Description

Technical Field

[0001] The utility model relates to the field of decorative paper dipping equipment, in particular to a decorative paper dipping paper web tension adjusting device. Background Technique

[0002] Decorative paper is an essential raw material in many building materials products, such as low-pressure boards and high-pressure boards used in furniture and cabinets, as well as fireproof boards, floors, etc. In the product structure, decorative paper is placed under the surface paper, mainly playing the role of providing decorative patterns and covering to prevent the bottom glue from seeping. This layer requires the paper to have good covering power, impregnation property, and printing performance. Decorative paper requires a smooth surface, good absorbency and adaptability, and a uniform color tone for the background color and bright colors for the colored ones. In the production and processing processes of surface treatment of decorative paper, such as coating and printing, the impregnation method is generally used to improve the strength of decorative paper, and the existing impregnation treatment generally uses an impregnation tank.

[0003] However, since the decorative paper needs to be immersed in the glue during the dipping process, some guide rollers also need to be synchronously immersed in the glue to ensure that the decorative paper is located below the liquid level of the glue. However, this structure also causes that when loading the decorative paper, it is necessary to temporarily empty the glue or lower the liquid level of the glue by a certain height to ensure that all guide rollers are exposed before the decorative paper can be loaded, which greatly affects the dipping efficiency of the decorative paper.

[0004] At the same time, it is usually difficult to adjust the tension of the decorative paper adaptively in the current decorative paper dipping equipment, and the loose decorative paper will cause uneven dipping during dipping. Content of the Utility Model

[0005] The purpose of the utility model is to provide a decorative paper dipping paper web tension adjusting device that improves the convenience of loading the decorative paper and can adjust the tension of the decorative paper during dipping to ensure the dipping uniformity of the decorative paper.

[0006] To solve the above technical problems, the utility model provides a decorative paper dipping paper web tension adjusting device, which includes a box body, an impregnation tank arranged at the bottom inside the box body, a feed port opened on one side of the box body, and a discharge port opened on the other side of the box body. A main support frame is liftably arranged at the top inside the box body. A first roller and a second roller are rotatably arranged at opposite ends of the main support frame. A sub-support frame is arranged below the main support frame. A first tensioning roller and a second tensioning roller are rotatably arranged at opposite ends of the sub-support frame. And there is a telescopic fit between the first tensioning roller and the sub-support frame and between the second tensioning roller and the sub-support frame, so that the decorative paper sequentially passes around the upper side of the first roller, the lower sides of the first tensioning roller and the second tensioning roller, and the upper side of the second roller.

[0007] Further, the end of the first tensioning roller is rotatably mounted on the first adjusting rod, the end of the second tensioning roller is rotatably mounted on the second adjusting rod, and both the first adjusting rod and the second adjusting rod are telescopically arranged on the auxiliary support frame.

[0008] Further, a telescopic rod is connected between the auxiliary support frame and the inner bottom of the box body, and the telescopic rod is communicated to the first adjusting rod and the second adjusting rod through a pipeline, so that when the telescopic rod contracts, the first adjusting rod and the second adjusting rod extend relative to the auxiliary support frame.

[0009] Further, a driving rod is rotatably arranged on the top of the box body, a guide rod is arranged on the side of the driving rod, and the main support frame is in threaded fit with the driving rod through a driving hole, and the main support frame is in moving fit with the guide rod through a guide hole.

[0010] Further, a connecting rod is connected between the main support frame and the auxiliary support frame.

[0011] Further, a plurality of limiting blocks are circumferentially distributed at the ends of the first roller and the second roller.

[0012] Further, a guiding assembly is arranged on the feeding port and the discharging port, and the guiding assembly includes at least two rotatably arranged guiding rollers.

[0013] Further, a liquid level prompt is arranged on the side of the inner part of the box body. When the auxiliary support frame rises to the loading position, the first tensioning roller and the second tensioning roller are located above the liquid level prompt. When the auxiliary support frame descends to the dipping position, the first tensioning roller and the second tensioning roller are located below the liquid level prompt.

[0014] Further, a warehouse door is detachably arranged on one side of the box body, and the warehouse door is arranged higher than the liquid level prompt.

[0015] Further, an observation window is arranged on the warehouse door.

[0016] The beneficial effects of the present utility model are as follows: When feeding the decorative paper, the main support frame rises to drive the auxiliary support frame to rise above the liquid level of the glue, so that the first tensioning roller and the second tensioning roller are separated from the glue. At this time, the decorative paper is extended into the inner side of the box body from the feeding port, so that the decorative paper sequentially winds around the upper side of the first roller, the lower sides of the first tensioning roller and the second tensioning roller, and the upper side of the second roller, and the decorative paper is extended out from the discharging port. And this feeding method can effectively avoid the situation of needing to empty the glue and reducing the liquid level of the glue, and improve the convenience of feeding the decorative paper.

[0017] After the decorative paper feeding is completed, the main support frame drives the auxiliary support frame to descend, so that the first tension roller and the second tension roller descend to the lower side of the liquid level of the glue solution, ensuring that the decorative paper can be immersed in the glue solution. At the same time, by extending the first tension roller and the second tension roller relative to the auxiliary support frame, the distance between the first tension roller and the second tension roller is increased, thereby increasing the total travel of the decorative paper between the rotating roller and the tension roller, facilitating the adjustment of the tension degree of the decorative paper, and ensuring that the decorative paper can be evenly impregnated with glue.

A sub-support frame 8 is arranged below the main support frame 5. A first tensioning roller 9 and a second tensioning roller 10 are rotatably arranged at opposite ends of the sub-support frame 8. And there is a telescopic fit between the first tensioning roller 9 and the sub-support frame 8, and between the second tensioning roller 10 and the sub-support frame 8, so that the decorative paper sequentially winds around the upper side of the first roller 6, the lower sides of the first tensioning roller 9 and the second tensioning roller 10, and the upper side of the second roller 7.

[0027] When feeding the decorative paper, the main support frame 5 rises to drive the sub-support frame 8 to rise above the liquid level of the glue, so that the first tensioning roller 9 and the second tensioning roller 10 are separated from the glue. At this time, the decorative paper is inserted into the inner side of the box body 1 from the feeding port 3, so that the decorative paper sequentially winds around the upper side of the first roller 6, the lower sides of the first tensioning roller 9 and the second tensioning roller 10, and the upper side of the second roller 7, and the decorative paper is extended from the discharging port 4. And this feeding method can effectively avoid the situation of needing to empty the glue and reducing the liquid level of the glue, improving the convenience of feeding the decorative paper.

[0028] After the feeding of the decorative paper is completed, the main support frame 5 drives the sub-support frame 8 to descend, so that the first tensioning roller 9 and the second tensioning roller 10 descend below the liquid level of the glue to ensure that the decorative paper can be immersed in the glue. At the same time, by extending the first tensioning roller 9 and the second tensioning roller 10 relative to the sub-support frame 8, the distance between the first tensioning roller 9 and the second tensioning roller 10 is increased, thereby increasing the total travel of the decorative paper between the rollers and the tensioning rollers, so as to facilitate adjusting the tension degree of the decorative paper and ensure that the decorative paper can be subjected to uniform dipping processing.

[0029] It is worth mentioning that the connection parts of the main support frame 5 with the first roller 6 and the second roller 7 are located at both ends of the first roller 6 and the second roller 7, and the connection parts of the sub-support frame 8 with the first tensioning roller 9 and the second tensioning roller 10 are located at both ends of the first tensioning roller 9 and the second tensioning roller 10 to avoid the moving path of the decorative paper.
