Description

Technical Field

[0001] This utility model relates to the field of artificial leather processing technology, specifically a drying device for artificial leather production and processing. Background Technology

[0002] Artificial leather is a plastic product that looks and feels like leather and can be used as a substitute. It is usually made by coating a fabric base with synthetic resin and various plastic additives. In the production process of artificial leather, drying is required to remove moisture from the material and accelerate the drying and shaping of the coating material. Therefore, appropriate drying equipment is needed.

[0003] Existing drying devices used in the production and processing of artificial leather mostly transport the artificial leather in a straight line. With the air source position fixed, straight transport results in a limited area where the air force acts on the artificial leather, and the artificial leather only enjoys the maximum air force at the point closest to the air source. The air force decreases with distance, affecting the drying effect. Furthermore, existing blower devices have less contact time between the air force and the heating device when generating air force, which cannot effectively heat the air force, thus affecting the subsequent drying effect. Therefore, we propose a drying device for the production and processing of artificial leather. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a drying device for artificial leather production and processing. This device features a reliable material conveying unit. An outer protective frame and an inner limiting rod form an open channel for conveying artificial leather, enabling the artificial leather material to be conveyed in an Ω-shaped curved manner. This increases the effective area and processing time for air drying, thereby effectively improving the drying effect. Furthermore, the air source blows out in a fan-shaped area from the center, ensuring consistent airflow across the artificial leather surface and further enhancing the drying effect. It also includes a reliable hot air supply unit. Heating wires evenly heat the heat-conducting metal plate. The air source enters from the center of the spiral-shaped heat-conducting metal plate, rotates continuously inside, and exits through the air duct. The spiral-shaped heat-conducting metal plate ensures sufficient contact time between the airflow and the heat-conducting metal plate, improving the heating effect and further enhancing the drying efficiency of the artificial leather. This effectively solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for artificial leather production and processing, comprising a vertical frame, a material conveying unit, and a hot air supply unit;

[0006] Vertical panel frame: A rectangular panel that is set horizontally but remains vertical;

[0007] Material conveying unit: includes air guide cover, air outlet, outer guard frame, inner limit rod, drive roller and motor. The front end of the vertical plate frame is fixedly connected to the outer guard frame in the shape of the letter Ω. An inner limit rod is installed and fixed near the inner wall of the outer guard frame. The inner limit rod is fixedly connected vertically to the vertical plate frame and is on the same arc line as the inner limit rod. A drive roller is rotatably connected at the 3 o'clock, 9 o'clock and 12 o'clock positions respectively. The diameter of the drive roller is larger than the diameter of the inner limit rod. A ring of friction strips is fixedly connected in a circular array on the outer circumference of the drive roller. A motor is installed on the back of the vertical plate frame at the position corresponding to each drive roller. The front end plate of the motor is fixedly connected to the vertical plate frame by bolts. A circular air guide cover is fixedly connected at the front end of the vertical plate frame and at the center of the arc segment of the outer guard frame. An air outlet with a range of 240° is opened on the circumference side of the upper end of the air guide cover. The air outlet is connected to the air supply channel inside the air guide cover.

[0008] Hot air supply unit: installed on the rear side of the vertical plate frame.

[0009] The outer guardrail and inner limit rods form an open channel for conveying artificial leather, causing the passing artificial leather to bend into an Ω-shaped structure. An electric motor drives three drive rollers to rotate. The drive rollers, installed at the 3 o'clock, 9 o'clock, and 12 o'clock positions, effectively convey the artificial leather material through their enlarged diameter and outer friction strips. The air guide cover forms a 240° fan-shaped air zone through the upper air outlet. The air force passes through the gaps between the inner limit rods and acts on the artificial leather passing through the channel. By conveying the artificial leather material in an Ω-shaped bend, the time for the artificial leather to be dried by air can be increased, thereby effectively improving the drying effect of the artificial leather. Moreover, the air source blows out from the central position in a fan-shaped area, ensuring that the air force acting on the surface of the artificial leather is consistent.

[0010] Furthermore, the material conveying unit also includes lower support plates and exhaust ports. Two lower support plates are fixedly connected to the lower front end of the vertical frame, and these two lower support plates are parallel to the horizontal ends of the left and right sides of the Ω-shaped outer support frame. An evenly spaced ring of exhaust ports is formed inside the arc-shaped section of the outer support frame. The two lower support plates, together with the horizontal ends of the left and right sides of the Ω-shaped outer support frame, form the inlet and outlet. The exhaust ports allow the airflow blowing towards the outer support frame to flow outwards, thereby ensuring air circulation inside and outside the outer support frame and ensuring good drying effect.

[0011] Furthermore, the hot air supply unit includes a hot air box, a heat-conducting metal plate, heating wires, and a second air duct. The hot air box is installed at the rear center of the vertical frame. The hot air box is composed of a disc-shaped main body and a section of direct structure integrally fixedly connected. A spiral-shaped heat-conducting metal plate is installed inside the disc-shaped hot air box, and heating wires are embedded within the heat-conducting metal plate. The front side of the right-angle section of the hot air box is fixedly connected to the second air duct. The rear end of the second air duct is connected to the interior of the hot air box, and the front end is connected to the air delivery channel inside the air guide cover. The hot air box is used for mounting the heat-conducting metal plate. The heating wires can heat the heat-conducting metal plate evenly. The air source enters from the center of the spiral-shaped heat-conducting metal plate, rotates continuously inside the heat-conducting metal plate, and is discharged through the second air duct. The spiral-shaped heat-conducting metal plate ensures sufficient contact time between the airflow and the heat-conducting metal plate, thereby improving the heating effect of the airflow and further improving the drying efficiency of the artificial leather.

[0012] Furthermore, the hot air supply unit also includes an air duct, a mounting base, and a blower. The mounting base is fixedly connected to the lower left corner of the rear side of the vertical plate frame. A blower is fixedly mounted on the upper end of the mounting base. The air duct is fixedly connected to the air outlet of the blower, and the other end of the air duct leads to the center of the volute-shaped heat-conducting metal plate. The mounting base is used to install the blower, which generates airflow and delivers it along the air duct to the center of the volute-shaped heat-conducting metal plate.

[0013] Furthermore, the hot air supply unit also includes a mounting base and a temperature control knob. The mounting base is fixedly connected to the lower part of the rear center of the vertical frame. The mounting base supports the lower side of the hot air box, and a temperature control knob is installed on the rear side of the mounting base. The input end of the heating wire is electrically connected to the output end of an external power supply through the temperature control knob. The mounting base is used for mounting and supporting the hot air box, and the temperature control knob is used to adjust the heating power and temperature of the heating wire.

[0014] Furthermore, the hot air supply unit also includes a temperature monitor. The temperature monitor is embedded in the center of the front end of the air guide cover, with its detection end extending into the air delivery channel inside the air guide cover. A digital display screen is located at the front end of the temperature monitor. The temperature monitor is used to monitor and display the temperature of the hot air at the air guide cover, thereby facilitating the operator's adjustment of the hot air temperature.

[0025] Please see Figures 1-4 This embodiment provides a technical solution: a drying device for artificial leather production and processing, including a vertical plate frame 1, a material conveying unit 2 and a hot air supply unit 3;

[0026] Vertical panel 1: A rectangular panel that is set horizontally and keeps vertical;

[0027] Material conveying unit 2 includes an air guide cover 21, an air outlet 22, an outer guard frame 23, an inner limit rod 24, a drive roller 25, and a motor 28. An Ω-shaped outer guard frame 23 is fixedly connected to the front end of the vertical frame 1. An inner limit rod 24 is fixedly installed near the inner wall of the outer guard frame 23. The inner limit rod 24 is perpendicularly fixed to the vertical frame 1 and is on the same arc as the inner limit rod 24. A drive roller 25 is rotatably connected at the 3 o'clock, 9 o'clock, and 12 o'clock positions. The diameter of the drive roller 25 is larger than that of the inner limit rod 24.

[0028] Hot air supply unit 3: installed on the rear side of the vertical plate frame 1.

[0029] The outer guardrail 23 and the inner limiting rod 24 form an open channel for conveying artificial leather, causing the artificial leather to bend into an Ω-shaped structure. The motor 28 drives three drive rollers 25 to rotate.

The air guide cover 21 forms a fan-shaped air zone with a range of 240° through the air outlet 22 on the upper side. The air force passes through the gap between the inner limiting rods 24 and acts on the artificial leather passing through the channel.

The two lower support plates 26, together with the horizontal ends of the left and right sides of the Ω-shaped outer support frame 23, form the inlet and outlet. The exhaust ports 27 allow the airflow blowing towards the outer support frame 23 to flow outwards, thereby ensuring air circulation inside and outside the outer support frame 23 and ensuring good drying effect.

[0031] The hot air supply unit 3 includes a hot air box 32, a heat-conducting metal plate 33, an electric heating wire 34, and a second air duct 36. The hot air box 32 is installed at the middle of the rear side of the vertical frame 1. The hot air box 32 is formed by a disc-shaped main box and a section of direct structure that are integrally fixedly connected. The disc-shaped hot air box 32 has a spiral heat-conducting metal plate 33 installed inside. The electric heating wire 34 is embedded inside the heat-conducting metal plate 33. The second air duct 36 is fixedly connected to the front side of the right-angle section of the hot air box 32. The rear end of the second air duct 36 is connected to the interior of the hot air box 32, and the front end of the second air duct 36 is connected to the air supply channel inside the air guide cover 21. The hot air box 32 is used for the installation of the heat-conducting metal plate 33. The heating wire 34 can heat the heat-conducting metal plate 33. The air source is introduced from the center of the spiral heat-conducting metal plate 33, rotates continuously inside the heat-conducting metal plate 33 and is discharged through the air duct 36. By setting the spiral heat-conducting metal plate 33, it can be ensured that the air force and the heat-conducting metal plate 33 have sufficient contact time, thereby improving the heating effect of the air force and further improving the drying efficiency of artificial leather.

[0032] The hot air supply unit 3 also includes an air duct 35, a mounting base 37, and a blower 38.

[0033] The hot air supply unit 3 also includes a mounting base 31 and a temperature control knob 39. The mounting base 31 is fixedly connected to the lower part of the rear middle of the vertical frame 1. The mounting base 31 supports the lower side of the hot air box 32, and the temperature control knob 39 is installed on the rear side of the mounting base 31.

[0035] The working principle of the drying device for artificial leather production and processing provided by this utility model is as follows: When using this device, the artificial leather is drawn out from the roller body and fed into the feed port formed by the clamping of the outer guard frame 23 and the right lower support plate 26. It passes through the open channel formed by the outer guard frame 23 and the inner limit rod 24 and is drawn out through the discharge port formed by the outer guard frame 23 and the left lower support plate 26. The motor 28 is used to drive the three drive rollers 25 to rotate. The drive rollers 25 installed at the 3 o'clock, 9 o'clock and 12 o'clock positions can effectively drive the artificial leather material to be transported through their enlarged diameter and the friction strip on the outside. As the artificial leather passes through the inner channel of the outer protective frame 23, it is clamped by the outer protective frame 23 and the inner limiting rod 24 to form an Ω-shaped structure, which increases the time for the artificial leather to be dried by air, thereby effectively improving the drying effect of the artificial leather. The air guide cover 21 forms a fan-shaped air zone with a range of 240° through the air outlet 22 on the upper side. The air force passes through the gap between the inner limiting rods 24 and acts on the artificial leather passing through the channel. Moreover, the air source blows out in a fan-shaped area from the center position, which can ensure that the air force acting on the surface of the artificial leather is uniform. The exhaust port 27 allows the air force blowing towards the outer protective frame 23 to flow outward, thereby ensuring the air circulation inside and outside the outer protective frame 23 and ensuring a good drying effect. Mounting base 2 37 is used for mounting the blower 38, which generates airflow and delivers it along the air duct 1 35 to the center of the spiral heat-conducting metal plate 33. The hot air box 32 is used for mounting the heat-conducting metal plate 33. The heating wire 34 heats the heat-conducting metal plate 33. The air source enters from the center of the spiral heat-conducting metal plate 33, rotates continuously inside the plate, and is discharged through the air duct 2 36. The spiral heat-conducting metal plate 33 ensures sufficient contact time between the airflow and the plate, thereby improving the heating effect and further enhancing the drying efficiency of the artificial leather. Additionally, mounting base 1 31 is used for mounting and supporting the hot air box 32, the temperature control knob 39 is used to adjust the heating power and temperature of the heating wire 34, and the temperature monitor 310 is used to monitor and display the temperature of the hot air at the air guide cover 21, facilitating temperature control by the operator.

[0036] It is worth noting that the input terminals of the motor 28, blower 38, and temperature monitor 310 disclosed in the above embodiments are electrically connected to the output terminal of the external power supply through an external control switch group, and the input terminal of the heating wire 34 is electrically connected to the output terminal of the external power supply through a temperature adjustment knob 39.
