Description

Technical Field

[0001] The utility model relates to an embroidery frame and an embroidery machine, belonging to the technical field of embroidery machines. Background Art

[0002] In the prior art, a lower reinforcing plate is provided on the bottom surface of the four corner portions of the embroidery frame. The lower reinforcing plate is fixedly connected to the corner portions of the embroidery frame by fasteners. The embroidery frame is usually made of aluminum alloy, which has relatively weak strength. Since the fasteners are fixedly connected to the corner portions of the embroidery frame, the fasteners do not have sufficient locking force on the embroidery frame. In addition, the fasteners are fixedly connected to the embroidery frame in the form of points. The embroidery frame is usually made of aluminum alloy, which has relatively weak strength. As a result, the stress of the fasteners on the corner portions is relatively concentrated, which makes the fasteners easy to loosen and the embroidery frame easy to be damaged.

[0003] In addition, when the embroidery frame is driven, the power of the driving motor is first transmitted to the right or left gear, and then transmitted to the front and rear gears through the right or left gear. The front and rear gears of the frame are long. When the embroidery frame reciprocates at high speed in the X / Y direction, it is very easy for the embroidery frame to be broken or damaged.

[0021] The present invention will be described in further detail below based on the accompanying drawings and implementation examples.

[0022] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0023] Implementation Case 1:

[0024] An embroidery frame, referring to Figure 1-Figure 4 The front and rear guards 11, 12, 13, 14, and the X-type auxiliary guard 15 are shown. These guards form a frame structure with four corners 16 formed at each of the four corners. The front and rear guards 11, 12 extend in the X direction, while the left and right guards 13, 14, and the X-type auxiliary guard 15 extend in the Y direction. The X-type auxiliary guard 15 is located outside the left and / or right guards 13, 14. The left and / or right guards 13, 14 are fixedly connected to an X-type sliding carriage 3, which is slidably connected to the X-type auxiliary guard 15.

[0025] In this embodiment, an upper reinforcing plate 21 is provided on the top surface of the angled portion 16, and a lower reinforcing plate 22 is provided on the bottom surface of the angled portion 16. The upper and lower reinforcing plates 21 and 22 are stronger than the embroidery frame, which is typically made of aluminum alloy, while the upper and lower reinforcing plates 21 and 22 are made of steel. The upper reinforcing plate 21, the angled portion 16, and the lower reinforcing plate 22 are fixedly connected by a plurality of fasteners extending through them, so that the upper and lower reinforcing plates 21 and 22 clamp the angled portion 16.

[0026] In this embodiment, the upper reinforcing plate 21 and the lower reinforcing plate 22 clamp the corner portion 16, and the three are fixedly connected by fasteners, thereby increasing the contact area between the reinforcement structure (the upper reinforcing plate 21 and the lower reinforcing plate 22) and the embroidery frame, improving the reliability of the fixed connection, and avoiding the fasteners from fixing the corner portion 16 in the form of points, avoiding the situation where the fasteners cause excessive stress concentration on the corner portion 16, thereby effectively enhancing the structural strength of the corner portion 16 and avoiding the embroidery frame from being damaged at the corner portion 16.

[0027] In this embodiment, the bottom surface of the front block 11 / the rear block 12 is provided with a slide rail 17 extending along its length direction. The slide rail 17 is used to slideably connect the Y sliding trolley 4, and the slide rail 17 extends into the lower reinforcing plate 22.

[0028] In this embodiment, the structural strength of the slide rail 17 is also greater than that of the embroidery frame, and is usually made of steel. By extending the slide rail 17 to the lower reinforcement plate 22, the extension range of the lower reinforcement plate 22 is extended, thereby extending the range of the embroidery frame to which the structural reinforcement portion is attached.

[0029] In this embodiment, the slide rail 17 is fixedly connected to the bottom surface of the front guard 11 / rear guard 12 by fasteners.

[0030] In this embodiment, the lower reinforcing plate 22 has an avoidance groove 221 extending along the length direction of the slide rail 17 , and a portion of the slide rail 17 extends into the avoidance groove 221 .

[0031] In this embodiment, there are multiple slide rails 17 set on the bottom surface of the front block 11 / the rear block 12, and they are arranged intermittently with each other. The slide rail 17 extends into the avoidance groove 221. Since the part of the slide rail 17 extending into the avoidance groove 221 cannot be slidably connected to the Y sliding trolley 4, the total length of the slide rail 17 is greater than the stroke length of the embroidery frame sliding along the direction of the slide rail 17 to match the movement stroke of the embroidery frame along the X direction.

[0032] In this embodiment, the X-sliding trolley 3 is fixedly connected to the lower reinforcing plate corresponding to the left gear and / or the right gear.

[0033] In this embodiment, the X-shaped sliding carriage 3 includes a main body 31 and an adjustment portion 32. The main body 31 is provided with at least one first roller 33, and the adjustment portion 32 is provided with at least one second roller 34. The bottom surface of the X-shaped auxiliary gear 15 has two rails 151 extending along its extension direction and spaced apart from each other. The main body 31 is fixedly connected to the lower reinforcing plate 22 via fasteners. The first roller 33 is slidably connected to one of the rails 151. The adjustment portion 32 is connected to the main body 31 or the lower reinforcing plate 22 in the same manner as the main body 31, also via fasteners. The adjustment portion 32 can be adjusted to change the spacing between the first roller 33 and the second roller 34. The second roller 34 is slidably connected to the other rail 151. The adjustment portion 32 can adjust the spacing between the first roller 33 and the second roller 34, thereby ensuring a stable and reliable sliding connection between the X-shaped auxiliary gear 15 and the X-shaped auxiliary gear 15.

[0034] In this embodiment, the through hole a in the upper reinforcing plate 21 through which the fastener passes is configured as a countersunk hole to reduce the height of the fastener's tip. More specifically, the fastener is configured as a countersunk screw. By providing a countersunk hole to reduce the height of the fastener's tip, interference and collision between the fastener and other components of the embroidery machine can be avoided.

[0035] Implementation Case 2:

[0036] An embroidery machine includes an embroidery frame, and the embroidery frame is shown in Implementation Case 1.

[0037] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the utility model.
