Technical Field

[0001] This utility model belongs to the field of fabric production technology, and in particular relates to a device for preparing lightweight, compression-resistant warp-knitted elastic imitation leather fabric. Background Technology

[0002] In the field of modern textile materials, lightweight, compression-resistant warp-knitted elastic imitation leather fabrics are widely used in footwear, clothing, bags, automotive interiors, and furniture decoration due to their advantages such as low cost, adjustable performance, and ease of processing. Consumers' increasing demands for lightweight, comfortable, and durable products have led to a continuous growth in market demand for this type of fabric. The imitation leather fabric production process requires coating the fabric surface with an imitation leather coating, which is a key process to improve the fabric's performance, texture, and functionality.

[0003] Existing methods for coating imitation leather fabrics typically involve scraper coating or roller coating, which suffer from uneven coating thickness and low coating precision. This makes it difficult to coat fabrics of different thicknesses according to user needs, greatly reducing the applicability of the equipment. Therefore, a device for preparing lightweight, compression-resistant warp-knitted elastic imitation leather fabric is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a device for preparing lightweight, compression-resistant warp-knitted elastic imitation leather fabric, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for preparing a lightweight, compression-resistant warp-knitted elastic imitation leather fabric includes a workbench, a protective cover on the top of the workbench, a coating component inside the protective cover, a connecting pipe at one end of the coating component, and a suction pump at the other end of the connecting pipe.

[0007] The coating assembly includes a connecting box, a flow regulating valve at the bottom of the connecting box, a paint nozzle connected to the bottom of the flow regulating valve, a connecting plate on one side of the connecting box, grooves at both ends of the connecting plate connecting to limit telescopic rods, pressure rollers rotatably connected to the inner side of the limit telescopic rods, a connecting frame welded to one side of the limit telescopic rods, a fixing plate welded to the bottom of one end of the connecting frame, a scraper at the bottom of the fixing plate, hydraulic telescopic rods connected to both ends of the fixing plate, a limit rod fitted on the outer side of the hydraulic telescopic rods, and a second guide roller rotatably connected to one side of the limit rod.

[0008] In a further technical solution, the other end of the connecting pipe is connected to the connecting box, the connecting pipe is connected through the protective cover, and the paint spray head is inclined.

[0009] In a further technical solution, the number of the limiting telescopic rods is two, and the two limiting telescopic rods are respectively rotatably connected to both ends of the pressure roller.

[0010] In a further technical solution, a support plate is provided inside the protective cover, and the paint nozzle is located above the support plate and is inclined.

[0011] In a further technical solution, a first guide roller and a combing roller are rotatably connected between the two inner walls of the protective cover. There are two first guide rollers, one of which is located below the combing roller. A guide plate is provided on the top of the workbench. The guide plate is inclined. A storage box and a receiving box are provided inside the workbench. The top of the receiving box is slidably connected to one end of the guide plate. The scraper is located above the receiving box. The suction pump is connected through to one side of the storage box.

[0012] In a further technical solution, the number of limiting rods is two, and the two limiting rods are rotatably connected to both ends of the second guide roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a coating assembly where a flow regulating valve and a paint nozzle work together to precisely adjust the paint flow rate according to production needs, achieving accurate control over the coating thickness. Whether preparing thinner, high-performance clothing fabrics or thicker bag fabrics, it can meet coating requirements of different thicknesses, significantly improving the applicability of the equipment. The combined design of the pressure roller and scraper allows the pressure roller to pre-flatten the warp-knitted elastic fabric during the coating process, reducing the impact of uneven fabric surfaces on the coating. Subsequently, the scraper can remove excess coating and further correct the coating surface, making the coating thickness uniform and consistent, greatly improving the quality of the imitation leather fabric.

[0015] This utility model, with its limiting telescopic rod, hydraulic telescopic rod, and limiting rod, allows for flexible adjustment of the position and pressure of the pressure roller, scraper, and second guide roller according to the different thicknesses and materials of warp-knitted elastic fabrics. This enables the device to adapt to the coating processing of various types of fabrics, further enhancing the equipment's versatility and practicality. The inclined guide plate, in conjunction with the collection box, allows excess coating scraped by the scraper to automatically slide into the collection box, achieving automated waste collection, reducing manual cleaning workload, and avoiding environmental pollution and material waste caused by waste scattering, thus improving the environmental friendliness and economy of production.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figures 1-4 As shown, this utility model embodiment provides a preparation device for lightweight compression-resistant warp-knitted elastic imitation leather fabric, including a workbench 1, a protective cover 2 on the top of the workbench 1, a coating component 3 inside the protective cover 2, a connecting pipe 4 at one end of the coating component 3, and a suction pump 5 at one end of the connecting pipe 4.

[0025] The coating assembly 3 includes a connecting box 301. A flow regulating valve 302 is provided at the bottom of the connecting box 301. A paint nozzle 303 is connected to the bottom of the flow regulating valve 302. A connecting plate 304 is provided on one side of the connecting box 301. A limiting telescopic rod 305 is connected to the grooves at the bottom of both ends of the connecting plate 304. A pressure roller 306 is rotatably connected to the inner side of the limiting telescopic rod 305. A connecting frame 307 is welded to one side of the limiting telescopic rod 305. A fixing plate 308 is welded to the bottom of one end of the connecting frame 307. A scraper 309 is provided at the bottom of the fixing plate 308. Hydraulic telescopic rods 310 are connected to both ends of the fixing plate 308. A limiting rod 311 is sleeved on the outer side of the hydraulic telescopic rod 310. A second guide roller 312 is rotatably connected to one side of the limiting rod 311.

[0026] In this embodiment, by starting the suction pump 5, the coating can be continuously delivered to the connecting box 301 through the connecting pipe 4. The flow regulating valve 302 can precisely control the coating flow according to the preset coating thickness requirements. The height of the scraper 309 can be adjusted by adjusting the height of the hydraulic telescopic rod 310, thereby precisely controlling the thickness of the scraped coating and ensuring that the final coating thickness meets the requirements. At the same time, under the action of the connecting frame 307, the limiting telescopic rod 305 drives the pressure roller 306 to move up and down with the extension and retraction of the hydraulic telescopic rod 310. The pressure of the pressure roller 306 on the fabric after coating can be adjusted according to the thickness and characteristics of the fabric, initially compacting the coating, so that the coating adheres better to the fabric and reduces surface undulations. When it is necessary to change the coating thickness, it is only necessary to adjust the height of the scraper 309 by adjusting the hydraulic telescopic rod 310, and at the same time adjust the coating flow in conjunction with the flow regulating valve 302 to achieve the coating of different thicknesses.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, specifically, the other end of the connecting pipe 4 is connected to the connecting box 301, the connecting pipe 4 is connected through the protective cover 2, and the paint spray head 303 is inclined.

[0028] There are two limiting telescopic rods 305, and the two limiting telescopic rods 305 are rotatably connected to both ends of the pressure roller 306 respectively;

[0029] The protective cover 2 has a support plate 9 inside, and the paint nozzle 303 is located above the support plate 9. The paint nozzle 303 is inclined.

[0030] The protective cover 2 has a first guide roller 8 and a combing roller 7 rotatably connected between its two inner walls. There are two first guide rollers 8, one of which is located below the combing roller 7. The top of the workbench 1 is provided with a guide plate 11, which is inclined. The workbench 1 has a storage box 10 and a collection box 6 inside. The top of the collection box 6 is slidably connected to one end of the guide plate 11. The scraper 309 is located above the collection box 6. The suction pump 5 is connected through to one side of the storage box 10.

[0031] There are two limit rods 311, and the two limit rods 311 are rotatably connected to the two ends of the second guide roller 312 respectively.

[0032] In this embodiment, the first guide roller 8 and the second guide roller 312 rotate to guide the fabric to be transported smoothly along a fixed path, preventing the fabric from deviating and avoiding the coating effect being affected by fabric deformation. The inclined paint nozzle 303 allows the paint to be sprayed on the fabric at a suitable angle and coverage area, ensuring uniform coating. The inclined guide plate 11 allows the scraped excess coating to slide down into the collection box 6 under the action of gravity, realizing automatic collection of waste and avoiding waste scattering. At the same time, it is convenient for centralized processing and recycling. One side of the scraper 309 is triangular, which can better guide the scraped coating material into the collection box 6 for storage. The combing roller 7 can comb the fabric surface, remove impurities such as lint, ensure good adhesion between the coating and the fabric, and improve the adhesion of the coating.

[0033] The working principle of this utility model is as follows: First, by starting the suction pump 5, the paint can be continuously delivered to the connecting box 301 through the connecting pipe 4. The flow regulating valve 302 can precisely control the paint flow according to the preset coating thickness requirements. Then, by adjusting the height of the hydraulic telescopic rod 310, the height of the scraper 309 can be adjusted, thereby precisely controlling the thickness of the scraped coating and ensuring that the final coating thickness meets the requirements. At the same time, under the action of the connecting frame 307, the limiting telescopic rod 305 drives the pressure roller 306 to move up and down with the extension and retraction of the hydraulic telescopic rod 310, which can be adjusted according to... The thickness and characteristics of the fabric are adjusted, and the pressure of the coating roller 306 on the fabric is adjusted after coating to initially compact the coating, so that the coating adheres better to the fabric and reduces surface undulations. Finally, when it is necessary to change the coating thickness, simply adjust the hydraulic telescopic rod 310 to change the height of the scraper 309, and at the same time adjust the coating flow rate with the flow regulating valve 302 to achieve coating of different thicknesses. The inclined guide plate 11 allows the scraped excess coating to slide down the guide plate 11 into the collection box 6 under the action of gravity, realizing the automatic collection of waste, avoiding waste scattering, and facilitating centralized processing and recycling.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
