Description

Technical Field

[0001] This application relates to the field of papermaking technology, specifically to a tissue paper processing system and its humidity control device. Background Technology

[0002] The post-processing production flow of facial tissues in the household paper industry is as follows: unwinding of raw paper → interlayer pressing (embossing / line pressing) → folding → slitting → individual packaging of paper blocks → inner bag packaging → finished product boxing.

[0003] In the unwinding step of the base paper, because tissue paper has a fibrous structure, the national standard for moisture content is 3%-10%. The lower the moisture content, the more brittle and hard the paper becomes. According to actual tests, when the moisture content of the base paper is <6%, the bonding strength after pressing the paper will decrease significantly, and the stability and pass rate of embossing will also decrease substantially. Due to various factors such as the fiber characteristics of the base paper raw material, papermaking process, storage time, and storage environment, the moisture content of the base paper is difficult to control in the past production process, which in turn affects the pressing quality. In the existing post-processing production technology of tissue paper, the process steps lack control over the moisture content of the base paper. Utility Model Content

[0004] In view of the above problems, this application provides a tissue paper processing system and its humidity control device to solve the problem that the existing post-processing production process of tissue paper lacks control over the moisture content of the raw paper, which leads to a decrease in bonding strength after paper pressing, and a decrease in the stability and quality of embossing.

[0064] Please see Figure 1 This embodiment provides a humidity control device for a tissue paper processing system, including:

[0065] Main water pipe 110, one end of which is connected to a spray water source;

[0066] The spray mechanism comprises several units, each corresponding to one of the unwinding frames 210 of the tissue paper processing system. Each spray mechanism includes a water spray pipe 122 and a spray nozzle 121. One end of the water spray pipe 122 is connected to the main water pipe 110, and the spray nozzle 121 is connected to the other end of the water spray pipe 122. The spray nozzle 121 is located on one side of the unwinding frame 210 and is used to humidify and spray the base paper 220 on the unwinding frame 210.

[0067] The spray mechanism is connected to the main water source via a main pipe. Each unwinding rack 210 in the tissue paper processing system is equipped with a corresponding spray mechanism. The spray nozzle 121 in the spray mechanism is connected to the main water pipe 110 via a water spray pipe 122. When it is necessary to humidify the raw paper 220 on each unwinding rack 210 in the tissue paper processing system, the spray nozzle 121 is turned on to humidify the raw paper 220 on the unwinding rack 210. This ensures that when the raw paper 220 is unwound from the unwinding rack 210 and enters the next pressing process, the moisture content of the raw paper 220 meets the requirements. This prevents the paper from losing bonding strength due to low moisture content after pressing, thereby improving the stability of pressing and increasing the pass rate.

[0068] like Figure 2 As shown, the spray nozzle 121 sprays water mist 130 onto the paper 220 on the unwinding frame 210, and the water mist 130 adheres to the paper, thereby increasing the moisture content of the paper 220.

[0069] In some embodiments, it also includes:

[0070] A solenoid valve is installed at the inlet end of the main water pipe 110.

[0071] In this embodiment, by installing a solenoid valve on the main water pipe 110, the connection and disconnection between the spray nozzle 121 connected to the same main water pipe 110 and the spray water source can be synchronously controlled, thereby controlling the spray humidification of the base paper 220 on the unwinding frame 210 by the spray nozzle 121. In other embodiments, a solenoid valve can also be installed on the spray pipe 122 of each spraying mechanism to realize the connection and disconnection between the spray nozzle 121 and the spray water source.

[0072] In some embodiments, it also includes:

[0073] A moisture meter is installed at the paper inlet end of the next process after the unwinding rack 210 of the tissue paper processing system, and the moisture meter is connected to the solenoid valve.

[0074] A moisture detector is installed at the paper inlet end of the unwinding process of the unwinding rack 210 in the tissue paper processing system to detect the moisture content of the raw paper 220 that is about to enter the pressing process. When the moisture content of the raw paper 220 entering the pressing process is found to be insufficient, the spray nozzle 121 and the spray water source are connected through the solenoid valve on the main water pipe 110 to spray and humidify the raw paper 220 on the unwinding rack 210.

[0075] Please see Figure 3 In some embodiments, the tissue paper processing system includes two sets of unwinding frames 210;

[0076] The main water pipe 110 includes a first main water pipe 111 and a second main water pipe 112;

[0077] The spray mechanism corresponding to the unwinding rack 210 of the first group of the tissue paper processing system is connected to the first main water pipe 111;

[0078] The spray mechanism corresponding to the unwinding rack 210 of the second group of the tissue paper processing system is connected to the second main water pipe 112;

[0079] The solenoid valve includes a first solenoid valve 141 and a second solenoid valve 142. The first solenoid valve 141 is disposed on the first main water pipe 111, and the second solenoid valve 142 is disposed on the second main water pipe 112.

[0080] The moisture detector includes a first moisture detector 151 and a second moisture detector 152. The first moisture detector 151 is located at the paper feed end of the next process of the unwinding frame 210 of the first group and is connected to a first solenoid valve 141. The second moisture detector 152 is located at the paper feed end of the next process of the unwinding frame 210 of the second group and is connected to a second solenoid valve 142.

[0081] In a typical tissue paper processing system, there are two sets of unwinding frames 210 to unwind and feed paper to the next pressing process. Therefore, a first main water pipe 111 and a second main water pipe 112 are respectively set up. The spray mechanism connected to the first main water pipe 111 corresponds one-to-one with the first set of unwinding frames 210, and the spray mechanism connected to the second main water pipe 112 corresponds one-to-one with the second set of unwinding frames 210. Two moisture detectors can be used to detect the moisture content of the base paper 220 fed into the next process by the two sets of unwinding frames 210, thereby controlling the operation of the spray mechanisms corresponding to the two sets of unwinding frames 210.

[0082] In some embodiments, the spray nozzle 121 is disposed on one side of the paper exit position of the unwinding frame 210. By distributing the spray nozzle 121 on one side of the paper exit position of the unwinding frame 210, the unwound paper 220 on the unwinding frame 210 is humidified, thus ensuring the moisture content of the paper 220.

[0083] In the post-processing production of household paper, a humidity control device and process are added to fill the process gaps and upgrade the process to: unwinding of raw paper → online moisture control of raw paper → interlayer pressing (embossing / line pressing) → folding → slitting → individual packaging of paper blocks → middle bag packaging → finished product boxing. The specific steps are: (1) establish a water supply pipeline and system, and the humidity control device provides the water source; (2) add a humidity spray device; (3) add an automatic detection device to automatically adjust the moisture.

[0086] Humidity control device, the humidity control device comprising:

[0087] Main water pipe 110, one end of which is connected to a spray water source;

[0088] The spray mechanism comprises several units, each corresponding to one of the unwinding frames 210 of the tissue paper processing system. Each spray mechanism includes a water spray pipe 122 and a spray nozzle 121.

The spray nozzle 121 is located on one side of the unwinding frame 210 and is used to humidify and spray the base paper 220 on the unwinding frame 210.

[0089] The spray mechanism is connected to the main water source via a main pipe. Each unwinding rack 210 in the tissue paper processing system is equipped with a corresponding spray mechanism. The spray nozzle 121 in the spray mechanism is connected to the main water pipe 110 via a water spray pipe 122. When it is necessary to humidify the raw paper 220 on each unwinding rack 210 in the tissue paper processing system, the spray nozzle 121 is turned on to humidify the raw paper 220 on the unwinding rack 210. This ensures that when the raw paper 220 is unwound from the unwinding rack 210 and enters the next pressing process, the moisture content of the raw paper 220 meets the requirements. This prevents the paper from losing bonding strength due to low moisture content after pressing, thereby improving the stability of pressing and increasing the pass rate.

[0090] like Figure 2 As shown, the spray nozzle 121 sprays water mist 130 onto the paper 220 on the unwinding frame 210, and the water mist 130 adheres to the paper, thereby increasing the moisture content of the paper 220.

[0091] In some embodiments, the humidity control device further includes:

[0092] A solenoid valve is installed at the inlet end of the main water pipe 110.

[0093] In this embodiment, by installing a solenoid valve on the main water pipe 110, the connection and disconnection between the spray nozzle 121 connected to the same main water pipe 110 and the spray water source can be synchronously controlled, thereby controlling the spray humidification of the base paper 220 on the unwinding frame 210 by the spray nozzle 121. In other embodiments, a solenoid valve can also be installed on the spray pipe 122 of each spraying mechanism to realize the connection and disconnection between the spray nozzle 121 and the spray water source.

[0094] In some embodiments, the humidity control device further includes:

[0095] A moisture meter is installed at the paper inlet end of the next process after the unwinding rack 210 of the tissue paper processing system, and the moisture meter is connected to the solenoid valve.

[0096] A moisture detector is installed at the paper inlet end of the unwinding process of the unwinding rack 210 in the tissue paper processing system to detect the moisture content of the raw paper 220 that is about to enter the pressing process. When the moisture content of the raw paper 220 entering the pressing process is found to be insufficient, the spray nozzle 121 and the spray water source are connected through the solenoid valve on the main water pipe 110 to spray and humidify the raw paper 220 on the unwinding rack 210.

[0097] Please see Figure 3 In some embodiments, the main water pipe 110 includes a first main water pipe 111 and a second main water pipe 112;

[0101] The moisture detector includes a first moisture detector 151 and a second moisture detector 152. The first moisture detector 151 is located at the paper feed end of the next process of the unwinding frame 210 of the first group and is connected to a first solenoid valve 141. The second moisture detector 152 is located at the paper feed end of the next process of the unwinding frame 210 of the second group and is connected to a second solenoid valve 142.

[0102] In a typical tissue paper processing system, there are two sets of unwinding frames 210 to unwind and feed paper to the next pressing process. Therefore, a first main water pipe 111 and a second main water pipe 112 are respectively set up. The spray mechanism connected to the first main water pipe 111 corresponds one-to-one with the first set of unwinding frames 210, and the spray mechanism connected to the second main water pipe 112 corresponds one-to-one with the second set of unwinding frames 210. Two moisture detectors can be used to detect the moisture content of the base paper 220 fed into the next process by the two sets of unwinding frames 210, thereby controlling the operation of the spray mechanisms corresponding to the two sets of unwinding frames 210.

[0103] In some embodiments, the spray nozzle 121 is disposed on one side of the paper exit position of the unwinding frame 210. By distributing the spray nozzle 121 on one side of the paper exit position of the unwinding frame 210, the unwound paper 220 on the unwinding frame 210 is humidified, thus ensuring the moisture content of the paper 220.
