Description

Technical Field

[0001] The present invention relates to the field of waterproof wool fabric production, and particularly to an apparatus and method for producing waterproof wool fabric by a film laminating method. Background Art

[0002] The production of waterproof wool fabric by the film laminating method mainly involves thermally pressing and laminating a transparent plastic film onto the surface of the wool fabric to form a protective film, thereby achieving the waterproof effect. The specific process steps may include: selecting a suitable biomass TPU film as the laminating material; using an environmentally friendly PUR glue for gluing and laminating operations, and antibacterial and mildew-proofing aids can be added to the glue to enhance the fabric properties; through the hot pressing and laminating technology, the film and the wool fabric are tightly combined to form a waterproof and breathable laminated wool fabric. The fabric produced by this process not only has waterproof function, but also has the advantages of breathability, antibacterial property, mildew resistance, etc., and is suitable for a variety of high-demand waterproof fields. The waterproof wool fabric produced by the film laminating method not only retains the natural advantages of wool, but also endows it with new functional characteristics, meeting the market demand for high-performance fabrics.

[0003] Chinese patent document with the application number CN202121778308.0 discloses "a film laminating device for waterproof polyester fabric, belonging to the technical field of fabric laminating equipment; by setting a glue coating roller, when the PU film passes through the glue coating roller, a layer of adhesive is evenly coated on the PU film by the glue coating roller, which can effectively increase the adhesion effect between the PU film and the polyester fabric. By setting four lifting cylinders, the extension and retraction of the four lifting cylinders are used to drive the lifting rod to move up and down, and when moving downward, the PU film is extruded to make the PU film and the polyester fabric fit more tightly, preventing phenomena such as non-waterproof and wrinkle resistance in the overall laminated polyester fabric."

[0004] However, in the above solution, only the tight fit between the PU film and the polyester fabric can be achieved through extrusion, thereby improving the quality after lamination. However, it uses single-layer glue coating and is coated by a glue coating roller. When laminating wool fabric, due to the soft characteristics of the surface of the wool fabric, single-layer glue coating cannot well achieve the firm adhesion between the wool fabric and the waterproof material film. In the existing lamination, for the use of glue, spraying is usually adopted, and the specific nozzle position is fixed, resulting in a fixed spraying position. In order to avoid spraying dead corners, sufficient redundant spraying needs to be arranged, which will cause waste of glue during spraying. If the gaps between the glue spraying points are too large, there will be dead corners in some positions and effective spraying cannot be formed. After bonding in the later stage, gaps without glue will be formed, which will seriously reduce the bonding quality and the durability of subsequent use. Therefore, an apparatus and method for producing waterproof wool fabric by a film laminating method are proposed. Summary of the Invention

[0005] The object of the present invention is to provide a device and method for producing a waterproof wool fabric by a film laminating method, which solves the problems in the existing film laminating methods that the glue coating is generally single-layer, so that effective bonding cannot be carried out when laminating the waterproof wool, and the fixed glue spraying points will result in glue spraying dead angles and reduce the bonding quality.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] Embodiment 1:

[0029] Please refer to Figure 1-7 , the present invention provides a technical solution: a device for producing waterproof wool fabric by the film laminating method, including a support frame 1, and a waterproof film roller 2, a wool fabric roller 4, a bonding hot press roller 6, and a traction roller 7 provided on the support frame 1. The traction roller 7 is used to traction the film on the waterproof film roller 2 and the fabric on the wool fabric roller 4 through the bonding hot press roller 6 and perform hot press lamination. Slide carriages 10 are slidably installed on both opposite sides of the support frame 1. An upper active guide roller 13 and a lower active guide roller 14 with parallel axes are rotatably installed between the two slide carriages 10, and a glue spraying mechanism is provided. The glue spraying mechanism is used to synchronously spray the two bonding surfaces of the film and the fabric, and a transmission mechanism is connected between the upper active guide roller 13 and the lower active guide roller 14 and the glue spraying mechanism, which is used to drive the glue spraying mechanism to reciprocate when the upper active guide roller 13 and the lower active guide roller 14 rotate.

[0030] Two upper and lower power motors one are also installed on the support frame 1, and the output ends of the two upper and lower power motors one are axially fixedly installed with the waterproof film roller 2 and the wool fabric roller 4 respectively. A power motor two is also installed on the support frame 1, and the output end of the power motor two is axially fixedly installed with the bonding hot press roller 7. Thus, through the setting of the power motor one, the driving rotation of the waterproof film roller 2 and the wool fabric roller 4 can be realized.

[0031] Moreover, a second power motor can also be installed on multiple traction rollers 7 to achieve active rotation of the traction rollers 7, so as to actively traction the waterproof PU film 32 and the wool fabric 33 passing through the upper and lower bonding and hot-pressing rollers 6. Or the traction rollers 7 have no power, and a winding device is arranged at the rear end to wind the waterproof PU film 32 and the wool fabric 33 passing through the upper and lower bonding and hot-pressing rollers 6. At this time, the traction rollers 7 are driven to rotate passively.

[0032] Whether the first power motor and the second power motor are specifically set can also be configured according to the overall power of the device.

[0033] An upper passive guide roller 3 and a lower passive guide roller 5 for supporting the film and the fabric are also installed on the support frame 1. And according to the attached Figure 4 specification, the settings of the upper passive guide roller 3 and the lower passive guide roller 5 can respectively provide upward tension for the upper-side film and downward tension for the downward fabric, so as to ensure the tension of the film and the fabric during the transmission process.

[0034] The glue spraying mechanism includes a connecting plate 19, a sliding box 20, a limiting slider 22, and a glue spraying head 24. The connecting plate 19 is connected to the sliding frame 10, the sliding box 20 is connected to the connecting plate 19, and sliding rails 21 are opened on both the upper and lower sides of the sliding box 20. The limiting slider 22 slides in the sliding rails 21, and a sliding bar 23 is connected to the outside of the limiting slider 22 in the sliding rails 21. The glue spraying heads 24 are installed at equal intervals on the sliding bar 23, so that the glue spraying heads 24 installed on the sliding bars 23 sliding on both the upper and lower sides of the sliding box 20 can respectively spray glue towards the upper active guide roller 13 on the upper side and the lower active guide roller 14 on the lower side. Then, when there is a film passing between the upper glue spraying head 24 and the upper active guide roller 13 and a fabric passing between the lower glue spraying head 24 and the lower active guide roller 14, the upper and lower glue spraying heads 24 can synchronously spray glue on the adjacent surfaces of the film and the fabric in two directions, so as to achieve double-sided glue spraying.

[0035] A plurality of third power motors 15 are also installed on the outside of the sliding frame 10. The output ends of the respective third power motors 15 are respectively connected to the upper active guide roller 13 and the lower active guide roller 14. The setting of the third power motors 15 can provide the power for the active rotation of the upper active guide roller 13 and the lower active guide roller 14.

[0036] The transmission mechanism includes a large pulley 16, a small pulley 17, a guiding slide bar 25, and a limiting plate 26. The large pulley 16 is respectively sleeved at both ends of the upper active guide roller 13. The small pulley 17 is rotatably connected to the carriage 10, and a cam 18 is coaxially connected to the small pulley 17. A belt 29 is also jointly sleeved between the large pulley 16 and the small pulley 17. The guiding slide bar 25 slidably penetrates through the connecting plate 19, and limiting plates 26 that limit the connecting plate 19 are fixedly connected to both ends. Rotating plates 28 are rotatably connected between the opposite ends of the sliding strips 23 on the upper and lower sides and the limiting plates 26 on their respective sides. Each cam 18 is in sliding contact with the surface of the connecting plate 19 on its respective side.

[0037] A spring 27 is sleeved on the outer side of the guiding slide bar 25 above the connecting plate 19, and both ends of the spring 27 are respectively connected to the connecting plate 19 and the limiting plate 26. In this way, when the upper active guide roller 13 and the lower active guide roller 14 are driven to rotate actively, the small pulley 17 can also be driven to rotate by the belt 29, and then the cam 18 thereon can be rotated, so as to realize the sliding push of the cam 18 on the limiting plates 26 above the connecting plates 19 on both sides. And in this process, the cams 18 on both sides are symmetrically arranged up and down. Therefore, when one cam 18 is at the highest position, the other cam 18 is at the lowest position. In this way, the extrusion force of the cam 18 at the highest position on the limiting plate 26 is the smallest. Under the action of the spring 27 thereon, the limiting plate 26 will also drive the guiding slide bar 25 to move to a high position, while the guiding slide bar 25 on the other side moves to a low position in the opposite direction. And in this movement process, the sliding strips 23 on the upper and lower sides can also be pulled to slide in the opposite direction through the rotating plates 28. Repeating this way forms a reciprocating movement in the opposite direction of the sliding strips 23 on the upper and lower sides, enabling the position of the glue spraying head 24 to be adjusted within a certain range, improving the comprehensiveness of glue spraying without leaving dead corners, and also improving the bonding firmness, thereby improving the durability.

[0038] The guiding slide bars 25 slidably sleeved on each connecting plate 19 are grouped in pairs, which can ensure the stability of the limiting plate 26 sliding on the connecting plate 19 through the guiding slide bars 25.

[0039] A slide rail 9 is also installed on the support frame 1. Sliders 12 are fixedly connected to both sides of the carriage 10. Each slider 30 slides in the slide rail 9 on its respective side. An electric cylinder 11 is fixedly installed in the slide rail 9, and the output end of the electric cylinder 11 is connected to the slider 12. In this way, the slider 12 can be pushed to slide in the slide rail 9 through the electric cylinder 11, so as to adjust the position of the carriage 10, and further adjust the different tensions between the upper active guide roller 13 and the lower active guide roller 14 on the film and the fabric, so as to realize different degrees of tensioning of the film and the fabric.
