DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 , Figure 2 As shown, a punching device for producing packaging cartons includes a workbench 1, a frame 2 is fixedly connected to the upper surface of the workbench 1 near the left and right sides, a punching mechanism 3 is fixedly connected to the lower surface of the inner cavity of the workbench 1, a storage box 4 is fixedly connected to the upper side of the punching mechanism 3, a plurality of collecting tubes 5 distributed as needed are fixedly connected to the upper surface of the storage box 4, and a placing mechanism 6 is fixedly connected to the upper surface of the workbench 1.

[0028] It should be noted that the storage box 4 is connected to the inner side of the collecting tube 5 , and the side wall of the collecting tube 5 is relatively thick and is used to support the cardboard, and the cut materials fall into the inner side of the storage box 4 .

[0029] like Figure 2-Figure 4 As shown, the punching mechanism 3 includes a first motor 31, the lower surface of the first motor 31 is fixedly connected to the middle part of the lower surface of the inner cavity of the workbench 1 near the right side, the output end of the first motor 31 is fixedly connected to the first crankshaft 32, the left end of the first crankshaft 32 is rotatably connected to the left side of the inner cavity of the workbench 1 near the bottom, and there are three first crankshafts 32 evenly distributed in front and back, the outer walls of the four first crankshafts 32 are rotatably connected to a number of evenly distributed first connecting rods 33, the upper end of the first connecting rod 33 is rotatably connected to a top platform 34, the outer side of the top platform 34 is movably sleeved on the inner side of the workbench 1, and the lower surface of the storage box 4 is fixedly connected to the middle part of the upper surface of the top platform 34.

[0030] It should be noted that the first motor 31 drives the first crankshaft 32 to rotate. The shape of the first crankshaft 32 is a "X" shape. When the first crankshaft 32 rotates, it drives the lower end of the first connecting rod 33 to move up and down, thereby causing the top platform 34 to move up and down.

[0031] like Figure 3 , Figure 4 As shown, the outer walls of the three first crankshafts 32 are fixedly connected to the positions near the left ends thereof with first sprockets 35 , and the side surfaces of two adjacent first sprockets 35 are meshingly connected with first chains 36 , and two first chains 36 are distributed front and back.

[0032] It should be noted that when the first crankshaft 32 located in the middle rotates, the first sprocket 35 located in the middle rotates, and relying on the first chain 36, all the first sprockets 35 rotate synchronously in the same direction, thereby making the three first crankshafts 32 rotate synchronously, causing the storage box 4 to be subjected to a greater thrust, thereby preventing a single first crankshaft 32 from being unable to withstand the gravity of the top platform 34, resulting in damage to components.

[0033] like Figure 3 , Figure 4 As shown, the upper side of the frame 2 is rotatably connected to a punching assembly 37, and the punching assembly 37 includes a second crankshaft 371, and the left and right ends of the second crankshaft 371 are rotatably connected to the bosses in the middle of the upper side of the frame 2 near the left and right sides, and the outer wall of the second crankshaft 371 is rotatably connected to a plurality of evenly distributed second connecting rods 374, and the lower end of the second connecting rod 374 is rotatably connected to a base plate 375, and the outer wall of the first crankshaft 32 located in the middle and the outer wall of the second crankshaft 371 near the left end are fixedly connected to a second sprocket 372, and the side of the second sprocket 372 is meshedly connected to a second chain 373.

[0034] It should be noted that when the first crankshaft 32 located in the middle rotates, it drives the second sprocket 372 located in the middle to rotate, and relies on the second chain 373 to drive the second crankshaft 371 to the east. The shape of the second crankshaft 371 is consistent with the shape of the first crankshaft 32, but the state of the second crankshaft 371 and the first crankshaft 32 are symmetrical up and down, so when the second crankshaft 371 rotates, it drives the upper end of the second connecting rod 374 to move up and down, and then drives the base plate 375 to move up and down. At the same time, when the top platform 34 moves up, the base plate 375 moves down, and vice versa.

[0035] like Figure 3 As shown, a plurality of cutting heads 377 distributed as required are fixedly connected to the lower surface of the base plate 375 , and the number and position of the cutting heads 377 are consistent with the number and position of the collecting tubes 5 .

[0036] It should be noted that the cutting head 377 is used to punch holes in the cardboard, and the collecting tube 5 and the cutting head 377 move toward each other, thereby increasing the cutting force of the cutting head 377 .

[0037] like Figure 3 As shown, four rectangularly distributed limiting rods 376 are fixedly connected to the upper surface of the base plate 375 near the front and rear sides, and the outer walls of the limiting rods 376 are movably sleeved in the sleeve holes on the upper wall of the frame 2 near the front and rear sides.

[0038] It should be noted that the limiting rod 376 is used to limit the state of the base plate 375 so that the base plate 375 is always in a horizontal state.

[0039] like Figure 5 , Figure 6 As shown, the placement mechanism 6 includes a second motor 61, the lower surface of the second motor 61 is fixedly connected to the upper surface of the workbench 1 near the middle front position on the right side, the output end of the second motor 61 is fixedly connected to a transmission rod 62, the upper surface of the workbench 1 near the left and right sides is fixedly connected to a slide 63, the outer wall of the transmission rod 62 is rotatably connected to the middle of the side of the slide 63, and two transmission rods 62 are symmetrically distributed on the slide 63 in the front and back, the outer walls of the two transmission rods 62 are fixedly connected to the positions near the left and right ends, and the sides of the gears 65 are close to the side of the slide 63, and the sides of the front and rear gears 65 are meshed and connected together.

[0040] It should be noted that the second motor 61 drives the transmission rod 62 located at the front side to rotate, and when the transmission rod 62 rotates, the adjustment gear 65 rotates, and the slides 63 on the front and rear sides are meshed and connected together so that the two transmission rods 62 move synchronously in opposite directions.

[0041] like Figure 5 , Figure 6 As shown, the upper side of the slide 63 is slidably connected to a placement rack 68, and the outer walls of the two transmission rods 62 are fixedly connected to winding wheels 64 near the left and right ends, and the winding wheels 64 are located on the outside of the slide 63, and the inner sides of the front and rear winding wheels 64 located on the same side are wrapped with a traction rope 67, and the left and right sides of the placement rack 68 are rotatably connected to fixed pulleys 66 near the front and rear ends, and the lower side of the traction rope 67 is overlapped on the upper side of the front and rear fixed pulleys 66 located on the same side.

[0042] It should be noted that the traction rope 67 extends from the lower side of the winding wheel 64 located on the front side, and the traction rope 67 extends from the upper side of the winding wheel 64 located on the rear side, so that when the winding wheels 64 on the front and rear sides rotate, one side releases the traction rope 67 and the other side tightens the traction rope 67, causing the placement rack 68 to slide on the upper side of the slide 63. The upper side of the slide 63 is provided with two front-to-back symmetrical placement grooves for placing cardboard for cartons.

[0043] The working principle of the utility model is as follows: first, the second motor 61 drives the transmission rod 62 located at the front side to rotate, and when the transmission rod 62 rotates, the gear 65 is adjusted to rotate, and the slides 63 on the front and rear sides are meshed and connected together so that the two transmission rods 62 move synchronously in opposite directions, and the traction rope 67 extends from the lower side of the winding wheel 64 located at the front side, and the traction rope 67 extends from the upper side of the winding wheel 64 located at the rear side, so that when the winding wheels 64 on the front and rear sides rotate, one side releases the traction rope 67, and the other side tightens the traction rope 67, so that the placement rack 68 slides on the upper side of the slide 63, and the upper side of the slide 63 is provided with two symmetrical placement grooves for placing cardboard for cartons, and the winding is driven by the second motor 61. The wheel 64 rotates, so that the placement rack 68 moves on the slide 63, so that the placement rack 68 can alternately place its upper half area just below the punching position, and the other side is the punched cardboard. The device provides two workstations on the front and back sides, and the punching and placement operations do not affect each other, which greatly improves the work efficiency. Finally, the first motor 31 drives the first crankshaft 32 to rotate. The shape of the first crankshaft 32 is a "J" shape. When the first crankshaft 32 rotates, it drives the lower end of the first connecting rod 33 to move up and down, thereby causing the top platform 34 to move up and down. When the first crankshaft 32 located in the middle rotates, the first sprocket 35 located in the middle rotates, and relying on the first chain 36, all the first The sprockets 35 rotate synchronously in the same direction, so that the three first crankshafts 32 rotate synchronously, causing the storage box 4 to be subjected to a greater thrust, thereby preventing a single first crankshaft 32 from being unable to withstand the gravity of the top platform 34, resulting in damage to the components. When the first crankshaft 32 located in the middle rotates, it drives the second sprocket 372 located in the middle to rotate, and relies on the second chain 373 to drive the second crankshaft 371 to the east. The shape of the second crankshaft 371 is consistent with the shape of the first crankshaft 32, but the second crankshaft 371 and the first crankshaft 32 are symmetrical in terms of top and bottom. Therefore, when the second crankshaft 371 rotates, it drives the upper end of the second connecting rod 374 to move up and down, thereby driving the base plate 375 to move up and down. At the same time, the top platform 34 When the substrate 375 is shifted, it moves downward, and vice versa, the substrate 375 moves upward. The cutting head 377 is used to punch holes in the cardboard. The collecting tube 5 and the cutting head 377 move toward each other, which increases the cutting force of the cutting head 377. The first crankshaft 32 and the second crankshaft 371 are driven by the first motor 31 to rotate synchronously. The states of the two first crankshafts 32 and the second crankshaft 371 are mirrored, so that when the collecting tube 5 rises, the cutting head 377 descends, and vice versa, the cutting head 377 rises, so as to avoid the collecting tube 5 from affecting the movement of the placement rack 68 due to the lower surface of the cardboard being attached. At the same time, the collecting tube 5 and the cutting head 377 move toward each other, which increases the cutting force of the cutting head 377 and avoids the cut waste from sticking to the cardboard.
