Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] The embodiment of the present invention discloses a hydraulically driven extruder. The present invention improves the traditional process by using a motor to drive a hydraulic motor, and the hydraulic motor drives a hydraulic reducer. The hydraulic reducer transmits force to the distribution box, and the distribution box drives the screw to complete the process. Plasticized, the output product is not only small in size, light in weight and high in energy...

Abstract

The invention discloses a hydraulic drive extruder which comprises a motor, a shaft extension portion, a coupler, a hydraulic pump, a hydraulic speed reducer, a distribution box, an extruder body and a control device. The shaft extension portion stretches out of the outer side of the motor, the coupler is installed on one side of the shaft extension portion, the hydraulic pump is connected with the shaft extension portion through the coupler, the hydraulic speed reducer is connected with the hydraulic pump through a main oil drainage pipe, a main oil return pipe, a pressure limiting valve oil return pipe and a shell oil relief pipe which correspond to an oil inlet, an oil outlet, an inner return oil relief port and a shell oil relief port in sequence, one end of the hydraulic speed reducer is provided with a transmission shaft, the distribution box is connected with the hydraulic speed reducer through the transmission shaft, the distribution box is connected with the extruder body through a flange, and the control device is connected with the motor, the hydraulic pump, the hydraulic speed reducer and the extruder body through wires. The motor, the hydraulic pump and the hydraulic speed reducer are fixedly installed on the base, and a screw rod is arranged inside the extruder body. The hydraulic drive extruder is small in size, low in weight, high in energy rate, clear in structure, clear in layout, easy to operate and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of extruders, in particular to a hydraulically driven extruder. Background technique [0002] Existing extruders, such as twin-screw extruders, rely on the pressure and shear force generated by the rotation of the screws to fully plasticize and mix the materials, and then extrude the products through dies and molds. The twin-screw extruders on the market use a traditional high-power motor to drive the reduction box, then drive the distribution box, and then the distribution box drives the screw to perform plasticization and molding. This method generally uses a high-power motor, which has high power consumption, high noise, large volume, inconvenient maintenance, high failure rate, small force conversion, and large loss. [0003] Therefore, how to provide a hydraulically driven extruder with low power consumption is an urgent problem to be solved by those skilled in the art. Contents of the invention [...
