Adjustable feeding equipment for polyamide particles and masterbatches

Abstract

The present invention provides an adjustable feeding device for polyamide particles and masterbatches. The adjustable feeding device for polyamide particles and masterbatches comprises a first metal box, a first vacuum pump fixedly connected to the interior of the first metal box, a third metal box fixedly connected to the lower surface of the first metal box, and a second metal box fixedly connected to the right surface of the first metal box. By designing a weighing device, when the polyamide particles are moved, the magnetism of an adjustable electromagnet can be converted into a weight parameter, achieving accurate measurement and avoiding the influence of particle diameter. By designing a second motor with adjustable height, masterbatches of different diameters can be moved, avoiding the inability to effectively control the transmission weight due to the influence of the masterbatch diameter when directly transmitted through an auger. Pre-mixing is performed during the transmission process, thereby increasing the effectiveness of the device.

Description

Technical Field

[0001] The invention relates to the technical field of feeding equipment, in particular to an adjustable feeding equipment for polyamide particles and masterbatches. Background Art

[0002] Polyamide granules and masterbatches are commonly used in plastics processing. Polyamide granules are a plastic raw material primarily used to manufacture heat-resistant and corrosion-resistant parts and appliances, such as automotive hoods, pipes, and valves. Masterbatches are materials that evenly disperse pigments within plastic granules, enhancing the color and appearance of plastic products. Adjustable feeders are devices used to control the supply and delivery of materials, adjusting the feed rate and speed according to production needs. In plastics processing, adjustable feeders are commonly used to feed polyamide granules and masterbatches into extruders or injection molding machines for the manufacture of plastic products. The feeding of polyamide granules and masterbatches typically requires different equipment and methods. Polyamide granules typically require vacuum feeding to ensure precise feed rates and speeds, while masterbatches typically require screw feeding to ensure uniform pigment dispersion within the plastic granules.
