Cutting wire tensity and temperature measurement and control device for EPS (Expanded Poly Styrol) slab cutting machine

Abstract

The invention provides a cutting wire tensity and temperature measurement and control device for an EPS (Expanded Poly Styrol) slab cutting machine, belonging to the field of machining. The cutting wire tensity and temperature measurement and control device is used in non-manual installation regulation and temperature control of cutting wires for solving the problems of large installation error and human injury due to broken wires. The cutting wire tensity and temperature measurement and control device for the EPS slab cutting machine is composed of a cutting wire set tension automatic maintaining and adjusting mechanical traction mechanism, a cutting wire tension sensor, a cutting wire temperature sensor, a control traction mechanism and a cutting wire working temperature control circuit. The cutting wire set tension automatic maintaining and adjusting mechanical traction mechanism is composed of a step motor, a supporting plate, a lead screw, a movable disk, an optical axis and a wire hanging plate; and the tension sensor comprises a step motor, a lead screw, a movable disk, an optical axis, a pressure sensor, an F contactor and a PT100 temperature sensor installed at one side of a cutting wire of the traction mechanism. The invention has the advantages of automatically maintaining the cutting wire tension and the cutting wire working temperature and adjusting errors to maintain the cutting wire at the optimal working state, improving the cutting quality of EPS slabs and eliminating potential safety hazards caused by manual installation.

Description

technical field [0001] The invention belongs to the field of processing machinery, in particular to an automatic adjustment device for tension and temperature of an electric heating cutting wire in an EPS benzene board cutting machine. technical background [0002] Building energy saving is one of the major issues of environmental protection and energy saving today. The production technology of EPS insulation materials is also particularly important. The cutting technology of EPS often adopts electrothermal cutting technology. At present, the tension of the cutting wire of the cutting machine is completely adjusted manually by experience. When the cutting wire is installed too loosely, the cut plate will have a radian; when the installation is too tight, it is easy to break the wire when it encounters a corner, which will greatly reduce the working efficiency and product qualification rate of the cutting machine. In addition, when the cutting wire is installed manually, it ...

AI Technical Summary

Problems solved by technology

When the cutting wire is installed too loosely, the cut plate will have a radian; when the installation is too tight, it is easy to break the wire when encountering a corner, which will greatly reduce the working efficiency and product qualification rate of the cutting machine

In addition, when the cutting wire is installed manually, it is easy to cause broken wires and cause workers to be injured.

There is a serious threat to the production safety of the enterprise

[0003] In addition, in the existing plate cutting machine, all the cutting wires are powered in parallel by the power supply and given by a fixed current, and the cutting wires will accumulate heat in the EPS material during operation, resulting in excessive local temperature, causing the cutting plate to exist at the corner. Overcut problem affects cutting accuracy
