Embodiment 1

[0040] A kind of damping sheet release paper gluing device of the present embodiment, such as figure 1 As shown, it includes an operation table 1, a release paper roll holder 2 and a water-based glue barrel 5, and also includes a thinning roller 3 and a water-based glue thinning belt 6, wherein: the operation table 1 has a slightly downward-sloping structure, and the release paper roll holder 2 is fixed on The bottom of the console 1; the water-based glue bucket 5 and thinning roller 3 are fixed on the upper surface of the console 1 according to the process sequence; one end of the water-based glue thinning belt 6 is fixed on the bottom of the water-based glue bucket 5, and the discharge port 51 is flushing the water-based glue thinning belt 6. The other end is fixed on the surface of the console 1 at the bottom of the thinning roller 3; after the release paper is unfolded by the release paper roll holder 2, the end passes through the bottom of the thinning roller 3, and the en...

Embodiment 2

[0043] A damping sheet release paper gluing device of this embodiment has the same basic structure as that of Embodiment 1, and the improvement is that it also includes a pressure roller 4 that is parallel to the thinning roller 3 and arranged along the process direction. Distributed with 8 grooves 42, the length of the pressing roller 4 is 330mm, the groove spacing is 30mm, the width is 10mm, and the depth is 2.5mm. Squeeze adjustment mechanisms 41 are arranged at both ends to adjust the gap between the pressing roller 4 and the release paper. between gaps. Pressure-sensitive adhesive viscosity ≤ 15g / min, fluidity 2.0.

[0044] A method for applying glue to the release paper by the damping sheet release paper gluing device of this embodiment, the steps are:

[0045] A. Pull out the end of the silicon-coated release paper on the release paper roll stand 2, pass it through the bottom of the thinning roller 3, and then pass through the bottom of the pressure roller 4, and the s...

Embodiment 3

[0053] The basic structure of the damping sheet release paper gluing device of this embodiment is the same as that of Embodiment 2, and the improvement is that: an agitator 7 is installed in the water-based glue bucket 5; the bottom end of the agitator 7 is fixedly connected with a star-shaped stirring blade 52; the spacing of the grooves 42 is 4cm;

[0054] When the damping sheet release paper gluing device of this embodiment is used specifically, in step B, the agitator 7 is turned on at the same time, the star-shaped agitating blade 52 forms a vortex for the agitation of the rubber material, and a stable flow rate is formed for the discharge port 51. Discharging; in step D, the amount of glue flow can be controlled by reducing the stirring speed of the agitator 7 .

Abstract

The invention discloses a glue spreading device and method of isolation paper of a damping fin and belongs to the field of machining auxiliary equipment of an automobile damping fin. The glue spreading device comprises an operation platform, an isolation paper roll holder and an aqueous glue barrel, and further comprises a dilution roller and an aqueous glue dilution belt, wherein the operation platform is of a slight declination type structure; the isolation paper roll holder is fixed at the bottom of the operation platform; the aqueous glue barrel and the dilution roller are fixed on the upper surface of the operation platform according to a process sequence; one end of the aqueous glue dilution belt is fixed at the bottom of the aqueous glue barrel, and a discharging hole is aligned to the aqueous glue dilution belt; the other end of the aqueous glue dilution belt is fixed on the surface of the operation platform at the bottom of the dilution roller; and after the isolation paper is unfolded by the isolation paper roll holder, the end of the isolation paper penetrates out from the bottom of the dilution roller, and the end of the aqueous glue dilution belt is in seamless contact with the isolation paper. According to the glue spreading device and method of the isolation paper of the damping fin, disclosed by the invention, the uniformity of aqueous glue dilution is improved; after dried aqueous glue is in contact with the damping fin, the jointing tightness can be guaranteed, and the problems that the damping fin is stuck due to too early separation and the damping fin is not easy to separate due to non-uniform stress are prevented.

Description

technical field [0001] The invention relates to the field of auxiliary processing equipment for automobile damping sheets, in particular to a gluing device and method for damping sheet release paper. Background technique [0002] With the advancement of manufacturing technology in the automobile industry, people are paying more and more attention to the noise control in passenger cars. Due to the relatively weak domestic automobile manufacturing technology foundation, it is difficult to design the elements that affect the NVH quality of the vehicle in place during automobile R&D and design. Always carry out NVH rectification after the finished car comes out, mainly through the use of sound insulation materials such as the interior floor and interior decoration of the car, to block the external noise and vibration from being transmitted to the passenger compartment, so that the noise inside the car is greatly reduced, so it is harmful to the car. The amount of sound insulatio...
