Description

[0002] GPPS diffuser is a plate with light diffusion function made of polystyrene as the base material. It can be used in the backlight module of liquid crystal display, OLED display and other equipment. As a diffusion layer, it can evenly distribute the light, improve the display quality, and reduce the phenomenon of uneven brightness. It can also be used in side light source LED lighting fixtures, such as flat panel lights, advertising light boxes, professional film viewing lights, etc. It is usually used in combination with light guide plates to provide uniform surface light source for lamps, soften the light, reduce glare, and improve lighting effects and visual comfort.

[0003] In the prior art, such as the Chinese patent publication number: CN115257020B, an automatic production line for extrusion, molding, conveying and cutting of GPPS sheets is disclosed, including an extruder unit, a metering unit, a three-roll calender unit, a cooling bracket, a laminating unit, a traction unit, a longitudinal saw unit, a waste edge winding unit and a transverse saw unit.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When in use, the servo motor is started to drive the traction roller located below to rotate.

[0019] 2. When in use, by starting the driving motor, the two wheels are connected by the connecting chain. Then when one wheel rotates, the other wheel will also rotate synchronously, thereby driving the two closed disks to rotate. The closed disk is sleeved on the outside of the feed pipe when rotating. The rotation of the closed disk will drive the reinforcing shaft and the spiral feeding rod to rotate. The outer surfaces of the two spiral feeding rods are tightly attached to the inner walls of the feed pipe and the feed pipe respectively. When they rotate, the injected main material and auxiliary material will enter the corresponding conveying bin and extrusion bin after passing through the feed pipe and the diverter pipe. At this time, the raw materials passing through the diverter pipe and the feed pipe are heated by energizing the heating belt, and the heated raw materials are more easily transported forward.

[0020] 3. During use, since GPPS may be aged by the oxidation of oxygen during processing and use, such as turning yellow and brittle, antioxidants can inhibit this oxidation reaction. By pouring the main material and auxiliary material from two feed bins at the same time, the main material and auxiliary material will be pushed forward under the rotation of the two spiral feeding rods. The two auxiliary materials are respectively transported to the two conveying bins located at the upper and lower positions, while the main material is transported to the extrusion bin located in the middle. Under the continuous feeding action of the two spiral feeding rods, the main material and the auxiliary material will be mixed. The intersection area is the intersection bin. The gap at the outlet of the intersection bin is narrow, and the distance of the gap is the thickness of the extrusion diffusion plate, thereby achieving the mixing of the main material and the auxiliary material during the extrusion process and improving production efficiency.

A traction roller 305 is fixedly connected between the two rotating blocks 304. The traction roller 305 is made of rubber material and is used to convey the plate 5. The outer surfaces of the two traction rollers 305 are in contact with the top and bottom of the plate 5 respectively. A support plate 301 is fixedly connected to the outer surface of one side of the support plate 301 07. A servo motor 306 is arranged on the top of the support plate 307. The output shaft of the servo motor 306 is fixedly connected to one side of one of the rotating blocks 304. The bottom of the extrusion device 101 is fixedly connected to a support assembly 4. The support assembly 4 includes a support frame 401. The top of the support frame 401 is fixedly connected to a mounting frame 402.

[0035] In this embodiment, when in use, the specific implementation method of feeding is as follows: first, the main material is poured into the feed bin 208 connected to the feed pipe 206, and the auxiliary material is poured into the feed bin 208 connected to the diversion pipe 204, and the drive motor 212 is started to rotate its output shaft, thereby driving one of the rotating wheels 211 to rotate. Since the two rotating wheels 211 are connected by the connecting chain 210, when one rotating wheel 211 rotates, the other rotating wheel 211 will also rotate synchronously, thereby driving the two closing disks 213 to rotate. When the closing disks 213 rotate, they are sleeved on the The rotation of the closing disk 213 outside the delivery pipe 205 will drive the reinforcing shaft 214 and the spiral feeding rod 215 to rotate. The outer surfaces of the two spiral feeding rods 215 are tightly attached to the inner walls of the delivery pipe 205 and the feeding pipe 206 respectively. When they rotate, the injected main material and auxiliary material will enter the corresponding conveying bin 103 and extrusion bin 104 after passing through the feeding pipe 206 and the diverter pipe 204. At this time, the heating belt 203 is powered on to heat the raw materials passing through the diverter pipe 204 and the feeding pipe 206, and the heated raw materials are easier to be transported forward.

[0037] In this embodiment, when the GPPS diffuser is used, the main raw material used is general-purpose polystyrene, and the auxiliary materials are light diffusers and antioxidants. The light diffuser changes the propagation path of light in the plate 5. When light enters the GPPS diffuser containing the light diffuser, it will be refracted, reflected and scattered on the surface of the light diffuser particles, so that the light becomes soft and uniform, and the glare is reduced. In addition, since GPPS may be aged by oxidation of oxygen during processing and use, such as yellowing and brittleness, the antioxidant can inhibit this oxidation reaction. By mixing the main material and the auxiliary material together, the light diffuser can be used to change the propagation path of light in the plate 5. When poured in from the two feeding bins 208 respectively, the two spiral feeding rods 215 rotate, pushing the main material and the auxiliary material forward, and the two auxiliary materials are respectively conveyed to the two conveying bins 103 located at the upper and lower positions, while the main material is conveyed to the extrusion bin 104 located in the middle position. Under the continuous feeding action of the two spiral feeding rods 215, the main material and the auxiliary material will intersect and mix, and the intersection area is the intersection bin 102. The gap at the outlet of the intersection bin 102 is narrow, and the distance of the gap is the thickness of the extrusion diffusion plate, thereby achieving the mixing of the main material and the auxiliary material during the extrusion process, thereby improving production efficiency.

[0038] The use method and working principle of the device: When the GPPS diffuser is processed, the main raw material used is general-purpose polystyrene, and the auxiliary materials are light diffusers and antioxidants. The function of the light diffuser is to change the propagation path of light in the plate 5. When the light enters the GPPS diffuser containing the light diffuser, it will be refracted, reflected and scattered on the surface of the light diffuser particles, so that the light becomes soft and uniform, and the glare is reduced. In addition, since GPPS may be aged by oxidation of oxygen during processing and use, such as yellowing and brittleness, the antioxidant can inhibit this oxidation reaction. By pouring the main material and the auxiliary material from the two feeding bins 208 at the same time, the main material and the auxiliary material will be rotated by the two spiral feeding rods 215. The materials are pushed forward, and the two auxiliary materials are respectively conveyed to the two conveying bins 103 located at the upper and lower positions, while the main material is conveyed to the extrusion bin 104 located in the middle position. Under the continuous feeding action of the two spiral feeding rods 215, the main material and the auxiliary material will be intersected and mixed. The intersection area is the intersection bin 102. The gap at the outlet of the intersection bin 102 is narrow, and the distance of the gap is the thickness of the extrusion diffusion plate. When in use, the specific implementation method of feeding is as follows: first, the main material is poured into the feed bin 208 connected to the feed pipe 206, and the auxiliary material is poured into the feed bin 208 connected to the diverter pipe 204. By starting the drive motor 212, the output shaft is rotated, thereby driving one of the wheels 211 to rotate. Since the two wheels 211 are connected by a chain If the two rotary wheels 210 are connected, when one rotary wheel 211 rotates, the other rotary wheel 211 will also rotate synchronously, thereby driving the two closed disks 213 to rotate. The closed disk 213 is sleeved on the outside of the conveying pipe 205 when rotating. The rotation of the closed disk 213 will drive the reinforcing shaft 214 and the spiral feeding rod 215 to rotate. The outer surfaces of the two spiral feeding rods 215 are tightly attached to the inner walls of the conveying pipe 205 and the feeding pipe 206 respectively. When they rotate, the injected main material and auxiliary material will enter the corresponding conveying bin 103 and extrusion bin 104 after passing through the feeding pipe 206 and the shunt pipe 204. At this time, the raw materials passing through the shunt pipe 204 and the feeding pipe 206 are heated by energizing the heating belt 203, and the heated raw materials are heated. The material is more easily conveyed forward. When in use, the sheet 5 extruded by the extrusion device 101 is very brittle. The sheet 5 will be placed flat on the top of the support assembly 4. By sleeves of multiple movable rollers 404 on the outside of the fixed rod 403, the inner wall of the movable roller 404 and the fixed rod 403 can rotate flexibly. The outer material of the movable roller 404 is hard rubber. The contact between the movable roller 404 and the sheet 5 will protect the surface of the sheet 5, so that the sheet 5 will not be scratched. The mounting frame 402 and the support frame 401 support the extrusion device 101 and the sheet 5. By making the sheet 5 reach the upper surface of the traction roller 305 located below, the servo motor 306 is started to rotate its output shaft, thereby driving the traction roller 305 located below to rotate.When the plate 5 contacts the traction roller 305, the traction speed it receives is instantly accelerated. The material of the GPPS diffuser plate is brittle, and the sudden tensile force will easily cause it to crack or break. However, since the support tube 313 and the two buffer rods 310 are composed of a strong spring 309 and a slightly elastic buffer elastic block 312, when the plate 5 is pulled, the tensile force and impact force it receives will be absorbed by the elastic mechanism composed of the strong spring 309 and the buffer elastic block 312.
