The screw ejection device is provided with a machine body support, the upper end of the machine body support is provided with a machine barrel, the upper end and the lower end of an opening in the left side of the machine barrel are each provided with an oil cylinder, the end of a telescopic rod of each oil cylinder is connected with a lock head through a hinged shaft, the right side of the machine barrel is sequentially and fixedly provided with a feeding box and a connecting box, the right side of the connecting box is connected with a gearbox, a screw is mounted in the machine barrel, the right end of the screw is located in the feeding box, a feeding opening is formed in the upper end of the feeding box, a tail gear is additionally installed at the right end of the screw, the right end of the tail gear makes contact with the left end of a polish rod, the right end of the polish rod rightwards extends into the gearbox from the interior of the machine barrel, the polish rod in the gearbox is sleeved with a gear fixing hollow shaft, a gear is fixedly installed on the outer side of the gear fixing hollow shaft, a jack is mounted on the right side of the gearbox, a jack piston rod of the jack extends leftwards into the gearbox to be in contact with the right end of the polish rod, and the jack is connected with a hydraulic pump through a high-pressure oil pipe.

Description

technical field [0001] The invention relates to the field of tire manufacturing, in particular to a rubber extruder screw ejector device. Background technique [0002] As we all know, rubber extruder equipment is the main equipment and key equipment in the tire industry. Single screw extruder, double compound extruder unit, triple compound extruder or more compound extruder units play an important role . The screw extrudes the rubber in the barrel of the extruder or rotates empty. The screw top and the inner wall of the barrel are prone to fatigue and wear. The gap needs to be measured regularly. If it exceeds the process requirements, it needs to be replaced in time. However, when the screw needs to be ejected when replacing the screw, due to the tight connection between the gear at the end of the screw and the gear sleeve connected to the power output shaft of the extruder reducer, or the corrosion of the surface of the gear sleeve, the force is too large, resulting in th...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies in the prior art, the present invention provides a rubber extruder screw ejector device to solve the problem that the screw of the original screw ejector is under small force and the screw is rotated manually, causing the screw to not rotate or the screw to be screwed. The phenomenon of deformation and bending causes the problem that it cannot be disassembled normally and reduces the service life of the equipment
