Novel maintenance-free screw post-disassembly type direct-drive extrusion device and operation method thereof

Abstract

The invention discloses a novel maintenance-free screw post-disassembly type direct-drive extrusion device which comprises an extrusion device machine head (1), an extrusion screw (2), a machine barrel (3), a feeding component (4) and a hollow direct-drive torque motor (5); and the hollow direct-drive torque motor (5) comprises a motor body (51), a motor shaft (52), an extrusion screw adapter (53) and a motor driver. According to the novel maintenance-free screw post-disassembly type direct-driven extrusion device, the extrusion screw (2) is connected with the motor shaft (52) through the extrusion screw adapter (53), so that the extrusion screws (2) with different characteristics can be quickly replaced under the condition that the original mechanical structure and heating and cooling equipment are not disassembled; and rapid switching and process adjustment of products with different process parameters and different materials are realized. The maintenance-free screw post-disassembly type direct-drive extrusion device can support an enterprise to establish a flexible product production line so as to meet the market competition requirements of environmental protection, high efficiency, energy conservation and environmental friendliness.

Description

technical field [0001] The patent of the present invention belongs to the field of extrusion device design, and in particular relates to a novel maintenance-free screw rear disassembly type direct-drive extrusion device and an operation method thereof. Background technique [0002] With the diversification of market demand for products processed by extrusion equipment, customers have put forward requirements for continuous research and development of new products for manufacturers using extrusion equipment. The traditional extrusion device production line mainly adopts the connection method of servo motor, high-density compact reducer and extruder. The production line mainly has the following problems: [0003] Every time the traditional extrusion device changes the product line and replaces the extrusion screw, the head part of the extrusion device needs to be removed first, and then the head of the extrusion device is moved forward as a whole to reserve space for the screw...

AI Technical Summary

Problems solved by technology

[0003] Every time the traditional extrusion device changes the product line or replaces the extrusion screw, it is necessary to remove the head part of the extrusion device first, and then move the head of the extrusion device forward as a whole to reserve a space for the screw to be pulled out. Pulling out the extrusion screw from the front end of the reduction box as a whole is not only time-consuming and labor-intensive, but also requires a lot of space in the factory. Every time the screw is replaced due to product replacement, it is like an overhaul of the production line, and a lot of waste is generated. Oil, waste liquid, waste gas and other by-products that pollute the environment

In addition, what is more troublesome is that after the replacement, the production line needs to be debugged and calibrated again, and the production process parameters need to be re-adjusted to meet the demand.

That is to say, the existing extrusion production line has certain advantages in meeting the large-volume demand for a single raw material. High maintenance costs, slow R&D and verification of new products and high costs

[0004] In addition, the use of the existing extrusion production line must be equipped with a reducer, and the noise generated by the reducer is very loud, which has an adverse impact on the surrounding environment. Workers working in such a noisy environment for a long time will cause many occupational diseases. The energy consumption of the reducer is also quite large. Today, with the protection of the environment and the rational use of resources and energy as the main body, the reducer is not in line with the development of the times, especially the waste of resources in the structure of the extruder is quite large.
