Description

Technical Field

[0001] The invention relates to the technical field of spinning equipment, in particular to a blended yarn production equipment. Background Art

[0002] Spinning is the process of processing fibers (such as cotton, wool, silk, etc.) into yarns through stretching, twisting and twisting. The production of blended yarns requires ensuring that the proportion and structure of different fibers meet the expected requirements. Special blended yarn equipment can accurately control the mixing ratio, fiber length and fiber ratio of various fibers to meet specific product requirements.

[0003] When the blended yarn equipment is running, the friction between its internal pulley and the yarn and fiber is too large or uneven, which may cause inaccurate winding tension control, resulting in the wound yarn or fiber presenting an irregular shape on the winding roller, affecting subsequent processing or use. Inaccurate winding tension control or poor stability may also cause the winding tension of the yarn or fiber to be too large or too small, affecting product quality.

[0004] Therefore, a novel blended yarn production equipment can be adopted to solve the shortcomings of the prior art. Summary of the invention

A position adjustment mechanism is installed between the electromagnet 1 and the control cabinet. A limit track is fixedly installed on one side of the control cabinet, and a magnet 1 used in conjunction with the electromagnet 1 is installed on the limit track through a sliding mechanism. The sliding mechanism is installed with a fixed sleeve through a rotating component, and a preliminary adjustment mechanism is installed on the fixed sleeve.

The electromagnet 2 is fixedly connected to the limit track through a fixed ring plate, and a magnet 2 used in conjunction with the electromagnet 2 is installed on the sliding mechanism.

[0009] In the above-mentioned blended yarn production equipment, the winding mechanism includes a servo motor fixedly installed in a control cabinet, a fixed rod is fixedly installed on the driving end of the servo motor, and the fixed rod rotates through the panel, the part of the fixed rod located outside the control cabinet is installed with a driving roller through a fixing bolt, and a winding assembly is installed on the panel.

[0010] In the above-mentioned blended yarn production equipment, the winding assembly includes a tightening roller, two alignment rollers, a steering roller and two damping rollers rotatably mounted on a panel, and the steering roller is located at a middle and upper position between the two alignment rollers, and the two damping rollers are located below the corresponding alignment rollers and are attached to the corresponding alignment rollers. A support rod is fixedly mounted on one side of the control cabinet, and a straightening roller is rotatably mounted on the support rod.

[0011] In the above-mentioned blended yarn production equipment, the straightening roller and the steering roller are located on the same vertical line, and the rotation direction of the straightening roller and the rotation direction of the steering roller are perpendicular to each other.

[0012] In the above-mentioned blended yarn production equipment, the sensing mechanism includes a tension sensor fixedly installed on the side of the panel close to the control cabinet, the panel is provided with a through hole, a rotating shaft is rotatably installed in the through hole, and a tension sensing roller used in conjunction with the tension sensor is fixedly installed on the end of the rotating shaft away from the control cabinet.

[0013] In the above-mentioned blended yarn production equipment, the position adjustment mechanism includes an annular block fixedly installed on one side of the control cabinet, an electric push rod fixedly installed in the annular block, a connecting rod fixedly installed on the driving end of the electric push rod, and an electromagnet is fixedly connected to the connecting rod.

[0014] In the above-mentioned blended yarn production equipment, the straight line where the electromagnet 1 and the magnet 1 are located is parallel to the length direction of the limiting track.

[0015] In the above-mentioned blended yarn production equipment, the sliding mechanism includes two grooves opened on the limiting track, and a mounting block is slidably installed in the two grooves, and magnet one and magnet two are fixedly connected to the mounting block, and a movable plate is fixedly installed on the mounting block.

[0016] In the above-mentioned blended yarn production equipment, the rotating assembly includes a movable block fixedly mounted on a movable plate, two connecting brackets are rotatably mounted on the movable block, connecting rings are rotatably mounted on the two connecting brackets, and the adjusting rod is fixedly connected to the connecting ring, a bearing is fixedly mounted on one side of the control cabinet, a mounting clamp is fixedly provided in the bearing, and the adjusting rod is fixedly mounted in the mounting clamp.

[0020] 2: This blended yarn production equipment has the advantage of secondary adjustment of tension when winding the blended yarn. The relative position of electromagnet 1 and magnet 1 can be adjusted by controlling the extension and shortening of the electric push rod, thereby realizing the adjustment of the suction and repulsion forces between electromagnet 1 and the fixed sleeve. The tension can be adjusted again without changing the current, thereby increasing the range of adjustable tension.

[0021] 3: This blended yarn production equipment has the advantage of eliminating the vibration caused by tension when winding the blended yarn. Through the cooperation of electromagnet 2 and magnet 2, when the tension is unstable and causes the adjusting rod to shake, electromagnet 2 and magnet 2 can generate suction or repulsion in the same direction of movement, thus solving the problem of friction affecting tension adjustment.

[0022] In summary, the present invention changes the current size and relative distance between the two magnetic forces, and uses two adjustment methods while cooperating with the tension sensor to accurately adjust the tension during yarn winding, and can offset the friction generated during tension adjustment, thereby improving the efficiency and stability of tension adjustment.

DETAILED DESCRIPTION

[0037] 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.

[0038] Reference Figure 1-Figure 5 , Fig.11 as well as Fig.12A blended yarn production device includes a control cabinet 1, the front side of the control cabinet 1 is open, the front side of the control cabinet 1 is fixed with a panel 2 by screws and nuts, and the length of the panel 2 is longer than the height of the control cabinet 1, the upper surface of the panel 2 is parallel to the upper surface of the control cabinet 1, and the panel 2 is provided with a control switch ( Figure 1 and Figure 2 As can be seen, it is used to control the operation of the overall equipment. A servo motor 22 is fixedly installed in the control cabinet 1. A round hole is provided on the panel 2. A fixing rod is fixedly installed on the driving end of the servo motor 22. The fixing rod passes through the round hole and is fixedly installed with a driving roller 5 through a fixing bolt 23. A threaded hole is provided on the driving roller 5, and a threaded groove is provided on the fixing rod. The fixing bolt 23 is threadedly installed in the threaded hole and the threaded groove in sequence to fix the driving roller 5. The fixing bolt 23 is rotated to separate it from the fixing rod, so that the driving roller 5 of different diameters can be replaced and the speed of the blended yarn winding can be adjusted.

[0039] A tension sensor 4 is fixedly installed on one side of the lower part of the panel 2 close to the control cabinet 1. A perforation is opened on the panel 2, and a rotating shaft is rotatably installed in the perforation. A tension sensing roller 3 is fixedly installed on the end of the rotating shaft away from the control cabinet 1. The tension sensor 4 is composed of a supporting structure equipped with sensitive elements (such as strain gauges, pressure sensors, etc.). The structure is directly or indirectly connected to the material to be tested (the tension sensing roller 3 and the rotating shaft). When tension is applied to the material to be tested, the supporting structure will produce corresponding deformation or pressure changes, thereby causing changes in the sensitive elements. These changes are captured by the sensor and converted into electrical signals, which can be displayed on the instrument or transmitted to the computer or control system after processing.

[0040] A semicircular plate (from Figure 2 It can be seen that the semicircular plate is not fixed to the control cabinet 1, and a tightening roller 6, two alignment rollers 7, a steering roller 13 and two damping rollers 14 are rotatably installed on the front side of the panel 2. The steering roller 13 is located in the middle and upper position of the two alignment rollers 7, and the two damping rollers 14 are located below the corresponding alignment rollers 7 and are in contact with the corresponding alignment rollers 7. When the two alignment rollers 7 rotate, they can rotate more evenly under the action of the damping rollers 14. On the production line, the damping roller 14 can be used as a tension control structure to control the tension of the conveying material by adjusting the friction force and the pressure of the material to ensure the tension stability in each link. The damping roller 14 can adjust the speed of the conveying material by adjusting the friction between the inner core and the outer layer of the material, thereby realizing speed matching and synchronous transmission at different parts of the production line, and playing a preliminary role in adjusting the tension of the yarn.

[0041] A support rod is fixedly installed on one side of the control cabinet 1, and a straightening roller 8 is rotatably installed on the support rod, and the straightening roller 8 and the steering roller 13 are on the same vertical line. The rotation direction of the straightening roller 8 and the rotation direction of the steering roller 13 are perpendicular to each other, and the winding direction of the yarn on the straightening roller 8 can be changed under the adjustment of the steering roller 13.

[0042] Reference Figure 2 , Figure 6-Figure 10 A lithium battery 10 is fixedly installed on the upper surface of the control cabinet 1, and the lithium battery 10 is electrically connected to an electromagnet 17 through an electric wire. A limited track 12 is fixedly installed on one side of the control cabinet 1. The limited track 12 is provided with two grooves with T-shaped end faces. A mounting block matching therewith is slidably installed in the two grooves. A movable plate 26 is fixedly installed on the mounting block, and a magnet 25 is fixedly installed on the mounting block. An annular block is fixedly installed on one side of the control cabinet 1, and an electric push rod 11 is fixedly installed in the annular block. A connecting rod 24 is fixedly installed on the driving end of the electric push rod 11, and the electromagnet 17 is fixedly connected to the connecting rod 24. The straight line where the electromagnet 17 and the magnet 25 are located is parallel to the length direction of the limited track 12. The electromagnet 17 is energized by the lithium battery 10, so that the electromagnet 17 and the magnet 25 are attracted to each other, which can control the position of the mounting block and the movable plate 26 on the limited track 12 to prevent the mounting block from shaking.

[0043] A magnet 2 30 is fixedly mounted on one side of the mounting block, and a fixed ring plate ( Figure 8 As shown in ), an electromagnet 29 is fixedly installed in the fixed ring plate, and the electromagnet 29 is electrically connected to a lithium battery 28 through two cables. The lithium battery 10 and the lithium battery 28 can generate alternating current, and the current can be changed, so that the tension can be better adjusted (the tension sensor 4 can control the current size of the lithium battery 10 and the lithium battery 28 according to the tension), and the lithium battery 28 is fixedly installed on one side of the control cabinet 1. The electromagnet 29 is energized by the lithium battery 28, and the lithium battery 28 can change the direction of the current, so that the force between the electromagnet 29 and the magnet 2 30 changes, thereby driving the movable plate 26 to slide on the limit track 12 through the mounting block.

[0044] Since the movable plate 26 slides on the limiting track 12, the sliding will generate friction. At this time, the electromagnet 29 is energized through the lithium battery 28. The lithium battery 28 can change the direction of the current, so that the force between the electromagnet 29 and the magnet 2 30 changes. The movable plate 26 moves up, and the force between the electromagnet 29 and the magnet 2 30 is repulsive. The movable plate 26 moves down, and the force between the electromagnet 29 and the magnet 2 30 is attractive. In this way, the friction between the movable plate 26 and the limiting track 12 can be overcome, and the influence of the friction on the movement of the movable plate 26 is reduced, thereby improving the accuracy of tension adjustment.

[0045] The tension sensor 4 can sense the tension of spinning through the tension sensing roller 3. The tension sensor 4 is connected to an external controller, and the controller can control the operation of the lithium battery 10, the electric push rod 11 and the lithium battery 28 (the lithium battery 10 and the lithium battery 2 28 can judge the size of the released current according to the tension, thereby changing the size of the suction and repulsion forces, and the electric push rod 11 can judge the extension and shortening according to the tension).

[0046] The movable plate 26 is fixedly mounted with a movable block ( Figure 8 As shown, two connecting brackets 27 are rotatably mounted on the movable block, and a connecting ring 20 is rotatably mounted on the two connecting brackets 27. An adjusting rod 9 is fixedly mounted in the connecting ring 20, and a fixing sleeve 15 is fixedly mounted on one end of the adjusting rod 9. A fixing plate is fixedly mounted on the fixing sleeve 15, and a cross bar ( Fig.10 As shown in the figure, a damping bearing 21 is fixedly mounted on the cross bar, and pay-off rollers 16 are fixedly mounted on both ends of the cross bar. When the tension of the yarn is unstable and needs to be adjusted, the adjusting rod 9 will be driven to shake, thereby driving the movable plate 26 and the mounting block to slide on the limiting track 12.

[0047] Two winding methods can be used according to the tension of the blended yarn. Different spinning methods use different winding methods (the two winding methods correspond to the tension of spinning in two intervals respectively). When the tension is large, the yarn passes through the driving roller 5, the tension sensing roller 3, the tightening roller 6, the damping roller 14 close to the tightening roller 6 and the corresponding alignment roller 7 in sequence, and then passes through the top of the steering roller 13, between another alignment roller 7 and the corresponding damping roller 14, the straightening roller 8 and the pay-off roller 16 above the control cabinet 1, and connects it with the existing winding roller. , the blended yarn is wound up; when the tension of the blended yarn is small, the yarn is passed through the driving roller 5, the tension sensing roller 3, the tightening roller 6, the damping roller 14 close to the tightening roller 6 and the corresponding alignment roller 7 in sequence, and then passed between the two alignment rollers 7, the steering roller 13, the straightening roller 8 and the pay-off roller 16 close to the control cabinet 1 for winding (the friction between the rollers and the fibers will also affect the tension of the yarn. More rollers can increase the friction, which helps to stabilize the fiber transfer process and thus maintain appropriate tension. Therefore, two winding methods are used).

[0048] A bearing 18 is fixedly installed on one side of the control cabinet 1, and a mounting clip 19 is fixedly sleeved inside the bearing 18, and the adjusting rod 9 is fixedly installed in the mounting clip 19. An arc groove matching the adjusting rod 9 is provided in the mounting clip 19, which can better fix the adjusting rod 9. The mounting clip 19 is used to fix the adjusting rod 9 by bolts and nuts, which makes it easy to adjust the clamping position of the adjusting rod 9 on the mounting clip 19, thereby adjusting the tension during winding.

[0049] When the yarn shakes, the tension needs to be adjusted. The current of the lithium battery 10 can be controlled to discharge the electromagnet 17, so that the magnet 25 can be moved on the limit track 12, thereby realizing the first adjustment of the yarn tension. The extension length of the electric push rod 11 can also be controlled. When the current size remains unchanged, the magnetic force between the electromagnet 17 and the magnet 25 can be adjusted by adjusting the length of the electric push rod 11, thereby controlling the stability of the movable plate 26 and the adjusting rod 9. This is the second tension adjustment method. The two adjustment methods are used in combination to increase the range of tension adjustment.

[0050] The specific operation steps of the present invention are as follows:

[0051] The driving roller 5 is driven to rotate by the servo motor 22, and the wire coming out from one end of the pay-off roller 16 is connected to the winding roller on the existing winding device;

[0052] Double adjustment of the tension: As the winding progresses, the diameter of the yarn wound on the winding roller becomes larger and larger. At this time, the spinning winding speed becomes faster and faster. In order to stabilize the winding tension, it is necessary to adjust the tension of the yarn. When the yarn passes through the pay-off roller 16, due to the change in tension, the adjusting rod 9 will be driven to rotate around the bearing 18, and the electromagnet 17 will be energized through the lithium battery 10, so that the electromagnet 17 and the magnet 25 will attract each other, so that the rotation angle of the adjusting rod 9 can be automatically adjusted to achieve the reciprocating vibration of the adjusting rod 9, replacing the spring to adjust the tension and improve the accuracy of the tension adjustment; at the same time, the connecting rod 24 can be driven to move by the electric push rod 11 to change the distance between the electromagnet 17 and the magnet 25, so that the suction between the electromagnet 17 and the magnet 25 can be changed. This method is a way to change the suction. The suction can also be changed by adjusting the current through the lithium battery 10. The winding tension is double adjusted by two methods, the adjustment accuracy is finer, the tension change is more subtle, and the winding is more uniform;

[0053] The vibration generated during winding is adjusted: the vibration of the adjusting rod 9 will drive the movable plate 26 and the mounting block to slide on the limiting track 12 through the connecting ring 20 and the connecting bracket 27. When the adjusting rod 9 vibrates and drives the movable plate 26 to move upward on the limiting track 12, the lithium battery 28 is started at this time so that there is a repulsive force between the electromagnet 29 and the magnet 2 30. When the adjusting rod 9 vibrates and drives the movable plate 26 to move downward on the limiting track 12, the lithium battery 28 is started at this time so that there is a suction force between the electromagnet 29 and the magnet 2 30, which can reduce the friction of the mounting block sliding on the limiting track 12, thereby reducing the influence of the friction on the movement of the movable plate 26, thereby improving the accuracy of the tension adjustment, and reducing the vibration generated by the adjusting rod 9 through the suction and repulsive forces. As long as the adjusting rod 9 is stable, it means that the tension is stable.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
