Description

Technical Field

[0001] This utility model relates to the field of desiccant packaging processing, and in particular to a desiccant packaging bag sealing mold. Background Technology

[0002] Statistics show that approximately 35% of desiccant products require three-dimensional hanging placement using hanging holes in specific applications such as electronic devices and warehouse shelves. However, this requirement faces significant challenges in actual production due to limitations in the design and manufacturing of existing molds. To ensure that desiccant products meet the hanging requirements in practical use, a secondary processing step using punching equipment is generally necessary after the packaging process to create the required hanging holes.

[0003] However, this seemingly simple secondary processing actually hides numerous problems and risks. First, from the perspective of stress distribution, due to the characteristics of the current edge-sealing process, the stress distribution in the edge-sealing area is not uniform. Especially when using equal-width edge sealing, detailed analysis and calculations revealed that the overlap rate between the punching points and the edge-sealing area is as high as 60%. The direct consequence of this high overlap rate is that during the punching operation, the impact force and stress on the edge-sealing area vary greatly, easily leading to a series of serious problems. The most prominent of these is the leakage of desiccant due to encapsulation damage. To verify the severity of this problem, laboratory test results showed that under these process conditions, the desiccant leakage rate is as high as 8.5%. This not only seriously affects product quality but may also pose potential safety hazards to the operating environment and related equipment.

[0004] Besides product quality issues, this secondary processing also negatively impacts production efficiency and costs. Firstly, secondary processing requires independent punching equipment, which occupies a significant amount of space on the production line. Actual measurements and estimates suggest this occupies approximately 15%-20% of the production line space. This undoubtedly increases the difficulty of production line layout and limits further expansion of production scale. Secondly, secondary processing requires manual intervention, reducing the automation level of the entire production process. Manual operation not only increases labor costs but is also susceptible to human factors, making it difficult to guarantee the stability and consistency of the production process. Statistics show that after such secondary processing, the overall production efficiency of a single production line decreases by 25%-30%, meaning that product output drops significantly within the same timeframe, thereby increasing production costs.

[0005] Therefore, existing technologies still need to be improved and enhanced. Utility Model Content

[0038] like Figure 1 and Figure 2As shown, this utility model provides a desiccant packaging bag sealing mold, including a base 11 and a mold head 12.

The desiccant packaging bag sealing mold provided by this utility model can be used on a sealing machine to simultaneously realize edge sealing, edge cutting, and hanging groove processing in one process. Punching can be completed in the sealing process, eliminating the need for an additional punching process, which not only saves labor and equipment costs but also greatly improves production efficiency.

[0039] Furthermore, in the desiccant packaging bag sealing mold provided by this utility model, the mold head 12 is equipped with two cutting grooves 18, and both the groove cutting head 14 and the cross-cutting blade 16 have fixing seats 19. The fixing seats 19 of the groove cutting head 14 and the cross-cutting blade 16 are detachably installed in the two cutting grooves 18. Furthermore, in the desiccant packaging bag sealing mold provided by this utility model, the bottom end of the cutting groove 18 matches the shape of the groove cutting head 14 or the cross-cutting blade 16. This embodiment uses a V-shaped blade, and the cross-cutting blade 16 is integrally formed with the fixing seat 19. There are cross-cutting blades 16 at both the top and bottom ends, which can be fitted and installed with the cutting grooves 18, and the blade head can be easily replaced.

[0040] Furthermore, in the desiccant packaging bag sealing mold provided by this utility model, screw holes 20 are provided on both sides of the mold head 12, and the screw holes 20 on both sides are respectively connected to the cutting grooves 18 on the adjacent side. In this embodiment, the two cutting grooves 18 are respectively fixed by screws through two pairs of screw holes 20. Furthermore, in the desiccant packaging bag sealing mold provided by this utility model, the mold head 12 is provided with a heating part for supplying heat to the first heat sealing zone 13, the middle heat sealing zone 15 and the tail heat sealing zone 17. Furthermore, in the desiccant packaging bag sealing mold provided by this utility model, the heating part includes two heating tubes 21, the heating tubes 21 are located below the sealing and cutting surface, and the heating tubes 21 are arranged parallel to the cross-cutting blade 16. Furthermore, in the desiccant packaging bag sealing mold provided by this utility model, one heating tube 21 is arranged close to the first heat sealing zone 13 and the middle heat sealing zone 15, and the other heating tube 21 is arranged close to the middle heat sealing zone 15 and the tail heat sealing zone 17. This invention can achieve temperature zone control through two heating tubes 21.

[0041] Specifically, the desiccant packaging bag sealing mold provided by this utility model has a mold head 12 that is a rectangular block. The sealing surface is located on the bottom surface of the mold head 12. The first heat sealing area 13, the groove cutting head 14, the middle heat sealing area 15, the cross cutting blade 16, and the tail heat sealing area 17 are arranged sequentially along the short side. The length of the cross cutting blade 16 is equal to the length of the mold head 12, while the length of the groove cutting head 14 is relatively short. The two long sides of the sealing surface have rounded corners. The surfaces of the first heat sealing area 13, the middle heat sealing area 15, and the tail heat sealing area 17 are provided with a wavy textured surface to improve the sealing effect. The base 11 is plate-shaped. The side of the base 11 is fixedly connected to the top of the mold head 12. The base 11 and the mold head 12 are integrally formed. The base 11 is provided with at least one pair of fixing holes 22. Furthermore, in the desiccant packaging bag sealing mold provided by this utility model, the width of the middle heat-sealing zone 15 is greater than the width of the first heat-sealing zone 13 and the tail heat-sealing zone 17. Furthermore, in the desiccant packaging bag sealing mold provided by this utility model, the width of the middle heat-sealing zone 15 is 1.2 to 1.5 times the width of the first heat-sealing zone 13 or the tail heat-sealing zone 17. This differentiated sealing width increases tensile strength by 50% compared to equal-width sealing, with a breaking load reaching 8 N / mm². This utility model, through three combined heat-sealing zones and a widened middle heat-sealing zone 15, can achieve differentiated sealing of long and short sides, and asymmetrical heat sealing of long and short sides (standard long-side sealing + reinforced short-side sealing). By coupling a cutting component in a single heat-sealing process, it innovatively achieves a three-fold combined process of heat-sealing forming, tensile structural reinforcement, and hanging slot precision machining, completely eliminating the secondary punching step; and effectively reducing the risk of packaging damage, enabling the desiccant product to directly have a hanging use function. The overall process efficiency is improved by more than 40%, and production costs are reduced by approximately 30%. This utility model can be used on pillow-type packaging machines. The desiccant packaging bag packaging mold automatically seals, cuts, and punches the packaging bags on the production line below by rotating. The rotation direction is consistent with the production line direction. During the rotation, the heat sealing area 13 to the tail heat sealing area 17 are pressed against the processing surface in sequence. This heat sealing module and integrated die are integrated into one unit, so that when the cutter cuts the film material, the force at each point is uniform, which helps to avoid damage to the film material.

[0042] In summary, this invention, through its three combined heat-sealing zones and a widened central heat-sealing zone, enables differentiated sealing of long and short sides, and asymmetrical heat sealing (standard long-side packaging + reinforced short-side packaging). By coupling a cutting assembly within a single heat-sealing process, it innovatively achieves a three-fold combined process of heat-sealing, tensile structural reinforcement, and precision machining of the hanging slot, completely eliminating the secondary punching step. Furthermore, it effectively reduces the risk of packaging damage, allowing desiccant products to be used directly in a hanging configuration. Overall process efficiency is improved by over 40%, and production costs are reduced by approximately 30%.
