Description

Technical Field

[0001] The utility model relates to the technical field of rebound cotton production devices, in particular to a vacuum packaging device for ordinary rebound cotton production. Background Art

[0002] Rebound cotton refers to slow rebound sponge, also known as inert sponge, slow elastic cotton, zero pressure sponge. According to different processes, it can be divided into polyether foaming series and MDI molding series. In the prior art, when rebound cotton is produced, it is often vacuum packaged to reduce its floor space and the size of the space occupied, so as to facilitate its transportation, etc., similar to stuffed items such as plush toys.

[0003] In the prior art, since plush toys have a lot of internal fillings, a vacuum pump is needed to perform vacuum treatment on the plush toys to reduce their overall volume. However, when the vacuum pump is performing vacuuming, mechanical vibrations will be generated. These vibrations will be transmitted to the pump casing and the surrounding environment, causing noise and affecting the health of the staff.

[0004] For example, a vacuum device for plush toy production and packaging disclosed in Chinese patent CN220743466U is provided, which places the plush toy in a vacuum bag, and then places the vacuum bag between the mounting frames, places the suction head in the vacuum bag, and then starts the two second hydraulic rods to move the pressing blocks relatively, thereby squeezing and sealing the opening of the vacuum bag through two rubber pads, and then pulls the restraining belt, and then clamps the clamping rod on the clamping block to limit the clamping rod, thereby fixing the plush toy on the base through the restraining belt, and after starting the vacuum pump, the suction head, the suction pipe and the connecting pipe are used together to The air in the vacuum bag is evacuated to put it in a vacuum state. The support block and the connecting pipe are used together to avoid shaking of the suction head. The first hydraulic rod is started to drive the hot pressing plate to move relatively, and the vacuum bag is hot-pressed and sealed to complete the packaging. When the vacuum pump is in operation, the damper and the spring are used together to reduce shock and buffer the mounting table, thereby reducing shock and buffering the vacuum pump. The noise generated by the vacuum pump can be isolated through the outer shell, and the noise can be absorbed by the sound-absorbing cotton to reduce the reflection and propagation of the noise, thereby reducing the impact of the noise on the surrounding environment and personnel.
