Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] The present invention provides a device for preventing fiber entanglement, which is installed on a cotton feeding roller, the end of which is provided with an installation groove.

[0034] Please refer to Figure 1 and Figure 2 As shown, an embodiment of the anti-fiber entanglement device 10 of the present invention includes a tensioning assembly 100 and a blocking collar 200. The blocking collar 200 is sleeved on the tensioning assembly 100 and is spread open by the tensioning assembly 100. The tensioning assembly 100 is used to press the blocking collar 200 against the side wall of the mounting groove.

[0035] The aforementioned anti-fiber entanglement device 10 uses a tensioning assembly 100 to press a blocking collar 200 against the side wall of the mounting groove of the feed roller. The blocking collar 200 extends out of the mounting groove, blocking the gap between the feed roller and the mounting base, preventing fibers from falling into the gap and entangled on the mounting shaft at the end of the feed roller during the carding process. This ensures the normal operation of the feed roller, reduces equipment failure rate, improves production efficiency, and reduces production costs.

[0036] The blocking collar 200 is a deformable ring structure. Optionally, the blocking collar 200 can be, but is not limited to, felt. Felt is elastic, wear-resistant, flame-retardant, provides good sealing, and is low in cost.

[0037] like Figure 2 As shown, in one example, the tensioning assembly 100 includes a first tensioning member 110, a second tensioning member 120, a first adjusting member 130, and a second adjusting member 140.

[0038] The first tensioning component 110 includes a first support portion 111, a first mounting portion 112, and a first abutting portion 113. The first support portion 111 has an arc-shaped structure. The first mounting portion 112 and the first abutting portion 113 are respectively connected to both ends of the first support portion 111, and are located inside the circle of the first support portion 111. The first mounting portion 112 has a first threaded hole. The second tensioning component 120 includes a second support portion 121, a second mounting portion 122, and a second abutting portion 123. The second support portion 121 has an arc-shaped structure. The second mounting portion 122 and the second abutting portion 123 are respectively connected to both ends of the second support portion 121, and are located inside the circle of the second support portion 121. The second mounting portion 122 has a second threaded hole.

[0039] The first tensioning component 110 and the second tensioning component 120 are disposed opposite to each other. The first adjusting component 130 includes a first adjusting bolt 131, which engages with a first threaded hole and abuts against a second abutting portion 123. The second adjusting component 140 includes a second adjusting bolt 141, which engages with a second threaded hole and abuts against a first abutting portion 113. The first support portion 111 and the second support portion 121 cooperate to open the blocking collar 200.

[0040] In the above example, by screwing in the first adjusting bolt 131 and the second adjusting bolt 141, respectively, the second abutment portion 123 and the first abutment portion 113 are acted upon, increasing the distance between the first support portion 111 and the second support portion 121. This applies tension to the blocking collar 200, firmly pressing the blocking collar 200 against the side wall of the mounting groove. Through this structural design, the tensioning assembly 100 can firmly press the blocking collar 200 against the side wall of the mounting groove without the need for other supports, and the tension can be adjusted according to the size and material of the blocking collar 200.

[0041] In the specific example shown, the first support 111 is a semi-circular ring structure. The second support 121 is a semi-circular ring structure. The blocking collar 200 is a deformable circular ring structure.

[0042] In one example, the first mounting portion 112 includes a first mounting plate 1121 and a first mounting nut 1122, the first mounting nut 1122 being fixed to the first mounting plate 1121 and located between the second abutment portion 123 and the first mounting plate 1121.

[0043] In one example, the second mounting portion 122 includes a second mounting plate 1221 and a second mounting nut 1222, the second mounting nut 1222 being fixed to the second mounting plate 1221 and located between the first abutment portion 113 and the second mounting plate 1221.

[0044] In one example, the first abutment 113 is a plate-like structure, which is arranged parallel to the second mounting plate 1221.

[0045] In one example, the second abutment portion 123 is a plate-like structure, arranged parallel to the first mounting plate 1121.

[0046] In one example, the first support 111, the first mounting plate 1121, and the first abutment 113 are integrally formed, for example, by processing metal strips.

[0047] In one example, the second support 121, the second mounting plate 1221, and the second abutment 123 are integrally formed structures, for example, they can be formed by processing metal strips.

[0048] In one example, the first adjusting component 130 further includes a first locking nut 132, which engages with the first adjusting bolt 131 and is located on the side of the first mounting portion 112 away from the second abutment portion 123. By providing the first locking nut 132, the installation stability of the tensioning assembly 100 can be improved.

[0049] In one example, the second adjusting component 140 further includes a second locking nut 142, which engages with the second adjusting bolt 141 and is located on the side of the second mounting portion 122 away from the first abutment portion 113. By providing the second locking nut 142, the installation stability of the tensioning assembly 100 can be improved.

[0050] like Figure 2 As shown, in one example, a first protrusion 114 protruding toward the blocking collar 200 is formed on the outer arc surface of the first support portion 111.

[0051] In the above example, the first protrusion 114 can create resistance to the blocking collar 200, preventing the blocking collar 200 from sliding on the tensioning assembly 100.

[0052] The number of the first protrusion 114 is not limited to just one; there can be multiple protrusions, which can better resist the blocking ring 200, such as two or three.

[0053] In one example, the first protrusion 114 is formed by impacting the first support 111.

[0054] In one example, one end of the first protrusion 114 is a pointed tip, which can better resist the stop ring 200.

[0055] In one example, a second protrusion protruding toward the blocking collar 200 is formed on the outer arc surface of the second support 121.

[0056] In the example above, the second protrusion can create resistance to the blocking collar 200, preventing the blocking collar 200 from sliding on the tensioning assembly 100.

[0057] The number of second protrusions is not limited to one; there can be multiple protrusions to better resist the blocking ring 200, such as two or three.

[0058] In one example, the second protrusion is formed by impacting the second support 121.

[0059] In one example, one end of the second protrusion is a pointed tip, which can better resist the stop ring 200.

[0060] Further, please refer to Figure 3 As shown, the present invention also provides a cotton feeding roller 30, including a roller body 310, a mounting shaft 320, and a fiber entanglement prevention device 10 of any of the above examples. The roller body 310 has a mounting groove at its end, the mounting shaft 320 passes through the mounting groove and is connected to the end of the roller body 310, and the tensioning assembly 100 presses the blocking collar 200 against the side wall of the mounting groove, the blocking collar 200 extending out of the mounting groove.

[0061] The aforementioned feeding roller 30 presses the blocking collar 200 against the side wall of the mounting groove through the tensioning assembly 100. The blocking collar 200 extends out of the mounting groove, and the gap between the blocking roller body 310 and the mounting seat 40 prevents fibers from falling into the gap and getting tangled on the mounting shaft 320 during the carding process. This ensures the normal operation of the feeding roller 30, reduces equipment failure rate, improves production efficiency, and reduces production costs.

[0062] The fiber entanglement prevention device 10 can be provided at only one end of the roller body 310, or it can be provided at both ends of the roller body 310.

[0063] In one example, needles 312 are distributed on the roller surface of roller 310 for transferring cotton flow 50.

[0064] Furthermore, the present invention also provides a pneumatic cotton box, including a box body, a cotton feeding fan, and a cotton feeding roller 30 of any of the above examples, wherein the cotton feeding fan is connected to the box body, and the cotton feeding roller 30 is disposed in the box body.

[0065] The aforementioned pneumatic cotton box has the cotton feeding roller 30 of any of the above examples, and thus can achieve the corresponding technical effects.

[0066] Other structural features of the air pressure cotton box are existing technologies, and those skilled in the art can add corresponding structural features as needed.

[0067] Furthermore, the present invention also provides a carding machine, including a base and a feeding roller 30 of any of the above examples or the above-described pneumatic cotton box mounted on the base.

[0068] The carding machine described above has the feeding roller of any of the above examples or the pneumatic cotton box described above, and thus can achieve the corresponding technical effects.

[0069] Other structural features of the carding machine are existing technologies, and those skilled in the art can add corresponding structural features as needed.
