[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example: Figure 1-3 As shown, this utility model provides an automatic batching and metering device for polylactic acid injection filler, including a mixing cylinder 2 and a support plate 1. A support plate 3 is fixedly mounted on the upper surface of the support plate 1, and a storage bin 31 is fixedly mounted on the upper surface of the support plate 3. There are four storage bins 31, which are evenly spaced. A feeding pipe 36 is provided on the upper surface of the storage bin 31, and a transmission pipe 37 is connected to the lower surface of the storage bin 31. The lower end of the transmission pipe 37 is connected to the mixing cylinder 2. A control plate 4 is fixedly mounted on the upper surface of the support plate 1. The upper surface of the control plate 4 (Siemens S7-1200 PLC) is provided with an operation panel 41 (Weintek MT8071iE touch screen) and a solenoid valve 42 (SMC VX210). The control board 4 integrates complex and precise circuits and control chips, possessing powerful data processing and command transmission capabilities. It can receive various command information input from the operation panel 41, such as the proportion parameters of different materials and the total quantity setting for each batch. The operation panel 41 is the key interface for operators to interact with the entire device, featuring a user-friendly design with a clear and intuitive display area and convenient operation buttons. The solenoid valve 42, installed on the corresponding transmission pipe 37, is a crucial actuator for achieving precise automatic batching and metering control. The solenoid valve 42 operates based on electromagnetic induction; when the electrical signal sent by the control board 4 is transmitted to the solenoid valve 42, it generates electromagnetic force, thereby driving the valve to open and close. By cooperating with the control board 4 and the solenoid valve 42, the amount of each material can be precisely controlled, realizing automatic batching and metering, avoiding errors that may occur with manual batching, and improving the quality stability of polylactic acid injection filler. The solenoid valve 42 is set on the corresponding transmission pipe 37. The operation panel 41 on the control board 4 can be used to set the batching parameters, such as the amount of each material. The control board 4 controls the opening and closing of the solenoid valve 42 according to the set parameters. When batching is required, the control board 4 issues a command to open the corresponding solenoid valve 42, and the material in the storage tank 31 will flow into the mixing cylinder 2 through the transmission pipe 37. Since the solenoid valve 42 on the transmission pipe 37 can accurately control the flow rate and discharge time of the material, accurate metering of various materials can be achieved.
[0020] The operator inputs the proportions of different materials and the total amount to be dispensed each time via the control panel 41. This information is transmitted to the control board 4 via the communication interface. After receiving the instructions from the control panel 41, the control board 4 processes and analyzes the data according to the preset program and logic. Then, the control board 4 sends an electrical signal to the solenoid valve 42 installed on the transmission pipe 37. When the solenoid valve 42 receives the electrical signal from the control board 4, it generates electromagnetic force based on the principle of electromagnetic induction, driving the valve to open. Different materials flow from the storage tank 31 into the mixing cylinder 2 through the transmission pipe 37. The control board 4 precisely controls the opening time and degree of the solenoid valve 42 according to the preset material dosage to achieve precise control of the flow rate of each material. When the set material dosage is reached, the control board 4 sends a closing signal to the solenoid valve 42. The solenoid valve 42 generates a reverse electromagnetic force, driving the valve to close and stopping the delivery of that material. This cycle continues until all materials are dispensed according to the set proportions, thus realizing the automatic dispensing and metering process.
[0021] The mixing cylinder 2 is located below one side of the support plate 1. Several through slots 38 for use with the transmission pipe 37 are formed on the upper surface of the mixing cylinder 2. A rotating column 22 is rotatably mounted inside the mixing cylinder 2. One end of the rotating column 22 passes through the mixing cylinder 2 and is fixedly connected to a reinforcing disc 25. A second motor 21 is mounted on one side of the mixing cylinder 2. A protective plate 24 is fixedly mounted on one side of the mixing cylinder 2, and the upper surface of the protective plate 24 is fixedly connected to the second motor 21. The output end of the second motor 21 passes through the mixing cylinder 2 and is fixedly connected to the rotating column 22. Several stirring elements 23 are fixedly sleeved on the outer surface of the rotating column 22. The stirring elements 23 are arranged in an equal... The mixing cylinder 2 is located below the support plate 1. The transmission pipe 37 transports the material into the mixing cylinder 2 through the through groove 38. The second motor 21 starts, and its output end drives the rotating column 22 to rotate. Several stirring pieces 23 fixedly sleeved on the rotating column 22 rotate with the rotating column 22 to fully stir the various materials entering the mixing cylinder 2, so that the different materials are evenly mixed to form a polylactic acid injection filler that meets the requirements. The mixed polylactic acid injection filler is discharged through the discharge pipe 26 connected to one side of the mixing cylinder 2, and can be used for subsequent packaging and other processes.
[0022] A first motor 33 is fixedly mounted on the upper surface of the storage tank 31, and the output end of the first motor 33 passes through the storage tank 31 and is fixedly connected to a rotating shaft 32. Several stirring columns 34 are fixedly mounted on the outer surface of the rotating shaft 32, and telescopic rods distributed in a ring are fixedly mounted on the outer surface of the rotating shaft 32. A filter screen 35 is fixedly connected to the outer end of the telescopic rods. The mesh size of the filter screen 35 is carefully designed to effectively filter out impurities, lumps, or particles that do not meet the size requirements that may exist in the material. The storage tank 31 is used to store different materials required for polylactic acid injection fillers. Each material corresponds to one storage tank 31, and can store materials such as polylactic acid raw materials, sodium carboxymethyl cellulose, mannitol, etc. Various components can be added to the storage tank 31 through the feeding pipe 36. After the first motor 33 is started, its output end drives the rotating shaft 32 to rotate. The stirring column 34 on the rotating shaft 32 will stir the materials in the storage tank 31 to prevent the materials from settling or clumping and ensure the uniformity of the materials. At the same time, the filter screen 35 on the rotating shaft 32 rotates with the rotating shaft 32. During the rotation, the filter screen 35 cooperates with the stirring column 34 to form a highly efficient stirring and filtration system. The stirring column 34 fully stirs the materials in the storage tank 31, making the materials in an active flow state, while the filter screen 35 shuttles through this flow of materials to filter and screen the materials.
[0023] Working principle: The storage tank 31 is used to store different materials required for polylactic acid injection filler. Each material corresponds to one storage tank 31. Materials can be added into the storage tank 31 through the feeding pipe 36. After the first motor 33 is started, its output end drives the rotating shaft 32 to rotate. The stirring column 34 on the rotating shaft 32 will stir the materials in the storage tank 31 to prevent the materials from settling and clumping, and ensure the uniformity of the materials. At the same time, the filter screen 35 on the rotating shaft 32 rotates with the rotating shaft 32. During the rotation, the filter screen 35 cooperates with the stirring column 34 to form a highly efficient stirring and filtration system. The stirring column 34 fully stirs the materials in the storage tank 31, making the materials in an active flow state, while the filter screen 35 shuttles through this flow of materials to filter and screen the materials.
[0024] When the solenoid valve 42 receives an electrical signal from the control board 4, it generates electromagnetic force based on the principle of electromagnetic induction, driving the valve to open. Different materials flow from the storage tank 31 into the mixing cylinder 2 through the transmission pipe 37. The control board 4 precisely controls the opening time and opening degree of the solenoid valve 42 according to the preset material dosage, so as to achieve precise control of the flow rate of each material. When the set material dosage is reached, the control board 4 sends a closing signal to the solenoid valve 42, and the solenoid valve 42 generates a reverse electromagnetic force to drive the valve to close, stopping the conveying of that material. This cycle continues until all materials are dispensed according to the set ratio, thereby realizing the automatic dispensing and metering process.
[0025] The mixing cylinder 2 is located below one side of the support plate 1. The transmission pipe 37 transports the material into the mixing cylinder 2 through the through groove 38. The second motor 21 starts, and its output end drives the rotating column 22 to rotate. Several stirring pieces 23 fixedly sleeved on the rotating column 22 rotate with the rotating column 22 to fully stir the various materials entering the mixing cylinder 2, so that the different materials are evenly mixed to form polylactic acid injection filler that meets the requirements.
