Description

Technical Field

[0001] This invention relates to the field of thin film production technology, specifically a drying device for thin film processing with temperature control function. Background Technology

[0002] In the field of film processing, dryers are core equipment for achieving quality control of film substrates, and are widely used in the production chain of various sub-sectors such as food packaging, electronic substrates, medical protective films, and optical films. Their core function is to remove residual solvents or moisture from the film during previous processes such as extrusion, coating, and lamination through controlled heating, ultimately ensuring that the key properties of the finished film, such as moisture content, flatness, mechanical strength, and dimensional stability, meet standards.

[0003] In existing drying equipment, most use solid drying rollers as film introduction devices. Solid rollers have no heat dissipation channels inside, and heat is easily accumulated inside the roller body after heating, causing the roller surface temperature to rise continuously and be difficult to adjust quickly. As a result, the film is damaged due to local overheating. When the production line needs to reduce the drying temperature or switch processes, the cooling lag time of solid rollers is longer, and they cannot match the changes in process parameters in time.

[0004] Existing drying equipment is mostly single-sided drying. Single-sided heating leads to a significant difference in the rate of moisture evaporation on both sides of the film. The side in contact with the heated surface loses moisture quickly, while the other side has low evaporation efficiency due to the lag in heat transfer. Therefore, it is easy for one side to be over-dried while the other side is not completely dried. Summary of the Invention

[0005] The purpose of this invention is to provide a drying device for thin film processing with temperature control function to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drying device for thin film processing with temperature control function, the drying device including a drying cylinder, a film guiding mechanism, a drying mechanism and a control box, wherein the film guiding mechanism and the drying mechanism are both disposed inside the drying cylinder, and the film guiding mechanism includes a temperature-sensing film guiding element and a film distance control element; The control box is electrically connected to the temperature-sensing film guiding element, the film spacing control element, and the drying mechanism. The temperature-sensing film guiding element and the film spacing control element are connected. During the film drying process, the control box adjusts the guide spacing of the film spacing control element according to the film thickness. After the guide spacing is adjusted, the control box controls the film guiding mechanism to guide the film into the drying mechanism. The drying mechanism dries the film. The temperature-sensing film guiding element detects the drying temperature, and the detected data is displayed on the control box. The drying temperature of the drying mechanism can be adjusted in real time based on the detected data.

[0007] The temperature-sensitive film guiding element includes a film guiding roller, a temperature sensing element, a drive source, and a connecting key. The temperature sensing element is disposed inside the film guiding roller via the connecting key. The film guiding roller is rotatably connected to the drive source, and the drive source is connected to a film distance control element. The film guiding roller has a perforated mesh design. The temperature sensing element is a temperature sensor. The drive source is a drive motor. When the drive source operates, it drives two film guiding rollers to rotate, one of which rotates counterclockwise and the other rotates clockwise, guiding the film into the interior of the drying cylinder. The temperature sensing element can detect the temperature inside the drying cylinder in real time.

[0008] The film distance control element includes a drive source bracket and a hydraulic cylinder. The drive source is mounted on the drive source bracket, and the output end of the hydraulic cylinder is connected to the drive source bracket. According to the thickness of the film, the control box controls the operation of two hydraulic cylinders to adapt to films of different thicknesses by adjusting the distance between the two guide films.

[0009] The drying mechanism includes a heating tube, a heat-conducting perforated plate, a heat-resistant frame, and a fixing key. The heating tube is mounted on the heat-resistant frame, which is connected to the fixing key. The fixing key is located on the inner wall of the drying cylinder. The heat-conducting perforated plate is located on the inner wall of the drying cylinder and is positioned between the heating tube and the film guiding mechanism. The heat-conducting perforated plate isolates the heating tube from the film guiding mechanism, blocking direct heat transfer from the heating tube to the film guiding mechanism. The heating tube acts as a heat source, and the heat-conducting perforated plate evenly releases the heat output from the heating tube, preventing the high temperature of the heating tube from directly radiating onto the film and preventing localized overheating or deformation of the film. The control box can control the power of the heating tube based on the temperature data detected by the temperature sensing element, thereby adjusting the real-time temperature inside the drying cylinder.

[0010] The drive source and the membrane distance control element are covered by a heat insulation shell. The output end of the drive source passes through the heat insulation shell. A support element is provided below the membrane distance control element. The heat insulation shell provides protection for the membrane distance control element and reduces the impact of high temperature on the membrane distance control element. The support element provides support for the membrane distance control element.

[0011] The film gap control element is mounted on the support block, which passes through the drying cylinder. The drying cylinder is mounted on the cylinder support, and both the support block and the cylinder support are mounted on the support base. The support base is equipped with a feeding mechanism and a collecting mechanism. The cylinder support supports the drying cylinder. The feeding mechanism guides the film into the interior of the drying cylinder, and the collecting mechanism removes and collects the dried film from the interior of the drying cylinder.

[0012] The feeding mechanism includes a feeding roller, a roller support, a first drive source, and a drive source fixing key. The feeding roller is rotatably disposed between the roller support and the first drive source. The drive source fixing key is sleeved on the first drive source. Both the drive source fixing key and the first drive source are disposed inside the roller support. The roller support is disposed on a support base. The first drive source is a drive motor. The control box controls the operation of the first drive source. The output shaft of the first drive source drives the feeding roller to rotate, guiding the film into the interior of the drying cylinder for drying.

[0013] The receiving mechanism includes a receiving roller, a second drive source, and a C-shaped bracket. The second drive source is mounted on the C-shaped bracket, and the receiving roller is rotatably positioned between the second drive source and the second drive source. The C-shaped bracket is mounted on a support base. The second drive source is a drive motor, and the control box controls the operation of the second drive source. The output shaft of the second drive source drives the receiving roller to rotate, thus exporting and collecting the dried film from the inside of the drying cylinder.

[0014] The control box is mounted on the support base. The control box is electrically connected to both the feeding mechanism and the receiving mechanism. The control box controls the operation of the drive source within the feeding mechanism and the receiving mechanism through electrical signals.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The guide roller of the drying equipment features a perforated mesh design, which significantly reduces the amount of metal used in the roller. The guide roller can quickly absorb ambient heat from the drying cylinder, preventing excessive temperature differences between the roller and the film. The air inside the guide roller can convect with the external hot air through the heat dissipation holes, preventing the roller temperature from becoming too high and causing the film to shrink due to localized overheating. Conversely, if the ambient temperature is slightly lower, the heat dissipation holes can also allow the guide roller to absorb more heat from the hot air, maintaining its own temperature stability, which is equivalent to providing constant temperature contact support for the film.

[0016] The circumferentially arranged heating tubes prevent uneven heating caused by one-sided drying. The design of the heat-conducting plate prevents the high temperature of the heating tubes from directly radiating onto the film. The heat-conducting plate itself first absorbs the concentrated heat of the heating wire and then releases it evenly across the entire plate surface, allowing the heat to be transferred to the film more evenly. At the same time, it protects the film from damage caused by localized high temperatures, ensuring that the film is heated evenly.

[0017] By combining the temperature sensor and the guide roller with a temperature-sensitive guide element, the temperature sensor is positioned closer to the film, thereby accurately detecting the drying temperature near the film and avoiding the effects of uneven local temperature within the drying cylinder, which could lead to overheating or incomplete drying of the film.
