Description

Technical Field

[0001] This utility model relates to the technical field of paper sizing temperature control devices, and in particular to a paper surface sizing temperature control device. Background Technology

[0002] In the papermaking process, sizing the paper surface is a key step in improving the paper's strength, water resistance, printability, and other properties.

[0003] In actual use, however, different types of paper have different requirements for the amount of surface sizing, and the sizing effect is affected by a variety of factors such as the temperature of the sizing solution and the feeding pressure. In the existing technology, manual adjustment or simple automatic control methods are often used, which makes it difficult to achieve precise control of the sizing temperature, resulting in poor sizing effect and affecting paper quality. This problem urgently needs to be improved, which makes it difficult to improve the surface sizing effect.

[0004] Therefore, to address the aforementioned problem of hindering the improvement of surface sizing effect, a paper surface sizing temperature control device can be designed. The temperature control layer inside the surface sizing tank, together with the condensate return water header, condensate supply water header, and TIC regulating valve, constitutes a temperature control system. Furthermore, the condensate water temperature from the steam condensate pump is approximately between 80 and 90 degrees Celsius, which precisely meets the sizing temperature control requirements. By using PID control regulating valve, the temperature drop of the sizing solution caused by sizing solution circulation can be effectively compensated, thereby achieving a stable sizing solution temperature and improving the surface sizing effect. Utility Model Content

[0005] In order to overcome the problem that traditional dyeing equipment often uses a single immersion or spraying method during the use of paper sizing temperature control devices, it is difficult to ensure the uniform distribution of dye in carpet fibers, especially when dealing with large-area or complex patterned carpets. This problem is particularly prominent and urgently needs to be improved, which in turn makes it difficult to improve the efficiency of uniform dyeing.

[0006] The technical solution of this utility model is as follows: a paper surface sizing temperature control device, comprising a support frame, a sizing roller, a surface sizing trough, a feeding pump, a feeding pipe, a PID control regulating valve, a spray pipe, a spray head, a condensate return water header, a condensate supply water header, a TIC regulating valve, a temperature control partition, a drive assembly, a collection assembly, a sieving assembly, and a stirring assembly; the drive assembly is installed inside the support frame, the sizing roller is installed on the side wall of the drive assembly, two sets of collection assemblies are installed below both ends of the sizing roller, and a sieving assembly is installed below the collection assemblies. The surface adhesive feeding tank is equipped with a stirring assembly inside.

A PID control regulating valve is installed on the side wall of the feeding pipe. A spray pipe is located at one end of the feeding pipe, and multiple spray heads are installed on the side wall of the spray pipe.

An internal stirring component continuously agitates the adhesive to ensure uniformity and prevent sedimentation. The adhesive is pressurized by a feeding pump and transported to the spray pipe via a feeding pipe. A PID control valve precisely regulates the adhesive flow rate in the feeding pipe, ensuring stable and accurate sizing. Multiple spray heads evenly distributed on the sidewall of the spray pipe spray the adhesive in a mist form onto the surface of the moving paper, achieving efficient sizing. In addition, the glue dripping from both ends of the glue application roller is collected by the collection components on both sides, and then conveyed to the inside of the screening component for screening and filtration. The filtered glue is then conveyed to the surface glue feeding tank for recycling. At the same time, the temperature control layer set in the surface glue feeding tank, together with the condensate return water header, condensate supply water header and TIC regulating valve, constitutes a temperature control system. The condensate water temperature from the steam condensate pump is about 80 to 90 degrees Celsius, which just meets the glue temperature control requirements. Through PID control of the regulating valve, the glue temperature drop caused by glue circulation can be well compensated, thereby achieving a stable glue temperature for feeding and improving the surface glue application effect.

[0024] Please see Figures 3-4In this embodiment, the screening assembly includes a screening chamber 301, a vibrating motor 302, and a fixed base 303. A collection pipe 202 is disposed below the collection chamber 201, and the screening chamber 301 is disposed at the lower end of the collection pipe 202. A fixed base 303 is disposed on the inner side wall of the screening chamber 301, and a vibrating motor 302 is disposed on the side wall of the fixed base 303. The adhesive flows into the screening chamber 301 through the collection pipe 202, and starting the vibrating motor 302 generates high-frequency vibration. The screening assembly also includes a connecting pipe 304, a vibrating circular screen 305, a fixing ring 306, and a connecting spring 307. A fixing ring 306 is disposed inside the screening chamber 301, and a connecting spring 307 is disposed above the fixing ring 306. Multiple sets of connecting springs 307 are provided.

[0025] When the paper sizing temperature control device is in use, starting the active motor 101 can drive the active wheel 103 to rotate via the active shaft 102.

[0029] Meanwhile, the temperature control layer 12 inside the surface adhesive loading tank 3, together with the condensate return water header 9, the condensate supply water header 10, and the TIC regulating valve 11, constitute a temperature control system. Furthermore, the condensate water temperature from the steam condensate pump is approximately between 80 and 90 degrees Celsius, which just meets the adhesive temperature control requirements. By using the PID control regulating valve 6, the temperature drop of the adhesive caused by the circulation of the adhesive can be well compensated, thereby achieving a stable loading adhesive temperature and improving the surface adhesive application effect.

[0030] Through the above steps, when the paper sizing temperature control device is in use, activating the drive component can simultaneously drive the two sets of sizing rollers 2 to rotate synchronously. The two sets of sizing rollers 2 enable paper conveying and surface sizing operations. During the sizing process, the surface adhesive feeding tank 3 serves as the core for adhesive storage and supply. Its internal stirring component continuously stirs the adhesive to ensure uniformity and prevent sedimentation. The adhesive is pressurized by the feeding pump 4 and conveyed to the spray pipe 7 via the feeding pipe 5. The PID control regulating valve 6 precisely controls the flow rate of the adhesive in the feeding pipe 5, ensuring stable and accurate sizing. Multiple spray heads 8 evenly distributed on the side wall of the spray pipe 7 spray the adhesive in a mist form onto the surface of the moving paper, achieving high efficiency. In addition to the application of adhesive, the adhesive dripping from both ends of the application roller 2 is collected by the collection components on both sides and then transported to the inside of the screening component for screening and filtration.
