Claims

[Claims for Utility Model Registration] A rotor 13 having a number of plates 15 vertically fixed around it is connected to a driving shaft 16 via an intermittent power transmission mechanism 17, and each plate is placed in the bag receiving position A.
, a vacuum position B, a sealing position C, and a bag release position D. A pair of sealing bars 27 is provided on each board 15, respectively.
, 28 are provided so that they can be opened and closed freely, and pins 45 for opening and closing each of these seal bars are hermetically penetrated through the plate 15 and protrude toward the center of the rotor, and the ends of each of the pins 45 are provided concentrically with the rotor. cam 4
7, and setting the shape of the cam 47 so that the pair of seal bars 27, 28 are opened in the bag release position D, and the pair of seal bars 27, 28 are in pressure contact with each other in other positions; Seal bar 2 on one side of each pair of seal bars
While fixing the receiving plate 35 to the seal bar 27 on the other side, a movable plate 38 with a corrugated tip is attached to the spring 4.
A shaft 48 for fixing the cam 47 is rotatably supported at the center of the rotor 13, and the shaft 48 and the drive shaft 16 are In the vacuum position B, a forward/reverse transmission mechanism 55 is interposed between the cam 47 and the rotor 13, so that after the cam 47 rotates together with the rotor 13, only the cam 47 is returned in the reverse direction by the already rotated angle. The cam 47
Forming a recess 47a in the guide surface of the pair of seal bars 27 and 28 to loosen the pressure contact between the pair of seal bars 27 and 28, and at the same position cover the disc 15 with a lid member 60 airtightly; At the seal position C, the pair of seal bars 27
, 28, and applying an impulse current to heater wires provided on opposing surfaces of the vacuum packaging apparatus.
