Description

Technical Field

[0001] This utility model relates to the field of flexible fabric coating technology, specifically a coating device for flexible fabrics. Background Technology

[0002] Flexible fabrics refer to fabrics or composite materials with high softness, extensibility, and foldability. Common types include knitted fabrics, elastic fibers, microfiber fabrics, and silicone-coated fabrics. They are characterized by their sensitive response to external forces such as bending and stretching, making them suitable for scenarios that require conforming to curved surfaces or dynamic use. This type of fabric is mainly used in fields such as sports, medicine, and the electronics industry. In the production process of flexible fabrics, coating pastes are often used to coat the surface of the fabric to improve its overall performance and user experience. Therefore, corresponding coating devices for flexible fabrics are used.

[0003] Existing coating devices for flexible fabrics include structures such as an unwinding mechanism, a winding mechanism, and a coating machine. The unwinding mechanism transports the flexible fabric into the coating machine, where a scraper or coating roller applies the coating. Finally, the winding mechanism collects the coated fabric. However, because the coating slurry has some fluidity after heating, and the fabric needs to maintain a certain tension during transport, uneven tension may cause the coating to thicken at the fabric edges, resulting in uneven coating on the fabric surface and affecting the coating quality of the flexible fabric. Utility Model Content

[0004] The purpose of this invention is to provide a coating device for flexible fabrics, in order to solve the problem mentioned in the background art that, due to the partial fluidity of the coating slurry after heating, and the need to maintain a certain tension during the conveying process, uneven tension of the fabric may lead to thickening of the coating at the edge of the fabric, resulting in uneven coating on the fabric surface and affecting the coating processing quality of flexible fabrics.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating device for flexible fabrics, the coating device being positioned above a support base, comprising a coating machine and a scraping section. The coating machine is positioned above the support base, and the scraping section is positioned outside the coating machine. The scraping section includes a mounting frame positioned outside the coating machine. A bidirectional ball screw is rotatably connected to the inner wall of the mounting frame. Two sets of adjusting blocks are oppositely sleeved on the outer side of the bidirectional ball screw. A horizontal plate is fixedly connected to one end of each adjusting block away from the bidirectional ball screw. An adjusting scraping component is slidably connected to the inner side of the horizontal plate. A rolling support component is positioned below the adjusting scraping component. A servo motor is fixedly mounted on the side of the mounting frame away from the bidirectional ball screw. Activating the servo motor drives the bidirectional ball screw to rotate, thereby causing the two sets of adjusting blocks to move closer to or further away from each other.

[0006] By adopting the above technical solution, a scraping structure adapted to fabrics of different thicknesses and sizes is formed.

[0007] Preferably, the rolling support includes a base plate located below the horizontal plate, a roller is rotatably connected to the inner side wall of the base plate, and the base plate is fixedly connected to the end of another set of adjusting sleeve blocks.

[0008] By adopting the above technical solution, the bottom surface of the fabric is supported, while coordinating with the fabric conveying process.

[0009] Preferably, the adjusting scraping component includes a scraping plate slidably connected to the inner side of the horizontal plate, a one-way threaded rod rotatably connected to the center position of the top surface of the scraping plate, a fixing block sleeved on the outer side of the one-way threaded rod, and the one-way threaded rod being threadedly connected to the inner side of the fixing block.

[0010] By adopting the above technical solution, when the top of the one-way threaded rod is held and rotated continuously, the fixed sleeve block is pushed upward to release the fixed state of the scraping plate.

[0011] Preferably, the mounting frame has two sets of mounting cavities inside, which are symmetrically distributed on the vertical central axis of the mounting frame. A support vertical plate is fixedly connected to the inner wall of one set of mounting cavities, and a bidirectional ball screw is provided inside the other set of mounting cavities. The bottom end of the bidirectional ball screw is rotatably connected to the bottom surface inside the mounting cavity.

[0012] By adopting the above technical solution, it is convenient to install transmission and support structures such as bidirectional ball screws and support vertical plates.

[0013] Preferably, two sets of sliding sleeves are slidably sleeved on the outer side of the supporting vertical plate. One set of sliding sleeves is fixedly connected to the end of the horizontal plate away from the adjusting sleeve, and the other set of sliding sleeves is fixedly connected to the end of the bottom plate away from the adjusting sleeve.

[0014] By adopting the above technical solution, support is provided for the end of the horizontal plate that is away from the adjusting sleeve.

[0015] Preferably, both sets of the adjusting sleeves have threaded groove scale plates inside, and the bidirectional ball screw passes through the interior of the two sets of adjusting sleeves in sequence and is threadedly connected to the inner side of the threaded groove scale plates.

[0016] By adopting the above technical solution, the two sets of adjusting blocks are moved closer to or further apart.

[0017] Preferably, the inside of the horizontal plate is provided with a moving groove, which communicates with the top surface of the horizontal plate. The top end of the one-way threaded rod passes through the inside of the moving groove and extends to the outside of the horizontal plate. A fixing sleeve is fixedly connected to the outer side wall of the mounting bracket.

[0018] By adopting the above technical solution, the scraper plate after its position has been adjusted is fixed.

[0019] Preferably, the winding mechanism is located on the side of the coating machine away from the scraping section, and the bottom end of the winding mechanism is fixedly connected to the top surface of the support frame. The winding mechanism is used to wind up the flexible fabric. The unwinding mechanism is located on the side of the coating machine away from the scraping section, and the bottom end of the unwinding mechanism is fixedly connected to the top surface of the support frame. The unwinding mechanism is used to unwind the flexible fabric.

[0020] By adopting the above technical solution, the fabric is sequentially unrolled and rolled up.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) Start the servo motor through the control panel. The output end of the servo motor drives the bidirectional ball screw to rotate, pushing the two sets of adjustment blocks to move closer or further apart. The adjustment blocks drive the horizontal plate and the roller to move closer or further apart until the distance between the scraping plate and the roller is adapted to the fabric thickness. When the flexible fabric passes through the inside of the scraping section, the scraping plate scrapes the edge of the fabric. At the same time, when the two sets of scraping plates are pushed to move laterally, the distance between the two sets of scraping plates can be adjusted, thereby forming a scraping structure on the outside of the coating machine that is adapted to fabrics of different thicknesses and sizes. This reduces the problem of uneven coating on the fabric surface and has multiple advantages of being adjustable according to the fabric thickness and width, thus improving the adaptability of the scraping structure to various fabrics.

[0023] (2) By setting a one-way threaded rod, a moving groove and a fixed sleeve, when the top of the one-way threaded rod is held and rotated continuously, the fixed sleeve is pushed upward to release the fixed state of the scraping plate, which makes it easy to readjust the distance between the two sets of scraping plates. After holding the one-way threaded rod and rotating it in the opposite direction, the fixed sleeve is pushed downward vertically until it is in close contact with the top surface of the horizontal plate, thus completing the fixing of the scraping plate. This makes it easier to fix the scraping plate after the position is adjusted, and improves the stability of the scraping plate during operation. Attached Figure Description

[0030] 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.

[0031] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0032] Example 1

[0033] Please see Figure 1-5This embodiment provides a coating device technical solution for flexible fabrics: a coating device for flexible fabrics, which is set above the support base 1, includes a coating machine 2 and a scraping part 3. All equipment in the coating device is connected to an external power source through power lines. The coating device is also connected to a control panel, which is connected to the control panel through a data line. The coating machine 2 is set above the support base 1, and the winding mechanism 4 is set on the side of the scraping part 3 away from the coating machine 2.

[0034] The bottom end of the winding mechanism 4 is bolted to the top surface of the support frame 1. The winding mechanism 4 is used to wind up the flexible fabric. The unwinding mechanism 5 is located on the side of the coating machine 2 away from the scraping section 3. The bottom end of the unwinding mechanism 5 is bolted to the top surface of the support frame 1. The unwinding mechanism 5 is used to unwind the flexible fabric. Both the winding mechanism 4 and the unwinding mechanism 5 are equipped with matching drive motors to drive the winding roller or the unwinding roller to rotate. The bottom end of the coating machine 2 is bolted to the bottom surface of the support frame 1. The coating machine 2 includes a coating roller, a slit mold, a constant temperature system, an electric push rod, a back pressure chamber, and a feeding system. The constant temperature system is used to control the temperature of the coating slurry. The feeding system stably delivers the slurry to the coating head and the coating roller or scraper to ensure constant flow and pressure. The above is the prior art and will not be described in detail below.

[0035] The flexible fabric that needs to be coated is continuously released through the unwinding mechanism 5. The unwinding mechanism 5 has functions such as tension control and conveying. The unwinding mechanism 5 conveys the flexible fabric to the inside of the coating machine 2, while ensuring that the fabric is flat and without deviation. The coating machine 2 performs coating work by contacting the fabric with the coating roller. The coating machine 2 applies the coating paste to the surface of the fabric for coating. After coating, the fabric is uniformly wound up by the winding mechanism 4.

[0036] Example 2

[0037] Please see Figure 1-5 The scraping part 3 is located on the outside of the coating machine 2. The scraping part 3 includes a mounting bracket 301 located on the outside of the coating machine 2. A bidirectional ball screw 302 is rotatably connected to the inner wall of the mounting bracket 301 via a bearing. The surface of the bidirectional ball screw 302 is provided with two sets of opposing threaded surfaces.

[0038] The mounting bracket 301 has two sets of mounting cavities 309 inside. The two sets of mounting cavities 309 are symmetrically distributed on the vertical central axis of the mounting bracket 301. The two sets of mounting cavities 309 are respectively located at both ends of the horizontal plate 304. The adjusting sleeve block 303 and the bidirectional ball screw 302 are both located inside the mounting cavity 309. The bottom end of the bidirectional ball screw 302 is rotatably connected to the bottom surface inside the mounting cavity 309 through a bearing.

[0039] The mounting bracket 301 is bolted to the side away from the bidirectional ball screw 302, where a servo motor 308 is connected. The driver inside the servo motor 308 uses a digital signal processor as the control core to implement complex control algorithms, including digital, networked, and intelligent control. The driver rectifies the input power supply through a three-phase full-bridge rectifier circuit to obtain DC power, which is then driven by a three-phase sinusoidal "PWM" voltage inverter. The above is the existing technology and will not be elaborated further below. At the same time, when selecting the model, its power and speed should be selected to suit the needs of the device to ensure that the object to be driven is driven.

[0040] The output end of the servo motor 308 extends into the interior of the mounting cavity 309 and is connected to the top of the bidirectional ball screw 302 via a coupling. Therefore, when the servo motor 308 starts, it drives the bidirectional ball screw 302 to rotate continuously. Two sets of adjusting sleeves 303 are respectively sleeved on the outer side of the bidirectional ball screw 302. Both sets of adjusting sleeves 303 have threaded groove scale plates 312 inside.

[0041] The bidirectional ball screw 302 passes through the interior of two sets of adjusting sleeves 303 in sequence and is threadedly connected to the inner side of the threaded groove scale plate 312. When the bidirectional ball screw 302 rotates, it drives the two sets of adjusting sleeves 303 to move closer to each other. When the bidirectional ball screw 302 rotates in the opposite direction, it drives the two sets of adjusting sleeves 303 to move further away from each other. One end of one set of adjusting sleeves 303 away from the bidirectional ball screw 302 is connected to a horizontal plate 304 by bolts. The inner side of the horizontal plate 304 is slidably connected to an adjusting scraper.

[0042] The adjusting scraper includes a scraper plate 305 slidably connected to the inner side of the horizontal plate 304. A rolling support is provided below the adjusting scraper. The servo motor 308 is started to drive the bidirectional ball screw 302 to rotate, thereby driving the two sets of adjusting sleeves 303 to move closer or further apart. The rolling support includes a base plate 306 located below the horizontal plate 304. A roller 307 is rotatably connected to the inner wall of the base plate 306 through a bearing. The roller 307 supports the bottom surface of the fabric and, in conjunction with the fabric conveying operation, the adjusting sleeves 303 drive the horizontal plate 304 and the roller 307 to move closer or further apart. Adjustments are made according to the scale 313 until the distance between the scraper plate 305 and the servo motor 308 is adapted to the fabric thickness. The base plate 306 is bolted to the end of the other set of adjusting sleeves 303. The two sets of adjusting sleeves 303 can drive the roller 307 and the scraper plate 305 to move synchronously, thereby achieving the purpose of adapting to fabrics of different thicknesses.

[0043] Two sets of scraper plates 305 are provided, and the surface of the scraper plate 305 is coated with an anti-stick coating, such as Teflon, to reduce the adhesion of paint slurry. A connecting groove is provided inside the horizontal plate 304. The top of the scraper plate 305 extends into the inside of the connecting groove and slides with the inside of the connecting groove. Therefore, the scraper plate 305 can be adjusted laterally under the horizontal plate 304.

[0044] The interior of the horizontal plate 304 is provided with a moving groove 314, which is connected to the top surface of the horizontal plate 304. The top end of the one-way threaded rod 315 passes through the interior of the moving groove 314 and extends to the exterior of the horizontal plate 304. When the scraper plate 305 slides laterally, it drives the one-way threaded rod 315 to move inside the moving groove 314. The center position of the top surface of the scraper plate 305 is rotatably connected to the one-way threaded rod 315 through a bearing.

[0045] A fixing block 316 is fitted on the outer side of the one-way threaded rod 315. The one-way threaded rod 315 is threadedly connected to the inner side of the fixing block 316. When the top of the one-way threaded rod 315 is held and rotated continuously, the fixing block 316 is pushed upward to release the fixing state of the scraping plate 305, which facilitates the adjustment of the distance between the two sets of scraping plates 305 to adapt to flexible fabrics of different sizes. After holding the one-way threaded rod 315 and rotating it in the opposite direction, the fixing block 316 is pushed downward vertically until it is in close contact with the top surface of the horizontal plate 304. At this time, the fixing work of the scraping plate 305 is completed. A scale 313 is connected to the outer wall of the mounting bracket 301 by screws. According to the scale 313, the distance between the scraping plate 305 and the roller 307 can be adjusted, which improves the accuracy of the distance adjustment.

[0046] Example 3

[0047] Please see Figure 1-5 A support vertical plate 310 is connected to the inner wall of a set of mounting cavities 309 by screws. Two sets of sliding sleeves 311 are slidably sleeved on the outer side of the support vertical plate 310. One set of sliding sleeves 311 is fixedly connected to the end of the horizontal plate 304 away from the adjusting sleeve 303, and the other set of sliding sleeves 311 is connected to the end of the bottom plate 306 away from the adjusting sleeve 303 by screws. When the horizontal plate 304 moves up and down, it drives the sliding sleeves 311 to slide vertically on the outer side of the support vertical plate 310. The sliding sleeves 311 and the support vertical plate 310 provide support and cooperate in the movement of the part of the horizontal plate 304 away from the adjusting sleeve 303.

[0048] Working principle: First, the coating device is started through the control panel. The unwinding mechanism 5 conveys the flexible fabric into the interior of the coating machine 2. The coating machine 2 starts to coat the flexible fabric. After coating, the flexible fabric passes through the interior of the scraping section 3. The roller 307 supports the bottom surface of the fabric. At the same time, in coordination with the fabric conveying, the scraping plate 305 scrapes the fabric to keep the coating thickness on the fabric surface uniform.

[0049] Secondly, when it is necessary to coat fabrics of different thicknesses, the servo motor 308 is started through the control panel. The output end of the servo motor 308 drives the bidirectional ball screw 302 to rotate, thereby pushing the two sets of adjusting sleeves 303 to move closer or further apart. The adjusting sleeves 303 drive the horizontal plate 304 and the roller 307 to move closer or further apart. Adjustment is made according to the scale 313 until the distance between the scraping plate 305 and the roller 307 is adapted to the fabric thickness.

[0050] Finally, when the top of the one-way threaded rod 315 is held and rotated continuously, the fixed sleeve block 316 is pushed upward to move, releasing the fixed state of the scraper plate 305. Therefore, the distance between the two sets of scraper plates 305 can be adjusted according to the size of the fabric to adapt to flexible fabrics of different sizes, and finally the work is completed.
