Description

Technical Field

[0001] This utility model relates to the field of synthetic leather processing technology, specifically to a water-based synthetic leather drying equipment. Background Technology

[0002] Water-based synthetic leather is an environmentally friendly synthetic leather that uses water as a solvent. It is made by coating or impregnating a base fabric with water-based polyurethane and other materials. It does not contain the toxic volatile substances found in traditional solvent-based synthetic leather, making it more environmentally friendly. The drying process is a key step in the production of water-based synthetic leather. It must be carried out in an oven at a specific temperature, where the moisture in the coating is evaporated through hot air circulation, allowing the water-based resin to cure and solidify. This ensures a smooth leather surface, stable performance, and prevents problems such as cracking or wrinkling.

[0003] A search revealed Chinese Patent Publication No. CN213142615U, which discloses a water-based synthetic leather drying device. The device includes a housing with a door fixedly installed on the right outer wall. A mounting bracket is welded to the upper interior of the housing. An insertion slot is provided on the top left side of the housing, and a moisture-absorbing plate is inserted into the slot. By using this structure, moisture generated during the drying process can be absorbed, preventing moisture from falling onto the surface of the synthetic leather and affecting the drying effect.

[0004] Existing technologies often have the following problems when used: Water-based synthetic leather drying equipment typically supports only one direction of hot air drying, which can lead to uneven heating and affect the drying efficiency. Furthermore, water-based synthetic leather is prone to wrinkles or bends before drying, and these wrinkles are difficult to dry evenly during the drying process, thus affecting the quality of the dried synthetic leather. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a water-based synthetic leather drying equipment, which can effectively solve the problems of the existing water-based synthetic leather drying equipment having a single hot air direction and the synthetic leather being prone to wrinkling or bending before drying, resulting in uneven heating of the synthetic leather and affecting the drying efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a water-based synthetic leather drying device, comprising: A drying oven, wherein a support frame is fixedly connected to the bottom surface of the drying oven, and a breathable mesh plate is fixedly connected to the top of the support frame, the breathable mesh plate being used to place water-based synthetic leather; A multi-directional drying assembly includes a hot air generator fixedly installed on the bottom surface of the drying chamber, air ducts fixedly connected to both side walls of the support frame, several L-shaped connecting pipes fixedly connected to the top ends of the two air ducts, two side air outlet frames fixedly connected to the top ends of the several L-shaped connecting pipes, and two air guiding components fixedly connected to the bottom surface of the drying chamber. The drying oven has two opposing side walls that are rotatably connected to quick-leveling components.

[0007] Furthermore, the air guide component includes a high-speed motor fixedly installed on the bottom surface of the drying chamber, with a fan blade fixedly connected to the output end of the high-speed motor. The fan blade is located inside the air guide duct, and the output end of the high-speed motor is fixedly connected to the end of the rotating shaft via a coupling.

[0008] Furthermore, the rapid leveling assembly includes a ball screw rotatably connected to the side wall of the drying chamber, a slider threaded onto the outer peripheral wall of the ball screw, a transverse support fixedly connected to the outer wall of the slider via a connecting bracket, and a pressure roller rotatably connected to the bottom end of the transverse support.

[0009] Furthermore, the rapid leveling assembly also includes a servo motor fixedly installed on the outer wall of the drying oven, and the output end of the servo motor is fixedly connected to the end of the ball screw.

[0010] Furthermore, a limiting frame is fixedly connected to the inner wall of the drying oven, and the end of the limiting frame away from the inner wall of the drying oven is rotatably connected to the end of the ball screw. A strip-shaped sliding hole is provided on the side wall of the limiting frame, and the connecting bracket slides with the limiting frame through the strip-shaped sliding hole.

[0011] Furthermore, the top of the drying oven is provided with a ventilation opening, the side wall of the drying oven is provided with an operation window, and a sealing plate is hinged to the outer wall of the drying oven above the operation window.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: This invention incorporates a multi-directional drying component. A hot air generator supplies hot air to the synthetic leather from below, while a high-speed motor drives the guide fan blades to rotate rapidly. This allows the guide fan blades to draw the hot air into the air duct, and then discharge the hot air to the synthetic leather from the side through an L-shaped connecting pipe and a side air outlet frame. This enables multi-directional hot air drying of the synthetic leather, effectively improving the uniformity and efficiency of the drying process.

[0013] This invention incorporates a rapid flattening component. A servo motor drives a ball screw to rotate, allowing a slider to rotate relative to the ball screw thread and move horizontally towards the inner wall of the drying chamber relative to the limiting frame. This enables the lateral movement frame to move synchronously towards the edge of the synthetic leather, thereby using pressure rollers to quickly flatten the wrinkles or bends of the synthetic leather. This ensures the flattening effect of the synthetic leather before drying, further guaranteeing the uniformity of drying and the quality of the synthetic leather drying process.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example: Refer to Figures 1 to 4A water-based synthetic leather drying device includes: a drying box 1 and a multi-directional drying component. The top of the drying box 1 is provided with a ventilation opening 17, and the side wall of the drying box 1 is provided with an operation window. A sealing plate 18 is hinged to the outer wall of the drying box 1 above the operation window. A support frame 2 is fixedly connected to the bottom surface of the drying box 1, and a breathable mesh plate 3 is fixedly connected to the top of the support frame 2. The breathable mesh plate 3 is used to place water-based synthetic leather. The multi-directional drying assembly includes a hot air generator 4 fixedly installed on the bottom surface of the drying chamber 1. The hot air generator 4 is a Vulcanic-10756.06 model. The two side walls of the support frame 2 are fixedly connected to air guide pipes 5. The top of the two air guide pipes 5 are fixedly connected to several L-shaped connecting pipes 6. The top of the several L-shaped connecting pipes 6 are fixedly connected to two side air outlet frames 7. The bottom surface of the drying chamber 1 is fixedly connected to two air guide components. The air guide components include a high-speed motor 8 fixedly installed on the bottom surface of the drying chamber 1. The high-speed motor 8 is a 57BLF-5000 model. The output end of the high-speed motor 8 is fixedly connected to a guide fan blade 9. The guide fan blade 9 is located inside the air guide pipe 5. Specifically, the high-speed motor 8 is equipped with a heat-insulating housing to prevent hot air from damaging the motor; Specifically, the breathable mesh plate 3 adopts a mesh hollow structure, which allows airflow to have good permeability. When hot air is discharged to the synthetic leather, it can carry away the moisture in the synthetic leather and carry the moisture out through the ventilation port 17 at the top of the drying box 1. Hot air is supplied to the synthetic leather from below through the hot air generator 4. At the same time, some of the hot air will accumulate in the support frame 2. At this time, the two high-speed motors 8 are controlled to run. The high-speed motors 8 can drive the guide fan blades 9 to rotate rapidly, so that the guide fan blades 9 can draw the hot air into the air guide pipe 5, and then discharge the hot air to the synthetic leather from the side through the L-shaped connecting pipe 6 and the side air outlet frame 7. This can realize multi-directional hot air drying of synthetic leather, effectively improving the drying uniformity and drying efficiency of synthetic leather.

[0019] The drying oven 1 has two opposing side walls rotatably connected to a quick-leveling assembly. The quick-leveling assembly includes a ball screw 10 rotatably connected to the side wall of the drying oven 1. A slider 11 is threaded onto the outer peripheral wall of the ball screw 10. A transverse foot 12 is fixedly connected to the outer wall of the slider 11 through a connecting bracket. A limit frame 15 is fixedly connected to the inner wall of the drying oven 1. The end of the limit frame 15 away from the inner wall of the drying oven 1 is rotatably connected to the end of the ball screw 10. A strip-shaped sliding hole 16 is opened on the side wall of the limit frame 15. The connecting bracket slides with the limit frame 15 through the strip-shaped sliding hole 16. A pressure roller 13 is rotatably connected to the bottom end of the transverse foot 12. The quick-leveling assembly also includes a servo motor 14 fixedly installed on the outer wall of the drying oven 1. The servo motor 14 is model 80DK-M07725. The output end of the servo motor 14 is fixedly connected to the end of the ball screw 10. Specifically, the two pressure rollers 13 are initially positioned in the middle of the breathable mesh plate 3, and the distance between the two pressure rollers 13 and the breathable mesh plate 3 is equal to the thickness of the water-based synthetic leather. When the synthetic leather is placed on top of the breathable mesh plate 3, it should pass through the gap between the two pressure rollers 13 and the breathable mesh plate 3 to ensure the smoothing effect of the pressure rollers 13 on the synthetic leather. The ball screw 10 is driven to rotate by the servo motor 14, so that the slider 11 can rotate relative to the ball screw 10 and move horizontally relative to the limit frame 15 close to the inner wall of the drying chamber 1. This allows the transverse foot 12 to move synchronously close to the edge of the synthetic leather, thereby using the pressure roller 13 to quickly flatten the wrinkles or bends of the synthetic leather, ensuring the flattening effect of the synthetic leather before drying, and further ensuring the drying uniformity and drying quality of the synthetic leather.

[0020] The working principle of this utility model is as follows: When drying water-based synthetic leather, the synthetic leather is first placed above the breathable mesh plate 3. The hot air generator 4 is then controlled to operate, so that the hot air generator 4 can supply hot air to the synthetic leather from below. At the same time, some hot air will accumulate in the support frame 2. At this time, two high-speed motors 8 are controlled to operate. The high-speed motors 8 can drive the guide fan blades 9 to rotate rapidly, so that the guide fan blades 9 can draw the hot air into the air guide pipe 5, and then discharge the hot air to the synthetic leather from the side through the L-shaped connecting pipe 6 and the side air outlet frame 7 in sequence. This can realize multi-directional hot air drying of synthetic leather, effectively improving the drying uniformity and drying efficiency of synthetic leather. After the water-based synthetic leather is placed on the breathable mesh plate 3, it is necessary to keep the synthetic leather under the two pressure rollers 13. The servo motor 14 can be started first, and the ball screw 10 is driven to rotate through the servo motor 14, so that the slider 11 can rotate relative to the ball screw 10 and move horizontally relative to the limit frame 15 close to the inner wall of the drying chamber 1. This allows the transverse foot 12 to move synchronously close to the edge of the synthetic leather, so that the pressure rollers 13 can quickly flatten the wrinkles or bends of the synthetic leather, so as to ensure the flattening effect of the synthetic leather before the drying operation, and further ensure the drying uniformity and drying quality of the synthetic leather.

[0021] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
