Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the embodiments will be briefly described below. It is obvious that the drawings in the following description are only some embodiments of the utility model, and that for a person skilled in the art, other drawings can be derived from them without inventive effort.

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings. The embodiments are not described in detail herein, but the embodiments of the present invention are not limited to the following embodiments.

Fig. 1 and 2 schematically show a schematic structural view and a top view of an embodiment of the guide wire device for an oven entrance according to the present invention, respectively. Fig. 3 schematically shows a structural diagram of another embodiment of the guide wire device for the entrance of the oven.

One embodiment of the present invention is shown in fig. 1 and 2. As shown in fig. 1, the guide wire device for oven entrance of the present invention comprises a support frame 1, a transverse guide wire 2 and two guide wire stoppers 3. The transverse wire guide 2 is transversely arranged on the support frame 1 and is used for supporting the tows to the surface of a roller at the inlet of the drying oven. The two guide wire limiting parts 3 are arranged on the same side of the transverse guide wire part 2, and the one side is any one side divided by taking a vertical plane where a central transverse axis of the transverse guide wire part 2 is located as a dividing plane, as shown in fig. 2, so that the direction and the width of the guide wire of the tows conveyed from the previous process are limited to be specified at the same side of the transverse guide wire part 2, and the phenomenon that the direction of the tows at the guide wire limiting parts 3 is possibly deformed due to the fact that the two guide wire limiting parts 3 are not located at the same side of the transverse guide wire part 2 is avoided. Meanwhile, the central axes of the two guide wire limit parts 3 are in a plane parallel to the vertical plane of the central axis of the transverse guide wire part 2, as shown in fig. 2. The two guide wire limiting parts 3 are obliquely arranged on the support frame 1 at two ends of the transverse guide wire part 2, and meanwhile, one ends of central shafts of the two guide wire limiting parts 3 are intersected or extension lines of one ends of the central shafts are intersected to be used for restraining tows and fixing the trend of the tows. In the embodiment shown in fig. 1, two guide wire stoppers 3 are located on the strand input side of the transverse guide wire 2 and are arranged on the support frame 1 at both ends of the transverse guide wire 2 in an inclined manner. As can be seen from fig. 1, the extension lines of the central axes of the two guide wire stoppers 3 finally intersect at a point (not shown). This embodiment makes it possible to fix the direction of the filament bundle before it enters the transverse filament guide 2 and to gather the filament bundle or to set the filament guide width to a certain desired width.

Meanwhile, the lateral wire guide 2 of the present embodiment can move in the longitudinal direction of the two wire stopper members 3. Because the two guide wire limiting parts 3 are obliquely arranged at the two ends of the transverse guide wire part 2, the intersecting position of the transverse guide wire part 2 and the two guide wire limiting parts 3 can be changed by moving the transverse guide wire part 2, and the length of the guide wire of the transverse guide wire part 2 between the two guide wire limiting parts 3 is further changed. That is, by moving the transverse wire guide 2 along the length direction of the wire guide limiting member 3, the width of the filament bundle passing through the transverse wire guide 2 can be adjusted, and the thickness and uniformity of the filament bundle can be further adjusted. For example, when the number of tows to be threaded is large, the transverse wire member 2 is moved to a position where the length between two points intersecting with the wire restricting member 3 is long, and the two positions where the transverse wire member 2 and the wire restricting member 3 intersect are fixed. Then starting to start the guide wire work, and adjusting the thickness of the filament bundle and keeping the filament bundle uniform through the specified longer guide wire width in the guide wire process. When the number of the tows passing through is small, the transverse wire member 2 is moved to a position where the length between two points intersecting with the wire restricting member 3 is short, and the two positions where the transverse wire member 2 and the wire restricting member 3 intersect are also fixed. And starting the guide wire to work, and adjusting the thickness of the filament bundle and keeping the filament bundle uniform by the specified short guide wire width in the guide wire process. Like this, adjust the width of horizontal seal wire spare 2 seal wire between two seal wire locating part 3 according to how much of silk bundle, can adjust thickness, the degree of consistency of silk bundle to guarantee the silk bundle quality.

As shown in fig. 1, the lateral wire guide member 2 and the two wire guide stoppers 3 are elongated members, and at least one surface of the lateral wire guide member 2, i.e., a surface in contact with the tow, is an arc-shaped surface that protrudes outward for supporting the tow while reducing damage to the tow. And two seal wire locating part 3 set up and relative surface relatively, and two seal wire locating part 3 are respectively also all outwards convex arcwall face towards the one side of silk bundle respectively promptly, are used for fixed silk bundle trend, prevent that silk bundle both ends landing from leading to the production accident to take place outside horizontal seal wire 2, also can reduce the damage to the silk bundle simultaneously.

The transverse wire members 2 and/or wire stops 3 are cylindrical elongated members or lamellar elongated members. That is, the lateral wire member 2 and the wire stopper 3 may be both cylindrical elongated members, both sheet-like elongated members, or a combination of cylindrical elongated members and sheet-like elongated members.

The transverse wire guide 2 and/or the wire guide stop 3 are made of glass material. That is, the transverse wire guide 2 and the wire guide stopper 3 may be both made of glass material, or may be a combination of glass material and other materials, such as polished stainless steel.

On the basis, the transverse guide wire part 2 and the guide wire limiting part 3 can both select a glass guide rod or a polished stainless steel guide rod, and a combination of the glass guide rod and the polished stainless steel guide rod. Or a selection of glass sheet elongated members or polished stainless steel sheet elongated members, and combinations thereof. Or a combination of a glass guide rod and a polished stainless steel thin slice thin piece and a combination of the glass thin slice thin piece and the polished stainless steel guide rod are selected. As shown in fig. 1, the transverse wire guiding member 2 and the wire guiding limiting member 3 are both glass guide rods, so that the wire guiding strands can be completely prevented from being damaged.

As shown in fig. 1, two guide wire position-limiting members 3 are obliquely placed on the supporting frame 1, and the distance between the upper ends of the two guide wire position-limiting members 3 is greater than the distance between the lower ends thereof, i.e. the guide wire position-limiting members are arranged in a V shape.

As shown in fig. 2, the outer surfaces of the two wire stoppers 3 are in contact with the outer surface thereof disposed on one side of the transverse wire member 2. In the present embodiment, the outer surfaces of the two guide wire stoppers 3 are in contact with the outer surface of the transverse guide wire member 2 on the tow input side. The arrangement mode can better play the roles of guiding wire limiting and adjusting the thickness and uniformity of the tows.

The transverse guide wire 2, the two guide wire limiting parts 3 and two connecting parts of the transverse guide wire 2 and the guide wire limiting parts 3 form a guide wire groove together. As shown in fig. 1, the guide groove is formed by three glass guide rods. The left and right opening edges of the yarn guide groove are perforated, namely, either one end or two ends of the two yarn guide limiting parts 3 are perforated, and the yarn guide limiting parts 3 are respectively fixed with the two longitudinal supporting legs 5 of the supporting frame 1 through the perforations by using binding bands or fixed by using hoops and the like. The transverse wire guide 2 is fixed on the transverse bracket 4 of the support frame 1 through a hoop, a bag clip and the like. Thus, the transverse guide wire part 2 and the guide wire limiting part 3 can be conveniently disassembled, assembled or replaced. The width of the guide groove is adjusted according to the guide width.

In the present embodiment, two guide wire stoppers 3 are provided on the support frame 1 in an inclined manner. Extension lines of one ends of central shafts of the two guide wire limiting parts 3 are intersected finally to form an included angle, the adjustable angle range of the included angle is 60-75 degrees, and the requirement of different tows on the width of the guide wire in the production process is met.

The transverse support 4 is used for supporting the transverse guide wire part 2, the support legs 5 are used for supporting the guide wire limiting parts 3, the two support legs 5 longitudinally extend to form an included angle of 60-75 degrees so as to support the two guide wire limiting parts 3 to be obliquely arranged, and researches show that the integrally formed support frame 1 designed by adopting the included angle of 60-75 degrees has the advantages of best stability, convenience in use and installation and quickness in maintenance and replacement. Because this horizontal support 4, two supporting legs 5 and connecting portion 6 all adopt slotted hole hollow out construction, 4 both ends of horizontal support all are fixed through bolt 7 with two supporting legs 5, make things convenient for the dismouting, and simultaneously, adopt slotted hole hollow out construction design can require the fixed position that removes bolt 7 according to the silk bundle trend and on-the-spot production, adjust horizontal support 4's height, inclination and supporting leg 5's inclination, thereby control and adjustment silk bundle trend and thickness degree of consistency, avoid damaging the silk bundle, and then improve the silk bundle quality, reduce the fault rate.

In the embodiment, the adjustment is performed by adopting the slotted hole hollow structure design, firstly, coarse adjustment is performed according to the running direction of the tows in production by matching the slotted hole hollow structure of the connecting part 6 with the bolt 7, namely, the fixed position of the connecting part 6 relative to the entrance of the oven is adjusted by contrasting the running direction and the deviation degree of the tows, the specific position of the bolt 7 on the slotted hole hollow structure of the connecting part 6 is selected to adjust the vertical height and the inclination angle of the tows, so as to realize primary correction and adjustment of the running direction of the tows, and the slotted hole hollow structure of the connecting part 6 can avoid the defect that the height of the support frame can not be adjusted vertically only by rotating the support frame when the support frame is fixed by the bolt in a conventional single drilling mode. And the oblong hole hollow structures of the transverse support 4 and the two supporting legs 5 are matched with the bolts 7, so that the trend of the tows can be further finely adjusted, namely the positions of the left end and the right end of the transverse support 4 at the oblong hole hollow structures of the two supporting legs 5 are adjusted, and the tows are fixed by the bolts 7, so that the upper height and the lower height of the tows and the inclination angle of the tows are further finely adjusted.

In addition, the connecting part 6 can fix the wire guiding device at the entrance of the oven through a bolt 7. The connecting part 6 of the embodiment is arranged at the bottom of the support frame 1, and the wire guiding device is fixed on a lower jaw cover at the entrance of the oven through a bolt 7, so that the wire guiding device is convenient to disassemble and assemble.
