Description

Technical Field

[0001] This specification relates to the field of sponge bonding technology, and in particular to a multi-layer sponge bonding device. Background Technology

[0002] In the current sponge processing industry, the bonding of multi-layer sponges is a common production process. Traditionally, manual or simple mechanical pressing methods are used to press the glued multi-layer sponges together using rollers or flat plates to achieve a strong bond between layers. However, existing equipment has certain limitations in practical applications, mainly: the pressing method is mostly line contact or point contact, making it difficult to ensure uniform force on the multi-layer sponges during bonding, easily leading to problems such as weak adhesion or uneven thickness in some areas; furthermore, since traditional pressing equipment mainly uses pressing rollers, to ensure the pressing effect, the height of the pressing roller is less than the thickness of the sponge. Therefore, when the sponge first passes under the pressing roller, it needs to be manually pressed down. If the rotation of the pressing roller is not stopped, manually pressing the sponge under the pressing roller is dangerous; if the rotation of the pressing roller is stopped, the effect of the sponge pressing process will be affected. Summary of the Invention

The diameter of the power rollers is smaller than the inner diameter of the arc-shaped recesses. The pressing plate is inclined. The pressing belt wraps around the pressing plate and the two power rollers. The rotation of the power rollers drives the pressing belt to achieve a circumferential movement on the pressing plate. The upper and lower sides of the pressing plate support the pressing belt.

[0006] In some embodiments, the pressing plate has end plates fixed on both sides along the axis of the power roller, the end of the end plate is covered with an arc-shaped recess, a rotating shaft is fixed inside the power roller, the two ends of the rotating shaft are rotatably connected to the end plates on both sides, and a reinforcing frame is fixed on the outer side of the end plate.

The upper end of the lead screw is located inside the storage cylinder, and the lower end of the lead screw is fixedly connected to the guide block.

[0011] In some embodiments, a worm gear meshing with the worm wheel is provided on one side, a worm shaft is fixed inside the worm gear, and the two ends of the worm shaft are rotatably connected to the side wall of the housing. A connecting shaft is provided between the two housings, and the two ends of the connecting shaft are connected to the worm shaft through a coupling. An adjustment handle is fixed to the other end of one side of the worm shaft.

[0012] Beneficial effects: This invention uses the movement of a conveyor belt to transport multi-layered sponges coated with adhesive. When the multi-layered sponge passes the pressing assembly, the sponge comes into contact with the lower side of the pressing belt. Under the rotation of the inclined pressing belt, the multi-layered sponge is gradually pressed downward until it passes the lowest point of the pressing assembly. The pressing assembly then uses its pressure to achieve pressing. The lifting assembly can adjust the height of the pressing assembly to make it suitable for pressing sponges of different thicknesses. Attached Figure Description

[0030] In the current sponge processing industry, the bonding of multi-layer sponges is a common production process. Traditionally, manual or simple mechanical pressing methods are used to press the glued multi-layer sponges together using rollers or flat plates to achieve a strong bond between layers. However, existing equipment has certain limitations in practical applications, mainly: the pressing method is mostly line contact or point contact, making it difficult to ensure uniform force on the multi-layer sponges during bonding, easily leading to problems such as weak adhesion or uneven thickness in some areas; furthermore, since traditional pressing equipment mainly uses pressing rollers, to ensure the pressing effect, the height of the pressing roller is less than the thickness of the sponge. Therefore, when the sponge first passes under the pressing roller, it needs to be manually pressed down. If the rotation of the pressing roller is not stopped, manually pressing the sponge under the pressing roller is dangerous; if the rotation of the pressing roller is stopped, the effect of the sponge pressing process will be affected.
