Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment technology, and more specifically, to a double cylinder fully fixed cover carding machine. Background Technology

[0002] Existing carding machines mainly include a feeding mechanism, a carding mechanism, a stripping mechanism, and a coiling mechanism, all connected sequentially. The carding mechanism typically includes a cylinder, though a double-cylinder structure is also possible. Multiple carding units, consisting of a work roller and a stripping roller paired together, are configured on the cylinder. While this carding structure offers the advantage of low fiber damage, it results in low carding degree and poor carding effect. Furthermore, the mechanical mechanism is relatively complex, leading to cumbersome maintenance and high operating costs. The feeding mechanism usually consists of a feed roller connected to a licker-in roller, which grips and feeds the fiber material for opening. This feeding process is prone to damaging the fiber raw material, thus affecting the final sliver quality. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0006] The primary combing mechanism includes an opening cylinder, the rear side of which is connected to the licker-in roller and the front side is connected to the transfer roller. The opening cylinder is circumferentially equipped with multiple sets of continuously arranged fixed cover plate opening units. Each set of fixed cover plate opening units includes at least two double fixed cover plates and a cotton web cleaner.

[0007] The carding mechanism includes a main cylinder, the main cylinder roller diameter is larger than the opening cylinder roller diameter, the rear side of the main cylinder is connected to the transfer roller, and the front side is connected to the doffer. The main cylinder is circumferentially equipped with multiple sets of continuously arranged fixed cover carding units, each set of fixed cover carding units includes at least three double fixed cover plates and a cotton web cleaner.

[0020] 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.

[0021] 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.

[0022] like Figure 1 As shown, a preferred embodiment of this utility model provides a double cylinder fully fixed cover carding machine, which includes a feeding mechanism 1, a licker-in roller 2, a primary carding mechanism, a transfer roller 3, a carding mechanism, a doffer 4, a stripping mechanism 5, and a coiler 6 arranged sequentially from back to front.

[0023] The feeding mechanism 1 includes a wool feeder, which includes a feeding box. The feeding box contains components such as a bottom flat curtain, an inclined nail curtain, a wool leveling rake, and a wool stripping roller. The specific structure is based on existing technology and will not be described in detail here. A wool feeder curtain 7 is connected to the front of the bottom of the wool feeder. A cotton feeding plate 8 is connected to the front end of the wool feeder curtain 7. A cotton feeding roller 9 is located above the cotton feeding plate 8. A pair of vertically arranged feeding rollers 10 are connected to the front of the cotton feeding plate 8 and are connected to the licker-in roller 2.

[0024] The general working process of the feeding mechanism 1 is as follows: the fiber raw material is processed by the feeding machine, and then conveyed by the feeding curtain 7. It is fed from above the feeding plate 8 and between the feeding roller 9 to make the fiber feeding more uniform. Then it is fed between the two feeding rollers 10 to pre-open the fiber. After that, it is peeled by the licker-in roller 2 and transferred to the next process. The above process can effectively reduce the damage to the fed fiber, and the fiber damage is less, thereby improving the quality of the sliver.

[0025] The primary carding mechanism includes an opening cylinder 11, the rear side of which is connected to the licker-in roller 2, and the front side of which is connected to the transfer roller 3. Multiple sets of continuously arranged fixed cover plate opening units are arranged circumferentially around the opening cylinder 11. In this embodiment, two sets are provided. Each set of fixed cover plate opening units includes at least two double-linked fixed cover plates 12 and a cotton web cleaner 13. In this embodiment, each set has two double-linked fixed cover plates 12 and one cotton web cleaner 13.

[0026] Furthermore, the comb needle density of each double fixed cover plate 12 in each set of fixed cover plate opening units is consistent, and the comb needle density of the double fixed cover plate 12 in the previous set of fixed cover plate opening units is greater than the comb needle density of the double fixed cover plate 12 in the next set of fixed cover plate opening units.

[0027] The carding mechanism includes a main cylinder 14, the diameter of which is larger than that of the opening cylinder 11. The rear side of the main cylinder 14 is connected to the transfer roller 3, and the front side is connected to the doffer 4. A cutting blade 15 is provided at the bottom of the transfer roller 3. The specific structure of the cutting blade 15 is based on existing technology and will not be described in detail here. Multiple sets of continuously arranged fixed cover carding units are arranged around the main cylinder 15. In this embodiment, six sets are provided. Each set of fixed cover carding units includes at least three double fixed cover plates 12 and one web cleaner 13. In this embodiment, each set has four double fixed cover plates 12 and one web cleaner 13.

[0028] Furthermore, the comb needle density of each double fixed cover plate 12 in each fixed cover plate combing unit is consistent, and the comb needle density of the double fixed cover plate 12 in the previous fixed cover plate combing unit is greater than the comb needle density of the double fixed cover plate 12 in the next fixed cover plate combing unit.

[0029] The aforementioned double-fixed cover plate 12 includes a fixed cover plate frame and two fixed cover plates arranged parallel to the fixed cover plate frame. Combing needles are provided on the bottom surface of the fixed cover plates. Each web cleaner 13 on the opening cylinder 11 and each web cleaner 13 on the main cylinder 14 are connected to a suction device (not shown in the figure).

[0030] In this embodiment, the fibers are first opened by a primary combing mechanism, and then combed by a combing mechanism. Both the opening cylinder 11 and the main cylinder 14 employ a fixed-cap combing method, which provides better combing performance compared to a driven combing unit consisting of work rollers and stripping rollers. Furthermore, the mechanical structure is simpler, maintenance is easier, and operating costs are lower. Additionally, the fixed-cap combing needles on the opening cylinder 11 and the main cylinder 14 adopt a progressive layout from sparse to dense, significantly reducing fiber damage and thus improving sliver quality.

[0031] The peeling mechanism 5 is a three-roller peeling mechanism located in front of the doffer, or a cleaver can be used.

[0032] The coiler 6 is a single-station or three-station automatic drum-changing coiler.

[0033] 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.
