A yarn doubling device for textile processing

Abstract

The present invention belongs to the field of textile technology and discloses a yarn doubling device for textile processing, which includes a support and a winding assembly. The support includes a tank body and a limiting column fixedly connected to the bottom of the straight groove opening at equal intervals. Hydraulic oil is stored inside the tank body. It further includes: a wire unwinding mechanism, which is installed on the support at equal intervals. Through the reciprocating lead screw assembly in the above solution, the end of the guiding assembly is driven to approach from the middle to the end of the winding assembly. At this time, the connecting rod rotates to drive the U-shaped frame to rotate through the rotating shaft. When the doubling wheel rotates in the reverse direction, the columnar part of the frame body will move along the inclined groove and force the arc-shaped block and the pressing plate body to move downward, so that the connecting shaft moves downward to make the fan blade assembly contact the hydraulic oil, thereby increasing the resistance of the fan blade assembly, and further reducing the rotation speed of the connecting shaft, the combined spline shaft of the tension spring and the roller frame, avoiding the wire unwinding speed of the winding bobbin being too fast under the action of inertia, and avoiding the situation of single yarn lag, uneven thickness of the composite yarn and local looseness.

Description

Technical Field

[0001] The present invention belongs to the technical field of textiles, and specifically relates to a yarn doubling device for textile processing. Background Art

[0002] Doubling is the process of combining two or more yarns together and making them into a composite yarn with specific properties and appearance through a doubling machine. By doubling, the advantages of different yarns can be combined. For example, doubling a high-strength yarn with a soft yarn can obtain a yarn with both high strength and good handfeel.

[0003] The basic principle of a doubling machine is to set multiple yarn bobbin holders on the doubling machine for placing single yarn bobbins to be doubled. The single yarns are led out from the bobbins, first doubled by a doubling frame, and then guided by a guiding device. A winding device is provided at the end of the guiding device to wind the doubled composite yarn. At the same time, a reciprocating mechanism is also provided at the end of the guiding device to drive the reciprocating movement of the guiding device, so that the doubled composite yarn can be evenly wound.

[0004] However, when the end of the guiding device moves from the middle of the winding roller to the end of the winding roller, the distance from the composite yarn passing through the doubling frame to the end of the winding roller is greater than the distance from the middle of the winding roller. At this time, the unwinding speed of the winding bobbin will increase. But then when the end of the guiding device moves from the end of the winding roller to the middle, the winding bobbin will maintain the original unwinding speed under the action of inertia. Since the winding speed of the winding roller remains unchanged, and when the end of the guiding device moves from the end of the winding roller to the middle of the winding roller, it will cause a section of surplus of the composite yarn (under the condition that the winding speed of the winding roller remains unchanged), which will in turn cause the single yarn before the doubling frame to lag, and finally lead to uneven thickness, local looseness or tightness of the composite yarn passing through the doubling frame (this situation will be more obvious when doubling a high-strength yarn with a soft yarn).

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

[0006] To solve the problems raised in the above background art, the present invention provides a yarn doubling device for textile processing, which solves the problem that the single yarn will lag during the doubling process, resulting in uneven thickness and local looseness of the composite yarn.

[0007] To achieve the above object, the present invention provides the following technical solutions: A yarn doubling device for textile processing, including a support and a winding assembly. The support includes a tank body and a limit post fixedly connected at equal intervals to the bottom of the straight groove opening. Hydraulic oil is stored inside the tank body. It further includes: a wire releasing mechanism, which is installed on the support at equal intervals; a guiding assembly, which is hinged to the middle of the support for evenly guiding the composite yarn onto the winding assembly; a buffering mechanism, which is movably installed inside the tank body for reducing the rotational inertia of the wire releasing mechanism when descending; a reciprocating lead screw assembly, which is installed at the bottom of the support for driving the guiding assembly; a transmission mechanism, which is arranged on the guiding assembly for linking the buffering mechanism to slowly descend and quickly rebound and reset;

[0008] The wire releasing mechanism includes a roller frame movably installed inside the support. A bobbin is sleeved on the roller frame. The bobbin is fixed by a fixing component arranged on the roller frame. The bottom of the roller frame is elastically connected with a tension spring combined spline shaft;

[0009] The buffering mechanism includes a connecting shaft movably connected to the tank body. The top end of the connecting shaft extends above the tank body and is fixedly connected to the bottom end of the tension spring combined spline shaft. A fan blade assembly initially located above the hydraulic oil is fixedly connected to the bottom of the connecting shaft.

[0010] Preferably, internal spline circular blocks are fixedly connected at equal intervals to the top and bottom of the support. The roller frame is movably connected to the support through upper and lower ball bearing support plates;

[0011] A gasket is placed on the top of the bobbin. A bolt threadedly connected to the roller frame is arranged above the gasket.

[0012] Preferably, the guiding assembly includes a connecting rod hinged to the middle of the support. Its hinge axis is a rotating shaft. A doubling frame is fixedly connected to one end of the connecting rod near the top and close to the axis. A doubling wheel is movably installed at the other end of the connecting rod;

[0013] A convex rod is further arranged on the reciprocating lead screw assembly. The convex rod penetrates through the straight groove opening and is movably connected to the connecting rod.

[0014] Preferably, the transmission mechanism includes a pressing plate body located below the support and sleeved on the limit post. An arc-shaped block is fixedly connected to one side of the pressing plate body. A U-shaped frame is fixedly connected to the bottom of the rotating shaft. A tension member and a frame body are also movably sleeved on the rotating shaft. The tension member is fixedly connected between the top of the frame body and the U-shaped frame. A limit rod movably sleeved on the frame body is further fixedly connected inside the U-shaped frame;

[0015] A horizontal groove, two groups of inclined grooves and a vertical groove are formed on the arc-shaped block. The bottom ends of the two groups of inclined grooves are respectively communicated with both ends of the horizontal groove. The top end of the vertical groove is communicated with the top ends of the two groups of inclined grooves, and the bottom end of the vertical groove is communicated with the middle of the horizontal groove;

[0016] One end of the frame body is columnar and extends into the horizontal groove and can slide in the horizontal groove, inclined groove and vertical groove respectively.

[0017] Preferably, the two side walls of the vertical groove are in a "V" shape, and the columnar part of the frame body is initially located at the bottom of the vertical groove and its axis is above the horizontal groove.

[0018] Preferably, round holes are equidistantly arranged on the pressing plate body, and the round holes are movably sleeved on the top of the connecting shaft, and the diameters of both are larger than the diameter of the spring combination spline shaft;

[0019] The top of the connecting shaft is connected to the pressing plate body by a bearing.

[0020] Preferably, the fan blade assembly includes a connecting ring fixedly connected to the bottom of the connecting shaft. Fan blade bodies are annularly arrayed and hinged on the connecting ring. The fan blade bodies are always in an inclined state, and the inclination angle of the fan blade bodies is larger in the initial state;

[0021] An annular groove is formed inside the tank body, and an elastic convex shaft with one end sliding in the annular groove is elastically supported at the top of the fan blade body.

[0022] Preferably, arc-shaped plates are also annularly arrayed and fixedly connected inside the tank body. The arc-shaped plates are located above the hydraulic oil, and there is a gap between the arc-shaped plates and the fan blade bodies; the head and tail ends of two adjacent arc-shaped plates are arranged in a staggered manner.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] In the above solution, the reciprocating lead screw assembly drives the end of the guiding assembly to approach from the middle to the end of the winding assembly. At this time, the connecting rod rotates and drives the U-shaped frame to rotate through the rotating shaft. The columnar part of the frame body will be squeezed by the side wall of the vertical groove and enter the horizontal groove. When the wire combining wheel completely moves to the end of the winding assembly, the frame body will be pulled upward and reset under the action of the tension member. The columnar part of the frame body will enter the inclined groove. When the wire combining wheel rotates in the reverse direction, the columnar part of the frame body will move along the inclined groove and force the arc-shaped block and the pressing plate body to move downward, so that the connecting shaft moves downward to make the fan blade assembly contact the hydraulic oil, thereby increasing the resistance of the fan blade assembly, and further reducing the rotation speed of the connecting shaft, the spring combination spline shaft and the roller frame, avoiding the situation that the unwinding speed of the winding bobbin is too fast due to inertia, and avoiding the situation of single yarn lag, uneven thickness of composite yarn and local looseness;

[0025] The above solution drives the wire-winding wheel to rotate to the middle of the winding assembly through the connecting rod. The columnar part of the frame body will enter from the top of the inclined groove to the top of the vertical groove. At this time, under the action of the pulling force of the tension spring combined spline shaft, the connecting shaft will be pulled upward to reset and drive the platen body to quickly reset. At this time, the columnar part of the frame body can move from the bottom of the vertical groove into the horizontal groove. At this time, the buffer mechanism will no longer move downward and generate resistance to the wire-feeding mechanism, thereby ensuring that when the end of the guiding assembly moves towards the end of the winding assembly, the increase in the wire-feeding speed of the wire-feeding mechanism will not cause the single yarn to break.

[0039] 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.

[0040] 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 the tank body 12 stores hydraulic oil, 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;

[0041] 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;

[0042] 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;

[0043] The guiding component 4 includes a connecting rod 41 hinged to the middle of the support 1, with its hinge axis being the rotating shaft 411. A wire combining frame 42 is fixedly connected to one end of the connecting rod 41 near the top and close to the axis, and a wire combining wheel 43 is movably installed at the other end of the connecting rod 41;

[0044] A convex rod 61 is also provided on the reciprocating lead screw assembly 6. The convex rod 61 penetrates through the straight notch 11 and is movably connected to the connecting rod 41;

[0045] The transmission mechanism 5 includes a pressing plate body 51 located below the support 1 and sleeved on the limiting column 13. An arc-shaped block 52 is fixedly connected to one side of the pressing 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 body 56 are also movably sleeved on the rotating shaft 411. The tension member 54 is fixedly connected between the top of the frame body 56 and the U-shaped frame 53. A limiting rod 55 movably sleeved on the frame body 56 is also fixedly connected inside the U-shaped frame 53;

[0046] A horizontal groove 521, two inclined grooves 522, and a vertical groove 523 are formed on the arc-shaped block 52. The bottom ends of the two inclined grooves 522 are respectively communicated with both ends of the horizontal groove 521. The top end of the vertical groove 523 is communicated with the top ends of the two inclined grooves 522, and the bottom end of the vertical groove 523 is communicated with the middle of the horizontal groove 521;

[0047] One end of the frame body 56 is columnar and extends into the horizontal groove 521 and can slide in the horizontal groove 521, the inclined grooves 522, and the vertical groove 523 respectively;

[0048] Circular holes 511 are equidistantly formed on the pressing plate body 51. The circular holes 511 are movably sleeved on the top of the connecting shaft 31, and both of their diameters are larger than the diameter of the spring combination spline shaft 24;

[0049] The top of the connecting shaft 31 is connected to the pressing plate body 51 by a bearing.

[0050] Adopting the above scheme, the reciprocating lead screw assembly 6 drives the end of the guiding component 4 to approach from the middle of the winding component 7 to the end. At this time, the connecting rod 41 rotates and drives the U-shaped frame 53 to rotate through the rotating shaft 411. The columnar part of the frame body 56 will be squeezed by the side wall of the vertical groove 523 and enter into the horizontal groove 521. When the wire combining wheel 43 completely moves to the end of the winding component 7, the frame body 56 will move upward and reset under the pulling force of the tension member 54. The columnar part of the frame body 56 will enter into the inclined groove 522. When the wire combining wheel 43 rotates in the reverse direction, the columnar part of the frame body 56 will move along the inclined groove 522 and force the arc-shaped block 52 and the pressing plate body 51 to move downward, so that the connecting shaft 31 moves downward to make the fan blade assembly 32 contact with the hydraulic oil, thereby increasing the resistance of the fan blade assembly 32, and further reducing the rotation speed of the connecting shaft 31, the spring combination spline shaft 24, and the roller frame 21, avoiding the situation that the winding speed of the bobbin 23 is too fast due to inertia, and avoiding the situation of single yarn lag, uneven thickness of composite yarn, and local looseness;

[0051] Since the pressing plate body 51 is connected to the connecting shaft 31 by bearings, it can reduce the friction between the pressing plate body 51 and the top of the connecting shaft 31 when the pressing plate body 51 presses downwards, and avoid the situation that when the subsequent device is fully reset, the friction between the pressing plate body 51 and the connecting shaft 31 is too large, resulting in too much resistance when the wire releasing mechanism 2 rotates as a whole.

[0052] When the connecting rod 41 drives the wire combining wheel 43 to rotate to the middle of the winding assembly 7, the columnar part of the frame body 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 pulling force of the tension spring combined spline shaft 24, the connecting shaft 31 will be pulled upward to reset and drive the pressing plate body 51 to quickly reset. At this time, the columnar part of the frame body 56 can move from the bottom of the vertical groove 523 into the horizontal groove 521. At this time, the buffer mechanism 3 will no longer move downward and generate resistance to the wire releasing mechanism 2, thereby ensuring that when the end of the guiding assembly 4 moves towards the end of the winding assembly 7, the increase in the wire releasing speed of the wire releasing mechanism 2 will not cause the single yarn to break.

[0053] As Figure 4 and Figure 7 As shown, equally spaced internal spline ring blocks 221 are fixedly connected to the top and bottom of the support 1, and the roller frame 21 is movably connected to the support 1 through upper and lower two ball support plates 211;

[0054] A gasket 222 is placed on the top of the winding bobbin 23, and a bolt 223 threadedly connected to the roller frame 21 is arranged above the gasket 222;

[0055] Adopting the above scheme, the winding bobbin 23 can be stably fixed on the roller frame 21 through the bolt 223, the internal spline ring block 221 and the gasket 222 to ensure the synchronism when the roller frame 21 and the winding bobbin 23 rotate.

[0056] As Figure 6 、 Figure 8 and Figure 9 As shown, the two side walls of the vertical groove 523 are in a "V" shape, and the columnar part of the frame body 56 is initially located at the bottom of the vertical groove 523 and its axis is above the horizontal groove 521;

[0057] Adopting the above scheme, through the design that the two side walls of the vertical groove 523 are in a "V" shape, when the columnar part of the frame body 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 body 56 to enter the horizontal groove 521, and then when the columnar part of the frame body 56 slides to the end of the horizontal groove 521, it can enter the inclined groove 522.

[0058] As Figures 3 - 5 、 Figure 7 and Figure 11As shown, the fan blade assembly 32 includes a connecting ring 321 fixedly connected to the bottom of the connecting shaft 31. The fan blade bodies 322 are annularly arrayed and hinged on the connecting ring 321. The fan blade bodies 322 are always in an inclined state, and the inclination angle of the fan blade bodies 322 is larger in the initial state.

[0059] An annular groove 121 is formed inside the tank body 12. An elastic convex shaft 323 with one end sliding in the annular groove 121 is elastically supported at the top of the fan blade body 322.

[0060] With the above scheme, when the connecting shaft 31 moves downward synchronously, the connecting ring 321 is driven to move downward. While the height of the top of the fan blade body 322 remains unchanged, the inclination angle of the fan blade body 322 will decrease at this time. At the same time, the contact area between the bottom of the fan blade body 322 and the hydraulic oil will increase. Thus, when the wire combining wheel 43 is reset from the end of the winding assembly 7 to the middle, the closer the wire combining wheel 43 is to the middle of the winding assembly 7, the greater the resistance exerted on the wire releasing mechanism 2 by the buffer mechanism 3, further slowing down the inertia when the wire releasing mechanism 2 rotates.

[0061] As Figure 5 and Figure 11 shown, arc-shaped plates 122 are also annularly arrayed and fixedly connected inside the tank body 12. The arc-shaped plates 122 are located above the hydraulic oil, and there is a gap between the arc-shaped plates 122 and the fan blade bodies 322. The head and tail ends of adjacent two arc-shaped plates 122 are arranged staggeredly.

[0062] With the above scheme, through the design of the arc-shaped plates 122, it can avoid the situation that the edge of the vortex generated by the fan blade body 322 is too high, which may cause resistance to the fan blade body 322 when the fan blade body 322 moves upward and resets later.

[0063] The working principle and usage process of the present invention:

[0064] First, the operator fixes the bobbin 23 on the roller frame 21 through the fixing component 22, so that the bobbin 23 and the roller frame 21 can rotate synchronously. The single yarn on the bobbin 23 is passed through the wire combining frame 42 and the wire combining wheel 43 for wire combining. The composite yarn is wound by the winding assembly 7. Then, the reciprocating lead screw assembly 6 is operated to drive the convex rod 61 to reciprocate in the tank body 12, so that the connecting rod 41 rotates reciprocally around the rotating shaft 411, thereby enabling the wire combining wheel 43 to reciprocate below the winding assembly 7, so that the composite yarn is evenly wound on the winding assembly 7.

[0065] During the process of the coiling wheel 43 moving from the middle of the winding assembly 7 to the end part, the connecting rod 41 rotates to drive the U-shaped frame 53 to rotate through the rotating shaft 411. The columnar part of the frame body 56 will be squeezed by the side wall of the vertical groove 523 and enter into the horizontal groove 521. When the coiling wheel 43 completely moves to the end of the winding assembly 7, the frame body 56 will move upward and reset under the pulling force of the tension member 54. The columnar part of the frame body 56 will enter into the inclined groove 522. When the coiling wheel 43 rotates in the reverse direction, the columnar part of the frame body 56 will move along the inclined groove 522 and force the arc-shaped block 52 and the pressure plate body 51 to move downward, so that the connecting shaft 31 moves downward to make the fan blade assembly 32 contact with the hydraulic oil, thereby increasing the resistance of the fan blade assembly 32, and further reducing the rotation speed of the connecting shaft 31, the combined spline shaft 24 of the tension spring and the roller frame 21, and avoiding the situation that the single yarn lags behind due to the too fast unwinding speed of the bobbin 23 under the action of inertia;

[0066] When the connecting rod 41 drives the coiling wheel 43 to rotate to the middle of the winding assembly 7, the columnar part of the frame body 56 will enter from the top of the inclined groove 522 to the top of the vertical groove 523. At this time, under the action of the pulling force of the combined spline shaft 24 of the tension spring, the connecting shaft 31 will be pulled upward and reset to drive the pressure plate body 51 to quickly reset. At this time, the columnar part of the frame body 56 can move from the bottom of the vertical groove 523 into the horizontal groove 521. At this time, the buffer mechanism 3 will no longer move downward and generate resistance to the unwinding mechanism 2, and further ensure that when the end of the guiding assembly 4 moves to the end of the winding assembly 7, the increase in the unwinding speed of the unwinding mechanism 2 will not cause the single yarn to break;

[0067] The downward movement of the connecting shaft 31 drives the connecting ring 321 to move downward synchronously, while the height of the top of the fan blade body 322 remains unchanged. At this time, the inclination angle of the fan blade body 322 will decrease, and at the same time, the contact area between the bottom of the fan blade body 322 and the hydraulic oil will increase. Thus, when the coiling wheel 43 resets from the end of the winding assembly 7 to the middle, the closer the coiling wheel 43 is to the middle of the winding assembly 7, the greater the resistance exerted on the unwinding mechanism 2 by the buffer mechanism 3 until the buffer mechanism 3 quickly resets when the coiling wheel 43 is close to the middle of the winding assembly 7.

[0068] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
