Description

Technical Field

[0001] This utility model belongs to the technical field of industrial cleaning equipment, specifically relating to a water-based cleaning device. Background Technology

[0002] Water-based cleaning agents are widely used in factories to clean various oil stains, dirt, and grease from the surfaces of machined products. Water-based cleaning agents have the following advantages: strong cleaning power, no damage to the workpiece, and no corrosion; safe to use, environmentally friendly, and the waste liquid can be directly discharged after neutralization without polluting the environment; unlike solvents such as trichloroethylene, chloroform, and Freon, they do not cause ozone layer depletion or harm to the health of workers due to the volatilization of organic solvents.

[0003] Chinese utility model CN ​​221288300 U discloses a water-based cleaning fluid uniform spraying device. In the production of large metal parts, a motor drives two lead screws on the front of a support frame to rotate synchronously. These rotating lead screws then drive a connecting block to move synchronously, causing the hose to rise or fall smoothly. Under the action of a cylinder, a piston forces the water-based cleaning fluid onto the nozzle of the hose, allowing for rapid and uniform spraying of the cleaning fluid for cleaning large metal parts. However, this device struggles to ensure uniform cleaning of different sides or circumferences of metal workpieces produced using rotary machining, such as nuts, bolts, or hubs, when spraying the water-based cleaning agent. Utility Model Content

[0004] The purpose of this invention is to provide a water-based cleaning device to solve the problem mentioned in the background art that existing cleaning devices are difficult to ensure uniform cleaning of different sides or circumferences of metal workpieces produced by rotary machining when spraying water-based cleaning agents.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A water-based cleaning device includes a cleaning tank and a drive mechanism. The cleaning tank is provided with an inlet and an outlet, and the drive mechanism is installed on the cleaning tank.

[0007] A swing-type cleaning mechanism is installed in the cleaning tank from the inlet to the outlet. A lifting rod is connected to one end of the swing-type cleaning mechanism near the inlet, and the top of the lifting rod is fixedly connected to the cleaning tank. The lifting rod is used to adjust the tilt of the swing-type cleaning mechanism.

[0008] The cleaning tank is equipped with an output mechanism at the discharge port. One end of the output mechanism, which is close to the swing cleaning mechanism, extends downward at an angle to the bottom of the swing cleaning mechanism, and the other end of the output mechanism extends to the discharge port.

[0009] The drive mechanism is connected to the swing cleaning mechanism and the output mechanism for driving the swing cleaning mechanism to swing the metal workpiece, and driving the output mechanism to output the metal workpiece cleaned by the swing cleaning mechanism from the discharge port.

[0010] With the above structure, a water-based cleaning agent can be added to the cleaning tank, along with an appropriate proportion of water. Processed metal workpieces (e.g., copper nuts, bolts, alloy discs, etc.) can be placed in the cleaning tank for immersion cleaning; the water-based cleaning agent completely submerges the metal workpieces. The oscillating cleaning mechanism operates, performing an oscillating cleaning motion on the metal workpieces; this allows the water-based cleaning agent to thoroughly rinse all surfaces of the metal workpieces, achieving uniform cleaning. Afterwards, the lifting rod raises one end of the oscillating cleaning mechanism, causing the metal workpieces to fall into the output mechanism, which then transports them to the discharge port for output.

[0011] Furthermore, the swing-type cleaning mechanism includes a chain mesh belt and a crankshaft. The two ends of the chain mesh belt are slidably installed in the cleaning tank, and the end of the chain mesh belt near the feed inlet is fixedly connected to a lifting rod. The crankshaft is rotatably installed in the cleaning tank from the feed inlet to the discharge outlet. The crankshaft is located below the chain mesh belt, and several cams are periodically linearly arrayed on the crankshaft. During rotation, the cams periodically contact the lower surface of the chain mesh belt, and the end of the crankshaft is connected to the drive mechanism for transmission.

[0012] Through the above structure, the chain mesh belt cooperates with several cams on the crankshaft to make the chain mesh belt undulate periodically from the feed port to the discharge port, thereby achieving oscillating cleaning of metal workpieces; furthermore, if the chain mesh belt is needed to transport metal workpieces, it is only necessary to raise the lifting rod, which is simple to operate, versatile and highly practical.

[0013] Furthermore, a guide groove is provided on the inner wall of the cleaning tank near the feed inlet, and a limiting groove is provided on the inner wall of the cleaning tank near the bottom of the output mechanism; one end of the chain mesh belt is rotatably connected to a first connecting shaft, which is slidably installed in the guide groove, and the other end of the chain mesh belt is rotatably connected to a second connecting shaft, which is slidably installed in the limiting groove; the highest point of the guide groove is higher than the highest point of the limiting groove.

[0014] The above structure can relatively limit the ends of the chain conveyor belt, preventing metal workpieces from falling into the bottom of the cleaning tank.

[0015] Furthermore, the number of crankshafts is set to two, and the two crankshafts are rotatably installed in the cleaning tank in opposite directions. One of the crankshafts is connected to the drive mechanism through a universal joint, and the two crankshafts are connected by a synchronous belt.

[0016] With the above structure, the two crankshafts are installed in the cleaning tank with relative rotation, providing uniform support to the front and rear bottom surfaces of the chain belt, making the support and drive more stable.

[0017] Furthermore, the cleaning tank is provided with a drying chamber at the outlet; a heating element is provided in the drying chamber, which is used to dry the metal workpieces passing through the outlet.

[0018] The above structure allows for the drying of metal workpieces output by the output mechanism, making subsequent storage more convenient and reliable.

[0019] Furthermore, an air nozzle is installed on the side of the drying chamber near the feed inlet, and the air jet direction of the air nozzle is close to the tilt direction of the output mechanism.

[0020] With the above structure, on the one hand, the jet nozzle can assist the output mechanism in draining the metal workpiece and improve the conveying efficiency; on the other hand, it can blow away the floating objects on the surface of the water-based cleaning agent, preventing the floating objects from being carried out by the output mechanism and affecting the drying effect of the metal workpiece.

[0021] Furthermore, the output mechanism includes a mounting frame and a conveyor belt. The mounting frame is fixedly installed inside the cleaning tank, and the conveyor belt is mounted on the mounting frame via several rotating shafts. The end of the conveyor belt near the chain mesh belt extends downward at an angle to below the chain mesh belt.

[0022] Furthermore, the drive mechanism includes a servo motor, a drive wheel, a conveyor belt drive wheel, a crankshaft drive wheel, and a drive belt. The servo motor is fixedly mounted on the cleaning tank, the drive wheel is mounted on the output shaft of the servo motor, and the conveyor belt drive wheel is mounted on one of the rotating shafts. An intermediate shaft is rotatably mounted on the cleaning tank. The crankshaft drive wheel is mounted on the outer end of the intermediate shaft, and the inner end of the intermediate shaft is connected to the crankshaft for transmission. The drive belt connects the drive wheel, the conveyor belt drive wheel, and the crankshaft drive wheel.

[0023] The feed inlet can be equipped with a conveyor belt for inputting metal workpieces for automatic input; it can also work in conjunction with the output mechanism for more automated cleaning.

[0024] The utility model adopting the above technical solution has the following advantages:

[0025] In this application, when cleaning metal workpieces, a water-based cleaning agent is first added to soak and clean the metal workpieces; the water-based cleaning agent completely submerges the metal workpieces. The crankshaft of the swing-type cleaning mechanism rotates, making periodic contact with various parts of the chain mesh belt, causing the chain mesh belt to undulate or swing, performing swing-type cleaning on the metal workpieces; this allows the water-based cleaning agent to thoroughly rinse all surfaces of the metal workpieces, achieving uniform cleaning; afterwards, the lifting rod pulls up one end of the chain mesh belt, causing the metal workpieces to fall onto the conveyor belt of the output mechanism, and then the metal workpieces are transported to the discharge port for output;

[0026] When the lifting rod pulls up one end of the chain mesh belt, starting from the feed port end, the chain mesh belt gradually disengages from the cam on the crankshaft, and the metal workpiece on the chain mesh belt will be transferred to the conveyor belt; in this way, through the cooperation of the chain mesh belt, crankshaft and cam, the swing-type cleaning and conveying of the metal workpiece is realized.

[0027] During the conveyor belt transport of metal workpieces, the metal workpieces are first drained, and then dried in conjunction with the heating element before being output. The structure is simple and highly practical. The servo motor can synchronously drive the crankshaft and the conveyor belt, resulting in high power utilization and ensuring high energy efficiency.

[0040] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0041] like Figures 1 to 6 As shown, in one embodiment, a water-based cleaning device includes a cleaning tank 1 and a drive mechanism 4. The cleaning tank 1 is provided with an inlet 11 and an outlet 18, so as to... Figure 3For example, the inlet 11 is located at the left end of the cleaning tank 1, and the outlet 18 is located at the right end of the cleaning tank 1; a mounting plate 12 is fixed to the top of the left end of the cleaning tank 1. The drive mechanism 4 is installed on the cleaning tank 1; a swing cleaning mechanism 2 is installed in the cleaning tank 1 from the inlet 11 to the outlet 18. A lifting rod 22 is connected to one end of the swing cleaning mechanism 2 near the inlet 11, and the top of the lifting rod 22 is fixedly connected to the cleaning tank 1; the lifting rod 22 is used to adjust the tilt of the swing cleaning mechanism 2. An output mechanism 3 is installed at the outlet 18 of the cleaning tank 1. One end of the output mechanism 3 near the swing cleaning mechanism 2 extends downward at an angle to the bottom of the swing cleaning mechanism 2, and the other end of the output mechanism 3 extends to the outlet 18; the drive mechanism 4 is connected to the swing cleaning mechanism 2 and the output mechanism 3 for driving the swing cleaning mechanism 2 to swing the metal workpiece, and driving the output mechanism 3 to output the metal workpiece cleaned by the swing cleaning mechanism 2 from the outlet 18. The lifting rod 22 adjusts the tilt of the swing cleaning mechanism 2, which allows the metal workpiece to be transferred from the swing cleaning mechanism 2 to the output mechanism 3.

[0042] In this embodiment, a water-based cleaning agent is added to the cleaning tank 1, and an appropriate proportion of water can be added. Processed metal workpieces such as nuts, bolts, or screws can be placed in the cleaning tank 1 for soaking and cleaning; the water-based cleaning agent completely submerges the nuts, bolts, etc. The swing-type cleaning mechanism 2 operates, performing a swing-type cleaning of the metal workpieces; this allows the water-based cleaning agent to thoroughly rinse all surfaces of the metal workpieces, achieving uniform cleaning; afterwards, the lifting rod 22 raises one end of the swing-type cleaning mechanism 2, causing the metal workpiece to fall into the output mechanism 3, and then the metal workpiece is conveyed to the discharge port 18 for output.

[0043] In fact, metal workpieces can also be directly poured into the swing-type cleaning mechanism 2 inside the cleaning tank 1.

[0044] In this embodiment, the swing-type cleaning mechanism 2 includes a chain mesh belt 21 and a crankshaft 23. The two ends of the chain mesh belt 21 are slidably installed in the cleaning tank 1, and the end of the chain mesh belt 21 near the feed inlet 11 is fixedly connected to the lifting rod 22. The crankshaft 23 is rotatably installed in the cleaning tank 1 from the feed inlet 11 to the discharge outlet 18. The crankshaft 23 is located below the chain mesh belt 21. Several cams are periodically linearly arrayed on the crankshaft 23. During the rotation of the cams, they periodically contact the lower surface of the chain mesh belt 21. The end of the crankshaft 23 is connected to the drive mechanism 4 for transmission.

[0045] An end plate 15 is fixedly installed on the left inner wall of the cleaning tank 1, and an intermediate plate 17 is fixedly installed in the middle; the two ends of the crankshaft 23 are installed between the end plate 15 and the intermediate plate 17 through bearings.

[0046] During the cleaning of metal workpieces, the chain mesh belt 21, in cooperation with several cams on the crankshaft 23, causes the chain mesh belt 21 to undulate periodically from the inlet 11 to the outlet 18, achieving a swing-style cleaning of the metal workpieces. Furthermore, if the chain mesh belt 21 needs to convey the metal workpieces, simply raise the lifting rod 22. The operation is simple, and the chain mesh belt is versatile and highly practical. In fact, the number of cams can be flexibly selected according to the length of the chain mesh belt 21.

[0047] In this embodiment, a guide groove 24 is provided on the inner wall of the cleaning tank 1 near the feed inlet 11, and a limiting groove 28 is provided on the inner wall of the cleaning tank 1 near the bottom of the output mechanism 3; one end of the chain mesh belt 21 is rotatably connected to a first connecting shaft, and the first connecting shaft 25 is slidably installed in the guide groove 24; the other end of the chain mesh belt 21 is rotatably connected to a second connecting shaft, and the second connecting shaft 27 is slidably installed in the limiting groove 28; the highest point of the guide groove 24 is higher than the highest point of the limiting groove 28, so that after the lifting rod pulls up one end of the chain mesh belt 21, the metal workpiece can fall onto the output mechanism 3 based on gravity.

[0048] In this way, the end of the chain mesh belt 21 can be relatively limited, preventing the metal workpieces of the chain mesh belt 21 from falling into the bottom of the cleaning tank 1.

[0049] In fact, the lifting rod 22 can be a pneumatic rod, and a connecting rod 26 is connected between the pneumatic rod and the first connecting shaft 25. The connection between the connecting rod 26 and the pneumatic rod and the first connecting shaft 25 can be a rotatable connection.

[0050] In fact, there is one crankshaft 23, which is centrally located in the middle of the lower surface of the chain mesh belt 21.

[0051] In this embodiment, two crankshafts 23 are provided. Specifically, the two crankshafts 23 are rotatably mounted in the cleaning tank 1 via end plates 15 and intermediate plates 17. One crankshaft 23 is connected to the drive mechanism 4 via a universal joint, and the two crankshafts 23 are connected by a synchronous belt 29. Thus, the two crankshafts 23, rotatably mounted in the cleaning tank 1, provide uniform support to the front and rear bottom surfaces of the chain mesh belt 21, resulting in more stable support and drive.

[0052] In fact, a 90° universal joint coupling can be selected as needed; this is existing technology and will not be elaborated here.

[0053] In this embodiment, a turbulence bar 16 is fixedly installed on the right side of the intermediate plate 17. The turbulence bar 16 is located between the right end of the chain mesh belt 21 and the bottom of the conveyor belt, which interferes with the water flow between the chain mesh belt 21 and the conveyor belt 31, thereby reducing the mutual influence between the water flow stirred by the chain mesh belt 21 and the conveyor belt 31.

[0054] In this embodiment, a drying chamber 13 is provided at the outlet 18 of the cleaning tank 1; a heating element is provided in the drying chamber 13, which is used to dry the metal workpieces passing through the outlet 18.

[0055] The heating element includes an electric heating tube, which is connected to a battery or AC power. The conveyor belt at the corresponding position in the drying chamber 13 is used as the drying section 32, which can dry the metal workpieces output from the conveyor belt 31, making subsequent storage more convenient and reliable.

[0056] In fact, a power chamber 14 is provided below the drying chamber 13; the power chamber 14 is used to install the drive mechanism 4.

[0057] A jet nozzle 34 is installed on the side of the drying chamber 13 near the feed inlet 11, and the jet direction of the jet nozzle 34 is close to the tilt direction of the output mechanism 3.

[0058] The nozzle 34 is connected to the factory's air supply line, which supplies dry, high-temperature air.

[0059] Thus, the air nozzle 34 can, on the one hand, assist the conveyor belt 31 in draining the metal workpiece and improve the conveying efficiency; on the other hand, it can blow away floating objects on the surface of the water-based cleaning agent, preventing the floating objects from being carried out by the conveyor belt 31 and affecting the drying effect of the metal workpiece.

[0060] In this embodiment, the output mechanism 3 includes a mounting frame 33 and a conveyor belt 31. The mounting frame 33 is fixedly installed in the cleaning tank 1, and the conveyor belt 31 is mounted on the mounting frame 33 through several rotating shafts. The end of the conveyor belt 31 near the chain mesh belt 21 extends downward at an angle to the bottom of the chain mesh belt 21.

[0061] Several rotating shafts are installed in the cleaning tank 1 in a specified arrangement; this allows for the installation of the conveyor belt 31; the conveyor belt can be roughly divided into two sections, one being an inclined section extending below the right end of the chain mesh belt 21, and the other being a horizontal section extending out of the discharge port 18. In this way, the metal workpiece is received, conveyed, drained, and dried, and finally output from the discharge port 18.

[0062] In fact, the rotating shafts are a first rotating shaft 35, a second rotating shaft 36, a third rotating shaft 38, and a fourth rotating shaft. The first rotating shaft 35 is rotatably mounted on the top of the mounting frame 33 and located at the top right end of the cleaning tank 1. The second rotating shaft 36 is rotatably mounted on the cleaning tank 1 at the outlet 18. The third rotating shaft 38 is rotatably mounted on the bottom of the mounting frame 33 and located below the limiting groove 28. The fourth rotating shaft is mounted below the first rotating shaft 35 and at the top right end of the cleaning tank 1. A guide wheel 37 is fitted on the fourth rotating shaft to guide the conveyor belt 31. Unlike conventional conveyor belts that are diagonally connected to the third rotating shaft 38 from the second rotating shaft 36, this embodiment achieves support for the conveyor belt 31 through the guiding action of the guide wheel 37, without affecting the water level setting of the water-based cleaning agent in the cleaning tank 1, ensuring that the water level can submerge the metal workpiece.

[0063] The drive mechanism 4 in this embodiment includes a servo motor 41, a drive wheel 42, a conveyor belt drive wheel 43, a crankshaft drive wheel 45, and a drive belt 44. The servo motor 41 is fixedly mounted on the cleaning tank 1. The drive wheel 42 is mounted on the output shaft of the servo motor 41. The conveyor belt drive wheel 43 is mounted on the second rotating shaft 36. An intermediate shaft is rotatably mounted on the cleaning tank. The crankshaft drive wheel 45 is mounted on the outer end of the intermediate shaft, and the inner end of the intermediate shaft is connected to the crankshaft 23. The drive belt 44 connects the drive wheel 42, the conveyor belt drive wheel 43, and the crankshaft drive wheel 45. The transmission connection between the intermediate shaft and the crankshaft 23 can be achieved through a universal joint.

[0064] When the servo motor 41 is powered on, it drives the conveyor belt power wheel 43 and the crankshaft power wheel 45 via the drive wheel 42 and drive belt 44. Simultaneously, the crankshaft power wheel 45 drives one crankshaft 23 to rotate, and the other crankshaft 23 is driven to rotate via the synchronous belt 29. The feed inlet 11 can be fitted with a conveyor belt for inputting metal workpieces for automatic input; it also works in conjunction with the output mechanism 3 for more automated cleaning.

[0065] In fact, the conveyor belt drive wheel 43 can also be installed on the first rotating shaft 35 or the third rotating shaft 38.

[0066] It is understandable that the intermediate shaft and crankshaft 23 can be installed on the cleaning tank 1 by means of packing seal; the timing belt 29 and the conveyor belt are made of materials with good corrosion resistance and waterproof performance.

[0067] In fact, in order to drive the crankshaft 23 or the conveyor belt 31 independently, a motor can be installed at the end of one of the crankshafts 23 outside the cleaning tank 1; a motor can also be installed at the end of the first rotating shaft 35, the second rotating shaft 36 or the third rotating shaft 38 to achieve independent drive.

[0068] The working principle of the water-based cleaning device in this embodiment is as follows:

[0069] Before cleaning the metal workpiece, add water-based cleaning agent to the cleaning tank 1, and add an appropriate amount of water as needed; adjust the connection of the synchronous belt 29 between the two crankshafts 23; connect the drive wheel 42, the conveyor belt power wheel 43, and the crankshaft power wheel 45 through the drive belt 44; and set the drive speed of the servo motor 41.

[0070] When cleaning metal workpieces, the metal workpieces are fed into the feed port 11 and fall onto the chain mesh belt 21. The servo motor 41 runs, driving the crankshaft 23 to rotate. The cams at different positions on the crankshaft 23 periodically contact the chain mesh belt 21 at the corresponding positions, causing the chain mesh belt 21 to undulate and swing, thus swaying the metal workpieces.

[0071] By raising the chain mesh belt 21 by lifting the lifting rod 22, the left end of the chain mesh belt 21 is higher than the right end, which can transfer the metal workpiece to the conveyor belt 31, and then output it through the conveyor belt 31.

[0072] During output, the power of the servo motor 41 is transmitted to the conveyor belt 31 through the conveyor belt drive wheel 43 to transport and drain the metal workpiece; then, the electric heating tube heats the drying chamber 13 to dry the metal workpiece, which is then output from the discharge port 18. A material frame can be placed at the discharge port 18 to receive and temporarily store the metal workpiece.

[0073] The above provides a detailed description of the water-based cleaning device provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
