Description

Technical Field

[0001] This utility model relates to the field of textile fabrics, specifically a fabric processing equipment for producing warm and windproof fabrics. Background Technology

[0002] Polyester fabrics are widely used in outdoor clothing, tents, and industrial textiles due to their excellent wrinkle resistance and shape retention. To impart warmth, waterproofing, and breathability to polyester fabrics, a coating process is usually required. The quality of the coating directly determines the waterproof performance and lifespan of the finished fabric, and the flatness and tension stability of the membrane material before bonding to the substrate are key factors affecting the coating quality.

[0003] In actual high-speed continuous production processes, the following technical bottlenecks still exist: 1. Lack of active flattening capability, making it difficult to eliminate "dead wrinkles": The rollers in existing equipment are usually rigid cylinders or passive guide rollers with textured surfaces. For extremely thin and smooth polyester fabrics, uneven force during traction easily causes weft wrinkles. Traditional threaded flattening rollers or curved rollers mainly rely on the static friction between the roller surface and the film material to generate a component force for flattening. However, the surface of polyester fabric is usually relatively smooth with a low coefficient of friction, causing the film material to easily slip on the roller surface, rendering passive flattening ineffective. Once creases or "dead wrinkles" appear on the film material before entering the lamination process, it will directly lead to the scrapping of the laminated product.

[0004] 2. Passive tension control, prone to air bubbles or stretching deformation: While the original roller structure secures the roll material via abutments, it lacks dynamic damping adjustment and tension buffering mechanisms. During unwinding, as the roll diameter decreases or the traction speed fluctuates, the rollers are prone to over-unwinding due to excessive inertia (loose film) or excessive stretching of the membrane material due to excessive resistance (deformation). Loose film leads to air bubbles at the bonding area, while excessive stretching damages the waterproof layer structure of the membrane material. Utility Model Content

[0005] The purpose of this utility model is to provide a fabric processing equipment for producing warm and windproof fabrics, so as to solve the problems of wrinkles caused by the lack of active flattening ability in the lamination process in the prior art, and bubbling or deformation caused by the lack of tension control.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A fabric processing device for producing warm and windproof fabric includes a base plate and a processing box. The processing box is installed on one side of the upper surface of the base plate, and an unwinding assembly is provided above the base plate. The unwinding assembly includes a roller, and a coated roll is wound around the outer wall of the roller. The roller is connected to the processing box through a support unit. Between the roller and the processing box, a tension buffer assembly and a flattening roller assembly are sequentially arranged along the coated conveying path. The flattening roller assembly includes a stationary mandrel, a rotating cage, and several sliding strips. The sliding strips are distributed circumferentially around the rotating cage and form a roller surface. The sliding strips are slidably connected to the rotating cage, and the sliding strips can periodically move axially back and forth relative to the stationary mandrel as the rotating cage rotates.

[0007] Furthermore, the stationary mandrel is fixedly mounted on the base plate, and a swashplate is fixedly provided in the middle section of the stationary mandrel. The swashplate is arranged in a figure-eight shape with opposite inclined surfaces. The rotating cage is sleeved on the outside of the stationary mandrel through bearings, and several axial grooves are provided on the surface of the rotating cage. The inner side of the sliding plate is provided with a guide groove corresponding to the swashplate.

[0008] Furthermore, the swash plate includes an expansion section and a contraction section; when the sliding plate rotates with the rotating cage to the working area above the roller and in contact with the film, the guide groove is located in the expansion section of the swash plate, driving the sliding plate to move axially outward to both ends of the roller respectively; when the sliding plate rotates to the non-contact area below the roller, the guide groove is located in the contraction section of the swash plate, driving the sliding plate to axially retract and reset.

[0009] Furthermore, the outer surface of the sliding strip is covered with a flexible material layer with a high coefficient of friction.

[0010] Furthermore, the support unit includes a mechanical damper, which comprises a friction disc, a compression spring, and an adjusting nut.

[0011] Furthermore, the tension buffer assembly includes a swing arm hinged to the substrate, a film-coating roller mounted at the end of the swing arm, a reset spring connected to the swing arm, and a counterweight; the film material drawn out from the film roll passes around the film-coating roller before entering the flattening roller assembly.

[0012] Compared with the prior art, the present invention has the following significant advantages: 1. Active flattening to eliminate wrinkles: By setting up cam-driven sliding strips, the mechanical energy of the rotating rollers drives the strips to produce a real axial outward movement when in contact with the fabric. This physical displacement stretches the fabric from the center to both ends with strong force. Compared with traditional friction-based flattening, its flattening effect is more significant and can effectively eliminate dead wrinkles on smooth fabrics.

[0013] 2. Constant tension control to prevent bubbling and deformation: Combining a mechanical damper and a tension buffer assembly, the former eliminates unwinding inertia, while the latter absorbs tension fluctuations during the traction process. Together, these ensure that the laminating film enters the bonding process under constant and appropriate tension, significantly improving product yield.

[0014] 3. Purely mechanical structure, low cost: The entire system does not require complex servo motors or sensor control. It achieves automatic adjustment through ingenious mechanical coordination. The structure is durable, the maintenance cost is low, and it is easy to upgrade and modify existing equipment. Attached Figure Description

Detailed Implementation

[0018] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0019] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1 Please see as follows Figure 1-4As shown, a fabric processing device for producing warm and windproof fabric includes a substrate 1 and a processing box 3. The processing box 3 (containing conventional coating mechanisms such as heating and pressing) is mounted on one side of the upper surface of the substrate 1, and an unwinding assembly is located above the substrate 1. The unwinding assembly includes a roller 2, with a coated roll wound around its outer wall. The roller 2 is connected to the processing box 3 via a support unit 4.

[0021] To address the issues of unstable tension and poor flattening effect in traditional equipment, this embodiment adds a tension buffer assembly 5 and a flattening roller assembly 6 sequentially along the film-coating conveying path between the roller 2 and the processing box 3.

[0022] Support unit 4 integrates a mechanical damper 41 based on the original rotary support. The mechanical damper 41 is located at the rotating shaft end of roller 2 and includes a stationary friction disc, a compression spring fitted onto the rotating shaft, and an adjusting nut screwed onto the shaft end. By tightening the adjusting nut, the spring is compressed, causing continuous frictional resistance as roller 2 rotates. This design effectively prevents the film from loosening due to inertia causing the coating roll to continue rotating when subsequent processes suddenly stop or decelerate.

[0023] Tension buffer assembly 5 is located on the discharge side of roller 2. It includes a swing arm 51 hinged to the side of substrate 1, with a smooth-surfaced overlay roller 52 rotatably mounted at the end of the swing arm 51. A return spring 53 (or a counterweight can be used alone or in conjunction with the swing arm 51) is connected to the swing arm 51, providing a downward pulling force to the swing arm 51. The film material drawn from the coating roll first passes downward around the overlay roller 52 in a "U" or "V" shaped path, and then enters the flattening roller assembly 6 upward. Working principle: When the traction speed of the processing box 3 increases, causing the tension to increase, the film material pulls the overlay roller 52 to swing upward against the spring force, releasing the length of the film material and buffering the tension peak; when the traction speed decreases and the tension decreases, the return spring 53 pulls the swing arm 51 to swing downward, tightening the film material. This floating structure achieves dynamic tension balance.

[0024] The flattening roller assembly 6 is located adjacent to the inlet of the processing box 3 and is the core component of this device. The flattening roller assembly 6 mainly consists of a stationary mandrel 61, a rotating cage 62, and several sliding slats 63.

[0025] The stationary mandrel 61 is fixed at both ends to supports on the base plate 1, remaining stationary during operation. Its key feature is the swashplate 64 fixed in the middle section. The swashplate 64 has opposite inclined planes, opening in a figure-eight shape. The rotating cage 62 is sleeved on the outside of the stationary mandrel 61 via bearings, and can rotate around the stationary mandrel 61 under the influence of the film material's friction. Several parallel axial grooves are formed on the surface of the cage.

[0026] The sliding slats 63 are installed in the grooves of the rotating cage 62 and can slide left and right along the axial direction. The slats are evenly distributed around the circumference and together form the working outer surface of the flattening roller assembly 6. Each sliding slat 63 has a guide groove 65 on its inner side, which engages with the track of the swashplate 64 on the stationary spindle 61. The outer surface of the sliding slats 63 is covered with a flexible material layer 66 with a high coefficient of friction (such as silicone strips) to ensure a firm grip on the polyester fabric and prevent slippage.

[0027] The track design of the swash plate 64 is divided into an expansion section (corresponding to the area above the roller, i.e., the area in contact with the film material) and a contraction section (corresponding to the area below the roller, i.e., the non-contact area).

[0028] When one of the sliding strips 63 rotates with the cage and enters the upper working area, its inner guide groove 65 enters the expansion section of the swashplate 64. Due to the action of the cam inclined surface, the sliding strip 63 (and the symmetrical sliding strip 63 on the other side) is forced to move axially outward from the middle to both ends. At this time, the strip is in close contact with the film material, and this outward movement physically pulls the film material apart, smoothing out the wrinkles.

[0029] When the sliding strip 63 rotates to the bottom non-contact area, the guide groove 65 enters the contraction section, and the sliding strip 63 retracts inward and resets under the action of the cam, preparing for the next cycle.

[0030] Usage process: The operator loads the film roll into roller 2 and adjusts the mechanical damper 41 to a suitable resistance. The film head is pulled out, passing over the film-coating roller 52 of the tension buffer assembly 5, and then over the flattening roller assembly 6. At the flattening roller assembly 6, the film is continuously stretched and flattened to both sides by the rotating sliding strip 63, and finally enters the processing box 3 flat to be heat-pressed and laminated with the polyester fabric.

[0031] This invention achieves constant tension conveying and active, strong flattening during fabric processing through the ingenious combination of purely mechanical structures, effectively solving the pain points in the prior art.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
