Detailed Description

The invention is further illustrated by the following specific embodiments.

As shown in fig. 1, the double-helix transverse sealing mechanism includes a vertically arranged main body plate 9, two sides of the main body plate 9 are a transverse sealing side and a power side respectively, the power side is provided with a speed reducer 1, a servo motor 2, a synchronous belt 3, a driving wheel 4, an idle wheel 41 and a driven wheel 42, the servo motor 2 is connected with the driving wheel 4 and drives the driving wheel 4 to rotate, in this embodiment, the servo motor 2 is connected with the driving wheel 4 through the speed reducer 1, and the speed reducer 1 is fixed on the main body plate 9.

The synchronous belt 3 is sleeved on the driving wheel 4, the idle wheel 41 and the driven wheel 42; in this embodiment, the number of the driven wheels 42 is two, the number of the idle wheels 41 is two, the two driven wheels 42 are disposed on the inner sides of the two idle wheels 41, the driving wheel is driven by the servo motor 2 to rotate, the two idle wheels 41 are driven to rotate in the same direction, and the idle wheels 41 drive the two driven wheels 42 to rotate in the same direction through the synchronous belt 3.

Violently the side is provided with screw nut 5, interior violently seal 6, ball 7 and outer violently seal 8, ball 7's the inner run through the main part board 9 and with be connected from driving wheel 42, ball 7 still runs through interior violently seal 6 and outer violently seal 8, ball 7 is two positive and negative double helix form, there is screw nut 5 on interior violently seal 6 and the outer violently seal 8 fixed mounting respectively, and screw nut 5 cover is established on ball 7, when ball 7 rotated, screw nut 5 moves in opposite directions, thereby it accomplishes the action of opening and shutting to drive interior violently seal 6 and outer violently seal 8.

Servo motor 2 provides power, through reduction gear 1 effect, drive action wheel 4 rotates, action wheel 4 passes through hold-in range 3 and drives idler 41, and simultaneously, idler 41 passes through hold-in range 3 and drives from driving wheel 42 and be reciprocating motion, ball 7 the inner is connected with from driving wheel 42, from driving wheel 42 rotation, drive ball 7 reciprocating motion, ball 7 is positive and negative double helix form, above-mentioned both ends are equipped with screw nut 5, when ball 7 rotates, two screw nut 5 above-mentioned can be along ball 7 operation in opposite directions, make interior horizontal seal 6 and outer horizontal seal 8 accomplish the action of opening and shutting like this, finally accomplish the involution action of pillow bag.
