A sound insulation cotton gluing machine

Abstract

The invention discloses a sound-insulating cotton gluing machine, which belongs to the technical field of gluing machines. The invention includes a frame, on which a glue spreading mechanism is arranged; a glue discharging mechanism, a recycling mechanism and a belt conveying mechanism are also included, and the recycling mechanism includes a waste rubber conveying pipe, a waste rubber pump, a glue mixing tank, and a waste rubber recovery tank , original rubber hose, mixing and stirring blades, etc.; the glue delivery mechanism includes a transmission screw, a glue delivery device, a deceleration motor and a glue delivery hose; the belt transmission mechanism includes a transmission platform, a transmission belt and a transmission roller, and each transmission belt at the end of the transmission platform Pads are fixed on both sides of the rubber storage tank; the outer side of the rubber storage tank is wrapped with a heating layer and an insulation layer from the inside to the outside; The surface of the rubber roller is provided with multiple sections of W-shaped stripes along the axial and radial directions. The invention realizes the functions of simultaneously overcoming the problems of uneven glue application and easy overflow of glue from both ends of the rubber roller during the rubber skin coating process.

Description

technical field [0001] The invention relates to the technical field of gluing machines, and more specifically, to a sound-insulating cotton gluing machine. Background technique [0002] The main noise source of the outdoor unit of the air conditioner is the compressor part. At present, the noise reduction technology of the outdoor unit of the air conditioner is mainly realized by preventing the sound wave from propagating. Existing air-conditioning outdoor units use sound-insulating cotton, wrapping a circle of sound-insulating cotton around the cylinder body of the compressor, and wrapping a circle of sound-insulating cotton around the periphery of the pipeline, so as to absorb the sound wave energy of each frequency range radiated from the compressor to achieve a large Noise reduction effect. The sound insulation cotton on the market is mainly composed of two layers of material, one layer is rubber skin, and the other layer is felt. The felt is attached to the rubber ski...

Problems solved by technology

[0003] The existing gluing machine relies on three rubber rollers to rotate counterclockwise to make the glue evenly coated on the surface of the rubber skin, but there is a gap between the two ends of the rubber rollers, and the glue is easy to overflow from the two ends of the rubber rollers, resulting in waste of glue and overflow The glue is not easy to clean

Aiming at the phenomenon that the glue on the gluing machine is easy to overflow from both ends of the rubber roller and cause glue waste, related solutions have been disclosed in the prior art, such as Chinese patent application number: 2014104451359, application date: September 3, 2014, invention The name of the creation is: plywood gluing device. The application discloses a plywood gluing device that is convenient for recycling waste glue. The mechanisms are respectively located above and below the frame; the glue making mechanism includes a barrel, a mixer, a hopper and a discharge trough, and the glue applying mechanism includes an upper glue roller group and a lower glue roller group, and the upper glue roller group is located at the lower glue roller. Above the roller, the upper rubber roller group includes a pair of rubber rollers, which are arranged horizontally and parallel. located below the discharge chute

The deficiencies of this application are: (1) the recycling mechanism only includes recycling bins, and if the waste rubber falls into the recycling bin and is not reused in time, it is easy to solidify and stick in the recycling bin, causing the waste rubber recovery rate to be low and not It is conducive to the reuse of waste glue; (2) Although the glue overflowing from both ends of the rubber roller is recycled, the overflowing glue is easy to stick to the two ends of the rubber roller and is not easy to clean

The weak point of this application is: (1) upper gluing part is made up of a plurality of glue nozzles in this application, and the axial length of roller group is longer, and a large amount of glue nozzles must be set at the upper end of roller group to guarantee The glue is evenly distributed on the surface of the core material, which makes the design and arrangement complex and cumbersome to operate; (2) For core materials of different widths, the number, position and spacing of the glue nozzles need to be manually adjusted to ensure that the glue is evenly distributed on the surface of the core material, and the operation is more cumbersome

[0007] (1) Cannot effectively recycle and reuse the waste rubber produced in the rubber skin coating process;

[0008] (2) Uneven glue application during the rubber skin coating process;

[0009] (3) During the use of the belt transmission mechanism of the gluing machine, the rubber skin is easy to fall to the ground, and the transmission belt is easy to deviate;

[0010] (4) When the glue applicator is working, the glue is easy to overflow from both ends of the rubber roller
