The feeding clamp includes a feeding clamp fixing seat and a feeding clamp clip; the feeding clamp cooperates with the feeding cylinder to form a feeding mechanism;

[0007] The clamping mechanism comprises a working panel, a clamping motor, a clamping driving gear, a clamping driven toothed disc and a clamping sheet, wherein the clamping motor is fixed behind the working panel, the clamping driving gear and the clamping driven toothed disc are both in a clamping groove, the clamping driving gear is fixed to the clamping motor and matches with the clamping driven toothed disc, the clamping driven toothed disc is provided with a toothed disc guide groove, the clamping sheet is provided with a clamping sheet fixing column and a clamping sheet guide column, the clamping sheet guide column matches with the toothed disc guide groove of the clamping driven toothed disc, the clamping sheet fixing column matches with the clamping sheet fixing hole on the working panel to form a complete clamping mechanism;

[0008] The wire winding mechanism comprises a wire winding turntable, a wire winding motor, a wire winding driving gear, a wire winding driven gear, a wire unwinder, a wire unwinding clamp and a wire unwinding guide column, as well as a threading cylinder and a counter.

[0009] Furthermore, the CNC system includes PLC, human-machine interface, feeding motor information processing module, feeding cylinder information processing module, clamping motor information processing module, threading cylinder information processing module, winding motor information processing module, winding coil number information collection module; the feeding motor information processing module is used to control the operation of the feeding motor; the feeding cylinder information processing module is used to control the movement of the feeding cylinder; the clamping motor information processing module is used to control the operation of the clamping motor; the threading cylinder information processing module is used to control the movement of the threading cylinder; the winding motor information processing module is used to control the operation of the winding motor; the winding coil number information collection module is used to receive the counter signal and transmit the signal to the CNC system.

[0010] Furthermore, the threading cylinder is fixed on the working panel, is located inside the winding turntable, and forms an angle of 15° to 20° with the working panel.

[0013] The present invention also discloses a control method for a fully automatic broom bundling machine, comprising the following steps:

[0014] (1) The feeding motor information processing module controls the operation of the feeding motor. After the feeding clamp is sent to the specified position, the feeding motor stops running;

[0015] (2) The feeding cylinder information processing module controls the feeding cylinder to move the feeding clamp to the broom seedling. The feeding clamp opens during the feeding process. When the broom seedling reaches the storage table, the feeding clamp just places the broom seedling in the clamp. The feeding clamp picks up the broom seedling and returns to the original position.

[0020] (7) The counter counts the number of times the magnetic point passes through, and controls the number of turns of the binding wire. When the specified number of turns is reached, the counter transmits a signal to the winding wire number information acquisition module, and the winding wire number information acquisition module transmits a signal to the numerical control system. The winding wire information acquisition and processing module controls the winding wire motor to stop running, and a broom binding work is completed;

[0021] After completing steps (1) to (7), that is, a broom bundling work, the clamping motor information processing module controls the clamping motor to operate, the clamping plate retracts, and the broom seedling is released. The feeding motor information processing module operates the feeding motor to send the broom seedling forward to a specified distance. The clamping motor information processing module controls the clamping motor to operate, the clamping plate shrinks, and after the broom seedling is clamped, the wire winding mechanism operates to complete the wire winding work, and the operations are carried out in sequence to complete the entire broom bundling work.

[0022] The advantages of the present invention are: 1. The degree of automation is high, and the automatic bundling of brooms can be realized; 2. The bundling speed is fast, and the work efficiency is improved; 3. The labor intensity of manual labor is reduced, and labor is saved. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Working process of the wire winding mechanism: after the clamping mechanism clamps the broom seedling, the threading cylinder 8 is activated to thread the binding wire to the clamping point of the broom seedling, the threading cylinder 8 retreats, and the wire winding motor 17 runs, driving the wire winding turntable 3 to rotate through the wire winding active gear 7 and the wire winding driven gear 2, and the wire unwinder 6 slowly releases the binding wire through the wire unwinding clamp 5 and the wire unwinding guide column 4. The tightness of the binding wire wrapped around the broom can be adjusted by adjusting the wire unwinding clamp 5.
