Description

Technical Field

[0001] This utility model belongs to the field of carding machine technology, specifically referring to an anti-deformation cotton web cleaner. Background Technology

[0002] The cleaning function of the cotton web cleaner in the carding machine is to clean the cotton web, remove impurities, and remove short fibers. Adjusting the distance between the cotton web cleaner and the cylinder is the key to cleaning, removing impurities, and removing short fibers. By utilizing the changes in airflow on the boundary layer of the cylinder at the suction port of the cotton web cleaner, and under the dust removal action of the dust removal knife (or equivalent dust removal knife) at the inlet of the cleaner's suction port, the fiber flow in the boundary layer of the cotton web of the cylinder is separated from impurities and short fibers.

[0003] Therefore, the cleaning effect of the cotton web cleaner on the carding machine is related to the width of the air inlet, the distance between the air inlet mask plate and the cylinder, the distance between the dust removal knife and the cylinder, and the negative pressure of the air inlet. The cotton web cleaner is a major component of the cotton web cleaning process, and it plays an important role in fixing the dust removal knife and ensuring the distance between the dust removal knife and the cylinder and the width of the air inlet.

[0004] Because of its complex shape and precision requirements, most existing technologies use aluminum alloy extrusion molding. As the cylinder width increases, the weak resistance of aluminum profiles to heat deformation and shearing limits the functions of cotton web cleaning, impurity removal, and short lint removal. The deformation of the aluminum material can easily cause changes in the distance between the dust removal knife and the cylinder, which can seriously cause the dust removal knife and the cylinder needle cloth of the cotton web cleaner to collide and rub against each other, damaging the dust removal knife and the cylinder needle cloth and affecting the combing and dust removal effect. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides an anti-deformation cotton web cleaner, which solves the problems of thermal deformation and weak shear resistance of the cotton web cleaner on wide-width carding machines by adopting aluminum alloy profiles and refined steel supports.

[0006] The technical solution adopted in this utility model embodiment is as follows: an anti-deformation cotton net cleaner includes a support frame, an aluminum profile and a dust removal knife, wherein the aluminum profile is fixedly connected to the support frame and the dust removal knife is connected to the aluminum profile;

[0007] The support frame is made of carbon fiber or stainless steel, and the aluminum profile is made of aluminum alloy.

[0008] Furthermore, the support frame is L-shaped, and the aluminum profiles are respectively attached to the inner sidewalls of the support frame, and the aluminum profiles are connected to the support frame by adhesive.

[0009] Furthermore, the support frame includes an integrally formed vertical plate and a horizontal plate, and the vertical plate is provided with multiple through holes;

[0010] The aluminum profile has multiple threaded grooves at positions corresponding to the through holes.

[0011] Furthermore, it also includes multiple screws, which are threaded through the through holes and connected to the corresponding threaded grooves.

[0012] Furthermore, the through holes are evenly distributed in two rows on the vertical plate. The screws that mate with the upper row of through holes are countersunk screws, and the screws that mate with the lower row of through holes are flathead screws.

[0013] Furthermore, a through groove is provided in the aluminum profile below the dust removal blade, and an iron strip is provided in the through groove. The iron strip is fixedly connected to the dust removal blade and is connected to the aluminum profile by connecting screws.

[0014] Furthermore, the top of the aluminum profile is provided with a through hole, and a limiting element made of composite plastic is provided in the through hole. The limiting element is connected to the through hole of the aluminum profile by adhesive or screws.

[0015] The beneficial effects of this utility model by adopting the above structure are as follows:

[0016] This invention utilizes the advantages of easy forming and high precision of aluminum alloy profiles, and the strength and shear resistance of steel, to solve the problem of poor dust removal effect caused by changes in the spacing between the dust removal blade and cylinder due to the heat deformation and poor shear resistance of aluminum alloy profiles in cotton web cleaners.
