Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, in particular to a medical absorbent cotton carding machine with a cleaning mechanism and a cleaning method. Background Art

[0002] Medical absorbent cotton is the main sanitary material used in the medical industry for bandaging, protecting, and cleaning patients' wounds. It is also a medical device product that comes into direct contact with wounds. The production of medical absorbent cotton requires multiple processes such as combing cotton into rolls, degreasing, bleaching, washing, drying, and finishing.

[0003] The cotton carding machine is a common cotton carding equipment used in the production of medical absorbent cotton. Its working principle is to open, comb and remove impurities from the cotton fiber rolls sent from the previous process, so that all the curled cotton loops become basically straight single fibers. In the process, the broken seeds, impurities and short fibers left over from the cotton cleaning process are removed. In actual use, the cylinder is the main opening and combing component, and a large amount of dust and short fibers are easily adhered to its surface.

8. The medical absorbent cotton carding machine with a cleaning mechanism and the cleaning method according to claim 1, characterized in that: The top of the blank support plate (25) is fixedly connected to a porous support plate (26), the bottom of the blank support plate (25) is fixedly connected to an air suction port (27), one side of the bottom of the bottom support frame (1) is fixedly connected to a box body (29), an ash guide pipe (28) is fixedly connected between the top of the box body (29) and the bottom of the air suction port (27), an ash taking port (30) is provided at the front end of the box body (29), and the top of the box body (29) is threadedly connected to an internal thread. A dust bag (32) is movably connected to the bottom end of the internal threaded ring opening (31); a negative pressure fan (33) is installed on one side of the box body (29); four groups of weighing sensors (34) are installed on the bottom end of the box body (29); a weighing support plate (35) is arranged on the top end of the weighing sensors (34); a sealing door (36) is movably connected to one side of the front end of the bottom support frame (1); and a display screen (37) is fixedly connected to one side of the front end of the box body (29).

9. A medical absorbent cotton carding machine with a cleaning mechanism and a cleaning method according to claim 8, characterized in that: The porous support plate (26) is evenly provided with fine holes inside, the air suction port (27), the ash guide pipe (28), and the inside of the dust collection bag (32) are connected, and the weighing sensor (34) and the display screen (37) are electrically connected.

10. The medical absorbent cotton carding machine with a cleaning mechanism and the cleaning method according to claim 1, characterized in that: The steps for using this device are as follows: P1: The cotton yarn blanks that have been opened and rolled are guided by the feeding mechanism to the blank support plate (25), and the cotton feed rollers (23) roll to pull the cotton yarn blanks into the equipment, and three sets of pricking rollers (24) perform preliminary grasping and pricking on the cotton yarn blanks; P2: When the cotton yarn passes through the porous support plate (26) inside the blank support plate (25), the negative pressure fan (33) continuously exhausts air to the outside, and the sealing door (36) is in a closed state, so that a semi-vacuum state is formed inside the box body (29), and the external air rushes in along the porous support plate (26) and the air inlet (27), bringing the dust and grass seeds in the cotton yarn blank into the ash guide pipe (28) and collecting them in the dust bag (32). The weighing support plate (35) is supported at the bottom of the dust bag (32), and the weighing sensor (34) senses its weight in real time and feeds back the data on the display screen (37). When the staff finds that the weight of the dust bag (32) is too high, they open the sealing door (36), rotate the internal thread ring (31) to remove the dust bag (32), and clean the dust inside; P3: The cotton yarn that has been pierced is continuously rolled by the cylinder drum (14) and wrapped around the outside of the cylinder drum (14). The spikes on the surface of the movable cover plate group (19) and the spikes on the surface of the cylinder drum (14) interact with each other to further loosen the cotton yarn. P4: By controlling the second electric cylinder (20) to extend or retract, the height of the concave frame (21) can be controlled, that is, the pressing force of the soft cover plate pressing shaft (22) on the movable cover plate group (19) can be changed, thereby adjusting its tension; P5: The cotton yarn after being opened by grasping and pricking is pulled by the doffer (15) and discharged by the cotton discharge roller (16); P6: When the cylinder drum (14) needs to be cleaned, the first electric cylinder (12) extends upward to push the supporting trough body (2) upward as a whole, so that the brush roller (7) fits the bottom of the cylinder drum (14), the industrial vacuum cleaner is connected to the hot air blower access pipe (9), the servo motor (8) drives the brush roller (7) to rotate continuously, and the dust is continuously cleaned in coordination with the rotation of the cylinder drum (14). The industrial vacuum cleaner continuously sucks through the hot air blower access pipe (9) and the air guide groove (10) to discharge the dust, and then The metering pump is connected to the pump interface (6), the industrial vacuum cleaner is removed, and the hot air blower access pipe (9) is replaced with a hot air blower. The nozzle (5) at the top of the liquid dispensing pipe (4) sprays a fine mist of water toward the bottom of the cylinder drum (14), and the bottom of the cylinder drum (14) is cleaned in coordination with the rotation of the cylinder drum (14). Excess water stains drip into the water collection tank (3). The hot air blower continuously sprays hot air through the hot air blower access pipe (9) and the air guide groove (10) to dry the water stains on the surface of the cylinder drum (14).
