Communication method between injection molding machine and feeding system

Abstract

The present invention discloses a communication method of an injection molding machine and a feeding system. A feeding system is provided with a microprocessor and an injection molding machine; the injection molding machine is provided with PLCs; the microprocessor is configured to receive information emitted by the injection molding machine and control the operation of the feeding system; the microprocessor is connected with the injection molding machine through a RS485 interface; and the microprocessor and the PLCs establish communication connection through an MODBUS protocol in a RTU mode.The RS485 is long in transmission distance and high in anti-jamming capability and has a multi-station capacity, the feeding system can be connected with a plurality of injection molding machines through an interface to form a network, and has a verification function in the transmission process so that it is does not need to worry the data error in the transmission process; and after the technology is employed, users can accurately complete replacement of raw materials without errors, and compared to a current manual notification of a feeding house, the transmission of the raw materials is completed with more rapidness, more safety and more accuracy.

Description

technical field [0001] The invention relates to the field of injection molding machines, in particular to a communication method between an injection molding machine and a material supply system. Background technique [0002] Injection molding machine is to make thermoplastics or thermosetting materials into plastic products of various shapes. The production process of plastic products is as follows: feed the raw materials into the barrel, and after the raw materials are dried, they are sent to the injection molding machine for melting and plasticization, and high pressure is applied to the molten plastic to make it inject and fill the mold cavity. [0003] At present, the plastic toy injection molding process of domestic and foreign enterprises is not highly automated, consumes energy, has serious cross-infection of raw materials, and the recycling of raw materials is not thorough. The vast majority of toys in the world are produced in China. About 90% of China's toy produ...

Problems solved by technology

In this mode of centralized material supply, the injection molding workshop and the material room are separated, and the raw materials are delivered to the corresponding injection molding machine through the material supply system; what raw materials the injection molding machine needs, notify the material supply room, and then the material supply room will deliver the corresponding raw materials to Corresponding to the injection molding machine, there are many human links and uncertain factors; for example, the injection molding workshop and the material supply room have not communicated with the injection molding machine that needs to be loaded or the required raw materials, then the raw materials will not reach the required injection molding machine, or The raw materials provided to the injection molding machine are not correct, which will seriously affect the production and even damage the screw of the injection molding machine
