Description

Technical Field

[0001] The utility model relates to the field of textiles, in particular to a magnetic tension wire adjusting device for a winding machine. Background Art

[0002] At present, textile equipment such as sewing machines and embroidery machines in the textile field need to be equipped with bobbins for winding wires for sewing and embroidery operations. The wire on the bobbin is wound by a winding machine. Specifically, the wire on the winding machine first passes through a wire adjuster, and then passes through a series of wire structures before being wound on the bobbin, wherein the wire adjuster is used to adjust the tightness of the wire wound on the bobbin. The wire adjuster on the winding machine is generally formed by a combination of a wire pressing piece, a spring and a wire pressing knob. The wire pressing piece presses the wire, and the wire pressing knob is manually rotated to adjust the pressing force of the spring on the wire pressing piece and the wire, thereby adjusting the tightness of the wire wound on the bobbin.

[0003] The thread adjuster currently used in the winding machine has the following disadvantages: the thread is pressed by the thread pressing piece, and the thread will be subjected to greater friction when passing through the thread adjuster. As a result, the thread is easily worn and damaged when passing through the thread adjuster, resulting in the problem of thread breakage during the winding process, and affecting the quality of the thread wound on the bobbin.

[0004] On the other hand, the tightness of the thread wound on the bobbin depends on the operator manually adjusting the thread pressing knob. However, manual adjustment of the thread pressing knob has the problem of poor adjustment accuracy of the pressing force of the thread pressing piece, and the pressing force of the thread pressing piece may be too large, resulting in thread breakage. Utility Model Content

[0005] The first purpose of the utility model is to provide a magnetic tension wire adjusting device for a winding machine, which can effectively solve the problem that the wire of the winding machine in the prior art is easily damaged by wear when passing through the wire adjuster, resulting in wire breakage during the winding process and affecting the quality of the wound wire.

[0006] The second purpose of the utility model is to provide a magnetic tension wire adjusting device for a winding machine which can conveniently and accurately adjust the tightness of the winding wire.

[0007] The technical solution of the utility model is:

[0008] A magnetic tension wire adjusting device for a winding machine, comprising:

[0009] A magnetic damper, the magnetic damper comprising a rotating shaft;

[0010] The adjusting wheel is fixed on the rotating shaft of the magnetic damper, and the wire of the winding machine passes through the adjusting wheel. After the wire of the winding machine passes through the adjusting wheel, it is wound on the bobbin. The tightness of the wire winding on the bobbin is adjusted by the magnetic damper. Specifically, the magnetic damper can accurately adjust the damping magnitude during the rotation of the rotating shaft, and then adjust the damping magnitude during the rotation of the adjusting wheel. Since the wire of the winding machine passes through the adjusting wheel and is wound on the bobbin, the greater the damping during the rotation of the adjusting wheel, the tighter the tightness of the wire winding on the bobbin; conversely, the looser the tightness of the wire winding on the bobbin; based on this, a magnetic tension wire adjusting device for a winding machine in this scheme can accurately adjust the tightness of the wire winding on the bobbin through a magnetic damper, which is beneficial to improving the quality of the wire winding on the bobbin, and effectively solves the problem of wire breakage due to poor adjustment accuracy of the pressing force of the wire pressing plate when manually adjusting the wire pressing knob, and excessive pressing force of the wire pressing plate. At the same time, since the wire of the winding machine is only wound around the wire adjusting wheel, the friction it encounters during the process of passing through the wire adjusting wheel is extremely small and it will not be worn or damaged. Therefore, it can effectively solve the problem that the wire of the winding machine in the prior art is easily worn and damaged during the process of passing through the wire adjusting device, which leads to the problem of wire breakage during the winding process and affects the quality of the wound wire.

[0011] Preferably, the number of turns of the wire of the winding machine on the wire adjustment wheel is greater than or equal to 1. In this way, it is ensured that the magnetic damper can accurately adjust the damping during the rotation of the wire adjustment wheel, and then accurately adjust the tightness of the wire winding on the bobbin.

[0012] Preferably, the number of turns of the wire winding machine on the wire adjustment wheel is 1-3. It is not necessary to wind too many turns of the wire on the wire adjustment wheel. Too many turns of winding are not convenient for actual operation and will reduce the operating efficiency.

[0013] Preferably, the line adjusting wheel is provided with a winding groove, so that the line will be wound in the winding groove, thereby limiting the position of the line wound on the line adjusting wheel.

[0014] Preferably, the winding groove is V-shaped. In this way, the wire wound in the winding groove will gather at the bottom of the winding groove, based on which the length of the wire released by each rotation of the adjusting wheel will remain consistent, which is conducive to ensuring the consistency of the tightness of the winding on the bobbin.

[0015] Preferably, the magnetic damper is fixed on the frame of the winding machine.

[0016] Preferably, the frame includes a mounting plate, the mounting plate is provided with an axis through hole, the magnetic damper is mounted on the mounting plate, the rotating shaft passes through the axis through hole, and the line adjustment wheel and the magnetic damper are located on opposite sides of the mounting plate. After the line on the winding machine passes through the line adjustment wheel, it generally passes through other wire structures (such as guide wheels and wire sleeves), so the present solution places the line adjustment wheel and the magnetic damper on opposite sides of the mounting plate, so that the layout of the line adjustment wheel and other wire structures on the winding machine can be facilitated, and the line track of the winding machine can be optimized.

[0017] Preferably, it also includes an upper guide wheel and a conductor sleeve, wherein the wire adjusting wheel, the upper guide wheel and the conductor sleeve are arranged in sequence from top to bottom, and the wire of the winding machine passes around the upper guide wheel and through the conductor sleeve.

[0018] Preferably, it also includes a lower guide wheel, which is located below the wire sleeve and the wire of the winding machine passes around the lower guide wheel.

[0019] Preferably, the magnetic damper is fixed to the frame of the winding machine by bolts or rivets, so that the installation, removal and replacement of the magnetic damper are convenient.

[0020] The beneficial effects of the utility model are:

[0021] Firstly, it can effectively solve the problem that the wire of the winding machine in the prior art is easily damaged by wear when passing through the wire adjuster, which leads to the problem of wire breakage during the winding process and affects the quality of the wound wire.

[0022] Secondly, it is convenient to accurately adjust the tightness of the winding, which is beneficial to improving the winding quality of the bobbin. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Specific embodiment 1, as Figure 1 , Figure 2 , Figure 3 As shown, a magnetic tension wire adjustment device for a winding machine includes a magnetic damper 1 and a wire adjustment wheel 2. The magnetic damper 1 in this embodiment is a magnetic damper 1 with scale lines. The magnetic damper 1 can adjust the magnitude of the damping force by a knob. The magnetic damper 1 includes a rotating shaft.

[0035] The line-adjusting wheel 2 is fixed on the rotating shaft of the magnetic damper 1 , and the line 3 of the winding machine passes around the line-adjusting wheel 2 .

[0036] The wire 3 of the winding machine is wound around the adjusting wheel 2 and then wound on the bobbin. The tightness of the winding on the bobbin is adjusted by the magnetic damper 1. Specifically, the magnetic damper 1 accurately adjusts the damping amount of the rotating shaft during the rotation process through the knob, and then adjusts the damping amount of the adjusting wheel 2 during the rotation process. Since the wire of the winding machine is wound around the bobbin after passing around the adjusting wheel 2, the greater the damping during the rotation of the adjusting wheel 2, the tighter the tightness of the winding on the bobbin; conversely, the smaller the damping during the rotation of the adjusting wheel 2, the tighter the tightness of the winding on the bobbin, and the looser the tightness of the winding on the bobbin. Based on this, a magnetic tension line adjusting device for a winding machine of the present embodiment can accurately adjust the tightness of the winding of the line on the bobbin core through the magnetic damper 1, which is beneficial to improving the winding quality of the line on the bobbin core; at the same time, since the damping of the line adjusting wheel 2 during rotation can be accurately adjusted, the problem of line breakage caused by excessive adjustment of the damping of the magnetic damper 1 due to poor manual precision can be avoided (that is, the problem of line breakage caused by poor adjustment precision of the pressing force of the pressing piece of the manual adjustment of the pressing knob can be effectively solved).

[0037] On the other hand, since the wire of the winding machine is only wound around the adjusting wheel 2, the friction force it encounters during the process of passing through the adjusting wheel 2 is extremely small and it will not be worn or damaged. This is beneficial to ensuring the quality of the wire wound on the bobbin core and effectively solves the problem that the wire of the winding machine in the prior art is easily worn and damaged during the process of passing through the adjusting wheel, which leads to the problem of wire breakage during the winding process and affects the quality of the wound wire.

[0038] Specific embodiment 2, as Figure 1 , Figure 2 , Figure 3As shown, a magnetic tension wire adjustment device for a winding machine includes a magnetic damper 1 and a wire adjustment wheel 2. The magnetic damper 1 in this embodiment is a magnetic damper 1 with scale lines. The magnetic damper 1 can adjust the magnitude of the damping force by a knob. The magnetic damper 1 includes a rotating shaft.

[0039] The adjusting wheel 2 is fixed on the rotating shaft of the magnetic damper 1, and the wire 3 of the winding machine is wound around the adjusting wheel 2. The number of turns of the wire 3 of the winding machine on the adjusting wheel 2 is greater than or equal to 1 turn. For example, the number of turns of the wire 3 of the winding machine on the adjusting wheel 2 is 1 turn, or the number of turns of the wire 3 of the winding machine on the adjusting wheel 2 is 2 turns, or the number of turns of the wire 3 of the winding machine on the adjusting wheel 2 is 3 turns. In this embodiment, the number of turns of the wire 3 of the winding machine on the adjusting wheel 2 is 1 turn.

[0040] The wire 3 of the winding machine is wound around the adjusting wheel 2 and then wound on the bobbin. The tightness of the winding on the bobbin is adjusted by the magnetic damper 1. Specifically, the magnetic damper 1 accurately adjusts the damping amount of the rotating shaft during the rotation process through the knob, and then adjusts the damping amount of the adjusting wheel 2 during the rotation process. Since the wire of the winding machine is wound around the bobbin after passing around the adjusting wheel 2, the greater the damping during the rotation of the adjusting wheel 2, the tighter the tightness of the winding on the bobbin; conversely, the smaller the damping during the rotation of the adjusting wheel 2, the tighter the tightness of the winding on the bobbin, and the looser the tightness of the winding on the bobbin. Based on this, a magnetic tension line adjusting device for a winding machine of the present embodiment can accurately adjust the tightness of the winding of the line on the bobbin core through the magnetic damper 1, which is beneficial to improving the winding quality of the line on the bobbin core; at the same time, since the damping of the line adjusting wheel 2 during rotation can be accurately adjusted, the problem of line breakage caused by excessive adjustment of the damping of the magnetic damper 1 due to poor manual precision can be avoided (that is, the problem of line breakage caused by poor adjustment precision of the pressing force of the pressing piece of the manual adjustment of the pressing knob can be effectively solved).

[0041] On the other hand, since the wire of the winding machine is only wound around the adjusting wheel 2, the friction force it encounters during the process of passing through the adjusting wheel 2 is extremely small and it will not be worn or damaged. This is beneficial to ensuring the quality of the wire wound on the bobbin core and effectively solves the problem that the wire of the winding machine in the prior art is easily worn and damaged during the process of passing through the adjusting wheel, which leads to the problem of wire breakage during the winding process and affects the quality of the wound wire.

[0042] Specific embodiment three, as Figure 1 , Figure 2 , Figure 3As shown, a magnetic tension wire adjustment device for a winding machine includes a magnetic damper 1 and a wire adjustment wheel 2. The magnetic damper 1 in this embodiment is a magnetic damper 1 with scale lines. The magnetic damper 1 can adjust the magnitude of the damping force by a knob. The magnetic damper 1 includes a rotating shaft.

[0043] The adjusting wheel 2 is provided with a winding groove 2.1. The adjusting wheel 2 is fixed on the rotating shaft of the magnetic damper 1, and the line 3 of the winding machine is wound around the adjusting wheel 2. Specifically, the line 3 of the winding machine is wound around the winding groove 2.1 of the adjusting wheel 2. The number of turns of the line 3 of the winding machine on the adjusting wheel 2 is greater than or equal to 1 turn. For example, the number of turns of the line 3 of the winding machine on the adjusting wheel 2 is 1 turn, or the number of turns of the line 3 of the winding machine on the adjusting wheel 2 is 2 turns, or the number of turns of the line 3 of the winding machine on the adjusting wheel 2 is 3 turns. In this embodiment, the number of turns of the line 3 of the winding machine on the adjusting wheel 2 is 1 turn.

[0044] The wire 3 of the winding machine is wound around the adjusting wheel 2 and then wound on the bobbin. The tightness of the winding on the bobbin is adjusted by the magnetic damper 1. Specifically, the magnetic damper 1 accurately adjusts the damping amount of the rotating shaft during the rotation process through the knob, and then adjusts the damping amount of the adjusting wheel 2 during the rotation process. Since the wire of the winding machine is wound around the bobbin after passing around the adjusting wheel 2, the greater the damping during the rotation of the adjusting wheel 2, the tighter the tightness of the winding on the bobbin; conversely, the smaller the damping during the rotation of the adjusting wheel 2, the tighter the tightness of the winding on the bobbin, and the looser the tightness of the winding on the bobbin. Based on this, a magnetic tension line adjusting device for a winding machine of the present embodiment can accurately adjust the tightness of the winding of the line on the bobbin core through the magnetic damper 1, which is beneficial to improving the winding quality of the line on the bobbin core; at the same time, since the damping of the line adjusting wheel 2 during rotation can be accurately adjusted, the problem of line breakage caused by excessive adjustment of the damping of the magnetic damper 1 due to poor manual precision can be avoided (that is, the problem of line breakage caused by poor adjustment precision of the pressing force of the pressing piece of the manual adjustment of the pressing knob can be effectively solved).

[0045] On the other hand, since the wire of the winding machine is only wound around the adjusting wheel 2, the friction force it encounters during the process of passing through the adjusting wheel 2 is extremely small and it will not be worn or damaged. This is beneficial to ensuring the quality of the wire wound on the bobbin core and effectively solves the problem that the wire of the winding machine in the prior art is easily worn and damaged during the process of passing through the adjusting wheel, which leads to the problem of wire breakage during the winding process and affects the quality of the wound wire.

[0046] In this embodiment, the winding groove 2.1 is V-shaped (i.e., the cross section of the winding groove 2.1 is V-shaped). In this way, the wire wound in the winding groove 2.1 will gather at the bottom of the winding groove 2.1, so that the length of each circle of wire wound on the winding groove 2.1 is almost the same. Based on this, the length of the wire released by each rotation of the adjusting wheel 2 remains consistent, which is conducive to ensuring the consistency of the tightness of the winding on the bobbin core and improving the quality of the winding on the bobbin core.

[0047] Of course, it should be noted that the cross section of the winding groove 2.1 may also be in other shapes, for example, the cross section of the winding groove 2.1 may be in a U-shape, a trapezoid, a rectangle, an arc, etc.

[0048] Specific embodiment four, as Figure 1 , Figure 2 , Figure 3 As shown, a magnetic tension wire adjustment device for a winding machine includes a magnetic damper 1 and a wire adjustment wheel 2. The magnetic damper 1 in this embodiment is a magnetic damper 1 with scale lines. The magnetic damper 1 can adjust the magnitude of the damping force by a knob. The magnetic damper 1 includes a rotating shaft. The magnetic damper 1 is fixed to the frame of the winding machine. In this embodiment, the magnetic damper 1 is fixed to the frame of the winding machine by bolts or rivets. In this way, the installation, disassembly and replacement of the magnetic damper 1 are convenient. Of course, it should be noted that the magnetic damper 1 can also be fixed to the frame of the winding machine by other means, such as fixing the magnetic damper 1 to the frame of the winding machine by welding or bonding.

[0049] The adjusting wheel 2 is provided with a winding groove 2.1. The adjusting wheel 2 is fixed on the rotating shaft of the magnetic damper 1, and the line 3 of the winding machine is wound around the adjusting wheel 2. Specifically, the line 3 of the winding machine is wound around the winding groove 2.1 of the adjusting wheel 2. The number of turns of the line 3 of the winding machine on the adjusting wheel 2 is greater than or equal to 1 turn. For example, the number of turns of the line 3 of the winding machine on the adjusting wheel 2 is 1 turn, or the number of turns of the line 3 of the winding machine on the adjusting wheel 2 is 2 turns, or the number of turns of the line 3 of the winding machine on the adjusting wheel 2 is 3 turns. In this embodiment, the number of turns of the line 3 of the winding machine on the adjusting wheel 2 is 1 turn.

[0050] The wire 3 of the winding machine is wound around the adjusting wheel 2 and then wound on the bobbin. The tightness of the winding on the bobbin is adjusted by the magnetic damper 1. Specifically, the magnetic damper 1 accurately adjusts the damping amount of the rotating shaft during the rotation process through the knob, and then adjusts the damping amount of the adjusting wheel 2 during the rotation process. Since the wire of the winding machine is wound around the bobbin after passing around the adjusting wheel 2, the greater the damping during the rotation of the adjusting wheel 2, the tighter the tightness of the winding on the bobbin; conversely, the smaller the damping during the rotation of the adjusting wheel 2, the tighter the tightness of the winding on the bobbin, and the looser the tightness of the winding on the bobbin. Based on this, a magnetic tension line adjusting device for a winding machine of the present embodiment can accurately adjust the tightness of the winding of the line on the bobbin core through the magnetic damper 1, which is beneficial to improving the winding quality of the line on the bobbin core; at the same time, since the damping of the line adjusting wheel 2 during rotation can be accurately adjusted, the problem of line breakage caused by excessive adjustment of the damping of the magnetic damper 1 due to poor manual precision can be avoided (that is, the problem of line breakage caused by poor adjustment precision of the pressing force of the pressing piece of the manual adjustment of the pressing knob can be effectively solved).

[0051] On the other hand, since the wire of the winding machine is only wound around the adjusting wheel 2, the friction force it encounters during the process of passing through the adjusting wheel 2 is extremely small and it will not be worn or damaged. This is beneficial to ensuring the quality of the wire wound on the bobbin core and effectively solves the problem that the wire of the winding machine in the prior art is easily worn and damaged during the process of passing through the adjusting wheel, which leads to the problem of wire breakage during the winding process and affects the quality of the wound wire.

[0052] Specifically, a magnetic tension wire adjustment device for a winding machine also includes an upper guide wheel 5, a wire sleeve 6 and a lower guide wheel 7. The wire adjustment wheel 2, the upper guide wheel 5, the wire sleeve 6 and the lower guide wheel 7 are arranged in sequence from top to bottom. The wire 3 of the winding machine passes around the upper guide wheel 5, the wire 3 of the winding machine passes through the wire sleeve 6, and the wire 3 of the winding machine passes around the lower guide wheel 7. Specifically, the wire 3 of the winding machine first passes around the wire adjustment wheel 2, then around the upper guide wheel 5, then through the wire sleeve 6, then around the lower guide wheel 7, and then wound on the bobbin.

[0053] The frame includes a mounting plate 4. In the present embodiment, the mounting plate 4 is vertically arranged. The mounting plate 4 is provided with an axis through hole. The magnetic damper 1 is mounted on the mounting plate 4. The rotating shaft passes through the axis through hole. The rotating shaft is horizontally arranged. The line adjusting wheel 2 and the magnetic damper 1 are located on opposite sides of the mounting plate 4. After the line adjusting wheel 2 is passed through the line adjusting wheel 2, the line on the winding machine generally needs to pass through other conductor structures (such as guide wheels and conductor sleeves 6). Therefore, in the present scheme, the line adjusting wheel 2 and the magnetic damper 1 are located on opposite sides of the mounting plate 4. In this way, the layout of the line adjusting wheel 2 and other conductor structures on the winding machine can be facilitated, and the line path trajectory of the winding machine can be optimized.

[0054] In this embodiment, the upper guide wheel 5, the conductor sleeve 6 and the lower guide wheel 7 are all arranged on the mounting plate 4, and the line adjusting wheel 2, the upper guide wheel 5, the conductor sleeve 6 and the lower guide wheel 7 are provided once on the mounting plate 4.

[0055] In this embodiment, the winding groove 2.1 is V-shaped. In this way, the wire wound in the winding groove 2.1 will gather at the bottom of the winding groove 2.1, so that the length of each circle of wire wound on the winding groove 2.1 is almost the same. Based on this, the length of the wire released by each rotation of the adjusting wheel 2 remains consistent, which is conducive to ensuring the consistency of the tightness of the winding on the bobbin core and improving the quality of the winding on the bobbin core.

[0056] The above description is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention.
