Description

Technical Field

[0001] This utility model relates to the field of microfiber leather processing technology, specifically a waterproof coating device for microfiber leather fabric processing. Background Technology

[0002] Microfiber leather is widely used in many industries due to its advantages such as wear resistance, breathability, and texture similar to genuine leather. However, untreated microfiber leather has limited waterproof performance and needs to be laminated with a waterproof membrane on its surface to meet usage requirements.

[0003] Traditional waterproof laminating devices for microfiber leather fabric processing are not convenient for adjusting the tension of microfiber leather fabric and waterproof membrane during transportation. Microfiber leather fabric and waterproof membrane are prone to wrinkling due to insufficient tension or stretching and deformation due to excessive tension during transportation, which affects subsequent laminating operations. Therefore, we need to propose a waterproof laminating device for microfiber leather fabric processing. Utility Model Content

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A waterproof laminating device for processing microfiber leather fabric includes: a base plate 1, on which two sets of guide mechanisms 2 are symmetrically arranged for guiding the fabric and waterproof membrane; a tension adjusting mechanism 3, located between the two sets of guide mechanisms 2 on the base plate 1, for adjusting the tension between the fabric and the waterproof membrane, the tension adjusting mechanism 3 including a support frame 31, a drive assembly 32, two sets of connecting plates 33 and two sets of adjusting rollers 34, the drive assembly 32 drives the two sets of connecting plates 33 to rise and fall, thereby changing the height of the two sets of adjusting rollers 34; a feeding mechanism 4, located on the top of the base plate 1 and on one side of the two sets of guide mechanisms 2, for conveying the fabric and waterproof membrane; and a laminating mechanism 5, located on one side of the base plate 1 and on the feeding mechanism 4, for adhering the waterproof membrane to the surface of the fabric.

[0029] In this embodiment, the drive component 32 drives the two sets of connecting plates 33 to rise and fall, thereby adjusting the height of the two sets of adjusting rollers 34. With the cooperation of the two sets of guiding mechanisms 2, the tension of the conveyed microfiber leather fabric and waterproof membrane can be adjusted to avoid wrinkles or deformation of the microfiber leather fabric and waterproof membrane due to poor tension adjustment, thus ensuring the subsequent lamination operation.

[0030] The drive assembly 32 includes a connecting frame 321, a threaded rod 322, a first drive motor 323, and a lifting plate 324. The connecting frame 321 is fixedly installed on the inner top of the support frame 31. The threaded rod 322 is rotatably installed inside the connecting frame 321, and one end of the threaded rod 322 passes through the support frame 31 and is fixedly connected to the first drive motor 323. The lifting plate 324 is threadedly connected to the outer wall of the threaded rod 322, and the bottom of the lifting plate 324 is fixedly connected to two sets of connecting plates 33.

[0031] In this embodiment, the output end of the first drive motor 323 drives the threaded rod 322 to rotate, causing the lifting plate 324 to rise and fall. The lifting plate 324 drives the two sets of connecting plates 33 connected to it to rise and fall. The two sets of connecting plates 33 can drive the two sets of adjusting rollers 34 to rise and fall, changing the height of the two sets of adjusting rollers 34.

[0032] Both sides of the connecting frame 321 are provided with limiting grooves that are compatible with the lifting plate 324. The lifting plate 324 can be lifted and installed inside the two sets of limiting grooves.

[0033] In this embodiment, the lifting plate 324 can be limited by two sets of limiting grooves, so that the lifting plate 324 can be raised and lowered when the threaded rod 322 rotates;

[0034] Both sides of the support frame 31 are provided with through slots, and two sets of connecting plates 33 are respectively set inside the two sets of through slots. The opposite sides of the two sets of connecting plates 33 are respectively rotatably connected to the two ends of the two sets of adjusting rollers 34.

[0035] In this embodiment, the two ends of the lifting plate 324 are respectively located inside the two sets of through slots. When the lifting plate 324 is raised and lowered, it will drive the two sets of connecting plates 33 to be raised and lowered inside the two sets of through slots respectively. Since the opposite sides of the two sets of connecting plates 33 are respectively rotatably connected to the two ends of the two sets of adjusting rollers 34, the two sets of adjusting rollers 34 can be driven to be raised and lowered.

[0036] The guiding mechanism 2 includes two sets of support plates 21, a fabric roller 22 and a film roller 23. The two sets of support plates 21 are symmetrically fixedly installed at the bottom of the base plate 1. The film roller 23 is rotatably installed on the opposite side of the two sets of support plates 21. The fabric roller 22 is rotatably installed on the two sets of support plates 21 located directly below the film roller 23.

[0037] In this embodiment, the waterproof membrane passes above a set of membrane rollers 23, then below a set of upper adjusting rollers 34, and then above another set of membrane rollers 23. The microfiber leather fabric passes above a set of fabric rollers 22, then below a set of lower adjusting rollers 34, and then above another set of fabric rollers 22, forming a U-shaped conveying route. The tension of the conveyed microfiber leather fabric and waterproof membrane can be adjusted by adjusting the height of the two sets of adjusting rollers 34.

[0038] The feeding mechanism 4 includes two sets of mounting frames 41, four sets of upper feeding rollers 42 and four sets of lower feeding rollers 43. The four sets of upper feeding rollers 42 are equidistantly rotated and installed on opposite sides of the two sets of mounting frames 41. The four sets of lower feeding rollers 43 are rotatably installed on the two sets of mounting frames 41 located directly below the four sets of upper feeding rollers 42.

[0039] In this embodiment, the waterproof membrane passes through the bottom of four sets of upper feeding rollers 42, while the microfiber leather fabric passes through the top of four sets of lower feeding rollers 43, so that the waterproof membrane and the microfiber leather fabric move in parallel and the distance between the waterproof membrane and the microfiber leather fabric is reduced, making it easier to perform the coating operation.

[0040] The film coating mechanism 5 includes two sets of vertical plates 51, an upper film coating roller 52, a lower film coating roller 53, a second drive motor 54, a drive gear 55, and a driven gear 56. The upper film coating roller 52 and the lower film coating roller 53 are rotatably mounted on opposite sides of the two sets of vertical plates 51 in an up-down manner. One end of the upper film coating roller 52 passes through one set of vertical plates 51 and is fixedly connected to the second drive motor 54. The other ends of the upper film coating roller 52 and the lower film coating roller 53 both pass through the other set of vertical plates 51 and are respectively connected to the drive gear 55 and the driven gear 56. The drive gear 55 and the driven gear 56 mesh with each other.

[0041] In this embodiment, the output of the second drive motor 54 drives the upper coating roller 52 to rotate. The upper coating roller 52 drives the connected drive gear 55 to rotate, and the drive gear 55 drives the driven gear 56 meshing with it to rotate, thereby causing the lower coating roller 53 to also rotate. The rotation directions of the upper coating roller 52 and the lower coating roller 53 are opposite. The waterproof membrane and microfiber leather fabric are conveyed between the upper coating roller 52 and the lower coating roller 53, and the upper coating roller 52 presses the waterproof membrane onto the surface of the microfiber leather fabric. Specifically, the upper coating roller 52 is a heated roller.

[0042] A feeding plate 6 is fixedly connected to one side of the two sets of vertical plates 51. The feeding plate 6 is inclined. Multiple sets of auxiliary feeding wheels 7 are rotatably installed on the side of the feeding plate 6 near the film-coating roller 53. The top of the auxiliary feeding wheels 7 is located below the film-coating roller 53.

[0043] In this embodiment, the coated fabric is discharged through the feed plate 6 and comes into contact with the auxiliary feed roller 7. The auxiliary feed roller 7 assists in feeding and ensures the movement of the fabric.

[0044] In this embodiment, the first drive motor 323 can be a 42BYGH48-1684A stepper motor, the second drive motor 54 can be a Y80M1-2 three-phase asynchronous motor, and the coating roller 52 can be a JR-GR-200 stainless steel heating roller. The first drive motor 323, the second drive motor 54, and the coating roller 52 are all finished products in the prior art. Their working principles, installation methods, and wiring connection methods can be learned from the purchased manual, and will not be described in detail here.

[0045] Working principle: In this invention, the waterproof membrane passes above a set of membrane rollers 23, then below a set of upper adjusting rollers 34, and then above another set of membrane rollers 23. The microfiber leather fabric passes above a set of fabric rollers 22, then below a set of lower adjusting rollers 34, and then above another set of fabric rollers 22, forming a U-shaped conveying route. By adjusting the height of the two sets of adjusting rollers 34, the tension of the conveyed microfiber leather fabric and waterproof membrane can be adjusted. Then, the waterproof membrane passes under the four sets of upper feeding rollers 42, and the microfiber leather fabric passes under the four sets of lower feeding rollers 43, so that the waterproof membrane and the microfiber leather fabric move parallel to each other and reduce the distance between them. Finally, the waterproof membrane is pressed onto the surface of the microfiber leather fabric by the laminating mechanism 5.

[0046] 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.
