The first support frame 4 is fixed on the feeding door 14 by a second bolt 16.
The square bearing 9 with the pin is hinged with the second support frame 11 and the pressing block 5, and the pressing block 5 is fixed on the second support frame 11 by a first bolt 15; a baffle ring 7 is arranged at the left end of the square bearing 9 with the pin, and the baffle ring 7 is fixed on the screw rod 2 by a set screw 8; the right end of the square bearing 9 with the pin is provided with a baffle disc 10, the baffle disc 10 is fixed on the right end face of the screw rod 2 by a first bolt 15, and the combined action of the baffle ring 7 and the baffle disc 10 is to axially position the right end journal of the screw rod 2.
The second support bracket 11 is fixedly connected with the feeding machine barrel 12 through a second bolt 16.
The feeder barrel 12 is hinged to a feeder gate 14 by a pin 13.
2 left ends of lead screw install spanner 1, the left end of lead screw 2 has square or hexagon section to stretch out, spanner 1 be equipped with square or interior hexagonal hole and with the square or hexagon section of 2 left ends of lead screw stretch out the cooperation, with spanner 1 axial fixity through the shoulder of nut 6 and 2 left ends of lead screw, realize that spanner 1 rotates and drives lead screw 2 and rotate.
The utility model has the advantages that: the utility model discloses simple structure realizes the horizontal switching of rubber extruder feeding door easily to can make the laborsaving light of switching of rubber extruder feeding door.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a plan view showing an opened state of the feed door.
In the figure: 1 spanner, 2 lead screws, 3 square nuts with pins, 4 first support frames, 5 pressing blocks, 6 nuts, 7 retaining rings, 8 set screws, 9 square bearings with pins, 10 retaining discs, 11 second support frames, 12 feeding machine barrels, 13 pins, 14 feeding doors, 15 first bolts and 16 second bolts.
Detailed Description
