Fiber carding and outputting device for air laid machine

Abstract

A fiber carding and outputting device for an air laid machine comprises a machine frame, a cotton pressing plate supported by a left wallboard and a right wallboard, an air bellow fixed between the left wallboard and the right wallboard, a cotton carding roller supported between the left wallboard and the right wallboard, a cotton supporting plate arranged under the cotton pressing plate correspondingly, and a roller mechanism supported between the left wallboard and the right wallboard and connected with a roller driving mechanism. The device is characterized in that an air outlet channel of the air bellow extends to a cotton outlet of the cotton carding roller and is connected with the front side of a guide plate on the cotton carding roller, and an airflow uniformizing plate is arranged at the position of an air outlet of the air outlet channel of the air bellow; the roller device comprises a large upper roller, a large lower roller, a small upper roller, a small lower roller and a pair of roller shaft adjusting bases, and the roller driving mechanism comprises a driving motor fixing base, a driving motor, a driving motor chain wheel, a large upper roller shaft chain wheel, a large lower roller shaft chain wheel, a small upper roller shaft chain wheel, a small lower roller shaft chain wheel, a transition tensioning chain wheel, a tensioning chain wheel and a driving chain. By the adoption of the device, it is ensured that the thickness of a non-woven cellucotton web layer is uniform, work strength is reduced, and safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a fiber carding and output device of an air-laid machine. Background technique [0002] The function of the air-laid machine is to form a cotton web from the non-woven fiber loosened by the opening device in the previous process, that is, the opening machine, and transport it to the shaping equipment in the subsequent process to shape it into such things as non-woven fabrics, thermal insulation materials, and sound insulation felts. , automotive interior parts, home bedding products (such as cushions) and other products. The aforementioned sizing equipment such as acupuncture machines and hydroentanglement machines. [0003] It can be seen from the above that the air-laid machine is located between the opening device and the setting equipment on the complete non-woven product production line. The air-laid machine uses a high-speed rotating carding roller...

AI Technical Summary

Problems solved by technology

Taking the aforementioned CN2663451Y and CN102373516B as examples, since the thickness of the fiber cotton web layer tends to be uniform through the suction of the dust cage, that is, the cotton pressing roller, it is essentially a measure that treats the surface rather than the root cause. On the premise that the previous fiber carding and output are not enough to ensure the fiber uniform effect, the suction of the subsequent station does not really achieve the consistent weight of the fiber cotton layer

[0009] In addition, the roller mechanism and the roller driving mechanism are also an important part of the structural system of the fiber carding and output device. In the prior art, many sprockets of the roller driving mechanism are usually fixed to the end of the roller shaft of the roller in an exposed state. Although the structural form is convenient for daily maintenance, it needs to be cleaned frequently because it is vulnerable to the invasion of non-woven fibers and fiber dust in the workplace, which not only increases the work intensity of equipment maintenance personnel, but also poses safety concerns
