Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to a nonwoven fabric processing roller coating device. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is composed of oriented or random fibers. It is called cloth because it has the appearance and some properties of cloth. Non-woven fabric has the characteristics of moisture resistance, breathability, flexibility, light weight, non-flammability, easy decomposition, rich colors, low price, and recyclability. For example, it is mostly made of polypropylene granules as raw material, which is produced by high temperature melting, spinning, laying, and hot pressing and winding in a continuous one-step process. Existing non-woven fabric coating machines include a fabric feeding device, a heating coating device, a cooling device, a fabric taking device, and a control device.

[0003] Currently, most manufacturers set up a glue coating mechanism on the processing line of nonwoven fabric composite layers. The glue coating mechanism applies glue to the surface of the nonwoven fabric by roller, and then other fabrics are bonded to the nonwoven fabric to form a nonwoven fabric composite layer. However, because the glue has a certain stickiness, and most glue coating mechanisms cannot distribute the glue evenly on the nonwoven fabric, most of the glue is distributed in clumps on the surface of the nonwoven fabric. This phenomenon can easily lead to poor bonding quality between the nonwoven fabric and other fabrics during the processing of the nonwoven fabric composite layer. Utility Model Content

[0004] The main purpose of this invention is to propose a nonwoven fabric processing roller coating device, which aims to solve the technical problem that existing coating mechanisms cannot evenly distribute glue on nonwoven fabrics.

[0005] To achieve the above objectives, the present invention proposes a nonwoven fabric processing roller coating device, comprising mounting plates, connecting plates between the mounting plates, a nonwoven fabric roll between the mounting plates, other fabric rolls between the mounting plates, a first limiting roller between the mounting plates, a second limiting roller between the mounting plates, a pressing roller between the mounting plates, a third limiting roller between the mounting plates, and an adhesive application assembly between the mounting plates capable of uniformly roller coating the nonwoven fabric.

[0006] The glue application assembly includes a glue storage tank, a glue storage box, a glue dispensing pipe, a solenoid valve, a servo motor, a rotating shaft, a glue application roller, a groove, and a limiting side plate. The glue storage tank is located between the mounting plates, and the glue storage box is located between the mounting plates and above the glue storage tank. The glue dispensing pipe is connected to the bottom of the glue storage box. The solenoid valve is located on the outer surface of the glue dispensing pipe. The servo motor is located on the front side of the front mounting plate. The rotating shaft is coaxially connected to the output shaft of the servo motor via a coupling, and its other end passes through and is rotatably connected to the front side of the rear mounting plate. The glue application roller is sleeved on the rotating shaft, and the groove is formed on the glue application roller. The limiting side plate is located on the left side of the glue storage tank and is in contact with the glue application roller.

[0007] Optionally, the left side of the glue storage tank is arc-shaped, and the left side of the glue storage tank is tangent to the surface of the glue coating roller.

[0008] Optionally, the top of the glue storage tank is provided with a feed inlet.

[0009] Optionally, the tops of the first limiting roller, the connecting plate, the second limiting roller, and the third limiting roller are horizontally distributed.

[0010] Optionally, there may be multiple second limiting rollers, with intervals between them.

[0011] Optionally, there may be multiple third limiting rollers, with intervals between them.

[0012] The technical solution of this utility model has the following beneficial effects: When it is necessary to uniformly roll-coat glue onto non-woven fabric, the solenoid valve is opened, and the glue inside the glue storage tank flows into the glue storage tank through the glue outlet pipe. Then, the servo motor is started, and the rotating shaft drives the coating roller to rotate. When passing through the inside of the glue storage tank, the glue inside is applied to the surface of the non-woven fabric through the groove, so that the coating roller completes the uniform rolling coating on the surface of the non-woven fabric. Then, the non-woven fabric coated with glue is bonded to the fabric in other fabric rolls, and then pressed by the pressing roller, thereby completing the non-woven fabric composite layer processing and improving the quality of the non-woven fabric composite layer.

[0026] Specifically, the left side of the glue storage tank 61 is arc-shaped, and the left side of the glue storage tank 61 is tangent to the surface of the glue application roller 67, which facilitates the scraping and cleaning of glue on the surface of the glue application roller 67.
