Detailed Description

The invention will be further explained by means of specific embodiments with reference to the drawings, in which:

the existing machine embroidery frame 11 is generally made of metal section bars such as aluminum section bars, is convenient for shape design and manufacture, is a square frame as a whole and can move on a machine track; in addition, a holding crosspiece is arranged on the embroidery frame 11 body, and the traditional embroidery material clamp 5 needs to be matched to hold the edge part of the embroidery material so as to fix the embroidery material, as shown in fig. 2. Briefly, the overall shape of the embroidery clamp 5 is similar to a "U" shape or a "C" shape or a "V" shape (although the actual clamp is not limited to a completely straight or rounded "U" shape or "C" shape or "V" shape, but may have a certain curvature to obtain better toughness and clamping effect, and at the same time, needs to be matched with the embroidery frame 1 for final shaping, and belongs to the conventional technical means). This is the simplest clamping fit of the prior embroidery frame 1 and the embroidery clamp 5, and is generally only suitable for single-layer embroidery. Because the embroidery machine utilizes the elastic deformation principle and the buckle form to directly clamp, the embroidery material can change the tension in the embroidery process, and the embroidery material clamp 5 can possibly jump off, thereby influencing the quality of the embroidery and being dangerous; when the embroidery clamp 5 is snapped or pulled off by force, the embroidery clamp is easily pulled and torn, and the embroidery is torn or the position of the embroidery is deviated. These inherent defects are less pronounced in single-layer embroidery and can be controlled appropriately by skilled operators, so they are still within acceptable limits for single-layer embroidery, but are significantly exaggerated in severity if double-layer embroidery is employed.

Therefore, in order to better perform double-layer embroidery, the applicant has previously made improvements on the existing cloth clamping means based on the above, and added the inner frame 3 similar to the tabouret 11 and the matched combined clamp. The inner frame 3 is a frame arranged at the inner ring of the embroidery frame 1, can be an integral frame, can also be a single side rail, and is provided with a part for clamping the embroidery material clamp 5 like the embroidery frame 11; the combined clamp comprises a plate body with a handle, and the lower part of the plate body is connected with two embroidery clamps 5. The embroidery frame 1 and the embroidery material clamp 5 clamp the bottom embroidery material, the inner frame 3 and the embroidery material clamp 5 clamp the upper embroidery material, and the combined clamp is used for clamping the embroidery frame 1 and the inner frame 3 together, so that the upper and lower embroidery materials can be clamped, stacked and separated, and the figure 1 can be referred. When double-layer embroidery is performed, the bottom-layer embroidery material is still clamped and fixed with the embroidery material clamp 5 through the embroidery frame 1, the upper-layer embroidery material is clamped and fixed with the embroidery material clamp 5 through the inner frame 3, and then the embroidery frame 1 and the inner frame 3 are clamped simultaneously through the combined clamp. However, the applicant finds that the method still has great defects in the actual production industry, and the method mainly comprises the following points: firstly, when the embroidery frame 1 and the inner frame 3 are frequently loosened and fixed by the combined clamp, the inner frame 3 is clamped and fixed only by the elastic characteristic of the embroidery clamp 5, the bent clamping piece structure of the embroidery clamp 5 is axially through, the two ends of the bent clamping piece structure are not provided with blocking structures, the embroidery clamp 5 is easy to rotate in the radial direction, so that the inner frame 3 is easy to relatively move transversely and deflect, the upper embroidery layer and the lower embroidery layer are easy to misplace, and finally the obtained embroidery is unqualified; secondly, after the pattern is embroidered in the middle of the upper-layer embroidery material, the periphery of the embroidery material can contract towards the position of the pattern in the middle, the tension changes along with the contraction, when the combined clamp is used for fixing, the inner frame 3 needs to be pulled by hands forcefully to be close to the embroidery frame 1, and then the combined clamp is pressed downwards and clamped on the embroidery frame 1 and the inner frame 3, so that the operation is very laborious, the combined clamp is difficult to align and clamp, certain potential safety hazards exist, the structure is easy to damage, and even the structure is easy to damage to a worker per se; thirdly, even after the combined clamp was held, because the dead weight of inside casing 3 and the centre gripping mode self of combined clamp have the shortcoming of easily taking place radial rotation, inside casing 3 can be for tabouret 1 is the state of "drooping", also namely inside casing 3 can oppress on lower floor's embroidery material, the embroidery in-process framework all need remove, this just makes easily in the course of the work, lower floor's embroidery material can be rubbed by inside casing 3 constantly, mostly is pressed and rubs on the mesa face, thereby lead to lower floor's embroidery material impaired.

The embodiment of the present invention refers to the content included in a set of more complete solutions discovered by thinking and multiple practices after the applicant frequently encounters and finds the aforementioned problems by using experience of years in the embroidery industry, and can refer to fig. 3, 4, 5 and 6, in particular to a frame system for clamping an embroidery material clamp 5 applied to multilayer embroidery, which comprises an embroidery frame 1, an auxiliary clamp 2 and a tensioning assembly; an tabouret inner side clamping surface 11 is arranged on the tabouret 1; the auxiliary clamp 2 is provided with a clamp front side clamping surface 21 and a rear side embroidery material clamping crosspiece 22, the clamp front side clamping surface 21 is used for being matched and tightly attached with the embroidery frame inner side clamping surface 11 to clamp embroidery materials, and the rear side embroidery material clamping crosspiece 22 is used for being matched with the embroidery material clamp 5 to clamp embroidery materials; the tabouret 1 and the matched auxiliary clamping piece 2 correspond to a tensioning assembly, and the auxiliary clamping piece 2 is pulled to the tabouret 1 by the tensioning assembly until the auxiliary clamping piece and the tabouret are tightly attached and fixed. The auxiliary clip 2 can completely replace the old embroidery clip 5 and still cooperate with the embroidery clip 5, while the cloth clamping effect effectively eliminates the defects with respect to the known methods.

When single-layer embroidery is carried out, the embroidery edge is clamped by the inner clamping surface 11 of the embroidery frame and the front clamping surface 21 of the clamping piece 2 of the embroidery frame, the auxiliary clamping piece 2 is pulled towards the embroidery frame by the tensioning assembly until the auxiliary clamping piece 2 and the embroidery frame are tightly attached and fixed, specifically, one part of the tensioning assembly is connected to the embroidery frame 1, the other part of the tensioning assembly is connected to the auxiliary clamping piece 2, one part of the two parts can drive the connected body to move relatively, the auxiliary clamping piece 2 is pulled straightly towards the direction of the embroidery frame 1, so that the front clamping surface 21 of the clamping piece is tightly attached to the inner clamping surface 11 of the embroidery frame, and then the clamping assembly is locked by the locking structure of the clamping assembly, the tensioning state is kept, and the tensioning assembly can be realized by utilizing an air cylinder, a spring, a pressing type lock; in the double-layer embroidery, the lower-layer embroidery material clamp 5 is fixed according to the single-layer embroidery operation, and then the upper-layer embroidery material is clamped by the rear-side embroidery material clamping crosspiece 22 and the embroidery material clamp 5.

In yet another implementation manner of double embroidery, in particular, the auxiliary clamp 2 is optionally additionally provided with a rear embroidery clamping surface 24, the rear embroidery clamping surface 24 and the front clamping surface 21 of the clamp can be fitted tightly in shape so as to enable two adjacent auxiliary clamps 2 to be butted back and forth, the two auxiliary clamps 2 correspond to a tensioning assembly, the two auxiliary clamps 2 are tensioned and fixed by the tensioning assembly, at this time, one part of the tensioning assembly is connected to the previous auxiliary clamp 21, the other part of the tensioning assembly is connected to the next auxiliary clamp 2, one part of the two parts can carry the bodies of the connected auxiliary clamps 2 to perform relative movement, one auxiliary clamp 2 is pulled straightly towards the other auxiliary clamp 2, so that the front clamping surface 21 of the clamp is tightly attached to the rear clamping surface 24 of the clamp, and then the clamping is locked by a locking structure provided by the auxiliary clamps to keep the tensioning state, the tensioning assembly can also be implemented with cylinders, springs, press-fit latches, bolts, etc. That is, the upper embroidery material can be clamped and fixed by the two auxiliary clamping pieces 2 and the other tensioning assembly. Therefore, it is easy to understand that the auxiliary clamps 2 can clamp three, four or more layers of embroidery materials to realize multi-layer embroidery when the rear-side embroidery material clamping surface 24 is additionally arranged.

According to the scheme, the self elastic deformation is not utilized like an embroidery clamp 5 to clamp the embroidery material in a self-buckling manner, but the auxiliary clamp 2 is pulled in the straight direction to clamp the embroidery material by virtue of a tensioning assembly with a simple or complex structure through the auxiliary clamp 2, so that the operation is easy and convenient, and the problem that the auxiliary frame is difficult to clamp after being pulled by hands like a combined clamp; the auxiliary clamping piece 2 is a clamping medium, when the clamping assembly is disassembled, the auxiliary clamping piece 2 does not clamp the embroidery materials any more as long as the tensioning assembly is switched from a locking state to a loosening state, so that the auxiliary clamping piece 2 cannot cause pulling damage to the embroidery materials in actual operation; when the auxiliary clamping piece 2 is straightly tensioned by the tensioning assembly, the fastening effect is very stable, the phenomenon that the clamp bounces off is not easy to occur, and the phenomenon that the auxiliary clamping piece 2 deflects and presses the lower-layer embroidery material by 'drooping' on the side close to the inner part of the auxiliary clamping piece or the lateral movement is generated in the axial direction like a combined clamp can be avoided, so that the embroidery precision and the embroidery quality are ensured.

The following description will be made by taking the fitting of the embroidery frame 1 and the auxiliary clip 2 as an example. Further, in order to achieve better effect, one or more station stabilizing blocks 23 are fixedly connected to the top surface of the auxiliary clamp 2, and referring to fig. 3 and 4, a leaning bottom surface for pressing against the top surface of the embroidery frame 1 is arranged on the station stabilizing block 23, and the leaning bottom surface is used for keeping the bottom surface of the auxiliary clamp 2 flat without pressing the lower-layer embroidery material after the auxiliary clamp 2 is tensioned and fixed.
