DETAILED DESCRIPTION

[0017] The technical solution of the present utility model is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0018] like Figures 1 to 3As shown, a punching device for mask production comprises a machine base 1 and a machine head 2 mounted on the machine base 1, a punching base 3 is mounted on the top surface of the machine base 1, a punching groove 4 is provided on the top surface of the punching base 3, a punching shaft 5 is vertically connected to the punching head of the machine head 2, a punching die knife 6 is connected to the bottom of the punching shaft 5, a limit pressing plate 7 is movably sleeved on the punching die knife 6, the bottom surface of the limit pressing plate 7 is lower than the bottom surface of the punching die knife 6, a mounting plate 8 is fixedly sleeved on the punching shaft 5, the mounting plate 8 is connected to the limit pressing plate 7 through a plurality of elastic members, and the mask original cloth is conveyed through the conveying The feeding mechanism or the traction mechanism drives it to move, and the mask original cloth passes through the top of the punching base 3, and then the shape of the mask original cloth is punched by the punching die knife 6 that moves up and down. During the punching process, the limiting pressure plate 7 first contacts the mask original cloth, and the reaction force of the elastic member makes the limiting pressure plate 7 press the non-punching area of ​​the mask original cloth. On the one hand, the mask original cloth is limitedly punched to ensure the punching quality, and on the other hand, the mask original cloth is kept in a taut state to ensure the punching effect, thereby reducing the defective rate and improving the production quality and production efficiency.

[0019] Furthermore, a plurality of limiting cones 9 are fixed to the bottom of the limiting pressure plate 7. The limiting cones 9 pass through the original mask cloth and contact the punching base 3, thereby strengthening the limiting effect on the original mask cloth and further preventing deviation during the punching process.

[0020] Furthermore, if Figure 1 and Figure 2 As shown, the elastic member includes a telescopic rod 10 and a spring 11. The two ends of the telescopic rod 10 are respectively connected to the mounting plate 8 and the limiting pressure plate 7. The spring 11 is sleeved on the telescopic rod 10. The two ends of the spring 11 are respectively connected to the mounting plate 8 and the limiting pressure plate 7. After the limiting pressure plate 7 contacts the original cloth of the mask, the punching shaft 5 drives the punching die knife 6 to continue to move downward to complete the punching. At this time, the spring 11 will be compressed, and the reaction force of the spring 11 is used to make the limiting pressure plate 7 press the original cloth of the mask.

[0021] In some embodiments, Figure 2As shown, the punching die knife 6 includes a mounting body 12 and a die knife body 13. The top of the mounting body 12 is connected to the punching shaft 5 through a flange. A threaded column 14 is coaxially fixed to the bottom of the mounting body 12. A threaded hole 15 is provided on the top of the die knife body 13. The threaded column 14 is threadedly adapted in the threaded hole 15. The punching die knife 6 can be partially replaced, which reduces the cost. When masks of different sizes need to be produced or the die knife body 13 is worn, the die knife body 13 needs to be replaced. The die knife body 13 is connected to the mounting body 12 by threads, which is simple to install and convenient for replacing the die knife body 13. A plug-in shaft is coaxially fixed to the end of the threaded column 14 away from the mounting body 12 16, a plug hole 17 is penetrated through the side wall of the plug shaft 16, and the plug shaft 16 is adapted in the threaded hole 15. A plug hole 18 is penetrated through the side wall of the mold cutter body 13 at a position corresponding to the plug hole 17. A bolt 19 is arranged on the mold cutter body 13, and the bolt 19 passes through the plug hole 18 and the plug hole 17 at the same time. In order to strengthen the connection between the mounting body 12 and the mold cutter body 13, the bolt 19 is added. When the mounting body 12 and the mold cutter body 13 are screwed, the plug hole 17 and the plug hole 18 correspond coaxially. At this time, the bolt 19 is passed through the plug hole 17 and the plug hole 18, and finally the nut is screwed on to complete the tooling of the mold cutter body 13, with a stable structure and high connection strength.

[0022] In some embodiments, Figure 1 and Figure 3 As shown, an external threaded column 20 is vertically fixed on the top of the machine base 1, and an internal threaded hole 21 is opened at the bottom of the punching base 3. The external threaded column 20 is threadedly adapted in the internal threaded hole 21, and the bottom fixed sleeve of the punching base 3 is provided with a mounting base plate 22. When the external threaded column 20 is threadedly adapted in the internal threaded hole 21, the mounting base plate 22 is connected to the machine base 1 by screws. When producing masks of different sizes, the punching base 3 of the corresponding size needs to be replaced. During installation, the punching base 3 is first threadedly tightened on the external threaded column 20, and finally the mounting base plate 22 is connected to the machine base 1 by screws. At this time, the punching base 3 has a high connection strength and meets the continuous punching strength requirements.
