Description

Technical Field

[0001] This utility model relates to the field of liquid packaging technology, specifically to an anti-drip device for a liquid packaging machine. Background Technology

[0002] Liquid packaging machines can be classified into atmospheric pressure filling machines, pressure filling machines, and vacuum filling machines according to their filling principles. When packaging liquids, some liquid will remain at the outlet of the filling head after a single bottle is filled. When the filling head retracts and returns to its original position, the remaining liquid will drip, contaminating the filling environment and potentially dripping onto the packaging bottle.

[0003] Publication No. CN220149207U discloses an anti-drip device for a liquid packaging machine. By installing an anti-drip component between the packaging bottle and the dispensing pipe, when the dispensing pipe finishes injecting liquid into the packaging bottle and resets upwards, it can quickly absorb any residual liquid at the end of the dispensing pipe. If a large amount of residual liquid is absorbed, the liquid can be guided into a storage box and discharged promptly through a drain pipe. Therefore, during liquid packaging operations, when the dispensing pipe resets, residual liquid can be absorbed and collected in a timely manner, preventing leakage from contaminating the packaging bottle and the packaging environment. However, this patent still has the following problems in practical use:

[0004] By installing an anti-drip component between the packaging bottle and the dispensing tube, the residual liquid at the end of the dispensing tube can be quickly absorbed when it returns to its original position after injecting liquid into the packaging bottle. If a large amount of residual liquid is absorbed, the liquid can be guided into the storage box and discharged in time through the drain pipe. Thus, during liquid packaging operations, when the dispensing tube returns to its original position, residual liquid can be absorbed and collected in time, avoiding leakage that could contaminate the packaging bottle and the packaging environment. However, when liquid drips onto the baffles, if the amount of residual liquid is small, the liquid may not be directly absorbed by the sponge pad. The liquid may remain in the center of the baffles. The thickened sealing part between each baffle may not be able to absorb the liquid. This will cause the dispensing tube to descend again and squeeze the baffles. When the liquid remaining in the center of each baffle is squeezed by the dispensing tube, it will separate and drip.

[0005] An anti-drip device for liquid packaging machines is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an anti-drip device for liquid packaging machines, addressing the problem described in the background art. Currently, the anti-drip component is installed between the packaging bottle and the dispensing pipe. When the dispensing pipe finishes injecting liquid into the bottle and returns to its original position, it can quickly absorb the residual liquid at the end of the dispensing pipe. If a large amount of residual liquid is absorbed, it can be directed into a storage box and discharged promptly through a drain pipe. This allows for timely absorption and collection of residual liquid during liquid packaging operations when the dispensing pipe returns to its original position, preventing leakage and contamination of the packaging bottle and environment. However, when liquid drips onto the baffles, if the residual liquid is small, it may not be directly absorbed by the sponge pad. Instead, the liquid may remain in the center of the baffles. While there are thickened sealing sections between the baffles, these sections may not be able to absorb the liquid. This causes the dispensing pipe to descend again, squeezing the baffles. The liquid remaining in the center of each baffle will separate and drip as the dispensing pipe squeezes the baffles.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drip-proof device for a liquid packaging machine, comprising a feeding pipe and a frame, wherein connecting blocks are symmetrically installed on both sides of the surface of the feeding pipe near the bottom;

[0008] A cylinder is fixedly installed on the bottom surface of the connecting block, and a liquid outlet pipe is fixedly connected to the bottom surface of the cylinder. A hole is opened in the middle of the interior of the frame.

[0009] Also includes:

[0010] Anti-drip components are symmetrically installed on both sides of the top surface of the platform;

[0011] The anti-drip component includes a mounting bracket that is fixedly connected to the stand;

[0012] An electric push rod is connected through the middle of the interior of the fixed frame.

[0013] Preferably, a stabilizing block is fixedly connected to one side surface of the electric push rod, and a sponge pad is attached to the side surface of the stabilizing block away from the electric push rod.

[0014] Preferably, sliders are symmetrically installed on both sides of the stabilizing block, and a sliding rod is connected through the middle of the slider, with both sides of the sliding rod fixedly connected to the fixing frame.

[0015] Preferably, a locking groove is provided on one side of the sponge pad, and a locking block is fixedly connected to the other side of the sponge pad.

[0016] Preferably, the engaging block engages with the engaging slot.

[0017] Preferably, a mounting plate is bonded to the bottom surface of the sponge pad, and threaded rods are threaded through the bottom surface of the mounting plate. Anti-loosening nuts are threaded onto the surface of the threaded rods, and the top surface of the mounting plate is fitted and connected to the stabilizing block.

[0018] Preferably, the bottom surface of the stabilizing block is symmetrically provided with threaded grooves on one side, and the threaded grooves are threadedly connected to the threaded insert rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This anti-drip device for a liquid packaging machine, by setting an anti-drip component, ensures that the liquid dripping from the outlet pipe will directly drip onto the sponge pad after the two semi-circular sponge pads are engaged to form a circle. The sponge pad absorbs the liquid, and the circular sponge pad and the outlet pipe are perpendicular to each other, thus ensuring that when liquid drips from the outlet pipe, it drips directly onto the sponge pad and does not drip elsewhere. The specific details are as follows:

[0020] 1. By incorporating an anti-drip component, when the cylinder, under the control of the control terminal, drives the outlet pipe to rise and retract, two electric actuators are simultaneously activated. The output ends of these actuators move the stabilizing block and the sponge pad. Slider blocks are connected to both sides of the stabilizing block, and the sliders and sliding rods are connected through a sliding connection. The cooperation between the sliders and the sliding rods provides support for the stabilizing block. Since the lag of the electric actuator is less than that of the cylinder, the electric actuator starts slightly slower than the cylinder. However, after the cylinder drives the outlet pipe back to its original position… The electric push rod drives the two stabilizing blocks and the sponge pad to fit together. At the same time, there are locking grooves and locking blocks between the two stabilizing blocks. The locking grooves and locking blocks on the two stabilizing blocks are aligned opposite to each other. This means that when the two stabilizing blocks are fitted together, the locking grooves and locking blocks on the two stabilizing blocks engage respectively. The sponge pad forms a circle and is located at the center of the liquid outlet tube. This allows the liquid to drip directly onto the sponge pad when it drips from the liquid outlet tube, thereby absorbing the liquid and preventing leakage from contaminating the packaging bottle and the packaging environment.

[0021] 2. By using a mounting plate, threaded rod, anti-loosening nut, and threaded groove, when the sponge pad needs to be replaced after prolonged use, the anti-loosening nut is rotated using a tool to separate it from the threaded rod. Then, the threaded rod is rotated again to separate it from the threaded groove, allowing the mounting plate and sponge pad to be removed. The sponge pad is connected to the mounting plate via Velcro, facilitating pad replacement. After the sponge pad is adhered to the mounting plate, the sponge pad and mounting block are attached to the retaining block. The threaded rod is then screwed into the threaded groove, and the anti-loosening nut is threaded onto the threaded rod. This causes the anti-loosening nut to press against the mounting plate, ensuring a tight fit between the mounting plate and the retaining block, thus completing the replacement of the mounting plate and sponge pad.

Detailed Implementation

[0028] 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.

[0029] Please see Figure 1-5This utility model provides a technical solution: an anti-drip device for a liquid packaging machine, comprising a feeding pipe 1 and a frame 5, wherein connecting blocks 2 are symmetrically installed on both sides of the surface of the feeding pipe 1 near the bottom; a cylinder 3 is fixedly installed on the bottom surface of the connecting block 2, and a liquid outlet pipe 4 is fixedly connected to the bottom surface of the cylinder 3; a hole 6 is opened in the middle of the interior of the frame 5; further comprising: anti-drip components 7 symmetrically installed on both sides of the top surface of the frame 5; wherein the anti-drip component 7 includes a fixing frame 701 fixedly connected to the frame 5; wherein an electric push rod 702 is penetrated through the middle of the interior of the fixing frame 701, such as Figure 1-5 As shown, by setting up the anti-drip component 7, after the two semi-circular sponge pads 704 are engaged to form a circle, the liquid dripping from the outlet pipe 4 will directly drip onto the sponge pad 704, thereby absorbing the liquid. At the same time, the sponge pad 704 and the outlet pipe 4 are perpendicular to each other, which ensures that when the liquid drips from the outlet pipe 4, it can directly drip onto the sponge pad 704 and not drip onto other places. Meanwhile, the cylinder 3 is electrically connected to the control terminal, and the feed pipe 1 and the outlet pipe 4 are telescopically sleeved. A sealing element is set at the sliding position of the feed pipe 1 and the outlet pipe 4 to prevent liquid leakage.

[0030] A stabilizing block 703 is fixedly connected to one side surface of the electric actuator 702. A sponge pad 704 is attached to the side surface of the stabilizing block 703 away from the electric actuator 702. Slider blocks 705 are symmetrically installed on both sides of the stabilizing block 703. A sliding rod 706 is connected through the middle of the interior of each slider 705. Both sides of the sliding rod 706 are fixedly connected to the fixing frame 701. A locking groove 707 is provided on one side of the sponge pad 704. A locking block 708 is fixedly connected to the other side of the sponge pad 704. The locking block 708 engages with the locking groove 707. Figure 2 , 3As shown, two electric actuators 702 are simultaneously activated via the control terminal, causing the output ends of the electric actuators 702 to move the stabilizing block 703 and the sponge pad 704. Slider blocks 705 are connected to both sides of the stabilizing block 703, and the sliders 705 and the sliding rod 706 are connected by a through-sliding connection. Through the cooperation between the sliders 705 and the sliding rod 706, the stabilizing block 703 is supported. Since the lag of the electric actuator 702 is less than that of the cylinder 3, the starting of the electric actuator 702 is slightly slower than that of the cylinder 3. However, after the cylinder 3 moves the outlet pipe 4 back to its original position, the electric actuator 702 just causes the two stabilizing blocks 703 and the sponge pad 704 to fit together. Each of the two fixed blocks 703 has a locking groove 707 and a locking block 708. The locking grooves 707 and locking blocks 708 on the two fixed blocks 703 are aligned opposite to each other. This means that when the two fixed blocks 703 are attached, the locking grooves 707 and locking blocks 708 on the two fixed blocks 703 engage respectively. The sponge pad 704 forms a circle and is located at the center of the liquid outlet tube 4. This allows the liquid to drip directly onto the sponge pad 704 when liquid drips from the liquid outlet tube 4, thereby absorbing the liquid and preventing leakage from contaminating the packaging bottle and the packaging environment. The electric push rod 702 is model LAM33-A and is electrically connected to the control end.

[0031] A mounting plate 8 is adhesively connected to the bottom surface of the sponge pad 704. Threaded rods 9 are threaded through the bottom surface of the mounting plate 8, and anti-loosening nuts 10 are threaded onto the surface of the threaded rods 9. The top surface of the mounting plate 8 is fitted to the stabilizing block 703. Threaded grooves 11 are symmetrically formed on one side of the bottom surface of the stabilizing block 703, and the threaded grooves 11 are threadedly connected to the threaded rods 9. Figure 4 , 5As shown, by setting the mounting plate 8, threaded rod 9, anti-loosening nut 10 and threaded groove 11, when the sponge pad 704 needs to be replaced after long-term use, the anti-loosening nut 10 can be rotated by using a tool. The anti-loosening nut 10 is separated from the threaded rod 9. Then, by using a tool to rotate the threaded rod 9, the threaded rod 9 is separated from the threaded groove 11, thereby allowing the mounting plate 8 and the sponge pad 704 to be removed. The sponge pad 704 is connected to the mounting plate 8 by Velcro, which facilitates the replacement of the sponge pad 704. After the sponge pad 704 is glued to the mounting plate 8, the sponge pad 704 and the mounting block and the stabilizing block 703 are attached. The threaded rod 9 is screwed into the threaded groove 11, and then the anti-loosening nut 10 is threaded onto the threaded rod 9, so that the anti-loosening nut 10 presses against the mounting plate 8, thereby making the mounting plate 8 and the stabilizing block 703 fit tightly together, thus completing the replacement of the mounting plate 8 and the sponge pad 704. The threaded rod 9 and the anti-loosening nut 10 can be made of stainless steel, or they can be coated with anti-corrosion and anti-rust paint as needed.

[0032] Working principle: Before using this anti-drip device for liquid packaging machines, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, after the liquid outlet pipe 4 has finished filling the tank, the cylinder 3, under the control of the control terminal, drives the liquid outlet pipe 4 to rise and retract. Simultaneously, the control terminal activates two electric push rods 702, causing the output ends of the electric push rods 702 to move the stabilizing block 703 and the sponge pad 704. Slider blocks 705 are connected to both sides of the stabilizing block 703, and the sliders 705 and the sliding rods 706 are connected by a through-sliding connection. Through the cooperation between the sliders 705 and the sliding rods 706, the stabilizing block 703 can be supported. Since the lag of the electric push rod 702 is less than that of the cylinder 3, the starting of the electric push rod 702 is one step slower than that of the cylinder 3. However, when the cylinder 3 drives the liquid outlet pipe 4 to return to its original position... After repositioning, the electric push rod 702 drives the two stabilizing blocks 703 and the sponge pad 704 to fit together. At the same time, each of the two stabilizing blocks 703 has a locking groove 707 and a locking block 708. The locking groove 707 and the locking block 708 on the two stabilizing blocks 703 are aligned opposite to each other. This means that when the two stabilizing blocks 703 are fitted together, the locking groove 707 and the locking block 708 on the two stabilizing blocks 703 engage respectively. The sponge pad 704 forms a circle and is located at the center of the liquid outlet pipe 4. This allows the liquid to drip directly onto the sponge pad 704 when it drips from the liquid outlet pipe 4, thereby absorbing the liquid and preventing leakage from contaminating the packaging bottle and the packaging environment.

[0033] Secondly, by setting up the mounting plate 8, threaded rod 9, anti-loosening nut 10, and threaded groove 11, when the sponge pad 704 needs to be replaced after prolonged use, the anti-loosening nut 10 is rotated using a tool to separate it from the threaded rod 9. Then, the threaded rod 9 is rotated using a tool to separate it from the threaded groove 11, allowing the mounting plate 8 and sponge pad 704 to be removed. The sponge pad 704 is connected to the mounting plate 8 by Velcro, which facilitates the replacement of the sponge pad 704. After the sponge pad 704 is adhered to the mounting plate 8, the sponge pad 704 and the mounting block 703 are attached together. The threaded rod 9 is screwed into the threaded groove 11, and the anti-loosening nut 10 is threaded onto the threaded rod 9, causing the anti-loosening nut 10 to press against the mounting plate 8, thus ensuring a tight fit between the mounting plate 8 and the fixing block 703, thereby completing the replacement of the mounting plate 8 and sponge pad 704.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
