Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and more specifically, to a planetary cylinder cleaning machine. Background Technology

[0002] Cylinder separators have a simple structure, facilitating material loading and handling. They are used in the production of chemical materials such as coatings, fuels, pigments, paints, inks, and adhesives. They are primarily used in conjunction with machinery such as dispersers, grinders, and emulsifiers. When using cylinder separators, rapid cleaning is often required due to product changes. However, manual cleaning of cylinder separators can easily lead to health risks from residual harmful substances. Furthermore, manual cleaning is time-consuming and often lacks thoroughness, easily overlooking small details and potentially affecting the quality of the replaced product. For tall cylinder separators, manual cleaning often fails to reach the lower and bottom parts.

[0003] Existing cylinder cleaning machines mostly use a rotary system for cleaning, and the nozzles need to be arranged in a comb shape. As the nozzles rotate along the axis of the cylinder, the water jets sprayed from the nozzles cover the cylinder. However, this type of nozzle design is relatively complex. Due to the large number of water jets, the impact force of a single water jet is weak, making it difficult to remove stubborn dirt. Summary of the Invention

[0004] This invention overcomes the shortcomings of existing cylinder cleaning machines, such as complex nozzle structure, low water flow impact force, and poor cleaning effect. It provides a planetary cylinder cleaning machine that reduces nozzle complexity, reduces the number of water lines, and increases water flow impact force through planetary rotation, thereby achieving a good cleaning effect.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A planetary cylinder cleaning machine includes a lifting mechanism, a planetary mechanism, a cleaning mechanism, and a recycling mechanism. The planetary mechanism includes a sun gear, a sun shaft, planet gears, and a planet carrier. The planetary mechanism is mounted on a fixed frame. The lifting mechanism can independently lift the fixed frame and the cylinder head via a guide rod. The sun gear is fixedly connected to the fixed frame, and the sun shaft is fixedly connected to the planet carrier. The planet gears mesh with the sun gear and the planet carrier. The rotation of the sun shaft drives the rotation and revolution of the planet gears. The planet shafts of the planet gears are fixedly connected to planetary disks. The cleaning mechanism and the recycling mechanism are located at both ends of the planetary disks.

[0007] The lifting mechanism addresses the challenge of cleaning hard-to-reach areas during cylinder cleaning at different heights. The recovery mechanism prevents excessive waste liquid accumulation at the bottom, ensuring optimal cleaning results. Furthermore, the cylinder return pipe's ability to reach the bottom allows for the recovery of most of the waste liquid.

[0008] By raising and lowering the cylinder cover, the cylinder can be effectively sealed, preventing material from splashing out during the cleaning process.

[0009] In this device, both the cleaning and recovery mechanisms are fixedly mounted on a planetary rotor. As the planetary shaft rotates, the sun gear remains stationary while the planetary carrier drives the planetary gears. Therefore, the planetary gears both rotate on their own axes and revolve around the sun gear. The driven planetary shaft, fixed to the planetary gears, drives both the cleaning and recovery mechanisms in their rotation and revolution. The cleaning mechanism requires only a small number of nozzles to effectively cover all areas during rotation, reducing nozzle complexity while increasing the impact force of the water stream and achieving excellent cleaning results.

[0010] When there is a layer of wastewater on the surface of the cylinder, the impact force of the water line is difficult to act on the cylinder wall. By setting up a recycling mechanism, the wastewater can be recycled at the same time during the cleaning process, which improves the cleaning efficiency and cleaning effect.

[0011] Preferably, the cleaning mechanism includes a cleaning strip and a nozzle. The cleaning strip is eccentrically and rotatably connected to the planetary turntable. A single-loop rotary joint is provided at the rotatable connection position between the cleaning strip and the planetary turntable. The cleaning strip is provided with a built-in liquid passage hole. The outlet of the single-loop rotary joint is connected to the liquid passage hole. The liquid passage hole extends along the length direction to a position near both ends and connects to the nozzle.

[0012] These features enable the cleaning mechanism to form a linkage, allowing it to move with inertia and adapt to different cylinder volumes.

[0013] Preferably, a limiting roller is provided at the distal position of the cleaning strip. This structure prevents the cleaning strip from making hard contact with the side wall of the tank.

[0014] Preferably, the limiting roller is made of a flexible material to avoid wear on the inner wall of the cylinder.

[0015] Preferably, the recycling mechanism includes a recycling pipe with a recycling nozzle at the bottom and a single-loop rotary joint at the top.

[0016] Preferably, the sun shaft is provided with an external multi-loop rotary joint and an internal multi-loop rotary joint at both ends. The shaft body of the sun shaft is provided with a fluid passage connecting the external multi-loop rotary joint and the internal multi-loop rotary joint. The planetary shaft is fitted with a planetary multi-loop rotary joint. The outlet of the internal multi-loop rotary joint is connected to the planetary multi-loop rotary joint through a hose. The outlet of the planetary multi-loop rotary joint is connected to the inlet of the single-loop rotary joint through a hose.

[0017] The structure forms a liquid passage for cleaning fluid and recovery fluid.

[0018] Preferably, a bottom probe is installed outside the recovery pipe. The bottom probe is connected to a planetary rotor via an elastic element. A pressure sensor is installed on the planetary rotor, and the elastic element abuts against the pressure sensor. This structure, in conjunction with the aforementioned lifting mechanism, controls the lifting range. When the bottom probe reaches the bottom, the pressure sensor is compressed, transmitting an electrical signal to the controller to stop the lifting mechanism.

[0019] Preferably, the planetary shaft and sun shaft are provided with rotatably connected slip rings. The pressure sensor enters the planetary shaft through the slip ring outside the planetary shaft via a lead wire, and then enters the fixed frame through the slip ring outside the sun shaft to extend out of the cleaning machine and connect to an external controller. The slip rings are rotatably connected to the planetary shaft and sun shaft, preventing the wires from getting tangled on the planetary shaft or sun shaft.

[0020] As a preferred option, the guide rod is equipped with a limit switch, which limits the movement stroke of the fixing frame.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) Through the planetary mechanism, the entire cylinder is covered with a smaller number of nozzles. Fewer nozzles have a stronger impact force and a better cleaning effect.

[0023] (2) The inertial drive structure of the limiting roller and cleaning strip enables the device to adapt to cylinders of different sizes and avoid scratches on the inner wall of the cylinder;

[0024] (3) The lifting mechanism can seal the cylinder and achieve a good sealing effect for cylinders of different diameters and heights, preventing material from splashing during cleaning. It can also address the difficulty of cleaning dead corners in cylinders of different heights and avoid excessive accumulation of waste liquid at the bottom, thus preventing the desired cleaning effect from being achieved.

[0025] (3) The bottom probe and pressure sensor enable the recovery of most of the waste liquid while avoiding the equipment from hitting the bottom of the cylinder. Attached Figure Description

[0035] Example:

[0036] A planetary cylinder cleaning machine, reference Figure 1 As shown, it includes a lifting mechanism, a planetary mechanism, a cleaning mechanism, and a recycling mechanism.

[0037] The lifting mechanism can independently raise and lower the fixed frame 14 and the cylinder head 15 via the guide rod 13. The lifting mechanism includes a fixed frame cylinder 11, a cylinder head cylinder 12, and a guide rod 13. The telescopic end of the cylinder head cylinder 12 is fixedly connected to the cylinder head 15, which is mounted on the guide rod 13, which is positioned along the height direction. The telescopic end of the fixed frame cylinder 11 is fixedly connected to the fixed frame 14, which is mounted on the guide rod 13, which is positioned along the height direction. The guide rods 13 corresponding to the fixed frame 14 and the cylinder head 15 are two independent rods. In some embodiments, a limit switch is provided on the guide rod 13 to limit the upward movement of the fixed frame 14.

[0038] The planetary mechanism includes a sun gear 21, a sun shaft 22, planet gears 23, and a planet carrier 24. The planetary mechanism is mounted on a fixed frame 14. The sun gear 21 is fixedly connected to the fixed frame 14, the sun shaft 22 is fixedly connected to the planet carrier 24, and the planet gears 23 mesh with the sun gear 21 and the planet carrier 24. The rotation of the sun shaft 22 drives the rotation and revolution of the planet gears 23.

[0039] The sun gear 21 is dumbbell-shaped, with one end fixedly connected to the fixed frame 14 and the other end meshing with the planet gear 23. The sun shaft 22 is coaxially arranged and slidingly fitted with the sun gear 21. The upper part of the sun shaft 22 is connected to an external power source. The fixed frame 14 and the sun shaft 22 are rotatably connected by bearings. The lower part of the sun shaft 22 is connected to the planet carrier 24 by a key to transmit torque. The inner surface of the planet carrier 24 has a gear ring, which meshes with the planet gear 23. The planet carrier 24 is rotatably connected to the planet shaft 25 by bearings, and the planet shaft 25 and the planet gear 23 are concentric and fixedly connected.

[0040] Since the sun gear 21 is stationary, the planet carrier 24 drives the planet gears 23. Therefore, the planet gears 23 both rotate on their own axis and revolve around the sun gear 21. The planetary shafts 25, which are fixed to the planet gears 23 and are driven, drive the cleaning mechanism and the recycling mechanism to revolve and rotate.

[0041] The planetary gear 23 has a planetary shaft 25 fixedly connected to a planetary disk 26. A cleaning mechanism and a recycling mechanism are located at both ends of the planetary disk 26. The planetary shaft 25 is connected to an eccentric position on the planetary disk 26. The planetary disk 26 rotates and revolves around the planetary shaft 25. The planetary shaft 25 is connected to an eccentric position on the planetary disk 26. A cleaning mechanism is located at the proximal end of the planetary disk 26, and a recycling mechanism is located at the distal end.

[0042] The cleaning mechanism includes a cleaning strip 31 and a nozzle 34. The cleaning strip 31 is eccentrically and rotationally connected to the planetary turntable 26. A single-loop rotary joint is sleeved outside the connecting shaft of the cleaning strip 31 and the planetary turntable 26. The cleaning strip 31 is provided with an internal liquid passing hole 33. The water outlet of the single-loop rotary joint is connected to the liquid passing hole 33. The liquid passing hole 33 extends along the length direction to positions near both ends and is connected to the nozzle 34.

[0043] As Figure 2 shown, since the cleaning strip 31 is rotationally connected to the planetary turntable 26, the cleaning strip 31 rotates under inertia. This structure and the foregoing planetary mechanism form a connecting rod, which can fully cover as many areas as possible and adapt to different cylinder honing volumes. Since the cleaning strip 31 is rotationally connected, it is arranged at the proximal end of the planetary turntable 26, making the cleaning strip 31 more likely to rotate and avoiding the recovery mechanism at the distal end.

[0044] A limit roller 35 is provided at the distal position of the cleaning strip 31. This structure prevents the cleaning strip 31 from making hard contact with the side wall of the cylinder honing. Among them, the limit roller 35 is made of a flexible material to avoid abrasion of the inner wall of the cylinder honing.

[0045] The recovery mechanism includes a recovery pipe 41. A recovery nozzle 42 is provided at the bottom of the recovery pipe 41. A single-loop rotary joint is provided at the top of the recovery pipe 41. The recovery pipe 41 is fixedly connected to the planetary turntable 26.

[0046] A bottom detection rod 43 is provided outside the recovery pipe 41. The bottom detection rod 43 is connected to the planetary turntable 26 through an elastic member 44. A pressure sensor 45 is provided on the planetary turntable 26. The elastic member 44 abuts against the pressure sensor 45. This structure cooperates with the foregoing lifting mechanism to control the lifting amplitude. When the bottom detection rod 43 reaches the bottom, the pressure sensor 45 is pressed, and an electrical signal is transmitted to the controller to control the lifting mechanism to stop. Specifically, a housing 46 is provided on the planetary turntable 26. The bottom detection pipe and the elastic member 44 are arranged in the housing 46. The housing 46 restricts the elastic member 44. When the bottom detection pipe is pressed, the elastic member 44 is compressed, and the elastic member 44 can transfer the corresponding pressure to the pressure sensor 45, thereby obtaining a corresponding electrical signal and controlling the downward stroke of the honing machine through the controller.

[0047] The liquid path of the entire device is as follows:

[0048] The sun shaft 22 has an external multi-loop rotary joint 51 and an internal multi-loop rotary joint 52 at both ends. External inlet and return water pipes are connected to the external multi-loop rotary head. The shaft of the sun shaft 22 has a fluid passage connecting the external multi-loop rotary joint 51 and the internal multi-loop rotary joint 52. This structure allows inlet and return water to be introduced near the bottom of the cylinder. A planetary multi-loop rotary joint 53 is fitted onto the planetary shaft 25, and the outlet of the internal multi-loop rotary joint 52 is connected to the inlet of the planetary multi-loop rotary joint 53 via a flexible hose. Since both the planetary shaft 25 and the sun shaft 22 rotate, the movement of the planetary shaft 25 relative to the sun shaft 22 is only its own rotation. Furthermore, because the planetary multi-loop rotary joint 53 can rotate relative to the planetary shaft 25, the flexible hose can be prevented from wrapping around the planetary shaft 25.

[0049] The outlet of the planetary multi-loop rotary joint 53 is connected to the inlet of the single-loop rotary joint via a hose. The single-loop rotary joint includes a cleaning single-loop rotary joint 32 for the cleaning mechanism and a recycling single-loop rotary joint 47 for the recycling mechanism.

[0050] The planetary multi-circuit rotary joint 53 can remain relatively stationary with the cleaning single-circuit rotary joint 32 and the recycling single-circuit rotary joint 47, so the hose will not get tangled.

[0051] The aforementioned pressure sensor 45 also needs to transmit electrical signals to an external controller via a wiring harness. A slip ring 6 is rotatably connected to the planetary shaft 25 and the sun shaft 22. The pressure sensor 45 enters the planetary shaft 25 via a lead wire from the slip ring 6 outside the planetary shaft 25, and then enters the mounting bracket 14 via the slip ring 6 outside the sun shaft 22 to extend out of the cleaning machine and connect to the external controller. The slip ring 6 is rotatably connected to the planetary shaft 25 and the sun shaft 22, preventing the wires from getting tangled on the planetary shaft 25 or the sun shaft 22.

[0052] The lifting mechanism addresses the challenge of cleaning hard-to-reach areas during cylinder cleaning at different heights. The recovery mechanism prevents excessive waste liquid accumulation at the bottom, ensuring optimal cleaning results. Furthermore, the cylinder return pipe's ability to reach the bottom allows for the recovery of most of the waste liquid.

[0053] By raising and lowering the cylinder cover 15, the cylinder can be effectively sealed, preventing material from splashing out during the cleaning process.

[0054] Both the cleaning and recovery mechanisms in this device are fixedly mounted on the planetary turntable 26, rotating with the planetary shaft 25. The cleaning mechanism requires only a small number of nozzles to fully cover all areas during rotation, reducing nozzle complexity while increasing the impact force of the water stream and achieving excellent cleaning results.

[0055] When there is a layer of wastewater on the surface of the cylinder, the impact force of the water line is difficult to act on the cylinder wall. By setting up a recycling mechanism, the wastewater can be recycled at the same time during the cleaning process, which improves the cleaning efficiency and cleaning effect.

[0056] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications may be made without departing from the technical solutions described in the claims.
