Description

The invention relates to the processing of polymer materials into products and can be used in rotary conveyor plants for the manufacture of rubber technical products.

The purpose of the invention is to expand the technological capabilities of the rotor by ensuring its use in rotary installations for pressing polymer products of various designs and by allowing the material to be loaded in the form of preformed blanks,

In Fig.1 schematically shows the proposed rotor, the cut; FIG. 2 is a section A-A in FIG. on fig.Z - section bb in figure 2.

The mold loading rotor contains a vertical drive shaft 2, mounted in a stationary cup 2, mounted on the shaft 1 with the possibility of turning in a horizontal plane a disk

3 with slots 4 for placing the blanks; a feeder 5 for feeding the blanks into the slots 4; and means 6 for opening the molds. The rotary disk 3 is rigidly connected with an asterisk 7 having a gear coupling 8 attached to the middle part of the shaft 1. The rotary disk 3 is mounted centrally to the drive shaft 1 and is equipped with a curved guide 9 enveloping its outer surface in the area from the feeder 5 to the zone feed blanks and molds. The slots 4 for placing the blanks are made in the form of shaped grooves on the side surface, having a height H equal to 1.5 of the height h of the blank, and a disk 3, the width a equal to twice the diameter d of the blank.

The rotor has a means for supplying blanks from the sockets 4 into the mold, having an ejector and a control cam 10. The ejector is made in the form of pushers 11 with springs 12 radially mounted on the disk 3 in accordance with the number of sockets

4 and having rollers 13 on the ends facing the discs. The pushers 11 are mounted with the possibility of axial movement. The control cam 10 is disk-mounted and fixedly mounted on a rack 14, concentric to the shaft 1, with the possibility of interaction with the rollers 13 of the pushers 11.

The cup 2 and the post 14 are fixed on the bed 15. The shaft 1 is rotated through a gear wheel 16. The tool 6 for opening the molds is made in the form of a copier 17 mounted on the cup 2 and fixed on the upper end of the shaft 1 of the drum 18 with the circumference of his sliders 19, having at the lower ends of the clamps 20.

The rotor operates as follows. A description of the operation of the rotor is given in relation to its use as part of the rotor-conveyor line, on the transport

chains 21 of which are installed molds 22 with plungers 23. Shaft 1 is driven into rotation, the drum 18, the disk 3 and the sprocket 7, which interact with the chain 21, rotate with it. At the same time, the sliders 19. interact with the cam 17, lower their grips 20 interact with the plunger 23 of the mold 22 located in the loading zone. The mold opens. By rotating the disk 3 of the workpiece 24

the polymer material, in particular rubber, is fed into the slots 4 by the feeder 5 and moved by it along the guide 9 to the mold loading area. In this case, the pushers 11, rolling rollers

13, through an unobtrusive cam 10, push the workpiece 24 out of the socket 4 into the mold 22. The ram 19 rams the plunger 23 into the mold 22 and the gripper 5 disengages from it.

The synchronous reciprocating movement of the sliders 19 is ensured by the geometry of the copier 17. Then the cycle repeats.
