Problems solved by technology

The bag body is clamped by the bag clamping mechanism and then transported to the station of the heat-sealing mechanism, and then the bag body is heat-sealed by the heat-sealing mechanism. This method has the following problems: when the existing bag body is stretched, it can only be stretched upwards. Half part, and the lower part is still easy to be adsorbed together due to the existence of static electricity. At this time, when filling the bag body, the bottom part may not be able to fill the material

Embodiment 1

[0037] Such as Figure 1 to Figure 12 As shown, the general fresh-keeping bag heat-sealing device is composed of two parts, two bag-clamping mechanisms 1 and two heat-sealing mechanisms 2 arranged in mirror images. 2. The heat-sealed bags 3 can be close to each other, and the bags 3 can be separated from each other after the heat-sealing is completed, and the bags 3 can be filled with material after the bags 3 are opened. The bag body 3 is clamped by the bag clamping mechanism 1 and then transported to the station of the heat-sealing mechanism 2, and then the bag body 3 is heat-sealed by the heat-sealing mechanism 2. This method has the following problems: the existing bag body 3 is stretched At this time, only the upper part can be stretched, and the lower part is still easy to be adsorbed together due to the existence of static electricity. At this time, when filling the bag body 3, the bottom may not be able to fill the material, which will easily cause the bag body 3 mater...

Embodiment 2

[0059] On the basis of Embodiment 1, this Embodiment 2 also provides a heat-sealing method of a heat-sealing device for a fresh-keeping bag that is convenient for filling. A specific heat-sealing device for a fresh-keeping bag that is convenient for filling is the same as that of Embodiment 1. I won't repeat them here.

[0060] The specific heat-sealing method of the fresh-keeping bag heat-sealing device that is convenient for filling is as follows, turn the second cross bar 145 to adjust the distance between the two bag side plates 142; push the bag bottom plate 12 to slide through the first bag bag cylinder 15, Make the opposite two clamping blocks 143 clamp the bag body 3; push the bag clamping bottom rail 13 to slide through the second bag clamping cylinder 16, so that the clamped bag body 3 slides between the two stretching air nozzles 54; Stretch the air nozzle 54 to absorb the bag body 3; push the stretch air nozzle 54 to slide through the stretch cylinder 52 to make th...

Abstract

The invention relates to the technical field of bag making, in particular to a freshness protection package heat sealing device and heat sealing method facilitating material filling. The freshness protection package heat sealing device facilitating material filling comprises bag clamping mechanisms and heat sealing mechanisms, wherein the bag clamping mechanisms are suitable for clamping a bag body; the two heat sealing mechanisms are oppositely arranged and can slide oppositely and conduct heat sealing on the bag body; an opening support is erected between the two bag clamping mechanisms; a material filling hole is formed in the opening support; a liftable material guide pipeline is arranged on the upper end surface of the opening support; the material guide pipeline is funnel-shaped; the cross section area of the material guide pipeline is gradually reduced from top to bottom; and the material guide pipeline extends into the material filling hole. After the bag body is opened, the material guide pipeline descends to extend into the bag body, the material guide pipeline is deformed by extruding the material guide pipeline to compress air, the compressed air blows air to the bag body, and the bottom of the bag body is also opened, so that the bag body is ensured to be completely opened, and the situation that materials overflow is avoided.

Description

technical field [0001] The invention relates to the technical field of bag making, in particular to a fresh-keeping bag heat-sealing device and heat-sealing method that are convenient for filling. Background technique [0002] The general fresh-keeping bag heat sealing device is composed of two parts, two bag clamping mechanisms set in mirror image and two heat sealing mechanisms set in mirror image. The bag body can also be separated from each other after the heat sealing is completed, and the bag body can be filled with material after the bag body is stretched. The bag body is clamped by the bag clamping mechanism and then transported to the station of the heat-sealing mechanism, and then the bag body is heat-sealed by the heat-sealing mechanism. This method has the following problems: when the existing bag body is stretched, it can only be stretched upwards. The half part and the lower part are still easy to be adsorbed together due to the existence of static electricity...
