[0001] The invention relates to the technical field of wear-resistant ball surface cleaning devices, in particular to a wear-resistant ball surface cleaning device. Background Art

[0002] After the wear-resistant balls are cast, their surfaces will absorb impurities such as molding sand, iron filings and burrs on the sand core; current wear-resistant ball processing companies generally use the method of collision between wear-resistant balls to remove impurities on the surface of the wear-resistant balls; the collision of wear-resistant balls is random, and the cleaning effect of different positions of the same wear-resistant ball is inconsistent, resulting in poor cleaning effect; at the same time, when the wear-resistant balls collide with each other, the burrs and deformation on the surface of the wear-resistant balls will be absorbed by the wear-resistant balls, causing unnecessary trouble for cleaning, which needs to be solved urgently. Summary of the Invention

[0003] In order to solve the technical problems existing in the background technology, the present invention provides a wear-resistant ball surface cleaning device.

[0004] The present invention provides a wear-resistant ball surface cleaning device, comprising:

[0005] The machine body has a feed end, a discharge end, and a flow channel connecting the two ends for the circulation of wear-resistant balls;

[0006] Cleaning assembly, which is detachably installed in the flow channel and has a brush for cleaning the attachments on the surface of the wear-resistant balls;

[0007] The flip assembly includes a roller shaft with a cam cross section and a baffle arranged obliquely on one side of the roller shaft. A gap is reserved between the baffle and the roller shaft. When the roller shaft rotates, the wear-resistant balls in the gap can continuously reciprocate up and down and move closer to or away from the brush.

[0008] The baffle is rotatably mounted on the machine body, which has a first and second working positions. When the baffle is in the first working position, the wear-resistant balls are located in the gap. When the baffle is switched to the second working position, the wear-resistant balls enter the flow channel from the gap and roll to the discharge end for discharge.

[0009] A first driving assembly is used to drive the roller shaft so that the roller shaft rotates continuously;

[0010] The second driving assembly is used to drive the baffle to rotate so that the baffle switches between the first working position and the second working position.

[0011] Preferably, a plurality of grooves are arranged at intervals on the baffle to form a plurality of first processing stations. When the baffle is at the first station and the wear-resistant ball is close to the brush, the wear-resistant ball always sticks to the inner wall of the groove.

[0012] Preferably, the groove specifically includes a fitting portion and an extension portion, the extension portion is arranged above the fitting portion and is connected to the fitting portion, the fitting portion has a shape that fits the surface wall of the wear-resistant ball, the extension portion is larger than the fitting portion and is irregularly arranged; when the baffle is in the first position and the wear-resistant ball is in the lowest position, the wear-resistant ball is affixed to the bottom wall of the fitting portion, and when the wear-resistant ball is in the highest position, the wear-resistant ball is affixed to the top wall of the extension portion.

[0013] Preferably, a plurality of annular grooves are arranged at intervals on the roller shaft to form a plurality of second processing stations, and the plurality of second processing stations are arranged in one-to-one correspondence with the plurality of first processing stations. When the wear-resistant ball enters the gap, the wear-resistant ball is located between the first processing station and the second processing station.

[0014] Preferably, the brush has first type of bristles and second type of bristles, the first type of bristles and the second type of bristles are arranged alternately, the length of the first type of brush is greater than the length of the second type of brush, and when the wear-resistant ball is against the top wall of the extension part, the wear-resistant ball contacts and squeezes the second type of brush.

[0015] Preferably, the cleaning device also includes an attachment collection chamber and a first branch channel, the flow channel has a straight portion, the bottom of the straight portion has a flat plate connected to the bottom end of the baffle and arranged horizontally, the flat plate has a plurality of through holes to form a first branch channel, the attachment collection chamber is connected to the first branch channel, and the attachment collection chamber also has a cleaning port for cleaning attachments therein.

[0016] Preferably, the bottom wall of the attachment collecting chamber is arranged to be inclined so that the attachments are collected at the bottom thereof.

[0017] Preferably, the end of the flat plate away from the baffle further has a protrusion.

[0018] Preferably, the baffle further has a plurality of guide grooves perpendicular to the roller shaft so that the attached matter can flow downward along the guide grooves.

[0019] The wear-resistant ball surface cleaning device proposed in the present invention is internally provided with a roller shaft with a cam-shaped cross-section, which together with the baffle forms a gate for controlling the flow of the wear-resistant balls inside the body. When the wear-resistant balls cannot pass, the roller shaft can drive the wear-resistant balls to move up and down repeatedly, thereby intermittently contacting the brush installed in the body to clean the surface of the wear-resistant balls. Since the brush can be deformed and the wear-resistant balls will also roll when moving up and down, the consistency of the wear-resistant ball surface cleaning can be effectively improved. At the same time, the cleaning of the wear-resistant balls relies on the friction of the brush and the roller shaft and the baffle on the wear-resistant balls. The mutual collision force between the wear-resistant balls is relatively small, which can effectively prevent the deformed burrs from being adsorbed on the wear-resistant balls, further improving the cleaning effect of the device.

[0025] like Figure 1 As shown, Figure 1 This is a structural schematic diagram of an embodiment of a wear-resistant ball surface cleaning device proposed by the present invention.

[0026] Reference Figure 1 , Figure 4 and Figure 5 The present invention provides a wear-resistant ball surface cleaning device, comprising:

[0027] The machine body 1 has a feed end 11, a discharge end 12 and a flow channel 13 connecting the two for the circulation of wear-resistant balls;

[0028] The cleaning component 2 is detachably mounted in the flow channel 13 and has a brush 21 for cleaning the surface of the wear-resistant balls;

[0029] The flip assembly 3 includes a roller shaft 31 with a cam cross section and a baffle 32 arranged obliquely on one side of the roller shaft 31. A gap is reserved between the baffle 32 and the roller shaft 31. When the roller shaft 31 rotates, the wear-resistant balls in the gap can continuously reciprocate up and down and move closer to or away from the brush 21.

[0030] The baffle 32 is rotatably mounted on the machine body 1. The machine body 1 has a first position and a second position. When the baffle 32 is in the first position, the wear-resistant balls are located in the gap. When the baffle 32 is switched to the second position, the wear-resistant balls enter the flow channel 13 through the gap and roll to the discharge end 12 for discharge.

[0031] A first driving assembly is used to drive the roller shaft 31 so that the roller shaft 31 rotates continuously;

[0032] The second driving assembly is used to drive the baffle 32 to rotate so that the baffle 32 switches between the first position and the second position.

[0033] It should be noted that the first driving component may be a motor component, and the second driving component may be a cylinder component.

[0034] When the device is used, the baffle 32 is first adjusted to the first position, and appropriate wear-resistant balls are added into the gap through the feed end 11, and the roller 31 is driven to rotate by the first drive component. Since the cross-section of the roller 31 is set as a cam, the wear-resistant balls can be driven to move back and forth along the baffle 32 during its rotation, and are always in contact with the roller 31 during the process. There is friction between the roller 31 and the baffle 32 and the wear-resistant balls, and the friction force can disconnect the burrs from the wear-resistant balls. During the up and down reciprocating movement of the wear-resistant balls, they can intermittently contact the brush 21, and the brush 21 can brush off the molding sand, iron filings, burrs and other attachments attached to the surface of the wear-resistant balls. The cleaned attachments will move down along the baffle for collection. After the wear-resistant balls are cleaned, the baffle 32 is switched from the first position to the second position through the second drive component. At this time, the gap becomes larger, and the wear-resistant balls enter the flow channel 13 and are discharged from the discharge end 12.

[0035] During the cleaning process, the brush 21 can be deformed and the wear-resistant balls will roll when moving up and down, which can effectively improve the consistency of the cleaning of the wear-resistant ball surface. At the same time, the cleaning of the wear-resistant balls relies on the friction of the brush 21 and the roller 31 and the baffle 32 on the wear-resistant balls. The mutual collision force between the wear-resistant balls is relatively small, which can effectively prevent the deformed burrs from being adsorbed on the wear-resistant balls, further improving the cleaning effect of the device.

[0036] Reference Figure 2 In a further embodiment, a plurality of grooves 321 are arranged at intervals on the baffle 32 to form a plurality of first processing stations. When the baffle 32 is in the first station and the wear-resistant ball is close to the brush 21, the wear-resistant ball always sticks to the inner wall of the groove 321. The groove 321 specifically includes a fitting portion 3211 and an extension portion 3212. The extension portion 3212 is arranged above the fitting portion 3211 and is connected to the fitting portion 3211. The fitting portion 3211 has a shape that fits the surface wall of the wear-resistant ball. The extension portion 3212 is larger than the fitting portion 3211 and is irregularly arranged. When the baffle 32 is in the first station and the wear-resistant ball is in the lowest position, the wear-resistant ball sticks to the bottom wall of the fitting portion 3211. When the wear-resistant ball is in the highest position, the wear-resistant ball sticks to the top wall of the extension portion 3212.

[0037] In this further embodiment, a plurality of first processing stations consisting of grooves 321 are provided on the baffle 32. When cleaning, the wear-resistant balls are placed in the first processing station, which can effectively avoid collisions between the wear-resistant balls, thereby preventing burrs and impurities such as iron filings from being deformed and adsorbed on the surface of the wear-resistant balls, thereby affecting the cleaning efficiency. At the same time, the grooves 321 are provided with a fitting portion 3211 having a shape that matches the surface wall of the wear-resistant balls and an irregularly shaped extension portion 3212. Due to the irregular setting of the extension portion 3212, the wear-resistant balls will randomly flip during the upward movement, which can improve the randomness of cleaning by the brush 21. When the wear-resistant balls rise to the highest point, they will also randomly flip when they descend, which can also improve the randomness of contact between the roller 31 and the baffle 32 and the wear-resistant balls.

[0038] Reference Figure 3 In the specific structural design, a plurality of annular grooves 311 are arranged at intervals on the roller shaft 31 to form a plurality of second processing stations. The plurality of second processing stations are arranged in a one-to-one correspondence with the plurality of first processing stations. When the wear-resistant balls enter the gap, the wear-resistant balls are located between the first processing station and the second processing station. This arrangement facilitates the placement of the wear-resistant balls in the plurality of first processing stations, facilitates operation, and improves processing efficiency.

[0039] In a further embodiment, the brush 21 has first type of bristles and second type of bristles, the first type of bristles and the second type of bristles are arranged alternately, the length of the first type of brush is greater than the length of the second type of brush, and when the wear-resistant ball is against the top wall of the extension portion 3212, the wear-resistant ball contacts and squeezes the second type of brush.

[0040] It should be noted that the brush 21 can be configured to have a plurality of bristles of different lengths. At the same time, the shorter the bristles are and the higher the hardness is, the more effectively the cleaning effect of the brush 21 can be improved.

[0041] In this further embodiment, after the wear-resistant balls rise to a certain level, they are opened to contact the first type of brush, and the first type of brush cleans the wear-resistant balls for the first time. As the wear-resistant balls move upward, the force of the wear-resistant balls squeezing the brush increases, which can improve the cleaning effect of the brush 21. When the first type of brush is completely bent, the cleaning effect will deteriorate. At this time, the wear-resistant balls are cleaned for the second time by the second type of brush, so that the device has a better cleaning effect.

[0042] Reference Figure 1 In order to separate the attachments from the wear-resistant balls, the cleaning device also includes an attachment collection chamber 5 and a first branch channel. The flow channel 13 has a straight portion 131. The bottom of the straight portion 131 has a flat plate 4 connected to the bottom end of the baffle 32 and arranged horizontally. The flat plate 4 has multiple through holes to form a first branch channel. The attachment collection chamber 5 is connected to the first branch channel. The attachment collection chamber 5 also has a cleaning port for cleaning the attachments inside it.

[0043] When the device is in operation, the attachments that have fallen off after being cleaned by the brush 21, the roller 31 and the baffle 32 will fall along the baffle 32 into the first branch channel and enter the attachment collection chamber 5 for storage. Since the first branch channel is composed of multiple through holes, some attachments will accumulate in the through holes. When the wear-resistant balls are cleaned and need to be discharged, the baffle is driven by the second drive component to switch from the first station to the second station. At this time, the wear-resistant balls roll to the flat plate 4, which will give the flat plate 4 an impact force, causing the attachments accumulated in the through holes to fall into the attachment collection chamber 5 for storage.

[0044] In the specific structural design, the bottom wall of the attachment collecting chamber 5 is arranged to be inclined so that the attachments are collected at the bottom thereof, which facilitates the subsequent cleaning of the attachments stored therein.

[0045] Reference Figure 1 Preferably, the end of the flat plate 4 away from the baffle 32 also has a protrusion 41, which can isolate attachments and at the same time slow down the wear-resistant balls falling to the protrusion 41, thereby reducing the feeding speed of the wear-resistant balls.

[0046] Reference Figure 2 In the specific structural design, the baffle 32 also has a plurality of guide grooves 322 perpendicular to the roller shaft 31 so that the attached matter can flow downward along the guide grooves 322.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
