The operation principle of the present invention is following (by taking one of doctor assemblies as an example, other doctor assemblies are same)：
Cylinder 33 drives rotary disk 35, rotary disk 35 to drive column 38, column 38 that workbench 1 is driven to rotate, until cutting
One of doctor assemblies 23 on charging tray 21 are directed at die cavity.Then driving rotating device (can be stepper motor or servo motor
Deng being not drawn into the lower section of middle shaft 39, figure) drive in shaft 39 rotate, middle shaft 39 is cut by transmission mechanism drive
Charging tray 21 rotates, and workbench 1 and gas distribution plate 22 are stationary at this time.
In 21 rotation process of blank disk：
First, the entrance of the first stomata 211 connects with exhaust passage 221 (position in Fig. 7 near first row stomata 228)
Logical, the entrance of the second stomata 212 is connected with inlet channel 222, and the air pressure in the second stomata 212 at this time is far above the first stomata
Air pressure in 211 so that mandril 232 slides into upper end in copper sheathing 231, and scraper 233 forms scraper notch (as shown in Figure 5),
In 21 rotation process of blank disk, the scraper notch scraper on scraper 233, until the scraper 233 is directed at die cavity, at this point, the first gas
The entrance in hole 211 is directed at the first air admission hole 225, and first concave ring 223 is most on the entrance alignment exhaust passage 221 of the second stomata 212
Internal vertex, the moment, the air pressure in the first stomata 211 is far above the air pressure in the second stomata 212 so that mandril 232 exists
Slide downward in copper sheathing 231 will expect to be pushed into die cavity from the scraper notch on scraper 233.
Then, blank disk 21 is rotated further, and the entrance of the first stomata 211 connects again with exhaust passage 221, the second stomata
212 entrance is connected with inlet channel 222, and mandril 232 slides into upper end in copper sheathing 231, when the first above-mentioned stomata 211
Entrance is gone to when being connected with third air admission hole 227, at this point, the second concave ring on the entrance alignment exhaust passage 221 of the second stomata 212
224 inner most vertex, the moment, the air pressure in the first stomata 211 is again far above the air pressure in the second stomata 212 so that top
The slide downward in copper sheathing 231 of bar 232.This action purpose be：If blanking is not when the doctor assemblies pass through die cavity position
Success, i.e. material are still remained in the scraper notch of scraper 233, then the material being hardened will be released scraper notch by the action again
(falling into returnable), to ensure following normal feeding.Therefore the corresponding mechanism of the action is set, in order to reduce
Rejection rate.
So far, an entire exercise is completed.
The preferred embodiment of the present invention described in detail above.It should be appreciated that those of ordinary skill in the art without
Creative work is needed according to the present invention can to conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution should all be fallen within the scope of protection of the present invention.
