[0002] When the electrothermal constant temperature forced air drying oven is used for the thermal aging test of TPV materials, the drying oven needs to be opened multiple times to take out the test samples to observe the drying condition of the samples. Frequent opening of the drying oven will cause the temperature of the drying oven to drop rapidly, resulting in large temperature fluctuations in the drying oven, which will lead to unstable data and thus affect the accuracy of the thermal aging experiment.

Detailed Embodiment

[0019] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation of the present utility model.

[0020] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above and to the right", and "on the upper surface" of the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below and to the left", and "on the lower surface" of the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0022] As Figures 1 to 2 shown, a thermostatic forced-air drying oven 10 of the present application includes: a box body 11, and the box body 11 is formed with a take-out window 111 for taking out the dried samples undergoing heat aging experiments. A baffle for closing the take-out window 111 is provided at the take-out window 111. In this way, when it is necessary to take out the sample, the baffle can be opened, and there is no need to open the whole drying oven, which avoids the rapid loss of the temperature inside the drying oven, thus avoiding large temperature fluctuations inside the drying oven, and ensuring the continuous stability of the subsequent heat aging experiment.

[0023] As a specific implementation structure of this solution, a platform 13 for placing samples is further provided inside the box body 11. A lifting cylinder 14 for lifting the platform 13 is provided below the platform 13. In this way, the sample undergoing the experiment can be lifted to the take-out window 111 through the lifting cylinder 14, facilitating the user to take it out for observation. When continuing the heat aging experiment, the sample is lowered to the lower side inside the box body 11 through the lifting cylinder 14. Since there is a certain distance between the lower side inside the box body 11 and the upper take-out window 111, the temperature loss during taking out the sample is relatively low and the temperature stability is high, which can ensure the accuracy of the experiment.

[0024] Furthermore, a moving track 15 is formed on the platform 13. A slider 16 is slidably mounted on the moving track 15, so that the slider 16 can slide to support and drive the sample being dried to move. An ejecting cylinder 19 is installed on the upper side of the platform 13 to drive the slider 16 to move, so as to drive the sample to the window, facilitating the staff to quickly take out the specimen for observation and reducing the temperature loss ratio in the drying oven. During installation, the slider 16 is connected to the end of the cylinder rod of the ejecting cylinder 19. Specifically, a pushing block can be provided below the slider 16 and fixed to the end of the cylinder rod of the ejecting cylinder 19. In this way, when the lifting cylinder 14 lifts the specimen to the height of the taking-out window 111, the ejecting cylinder 19 transports the specimen to the taking-out window 111 on the side of the box body 11, and the staff can take the specimen, with higher taking-out efficiency.

[0025] Based on the above improvements to the structure of the electrothermal constant temperature forced-air drying oven 10, taking out the specimen is not only convenient but also can avoid large fluctuations in the temperature inside the drying oven, effectively solving the problem that when the electrothermal constant temperature forced-air drying oven 10 is used in the TPV material thermal aging test, the drying oven needs to be opened multiple times to take out the specimen for observation, resulting in large temperature fluctuations in the drying oven, and further ensuring the stability of the thermal aging test data and making the experiment more accurate.

[0026] As a specific implementation manner, a limiting edge 18 is formed on the periphery of the slider 16. The drying sample's placement position can be limited by the limiting edge 18. An opening 181 is formed on the side of the limiting edge 18 facing the window for inserting and placing the dried sample. Placing the sample is not only convenient but also very stable, ensuring that the position of the specimen is almost unchanged after being taken out and put back multiple times, and the constant temperature air-drying degree is stable.

[0027] Furthermore, sliding rings 182 are formed at the lower ends on both sides of the limiting edge 18. Horizontal guiding columns 17 are provided on both sides of the slider 16. The limiting edge 18 is slidably sleeved on the corresponding horizontal guiding columns 17 through the sliding rings 182, so that it can be slidably mounted above the slider 16 in the horizontal direction. In this way, when taking out the specimen, by pulling the limiting edge 18 horizontally towards the taking-out window 111, the specimen can be quickly moved to the taking-out window 111, improving the taking-out efficiency.

[0028] Specifically, a pull rod 183 is formed on the side of the limiting edge 18 facing the taking-out window 111. The pull rod 183 is used to extend out of the window when the slider 16 moves to a preset position. At this time, the staff can directly pull the pull rod 183 to directly push the specimen to the taking-out window 111 through the limiting edge 18.

[0029] As a specific implementation, a chute 1111 is formed on the side wall of the extraction window 111, and the baffle is a drawer plate 12 slidably arranged in the chute 1111. The extraction window 111 is closed or opened by the drawer plate 12. By adopting such a sliding and pulling opening method, the size of the opened extraction window 111 can be adjusted according to the actual situation, so as to control the temperature loss in the box body 11.

[0030] As a specific implementation, the drawer plate 12 is made of a transparent material, which is convenient for the staff to observe the internal constant temperature air-drying situation.

[0031] As a specific implementation, the end of the drawer plate 12 extends out of the window to the upper side of the box body 11, which is convenient for the staff to pull the above-mentioned drawer plate 12, and the operation is more convenient.

[0032] As a specific implementation, the platform 13 is a hollow structure, and the slider 16 is also a hollow structure, which can ensure the balance of the all-round constant temperature air-drying of the specimen, and the experiment is more accurate. Moreover, the slider 16 is made of a heat-resistant ceramic material, so as to reduce the influence of the heat absorption of the slider 16 itself on the specimen, and avoid the bottom side of the specimen being baked at a high temperature due to the excessive heat absorption of the slider 16 itself, thereby further ensuring the balance of the all-round constant temperature air-drying of the specimen.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by using equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
