Fiber cutter, also known as glass fiber cutting machine, aramid fiber cutting machine, chemical fiber fiber cutting machine, etc., is a different type of application according to different uses. It is a universal cutting device with a wide range of applications. A variety of different types of raw materials are cut according to different requirements to meet people's demand for materials. It is divided into a rotary hob type fiber cutter, Sickle fiber cutter, parallel blade fiber cutter, and the like.

Along with the continuous advancement of human science and technology, various new and high-tech production materials have emerged in various application fields, and new products are not only qualified products, but also a large number of non-conforming products and waste products. Waste products are similar in cost to the raw materials of the root quality products, so it is impossible to discard them and cannot process them for reuse. 

Most of the textile fiber products are characterized by low hardness, but the fiber structure is closely intertwined, the pulling force is large, and the shape is not fixed. It is very difficult to break the material and cut it.

Types and characteristics 

Rotary hob fiber cutting machine 

The rotary hob type adopts the continuous rotation of the drum type cutterhead. According to the inclination of a certain position and direction, the direction of the blade edge is the direction of rotation of the rotary cutter disc, and the one-piece fixed straight blade is used. The cooperation between the two cutters is very The compact fit, continuously rotating multi-piece rotary cutter, automatically presses and cuts the raw material sent from the feeding system, and then automatically conveys the shearing system through the conveyor belt. 

In the material feeding system, it adopts a parallel and uniform conveying belt of different lengths and lengths. There are two pairs of relatively rotating self-sliding pressure regulating pressure rollers at the front end of the cutting edge to clamp the material. In normal production, the material can be conveniently placed. Continuously placed on the conveyor belt, automatically fed into the pressing device and the cutting tool to complete the cutting. After cutting, the material falls into the output belt in the direction of the outlet and is sent out.

Features: 

(1) The cutter disc of the fiber cutting machine can be installed with 1 to 10 rotating cutters, and the length of the knife edge is 400-800 mm; 

(2) The thickness of the shearing material can reach 1-100mm; 

(3) The cutting length is between 5 and 150 mm; 

(4) high cutting efficiency and high length accuracy; 

(5) The cutting times are up to 2000 times per minute, which can be applied to all kinds of waste cloth trimmings, old clothes, cotton wool, chemical fiber, glass fiber, linen, textile silk, leather, carton, plastic film, etc. Non-directional soft material is cut and chopped. 

(6) If the traveling speed of the conveying device is arbitrarily changed while the rotational speed of the shearing cutter is constant, the length and size of the material to be sheared are changed, which is more suitable for a large number of different specifications. And cut off the required work needs.

Sickle fiber cutting machine

The boring cutter is a blade that linearly moves in a pair of vertical plane directions. The feed guide roller of the synchronous feeding device feeds the cut tow into the cutting port, and the cutting length required for fixing the stopper is used to complete the cutting jobs.
Features: 

(1) The structure of the device is simple, and the adjustment range of the cutting length is wide (the shortest is even 0.1mm); 

(2) The requirements for the cut tow are not high, and it is possible to process materials of various specifications, even various types of corners. 

(3) The cutting efficiency is low, and the accuracy of the cutting length is poor; Due to the simple structure and low price of the cutting machine, at present, many domestic engineering fiber manufacturers mostly use such cutting equipment.

Parallel blade fiber cutting machine

That is, the cutting edge of the cutting blade on the cutter head is arranged in a plane direction with the cutting edge facing upward, and the distance between the cutting edges is the required cutting length. The inclined tow is used to feed the tow into the cutter head. The cutter head is rotated and the tow is cut into the required cut length.

Features: 

(1) After the fiber is cut, it falls vertically in a free state, and the cotton is relatively smooth; 

(2) Adopting the pressure wheel to drive the tow feed, the cutting precision is high; 

(3) The pressure roller is in contact with a plurality of blades at the same time to form a cut, and the cutting efficiency is high; 

(4) The equipment structure is complex and the maintenance requirements are high; 

(5) There is a difference between the outer edge of the cutting edge and the inner length, so that the actual working length of the blade has to be reduced, which affects its cutting ability.

Radial fiber cutting machine

That is, all the blades on the cutter head are vertically arranged along the circumference, and the cutting edges are outwardly arranged in a radial arrangement, and the distance between the cutting edges of the blades is the required cutting length. The cutter head rotates to feed the tow, and the parallel pressure roller contacts the blade edge to cut off. 

Features: 

(1) The cutting edges of the blades are parallel to each other, and there is no difference in the cutting length, and the cutting precision is high; 

(2) The blade has a large working length and a high cutting capacity; 

(3) The cutter head is simple in design and easy to maintain, and can be suitable for various cutting requirements; 

(4) The number of blades required for the cutterhead at the same scale is small.

Select 

The selection of the fiber cutting machine is basically selected according to the shape, pattern, length and output of the raw materials. Since the shearing requirements for different raw materials are different in production and life, people choose according to their own work requirements, and the new aviation fiber cutting machine As an example of a rotary hob cutter, it uses an automatic conveyor belt to convey material, and a double-stage pressure roller pressing device at the front end of the knife edge, with a protective cover, which can prevent the cutting edge width from 400-800 mm. Material thickness 30-80mm, can cut the length of any adjustment between 5-300mm, the output per hour is about 300-1500kg, can be applied to all kinds of waste cloth edge materials, old clothing, cotton fiber, fiberglass, linen, back Silk leather, carton, plastic film and other irregular, non-directional soft material shearing, because the rotating knife uses multiple pieces, which reduces the cost of blade wear and replacement, and ensures the reliability of a large number of material shearing.
