Description

Technical Field

[0001] The utility model relates to the technical field of plastic woven bags, in particular to a circular loom for plastic woven bags. Background Art

[0002] Circular loom is a kind of textile machinery, mainly used for weaving circular fabrics, such as tubular cloth, tubular knitted fabrics, etc. Its working principle is to wind the warp yarn around the weft yarn according to a certain pattern, and through the crossing and reversing of the weft yarn, the interweaving and texture of the fabric are formed. Circular loom is characterized by high efficiency, stability and flexibility. It can produce circular fabrics of various specifications and materials, and is widely used in packaging, decoration, construction and other fields.

[0003] At present, in the prior art, a Chinese patent with announcement number CN213870931U discloses a circular loom for producing plastic woven bags. The device has a bidirectional shock-absorbing function through the design of a first buffer energy-absorbing block, a second buffer energy-absorbing block, a push block, an elastic rubber rod and a second support spring, thereby greatly weakening the vibration feeling, so that the device can maintain stable operation for a long time. However, in actual use of the device, the circular loom may have dust accumulation problems during long-term use. The dust accumulation will not only affect the normal operation of the machine, but may also cause damage to the machine, thereby affecting production efficiency. In view of this, we propose a circular loom for plastic woven bags. Utility Model Content
