Description

Technical Field

[0001] This invention belongs to the field of ultrasonic cleaning technology and relates to an ultrasonic cleaning agitation device. Background Technology

[0002] Ultrasonic cleaning is a technique that uses the cavitation effect generated by ultrasound in a liquid to clean the surface of objects. It is widely used in various fields, from precision instruments to medical devices, from industrial production to daily life, playing a vital role. To ensure that all parts of the workpiece placed in the cleaning tank are cleaned, it is often necessary to agitate the workpiece up and down during cleaning to achieve a more thorough cleaning.

[0003] For example, a projectile lifting mechanism for an ultrasonic cleaner has been designed and a Chinese patent has been applied for, with application number 202022433649.6 and publication number CN213915201U. The projectile lifting mechanism for the ultrasonic cleaner includes a base plate, a lifting device connected to the base plate, a lifting platform provided by the lifting device, a projectile component connected to the lifting platform, a support plate connected to the upper end of the projectile component, and a tray assembly for carrying a cleaning basket connected to one side of the support plate.

[0004] However, in the ultrasonic cleaning machine's integrated throwing and lifting mechanism, one side of the pallet assembly is connected to the support plate. The throwing motor in the throwing assembly drives the support plate to rise and fall using a long, strip-shaped drive plate, which in turn drives the pallet assembly to rise and fall. During this process, the pallet assembly experiences uneven force on one side, resulting in uneven force distribution across the entire pallet assembly. This uneven force distribution is further exacerbated when a cleaning basket filled with workpieces is placed on the pallet assembly, leading to instability in the lifting and lowering process of the cleaning basket. Especially after long-term use, components such as the pallet assembly are prone to bending, folding, and increased wear, directly affecting the throwing stability and cleaning effect. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an ultrasonic cleaning and throwing device, which solves the problem of uneven force distribution during the lifting and throwing process of existing cleaning baskets.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] An ultrasonic cleaning and agitation device includes a top-open cleaning tank and a driving component. A rotating shaft is rotatably connected within the cleaning tank in a left-right direction. The driving component is connected to the rotating shaft and can drive it to rotate. The device is characterized in that elongated agitation plates are fitted and fixed to the outer sides of both ends of the rotating shaft. The two agitation plates are positioned opposite each other, and their length direction is perpendicular to the axial direction of the rotating shaft. Agitation wheels are rotatably connected to the side portions of both agitation plates. Two opposing brackets are provided within the cleaning tank, each located above the agitation wheels at both ends of the rotating shaft. Each bracket has an opening. When the rotating shaft rotates, the top of at least one agitation wheel at each end of the rotating shaft abuts against the top wall of the corresponding opening. Two sets of guide wheels are rotatably connected to the side walls of the left and right sides of the cleaning tank, and these guide wheels abut against the side walls of the openings of the corresponding brackets.

[0008] When cleaning workpieces, this ultrasonic cleaning and agitation device places a cleaning basket filled with workpieces between two opposing brackets inside the cleaning tank, which support the basket. At the start of cleaning, the drive unit rotates the rotating shaft circumferentially, which in turn causes the agitator plate to drive the agitator wheel to move in a circular motion around the axis of the rotating shaft. The brackets, resting against the agitator wheel, move up and down under the guidance of the guide wheel as the agitator wheel oscillates, thus achieving the agitation.

[0009] In this ultrasonic cleaning and agitation device, the agitation wheels at both ends of the rotating shaft are connected to the sides of two opposing agitation plates. The two brackets, supported by gravity against the agitation wheels, maintain an equal height above their respective wheels. This ensures that the two brackets receive synchronized and uniform force while providing stable support to the bottom of the cleaning basket on both sides, preventing uneven force distribution on the basket placed on the brackets. Furthermore, both the agitation wheels and guide wheels are rotatable, resulting in rolling friction between the brackets and the guide wheels during agitation, reducing wear and ensuring smoother lifting and agitation of the brackets.

[0010] In the aforementioned ultrasonic cleaning and agitation device, the bottom of the bracket is recessed upwards to form the opening. The side walls on both sides of the opening are vertically oriented planes. Each bracket is equipped with four guide wheels, which are divided into two groups, with two guide wheels in each group arranged vertically. These four guide wheels abut against the side walls of the bracket opening, guiding the lifting and lowering of the bracket while preventing it from swaying or swinging radially, thus ensuring the stability of the bracket's lifting and lowering.

[0011] In the aforementioned ultrasonic cleaning and agitation device, several guide wheels have recessed, annular limiting grooves on their outer circumferential surfaces. The sides of the bracket located on either side of the opening are correspondingly engaged within these limiting grooves. These limiting grooves on the outer circumferential surfaces of the guide wheels further limit the radial position of the bracket and also limit its axial position, thus ensuring stability during both the lifting and lowering of the bracket and the agitation of the cleaning basket.

[0012] In the aforementioned ultrasonic cleaning and agitation device, the axes of the two guide wheels in each set of guide wheels are located above and below the axis of rotation, respectively. The top wall of the bracket has an upwardly recessed clearance corresponding to the position of the guide wheels. The axes of the two guide wheels are located above and below the axis of rotation, ensuring that the height of each set of guide wheels is approximately the same as the height of the rotation axis and the agitation wheel. This fully utilizes the space within the cleaning tank, reduces the vertical space occupied, and makes the structure more compact. Furthermore, the clearance prevents the weight of the bracket from being applied to the guide wheels during lifting, allowing the bracket to move stably with the agitation wheel. This reduces space occupation while ensuring the stability of the bracket's movement.

[0013] In the aforementioned ultrasonic cleaning and agitation device, two sets of guide wheels are respectively positioned in front of and behind the rotating shaft. This forms a structure with central drive and two-sided guidance, making the guiding and driving process smoother and also resulting in a more compact structure.

[0014] In the aforementioned ultrasonic cleaning and agitation device, the support frame includes a vertically arranged plate-shaped support plate and four rod-shaped support rods. The opening is located on the support plate, and the axial direction of the four support rods is aligned with the axial direction of the rotation shaft. The four support rods are distributed in an equilateral trapezoidal shape, with the horizontal distance between the two upper support rods being greater than the horizontal distance between the two lower support rods. The vertically arranged support plate reduces the space occupied in the lateral direction within the cleaning tank, and the four support rods can respectively limit the bottom and sides of the cleaning basket in the front-back direction, preventing the cleaning basket from shifting during agitation.

[0015] Compared with existing technologies, this ultrasonic cleaning and agitation device has the following advantages:

[0016] 1. The same rotating shaft drives two brackets to lift and lower synchronously through two ballistic wheels at the left and right ends, so that the bottom of the left and right sides of the cleaning basket is evenly stressed and stably supported. This avoids the situation where the cleaning basket placed on the bracket is unevenly stressed, which would affect the cleaning effect.

[0017] 2. During the throwing process, the bracket is guided by the guide wheel and driven only by the throwing wheel, ensuring that the bracket is not driven by other components other than the throwing wheel during the up and down throwing process, thus further ensuring the stability of the cleaning basket during the lifting process.

[0018] 3. Since both the throwing wheel and the guide wheel can rotate, there is always rolling friction between them during the throwing process of the bracket, which reduces wear and makes the lifting and throwing of the bracket smoother. Attached Figure Description

Detailed Implementation

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1 As shown, this ultrasonic cleaning and agitation device includes a cleaning tank 1 with a square groove open at the top, a rotating shaft 2 in the shape of a round rod, and a driving component 3 capable of driving the rotating shaft 2 to rotate circumferentially. The rotating shaft 2 is horizontally arranged at the bottom of the cleaning tank 1 along the left and right directions, and both ends of the rotating shaft 2 extend out from the left and right sides of the cleaning tank 1, respectively. Bearings are provided between the outer sides of both ends of the rotating shaft 2 and the cleaning tank 1. One end of the rotating shaft 2 is connected to a motor, which is fixed to the outside of the cleaning tank 1 and serves as the driving component 3, through a reduction gearbox.

[0025] like Figure 2 and Figure 3As shown, elongated agitator plates 7 are fitted and fixed to the outer sides of both ends of the rotating shaft 2, and both agitator plates 7 are located inside the cleaning tank 1. The length direction of the two agitator plates 7 is perpendicular to the axial direction of the rotating shaft 2. Agitator wheels 4 are rotatably connected to the sides of both ends of the two agitator plates 7. The four agitator wheels 4 are of the same specification, and the axial direction of the agitator wheels 4 is consistent with the axial direction of the rotating shaft 2. The diameter of the four agitator wheels 4 is larger than the diameter of the rotating shaft 2, and the distance between the axis of the four agitator wheels 4 and the axis of the rotating shaft 2 is the same. The four agitator wheels 4 at both ends of the rotating shaft 2 are arranged opposite each other, that is, in pairs.

[0026] On the left and right sides of the cleaning tank 1, near the two throwing wheels 4, there are brackets 5 and guide wheels 6. Since the structures on both sides of the cleaning tank 1 are the same and are directly opposite each other, the following description will take one side as an example.

[0027] Four guide wheels 6 are rotatably connected to the side wall of the cleaning tank 1. The four guide wheels 6 are arranged in a square pattern, dividing the guide wheels 6 into two groups. Two guide wheels in one group are arranged vertically spaced, and two guide wheels in the other group are also arranged vertically spaced. The height positions of the guide wheels 6 in the two groups are the same. The axial direction of the four guide wheels 6 is consistent with the axial direction of the rotating shaft 2.

[0028] In this embodiment, two sets of guide wheels 6 are respectively disposed in front of and behind the rotating shaft 2, that is, the rotating shaft 2, the projectile plate 7, and the projectile wheel 4 are all disposed between the two sets of guide wheels 6; the axes of the two guide wheels 6 in each set of guide wheels 6 are respectively located above and below the axis of the rotating shaft 2. Preferably, the midpoint of the line connecting the axes of the two guide wheels 6 in each set of guide wheels 6 is at the same height as the axis of the rotating shaft 2; as the projectile wheel 4 rotates with the rotating shaft 2, the outer circumferential surface of the projectile wheel 4 can rotate to be simultaneously higher than the four guide wheels 6, and can also be simultaneously lower than the four guide wheels 6. A circular limiting groove 6a is provided on the outer circumferential surface of the four guide wheels 6, and the bottom surface of the limiting groove 6a is an arc surface.

[0029] The bracket 5 is positioned above the throwing wheel 4 and includes a vertically arranged flat plate 5c and four round rods 5d. The axial direction of the four rods 5d is consistent with the axial direction of the rotating shaft 2. The four rods 5d are distributed in an equilateral trapezoidal shape, and the horizontal distance between the two upper rods 5d is greater than the horizontal distance between the two lower rods 5d.

[0030] The bottom of the tray 5c has an upwardly recessed opening 5a, which is roughly square and extends through the tray 5c in the left-right direction. The front and rear side walls of the opening 5a are vertically oriented planes, and the side walls of the opening 5a respectively fit into the limiting grooves 6a of the four guide wheels 6 and abut against the four guide wheels 6 simultaneously. The top wall of the opening 5a of the tray 5c has an upwardly recessed clearance opening 5b corresponding to the position of the guide wheel 6, and at least one of the two projectile wheels 4 abuts against the top wall of the opening 5a.

[0031] When cleaning workpieces, this ultrasonic cleaning and agitation device places a rectangular cleaning basket filled with workpieces into the cleaning tank 1, such that the bottom surface of the four corners of the cleaning basket abuts against the four lower support rods 5d on the two brackets 5. Simultaneously, the front and rear sides of the cleaning basket abut against or are adjacent to the four higher support rods 5d. The eight support rods 5d on the brackets 5 limit the lower and front-rear positions of the cleaning basket, while the support plate 5c on the brackets 5 limits the left-right position of the cleaning basket.

[0032] When cleaning begins, the drive unit 3 drives the rotating shaft 2 to rotate circumferentially. Then, the four throwing wheels 4 connected to the outer sides of both ends of the rotating shaft 2 make circular motion around the axis of the rotating shaft 2. Under the action of gravity, the bracket 5, which is against the throwing wheel 4, can move up and down under the guidance of the guide wheel 6 as the throwing wheel 4 swings, thus realizing the throwing motion.

[0033] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
