Problems solved by technology

However, the current mixing methods and methods usually use synchronous or interval injection of new materials and recycled materials into the hopper. In actual use, it is usually difficult to selectively use recycled materials. It is only equivalent to using recycled materials as an additive. The main component of the mix is ​​still virgin

Embodiment Construction

[0020] In order to make it easy to understand the technical means, creative features, achieved goals and effects of the present invention, the following embodiments will describe the present invention in detail with reference to the accompanying drawings.

[0021] see figure 1 and figure 2 As shown in , in the operation method of the mixing feeding hopper provided in this embodiment, the mixing feeding hopper includes a hopper body 1, and at least one material level gauge 2 is installed on the inner wall of the hopper body 1, and the material level gauge 2 defines the interior of the hopper body 1 The upper end of the hopper body 1 has a new material inlet and a return material inlet, and a new material conveying line 4 is installed in the new material inlet, and a first control valve 6 is installed on the path of the new material conveying line 4. A return conveying line 5 is installed in the material inlet, and a second control valve 7 is installed on the path of the retur...

Abstract

The invention discloses an operation method of a mixed feeding hopper. Firstly, the return material of m time is input, and then the steps of input return and replenishment are performed according to the detection result of the material level gauge or the delay is waited for n time. During the process of inputting new material The material level height is detected in real time by the material level gauge again to ensure that the amount of new material input does not exceed the full material line. Its technical solution enables the priority to use the return material during operation, automatically executes the feeding action, ensures the height of the material level in the hopper, avoids material shortage and material blockage caused by excessive material level, and realizes unmanned and time-delayed operation. The k time length can ensure the accuracy of the level gauge detection and eliminate interference signals.

Description

technical field [0001] The invention relates to the technical field of feeder equipment on an injection molding machine, in particular to a method for operating a mixing feeding hopper. Background technique [0002] With the promotion of environmental protection awareness and policies, the plastic recycling market has gradually matured. Among them, the most important way is to crush the recycled block plastic into PP or PE particles by a crusher as a return material, and mix it with new materials to form The mixed material is injected into the feed port of the injection molding machine for use. In addition, the return material also includes the remaining pellets after injection molding of a product, and the mixing operation as described above is generally adopted. However, the current mixing methods and methods usually use synchronous or interval injection of new materials and recycled materials into the hopper. It is usually difficult to selectively use the recycled materi...
