Effects and effects of the embodiments
According to the automatic drawing, rolling and slitting wool top machine equipment related by the embodiment, because the automatic drawing, rolling and slitting wool top machine equipment comprises a rack, a winding mechanism, a wire feeding mechanism, a wire clamping mechanism, a wire drawing mechanism, a winding mechanism, a cutting mechanism and a control part, a starting point travel switch and an end point travel switch are arranged on the rack, the control part is provided with a switch signal receiving unit and an operation control unit, the switch signal unit can receive switch signals sent by the travel switch and the end point travel switch, the operation control unit can control the operation of the winding mechanism, the wire feeding mechanism, the wire clamping mechanism, the wire drawing mechanism, the winding mechanism and the cutting mechanism according to the switch signals received by the switch signal receiving unit, therefore, the wool tops can be directly processed into the cut wool tops by the wool tops and the metal wires, the process of carrying out manual secondary processing on the long wool tops is omitted, the production efficiency of the wool tops is obviously improved, and the production cost is greatly saved.
In addition, because the operation control unit controls the stay wire drive unit and the winding drive unit to start at the same time, and controls the winding mechanism to wind and control the wire feeding mechanism to feed the wire at the same time after a third preset time interval, the stay wire mechanism and the winding mechanism can firstly wind the wool and the metal wire for a period of time, and then the winding mechanism winds and simultaneously feeds the wire by the wire feeding mechanism, so that the head end of the produced wool tops cannot form a wool coil but is uniform and smooth.
In addition, the operation control unit controls the winding mechanism to stop winding, the yarn feeding mechanism to stop feeding and the winding mechanism to stop winding at the same time, and controls the yarn pulling mechanism to stop pulling yarn after a fourth preset time interval, so that the yarn pulling mechanism can pull wool tops for a period of time more than needed, the tail end of the produced wool top cannot form a wool coil but is uniform and smooth, the head end of the next wool top is not easy to form the wool coil, and the quality of the wool top is improved.
furthermore, because the guide piece is also provided with the speed reduction travel switch, when the mobile platform moves to the position of the speed reduction travel switch along the direction close to the starting travel switch, the mobile platform can trigger the speed reduction travel switch to enable the speed reduction travel switch to generate a speed reduction switch signal, and after the switch signal receiving unit receives the speed reduction switch signal, the operation control unit controls the mobile platform to stop at the position of the starting travel switch after speed reduction, therefore, the mobile platform can move (return) from the end travel switch to the starting travel switch at a higher speed and stop at the position of the starting travel switch after speed reduction. Therefore, the return time of the mobile station is shortened, the production time of each wool top is shortened, the production efficiency is improved, and the phenomenon that the mobile station is rapidly braked to cause a large burden on a stay wire motor when directly moving to a starting point travel switch at a higher speed is avoided.
Furthermore, the control part is also provided with an input display unit, and a user can input a specific numerical value of the preset time through the input display unit so as to adjust the operation of the wool top machine equipment.
Further, since the wire drive unit is a servo motor, it is possible to perform speed control and position control of the mobile station more favorably.
Further, the guide and the moving stage are coupled by the lead screw nut, and therefore, the movement of the moving stage on the guide can be precisely controlled.
The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention.

Once the switch signal receiving unit receives a terminal switch signal formed by triggering the terminal travel switch in the process that the mobile station moves away from the starting travel switch, the operation control unit simultaneously controls the winding mechanism to stop winding, the wire feeding mechanism to stop feeding and the wire winding driving unit to close so that the rotary clamp stops winding, and after a fourth preset time interval, controlling the stay wire driving unit to stop so as to stop the mobile station at the position of the end-point travel switch, further controlling the cutting mechanism to cut off the wool tops, then controlling the wire clamping driving unit to close so that the rotating clamp loosens the wool tops, further controlling the wire drawing driving unit to start, so that the moving stage moves in a direction close to the start point stroke switch and stops at the start point stroke switch position.
2. the automatic lap slitting sliver machine equipment of claim 1, wherein:
wherein the guide piece is also provided with a deceleration travel switch which is arranged between the starting travel switch and the final travel switch,
When the moving table moves in the direction close to the starting point travel switch so as to trigger the speed reduction travel switch to enable the speed reduction travel switch to generate a speed reduction switch signal,
Once the switch signal receiving unit receives the deceleration switch signal, the operation control unit controls the operation of the pull line driving unit so that the mobile station continues to move in a direction close to the starting point travel switch at a decelerated speed after being decelerated and stops at the position of the starting point travel switch.
3. The automatic lap slitting sliver machine equipment of claim 1, wherein:
The control part is also provided with an input display unit, and the input display unit is used for allowing a user to input a specific numerical value of a preset time.
4. The automatic lap slitting sliver machine equipment of claim 1, wherein:
Wherein, the operation control unit comprises a Programmable Logic Controller (PLC).
5. The automatic lap slitting sliver machine equipment of claim 1, wherein:
Wherein the winding mechanism is provided with a rotating frame and a winding driving unit which is used for driving the rotating frame to rotate so as to drive the wool to rotate and enable the wool to be wound on one metal wire,
The wire feeding mechanism is provided with a wire feeding wheel arranged between the rotating frame and the cutting mechanism and a wire feeding driving unit for driving the wire feeding wheel to rotate so as to convey the wool and the two metal wires to the position of the cutting mechanism,
The cutting mechanism is provided with a cutting frame, a cutting knife arranged on the cutting frame and a cutting driving unit for driving the cutting knife to cut.
6. The automatic lap slitting sliver machine equipment of claim 5, wherein:
Wherein the wire drawing driving unit, the wire winding driving unit and the wire feeding driving unit are all driving motors connected with motor drivers,
The wire clamping driving unit and the cutting driving unit are air valves connected with air valve drivers.
7. The automatic lap slitting sliver machine equipment of claim 1, wherein:
The pull wire driving unit is a servo motor connected with a servo driver.
8. The automatic lap slitting sliver machine equipment of claim 1, wherein:
Wherein the guide and the mobile station are connected by a feed screw nut.
