Description
Technical Field
[0001] This utility model relates to the field of polarizer processing technology, specifically to a polarizer adhesive mixing device. Background Technology
[0002] With the widespread application of electronic devices such as liquid crystal displays (LCDs) and organic light-emitting diode displays (OLEDs), the market demand for polarizers, as an important component, continues to grow. The production process of polarizers involves the composite of various materials, among which adhesives play a key bonding role, ensuring that the materials of each layer can be firmly bonded to achieve good optical and physical properties of the polarizer.
[0003] The adhesive needs to be thoroughly stirred before use to achieve a uniform mixing state. This is because the adhesive for polarizing film is usually a composite system composed of a variety of polymers and additives (such as curing agents and plasticizers). If the stirring is not uniform, the components will be unevenly distributed, which will affect the adhesive's bonding strength, curing speed, transparency and other key performance indicators, and ultimately have an adverse effect on the quality of the polarizing film.
[0004] In existing production scenarios, commonly used mixing devices include simple mechanical mixers, such as paddle mixers and turbine mixers. These mixers use a motor to drive the mixing blades to rotate inside the adhesive container, relying on the shearing and pushing action of the blades to achieve mixing. However, during the mixing process, traditional paddle or turbine mixers often result in insufficient mixing of the adhesive materials due to their relatively simple mixing method. This affects the overall uniformity of the final adhesive, which in turn affects the bonding effect and quality stability of the polarizer. Therefore, we propose an adhesive mixing device for polarizers. Utility Model Content

The conical hopper helps the mixed material enter the collection bucket more effectively. Activating the auxiliary hydraulic cylinder causes the crossbar to slide outside the limit rod, simultaneously moving the collection bucket up and down, thus improving the device's efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1 - Figure 6 This utility model provides a technical solution:
[0028] A polarizer adhesive mixing device includes a frame 1, with casters 2 at the bottom of the frame 1, four sets of casters 2, a vertical plate 3 fixedly installed on one side of the top of the frame 1, and a controller 4 fixedly installed on the outside of the vertical plate 3.
[0029] In one embodiment of this utility model, a stirring assembly 5 is provided on the frame 1. The stirring assembly 5 includes a hinge seat 51. The hinge seat 51 is fixedly installed on the other side of the top of the frame 1. A hinge rod 52 is rotatably installed inside the top of the hinge seat 51. Two sets of hinge seats 51 and hinge rods 52 are provided. The two sets of hinge rods 52 are respectively fixedly installed on the outer side of the bottom end of the stirring tank 53. The fixed end of the servo hydraulic cylinder 54 is hinged to the outer side of the top of the vertical plate 3. The piston end of the servo hydraulic cylinder 54 is hinged to the outer side of the top of the stirring tank 53. A round cover 55 is snapped onto the top of the stirring tank 53. First, feed is fed into the stirring tank 53 through the feed inlet 517 provided on the round cover 55. Material is input into the feed inlet (the feed hopper and feed valve are connected at the feed inlet 517, which will not be described in detail here). When the servo hydraulic cylinder 54 is activated, its piston end pulls the top of the mixing drum 53 to move, causing the hinge rod 52 to rotate within the hinge seat 51, thereby allowing the mixing drum 53 to swing, resulting in better mixing of the material within the mixing drum 53. A stirring motor 56 is fixedly installed at the center of the top of the round cover 55. A center rod 57 is fixedly installed on the outer side of the output shaft at the bottom of the stirring motor 56. A stirring paddle 58 is fixedly installed on the outer side of the center rod 57. A stirring rod 59 is fixedly installed on the stirring paddle 58. In addition, there are three sets of stirring paddles 58, and the three sets of stirring paddles 59 are... 8. The stirring rods 58 and 59 are arranged in an evenly spaced circular array inside the mixing tank 53, with the center of the circular cross-section of the central rod 57 as the array center. Multiple sets of stirring rods 59 are provided on each set of stirring paddles 58 to improve the mixing effect. A T-shaped discharge box 510 is fixedly installed on the outer bottom of the mixing tank 53, and the T-shaped discharge box 510 is connected to the inside of the mixing tank 53. Activating the stirring motor 56 on the round cover 55 rotates the central rod 57, which in turn rotates the stirring paddles 58 and the multiple sets of stirring rods 59 on the stirring paddles 58, thus better mixing the raw materials of the adhesive body. A servo fluid is fixedly installed on the outer periphery of the top of the round cover 55. The pressure rod 511 and the piston end of the servo hydraulic rod 511 are fixedly installed with a piston rod 512. The bottom of the piston rod 512 is fixedly connected to the top center of the arc plate 513. The arc plate 513 and the arc opening of the T-shaped discharge box 510 are on the same vertical plane. The bottom end of the arc plate 513 is set as an inclined surface 514. When the servo hydraulic rod 511 is started, it works with the piston rod 512 to drive the arc plate 513 to move up and down. With the help of the inclined surface 514, the arc plate 513 can move downward better with less resistance. When the arc plate 513 moves upward, the arc opening of the T-shaped discharge box 510 is not blocked by the arc plate 513, and the material can be discharged.When the arc-shaped plate 513 moves downward, it can seal the arc-shaped opening. A conical baffle 515 is engaged with the bottom of the round cover 55. The inner side of the bottom end of the conical baffle 515 slides against the arc-shaped outer wall of the piston rod 512. Simultaneously, the conical baffle 515 can clean impurities from the outer side of the upward-moving piston rod 512. An arc-shaped plate 516 is fixedly installed on the outer side of the bottom end of the central rod 57. A feed inlet 517 is provided on the round cover 55. The central rod 57 drives the arc-shaped plate 516 to rotate, better discharging the mixed material. Furthermore, five sets of arc-shaped plates 516 are arranged in a circular array at equal intervals around the center of the circular cross-section of the central rod 57 at the bottom of the mixing tank 53, thus improving material discharge.
[0030] In one embodiment of this utility model, an auxiliary component 6 is provided on the frame 1. The auxiliary component 6 includes a triangular block 61. The triangular block 61 is fixedly installed on the inner side of the end of the T-shaped discharge box 510 away from the mixing tank 53. The triangular block 61 and the T-shaped discharge box 510 are provided with corresponding discharge holes 62. Multiple sets of discharge holes 62 are provided, and the multiple sets of discharge holes 62 are linearly arrayed at equal intervals, thereby improving the discharge effect. In addition, an auxiliary hydraulic cylinder 63 is fixedly installed on the upper surface of the bottom end of the frame 1. The piston end of the auxiliary hydraulic cylinder 63 is fixedly connected to the bottom center of the cross 64. A limit rod 65 is fixedly installed on the upper surface of the bottom end of the frame 1. The end of the cross 64 away from its center slides against the outside of the limit rod 65. Three sets of limit rods 65 are provided. This makes the movement of the cross 64 more stable. In addition, the top of the cross 64 is engaged with a collection bucket 66, and the inner side of the top of the collection bucket 66 is engaged with a conical hopper 67. The conical hopper 67 is located directly below the discharge hole 62. Furthermore, the mixed material is better discharged from the discharge hole 62 to the conical hopper 67 on the collection bucket 66 with the help of the triangular block 61. The conical hopper 67 makes the mixed material enter the collection bucket 66 better. The auxiliary hydraulic cylinder 63 is activated, and the movement of the cross 64 drives the collection bucket 66 engaged at the top to move up and down better. At the same time, the cross 64 slides outside the limit rod 65, making the movement of the collection bucket 66 more stable, thereby improving the efficiency of the device. The top of the T-shaped discharge box 510 is engaged with a rectangular cover 68.
[0031] All electrical components mentioned in this application are electrically connected to the controller 4 and the 220V mains power. The controller 4 is a conventional and known device that can control the servo hydraulic cylinder 54, the stirring motor 56, the servo hydraulic rod 511, and the auxiliary hydraulic cylinder 63. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.
[0032] Working principle: First, material is fed into the mixing drum 53 through the feed inlet 517 on the round cover 55. When the servo hydraulic cylinder 54 is activated, its piston pulls the top of the mixing drum 53, causing the hinge rod 52 to rotate within the hinge seat 51. This allows the mixing drum 53 to swing, resulting in better mixing of the material within the mixing drum 53. Then, the stirring motor 56 on the round cover 55 is activated, driving the central rod 57 to rotate. The central rod 57 then drives the outer stirring paddle 58 and the multiple sets of stirring rods 59 on the stirring paddle 58 to rotate, thereby better mixing the raw materials of the adhesive body. The servo hydraulic rod 511, in conjunction with the piston rod 512, drives the arc plate 513 to move up and down. With the help of the inclined surface 514, the arc plate 513 can move downward more effectively with less resistance. When the arc plate 513 moves upward, the arc opening of the T-shaped discharge box 510 is not blocked by the arc plate 513, and the material can be discharged. When the arc plate 513 moves downward, it can block the arc opening. At the same time, the conical baffle 515 can clean the impurities on the outside of the piston rod 512 moving upward. The arc plate 516 is driven to rotate by the central rod 57, which can better discharge the mixed material.
[0033] Furthermore, the mixed material, aided by the triangular block 61, is better discharged from the discharge hole 62 to the conical hopper 67 on the collection bucket 66. The conical hopper 67, in conjunction with the material, allows the mixed material to enter the collection bucket 66 more effectively. The auxiliary hydraulic cylinder 63 is activated, and the cross 64 moves, causing the collection bucket 66, which is engaged at the top, to move up and down more effectively. At the same time, the cross 64 slides outside the limit rod 65, making the movement of the collection bucket 66 more stable, thereby improving the efficiency of the device.
[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
