Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber spinning, in particular to an improved spinning head suction gun component. Background Art

[0002] When conventional yarn is textured, POY only passes through the inner tube of the hot box, so the head suction gun has only one positioning block. When producing island yarn, since the island yarn needs to be matched with high shrinkage FDY, the island POY enters the inner tube of the hot box, and the high shrinkage FDY goes through the outer tube of the hot box. Therefore, the head operation of island yarn is more complicated than that of conventional yarn. The suction gun must first be used to suck the yarn of the inner tube, then the suction gun is pulled out, and then the yarn of the outer tube is sucked. If there is no limit block on the outer tube, it is difficult to align the position, resulting in difficult operation and long operation time. Utility Model Content

[0003] The utility model aims to provide an improved threading suction gun assembly, which can facilitate the threading of wires at different positions by arranging two positioning blocks on the gun rod and cooperating with the suction gun seat, thereby reducing the threading difficulty and greatly reducing the threading time.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] An improved head suction gun assembly includes a suction gun and a plurality of linearly evenly distributed suction gun seats, the suction gun seats are fixed on a frame, the tail end of the suction gun is connected to a suction pipe, and one suction gun can cooperate with a plurality of suction gun seats to work; the suction gun includes a gun rod, and two parallel positioning blocks are fixed on the gun rod;

[0006] The suction gun seat is formed with two positioning slots arranged up and down.

[0007] By setting two positioning blocks, which are inserted into corresponding positioning slots, the suction gun can be positioned in two positions, which can facilitate the alignment of the suction gun with the outer wire tube or the inner wire tube, thereby facilitating the suction of the wire from the outer wire tube or the inner wire tube into the suction gun, thereby facilitating the threading work.

[0008] The utility model is further configured as follows: the gun rod comprises a long oblique tube arranged obliquely downward and a vertical short tube arranged at the lower end of the long oblique tube;

[0009] A suction head is sleeved on the vertical short tube, and a tapered hole which is larger at the top and smaller at the bottom is formed on the suction head, and the lower end of the tapered hole is communicated with the vertical short tube.

[0010] By setting the tapered hole, the aperture at the upper end of the tapered hole is larger, which can facilitate the entry of the wire; by setting the long inclined rod, it is convenient for workers to extend the suction head under the corresponding outer wire tube or inner wire tube without bending or squatting to operate.

[0011] The utility model is further configured as follows: an annular groove is formed on the middle outer wall of the vertical short tube;

[0012] The lower end of the suction head is formed with a sleeve hole that matches the clearance of the vertical short tube, and the side wall of the sleeve hole is formed with a radial hole, and a short pin is sleeved and fixed in the radial hole, and the inner end of the short pin extends into the annular groove. The suction head can rotate relative to the vertical short tube, so that the suction head can hit other parts to rotate, reducing the bumps and scratches of the suction head and other parts. The cooperation between the short pin and the annular groove can prevent the suction head from detaching from the vertical short tube.

[0013] The utility model is further configured as follows: the positioning block is in a "convex" shape, a gun rod mounting hole is formed on the positioning block, and a locking screw is screwed on the upper end of the positioning block;

[0014] The gun rod is formed with a countersunk surface, and the end of the locking screw inserted into the gun rod mounting hole is pressed against the countersunk surface. By the locking screw being pressed against the countersunk surface, relative rotation between the positioning block and the gun rod can be placed, thereby ensuring the relative position relationship between the positioning block and the suction head.

[0015] The utility model is further configured as follows: an opening is formed in the middle of the lower bottom surface of the positioning slot. By providing the opening, the suction gun can be easily separated from the suction gun seat or installed in the suction gun seat.

[0016] A limiting protrusion is formed at the inner end of the positioning slot, and the position of the positioning block can be further limited by the limiting protrusion, which makes it more convenient to align the suction head with the wire tube.

[0017] The outstanding effects of the utility model are:

[0018] Compared with the prior art, by arranging two positioning blocks on the gun rod and cooperating with the gun suction seat, the threading work of the wires at different positions can be facilitated, thereby reducing the threading difficulty and greatly reducing the threading time.

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] The following references Figures 1 to 3 The utility model is described as follows:

[0027] An improved head suction gun assembly includes a suction gun 10 and a plurality of linearly evenly distributed suction gun seats 20, the suction gun seats 20 are fixed on a frame, the tail end of the suction gun is connected to a suction pipe, and one suction gun can cooperate with a plurality of suction gun seats; the suction gun 10 includes a gun rod 101, and two parallel positioning blocks 102 are fixed on the gun rod 101;

[0028] The suction gun seat 20 is formed with two positioning slots 201 arranged up and down, and the middle part of the lower bottom surface of the positioning slot 201 is formed with an opening 202. By providing the opening, the suction gun can be easily separated from the suction gun seat or installed into the suction gun seat.

[0029] The inner end of the positioning slot 201 is formed with a limiting protrusion 203, and the position of the positioning block can be further limited by the limiting protrusion, so that the suction head and the wire tube are more easily aligned.

[0030] By setting two positioning blocks, which are inserted into corresponding positioning slots, the suction gun can be positioned in two positions, which can facilitate the alignment of the suction gun with the outer wire tube or the inner wire tube, thereby facilitating the suction of the wire from the outer wire tube or the inner wire tube into the suction gun, thereby facilitating the threading work.

[0031] The gun barrel 101 includes a long inclined tube 103 disposed obliquely downward and a vertical short tube 104 disposed at the lower end of the long inclined tube 103;

[0032] A suction head 105 is sleeved on the vertical short tube 104 . A tapered hole 106 which is larger at the top and smaller at the bottom is formed on the suction head 105 . The lower end of the tapered hole 106 is communicated with the vertical short tube 104 .

[0033] By setting the tapered hole, the aperture at the upper end of the tapered hole is larger, which can facilitate the entry of the wire; by setting the long inclined rod, it is convenient for workers to extend the suction head under the corresponding outer wire tube or inner wire tube without bending or squatting to operate.

[0034] An annular groove 107 is formed on the middle outer wall of the vertical short tube 104;

[0035] The lower end of the suction head 105 is formed with a sleeve hole 108 that is gap-matched with the vertical short tube 104, and a radial hole 109 is formed on the side wall of the sleeve hole 108. A short pin 110 is sleeved and fixed in the radial hole 109, and the inner end of the short pin 110 extends into the annular groove 107. The suction head can rotate relative to the vertical short tube, so that the suction head can hit other parts to rotate, reducing the bumps and scratches of the suction head and other parts. The cooperation between the short pin and the annular groove can prevent the suction head from detaching from the vertical short tube.

[0036] The positioning block 102 is in a "convex" shape, and a gun barrel mounting hole 111 is formed on the positioning block 102. A locking screw 112 is screwed to the upper end of the positioning block 102.

[0037] The gun barrel 101 is formed with a countersunk surface 113, and the end of the locking screw 112 inserted into the gun barrel mounting hole 111 is pressed against the countersunk surface 113. By pressing the locking screw against the countersunk surface, the positioning block and the gun barrel can be prevented from rotating relative to each other, thereby ensuring the relative position relationship between the positioning block and the suction head.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications of the above assumptions should also be regarded as the protection scope of the present invention.
