In these high-precision fields, any tiny static electricity or dust may have a serious impact on product quality. Therefore, the preparation of high-quality anti-static dust-free wipes has become the key.

[0003] However, there are some problems in the preparation of traditional antistatic dust-free wipes. For example, when mixing the fibers, the fibers may be unevenly mixed, which will not only affect the antistatic performance of the wipes, making it unable to effectively prevent static electricity from damaging sensitive electronic components in practical applications, but also seriously affect the production quality of antistatic dust-free wipes; secondly, in the process of packaging and conveying the mixed fibers, the impact force during feeding will inevitably squeeze the fibers, reduce the looseness of the fibers, and thus greatly reduce the production quality of the antistatic dust-free wipes; furthermore, since the fibers may be too light, it is easy to have unclean feeding after mixing, which will not only cause fiber waste and increase production costs, but also affect the ratio between the fibers, reduce the uniformity of fiber mixing, and thus increase the negative impact on the production quality of the antistatic dust-free wipes.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example: See also Figure 1 and Fig. 9 As shown, the purpose of this embodiment is to provide a method for preparing an anti-static dust-free wiping cloth, comprising the following steps: Step 1: Raw material preparation: prepare high-quality polyester fiber and conductive fiber, inspect and screen them to remove impurities and unqualified fibers; select high-quality fibers that meet the requirements by testing the fineness, length, strength and other parameters of the polyester fiber; conduct conductivity and durability tests on the conductive fiber, and calculate the mixing ratio of polyester fiber and conductive fiber to achieve a good balance between antistatic properties and other physical properties.

[0021] Step 2, fiber opening: Use an opening machine to put the polyester fiber into the opening machine for opening treatment to make it fluffy and increase the surface area of ​​the fiber; the speed and strength of the opening machine can be adjusted according to the characteristics of different fibers to ensure that the fiber will not be excessively damaged or entangled during the opening process. During the opening process, add appropriate lubricants or antistatic agents to reduce friction between fibers and reduce the possibility of static electricity generation. At the same time, it can also improve the softness and processability of the fiber.

[0022] Step 3. Combing: Use a carding machine to comb the opened polyester fibers to form a uniform fiber web. The speed, tension, and needle cloth density of the carding machine are optimized and adjusted according to the characteristics of the fiber and product requirements. During the combing process, the thickness, uniformity, and arrangement direction of the fiber web are detected in real time by sensors to ensure that the combing effect meets the requirements. The combed fiber web is cleaned to remove possible impurities and short fibers to improve the purity of the fiber web.

[0023] Step 4: Laying the web: The carded fiber web is laid into a thick web layer through a web laying machine; the speed, tension, laying method and other parameters of the web laying machine are adjusted according to product requirements. During the laying process, pay attention to the edge treatment of the fiber web to ensure that the edges are neat and free of loose fibers, improve the stability of the fiber web, and conduct quality inspections on the laid fiber web, such as thickness consistency and uniformity.

[0024] Step 5: Pre-needling: The laid fiber web is preliminarily reinforced by a pre-needling machine to increase the strength of the web layer. The parameters of the pre-needling machine, such as the needle frequency, depth and density, are adjusted according to the characteristics of the fiber web and product requirements, and the quality of the pre-needling fiber web is tested, such as strength, thickness and uniformity.

[0025] Step 6. Main needling: The mesh layer after pre-needling is reinforced by the main needling machine to form a tight non-woven fabric structure. The needling parameters of the main needling machine can be finely adjusted according to the final performance requirements of the product. During the main needling process, the needling depth and density are controlled to ensure that the fiber web forms a tight non-woven fabric structure. At the same time, care is taken to avoid excessive needling that may cause fiber breakage or damage. The non-woven fabric after the main needling is subjected to quality inspection, such as strength, air permeability, thickness and uniformity.

[0026] Step 7. Antistatic treatment: Use a mixer to mix the conductive fiber with the polyester fiber, and then transport the mixed fiber to the needle punching machine. During the transportation process, ensure that the fiber is loose to avoid compaction or agglomeration of the fiber. Use the needle punching machine to implant the conductive fiber into the non-woven fabric to make it have antistatic properties.

[0027] Step 8. Finishing: Finish the anti-static non-woven fabric, which at least includes cutting, edge sealing, folding and other processing. During the finishing process, pay attention to keeping the non-woven fabric clean and dust-free to avoid pollution.

[0028] Step 9. Packaging: Use environmentally friendly and durable packaging materials to package the prepared anti-static dust-free wipes; during the packaging process, ensure that the product is tightly packaged to prevent dust and impurities from entering.

[0029] Among them, the mixer used in the present method includes an operating table 10 and a pre-storage box 30, and lifting parts 11 are arranged on both sides of the upper surface of the operating table 10, and a shell 20 is arranged between the two lifting parts 11. A protective shell 21 is arranged on the upper surface of the shell 20, and a stirring member 22 is arranged inside the protective shell 21, and the lower part of the stirring member 22 extends to the inside of the shell 20.

[0030] Both sides of the pre-storage box 30 are connected with cover plates 31 through automatic reset hinges, and both sides of the pre-storage box 30 are provided with fixing members 32 capable of stabilizing the position of the cover plates 31 .

[0031] The stirring element 22 is used to intermittently mix the conductive fibers and the polyester fibers. Meanwhile, the stirring element 22 can also disperse the conductive fibers and the polyester fibers and dry the moisture in the conductive fibers and the polyester fibers.

[0032] The lifting member 11 is used to lift the housing 20 to facilitate the placement and removal of the pre-storage box 30. In addition, the lifting member 11 can slow down the speed of the automatic reset hinge to reset the cover plate 31 during the rising process.

[0033] When the mixed conductive fiber and polyester fiber are transported, the fibers need to be kept loose, so the conductive fiber and polyester fiber are pre-stored in the pre-storage box 30. In order to facilitate the pre-storage box 30 to be placed in the housing 20 for use, therefore, according to Figure 1-Figure 3 It can be known that the specific structure of the lifting member 11 is disclosed, and lifting plates 112 are provided on both sides of the side of the shell 20 away from the opening, and hydraulic cylinders 111 are provided on both sides of the upper surface of the operating table 10, and the piston rod of the hydraulic cylinder 111 is fixedly connected to the lower surface of the lifting plate 112.

[0034] The hydraulic cylinder 111 is powered on to make it work, and the lifting plate 112 is moved upward by the pushing work of the piston rod of the hydraulic cylinder 111. At this time, the pre-storage box 30 can be placed under the shell 20, or the pre-storage box 30 can be pulled out from the bottom of the shell 20, and then the shell 20 is moved downward by the work of resetting the piston rod of the hydraulic cylinder 111 to seal the conductive fiber and the polyester fiber, so as to facilitate the mixing of the conductive fiber and the polyester fiber. This not only facilitates the taking and placing operation of the pre-storage box 30 and improves the work efficiency, but also ensures the environmental stability of the conductive fiber and the polyester fiber during the mixing process through the sealing design. The sealing state can prevent external impurities from entering and maintain the purity of the fiber. It also helps to reduce the generation of static electricity and improve the mixing effect and product quality. In addition, the control of the hydraulic cylinder 111 makes the lifting process smooth and reliable, avoids damage to the mixer and the fiber caused by improper operation, and thus prolongs the service life of the mixer.

[0035] In order to improve the quality of the conductive fiber and polyester fiber blend, therefore, according to Figure 1 , Figure 4 and Figure 5 It can be known that the specific structure of the stirring member 22 is disclosed. The stirring member 22 at least includes a mounting block 221. A multi-stage cylinder 222 is arranged inside the protective shell 21. The piston rod of the multi-stage cylinder 222 is provided with a connecting plate 223. A gear rod 224 is arranged on one side of the connecting plate 223. A main tooth 225 that can be meshed with the gear rod 224 is arranged in the middle of the upper surface of the shell 20, and auxiliary teeth 226 are meshed on both sides of the main tooth 225.

[0036] The rotating shaft of the main tooth 225 extends to the inside of the shell 20 and is coaxially connected to the rotating shaft 227. The outer wall of the rotating shaft 227 is provided with a plurality of stirring blades 228. The rotating shaft of the auxiliary tooth 226 extends to the inside of the shell 20 and is coaxially connected to the fan 229.

[0037] The multi-stage cylinder 222 is connected to a power source to make it work. The piston rod of the multi-stage cylinder 222 is pushed and reset to drive the rotating shaft 227 and the fan 229 to rotate, so as to realize the forward, reverse and stop actions of the rotating shaft 227 and the fan 229, thereby forming an intermittent stirring mode, which allows the fibers to have time to settle and redistribute during the stirring process, and helps to improve the uniformity of the mixing. Not only can the conductive fibers and polyester fibers be intermittently mixed, but the fan 229 can also blow away the conductive fibers and polyester fibers and dry the moisture in the conductive fibers and polyester fibers, effectively avoiding the influence of moisture on the fiber mixing effect and product quality, reducing the production links, reducing the production cost, and thus improving the production quality of the anti-static dust-free wiping cloth.

[0038] Considering that the cover plate 31 will hit the stirring blade 228 when sealing the pre-storage box 30, in order not to affect the sealing of the pre-storage box 30, Figure 1 , Figure 6 It can be known that the specific structure of the stirring blade 228 is disclosed, and the stirring blade 228 at least includes a mounting plate 2281, and multiple openings of the mounting plate 2281 are provided with connecting shafts 2282, and a stirring rod 2283 is provided in the middle of the connecting shaft 2282, and automatic return springs 2284 are provided on both sides of the stirring rod 2283, and the other end of the automatic return spring 2284 is fixedly connected to the side of the mounting plate 2281, and the automatic return spring 2284 is sleeved on the outside of the connecting shaft 2282.

[0039] When the piston rod of the hydraulic cylinder 111 moves upward, it drives the shell 20 to move upward. When the cover plate 31 is not blocked by the shell 20, the cover plate 31 is flipped through the automatic return hinge. At this time, the cover plate 31 hits the stirring rod 2283 and deforms the automatic return spring 2284, thereby prompting the stirring rod 2283 to rotate, which can effectively slow down the speed of the cover plate 31. The buffering effect of the automatic return spring 2284 can prevent the fiber from flying due to the movement of the cover plate 31, avoid wasting conductive fiber and polyester fiber, and reduce the risk of material loss. When the cover plate 31 is away from the stirring rod 2283, the stirring rod 2283 will be The rebound force of 84 is used to reset, which is convenient for the next stirring of the conductive fiber and the polyester fiber. It not only ensures the smooth sealing operation of the pre-storage box 30, but also effectively solves the conflict problem between the cover plate 31 and the stirring blade 228, so that the sealing process of the pre-storage box 30 is not disturbed, but also improves the reliability and durability of the mixer, reduces the hard collision between the cover plate 31 and the stirring blade 228, reduces the possibility of damage to the mixer, and extends the service life of the equipment. In addition, it enhances the safety of operation, avoids the potential safety hazards caused by flying fibers, such as respiratory irritation to the operator or pollution to surrounding equipment, and provides a safer working environment for the production process.

[0040] Since the cover plate 31 is connected to the pre-storage box 30 through an automatic reset hinge, in order to facilitate the pre-storage box 30 to be placed under the housing 20, according to Figure 1 , Figure 2 and Figure 6 It can be known that the specific structure of the fixing part 32 is disclosed. The fixing part 32 at least includes a pull plate 321, a buckle plate 322 is arranged on the upper surface of the pull plate 321, a two-way cylinder 323 is arranged inside the buckle plate 322, and the piston rods at both ends of the two-way cylinder 323 are provided with fixing rods 324, and a fixing groove 325 is opened on one side of the cover plate 31.

[0041] When it is necessary to open the cover 31, hold the handle on the upper surface of the cover 31 and flip it outward so that the buckle plate 322 enters the interior of the fixing groove 325. At this time, turn on the two-way cylinder 323, and push the fixing rod 324 into the side of the fixing groove 325 through the piston rods at both ends of the two-way cylinder 323, so that the position of the cover 31 is stabilized. After that, the pre-storage box 30 can be placed under the shell 20.

[0042] When the shell 20 moves downward, the piston rod of the two-way cylinder 323 is reset to make the fixing rod 324 away from the two sides of the fixing groove 325. At this time, the buckle plate 322 is separated from the fixing groove 325 by the resilience of the automatic reset hinge, and at the same time, the cover plate 31 is driven to flip so that one side of the cover plate 31 is tightly attached to the outer wall of the shell 20. In addition, the position of the pre-storage box 30 can be corrected by the resilience of the automatic reset hinge, so that the pre-storage box 30 and the shell 20 form a complete sealed space.

[0043] It not only improves the convenience and efficiency of operation, but also improves the work efficiency of operation, and enhances the sealing effect, prevents the conductive fiber and polyester fiber from being contaminated by external impurities during the mixing process, ensures the quality of the product, and improves the stability of the mixer. The design of the fixing part 32 enables the cover plate 31 to remain stable in both the open and closed states, avoiding safety hazards caused by accidental shaking or external forces. At the same time, it also provides reliability for the normal operation of the mixer, thereby improving the practicality of the mixer.

[0044] Considering that the sealing effect of the connection between the cover plate 31 and the pre-storage box 30 is not good, during the mixing process of the conductive fiber and the polyester fiber, it is inevitable that the conductive fiber and the polyester fiber will fly out from the connection between the cover plate 31 and the pre-storage box 30, causing waste. The proportion of the conductive fiber and the polyester fiber flying out will also affect the quality of the anti-static dust-free wiping cloth production. Therefore, according to Figure 1 and Figure 3 It can be seen that elastic parts 23 are provided on both sides of the openings on both sides of the shell 20. The elastic parts 23 can not only increase the sealing of the connection between the pre-storage box 30 and the shell 20, but also relieve the rebound force of the automatic reset hinge, increase the resistance on the cover 31, and reduce the frequency of splashing of conductive fibers and polyester fibers. At the same time, the stability of the mixer can be further enhanced. During the mixing process, the elastic parts 23 can play a buffering role and reduce the impact of vibrations generated by the operation of the mixer on the sealing of the connection. In addition, good sealing helps to maintain the stability of the mixing environment and ensure the accurate mixing ratio of conductive fibers and polyester fibers, thereby improving the production quality and consistency of anti-static dust-free wiping cloths. It can also reduce the possibility of external impurities entering the mixing area and maintain the purity of the fibers, thereby improving the production quality of anti-static dust-free wiping cloths.

[0045] In summary, the working principle of this scheme is as follows: first, the hydraulic cylinder 111 is powered on to make it work, and the lifting plate 112 is moved upward by the piston rod of the hydraulic cylinder 111 to lift the shell 20. Then, the handle on the upper surface of the cover plate 31 is gripped and turned outward to make the buckle plate 322 enter the inside of the fixed groove 325. At this time, the two-way cylinder 323 is turned on, and the piston rods at both ends of the two-way cylinder 323 are pushed to make the fixing rod 324 enter the side of the fixing groove 325, so that the position of the cover plate 31 is stabilized, and then the conductive fiber and the polyester fiber are put into the pre-storage box 30 according to the proportion. The housing 20 is moved downward by the piston rod reset of the hydraulic cylinder 111 to seal the conductive fiber and the polyester fiber. Then, the fixing rod 324 is moved away from both sides of the fixing groove 325 by the piston rod reset of the bidirectional cylinder 323. At this time, the buckle plate 322 is separated from the fixing groove 325 by the resilience of the automatic reset hinge. At the same time, the cover plate 31 is driven to flip so that one side of the cover plate 31 is tightly fitted to the outer wall of the housing 20. In addition, the position of the pre-storage box 30 is corrected by the resilience of the automatic reset hinge.

[0046] At this time, the multi-stage cylinder 222 is powered on to make it work. The multi-stage cylinder 222 piston rod is pushed and reset to drive the gear rod 224 to move forward and backward, and the gear rod 224, the main gear 225 and the auxiliary gear 226 are meshed and connected to make it rotate, thereby driving the rotating shaft 227 and the fan 229 to rotate, realizing the forward, reverse and stop actions of the rotating shaft 227 and the fan 229, so as to dry, disperse and mix the conductive fibers and polyester fibers.

[0047] After the mixing is completed, the hydraulic cylinder 111 is powered on to make it work. The lifting plate 112 is moved upward by the piston rod of the hydraulic cylinder 111 to lift the shell 20. At the same time, when the cover plate 31 is not blocked by the shell 20, the cover plate 31 is flipped by the automatic return hinge. At this time, the cover plate 31 will hit the stirring rod 2283, and the automatic return spring 2284 will be deformed, thereby prompting the stirring rod 2283 to rotate, so that the cover plate 31 is slowly covered. When the cover plate 31 is away from the stirring rod 2283, the stirring rod 2283 will be reset by the rebound force of the automatic return spring 2284 until the cover plate 31 is completely covered. After that, the pull plate 321 is pulled to move the pre-storage box 30 out from under the shell 20 and transport it to the needling machine, and the use of the mixer can be completed.
