Extrusion mechanism of rubber flat plate machine

By designing lifting holes and sliding groove structures in the extrusion mechanism of the rubber flatbed machine, and combining them with the use of knob screws and internal hex bolts, the problems of unstable nut positioning and inconvenient spring disassembly and assembly are solved. This enables stable adjustment of the limit plate and convenient replacement of the spring, improving the reliability and ease of maintenance of the equipment.

AI Technical Summary

Technical Problem

In the extrusion mechanism of existing rubber flatbed machines, the nut lacks axial positioning after adjustment, resulting in poor stability of the limit plate height adjustment and inconvenient disassembly and assembly of the spring.

Method used

By opening a lifting hole and a side wall groove at the bottom of the lifting extrusion block, the knob screw drives the lifting plate to move and tightens the internal hex bolt for axial positioning. Combined with the threaded connection of the positioning rod embedded in the groove at the bottom of the rubber plate receiving seat, the positioning rod and the receiving seat are fixed with a nut, so as to achieve stable installation and convenient disassembly of the spring.

Benefits of technology

It improves the stability of the limit plate height adjustment and the ease of spring disassembly and assembly, reduces the possibility of knob screw loosening, and improves the reliability and maintenance efficiency of the equipment.

Abstract

The utility model discloses an extrusion mechanism of a rubber flat plate machine, which belongs to the technical field of rubber flat plate machines and comprises a rubber plate accommodating seat and a lifting extrusion block arranged above the rubber plate accommodating seat, and a plurality of positioning rods are detachably mounted at the top end of the rubber plate accommodating seat. The bottom end of the positioning rod is sleeved with a spring, the top end of the positioning rod is slidably sleeved with a lifting baffle abutting against the spring, protruding parts are symmetrically fixed to the side wall of the lifting extrusion block, and a rotary knob screw inserted into the lifting baffle in a threaded mode is rotationally clamped between the two protruding parts. And the inner hexagon bolt drives the moving block to be tightly connected with the side wall of the knob screw, so that the knob screw keeps axial positioning, the situation that the knob screw is loosened is greatly reduced, and the stability of the lifting plate after height adjustment is improved.
