[0030] Injection molding raw material mixers that incorporate antibacterial materials, such as Figs. 1-3As shown, the device includes a mixing drum 10 for processing injection molding raw materials. A hollow base 20 is installed at the bottom of the mixing drum 10. The top of the mixing drum 10 has an open structure with a top cover 30 installed at the opening. A hollow stirring shaft 40 is coaxially installed inside the mixing drum 10. An antibacterial coating 11 is provided on the inner wall of the mixing drum 10 and the bottom surface of the top cover 30. A servo stirring motor 21 is coaxially installed at the center of the base 20, and the rotating shaft 22 of the servo stirring motor 21 passes through the mixing drum. The bottom of the mixing drum 10 extends into the interior of the mixing drum 10; a pump 31 for conveying cleaning fluid or water is installed at the center of the top of the top cover 30, a hollow area 35 is opened at the center of the interior of the top cover 30, and a sealed bearing 34 is embedded at the center of the bottom surface of the top cover 30; a square-section plug-in connector 43 is coaxially connected to the bottom of the stirring shaft 40 and is inserted into the rotating shaft 22, and a connecting pipe head 44 that is adapted to the inner ring size of the sealed bearing 34 and is inserted into the top of the stirring shaft 40. The connecting pipe 44 is connected to the interior of the hollow area 35. Several uniformly spaced antibacterial rinsing holes 42 are provided on the outer wall of the stirring shaft 40. The mixing drum 10 is used to process injection molding raw materials. Antibacterial coatings 11 are provided on the inner wall and the bottom surface of the top cover 30 to effectively improve the antibacterial properties of the raw materials. At the same time, a servo stirring motor 21 is provided in the base 20 installed at the bottom of the mixing drum 10. Its rotating shaft 22 passes through the bottom of the mixing drum 10 and is connected to the plug 43 at the bottom of the stirring shaft 40 to achieve efficient stirring of the injection molding raw materials. In addition, the infusion pump 31 installed on the top of the top cover 30 can be connected to the hollow area 35 and the interior of the stirring shaft 40 through the connecting pipe 44 to deliver cleaning liquid or water into the stirring shaft 40. The water is then sprayed out evenly from the antibacterial rinsing holes 42 on the outer wall to clean the stirring shaft 40 and the inner wall of the mixing drum 10, effectively preventing raw material residue and bacterial growth, so that the injection molding raw material mixer has a better cleaning and antibacterial effect.

[0031] It is worth noting that the antibacterial coating 11 has a thickness of 0.25-0.5mm, which effectively prevents bacterial contamination of the injection molding raw material during processing and improves the hygienic quality of the raw material.

[0032] Furthermore, a discharge pipe 12 with a control valve is installed at the bottom of the outer wall of the mixing drum 10, which allows the injection molding material to be discharged conveniently after processing, thereby improving production efficiency and ease of operation.

[0033] The connector 43 and the rotating shaft 22 are locked together by radial fixing bolts to ensure the stability and reliability of the stirring shaft 40 during the stirring process and to avoid poor stirring effect or equipment damage due to loosening.

[0034] Specifically, the inlet end of the infusion pump 31 is equipped with an inlet pipe 33, and the outlet end of the infusion pump 31 is connected to the interior of the hollow area 35, so that the cleaning liquid or water can smoothly enter the interior of the stirring shaft 40 and be sprayed out through the antibacterial flushing hole 42 to achieve effective cleaning of the equipment.

[0035] In addition, the top surface of the top cover 30 is symmetrically provided with lifting rings 32 with a U-shaped cross section on both sides, which makes it easier for the operator to apply force when opening or closing the top cover 30, thereby improving the comfort and safety of operation.

[0036] It is worth noting that each antibacterial rinsing hole 42 is equipped with a check valve that allows only liquid to flow out, ensuring that the cleaning liquid or water can only flow out in one direction, avoiding contamination or equipment damage caused by liquid backflow, and further improving the cleaning effect and hygiene quality of the equipment.

[0037] The working principle of this injection molding raw material mixer that incorporates antibacterial materials:

[0038] First, the injection molding material is added into the mixing drum 10 in an appropriate manner, and then the top cover 30 is closed;

[0039] Next, the servo stirring motor 21 is started, and its rotating shaft 22 will drive the stirring shaft 40 to rotate inside the mixing drum 10 to efficiently stir the injection molding raw materials. During the stirring process, the speed of the servo stirring motor 21 can be adjusted as needed to achieve the best stirring effect.

[0040] After mixing is complete, turn off the servo mixing motor 21; at this time, the processed injection molding raw material can be discharged from the mixing drum 10 by opening the control valve on the discharge pipe 12.

[0041] After each use, in order to keep the equipment clean and hygienic, the infusion pump 31 and servo motor 21 need to be started. The infusion pump 31 draws in cleaning liquid or water through the inlet pipe 33 and delivers it to the hollow area 35 and the interior of the stirring shaft 40. Then, the cleaning liquid or water will be evenly sprayed out from the antibacterial rinsing hole 42 on the outer wall of the stirring shaft 40 to clean the stirring shaft 40 and the inner wall of the mixing drum 10. Since each antibacterial rinsing hole 42 is equipped with a check valve that can only discharge liquid, it can be ensured that the cleaning liquid or water will not flow back into the infusion pump 31, avoiding the risk of contamination or equipment damage.

[0042] Finally, turn off the infusion pump 31 and wait for the equipment to air dry or wipe it clean with a clean cloth.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
