The invention relates to a method and a device for automatically detecting powder material accumulation density, relating to a device for detecting powder (granular) material accumulation density. The method comprises the following steps of: (1) connecting a material dividing hopper with an original spiral conveyer pipe; (2) opening a material dividing valve at the lower part of the material dividing hopper so that materials fall to a material weighing hopper supported by a weighing sensor; (3) scraping stacks at the top of the material weighing hopper through a material pushing scraping plate driven by a material pushing cylinder; (4) transmitting weight information of the material weighing hopper to a PLC (programmable logic controller) control system for calculating, comparing and displaying by the weighing sensor; (5) opening a material discharging valve at the lower part of the material weighing hopper so that the materials fall to a material receiving hopper and enter to a secondary spiral conveyer; and (6) pushing the materials falling from the material receiving hopper to be combined with the materials falling from an original spiral conveyer material discharging tube and sending to next procedure together by the secondary spiral conveyer. The device disclosed by the invention has the advantages of automatic identifying function, high accuracy, fast speed and high efficiency; and the device is capable of realizing full check, and effectively controlling the product quality.

The invention relates to a conveyor pipeline for a formed plastic environment-friendly recovering and granulating machine set, which is characterized in that the conveyor pipeline comprises a radial material loading pipeline consists of a material loading blower and a pipeline, a tangential feeder which is connected with the radial material loading pipeline and a regular polygon feeding tank which is connected with the tangential feeder, wherein the inside of the feeding tank is provided with a stirrer; a main body of the tangential feeder is cylindrical, the top of the main body is provided with a tangential air inlet pipe, and the middle of the main body is provided with a middle separating air pipe which is vertical to the tangential air inlet pipe; and the feeding tank is a regular polygon cube, and the top of the regular polygon cube is provided with an upper cover, wherein the main body of the regular polygon cube is divided into an upper part, a middle part and a lower part, the upper part is a sealing structure, the middle part is a detachable net structure, the lower part is a tapered sealing structure, and the three parts are connected through a frame body. The conveyor pipeline adopts a closed circular material supply system, improves the environment-friendly regeneration utilization rate, reduces the recovery cost, saves the energy loss, and reduces the recovery secondary pollution.

The invention relates to a pneumatic drill. The pneumatic drill comprises an air filter and an air pump. The pneumatic drill is characterized in that the pneumatic drill further comprises a negative-pressure pneumatic drill and a chip separator, wherein the negative-pressure pneumatic drill, the chip separator, the air filter, and the air pump are sequentially connected into a whole through air pipes; the negative-pressure pneumatic drill comprises a drill bit, a rotor blade holder, guide impellers, rotor impellers, a sleeve, a gas distribution disc, a casing pipe, an elastic retainer ring and an air pipe connector, wherein the chip separator comprises a lower housing, an upper housing, a chip accommodating bottle and separating impellers. The pneumatic drill provided by the invention not only achieves the function of the pneumatic drill, but also achieves the function of automatic online punching of deformable and soft hollow thin-walled materials; positions of the punching points are accurate and the incision of punching holes is round and uniform; chips and powders produced during the working process are less, so that the pneumatic drill has the advantage of high efficiency and environmental protection. The hollow drill bit is adopted and each group of cutting edges has the same shapes; the chips are discharged from the interior. Therefore, regardless of the positive direction or the reverse direction, a reversing valve is not required; the structure is simpler and more reliable.
