Embodiment

[0022] Such as Figures 1 to 4 As shown, a sheet fusion device 100 has: a frame body 3, an anvil roller 1, an ultrasonic welding head 2 paired with the anvil roller 1, and a moving plate 4 for fixing the ultrasonic welding head, which is used for inducing the ultrasonic welding head to be received by the sheet. The sensing part that exerts the reaction force on the object, the control system that receives the feedback signal of the sensing part and compares the reaction force value with the set value, and the clearance fine-tuning link mechanism. A guide rail is provided on the frame body 1, the ultrasonic welding head 2 is fixed on the flange 11, and the flange 11 can move vertically along the guide rail.

[0023] The sheet is transported to the gap between the ultrasonic welding head and the anvil roller to weld each other, and the moving plate can move relative to the anvil roller through the fine-tuning link mechanism of the gap, so that the ultrasonic welding head can mov...

Abstract

The invention discloses a sheet-shaped object welding device, which is provided with an ultrasonic welding head, an anvil roller and a gap fine-adjustment connecting rod mechanism, wherein sheet-shaped objects are conveyed to a gap between the ultrasonic welding head and the anvil roller so as to be welded with each other; the ultrasonic welding head is fixed on a moving plate; and the moving plate can move relative to the anvil roller through the gap fine-adjustment connecting rod mechanism so as to enable the ultrasonic welding head to move towards or away from the anvil roller. The sheet-shaped object welding device further comprises a sensing component used for sensing the magnitude of a counter-acting force exerted on the ultrasonic welding head by the sheet-shaped object, the sensingcomponent is provided with a pressure sensor, an upper connecting element and a lower connecting element. According to the invention, the pressure sensor is arranged between the upper connecting element and the lower connecting element, the upper connecting element is connected with the gap fine-adjustment connecting rod mechanism, the lower connecting element is connected with the moving plate,the gap fine-adjustment connecting rod mechanism and the moving plate are connected together through the pressure sensor, and the force borne by the moving plate is further detected. The sheet-shapedobject welding device has the advantages of simple structure, convenient installation and high reliability.

Description

technical field [0001] The present invention relates to the field of manufacturing disposable hygiene articles, in particular to a device for ultrasonically processing a sheet, which is one of single-layer and multi-layer finished or semi-finished products of sanitary articles or similar consumables . Background technique [0002] Conventionally, as a disposable sanitary product, for example, a disposable sanitary product having a front abdomen, a back portion and a crotch portion, wherein the front portion and the rear portion are ultrasonically welded via a pair of side seals (or welded portions) is known. When forming the side seal portion, continuously supply the thermoplastic sheet for constituting the front abdomen and the back portion to an anvil roller that can rotate around a predetermined axis, and cooperate with the anvil and be arranged on the The method between the ultrasonic horns with the outer peripheral surfaces of the anvil roll facing each other. The the...
