Description

Technical Field

[0001] This utility model relates to the technical field of self-cleaning devices for conveying pipes, and in particular to a self-cleaning device for the conveying pipes of filling machines based on pulse air pressure.

[0002] Background technology.

[0003] Filling machines, as key equipment on production lines in industries such as food, beverage, daily chemicals, and pharmaceuticals, play a crucial role in accurately conveying and filling liquids, pastes, and other materials into packaging containers. Their efficient and stable operation directly impacts product quality and production efficiency. In the filling machine's workflow, the feed pipe, as the material transport channel, plays an indispensable role. However, in actual production, material residue easily accumulates on the inner wall of the feed pipe, especially for highly viscous materials or those containing particles. This residue gradually builds up, leading to blockages. Once the feed pipe is blocked, it not only affects the normal material transport, causing inaccurate filling volumes and reducing product qualification rates, but it can also cause equipment malfunctions due to abnormal pressure, increasing maintenance costs and downtime, severely impacting the continuous operation of the production line and the company's economic benefits.

[0004] To solve the problem of clogging in the feed pipe, traditional cleaning methods often involve manual disassembly and cleaning or simple rinsing. However, these methods suffer from low efficiency, incomplete cleaning, and high labor intensity.

[0005] Therefore, this application provides a self-cleaning device for the filling machine feed pipe based on pulse air pressure. Utility Model Content

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figures 1 to 4 As shown, this application provides a self-cleaning device for the filling machine's feed pipe based on pulse air pressure, comprising:

[0028] The self-cleaning device 100 includes a cleaning mechanism 10, a control mechanism 30, a recycling mechanism 40, and a control panel 33. The cleaning mechanism 10 also includes a tube 11, with an inner cavity 12 open on one side. A cleaning valve plate 13 is slidably connected inside the inner cavity 12. An air bag 15 is fixedly installed between the cleaning valve plate 13 and the inner wall of the inner cavity 12. An air inlet 14 is provided on the upper wall of one side of the tube 11. A pulse mechanism 20 is disposed on the upper surface of the tube 11, including a main housing 21 fixedly installed on the upper surface of the tube 11. An air pump 210 is fixedly installed on the outer wall of the main housing 21. An inlet cavity 22 and a compression cavity 23 are provided inside the main housing 21. The output end of the air pump 210 is connected to the main housing 21. The hose is connected to the inlet chamber 22, and the inlet chamber 22 is interconnected with the extrusion chamber 23. Both ends of the connection between the inlet chamber 22 and the extrusion chamber 23 are provided with protrusions 24. A movable rod 25 is slidably connected between the two protrusions 24. Multiple air passages 28 are opened inside the two protrusions 24. A baffle 211 is fixedly installed on one side of the movable rod 25 inside the extrusion chamber 23. A return spring 29 is fixedly installed between the baffle 211 and the inner wall of the extrusion chamber 23. An air outlet 26 is provided on one side of the inlet chamber 22. One side of the movable rod 25 is slidably connected to the inside of the air outlet 26. A connecting pipe 27 is fixedly installed on the outer wall of the air outlet 26. The end of the connecting pipe 27 away from the air outlet 26 is fixedly connected to the air inlet 14.

[0029] After adopting the above technical solution, by setting a cleaning valve plate 13 and an air bag 15 inside the pipe body 11, and setting a pulse mechanism 20 on the upper wall of the pipe body 11, high-pressure air is pumped into the pulse mechanism 20 through an air pump 210. The high-pressure air is converted into pulse gas by the pulse mechanism 20 and sent into the pipe body 11, thereby inflating the air bag 15 and pushing the cleaning valve plate 13 into the conveying pipe. As the cleaning valve plate 13 moves along the inner wall of the conveying pipe, the cleaning valve plate 13 removes the impurities adhering to the inner wall of the conveying pipe, thereby preventing the conveying pipe from being blocked.

[0030] It should be noted that the pipe body 11 is fixedly installed on one side of the conveying pipe via the flange 17. High-pressure gas is intermittently pumped into the inlet chamber 22 at certain time intervals by the air pump 210. The high-pressure gas entering the inlet chamber 22 contacts the baffle 211 via the boss 24. The baffle 211, affected by the air pressure, drives the movable rod 25 to move to the left along the extrusion chamber 23. During the movement of the movable rod 25, its end moves out of the outlet 26, creating a gap between the movable rod 25 and the outlet 26. The high-pressure gas enters the connecting pipe 27 through this gap. When some air is pumped out, the rebound force of the return spring 29 resets the movable rod 25, thus resealing the outlet 26, thereby converting the air into... Pulsed gas enters the inner cavity 12 through the connecting pipe 27. Due to the high-pressure instantaneous impact force of the pulsed air, the pulsed air entering the inner cavity 12 quickly fills the inflation bag 15, thereby pushing the cleaning valve plate 13 to move towards the inner wall of the conveying pipe. During the process of the cleaning valve plate 13 moving along the inner wall of the conveying pipe, the cleaning valve plate 13 removes the impurities adhering to the inner wall of the conveying pipe. When the cleaning valve plate 13 moves to the maximum distance, the motor 42 drives the rotating shaft 43 to rotate. During the rotation of the rotating shaft 43, the winding roller 44 on its outer wall winds up the traction rope 45, thereby pulling the cleaning valve plate 13 that has entered the conveying pipe back through the traction rope 45. The above operation is repeated to achieve self-cleaning of the inner wall of the conveying pipe.

[0031] In an optional embodiment, the recycling mechanism 40 includes a connecting hole 46 located at the center of the right side of the pipe body 11 and a connecting frame 41 fixedly installed on the right side of the pipe body 11. A rotating shaft 43 is rotatably connected inside the connecting frame 41. A motor 42 is fixedly installed on one side of the connecting frame 41. The output shaft end of the motor 42 is fixedly connected to one side of the rotating shaft 43. A winding roller 44 is fixedly installed on both sides of the rotating shaft 43. A traction rope 45 is provided on the outer wall of the winding roller 44. One end of the traction rope 45 passes through the connecting hole 46 and is fixedly connected to the outer wall of one side of the cleaning valve plate 13. The rotating shaft 43 is driven to rotate by the motor 42. During the rotation of the rotating shaft 43, the winding roller 44 on its outer wall winds up the traction rope 45, thereby pulling the cleaning valve plate 13 that has entered the conveying pipe back through the traction rope 45.

[0032] In an optional embodiment, a sealing ring is fixedly installed inside the connection hole 46. The sealing ring improves the sealing between the connection hole 46 and the traction rope 45 and prevents pulsating air leakage.

[0033] In an optional embodiment, the control mechanism 30 includes a mounting box 31 fixedly mounted on the top of the main housing 21. The mounting box 31 has a mounting cavity 32 inside, and a control panel 33 is fixedly mounted inside the mounting cavity 32. The self-cleaning device 100 is controlled by the control mechanism 30.

[0034] In an optional embodiment, a protective cover 34 is hinged to the upper outer wall of the mounting cavity 32, and the control panel 33 inside the mounting cavity 32 is protected by closing the protective cover 34.

[0035] In an optional embodiment, a friction pad 16 is fixedly installed on the outer wall of the cleaning valve plate 13. By fixing the friction pad 16 on the outer wall of the cleaning valve plate 13, the friction between the cleaning valve plate 13 and the inner wall of the conveying pipe is increased. When the cleaning valve plate 13 moves on the inner wall of the conveying pipe, it can remove stubborn impurities from the inner wall of the conveying pipe.

[0036] In one optional implementation, the control panel 33 is provided with control buttons and a display screen on the outside, and the control panel 33 is provided with a control circuit board and a battery inside. The control panel 33 is electrically connected to the air pump 210 and the motor 42. The air pump 210 and the motor 42 are started and stopped by the control panel 33, thereby realizing automatic cleaning and automatic recycling.

[0037] In an optional embodiment, a flange 17 is integrally provided on the side of the pipe body 11 away from the recycling mechanism 40, and a support leg is integrally provided at the bottom of the pipe body 11. The pipe body 11 is connected to the conveying pipe through the flange 17, and the support leg supports the pipe body 11.
