[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0015] like Figure 1-2As shown, a label paper weathering resistance testing device includes a support frame 1, a cover 2 mounted on the support frame 1, an ultraviolet light generating module 3 mounted on the inner top surface of the cover 2, an environmental control module 4 mounted on the outer surface of the cover 2, a first placement plate 5 slidably connected to the support frame 1, a handle 6 mounted on one side of the first placement plate 5, a baffle 7 mounted on one side of the cover 2 and slidably connected to the cover 2, a fixed plate 8 mounted on one side of the cover 2, a movable plate 9 mounted on one side of the baffle 7, a screw 10 rotatably connected to the fixed plate 8, a rocker arm 11 mounted on the upper end of the screw 10, and the screw 10 and the movable plate 9... The support frame 1 is threaded and has a placement groove on one side. A pull-out cabinet 12 is slidably connected inside the placement groove. A partition 13 is provided on the pull-out cabinet 12. A heat insulation layer 14 is provided on one side of the partition 13. A second placement plate 15 and a third placement plate 16 are respectively provided on the pull-out cabinet 12 and on both sides of the partition 13. A number of bosses 17 are provided on the first placement plate 5, the second placement plate 15 and the third placement plate 16. A through groove is provided on one side of the upper surface of the support frame 1. A vertical plate 18 is provided on the upper surface of the support frame 1 and on one side of the through groove. Through holes 19 are evenly provided on the other side of the upper surface of the support frame 1.

[0016] The UV light generating module 3 preferentially uses UVB-313 lamp tubes, which can quickly screen the weather resistance of label paper and shorten the testing time.

[0017] The environmental control module 4 includes a heating system that uses a resistance wire or a heating element to heat the heating device and adjusts the heating power through a temperature control device. It is also equipped with a temperature sensor, such as a thermocouple or a PTC sensor, to monitor the temperature inside the housing 2 in real time and feed it back to the temperature control device, such as a PID controller, to automatically adjust the power of the heating equipment to maintain a constant temperature. The set target temperature is, for example, 50°C.

[0018] The environmental control module 4 also includes a humidity generator, such as a humidifier, which increases the humidity inside the housing 2 by evaporating water. It is also equipped with a dehumidifier to reduce the humidity inside the housing 2. In addition, it is equipped with a humidity sensor, such as a capacitive or resistive humidity sensor, to monitor the humidity inside the housing 2 in real time. The humidity sensor collects the actual humidity value and feeds it back to the humidity control system. The controller adjusts the humidification or dehumidification according to the deviation. When the humidity needs to be increased, the humidifier is started. When the humidity needs to be reduced, the dehumidifier is started. The temperature control device and the humidity controller are linked and adjusted through a PID algorithm to ensure the stability of temperature and humidity.

[0019] When testing the weather resistance of the label paper, firstly, the first placement plate 5 is pulled out from the housing 2 using handle 6. Then, multiple labels are sequentially attached to different protrusions 17. Next, the first placement plate 5 is pushed back into the housing 2. Then, the screw 10 is rotated by the rocker arm 11. Through the threaded connection between the screw 10 and the movable plate 9, the movable plate 9 and the baffle 7 move downwards. When the lower surface of the baffle 7 contacts the upper surface of the first placement plate 5, the rotation of the screw 10 is stopped. At this point, all the labels on the first placement plate 5 are within the test space enclosed by the support frame 1, the housing 2, and the baffle 7. Then, pull out the drawer cabinet 12 from the support frame 1, and attach the labels of the same batch to the protrusions 17 on the second placement plate 15 and the third placement plate 16 respectively. Then, push the drawer cabinet 12 back into the support frame 1. At this time, a test space is formed between the drawer cabinet 12, the partition 13 and the support frame 1. This control space is connected to the space of the first placement plate 5. The temperature and humidity in the space where the first placement plate 5 and the second placement plate 15 are located can be adjusted simultaneously through the environmental control module 4. However, due to the presence of the upright plate 18, the ultraviolet light generating module 3 can only act on the label paper on the first placement plate 5.

[0020] The space where the third placement plate 16 is located can exchange air normally with the outside through the through hole 19. At the same time, during the test, the entire device is located in a qualified laboratory to avoid the impact of unsuitable external conditions such as temperature, humidity, and light on the weather resistance test of the label paper.

[0021] Due to the variety of materials used in label paper, and the presence or absence of coatings or films, appropriate testing conditions and standards need to be selected based on specific circumstances to improve the validity of the results.

[0022] Furthermore, two positioning rods 20 are provided on the lower surface of the baffle 7. Positioning grooves for the positioning rods 20 to pass through are provided on the first placement plate 5 and the partition plate 13. After the labels are placed on the first placement plate 5, the second placement plate 15, and the third placement plate 16, the pull-out cabinet 12 is first pushed into the support frame 1, and then the first placement plate 5 is pushed into the cover 2. Then the rocker arm 11 is turned, which drives the screw 10 to rotate. As the baffle 7 moves downward, the positioning rods 20 at the lower end of the baffle 7 will first... Passing through the first placement plate 5 and entering the positioning groove on the partition 13, the pull-out cabinet 12 cannot be freely pulled out from the support frame 1 at this time, so that the first placement plate 5, the second placement plate 15 and the third placement plate 16 are all in a relatively stable space. Only after the label paper on the first placement plate 5 has completed the test can the label paper on the second placement plate 15 and the third placement plate 16 be taken out, ensuring that the label paper on the three placement plates is tested for approximately the same time, and avoiding instability of test results caused by the movement of the pull-out cabinet 12.

[0023] Furthermore, a stop 21 is provided at the lower end of the screw 10 to prevent the screw 10 from separating from the movable plate 9.

[0024] Furthermore, a reinforcing sleeve 22 is provided on the lower surface of the movable plate 9. The reinforcing sleeve 22 is threadedly connected to the screw 10 to improve the stability of the fit between the screw 10 and the movable plate 9.

[0025] Furthermore, the rocker arm 11 is slidably connected to the screw 10.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
