Description

Technical Field

[0001] The utility model belongs to the technical field of coating devices, and in particular relates to a rubber roller gap adjustment component used in coating devices. Background Art

[0002] Coating is to attach one or more layers of materials with specific functions to the surface of the substrate to improve the surface function of the substrate or protect the substrate and enhance the utilization value of the substrate. There are many coating methods, and reverse roll coating is one of the most precise ones. A coater is a device for coating a substrate, and an existing coater includes a scraper and a coating roller, with a coating gap between the scraper and the coating roller. The thickness of the coating on the substrate can be adjusted by changing the size of the coating gap.

[0003] At present, the coating machine generally adjusts the size of the coating gap manually. However, during the coating process, the coating gap will change due to the accumulated error of equipment operation, vibration and other reasons.

The operation during adjustment is cumbersome and the adjustment precision error is large, which easily leads to poor consistency of coating thickness and surface density. Therefore, the utility model proposes a new solution. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figures 1 to 6 As shown, the embodiment of the utility model provides a rubber roller gap adjustment component applied to a coating device, comprising:

[0033] The laminating machine wall panels 3 are relatively placed to form a cavity 31 in the middle;

[0034] A glue-coated steel roller assembly 4, wherein the glue-coated steel roller assembly 4 is rotatably connected in the cavity 31;

[0035] A sliding component 22, the sliding component 22 is connected to the inner side of the laminating machine wall panel 3;

[0036] The metering rubber roller rotating assembly 1 is relatively installed on one side of the glue-coated steel roller assembly 4, so that a coating gap 133 is surrounded by the metering rubber roller rotating assembly 1 and the glue-coated steel roller assembly 4, and the metering rubber roller rotating assembly 1 is rotatably connected to the sliding assembly 22.

[0037] The adjusting component 21 is connected to the inner side of the laminating machine wall panel 3. The adjusting component 21 is connected to the sliding component 22 to control the sliding of the sliding component 22. The sliding component 22 can drive the metering rubber roller rotating component 1 to move relative to the glue coating steel roller component 4 to adjust the coating gap 133.

[0038] Specifically, the adjustment component 21 includes a support fixing plate 231, a reducer 211, a support fixing block 235, a support support block 233, a rotating rod 234, and a film pressing rubber roller fixing seat 232. The support fixing plate 231 is fixedly connected to the inner side of the laminating machine wall panel 3. The reducer 211, the support fixing block 235, the support support block 233 and the film pressing rubber roller fixing seat 232 are detachably connected to the support fixing plate 231. The design of adding a support fixing plate 231 to the bottom can make the connection of each component on the same axis, so as to improve the reliability, stability and efficiency of the adjustment component 21, and can better play the adjustment function.

[0042] Furthermore, the glue-coated steel roller assembly 4 is detachably mounted on the second rotating shaft hole 326 through the glue-coated steel roller pressing plate 321. Such a design enables the glue-coated steel roller pressing plate 321 to be better detachably mounted on the laminating machine wall panel 3.

[0043] Specifically, the sliding component 22 is symmetrically arranged on the inner side of the left laminating machine wall panel 32 and the right laminating machine wall panel 33, and the sliding component includes a metering rubber roller sliding fixed seat 223, a linear guide rail 222, and a guide rail block 221.

The lower end of the guide rail block 221 is slidably connected to the linear guide rail 222. Such a design can make the bearing stability and sliding effect of the sliding component 22 better.

[0044] Furthermore, a slide groove 2211 is provided at the bottom of the guide block 221, and the two linear guide rails 222 are installed relatively to each other as a group. A group of linear guide rails 222 is installed on the inner side of each of the left laminating machine wall panel 32 and the right laminating machine wall panel 33. The linear guide rails 222 can be inserted into the slide groove 2211. Such a design can make the guide block 221 easier to disassemble and install on the linear guide rails 222.

[0045] In addition, the metering rubber roller rotating assembly 1 is rotatably connected to the metering rubber roller sliding fixed seat 223, so that the metering rubber roller sliding fixed seat 223 can be driven to move by adjusting the rotation of the reducer 211, thereby driving the metering rubber roller rotating assembly 1 installed on the metering rubber roller sliding fixed seat 223, thereby smoothly adjusting the coating gap 133.

The connecting rod 131 is fixedly connected to the laminating machine wall panel 3, and the glue blocking scraper fixing plates 132 are relatively installed on the connecting rod 131 in groups of two. The glue blocking scraper fixing plates 132 can adjust the width and thickness of the glue coating to be uniform and can rotate and slide relative to the connecting rod 131. Such a design can make the gluing range wider and the gluing effect better.
