Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and more specifically, to a planetary cylinder cleaning machine. Background Art

[0002] The pull cylinder has a simple structure and is convenient for loading and handling materials. It is used in the production process of chemical materials such as coatings, fuels, pigments, paints, inks, adhesives, etc. It is mainly used with dispersers, grinders, emulsifiers and other machines. When using a pull cylinder, it is often necessary to quickly clean it due to the change of varieties, but usually manual direct cleaning of the pull cylinder is easy to be affected by harmful substances remaining in the pull cylinder and affect health. At the same time, manual cleaning is not only time-consuming but also not clean enough. Many small details are easy to be overlooked, which is easy to affect the quality of the replaced product. For a high pull cylinder, it is difficult to clean the lower part and bottom of the pull cylinder manually.

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

[0004] The present invention overcomes the shortcomings of existing cylinder cleaning machines, such as complex nozzle structure, small water flow impact force and poor cleaning effect, and provides a planetary cylinder cleaning machine, which can reduce the complexity of the nozzle, reduce the number of water lines and increase the impact force of the water lines through planetary rotation, thereby achieving a good cleaning effect.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: A planetary cylinder cleaning machine comprises a lifting mechanism, a planetary mechanism, a cleaning mechanism and a recovery mechanism. The planetary mechanism comprises a sun gear, a sun shaft, a planetary gear and a planetary frame. The planetary mechanism is arranged on a fixed frame. The lifting mechanism can independently lift the fixed frame and the cylinder cover through a guide rod. The sun gear is fixedly connected to the fixed frame, the sun shaft is fixedly connected to the planetary frame, the planetary gear is meshed with the sun gear and the planetary frame, the rotation of the sun shaft drives the rotation and revolution of the planetary gear, the planetary shaft of the planetary gear is fixedly connected to a planetary turntable, and the cleaning mechanism and the recovery mechanism are arranged at both ends of the planetary turntable.

[0006] The lifting mechanism can meet the difficulty of cleaning the dead corners of the pull cylinders at different heights. The recovery mechanism can avoid excessive accumulation of waste liquid at the bottom, which cannot achieve the expected cleaning effect. In addition, since the pull cylinder return pipe can touch the bottom, most of the waste liquid can be recovered.

[0007] By lifting the cylinder cover, the cylinder can be well sealed to prevent materials from splashing during the cleaning process.

[0008] The cleaning mechanism and the recovery mechanism in the device are fixedly arranged on the planetary turntable. As the planetary shaft rotates, the planetary frame drives the planetary wheel because the sun wheel is stationary. Therefore, the planetary wheel both rotates and revolves around the sun wheel. The driven planetary shaft fixed to the planetary wheel drives the cleaning mechanism and the recovery mechanism to revolve and rotate. Only a small number of nozzles are required on the cleaning mechanism to fully cover all places during the rotation process. While reducing the complexity of the nozzles, the impact force of the water line is increased to obtain a good cleaning effect.

[0009] When there is a layer of waste water on the surface of the pull cylinder, the impact force of the water line is difficult to act on the wall of the pull cylinder. By setting up a recovery mechanism, waste water can be recovered during the cleaning process, thereby improving the cleaning efficiency and the cleaning effect.

[0010] Preferably, the cleaning mechanism includes a cleaning bar and a nozzle. The cleaning bar is eccentrically and rotatably connected to the planetary turntable. A single-loop rotary joint is provided at the rotational connection position of the cleaning bar and the planetary turntable. The cleaning bar is provided with a built-in liquid hole. The water outlet of the single-loop rotary joint is connected to the liquid hole. The liquid hole extends along the length direction to positions close to both ends and is connected to the nozzle.

[0011] The above characteristics make the cleaning mechanism form a connecting rod, and the cleaning mechanism moves with inertia and adapts to different cylinder volumes.

[0012] Preferably, a limiting roller is provided at the distal position of the cleaning strip. The structure prevents the cleaning strip from hard contact with the side wall of the fish pulling tank.

[0013] Preferably, the limiting roller is made of a flexible material to avoid wear on the inner wall of the pulling cylinder.

[0014] Preferably, the recovery mechanism comprises a recovery pipe, a recovery nozzle is provided at the bottom of the recovery pipe, and a single-loop rotary joint is provided at the top of the recovery pipe.

[0015] Preferably, an external multi-circuit rotary joint and an internal multi-circuit rotary joint are provided at both ends of the sun shaft, a fluid path connecting the external multi-circuit rotary joint and the internal multi-circuit rotary joint is provided in the shaft body of the sun shaft, a planetary multi-circuit rotary joint is mounted on the planetary shaft, the outlet of the internal multi-circuit rotary joint is connected to the planetary multi-circuit rotary joint through a hose, and the outlet of the planetary multi-circuit rotary joint is connected to the inlet of the single-circuit rotary joint through a hose.

[0016] Liquid passages for the cleaning liquid and the recovery liquid are formed by the structure.

[0017] Preferably, a bottom-probing rod is provided outside the recovery pipe, and the bottom-probing rod is connected to the planetary turntable through an elastic member, and a pressure sensor is provided on the planetary turntable, and the elastic member abuts against the pressure sensor. The structure cooperates with the aforementioned lifting mechanism to control the lifting amplitude. When the bottom-probing rod reaches the bottom, the pressure sensor is pressurized and transmits an electrical signal to the controller to control the lifting mechanism to stop.

[0018] Preferably, the planetary shaft and the sun shaft are provided with a rotatably connected slip ring, and the pressure sensor enters the planetary shaft through the lead from the slip ring outside the planetary shaft, and enters the fixed frame through the slip ring outside the sun shaft to extend out of the cleaning machine to connect to the external controller. The slip ring is rotatably connected to the planetary shaft and the sun shaft to prevent the wire from being entangled on the planetary shaft or the sun shaft.

[0019] As a preferred embodiment, a limit switch is provided on the guide rod, and the limit switch limits the movement stroke of the fixing bracket.

[0020] Compared with the prior art, the present invention has the following beneficial effects: (1) Through the planetary mechanism, a smaller number of nozzles can cover the entire pull cylinder. Fewer nozzles have stronger impact force and better cleaning effect; (2) The inertia-driven structure of the limit roller and the cleaning strip enables the device to adapt to different sizes of pull cylinders and avoid scratching the inner wall of the pull cylinder; (3) The lifting mechanism can seal the pull cylinder and achieve a good sealing effect on pull cylinders of different diameters and heights to prevent material splashing during cleaning. It can also meet the difficulty of cleaning dead corners of pull cylinders of different heights and avoid excessive accumulation of waste liquid in the lower part, which may prevent the expected cleaning effect from being achieved. (3) The bottom probe and pressure sensor make it possible to recover most of the waste liquid and prevent the equipment from hitting the bottom of the cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example: A planetary cylinder cleaning machine, Figure 1 As shown, it includes a lifting mechanism, a planetary mechanism, a cleaning mechanism and a recovery mechanism.

[0028] The lifting mechanism can independently lift the fixed frame 14 and the cylinder cover 15 through the guide rod 13. The lifting mechanism includes a fixed frame cylinder 11, a cylinder cover cylinder 12 and a guide rod 13. The telescopic end of the cylinder cover cylinder 12 is fixedly connected to the cylinder cover 15. The cylinder cover 15 is mounted on the guide rod 13, and the guide rod 13 is arranged along the height direction. The telescopic end of the fixed frame cylinder 11 is fixedly connected to the fixed frame 14. The fixed frame 14 is mounted on the guide rod 13. The guide rod 13 is arranged along the height direction. Among them, the guide rods 13 corresponding to the fixed frame 14 and the cylinder cover 15 are two independent ones. In some embodiments, a limit switch is provided on the guide rod 13, and the limit switch limits the movement stroke of the fixed frame 14 in the rising direction.

[0029] The planetary mechanism includes a sun gear 21, a sun shaft 22, a planetary gear 23 and a planetary carrier 24. The planetary mechanism is arranged 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 planetary carrier 24. The planetary gear 23 is meshed with the sun gear 21 and the planetary carrier 24. The rotation of the sun shaft 22 drives the planetary gear 23 to rotate and revolve.

[0030] The sun gear 21 is dumbbell-shaped, with one end fixedly connected to the fixed frame 14 and the other end meshing with the planetary gear 23. The sun shaft 22 is coaxially arranged with the sun gear 21 and slidingly matched. 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 through a bearing. The lower part of the sun shaft 22 is connected to the planetary carrier 24 through a key to transmit torque. The inner side of the planetary carrier 24 has a gear ring, and the planetary carrier 24 meshes with the planetary gear 23. The planetary carrier 24 is rotatably connected with a planetary shaft 25 through a bearing, and the planetary shaft 25 and the planetary gear 23 are concentric and fixedly connected.

[0031] Since the sun gear 21 is stationary, the planet carrier 24 drives the planet gear 23, so the planet gear 23 both rotates and revolves around the sun gear 21. The driven planet shaft 25 fixed to the planet gear 23 drives the cleaning mechanism and the recovery mechanism to revolve and rotate.

[0032] The planetary shaft 25 of the planetary wheel 23 is fixedly connected to a planetary turntable 26, and a cleaning mechanism and a recovery mechanism are arranged at both ends of the planetary turntable 26. The planetary shaft 25 is connected to an eccentric position of the planetary turntable 26. The planetary turntable 26 rotates co-rotatingly and rotating with the planetary shaft 25. The planetary shaft 25 is connected to an eccentric position of the planetary turntable 26. A cleaning mechanism is arranged at the proximal end of the planetary turntable 26, and a recovery mechanism is arranged at the distal end.

[0033] The cleaning mechanism includes a cleaning bar 31 and a nozzle 34. The cleaning bar 31 is eccentrically and rotationally connected to the planetary turntable 26. A single-circuit rotary joint is sleeved outside the connecting shaft of the cleaning bar 31 and the planetary turntable 26. The cleaning bar 31 is provided with a built-in liquid hole 33. The water outlet of the single-circuit rotary joint is connected to the liquid hole 33. The liquid hole 33 extends along the length direction to positions close to both ends and is connected to the nozzle 34.

[0034] Ginseng Figure 2 As shown, the cleaning strip 31 is rotatably connected to the planetary turntable 26, so the cleaning strip 31 rotates under inertia. This structure and the aforementioned planetary mechanism form a connecting rod, which can fully cover as many areas as possible and adapt to different cylinder volumes. Since the cleaning strip 31 is rotatably connected, it is set at the proximal end of the planetary turntable 26, so that the probability of the cleaning strip 31 rotating is greater and avoids the recovery mechanism at the distal end.

[0035] A limiting roller 35 is provided at the distal position of the cleaning strip 31. The structure prevents the cleaning strip 31 from hard contact with the side wall of the pull cylinder. The limiting roller 35 is made of a flexible material to avoid wear on the inner wall of the pull cylinder.

[0036] The recovery mechanism comprises a recovery pipe 41 , a recovery nozzle 42 is provided at the bottom of the recovery pipe 41 , and a single-circuit rotary joint is provided at the top of the recovery pipe 41 . The recovery pipe 41 is fixedly connected to the planetary turntable 26 .

[0037] A bottom-probing rod 43 is provided outside the recovery tube 41, and the bottom-probing 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, and the elastic member 44 abuts against the pressure sensor 45. The structure cooperates with the aforementioned lifting mechanism to control the lifting amplitude. When the bottom-probing rod 43 reaches the bottom, the pressure sensor 45 is pressurized, and an electrical signal is transmitted to the controller to control the lifting mechanism to stop. Specifically, a shell 46 is provided on the planetary turntable 26, and the bottom-probing tube and the elastic member 44 are arranged in the shell 46, and the shell 46 constrains the elastic member 44. When the bottom-probing tube is pressurized, 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 descending stroke of the cleaning machine through the controller.

[0038] The liquid circuit of the whole device is as follows: An external multi-circuit rotary joint 51 and an internal multi-circuit rotary joint 52 are provided at both ends of the sun shaft 22. The external water inlet and return pipes are connected to the external multi-circuit rotary head. A fluid path connecting the external multi-circuit rotary joint 51 and the internal multi-circuit rotary joint 52 is provided in the shaft body of the sun shaft 22. Through this structure, the inlet and return water are introduced to the bottom of the pull cylinder. A planetary multi-circuit rotary joint 53 is mounted on the planetary shaft 25, and the outlet of the internal multi-circuit rotary joint 52 is connected to the inlet of the planetary multi-circuit rotary joint 53 through a hose. Since both the planetary shaft 25 and the sun shaft 22 rotate, the only movement of the planetary shaft 25 relative to the sun shaft 22 is self-rotation, and since the planetary multi-circuit rotary joint 53 can rotate relative to the planetary shaft 25, it is possible to avoid the hose being wrapped around the planetary shaft 25.

[0039] The outlet of the planetary multi-circuit rotary joint 53 is connected to the inlet of the single-circuit rotary joint through a hose. The single-circuit rotary joint includes a cleaning single-circuit rotary joint 32 of the cleaning mechanism and a recovery single-circuit rotary joint 47 of the recovery mechanism.

[0040] The planetary multi-circuit rotary joint 53 can remain relatively still with the cleaning single-circuit rotary joint 32 and the recovery single-circuit rotary joint 47, so the hose will not get entangled.

[0041] The aforementioned pressure sensor 45 also needs to transmit the electrical signal to the controller outside the cleaning machine through the wiring harness. The planetary shaft 25 and the sun shaft 22 are provided with a rotatably connected slip ring 6. The pressure sensor 45 enters the planetary shaft 25 through the lead from the slip ring 6 outside the planetary shaft 25, and enters the fixed frame 14 through the slip ring 6 outside the sun shaft 22 to extend out of the cleaning machine to connect to the external controller. The slip ring 6 is rotatably connected to the planetary shaft 25 and the sun shaft 22 to prevent the wire from being entangled on the planetary shaft 25 or the sun shaft 22.

[0042] The lifting mechanism can meet the difficulty of cleaning the dead corners of the pull cylinders at different heights. The recovery mechanism can avoid excessive accumulation of waste liquid at the bottom, which cannot achieve the expected cleaning effect. In addition, since the pull cylinder return pipe can touch the bottom, most of the waste liquid can be recovered.

[0043] By lifting and lowering the pull cylinder cover 15, the pull cylinder can be well sealed to prevent the material from splashing out during the cleaning process.

[0044] The cleaning mechanism and the recovery mechanism in the device are fixedly arranged on the planetary turntable 26 and rotate with the planetary shaft 25. Only a small number of nozzles are required on the cleaning mechanism to fully cover all places during the rotation process, thereby reducing the complexity of the nozzles and increasing the impact force of the water line to obtain a good cleaning effect.

[0045] When there is a layer of waste water on the surface of the pull cylinder, the impact force of the water line is difficult to act on the wall of the pull cylinder. By setting up a recovery mechanism, waste water can be recovered during the cleaning process, thereby improving the cleaning efficiency and the cleaning effect.
