[0023] Reference Figure 1~Figure 3, which is the first embodiment of the utility model, proposes a paper rejection device for rejecting unqualified paper, including a frame 1, a main conveyor belt 2, a visual recognition probe 3, a swing frame 4 and a rejection conveyor belt 5, the main conveyor belt 2 is rotatably arranged on the frame 1, and is used to convey paper, the visual recognition probe 3 is arranged on the frame 1, located above the main conveyor belt 2, and is used to take pictures to identify whether the paper is qualified, the swing frame 4 is swingably arranged on the frame 1, and the rejection conveyor belt 5 is rotatably arranged on the swing frame 4, the swing frame 4 and the rejection conveyor belt 5 are symmetrically provided with two, the two rejection conveyor belts 5 turn in opposite directions, and after the two swing frames 4 swing, the two rejection conveyor belts 5 clamp or cancel the clamping of the paper.

[0024] In this embodiment, the paper is transported on the main conveyor belt 2, and the visual recognition probe 3 above the main conveyor belt 2 takes a photo of the paper below to identify whether the paper is qualified. This visual recognition technology adopts the conventional visual recognition detection technology in the prior art, which will not be described in detail here. If the paper is qualified, the two swing frames 4 remain in an open state, and the paper continues to be transported backward normally. If unqualified paper is detected, an instruction is issued to the driving element that controls the swing of the swing frame 4 to control the upper and lower swing frames 4 to swing inward at the same time until both rejection conveyor belts 5 contact the paper. Because the upper and lower swing frames 4 are symmetrically arranged along the upper and lower sides of the paper, the two rejection conveyor belts 5 basically contact the paper at the same time. After clamping the paper, because the two rejection conveyor belts 5 turn in opposite directions, and the conveying direction of the rejection conveyor belt 5 is perpendicular to the conveying direction of the main conveyor belt 2, the paper will be transported to one side or the other, and the rejected paper can be collected in advance on that side. In this embodiment, the visual recognition probe 3 can automatically identify unqualified paper without manual judgment, and can quickly and automatically remove the paper. It is also arranged in the conveying system to achieve the effect of online removal of unqualified paper.

[0025] It also includes a baffle 6, which is arranged on the swing frame 4. After the swing frame 4 swings, the baffle 6 blocks or cancels the transportation path of the paper, so as to prevent the paper from being transported backward.

[0026] In this embodiment, in order to prevent the paper from passing over the swing frame 4 in advance and failing to be clamped when the paper is rejected, a baffle 6 is also provided on the swing frame 4. The baffle 6 can block the paper from continuing to be conveyed in advance, thereby ensuring that the rejection conveyor belt 5 can stably clamp the paper.

[0027] It also includes a gear 7 and a rack 8. The hinge points of the two swing frames 4 are coaxially provided with the gear 7. The rack 8 is slidably arranged on the frame 1. Both sides of the rack 8 have teeth, and the teeth on both sides are respectively engaged with the two gears 7.

[0028] In this embodiment, in order to drive the synchronous swing of the two swing frames 4, a gear 7 is coaxially arranged at the hinge point of the two swing frames 4, and a rack 8 is located between the two gears 7. Both sides of the rack 8 have teeth, and the teeth on both sides are respectively engaged with the two gears 7, so that the sliding of the rack 8 drives the two gears 7 to rotate simultaneously. The sliding of the rack 8 is driven by a cylinder installed on the frame 1.

[0029] It also includes a recovery bin 9, which is arranged on the frame 1 and located on one side of the swing frame 4. The recovery bin 9 has an opening at the top for collecting the rejected paper.

[0030] In this embodiment, in order to facilitate the collection of rejected paper, a recovery bin 9 is provided on one side of the frame 1. The upper end of the recovery bin 9 is open, and the opening is lower than the height of the paper. After being thrown out by the rejection conveyor belt 5, the paper can fall into the recovery bin 9, thereby realizing the automatic collection of the rejected paper. It is only necessary to clean the paper in the bin on time.

[0031] It also includes a pressing plate 10, which is slidably disposed in the recovery bin 9 and is used to press down the collected paper.

[0032] In this embodiment, in order to prevent paper from getting stuck in the top opening of the recovery bin 9 and blocking the entry of subsequent paper, a pressure plate 10 is slidably arranged in the recovery bin 9. The pressure plate 10 can slide vertically, and the paper can be pressed into the recovery bin 9 by sliding the pressure plate 10, thereby avoiding the problem of paper getting stuck in the top opening of the recovery bin 9 and ensuring that subsequent paper can enter normally.

[0033] It also includes a bottom plate 11, which is slidably arranged at the bottom of the recovery bin 9. The bottom plate 11 has two material receiving positions 12. After the bottom plate 11 slides, the two material receiving positions 12 alternately enter or leave the recovery bin 9.

[0034] In this embodiment, the bottom plate 11 at the bottom of the recycling bin 9 can slide horizontally, and after sliding, the two receiving positions 12 can alternately enter and exit the recycling bin 9. When it is necessary to clean the paper in the bin, the bottom plate 11 can slide horizontally to slide the receiving position 12 storing the paper out of the recycling bin 9, and then the paper can be transported. After the bottom plate 11 slides horizontally, the other receiving position 12 can enter the recycling bin 9 at the same time, ensuring that the recycling bin 9 can always collect and discard paper.

[0035] It also includes a guide plate 13, which is arranged on the frame 1. There are two guide plates 13, which are respectively located on both sides of the main conveyor belt 2. The end of the guide plate 13 has an inclined section 14 for guiding the paper.

[0036] In this embodiment, when the paper enters the main conveyor belt 2, if the paper itself is offset, the inclined section 14 at the end of the guide plate 13 can guide the paper and align its conveying direction. When the paper is conveyed on the main conveyor belt 2, it can always be guided by the guide plate 13 to ensure that the conveying direction is not offset.

[0037] The surface of the reject conveyor belt 5 has a rubber layer.

[0038] In this embodiment, a rubber layer is further provided on the surface of the rejecting conveyor belt 5 , and the rubber layer can increase the friction with the paper, thereby improving the conveying efficiency of the rejecting conveyor belt 5 for the paper and improving the rejecting efficiency.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
