Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, the present invention is a temperature control system suitable for industrial-grade 3D printers, which is a PID-based temperature control system, including a thermometer, an AD conversion module, a programmable logic controller PLC, a PID control module, and a solid-state relay .

[0018] The thermometer placed at the mouth of the forming chamber of the industrial 3D printer is used to obtain the real-time temperature in the forming chamber.

[0019] The thermometer is connected with the AD conversion module, and the thermometer transmits the temperature analog quantity collected to the AD conversion module.

[0020] The AD conversion module is connected with the programmable logic controller PLC, and the AD conversion module converts the analog temperature value transmitted by the thermometer into a digital value, and tran...

Abstract

The invention discloses a temperature control system suitable for an industrial 3D printer, belonging to the technical field of the 3D printer. The temperature control system can quickly reach the setting temperature of the industrial 3D printer and stabilize as well as maintain the temperature in a forming cabin. The temperature control system comprises a thermodetector, an AD conversion module, a PLC (Programmable Logic Controller), a PID control module and a solid relay. The situations of unstable temperature control, ultra-long preheating time or failure in reaching the setting temperature of the present 3D printing equipment and even the situation of influencing the quality of the printed workpiece can be avoided, the temperature control system is suitable for metallic and nonmetallic industrial 3D printers and the instantaneity and the stability of the temperature system can be promoted.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and relates to temperature control for industrial-grade 3D printing equipment, in particular to a control system that can quickly reach the set temperature of industrial-grade 3D printing equipment and stably maintain the temperature in a molding chamber. Background technique [0002] Industrial-grade 3D printers need to be equipped with a heating system according to the process requirements. The function of the heating system mainly reflects the following two aspects: one is to ensure that the printing raw materials quickly reach the temperature value required by the process; the other is to ensure that the temperature in the molding cylinder is kept at a certain level. within range. The control of the temperature system directly affects the quality of the printed workpiece, so the temperature control plays a vital role in the work of the system. [0003] The current 3D printing equipment h...
