Description

Adhesive cotton suction flute pipe

Technical Field

The utility model relates to a spinning frame inhales cotton system, especially relates to inhale cotton flute pipe.

Background

The existing cotton-sucking flute mainly adopts three different processes and materials. One is that the air suction inlet and the cotton suction pipe are hot-drawn and formed by aluminum alloy, the two are formed by brazing, and then are subjected to oxidation treatment or electrophoresis treatment; the other is formed by brazing the aluminum-zinc sheet iron with the cotton suction pipe through folding and snapping the cotton suction pipe opening and painting the surface, and the process is out of date. The two production processes both comprise a welding process, the welding process has high requirements on the construction technical level of operators, the labor condition is poor, the defective rate is high, cotton wool is easy to hang at the welding seam to cause blockage, the surface treatment process is not beneficial to environmental protection, and the pipe wall is thin and easy to deform. Meanwhile, the manufacturing process of the two is complex, the labor intensity of personnel is high, the operating environment is poor, and the production cost is high. In addition, there is a technology of injection moulding integrated into one piece, for example chinese patent publication No. CN1657671a discloses a cotton suction flute pipe device of a spinning frame, it includes a cotton suction pipe and an air inlet, the cotton suction pipe and the air inlet are an integral piece formed by injection moulding of engineering plastics, and also for example chinese utility model patent publication No. CN210314644U applied before the applicant discloses a cotton suction flute pipe convenient for assembly, it includes a pipe body and a pipe joint, the pipe body is one of metal material or thermoplastic material, the pipe joint is another of thermoplastic material or metal material, the pipe body and the pipe joint are socket-spigot connected, the two ends of the pipe joint are provided with sealing bosses in interference fit with the pipe body. The cotton suction flute pipe does not hang cotton wool and cause blockage. But pipe shaft or coupling pressurized deformation make sealed boss and pipe shaft interference fit, and the operation is hard, and the sealed degree of cooperation of sealed boss and pipe shaft also can't guarantee.

SUMMERY OF THE UTILITY MODEL

The technical scheme of the utility model is that: the bonding type cotton sucking flute comprises a flute body and a pipe joint, wherein a window is formed in the flute body, a bonding mechanism is expanded at the bottom of the pipe joint, and the bonding mechanism is in bonding connection with the flute body on the periphery of the window.

In the above scheme the bonding mechanism is including covering the portion of covering that can hide the window, the portion of covering outwards expands to have the extension with the pipe shaft laminating, the extension bonds with the pipe shaft through gluing.

In the scheme, a glue injection port is formed in one end of the extending portion, an annular groove surrounding the window is formed in the inner surface of the extending portion, the glue injection port is located in the annular groove, and the extending portion in the annular groove is bonded with the pipe body through glue.

The improvement of the scheme is that ribs are arranged on the pipe body at two sides of the window along the axial direction of the pipe body, and clamping grooves connected with the ribs in a buckling mode are arranged on two side edges of the covering part and the extending part.

In the scheme, the section of the pipe body is peach-shaped, crescent-shaped or long waist-shaped.

The further improvement of the scheme is that the inner surface of the covering part is provided with a circle of limiting bosses positioned in the window.

The other end of the extension part is provided with a glue injection port positioned in the annular groove.

In the scheme, two ends of the pipe body are provided with the choke plugs.

The beneficial effects of the utility model are that adopt the injecting glue to come coupling joint and pipe shaft, the simple operation, the card that the cooperation of sealed reliable rib and draw-in groove made the coupling can be convenient is on the pipe shaft, and the design of ring channel can prevent that the injecting glue from spilling over.

Detailed Description

The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the accompanying drawings. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments of the ordinary skilled person in the art without creative work belong to the protection scope of the present invention.

Example 1: as shown in fig. 1-4, the bonded cotton-sucking flute pipe comprises a pipe body 2 and a pipe joint 1, wherein the pipe body is provided with a window 3, the other side opposite to the window is provided with a plurality of cotton-sucking ports, the bottom of the pipe joint is extended with a bonding mechanism along the axial direction of the pipe body, and the bonding mechanism is bonded with the pipe body around the window. The bonding mechanism can be an arc cover body, the bottom periphery of the arc cover body is bonded and connected with the periphery of the window through glue, and other possible shapes can be adopted as long as firm bonding matching can be realized through conformal matching with the periphery of the window. The section of the pipe body 2 is peach-shaped, crescent-shaped or long waist-shaped, or other possible shapes.

Example 2: the difference with embodiment 1 lies in that the bonding mechanism includes a covering portion 4 capable of covering the window, the covering portion is attached to the surface of the tube body, two ends of the covering portion extend outwards along the axial direction of the tube body to form an extending portion 5, the extending portion is bonded with the tube body through glue, or further, a glue injection port 6 is formed in one end of the extending portion, an annular groove 7 surrounding the window is formed in the inner surface of the extending portion, the annular groove has a certain distance from the window, the distance is a space for filling glue, the glue injection port is located in the annular groove, and the extending portion in the annular groove is bonded with the tube body through glue. Two ends of the pipe body are provided with choke plugs 11. The pipe body is made of aluminum, iron, copper or alloy, and the pipe joint is made of polyethylene, polypropylene, polystyrene, polyvinyl chloride, nylon or polyurethane. Enough clearance is left between the annular groove and the limiting boss, and enough clearance is left between the limiting boss and the window.

Example 3: as shown in fig. 5 to 8, the difference from embodiment 1 or 2 is that the tube body on both sides of the window is provided with ribs 8 along the axial direction thereof, that is, the tube body on both sides of the window has a left rib and a right rib, and both sides of the covering part and the extending part have locking grooves 9 for snap-fitting connection with the ribs, where the sides refer to the sides of the covering part and the extending part extending along the axial direction of the tube body, and the fitting of the pipe joint to the tube body is facilitated by the engagement of the ribs and the locking grooves.
