[0002] Double-row sprocket is a common mechanical transmission element, connected by two parallel chains, with stable transmission performance and high load capacity, widely used in various mechanical equipment and industrial fields, and the larger pitch double-row sprocket is a special sprocket design, which is used in conjunction with the double-pitch chain. The double-pitch chain refers to doubling the pitch of the standard chain, but other parameters remain unchanged. Due to the longer pitch, this design can adapt to longer chain lengths and greater load requirements. In the production process of larger pitch double-row sprockets, in order to remove oil and impurities on their surface, they are usually processed using a cleaning device.

[0003] However, nowadays, the common double-row sprocket cleaning method is often to use a water spray structure in combination with a cleaning roller brush to brush the surface of the double-row sprocket. However, due to the gaps between the bristles of the roller brush itself and the convex teeth on the surface of the double-row sprocket, it is difficult to fully brush the double-row sprocket, and cleaning dead corners are easily produced, resulting in poor cleaning effect of the double-row sprocket. For this reason, we proposed a processing device for larger pitch double-row sprockets. Summary of the invention

At this time, the liquid inlet valve is closed, the air exhaust valve 92 is opened, the air exhaust pump 93 is started, and the air exhaust pipe 91 is used to evacuate the interior of the double-row sprocket cleaning box 1, so that the interior of the double-row sprocket cleaning box 1 is in a vacuum environment, and then the ultrasonic generator 10 is turned on to generate ultrasonic waves, so that the larger pitch double-row sprocket immersed in the cleaning liquid can be ultrasonically cleaned, effectively preventing the occurrence of cleaning dead corners, thereby improving the cleaning effect of the surface of the larger pitch double-row sprocket.

[0022] The rotating tube 4 is movably sleeved in the middle of the sealing cover 2, and a driving assembly 5 is arranged outside the top of the rotating tube 4, and the driving assembly 5 includes a driving motor 51, and the driving motor 51 is fixedly connected to the top of the sealing cover 2, and a driving gear 52 is fixedly sleeved on the output shaft of the driving motor 51, and the outside of the driving gear 52 is meshedly connected with a driven gear 53, and the driven gear 53 is fixedly sleeved on the outside of the top of the rotating tube 4, and the outside of the driving motor 51 is fixedly connected to the top of the sealing cover 2 through a mounting plate, and the thickness of the driven gear 53 is greater than the thickness of the driving gear 52; In this embodiment, when the larger pitch double-row sprocket is being ultrasonically cleaned, the drive motor 51 is turned on to rotate the driving gear 52 and the driven gear 53, and the driven gear 53 drives the rotating tube 4 to rotate, and the rotating tube 4 drives the larger pitch double-row sprocket fixed thereon to rotate, so that the dirt cleaned off the surface of the larger pitch double-row sprocket can fall off quickly, thereby further improving the cleaning effect of the larger pitch double-row sprocket.

The top of the rotating shaft 132 and the middle of the bottom end of the turntable 134 are perpendicular to each other, and there is no contact between the turntable 134 and the support plate 131; In this embodiment, when the larger pitch double-row sprocket fixed on the rotating tube 4 moves up to the top of the double-row sprocket cleaning box 1, the forward and reverse motors 133 are turned on, causing the rotating shaft 132 to rotate 180 degrees, and the rotating shaft 132 will drive the turntable 134 to rotate, prompting the electric push rod 122 on the turntable 134 to drive the sealing cover 2 fixed on the cross plate 121 to rotate 180 degrees. At this time, the rotating tube 4 and the larger pitch double-row sprocket on the sealing cover 2 will also rotate, so that the removed larger pitch double-row sprocket is moved away from the top of the double-row sprocket cleaning box 1, and the electric push rod 122 is started again to cause it to retract, and the electric push rod 122 will use the cross plate 121 to drive the sealing cover 2 to move downward, so that the larger pitch double-row sprocket on the rotating tube 4 that has been cleaned will also move downward, thereby facilitating the subsequent disassembly of the cleaned larger pitch double-row sprocket.

[0031] The working principle and use process of the present invention are as follows: first, the liquid inlet valve is opened to allow the cleaning liquid to flow into the inside of the double-row sprocket cleaning box 1 along the liquid inlet pipe 3, so that the cleaning liquid can submerge the large-pitch double-row sprocket body on the rotating tube 4, then the liquid inlet valve is closed, the air extraction valve 92 is opened, the air extraction pump 93 is started, and the inside of the double-row sprocket cleaning box 1 is vacuumed by using the air extraction pipe 91, so that the inside of the double-row sprocket cleaning box 1 is in a vacuum environment, and then the ultrasonic generator 10 is turned on to generate ultrasonic waves, so that the large-pitch double-row sprocket immersed in the cleaning liquid can be ultrasonically cleaned; Then, the driving motor 51 is turned on, so that the driving gear 52 and the driven gear 53 rotate, and the driven gear 53 drives the rotating tube 4 to rotate, and the rotating tube 4 drives the larger double-row sprocket fixed thereon to rotate, so that the dirt cleaned from the surface of the larger double-row sprocket can fall off quickly, thereby further improving the cleaning effect of the larger double-row sprocket; Then, when the cleaning of the larger double-row sprocket is completed, the drain valve is opened so that the sewage inside the double-row sprocket cleaning box 1 can be discharged along the drain pipe 11, and after the sewage is discharged, the driving assembly 5 is continued to be used to drive the larger double-row sprocket fixed on the rotating tube 4 to rotate, and the air intake valve is opened at the same time, so that the hot air can flow into the interior of the rotating tube 4 along the air intake pipe 8, so that the hot air can be ejected from the through hole 7, so that the cleaned larger double-row sprocket can be quickly dried; Secondly, the electric push rod 122 is started to extend, and the electric push rod 122 drives the cross plate 121 to move vertically upward, and the cross plate 121 drives the sealing cover 2 to move upward, so that the sealing cover 2 and the double-row sprocket cleaning box 1 are separated, and the sealing cover 2 continues to move upward, and drives the larger pitch double-row sprocket fixed on the rotating tube 4 to move out of the double-row sprocket cleaning box 1; Finally, the forward and reverse motor 133 is turned on to make the rotating shaft 132 rotate 180 degrees, and the rotating shaft 132 will drive the turntable 134 to rotate, prompting the electric push rod 122 on the turntable 134 to drive the sealing cover 2 fixed on the cross plate 121 to rotate 180 degrees. At this time, the rotating tube 4 and the larger pitch double-row sprocket on the sealing cover 2 will also rotate, so that the removed larger pitch double-row sprocket is moved away from the top of the double-row sprocket cleaning box 1, and the electric push rod 122 is started again to make it retract, and the electric push rod 122 will use the cross plate 121 to drive the sealing cover 2 to move downward, so that the larger pitch double-row sprocket on the rotating tube 4 that has been cleaned will also move downward, thereby facilitating the subsequent disassembly of the cleaned and dried larger pitch double-row sprocket.
