The invention discloses a controlled-release fertilizer coating system and a control method thereof. The system comprises a urea metering and conveying system, a powder metering and conveying system, a liquid metering and conveying system, a plurality of disc coating machines, receiving belt conveyors, finished product packaging devices and a control computer, wherein the receiving belt conveyors are arranged below discharge hole of the disc coating machines; each finished product packaging device is arranged below one end of each receiving belt conveyor; and the urea metering and conveying system, the powder metering and conveying system, the liquid metering and conveying system, the plurality of disc coating machines, the receiving belt conveyors and the finished product packaging devices are all connected with the control computer. According to the controlled-release fertilizer coating system, the coating process which is compact in structure and complete in operation can be automatically finished through the control computer; the control accuracy is relatively high; the plurality of disc coating machines can be quantitatively fed, thus energy sources and manpower resources are greatly saved; the production efficiency is effectively improved; the production cost is reduced; and the controlled-release fertilizer coating system can be widely applied to the field of coating production.

The invention discloses a switch control device. The switch control device comprises a shell, wherein a positioning device is arranged on the shell; a pushing structure used for pushing a switch to be switched on and off is arranged on one side of the shell; the pushing structure comprises two sliding slots which are formed in the shell; openings are formed in one side of each of the two sliding slots; flanges are arranged at the opening ends of the sliding slots; springs propped against the flanges are arranged at the interiors of the sliding slots; a sliding block is arranged at the other end of each spring in a propping manner; ejection rods are arranged on the sliding blocks in the direction facing towards the openings of the sliding slots; magnets are arranged on the sliding blocks; electromagnets are arranged at the closed ends of the sliding slots and are sequentially connected with a delayer, a power supply and a shifting switch; when the electromagnets are electrified, the electromagnets and the magnets mutually repel; the shifting switch is arranged on the other side of the shell; the shell is mounted on the switch; the shifting switch is switched off by the switch after the switch is pushed by the pushing structure. Through the adoption of the device, the problem that a person goes to bed in the dark after switching off the switch under the condition that the position of the switch is far from the bed can be solved.

The invention relates to the technical field of injection molding equipment, in particular to an injection molding manipulator and an injection molding method. The injection molding manipulator comprises a manipulator, a material bearing frame, a shifting mechanism, a material inspection worktable, a defective product device box, a shifting support frame, a shifting plate, a detection sensor, an error-proof detection shaft, a shifting cylinder, a part taking and placing device, a material taking device, an auxiliary parting device and a control device. The control device controls the shiftingmechanism to move a part to a position where the manipulator can grasp the part; then the part is moved toward a mold by the manipulator, and the material taking device takes out an injection molded finished product from the mold; then the part is implanted into the mold through the part taking and placing device; after that, defective products judged by an injection molding machine are put into the defective product box through the manipulator; and the injection molded finished product is placed on the worktable to be further inspected along a feeding belt by the material taking device. In this way, a complete set of smooth and quick operations of a product with parts placed in a mold for injection molding together can be achieved, so that the working efficiency is effectively improved.

A manual operation unit and a manual operation group of a medical device (D), which can be used on an endoscope (E); wherein the operation unit (2) has a supporting body (7; 121; 121'; 121b'), which is configured to adhere, in use, to an area of the user's hand, in particular a finger; and a retaining portion (8; 122a; 122a'; 122b'), which is connected to said supporting body (7; 121; 121'; 121b')and configured to be hooked, in use, to the medical device (D).

The invention relates to a method for processing a material piling and taking machine track by using tools and belongs to the technical field of machining. The method for processing the material piling and taking machine track comprises the following technical steps of: (1) performing rough machining on a track blank, namely eliminating deformation caused when a material is heated in a blanking process; (2) performing split processing, namely machining and welding alternatively and welding the track with a corresponding frame by using a welding tool I when frames are not assembled together; (3) performing finish machining on the track, namely performing finish machining on the track until the track meet the requirements of size, roughness and form and position tolerance; and (4) performing assembly and welding, namely using a welding tool II and a welding tool III to ensure relative position accuracy and welding four independent frames on which the track is positioned. The method has the advantages of simple process, time saving and labor saving properties, low manufacturing cost, reliable positioning, simple, convenient and rapid operation, easy grasping for users, high processing efficiency, high processing accuracy, high product quality and the like.

The invention discloses a method for producing low-molecular chondroitin sulfate by a catalytic process, which comprises the following steps: (1) boiling with water; (2) steaming; (3) enzymolysis; (4) alcohol precipitation; (5) catalysis; (6) ultrafiltration; (7) alcohol precipitation; and (8) dehydration and drying. By using the catalyst Cu / ZSM-5 molecular sieve to degrade the chondroitin sulfate, the method has the advantages of mild and controllable conditions, fewer residual metal ion impurities in the degraded solution and no need of ion exchange resin removal, is simple to operate in the production process, and is suitable for large-scale production; and the product quality is stable, and the chondroitin sulfate recovery rate is up to higher than 80%.
