Description

TECHNICAL FIELD

[0001] The utility model relates to the field of microfiber leather preparation technology, and specifically relates to a microfiber leather folding-resistant and shape-retaining material preparation equipment. BACKGROUND

[0002] Superfine fiber synthetic leather, referred to as microfiber leather, is a non-woven fabric with a three-dimensional structure network made of superfine fiber short fibers through carding and needling, and is finally made into superfine fiber leather through processes such as wet processing, PU resin immersion, alkali reduction, skin polishing and dyeing and finishing. On the basis of the base cloth composed of superfine fibers, a PU coating is coated, which has extremely excellent wear resistance, excellent cold resistance, air permeability and aging resistance.

[0003] After the PU coating material is prepared, it needs to be immediately sprayed on the surface of the microfiber leather base cloth. A large amount of waste gas is generated during the material preparation and spraying process. The waste gas mixed with waste materials floats around the microfiber leather and is easily re-adsorbed on the surface of the microfiber leather, resulting in uneven distribution of the surface coating of the microfiber leather, which in turn affects the wear resistance, folding resistance and deformation resistance of the microfiber leather.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figures 1 to 3 The device shown is a microfiber leather folding and non-deformation material preparation equipment, including a base 1. Two sets of equipment supports 2 are fixedly connected to the upper side of the base 1. Microfiber leather base fabric 29 is arranged inside the equipment supports 2. A preparation module is arranged between the two sets of equipment supports 2. The preparation module includes a spray box 3, a spray box 33, a spray pipe 34, a material preparation box 35, a dust collection box 36, a dust collection pipe 37, a vacuum cleaner 38, and an exhaust gas treatment box 39. The material preparation box 35, the vacuum cleaner 38, and the exhaust gas treatment box 39 are all fixedly installed on the upper side of the base 1. The left and right ends of the spray box 3 are fixedly connected to the equipment supports 2 on the left and right sides, respectively. Feed troughs 31 are opened at both ends of the spray box 3. The material preparation box 35 is provided with a preparation chamber 351 and an equipment chamber 352. The side wall of the preparation chamber 351 is hollow. A stirring module is provided inside the preparation chamber 351. The stirring module includes a stirring shaft 353, a stirring rod 354, and a stirring motor 355.

[0033] During the feeding process, the microfiber leather base fabric 29 passes through the feed troughs 31 at both ends of the spraying box 3, while the polyurethane slurry is poured into the material preparation box 35 for mixing. The hollow preparation chamber 351 effectively maintains the internal temperature of the preparation chamber 351, allowing it to remain at a constant temperature for a long time. At the same time, the stirring shaft 353 and stirring rod 354 stir the internal material, keeping the material with good fluidity and preventing sedimentation, thus improving the uniformity of the material and making the sprayed material more uniform. This results in a more uniform cured coating on the surface of the microfiber leather base fabric 29, effectively improving the wear resistance, folding resistance, and deformation resistance of the microfiber leather base fabric 29.

[0034] See Figure 2 and Figure 3 The stirring shaft 353 is rotatably connected to the inner walls of the front and rear sides of the preparation chamber 351. Multiple stirring rods 354 are fixedly connected to the surface of the stirring shaft 353. The stirring motor 355 is fixedly installed on the rear side of the material preparation box 35. The output end of the stirring motor 355 is fixedly connected to the rear end of the stirring shaft 353. A high-pressure pump 356 is fixedly installed inside the equipment chamber 352. The discharge end of the high-pressure pump 356 is fixedly connected to the lower end of the spraying pipe 34. The upper surface of the spraying box 3 is a transparent panel 32. Two sets of spraying boxes 33 are fixedly connected to the left end of the upper surface of the spraying box 3. The front end of the spraying box 33 is fixedly connected to the upper end of the spraying pipe 34. Dust collection boxes 36 are fixedly connected to both the front and rear sides of the spraying box 3. The upper end of the dust collection pipe 37 is fixedly connected to the lower surface of the dust collection box 36. The lower end of the dust collection pipe 37 is fixedly connected to the suction end of the vacuum cleaner 38.

[0035] Specifically, during the coating process of the microfiber leather base fabric 29, the high-pressure pump 356 extracts the slurry from the preparation chamber 351 and transports it to the interior of the spray box 33 through the spraying pipe 34. The two sets of spray boxes 33 spray the surface of the microfiber leather base fabric 29. At the same time as spraying, the stirring motor 355 continuously drives the stirring shaft 353 and the stirring rod 354 to rotate, continuously stirring the polyurethane slurry, maintaining the fluidity of the polyurethane slurry, improving the uniformity of the polyurethane slurry, and thus effectively improving the uniformity of the spraying. During the spraying process, the vacuum cleaner 38, through the vacuum pipe 37 and the vacuum box 36, sucks up the exhaust gas and waste generated during the spraying process and sends the exhaust gas and waste to the interior of the exhaust gas treatment box 39. The exhaust gas treatment box 39 filters the exhaust gas before discharging it, improving environmental protection.

[0036] Meanwhile, the transparent panel 32 on the upper side of the spraying box 3 facilitates the observation of the spraying status of the microfiber leather base fabric 29, and the relatively sealed spraying box 3 maintains the cleanliness of its interior, reduces the impact of dust on the microfiber leather base fabric 29, improves the spraying quality, and can be equipped with a temperature control module to regulate the temperature inside the spraying box 3, so that the sprayed material can be cured better and improve the curing effect of the material.

[0037] See Figure 1 , Figure 4 and Figure 5 A cleaning roller 21 is rotatably connected to the outer end of the left equipment bracket 2, and a positioning roller 22 is rotatably connected to the outer end of the left equipment bracket 2. Positioning grooves 23 are opened on the front and rear surfaces of one end of the inner side of both sets of equipment brackets 2. Positioning blocks 24 are slidably connected inside the positioning grooves 23. Support rollers 25 are rotatably connected between the two sets of positioning blocks 24. Support frames 26 are fixedly connected between the front and rear sets of positioning blocks 24. Precision electric cylinders 28 are fixedly installed on the inner side of both sets of equipment brackets 2. A connecting block 27 is fixedly connected to the telescopic rod in the precision electric cylinder 28. The connecting block 27 is fixedly connected to the lower surface of the support frame 26.

[0038] In addition, during the feeding process of the microfiber leather base fabric 29, the microfiber leather base fabric 29 passes under the cleaning roller 21, then passes over the two sets of support rollers 25, and then passes under the positioning roller 22. During the spraying process, the telescopic rod in the precision electric cylinder 28 pushes the support rollers 25 upward to adjust the tension of the microfiber leather base fabric 29, so that the microfiber leather base fabric 29 maintains the optimal tension. During the spraying process, the tension of the microfiber leather base fabric 29 is adjusted in real time according to the changes in tension, further improving the uniformity of spraying, so that the surface of the microfiber leather base fabric 29 can be evenly coated, and improving the coating quality.

[0039] The working principle of this utility model is as follows: The hollow sidewalls improve the heat preservation of the preparation chamber 351. At the same time, the stirring motor 355 drives the stirring shaft 353 and stirring rod 354 to stir the internal materials, effectively maintaining the fluidity and uniformity of the internal materials. Then, the surface of the microfiber leather base fabric 29 is sprayed through the spray box 33, which effectively improves the uniformity of the material spraying. During the spraying process, the dust collection box 36 and the vacuum cleaner 38 work together to suck up the exhaust gas and waste generated during the spraying process, keeping the inside of the spray box 3 clean and effectively improving the spraying quality, thereby improving the wear resistance, folding resistance and deformation resistance of the microfiber leather base fabric 29.
