Description

Technical Field

[0001] This utility model relates to the field of leather production technology, and in particular to a fabric flattening and drying device after fabric is crumpled. Background Technology

[0002] Synthetic leather is a high-performance material widely used in various industries. Its processing technology includes substrate preparation, coating application, texture treatment, and final flattening and drying. After texture treatment, a specific texture will be formed on the surface of synthetic leather. Although this process gives synthetic leather a unique tactile and appearance effect, it also causes its surface to have wavy undulations. Therefore, it is necessary to flatten its surface through the flattening process to ensure that the subsequent drying process can proceed smoothly.

[0003] Currently, most synthetic leather flattening processes rely on manual operation. While manual flattening can address surface unevenness to some extent, it is inefficient and prone to producing unevenness. The problem of uneven drying is even more pronounced in the synthetic leather drying process. Due to the complex surface texture of synthetic leather after the rubbing process, and the fact that drying equipment is mostly located at the top of the drying chamber, heat is unevenly distributed during the drying process. This can easily lead to some areas (such as the top surface of the synthetic leather) being over-dried, while other areas (such as the bottom surface) remain damp. This uneven drying effect not only affects the appearance of the synthetic leather, potentially causing color differences or texture distortion, but it can also affect the subsequent winding process, causing quality problems such as curling deformation or wrinkling, thus impacting the final product's pass rate.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

[0005] This utility model provides a flattening and drying device for fabric after texturing, aiming to solve the problems of low flattening efficiency and uneven drying in the existing flattening and drying steps of synthetic leather after texturing.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A fabric flattening and drying device after fabric crumpling includes a base. With the length of the base as the left-right direction, the top surface of the base is sequentially provided from left to right with an inlet roller, a flattening mechanism, a guide roller, a drying mechanism, and an outlet roller. The flattening mechanism includes a first tensioning roller and a second tensioning roller for tensioning the base fabric. A flattening roller for flattening the base fabric is provided between the first and second tensioning rollers. The flattening roller consists of two rollers arranged side-by-side at intervals, with opposite spiral patterns on the two rollers. The drying mechanism includes a drying chamber and a hot air blower. The left and right sides of the drying chamber are respectively provided with a base fabric inlet and a base fabric outlet. The hot air blower is provided with a first air outlet and a second air outlet. The top and bottom sides of the drying chamber are respectively provided with a gradually expanding first air inlet and a second air inlet. The first air outlet and the second air outlet are connected to the first air inlet and the second air inlet via a first air duct and a second air duct. An exhaust vent for discharging air from the drying chamber is also provided on one side of the first air inlet.

[0008] Furthermore, the first air inlet and the second air inlet mentioned above are funnel-shaped openings.

[0009] Furthermore, the gradually expanding opening ends of the first air inlet and the second air inlet are respectively provided with a first guide plate and a second guide plate with the same opening angle.

[0010] Furthermore, the aforementioned hot air blower includes a heater and a blower.

[0011] As can be seen from the above description of the structure of this utility model, this utility model has the following advantages:

[0012] Firstly, this invention incorporates a flattening mechanism and a drying mechanism on a base. The flattening mechanism, using flattening rollers with opposite spiral patterns, effectively removes the wavy undulations on the surface of the synthetic leather after the rubbing process, ensuring the flatness of the base fabric. The drying mechanism supplies hot air into the drying chamber via a hot air blower. Because the drying chamber has gradually expanding first and second air inlets at the top and bottom of the side walls, the hot air is evenly distributed. This allows the hot air at the top to circulate downwards, while the hot air at the bottom pushes the hot air upwards, preventing hot air from concentrating at the top. This ensures that the hot air is evenly distributed and effectively dries the base fabric, guaranteeing the uniformity of the drying process. It avoids situations where the top area of ​​the base fabric is over-dried while the bottom area remains damp after drying. This not only improves the efficiency of the flattening step but also reduces subsequent quality problems such as color difference, texture distortion, and subsequent curling, deformation, or wrinkling, significantly improving the quality of the finished synthetic leather.

[0013] Secondly, both the first and second air inlets of this utility model are funnel-shaped openings, and the gradually expanding opening ends of the first and second air inlets are respectively provided with a first guide plate and a second guide plate with the same opening angle. This setting can help reduce the turbulence of air flow and ensure that the hot air can diffuse smoothly when entering the drying box, thereby further optimizing the entire drying process and making the drying of the base fabric more uniform and efficient.

Detailed Implementation

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0019] Reference Figures 1 to 3A fabric flattening and drying device after fabric crumpling includes a base 10. With the length of the base 10 as the left-right direction, the top surface of the base 10 is sequentially provided from left to right with an inlet roller 20, a flattening mechanism, a guide roller 40, a drying mechanism, and an outlet roller 60. The flattening mechanism includes a first tensioning roller 31 and a second tensioning roller 32 for tensioning the base fabric. A flattening roller 33 for flattening the base fabric is provided between the first tensioning roller 31 and the second tensioning roller 32. The flattening roller 33 consists of two rollers 34 arranged side-by-side at intervals, with opposite spiral patterns 35 on the two rollers 34. The drying mechanism includes a drying chamber 51 and a hot air blower 52. The drying chamber 51 has a base fabric inlet 511 and a base fabric outlet 512 on its left and right sides, respectively. The hot air blower 52 has a first air outlet 53 and a second air outlet 54. The top and bottom sides of the drying chamber 51 have a gradually expanding first air inlet 513 and a second air inlet 514, respectively. The first air outlet 53 and the second air outlet 54 are respectively connected to a first air duct 55 and a second air duct 56. The ends of the first air duct 55 and the second air duct 56 are respectively connected to the first air inlet 513 and the second air inlet 514. The first air inlet 513 also has an exhaust vent 515 on one side for discharging air from the drying chamber 51.

[0020] In application, the crumpled base fabric is first fed into the equipment through the inlet roller 20. The base fabric then sequentially passes around the first tension roller 31, the spreading roller 33, and the second tension roller 32. The first and second tension rollers 31 and 32 provide appropriate tension to ensure the base fabric does not wrinkle at the spreading roller 33. The spreading roller 33, through the action of two parallel rollers 34 with opposing spiral patterns 35, flattens the surface of the base fabric, removes crumpling, and keeps the base fabric flat. The flattened base fabric continues to be conveyed through the guide roller 40 to the drying chamber 51 of the drying mechanism, where hot air is supplied by the hot air blower 52. The hot air enters through gradually expanding air inlets located at the top and bottom sides of the drying chamber 51, achieving uniform distribution of hot air. This allows the hot air at the top to circulate downwards, while the hot air at the bottom pushes the hot air upwards, preventing hot air from concentrating at the top and ensuring even distribution and effective drying of the base fabric. Simultaneously, moisture is discharged through the exhaust vent 515, maintaining a clean and well-ventilated drying environment. Finally, the fully dried base fabric is guided out of the equipment by the guide roller 60 and wound up by the winding machine (not shown in the figure), thus completing the entire flattening and drying process.

[0021] Reference Figures 1 to 3Both the first air inlet 513 and the second air inlet 514 are funnel-shaped openings, and the gradually expanding opening ends of the first air inlet 513 and the second air inlet 514 are respectively provided with a first guide plate 516 and a second guide plate 517 with the same opening angle. With this setting, hot air can be effectively guided into the drying chamber 51 and the air flow can be made more uniform. The design of the first guide plate 516 and the second guide plate 517 with the opening angle of the air inlet can help reduce the turbulence of the air flow and ensure that the hot air can be smoothly diffused when entering the drying chamber 51, thereby further optimizing the entire drying process and making the drying of the base fabric more uniform and efficient.

[0022] Reference Figures 1 to 3 The hot air blower 52 includes a heater 521 and a blower 522. Since it is a conventional existing device, it will not be described in detail here, and it is only briefly shown in the figure.

[0023] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
