Detailed ways

In order to fully understand the technical content of the present invention, the technical solutions of the present invention will be further introduced and illustrated below in conjunction with specific embodiments.

The specific structure of the embodiment of the present invention is shown in Fig. 1 to Fig. 7 .

The gray board box blank automatic forming device for packaging box processing in this embodiment includes a folding mechanism for cooperating with the mold cavity to fold the gray board into a box blank and a feeding mechanism for feeding the gray board to the folding mechanism.

The folding mechanism includes a base plate 11 , a movable plate 12 and a bearing assembly 20 . The bottom plate 11 is fixed on the ground, and the bottom of the bottom plate 11 is provided with a platform cylinder 33 for pushing the movable plate 12 to move vertically above the bottom plate 11. The output shaft of the platform cylinder 33 runs through the bottom plate 11 and is fixedly connected to the movable plate 12. The bearing assembly 20 is fixed above the movable plate 12 . The bearing assembly 20 includes a small bearing board 21 , a middle bearing board 22 and a large bearing board 23 arranged in sequence. The small surface carrying plate 21 and the middle carrying plate 22 are all fixed relative to the movable plate 12 during the gray plate folding process, so the small surface carrying plate 21 and the intermediate carrying plate 22 are all fixedly connected with the movable plate 12 through the vertical rod 16 . However, the large-surface carrying plate 23 will move vertically relative to the movable plate 12 during the gray plate folding process, so the large-surface carrying plate 23 needs to be installed on the movable plate through the fixed plate 13 . The fixed plate 13 is fixed on the movable plate 12 through the vertical plate 14, the fixed plate 13 is located between the large surface bearing plate 23 and the movable plate 12, and the guide rod 15 penetrating the fixed plate 13 is fixed below the large surface bearing plate 23, and the fixed plate 13 The vertical movement track of the large-surface bearing plate 23 is defined by the guide rod 15 .

A vertically movable small surface roller 41 is provided in the gap between the small surface carrying plate 21 and the middle carrying plate 22 , and the driving force is provided by the small surface cylinder 31 fixed on the movable plate 12 below the small surface roller 41 . Therefore facet roller 41 only moves vertically up and down, and is only responsible for folding one of the sides of the gray board box embryo.

The gap between the middle bearing plate 22 and the large surface bearing plate 23 is provided with a large surface roller 42, and the bottom of the large surface bearing plate 23 is provided with a large surface cylinder for promoting the large surface bearing plate 23 and the large surface roller 42 to move vertically at the same time 32. A horizontal air cylinder 34 for pushing the large surface roller 42 to move horizontally is provided under the large surface bearing plate 23. Therefore the big surface roller 42 can move vertically upwards earlier, and then move horizontally, which can be responsible for the folding of the other side and the top surface of the gray board box blank. The large surface cylinder 32 is located below the fixed plate 13, while the large surface cylinder 32 is fixed on the movable plate 12 and a reinforcing rib is arranged between the two. The output shaft of the large surface cylinder 32 runs through the fixed plate 13 and the output shaft is fixedly connected to the large surface bearing plate 23 through the U-shaped angle plate 17, and the horizontal cylinder 34 is fixed below the large surface load plate 23 and passes through the U-shaped angle plate 17 (see figure 3).

The carrying assembly 20 is used to place the gray boards to be folded, and the gray boards must be positioned before being folded. Therefore, the small surface bearing boards 21 and the large surface bearing boards 23 are all provided with retaining bars 24 for limiting the position of the gray boards. At the same time, before the folding action starts, it must be confirmed that the gray board has been placed on the carrying assembly 20, so the carrying assembly 20 is provided with a photoelectric detection switch 25 for detecting whether the gray board is in place. If the photoelectric detection switch 25 does not detect the gray plate, the folding process will not start. The photoelectric detection switch 25 can be respectively arranged on the small-surface bearing plate 21 , the middle bearing plate 22 and the large-surface bearing plate 23 .

The feeding mechanism includes a base plate 51 , a baffle assembly 60 for enclosing stacked gray boards, and a push plate 55 for pushing the gray boards out from below the shutter assembly 60 . The baffle assembly 60 is fixed on the base plate 51 . The fender assembly 60 includes a side fender 61 , a front fender 62 and a rear fender 63 , and the height of the front fender 62 relative to the base plate 51 is adjustable. When feeding, the pusher plate 55 pushes the gray plate out from the gap between the front baffle plate 62 and the base plate 51 .

See Fig. 1, Fig. 6 and Fig. 7, the height adjustment of the front baffle 62 is realized in the following way: the base plate 51 is provided with a square frame 58, there are two front baffles 62, and the front baffle 62 passes through the fixing blocks 65 respectively. Linked to each other with the horizontal bar 59 of the square frame 58 , the front baffle 62 can move up and down relative to the fixed block 65 , and the up and down movement of the front baffle 62 is realized by the threaded rod 66 .

The power source 52 of the pushing plate 55 is located below the base plate 51 (see FIG. 7 ), and the power source 52 is a servo motor. There are also two linear slide rails 56 and a cross bar 54 that can slide on the linear slide rails 56 below the base plate 51 . Pushing plate 55 has two, is located on cross bar 54 respectively. The base plate 51 is provided with two linear grooves 57 for the movement of the pushing plate 55 . When feeding, the power source 52 of the pusher plate 55 drives the cross bar 54 to slide along the linear slide rail 56 through the synchronous belt 53, thereby driving the pusher plate 55 to move in the linear groove 57, and the pusher plate 55 moves the single gray plate from The baffle assembly 60 pushes out and pushes the gray plate onto the carrying assembly 20 of the folding mechanism.

Specifically, the pushing plate 55 is pinned to the cross bar 54 and a torsion spring is arranged between the pushing plate 55 and the cross bar 54, and the force of the torsion spring makes the pushing plate 55 tilt upward and point to the feeding direction. When feeding, the front end of the pushing plate 55 is against the edge of the gray board and applies a thrust to it. And when the pusher plate 55 returned, the pusher plate 55 was returned through the gray plate below, and the front end of the pusher plate 55 was rotated downward by the gravity of the gray plate (torsion spring was twisted), until the front end of the pusher plate 55 broke away from the gray plate. When the plate is pressed, the front end of the pushing plate 55 is subjected to the active force of the torsion spring to rotate upwards and return to its original position.

In addition, the feeding mechanism also includes a pressing roller 64 for pressing the gray board, and the pressing roller 64 is arranged above the base plate 51 and in front of the front baffle plate 62 in the feeding direction of the gray board. When feeding, the gray board passes through the gap between the pressing roller 64 and the base plate 51 .

Gray board box blank feeding and folding forming process:

At the beginning, gray boards are stacked in the baffle assembly 60 , and the pusher plate 55 starts to move from the rear of the rear baffle 63 . The pushing plate 55 pushes the bottom gray board of the stacked gray boards, passes it through the gap between the front baffle plate 62 and the base plate 51 and the gap between the pressing roller 64 and the base board 51, and then reaches the bearing assembly 20 Go up, complete feeding, pusher plate 55 returns.

Whether the photoelectric detection switch 25 on the carrier assembly 20 detects the gray plate at all times, if the photoelectric detection switch 25 still does not detect the gray plate when the pusher plate 55 has gone through a feeding process, then it shows that the feeding process of the pusher plate 55 is Empty stroke, gray plate is not delivered, and pusher plate 55 needs to carry out a feeding process again.

If the photoelectric detection switch 25 detects that the gray plate is in place, the folding process can be started. The basic process of the folding process can refer to Figure 5. When folding the gray board, the gray board is placed on the bearing assembly 20 (the gray board can be covered with the small surface bearing plate 21, the middle bearing plate 22 and the large surface bearing plate 23). The middle carrier plate 22 is located right below the mold cavity 90 . The platform cylinder 33 stretches out, so that the movable plate 12 and the bearing assembly 20 move upwards (direction A in FIG. 5 ) simultaneously until the upper surface of the gray plate contacts the outer surface of the mold cavity 90 . Then the small face roller 41 moves upwards (direction B in Figure 5) to fold one side of the gray board, and the large face roller 42 moves upwards (direction C in Figure 5) to fold the other side of the gray board, and then the large face roller The drum 42 moves toward the facet roller 41 (direction D in FIG. 5 ) to fold the top surface of the gray board, and finally the gray board is folded into a square box blank. The outer wall of the mold cavity 90 is provided with a vacuum suction cup. During the folding process, the vacuum suction cup on the mold cavity 90 is opened all the way so that the gray board can fit the mold cavity 90 completely. After the folding is completed, the small surface roller 41 and the large surface roller 42 return to their original positions respectively, and finally the platform cylinder 33 retracts, but the vacuum suction cup of the cavity 90 needs to be opened continuously to bring the gray board box embryo to the next station superior.

The above statements only use examples to further illustrate the technical content of the present invention, so that readers can understand more easily, but it does not mean that the implementation of the present invention is limited to this, and any technical extension or re-creation done according to the present invention is subject to this protection of inventions.
