Description

Technical Field

[0001] This utility model relates to the technical field of negative ion fabric processing, specifically a negative ion powder uniformly spreading device for negative ion fabric processing. Background Technology

[0002] Negative ion fabric is a functional textile material made by adding natural mineral negative ion elements. Its core characteristic is the continuous release of negative ions. The released negative oxygen ions can penetrate the skin or enter the human body through respiration, promoting blood circulation and metabolism, enhancing immunity, relieving fatigue and improving sleep quality.

[0003] Currently, most negative ion fabric processing involves spraying negative ion dust through nozzles. These nozzles are typically fixed inside the device, but the fixed angle of the nozzles cannot be adjusted according to the size of the fabric and the dynamic position of the feed. This makes it impossible to adapt to the undulating structure of the fabric surface, resulting in powder accumulation in raised areas and an excessively thin coating in recessed areas. Utility Model Content

[0004] The purpose of this invention is to provide a device for uniformly distributing negative ion powder in the processing of negative ion fabrics, so as to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a negative ion powder uniformly spreading device for negative ion fabric processing, comprising a coating box, a receiving roller, a scraping blade, and a servo motor. A feeding hood is fitted to the top of the coating box, and a door is hinged to the outside of the coating box. A conveying mechanism is provided on the outside of the coating box, which collects and feeds the fabric. By controlling the rotation speed of the receiving roller, the surface of the fabric is coated. A coating mechanism is provided inside the coating box, which uses an arc-shaped toothed arm to tilt multiple sets of powder nozzles, thereby adjusting the spraying angle of the powder nozzles and controlling the spraying area on the fabric surface.

[0006] As a preferred technical solution, the conveying mechanism includes a receiving roller, a feeding chute, a feeding roller, a high-voltage electrostatic generator, and a storage bin. The receiving roller is installed on one side of the paint box, and the feeding chute is provided through both sides of the paint box. The feeding roller is provided on the other side of the paint box. The high-voltage electrostatic generator is installed on the outside of the storage bin, and the storage bin is located inside the paint box. The storage bin is connected to the output end of the powder nozzle through a conveying pump.

[0007] As a preferred technical solution, the high-voltage electrostatic generator is connected to the inside of the powder nozzle through a discharge electrode, and the high-voltage electrostatic generator operates by negatively charging the negative ion powder through the discharge electrode.

[0008] As a preferred technical solution, the coating mechanism includes a drive shaft, a scraper blade, a gear, a positioning shaft, an arc-shaped toothed arm, a powder nozzle, and a servo motor. The drive shaft is connected to the output end of the servo motor via a coupling. The scraper blade is installed at the inner end of the coating box. Multiple sets of powder nozzles are evenly spaced on the outer side of the arc-shaped toothed arm. The servo motor is installed on the back of the coating box. The positioning shaft is connected through the arc-shaped toothed arm. A gear is meshed at the top of the arc-shaped toothed arm. The servo motor is connected to the other end of the drive shaft via a coupling connected to the output end.

[0009] As a preferred technical solution, the arc-shaped toothed arm is connected to the bearings on both sides of the inner end of the paint box through a through-connected positioning shaft.

[0010] As a preferred technical solution, the positioning shaft meshes with the outer side of the arc-shaped toothed arm via a gear connected by an outer key, and the length of the arc-shaped toothed arm is consistent with that of the feed channel.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes the meshing characteristics of arc-shaped toothed arms and arc-shaped cylindrical gears to allow the nozzle to maintain meshing stability during tilt adjustment. When the arc-shaped tooth structure rotates within a range of ±15°, it can maintain transmission accuracy without recalibration. A single arc-shaped toothed arm can link 4–8 sets of nozzles. Real-time adjustment of the nozzle tilt angle allows the powder spray trajectory to adapt to the fabric surface, and edge accumulation is avoided by adjusting the angle.

[0012] 2. This utility model uses a servo motor to drive an arc-shaped toothed arm through a reduction gear set. The servo motor drives the blades to rotate and stir. During rotation, a centrifugal force field is generated to break up agglomerated particles. High-speed rotation can break up clumps of dust, maintain the fluidization of powder, and reduce the risk of blockage in the powder conveying pipeline. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Figures 1 to 5 As shown, this utility model provides the following technical solution: a negative ion powder uniformly spreading device for negative ion fabric processing, including a coating box 1, a receiving roller 4, a scraping blade 12, and a servo motor 17. A feeding cover 2 is attached to the top of the coating box 1, and a box door 3 is hinged to the outside of the coating box 1. A conveying mechanism 7 is provided on the outside of the coating box 1. The conveying mechanism 7 collects and feeds the fabric. By controlling the rotation speed of the receiving roller 4, the surface of the fabric is coated. A coating mechanism 9 is provided inside the coating box 1. The coating mechanism 9 drives multiple sets of powder nozzles 16 to tilt through an arc-shaped toothed arm 15, thereby adjusting the spraying angle of the powder nozzles 16 and controlling the spraying area on the fabric surface.

[0017] like Figure 1 , Figure 2 and Figure 4 As shown, the conveying mechanism 7 includes a receiving roller 4, a feeding chute 5, a feeding roller 6, a high-voltage electrostatic generator 10, and a storage bin 11. The receiving roller 4 is installed on one side of the paint box 1. The feeding chute 5 is provided through both sides of the paint box 1. The feeding roller 6 is provided on the other side of the paint box 1. The high-voltage electrostatic generator 10 is installed on the outside of the storage bin 11. The storage bin 11 is located inside the paint box 1. The storage bin 11 is connected to the output end of the powder nozzle 16 through a conveying pump. The high-voltage electrostatic generator 10 is connected to the inside of the powder nozzle 16 through a discharge electrode. The high-voltage electrostatic generator 10 operates by negatively charging the negative ion powder through the discharge electrode.

[0018] Among them: the high voltage electrostatic generator 10 outputs a negative high voltage of 60–100kV, which is directly transmitted to the discharge electrode of the powder nozzle 16 through the internal wire. The electrode tip triggers corona discharge, ionizes the air to generate a negative ion cloud, and makes the sprayed powder particles capture electrons and carry a negative charge. The voltage is dynamically adjusted according to the fabric thickness / density, and the voltage is dynamically adjusted according to the fabric thickness and density.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the coating mechanism 9 includes a drive shaft 8, a scraper blade 12, a gear 13, a positioning shaft 14, an arc-shaped toothed arm 15, a powder nozzle 16, and a servo motor 17. The drive shaft 8 is connected to the output end of the servo motor 17 via a coupling. The scraper blade 12 is installed at the inner end of the coating box 1. Multiple sets of powder nozzles 16 are evenly spaced on the outer side of the arc-shaped toothed arm 15. The servo motor 17 is installed on the back of the coating box 1. The positioning shaft 14 is connected through the arc-shaped toothed arm 15. The top end of the arc-shaped toothed arm 15 is meshed with the gear 13. The servo motor 17 is connected to the other end of the drive shaft 8 via a coupling connected to its output end. The arc-shaped toothed arm 15 is connected to the bearings on both sides of the inner end of the coating box 1 via the through-connected positioning shaft 14. The positioning shaft 14 meshes with the outer side of the arc-shaped toothed arm 15 via the gear 13 connected by an outer key. The length of the arc-shaped toothed arm 15 is the same as that of the feed channel 5.

[0020] Among them: the fabric is grounded in advance, and the scraper holder at the top of the scraper blade 12 is connected to a low voltage electrostatic charge of 0.5–1kV during scraping, forming a directional electric field to guide the directional deposition of charged powder. The scraper blade 12 and the electric field work together to guide the directional adsorption of charged powder, enhance the bonding force between powder and fabric, reduce the risk of falling off, and at the same time use the arc-shaped toothed arm 15 to tilt and adjust the powder nozzle 16.

[0021] The working principle of this utility model is as follows: Step 1: The operator first removes the outer fabric of the feeding roller 6 and inserts the fabric into the symmetrical feed trough 5 on the outer side of the paint box 1, so that the scraping blade 12 inside the paint box 1 comes into contact with the surface of the fabric. During the rotation of the receiving roller 4, the scraping blade 12 comes into contact with the fabric. At the same time, the servo motor 17 drives the gear 13 to rotate, and the drive shaft 8 and corresponding blades are used to mix and disperse the material inside the storage box 11. The bottom of the storage box 11 is connected to the Venturi powder pump through the conical discharge port. The Venturi powder pump is used to inject dust into the powder conveying pipe, and the powder is injected into the powder nozzle 16 through the powder conveying pipe. Step 2: During processing, the servo motor 17 is turned on, driving the drive shaft 8 to rotate. The drive shaft 8 then drives the gear 13 to rotate, causing the gear 13 to mesh with the lower arc-shaped gear arm 15. This allows the powder nozzle 16 to maintain meshing stability during tilt adjustment. The positioning shaft 14 is used to connect to the outer side of the arc-shaped gear arm 15, positioning the arc-shaped gear arm 15 and ensuring the powder nozzle 16 maintains meshing stability during tilt adjustment. During meshing, the fabric is sprayed in different directions. Step 3: The high-voltage electrostatic generator 10 outputs a negative high voltage of 60-100kV, which is directly transmitted to the discharge electrode (needle-shaped or metal guide tube) of the powder nozzle 16 through internal wires. The tip of the electrode triggers corona discharge, ionizes the air to generate a negative ion cloud, and causes the sprayed powder particles to capture electrons and become negatively charged. The fabric needs to be grounded through a metal guide roller or conductive plate to form a positive electrode, which forms a closed electric field circuit with the negative high voltage electrode of the powder nozzle 16 to ensure that the electric field force effectively adsorbs the powder. The negatively charged powder flies along the electric field line to the grounded fabric under the drive of the electric field force. Under the dual action of electrostatic force and airflow, it forms an adsorption effect around the fabric fibers, allowing the powder to penetrate into the pores of the fabric. Step 4: The fabric is wound up by the take-up roller 4, which displaces the fabric. At the same time, the flattening blade 12 contacts the surface of the fabric to evenly compact the powder into the gaps between the fabric fibers, achieving micron-level thickness consistency and avoiding sagging or orange peel effect. The fabric is then wound up again by the take-up roller 4 to complete the processing of the negative ion fabric. The powder conveying pipe is made of antistatic material to reduce the risk of clogging.
