The invention relates to the field of plastic processing and manufacturing, in particular to an automatic feeding device for plastic particles and liquid color master of a plastic processing machine.
Background
Coloring preparations can be divided into three main categories: toner, color masterbatch and liquid color masterbatch. The color powder and the color master batch are both solid, and the liquid color master batch is a liquid flowable mixture, also commonly known as color oil and color paste, and is formed by mixing one or more of pigments, and/or dyes, and/or functional additives with a liquid carrier. The amount of the toner and the color master batch is more, and the liquid color master batch is a novel product, and compared with the color master batch, the liquid color master batch has the advantages of less amount, good dispersion effect, uniform coloring, quick color change and the like, so that the amount of the liquid color master batch is continuously increased, and the application range is also continuously enlarged.
At present, in the plastic production process, the toner has the problems of low automation degree and time and labor consumption. The masterbatch can add equipment automatic interpolation with look female, but this equipment is comparatively complicated and expensive, and the operation is inconvenient, and to liquid look female, because of the liquid can be glutinous in original hopper of weighing, can't fall into completely and mix the hopper, so ordinary weighing and metering mode is not suitable for. The adding mode of the plastic particles is mainly manual adding, and although the patent CN205438938/CN205185149/CN205889597/CN206690374 discloses an automatic plastic particle batching and mixing device, the design is more suitable for automatic feeding and mixing of powdery raw materials or color master batches and plastic particles and is not suitable for automatic feeding and mixing of liquid color master batches and plastic particles; in addition, plastic particles are mainly weighed in the above patent, the weighing and metering mode is high in manufacturing cost, the metering accuracy is greatly influenced by the weighing component, more accurate metering is obtained, and the requirement on the weighing component is higher.
The plastic products can produce water gap materials, leftover materials or defective products in the production process, the colors of the materials are consistent with those of qualified products, and the materials can be recycled and added into original production equipment for recycling. The recovery device of patent 201420408677.4 retrieves the mixture of plastic raw material and toner that is not formed, and the toner separates with the plastic raw material, carries out the reutilization to both respectively again, and both separation degree can influence subsequent colouration, easily causes the coloured inhomogeneous, and this kind of colouring method utilizes the toner to colour, easily causes dust pollution, and degree of automation is low, consumes time and consumes labour. The recycling system described in patent 201510444837.X is for the case that the colorant is toner or color masterbatch, and is not suitable for liquid color masterbatch, because the patent uses an electronic scale for metering, and the liquid color masterbatch is very easy to adhere to the electronic scale due to a viscous liquid, so that the color masterbatch cannot be completely poured, the weighing stability is poor, and a rear conveying pipeline is polluted. The recycling system of patent 201510571120.1 does not relate to the problem of colouring plastics, but only mentions recycling of waste material, whereas if toner is used for colouring, the means of absorbing small particles of dust in the apparatus will inevitably suck off part of the toner, which affects the colouring of the plastics.
