Ultra-large plastic circular loom

Abstract

The invention discloses an ultra-large plastic circular loom, and belongs to the technical field of weaving machines. The ultra-large plastic circular loom comprises a main loom, a warp frame, a warp conveying device, a cloth lifting device and a cloth coiling device, wherein the warp frame is arranged on the periphery of the main loom, the warp conveying device is arranged between the main loom and the warp frame, the main loom comprises a driving device and a main shaft connected with the driving device, shutters are arranged on a support of the main loom, a cam is fixed to the main shaft, two annular grooves extending in the circumferential direction are formed in the outer cylindrical face of the cam, the unfolding shapes of the two annular grooves are both sine curves in seven periods, the phase difference between the two sine curves is 180 degrees, and the number of the shutters is fourteen. The ultra-large plastic circular loom can be provided with fourteen shutters, fabric with a larger fold diameter can be woven, and energy consumption is low.

Description

technical field [0001] The invention relates to a weaving machine, in particular to a plastic circular loom. Background technique [0002] Now commonly used circular looms include hyperbolic small cam large circular looms and single curved large cam brown belt structure super large circular looms, among which the hyperbolic small cam large circular looms have a maximum braiding diameter of 3200mm and are equipped with 10 The shuttle is mainly used in the production of large tipping bags, geotextiles, and large plastic tarpaulins. Due to the small diameter of the cam, the required driving power is small, so the energy consumption is small. However, due to the limitation of the cam structure, this kind of circular loom can only Equipped with 10 shuttles, it is impossible to weave fabrics with larger folding diameters. However, the super-large circular loom with a single-curve large cam brown belt structure has a maximum braiding diameter of 4000mm and is equipped with 12 shut...

[0002] Now commonly used circular looms include hyperbolic small cam large circular looms and single curved large cam brown belt structure super large circular looms, among which the hyperbolic small cam large circular looms have a maximum braiding diameter of 3200mm and are equipped with 10 The shuttle is mainly used in the production of large tipping bags, geotextiles, and large plastic tarpaulins. Due to the small diameter of the cam, the required driving power is small, so the energy consumption is small. However, due to the limitation of the cam structure, this kind of circular loom can only Equipped with 10 shuttles, it is impossible to weave fabrics with larger folding diameters

However, the super-large circular loom with a single-curve large cam brown belt structure has a maximum braiding diameter of 4000mm and is equipped with 12 shuttles. Due to the large diameter of the cam, the required driving force is also large and the energy consumption is high; in addition, the existing circular loom The yarn is fed from both sides. On the one hand, because each creel needs to provide warp yarns in a 180-degree semicircle for the main machine, the route of the warp yarns from the creel to the main machine is very different, resulting in uneven distribution of warp tension. The larger the machine, the tension The more obvious the unevenness is, it will seriously affect the product quality. On the other hand, the yarn feeding arrangement on both sides will inevitably cause the size of parts such as the yarn feeding rod to be too long, making it difficult to guarantee the processing accuracy and avoid deformation during use, thus affecting the accuracy of the equipment and product quality
