The utility model discloses a chamfer correcting device of a bending machine, which comprises a panel, symmetrical bearing plates are movably connected onto the panel, rotating motors are correspondingly and fixedly connected onto the bearing plates, a slot is arranged on the panel, a movable plate is movably connected into the slot, a plurality of bases are fixedly connected at the lower end of the panel, and the bases are fixedly connected with the rotating motors. Symmetrical guide rails are fixedly connected to the side face of the open groove, symmetrical limiting grooves are formed in the movable plate, symmetrical threaded shafts are movably connected between the synchronous motors, symmetrical threaded holes are formed in the movable plate, a guide motor is movably connected into the movable plate in a penetrating mode, and a mounting groove is formed in the side face of the rotating rod. By means of the structure, the chamfering requirements of materials of different specifications are met, it is guaranteed that the chamfering position is accurate, the machining efficiency and precision are improved, deviation during machining is prevented, disassembly and replacement are convenient, the maintenance cost is reduced, equipment cleanliness is guaranteed, and the service life is prolonged.

The application relates to the technical field of letterpress printing, in particular to a one-way driving device for film processing, which is characterized in that a one-way bearing is connected with a first driving motor and an oil absorption roller, independent driving of the first driving motor and the oil absorption roller is realized, the first driving motor is connected with the oil absorption roller through the one-way bearing, rotation of the oil absorption roller is no longer dependent on existence of a transmission assembly, the first driving motor independently drives the oil absorption roller to continuously rotate, and the situation that oil on the surface of the oil absorption roller is dried due to long-time static because the transmission assembly cannot transmit the rotating motion to the oil absorption roller is reduced; when the transmission assembly normally operates, the first driving motor does not operate, and the one-way transmission characteristic of the one-way bearing blocks reverse torque of the oil absorption roller from being transmitted to the first driving motor, so that the probability of reverse damage of the first driving motor is reduced.

A system for printing documents and anti-forgery security papers especially banknotes is provided. The system includes a mechanical feeding mechanism, a hologram pattern print section, an invisible, fluorescence color and main colors pattern printing section using at least three units of ink jet, a varnish coating section, a rotating cylindrical silkscreen printing section for optical variable ink (OVI), a raised printing section, a delivery section, a paper and handle receiving section and a central computer control section. The system has been introduced to create various security features in securities wherein all of the processes including the raised printing are introduced in an all-in-on device.

This utility model relates to the technical field of letterpress printing, and in particular to a letterpress printing drying device, including a printing machine body. A mounting box is welded to the top of the printing machine body, and a flow-diverting component is provided on the top wall of the mounting box. Oscillating blade components are provided on both sides of the mounting box. This utility model divides the drying area into independent air ducts using three sets of partitions. With the addition of branch air ducts and airflow regulating valves, local airflow can be finely adjusted for different printing areas. Reducing the airflow at the edges of the printed pattern effectively prevents ink from splashing due to excessive airflow impact, avoiding blurred edges or ink stains. An electric actuator drives a connecting column, causing a rack to slide back and forth. Through gear and shaft transmission, the oscillating blades achieve an "S-shaped" sweeping airflow. This path breaks the traditional fixed-point airflow impact mode, allowing hot air to dynamically cover the printing surface, avoiding ink accumulation or uneven drying caused by excessive local airflow pressure.

Based on a different principle than conventional products, we provide clothing and textiles that can resolve disruptions in bioelectric currents, normalize blood flow, increase and activate blood flow within the skin, improve the circulation of bodily fluids, and alleviate various physical ailments such as stiff shoulders and neck, and muscle pain, more effectively than conventional products. [Solution] A nanodiamond-containing garment characterized by having a nanodiamond solution attached to the body-contacting side, back side, or both sides of the garment by inkjet printing, silkscreen printing, letterpress printing, adhesive pressing, iron-on transfer method, handwriting, brush writing, or impregnation dyeing method.
