Detailed Description
The core of the invention is to provide a high-speed Gao Chandao f metal card clothing.
The invention is further described below with reference to the accompanying drawings:
The high-speed Gao Chandao-f metal card clothing comprises a base 1 and three main comb teeth 2 protruding from the base 1, wherein the main comb teeth 2 comprise front teeth of a working surface and back teeth of a transferring surface; the front teeth are of sickle structures and comprise tooth tips 3, tooth edges and small corners 4, the end faces of the tooth tips are parallel to the base 1, the horizontal direction of the small corners 4 and the base 1 form a horizontal working surface horizontally, and the vertical direction is an arc line and is connected with the tooth edges; four raised triangular prism teeth 5 are arranged on the back teeth, the back gear profile is divided into a first back tooth line and a second back tooth line, the triangular prism teeth 5 are triangular prism teeth with isosceles right triangles on the bottom surface, and the bottom surface is consistent with the back tooth profile in direction; the back tooth profile line is an arc line, the first back tooth line is connected with the horizontal working surface of the front tooth tip 3, and the second back tooth line is connected with the front teeth of the adjacent main comb teeth 2 in a smooth manner by adopting an arc line; the small corners 4 divide the front tooth profile into a first front tooth profile and a second front tooth profile; the first front tooth trace is connected with the tooth tip 3 and the small corner 4, and the second front tooth trace is connected with the second back tooth trace in a smooth way through an arc after being in a straight line with the base 1; the back teeth and the front teeth of two adjacent main comb teeth 2 form a funnel-shaped tooth gap 6 with a large opening and a small bottom; the height difference range of the triangular prism teeth 5 is 0.10-0.20 mm, the tooth height range of the front teeth is 0.50-1.00 mm, and the width of the tooth parallel base 1 of the front teeth is 0.30-0.55 mm.
When the comb is particularly used, the front upper working face is arranged on the working side of the original comb teeth in a protruding mode, four triangular ribs are added on the tooth backs, so that a tooth root sickle tooth structure is formed, in the process of transferring held fibers, the triangular ribs on the tooth backs hold the injected fibers, the fibers are held and taken away in the sickle area of the front working face of the main comb teeth 2, the holding and transferring effect of the comb teeth is improved, meanwhile, the fibers are controlled and released in a supporting mode through the aid of a funnel formed by the tooth working face and the tooth backs, the tooth depth of the metal card clothing is increased by more than 30% through the increase of the working depth of the upper sickle-shaped needle points, and the transferring fiber quantity is increased. In addition, the addition of the triangular ribs of the sickle tooth structure eliminates the falling net of the fiber during high-speed and high-yield operation, and the strip outlet can be lifted from 80-90m/min to 180-200m/min.
Example 1:
Three main comb teeth 2 are arranged along the strip-shaped base 1 in a protruding mode, a concave platform which is parallel to the base 1 and is 0.3-0.6mm wide is arranged at the position 0.5-1mm in the depth direction of the teeth of each main comb tooth 2 along the working edge, and a sickle-shaped needle point is formed between the concave platform and the back edge; meanwhile, four triangular ribs with the height of 0.1-0.2mm are arranged along the back edge at the position of 0.8-2mm downwards. The triangular edges of the back side are protruded at 45 degrees along the horizontal direction. As shown in fig. 2, the back triangular ribs are all between the first oblique line and the second oblique line of the tooth back and can be connected in a straight line or in an arc. The front edge of the teeth of the sickle needle point on the working edge is parallel to the working edge of the main comb teeth 2 and is connected with a horizontal line segment to form the sickle needle point. The triangular edge of the tooth back has the function of strengthening and holding the fiber, so that the fiber transferring process is kept on the layer surface of the doffer needle teeth, the control on the fiber during transferring is increased, the sickle plane in the sickle-shaped needle point is utilized, the forward direction is reversed in the operation, the carrying fiber is held forward, the falling flower is eliminated, and the transferring efficiency is greatly improved. The arrangement of the sickle needle point on the working side and the triangular edge on the back side doubles the transfer quantity of the doffer metal card clothing, thereby being beneficial to improving the output of the carding machine. The strip-out speed can be increased from 80-90m/min to 180-200m/min.
