Description

Technical Field

[0001] The utility model relates to the technical field of automobile sponge pad production devices, in particular to a rolling device for producing automobile seat sponge pads. Background Art

[0002] With the rapid development of the automobile industry, the comfort and safety of automobile seats have been increasingly emphasized. As an important part of the seat, the production quality of the sponge pad directly affects the comfort and durability of the seat. At present, the production of automobile seat sponge pads mainly adopts the rolling process to achieve the required density and shape. However, there are some defects in the existing technology that need to be improved;

[0003] When the rolling device in the existing technology is in use, since both pressing rollers are fixed, the gap between the pressing rollers is fixed and cannot be adjusted according to the thickness and hardness of the sponge pad. As a result, when producing sponge pads of different specifications, it is necessary to frequently replace the pressing rollers or adjust the equipment settings, increasing the production cost and time. When the pressing rollers with a fixed gap face the unevenness of the sponge material, a uniform rolling effect cannot be achieved, easily causing local over-high or over-low density of the sponge pad, affecting the comfort and durability of the seat. Therefore, a rolling device for producing automobile seat sponge pads is proposed to overcome the above defects. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rolling device for producing automobile seat sponge pads, which realizes the function of adapting to sponge pad materials with different thicknesses and hardnesses by adjusting the gap between the adjusting roller and the cross roller through the movement of the rectangular block.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model is a rolling device for producing automobile seat sponge pads, including a carrier table, on which a U-shaped frame is installed. Adjusting grooves are respectively opened in the two side plates of the U-shaped frame. Rectangular blocks are slidably fitted in the two adjusting grooves. An adjusting roller is rotatably arranged between the two rectangular blocks. The tops of the two rectangular blocks are connected with a U-shaped plate. A screw rod is threadedly penetrated through the U-shaped frame and is rotatably fitted on the U-shaped plate.

[0007] A guiding part is installed inside the U-shaped frame. The guiding part has two cross plates, which are respectively connected to the two side walls of the U-shaped frame. Drums are rotatably arranged between the two ends of the two cross plates. A transmission belt is fitted on the two drums. Limiting belts are installed on both sides of the transmission belt. A third motor is installed on the outer surface of the cross plate, and the output end of the third motor is connected to the drum.

[0008] Preferably, a cross roller is rotatably arranged inside the U-shaped frame. The cross roller is located at the bottom of the adjusting roller. A second motor is slidably fitted on the outer surface of the U-shaped frame, and the output end of the second motor is connected to the adjusting roller.

[0009] Preferably, sliding grooves are formed in both side plates of the U-shaped frame, and the two sliding grooves communicate with the adjusting groove.

[0010] Preferably, two sliding blocks are installed on the outer surface of the rectangular block, and the two sliding blocks are respectively slidably engaged in the corresponding sliding grooves.

[0011] Preferably, two side plates are installed on the carrier table, two pressure rollers are rotatably arranged between the two side plates, a first motor is installed on the outer surface of the side plate, and the output end of the first motor is connected to the pressure roller.

[0012] Preferably, gears are fitted at one ends of the two pressure rollers, and the two gears are meshed with each other.

[0013] The utility model has the following beneficial effects:

[0014] 1. Under the combined action of the rectangular block and the U-shaped plate, by rotating the screw rod with the two rectangular blocks, the U-shaped plate moves downward to the bottom, and the adjusting roller moves downward to the bottom. At this time, the gap between the adjusting roller and the cross roller is adjusted, and then the sponge pad is rolled, ensuring that uniform and appropriate pressure can be applied during the rolling process, thus effectively avoiding over-compression or under-compression of the sponge pad, significantly improving the product yield and consistency, reducing the time required for replacing the pressure roller or adjusting the equipment settings, thereby improving the operation efficiency of the production line, reducing the downtime, and significantly improving the production efficiency;

[0015] 3. Under the action of the guiding part, the sponge pad that has been initially rolled by the two pressure rollers falls onto the conveyor belt. At this time, the sponge pad is conveyed between the adjusting roller and the cross roller through the conveyor belt, and the sponge pad is limited by the limiting belt, which facilitates the conveying of the sponge pad, ensures the seamless connection of the sponge pad from the initial rolling to the re-rolling process, reduces the waiting time in the intermediate links, improves the coherence of the entire production process, reduces the need for manual handling, further automates the production process, and reduces the dependence on manual operation.
