Description

Technical Field

[0001] This utility model belongs to the field of ABS recycled material die casting technology, and in particular relates to a feeding and mixing device for ABS recycled material die casting. Background Technology

[0002] Before die casting, ABS recycled materials need to be recycled, impurities (such as metals, other plastics, labels, etc.) removed, crushed, granulated and dried. Die casting involves injecting molten material into a mold through an extruder or other equipment and holding it under pressure and cooling for a period of time.

[0003] If plastics are recycled multiple times, the molecular chains may break, reducing their impact resistance and heat resistance. Therefore, 20-30% virgin material needs to be added before die casting, along with reinforcing agents and stabilizers. Since the amount of reinforcing agents and stabilizers added is small and easy to add, while the amount of virgin material added is larger and needs to be mixed with recycled material.

[0004] If recycled materials and virgin materials are directly fed into the extruder hopper separately, uneven mixing will occur. If a mixing device is set up before the extruder feed, the existing mixing device will have uneven mixing (differences in density and particle size can easily lead to stratification), degradation risk (multiple mixing or high-speed stirring may exacerbate the thermal and oxidative degradation of recycled materials and reduce melt strength), and low efficiency (manual feeding is not conducive to precise control and is labor-intensive, the mechanical mixing of the mixing blades is difficult to meet the needs of continuous production, and batch consistency is poor). Summary of the Invention

[0005] The purpose of this invention is to provide a feeding and mixing device for die casting of recycled ABS material. The device prepares the recycled material and the new material in the recycled material cylinder and the new material cylinder before feeding. The ratio of the two materials can be controlled by the weighing sensor. During feeding, the material in the recycled material cylinder and the new material cylinder is completely discharged, which controls the precise ratio of the single feeding amount and avoids repeated mixing. At the same time, the mixing cylinder design mixes the materials during the feeding process, which improves the mixing uniformity and reduces the risk of degradation caused by mechanical stirring. It also eliminates the need for repeated manual feeding, thus improving efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a feeding and mixing device for die casting of recycled ABS material, including a recycled material cylinder, a new material cylinder and a mixing material cylinder;

[0008] The bottom end of the recycled material cylinder is provided with an inner feed pipe;

[0009] The new material cylinder is concentrically sleeved on the circumference of the recycled material cylinder. The bottom end of the new material cylinder is provided with an eccentric part. The bottom end of the eccentric part is connected to an outer feed pipe. Both the inner feed pipe and the outer feed pipe are provided with switch valves. The diameter of the outer feed pipe is one-third of the diameter of the inner feed pipe.

[0010] The mixing cylinder has open top and bottom, and is concentrically positioned directly below the recycling cylinder without interfering with it. The bottom end of the inner feed pipe extends into the upper part of the mixing cylinder.

[0011] A central shaft is provided at the center of the mixing cylinder. A spiral plate is fixed between the central shaft and the mixing cylinder to form a spiral channel. An external pipe that communicates with the spiral channel is fixed on the circumferential side of the mixing cylinder. The end of the external pipe is connected to the external feed pipe through a flexible hose.

[0012] A vibration motor is fixed to the periphery of the mixing cylinder, and several lower support plates are fixed to the periphery of the mixing cylinder. Several upper support plates are fixed to the periphery of the bottom end of the recycling cylinder, and springs are fixed between the upper support plates and the lower support plates.

[0013] Furthermore, it also includes an outer frame, with several outer support plates fixed to the periphery of the new material cylinder, the outer frame being disposed below the several outer support plates, and weighing sensors being provided between the several outer support plates and the outer frame.

[0014] Furthermore, it also includes an extrusion device, which is equipped with a feed hopper, and the mixing cylinder is concentrically positioned directly above the feed hopper. The outer frame is fixed to the extrusion device by a bracket.

[0015] Furthermore, it also includes a control device, which includes a processor and several control units. The switching valves, weighing sensors, and vibration motors of the inner and outer feed pipes are all electrically connected to the processor.

[0016] Furthermore, the top of the recycled material cylinder is provided with a conical hopper, and the top peripheral side of the new material cylinder is connected to a receiving hopper through an inclined tube.

[0017] Furthermore, the outer pipe is inclinedly disposed on the outside of the mixing cylinder, and a reinforcing plate is fixed between the outer pipe and the mixing cylinder.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model prepares recycled and new materials before feeding by using recycled material cylinders and new material cylinders. The ratio of the two can be controlled by a weighing sensor. During feeding, the materials in the recycled material cylinder and new material cylinder are completely discharged, which controls the precise ratio of the single feeding amount and avoids repeated mixing. At the same time, the mixing cylinder design mixes the materials during the feeding process, which improves the mixing uniformity and reduces the risk of degradation caused by mechanical stirring. It also eliminates the need for repeated manual feeding, thus improving efficiency.

[0020] 2. This utility model can be installed on an extruder through an outer frame. Its small size saves space and the corresponding internal material volume is small. During the pressure holding and cooling period of the die casting process, it can be fully prepared before material feeding without affecting the normal operation of the die casting process and meeting the needs of continuous production.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
