Description

Technical Field

[0001] The invention belongs to the technical field of ultrasonic cleaning machines, in particular to an upper and lower working station drum type ultrasonic cleaning machine. Background Art

[0002] Ultrasonic cleaning machine is a kind of equipment that uses ultrasonic technology for cleaning. It is widely used in laboratories, medical, electronics and metal processing industries. The ultrasonic generator inside the ultrasonic cleaning machine is used to emit ultrasonic waves into the cleaning machine. When the ultrasonic waves propagate through the liquid medium inside the cleaning rack, their rapid vibrations will form tiny bubbles in the liquid. These bubbles will rapidly increase in the negative pressure stage of the ultrasonic wave and quickly close or collapse in the positive pressure stage. The high temperature and high pressure generated when the bubbles collapse can penetrate the tiny gaps on the surface of the object, decompose and peel off the pollutants, so that the cleaning liquid can enter every corner of the object, ensuring that the cleaning liquid can fully contact the dirt. At the same time, the ultrasonic wave can also destroy the adhesion between the pollutants and the surface of the object, and promote the separation of the dirt.

[0003] The cleaning drum of the existing upper and lower station drum-type ultrasonic cleaning machine rolls inside the cleaning box. When cleaning parts, the flip cover on the surface of the cleaning drum is generally fixed to the surface of the cleaning drum by a hook.

DETAILED DESCRIPTION

[0023] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0024] like Figure 1-6 As shown, the present invention provides a technical solution: an upper and lower station drum-type ultrasonic cleaning machine, comprising an installation base plate 1, universal wheels 2 are fixedly installed at the four corners of the bottom of the installation base plate 1, a cleaning box 3 is fixedly installed on the top of the installation base plate 1, two groups of cleaning tanks 301 are arranged inside the cleaning box 3, a drainage tank 302 is arranged at the bottom of the cleaning tank 301, two groups of drainage valves 303 are arranged on one side of the cleaning box 3, and the drainage valve 303 is connected with the drainage tank 302. By providing the drainage tank 302 and the drainage valve 303, the cleaning liquid inside the cleaning tank 301 needs to be replaced regularly after a certain period of use, and the drainage valve 303 is opened to allow the cleaning liquid inside the cleaning tank 301 to pass through the drainage tank 302 and be concentrated to the drainage valve 303 to be discharged from the cleaning tank 301.

[0025] Two sets of ultrasonic generators 4 are fixedly mounted on the surface of one side of the cleaning box 3. Since the ultrasonic generators 4 are provided, the ultrasonic generators 4 are controlled to emit ultrasonic waves toward the inside of the cleaning tank 301, so that the ultrasonic waves propagate in the cleaning liquid inside the cleaning tank 301, thereby cleaning the parts inside the cleaning drum 6;

[0026] Two groups of mounting turntables 5 are symmetrically and rotatably installed on both sides of the inside of the cleaning box 3, and four groups of mounting turntables 5 are located inside the cleaning box 3 opposite to each other. Positioning slots 501 are symmetrically provided on one side of the mounting turntable 5, and connecting studs 502 are symmetrically and rotatably installed on both sides of the mounting turntable 5. Fixing nuts 503 are provided on the surfaces of the connecting studs 502. By providing the mounting turntable 5, after the cleaning roller 6 is clamped and fixed between the two groups of opposite mounting turntables 5, the cleaning roller 6 can rotate inside the cleaning box 3.

[0027] A cleaning drum 6 is provided inside the cleaning box 3 between two sets of opposite mounting turntables 5. A flip cover plate 601 is rotatably installed on the surface of the cleaning drum 6. A fixed clamping strip 602 is fixedly installed on one side of the flip cover plate 601. Due to the provision of the flip cover plate 601, the flip cover plate 601 is clamped and fixed on the surface of the cleaning drum 6 to ensure that the parts inside the cleaning drum 6 will not fly out when the cleaning drum 6 rotates.

[0028] The two sides of the cleaning drum 6 are symmetrically fixed with connecting end plates 603, and the side of the connecting end plate 603 away from the cleaning drum 6 is symmetrically fixed with a fixing block 604, and the position of the fixing block 604 corresponds to the position of the connecting stud 502. By providing the fixing block 604 and the connecting stud 502, after the connecting end plate 603 is pressed against the surface of the mounting turntable 5 so that the position of the fixing block 604 corresponds to the position of the connecting stud 502, the connecting stud 502 is rotated so that the connecting stud 502 is inserted into the corresponding slot on the surface of the fixing block 604, and the fixing nut 503 is tightened to press against the fixing block 604, so that the connecting end plate 603 is connected and fixed to the mounting turntable 5;

[0029] The connecting end plate 603 is located between the two groups of fixed blocks 604 and is symmetrically fixed with a positioning strip 605. The positioning strip 605 corresponds to the position of the positioning slot 501 and has the same shape. Because the positioning slot 501 and the positioning strip 605 are provided, after the positioning slot 501 is stuck on the surface of the corresponding positioning strip 605, it is ensured that the connecting end plate 603 will not be misaligned when it is stuck on one side of the mounting turntable 5, and at the same time, it is ensured that the connecting end plate 603 will not be misaligned or deflected when it rotates with the mounting turntable 5.

A trapezoidal clamping strip 703 is slidably installed inside the concave mounting frame 701, and the position of the trapezoidal clamping strip 703 corresponds to the position of the fixed clamping strip 602. Limiting protrusions 704 are symmetrically fixedly installed at both ends of the trapezoidal clamping strip 703, and the limiting protrusions 704 correspond to the position of the limiting slide grooves 702. By providing the limiting slide grooves 702 and the limiting protrusions 704, the trapezoidal clamping strip 703 is pushed to slide inside the concave mounting frame 701, and the limiting protrusions 704 are driven to slide inside the corresponding limiting slide grooves 702, to ensure that the trapezoidal clamping strip 703 will not separate from the concave mounting frame 701.

[0031] The cam 708 is a substantially parallelogram of the cam 709 and the engagement of the cam 709 with the engagement of the cam 709. The cam 709 is a substantially parallelogram of the cam 709 and the engagement of the cam 709 with the cam 709. The cam 708 is a substantially parallelogram of the cam 709 and the engagement of the cam 709 with the cam 709.

[0032] A mounting groove 709 is provided at the central position of one side of the trapezoidal clamping strip 703 close to the concave mounting frame 701, and an adjusting stud 710 is slidably installed inside the mounting groove 709, and one end of the adjusting stud 710 passes through the mounting groove 709 and is fixedly connected to the inner wall of the concave mounting frame 701, and an adjusting screw sleeve 711 is provided on the surface of the adjusting stud 710 located between the trapezoidal clamping strip 703 and the concave mounting frame 701. By providing the adjusting screw sleeve 711, after the trapezoidal clamping strip 703 is inserted into the fixed clamping strip 602, the adjusting screw sleeve 711 is twisted to move on the surface of the adjusting stud 710 until the adjusting screw sleeve 711 is tightly attached to the surface of the trapezoidal clamping strip 703, ensuring that the trapezoidal clamping strip 703 is stuck in the fixed clamping strip 602 and will not detach at will.

The rotating mechanism 8 comprises a mounting base 801, a rotating motor 802 is fixedly mounted on the top of the mounting base 801, a first transmission wheel 803 is fixedly mounted at the output end of the rotating motor 802, two groups of transmission belts 804 are provided on the surface of the first transmission wheel 803, two groups of second transmission wheels 805 are provided inside the transmission belts 804, and the second transmission wheels 805 are fixedly connected to the mounting turntable 5 at one side of the cleaning box 3. Since the transmission belts 804 are provided, after the transmission belts 804 are sleeved on the surfaces of the first transmission wheel 803 and the two groups of second transmission wheels 805, the rotating motor 802 is started to drive the first transmission wheel 803 to rotate, and under the friction between the first transmission wheel 803 and the transmission belts 804, the two groups of second transmission wheels 805 are driven to rotate synchronously, so that the two groups of cleaning rollers 6 inside the cleaning box 3 rotate synchronously.

[0034] The working principle of the present invention is:

[0035] Open the flip cover 601, put an appropriate amount of parts into the cleaning drum 6, turn the adjusting screw sleeve 711 away from the trapezoidal clip 703, so that the trapezoidal clip 703 can slide inside the concave mounting frame 701, turn the flip cover 601 to close on the surface of the cleaning drum 6, so that one side of the flip cover 601 slides through the trapezoidal clip 703, and the trapezoidal clip 703 slides inside the concave mounting frame 701 under the rebound effect of the lifting spring 708, ensuring that the trapezoidal clip 703 can be pushed out of the concave mounting frame 701 and inserted into the fixed clip 602, turn the adjusting screw sleeve 711 to fit the trapezoidal clip 703, and clamp and fix the trapezoidal clip 703 to ensure that the trapezoidal clip 703 is stuck in the fixed clip 602 and will not fall off at will;

[0036] Adjust the two sets of mounting turntables 5 opposite to each other inside the cleaning box 3 so that the positioning slots 501 on one side of the mounting turntables 5 are vertically upward, and the cleaning roller 6 with an appropriate amount of parts is vertically inserted between the two sets of mounting turntables 5 opposite to each other, so that the positioning clips 605 on the surfaces of the connecting end plates 603 on both sides of the cleaning roller 6 are vertically inserted into the corresponding positioning slots 501 until the positions of the fixing clips 604 and the connecting studs 502 are corresponding, and after the connecting studs 502 are rotated to be inserted into the surfaces of the fixing clips 604, tighten the fixing nuts 503 to be tightly attached to the surfaces of the fixing clips 604, so that the connecting end plates 603 and the mounting turntables 5 are connected and fixed, and repeat the steps to clamp and fix another set of cleaning rollers 6 between the mounting turntables 5 corresponding to the inner walls of another set of cleaning tanks 301;

[0037] Pour a proper amount of cleaning liquid into the two groups of cleaning tanks 301 to ensure that the cleaning liquid can cover the parts inside the cleaning drum 6, put the two groups of transmission belts 804 on the corresponding surfaces of the first transmission wheel 803 and the second transmission wheel 805, start the rotating motor 802 to control the first transmission wheel 803 to rotate, and under the friction between the inner wall of the transmission belt 804 and the surfaces of the first transmission wheel 803 and the second transmission wheel 805, drive the mounting turntable 5 to rotate, so that the cleaning drums 6 inside the two groups of cleaning tanks 301 rotate synchronously, and at the same time control the ultrasonic generator 4 to emit ultrasonic waves to impact the cleaning liquid inside the cleaning tank 301, so that the cleaning liquid inside the cleaning tank 301 oscillates, and the parts inside the cleaning drum 6 are cleaned. At the same time, when the cleaning drum 6 rotates inside the cleaning tank 301, it is ensured that the parts inside the cleaning drum 6 can be fully cleaned.
