Detailed Description
The technical solution of the present invention will be described in detail with reference to the accompanying drawings.
The embodiment of the utility model provides a yarn end draw gear, as shown in figure 1, including body 1, body 1 is including the threading chamber 11 that runs through body 1. An air inlet 12 and an air outlet 13 are arranged on the body 1, the air inlet 12 is communicated with the air outlet 13, and the air outlet 12 is communicated with the threading cavity 11.
When the device is used, the body 1 of the yarn end traction device is positioned between a working unit of a bobbin winder and a cop, the bottom opening of the threading cavity 11 is opposite to the small-end pipe orifice of the cop 4, and the top opening of the threading cavity 11 is opposite to the yarn suction pipe orifice of the working unit of the bobbin winder. Air flow is introduced from the air inlet 12 through the air pipe 2, flows into the threading cavity 11 through the air outlet 13, drives the yarn end positioned at the bottom opening of the threading cavity 11 to move upwards from the threading cavity 11, and if the reserved length of the yarn end is short, the yarn end is separated from the cop under the action of the air flow, and finally extends out from the top opening of the threading cavity to reach the position of a yarn sucking pipe opening of a working unit of the bobbin winder.
In the yarn end traction device of the embodiment, the threading cavity 11 is used as a traction channel of the yarn end, and the air outlet 13 and the air inlet 12 which are communicated with the threading cavity 11 are used as power channels to provide power, so that the yarn end moves upwards and is separated from a loop in the threading cavity 11, and the yarn end is directionally and lengthily fed from a cop to the position of a yarn sucking opening of a working unit of a bobbin winder.
Preferably, the air outlet 13 is located on the lower inner wall of the threading cavity 11, and the air outlet direction of the air outlet 13 is inclined upwards. The air current blows in the threading cavity 11 from the lower part of the threading cavity 11 in an inclined mode upwards, and generates upward inclined thrust on the yarn end to push the yarn end to move upwards in the threading cavity 11, so that the yarn end can be effectively prevented from falling, and the knocking-over effect of the yarn end is improved.
Preferably, the body 1 further comprises an air duct, and the air inlet 12 is communicated with the air outlet 13 through the air duct. In view of reducing the volume of the body 1 and saving raw materials, the air inlet 12, the air outlet 13 and the ventilation duct are convenient to process on the side wall, and the lower part of the body 1 is provided with a boss, so that the side wall of the lower part of the threading cavity 11 is thicker than the side wall of the upper part. The air duct is arranged on the side wall of the lower portion of the threading cavity 11 and comprises a first channel 141 and a second channel 142, the air inlet 12 is connected with the first channel 141, the first channel 141 is connected with the second channel 142, the second channel 142 is connected with the air outlet 13, the first channel 141 is vertically distributed, and the second channel 142 is transversely distributed.
Preferably, the second channel 142 is inclined upwardly. The airflow is blown out from the second channel 142 which is inclined upwards through the air outlet 13, and the airflow is also inclined upwards to drive the yarn end to be upward, so that the knocking-over effect of the yarn end is improved.
Preferably, there are two air ducts, and the two air ducts are symmetrically arranged on two sides of the lower portion of the threading cavity 11. Two air ducts are respectively arranged on two sides of the lower portion of the threading cavity 11, air flow blows into the threading cavity 11 from two sides, and under the action of the two air flows, the yarn end is located in the middle of the threading cavity 11 and moves upwards, so that the moving and knocking-over effects cannot be influenced by touching the side wall of the threading cavity 11.
Preferably, the body 1 further comprises a ventilation cavity, and the air inlet 12 is communicated with the air outlet 13 through the ventilation cavity. After the air current lets in from air intake 12, collect the ventilation intracavity earlier, blow in threading chamber 11 through air outlet 13 again after reaching a certain amount, increase the air flow that blows in threading chamber 11 big, strengthen the pulling force for the yarn end moves up rapidly and knocks off the circle, further improves the success rate that the yarn end reaches the suction tube mouth.
Furthermore, the ventilation chamber is located threading chamber 11 lower part a week, and the bottom surface in ventilation chamber is the conical surface that the vertex of a cone is up, and air outlet 13 is located the top of conical surface. The air current that gathers in the ventilation chamber upwards reaches air outlet 13 along the conical surface from the bottom in ventilation chamber, and the slope is upwards blown in threading chamber 11, produces the ascending thrust of slope to the yarn end, promotes yarn end rebound in threading chamber 11, can prevent effectively that the yarn end from dropping.
Preferably, the bottom opening of threading cavity 11 is trumpet-shaped. The trumpet-shaped opening plays a good guiding role, and the yarn end can conveniently enter the threading cavity 11.
Preferably, the yarn end pulling device of the present embodiment further comprises a blowing member, and the blowing member is connected to the air inlet 12. The blowing piece can be connected with the air inlet 12 through an air pipe, provides air flow, enters the threading cavity 11 from the air inlet 12 and drives the yarn end to move upwards.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention.
