Description

Technical Field

[0001] This utility model relates to the field of foam defoaming technology, specifically a polyurethane foam defoaming device. Background Technology

[0002] Foam is a porous material formed by a large number of tiny air bubbles dispersed in a solid matrix. Due to its unique structure, foam has excellent properties such as lightweight, high elasticity, heat insulation, sound absorption, and shock absorption. Polyurethane is a polymer material produced by the reaction of polyols and isocyanates, possessing excellent flexibility and versatility. Polyurethane foam is a porous foam made of polyurethane materials, and a polyurethane foam defoaming device is a specialized device used to remove air bubbles generated during the production of polyurethane foam, thereby improving the density and quality of the foam.

[0003] The patent document with announcement number CN221022042U describes a polyurethane foam defoaming device. The described scheme uses a pump to transport liquid polyurethane foam raw material into a feed cylinder. Then, an external drive motor drives the turntable to rotate, causing an eccentric roller to rotate against the inner wall of the feed cylinder. Since some of the liquid polyurethane foam raw material enters the gap between the eccentric roller and the feed cylinder, the air bubbles trapped in the liquid polyurethane foam raw material are removed by the extrusion of the eccentric roller.

[0004] The aforementioned technology has the problem of not being able to easily remove the processed polyurethane foam. Leaving it in the device for a long time may cause the foam to over-cured or deform, affecting the size and performance of the final product. If it is forcibly removed, it may damage the device and the foam itself, resulting in an increased defect rate. Utility Model Content

By activating the first electric push rod 501, it drives the L-shaped plate 502 to rise and fall, thereby driving the separation tank 200 to rise and fall.

[0029] In one embodiment, such as Figure 1 , Figure 2 and Figure 3As shown, the rotating assembly includes a support frame 601, which is fixedly connected to the bottom of the base plate 100. A rotating column 602 is rotatably connected inside the support frame 601. The other end of the rotating column 602 passes through the base plate 100 and the electric heating plate 300 and is slidably connected inside the hollow column 400. A drive motor 603 is provided at the bottom of the support frame 601. Synchronous pulleys are provided at the output end of the drive motor 603 and the lower middle part of the rotating column 602. A synchronous belt 604 is provided between the two synchronous pulleys. By starting the drive motor 603, it drives one synchronous pulley to rotate. Then, under the action of the synchronous belt 604, it drives the other synchronous pulley to rotate, thereby driving the rotating column 602 to rotate. Then, under the limitation of the hollow column 400, it drives the electric heating plate 300 and the separation tank 200 to rotate.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, the fixing component includes several buckles 701, which are all located in the lower part of the separation tank 200. The bottom of the electric heating plate 300 is provided with several locking blocks 702. By pulling the buckles 701, they are brought close to the locking blocks 702, thereby limiting and fixing the electric heating plate 300.

[0031] In one embodiment, such as Figure 1 and Figure 2 As shown, the pressing assembly includes two second electric push rods 801. Each of the two second electric push rods 801 is located on the top of the separation tank 200. The output end of the second electric push rod 801 is provided with a pressure plate 802.

[0035] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the base plate 100 is provided with support legs on all four sides, so that the base plate 100 can support the base plate 100.

[0036] The above embodiment discloses a polyurethane foam densification and defoaming device. Polyurethane foam raw material is added through the feed inlet 900. Then, the drive motor 603 is activated, causing one synchronous wheel to rotate. Subsequently, under the action of the synchronous belt 604, another synchronous wheel rotates, thereby causing the rotating column 602 to rotate. Then, under the limitation of the hollow column 400, it causes the electric heating plate 300 and the separation tank 200 to rotate, thereby removing air bubbles inside the polyurethane foam raw material. Next, the second electric push rod 801 is activated, causing two pressure plates 802 to rise and fall, bringing them close to the polyurethane foam raw material and pressing it to ensure its density. Then, the electric heating plate 300 is activated to heat the polyurethane foam raw material, thereby curing it. After curing to a certain extent, the buckle 701 is pulled away from the locking block 702. Then, the first electric push rod 501 is activated, causing the L-shaped plate 502 to rise and fall, thereby causing the separation tank 200 to rise and fall, allowing the polyurethane foam at the top of the electric heating plate 300 to be removed.
