Description

Technical Field

[0001] The invention belongs to the technical field of textiles, in particular to a yarn doubling device for textile processing. Background Art

[0002] Parallel yarn is to combine two or more yarns together, and then use the parallel yarn machine to parallel them and make them into a composite yarn with specific properties and appearance. Parallel yarn can combine the advantages of different yarns, for example, paralleling high-strength yarn with soft yarn can obtain yarn with both high strength and good hand feel.

[0003] The basic principle of the doubling machine is to set up multiple bobbin holders on the doubling machine to place the single yarn bobbins to be doubling. After the single yarn is drawn out from the bobbin, it is first doubling by the doubling holder and then guided by the guide device. A winding device is set at the end of the guide device to wind up the composite yarn after doubling. At the same time, a reciprocating mechanism is set at the end of the guide device to drive the reciprocating movement of the guide device, so that the composite yarn after doubling can be evenly wound.

[0004] However, when the end of the guide device moves from the middle of the winding roller to the end of the winding roller, the distance between the composite yarn passing through the doubling frame and the end of the winding roller is greater than the distance between the composite yarn and the middle of the winding roller, and the unwinding speed of the bobbin will be accelerated. However, when the end of the guide device then moves from the end of the winding roller to the middle, the bobbin will maintain the original unwinding speed due to inertia. Since the winding speed of the winding roller remains unchanged and the end of the guide device moves from the end of the winding roller to the middle of the winding roller, the composite yarn will have a certain amount of excess (when the winding speed of the winding roller remains unchanged), which will cause the single yarn before the doubling frame to lag behind, and finally cause the composite yarn passing through the doubling frame to be uneven in thickness, partially loose or too tight (this situation will be more obvious when high-strength yarn and soft yarn are doubling).

[0005] Therefore, in order to solve the above problems, a yarn doubling device for textile processing is proposed. Summary of the invention

[0006] In order to solve the problems raised in the above background technology, the present invention provides a yarn doubling device for textile processing, which solves the problem that single yarns may lag behind during the doubling process, resulting in uneven thickness and local looseness of composite yarns.

[0008] Preferably, the top and bottom of the support are fixedly connected with internal spline ring blocks at equal distances, and the roller frame is movably connected to the support through two upper and lower ball support plates; A gasket is placed on the top of the winding cone, and a bolt threadedly connected to the roller frame is arranged above the gasket.

[0009] Preferably, the guide assembly comprises a connecting rod hinged to the middle of the support, the hinge axis of which is a rotating shaft, one end of the connecting rod close to the top and the axis is fixedly connected to a wire drawing frame, and the other end of the connecting rod is movably mounted with a wire drawing wheel; The reciprocating screw assembly is also provided with a protruding rod, which passes through the straight slot and is movably connected to the connecting rod.

[0011] Preferably, the two side walls of the vertical slot are in an "eight" shape, and the columnar portion of the frame is initially located at the bottom of the vertical slot and the axis is located above the horizontal slot.

[0012] Preferably, the pressing plate body is provided with circular holes at equal intervals, the circular holes are movably sleeved on the top of the connecting shaft, and the diameters of both holes are larger than the diameter of the tension spring combined spline shaft; The top of the connecting shaft is connected to the bearing of the pressing plate body.

[0013] Preferably, the fan blade assembly comprises a connecting ring fixedly connected to the bottom of the connecting shaft, and the connecting ring is provided with a fan blade body in an annular array and hingedly connected thereto. The fan blade body is always in an inclined state, and in an initial state, the fan blade body has a larger inclination angle; An annular groove is provided inside the tank body, and an elastic convex shaft having one end sliding in the annular groove is elastically supported on the top of the fan blade body.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The above scheme drives the end of the guide assembly to move from the middle of the winding assembly to the end portion through the reciprocating screw assembly. At this time, the connecting rod rotates through the rotating shaft to drive the U-shaped frame to rotate, and the columnar part of the frame will be squeezed by the side wall of the vertical groove and enter the horizontal groove. When the line-dividing wheel is completely moved to the end of the winding assembly, the frame will be reset upward by the tension of the tension member, and the columnar part of the frame will enter the inclined groove. When the line-dividing wheel rotates in the opposite direction, the columnar part of the frame will move along the inclined groove and force the arc block and the pressure plate body to move downward, so that the fan blade assembly contacts the hydraulic oil when the connecting shaft goes downward, thereby increasing the resistance of the fan blade assembly, and then reducing the rotation speed of the connecting shaft, the tension spring combined spline shaft and the roller frame, avoiding the winding bobbin from unwinding too fast under the action of inertia, and avoiding the lag of the single yarn and the uneven thickness and local looseness of the composite yarn. The above scheme drives the wiring wheel to rotate to the middle of the winding assembly through the connecting rod, and the columnar part of the frame will enter the top of the vertical slot from the top of the inclined slot. At this time, under the action of the tension of the tension spring combined spline shaft, the connecting shaft will be pulled upward to reset and drive the pressure plate body to quickly reset. At this time, the columnar part of the frame can move from the bottom of the vertical slot to the horizontal slot. At this time, the buffer mechanism will no longer move downward and generate resistance to the pay-off mechanism, thereby ensuring that when the end of the guide assembly moves toward the end of the winding assembly, the increase in the pay-off speed of the pay-off mechanism will not cause the single yarn to break.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 12 As shown, the present invention provides a yarn doubling device for textile processing, comprising a support 1 and a winding assembly 7, wherein the support 1 comprises a tank body 12 and a limiting column 13 fixedly connected to the bottom of a straight slot 11 at equal intervals, wherein hydraulic oil is stored in the tank body 12, and further comprises: a pay-off mechanism 2, which is equidistantly installed on the support 1; a guide assembly 4, which is hinged to the middle of the support 1 and is used to evenly guide the composite yarn to the winding assembly 7; a buffer mechanism 3, which is movably installed inside the tank body 12 and is used to reduce the rotational inertia of the pay-off mechanism 2 when descending; a reciprocating screw assembly 6, which is installed at the bottom of the support 1 and is used to drive the guide assembly 4; a transmission mechanism 5, which is arranged on the guide assembly 4 and is used to link the buffer mechanism 3 to slowly descend and quickly rebound and reset; The wire-releasing mechanism 2 comprises a roller frame 21 movably mounted inside the support 1, a winding bobbin 23 is sleeved on the roller frame 21, and the winding bobbin 23 is fixed by a fixing assembly 22 arranged on the roller frame 21, and a tension spring combined spline shaft 24 is elastically connected to the bottom of the roller frame 21; The buffer mechanism 3 includes a connecting shaft 31 movably connected to the tank body 12, the top of the connecting shaft 31 extends above the tank body 12 and is fixedly connected to the bottom of the tension spring combined spline shaft 24, and the bottom of the connecting shaft 31 is fixedly connected to a fan blade assembly 32 initially located above the hydraulic oil; The guide assembly 4 includes a connecting rod 41 hinged to the middle of the support 1, and its hinge axis is a rotating shaft 411. A wire drawing frame 42 is fixedly connected to one end of the connecting rod 41 near the top and the axis, and a wire drawing wheel 43 is movably installed at the other end of the connecting rod 41. The reciprocating screw assembly 6 is also provided with a protruding rod 61, which passes through the straight slot 11 and is movably connected to the connecting rod 41; The transmission mechanism 5 includes a pressure plate body 51 located below the support 1 and sleeved on the limiting column 13. An arc block 52 is fixedly connected to one side of the pressure plate body 51. A U-shaped frame 53 is fixedly connected to the bottom of the rotating shaft 411. A tension member 54 and a frame 56 are also movably sleeved on the rotating shaft 411. The tension member 54 is fixedly connected between the top of the frame 56 and the U-shaped frame 53. A limiting rod 55 movably sleeved on the frame 56 is also fixedly connected inside the U-shaped frame 53. The arc block 52 is provided with a horizontal groove 521, two groups of inclined grooves 522 and a vertical groove 523. The bottom ends of the two groups of inclined grooves 522 are respectively connected to the two ends of the horizontal groove 521, the top end of the vertical groove 523 is connected to the top ends of the two groups of inclined grooves 522, and the bottom end of the vertical groove 523 is connected to the middle of the horizontal groove 521. One end of the frame 56 is columnar and extends into the horizontal groove 521 and can slide in the horizontal groove 521, the inclined groove 522 and the vertical groove 523 respectively; The pressing plate body 51 is provided with circular holes 511 at equal intervals. The circular holes 511 are movably sleeved on the top of the connecting shaft 31 and the diameters of the circular holes 511 are larger than the diameter of the tension spring combined spline shaft 24. The top of the connecting shaft 31 is connected to the pressing plate body 51 by a bearing.

[0020] By adopting the above scheme, the end of the guide assembly 4 is driven by the reciprocating screw assembly 6 to move from the middle of the winding assembly 7 to the end. At this time, the connecting rod 41 rotates through the rotating shaft 411 to drive the U-shaped frame 53 to rotate, and the columnar part of the frame body 56 is squeezed by the side wall of the vertical groove 523 and enters the horizontal groove 521. When the line-dividing wheel 43 is completely moved to the end of the winding assembly 7, the frame body 56 is pulled upward by the tension member 54 and reset, and the columnar part of the frame body 56 enters the inclined groove 522, and the line-dividing wheel 4 When rotating in the reverse direction, the columnar part of the frame 56 will move along the inclined groove 522 and force the arc block 52 and the pressure plate body 51 to move downward, so that the connecting shaft 31 moves downward and the fan blade assembly 32 contacts the hydraulic oil, thereby increasing the resistance of the fan blade assembly 32, thereby reducing the rotation speed of the connecting shaft 31, the tension spring combined spline shaft 24 and the roller frame 21, avoiding the winding 23 from releasing the wire too fast under the action of inertia, and avoiding the hysteresis of the single yarn and the uneven thickness and local looseness of the composite yarn; Since the pressing plate body 51 is connected to the connecting shaft 31 by a bearing, the friction between the pressing plate body 51 and the top of the connecting shaft 31 can be reduced when the pressing plate body 51 is pressed down, so as to avoid the situation in which the friction between the pressing plate body 51 and the connecting shaft 31 is too large when the subsequent device is fully reset, resulting in excessive resistance when the pay-off mechanism 2 rotates as a whole; When the connecting rod 41 drives the winding wheel 43 to rotate to the middle of the winding assembly 7, the columnar part of the frame 56 will enter the top of the vertical groove 523 from the top of the inclined groove 522. At this time, under the action of the tension of the tension spring combination spline shaft 24, the connecting shaft 31 will be pulled upward to reset and drive the pressure plate body 51 to quickly reset. At this time, the columnar part of the frame 56 can move from the bottom of the vertical groove 523 to the horizontal groove 521. At this time, the buffer mechanism 3 will no longer move downward and generate resistance to the pay-off mechanism 2, thereby ensuring that when the end of the guide assembly 4 moves toward the end of the winding assembly 7, the increase in the pay-off speed of the pay-off mechanism 2 will not cause the single yarn to break.

[0021] like Figure 4 and Figure 7 As shown, the top and bottom of the support 1 are fixedly connected with internal spline ring blocks 221 at equal distances, and the roller frame 21 is movably connected to the support 1 through two upper and lower ball support plates 211; A gasket 222 is placed on the top of the winding cone 23, and a bolt 223 threadedly connected to the roller frame 21 is arranged above the gasket 222; By adopting the above solution, the bobbin 23 can be stably fixed on the roller frame 21 through the bolts 223, the internal spline ring block 221 and the gasket 222, so as to ensure the synchronization of the roller frame 21 and the bobbin 23 when rotating.

[0022] like Figure 6 , Figure 8 and Fig. 9As shown, the two side walls of the vertical slot 523 are in an "eight" shape, and the columnar portion of the frame 56 is initially located at the bottom of the vertical slot 523 and the axis is located above the horizontal slot 521; By adopting the above scheme, the two side walls of the vertical groove 523 are designed in an "eight" shape. When the columnar part of the frame 56 moves along the bottom of the vertical groove 523, the bottom of the vertical groove 523 can force the columnar part of the frame 56 to enter the horizontal groove 521, and then when the columnar part of the frame 56 slides to the end of the horizontal groove 521, it can enter the inclined groove 522.

[0023] like Figure 3-5 , Figure 7 and Fig.11 As shown, the fan blade assembly 32 includes a connecting ring 321 fixedly connected to the bottom of the connecting shaft 31, and a fan blade body 322 is hingedly connected to the connecting ring 321 in an annular array. The fan blade body 322 is always in an inclined state, and the inclination angle of the fan blade body 322 is larger in the initial state; An annular groove 121 is provided inside the tank body 12, and an elastic convex shaft 323 having one end sliding in the annular groove 121 is elastically supported on the top of the fan blade body 322; By adopting the above scheme, the connecting ring 321 is synchronously driven downward by the connecting shaft 31, and the height of the top of the blade body 322 will remain unchanged. At this time, the inclination angle of the blade body 322 will be reduced, and at the same time, the contact area of ​​the bottom of the blade body 322 with the hydraulic oil will increase, so that the line-dividing wheel 43 is reset from the end of the winding assembly 7 to the middle. When the line-dividing wheel 43 is closer to the middle of the winding assembly 7, the resistance encountered by the pay-off mechanism 2 from the buffer mechanism 3 is greater, thereby further slowing down the inertia of the pay-off mechanism 2 during rotation.

[0024] like Figure 5 and Fig.11 As shown, the tank body 12 is also provided with an annular array of arc plates 122 fixed thereto. The arc plates 122 are located above the hydraulic oil, and a gap is left between the arc plates 122 and the fan blade body 322. The head and tail ends of two adjacent arc plates 122 are staggered. By adopting the above solution, through the design of the arc plate 122, it is possible to avoid the vortex edge generated by the blade body 322 being too high, thereby causing resistance to the blade body 322 when the blade body 322 is subsequently reset upward.

[0025] The working principle and use process of the present invention: First, the operator fixes the bobbin 23 on the roller frame 21 through the fixing assembly 22, so that the bobbin 23 and the roller frame 21 can rotate synchronously, and the single yarn on the bobbin 23 passes through the doubling frame 42 and the doubling wheel 43 for doubling, and the composite yarn is wound through the winding assembly 7, and the reciprocating screw assembly 6 drives the protruding rod 61 to reciprocate in the tank body 12 to make the connecting rod 41 reciprocate around the rotating shaft 411 as the axis, so that the doubling wheel 43 can reciprocate under the winding assembly 7, so that the composite yarn is evenly wound on the winding assembly 7; When the line-integrating wheel 43 moves from the middle part of the winding assembly 7 to the end part, the connecting rod 41 rotates through the rotating shaft 411 to drive the U-shaped frame 53 to rotate, and the columnar part of the frame 56 will be squeezed by the side wall of the vertical groove 523 and enter the horizontal groove 521. When the line-integrating wheel 43 completely moves to the end of the winding assembly 7, the frame 56 will be reset upward by the pulling force of the tension member 54, and the columnar part of the frame 56 will enter the inclined groove 522. When the line-integrating wheel 43 rotates in the opposite direction, the columnar part of the frame 56 will move along the inclined groove 522 and force the arc block 52 and the pressure plate body 51 to move downward, so that the connecting shaft 31 moves downward and the fan blade assembly 32 contacts with the hydraulic oil, thereby increasing the resistance of the fan blade assembly 32, and then reducing the rotation speed of the connecting shaft 31, the tension spring combination spline shaft 24 and the roller frame 21, so as to avoid the situation that the winding 23 is too fast in the release speed under the action of inertia and causes the single yarn to lag. When the connecting rod 41 drives the doubling wheel 43 to rotate to the middle of the winding assembly 7, the columnar part of the frame 56 will enter the top of the vertical slot 523 from the top of the inclined slot 522. At this time, under the tension of the tension spring combined spline shaft 24, the connecting shaft 31 will be pulled upward to reset and drive the pressure plate body 51 to quickly reset. At this time, the columnar part of the frame 56 can move from the bottom of the vertical slot 523 to the horizontal slot 521. At this time, the buffer mechanism 3 will not go down again and generate resistance to the pay-off mechanism 2, thereby ensuring that when the end of the guide assembly 4 moves toward the end of the winding assembly 7, the increase in the pay-off speed of the pay-off mechanism 2 will not cause the single yarn to break; The downward movement of the connecting shaft 31 synchronously drives the connecting ring 321 downward, while the height of the top of the blade body 322 remains unchanged. At this time, the inclination angle of the blade body 322 will decrease, and at the same time, the contact area of ​​the bottom of the blade body 322 with the hydraulic oil will increase, thereby making the line-dividing wheel 43 reset from the end of the winding assembly 7 to the middle. In the process, the closer the line-dividing wheel 43 is to the middle of the winding assembly 7, the greater the resistance that the unwinding mechanism 2 encounters from the buffer mechanism 3 until the line-dividing wheel 43 is close to the middle of the winding assembly 7, and the buffer mechanism 3 is quickly reset.
