Description

Technical Field

[0001] This application relates to the field of filling machine technology, and in particular to an automatic quantitative filling machine. Background Technology

[0002] Automatic quantitative filling technology is widely used in food, pharmaceutical, chemical, and daily chemical industries. Its core function is to accurately inject liquid into packaging containers according to a preset amount. Compared with traditional manual filling, automatic quantitative filling has the advantages of high work efficiency and low production cost.

[0003] One type of automatic quantitative filling machine includes a fixed base, a filling component, and a gravity sensor. The filling component fills a container placed on the fixed base with liquid products, and the gravity sensor detects the weight of the container and the liquid, thereby achieving quantitative filling of the liquid.

[0004] However, the existing automatic quantitative filling machine has a low accuracy in liquid quantitative filling because the gravity sensor has a response time lag during operation and is affected by the impact force of the liquid on the container during filling. Utility Model Content

[0005] In order to reduce the problem of low filling accuracy in automatic quantitative filling machines, this application provides an automatic quantitative filling machine.

[0006] This application provides an automatic quantitative filling machine, which adopts the following technical solution: An automatic quantitative filling machine includes: A fixed base is fixedly installed on the ground. The support frame is vertically fixed on the fixed base, and two sets of support frames are symmetrically arranged along the center line of the width direction of the fixed base. The drive assembly is mounted on the support frame, and two sets of drive assemblies are provided corresponding to the support frame. A filling assembly, one end of which is fixed to the moving end of a drive assembly, is used to fill containers with liquid products.

[0007] By adopting the above technical solution, the fixed base provides installation space for the support frame, and the support frame provides installation space for the drive component and the filling component. The two sets of support frames, drive components, and filling components are respectively set at both ends of the fixed base along its length. Filling is performed by the two sets of filling components, which improves filling efficiency. The drive component can drive the filling component to move along the height direction of the support frame, thereby controlling the height of the filling component and allowing it to extend into the interior of the container. This reduces the probability of liquid splashing during filling and reduces liquid waste. The filling component can quantitatively fill the container. By using the drive component and the filling component together, precise quantitative filling of the container is achieved.

[0008] Optionally, the driver components include: The slide rail is vertically fixed on the support frame, and a vertical groove is provided on the slide rail; The motor is vertically fixed on the slide rail, and the output end of the motor extends through the slide rail into the slide groove. A threaded rod is vertically installed in the slide groove. One end of the threaded rod is rotatably connected to the slide rail, and the other end of the threaded rod is fixedly connected to the output end of the motor. The slider is embedded in the groove and is threadedly connected to the threaded rod.

[0009] By adopting the above technical solution, the slide rail provides installation space for the motor, threaded rod, and slider. The rotation of the motor's output end can drive the threaded rod to rotate synchronously. Because the threaded rod is threadedly connected to the slider, the rotation of the threaded rod can drive the slider to move along the axis of the threaded rod. The movement of the slider can drive the filling component to move synchronously, thereby enabling the filling component to extend into the container for precise filling and improving the filling accuracy of the automatic quantitative filling machine.

[0010] Optionally, the filling components include: A control valve block is fixedly mounted on a support frame. A control valve is installed on the control valve block. One end of the control valve block is connected to the liquid source through a pipe. The flow control valve is fixedly mounted on the slider and has a control panel. The upper end of the flow control valve is connected to the output end of the control valve block through a pipe. The filling tube is vertically fixed at the lower end of the flow control valve.

[0011] By adopting the above technical solution, the control valve block can restrict the liquid flowing out of the liquid source. The operator can control the opening or closing of the control valve block by controlling the valve, which improves the operator's control over the liquid flowing through the automatic quantitative filling machine. The operator can set the filling volume of the flow control valve through the control panel, thereby achieving precise quantitative filling of the liquid. The filling tube can be extended into the container under the drive of the drive component, so that the liquid can flow smoothly into the container, reducing the risk of splashing during the liquid filling process and further improving the stability and accuracy of filling.

[0012] Optionally, a limit hole is vertically provided on the fixed base, and a limit plate is provided on the limit hole.

[0013] By adopting the above technical solution, the setting of the limiting plate enables the staff to quickly position and fix the container to be filled, reducing the risk of container displacement or tilting during the filling process and improving the filling stability of the automatic quantitative filling machine when filling the container.

[0014] Optionally, multiple sets of limiting holes are provided at intervals along the length of the fixed base.

[0015] By adopting the above technical solution, the setting of multiple sets of limiting holes allows the operator to select the appropriate installation position of the limiting plate according to the size and opening end of the container, thereby enabling the automatic quantitative filling machine to adapt to containers of different specifications for filling operations and improving the applicability of the automatic quantitative filling machine.

[0016] Optionally, the support frame is provided with inclined beams around its perimeter, one end of which is fixedly connected to the support frame and the other end of which is fixedly connected to the fixed base.

[0017] By adopting the above technical solution, the inclined beam can improve the structural stability between the support frame and the fixed base, so that the filling component remains stable during filling and reduces the impact of vibration generated during the use of the filling component on the filling accuracy.

[0018] Optional, the pipe is a corrugated pipe.

[0019] By adopting the above technical solution, the corrugated pipe design enables the drive assembly to maintain the continuity and flexible connection of the liquid delivery channel when it drives the filling assembly to move, reducing the probability of leakage or damage at the pipe connection and extending the service life of the automatic quantitative filling machine.

[0020] Optionally, a liquid level sensor is vertically installed around the periphery of the filling tube.

[0021] By adopting the above technical solution, the liquid level sensor can monitor the liquid level in the container. When the liquid level reaches the preset height, the system automatically sends a signal and closes the flow control valve, effectively reducing the probability of liquid overflow and improving the automation and safety of the filling process.

[0022] In summary, the present invention provides an automatic quantitative filling machine, which has at least one of the following beneficial technical effects: 1. The fixed base provides installation space for the support frame, which in turn provides installation space for the drive assembly and filling assembly. Two sets of support frames, drive assemblies, and filling assemblies are respectively located at both ends of the fixed base along its length. Filling is performed by two sets of filling assemblies, improving filling efficiency. The drive assembly can drive the filling assembly to move along the height of the support frame, thereby controlling the height of the filling assembly and allowing it to extend into the interior of the container. This reduces the probability of liquid splashing during filling and minimizes liquid waste. The filling assembly can quantitatively fill the container. Through the combined use of the drive assembly and the filling assembly, precise quantitative filling of the container is achieved.

[0023] 2. The liquid level sensor can monitor the liquid level in the container. When the liquid level reaches the preset height, the system automatically sends a signal and closes the flow control valve, which effectively reduces the probability of liquid overflow and improves the automation and safety of the filling process.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] Combination Figure 1 , Figure 2 and Figure 3 This application discloses an automatic quantitative filling machine, including: a fixed base 11, a support frame 12, a drive assembly 2, and a filling assembly 3; the fixed base 11 is fixedly installed on the ground, the support frame 12 is vertically fixedly installed on the fixed base 11, and two sets of support frames 12 are symmetrically arranged along the center line of the width direction of the fixed base 11; the drive assembly 2 is installed on the support frame 12, and two sets of drive assemblies 2 and support frames 12 are correspondingly arranged; one end of the filling assembly 3 is fixed to the moving end of the drive assembly 2, and the filling assembly 3 is used to fill liquid products into containers.

[0027] In this embodiment, the fixed base 11 is rectangular and provides installation space for the support frame 12. The support frame 12 is inverted L-shaped and provides installation space for the drive assembly 2 and the filling assembly 3. An inclined beam 14 is provided around the support frame 12. One end of the inclined beam 14 is fixedly connected to the support frame 12, and the other end is fixedly connected to the fixed base 11. The inclined beam 14 improves the structural stability between the support frame 12 and the fixed base 11, ensuring the filling assembly 3 remains stable during filling and reducing the impact of vibrations generated during use on filling accuracy. A limit hole 41 is vertically provided on the fixed base 11. The limit hole 41 is cylindrical and has a limit plate 13. The limit plate 13 is L-shaped and is fixedly installed on the fixed base 11 by bolts. The automatic quantitative filling machine can quickly position and fix the container to be filled. Multiple sets of limiting holes 41 are arranged at intervals along the length of the fixed base 11. The operator can fix the limiting plate 13 on different limiting holes 41 of the fixed base 11, thereby changing the distance between the limiting plates 13. This allows the limiting plate 13 to be installed in a suitable position according to the size and opening of the container, thus making the automatic quantitative filling machine adaptable to containers of different specifications for filling operations and improving the applicability of the automatic quantitative filling machine. The drive component 2 can drive the filling component 3 to move along the height direction of the support frame 12, so that the filling component 3 extends into the container. The filling component 3 can fill the container with a quantitative amount of liquid. By using the drive component 2 and the filling component 3 together, the probability of liquid splashing during filling is reduced, and liquid waste during filling is reduced, thereby achieving accurate quantitative filling of the container.

[0028] In actual use, the staff fixes the container on the fixed base 11 by using the limiting plate 13. The staff operates the drive component 2 to drive the filling component 3 to extend into the container. The filling component 3 starts to inject a certain amount of liquid product into the container according to the preset parameters.

[0029] Combination Figure 1 , Figure 2 and Figure 3 In one specific embodiment, the drive assembly 2 includes: a slide rail 21, a motor 22, a threaded rod 23, and a slider 24; the slide rail 21 is vertically fixed on the support frame 12, and a slide groove 42 is vertically provided on the slide rail 21; the motor 22 is vertically fixed on the slide rail 21, and the output end of the motor 22 extends through the slide rail 21 into the slide groove 42; the threaded rod 23 is vertically provided in the slide groove 42, one end of the threaded rod 23 is rotatably connected to the slide rail 21, and the other end of the threaded rod 23 is fixedly connected to the output end of the motor 22; the slider 24 is embedded in the slide groove 42, and the slider 24 is threadedly connected to the threaded rod 23.

[0030] In this embodiment, the slide rail 21 is rectangular, the slide groove 42 is rectangular, and the slider 24 is T-shaped. One end of the slider 24 is embedded in the slide groove 42, and the other end of the slider 24 extends outside the slide groove 42. The rotation of the output end of the motor 22 is not affected by the slide rail 21. The threaded rod 23 is cylindrical. The rotation of the output end of the motor 22 can drive the threaded rod 23 to rotate synchronously. Because the threaded rod 23 and the slider 24 are threadedly connected, the rotation of the threaded rod 23 can drive the slider 24 to slide along the axis of the threaded rod 23, thereby achieving the purpose of controlling the filling component 3 on the slider 24 to move synchronously along the axis of the threaded rod 23. This allows the filling component 3 to extend into the container during filling, reducing the probability of liquid splashing during filling and improving the filling accuracy of the automatic quantitative filling machine.

[0031] In actual use, the staff starts the motor 22. The rotation of the motor 22 drives the threaded rod 23 to rotate synchronously. The rotation of the threaded rod 23 drives the slider 24 to move along the axis of the threaded rod 23. The movement of the slider 24 drives the filling component 3 to move synchronously and extend into the container to carry out the filling operation.

[0032] Combination Figure 1 , Figure 2 and Figure 3 In one specific embodiment, the filling assembly 3 includes: a control valve block 31, a flow control valve 32, and a filling pipe 33. The control valve block 31 is fixedly mounted on the support frame 12, and a control valve 15 is provided on the control valve block 31. One end of the control valve block 31 is connected to the liquid source through a pipe 18. The flow control valve 32 is fixedly mounted on the slider 24, and a control panel 16 is provided on the flow control valve 32. The upper end of the flow control valve 32 is connected to the output end of the control valve block 31 through a pipe 18. The filling pipe 33 is vertically fixedly mounted on the lower end of the flow control valve 32.

[0033] In this embodiment, one end of the control valve block 31 is connected to the liquid source via pipe 18, and the other end of the control valve block 31 is connected to the input end of the flow control valve 32 via pipe 18. Pipe 18 is a bellows, a flexible pipe, which ensures that the pipe 18 remains connected and unaffected by stretching during the movement of the slider 24 and the flow control valve 32. This allows the flow control valve 32 to maintain a stable liquid supply, enabling continuous filling. The operator can control the liquid to flow into the flow control valve 32 along the pipe 18 via control valve 15, improving the operator's control over the liquid in the automatic quantitative filling machine. The operator can control the liquid flow rate of the flow control valve 32 via control panel 16, thereby precisely controlling the flow of liquid during filling. The control valve block 31 and the flow control valve 32 are in operation. The principle is existing technology in the field, so it will not be specifically described in this embodiment. The filling tube 33 is cylindrical, and the lower end of the filling tube 33 is provided with an inclined surface to facilitate the insertion of the filling tube 33 into the container. A liquid level sensor 17 is vertically arranged around the filling tube 33. The liquid level sensor 17 can detect the height of the liquid in the container. When the liquid level sensor 17 detects that the liquid level in the container reaches a preset height, the liquid level sensor 17 can transmit a signal to the control panel 16 of the flow control valve 32. After receiving the signal, the flow control valve 32 automatically closes and stops the liquid supply. The detection principle of the liquid level sensor 17 is existing technology in the field, so the detection principle of the liquid level sensor 17 will not be specifically described in this embodiment. Through the combined action of the flow control valve 32 and the liquid level sensor 17, the accuracy and automation of automatic quantitative filling are improved.

[0034] In practical use, before using the automatic quantitative filling machine, the operator opens the control valve 15 on the control valve block 31. The liquid is transported to the flow control valve 32 through the pipeline 18. The operator sets the filling parameters of the flow control valve 32 through the control panel 16. When the filling tube 33 enters the container under the action of the slider 24, the flow control valve 32 starts to supply liquid according to the set parameters. The liquid flows into the container through the filling tube 33. When the liquid level sensor 17 detects that the liquid level in the container reaches the preset value and the flow rate of the flow control valve 32 reaches the preset value, the flow control valve 32 automatically closes and stops filling. The slider 24 then drives the filling assembly 3 to reset.

[0035] The implementation principle of this application is as follows: The operator fixes the container on the fixed base 11 using the limiting plate 13. The operator sets the filling parameters of the flow control valve 32 through the control panel 16. The operator opens the control valve 15 on the control valve block 31 and starts the motor 22. The rotation of the motor 22 drives the threaded rod 23 to rotate synchronously. The rotation of the threaded rod 23 drives the slider 24 to move along the axis of the threaded rod 23. The movement of the slider 24 drives the filling assembly 3 to move synchronously and extend into the container. The flow control valve 32 starts to supply liquid according to the set parameters. The liquid flows into the container through the filling pipe 33. When the liquid level sensor 17 detects that the liquid level in the container reaches the preset value and the flow rate of the flow control valve 32 reaches the preset value, the flow control valve 32 automatically closes and stops filling. The slider 24 then drives the filling assembly 3 to reset.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
