In the description of the present application, the meaning of "a plurality of", "several" is two or more, unless otherwise explicitly specified.

[0026] Please refer to Figures 1 to 6The utility model provides a circulating cotton guiding mechanism, which comprises a first conveying belt 10 and a second conveying belt 20 arranged in layers, wherein the belt surface of the first conveying belt 10 facing the second conveying belt 20 forms a first clamping surface 101, the belt surface of the second conveying belt 20 facing the first conveying belt 10 forms a second clamping surface 201, and a cotton guiding channel suitable for clamping and conveying the cotton sliver is formed between the second clamping surface 201 and the first clamping surface 101; one end of the cotton guiding channel is close to a collection roller 50 to form an inlet 30, and the other end is close to the inlet end of a drafting mechanism 60 to form an outlet 40; wherein the inlet 30 is used for guiding the cotton sliver stripped from the collection roller 50 into the cotton guiding channel, and the outlet 40 is used for feeding the cotton sliver into the drafting mechanism 60.

[0027] It should be noted that the cotton sample is wound on the collection roller 50 in the form of a silk bundle after being pulled through the drafting mechanism 60, and the cotton sliver is cut or broken along the radial direction of the collection roller 50 after being completely wound on the collection roller 50 to form a state similar to a spool, and then the cotton sliver is stripped from the collection roller 50. Specifically, the cut or broken cotton sliver is stripped from the collection roller 50 and completely enters the cotton guiding channel due to the inlet 30 entering the cotton guiding channel, the rotation of the collection roller 50, and the operation of the first conveying belt 10 and the second conveying belt 20; in the cotton guiding channel, the first clamping surface 101 and the second clamping surface 201 form a clamping force on the cotton sliver, so that the cotton sliver reaches the outlet 40 following the operation of the first conveying belt 10 and the second conveying belt 20, and is finally continuously discharged from the outlet 40 and fed into the inlet end of the drafting mechanism 60; the drafting mechanism 60 completes drafting again and repeats the above process until the final cotton sliver sample is obtained after completing the drafting process multiple times (usually six times) according to the sample preparation standard.

[0028] Compared with the prior art, the circulating cotton guiding mechanism provided in the embodiment forms a cotton guiding channel by using the first clamping surface 101 of the first conveying belt 10 and the clamping surface of the second conveying belt 20, so that the cotton sliver stripped from the collection roller 50 enters the cotton guiding channel through the inlet 30, and then is fed into the drafting mechanism 60 through the outlet 40 under the cooperation of the first clamping surface 101 and the second clamping surface 201, thereby realizing the automatic transfer of the cotton sliver from the collection roller 50 to the drafting mechanism 60, and the transfer process does not require manual operation, so that the personnel occupation can be reduced.

[0029] In some embodiments, referring to Figures 2 to 4, the first conveyor belt 10 has a feeding belt section 102, which extends from the discharge port 40 to the feeding end of the drafting mechanism 60, and is used to feed the sliver discharged from the discharge port 40 into the drafting mechanism 60. If the sliver discharged from the discharge port 40 is directly fed into the drafting mechanism 60, the conveying speed of the first conveyor belt 10 and the second conveyor belt 20 needs to be completely matched with the feeding speed of the drafting mechanism 60, otherwise, the sliver is prone to be blocked between the discharge port 40 and the drafting mechanism 60. In this way, a part of the belt surface of the first conveyor belt 10 is used as the feeding belt section 102 to receive the sliver discharged from the discharge port 40, and the sliver is continuously pushed into the drafting mechanism 60 by the operation of the first conveyor belt 10. Since the sliver is not clamped on the feeding belt section 102, the sliver can slip on the feeding belt section 102, thereby avoiding the blocking of the feeding end of the drafting mechanism 60.

[0030] As a specific embodiment of the first conveyor belt 10, please refer to Figure 3 , the first conveyor belt 10 includes a first rotating roller 11, a second rotating roller 12, a third rotating roller 13, and a first guide roller set. The first rotating roller 11 is arranged close to the feeding end of the drafting mechanism 60. The second rotating roller 12 is arranged close to the collecting roller 50 and forms the discharge port 40 with the second conveyor belt 20. The third rotating roller 13 is arranged above the side of the first rotating roller 11 away from the second rotating roller 12 and forms the discharge port 40 with the second conveyor belt 20. The belt surface of the first conveyor belt 10 between the first rotating roller 11 and the second rotating roller 12 forms the feeding belt section 102.

[0031] The end of the sliver peeled off from the collecting roller 50 falls between the second rotating roller 12 and the second conveyor belt 20, and enters the guide channel by the rotation of the second rotating roller 12. In the guide channel, the part of the belt surface of the first conveyor belt 10 around the first guide roller set is used as the first clamping surface 101 to clamp the sliver together with the second clamping surface 201, so that the sliver moves towards the discharge port 40 following the operation of the first conveyor belt 10 and the second conveyor belt 20, and then falls into the feeding belt section 102 from the third rotating roller 13 and the second conveyor belt 20, and finally is fed into the drafting mechanism 60 by the first rotating roller 11. The structure is simple and compact, and the operation is stable and reliable.

[0032] In some possible implementation manners, please refer to Figure 3The first guide roller set comprises a fourth roller 14, a fifth roller 15 and a sixth roller 16. The fourth roller 14 is located below the first roller 11, the fifth roller 15 is located below the fourth roller 14, and the sixth roller 16 is located below the second roller 12. The belt surface of the first conveying belt 10 passes the first roller 11, the fourth roller 14, the second roller 12, the sixth roller 16, the fifth roller 15 and the third roller 13 in sequence and returns to the first roller 11. The belt surface of the first conveying belt 10 between the second roller 12 and the sixth roller 16, between the sixth roller 16 and the fifth roller 15 and between the fifth roller 15 and the third roller 13 forms the first clamping surface 101. The fourth roller 14 can guide the belt surface of the first conveying belt 10 to bend, so that the belt surface of the first conveying belt 10 can pass the drafting mechanism 60 and the collecting roller 50, avoiding running interference. On this basis, the fifth roller 15 and the sixth roller 16 can guide the belt surface of the first conveying belt 10 to bend and change direction on the lower side of the fourth roller 14 and form the first clamping surface 101, avoiding the upper and lower belt surfaces of the first conveying belt 10 from rubbing against each other.

[0033] Optionally, as shown in Figure 2 and Figure 3 , the first guide roller set of the embodiment further comprises a seventh roller 17 located between the second roller 12 and the sixth roller 16 for supporting the belt surface of the first conveying belt 10 between the fourth roller 14 and the second roller 12 to form an avoiding space for accommodating the drafting mechanism 60 and the collecting roller 50. The first roller 11 can make the upper belt surface of the first conveying belt 10 form an avoiding space with an open top, so as to ensure that the first conveying belt 10 can pass below the drafting mechanism 60 and the collecting roller 50, avoiding running interference.

[0034] It should be noted that, as shown in Figure 1 and Figure 5 , the first conveying belt 10 comprises a first driving member 18 arranged on the frame, and the output end of the first driving member 18 is in transmission connection with the fourth roller 14. The first driving member 18 can be a servo motor or a stepping motor. Since the belt surface of the first conveying belt 10 has a large wrap angle on the fourth roller 14, the first driving member 18 can drive the fourth roller 14 to rotate, thereby driving the first conveying belt 10 to run stably. The remaining rollers only need to be driven to rotate passively to guide the belt surface of the first conveying belt 10 to bend and change direction, so the structure is simple and compact.

[0035] For example, as shown in Figure 5The output end of the first driving member 18 is sleeved with a first driving wheel 181, the roller shaft of the fourth rotating roller 14 is sleeved with a first driven wheel 182, and the first driven wheel 182 and the first driving wheel 181 are connected through a first ring belt 183. The first driving wheel 181 and the first driven wheel 182 can be synchronous wheels, and the first ring belt can be a synchronous belt, so as to ensure the stability of the torque transmission from the first driving member 18 to the fourth rotating roller 14, thereby improving the operation stability of the first conveying belt 10.

[0036] As a specific embodiment of the second conveying belt 20, please refer to Figures 2 to 4 The second conveying belt 20 comprises an eighth rotating roller 21, a ninth rotating roller 22, a tenth rotating roller 23, an eleventh rotating roller 24 and a twelfth rotating roller 25. The eighth rotating roller 21 is located above the third rotating roller 13 and forms the discharge port 40 with the third rotating roller 13. The ninth rotating roller 22 is located above the second rotating roller 12 and forms the feeding port 30 with the second rotating roller 12. The belt surface of the second conveying belt 20 passes the eighth rotating roller 21, the third rotating roller 13, the fifth rotating roller 15, the sixth rotating roller 16, the ninth rotating roller 22, the tenth rotating roller 23, the eleventh rotating roller 24 and the twelfth rotating roller 25 in turn and returns to the eighth rotating roller 21. The belt surface of the second conveying belt 20 between the eighth rotating roller 21 and the third rotating roller 13, between the third rotating roller 13 and the fifth rotating roller 15, between the fifth rotating roller 15 and the sixth rotating roller 16 and between the sixth rotating roller 16 and the ninth rotating roller 22 forms the second clamping surface 201.

[0037] The eighth rotating roller 21 and the third rotating roller 13 are arranged above and below to form the discharge port 40 facing the drafting mechanism 60, and the ninth rotating roller 22 and the second rotating roller 12 are arranged above and below to form the feeding port 30 for conveniently receiving the cotton sliver stripped from the collecting roller 50. On this basis, the second conveying belt 20 and the first conveying belt 10 share the third rotating roller 13, the fifth rotating roller 15 and the sixth rotating roller 16, thereby forming the second clamping surface 201 which can completely match the first clamping surface 101. This not only helps to improve the compactness of the structure, but also improves the clamping and conveying stability of the first clamping surface 101 and the second clamping surface 201 on the cotton sliver. The tenth rotating roller 23, the eleventh rotating roller 24 and the twelfth rotating roller 25 can guide the lower belt surface of the second conveying belt 20 to be spaced from the second clamping surface 201, thereby avoiding the frictional interference between the upper and lower belt surfaces of the second conveying belt 20.

[0038] It should be noted that please refer to Figure 1 and Figure 6The second conveying belt 20 comprises a second driving element 26 arranged on the frame, an output end of the second driving element 26 is sleeved with a second driving wheel 261, a roller shaft of the tenth roller 23 is sleeved with a second driven wheel 262, and the second driven wheel 262 and the second driving wheel 261 are connected through a second ring belt 263. The second driving element 26 can be a servo motor or a synchronous motor, the second driving wheel 261 and the second driven wheel 262 can be synchronous wheels, and the second ring belt 263 can be a synchronous belt. Since the belt surface of the second conveying belt 20 has a large wrap angle on the tenth roller 23, the second driving element 26 transmits torque to the tenth roller 23, so that the tenth roller 23 is used as a driving roller and the other rollers are used as driven rollers, thereby realizing stable operation of the second conveying belt 20, and the driving mode is simple and compact, and the operation is stable and reliable.

[0039] Based on the same inventive concept, in combination with Figures 1 to 6 It should be understood that the application also provides a cotton sliver sampling machine comprising the above-mentioned circulating cotton guiding mechanism.

[0040] Compared with the prior art, the cotton sliver sampling machine provided by the utility model adopts the above-mentioned circulating cotton guiding mechanism, and the first conveying belt 10 and the second conveying belt 20 can cooperate to automatically transfer and feed the cotton sliver stripped from the collection roller 50 to the drafting mechanism 60, so that the automation of the whole sampling process is realized, and the personnel occupation is reduced.

[0041] The above only describes preferred embodiments of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
