The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Please read Fig. 1, Fig. 2 and Fig. 3, of the present utility modelly collude colored twine forming machine, comprise and twisting around the forming rolls 1 that colludes colored twine, the exit of colluding colored twine at forming machine is provided with shearing device, this shearing device is made of the cutting knife 3 and the knife drive mechanism that are oppositely arranged, in described forming machine, also be provided with the counter 2 of metering forming rolls 1 rotating cycle, and be provided with travel switch 6 on described knife drive mechanism next door, described counter 2 is controlled to when reaching preset value that shape roller 1 stops and the knife drive mechanism action, and described travel switch 6 is controlled to 1 running of shape roller and counter 2 countings when described cutting knife 3 resets.

Consult Fig. 2, described knife drive mechanism comprises cutting knife resetting means and a pair of cam 4 that contacts with described cutting knife 3 respectively, described cutting knife resetting means is a reduction torsion spring 8, torsion spring 8 two ends are connected on the described cutting knife 3, the high point of the stroke of described cam 4 drives rotation synchronously toward each other and by transmission mechanism, the high point of cam position when described travel switch 6 (SQ1) is positioned at cutting knife 3 and is in deployed position.Identical and direction of rotation is opposite in the shape of two cams 4 described in Fig. 2.By decelerator, travelling gear or chain wheel drive, its transmission can be adopted known mode to cam 4, does not repeat them here by drive motors D2.Described knife drive mechanism also can be other reciprocating moving devices, as hydraulic cylinder, rack-and-pinion device or the like.Also be provided with second travel switch 7 (SQ2) that control cam 4 stops on described cam 4 next doors, this second travel switch 7 is provided with at interval with described travel switch 6, and described cam 4 contacts with second travel switch 7 with travel switch 6 successively.

As shown in Figure 1; electromagnetic brake 9 is housed on the driving shaft of described forming rolls 1; and electromagnetic clutch 5 is housed between described driving shaft and forming rolls 1 transmission device; the control circuit of described electromagnetic brake 9 and electromagnetic clutch 5 (referring to Fig. 3) interlocked with one another, described counter 2 and travel switch 6 are controlled stopping of forming rolls 1 by the break-make of control electromagnetic brake 9 and electromagnetic clutch 5 or are changeed.Described counter can be the Hall counter, it comprises metal salient point 21 and the corresponding inductor that is arranged on described forming rolls 1 driving shaft both sides, adopting two metal salient points is to collude colored twine in order to produce half-turn, and above-mentioned Hall counter can have been bought on market.

Referring to Fig. 1, Fig. 3, the operation principle of forming machine of the present utility model is as follows:

Iron wire is inserted thread eye to be pressed on the forming rolls 1 with the silk pressing wheel again, master switch QS closes, B3 is incorporated into the operating position switch S, start SB2, relay K M1 connects and self-locking, relay K M2 connects simultaneously, forming rolls 1 drive motors D1 and cut-out motor D 2 get electric rotation, driving cam 4 rotations also drive cutting knife generation cut-out action, and do not move owing to travel switch SQ1 this moment, not adhesive of auxiliary reclay KA2, not adhesive of electromagnetic clutch relay L, electromagnetic brake ZJ adhesive, forming rolls 1 does not rotate, supplies silk.

When cam 4 continues rotation and contacting travel switch S Q1, auxiliary reclay KA2 adhesive makes electromagnetic clutch relay L adhesive, and electromagnetic brake relay ZJ outage, forming rolls 1 rotation is for silk, and unison counter JS adhesive begins counting.

When cam 4 continues rotation and contacts the second travel switch SQ2, auxiliary reclay KA1 adhesive, relay K M2 outage is cut off drive motors D2 and is stopped, and cam 4 stops operating.

When counter 2 arrives predetermined count value adhesive, auxiliary reclay KA1 disconnects, the KA3 adhesive, make KA2 disconnect, electromagnetic clutch relay L cuts off the power supply at this moment, electromagnetic brake relay ZJ adhesive---forming rolls 1 stops, and relay K M2 adhesive---cut off motor D 2 rotations, drive 3 generations of cam 4 driving cutting knifes and cut off action.

Cam 4 continues rotation contacting travel switch S Q1, begins next working cycles.

In Fig. 3, trip switch SB3, make electromagnetic brake outage after, can manually adjust the position of rotation of forming rolls 1.

With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment the protection domain that all any improvement done based on the utility model or modification all belong to the utility model claim.
