DETAILED DESCRIPTION

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0017] The following describes an embodiment of the present invention based on its overall structure.

[0018] A logistics box conveying device with a flipping function, such as Figure 1-Figure 7 As shown, it includes a U-shaped conveyor frame body 100, the upper ends of the U-shaped conveyor frame body 100 are connected to fixed drive rollers 110 through bearings on both sides, and the lower ends of the U-shaped conveyor frame body 100 are slidably connected to movable drive rollers 120 on both sides, and the outer walls of the two sets of fixed drive rollers 110 and the movable drive rollers 120 are sleeved with the same conveyor belt 130, and a top material assembly 200 is installed in the U-shaped conveyor frame body 100, and the top material assembly 200 is connected to the spray assembly 300, and the top of the U-shaped conveyor frame body 100 is located at the fixed positions on both sides of the conveyor belt 130. The U-shaped conveyor frame 100 is provided with a positioning assembly 400; the ejector assembly 200 includes two sets of rotating shafts 210 which are arranged on the rear side of the U-shaped conveyor frame 100, the rotating shafts 210 are connected to the rear side of the U-shaped conveyor frame 100 through bearings, and one end of the rotating shaft 210 located in the U-shaped conveyor frame 100 is fixedly connected to a turntable 220, and a movable column 230 is fixedly connected to the edge of the turntable 220 away from the rotating shaft 210, and the outer wall of the movable column 230 is movably connected to a movable frame 240, and a ejector rod 250 is fixedly connected to the top center of the movable frame 240. A top plate 260 is fixedly installed at the top of the rod 250, and a movable groove 150 is opened at the bottom end of the inner side walls of the U-shaped conveying frame body 100, and a sliding rod 160 is horizontally arranged in the movable groove 150. Both ends of the outer walls of the two groups of sliding rods 160 are slidably connected with sliders 170 matching the movable groove 150. Rollers 180 are installed on the upper and lower surfaces of each group of sliders 170. Slide grooves matching the rollers 180 are opened at the upper and lower ends of the movable groove 150. The rollers 180 are slidably connected to the slide grooves. One side of each group of sliders 170 is connected to the movable groove 150. Springs 190 are fixedly installed between the sides, and each group of springs 190 is sleeved on the outer wall of the slide rod 160. One end of a group of fixed transmission rollers 110 extends through the U-shaped conveying frame body 100 and is installed with a driving motor 140. The driving motor 140 is fixedly connected to the outer wall of the U-shaped conveying frame body 100 through a mounting seat. The outer walls of the two groups of rotating shafts 210 away from the turntable 220 and the output end of the driving motor 140 are fixedly sleeved with pulleys 3910, and the three pulleys 3910 are connected by belts 3920.

[0019] The operator starts the driving motor 140 through the controller to drive the fixed driving roller 110 to rotate, thereby driving the conveyor belt 130 to transmit. At this time, several groups of logistics boxes are transported on the conveyor belt 130 at equal intervals. The belt 3920 drives the two rotating shafts 210 to rotate synchronously, thereby driving the two turntables 220 to rotate, driving the movable column 230 to start circular motion, thereby driving the movable frame 240 to reciprocate in the vertical direction, and then driving the top rod 250 and the top plate 260 fixed thereto to reciprocate in the vertical direction. It is worth noting that there is a certain time difference between the up and down movement of the two groups of top rods 250 and the top plate 260. When the logistics box moves to the conveyor belt 130 section between the two groups of top plates 260, the conveyor belt 130 section located in front of the logistics box is first lifted up by the top plate 260. At this time, the logistics box is lifted up and tilted backwards, and then the conveyor belt 130 section located behind the logistics box is lifted up, just catching a part of the logistics box after it is flipped over. When the conveyor belt 130 is lifted up by the top plate 260, the mobile transmission roller 120 is pulled by the conveyor belt 130 and slides toward the middle position of the U-shaped conveyor frame body 100. The mobile transmission roller 120 is connected to the slider 170 through a bearing, and the rotation of the mobile transmission roller 120 itself is not affected during the movement. When the mobile transmission roller 120 drives the sliders 170 at both ends to slide on the slide bar 160 toward the middle position of the U-shaped conveyor frame body 100, the spring 190 will be further stretched. It should also be noted that the initial state of the spring 190 is a stretched state, so that the conveyor belt 130 is always in a taut state. At the same time, the friction between the slider 170 and the moving groove 150 is reduced by the installed roller 180, so that the mobile transmission roller 120 moves more stably and smoothly in the horizontal direction.

[0020] Please refer to Figure 2 , Figure 3 as well as Figure 6As shown, the spray assembly 300 includes a piston rod 310 fixedly connected to the center of the bottom end of the movable frame 240, the bottom end of the piston rod 310 is fixedly connected to a piston 320, the outer side of the piston 320 is sleeved with a piston cylinder 330, the bottom of the piston cylinder 330 is fixedly connected to a first connecting pipe 340, the other end of the first connecting pipe 340 is fixedly connected to a liquid storage tank 350, the liquid storage tank 350 is fixedly installed on the inner side wall of the U-shaped conveying rack body 100, the outer bottom end of the piston cylinder 330 is fixedly connected to a second connecting pipe 360, the second connecting pipe 360 ​​extends upward and is fixedly connected to A transverse tube 370 is fixedly connected to one side of the outer wall of the transverse tube 370 with equally spaced nozzles 380, each group of nozzles 380 is tilted and aligned with the bottom of the conveyor belt 130, a plurality of through holes 131 are provided on the surface of the conveyor belt 130, a plurality of groups of equally spaced first rollers 270 are installed on the upper surface of the top plate 260, a one-way valve is installed at one end of the first connecting tube 340 and the second connecting tube 360, a fixing frame 390 is fixedly installed on one side of the inner wall of the U-shaped conveying frame body 100, and the second connecting tube 360 ​​and the transverse tube 370 are fixedly supported by the fixing frame 390.

[0021] As the movable frame 240 reciprocates in the vertical direction, the piston rod 310 and the piston 320 fixed at the bottom are driven to reciprocate in the piston cylinder 330. When the piston rod 310 drives the piston 320 to move toward the top of the inner cavity of the piston cylinder 330, negative pressure is generated in the piston cylinder 330. At this time, the disinfectant is extracted from the liquid storage tank 350 in cooperation with the one-way valve. At this time, the disinfectant is transported to the piston cylinder 330 through the first connecting pipe 340. When the piston rod 310 drives the piston 320 to move toward the bottom of the inner cavity of the piston cylinder 330, In conjunction with the one-way valve, the disinfectant in the piston cylinder 330 is squeezed through the second connecting pipe 360 ​​and transported to the cross pipe 370, and finally sprayed out by a plurality of groups of nozzles 380 to spray the bottom of the conveyor belt 130, and in conjunction with a plurality of groups of through holes 131 opened on the surface of the conveyor belt 130, the surface of the logistics box is disinfected and sterilized, thereby achieving disinfection and sterilization of the bottom of the logistics box and the side in contact with the conveyor belt 130, so that the surface of the logistics box is thoroughly sterilized, and at the same time, in conjunction with the top material assembly 200, the cost of transportation and sterilization of the logistics box is greatly reduced.

[0022] Please refer to Figure 1 , Figure 2 as well as Figure 3 As shown, an inspection door 1910 is installed on the front side of the U-shaped conveying rack body 100, and the inspection door 1910 and the front side of the liquid storage tank 350 are both set as transparent glass. A liquid injection tube 3930 is fixedly connected to the upper end of the rear side of the liquid storage tank 350, and the other end of the liquid injection tube 3930 extends through to the rear side of the U-shaped conveying rack body 100.

[0023] The installation of the inspection door 1910 facilitates the subsequent maintenance or replacement of the device in the U-shaped conveyor rack body 100, and the inspection door 1910 and the front side of the liquid storage tank 350 are set as transparent glass, which is convenient for observing the operation of the internal device and the capacity of the disinfectant in the liquid storage tank 350. When the disinfectant is almost used up, disinfectant is added to the liquid storage tank 350 through the injection pipe 3930, so as not to affect the subsequent logistics box transportation and disinfection operations.

[0024] Please refer to Figure 5 and Figure 6 As shown, two groups of fixed base plates 280 are fixedly installed on one side of the inner wall of the U-shaped conveying frame body 100, and guide rods 290 are fixedly connected on both sides of the upper surface of each group of fixed base plates 280. The two ends of each group of movable frames 240 are sleeved on the outer walls of the two groups of guide rods 290 and are slidably connected thereto, and the piston cylinder 330 is fixedly installed on the upper surface of the fixed base plate 280.

[0025] The guide rod 290 is slidably connected to the movable frame 240 , so that the movable frame 240 moves more stably in the vertical direction.

[0026] Please refer to Figure 1 and Figure 7 As shown, the positioning assembly 400 includes a plurality of groups of U-shaped clamps 410 fixedly mounted on the top inner side of the U-shaped conveying frame body 100 and located on both sides of the conveyor belt 130, and a plurality of second rollers 420 are mounted on the upper and lower ends of the inner side of each group of U-shaped clamps 410, and each second roller 420 is in contact with the upper and lower surfaces of the conveyor belt 130.

[0027] By setting the positioning assembly 400, when the conveyor belt 130 is lifted up by the top plate 260, the positions except the lifted interval of the conveyor belt 130 are positioned to prevent other positions from being lifted up, causing the entire logistics box to slide backward during transportation, resulting in instability in the entire transportation process. At the same time, a plurality of second rollers 420 are abutted against the upper and lower surfaces of the conveyor belt 130, thereby reducing the friction force of the U-shaped clamp 410 on the conveyor belt 130.

[0028] During use, the operator starts the driving motor 140 through the controller to drive the fixed driving roller 110 to rotate, thereby driving the conveyor belt 130 to transmit. At this time, several groups of logistics boxes are transported on the conveyor belt 130 at equal intervals. The belt 3920 drives the two rotating shafts 210 to rotate synchronously, thereby driving the two turntables 220 to rotate, driving the movable column 230 to start circular motion, thereby driving the movable frame 240 to reciprocate in the vertical direction, and then driving the top rod 250 and the top plate 260 fixed thereto to reciprocate in the vertical direction. It is worth noting that there is a certain time difference between the up and down movement of the two groups of top rods 250 and the top plate 260. When the logistics box moves to the conveyor belt 130 section between the two groups of top plates 260, the conveyor belt 130 section on the front side of the logistics box is first lifted up by the top plate 260. At this time, the logistics box is lifted up and tilted backwards, and then the conveyor belt 130 section on the rear side of the logistics box is lifted up, just catching one side of the logistics box after it is flipped over. The two wheels 170 are connected to each other through the bearings 170, and the rotation of the two wheels 170 is not affected during the movement. When the two wheels 170 are connected to each other through the bearings 170, the rotation of the two wheels 170 is not affected. When the two wheels 170 are connected to each other through the bearings 170, the rotation of the two wheels 170 is not affected. When the two wheels 170 are connected to each other through the bearings 170, the rotation of the two wheels 170 is not affected. When the two wheels 170 are connected to each other through the bearings 170, the rotation of the two wheels 170 is not affected. When the two wheels 170 are connected to each other through the bearings 170, the rotation of the two wheels 170 is not affected. When the two wheels 170 are connected to each other through the bearings 170, the rotation of the two wheels 170 is not affected. When the two wheels 170 are connected to each other through the bearings 170, the rotation of the two wheels 170 is not affected.
