The invention discloses a phonetic braille conversion machine and a conversion method thereof, comprising a conference table, wherein a No. 1 cavity is arranged in the No. 1 cavity, and a No. 1 cavity which penetrates upwards through the conference table is arranged on the upper side of the No. 1 cavity. A through slot, a No. 1 spring slot is provided in the top wall of the No. 1 cavity, and a Braille printer is arranged in the No. 1 cavity. The Braille printer is located on the right side of the No. 1 through slot and the No. 1 The spring slot is located on the left side of the No. 1 through slot. The invention can automatically convert the voice information in the meeting into Braille, and after the user obtains the information, the invention can make the paper carrying the Braille be broken and regenerated. After processing, it can be reused in real time; when the meeting materials need to be recorded, the invention can cut the paper carrying the information and discharge it; the invention can automatically replenish the original pulp, avoiding the regenerated paper from breaking or becoming thinner, affecting The effect of braille printing.

The invention belongs to the technical field of cloth processing, and specifically relates to a digital inkjet cloth printing machine, which includes a support seat, a support frame, a beam arm and an inkjet device; a support frame is fixed on one side of the support seat, and a The beam arm is fixed; the bottom end of the heating plate is provided with an inkjet through the cover plate; the upper end of the support seat is provided with a cloth conveyor belt through the support rod, and the outer surfaces of both sides of the cloth conveyor belt are provided with fixed pins; There is an installation and pull-out unit on the top, and a fixed sleeve is arranged on the installation and pull-out unit; a fixing hole is opened on the fixed sleeve, and the fixed sleeve is sleeved on the fixed needle through the installation and pull-out unit; The combined use of multiple fixing pins and fixing sleeves can fix the elastic cloth, and at the same time prevent the elastic cloth from being stretched due to the excessive conveying force of the cloth conveyor belt, which will affect the printing effect of the inkjet on the elastic cloth.

The invention discloses an anti-wire-drawing 3D printing pen with adjustable diameter. The anti-wire-drawing 3D printing pen with adjustable diameter comprises a material guiding pipe, a hot melt chamber, a pen holder, throat pipes and a pen head. The hot melt chamber is formed in the bottom end of the interior of the pen holder, the material guiding pipe is disposed in the pen holder, the top endof the material guiding pipe extends to the top of the pen holder, the bottom end of the material guiding pipe is in communication with the hot melt chamber, and a heating pipe is arrange in the penholder of the outer side of the end, close to the hot melt chamber, of the material guiding pipe. The throat pipes are evenly spaced between the pen head and the pen holder, so that the surface area of the throat pipes can be utilized to increase the heat dissipation area of materials conveniently without affecting material circulation, and air can circulate between adjacent throat pipes, so thatthe printing pen is driven to move in the process of combining with the use of the printing pen; and the flow of the air between the throat pipes is further increased, the heat dissipation effect is improved, the solidification efficiency of the materials is improved, and the situation that the materials are excessively soft to affect the effect of printing in the process of printing is avoided.

The invention discloses a wire and cable surface printing device, which comprises a base, a driving mechanism is arranged on the top of the base, an ink filling mechanism is arranged on the top of the driving mechanism, and a cleaning mechanism is arranged on one side of the driving mechanism. A winding mechanism is arranged on the top of the base away from the cleaning mechanism, and a transmission mechanism is arranged between the ink adding mechanism and the driving mechanism. The present invention can clean the surface of the cable by setting a drive mechanism, an ink filling mechanism, a cleaning mechanism and a winding mechanism, and can print on the cable while winding, and can also continuously replenish ink to the printing wheel to prevent printing The printing is not clear due to too little ink.

The invention discloses a paper feeding box for a printer, and relates to the technical field of printer auxiliary equipment. The paper feeding box for the printer comprises a paper storage box, a paper feeding mechanism is fixedly installed on the inner side of the right end of the paper storage box, a dust suction mechanism is fixedly installed at the upper end of the paper feeding mechanism, a conveying roller is fixedly installed on the inner side of the left end of the paper storage box, the paper storage box comprises a paper outlet, a fixed clamping strip and a rotating plate, the paper outlet is formed in the upper end of the left side of the paper storage box, the fixed clamping strip is fixedly installed at the upper ends of the front face and the back face of the paper storage box, and the rotating plate is rotationally installed at the right end of the top of the paper storage box through a hinge. According to the paper feeding box for the printer, the paper feeding mechanism is arranged to be matched with the dust suction mechanism, the dust suction mechanism is driven by the paper feeding mechanism to work in the paper feeding box, dust on paper is adsorbed when fed into the printer, and the circumstance that the dust is attached to the printing face of the paper, and the printing effect of the printer is affected is avoided.

The invention provides preparation methods of modified carbon black and black chemical powdered ink. The preparation method of the carbon black comprises the following steps: (1) adding 5 to 30 parts by weight of carbon black to 100 to 500 parts by volume of concentrated acid; uniformly agitating; and controlling the temperature to be 30 to 70 DEG C to react for 2 to 6 hours; (2) adding 15 to 50 parts by weight of strong oxidant to the mixed solution obtained in step (1), and reacting for 1 to 3 hours in a water bath at 30 DEG C; and (3) agitating the mixed solution obtained in step (2), slowly adding deionized water, diluting, performing reduced-pressure suction filtration, and washing to obtain the modified carbon black. The black chemical powdered ink is prepared through such modified carbon black. Due to the adoption of the preparation methods, the problems of the prior art that the carbon black has poor wettability and is instable in an aqueous medium to further cause that the powdered ink is non-uniform in particle distribution and excessively wide in particle size, can be solved.
