When the motor starts running, the output shaft drives the stud to rotate, and then the internal threaded tube, the connecting rod and the fixed frame are slid downward through the sliding guide of the guide column and the fixed frame. First, the U-shaped pressing plate contacts the upper end of the bill of service, then the telescopic rod contracts, and the spring contracts to adapt until the hole-punching knife at the bottom of the internal threaded tube punches a hole at the binding position of the bill of service. With the support of the bottom hole-punching seat, the waste enters the inside of the hole-punching seat. Then, the motor is reversed through the single-chip microcomputer to move the hole-punching knife upward and reset. Then, the hole is filled with the binding hose and controlled by the single-chip microcomputer. Motor three starts to run, and the output shaft drives the rotation of the turntable. The rotating column slides and rotates inside the strip frame plate to realize the sliding downward movement of the connecting rod on the left side of the bottom wall of the vertical plate of the base until the heating rod penetrates into the inside of the binding hose. Then the single-chip microcomputer controls the heating rod to hot-melt the inner wall of the binding hose and applies a certain downward pressure to fix the binding hole with the thermoplastic tube to bind the labor service bill. After that, the single-chip microcomputer controls motor three to continue to operate, and the heating rod moves up and resets, which can realize continuous and efficient binding hole and hot-melt expansion operations. The binding of labor service bills has a high degree of automation, which reduces the burden on binding personnel.

[0022] 2. Then, through the control of the single-chip microcomputer, motor 2 and the photoelectric sensor start to run, and the output shaft drives the rotation of the gear. The rotation of the gear drives the movement of the rack plate fixedly connected to the rear side of the upper end of the binding table. The binding table slides in the dovetail slide groove through the dovetail slider and moves with the assistance of the ball sliding support. Under normal circumstances, the light receiver emitted by the light emitter of the photoelectric sensor cannot be found. When the photoelectric sensor is located on the front side of the upper end of the binding table and the positioning plate is moved to the front side of the vertical plate of the base, when the positioning plate passes, it blocks the light and reflects part of the light back. The light receiver in the photoelectric sensor receives the light signal and outputs a switch signal. The photoelectric sensor presents the detection data to the single-chip microcomputer in time, and the single-chip microcomputer stops the operation of motor 2. At this time, the hole opening seat is located on the lower side of the heating rod. When switching between the binding hole and the hot melt expansion, it can quickly locate and displace, reducing the positioning time, improving the accuracy of the bills for hot melt expansion fixed labor services, and the personnel participation in the conversion process is relatively small.
