Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic cleaning machines, in particular to a loading and unloading device for ultrasonic cleaning machines. Background Art

[0002] An ultrasonic cleaner is a machine used to clean the surfaces of hardware and plastic parts. It primarily consists of an ultrasonic generator circuit and an ultrasonic transducer. The ultrasonic transducer is a sandwich-type transducer made of lead zirconate titanate piezoelectric ceramic material. Piezoelectric ceramic material undergoes dimensional changes under the influence of an electric field. Under the influence of an alternating electric field, the transducer generates mechanical vibrations, which propagate into the cleaning fluid and create tiny bubbles. These bubbles rapidly expand and contract in the liquid, generating high-intensity pressure waves that separate dirt and impurities adhering to the surface. The high-frequency vibrations and pressure waves in the cleaning fluid help remove deposits and reach hard-to-reach areas such as cracks and holes in the surface.

[0003] When using an existing ultrasonic cleaning machine, a material frame full of workpieces to be cleaned is placed into a cleaning tank and taken out after cleaning. This process requires a lot of manual intervention. For some heavier metal products, manual operation is more laborious, which reduces the cleaning efficiency. Utility Model Content

[0004] The main purpose of the utility model is to provide a loading and unloading device for an ultrasonic cleaning machine.

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0021] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0022] like Figures 1-4 As shown, this embodiment provides a loading and unloading device for an ultrasonic cleaning machine, including a cleaning box 1, with a loading conveyor frame 2 and a unloading conveyor frame 3 provided on both sides of the outside of the cleaning box 1; a feeding mechanism frame 4 is provided directly above the cleaning box 1, and the feeding mechanism frame 4 includes a feeding plate 5, a driving chain belt 13, a fixed shaft 16, a joint connecting rod 15 and a driving wheel 14.

[0023] The loading conveyor rack 2 is flush with the inclined surface of the inner wall of the cleaning box 1, and the unloading conveyor rack 3 is lower than the inclined surface of the inner wall of the cleaning box 1. A material frame 6 is slidably placed on the loading conveyor rack 2. The material frame 6 is a structure with hollowed-out edges. When loading, a top space is reserved to facilitate the entry of the feeding plate 5 to push the inner and outer walls of the material frame 6.

[0024] The driving chain belt 13 is slidably set in the chain belt groove 12, the driving wheel 14 is engaged with the driving chain belt 13, and a supporting wheel 17 is also engaged at the bottom of the driving chain belt 13. The driving chain belt 13 can be limited in the chain belt groove 12.

[0025] One end of the fixed shaft 16 is inserted into the inner wall of the driving chain belt 13, and the fixed shaft 16 is slidingly connected to the outer wall of the chain belt groove 12. The joint connecting rod 15 is rotatably connected to the fixed shaft 16. The joint connecting rod 15 can simulate the force exerted by the human joint when turning, and the support feeding plate 5 can hard push the material frame 6 to move.

[0026] The feed plate 5 and one end of the outside of the fixed shaft 16 are detachably mounted, and an operation panel 7 is embedded in one side wall of the outside of the cleaning box 1. The internal wires of the operation panel 7 are connected to the ultrasonic generating circuit 9. The top of the ultrasonic generating circuit 9 is cooperated with an ultrasonic transducer 8 installed in contact with the inner wall of the cleaning box 1. The ultrasonic generating circuit 9 is used to generate a high-frequency and high-voltage alternating current signal, and the ultrasonic transducer 8 converts the alternating current signal into mechanical energy.

[0027] A feeding motor 11 is installed on the outside of the driving wheel 14, a sliding roller 18 is laid on the bottom of the inner wall of the cleaning box 1, and a leakage reflux groove 10 connected to the inside of the cleaning box 1 is fixed at the bottom of the unloading conveying frame 3. The feeding motor 11 can control the speed through the operation panel 7, thereby adjusting the cleaning time of the items in the material frame 6 in the cleaning pool.

[0028] The working principle of this device:

[0029] Step 1: Connect the external power supply, connect the loading and unloading conveyor frame 2 and the unloading conveyor frame 3 to the external driving mechanism respectively, and manually place the workpiece to be washed into the material frame 6 at the input end of the loading and unloading conveyor frame 2, and the height of the workpiece to be placed is the set height, which does not affect the operation of the feeding plate 5;

[0030] Step 2: After the material frame 6 moves to the bottom of the feeding plate 5, the feeding plate 5 enters the material frame 6, and the material frame 6 continues to move and enters the inclined table. Under the action of gravity, it slides on the sliding roller 18. However, at this time, the feeding plate 5 enters the interior of the material frame 6, which can limit the material frame 6 from sliding down into the cleaning tank at a very fast speed, so that the feeding plate 5 can slowly feed the material frame 6 into the cleaning tank of the cleaning box 1, and on the sliding roller 18 at the bottom of the cleaning tank, the feeding plate 5 is driven by the feeding mechanism to continue to move forward;

[0031] Step 3: After the material frame 6 moves to the bottom of another slope of the cleaning box 1, the material is pulled and moved, and the material frame 6 slides up along the sliding roller 18, and finally falls out from the top of the slope and enters the feeding conveyor rack. Since the height of the feeding conveyor rack is lower than the slope table, the feeding plate 5 and the material frame 6 can be separated, and the liquid in the material frame 6 re-enters the cleaning tank from the leakage reflux groove, completing a cleaning cycle.

[0032] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention based on the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
