Description

Technical Field

[0001] This application relates to the field of casting processing technology, and in particular to a cleaning and drying integrated machine and cleaning process. Background Technology

[0002] Currently, after some castings are processed and manufactured, oil stains often adhere to the surface of the castings, and residual sand and other impurities usually adhere to the surface of the inner cavity of the castings. Therefore, it is usually necessary to clean the castings after processing and manufacturing to avoid residual sand, oil stains and other contaminants affecting the quality of the castings.

[0003] In traditional casting cleaning processes, manual cleaning is usually used to remove residual sand, oil, and other debris from the surface of the castings. However, manual cleaning is not only labor-intensive and inefficient, but also makes it difficult to guarantee the cleaning quality.

[0004] Furthermore, to address the shortcomings of manual casting cleaning, casting cleaning machines have been gradually developed and applied in casting cleaning processes. Current casting cleaning machines typically involve immersing the casting in water, then removing it or draining the water. While this method improves cleaning efficiency and reduces labor intensity, the cleaning quality is poor, failing to effectively remove residual sand and oil from the casting surface. Therefore, further improvements are warranted. Summary of the Invention

[0005] In order to improve the efficiency of casting cleaning while ensuring the cleaning quality, this application provides an integrated cleaning and drying machine and cleaning process.

[0006] In the first aspect, this application provides a washing and drying integrated machine, which adopts the following technical solution: A washing and drying integrated machine includes a conveyor line for conveying castings to be cleaned; between the input and output ends of the conveyor line, a fixed-point spray cleaning device, a fixed-point spray rinsing device, a mobile spray rinsing device, a hot air drying device, and a vacuum drying device are sequentially arranged.

[0007] By adopting the above technical solution, during the operation, the castings to be cleaned are placed on the material tray at the input end of the conveyor line for loading. After loading, the castings are sequentially fed into the fixed-point spray cleaning equipment, fixed-point spray rinsing equipment, mobile spray rinsing equipment, hot air drying equipment, and vacuum drying equipment for corresponding cleaning and drying treatments. Finally, they are unloaded at the output end of the conveyor line. Due to the use of multi-process automated cleaning and drying, it not only improves the efficiency of casting cleaning and reduces labor intensity, but also ensures the cleaning quality and effectively removes residual sand and oil stains from the surface of the castings.

[0008] Optionally, the fixed-point spray cleaning equipment includes a casing, inside which a cleaning chamber is formed, and windows are provided on both sides of the cleaning chamber for the conveyor line to feed or discharge the castings; a cleaning component for cleaning is provided in the cleaning chamber; the cleaning component includes a fixed base suspended and fixedly installed in the cleaning chamber, and a lifting base is installed below the fixed base and its lifting is controlled by a first drive component; an outer turntable is installed at the bottom of the lifting base and the outer turntable is controlled by a second drive component; a first nozzle is installed circumferentially at the bottom of the outer turntable, and the first nozzle is vertically arranged and faces inward.

[0009] By adopting the above technical solution, when the casting is sent into the cleaning chamber of the fixed-point spray cleaning equipment by the conveyor line, the first nozzle falls to the outside of the casting as the lifting base descends; then, the outer turntable is started to control the first nozzle to rotate around the outer periphery of the casting, and at the same time the first nozzle sprays high-concentration cleaning liquid onto the casting for cleaning.

[0010] Optionally, an inner turntable is also installed at the bottom of the lifting platform. The inner turntable is coaxially arranged with the outer turntable and is controlled simultaneously by the second driving component. An inner cleaning head is detachably installed at the bottom of the inner turntable.

[0011] By adopting the above technical solution, in actual operation, when the casting is a cylindrical part with an internal cavity, such as a motor housing, the inner cleaning head is installed; otherwise, the inner cleaning head is removed. When cleaning is performed after the inner cleaning head is installed, the inner cleaning head descends synchronously with the lifting platform and is inserted into the inner cavity of the casting at the same time as the first nozzle descends. As the inner turntable rotates, the inner cleaning head cleans the inner cavity of the casting, thus cooperating with the first nozzle to clean the casting both inside and out.

[0012] Optionally, the second driving component includes a drive motor fixedly mounted on the lifting base, an internal gear ring fixedly mounted on the bottom of the outer turntable, the internal gear ring being coaxially arranged with the outer turntable, and a first transmission gear mounted on the motor shaft of the drive motor, the first transmission gear meshing with the internal gear ring.

[0013] By adopting the above technical solution, in actual operation, the drive motor drives the internal gear ring through the first transmission gear, thereby controlling the rotation of the outer turntable.

[0014] Optionally, an external gear ring is fixedly installed on the inner turntable, and the external gear ring is coaxially arranged with the inner turntable; a second transmission gear is installed between the external gear ring and the internal gear ring, the second transmission gear is rotatably installed on the lifting base, and the second transmission gear meshes with both the internal gear ring and the external gear ring.

[0015] By adopting the above technical solution, when the outer turntable rotates, the inner gear ring on the outer turntable drives the outer gear ring on the inner turntable through the second transmission gear, thereby driving the inner turntable to rotate, so as to control the rotation of the inner cleaning head.

[0016] Optionally, the internal cleaning head includes a central rod, which is a retractable telescopic rod comprising an upper rod portion and a lower rod portion retractable into the upper rod portion; a plurality of first support rods are spaced apart on the outer periphery of the central rod, one end of each first support rod being hinged to the upper rod portion of the central rod; a middle portion of a second support rod is connected between the first support rods and the central rod, one end of the second support rod being hinged to the first support rod, and the other end of the second support rod being hinged to the lower rod portion of the central rod; a second nozzle is mounted on the end of the second support rod away from the central rod, the second nozzle being vertically positioned and facing outward, and a brush is mounted on the outward-facing side of the second nozzle; a retaining spring is mounted between the top of the second nozzle and the second support rod on the end of the second support rod away from the central rod.

[0017] By adopting the above technical solution, during the descent of the internal cleaning head, the middle rod gradually retracts after touching the bottom, that is, the lower part of the middle rod gradually retracts into the upper part. During this process, the second support rod controls the first support rod to gradually open outward like an umbrella, so as to slowly open the second nozzle until the brush on the second nozzle presses against the inner wall of the casting. Afterward, the entire internal cleaning head rotates, spraying high-concentration cleaning liquid into the inner wall of the casting through the second nozzle while simultaneously brushing it with the brush. Similarly, when the internal cleaning head is lifted and rises with the lifting platform, the lower part of the middle rod returns to its original position, and the second support rod retracts inward with the first support rod to gradually close the second nozzle.

[0018] Optionally, the bottom of the lower part of the middle rod is provided with a ball bearing that can be rolled.

[0019] By adopting the above technical solution, during the rotation cleaning process, the bottom of the inner cleaning head forms a rolling contact through the ball bearings at the bottom of the lower rod, thus ensuring the smooth rotation of the inner cleaning head.

[0020] Optionally, the vertical mounting height of the brush is adjustable.

[0021] By adopting the above technical solution, in actual working process, the upper and lower installation height of the brush can be adjusted according to the actual inner cavity height and width of the casting, so that the brush can better fit the inner cavity of the casting after being spread out, thus ensuring its cleaning effect.

[0022] Optionally, the first nozzle can be adjusted inward or outward.

[0023] By adopting the above technical solution, in actual work, since different castings have different widths, when processing castings with smaller widths, the first nozzle can be adjusted inwards accordingly to shorten the distance between the first nozzle and the casting, thereby ensuring the cleaning power of the first nozzle. Similarly, when processing castings with larger widths, the first nozzle can be adjusted outwards accordingly to allow for the rotation space of the first nozzle.

[0024] Secondly, this application provides a cleaning process, which adopts the following technical solution: A cleaning process, based on the aforementioned integrated cleaning and drying machine, is characterized by comprising the following steps: S1. Loading materials; S2, Targeted spray cleaning; S3. Targeted spray rinsing; S4. Moving spray rinsing; S5. Hot air drying; S6. Vacuum drying; S7. Feeding.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. During operation, castings to be cleaned are placed on material trays at the input end of the conveyor line for loading. After loading, the castings are sequentially fed into fixed-point spray cleaning equipment, fixed-point spray rinsing equipment, mobile spray rinsing equipment, hot air drying equipment, and vacuum drying equipment for corresponding cleaning and drying processes. Finally, they are unloaded at the output end of the conveyor line. Due to the use of multi-stage automated cleaning and drying, this process not only improves the efficiency of casting cleaning and reduces labor intensity, but also ensures cleaning quality, effectively removing residual sand and oil stains from the surface of the castings. 2. When the casting is sent into the cleaning chamber of the fixed-point spray cleaning equipment by the conveyor line, the first nozzle is lowered to the outside of the casting by the lifting base; then, the outer turntable is started to control the first nozzle to rotate around the outer circumference of the casting, and at the same time the first nozzle sprays high-concentration cleaning liquid onto the casting for cleaning. 3. In actual operation, when the casting is a cylindrical part with an internal cavity, such as a motor housing, install the inner cleaning head; otherwise, remove the inner cleaning head. When cleaning is performed after installing the inner cleaning head, the inner cleaning head descends synchronously with the lifting platform and is inserted into the inner cavity of the casting as the first nozzle descends. As the inner turntable rotates, the inner cleaning head cleans the inner cavity of the casting, thus cooperating with the first nozzle to clean the casting both inside and out. 4. During the descent of the internal cleaning head, the middle rod gradually retracts after touching the bottom, meaning the lower part of the middle rod gradually retracts into the upper part. During this process, the second support rod controls the first support rod to gradually open outwards like an umbrella, slowly opening the second nozzle until the brush on the second nozzle presses against the inner wall of the casting. Afterwards, the entire internal cleaning head rotates, spraying a high-concentration cleaning solution onto the inner wall of the casting through the second nozzle while simultaneously scrubbing with the brush.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a washing and drying integrated machine.

[0034] Reference Figure 1A washing and drying integrated machine includes a conveyor line 100 for conveying castings to be cleaned, and a fixed-point spray cleaning device 200, a fixed-point spray rinsing device 300, a mobile spray rinsing device 400, a hot air drying device 500, and a vacuum drying device 600 are sequentially arranged between the input end 101 and the output end 102 of the conveyor line 100.

[0035] During operation, the castings to be cleaned are placed on the material tray at the input end 101 of the conveyor line 100 for loading. After loading, the castings are sequentially fed into the fixed-point spray cleaning equipment 200, the fixed-point spray rinsing equipment 300, the mobile spray rinsing equipment 400, the hot air drying equipment 500, and the vacuum drying equipment 600 for corresponding cleaning and drying treatments. Finally, they are unloaded at the output end 102 of the conveyor line 100. Due to the use of multi-process automated cleaning and drying, it not only improves the efficiency of casting cleaning and reduces labor intensity, but also ensures the cleaning quality and effectively removes residual sand and oil stains from the surface of the castings.

[0036] Reference Figure 1 Specifically, in this embodiment, the fixed-point spray cleaning equipment 200 includes a housing 201, a cleaning chamber 202 is formed inside the housing 201, and windows are opened on both sides of the cleaning chamber 202 for the conveyor line 100 to send the castings in or out, and a cleaning component 203 for cleaning is provided in the cleaning chamber 202.

[0037] Referring to Figure 2, specifically, the cleaning component 203 includes a fixed base 1 suspended and fixedly installed within the cleaning chamber 202. A lifting base 2 is installed below the fixed base 1 and its lifting is controlled by a first drive component 3. An outer turntable 4 is installed at the bottom of the lifting base 2, and an inner turntable 7 is also installed at the bottom of the lifting base 2. The inner turntable 7 and the outer turntable 4 are coaxially arranged and synchronously controlled by a second drive component. A first nozzle 6 is circumferentially installed at the bottom of the outer turntable 4, and the first nozzle 6 is vertically arranged and faces inward. An inner cleaning head 8 is installed at the bottom of the inner turntable 7 via a hanging rod 9 and is detachably mounted.

[0038] When the casting is fed into the cleaning chamber 202 of the fixed-point spray cleaning equipment 200 via the conveyor line 100, the first nozzle 6 descends to the outside of the casting as the lifting base 2 descends. Then, the outer turntable 4 is activated to control the first nozzle 6 to rotate around the outer circumference of the casting, while simultaneously spraying a high-concentration cleaning solution onto the casting for cleaning. When the casting is a cylindrical part with an internal cavity, such as a motor housing, the inner cleaning head 8 is installed; otherwise, it is removed. When the inner cleaning head 8 is installed and cleaning is performed, the inner cleaning head 8 descends synchronously with the lifting base 2 as the first nozzle 6 descends, inserting into the inner cavity of the casting. As the inner turntable 7 rotates, the inner cleaning head 8 cleans the inner cavity of the casting, working in conjunction with the first nozzle 6 to clean the casting both internally and externally.

[0039] Reference Figure 2 Specifically, in this embodiment, the first driving component 3 is a cylinder, which is vertically and fixedly installed on the top of the fixed base 1, with its piston rod extending downward through the fixed base 1. The lifting base 2 is fixedly installed on the piston rod end of the first driving component 3 to control the lifting and lowering of the lifting base 2. Vertical guide rods 31 are fixedly installed on both the left and right sides of the top of the lifting base 2, and these guide rods 31 slide through the fixed base 1 to assist in the rising or falling of the lifting base 2.

[0040] Reference Figure 2 and Figure 3 Specifically, the second driving component includes a drive motor 51 fixedly installed on the lifting base 2, an internal gear ring 52 fixedly installed on the bottom of the outer turntable 4, the internal gear ring 52 being coaxially arranged with the outer turntable 4, a first transmission gear 53 being installed inside the internal gear ring 52, the first transmission gear 53 meshing with the internal gear ring 52, and being installed on the motor shaft of the drive motor 51.

[0041] An external gear ring 54 is fixedly mounted on the inner turntable 7 and is coaxially arranged with the inner turntable 7. A second transmission gear 55 is installed between the external gear ring 54 and the inner gear ring 52. The second transmission gear 55 is rotatably mounted on the lifting base 2 and simultaneously meshes with the inner gear ring 52 and the external gear ring 54.

[0042] In actual operation, the drive motor 51 drives the internal gear ring 52 through the first transmission gear 53, thereby controlling the rotation of the outer turntable 4. At the same time, when the outer turntable 4 rotates, the internal gear ring 52 on the outer turntable 4 drives the external gear ring 54 on the inner turntable 7 through the second transmission gear 55, thereby driving the inner turntable 7 to rotate, so as to control the rotation of the inner cleaning head 8.

[0043] Reference Figure 2 In this embodiment, there are two first nozzles 6, which are evenly spaced. In other embodiments, the number of first nozzles 6 can be three, four, or other similar quantities.

[0044] Reference Figure 2 The first nozzle 6 is tubular, and the outlets in the first nozzle 6 are evenly spaced along its length. The first nozzle 6 is fixedly installed on the outer turntable 4 by an L-shaped rod, and both the horizontal and vertical parts of the L-shaped rod are length-adjustable rods, so that the first nozzle 6 can be adjusted inward or outward by adjusting the length of the horizontal part of the L-shaped rod.

[0045] In actual operation, since different castings have different widths, when processing castings with smaller widths, the first nozzle 6 can be adjusted inwards to shorten the distance between the first nozzle 6 and the casting, thereby ensuring the cleaning power of the first nozzle 6. Similarly, when processing castings with larger widths, the first nozzle 6 can be adjusted outwards to allow for rotation space.

[0046] Reference Figure 4 In this embodiment, the internal cleaning head 8 includes a central rod 81, which is a retractable telescopic rod comprising an upper rod portion 811 and a lower rod portion 812 retractable within the upper rod portion 811. A plurality of first support rods 82 are spaced apart on the outer periphery of the central rod 81. One end of each first support rod 82 is hinged to the upper rod portion 811 of the central rod 81. A second support rod 83 is connected between the first support rods 82 and the central rod 81, with one end of the second support rod 83 hinged to the first support rod 82 and the other end hinged to the lower rod portion 812 of the central rod 81. A second nozzle 84 is mounted on the end of the second support rod 83 furthest from the central rod 81. The second nozzle 84 is vertically positioned and faces outwards, and a brush 85 is mounted on the outward-facing side of the second nozzle 84. The end of the second support rod 83 furthest from the central rod 81 is hinged to the middle of the second nozzle 84. A holding spring 86 is installed between the top of the second nozzle 84 and the second support rod 83, and the two ends of the holding spring 86 are respectively connected to the second nozzle 84 and the second support rod 83 to maintain the second nozzle 84.

[0047] During the descent of the internal cleaning head 8, the middle rod 81 gradually retracts after touching the bottom, meaning that the lower rod portion 812 of the middle rod 81 gradually retracts into the upper rod portion 811. During this process, the second support rod 83 controls the first support rod 82 to gradually open outwards like an umbrella, slowly opening the second nozzle 84 until the brush 85 on the second nozzle 84 presses firmly against the inner wall of the casting. Afterwards, the entire internal cleaning head 8 rotates, spraying a high-concentration cleaning solution onto the inner wall of the casting through the second nozzle 84 while simultaneously scrubbing with the brush 85.

[0048] Similarly, when the inner cleaning head 8 is lifted and rises with the lifting base 2, the lower rod 812 in the middle rod 81 is reset, and the second support rod retracts inward to the first support rod, so as to gradually retract the second nozzle 84.

[0049] In this embodiment, the retractable and repositionable return mechanism between the lower rod portion 812 within the upper rod portion 811 can be achieved by installing a spring internally. In other embodiments, a damping rod can be used instead of the middle rod 81.

[0050] In this embodiment, the bottom of the lower rod portion 812 of the middle rod 81 is rotatably embedded with ball bearings 813, so that during the rotation cleaning process, the bottom of the inner cleaning head 8 forms a rotatable contact through the ball bearings 813 at the bottom of the lower rod portion 812, thereby ensuring the smooth rotation of the inner cleaning head 8.

[0051] In this embodiment, the vertical installation height of the brush 85 is adjustable, for example, by means of vertical slot installation, which will not be elaborated here. In actual operation, since the actual inner cavity height and width of different cylindrical cavity castings are different, it is necessary to adjust the vertical installation height of the brush 85 according to the actual inner cavity height and width of the casting, so that the brush 85 can better fit the inner cavity of the casting after being spread out, thereby ensuring its cleaning effect.

[0052] The implementation principle is as follows: During operation, the castings to be cleaned are placed on the material tray at the input end 101 of the conveyor line 100 for loading. After loading, the castings are sequentially fed into the fixed-point spray cleaning equipment 200, the fixed-point spray rinsing equipment 300, the mobile spray rinsing equipment 400, the hot air drying equipment 500, and the vacuum drying equipment 600 for corresponding cleaning and drying treatments. Finally, the castings are unloaded at the output end 102 of the conveyor line 100.

[0053] When the casting is fed into the cleaning chamber 202 of the fixed-point spray cleaning equipment 200 via the conveyor line 100, the first nozzle 6 descends to the outside of the casting as the lifting base 2 descends. Then, the outer turntable 4 is activated to control the first nozzle 6 to rotate around the outer circumference of the casting, while simultaneously spraying a high-concentration cleaning solution onto the casting for cleaning. When the casting is a cylindrical part with an internal cavity, such as a motor housing, the inner cleaning head 8 is installed; otherwise, it is removed. When the inner cleaning head 8 is installed and cleaning is performed, the inner cleaning head 8 descends synchronously with the lifting base 2 as the first nozzle 6 descends, inserting into the inner cavity of the casting. As the inner turntable 7 rotates, the inner cleaning head 8 cleans the inner cavity of the casting, working in conjunction with the first nozzle 6 to clean the casting both internally and externally.

[0054] During operation, as the inner cleaning head 8 descends, the middle rod 81 gradually retracts after touching the bottom, meaning the lower rod portion 812 of the middle rod 81 gradually retracts into the upper rod portion 811. During this process, the second support rod 83 controls the first support rod 82 to gradually open outwards like an umbrella, slowly opening the second nozzle 84 until the brush 85 on the second nozzle 84 presses firmly against the inner wall of the casting. Afterwards, the entire inner cleaning head 8 rotates, spraying a high-concentration cleaning solution onto the inner wall of the casting through the second nozzle 84 while simultaneously scrubbing with the brush 85.

[0055] This application also discloses a cleaning process.

[0056] Reference Figure 5 A cleaning process, based on the aforementioned integrated cleaning and drying machine, includes the following steps: S1. Loading materials; S2, Targeted spray cleaning; S3. Targeted spray rinsing; S4. Moving spray rinsing; S5. Hot air drying; S6. Vacuum drying; S7. Feeding.

[0057] Reference Figure 1 During operation, castings to be cleaned are placed on material trays at the input end 101 of the conveyor line 100 for loading. Next, the castings are conveyed along the conveyor line 100 into the fixed-point spray cleaning equipment 200 for fixed-point spray cleaning. After fixed-point spray cleaning, the castings are conveyed along the conveyor line 100 into the fixed-point spray rinsing equipment 300 for fixed-point spray rinsing. After fixed-point spray rinsing, the castings are conveyed along the conveyor line 100 into the mobile spray rinsing equipment 400 for mobile spray rinsing. After mobile spray rinsing, the castings are conveyed along the conveyor line 100 into the hot air drying equipment 500 for hot air drying. After hot air drying, the castings are conveyed along the conveyor line 100 into the vacuum drying equipment 600 for vacuum drying. After vacuum drying, the castings are conveyed along the conveyor line 100 to the unloading end for unloading.

[0058] Because it adopts multi-stage automated cleaning and drying, it not only improves the efficiency of casting cleaning and reduces labor intensity, but also ensures the cleaning quality and effectively removes residual sand and oil stains from the surface of castings.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
