The interior of the slide groove 320 is connected to the arc block 316 through a spring 319. An L-shaped exhaust hole 317 is provided inside the arc block 316. The L-shaped exhaust hole 317 opens downward. The cold air pipe 318 is inserted into the exhaust hole 317 to leave a certain space for the arc block 316 to shrink. When the folded cardboard 5 contacts the arc block 316, the spring 319 is compressed and the arc block 316 shrinks. When the cardboard 5 falls, the arc block 316 will reset. At this time, the cooler works, and the cold air passes through the cold air pipe 318 and the L-shaped exhaust hole 317 to cool the adhesive at the fold between the cardboard 5 and the foam box 6, and the air is cooled from the attached Figure 2 It can be clearly seen that the finished product is made by folding the cardboard 5 and sticking it to the bottom of the foam box 6. Therefore, the bottom width and length of the finished product are slightly larger, leaving a gap to facilitate cooling, accelerate cooling efficiency, and improve work efficiency. The width and length of the folded cardboard 5 match the cooling chamber 313.

The cooling chamber 313 shapes it and pushes it out through the next finished product.

[0031] The dispensing mechanism 2 includes a conveyor frame 21, on which a glue box 28 is fixedly mounted. The glue box 28 is filled with adhesive. Both sides of the glue box 28 are connected to a delivery pipe 29 via a pump body. The ends of the two delivery pipes 29 are connected by a hose 212. A glue head 213 is fixedly mounted at the bottom of the hose 212. A cylinder 214 is vertically mounted on the hose 212. A pressure plate 215 is fixedly mounted on the end of the piston rod of the cylinder 214. A conveyor belt 22 is provided on the conveyor frame 21.

When the cardboard 5 passes under the rubber hose 212 and the glue head 213, the glue head 213 evenly dispenses glue on the surface of the cardboard 5. While dispensing glue, cylinder 4 214 will drive the pressing plate 215 to descend, fix the cardboard 5, and then transport it to the L-shaped folding rail 312.

[0032] A fifth cylinder 216 is fixedly mounted on the conveyor frame 21. The fifth cylinder 216 is located above the glue box 28. A second limit plate 217 is fixedly mounted on the end of the piston rod of the fifth cylinder 216. A third cylinder 210 is fixedly mounted on the conveyor frame 21. The third cylinder 210 is located on one side of the forming mechanism 3. A first limit plate 211 is fixedly mounted on the end of the piston rod of the third cylinder 210. The arrangement of the first limit plate 211 and the second limit plate 217 ensures a single conveyance at each time, preventing the simultaneous conveyance of too many sheets of paperboard 5, which could cause equipment chaos.

[0033] The feeding mechanism 1 includes a feeding frame 11, on which a drive motor 12 is fixedly mounted. A reducer 13 is fixedly mounted on the output shaft of the drive motor 12. The reducer 13 is connected to a reducer 2 17 via a transmission shaft 16. A threaded sleeve 14 is rotatably connected to each of the reducers 13 and 17. The threaded sleeve 14 is rotatably connected to the feeding frame 11. A threaded rod 15 is rotatably connected within the threaded sleeve 14. The top of the threaded rod 15 is rotatably connected to a placement plate 18. A displacement sensor and guide wheels are also mounted on the feeding frame 11. Cardboard 5 is manually or robotically placed on the placement plate 18. The guide wheels guide the conveyed cardboard 5. The displacement sensor measures the distance. The drive motor 12 is then controlled to operate, synchronously driving the reducer 13 and reducer 2 17 to rotate, which in turn drives the threaded sleeve 14, thereby driving the threaded rod 15, which in turn drives the placement plate 18 up and down, thereby adjusting the height of the placement plate 18.

[0034] The working principle of the present invention is as follows: a cardboard 5 is placed on the placement plate 18 manually or by a robot, the conveyed cardboard 5 is guided by a guide wheel, the distance is measured by a displacement sensor, and then the drive motor 12 is controlled to work, synchronously driving the reducer 13 and the reducer 2 17 to rotate, thereby driving the threaded sleeve 14 to rotate, thereby driving the threaded rod 15 to rotate, pushing the placement plate 18 up and down, and then adjusting the height of the placement plate 18;

[0035] Then, the cylinder 1 24 is started to push the cylinder 2 25, the cross plate 26 and the suction cup 27 to move horizontally above the cardboard 5. Then, the cylinder 25 is driven to drive the suction cup 27 to descend, sucking the cardboard 5 and conveying it to the conveyor belt 1 22. When the cardboard 5 passes under the glue hose 212 and the glue head 213, the glue head 213 evenly dispenses glue on the surface of the cardboard 5. At the same time, the cylinder 4 214 will drive the pressing plate 215 to descend, fix the cardboard 5, and then convey it to the L-shaped folding rail 312.

[0036] The foam box 6 is placed on the horizontal frame 39 manually or by a robot. The cylinder 7 36 drives the clamping plate 35 to clamp the foam box 6 and fix it. The cylinder 6 32 is driven to drive the cylinder 7 36 to move, thereby driving the foam box 6 to the top of the cardboard 5. At this time, the cylinder 8 310 is driven to drive the pressing frame 311 to descend. Through the setting of the L-shaped folding rail 312, the foam box 6 exerts a downward force on the cardboard 5, folds the four sides of the cardboard 5, and bonds it to the foam box 6. Then, the cardboard 5 falls from the forming channel into the cooling chamber 313 and is stuck. The cooling chamber 313 shapes its limit, and when the folded cardboard 5 contacts the arc block 316, the spring is compressed. 319, the arc block 316 contracts. When the cardboard 5 falls, the arc block 316 will reset. At this time, the cooler works, and the cold air passes through the cold air pipe 318 and the L-shaped exhaust hole 317 to cool the adhesive at the fold between the cardboard 5 and the foam box 6, thereby accelerating the cooling efficiency and improving the working efficiency. The width and length of the folded cardboard 5 match the cooling chamber 313. Under the action of friction, it will not fall downward, and a certain sealing can be generated, thereby improving the cooling effect. The next finished product is pushed down and falls onto the conveyor belt 2 4 for transportation. The entire equipment has a high degree of automation, which can reduce manpower and improve the working efficiency of the equipment.

[0037] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention.
