Description

Technical Field

[0001] The present application relates to the technical field of embroidery machines, and in particular to a multifunctional embroidery machine. Background Art

[0002] As people have higher and higher requirements for patterns on clothing, household items and other items, they not only hope that the patterns will be more three-dimensional, but also hope that the patterns will be more colorful. Usually, it is necessary to use an embroidery machine to sew beads or gold flakes on the above items. In order to make the pattern more beautiful, sometimes it is necessary to mix several different beads and gold flakes together. Due to the limited installation space at the head of the machine, using multiple independent pure bead embroidery devices and pure gold flake embroidery devices at the same time will make the head of the machine crowded and affect the working line of sight, and it is not suitable for installation in a small space. Therefore, a multifunctional embroidery device that integrates the bead embroidery device and the gold flake device has appeared, but The existing multifunctional embroidery devices are all designed to transport gold sheets and embroidery beads to the same embroidery needle. When the gold sheets and beads need to be embroidered using multiple embroidery needles with fixed positions, the gold sheets and beads need to be transported under different embroidery needles, and a corresponding mechanism will be used to move the multifunctional embroidery machine head that combines the gold sheets and beads as a whole as a whole. During the movement, not only is it easy to have unsmooth movement due to the overall weight of the multifunctional embroidery machine head, but it will also cause other embroidery needles to be unable to embroider due to interrupted feeding. It can be seen that the existing multifunctional embroidery device method meets the situation that the gold sheets and embroidery beads are transported to the bottom of different embroidery needles so that multiple embroidery needles work at the same time, and the work efficiency is low.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the implementation modes and the accompanying drawings. Here, the illustrative implementation modes and descriptions of the present application are used to explain the present application, but are not intended to limit the present application.

[0029] refer to Figures 1 to 7 ,like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the present embodiment provides a multifunctional embroidery machine, including a multi-specification bead embroidery device 1 and a multi-sequin embroidery device 2. The multi-specification bead embroidery device 1 includes a plurality of bead dropping and feeding units 12, and the plurality of bead dropping and feeding units 12 are distributed along the same arc at an angle. The specific structure of the multi-specification bead embroidery device 1 can refer to the applied patent documents CN109706654A or / and CN218263070U. The bead feeding mechanism is a single-specification bead feeding mechanism or a multi-color color-changing bead feeding mechanism. The multi-sequin embroidery device 2 is connected to the multi-specification bead embroidery device 1 through a position adjustment mechanism 3. The position adjustment mechanism 3 is used to drive the multi-sequin embroidery device 2 to move along the needle bar distribution direction set on the machine head so that the sequins can be transported to the bottom of different needle bars.

[0030] Specifically, when the same embroidery needle is used to embroider gold sheets and beads, the gold sheets and beads can be alternately transported to the bottom of the same needle bar, or the gold sheets and beads can be staggered in the height direction by utilizing the different height positions of the output gold sheets and embroidery beads to achieve simultaneous transport of the gold sheets and beads to the bottom of the same needle bar for overlapping embroidery, that is, the gold sheets can be located above or below the beads, and the beads delivered by the multiple bead-dropping and bead-feeding units 12 can be located at the same height or at different heights to be used in conjunction with the gold sheets. When different embroidery needles are used to embroider gold sheets and beads, the position adjustment mechanism 3 is used to drive the multiple gold sheet embroidery device 2 to move along the needle bar distribution direction set on the machine head so that the gold sheets can be transported to the bottom of the corresponding needle bar, so that the corresponding embroidery needle completes the bead embroidery work, and the corresponding embroidery needle completes the gold sheet embroidery work, thereby achieving the overlapping of beads and gold sheets. The situation of using different embroidery needles to embroider at the same time improves the work efficiency; the structure of the present application can also be that the multi-specification bead embroidery device 1 is connected to the multi-sequin embroidery device 2 through the position adjustment mechanism 3. During operation, the position of the sequins remains unchanged, and the position adjustment mechanism 3 is used to drive the multi-specification bead embroidery device 1 to move along the distribution direction of the needle rod so that the beads are sent to the bottom of different needle rods; the structure of the present application can also be that another position adjustment mechanism 3 is used to connect the present application to the embroidery machine frame, and the corresponding position adjustment mechanism 3 is used to drive the overall movement of the present application, and the corresponding position adjustment mechanism 3 is used to make the multi-specification bead embroidery device 1 or the multi-sequin embroidery device 2 move separately; during operation, the position of the embroidery needle remains unchanged, and the sequins and / or embroidery beads move to cooperate with different embroidery needles, so that the pattern is richer and the work efficiency is higher.

[0031] In the embodiment of the present application, preferably, the multiple sequin outlets of the multiple sequin embroidery device 2 are stacked and distributed in the vertical direction. The specific structure of the multiple sequin embroidery device 2 can refer to CN202519464U. In actual use, the multiple sequin embroidery device 2 can also use a multiple sequin embroidery device with multiple sequin outlets laid flat along a horizontal plane, which can refer to CN102978847B.

[0032] The position adjustment mechanism 3 can be a linear drive mechanism or a curved drive mechanism. When the position adjustment mechanism 3 is a curved drive mechanism, the position adjustment mechanism 3 includes a limiting slide rail 31 with a curved groove and a driving block with a linear slide groove. The linear slide groove is perpendicular to the driving direction of the curved groove. The driving block is connected to the linear mechanism. The curved groove of the limiting slide rail 31 faces downward or upward. The slider 32 sliding along the curved groove of the limiting slide rail 31 is connected to the multi-sequin embroidery device 2, and the slider 32 is slidably matched with the linear slide groove. When the linear mechanism drives the driving block to move, it drives the slider 32 to move along the linear slide groove and the curved groove at the same time. The extension direction of the curved groove is The slider 32 is provided with a roller or a wheel that cooperates with the linear slide groove and the curved groove. The curved groove is regular or irregular, that is, when the slider 32 moves along the curved groove, it moves forward and backward at intervals according to the shape of the curved groove. When moving forward, the sequins can be delivered to the bottom of the embroidery needle, and the opposite is true when moving backward. The curved groove is composed of multiple sections of arc grooves and flat grooves. When the slider 32 moves along the arc groove, the front and rear positions of the multi-sequin embroidery device 2 will be adjusted. When the slider 32 moves along the flat groove, the multi-sequin embroidery device 2 maintains continuous forward or backward positions, so that the multi-sequin embroidery device 2 can work continuously without affecting the embroidery needle in the middle during the offside process.

[0033] When the position adjustment mechanism 3 is a linear drive mechanism, the position adjustment mechanism 3 may be a mechanism formed by a combination of an air cylinder, an oil cylinder, a linear motor, a gear rack assembly, a screw nut assembly and a sliding pair.

[0034] In the embodiments of the present application, preferably, Figure 1 , Figure 3 and Figure 4 As shown, the position adjustment mechanism 3 includes a limiting slide rail 31 and a driving motor both of which are arranged on the multi-specification bead embroidery device 1. A plurality of pins 33 are arranged on a slider 32 that slides with the limiting slide rail 31. A spiral groove is arranged on the outer peripheral surface of a color-changing cam 34 connected to the driving motor. When the color-changing cam 34 rotates, the pin 33 moves along the spiral groove. The multi-sequin embroidery device 2 is connected to the slider 32. When the color-changing cam 34 rotates, the pin 33 is driven to move, thereby driving the slider 32 to move. The movement of the slider 32 drives the multi-sequin embroidery device 2 to move as a whole, so that the sequins can be transported to different needle bars for embroidery work. By arranging a spiral groove on the color-changing cam 34, the pitch is large, thereby making the adjustment process fast, which is convenient for adapting to the use of high-speed embroidery machines.

[0035] In the embodiment of the present application, preferably, the spiral groove is composed of spiral grooves 341 with arcuate groove walls and planar grooves 342 with planar groove walls that are alternately arranged.

[0036] Specifically, the plane groove 342 is a plane that coincides with the radial surface. By setting the plane groove 342, when the pin shaft 33 is located within the range of the plane groove 342, the slider 32 does not move, and the driving motor can make the gold sheet stop stably under the corresponding needle bar for a short time without stopping the machine, thereby realizing continuous and accurate sheet feeding, and the driving motor can reduce sheet feeding errors without stopping the machine, thereby achieving high work efficiency.

[0037] In the embodiment of the present application, the center angle range between two adjacent planar grooves 342 is 90° to 360°, and the pitch between the two planar grooves 342 is the center distance between the two needle bars. By combining the pitch and the center angle between the two planar grooves 342, the gold sheet can be accurately transported to the corresponding needle bar for embroidery.

[0038] Preferably in the present application, the center angle between two adjacent planar grooves 342 is 180°, that is, after the color-changing cam 34 rotates 180°, the sequins transported by the multiple sequin embroidery device 2 will move under another adjacent needle bar.

[0039] In the present application, preferably, the pin 33 is a roller pin. The use of the roller pin can reduce the friction between the pin 33 and the spiral groove, so that the slider 32 moves more smoothly and can reduce the wear of the pin 33 and the spiral groove.

[0040] In the embodiments of the present application, Figure 6 and Figure 7 As shown, the multi-sequin embroidery device 2 includes a sequin cutter 21 capable of pitching and swinging, and the sequin cutter 21 includes a connecting portion 211 connected to a cutter driving mechanism, a blade portion 212 connected to the connecting portion 211, and a guide portion 213 arranged on one end of the blade portion 212, and the guide portion 213 is deflected by a certain angle to the side away from the needle rod.

[0041] Specifically, the guide portion 213 is located on one end of the blade portion 212 close to the multi-specification bead embroidery device 1. When the multi-sequin embroidery device 2 approaches the multi-specification bead embroidery device 1 under the action of the position adjustment mechanism 3, the guide portion 213 can be used to avoid the blade portion 212 from colliding with the embroidery needle to cause needles. The outer side surface of the connection between the blade portion 212 and the guide portion 213 is a smooth transition arc surface.

[0042] In the embodiment of the present application, preferably, the guide part 213 is close to the multi-specification bead embroidery device 1, and the guide part 213 is located above the elastic bead feeding clamp of the multi-specification bead embroidery device 1. It is avoided that the guide part 213 and the elastic bead feeding clamp of the corresponding bead feeding unit 12 interfere with each other and affect the coordination embroidery of the sequins and beads.

[0043] Specifically, the top surface of the guide portion 213 is flush with the top surface of the blade portion 212 , and the width of the guide portion 213 is smaller than the width of the blade portion 212 .

[0044] like Figure 6 As shown, in the embodiment of the present application, the aggregate end of the bead feeding base 121 of the falling bead feeding unit 12 is in the shape of a triangular tip.

[0045] Specifically, the end of the bead feeding base 121 close to the needle rod is the aggregation end, and the aggregation end of the bead feeding base 121 is in the shape of a triangular tip, so that the assembly of multiple bead feeding units 12 can be more compact, and the bead feeding pulley arranged on the bead feeding base 121 and the connected bead feeding base 121 do not interfere with each other, and the limited space can be utilized to use as many bead feeding units as possible to make the embroidery pattern richer.

[0046] In an embodiment of the present application, the bead rack 122 of the bead dropping and feeding unit 12 is V-shaped, and one connecting arm of the bead rack 122 is fixedly arranged on the side of the bead feeding base 121 and is parallel to the movement direction of the elastic bead feeding clamp, and the bead passing hole on the other connecting arm of the bead rack 122 cooperates with the corresponding bead stringing wire.

[0047] Specifically, the rear end of the bead sending base 121 away from the aggregation end is widened, and the bead passing rack 122 is fixedly installed on the top surface of the bead sending base 121, and the fixing part of the bead passing rack 122 is located at the widened part. With this structure, the size of other parts of the bead sending base 121 can be correspondingly reduced, thereby making the width of the bead sending base 121 close to the aggregation end as small as possible, making the structure more compact and small.

[0048] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the embodiments of the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
