Abstract

The invention discloses a rag knife which comprises a pair of rag cutting blades, a rolling shaft I and a rolling shaft II. Two ends of the rolling shaft I are connected with a support and the rolling shaft II is fixedly arranged on the support through fixing bases; the rolling shaft II is arranged below the rolling shaft I in parallel with the rolling shaft I; the rag cutting blades are arranged on the rolling shaft I; the rolling shaft II is matched with a rag under cutting; the rolling shaft I is connected with the support through sliding bases; the rag knife further comprises a pair of cylinders which are respectively arranged on the upsides of the two sides of the support; adjusting nuts are arranged at the top ends of piston rods of the cylinders, and the bottom ends of the piston rods are fixedly connected with the sliding base of the rolling shaft I; an air inlet and an air outlet, which are connected with an air pipe, are arranged on the barrel of each cylinder; and the other end of the air pipe is connected with an air storage device. The rag knife is simple in structure and convenient to install; the acting force and the gap between the rag cutting blades and the rolling shaft II are controlled according to the thickness of the cut rag, so the rate of malfunction or breakage of the rag cutting blades is reduced, and the problems of low production efficiency and production safety caused by breakage of the blades are solved.

Description

Rag knife

Technical field

The invention belongs to the device for the textile package rolling, be specifically related to the rag knife that uses in a kind of cloth postorder winding process.

Background technology

In the postorder winding process of Woven Fabrics and other clothes, in order to meet customer need, need the edge cuts of cloth is neat.The cloth cutter sweep that uses at present is provided with up and down two roller bearings and a pair of rag knife sheet, circular rag knife sheet is nested with on upper roller bearing, rag knife sheet on the driven by motor roller bearing rotates, lower roller bearing cooperates with cloth, cloth passes through from lower roller bearing, drive lower roller bearing by the frictional force cloth and rotate, realize rotating synchronously by two roller bearings about the gear drive, the rag knife sheet cuts cloth simultaneously.But there is a lot of defectives:

When 1, cloth was thick and heavy, blade was easy to rust, and the rag knife sheet is inoperative; When 2, cloth was too thin, blade and the direct friction of lower roller bearing caused blade fracture or rust easily, caused production line to pause in this link easily when continuous productive process, and the production efficiency of production line is reduced.

Summary of the invention

The problems referred to above that exist in order to overcome the prior art field the object of the invention is to, and a kind of rag knife is provided, and the blade that solves existing rag knife is subjected to the impact of fabric thickness, is prone to fracture or rust phenomenon, the problem that production efficiency is reduced.

Rag knife provided by the invention, it comprises a pair of rag knife sheet, roller bearing I, roller bearing II, described roller bearing I two ends are connected with support, roller bearing II is fixed on the support by fixed pedestal, roller bearing II is set in parallel in below the roller bearing I, a pair of rag knife sheet is arranged on the roller bearing I, roller bearing II is cut cloth with quilt and is cooperated, described roller bearing I is connected with support by glide base, rag knife also comprises a pair of cylinder, described a pair of cylinder be separately positioned on the support both sides above, the top of cylinder piston rod is provided with adjusting nut, the piston rod bottom is fixedly connected with the glide base of roller bearing I, and the cylinder barrel of cylinder is provided with the air admission hole that is connected with tracheae, air outlet, the other end of tracheae is connected with the gaseous storage device.It also comprises bearing, and described bearing is arranged on the two ends of roller bearing I, roller bearing I I, cooperates with glide base, fixed pedestal respectively.It also comprises slideway, and described slideway is the slideway of the glide base side that is connected with support of roller bearing I, and the inwall of support both sides is provided with the slide block that cooperates with the glide base slideway.It also comprises gas valve, and described gas valve is connected with the gaseous storage device.

Rag knife provided by the invention, its beneficial effect is, this cutter structure is simple, easy for installation, according to active force and the gap between the THICKNESS CONTROL rag knife sheet of being cut cloth and roller bearing II, reduced the probability of cutting motionless or breaks down that the rag knife sheet exists, the production efficiency that causes easily when avoiding blade breakages reduces and the production safety problem.

The specific embodiment

With reference to the accompanying drawings, in conjunction with the embodiments, to rag knife provided by the invention, be described in detail.

Embodiment

With reference to Fig. 1-Fig. 2, the rag knife of present embodiment, it comprises a pair of rag knife sheet 13, roller bearing I 1, roller bearing II 2, described roller bearing I 1 two ends are connected with support 3, roller bearing II 2 is fixed on the support 3 by fixed pedestal 11, roller bearing II 2 is set in parallel in below the roller bearing I 1,13 of a pair of rag knifes are arranged on the roller bearing I1, roller bearing II 2 is cut cloth with quilt and is cooperated, described roller bearing I 1 is connected with support 3 by glide base 10, rag knife also comprises a pair of cylinder 4, described a pair of cylinder 4 be separately positioned on support 3 both sides above, the top of cylinder piston rod 5 is provided with adjusting nut 6, piston rod 5 bottoms are fixedly connected with the glide base 10 of roller bearing I1, the cylinder barrel of cylinder 4 is provided with the air admission hole 7 that is connected with tracheae, air outlet 8, the other end of tracheae is connected with the gaseous storage device.It also comprises bearing, and described bearing is arranged on the two ends of roller bearing I 1, roller bearing II 2, cooperates with glide base 10, fixed pedestal 11 respectively.It also comprises slideway 9, and described slideway 9 is the slideway 9 of glide base 10 sides that are connected with support 3 of roller bearing I 1, and the inwall of support 3 both sides is provided with the slide block 12 that cooperates with glide base 10 slideways 9.It also comprises gas valve, and described gas valve is connected with the gaseous storage device.

Before the work, needs according to actual production, the adjusting nut 6 on regulating piston bar 5 tops, to be cut the cloth traction on roller bearing II2, open simultaneously the gas valve that is connected with the gaseous storage device, the pressure of adjusting cylinders 4, the gaseous storage device is by the air admission hole 7 of tracheae and cylinder 4, air outlet 8 connects, gas enters cylinder 4 from air admission hole 7, rag knife sheet 13 on the roller bearing I 1 drops on the cloth, during cloth process roller bearing II2, drives roller bearing II 2 and rotates, frictional force by cloth and roller bearing I 1 and roller bearing II 2 makes two roller bearing backward rotation, has finished simultaneously the cutting work of 13 pairs of clothes of rag knife sheet.After cutting work was finished, the gas in the cylinder 4 was got rid of from air outlet 8, and roller bearing I 1 lifts, and returns to initial position, in order to using next time.This cutter structure is simple, easy for installation, active force and gap according to 2 of the THICKNESS CONTROL rag knife sheet of being cut cloth and roller bearing II, reduced the probability of cutting motionless or breaks down that the rag knife sheet exists, the production efficiency that causes easily when avoiding blade breakages reduces and the production safety problem.
