Description

Technical Field

[0001] The invention relates to the technical field of stamp pad processing, in particular to a hot-melt stamp pad edge pressing device and a stamp pad pressing method thereof. Background Art

[0002] In order to meet the ever-increasing material performance requirements, seal pads made of thermoplastic mixed materials are developing towards environmental protection, high strength, wear resistance, stability and aging resistance. Many of the current seal pads are pressed using edge pressing equipment, which heats and presses them into shape during the pressing process.

[0003] In the traditional process, the punching equipment, the shaping mold and the forming and pressing die are separated. The machine and the mold need to be preheated, and the shaping mold and the processed seal pad material need to be manually aligned, which takes a long time of 1 minute. The seal pad material may shrink due to the temperature difference caused by the handover of the process. The final forming and pressing pad is punched again with a die, which causes errors and a high defective rate. Most of the products on the market do not use thermal insulation film in the production process, but directly press the steps. The steps of the seal pads are angular, and ink is easily seeped at the edges during the stamping process. Summary of the invention

[0041] The heat-insulating film mechanism is arranged between the stamping base plate 3 and the heating knife die 8 .

[0042] The thermal insulation film mechanism includes an isolation film support frame 9, which is fixedly connected to the fuselage 1. The right side of the isolation film support frame 9 is rotatably connected to a film delivery reel 10, and the left side of the isolation film support frame 9 is rotatably connected to a film collection reel 11. The isolation film support frame 9 is fixedly connected to the outside of the fuselage 1 by bolts.

The film collection reel 11 is provided with a power component. The arranged high temperature resistant isolation film 12 is wound on the film delivery reel 10 and the film collection reel 11. The unused high temperature resistant isolation film 12 is rolled on the film delivery reel 10, and the used high temperature resistant isolation film 12 is rolled on the film collection reel 11.

The two groups of bearing rollers 13 are symmetrically distributed on both sides of the isolation membrane support frame 9 to form support for the high-temperature resistant isolation membrane 12 .

[0067] Brackets are provided at both ends of the bearing drum 13, which are directly fixed to the isolation membrane support frame 9 by bolts, so that the height of the bearing drum 13 can be easily adjusted, so that the high temperature resistant isolation membrane 12 can be installed at a suitable position.

[0068] The heating knife die 8 is designed with a positioning notch groove 8011. For round seal products, a positioning notch processing design is added to the seal pad. The pressed hot-melt seal pad 4 has an anti-rotation positioning notch 401. The anti-rotation positioning notch 401 serves as a card point for positioning the seal shell to prevent the hot-melt seal pad 4 from shifting and rotating during use after it is inserted into the seal shell. In the implementation case, only one anti-rotation positioning notch 401 can achieve the positioning effect. The step groove 402 formed by the hot-melt seal pad 4 can ensure that the hot-melt seal pad 4 has a tighter fit with the seal surface table shell.
