Description

Technical Field

[0001] This utility model relates to the field of regenerated cellulose membrane coating production technology, specifically to a curing and stabilization treatment device for multi-purpose coated regenerated cellulose membranes. Background Technology

[0002] In the production process of multi-purpose coated regenerated cellulose film, the coated film may experience discoloration, roll shifting, and wrinkling due to factors such as moisture content, curing speed, shrinkage, and temperature uniformity. In particular, after high-temperature drying during the coating process, the regenerated cellulose film may stick together or break. Furthermore, because the relevant indicators of the coated regenerated cellulose film do not meet the requirements of subsequent processing, folds, roll shifting, and film breakage are prone to occur during post-processing.

[0003] To ensure the coating quality and post-processing stability of multi-purpose coated regenerated cellulose membranes, the coated regenerated cellulose membranes need to be cured and stabilized under specific conditions.

[0004] Currently, the high-temperature ovens used in the production process can only control the temperature during the coating process of regenerated cellulose membranes. This results in problems such as large temperature control deviations and uneven drying. Furthermore, the control of other technical indicators must be carried out after the temperature control is completed, which is time-consuming, labor-intensive, and unstable, and is not conducive to improving production efficiency and quality.

[0005] In view of the problems existing in the prior art, this utility model combines years of design and use experience in related fields to design and manufacture a multi-purpose curing and stabilization treatment device for coated regenerated cellulose membranes, in order to overcome the above defects.

The ends of the several humidity regulating branch pipes away from the humidity regulating duct extend into the curing chamber. The several humidity regulating branch pipes are evenly disposed on the side wall of the curing chamber and communicate with the interior of the curing chamber.

[0013] The humidity control device also includes a dehumidifier, which is located close to the humidifier, and the output end of the dehumidifier is connected to the curing box through a dehumidification duct.

[0019] Preferably, several groups of paper-feeding assemblies are arranged sequentially up and down on the inner wall of the curing chamber.

Detailed Implementation

[0034] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0035] like Figures 1-5 As shown, a curing and stabilization device for a multi-purpose coated regenerated cellulose membrane includes a curing chamber 22, which extends along a first direction, as shown in the figure. Figure 1 The direction is indicated by the arrow. The curing chamber 22 is equipped with a temperature control device, including a first fan 3. The first fan 3 is located in the curing chamber 22, and its outlet is connected to a heater 4. A circulation duct 5 is connected to the end of the heater 4 furthest from the first fan 3. Several circulation branch pipes 6 are connected to the circulation duct 5 furthest from the heater 4, and the ends of these branch pipes are connected to the interior of the curing chamber 22. A cold air duct 29 is located at the top of the curing chamber 22. One end of the cold air duct 29 is connected to a second fan 12, and the other end is connected to the interior of the curing chamber 22. A temperature sensor 7 is also installed on the curing chamber 22.

[0036] This invention utilizes a first fan 3 and a heater 4 to supply hot air into the curing chamber 22, while a second fan 12 supplies cold air. These two components work together to control the internal temperature of the curing chamber 22, maintaining it within specified parameters. A humidity control device is used to introduce or remove humidity into the curing chamber 22, keeping it within reasonable limits. This reduces issues such as roller slippage, loose edges, adhesion, and discoloration during the coating of the regenerated cellulose film, thus improving the curing effect and ultimately enhancing the final quality of the coated film. Preferably, two temperature control devices are used, and several circulating branch pipes 6 are evenly distributed at the top of the curing chamber 22 to ensure uniform hot air entry.

[0037] A check valve 23 is installed on the cold air duct 29 to prevent the loss of humid and hot gas from the curing chamber 22. The curing chamber 22 is equipped with a humidity sensor 8 and a humidity control unit. The humidity control unit includes a humidifier 14, which is located on one outer wall of the curing chamber 22 along the first direction. The output end of the humidifier 14 is connected to a humidity regulating duct 13, and several humidity regulating branch pipes 25 are located on the humidity regulating duct 13 away from the humidifier 14. The ends of the several humidity regulating branch pipes 25 extend into the curing chamber 22, and the several humidity regulating branch pipes 25 are evenly distributed on the side wall of the curing chamber 22 and communicate with the interior of the curing chamber 22. The humidity control unit also includes a dehumidifier 16, which is located close to the humidifier 14, and its output end is connected to the curing chamber 22 through a dehumidifier duct 15. Specifically, there are two humidity control units, located on the two outer walls of the curing chamber 22 along the first direction, respectively.

[0038] This invention uses a humidifier 14 to add moisture to the curing chamber 22, and a dehumidifier 16 to absorb excess moisture in the curing chamber 22, thereby ensuring stable humidity inside the curing chamber 22. The humidity sensor 8 can detect the humidity inside the curing chamber 22 in real time.

[0039] An ozone generator 1 is installed on the top of the curing chamber 22. The output end of the ozone generator 1 is connected to an ozone duct 2, which is connected to the inside of the curing chamber 22. An ozone concentration sensor 24 is installed on the curing chamber 22. Before the regenerated cellulose membrane is coated and enters the curing chamber 22, ozone is introduced into the curing chamber 22 by the ozone generator 1 for disinfection and to reduce pollution.

[0040] The circulating branch pipe 6 and the cold air duct 29 are both located on the top wall of the curing chamber 22. A temperature buffer is provided on the upper part of the inner wall of the curing chamber 22. The temperature buffer includes a first perforated plate 19, which is located below the circulating branch pipe 6 and the cold air duct 29. The first perforated plate 19 is horizontally positioned and covered with wool felt. In this invention, hot air is buffered by the temperature buffer and dissipates from the perforations of the first perforated plate 19 into the curing chamber 22. During temperature regulation, this prevents the hot air inside the curing chamber 22 from coming into contact with cold air, thus preventing water vapor in the hot air from condensing into water droplets and falling onto the coated regenerated cellulose film. This reduces phenomena such as roller slippage and wrinkling caused by uneven drying when the coated regenerated cellulose film is cured and stabilized.

[0041] The curing chamber 22 has humidity buffers on both inner walls along the first direction. These buffers include a second perforated plate 20 through which moisture enters the curing chamber 22. The second perforated plate 20 is vertically positioned and covered with wool felt. Moisture escapes into the curing chamber 22 through the perforations of the second perforated plate 20, reducing issues such as loose edges, adhesion, and discoloration caused by uneven moisture content on the paper surface during the curing and stabilization of the coated regenerated cellulose film. This ensures uniform drying and moisture content of the coated regenerated cellulose film. The wool felt also provides insulation for the curing chamber 22.

[0042] In this invention, the curing chamber 22 has doors 10 at both ends along the first direction, and each door 10 has two vertically arranged paper guide seams 11. An insulation layer is also provided on each door 10. An instrument box 9 is located at the top of the curing chamber 22. The coated regenerated cellulose membrane enters or exits the curing chamber 22 through the paper guide seams 11.

[0043] The curing chamber 22 has several sets of paper guiding assemblies on its inner walls along both sides in the first direction. These paper guiding assemblies can guide the coated regenerated cellulose membrane from the front end to the rear end of the curing chamber 22 along the first direction via different paths. (Reference) Figure 5 The bold black line represents the coated regenerated cellulose membrane. Specifically, several sets of paper-guiding assemblies are arranged sequentially, one above the other, on the inner wall of the curing chamber 22. Each paper-guiding assembly includes several first pulleys 21, which rotatably rest on the inner wall of the curing chamber 22. A guide roller 18 rotatably rests above each first pulley 21, horizontally positioned, with the first pulleys 21 and guide rollers 18 staggered along a first direction. Two second pulleys 26 rotatably rest on one side of the inner wall of the curing chamber 22 along the first direction. Specifically, the two second pulleys 26 may be located below the paper-guiding assembly. A paper-guiding rope 27 is provided inside the curing chamber 22, positioned on the same side as the second pulleys 26. The paper-guiding rope 27 forms a closed-loop path by passing around the first pulleys 21, guide rollers 18, and two second pulleys 26 located on the same side of the inner wall of the curing chamber 22, guiding the movement of the coated regenerated cellulose membrane.

[0044] Specifically, the coated regenerated cellulose membrane enters from the foremost paper guide slit 11 in the first direction, moves locally along the closed path to the rearmost end of the curing chamber 22 in the first direction, and then exits from the rearmost paper guide slit 11 in the first direction. When the paper guide rope 27 passes over the first pulley 21, the paper guide rope 27 is supported below the coated regenerated cellulose membrane; when the paper guide rope 27 passes under the first pulley 21, the coated regenerated cellulose membrane is sandwiched between the first pulley 21 and the paper guide rope, and the guide roller 18 is similarly positioned. A motor 17 is located outside the curing chamber 22, and a rotating shaft 28 is connected to the output end of the motor 17. The end of the rotating shaft 28 away from the motor 17 extends into the curing chamber 22 and connects to the second pulley 26.

[0045] Specifically, depending on the intended use of the coated regenerated cellulose film, the guide rope 27 passes through several first pulleys 21, several guide rollers 18, and two second pulleys 26 to form different closed-loop paths. This guide rope guides the coated regenerated cellulose film along the closed-loop path within the curing chamber 22, performing curing at the rear end in the first direction. This method can be used to cure coated regenerated cellulose films for different applications. While ensuring stable curing that meets process requirements, it reduces curing time. Along the production direction of the coated regenerated cellulose film, the next process after the curing chamber 22 (e.g., the winding process) has a drive device that moves the coated regenerated cellulose film away from the curing chamber 22, i.e., in the first direction, to tension the film. The guide rope 27 guides the movement of the coated regenerated cellulose film. After the guide rope 27 forms a tensioned closed path, when the motor 17 drives the second pulley 26 to rotate, the guide rope 27 rotates accordingly, and the corresponding guide rollers 18 and first pulleys 21 also rotate, thereby guiding the coated regenerated cellulose film along the movement path of the guide rope 27. When the coated regenerated cellulose membrane breaks, the broken coated regenerated cellulose membrane is pulled out from the feed end of the curing box 22 and tied to the paper guide rope 27. It is then brought to the discharge end of the curing box 22 through the paper guide rope 27, and then manually pulled out of the curing box 22. This solves the problem of excessive paper guiding time after the multi-purpose coated regenerated cellulose membrane breaks.

[0046] The specific operation process is as follows:

[0047] First, turn on the ozone generator 11. Ozone enters the ozone duct 2 from the output end of the ozone generator 1, and then enters the curing chamber 22 for disinfection via the ozone duct 2. Next, open the inlet door 10, and according to the process requirements, wind the paper guide rope 27 around the curing chamber 22. Start the motor 17, refer to... Figure 3 Several paper-feeding assemblies will feed the coated regenerated cellulose membrane into the curing box 22 according to the process paper-feeding route.

[0048] After the paper is drawn, the heater 4 and the first fan 3 are turned on. The hot air generated by the heater 4 enters the curing chamber 22 through the circulating air duct 5. The hot air escapes into the curing chamber 22 through the 2mm perforated plate 19 covered with wool felt to heat the coated regenerated cellulose film. At the same time, the humidifier 14 is turned on. The moisture enters the curing chamber 22 through the humidity regulating air duct 13, and then escapes into the curing chamber 22 through the 2mm perforated plate 20 covered with wool felt to regulate the humidity of the coated regenerated cellulose film.

[0049] When the internal temperature of the curing chamber 22 exceeds the process requirement range, the heater 4 and the first fan 3 are turned off, and the second fan 12 is turned on. The output end of the second fan 12 introduces cold air into the cold air duct 29. The cold air enters the curing chamber 22 to cool it down. After the temperature sensor 7 detects that the temperature has reached the process requirement range, the second fan 12 is turned off.

[0050] When the humidity inside the curing chamber 22 exceeds the process requirement range, the humidifier 14 is turned off and the dehumidifier 16 is turned on. Moisture enters the dehumidifier 16 through the dehumidification duct 15 to reduce the humidity inside the curing chamber 22. After the humidity sensor 8 detects that the humidity has reached the process requirement range, the dehumidifier 16 is turned off.

[0051] After the coating of regenerated cellulose film is cured, it leaves the curing box 22 through the paper guide 11 at the discharge end of the curing box 22.

[0052] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
