Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1, a preferred embodiment of a cloth clamping device for a high-precision embroidery machine, in this embodiment, the cloth clamping device for the high-precision embroidery machine includes two clamping members respectively disposed at left and right side edge positions of a working position of the embroidery machine to fix and tighten a corresponding cloth 1 at both sides of the working position of the embroidery machine.

The two clamping components of the embodiment are oppositely arranged and respectively comprise an inner lining pipe and a sleeve pipe, wherein the inner lining pipe comprises a metal outer pipe 5 and an expansion sleeve 6, through holes 8 shown in figure 2 are formed in the metal outer pipe 5, the through holes 8 are irregular triangular holes and are irregularly arranged on the metal outer pipe 5, the ratio of the corresponding bottom edge of each triangular hole to the height of the triangular hole is kept within the ratio range value of 3: 1-4: 1, the length of the corresponding bottom edge of the triangular hole of each through hole 8 is 1/8 of the height of the working position of the embroidery machine, and the angle of the corresponding vertex of the triangular hole of each through hole 8 is an outward convex edge and faces the tensioning direction of the clamping components; the expansion sleeve 6 is lined on the inner side of the metal outer pipe 5, and surface bulges matched with the through holes are formed at the positions corresponding to the through holes 8. Meanwhile, the rubber bushing 4 is sleeved on the outer surface of the metal outer pipe 5, the contact area of the surface bulge of the expansion sleeve 6 corresponding to the through hole 8 and the cloth 1 under the inflation condition can be effectively increased through the arrangement of the rubber bushing 4, the clamping degree is improved, and meanwhile, the abrasion is reduced; the rubber bushing 4 is of a detachable sleeving structure, and can effectively improve the abrasion and aging interval of the surface of the lining pipe and prolong the service life of the lining pipe through dismounting.

In this embodiment, the sleeve pipe includes sleeve pipe body 2, and this sleeve pipe body 2 is the elasticity body, and the shaping has detachable epoxy inside lining 3 simultaneously on the medial surface of this sleeve pipe body 2, and this epoxy inside lining 3's the shaping has anomalous arc protruding on the surface, and these arc are protruding and epoxy inside lining 3 for with material integrated into one piece, and the protrusion height is 1.5~2 mm.

And a central inflation tube 7 is arranged at the axis position of the lining tube, and the end surface of the central inflation tube 7 is externally connected with an air source. When feeding, firstly ensuring the expansion sleeve 6 to be in a pressure relief state, at the moment, a gap is formed between the epoxy resin lining 3 and the rubber bushing 4, inserting the cloth 1 into a proper position in the gap, then starting an external air source connected with the expansion sleeve 6, enabling the expansion sleeve to form an outward bulge at a surface convex position of the through hole 8 through the air pressure change in the expansion sleeve 6, enabling the rubber bushing 4 to be abutted against the epoxy resin lining 3 on the inner side of the sleeve pipe body 2, enabling the cloth 1 clamped between the epoxy resin lining 3 and the rubber bushing 4 to be in friction locking, and then rotating the clamping components to enable the cloth 1 to be in a tightening state between the two clamping components to carry out embroidery processing; when the cloth is loosened, the cloth 1 which is tightened is loosened only by rotating the clamping assembly, then the air pressure in the expansion sleeve 6 is reduced, a gap can be generated between the epoxy resin lining 3 and the metal outer pipe 5, and at the moment, the cloth 1 is pulled out.

In another embodiment, the number of the clamping components is four, and the four clamping components are respectively arranged at the upper, lower, left and right outer side edge positions corresponding to the working position of the embroidery machine; meanwhile, the through holes 8 on the surface of the metal outer pipe 5 are in a regular lattice arrangement as shown in fig. 3, each through hole 8 comprises a straight edge and an outer convex arc edge, the straight edges are parallel to the axis of the inner lining pipe, the length of each through hole is 1/5-1/6 of the height/width of the working position of the embroidery machine, two ends of each outer convex arc edge are respectively connected with two ends of each straight edge to form an arc section, and the outer convex arc edge of each arc section faces the tensioning direction of the clamping component. The clamping assembly in this way can further improve the stability of clamping the cloth 1 through four-side positioning and prevent edge leakage, and although the arrangement of the friction force of the arrangement form of the through holes 8 is weaker than that of the through hole structure of the embodiment shown in fig. 2, the arrangement form has the advantages that the processing and the arrangement of the expansion sleeve 6 and the metal sleeve 5 are convenient, and the cost can be effectively reduced.
