AI Technical Summary
Existing paper drying cylinder degumming equipment requires stopping the drying cylinder operation when cleaning the collection box, which reduces production and degumming efficiency, and the degumming effect is poor, failing to effectively solve the problem of adhesive accumulation on the surface of the drying cylinder.
A paper drying cylinder degumming device was designed, comprising a base, a rotating roller, a collection box, a filter screen, and a drive mechanism. The device achieves continuous degumming by having a scraper contact the adhesive on the surface of the drying cylinder and adjusting the distance between the scraper and the drying cylinder using a motor-driven screw. The adhesive is then collected through the glue inlet and the collection box.
It enables efficient scraping of adhesive residue during continuous operation of the drying cylinder, improving adhesive removal efficiency and production efficiency, simplifying the cleaning process, and avoiding downtime.

Technical Field
[0001] This utility model relates to the field of papermaking technology, and more specifically, to a paper drying cylinder degumming device. Background Technology
[0002] In papermaking, the raw waste paper contains a lot of adhesives, which cannot be completely removed by various pulping deslagging equipment. After the paper enters the drying section of the paper machine, these adhesives easily deposit on the surface of the drying cylinder. When the adhesives accumulate to a certain extent, they will seriously affect production, causing more paper defects and paper breaks. This is a difficult problem to solve in packaging paper production. Therefore, it is necessary to remove adhesives from the surface of the drying cylinder.
[0003] Existing paper drying cylinder degumming equipment requires stopping the drying cylinder during the cleaning of the collection box, which reduces production and degumming efficiency and results in poor degumming effect. Therefore, we propose a paper drying cylinder degumming equipment. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example
[0020] Please refer to the accompanying drawings. In this embodiment of the invention, the paper drying cylinder degumming device includes a base 1, with a glue inlet 7 at the top. Two support plates 3 are fixedly installed on both sides of the glue inlet 7 at the top of the base 1. Mounting plates 4 are rotatably mounted on the inner sides of the two support plates 4. A drying cylinder 6 is arranged between the two mounting plates 4. Rotary rollers 2 are installed at both ends of the drying cylinder 6. The two rotary rollers 2 pass through the two support plates 3 and are rotatably connected to the support plates 3. An opening 8 is provided on the side of the base 1. The opening 8 communicates with the glue inlet 7. Two collection boxes 9 are slidably arranged inside the opening 8. The collection boxes 9 are located directly below the glue inlet 7. A filter screen 10 is detachably installed in the middle of the two collection boxes 9. A degumming mechanism is provided at the top of the base 1 and below the rotary rollers 2. The system includes a movable groove 17; a drive mechanism is installed inside the movable groove 17; the adhesive removal mechanism includes two opposing mounting blocks 13; one side of each mounting block 13 has an oblique arc shape; a connecting strip 14 is detachably installed on the lower part of the arc surface of each mounting block 13; a triangular scraper 15 is provided at the outer end of each connecting strip 14; several through holes 16 are provided on the connecting strip 14; the drive mechanism includes a screw 11 rotatably mounted in the movable groove 17 via a rotating shaft; threaded sleeve rods 12 are threaded onto both sides of the screw 11; the top ends of the two threaded sleeve rods 12 are fixedly connected to the two mounting blocks 13 respectively; a motor 18 is installed on the outer side of the base 1; the output end of the motor 18 is connected to the screw 11 for transmission; several evenly distributed limiting rods 5 are fixedly connected to the inner side of the mounting plate 3. One end of the limiting rod 5 is fixedly connected to the inner side of another mounting plate 3. The movable groove 17 is U-shaped, and the two threaded rods 12 move horizontally within the movable groove 17. The bottom end of the threaded rod 12 is provided with a slider, and the bottom end of the movable groove 17 is provided with a sliding groove, and the slider slides in the sliding groove. The outer walls of the screw 11 are respectively provided with left and right threads. The lower ends of the two threaded rods 12 are respectively threaded to the left and right threads. Locking casters are fixedly connected to the four corners of the bottom surface of the base 1.
[0021] Usage process:
[0022] In use, the motor 18 is started, which drives the screw 11 to rotate. This causes the screw 11 to move the screw sleeves 12 on both sides relative to each other, thus adjusting the distance between the scraper 15 and the drying cylinder 6. When the drying cylinder 6 rotates, the adhesive on the surface of the drying cylinder 6 comes into contact with the scraper 15, thereby scraping off the adhesive on the surface of the drying cylinder 6. The scraped adhesive enters the glue inlet 7 through the through hole 16. The glue falls through the glue inlet 7 onto the filter screen 10 on the collection box 9 for collection. The two drawers are set up one above the other. When the upper collection box 9 is full, it can be pulled out, and the glue falls into the lower collection box 9. The glue can be cleaned without stopping the rotation of the drying cylinder 6. The glue is removed by the two scrapers 15 at the same time, which improves the glue removal effect.
[0023] In the above process, through the setting of the glue removal mechanism and the drive mechanism, the two mounting blocks move simultaneously to adjust the position of the scraper and the drying cylinder, which facilitates the adjustment of the distance between the scraper and the drying cylinder. The two scrapers scrape the glue simultaneously, improving the glue removal efficiency and effect. The setting of the glue inlet, the outlet, the collection box, and the filter screen makes it easier to collect the glue, and the drying cylinder does not need to be stopped when cleaning the glue inside the collection box, thereby improving production and glue removal efficiency. This application has a simple structure, strong practicality, and simple operation, and is worth promoting.
[0024] 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 concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
