The invention discloses a paper guide device for a printer, and relates to the field of printing equipment. The device is provided with a paper guide mechanism, can quickly stack and precisely push corrugated boards on the paper guide mechanism into a conveying device for entering a next procedure, solves the problems of an easy blockage, deviation or even slippage of the corrugated boards in the conveying process and influence on the printing efficiency caused by slower conveying speed in traditional printer equipment, improves the working efficiency of the printer, further improves the product production efficiency, and increases the enterprise economic growth.

The invention discloses a multi-span greenhouse rainwater collecting and treating reusing device which comprises a water gathering pipe, initial rainwater filtering devices, a double power supply programming controller, a safety diverting well, a modular water storage pond, a pressurizing pump, a multi-medium filter, an ozone generator, a Venturi ejector and a clean water pond, wherein the initial rainwater filtering devices are used for initially realizing filtration of rainwater of 2-5mm; the double power supply programming controller is used for controlling the liquid level of the water storage pond and switching of the initial rainwater filtering devices; the safety diverting well is used for precisely filtering rainwater and controlling the water quantity; the ozone generator and the Venturi ejector are used for generating ozone water. The invention further discloses a rainwater collecting and treating reusing method based on the device. According to the device and method disclosed by the invention, the collected rainwater is disinfected and sterilized by using the ozone water so as to solve the problem that the water quality in the water storage pond is deteriorated, so that the rainwater is recycled, and therefore, the utilization efficiency of a water resource is improved, the regional ecological environment is improved, and an extra economical benefit is further generated.

The invention discloses a method for detecting diseases of crop leaves. The method comprises the following steps: acquiring a leaf image of a crop to be detected, uploading the leaf image to an on-line detection platform with a disease image automatic identification function and a professional diagnosis system function, performing scab image partitioning and identification on the leaf of the crop to be detected, outputting a detection result, and giving a control suggestion, wherein the scab image partitioning is as followings: converting an original image from a red, green and blue (RGB) model space to a horizontal situation index (HSI) space, respectively extracting an H component image and an I component image in the HIS space, and performing dynamic threshold value partitioning on the H component image by using a maximum between-cluster variance method to preliminarily obtain a scab region image; superimposing the I component image on the partitioning result of the H component image to eliminate misjudgment caused by a background region on the scab partitioning, thus obtaining a binary image only comprising the scab region; and performing subsequent treatment on the partitioning result by using a morphological method, and finally obtaining a complete scab image of the leaf of the crop to be detected.

The invention discloses a power supply box glue dispensing device capable of dispensing glue in multiple groups simultaneously. The power supply box glue dispensing device comprises an operation platform, wherein a cross chute is formed in the top of the operation platform; the top of the operation platform is divided into four areas by the cross chute; glue dispensing platforms are arranged in all four areas; a connecting block is connected inside the cross chute through a driving device; a holding box is connected with the top of the connecting block; a rotating disc and a bottom plate are arranged from left to right in sequence at the bottom of the inner cavity of the holding box; the bottom plate is divided into four arc-shaped surface plates by four long-stripy grooves formed in the top of the bottom plate; the arc-shaped surfaces of the arc-shaped surface plates are matched with the rotating disc; opening grooves are formed in two sides of each of the four arc-shaped surface plates; a push rod is connected with one side which is cut in an arc manner, of the rotating disc; the other ends of the push rods extend into the opening grooves. Due to cooperation of the driving device, the connecting block, a motor and ratchet wheel structures, the effect that a plurality of power supply boxes are dispensed with glue simultaneously through one glue dispensing device can be achieved, the working efficiency and the production efficiency are improved, and the economic growth can be promoted.

The invention relates to a composite sphere-form molten steel purifying agent and a production method thereof and belongs to the technical field of steelmaking. The molten steel purifying agent is a composite sphere in form, the composite sphere is composed of a pellet core and a shell, the pellet core is made of a metal material, the shell is made of carbonate, the pellet core is mainly composed of a mixture of alloy powder of silicon, manganese and aluminium, and the shell is mainly composed of one or mixture of not more than three of calcium carbonate, magnesium carbonate, sodium carbonate, calcium oxide and magnesium oxide. The molten steel purifying agent has the advantages that a formula is scientific, a technology is simple, inclusions in molten steel can be effectively removed, total oxygen content in steel is reduced, steel product quality is improved, and smelting cost is reduced; and the molten steel purifying agent also can be used for purifying and refining molten nonferrous metal in a liquid state.
