Description

Technical Field

[0001] The present invention relates to the technical field of release films, and in particular to a uniform water-based silicone oil polyester release film and a preparation device and method thereof. Background Art

[0002] Uniform water-based silicone polyester release film is a film used for coating industrial materials. It is usually composed of water-based silicone oil, polyester base, curing agent and auxiliary materials. The main function of this film is to be used as a coating substrate in industrial production. It can provide good anti-adhesive, isolation and protection properties, so that the coated material can be easily separated from the substrate and will not be affected by the external environment during the processing. This type of release film usually needs to be cured during the production process to ensure the performance and quality of the coated material.

[0003] In the prior art, a Chinese patent document with publication number CN117088163A discloses a release film material for a chip capacitor and a preparation method and device thereof, wherein a mounting roller, a plurality of tightening rollers and a winding roller are matched to make the release film material taut in a cutting area for winding, a corresponding electric push rod is started to drive the corresponding guide rail to descend, so that the corresponding cutting assembly matches the release film material, and at the same time, a driving assembly is started to drive the driving shaft to rotate on the guide rail, and drive the two sliding seats on the guide rail to translate toward or away from each other, and the release film material is cut by a plurality of cutting assemblies after adjusting the position, so as to complete the cutting of the release film material according to the cutting quantity requirements. With the above structure, When cutting the release film material, the degree of automation is higher, thereby reducing labor costs, and traditional equipment uses low-temperature curing, which leads to slow curing efficiency and affects production efficiency, and uses a simple air supply method, such as a single-direction air supply port or fan, which leads to uneven airflow distribution in the curing box. Since the flow direction and speed of the cold air cannot be effectively controlled, the preparation speed and product quality will be affected, which will cause the preparation speed in some areas to be too fast and the preparation speed in other areas to be too slow, affecting the overall curing effect. Therefore, the present invention application provides a uniform water-based silicone oil polyester release film and a preparation method and preparation equipment thereof to meet the preparation requirements of release film curing and guided air supply.

[0019] Beneficial effects of the present invention:

[0020] (1) In the preparation equipment of the uniform water-based silicone oil polyester release film provided in the present application, an air supply component and a guide component are provided. The air supply component conveys cold air to the inside of the curing box through the cold air duct, thereby accelerating the preparation speed of the release film. At the same time, the setting of the guide box allows the cold air to cover most or all of the entire surface of the release film, thereby ensuring the uniformity and sufficiency of the air flow during the preparation process. The stepped setting of the guide grille increases the contact area between the air flow and the surface of the release film, further improving the contact efficiency between the air flow and the release film, thereby helping to accelerate the preparation process and improve production efficiency. The gap between the air inlet and the second cold air duct prevents the cold air from being directly discharged downward through the guide box, and the flow rate and speed of the cold air can be adjusted according to the specific gap conditions, thereby controlling the cooling effect.

[0021] (2) In the preparation equipment of uniform water-based silicone oil polyester release film provided in the present invention, by arranging a lifting structure on the guide assembly, the precise position adjustment of the guide box can be achieved by adjusting the rotation of the threaded rod. By adjusting the position of the guide box, the flow direction and speed of the cold air can be controlled, thereby optimizing the cooling effect. When necessary, the cold air can be directed to a specific area of ​​the release film, which can more effectively cool the release film and improve the stability and efficiency of the preparation process. At the same time, during the curing process, the temperature of thermal curing (i.e., heating curing) can be at a high temperature condition, which increases the curing rate of the release film and improves the production efficiency. Adjusting the position of the guide box can adjust the cooling effect and ensure the control of the preparation process parameters of the release film. It can also enable the cold air to more fully cover the working area, thereby improving the utilization efficiency of the cold air and helping to save energy and costs to a certain extent.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0037] like Figures 1 to 10 As shown, in the first aspect, the present invention provides a uniform water-based silicone oil polyester release film preparation device, which includes a positioning box 1, a conveying mechanism 2 is arranged on the top of the positioning box 1, and the conveying mechanism 2 is used to convey the release film to be processed, and a curing box 10 is arranged on the top of the positioning box 1, and the curing box 10 is used to perform a curing operation on the release film. Two guide boxes 8 are respectively arranged on both sides of the curing box 10, and door curtains 9 are arranged under the two guide boxes 8; an air supply component is arranged on the back of the positioning box 1, and the air supply component is used to cool the release film during molding and curing. The air supply component includes a cold air duct 17 installed on the back of the positioning box 1 and the curing box 10, and a condenser 16 installed on one side of the positioning box 1, and the condenser 16 is connected to the bottom of the cold air duct 17; the guide component is arranged on both sides of the interior of the curing box 10, and the guide component is used to guide the wind force sent by the air supply component to further control the preparation and molding effect of the release film. The guide component includes a first guide box 20 and a second guide box movably installed on both sides of the interior of the curing box 10; a heat curing box 12 is arranged inside the curing box 10, and a top cover 11 is arranged on the top of the curing box 10.

[0038] The release film to be processed is conveyed from the top of the positioning box 1 into the preparation equipment through the conveying mechanism 2, and the release film enters the curing box 10 for curing operation. At the same time, the air supply component is started for cooling treatment to ensure the preparation speed and quality of the release film. The air supply component includes a cold air duct 17 and a condenser 16, which is used to cool the release film during the molding preparation process, which helps to quickly reduce the temperature of the release film, improve the preparation process of the release film as much as possible, and ensure that the cold air evenly covers most or all of the entire release film surface, thereby improving the cooling efficiency of the release film. The guide component guides the incoming wind force to achieve the cooling effect after thermal curing. At the top of the curing box 10, the thermal curing box 12 provides heating and curing to accelerate the preparation process of the water-based silicone oil release film. After the release film is cured and cooled, it can also be taken out through the conveying mechanism 2 for processing or use in the next step.

[0039] like Figure 1 , Figure 2 , Figure 3 As shown, two connecting holes 13 are further provided on both sides of the heat curing box 12, and a suction fan 14 is installed on one side of the top of the curing box 10, and the other end of the suction fan 14 passes through the curing box 10 and is connected with the connecting hole 13, and a fan turntable is provided at the connection between the suction fan 14 and the suction air duct 15, and two air outlets are provided on the top of the fan turntable; a second cold air duct 18 is provided on one side of the top of the cold air duct 17, and a first cold air duct 19 is provided on the other side of the top of the cold air duct 17, and the second cold air duct 18 and the first cold air duct 19 have two air inlet ducts at the bottom respectively, and the air inlet ducts pass through the top of the curing box 10.

[0040] The heat curing box is started to heat and cure the release film. At the same time or subsequently, the suction fan 14 is started to absorb the waste gas generated during the preparation process and the heat generated inside. The absorbed waste gas and heat are discharged from the air outlet position above the fan turntable to ensure that the temperature of the working environment is suitable and the environment is clean. When the cold air fan is started, cold air is transported to the inside of the curing box 10 through the cold air duct 17, the second cold air duct 18 and the first cold air duct 19 to cool the cured hot release film, control or increase the preparation process speed of the release film, and through the above-mentioned adjustment of the preparation method of the release film, the release film preparation process can be completed in a shorter or more appropriate time, thereby improving the production efficiency of the release film preparation, and by timely absorbing waste gas and heat and providing cold air during the preparation process, the energy utilization efficiency is improved.

[0041] like Figures 1 to 10As shown, first air inlets 21 are provided on both sides of the top surface of the first guide box 20, and the first air inlets 21 respectively correspond to the air inlet pipes at the bottom of the first cold air duct 19, and the first air inlet 21 is not connected to the air inlet pipes at the bottom of the first cold air duct 19, and there is a gap between them. A plurality of guide grilles 22 are rotatably installed at the bottom of the first guide box 20, and the plurality of guide grilles 22 are arranged in a stepped shape, and a first positioning plate 23 for positioning the plurality of guide grilles 22 is arranged inside the first guide box 20; a driving motor 38, a compressor 39, an air duct 40, a first air knife 41, and a second air knife 42 are provided on the first guide box 20, and the driving motor 38 drives the compressor 39 to rotate to compress the air, and the air is discharged into the air duct 40 after the air pressure reaches a certain pressure, and is discharged from the first The wind knife 41 and the second wind knife 42 are discharged to form a horizontal plane type first airflow; the second air inlet is arranged on both sides of the top surface of the second guide box, and the second air inlet corresponds to the air inlet at the bottom of the second cold air duct 18 respectively, and the second air inlet is not connected to the air inlet at the bottom of the second cold air duct 18, and there is also a gap, and a plurality of guide grilles are rotatably installed at the bottom of the second guide box, and the plurality of guide grilles are arranged in a stepped shape, and a second positioning plate for positioning the plurality of guide grilles is arranged inside the guide box; the second guide box is provided with a driving motor 2, a compressor 2, an air duct 2, a wind knife 1, and a wind knife 2, and the driving motor 2 drives the compressor 2 to rotate and compress the air, and the air pressure reaches a certain pressure and is discharged into the air duct 2, and is discharged from the wind knife 1 and the wind knife 2, to form a horizontal plane type second airflow. Obviously, the structure, connection method, working principle, and working method of the first guide box and the second guide box can be completely the same, or they can be partially different.

[0042] Since there is a gap between the first air inlet 21 and the air inlet duct of the first cold air duct 19, and there is a gap between the second air inlet and the air inlet duct of the second cold air duct 18, the cold air will not be directly discharged downward through the first guide box 20 and the second guide box. This design can adjust the flow and speed of the cold air according to the specific gap conditions, and then control the cooling effect. By adjusting the gap size between the first air inlet 21 and the air inlet duct at the bottom of the first cold air duct 19, and the gap size between the second air inlet and the air inlet duct at the bottom of the second cold air duct 18, the cooling effect inside the first guide box 20 and the second guide box can be flexibly adjusted to meet the needs of different processes and products.

[0043] Accordingly, in order to obtain different cooling effects to meet the needs of different processes and products, the uniform water-based silicone oil polyester release film preparation equipment includes a first cooling coefficient C1 and a second cooling coefficient C2, C1=F1 / D1+F2 / D2, C2=F3 / F1+F4 / F2, satisfying: 0.1≤C1≤8, 3≤C2≤10, wherein F1 is the air intake pressure of the first air inlet 21, F2 is the air intake pressure of the second air inlet, F3 is the pressure of the first air flow, F4 is the pressure of the second air flow, D1 is the gap between the first air inlet 21 and the air inlet pipe of the first cold air duct 19, and D2 is the gap between the second air inlet 21 and the air inlet pipe of the second cold air duct 18.

[0044] Obviously, the first cooling coefficient C1 and the second cooling coefficient C2 can be adjusted to obtain different cooling effects. For example, the second cooling coefficient C2 is 10, and the first cooling coefficient C1 is 8, that is, the pressure of the horizontal plane first airflow and the horizontal plane second airflow are both very high, the gap between the first air inlet 21 and the air inlet of the first cold air duct 19 is small and the air inlet pressure is high, and the gap between the second air inlet 21 and the air inlet of the second cold air duct 18 is small and the air inlet pressure is high, so that the cold air basically does not rise and flow out, and the corresponding cooling will form a relatively good covering airflow guide, and the covering airflow can quickly and effectively cover most or all of the release film surface, accelerate and optimize the cooling effect, guide the cold air to the release film or a specific area in the curing box 10, and improve the preparation process speed and preparation efficiency of the release film.

[0045] Furthermore, the uniform water-based silicone oil polyester release film preparation equipment can also include: a third cooling coefficient C3 and a fourth cooling coefficient C4, C3=|(V1-V2) / (D1-D2)-V1 / D1-V2 / D2|, C4=(V3-V1) / (V3+V1)+(V4-V2) / (V4+V2), satisfying: 2≤C3≤6, 1.2≤C4<2, wherein V1 is the air intake velocity at the first air inlet 21, V2 is the air intake velocity at the second air inlet, V3 is the velocity of the first air flow, and V4 is the velocity of the second air flow.

[0046] On the basis of the first cooling coefficient C1 and the second cooling coefficient C2, the third cooling coefficient C3 and the fourth cooling coefficient C4 can be further used to obtain different cooling effects. For example, D1 is not equal to D2, the fourth cooling coefficient C4 is 1.8, and the third cooling coefficient C3 is 6, that is, the airflow speed of the horizontal plane first airflow and the horizontal plane second airflow is very large, so that the cold air basically does not rise and flow out; at the same time, the gap between the first air inlet 21 and the air inlet pipe of the first cold air duct 19 can also be small and the air intake speed (i.e., the air intake rate) is also large, and the gap between the second air inlet 21 and the air inlet pipe of the second cold air duct 18 can also be small and the air intake (i.e., the air intake rate) is also large. The corresponding cooling will form a faster covering airflow guide, and the covering airflow can more effectively cover most or all of the release film surface, appropriately improve the accelerated optimization cooling effect, and improve the efficiency of the process.

[0047] It should be noted that the air intake pressure F1 of the first air inlet 21, the air intake pressure F2 of the second air inlet, the pressure F3 of the first air flow, and the pressure F4 of the second air flow can all be measured by conventional pressure sensors; the gap D1 between the first air inlet 21 and the air inlet pipe of the first cold air duct 19, and the gap D2 between the second air inlet 21 and the air inlet pipe of the second cold air duct 18 can all be measured or analyzed by conventional distance measuring sensors; the air intake speed V1 of the first air inlet 21, the air intake speed V2 of the second air inlet, the speed V3 of the first air flow, and the speed V4 of the second air flow can all be measured or analyzed by conventional flow meters, and the first cooling coefficient C1, the second cooling coefficient C2, the first The third cooling coefficient C3 and the fourth cooling coefficient C4 are used to evaluate the cooling effect of the release film. The first cooling coefficient C1, the second cooling coefficient C2, the third cooling coefficient C3, and the fourth cooling coefficient C4 can be used to control the pressure and speed of the cold air. The pressure F1 and F2 of the cold air intake and the intake velocities V1 and V2 can also be jointly controlled to jointly control the pressure F3 and F4 of the first airflow and the second airflow and the velocities V3 and V4 to obtain different first cooling coefficients C1, second cooling coefficients C2, third cooling coefficients C3, and fourth cooling coefficients C4, and correspondingly obtain different cooling effects, thereby completing the preparation process control of the release film and improving the application scope of the release film preparation process.

[0048] At the same time, since both the horizontal plane type first airflow and the horizontal plane type second airflow have a certain pressure, the cold air will not rise and flow out as much as possible. Accordingly, the incoming air enters the first guide box 20 and the second guide box from both sides of the top surface, and the pressure and speed of the cold air can be controlled by the first cooling coefficient C1, the second cooling coefficient C2, the third cooling coefficient C3, and the fourth cooling coefficient C4, and a covering airflow guide can be formed. This covering airflow can effectively cover most or all of the release film surface, ensuring the uniformity and sufficiency of the airflow during the cooling process, and the first guide The guide grilles in the box 20 and the second guide box are arranged in a stepped shape, which can also increase the contact area between the airflow and the surface of the release film, thereby improving the contact efficiency between the airflow and the release film, helping to accelerate the cooling process, improve the preparation process speed and preparation efficiency of the release film, and improve the production efficiency of the release film. The first guide box 20 and the second guide box are provided with a first positioning plate 23 and a second positioning plate for positioning a plurality of guide grilles 22. This arrangement ensures the accurate positioning of the guide grilles 22, so that the airflow can accurately flow through the surface of the release film, further improving the scope of application of the release film preparation process.

[0049] Fixed plates 27 are installed on both sides of the top surface of the transmission mechanism 2, guide columns 28 are set on both sides of the fixed plate 27, a threaded rod 29 is rotatably installed in the middle of the fixed plate 27, and a movable plate 30 is slidably installed on the two guide columns 28 and the threaded rod 29. The threaded holes set on the movable plate 30 are adapted to the threaded rod 29, and the guide box 20 is installed between the two movable plates 30. A transmission box 24 is also provided on the back of the positioning box 1, and a servo motor is provided inside the transmission box 24. The output end of the servo motor is fixedly connected to a rotating rod 25, and driving gears 26 are sleeved on both sides of the rotating rod 25. The bottom ends of the two threaded rods 29 are sleeved with driven gears adapted to the driving gear 26.

[0050] The servo motor drives the rotating rod 25, and the rotating rod 25 drives the driving gear 26 to rotate, thereby driving the driven gear. The driven gear is connected to the threaded rod 29, so that the threaded rod 29 rotates, and the movable plate 30 slides up and down along the threaded rod 29. By adjusting the rotation of the threaded rod 29, the precise position adjustment of the first guide box 20 and the second guide box can be achieved. Adjusting the position of the first guide box 20 and the second guide box can control the flow direction and speed of the cold air. The horizontal plane type first airflow and the horizontal plane type second airflow prevent part or all of the cold air from flowing out from above, thereby optimizing the cooling effect and guiding the cold air to the release film or The specific area within the curing box 10 can more effectively cool the release film or the curing box 10, improve the stability and efficiency of the preparation process of the release film, and control the temperature distribution of the release film or the curing box 10. At the same time, during the curing process, the temperature of thermal curing (i.e., heating curing) can be at a high temperature, which increases the curing rate of the release film and improves production efficiency. Adjusting the position of the guide box can adjust the cooling effect, ensure the control of the preparation process parameters of the release film, and allow the cold air to more fully cover the working area, thereby improving the utilization efficiency of the cold air and helping to save energy and costs to a certain extent.

A rotating motor 5 is arranged on one side of the bottom of the conveying mechanism 2, and the output end of the rotating motor 5 is connected to one of the conveyor belts 4 with a belt transmission. First positioning pieces 6 are arranged on both sides of the top of the conveying mechanism 2, and a second positioning piece 7 is arranged on the top of the conveying mechanism 2. The two sides of the second positioning piece 7 are respectively mounted on the two first positioning pieces 6, and a plurality of through holes are opened on the second positioning piece 7, and the second positioning piece 7 is directly opposite to the position of the curing box 10 above. A bottom air outlet 31 is also arranged in the middle of the bottom end of the conveying mechanism 2. The scoop 31 is located below the second positioning piece 7, and the bottom air outlet scoop 31 is located inside the positioning box 1. A through hole 32 is provided at the bottom end of the bottom air outlet scoop 31. The cross section of the bottom air outlet scoop 31 is in an inverted trapezoidal shape.

By guiding the gas inside the curing box 10 to flow to the air outlet hopper, the temperature distribution in the curing box 10 can be properly adjusted. During the preparation process, the hot air is discharged through the through hole, and the temperature inside the curing box 10 can be properly adjusted.
