Description

Technical Field

[0001] This utility model relates to the technical field of waterbird shell molding equipment, and in particular to a resin injection device for shell pressing. Background Technology

[0002] During geophysical survey vessel operations, several cables are towed by the vessel to receive geological information. Along these cables, which can stretch for thousands of meters, hundreds of various types of waterbirds are attached to control cable depth and spacing, measure sound velocity and water velocity, and calculate cable morphology in real time. There are many types of waterbirds; one type has a cylindrical shell made of resin, requiring compression molding equipment. The resin used is cast polyurethane, which is liquid before molding and solidifies after reaction. During shell pressing, resin injection equipment is used to inject the cast polyurethane into the molding die. Because cast polyurethane has a high viscosity, it is prone to trapping air bubbles, affecting the quality of the pressed product. Furthermore, existing resin injection equipment has low injection efficiency and is relatively difficult to operate, impacting work efficiency. Utility Model Content

The first feed port 120 is provided with a feed valve 121, which is connected to a feed pipe 122. The bottom of the mixing tank 100 is provided with a first discharge port 140, which is connected to the inlet of a conveying device 200. The air inlet 130 is connected to a vacuum device 300 through a pipe. The feeding assembly 400 includes a weighing device 410. A column 420 is provided on one side of the weighing device 410. A lifting plate 430 is slidably mounted on the column 420 facing the weighing device 410. A driving device 440 is provided on the column 420, and the driving device 440 is driven to the lifting plate 430 to drive the lifting plate 430 to rise or fall. A feeding pipe 450 passes through the end of the lifting plate 430 away from the column 420. The feeding pipe 450 is fixedly connected to the lifting plate 430, and the top end of the feeding pipe 450 is connected to the feed pipe 122 via a flexible hose 460. The top and bottom of the curing agent tank 500 are respectively provided with a second inlet 510 and a second outlet 520. A first metering pump 530 is provided at the second outlet 520, and the outlet of the first metering pump 530 is connected to the feed pipe 122 via a pipe. Each pigment tank 600 has a third inlet 610 and a third outlet 620 at its top and bottom, respectively. A second metering pump 630 is installed at the third outlet 620, and the outlet of the second metering pump 630 is connected to the inlet pipe 122 via a pipe. The temporary storage tank 700 has a fourth inlet 710 and a fourth outlet 720 at its top and bottom, respectively.

The curing agent is added to the curing agent tank 500 through the second inlet 510, and the pigment is added to the pigment tank 600 through the third inlet 610. The resin tank is placed on the weighing device 410. The control drive device 440 drives the lifting plate 430 to lower the feeding pipe 450, allowing the feeding pipe 450 to insert into the resin in the resin tank. The vacuum device 300 is activated, and the feed valve 121 is opened. Under negative pressure, the resin enters the mixing tank 100 through the feeding pipe 450, hose 460, and feed pipe 122. When the weighing device 410 displays the resin feeding amount, the control drive device 440 drives the lifting plate 430 to raise the feeding pipe 450, completing the resin feeding. Then, the first metering pump 530 is controlled to add the curing agent from the curing agent tank 500 into the mixing tank 100 through the feed pipe 122. The second metering pump 630 is then controlled to add the pigment from the pigment tank 600 into the mixing tank 100 through the feed pipe 122. After feeding, the feed valve 121 is closed. The stirring assembly 110 is controlled to stir the material in the mixing tank 100. Under negative pressure, the air bubbles in the material will gradually disappear. After stirring for a certain period, the vacuum device 300 and the stirring assembly 110 are closed, and the feed valve 121 is opened to release the negative pressure in the mixing tank 100. Then, the conveying device 200 is controlled to add the material from the mixing tank 100 into the temporary storage tank 700. The amount of material in the temporary storage tank 700 can be observed through the observation window 740. When the required amount for pressing is reached, the conveying device 200 is closed, and the conveying pump 730 is controlled to convey the material in the temporary storage tank 700 into the pressing mold for pressing. Several scale marks 741 allow the operator to easily monitor the conveying volume of the conveying pump 730.

The plurality of stirring fins 113 are evenly distributed on the stirring rod 112 along the extension direction of the stirring rod 112. A discharge valve 141 is installed at the first discharge port 140, and the discharge valve 141 is connected to the inlet of the conveying device 200.

The end of the lifting plate 430 facing the column 420 is threadedly connected to the lead screw 442. When the lifting plate 430 is driven to rise and fall, the drive motor 441 is controlled to drive the lead screw 442 to rotate, and the lead screw 442 drives the lifting plate 430 to slide along the groove 421, thereby driving the feeding pipe 450 to rise and fall.
