Problems solved by technology
However, due to the pursuit of speed in manual operation, dozens of products are often stacked together and pressed at the same time, resulting in some of the products not being pressed enough and the bonding effect is not good.
When using this product, the vehicle manufacturer will mainly encounter the situation that the tape and the sound-absorbing cotton are separated from the sound-absorbing cotton and cannot be used normally;
[0009] 3. The paste effect of double-sided pressure-sensitive tape is greatly affected by the temperature, and it may not be pasted in summer or winter

Embodiment Construction
[0023] Below, the structure and working principle of the present invention will be further described in conjunction with the accompanying drawings.
[0024] see figure 1 , which shows the internal structure of the sound-absorbing cotton gluing device of the present invention. The gluing device of the sound-absorbing cotton of the present invention comprises components such as a gluing tank 1 , an upper gluing roller 4 , and a pressure roller 5 . Hereinafter, they will be described respectively.
[0025] Rubber material 2 is contained in the glue tank 1 so as to supply glue for the upper rubber roller 4 . The shape of the glue tank 1 can be selected in various routines, for example, it is selected as a square or the like.
[0026] The upper rubber roller 4 is mounted on the rubber tank 1 and can be driven by a driving device (not shown in the figure) to rotate. The upper rubber roller 4 is located in the rubber tank 1, and the bottom of the upper rubber roller 4 is soaked in...

The invention discloses a gumming device for sound absorbing cotton. The device comprises a gum tank filled with gum, a gumming roller which is arranged on the gum tank in an erecting manner and can be driven by a driving device to rotate, and a pressing roller which is arranged in parallel above the gumming roller and connected with the gumming roller through a transmission device; the bottom of the gumming roller is soaked in gum; a gap through which the sound absorbing cotton passes is formed between the gumming roller and the pressing roller. The invention further discloses a gumming method for the sound absorbing cotton. With the adoption of the device and the method, the gumming efficiency of the sound absorbing cotton can be improved.
Description
technical field [0001] The invention relates to the field of sound-absorbing cotton. Specifically, the invention relates to a sound-absorbing cotton gluing device and a method for applying glue to the sound-absorbing cotton by using the gluing device. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection, new requirements have been put forward for automobiles. The international automobile industry has formulated a technical standard called NVH for short, namely, the three standards of noise, vibration and stability, which are commonly known as the "comfort" of riding a car. [0003] While the research on vehicle NVH continues to deepen, melted sound-absorbing cotton stands out as an excellent sound-absorbing and shock-absorbing material. Sound-absorbing cotton is widely used in car roofs, doors, engine hatches, instrument panels, trunk lids and other parts. During the assembly process, it is often required to b...
