Description

Technical Field

[0001] This invention relates to the field of polarizer production technology, and in particular to a polarizer drying apparatus. Background Technology

[0002] Currently, Chinese utility model application number 202022241300.2 discloses a rapid drying device for polarizing film ink marking. Although it can achieve all-round hot air drying of polarizing films on the conveyor line, improve the drying efficiency of polarizing film ink marking, and thus improve the production efficiency of polarizing films, water stains remain on the upper and lower surfaces of the polarizing films after cleaning. The water stains on the polarizing films need to be removed in the drying zone. During the process of removing water stains, the air pressure applied by the upper and lower air knives in the drying zone and the angle between the air outlet and the polarizing film are different, resulting in differences in the force applied to the upper and lower surfaces of the polarizing film. When the difference is too large, it is easy to cause the polarizing film to stagnate, tilt, or stop moving. Summary of the Invention

Detailed Implementation

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1 , Figure 2 and Figure 4 This embodiment provides a polarizer drying device, including a conveying component 1, a drying component 2 and a pressing component 3. The conveying component 1 includes a conveying roller 11 and a first support plate 12, with the two ends of the conveying roller 11 rotatably connected to the first support plate 12.

[0028] In this preferred embodiment, one or more sets of conveyor rollers 11 are arranged in parallel, and the polarizer is placed on the conveyor rollers 11. When the conveyor rollers 11 rotate, they can drive the polarizer to move.

[0029] The air drying assembly 2 includes a support column 21, an air blowing head 22, and an air inlet pipe 23. The two ends of the air blowing head 22 are fixedly connected to the support column 21, and two air blowing heads 22 are provided, which are respectively provided on both sides of the conveyor roller 11. The air blowing port on the air blowing head 22 faces the conveyor roller 11, and the air blowing head 22 is connected to one end of the air inlet pipe 23.

[0030] In this preferred embodiment, the support column 21 can provide fixed support for the air blowing head 22. The existing fan is connected to the other end of the air inlet pipe 23. When the fan is working, it pumps air into the air inlet pipe 23 and blows the air out through the air blowing head 22. Since the air blowing head 22 is symmetrically arranged on the upper and lower sides of the polarizer and the air blowing port on the air blowing head 22 faces the polarizer, it can ensure that the air pressure of the air knife acts on both sides of the polarizer at the same time, and remove water stains from the upper and lower surfaces of the polarizer.

[0031] The pressing assembly 3 includes a rotating column 31 and a second support plate 32. The rotating column 31 is rotatably connected to the second support plate 32. Two sets of rotating columns 31 are provided, and the two sets of rotating columns 31 are parallel to the length direction of the first support plate 12. Each set includes one or more rotating columns 31. The bottom of the rotating column 31 is located in the gap between the conveying rollers 11. The rotating column 31 is positioned above the conveying rollers 11. A limit ring 311 is provided on the rotating column 31, and the bottom cross-section of the limit ring 311 is smaller than the top cross-section.

[0032] In this preferred embodiment, when the polarizer on the conveyor roller 11 passes through the rotating column 31, the rotating column 31 can play a limiting role to prevent the polarizer from becoming skewed or stationary. Furthermore, the limiting ring 311 on the rotating column 31 can apply a positive downward pressure to the polarizer to prevent the air knife from blowing the polarizer up, which would cause the polarizer to become stuck, skewed, or stationary, thus affecting work efficiency.

[0033] Example 2

[0034] Reference Figures 1 to 7 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that...

[0035] The first support plate 12 is hollow inside, the first flywheel 111 is disposed inside the first support plate 12, and the first flywheel 111 is fixedly connected to the conveyor roller 11. The first flywheel 111 is engaged with the first chain 112.

[0036] Preferably, in this embodiment, the first support plate 12 protects the internal first flywheel 111 and first chain 112, and supports the conveyor rollers 11. When one conveyor roller 11 rotates, it drives the first chain 112 to rotate, which in turn drives the other conveyor rollers 11 to rotate. The lower surface of the first support plate 12 can be mounted and fixed to the workbench to maintain a certain height. During assembly, the first support plate 12 can be first pressed... Figure 3 The cross-section shown is cut open, and after the first flywheel 111 and the first chain 112 are installed, the first support plate 12 is welded together.

[0037] Reference Figure 4The second support plate 32 is hollow inside, and the second flywheel 312 is disposed inside the second support plate 32. The second flywheel 312 is fixedly connected to the rotating column 31, and the second flywheel 312 is engaged with the second chain 313.

[0038] Preferably, in this embodiment, the second support plate 32 can protect the internal second flywheel 312 and second chain 313, and also support the rotating column 31. When the rotating column 31 rotates, it drives the second chain 313 to rotate, and in turn drives the other rotating columns 31 to rotate. The outer walls at both ends of the second support plate 32 can be inserted into the sliding grooves, which are parallel to the direction of the conveyor roller 11. The position of the outer walls of the sliding grooves is fixed by existing support rods. When the two second support plates 32 slide horizontally, they can move closer or further apart, adjusting the distance between the two sets of rotating columns 31 to accommodate polarizers of different sizes. During assembly, the second support plate 32 can be first... Figure 3 The cross-section shown is cut open, and after the second flywheel 312 and the second chain 313 are installed, the second support plate 32 is welded together.

[0039] Reference Figure 2 It also includes an adjustment component 4, which includes a through groove 41, a slider 42, a bidirectional lead screw 43, and a sleeve 44. The two ends of the bidirectional lead screw 43 are rotatably connected to the through groove 41, and one end of the bidirectional lead screw 43 passes through the through groove 41. The bidirectional lead screw 43 is threadedly connected to the slider 42. The slider 42 is slidably connected to the inner wall of the through groove 41, and the bottom of the slider 42 is fixedly connected to the sleeve 44. The sleeve 44 is rotatably connected to the top of the rotating column 31.

[0040] Preferably, in this embodiment, the slider 42 can slide on the inner wall of the through groove 41. When the slider 42 slides, it can drive the rotating column 31 to move horizontally through the sleeve 44. There are two sliders 42, corresponding to one of the rotating columns 31 on the two second support plates 32. When the bidirectional lead screw 43 rotates, it can drive the two sliders 42 to move closer or further away from each other, thereby driving the two second support plates 32 to move closer or further away from each other, adjusting the distance between the two sets of rotating columns 31 on the two second support plates 32, so that the rotating columns 31 can adapt to polarizers of different sizes, and play a limiting role for polarizers of different sizes, preventing the polarizers from becoming skewed or stationary.

[0041] Reference Figure 1 and Figure 2 One of the two sets of rotating columns 31 is fixedly connected to a third flywheel 315, and the third flywheel 315 is connected to a third chain 316.

[0042] In this preferred embodiment, one of the two sets of rotating columns 31 is connected by a third chain 316 to provide power for the rotation of the rotating column 31.

[0043] Reference Figure 1 and Figure 2 The drive assembly 5 includes a motor 51, a first drive shaft 52, a first bevel gear 53, a second bevel gear 54, a third bevel gear 55, a fourth bevel gear 56, a second drive shaft 57, and a square rod 58. The motor 51 is fixedly connected to one end of the first drive shaft 52, and the other end of the first drive shaft 52 is fixedly connected to one end of the conveyor roller 11. The first bevel gear 53 is fixedly connected to the first drive shaft 52, and the first bevel gear 53 meshes with the second bevel gear 54. The second bevel gear 54 is fixedly connected to one end of the second drive shaft 57, and the other end of the second drive shaft 57 is slidably connected to the square rod 58. The square rod 58 is fixedly connected to the third bevel gear 55, and the third bevel gear 55 meshes with the fourth bevel gear 56. The fourth bevel gear 56 is fixedly connected to one end of the bidirectional lead screw 43 that passes through the through groove 41.

[0044] In this preferred embodiment, during use, the control motor 51 operates, driving the first drive shaft 52 to rotate. The first drive shaft 52 drives the conveyor rollers 11 to rotate. When one conveyor roller 11 rotates, it drives the first chain 112 to rotate, and in turn drives the remaining conveyor rollers 11 to rotate, causing the polarizers on the conveyor rollers 11 to move. Furthermore, the first drive shaft 52 drives the first bevel gear 53 to rotate, which in turn drives the second bevel gear 54 to rotate. The second bevel gear 54 drives the second drive shaft 57 to rotate, and the second drive shaft 57 drives the square rod 58 and the first chain 112 to rotate. As the three bevel gears 55 rotate, and the square rod 58 can slide in the second drive shaft 57, when the square rod 58 drives the second drive shaft 57 to move upward, the third bevel gear 55 meshes with the fourth bevel gear 56. At this time, the third bevel gear 55 can drive the fourth bevel gear 56 to rotate, and the fourth bevel gear 56 can drive the bidirectional lead screw 43 to rotate. The bidirectional lead screw 43 can drive the two sliders 42 to move closer or further away from each other, and thus drive the two second support plates 32 to move closer or further away from each other, adjusting the distance between the two sets of rotating columns 31 on the two second support plates 32 so that the rotating columns 31 can adapt to polarizers of different sizes.

[0045] Furthermore, when the square rod 58 drives the second drive shaft 57 to move downwards, the third bevel gear 55 disengages from the fourth bevel gear 56, and at this time, the third bevel gear 55 cannot drive the fourth bevel gear 56 to rotate. Preferably, a motor base is placed at the bottom of the motor 51 to provide fixed support for the motor 51.

[0046] Reference Figure 2The second drive shaft 57 is fixedly connected to the fourth flywheel 571, and the rotating column 31 is correspondingly provided with the fifth flywheel 317. The fourth flywheel 571 and the fifth flywheel 317 are meshed with the fourth chain 572.

[0047] In this preferred embodiment, when the second drive shaft 57 rotates, it can drive the fourth flywheel 571 to rotate. The fourth flywheel 571 can drive the fifth flywheel 317 to rotate through the fourth chain 572. The fifth flywheel 317 can drive one of the two sets of rotating columns 31 to rotate, providing power for the rotation of the rotating column 31.

[0048] Reference Figure 2 The second drive shaft 57 is rotatably connected to one end of the fixed rod 573, and the other end of the fixed rod 573 is fixedly connected to the outer wall of the first support plate 12.

[0049] In this preferred embodiment, the fixing rod 573 can provide fixed support for the second drive shaft 57.

[0050] Reference Figure 2 The fourth chain 572 is engaged with the tension flywheel 574, the tension flywheel 574 is rotatably connected to the shaft 575, the two ends of the shaft 575 are fixedly connected to one side of the support frame 576, the other side of the support frame 576 is fixedly connected to one end of the telescopic rod 577, the other end of the telescopic rod 577 is fixedly connected to the support column 21, and a first spring 578 is sleeved on the telescopic rod 577.

[0051] In this embodiment, the preferred method is adjustment. Figure 2 When the distance between the second drive shaft 57 and the rotating column 31 is adjusted, if the distance between the second drive shaft 57 and the rotating column 31 increases, under the action of the elastic force of the first spring 578, the support column 21, the rotating shaft 575, and the tension flywheel 574 will be pushed towards... Figure 2 Moving the chain to the left can tighten the fourth chain 572, thus ensuring transmission between the fourth flywheel 571 and the fifth flywheel 317. Similarly, a new tension flywheel 574 can be installed on the third chain 316 to keep the third chain 316 taut.

[0052] Furthermore, the first drive shaft 52, the conveyor roller 11, and the second drive shaft 57 have the same radial dimensions, and the first bevel gear 53, the second bevel gear 54, the third bevel gear 55, and the fourth bevel gear 56 have the same dimensions. Therefore, the first drive shaft 52, the conveyor roller 11, and the second drive shaft 57 rotate at the same speed. Thus, when the polarizer on the conveyor roller 11 passes through the rotating column 31, the rotating column 31 can limit its movement, preventing the polarizer from becoming skewed or stuck. Moreover, since the rotating column 31 rotates at the same speed as the conveyor roller 11, it can prevent sliding friction between the rotating column 31 and the polarizer, which would cause scratches on the edge of the polarizer. This also prevents the polarizer from being affected when it passes through the rotating column 31, thus providing assistance to the polarizer.

[0053] Reference Figure 6 and Figure 7 The second drive shaft 57 is provided with a locking component 59, which includes a second spring 591, a third spring 592, a movable rod 593, and a fixed plate 594. The second spring 591 is fixedly connected to one end of the square rod 58, and the other end of the second spring 591 is fixedly connected to the second drive shaft 57. The second drive shaft 57 is slidably connected to the movable rod 593. The square rod 58 is provided with a through hole 581 corresponding to the movable rod 593. The movable rod 593 is fixedly connected to the fixed plate 594. The third spring 592 is sleeved on the movable rod 593. One end of the third spring 592 is fixedly connected to the fixed plate 594, and the other end of the third spring 592 is fixedly connected to the second drive shaft 57.

[0054] In this preferred embodiment, when the fixed plate 594 and the movable rod 593 are pulled outward, the fixed plate 594 and the movable rod 593 move against the tension of the third spring 592. When the movable rod 593 disengages from the through hole 581, under the action of the elastic force of the second spring 591, the square rod 58 is pushed upward. The square rod 58 drives the third bevel gear 55 to move upward until the third bevel gear 55 meshes with the fourth bevel gear 56. At this time, the rotation of the third bevel gear 55 can drive the fourth bevel gear 56 to rotate. When the square rod 58 is pressed down, the through hole 581 on the square rod 58 moves to the position of the movable rod 593. Under the action of the tension of the third spring 592, the third spring 592 pulls the fixed plate 594 and the movable rod 593 to move, inserting the movable rod 593 into the through hole 581. At this time, the third bevel gear 55 disengages from the fourth bevel gear 56, and the third bevel gear 55 cannot drive the fourth bevel gear 56 to rotate. Preferably, a motor mount is placed at the bottom of the motor 51 to provide fixed support for the motor 51. The third bevel gear 55 disengages from the fourth bevel gear 56, and the position of the third bevel gear 55 is automatically locked.
