Description

Technical Field

[0001] The utility model relates to the technical field of carding machine cover plates, in particular to a fixed cover plate positioning component of the carding machine. Background Art

[0002] The main function of the movable flat of the carding machine is to comb, remove impurities, mix and remove most of the cotton knots, impurities and short fibers during the cleaning and carding process. The fixed flat of the carding machine, the cotton net cleaner, the movable flat and the spacing between the cylinder card clothing of the carding machine are very important for the quality of carding. The function of the fixed flat is to pre-comb the large cotton bundles before entering the main combing area of ​​the cylinder and the movable flat, and to post-process the fibers after passing through the main combing area of ​​the cylinder and the movable flat, so as to improve the parallelism of the fibers. For example, a cotton carding machine fixed cover adjustment device proposed by the Chinese patent with announcement number CN203768524U needs to loosen the second locking nut and the third locking nut first, and then rotate the first adjusting bolt and the second adjusting bolt respectively to conveniently adjust the distance between the fixed cover and the curved rail, thereby adjusting the distance between the fixed cover and the cylinder, thereby ensuring that it has a good combing effect. After the adjustment is completed, the second locking nut and the third locking nut can be tightened; and when the fixed cover is tilted before and after, the position of the fixed cover can be returned to the center by controlling the first adjusting bolt and the second adjusting bolt to rotate different numbers of circles; the positioning bolt and spring are provided so that the fixed cover does not shake when rotating, so that its positioning is reliable and the distance between the fixed cover and the curved rail can be conveniently adjusted, thereby adjusting the distance between the fixed cover and the cylinder, thereby ensuring that it has a good combing effect. This results in the need to use tools to rotate the locking nuts multiple times during the adjustment process, which is time-consuming and labor-intensive to adjust, inconvenient to operate, and the reciprocating adjustment increases the probability of nut damage, making the locking effect unstable. To this end, the utility model proposes a fixed cover positioning assembly for a carding machine. Utility Model Content

Two slots 6 are provided on the inner side of the base 5, and the slots 6 are symmetrically arranged; a distance piece 7 is clamped on one side of the base 5, and the bottom surface of the distance piece 7 is an arc-shaped structure, which can make the bottom surface of the distance piece 7 close to the curved rail 1, and a second bolt 8 is provided with a thread passing through the distance piece 7, and the lower end of the second bolt 8 is fixedly connected to the curved rail 1, which can stably fix the distance piece 7 on the curved rail 1, and a pressing groove 9 is provided on the upper surface of the distance piece 7; a positioning component 10 for limiting the curved rail 1 is threaded on the connecting block 3, and the positioning component 10 is located directly above the pressing groove 9.

[0027] like Figure 1 and Figure 4 As shown, the positioning assembly 10 includes a third bolt 101, and a sliding groove is provided at the lower end of the third bolt 101. The lower end of the third bolt 101 is movably connected to a movable ring 102. The outer wall of the movable ring 102 is hingedly provided with a group of connecting rods 103, and the connecting rods 103 are symmetrically arranged. One end of the connecting rod 103 is hingedly connected to an insert block 104, and the insert block 104 can be movably inserted into the slot 6.

[0028] Furthermore, the positioning assembly 10 also includes a fixed rod 105 movably sleeved inside the movable groove at the lower end of the third bolt 101, which can enable the fixed rod 105 to slide vertically stably. The lower end of the fixed rod 105 is fixedly connected to a pressure block 106, and the pressure block 106 can be clamped with the pressure groove 9 on the upper surface of the spacing plate 7.
