Description

Technical Field

[0001] This utility model relates to the field of testing technology for prepregs of polymer composite materials, and more specifically, to an auxiliary device for testing the volatile content of prepregs. Background Technology

[0002] As is well known, prepregs play a crucial role in the preparation of composite products, possessing high added value, and their quality has a decisive impact on the performance of composite products. Volatile content is one of the most important evaluation indicators for the consistency of prepreg quality. The gravimetric method has been a long-used testing method with clearly defined procedures and testing parameters in the standards, resulting in accurate test results. However, the lightweight support used in the test needs to be quickly removed from the drying oven, and the sample needs to be quickly removed from the support. At this time, the temperature of both the support and the sample is above 100℃. Due to the limited space in the drying oven, the size of the support is somewhat restricted. Therefore, the test personnel can easily be burned if they are not careful, and safety cannot be guaranteed. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an auxiliary device for testing the volatile matter of prepregs, which can prevent testers from being burned by the adjacent column when handling samples.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an auxiliary device for testing the volatile matter of prepreg, which is equipped with a frame. The frame is characterized in that it is a cuboid structure composed of a bottom frame, columns, a top frame and a limiting ring. The bottom frame and the top frame are both rectangular hollow structures. A column is fixed at each of the four corners of the bottom frame, and the upper ends of the four columns are vertically fixed on the top frame. A carrying frame is hinged to one side of the frame opening. The carrying frame is a rectangular hollow structure composed of a crossbar, a support rod and a rotating ring. The end of the crossbar can be inserted into the end of the top frame via the limiting ring. The rotating ring is hinged to the bottom frame of the frame. A limiting frame is fixed to both sides of the frame on one side of the carrying frame. The limiting frame is composed of a retaining ring, a baffle and a limiting pin. One end of the retaining ring is fixed to the column, and the other end of the retaining ring is an arc-shaped locking opening. Baffles are installed at both ends of the arc-shaped locking opening via the limiting pin.

[0005] The rotating ring has high-temperature resistant rubber rings installed on both sides.

[0006] The crossbar has multiple non-connected recesses.

[0007] The beneficial effects of this invention are that by using this device to test the volatile matter content of prepregs, it is possible to avoid the test personnel being burned by the adjacent column when handling the sample. Moreover, the device has a simple structure, is easy to operate, and does not require high skill from the test personnel. Attached Figure Description

[0015] As shown in the figure, this utility model consists of three parts: a frame 1, a shelf 2, and a limiting frame 3. The frame 1 is a cuboid structure composed of a bottom frame 1-1, uprights 1-2, a top frame 1-3, and a limiting ring 1-4. Both the bottom frame 1-1 and the top frame 1-3 are rectangular hollow structures. An upright 1-2 is fixed to each of the four corners of the bottom frame 1-1, and the upper ends of the four uprights 1-2 are vertically fixed to the top frame 1-3. The shelf 2 is hinged to an opening on one side of the frame 1. The shelf 2 consists of a crossbar 2-1 and a support rod. The crossbar 2-2 and rotating ring 2-3 form a rectangular hollow structure. Multiple unconnected recesses are provided on the crossbar 2-1. The end of the crossbar 2-1 can be inserted into the end of the top frame 1-3 via a limiting ring 1-4. The limiting ring 1-4 on the frame 1 controls the position of the shelf 2. When the limiting ring 1-4 moves outward, it is in an open state, allowing the shelf 2 to rotate. When it moves inward, it is in a locked state, locking the shelf 2. The shelf 2 can rotate around the horizontal axis of the bottom frame 1-1. The rotating ring 2-3 is hinged to the bottom frame 1-1 of the frame 1. High-temperature resistant rubber rings are installed on both sides of the rotating ring 2-3, ensuring that the shelf 2 can only rotate around the bottom frame 1-1 and cannot move axially. The limiting frame 3 is fixed on both sides of the frame 1 on one side of the shelf 2. The limiting frame 3 is composed of a retaining ring 3-1, a baffle 3-2 and a limiting pin 3-3. One end of the retaining ring 3-1 is fixed on the column 1-2, and the other end of the retaining ring 3-1 is an arc-shaped locking opening. The baffle 3-2 is installed on both ends of the arc-shaped locking opening via the limiting pin 3-3.

[0016] When using this invention, remove the baffle 3-2 from the limiting pin 3-3 of the auxiliary device to determine if the carrier 2 is closed. If the carrier 2 is locked, the weighed prepreg sample can be suspended in the recess on the crossbar 2-1. If the carrier 2 is unlocked, rotate the carrier 2 to make the crossbar 2-1 coaxial with the horizontal axis on the top frame 1-3, move the limiting ring 1-4 inward to lock the carrier 2, and then suspend the prepreg sample in the recess on the crossbar 2-1. After the test, wearing heat-resistant gloves, move the limiting ring 1-4 outward, rotate the carrier 2 to make the support rod 2-2 contact the retaining ring 3-1 on the limiting frame 3, and then place the baffle 3-2 on the limiting pin 3-3 to limit the rotation of the carrier 2. The prepreg sample can then be removed and placed in a desiccator to cool. The above-mentioned device allows testers to quickly remove prepreg samples without being burned by the adjacent column, and it is easy to operate.
