Description

Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to a novel device that can effectively improve the cleaning of varnish residue after impregnation of castings. Background Art

[0002] Dipping is a traditional method of paint coating, widely used in casting and other fields due to its advantages such as simplicity and minimal equipment requirements. However, workpieces with uneven surfaces, deep grooves, or blind holes may develop paint pooling at these locations after dipping. Incomplete cleaning of the pooled paint will directly affect the quality of the dip-coated layer.

[0003] Traditional cleaning methods involve manual cleaning with brushes, which is inefficient, time-consuming, and labor-intensive. With the development of technology, various vacuum cleaners are increasingly being used in industrial production.

[0004] For example, a pneumatic vacuum cleaner gun is disclosed in patent document CN215687413U, which includes an air gun. The front end of the air gun is connected to the upper air port of a negative pressure generator through a hollow connecting screw. The other end of the negative pressure generator is an air inlet, which is connected to a suction pipe. The lower part of the negative pressure generator is an air outlet, which is connected to a dust collection bag through a hollow dust outlet connecting screw.

[0005] According to existing technical documents, this pneumatic vacuum cleaner can only remove dust by suction from the air inlet. However, paint often adheres to the surface of castings, and relying solely on suction is not very effective for cleaning.

[0006] Therefore, this utility model optimizes and improves upon the problem of poor cleaning effect of pneumatic vacuum guns on the enamel residue in the slots of castings in the prior art. It proposes a new device that can automatically control the brush to remove the enamel residue and then use a vacuum gun to suck up the paint residue, so as to better solve the problems in the prior art.

[0026] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present utility model, and are therefore merely examples and should not be used to limit the scope of protection of the present utility model. The specific structure of the present utility model is as follows: Figures 1-4 As shown in the image.

[0027] A novel device for effectively improving the cleaning of enamel residue after impregnation of castings includes a three-way negative pressure pipe 1, a dust suction steel pipe 2 installed at the left end of the three-way negative pressure pipe 1, an air inlet steel pipe 3 installed at the right end of the three-way negative pressure pipe 1, and a dust exhaust hose 4 installed at the lower end of the three-way negative pressure pipe 1. The four components are internally connected. A second handle assembly is installed at the right end of the air inlet steel pipe 3, and the two are internally connected. The lower end of the second handle assembly is connected to a fixedly installed air compressor 6 via the air inlet hose 5. The other end of the dust exhaust hose 4 is installed on a fixedly installed dust collection bin 7, and the two are internally connected. A enamel residue cleaning component is fixedly installed on the dust suction steel pipe 2, and a first handle assembly is fixedly installed at the bottom of the right end of the three-way negative pressure pipe 1.

[0028] The three-way negative pressure pipe 1 is a three-way pipe with three pipe connection joints. Each of the three connection joints corresponds to a pipe channel. The right-side joint is used to connect to the pipe for supplying compressed gas, the left-side joint is used to connect to the dust suction pipe, and the lower joint is used to connect to the exhaust and dust discharge pipe. The right-side joint is positioned higher than the left-side joint. The three built-in channels of the three-way negative pressure pipe 1 converge at the middle position. When the air compressor 6 is working, the compressed gas enters the right built-in channel of the three-way negative pressure pipe 1 through the intake hose 5 and the intake steel pipe 3 in sequence, and then enters the dust exhaust hose 4 through the lower built-in channel of the three-way negative pressure pipe 1. When the compressed gas passes through the convergence position of the built-in channels, due to the high gas flow rate, the air at the convergence position is carried away, thus creating a certain negative pressure at that position. Under the action of the negative pressure, the left built-in channel of the three-way negative pressure pipe 1 generates a certain suction force, thereby sucking the paint from the position where the casting has a paint dent into the left built-in channel of the three-way negative pressure pipe 1 through the dust suction steel pipe 2. At the same time, driven by the compressed air flow, the sucked paint residue enters the lower built-in channel of the three-way negative pressure pipe 1, and finally enters the dust collection bucket 7 through the dust exhaust hose 4 along with the compressed gas.

[0029] This utility model has a paint caking removal component fixedly installed on the dust suction steel pipe 2. The paint caking removal component can more efficiently remove the paint in the grooves or holes on the surface of the casting that have paint caking defects. At the same time, a first handle component and a second handle component are provided at intervals on the right end of this utility model, so that the operator can hold the device with both hands for easy operation. The first handle component can control the operation and efficiency of the paint caking removal component.

[0030] In any of the above embodiments, it is preferred that the paint cleaning assembly includes a mounting base 8, which is fixedly sleeved on the left end of the suction steel pipe 2. A motor 9 is fixedly mounted on the top of the mounting base 8. The motor shaft of the motor 9 is arranged along the length direction of the suction steel pipe 2. The end of the motor shaft of the motor 9 is coaxially fixedly connected to one end of the rotating rod 10 through a coupling. A hemispherical brush 12 is fixedly connected to the other end of the rotating rod 10.

[0031] During operation, the operator holds the first and second handle assemblies with both hands respectively, controlling the hemispherical brush 12 to enter the groove or hole on the surface of the casting. Simultaneously, the first handle assembly controls the motor 9 to operate, thereby driving the rotating rod 10 to rotate coaxially, which in turn drives the hemispherical brush 12 to rotate. As the hemispherical brush 12 comes into contact with the painted surface of the casting, its continuous rotation efficiently removes the paint from the painted area. The removed paint residue is then sucked into the suction pipe 2 under negative pressure and finally enters the dust collection bin 7. The operating speed of the motor 9 can be controlled by the first handle assembly, allowing for flexible adaptation to different grooves or holes to achieve optimal working conditions.

[0032] In any of the above embodiments, preferably, the first handle assembly includes a connecting block 13, which is fixedly connected to the bottom of the right circumferential outer wall of the three-way negative pressure pipe 1. A hollow first handle 14 is fixedly connected to the bottom of the right end of the connecting block 13. A sliding connecting groove 27 is provided at the bottom of the connecting block 13 along its length direction. A through groove 15 is provided at the corresponding position on the left side wall of the first handle 14. The assembly also includes a toggle block 16, the upper end of which is movably inserted into the sliding connecting groove 27. The right end of the toggle block 16 passes through the through groove 15 and extends into the interior of the first handle 14. A speed adjustment component is provided at the corresponding position inside the first handle 14.

[0033] While holding the first handle 14, the operator presses the actuating block 16 with their finger. Under the action of external force, the actuating block 16 moves along the sliding connecting groove 27 into the first handle 14. At the same time, a speed adjustment component is fixedly installed at the corresponding position inside the first handle 14. With the cooperation of the actuating block 16 and the speed adjustment component, the motor speed can be flexibly adjusted.

[0034] In any of the above embodiments, it is preferred that the speed regulating component includes a mounting plate 11, the left sidewall of the mounting plate 11 is fixedly connected to the right end of the toggle block 16, the right sidewall of the mounting plate 11 is fixedly connected to the left end of a spring 17, the right end of the spring 17 is fixedly connected to a pressure plate 18, a pressure sensor 19 is fixedly connected to the right sidewall of the pressure plate 18, and the pressure sensor 19 is fixedly connected to the inner wall of the first handle 14.

[0035] When the actuating block 16 moves inward into the first handle 14 under the pressure of a finger, it drives the left end of the spring 17 to move to the right via the mounting plate 11, thereby compressing the spring 17 and transmitting the force to the fixed pressure plate 18. After receiving the pressure signal, the pressure sensor 19 controls the motor to rotate via an existing program. Different pressure applied by the finger results in different degrees of movement of the actuating block 16, and the pressure signal transmitted to the pressure sensor 19 via the spring 17 will also differ accordingly. Through the control of the existing program, different pressure signals can further control the motor 9 to operate at different speeds, thereby addressing the cleaning of different grooves or holes for paint contamination.

[0036] In any of the above embodiments, it is preferred that the second handle assembly includes a second handle 20, the interior of the second handle 20 is hollow, the upper end of the second handle 20 is fixedly connected to the right end of the air intake steel pipe 3 and the two are internally connected, and a perforated connector 21 is fixedly installed at the lower end of the second handle 20 and the two are internally connected, the perforated connector 21 is inserted into the inner cavity of the end of the air intake hose 5 and the two are internally connected.

[0037] An air intake channel is provided inside the second handle 20 along its length, and the upper end of the air intake channel is connected to the right end of the air intake steel pipe 3, and the lower end is connected to the air intake hose 5 through a perforated connector 21, so that the air compressor 6 can introduce compressed gas into the right-side built-in channel of the three-way negative pressure pipe 1.

[0038] In any of the above embodiments, it is preferred that a slide rail 22 is fixedly installed on the top of the actuating block 16, and a slide groove 23 is provided at the corresponding position on the top of the sliding connecting groove 27, and the slide rail 22 is movably engaged in the slide groove 23.

[0039] With the cooperation of the slide rail 22 and the slide groove 23, the actuating block 16 can slide more smoothly and stably along the sliding connection groove 27.

[0040] In any of the above embodiments, it is preferred that a switch button 24 for controlling the opening and closing of the air compressor 6 is fixedly installed on the second handle 20.

[0041] A switch button 24 is fixedly installed on the second handle 20, which allows the operator to flexibly control the opening and closing state of the air compressor 6 while holding the second handle 20.

[0042] In any of the above embodiments, it is preferred that a transparent protective cover 25 is fixedly connected to the mounting base 8, and the motor 9 is disposed inside the transparent protective cover 25.

[0043] The transparent protective cover 25 can prevent the paint residue from being cleaned off from entering the internal structure of the motor 9, thereby affecting the normal operation of the motor 9.

[0044] In any of the above embodiments, it is preferred that a one-way valve 26 for venting is fixedly installed on the top of the dust collection bin 7. The one-way valve 26 is used to discharge compressed gas.

[0045] Specific working principle:

[0046] The operator holds the first handle 14 and the second handle 20 with both hands to control the movement of the main structure of the device, and aligns the end of the suction steel pipe 2 with the groove or hole that needs to be cleaned. At the same time, the hemispherical brush 12 is extended into the groove or hole. Then, while holding the second handle 20 with one hand, the operator presses the switch button 24 to turn on the air compressor 6. The compressed gas passes through the intake hose 5 and the intake steel pipe 3 in sequence and enters the interior of the three-way negative pressure pipe 1. Then, it passes through the built-in channels on the right and lower sides of the three-way negative pressure pipe 1 in sequence, and then enters the interior of the dust collection bin 7 through the dust discharge hose 4. Then, while holding the first handle 14 with the other hand, slowly press the actuating block 16 to control the operating speed of the motor 9. Under the action of the motor 9, the hemispherical brush 12 rotates as it comes into contact with the inside of the casting groove, thereby removing the paint from the enamel-covered area. The removed paint residue enters the built-in channel on the left side of the three-way negative pressure pipe 1 under the suction of the suction pipe 2, and enters the dust collection bin 7 under the drive of compressed gas. When encountering areas that are difficult to clean, the pressure of the fingers on the actuating block 16 can be appropriately increased to increase the speed of the motor 9 and enhance the cleaning ability of the hemispherical brush 12, thus completing the cleaning process of the enamel-covered area of ​​the casting.
