Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-5In this embodiment of the invention, an automated feeding device includes a workbench 2, a material cylinder 1 is provided at the top center of the workbench 2, a barrel cover 24 is provided at the top of the material cylinder 1, a pressure blower 25 is provided at the top center of the barrel cover 24, a feeding pipe 10 is provided at the bottom of the pressure blower 25, a separating metal plate 9 is provided on the feeding pipe 10, a feeding hole 18 is provided on the outer wall of the feeding pipe 10, a solenoid valve 11 is provided at the feeding hole 18, an embedded suction pump 21 is provided at the bottom of the feeding pipe 10, a discharge pipe 6 is provided around the embedded suction pump 21, a spiral feeding pipe 7 is provided at the bottom of the discharge pipe 6, a turntable 12 is provided at the output end of the spiral feeding pipe 7, two or more sealing sleeves 15 are arranged in a circle in the turntable 12, a discharge pipe 13 is inserted into the sealing sleeve 15, and a rotary motor 22 is provided in the middle of the turntable 12.

[0027] Example 1: The barrel lid 24 is hinged to the material cylinder 1. The pressure blower 25 is a blower that passes through the barrel lid 24 and communicates with the inside of the feeding pipe 10. When the feeding pipe 10 is blocked, the pressure blower 25 can provide downward air pressure to force the raw material out of the pipe, reducing maintenance work and realizing automatic feeding. The feeding pipe 10 is made of metal and has a hollow internal structure. The feeding pipe 10 is heated synchronously with the heating component to prevent the internal raw material from solidifying. The separating metal plate 9 has a conical structure and is welded to the inner wall of the material cylinder 1. The feeding pipe 10 passes through the separating metal plate 9, and the feed hole 1... 8 is formed through the feeding pipe 10, and at least one feed hole 18 is provided at the connection between each partition metal plate and the feeding pipe 10. The solenoid valve 11 is nested on the feeding pipe 10. The discharge pipe 6 is fixed through the workbench 2. After the solenoid valve 11 is opened, the feed hole 18 is exposed, and molten raw material can enter. The discharge pipe 6 wraps and fixes the embedded suction pump 21. The embedded suction pump 21 is connected to the feeding pipe 10. The spiral feeding pipe 7 is sealed and welded to the discharge pipe 6. The embedded suction pump 21 can draw the raw material around the feeding pipe 10 into the pipe through the action of negative pressure suction.

[0028] Example 2: A spiral roller 23 is rotatably connected inside the spiral feed tube 7. A discharge motor 8 is installed on the outside of the spiral roller 23. The discharge motor 8 is a servo motor that can intelligently control the speed. The spiral roller 23 can squeeze the molten raw material into the sealing sleeve 15, thereby pressing it into the discharge tube 13 and conveying it to the outside under a certain pressure. The spiral feed tube 7 is fixedly installed to the bottom of the worktable 2 by a welded support rod 17. The turntable 12 is rotatably connected to the rotary motor 22. The sealing sleeve 15 is embedded in the turntable 12 and is sealed and clamped to the discharge tube 13. The discharge tube 13 is a metal tube. The top of the rotary motor 22 is fixedly installed to the spiral feed tube 7. The output end of the rotary motor 22 is fixedly installed to the turntable 12 through the motor hole 16. The motor hole 16 can facilitate the fixing and disassembly of the rotary motor 22. A feeding soft rubber tube 19 is nested outside the discharge tube 13 and is connected to the injection end of the injection molding machine.

[0029] Example 3: A metal heat-conducting plate 5 is formed on one side of the inner wall of the material cylinder 1. An electromagnetic coil 4 is fixed on one side of the inner wall of the metal heat-conducting plate 5. The electromagnetic coil 4 generates a changing magnetic field, forming eddy currents in the metal heat-conducting plate 5 for heating. The electromagnetic coil 4 is connected to a control panel 3. The control panel 3 can control the heating temperature and the intelligent operation of other electrical equipment on the device. The control panel 3 is fixed on the workbench 2. An electromagnetic vibration coil 20 is nested on the outer wall of the discharge pipe 6. The electromagnetic vibrator uses the principle of the movement of a conductor in a magnetic field to achieve high-speed vibration of the discharge pipe 6, accelerating the discharge of the internal raw materials. A feeding cover 14 is fastened to the outer wall of the material cylinder 1 at the corresponding position of the dividing metal plate 9. The feeding cover 14 is used to feed plastic granule raw materials.

[0030] A method of using an automated feeding device: When using this device, an external power source is connected. The control panel 3 activates the electromagnetic coil 4 to heat the metal heat-conducting plate 5, the separating metal plate 9, and the feeding pipe 10. After preheating to a certain temperature, the feeding cover 14 is opened, and plastic granules are fed into the material cylinder 1 for melting and heating. During feeding, depending on the type of material, the electromagnetic valve 11 at the contact position between the feeding pipe 10 and the separating metal plate 9 is opened. The embedded suction pump 21 draws suction from the feeding pipe 10, creating a vacuum negative pressure. The molten material enters the feeding pipe 10 through the electromagnetic valve 11 and the feed hole 18. When the electromagnetic valve 11 is not open, the material not only enters... The raw material entering through the discharge pipe 10 is sucked down and enters the spiral feeding pipe 7 along the discharge pipe 6. The electromagnetic vibration coil 20 uses the principle of electromagnetic vibration to accelerate the release of the raw material inside the pipe and avoid blockage. The discharge motor 8 drives the spiral roller 23 to rotate, squeezing the raw material into the sealing sleeve 15 and discharging it from the metal discharge pipe 13 connected to the sealing sleeve 15 on one side. The material is then fed into the toothbrush injection molding machine through the feeding soft rubber tube 19 for injection molding. When it is necessary to adjust the type of raw material, different solenoid valves 11 are opened, and the motor drives the turntable 12 to rotate, adjusting the sealing sleeves 15 at other positions to connect with the spiral feeding pipe 7 to achieve the output of different raw materials. This equipment is designed to efficiently extract molten material from the barrel 1 for transport, preventing blockages in the pipes, ensuring continuous and normal operation of the equipment, and improving processing efficiency. It can separately heat and melt different raw materials, which is beneficial for the equipment to simultaneously supply different raw materials for injection molding, improving the utilization efficiency of the material supply equipment. It can also achieve adjustable output of different raw materials, which is beneficial for flexibly selecting different raw materials for different parts during toothbrush injection molding, thereby improving the injection molding efficiency of toothbrushes.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
