Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a sponge rolling mechanism. Background Art

[0002] As consumers' requirements for low odor and high quality of automotive interior products are increasing, the ordinary processing technology and equipment structure of automotive interior composite materials can no longer meet market demand. Therefore, it is particularly important to change the traditional process and equipment structure.

[0003] Existing sponges need to be rolled up after production, but the existing rolling equipment is not perfect. When the sponge deviates during the sponge processing, the sponge direction needs to be adjusted manually. The tension during the sponge rolling process is uneven, and the product will have internal stress, which will cause the sponge to spread unevenly and fold. In addition, the existing rolling device does not squeeze the sponge when rolling it up. Since the sponge has a certain elasticity, the rolling device will deviate when rolling the sponge, causing the sponge to be wrinkled and unevenly rolled.

[0004] Chinese patent CN 211870914U discloses a polymer waterproof coiled material backing composite system, which includes an unwinding device, a backing cloth deviation correction device, a tension control device, a flattening roller, and a three-roll calender roller; the deviation correction device includes a position detector, a deviation correction controller, a deviation correction drive actuator, an unwinding frame, and a cylindrical guide rail; the tension control device includes a tension roller, a tension sensor, a tension controller, and a magnetic powder brake; the three-roll calender roller includes a bottom roller, a middle roller, and an upper roller; the extrusion end of the extrusion die is located between the bottom roller and the middle roller. The polymer waterproof coiled material backing composite system described in the utility model can solve the problems of material deviation, uneven spreading, and uneven tension during the composite processing of the backing cloth and the polymer waterproof coiled material, but it can keep the backing cloth and the waterproof coiled material substrate from being misaligned in the width direction through the deviation correction device, but it only controls the deviation problem during the winding process, and the material after winding will still deviate.
