1. The installation accuracy of the printing part of the rotary screen printing machine. The biggest relationship with the broken net is the beam part of the printing machine of the rotary screen printing machine. The horizontalness, parallelism, straightness of the beam, the height of the beam and the height of the pressure roller, etc., large assembly error, the nickel mesh in the rotating grid The gear meshing gap between the gear and the gearbox is too large to produce slippage, the gear ratio of the gear is not constant, and the linear velocity of the nickel mesh and the linear speed of the rubber guide tape are not synchronized, etc., which may cause escape or disconnection. Therefore, the installation accuracy of the printing machine equipment is very important.
2. The rotary screen printing machine increases the air pressure regulation. If the control gas path of the up network is faulty, the pressure regulating valve fails, the valve is leaking, the cylinder is leaking, the pipe is broken, etc., the air pressure will be reduced, causing the nickel mesh to have insufficient force and cannot withstand a certain torque. A broken network is generated. If the surface of the beam is stained with dye or passive mesh header, there will be dirt in the groove, which will cause the head frame to not move smoothly on the beam, which will reduce the tension of the nickel mesh and cause a broken mesh.
3. Nickel mesh breakage and repair of the headstock beam. The nickel mesh is rotated by the gearbox of the reduction gearbox, the support of the active headstock and the passive headstock bearing. The lack of oil in the passive head frame causes the bearing to be damaged and jams, which may cause the network to break. On the other hand, in the installation or repair of the Open Type Rotary Screen Printing Machine , the horizontal and horizontal levels of the beam, the height of the beam and the frame are not adjusted well, and the meshing gap between the gear box gear and the active grid gear is too large, causing the transmission The ratio is not constant, so that the linear velocity of the rotation of the nickel mesh is not synchronized with the linear velocity of the conduction band, and disconnection and pattern blurring may occur.
