effects and effects of the embodiments
According to the automatic drawing, cutting and counting wool top machine equipment related by the embodiment, because the automatic drawing, cutting and counting 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, wherein a starting point travel switch and a terminal 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 terminal point travel switch, and 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 wire winding mechanism and the cutting mechanism according to the switch signals received by the switch signal receiving unit, thereby directly processing wool tops and metal wires into cut wool tops, omitting the process of carrying out manual secondary processing on long wool tops and avoiding various problems in the manual secondary processing, the production efficiency of the wool tops is obviously improved, and the production cost is greatly saved.
In addition, because the control part is provided with the counting unit, 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 controls the mobile station to stop at the position of the terminal travel switch and controls the counting unit to add 1 to the number of the wool tops, the counting unit can calculate the number of the wool tops in real time when one wool top is produced, the counting process is simple, the counting result is accurate, and the wool top yield management during the mass production of the wool tops is facilitated.
furthermore, the wool top storage mechanism comprises a first storage unit and a second storage unit, the first storage unit is provided with a turning plate capable of being opened and closed, the second storage unit is arranged below the first storage unit, therefore, the first storage unit can store wool tops produced in real time, when the wool tops stored in the first storage unit reach a preset number, the turning plate is opened, the wool tops with the preset number directly enter the second storage unit, the wool tops are counted again after being cleared, the number of the wool tops is increased by 1, after the turning plate is closed, the first storage unit continues to store new wool tops, meanwhile, a user can select to directly take out the wool tops from the second storage unit, and also can select to take out the wool tops when the number of the wool tops of the second storage unit reaches a certain number, so that the user can conveniently manage the produced wool tops.
further, alarm mechanism has the alarm lamp, and when the wool top root reached predetermined wool top root, the alarm lamp was opened, closed after the certain time interval, therefore every wool top of production, a user will be reminded to the alarm lamp, and convenience of customers manages the wool top of production.
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 operation control unit can also control the counting unit to judge whether the wool top bundle number reaches the preset wool top bundle number, and when the wool top bundle number reaches the preset wool top bundle number, the equipment is shut down. Therefore, the machine can be stopped to maintain every batch of wool tops with preset number, and the service life of the machine is prolonged.
Further, the control part is also provided with an input display unit, and a user can input specific numerical values of the preset time and the preset wool top quantity 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.
