[0032] like Figures 1 to 5 As shown, a modular quick-release pneumatic inner frame for an embroidery machine is a detachable inner frame 1. Fabric is fixed to the detachable inner frame 1, which is installed on the embroidery machine frame 1. The embroidery machine frame 1 includes a front frame 3A and a rear frame 3B. A quick-release device for the embroidery machine frame inner frame is used to achieve quick fixing and detachment of the detachable inner frame 1 from the embroidery machine frame 1. This quick-release device includes:

[0033] Detachable inner frame 1: The detachable inner frame 1 is a rectangular frame, including an inner frame front panel 11, an inner frame rear panel 12, and inner frame side panels 13 on the left and right sides. The detachable inner frame 1 is fixedly connected to the inner frame front panel 11 and inner frame rear panel 12 at the corner connection points by an inner frame fixing angle ruler 14 and fixing screws.

[0034] Inner frame rear window quick-release assembly 2B: The inner frame rear window quick-release assembly 2B includes an inner frame rear window connecting plate 25B, an inner frame rear window pressure plate 22B, and a rear window pneumatic component 24B. The inner frame rear window connecting plate 25B connects the inner frame rear window 12 and the frame rear window 3B. The inner frame rear window pressure plate 22B is hinged to the inner frame rear window connecting plate 25B. The inner frame rear window pressure plate 22B is driven by the rear window pneumatic component to press and fix the inner frame rear window 12 to the frame rear window 3B.

[0035] Inner frame front windshield quick-release assembly 2A: The rear side of the frame front windshield 3A is provided with a front windshield fixing groove, and the front side of the inner frame front windshield 11 is provided with a front windshield fixing edge 111. The front windshield fixing edge 111 is inserted into the front windshield fixing groove, and a front windshield pneumatic component is provided in the front windshield fixing groove to press and fix the front windshield fixing edge 111.

[0036] The front and rear frames 3A and 3B of the frame are provided with a cylindrical protrusion 31 on one side edge of the detachable inner frame 1, and a groove 32 is provided in contact with the cylindrical protrusion 31. On the front frame 3A, the groove 32 serves as a front frame fixing groove. The front side of the inner frame front 11 is provided with an inverted U-shaped part, and the front side edge of the inverted U-shaped part serves as a front frame fixing stop 111. The rear side of the inner frame rear 12 is provided with a cylindrical body 121, and the bottom surface of the cylindrical body 121 is flat. The upper part of the cylindrical body is provided with an arc-shaped section, preferably a serrated surface.

[0037] In one embodiment, the windshield pneumatic component includes a windshield airbag 25A and an airbag pressure plate 26A driven by the windshield airbag 25A and pressed against the windshield fixed flange 111.

[0038] To facilitate the removal of the inner frame front windshield 11, the inner frame front windshield quick removal assembly also includes a front windshield spring plate 24A that drives the airbag pressure plate 26A to leave the front windshield fixed edge 111 after the front windshield airbag 25A is depressurized.

[0039] Furthermore, such as Figure 5 As shown, the inner frame windshield quick-release assembly also includes an upper windshield pressure plate 22A and a lower windshield pressure plate 23A. The windshield spring plate 24A includes a horizontal portion 241A that clamps and fixes between the upper windshield pressure plate 22A and the lower windshield pressure plate 23A. The windshield spring plate 24A also includes a bent portion 242A that bends backward from the horizontal portion 241A and presses against the airbag pressure plate 26A. When the windshield airbag 25A is not inflated, the bent portion 242A applies an elastic force to the airbag pressure plate 26A and compresses the windshield airbag 25A. After the windshield airbag 25A is inflated, it drives the airbag pressure plate 26A to resist the elastic force of the bent portion 242A on the airbag pressure plate 26A and presses against the windshield fixing edge 111.

[0040] To facilitate the installation of the upper windshield pressure plate 22A and the lower windshield pressure plate 23A, the rear end of the lower windshield pressure plate 23A is provided with a downwardly extending L-shaped flange 231A, which mates with the front sidewall of the windshield fixing groove. The bottom surface of the upper windshield pressure plate 22A is provided with a stepped surface that convexes downward on the front side and acts on the horizontal portion 241A of the windshield spring plate, and is spaced apart from the horizontal portion 241A of the windshield spring plate on the rear side. The rear end of the upper windshield pressure plate 22A is provided with a downwardly bent rear vertical flange 221A that acts on the bent portion 242A, and the front end of the upper windshield pressure plate 22A is provided with a downwardly bent front vertical flange 222A. Due to the design of the stepped surface of the bottom of the front windshield upper pressure plate 22A, the rear side of the horizontal part 241A of the front windshield spring has elastic deformation space, and at the same time, the rear vertical fold 221A restricts the bending part 242A of the front windshield spring. In this way, after the front windshield airbag 25A is depressurized, the bending part 242A of the front windshield spring drives the airbag pressure plate 26A to leave the front windshield fixed edge 111.

[0041] In order to position the left and right sides between the inner frame front guard 11 and the frame front guard 3A, the inner frame front guard 11 is provided with a front guard limiting groove, and the frame front guard 3A is fixed with a front guard limiting block 21A that cooperates with the front guard limiting groove.

[0042] like Figure 4As shown, in this embodiment, the inner frame rear panel connecting plate 25B includes a hinge portion 251B that is hinged to the inner frame rear panel pressure plate 22B, and a front extension bottom edge 252B that extends horizontally from the front bottom of the hinge portion 251B to the front side. The bottom surface of the cylindrical body 121 on the rear side of the inner frame rear panel is supported on the front extension bottom edge 252B.

[0043] Furthermore, the inner frame rear stop connecting plate 25B also includes a pneumatic component mounting part 253B located above the hinge part 251B for mounting the rear stop pneumatic component, and a rear extension top edge 254B extending horizontally from the pneumatic component mounting part 253B to the rear side. The rear lower side of the rear extension top edge 254B is provided with a rear positioning stop edge 255B that is positioned and cooperates with the rear stop 3B of the frame, specifically cooperating with the rear side wall top edge of the groove 32 on the rear stop 3B of the frame.

[0044] The rear window pneumatic component 24B is also an airbag, and the pneumatic component mounting part 253B is provided with an airbag mounting groove. In order to facilitate the removal of the inner frame rear window 12, the inner frame rear window quick removal assembly also includes a return spring 23B that connects the inner frame rear window connecting plate 25B and the inner frame rear window pressure plate 22B.

[0045] To install the return spring 23B, the inner frame rear stop connecting plate 25B has a vertical mounting hole. One end of the return spring 23B has a first support leg 231B that bends vertically upwards, and the first support leg 231B is inserted into the vertical mounting hole. The inner frame rear stop pressure plate 22B has a rectangular tube 222B, and the other end of the return spring has a second support leg 232B that bends in a V-shape, and the second support leg 232B is elastically supported inside the rectangular tube. Correspondingly, the hinge part 251B and the rectangular tube 222B have return spring through holes.

[0046] Furthermore, the hinge portion 251B is provided with a circular groove with an arc-shaped opening, and the inner frame rear retaining plate 22B is provided with a rotating shaft 221B, which is rotatably connected to the circular groove. The inner frame rear retaining plate 22B is provided with an arc-shaped pressure head 223B that presses against the upper arc-shaped section of the cylindrical body to form a good fit and ensure sufficient clamping force.

[0047] In order to position the left and right sides between the inner frame rear section 12 and the frame front section 3B, the inner frame rear section 12 is provided with a rear section limiting groove, and the frame rear section 3B is fixed with a rear section limiting block 21B that cooperates with the rear section limiting groove.

[0048] refer to Figure 6 and Figure 7As shown, during installation, the rear panel 12 of the inner frame is inserted between the rear panel pressure plate 22B and the rear panel connecting plate 25B of the inner frame. At the same time, the rear panel limiting block 21B limits the left and right directions. After the rear panel 12 of the inner frame is positioned, the front panel 11 of the inner frame is pressed down and pushed into the front panel fixing groove of the front panel 3A of the frame. At this time, there is still a gap between the front panel fixing edge 111 of the front panel 11 of the inner frame and the airbag pressure plate 26A. At the same time, the front panel limiting block 21A is limited and constrained by the front panel limiting groove on the left and right. At this time, the detachable inner frame has been placed in the predetermined position.

[0049] Then, the airbag solenoid valve is opened by the control computer to inflate the airbag. The front airbag 25A inflates and pushes the airbag pressure plate 26A to press against the front fixed edge 111 of the inner frame front guard 11, fixing it to the frame front guard 3A. At the same time, the rear airbag also inflates and pushes the inner frame rear guard pressure plate 22B. Since the inner frame rear guard pressure plate 22B and the inner frame rear guard connecting plate 25B are connected by a joint mechanism, the inner frame rear guard pressure plate 22B can be flipped downwards to press against the inner frame rear guard 12, fixing it to the frame rear guard 3B of the embroidery machine frame.

[0050] By using the aforementioned quick-release device for the inner frame of the embroidery machine, the fixed time for each piece of fabric on the embroidery machine is shortened to about 45 seconds, and the machine only needs to be stopped for about 45 minutes, which greatly simplifies manual operation and improves production efficiency.
