Description

Technical Field

[0001] This utility model relates to the field of yarn-dyed fabric production technology, and in particular to a slurry coating device for yarn-dyed fabric with anti-static function. Background Technology

[0002] Yarn-dyed fabric refers to fabric made by first dyeing the yarn or filaments and then weaving them with the colored yarn, the opposite of the "dyed greige fabric" process where the fabric is woven first and then dyed. Its core characteristic is that the yarn itself carries color; the pattern and color are formed by the interlacing of the yarns after weaving, rather than by post-dyeing. Yarn-dyed fabric is prone to static electricity in frictional and dry environments, which may cause the fabric to attract dust, become entangled in the human body, and even cause sparks in electronic and chemical environments. Ordinary yarn-dyed fabric itself does not have anti-static capabilities and requires a coating of anti-static paste. The conductive components in the paste create a charge conduction path, quickly releasing static charge. At the same time, the paste is adapted to the characteristics of the yarn-dyed fabric, without damaging the original color and feel, and also enhances abrasion resistance, ensuring that the anti-static effect remains stable after multiple washes, thus meeting the functional requirements of industrial protection and precision environments.

[0003] The existing technology announcement number CN208183297U discloses a fabric dye uniform coating device. It consists of a base plate, two support frames with fabric roll rollers and take-up rollers respectively, a support plate directly above the base plate, and the sides of the support plate fixed to the base plate by brackets. Rotating frames are located on both sides of the lower end of the support plate, with the upper end of the rotating frame hinged to the lower end of the support plate. A pressure roller is located at the lower end of the rotating frame. The middle of the rotating frame is connected to the lower end of the support plate via an adjusting hydraulic cylinder. A rotating disk is mounted on the main shaft of a rotating motor, and a push-pull crossbar is located on one side of the end face of the rotating disk. An eccentric pushing protrusion is also located on the end face of the rotating disk. A push-pull rod perpendicular to the lower end of the push-pull crossbar is located on the lower end of the push-pull rod, with fixed rods hinged to both sides of the lower end of the push-pull rod. A spreading roller is located at the lower end of the fixed rod, and the two fixed rods are connected in the middle by a return spring.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: When using an internally guided roller coating system to coat yarn-dyed fabrics with antistatic slurry, the discharge holes on the roller surface are prone to blockage due to the drying of the coating. Antistatic slurry often contains high molecular weight components, which are prone to drying at the discharge holes due to contact with air, temperature changes, etc. Especially during production breaks or shutdowns, residual slurry will quickly solidify and adhere to the hole walls, gradually reducing the hole diameter or even completely blocking it, resulting in uneven slurry output. After some holes are blocked, the coating distribution on the roller surface becomes unbalanced, causing localized excessive thickness and missed coatings on the yarn-dyed fabric, affecting the coating quality. In severe cases, it is necessary to stop the machine for cleaning, reducing production efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the discharge hole on the roller surface is easily blocked by the drying of the coating, resulting in uneven slurry discharge, affecting the coating quality and reducing production efficiency. To this end, we propose a slurry coating device with anti-static function for yarn-dyed fabrics.

[0006] To achieve the above objectives, this application adopts the following technical solution: a paste coating device for antistatic function of yarn-dyed fabric, comprising a worktable: a discharge roller and a take-up roller are respectively provided at both ends of the worktable, a coating roller is provided in the middle of the worktable, a storage box is provided on the top of the coating roller, the storage box is fixedly connected to the worktable, an anti-blocking component is provided on the side of the coating roller near the discharge roller, the anti-blocking component is in contact with the coating roller, a scraper and a drying chamber are provided between the coating roller and the take-up roller, and the drying chamber is located between the scraper and the take-up roller.

[0007] Preferably, the coating roller includes a mounting frame, which is installed on both sides of the center of the workbench. A material cylinder is installed on the mounting frame, and a seepage hole is opened at the bottom of the material cylinder. A roller body is provided on the outer ring of the material cylinder, and the roller body is installed on the material cylinder. A discharge hole is opened on the surface of the roller body. A feeding pipe is installed through the mounting frame at one end of the material cylinder. The material cylinder and the feeding pipe are rotatably installed, and the top of the feeding pipe is connected to the bottom of the storage box.

[0008] Preferably, the anti-blocking component includes a support frame, which is installed on both sides of the middle of the workbench. A cavity is opened in the inner wall of the support frame, and a spring is installed in the cavity. One end of the spring is connected to the inner wall of the cavity, and a recycling box is installed at the other end of the spring. The recycling box is installed in the cavity. A scraper is installed on the side of the recycling box away from the spring, and a return pipe is installed on one side of the recycling box. The return pipe is connected to the middle of one end of the material cylinder.

[0009] Preferably, the return pipe is inclined, and the end of the return pipe connected to the recycling box is higher than the end of the return pipe connected to the material cylinder.

[0010] Preferably, the scraper includes a plate body, one end of which is connected to the recycling box, and the other end of which is connected to a scraper head. A guide groove is formed on the upper surface of the plate body.

[0011] Preferably, the scraper head is conical, with the end of the scraper head connected to the plate (651) being thicker and the end of the scraper head away from the plate (651) being thinner, and the tip of the scraper head being in contact with the roller body.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by adding a scraper to the outside of the roller, real-time cleaning of the discharge holes on the roller surface is achieved. The flexible contact of the brush head can adapt to the curvature of the roller, effectively removing residual paint from the holes, reducing the probability of small hole clogging, ensuring uniform slurry output, reducing the frequency of downtime maintenance due to clogging, maintaining a continuous and stable coating rhythm, reducing the problem of uneven coating thickness caused by fluctuations in paint amount, and improving the consistency and quality stability of the antistatic coating of yarn-dyed fabric.

[0014] In this invention, a recycling box is installed at the bottom of the scraper to collect excess paint removed by the scraper. This excess paint is then returned to the roller via a pipe for reuse, reducing paint waste and lowering production costs. Simultaneously, the return component prevents paint from dripping and contaminating equipment and fabric, reducing subsequent cleaning work and improving the cleanliness of the production environment.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Reference Figures 1-2 As shown, this utility model provides a technical solution: a slurry coating device for antistatic function of yarn-dyed fabric, including: a worktable 1, with a discharge roller 2 and a take-up roller 3 respectively arranged at both ends of the worktable 1, a coating roller 4 arranged in the middle of the worktable 1, a storage box 5 arranged on the top of the coating roller 4, the storage box 5 being fixedly connected to the worktable 1, an anti-blocking component 6 arranged on the side of the coating roller 4 near the discharge roller 2, the anti-blocking component 6 being tightly fitted with the coating roller 4, a scraping plate 7 and a drying chamber 8 arranged between the coating roller 4 and the take-up roller 3, the drying chamber 8 being arranged between the scraping plate 7 and the take-up roller 3.

[0024] Reference Figure 3 As shown in this embodiment: the coating roller 4 includes a mounting frame 41, which is installed on both sides of the middle part of the workbench 1 by screws. A material cylinder 42 is fixedly installed on the two mounting frames 41. The material cylinder 42 has a hollow structure inside. Multiple seepage holes 43 are evenly opened at the bottom of the material cylinder 42. A roller body 44 is nested around the outer ring of the material cylinder 42. The middle part of the roller body 44 is hollow. The roller body 44 is rotatably installed on the material cylinder 42. Multiple discharge holes 45 are evenly opened on the surface of the roller body 44. A feeding pipe 46 is installed through the mounting frame 41 at one end of the material cylinder 42. The material cylinder 42 and the feeding pipe 46 are rotatably installed. The top of the feeding pipe 46 is connected to the bottom of the storage box 5. When the yarn-dyed fabric is wound and moved by the discharge roller 2 and the take-up roller 3, it will drive the roller body 44 to rotate when passing under the coating roller 4, so that the coating leaks out from the discharge holes 45 and is then roller-coated on the surface of the yarn-dyed fabric.

[0025] Reference Figure 4As shown in this embodiment: the anti-blocking component 6 includes a support frame 61, which is installed on both sides of the middle of the workbench 1 by screws. Each of the two support frames 61 has a cavity 62 on its inner wall. A spring 63 is fixedly installed inside the cavity 62. One end of the spring 63 is fixedly connected to the inner wall of the cavity 62, and the other end of the spring 63 is fixedly installed with a recycling box 64. The two springs 63 are respectively installed on the edges of both ends of the recycling box 64. The two ends of the recycling box 64 are movably installed in the cavities 62 on both sides, with the recycling box 64 on the opposite side from the side where the springs 63 are installed. A sluice gate is provided, and a scraper 65 is fixedly installed inside the sluice gate. The scraper 65 is in close contact with the paint roller 4. The spring 63 is in a compressed state and is used to control the contact pressure between the scraper 65 and the paint roller 4. The spring 63 adaptively adjusts to ensure uniform pressure. A return pipe 66 is installed through one side of the recycling box 64. The return pipe 66 is connected to the middle of the end of the material cylinder 42 away from the feeding pipe 46. The return pipe 66 is set at an angle. The end of the return pipe 66 connected to the recycling box 64 is slightly higher than the end of the return pipe 66 connected to the material cylinder 42.

[0026] Reference Figure 5 As shown in this embodiment: the scraper 65 includes a plate 651, one end of which is connected to the outlet of the recycling box 64, and the other end of which is uniformly connected with multiple scraper heads 653 by adhesive. The scraper heads 653 are conical in shape, and the tips of the scraper heads 653 are tightly fitted to the roller body 44. The scraper heads 653 are made of rubber with a hardness range of Shore hardness of 60-80. Rubber with a Shore hardness of 60-80 has both moderate elasticity and wear resistance, which can not only tightly fit the edge of the discharge hole 45 to scrape off residual slurry and prevent clogging, but also reduce wear on the paint roller 4 and ensure stable slurry flow. Multiple guide grooves 652 are uniformly opened on the upper surface of the plate 651. When the scraper head 653 scrapes and cleans the discharge hole 45, the excess paint cleaned by the scraper head 653 can flow into the recycling box 64 along the guide grooves 652 for recycling.

[0027] Working principle: In use, the yarn-dyed fabric is installed on the discharge roller 2 and the take-up roller 3, passing through the bottom of the coating roller 4. By driving the discharge roller 2 and the take-up roller 3, the yarn-dyed fabric is wound up and moved on the worktable 1. The winding and moving of the yarn-dyed fabric drives the coating roller 4 to rotate. At the same time, the slurry in the storage tank 5 flows into the material cylinder 42 through the feeding pipe 46, and leaks into the roller body 44 through the seepage hole 43 at the bottom of the material cylinder 42. As the coating roller 4 rotates, the slurry is evenly leaked out from the discharge hole 45 below, and then roller-coated onto the yarn-dyed fabric. On the fabric surface, the scraper head 653, which is in contact with the surface of the roller body 44, flexibly scrapes out the discharge hole 45, removes the coating residue at the hole opening, reduces the probability of clogging of the discharge hole 45, and ensures uniform slurry output. The excess slurry scraped by the scraper head 653 flows into the recycling box 64 through the guide groove 652 for secondary use, reducing slurry waste. After the roller coating, the yarn-dyed fabric passes through the scraper plate 7, where the excess coating on the surface is scraped off again to avoid uneven roller coating at the front end. Then it is dried in the drying chamber 8 and finally wound up by the take-up roller 3.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
