Description

Technical Field

[0001] This utility model relates to ultrasonic cleaning machines, and more particularly to heavy-duty agitation devices in ultrasonic cleaning machines. Background Technology

[0002] With industrial development, the requirements for cleaning are becoming increasingly stringent. In cleaning operations, to achieve better cleaning results, ultrasonic cleaners are usually used in conjunction with agitation mechanisms for powerful cleaning. However, the agitation mechanisms currently on the market generally use chain drive mechanisms, gear drive mechanisms, or telescopic rod structures to drive the cleaning basket to rise and fall. These mechanisms not only have poor stability but also insufficient strength, resulting in a small load capacity and an inability to support excessively heavy materials, thus limiting their application scenarios. Utility Model Content

[0003] The purpose of this invention is to provide a heavy-duty throwing device for an ultrasonic cleaner that is structurally stable, has a high load capacity, and allows for easy adjustment of the lifting height.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a heavy-duty agitation device in an ultrasonic cleaner, comprising: a fixed frame surrounding and connected to the ultrasonic cleaner; a three-axis commutator at each of the left and right ends of the fixed frame; a main shaft connecting the two three-axis commutators to a driven sprocket; a servo reduction motor on the fixed frame; a drive sprocket on the servo reduction motor; a transmission chain between the drive sprocket and the driven sprocket; and auxiliary shafts connected to both the front and rear ends of the three-axis commutators. The upper part is equipped with a first bearing seat, which is fixed on the fixed frame. A swing arm is inserted into the secondary rotating shaft, and a support shaft is inserted into the swing arm. A heavy-duty bearing is mounted on the support shaft. The throwing bracket abuts against the heavy-duty bearing. Four guide shafts are vertically arranged around the throwing bracket. Four mounting plates are arranged around the fixed frame. A linear bearing is set at the upper and lower ends of each mounting plate. The guide shaft slides through two linear bearings on the mounting plate on the same side. Several cleaning baskets are arranged at intervals on the throwing bracket. The number of cleaning baskets is the same as the number of water tanks in the ultrasonic cleaner.

[0005] Furthermore, in the aforementioned heavy-duty agitation device of the ultrasonic cleaner, two three-axis commutators are respectively connected to a main shaft via a first coupling. A second bearing seat is fitted on the main shaft and fixed to a fixed frame. A connecting sleeve is fitted between the two main shafts. A first square shaft is provided at the close ends of the two main shafts. A square through hole is provided in the connecting sleeve. The first square shaft on the main shaft is inserted into the square through hole of the connecting sleeve. A driven sprocket is fitted on the connecting sleeve and connected by a key. A set bolt is threaded onto the driven sprocket and abuts against the connecting sleeve.

[0006] Furthermore, in the aforementioned heavy-duty agitation device of the ultrasonic cleaner, both the passive sprocket and the active sprocket are double-row sprockets, and two transmission chains are arranged between the passive sprocket and the active sprocket.

[0007] Furthermore, in the aforementioned heavy-duty agitation device of the ultrasonic cleaner, the secondary rotating shaft is connected to the three-axis commutator via a second coupling. The connection structure between the secondary rotating shaft, the swing arm, and the support shaft is as follows: two square countersunk holes are provided on the swing arm, which are located at both ends of the swing arm and not on the same side. A second square shaft is provided on both the secondary rotating shaft and the support shaft. After the second square shafts of the secondary rotating shaft and the support shaft are inserted into the corresponding square countersunk holes, they are connected to the swing arm via countersunk bolts.

[0008] Furthermore, in the aforementioned ultrasonic cleaning machine, the heavy-duty agitation device has two heavy-duty bearings mounted on each support shaft. The two heavy-duty bearings are placed together, and two locking nuts are placed together and then abut against the heavy-duty bearings.

[0009] Furthermore, in the aforementioned heavy-duty agitation device of the ultrasonic cleaner, the agitation bracket includes: an upper rectangular beam and a lower rectangular beam, the upper and lower rectangular beams are connected by four columns, the lower rectangular beam abuts against a heavy-duty bearing, the cleaning basket is mounted on the upper rectangular beam, and optical axis support seats are provided around the upper and lower rectangular beams. The optical axis support seats on the upper and lower rectangular beams are aligned vertically, and the upper and lower ends of the guide shaft are respectively inserted into the two vertically aligned optical axis support seats and abut against the upper and lower rectangular beams.

[0010] The advantages of this invention are as follows: the rigid frame structure of the throwing bracket improves its stability; the four guide shafts on the throwing bracket and the linear bearings on the four mounting plates of the fixed frame form a sliding pair, enabling the throwing bracket to have a stronger static load-bearing capacity and to carry heavier materials; the connection between the secondary rotating shaft, swing arm, and support shaft through the square countersunk hole and the second square shaft insertion structure improves the connection strength between the secondary rotating shaft, swing arm, and support shaft, enabling them to withstand higher loads and throw heavier materials when used with an ultrasonic cleaner; the heavy-duty bearing has a high rated dynamic and static load, and when carrying heavier materials, the heavy-duty bearing can withstand the periodic impact load generated by the high-load throwing bracket during movement, ensuring the stability of the overall structure; the transmission chain between the active sprocket and the passive sprocket is not directly affected by the weight of the throwing bracket and the materials in the cleaning basket within it, reducing the load on the transmission chain and ensuring its service life and stability; when it is necessary to replace the heavy-duty bearing or swing arm, it is only necessary to lift the throwing bracket upwards to detach it from the heavy-duty bearing for replacement, which is convenient and quick.

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] like Figures 1-4 As shown, the heavy-duty agitation device in the ultrasonic cleaner of this utility model includes: a fixed frame 2 surrounding and connected to the ultrasonic cleaner 1; a three-axis commutator 3 at each of the left and right ends of the fixed frame 2; each of the two three-axis commutators 3 being connected to a main rotating shaft 32 via a first coupling 31; a second bearing seat 321 mounted on the main rotating shaft 32 and fixed to the fixed frame 2; a connecting sleeve 33 between the two main rotating shafts 32; a first square shaft 322 at the close ends of the two main rotating shafts 32; a square through hole 331 in the connecting sleeve 33; and the first square shaft 322 on the main rotating shaft 32 being inserted into the square through hole 331 of the connecting sleeve 33. A passive sprocket 34 is fitted onto the sleeve 33 and connected by a key. A set bolt 341 is threaded onto the passive sprocket 34 and abuts against the connecting sleeve 33. A servo geared motor 21 is mounted on the fixed frame 2, and a drive sprocket 211 is mounted on the servo geared motor 21. A transmission chain 22 is provided between the drive sprocket 211 and the passive sprocket 34. In this embodiment, both the drive sprocket 211 and the passive sprocket 34 are double-row sprockets. Two transmission chains 22 are provided between the passive sprocket 34 and the drive sprocket 211. The main shaft 32 and the connecting sleeve 33 are connected by an insertion structure between a square through hole 331 and a first square shaft 322, which facilitates connection and improves the connection strength between the main shaft 32 and the connecting sleeve 33.

[0017] Both ends of the three-axis commutator 3 are connected to secondary shafts 36 via second couplings 35. A first bearing housing 361 is mounted on the secondary shaft 36 and fixed to the mounting bracket 2. A swing arm 4 is mounted on the secondary shaft 36, and a support shaft 41 is mounted on the swing arm 4. Two heavy-duty bearings 42 are mounted on the support shaft 41 and are placed close together. Two locking nuts 411 are threaded onto the support shaft 41. After being brought together, they rest against the heavy-duty bearing 42. In this embodiment, the connection structure between the secondary rotating shaft 36, the swing arm 4, and the support shaft 41 is as follows: two square countersunk holes 43 are provided on the swing arm 4. The two square countersunk holes 43 are located at both ends of the swing arm 4 and are not on the same side. A second square shaft 44 is provided on both the secondary rotating shaft 36 and the support shaft 41. The second square shaft 44 of the secondary rotating shaft 36 and the support shaft 41 are inserted into the corresponding square countersunk holes 43 and then connected to the swing arm 4 by countersunk bolts 45.

[0018] The projectile support 5 rests against heavy-duty bearings 42 around its perimeter. These bearings have high rated dynamic and static loads, capable of withstanding the periodic impact loads generated during the projectile support 5's movement. The projectile support 5 includes an upper rectangular beam 51 and a lower rectangular beam 52, connected by four columns 53. The lower rectangular beam 52 rests against the heavy-duty bearings 42. The rigid frame structure of the projectile support 5 enhances its resistance to deformation, providing stable support for dynamic loads. A cleaning basket 6 is mounted on the upper rectangular beam 51. The number of cleaning baskets 6 is the same as the number of water tanks in the ultrasonic cleaner 1. The connection structure between the cleaning baskets 6 and the upper rectangular beam 51 is existing technology and will not be described in detail here. Optical shaft support seats 54 are provided around both the upper and lower rectangular beams 51. The optical axis support seat 54 on the rectangular beam 51 and the optical axis support seat 54 on the lower rectangular beam 52 are aligned vertically. A guide shaft 55 is installed between the two vertically aligned optical axis support seats 54. The upper and lower ends of the guide shaft 55 abut against the upper rectangular beam 51 and the lower rectangular beam 52, respectively. Four mounting plates 23 are arranged around the fixed frame 2. A linear bearing 231 is installed at the upper and lower ends of the mounting plate 23. The guide shaft 55 slides through the two linear bearings 231 on the same side of the mounting plate 23. The four guide shafts 55 and the linear bearings 231 on the mounting plate 23 form a sliding pair, which evenly distributes the weight of the throwing bracket 5 and the cleaning basket 6 to four independent support points, greatly reducing the risk of stress concentration at a single point, making the overall structure have a stronger static load-bearing capacity, and effectively suppressing the additional torque caused by lateral displacement.

[0019] In use, the cleaning basket 6, containing the material to be cleaned, is installed on the throwing bracket 5 and then immersed in the water tank. The ultrasonic cleaner 1 is started, and the cleaning solution in the water tank cleans the material to be cleaned. The servo reduction motor 21 drives the active sprocket 211 to drive the passive sprocket 34 to rotate through the transmission chain 22. The passive sprocket 34 drives the two main rotating shafts 32 to rotate through the connecting sleeve 33. The two main rotating shafts 32 drive the corresponding auxiliary rotating shafts 36 to rotate through their respective connected three-axis commutator 3. The auxiliary rotating shafts 36 drive the swing arm 4 and the components on the swing arm 4. The support shaft 41 rotates up and down, and the heavy-duty bearing 42 on the support shaft 41 also rotates up and down. When the heavy-duty bearing 42 rotates upward, it pushes the throwing bracket 5 upward. When the heavy-duty bearing 42 rotates downward, the throwing bracket 5 descends along with the heavy-duty bearing 42 under its own weight. During the lifting and lowering process, the throwing bracket 5 can drive the cleaning basket 6 to rise and fall in the water tank. During the lifting and lowering process, the cleaning basket 6 can fully contact the object to be cleaned with the cleaning liquid, and the dirt on the surface of the object to be cleaned can be quickly peeled off under the action of external force, thereby improving the cleaning efficiency. During use, the swing arm 4, support shaft 41, and heavy-duty bearing 42 are the main load-bearing components of the throwing bracket 5. The swing arm 4 and support shaft 41, and the support shaft 41 and auxiliary rotating shaft 36 are connected by a square countersunk hole 43 and a second square shaft 44 through an insertion structure. This improves the connection strength and allows it to withstand higher loads. Four sets of linkage mechanisms composed of the swing arm 4, support shaft 41, and auxiliary rotating shaft 36 are set around the fixed frame 2 to support the throwing bracket 5. This divides the weight of the throwing bracket 5 into four parts. The transmission chain 22 between the drive sprocket 211 and the driven sprocket 34 only needs 1 / 4 of the original force to drive the linkage mechanism composed of the swing arm 4, support shaft 41, and auxiliary rotating shaft 36 to raise and lower the throwing bracket 5, reducing the load on the transmission chain 22 and improving the service life and stability of the transmission chain 22. During prolonged use, the heavy-duty bearing 42 is prone to damage and needs to be replaced in time. When replacing the heavy-duty bearing 42, simply lift the throwing bracket 5 upwards to detach it from the heavy-duty bearing 42, and the heavy-duty bearing 42 can be replaced directly. This is convenient and quick. When cleaning items of different sizes, it is necessary to adjust the lifting stroke of the throwing bracket 5. The lifting stroke of the throwing bracket 5 is directly related to the length of the swing arm 4. In this case, simply lift the throwing bracket 5 upwards to detach it from the heavy-duty bearing 42 and replace the swing arm 4 with one of the appropriate length.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
