DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] Embodiment 1: Figure 1-5 As shown, a steel ball cleaning device according to an embodiment of the present invention comprises a body 1, wherein an ultrasonic unit and a cleaning pool 100 are arranged in the body 1, wherein the cleaning pool 100 is filled with a cleaning liquid, and a placement mechanism 2 for placing steel balls is arranged on the body 1;

[0038] The placement mechanism 2 includes: a frame 21 slidably arranged at the top of the body 1; a plurality of rotating rods 22 rotatably arranged in the frame 21; a counterweight block 23 and a support plate 24 respectively arranged on both sides of the rotating rod 22, the support plate 24 is inclined under the action of the counterweight block 23, and a surrounding plate is arranged on the surrounding side of the top of the support plate 24; a limit block 25 arranged on the frame 21 to limit the support plate 24; and holes 241 evenly distributed at the bottom of the support plate 24, the hole grooves 241 are through-through from top to bottom, and the hole diameter of the hole grooves 241 is smaller than the outer diameter of the steel ball.

[0039] Specifically, the machine body 1, the ultrasonic unit and the cleaning tank 100 adopt an ultrasonic cleaning machine structure. The type and ratio of the cleaning liquid should be determined according to the material of the steel ball and the nature of the dirt to ensure that the concentration and temperature of the cleaning liquid meet the requirements. For example, the cleaning liquid can be a sodium oleate soap solution, and the cleaning temperature is 40°C; the frame 21 can move up and down, and a lifting rod is provided in the machine body 1. A hook plate 211 is provided at the top of the frame 21. After the frame 21 is hung on the lifting rod, the lifting rod can be started to drive the frame 21 to move up and down, so that the frame 21 can enter and exit the cleaning tank 100. Of course, the frame 21 can also be taken manually. Figure 2 As shown, multiple rotating rods 22 are evenly distributed in the vertical direction, the counterweight block 23 is located on the left side of the rotating rod 22, and the support plate 24 is located on the right side of the rotating rod 22. For a single support plate 24, the number of steel balls placed on the support plate 24 is not greater than the number of holes 241, and preferably the number of steel balls is less than the number of holes 241; the weight of the counterweight block 23 is greater than the weight of the support plate 24; the limit block 25 is arranged on the right side wall of the frame 21.

[0040] Initially, the support plate 24 is in an inclined state with the left side lower and the right side higher. A steel ball is placed on each support plate 24 at the right end of the support plate 24. The steel ball rolls to the left along the inclined support plate 24. The steel ball falls into the hole groove 241 and is fixed during the rolling process, so that the steel ball is evenly distributed on the support plate 24 for the first time. The steel ball that does not fall into the hole groove 241 rolls to the leftmost side of the support plate 24.

[0041] After all the steel balls fall on the support plate 24, the weight of the support plate 24 and the steel balls is greater than the weight of the counterweight 23, and the support plate 24 starts to rotate clockwise. The rotation amplitude of the support plate 24 is limited by the limit block 25. After the support plate 24 rotates to the horizontal, it contacts the limit block 25 and then stops rotating. When the support plate 24 stops, the steel balls that have not fallen into the hole groove 241 will roll to the right along the support plate 24 under the action of inertia force and fall into the empty hole groove 241, so that a secondary uniform distribution can be performed, so that the steel balls on the support plate 24 are more evenly distributed.

[0042] After all the steel balls are laid on the support plates 24, the frame 21 is placed in the cleaning pool 100, all the steel balls are immersed in the cleaning liquid, the ultrasonic unit is started, and the steel balls are ultrasonically cleaned. After the cleaning is completed, the frame 21 is taken out so that the cleaned steel balls can be subsequently processed. When the device is in use, the steel balls are placed in layers by setting multiple layers of support plates 24, and the inclined support plates 24 are rotated so that the steel balls are evenly staggered on the support plates 24, thereby improving the problem of affecting the cleaning effect due to the accumulation of steel balls, and improving the cleaning effect.

[0043] It should be noted that the size of the hole 241 is selected according to the outer diameter of the steel ball and the tilt angle of the support plate 24. When the support plate 24 is tilted, the steel ball rolls on the support plate 24, and the steel ball falling into the hole 241 will not cause a jamming effect on the rolling of the remaining steel balls behind. Other designs that can meet this requirement are suitable for the manufacture of the support plate 24 and the hole 241. The position of the limit block 25 can be designed according to the specific situation. After the support plate 24 contacts the limit block 25, the support plate 24 can also be in an inclined state where the right side is slightly lower than the left side, further ensuring that after the right end of the support plate 24 moves down to contact the limit block 25, the steel ball on the left side that has not fallen into the hole 241 can roll to the right.

[0044] like Figure 2-8 As shown, the placement mechanism 2 also includes: a pressure plate 26 slidably arranged on the support plate 24; a return spring 27 used to drive the pressure plate 26 to approach the support plate 24, and the two ends of the return spring 27 are respectively connected to the pressure plate 26 and the support plate 24; a discharge port 242 is arranged on the support plate 24, and the discharge port 242 is located between the rotating rod 22 and the pressure plate 26.

[0045] Specifically, the enclosure on the top of the support plate 24 includes three sides, and the pressure plate 26 can move up and down relative to the support plate 24. Initially, the pressure plate 26 is close to the support plate 24 under the action of the return spring 27. The pressure plate 26 and the enclosure together form a quadrilateral fence, which surrounds the steel ball in the middle to prevent the steel ball from rolling off the support plate 24.

[0046] like Figure 2-8 As shown, the placement mechanism 2 also includes a receiving groove 28 arranged on the inner bottom wall of the frame 21. After the pressure plate 26 moves up, the steel ball inside the support plate 24 rolls under the pressure plate 26 and passes through the discharge port 242 and falls into the receiving groove 28.

[0047] Specifically, initially, the pressing plate 26 moves downward under the action of gravity, sealing the left feed opening 242, and the pressing plate 26 and the supporting plate 24 form a hole groove 241 that blocks the circumference; after cleaning, the lifting plate 29 is moved upward to drive all the pressing plates 26 to move upward, and the steel balls roll away from under the pressing plate 26, and flow downward through the feed opening 242, accumulating at the bottom, completing the collection of the cleaned steel balls. A discharge port can be set at the bottom of the receiving tank 28, and the discharge port is opened to discharge all the steel balls in the receiving tank 28.

[0048] After the steel balls fall downward through the discharge openings 242 , they do not touch the pressing plate 26 below, so as to ensure that the steel balls can pass through the multiple discharge openings 242 and finally fall into the receiving groove 28 .

[0049] like Figure 2-3 As shown, the weight of the counterweight block 23 is greater than the weight of the support plate 24 and the pressure plate 26 .

[0050] Specifically, when the support plate 24 is unloaded, the gravity of the left counterweight block 23 is greater than the gravity of the right support plate 24 and the pressure plate 26, so that the support plate 24 is inclined.

[0051] like Figure 2-7As shown, the placement mechanism 2 also includes: a limiting guide rail 243 arranged on the support plate 24 to guide the pressure plate 26; a protruding rod 261 fixedly connected to the pressure plate 26; a lifting plate 29 slidably arranged on the frame 21, and a plurality of horizontal plates corresponding to the protruding rod 261 are provided in the lifting plate 29. After the lifting plate 29 moves up, it drives the protruding rod 261 to move up and drives the support plate 24 to rotate.

[0052] Specifically, the pressing plate 26 can slide within a certain stroke relative to the supporting plate 24; the frame 21 is provided with a slide rail 213 corresponding to the lifting plate 29, and the slide rail 213 is provided with a limiter for limiting the moving stroke of the lifting plate 29. Initially, the lifting plate 29 is located at the bottom of its moving stroke under the action of its own gravity. As needed, when the lifting plate 29 is moved upward, after the lifting plate 29 moves to the top of its stroke relative to the frame 21, the lifting plate 29 is continued to move upward, which can drive the frame 21 to move upward. Therefore, the frame 21 can also be taken out of the cleaning tank 100 by the lifting plate 29.

[0053] The initial state of the support plate 24 is as follows Figure 2 After the support plate 24 is loaded with a steel ball, it rotates to a horizontal state. At this time, the protruding rod 261 is located above the horizontal plate, as shown Figure 3 As shown; after the ultrasonic cleaning of the steel balls is completed, the lifting plate 29 is moved upward, and the lifting plate 29 drives the pressing plate 26 and the support plate 24 to rotate counterclockwise through the cooperation with the protruding rod 261, and the support plate 24 becomes inclined, so that the steel balls roll out of the hole groove 241, so as to collect the cleaned steel balls.

[0054] like Figure 2-10 As shown, it also includes a positioning mechanism 3, which includes: a slide seat 31 slidably arranged on the frame 21; a baffle 32 arranged on the slide seat 31 for blocking the support plate 24, the baffle 32 is rotatably connected to the slide seat 31, the baffle 32 is a unidirectional rotation structure, and a reset torsion spring is provided on the rotation axis of the baffle 32.

[0055] Specifically, a support 212 is provided on the frame 21 , and the slide 31 is slidably installed in the support 212 . The slide 31 can slide back and forth along the axial direction of the rotating rod 22 .

[0056] like Figure 2-10 As shown, the positioning mechanism 3 also includes: a push spring 33 provided on the slide seat 31 for pushing the baffle 32 close to the support plate 24; a lever 34 fixed to the support plate 24, and a slope corresponding to the lever 34 is provided on the baffle 32.

[0057] Specifically, two ends of the push spring 33 are connected to the support 212 and the slide seat 31 respectively, and a slope is provided on the right side of the baffle 32 ; the force of the push spring 33 is greater than the force of the return spring 27 .

[0058] Initially, the support plate 24 is tilted, and the lever 34 is located on the left side of the baffle 32. During the clockwise rotation of the support plate 24, the lever 34 moves to the lower right side of the baffle 32. After the support plate 24 rotates to a horizontal position, the steel ball is ultrasonically cleaned.

[0059] After the ultrasonic cleaning of the steel ball is completed, the lifting plate 29 is quickly moved upward. This rapid movement method can be achieved by manual operation or electric impact rod, and other methods that can achieve rapid upward movement of the lifting plate 29 are also applicable to this solution; after the lifting plate 29 is moved upward, the pressing plate 26 is driven upward by the convex rod 261, and the pressing plate 26 drives the support plate 24 to move upward together through the return spring 27, thereby causing the support plate 24 to rotate counterclockwise; during the counterclockwise rotation of the support plate 24, the lever 34 contacts the baffle 32, and the lever 34 collides with the baffle 32, causing the support plate 24 to pause, and the steel ball located in the hole groove 241 has a tendency to move to the left under the action of inertia, thereby contacting the hole groove 241 is separated, and the steel balls separated from the hole groove 241 move down along the support plate 24 and move to the top of the pressure plate 26; the lifting plate 29 continues to move up, and because the support plate 24 is blocked by the baffle plate 32, the lifting plate 29 continues to move up and drives the pressure plate 26 to move up relative to the support plate 24. During this process, the return spring 27 is stretched; after the pressure plate 26 moves up relative to the support plate 24, the pressure plate 26 moves away from the support plate 24, and the steel balls pass through the gap between the pressure plate 26 and the support plate 24 and roll down to the discharge port 242. Then, these steel balls pass through the discharge port 242 and fall into the receiving slot 28. In this way, the function of initial separation of the steel balls on the support plate 24 is realized;

[0060] After the initial separation, some of the steel balls may still remain in the hole groove 241, and the lifting plate 29 continues to move upward. When the force exerted by the lever 34 on the baffle plate 32 is greater than the force of the push spring 33, the lever 34 pushes the baffle plate 32 and the slide seat 31 to move, so that the baffle plate 32 is separated from the lever 34. Without the restraint of the baffle plate 32, under the action of the return spring 27, the support plate 24 continues to rotate counterclockwise and quickly approaches the pressure plate 26. The left wall of the frame 21 is provided with a limiter for limiting the rotation amplitude of the support plate 24. The support plate 24 rotates until it contacts the step and is blocked by the step, causing the support plate 24 to collide again. The remaining steel balls in the support plate 24 continue to move to the left under the action of inertia and roll out of the hole groove 241. Since the inclination of the support plate 24 is greater at this time and the inertia force is applied, the remaining steel balls are more likely to roll out of the hole groove 241, thereby achieving a secondary separation function for the steel balls remaining in the hole groove 241, thereby causing all the steel balls to detach from the hole groove 241 and fall into the receiving groove 28.

[0061] It should be noted that when the support plate 24 collides again, the support plate 24 may also collide with the pressure plate 26 after rotating counterclockwise.

[0062] By selecting and adjusting the material of the baffle 32, the movement direction of the slide 31 and other options, the system stability during operation can be ensured and the collision damage problem of system components can be improved. For example, the baffle 32 can be made of a material such as metal with a certain elasticity and reset ability, and a buffer structure is also provided on the baffle 32. The movement direction of the slide 31 and the movement direction of the lever 34 can be set to be inclined relative to each other.

[0063] In the conventional separation method, if one wants to utilize the inertia force to remove all the steel balls from the hole groove 241 at once, not only a larger inertia force needs to be provided, but also the steel balls in the upper and lower parts of the support plate 24 are subjected to different inertia forces, and some of the steel balls may be directly spilled to the outside of the support plate 24 or even the outside of the frame 21. Furthermore, if the spacing between the upper and lower layers of the support plates 24 is small, the rotation amplitude of the support plate 24 is too small, and the steel ball at the upper end of the support plate 24 moves to the left under the action of the larger inertia force, and will collide with the upper support plate 24 and fall back onto the support plate 24, and may be stuck in the hole groove 241 again, and the steel ball cannot be separated from the hole groove 241. Therefore, this method also requires the support plate 24 to rotate to a larger amplitude, resulting in an increase in the space occupied by the multi-layer support plate 24. In summary, this method is not suitable; this scheme designs a secondary separation structure, and the inertial force required for each separation is smaller, thereby reducing the possibility of steel balls spilling out of the support plate 24 under the action of inertial force. At the same time, it also reduces the power requirement for generating inertial force, that is, reduces the driving force for driving the lifting plate 29 to move upward, making it more convenient to use; in addition, the secondary separation method also reduces the requirement for the rotation amplitude of the support plate 24, and the support plate 24 can rotate within a smaller amplitude, thereby making the spacing between the multi-layer support plates 24 smaller, reducing space occupancy and making it more convenient to use.

[0064] like Figure 2-6 As shown, the slide seat 31 and the lifting plate 29 are staggered.

[0065] Specifically, the movement of the baffle plate 32 in the slide seat 31 does not interfere with the movement of the lifting plate 29 .

[0066] Embodiment 2: Figure 2-11 As shown, compared with Example 1, another embodiment of the present invention is: it also includes a feeding mechanism 4, the feeding mechanism 4 includes: a silo 41 arranged on the body 1; a plurality of storage grooves 42 arranged in the silo 41, the storage grooves 42 are used to place steel balls; a plurality of guide grooves 43 are arranged on the side walls of the frame 21, the bottoms of the storage grooves 42 and the guide grooves 43 are both provided with slopes, the outlet of the storage groove 42 is aligned with the guide groove 43, and the steel balls in the storage groove 42 fall into the support plate 24 via the guide groove 43.

[0067] Specifically, the guide groove 43 is disposed on the right side wall of the frame 21 , and the guide groove 43 is through from left to right. The left end of the guide groove 43 is located above the inclined support plate 24 , and the left side of the storage groove 42 is open.

[0068] like Fig.11As shown, the feeding mechanism 4 further includes a door plate 44 slidably disposed on the material bin 41 , the door plate 44 passes through the storage slot 42 , and a notch corresponding to the storage slot 42 is opened in the door plate 44 .

[0069] Specifically, initially, the door panel 44 is located below the moving range, the door panel 44 blocks the left side of the storage tank 42, steel balls are placed in the storage tank 42, the number of steel balls in each support plate 24 corresponds to each support plate 24, and the door panel 44 is used to prevent the steel balls from rolling out of the storage tank 42; the frame 21 is located above the cleaning pool 100, the right side wall of the frame 21 is close to the left side of the silo 41, and the right section of the guide groove 43 is aligned with the left side end of the storage tank 42.

[0070] When loading the steel balls into the support plate 24 , the door plate 44 is moved upward so that the notch in the door plate 44 is aligned with the storage slot 42 , and then the steel balls in the storage slot 42 roll onto the support plate 24 via the guide slot 43 , thereby achieving the function of placing the steel balls on the support plate 24 .

[0071] Working principle: Before cleaning the steel balls, put the steel balls to be cleaned into the storage tank 42, and move the frame 21 upward so that the frame 21 is aligned with the silo 41;

[0072] When the steel balls are loaded into the support plate 24, the door plate 44 is moved so that the notch in the door plate 44 is aligned with the storage groove 42, and then the steel balls in the storage groove 42 roll onto the support plate 24 via the guide groove 43;

[0073] The steel ball rolls to the left along the inclined support plate 24. During the rolling process, the steel ball falls into the hole groove 241 and is fixed, so that the steel ball is evenly distributed on the support plate 24 for the first time. The steel ball that does not fall into the hole groove 241 rolls to the leftmost side of the support plate 24.

[0074] After all the steel balls fall on the support plate 24, the weight of the support plate 24, the pressure plate 26 and the steel balls is greater than the weight of the counterweight block 23, and the support plate 24 starts to rotate clockwise. After the support plate 24 rotates to the right side and is horizontally lower, it contacts the limit block 25 and then stops rotating. When the support plate 24 stops, the steel balls that have not fallen into the hole groove 241 will roll to the right along the support plate 24 under the action of inertia force and fall into the empty hole groove 241, so that a secondary uniform distribution can be performed, so that the steel balls on the support plate 24 are more evenly distributed.

[0075] After all the steel balls are laid on the support plates 24, the frame 21 is placed into the cleaning tank 100 through the hook plate 211 so that all the steel balls are immersed in the cleaning liquid, and the ultrasonic unit is started to perform ultrasonic cleaning on the steel balls;

[0076] After the ultrasonic cleaning is completed, the lifting plate 29 is quickly lifted upward. After the lifting plate 29 moves upward, the pressing plate 26 is driven upward by the convex rod 261, and the pressing plate 26 drives the supporting plate 24 to move upward together through the return spring 27, thereby causing the supporting plate 24 to rotate counterclockwise; during the counterclockwise rotation of the supporting plate 24, the lever 34 contacts the baffle 32, and the lever 34 collides with the baffle 32, causing the supporting plate 24 to pause, and the steel ball located in the hole groove 241 has a tendency to move to the left under the action of inertia, thereby separating from the hole groove 241, and the steel ball separated from the hole groove 241 moves downward along the supporting plate 24 and moves to above the pressing plate 26;

[0077] The lifting plate 29 continues to move upward. Since the support plate 24 is blocked by the baffle plate 32, the lifting plate 29 continues to move upward, driving the pressing plate 26 to move upward relative to the support plate 24. During this process, the return spring 27 is stretched. After the pressing plate 26 moves upward relative to the support plate 24, the pressing plate 26 moves away from the support plate 24, and the steel balls pass through the gap between the pressing plate 26 and the support plate 24 and roll downward to the discharge port 242. Then, these steel balls pass through the discharge port 242 and fall into the receiving groove 28. In this way, the function of initially separating the steel balls on the support plate 24 is realized.

[0078] After the initial separation, some of the steel balls may still remain in the hole groove 241, and the lifting plate 29 continues to move upward. When the force exerted by the lever 34 on the baffle plate 32 is greater than the force exerted by the push spring 33, the lever 34 pushes the baffle plate 32 and the slide seat 31 to move, so that the baffle plate 32 is separated from the lever 34. The baffle plate 32 is no longer restrained. Under the action of the return spring 27, the support plate 24 continues to rotate counterclockwise and quickly approaches the pressure plate 26. The left wall of the frame 21 is provided with a rotation spring for the support plate 24. The support plate 24 rotates until it contacts the step and is blocked by the step. The remaining steel balls in the support plate 24 continue to move to the left under the action of inertia and roll out of the hole slot 241. Since the inclination of the support plate 24 is greater at this time, coupled with the action of inertia, the remaining steel balls are more likely to roll out of the hole slot 241, thereby realizing the function of secondary separation of the steel balls remaining in the hole slot 241, thereby making all the steel balls detach from the hole slot 241 and fall into the receiving slot 28.

[0079] Continue to lift the lifting plate 29 upwards, and after the frame 21 is taken out from the cleaning tank 100, the steel balls in the receiving grooves 28 can be taken out at one time, eliminating the trouble of taking out the steel balls from each support plate 24 one by one, and is easy to use.

[0080] When the device is in use, the rotation generated by the inclined support plate 24 is arranged, and the upper hole groove 241 is matched, so that the steel balls are evenly staggered and distributed on the support plate 24, which improves the problem of affecting the cleaning effect due to the accumulation of steel balls, and improves the cleaning effect. By setting the lifting plate 29, in the process of extracting the frame 21 from the cleaning pool 100, the support plate 24 is driven to collide twice, and the steel balls located in the hole groove 241 are separated twice, so that the steel balls are completely separated from the hole groove 241 and fall into the receiving groove 28 through the discharge port 242, so that the steel balls in the receiving groove 28 can be taken out at one time, eliminating the trouble of taking out the steel balls from each support plate 24 in turn, and it is convenient to use. By setting the two separation methods, not only the driving force for driving the lifting plate 29 to move upward is reduced, but also the requirements for the rotation amplitude of the support plate 24 are reduced. The support plate 24 can be rotated within a smaller amplitude, and then the spacing between the multi-layer support plates 24 can be made smaller, reducing the space occupied by the device.
