Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid filling equipment technology, and in particular to a constant pressure liquid filling machine. Background Technology
[0002] Traditional constant-pressure filling equipment uses the principle of air pressure balance to achieve liquid gravity filling, but this has shortcomings in practical applications. After filling, residual droplets from the filling head drip onto the equipment surface or the ground, causing material loss and contaminating the working environment. Furthermore, the complex internal piping structure requires disassembly of multiple parts for cleaning, resulting in a time-consuming rinsing process and increased maintenance costs. Therefore, a filling machine is needed that can collect residual droplets, reducing contamination, and is easy to clean. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as material loss, pollution of the working environment, and long rinsing time, by proposing a constant pressure liquid filling machine.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A constant pressure liquid filling machine includes a frame and a liquid storage tank fixedly installed above the working chamber of the frame;
[0006] A double-layer turntable is rotatably mounted on the inner wall of the bottom of the working cavity of the frame. The upper layer of the double-layer turntable has multiple placement holes, and the lower layer has multiple placement slots.
[0007] A filling head is located directly above one of the placement holes. A filling tube for liquid flow is fixedly connected between the filling head and the liquid storage tank. A connecting tube for gas flow is fixedly connected between the filling head and the liquid storage tank. The connecting end of the connecting tube and the liquid storage tank is located above the liquid surface.
[0008] The machine frame has a placement tray and a collection tray. A slide block is slidably provided on the inner wall of the working cavity of the frame. The placement tray is fixedly provided on the top of the slide block, and the collection tray is embedded inside the placement tray.
[0009] The electric telescopic rod is fixedly installed inside the frame. The bottom of the lower layer of the double-layer turntable has multiple through holes, which are respectively aligned and connected to multiple placement slots.
[0010] In one possible design, both the connecting pipe and the filling pipe are equipped with electrically controlled valves.
[0011] In one possible design, a fixed seat is fixedly installed on the inner wall of the working cavity of the frame, and the slide and the fixed seat are equipped with the same tension spring. The two ends of the tension spring are connected to the side wall of the slide and the side wall of the fixed seat respectively through hooks.
[0012] In one possible design, an abutment plate is fixedly provided on the outer wall of the telescopic shaft of the electric telescopic rod, and an inclined panel is fixedly provided on the side wall of the slide block, with the abutment plate engaging with the inclined surface of the inclined panel.
[0013] In one possible design, the bottom of the placement tray is fixedly connected to a drain pipe, which is connected to the outside via a flexible hose.
[0014] In one possible design, the bottom of the collection tray is fixedly connected to a connecting pipe, the connecting pipe is inserted into the drain pipe, and the end of the connecting pipe is threaded with a sealing plug.
[0015] In one possible design, a motor is fixedly installed inside the frame, and the output shaft of the motor drives a double-layer turntable.
[0016] In this application, during actual use, the operator places the filling bottle into the double-layer turntable through the placement slot and placement hole. The motor drives the double-layer turntable to rotate directly below the filling head. The electric telescopic rod is activated, and its telescopic shaft, passing through the through hole, lifts the filling bottle, ensuring a tight seal between the bottle mouth and the filling head. The valve on the connecting pipe opens, balancing the air pressure in the storage tank and the filling bottle; the valve on the filling pipe opens, allowing liquid to flow into the bottle under gravity. After filling is complete, the electric telescopic rod resets, and the filling bottle descends.
[0017] During the lifting process, the electric telescopic rod drives the contact plate to move. The contact plate cooperates with the inclined surface of the inclined plate to push the slide to move laterally, so that the collection tray is removed from under the filling head. During the reset, the tension spring pulls the slide to reset, and the collection tray moves to under the filling head to collect the dripping liquid.
[0018] When the collection tray is placed in the placement tray, its bottom connecting pipe will be inserted into the drain pipe for positioning and stability. When the filling machine needs to be cleaned, the collection tray is removed, the sealing plug is unscrewed, and then it is put back in its original position to connect the collection tray and the drain pipe. At this time, cleaning fluid is injected into the storage tank. The cleaning fluid flows through the filling pipe and filling head to the collection tray and finally is discharged through the drain pipe, thus achieving overall cleaning.
[0019] In this utility model, the constant pressure liquid filling machine can automatically avoid obstacles during filling and reset after filling by linking the collection tray with the filling head, thereby collecting any liquid that may drip after filling.
[0020] In this utility model, the constant pressure liquid filling machine, through the cleaning liquid circulation structure, can directly flush the storage tank during cleaning, and clean the pipes and the liquid collection tray together, which is simple and convenient.
[0021] In this invention, the residual droplets after filling can be effectively collected during use, and the cleaning difficulty can be reduced. Furthermore, the entire product can be cleaned during washing, thus reducing the difficulty of cleaning and making it more convenient. Attached Figure Description

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] In one embodiment: Reference Figure 1-2 A filling machine comprises components such as a frame 1, a liquid storage tank 2, a double-layer turntable 5, a filling head 9, a placement tray 10, and an electric telescopic rod 16.
[0029] The frame 1 serves as the main support, with a liquid storage tank 2 fixedly installed at the top of its working chamber and a double-layer turntable 5 mounted at the bottom via bearings. The liquid storage tank 2 is connected to the filling head 9 via a filling pipe 4, and simultaneously forms a pressure balance circuit with the filling head 9 via a connecting pipe 3. The inlet of the connecting pipe 3 and the liquid storage tank 2 is located above the liquid surface, ensuring gas flow while preventing liquid leakage.
[0030] The upper layer of the double-layer turntable 5 has multiple placement holes 8 evenly distributed to position the neck of the container, and the lower layer has multiple placement slots 6 correspondingly opened to support the bottom of the container. A through hole 7 is opened at the bottom of the lower layer for the electric telescopic rod 16 to pass through. The filling head 9 is fixed above the working chamber of the frame 1 and vertically aligned with one of the placement holes 8.
[0031] The electric telescopic rod 16 is installed inside the frame 1, and its telescopic shaft end can pass through the through hole 7 to directly lift the container.
[0032] In actual operation:
[0033] The operator first places the filling containers into the placement slots 6 and placement holes 8 of the double-layer turntable 5 in sequence;
[0034] Start the motor to drive the turntable to rotate, so that the target container is moved directly below the filling head 9;
[0035] Then the electric telescopic rod 16 is activated, and the telescopic shaft passes through the through hole 7 to lift the container, so that the container opening is tightly fitted with the lower end face of the filling head 9 to form a sealed space;
[0036] Then the electrically controlled valve of the connecting pipe 3 is opened, and the pressure in the storage tank 2 and the container is quickly balanced.
[0037] Open the electrically controlled valve of filling tube 4, and the liquid flows smoothly into the container under the action of gravity, thus completing the filling process;
[0038] After filling is completed, the electric telescopic rod 16 returns to its original position, and the container descends and detaches from the filling head 9.
[0039] This application can be used in the field of liquid filling equipment, or in other fields applicable to this application.
[0040] In another embodiment: Reference Figure 2 A constant pressure liquid filling machine is applied to the field of liquid filling equipment. The sliding seat 13 is slidably disposed in the working chamber, while the placement plate 10 is fixedly disposed on its top end, and the collection plate 11 is embedded in the top of the placement plate 10 for collecting the dripping liquid. The collection plate 11 can be circular, rectangular or polygonal in structure.
[0041] refer to Figure 3 Furthermore, a fixed seat 15 is fixedly provided on the inner wall of the working cavity, and the slide 13 and the fixed seat 15 are provided with the same tension spring, and the two ends of the tension spring are connected to the side wall of the slide 13 and the side wall of the fixed seat 15 respectively through hooks.
[0042] An abutment plate 14 is fixedly installed on the outer wall of the telescopic shaft of the electric telescopic rod 16, and an inclined plate 12 is fixedly installed on the side wall of the slide block 13. The abutment plate 14 and the inclined plate 12 cooperate with each other.
[0043] Specifically, during the lifting process, the electric telescopic rod 16 moves the contact plate 14, which engages with the inclined surface of the inclined panel 12, pushing the slide 13 to move laterally, causing the collection tray 11 to disengage from below the filling head 9. During resetting, the tension spring pulls the slide 13 back to its original position, and the collection tray 11 moves to below the filling head 9 to collect the dripping liquid. Furthermore, a gap exists between the top of the filling bottle and the bottom of the placement tray 10 to prevent contact between them.
[0044] refer to Figure 4 The bottom of the placement tray 10 is connected to the drain pipe 17. The bottom of the collection tray 11 is connected to the drain pipe 17 via a connecting pipe 19, and a sealing plug 18 is provided at the end of the connecting pipe 19 to control the drain channel.
[0045] Specifically, when the collection tray 11 is placed inside the placement tray 10, the connecting tube 19 at its bottom will be inserted into the drain tube 17 for positioning and to give it a certain degree of stability.
[0046] When the filling machine needs cleaning, the collection tray 11 is removed, the sealing plug 18 is unscrewed, and then it is put back in its original position, so that the collection tray 11 and the drain pipe 17 are connected to form a drain channel. At this time, cleaning fluid is injected into the inside of the storage tank 2. The cleaning fluid will flow through the filling pipe 4 to flush the machine, and then flow through the filling head 9 to the inside of the collection tray 11 to clean the collection tray 11. Finally, the cleaning fluid after flushing will be discharged outside the equipment through the drain pipe 17 and the connected hose, completing the online cleaning of the filling system.
[0047] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor and the electric telescopic rod 16 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0048] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
