DETAILED DESCRIPTION

The technical solution of the utility model is further described below through the accompanying drawings and embodiments.

Embodiment 1

The utility model discloses an automatic sliver cutting machine, as shown in FIG1 , comprising a sliver conveying component 1 and a sliver cutting component 2 arranged in parallel, one end of the sliver cutting component 2 is connected to a main driving component 3, and the sliver cutting component 2 is transmission-connected to the sliver conveying component 1.

The cotton strip breaking assembly 2 includes a third roller 21 and a fourth roller 22 which are arranged in parallel. The third roller 21 and the fourth roller 22 are connected via a speed change gear set 5. The third roller 21 is provided with a third guide wheel 23, and the fourth roller 22 is provided with a fourth guide cam 24. The third roller 21 rotates under the driving action of the main driving assembly 3, and the fourth roller 22 is connected to the third roller 21 through the speed change gear set 5, so that the third roller 21 and the fourth roller 22 rotate at three different speeds. The fourth guide cam 24 on the fourth roller 22 cooperates with the third guide wheel 23, and the two use the speed difference to tear the cotton strips.

The sliver conveying assembly 1 includes a first roller 11 and a second roller 12 which are arranged in parallel. The first roller 11 and the second roller 12 are connected by a constant-speed gear set 4. The first roller 11 is provided with a first guide wheel 13, and the second roller 12 is provided with a second guide wheel 14. The first guide wheel 13 and the second guide wheel 14 are used together for introducing and conveying the slivers. A third transmission wheel 6 is provided at one end of the second roller 12, and a fourth transmission wheel 7 is provided on the third roller 21. The third transmission wheel 6 is transmission-connected to the fourth transmission wheel 7.

In this embodiment, the transmission ratio of the third transmission wheel 6 to the fourth transmission wheel 7 is less than 1, so that the rotation speed of each roller in the sliver conveying assembly is less than the rotation speed of the third roller 21.

The main driving assembly includes a driving motor 31, a first transmission wheel 32 and a second transmission wheel 33. The first transmission wheel 32 is connected to the power output end of the driving motor 31, and the second transmission wheel 33 is sleeved on the third roller 21. The first transmission wheel 32 is connected to the second transmission wheel 33 in transmission connection.

The transmission ratio of the first transmission wheel 32 to the second transmission wheel 33 is greater than 1, which is used to achieve a deceleration function when the driving motor 31 drives the third roller 21 .

In this embodiment, each roller is supported by a roller bearing.

In some other embodiments, each guide bar wheel or guide bar cam is connected to the roller via a guide bar rod.

When the automatic sliver breaking machine disclosed in the present embodiment is working, the driving motor 31 drives the third roller 21 to rotate, and the third roller 21 drives the second roller 12 to rotate through the fourth transmission wheel 7 and the third transmission wheel 6. The second roller 12 drives the first roller 11 to rotate under the transmission action of the constant speed gear set 4, and then drives the first guide wheel 13 and the second guide wheel 14 to rotate to realize the introduction and transportation of the slivers. The third roller 21 drives the fourth roller 22 to rotate under the action of the speed change gear set 5. The third roller 21 and the fourth roller 22 rotate at different speeds, so that the fourth guide cam 24 and the third guide wheel 23 work together at different speeds, and the two use the speed difference to tear the slivers.

The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
