The output end of the electric push rod 317 is rotatably connected to one end of the connecting rod 316. When it is necessary to control the rotation of the connecting pipe 304 and the spray pipe, first start the electric push rod 317 to drive the connecting rod 316 to operate. The connecting rod 316 drives the turntable 315 to rotate. The turntable 315 drives the rotating shaft 307, causing the rotating shaft 307 to rotate along the inner wall of the fixing base 306. The rotating shaft 307 drives the connecting pipe 304 and the spray pipe to rotate. By setting the above structure, the effect of automatically controlling the rotation of the spray pipe is achieved.

A sliding rod 320 is slidably connected to the inner wall of the arc-shaped hole 319. One end of the sliding rod 320 is fixedly connected to one end of the connecting pipe 304. When the connecting pipe 304 rotates, the sliding rod 320 fixed on the connecting pipe 304 will slide along the inner wall of the arc-shaped hole 319. Since the angle of the arc-shaped hole 319 is limited, the rotation angle of the connecting pipe 304 and the spray pipe can be limited.

[0031] In an embodiment of the present invention, please refer to Figure 5 , the conveying and air-drying assembly 4 includes a connecting frame 41 and a chain 44. The connecting frame 41 is fixedly connected to the inner wall of the cleaning tank 1. A plurality of conveying rollers 42 are rotatably connected to the inner wall of the connecting frame 41. A gear 43 is fixedly connected to the arc surface of the conveying roller 42. The chain 44 meshes with a plurality of gears 43. One side of the outer wall of the connecting frame 41 is fixedly connected with a driving motor 45. The driving motor 45 is fixedly connected to one end of one of the conveying rollers 42. Two support plates 46 are fixedly connected to the outer wall of the connecting frame 41. A blower 47 is fixedly connected to one side of the two support plates 46 close to each other. By setting the conveying and air-drying assembly 4, after the foam box is cleaned, the foam box can be automatically moved out of the cleaning tank 1 and air-dried, further improving the working efficiency of the cleaning equipment. Two reinforcing ribs 48 are fixedly connected to the lower surface of the connecting frame 41. One side of the reinforcing rib 48 is fixedly connected to the cleaning tank 1. By setting the reinforcing rib 48, the connection strength between the connecting frame 41 and the cleaning tank 1 can be improved; In an embodiment of the present invention, please refer to Figure 6 , two flipping assemblies 6 are provided on the outer wall of the connecting frame 41. The flipping assembly 6 includes two auxiliary plates 61. One side of the auxiliary plate 61 is fixedly connected to the outer wall of the connecting frame 41. A connecting shaft 62 is rotatably connected to one side of the two auxiliary plates 61 close to each other. A flipping cylinder 63 is fixedly connected to the arc surface of the connecting shaft 62. A rectangular groove 64 is formed in the arc surface of the flipping cylinder 63. Air bags 67 are respectively arranged on the inner sides of the two groove walls of the rectangular groove 64. The air bags 67 are connected to an air pump through pipelines; one side of the air bag 67 is connected to the groove wall of the rectangular groove 64 by gluing, and the other side contacts the foam box after inflation to clamp the foam box; One side of one of the auxiliary plates 61 is fixedly connected with a support ring 65. A motor 66 is fixedly connected to the inner wall of the support ring 65. The output end of the motor 66 is fixedly connected to one end of the connecting shaft 62. By setting the flipping assembly 6, during the movement of the foam box on the conveying roller 42, the flipping cylinder 63 can flip the foam box by means of the rectangular groove 64, so that the opening of the foam box faces downward, enabling the liquid remaining inside the foam box to flow out, thus facilitating the next air-drying operation of the foam box.

[0032] Infrared light-emitting and receiving switches 7 are symmetrically arranged on the connecting frame 41 between the two flipping assemblies 6. An ultraviolet sterilization device 8 is arranged below the conveying roller 42 and at the gap between the conveying rollers 42. The ultraviolet sterilization device 8 is electrically connected to the infrared light-emitting and receiving switch 7. When the foam box is flipped between the two flipping assemblies, the infrared light-emitting and receiving switch is triggered, thereby turning on the ultraviolet sterilization device to sterilize the inside of the foam box.

[0033] The working principle of a cleaning device for the interior of a foam box provided by the present invention is as follows: When it is necessary to use this cleaning device to clean the foam box, first place the foam box to be cleaned inside the cleaning box 1, and then start the delivery pump inside the water storage tank 301, so that the liquid inside the water storage tank 301 sequentially flows along the corrugated pipe 303 and the connecting pipe 304 to reach the inside of the spray pipe and is ejected from the inside of the spray pipe. At the same time, the operator can drive the lead screw 309 to rotate by the automatic servo motor 312. The lead screw 309 drives the ear plate 308 to move, the ear plate 308 drives the fixed seat 306, and the fixed seat 306 drives the connecting pipe 304 and the spray pipe to move, so that the spray pipe can be translated. When it is necessary to rotate the spray pipe, first start the electric push rod 317 to drive the connecting rod 316 to operate. The connecting rod 316 drives the turntable 315 to rotate, the turntable 315 drives the rotating shaft 307, so that the rotating shaft 307 rotates along the inner wall of the fixed seat 306, and the rotating shaft 307 drives the connecting pipe 304 and the spray pipe to rotate. Through the above steps, the spray pipe can be translated and rotated during the process of spraying the cleaning liquid, expanding the cleaning range. Finally, the operator can thoroughly clean the interior of the foam box by continuously controlling the forward and reverse operation of the servo motor 312 and the electric push rod 317. Among them, when the fixed seat 306 moves, the positioning plate 313 fixed on the fixed seat 306 will move along the arc surface of the positioning rod 314, thereby improving the stability of the fixed seat 306 during the moving process. In addition, when the connecting pipe 304 rotates, the slide bar 320 fixed on the connecting pipe 304 will slide along the inner wall of the arc-shaped hole 319. Since the angle of the arc-shaped hole 319 is limited, the rotation angle of the connecting pipe 304 and the spray pipe can be limited.

[0034] When it is necessary to perform transportation, disinfection, and air-drying operations on the cleaned foam box, first start the drive motor 45 to drive one of the conveyor rollers 42 to rotate. This conveyor roller 42 will drive the other conveyor rollers 42 to rotate by means of the gear 43 and the chain 44, so that several conveyor rollers 42 can rotate synchronously along the inner wall of the connecting frame 41. During the rotation of the conveyor roller 42, the cleaned foam box will be moved out of the inside of the cleaning box 1. When the foam box moves below the blower 47, stop the operation of the drive motor 45, and then start the blower 47 to perform the air-drying operation on the foam box. Among them, by setting the reinforcing rib 48, the connection strength between the connecting frame 41 and the cleaning box 1 can be improved.

[0035] When the foam box needs to be flipped during the process of moving on the conveying roller 42, first start the motor 66 to drive the connecting shaft 62 to rotate. The connecting shaft 62 drives the flipping cylinder 63, so that the flipping cylinder 63 rotates continuously. When the foam box is conveyed to the flipping cylinder 63 and is in the rectangular groove 64 on the arc surface of the flipping cylinder 63, it is controlled by an external electrical control system. The airbag is inflated through an air pump, so that the airbag just clamps the foam box without damaging the fullness of the foam box and flips the foam box, enabling the foam box to be flipped 180 degrees, so that the cleaning liquid remaining inside the foam box can be poured out. At the same time, the opening of the foam box that has been flipped 180 degrees faces downward, and blocks the radiation path of the infrared radiation switch, thereby triggering the ultraviolet sterilization device electrically connected to the infrared radiation switch to work and disinfect the inside of the foam box. After that, the airbag of this set of flipping components deflates, and another set of flipping components 6 clamps the foam box again, making the mouth of the foam box face upward.

[0036] The circuits and controls involved in the present invention are all prior arts and will not be elaborated here too much.

[0037] What is described in the above specification is only the specific implementation manner of the present invention. Various examples do not constitute a limitation to the essence of the present invention. Those of ordinary skill in the art can make modifications or deformations to the previously described specific implementation manner after reading the specification, without departing from the essence and scope of the invention.
