Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1 and 2, the filament unwinding mechanism 100 is a component of a cylindrical workpiece outer filament winding machine, and is responsible for releasing the filament 500 wound outside the cylindrical workpiece with a certain tension and making the filament 500 at a certain interval (same or changeable all the time) on the outer surface of the cylindrical workpiece
As shown in fig. 1 to 3, the cylindrical workpiece outer wire winding machine comprises a control system, a wire unwinding mechanism 100 and a cylindrical workpiece rotating mechanism 200 arranged at one side; the wire unwinding mechanism 100 is responsible for unwinding wires while moving and maintaining a certain tension, and the cylindrical workpiece rotating mechanism 200 is responsible for driving the cylindrical workpieces wound with wires to rotate; the two mechanisms cooperate to allow the wire 500 to be tightly and uniformly wound around the outer surface of the cylindrical workpiece.
The wire unwinding mechanism 100 comprises a trolley 130 and a wire unwinding part arranged on the trolley 130.
The trolley 130 is provided with a trolley driving mechanism, and the trolley driving mechanism is connected with a control system; a track 102 is arranged below the trolley 130, a rack 102a is arranged on the track 102, and a parking proximity switch and a parking travel switch are respectively arranged at two ends of the track 102; the trolley 130 is matched with the track 102 through wheels; the trolley driving mechanism comprises a trolley driving motor 118, and the trolley driving motor 118 is connected with the control system; a trolley driving gear 120 matched with the rack 102a is arranged on an output shaft of the trolley driving motor 118; the trolley drive motor 118 is also provided with a trolley drive motor speed sensor 112 connected to the control system.
The trolley 130 is used to move the filament feeding portion on the rail 102, but the rail 102 may be omitted. The speed at which the carriage 130 moves and the speed at which the cylindrical workpiece is rotated by the cylindrical workpiece rotating mechanism 200 together determine the pitch of the wire windings. The car drive motor speed sensor 112 will send the car drive motor speed to the control system to calculate the car 130 moving speed, and then calculate the car 130 moving distance and determine whether to accelerate, decelerate or stop.
The wire releasing part comprises a wire releasing frame 114, and the wire releasing frame 114 is fixedly arranged on the trolley 130; an adjusting screw 600 is arranged at the upper end of the wire releasing frame 114, the lower end of the adjusting screw 600 is connected with an adjustable wire passing arm seat 112, and the adjustable wire passing arm seat 112 is in up-and-down sliding fit with the wire releasing frame 114; the adjustable wire passing arm seat 112 is hinged with the adjustable wire passing arm 106 through the large shaft 108, and the adjustable wire passing arm 106 can move left and right on the adjustable wire passing arm seat 112; two ends and the middle end of the adjustable wire passing arm 106 are respectively provided with a wire releasing wheel 128, and three wire releasing wheels 128 are arranged.
Since the adjustable wire passing arm 106 moves up and down, the distance between the wire unwinding mechanism 100 and the cylindrical workpiece rotating mechanism 200 can also move. Therefore, the wire winding machine can be used for winding the outer surfaces of columnar workpieces such as reinforcing steel bar frameworks or rubber tubes with different diameters including larger diameters. The resistance to payout, that is, the tension of the wire wrap, is determined primarily by the size and angle of the diameters of the three payout rollers 128. The higher the position of the middle payout roller 128 relative to the other payout rollers 128, the more the angle of the formed yarn passing path is, the greater the resistance/tension, and the smaller the diameter of the payout roller 128, the greater the resistance/tension. And vice versa.
A tension adjusting spring 110 for buffering and adjusting the tension of the wire 500 is arranged between the adjustable wire passing arm 106 and the adjustable wire passing arm seat 112.
When the wire winding is started, because the wire disc 104 does not rotate, the resistance force is large due to the inertia, so that the adjustable wire passing arm 106 and the wire 500 can bear a very large tensile force instantly, and the tension adjusting spring 110 can buffer when the right end of the adjustable wire passing arm 106, which is the right end shown in fig. 1, sinks, so as to reduce the tensile force; meanwhile, the left end of the adjustable wire passing arm 106 can be tilted, so that the wire passing arm can be selected by pulling the wire disc 104 better and faster, and the wire passing arm enters a stable working state as soon as possible.
The wire releasing mechanism 100 further comprises a wire disc 104, the wire disc 104 is arranged on a trolley 130 through a wire disc jacking device 126, and the wire disc 104 is further connected with a wire loading motor 124 through a reduction gear box.
The wire 500 may also be loaded onto the wire reel 104 by the wire loading motor 124 if the wire reel 104 is not replaced. The wire disc 104 follows the trolley 130 and can be replaced quickly, so that the problem that the production efficiency is influenced because the wire is inconvenient to feed by the automatic wire winding machine of the applicant is solved. If the trolley 130 is not provided with the wire reel 104, the wire can be led from the wire unwinding mechanism 100 through a wire passing wheel group.
The wire unwinding frame 114 is provided with a wire returning prevention device 116, the wire returning prevention device 116 comprises a shock absorber 116b, one end of the shock absorber 116b is fixedly connected with the wire unwinding frame 114, the other end of the shock absorber 116b is provided with a pressing plate 116a, and the pressing plate 116a abuts against the wire reel 104.
If the anti-back-threading device 116 is not provided, after the winding is finished and the filament 500 is cut, the filament 500 will retract due to gravity, self rigidity and the like, so that several loops of the filament on the filament disc 104 are loosened, and the filament 500 is easy to exit from the filament-releasing part. Therefore, the next time the yarn is used, the yarn 500 is rearranged and then passes through the yarn releasing part, the working efficiency is influenced, and unnecessary workload is increased. The pressing plate 116a of the wire returning prevention device 116 can always give a certain pressure to the wire 500 on the wire reel 104 under the action of the shock absorber 116b, and the wire 500 is prevented from loosening and exiting the wire unwinding part.

And a transmission shaft rotating speed sensor 214 connected with the control system is arranged on the driven box 202, the driving box 212 or the transmission shaft 208. The transmission shaft rotation speed sensor 214 sends the rotation speed of the transmission shaft to the control system to calculate the rotation speed of the cylindrical workpiece, and then determines whether to accelerate, decelerate or stop.
The driven box 202 is provided with a jacking cylinder 202c for driving the jacking driven device 204 to move along the axial direction of the columnar workpiece in two directions; the driven box 202 is further provided with a tightening hand wheel 202a for driving the tightening driven device 204 to move in two directions along the axial direction of the columnar workpiece.

Thus, the wire winding machine can adapt to cylindrical workpieces with different lengths.
