Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper tube base paper production technology, specifically to a starch spraying device between paper tube base paper layers. Background Technology
[0002] In the production process of paper tube base paper, starch spraying is an important step. The base paper typically requires interlayer spraying of starch solution to enhance the paper's strength and toughness, thereby improving the quality and stability of the paper tube.
[0003] However, existing starch spraying devices between the base paper layers of paper tubes have some shortcomings. Traditional spraying methods often use static mixing tanks or agitators, which easily leads to the deposition of starch and other materials at the bottom, resulting in uneven mixing and affecting the spraying effect. Moreover, because the materials deposited at the bottom are difficult to stir fully, local concentrations can easily become too high or too low, further affecting the quality of the paper tubes.
[0004] Therefore, this solution proposes a starch spraying device between the layers of paper tube base paper to solve the above problems. Utility Model Content
[0005] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a starch spraying device between the layers of paper tube base paper.
[0006] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows: A starch spraying device between layers of paper tube base paper includes a U-shaped support. Side fixing seats are installed on the inner sides of the left and right protruding ends of the U-shaped support. A horizontally distributed mixing roller is installed between the two side fixing seats. A rolling drive component that drives the mixing roller to roll is installed on the top of the U-shaped support. A mixing mechanism distributed inside the mixing roller is installed between the two side fixing seats. The mixing mechanism includes a horizontal support installed between the two side fixing seats and several mixing components installed sequentially from left to right on the horizontal support. A suction pipe located near the bottom inside the mixing roller is installed between the two side fixing seats. The right end of the suction pipe leads to the outside of the side fixing seat and is connected to a suction pump. The outlet end of the suction pump is connected to a spray pipe.
[0007] Preferably, the rolling drive component includes a geared motor, a drive gear, a transmission gear ring, and a synchronous shaft. There are two geared motors respectively mounted on the top center of the two side fixed seats. There are two drive gears respectively connected to the output ends of the two geared motors. There are two transmission gear rings respectively mounted at both ends of the mixing drum. The two transmission gear rings and the two drive gears mesh with each other. The synchronous shaft is connected to the center of the two drive gears.
[0008] Preferably, mounting bearings for positioning the ends of the mixing drum are installed on the inner end faces of the side fixing seats on both sides.
[0009] Preferably, a scraper is also installed between the side fixing seats on both sides, and the scraper is specifically distributed on the front side of the mixing drum and attached to its inner wall.
[0010] Preferably, the mixing assembly includes a drive motor mounted on a transverse support, a mixing shaft connected to the output end of the drive motor, and an upper spiral mixing blade, a lower spiral mixing blade, and a mixing rod mounted on the mixing shaft.
[0011] Preferably, the upper and lower spiral mixing blades are installed at the upper and lower ends of the mixing shaft respectively, the upper and lower spiral mixing blades have opposite thread directions, and the mixing rods are installed at multiple corresponding central positions on the mixing shaft.
[0012] Preferably, a feed pipe and a drain valve pipe leading to the inside of the mixing drum are installed on the left-side side fixing seat.
[0013] The beneficial effects of this utility model are reflected in:
[0014] This device uses a rolling drive to rotate the mixing drum. During this rotation, materials such as starch are constantly tumbled. Compared to traditional static mixing methods, rolling mixing allows the materials to move freely within the mixing drum, preventing starch and other materials from accumulating and settling at the bottom for extended periods. This is because the rolling motion keeps the materials in a dynamic state, ensuring thorough mixing and stirring in all areas, effectively preventing bottom sedimentation.
[0015] The scraper installed on the front side of the mixing drum further enhances the effect of preventing bottom sedimentation. The scraper adheres to the inner wall of the mixing drum, promptly scraping off any starch or other substances that may be adhering to the inner wall, preventing these substances from accumulating at the bottom. As the mixing drum rotates, the scraper continuously scrapes the inner wall, ensuring that the material throughout the mixing drum maintains good flowability, further improving the uniformity of mixing and avoiding uneven mixing problems caused by bottom sedimentation.
[0016] In summary, this interlayer starch spraying device for paper tubes, employing a rolling mixing process, not only effectively prevents starch mixture deposition at the bottom, ensuring uniform mixing, but also further enhances the stability and reliability of the mixing effect through the assistance of a scraper. This design allows starch and other materials to maintain a good state throughout the mixing process, providing a high-quality mixture for subsequent spraying operations. This improves the efficiency and quality of interlayer starch spraying on paper tubes, significantly contributing to the advancement of paper tube production processes. It reduces quality problems that may arise from bottom deposition, such as uneven mixing and localized concentration differences, laying a solid foundation for producing high-quality paper tube products. Furthermore, the rolling mixing method is relatively efficient and energy-saving, meeting the needs of large-scale production and possessing broad application prospects in the paper tube manufacturing industry.

[0035] The device mainly consists of a U-shaped support 1, a side fixed seat 2, a rolling drive component 3, a mixing drum 4, a mixing mechanism 5, a liquid extraction pipe 6, a liquid extraction pump 7, and a spray pipe 8.
[0036] Side fixing seats 2 are installed on the inner side of the left and right protruding ends of the U-shaped support 1. A mounting bearing 21 is installed on the inner end face of the side fixing seat 2 to position the end of the mixing drum 4, so that the mixing drum 4 can rotate freely between the side fixing seats 2.
[0037] The rolling drive component 3 includes two geared motors 31, a drive gear 32, a transmission gear ring 33, and a synchronous shaft 34. The two geared motors 31 are respectively mounted on the top center of the two side fixed seats 2. The drive gear 32 is connected to the output end of the geared motor 31. The transmission gear ring 33 is mounted at both ends of the mixing drum 4. The two transmission gear rings 33 and the two drive gears 32 are meshed with each other. The synchronous shaft 34 is connected to the center of the two drive gears 32. When the geared motors 31 are started, the mixing drum 4 can be driven to roll through the drive gear 32 and the transmission gear ring 33.
[0038] A horizontally distributed mixing drum 4 is installed between the side fixing seats 2 on both sides. A scraper 41 is installed on the front side of the mixing drum 4. The scraper 41 is attached to the inner wall of the mixing drum 4 and can scrape off starch and other substances on the inner wall of the mixing drum 4.
[0039] The mixing mechanism 5 includes a transverse support 51 installed between two side fixed seats 2, and several mixing components 52 sequentially installed on the transverse support 51 from left to right. Each mixing component 52 includes a drive motor 525 installed on the transverse support 51, and a mixing shaft 521 connected to the output end of the drive motor 525. The upper and lower ends of the mixing shaft 521 are equipped with upper spiral mixing blades 522 and lower spiral mixing blades 523 with opposite thread directions. Multiple mixing rods 524 are installed at the center of the mixing shaft 521. Starting the drive motor 525 rotates the mixing shaft 521, and the upper spiral mixing blades 522 and lower spiral mixing blades 523, along with the mixing rods 524, work together to thoroughly mix the starch and other materials inside the mixing drum 4.
[0040] A liquid extraction pipe 6 is installed between the two side fixing seats 2, located near the bottom inside the mixing drum 4. The right end of the liquid extraction pipe 6 leads to the outside of the side fixing seat 2 and is connected to a liquid extraction pump 7. The outlet end of the liquid extraction pump 7 is connected to a spray pipe 8.
[0041] The left-side fixed seat 2 is equipped with a feed pipe 9 and a drain valve pipe 10 that lead to the inside of the mixing drum 4. Starch and other materials can be added into the mixing drum 4 through the feed pipe 9 and discharged through the drain valve pipe 10 after mixing.
[0042] Working principle
[0043] Place the paper tubes that need to be sprayed with starch in a suitable position, ready to start the work.
[0044] Starch and other materials are added into the mixing drum 4 through the feed pipe 9 on the left side fixed seat 2.
[0045] Start the two geared motors 31. The output end of the geared motors 31 drives the drive gear 32 to rotate. The drive gear 32 meshes with the transmission gear ring 33, thereby driving the mixing drum 4 to roll between the side fixed seats 2.
[0046] As the mixing drum 4 rolls, the scraper 41 on its inner front side scrapes off the starch and other substances adhering to the inner wall of the mixing drum 4, so as to avoid them affecting the subsequent mixing effect.
[0047] Start each drive motor 525 installed on the horizontal support 51. The drive motor 525 drives the mixing shaft 521 to rotate. The upper spiral mixing blade 522 and the lower spiral mixing blade 523 on the mixing shaft 521, as well as the mixing rod 524, work together to fully mix the starch and other materials in the mixing drum 4, so that they are evenly distributed.
[0048] During the mixing process, the starch mixture near the bottom of the mixing drum 4 is drawn out through the extraction pipe 6, and the extraction pump 7 connected to the right end of the extraction pipe 6 draws out the mixture. The spray pipe 8 connected to the outlet end of the extraction pump 7 sprays the mixture onto the interlayer of the paper tube base paper.
[0049] After the spraying operation is completed, open the drain valve pipe 10 to discharge the mixed material from the mixing drum 4.
