6results about How to "Improve reflow effect" patented technology

The invention discloses a polymerization inhibitor for printing ink, the printing ink and application of the printing ink. Relates to the field of ink polymerization inhibitors. The component of the polymerization inhibitor for the printing ink comprises p-hydroxyanisole, and the printing ink is selected from azo dye type printing ink or mixed printing ink of anthraquinone dye and azo dye. According to the polymerization inhibitor disclosed by the invention, p-hydroxyanisole is added into azo dye type ink or anthraquinone-azo mixed type ink as an active component, so that the reflux performance of an electrowetting display device after light aging can be remarkably improved.

This utility model belongs to the technical field of mixing equipment, specifically relating to an electroplating solution mixing and stirring device. It includes a base, a tilting frame rotatably connected to the top of the base, a mixing tank detachably mounted on the outer top of the tilting frame, a top cover detachably mounted on the top of the mixing tank, a liquid outlet pipe located at the bottom axis of the mixing tank, and feeding mechanisms on the upper and lower sides of the mixing tank. The feeding mechanism includes an upper feeding pipe and a lower feeding pipe. The upper feeding pipe is located at the top edge of the top cover, and the lower feeding pipe is located on the side of the liquid outlet pipe. An internal flow pipe is fixedly connected to the axis of the liquid outlet pipe. The beneficial effect of this utility model is that, by providing feeding mechanisms, materials can be added from both the top and bottom of the mixing tank, improving the reflux effect at the bottom of the mixing tank, thereby making the different raw materials mix more evenly and thus improving the electroplating quality of the electroplating solution.

This utility model relates to a magnetic levitation connection transmission line, including a frame and a magnetic levitation conveyor mechanism, a belt conveyor mechanism, and a carrier mounted on the frame. The belt conveyor mechanism can connect with the magnetic levitation conveyor mechanism, the carrier is transported and moved by the magnetic levitation conveyor mechanism, and the carrier can return to the magnetic levitation conveyor mechanism via the belt conveyor mechanism. The belt conveyor mechanism includes a belt arranged along the conveying direction of the magnetic levitation conveyor mechanism. The key feature is that a magnetic suction element is provided inside the belt, and a magnetic element is provided at the bottom of the carrier that can cooperate with the magnetic suction element's attraction. The advantages are: by setting a magnetic suction element inside the belt and a magnetic element at the bottom of the carrier, the attraction between the magnetic suction element and the magnetic element generates a large frictional force, making the carrier more stable and reliable when it is driven back by the belt. This transmission line has a simple structure, low cost, and better return effect, and does not cause wear on the belt.

This utility model discloses a doctor blade system and a cardboard printing machine. The doctor blade system includes: a mounting frame and a doctor blade mounted on the mounting frame; multiple nozzles spaced apart on the side of the mounting frame away from the doctor blade, each nozzle having a fan-shaped outlet and capable of spraying cleaning fluid towards the doctor blade; the mounting frame has a return channel with a bottom wall, including a first end and a second end opposite to each other. The first end extends to the doctor blade, and the bottom wall gradually slopes downwards from the first end to the second end. The nozzles spray cleaning fluid towards the doctor blade, thereby automatically cleaning the doctor blade. The inclined bottom wall of the return channel improves ink return efficiency.

The utility model relates to the technical field of electroplating bath cleaning, in particular to a backflow device for electroplating bath cleaning, which is provided with a negative pressure backflow mechanism driven in a screwed manner, is matched with stirring to avoid sediment accumulation, has a better backflow effect and improves the practicability. Comprising a backflow cylinder, an input pipe, an output pipe, a connecting plate, an absorption head, a stirring motor, a stirring rod, stirring blades, a piston, a threaded pipe, a supporting frame, a reciprocating driving motor and a threaded rod, the inner side of the backflow cylinder is vertically and slidably connected with the outer side of the piston, the middle of the top end of the piston is connected with the bottom end of the threaded pipe, and the outer side of the upper portion of the backflow cylinder is connected with the lower side in the supporting frame; a connecting plate is further connected to the input pipe, one side of the top end of the connecting plate is connected with the bottom end of a stirring motor, the output end of the stirring motor is connected with the top end of a stirring rod, multiple sets of stirring blades are connected to the outer side of the stirring rod, and the output end of the backflow cylinder communicates with a set of filtering mechanisms through an output pipe.

This utility model relates to a two-stage cooling structure for the motor rotor of a compressor, comprising a front housing and a rear housing mounted together from left to right. A cooling inlet is connected to the right side of the motor cooling cavity located inside the motor housing. A high-pressure hot gas outlet is connected to the right side of the main compression flow channel. The high-pressure hot gas outlet is connected to a cooler via a high-pressure hot gas connecting pipe, and the cooling inlet is connected to the cooler via a cooling inlet connecting pipe. Several guide vanes are evenly distributed along the circumference on the right side of the impeller, and a drain outlet connected to the motor cooling cavity is provided on the left side of the motor housing. This utility model utilizes the high-pressure hot gas compressed by the compressor, which, after cooling, effectively cools the surface of the motor stator and rotor assembly, forming a closed gas circulation path inside the compressor, avoiding high-temperature accumulation and improving equipment operational reliability.
