Description

Technical Field

[0001] The utility model relates to the field of synthetic leather, in particular to a drying device for synthetic leather production. Background Art

[0002] Ultrafine fiber synthetic leather is a synthetic leather with leather texture and touch prepared by using ultrafine fiber as raw material and solvent-free polyurethane resin impregnation or coating method. This synthetic leather has the texture and touch of leather, and has excellent wear resistance, folding resistance, aging resistance and other properties. Its appearance and feel are similar to leather and can be used instead of leather. Synthetic leather needs to use many steps in processing, among which the more important step is the drying step. In the production process, synthetic leather usually undergoes a series of chemical reactions, such as impregnation, coating, hardening, etc. In these chemical reactions, water or other solvents are sometimes used, which will introduce moisture into the synthetic leather. In addition, in order to make the synthetic leather softer and more comfortable, a layer of emulsion or resin is sometimes coated on its surface, and these emulsions or resins may also contain moisture. Since the surface of the synthetic leather has too much moisture, if it is directly placed in a drying device for drying, it may take a long drying time, resulting in huge power consumption of the equipment and waste. Therefore, it is necessary to do further processing before drying. For this reason, we propose a drying device for synthetic leather production. Utility Model Content

[0011] (III) Beneficial effects

[0012] Compared with the prior art, the utility model provides a drying device for synthetic leather production, which has the following

[0013] Beneficial effects:

[0014] 1. The drying device for synthetic leather production passes the synthetic leather through the bottom end of the scraper and then extends it through the drying device in the working box to the discharge trough and is wound on the winding roller. The turning handle drives the winding roller to rotate, so that the synthetic leather is wound and collected through the rotation of the winding roller. In the process of winding the synthetic leather, the synthetic leather is in a sliding state in the working box. The synthetic leather tilts the scraper while sliding. When the scraper tilts to one side, it drives the ring buckle to pull the tension spring to increase the side length, and makes the bottom end of the scraper fit with the upper surface of the synthetic leather to scrape out water stains. When the water stains are scraped off, water flows through The water flows into the water collecting tank through the gap between the feeding device and the scraper for collection and recycling. The drying device provides a drying effect for the synthetic leather during the sliding process of the synthetic leather. The limit baffle on the limit rod is for the device to stop working. The limit baffle fits the scraper to provide a fixing effect for the scraper to prevent the scraper from turning over due to the tension of the ring buckle driven by the tension spring. This device has a good effect in scraping off water stains, which can effectively avoid the synthetic leather from requiring a long drying time due to excessive water stains on the surface before drying, resulting in a waste of electric energy, effectively saving costs, further improving the reduction of water stains on the surface of synthetic leather, and improving product quality.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7 A drying device for synthetic leather production comprises a work box 1, a discharging trough 2 for feeding is provided on the side of the work box 1, the discharging trough 2 runs through the side of the work box 1, a mounting frame 4 is fixedly installed on the side of the work box 1 corresponding to the discharging trough 2, a horizontal winding rod 3 is rotatably installed between the inner walls on both sides of the winding rod 3, one end of the winding rod 3 extends out of the mounting frame 4, and a vertical turning handle 5 is fixedly connected to the end of the winding rod 3 extending out of the mounting frame 4, a sealing cover 6 is movably installed on the top of the work box 1, a drying device 7 for drying synthetic leather is fixedly installed between the inner walls on both sides of the work box 1, a feeding device 8 is fixedly installed on the work box 1 on the side away from the mounting frame 4, the end of the feeding device 8 extends into the work box 1, and a wiper mechanism is arranged in the feeding device 8.

[0025] Furthermore, the wiper mechanism includes a rotating shaft 10, a scraper 11 and a fixed plate 12. The rotating shaft 10 is fixedly installed between the inner walls on both sides of the feeding device 8, and the scraper 11 is rotatably sleeved on the rotating shaft 10. The fixed plates 12 are fixedly installed on the side edges of the inner walls on both sides of the feeding device 8 corresponding to the scraper 11. First, the end of the synthetic leather is passed through the bottom end of the scraper 11 in the feeding device 8. At this time, due to the passage of the synthetic leather, the bottom end of the scraper 11 slides on the upper surface of the synthetic leather due to the thickness of the scraper 11, so that the scraper 11 rotates on the rotating shaft 10 and becomes inclined to one side.

[0026] Furthermore, the wiper mechanism also includes a tension spring 15, a ring buckle 16 and a ring buckle 2 17. Two groups of mutually symmetrical ring buckles 16 are welded near the two sides of the scraper 11, and a ring buckle 2 17 is welded on the side of the fixed plate 12 corresponding to the side of the ring buckle 16. The tension spring 15 is sleeved between the ring buckle 16 and the ring buckle 2 17. When the scraper 11 tilts to one side, it drives the ring buckle 16 to pull the tension spring 15 to extend and lengthen. The end of the ring buckle 2 17 on the fixed plate 12 that is sleeved with the tension spring 15 provides a fixing effect for the tension spring 15. At this time, the synthetic leather continues to pass through the bottom end of the fixed plate 12 until it passes through the feeding device 8 and then passes through the drying device 7 to enter the discharge trough 2, and then the end of the synthetic leather is wound on the winding roller 3, and the winding roller 3 is driven to rotate by turning the handle 5 so that the synthetic leather is wrapped on the winding roller 3.

[0027] Furthermore, a water collecting trough 9 extending to the bottom end of the feeding device 8 is fixedly provided on the inner wall of the bottom of the feeding device 8 corresponding to the side of the scraper 11. When the winding rod 3 rotates, the synthetic leather is in a sliding state in the working box 1. When the synthetic leather slides, the buckle 16 connected by the tension spring 15 provides a unidirectional force for the scraper 11, so that the scraper 11 is tilted only when the synthetic leather passes through and the bottom end of the scraper 11 is squeezed by the synthetic leather. The bottom end of the scraper 11 slides on the synthetic leather to provide a wiping effect for it. During the wiping process, water is discharged into the water collecting trough 9 through the gap between the feeding device 8 and the scraper 11 for recycling and reuse.

[0028] Furthermore, a horizontal limit rod 13 is fixedly installed on the side of the fixed plate 12 corresponding to the ring buckle 17, and an integrated limit baffle 14 is fixedly provided on the end of the limit rod 13 away from the fixed plate 12. The side of the limit baffle 14 away from the limit rod 13 is in contact with the side of the scraper 11. The limit baffle 14 on the limit rod 13 provides support for the scraper 11 when the device stops using, to prevent the scraper 11 from flipping over due to the tension generated by the tension spring 15 pulling the ring buckle 16.

[0029] Working principle: First, the end of the synthetic leather is passed through the bottom end of the scraper 11 in the feeding device 8. At this time, due to the passing of the synthetic leather, the bottom end of the scraper 11 slides on the upper surface of the synthetic leather due to the thickness of the scraper 11, so that the scraper 11 rotates on the rotating shaft 10 and becomes inclined to one side. While the scraper 11 is inclined to one side, it drives the buckle 16 to pull the tension spring 15 to extend and lengthen. The buckle 2 17 on the fixed plate 12 and the end of the tension spring 15 that is sleeved provide a fixing effect for the tension spring 15. At this time, the synthetic leather continues to pass through the bottom end of the fixed plate 12 until it passes through the feeding device 8 and then passes through the drying device 7 to enter the discharge trough 2, and then the end of the synthetic leather is wound on the winding roller 3, and the handle 5 is driven by rotating the handle 5. The winding roller 3 rotates to wrap the synthetic leather around the winding roller 3. While the winding roller 3 rotates, the synthetic leather is in a sliding state in the working box 1. While the synthetic leather slides, the ring buckle 16 connected to the tension spring 15 provides a unidirectional force for the scraper 11, so that the scraper 11 is only squeezed by the synthetic leather when the synthetic leather passes through the bottom end of the scraper 11. The scraper 11 becomes inclined, and the bottom end of the scraper 11 slides on the synthetic leather to provide it with a wiping effect. During the wiping process, water is discharged into the sump 9 through the gap between the feeding device 8 and the scraper 11 for recycling and reuse. At the same time, the limit baffle 14 on the limit rod 13 provides support for the scraper 11 when the device stops using, to prevent the scraper 11 from flipping over due to the tension generated by the tension spring 15 pulling the ring buckle 16.
