Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-frequency heat-sealing machines, and specifically relates to a high-frequency heat-sealing machine for powder puff edge sealing. Background Art
[0002] The edge sealing of powder puffs can be processed using a high-frequency heat-sealing machine. A high-frequency heat-sealing machine is a device that uses high-frequency electrical energy to generate heat and heat-seal and seal plastics and other materials through a mold. This machine is suitable for heat-sealing and welding of various materials, including materials containing a certain proportion of PVC components. Therefore, it can be used to seal the edges of powder puffs, especially those powder puff products with plastic frames.
[0003] Common high-frequency heat-sealing machines include a stamping mechanism, a guide rail, and a mold. During use, the mold is driven by the guide rail to move under the stamping mechanism, and then the heat-sealing stamping seat is driven to descend by a cylinder to heat-seal and seal the powder puff raw materials inside the mold. However, since the mold is installed with multiple groups of bolts in this way, and when the high-frequency heat-sealing machine performs heat-sealing, sealing and other processing of different shapes, the corresponding mold needs to be replaced. Therefore, when replacing the mold, not only tools are required, but also the disassembly and assembly of multiple groups of bolts are time-consuming and laborious, which cannot meet the working requirements of the high-frequency heat-sealing machine. For this reason, a high-frequency heat-sealing machine for powder puff edge sealing is proposed. Summary of the Utility Model

[0017] (III) Beneficial effects
[0018] Compared with the prior art, the present utility model provides a high-frequency heat sealer for powder puff edge sealing, which has the following beneficial effects:
[0019] For this high-frequency heat sealer for powder puff edge sealing, by clamping the fitting inside the limit clamping posts on the top of the mold table, and then rotating the handwheel to drive the rotation of the transmission block, the synchronous outward expansion of the lock head can be promoted, so that the four corners inside the fitting can be squeezed by the outside of the lock head, and then the fitting can be clamped tightly, thus completing the installation of the heat-sealing mold. When the heat-sealing mold needs to be replaced, just rotate the handwheel in the reverse direction so that the lock head loses support and retracts, and the heat-sealing mold can be disassembled and assembled, improving the convenience of disassembling and assembling the heat-sealing mold.
