The thread twisting quantity is accurate, the phenomena of falling from the shaft and breaking the threads can not happen, and the use rate of the sewing threads is increased.

Description

Semi-automatic wrapping machine

This utility model relates to a kind of wind of medical operation suture thread.

Medical operation suture thread generally is to deposit with the form of axis, before the clinical use, needs stitching thread is rewinded on a kind of bobbin core of rubber tubular from bobbin.Because the internal diameter of this rubber bobbin core is variant, sometimes can not with the supporting use of the rotating shaft of existing kinking machine.Like this must be in rotating shaft sticking cloth, the overstriking rotating shaft, cooperation just is tight, realizes normal kinking.Existing kinking machine is to make power set with motor, and the bobbin core directly is inserted into and carries out kinking on the motor output revolving shaft.Need to smooth out with the fingers stitching thread during kinking and swing back and forth, make kinking even with hands.Because the motor speed height, bobbin core length is short, and the swing of hands is wayward, therefore often causes kinking to take off axle, the one, and the delay time at stop, the 2nd, can not in time stop, can not hold suitable kinking halt.

The purpose of this utility model just provides a kind of semiautomatic plant of adjustable-speed, smoothes out with the fingers the unstable working state of operation to eliminate hands, realizes accurately stopping of kinking, thereby guarantees the kinking quality, increases work efficiency.

This utility model is achieved in that an end that motor is contained in base, and reel is fixed on by the motor output shaft.The other end of base is fixed with axis locating shaft, line bar and tension adjustment clamping plate.Be equipped with along coil on the top of line bar, and foot-operated speed-regulating switch keeps being electrically connected by lead and motor.Starting point of the present utility model is to utilize some parts and the principle of existing sewing machine to design this device, promptly utilize reach the standard grade peg or spindle in the shuttle of sewing machine to replace the bobbin core of rubber tubular, can utilize combining of peg or spindle kinking mechanism on motor, speed-regulating switch and the sewing machine thus, realize goal of the invention of the present utility model.

Below in conjunction with accompanying drawing this utility model is further described.

Fig. 1 is a structural representation of the present utility model.

As shown in the figure, base 13 is a rectangular metal plate, and motor 16 is fixed on an end of base 13, and the motor next door is reel fixedly.Reel is connected and composed by tension disc 1, kinking rotating shaft 2, speed governing button 3, spanner 4 and rubber tire 5, and rubber tire 5 is positioned at the front upper place of motor output shaft 6.Kinking mechanism on each parts of this reel and connected mode and the existing sewing machine is basic identical.Spanner 4 has constituted a clutch controller with tension disc 1, and realization rubber tire 5 contacts and disengaging with motor shaft 6.The other end at base 13 is fixed with 5 axis locating shafts 10, can twine the stitching thread of five kinds of different models fast on same device.Also fix long line bar 14 in the centre of 5 locating shafts 10, be equipped with along coil 8 on the top of line bar 14, can take into account the suitable line needs of each locating shaft like this.Tension adjustment clamping plate 11 are fixed near the locating shaft 10 the base, and it is relative with kinking rotating shaft 2, to rotating shaft 2 transmission certain tensile stitching thread to be arranged.The version of tension adjustment clamping plate also with sewing machine head on thread tension to regulate the clamping plate form basic identical.Foot-operated speed-regulating switch 12 is electrically connected with motor 16 by lead 15, and this speed-regulating switch is the commercial approved product.

For improving the security performance of this device, be fixed with safety guard 17 at the casing side roof part of motor 16, this backplate forward position has hidden 1/3rd motor output shaft, to prevent scratch.Broken string serrated knife 7 also is installed on backplate 17, blocking the stitching thread that twines conveniently, and use the shears appliances in addition, the raising work efficiency.Bottom, four corners at base 13 also is fixed with Rubber shock-absorbing pad 18, to reduce noise.

The concrete operations of this device are that wound portion is placed on the workbench, and foot-operated speed-regulating switch 12 is put in ground.Get axis type stitching thread 9 and insert on the axis locating shaft 10, will sew up the end of a thread and extract out, wear the suitable coil 8 on the mast 14, the eyelet from the tension adjustment clamping plate 11 penetrates again, lays out between two clamping plate, twines on peg or spindle.Peg or spindle is penetrated kinking rotating shaft 2, go up no good hands 4, tension disc 1 is pressed on the peg or spindle automatically, and rubber tire 5 compresses with motor output shaft 6 and contacts simultaneously.Energized steps speed-regulating switch 12, motor starting, and reel begins kinking, and rotating speed is by foot-operated pressure size adjustment.When stitching thread twines full peg or spindle, tension disc 1 is backed down automatically, and kinking rotating shaft 2 and rubber tire 5 break away from stalls with motor shaft 6.Unclamp speed-regulating switch, take off peg or spindle, on broken string serrated knife 7, cut off stitching thread, promptly twined an axis.The shuttle changing core repeats above-mentioned action in addition.

This device is safe in utilization, and is easy and simple to handle, laborsaving during the kinking joint, and work efficiency improves 2-4 doubly, and the kinking quality is good, and the kinking amount is accurate.
