Description

Technical Field

[0001] This application relates to the field of water-based paint can cleaning technology, and in particular to a device for collecting and cleaning residues inside water-based paint cans. Background Technology

[0002] As is well known, water-based paints use water as a solvent, saving a significant amount of resources; eliminating the risk of fire during construction; reducing air pollution; and using only a small amount of low-toxicity alcohol ether organic solvents, thus improving working environment conditions. The organic solvent content (of the paint) in typical water-based coatings is between 5% and 15%, while cathodic electrophoretic coatings have reduced it to below 1.2%, demonstrating a significant effect on reducing pollution and saving resources.

[0003] Currently, in related technologies, a search reveals that a utility model with patent publication number CN219648305U discloses a collection and cleaning device for residues in water-based paint cans, including an internal gear disk, an internal gear groove on the inner wall of the internal gear disk, a bearing ring fixedly installed on the lower surface of the internal gear disk, the inner diameter of the bearing ring being smaller than the inner diameter of the internal gear disk, a center plate located at the center of the internal gear disk, a bearing fixedly installed in the center of the center plate, and a sun gear located above the center plate, the diameter of the center plate being larger than the diameter of the sun gear.

[0004] Regarding the aforementioned technologies, although they are constructed using components such as an internal gear disc, a central plate, a sun gear, planetary gears, and a cleaning brush arm, they can automatically scrape residue from the inner wall of water-based paint cans and collect it into a collection tray. However, the applicant has found that in actual production, water-based paint cans are not simply cylindrical. To adapt to different storage, transportation, and usage scenarios, the existing technologies often have cleaning brush arms that are either fixed structures or adjustable structures that can only adapt to standard cylindrical can walls. These structures are difficult to flexibly conform to the complex curved surfaces of irregularly shaped can walls, resulting in certain limitations in use and insufficient practicality.

[0005] Therefore, it is necessary to propose a device for collecting and cleaning residues inside water-based paint cans. Utility Model Content

[0006] The purpose of this invention is to provide a device for collecting and cleaning residues in water-based paint cans, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0027] 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.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Please see Figures 1-4In this embodiment of the present invention, a device for collecting and cleaning residues in water-based paint cans includes:

[0030] Mounting base 1;

[0031] The electric push rod 2 is detachably connected to the mounting base 1, and the output end of the electric push rod 2 is fixedly connected to the mounting plate 3;

[0032] The drive motor 4 is detachably connected to the bottom of the mounting plate 3, and the output shaft of the drive motor 4 is detachably connected to the connecting plate 5, which has multiple mounting holes.

[0033] Two L-shaped connecting brackets 6 are fixedly connected to the L-shaped connecting brackets 6. The connecting threaded post 7 is adapted to the mounting hole, and the connecting threaded post 7 is detachably connected to the mounting hole through the mounting ring 8.

[0034] Two scrapers 9 are installed in the L-shaped connecting bracket 6 through mounting slots;

[0035] A positioning component is provided at the bottom of the mounting base 1, which is used to fix and limit the mounting base 1 in the use position.

[0036] This device for collecting and cleaning residues inside water-based paint cans involves several steps. First, adjust the scraper 9 to fit the shape and inner diameter of the can. Hold the L-shaped connecting bracket 6 and align the threaded post 7 at its top with the corresponding mounting hole on the connecting plate 5. Use the positioning ring 16 inside the mounting hole to ensure precise insertion of the threaded post 7. Then tighten the mounting bolt 8 to secure the L-shaped connecting bracket 6, ensuring the scraper 9 fits snugly against the curved surface of the can. Next, move the device to the work position, placing it directly above the can to be cleaned, and then start the process. The positioning component fixes the mounting base 1 to the paint can. Then, the drive motor 4 and the electric control push rod 2 are activated. The output shaft of the drive motor 4 drives the connecting plate 5 to rotate, which in turn drives the L-shaped connecting frame 6 and the scraper 9 to rotate synchronously, scraping off the water-based paint residue on the can wall. At the same time, the electric control push rod 2 drives the mounting plate 3 to move up and down slowly, so that the scraper 9 can cover all areas of the can wall from top to bottom, avoiding local residue. During the cleaning process, the residual paint scraped off by the scraper 9 can fall naturally to the bottom of the can and be collected and disposed of after the cleaning is completed.

[0037] exist Figure 1-3 In the middle: the positioning component includes three positioning seats 10, which are symmetrically positioned at the bottom of the mounting base 1. The mounting base 1 is provided with a threaded ring 11, and an adjusting threaded post 12 is threadedly installed inside the threaded ring 11. One end of the adjusting threaded post 12 is provided with a composite suction cup 13, and the ends of the three adjusting threaded posts 12 that are far apart from each other are provided with a turntable body 14.

[0038] This device for collecting and cleaning residues inside water-based paint cans features a structure where three symmetrically distributed positioning seats 10 ensure balanced force distribution, preventing instability caused by single-point positioning. Operators can drive the adjusting threaded column 12 along the threaded ring 11 simply by rotating the turntable body 14, without the need for tools. This allows for flexible adaptation to water-based paint can openings of varying heights and diameters. The composite suction cup 13 at the end of the adjusting threaded column 12 adheres tightly to the edge of the can opening, creating a stable positioning effect. This effectively prevents the device from shifting or shaking during cleaning due to the rotation of the scraper 9 or the raising and lowering of the electrically controlled push rod 2, ensuring consistent contact between the scraper 9 and the can wall, improving the uniformity and thoroughness of residue cleaning, and preventing damage to the can opening caused by device displacement.

[0039] exist Figure 1-4 In the middle: the electric control push rod 2 is detachably installed in the mounting base 1 via the mounting ring 15. Multiple mounting holes are provided with positioning rings 16, which are adapted to the connecting threaded post 7. Two strip handles 17 are fixedly connected to the mounting base 1, and the outer fixed sleeve of the strip handles 17 is provided with anti-slip rubber sleeves 18.

[0040] It should also be noted that the mounting ring 15 makes the electric control push rod 2 and the mounting base 1 detachable. When the electric control push rod 2 malfunctions or needs maintenance, it can be quickly disassembled and replaced without disassembling the whole device, reducing maintenance difficulty and downtime. The positioning ring 16 in the mounting hole can accurately guide and limit the connecting threaded post 7, preventing the connecting threaded post 7 from shifting during installation, ensuring the stability of the L-shaped connecting frame after the spacing and angle are adjusted, and thus ensuring the fitting accuracy of the scraper 9 and the tank wall. The two strip handles 17 provide convenient force points for moving the device, and the external anti-slip rubber sleeves 18 can increase the friction between the hand and the handle, so that even if the operator's hands are contaminated with water-based paint residue or oil, they can hold it stably and prevent the device from slipping.

[0041] In this embodiment, the electric actuator 2 and the drive motor 4 are commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, so we will not go into detail here. Both the electric actuator 2 and the drive motor 4 are equipped with matching control switches. The installation position of the control switches is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0042] The implementation principle of a collection and cleaning device for residues inside water-based paint cans according to an embodiment of this application is as follows: First, the operator aligns the connecting threaded post 7 at the top of the L-shaped connecting frame with the corresponding mounting hole on the connecting plate 5. The positioning ring 16 in the mounting hole achieves precise guidance and limitation of the connecting threaded post 7, ensuring that the connecting threaded post 7 is vertically inserted into the mounting hole. Then, the mounting screw ring 8 is tightened to fix the L-shaped connecting frame. The distance and angle between the two L-shaped connecting frames are flexibly adjusted by selecting different mounting hole positions so that the scraper 9 can closely fit the curved surface of the can wall. Then, the operator holds the strip handle 17 with anti-slip rubber sleeve 18 on the mounting base 1 with both hands and moves it directly above the paint can to be cleaned. The turntable body 14 on the three positioning bases 10 is rotated to drive the adjusting threaded post 12 to rotate and move down along the threaded ring 11 until the composite suction cup 13 at the end of the adjusting threaded post 12 is tightly adsorbed on the edge of the paint can opening. The three symmetrical The distributed composite suction cups 13 form a triangular stable support. The self-locking characteristic of the threaded engagement prevents the adjusting threaded column 12 from loosening, ensuring that the device does not shift or shake during the cleaning process. After positioning, the cleaning operation is started. The electric control push rod 2 is fixed in the mounting base 1 by the mounting ring 15. After starting, the drive mounting plate 3 drives the connecting plate 5, L-shaped connecting frame and scraper 9 to move up and down slowly. At the same time, the drive motor 4 is started, and its output shaft drives the connecting plate 5 to rotate, so that the scraper 9 scrapes the water-based paint residue on the tank wall in a rotating manner. The combination of up and down movement and rotation ensures that the scraper 9 covers all areas of the tank wall from top to bottom, avoiding local residue. The scraped water-based paint residue naturally falls to the bottom of the tank. After cleaning is completed, the equipment is turned off, and the turntable body 14 is rotated in the opposite direction to make the composite suction cups 13 detach from the tank opening. The device is removed by the strip handle 17, and the residue at the bottom of the tank is collected and processed uniformly.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
