The device effectively prevents the jamming of the lickerin sucker and is convenient for regulating the volume of the supplemented wind and propitious to impurity-removal. The device is characterized by simple structure, good universal capacities and is applicable to wide promotion and application in the textile mechanical field, in particular to the carding machine manufacturing enterprises.

Description

Carding machine waste removal device

technical field

The utility model belongs to the technical field of textile machinery, in particular to a carding machine waste removal device.

Background technique

During the working process of the cotton carding machine, when the licker-in roller drives the fiber to the dust removal knife, the impurities, short fibers and dust in the fiber are separated due to the stripping effect of the dust removal knife. If the separated substances are not removed, It will cause the machine not to operate normally.

At present, there is a kind of impurity stripped by the dust removal knife on the existing carding machine, which falls down to the space under the licker-in roller, and is removed from here. The suction pipe in this impurity area is insufficient: 1. It makes the removal complicated. 2. Impurities fall diffusely and therefore the entire lower space of the machine must be cleaned, resulting in impurities and air swirling everywhere.

There is also a carding machine impurity removal device (as shown in Figure 1), which is that the dust removal knife 3 is installed on a dust removal knife seat 31, and the dust removal knife seat 31 can move along the circumference of the licker-in roller 1 while driving the licker-in roller The suction pipe 4 moves, thereby causing the distance between the licker-in roller suction pipe 4 and the cotton feeding roller 2 to change, resulting in a change in the size of the air supply port 7 . In order to ensure that the size of the supplementary air port 7 remains basically unchanged, there is a fixed guide element 6 between the licker-in suction tube 4 and the cotton feeding roller 2. When the licker-in suction tube 4 moves, the cotton feeding roller 2 and the cotton feeding roller The vertical distance between 4 is basically constant, that is, the size of the air supply port 7 is constant. After the impurity 5 is stripped off by the dedusting knife 3, it is sucked away by the licker-in suction pipe 4, and the suction pipe in the impurity area is generally sucked at one or both ends of the licker-in suction pipe 4, and finally the impurity 5 passes through the port of the licker-in suction pipe 4 into the dust filter system. The disadvantages of the suction pipe in the trash area are: 1. When the dust filter pressure is low or the dust removal knife has burrs, the suction pipe of the licker-in roller is too small to absorb impurities. With the accumulation of impurities, the suction pipe of the licker-in roller will often be blocked. 2. The supplementary air volume of the suction pipe in the miscellaneous area cannot be adjusted.

In order to solve the above-mentioned technical problems, it is urgent to improve the trash removal device of the carding machine.
