Description

Technical Field

[0001] The present invention belongs to the technical field of cashmere processing, and specifically relates to an automated continuous operation cashmere carding device. Background Art

[0002] Cashmere is a thin layer of fine hair growing on one side of the root of the coarse hair of goats. When processing cashmere, it is necessary to remove impurities such as dandruff in the cashmere through carding to form pure cashmere. In the existing carding devices, cashmere is conveyed onto a cylinder, and after carding, the cashmere on the cylinder is stripped by a doffer. When the hair on the cylinder is output to the doffer, the cashmere between the doffer and the cylinder will be subjected to a filling force at this time, and the cashmere will also be subjected to the same filling force during the carding process. Since a layer of card clothing is provided on the cylinder, some short fluff will sink to the bottom of the needles under the influence of the filling force, and the wool that sinks to the bottom of the needles will not participate in the carding of the carding structure, that is, "carding wool". As the "carding wool" accumulates, the carding effect of the cashmere will gradually decrease. Therefore, the carding machine needs to be stopped every three cycles to clean the "carding wool" with a carding tool, and it is difficult to continuously card cashmere for a long time. Summary of the Invention

[0003] The purpose of the present invention is to provide an automated continuous operation cashmere carding device to solve the problems mentioned in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: An automated continuous operation cashmere carding device includes a cylinder, a doffer, and a carding structure, and further includes:

[0005] A carding component, which is distributed on the cylinder and the doffer;

[0006] A control component, which is arranged on the cylinder;

[0007] Among them, the carding component includes a first electrostatic generator and a second electrostatic generator. The first electrostatic generator is arranged at the central part of the cylinder, and the second electrostatic generator is located at the central part of the doffer. Both the first electrostatic generator and the second electrostatic generator are installed on the housing part of the carding device. A first conductive head is provided at the end of the first electrostatic generator, and a second conductive head is provided at the end of the second electrostatic generator. A first conductive bar is installed outside the first conductive head. There are also several groups of first electrode plates and second electrode plates. The first electrode plates are equidistantly distributed on the cylinder, the second electrode plates are equidistantly distributed on the doffer, and the outside of the second electrode plates is connected to a conductive ring through a second conductive bar;

[0008] The outer periphery of the cylinder is wrapped with a first elastic card clothing, and the outer periphery of the doffer is wrapped with a second elastic card clothing;

[0009] Among them, the control component includes several groups of wires, the wires are laid on the outer surface of the first elastic card clothing, and further includes an electrostatic sensor and an annular plate. The annular plate is installed on one side of the cylinder, and the electrostatic sensor is installed at the housing part of the carding device. A conductive sheet is connected to the joint of the electrostatic sensor, and several groups of metal sheets are inlaid inside the annular plate.

[0010] Preferably, one end of the wire is connected to the metal sheet.

[0011] Preferably, the conductive sheet is in contact with the metal sheet.

[0012] Preferably, the wire includes a metal wire and an insulating layer. The insulating layer wraps the outer surface of the metal wire, and the wire is located at the bottom between two adjacent groups of comb needles on the surface of the first elastic card clothing.

[0013] Preferably, the insulating layer is in contact with two adjacent groups of comb needles, the metal wire is not in contact with the comb needles, the cross-section of the insulating layer is in a "U" shape, and the opening direction of the insulating layer is the same as the orientation of the tips of the adjacent comb needles.

[0014] Preferably, the first electrode plate is the positive electrode and the second electrode plate is the negative electrode.

[0015] Preferably, the first electrostatic generator is controlled to be energized by the electrical signal transmitted by the electrostatic sensor, and the second electrostatic generator is always in an energized state.

[0016] Preferably, the first conductive bar is in contact with the first electrode plate, and the wire is distributed in a serpentine shape.

[0017] Preferably, the conductive ring is in contact with the second conductive head.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. In the present invention, the static electricity formed by the frictional force generated during the carding of cashmere. Since cashmere loses electrons and forms positive electricity when rubbing against metal, by setting the first electrode plate on the cylinder and the second electrode plate on the doffer, according to the characteristic that the electric field direction is from positive to negative, therefore, a repulsive force will be formed between the cashmere on the first elastic card clothing and the cylinder. At this time, the fluff sinking to the bottom of the needles will be mixed with the outer cashmere and participate in the next carding, avoiding the formation of lappings, and the cashmere can be continuously carded without stopping the machine.

[0020] 2. By arranging a conducting wire on the elastic card clothing 1, the present invention enables it to sense the cashmere that sinks to the bottom of the needle. As the cylinder rotates, the annular plate will drive the metal sheet to rotate. Through the cooperation between the conducting sheet and the metal sheet, the electrostatic sensor can detect whether the cashmere at different positions sinks to the bottom. When the fluff sinks to the bottom after being carded, the electrostatic generator 1 is started to form an electric field to repel the fluff that sinks to the bottom of the needle, preventing the electric field from attracting the cashmere that does not carry static electricity.

[0021] 3. Through the electric field between the electrode plate 1 and the electrode plate 2, the cashmere between the two will shift along the direction of the electric field, making it easier for the doffer to strip the cashmere on the cylinder, and improving the transfer rate of the cashmere from the cylinder to the doffer, thus improving the output efficiency of the cashmere.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1 to 7 shown, the embodiment of the present invention provides an automated continuous operation cashmere carding device, which includes a cylinder 1, a doffer 2 and a carding structure 3, and further includes:

[0032] A needle stripping component, which is distributed on the cylinder 1 and the doffer 2;

[0033] A control component, which is arranged on the cylinder 1;

[0034] Among them, the needle stripping component includes an electrostatic generator 1 4 and an electrostatic generator 2 4a. The electrostatic generator 1 4 is arranged at the central part of the cylinder 1, and the electrostatic generator 2 4a is located at the central part of the doffer 2. Both the electrostatic generator 1 4 and the electrostatic generator 2 4a are installed at the housing part of the carding device. A conductive head 1 5 is arranged at the end of the electrostatic generator 1 4, and a conductive head 2 5a is arranged at the end of the electrostatic generator 2 4a. A first conductive strip 6 is installed outside the conductive head 1 5. There are also several groups of electrode plates 1 7 and electrode plates 2 7a. The electrode plates 1 7 are equidistantly distributed on the cylinder 1, and the electrode plates 2 7a are equidistantly distributed on the doffer 2. The outside of the electrode plates 2 7a is connected to a conductive ring 9 through a second conductive strip 8;

[0035] The outer periphery of the cylinder 1 is wrapped with an elastic card clothing 1 10, and the outer periphery of the doffer 2 is wrapped with an elastic card clothing 2 10a;

[0036] Among them, the control component includes several groups of wires 15, and the wires 15 are laid on the outer surface of the elastic card clothing 1 10. There are also an electrostatic sensor 11 and an annular plate 13. The annular plate 13 is installed on one side of the cylinder 1, and the electrostatic sensor 11 is installed at the housing part of the carding device. A conductive sheet 12 is connected to the joint of the electrostatic sensor 11, and several groups of metal sheets 14 are inlaid inside the annular plate 13.

[0037] Among them, when the cashmere is carded by the carding structure 3, friction will occur between the carding structure 3 and the cashmere. After the cashmere is rubbed, a phenomenon of charge transfer will occur. Since the carding structure 3 is made of metal and the binding ability of metal to electrons is stronger than that of cashmere, the charge of the cashmere will transfer to the carding structure 3. At this time, the cashmere will carry a positive charge. When the filling force generated when the cashmere is carded by the carding structure 3 causes some fluff to sink to the bottom of the needle, the fluff will come into contact with the metal wire 15a at this time. When the metal wire 15a senses static electricity, the static electricity will spread to the position of the metal sheet 14. Since the conductive sheet 12 is in contact with the metal sheet 14, the static electricity sensor 11 will sense the static electricity in this area. When the static electricity sensor 11 receives the static electricity, it will generate an electrical signal to control the start of the first static electricity generator 4, so that electricity can be transmitted to the first conductive bar 6 through the first conductive head 5. At the same time, since the first conductive bar 6 is in contact with the first electrode plate 7, an electric field will be formed between the first electrode plate 7 and the second electrode plate 7a at this time. The direction of the electric field starts from the positive charge and ends at the negative charge. Therefore, the cashmere carrying a positive charge will repel the electrode plate carrying a positive charge. When the cylinder 1 transfers the cashmere to the doffer 2, because they are in a carding relationship, the cashmere will be divided into two parts. One part will remain on the doffer 2 and continue to rotate, that is, return to the load, so that the fluff sinking to the bottom of the needle will be mixed with the cashmere in the returned load under the influence of the electric field, enabling it to participate in the next carding, preventing the formation of carding waste, and enabling the equipment to operate continuously without stopping for cleaning.

[0038] The static electricity formed by the frictional force generated when the cashmere is carded. Since the cashmere loses charge and forms a positive charge when rubbing against the metal, by setting the first electrode plate 7 on the cylinder 1 and the second electrode plate 7a on the doffer 2, according to the characteristic that the direction of the electric field is from positive to negative, when the cashmere passes through the electric field, a repulsive force will be formed between the cashmere on the first elastic card clothing 10 and the cylinder 1. At this time, the fluff sinking to the bottom of the needle will be mixed with the outer cashmere to participate in the next carding, avoiding the formation of carding waste, and the cashmere can be continuously carded without stopping.

[0039] As Figure 4 、 5 shown, one end of the wire 15 is connected to the metal sheet 14.

[0040] Among them, through the cooperation between the wire 15 and the metal sheet 14, the wire 15 will transfer the static electricity to the position of the metal sheet 14 after contacting the cashmere. Through several groups of metal sheets 14 and wires 15, the static electricity in different areas can be sensed and repelled against the fluff sinking to the bottom of the needle.

[0041] As Figure 5 shown, the conductive sheet 12 is in contact with the metal sheet 14.

[0042] Among them, through the cooperation between the conductive sheet 12 and the metal sheet 14, when the cylinder 1 drives the metal sheet 14 to rotate through the annular plate 13, the conductive sheet 12 will sense the metal sheet 14 at different positions, so that the static electricity at different positions can be sensed by the static electricity sensor 11.

[0043] As Figure 7 shown, the wire 15 includes a metal wire 15a and an insulating layer 15b. The insulating layer 15b is wrapped on the outer surface of the metal wire 15a. The wire 15 is located at the bottom between two adjacent groups of comb needles on the surface of the elastic card clothing one 10.

[0044] Among them, by distributing the wire 15 at the bottom of the comb needles, when fluff sinks to the bottom of the needles, when the corresponding metal sheet 14 rotates to the position of the conductive sheet 12, the static electricity will be sensed by the static electricity sensor 11, so that it controls the start of the static electricity generator one 4 through an electrical signal. When the fluff that has sunk to the bottom of the needles moves to the position between the electrode plate one 7 and the electrode plate two 7a, the electric field between the electrode plate one 7 and the electrode plate two 7a will cause the fluff at the bottom to float outwards.

[0045] As Figure 7 shown, the insulating layer 15b contacts two adjacent groups of comb needles, the metal wire 15a does not contact the comb needles, the cross-section of the insulating layer 15b is in a "U" shape, and the opening direction of the insulating layer 15b is the same as the orientation of the tips of the adjacent comb needles.

[0046] Among them, through the design of the insulating layer 15b, it can prevent the comb needles from directly contacting the metal wire 15a. Since the comb needles are made of metal, it can avoid the static electricity directly transferring to the surface of the metal wire 15a when the cashmere does not sink to the bottom. At the same time, because the insulating layer 15b is in a "U" shape, part of the metal wire 15a is exposed outside, enabling it to contact the cashmere at the bottom, which is convenient for static electricity induction.

[0047] As Figure 2 shown, the electrode plate one 7 is the positive electrode, and the electrode plate two 7a is the negative electrode.

[0048] Among them, since the electrode plate one 7 and the electrode plate two 7a are opposite electrodes, when both of them are energized, an electric field will be formed, and the direction of the electric field will point from the positive electrode to the negative electrode. When the cashmere at the bottom moves to the position of the electric field, the cashmere will separate from the bottom part of the comb needles.

[0049] As Figure 1 、 2 shown, the static electricity generator one 4 is controlled to be energized by the electrical signal transmitted by the static electricity sensor 11, and the static electricity generator two 4a is always in an energized state.

[0050] Among them, the start of the first electrostatic generator 4 is controlled by the electrostatic sensor 11. When it senses that the cashmere sinks to the bottom, the first electrostatic generator 4 can be started to form a temporary electric field, and the position of the electric field is located at the position where the doffer 2 strips the cashmere from the cylinder 1, which can reduce the filling force during the stripping of the cashmere. Moreover, the positive charge generated by the frictional force on the cashmere during the carding process. After the electrostatic sensor 11 senses the static electricity, the first electrostatic generator 4 is started, which can prevent the cashmere from being attracted by the static electricity before being rubbed.

[0051] By arranging the wire 15 on the first elastic card clothing 10, it can sense the cashmere sinking to the bottom of the needles. As the cylinder 1 rotates, the annular plate 13 will drive the metal sheet 14 to rotate. Through the cooperation between the conductive sheet 12 and the metal sheet 14, the electrostatic sensor 11 can detect whether the cashmere at different positions sinks to the bottom. When the fluff sinks to the bottom after being carded, the first electrostatic generator 4 is started to form an electric field to repel the sinking fluff.

[0052] Such as Figure 2 shown, the first conductive bar 6 contacts the first electrode plate 7, and the wire 15 is distributed in a serpentine shape.

[0053] Among them, through the design of the wire 15, since the wire 15 is distributed in a serpentine shape, the range of static electricity that can be sensed is increased. Through several groups of wires 15, the wires 15 can be evenly distributed outside the first elastic card clothing 10, and thus the static electricity at different positions can be sensed.

[0054] Such as Figure 3 shown, the conductive ring 9 contacts the second conductive head 5a.

[0055] Among them, through the cooperation between the conductive ring 9 and the second conductive head 5a, the static electricity generated by the second electrostatic generator 4a will be transmitted to the conductive ring 9 through the second conductive head 5a. At the same time, the second electrode plate 7a is powered by the second conductive bar 8. When the first electrode plate 7 is energized, an electric field will be formed between the two.

[0056] Working principle and usage process:

[0057] First, when the cashmere is conveyed to the position of the cylinder 1 and combed by the combing structure 3, friction will occur between the combing structure 3 and the cashmere. After the cashmere is rubbed, charge transfer will occur, and at this time the cashmere will carry a positive charge. When the filling force generated during the combing of the cashmere by the combing structure 3 causes some fluff to sink to the bottom of the needles, the fluff will come into contact with the wire 15a at this time. When the wire 15a senses static electricity, the static electricity will spread to the position of the metal sheet 14. Since the conductive sheet 12 is in contact with the metal sheet 14, the static electricity sensor 11 can sense the static electricity in this area. When the static electricity sensor 11 receives the static electricity, it will generate an electrical signal to control the start of the first static electricity generator 4, so that power can be transmitted to the first conductive strip 6 through the first conductive head 5. At the same time, since the first conductive strip 6 is in contact with the first electrode plate 7, an electric field will be formed between the first electrode plate 7 and the second electrode plate 7a at this time. The direction of the electric field starts from the positive charge and ends at the negative charge. Therefore, when the positively charged cashmere passes through the electric field, it will repel the positively charged electrode plate, so that the fluff sinking to the bottom of the needles will be mixed with the outer cashmere, enabling it to participate in the next combing and preventing the formation of carding waste.
