Description

Packaging mould for drying agent packaging bag Technical Field The utility model relates to the field of drying agent packaging processing, in particular to a drying agent packaging bag packaging mold. Background It is counted that about 35% of desiccant products are required to be placed in a specific scene such as electronic equipment, storage shelves and the like in a three-dimensional hanging manner by means of hanging holes in practical application scenes. This requirement presents a significant challenge in practical manufacturing processes because of the limitations of existing molds in design and manufacture. In order to ensure that the desiccant product can meet the hanging functional requirements in practical use, generally, after the packaging process is completed, a punching device is specially adopted to carry out secondary processing on the product so as to form a required hanging hole. However, this seemingly simple secondary process, in effect, conceals a number of problems and risks. First, from a stress distribution perspective, the stress distribution in the edge sealing area is not uniform due to the characteristics of the current edge sealing process. Particularly, in the case of adopting the equal-width edge sealing, detailed analysis and calculation show that the overlapping rate of the punching site and the edge sealing area is up to 60 percent. The direct consequence of this high overlap ratio is that the edge sealing area is subject to a large impact and stress variation during the punching operation, which is very prone to cause a serious set of problems. Most prominent among these is the case of package breakage resulting in desiccant leakage. To verify the severity of this problem, laboratory test results have shown that under these process conditions, the leakage rate of the desiccant is as high as 8.5% or more. This not only has a serious impact on the quality of the product, but also may present a potential safety hazard to the environment of use and associated equipment. In addition to product quality problems, this secondary process also has a negative impact on production efficiency and production costs. On the one hand, secondary processing requires the provision of separate punching equipment which takes up considerable space on the production line, with actual measurements and estimations taking up between about 15% and 20% of the production line space. This clearly increases the difficulty of the spatial layout of the production line and also limits further expansion of the production scale. On the other hand, the secondary processing process also needs manual intervention, so that the automation degree of the whole production process is reduced, the labor cost is increased by manual operation, the secondary processing process is easily influenced by human factors, and the stability and consistency of the production process are difficult to ensure. It is counted that after such secondary processing is performed on a single production line, the overall production efficiency is reduced by 25% -30%, which means that the yield of the product is greatly reduced in the same time, thereby increasing the production cost. Accordingly, there is a need for improvement and advancement in the art. Disclosure of utility model In view of the above-mentioned shortcomings of the prior art, an object of the present utility model is to provide a desiccant packaging mold. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides a packaging mould for a drying agent packaging bag, which comprises a base and a die head, wherein the die head is arranged on the base, the die head is provided with a sealing surface, the sealing surface comprises a first heat sealing area for sealing the packaging bag, a groove cutting end for cutting a hanging groove, a middle heat sealing area for sealing the packaging bag, a transverse cutter for dividing front and rear packaging bags and a tail heat sealing area for sealing the packaging bag, and the first heat sealing area, the groove cutting end, the middle heat sealing area, the transverse cutter and the tail heat sealing area are sequentially arranged. Further, the drying agent packaging bag packaging mold is characterized in that two cutter grooves are formed in the mold head, the groove cutting heads and the transverse cutters are respectively provided with a fixing seat, and the fixing seats of the groove cutting heads and the transverse cutters are respectively detachably arranged in the two cutter grooves.
