Operation principle of the present utility model following (as a example by one of them doctor assemblies, other doctor assemblies phase therewith With):

Cylinder 33 drives rotary disk 35, rotary disk 35 to drive column 38, column 38 to drive work platforms 1 to rotate, until cutting One of them doctor assemblies 23 on charging tray 21 is directed at die cavity.Then driving rotary apparatus (can be motor or servomotor Deng, it is positioned at the lower section of shaft 39, figure is not drawn into) drive shaft 39 to rotate, shaft 39 is driven by drive mechanism and cuts Charging tray 21 rotates, now work platforms 1 and the equal transfixion of gas distribution plate 22.

In blank dish 21 rotation process:

First, the entrance of the first pore 211 and exhaust passage 221 (in Fig. 7 position) near first row pore 228 even Logical, the entrance of the second pore 212 connects with inlet channel 222, and now the air pressure in the second pore 212 is far above the first pore Air pressure in 211 so that push rod 232 slides into upper end in copper sheathing 231, scraper 233 forms scraper breach (as shown in Figure 5), In blank dish 21 rotation process, the scraper breach scraper on scraper 233, until this scraper 233 is directed at die cavity, now, the first gas The entrance in hole 211 is directed at the first air inlet 225, and on the entrance of the second pore 212 alignment exhaust passage 221, the first scrobicular ring 223 is Internal summit, in this moment, the air pressure in the first pore 211 is far above the air pressure in the second pore 212 so that push rod 232 exists Slide downward in copper sheathing 231, pushes die cavity by material scraper breach from scraper 233.

Then, blank dish 21 is rotated further, and the entrance of the first pore 211 connects with exhaust passage 221 again, the second pore The entrance of 212 connects with inlet channel 222, and push rod 232 slides into upper end in copper sheathing 231, when the first above-mentioned pore 211 When entrance goes to connect with the 3rd air inlet 227, now, the second scrobicular ring on the entrance alignment exhaust passage 221 of the second pore 212 224 inner most summits, in this moment, the air pressure in the first pore 211 is again far above the air pressure in the second pore 212 so that top Bar 232 is slide downward in copper sheathing 231.The purpose of this action is: if this doctor assemblies is through the blanking of die cavity position not Success, in i.e. material still remains in the scraper breach of scraper 233, then hardening material will be released scraper breach by this action again (falling in returnable), to guarantee the most normal feeding.Therefore mechanism corresponding to this action be set in order to reduce Percent defective.

So far, an entire exercise is completed.

Preferred embodiment of the present utility model described in detail above.Should be appreciated that the ordinary skill people of this area Member just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technology neck In territory, technical staff passes through logical analysis, reasoning or limited reality on the basis of existing technology according to design of the present utility model Test available technical scheme, all should fall in protection domain of the present utility model.
