[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] See also Figure 1-Figure 6 As shown, a self-cleaning conveying equipment for logistics sorting includes a main conveying frame 11 and a branch conveying frame 12 installed on the main conveying frame 11 for logistics sorting, the conveying equipment also includes a plurality of conveying rollers 13 equidistantly rotatably installed in the main conveying frame 11, a driving motor 14 is fixedly installed on the main conveying frame 11, and the output end of the driving motor 14 is interconnected with the conveying roller 13, a driving gear 15 is coaxially connected to the conveying roller 13, a driven gear 15 is meshedly connected between two adjacent driving gears 15, and the driven gear 16 is rotatably installed on the main conveying frame 11; a cylinder 21 is fixedly installed in the main conveying frame 11, a lifting frame 22 is fixedly installed at the output end of the cylinder 21, a cleaning assembly 23 is fixedly installed on the lifting frame 22, a plurality of groups of cleaning assemblies 23 are equidistantly arranged in the main conveying frame 11, and the cleaning assembly 23 is arranged between two adjacent conveying rollers 13.

[0036] The main conveyor frame 11 is used in conjunction with a sorting robot. Logistics items are placed on the conveyor rollers 13 on the main conveyor frame 11. The conveyed items are classified by the robot, and the items are clamped and placed on the branch conveyor frame 12 for outward output to achieve logistics sorting. The driving motor 14 is operated to control the rotation of the conveyor rollers 13 on the side of the main conveyor frame 11. The conveyor rollers 13 distributed in horizontal rows with equal intervals are all provided with driving gears 15. Adjacent driving gears 15 are meshed and connected with driven gears 16. Under the transmission action of the driving gears 15 and the driven gears 16, multiple conveyor rollers 13 in the horizontal row can be kept rotating in the same direction to achieve the transportation of items.

[0037] Some items in logistics transportation have stains on their surfaces. When conveying items, the conveyor roller 13 rolls and contacts the surface of the items, and the stains on the items are transferred to the conveyor roller 13. The surface of the conveyor roller 13 in working state can be cleaned by the cleaning component 23.

[0038] See also Figure 3-Figure 8 As shown, the cleaning assembly 23 includes a support frame 231 fixed on the lifting frame 22, a guide support 232 is fixed on the support frame 231, a transverse water pipe 233 is slidably connected in the guide support 232, a plurality of vertical frames 234 are equidistantly fixed on the transverse water pipe 233, two cleaning cylinders 235 are symmetrically mounted on the vertical frames 234 about the transverse water pipe 233, and the cleaning cylinders 235 are in contact with the outer wall of the conveying roller 13; a transmission assembly 3 for controlling the reciprocating movement of the transverse water pipe 233 is provided on the support frame 231.

[0039] When the conveying roller 13 rotates, power is transmitted to the transverse water pipe 233 through the transmission assembly 3, and the transverse water pipe 233 is controlled to move back and forth in the guide support 232. The transverse water pipe 233 drives the vertical frame 234 and the cleaning cylinder 235 to move synchronously, so that the cleaning cylinder 235 is in contact with the outer wall of the conveying roller 13 and moves back and forth, thereby realizing the cleaning operation of the outer wall of the conveying roller 13.

[0040] See also Figure 4-Figure 7 As shown, the transmission assembly 3 includes a mounting base 31 fixedly mounted on the main conveying frame 11, a transmission gear 32 is rotatably mounted on the mounting base 31, the transmission gear 32 is meshingly connected with the driven gear 16, a power bevel gear 33 is coaxially connected to the transmission gear 32, a driven bevel gear 34 is meshingly connected to the power bevel gear 33, and the driven bevel gear 34 is rotatably mounted on the mounting base 31; a driving arm 36 is rotatably mounted on the support frame 231, a connecting mechanism 35 is connected between the driving arm 36 and the driven bevel gear 34, a push rod 37 is rotatably connected to the driving arm 36, and the push rod 37 is rotatably connected to the horizontal water pipe 233.

[0041] When the conveying roller 13 rotates, it drives the driving gear 15 and the driven gear 16 to rotate. The driven gear 16 drives the transmission gear 32 to rotate through meshing transmission. The transmission gear 32 drives the coaxially fixed power bevel gear 33 to rotate synchronously. The power bevel gear 33 is meshed and connected with the driven bevel gear 34 to drive them to rotate synchronously. The driven bevel gear 34 drives the connecting mechanism 35 and the driving arm 36 to rotate, so that the two ends of the push rod 37 connected between the driving arm 36 and the horizontal water pipe 233 rotate, and the rotating push rod 37 pushes the horizontal water pipe 233 to reciprocate in the guide support 232, thereby achieving the purpose of driving the horizontal water pipe 233.

[0042] See also Figure 6 and Figure 7 As shown, the connection mechanism 35 includes a toothed shaft rod 351 coaxially connected to the driven bevel gear 34 and an internal gear rotating rod 352 coaxially connected to the driving arm rod 36 , and the toothed shaft rod 351 is engaged with the internal gear rotating rod 352 .

[0043] When the conveying roller 13 is not cleaned, the operating cylinder 21 controls the lifting frame 22 to move downward, and the lifting frame 22 drives the supporting frame 231 to move downward synchronously, and the inner gear rotating rod 352 on the supporting frame 231 moves downward and separates from the toothed shaft rod 351. At this time, the cleaning cylinder 235 moves away from the conveying roller 13 to reduce the resistance to the rotation of the conveying roller 13. When cleaning the conveying roller 13, the operating cylinder 21 pushes the lifting frame 22 to move upward, and the lifting frame 22 controls the supporting frame 231 and the inner gear rotating rod 352 to move upward synchronously, so that the inner gear rotating rod 352 is sleeved on the outside of the toothed shaft rod 351, so that when the driven bevel gear 34 rotates, the toothed shaft rod 351 and the inner gear rotating rod 352 can control the rotation of the driving arm rod 36.

[0044] See also Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, a hose 41 is connected through the transverse water pipe 233, one end of which is mounted on the main conveying frame 11, and a plurality of longitudinal water pipes 42 are connected through the transverse water pipe 233 at equal intervals, the longitudinal water pipe 42 is fixed in the vertical frame 234, and an atomizing nozzle 43 is rotatably mounted on the longitudinal water pipe 42.

[0045] The hose 41 is connected to the pipe that provides the water source. The cleaning liquid is controlled to enter the atomizing nozzle 43 through the hose 41, the horizontal water pipe 233, and the longitudinal water pipe 42. The cleaning liquid is atomized and sprayed on the surface of the conveying roller 13 through the atomizing nozzle 43. The movable cleaning cylinder 235 combined with the cleaning liquid can better clean the stains on the surface of the conveying roller 13.

[0046] See also Figure 8 and Fig. 9As shown, an inner rack 45 is fixedly installed in the main conveying frame 11 , and a gear ring 44 is meshedly connected to the inner rack 45 , and the gear ring 44 is coaxially sleeved on the outside of the atomizing nozzle 43 .

[0047] When the stand 234 drives the cleaning cylinder 235 to move back and forth, the atomizing nozzle 43 installed on the stand 234 moves back and forth synchronously, the gear ring 44 on the atomizing nozzle 43 engages with the inner rack 45 to rotate, and the gear ring 44 drives the atomizing nozzle 43 to rotate synchronously, adjusting the angle of the atomizing nozzle 43 spraying the cleaning liquid, so that the cleaning liquid can be effectively sprayed on the outside of the conveying roller 13.

[0048] See also Figure 1 , Figure 2 and Fig.10 As shown, a monitoring component 5 for movably monitoring stains on the surface of the conveying roller 13 is provided on the main conveying frame 11 .

[0049] The monitoring component 5 is moved to monitor the multiple conveying rollers 13 on the main conveying frame 11 in real time, and stains on the conveying rollers 13 are quickly identified so that the stains can be cleaned in time.

[0050] See also Figure 10-13 As shown, the monitoring assembly 5 includes a slide frame 51 fixedly mounted on the main conveyor frame 11, a screw rod 52 is rotatably connected to the slide frame 51, a mobile frame 53 is slidably mounted on the slide frame 51, and the mobile frame 53 is threadedly connected to the screw rod 52, and a camera 54 is fixedly mounted on the mobile frame 53.

[0051] A servo motor is installed on the slide frame 51, and the output end of the servo motor is connected to the screw rod 52. The screw rod 52 rotates to control the moving frame 53 to move back and forth on the slide frame 51 through threaded transmission. When the moving frame 53 moves, the monitoring range of the camera 54 is adjusted to effectively identify the conveying roller 13 with stains on the surface.

[0052] See also Figure 11-Figure 15 As shown, a drying assembly 55 for drying water stains on the surface of the conveying roller 13 is provided on the mobile frame 53; the drying assembly 55 comprises a fixed frame 551 fixed on the mobile frame 53, a steering frame 552 is rotatably mounted on the fixed frame 551, a wind shield 553 is fixedly mounted on the steering frame 552, and a fan blade 554 is rotatably mounted in the fan shield 553; a power assembly 56 for driving the fan blade 554 to rotate is provided on the fixed frame 551. When the movable frame 53 moves, it drives the wind cover 553 and the fan blades 554 to move synchronously. The fan blades 554 are controlled to rotate by the power assembly 56. The wind force generated by the fan blades 554 acts on the surface of the conveying roller 13 to achieve air drying of water stains on the surface of the conveying roller 13.

[0053] See also Figure 11-Figure 15As shown, the power assembly 56 includes an external rack 561 fixed on the sliding frame 51, and the external rack 561 is meshed with a flat gear 562, which is rotatably mounted on the moving frame 53, and a first-stage bevel gear 563 is coaxially connected to the flat gear 562, and a second-stage bevel gear 564 is meshed with the first-stage bevel gear 563, which is rotatably mounted on the fixed frame 551, and a third-stage bevel gear 565 is meshed with the second-stage bevel gear 564, which is rotatably mounted on the bogie 552, and the third-stage bevel gear 565 is coaxially connected to the fan blade 554; a hydraulic rod 566 is rotatably connected to the moving frame 53, and the output end of the hydraulic rod 566 is rotatably connected to the wind cover 553.

[0054] The hydraulic rod 566 is operated, and the hydraulic rod 566 is connected between the movable frame 53 and the wind hood 553 to drive the wind hood 553 to rotate. The bogie 552 on the wind hood 553 is connected to the fixed frame 551 to rotate, so as to adjust the angle of the wind output by the fan blade 554 and expand the range of drying the surface of the conveying roller 13.

[0055] The movable frame 53 moves laterally and drives the flat gear 562 to move synchronously. The flat gear 562 meshes with the outer rack 561 to rotate. The flat gear 562 drives the primary bevel gear 563 to rotate synchronously. The secondary bevel gear 564 next to the primary bevel gear 563 rotates under the meshing transmission. The secondary bevel gear 564 is meshed and connected with the tertiary bevel gear 565, and drives the tertiary bevel gear 565 to rotate under the meshing transmission. The tertiary bevel gear 565 is coaxially connected with the fan blade 554 to achieve the purpose of driving the fan blade 554 to rotate, and the secondary bevel gear 564 is colinear with the rotation axis of the bogie 552. When the bogie 552 rotates, the tertiary bevel gear 565 on the bogie 552 rotates along the outer circumference of the secondary bevel gear 564, so that after adjusting the angle of the bogie 552 and the fan blade 554, the power assembly 56 can still control the rotation of the fan blade 554.

[0056] Working principle: Items are moved and sorted on the conveying roller 13 on the main conveying frame 11. When stains appear on the surface of the conveying roller 13, the operating cylinder 21 pushes the lifting frame 22 and the support frame 231 to move up, so that the inner tooth rotating rod 352 on the support frame 231 is sleeved on the outside of the toothed shaft rod 351, and the cleaning cylinder 235 is attached to the outside of the conveying roller 13. The rotation of the conveying roller 13 drives the driving gear 15 and the driven gear 16 to rotate synchronously. The driven gear 16 is meshed with the transmission gear 32 to control the rotation of the transmission gear 32. The moving gear 32 drives the power bevel gear 33 to rotate synchronously. Under the meshing transmission, the power bevel gear 33 drives the driven bevel gear 34 to rotate. The driven bevel gear 34 drives the driving arm 36 below to rotate through the connecting mechanism 35. The two ends of the push rod 37 connected between the driving arm 36 and the horizontal water pipe 233 rotate accordingly. The rotating push rod 37 pushes the horizontal water pipe 233 to reciprocate along the direction of the guide support 232, thereby achieving the purpose of driving the horizontal water pipe 233, the stand 234 and the cleaning cylinder 235 to reciprocate.

[0057] The cleaning cylinder 235 is attached to the surface of the conveying roller 13 when it moves back and forth, and cleans the stains on its surface. At the same time, the cleaning liquid is transported to the atomizing nozzle 43 through the hose 41, the horizontal water pipe 233 and the longitudinal water pipe 42. The atomizing nozzle 43 atomizes the cleaning liquid and sprays it onto the surface of the conveying roller 13, so that the cleaning cylinder 235 can better clean the stains on the surface of the conveying roller 13. At the same time, the atomizing nozzle 43 rotates due to the meshing transmission action of the ring gear 44 and the inner rack 45 while following the reciprocating movement of the stand 234. The rotating atomizing nozzle 43 can better spray the cleaning liquid onto the surface of the conveying roller 13.

[0058] When the screw rod 52 rotates, the moving frame 53 is controlled to slide on the sliding frame 51. The camera 54 on the moving frame 53 can monitor the stains on the surface of the conveying roller 13 in real time, so as to clean the conveying roller 13 in time. When the moving frame 53 moves, the flat gear 562 meshes with the outer rack 561 and rotates. The flat gear 562 drives the first-stage bevel gear 563 to rotate synchronously. Through the meshing transmission of the first-stage bevel gear 563, the second-stage bevel gear 564 and the third-stage bevel gear 565, the fan blade 554 is controlled to rotate. The fan blade 554 outputs wind force to the surface of the conveying roller 13, thereby accelerating the drying of water stains on the surface of the conveying roller 13 after cleaning.

[0059] The operating hydraulic rod 566 controls the rotation of the wind hood 553 and the bogie 552, and adjusts the direction of the wind output by the fan blade 554, so that the wind can better act on the surface of the conveying roller 13. The rotation of the fan blade 554 can expand the range of its blowing and drying, so that the surface of the conveying roller 13 can dry quickly.

[0060] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
