Description

Technical Field

[0001] The utility model belongs to the technical field of carding machines, and particularly relates to a rear zone carding structure of a novel carding machine. Background Technique

[0002] At present, the rear zone carding method of the carding machines used and manufactured by various textile factories and carding machine manufacturers is: the scheme of fixed flats plus a cotton web cleaner, and the number of rear fixed flats is configured from 2 to 10 according to different models of the carding machine.

[0003] The carding area of the rear fixed flats of the carding machine mainly refers to the carding section between the rear fixed flats, the cotton web cleaner, the rear upper cover plate, the rear lower cover plate and the cylinder, which is both a pre-carding area and a impurity removal area. This carding area enters from the rear lower cover plate and exits from the rear upper cover plate, and there are carding between the cylinder and the rear fixed flats, impurity discharge between the cylinder and the dust knife, and air flow control and diversion processes between the cylinder and the air flow guide cover plate.

[0004] Advantages and functions of the fixed flats: Since there are still a small number of fiber bundles in the fiber layer after the licker-in carding that have not been loosened, when the single output of the carding machine is increased, the carding effect will be weakened to some extent. In order to increase the output on the premise of ensuring quality, rear fixed flats are installed at the rear cover plate position, so that the fibers transferred from the licker-in to the cylinder are pre-carded once before entering the working area of the movable flats, the fiber arrangement direction on the cylinder tooth surface entering the working area of the movable flats is improved, the fiber bundles are decomposed and loosened, and the load on the movable flats in the working area is reduced. The design requirements for the saw teeth of the rear fixed flats are: the fixed flats are not filled with fibers, do not hang flowers, and can pre-card the fibers to achieve the purpose of reducing fiber bundles and not damaging the fibers.

[0005] However, the following problems still exist at present:

[0006] 1. Installation accuracy problem: The installation accuracy directly affects the process effect. Since there are many domestic carding machine manufacturers and the quality levels are uneven, for some carding machines with poor accuracy, it is difficult to ensure the installation accuracy when installing fixed flats, and the process effect cannot be achieved, but instead has a counterproductive effect.

[0007] 2. The phenomenon of spraying flowers on the rear fixed flats of the carding machine occurs frequently, and the following phenomena often exist:

[0008] 1). High dust content in cotton: If the cotton contains a large amount of dust and impurities, these particulate matters will accumulate on the fixed flats, forming dust or spots. The solution is to improve the cleaning efficiency of the cotton and reduce the dust content.

[0009] 2). The surface of the fixed flats is uneven: If the surface of the fixed flats is uneven or there are problems such as wear and scratches, the fibers in the cotton are easily stuck, resulting in flying hairs. The solution is to replace or repair the fixed flats.

[0010] 3) Loose installation of the fixed cover plate: If the fixed cover plate is not installed in place or firmly, it is likely to shake or become detached during the carding process, resulting in spraying. The solution is to check the installation of the fixed cover plate to ensure it is firmly fixed.

[0011] 4) Excessive speed of the carding machine: During the carding process, if the speed of the carding wheel is too high, it will generate a large amount of airflow and pressure, thus blowing the cotton apart and causing spraying on the fixed cover plate.

[0012] The rear fixed cover plate of the carding machine often has the following problems during use due to its high precision requirements and high requirements for the technical capabilities of users:

[0013] The cylinder card clothing is squeezed and damaged into a horizontal spiral state, and it appears continuously for nearly a week.

[0014] The fixed cover plate is damaged and the needle teeth are disengaged.

[0015] Using a fiber optic microscope to observe the tips and back edges of the teeth of the cylinder and the fixed cover plate, there are phenomena of twisting and slight damage.

[0016] During operation, the rear fixed cover plate vibrates, makes abnormal noises, and has abnormal heat generation with a temperature rise exceeding 40°.

[0017] The state of the cover plate waste is uneven, there are many bundle-shaped fibers, and the thickness distribution of the cover plate waste is uneven.

[0018] The carding effect is poor and the number of neps increases.

[0019] The process gauge in the carding area is too tight, the fibers are rubbed, the geometric dimensions of the fixed cover plate card clothing affect fiber transfer, the opening effect at the rear of the licker-in is poor, the carding load is aggravated, the raw material contains a lot of impurities and defects, the exclusion ability is limited, and the process design of the back shroud is unreasonable, resulting in lateral airflow movement. Summary of the Invention

[0020] The purpose of the present invention is to provide a rear area carding structure for a new type of carding machine to solve the problems of many limitations in the use of the fixed cover plate mentioned in the above background technology.

[0022] Preferably, the working roller and the stripping roller are both connected to a driving motor with a frequency converter, always maintaining a reasonable speed, and separating the excessively thick fiber layer, as well as the grouped and bundled fibers into single fibers. Compared with the transmission fixed cover plate embedded in the surface of the cylinder, in a stationary state, and passively combing the fibers, the dynamic and flexible opening of the entire combing roller can effectively protect the fibers and reduce damage, especially for special fibers with poor strength and long length. The effect is obvious. The diameter of the working roller is larger than that of the stripping roller.

[0023] Preferably, the mounting portion is a small wall panel, a transmission system is installed on the top of one side of the small wall panel, the transmission system is electrically connected to the drive, the working roller, stripping roller, and opening roller are all installed on the small wall panel through a support frame, and the small wall panel is arranged on the outside of the end of the cylinder.

[0024] Preferably, it also includes a feed roller grip and a licker-in roller, wherein the licker-in roller is arranged at the bottom of the opening roller, and the licker-in roller is tangent to the cylinder, and the feed roller grip is located outside the licker-in roller, and the fibers are conveyed via the feed plate and the feed roller grip, at which time the raw fiber is in an initial state, the single fibers in the fiber layer are disorderly, accompanied by clumps or bundles of fiber clumps, which are roughly opened by the licker-in roller, and the fiber layer is transferred to the surface of the cylinder, and then processed by the combing roller.

[0025] Preferably, protective covers are installed on the outside of the working roll, stripping roll and opening roll, wherein the working roll and stripping roll share one protective cover, and the construction safety is improved by the protective cover.

[0026] Preferably, a suction hood is also provided on the top of the working roller, and a movable cover plate tangent to the cylinder is also provided on the top of the suction hood. The movable cover plate can straighten the fibers, transfer them to the straight three-roller cotton stripping device through the doffer, and form them into strips through the three-roller cotton stripping device, thereby completing the combing task.

[0027] Preferably, a material inlet for fibers to enter is reserved at the bottom held by the feed roller, and the licker-in is on the extension line of the material inlet.

[0028] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0029] Through the transformation of the carding roller, the loosening of the fibers at the initial end of the back zone is increased, the orientation degree of the fibers is improved, the fiber state of the fixed flat after feeding into the cylinder is improved, and the probability of card clothing damage is reduced. The carding area in the initial area of the cylinder and the back fixed flat is the place where the fiber layer is the thickest. The gauge here should not be too tight. Therefore, canceling the fixed flat and replacing it with a carding roller can effectively prevent the fibers from flipping, rubbing or squeezing into the tooth gaps of the cylinder and the fixed flat in this area, causing damage to the card clothing.
