Corresponding position, each Scroll (1) end, one end is provided with the second control mechanism, second control mechanism includes and transmits dish A(2) and proximity switch A(3), transmit dish A(2) be fixedly mounted on first adapter shaft (26) of each Scroll (1) corresponding position, and rotate with gear A (9); Proximity switch A(3) be fixedly installed on side plate (162), and with transmit coil A(2) relative, transmit dish A(2) on be provided with a breach; In rotation process, transmit dish A(2) on breach go to proximity switch A(3) place, proximity switch A(3) sense transmit dish A(2) on breach, Scroll (1) stop motion.Now, bonding strip (20) on the outside face of the tube core (19) of Scroll (1), just facing to the joint present position of the upper film of friction roller (24), during to ensure friction roller (24) rotation work, the joint that press against film pastes on the bonding strip (20) of tube core (19); Thus when ensure that multistation change of lap (Scroll (1) repeats change of lap N time), when the Scroll (1) of different station connects film, film joint cumulative can be connected on the same position (bonding strip setting position) on Scroll, prevent rolling rear film from occurring the phenomenons such as wrinkle, reduce the generation of waste material, improve the quality of products.

A kind of wrap-up that can realize fixing a point to cut that the utility model provides, its principle of work is specific as follows:

The wrap-up that the utility model provides and cutter sweep, drive friction roller (24) co-operation of film, as shown in Figure 2, its rolling mode adopts surface friction rolling mode, and friction roller (24) present position is work station.

First, motor B(12) start, drive rolling frame (16) to rotate by worm-and-wheel gear (15), transmit dish B(17 simultaneously) rotate with main shaft (161); As proximity switch B(18) sense transmit dish B(17) on wherein after an induction pieces, rolling frame (16) stops operating, and the Scroll (1) now in rolling frame (1) moves to friction roller (24) present position place.

Then, starter motor A(11), motor A(11) drive Scroll (1) to rotate by the second transmission device, when proximity switch A3 senses the breach transmitted on dish A2 time, Scroll 1 stops operating, and the adhesive band (20) now on Scroll (1) is just relative with the film joint on friction roller (24); Friction roller (24) in the die surfaces of Scroll (1), and makes film joint be pressed on adhesive band (20) with thin film; Film joint is connected to after on adhesive band (20), friction roller (24) rotates, under the effect of friction force, drive Scroll (1) and tube core (19) rotate together, tube core (19) rotation thus on the tube core (19) that film take-up is arrived on Scroll (1);

Until the rolling of a tube core (19) completes, friction roller (24) quits work, restart motor B(12), make next Scroll from treating that work station goes to work station, and by cutter sweep (24), specified location (namely the ensure film interface position unified) cutting of film at work station is come; And then starter motor A(11), repeat above-mentioned steps.

When this cover design of mechanism that the utility model provides and mode can ensure multistation change of lap the rolling of different station be coupling film time can be connected on same position, ensure to connect the generation that the quality of film and efficiency reduce waste material.

Those skilled in the art should be understood that the utility model can realize with other concrete forms many and not depart from spirit or scope of the present utility model.Although described embodiment of the present utility model, the utility model should be understood and should not be restricted to these embodiments, within the utility model spirit and scope that those skilled in the art can define as appended claims, make change and amendment.
