[0002] An injection molding machine is a device used to manufacture plastic products. It injects molten plastic material into a mold and obtains the desired plastic product after cooling and solidification. The feeding mechanism of the injection molding machine is prone to blockage during use, which may bring a series of problems and inconveniences to the production process. It is easy to cause production interruption: The blockage of the feeding mechanism will cause the injection molding machine to stop and interrupt the production process. This will lead to a waste of time and resources, affecting the execution of the production plan and the delivery time of the product. It is easy to cause a waste of resources: When the feeding mechanism is blocked, it may be necessary to stop production, clean up the blockage, repair the equipment, etc., which will cause a waste of time, manpower and materials. And it will cause a decrease in production efficiency: Blockage will lead to a decrease in production efficiency, prolong the production cycle, and reduce the output of production.
