[0035] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example

[0037] See also Figure 1-Figure 2 As shown, the purpose of this embodiment is to provide a processing packaging box device with a function of spraying preservatives, comprising a roller conveyor belt 1 for conveying packaging boxes, a support frame 11 is fixedly installed on the top of the roller conveyor belt 1, a mounting frame 12 is fixedly installed in the middle of the support frame 11, a fixed plate 2 is fixedly installed on the top of the roller conveyor belt 1, a movable plate 21 is arranged on the top of the fixed plate 2, a limiting assembly 22 is installed in the middle of the movable plate 21 and the fixed plate 2, and the limiting assembly 22 can make the movable plate 21 move left and right on the top of the roller conveyor belt 1, so as to limit the conveying of the packaging boxes;

[0038] A cleaning brush 3 is rotatably mounted on the top of the movable plate 21, a connecting plate 31 is mounted on the top of the cleaning brush 3, a telescopic assembly 32 is fixedly mounted on the outer side of the connecting plate 31, and the telescopic assembly 32 cooperates with the movable plate 21 to move the cleaning brush 3 left and right to adjust the position;

[0039] By extending and retracting the movable plate 21 through the limiting component 22, the packaging box transported on the roller conveyor belt 1 can be limited, so that the packaging box passes the outside of the cleaning brush 3 installed on the top of the movable plate 21, so that the cleaning brush 3 cooperates with the telescopic component 32 to extend and retract together with the movable plate 21, and the outer surface of the packaging box is cleaned, which is convenient for the subsequent spraying of preservatives on the packaging box.

[0040] After the packaging box is cleaned, a spray column 1 4 is installed on the top of the movable plate 21 , and a spray column 2 41 is installed on the bottom of the mounting frame 12 . The spray column 1 4 and the spray column 2 41 are used to spray preservatives on the packaging box after being cleaned by the brush 3 .

[0041] Two spray columns 1 4 are provided, and the two spray columns 1 4 are symmetrically distributed on the top of the two moving plates 21 , and cooperate with the spray column 2 41 to spray the preservative on the outer surface of the packaging box.

[0042] A spray column 1 4 and a spray column 2 41 are installed behind the cleaning brush 3. The spray column 1 4 is installed on the top of the movable plate 21 and can be adjusted left and right along with the movable plate 21. The two spray columns 1 4 and the spray column 2 41 at the bottom of the mounting frame 12 can spray preservatives on the outer surface of the cleaned packaging box to increase the antibacterial and waterproof effects of the packaging box and protect the items placed inside the packaging box.

[0043] It should be noted that both the spray column 1 4 and the spray column 2 41 are connected to the aqueous preservative, so that the preservative can pass into the spray column 1 4 and the spray column 2 41, and be sprayed out from the nozzles opened on the outside of the spray column 1 4 and the spray column 2 41. After the packaging box passes through the spray column 1 4 and the spray column 2 41, it can only be sprayed onto three surfaces. The packaging box can be circulated and transported, and the packaging box can be turned to achieve the effect of spraying the preservative on the outer surface of the packaging box. The preservative is an aqueous preservative with water as the solvent, which is relatively environmentally friendly, safe, and relatively less volatile.

[0044] First, considering how the limit assembly 22 adjusts the moving plate 21, Figure 3 Figure 4 , the specific structure of the limit assembly 22 is disclosed. The limit assembly 22 includes a sliding slot block 201 fixedly installed on the top of the fixed plate 2, a slider 202 is slidably installed inside the sliding slot block 201, the slider 202 is fixedly installed on the bottom of the movable plate 21, and a telescopic cylinder 203 is installed on the top of the fixed plate 2. The telescopic head of the telescopic cylinder 203 is fixedly installed on the outside of the movable plate 21. The telescopic cylinder 203 cooperates with the slider 202 to make the movable plate 21 move left and right in the sliding slot block 201 on the top of the fixed plate 2.

[0045] There are two fixed plates 2 and two movable plates 21 , which are symmetrically distributed on the top of the roller conveyor belt 1 . The two movable plates 21 extend and retract in the same direction to limit the position of the packaging boxes on the roller conveyor belt 1 .

[0046] Furthermore, by installing the fixed plate 2 on the top of the roller conveyor belt 1, the sliding slot block 201 can be fixedly installed on the top of the fixed plate 2, and the slider 202 fixedly installed on the bottom of the movable plate 21 is docked and installed into the inside of the sliding slot block 201, so that the movable plate 21 can move left and right in the sliding slot block 201 through the slider 202, and then the side of the movable plate 21 is fixedly connected through the telescopic head of the telescopic cylinder 203, so that the telescopic cylinder 203 can extend and retract the movable plate 21 through the control device, and limit the packaging box to the middle of the two movable plates 21 for transportation, so that the cleaning brush 3 can contact and clean the outer surface of the packaging box.

[0047] Secondly, considering the problem of how the cleaning brush 3 cleans the outer surface of the packaging box, Figure 5 and Figure 6 , the specific structure of the telescopic component 32 is disclosed. The telescopic component 32 includes a connecting rod 301 fixedly installed on the outside of the mounting frame 12, a connecting block 302 is sleeved on the outer surface of the connecting rod 301, a return spring 303 is installed on the outer surface of the connecting rod 301, one end of the return spring 303 is installed on the outside of the mounting frame 12, and the other side of the return spring 303 is installed on the outer surface of the connecting block 302. The connecting block 302 can be telescoped on the outer surface of the connecting rod 301 through the return spring 303.

[0048] The connecting block 302 is fixedly mounted on the outer side of the connecting plate 31 , and the telescopic assembly 32 cooperates with the moving plate 21 to enable the cleaning brush 3 to move left and right.

[0049] Furthermore, by rotatably mounting the bottom of the cleaning brush 3 to the top of the movable plate 21, and rotatably mounting the top to the bottom of the connecting block 302, and the connecting block 302 is sleeved on the outer surface of the connecting rod 301, the connecting block 302 can be contracted by the return spring 303 on the outer surface of the connecting rod 301, and the cleaning brush 3 can be stably moved and adjusted, so that the bristles of the cleaning brush 3 can clean the outer surface of the packaging box passing between the two movable plates 21, and remove dust and debris on the outer surface of the packaging box.

[0050] Again, considering that the packaging box is light in weight, when the cleaning brush 3 cleans the outer surface of the packaging box, the packaging box will stagnate. Figure 5 and Figure 7A special-shaped plate 1 5 and a special-shaped plate 2 51 are respectively installed on the front and back of the connecting block 302, and a guide wheel 1 52 and a guide wheel 2 53 are rotatably installed on the top of the special-shaped plate 1 5 and the special-shaped plate 2 51, respectively. A driving motor 54 is installed at the bottom of the connecting block 302, and the driving motor 54 connects the guide wheel 1 52 and the guide wheel 2 53 through a crawler track, so as to drive the guide wheel 1 52 and the guide wheel 2 53 to rotate.

[0051] Two cleaning brushes 3 and two telescopic components 32 are provided, and the two cleaning brushes 3 and the two telescopic components 32 are symmetrically distributed on both sides of the mounting frame 12 to clean both sides of the outer surface of the packaging box conveyed on the roller conveyor belt 1.

[0052] Furthermore, by installing guide wheel 1 52 and guide wheel 2 53 on the front and back sides of the connecting block 302, guide wheel 1 52 and guide wheel 2 53 can be connected by a drive motor 54 through a track, so that the drive motor 54 can start to drive guide wheel 1 52 and guide wheel 2 53 to rotate, so that after the packaging box enters between the two movable plates 21, guide wheel 1 52 first contacts the side of the packaging box, and guide wheel 1 52 rotates to push the packaging box forward, so that the packaging box passes through the cleaning brush 3 for cleaning, and guide wheel 2 53 is located behind the cleaning brush 3 to continue to transport the packaging box, so that the packaging box can pass between the two cleaning brushes 3 for cleaning, thereby avoiding the situation where the packaging box stagnates.

[0053] Finally, considering that the top of the box also needs to be cleaned, Figure 5 A transverse cleaning brush 6 is provided at the bottom of the mounting frame 12 , and telescopic rods 61 are inserted at both ends of the transverse cleaning brush 6 . The two telescopic rods 61 are installed in the middle of the two telescopic components 32 to install the transverse cleaning brush 6 .

[0054] By installing the telescopic rod 61 between the two connecting blocks 302 and inserting the transverse cleaning brush 6 on the outer surface of the telescopic rod 61, the transverse cleaning brush 6 can be on the top of the packaging box to clean the top of the packaging box, and the telescopic rod 61 can ensure that the cleaning brushes 3 and the movable plate 21 on both sides can move left and right normally.

[0055] In summary, the working principle of this solution is as follows:

[0056] When processing the packaging box, the packaging box is transported by the roller conveyor belt 1, the control component monitors the moving position of the packaging box, and telescopically adjusts the position of the moving plate 21 by the telescopic cylinder 203, so that the packaging box can enter the middle of the two moving plates 21, and at the same time, the guide wheels 1 52 and the guide wheels 2 53 on both sides of the mounting frame 12 pull the connecting block 302 through the cleaning brush 3, so that the guide wheels 1 52 and the guide wheels 2 53 are in contact with the two sides of the packaging box and rotate, and the packaging box is stably transported to pass through the cleaning brush 3 for cleaning;

[0057] After the packaging box is conveyed by the guide wheel 1 52 and the guide wheel 2 53 and the two connecting plates 31 adjust their positions, the cleaning brush 3 also moves accordingly, so that the cleaning brush 3 can clean the outside of the packaging box limited to the middle of the two movable plates 21, and the horizontal cleaning brush 6 can clean the top of the packaging box, thereby achieving the effect of cleaning the debris and dust on the outer surface of the packaging box;

[0058] After cleaning the outer surface of the packaging box, it continues to be transported to the two injection columns 1 4 and 41 between the two connecting plates 31, so that the aqueous preservative is injected into the injection columns 1 4 and 41, and sprayed out from the injection ports opened on the outside of the injection columns 1 4 and 41 to spray the preservative on the outer surface of the packaging box, thereby increasing the antibacterial and waterproof effects of the packaging box and providing anti-corrosion protection for the items placed inside the packaging box.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
