Description

Technical Field

[0001] The invention relates to the field of plastic pellet recovery devices, in particular to a plastic pellet processing waste recovery device. Background Art

[0002] Plastic granules are a type of plastic material. Common types include general-purpose plastics, engineering plastics, special plastics, etc. Plastics are widely used and are indispensable components in home appliances, automobiles, mobile phones, PCs, medical devices, and lighting appliances. In the process of making products, plastic granules will produce a lot of waste materials. These waste materials can no longer be used to make products and need to be recycled and then made into a shape that is easy to store before continuing to be made.

[0003] The existing plastic pellet recycling device has the following problems during operation:

[0004] 1. Before recycling plastic pellets, they need to be cleaned. The dust on the plastic pellets will affect the molding and appearance during the subsequent liquefaction. Whether it is spraying or cleaning in a pool, the cleaning effect is relatively poor and the cleaning efficiency is also relatively low;

[0005] 2. After the plastic pellets are melted and formed, they need to be cooled. However, the cooling mechanism needs to be turned on and circulated for some time, which cannot be synchronized with the mold opening time, and the speed cannot be adjusted according to the different stages of mold opening, resulting in poor cooling effect and low cooling efficiency.

[0006] 3. After the plastic pellets are melted and formed, the product needs to be ejected. At this time, the ejection mechanism does not cooperate well with the mold opening timing, resulting in poor ejection effect. Summary of the invention

[0020] The present invention has the following beneficial effects:

[0021] 1. When the residual material is put into the feed hopper, the present invention introduces cleaning water from the water inlet pipe into the feed hopper, mixes with the residual material for cleaning, and cooperates with the spiral blades in the spiral conveyor to clean the residual material. The spiral blades can rotate and impact together with the water flow and the residual material to improve the cleaning effect, and can clean while transporting, thereby improving the cleaning effect.

[0022] 2. The present invention allows the cleaning water to enter the circulation pipe and then enter the two cooling pipes, first cooling the fixed mold, and then spraying it out through the output pipe and the nozzle to cool the product below. The cleaning water can be recycled and reused, so that the cleaning water can be used for cooling, thereby improving the utilization rate of cooling water.

[0023] 3. In the present invention, when the cleaning water enters the circulation pipe, the cleaning water will also enter the ejection pipe. The cleaning water will move the movable piece, drive the ejector to move, and eject the product. After that, the cleaning water in the ejection pipe will be discharged, and the telescopic rod and the reset spring will drive the movable piece to reset, so that the product can be slowly ejected during the mold opening process, thereby improving the ejection effect.

[0024] 4. The present invention uses a movable sheet driven by cleaning water. At this time, the ejection speed of the ejector is linked to the cooling speed, so that the ejection timing and the cooling time can be coordinated.

[0025] 5. The present invention rotates the cleaning blade and passes through the slope button during rotation. The slope button is pressed in by the cleaning blade, and the slope button drives the shielding plate to open the output port, wherein a part of the activated carbon between the two blades is output from the output port. Then the cleaning blade continues to rotate and opens the input port by the same principle. The activated carbon in the input port enters between the two blades, and the cycle is repeated, so that the activated carbon is easy to replace and the adsorption effect is improved.

[0026] 6. In the process of the power motor driving the first ball screw to rotate, the present invention drives the second ball screw to rotate through the second pulley system, so that the moving block moves on the second ball screw, slowly drives the fan to move for cooling, and can cooperate with the cleaning water sprayed from the nozzle to cool and improve the cooling effect.

[0027] 7. In the process of mold closing, the power motor drives the first ball screw to rotate, and the second ball screw is driven to rotate through the second pulley system, so that the movable block moves on the second ball screw, and slowly drives the fan to move toward the fixed mold, so that the fan can blow away the debris on the fixed mold. The fan activity process is coordinated with the mold opening and closing process to complete different tasks, which not only improves the coordination of various components, but also improves the coordination between the cooling stage and the cleaning stage and the mold opening and closing.

[0028] 8. In the present invention, when the fixed mold and the movable mold are closed, the adjusting block and the fixed block cooperate to seal the water storage pipe. During the mold opening process, the power motor drives the first ball screw to rotate, and the first ball screw drives the rotating tube on the water storage pipe to rotate through the third pulley system, thereby driving the adjusting block to rotate, so that the adjusting block and the fixed block are staggered, so that the cleaning water can enter the circulation pipe, and the mold opening and closing processes can control the cooling process and be synchronized with the mold opening time. The speed is adjusted according to different stages of mold opening to improve the cooling effect and the cooling efficiency.

[0029] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
