Description

Technical Field

[0001] The utility model belongs to the technical field of tire manufacturing, and particularly relates to a double-sided adhesive sound-absorbing cotton strip pasting, pressing and laminating integrated machine. Background Art

[0002] In recent years, with the gradual popularization of electric vehicles, consumers have higher and higher requirements for the comfort of automobiles. Especially, the tire noise generated during the driving of automobiles causes very uncomfortable feelings to the drivers and passengers. Therefore, most current tire manufacturers achieve the purpose of noise reduction by fitting sound-absorbing sponges on the inner wall of the tires, and the sound-absorbing tires are thus born.

[0003] At present, most of the sound-absorbing cotton strips fitted on the inner wall of the sound-absorbing tires on the market are attached manually after applying glue to the inner wall of the tires. The labor intensity of workers is high, the efficiency is low, and the attaching accuracy is poor. Although an automatic cotton attaching device for applying glue to the inner wall of the tire has been developed in recent years, not only the equipment investment is high and the floor area is large, but also the fitted tires need to be placed in a room with a certain temperature and humidity and left standing for more than 72 hours, resulting in a relatively high tire manufacturing cost. At the same time, there is also a risk of the sound-absorbing cotton falling off at the joint. Due to the cost advantage and the advantage of not being easy to de-cotton after fitting, a sound-absorbing sponge with double-sided adhesive has emerged on the market to replace the original ordinary sponge. Compared with ordinary cotton, the bottom of the double-sided adhesive cotton is self-adhesive with higher adhesiveness, not easy to de-cotton, and does not require additional glue application or special site for standing. The tire products with double-sided adhesive cotton have obvious cost advantages.

[0004] At present, there is no automatic fitting equipment available for fitting the double-sided adhesive sound-absorbing cotton on the market. Most of them adopt a fully manual cotton attaching process, with poor cotton attaching accuracy, low production efficiency, high labor intensity of workers, and low qualified product rate. In order to improve the cotton attaching accuracy and efficiency and reduce the labor intensity, it is urgent to develop a double-sided adhesive sponge fitting device with low equipment investment and small floor area to realize the semi-automatic fitting process of double-sided adhesive cotton.

[0011] Further, an upper pressure roller lifting component is arranged above the driving roller assembly. The upper pressure roller lifting component includes an upper pressure roller device slide plate which is fixedly connected to the upper guide rail slider. Two upper pressure rollers are fixedly arranged on the upper pressure roller device slide plate. The upper pressure roller device slide plate is driven by a third lifting cylinder to realize lifting. The third lifting cylinder is fixed on the frame through a cylinder mounting bottom plate.

[0012] The present utility model provides a double-sided adhesive sound-absorbing cotton strip laminating and pressing integrated machine, which has the following beneficial effects:

[0013] The pressure roller device component and the anti-sticking paper coiling device component are driven to rise and fall by the anti-sticking paper coiling device lifting component. At the same time, the first lifting cylinder in the pressure roller device component can drive the pressure roller and the sound-absorbing cotton strip edge guard to rise and fall synchronously. By reasonably calculating the effective stroke of the first lifting cylinder, no stroke adjustment is required during work, and it is convenient to load and unload tires of different specifications.
