Car carpet production line

Abstract

The invention provides a car carpet production line comprising a vertically arranged cotton delivering box, a pair of cotton delivering rollers rotationally arranged at the bottom of the cotton conveying box, a first conveying curtain arranged bellow the cotton delivering rollers, a second conveying curtain parallel with the first conveying curtain, a weighing device arranged between the first conveying curtain and the second conveying curtain and used for weighing cotton fibers, a cotton carding box for carding the cotton fibers and a pair of cotton feeding rollers for feeding the cotton fibers on the second conveying curtain into a cotton inlet of the cotton carding box, wherein the cotton feeding rollers are driven by a variable frequency motor to rotate, a control host is used for controlling the variable frequency motor and connected with a controller of the weighing device and a controller of the variable frequency motor respectively, and an anti-blocking device for preventing cotton blockage is arranged in the cotton delivering box. The speed of the rollers is controlled automatically according to the weight of fiber layers, so that the weight of fibers fed into a carding machine is stable, and the gram weight of final products is stable.

Description

technical field [0001] The invention relates to textile equipment, in particular to an automobile carpet production line. Background technique [0002] Car carpets have high requirements on product weight stability. The weight control of the original production line is to control the feeding amount of the fiber layer by the speed of the two pairs of rollers before entering the carding machine. This speed remains unchanged after the operator adjusts it. Due to the difference in elasticity, loose raw materials and tight raw materials are fed at the same speed, and the product weight is light or heavy. Stablize. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned technologies, thereby providing an automobile carpet production line, which automatically controls the speed of the rollers according to the weight of the fiber layer, so as to achieve stable fiber weight feeding to the carding machine and st...

Problems solved by technology

[0002] Automobile carpets have high requirements on product weight stability. The weight control of the original production line is to control the feeding amount of the fiber layer by the speed of the two pairs of rollers before entering the carding machine. This speed remains unchanged after being adjusted by the operator. Due to the difference in elasticity, loose raw materials and tight raw materials are fed at the same speed, and the weight of the product is lighter or heavier. The weight after debugging will change with the tightness of the fed raw materials, resulting in poor control of the weight of the product. Stablize
