In the plastic injection molding process, the plastic parts used for injection molding are usually mixed and molded by a variety of different plastic particles. In order to ensure that the injection molded plastic parts can achieve the expected physical and chemical properties, each must be strictly controlled according to the production process. The weight ratio of the plastic particles of different components. Therefore, the plastic particles should be weighed before mixing. Because traditional methods mostly use manual weighing, manual weighing will cause various errors, and the weight ratio of each component does not meet the production process. Therefore, it is necessary to solve the above-mentioned problems.

The volume of the filter is 2-5mm.

A weight sensor is arranged under the filter screen, and the weight sensor is connected to a first comparison controller through a wire, and the first comparison controller is connected to a motor through a wire.

The weighing device includes a gravity sensor arranged under the baffle, a second comparison controller arranged on the cylinder, the gravity sensor and the second comparison controller are connected through a wire, and the second comparison controller is connected with the second comparison controller through a wire. Cylinder connection.

The bottom ends of both ends of the baffle are arranged on the top of the mixer.

The mixer is preset with a fixing device, and the air cylinder is arranged on the fixing device.

The cylinder is connected with an electromagnetic valve, and the movement of the cylinder is controlled by the electromagnetic valve.

The front end of the stirring blade is provided with an arc.

The basic principle of the utility model:

In this application, the color masterbatch material is poured into the feed inlet. First, the finer color masterbatch material is selected through the filter to pass through to the weighing device. In the initial state, the cylinder drives the baffle to seal at the bottom end of the load-bearing device. When the weight in the middle becomes heavier and heavier, the gravity sensor set under the baffle transmits the collected weight to the second comparison controller. When the weight information exceeds the value set by the second comparison controller, the second comparison controller controls The cylinder works, and the cylinder drives the baffle to draw out, which is convenient for the color masterbatch material to enter the mixer. The mixing blade of the mixer in this application can be used to clean the inner wall of the mixer by brushes. The spray nozzle on the shower pipe regularly cleans the mixer; in this application, because the large-particle color masterbatch raw material stays on the filter screen, the continuous pour of the color masterbatch raw material is converted, and the accumulation of color masterbatch particles in the filter screen is increasing. The more, the weight sensor transmits the collected weight to the first comparison controller. When the weight information exceeds the value set by the first comparison controller, the first comparison controller controls the operation of the motor, and the motor rotates the shaft to filter the tilt After completion, the first comparison controller automatically controls the operation of the motor, so that the filter screen is stuck in the feeding device.

The beneficial effects of the utility model:

The overall structure of the utility model is simple, and a filtering and draining mechanism is added. Only the finer masterbatch material can pass through, so that the clumped masterbatch material can be smoothly discharged from the outlet pipe. The above method can effectively remove the large amount of the masterbatch material. Granules improve the uniformity of the mixture and balance the nutrition of the granules after processing into granules; in addition, the setting of the weighing device can accurately control the amount of each color master material. It is convenient for later cleaning and must be convenient for use.
