Description

Technical Field

[0001] This invention is an online coated cream tissue paper roll production line, belonging to the field of roll-up devices. Background Technology

[0002] Cream-coated paper towels are a type of functional paper towel with added cream ingredients. They possess core characteristics such as softness, skin-friendliness, and moisturizing properties, and are increasingly widely used in daily life. Their production process typically employs a roller coating process, where the cream liquid is first evenly coated onto the surface of a roller, and then the cream liquid is transferred and adhered to the paper towel surface through contact between the roller and the substrate paper towel.

[0003] However, in the existing coating process of cream tissue production, the feeding speed is limited by coating quality control. If the feeding speed is too fast, the cream coating is prone to defects such as ripples and uneven thickness, resulting in substandard product surface smoothness. Therefore, existing production lines need to maintain a low feeding speed. To address this, the present invention aims to provide a high-speed online coating production line for cream tissues, which can significantly improve production efficiency while ensuring coating uniformity and core product quality.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0035] In existing cream tissue paper production coating processes, the feeding speed is limited by coating quality control. If the feeding speed is too fast, defects such as ripples and uneven thickness in the cream coating are prone to occur, resulting in substandard product surface smoothness. Therefore, existing production lines need to maintain a low feeding speed. To address this, the present invention aims to provide a high-speed online coating production line for cream tissue paper, significantly improving production efficiency while ensuring coating uniformity and core product quality. Therefore, to solve the above problems, this invention proposes the following technical solution:

[0036] Please see Figures 1 to 7This invention provides a technical solution for an online coated cream tissue paper roll production line: its structure includes: a material rack 1, conveyor rollers 3 adjacent to the material rack 1, a coating roller assembly 2 installed inside the conveyor rollers 3, a drying chamber 4 and a slitting chamber 5 connected sequentially to the conveyor rollers 3, a packaging chamber 6 connected to the slitting chamber 5 via a conveying mechanism, a conveyor belt 7 installed at the outlet of the packaging chamber 6, and a collection chamber 8 connected to the packaging chamber 6 via the conveyor belt 7; the coating roller assembly 2 includes a supporting shell 21, supporting outer frames 24 on both sides of the supporting shell 21, a cooling roller 22 and a coating roller 23 arranged between the supporting outer frames 24, a feeding hopper 26 installed on the surface of the coating roller 23, and a control roller 25 installed at the outlet of the feeding hopper 26; the feeding hopper 2... 6. The thickness of the emulsion coating roller 23 is controlled by the control roller 25. The cooling roller 22 includes a roller body 221 and a linkage box 222. The linkage box 222 is connected to the roller body 221 and the coating roller 23 respectively. The linkage box 222 is driven by the driver 223. The driver 223 drives the roller body 221 and the coating roller 23 to rotate synchronously through the linkage box 222. The roller body 221 is equipped with a temperature control component 211. The semiconductor heating strip 113 of the temperature control component 211 controls the first temperature-conducting end 112 and the second temperature-conducting end 114 at different temperatures. The first temperature-conducting end 112 is located at the top and is adjacent to the coating roller 23 and the discharge point of the roller body 221. The second temperature-conducting end 114 is located at the bottom.

[0037] The equipment in this production line is as follows: material rack 1 is used to place the substrate. Uncoated paper towels are placed on material rack 1 and coated by coating roller group 2 and conveyor roller 3.

[0038] After coating, the paper towels are dried in drying chamber 4 to fix the surface coating. Then, they are cut in slitting chamber 5 to the required length and then enter the packaging chamber 6 for packaging. After packaging, they are transported to the collection chamber 8 by conveyor belt 7. Finally, the paper towels are manually packed to complete the online coating process, which improves production efficiency.

[0039] The coating roller assembly 2 includes a feed hopper 26 for placing the cream liquid. After placement, the thickness of the coating on the surface of the coating roller 23 is controlled by the control roller 25. Specifically, a control motor is provided on one side of the control roller 25. The motor can be remotely controlled online. The gap between the control roller 25 and the coating roller 23 is controlled by rotating the control roller 25. The surface of the control roller 25 is provided with an arc surface. During the rotation, different gaps between the control roller 25 and the coating roller 23 can be controlled, thereby changing the thickness of the coating.

[0040] A cooling roller 22 is provided opposite to the coating roller 23. The cooling roller 22 and the coating roller 23 work together to hold the paper towel for coating. The cooling roller 22 and the coating roller 23 are installed inside the support shell 21 through the support frame 24. The shielding of the support shell 21 can reduce the impact of dust on the coating surface.

[0041] The cooling roller 22 drives the linkage box 222 through the side driver 223. The linkage box 222 drives the roller body 221 to rotate synchronously with the coating roller 23, avoiding unevenness caused by surface speed difference during coating.

[0042] The linkage box 222 meshes with the toothed ring 215 set on one side of the outer ring 212 of the roller body 221. One side of the roller body 221 is nested with the positioning plate 134 and the other side is nested with the main shaft of the support frame 24. The temperature control component 211 is installed on the inner wall of the outer ring 212 and slides with the outer ring 212, which can make the outer ring 212 more stable when rotating. The cream raw material has good fluidity at 35-50°C. At low temperature, the texture is thick or even solidifies, and it cannot be evenly transferred to the paper surface. Therefore, heating is required during the production of transfer printing. However, once the feeding speed is increased after heating and coating, the coating will deform and the surface will become uneven.

[0043] Therefore, this device is equipped with dual temperature zones to improve processing speed. Specifically, the temperature control component 211 is equipped with dual temperature zones that contact the outer ring 212. The top is a low temperature zone and the bottom is a high temperature zone. The bottom is connected to the heat-conducting arm 213 for heat conduction, which heats the heat-conducting roller 214 and can preheat the paper towel, making it easier for the coating to adhere during the transfer process.

[0044] The first temperature-conducting end 112 and the second temperature-conducting end 114 of the temperature control component 211 form a dual-temperature zone. The source of temperature is the semiconductor heating strip 113. The semiconductor heating strip 113 adopts a semiconductor cooling chip structure, with a cooling section at the top. It cools the coated cream paper by rapid cooling, so that the cream liquid can be quickly shaped. Then it is dried in the drying chamber 4 to remove the internal moisture and make it completely solidified.

[0045] The first temperature-conducting end 112 and the second temperature-conducting end 114 are fixed by bolts. The second temperature-conducting end 114 and the first temperature-conducting end 112 are separated by a semiconductor heating strip 113. A main shaft 111 is provided in the middle. A ceramic sleeve is provided on the surface of the main shaft 111 for heat insulation. A slot 115 is provided on the surface of the second temperature-conducting end 114. The heat-conducting arm 213 is connected through the slot 115 for heat conduction. Heat-conducting rollers 214 are installed between the heat-conducting arms 213 for heat conduction. The heat-conducting rollers 214 are used to adhere to the raw material paper towel.

[0046] The heat-conducting arm 213 includes an arm body 131, on which a connecting groove 132 is formed. This connecting groove 132 is nested and engaged with the main shaft 111 and the main shaft of the heat-conducting roller 214. The arm body 131 is made of metal. A heat-conducting column 133 is provided on the side of the arm body 131 opposite to the temperature control component 211. The heat-conducting column 133 is nested and engaged with the slots 115 on both sides of the second temperature-conducting end 114 to form a heat conduction path. A positioning plate 134 is also provided on the same side of the arm body 131 opposite to the temperature control component 211. The positioning plate 134 is fixedly connected to the main shaft 111, and the outer ring 212 is movably connected to the ring plate 135 extending from the positioning plate 134. The positioning plate 134 forms a semi-enclosed space, providing protection for the first temperature-conducting end 112 and the second temperature-conducting end 114.

[0047] In practical applications, the first temperature-conducting end 112 at the top, due to the lower temperature at the cooling center, can easily cause a sudden decrease in fluidity during the coating process if it is too close to the coating front end, affecting the coating effect. Therefore, the first temperature-conducting end 112 of this device is provided with a substrate 121, and an adjustable heat-conducting arc plate 122 is provided on the top of the substrate 121. The surface of the heat-conducting arc plate 122 has a positioning hole, and an adjusting bolt 123 is installed in the positioning hole. By locking the adjusting bolt 123, the heat-conducting arc plate 122 is limited, realizing the position adjustment of the heat-conducting arc plate 122 relative to the substrate 121, thereby changing the direct contact range and adjusting the temperature change in the low-temperature region. The cooling end of the semiconductor heating strip 113 is attached to the heat-conducting arc plate 122, and the heating end is attached to the second temperature-conducting end 114, forming a heat transfer circuit. The surface of the substrate 121 attached to the outer ring 212 is smaller than the surface of the second temperature-conducting end 114 attached to the outer ring 212 to ensure the uniformity of heat transfer.

[0048] The cooperation between the heat-conducting column 133 and the slot 115, as well as the nesting of the semiconductor heating strip 113 and the slot 115, achieves multiple heat conduction. This not only effectively utilizes the heat generated during the semiconductor cooling process but also prevents excessive temperature and ensures a smoother temperature transition. When the roller 221 rotates, the first temperature-conducting end 112 and the second temperature-conducting end 114 remain fixed, ensuring that the low-temperature zone is always at the top. This allows for rapid cooling and shaping of the cream after coating, reducing the fluidity of the cream. Consequently, while increasing the overall coating and conveying speed, it avoids uneven coating caused by acceleration. Furthermore, the adjustable position of the heat-conducting arc plate 122 of the first temperature-conducting end 112 allows for adjustment of the temperature variation range of the low-temperature zone according to actual needs. This prevents the fluidity of the coating front end from being affected by excessively low cooling center temperature, ensuring the stability of the coating process and the shaping effect.

[0049] The improved device provides precise control over coating thickness. The gap between the remotely controllable control roller 25 and the coating roller 23 can be adjusted. Combined with the arc-shaped structure of the control roller 25, the thickness of the cream coating can be flexibly adjusted to meet the needs of different products.

[0050] The cooling roller 22 and the coating roller 23 rotate synchronously through the linkage box 222, which completely avoids uneven coating thickness caused by differential speed, ensuring the consistency of the coating on the paper towel surface. The supporting shell 21 forms a closed space, effectively reducing dust contamination of the uncured coating. The rapid cooling function of the semiconductor heating strip 113 allows the cream liquid to be immediately set after coating, and then further cured by the drying chamber 4. The temperature control component 211 slides with the outer ring 212, improving the smoothness of the roller body 221 and extending the service life of the equipment.
