[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.
[0018] according to Figure 1-3 As shown, this embodiment proposes a thermal transfer carbon ribbon air tightness detection device, including a detection box 1, a thermal transfer carbon ribbon fixing mechanism 2 and a limiting roller 3. The interior of the detection box 1 is divided into a first pool area 4 and a second pool area 5 by a partition. The first pool area 4 contains detection liquid. A thermal transfer carbon ribbon fixing mechanism 2 is provided on the top of the detection box 1 at one end of the first pool area 4. A limiting roller 3 is symmetrically and rotatably provided inside the first pool area 4. A first bracket 6 and a second bracket 18 are provided on the top of the detection box 1 at the position of the second pool area 5. A first guide roller 7 is rotatably provided on the first bracket 6, and a second guide roller 8 is provided on the second bracket 18. A gas collecting chamber 9 is provided on one side of the upper end of the first bracket 6, and an air blowing pipe 10 is provided at the bottom of the gas collecting chamber 9. The air blowing pipe 10 is provided in multiple groups. An air inlet 11 is provided on the top of the gas collecting chamber 9, and the air inlet 11 is connected to an external air source.
[0019] When the thermal transfer carbon ribbon air tightness detection device of the present invention performs air tightness detection on the rolled thermal transfer carbon ribbon, the thermal transfer carbon ribbon roll is fixed by the thermal transfer carbon ribbon fixing mechanism 2, and then one end of the thermal transfer carbon ribbon is introduced under the two limiting rollers 3 inside the first pool area 4, so that the thermal transfer carbon ribbon is completely immersed in the detection liquid, and then one end of the thermal transfer carbon ribbon is continued to be introduced to the top of the first guide roller 7, and passed through the bottom of the second guide roller 8, and then one end of the thermal transfer carbon ribbon is connected to the traction and winding mechanism. If the thermal transfer carbon ribbon located inside the first pool area 4 and immersed in the detection liquid has holes and gaps, bubbles will overflow. Whether the air tightness of the thermal transfer carbon ribbon is good is detected by observing whether there are bubbles in the detection liquid. When the thermal transfer carbon ribbon pulled out from the first pool area 4 enters under the gas collecting chamber 9, the surface moisture will be removed by air blown out by the blowing pipe 10.
[0020] The thermal transfer ribbon fixing mechanism 2 includes a vertical plate 201, a guide post 202, a spring 203, and a positioning pin 204. The vertical plate 201 is symmetrically arranged on the top of the detection box 1 at one end of the first pool area 4. The guide post 202 is provided on the inner wall of the vertical plate 201, and a spring 203 is sleeved on the outer side of the guide post 202. One end of the spring 203 is connected to the vertical plate 201, and the other end of the spring 203 is provided with a positioning pin 204. When fixing the thermal transfer ribbon roll, the spring 203 is compressed, so that the positioning pin 204 is inserted into the holes at both ends of the thermal transfer ribbon roll to fix it.
[0021] The height of the first guide roller 7 is greater than that of the second guide roller 8. This setting allows water on the thermal transfer ribbon to automatically slide down and drip. The limiting roller 3, the first guide roller 7 and the second guide roller 8 are all rubber rollers.
[0022] A mounting bracket 12 is provided on the top of the detection box 1 in the first pool area 4, and a CCD camera 13 is provided on the top of the mounting bracket 12. The CCD camera 13 can record the process of detecting the thermal transfer carbon ribbon in the first pool area 4 to prevent errors in manual observation methods.
[0023] The top of the detection box 1 at the first pool area 4 is symmetrically provided with slide grooves 14, and the mounting bracket 12 is slidably connected to two sets of the slide grooves 14. The slide grooves 14 can be provided so that the installation position of the CCD camera 13 can be adjusted.
[0024] A top plate 15 is positioned above the two sets of vertical plates 201. A motorized telescopic rod 16 is mounted on the top plate 15. A mounting base is positioned below the top plate 15. Positioning rollers 17 are rotatably mounted within the mounting base. The output end of the motorized telescopic rod 16 is connected to the top of the mounting base. Positioning rollers 17 are provided to position the unwound thermal transfer ribbon.
[0025] The thermal transfer carbon ribbon air tightness detection device of the present invention can introduce the thermal transfer carbon ribbon into the first pool area 4 after installation, and use the liquid thermal transfer carbon ribbon inside to detect the air tightness, and the provided gas collecting chamber 9 and the blowing pipe 10 can blow away the residual liquid on the surface of the thermal transfer carbon ribbon after detection. The device of the present invention can realize all-round air tightness detection of the continuous thermal transfer carbon ribbon in a roll. The device structure is simple and easy to operate. The detection process can be photographed and recorded by the provided CCD camera 13 to ensure the accuracy of the detection result.
