Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric coating and pressing equipment, and more specifically, to a coating and flattening device for a waterproof high-strength composite nonwoven fabric production line. Background Technology

[0002] Nonwoven fabric is a sheet-like structural material composed of oriented or randomly arranged fibers. The simplest way to prepare nonwoven fabrics with multiple functions is to first produce layered structures with different functions, and then use a laminating and pressing equipment to press several layers together to form the final nonwoven fabric.

[0003] In the above process, after several layers of structure are pressed together, the nonwoven fabric needs to be cooled by air to facilitate winding. For example, Chinese patent with publication number CN214563053U describes a direct-blowing air cooling method. This air cooling method can only act on one surface layer of the nonwoven fabric. When the nonwoven fabric has a waterproof function, unilateral air cooling cannot effectively act on the other side. Although the thickness of the nonwoven fabric is not large, it will still reduce the air cooling efficiency. In severe cases, it will cause the uncured nonwoven fabric adhesive layer to deform, resulting in wrinkles when the nonwoven fabric is wound. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a film-coating and flattening device for a waterproof high-strength composite nonwoven fabric production line. The technical problem to be solved by the present invention is: how to ensure that both sides of the waterproof nonwoven fabric can be cooled by air during the air-cooling process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof high-strength composite nonwoven fabric production line laminating and flattening device, including a pressing component; an air-cooling component, including an upper cover plate, a lower cover plate, a pipe opening, and an exhaust port, wherein the upper cover plate and the lower cover plate are spliced ​​into an annular ring, the pipe opening and the exhaust port are opened on the same side of the annular ring, the nonwoven fabric output from the pressing component passes through the annular ring and is wound up by a take-up roller, the pipe opening and the exhaust port are respectively located on the upper and lower sides of the nonwoven fabric, the pipe opening is connected to the output end of the air pump through a pipe, and the air pump is electrically connected to an external controller.

[0006] In a preferred embodiment, both the upper and lower cover plates are provided with guide channels, and several guide plates are connected alternately in the guide channels. The guide plates are used to guide the airflow to the upper and lower end faces of the nonwoven fabric.

[0007] In a preferred embodiment, magnets are embedded in the guide plates on the upper and lower sides of the nonwoven fabric, and the magnets on the upper and lower sides are magnetically attracted to each other.

[0008] In a preferred embodiment, the upper cover plate has a placement groove in which a magnetic block is placed. The magnetic block has the same magnetism as the magnet in the guide plate located on the upper cover plate.

[0009] In a preferred embodiment, the upper cover plate has a placement groove, a bolt passes through the placement groove and is threadedly connected to the placement groove, and the bolt abuts against the corresponding guide plate.

[0019] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of this disclosure will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0020] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more exemplary embodiments. Numerous specific details are provided in the following description to give a full understanding of exemplary embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more of the specific details omitted, or other methods, components, steps, etc., can be employed. In other instances, well-known structures, methods, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0021] Example 1

[0022] like Figure 1 , Figure 2 and Figure 4 A film-coating and flattening device for a waterproof and high-strength composite nonwoven fabric production line includes a pressing component 1 and an air-cooling component 2.

[0023] The pressing component 1 includes a first pressing roller 11, a second pressing roller 12, and a support 13. The support 13 is placed on the ground, and the first pressing roller 11 and the second pressing roller 12 are rotatably connected to the support 13. The first pressing roller 11 and the second pressing roller 12 are connected by a transmission. The nonwoven fabric enters the air-cooling component 2 for air cooling after being hot-pressed on both sides by the first pressing roller 11 and the second pressing roller 12. A motor is provided on one side of the pressing component 1 to drive the first pressing roller 11 and the second pressing roller 12 to rotate in opposite directions. Since the means of controlling the first pressing roller 11 and the second pressing roller 12 by motor is mature and has been applied in various hot pressing equipment, it will not be described in detail in this embodiment.

[0024] The air-cooled component 2 includes an upper cover plate 21, a lower cover plate 22, a guide channel 23, a guide plate 24, a pipe opening 25, and an exhaust port 26. The upper cover plate 21 and the lower cover plate 22 are spliced ​​together by bolts and fasteners to form a ring that runs through opposite sides. Non-woven fabric is inserted into the air-cooled component 2 from one side and exited from the other side, and then collected by the take-up roller.

[0025] A pipe 25 is fixed on one side of the upper cover plate 21. The pipe 25 is connected to the output end of the air pump through a pipe. An external controller electrically connected to it controls the air pump to blow out cold air. The cold air enters the internal space of the upper cover plate 21 and the lower cover plate 22. The exhaust port 26 is opened on the lower cover plate 22. The pipe 25 and the exhaust port 26 are located on the same side and are located on the upper and lower sides of the non-woven fabric, respectively. In this way, the cold air is passed through the upper layer of the non-woven fabric by the air pump, turns at the connection point of the upper cover plate 21 and the lower cover plate 22 and passes through the lower end of the non-woven fabric, and is then blown out from the exhaust port 26, forming an airflow recirculation to cool both the upper and lower sides of the non-woven fabric.

[0026] Preferably, the connection between the upper cover plate 21 and the lower cover plate 22 is a rounded transition.

[0027] Preferably, fabric curtains are fixed on both sides of the opening surfaces of the upper cover plate 21 and the lower cover plate 22 to reduce the proportion of airflow overflowing from the openings.

[0028] Example 2

[0029] like Figure 1 , Figure 2 and Figure 4 Based on the above embodiments, both the upper cover plate 21 and the lower cover plate 22 are provided with guide channels 23 along the airflow direction. The guide channels 23 are interleaved with raised guide plates 24, which are used to guide the airflow to the non-woven fabric layer to improve the air cooling effect.

[0030] Magnets are embedded in the guide plates 24 on both the upper and lower sides of the nonwoven fabric, and the magnets are magnetically attracted to each other. When the upper cover plate 21 and the lower cover plate 22 are spliced ​​together, the magnetic attraction will act on the guide plates 24 on both sides, so that the guide plates 24 on both sides are as close as possible, so as to guide some airflow onto the nonwoven fabric layer.

[0031] Several placement slots are provided on the surface of the upper cover plate 21, and drive components are provided in the slots to control the upper and lower guide plates 24 to move closer or further apart.

[0032] Preferably, the driving component is a magnetic block, and the magnetic properties of the magnetic block are the same as those of the magnet in the guide plate 24 located on the upper cover plate 21. Through the action of magnetic repulsion, the guide plates 24 on the upper and lower sides are further brought closer to each other.

[0033] Preferably, the driving component is a bolt, which passes through the upper cover plate 21 and is threadedly connected to the upper cover plate 21. By tightening the bolt, the bolt presses against the corresponding guide plate 24, thereby bringing the guide plates 24 on the upper and lower sides closer together.

[0034] In both of the above preferred embodiments, magnetic repulsion or extrusion is applied to the guide plate 24, allowing the guide plate 24 to further overcome its own deformation recovery force, thereby allowing the upper and lower guide plates 24 to get closer together and guide the airflow to the non-woven fabric layer.

[0035] Example 3

[0036] like Figure 3 Based on Embodiment 1 or Embodiment 2, a support member 3 is also provided.

[0037] The support member 3 includes an arm plate 31 and support wheels 32. The arm plate 31 is installed in the middle of the connecting surface of the upper cover plate 21 and the lower cover plate 22. Two support wheels 32 are rotatably connected to the arm plate 31. The non-woven fabric can pass through the two support wheels 32. Through the support and transmission action of the two support wheels 32, the non-woven fabric can move more stably in the air-cooled component 2.

[0038] Furthermore, a limiting ridge is fixed on the arm plate 31, and limiting grooves are opened on the upper cover plate 21 and the lower cover plate 22. The limiting ridge can be inserted into the limiting groove to improve the convenience of installing the arm plate 31 into the upper cover plate 21 and the lower cover plate 22.

[0039] Working principle of this utility model:

[0040] This application sets up a left-right through-enclosed structure, allowing cold air to be introduced into the air-cooling component 2 and then circulate around the inner wall of the air-cooling component 2 before being discharged. During the airflow circulation, both the upper and lower layers of the non-woven fabric located in the air-cooling component 2 can be cooled, and the air pressure on the upper and lower sides of the non-woven fabric is basically the same, which can reduce the probability of the non-woven fabric being deformed by wind.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
