Description

Technical Field

[0001] The present invention relates to the technical field of transmission shaft cleaning, in particular to cleaning equipment in a transmission shaft production line. Background Art

[0002] In industrial production, the cleanliness of the drive shaft has a vital impact on its performance and service life. Common cleaning methods include spraying and ultrasonic cleaning. For example, a drive shaft cleaning device with patent publication number CN221869474U uses a spraying method to clean the drive shaft. However, the spraying method often leads to problems of incomplete and uneven cleaning. Ultrasonic cleaning, such as an ultrasonic rinsing device for drive shaft processing with patent publication number CN107413742A, mainly relies on the cavitation effect generated by ultrasonic waves in the cleaning liquid to remove dirt. Although the drive shaft is cleaned comprehensively and evenly, its cleaning power is lower than that of the spraying method. In summary, drive shaft cleaning still has certain limitations.

[0003] On the one hand, relying solely on ultrasonic cleaning is not effective for some stubborn dirt attached to the drive shaft surface. During use, the drive shaft will be contaminated with various complex oils, impurities, etc., and some dirt will adhere to its surface tightly, making it difficult for simple ultrasonic cavitation to completely remove it.

[0004] On the other hand, during the cleaning process, multiple ultrasonic cleaning pools are required, such as acid pools, alkaline pools and pure water pools for cleaning in sequence. The material frames need to be transported between multiple cleaning pools by hand or by robotic arms. The cost of robotic arms is high, and manual operation affects efficiency. At the same time, the cleaning agents can also cause harm to the human body. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the existing technology, the present invention provides a cleaning equipment for a drive shaft production line, which has the advantages that the shaking of the lifting legs makes it easier for dirt to fall off, and the lifting legs can automatically transfer the material frame to the next cleaning pool. It solves the problem in the existing technology that the cleaning effect of some stubborn dirt attached to the surface of the drive shaft is poor, and the transportation of the material frame between multiple cleaning pools requires manual or robotic arms.

[0007] (2) Technical solution

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A cleaning device for a drive shaft production line, comprising a plurality of ultrasonic cleaning tanks arranged side by side, each ultrasonic cleaning tank being provided with a support frame, a transition conveyor being provided between two adjacent ultrasonic cleaning tanks, a main lifting frame being provided in any support frame and being lifted and connected to the ultrasonic cleaning tank, two symmetrical secondary lifting legs being also lifted and connected to the bottom of the main lifting frame, the two secondary lifting legs being lifted and lowered in opposite directions, an extension plate being fixedly provided on each of the secondary lifting legs and being perpendicular to the lifting direction, a support tube being provided above the extension plate, the bottom of one side of the support tube being rotatably connected to one of the extension plates, the bottom of the other side being provided with a sliding block being slidably connected, the bottom of the slider being rotatably connected to the other extension plate, and the sliding plane of the top surface of the transition conveyor being provided with an inclined plane;

[0010] After the support tube drags the material frame equipped with the transmission shaft into the ultrasonic cleaning tank, the two secondary lifting legs are controlled to lift and lower in opposite directions, so that the material frame shakes to promote the falling of dirt. After the cleaning is completed and the frame leaves the water surface, shaking can also promote the falling of water stains. At the same time, the inclination angle of the support tube can be changed by controlling the secondary lifting legs, so that the material frame slides by gravity to the next ultrasonic cleaning tank for the next cleaning, thereby realizing automatic cleaning.

[0011] Preferably, the support tube is a hollow tube, and two buoyancy blocks are symmetrically arranged on the front and rear sides of the support tube. When water is injected into the hollow tube of the support tube, the buoyancy blocks float up due to buoyancy and thus protrude upward from the upper surface of the support tube. After the water in the support tube is lost, the buoyancy blocks sink due to gravity and thus hide downward from the upper surface of the support tube. The purpose is to make the buoyancy blocks float up to limit the two sides of the material frame after the support frame drags the material frame into the cleaning liquid, thereby preventing the material frame from sliding on the support tube during the shaking process.

[0012] Preferably, the support tube is provided with an opening at one end in the forward direction of the material frame and a seal at the other end, and the liquid enters and exits the support tube through the opening;

[0013] During the process of the support frame shaking the material frame with water, the sealed end in the support tube is lower than the open end, and the liquid gathers at one end of the buoyancy block, causing the buoyancy block close to the sealed end to bulge upward, thereby limiting the material frame during the shaking process. During the process of the support frame driving the material frame to tilt and allowing the material frame to enter the next ultrasonic cleaning tank, the sealed end is higher than the open end, and the remaining liquid in the support tube is discharged from the opening. At this time, the two buoyancy blocks lose their buoyancy and sink, thereby releasing the limit on the buoyancy blocks, causing the material frame to slide in the forward direction. At the same time, the support frame in the next ultrasonic cleaning tank also presents a tilted state, and the open end of the support tube in the next ultrasonic cleaning tank is immersed in the cleaning liquid, causing the buoyancy block close to the opening to float up, thereby supporting the sliding material frame.

[0014] Preferably, the height of the inclined surface of the top surface of the transition conveyor belt is higher on the side close to the material frame feeding than on the side close to the material frame advancing direction, so that the material frame can slide forward better by gravity.

[0015] Preferably, the buoyancy block is made of hollow plastic material.

[0016] Preferably, four ultrasonic cleaning tanks are included, and each ultrasonic cleaning tank contains an acidic detergent, pure water, an alkaline detergent and pure water respectively, arranged in the forward direction of the material frame.

[0017] Preferably, a feeding conveyor belt is provided in front of the first ultrasonic cleaning tank, a discharging conveyor belt is provided behind the last ultrasonic cleaning tank, and a drying device is provided behind the discharging conveyor belt, that is, at the very end of the conveyor belt.

[0018] Preferably, the drying device includes a lifting platform and a drying blower box. The material frame enters the lifting platform through a discharge conveyor belt and then sinks into the drying blower box. The drying blower box dries the drive shaft in the material frame by blowing out hot air.

[0019] Preferably, the feed conveyor belt, transition conveyor belt and discharge conveyor belt are all roller conveyor belts, and the rollers on the conveyor belts are driven to rotate by motors.

[0020] Preferably, the two secondary lifting legs are respectively connected to the two ends of a cable, a cable winding motor is fixed on the main lifting frame, a cable winding drum is fixed on the output shaft of the cable winding motor, the middle section of the cable is wound around the cable winding drum, and the two secondary lifting legs are controlled to rise and fall in opposite directions by forward and reverse rotation of the cable winding motor, and a corner roller is provided in the main lifting frame at the place where the cable turns.

[0021] (3) Beneficial effects

[0022] Compared with the prior art, the present invention provides a cleaning device for a transmission shaft production line, which has the following beneficial effects:

[0023] 1. The cleaning equipment in the drive shaft production line is equipped with two secondary lifting legs at the bottom of the original lifting support frame. By controlling the two secondary lifting legs to lift and lower in opposite directions, the material frame carried on the support tube is shaken slightly, which promotes the shedding of dirt attached to the drive shaft. At the same time, the structure can also shake the water after the material frame leaves the cleaning liquid to prevent the cleaning liquid from adhering to the drive shaft and entering the next cleaning liquid pool. In particular, when the two cleaning liquid pools have different acidity and alkalinity, the purpose of reducing the loss of cleaning liquid is achieved. In addition, the structure can also change the inclination angle of the support tube to make the material frame automatically slide to the support tube in the next ultrasonic cleaning tank, thereby realizing the function of automatic transportation.

[0024] 2. The cleaning equipment in the drive shaft production line sets the support tube as a hollow tube structure. After the cleaning liquid enters the support tube, the cleaning liquid is injected into the cavity of the support tube. Two buoyancy blocks are also set in the support tube. After water is injected, the buoyancy blocks float up due to buoyancy. The buoyancy blocks protrude from the top of the support tube, thereby limiting the material frame and preventing the material frame from sliding during shaking.

[0025] 3. The cleaning equipment in the drive shaft production line sets a seal and an opening at both ends of the support tube. During the process of the support frame shaking the material frame with water, the sealed end in the support tube is lower than the open end, and the liquid gathers at one end of the buoyancy block, causing the buoyancy block close to the sealed end to bulge upward, thereby limiting the material frame during the shaking process. During the process of the support frame driving the material frame to tilt and causing the material frame to enter the next ultrasonic cleaning tank, the sealed end is higher than the open end, and the remaining liquid in the support tube is discharged from the opening. At this time, the two buoyancy blocks lose their buoyancy and sink, thereby releasing the limit on the buoyancy blocks, causing the material frame to slide in the forward direction. At the same time, the support frame in the next ultrasonic cleaning tank also presents a tilted state, and the open end of the support tube in the next ultrasonic cleaning tank is immersed in the cleaning liquid, causing the buoyancy block close to the opening to float up, thereby supporting the sliding material frame.

In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0041] Example 1:

[0042] This embodiment provides a cleaning device for a drive shaft production line, which has the following technical features.

[0043] See also Figure 1-10 , a cleaning device in a transmission shaft production line, comprising four ultrasonic cleaning pools 1 arranged side by side, each ultrasonic cleaning pool 1 being provided with a support frame 2, a transition conveyor belt 32 being provided between two adjacent ultrasonic cleaning pools 1, and any support frame 2 comprising a main lifting frame 21 connected to the ultrasonic cleaning pool 1 by lifting, two symmetrical secondary lifting legs 22 being connected to the bottom of the main lifting frame 21 by lifting, the lifting directions of the two secondary lifting legs 22 being opposite, an extension plate 23 being fixedly provided perpendicular to the lifting direction on the two secondary lifting legs 22, two support tubes 24 being provided above the extension plate 23, the bottom of one side of the support tube 24 being rotatably connected to one of the extension plates 23, the bottom of the other side being provided with a sliding block connected by sliding, the bottom of the slider being rotatably connected to the other extension plate 23, and the sliding plane of the top surface of the transition conveyor belt 32 being provided with an inclined plane;

[0044] After the support tube 24 drags the material frame 5 equipped with a transmission shaft into the ultrasonic cleaning tank 1, the two secondary lifting legs 22 are controlled to lift and lower in opposite directions, so that the material frame 5 shakes to promote the falling of dirt. After the cleaning is completed and the dirt leaves the water surface, shaking can also promote the falling of water stains. At the same time, the inclination angle of the support tube 24 can be changed by controlling the secondary lifting legs 22, so that the material frame 5 slides by gravity to the next ultrasonic cleaning tank 1 for the next cleaning step, thereby realizing automatic cleaning.

[0045] It is further provided that the support tube 24 is a hollow tube, and two buoyancy blocks 241 are symmetrically arranged on the front and rear sides of the support tube 24. When water is injected into the hollow tube of the support tube 24, the buoyancy blocks 241 float up due to buoyancy and thus protrude upward from the upper surface of the support tube 24. After the water in the support tube 24 is lost, the buoyancy blocks 241 sink due to gravity and thus hide downward from the upper surface of the support tube 24. The purpose is to make the support frame 2 drag the material frame 5 into the cleaning liquid, and the buoyancy blocks 241 float up to limit the two sides of the material frame 5, thereby preventing the material frame 5 from sliding on the support tube 24 during the process of shaking the material frame 5.

[0046] Furthermore, an opening 243 is provided at one end of the support tube 24 in the forward direction of the material frame 5 and a sealing opening 242 is provided at the other end, and the liquid enters and exits the support tube 24 through the opening 243;

[0047] During the process of the support frame 2 shaking the material frame 5 with water, one end of the seal 242 in the support tube 24 is lower than one end of the opening 243, and the liquid gathers at one end of the buoyancy block 241, causing the buoyancy block 241 near the end of the seal 242 to bulge upward, limiting the material frame 5 during the shaking process. During the process of the support frame 2 driving the material frame 5 to tilt so that the material frame 5 enters the next ultrasonic cleaning tank 1, one end of the seal 242 is higher than one end of the opening 243, and the remaining liquid in the support tube 24 is discharged from the opening 243. At this time, the two buoyancy blocks 241 lose their buoyancy and sink, thereby releasing the limit on the buoyancy blocks 241, allowing the material frame 5 to slide in the forward direction. At the same time, the support frame 2 in the next ultrasonic cleaning tank 1 also presents a tilted state, and one end of the opening 243 of the support tube 24 in the next ultrasonic cleaning tank 1 is immersed in the cleaning liquid, causing the buoyancy block 241 near the opening 243 to float up, thereby supporting the sliding material frame 5.

[0048] Furthermore, the slope of the top surface of the transition conveyor belt 32 is higher on the side close to the feeding direction of the material frame 5 than on the side close to the advancing direction of the material frame 5, so that the material frame 5 can slide forward better by gravity.

[0049] It is further provided that the buoyancy block 241 is made of hollow plastic material.

[0050] Furthermore, four ultrasonic cleaning tanks 1 are provided, and each ultrasonic cleaning tank 1 contains an acidic detergent, pure water, an alkaline detergent and pure water respectively, arranged in the forward direction of the material frame 5 .

[0051] Furthermore, a feeding conveyor belt 31 is provided in front of the first ultrasonic cleaning tank 1, and a discharging conveyor belt 33 is provided behind the last ultrasonic cleaning tank 1. A drying device 4 is provided behind the discharging conveyor belt 33, that is, at the very end of the conveyor belt.

[0052] It is further provided that the drying device 4 includes a lifting platform and a drying blower. The material frame 5 enters the lifting platform through the discharge conveyor belt 33 and then sinks into the drying blower. The drying blower dries the drive shaft in the material frame 5 by blowing out hot air.

[0053] It is further provided that the feed conveyor belt 31, the transition conveyor belt 32 and the discharge conveyor belt 33 are all roller conveyor belts, and the rollers on the conveyor belts are driven to rotate by motors.

[0054] It is further provided that the two ends of a cable 25 are respectively connected to the two secondary lifting legs 22, a cable winding motor 27 is fixed on the main lifting frame 21, a cable winding drum 26 is fixed on the output shaft of the cable winding motor 27, the middle section of the cable 25 is wound around the cable winding drum 26, and the two secondary lifting legs 22 are controlled to rise and fall in opposite directions by the forward and reverse rotation of the cable winding motor 27, and a corner roller 211 is provided in the main lifting frame 21 at the corner where the cable 25 turns.

[0055] It is further provided that an ultrasonic generator is provided on the inner wall of the ultrasonic cleaning tank 1 .

[0056] Furthermore, a liquid inlet and outlet are provided in the ultrasonic cleaning tank 1 for replacing the cleaning liquid.

[0057] Furthermore, a heating device is provided in the ultrasonic cleaning tank 1 for increasing the temperature of the cleaning liquid.

[0058] It is further provided that each support frame 2 is fixed on a different lifting plate, and each lifting plate passes through a guide rail and a screw rod, one end of the screw rod is connected to the output shaft of the motor, and the motor drives the screw rod to rotate to control the lifting of the lifting plate.

[0059] Furthermore, a slope 244 is provided on the inner wall of the bottom of the support tube 24 near the opening 243 to prevent the liquid in the support tube 24 from escaping from the support tube 24 due to shaking during the shaking process.

[0060] Furthermore, at least two support tubes 24 are provided between the two extension plates 23 .

[0061] It is further provided that the lower rotating seat 231 is fixed to the extension plate 23 by bolts, and each lower rotating seat 231 is rotatably connected to the upper rotating seat 232. The top of one of the upper rotating seats 232 on the two extension plates 23 is fixed to the bottom of one side of the support tube 24 by bolts, and the top of the other upper rotating seat 232 is slidably connected to the bottom of the other side of the support tube 24.

[0062] To sum up, the cleaning equipment in the drive shaft production line is further provided with two secondary lifting legs 22 at the bottom of the support frame 2 that is originally lifted and connected. By controlling the two secondary lifting legs 22 to lift and lower in opposite directions, the material frame 5 carried on the support tube 24 is caused to shake slightly, which promotes the shedding of dirt attached to the drive shaft. At the same time, the structure can also shake the water after the material frame 5 leaves the cleaning liquid to prevent the cleaning liquid from adhering to the drive shaft and entering the next cleaning liquid pool, especially when the two cleaning liquid pools have different acidity and alkalinity, thereby achieving the purpose of reducing the loss of cleaning liquid. In addition, the structure can also change the inclination angle of the support tube 24 to make the material frame 5 automatically slide to the support tube 24 in the next ultrasonic cleaning pool 1, thereby realizing the function of automatic transportation.

[0063] The cleaning equipment in the drive shaft production line is configured such that the support tube 24 is formed into a hollow tube structure. After the cleaning liquid enters the support tube 24, the cleaning liquid is injected into the cavity of the support tube 24. Two buoyancy blocks 241 are also provided in the support tube 24. After water is injected, the buoyancy blocks 241 float upward due to buoyancy. The buoyancy blocks 241 protrude from above the support tube 24, thereby limiting the material frame 5 and preventing the material frame 5 from sliding during shaking.

[0064] The cleaning equipment in the transmission shaft production line is provided with a seal 242 and an opening 243 at both ends of the support tube 24. When the support frame 2 shakes the material frame 5 with water, one end of the seal 242 in the support tube 24 is lower than one end of the opening 243. The liquid gathers at one end of the buoyancy block 241, so that the buoyancy block 241 near the end of the seal 242 bulges upward, limiting the material frame 5 during the shaking process. When the support frame 2 drives the material frame 5 to tilt so that the material frame 5 enters the next ultrasonic cleaning tank 1, the seal One end of 242 is higher than one end of the opening 243, and the remaining liquid in the support tube 24 is discharged from the opening 243. At this time, the two buoyancy blocks 241 lose their buoyancy and sink, thereby releasing the limit on the buoyancy blocks 241, so that the material frame 5 slides in the forward direction. At the same time, the support frame 2 in the next ultrasonic cleaning tank 1 is also tilted, and one end of the opening 243 of the support tube 24 in the next ultrasonic cleaning tank 1 is immersed in the cleaning liquid, so that the buoyancy block 241 close to the opening 243 floats up, thereby supporting the sliding material frame 5.
