Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of high-efficiency needle bed cooling system for knitting machines, and in particular to a high-efficiency needle bed cooling system for knitting machines. Background Technology
[0002] Circular knitting machines, also known as circular weft knitting machines (or circular weft knitting machines), have seen rapid development due to their numerous loop-forming systems (commonly referred to as yarn feed paths or loop formation paths, or simply paths), high speeds, high output, rapid pattern changes, good fabric quality, fewer processing steps, and strong product adaptability. When yarn is drawn out from the needle cylinder and passes through a yarn guide before entering the circular knitting machine, it often carries lint and dust. This lint can easily cause needle jams, leading to yarn breakage and a decline in fabric quality.
[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content
[0004] A high-efficiency needle bed cooling system for a knitting machine includes a circular knitting machine with a needle bed inside. Several suction plates are arranged in a ring around the needle bed on the circular knitting machine. The suction plates are connected to a cooling fan through pipes. The cooling fan ventilates and cools the needle bed by drawing air from or blowing air onto the suction plates.
[0005] Preferably, a hollow support column is fixedly provided on the large circular knitting machine, and the suction plate is assembled on the hollow support column.
[0006] Preferably, the suction plate has a plurality of breathable mesh holes spaced apart on the side facing the needle bed of the large circular knitting machine, and the suction plate is connected to the hollow support column.
[0007] Preferably, the hollow support column is connected to the air duct, and the air duct is connected to the cooling fan.
[0008] Preferably, the large circular knitting machine is further provided with a filter cartridge compartment, which is connected to the cooling fan. The air duct is first connected to the filter cartridge compartment and then connected to the cooling fan through the filter cartridge compartment.
[0009] Preferably, the filter cartridge compartment is provided with a replaceable dust removal filter cartridge, and the upper port of the filter cartridge compartment is provided with a threaded cover plate.
[0010] The advantages and positive effects of this utility model are:
[0011] 1. It can dissipate heat through airflow during the operation of the knitting machine, and absorb floating fibers through air suction, effectively reducing the accumulation of floating and lint, making the knitting process cleaner. Attached Figure Description
