Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, and in particular to an automatic glue spraying device for nonwoven fabric. Background Technology

[0002] Non-woven fabrics are a new type of environmentally friendly material widely used in industries such as medical, home furnishing, and personal care. Also known as nonwoven cloth, needle-punched cotton, or needle-punched nonwoven fabric, non-woven fabrics are made from polyester fiber (PET) through a needle-punching process, allowing for different thicknesses, textures, and hardnesses. To improve the performance of some non-woven fabric products, a spray-coating process is required. However, existing spray-coating equipment lacks automation, automatic feeding and transfer functions, and the spraying is not comprehensive, resulting in low-quality coating. The announcement number CN210031127U discloses a nonwoven fabric spraying device, comprising a frame, a spraying box mounted on the frame with an inlet and an outlet, a transfer roller mechanism disposed within the spraying box for conveying nonwoven fabric, multiple spraying heads for spraying dye onto the nonwoven fabric, and a feeding mechanism disposed on the spraying box for conveying dye to the spraying heads. The spraying box contains a horizontal second mounting plate, with the multiple spraying heads evenly arranged below the second mounting plate. A cylinder is provided on the spraying box to drive the second mounting plate to move up and down. The box body also has a lifting mechanism to drive the transfer roller mechanism to move up and down. This device lacks automation and the spraying is not comprehensive enough. Utility Model Content

[0028] In this embodiment, the first feeding conveyor belt 11 is mounted on the first frame 12, and the first frame 12 is equipped with a first drive motor 13. The first drive motor 13 is connected to a first reduction gearbox 131, which is used to drive the first feeding conveyor belt 11 to convey materials.

The multiple sliding rods 411 are connected to the pushing plate 43, and the pushing cylinder 42 is connected to the pushing plate 43. The pushing plate 43 is used to push the nonwoven fabric product from the first feeding conveyor belt 11 to the second feeding conveyor belt 21.

[0029] In this embodiment, the second feeding conveyor belt 21 is disposed on the second frame 22, and the second frame 22 is provided with a second drive motor, which is used to drive the second feeding conveyor belt 21 to convey; the second frame 22 is provided with a plurality of limit cylinders 23, and each limit cylinder 23 is connected to a limit frame 231.

[0030] In this embodiment, a lifting cylinder 25 is provided on the second frame 22, and the lifting cylinder 25 is connected downward to a lifting seat 251, which is connected downward to a nozzle 24.

[0031] In this embodiment, multiple adjusting screws 29 are rotatably connected to the second frame 22, and mounting brackets 28 are slidably connected to the left and right sides of the second frame 22 respectively.

[0036] In this embodiment, the specific glue spraying process is as follows: First, according to the specifications of the nonwoven fabric product, the positions of multiple nozzles 24 are adjusted. The piston rod of the lifting cylinder 25 extends and retracts to drive the lifting seat 251 and the corresponding nozzles 24 to move up and down until they reach the set position. Then, the rotating seat 271 is rotated to drive the nozzles 24 on the rotating seat 271 to swing horizontally until the nozzles 24 swing to the set angle. Finally, the adjusting handwheel 291 is rotated to drive the adjusting screw 29 to rotate, thereby moving the two mounting frames 28 closer to or further away from each other, and thus moving the nozzles 24 on the mounting frames 28 closer to or further away from the second feeding conveyor belt 21, completing the adjustment.

[0037] At this time, the first drive motor 13, the second drive motor, and the third feeding conveyor belt are started respectively. The first drive motor 13 drives the first reduction gearbox 131 to work, the first reduction gearbox 131 drives the first feeding conveyor belt 11 to convey, and the second drive motor drives the second feeding conveyor belt 21 to convey. Then, the non-woven products to be processed, such as non-woven bags, are placed one by one on the third feeding conveyor belt 31. The third feeding conveyor belt 31, together with the conveyor plate 33, conveys the non-woven products one by one to the feeding end of the first feeding conveyor belt 11. Then, the first feeding conveyor belt 11 works to convey the non-woven products one by one from the feeding end of the first feeding conveyor belt 11 to the discharging end. At this time, the pusher cylinder 42 is activated, and the piston rod of the pusher cylinder 42 extends to drive the pusher plate 43 forward, so as to transport the non-woven fabric product from the discharge end of the first feed conveyor belt 11 to the feed end of the second feed conveyor belt 21. Then, the pusher cylinder 42 is controlled to reset. The extension and retraction of the pusher cylinder 42 are controlled in this way to transport the non-woven fabric product one by one to the second feed conveyor belt 21. The non-woven fabric product is transported one by one on the second feed conveyor belt 21 until it is transported to the corresponding nozzle 24 directly below or the nozzle 24 located on one side of the second feed conveyor belt 21 is facing the non-woven fabric product. At this time, the piston rod of the limiting cylinder 23 downstream of the nozzle 24 extends to drive the limiting frame 231 forward, so as to restrict the non-woven fabric product below the nozzle 24. The nozzle 24 sprays adhesive onto the non-woven fabric product. In this way, by using the cooperation of the limit cylinder 23 and the nozzle 24, the non-woven fabric product can be sprayed with adhesive from all directions. After the processing is completed, it is output through the second feeding conveyor belt 21.
