Description

Technical Field

[0001] This utility model relates to the field of sound-absorbing cotton coating technology, and in particular to a mechanism for coating automotive sound-absorbing cotton. Background Technology

[0002] In the production process of automotive interiors, sound-absorbing cotton needs to be bonded to the corresponding parts of the car body or other substrates through an adhesive coating process in order to perform its noise reduction and sound insulation functions. Automotive sound-absorbing cotton adhesive coating equipment is usually equipped with a conveying mechanism and an adhesive coating mechanism. The conveying mechanism transports the sound-absorbing cotton to the adhesive coating station, and then the adhesive coating mechanism completes the application of adhesive. The accurate positioning of the sound-absorbing cotton is a key prerequisite for ensuring the uniformity of adhesive coating and the reliability of bonding.

[0003] Existing equipment mostly relies on manual placement or fixed blocks to position the sound-absorbing cotton. Manual positioning has poor consistency, and fixed blocks cannot be adapted to different specifications of sound-absorbing cotton and are prone to material deformation. It is difficult to achieve precise centering, resulting in misalignment of the adhesive components, such as missed coating and displacement, which affects the bonding quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automotive sound-absorbing cotton gluing mechanism, which aims to improve the problem that existing equipment relies heavily on manual placement or fixed blocks to position the sound-absorbing cotton, making it difficult to accurately center the sound-absorbing cotton.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A sound-absorbing cotton coating mechanism for automobiles includes a bracket. A first motor is fixedly connected to the outside of the bracket, and a conveyor belt is connected to the output end of the first motor. A slide rod is fixedly connected inside the bracket, and a clamping mechanism is rotatably connected inside the slide rod. The clamping mechanism includes a second support rod, which is rotatably connected to the outside of the slide rod. A first support rod is rotatably connected to both ends of the second support rod.

A fixed rod is set on one side of the first slider and is rotatably connected to the first support rod. The second support rod is used to drive the first support rods on both sides, thereby driving the clamps on both sides to clamp the sound-absorbing cotton body in the center and then release it. The drive component is used to drive other components to adjust the position of the sound-absorbing cotton body.

[0007] Preferably, the drive assembly includes a second fixing block, one end of which is rotatably connected to the inside of the slide rod, and the other end of which is fixedly connected to an electric push rod. The output end of the electric push rod is connected to a first fixing block, and one end of the first fixing block is rotatably connected to a third support rod.

Specifically, in this embodiment, one end of the second fixing block 608 is cylindrical and rotates inside the slide rod 10, while the other end is square to facilitate the fixed connection of the electric push rod 607. The electric push rod 607 is used to drive the first fixing block 605 to rotate. The first fixing block 605 and the second fixing block 608 have the same structure but opposite direction and are used to drive the third support rod 606 to rotate, thereby driving the second support rod 604 and other components to center and clamp the sound-absorbing cotton body 5.

Specifically, the second fixing rod 12 is a directional fixing block that facilitates the first spring 13 to reset and fix it. The two sides of the second fixing rod 12 have extended parts that facilitate manual pushing. Whether disassembling or assembling, the second fixing rod 12 must be pushed upwards, thereby improving the convenience of replacing the pressure roller 4. Example

[0025] Working principle: When it is necessary to center the sound-absorbing cotton body 5, the electric push rod 607 is turned on to drive the first fixed block 605 and the second fixed block 608 to rotate, thereby driving the third support rod 606 to rotate inside the slide rod 10, which in turn drives the second support rod 604 to rotate inside the slide rod 10, further driving the first support rod 603 to rotate, thereby driving the first slider 602 to slide outside the slide rod 10, and thus driving the clamping plate 601 to move closer to or further away from the outside of the sound-absorbing cotton body 5, so that the sound-absorbing cotton body 5 can be centered, achieving the effect of facilitating the glue application tube 7 to apply glue to the sound-absorbing cotton body 5; When the pressure roller 4 needs to be replaced, push the second fixing rod 12 upward to make it slide inside the first fixing rod 11 and the third fixing rod 15, while squeezing the first spring 13, so that the second fixing rod 12 moves away from the inside of the first fixing rod 11. Then pull the first fixing rod 11 to slide inside the third fixing rod 15, and then remove the first fixing rod 11 and the pressure roller 4. When the pressure roller 4 needs to be installed, align the upper end of the slot of the first fixing rod 11 with the circular groove opened inside the third fixing rod 15, slide the first fixing rod 11 inside the third fixing rod 15, and then push the second fixing rod 12 upward to slide inside the third fixing rod 15. When the first fixing rod 11 slides to the appropriate position, release the second fixing rod 12, and the first spring 13 will push the second fixing rod 12 to slide inside the first fixing rod 11 and the third fixing rod 15, thereby fixing the position of the first fixing rod 11 and the pressure roller 4, achieving the effect of quickly replacing the pressure roller 4 without tools.
