Description

Technical Field

[0001] The utility model relates to the technical field of extrusion devices, in particular to a mixing extrusion device. Background Art

[0002] The mixing extruder is a mechanical device used to heat and melt the raw materials and then extrude them into the desired shape through mechanical pressure. It is widely used in the plastics, rubber, food, medicine, chemical and other industries to produce various pipes, films, plates, profiles, puffed foods, candies, biscuits, syringes, infusion tubes and other products. The main components of the mixing extruder include a feeding device, a screw, a barrel, a die head, etc. The pressure and shear force generated by the rotation of the screw allow the materials to be fully plasticized and evenly mixed, and then formed through the die. At present, a mixing extruder is also required in the preparation process of polylactic acid composite materials.

[0003] The existing mixing extrusion device is provided with a diverter plate and a filter screen in the transition zone between the die and the screw head, and its function is to change the material flow from spiral motion to linear motion, prevent unmelted particles from entering the die, filter out impurities such as metal, and ensure the quality of the extruded polylactic acid composite material. However, no metal impurity removal structure is provided in the barrel. The metal impurities enter the extruder along with the raw materials, which easily cause wear to the extrusion screw and the barrel, and affect the service life of the extrusion screw and the barrel. Therefore, a mixing extrusion device is proposed. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 4 As shown, it relates to a mixing extrusion device, including an extruder body 1, a feeding component is fixedly penetrated at the feed end of the extruder body 1, a sorting shell 4 is fixedly penetrated at the top of the feeding component, the feeding component includes a feeding barrel 2, and the feeding barrel 2 is fixedly penetrated between the feeding end of the extruder body 1 and the sorting shell 4, and an auger 13 is rotatably connected to the inner wall of one side of the feeding barrel 2. After the auger 13 rotates, it cooperates with the feeding barrel 2 to transport the raw materials in the sorting shell 4 to the extruder body 1.

[0023] A barrel 6 is fixedly passed through the top of the sorting shell 4 , a bracket 5 is fixedly installed on one side of the outer surface of the barrel 6 , and the bracket 5 is fixedly connected to the extruder body 1 , the bracket 5 supports the barrel 6 , and is beneficial to the installation of the barrel 6 .

[0024] The inner walls on both sides of the sorting shell 4 are rotatably connected with a rotating shaft 11, and the outer surface of the rotating shaft 11 is symmetrically fixedly connected with two side plates 9, and a plurality of magnetic plates are fixedly connected between the two side plates 9, and the magnetic plates are fixedly connected to the rotating shaft 11, and the plurality of magnetic plates include a fixed plate 10, and the fixed plate 10 is fixedly connected to the side plate 9 and the rotating shaft 11, and an electromagnet 12 is fixedly installed inside the fixed plate 10, and the fixed plate 10, the side plate 9 and the rotating shaft 11 can cooperate to form a plurality of material troughs, which is convenient for the electromagnet 12 to adsorb metal impurities in the raw material.

[0025] A transmission assembly is installed between the rotating shaft 11 and the feeding assembly, and the transmission assembly includes a shell 8, and the shell 8 is fixedly connected to the sorting shell 4. Two pulleys 14 are symmetrically rotatably connected to the inner wall of one side of the shell 8, and the mounting shafts of the two pulleys 14 penetrate the shell 8 and are fixedly connected to the adjacent rotating shaft 11 and the adjacent auger 13. A belt body 15 is commonly sleeved between the two pulleys 14. A motor 7 is fixedly installed on one side of the outer surface of the shell 8, and the driving shaft of the motor 7 penetrates the shell 8 and is fixedly connected between the adjacent pulleys 14. The motor 7 drives the pulley 14 to rotate, and the pulley 14 can drive another pulley 14 to rotate through the belt body 15, thereby synchronously driving the rotating shaft 11 and the auger 13 to rotate.

[0026] A waste discharge pipe 3 is fixedly passed through one side of the outer surface of the sorting shell 4. The arrangement of the waste discharge pipe 3 is conducive to the discharge of adsorbed metal impurities.

[0027] Working principle: first, add the raw material into the barrel 6, then the motor 7 starts to run, the motor 7 drives the pulley 14 to rotate, the pulley 14 drives another pulley 14 to rotate through the belt body 15, so that the rotating shaft 11 and the auger 13 can be driven to rotate synchronously, and the rotating shaft 11 drives the side plate 9 and the fixed plate 10 to rotate. When the raw material enters the sorting shell 4 through the barrel 6, it will fall between two adjacent fixed plates 10, and then rotate with the rotation of the rotating shaft 11. When one of the fixed plates 10 is in a tilted state, the raw material begins to fall under the action of gravity. During this period, the electromagnet 12 has been adsorbing metal impurities. When the fixed plate 10 adsorbed with metal impurities moves to the waste pipe 3, the electromagnet 12 in the fixed plate 10 at this point stops running. Due to lack of adsorption force, the metal impurities are discharged through the waste pipe 3 under the action of gravity. When the fixed plate 10 is away from the waste pipe 3, the electromagnet 12 runs again, and the raw material falling into the bottom of the sorting shell 4 enters the feeding barrel 2 at the same time, and then is transported to the extruder body 1 through the auger 13.
