[technical field]

The utility model relates to machine for zipper.

[technical background]

Slide fastener claims zip again, be one can repeat drawing, draw back by two flexibilities can intermeshing connector.It is one of most important invention in the world over more than 100 year, and common slide fastener form has single head to close the tail formula, double end is closed tail formula, double end tail-splitting type etc.

The chain tooth has the branch of size, and profile of tooth is had nothing in common with each other, and the pull head moulding is full of variety, and both can shake hands, and can decorate again.Pull head also can insure, and can not slip off automatically after the slide fastener drawing: the operation principle of slide fastener is very simple, and promptly two zipper strips are by the effect of pull head, makes the drawing that it can be random or draws back.

Various two chain tooth bands that match, by the effect of pull head, drawing that can be random or draw back, when pull head moved forward, the chain tooth pin on two chain tooth bands was pushed because of the shape restriction of pull head inner chamber dwell angle, thereby mutual well-regulated engagement, this has just formed the closure state of slide fastener.When pull head is pulled to the summit of slide fastener, because of the width of last width after only closing up greater than pull head inner chamber narrowest place, and pull head has been play a part spacing, the unlikely what of pull head is come off from chain belt, when pull head pulls back, draw the effect at the angle of riving (dihedral angle) that the both sides cylinder of scapus forms that the Ya Feng of chain tooth is separated one by one with tooth paddy by what pull head inner chamber, two chain tooth bands are separated.When pull head is pulled to the bottom of chain,, make pull head be unlikely to come off from chain belt because of the width of going up down tooth plays a part spacingly greater than the width of pull head inner chamber oral area.

At present, the machine for zipper that slide fastener is carried out machine-shaping mainly contains two kinds of vertical electric cabinet and horizontal electric cabinets.The structure and the basic principle of these two kinds of machine for zipper are basic identical, and difference mainly is the form difference of electric cabinet.Its concrete structure as shown in Figure 1, but actuating motor 12 runnings behind the button on the operator presses electric cabinet 11, the running of motor 12 transmits power to by driving pulley 13 and arbor 14 and drives disk 15, by driving disk 15 nylon wire on the nylon wire barrel 16 is wound on the center line on the center bar 18, cool off through moulding module 19 heating back, make left chain, right chain is compound and finish the slide fastener product.The schematic diagram of control circuit as shown in Figure 2 in its electric cabinet 11, starting switch makes the excitatory start of electromagnetic switch MC2 after spreading out of CRANK PULSES, connect the

contact

13 and 14,1 and 2,3 and 4,5 and 6 of electromagnetic switch MC2, directly control motor 12 entrys into service by electromagnetic switch MC2, press shutdown switch Stop and interrupt CRANK PULSES, make electromagnetic switch MC2 disconnect above-mentioned contact, stop motor 12 and remain in operation.Motor is a motor among Fig. 2, and F3, F4 are fuse, and MC1, MC2 are electromagnetic switch, and DL is the moving electric post of heat, and Power is a power switch, and Start is a starting switch, and Stop is a shutdown switch, and auto is hand/automatic switch.

At present, the motor 12 that adopts in this structure generally is the motor of 1.5KW, and output-current rating is 3.9A, the about 3.0A of actual operation output current.Because slide fastener has size specification, and the rotating speed of motor is fixed, so all be by changing the demand that the driving pulley speed ratio satisfies different speeds of production, this mode not only waste of energy is serious, and higher speed ratio accelerated the belt wearing and tearing, shortened the service life of belt, and, belt is changed trouble, bothersome, lacks change elasticity.
