Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and more specifically, to a cashmere pre-opening device. Background Technology

[0002] During the cashmere carding process, pre-opening and impurity removal are necessary to meet the feeding requirements of cashmere carding equipment. Existing pre-opening and impurity removal equipment is generally an opening machine with a built-in vibrating bar for impurity removal. This equipment struggles to meet the purity and looseness requirements of complete cashmere carding equipment and has low efficiency. Furthermore, the removed impurities cannot be discharged promptly, leading to their reintegration, reduced textile quality, and increased production costs for enterprises.

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

[0005] Cashmere pre-opening equipment includes a five-roller opening mechanism, a wool-binding mechanism, and a single-axial flow opening mechanism connected in sequence from front to back;

[0006] The five-roller opening mechanism includes a first flat curtain, one end of which is provided with a first opening roller. The first flat curtain and the first opening roller are connected by a first feeding roller assembly. On the side of the first opening roller away from the first feeding roller assembly, there are four second opening rollers arranged at an angle of 45° upwards. The diameter of the first opening roller is larger than the diameter of the second opening roller.

[0007] The five-roller opening mechanism and the wool gathering mechanism are connected by a first wool conveying pipe, on which a first conveying fan is installed. The wool gathering mechanism and the single-axial flow opening mechanism are connected by a second wool conveying pipe, on which a second conveying fan is installed.

[0011] Preferably, the work roll assembly includes a work roll and a stripping roll connected together.

[0012] Preferably, the single-axial flow opening mechanism includes a box-type housing, an impactor installed inside the box-type housing, a dust grid at the bottom of the impactor, and a cover at the top of the impactor. The cover, the inner wall of the box-type housing, and the dust grid enclose a dust removal chamber. The top of the box-type housing has an inlet and an outlet spaced apart along the length of the impactor. Both the inlet and outlet are connected to the dust removal chamber. The bottom of the dust grid has a hopper that is wider at the top and narrower at the bottom. The bottom of the hopper is connected to a cylindrical dust collection chamber. The dust collection chamber has a wing roller. The side wall of the dust collection chamber has a dust outlet.

[0018] 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.

[0019] 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.

[0020] like Figure 1 As shown, a preferred embodiment of the present invention provides a cashmere pre-opening device, which includes a five-roller opening mechanism 1, a wool-binding mechanism 2, and a single-axial flow opening mechanism 3 connected in sequence from front to back.

[0021] The five-roller opening mechanism 1 includes a first flat curtain 4, with a first opening roller 5 at one end. The first flat curtain 4 and the first opening roller 5 are connected by a first feeding roller assembly, which includes a pair of vertically arranged feeding rollers 6. Four second opening rollers 7 are arranged at a 45° angle upwards on the side of the first opening roller 5 away from the first feeding roller assembly. The purpose of this 45° upward arrangement is to allow large impurity particles in the fiber to fall naturally during the opening process, achieving a certain impurity removal effect. The diameter of the first opening roller 5 is larger than the diameter of the second opening rollers 7, which helps to increase the fiber feeding amount and thus improve efficiency.

[0022] The opening mechanism adopts a five-roller design, in which the fibers are gradually transferred and opened at an angle along the arrangement direction of the rollers. Compared with the existing single-roller opening equipment, the opening effect is better and the damage rate to the fibers is lower.

[0023] The five-roller opening mechanism 1 and the wool gathering mechanism 2 are connected by a first wool conveying pipe 8, and a first conveying fan 9 is installed on the first wool conveying pipe 8.

[0024] The fiber-combining mechanism 2 includes a cyclone separator 10, with a second flat curtain 11 below the cyclone separator 10. A cylinder 12 is located at one end of the second flat curtain 11. The cylinder 12 and the second flat curtain 11 are connected by a second feed roller assembly. The second feed roller assembly includes a feed cleaning roller 13, an upper feed roller 14, and a lower feed roller 15 arranged sequentially from top to bottom. At least two sets of working roller assemblies are spaced apart around the cylinder 12. Each set of working roller assemblies includes a connected working roller 16 and a stripping roller 17. A doffer 18 is located on the side of the cylinder 12 away from the second feed roller assembly. The fiber-combining mechanism 2 is mainly used to further open and comb the fibers that have been initially opened by the five-roller opening mechanism 1.

[0025] The wool-forming mechanism 2 and the single-axial flow opening mechanism 3 are connected by a second wool-feeding pipe 19, on which a second conveying fan 20 is installed.

[0026] The single-axial flow opening mechanism 3 includes a box-type housing 21. A beater is installed inside the box-type housing 21, and a dust grid is located at the bottom of the beater. A cover is located inside the box-type housing 21 and above the beater. The cover, the inner wall of the box-type housing, and the dust grid enclose a dust removal chamber. An inlet 22 and an outlet 23 are spaced apart along the length of the beater at the top of the box-type housing 21, and both the inlet 22 and outlet 23 are connected to the dust removal chamber. A hopper, wider at the top and narrower at the bottom, is located inside the box-type housing 21 and below the dust grid. A cylindrical dust collection chamber is connected to the bottom of the hopper. A leather-wing roller 24 is located inside the dust collection chamber, and a dust outlet is located on the side wall of the dust collection chamber. A dust outlet pipe 25 is vertically located on the side of the box-type housing 21 and is connected to the dust outlet.

[0027] The single-axial flow opening mechanism 3 is mainly used to remove impurities and open fibers, and ultimately meet the feeding requirements for fiber purity and looseness.

[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.
