Description

Technical Field

[0001] The utility model relates to the field of gluing, in particular to a novel ultra-thin uniform gluing device. Background Art

[0002] Gluing is widely used in industrial production, involving the uniform application of glue liquid onto the surface of a workpiece substrate. Currently, large-area planar workpieces are often coated with glue using a roller coating device. The coating thickness is controlled by the gap between the roller and the pressure roller, as well as the hardness of the rubber coating on the roller, to absorb the manufacturing errors of the roller and control the coating thickness. However, when applying ultra-thin coatings to workpiece surfaces, there are the following drawbacks: First, the thickness of the glue layer produced by the roller coating structure alone, which only passes through the relative gap, is relatively large, making it difficult to achieve the ultra-thin coating thickness required by the workpiece. Second, the output glue layer thickness of the roller coating structure is uneven, resulting in uneven coating thickness, which results in poor product yield. Therefore, a glue coating device that can achieve ultra-thin coatings and uniform roll coating is needed. Utility Model Content

A continuous spiral rubber coating groove is precisely machined on the outer wall of the rubber coating. The couplings on both sides of the core are connected to the frame through bearings.

[0006] The feeding pressure wheel is arranged on the left end of the rubber roller and the shafts at both ends are rotatably connected to the frame. The center distance between the feeding pressure wheel and the rubber roller is less than the sum of the radii of the two wheels, that is, the outer wall of the feeding pressure wheel squeezes and flattens the tooth tops of the rubber roller's coating grooves to make the groove depth at the connection uniform, and the material at the tooth top position deforms toward both sides of the tooth shape to make the groove depth at the connection shallower, thereby making the rubber coating groove at the connection uniform and ultra-thin;

Even on the original glue coating machine, ultra-thin and uniform glue coating can be achieved by simply replacing the roller coating wheel. New processes and new products can be processed with low modification costs and are easy to promote and apply.

[0009] In some embodiments, the pitch B of the glue coating groove is in the range of 0.01-0.1 mm, and the tooth angle A is in the range of 60°-120°.

[0014] In some embodiments, a transmission assembly is further included, the transmission assembly including an upper driving wheel, a lower driving wheel, a tensioning wheel, a driving wheel and an annular transmission member;

[0015] The upper driving wheel key sleeve is connected to a coupling shaft of the rubber roller;

As shown in the figure, the novel ultra-thin uniform glue coating device comprises: a rubber coating roller 1, a feeding pressure roller 2, and a support wheel 3;

[0035] The rubber roller 1 comprises a cylindrical steel core 10, preferably made of 0Cr18Ni9 stainless steel. The outer wall of the core 10 is evenly coated with a rubber coating 11, which is precision-machined into a continuous, spiral rubber coating groove 12. This groove 12 is free of cracks and burrs and has a uniform pitch. The pitch B of the spiral rubber coating groove 12 is preferably in the range of 0.01mm-0.1mm, and the thread angle A is preferably in the range of 60°-120°. The coupling shafts 13 on either side of the core 10 are rotatably connected to the frame 01 via bearings 14.

[0036] The feeding pressure wheel 2 is arranged on the left end of the rubber roller 1 and the shafts at both ends are rotatably connected to the frame 01. The center distance between the feeding pressure wheel 2 and the rubber roller 1 is less than the sum of the radii of the two wheels, that is, the outer wall of the feeding pressure wheel 2 squeezes and flattens the tooth tops of the rubber coating groove 12 of the rubber roller 1 so that the groove depth at the connection is uniform, and the material at the tooth top position is deformed to both sides of the tooth shape so that the groove depth at the connection becomes shallower, thereby making the rubber coating groove 12 at the connection uniform and ultra-thin;

[0037] The support wheel 3 is located directly below the rubber roller 1 and the shafts at both ends are rotatably connected to the frame 01. The workpiece enters between the support wheel 3 and the rubber roller 1. The rubber roller 1 is squeezed by the bottom of the glue coating groove 12 to evenly drive the glue liquid, so that a uniform ultra-thin glue layer is formed on the surface of the workpiece.

[0038] The outer wall of the rubber layer of this new ultra-thin uniform glue coating device has a continuous spiral groove; the outer wall of the feeding pressure wheel squeezes the groove on the surface of the roller coating wheel, and by squeezing and deforming the groove, the excess paint in the groove is squeezed out, and the unextruded paint will follow the rotation of the roller coating wheel and carry liquid, and the roller coating wheel applies the squeezed liquid to the surface of the processed product by rolling; the support wheel is located directly below the roller coating wheel, and the workpiece enters between the support wheel and the roller coating wheel, and then by adjusting the height of the roller coating wheel, the interference pressing amount of the roller coating wheel and the support wheel is controlled to form a uniform and ultra-thin glue layer on the surface of the workpiece.

[0039] The beneficial effects of the new ultra-thin uniform glue coating device are: first, the glue coating groove 12 is a spiral line, and the tooth top of the glue coating groove 12 is squeezed and flattened by the feeding pressure wheel 2, so that the gap between the two is controlled at a constant height within the tooth height at the same time, and the squeezed glue coating groove 12 forms an ultra-thin and equal-height glue-carrying channel, so that ultra-thin and uniform glue coating can be achieved, and the coating of the workpiece is ultra-thin and uniform; second, the structure is simple and easy to assemble and maintain. Even on the original glue coating machine, ultra-thin and uniform glue coating can be achieved by simply replacing the roller glue wheel 1. New processes and new products can be processed with low transformation costs and are easy to promote and apply.

[0040] Preferably, the tooth tops of the glue coating groove 12 are processed into sharp corners or rounded corners. The beneficial effect is that this setting helps to achieve a roller coating effect.

[0049] The annular transmission member 55 sequentially covers the driving wheel 54, the lower driving wheel 52, the upper driving wheel 51 and the tensioning wheel 53. The beneficial effect is that the transmission assembly 5 drives the rubber coating roller 1 and the support wheel 3 at the same time, and makes them rotate at the same speed and in opposite directions, with precise transmission and compact structure, which is beneficial to the uniformity of the rubber coating process.

[0051] The feed roller 2 and the rubber coating roller 1 move in opposite directions, forming a reverse coating mechanism; or the feed roller 2 and the rubber coating roller 1 move in the same direction, forming a co-directional coating mechanism. The beneficial effect is that the above arrangement can stably output rotational power, ensure stable rotation of the connected parts, and stabilize the coated product.

[0052] Furthermore, both ends of the feeding pressing wheel 2 are connected to the frame 01 through the distance adjustment and clamping assembly 02, so as to adjust the center distance between the feeding pressing wheel 2 and the rolling rubber coating wheel 1, and then adjust the depth of the rubber coating groove 12.

The guide portion 022's slide rail is fixedly connected to the frame 01, and the mounting block to which the threaded adjustment rod is threaded is fixedly connected to the frame 01. Rotating the threaded adjustment rod moves the feed roller 2. This arrangement facilitates controllable and reliable adjustment of the thickness of ultra-thin coatings.

[0054] Furthermore, height adjusters 6 are installed under the four supporting feet of the frame 01. Its beneficial effect is that this arrangement can provide a good roller coating reference plane, which is beneficial to achieving uniformity of the coating.
