Problems solved by technology

However, due to the existence of the covering side angle, the front face of the sawtooth does not face the cotton layer, which will seriously affect the carding quality, and because of the impact of the obtuse side on the cotton layer, it is not easy to effectively card the cotton layer, but it is easy to rub Neps are produced, and the cotton layer is torn to produce a large amount of short fibers, which is not conducive to the effective use of saw teeth

Embodiment Construction

[0016] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0017] Such as Figure 1a and Figure 1b As shown, when the rack 2 is coated on the surface of the licker-in roller 1, it forms an angle α with the edge, so that as Figure 1b The saw teeth 3 on the toothed rack 2 are also shown to produce a lateral angle α. As a result, when the transverse cotton layer is carded, the sawtooth 3 that should be completely facing the face 6 has adopted the sawtooth side with a side angle α for carding. The side angle α blunts the sharpness that the sawtooth 3 should have on the cotton layer, and the cotton layer does not get the maximum carding of the licker-in roller sawtooth, but the side of the sawtooth beats the cotton layer, which also affects the cotton layer. Tearing has occurred, and the incomplete carding of the gripped cotton layer will lead to an increase in fiber linters and fragmentat...

Abstract

The invention relates to a licker-in high efficiency metal saw blade; the saw blade wraps the surface of a licker-in, and forms an angle [alpha] with the licker-in edge; the saw blade comprises a base body; the base body bottom plane is vertical to the vertical plane; the base body is provided with saw teeth; the features are that the needle height plane of each saw tooth and the vertical plane form an angle [beta], wherein the angle [beat] equal to angle[alpha]. The high efficiency carding licker-in saw blade with certain angle is provided; compared with the prior art and under same saw teeth density, each saw tooth of the novel saw blade employs complete front edge carding, and abandons existing side angle carding problems, thus reducing channelizing phenomenon in carding fiber current, improving fiber (group) bundle effective carded probability, effectively improving carding quality, and maximumly reducing fiber damages.

Description

technical field [0001] The invention relates to a high-efficiency carding metal saw blade, which is suitable for a licker-in roller of a carding machine and belongs to the textile field. Background technique [0002] As one of the main carding components of the carding machine, the licker-in roller is the only holding and carding device on the carding machine. The quality of its function will directly affect the carding quality of the cylinder flat area and the life of the saw blade, and finally affect the cotton web. Improvements in clarity, sliver inclusion, sliver linters and card output. Licker-in saw blades are generally divided into groove type and self-locking type. At present, the self-locking type has gradually replaced the groove type and become the mainstream. The adjacent racks of the self-locking rack are interlocked, making it strong in anti-rolling and fracture resistance, and its sawtooth can change the tooth bottom width according to different carding obje...
