[0002] Polyurethane is the full name of polyurethane, which is a general term for macromolecular compounds containing repeated carbamate groups on the main chain. It is formed by the addition polymerization of organic diisocyanates or polyisocyanates with dihydroxy or polyhydroxy compounds. Generally, polyurethane is a polymer made of polyisocyanates and polyether polyols or polyester polyols or / and small molecule polyols, polyamines or water, chain extenders or crosslinking agents. After the polyurethane resin is produced, it needs to be filled into the material barrel through the filling equipment.

[0003] A polyurethane resin filling device with announcement number CN220483639U has the following defects during use:

[0004] The utility model limits the position of the tank body by a limit plate, so that the tank body is aligned with the injection tube, and drives the two-way thin rod to rotate by starting the stepping motor, and adjusts the distance between the two sets of limit plates, so that the device is suitable for tank bodies of different sizes, thereby realizing the tank body limiting function of the device, and limiting the position of the tank body so that the tank body is accurately aligned with the injection tube, which is convenient for filling the device with polyurethane resin. In actual use, multiple tank bodies are filled at the same time. If it is controlled only by the stop valve, it is necessary to open and close each filling port that needs to be used separately, and multiple operations are required, which is inefficient. For this reason, we propose a polyurethane resin filling device. Utility Model Content

The connecting ring 9 is a ring-shaped shell structure, and a plurality of second connecting holes 10 are provided on the inner wall surface of the connecting ring 9. Through the design of the connecting ring 9, when there is no collecting device at the corresponding position, the inner wall of the connecting ring 9 will block the first connecting hole 8, so that the internal resin remains inside the vertical tube of the first filling tube 7. When there is a collecting device at the bottom, the first connecting hole 8 will be restricted by the height of the collecting device after falling to a certain position, so that it moves upward. When the second connecting hole 10 is aligned with the first connecting hole 8, the internal resin can fall normally, which reduces the time of a single adjustment compared with valve control.

[0023] A second filling tube 11 is fixedly installed on the bottom surface of the connecting ring 9. The second filling tube 11 is connected to the connecting ring 9. The second filling tube 11 is composed of a cylindrical tube and a conical tube. A ball 12 is sleeved inside the conical tube part of the second filling tube 11. Through the design of the ball 12, since the resin is a viscous liquid, a single conical tube is prone to accumulate resin at the opening to cause the opening to be blocked. The ball 12 can limit the flow rate while being able to avoid blockage by manually rotating the ball 12 when blocked. A fixing plate 13 is fixedly installed on the bottom surface of the vertical tube part of the first filling tube 7.

The first spring 15 is limited by the fixing plate 13 and the disc part of the first connecting rod 14. Through the design of the first spring 15, the position of the connecting ring 9 and the second filling tube 11 can be limited, so that when there is a collecting device below that forces the connecting ring 9 and the second filling tube 11 to shift, the elastic force of the first spring 15 can make the connecting ring 9 The second filling tube 11 returns to its original position, which is convenient for the next filling. The second spring 17 is fixedly installed inside the connecting tube 3. Through the design of the second spring 17, after the pressing device is filled, the external force disappears and the connecting tube 3 is returned to its original position by the elastic force of the second spring 17, which is convenient for the next pressing and filling. The bottom end of the second connecting rod 16 is fixedly installed with a fixing rod 18, which passes through the top surface of the first connecting plate 2, and the outer wall surface of the fixing rod 18 is provided with a thread, and the outer wall surface of the fixing rod 18 is threadedly connected with a nut 19, and the interior of the fixing box 6 is fixedly installed with The heating ring 20 is a circular ring shell, and a plurality of heating resistors 21 are fixedly installed inside the heating ring 20. Through the design of the heating resistors 21, the heating ring 20 can be heated to avoid the solidification of the resin stored in the fixed box 6 for a long time, which makes it inconvenient for the resin to flow out. A plurality of fixing seats 22 are fixedly installed on the top surface of the bottom plate 1. Through the design of the fixing seats 22, the position of the filling container can be fixed to avoid the relative movement of the container during use affecting the actual filling effect.
