Description

Technical Field

[0001] This utility model relates to an important component of corrugated base paper production equipment, and in particular to a double-sided glue spraying mechanism for corrugated base paper. Background Technology

[0002] In the production of corrugated paper, to meet the requirements of strength and toughness, both sides of the paper need to be coated with adhesive during processing. Many paper adhesive spraying devices are available on the market, but they can only spray adhesive on one side at a time, resulting in low efficiency. For example, a corrugated paper adhesive spraying device disclosed in application number 201820980226.6 sprays adhesive downwards onto the corrugated paper through a spray head, applying adhesive to only one side. Another example is a corrugated paper coating assembly disclosed in application number 202223136133.0, which also sprays adhesive downwards onto the upper surface of the corrugated paper through a spray head. Utility Model Content

[0003] The purpose of this utility model is to provide a double-sided adhesive spraying mechanism for corrugated paper base paper that can solve at least one of the above problems.

[0004] According to one aspect of the present invention, a double-sided glue spraying mechanism for corrugated paper base paper is provided, comprising a frame, a first glue supply pipe, a second glue supply pipe, a first roller, a second roller, a first glue spraying pipe, and a second glue spraying pipe. The first roller, the second roller, the first glue supply pipe, and the second glue supply pipe are all disposed on the frame. The upper end surface of the first roller is higher than the upper end surface of the second roller. The first roller and the second roller are correspondingly arranged. The first glue spraying pipe is connected to the first glue supply pipe, and the second glue spraying pipe is connected to the second glue supply pipe. The first glue spraying pipe is located above the first roller, and the second glue spraying pipe is located above the second roller.

[0005] The beneficial effects of this utility model are as follows: by providing a first roller and a second roller, it is convenient to clamp and convey the corrugated paper base paper, and the upper end surface of the first roller is higher than the upper end surface of the second roller, which facilitates the reservation of a position for the installation of the second glue spraying pipe; by providing a first glue spraying pipe and a second glue spraying pipe, glue can be sprayed on the first roller and the second roller respectively. Therefore, when the base paper is conveyed between the two rollers, glue treatment can be achieved on both sides of the corrugated paper base paper, thereby greatly improving the glue coating efficiency of the base paper, eliminating the need for multiple operations, and improving production efficiency.

[0006] In some embodiments, there are multiple first glue spray tubes arranged along the length of the first roller, and multiple second glue spray tubes arranged along the length of the second roller. This ensures that the glue sprayed from the respective glue spray tubes is evenly distributed on the respective rollers.

[0007] In some embodiments, the double-sided glue spraying mechanism for corrugated paperboard also includes a tension roller, which is mounted on a frame and located above the first and second rollers. Both the second roller and the tension roller are located on the same side of the first roller. Therefore, by setting the tension roller, the flatness of the paperboard conveyed between the first and second rollers can be ensured, facilitating uniform glue application to both sides of the paper.

[0008] In some embodiments, the frame is equipped with a mounting beam, which is inclined and has mounting blocks. The two ends of the mounting shaft of the tension roller are fitted onto the mounting blocks on the corresponding sides. Therefore, by inclining the mounting beam, the height of the tension roller can be easily adjusted, thereby facilitating the adjustment of the tension of the base paper.

[0009] In some embodiments, the mounting beam is provided with a groove, which is arranged along the length of the mounting beam, and the mounting block is mounted on the groove. Therefore, by providing a groove, the mounting beam can be easily moved along the groove to the corresponding position, facilitating adjustment.

[0010] In some embodiments, one end of the first glue-spraying tube is connected to the first glue-supplying tube, and the other end is bent downwards, corresponding to the first roller. One end of the second glue-spraying tube is connected to the second glue-supplying tube, and the other end is bent downwards, corresponding to the second roller. This facilitates the downward spraying of glue from each glue-spraying tube onto its respective roller. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings.

[0015] Reference Figures 1-3The double-sided glue spraying mechanism for corrugated paper base paper includes a frame 1, a first glue supply pipe 2, a second glue supply pipe 3, a first roller 4, a second roller 5, a first glue spraying pipe 6, and a second glue spraying pipe 7. The first roller 4, the second roller 5, the first glue supply pipe 2, and the second glue supply pipe 3 are all mounted on the frame 1. The upper end face of the first roller 4 is higher than the upper end face of the second roller 5. The first roller 4 and the second roller 5 are arranged correspondingly. The first glue spraying pipe 6 is connected to the first glue supply pipe 2, and the second glue spraying pipe 7 is connected to the second glue supply pipe 3. The first glue spraying pipe 6 is located above the first roller 4, and the second glue spraying pipe 7 is located above the second roller 5.

[0016] In actual use, the externally prepared glue is fed into the first glue supply pipe 2 and the second glue supply pipe 3, and then sprayed onto the first roller 4 via the first glue spray pipe 6 and onto the second roller 5 via the second glue spray pipe 7, so that the surfaces of the first roller 4 and the second roller 5 are both coated with glue. When the corrugated base paper is conveyed between the first roller 4 and the second roller 5, the first roller 4 and the second roller 5 clamp and convey the base paper, and the glue on the two rollers coats both sides of the base paper, thus achieving glue coating on both sides of the base paper.

[0017] Multiple first glue spray tubes 6 are arranged along the length of the first roller 4, and multiple second glue spray tubes 7 are arranged along the length of the second roller 5. This ensures that the glue sprayed downwards from the first glue spray tubes 6 is evenly distributed on the first roller 4; similarly, the glue sprayed downwards from the second glue spray tubes 7 is also evenly distributed on the second roller 5.

[0018] One end of the first glue spraying tube 6 is connected to the first glue supply tube 2, and the other end is bent downwards, corresponding to the first roller 4. That is, the glue sprayed downwards from the first glue supply tube 2 is sprayed onto the first roller 4. One end of the second glue spraying tube 7 is connected to the second glue supply tube 3, and the other end is bent downwards, corresponding to the second roller 5. That is, the glue sprayed downwards from the second glue supply tube 3 is sprayed onto the second roller 5.

[0019] The double-sided glue spraying mechanism for corrugated paper base paper of this utility model also includes a tension roller 8. The tension roller 8 is disposed on the frame 1 and located above the first roller 4 and the second roller 5. The second roller 5 and the tension roller 8 are both located on the same side of the first roller 4. By providing the tension roller 8, the conveyed corrugated paper base paper can be tensioned, so that the base paper can be conveyed flat between the first roller 4 and the second roller 5, which is conducive to the uniform glue application on both sides of the corrugated paper base paper.

[0020] A mounting beam 11 is welded and fixed on the frame 1. The mounting beam 11 is inclined and has mounting blocks 9 on it. The two ends of the mounting shaft of the tension roller 8 are sleeved on the mounting blocks 9 on the corresponding sides.

[0021] A groove 111 is provided on the mounting beam 11, and the groove 111 is set along the length of the mounting beam 11. The mounting block 9 is installed on the groove 111. Therefore, when the tension of the base paper needs to be adjusted, the height position of the tension roller 8 is adjusted. When the mounting block 9 slides upward along the groove 111, the distance between the tension roller 8 and the two rollers below it increases, making the base paper tighter; conversely, when the mounting block 9 moves downward, the distance between the tension roller 8 and the two rollers below it decreases, and the base paper is relatively looser.

[0022] The mounting block 9 and the slide groove 111 are fitted in a commonly used manner, that is, a screw is inserted into the mounting block 9, and a mating block is in the slide groove 111. The external screw passes through the mounting block 9 and engages with the mating block by thread, so that the mounting block 9 is clamped and fixed on the slide groove 111 by the mating block, thereby fixing the mounting block 9 at the corresponding position on the slide groove 111. When the position of the mounting block 9 needs to be adjusted, the screw is loosened to facilitate the adjustment of the mounting block 9.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
