And on the surface of the front support rod 53, a moving column 56 is connected through an elastic component 55. And a control groove 57 for controlling the moving column 56 is opened on the inner surface of the central cylinder 54.

[0026] Please refer toFigures 11-12 , in the embodiment of the present invention, the elastic component 55 includes: The connecting column 551 is installed on the arc surface of the front support rod 53, and a placing groove 552 is formed on the opposite side of the connecting column 551 and the moving column 56; The pushing spring 553 has two ends respectively fixed to the opposite sides of the placing groove 552 and the moving column 56, and the pushing spring 553 resets elastically without external force to move the moving column 56 outward from the placing groove 552.

[0028] Please refer to Figures 7-9 , in the embodiment of the present invention, the clamping unit 6 includes: The clamping plates 61 are symmetrically arranged in two. Fixed rings 62 are installed on the opposite sides of the two clamping plates 61. After the fixed rings 62 come into contact with the side surface of the light source lamp 42, the light source generation operation of the light source lamp 42 is realized. A moving block 63 is installed on the top of the clamping plate 61, and the side surface of the rear clamping plate 61 is fixed to the surface of the central cylinder 54 through an insulating connecting plate 64; The clamping box 65 is installed inside the detection box 51, and the movement of the rear moving block 63 is realized through a pneumatic component 66 inside the clamping box 65. The rear moving block 63 extends through the clamping box 65 and the relative or opposite movement of the front moving block 63 is realized through a linkage component 67.

[0029] By setting the clamping unit 6, the locking cylinder 661 drives the piston rod 662 to move, which drives the movement of the rear moving block 63. The movement of the rear moving block 63 drives the rotating rod 672 to rotate around the rotating shaft 671 through the linkage rod 673, and then another linkage rod 673 rotates. Then, the two moving blocks 63 move away from or towards each other, realizing the clamping or opening of the clamping plate 61, so as to realize the stable clamping of the light source lamp 42, form a circuit closed-loop at the same time, and realize the switching of the light source lamp 42 by relying on the movement of the clamping plate 61 to open and close, effectively ensuring the stability and diversity of the detection operation.

[0030] The fixing of the fixing ring 62 and the clamping plate 61 can be electrically connected to an external power source through a wire, and the opening and closing control can be realized through a switch. At the same time, the fixing ring 62 contacts the two sides of the light source lamp 42 to realize a closed-loop operation, so as to realize the operation of the light source lamp 42 generating light, and this operation is an existing mature technology.

[0031] Please refer to Figure 9 In the embodiment of the present invention, the pneumatic component 66 includes a locking cylinder 661 fixedly installed inside the clamping box 65, and a piston rod 662 is slidably arranged inside the locking cylinder 661, and one end of the piston rod 662 is fixed to the side surface of the rear moving block 63.

[0032] Among them, the locking cylinder 661 is a lockable cylinder, so as to realize the fixing operation of the moved position for better detection. And the locking cylinder 661 can be communicated with an external air circuit, and the opening and closing operation can be realized through a personnel control panel, which is an existing mature technology.

[0033] Please refer to Figure 8 In the embodiment of the present invention, the linkage component 67 includes: A rotating shaft 671, rotatably installed at the center of the bottom of the inner cavity of the clamping box 65, and a rotating rod 672 is installed at the top of the rotating shaft 671; A pair of linkage rods 673 are arranged in parallel, the relative ends are respectively rotatably connected to the two ends of the rotating rod 672, and the mutually separated ends are rotatably connected to the tops of the moving blocks 63, realizing the synchronous movement of the two moving blocks 63 away from or towards each other.

[0034] Please refer to Figures 2-4 In the embodiment of the present invention, the adjusting part 8 includes: A trough-shaped frame 81, installed on the inner wall of the detection cabinet 3 and with an upper opening; The I-shaped block 82 is provided with a pair that fits into the trough-shaped frame 81 and slides horizontally inside the trough-shaped frame 81. Between the eaves on the front side of the I-shaped block 82, bumps 83 are installed, and the front ends of the two bumps 83 are respectively connected and fixed to the rear side of the detection unit 7 and the detection box 51. Inside the trough-shaped frame 81 and between the two I-shaped blocks 82, a traction assembly 84 is provided to realize the relative or opposite movement of the I-shaped block 82.

[0035] Please refer to Figures 4-5 , in the embodiment of the present invention, the traction assembly 84 includes: A driving motor 841 is installed on the platform at the center of the top of the trough-shaped frame 81. One end of the output shaft of the driving motor 841 is fixed with a driving shaft 842 through a coupling. One end of the driving shaft 842 penetrates and extends to the bottom of the platform and is fixed with a driving gear 843; There are a pair of transmission racks 844, which are arranged in the front and rear directions of the driving gear 843. The mutually remote ends of the two transmission racks 844 are respectively fixed to the opposite sides of the I-shaped block 82, and the driving gear 843 meshes with the surface of the transmission rack 844 to realize the movement of the transmission rack 844 when the driving gear 843 rotates.

[0036] By providing the adjustment part 8, the driving motor 841 drives the rotation of the driving shaft 842, and then the driving shaft 842 drives the rotation of the driving gear 843. Due to the meshing of the transmission rack 844 and the driving gear 843, the movement of the transmission rack 844 is realized. At this time, the two I-shaped blocks 82 are driven to move synchronously relatively or oppositely, and then the movement of the detection unit 7 and the detection box 51 is realized, thereby changing the position of the light source generated and the position of the received reflected light, so as to complete the multi-angle adjustment of color detection in the detection operation, ensuring more complete product detection and more accurate data results.

[0037] The driving motor 841 is electrically connected to an external power supply and can be controlled to be turned on and off through a control panel. At the same time, the driving motor 841 is a reduction motor, which can realize forward and reverse operations and has a self-locking function to fix the rotation position.

[0038] Among them, when the driving gear 843 rotates to realize the relative movement of the transmission rack 844, the angle between the light source and the reflected light during detection becomes smaller at this time. On the contrary, when the driving gear 843 rotates to realize the opposite movement of the transmission rack 844, the angle between the light source and the reflected light during detection becomes larger at this time, so as to realize the regulation of the light source conditions at different angles. The rotation teeth of the driving gear 843 and the distance moved by the transmission rack 844 change the angle of the light source, and the specific calculation method is not elaborated in detail and is controlled by its own existing control system.

[0039] Embodiment 2. The difference compared with Embodiment 1 is that the present invention also discloses an automatic detection method for the color of printed matter, which specifically includes the following steps: S1. The transmission component 2 is used to transmit the printed matter into the interior of the detection cabinet 3 and stay during detection. S2. The light source unit 4 generates a light source to irradiate the printed matter, and the detection unit 7 receives and analyzes the reflected light. At the same time, the switching unit 5 is used to switch the light source to simulate tests in different environments, and the adjustment unit 8 is used to adjust the positions of the light source unit 4 and the detection unit 7 to change the light source angle during detection. S3. The detected data is displayed through a visualization interface.

[0040] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0041] During operation, the product is placed on the transmission component 2, and the existing transmission component 2 is relied on to transmit the printed matter into the interior of the detection cabinet 3 and stay during detection. Then, the light source of the light source lamp 42 is used to irradiate the printed matter at the initial angle, and the detection unit 7 receives and analyzes the reflected light. After completion, the angle of the light source lamp 42 is adjusted. By generating an instruction and transmitting it to the drive motor 841, the drive motor 841 drives the rotation of the drive shaft 842. Then, the drive shaft 842 drives the drive gear 843 to rotate. Due to the meshing of the transmission rack 844 and the drive gear 843, the transmission rack 844 moves. At this time, the two I-shaped blocks 82 move synchronously in opposite or away directions. Then, the I-shaped blocks 82 drive the bumps 83 to move, and then the detection unit 7 and the detection box 51 move, thereby changing the position where the light source is generated and the position where the emitted light is received. After the detection operation with the angle change is completed, the initial angle is reset. At this time, different scenarios are simulated by switching the light source. By generating a corresponding instruction and transmitting it to the lock cylinder 661, the lock cylinder 661 drives the piston rod 662 to move, and drives the movement of the rear moving block 63. Then, the movement of the rear moving block 63 drives the rotating rod 672 to rotate around the rotating shaft 671 through the linkage rod 673, and another linkage rod 673 rotates, and then the two moving blocks 63 move away from each other. At this time, the two clamping plates 61 also open and separate from the light source lamp 42. During the process of the clamping plate 61 moving and opening, at this time, the connecting plate 64 drives the central cylinder 54 to move synchronously, and the control groove 57 in the central cylinder 54 drives the moving column 56 to contract. At this time, the curved surface groove in the control groove 57 controls the moving column 56, so that the moving column 56, the connecting column 551 and the support rod 53 rotate during the moving process, and rotate around the center of the support rod 53, thereby driving the rotation of the fixing plate 41, so as to realize the switching operation of different light source lamps 42; And after the switching is completed, the locking cylinder 661 drives the piston rod 662 to move, so that the two clamping plates 61 move relatively. And at this time, during the moving process, the connecting plate 64 drives the central cylinder 54 to move synchronously, and the control groove 57 in the central cylinder 54 drives the moving column 56 to contract. At this time, the straight groove in the control groove 57 abuts against the moving column 56, so that the moving column 56 contracts, but does not rotate. Then, after the fixing rings 62 opposite to the clamping plates 61 contact the side surface of the light source lamp 42, the light source generation operation of the light source lamp 42 is realized; Finally, the detected data is displayed through the visualization interface installed on the side of the detection cabinet 3.
