DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Refer to Figures 1 to 5As shown in the figure, the utility model provides a food packaging box punching machine, which includes: a fixed frame 1, a punching component 2, a positioning component 3 and a collection box 6. The fixed frame 1 is installed on the conveyor line of the carton, and an extension plate 11 is connected to the outside of the fixed frame 1. An adjusting cylinder 12 is installed at the upper end of the fixed frame 1. At the same time, the punching component 2 is slidably connected to the front and rear side plates of the fixed frame 1. The positioning component 3 is connected to the outer end of the extension plate 11. The positioning component 3 includes a driving shaft 32 rotatably connected between the extension plates 11. A connecting plate 33 is connected to the outside of the driving shaft 32. At the same time, a rotating plate 38 is connected to the outer wall of the connecting plate 33. A slot block 35 is connected to the lower end of the rotating plate 38. The collection box 6 is arranged on the lower side of the conveyor line, and a vibration component 4 is arranged on the outside of the collection box 6.

[0024] In this embodiment, the fixed frame 1, the punching component 2, the positioning component 3, the collection box 6, the vibration component 4 and the elastic telescopic rod 5 constitute the main structure of the food packaging box punching machine involved in this application.

[0025] Among them, limiting guide plates (not shown in the figure) are arranged on both sides of the involved roller conveyor line to achieve the guiding effect during the carton conveying process. Then, a set of photoelectric switches are installed on the lower side of the top plate of the fixed frame 1 to stop the conveyor line and start the punching mechanism after the carton enters the predetermined position.

[0026] Specifically, the lower end of the conveyor line is provided with legs, and a cross plate is arranged between the legs. The collection box 6 is placed on the upper side of the cross plate.

[0027] As Figure 1 and Figure 2 shown, the fixed frame 1 is set as an N-shaped frame structure, and through holes 13 are opened on the front and rear side plates of the fixed frame 1. The piston rod of the adjusting cylinder 12 is inserted into the inner side of the through hole 13. The punching component 2 includes a slider 22 slidably connected in the through hole 13. A punching cylinder 21 is installed on the outside of the slider 22. The piston rod end of the punching cylinder 21 is connected to a punching head 23.

[0028] Specifically, the slider 22 is set as a horizontally arranged T-shaped block structure, so that the up and down position sliding of the slider 22 is realized through the adjusting cylinder 12 and the through hole 13.

[0029] Specifically, the punching head 23 is set as a rectangular box structure, and arc chamfers are provided at the four corners of the rectangular box. The outer peripheral wall plate of the rectangular box is matched and inserted into the closed annular groove opened by the slot block 35, so as to punch down the cardboard in the covered area inside the punching head 23 and complete the punching action.

[0030] As Figure 1 、 Figure 3 and Figure 4As shown in the figure, one end of the drive shaft 32 is connected to a motor 31, and the motor 31 is fixed on the outer wall of the extension plate 11. The rotating plate 38 is provided with a structure of two vertically connected rectangular plates. A clamping cylinder 34 is installed inside the rotating plate 38. The piston rod of the clamping cylinder 34 slides through the rotating plate 38, and the outer end of the piston rod is connected to the slot block 35. The slot block 35 is provided with a rectangular block structure. A closed annular groove is opened on the outer side end face of the rectangular block. An air hole is opened at the bottom of the groove. The outside of the air hole is connected to a blowing pump 36 through an air pipe 37, and the blowing pump 36 is fixed inside the rotating plate 38.

[0031] Specifically, the two rectangular plates included in the rotating plate 38 are movably connected. That is, a synchronous cylinder is provided on the upper side of the rectangular plate in the horizontal position, and the lower piston rod of the synchronous cylinder is connected to the other vertical rectangular plate, so as to realize the up and down position adjustment of the slot block 35 installed on the vertical rectangular plate, so that its position corresponds to the position of the punching head 23 in the horizontal direction.

[0032] As a preferred embodiment, by setting the air hole, the air pipe 37 and the blowing pump 36, the relatively small shredded paper blocks partially embedded in the annular groove during the punching process are blown outwards, preventing accumulation from affecting the punching operation.

[0033] It should be noted that the annular groove on one side of the slot block 35 is similar to the structure of an operation annular runway and is not a regular circular groove structure.

[0034] It should be noted that since the open mouth of the cardboard box is much larger than the overall volume of the rotating plate 38, the rotating plate 38 can be inserted into the cardboard box without hindrance. Then, the slot block 35 is used to squeeze and fix the cardboard box wall from the inside out, preventing the phenomenon that the punching mechanism and the cardboard box wall move and rub against each other.

[0035] As Figure 1 and Figure 5 shown, clamping blocks 51 are provided on the outer side of the collection box 6. The outer ends of the clamping blocks 51 are connected to elastic telescopic rods 5, and the elastic telescopic rods 5 are located below the vibration assembly 4. The vibration assembly 4 includes a suspension rod 41. The lower end of the suspension rod 41 is connected to a guide sleeve 43. A horizontal vibration rod 42 is slidably connected in the guide sleeve 43. A spring 44 is sleeved on the outer side of the vibration rod 42. A baffle 45 is fixed on the outer side of the vibration rod 42. The outer side of the baffle 45 is connected to a telescopic vibrator 46. The spring 44, the baffle 45 and the telescopic vibrator 46 are all located on the same side of the guide sleeve 43.

[0036] Specifically, a pair of elastic telescopic rods 5 are provided, and the clamping blocks 51 are provided with an N-shaped block structure. When the clamping blocks 51 clamp the outer wall of the collection box 6, the four edges of the collection box 6 are clamped, so as to achieve a stable elastic clamping effect.

[0037] As a preferred embodiment, by providing the vibration assembly 4, it is convenient to vibrate and flatten the shredded paper blocks falling into the collection box 6, preventing overflow caused by excessive accumulation too quickly.

[0038] During use, place the open end of the folded cardboard box in the conveying direction of the conveyor line, convey it through the conveyor line, stop when it reaches the lower side of the fixing frame, and at the same time start the motor to drive the rotating plate to turn downward, so that the rotating plate is inserted into the inner side of the cardboard box from the open end of the cardboard box. Then start the clamping cylinder to drive the slot block to move outward and lean against the inner wall of the cardboard box, making it correspond to the punching plate outside the cardboard box and clamping and fixing it. Then start the punching cylinder to push the punching head from the outside towards the slot block to perform the punching operation.

[0039] The food packaging box punching machine of the present utility model can effectively solve the problems that the existing punching and positioning device for packaging box cardboard is not convenient for collecting the generated shredded paper blocks and cannot ensure the accurate entry of the cardboard box into the punching position. On the basis of the existing food packaging box punching machine technology, it is convenient to collect the shredded paper blocks generated by punching and at the same time ensures the accurate entry of the cardboard box into the punching position.
