Description
Technical Field
[0001] The utility model relates to the technical field of extruders, in particular to an extrusion device for preheating and uniform plasticization. Background Art
[0002] The main production process of plastic woven bags is to use plastic raw materials through mixing, film extrusion, cutting, unidirectional stretching to flat wire, and finally weaving through warp and weft; the screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material, and then form it through the die.
[0003] In the existing technology, during the preheating process of plastic raw materials, the raw materials located in the central area are far away from the heat source and have poor fluidity, which makes them prone to uneven heating. As a result, the raw materials in the peripheral area are unable to be completely melted for a long time, while the peripheral raw materials are continuously exposed to the high-temperature heat source and there is a risk of overheating, which affects production efficiency and product quality.

The auxiliary blanking module includes a fixed ring frame and a movable ring frame. A plurality of slots are equidistantly arranged on the fixed ring frame. A sliding seat is fixedly connected in the plurality of slots. An impact head is slidably connected in the plurality of sliding seats. The movable ring frame is movably connected to the outside of the blanking barrel. A gear ring is fixedly connected to the outside of the movable ring frame. The processing module also includes a rotating rod, which is rotatably connected to the mounting rod frame, and the output end of the universal motor is fixedly connected to the upper end of the rotating rod. The lower end of the rotating rod is fixedly connected to a driving gear, and the upper ends of multiple rotating shafts are fixedly connected to driven gears. Multiple driven gears are meshed with the driving gear, and a protective plate is fixedly connected to the inner wall of the preheating barrel.
[0006] By providing a processing module, after the plastic raw material falls into the preheating cylinder, the protective plate can prevent the raw material from falling into the gap between the driving gear and the driven gear to prevent jamming and clogging. The heater is started to preheat the plastic raw material in the preheating cylinder, and the melted raw material falls into the main shell through the interlayer filter plate. At the same time, the universal motor is started to rotate the rotating rod, and the mutual engagement of the driving gear and the driven gear synchronously drives multiple shafts and flip plates to rotate. The flip plate continuously flips the raw material located at the center of the preheating cylinder to the surrounding areas, thereby increasing the fluidity of the raw material, enabling all raw materials to evenly contact the heat source, improving the uniformity of heating, and avoiding uneven heating that causes part of the raw material located at the center to be unable to melt for a long time due to insufficient heating, thereby improving production efficiency and product quality.
[0007] In a preferred solution, the auxiliary blanking module also includes a servo motor, which is fixedly connected to one side of the blanking barrel, and the output end of the servo motor is fixedly connected to a toothless gear, the teeth of the toothless gear can mesh with the gear ring, and the ends of the multiple impact heads away from the blanking barrel are fixedly connected to a pulling rope, and the ends of the multiple pulling ropes away from the impact heads are fixedly connected to the movable ring frame, and the ends of the multiple impact heads away from the blanking barrel are fixedly connected to a spring, and the ends of the multiple springs away from the impact heads are fixedly connected to an inner wall of one side of the sliding seat, a mounting hole is opened on the main shell, a screw rod is rotatably connected in the mounting hole, and a drive motor is fixedly connected to one side of the main shell, and the output end of the drive motor is fixedly connected to one end of the screw rod.
[0008] By setting up an auxiliary unloading module, since the plastic raw material particles are uneven in shape and have poor fluidity, they are easy to accumulate and form bridges, which leads to blockage and feeding interruption. The servo motor is started to rotate the toothless gear. When the toothless gear is engaged with the gear ring, the gear ring drives the movable ring frame to rotate, and the impact head is pulled by the pulling rope to make the impact head compression spring slide away from the unloading barrel. When the toothless gear is disengaged from the gear ring, the spring elastically recovers, pushing the impact head to reset quickly, impacting the unloading barrel, and performing reciprocating operation to make the unloading barrel vibrate continuously, thereby ensuring smooth unloading and avoiding blockage of plastic raw materials.
[0009] From the above, it can be seen that the pre-heating and uniformly plasticizing extrusion device provided by the utility model can increase the fluidity of the raw materials through the processing module and utilize the rotational movement of the flip plate, while dispersing the raw materials in the central area of the preheating cylinder to the surrounding area, eliminating the problem of local uneven heating, and avoiding the uneven heating that causes part of the raw materials located in the center position to be unable to melt for a long time due to insufficient heating, thereby improving the overall heating uniformity of the raw materials and improving production efficiency and product quality.
