Description

Technical Field

[0001] The utility model relates to the technical field of spinning, and particularly relates to a carding and impurity removing adjusting device. Background Art

[0002] A spinning device is provided with an impurity removing mechanism for removing impurities during the carding of a sliver. The impurity removing mechanism is beneficial to reducing the accumulated dust condensed in the spinning cup, increasing the dynamic strength of the peeling point, and reducing breakage. There are various types of impurity removing devices. Currently, the commonly used impurity removing devices on the market mainly fall into three categories: fixed small openings, fixed large openings, and impurity removing devices combining fixation and adjustment. The impurity removing efficiency of the fixed impurity removing device is constant, resulting in incomplete removal of impurities in long fiber raw materials and excessive removal of short fibers in short fiber raw materials, which affects the raw material utilization rate; in the fixed small opening impurity removing device, the air supplementing airflow and the impurity removing airflow interfere with each other, causing impurity blockage or impurity backflow, and this type of impurity removing device structure is only applicable to short fiber raw materials; the fixed large opening impurity removing device is only applicable to long fiber raw materials and has high requirements for the fiber length and uniformity of the raw materials. The impurity removing device combining fixation and adjustment is based on the fixed large opening impurity removing device, with an additional air supplementing channel, and a regulating valve is set in the air supplementing channel to control the size of the air supplementing amount. The impurity removing efficiency is controlled by adjusting the size of the air supplementing amount. Its structure is complex, and due to structural limitations, the adjustment of the impurity removing amount is limited. Therefore, this application develops a carding and impurity removing adjusting device to solve the problems existing in the prior art. Summary of the Utility Model

[0031] The following further describes the content of the present utility model in detail in conjunction with specific embodiments:

[0032] As Figure 1 - Figure 2As shown in the figure, a carding and impurity removal adjusting device includes a carding chamber housing 1, a carding roller 4, a cover plate 5, a wind deflector 6, and a negative pressure pipe 3. The carding roller includes a working part 41 and a driving part 42. The driving part 42 is rotatably arranged at one end of the driving part 42 and is located inside the carding chamber housing 1. The carding chamber housing 1 is also provided with a feed inlet 2, an impurity discharge port 7, and a negative pressure pipe 3. One end of the negative pressure pipe 3 is arranged inside the carding chamber housing 1, and the other end is connected to a negative pressure device. The cover plate 5 is fixed on the surface of the carding chamber housing 1, and an air supplement hole 53 is opened on the cover plate 5. The air supplement hole 53 is covered with a wind deflector 6. Materials enter the carding chamber housing 1 from the feed inlet 2. The working part 41 rotates at a high speed, and the negative pressure pipe 3 generates suction. By adjusting the position of the wind deflector 6, the opening size of the air supplement hole 53 is adjusted to control the size of the air supplement volume. When the supplemented flow rate is large, the gas flow rate is fast, and the generated resistance is large. When the supplemented flow rate is small, the gas flow rate is slow, and the generated resistance is small. At the same time, because the shapes of fibers and impurities are different, the windward area of fibers is larger, and the air flow resistance is also larger. By controlling the appropriate air flow speed, impurities within a specific weight range can be discharged without discharging fibers. However, when the air supplement volume is too large, smaller impurities will not be removed and will enter the chamber together with the fibers. When the air supplement volume is too small, some impurities cannot be effectively removed, affecting the impurity removal effect.

[0033] In this embodiment, as Figure 3 shown, an air supplement chamber 8 is formed between the inner surface of the cover plate 5 and the outer surface of the working part 41. The air supplement chamber 8 is communicated with the air supplement hole 53. When air is extracted through the negative pressure pipe 3, air enters the air supplement chamber 8 through the air supplement hole 53. The working part 41 rotates at a high speed, and fibers move inside the carding chamber housing 1 under the action of centrifugal force. At the same time, the air entering through the air supplement chamber 8 separates the impurities. The large area formed between the inner surface of the cover plate 5 and the outer surface of the working part 41 for the air supplement chamber 8 increases the flow area of the air flow, enabling a larger range of adjustment of the impurity discharge volume.

[0034] Further, the cover plate 5 includes a base part 51 and an extension part 52 that is smoothly connected to the base part 51. The base part 51 is circular, and the extension part 52 extends along the four peripheral edges of the base part 51 towards the carding chamber housing 1 and contacts the carding chamber housing 1. Wherein, the connection between the base part 51 and the extension part 52 is arranged in an arc shape, making the air supplement chamber 8 an overall annular chamber. The air flow enters the air supplement chamber 8 from the air supplement hole 53 and flows into the carding chamber housing 1 along the inner side surface of the air supplement chamber 8, which is beneficial to the smooth flow of the air flow, reduces eddies and turbulence generated due to irregular shapes, thereby reducing the flow resistance, improving the air supplement efficiency, and ensuring the uniform distribution of the air supplement air flow in all directions, which is beneficial to the stability of the air flow inside the carding chamber housing 1 and improves the impurity removal effect.

[0035] Further, as Figure 3 - Figure 4As shown, there is a gap between the outer side surface of the working part 41 and the inner side surface of the carding chamber housing 1, forming an annular channel 9. The gas enters the carding chamber housing 1 through the annular channel 9 via the air supply chamber 8, enabling the air to vertically enter the chamber formed between the driving part 42 and the carding chamber housing 1. This can make the air more evenly distributed on the chamber surface, avoiding the problem of uneven fiber separation caused by uneven air flow distribution, helping to more finely separate the fibers in the sliver into single fiber state, improving the carding efficiency. And the vertically entering air flow forms a negative pressure or air flow in the chamber, which can generate an additional adsorption force to help adsorb and separate the fibers and impurities in the sliver, further improving the carding efficiency, helping to reduce the unevenness of fiber thickness in the fibers, improving the overall quality of the fibers. The vertically entering air flow can also more effectively suck away the impurities and short fibers in the sliver, reducing the breakage and dust accumulation caused by impurities, reducing the number of defects in the fibers, and improving the purity and quality of the fibers.

[0036] To better adjust the size of the air supply hole 53, as Figure 5 shown, one side of the wind deflector 6 in contact with the cover plate 5 is provided with a boss 61. The boss 61 is inserted into the air supply hole 53. The wind deflector 6 is rotatably connected to the center of the surface of the cover plate 5. When the wind deflector 6 rotates, the boss 61 moves in the air supply hole 53, thereby adjusting the shielding range of the wind deflector 6. By rotating the wind deflector 6 to cover the air supply hole 53 and adjusting the size of the communication between the air supply hole 53 and the outside air, the air supply volume is adjusted. Among them, the radial dimension of the boss 61 is adapted to that of the air supply hole 53, so that when the boss 61 moves along the path of the air supply hole 53, it can be relatively sealed, and the air supply volume can be controlled more precisely. When the boss 61 moves to both ends of the air supply hole 53, the air supply hole 53 is in a fully open or covered state. By controlling the opening and closing state of the air supply hole 53, the pressure in the carding chamber housing 1 is adjusted to keep it within a suitable range.

[0037] The volume of the air supply chamber 8 is larger than the intake air volume that enters the air supply chamber 8 through the air supply hole 53 within 1 minute when the air supply hole 53 is in a fully open state. The relatively large volume of the air supply chamber 8 can serve as an air flow buffer zone to slow down the impact of sudden changes in the outside air flow on the carding area. When the air supply hole 53 is fully open, although the intake air volume is large, the volume of the air supply chamber 8 can absorb these air flows, avoiding the direct impact of the air flow on the carding area, causing fiber scattering or unstable carding. At the same time, it can also maintain the uniformity and stability of the air flow to a certain extent, helping to ensure the stable operation of the carding roller 4 and improving the carding quality.

[0038] To more precisely control the amount of impurity removal, the cover plate 5 is evenly provided with scales, and the wind deflector 6 is provided with a pointer corresponding to the scales. By controlling the size of the air supplement amount through the pointer at the corresponding position, by setting evenly distributed scales on the cover plate 5 and installing a pointer corresponding to the scales on the wind deflector 6, the operator can intuitively see the opening and closing degree of the current air supplement hole 53 or the size of the air flow channel. By adjusting the position of the wind deflector 6 to make the pointer point to different scales, the size of the air supplement amount can be precisely controlled. Different fiber types, impurity contents, and carding process requirements may require different air supplement amounts. By precisely adjusting the air supplement amount, the air flow in the carding area can be ensured to be stable and meet the process requirements, thereby improving the carding efficiency and effect.

[0039] The implementation principle of this embodiment:

[0040] When removing impurities, the sliver enters from the feed port 2, and the negative pressure device starts to draw air through the negative pressure pipe 3. At the same time, rotate the air baffle according to the impurities to be removed. The air baffle rotates to block the air supplement hole 53 provided on the cover plate 5 and rotates to the corresponding position according to the corresponding pointer and scale. The driving part 42 in the carding roller 4 drives the working part 41 to rotate. Air enters the air supplement cavity 8 through the upper air supplement hole 53, and the gas enters the annular channel 9 along the inner side surface of the air supplement cavity 8, so that the air flow enters the cavity formed between the driving part 42 and the carding cavity housing 1 evenly and vertically, improving the carding efficiency. At the same time, the air supplement cavity 8 increases the flow area of the air flow, and cooperates with the air supplement hole 53 to realize the adjustment of a larger range of impurity removal amounts, thereby improving the impurity removal efficiency, and enabling the impurities to be discharged from the impurity discharge port 7 under the action of centrifugal force.
