Description

Technical Field

[0001] The present application relates to the technical field of embroidery machines, and in particular to a dual-motor multi-sequin embroidery device. Background Art

[0002] With the improvement of the quality of life, people have higher and higher requirements for the quality and beauty of gold leaf embroidery, so the multi-gold leaf device has become the main trend. For the gold leaf embroidery device that uses the reciprocating movement of the shift fork to send the film, the number of motors used in the gold leaf embroidery device and the accuracy of the transmission mechanism have a great influence on the running stability of the device. The large number of motors and the large weight are prone to unstable center of gravity, which will affect the stability of the device operation. In order to solve the technical defects of heavy weight, a single-motor double-gold leaf device and a multi-gold leaf embroidery machine head that uses a single motor to complete the cutting and feeding actions are designed, such as CN202519464U and CN106283440B. In view of the poor accuracy of the transmission structure, it will also affect the shift fork. The accuracy of the fork feeding affects the feeding accuracy of the sequins. Therefore, the existing sequin feeding structure preferably adopts a swing arm and a fork connecting rod to cooperate and drive the sequins. In order to make the sequin embroidery device meet the characteristics of compact structure, small size, light weight, stable operation and high accuracy, due to structural limitations, the multi-sequin embroidery device with a motor-driven cutter assembly in the prior art is usually a dual-motor dual-sequin embroidery device. The multi-sequin embroidery device can be formed by combining two or more dual-sequin embroidery devices. The more dual-sequin embroidery devices are used, the heavier they are, the more space they occupy and the higher the cost. It can be seen that the existing multi-sequin embroidery device with an independent head still cannot better meet the use of multi-sequin embroidery. Utility Model Content

For the multi-sequin embroidery machine formed by the combination of the multi-sequin embroidery machine heads 1, the number of the multi-sequin embroidery machine heads 1 used is small, the weight is light, the space occupied is small, and it is more convenient to install and use.

[0025] In the present application, the specific structure of a pair of first paddle assemblies that share the second motor 114 to drive the sheet feeding is as follows: the first paddle assembly includes a linked second fork link 13 and a link driving rocker rod 111, the second fork link 13 is hinged on the side plate of the base 11, a reset torsion spring 16 is provided between the second fork link 13 and the base 11, and the reset torsion spring 16 can drive the second fork link 13 to automatically reset. When the second motor 114 is used to drive the fork to move forward in the sheet feeding channel to feed the sheet, a limit block is provided on the base 11 to limit the automatic reset limit position of the second fork link 13 to ensure that the fork can reliably act on the perforation of the corresponding gold sheet. When the second motor 114 is used to drive the fork to move backward in the sheet feeding channel, a limit block is provided on the base 11 to limit the automatic reset limit position of the second fork link 13 to control the accuracy of sheet feeding. The first motor 110 is used to drive The specific structure of the second paddle assembly and the cutter assembly 19 is as follows: the second paddle assembly includes a first fork link 12 with a driving swing arm, the first fork link 12 is hinged on the side plate of the base 11, a reset torsion spring 16 is provided between the first fork link 12 and the base 11, a cutter driving swing frame 191 is hinged on the side plate of the base 11, the cutter driving swing frame 191 has a cutter driving arm, and the first swing arm 17 can drive the first fork link 12 to swing against the driving swing arm of the first fork link 12. The shift fork connected to the shift fork connecting rod 12 moves in the corresponding sheet feeding channel. When the second swing arm 18 is pressed against the cutter driving arm of the cutter driving swing frame 191, it can drive the cutter pressure rod 192 connected to the cutter driving swing frame 191 to be pressed down. The lower end of the cutter pressure rod 192 is connected to the cutter shaft 193 installed on the base 11 through a rotating arm. The cutter pressure rod 192 is pressed down to drive the cutter shaft 193 to rotate, thereby driving the gold sheet cutter 194 installed on the cutter shaft 193 to be pressed down to cut the gold sheet.

[0026] The connecting rod driving the rocker arm 111 in the present application that acts on the shift shaft can extend in any direction. The direction of the rocker arm part is designed according to the use requirements, and a pair of connecting rod driving the rocker arm 111 are arranged opposite to each other. When the second motor 114 is forward and reversed, it drives a pair of shift forks of the first shift piece assembly to move in the same direction in the film feeding channel. A pair of connecting rod driving the rocker arm 111 arranged opposite to each other is used to cooperate with the third swing arm 112, so that the structure is more compact and suitable for use in small space structures.

[0027] Preferably in the present application, the rocker portion of the connecting rod driving the rocker arm 111 that acts on the shift shaft extends in the lateral direction, and the connecting rod driving the rocker arm 111 of the first shifter assembly close to the gold sheet outlet is located above the connecting rod driving the rocker arm 111 of the other first shifter assembly, and the second motor 114 is used to drive the shift fork to move backward in the sheet feeding channel. This structure can make the second motor 114 and the first motor 110 stacked from bottom to top, and the structure is more compact.

[0028] When the connecting rod driving rocker arm 111 of the first paddle assembly near the gold sheet outlet is located below the connecting rod driving rocker arm 111 of the other first paddle assembly, the second motor 114 is used to drive the shift fork to move forward in the sheet feeding channel; when the connecting rod driving rocker arm 111 of a pair of first paddle assemblies extends in the vertical direction, when the connecting rod driving rocker arm 111 of the first paddle assembly near the gold sheet outlet extends upward and the connecting rod driving rocker arm 111 of the other first paddle assembly extends downward, the second motor 114 is used to drive the shift fork to move backward in the sheet feeding channel.

[0029] In order to make the structure of the present application more compact and less prone to interference, the second fork link 13 of the first paddle assembly and the link driving rocker 111 are installed on the side panel of the base 11 through the corresponding connecting shaft 15, and the fork link and the link driving rocker 111 are respectively located on both sides of the side panel to avoid the link driving rocker 111 occupying the space above the film feeding channel, thereby avoiding interference between the link driving rocker 111 and the first fork link 12 and the connecting shaft 15 connected to the first fork link 12.

[0030] The connecting rod driving rocker arm 111 in the present application can also be integrally formed or coaxially connected with the corresponding second fork connecting rod 13 so that the connecting rod driving rocker arm 111 and the second fork connecting rod 13 are located on the same side of the side plate of the base 11, a pair of first paddle assemblies are arranged adjacent to each other, and the second paddle assembly and the cutter pressure rod 192 of the cutter assembly 19 are arranged adjacent to each other.

[0031] When the installation space is large, a metal piece structure can also be formed by adding a motor and a pair of first paddle components to the multi-metal piece embroidery machine head 1 of the present application.

[0032] In the present application, the shift shaft connected to the third swing arm 112 is a cylindrical pin or a roller 113, the first swing arm 17 is connected to a shift shaft that can be pressed against the driving swing arm of the first fork link 12, and the second swing arm 18 is connected to a shift shaft that can be pressed against the cutter driving arm of the driving swing frame 191. The setting of the shift shaft can reduce the contact friction and make the movement process smoother.

[0033] In the present application, a distribution method of multiple feeding channels is: they are arranged in a flat shape, and multiple forks corresponding to the feeding channels are installed in a staggered manner along the distribution direction of the feeding channels. When the same gold foil cutter 194 is used to cut the gold foil, all the feeding channels use the same or different colors of gold foil of the same size and specifications for embroidery.

[0034] In the present application, another distribution method of multiple feeding channels is: multiple feeding channels are distributed in layers from bottom to top, and when all gold leaf chains are cut using the same gold leaf cutter 194 or multiple gold leaf cutters 194 with cutting edges located on the same vertical plane, all feeding channels use gold leaves of the same size and specifications of the same color or different colors for embroidery.

[0035] In an embodiment of the present application, the distribution method of multiple film feeding channels is as follows: the multiple film feeding channels are distributed in a stacked manner from bottom to top, the size of the gold flakes transported by the film feeding channels decreases from bottom to top, and all the gold flakes delivered use the same embroidery needle to complete the embroidery work, which is the same as the distribution method of the film feeding channels in CN202116836U.

[0036] In the present application, another distribution method of multiple film feeding channels is: multiple film feeding channels are distributed in layers from bottom to top, and the overall size of the gold films transported by the film feeding channels gradually decreases from bottom to top. Gold films of the same specifications are arranged adjacent to each other and can be cut using the same gold film cutter 194, such as four layers of three specifications or five layers of three specifications. Four layers of three specifications means that there are two layers of gold films with the same specifications, and five layers of three specifications means that there are two specifications of gold films with double layers. All the gold films sent out are embroidered using the same embroidery needle.

[0037] In the embodiment of the present application, in order to make the structure of the present application more compact, the second paddle assembly is located between a pair of first paddle assemblies, and the setting of a pair of connecting rod driving rocker 111 is facilitated by increasing the gap between a pair of second fork connecting rods 13, and the installation of the first swing arm 17 and the second swing arm 18 is facilitated by increasing the gap between the first fork connecting rod 12 and the cutter driving swing frame 191. The pair of first paddle assemblies are respectively used to deliver the gold sheets on the top layer and the bottom layer, and the second paddle assembly is used to deliver the gold sheets on the middle layer.

[0038] like Figure 3 and Figure 5 As shown, in the embodiment of the present application, the cutter assembly 19 also includes a cutter shaft 193 and a plurality of gold sheet cutters 194 coaxially mounted on the cutter shaft 193. The gold sheet cutter 194 for cutting off the top layer of gold sheets has a convex strip 1941 extending along the length direction of the gold sheet cutter (194). Since the size of the gold sheet on the top layer is the smallest, the thickness of the gold sheet cutter 194 used will be the smallest, thereby reducing the strength of the gold sheet cutter 194. The strength of the gold sheet cutter 194 is increased by providing the convex strip 1941. The convex strip 1941 can also abut against the base 11 during the downward pressing process of the gold sheet cutter 194 to prevent the gold sheet cutter 194 from continuing to be pressed downward, thereby preventing the gold sheet cutter 194 from being excessively pressed downward and causing damage to the gold sheet on the lower layer.

[0039] In the embodiment of the present application, the gold sheet cutter 194 for cutting off the top layer of gold sheet is also provided with an avoidance groove 1942 for avoiding the embroidery needle, which can maintain the strength of the gold sheet cutter 194 while avoiding the collision between the embroidery needle and the gold sheet cutter 194 to cause needles.

[0040] When the present application is used, the controller is used to control the first motor 110 and the second motor 114 to work in sequence or simultaneously: when a single gold sheet is needed for embroidery, the first motor 110 or the second motor 114 is actuated to realize the corresponding gold sheet feeding, and after the feeding is completed, the first motor 110 is used to control the cutter assembly 19 to complete the cutting of the gold sheet; when double gold sheets are needed for superimposed embroidery, the first motor 110 and the second motor 114 are controlled to rotate forward and reversely to complete the feeding of the upper and middle layers of gold sheets or the feeding of the upper and lower layers of gold sheets or the feeding of the middle and lower layers of gold sheets, and after the feeding is completed, the first motor 110 is used to control the cutter assembly 19 to complete the cutting of the two layers of gold sheets, and then the embroidery needle is used to embroider at one time. When three gold sheets are needed for superimposed embroidery, the first motor 110 and the second motor 114 are controlled to rotate forward and reversely to complete the feeding of the upper, middle and lower layers of gold sheets. After the feeding is completed, the first motor 110 is used to control the cutter assembly 19 to cut the gold sheets. When double / triple gold sheets are needed for superimposed embroidery, the embroidery needle can also be used to perform single-piece layer-by-layer superimposed embroidery at the same position, that is, the gold sheets are dropped one by one, and embroidery is performed after the single sheet is dropped. When the specifications of the gold sheets sent in this application are different, it can meet the use of stacked gold sheet embroidery with a small bottom and a large top or large at both ends and a small middle. The superimposed embroidery of gold sheets of different colors set by stacking will produce different effects outdoors or at different angles.

[0041] 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.
