Feeding device for molding bag shell

Abstract

The invention relates to a feeding device for molding a bag shell. The feeding device comprises a material mixing bin, a swivel nut, a screw, a driving mechanism, a material adding hopper, a filter screen plate and an air drying mechanism, wherein the swivel nut, the screw, the driving mechanism, the material adding hopper, the filter screen plate and the air drying mechanism are arranged inside the material mixing bin in the vertical direction; and the material adding hopper is inserted in from the side portion of the material mixing bin and communicated with the swivel nut, the filter screen plate is located at the bottom of the material adding hopper and used for filtering materials with the grain diameter larger than the design size, and the air drying mechanism is communicated with the side wall of the material mixing bin and used for conducting air drying on the scattered materials. The upper end of the screw is exposed out of the upper end of the swivel nut and is screwed out from the top of the material mixing bin, and a cavity is formed by the inner wall and the top of the material mixing bin and the periphery of the swivel nut; and a material discharging pipe for discharging the materials is arranged on the material mixing bin. According to the feeding device, the multiple materials are stirred and conveyed firstly through the screw and then are further mixed in a freely-scattering manner, so that the materials are evenly mixed sufficiently; and meanwhile, damping and blocking of the materials can be prevented, the quality of the bag shell is guaranteed, the scrapping number is decreased, and cost is saved.

Description

technical field [0001] The invention relates to luggage forming equipment, in particular to a material feeding device for forming a luggage shell. Background technique [0002] The molding steps of the luggage shell mainly include: 1) Measuring and mixing ABS plastic, toughening agent, base color material and other materials in equal parts; 2) After mixing, heat-melt them into the screw extruder; The extruder is discharged into the extruder to form a multi-layer sheet; 4), the sheet is cut according to size, and then put into the forming mold for heat melting, forging and pressing, and finally cooling and forming. [0003] However, in step 1), once the material is mixed unevenly, the case body cannot pass the strength or toughness test, and the case body after production is scrapped, which not only increases the production cost, but also wastes a lot of materials . [0004] At the same time, when the raw materials are placed for a long time, if they get wet, they are easy ...

Problems solved by technology

[0003]However, in step 1), once the material is mixed unevenly, the shell of the luggage cannot pass the strength or toughness test, resulting in the production of the luggage. The shell is scrapped, which not only increases the production cost, but also wastes a lot of materials

[0004]At the same time, when the raw materials are placed for a long time, if they are damp, they are easy to stick to the inner wall of the mixing bin, causing the phenomenon of material clogging, which brings great harm to the feeding work. great inconvenience
