Description

[Technical field]

[0001] The utility model belongs to the technical field of embroidery equipment, in particular to an embroidery machine. [Background technology]

[0002] In the embroidery machine industry, there are single-frame machines and half-frame machines. The difference between single-frame machines and half-frame machines is the machine format. A single-frame machine has a larger format, so the machine is deeper from front to back and occupies more space, but the cost of holding is high. A half-frame machine can embroider the same grey fabric, and the same size of fabric, and the number of cloth clamping times is twice that of a single-frame machine. However, after the cloth clamping, the fabric that is not embroidered on the embroidery frame cannot be placed, so currently only relatively small fabrics can be embroidered. [Contents of the utility model]

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide an embroidery machine and a cloth supporting device thereof, so as to solve the problem that the cloth not embroidered on the embroidery frame cannot be placed when the half-frame machine is embroidering large-format cloth.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] First, an embroidery machine cloth supporting device is provided, comprising an embroidery frame assembly, wherein the embroidery frame assembly comprises an embroidery frame and an X-driven movable plate for driving the embroidery frame to move along an X direction, and the embroidery machine cloth supporting device further comprises a cloth supporting member arranged at the rear side of the embroidery frame, wherein the cloth supporting member is connected to the X-driven movable plate so that the X-driven movable plate drives the embroidery frame and the cloth supporting member to move synchronously.

[0006] Preferably, the cloth support member includes an upper support plane, the rear side of the upper support plane is connected to a rear support edge supported on the X-driven moving plate, and the front side of the upper support plane is connected to a front support edge supported on the front side of the X-driven moving plate.

[0007] Preferably, the rear support edge is connected to a guide wheel supported on the X-driven movable plate.

[0008] Preferably, the front supporting edge is connected with a front flange.

[0012] On the other hand, the utility model also provides an embroidery machine, and the embroidery machine is provided with the cloth supporting device.

[0013] The technical solution adopted by the utility model has the following beneficial effects:

[0014] A cloth-supporting member is arranged at the rear side of the embroidery frame, and the cloth-supporting member is connected to the X-driven movable plate. In this way, after the cloth clamping is completed, the grey cloth on the half-frame machine that is not unfolded on the embroidery frame for embroidery can be stacked and placed on the cloth-supporting member; and because the cloth-supporting member is connected to the X-driven movable plate, the embroidery frame is also connected to the X-driven movable plate, and the X-driven movable plate drives the embroidery frame and the cloth-supporting member to move synchronously, and the relative position of the cloth-supporting member and the embroidery frame is constant, so that the cloth placed on the cloth-supporting member moves together with the cloth unfolded on the embroidery frame for embroidery, without affecting the normal embroidery.

[0015] When the cloth needs to be clamped for the second time, the machine head stops working, the cloth clamp is loosened, the unembroidered cloth is unfolded and placed on the embroidery frame, the embroidered cloth is stacked and placed on the cloth support, the cloth clamp is clamped again, and then the embroidery is continued.

[0016] In addition, the rigidity of the cloth support can reinforce the X-driven moving plate, making the embroidery frame more stable.

[0034] Reference Figures 1 to 9 As shown, the utility model provides a multifunctional embroidery machine, comprising a frame 2, a modular combined head assembly 1 installed on the frame 2, and an embroidery frame assembly 3.

[0035] Among them, the modular combined head assembly 1 includes a head bracket, which includes a base 11, a support beam 12, a suspension beam 13 connected to the upper part of the support beam and extending forward, and a cross beam 14 connected to the front end of the suspension beam. The front side of the cross beam 14 is provided with a first mounting portion 141 and a second mounting portion 142 side by side on the left and right. The first mounting portion 141 is mounted with a first functional head, and the second mounting portion 142 is mounted with a second functional head.

[0036] like Figure 1 As shown, in one embodiment, the first functional machine head is a flat embroidery machine head 15, and the second functional machine head is a tape embroidery machine head 16.

[0037] like Fig. 9 As shown, in another embodiment, the first functional machine head is a flat embroidery machine head 15, and the second functional machine head is a towel machine head 17.

[0038] Of course, it is understandable that both the first functional head and the second functional head can be replaced by other functional heads, such as a cap embroidery head.

[0039] In order to install the shuttle bed, a shuttle bed installation platform 111 for installing the shuttle bed is provided in the middle area of ​​the upper surface of the base 11. The shuttle bed installation platform 111 is provided with a shuttle bed installation hole. The shuttle bed is installed through the shuttle bed installation hole and the installation bolts to facilitate the installation and replacement of the shuttle bed. Referring to the prior art, a conventional shuttle bed can be used in conjunction with a flat embroidery machine head 15, a tape machine head 16, etc. for embroidery, but a towel shuttle bed must be provided in conjunction with a towel machine head. Both a conventional shuttle bed and a towel shuttle bed can be installed on the shuttle bed installation platform 111.

[0040] Specifically, the first mounting portion 141 and the second mounting portion 142 include a mounting boss and a head mounting hole provided on the mounting boss. The first functional head and the second functional head are mounted through the head mounting hole and mounting bolts to facilitate the installation and replacement of the heads.

[0041] The first function machine head and the second function machine head can be selected to make a variety of combinations, and the corresponding machine heads and shuttle beds can be matched. In this way, different combinations can quickly build multiple machine models, such as pure flat embroidery, pure tape, pure towel, mixed tape, mixed towel, etc.

[0042] In addition, referring to the prior art, the embroidery frame assembly 3 includes an embroidery frame 31 and an X-driven moving plate 33 for driving the embroidery frame to move along the X direction. The upper surface of the base 11 is provided with a drive installation platform 112 for installing the embroidery frame drive on both sides.

[0043] Furthermore, a transmission beam is provided below the suspension beam 13, and a transmission assembly is provided inside the transmission beam, and the transmission assembly is in transmission connection with the first functional head and the second functional head. A transmission shaft is provided between the first functional head and the second functional head, and the transmission shaft is connected to the head main shafts of the first functional head and the second functional head through a coupling component.

[0044] Specifically, the base 11, support beam 12, suspension beam 13 and cross beam 14 are separately processed and formed and connected as a whole through fasteners. The base, support beam, suspension beam and cross beam are processed with connecting surfaces for mutual connection and positioning. In addition, the fasteners are bolts, and the support beam, suspension beam and cross beam are square steel. The base is welded into one by multiple sections of steel.

[0045] Since the head bracket is designed as a split structure, the processing of each component after splitting is simple, and the requirements for processing equipment are greatly reduced. With simple tooling and fixtures, it is suitable for mass production, and can ensure high processing accuracy. It can also be used as a universal stock and semi-finished product inventory, greatly shortening the manufacturing cycle. Moreover, it is suitable for small-batch customization and can meet the requirements of mass production. After the processing accuracy of each split component is guaranteed, it is assembled together with fasteners, and the installation is very convenient. It can avoid the restriction of the frame structure layout due to processing requirements of the one-piece structure frame. In addition, during the assembly process, the relative position of each split component can be adjusted to ensure the overall accuracy after the assembly is completed.

[0046] Haute couture embroidery has higher requirements, and timely adjustment and stop loss are very necessary during embroidery. However, batches of fabrics are often inspected after forming and then graded. Once the embroidery is found to be unqualified, the cost is high. To address this problem, a flower inspection device 32 can be provided on the embroidery frame. The flower inspection device 32 includes a flower inspection window 321 provided on the embroidery frame, a transparent support plate 322 installed on the flower inspection window, and a flower inspection lighting lamp 323 installed on the lower side of the embroidery frame. The light of the flower inspection lighting lamp 323 is irradiated toward the transparent support plate 322.

[0047] Since the embroidery frame is provided with a flower inspection device, during the embroidery process, after the embroidery of the local area pattern is completed, the flower inspection can be carried out at the flower inspection window 321. Once the embroidery is found to be unqualified, it can be adjusted in time to avoid losses caused by unqualified products after they are finished.

[0048] Since a transparent support plate is installed at the flower inspection window, the light of the flower inspection lighting lamp shines on the transparent support plate and is projected onto the embroidery, making it easy to observe whether the pattern on the embroidery is qualified.

[0049] Preferably, the flower inspection window 321 is arranged in the central area of ​​the embroidery frame, because this is also the usual setting area of ​​the pattern on the fabric. The periphery of the flower inspection window 321 is provided with a limiting frame, and the transparent support plate 322 is supported on the limiting frame and the upper surface is flush with the upper surface of the embroidery frame. Since the transparent support plate is supported on the limiting frame and the upper surface is flush with the upper surface of the embroidery frame, it is equivalent to being integrated with the embroidery frame, and does not affect the integrity of the embroidery frame, and thus does not affect the flatness of the fabric, and it is also convenient to move the pattern to the flower inspection window position for fabric inspection.

[0050] Specifically, the limiting frame and the transparent support plate are connected by fixing screws. The fixing screws are hexagon socket screws, the limiting frame is provided with a threaded hole, and the transparent support plate is provided with a countersunk hole connected to the screw head of the fixing screw. In this way, the transparent support plate is placed from above, and then the fixing screws are tightened from above, and after the screws are tightened, the screw heads are immersed in the countersunk holes, which will not affect the flatness of the fabric.

[0051] In this embodiment, the transparent support plate 322 is made of transparent plastic. It looks similar to organic glass, has a certain hardness and good light transmittance, but is not easy to break and has good wear resistance, so it has a long service life. It is understandable that it can also be replaced by transparent glass.

[0052] Furthermore, the flower inspection window 321 and the transparent support plate 322 are both rectangular structures with chamfers at the four corners. The flower inspection lighting lamp 323 is a long strip light and is arranged at the front side of the flower inspection window. The flower inspection lighting lamp is provided with a lampshade for guiding the light to irradiate the transparent support plate.

[0053] It is understandable that, for different fabrics, the flower inspection lighting can be selected to facilitate the inspection of the fabric in the subsequent embroidery process.

[0054] Referring to the embroidery machines in the prior art, there are two types of embroidery machines in the industry: one-frame machines and half-frame machines. The difference between a one-frame machine and a half-frame machine is the size of the machine. A one-frame machine has a larger size, so the machine is deeper from front to back, and occupies a larger space, but the cost of holding is high. A half-frame machine can embroider the same grey cloth, and the same size of cloth, and the number of cloth clamping times is twice that of a one-frame machine. However, after the cloth is clamped, the cloth that is not embroidered on the embroidery frame needs to be stored, so a cloth support device is designed.

[0055] The cloth-supporting device includes a cloth-supporting support 34 disposed at the rear side of the embroidery frame, and the cloth-supporting support 34 is connected to the X-driven movable plate 33. In this way, after the cloth clamping is completed, the grey cloth on the half-frame machine that is not unfolded on the embroidery frame for embroidery can be stacked and placed on the cloth-supporting support 34; and because the cloth-supporting support is connected to the X-driven movable plate, the embroidery frame is also connected to the X-driven movable plate, the X-driven movable plate drives the embroidery frame and the cloth-supporting support to move synchronously, and the relative position of the cloth-supporting support and the embroidery frame is constant, so that the cloth placed on the cloth-supporting support moves together with the cloth unfolded on the embroidery frame for embroidery, and does not affect the normal embroidery.

[0056] When the cloth needs to be clamped for the second time, the machine head stops working, the cloth clamp is loosened, the unembroidered cloth is unfolded and placed on the embroidery frame, the embroidered cloth is stacked and placed on the cloth support, the cloth clamp is clamped again, and then the embroidery is continued.

[0057] In addition, the rigidity of the cloth support can reinforce the X-driven moving plate, making the embroidery frame more stable.

[0058] Specifically, the cloth-supporting member 34 includes an upper supporting plane 341, the rear side of which is connected to a rear supporting edge 342 supported on the upper surface of the X-driven moving plate, and the front side of which is connected to a front supporting edge 343 supported on the front side of the X-driven moving plate. The front and rear width of the upper supporting plane 341 basically covers the entire width of the X-driven moving plate, so that the supported cloth is not easy to fall off or hook during embroidery.

[0059] Furthermore, the rear support edge 342 is connected to a guide wheel 345 supported on the X-driven movable plate, so as to facilitate relative adjustment of the position of the cloth support member 34 .

[0060] Further, the front support edge 343 is connected with a front flange 344. By arranging the front flange, the structural strength of the cloth support can be enhanced. In addition, the front flange is provided with an avoidance hole 346 for avoiding screws.

[0061] Preferably, the cloth support member 34 is a sheet metal member, which has the advantages of light weight, high strength, low cost, and good mass production performance.

[0062] Furthermore, rounded corners are provided between the upper support plane and the rear support edge and the front support edge, so as to facilitate forming by sheet metal processing and avoid damage to the fabric.

[0063] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
