Description

Technical Field

[0001] This utility model belongs to the field of optical material processing equipment technology, specifically relating to a high color gamut optical diffusion plate production device. Background Technology

[0002] With the rapid development of display technology, high color gamut optical diffusion plates, as key components for improving the color saturation, uniformity, and visual effects of display images, are increasingly widely used in fields such as LCD monitors and LED lighting. Their performance directly affects the display quality of end products, thus placing stringent requirements on the precision and stability of manufacturing processes and equipment.

[0003] The material stirring and dispersing function of the optical diffuser plate production equipment is limited, making it difficult to effectively break up internal agglomerated particles. This results in localized abnormal light transmittance within the plate, failing to meet the stringent standard of uniform light diffusion for high color gamut optical diffusers. This phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content

[0004] The purpose of this invention is to address the problems mentioned in the background art in existing high color gamut optical diffusion plate production equipment.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high color gamut optical diffusion plate production device, including an extrusion chamber, with two sets of motor-driven meshing screws on one side, a feed frame fixed to the top of the extrusion chamber, a drive motor on one side, the output end of the motor connected to a first dispersion roller, the first dispersion roller being linked to a second pulley and a second dispersion roller through a first pulley and a first belt body, and the two rollers meshing.

[0006] This utility model further illustrates that two sets of connecting plates with weight sensors are hinged inside the feeding frame, and a hydraulic cylinder is hinged between the connecting plates and the inner wall of the feeding frame.

[0007] This utility model further explains that a third pulley is provided outside both the first dispersing roller and the second dispersing roller, and the fourth pulley is linked through the second belt body.

[0008] This utility model further illustrates that the fourth pulley connects to the connecting rod with the striking block.

[0009] This utility model further illustrates that the slide rod is fixed to the inner wall of the feed frame by a mounting plate.

[0010] This utility model further illustrates that the slide rod slidably connects to the screen, and a return spring is sleeved between the screen and the mounting plate.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0012] Equipped with a first dispersing roller, a second dispersing roller, and a weight sensor, the material is fed from the top of the feeding frame and first falls onto the hinged connecting plate. The weight sensor monitors the weight in real time. When the weight reaches a preset value, the signal triggers the hydraulic cylinder to push the connecting plate downward, causing the material to fall into the feeding frame. At this time, the drive motor drives the second pulley through the first belt pulley and the first belt body, causing the first dispersing roller and the second dispersing roller to mesh and rotate in opposite directions, shearing and dispersing the material and breaking up agglomerated particles.

[0022] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-7 This utility model provides a technical solution: a high color gamut optical diffusion plate production device, including an extrusion chamber 1. Two sets of motors 2 are installed on one side of the extrusion chamber 1. The output ends of the two sets of motors 2 are connected to screws 3 extending into the extrusion chamber 1, and the two sets of screws 3 are meshed together. A feeding frame 4 is fixedly connected to the top of the extrusion chamber 1. A drive motor 5 is installed on one side of the feeding frame 4. The output end of the drive motor 5 is connected to a first dispersing roller 6 extending into the feeding frame 4. A first pulley 7 is fixedly connected to the outer surface of one end of the first dispersing roller 6 outside the feeding frame 4. A first belt body 8 is sleeved on the outside of one end of the first pulley 7. A second pulley 9 is connected to the other end of the first belt body 8. A second dispersing roller 10 extending into the feeding frame 4 is fixedly connected inside the second pulley 9. The first dispersing roller 6 and the second dispersing roller 10 are meshed together.

[0024] When the material enters the feed box 4, the drive motor 5 is started. The output end of the drive motor 5 drives the first pulley 7 to rotate. The first belt body 8, which is sleeved with the first pulley 7, can drive the second pulley 9 to rotate synchronously, so that the material of the first dispersing roller 6 and the second dispersing roller 10 can be stirred and dispersed to prevent the material from clumping.

[0025] The inside of the feed frame 4 is hinged with two sets of connecting plates 11, and a weight sensor 12 is provided below the connecting plate 11. The top of the connecting plate 11 is hinged with the inside of the feed frame 4 with a hydraulic cylinder 13.

[0026] When the material enters the feeding frame 4, it first reaches the top of the connecting plate 11. The weight sensor 12 is set with a certain value. When the weight reaches a certain value, the signal is transmitted to the hydraulic cylinder 13. The hydraulic cylinder 13 can push the connecting plate 11 to move downward, so that the material falls into the first dispersing roller 6 and the second dispersing roller 10 for dispersion, realizing quantitative feeding, and at the same time, placing foreign objects into the interior of the feeding frame 4.

[0027] The first dispersing roller 6 and the second dispersing roller 10 are both fixedly connected to the outside of a third pulley 14. The outer surface of the third pulley 14 is fixedly connected to a second belt body 15. One end of the second belt body 15 is connected to a fourth pulley 16. The inside of both sets of fourth pulleys 16 is fixedly connected to a connecting rod 17. The outer surface of the connecting rod 17 is fixedly connected to a striking block 18.

[0028] When the first dispersing roller 6 and the second dispersing roller 10 rotate synchronously, they can drive the third pulley 14 to rotate, so that the second belt body 15 drives the fourth pulley 16 to rotate, the connecting rod 17 fixedly connected to the fourth pulley 16 can rotate, and the striking block 18 fixedly connected to the connecting rod 17 can rotate.

[0029] Mounting plates 19 are fixedly installed on both inner walls of the feed frame 4. A sliding rod 20 is fixedly connected between the two sets of mounting plates 19. A screen 21 is slidably connected to the outside of the sliding rod 20. A return spring 22 sleeved on the outer surface of the sliding rod 20 is fixedly connected between the mounting plate 19 and the screen 21.

[0030] The screen 21 is located below the striking block 18. The screen 21 is slidably connected to the slide bar 20. When the striking block 18 rotates, it can push the screen 21 and the return spring 22 to press down. After the striking block 18 and the screen 21 are no longer in contact, the return spring 22 can drive the screen 21 to return to its original position, thereby achieving the purpose of rapid screening of materials.

[0031] Working principle: After the material is fed from the top of the feeding frame 4, it first falls on the hinged connecting plate 11. The weight sensor 12 monitors the weight in real time. When the preset value is reached, the signal triggers the hydraulic cylinder 13 to push the connecting plate 11 to tilt downward, so that the material falls into the feeding frame 4. At this time, the drive motor 5 drives the second pulley 9 through the first pulley 7 and the first belt body 8, so that the first dispersing roller 6 and the second dispersing roller 10 mesh and rotate in opposite directions to shear and disperse the material and break up the agglomerated particles. When the dispersing roller rotates, it drives the fourth pulley 16 through the third pulley 14 and the second belt body 15, which drives the connecting rod 17 and the eccentric striking block 18 to rotate. The striking block 18 periodically hits the screen 21, causing it to slide on the slide rod 20 and compress the return spring 22, forming high-frequency vibration to prevent the screen 21 from clogging. After the qualified material passes through the screen 21, it falls into the extrusion chamber 1 for heating and finally extrusion molding.
