[0002] In the injection molding process for producing large plastic spools, the design and function of the feeding device for injection molding parts are crucial. It is mainly responsible for accurately conveying raw materials from the storage bin to the hopper of the injection molding machine to ensure the continuity and stability of the production process. An efficient feeding device can avoid material waste and ensure the uniform distribution of plastic raw materials. Common feeding devices include screw conveyors, vibrating conveyors, and pneumatic conveyors. These devices not only improve work efficiency but also reduce manual intervention and improve the level of automation.

[0003] Traditional feeding devices mainly include screw feeders and vacuum feeders. Screw feeders push materials by rotating a screw shaft in a barrel. However, this device is prone to clogging in the barrel if the raw material has slightly high moisture content or slight agglomeration. Existing injection molding part feeding devices solve the clogging problem of screw feeders by adding vibration devices and stirring mechanisms. However, during the unloading process, due to the structural characteristics of the screw blades and the viscosity of the material, some material remains in the screw blades and barrel and cannot be completely discharged.

The support frame 1 serves as the supporting frame for the entire device, providing a stable mounting foundation for other components, ensuring that each component maintains its relative position during operation, bearing the overall weight of the device and various forces generated during material transmission and processing, ensuring that the equipment can work smoothly and continuously. A U-shaped block 3 is fixedly connected to the left side of the outer wall of the support frame 1. The U-shaped block 3 provides a key support point and rotation track for the rotational connection of the feeding pipe 5, allowing the feeding pipe 5 to rotate flexibly within its limited range. A flange 8 is fixedly connected to the bottom of the conical feed block 6. Flange 8, as a commonly used connecting component, can conveniently and quickly connect the conical feed block 6 to the feed pipe 7, ensuring that no leakage occurs during material transmission and guaranteeing the sealing and stability of material conveying. The bottom of flange 8 is fixedly connected to the feed pipe 7, which is the initial channel for material to enter the device. It guides the material from the external source to flow smoothly into the feed pipe 5. The bottom of feed pipe 7 is connected to feed pipe 5, which is the main component for material lifting and conveying. Fixing rings 4 are fixedly connected to the left and right sides of the outer wall of feed pipe 5. Fixing rings 4 not only enhance the structural strength of feed pipe 5 but also prevent it from being damaged by the impact of material and its own weight during long-term operation. The U-shaped block 3 deforms due to the volume of material transported, providing a stable point of contact for the feeding pipe 5 to connect with other components. The inner wall of the U-shaped block 3 is rotatably connected to the left fixed ring 4. A servo motor 9 is fixedly connected to the right side of the feeding pipe 5. The servo motor 9 serves as a power source, driving the auger 11 to rotate stably. The output end of the servo motor 9 passes through the feeding pipe 5 and is fixedly connected to the auger 11. The auger 11 is a key component for material transport within the feeding pipe 5. Its spiral blade structure can push the material forward along the axial direction of the feeding pipe 5 during rotation. The right side of the outer wall of the feeding pipe 5 is connected to the discharge pipe 10, which serves as the material output port, allowing the feeding pipe 5 to change within a certain range. The tilt angle can be adjusted to adapt to the material receiving and conveying needs at different heights and positions. A filter plate 12 is fixedly connected to the top of the inner wall of the conical feed block 6. A partition plate 14 is rotatably connected to the bottom of the filter plate 12. A heating tube 13 is fixedly connected to the top of the filter plate 12. An electric telescopic rod 15 is rotatably connected to the inner wall of the support 1. The telescopic movement of the electric telescopic rod 15 can precisely control the rotation angle of the feed pipe 5, realize the flexible adjustment of the material conveying path, and improve the versatility and adaptability of the equipment. One end of the electric telescopic rod 15 is rotatably connected to the right fixed ring 4. A cleaning and drying mechanism 2 is set on the top rear side of the support 1. The cleaning and drying mechanism 2 is used to clean and dry the pipe.

[0032] Reference Figure 1 , Figure 3 and Figure 4The cleaning and drying mechanism 2 includes a water storage tank 201, which serves as a storage container for cleaning water. The water storage tank 201 is fixedly connected to the top rear side of the support 1. A water pump 202 is fixedly connected to the left side of the outer wall of the water storage tank 201. The water pump 202 is the power source for conveying the cleaning water, capable of drawing water from the water storage tank 201 and pressurizing it to provide sufficient pressure to deliver it to the annular pipe 206 through the hose 203. By controlling the power and speed of the water pump 202, the flow rate and pressure of the cleaning water can be adjusted to meet the cleaning needs of different degrees of dirt. The top of the water pump 202 is connected to the hose 203, which serves as a flexible pipe connecting the water pump 202 and the annular pipe 206, enabling flexible transmission of cleaning water between different components of the equipment. The left side of the hose 203 passes through the conical feed block 6 and is connected to the annular pipe 206. The annular pipe 206 is installed on the conical feed block 6. Inside block 6, its annular structure allows the cleaning water to be evenly distributed around the inner wall of the conical feed block 6. Multiple connected spray heads 207 spray the water out in a radial pattern, achieving all-round cleaning of the inside of the conical feed block 6, ensuring that every corner and surface is cleaned. Multiple spray heads 207 are connected to the outer wall of the annular pipe 206. The spray heads 207 serve as the final cleaning execution components. A drying fan 204 is fixedly connected to the bottom of the bracket 1. The drying fan 204 is a device that provides hot air. It draws in outside air and heats it through an internal heating element to generate high-temperature hot air, which is used to dry the cleaned pipe. An air pipe 205 is connected to the left side of the drying fan 204. The air pipe 205 serves as a hot air delivery channel, delivering the high-temperature hot air generated by the drying fan 204 to the feeding pipe 5. The left side of the air pipe 205 is connected to the left side of the feeding pipe 5.

[0033] Reference Figure 1 , Figure 2 and Figure 3An observation window 16 is provided on the front side of the outer wall of the conical feed block 6. The observation window 16 allows the operator to directly observe the feeding status of the material inside the conical feed block 6. An outer frame 17 is fixedly connected to the outer wall of the observation window 16. The outer frame 17 not only protects the observation window 16 from damage caused by external impact, but also provides a handle 18 fixedly connected to the front side of the outer wall of the bracket 1. The handle 18 provides the operator with a convenient point of force application, facilitating push and pull operations when moving the equipment. A sponge sleeve 19 is fixedly connected to the outer wall of the handle 18, which can increase the operator's grip. The friction between the part and the handle 18 prevents the equipment from losing control due to slippage when holding the handle 18. The four corners at the bottom of the bracket 1 are rotatably connected to the movable wheels 20. The movable wheels 20 enable the entire equipment to move freely on relatively flat ground, making it convenient to transfer the equipment between different work areas. The outer wall of the movable wheels 20 is rotatably connected to the brake pedal 21. The brake pedal 21 is used to control the rotation of the movable wheels 20. When the equipment moves to the designated position, pressing the brake pedal 21 can stop the movable wheels 20 from rotating and fix the equipment in the current position.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A nameplate 22 is fixedly connected to the top left side of the bracket 1. The nameplate 22 records the model of the equipment in detail. A warning sign block 23 is fixedly connected to the top right side of the bracket 1. The warning sign block 23 is used to remind operators of safety precautions when working around the equipment. A water level trough 24 is opened on the front side of the outer wall of the water storage tank 201. The water level trough 24 can intuitively display the water level in the water storage tank 201. A sealing plate 25 is fixedly connected to the outer wall of the water level trough 24. The sealing plate 25 mainly serves to protect the water level trough 24. A column 26 is fixedly connected to the top front side of the bracket 1. An alarm light 27 is fixedly connected to the top of the column 26. The alarm light 27 can promptly emit a clear warning signal, allowing operators or people around to quickly discover and take appropriate measures.

[0035] Working principle: First, push the device to the required feeding position. Then, by starting the electric telescopic rod 15, drive the feeding pipe 5 to rotate above the U-shaped block 3, thereby determining the height of the feeding pipe 10 and the required feeding position. Then, pour the required raw material into the conical feeding block 6. By starting the heating tube 13, dry the moisture in the raw material. Then, rotate the partition 14. At this time, the raw material will pass through the filter plate 12 and enter the feeding pipe 7. Then, by starting the servo motor 9, drive the auger 11 to rotate, pushing the raw material from the feeding pipe 7 to the top and entering the feeding position from the discharge pipe 10. This reduces the problem of the raw material sticking to the top of the auger 11 during transportation due to the moisture content in the raw material.

[0036] The cleaning liquid is added to the water storage tank 201 through the cleaning and drying mechanism 2. After the loading is completed, the cleaning liquid is extracted by starting the water pump 202 and introduced into the hose 203, then into the interior of the annular pipe 206. Finally, it is sprayed on the inner wall of the conical feed block 6 through the spray head 207. The impurities washed off enter the feeding pipe 5 through the feed pipe 7. Driven by the servo motor 9, the auger 11 rotates to extract the mixture containing impurities and discharge it through the discharge pipe 10. After the mixture is discharged, the drying fan 204 is started to blow air in. The air then enters the bottom of the feeding pipe 5 through the air pipe 205 and blows air into the interior to dry the moisture, thus quickly drying the interior for the next use.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
