[0002] In the preparation process of sanitary products, the waistline part needs to be pressed, because the waistline is formed by folding the two sides, and then needs to be pressed and cut to form the waistline part of each product. In the pressing process, ultrasonic pressure welding equipment is generally used to press and bond several layers of non-woven fabrics.

[0003] The bottom roller used in the ultrasonic welding device in the prior art needs to be replaced with different bottom rollers when producing products of different specifications. The replacement and installation of the bottom rollers are generally completed by multiple screws. Therefore, when disassembling and installing, the screws need to be removed one by one, which is relatively cumbersome. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the utility model is to provide an ultrasonic bottom roller, which is convenient for disassembly and installation of the bottom roller.

[0016] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1 , Figure 3 and Figure 5 The present embodiment provides an ultrasonic bottom roller, comprising a mounting seat 1 and a roller body 2. The roller body 2 is fixedly mounted on the mounting seat 1 by a clamp 3. The clamp 3 comprises two clamping blocks 31. A slide groove 32 is provided in the clamping block 31. A clamping plate 33 is slidably provided in the slide groove 32. The clamping plate 33 is fixedly connected to the mounting seat 1. T-shaped grooves 34 are provided on opposite sides of the two clamping blocks 31. A limiting plate 35 adapted to the T-shaped groove 34 is fixedly mounted on one side of the roller body 2 close to the mounting seat 1. A fixing member 36 is installed on the clamping block 31.

[0018] In the initial state, the clamping block 31 is in a sliding state relative to the clamping plate 33. In the process of installing the roller body 2 on the mounting seat 1, the two clamping blocks 31 are first moved to the farthest distance between them, and then the roller body 2 is placed on the clamping plate 33. Then the staff drives the two clamping blocks 31 to move along the clamping plate 33 toward the direction of the roller body 2. During the movement of the clamping block 31, the limiting plate 35 on the roller body 2 gradually enters the T-slot 34 until the limiting plate 35 abuts against the inner wall of the T-slot 34, thereby limiting the roller body 2 under the interaction force between the limiting plate 35 and the inner wall of the T-slot 34, so that the roller body 2 is fixed together with the mounting seat 1 to realize the installation operation. After the clamping block 31 is positioned, the fixing member 36 is used to keep the clamping block 31 and the clamping plate 33 relatively still to prevent the movement of the clamping block 31 from causing the roller body 2 to fall off.

[0019] When disassembling the roller body 2, firstly, the stationary relationship between the block 31 and the clamping plate 33 is released by the fixing member 36, so that the block 31 and the clamping plate are in a relative sliding state, and then the staff drives the block 31 away from the roller body 2, and the limiting plate 35 on the roller body 2 is gradually pulled out of the T-shaped groove 34, thereby releasing the limit of the roller body 2, and then realizing the disassembly of the roller body 2.

[0020] When the staff drives the block 31 to move, the two blocks 31 need to be moved until the distance between the two blocks 31 is greater than the length of the roller body 2 before the roller body 2 can be disassembled, that is, after the limit plate 35 is completely separated from the T-slot 34, because the roller body 2 itself is long, the displacement of the block 31 required to be moved is also long, resulting in a long time consumption for moving the block 31 over a long distance, and on the other hand, the ultrasonic welding device has a tight structure inside, and is prone to limit conflicts with other structures when moving a long distance.

[0021] In order to solve the above technical problems, the moving distance of the block 31 is reduced and the replacement rate is increased. The openings of the two T-shaped slots 34 gradually decrease from the opposite side to the opposite side. Figure 2 As shown, the front cross-section of the T-slot 34 is a trapezoid, and the limiting plate 35 in the roller body 2 is adapted to the shape of the T-slot 34, so that the side of the limiting plate 35 close to the inner wall of the T-slot 34 is an inclined surface, and then when the block 31 moves in the direction away from the roller body 2, the block 31 only moves a short distance, and the limiting plate 35 can be completely separated from the T-slot 34, so that it is convenient for the roller body 2 to break away from the restriction of the block 31, thereby reducing the moving distance of the block 31, facilitating operation, reducing the replacement time, and also reducing the situation where the block 31 moves too much and causes a limit conflict with other components.

[0022] The fixing member 36 includes two bolts 37 arranged opposite to each other, through holes 38 for the bolts 37 to pass through are provided on the opposite sides of the two clamping blocks 31, and threaded holes 39 for threadedly matching with the bolts 37 are provided on both sides of the clamping plate 33. When it is necessary to keep the clamping block 31 and the clamping plate 33 relatively still, the staff drives the bolt 37 to rotate by a wrench, and the bolt 37 screws into the threaded hole 39. The clamping block 31 is limited by the bolt 37, so that the limiting plate 35 on the roller body 2 is closely attached to the inner wall of the T-shaped groove 34, so that the clamping block 31 cannot move, thereby strengthening the limiting of the clamping block 31 on the roller body 2 on the one hand, and keeping the clamping block 31 still relative to the clamping plate 33 on the other hand, preventing the clamping block 31 from moving and causing the roller body 2 to fall off.

[0023] A plurality of pressing teeth 4 are fixedly mounted on one side of the roller body 2 away from the mounting seat 1. The pressing teeth 4 press the non-woven fabric, thereby reinforcing the connection between the non-woven fabrics.

[0024] Changing the ultrasonic tooth shape will affect the connection force between non-woven fabrics and the softness of the material at the bonding point.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
