The invention relates to a buying behavior-based recommendation method and device. The method comprises the following steps of: counting the first effective order quantity generated by advertising within unit time; counting the second effective order quantity generated by malls within the unit time; and comparing the first effective order quantity with the second effective order quantity to obtain a buying interest sequence table of a user, wherein if the first effective order quantity is greater than the second effective order quantity, the advertising channel is superior to the malls in the buying interest sequence table of the user; if the first effective order quantity is less than the second effective order quantity, the malls are superior to the advertising channel in the buying interest sequence table of the user. The invention has the following beneficial effects: an interesting promotion way is delivered to the user according to the behavior situation of the user, then an advertising platform can select a more reasonable promotion way based on the buying behaviors of the user, and various promotion resources are utilized more reasonably.

The invention discloses an energy-saving efficient plastic granulator, a feeding screw rod is rotationally arranged in a feed barrel, a scraper plate is rotationally arranged in a granulation extrusion cavity, a scraping block is arranged on the excircle of the scraper plate, the scraping block is closely attached to the inner cylinder wall of an extrusion die cylinder, the cylinder wall of the extrusion die cylinder is provided with extrusion holes, and a rotational cut-off tool is arranged on the outer cylinder wall of the extrusion die cylinder; the energy-saving efficient plastic granulator is characterized in that: the inner cylinder wall of the feed barrel is provided with a plurality of vertical ribs, the vertical ribs pass through, from up to down, the whole feed cylinder height, the top circle of the vertical ribs is matched with the excircle of the feeding screw rod, adjacent vertical ribs, and the inner cylinder wall of the feed barrel and the excircle of the feeding screw rod enclose a space to form an inner air circulation channel of the feed barrel. The energy-saving efficient plastic granulator uses the scraping block to grind a material to produce heat to melt the material for plastic granulation, the energy-saving efficient plastic granulator can always smoothly exhaust in the working process, and the unique scraper plate is designed to avoid local overheating of the material so as to avoid obstruction of heat transfer, so that automatic control of blanking and feeding can be achieved, and the entire normal high-speed granulation process and high granulation quality can be ensured.

The invention discloses a workpiece reversing device and workpiece placing equipment provided with the same. The workpiece reversing device comprises a transmission unit for conveying a workpiece andan outputting mechanism, wherein the outputting mechanism is arranged on the transmission unit and comprises a plurality of outputting channels and reversing units arranged on the paths of the outputting channels; and the reversing units adjust the workpiece outputting direction. The outputting mechanisms are arranged on the transmission unit; when the workpieces are conveyed on the outputting channels, the reversing units adjust the direction during the conveying process, and conveying of the workpieces in the outputting channels is not delayed at the same time, so that the defect that the surface of the workpiece is worn when an external clamping device clamps the workpiece is overcome, and the situation that the workpiece quality is reduced due to clamping is avoided; and the reversingunits are arranged on the conveying paths of the outputting channels to avoid manual direction adjustment of the workpiece and increase the productivity of the workpiece.
