Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and more specifically, to a double-tin flax fiber combing machine. Background Technology

[0002] Existing carding machines mainly include a feeding mechanism, a carding mechanism, a stripping mechanism, and a coiling mechanism, with each mechanism connected sequentially. The carding mechanism is a double-cylinder structure, including an opening cylinder and a main cylinder. The opening cylinder has 2-3 pairs of working roller assemblies, and the main cylinder has 5-7 pairs of working roller assemblies. This carding structure causes minimal fiber damage but results in low carding intensity and poor carding effect. To address these issues, invention patent CN101372769A discloses a wool semi-worsted carding machine. The main cylinder uses a fully movable cover plate carding method, which improves the carding effect but exacerbates fiber damage, especially to hemp fibers that do not require strong carding.

[0003] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0004] The purpose of this utility model is to provide a double-tin-lined hemp fiber carding machine, aiming to solve at least one of the technical problems existing in the prior art. To achieve the above objective, the technical solution adopted is as follows:

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1 As shown, a preferred embodiment of this utility model provides a double-staling hemp fiber carding machine, which includes a feeding mechanism 1, a licker-in roller 2, an opening mechanism, a transfer roller 3, a carding mechanism, a doffer 4, a stripping mechanism 5, and a coiler arranged sequentially from back to front.

[0022] The feeding mechanism 1 includes an automatic feather feeder, which includes a feeding box containing components such as a bottom flat curtain, an inclined nail curtain, a feather leveling rake, and a feather stripping roller. The specific structure is based on existing technology and will not be described in detail here. A feather feeding flat curtain 6 is connected to the front bottom of the automatic feather feeder, and a four-roller feeding structure 7 is connected to the front end of the feather feeding flat curtain 6. Specifically, the four-roller feeding structure includes two pairs of feeding roller assemblies arranged front to back. Each pair of feeding roller assemblies includes two feeding rollers arranged vertically. The pair of feeding roller assemblies located at the front is connected to the licker roller 2.

[0023] The opening mechanism includes an opening cylinder 8, the rear side of which is connected to the licker roller 2, and the front side of which is connected to the transfer roller 3. The opening cylinder 8 has three sets of work roller assemblies spaced apart in the circumferential direction. Each set of work roller assemblies includes a stripping roller 9 and a work roller 10 arranged sequentially from back to front and cooperating with each other.

[0024] The cylinder is provided with a rear wind deflector roller 11 and a front wind deflector roller 12 on the 8th circumference. Specifically, the rear wind deflector roller is located between the piercing roller 2 and the rearmost group of the three working roller assemblies on the cylinder, while the front wind deflector roller 12 is located between the frontmost group of the three working roller assemblies on the cylinder and the transfer roller 3.

[0025] The carding mechanism includes a main cylinder 13, whose roller diameter is larger than that of the opening cylinder 8. The rear side of the main cylinder 13 is connected to the transfer roller 3, and the front side is connected to the doffer 4. From back to front, the main cylinder 13 is arranged with a working roller carding area 14, a movable flatbed carding area 15, and a fixed flatbed carding area 16. The working roller carding area 14 includes two sets of working roller assemblies spaced apart. The working roller assemblies on the main cylinder and the opening cylinder have the same structure and function—carding the fibers. The movable flatbed carding area 15 has 17-20 movable flatbeds. The fixed flatbed carding area 16 has 4-6 fixed flatbeds. Additionally, a web cleaner 17 is provided, which is connected to a suction device (not shown in the figure).

[0026] The stripping mechanism 5 is a three-roller stripping mechanism located in front of the doffer, or it can be a cutter. The coiler (not shown in the figure) is a single-station or three-station automatic drum-changing coiler.

[0027] This carding machine is mainly used for hemp fibers that do not require strong carding. During operation, the hemp fibers are fed in through the feeding mechanism 1, and then pass through three sets of working rollers on the opening cylinder 8 for opening and carding. The opening cylinder 8 causes minimal fiber damage, but the carding effect is relatively poor. Next, the fibers enter the main cylinder 13, first passing through the working roller carding zone 14, where two sets of working rollers further open and card them, preparing them for the next step in the movable cover carding zone 15. The main function of this zone is to reduce damage to the hemp fibers during the relatively strong carding process in the movable cover carding zone. Finally, the fibers enter the fixed cover carding zone 16, where the fixed cover performs the final finishing. The fixed cover has a simpler structure than the working roller assembly and the movable cover, and is easy to install and remove. Users can replace the fixed cover with different carding needle densities according to the hardness of the hemp fibers, ensuring good carding effect and minimal damage. Afterwards, the fibers pass through the doffer and stripping mechanism into a coiler to form slivers.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
