Description

Technical Field

[0001] This utility model generally relates to the field of computerized embroidery machine technology, and more particularly to an embroidery frame and a computerized embroidery machine. Background Technology

[0002] In the field of computerized embroidery machine technology, the frame of an embroidery machine is generally equipped with a frame crossbar. The frame crossbar is parallel to the front and rear rails of the frame and can move back and forth. When embroidering fabrics of different widths, the front and rear positions of the crossbar are adjusted to clamp the fabric. Currently, the frame crossbar and the left and right rails are fixed by clamps. There are fixed clamps at both ends of the frame crossbar. After adjusting the front and rear positions of the frame crossbar according to the width of the fabric, tighten the clamp screws, and the clamps will hold the fabric in place by the left and right rails.

[0003] However, the above method has drawbacks: when a computer embroidery machine is embroidering, the frame and the frame crossbar are constantly moving left, right, forward and backward, accelerating and decelerating. The fastest embroidery machine currently has a speed of 1500 revolutions per minute, so the frame has to accelerate and decelerate up to 1500 times per minute. The frame crossbar clamp is easy to loosen. Once it loosens, it will affect the quality of the embroidery and may even damage the embroidery machine. Utility Model Content

[0004] This application aims to provide an embroidery frame and a computerized embroidery machine, which at least avoids using clamping blocks to clamp the fabric clamping protrusions on the left or right frame, so that the structure of the fabric clamping protrusions is not damaged, which helps to extend the service life of the fabric clamping protrusions and ensure the clamping effect.

[0005] This utility model provides an embroidery frame, including: a frame body, a crossbar, and connecting parts.

[0006] The main frame is a rectangular frame, and the main frame has a plurality of second through holes arranged in the same direction; the crossbar is located inside the rectangular frame, and the end of the crossbar has a first through hole; the connector moves along the arrangement direction of the second through holes to a preset second through hole, the connector is connected to the main frame through the preset second through hole, and the connector is connected to the crossbar through the first through hole.

[0007] As one possible implementation, the connector includes a first plate and a second plate, the first plate being parallel to the crossbar, and the second plate being parallel to the arrangement direction of the second through holes.

[0008] The first plate has a first connecting hole, one of which is a circular hole and the other is an elongated hole; the second plate has a second connecting hole, one of which is a circular hole and the other is an elongated hole.

[0009] As an alternative implementation, a first stop and a second stop are also included.

[0010] The main frame includes four side frames connected end-to-end. Each side frame and each crossbar is made of hollow aluminum profile. Each crossbar has a crossbar cavity extending along its length, and each side frame has a side frame cavity extending along its length. A first stop is disposed within a crossbar cavity, and a first fastener passes through the first connecting hole and the first through hole and is threadedly connected to the first stop. A second stop is disposed within one of the side frame cavities, and a second fastener passes through the second connecting hole and the second through hole and is threadedly connected to the second stop.

[0011] As an implementation method, both the first connecting hole and the second connecting hole are elongated holes.

[0012] As an implementation method, the second plate is provided with a plurality of second connecting holes that are equally spaced along the same direction, the distance between two adjacent second connecting holes is L2, the length of the second connecting hole is L1, the second through holes are arranged at equal intervals, the distance between two adjacent second through holes is L3, and L2≤L3≤L1.

[0013] As an alternative implementation, a reinforcing member is also included. The length extension direction of the reinforcing member is perpendicular to the length extension direction of the crossbar, and the reinforcing member is disposed between the crossbar and the frame, connecting the two. The reinforcing member includes a rectangular tube and a long strip plate arranged in parallel, and the rectangular tube and the long strip plate are integrally formed and connected.

[0014] As an implementation method, the width of the rectangular tube is smaller than the width of the long strip. In the width direction of the long strip, the rectangular tube is located in the middle of the long strip. Several third connecting holes are provided in the areas on both sides of the long strip located in the width direction of the rectangular tube. Each of the third connecting holes is arranged at intervals along the length direction of the long strip.

[0015] As an alternative implementation, an adjusting member is also included. The adjusting member is detachably connected to the reinforcing member, threadedly connected to the crossbar, and its position can be adjusted along the length of the crossbar so that the reinforcing member is perpendicular to the crossbar.

[0016] The adjusting member is threadedly connected to the frame and its position can be adjusted along the length of the frame so that the reinforcing member is perpendicular to the crossbar.

[0017] This utility model also provides a computerized embroidery machine, including the embroidery frame described above.

[0018] In the above solution, the connector is connected to the frame body through a second through hole selected from several second through holes, either near or far from the rear frame; the connector is connected to the crossbar through a first through hole. This allows for adjustment of the distance between the crossbar and the rear frame, or between the crossbar and the front frame, to accommodate fabrics of different sizes.

[0036] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] At least see Figures 1-10 As shown, this utility model provides an embroidery frame that is applied to a computerized embroidery machine.

[0039] The embroidery frame includes a frame body 10, a horizontal bar 20, and a connector 30. The frame body 10 is a rectangular frame, and has several second through holes 121 arranged at equal intervals along the same direction. The horizontal bar 20 is located inside the rectangular frame, and has a first through hole 21 at its end.

[0040] The connector 30 moves along the arrangement direction of the second through hole 121 to the preset second through hole 121. The connector 30 is connected to the frame body 10 through the preset second through hole 121, and the connector 30 is connected to the crossbar 20 through the first through hole 21.

[0041] Among them, such as Figure 1 and Figure 2 As shown, the main frame 10 includes a front frame 11, a left frame 14, a rear frame 13, and a right frame 12 connected end to end. The front frame 11, left frame 14, rear frame 13, and right frame 12 form a rectangular frame. A horizontal bar 20 is located inside the rectangular frame and extends in the left-right direction. The horizontal bar 20 is set parallel to the front frame 11 or the rear frame 13.

[0042] like Figure 3 As shown, the end of the crossbar 20 is provided with a first through hole 21. At least one of the left frame 14 and the right frame 12 is provided with a plurality of second through holes 121 arranged at equal intervals along its length. The connector 30 is connected to the frame body 10 by selecting a second through hole 121 that is close to or far from the rear frame 13; the connector 30 is connected to the crossbar 20 through the first through hole 21.

[0043] This design allows for adjustment of the distance between the horizontal bar 20 and the rear frame 13, or between the horizontal bar 20 and the front frame 11, to accommodate fabrics of different sizes. Furthermore, it avoids using clamping blocks to clamp the fabric clamping protrusions 123 on the left frame 14 or right frame 12, thus preventing damage to the structure of the fabric clamping protrusions 123, extending their service life, and ensuring effective fabric clamping.

[0044] In one possible implementation, the connector 30 includes a first plate 31 and a second plate 32. The first plate 31 is parallel to the crossbar 20, and the second plate 32 is parallel to the arrangement direction of the second through holes 121. The first plate 31 has a first connecting hole 311, one of which, the first connecting hole 311, is a circular hole, and the other is an elongated hole. The second plate 32 has a second connecting hole 321, one of which, the second connecting hole 321, is a circular hole, and the other is an elongated hole.

[0045] like Figure 3 As shown, the connector 30 is plate-shaped and has a clearance notch 33 to form a first plate 31 and a second plate 32. The clearance notch 33 is used to avoid the corner plate 70 at the junction of the two side frames.

[0046] The first plate 31 extends horizontally and is parallel to the crossbar 20. The second plate 32 extends front-back and is parallel to the right side frame 12 and the left side frame 14. The first plate 31 has a first connecting hole 311 that mates with the first through hole 21; the first connecting hole 311 is an elongated hole. The second plate 32 has a second connecting hole 321 that mates with the second through hole 121; the second connecting hole 321 is also an elongated hole.

[0047] like Figure 4 and Figure 5 As shown, the front frame 11, left frame 14, rear frame 13, right frame 12, and crossbar 20 are all hollow aluminum profiles. The frame has a frame cavity 122 extending along its length direction, and the crossbar 20 has a crossbar cavity 22 extending along its length direction.

[0048] The embroidery frame also includes a first stop 41 disposed in the crossbar cavity 22 and a second stop 42 disposed in the frame cavity 122. The first stop 41 and the second stop 42 are elongated strips, and both the first stop 41 and the second stop 42 are provided with threaded holes.

[0049] The connector 30 is connected by selecting one of the second through holes 121 that is close to or far from the rear frame 13, such as... Figure 5 As shown, the first bolt passes through the second connecting hole 321 and the second through hole 121, and is threadedly connected to the second stop 42. This achieves a stable connection between the second plate 32 and the left frame 14 or the right frame 12, keeping the crossbar 20 stationary relative to the frame body 10. Correspondingly, as... Figure 4 As shown, the second bolt passes through the first connecting hole 311 and the first through hole 21, and is threadedly connected to the first stop 41. This achieves a stable connection between the first plate 31 and the crossbar 20, so that the crossbar 20 remains stationary relative to the frame body 10.

[0050] In addition, a gasket is sandwiched between the first plate 31 and the crossbar 20.

[0051] In practical applications, in order for the horizontal bar 20 to move to any position within the full travel of the left border 14 or the right border 12—that is, for the horizontal bar 20 to move continuously in the front-back direction—the working area size D formed between the horizontal bar 20 and the front border 11 can continuously change. Figure 6 and Figure 7 As shown.

[0052] like Figure 3 As shown, the first plate 31 has several first connecting holes 311 arranged at equal intervals along the left-right direction. The second plate 32 has several second connecting holes 321 arranged at equal intervals along the front-back direction. The second connecting holes 321 are elongated holes. The distance between two adjacent second connecting holes 321 is L2, and the length of the second connecting hole 321 is L1. The distance between two adjacent second through holes 121 is L3. L2≤L3≤L1.

[0053] As one possible implementation, the first plate 31 and the second plate 32 are arranged in an L-shape. For example... Figure 7 and Figure 8 As shown, this allows the connector 30 to be used in both directions. When used in both directions, the adjustable crossbar 20 can move its travel in the front-to-back direction, thereby changing the working area size D.

[0054] As an alternative implementation, the embroidery frame also includes a reinforcing member 50. The length extension direction of the reinforcing member 50 is perpendicular to the length extension direction of the crossbar 20, and the reinforcing member 50 is disposed between the crossbar 20 and the frame, connecting the two.

[0055] The reinforcing member 50 includes a rectangular tube 51 and a long strip 52 arranged in parallel. The width of the rectangular tube 51 is smaller than the width of the long strip 52. The rectangular tube 51 and the long strip 52 are integrally formed and connected.

[0056] like Figure 9 As shown, the reinforcing member 50 is elongated, extending along its length in the front-to-back direction, and is perpendicular to the crossbar 20. The reinforcing member 50 can be located between the crossbar 20 and the rear frame 13, or between the crossbar 20 and the front frame 11, connecting the two. The following embodiment uses the reinforcing member 50 located between the crossbar 20 and the rear frame 13.

[0057] The reinforcing member 50 includes a rectangular tube 51 and a long strip 52 arranged in parallel. In the width direction of the long strip 52, the rectangular tube 51 is located in the middle of the long strip 52. Several third connecting holes 521 are provided on both sides of the long strip 52 in the width direction of the rectangular tube 51, and the third connecting holes 521 are spaced apart along the length direction of the long strip 52. For example... Figure 9 As shown, one fastener passes through the third connecting hole 521 on the long strip 52 near the crossbar 20 and is connected to the crossbar 20 through the first pad. Another fastener passes through the third connecting hole 521 on the long strip 52 near the rear frame 13 and is connected to the rear frame 13 through the second pad.

[0058] The reinforcement 50 ensures that the crossbar 20 remains stationary relative to the frame body 10. Meanwhile, because the rectangular tube 51 is structurally stable and has a high load-bearing capacity, its integral connection with the long strip 52 improves the strength, rigidity, and stability of the reinforcement 50, further ensuring that the crossbar 20 remains stationary relative to the frame body 10.

[0059] In practical applications, due to the manufacturing process, the first pad and the second pad cannot be aligned in the front-to-back direction, which makes it difficult to assemble the reinforcing member 50 with the crossbar 20 and the rear frame 13.

[0060] Based on this, in some embodiments, such as Figure 10 As shown, an adjusting member 60 is provided between the reinforcing member 50 and the crossbar 20. The adjusting member 60 is threadedly connected to the reinforcing member 50, and the adjusting member 60 has an oblong hole 61. The oblong hole 61 allows the adjusting member 60 to be adjusted along the length of the crossbar 20 so that the reinforcing member 50 is perpendicular to the crossbar 20, which facilitates the assembly of the reinforcing member 50 with the crossbar 20 and the rear frame 13. Alternatively,

[0061] In some embodiments, an adjusting member 60 is provided between the reinforcing member 50 and the rear frame 13. The adjusting member 60 is threadedly connected to the rear frame 13, and the adjusting member 60 is provided with a waist-shaped hole 61. The waist-shaped hole 61 allows the adjusting member 60 to be adjusted along the length direction of the rear frame 13 so that the reinforcing member 50 is perpendicular to the crossbar 20, which helps to assemble the reinforcing member 50 with the crossbar 20 and the rear frame 13.
