Abstract
Description
Technical Field
[0001] This utility model relates to a metering structure, specifically a numerically controlled adjustable vibration metering structure. Background Technology
[0002] In the transportation of powdery industrial raw materials, metering structures are crucial, as they control the amount of material stored in the final packaging bag. Therefore, the metering structure must ensure accuracy. However, due to the tendency of powdery raw materials to clump, the metering structure is prone to errors during operation, affecting the accuracy of the final packaging.
[0003] In addition, different packaging specifications require different measurement sizes, and the existing measurement structure cannot adjust the measurement size without stopping the machine, making it inconvenient to use. Utility Model Content
[0004] The main purpose of this utility model is to provide a numerically controlled adjustable vibration metering structure, which solves the technical problems of existing metering structures such as inaccurate measurement, easy generation of errors, and inability to adjust the measurement magnitude during operation.
[0005] To achieve the above objectives, this utility model provides a numerically controlled adjustable vibration metering structure, including a two-stage vibration feeding unit and a metering structure;
[0006] The metering structure includes an air blowing device, a turntable, and a guide cylinder. The turntable has multiple vertically placed metering cup holes, which are evenly distributed in a circular pattern. A guide cylinder is pressed on the top of each metering cup hole and is connected to the metering cup hole. The guide cylinder does not rotate with the turntable. The turntable has an air vent that is connected to the metering cup hole and the air blowing device. The air blowing device blows high-pressure air into the air vent, and then the high-pressure air passes through the metering cup hole and the guide cylinder in sequence, and is discharged from the top of the guide cylinder.
[0007] The secondary vibration feeding unit includes a secondary vibration electromagnet and a secondary vibration plate. The secondary vibration plate is fixedly connected to the top of the secondary vibration electromagnet, and the discharge end of the secondary vibration plate is suspended above the turntable.
[0008] Preferably, the metering structure also includes a worktable, a rotating shaft, and a motor;
[0009] A turntable is installed above the worktable, and a rotating shaft is connected to the middle of the turntable. The rotating shaft passes through the worktable and extends to the bottom of the worktable. The rotating shaft is connected to the motor drive.
[0010] Preferably, the turntable sidewall has multiple vents, the number of which is the same as the number of holes in the measuring cup;
[0011] The air blowing device is fixed to the top of the workbench, and the air blowing device connects to one air port at a time.
[0012] Preferably, the CNC adjustable vibration metering structure further includes a primary vibration feeding unit, which includes a primary vibration electromagnet and a primary vibration plate. The primary vibration electromagnet is fixed on the top of the workbench, and the primary vibration plate is fixedly connected to the top of the primary vibration electromagnet. The discharge end of the primary vibration plate is suspended above the feed end of the secondary vibration plate. The primary vibration plate is inclined, and the feed end of the primary vibration plate is higher than the discharge end of the primary vibration plate.
[0013] The secondary vibratory feeder is tilted, with the feed end higher than the discharge end, and the secondary vibratory electromagnet is fixed to the top of the worktable.
[0014] Preferably, a material hopper is suspended above the feed end of the primary vibratory feeder.
[0015] The beneficial effects achieved by this utility model are as follows:
[0016] This invention utilizes a two-stage vibrating feeding unit to feed materials in a vibrating manner, achieving uniform feeding speed and preventing material adhesion. By adjusting the vibration frequency and voltage of the two-stage vibrating electromagnet, the material is evenly fed onto the turntable. This method also allows for adjustment of the flow rate of the material entering the turntable, thus achieving the purpose of adjusting the metering size. Furthermore, this invention can also adjust the metering size by utilizing the number of metering cup holes that rotate during each filling process.
[0017] By setting up a primary vibration feeding unit, the material flow rate can be further controlled, and the material can be fed onto the turntable more evenly. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0023] like Figure 1 As shown, this utility model discloses a numerically controlled adjustable vibration metering structure, including a two-stage vibration feeding unit 1 and a metering structure 2. The metering structure 2 includes an air blowing device 21, a turntable 22, and a guide cylinder 23. The turntable 22 has multiple vertically arranged metering cup holes 221 for holding metered materials. The multiple metering cup holes 221 are arranged in a circumferential, equally spaced pattern, and the circumference is concentric with the turntable 22. A guide cylinder 23 is pressed onto the top of the metering cup holes 221. A packaging bag (not shown) is fitted onto the top of the guide cylinder 23, and a guide channel is provided in the middle of the guide cylinder 23. As the turntable 22 rotates, the metering cup holes 221 can communicate with the guide channel. Therefore, the guide cylinder 23 is only pressed onto the top of the turntable 22 by external force and does not rotate with the turntable 22. A support frame or similar structure can be used to suspend the guide cylinder 23 on the top of the turntable 22. The turntable 22 has multiple air vents 222, the number of which is the same as the number of metering cup holes 221. Each air vent 222 is connected to a metering cup hole 221. Preferably, the metering cup hole 221 is located on the side wall of the turntable 22. The air vents 222 are connected to an air blowing device 21, which contains a high-speed solenoid valve. In use, the high-speed solenoid valve opens, and high-pressure airflow enters the air vent 222 from the air inlet device. The high-pressure airflow then passes through the metering cup hole 221 and the guide cylinder 23 in sequence, and finally exits from the top of the guide cylinder 23. During this process, the high-pressure airflow can blow the material from the metering cup hole 221 into the guide cylinder 23, and finally into the packaging bag along with the high-pressure airflow. It is important to know that high-pressure gas enters the blowing device 21 from the inlet end. When the outlet end of the blowing device 21 is connected to the air vent 222 on the turntable 22, the air pressure at the inlet end and the outlet end of the blowing device 21 are different, forming a pressure difference. This triggers the high-speed electromagnet, causing the high-pressure gas to flow into the metering cup hole 221 through the air vent 222. Consequently, the material in the metering cup hole 221 containing the material enters the guide cylinder. The solenoid valve is a basic component for controlling fluids in automation and is common knowledge to those skilled in the art, so it will not be elaborated on here.
[0024] The secondary vibratory feeding unit 1 can evenly feed materials onto the turntable 22. The secondary vibratory feeding unit 1 includes a secondary vibratory electromagnet 11 and a secondary vibratory disk 12. The secondary vibratory disk 12 is fixedly connected to the top of the secondary vibratory electromagnet 11, and its discharge end is suspended above the turntable 22. To further facilitate material entry from the secondary vibratory disk 12 onto the turntable 22, the secondary vibratory disk 12 is inclined, with its feed end higher than its discharge end.
[0025] Please continue to refer to this. Figure 1 The metering structure 2 also includes a worktable 24, a rotating shaft 25, and a motor 26. The worktable 24 provides a working area for the metering structure 2 and is used to fix components such as the air blowing device 21. The air blowing device 21 is fixedly mounted on the top of the worktable 24, and it connects to one air inlet 222 at a time. A turntable 22 is positioned above the worktable 24, with a rotating shaft 25 connected to its center. The rotating shaft 25 drives the turntable 22 to rotate, extending through the worktable 24 to its lower surface. The rotating shaft 25 is connected to the motor 26. In use, the rotation of the motor 26 drives the rotating shaft 25 to rotate, which in turn drives the turntable 22 to rotate.
[0026] To further improve the uniformity of material feeding on the turntable 22, a primary vibration feeding unit 3 can be set up. The primary vibration feeding unit 3 includes a primary vibration electromagnet 31 and a primary vibration disk 32. The primary vibration electromagnet 31 is fixedly installed on the top of the worktable 24, and the primary vibration disk 32 is fixedly connected to the top of the primary vibration electromagnet 31. The primary vibration disk 32 is inclined, with its discharge end lower than its feed end. A material hopper is suspended above the feed end of the primary vibration disk 32, and the discharge end of the primary vibration disk 32 is suspended above the feed end of the secondary vibration disk 12.
[0027] The primary vibrating magnet 31 is activated, causing the primary vibrating disk 32 to vibrate. Material enters from the feed end of the primary vibrating disk 32 and moves towards the secondary vibrating disk 12 under the vibration of the primary vibrating disk 32 until it falls onto the secondary vibrating disk 12. Then, the secondary vibrating magnet 11 is activated, causing the secondary vibrating disk 12 to vibrate. The material moves towards the turntable 22 under the vibration of the secondary vibrating disk 32 until it falls onto the turntable 22, thus completing the material conveying from the primary vibrating disk 32 to the turntable 22. It should be noted that the working principle of the vibrating magnet involves a combination of electromagnetism and vibration mechanism, which is common knowledge to those skilled in the art and will not be elaborated upon here.
[0028] To enhance intelligence, the controller signals of the primary vibration electromagnet 31 and the secondary vibration electromagnet 11 can be connected to a PLC for digital-to-analog conversion, thereby achieving linear adjustment of vibration frequency and vibration voltage.
[0029] In operation, material enters the feed end of the primary vibrating plate 32 from the material hopper. The primary vibrating electromagnet 31 vibrates, driving the primary vibrating plate 32 to vibrate. The material falls evenly from the discharge end of the primary vibrating plate 32 into the feed end of the secondary vibrating plate 12. The secondary vibrating electromagnet 11 vibrates, driving the secondary vibrating plate 12 to vibrate. The material falls evenly from the discharge end of the secondary vibrating plate 12 into the metering cup orifice 221. When the material in the metering cup orifice 221 meets the requirements for one metering cycle, the motor 26 starts, driving the rotating shaft 25 to rotate, thereby driving the turntable 22 to rotate. When the metering cup orifice 221, filled with material, rotates to below the guide cylinder 23, the high-speed solenoid valve opens, and high-pressure airflow enters the metering cup orifice 221. The material is propelled into the packaging bag by the high-pressure airflow. When it is necessary to adjust the metering size, the flow speed of the material entering the turntable 22 can be adjusted by adjusting the vibration parameters; the metering size can also be adjusted by the number of meters in the metering cup orifice 221 that the turntable 22 rotates during each filling process.
[0030] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
