Detailed Implementation

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0028] Example 1

[0029] A device for inspecting the quality of printed graphics on pharmaceutical packaging boxes, such as Figure 1 , Figure 2 and Figure 7 As shown, the device includes a conveyor 1, conveyor partitions 12, a vision detector 2, a controller 3, baffles 4, a high-intensity lamp 5, a heating assembly 6, a pressing mechanism 7, and a scraping mechanism 8. Conveyor partitions 12 are evenly spaced along the conveyor belt of the conveyor 1. A vision detector 2 and a controller 3 are installed on the left side of the conveyor 1. Both the vision detector 2 and the conveyor 1 are electrically connected to the controller 3. Baffles 4 are connected to the front and rear sides of the top of the conveyor 1, respectively, located above the conveyor belt section of the conveyor 1, and are used to limit the movement of the medicine packaging box. A high-intensity lamp 5 is installed on the right side of the top of the conveyor 1. A heating assembly 6 is installed on the conveyor 1, which heats the medicine packaging box to test its heat resistance. The heating assembly 6 is equipped with a pressing mechanism 7 that presses the medicine packaging box firmly. The pressing mechanism 7 is equipped with a scraping mechanism 8 that scrapes the medicine packaging box to test its abrasion resistance.

[0030] like Figure 3 and Figure 4As shown, the heating component 6 includes a connecting frame 61, an air guide frame 62, heating pipes 63, and a fan 64. The connecting frame 61 is connected to the upper part of both the front and rear sides of the conveyor 1 by bolts. The air guide frame 62 is connected between the upper sides of the connecting frame 61 on both sides. The air guide frame 62 is located above the conveyor belt of the conveyor 1. Heating pipes 63 are evenly spaced at the top inside the air guide frame 62. The fan 64 is installed inside the air guide frame 62. The fan 64 is located below the heating pipes 63. When the fan 64 is started, it can blow the hot air heated by the heating pipes 63 downwards. The downward movement of the hot air can heat the medicine packaging box.

[0031] like Figures 5-9 As shown, the clamping mechanism 7 includes a belt conveyor group 71, conveyor partitions 72, connecting blocks 73, a clamping frame 74, a first pressing plate 75, and a first elastic element 76. Belt conveyor groups 71 are installed on both sides of the connecting frame 61. Multiple sets of conveyor partitions 72 are installed at intervals on the belt conveyor group 71. Each set of conveyor partitions 72 consists of two partitions, and the distance between two adjacent conveyor partitions 72 is the same as the distance between two adjacent conveyor partitions 12. Two connecting blocks 73 are connected to the belt conveyor group 71 between two conveyor partitions 72 in the same group. Do not approach the two conveyor partitions 72. The number of connecting blocks 73 on the two belt conveyor groups 71 is the same and their positions correspond one-to-one. A clamping frame 74 is slidably connected between the two corresponding connecting blocks 73. A first elastic element 76 is connected between the clamping frame 74 and the connecting block 73. A first pressing plate 75 is bolted to both connecting frames 61. The first pressing plate 75 is located on the moving trajectory of the clamping frame 74. When the clamping frame 74 moves, it will be squeezed by the first pressing plate 75 and move towards the conveyor 1. The movement of the clamping frame 74 can press down on the medicine packaging box to fix the medicine packaging box.

[0032] like Figures 7-9 As shown, the scraping mechanism 8 includes a scraping block 81, a second elastic element 82, and a squeezing assembly. The scraping block 81 is slidably connected to the clamping frame 74. The second elastic element 82 is connected between the scraping block 81 and the clamping frame 74. A squeezing assembly is provided between the scraping block 81 and the first squeezing plate 75. The squeezing assembly is used to squeeze the scraping block 81 to move along the clamping frame 74. The movement of the scraping block 81 can scrape the medicine packaging box.

[0033] like Figure 8 and Figure 9 As shown, the extrusion assembly includes a second extrusion plate 831 and a protrusion 830. The protrusion 830 is connected to the scraper block 81. The second extrusion plate 831 is bolted to the first extrusion plate 75. The second extrusion plate 831 is located at the moving trajectory of the protrusion 830. When the protrusion 830 moves, it will be extruded and moved by the second extrusion plate 831. The movement of the protrusion 830 can drive the scraper block 81 to move.

[0034] This device can be used when it is necessary to inspect the quality of medicine packaging boxes. In use, the unfolded medicine packaging box is placed on conveyor 1, and the boxes are separated by conveyor partition 12. Then, conveyor 1 is started to transport the medicine packaging box. When the medicine packaging box is transported to a position under a strong light 5, the strong light 5 can be activated to test the light-blocking properties of the medicine. After the test is completed, the medicine packaging box continues to be transported. Simultaneously, an external power source can be used to control the rotation of the belt conveyor group 71, ensuring that the belt conveyor group 71 and the conveyor 1 rotate at the same speed. The rotation of the belt conveyor group 71 drives the pressure frame 74 to rotate. When the pressure frame 74 rotates to contact the first compression plate 75, the pressure frame 74 continues to rotate and moves downwards through the first compression plate 75, compressing the first elastic element 76. After the clamping frame 74 moves downward, it can press down on the medicine packaging box to fix it. Since the belt conveyor group 71 and the conveyor 1 rotate at the same speed, the clamping frame 74 and the medicine packaging box also move at the same speed, so that the clamping frame 74 and the medicine packaging box are relatively stationary, ensuring stability during clamping. When the medicine packaging box moves to below the air guide frame 62, it can be heated by the heating pipe 63 and the hot air is blown downward by the fan 64 to the medicine packaging box to test the heat resistance of the printed graphics. Then the conveyor 1 continues to transport the medicine packaging box, and the clamping frame 74 will also continue to move with the scraping block 81. When the scraping block 81 moves, it will drive its upper protrusion 830 to move. When the protrusion 830 moves to contact the second extrusion plate 831, the protrusion 830 continues to move and is squeezed forward by the second extrusion plate 831 (e.g., Figure 9As shown, the forward movement of the protruding rod 830 causes the scraping block 81 to move forward, stretching the second elastic element 82. The forward movement of the scraping block 81 allows it to scrape the printed graphics on the medicine packaging box. As the protruding rod 830 continues to move, it disengages from the second extrusion plate 831. At this point, under the action of the second elastic element 82, the protruding rod 830 and the scraping block 81 move backward, thus scraping the medicine packaging box again to test the abrasion resistance of the medicine. The conveyor 1 continues to transport the medicine packaging box, and the belt conveyor group 71 continues to operate. With the operation of the belt conveyor group 71, the clamping frame 74 disengages from the first extrusion plate 75, and the clamping frame 74 also... Under the action of the first elastic element 76, the box is reset and detached from the medicine packaging box. When the conveyor 1 transports the medicine packaging box to the vision detector 2, the vision detector 2 can detect the medicine packaging box after light exposure, heating and scratching to determine whether the quality of the medicine packaging box after the above treatment is qualified. If it is unqualified, the vision detector 2 can send a signal to the controller 3, and the controller 3 controls the conveyor 1 to close, and then the unqualified medicine packaging box is taken out. If it is qualified, the conveyor 1 continues to operate to send out qualified medicine packaging boxes. In this way, the heat resistance, light protection and abrasion resistance of the printed graphics on the medicine packaging box can be detected, and the detection method is more diversified.

[0035] Example 2

[0036] Based on Example 1, such as Figure 1 and Figure 10 As shown, it also includes a pushing assembly 10, which includes an electric push rod 101 and a pushing plate 102. The electric push rod 101 is installed on the left side of the conveyor 1, and a notch is opened on the left side of the baffle 4. The pushing plate 102 is connected to the telescopic rod of the electric push rod 101. The pushing plate 102 can slide at the notch position of the baffle 4. The electric push rod 101 is electrically connected to the controller 3.

[0037] When the vision detector 2 detects that the medicine packaging box is unqualified, the vision detector 2 can send a signal to the controller 3. While controlling the conveyor 1 to shut down, the controller 3 can start the electric push rod 101 to drive the pusher plate 102 to move and push out the unqualified medicine packaging box. After being pushed out, the electric push rod 101 can control the pusher plate 102 to reset. In this way, there is no need to manually remove the medicine packaging box.

[0038] like Figure 1 and Figure 5As shown, it also includes a transmission assembly 11, which includes a first connecting plate 111, a second connecting plate 112 and a connecting rod 113. The first connecting plate 111 is connected to both the front and rear sides of the right drive shaft of the conveyor 1, and the second connecting plate 112 is connected to the right drive shaft of the two belt conveyor groups 71. The first connecting plate 111 and the second connecting plate 112 are the same size, and the connecting rod 113 is rotatably connected between the first connecting plate 111 and the second connecting plate 112.

[0039] When the conveyor 1 is in operation, it can drive the first connecting plate 111 to rotate. The rotation of the first connecting plate 111 can drive the second connecting plate 112 to rotate through the connecting rod 113. The rotation of the second connecting plate 112 can drive the belt conveyor group 71 to operate. Since the first connecting plate 111 and the second connecting plate 112 are the same size, the operating speed of the conveyor 1 and the belt conveyor group 71 are also the same. Thus, there is no need for an external power source to drive the belt conveyor group 71 to rotate, nor is there a need for manual control of the operating speed of the belt conveyor group 71, making operation more convenient.

[0040] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
