Abstract
Description
Technical Field
[0001] This utility model relates to the field of thin film production technology, and in particular to a defoaming structure for mixing raw materials in thin film production. Background Technology
[0002] The field of film production technology is a broad and complex one, involving a variety of materials, processes and equipment. Films generally refer to plastic film products made of materials such as polypropylene, polyethylene, polyester, and polystyrene, with a thickness of less than 0.25mm, that are flat, glossy or matte, transparent or opaque, and relatively stiff or soft.
[0003] During its production process, the raw materials need to be defoamed.
[0004] However, traditional defoaming structures for mixing raw materials in film production use a fixed and simple mixing method, which cannot be adjusted according to the amount of raw materials being mixed. This results in some parts of the mixing structure not being able to contact the raw materials, severely limiting the mixing process and affecting the removal of bubbles.
[0005] For example, in traditional equipment, negative pressure exhaust is mostly used in conjunction with stirring to remove air bubbles from the raw materials. In some traditional equipment, the stirring structure is also adjusted for height to ensure more thorough and complete mixing. However, the lifting range of traditional equipment is fixed and cannot be adjusted according to the volume of raw materials in the reactor. As a result, only part of the stirring structure is submerged in the mixture. During the lifting adjustment process, the lifting stroke is limited, and the mixing effect is still not good. Utility Model Content
[0006] This utility model discloses a defoaming structure for mixing raw materials in film production, aiming to solve the technical problem that traditional defoaming structures for mixing raw materials in film production use have a fixed and simple mixing method, which cannot be adjusted according to the amount of raw materials to be mixed. This results in some parts of the mixing structure not being able to contact the raw materials, severely restricting the mixing process and affecting the discharge of bubbles.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A defoaming structure for mixing raw materials in film production includes a vessel body and a top cover mounted on the top of the vessel body. A rotating rod is connected to the inner wall of the vessel body via a bearing. The structure also includes: a lifting and mixing mechanism disposed on the outer wall of the rotating rod; and a range control mechanism including a mounting base disposed at the bottom of the top cover, an adjusting disc hinged to the bottom of the mounting base, an adjusting screw threaded to one side of the top outer wall of the top cover, a knob at the top of the adjusting screw, and a movably connected bottom end to one side of the top outer wall of the adjusting disc. An elongated hole is formed at the center of the top outer wall of the adjusting disc, and the rotating rod passes through the inner wall of the elongated hole.
[0009] In this solution, the deflection angle of the adjustment plate can be adjusted through the set range adjustment mechanism, thus changing the overall height difference of the adjustment plate. The height difference is connected to the lifting and mixing mechanism to change the overall stroke of the lifting and mixing mechanism. In actual use, turning the knob will rotate the adjustment screw, and the rotation of the adjustment screw will drive one side of the adjustment plate to rise and fall. The adjustment method is flexible, highly targeted, and has a better defoaming effect.
[0010] In a preferred embodiment, a mounting bracket is provided on the top outer wall of the top cover, and a motor is provided on the top of the mounting bracket. The rotating rod is connected to the output end of the motor. The lifting and mixing mechanism includes two connecting sleeves disposed on the outer wall of the rotating rod. Equally spaced stirring support rods are installed on the outer walls of the two connecting sleeves. The top ends of the three support rods are connected to the same movable disk. A support column is provided at the top of the movable disk at an off-center position. A limiting groove is opened on the outer wall of the rotating rod. Two limiting sliders are provided on the inner side of the movable disk. The two limiting sliders are respectively adapted to the two limiting grooves. A fixed sleeve is connected to the bottom end of the rotating rod. A movable sleeve is connected to the bottom of one of the connecting sleeves. The fixed sleeve is slidably connected to the inner wall of the movable sleeve. A return spring is provided on the inner wall of the movable sleeve. The bottom end of the return spring is connected to the top end of the fixed sleeve.
[0011] With the lifting and mixing mechanism, the lifting and mixing operation can be performed at a suitable stroke after the range control mechanism is adjusted. Specifically, when the motor drives the rotating rod to rotate, the movable plate on the outer wall of the rotating rod will rotate together. The rotation of the movable plate will also drive the support column installed on its top to support and cooperate at the bottom of the adjusting plate. During this process, the return spring located between the movable sleeve and the fixed sleeve provides support force. Due to the height difference at the bottom of the adjusting plate, the support column pressing the movable plate will also drive the stirring rod to lift and lower according to this height difference, making the mixing more thorough and comprehensive.
[0012] As described above, a defoaming structure for mixing raw materials in film production includes a vessel body and a top cover mounted on the top of the vessel body. A rotating rod is connected to the inner wall of the vessel body via a bearing. The structure also includes: a lifting and mixing mechanism disposed on the outer wall of the rotating rod; and a range control mechanism comprising a mounting base disposed at the bottom of the top cover, an adjusting disc hinged to the bottom of the mounting base, an adjusting screw threaded to one side of the top outer wall of the top cover, a knob at the top of the adjusting screw, and a movably connected bottom end to one side of the top outer wall of the adjusting disc. An elongated hole is formed in the center of the top outer wall of the adjusting disc, and the rotating rod passes through the inner wall of the elongated hole. The defoaming structure for mixing raw materials in film production provided by this utility model has the technical effect of improving the targeting of adjustment and the comprehensiveness of defoaming.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0019] The defoaming structure for mixing raw materials in film production disclosed in this utility model is mainly applied to scenarios where traditional defoaming structures for mixing raw materials in film production use a fixed and simple stirring method, which cannot be adjusted according to the amount of raw materials to be mixed. This results in some parts of the stirring structure not being able to contact the raw materials, severely restricting the stirring process and affecting the discharge of bubbles.
[0020] Reference Figure 1 , Figure 2 and Figure 3 A defoaming structure for mixing raw materials in film production includes a vessel body 1 and a top cover 7 installed on the top of the vessel body 1. A rotating rod 10 is connected to the inner wall of the vessel body 1 via a bearing. The structure also includes: a lifting mixing mechanism: the lifting mixing mechanism is installed on the outer wall of the rotating rod 10; and a range control mechanism: the range control mechanism includes a mounting base 14 installed at the bottom of the top cover 7. The bottom of the mounting base 14 is connected to an adjusting plate 15 via a hinge. An adjusting screw 13 is threadedly connected to one side of the top outer wall of the top cover 7. A knob 12 is provided at the top of the adjusting screw 13. The bottom end of the adjusting screw 13 is movably connected to one side of the top outer wall of the adjusting plate 15. An elongated hole is opened at the center of the top outer wall of the adjusting plate 15, and the rotating rod 10 is installed through the inner wall of the elongated hole.
[0021] Specifically, the deflection angle of the adjustment plate 15 can be adjusted by the range adjustment mechanism, thus changing the overall height difference of the adjustment plate 15. The height difference is connected to the lifting and mixing mechanism to change the overall stroke of the lifting and mixing mechanism. In actual use, turning the knob 12 will rotate the adjustment screw 13. The rotation of the adjustment screw 13 will drive one side of the adjustment plate 15 to rise and fall. The adjustment method is flexible and highly targeted.
[0022] It should be noted that the movable connection at the connection between the adjusting screw 13 and the adjusting plate 15 specifically means that it can not only be slidably adjusted, but also has a bearing connection structure, which ensures that the adjusting screw 13 will not interfere with the adjusting plate 15 when it rotates. At the same time, the connection position of the sliding adjustment can avoid connection interference caused by the deflection process of the adjusting plate 15.
[0023] In addition, a locking device such as a locking nut or a specially designed locking washer is installed at the threaded connection between the adjusting screw 13 and the top cover 7. After adjustment, there will be no air leakage at this point, thus avoiding the problem of poor sealing and failure to achieve negative pressure exhaust in the later stage.
[0024] The outer wall of the vessel body 1 is provided with a feed pipe 2, the bottom of the vessel body 1 is provided with a discharge pipe 4, and the outer wall of the vessel body 1 is also provided with a negative pressure exhaust pipe 3. The negative pressure exhaust pipe 3 can be used to maintain the vessel body 1 in a negative pressure state during the mixing process.
[0025] Reference Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, a mounting bracket 5 is provided on the top outer wall of the top cover 7, and a motor 6 is provided on the top of the mounting bracket 5. The rotating rod 10 is connected to the output end of the motor 6. The lifting and mixing mechanism includes two connecting sleeves 18 provided on the outer wall of the rotating rod 10. Stirring support rods 11 are installed on the outer walls of the two connecting sleeves 18 at equal intervals. The top ends of the three support rods are connected to the same movable disk 9. A support column 16 is provided at the top of the movable disk 9 at an off-center position. A limiting groove is opened on the outer wall of the rotating rod 10. Two limiting sliders are provided on the inner side of the movable disk 9. The two limiting sliders are respectively adapted to the two limiting grooves. A fixed sleeve 20 is connected to the bottom end of the rotating rod 10. A movable sleeve 19 is connected to the bottom of one of the connecting sleeves 18. The fixed sleeve 20 is slidably connected to the inner wall of the movable sleeve 19. A return spring 21 is provided on the inner wall of the movable sleeve 19. The bottom end of the return spring 21 is connected to the top end of the fixed sleeve 20.
[0026] Specifically, through the set lifting and mixing mechanism, the lifting and mixing operation can be performed with a suitable stroke after the range control mechanism is adjusted. Specifically, when the motor 6 drives the rotating rod 10 to rotate, the movable disk 9 on the outer wall of the rotating rod 10 will rotate together. The rotation of the movable disk 9 will also drive the support column 16 installed on its top to support and cooperate at the bottom of the adjusting disk 15. During this process, the return spring 21 located between the movable sleeve 19 and the fixed sleeve 20 provides support force. Due to the height difference at the bottom of the adjusting disk 15, the support column 16 pressing the movable disk 9 will also drive the stirring support rod 11 to lift and lower according to this height difference.
[0027] Reference Figure 2 and Figure 3 In a preferred embodiment, the bottom end of the rotating rod 10 is connected to equidistantly distributed tilting plates 17, which are close to the bottom of the vessel body 1.
[0028] Reference Figure 1 and Figure 2 In a preferred embodiment, a base frame 8 is provided on both outer walls of the vessel body 1.
[0029] Working principle: During use, the raw materials to be mixed and defoamed are introduced into the vessel body 1 through the feed pipe 2. Then, the knob 12 is rotated according to the amount of raw materials in the vessel body 1 to change the height difference at the bottom of the adjustment plate 15. After adjustment, the negative pressure exhaust pipe 3 is connected to the air pump to ensure that the inside of the vessel body 1 is in a negative pressure state. Then, the motor 6 is started. The motor 6 drives the rotating rod 10 to rotate the stirring support rod 11. The movable plate 9 on the outer wall of the rotating rod 10 will rotate together. The rotation of the movable plate 9 will also drive the support column 16 installed on its top to rotate at the bottom of the adjustment plate 15. During this process, the return spring 21 provides support force. Due to the height difference at the bottom of the adjustment plate 15, the support column 16 squeezes the movable plate 9 and also drives the stirring support rod 11 to rise and fall according to this height difference to complete the thorough mixing. During this process, the bubbles will be discharged from the negative pressure exhaust pipe 3 under the action of negative pressure. Finally, the defoamed raw materials are discharged from the discharge pipe 4.
[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
