Cotton web bundling mechanism of intelligent comber

[0020] Embodiment: A cotton web bundling mechanism of an intelligent combing machine, including first and second pressure rollers 4, 5, a driving device, a gathering pipe 1, a conveying pipe 2, and a gathering horn positioned on the support 8 of the intelligent combing machine Port 3, the first and second pressure rollers 4, 5 mesh with each other, the driving device drives the first pressure roller to rotate, the inlet of the gathering tube 1 is just behind the drafting output roller of the intelligent combing machine, the inlet of the conveying tube 2 and the gathering tube 1 The outlet is fixed and connected, and the cluster horn 3 is fixedly installed on the support 8 of the smart comber. The inlet of the cluster horn 3 can be communicated with the outlet of the conveying pipe 2. The inner side of the cluster horn 3 is a horn hole 13 whose outlet diameter is smaller than the inlet diameter. , The first and second pressure rollers 4, 5 meshing points are directly opposite to the outlet of the cluster bell mouth 3, the cluster bell mouth 3 is located on the side wall of the outlet end formed with a flat groove 12, the first and second pressure rollers 4, 5 mutually The meshing side is just inserted into the flat groove 12, and the meshing point is just inside the flat groove 12. When working, the first and second pressure rollers 4 and 5 are driven by the driving device to engage and drive to realize the transmission of the sliver. The cotton net output by the mechanism is conveyed to the cluster bell mouth 3 through the gathering pipe 1 and the conveying pipe 2. The inner hole of the gathering bell mouth 3 adopts the horn hole 13 to facilitate the gathering and guiding of the sliver, and the outlet diameter can be changed according to the thickness of the sliver. Different values, the value range is 4-7mm, the first and second pressure rollers 4 and 5 with the same tooth profile in the flat groove 12 on the upper side of the small outlet of the cluster bell mouth 3 mesh with each other, and the two walls of the flat groove 12 prevent the sliver Stretching outwards from the side, the sliver can be compressed across the entire cross-section, the sliver can be entangled for the second time, and the sliver can be transported. The web bundling mechanism of the smart comber significantly improves the gathering The cohesive force of the sliver makes the sliver not easy to loosen during the conveying process on the conveyor belt, and it is not easy to break the sliver at the turning point of the sliver, which is beneficial to the high-speed conveying of the sliver.

[0021] The width of the flat groove 12 is 7-11mm, and the width of the flat groove 12 on the upper side of the outlet of the clustered bell mouth 3 (3) is 1mm larger than the thickness of the teeth of the pressing wheel. When the first and second pressing rollers 4 and 5 are engaged, the wheel The teeth are centered in the flat groove 12 along the thickness direction, so that the first and second pressure rollers 4 and 5 with the same tooth profile mesh and drive each other, and the first and second pressure rollers 4 and 5 press uniformly indentation on the sliver, flat The two wall surfaces of the groove 12 prevent the sliver from extending from the side, thereby achieving compression of the sliver in the entire cross section, further improving the cohesive force of the sliver, and realizing the conveying of the sliver.

[0022] The two sides of the outlet end face of the clustering bell mouth 3 are respectively formed with arc surfaces matching the shape of the first and second pressing rollers 4 and 5.

[0023] The side wall of the cluster horn 3 is provided with at least two oblique eye perforations 10 evenly distributed along the circumferential direction of the side wall. The oblique eye perforations 10 are located on the end surface of the cluster horn 3, and the oblique eye perforations 10 The outlet end is just connected to the inside of the outlet of the clustered horn 3, the air inlet of the inclined eye hole 10 is connected to a positive pressure air source, and the inner wall of the horn is evenly distributed with two air eye holes inclined at a certain angle. The source provides positive air pressure to compact and guide the sliver, so that the sliver is held tightly.

[0024] The angle between the axis of the inclined eyelet and the axis of the cluster horn 3 on the horizontal plane is 8°-12°, and the axis of the inclined eyelet and the axis of the cluster horn 3 are on the vertical plane where the axis of the cluster horn 3 is located. The projection angle is 20°-24°, and the axis of the inclined eyelet is perpendicular to the end face of the inlet end of the cluster horn 3.

[0025] The outlet end of the delivery pipe 2 is overlapped with the inlet end face of the cluster bell mouth 3 through an inclined surface, which can facilitate the separation of the gathering pipe 1 and the delivery pipe 2 from the cluster bell mouth 3 and facilitate maintenance.

[0026] A fixed shaft 7 is fixed on the support 8 of the intelligent combing machine, a positioning hole perpendicular to the axial direction of the gather tube 1 is provided on the side wall of the gathering tube 1, and the fixed shaft 7 is movably inserted into the side wall of the gathering tube 1 in the circumferential direction In the positioning hole on the upper part, when the sliver accumulates in the gathering tube 1 or the conveying tube 2 to form a squeezing force, or when a failure occurs, the gathering tube 1 and the conveying tube 2 can be rotated to a certain position in the upper part, and the gathering horn The mouth 3 is detached, which is convenient for maintenance and disposal of accumulated sliver.

[0027] The intelligent combing machine support 8 is also provided with a sensor 6, which can sense that the rotation angle of the gathering pipe 1 and the conveying pipe 2 around the fixed axis 7 reaches the set value. The sensor 6 transmits a signal to the intelligent combing machine control unit. When the sliver is accumulated in the gathering pipe 1 or the conveying pipe 2, the gathering pipe 1 and the conveying pipe 2 will rotate around the fixed axis 7. The sensor 6 can detect whether the sliver is in the gathering pipe 1 or by detecting the deflection of the conveying pipe 2. The transportation pipe 2 accumulates and generates a stop signal through the control unit and triggers a fault signal at the same time.

[0028] A pressure rod 9 and a pressure driving device 11 are also provided. The pressure rod 9 is hinged on the support of the intelligent combing machine. The second pressure roller can be rotated at one end of the pressure rod 9, and the pressure driving device 11 can drive The pressure rod 9 rotates around the hinged shaft, and the intelligent comber control unit controls the pressure driving device 11 to move. The movement of the pressure rod 9 drives the second pressure roller to approach or leave the first pressure roller, which is convenient for maintenance.

[0029] The pressurizing driving device 11 is an air cylinder, the cylinder of the air cylinder is fixedly installed on the support 8 of the intelligent combing machine, and the piston rod of the air cylinder is hingedly connected with the other end of the pressurizing rod 9.
