Description

Technical Field

[0001] This utility model relates to the technical field of disposable hygiene product production equipment, specifically to an ultrasonic flip welding device with a flipping and limiting function. Background Technology

[0002] Currently, in domestic disposable hygiene product equipment, especially in pull-up trouser machinery, waistband welding is an important standard for product quality and one of the factors affecting machine start-up speed. Currently, ultrasonic flip welding devices are commonly used for ultrasonic welding of waistbands, such as the pull-up trouser ultrasonic flip welding device with authorization announcement number CN112873865B. However, in actual production, it was found that when the swing arm flips downwards and drives the patterned pressure plate down to the ultrasonic welding head for ultrasonic welding, because the swing arm is hinged at one end and suspended at the other, meaning only one end of the swing arm is supported while the other end is suspended and unsupported, resonance easily occurs between the swing arm and the ultrasonic welding head during ultrasonic welding. This affects the ultrasonic welding quality and welding precision of the material to be welded by the ultrasonic welding head and the patterned pressure plate. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an ultrasonic flip welding device that can limit the downward flipping of the swing arm and provide stable support for its suspended end. During the ultrasonic welding process, the swing arm is less likely to resonate with the ultrasonic welding head, which is conducive to better ensuring the quality and accuracy of ultrasonic welding.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an ultrasonic flip welding device with flipping and limiting function, comprising a swing arm, a flipping drive mechanism, a patterned pressure plate, an ultrasonic welding head, an annular seat, and an annular plate. The annular plate is disposed on one side of the annular seat, the ultrasonic welding head is mounted on the annular seat, the patterned pressure plate is mounted on the swing arm, one end of the swing arm is hinged to the annular plate, the flipping drive mechanism is used to drive the swing arm to flip and press down towards the ultrasonic welding head side, and a flipping limiting support component is provided on the outer circumferential surface of the annular seat on the side away from the annular plate. The flipping limiting support component can provide limiting support for the suspended end of the swing arm.

[0005] Furthermore, the flip-limit support assembly includes a support base and a limit rod. The limit rod is longitudinally adjustable and is mounted on the support base and connected by a connecting mechanism. The support base is locked and fixed to the annular seat by a locking mechanism.

[0006] Furthermore, the connecting mechanism includes an upper connecting nut and a lower connecting nut, the limiting rod is a screw, the support base is provided with a longitudinal through hole, the limiting rod passes through the longitudinal through hole and is threadedly connected to both the upper connecting nut and the lower connecting nut, the upper connecting nut and the lower connecting nut are respectively provided on the upper and lower sides of the longitudinal through hole.

[0007] Furthermore, the support base has a cavity that communicates with the longitudinal through hole and extends through its front and rear surfaces.

[0008] Furthermore, the flip-limit support assembly also includes a compression spring, which is sleeved on the limit rod and located between the upper connecting nut and the support base.

[0009] Furthermore, the upper middle part of the support base protrudes upward and forms a bump, with a longitudinal through hole penetrating the bump.

[0010] Furthermore, the locking mechanism includes multiple locking bolts, multiple locking holes at the bottom of the support base, and multiple threaded holes on the outer circumferential surface of the annular seat. The number of multiple locking bolts, multiple locking holes, and multiple threaded holes are consistent and correspond one-to-one. The locking bolts pass through the locking holes and are threadedly connected to the threaded holes.

[0011] Furthermore, locking blocks are fixedly provided on both the left and right sides of the bottom of the support base, and locking holes are provided on the locking blocks and extend through their upper and lower ends.

[0012] Furthermore, a flip-limiting support assembly is also provided on the outer circumferential surface of the annular seat on the side near the annular plate.

[0013] As described above, the ultrasonic flip welding device with flipping and limiting function provided by this utility model has the following beneficial effects: By setting the flipping and limiting support component, when the swing arm flips downward and drives the patterned pressure plate to press down to the ultrasonic welding head and cooperate with the ultrasonic welding head for ultrasonic welding, the flipping and limiting support component can flip the swing arm downward to play a flipping and limiting role and provide stable support for its suspended end. That is, at this time, both ends of the swing arm are provided with corresponding stable support, thereby making the flipping and pressing state of the swing arm more stable. In addition, it can also effectively avoid excessive flipping and pressing of the swing arm. As a result, during the ultrasonic welding process, the swing arm is less likely to resonate with the ultrasonic welding head, which is conducive to better ensuring the ultrasonic welding quality and welding accuracy of the ultrasonic welding head and the patterned pressure plate on the material to be welded.

Detailed Implementation

[0018] The present invention will be further described below through specific embodiments.

[0019] like Figs. 1 to 3 As shown, the ultrasonic flipping welding device with flipping and limiting function of this utility model includes a swing arm 1, a flipping drive mechanism 2, a patterned pressure plate 3, an ultrasonic welding head 4, an annular seat 5, and an annular plate 6. The annular plate 6 is disposed on one side of the annular seat 5, the ultrasonic welding head 4 is mounted on the annular seat 5, the patterned pressure plate 3 is mounted on the swing arm 1, and one end of the swing arm 1 is hinged to the annular plate 6. The flipping drive mechanism 2 is used to drive the swing arm 1 to flip and press down towards the ultrasonic welding head 4. A flipping limiting support component 7 is provided on the outer circumference of the annular seat 5 on the side away from the annular plate 6. The flipping limiting support component 7 can provide limiting support for the suspended end of the swing arm 1.

[0020] With the setting of the flip-limit support component 7, when the swing arm 1 flips downward and drives the patterned pressure plate 3 to press down to the ultrasonic welding head 4 and cooperate with the ultrasonic welding head 4 for ultrasonic welding, the flip-limit support component 7 can flip the swing arm 1 downward to play a flip-limit role and provide stable support for its suspended end. That is, at this time, both ends of the swing arm 1 are provided with corresponding stable support, so that the flip-down pressing state of the swing arm 1 is more stable. In addition, it can also effectively prevent the swing arm 1 from flipping down too much. As a result, during the ultrasonic welding process, the swing arm 1 is less likely to resonate with the ultrasonic welding head 4, which is conducive to better ensuring the ultrasonic welding quality and welding accuracy of the ultrasonic welding head 4 and the patterned pressure plate 3 to be welded.

[0021] Furthermore, the swing arm 1, the flipping drive mechanism 2, the patterned pressure plate 3, and the ultrasonic welding head 4 are all existing structures, so they will not be described in detail here.

[0022] The flipping limiting support assembly 7 includes a support base 71 and a limiting rod 72. The limiting rod 72 is longitudinally adjustable and is mounted on the support base 71 and connected by a connecting mechanism. The support base 71 is locked and fixed to the annular seat 5 by a locking mechanism.

[0023] Accordingly, the connecting mechanism includes an upper connecting nut 731 and a lower connecting nut 732. The limiting rod 72 is a screw. The support base 71 is provided with a longitudinal through hole 711. The limiting rod 72 passes through the longitudinal through hole 711 and is threadedly connected to both the upper connecting nut 731 and the lower connecting nut 732. The upper connecting nut 731 and the lower connecting nut 732 are respectively located on the upper and lower sides of the longitudinal through hole 711. This facilitates the adjustment of the longitudinal position of the limiting rod 72 on the support base 71 and makes it easy to lock and fix. In addition, the support base 71 is provided with a cavity 712 that communicates with the longitudinal through hole 711 and penetrates its front and rear surfaces. Correspondingly, the lower connecting nut 732 is located in the cavity 712, making the overall structure more reasonable and compact.

[0024] The flip-limit support assembly 7 also includes a compression spring 75, which is sleeved on the limiting rod 72 and located between the upper connecting nut 731 and the support seat 71. In this way, when the swing arm 1 flips downward and the suspended end of the swing arm 1 abuts against the limiting rod 72, the compression spring 75 can play a certain buffering role to avoid hard contact.

[0025] Furthermore, the upper middle part of the support base 71 protrudes upward and forms a protrusion 713, and the longitudinal through hole 711 penetrates the protrusion 713. This helps to increase the depth of the longitudinal through hole 711, thereby increasing the length of the limiting rod 72 in the longitudinal through hole 711, and further improving the installation stability of the limiting rod 72 in the support base 71.

[0026] Correspondingly, the locking mechanism includes multiple locking bolts 741, the bottom of the support base 71 is provided with multiple locking holes 714, and the outer circumferential surface of the annular seat 5 is provided with multiple threaded holes. The number of multiple locking bolts 741, multiple locking holes 714 and multiple threaded holes are consistent and correspond one-to-one. The locking bolts 741 pass through the locking holes 714 and are threadedly connected to the threaded holes. Locking blocks 715 are fixedly provided on both the left and right sides of the bottom of the support base 71. The locking holes 714 are provided on the locking blocks 715 and pass through their upper and lower ends, thereby facilitating the locking of the support base 71 to the outer circumferential surface of the annular seat 5.

[0027] In addition, the flipping limiting support component 7 is also provided on the outer peripheral surface of the annular seat 5 on the side close to the annular plate 6, so as to provide more stable support for the swing arm 1.

[0028] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
