Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0026] This utility model discloses a device for detecting damage to a recyclable desiccant pack, comprising a housing 1, a lifting plate 6, a lifting assembly, a rotating plate 15, a rotating assembly, a placement plate 16, a blowing assembly, and a detection assembly; the specific structure is as follows: Figures 1-5 As shown, the housing 1 is a horizontally arranged hollow cuboid structure, and a circular rotating plate 15 is horizontally arranged in the middle of its inner bottom surface. The rotating plate 15 is horizontally rotatably connected to the inner bottom surface of the housing 1 through a rotating assembly. Three placement plates 16 are evenly spaced horizontally along the circumference of the upper surface of the rotating plate 15, and several placement slots 17 matching the desiccant packs are evenly spaced vertically embedded on the upper surface of each placement plate 16. A matching lifting plate 6 is horizontally arranged in the upper middle position inside the housing 1, and the lifting plate 6 moves vertically up and down in the area above the placement plate 16 through a lifting assembly.

[0027] Hydraulic cylinders 2 are vertically and symmetrically installed at four right angles on the inner bottom surface of the housing 1. The four hydraulic cylinders 2 operate synchronously and do not interfere with the vertical up-and-down movement of the lifting plate 6 or the horizontal rotation movement of the rotating plate 15. Figure 1 , Figure 4 As shown, the piston rod of each hydraulic cylinder 2 extends vertically downwards from the lower surface of the housing 1 and is connected to the corresponding caster wheel 3. Support legs 4 are also vertically symmetrically arranged at the four right angles of the lower surface of the housing 1, and each support leg 4 is positioned within a square area enclosed by the four caster wheels 3. When in the upper limit position, the lower end face of each caster wheel 3 is positioned above the horizontal plane where the lower end of the corresponding support leg 4 is located. Driven by the hydraulic cylinder 2, this invention switches between a movement state and a detection state through the cooperation of the caster wheels 3 and the support legs 4.

[0028] like Figure 1As shown, each placement plate 16 is arranged radially along the rotating plate 15, and the included angle between adjacent placement plates 16 is 120°; each placement slot 17 is circular, and its opening size is larger than the specifications of the desiccant pack, and its opening depth is smaller than the thickness of the desiccant pack, thereby ensuring that when the desiccant pack is placed in the corresponding placement slot 17, the upper half of the desiccant pack extends beyond the horizontal plane of the upper surface of the corresponding placement plate 16.

[0029] The lifting assembly of this utility model includes an electric push rod 5, a slide rail 7, a slider, and a limiting plate 8; as shown... Figure 1 , Figure 4 As shown, electric push rods 5 are vertically symmetrically arranged at left and right intervals on the upper surface of the housing 1. The pushing end of the electric push rod 5 extends vertically downward into the interior of the housing 1 and is screwed and fixed to the corresponding position on the upper surface of the lifting plate 6, thereby driving the lifting plate 6 to move vertically up and down inside the housing 1. Slide rails 7 are vertically symmetrically arranged at front and back intervals on the left and right inner sides of the housing 1 relative to the position of the lifting plate 6. Sliders matching slide rails 7 are also provided on the left and right sides of the lifting plate 6 relative to the position of each slide rail 7. The stability of the vertical up and down movement of the lifting plate 6 is ensured by the cooperation of the sliders and slide rails 7. Limiting plates 8 are horizontally arranged at the upper and lower ends of each slide rail 7. Each limiting plate 8 is fixedly connected to the corresponding left and right inner sides of the housing 1 and limits the vertical movement of the lifting plate 6.

[0030] The rotating assembly of this utility model includes a housing 9, a gear shaft 10, a main bevel gear 11, a driven bevel gear 12, a motor 13, and a roller assembly 14; as shown... Figure 1 , Figure 4 As shown, a circular box 9 with an open upper surface is horizontally embedded in the middle of the lower surface of the housing 1. The upper surface of the box 9 is coplanar with the inner bottom surface of the housing 1, and its lower surface is located above the horizontal plane where the lower end of the corresponding support leg 4 is located. A gear shaft 10 is vertically and coaxially arranged inside the box 9, and the diameter of the gear shaft 10 is smaller than the inner diameter of the box 9. The lower end of the gear shaft 10 is rotatably connected to the inner bottom surface of the box 9, and its upper end extends vertically upward into the interior of the housing 1 and is fixedly connected coaxially to the middle of the lower surface of the rotating plate 15. A driven bevel gear 12 is coaxially and fixedly mounted on the axle 10 relative to the inside of the housing 9, and the driven bevel gear 12 and the housing 9 are not interfered with each other. A motor 13 is horizontally mounted on one side of the driven bevel gear 12 relative to the inside of the housing 9. The fixed end of the motor 13 is screwed to the corresponding side of the housing 9, and its output end is horizontally mounted towards the driven bevel gear 12. It is connected to the driven bevel gear 12 through the meshing of the main bevel gear 11. Under the drive of the motor 13, the gear shaft 10 is rotated around its own axis, and the rotating plate 15 is rotated horizontally.

[0031] like Figure 1 , Figure 4 As shown, a number of roller sets 14 are connected to the inner bottom surface of the housing 1 and abut against the lower surface of the rotating plate 15. The roller sets 14 are coaxially arranged with the rotating plate 15 and are arranged without interfering with the gear shaft 10. Each roller set 14 is conical, with one end near the gear shaft 10 being the small end and the other end being the large end, so as to accommodate a smaller linear velocity near the gear shaft 10 when the rotating plate 15 rotates.

[0032] This invention provides a blowing assembly on the lower surface of the lifting plate 6 relative to each placement slot 17 of one of the placement plates 16, and a detection assembly on its lower surface relative to each placement slot 17 of the other placement plate 16. The desiccant pack, heated by the blowing assembly, is then rotated by the rotating assembly to be directly below the detection assembly for testing. Figures 1-5 As shown, a circular channel II 27 is coaxially embedded inside each placement plate 16 directly below each placement slot 17. Each channel II 27 is spaced apart directly below the corresponding placement slot 17, and its diameter is larger than the diameter of the corresponding placement slot 17. The outer circumferential surface of each channel II 27 is vertically turned upward and extends vertically out of the upper surface of the corresponding placement plate 16, ensuring that it is coaxially spaced and fitted onto the outside of the corresponding placement slot 17. Several through holes II 28 are also evenly distributed and vertically embedded at the bottom of each placement slot 17 of each placement plate 16. The upper end of each through hole II 28 is connected to the corresponding placement slot 17, and its lower end is connected to the corresponding channel II 27.

[0033] This utility model's blower assembly includes a heating box 18, a fan 19, a flexible hose 20, a pipe I 22, a cover I 21, a channel I 23, and a through hole I 24; as shown Figures 1-5 As shown, hollow cylindrical covers I21 are vertically fixed on the lower surface of the lifting plate 6 relative to each placement slot 17 of one of the placement plates 16. Each cover I21 is coaxially arranged with the corresponding placement slot 17, and its lower surface is open. The outer diameter of each cover I21 is larger than the outer diameter of the corresponding channel II 27, and its inner diameter is larger than the diameter of the corresponding placement slot 17 and smaller than the inner diameter of the corresponding channel II 27. A coaxially vertically embedded opening is also provided on the lower surface of each cover I21. Each annular channel I23 is not connected to the interior of the corresponding cover I21, and its upper end extends vertically upward beyond the upper surface of the corresponding cover I21; each channel I23 is coaxially arranged with the corresponding channel II27, and its inner and outer diameters are consistent with the inner and outer diameters of the corresponding channel II27; several through holes I24 are evenly distributed and inclinedly embedded on the inner circumferential surface of each cover I21, and each through hole I24 extends upward inclinedly outward and is connected to the corresponding channel I23;

[0034] like Figures 1-5 As shown, a fan 19 and a heating box 18 are provided on the upper surface of the housing 1 between the two electric push rods 5, and the fan 19 is connected to the heating box 18. A pipe 122 is also embedded in the lifting plate 6 at a position relative to the cover Ⅰ21. The lower end of the pipe 122 is divided into several branches, each corresponding to a channel Ⅰ23, and extends vertically downward from the lower surface of the lifting plate 6, and is sealed and connected to the upper end of the corresponding channel Ⅰ23. The upper end of the pipe 122 extends upward from the upper surface of the lifting plate 6, and is set without interfering with the corresponding electric push rod 5, and is sealed and connected to the lower end of the hose 20. The upper end of the hose 20 extends upward from the upper surface of the housing 1 and is sealed and connected to the output end of the fan 19. Then, the fan 19 blows hot air sequentially through the hose 20, the pipe 122, and the channel Ⅰ23 to the corresponding through hole Ⅰ24 to blow hot air into the inside of the cover Ⅰ21.

[0035] The detection assembly of this utility model includes a housing II 25 and a thermal imager 26; as shown... Figures 1-5 As shown, hollow cylindrical covers II 25 are vertically fixed on the lower surface of the lifting plate 6 relative to each placement slot 17 of the other placement plate 16. The inner and outer diameters of each cover II 25 are consistent with the inner and outer diameters of each cover I 21, and their heights are consistent with the heights of each cover I 21, ensuring that their heights are greater than the thickness of the desiccant pack. Each cover II 25 is coaxially arranged with the corresponding placement slot 17, and its lower surface is open. A thermal imager 26 is also installed on the lower surface of the lifting plate 6 relative to the interior of each cover II 25, and the thermal imager 26 is used to detect whether there is hot air inside the corresponding desiccant pack. In this invention, when the cover II 25 is placed on the clockwise path of the cover I 21, the rotating plate 15 is set to rotate clockwise, thereby rotating the desiccant pack after being heated horizontally to directly below the cover II 25 for detection.

[0036] The upper limit position of the lifting plate 6 of this utility model must ensure that each cover I 21 and each cover II 25 are disengaged from the corresponding placement plate 16, and its lower limit position must ensure that the lower surface of each cover I 21 and the lower surface of each cover II 25 are in close contact with the upper surface of the corresponding placement plate 16, and it must ensure that the lower end of each channel I 23 is coaxially connected with the upper end of the corresponding channel II 27 at this time.

[0037] The working principle of this utility model is as follows: First, the desiccant pack is placed in each placement slot 17 of one of the placement plates 16, and rotated under the drive of the rotating component to be directly below the cover I21; then, driven by the electric push rod 5, the lifting plate 6 moves vertically downward, and the lower surface of each cover I21 is in close contact with the upper surface of the corresponding placement plate 16, ensuring that each cover I21 covers the desiccant pack in the corresponding placement slot 17; then, the fan 19 blows hot air sequentially through the hose 20, pipe I22, and channel I23 to the corresponding through hole I24, and then blows hot air through the through hole I24 to the desiccant pack in the corresponding cover I21; at this time, the next batch of desiccant packs can be placed in each placement slot 17 of the previous placement plate 16 on the clockwise path;

[0038] Then, the lifting plate 6 moves vertically up and down to make the cover I 21 detach from the corresponding placement plate 16. Then, driven by the rotating component, the desiccant pack after being heated is rotated clockwise to the underside of the cover II 25. At this time, the next batch of desiccant packs to be tested rotates clockwise to the underside of the cover I 21. Then, driven by the electric push rod 5, the lifting plate 6 moves vertically downward and covers the desiccant packs in the corresponding placement slots 17 of each cover I 21 and each cover II 25.

[0039] At this time, hot air is blown into the desiccant pack in the corresponding housing I 21 by the fan 19; at the same time, the desiccant pack in the corresponding housing II 25 is observed by the thermal imager 26. If there is no hot air inside the desiccant pack, the desiccant pack will appear as a blue low-temperature color on the screen of the thermal imager 26. If hot air enters the desiccant pack, a red temperature color will be mixed in the blue low-temperature area, indicating that the desiccant pack is damaged. At the same time, the next batch of desiccant packs can be placed in each placement slot 17 of the previous placement plate 16 on the clockwise path.

[0040] The beneficial effects of this utility model are:

[0041] (1) This utility model, through the cooperation of heating box 18, fan 19, hose 20, pipe I 22, cover I 21, channel I 23, through hole I 24, channel II 27 and through hole II 28, can blow hot air onto the surface of the desiccant pack. Then, through the cooperation of rotating component, cover II 25 and thermal imager 26, it can observe whether there is hot air inside the desiccant pack, and thus determine whether the desiccant pack is damaged, thereby improving the accuracy of detection.

[0042] (2) This utility model can blow hot air in the cover I 21 while testing is carried out in the cover II 25. In addition, the next batch of desiccant packs can be placed in the placement slot 17 of the third placement plate 16, so that the three actions are carried out simultaneously. Then, the rotating components are used to form a production line testing operation, which improves work efficiency.

[0043] (3) The present invention facilitates the switching between detection and movement states by using the hydraulic cylinder 2, universal wheel 3 and outrigger 4 together, thereby improving the stability during detection.
