Description

Technical Field

[0001] The utility model relates to the field of drawing frame equipment, in particular to a double-sealed bell mouth device of a drawing frame. Background Art

[0002] The drawing frame is a textile machine that processes several carded or combed fiber strips into fiber strips with certain leather requirements. The bell mouth is one of the important components of the drawing frame. The existing bell mouth is sealed by a single sealing ring, which is prone to air leakage in the studio.

[0003] According to the patent document with the existing publication number CN206970782U, a bell mouth for a drawing frame is disclosed, which includes a bell mouth body, and the bell mouth body is a hollow conical structure. The bell mouth body includes a first bell mouth body and a second bell mouth body. The outer side of the second bell mouth body is provided with a fixing ear, and the fixing ear is provided with a magnet and a mounting hole from the inside to the outside. When in use, this technical solution increases the stability of the connection between the bell mouth and the base through the attraction between the magnet on the fixing ear and the base, prevents the bell mouth from shaking up and down with the impact force of the fiber strip, and enhances the stability of the automatic leveling detection device of the drawing frame. With respect to the above technical solution, although this solution achieves stability, it cannot be sealed and limited during use, which is inconvenient during use. Utility Model Content

[0006] Furthermore, air flow holes are provided on both sides of the bell mouth, and a connecting hole is provided between one ends of the air flow holes.

[0007] Furthermore, the connection hole is provided inside the bell mouth, and a slot is provided at one end of the bell mouth.

[0008] Furthermore, the connecting hole is connected to the slot, and a tapered opening is formed at one end of the connecting hole, and the tapered opening is distributed inside the bell mouth.

[0009] Furthermore, a limiting ring is fixed on the inner wall of the mounting hole, and the limiting ring cooperates with the sealing ring.

[0010] Furthermore, a pneumatic joint is fixedly installed on the bottom of the shelf, and the pneumatic joint cooperates with the air flow hole.

[0012] 1. A double-sealed bell mouth device for a drawing frame. When in use, the sealing ring is double-installed inside the bell mouth. The double layers of the sealing ring cooperate with the installation hole to avoid air leakage, thereby improving the success rate of automatic spinning of the sliver.

[0013] 2. A double-sealed bell mouth device of a drawing frame, wherein a limiting ring is fixed inside the mounting hole, the sealing ring cooperates with the limiting ring under extrusion, and the limiting ring cooperates with the bell mouth to seal and fix again.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figures 1 to 4The utility model provides a technical solution: a double-sealed bell-mouth device of a drawing frame, comprising a shelf 1, a mounting hole 3 is opened on the shelf 1, a bell-mouth 4 is movably installed inside the mounting hole 3, a limiting groove 5 is opened on the bell-mouth 4, a limiting block is fixed inside the mounting hole 3, the limiting block cooperates with the limiting groove 5, a fixing groove 6 is opened on the bell-mouth 4, a sealing ring 7 is fixedly installed inside the fixing groove 6, a mounting seat 2 is fixedly installed on the side of the shelf 1, a fixing hole is opened on the mounting seat 2, air flow holes 8 are opened on both sides of the bell-mouth 4, a connecting hole 11 is opened between one end of the air flow hole 8, and the air flow hole 8 cooperates with the pneumatic joint 12 to introduce gas to promote the movement of the cotton strip.

[0021] In this embodiment, the connecting hole 11 is opened inside the bell mouth 4, and a slot 9 is opened at one end of the bell mouth 4. The connecting hole 11 is connected to the slot 9. A conical mouth 10 is opened at one end of the connecting hole 11, and the conical mouth 10 is distributed inside the bell mouth 4. A limiting ring 13 is fixed on the inner wall of the mounting hole 3, and the limiting ring 13 cooperates with the sealing ring 7. A pneumatic joint 12 is fixedly installed on the bottom of the shelf 1, and the pneumatic joint 12 cooperates with the air flow hole 8. The limiting ring 13 limits the sealing ring 7 to avoid the influence caused by the bell mouth 4 shaking up and down inside the mounting hole 3.

[0022] When in use, the device cooperates with the limiting groove 5 on the side of the bell mouth 4 and the limiting block raised in the mounting hole 3 to achieve positioning for installation. After the bell mouth 4 is installed in the mounting hole 3, it needs to be pressed downward. The sealing ring 7 squeezes the limiting ring 13 under pressing, and the limiting ring 13 is deformed after being squeezed. After deformation, the sealing ring 7 passes through the limiting ring 13, and the limiting ring 13 contacts the outer wall of the bell mouth 4 for re-sealing. When in use, the sealing ring 7 is squeezed and cooperates with the limiting ring 13, and the limiting ring 13 cooperates with the bell mouth 4 to seal and fix again. In addition, the limiting ring 13 limits the sealing ring 7 to avoid the influence caused by the up and down shaking of the bell mouth 4 in the mounting hole 3. One end of the sliver is installed in the connecting hole 11 through the tapered mouth 10, and the pneumatic joint 12 blows gas into the gas. The gas flows in the air flow hole 8, and the flow drives one end of the sliver to be exposed from one end of the connecting hole 11, thereby completing automatic head production.
