polymer welder.The production method of ultrasonic lace machine

　　According to the commonly seen ultrasonic lace wave machine, it mainly uses the flower wheel with concave and convex patterns on the top and the circular horn seat below to press, bond, cut, and emboss the fiber fabric using ultrasonic waves. Due to the common use of products to ensure average contact wear between the flower wheel and the horn, the circular horn seat is rotated in a self rotating manner. However, this type of product often rotates in a self rotating manner due to the direct rotation of the flower wheel and the circular horn seat, Due to the distortion of the processed fabric, operators often place the flower wheel on one side of the centerline of the circular horn disc to prevent distortion; If the flower wheel is placed beyond the centerline of the speaker disc, the concave and convex patterns on the flower wheel, if coincidentally placed in the central position, will cause the speaker seat in contact with it at the center to produce a concave phenomenon (because although the speaker seat operates in a rotational manner, its center point is like a fixed point at the center of the circle, and it continues to be subjected to force), The ultrasonic machining machine uses the high-speed oscillation of the horn disc and a flower wheel with concave and convex grooves to achieve cutting or embossing of the processed object that passes through it. Therefore, the production of the horn disc is the high-tech of the operator, especially to achieve the purpose of wear resistance. How to process a circular horn disc with uniform surface hardness has always been a concern for the operator. The cover is treated as a hardness treatment. When the circular horn disc is heated and heated, the outer periphery is directly heated and then transmitted to the center of the circle. At this time, the temperature on the outer periphery of the circle is the highest, and when it is cooled rapidly, the temperature on the outer periphery of the circle is the lowest and the temperature on the center is the highest. Therefore, the larger the circular horn disc, the more difficult the hardness treatment is, and the higher the failure rate (relative cost is higher). Therefore, it is often necessary to remove the horn seat and grind it, As a result, it causes great inconvenience in use; Furthermore, the speaker base is made of special materials (i.e. high hardness), and its grinding cost is quite high. It is also time-consuming to disassemble and assemble the speaker base, which delays the progress of work. These shortcomings have been troubling both businesses and consumers for a long time. Therefore, can a mechanical structure device be provided to improve the above shortcomings, so that the wear of the speaker disc is more uniform without central protrusion, and the fabric will not undergo twisting and squeezing, This is the motivation behind this utility model.

　　Due to the lack of practical equipment, this utility model has accumulated many years of design experience in the ultrasonic industry. Through continuous research and innovation, as well as long-term trial and improvement, this utility model has finally been born. Its main feature is that there is a horn disc and a stainless steel plate on the machine board below the flower wheel that can achieve synchronous forward and backward displacement. The first two are respectively connected by connecting rods and fixed clamps on movable brackets, On the movable bracket, there is a sliding seat that acts on the track on the bracket. By using the long groove in the center of the movable bracket and the bearing of the eccentric wheel shaft in front of the motor on the bracket, the front and rear displacement can be achieved.

　　According to the present utility model, an ultrasonic lace machine is provided, which is equipped with a grip handle in front of the frame above the machine board, and an upper pressing wheel that can move up and down with the grip handle below the grip handle. Below the upper pressing wheel is a stainless steel plate with a partition strip, and below it is a lower pressing wheel with a groove that acts on the upper pressing wheel, causing the common fabric to be pulled and displaced; A flower wheel with raised patterns is installed behind the upper pressure wheel and rotates synchronously with the lower pressure wheel. Its feature is that there is a stainless steel plate with a through-hole on the frame below the flower wheel, and a horn that can be used for front and rear displacement is also installed in the center of the through-hole. The horn and stainless steel plate are respectively fixed to the movable bracket by a fixed clamp seat and a connecting rod of the planting rod. A sliding seat that can be positioned and displaced with the track of the bracket is also provided on the movable bracket, with a long groove in the center, On the other bracket, there is a motor with a reducer in front, and in front of the reducer, an eccentric wheel shaft is fixed by a bearing. On one side of the eccentric wheel shaft, there is another bearing fixed by bolts in the long groove behind the center of the movable bracket to provide synchronous forward and backward displacement with the horn seat acting on the flower wheel and the stainless steel plate with a through hole in the center.
