Description

Technical field:

[0001] The utility model relates to the technical field of composite material processing equipment, and more specifically to a resin mixing platform. Background technology:

[0002] Composite materials are widely used in general aircraft due to their high strength, high hardness, easy molding, high fatigue resistance, and corrosion resistance. Efficient preparation of resin materials is a key factor in improving the competitiveness of aircraft manufacturers.

[0003] The resin mixing platform is made by mixing resin and curing agent in a certain ratio. In the early stage, two measuring cups were used to hold the resin and curing agent respectively, and then poured into the mixing and blending. This process is cumbersome to operate and human factors will also cause considerable errors.

[0004] Therefore, a frame is designed, on the upper part of which a resin barrel filled with resin liquid and a curing agent barrel filled with curing agent liquid are placed. However, this resin mixing platform has obvious disadvantages:

[0005] Before mixing the glue, it is necessary to use lifting equipment (electric hoist) to lift the resin barrel and curing agent barrel to the top of the resin platform. This process will waste a certain amount of manpower, and the lifting action and the light and heavy on the mixing platform will also have a certain safety.

[0006] The storage of resin and curing agent needs to be maintained at a certain temperature range (22℃-30℃), but there is no heating device on the existing frame. In winter, the air conditioner in the room can only be turned on, and the air conditioning equipment needs to be used for a long time, which wastes energy to a certain extent.

The control host is a conventional product that can be purchased directly and will not be described in detail here.

[0050] When in use, first open the two rear doors 20, manually push the discharge trolley 40 with the curing barrel 100 and the resin barrel 200 placed into the corresponding middle through groove, and press or close the front end face of the discharge trolley 40 against the corresponding front baffle 4, then, connect the discharge port at the bottom end of the curing barrel 100 with the feed end of the curing agent delivery pump 12 through a connecting pipe, and connect the discharge port at the bottom end of the resin barrel 200 with the feed port of the resin delivery pump 13 through a connecting pipe, and connect the air outlet ends of the connecting pipes fixed on the first high-precision pressure regulating filter 7 and the second high-precision pressure regulating filter 8 with the ventilation connector connected to the top plate of the curing barrel 100 or the resin barrel 200 through the connecting pipe; complete the installation and close the rear door 20.

[0051] The specific operation position is: first adjust the temperature: open the corresponding control panel of the control host (which is installed on the upper part of the front wall of the horizontal fixing plate 11), set the temperature range of the heating element 5 (22℃-30℃), and the inner wall of the main box 10 is installed with an insulation layer or insulation board. Among them, a temperature digital display is fixed on the front wall of the horizontal fixing plate 11, which is electrically connected to the control host through an electrical connection line. The parameters can be seen in the temperature digital display, and the stirring time (30 seconds) is set. After waiting for 15 minutes, enter the barreling (in order to make the cabinet reach 22℃-30℃). After the temperature exceeds 30℃, the control host can control the heating element 5 to stop heating.

[0052] Pressure regulation: adjust the first high-precision pressure regulating filter 7 and the second high-precision pressure regulating filter 8. Generally speaking, the pressure is constant and does not need to be adjusted again after the last use, unless the ratio is out of control during the ratio test.

[0053] Proportional test: Take two measuring cups (or other empty barrels), and align them with the bottom ends of the curing agent discharge pipe 1 and the resin discharge pipe 2 respectively (the bottom ends of the curing agent discharge pipe 1 and the resin discharge pipe 2 are vertically downward), then, turn on the switch of the control host to run the drive motor 14, and through the operation of the drive motor 14, the drive sprocket 141 runs, and through the operation of the chain 16, the transmission sprocket 15 rotates, so that the main shafts of the curing agent delivery pump 12 and the resin delivery pump 13 run to achieve delivery, then, pull the pull rod 91 to open the two control valves 9, so that the curing agent liquid and the resin liquid flow out of the curing agent discharge pipe 1 and the resin discharge pipe 2 into the measuring cups, and then, to achieve closure, pull the pull rod 91 to close the control valve 9, and then turn off the switch of the control host.

[0054] An electronic scale is placed on one side of the top surface of the top plate of the main box body 10. The electronic scale is used to peel and weigh. If the ratio of resin to curing agent meets 100:40±2, it is normal and can be used formally later. If not, readjust the pressure of the first high-precision pressure regulating filter 7 and the second high-precision pressure regulating filter 8, and then repeat the setting. (Note: The ratio test only needs to be performed at the start of work every day, or when changing the resin and curing agent).

[0055] When it is used formally, instead of only needing one mixing barrel, place it below the bottom of the quasi-curing agent discharge pipe 1 and the resin discharge pipe 2, and below the stirring paddle 51, and then pour the resin and curing agent into the mixing barrel in the same way as before, lift the mixing barrel so that the stirring paddle 51 is in the barrel, and then press the corresponding control button on the control panel to make the stirring motor 50 run, and the stirring paddle 51 stirs, stirring the materials in the mixing barrel, generally for 30 seconds, and then pour the mixed resin into the sample grid and register the resin use. (Note: Stirring sampling and registration need to be done every time to prevent the handling of unqualified products found in the test).

[0056] Then, test: after standing for 24 hours, take out the cured resin, scrape it with a utility knife to preliminarily determine the curing effect, and then test it with a DSC device (differential scanning calorimeter). The sample with a glass transition temperature of 90°C or above is qualified (such as Figure 7 , its DSC curve glass transition temperature is 98.18℃), otherwise it is unqualified (such as Figure 8 , its DSC curve glass transition temperature is 87.05℃), and parts made of unqualified cured resin need to be reworked or scrapped. (Of course, the probability of failure is extremely low, but in the aviation field, every part cannot have any defects).
