人工将塑料粒倒进料斗12中，塑料粒通过料斗12进入到螺杆腔中，螺杆腔通过加热装置的加热使其里面的塑料粒塑化，并在挤出电机和挤出减速箱11的驱动下使挤出螺杆15将塑化的塑料沿螺杆腔向挤出模具14挤出，塑化的塑料经挤出模具14成型挤出，在挤出模具14成型挤出处通过冷却风机18将要挤出的塑料制品进行降温；经挤出机1挤出的塑料制品经过冷却装置2冷却；经冷却后进入皮带牵引机3中，上传送皮带31和下传送皮带32将成型塑料输送至切粒机4上，切粒机4上的传动电机41通过传动皮带43带动送料滚轮46将塑料制品输送至切粒装置，切粒电机42通过切粒传动皮带49带动切粒滚刀47转动，完成一次切料动作，送料压轮45将后续的塑料制品端压住，送料滚轮46继续送料，完成后续的切粒工作。 Manually pour the plastic pellets into the hopper 12, the plastic pellets enter the screw cavity through the hopper 12, the screw cavity is heated by the heating device to plasticize the plastic pellets inside, and the extrusion motor and the extrusion gearbox 11 Driven to make the extrusion screw 15 extrude the plasticized plastics along the screw cavity to the extrusion die 14, the plasticized plastics are shaped and extruded through the extrusion die 14, and the cooling fan 18 will The extruded plastic product is cooled; the plastic product extruded by the extruder 1 is cooled by the cooling device 2; after cooling, it enters the belt tractor 3, and the upper conveyor belt 31 and the lower conveyor belt 32 convey the molded plastic to the pelletizing machine. On the machine 4, the transmission motor 41 on the granulator 4 drives the feed roller 46 through the transmission belt 43 to transport the plastic products to the granulation device, and the granulation motor 42 drives the granulation hob 47 to rotate through the granulation transmission belt 49 to complete one cycle. Material cutting action, feeding pinch wheel 45 pushes down the end of follow-up plastic product, feeding roller 46 continues feeding, completes follow-up pelletizing work.
以上的实施例只是在于说明而不是限制本实用新型，故凡依本实用新型专利申请范围所述的方法所做的等效变化或修饰，均包括于本实用新型专利申请范围内。 The above embodiments are only intended to illustrate rather than limit the utility model, so all equivalent changes or modifications made according to the method described in the scope of the patent application of the utility model are included in the scope of the patent application of the utility model.
