Detailed Description

The invention is further described below with reference to specific examples.

[ embodiment one ]

The embodiment is intended to provide a template machine capable of realizing three-dimensional sewing, and in the embodiment, the template machine can realize the sewing of the three-dimensional pattern without carving the shape of the pattern on the clothing template in advance, and the three-dimensional sewing can be realized for the pattern only by predefining the horizontal plane trend of the three-dimensional pattern.

The conventional sewing according to the pre-designed direction is a common function of the template machine, so one effect of the template machine according to the embodiment is that the template machine can be used without separately manufacturing templates for each pattern as in the prior art, and the template machine can be used as long as the template machine has the sewing function according to the set path, without separately designing the templates for a certain pattern, thereby realizing more convenient use experience and more efficient production efficiency.

It should be noted that, the stereo sewing described in this embodiment refers to, as shown in fig. 8, fig. 8 is a schematic cross-sectional view of the cloth 7 after being matched with the stereo medium 8. As can be seen from fig. 8, the condition after sewing is the mating condition with the cloth 7 up and the stereoscopic medium 8 down. The bottom line and the upper line on the existing template machine are matched to be wound between the three-dimensional medium 8 and the cloth in a reciprocating mode, so that the relative positions of the three-dimensional medium 8 and the cloth are fixed, and finally, the shape of the upper surface bulge is also called on the front surface of the cloth as shown in fig. 8, so that a three-dimensional sewing pattern is formed.

Next, the principle of implementation will be specifically described, and as shown in fig. 1, fig. 1 is a perspective view of a plate molding machine according to an embodiment. As can be seen from fig. 1, the template machine according to the present embodiment performs a sewing operation by moving the template in a basic operation mode; the basic components include:

a template driving device 1 for driving the template to move; it has at least the frame 11, the mesa 12 located in the upper side of frame 11 and used for placing the template and driving mechanism used for driving the template to move;

the machine head sewing device is provided with at least an upper thread sewing mechanism 2 and a lower thread sewing mechanism 3, and the upper thread sewing mechanism 2 and the lower thread sewing mechanism 3 are matched to form a lock stitch and sew materials;

that is, in the present embodiment, the operation mode of the template machine is such that the head sewing device is relatively stationary, corresponding to changing the position of the needle thread sewing mechanism 2 penetrating the template by moving the template. The upper thread sewing mechanism 2 described in this example refers to a combination of a series of components for guiding the connection of the upper thread and the lower thread sewing mechanism 3, including the casing 23, and the main shaft, the take-up lever, the needle bar 211, etc. in the casing 23. The bottom thread sewing mechanism 3 mainly comprises a rotating shuttle, a tooth frame and other parts.

Thus, in this embodiment, the combined action of the upper thread sewing mechanism 2 and the lower thread sewing mechanism 3 forms the basic function of the existing template machine to form stitches to complete sewing. It should be further noted that the mesa 12 shown in fig. 1 is only a part of an actual mesa 12, and in actual use, the mesa 12 may be sized accordingly according to process requirements.

Referring again to fig. 2, fig. 2 is a partially enlarged view of a portion a in fig. 1, and it can be seen from fig. 1 and 2 that the head sewing device further has at least a housing 23, and that the upper thread sewing mechanism 2 is disposed at one end of the housing 23. The upper end of the upper thread sewing mechanism 2 is provided with a reversing device 5 which can be used for driving the upper thread sewing mechanism 2 to move up and down and drive the upper thread sewing mechanism 2 to rotate. The reversing device 5 in this embodiment has the effect of making the head sewing device run perpendicular to the direction of travel of the cloth. The reversing device 5 for realizing the corresponding function has at least:

a needle thread steering mechanism 51 for driving the needle thread sewing mechanism 2 to rotate; and a bobbin thread turning mechanism 52 for driving the bobbin thread sewing mechanism 3 to rotate.

As shown in fig. 1, 2 and 3, the upper thread steering mechanism 51 is a steering mechanism of the upper thread sewing mechanism 2, which is realized under the combined action of a reversing motor 53, a reversing synchronous belt 54, a speed reducer 55 and the like.

As can be further seen from fig. 1 and 2, the housing 23 is further provided with an upper thread sewing mechanism 2 having at least an upper thread reciprocating puncture assembly 21 having a needle bar 211 and a multi-port needle holder 212; a multi-port needle holder 212 is connected to the needle bar 211 and moves synchronously, and the multi-port needle holder 212 is a double-port needle holder in which two needles 213 are fixed.

It should be noted that in this embodiment, the upper thread steering mechanism 51 also operates synchronously with the change of the moving direction of the template or the trend of the stitch, and the result of the operation is to make the machine head sewing device operate perpendicular to the advancing direction of the cloth. That is, during the sewing operation, the two needles 213 need to face the direction of travel of the cloth at all times, or to be parallel or even coincident with the direction of travel of the cloth. Thus in this embodiment the stitch that is sewn out, if there is no solid medium 8, is a pattern of two parallel tracks. When the stereo sewing is needed, the stereo medium 8 is allocated again, thereby forming the technical effect of the stereo sewing.

The thread hooking corresponding to the rotating shuttle at the moment is required to be perpendicular to the travelling direction of the cloth, so that the thread loops of the two upper threads can be hooked by one rotating shuttle at any time. To further illustrate the technology of this embodiment, as shown in fig. 9, fig. 9 is a schematic diagram of the hook direction of the rotating shuttle and the needle 213 direction; as seen from fig. 9, there are two line segments, namely, line segment C1 and line segment C2, and the upper and lower ends of line segment C1 and line segment C2 are respectively provided with an arrow. This pattern represents the process of the two needles 213 driving the facelines to pierce the facestock up and down and the direction of piercing. In addition, there is a circle D indicated by a dotted line, and an arrow is also formed on the circle D, which indicates the direction of the hook line of the rotating shuttle. On the upper side of circle D there is also a hatched part, which is a solid medium 8. The cross hatching means that it is the direction of extension perpendicular to the paper surface. Thus, the puncture direction of the needle and the thread hooking direction of the rotating shuttle are perpendicular.

It can thus be seen from fig. 9 that the direction of the hook line of the rotating shuttle, i.e. the arrow direction in circle D, must also be perpendicular to the direction of the solid medium 8. Therefore, in the stitch after actual sewing, the three-dimensional medium 8 is wound by the upper thread and the lower thread in a reciprocating manner from the left side to the right side in the radial direction, and when the upper thread and the lower thread are wound in a reciprocating manner, the upper thread and the lower thread pierce the fabric in a reciprocating manner, so that the tight combination of the three-dimensional medium 8 and the fabric can be finally realized.

It can also be seen from fig. 1 and 2 that a bobbin thread mounting member 6 is mounted outside the housing 23 for mounting a bobbin thread. As can be seen from fig. 2, the spool mounting member 6 has at least a wire spool 61 and a spool rod 62.

The wire coil 61 has one end fixedly connected to the casing 23, and in this embodiment, is fastened by threads; a wire coil body 611 is disposed at the other end of the wire coil 61, and the wire coil body 611 is a flat plate-mounted part; and the wire tube rod 62 is arranged on the wire coil main body 611 in a penetrating way, and the wire tube is sleeved outside the wire tube rod 62 in actual use.

As shown in fig. 2, a wire cylinder seat 63 is further arranged outside the wire cylinder rod 62, the wire cylinder rod 62 passes through the wire cylinder seat 63, and the lower ends of the wire cylinder seats 63 are separated for increasing stability. Therefore, the spool seat 63 has a function of making the spool more stable, even fixing the spool, and preventing the spool from shaking.

Referring again to fig. 3, fig. 3 is a perspective view of the hidden form driving apparatus 1 of fig. 1. As can be seen from fig. 3, the template machine according to the present embodiment further includes a bottom thread sewing mechanism 3 having at least:

a rotating shuttle member 31 for storing a base thread and hooking the upper thread to form a stitch in cooperation with the upper thread sewing mechanism 2; the rotating shuttle member 31 at least comprises a rotating shuttle seat 311, the rotating shuttle seat 311 is formed with a containing cavity 312, a shuttle shell is arranged in the containing cavity 312, and a shuttle core is arranged in the shuttle shell.

At the same time, the hook is formed on the bobbin case, and the rotating direction of the hook is to be capable of hooking the loop of the upper thread drawn by the two needles 213 at the same time. Accordingly, in the present embodiment, as shown in fig. 9, the center of the rotation axis of the bobbin case or the bobbin core is also aligned with or parallel to the direction in which the cloth is moved.

Therefore, in this embodiment, the rotating shuttle member 31 also needs to adjust the angle according to the running direction of the cloth or the trend of the stitch, and in order to achieve the above function, the bottom thread sewing mechanism 3 further includes a bottom thread steering mechanism 52 for driving the rotating shuttle member 31 to rotate; the rotation principle of the bottom thread steering mechanism 52 is similar to that of the upper thread steering mechanism 51, and the rotation principle of the bottom thread steering mechanism is that the rotation of the rotating shuttle is driven by the rotation of the rotating shuttle seat 311 after the synchronous belt is driven by a motor to rotate and then the speed is reduced by a speed reducer and the torque is increased.

In this embodiment, the rotation between the upper thread steering mechanism 51 and the lower thread steering mechanism 52 must be synchronous and conform to a certain relationship, so in practical use, an electric control system is often required to coordinate and control parameters so as to achieve synchronization.

Referring again to fig. 3, it can be seen from fig. 3 that the sewing machine further comprises a medium drawing device 4 for conveying a stereoscopic medium 8 and cooperating with the upper thread sewing mechanism 2 to form stereoscopic sewing. It should be noted that in the present embodiment, the stereoscopic medium 8 means a sewing thread other than the upper thread and the lower thread, and in the present embodiment, a cotton thread which is considerably thicker than the conventional sewing thread. In practical use, as shown in fig. 8, the stereoscopic medium 8 is located between two needles 213, and the needles 213 will press down the cloth in the process of piercing the cloth, so that the situation that two sides of the middle bulge are relatively concave can be formed. In this embodiment, the three-dimensional sewing means that the pattern with three-dimensional and aesthetic feeling can be finally formed by means of the above-mentioned concave-convex condition and the self-provided self-defined sewing path navigation function of the template machine. Is especially suitable for sewing cloth such as quilt, curtain, decorative fabric, etc.

As shown in fig. 4, fig. 4 is an assembly schematic diagram of the medium drawing device 4 in the present embodiment. As can be seen from fig. 3 and 4, the template machine shown also has a medium extraction device 4, which serves to convey a solid medium 8 and cooperates with the needle thread sewing mechanism 2 to form a solid sewing. As can also be seen from fig. 3 and 4, the medium outlet device 4 is fixedly connected to the bottom wire steering mechanism 52 and rotates synchronously with the bottom wire steering mechanism 52. So that it does not occur that the lower thread turning mechanism 52 turns by driving the lower thread sewing mechanism 3, the stereoscopic medium 8 may affect the operation of the apparatus because it is wound around the lower thread sewing mechanism 3.

In terms of the structure of the components, the medium drawing device 4 includes at least:

a medium storage mechanism for storing a stereoscopic medium 8; and

a medium thread passing mechanism for guiding the stereoscopic medium 8 into the upper thread sewing mechanism 2.

As shown in fig. 4 and 5, wherein fig. 5 is a partially enlarged view at B in fig. 4. As shown in fig. 4 and 5, the medium threading mechanism specifically further includes:

a wire holder 41 connected to the bottom wire steering mechanism 52 to achieve synchronous rotation;

a wire passing frame 42 having one end mounted on the wire clamping bracket 41; the other end of the first wire passing ring is formed with a second wire passing ring 421; and

and a wire clamping device 43 mounted on the wire clamping bracket 41.

As can also be seen from fig. 4, the medium storage means has at least:

a wire storage drum 45 having a monitoring port 451 at the bottom;

and an inductor 46 for detecting the remaining amount of the stereoscopic medium 8 in the wire storage tube 45 through the monitoring port 451. The current storage condition of the stereoscopic medium 8 can be more intuitively obtained by aligning the sensor 46 with the monitoring port 451 at the bottom of the wire storage barrel 45. As can be seen in fig. 4, there are two monitoring ports 451 respectively located at the bottom of the wire storage tube 45 and at the bottom of the side of the wire storage tube 45. In practical use, the combination of the two can enable the monitoring result to be more accurate. And the sensor 46 is linked with the electric control system, and the defect can be reported on the display screen once the stereoscopic medium 8 is detected to be less than the set value, so that workers are reminded of adding the stereoscopic medium 8.

As shown in fig. 4, the sensor 46 includes at least:

a sensor bracket 461 which rotates in synchronization with the wire storage drum 45; and

a sensor body 462 provided on the sensor holder 461, the sensor body 462 being disposed toward the monitoring port 451.

As shown in fig. 5, the wire threading device 43 includes at least:

two clips 431, between which the stereoscopic medium 8 passes;

a guide bar 432 passing through both the jaws 431 and having external threads formed at the ends thereof; a spring 433 having one end abutted against one of the clips 431; and

the other end of the spring 433 abuts against the adjusting member 434, and the adjusting member 434 is sleeved outside the external thread and is in threaded connection with the guide rod 432.

By adjusting the clamping force between the two clamping pieces 431, the degree of tightness of the fit between the stereoscopic medium 8 and the upper thread and the lower thread is adjusted, so that a more perfect stitch can be obtained.

Referring again to fig. 6, fig. 6 is a schematic structural view of the needle-thread sewing mechanism 2. As can be seen from fig. 6, a multi-port needle holder 212 is sleeved below the needle bar 211, and two needles 213 are fixedly connected to the multi-port needle holder 212. Also on one side of the needle 213 is a ball presser foot 25 which is a conventional presser foot of a stencil machine, but in this embodiment, the ball presser foot 25 is reciprocated by the needle 213, so that the hole on the ball presser foot 25 can be larger than that of the conventional needle 213, so that two needles 213 pass through at the same time.

As can also be seen from fig. 1, 2, 3 and 6, the needle thread sewing mechanism 2 also has a needle plate 22 having a needle hole 221 adapted to be pierced by the needle 213 and a medium penetration hole 222 adapted to allow the stereoscopic medium 8 to extend out of the needle plate 22. Meanwhile, the upper end surface of the needle plate 22 is further formed with a guide groove 223, and the medium perforation 222 and the needle hole 221 are respectively positioned at two ends of the guide groove 223, so that the stereoscopic medium 8 can pass through the needle hole 221 through the guide groove 223 after extending out of the medium perforation 222. Accordingly, in the present embodiment, the guide groove 223 is oriented to be located at a position intermediate the two needles 213, so that the two needles 213 can clamp the upper thread. So that the three-dimensional medium 8 can be positioned between the two needles 213 when the two needles 213 pierce the fabric up and down.

As can be seen from fig. 6, the upper end surface of the needle plate 22 further has a turning limit groove 225, and the turning limit groove 225 and the guide groove 223 are respectively located at two sides of the needle hole 221;

wherein, the steering limit groove 225 at least comprises:

an entry slot 226 that at least partially breaks open the pinhole 221 end face; and

two limiting edges 227, wherein the limiting edges 227 are positioned at two sides of the steering limiting groove 225, and the head of the limiting edge 227 extends to the notch 226;

the steering limit groove 225 is a fan-shaped groove, and two limit edges 227 are fan-shaped.

The function of the steering limit groove 225 is to limit the swing amplitude of the stereoscopic medium 8 to a certain extent, so as to reduce the situation that the stereoscopic medium 8 runs out of the penetration range of the two needles 213.

As shown in fig. 7, fig. 7 is a perspective view of the needle plate 22, and as can be seen from fig. 7, a lead groove 224 is further formed on the lower end surface of the needle plate 22, one end of the lead groove 224 is communicated with the medium through hole 222, and the other end of the lead groove 224 is directed to the medium wire passing mechanism. Specifically, as can be seen in fig. 7, the lead groove 224 has a drop shape. One end of the drop-shaped tip is directed toward the media threading mechanism. The wide end of the drop-shape has a hole site that communicates with the media perforation 222 so that the stereoscopic media 8 can enter the media perforation 222 from the wide end of the drop-shape after coming from the media threading mechanism.

It can also be seen from fig. 7 that the wire slots 224 are stepped down from the pointed end to the wide end. Thus, the three-dimensional medium 8 can be more smoothly routed, and the routing resistance is reduced.

It can also be seen from fig. 7 that the medium thread guide has at least a thread guide plate 44;

one end of the wire guide plate 44 is installed below the needle plate 22, and the other end thereof is formed with a first wire ring 441, where the first wire ring 441 is used for passing through the stereoscopic medium 8. The first wire loop 441 is used for stabilizing the routing path of the stereoscopic medium 8 and ensuring the routing stability.

[ example two ]

This embodiment has the following differences from the first embodiment: in the first embodiment, the number of the needles 213 is two, but in the actual use, by adjusting the distance between the needles 213 and reducing the diameter size of the stereoscopic medium 8, a scene in which three needles 213 work simultaneously can be realized.

The principle of the invention is as follows:

the invention requires pre-installation of multi-port needle holder 212 and corresponding placement of needle 213 prior to use. Meanwhile, the stereoscopic medium 8 is placed in the wire storage cylinder 45 in advance, and the stereoscopic medium 8 sequentially passes through the wire clamping device 43, the second wire passing ring 421 and the first wire passing ring 441, enters from the wire guiding groove 224, passes out from the medium perforation 222 and is arranged in the guide groove 223 in advance.

Correspondingly, the thread hooking direction of the rotating shuttle is consistent with the arrangement direction of the needle; the guide groove 223 should pass through the middle of the two needles 213, and the direction of the guide groove 223 (i.e. the direction of the stereoscopic medium) is perpendicular to the hook direction of the rotating shuttle.

With the assurance that the stereoscopic medium is already present in the guide groove 223, the template is placed and fixed, and then sewn according to a normal template machine.
