Description

Technical Field

[0001] The utility model relates to the technical field of paper conveying, in particular to a paper conveyor with a visual system. Background Art

[0002] In the current paper inspection process, because the paper is not effectively cleaned before inspection, the appearance inspection instrument will mistake good paper with dirt attached as defective when inspecting the appearance of the paper.

[0003] However, this situation results in a large number of papers that are actually of good quality being mistakenly rejected, resulting in inaccurate paper detection. In addition, the mistaken rejection of good quality papers also increases the subsequent remedial work and costs. Utility Model Content

[0004] The utility model aims at the technical problems existing in the prior art and provides a paper conveyor with a visual system to solve the problem that the appearance inspection instrument mistakenly identifies good paper with dirt attached as defective when inspecting the appearance of the paper due to the failure to effectively clean the paper before inspection.

[0005] The utility model solves the above technical problems with the following technical solutions: a paper conveyor with a visual system, comprising:

[0006] frame;

[0007] A conveying mechanism for conveying paper, wherein the conveying mechanism is arranged on the frame;

[0008] A cleaning component, the cleaning component is used to clean both sides of the conveyed paper, wherein the cleaning component includes a first carrier plate, a second carrier plate, a top surface cleaning assembly, and a bottom surface cleaning assembly, the first carrier plate is fixed to one side of the frame, the second carrier plate is fixed to one side of the first carrier plate, the bottom surface cleaning assembly is arranged on one side of the first carrier plate, and the top surface cleaning assembly is arranged on one side of the second carrier plate;

[0009] The appearance detection component is arranged on one side of the cleaning component and is used to detect the appearance of both sides of the paper.

[0010] The beneficial effects of the utility model are:

[0011] 1) The device uses the top and bottom cleaning components to clean both the top and bottom surfaces of the paper before testing, thereby removing dirt from the outside of the paper to be tested in advance. This prevents the appearance tester from mistaking good paper with dirt as defective, ensuring the accuracy of the appearance test component in testing the paper's appearance.

[0012] 2) In addition, the impurities and dirt on the paper surface can be reduced by cleaning the components, while improving the quality of the paper.

[0013] On the basis of the above technical solution, the present invention can also be improved as follows.

[0014] Furthermore, the first supporting plate and the second supporting plate are in an L shape.

[0015] Furthermore, the bottom surface cleaning assembly includes an air pipe and multiple blowing nozzles. The air pipe is fixed on a supporting plate and connected to an external air pump. The multiple blowing nozzles are connected to the air pipe in sequence along the axial direction of the air pipe, and the blowing opening of the blowing nozzle faces upward.

[0016] The beneficial effect of adopting the above further solution is that an external air pump provides air flow into the air pipe 1, and the air flow is ejected upward from the blowing opening of the blowing nozzle 1, which can blow the bottom surface of the paper and thus clean the dirt attached to the bottom surface of the paper.

[0017] Furthermore, the top surface cleaning assembly includes an air pipe 2 and multiple air blowing nozzles 2. The air pipe 2 is fixed on a supporting plate 2 and connected to an external air pump. The multiple air blowing nozzles 2 are connected to the air pipe 2 in sequence along the axial direction of the air pipe 2, and the blowing opening of the air blowing nozzle 2 faces downward.

[0018] The beneficial effect of adopting the above further solution is that an external air pump provides air flow into the air pipe 2, and the air flow is ejected downward from the blowing opening of the blowing nozzle 2, which can blow the top surface of the paper and thus clean the dirt attached to the top surface of the paper.

[0019] Furthermore, the appearance detection component includes CCD detector 1, CCD detector 2, a fixing plate, and a frame. The frame is fixed on one side of the frame, the fixing plate is arranged in the frame, the CCD detector 1 is located above the fixing plate and is arranged on the frame, and the CCD detector 2 is located below the fixing plate and is arranged on the frame.

[0020] Furthermore, the fixing plate is made of transparent glass.

[0021] The beneficial effect of adopting the above-mentioned further scheme is that when the paper of the conveying mechanism passes between the first air blowing nozzle and the second air blowing nozzle and falls onto the fixed plate, since the fixed plate is transparent glass, at this time, a pair of CCD detectors can capture the image of the top surface of the paper, thereby realizing the appearance detection of the top surface of the paper, and the second CCD detector captures the image of the bottom surface of the paper through the fixed plate, thereby realizing the appearance detection of the bottom surface of the paper. The use of a transparent glass fixed plate combined with the configuration of the above-mentioned two CCD detectors can effectively realize accurate appearance detection of the top and bottom surfaces of the paper, thereby improving the reliability and detection accuracy of the detection system.

[0022] Furthermore, one side of the frame is rotatably connected to a roller via a rotating shaft, and the roller is located above the first supporting plate.

[0023] The beneficial effect of adopting the above further solution is that the paper exiting the conveying mechanism is supported by the rollers, which effectively prevents the airflow sprayed toward the top surface of the paper by the second blowing nozzle from causing the paper to fall to the ground.

[0024] Furthermore, the air pipe is rotatably connected to a plurality of rollers via a rotating shaft.

[0025] The beneficial effect of adopting the above-mentioned further solution is that by arranging a roller made of silicone on the air pipe 1, the roller can be effectively used to block direct contact between the paper and the blowing nozzle 2, thereby preventing the paper from moving upward due to the airflow when the blowing nozzle 1 sprays air toward the bottom surface of the paper and possibly colliding with the blowing nozzle 2. This can effectively prevent the blowing nozzle 2 from penetrating the paper, thereby protecting the integrity and stability of the paper. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In the current paper inspection process, because the paper is not effectively cleaned before inspection, the appearance inspection instrument will mistake good paper with dirt attached as defective when inspecting the appearance of the paper.

[0034] However, this situation results in a large number of papers that are actually of good quality being mistakenly rejected, resulting in inaccurate paper detection. In addition, the mistaken rejection of good quality papers also increases the subsequent remedial work and cost. In response to this, the utility model proposed a paper conveyor with a visual system to solve the above problems.

Moreover, the air blowing opening of the air blowing nozzle 242 faces downward, and an air flow is provided into the air pipe 241 through an external air pump. The air flow is ejected downward from the air blowing opening of the air blowing nozzle 242, which can blow the top surface of the paper and thereby clean the dirt attached to the top surface of the paper.

[0045] In this embodiment, Figure 1-Figure 4As shown, the appearance detection component 300 includes a CCD detector 1 310, a CCD detector 2 320, a fixing plate 340, and a frame 330. The frame 330 is fixed to one side of the frame 100. The fixing plate 340 is arranged in the frame 330. The CCD detector 1 310 is located above the fixing plate 340 and is arranged on the frame 330.
