[0030] In this embodiment: when all the polyurethane sealant is filled into the storage tank 6, a portion of the polyurethane sealant flows into the feeding cylinder 507 through the connecting pipe 503.

[0031] Please refer to this carefully. Figure 5 The cross 506 is fixedly connected to the feeding cylinder 507, and the rotating cross 506 is used to drive the feeding cylinder 507 to move around the output shaft of the second motor 504.

[0032] In this embodiment: the output shaft of the second motor 504 in operation drives the cross 506 to rotate, and the rotating cross 506 drives multiple feeding cylinders 507 to rotate along the track of the chute 505.

[0033] Please refer to this carefully. Figure 3 The aligned connecting pipe 503 and feeding cylinder 507 are used to feed polyurethane sealant, and the aligned feeding port 508 and feeding cylinder 507 are used to discharge polyurethane sealant.

[0034] In this embodiment: one of the feeding cylinders 507 is rotated to a position aligned with the connecting pipe 503, while the other feeding cylinder 507 is rotated to a position aligned with the feeding port 508. Then, a portion of the polyurethane sealant in the storage tank 6 flows into one of the feeding cylinders 507 through the connecting pipe 503, and another portion of the polyurethane sealant filled inside the other feeding cylinder 507 flows into the feed pipe 3 through the feeding port 508.

[0035] Please refer to this carefully. Figure 3 The stirring mechanism 7 includes a support 701, a first motor 702, a stirring rod 703, and a stirring blade 704;

[0037] In this embodiment: the first motor 702 is powered on and operated, so that the output shaft of the first motor 702 drives the stirring rod 703 to rotate. The rotating stirring rod 703 drives the stirring blade 704 to rotate. Since the stirring blade 704 has a spiral structure, the rotating stirring blade 704 stirs the polyurethane sealant inside the storage tank 6, so as to avoid the polyurethane sealant in the storage tank 6 from easily settling during filling.

[0038] Please refer to this carefully. Figure 3 The first motor 702 in operation is used to drive the stirring rod 703 to rotate, and the rotating stirring rod 703 is used to drive the stirring blade 704 to rotate.

[0041] In this embodiment: Since the stirring blade 704 has a spiral structure, the rotating stirring blade 704 stirs the polyurethane sealant inside the storage tank 6.

[0042] Working principle: First, all the polyurethane sealant is filled into the storage tank 6. At this time, the first motor 702 is powered on and started. The output shaft of the running first motor 702 drives the stirring rod 703 to rotate. The rotating stirring rod 703 drives the stirring blade 704 to rotate. Since the stirring blade 704 has a spiral structure, the rotating stirring blade 704 stirs the polyurethane sealant inside the storage tank 6, preventing the polyurethane sealant in the storage tank 6 from settling during filling.

[0043] At this point, the second motor 504 is powered on and started, causing the output shaft of the running second motor 504 to drive the cross 506 to rotate. The rotating cross 506 then drives multiple feeding cylinders 507 to rotate along the slide groove 505. One of the feeding cylinders 507 is rotated to a position aligned with the connecting pipe 503, while another feeding cylinder 507 is rotated to a position aligned with the feeding port 508. Then, part of the polyurethane sealant in the storage tank 6 flows into one of the feeding cylinders 507 through the connecting pipe 503, and another part of the polyurethane sealant filled in the other feeding cylinder 507 flows into the feed pipe 3 through the feeding port 508, and then into the feed vessel 1.
