DETAILED DESCRIPTION

[0018] In order to make those skilled in the art better understand the technical solution of the utility model, the following Figure 1-5 The utility model is further analyzed.

[0019] like Figure 1-Figure 5As shown, an improved ultrasonic welding sealing mechanism is characterized in that it includes a frame 1, a rotatable welding bottom roller 2 is provided on the inner side of the bottom of the frame 1, the welding bottom roller 2 is set as an unequal-sided octagonal prism structure, the two most distant rectangular planes of the eight rectangular planes on the side thereof are working surfaces 201, and the rest are non-working surfaces, the welding bottom roller 2 is installed on the frame through a bearing seat 3, one end of which is transmission-connected to a rotating motor 4, one side of the bearing seat 3 is provided with a height-adjustable brush roller group 5, and the brush roller group 5 A wet rag 6 is provided on the side away from the welding bottom roller 2. The diapers before entering the ultrasonic welding sealing mechanism are wiped by the brush roller group 5 and the wet rag 6 to clean the residual glue on the diapers and avoid the welding bottom roller from sticking. Two groups of ultrasonic welding heads 7 are provided in a V shape above the welding bottom roller 2. Negative pressure air ducts 8 are respectively provided on one side of the two groups of ultrasonic welding heads 7 for timely removing dust generated during ultrasonic welding. A baffle 9 is provided between the ultrasonic welding head 7 and the welding bottom roller 2 to prevent oil and dust from affecting the product.

[0020] In this embodiment, preferably, the two groups of ultrasonic welding heads 7 are respectively installed on the frame 1 through a sliding seat 10, and the top end of the sliding seat 10 is transmission-connected with a lifting motor 11 and an electric cylinder 12 for driving the ultrasonic welding heads 7 to lift and lower.

[0021] In this embodiment, preferably, an opening is provided through the middle of the baffle 9 for the two groups of ultrasonic welding heads 7 to pass through.

[0022] In this embodiment, preferably, the brush roller group 5 is installed on the bearing seat 3 through a height adjustment block 13, and the brush roller group 5 includes two groups of brush rollers arranged one above and one below, and the diaper entering the ultrasonic welding sealing mechanism passes between the two groups of brush rollers.

[0023] In this embodiment, preferably, the wet rag 6 is arranged on the height adjustment block 13 through a pressure plate, and is arranged on the side of the brush roller group 5 away from the welding bottom roller 2. The diaper is first moistened and wiped by the wet rag 6 before entering the brush roller group 5, and then passes through the brush roller group 5 to wipe off the glue remaining on it.

[0024] When the utility model is used: according to the thickness specification of the diaper, the ultrasonic welding head 7 is driven by the lifting motor 11 and the electric cylinder 12 to slide and lift on the sliding seat 10, and the height position of the ultrasonic welding head 7 is adjusted, thereby adjusting the distance between the ultrasonic welding head 7 and the working surface 201 of the welding bottom roller 2 to adapt to the diaper with this thickness specification to pass through. After the diaper is pulled out from the unwinding reel, it enters the welding sealing mechanism from the bottom of the wet rag 6 and the brush roller group 5, is first wetted and wiped by the wet rag 6, and then passes through the brush roller group 5 to wipe off the glue remaining on it, and then enters between the welding bottom roller 2 and the ultrasonic welding head 7 from the top of the baffle 9, and passes through between the ultrasonic welding head 7 and the welding bottom roller 2 uninterruptedly driven by the receiving reel, and the welding bottom roller 2 is also in a rotating state. When one of the two working surfaces 201 of the welding bottom roller 2 rotates to the ultrasonic welding When the ultrasonic welding head 7 is below the welding bottom roller 2, the ultrasonic welding head 7 and the welding bottom roller 2 are pressed and matched to weld and seal the diaper; at the same time, the welding and sealing position of the diaper can be adjusted by adjusting the rotation speed of the welding bottom roller 2 to adapt to the welding and sealing of diapers of different length specifications; specifically, since the winding speed of the diaper is constant, the slower the rotation speed of the welding bottom roller 2, the longer the time required for the two working surfaces 201 to rotate to the bottom of the welding bottom roller 2, and the longer the distance the diaper passes from the top of the welding bottom roller 2, so the larger the spacing between the welding and sewing positions at both ends of the diaper, and the longer the diaper produced; when the rotation speed of the welding bottom roller 2 is faster, the shorter the time it takes for the two working surfaces 201 to rotate to the bottom of the welding bottom roller 2, and the shorter the distance the diaper passes from the top of the welding bottom roller 2, so the smaller the spacing between the welding and sewing positions at both ends of the diaper, and the shorter the diaper produced. When the ultrasonic welding head 7 is welding and sealing the diaper, the dust generated by the ultrasonic welding head 7 during high-frequency vibration welding is promptly removed by the negative pressure air duct 8, and the welded and sealed diaper is sent out from the side of the welding and sealing mechanism away from the brush roller group 5.
