(1) Nickel mesh: A hard and brittle nickel mesh is prone to twisting and breaking. A hard and tough nickel mesh should be used, which has good tensile, compression and mechanical resistance. For a nickel mesh of the same material, the higher the number of round meshes, the more meshes per unit area, the smaller the mesh, and the greater the strength of the circular mesh. Generally, the pattern is 31~39 mesh/cm (80~100 mesh), and the individual fine lines are 49 mesh/cm (125 mesh).
(2) Networking process: If the rotary screen is not properly operated during the preparation process, the flower net is not properly rounded, and the upper head is skewed, etc., it is bound to cause the network to be twisted or broken due to uneven compression and tensile stress. . To this end, the preparation of the flower net should be done in a round, good, clean, evenly coated, flat head, and tightly bonded.
(3) Equipment: After long-term operation, certain parameters of the equipment will change, individual components will age, and the static balance point of the host will change, which will increase the frequency of twisting and disconnecting. Improvement measures include: regular correction of static balance point and speed ratio of equipment; regular inspection of the transmission part of the equipment and the tightness of the belt, if there are hidden dangers, timely treatment; the correction of the rubber blanket to the deviation device in the case of normal operation of the equipment Accurate adjustment, reduce the probability of its left and right swing; regularly check the chuck, found that there is inflexible timely processing; regularly add the right amount of lubricant to the chuck.
(4) Operation: The main reasons and improvement measures for twisting and disconnecting the net due to improper operation are as follows:
1 improper adjustment of the height of the flower net: for this reason, it is advisable to adjust the height of the car before and after driving, so that the position of the support tube and the magnetic rod of the slurry tube are moderate, so that the two ends of the magnetic rod can be both supported. Hold it, and put some pressure on the net;
2 magnetic bar, magnetic selection is too large, or probe bar failure: the choice of magnetic bar, magnetic force should be based on the combination of flower printing effect, fabric thickness and so on;
3 color paste is unclean: the color paste used for printing should be clean, and there must be no hard impurities, and foreign matter is mixed inside;
4 improper tension adjustment: properly adjust the tension of the cloth to enhance the filtration of the color paste.
