Problems solved by technology

[0002] At present, the bag holding mechanism at the valve port adopts a mechanical bearing pad type external clamping structure. Since the clamping force is a mechanical hard force, it is easy to cause damage and rupture on the surface of the flexible material packaging bag. Secondly, when the bag is held by the bearing pad wrapping structure, The opening of the packaging bag is deformed greatly, which not only causes the volume of the packaging bag to become smaller, but also the sealing of the opening of the bag is poor, and the dusting phenomenon is serious

Embodiment Construction

[0008] In the figure: 1. Air bag, 2. Exhaust outer tube, 3. Air bag when inflated, 4. Discharge nozzle, 5. Inflated air flow, 6. Exhaust channel, 7. Air bag trachea, 8. Curved wall, 9, material, 10, valve pocket, 11, arc opening,

[0009] There is an exhaust outer pipe 2 outside the discharge nozzle 4, an exhaust passage 6 is formed between the discharge nozzle 4 and the exhaust outer pipe 2, and an air bag 1 is arranged outside the exhaust outer pipe 2, and the air bag 1 The two ends of the two ends are sealingly connected to the outside of the exhaust outer tube 2, and a trachea 7 for inflating the air bag 1 is arranged on the exhaust outer tube 2 corresponding to the air bag 1.

[0010] The outlet shape of the discharge nozzle 4 is: the upper wall is a downward curved arc wall 8, the outer end of the arc wall 8 is close to the center line of the discharge nozzle 4, and the lower part is an open arc opening 11. The structure helps the material to enter the valve pocket 10 f...

Abstract

The invention relates to the packing mechanism which is the air-cell swelling-sack holding structure used on the discharge mouth of the valve port balance. The air discharging pipes are out of the discharge mouth and between which and the pipe forms exhaust duct. The character is in that: the air cell is set besides of the exhaust pipe; the two ends of air cell are connected to the outside of exhaust pipe; the air pipe blowing to the air cell is set on the exhaust out pipe according to the air cell.

Description

technical field [0001] The invention relates to a packaging machine, in particular to an airbag expansion-holding bag-holding structure used on a discharge nozzle of a valve-port scale. Background technique [0002] At present, the bag holding mechanism at the valve port adopts a mechanical bearing pad type external clamping structure. Since the clamping force is a mechanical hard force, it is very easy to cause damage and rupture on the surface of the flexible material packaging bag. Secondly, when the bag is held by the bearing pad wrapping structure, The mouth of the packaging bag deforms greatly, which not only causes the volume of the packaging bag to become smaller, but also has poor sealing of the mouth of the bag and serious dusting. Contents of the invention [0003] The object of the present invention is to provide a bag-holding structure of a valve port scale air bag expansion type, so as to eliminate the residual gas remaining in the packaging bag during the pa...
