Description

Technical Field

[0001] The present invention relates to the technical field of steel product processing, and particularly to a steel ball cleaning machine. Background Art

[0002] Steel balls are important basic components in modern industry and are widely used in fields such as bearings, hardware, electronics, iron art, mechanical equipment, electric power, mines, and metallurgy, playing a huge role in the development of the national economy. In terms of applications, steel balls can be divided into two categories: wear-resistant steel balls used in the crushing industry and bearing steel balls used in the precision bearing industry. Wear-resistant steel balls (abbreviated as grinding balls) are the most widely used products in current industrial practices; bearing steel balls have a long history and wide application in the precision bearing industry and daily life. It can be said that steel balls exist wherever there is rotation.

[0003] The production methods of steel balls generally include forging, rolling, semi-solid forming, and casting. No matter which method is used for processing, after processing, the steel balls need to be cleaned to remove impurities such as dust, metal particles, and oil stains attached to the steel balls during the processing process. Subsequently, surface treatment of the steel balls is required to ensure that the steel balls will not have problems such as surface corrosion, wear, or even cracks during storage and transportation.

[0004] Current steel ball cleaning devices usually place steel balls in a water-containing container and clean the steel balls by means of vibration, spraying, turbines, etc. For example, the Chinese invention patent with the publication number CN106694432A discloses a steel ball cleaning device, which includes a strip-shaped loading platform. The strip-shaped loading platform is provided with through holes, and the inner side walls of the through holes are provided with elastic layers. A collection channel is communicated below the through holes. A rotating shaft is connected below the collection channel. A conical groove is formed in the rotating shaft, and the conical groove communicates with the collection channel. A collection device is arranged on the side of the rotating shaft. An air pump is arranged on one side of the rotating shaft where the small end of the conical groove is located. It also includes a Y-shaped high-pressure water pipe. The Y-shaped high-pressure water pipe includes a main pipe, a first branch pipe, and a second branch pipe. The main pipe is connected to a water pump. A spray head is arranged on the first branch pipe. The second branch pipe is connected to a turbine. The turbine is coaxially connected to a first bevel gear. The first bevel gear meshes with a second bevel gear, and the second bevel gear is connected to the rotating shaft. With this device, not only can the stains on the steel balls be easily removed, but also after the steel balls are cleaned, they are automatically collected at the same time, greatly reducing the labor intensity of workers.

[0005] The above-mentioned device combines a nozzle and a turbine to create a swirling water body for cleaning steel balls. However, there are certain problems with these methods. That is, this water-washing method is relatively easy to remove impurities such as dust and metal particles, but for stains with strong adhesiveness such as oil stains, only the friction between the steel balls can be relied on to remove them. Considering that the surface of the steel ball is spherical, the mutual contact surface is small, and the surface of the steel ball itself is smooth, it is difficult to clean such stains thoroughly. Summary of the Invention

[0006] Aiming at the deficiencies in the prior art, the present invention provides a steel ball cleaning machine, which solves the problem that it is difficult to thoroughly clean stains with strong adhesiveness such as oil stains in the existing water-washing method.

[0007] According to an embodiment of the present invention, a steel ball cleaning machine includes a closed housing, a cleaning channel arranged inside the housing, and a cleaning component and a rinsing component arranged in sequence along the cleaning channel. At the top of one end of the housing, a feeding port is provided, and a feeding channel is arranged below the feeding port. The feeding channel communicates with one end of the cleaning channel. The cleaning channel is horizontally arranged, and the end of the cleaning channel far from the feeding channel penetrates to the outside of the housing.

[0008] The cleaning component includes a fixing device and a cleaning device arranged opposite to each other up and down in the same area of the cleaning channel. The fixing device is used to fix the steel ball and only contacts the bottom end of the steel ball. The cleaning device cleans the outer surface of the steel ball when the steel ball is in a fixed state.

[0009] The rinsing component includes a spray head and a filter plate arranged in sequence up and down. The spray head faces the cleaning channel below, and a drain pipe is also arranged at the bottom of the filter plate. The drain pipe communicates with the outside of the housing.

[0010] Further, a feeding funnel is also arranged at the position of the housing corresponding to the feeding port.

[0011] Further, a pushing device is also arranged at the end of the cleaning channel corresponding to the feeding channel. The pushing device includes a first telescopic rod arranged parallel to the cleaning channel and a pushing plate perpendicular to the cleaning channel. The pushing plate is arranged close to the end face of the cleaning channel, and the pushing plate can move towards the inside of the cleaning channel under the drive of the first telescopic rod.

[0012] Further, the cleaning component includes a first cleaning mechanism and a second cleaning mechanism arranged in sequence along the cleaning channel.

A concave portion corresponding to the surface curvature of the steel ball is provided in the middle of the loading tray, and an electromagnet is further provided inside the concave portion.

[0014] Further, the cleaning device includes an electric clamp and a motor arranged at one end where the electric clamp closes. The electric clamp includes two semi-circular clamping heads. When the clamping heads close, there is a vacant portion corresponding to one end of the fixing device, and at this time, the center position of the clamping heads corresponds to the center height of the steel ball. The electric clamp is perpendicular to the extending direction of the cleaning channel, and a driving motor is further arranged at one end of the electric clamp away from the fixing device, and the output shaft of the driving motor is arranged vertically.

[0015] Further, a third telescopic rod is provided on the side of the fixing device away from the cleaning channel. The cleaning device is arranged outside the fixing device relative to the cleaning channel, and a through opening corresponding to the size of the fixing device is provided on the cleaning channel corresponding to the cleaning device. The third telescopic rod can drive the fixing device to pass through the cleaning channel and extend to the position where the cleaning device is located.

[0016] Further, a pre-cleaning component is further provided in the cleaning channel between the feeding channel and the cleaning component, and the structure of the pre-cleaning component is the same as that of the rinsing component.

[0017] Further, a water inlet pipe is further provided on the housing. After bifurcating in the housing, the water inlet pipe is simultaneously connected to the spray heads in the pre-cleaning component and the rinsing component; the drain pipes below the filter plates of the pre-cleaning component and the rinsing component are simultaneously connected to a sewage tank provided at the bottom of the housing.

[0018] Further, a partition component is further provided at the bottom of the cleaning channel in front of the cleaning component.

The cleaning component includes a fixing device and a cleaning device which are arranged opposite to each other up and down in the same area of the cleaning channel. The steel balls moving above it can be fixed by the fixing device, and then the cleaning device performs friction cleaning on the surface of the steel balls, so as to thoroughly remove the stains on the surface of the steel balls. Subsequently, the spray heads of the rinsing component spray water downward to wash off the dust and the remaining impurities separated by friction on the surface of the steel balls. Thus, a better cleaning effect is achieved. Description of the Drawings

Detailed implementation manners

[0025] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0026] As Figure 1 shown, an embodiment of the present invention provides a steel ball cleaning machine, which includes a closed housing 1, a cleaning channel 3 arranged inside the housing 1, and a cleaning assembly and a rinsing assembly 7 arranged in sequence along the cleaning channel 3. In this embodiment, the housing 1 is in a strip-shaped cuboid structure. An inlet is opened at the top of one end of the housing 1, and a feeding funnel 11 is further arranged at the position of the housing 1 corresponding to the inlet. A feeding channel 2 is arranged below the inlet, and the feeding channel 2 communicates with one end of the cleaning channel 3. The cleaning channel 3 is horizontally arranged, and the end of the cleaning channel 3 far from the feeding channel 2 is an outlet and penetrates to the outside of the housing 1. Preferably, a downwardly inclined discharge plate 12 is further arranged at the outlet of the cleaning channel 3 in this embodiment, and the discharge plate 12 can extend into the next processing device or into the storage device.

[0027] As Figure 2As shown in the figure, in this embodiment, the cleaning assembly includes a fixing device and a cleaning device which are arranged opposite to each other up and down in the same area of the cleaning channel 3. The fixing device is used to fix the steel ball and only contacts the bottom end of the steel ball. The cleaning device cleans the outer surface of the steel ball when the steel ball is in a fixed state. In a specific solution, the fixing device includes a loading tray 51. The loading tray 51 is parallel to the side surface of the corresponding cleaning channel 3. A recess 511 corresponding to the surface curvature of the steel ball is provided in the middle of the loading tray 51. An electromagnet (not shown) is also provided inside the recess 511. When the steel ball rolls onto the loading tray 51, its bottom sinks into the recess 511. Subsequently, the electromagnet is activated to tightly adsorb and fix the steel ball on the surface of the loading tray 51.

[0028] As Figure 3 shown, correspondingly, the cleaning device includes an electric clamp 52 and a motor 54 arranged at one end where the electric clamp 52 closes. The electric clamp 52 includes two semi-circular clamp heads 521. When the clamp heads 521 are closed, there is a vacant part at one end corresponding to the fixing device, so as to cooperate with the bottom end area where the steel ball sinks into the recess 511. And at this time, the center position of the clamp head 521 corresponds to the center height of the steel ball. The electric clamp 52 is perpendicular to the extending direction of the cleaning channel 3. A driving motor 54 is also provided at one end of the electric clamp 52 away from the fixing device. The output shaft of the driving motor 54 is vertically arranged. After the steel ball is adsorbed and fixed, the motor 54 drives the electric clamp 52 to rotate radially around the vertical diameter of the steel ball, so that the surface of the steel ball can be frictionally cleaned to wash off the adhered oil stains and other impurities. Preferably, a sponge cleaning layer 522 is also provided on the inner side surface of the clamp head 521, so as to better contact the surface of the steel ball and improve the cleaning effect.

[0029] Preferably in this embodiment, the cleaning assembly includes a first cleaning mechanism 5 and a second cleaning mechanism 6 arranged in sequence along the cleaning channel 3. In the first cleaning mechanism 5, the fixing device is located below the cleaning channel 3, and the cleaning device is located inside the cleaning channel 3 above the fixing device; in the second cleaning mechanism 6, the fixing device is located above the cleaning channel 3, and the cleaning device is located inside the cleaning channel 3 below the fixing device. In this way, the steel ball first contacts the fixing device in the first cleaning mechanism 5 through the bottom, and then contacts the fixing device in the second cleaning mechanism 6 through the top, avoiding that the contact part with the fixing device in a single cleaning is not cleaned.

[0030] In a further solution, a third telescopic rod 53 is arranged on one side of the fixing device away from the cleaning channel 3. The cleaning device is arranged outside the fixing device relative to the cleaning channel 3, and a through opening corresponding to the size of the fixing device is arranged on the cleaning channel 3 corresponding to the cleaning device. The third telescopic rod 53 can drive the fixing device to extend through the cleaning channel 3 to the position where the cleaning device is located. In this way, the steel balls can be moved to an area outside the cleaning channel 3 for friction cleaning, avoiding the work of the cleaning device being obstructed by other steel balls that are tightly connected before and after.

[0031] The rinsing assembly 7 includes a spray head 42 and a filter plate 41 arranged in sequence from top to bottom. The spray head 42 faces the cleaning channel 3 below. A drain pipe 44 is also arranged at the bottom of the filter plate 41, and the drain pipe 44 communicates to the outside of the housing 1. There are still dust, metal particles and other impurities rubbed off on the surface of the steel balls after friction cleaning in the cleaning assembly. At this time, they can be removed by means of water washing. Preferably, a pre-cleaning assembly 4 is also arranged in the cleaning channel 3 between the feeding channel 2 and the cleaning assembly. The structure of the pre-cleaning assembly 4 is the same as that of the rinsing assembly 7. In this way, particulate impurities such as dust and metal particles can be eluted in advance before the cleaning device, avoiding damage to the surface of the steel balls during the friction cleaning process.

[0032] As a cooperation with the rinsing assembly 7, a water inlet pipe 43 is also arranged on the outer shell. After bifurcating in the housing 1, the water inlet pipe 43 is simultaneously connected to the spray heads 42 in the pre-cleaning assembly 4 and the rinsing assembly 7; the drain pipes 44 below the filter plates 41 of the pre-cleaning assembly 4 and the rinsing assembly 7 are simultaneously connected to a sewage tank 13 arranged at the bottom of the housing 1. The sewage tank 13 can be connected to a sewage treatment station to avoid sewage discharge.

[0033] In a further solution of this embodiment, a pushing device is further provided at one end of the cleaning channel 3 corresponding to the feeding channel 2. The pushing device includes a first telescopic rod 91 arranged parallel to the cleaning channel 3 and a pushing plate 9 perpendicular to the cleaning channel 3. The pushing plate 9 is arranged close to the end face of the cleaning channel 3, and the pushing plate 9 can move towards the inside of the cleaning channel 3 under the drive of the first telescopic rod 91. By the operation of the first telescopic rod 91, the moving speed of the steel balls can be controlled. Each time the steel balls enter the cleaning device for cleaning, the first telescopic rod 91 extends to push the steel balls towards the outlet. Subsequently, the first telescopic rod 91 contracts to let the steel balls in the feeding channel 2 fall to replenish, and then the next push is carried out. Cooperating therewith, a partition component is further provided at the bottom of the cleaning channel 3 in front of the cleaning component. The partition component includes a partition plate 8 arranged perpendicular to the cleaning channel 3. An opening is provided on the bottom surface of the cleaning channel 3 corresponding to the partition plate 8, so that the partition plate 8 can extend from the bottom to the inside of the cleaning channel 3. A second telescopic rod 81 is further provided below the partition plate 8, and the second telescopic rod 81 drives the partition plate 8 to move in the vertical direction. When the steel balls are being cleaned in the cleaning device, since the fixing device will move to the outside of the cleaning channel 3, the partition plate 8 also rises correspondingly to prevent the adjacent steel balls in the front from rolling backwards.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
