The utility model relates to a disc edge scraping device for a pellet pelletizing disc, and belongs to the technical field of pellet production in the metallurgical industry. According to the technical scheme, according to the material scraping sequence, an inclined material scraping plate (10) and a straight material scraping plate (11) are sequentially arranged on the edge of a pelletizing disc (3), a certain included angle is formed between the inclined material scraping plate (10) and the pelletizing disc (3), the straight material scraping plate (11) is perpendicular to the pelletizing disc (3), the inclined material scraping plate (10) is connected to the lower end of an inclined material scraping plate pull rod (9) through a rib plate, and the inclined material scraping plate pull rod (9) is connected with the straight material scraping plate (11). The upper end of the inclined scraping plate pull rod (9) is rotationally connected to the suspension frame (5) through a rotating shaft (7), the straight scraping plate (11) is connected to the lower end of the straight scraping plate pull rod (8) through a rib plate, and the upper end of the straight scraping plate pull rod (8) is connected to the suspension frame (5). The device has the advantages that accumulated materials on the edge of the pelletizing disc can be cleaned in real time, and materials and green pellets moving upwards along with the pelletizing disc are effectively blocked.

The utility model discloses a thread feeding mechanism for textile processing, relates to the technical field of textile equipment, and aims to provide a thread feeding mechanism for textile processing, which can automatically penetrate threads into the equipment, and has the technical key points that the thread feeding mechanism comprises a base, a shell is arranged on the base, and a driving wheel and a driven wheel are rotationally arranged on the side surface of the shell; a belt pulley set is arranged between the driving wheel and the driven wheel, a driving motor is arranged on the end face of the driving wheel, and an overturning component is arranged on the axis of the driven wheel in a sleeved mode. The threading device has the technical effects that by arranging the overturning part and the threading part, the overturning part drives the tensioning wheel to rotate downwards, so that the tensioning wheel moves to the position between the driving wheel and the driven wheel and extrudes a silk thread lapped on the tensioning wheel downwards, the silk thread is attached to the lower portion of the tensioning wheel, on one hand, the silk thread is tightened, on the other hand, the path of the silk thread is changed, and the threading effect is improved. Therefore, enough wrap angles are formed between the silk threads and the driving wheel and the driven wheel, and the purpose of automatic threading is achieved.

The constant-temperature drying box comprises a machine box shell and a drying inner box in the machine box shell, a transverse grid and a vertical grid which are located in the machine box shell are movably installed on the two sides of the drying inner box respectively, a vertical connecting rod is movably connected to the middle of one side of the transverse grid, and a horizontal connecting rod is movably connected to the middle of the other side of the vertical connecting rod. A transverse connecting rod is movably connected to the middle of one side of the vertical grid, and an up-down swing telescopic motor and a front-back swing telescopic motor are installed at the positions, corresponding to the vertical connecting rod and the transverse connecting rod, in the case shell correspondingly. The vertical air swinging telescopic motor drives the transverse grid to swing up and down, the front-back air swinging telescopic motor drives the vertical grid to swing front and back, and therefore the effect of changing the hot air flowing direction and path is achieved, the transverse grid and the vertical grid swing periodically, all parts in the drying inner box can make contact with flowing hot air, and the drying effect is improved. Hot air circulation dead angles are avoided, and the heating uniformity of experimental samples is improved.

The utility model discloses a natural convection drying box without a fan, which comprises a box body, a wind collecting cover, a heater and a storage rack, the storage rack is arranged in the box body, the wind collecting cover can be transversely arranged in the box body and is positioned above the storage rack, an exhaust pipe joint is arranged at the top of the box body, a flexible air pipe is arranged between the exhaust pipe joint and the wind collecting cover, and the flexible air pipe is connected with the heater. A first partition plate and a second partition plate located above the first partition plate are arranged at the bottom of the box body, an air inlet chamber is defined by the bottom face of the first partition plate and the inner wall, below the first partition plate, of the box body, a heating chamber is formed between the first partition plate and the second partition plate, and the heater is arranged in the heating chamber. Through reciprocating transverse movement of the air collecting cover, the path of air flow can be changed, S-shaped ascending air flow is formed, the air collecting cover can make contact with more materials, the uniformity of heating and drying of the materials is improved, and the drying time is shortened.
