Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric adhesive application technology, specifically to a nonwoven fabric adhesive application device. Background Technology

[0002] Non-woven fabrics possess characteristics such as moisture resistance, breathability, lightweight, non-flammability, easy decomposition, rich colors, low price, and recyclability. They are produced through a continuous one-step process involving high-temperature melting, spinning, laying, and hot-pressing. During the production process, non-woven fabrics require adhesive application. A search revealed existing technology (Announcement No.: CN202321884273.8) for non-woven fabric adhesive application equipment. The document describes a process where "the adhesive dripping component drips adhesive onto the glue delivery roller, and the adhesive on the roller flows between the delivery roller and the application roller, forming an application line. When the application roller rotates..." The adhesive adheres to the applicator roller with a thickness equal to the gap width. The applicator roller then rotates downwards to apply the adhesive to the upper surface of the nonwoven fabric. This replaces the existing method of applying adhesive directly to the nonwoven fabric surface with a scraper. The nonwoven fabric bonding equipment proposed in this invention has a better adhesive application effect, spreads evenly, improves the bonding effect between the nonwoven fabric and the adhesive, and reduces the occurrence of bulging in the subsequent nonwoven fabric bonding process. However, the existing technology has problems with the glue delivery roller and applicator roller guiding the adhesive and easily absorbing nonwoven fabric or dust from the air during the application process, which affects the nonwoven fabric bonding effect. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a non-woven fabric adhesive application device is provided to solve the problems in existing technologies where the glue delivery roller and the application roller guide the glue flow, and the non-woven fabric or dust in the air is easily attracted during the application process, affecting the non-woven fabric adhesive application effect.

[0004] To achieve the above objectives, a non-woven fabric adhesive application device is provided, comprising: a non-woven fabric adhesive application machine, wherein a dust cover is fixedly installed on the upper surface of the non-woven fabric adhesive application machine.

[0005] The upper surface of the dust cover is connected to a dust collection frame via an adjusting stud. An electrostatic adsorption roller is axially connected to the inner side of the dust collection frame via a bearing. The electrostatic adsorption roller is electrically connected to an electrostatic generator. A dust collection port is opened on the upper inner wall of the dust collection frame.

A dust collection box is sealed and fastened to the lower end of the sealing cover. A dust collection box is inserted into the dust collection box. A first fan is installed on the left side of the dust collection box. A glue application roller is set on the right side of the dust collection frame. A glue guide roller is set on the upper left side of the glue application roller. Both the glue application roller and the glue guide roller are axially connected to a connecting fixing frame on their sides.

[0006] Furthermore, the nonwoven fabric applicator has a viewing window on its front surface and a conveyor belt installed inside the nonwoven fabric applicator; the conveyor belt is located at the lower end of the electrostatic adsorption roller and the adhesive coating roller.

[0007] Furthermore, the upper end of the dust collection frame is connected to the dust cover via a limiting rod, and an electrostatic generator is placed on the upper surface of the dust cover. The dust collection ports are located at the top of the electrostatic adsorption roller.

[0008] Furthermore, a dust collection box is supported on the left side of the dust cover, and filter screens are provided on the left and right sides of the dust collection box. The upper end of the fixing frame is connected to the dust cover via an electric push rod.

[0009] Furthermore, a glue spraying head is installed on the lower end face of the fixing frame, and a glue supply pipe is connected to the upper end of the glue spraying head; and the glue spraying head is located on the upper roller surface of the glue guide roller.

[0010] Furthermore, an exhaust hood is fixedly attached to the right end face of the dust cover, an exhaust port is opened on the inner inclined surface of the exhaust hood, and a second fan is installed on the upper surface of the exhaust hood.

[0011] Furthermore, a dust-blocking brush plate is fixed to the lower right end of the dust collection frame, and the upper end of the dust collection port is connected to a negative pressure pipe.

[0012] The beneficial effects of this utility model are as follows: the non-woven fabric adhesive application equipment of this utility model utilizes an electrostatic adsorption roller, an electrostatic generator, a dust collection frame, a negative pressure pipe, and a dust-blocking brush plate to form a pre-dust removal structure. The electrostatic adsorption roller rolls and adsorbs fibers and dust from the non-woven fabric adhesive application surface. The first fan then sucks the fibers and dust adsorbed on the surface of the electrostatic adsorption roller into the dust collection box for centralized collection, thus realizing a dustproof non-woven fabric adhesive application equipment. This facilitates the prevention of external dust and fiber impurities from entering the adhesive application equipment, while also facilitating the removal and cleaning of fibers and dust from the surface of the electrostatic adsorption roller. This prevents fibers and dust adhering to the surface of the non-woven fabric or adhesive roller from affecting the adhesive application effect, ensuring that the adhesive application equipment applies the adhesive evenly and smoothly to the surface of the non-woven fabric, thereby improving the production quality of non-woven fabric adhesive application.

[0019] Reference Figures 1 to 5 As shown, this utility model provides a non-woven fabric adhesive applicator, including: a non-woven fabric adhesive applicator 1, with a dust cover 11 fixedly installed on the upper surface of the non-woven fabric adhesive applicator 1.

[0020] The upper end of the dust cover 11 is connected to a dust collection frame 21 via an adjusting stud 24. An electrostatic adsorption roller 2 is axially connected to the inner side of the dust collection frame 21 via a bearing 28. An electrostatic generator 22 is electrically connected to the electrostatic adsorption roller 2. A dust collection port 26 is opened on the inner wall of the upper end of the dust collection frame 21. A sealing cover 32 is connected to the upper surface of the electrostatic adsorption roller 2 via a negative pressure pipe 23. A dust collection box 3 is sealed and fastened to the lower end of the sealing cover 32. A dust collection box 34 is inserted into the dust collection box 3. A first fan 31 is installed on the left side of the dust collection box 3. A glue application roller 4 is set on the right side of the dust collection frame 21. A guide roller 41 is set on the upper left side of the glue application roller 4. A connecting fixing bracket 45 is axially connected to the side ends of both the glue application roller 4 and the guide roller 41.

[0021] First, the non-woven fabric is laid flat on the surface of the conveyor belt 13 of the non-woven fabric applicator 1. The conveyor belt 13 moves the non-woven fabric to the lower roller surface of the electrostatic adsorption roller 2. The electrostatic adsorption roller 2 uses electrostatic adsorption technology to adsorb the fiber impurities on the surface of the non-woven fabric. When the adsorbed fiber impurities rotate to the top, they are sucked out by the dust suction port 26 and discharged into the dust collection box 34 in the dust collection box 3. This helps to prevent external dust and fiber impurities from entering the applicator, and at the same time, it facilitates the suction and cleaning of fibers and dust on the roller surface of the electrostatic adsorption roller 2, avoiding the non-woven fabric... Fibers and dust adhering to the surface of the cloth or coating roller 4 affect the coating effect. To ensure that the adhesive application equipment can apply the adhesive evenly to the surface of the non-woven fabric, the non-woven fabric after dust removal is conveyed to the coating roller 4 through the dust baffle 25. The rotating coating roller 4 evenly coats the non-woven fabric surface with adhesive. The coated non-woven fabric is then moved to the exhaust hood 5. The natural wind discharged through the exhaust port 52 of the exhaust hood 5 accelerates the drying of the non-woven fabric adhesive surface. After drying, it is conveyed out of the non-woven fabric adhesive application machine 1, thus completing the non-woven fabric adhesive application process.

[0022] In this embodiment, a viewing window 12 is provided on the front surface of the nonwoven fabric applicator 1, and a conveyor belt 13 is installed inside the nonwoven fabric applicator 1; the conveyor belt 13 is located at the lower end of the electrostatic adsorption roller 2 and the glue application roller 4. The upper end of the dust collection frame 21 is connected to the dust cover 11 through a limiting rod 27, and an electrostatic generator 22 is placed on the upper surface of the dust cover 11. The dust collection ports 26 are located at the upper end of the electrostatic adsorption roller 2.

[0023] In a preferred embodiment, the conveyor belt 13 facilitates the transport of the flat nonwoven fabric to the nonwoven fabric adhesive applicator 1, allowing the nonwoven fabric to be output after dust removal, adhesive application, and drying. The electrostatic generator 22 facilitates the generation of static electricity on the surface of the electrostatic adsorption roller 2, thereby attracting dust in the air around the electrostatic adsorption roller 2 and the fibers on the surface of the nonwoven fabric that are in rolling contact with it. This prevents the fibers and dust adhering to the surface of the nonwoven fabric or the adhesive roller from affecting the adhesive application effect, and facilitates the application of adhesive to the surface of the nonwoven fabric.

[0024] In this embodiment, a dust collection box 3 is supported on the left side of the dust cover 11, and filter screens 33 are provided on the left and right sides of the dust collection box 34. The upper end of the fixing frame 45 is connected to the dust cover 11 via an electric push rod 44. A glue spraying head 42 is installed on the lower end of the fixing frame 45, and a glue delivery pipe 43 is connected to the upper end of the glue spraying head 42; the glue spraying head 42 is located on the upper roller surface of the glue guide roller 41.

[0025] In a preferred embodiment, the first fan 31 at the side end of the dust collection box 3 generates negative pressure at the suction port 26 through the negative pressure pipe 23, thereby sucking out fibers and impurities from the surface of the electrostatic adsorption roller 2 and discharging them into the dust collection box 34 inside the dust collection box 3. Through the filter screens 33 on both sides of the dust collection box 34, air is discharged from the dust collection box 34 and the dust collection box 3, while dust and fiber impurities remain in the dust collection box 34, facilitating centralized cleaning of the sucked-out dust and fiber impurities. The glue delivery pipe 43 delivers the melted glue from the glue bucket to the glue delivery pipe 43 through an external screw pump, so that the glue delivery pipe 43 evenly sprays the glue onto the surface of the guide roller 41. The rotating guide roller 41 coats the glue onto the surface of the coating roller 4, so that the coating roller 4 rolls the glue on the surface of the non-woven fabric of the transmission belt 13.

[0026] In this embodiment, an exhaust hood 5 is fixedly attached to the right end face of the dust cover 11, an exhaust port 52 is opened on the inner inclined surface of the exhaust hood 5, and a second fan 51 is installed on the upper surface of the exhaust hood 5.

[0027] In a preferred embodiment, the second fan 51 blows air onto the surface of the non-woven fabric after coating through the exhaust port 52 at the inclined surface of the exhaust hood 5, thereby accelerating air circulation, speeding up the curing of the adhesive on the surface of the non-woven fabric, and reducing dust adhesion to the coated surface of the non-woven fabric.

[0028] In this embodiment, a dust-blocking brush plate 25 is fixed on the lower right frame of the dust collection frame 21, and the upper end of the dust collection port 26 is connected to the negative pressure pipe 23.

[0029] As a preferred embodiment, the dust baffle 25 effectively blocks dust entering from the left port of the dust cover 11, preventing dust and impurities from the external environment from entering the coating roller 4 and guide roller 41 inside the dust cover 11. The negative pressure generated at the suction port 26 removes fibers and dust from the surface of the electrostatic adsorption roller 2, facilitating the removal and cleaning of fibers and dust from the surface of the electrostatic adsorption roller 2 and ensuring the electrostatic dust collection effect of the electrostatic adsorption roller 2.

[0030] This utility model of nonwoven fabric adhesive application equipment effectively solves the problems in existing technologies where glue delivery rollers and coating rollers guide the glue flow and easily attract airborne nonwoven fabric or dust during the application process, affecting the nonwoven fabric adhesive application effect. It realizes a dustproof nonwoven fabric adhesive application equipment, which can easily prevent external dust and fiber impurities from entering the adhesive application equipment. At the same time, it can easily remove and clean the fibers and dust on the surface of the electrostatic adsorption roller, avoiding the fiber and dust adhering to the surface of the nonwoven fabric or coating roller from affecting the adhesive application effect. It ensures that the adhesive application equipment can apply the glue to the surface of the nonwoven fabric smoothly and evenly, improving the production quality of nonwoven fabric adhesive application. It is suitable for nonwoven fabric adhesive application equipment.
