Description

Technical Field

[0001] This utility model relates to the field of carding machine technology, and in particular to a cylinder metal needle cloth. Background Technology

[0002] The cylinder is the most important carding equipment in the carding machine. Its main function is to strip the fibers that have been initially carded by the licker-in roller and bring them into the cylinder cover area for further fine carding, straightening and uniform mixing, improving the separation, straightness and parallelism of the fibers, eliminating the front hooks of the cotton fibers, so as to improve the luster of the yarn and the spinnability of the next process.

[0003] In recent years, with the continuous development of science and technology, various metal card cloths with advanced structural designs and high-precision manufacturing have emerged, ensuring high-quality and high-yield carding machines. However, with the increase in output, the wear on the working surface has also intensified. The working surface of ordinary cylinder card cloth is a straight plane or an arc-shaped surface, with a concave arc connecting the working surface and the bottom surface. During the carding process, the fibers often cause concentrated wear at the connection between the working surface and the concave arc, forming grooves, which greatly reduces the carding effect and service life of the cylinder card cloth.

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cylinder metal needle cloth.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a cylinder metal needle cloth, comprising:

[0006] Base;

[0007] Several teeth arranged in an array are provided above the base;

[0008] The working surface of the tooth that contacts the material is set as a curved surface.

[0009] As a further description of the above technical solution: the tooth also includes a tooth tip, a tooth top surface, a tooth back surface, and a tooth bottom surface.

[0011] As a further description of the above technical solution: the curved surface of the tooth working surface is wavy, so that the tooth working surface forms several parallel and inwardly concave cavities.

[0012] As a further description of the above technical solution: the working surface of the tooth has at least two peaks and one trough.

[0013] As a further description of the above technical solution: the crests and troughs of the tooth working surface are both circular arcs with equal radii.

[0014] As a further description of the above technical solution: the radius of the peak and the trough ranges from 0.07 to 0.15 mm.

[0015] As a further description of the above technical solution: the crests of the several peaks of the tooth working surface are all on the same straight line, and the troughs of the several troughs are all on the same straight line.

[0016] As a further description of the above technical solution: the angle between the wave centerline of the tooth working surface and the vertical direction is α, and the value of the angle α is in the range of 20-50°.

[0018] The above technical solution has the following advantages or beneficial effects:

[0019] 1. The working surface of the tooth adopts a curved surface design, which can effectively distribute the combed fibers evenly on multiple points on the working surface, preventing the combed fibers from concentrating on a certain point on the working surface and causing concentrated wear, thereby effectively extending the service life of the cylinder card cloth.

[0023] 1. Base; 2. Tooth; 21. Working surface of tooth; 211. Crest; 212. Trough; 22. Tooth tip; 23. Tooth top surface; 24. Tooth back surface; 25. Tooth bottom surface. Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-2An embodiment of this utility model is provided: a cylinder metal needle cloth, comprising: a base 1; a plurality of teeth 2 arranged in an array above the base 1; the working surface 21 of the teeth 2 in contact with the material is configured as a curved surface.

[0026] In this embodiment, the tooth working surface 21 adopts a curved surface design, which can effectively distribute the combed fibers evenly to multiple points on the working surface, preventing the combed fibers from acting on a certain point on the working surface and causing concentrated wear, thereby effectively extending the service life of the cylinder card cloth. The curved surface design forms multiple peaks 211 and troughs 212, which can strengthen the holding effect on the fibers and improve the combing performance.

[0027] The tooth part 2 also includes a tooth tip 22, a tooth top surface 23, a tooth back surface 24, and a tooth bottom surface 25; the tooth top surface 23 and the tooth back surface 24 are connected by a convex curved surface, and the tooth back surface 24 and the tooth bottom surface 25 are connected by a concave curved surface.

[0028] In this embodiment, the fibers are combed by the tooth tip 22 and then combed from both sides of the tooth 2. The tooth top surface 23 and the tooth back surface 24 form an obtuse angle to support the tooth tip 22. The tooth back surface 24 and the tooth bottom surface 25 form an obtuse angle to support the tooth working surface 21, thereby enhancing the stress strength of the tooth 2. The tooth top surface 23 and the tooth back surface 24 are connected by a convex curved surface, and the tooth back surface 24 and the tooth bottom surface 25 are connected by a concave curved surface. The transition through the arc surface prevents damage to the combed fibers.

[0029] The curved surface of the tooth working surface 21 is wavy, which forms several parallel and inwardly recessed cavities on the tooth working surface 21. This prevents the combed fibers from acting on a certain point on the working surface and causing concentrated wear, thereby effectively extending the service life of the cylinder needle cloth.

[0030] The working surface 21 has at least two peaks 211 and one trough 212, forming a cavity for combing the fibers; the curved surface design forms multiple peaks and troughs, which can strengthen the gripping effect on the fibers and improve the combing performance.

[0031] The peaks 211 and troughs 212 of the working surface 21 are both circular arcs with equal radii, and the radii of the peaks 211 and troughs 212 range from 0.07 to 0.15 mm.

[0032] In this embodiment, the radii of the peaks 211 and troughs 212 are preferably 0.1 mm.

[0033] The crests of several peaks 211 on the working surface 21 of the tooth are all on the same straight line, and the troughs of several valleys 212 are all on the same straight line. The angle between the center line of the wave on the working surface 21 of the tooth and the vertical direction is α, and the value of the angle α is in the range of 20-50°.

[0034] In this embodiment, the crests of the wave peaks 211 are all on the same straight line, and the troughs of the wave valleys 212 are all on the same straight line, with the same inclination angle as the working surface 21. This ensures that the working surface 21 is subjected to balanced force during the combing process, reducing concentrated wear of the fibers on the working surface 21.

[0035] The base 1 and the tooth 2 are bonded or integrally connected.

[0036] In this embodiment, the base 1 and the tooth 2 are bonded together, allowing the tooth 2 to be disassembled for easy maintenance and replacement.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
