide rail. The lower end surface of the top plate is provided with a sleeve, the upper end surface of the slide rail 1 is provided with a slide bar slidingly connected with the sleeve, and several slide blocks 1 are equidistantly arranged on the slide rail 1, and the middle part of the support is provided with a connecting rod. A slide rail 2 is fixed on the rod, and a plurality of slide blocks 2 are equidistantly arranged on the slide rail 2. The slide block 1 is arranged above the two adjacent slide block 2 one by one. The front end of the slide block 1 is symmetrically hinged with Connecting rod 1 and connecting rod 2, the connecting rod 1 and connecting rod 2 hinged on the front end of slider 1 are respectively hinged with the two sliders 2 below the slider 1, and the lower end of slider 2 is provided with a cutter. The knives are linked with each other, and the distance between the knives is controlled by the cylinder piston rod. The adjustment method is simple and efficient, and it is suitable for the slitting operation of any width canvas.

[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.
