Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric equipment technology, and in particular to an ultrasonic welding device for nonwoven fabric seams. Background Technology

[0002] Non-woven fabric, also known as nonwoven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is made of polyester fiber and is produced through a needle-punching process, allowing for different thicknesses, feels, and hardnesses. Non-woven fabrics are characterized by moisture resistance, breathability, flexibility, lightness, flame retardancy, non-toxicity, odorlessness, low price, and recyclability. The production of non-woven fabric products involves processes such as cutting, corona treatment, static elimination, spraying, gluing, and welding. For some multi-layered non-woven fabric products, the production requires bonding the multiple layers together, typically using thermoforming or ultrasonic welding. However, existing non-woven welding equipment lacks sufficient automation, easily resulting in poor weld quality and unstable adhesion between multiple layers or individual non-woven fabric products. Announcement No. CN119388769A discloses an ultrasonic welding device for pure cotton spunlace nonwoven bags, relating to the field of ultrasonic welding technology. The device includes a mounting frame, with a connecting frame on the outer surface of the mounting frame and an ultrasonic generator on the inner wall of the connecting frame. A winding assembly is arranged between the opposing inner walls of the mounting frame. To prevent the welded nonwoven bags from being incompletely welded, the ultrasonic welding device uses multiple suction cups to open the interior of the bag. This device can only perform ultrasonic welding of nonwoven products but lacks other functions such as loading and unloading, resulting in insufficient automation and low processing efficiency.

[0034] In this embodiment, the specific welding process is as follows: First, the non-woven fabric product to be welded is placed on the first conveyor belt 11, and then the first drive motor 121 is started. The first drive motor 121 drives the first conveyor belt 11 to transport the non-woven fabric products to be welded one by one. When the nonwoven fabric product moves directly under the first detection head 13, the first detection head 13 performs the first detection on the nonwoven fabric product, and then controls the first conveyor belt 11 to continue conveying until the nonwoven fabric product moves directly under the dispensing head 14. At this point, the first drive motor 121 is stopped, and the first servo motor 144 and the first lifting cylinder 145 are started respectively. The first servo motor 144 drives the first screw to rotate, thereby driving the first translation seat 143 and the dispensing head 14 to move back and forth along the conveying direction of the first conveyor belt 11. The first lifting cylinder 145 drives the dispensing head 14 to move up and down, so that the dispensing head 14 dispenses glue to the corresponding position of the nonwoven fabric product. After the glue dispensing is completed, the first drive motor 121 is controlled to continue conveying the first conveyor belt 11 until the glued nonwoven fabric product moves directly under the second detection head 15. Then the first drive motor 121 is stopped, and the second detection head 15 performs a second detection on the glue dispensing of the nonwoven fabric product. After the detection is completed, the first drive motor 121 is controlled to continue conveying the first conveyor belt 11 until the nonwoven fabric product moves directly under the ultrasonic welding head 16. At this time, the corresponding product is placed on the glued area of ​​the non-woven fabric product to combine the two non-woven fabric products. Then, the second servo motor 163 and the second lifting cylinder 164 are started respectively. The second servo motor 163 drives the second screw to rotate, so as to drive the first sliding seat 162 and the ultrasonic welding head 16 to move back and forth along the conveying direction of the first conveyor belt 11. The second lifting cylinder 164 drives the ultrasonic welding head 16 to move up and down, so that the ultrasonic welding head 16 performs welding processing on the corresponding position of the non-woven fabric product. After welding is completed, the first drive motor 121 is controlled to move the welded nonwoven fabric product to the discharge end of the first conveyor belt 11. The first transfer robot is started, in which the third servo motor 23 and the third lifting cylinder 24 are started respectively. The third servo motor 23 drives the third screw to rotate, so as to drive the second translation seat 221 and multiple first vacuum suction cups 25 to move back and forth. The third lifting cylinder 24 drives the multiple first vacuum suction cups 25 to move up and down, so as to transfer the nonwoven fabric product at the discharge end of the first conveyor belt 11 to the second conveyor belt 31. Then the second drive motor 33 is started, and the second drive motor 33 drives the second conveyor belt 31 to transport the welded nonwoven fabric products one by one until they are transported to the discharge end of the second conveyor belt 31. At this time, the second material transfer robot is activated, including the fourth servo motor 42, the fifth servo motor 44, and the fourth lifting cylinder 45.

The fifth servo motor 44 drives the fifth screw to rotate, thereby moving the third translation seat 431 and multiple second vacuum suction cups 46 left and right. The fourth lifting cylinder 45 drives multiple second vacuum suction cups 46 up and down to transfer the non-woven fabric product from the discharge end of the second conveyor belt 31 to the discharge table 51. Then, the discharge table 51 is pushed to move and output the non-woven fabric product, completing the inspection, gluing, welding, and output of the non-woven fabric product.
