Abstract
Description
Technical Field
[0001] This utility model relates to the field of nonwoven fabric thermal rolling coating technology, specifically to a composite nonwoven fabric thermal rolling coating device. Background Technology
[0002] The composite nonwoven fabric hot rolling coating device is a device used to bond nonwoven fabric with plastic film or aluminized film by hot pressing to form a composite material with special properties.
[0003] Existing nonwoven fabric laminating equipment generally includes nonwoven fabric rollers and aluminized film rollers. Generally, the aluminized film rollers are set above the nonwoven fabric rollers. During hot rolling, the nonwoven fabric and the aluminized film will enter the hot rolling mechanism at the same time. The nonwoven fabric and the aluminized film will be laminated together by high temperature and extrusion. Then, the laminated nonwoven fabric will be wound up by the winding rollers.
[0004] However, in existing hot-rolling composite equipment, the aluminized film is generally hot-rolled directly with the nonwoven fabric. Due to the large temperature difference, the surface of the aluminized film may experience stress concentration due to sudden heating, leading to cracks or peeling of the aluminized layer and affecting the overall quality of the composite material. During the hot-pressing process, the bonding force between the aluminized film and the nonwoven fabric may be uneven due to their different coefficients of thermal expansion, resulting in localized weak bonding and reducing the durability and reliability of the product. Furthermore, after hot rolling, there is usually some nonwoven fabric damaged during hot rolling on both sides of the composite nonwoven fabric, which requires subsequent cutting of the composite nonwoven fabric roll, making the processing steps quite complicated. Utility Model Content
[0005] The technical problem this invention aims to solve is that existing hot-rolling composite devices generally lack an aluminized film preheating structure, which easily affects the quality of the composite nonwoven fabric, reduces the product's durability and reliability, and also requires cutting the wound composite nonwoven fabric, making the processing steps rather cumbersome.
[0006] To solve the above problems, the technical solution adopted by this utility model is a composite nonwoven fabric hot rolling coating device, including a frame structure, on which nonwoven fabric and aluminized film are mounted, a hot rolling mechanism is provided in the middle of the frame structure, a take-up roller is provided at one end of the frame structure, a preheating structure is provided in the middle of the frame structure, the preheating structure includes a steam heating pipe fixed to the frame structure, the two ends of the steam heating pipe are respectively connected to a steam inlet and a steam outlet, a heat conduction pipe is rotatably provided on the outside of the steam heating pipe, a cutting mechanism is provided next to the hot rolling mechanism, the cutting mechanism includes a support plate fixed in the frame structure, a pair of cutting blades are fixed on the upper side of the support plate, a waste fabric take-up roller is provided below the support plate in the frame structure, and one end of the aluminized film passes around the heat conduction pipe, passes through the hot rolling mechanism and combines with the nonwoven fabric.
[0007] As a further embodiment of this invention: both the steam inlet and the steam outlet are connected to an external steam generator to facilitate the introduction of high-temperature steam into the steam heating pipe for preheating the aluminum-coated film.
[0008] As a further embodiment of this utility model: a motor is fixed to one end of the winding roller, a motor is fixed to one end of the waste cloth winding roller, and the hot rolling mechanism, motor one, and motor two are all electrically connected to an external power source.
[0009] As a further embodiment of this invention, the distance between a pair of cutting blades is equal to the width of the aluminized film, so as to facilitate timely cutting of the nonwoven fabric with tears on both sides after lamination.
[0010] As a further embodiment of this utility model: the aluminum-coated film and the non-woven fabric are hot-pressed together and wrapped around the outside of the winding roller, which can collect the composite non-woven fabric.
[0011] As a further embodiment of this invention: the non-woven fabric cut off by the cutting blade is wound around the outside of the waste fabric take-up roller to facilitate the collection of non-woven fabric waste.
[0012] Compared with the prior art, the advantages of this utility model are as follows: This application adds a preheating structure, which can preheat the aluminized film by adding a steam heating pipe, so that the aluminized film can be better thermally rolled and laminated with the nonwoven fabric; it adds a cutting structure, which can cut the damaged fabric on both sides of the composite nonwoven fabric in time, eliminating the need for subsequent cutting and saving processing time.

[0022] This utility model provides a technical solution to address the existing problems mentioned in the background art.
[0023] Combined with appendix Figure 1 , 2 4. It can be seen that the machine includes a frame structure 1, on which a non-woven fabric 2 and an aluminized film 3 are mounted. A hot rolling mechanism 4 is located in the middle of the frame structure 1. A take-up roller 5 is located at one end of the frame structure 1, which can collect the composite non-woven fabric. A preheating structure is located in the middle of the frame structure 1. The preheating structure includes a steam heating pipe 6 fixed to the frame structure 1, which can preheat the aluminized film 3. The two ends of the steam heating pipe 6 are respectively connected to a steam inlet 6.1 and a steam outlet. A heat-conducting pipe 7 is rotatably provided on the outside of the steam heating pipe 6. The steam inlet 6.1 and the steam outlet are both connected to an external steam generator, so as to introduce high-temperature steam into the steam heating pipe 6, so as to preheat the aluminized film 3. The aluminized film 3 and the non-woven fabric 2 are hot-pressed composite fabric wrapped around the outside of the take-up roller 5, which can collect the composite non-woven fabric.
[0024] Combined with appendix Figure 1 , 35. It can be seen that a cutting mechanism is provided next to the hot rolling mechanism 4, which can cut the damaged non-woven fabric in time. The cutting mechanism includes a support plate 8 fixed in the frame structure 1. A pair of cutting blades 9 are fixed on the upper side of the support plate 8. The distance between the pair of cutting blades 9 is equal to the width of the aluminized film 3, so as to cut the damaged non-woven fabric on both sides of the composite non-woven fabric in time. A waste fabric take-up roller 10 is provided below the support plate 8 in the frame structure 1. One end of the aluminized film 3 passes around the heat conduction pipe 7, passes through the hot rolling mechanism 4 and combines with the non-woven fabric 2. The non-woven fabric 2 cut by the cutting blades 9 is wrapped around the outside of the waste fabric take-up roller 10 to collect the non-woven fabric waste. A motor 11 is fixed at one end of the take-up roller 5, and a motor 22 is fixed at one end of the waste fabric take-up roller 10. The hot rolling mechanism 4, motor 11, and motor 22 are all electrically connected to an external power source.
[0025] The working principle of this application is as follows: When processing composite nonwoven fabric, the nonwoven fabric 2 and the aluminized film 3 are first placed on the frame structure 1, and then one end of them is extended into the hot rolling mechanism 4 for hot rolling composite. Then, the cutting blade 9 cuts off the damaged nonwoven fabric, and then the composite nonwoven fabric is rolled on the outside of the winding roller 5. The cut nonwoven fabric is then rolled on the outside of the waste fabric winding roller 10. Then, the motor 11 and the motor 2 12 can be started to drive the winding roller 5 and the waste fabric winding roller 10 to rotate, so as to continuously carry out the film coating process of composite nonwoven fabric.
[0026] During processing, the steam inlet 6.1 and the steam outlet need to be connected to an external steam generator so that high-temperature steam can be introduced into the steam heating pipe 6 to preheat the aluminized film 3 and ensure the quality of the non-woven fabric coating.
