Description

Technical Field

[0001] The invention relates to the technical field of environmental protection, in particular to a device for preparing air filter materials. Background Art

[0002] Textile technology refers to the process and technology of processing fibers or fiber aggregates into yarns, fabrics or related products. It covers multiple links such as the selection of fiber raw materials, spinning, weaving, printing and dyeing, and finishing. It is the core of the modern textile industry. Textile fabrics have become one of the most important materials for air filtration, and textile technology provides important support for filtration materials.

[0003] The manufacture of air filter materials usually involves fiber mixing, drawing and weaving processes. In view of its high requirements for cleanliness, the working environment needs to strictly control dust and particulate matter. However, during the rapid weaving process of the fiber line, friction between the fibers will inevitably occur, thereby generating a large amount of dust. Although the loom is equipped with a dust removal device, the fiber line rubs rapidly during the weaving process, generating a large number of positive and negative electrons. These charges make the dust particles also carry different charges. According to the principle of mutual attraction between charges, there will be a strong attraction between the dust particles and the fiber line. The distance between the dust and the dust removal device is relatively far, so a large amount of dust will be tightly adsorbed on the surface of the finished filter cloth. The charge effect makes it difficult to effectively remove the dust. The dust not only reduces the air permeability, but also may clog the filter holes, affect the filtration efficiency, and even damage the filter cloth, shortening its life. Summary of the invention

[0004] The purpose of the present invention is to provide an air filter material preparation device to solve the problem proposed in the above background technology that during the fiber thread weaving process, dust and positive and negative charges are generated due to friction, causing the dust to also carry corresponding charges and be adsorbed on the surface of the filter cloth, resulting in reduced quality and service life of the filter cloth.

[0005] To achieve the above object, the present invention provides the following technical solution: an air filter material preparation device, comprising: The main body of the braiding machine serves as the overall mounting bracket and completes the braiding work; The pay-off assembly is installed on the top of the braiding machine body and is used to continuously provide fiber line raw materials. After the motor is started, it drives the pay-off roller to rotate, providing the braiding machine body with the raw materials required for processing, and drives the pulley and the connecting belt to move through the pay-off roller to provide power for the spiral conveying rod in the dust removal assembly, thereby reducing the power source of the device and achieving the purpose of reducing costs and facilitating maintenance.

[0006] The power generation component is installed between the inner surface walls of the main body of the braiding machine, and is used to continuously drive the relevant components to move, so that they generate a large amount of positive charge through friction and ionization, and transmit the positive charge to the fiber line, so that the dust generated by the fiber line during the weaving process also carries a positive charge. Since there is a repulsive force between charges of the same kind, the dust is kept away from the fiber line, making it easier for external devices to absorb it. After the second motor is started, the conductive roller immediately drives the fiber line to move forward. At the same time, the power transmission belt drives the plastic roller to rotate. The friction between the two causes the plastic roller to carry a negative charge, and the contact surface of the power transmission belt is correspondingly charged with a positive charge. The negative charge on the surface of the plastic roller repels the metal below. The electrons in the brush are transferred to one end of the metal brush. As the electrons accumulate, a positive charge zone begins to form in the area of ​​the metal brush close to the plastic roller. When the positive charge accumulates to a certain level, it will ionize the molecules in the air, causing the electrons in the molecules to be attracted to the surface of the metal brush, while the positive ions are attracted by the negatively charged plastic roller and attached to the surface of the power transmission belt, thereby further increasing the positive charge of the power transmission belt. Subsequently, the power transmission belt transfers the positive charge to the surface of the conductive roller through its movement, so that the conductive roller and the fiber line on it are positively charged together. The dust generated by friction also carries a positive charge, so they are effectively separated from the fiber line.

[0007] A conductive component is installed inside the braiding machine body and connected to the power generation component to conduct the generated negative charge to the ground; The dust removal component is installed on the frame surface of the braiding machine body and is used to quickly remove the dust generated by friction during the braiding process to prevent the dust from being adsorbed on the surface of the fiber line.

[0008] Preferably, the pay-off assembly comprises: A dust cover, a pay-off roller and a motor 1, wherein the motor 1 is installed on one side of the outer wall of the dust cover and is used to provide power. The pay-off roller is fixedly installed at the output end of the motor 1 and continuously pays out the fiber line by rotation. The outer wall of the pay-off roller passes through the interior of the dust cover. The outer wall of the pay-off roller is sleeved with a pulley 1, and the outer wall of the pulley 1 is movably sleeved with a connecting belt to drive other components to rotate synchronously. The dust cover prevents external dust and particulate matter from accumulating on the surface of the pay-off roller and the fiber line, thereby improving the quality of the final product. After the motor 1 is started, it drives the pay-off roller to rotate and pay out the fiber line. At this time, the pay-off roller drives the connecting belt to move through the pulley 1, driving other components to rotate synchronously. One power source can drive multiple components to rotate, thereby reducing the installation and procurement cost of the device, and simplifying the overall structure of the braiding machine, making it easier to maintain.

[0009] Preferably, the power generation component comprises: Motor 2, conductive roller and power transmission belt, the conductive roller is fixedly installed at the output end of motor 2, the power transmission belt is movably sleeved on the outer wall of the conductive roller, and is used to continuously transmit the generated positive charge to the outer surface of the conductive roller, and a plastic roller is sleeved inside the bottom end of the power transmission belt, and the plastic roller and the power transmission belt rub against each other and carry positive and negative charges respectively. The device adopts part of the structure and principle of the Van Draaf generator. When motor 2 is started, the conductive roller starts to rotate, driving the power transmission belt to move and rub against the plastic roller below. At this time, the electrons on the power transmission belt will gather on the surface of the plastic roller, so that the surface of the plastic roller has a negative charge, and the contact surface between the power transmission belt and the plastic roller generates a positive charge, and the positive charge is transported to one end of the top conductive roller through movement, and the positive charge will be evenly distributed on the outer wall of the conductive roller. Since the surface of the conductive roller is wrapped with fiber lines, the fiber lines are transported forward by rotation. Therefore, the positive charge on the surface of the conductive roller will be evenly transferred to the surface of the fiber lines in contact with it, so that the dust generated by the fiber lines during the weaving process is synchronously positively charged, and the dust is conveniently absorbed with the help of the mutual repulsion of the charges.

[0010] Preferably, a protective cover is provided on the movable sleeve of the outer wall of the conductive roller to prevent the external environment from affecting the generation and transfer of electric charges. The left end of the protective cover is sealed and connected to the frame surface of the braiding machine body. One side of the outer wall of the motor 2 is fixedly installed on one side of the outer wall of the braiding machine body. The motor 2 provides a power source for friction. The protective cover is used to isolate the internal plastic roller, the power transmission belt and the left side of the conductive roller from the outside world to prevent external pollutants from being adsorbed on the surface due to the action of electric charges, affecting the electrification effect and reducing the service life of the device.

[0011] Preferably, a rotating shaft 1 is inserted and connected inside the plastic roller, and the left end of the rotating shaft 1 passes through the frame surface of the braiding machine body. A metal brush is passed through and connected on the surface of the braiding machine body. The metal brush can extract negative charges and further strengthen the positive charge on the surface of the power transmission belt by ionizing the air. After the plastic roller generates negative charges due to friction, it will repel electrons on the surface of the metal brush. At this time, the electrons will be transferred to the other end of the metal brush, so that the other end has a negative charge. At the same time, the metal brush begins to accumulate positive charges near the plastic roller. When the positive charge accumulates to a certain extent, it begins to ionize molecules in the air and transfer electrons in the molecules to the surface of the metal brush. The positive ions will be adsorbed to the surface of the power transmission belt by the negatively charged plastic roller, thereby strengthening the positive charge on the surface of the power transmission belt.

[0012] Preferably, the conductive component comprises: Conductor 1, positive charge neutralization roller and conductor 2, conductor 1 is located on one side of the metal brush to facilitate the extraction of negative charge on the metal brush, conductor 2 is installed on the right side of conductor 1, the outer wall of conductor 2 is connected with the positive charge neutralization roller, the positive charge neutralization roller neutralizes the positive charge remaining on the fiber surface through the negative charge transported by conductor 2, the outer wall of conductor 2 penetrates the frame surface of the braiding machine body, the outer wall of conductor 1 is connected with the insulating sleeve 1, the outer wall of conductor 2 is connected with the insulating sleeve 2 to prevent workers from being injured by electricity, and the negative electricity generated at one end of the metal brush can be passed through The negative charge is transported to the surface of conductor two through conductor one, and conductor two transports part of the negative charge to the positive neutralization roller on the outer wall. Since the woven filter material is wound around the positive neutralization roller, the negative charge on the surface of the positive neutralization roller can neutralize the positive charge remaining on the surface of the filter material, reducing the possibility of residual charge attracting dust and causing fire. Insulation sleeve one and insulation sleeve two can prevent the conductor from being directly exposed to the outside, causing workers to work normally due to static electricity. The bottom of conductor two is in contact with the ground, which effectively conducts excess negative charge into the ground, prevents electric shock and sparks, and reduces safety hazards caused by static electricity.

[0013] Preferably, the dust removal assembly comprises: Pulley 2, a spiral conveying rod and a mounting shell, the outer wall of the spiral conveying rod is sleeved with pulley 2, the spiral conveying rod discharges the collected dust by rotation, the outer wall of the pulley 2 is movably sleeved with a connecting belt, the outer wall of the spiral conveying rod is inserted and connected to the surface of the braiding machine body, the right side of the mounting shell is installed on one side of the outer wall of the braiding machine body, the pulley 1, the connecting belt and the pulley 2 constitute a power transmission mechanism, which drives the spiral conveying rod to rotate continuously to discharge the collected dust, reduce the workload of manual cleaning, reduce the downtime of the braiding machine, and ensure work efficiency.

[0014] Preferably, an outer wall of the mounting shell is provided with a movable hole, the outer wall of the spiral conveying rod is movably inserted into the movable hole, an outer shell is fixedly mounted on one side of the outer wall of the mounting shell, an input end of the outer shell is fixedly connected to a group of suction heads, the suction heads are close to the weaving of the fiber lines, so as to further improve the dust removal effect, and the negative pressure generated by the suction heads causes the dust that repel each other due to the positive charge to be uniformly sucked into the inner part of the shell, so as to prevent the dust from continuing to adhere to the filter material and the surface of the device.

[0015] Preferably, a group of mounting holes are provided at the top of the shell, and a group of fans are fixedly inserted into the inner surface walls of one group of the mounting holes. The negative pressure generated by the fans sucks dust into the shell, and a filter is fixedly inserted into the inner surface wall of the shell. The filter prevents dust from leaking from the shell. A power supply is provided on one side of the outer wall of the shell, and a metal plate is provided on one side of the inner wall of the shell. The metal plate will have a negative charge when energized, thereby attracting dust with positive charge to approach. The fan can exhaust the air inside the shell, and at this time, negative pressure is formed inside the shell, so that outside air enters the shell through the suction head. The filter can prevent dust inside the shell from leaking to the outside, thereby reducing the dust removal effect of the device. The power supply and the metal plate are connected by a wire, and the power supply can transmit current to the metal plate, so that the metal plate has a negative charge, and the dust with positive charge is adsorbed on the surface of the metal plate and neutralizes the positive charge of the dust, thereby preventing the dust from being unable to settle due to the repulsive effect of the charge, thereby causing difficulties for the work of the spiral conveying rod.

[0016] Preferably, two ear blocks are fixedly installed on the top of the braiding machine body, and a conveying roller is movably inserted between the inner surface walls of the two ear blocks. The conveying roller can adjust the moving direction of the woven fabric. The woven filter material will be wound around the surface of the conveying roller, and the forward direction will be adjusted by the conveying roller to avoid contact between the filter material and other components, thereby reducing the risk of damage caused by friction or scratches.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1.

With the help of friction and ionization, the surface of the conductive roller is charged with positive charge, and the positive charge is transferred to the fiber line, ensuring that the fiber line and the dust generated in the weaving process are given positive charge. Due to the principle that like charges repel each other, a repulsive force will be generated between the dust and the fiber line, preventing the dust from clinging to the surface of the fiber line, improving the dust removal effect of the filter material during weaving, and thus ensuring that the filtering performance of the material is not affected, effectively extending the service life of the material, and the negative charge generated will neutralize the positive charge remaining on the surface of the woven product, preventing the positive charge from attracting dust particles in the air and causing fire or explosion. The remaining charge is introduced into the ground, reducing the risk of charge accumulation.

[0018] 2. In the present invention, after the fan is started, the dust can be sucked into the inside with the help of the suction head, and then the metal plate is energized to generate negative charge, which can not only attract dust with positive charge, but also neutralize the charge in the dust, so that it can be smoothly settled in the middle of the shell, reducing the possibility of dust leakage and diffusion, and further improving the dust removal effect of the device. The spiral conveying rod can automatically discharge the dust by rotating, which not only reduces the time and cost of manual cleaning, but also reduces the downtime of the braiding machine and ensures the braiding efficiency.

[0019] 3. In the present invention, the motor 1 not only drives the pay-off roller to rotate, but also drives the spiral conveying rod to rotate through the linkage effect of the pulley 1, the connecting belt and the pulley 2.

After the motor 22 is started, it drives the pay-off roller 21 to rotate, providing the braiding machine body 1 with the raw materials required for processing, and drives the pulley 23 and the connecting belt 24 to move through the pay-off roller 21, providing power for the spiral conveying rod 53 in the dust removal assembly 5, thereby reducing the power source of the device and achieving the purpose of reducing costs and facilitating maintenance.

[0024] The power generation component 3 is installed between the inner surface walls of the braiding machine body 1, and is used to continuously drive the relevant components to move, so that a large amount of positive charges are generated by friction and ionization, and the positive charges are transmitted to the fiber line, so that the dust generated by the fiber line during the weaving process also carries positive charges. Since there is a repulsive force between charges of the same kind, the dust is kept away from the fiber line, which is convenient for external devices to absorb it. After the motor 2 31 is started, the conductive roller 33 immediately drives the fiber line to move forward. At the same time, the power transmission belt 34 drives the plastic roller 36 to rotate. The friction between the two causes the plastic roller 36 to carry a negative charge, and the contact surface of the power transmission belt 34 is correspondingly positively charged. The negative charge on the surface of the plastic roller 36 repels the metal brush 37 below. The electrons are transferred to one end of the metal brush 37. As the electrons accumulate, a positive charge area begins to form in the area of ​​the metal brush 37 close to the plastic roller 36. When the positive charge accumulates to a certain level, it ionizes the molecules in the air, causing the electrons in the molecules to be attracted to the surface of the metal brush 37, while the positive ions are attracted by the negatively charged plastic roller 36 and attached to the surface of the power transmission belt 34, thereby further increasing the positive charge of the power transmission belt 34. Subsequently, the power transmission belt 34 transfers the positive charge to the surface of the conductive roller 33 through its movement, so that the conductive roller 33 and the fiber line thereon are positively charged together. The dust generated by friction also carries a positive charge, so they are effectively separated from the fiber line.

[0027] according to Figure 4 , Figure 6 and Fig. 9 As shown, the power generation component 3 includes: Motor 2 31, conductive roller 33 and power transmission belt 34, the conductive roller 33 is fixedly installed at the output end of motor 2 31, the power transmission belt 34 is movably sleeved on the outer wall of the conductive roller 33, and is used to continuously transmit the generated positive charge to the outer surface of the conductive roller 33, and a plastic roller 36 is sleeved inside the bottom of the power transmission belt 34, and the plastic roller 36 and the power transmission belt 34 rub against each other and carry positive and negative charges respectively. The device adopts part of the structure and principle of the Van Draaf generator. When motor 2 31 is started, the conductive roller 33 starts to rotate, driving the power transmission belt 34 to move and rub against the plastic roller 36 below. At this time, the power transmission belt 3 The electrons on 4 will gather on the surface of the plastic roller 36, so that the surface of the plastic roller 36 has a negative charge, and the contact surface between the power transmission belt 34 and the plastic roller 36 generates a positive charge, and the positive charge is transported to one end of the top conductive roller 33 through movement, and the positive charge is evenly distributed on the outer wall of the conductive roller 33. Since the fiber line is wound around the surface of the conductive roller 33 and the fiber line is transported forward by rotation, the positive charge on the surface of the conductive roller 33 will be evenly transferred to the surface of the fiber line in contact with it, so that the dust generated by the fiber line during the weaving process is synchronously positively charged, and the dust is easily absorbed by the mutual repulsion of the charges.

The protective cover 32 is used to isolate the internal plastic roller 36, the power transmission belt 34 and the left side of the conductive roller 33 from the outside world to prevent external pollutants from being adsorbed on its surface due to the action of the charge, affecting the electrification effect and reducing the service life of the device.

[0029] according to Figure 2 , Figure 3 , Figure 4 , Figure 6 and Fig. 9 As shown, the interior of the plastic roller 36 is connected with a rotating shaft 35, and the left end of the rotating shaft 35 passes through the surface of the frame of the braiding machine body 1. A metal brush 37 is passed through the surface of the braiding machine body 1. The metal brush 37 can extract the negative charge and further strengthen the positive charge on the surface of the power transmission belt 34 by ionizing the air. After the plastic roller 36 generates negative charge by friction, it will repel the electrons on the surface of the metal brush 37. At this time, the electrons will be transferred to the other end of the metal brush 37, so that the other end has a negative charge. At the same time, the metal brush 37 begins to accumulate positive charge near the plastic roller 36. When the positive charge accumulates to a certain extent, it begins to ionize the molecules in the air and transfer the electrons in the molecules to the surface of the metal brush 37. The positive ions will be adsorbed by the negatively charged plastic roller 36 to the surface of the power transmission belt 34, thereby strengthening the positive charge on the surface of the power transmission belt 34.

The negative charge can be transported to the surface of conductor two 43 through conductor one 40, and conductor two 43 transports part of the negative charge to the positive neutralization roller 42 on the outer wall. Since the woven filter material is wound around the positive neutralization roller 42, the negative charge on the surface of the positive neutralization roller 42 can neutralize the positive charge remaining on the surface of the filter material, reducing the possibility of residual charge attracting dust and causing fire. Insulation sleeve one 41 and insulation sleeve two 44 can prevent the conductor from being directly exposed to the outside, causing workers to work normally due to static electricity. The bottom of conductor two 43 is in contact with the ground, which effectively guides excess negative charge into the ground, prevents electric shock and sparks, and reduces safety hazards caused by static electricity.

The power supply 59 is connected to the metal plate 591 by a wire. The power supply 59 can transmit current to the metal plate 591, so that the metal plate 591 has a negative charge. The dust with positive charge is then adsorbed on the surface of the metal plate 591 and the positive charge of the dust is neutralized, thereby preventing the dust from being unable to settle due to the repulsive effect of the charge, thereby causing difficulties for the work of the spiral conveying rod 53.
