The utility model relates to a flat push type printing paper with lock code tearable edge, which is made of carbonless copy paper material, characterized in that it adopts a structure scheme of one upper paper layer, 0-6 middle paper layers and one lower paper layer, and the four edges are cut flush, and the two edges are riveted with lock code and pressed with tearable lines, and the pressure-sensitive color display characteristics of carbonless copy paper are used to realize simultaneous color display of multiple paper layers in a single printing process; compared with traditional continuous format carbonless copy computer printing paper, the structure is simple, and users do not need to manually tear and separate single copies, so that the product is more convenient to use and has low cost; the self-releasing paper material with waterproof film coated on both sides of the upper paper, middle paper and lower paper can effectively prevent moisture, and is suitable for use in humid or outdoor construction.

The utility model discloses a carbonless copy paper processing wind-up roll positioning support which comprises a wind-up roll, an air cylinder and a sliding table formed by assembling a bidirectional lead screw and a transmission shaft, the sliding table is provided with a pair of sliding seats in a sliding mode, the sliding seats are connected with the bidirectional lead screw in a threaded mode, one end of each sliding seat is provided with a guide plate in a rotating mode, and one side of each sliding seat is connected with a shifting rod in a rotating and sleeved mode. The deflector rod is in key connection with the transmission shaft, one end of the guide plate extends to be in contact with the winding roller, the other end of the guide plate is fixedly provided with a limiting rod, the deflector rod is provided with a sliding hole for containing the limiting rod, and the end of the transmission shaft is fixedly provided with a swing arm; the cylinder is matched with the deflector rod through the swing arm to drive the guide plate to rotate until the end part is far away from the winding roller. The pair of guide plates is located on the two sides of paper to guide and restrain paper rolling, after paper rolling is completed, the guide plates are turned over, and it is guaranteed that rotation of the rolling roller body is not hindered during discharging through mechanical locking of the limiting rods and the shifting rods.

The utility model relates to production equipment for single-copy multi-copy printing paper. The production equipment is characterized by comprising a plurality of sets of uncoiling seats, a deviation rectifying device, a marking device, an easy-to-tear line cutting device, a lock code pressing device, a pressed paper conveying device, a cutting device, a separation conveying device, a superposition conveying device, a vibration paper collecting table and a control system which are arranged in sequence, according to the production equipment, roll type carbonless copy paper is adopted as a raw material for continuous production, turnover of middle semi-finished products is reduced, and the production efficiency is improved; the paper cutting length is accurate, a finished product can be directly produced, secondary accurate cutting is not needed, working allowance does not need to be reserved, the processing loss of a traditional production mode is reduced, and the technical problems of high efficiency and low loss in production of single carbon-free copying printing paper are solved.

The utility model discloses a carbonless copy paper guide roller convenient to disassemble and assemble, which belongs to the technical field of paper guide rollers and comprises a bottom plate, a mounting seat is mounted at the top of the bottom plate, a sliding groove is formed in the outer wall of the right end of the mounting seat, a lifting assembly is mounted between the inner wall of the sliding groove and the top of the mounting seat, and the lifting assembly is connected with a mounting pipe. A baffle disc is mounted on the outer wall of the left end of the mounting pipe, a paper guide roller is connected to the outer wall of the mounting pipe in a sleeving mode, carbon paper is wound on the outer wall of the paper guide roller, a limiting groove is formed in the side wall of the right end of the mounting pipe, and through interaction of the paper guide roller, a limiting assembly, the limiting groove, a sliding block, the mounting pipe, a second spring and other assemblies, the carbon paper is wound on the outer wall of the paper guide roller. The paper guide roller can be rapidly disassembled and assembled and can be stably limited by the limiting assembly, meanwhile, the lifting assembly can automatically control the paper guide roller to move up and down according to needs, and the flattening assembly can conduct auxiliary flattening on the outer wall of review paper all the time.

The utility model discloses a carbonless copy paper coating liquid supply stirring device which comprises a tank body, a stirring paddle and a defoaming assembly, the defoaming assembly comprises a tray movably installed in the tank body, a floating disc is fixedly installed at the bottom of the tray, and a plurality of defoaming thorns used for puncturing foams are integrally formed on the tray. The connecting rod, the bottom ring, the top plate and the tray are matched to form the floating disc assembly in the tank body, the tray can directly act on a foam layer of coating liquid along with fluctuation of the liquid level, shearing force generated by high-speed rotation of the stirring paddle is matched with the defoaming thorns at the bottom of the tray to eliminate defoaming, so that the coating liquid flows more smoothly, stirring is more uniform, and the coating effect is better. Therefore, the coating liquid can be uniformly covered on the surface of the paper during coating, and the coating quality of the carbon paper is improved.
