Technical Field

[0001] This invention relates to the field of injection molding machine technology, specifically to a working method of an automated feeding device. Background Technology

[0002] A toothbrush is a cleaning product with a handle. It is used to apply toothpaste to the brush and then repeatedly brush all parts of the teeth to maintain oral hygiene. Existing toothbrushes are all plastic products, which are injection molded during the manufacturing process. When the injection molding machine is in use, it needs an external feeding device to continuously supply injection molding raw materials.

[0003] Existing feeding equipment for toothbrush injection molding machines has the following drawbacks: 1. The feeding pipe is prone to blockage, requiring constant maintenance, which wastes time and reduces processing efficiency; 2. Different parts of a toothbrush require different raw materials, and the feeding equipment cannot change the material box, making it inconvenient to use.

[0004] Therefore, those skilled in the art provide a method for operating an automated feeding device to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide a method for operating an automated feeding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automated feeding device operating method includes the following steps: An external power supply is connected to an electromagnetic coil. The electromagnetic coil, installed inside the material cylinder, is activated via a control panel on the worktable. The electromagnetic coil heats a metal heat-conducting plate on the inner wall of the cylinder, a partition metal plate inside the cylinder, and a feeding pipe passing through the cylinder. After preheating to the set temperature, a feeding cover corresponding to the partition metal plate on the cylinder is opened, and plastic granules are fed into the cylinder for melting and heating. Depending on the type of raw material, a solenoid valve installed on the feeding pipe is opened, opening the feed port on the feeding pipe at the location corresponding to the activated solenoid valve. An embedded suction pump at the bottom of the feeding pipe then feeds the material. A vacuum is created by suction within the pipeline. Molten raw materials enter the discharge pipeline through the open feed port. When the solenoid valve is closed, the raw materials do not enter the discharge pipeline. The raw materials that do enter are drawn down by the air pressure of the pressure blower installed at the top of the discharge pipeline and the negative pressure of the embedded suction pump. The raw materials enter the spiral feeding pipe along the discharge pipe set around the embedded suction pump. The spiral feeding pipe transports the raw materials to the output end and squeezes them into the sealing sleeve installed in the turntable at the output end of the spiral feeding pipe. The raw materials are then discharged from the metal discharge pipe corresponding to the sealing sleeve on one side, thus achieving material supply. The rotary motor connected to the turntable can drive the turntable to rotate, allowing different sealing sleeves to be connected to the output end of the spiral feeding pipe.

[0007] As a further embodiment of the present invention: a barrel cover is provided at the top of the barrel, and a pressure blower is provided in the middle of the top of the barrel cover.

[0008] As a further embodiment of the present invention: the barrel lid is hinged to the material cylinder, the pressure blower is a blower, the pressure blower passes through the barrel lid and communicates with the inside of the feeding pipe, and the feeding pipe is made of metal and has a hollow structure inside.

[0009] As a further embodiment of the present invention: the separating metal plate is a conical structure welded to the inner wall of the material cylinder, the feeding pipe passes through the separating metal plate, the feeding hole is formed through the feeding pipe, at least one feeding hole is provided at the position where the feeding pipe connects to the separating metal plate, and the solenoid valve is nested on the feeding pipe.

[0010] As a further embodiment of the present invention: the discharge pipe passes through the workbench and is fixed, the discharge pipe wraps around and fixes the embedded suction pump, the embedded suction pump is connected to the discharge pipe, and the spiral feeding pipe is sealed and welded to the discharge pipe.

[0011] As a further embodiment of the present invention: a spiral roller is rotatably connected inside the spiral feeding tube, and a discharge motor is installed on the outside of the spiral roller. The spiral feeding tube is fixedly installed to the bottom of the workbench by a welded support rod, and the turntable can rotate relative to the spiral feeding tube. The discharge motor drives the spiral roller to rotate and transport the raw material to the output end of the spiral feeding tube.

[0012] As a further embodiment of the present invention: two or more sealing sleeves are distributed circumferentially in the turntable, and the sealing sleeves are sealed and clamped to the discharge pipe, wherein the discharge pipe is a metal pipe.

[0013] As a further embodiment of the present invention: the top of the rotary motor is fixedly installed with the spiral feeding tube, the output end of the rotary motor is fixedly installed with the turntable through the motor hole, and a feeding soft rubber tube is nested outside the discharge tube.

[0014] As a further aspect of the present invention: an electromagnetic vibration coil is nested on the outer wall of the discharge pipe, and the electromagnetic vibration coil generates electromagnetic vibration to accelerate the output of raw materials in the discharge pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by setting a feeding pipe on the traditional injection molding machine feeding equipment and installing an embedded suction pump in the feeding pipe, the molten material in the barrel can be efficiently sucked out and transported, avoiding blockage in the pipe, ensuring the normal and continuous operation of the equipment, and improving processing efficiency.

[0026] 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 is connected to 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 is a conical structure 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 18 passes through it. The material is formed on the feeding pipe 10, and each partition metal plate has at least one feed hole 18 at the connection between the feeding pipe 10 and the partition metal plate. The solenoid valve 11 is nested on the feeding pipe 10. The discharge pipe 6 passes through the workbench 2 and is fixed. 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.

[0027] The spiral feed tube 7 is internally connected to a spiral roller 23, and an external discharge motor 8 is installed on 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 discharge tube 13 is externally nested with a feeding soft rubber tube 19, which is connected to the injection end of the injection molding machine.

[0028] 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, which forms 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, which accelerates 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.

[0029] The working method of an automated feeding device is as follows: When the device is in use, it is connected to an external power source. The electromagnetic coil 4 is activated through the control panel 3 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 into 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 feeding pipe but also... 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.
