Embodiments

[0030] Please refer to Figures 1-4 A roll-shaped polarizing plate unloading machine printing device, comprising a base 1, the top of the base 1 is provided with an unloading printing mechanism 2, the unloading printing mechanism 2 comprises two feeding cylinders 21, the feeding cylinders 21 are installed on one side of the top end of the base 1 for moving the roll-shaped polarizing plate to the top of the base 1 and printing; one side of the feeding cylinder 21 is provided with a cutting piece 22, the cutting piece 22 is installed on the top of the base 1, and the cutting piece 22 is used for cutting the roll-shaped polarizing plate. The unloading printing mechanism 2 further comprises a printing piece 23, the printing piece 23 is installed on the other side of the top end of the base 1, and the printing piece 23 is used for printing the roll-shaped polarizing plate. One end of the roll-shaped polarizing plate is moved to one side of the feeding cylinder 21, so as to pass below the first feeding cylinder 21 and above the second feeding cylinder 21. The two feeding cylinders 21 rotate in different directions, so as to push the roll-shaped polarizing plate to the top of the base 1, and ensure that the end thereof is attached to the conveying belt.

[0031] Subsequently, the conveying belt moves clockwise, and drives the roll-shaped polarizing plate to move below the support 31. In this process, the top end of the roll-shaped polarizing plate is in contact with the roller at the bottom end of the flattening plate 33, and the bottom end thereof is attached to the top end of the conveying belt. When the roll-shaped polarizing plate moves to the required length, the cutting piece 22 starts to cut, and the printing piece 23 is responsible for printing the roll-shaped polarizing plate placed flat on the top of the conveying belt.

[0032] In addition, after the printing is completed, the conveying belt continues to rotate, and the printed roll-shaped polarizing plate is conveyed to the inside of the collecting box 35.

[0033] Further, the leveling mechanism 3 is arranged on the top of the base 1 to center the roll polarizer, and the leveling mechanism 3 comprises two inner plates 38. The bottom end of the inner plate 38 is slidably connected with the top end of the base 1, and one side of the inner plate 38 is provided with an outer plate 36. The bottom end of the outer plate 36 is fixedly connected with the top end of the base 1, and a plurality of threaded grooves are formed in the middle of the outer plate 36. The inner wall of the threaded groove is threadedly connected with a threaded rod 37, and one end of the threaded rod 37 is rotatably connected with the side wall of the inner plate 38. The leveling mechanism 3 further comprises a pressing plate 33, and the bottom end of the pressing plate 33 is embedded with a roller. The top of the pressing plate 33 is provided with a support 31, and the bottom end of the support 31 is connected with the top end of the base 1. A threaded groove is formed in the top of the support 31, and a threaded rod 32 is threadedly connected in the threaded groove. The bottom end of the threaded rod 32 is rotatably connected with the top end of the pressing plate 33. Two slide grooves 34 are formed in the inner wall of the support 31, and the two ends of the pressing plate 33 are fixedly connected with slide blocks. The slide blocks are slidably connected with the inner wall of the slide grooves 34. One end of the inner plate 38 is provided with a material collecting box 35, and one side of the material collecting box 35 is connected with one side of the base 1. A conveying belt is installed in the middle of the base 1. In order to stably convey the roll polarizer to the top of the conveying belt for printing, the worker needs to first rotate the threaded rod 32 clockwise according to the thickness of the roll polarizer, so that it moves downward of the support 31, and then pushes the pressing plate 33 to approach the position of the base 1.

[0034] In this way, when the roll polarizer passes through the support 31, the extrusion effect between the conveying belt and the pressing plate 33 can flatten it, ensuring the stability of subsequent printing. In addition, the worker also needs to rotate the threaded rods 37 on both sides according to the width difference of the roll polarizer.

[0035] By rotating the threaded rod 37 clockwise, the inner plate 38 can be pushed to move to the middle of the base 1, and the movement distance of the two inner plates 38 needs to be consistent to adapt to roll polarizers of different widths. This adjustment can make the roll polarizer more stable during movement, reduce deviation, and thus ensure that the printed pattern is clear and stable.

[0036] It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. It is also possible in the present disclosure that steps can be executed in different sequence where is practical and / or certain steps can be modified, eliminated, or added.
