Description

Technical Field

[0001] The utility model relates to the technical field of extrusion equipment, in particular to a high-efficiency extrusion molding device for a multi-layer diffusion plate. Background Art

[0002] The biggest feature of the diffuser is that it causes great interference to light. No matter how many degrees the original design of the light distribution curve is, as long as the light passes through the diffuser, it will change the beam angle to 160-176°. Therefore, when viewed from the side, the panel of the lamp has a layer of fog. This proves that the beam angle is as large as 160-176°. The best proof is that the larger the beam angle, the lower the illumination. Some will also produce filtering, so that some wavelengths cannot penetrate, causing color deviation. If the surface is treated with light interference again (for example: frosting, embossing), the transmittance will be even lower due to the natural phenomenon of geometric optics. Therefore, the base material used to make the diffuser should have the lower the refractive index, the better, and the interference with light will be lower. The diffuser is extruded by an extruder during production, and the multi-layer diffuser is equipped with a multi-layer co-extrusion composite head at the extrusion end of the extruder, which can extrude multiple layers of material at the same time to form a diffuser with a complex structure. The current extrusion molding device for multi-layer diffuser plates generally places polycarbonate, polystyrene, acrylic and other auxiliary materials in granular form into the inside of a hopper, and transports the granular materials to the inside of an extruder through the hopper. The extruder heats and melts the materials and transports them to the extrusion head for extrusion molding. However, the granular raw materials may cause blockage inside the hopper, thereby affecting the extrusion efficiency of the diffuser plate. At the same time, the heating equipment of the extruder is set on the surface of the extruder, which may easily cause the outer side of the raw material to melt easily when the large particles of raw materials melt, while the middle part is not easy to melt. This will cause the finished product to be mixed with unmelted fine particles, resulting in uneven overall strength distribution of the processed finished product and reduced quality of the finished product.

Through the operation of the motor 12, the rotating rod 14 can drive the other rotating rod 14 to rotate through the two gears 11, so that the crushing rollers 9 on the surface of the rotating rod 14 can crush the larger granular raw materials to facilitate subsequent heating and melting. When rotating, the rotating rod 14 can also drive the extrusion plate 10 to move, and the extrusion plate 10 can be moved to the surface of the connecting plate 8 to squeeze it and move it, so that the connecting plate 8 can drive the rotating rod 6 and the material-moving rod 7 to move back and forth, so that the material-moving rod 7 can move the raw materials inside the funnel 13, thereby preventing the granular raw materials from clogging the funnel 13 and affecting the extrusion efficiency of the diffusion plate.

[0027] Furthermore, the extrusion plate 10 contacts the surface of the connecting plate 8, which is convenient for the extrusion plate 10 to move to the surface of the connecting plate 8 and continue to move, so as to squeeze the connecting plate 8, so that the connecting plate 8 drives the rotating rod 6 and the material-moving rod 7 to rotate.

[0028] Furthermore, the extrusion plates 10 on the surfaces of the two rotating rods 14 are arranged in opposite directions, so that after the extrusion plate 10 on one of the rotating rods 14 squeezes the connecting plate 8 in the direction of the other rotating rod 14, the extrusion plate 10 on the other rotating rod 14 can be moved to the surface of the connecting plate 8 to squeeze it and reset it, so that the rotating rod 6 connected to the connecting plate 8 can drive the material moving rod 7 to move back and forth, so as to facilitate the material moving of the raw materials inside the funnel 13 through the material moving rod 7.

[0029] Furthermore, a motor 12 for driving the rotating rod 14 is installed on the surface of the trough 4 , and the motor 12 is connected to any one of the two rotating rods 14 .

[0030] Furthermore, the two rotating rods 14 pass through the trough 4 and are respectively connected to the gears 11, and the two gears 11 are meshingly connected, so that when one of the rotating rods 14 rotates, the other rotating rod 14 can be driven to rotate by the two meshingly connected gears 11.
