[0002] Mattresses are an item placed between the human body and the bed to ensure that consumers get a healthy and comfortable sleep. Mattresses are made of a variety of materials, and mattresses made of different materials can bring different sleeping effects to people. Among them, spring mattresses are commonly used in modern times and have better performance. The core of the mattress is composed of springs and cloth covers that wrap the springs. The mattress has the advantages of good elasticity, good support, strong air permeability, and durability. The mattress production process involves the composite bonding and assembly of multiple materials. In this process, glue spraying devices are often used. Conventional glue spraying devices mainly include sprayers and brush coaters. Among them, brush coaters also include reciprocating brush coaters and roller brush coaters. Among them, the spraying glue coater works in a non-contact manner with the cotton cloth during operation. There is a certain distance between the glue outlet of the nozzle and the cotton cloth. The cotton cloth is sprayed with glue through the reciprocating motion of the nozzle. The position of the glue spraying is the arc part of the cotton cloth bypassing the auxiliary roller. After the glue spraying is completed, the core of the mattress is pushed to move and bond with the cotton cloth. Since the glue sprayed from the nozzle is in strips on the cotton cloth, the bonding range is small, which is not conducive to the fixation of the core of the mattress and the cotton cloth.

The flattening roller 31 has an arc-shaped recessed portion 311 that is adapted to and in contact with the spraying position. The arc-shaped recessed portion 311 is arranged around the flattening roller 31. The arc-shaped recessed portion 311 flattens the strip of glue. The center of the arc-shaped recessed portion 311 is located on the extension line of the connecting line of the auxiliary roller 5 and the glue, so as to evenly flatten the glue. An elastic member 33 is connected to the support plate 32. The support plate 32 has a transverse section and an inclined section. The inclined section extends toward the auxiliary roller 5. The inclined section supports the elastic member 33 and the flattening roller 31. The support plate 32 corresponds to the flattening roller 31 one by one. The slidable roller 31 is connected with the glue spraying device 2 to move, and the slidable roller 31 is in close contact with the glue 4 under the action of the elastic member 33, so that the slidable roller 31 rolls and flattens the glue, thereby preventing the slidable roller 31 from pushing the glue away during the movement. The elastic member 33 prevents the slidable roller 31 from slipping with the glue 4 during the rolling process. Wiping members 8 are provided on both sides of the spring pad core 1, and the wiping members 8 are sponges. There are four wiping members 8 in total. The two wiping members 8 on the left side of the spring pad core 1 wipe the two flattening rollers 31 on the right side, and the two wiping members 8 on the right side wipe the two flattening rollers 31 on the left side. Figure 1 The middle is a schematic diagram of the glue spraying device 2 moving to the right side.
