DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example: See Figures 1 to 6 According to an embodiment of the utility model, a technical solution is provided: a card clothing for a cotton carding machine cylinder, comprising a shaft column 1 and a needle body 2, the shaft column 1 is provided with a bearing part 3, and also comprises a base 4, on the top of which the needle body 2 is fixed, and the shaft column 1 is provided with a plurality of first slots 5 suitable for at least partial insertion of the base 4 at intervals along its length direction; a first limiting column 9, a second slot 6 suitable for the insertion of the first limiting column 9 is provided on the base 4, a third slot 7 is vertically provided at the bottom of the second slot 6, and the third slot 7 passes through the base 4 and is connected to the outside; and a second limiting column 10, which is arranged in the third slot 7, and the top of one end of the second limiting column 10 facing the second slot 6 is inclined, and a fourth slot 8 suitable for the insertion of the second limiting part is provided in the bearing part 3.

[0028] When the user needs to replace the needle body 2 of the carding machine cylinder needle clothing using the above-mentioned structure, the first limit column 9 on the base 4 is pulled out, and then the shaft column 1 is rotated, and the second limit column 10 is separated from the fourth slot 8 on the bearing part 3 by gravity, so that the base 4 and the bearing part 3 are in a non-fixed state, and then the base 4 is taken out to separate it from the first slot 5. At this time, a new needle body 2 fixed to the base 4 is taken out, and the new needle body 2 is placed into the first slot 5 through the base 4. The first limit column 9 is pressed against the inclined surface of the second limit column 10, and the second limit column 10 is pressed into the fourth slot 8, so that the bearing part 3 and the base 4 are in a relatively fixed state. At this point, the disassembly and replacement of the needle body 2 is completed, and the device is convenient for users to replace the damaged needle body 2.

[0029] In this embodiment, a first magnetic component 11 is fixed in the first slot 5, and the first magnetic component 11 is suitable for magnetically adsorbing the base 4; when the user puts the base 4 into the first slot 5, the magnetic component will magnetically adsorb the base 4 to make the base 4 more stable when in the first slot 5.

[0030] In this embodiment, a second magnetic component 12 is fixed in the base 4. The second magnetic component 12 is set away from the third slot 7 and is suitable for magnetically adsorbing the second limiting column 10. After the user pulls out the first limiting column 9, the second limiting column 10 will be magnetically adsorbed by the second magnetic component 12, so that the second limiting column 10 is separated from the fourth slot 8 on the bearing part 3, thereby improving the efficiency of the user pulling out the base 4.

[0031] In this embodiment, a pressing portion 13 is installed on one side of the top of the base 4, and a friction-increasing portion 14 protrudes from the pressing portion 13; when the user presses the base 4 into the first slot 5, the pressing portion 13 is pressed to press the base 4 into the first slot 5, and the friction-increasing portion 14 on the pressing portion 13 increases the friction force of the user's fingers on the base 4, so as to facilitate the user to press the base 4 into the first slot 5.

[0032] In this embodiment, two hinged seats 15 are spaced apart at the top of the first limit column 9, a locking rod 16 is hinged between the two hinged seats 15, a locking column 17 protrudes downward from the free end of the locking rod 16, and a locking hole 18 suitable for inserting the locking column 17 is opened on the base 4; when the user uses the first limit column 9 to press the second limit column 10 into the fourth slot 8, the locking rod 16 on the top of the first limit column 9 is swung to drive the locking column 17 to insert into the locking hole 18, so as to prevent the first limit column 9 from disengaging from the second slot 6 when the shaft column 1 rotates.

[0033] In this embodiment, the locking column 17 is constructed of rubber material; when the locking column 17 is inserted into the locking hole 18, the locking column 17 made of rubber material will increase the friction between the locking hole 18 and the locking column 17 to further prevent the locking column 17 from escaping from the locking hole 18 when the shaft column 1 rotates.

[0034] Working principle: when the user needs to replace the needle body 2, first pull out the first limiting column 9 on the base 4. After the user pulls out the first limiting column 9, the second limiting column 10 will be magnetically attracted by the second magnetic attraction part 12, and the second limiting column 10 will be separated from the fourth slot 8 on the bearing part 3, so that the base 4 and the bearing part 3 are in a non-fixed state, and then the base 4 is taken out to separate it from the first slot 5. At this time, take out a new needle body 2 fixed to the base 4, and put the new needle body 2 into the first slot 5 through the base 4. When the user presses the base 4 into the first slot 5, the pressing part 13 is pressed to press the base 4 into the first slot 5. The friction-increasing part 14 on the pressing part 13 will increase the friction force of the user's fingers on the base 4, so that the user can press the base 4 into the first slot 5. After the user puts the base 4 into the first slot 5 The magnetic attraction part will magnetically absorb the base 4 so that the base 4 will be more stable when it is in the first slot 5, and then press the first limit column 9 against the inclined surface of the second limit column 10, and press the second limit column 10 into the fourth slot 8, so that the bearing part 3 and the base 4 are in a relatively fixed state. When the user uses the first limit column 9 to press the second limit column 10 into the fourth slot 8, the locking rod 16 on the top of the first limit column 9 is swung to drive the locking column 17 to insert into the locking hole 18 to prevent the first limit column 9 from disengaging from the second slot 6 when the shaft column 1 rotates. The locking column 17 made of rubber material will increase the friction between the locking hole 18 and the locking column 17 to further prevent the locking column 17 from disengaging from the locking hole 18 when the shaft column 1 rotates. At this point, the disassembly and replacement of the needle body 2 is completed, and the device is convenient for users to replace damaged needle bodies 2.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
