Description

Technical Field

[0001] This utility model relates to the field of artificial leather technology, specifically to an energy-saving coating equipment for artificial leather production. Background Technology

[0002] Artificial leather, also known as synthetic leather, is a synthetic material that mimics the texture and appearance of natural leather. It is usually made by coating or laminating one or more layers of synthetic resin (such as polyurethane PU, polyvinyl chloride PVC, etc.) and other additives onto the fabric as a base. It is designed to provide a similar feel, wear resistance and aesthetic effect to genuine leather, while reducing costs and meeting diverse application needs. In the artificial leather manufacturing industry, the coating and drying processes are the core steps to ensure product quality and production efficiency.

[0003] In the coating process, traditional equipment often lacks a precise control mechanism for coating thickness, which easily leads to uneven thickness during coating. This not only requires subsequent manual adjustments, increasing production costs, but may also affect the overall performance of the product due to coating that is too thick or too thin. At the same time, the pretreatment of the roll material before coating is not given enough attention, such as the cleanliness of the roll material surface and its temperature adaptability, which may have an adverse effect on the coating effect. To address this, we have proposed an energy-saving coating equipment for artificial leather production. Utility Model Content

[0028] Please see Figure 1-5 An energy-saving coating equipment for artificial leather production includes a support base 1, an unwinding rack 2 at one end of the upper side of the support base 1, a drying chamber 3 fixedly connected to the other end of the upper side of the support base 1, a winding rack 4 at the side of the support base 1 away from the unwinding rack 2, a hot air outlet pipe 5 fixedly connected to the side of the drying chamber 3 away from the unwinding rack 2, a control device 6 fixedly connected to the rear side of the support base 1, a feeding buffer plate 8 fixedly connected between the unwinding rack 2 and the drying chamber 3 on the upper side of the support base 1, the feeding buffer plate 8 being fixedly connected to the drying chamber 3 at one end near the drying chamber 3 and communicating with the inner cavity of the drying chamber 3, the upper side of the drying chamber 3 being open at one end near the unwinding rack 2, a coating plate 10 being provided on the inner walls of both sides of the drying chamber 3 at one end near the opening, and a hot air dryer 7 fixedly connected to the upper side of the drying chamber 3. The equipment also includes:

[0029] A drying device is installed in the inner cavity of the drying chamber 3 and is used to dry the coated artificial leather.

[0030] The tensioning device is located on the upper side of the drying chamber 3, so that the artificial leather has appropriate tension during the conveying process.

[0031] Furthermore, the inner cavity of the feed buffer plate 8 is hollow, and the first feed roller 9 is rotatably connected to both ends of the inner wall of the feed buffer plate 8.

[0032] Furthermore, two first electric push rods 16 are fixedly connected to the lower ends of the inner walls on both sides of the drying chamber 3, corresponding to the lower part of the coating plate 10. One end of each of the two first electric push rods 16 is rotatably connected to a connecting rod, and the other end of each connecting rod is fixedly connected to the coating plate 10. A rotating shaft is rotatably connected in the middle of the two connecting rods, and both ends of the rotating shaft are rotatably connected to the inner wall of the drying chamber 3. This design allows the coating plate 10 to be precisely adjusted according to actual needs to adapt to the coating requirements of artificial leather of different specifications and materials. The rotating shaft in the middle of the connecting rods further enhances the stability and reliability of this adjustment process.

[0033] Furthermore, a glue inlet pipe 12 is fixedly connected to one side of the glue coating plate 10. The end of the glue inlet pipe 12 away from the glue coating plate 10 is movably inserted into the inner wall of the drying chamber 3 and extends and is fixed to the side of the control device 6 away from the drying chamber 3. The pipe of the glue inlet pipe 12 is made of soft material.

[0034] Furthermore, the drying device includes a second feed roller 14, a fixed rod 15, a metering roller 17, and a discharge roller 19. Four fixed rods 15 arranged in a matrix are fixedly connected to the inner wall of the drying chamber 3. Multiple vertically zigzag second feed rollers 14 are rotatably connected to the inner wall of the drying chamber 3 corresponding to the lower part of the coating plate 10. Multiple horizontally zigzag discharge rollers 19 are rotatably connected to the inner wall of the drying chamber 3 corresponding to the end away from the coating plate 10. Two metering rollers 17 are rotatably connected to the upper part of the inner wall of the drying chamber 3 near the coating plate 10. The second feed roller 14, the fixed rod 15, the metering roller 17, and the discharge roller 19 together constitute a complex roll material conveying system. Through precise layout and rotational connection, they ensure that the roll material can be heated evenly in the drying chamber 3, avoiding local overheating or overcooling.

[0035] Furthermore, the drying device also includes a blower 21 and heating copper wires 22. The bottom of the hot air dryer 7 is connected to the inner cavity of the drying chamber 3. The blower 21 is fixedly connected to the top of the inner wall of the hot air dryer 7, and two sets of staggered heating copper wires 22 are fixedly connected to the lower end of the inner wall of the hot air dryer 7.

[0036] Furthermore, the tensioning device includes a tension adjusting roller 13, a second electric push rod 18, and a sliding track 20. Two symmetrically distributed second electric push rods 18 are fixedly connected to the upper end of the inner wall of the drying chamber 3 between the second feed roller 14 and the feed roller 19. The tension adjusting roller 13 is fixedly connected to the lower push rod of the two second electric push rods 18. Sliding tracks 20 are fixedly connected to the two ends of the tension adjusting roller 13 on both sides of the inner wall of the drying chamber 3. Both ends of the tension adjusting roller 13 are movably engaged in the sliding tracks 20 on both sides.

[0037] Furthermore, the inner wall of drying chamber 3 has a three-layer structure, consisting of galvanized steel plate 23, polyurethane foam 24, and stainless steel plate 25 from the outer wall to the inner wall. This unique three-layer design not only provides excellent structural strength and protection but also effectively reduces heat loss, improves drying efficiency, and protects the inner wall of the drying chamber from corrosion and wear, thereby extending the service life of the equipment.

[0038] Working principle: At the initial start of the equipment, the raw material artificial leather on the unwinding rack 2 is smoothly released and guided into the equipment through the first feed roller 9. The feed buffer plate 8 not only provides a transition space for the roll material from the unwinding rack 2 to the coating area, but also ensures that a certain distance is maintained between the roll material and the subsequent coating plate 10, preventing direct contact between the roll material and the coating roller. This effectively avoids uneven coating caused by direct contact, ensuring the stability and consistency of coating quality. Secondly, it prevents impurities or dust that may exist on the roll material from directly contacting the coating roller, protecting the cleanliness of the coating roller and extending its service life. Finally, this interval also provides the roll material with a preheating and adaptation time to the higher temperature before entering the formal heating and drying area, which helps the roll material better adapt to the subsequent drying process and improves drying efficiency.

[0039] Next, inside the drying chamber 3, the coating plate 10, precisely controlled by the first electric push rod 16 and the connecting rod, can flexibly adjust its position to adapt to the coating needs of artificial leather of different specifications and materials. The glue inlet pipe 12 on one side of the coating plate 10 evenly delivers glue or paint onto the coating plate, ensuring the uniformity and accuracy of the coating. After coating, the artificial leather continues to move forward in the drying chamber 3. At this time, the drying device begins to play a key role. The blower 21 starts, blowing hot air into the drying chamber 3, while the heating copper wire 22 is energized and heated, together forming a highly efficient drying system. In this system, hot air circulates within the drying chamber, uniformly and rapidly drying the coated artificial leather. This ensures rapid curing of the coating and improves the quality of the artificial leather. Excess hot air is discharged through the hot air outlet pipe 5, where it can be recovered by an external hot air recovery machine to achieve energy saving. To ensure stable tension of the artificial leather during transport, the tensioning device uses a second electric push rod 18 to push the tension adjusting roller 13 to slide flexibly on the sliding track 20, adjusting it according to the real-time tension of the artificial leather to effectively prevent loosening or breakage.

[0040] In addition, the inner wall of the drying chamber 3 adopts a unique three-layer structure design, consisting of stainless steel plate 25, polyurethane foam 24 and galvanized steel plate 23 from the outside to the inside. This not only provides good structural strength and protection performance, but also effectively reduces heat loss, improves drying efficiency, and protects the inner wall of the drying chamber from corrosion and wear.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
