Detailed Description

The invention is further described below with reference to the accompanying drawings:

as shown in fig. 1, the present embodiment includes a housing 6, an air pump 2, an air tube 8, and feed rollers 10 provided in pairs for feeding. The above is a common structure in the prior art, and is not described herein again.

As shown in fig. 1 and 2, the present invention further includes sealing rollers 5 disposed in pairs, and the outer surfaces of the sealing rollers 5 are cylindrical surfaces. Under the compressing action of the sealing roller 5, the inflation air passage at the edge of the air column film 7 is blocked, so that the air column film 7 between the sealing roller 5 and the heat sealing roller 9 is inflated, the gas in the inflation air passage of the air column film 7 is prevented from leaking to the deeper part of the air passage, and the problem of insufficient or uneven inflation is further solved.

As shown in fig. 1 and 3, the air pump 2 is installed inside the housing 6, the structure of the air pump 2 includes a piston cylinder 13, a piston body 14, an eccentric wheel and a driving shaft 17, the piston body 14 is slidably installed inside the piston cylinder 13, the eccentric wheel is installed inside the piston cylinder 13 and installed on the driving shaft 17, the axis of the driving shaft 17 is perpendicular to the movement direction of the piston body 14, the driving shaft 17 is driven by the motor 1, two ends of the piston cylinder 13 are respectively provided with an air inlet check valve 11 and an air outlet check valve 12, and the air discharged from the two air outlet check valves 12 is collected by a pipeline and then discharged through the end of the air charging pipe 8. The invention adopts the air pump 2 driven by the eccentric wheel, and the air pumping quantity of one unidirectional stroke of the piston body 14 in the air pump 2 can be equal to the air charging quantity required by a single air column by adjusting the eccentric distance of the eccentric wheel, thereby realizing the one-by-one air charging by taking the single air column as a unit.

The end of the driving shaft 17 extends to the outside of the piston cylinder 13, and the end of the driving shaft 17 is connected with the rotating shaft of the feed roller 10 through a pair of synchronous pulleys 3 and a belt 4. In the invention, the air pump 2 and the feeding roller 10 adopt the same motor 1 as a power source, and absolute synchronization of the inflation speed and the feeding speed can be realized by adjusting the stroke range of the piston body 14 in the air pump 2 and the transmission ratio of the synchronous belt wheel 3, so that the matching precision of the inflation speed and the feeding speed of the air column film 7 is fully ensured, and the problem of insufficient or uneven inflation is avoided.

As shown in fig. 4, the inflation tube 8 is sandwiched between a pair of feeding rollers 10, the end of the inflation tube 8 is located between the feeding rollers 10 and the sealing roller 5, the sealing roller 5 is mounted on a wheel frame 19, a lead screw 18 is connected to the wheel frame 19, the lead screw 18 is connected to the housing 6 through a screw thread, and the adjustment of the distance between the sealing roller 5 and the heat-sealing roller 9 can be realized by screwing the lead screw 18. Through the interval of adjustment seal roller 5 and heat-seal gyro wheel 9, make this interval equal to the width of an air column to aerify one by one the air column on the air column membrane 7, can reduce equipment by a wide margin and open the not enough air column quantity of aerifing that stops the linking department. Meanwhile, the adjustment of the distance between the sealing roller 5 and the heat-sealing roller 9 can adapt to the air column films 7 with different air column widths and various specifications.
