Description

Technical Field

[0001] This utility model belongs to the technical field of weather resistance testing equipment, and in particular relates to a weather resistance testing device for modified plastics. Background Technology

[0002] Weather resistance refers to the ability of a material to maintain its performance, quality, and appearance when exposed to natural environments (including sunlight, high temperature, low temperature, rain, etc.) for a long period of time. Among these, the weather resistance parameter is most important for modified plastics. Conventional testing methods usually use a xenon lamp as a light source with a filter plate to obtain light of a specified wavelength, expose the material to the light, and then test the material. However, because the light irradiation of the material may be uneven, the test results will be biased, ultimately affecting the actual performance of the modified plastic.

[0003] Therefore, how to avoid uneven light irradiation of materials leading to deviations in test results is a technical problem that urgently needs to be solved in this field.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0039] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] See Figures 1-4 , Figure 1A weather resistance testing device for modified plastics is shown, comprising: a housing 1; a storage assembly 2 disposed at the bottom of the housing 1, the storage assembly 2 including a rotatably mounted base plate 21 and several storage racks 22, the storage racks 22 being mounted on top of the base plate 21, and the storage racks 22 having placement positions for placing the material to be tested; and a testing assembly 3 disposed at the top of the housing 1, the testing assembly 3 including a light source body 31, the light source body 31 being coaxially arranged with the axis of the base plate 21, so as to... The rotating axes of the rack 22 around the base plate 21 are arranged in an array, and the rack 22 and the light source body 31 are equally spaced. This modified plastic weather resistance testing equipment sets the axes of the light source body 31 and the base plate 21 coaxially, and sets the rack 22 around the base plate 21 in an array, so that the rack 22 and the light source body 31 are equally spaced. Rotating the base plate 21 allows the light from the light source body 31 to be evenly irradiated onto the material in the rack 22, ensuring the reliability of the test results.

[0041] In some embodiments, Figure 3 The shelf 22 is shown to include a "T"-shaped support body 22a and a shelf 22b mirror-mounted on the side wall of the support body 22a. The shelf 22b is tilted so that it faces the light source body 31. The shelf 22b is mirror-mounted on both sides of the support body 22a to ensure the stability of the shelf 22's center of gravity and prevent the shelf 22 from tipping over when the shelf base 21 rotates. Furthermore, the tilted shelf 22b ensures that the materials face the light source body 31, guaranteeing that the materials are evenly illuminated by light.

[0042] In some embodiments, Figure 3 The shelf 22b is shown to be fan-shaped, with a blocking strip 22c extending upward from the lower side and the side away from the support body 22a, so that a placement position is formed on the surface of the shelf 22b; wherein, the shelf base plate 21 is designed to be circular, and the shelf 22b is designed to be fan-shaped, so that the projection of the shelf 22b falls within the shelf base plate 21, avoiding interference between the shelf 22b and the box 1 when the shelf base plate 21 rotates, and the placement position can be formed on the surface of the shelf 22b by setting the blocking strip 22c.

[0043] In some embodiments, Figure 3The bracket body 22a is shown to include a pair of horizontal plates 22d and a pair of vertical plates 22e. The horizontal plates 22d are disposed at both ends of the vertical plates 22e to form a "T" shape. The storage plates 22b are respectively disposed on the side walls of the vertical plates 22e. A plurality of connecting holes 22f are provided on the lower horizontal plate 22d. The connecting holes 22f are connected to the storage base plate 21 by bolts. The bracket body 22a is formed by splicing the horizontal plates 22d and the vertical plates 22e, and the connecting holes 22f are provided on the lower horizontal plate 22d to complete the connection between the bracket body 22a and the storage base plate 21.

[0044] In some embodiments, Figure 4 The bottom plate 21 is shown to have a plurality of waist-shaped holes 21a arranged in an array along the axis of the bottom plate 21; wherein, the waist-shaped holes 21a on the bottom plate 21 can adjust the mirror position of the support body 22a and adjust the distance between the material and the light source body 31.

[0045] In some embodiments, Figure 4 The diagram shows that a connecting flange 21b is provided along the axis of the storage base plate 21. The side wall of the connecting flange 21b is provided with several insertion slots 21c. The bottom of the storage base plate 21 is provided with several reinforcing ribs 21d, and the ends of the reinforcing ribs 21d are engaged in the insertion slots 21c. The reinforcing ribs 21d can improve the rigidity of the storage base plate 21. At the same time, the connecting flange 21b is mainly responsible for transmitting torque to the storage base plate 21. The ends of the reinforcing ribs 21d are engaged in the insertion slots 21c, which can reduce the stress on the connection between the connecting flange 21b and the storage base plate 21 and improve the service life of the storage base plate 21.

[0046] In some embodiments, Figure 2 The enclosure 1 is divided into a test chamber 11, a storage chamber 12, and a drive chamber 13 by a layered structure. The test assembly 3 is disposed in the test chamber 11, and the light source body 31 is inserted into the storage chamber 12. A drive motor 4 is disposed in the drive chamber 13, and the output shaft of the drive motor 4 is inserted into the storage chamber 12. The storage base plate 21 is disposed in the storage chamber 12, and the storage base plate 21 is connected to the output shaft of the drive motor 4. The layered design of the enclosure 1 allows for better installation of the test assembly 3, the storage assembly 2, and the drive motor 4.

[0047] In some embodiments, Figure 4The diagram shows a drive base 41 disposed within the drive cavity 13, a reversing reducer 42 disposed within the drive base 41, a drive motor 4 mounted on the side wall of the reversing reducer 42, and the output shaft of the drive motor 4 connected to the input shaft of the reversing reducer 42. The output shaft of the reversing reducer 42 is inserted into the storage cavity 12 and connected to the storage base plate 21. In short, the reversing reducer 42 and the drive motor 4 are mounted on the drive base 41, and the drive base 41 is then installed into the housing 1, which improves the portability of the drive motor 4 installation.

[0048] In some embodiments, Figure 2 The enclosure 1 is divided into a test chamber 11, a storage chamber 12, and a drive chamber 13 by a shelf. The test chamber 11 contains several test components 3, and the light source body 31 is inserted into each independent chamber 12a. The drive chamber 13 contains several drive motors 4, and the output shafts of the drive motors 4 are inserted into the storage chambers 12. The storage chamber 12 is divided into several independent chambers 12a by a shelf, each independent chamber 12a containing a storage component 2, and each storage base plate 21 is connected to the output shaft of a drive motor 4. In short, by dividing the storage chamber 12 into several independent chambers 12a, multiple sets of tests can be performed on materials simultaneously using different light source bodies 31.

[0049] In some embodiments, Figure 1 The diagram shows that one end of the housing 1 is open, and a door panel 14 is hinged to the open end of the housing 1; in short, the door panel 14 allows the material to be tested in a nearly enclosed environment, reducing the interference of light.

[0050] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. 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.

[0051] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0052] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0053] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0054] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
