Description

Technical Field

[0001] This utility model relates to the field of composite technology of membranes and nonwoven fabrics, and in particular to a thermal melt composite device for membranes and nonwoven fabrics. Background Technology

[0002] To achieve the composite of membrane and nonwoven fabric, the membrane and nonwoven fabric can be unwound and stacked, and then thermally melted together through hot press rollers to form a composite fabric.

[0003] In the prior art, utility model patent application number 2024204792827 discloses a hot melt adhesive web composite device for nonwoven fabrics. This device uses two hot press rollers to press and heat the hot melt adhesive web, melting it and then bonding the upper and lower layers of nonwoven fabric together to complete the composite process. Because the hot press rollers rotate to contact the nonwoven fabrics, the contact time is short. To transfer sufficient heat to the nonwoven fabrics and the hot melt adhesive web, the heating temperature of the hot press rollers needs to be relatively high, which is difficult to control. High temperatures can also easily cause the fibers on the surface of the nonwoven fabric to curl and deform, affecting the surface quality of the composite fabric.

[0004] In addition, after the hot-press roller presses and melts the hot melt adhesive web, the resulting hot melt joint is flat and has a very strong structure, making it difficult to separate the hot melt adhesive web from the nonwoven fabric. This affects the subsequent recycling of the composite fabric and requires improvement. Utility Model Content

[0005] The purpose of this invention is to provide a device for hot-melt lamination of membrane and nonwoven fabric, which enables hot-melt lamination of membrane and nonwoven fabric, ensures surface quality, and improves the convenience of separation and recycling.

Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 yes Figure 1 A schematic diagram of the structure after the lifting seat has descended. Detailed Implementation

[0016] The following is combined Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0017] like Figure 1 and Figure 2 The membrane and nonwoven fabric hot melt composite device shown includes: a base 1, a lifting seat 14, a floating pressure plate 9, and an ultrasonic heat sealing machine 19. The lifting seat 14 is movably mounted on the base 1. In this embodiment, a second guide rod 17 pointing downwards to the base 1 is provided at the bottom of the lifting seat 14, and a second guide sleeve 16 corresponding to the second guide rod 17 is provided on the base 1, which improves the lifting stability of the lifting seat 14.

[0018] A motor 12 is horizontally mounted on the base 1. An eccentric wheel 13 is mounted on the shaft of the motor 12, located below the lifting seat 14. The motor 12 can be intermittently rotated via a PLC controller, driving the eccentric wheel 13 to rotate intermittently. Figure 2As shown, the lifting seat 14 is driven to lift. In this embodiment, a bearing 11 is sleeved on the eccentric wheel 13, and the outer ring of the bearing 11 makes rolling contact with the bottom surface of the lifting seat 14, thereby reducing friction.

[0019] like Figure 1 As shown, the base 1 is provided with guide frames 2 located on both sides of the lifting seat 14. After the film 21 and non-woven fabric 20 are unwound, they are fed in through the guide frame 2 on one side, and after hot-melt bonding, they form a composite fabric 4, which is then sent out from the guide frame on the other side.

[0020] In this embodiment, the guide frame 2 is provided with two parallel guide rollers 3. The two guide rollers 3 can feed the membrane 21 and the non-woven fabric 20 located above and below the membrane 21 into the guide frame 2 together to achieve three-layer superposition composite.

[0021] A cover plate 5 is provided on the top of the guide frame 2, and the floating pressure plate 9 is provided below the cover plate 5. In this embodiment, a first guide rod 8 is provided on the floating pressure plate 9, which penetrates the cover plate 5 upward. A first guide sleeve 6 corresponding to the first guide rod 8 is provided in the cover plate 5. The floating pressure plate 9 is guided to rise and fall by the cooperation of the first guide rod 8 and the first guide sleeve 6.

[0022] In addition, the first guide rod 8 is provided with a nut 7 located above the cover plate 5 to limit the descent of the floating pressure plate 9 and adjust the lowest position height to accommodate the thickness of the film 21 and non-woven fabric 20 after they are stacked. The film 21 and non-woven fabric 20 pass through the bottom surface of the floating pressure plate 9 after they are stacked.

[0023] The ultrasonic heat sealing machines 19 are spaced apart on the lifting base 14 and located below the floating pressure plate 9. Six ultrasonic heat sealing machines 19 can be used, arranged in two rows at intervals. Each ultrasonic heat sealing machine 19 includes an ultrasonic generator 10 and a welding head 15. The welding head 15 is located on top of the ultrasonic generator 10. The lifting base 14 intermittently drives the ultrasonic heat sealing machine 19 to rise. By cooperating with the floating pressure plate 9, the welding head 15 provides point-distributed ultrasonic vibration energy to the membrane 21 and non-woven fabric 20, realizing local heat melting of the membrane 21 and performing composite bonding of the membrane 21 and non-woven fabric 20 to obtain composite fabric 4. Six heat-melting connection points are formed in the composite fabric 4 at intervals in one operation.

[0024] The spaced hot-melt connection points can ensure the stability and surface quality of the composite structure of membrane 21 and non-woven fabric 20, and can also be quickly torn apart after the composite fabric 4 is used, improving the convenience of separate recycling of membrane 21 and non-woven fabric 20, and are environmentally friendly.

[0025] In addition, a counterweight 18 is provided on the floating pressure plate 9. During the upward process of the welding head 15, it contacts the non-woven fabric 20 and transmits the upward force to the floating pressure plate 9. The counterweight 18 increases the weight of the floating pressure plate 9, thereby pressing down the film 21 and the non-woven fabric 20 to ensure the smooth operation of the ultrasonic heat sealing machine 19 and instantly complete the heat fusion bonding.

[0026] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
