The utility model provides a point sealing mould for producing a gas column bag, which comprises a base 1, wherein the top of the base 1 is fixedly connected with a U-shaped plate 2, the bottom of the U-shaped plate 2 is provided with a fixed plate 3, the tops of the fixed plate 3, which are close to two sides, are slidably inserted with limiting rods 4, the tops and the bottoms of the limiting rods 4 are fixedly connected with the top in the U-shaped plate 2 and the top of the base 1 respectively, the top of the fixed plate 3 is fixedly connected with a hydraulic rod 5, and the top of the hydraulic rod 5 is fixedly connected with the top in the U-shaped plate 2; the bottom of fixed plate 3 is equipped with two strip of paper used for sealing 6, two the screw thread runs through to peg graft between the strip of paper used for sealing 6 has same screw rod 7, the bottom of strip of paper used for sealing 6 has linked firmly a plurality of archs 8, and the top of strip of paper used for sealing 6 has linked firmly a plurality of sliders 9, and the top of slider 9 corresponds the spout has been seted up to fixed plate 3 bottom, and slider 9 is located the spout, is located two of same spout one side that slider 9 is relative all runs through and has seted up bar hole 10, current two it has same slide bar 11 to slide to run through to peg graft between the bar hole 10, and the slide bar 11 screw thread runs through to peg graft at the rear side of fixed plate 3, be equipped with closing device 12 in the bar hole 10.

As shown in fig. 2 and 3, the pressing device 12 includes an arc-shaped plate 121, the top of the arc-shaped plate 121 is fixedly connected with two telescopic rods 122, the top of each telescopic rod 122 is fixedly connected with the top hole wall of the corresponding strip-shaped hole 10, the telescopic rods 122 are sleeved with springs 123, and the springs 123 are always in a compressed state.

As shown in fig. 2 and 4, a supporting ring 13 is attached to the top of the seal 6, the supporting ring 13 encloses the plurality of sliders 9, and balls 14 are mounted on the top of the supporting ring 13 and the bottom of the arc-shaped plate 121; the support ring 13 can ensure the support area of the top of the seal 6 and the bottom of the fixing plate 3, and the balls 14 on the top of the support ring can reduce the friction force applied to the seal 6 during the movement process.

As shown in fig. 2, the screw threads of the opposite portions of the screw 7 and the two seals 6 are designed in an opposite manner, and nuts 15 are respectively sleeved on the screw threads 7 corresponding to the opposite sides of the two seals 6; the threads with the opposite design can enable the two seals 6 to be close to each other under the action of the screw 7 when the screw 7 is rotated, and after the two seals 6 move to proper positions, the nut 15 can be screwed to enable the two seals 6 to be locked at the current positions, so that the seals 6 are prevented from shaking due to frequent touch.

As shown in fig. 2 and fig. 3, a gap is always formed between the bottom hole wall of the strip-shaped hole 10 and the bottom of the sliding rod 11, and the width of the strip-shaped hole 10 is equal to the diameter of the sliding rod 11; during the movement of the slider 9 along the sliding rod 11, the spring 123 always exerts a downward pressure on the arc-shaped plate 121, so that the support ring 13 can always keep a tight fit with the bottom of the fixed plate 3.

As shown in fig. 5, the protrusions 8 on the two seals 6 are staggered from each other, and the diameter of the bottom of the protrusion 8 is five millimeters; mutual staggered arch 8 can be when sealing a little the gas column bag, make the position of admitting air of two adjacent gas columns stagger, thereby when the gas column is full of gas, be located 1 fore-and-aft direction of base and be located the stress point of a plurality of sealed points on the collinear can not be on same straight line, and then avoid a plurality of sealed points on the collinear to be propped open or damaged because of the atress is too big, five millimeters point seal the diameter in addition and seal the diameter for traditional seven millimeters point, can reduce the resistance that the gas column bag received when aerifing, and then improve the inflation efficiency of gas column bag.

As shown in fig. 2 and 4, the balls 14 on the top of the supporting ring 13 do not contact with the sliding groove, and the balls 14 can closely fit with the bottom of the fixing plate 3; the closely attached balls 14 can ensure that the support ring 13 keeps a stable moving state during the moving process, and meanwhile, when the seal 6 is in contact with the base 1, the seal 6 can also keep a stable state.

The working principle is as follows: when the packaging bag is point-sealed, the distance between the two sealing strips 6 is adjusted according to the specification of the air column bag, during adjustment, the screw 7 is rotated, because the threads at the opposite positions of the screw 7 and the two sealing strips 6 are designed oppositely, when the screw 7 is rotated, the two sealing strips 6 are driven by the screw 7 to gradually approach each other, in the process, the two sliders 9 on the same slide bar 11 slide along the same slide bar 11, so that the arc-shaped plate 121 is driven by the sliders 9 to move close to the top of the slide bar 11, and because the spring 123 is always in a compression state, the spring 123 enables the support ring 13 to be tightly attached to the bottom of the fixed plate 3 through the pressure on the arc-shaped plate 121 and the slide bar 11, so that the sealing strips 6 are kept in a stable movement state under the support effect of the support ring 13, and when the packaging bag is adjusted to a proper position, the screw 7 is stopped to rotate, then, the two screw caps 15 are rotated to enable the two screw caps 15 to be tightly squeezed with the sides, away from the two seals 6, of the two seals 6 respectively, so that the positions of the two seals 6 are locked, when point sealing operation is carried out, the hydraulic rod 5 extends, the fixing plate 3 drives the two seals 6 to move downwards simultaneously and to be in contact with the base 1, and therefore a packaging bag on the base 1 can be pressed out of the shape of an air column under the pressing action of the protrusions 8 at the bottoms of the two seals 6, and the point sealing efficiency is improved due to the fact that the two seals 6 are arranged;

meanwhile, the mutually staggered bulges 8 can stagger the air inlet positions of two adjacent air columns when point sealing is carried out on the air column bags, so that when the air columns are filled with air, the stress points of a plurality of sealing points which are positioned in the front-back direction of the base 1 and on the same straight line can be different on the same straight line, and the sealing points on the same straight line are prevented from being opened or damaged by air due to overlarge stress;

in addition, compared with the traditional point sealing diameter of seven millimeters, the point sealing diameter of five millimeters can reduce the resistance of the air column bag during inflation, and further improve the inflation efficiency of the finished air column bag.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
