Description

Technical Field

[0001] This application relates to the field of defoaming devices, and in particular to a material defoaming device for the production of polyimide films. Background Technology

[0002] Polyimide film is a polymer material with excellent properties such as high strength, high toughness, wear resistance, high temperature resistance, and corrosion resistance. It is widely used in the electrical and electronic industries, especially in the electronics industry where it is a major basic material for various high-end electronic products.

[0003] The existing Chinese patent (authorization announcement number: CN218139180U) mentions a defoaming device for raw materials in polyimide film production. This device uses the cooperation between the stirring shaft and the driven shaft within the raw material stirring mechanism to mix and stir the raw materials in the stirring drum, thereby increasing the stirring quality, improving the stirring effect, and reducing the generation of bubbles. Furthermore, the device is connected to an external exhaust pump via an inlet pipe, allowing the pump to extract air from the stirring drum, creating a negative pressure state inside. This pressure then expels the generated bubbles, eliminating them and further improving the quality of the finished product. This enhances the practicality of the device, meets current usage requirements, and the invention is simple in structure and easy to use.

[0004] While existing defoaming devices can uniformly stir materials to reduce the formation of bubbles, dimethylacetamide and dimethylformamide, which are raw materials used in the production of polyimide films, have a certain irritating odor. During the defoaming process, as the temperature rises and the stirring action intensifies, solvent evaporation intensifies, which may cause odors to emanate, thus affecting the working environment and making it inconvenient for workers to perform their tasks. Utility Model Content

[0005] The purpose of this application is to provide a defoaming device for materials used in the production of polyimide film, in order to solve the problem that odors may be emitted, thereby affecting the working environment and making it inconvenient for workers to work.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A defoaming device for polyimide film production includes a base, a stirring device fixedly connected to the top of the base, a rotary motor fixedly connected to the top of the stirring device, an output shaft of the rotary motor passing through the stirring device and fixedly connected to a rotating rod, the output shaft of the rotary motor being rotatably connected to the stirring device, a plurality of stirring rods being symmetrically fixedly connected to the outer side of the rotating rod, a feed pipe fixedly connected to the top of the stirring device and communicating with the stirring device, a discharge pipe fixedly connected to the discharge end of the stirring device, the end of the discharge pipe away from the stirring device passing through the base, an adsorption mechanism being provided on the top of the base, and a sealing mechanism being provided on the outer side of the feed pipe.

[0008] By adopting the above technical solution, the raw materials are poured into the mixing equipment through the feed pipe. Then, the rotary motor is started to drive the stirring rod to rotate, so that the raw materials are continuously tumbling and mixing in the mixing equipment, which increases the interaction between the raw materials, helps to break up bubbles and reduce the generation of bubbles. When the mixing and defoaming process is completed, the control valve of the discharge pipe is opened to send out the raw materials. The adsorption mechanism can adsorb the drifting odor, and the sealing mechanism can seal the opening of the feed pipe.

[0009] Furthermore, the adsorption mechanism includes a column fixedly connected to the top of the base, a recycling frame fixedly connected to the top of the column, a fixed frame fixedly connected to the inner side of the recycling frame, a movable plate slidably arranged on the inner side of the fixed frame, a plurality of through holes opened on the top of the movable plate, bamboo charcoal stones placed on the top of the movable plate, an air inlet pipe fixedly connected between the recycling frame and the stirring device, the recycling frame and the stirring device being connected through the air inlet pipe, an air outlet pipe fixedly connected to the outer side of the recycling frame, and the recycling frame being connected to the air outlet pipe.

[0010] By adopting the above technical solution, the irritating gas first comes into contact with the bamboo charcoal stone in the fixed frame. The bamboo charcoal stone can adsorb the irritating odor molecules in the gas through physical adsorption. Then, the gas after being adsorbed by the bamboo charcoal stone is finally discharged through the gas outlet pipe, thereby reducing the odor in the emitted gas.

[0011] Furthermore, a drive motor is fixedly connected to the outside of the recycling frame, and the output shaft of the drive motor passes through the recycling frame and is fixedly connected to a striking block. The output shaft of the drive motor is rotatably connected to the recycling frame, and the striking block abuts against the moving plate when it rotates.

[0012] By adopting the above technical solution, bamboo charcoal stones in different locations can have the opportunity to fully contact the gas.

[0013] Furthermore, the inner side of the fixed frame is symmetrically provided with sliding grooves, and the outer side of the movable plate is symmetrically fixedly connected with sliders, which are slidably connected to the sliding grooves.

[0014] By adopting the above technical solution, the moving plate can maintain the correct motion trajectory when it moves.

[0015] Furthermore, the bottom of the fixed frame has two bottom blocks that are symmetrically fixedly connected, and the top of the bottom blocks is fixedly connected to a spring, the top of the spring being fixedly connected to the movable plate.

[0016] By adopting the above technical solution, it is easier to strike the block next time.

[0017] Furthermore, the closing mechanism includes rotating seats symmetrically and fixedly connected to the outside of the feed pipe, a rotating shaft rotatably connected between the two rotating seats, a rotating plate fixedly connected to the outside of the rotating shaft, the rotating plate being adapted to the feed pipe, a rotating rod rotatably connected to the outside of one of the rotating seats, one end of the rotating rod passing through the rotating seat and fixedly connected to the rotating shaft, and a torsion spring sleeved on the outside of the rotating rod.

[0018] By adopting the above technical solution, when the rotating plate is released after the material is added, the elastic potential energy of the torsion spring is released, causing the rotating plate to move above the feed pipe, thereby reducing the risk of odor dispersion.

[0019] In summary, this application includes at least one of the following beneficial effects;

[0020] 1. In this application, when treating irritating odors, bamboo charcoal stone can adsorb irritating odor molecules in the gas through physical adsorption. Then, the gas after adsorption by bamboo charcoal stone is finally discharged through the gas outlet pipe, thereby reducing the odor in the exhaust gas, improving the air quality of the working environment, and protecting the health of operators.

[0021] 2. In this application, when the rotating plate is released after the material is added, the elastic potential energy of the torsion spring is released, causing the rotating plate to move above the feed pipe, thereby reducing the risk of odor dispersion and reducing the entry of impurities into the mixing equipment.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a material defoaming device for polyimide film production.

[0030] Reference Figure 1 and Figure 2 A defoaming device for polyimide film production includes a base 1, a stirring device 2 fixedly connected to the top of the base 1, a rotary motor 3 fixedly connected to the top of the stirring device 2, the output shaft of the rotary motor 3 passing through the stirring device 2 and fixedly connected to a rotating rod 4, the output shaft of the rotary motor 3 being rotatably connected to the stirring device 2, several stirring rods 5 being symmetrically fixedly connected to the outer side of the rotating rod 4, a feed pipe 6 fixedly connected to the top of the stirring device 2, the feed pipe 6 being connected to the stirring device 2, a discharge pipe 7 fixedly connected to the discharge end of the stirring device 2, the end of the discharge pipe 7 away from the stirring device 2 passing through the base 1, an adsorption mechanism being provided on the top of the base 1, and a sealing mechanism being provided on the outer side of the feed pipe 6.

[0031] First, the prepared raw materials are poured into the mixing device 2 through the feed pipe 6. Then, the rotary motor 3 is started to drive the stirring rod 5 to rotate, so that the raw materials are continuously tumbling and mixing in the mixing device 2, which increases the interaction between the raw materials, helps to break up bubbles and reduce the generation of bubbles. When the mixing and defoaming process is completed, the control valve of the discharge pipe 7 is opened to send out the raw materials. The adsorption mechanism can adsorb the drifting odor, and the sealing mechanism can seal the opening of the feed pipe 6.

[0032] Reference Figures 1 to 3 The adsorption mechanism includes a column 8 fixedly connected to the top of the base 1, a recycling frame 9 fixedly connected to the top of the column 8, a fixed frame 10 fixedly connected to the inner side of the recycling frame 9, a movable plate 11 slidably arranged on the inner side of the fixed frame 10, a number of through holes opened on the top of the movable plate 11, bamboo charcoal stone placed on the top of the movable plate 11, an air inlet pipe 12 fixedly connected between the recycling frame 9 and the stirring device 2, and the recycling frame 9 and the stirring device 2 are connected through the air inlet pipe 12, and an air outlet pipe 13 fixedly connected to the outer side of the recycling frame 9, and the recycling frame 9 and the air outlet pipe 13 are connected.

[0033] A drive motor 14 is fixedly connected to the outside of the recycling frame 9. The output shaft of the drive motor 14 passes through the recycling frame 9 and is fixedly connected to a drive rod 15. The output shaft of the drive motor 14 is rotatably connected to the recycling frame 9. A striking block 16 is fixedly connected to the outside of the drive rod 15. When the striking block 16 rotates, it abuts against the moving plate 11.

[0034] In addition, the inner side of the fixed frame 10 is symmetrically provided with sliding grooves 17, and the outer side of the movable plate 11 is symmetrically fixedly connected with sliders, which are slidably connected to the sliding grooves 17.

[0035] Furthermore, the bottom of the fixed frame 10 is symmetrically fixedly connected to two bottom blocks 18, and the top of the bottom blocks 18 is fixedly connected to a spring 19, the top of the spring 19 being fixedly connected to the movable plate 11.

[0036] When treating irritating odors, the irritating odors first enter the recovery box 9 through the air inlet pipe 12. The irritating gas entering the recovery box 9 first comes into contact with the bamboo charcoal stone in the fixed frame 10. The bamboo charcoal stone can adsorb the irritating odor molecules in the gas through physical adsorption. Then, the gas after being adsorbed by the bamboo charcoal stone is finally discharged through the air outlet pipe 13, thereby reducing the odor in the exhaust gas, improving the air quality of the working environment, and protecting the health of the operators.

[0037] During prolonged use, the drive motor 14 is activated to rotate the drive rod 15. The rotation of the drive rod 15 causes the striking block 16 to contact the moving plate 11. The moving plate 11 moves under the force, and the bamboo charcoal stone on the top of the moving plate 11 is displaced, so that the bamboo charcoal stone in different positions has the opportunity to fully contact the gas, reducing the risk of excessive adsorption in some parts of the bamboo charcoal stone and insufficient adsorption in other parts.

[0038] When the movable plate 11 moves, the slider and the groove 17 provide guidance for the movable plate 11, so that the movable plate 11 can maintain the correct movement trajectory when it moves.

[0039] When the movable plate 11 moves, the movement of the movable plate 11 stretches the spring 19, causing the spring 19 to compress and generate elastic potential energy. When the striking block 16 moves away from the movable plate 11, the spring 19 returns to its original position, causing the movable plate 11 to return to its original position, making it easier for the striking block 16 to strike again.

[0040] Reference Figure 1 and Figure 2 The closing mechanism includes rotating seats 20 symmetrically and fixedly connected to the outside of the feed pipe 6. A rotating shaft is rotatably connected between the two rotating seats 20. A rotating plate 21 is fixedly connected to the outside of the rotating shaft. The rotating plate 21 is adapted to the feed pipe 6. A rotating rod 22 is rotatably connected to the outside of one rotating seat 20. One end of the rotating rod 22 passes through the rotating seat 20 and is fixedly connected to the rotating shaft. A torsion spring 23 is sleeved on the outside of the rotating rod 22.

[0041] After the materials are added, the staff manually rotates the rotating plate 21. The rotation of the rotating plate 21 drives the rotating shaft, which in turn drives the rotating rod 22 to rotate. The rotation of the rotating rod 22 causes the torsion spring 23 to be compressed, generating elastic potential energy. When the materials are added, the rotating plate 21 is released. At this time, the elastic potential energy of the torsion spring 23 is released, causing the rotating plate 21 to move above the feed pipe 6, thereby reducing the risk of odor dispersion and reducing the entry of impurities into the mixing equipment 2.

[0042] Working principle: Raw materials are poured into the mixing equipment 2 through the feed pipe 6. Then, the rotary motor 3 is started to drive the stirring rod 5 to rotate, so that the raw materials are continuously tumbling and mixing in the mixing equipment 2. This increases the interaction between the raw materials, helps to break up bubbles, and reduces the generation of bubbles. When the mixing and defoaming process is completed, the control valve of the discharge pipe 7 is opened to send the raw materials out. They enter the recovery frame 9 through the air inlet pipe 12. The irritating gas entering the recovery frame 9 first comes into contact with the bamboo charcoal stone in the fixed frame 10. The bamboo charcoal stone can adsorb the irritating odor molecules in the gas through physical adsorption. Then, the gas after being adsorbed by the bamboo charcoal stone is finally discharged through the air outlet pipe 13, thereby reducing the odor in the exhaust gas.
