Negative pressure principle based flat setting device for canvas production

Abstract

The invention relates to the technical field of canvas production, and discloses a negative pressure principle based flat setting device for canvas production. The device comprises an operation platform, a shell is arranged above the operation platform, an adsorption plate is fixedly installed at the upper end inside the shell, a negative pressure shell is fixedly installed on the upper surface ofthe shell, and a hydraulic rod is fixedly installed at the upper end of the negative pressure shell. Through the cooperative use of a seal plate, a negative pressure suction head, a heating block, afinishing ball and an atomization pipe, water in the shell can be atomized out, and the atomized water is sprayed on a canvas, so that fiber tissues are expanded, loose and stretched when the heatingblock and the finishing ball are used for finishing wrinkles on the canvas; by virtue of the lubricating effect of water molecules, fiber internal macromolecules are easy to move, hot compression molding is facilitated, and finally the purpose of heat setting is achieved; and the use is facilitated, the canvas is not cancelled, and the environment and resources are protected.

Description

technical field [0001] The invention relates to the technical field of canvas production, in particular to a flattening and shaping device for canvas production based on the principle of negative pressure. Background technique [0002] Canvas is a thick and strong plain weave cloth of different weights woven from hemp or cotton yarn, used to make tents, camp beds, clothes, shoes, etc. Canvas has good waterproof performance and is used for covering automobiles and open warehouses and setting up tents in the wild , fine canvas is used to make labor protection clothing and its supplies, and can also be used as fabrics for shoes, travel bags, backpacks, etc. after dyeing. [0003] At present, in the production process of the existing canvas production equipment, because the fiber itself is elastic, the uneven horizontal force will cause the material to deform, and the fiber rebound is not so fast and not so good, so it is easy to form wrinkles. If some The fiber resilience is r...

Problems solved by technology

[0003] At present, in the production process of the existing canvas production equipment, because the fiber itself is elastic, the uneven horizontal force will cause the material to deform, and the fiber rebound is not so fast and not so good, so it is easy to form wrinkles. If some The fiber resilience is relatively poor, and wrinkles will also appear, which will affect the reprocessing of the canvas. During the dyeing process, if there are wrinkles, the folded parts may not be dyed, and eventually the entire piece of canvas will be scrapped and wasted. Wasted manpower and resources, waste cloth cannot be degraded in time, and pollute the environment
