Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carding machine equipment, in particular to a chest cylinder sealing plate. Background Art
[0002] In the carding machine, the sealing plates on both sides of the chest cylinder mainly play the role of sealing and preventing fiber scattering. After long-term contact with the high-speed rotating chest cylinder, especially under high fiber flow conditions, the sealing plates are extremely susceptible to friction and wear. However, the current sealing plates are mainly formed in one piece through casting, and need to be replaced as a whole when replacing parts, which increases maintenance costs. During the carding process of the carding machine, especially when the fiber length is long or the impurity content is high, the fibers tend to accumulate in the gap between the sealing plate and the chest cylinder. The accumulated fibers may cause the sealing plate to be unable to fit the chest cylinder properly, reducing the sealing effect, and a cumbersome disassembly process is required to clean the accumulated fibers, which makes cleaning and maintenance difficult. Utility Model Content

One side of the second sealing plate is connected to the first sealing plate, and the other side is connected to the third sealing plate. A plurality of brackets are fixed on the first sealing plate, and a snap-in hole is provided between the second sealing plate and the third sealing plate.
[0006] Furthermore, the first sealing plate is in a semicircular shape and has a through hole adapted to the rotating shaft of the breast cylinder.
[0007] Furthermore, the second sealing plate and the third sealing plate are both arc-shaped, the top edge of the second sealing plate is irregular, and the bottom edge of the third sealing plate is irregular.
[0008] Furthermore, a plurality of working rollers and stripping rollers are arranged on the chest cylinder, and the ends of the rotating shafts of the working rollers and stripping rollers are sleeved with shaft sleeves, and the shaft sleeves are connected to the bracket.
[0009] Furthermore, the shaft sleeve rotates relative to the rotating shafts of the working roller and the dehairing roller.
[0010] Furthermore, the second sealing plate has a plurality of first arc-shaped openings, the third sealing plate has a plurality of second arc-shaped openings, and the engaging hole is formed by correspondingly connecting the first arc-shaped openings and the second arc-shaped openings.
[0011] Furthermore, the shaft sleeve includes a first connecting section and a second connecting section, and a diameter of the first connecting section is smaller than a diameter of the second connecting section.
[0012] Furthermore, the engaging hole is adapted to the first connecting section, and the bracket is detachably fixedly connected to the second connecting section.
