[0035] Embodiment 1

[0036] As Figures 1 to 11As shown, the automatic polishing device for automobile luggage rack based on the rotary chain type includes a rotary chain a1, a rotary chain b2, a feeding assembly 3, a fixing assembly 4, and a polishing machine 5, characterized in that a plurality of fixing blocks 6 are arranged on the rotary chain a1 and the rotary chain b2, a sliding rod 7 is slidably arranged on the fixing block 6, a sliding rail 8 is arranged on the side of the rotary chain, a cleaning head 9 is arranged at the end of the sliding rod 7, and a rack a10 and a rack b11 are respectively arranged on the side of the rotary chain a1 and the rotary chain b2 for driving the sliding rod 7 to rotate, and the cleaning head 9 is extended into the row under the drive of the sliding rail 8 during the process of the sliding rod 7 moving with the rotary chain. The luggage rack is in the luggage rack, and under the action of the rack a10 and the rack b11, the cleaning heads 9 on both sides rotate in an staggered manner to clean the ends of the luggage rack. The fixed component 4 includes a top block 12 and an extrusion block 13 slidably arranged in the slide rod 7. The side of the slide rail 8 is provided with a rack c14 for driving the slide rod 7 to flip. After the cleaning head 9 cleans the luggage rack, the slide rod 7 continues to move under the action of the slide rail 8, thereby driving the extrusion block 13 to move. The extrusion block 13 drives the top block 12 to extend out from the inside to press against the luggage rack, thereby cooperating with the polishing machine 5 to polish the luggage rack, and drives the slide rod 7 to flip under the action of the rack c14, thereby polishing the other side of the luggage rack.

[0037] like Figure 4 , Figure 5 As shown, the feeding assembly 3 includes a support frame 21 and a conveyor belt 22 arranged above the support frame 21, a plurality of feeding troughs 23 are arranged on the conveyor belt 22, a paddle 24 is arranged on the feeding trough 23, a feeding frame 25 and a feeding channel 26 obliquely arranged on the feeding frame 25 are arranged above the conveyor belt 22, and drop rods 27 are arranged on both sides of the lower end of the feeding frame 25, and the drop rods 27 are arranged to be an arc shape with the same diameter as the luggage rack.

[0038] In addition, materials are manually replenished from the loading channel 26, and the luggage racks roll down into the loading frame 25 through the loading channel 26 and are accumulated in the loading frame 25, and the luggage racks at the bottom fall on the drop rod. When the conveyor belt 22 moves, the luggage racks are pushed away from the drop rod 27 through the shifting rod 24 and fall into the loading trough 23, and at the same time, the luggage racks above move downward to replenish materials, so that the shifting rod 24 takes away a luggage rack when passing by, thereby realizing sequential loading.

[0039] like Figure 2 , Figure 6 , Figure 11 As shown, the size of the cleaning head 9 is set to be the same as the inner diameter of the luggage rack, the diameter of the slide bar 7 is larger than the diameter of the luggage rack, the end of the cleaning head 9 is conical and the surface is rough, a plurality of gear teeth 31 are set on the surface of the slide bar 7, the rack a10 is set below the gear teeth 31, and the rack b11 is set below the gear teeth 31.

[0040] It is worth mentioning that after the cleaning head 9 extends into the interior of the luggage rack, under the action of the rack a10 and the rack b11, the cleaning heads 9 on both sides rotate clockwise and counterclockwise respectively, so as to clean the port of the luggage rack through the rough surface of the cleaning head 9.

[0041] As Figure 7 , Figure 8 shown, a groove 41 is provided on one side of the sliding rod 7 where the cleaning head 9 is located. A hydraulic channel 42 is provided inside the groove 41 and the sliding rod 7. The top block 12 and the extrusion block 13 are respectively arranged on the side surface of the sliding rod 7 and the surface of the groove 41. Hydraulic oil is placed in the hydraulic channel 42. A spring is provided between the extrusion block 13 and the wall surface of the hydraulic channel 42.

[0042] It should be noted here that during the process of the sliding rod 7 continuing to move under the action of the slide rail 8, the end of the luggage rack drives the extrusion block 13 to move, so as to drive the top block 12 to extend through the hydraulic channel 42. While the end face of the groove 41 abuts against the end face of the luggage rack, the top block 12 supports the luggage rack from the inside, preventing the luggage rack from shifting during the subsequent polishing process.

[0043] As Figure 2 , Figure 6 shown, a holding block 51 is provided on the sliding rod 7. A holding strip 52 is provided below the polishing machine 5. The distance between the holding strips 52 is equal to the thickness of the holding block 51. The rack c14 is provided between two groups of polishing machines 5. The holding strip 52 is disconnected at the rack c14.

[0044] It should be mentioned here that when the sliding rod 7 drives the luggage rack to move under the polishing machine 5, at this time, the holding block 51 slides into the holding strip 52, and the holding strip 52 limits the up and down movement of the holding block 51, thereby preventing the sliding rod 7 from deflecting during the polishing of the luggage rack.

[0045] As Figure 5 shown, the interval of the feeding trough 23 is the same as the diameter of the luggage rack. A limiting plate 61 is provided at the end of the feeding trough 23 and is inclined outward.

[0046] It is worth mentioning here that through the limiting plate 61, the feeding trough 23 can more stably receive the luggage rack, preventing the luggage rack from shifting and falling outside the feeding trough 23.

[0047] As Figure 9 shown, a number of convex portions are provided on the slide rail 8. The number of convex portions is divided into a cleaning section 71, a fixing section 72, and a blanking section 73.

[0048] It should be noted that when the fixed block 6 passes through the cleaning section 71, the convex part of the cleaning section 71 drives the sliding rod 7 to move towards the luggage rack, so that the cleaning head 9 extends into the luggage rack. When the fixed block 6 passes through the fixed section 72, the cleaning head 9 completes the cleaning and continues to move towards the luggage rack under the action of the fixed section 72, so as to drive the extrusion block to move through the luggage rack, and then drive the top block to rise to support the luggage rack from the inside. When the fixed block passes through the blanking section 73, the sliding rod disengages from the slide rail, the extrusion block resets under the action of the spring to disengage the top block from the inner wall surface of the luggage rack, and the sliding rod resets under the action of the spring to drive the cleaning head 9 to disengage from the luggage rack.

[0049] As Figure 6 shown, the contact surface between the sliding rod 7 and the slide rail 8 is set to be hemispherical.

[0050] It should be noted here that by setting the contact surface between the sliding rod 7 and the slide rail 8 to be hemispherical, the friction between the sliding rod 7 and the surface of the slide rail 8 during rotation can be greatly reduced, and the service life can be greatly improved.

[0051] As Figure 6 shown, a limit ring 91 is provided on the sliding rod 7, and a spring sleeved on the sliding rod 7 is provided between the limit ring 91 and the gear fixed block 6.

[0052] The number of teeth of the rack c14 is set to be half of the number of teeth of the gear 31.

[0053] It is worth mentioning here that by setting the number of teeth of the rack c14 to be half of the number of teeth of the gear 31, the gear 31 can be driven to rotate 180° by the rack c14, so as to drive the luggage rack to turn over through the sliding rod 7.

[0054] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "front and back", "left and right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0055] Of course, in this technical solution, those skilled in the art should understand that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of one component can be one, while in other embodiments, the number of this component can be multiple. The term "one" should not be construed as a limitation on the number.

[0056] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art in the technical field of the present invention under the technical disclosure of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
