[0002] The carding machine is used to comb cotton blocks and bundles into single fibers, remove impurities such as leaf debris and seed debris contained in the raw cotton, comb out short fibers and cotton knots, mix the fibers, and make cotton strips for subsequent processing. The feeding mechanism of the traditional carding machine includes feeding rollers, feeding plates, licker-in rollers, dust removal knives, small leak bottoms, etc. The fibers fed by the feeding rollers and feeding plates are grabbed by the licker-in rollers, passed through the first drop zone, dust removal knives, the second drop zone and the small leak bottom, and then transferred to the cylinder for carding.

[0003] In the existing production, hard threads and twisted threads may be produced in the raw strips and cloth surface proofing. In addition, the current cotton feeding mechanism does not effectively remove cotton roll impurities mixed in the fibers, which can easily damage the needle clothing and affect the actual quality.

[0027] like Figure 1-5As shown, the cotton feeding mechanism of the cotton carding machine of the utility model comprises a cotton feeding plate 2 arranged on a machine frame 1, a cotton feeding roller 3 and a licker-in roller 4 constituting a cotton feeding channel are arranged on one end of the cotton feeding plate 2, a small leak bottom 5 is arranged on the right side of the lower end of the licker-in roller 4, and further comprises:

[0028] The carding mechanism 6 comprises a pre-carding plate 61 arranged on the left side below the licker-in roller 4, and a second dust removal knife 62 arranged on the pre-carding plate 61 near the cotton feeding plate 2;

[0029] A first dust removal blade 7 is provided on the machine frame 1 and is used for pre-removing hard threads and parallel threads in the cotton roll entering the cotton feeding channel;

[0030] A gap adjustment mechanism 8 is provided on one end of the small drain bottom 5 close to the pre-combing plate 61, and is used to adjust the gap between the second dust removal knife 62 and the small drain bottom 5;

[0031] The impurity cleaning mechanism 9 includes a support ring 91 arranged at one end of the licker-in roller 4, and a straight plate 92 arranged on the top of the support ring 91 and covering the combing needles and beaters on the licker-in roller 4, which is used to clean the cotton roll impurities adhered to the combing needles and beaters on the licker-in roller 4. With this design, the first dust removal knife 7 is bolted to the machine frame 1, and the first dust removal knife 7 is 10mm higher than the surface of the machine frame 1. The 90° large angle design can pre-clean the hard silk and the double silk in the cotton roll entering the cotton feeding channel, ensuring the quality of the cotton products produced in the later processing;

[0032] Through the gap adjustment mechanism 8 installed on the small drain bottom 5 near one end of the pre-combing plate 61, the length of the pre-combing plate 61 and the cotton supporting plate of the small drain bottom 5 can be changed, and the length can be extended to 25mm, so that the gap between the pre-combing plate 61 and the small drain bottom 5 is adjusted to 5mm, reducing the amount of cotton drop;

[0033] By means of a support ring 91 rotatably connected to one end of the licker-in roller 4 and a straight plate 92 integrally formed on the top of the support ring 91, cotton roll impurities adhering to the beaters of the combing needles on the licker-in roller 4 can be removed, thereby reducing the influence of cotton roll impurities on the operation of the carding machine and ensuring efficient operation of the carding machine.

[0034] In one embodiment, the second dust removal blade 62 is provided with an arc-shaped cotton supporting plate 621 for blocking the debris falling area between the pre-combing plate 61 and the first dust removal blade 7. In this design, by connecting the arc-shaped cotton supporting plate 621 to the second dust removal blade 62 in a manner including but not limited to bolt fixing, the debris falling area between the pre-combing plate 61 and the first dust removal blade 7 can be effectively blocked to ensure that the effective spinnable fibers are not lost.

[0035] In one embodiment, the gap adjustment mechanism 8 includes a support seat 81 arranged on the bottom surface of one end of the small leak bottom 5 close to the pre-combing plate 61, and an extended cotton supporting plate 82 rotatably arranged at the end of the small leak bottom 5. A telescopic cylinder 83 is arranged in the area between the support seat 81 and the extended cotton supporting plate 82, and symmetrical arc-shaped support springs 84 are respectively arranged in front and behind the telescopic cylinder 83 and are used to pull the support seat 81 and the extended cotton supporting plate 82. Such a design uses a telescopic cylinder 83 rotatably connected to a support seat 81 welded on the bottom surface of one end of the small leak bottom 5, and an extended cotton supporting plate 82 rotatably connected to the movable end of the telescopic cylinder 83, and the end of the extended cotton supporting plate 82 close to the small leak bottom 5 is connected by a rotating shaft. By lifting and lowering the telescopic cylinder 83, the angle of the extended cotton supporting plate 82 relative to the small leak bottom 5 can be adjusted, so as to achieve the effect of adjusting the size of the gap in the impurity dropping area reserved between the pre-combing plate 61 and the small leak bottom 5, so that the gap between the pre-combing plate 61 and the small leak bottom 5 is adjusted to 5 mm, thereby reducing the amount of cotton dropped.

[0036] In one embodiment, the impurity cleaning mechanism 9 further comprises a plurality of cleaning blocks 93 evenly arranged at the lower end of the straight plate 92, and a movable opening 94 is arranged between two adjacent cleaning blocks 93 to match the combing needles and beaters on the licker-in roller 4. In this design, the plurality of cleaning blocks 93 are welded at the lower end of the straight plate 92 and the movable openings 94 are spaced apart, and the spaced movable openings 94 can match the design of the combing needles and beaters on the licker-in roller 4, and can be closely attached to the outer surface of the combing needles and beaters on the licker-in roller 4. In the cotton combing operation stage, the cotton impurities adhering to the outer surface of the combing needles and beaters on the licker-in roller 4 are removed by the rotation of the licker-in roller 4.

[0037] In one embodiment, the two opposite end faces of the cleaning block 93 are provided with impurity inlets 95 that are connected inside and outside, and a connected air source channel 96 is provided inside the impurity inlet 95 and in the internal area formed by the support ring 91 and the straight plate 92. In this design, through the impurity inlets 95 opened by turning on the opposite end faces of the cleaning block 93, and the air source channel 96 designed to be connected with the impurity inlet 95, an air flow passage can be formed in the internal area formed by the support ring 91 and the straight plate 92, so that the impurities under cleaning are sucked in, thereby reducing the influence of cotton lap impurities on the operation of the carding machine.

[0038] In one embodiment, an air source connector 911 is provided on the support ring 91. With this design, an external air pump can be used to form a negative pressure environment through the air source connector 911 spirally connected outside the support ring 91, so as to achieve the effect of negative pressure suction of cotton roll impurities.

[0039] It should be noted that the outside of the air source connector 911 is connected to an air pump for exhausting air, and a collection box for collecting cotton roll impurities is connected to the air inlet end of the air pump.

[0040] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
