Description

Technical Field

[0001] This utility model relates to the field of quantitative filling production technology, and in particular to a quantitative filling device for filling equipment. Background Technology

[0002] Filling equipment is a type of packaging machine. From the perspective of material packaging, it can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. From the perspective of automation, it can be divided into semi-automatic filling machines and fully automatic filling production lines. It mainly consists of finished product water pipes, water storage tanks, lifting filling valves, positioning assemblies, etc. After the bottle is positioned, the filling machine moves up and down under the action of a cylinder, and the opening and closing of the valve is controlled by the bottle nozzle limit. Product water is injected into the bottle through pipes, water tanks, and filling valves, ensuring filling accuracy, adjustable liquid level, and filling sealing. A quantitative filling machine is a type of filling equipment, generally including a frame, a liquid storage tank and its liquid level control device, a filling head including an exhaust channel and filling pipe, a container bottle conveying device, and a tray structure. Multiple filling heads and corresponding tray structures are usually set to improve filling efficiency. To improve the quantitative control capability of filling, the filling system usually uses measuring cups corresponding to each filling head for volume control.

[0003] Some existing quantitative filling equipment suffers from slow feeding rates and material residue on the inner walls of viscous materials during the filling process. This residue affects the accuracy of the filling process. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of some existing quantitative filling equipment in the process of filling viscous materials. Due to the stickiness of viscous materials, the feeding rate is slow during the filling process, and the viscous materials tend to stick to the inner wall of the filling equipment, resulting in material residue on the inner wall of the filling equipment and affecting the feeding accuracy. The invention provides a quantitative filling device for filling equipment.

[0005] The purpose of this utility model is achieved through the following technical solution: a quantitative filling device for filling equipment, including a cylindrical filling tank, a feeding pipe installed at the bottom of the filling tank, a hydraulic cylinder installed at the top of the filling tank, the lifting end of the hydraulic cylinder extending into the filling tank and installing a material extrusion block, and the two sides of the material extrusion block being slidably connected to the inner wall of the filling tank.

[0006] The side wall of the filling tank is equipped with two sets of transparent glass that are symmetrical about the filling tank. The side wall of the filling tank is equipped with photoelectric level gauges that correspond to the transparent glass. The infrared transmitter and infrared receiver of the photoelectric level gauges are located on one side of the two sets of transparent glass respectively. The feed end of the filling tank is equipped with a feed pipe and a feed pump. The feed pump is connected to the photoelectric level gauge signal. The feed end of the feed pipe is connected to an external raw material tank.

[0007] By setting up a hydraulic cylinder to drive the extrusion block to extrude material downwards during the discharge process from the filling tank, the material discharge efficiency can be effectively improved. Furthermore, by setting the two sides of the extrusion block to slide and connect with the inner wall of the filling tank, the material can be prevented from sticking to the side wall of the filling tank, ensuring the accuracy of the discharge. The combination of a feed pump, transparent glass and photoelectric level gauge can accurately measure the material in the filling tank.

[0008] A further technical solution is that the inner bottom wall of the filling tank is provided with an inclined part, and the bottom of the extrusion block is adapted to the inclined part of the inner bottom wall of the filling tank. By providing an inclined part to the inner bottom wall of the filling tank, the flowability of the material at the bottom can be improved, thereby effectively improving the material feeding efficiency. The adaptation of the bottom of the extrusion block to the inclined part of the inner bottom wall of the filling tank further avoids material residue at the bottom of the filling tank.

[0009] A further technical solution involves installing scale lines on the transparent glass corresponding to the photoelectric level gauge, and installing electric slides on both sides of the filling tank. The photoelectric level gauge is installed on the moving end of the electric slide. By setting the electric slide to move the photoelectric level gauge, the quantitative value of the material in the filling tank can be adjusted, which facilitates the quantitative filling of different volumes of material in the filling tank to meet different usage needs.

[0010] A further technical solution involves using a peristaltic pump as the feed pump and a photoelectric level gauge comprising a first level gauge and a second level gauge. The infrared transmitters and receivers of the first and second level gauges are located on one side of two sets of transparent glass, respectively. The first level gauge is positioned above the second level gauge, with a gap between them. Both the first and second level gauges are connected to the feed pump via signal transmission. By connecting the first and second level gauges to the feed pump, the first level gauge measures a fixed liquid level, while the second level gauge measures a certain distance below the fixed liquid level. When the second level gauge detects that the material has reached a certain distance below the first level gauge, it sends a signal to the feed pump to control the pump to reduce the material conveying rate. This slows down the feeding rate when the material is about to reach the fixed value of the first level gauge, preventing the material flow rate from being too fast and exceeding the fixed value of the first level gauge, thus avoiding inaccurate material feeding and further improving the accuracy of material feeding.

[0011] A further technical solution is to install a discharge valve and a vibration generator on the discharge pipe. The vibration generator is located below the discharge valve. The vibration generator can vibrate the discharge pipe, thereby preventing material from remaining on the inner wall of the discharge pipe and improving the discharge efficiency of the discharge pipe.

[0012] This utility model has the following advantages: By setting a hydraulic cylinder to drive the extrusion block to extrude material downwards during the discharge process of the filling tank, the material discharge efficiency can be effectively improved. Furthermore, by setting the two sides of the extrusion block to slide and connect with the inner wall of the filling tank, the material can be prevented from sticking to the side wall of the filling tank, ensuring the accuracy of material discharge. The combination of a feed pump, transparent glass and photoelectric level gauge can accurately measure the material in the filling tank. By setting an electric slide to drive the photoelectric level gauge to move, the quantitative value of the material in the filling tank can be adjusted, which is convenient for quantitative filling of different volumes of material in the filling tank to meet different usage needs.

[0022] like Figures 1-2 As shown, a quantitative filling device for filling equipment includes a cylindrical filling tank 1, a feeding pipe 8 installed at the bottom of the filling tank 1, a hydraulic cylinder 2 installed at the top of the filling tank 1, the lifting end of the hydraulic cylinder 2 extending into the filling tank 1 and installing a material extrusion block 3, and the two sides of the material extrusion block 3 are slidably connected to the inner wall of the filling tank 1.

[0023] The side wall of the filling tank 1 is equipped with two sets of transparent glass 6 that are symmetrical about the filling tank 1. The side wall of the filling tank 1 is equipped with photoelectric level gauges 7 that correspond to the transparent glass 6. The infrared transmitter and infrared receiver of the photoelectric level gauges 7 are located on one side of the two sets of transparent glass 6 respectively. The feed end of the filling tank 1 is equipped with a feed pipe 4 and a feed pump 5. The feed pump 5 is connected to the photoelectric level gauge 7. The feed end of the feed pipe 4 is connected to an external raw material tank.

[0024] By setting up a hydraulic cylinder 2 to drive the extrusion block 3 to extrude material downwards during the discharge process of filling tank 1, the material discharge efficiency can be effectively improved. Furthermore, by setting the two sides of the extrusion block 3 to slide and connect with the inner wall of filling tank 1, the material can be prevented from sticking to the side wall of filling tank 1, ensuring the accuracy of material discharge. The combination of feed pump 5, transparent glass 6 and photoelectric level gauge 7 can accurately measure the material in filling tank 1.

[0025] The bottom wall of the filling tank 1 is provided with an inclined part, and the bottom of the extrusion block 3 is adapted to the inclined part of the bottom wall of the filling tank 1. By providing an inclined part to the bottom wall of the filling tank 1, the flowability of the material at the bottom can be improved, thereby effectively improving the material feeding efficiency. The bottom of the extrusion block 3 is adapted to the inclined part of the bottom wall of the filling tank 1 to further prevent material residue at the bottom of the filling tank 1.

[0026] The transparent glass 6 is equipped with scale lines 11 corresponding to the photoelectric level gauge 7. Electric slides 12 are installed on both sides of the filling tank 1. The photoelectric level gauge 7 is installed on the moving end of the electric slide 12. By setting the electric slide 12 to drive the photoelectric level gauge 7 to move, the quantitative value of the material in the filling tank 1 can be adjusted, which makes it convenient for the filling tank 1 to quantitatively fill materials of different volumes to meet different usage needs.

[0027] The feed pump 5 is a peristaltic pump. The photoelectric level gauge 7 includes a first level gauge 701 and a second level gauge 702. The infrared transmitters and receivers of the first level gauge 701 and the second level gauge 702 are located on one side of the two sets of transparent glass 6, respectively. The first level gauge 701 is located above the second level gauge 702, and a gap is provided between the first level gauge 701 and the second level gauge 702. Both the first level gauge 701 and the second level gauge 702 are connected to the feed pump 5 via signal connection. The first level gauge 701 measures the quantitative liquid level, and the second level gauge 702 measures a certain distance below the quantitative liquid level. When the second level gauge 702 detects that the material has reached a certain distance below the first level gauge 701, the second level gauge 702 sends a signal to the feed pump 5 to control the feed pump 5 to reduce the rate of material delivery. This slows down the feeding rate when the material is about to reach the quantitative value of the first level gauge 701, thereby preventing the material flow rate from being too fast and exceeding the quantitative value of the first level gauge 701, which would cause inaccurate material feeding and further improve the accuracy of material feeding.

The vibration generator 10 can vibrate the discharge pipe 8, thereby preventing material from remaining on the inner wall of the discharge pipe 8 and improving the discharge efficiency of the discharge pipe 8.
