Description

Technical Field

[0001] The utility model embodiment relates to the technical field of circular knitting machines, and in particular to an electrostatic dust removal device for a circular knitting machine. Background Art

[0002] Knitted fabrics are knitted fabrics formed by feeding yarns from the weft direction to the working needles of the circular knitting machine through the yarn feeding nozzle, so that the yarns are bent into loops in sequence and interlaced with each other in the longitudinal direction. The knitted fabrics are pulled to the cloth winding machine and wound into rolls by the cloth winding machine.

[0003] A large number of knitting needles are arranged in the mounting groove on the surface of the needle cylinder, which is a rotating part in the circular knitting machine. Similarly, the same number of Schenck plates are evenly arranged in the Schenck circle groove. The two elements respectively use the weaving triangle assembly and the track triangle located at the Schenck circle position to weave the yarn input from the yarn feed nozzle into the final fabric according to certain weft knitting rules.

[0004] The inventors of the present application have discovered that broken yarns, cotton wool, dust and other debris are often attached to the surface of the knitting yarn, and that a large amount of flying wool is generated due to contact friction during the process of the yarn being conveyed to the through hole of the yarn feeding nozzle and fed into the hook of the knitting needle. When the yarn is woven into cloth, the broken yarns, cotton wool, dust and flying wool on the yarn will adhere to the surface and inside of the knitted cloth, affecting the quality of the cloth; and flying wool, dust and other debris adhere to the parts of the circular knitting machine, affecting the normal operation of the circular knitting machine.

Similarly, the same number of Schenck plates are evenly arranged in the Schenck circle groove. The two elements respectively weave the yarn input from the yarn feeding nozzle into the final fabric through the weaving triangle assembly and the track triangle located at the Schenck circle position according to certain weft knitting rules.

[0041] The inventors of the present application have discovered that broken yarns, cotton wool, dust and other debris are often attached to the surface of the knitting yarn, and that a large amount of flying wool is generated due to contact friction during the process of the yarn being conveyed to the through hole of the yarn feeding nozzle and fed into the hook of the knitting needle.

[0042] In order to solve the above problems, the inventor of the present application proposed the technical solution of the present application, and the specific embodiments are as follows:

[0044] like Figures 1 to 5 As shown, the electrostatic dust removal device for a circular knitting machine of this embodiment includes: an anode collector 1, a cathode assembly 2, a storage box 3 and a DC power supply.

By changing the voltage value of the DC power supply, the electric field strength can be changed. When the electric field strength is close to the breakdown electric field strength of the air, the air is ionized, and a large number of positive ions and free electrons are formed between the anode collector and the cathode rod. Under the action of the electric field, the free electrons move toward the anode collector, and collide with neutral molecules or particles in the air during the movement. The particles such as flying catkins and dust in the air become charged particles after absorbing electrons, so that the neutral flying catkins, dust, etc. are negatively charged.
