Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1, as a non-limiting embodiment, the present invention provides a filament film recycling granulation extruder comprising: a drive motor 1, a power transmission system 2, a reduction distribution gearbox system 3, a hopper 4, a barrel 5, a screw system 6, a spline housing 7, a heater 8, a barrel support 9, and a carriage 10.

As can be seen from fig. 1, the driving motor 1 transmits power from the power transmission system 2 to the deceleration distribution gearbox system 3, the power is decelerated and converted by the deceleration distribution gearbox system 3 into two same-direction rotating directions and then distributed to the two conical screws of the screw system 6, so that the two conical screws 7 obtain same-direction rotation or opposite-direction inward rotation, the screw system 6 and the deceleration distribution gearbox system 3 are connected by a spline housing 7, a heater 8 is installed on the machine barrel 5, the discharge end of the machine barrel 5 is supported by a machine barrel supporting device 9, all components are installed on a rack 10, and materials are fed into the machine barrel 5 through the hopper 4, are dragged into the machine barrel 5 through thorns at the screw feeding section in the material port, and enter the machine barrel 5.

As shown in fig. 2 and 3, the screw system 6 comprises two conical screws 60, the rotation directions of the two conical screws 60 are the same, each conical screw 60 comprises an extrusion section 601, a gas discharge section 602, a compression section 603, a pre-compression section 604 and a feeding section 605, wherein the feeding section 605 is provided with thorns 606. The direction of the threads of the two conical screws 60 may be the same as shown in fig. 2, or may be opposite to the direction of the threads shown in fig. 3 but rotating inward, so that the thorns 606 are spirally distributed at the threads of the feeding section 605. As shown in fig. 4, as the conical screw 60 rotates, material is momentarily drawn into the barrel by the spur 606 on the screw.

Because the film material and the waste silk material have the characteristics of fluffiness and difficult feeding, the design of the conical double screws is adopted, the diameter of the large end of each conical screw is set to be 1.5-2.5 times of the diameter of the small end, the effective length of the thread part of each conical screw is set to be 30-50 times of the diameter of the small end, and the conical double screws have the advantages of large diameter of the screw at the feed opening, large opening of the feed opening, larger material consumption compared with a single screw, forced conveying effect of the double screws, and higher feeding efficiency compared with the single screw.

As a further non-limiting embodiment, as shown in fig. 5, when the thread directions of the two conical screws 60 are the same direction, the reduction distribution gear box 3 includes an input gear a, a secondary gear B, a first output gear 31, a second output gear 32, an idler gear C, a universal joint 30, a thrust bearing D, a first output shaft 33, and a second output shaft 34. For the defect that the extrusion torque gear wheel is easy to damage, the distribution box and the gear box are connected by adopting the universal joint 30 design, the distribution shaft and the reduction gear shaft are arranged in a non-coaxial mode, the center distance between the first output gear 31 and the second output gear 32 is enlarged, meanwhile, the two gears are changed into common cylindrical gears from conical gears, the manufacturing difficulty is reduced, the manufacturing precision is improved, and meanwhile, the gear torque is improved.
