[0004] In the lace machine of this structure, the flower wheel is movably connected to the transmission shaft through a sprocket and a chain, and the input end of the transmission shaft is connected to the transmission motor through a sprocket and a chain. The transmission motor is installed at the bottom of the workbench, and the transmission motor occupies the external installation space. Moreover, the transmission mechanism composed of the sprocket, chain, and transmission shaft occupies the internal space of the machine head. The transmission motor is connected to the transmission shaft through a sprocket and a chain, and the transmission shaft is connected to the flower wheel through a sprocket and a chain. The transmission path is long and runs through the entire machine head, occupying a large space, affecting the arrangement of other components such as wires and air pipes, and the arrangement is inconvenient. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems existing in the prior art and propose an ultrasonic lace machine, which solves the technical problem of how to make the driving component for driving the lace wheel to rotate occupy a small installation space and be convenient for layout.

[0006] The objective of the present invention can be achieved through the following technical solutions: an ultrasonic lace machine, comprising a workbench, a machine head fixed above the workbench and having a cavity inside, and an ultrasonic transducer assembly fixed below the workbench, the workbench having a first through hole therethrough, the suture end at the top of the ultrasonic transducer assembly being embedded in the first through hole, characterized in that the lace machine also comprises a first driving member fixedly connected to the machine head and a sliding frame fixedly connected to the output end of the first driving member, the first driving member being able to drive the sliding frame to move up and down, a second driving member being fixedly connected to the top of the sliding frame, and the second driving member being located in the machine head, a transmission mechanism being provided in the sliding frame, a flower wheel being provided at the bottom of the sliding frame, the second driving member being able to drive the flower wheel to rotate through the transmission mechanism, and the suture end interacts with the flower wheel to achieve suturing.

[0007] During operation, the sewing cloth is placed on the sewing end, the first driving member drives the sliding frame to move downward, that is, drives the flower wheel to move downward and press on the sewing cloth, the ultrasonic transducer assembly works to make the sewing end heat up, the second driving member works, drives the flower wheel to rotate through the transmission mechanism, thereby driving the sewing cloth to move, and sewing is achieved under the interaction between the sewing end and the flower wheel. The second driving member of the lace machine is directly fixed on the sliding frame and arranged in the cavity of the machine head, the transmission mechanism is arranged in the sliding frame, the second driving member and the transmission mechanism move up and down with the sliding frame, the second driving member and the transmission mechanism are both arranged on the sliding frame and located at the head of the machine head, the transmission path is short, the installation space occupied is small, and the arrangement is convenient. In the lace machine, only the second driving member is located at the head of the machine head, therefore, there is still a lot of space in the machine head, only a wire hole needs to be opened on the back of the machine head, the wire tube can be inserted into the machine head from the bottom of the workbench and then pass through the wire hole to connect the first driving member and the second driving member, avoiding the problem of the lace machine being messy and the wire tube being easily hooked caused by the wire tube being arranged outside the machine head, and the arrangement is convenient.

[0008] In the above-mentioned ultrasonic lace machine, the bottom of the machine head has a through notch, and the notch is located directly below the second driving member, and the second driving member can move outside the machine head through the notch. The setting of the notch prevents the second driving member from hitting the machine head when moving up and down, and rationally utilizes the space so that the second driving member can be installed in the machine head; at the same time, the setting of the notch can make the machine head smaller, saving materials and reducing costs.

[0009] As another case, in the ultrasonic lace machine described above, the machine head has a downwardly protruding accommodation cavity, and along the vertical direction, the accommodation cavity is located directly below the second driving member, and the second driving member can move downward and be located in the accommodation cavity. The head of the machine head can protrude downward a little, and the interior of the protruding part is the accommodation cavity, so that the accommodation cavity has enough space, so that the second driving member will not collide with the machine head when moving up and down, so that the second driving member can be installed in the machine head.

[0010] In the above-mentioned ultrasonic lace machine, the sliding frame has a long installation cavity, and the transmission mechanism includes a synchronous belt, a first synchronous wheel and a second synchronous wheel. The first synchronous wheel is arranged at the top of the installation cavity and is connected to the second driving member, and the second synchronous wheel is arranged at the bottom of the installation cavity and is connected to the flower wheel. The first synchronous wheel and the second synchronous wheel are connected through a synchronous belt. The connection transmission of the synchronous belt, the first synchronous wheel and the second synchronous wheel has low noise compared with the connection transmission of the sprocket and the chain; the connection transmission of the synchronous belt, the first synchronous wheel and the second synchronous wheel does not require the addition of lubricating grease, so the synchronous belt, the first synchronous wheel and the second synchronous wheel can be arranged in a relatively sealed installation cavity, further reducing noise, and also preventing the synchronous belt, the first synchronous wheel and the second synchronous wheel from being disturbed by the outside world during operation, thereby reducing the failure rate. In actual production, the transmission mechanism can also be a gear set, and through the cooperation of multiple gears, the second driving member can drive the flower wheel to rotate.

[0011] In the above-mentioned ultrasonic lace machine, the bottom of the sliding frame is provided with a first bearing and a second bearing, the second synchronous wheel is fixedly connected with a rotating shaft, one end of the rotating shaft is inserted into the first bearing, the other end of the rotating shaft passes through the second bearing and extends outside the sliding frame, the end of the rotating shaft outside the sliding frame is fixedly connected with a mounting plate, and the flower wheel is detachably fixed to the side of the mounting plate by fasteners. The pattern on each flower wheel is fixed. In production, flower wheels with different patterns need to be used. The lace machine only needs to disassemble and assemble the flower wheel by fasteners, and the flower wheel is installed on the side of the mounting plate. The flower wheel is easy to replace, so that the lace machine has a wide processing range; at the same time, the mounting plate is set to abut against the flower wheel, and the mounting plate serves as a mounting carrier, so that the flower wheel is easy to install.

[0012] In the above-mentioned ultrasonic lace machine, the first bearing and the second bearing are both universal bearings, and the end of the rotating shaft passing through the first bearing is rotatably connected with an adjusting bolt, and an adjusting gasket is arranged between the adjusting bolt and the first bearing. The setting of the universal bearing allows the rotating shaft to deflect by a certain angle, that is, the flower wheel can deflect by a certain angle, and the position of the adjusting gasket is changed by loosening the adjusting bolt, and then the adjusting bolt is tightened to press on the adjusting gasket, so that the adjusting gasket squeezes a certain part of the first bearing, so that the inner ring of the first bearing is deflected, thereby causing the rotating shaft and the flower wheel to deflect to a certain extent, so that the flower wheel can better cooperate with the sewing end, thereby improving the sewing quality.

[0013] In the above-mentioned ultrasonic lace machine, a third driving member is fixedly connected to the bottom of the workbench, a driving wheel is provided on the output shaft of the third driving member, and the third driving member can drive the driving wheel to rotate, a fourth driving member is fixedly connected to the machine head, a bracket is fixedly connected to the output shaft of the fourth driving member, and the fourth driving member can drive the bracket to move up and down, a rotatable driven wheel is provided in the bracket, and a second through hole is provided in the workbench, and the driving wheel can cooperate with the driven wheel through the second through hole. The driving wheel and the driven wheel cooperate to pull the sewing cloth to move, so that the sewing cloth can move better and faster along the set path, thereby improving the sewing efficiency.

[0014] In the above-mentioned ultrasonic lace machine, the first through hole is circular, the second through hole is rectangular or cube-shaped, and the edges at both ends of the second through hole are flush with the two sides of the first through hole or the edges at both ends of the second through hole are expanded outward relative to the two sides of the first through hole. The sewing position of the sewing cloth is at the bonding point between the flower wheel and the sewing end. This arrangement of the second through hole ensures that the driving wheel and the driven wheel can better pull the sewing cloth to move, thereby improving the sewing efficiency.

[0015] In the above-mentioned ultrasonic lace machine, the bottom of the workbench has a pair of protruding lugs, the driving wheel is located between the pair of lugs, a driving shaft is fixedly connected to the driving wheel, and the two ends of the driving shaft are respectively rotatably connected to the corresponding lugs, and the output shaft of the third driving member is connected to the driving shaft through a gear combination or a synchronous pulley combination. The third driving member itself has a certain volume, and the output shaft of the third driving member is relatively far away from the second through hole. The arrangement of the driving shaft, gear combination or synchronous pulley combination allows the driving wheel to be closer to the second through hole, and the space is reasonably used, so that the driving wheel can be made smaller accordingly.

[0016] In the above-mentioned ultrasonic lace machine, a mounting plate is fixedly connected to the machine head, the first driving member is fixedly connected to the top of the mounting plate, the fourth driving member is fixedly connected to the bottom of the mounting plate, a guide rail is fixedly connected to the mounting plate, and the sliding frame can slide along the guide rail.

[0017] In the above-mentioned ultrasonic lace machine, the ultrasonic transducer assembly includes a fifth driving member, and the fifth driving member can drive the suturing end to rotate. The suturing end is rotatable, so that the lace machine can sew in a straight line or in a curve.

[0018] In the above-mentioned ultrasonic lace machine, the first driving member and the fourth driving member are driving cylinders or driving oil cylinders, and the second driving member, the third driving member and the fifth driving member are servo motors or rotary cylinders.

[0019] Compared with the prior art, the ultrasonic lace machine provided by the present invention has the following advantages:

[0020] 1. The second driving member of the ultrasonic lace machine is directly fixed on the sliding frame and arranged in the cavity of the machine head. The transmission mechanism is arranged in the sliding frame. The transmission path is short, the installation space occupied is small, and the layout is convenient. At the same time, the wire tube used to connect the driving member can be passed from the bottom of the workbench into the machine head and then passed out and connected to the corresponding driving member. The wire tube is easy to arrange and the space is reasonably used, avoiding the problem of the lace machine being messy and easy to hook caused by the wire tube being arranged outside the machine head.

[0021] 2. The driving wheel, flower wheel and sewing end of this ultrasonic lace machine are independently controlled by different driving parts. The movement of the driving wheel, flower wheel and sewing end is not affected by each other. By setting reasonable parameters, the processing speed of this lace machine can be improved.
