[0027] See also Figure 1-6 The present invention provides a technical solution: a plasma comprehensive disinfection device for a transport box, comprising a box conveying device and a box disinfection mechanism; the box conveying device 1 comprises a plurality of conveying rollers connected to each other by transmission, the conveying rollers are installed on a conveying frame, and a protective cover 2 is installed above the conveying frame; the disinfection component comprises a left disinfection component 3, a right disinfection component 4 and an upper disinfection component 5 installed inside the protective cover 2, the upper disinfection component 5 is connected to a lifting cylinder 21, and a box turning mechanism is installed on the box conveying device 1;

[0028] The box flipping mechanism includes a flipping cylinder 7, a transmission bar 6 is sleeved on the circumferential outer wall of the flipping cylinder 7, a plurality of transmission teeth 23 are arranged in a ring array on the outer wall of the transmission bar 6, a transmission wheel 8 is arranged on one side of the bottom end of the transmission bar 6, meshing teeth 9 meshing with the transmission teeth 23 are arranged on the circumferential outer wall of the transmission wheel 8, and the transmission wheel 8 is connected to a transmission motor 10.

[0029] Furthermore, two groups of the left disinfection components 3 and the right disinfection components 4 are provided, and are respectively installed on the left and right inner walls of the protective cover 2.

[0030] Furthermore, the upper disinfection component 5 is installed on the upper part of the protective cover 2, and there are two groups of upper disinfection components 5, which are respectively arranged on the front and rear sides of the protective cover 2.

[0031] Furthermore, the flip cylinder 7 is installed between the two groups of upper disinfection components 5, and the left and right sides of the flip cylinder 7 are respectively provided with a box inlet 11 and a box outlet 12.

[0032] Furthermore, the length of the transmission bar 6 is half the length of the circumferential outer wall of the turning cylinder 7 .

[0033] Furthermore, support brackets 13 are installed on both left and right sides of the bottom of the turning cylinder 7 , and guide wheels 14 are installed on the support brackets 13 , and the guide wheels 14 are rotatably connected to the outer wall of the turning cylinder 7 .

[0034] Furthermore, four limit clamping plates 15 with an L-shaped cross section are arranged on the circumferential inner wall of the turning cylinder 7. When the box enters the turning cylinder 7, the four limit clamping plates 15 are respectively clamped at the four peripheral corners of the box.

[0035] Furthermore, a plurality of lifting baffles 16 are installed at equal intervals on the box conveying device 1 , a crank connecting rod 17 is connected to the bottom of the lifting baffle 16 , and a lifting motor 18 is connected to the bottom end of the crank connecting rod 17 .

[0036] Furthermore, limit plates 19 with an "L"-shaped cross-section are arranged on the left and right sides of the lifting baffle 16. The two limit plates 19 are symmetrically arranged on the mounting plate 20. The left and right side walls of the limit plates 19 are slid up and down in the cavity formed by the two limit plates 19 and the mounting plate 20. A proximity switch 22 is installed on the mounting plate 20.

[0037] Furthermore, the main body of all disinfection components is plasma. A single positive and negative electrode of the plasma generates plasma after the pulse, but a single plasma cannot disinfect a large area. Therefore, multiple plasmas can be arranged and combined into a surface to achieve sufficient disinfection effect.

[0038] Working principle: When the equipment is actually used, the box is horizontally transported through the box conveying equipment 1. During the box transportation process, its outer side wall is disinfected by the upper disinfection component 5, the left disinfection component 3 and the right disinfection component 4 respectively. Among them, the upper disinfection component 5 is driven up and down by the lifting cylinder 21 to achieve the purpose of adjusting the height.

[0039] In order to ensure the disinfection effect and realize comprehensive disinfection of the box, this scheme installs a box flipping mechanism on the box conveying equipment 1, so that during the horizontal transmission of the box, the box can enter the flipping cylinder 7 horizontally under the action of the conveying roller, and the transmission motor 10 drives the transmission wheel 8 to rotate, and the meshing transmission connection between the meshing teeth 9 on the transmission wheel 8 and the transmission teeth 23 on the transmission bar 6 drives the flipping cylinder 7 to rotate 180°, so that the box in the flipping cylinder 7 is synchronously flipped 180° and then falls back onto the transmission roller at the box outlet 12, and the top wall of the box after flipping is disinfected by the upper disinfection component 5 on the rear side of the protective cover 2, so as to achieve the purpose of comprehensive disinfection of the box.

[0040] The multiple lifting baffles 16 installed on the conveying equipment are lifted and lowered under the action of the lifting motor 18 and the crank connecting rod 17, and are used to limit the disinfection of multiple transfer boxes on the conveying equipment in batches to prevent multiple boxes from piling up and affecting the disinfection effect and efficiency.

[0041] In this embodiment, the turning cylinder 7 is driven to rotate 180° through the meshing transmission connection between the meshing teeth 9 on the transmission wheel 8 and the transmission teeth 23 on the transmission bar 6 .

[0042] In actual use, based on the above valve box flipping mechanism, the two guide wheels 14 at the bottom of the flip cylinder 7 can also be set as a gear structure, the guide wheel 14 is connected to a motor, and a rack group meshing and transmission connected with it is provided on the outer wall of the flip cylinder 7. The meshing transmission connection between the guide wheel 14 with the gear structure and the rack group drives the flip cylinder 7 to achieve flipping movement. A proximity switch is installed on the flip cylinder 7 to accurately control the flip angle of the flip cylinder 7 through the signal connection with the motor (see Figure 6 ).

[0043] It is worth noting that: the present solution provides a preferred driving mode for the flip cylinder 7, and various changes, modifications, substitutions and variations can be made to these embodiments (driving mode for the flip cylinder 7) without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.

[0044] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
