Detailed Implementation

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figures 1 to 9 As shown, a piston rod encircling fully automatic cleaning device includes a housing 1 and a rotary chain 2 disposed within the housing 1. A spray plate 3 is disposed on the top of the housing 1. A bearing assembly 5 for supporting the piston rod 4 and a moving assembly 6 driven by the bearing assembly 5 are disposed on the rotary chain 2. The bearing assembly 5 includes a first rotating roller 51 and a second rotating roller 52. A driving assembly 7 for driving the first rotating roller 51 and the second rotating roller 52 to rotate is disposed within the housing 1. A spray assembly 8 and cleaning assemblies 9 disposed on both sides of the spray assembly 8 are disposed on the moving assembly 6. The bearing assembly 5 drives the piston rod 4 to rotate via the first rotating roller 51 and the second rotating roller 52. The moving assembly 6 is used to drive the spray assembly 8 and the cleaning assembly 9 to reciprocate and clean the piston rod 4.

[0033] In this embodiment, as Figures 3 to 5 As shown, the bearing assembly 5 also includes a fixed base 53 and limiting rings 54 respectively disposed at both ends of the first rotating roller 51 and the second rotating roller 52; in this invention, the piston rod is placed between the first rotating roller 51 and the second rotating roller 52 by a robot or manually, and the two ends of the piston rod are limited by the limiting rings 54.

[0034] It needs to be emphasized that, such as Figure 3 and Figure 6As shown, the moving assembly 6 includes a lever 61, rotating seats 62 disposed at both ends of the lever 61, a limiting frame 63 disposed on the lever 61, a first gear 64 disposed at one end of the lever 61, and a first tooth segment 65 and a second tooth segment 66 disposed on the upper and lower sides of one end of the lever 61; the first tooth segment 65 is provided with a plurality of raised tooth segments a651, and the second tooth segment 66 is provided with a plurality of raised tooth segments b661, the raised tooth segments a651 and the raised tooth segments b661 being alternately arranged; the end of the fixed seat 53 The part is provided with a slider 531, and the inner wall of the housing 1 is provided with a sliding groove 11. The slider 531 is slidably disposed in the sliding groove 11. A connecting rod 67 is provided between the limiting frame 63 and the fixed seat 53. In this invention, the rotation of the rotary chain 2 drives the fixed seat 53 to rotate. Through the connection of the connecting rod 67, the limiting frame 63 is driven to rotate along the path of the rotary chain 2. When the first gear 64 meshes with the interlaced protruding tooth segments a651 and b661 respectively, it drives the lever 61 to rotate alternately clockwise and counterclockwise.

[0035] In addition, such as Figures 5 to 6 As shown, the drive assembly 7 includes a second gear 71 disposed at one end of the first rotating roller 51, a third gear 72 disposed at the other end of the second rotating roller 52, a first rack 73 disposed at the upper end of the second gear 71 and meshing with the second gear 71, and a second rack 74 disposed at the lower end of the third gear 72 and meshing with the third gear 72. In this invention, the second gear 71 meshes with the first rack 73 disposed at the upper end of the second gear 71, and the third gear 72 meshes with the second rack 74 disposed at the lower end of the third gear 72, thereby driving the first rotating roller 51 and the second rotating roller 52 to rotate clockwise and counterclockwise, respectively, thereby driving the piston rod to rotate.

[0036] Furthermore, such as Figure 8 As shown, the spray assembly 8 includes an arc plate 81, a spray hole 82 disposed within the arc plate 81, and a first limiting block 83 disposed at the upper end of the arc plate 81. In this invention, a high concentration of cleaning agent is placed inside the arc plate 81 and sprayed out through the spray hole 82 onto the rotating piston rod.

[0037] It needs to be emphasized that, such as Figure 7 and Figure 8As shown, the cleaning assembly 9 includes a movable plate 91, a first brush 92 and a second brush 93 disposed on the upper end face and side face of the movable plate 91, a first conical tooth 94 disposed on the first brush 92, a second conical tooth 95 disposed on the second brush 93, a fourth gear 96 disposed at the end of the first brush 92, a second limiting block 97 disposed on the movable plate 91, and a third rack 98 disposed on the side face of the limiting frame 63 and meshing with the fourth gear 96. In this invention, when the piston rod 61 rotates, it drives the second limiting block 97 to move. During the movement, the fourth gear 96 meshes with the third rack 98. The rotation of the fourth gear 96 drives the first brush 92 to rotate, and the first conical tooth 94 meshes with the second conical tooth 95, thereby driving the second brush 93 to rotate, thus cleaning the outer surface of the piston rod.

[0038] Work process

[0039] A robotic arm or a person places the piston rod between the first rotating roller 51 and the second rotating roller 52, and limits both ends of the piston rod by the limiting ring 54; the second gear 71 meshes with the first rack 73 located at the upper end of the second gear 71, and the third gear 72 meshes with the second rack 74 located at the lower end of the third gear 72, thereby driving the first rotating roller 51 and the second rotating roller 52 to rotate clockwise and counterclockwise respectively, thereby driving the piston rod to rotate;

[0040] The rotation of the rotary chain 2 drives the fixed seat 53 to rotate. Through the connection of the connecting rod 67, the limiting frame 63 rotates along the path of the rotary chain 2. When the first gear 64 meshes with the interlaced protruding tooth segments a651 and b661 respectively, it drives the lever 61 to rotate alternately clockwise and counterclockwise.

[0041] A high concentration of cleaning agent is placed inside the arc-shaped plate 81 and sprayed out through the nozzle 82 onto the rotating piston rod. When the piston rod 61 rotates, it drives the second limit block 97 to move. During the movement, the fourth gear 96 meshes with the third rack 98. The rotation of the fourth gear 96 drives the first brush 92 to rotate. The first conical tooth 94 meshes with the second conical tooth 95, which in turn drives the second brush 93 to rotate, cleaning the outer surface of the piston rod.

[0042] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art under the technical guidance of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
