Problems solved by technology
[0004] However, in Patent Document 1, when the position in the direction perpendicular to the conveying direction of the conveyed powder-filled packaging bag is misaligned, the sealing part and the heater will not come into complete contact, and sealing failure will occur. The problem
In addition, in Patent Document 2, since the sealing part of the powder filled packaging bag being transported is heated by a movable heater, the heating time can be prolonged and the sealing accuracy can be improved. However, since the heater is installed on the powder In the direction perpendicular to the conveying direction of the body-filled packaging bag, the heater may have local poor contact with the sealing part, which may cause poor sealing.

The present invention provides a capper and a method for sealing powder filling packing bag, which heats the thermal crimping bonding layer of the sealing part of the packing bag filled with powder efficiently so as to sealing the powder filling packing bag. The powder filling packing bag is arranged with a thermal crimping bonding layer (102) on the sealing part (101), and be closed through heating the sealing part. The capper (10) comprises: a first transportation device (20) for transporting powder filling packing bag (100-1); a pose slant device (30) for slanting the pose of the powder filling packing bag transported by the first transportation device; a second transportation device (40) for transporting the powder filling packing bag with inclined pose; a contact adjusting device (50), comprising a contact part (51) which pressure contacts the sealing part (101) of the powder filling packing bag so as to heating or cooling the bonding layer (102), and ensure the contact part adjust contact time and / or contact area movably.
Description
technical field [0001] The present invention relates to a sealing machine and a sealing method for a packaging bag filled with powder for sealing a sealing portion of a packaging bag filled with powder. Background technique [0002] A packaging bag filled with powder such as wheat flour has a thermocompression adhesive layer on the sealing part, and the sealing part is heated to melt the adhesive layer to seal. In order to seal the sealing portion of such a powder-filled packaging bag, sealing machines having various mechanisms have been proposed. (Example: Patent Document 1 and Patent Document 2) [0003] The invention of Patent Document 1 is to seal the sealing portion of the powder-filled packaging bag by heating and cooling the sealing portion of the powder-filled packaging bag transported in an inclined state by using a heater fixed along the conveying direction. The invention of Patent Document 2 is a device with a solid structure, and the invention of Patent Documen...
