[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-5 In this embodiment, a detection device for high-temperature resistant thermal paper includes a protective bracket 1, two guide rollers 2 are rotatably installed at the rear end of the protective bracket 1, an adjustment mechanism is provided at the rear end of the protective bracket 1, a cleaning mechanism is provided inside the adjustment mechanism, and a detection mechanism is provided inside the protective bracket 1.
[0021] Among them, the setting of the two guide rollers 2 enables the triple-proof thermal paper to be effectively positioned and transported from the rear side.
[0022] In this embodiment, the cleaning mechanism includes a receiving bin 17, and there are two receiving bins 17. An electrostatic flannel roller 18 is rotatably installed inside the receiving bin 17. The front and rear electrostatic flannel rollers 18 pass through and extend to the opposite side of the receiving bin 17. A toothed scraper 19 with one end in contact with the electrostatic flannel roller 18 is fixedly installed on the inner top wall of the receiving bin 17. A collection box 20 is placed on the inner bottom wall of the receiving bin 17, and a protective door 21 is embedded on the opposite side of the receiving bin 17.
[0023] Among them, the provision of the protective door 21 allows the collection box 20 to be easily taken out for cleaning, and also allows the toothed scraper 19 and the electrostatic flannel roller 18 to be easily maintained.
[0024] Specifically, when the triple-proof thermal paper is transported downward and moves toward the front side, after contacting the electrostatic velvet roller 18, due to the friction factor, the left and right electrostatic velvet rollers 18 are driven to rotate relative to each other, so that the dust on the surface of the triple-proof thermal paper is electrostatically adhered and the dust is brought into the interior of the holding bin 17. When the electrostatic velvet roller 18 is combed by the toothed scraper 19, the dust on its surface is brushed off and falls into the collection box 20 for collection due to gravity.
[0025] In this embodiment, the detection mechanism includes a driving roller 3, a reduction motor 4, a U-shaped frame 6, an adjusting cylinder 8, a camera 9 and a lighting lamp 10. The driving roller 3 is rotatably installed at the inner front end of the protective bracket 1, the U-shaped frame 6 is rotatably installed at the inner front end of the protective bracket 1, and a positioning roller 7 is rotatably installed inside the U-shaped frame 6. The interior of the protective bracket 1 is fixedly installed with a reduction motor 4, and the output end of the reduction motor 4 is provided with a transmission assembly 5 with one end arranged on the outside of the driving roller 3. The left and right ends of the interior of the protective bracket 1 are hinged with an adjusting cylinder 8 with one end hinged to the U-shaped frame 6. The camera 9 is fixedly installed on the inner top wall of the protective bracket 1, the lighting lamp 10 is fixedly installed inside the protective bracket 1, and a coaxial lamp 22 is fixedly installed on the outside of the camera 9. The camera 9 is located between the driving roller 3 and the guide roller 2, the lighting lamp 10 is located below the camera 9, the driving roller 3 is located in front of the lighting lamp 10, and the positioning roller 7 is in contact with the driving roller 3.
[0026] Among them, the transmission component 5 includes two sprockets and a chain. The two sprockets are fixedly installed on the output end of the reduction motor 4 and the outside of the driving roller 3, so that the two are transmitted through the chain to realize the driving roller 3 to drive the triple-proof thermal paper for transportation.
[0027] Specifically, the reduction motor 4 is started to drive the driving roller 3 to rotate through the transmission component 5, so that the triple-proof thermal paper moves forward through the upper and lower guide rollers 2. At this time, the lighting lamp 10 and the coaxial lamp 22 illuminate the triple-proof thermal paper. The lighting lamp 10 allows the light from below to pass through the triple-proof thermal paper to enhance the contrast of the image, making its internal black spots and holes more prominent. The coaxial lamp 22 allows the light to irradiate parallel and vertically to reduce interference factors in the image.
[0028] It should be noted that when the triple-proof thermal paper is installed on the outside of the driving roller 3, the adjusting cylinder 8 can be started to drive the U-shaped frame 6 to rotate backward with the rotating installation point of the protective bracket 1 as the center point, so that the triple-proof thermal paper of different thicknesses contacts the driving roller 3 and the positioning roller 7, and is effectively positioned and transported.
[0029] In this embodiment, the adjustment mechanism includes a fixing frame 11, and there are two fixing frames 11. The fixing frames 11 are respectively fixedly installed on the left and right ends of the interior of the protective bracket 1. A U-shaped load-bearing frame 12 is fixedly installed on the top of the fixing frame 11, and two positioning rails 13 are fixedly installed on the opposite side of the inner wall of the U-shaped load-bearing frame 12. A bidirectional screw 14 with one end passing through and extending to the back of the U-shaped load-bearing frame 12 is rotatably installed inside the U-shaped load-bearing frame 12, and a screw head 16 is fixedly installed on the back of the bidirectional screw 14. The front and rear ends of the outside of the bidirectional screw 14 are threadedly installed with a movable block 15 with one end slidingly installed on the outside of the positioning rail 13. The front and rear accommodating chambers 17 are respectively fixedly installed between the front and rear movable blocks 15, and the lower guide roller 2 is located below the accommodating chamber 17, and the upper guide roller 2 is located above the accommodating chamber 17.
[0030] Specifically, when testing triple-proof thermal paper of different thicknesses, the screw head 16 is rotated to make the front and rear movable blocks 15 move relative to or opposite to each other outside the bidirectional screw 14, and the positioning track 13 is used to limit the position, so as to realize the relative or opposite movement of the electrostatic flannel roller 18 in the cleaning mechanism, making the use more flexible.
