Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, and in particular to a thread blowing and thread-tying device. Background Technology

[0002] Industrial sewing machines are designed for the large-scale production of sewn workpieces in factories and other industrial sectors. The rotary hook of an industrial sewing machine contains a bobbin, which consists of a bobbin case and a bobbin with thread wound around it. Because the bobbin has a limited thread capacity, sewing must stop when the thread in the bobbin is exhausted to replace the fully wound bobbin. Current automatic winding machines first press the thread end onto the end face of the bobbin, then the bobbin rotates, winding 5 to 6 turns of thread to ensure the thread winds with the rotation of the bobbin. However, this automatic winding machine suffers from numerous winding actions and low efficiency. An improved automatic winding machine uses a blower mechanism to directly blow the thread into the bobbin case, achieving thread winding with the rotation of the bobbin. In practical applications, it has been found that because the thread end is relatively stiff, it is not easy to curl and wind onto the bobbin. Therefore, it is necessary to design a blower and thread-winding device to soften the thread end. Utility Model Content

[0003] This invention provides a wire blowing and wire forming device to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] The thread-punching component includes: a thread-punching drive wheel, a thread-punching drive driver, a thread-punching driven wheel, and a thread-punching driven driver. The blower gun rotation driver drives the blower gun to rotate until the outlet of the blower gun is aligned between the thread-punching driven wheel and the thread-punching drive wheel. The blower gun blows the thread end into the space between the thread-punching driven wheel and the thread-punching drive wheel. The thread-punching driven driver drives the thread-punching driven wheel to reciprocate along the line connecting the rotation centers of the thread-punching driven wheel and the thread-punching drive wheel. The thread-punching driven wheel and the thread-punching drive wheel continuously contact and separate. The thread-punching drive driver drives the thread-punching drive wheel to rotate. When the thread-punching driven wheel and the thread-punching drive wheel contact each other, the thread-punching drive wheel drives the thread-punching driven wheel to rotate in the opposite direction, thereby making the thread-punching driven wheel and the thread-punching drive wheel poke the thread end.

[0011] Preferably, the wire-punching component further includes a wire-punching gun limiting component for limiting the rotational position of the wire-punching gun. The wire-punching gun limiting component includes a wire-punching gun limiter with a limiting plane. The plane of the limiting plane passes through the space between the wire-punching driven wheel and the wire-punching driving wheel. The wire-punching gun rotates and abuts against the limiting plane to align between the wire-punching driven wheel and the wire-punching driving wheel.

[0012] Preferably, it also includes a mounting plate, on which the blow gun component and the wire-punching component are both mounted.

[0013] Preferably, the wire-punching drive wheel, the wire-punching driven wheel, and the blow gun are located on the same side of the mounting plate, while the wire-punching drive driver, the wire-punching driven driver, and the blow gun rotary driver are mounted on the other side of the mounting plate. The wire-punching component also includes a first wire-punching shaft and a second wire-punching shaft. A first elongated hole is provided on the mounting plate along the line connecting the rotation centers of the wire-punching driven wheel and the wire-punching drive wheel. One end of the first wire-punching shaft is connected to the wire-punching drive driver, and the other end passes through the first elongated hole and is connected to the wire-punching drive wheel. One end of the second wire-punching shaft is connected to the wire-punching driven driver, and the other end passes through the first elongated hole and is connected to the wire-punching driven wheel. The output shaft of the blow gun rotary driver passes through the mounting plate and is connected to the blow gun.

[0014] Preferably, the first elongated hole is countersunk at the edge facing the wire-casting drive wheel, and the end faces of the wire-casting drive wheel and the wire-casting driven wheel facing the wire-casting drive driver are located between the mounting plate surface on the side of the mounting plate away from the wire-casting drive driver and the first countersunk plane for countersunk processing.

[0015] Preferably, the mounting plate is vertically arranged, and the rotation axes of the wire-casting drive wheel and the wire-casting driven wheel are perpendicular to the mounting plate.

[0016] Beneficial effects:

[0017] The thread blowing and thread-applying device disclosed in this application delivers the thread end of the sewing thread to the thread-applying driven wheel and the thread-applying driving wheel through a thread-blowering gun; the thread-applying driven wheel is driven by a thread-applying driven driver to reciprocate and continuously contact and separate from the thread-applying driving wheel; finally, the thread-applying driven wheel contacts the thread-applying driving wheel, and then the thread-applying driving wheel rotates, thereby the thread-applying driven wheel and the thread-applying driving wheel fluff the thread end, making the thread end soft and the strands separate, which is conducive to the thread end curling and winding around the bobbin.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] A wire blowing and wire forming device, combined with Figures 1-9As shown, the device includes a blower gun assembly 21 for blowing out the sewing thread and a thread-reducing assembly 22 for roughening the thread ends blown out by the blower gun assembly 21. The blower gun assembly 21 includes a blower gun 211 for blowing out the sewing thread and a blower gun rotation driver 212 for driving the blower gun 211 to rotate. The thread-reducing assembly 22 includes a thread-reducing drive wheel 221, a thread-reducing drive driver 222, a thread-reducing driven wheel 223, and a thread-reducing driven driver 224. The blower gun rotation driver 212 drives the blower gun 211 to rotate until the thread outlet of the blower gun 211 is aligned between the thread-reducing driven wheel 223 and the thread-reducing drive wheel 221. The thread end is blown into the space between the driven thread-beating wheel 223 and the driving thread-beating wheel 221; the driven thread-beating driver 224 drives the driven thread-beating wheel 223 to reciprocate along the line connecting the rotation centers of the driven thread-beating wheel 223 and the driving thread-beating wheel 221, and the driven thread-beating wheel 223 and the driving thread-beating wheel 221 continuously contact and separate; the driving thread-beating driver 222 drives the driving thread-beating wheel 221 to rotate; when the driven thread-beating wheel 223 and the driving thread-beating wheel 221 contact, the driving thread-beating wheel 221 drives the driven thread-beating wheel 223 to rotate in opposite directions, thereby the driven thread-beating wheel 223 and the driving thread-beating wheel 221 beat the thread end. This application uses a blower gun rotary driver 212 to drive the blower gun 211 to rotate, so that the blower gun 211 can rotate until its outlet is aligned between the driven wheel 223 and the driving wheel 221. The blower gun 211 uses airflow to blow the thread end between the driven wheel 223 and the driving wheel 221. The driven wheel 223 is driven to reciprocate by the driven driver 224, causing the driven wheel 223 and the driving wheel 221 to continuously contact and separate, which continuously strikes the thread end, making the strands of the thread end braided together loose and soft. Then, the thread-beating drive 222 drives the thread-beating drive wheel 221 to rotate. When the two come into contact, the thread-beating drive wheel 221 drives the thread-beating driven wheel 223 to rotate in opposite directions, thereby roughening a section of the thread starting from the thread end, making the thread end soft and separating the strands. This makes it easier for the blow gun 211 to blow the thread end into the bobbin case, and the thread end curls and wraps around the bobbin as the bobbin rotates.

[0033] Specifically, the blow gun 211 includes a main body 2111 and a barrel 2112. The main body 2111 has a first channel 2113 and a second channel 2114. The first channel 2113 is connected to a blow gun inlet 2115 and a blow gun outlet 2116 at its two ends, respectively. The second channel 2114 is connected to a blow gun air inlet 2117 at one end and to the middle of the first channel 2113 at the other end. A barrel fixing structure is provided at the blow gun outlet 2116 of the main body 2111 to fix the barrel 2112, so that the barrel 2112 is connected to the blow gun outlet 2116. In this embodiment, the barrel fixing structure is detachable. A slit groove 2118 is formed at the wire outlet 2116 of the gun body 2111 along the diameter direction of the wire outlet 2116. The slit groove 2118 extends through both sides of the gun body 2111 and extends a certain distance along the center line of the first channel 2113. Along the center line of the first channel 2113, the end of the slit groove 2118 away from the wire outlet 2116 is machined with an arc-shaped surface to release stress. The gun barrel 2112 is inserted from the wire outlet 2116 into the first channel 2113. By tightening the two gun barrel clamping screws 2119, the slit groove 2118 is reduced, thereby clamping the gun body 2111 with the gun barrel 2112. It is understood that the gun barrel fixing structure can also adopt a threaded connection or welding fixing method. The air inlet 2117 of the blow gun is connected to the air supply pipe of the blow gun. The gas enters the middle of the first channel 2113 through the second channel 2114 and is blown out from the outlet 2116 of the blow gun, thereby generating negative pressure at the front of the first channel 2113. After the thread enters the first channel 2113 through the inlet 2115 of the blow gun, it is first driven forward by the negative pressure and then driven forward by the airflow, passing through the first channel 2113 and the outlet 2116 of the blow gun in sequence and entering the barrel 2112 to be blown out.

[0034] Specifically, the gun body 2111 has a blow gun rotating shaft mounting hole. One end of the blow gun rotating shaft is fixed in the blow gun rotating shaft mounting hole by two set screws, and the other end is coaxially connected to the blow gun rotating driver 212.

[0035] Preferably, both the thread-beating drive wheel 221 and the thread-beating driven wheel 223 are gears. After the thread-beating drive wheel 221 and the thread-beating driven wheel 223 mesh, they clamp the thread end. The meshing and rotation of the teeth better roughen the thread and soften the thread end.

[0036] Preferably, the thread-attaching driven actuator 224 is a cylinder, which has a simple operation and high reliability. The thread-attaching driven actuator 224 drives the thread-attaching driven wheel 223 to move closer to and away from the thread-attaching driven wheel 221. When the thread-attaching driven actuator 224 drives the thread-attaching driven wheel 223 away from the thread-attaching driven wheel 221, a certain gap is left between the thread-attaching driven wheel 223 and the thread-attaching driven wheel 221, allowing the thread end to be blown into the gap; then the thread-attaching driven actuator 224 drives the thread-attaching driven wheel 223 to move closer to the thread-attaching driven wheel 221 for engagement, thereby clamping the thread end, and then the thread-attaching driven actuator 222 drives the thread-attaching driven wheel 221 to rotate. First, the thread-attaching driven wheel 223 is driven by the cylinder to move linearly, and then the thread-attaching driven actuator 222 drives the thread-attaching driven wheel 221 to rotate, which ensures that the thread end is first subjected to impact and then crushed by the teeth, so that the thread end can be better frayed.

[0037] Specifically, the wire-beating active driver 222 uses a stepper motor, which drives the wire-beating active wheel 221 to rotate. The blow gun rotation driver 212 uses a geared motor, which drives the blow gun 211 to rotate.

[0038] Preferably, the wire-punching component 22 further includes a blow-wire gun origin sensor 227 for calibrating the origin position of the blow-wire gun 211, which is used to calibrate the reference position of the blow-wire gun 211 in order to accurately control the rotation angle of the blow-wire gun 211.

[0039] Preferably, the wire-punching component 22 further includes a wire-punching gun limiting component 228 for limiting the rotational position of the wire-punching gun 211. The wire-punching gun limiting component 228 includes a wire-punching gun limiter 2281, which has a limiting plane 2282. The plane of the limiting plane 2282 passes through the area between the wire-punching driven wheel 223 and the wire-punching driving wheel 221. The wire-punching gun 211 rotates and abuts against the limiting plane 2282 to align between the wire-punching driven wheel 223 and the wire-punching driving wheel 221.

[0040] Preferably, it also includes a mounting plate 8, on which the blow gun component 21 and the wire-punching component 22 are both mounted.

[0041] Preferably, the wire-punching drive wheel 221, the wire-punching driven wheel 223, and the blow gun 211 are located on the same side of the mounting plate 8, i.e., the front side of the mounting plate 8. The wire-punching drive driver 222, the wire-punching driven driver 224, and the blow gun rotary driver 212 are mounted on the other side of the mounting plate 8, i.e., the back side of the mounting plate 8. The wire-punching component 22 also includes a first wire-punching shaft 225 and a second wire-punching shaft 226. The mounting plate 8 has a first elongated hole 84 along the line connecting the rotation centers of the wire-punching driven wheel 223 and the wire-punching drive wheel 221. One end of the first wire-punching shaft 225 is connected to the wire-punching drive driver 222, and the other end passes through the first elongated hole 84 and is connected to the wire-punching drive wheel 221. One end of the second wire-punching shaft 226 is connected to the wire-punching driven driver 224, and the other end passes through the first elongated hole 84 and is connected to the wire-punching driven wheel 223. The output shaft of the blow gun rotary driver 212 passes through the mounting plate 8 and is connected to the blow gun 211. This arrangement makes the structure on the punching side simpler, which is beneficial for structural layout, observation of the working process, and later maintenance.

[0042] Specifically, the driven wire bonding driver 224 is fixed to the mounting plate 8 by a first set of fixing screws, the active wire bonding driver 222 is mounted on the active wire bonding driver mounting base 2221 by a second set of fixing screws, and the active wire bonding driver mounting base 2221 is fixed to the mounting plate 8 by a third set of fixing screws. The output end of the active wire bonding driver 222 passes through the clearance cavity of the active wire bonding driver mounting base 2221 and is connected to the first wire bonding shaft 225. The second wire bonding shaft 226 is threadedly connected to the push plate of the driven wire bonding driver 224. The push plate of the driven wire bonding driver 224 can enter the clearance cavity of the active wire bonding driver mounting base 2221, allowing the first wire bonding shaft 225 and the second wire bonding shaft 226 to approach each other. The blow gun rotary driver 212 is mounted on the blow gun rotary driver mounting base 2121 by a fourth set of fixing screws, and the blow gun rotary driver mounting base 2121 is fixed to the mounting plate 8 by a fifth set of fixing screws.

[0043] Specifically, the blow gun origin sensor 227 uses a proximity switch to generate an electrical signal when the blow gun 211 rotates to the origin position, which is used for controller position calibration. The blow gun origin sensor 227 is mounted on the blow gun origin sensor mounting base 2271. The fixed end of the blow gun origin sensor mounting base 2271 is fixed to the back side of the mounting plate 8 by a sixth set of fixing screws, and the mounting end is fixed to the blow gun origin sensor 227 by a seventh set of fixing screws. The mounting plate 8 has an origin sensor clearance hole, and the mounting end of the blow gun origin sensor mounting base 2271 passes through the origin sensor clearance hole to the front side of the mounting plate 8, so that the blow gun origin sensor 227 can generate a signal when the gun barrel 2112 rotates. In this embodiment, both the fixed end and the mounting end of the blow gun origin sensor mounting base 2271 have a second elongated hole for position adjustment during fixing.

[0044] Specifically, the blow gun limiting component 228 also includes a blow gun limiter mounting base 2283, which is L-shaped and includes a vertical part and a horizontal part. The vertical part is mounted on the front side of the mounting plate 8 by an eighth set of fixing screws, and the blow gun limiter 2281 is fixed to the upper surface of the horizontal part of the blow gun limiter mounting base 2283 by a ninth set of fixing bolts. Both the vertical and horizontal parts of the blow gun limiter mounting base 2283 have a third elongated hole for position adjustment during fixing.

[0045] Specifically, the blow gun limiter 2281 is made of a section of C-shaped channel steel, with the bottom of the C-shaped channel steel serving as the limiting plane 2282. The blow gun 211 is screwed into the slot of the C-shaped channel steel, and the barrel 2112 of the blow gun 211 abuts against the limiting plane 2282 to achieve positioning.

[0046] Preferably, the first elongated hole 84 is countersunk on the edge facing the wire-laying drive wheel 221. The end faces of the wire-laying drive wheel 221 and the wire-laying driven wheel 223 facing the wire-laying drive driver 222 are located between the mounting plate surface 83 on the side of the mounting plate 8 away from the wire-laying drive driver 222 and the first countersunk surface 85 where the countersunk is machined. If the gear faces the mounting plate surface 83 directly, a gap will be generated between the end of the gear and the mounting plate surface 83, and the wire end can easily fall into the gap and get stuck. The structure of this application can avoid this problem and ensure smooth wire collection.

[0047] Preferably, the mounting plate 8 is vertically arranged, and the rotation axes of the wire-tapping drive wheel 221 and the wire-tapping driven wheel 223 are perpendicular to the mounting plate 8, which facilitates the wire end to rest on the wire-tapping drive wheel 221 under the action of gravity. In this embodiment, the line connecting the rotation axes of the wire-tapping drive wheel 221 and the wire-tapping driven wheel 223 is vertically arranged, and the wire-tapping driven wheel 223 is located above the wire-tapping drive wheel 221, so that the wire end will not move up and down with the reciprocating motion of the wire-tapping driven wheel 223.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
