[0032] Embodiment one: refer to Figures 1-8As shown, the present application provides a technical scheme: a kind of extrusion and traction structure for GPPS diffusion plate production, including extrusion component 1, extrusion component 1 includes extrusion equipment 101, and extrusion equipment 101 is used to process the raw material of GPPS diffusion plate into shape, the bottom of extrusion equipment 101 is fixedly connected with buffer component 3, the side of extrusion equipment 101 is provided with plate 5, buffer component 3 includes multiple support tubes 313, the inner wall of each support tube 313 is slidably connected with two limit blocks 311, every two limit blocks 311 are symmetrically arranged, the side of each limit block 311 is fixedly connected with buffer rod 310, the opposite side between every two adjacent limit blocks 311 is fixedly connected with buffer elastic block 312, and buffer elastic block 312 is used to absorb the force between two limit blocks 311, the end of each buffer rod 310 is fixedly connected with reinforcing block 308, the outer surface of each buffer rod 310 is provided with strong spring 309, and strong spring 309 is used to absorb the force generated by mechanical vibration, multiple reinforcing blocks 308 are evenly divided into two groups, one group of reinforcing blocks 308 is fixedly installed at the bottom of extrusion equipment 101, the outer surface between the other side reinforcing block 308 is fixedly connected with support plate 301, the top of support plate 301 is fixedly connected with fixed plate 302 close to both sides, two fixed plates 302 are provided with two rotating holes 303 on the outer surface, the inner wall of each rotating hole 303 is rotatably connected with rotating block 304, the opposite between every two rotating blocks 304 is fixedly connected with traction roller 305, and traction roller 305 is made of rubber material, for conveying plate 5, the outer surface of two traction rollers 305 respectively with the top and bottom of plate 5 contact, the outer surface of the side of support plate 301 is fixedly connected with supporting plate 307, the top of supporting plate 307 is provided with servo motor 306, the output shaft of servo motor 306 is fixedly connected with the side of one rotating block 304, the bottom of extrusion equipment 101 is fixedly connected with support component 4, support component 4 includes support frame 401, the top of support frame 401 is fixedly connected with mounting frame 402, multiple fixed rods 403 are fixedly connected between the opposite sides of mounting frame 402, multiple fixed rods 403 are rotatably connected with movable roller 404 outside, and movable roller 404 is used to movably support plate 5, and the material used is flexible hard rubber.

[0033] In this embodiment, when in use, the plate 5 extruded by the extrusion device 101 is very brittle, and the plate 5 is placed flat above the support assembly 4. By sleeving the plurality of movable rollers 404 outside the fixed rod 403, the inner wall of the movable roller 404 flexibly rotates with the fixed rod 403, and the outer material of the movable roller 404 is hard rubber, which can protect the surface of the plate 5 when in contact with the plate 5, so that the plate 5 will not be scratched.

During the traction process, the power supply instability and load changes that cause fluctuations in the traction speed are also compensated.

[0035] In use, the specific implementation manner of feeding is as follows: first, the main material is poured into the feeding bin 208 connected with the feeding pipe 206, and the auxiliary material is poured into the feeding bin 208 connected with the shunt pipe 204, the driving motor 212 is started to drive one of the runners 211 to rotate, since the two runners 211 are connected by the connecting chain 210, when one of the runners 211 rotates, the other runner 211 also rotates synchronously to drive the two closed discs 213 to rotate, the closed disc 213 is sleeved outside the feeding pipe 205 when rotating, the closed disc 213 drives 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 feeding pipe 205 and the feeding pipe 206 respectively, when rotating, the poured main material and auxiliary material enter the corresponding conveying bin 103 and extrusion bin 104 after passing through the feeding pipe 206 and shunt pipe 204, at this time, the heating belt 203 is powered to heat the raw materials passing through the shunt pipe 204 and feeding pipe 206, and the heated raw materials are more easily conveyed forward.

[0037] In use, in the embodiment, the main raw material used in the processing of the GPPS diffusion plate is general polystyrene, and the auxiliary materials are light diffusion agent and antioxidant. The light diffusion agent changes the propagation path of light in the plate 5. When light enters the GPPS diffusion plate containing the light diffusion agent, refraction, reflection and scattering occur on the surface of the light diffusion agent particles, so that the light becomes soft and uniform, and the glare is reduced. In addition, the GPPS may be oxidized by oxygen during processing and use, which may cause aging such as yellowing and brittleness. The antioxidant can inhibit this oxidation reaction. The main materials and auxiliary materials are poured into the two feeding bins 208 at the same time, and under the rotation of the two spiral feeding rods 215, the main materials and auxiliary materials are pushed forward, and the two auxiliary materials are conveyed into the two conveying bins 103 at the upper and lower positions respectively, and the main materials are conveyed into the extrusion bin 104 at the middle position. Under the continuous feeding action of the two spiral feeding rods 215, the main materials and auxiliary materials are mixed, and the meeting area is the meeting bin 102. The gap distance of the outlet of the meeting bin 102 is the thickness of the extrusion diffusion plate, so that the mixing of the main materials and auxiliary materials is completed during the extrusion process, and the production efficiency is improved.

[0038] The method for using the device and the working principle: in use, the main raw material used in the processing of the GPPS diffusion plate is general polystyrene, and the auxiliary materials are light diffuser and antioxidant. The role of the light diffuser is to change the propagation path of light in the plate 5. When the light enters the GPPS diffusion plate containing the light diffuser, refraction, reflection and scattering occur on the surface of the light diffuser particles, so that the light becomes soft and uniform, reducing glare. In addition, GPPS may be oxidized by oxygen during processing and use, causing aging such as yellowing and brittleness. The antioxidant can inhibit this oxidation reaction. By pouring the main material and auxiliary material into the two feeding bins 208 at the same time, the main material and auxiliary material are pushed forward under the rotation of the two screw feeders 215. The two auxiliary materials are transported into the two conveying bins 103 located above and below, respectively, and the main material is transported into the extrusion bin 104 located in the middle. Under the continuous feeding action of the two screw feeders 215, the main material and auxiliary material will be mixed. The intersection area is the intersection bin 102. The gap at the outlet of the intersection bin 102 is narrow, and the distance between the gaps is the thickness of the extruded diffusion plate. In use, the specific implementation of feeding is as follows: first, pour the main material into the feeding bin 208 connected to the feeding pipe 206, and pour the auxiliary material into the feeding bin 208 connected to the shunt pipe 204. By starting the drive motor 212, the output shaft is rotated to drive one of the two 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 also rotates synchronously to drive the two closed discs 213 to rotate. The closed disc 213 is sleeved outside the conveying pipe 205 and rotates to drive the reinforcing shaft 214 and the screw feeder 215 to rotate. The outer surfaces of the two screw feeders 215 are tightly attached to the inner walls of the conveying pipe 205 and the feeding pipe 206. When they rotate, the injected main material and auxiliary material enter the corresponding conveying bin 103 and extrusion bin 104 after passing through the feeding pipe 206 and shunt pipe 204. At this time, the raw materials passing through the shunt pipe 204 and the feeding pipe 206 are heated by electrifying the heating belt 203, making the heated raw materials easier to be transported forward. In use, the plate 5 extruded by the extrusion device 101 is very brittle and is placed flat on the upper surface of the support assembly 4. The movable rollers 404 are sleeved on the outside of the fixed rod 403, and the inner wall of the movable rollers 404 rotates flexibly with the fixed rod 403. The outer material of the movable rollers 404 is hard rubber, which contacts the surface of the plate 5 and protects the surface of the plate 5 from being scratched. The installation frame 402 and the support frame 401 support the extrusion device 101 and the plate 5. By making the plate 5 reach the upper surface of the traction roller 305 below, the servo motor 306 is started to rotate the output shaft, thereby driving the traction roller 305 below to rotate.When the plate 5 contacts the traction roller 305, the traction speed of the plate 5 is instantaneously increased. The GPPS diffusion plate is brittle, and the sudden tensile force can easily cause the plate to crack or break. However, because the support tube 313 and the two buffer rods 310 are composed of the strong spring 309 and the buffer elastic block 312 with micro elasticity, when the plate 5 is being pulled, the tensile force and impact force received by the plate 5 are absorbed by the elastic mechanism composed of the strong spring 309 and the buffer elastic block 312.

The model is selected according to the actual use, so the control mode and the wiring arrangement of the heating belt 203, the driving motor 212 and the servo motor 306 are not explained in detail.
