Description of the Invention: [Technical Field] The present invention relates to a stretching unit for a knitting machine according to the preamble of the scope of the patent application. [Prior Art] In the past, various methods of manufacturing a needle directly from a staple fiber roving or roving have been proposed. Combining a substantially flawless fiber tampon with approximately parallel-arranged = woven knit fabric is very soft and comfortable to wear" and due to the intermediate stage of the traditional spinning (yarn formation, it is wound up to the station) ^ and possibly repeated winding) is omitted, and it is very economical to produce the knitted fabric. The flawless fiber tampon has a certain degree of longitudinal elasticity at the same time, because the direction of the yarn that guides the knitting machine is changed and the yarn is not passed through the US-A_3'877'254 To the knitting, the case of the intermediate knitting machine is taken as an example. The short fibers are arranged by a brush into a 圏, and a wheel with a squid is tested and then transferred to the short fiber. Circular knitting machine for cloth. The interlacing points in the grid give the knitted fabric the necessary strength. It also shows that the auxiliary line of the line can also be woven into it. , y-line In the second Γ 4 / () 79 () 68 proposed a circular knitting machine, the woven area of the woven area of the line of stretched refined yarn for the yarn. The draw frame 2 has one or more syringes, which have a double apron and a ring-type refining machine for the yarn of the outlet. The roving is drawn from a drum or _ 5 200932975 roving bobbin and supplied to a draw frame that stretches it to a predetermined extent. The drawn fiber tampon can be provided directly to the knitting needles located in the woven zone after the exit pressure profile. This configuration is particularly useful for circular knitting machines having a very straight pinch cylinder, for example, a long fiber can be processed thereon. For a large circular knitting machine with a larger size of the syringe, for example, 48 or 96 knitting zones can be set, which proposes to be used to deliver the skin 'μ' to the device σ and to the draw frame and the Between the weaving zones, for example, the twisting device comprises a pneumatically operated swirling nozzle, wherein the weaving is provided to the drawn fiber tampon. The temporary yarn thus formed has sufficient strength to be conveyed a long distance. The false twist is again released in the weaving zone, so that the fibers are substantially parallel to each other when they are combined by the knitting needle to form a knitted fabric. For space reasons, for example, the draw frame is distributed into three groups. Surrounding the circumference of the cylinder of the circular knitting machine. Each group of draw frames includes a plurality of draw frames in the same line and is co-driven for the drive elements of the draw frame. Including at least one continuous syringe. To avoid this, excessively sharp changes in the direction of passage of the fibers between the set of draw frames and their associated weaving zones, initiating a weaving zone at the syringe instead of a so-called dead zone or dead zone, Here (four) edit # looms There is an I weave or the area is not woven. Thus, on a large circular knitting machine formed by a known method, only about half of the weaving area is available. In this relationship, even in w〇004/079G68 It is explained that it is not the most important to directly weave the roving according to economic advantages. It is even suggested that, in another way, the size of the cylinder can be enlarged, so that the circumference of the cylinder can be provided with a plurality of usable knitting zones. 6 200932975 In fact, when the processed fiber tampon is stretched in the Sweat Machine, only a part of the woven area on the large circular knitting machine is ΛM ^ m 疋, which shows that the depth is == A serious technical disadvantage. Increasing the size of the syringe is a technical step backwards, and due to structural reasons and lack of openness, it is impossible under any circumstances. In addition, the Group B armored draw frame is A group means that it is very difficult to repair them. [Summary of the Invention]

A stretching unit for forming a fiber tampon of a (four) yarn is provided, and a circular knitting machine towel of a conventional knitting machine, a special cooker structure and size, is allowed to be used in all existing knitting zones. The stretching unit has a simple design, an economical structure and is particularly easy to repair. The term roving is hereinafter generally referred to as a spun yarn and a draw frame sliver having a flick and usually provided to a bobbin which is flawless and is provided in a drum. This work is carried out by a stretching unit of a knitting machine having the features described in the section of the patent application. Further modifications and/or other advantageous embodiments of the invention are within the scope of the appended claims. The present invention proposes a stretching unit for a knitting machine for forming a roving into a fiber tampon, which is characterized by having a double apron guided by a apron roller and a pair of outlet pressure rollers which can be driven by a motor. The pair of apron roller and outlet pressure roller pairs for the double apron respectively engage a driven lower barrel, the shaft of which is coupled to the base of the base of 200932975 and extends outward. The motor powers the lower syringe. In contrast to the cutting technique, (iv) is formed in a circular knitting machine, which has a common driving unit, and the lower assembly of 1 is made into an autonomous element. 2, etc., has its own drive elements and stretches the tensile early element to leave the six η piece.

Two electric motors are sufficient to operate the stretch unit. The driving of the lower inlet cylinder and the driving of the lower apron cylinder for the double belt are provided by the same electric motor. The electric motor is preferably a synchronous electric motor. It is known that a class 1 air motor is driven by a frequency converter and it can be produced economically. Operation by the frequency converter 'allows the electric motor to be completely synchronized in a separate stretching unit in a circular knitting machine having 48 turns or 96 weaving zones. In order to provide a precise conveying path for the roving supplied to the stretching unit, it is preferable that no wire guide is provided at the entrance of the stretching unit in the conveying direction of the roving. For space reasons, one stretching unit may be supplied to two weaves. Thus, two adjacent wire guides may be placed at the entrance of the stretching unit, each of which defines a conveying path for the roving. Preferably, each of the wire guides has a passage which tapers in the conveying direction. Thus, the supplied roving will experience a certain degree of pressure before being stretched. In particular, the fibers protruding toward the ends are again incorporated into the roving. In this way, the roving can be stretched more efficiently and the fibers in the air can be reduced. This may also be suitable for a separate wire guide 0 combining two or more adjacent channels. In order to replace the stretching unit as quickly as possible, the base has a quick de-tensioning device by which the base can be connected to the adjacent The weaving area is part of the structure of the knitting 9 200932975 machine. Thus, the time required for the knitting machine to stop the soil due to repair or maintenance is minimized. In order to make the stretching unit easier to install, especially on a conventionally sized circular knitting machine, it is advantageous if its height matches the length of the shaft of the lower cylinder. The height is preferably 50 mm to 1 inch. Between 〇匪. ❹ ❹ According to this month's knitting machine with a stretched single cymbal, all the woven fabrics can be involved in the weaving. The woven fiber made directly from the roving is drawn into a fiber tampon. The intermediate stage of the conventional spinning (formation of the yarn, which is wound onto the bobbin and possibly repeatedly wound) (4) is omitted. The knitted fabric formed here has sufficient strength and is very soft. The stretching unit according to the present invention can be used for a flat knitting machine as well as a circular knitting machine. However, it is particularly suitable for use in a circular knitting machine having 48 or 96 knitting zones. Compared with the drawing machine which combines the circular knitting machine and the former balance on the knitting machine, the simple structure of the stretching method according to the present invention can make all the knitting zones in the circular knitting machine used. In the further practical Φ 八龙 of the present invention, the knives are assigned to each of the individual stretched ridges: or more adjacent woven areas. This gives the stretching unit according to the invention. Two particularly compact circular knitting machines [Embodiment] The same elements are used for the sake of clarity, and the reference numerals in the drawings are shown in Fig. 1 as a circular knitting machine. Important component overview, 10 200932975 1 means 'its knitted fabric directly from roving. The circular needle (4) has a syringe 2, for example a movable setting 48 or a % knitting needle 3 on the cylinder, in particular a tongue type needle. The knitting needle 3 directly processes the draw tampon from a drum 5 or the roving from the roving of the roving bobbin, and places it on the bobbin of the circular knitting machine. The roving L is stretched in the stretching unit 6 and supplied to the knitting needle 3 directly or through an intermediate twisting device 4 to form the fiber tampon into a knitted fabric which is made from the roving L The stretched fiber tampon has a false twist. The stretching unit particularly includes a three-cylinder barrel in Fig. i and includes a crucible inlet waste rod 7, a double bead 8 guided by the apron and a pair of outlet pressure rollers 9. This or the same type of draw frame is generally used for ring spinning machines. The conveying direction of the roving L or the forming direction of the fiber tampon is indicated by an arrow T in Fig. 1 . The stretching unit 6 of -5 is a three-cylinder draw frame for stretching a so-called roving. A roving is a roving that already has a constant twist. Appropriately, the spun yarn wound on the roving bobbin can be easily placed on the bobbin, the bobbin of a loom (especially a circular knitting machine). The roving has a high height and allows a long distance to be transmitted. Since the roving yarn is stretched to the yarn of the desired fine f, the stalk must be loosened in the preliminary stretch zone of the draw frame when the stretch reaches a predetermined extent in the main stretch zone. open. As shown in the three-cylinder draw frame 6, the preliminary stretch zone is used for the apron roller of the double apron 8 from the pair of inlets. The preliminary stretching is formed by the different peripheral velocities of the pair of parents, and the peripheral speed is about 1.2 or 1.4. / To stretch the zone from the double skin® 8 to the pair of outlets > 1 force light 9. In the main stretch zone, the roving L is stretched by a factor of between 25 and 5 Torr. 200932975 ❹ ❹ As shown in Figures 2 to 5, the entire stretching unit 6 is located on a base 60. Each pair of rollers has upper pressure rollers 71, 81, 91 and lower syringes 72, 82, 92, respectively. The pair of inlet pressure rollers 7, the apron roller for the double apron 8, and the lower cylinders 72, 82 and 92 of the pair of outlet pressure rollers 9 are located on the shaft connected to one end of the base 6'''''''' The inlet pressure roller 71 and the other apron roller 81 have their bearings on the respective assembly discs 78 which are attached to a resilient clip 75 of the base 6''. The spring clip 75 extends between a support bearing 79 extending from the base 6〇 and a thrust point 77 provided on the assembly disk, and is tensioned by a clamping cam having a pivot on the base 60. . Thus, the upper inlet pressure roller 71 and the upper apron roller 81 are pressed against the lower inlet pressure cylinder 72 and the lower apron cylinder 82, respectively. This tension can be adjusted by the tightness projection 6. The upper outlet pressure roller 91 is located on a bracket 96 that is free to move about the base. The bracket 96 is tensioned by a steel plate magazine %, and its end is fixed to an assembly protrusion 95 of the base 6〇. The outlet: the force roller 91 is located only on the bracket 96 and can be easily moved against the tension of the leaf spring by raising the outlet force roller 91 from the lower outlet. The solid:::cylinder 72,82' 92 is driven by the electric motor 62, 63, and the electric "up to! wide and freely extend outward in the adjacent lower syringe. The moving motor 62'63 is preferably Frequency conversion according to the configuration of the present invention is: a needle (four) ..." electric motor. It is not available from the ring-type finishing machine; the lower needle barrel of the basic section of the syringe draw frame is usually a pair of two = draw frame (four) force roller and phase spinning zone, and the present invention is assigned to Two adjacent k out of a completely autonomous stretching unit 6, the stretching element 12 200932975 i = 'beam two way fixed to the base 6 ° -"known draw ... 'where the upper exit force The rollers are held against the continuous lower needle by a spring: the female solid extensions 70 have their respective outlet pressure roller pairs. Therefore, the configuration of the adjacent stretching unit is no longer extended by a continuous 锖#% with a continuous linear lower needle cylinder as a straight line as a right outer outlet pressure roller, and the corresponding mutual extension unit can be independent of the adjacent stretching unit. The autonomous operation of the autonomous operation == machine is preferably set at an angle to its adjacent unit. , yarn. All of the weaving zones of the knitting machine can be supplied with the stretched coarseness. :: It can be seen in Figure 3 that a guiding element is placed on the conveying path from the inlet to the double apron 8. In particular, when all of the fibers comprising the short fiber loops and m are transferred, the excess stretch component is guided by the double skin m-rollers 81, 82. For the introduction of the roving or roving, at: the inlet #10 is provided at the entrance of the stretching unit 6. It includes a channel n in which the branch direction is tapered. The inlet lightly hits the upper pressure roller 71, 81 of the apron roller of the double apron 8 of the temple and the temple, and is forced against the relevant lower needle of the tensioning unit 75, 76, the elastic ^ U 1〇w, 79, 2. The upper outlet pressure point 91 is pressed against the lower outlet cylinder 92 by the steel plate. At the same time: 72::, 92 are driven by the electric motor 62, and extend on the base 60 and outward. The electric motor ^, 63 is the most synchronous electric motor operated by the frequency converter. The lower needle 胄Μ, Μ, Μ = the drive member is located behind the base 60 and is protected from contamination by a cover Μ (Fig. 3). The drive of the lower syringe 72' 82, 92 is shown in Figure 3 at 13 200932975 Ο. For this purpose, the shafts of the electric motors 62, 63 extend from the base 6'' and are driven by the drive pinions 65, 66. The shafts of the lower cylinders 72, 82, 92 cooperate with drive gears 74, 84, 94 located at the rear of the base 60. The timing belts 67, 68 connect the drive gear 74 of the lower cylinder to the drive pinions 65, 66 of the electric motor. The lower needle cylinder 72 of the inlet pressure roller pair 7 and the lower apron cylinder for the double apron 8 are here driven by the same drive electric motor 62. The edges of the preliminary stretch zone for the spun yarn are determined by the different diameters of the drive wheels 74, 84 such that the circumferential speeds of the two lower syringes 72, 82 are different. The diameter of the lower barrel is selected such that the initial stretch is approximately 12 or 1/4. The lower outlet cylinder 92 of the pair of outlet pressure rollers 9 is driven by the electric motor ’ to have a peripheral speed greater than the other two lower syringes. The different speeds between the double apron 8 and the outlet pressure roller 9 determine the stretch of the roving and its stretch factor is between 25 and 5 G. The fiber tampon is stretched to a predetermined extent at the exit pressure roller # The transport nip line of 9 is output, which can be supplied directly to the needle located in the syringe, or can be supplied to a twisting device that produces a false twist. Figure 5 shows the different elements of the lacquer from the perspective of the introduction of the roving according to the present invention. For the sake of clarity, the elements shown have the reference numerals as shown in Figures 2 to 4. In Fig. 5, the stretching unit 6 is used for pulling: the roving or (4) yarns conveyed by the strips are equal to each other. For this purpose (4), the silk burdock is provided with two adjustments for the roving of 5 丨 胄丨 该 该 该 该 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Instead of a wire guide 17 3 with two channels U, two wires 14 each adjacent to each other having a channel are provided. 200932975 The improved structure according to the invention allows the stretching unit to be applied to knitting: in particular, space A particularly compact circular knitting machine. Two adjacent braided common stretch sheets "provide a stretched fiber tampon. Also will pass a suitably sized roll or lower syringe, a corresponding number of configurations of wire guides or - wire guides have A corresponding number of channels are used to stretch more rovings at the same time. A 兀 兀 ❹ ❹ Figure 6 shows another stretching unit for stretching the so-called draw frame sliver. The draw tampon is none There is no need for a preliminary stretching zone. Therefore, the stretching unit does not have a separate inlet pressure roller pair. The lower outlet cylinder position = double apron, indicated by reference... due to the draw frame sliver Z spinning weight... The desired yarn fineness to be achieved by the stretching is as close as .1. The effect of the high-strength stretching is to make the stretched fiber tampon very wide after the double apron. The expanded fiber tampon is again polymerized to have a _ compression zone after the stretching zone. A & a guide roller 85 is provided between the upper apron roller 81 and the upper outlet pressure roller μ. The arrangement of the upper inlet pressure roller and the upper apron roller of the pair of inlet pressure rollers of the middle embodiment Similarly, the guide is lightly disposed on a separate assembly tray and like the upper outlet pressure roller 91_, on the outlet cylinder 92. The lower outlet cylinder 92 has a perforated outer casing. a fixing member against the inner surface of the outer casing. The component processing-cavity is coupled to a vacuum source and a groove facing the inner surface of the outer casing and extending beyond a circumferential distance of the lower outlet cylinder 92, the circumferential distance being from the The bite line of the guiding pro-85 of the π-cylinder 92 is lowered to the distance of the clamping line of the q-pressure report 9. The air is thereby exhausted by the longitudinal fixing groove through the perforation on the lower cover of the 200932975 2 pin and 92 The expanded fiber tampon is again subjected to traction polymerization under the influence of the air flow to a compressed state of 'the polymerized fiber tampon leaving the stretching unit at the clamping line of the pair of outlet pressure rolls 9.
