Description

Technical Field

[0001] This utility model relates to the technical field of sponge foaming feeding equipment, specifically a feeding mechanism for large-scale sponge foaming. Background Technology

[0002] Sponge foaming is a process in which porous sponge materials are produced through a chemical reaction of various foaming agents, additives, and base materials. Large sponges exceeding 20m in length are typically mixed, then extruded and fed into a continuous foaming device via a feeding mechanism. The feeding mechanism consists of a feeding trough connected to the front end of the foaming device and a pipeline connected to the extrusion device. Finally, the foam is formed within the continuous foaming device.

[0003] Currently, the feeding mechanism used for large-scale sponge foaming generally uses a single feeding port to enter the feeding trough. This structure is prone to uneven distribution of sponge. Furthermore, if there is no obstruction at the top of the feeding trough, the feeding efficiency cannot be improved, and feeding too quickly will cause the sponge to overflow. If a fixed baffle is used at the top of the feeding trough, the flexibility is poor. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a feeding mechanism for large-scale sponge foaming. Through two feeding ports, the sponge can be evenly fed into the feeding trough, thereby ensuring that the material enters the foaming area behind it evenly, thus ensuring the quality of the sponge. At the same time, a lifting baffle is provided at the top of the feeding trough to prevent the material from overflowing from the top of the feeding trough, thereby increasing the extrusion speed and improving production efficiency, thus solving the problems mentioned in the background art.

[0021] The feeding assembly includes an extrusion connector 1, a valve 2, a tee connector 3, and a hose 4. The bottom of the extrusion connector 1 is connected to the valve 2, and the end of the valve 2 away from the extrusion connector 1 is connected to the tee connector 3.

The upper part of the inclined plate 502 is bent to provide a platform 504. The inclined plate 502 and the platform 504 are connected to the side plates 503 on both sides. A groove 505 is formed between the first L-shaped plate 501 and the inclined plate 502. Two feed ports 6 are symmetrically provided at the bottom of the first L-shaped plate 501 in the groove 505. The two feed ports 6 are respectively connected to the end of the hose 4 away from the tee connector 3. A guide column 7 is provided on the upper surface of the side plate 503. A base 506 is provided at the bottom of the first L-shaped plate 501. Fixing plates 507 are provided on both sides of the bottom of the base 506. A first reinforcing plate 508 is provided between the fixing plate 507 and the base 506. The feeding trough 5 is installed and fixed through the base 506 and the fixing plate 507.

[0023] The limiting mechanism includes cylinders 8 and lifting baffles 9. There are two cylinders 8, which are respectively set on the outer surface of the side plate 503. The lifting baffles 9 are movably set in the feed trough 5. The lifting baffles 9 slide in contact with the inner wall of the first L-shaped plate 501 and the inner wall of the side plate 503 to ensure that the sponge will not overflow from the gap between the lifting baffles 9 and the first L-shaped plate 501 and the side plate 503. The upper surface of the lifting baffles 9 is provided with second L-shaped plates 10 on both sides. The upper part of the second L-shaped plates 10 is connected to the piston rod of the corresponding cylinder 8. The upper part of the second L-shaped plates 10 is also guided and cooperated with the corresponding guide column 7 through the guide sleeve 11. A second reinforcing plate 12 is provided between the lifting baffles 9 and the second L-shaped plates 10 to ensure the stability and structural strength between the second L-shaped plates 10 and the lifting baffles 9.

[0024] Working method and operating principle: First, connect the extrusion connector 1 to the discharge end of the extruder. Then, connect the three-way connector 3 to the inlet 6 inside the feeding trough 5 through the hose 4. When the sponge raw material is mixed and stirred, it is extruded from the extrusion connector 1 through the extruder. It enters the groove 505 through the valve 2, the three-way connector 3, the hose 4 and the inlet 6 on both sides of the feeding trough 5. Then, the cylinder 8 drives the second L-shaped plate 10 to rise and fall along the corresponding guide column 7, thereby driving the lifting plate to rise and fall. The material squeezed into the groove 505 of the feeding trough 5 moves to the rear of the feeding trough 5 through the obstruction of the lifting baffle 9 (the rear of the feeding trough 5 is a tunnel-type molding chamber with conveyor belts on the bottom and both sides. The sponge is continuously foamed in the tunnel-type molding chamber). Finally, a large sponge is obtained. This utility model has a reasonable structure. It is connected to two hoses 4 through a three-way connector 3. Two feed ports 6 are provided in the groove 505 of the feed trough 5. The sponge can be evenly fed into the feed trough 5 through the two feed ports 6, thereby ensuring that the material enters the foaming area behind it evenly, thus ensuring the quality of the sponge. At the same time, a lifting baffle 9 is provided at the top of the feed trough 5. The lifting baffle 9 can block the sponge material and prevent the material from overflowing from the top of the feed trough 5, thereby increasing the extrusion speed and improving production efficiency. At the same time, the height of the lifting baffle is controllable, which greatly improves the flexibility.
