Description

Technical Field

[0001] The present invention relates to the technical field of textile equipment, and particularly to an electrostatic adsorption type foreign fiber removal device. Background Art

[0002] In the spinning process, foreign fibers (such as chemical fibers, hairs, plastics, etc.) mixed in the spinning raw cotton will seriously affect the quality of yarns and fabrics. Therefore, removing foreign fibers is a key link in the pre-treatment of spinning. Currently, common removal methods mainly include manual picking, mechanical carding, air flow sorting, and ultrasonic removal, etc.

[0003] Manual picking is the most traditional method. This method is simple and direct, but has low efficiency, high cost, and is easily affected by worker fatigue. The method of mechanical carding combined with air flow sorting uses mechanical actions such as striking and carding to remove some foreign fibers, and blows them out with air flow. This method has high efficiency, but has limited removal effect on fine foreign fibers or foreign fibers with characteristics similar to cotton fibers. The ultrasonic removal method is through vibration sorting, and has limited removal effect on fine foreign fibers. In addition, the existing methods for removing foreign fibers may break fibers in the carding process, causing the fibers to break into countless small defect points and mix into the sliver, interfering with the continuity of subsequent processing and resulting in deterioration of the quality of textiles.

[0059] Cotton is one of the important commercial crops in human life. During the processes of cotton picking, transportation, processing, and storage, various foreign fibers may be mixed in. Generally, they can be divided into hair-like (such as hair, horse mane, wool, etc.), strip-like (such as colored threads, cloth strips, feathers, polypropylene filaments, hemp ropes, etc.), and sheet-like (such as plastic sheets, cloth pieces, paper pieces, etc.). These foreign fibers in the raw cotton for spinning are mixed in the raw cotton for spinning, adhered and entangled with cotton fibers to form bundles. During the spinning process, they are not only difficult to remove, but also will be broken, smashed, or combed into countless fibrous small defects and mixed into the yarn in the carding process. These small defects are extremely likely to interfere with the subsequent process flow and greatly reduce the production efficiency.

[0060] Refer to Figure 1 、 Figure 2 and Figure 4In one embodiment of the present invention, an electrostatic adsorption type foreign fiber removal device is disclosed, which is used to remove foreign fibers in spinning raw cotton; wherein, it includes an adsorption roller 10 and an electrostatic field component 20, along the rotation direction of the adsorption roller 10, the top of the adsorption roller 10 is a feeding position 11, the front end of the adsorption roller 10 is a discharging position 12, and a removal channel 13 is formed between the feeding position 11 and the discharging position 12, and the removal channel 13 is used to pass the spinning raw cotton; the electrostatic field component 20 is arranged on the side of the removal channel 13 away from the adsorption roller 10; a corona electrode 21 is provided on the side of the electrostatic field component 20 facing the removal channel 13, and the corona electrode 21 is used to discharge to ionize the air in the removal channel 13 to charge the foreign fibers; the adsorption roller 10 is grounded and used to adsorb the charged foreign fibers.

[0061] The foreign fiber removal device disclosed in this embodiment is provided with an adsorption roller 10, and the raw cotton for spinning is transported by the rotational friction force of the adsorption roller 10. Figure 3 As shown, the adsorption roller 10 is fixed by a frame 14, and an industrial motor 15 is arranged at the end of the adsorption roller 10, and the industrial motor 15 drives the adsorption roller 10 to rotate continuously.

[0062] It should be noted that this embodiment only exemplifies the driving method of the adsorption roller 10 and is not exhaustive. The protection scope of the present invention is not limited to this. Other types of driving methods can achieve the technical effect of driving the adsorption roller 10 to rotate. As an equivalent replacement of the concept of the present invention, they should also be within the scope of protection of this application.

[0063] Specifically, in this embodiment, the feeding position 11 is at the top of the adsorption roller 10, and the spinning raw cotton enters the cleaning channel 13 from the feeding position 11, falls to the surface of the adsorption roller 10 due to the influence of gravity, and is driven to the front end of the adsorption roller 10 by the friction force on the surface of the adsorption roller 10; then, at the discharging position 12, the spinning raw cotton loses support, falls from the adsorption roller 10, and is naturally separated.

[0064] In this embodiment, the electrostatic field component 20 is arranged on one side of the cleaning channel 13. The discharge is carried out through the corona electrode 21. The air molecules are ionized under the action of the electric field to produce positive ions and electrons. Since the spinning raw cotton has poor conductivity and cannot transfer charges quickly, it will absorb positive ions and carry positive electricity; while the heterosexual fibers will absorb electrons and carry negative electricity.

[0065] At the same time, the adsorption roller 10 is grounded, so when the charged foreign fibers approach the adsorption roller 10, electrostatic induction occurs, and the surface of the adsorption roller 10 senses the opposite charge of the foreign fibers, generating an attraction for the foreign fibers, so that the foreign fibers are adsorbed on the surface of the adsorption roller 10 and will not be sent out from the discharge position 12, thereby achieving the effect of separating the spinning raw cotton and the foreign fibers.

[0066] Particularly, in this embodiment, the electrostatic adsorption method can keep the foreign fibers intact during cleaning, thereby reducing the problem of residual defect points in the spinning raw cotton, improving work efficiency, having high production quality, and being conducive to improving the continuity of production.

[0067] Specifically, as another embodiment of the present application, it is disclosed that the adsorption roller 10 is a beryllium copper alloy roller made of beryllium copper material. Beryllium copper material has the characteristics of high electrical conductivity, high thermal conductivity, high temperature resistance, and wear resistance. In this application, an electrostatic field is generated on the surface of the adsorption roller 10 and needs to be grounded. Therefore, the adsorption roller 10 made of beryllium copper material can not only meet the requirements of production and processing but also improve the service life and reduce the equipment maintenance cost.

[0068] As Figure 4 and Figure 5 shown, as another embodiment of the present application, it is disclosed that the electrostatic field assembly 20 includes an arc-shaped housing 22, a copper wire 24, a negative electrode lead 25, and a DC power supply 26. The arc-shaped housing 22 is concentrically arranged with the adsorption roller 10; the arc-shaped housing 22 covers the side of the cleaning channel 13 facing away from the adsorption roller 10, and the inside of the arc-shaped housing 22 is hollow, forming an inner cavity 221; an installation hole is provided on the side of the arc-shaped housing 22 facing the cleaning channel 13, and the installation hole communicates with the inner cavity 221. The copper wire 24 is arranged in the inner cavity 221; one end of the negative electrode lead 25 is connected to the copper wire 24, and the other end is externally connected to the DC power supply 26. A plurality of corona electrodes 21 are provided, and the plurality of corona electrodes 21 are arranged at intervals on the copper wire 24. A plurality of installation holes are provided, and the plurality of installation holes are arranged at intervals along the extension path of the copper wire 24; the corona electrodes 21 are inserted into the installation holes and partially extend into the cleaning channel 13.

[0069] In this embodiment, power is supplied by the DC power supply 26. Preferably, a high-voltage DC power supply is used. The negative high voltage generated by the high-voltage DC power supply is connected to the corona electrode 21 through the negative electrode lead 25 and the copper wire 24, generating an electrostatic field in the cleaning channel 13. When the electric field strength exceeds the limit, corona discharge occurs. At this time, the gas flowing through the electric field area is ionized, generating a large number of positive ions and electrons.

[0070] Specifically, the shape of the surface of the adsorption roller 10 is arc-shaped, and the arc-shaped housing can fit the shape of the adsorption roller 10 to completely cover the cleaning channel 13. For example, the cleaning channel 13 extends from the top end (feeding position 11) of the adsorption roller 10 to the front end (discharging position 12), and the length is one-fourth of the circumference of the adsorption roller 10. The arc-shaped housing 22 can be set in the shape of a quarter circle and is suspended and fixed on one side of the entire cleaning channel 13 through a fixing frame 23, thereby generating a large-range electrostatic field to cover the spinning raw cotton in the entire cleaning channel 13, improving the removal efficiency of foreign fibers, and reducing the situation of omission.

[0071] Specifically, the arc-shaped housing 22 is concentrically arranged with the adsorption roller 10, and the width of the cleaning channel 13 formed between the arc-shaped housing 22 and the adsorption roller 10 is uniform. That is to say, the intensity of the electrostatic field at each position is the same, which is conducive to the sorting effect of the whole surface, more completely removing the opposite-sex fibers, and improving the working quality of the equipment.

[0072] In another embodiment of this embodiment, it is disclosed that the arc-shaped housing 22 is a silicone rubber housing. The silicone rubber material has excellent insulation performance and high and low temperature resistance, which can protect the copper wire 24 and the corona electrode 21 and improve the safety of equipment use. One side of the arc-shaped housing 22 is insulated, while the adsorption roller 10 is made of beryllium copper material and is conductive. Therefore, the opposite-sex fibers will only be adsorbed on the surface of the adsorption roller 10 and will not run onto the arc-shaped housing 22, improving the sorting efficiency. In addition, in this embodiment, the negative lead 25 can be made of an epoxy resin-wrapped conductive wire, and the insulation performance of the epoxy resin is used to further improve the safety of equipment use.

[0073] In another embodiment of this embodiment, it is disclosed that the distance between the surface of the arc-shaped housing 22 and the adsorption roller 10 is 5-8 cm. In this embodiment, if the distance between the arc-shaped housing 22 and the adsorption roller 10 is too close, it is easy to cause a short-circuit problem, which may lead to equipment failure; if the distance between the arc-shaped housing 22 and the adsorption roller 10 is too far, it will cause insufficient electric field strength and affect the cleaning efficiency. Therefore, in this embodiment, the distance between the arc-shaped housing 22 and the adsorption roller 10 is controlled to be 5-8 cm.

[0074] In this embodiment, the distance between the surface of the arc-shaped housing 22 and the adsorption roller 10 can be any value between 5-8 cm or the range between any two values, such as 5 cm, 5.5 cm, 6 cm, 7 cm, 8 cm, etc. Preferably, the distance between the arc-shaped housing 22 and the adsorption roller 10 is set to 6 cm.

[0075] Specifically, in this embodiment, the cleaning channel 13 has a certain width and length. Therefore, a plurality of corona electrodes 21 are provided, and the plurality of corona electrodes 21 are welded to the copper wire 24 at intervals and extend into the cleaning channel 13 in cooperation with a plurality of mounting holes, so as to improve the uniformity of the electric field strength of the electrostatic field, make the electrostatic adsorption ability at each place in the cleaning channel 13 tend to be consistent, and maintain an excellent adsorption effect.

[0076] Again Figure 1 and Figure 2 As shown, as another embodiment of the present application, it is disclosed that the electrostatic adsorption type opposite-sex fiber cleaning device includes a collector 30, and the collector 30 is arranged below the adsorption roller 10 for collecting opposite-sex fibers.

[0077] When the foreign fiber rotates to the lower part of the adsorption roller 10, affected by its own gravity and the centrifugal force generated by the rotation of the adsorption roller 10, it overcomes the suction force on the surface of the adsorption roller 10 and drops off. Therefore, the collector 30 is provided to collect the foreign fibers in a timely manner for convenient centralized transfer and cleaning.

[0078] Specifically, during the cleaning process, it is not excluded that a small number of extremely small foreign fibers, due to their light mass, remain adsorbed on the surface of the adsorption roller 10 and cannot fall off naturally, and may return to the cleaning channel 13 again as the adsorption roller 10 rotates. At this time, it is necessary to adjust the rotation speed of the adsorption roller 10 to remove them with the help of greater centrifugal force or with the help of external force.

[0079] Another example Figure 1 and Figure 2 As shown, as another embodiment of the present application, the electrostatic adsorption type foreign fiber cleaning device is disclosed to include a brush 40, and the brush 40 is arranged on the side of the adsorption roller 10 away from the electrostatic field assembly 20; the brush 40 is in contact with the adsorption roller 10 and is used to sweep away foreign fibers; the brush 40 is located directly above the collector 30. In this embodiment, the brush 40 is provided to directly clean the foreign fibers on the surface of the adsorption roller 10, so as to efficiently remove the residues on the surface of the adsorption roller 10, and the brush 40 is located above the collector 30, and the foreign fibers brushed off by the brush 40 directly fall into the collector 30, which can be quickly collected.

[0080] Such as Figure 6 As shown, as another embodiment of the present application, the collector 30 is disclosed to include a supporting power supply 31, a collection box 32 and a positive lead 33, and the collection box 32 is used to store foreign fibers; one end of the positive lead 33 is connected to the supporting power supply 31, and the other end is connected to the collection box 32.

[0081] The foreign fibers disclosed in this embodiment are negatively charged. If directly collected and processed, they are easily interfered by static electricity and pose a danger. The supporting power supply 31 disclosed in this embodiment includes but is not limited to a high-voltage DC power supply. During collection, by turning on the supporting power supply 31 and connecting it to the collection box 32 through the positive lead 33, the foreign fibers in the collection box 32 are adsorbed and the surface static electricity is removed, so as to facilitate safe transportation and cleaning.

[0082] Such as Figure 7As shown, as another embodiment of the present application, the electrostatic adsorption type foreign fiber removing device is disclosed, which includes a feeding assembly 50 that aligns with the feeding position 11; the feeding assembly 50 includes a first bracket 51, a first conveyor belt 52, a first motor 54, a first chain 56, and a first power supply 57. The first conveyor belt 52 is arranged on the first bracket 51, and the rotation direction of the first conveyor belt 52 is the same as that of the adsorption roller 10; the conveying direction of the first conveyor belt 52 faces the feeding position 11; and a first synchronous roller 53 is provided on the driving roller shaft of the first conveyor belt 52; the first motor 54 is arranged on the first bracket 51; a first driving roller 55 is sleeved on the output shaft of the first motor 54; one end of the first chain 56 is sleeved on the first driving roller 55, and the other end is sleeved on the first synchronous roller 53; the first power supply 57 is electrically connected to the first motor 54; wherein, the first bracket 51 is grounded.

[0083] In this embodiment, the adsorption roller 10 is fixed by the frame 14 and maintained at a certain height. The feeding position 11 is at the top of the adsorption roller 10. Therefore, the first bracket 51 is set as a support, and the top surface of the first bracket 51 is flush with the feeding position 11 to horizontally arrange the first conveyor belt 52. The first power supply 57 can be a storage battery to provide power to the first driving roller 55. The power is transmitted to the first synchronous roller 53 through the first chain 56 to achieve the effect of driving the first conveyor belt 52 to rotate continuously. Therefore, the spinning raw cotton can be continuously conveyed to meet the continuity of the cleaning work.

[0084] Specifically, the feeding assembly 50 disclosed in this embodiment is used to align and feed the spinning raw cotton with foreign fibers into the feeding position 11. Since it is close to the electrostatic field, the first bracket 51 is grounded to avoid electrostatic interference.

[0085] As Figure 8As shown, as another embodiment of the present application, the electrostatic adsorption type foreign fiber removal device is disclosed, which includes a discharge assembly 60 that aligns with the discharge position 12. The discharge assembly 60 includes a second bracket 61, a second conveyor belt 62, an inclined baffle 64, a second motor 65, a second chain 67, and a second power source 68. The second conveyor belt 62 is disposed on the second bracket 61, and the rotation direction of the second conveyor belt 62 is the same as that of the adsorption roller 10. Moreover, a second synchronous roller 63 is provided on the transmission roller shaft of the second conveyor belt 62. The inclined baffle 64 is disposed on the second bracket 61 and is located above the second conveyor belt 62. One end of the inclined baffle 64 aligns with the discharge position 12, and the other end extends towards the second conveyor belt 62. The second motor 65 is disposed on the second bracket 61. A second transmission roller 66 is sleeved on the output shaft of the second motor 65. One end of the second chain 67 is sleeved on the second transmission roller 66, and the other end is sleeved on the second synchronous roller 63. The second power source 68 is electrically connected to the second motor 65. Among them, the second bracket 61 is grounded.

[0086] In this embodiment, the adsorption roller 10 is fixed by the frame 14 and maintained at a certain height. The discharge position 12 is at the front end of the adsorption roller 10 and has a certain height. Therefore, the inclined baffle 64 is provided to collect and guide the spinning raw cotton from which the foreign fibers have been removed to the second conveyor belt 62. The second bracket 61 serves as a support, and the second conveyor belt 62 can be horizontally arranged. The second power source 68 can be a storage battery, providing power to the second transmission roller 66. The power is transmitted to the second synchronous roller 63 through the second chain 67 to achieve the effect of driving the second conveyor belt 62 to continuously rotate, so that the spinning raw cotton can be continuously sent out to meet the continuity of the cleaning work.

[0087] Specifically, since the discharge assembly 60 disclosed in this embodiment is close to the electrostatic field, the second bracket 61 is grounded to avoid electrostatic interference and at the same time conduct the static electricity on the positively charged spinning raw cotton on the second conveyor belt 62.

[0088] It can be seen that in this embodiment, by arranging the feeding assembly 50 and the discharge assembly 60 on both sides of the adsorption roller 10, the cleaning work of the spinning raw cotton can be continuously carried out, facilitating continuous production and processing and improving production efficiency.

[0089] Specifically, as another embodiment of the present application, it is disclosed that the first conveyor belt 52 is made of antistatic polyvinyl chloride material; or, the second conveyor belt 62 is made of antistatic polyvinyl chloride material; or, both the first conveyor belt 52 and the second conveyor belt 62 are made of antistatic polyvinyl chloride material.

[0090] In this embodiment, the antistatic effect of polyvinyl chloride material is used to make the first conveyor belt 52 and the second conveyor belt 62, which can reduce the impact of static electricity, improve the safety of equipment use, and avoid interfering with the removal process of foreign fibers.
