It includes two sidewalls arranged opposite to each other, namely the front sidewall and the rear sidewall, and two sidewalls arranged opposite to each other, namely the left sidewall and the right sidewall; and the front sidewall, the rear sidewall, the left sidewall and the right sidewall together surround an embroidery area. By clamping the fabric on the four sidewalls, the fabric is clamped and fixed, so that the part of the fabric located in the embroidery area can be embroidered to form the required embroidery.

[0003] With the development of industry, the demand for different embroidery techniques is increasing. For example, when using relief embroidery to embroider fabric, it is necessary to first clamp a layer of fabric on the embroidery frame for embroidery, then take the layer of fabric off, put a new layer of fabric on the embroidery frame, and then stack the embroidered fabric on the new layer of fabric, and then clamp the two layers of fabric together and embroider again.

[0004] In this process, the fabric needs to be clamped on the embroidery frame for embroidery first, and then the fabric needs to be taken off the embroidery frame for clamping and embroidery. However, the relative positions of the front and back clamping are difficult to keep consistent. It is common that there is a large deviation between the first clamping position and the second clamping position of the fabric, resulting in the two embroidery operations on the fabric not being well connected, which easily leads to poor embroidery quality.

DETAILED DESCRIPTION

[0042] The present invention is specifically described below with reference to the embodiments:

[0043] Embodiment 1:

[0044] Embroidery frame components, such as Figure 1 To Attachment Figure 3 , including a ring frame a formed by connecting a plurality of side edges a1 end to end and having an embroidery area a2 inside.

[0045] Specifically, the plurality of sidewalls a1 in this embodiment include: Figure 1 The four sidewalls shown in the figure are: front sidewall a101, rear sidewall a102, left sidewall a103 and right sidewall a104. The front sidewall a101 and the rear sidewall a102 are arranged at a relative interval, and the left sidewall a103 and the right sidewall a104 are arranged at a relative interval. Each sidewall is connected end to end to form an annular frame a, and the front sidewall a101, the rear sidewall a102, the left sidewall a103 and the right sidewall a104 are surrounded together to form an embroidery area a2 located inside the annular frame a.

[0046] By clamping and fixing the four sides of the cloth on the four edges using, for example, cloth clamps, that is, clamping and fixing the cloth on the annular frame a, the embroidery needle of the embroidery machine can embroider the cloth corresponding to the embroidery area a2.

[0047] When the annular frame a is used in an embroidery process (such as relief embroidery process) in which the upper layer of fabric needs to be embroidered separately first, and then the upper and lower layers of fabric need to be embroidered at the same time to form an embroidery product with double layers of fabric: the upper layer of fabric needs to be fixed on the annular frame a first time for embroidery, and then the upper layer of fabric needs to be removed as a whole, and the lower layer of fabric needs to be clamped on the annular frame a in sequence, and after the upper layer of fabric has been embroidered in sequence, the second time for embroidery. In this process, since the upper layer of fabric needs to be fixed and clamped first for embroidery, and then removed as a whole and then fixed and clamped for the second time for embroidery, the relative positions of the front and rear clamping are difficult to keep consistent, and the first clamping position and the second clamping position of the fabric often have a large deviation, resulting in the two embroidery operations on the fabric not being well connected and the embroidery quality being easily poor.

[0048] Based on this, as attached Figure 1 As shown, in this embodiment, a horizontal bar a3 is provided in the embroidery area a2, and the horizontal bar a3 in this embodiment is preferably provided close to the rear bar a102, and the rear bar a102 and the horizontal bar a3 are preferably provided at intervals. At this time, the front bar a101, the horizontal bar a3, the left bar a103 and the right bar a104 surround an area for the embroidery needle to run and embroider the fabric.

[0049] And, if attached Figure 1 As shown, the annular frame a is also connected with a lifting component b, and the lifting component b is configured to be connected with the crossbar a3 and to drive the crossbar a3 to enter or leave the embroidery area a2 for lifting.

[0050] When the above-mentioned embroidery frame assembly is used for an embroidery process (such as relief embroidery process) in which the upper layer of fabric needs to be embroidered separately first, and then the upper and lower layers of fabric need to be embroidered simultaneously to form an embroidery product with two layers of fabric:

[0051] The upper layer of fabric and the lower layer of fabric required for the embroidery can be prepared first, and the crossbar a3 is driven to shift to the first position ( Figure 4 At this time, the lower layer of fabric is placed on the annular frame a according to the position state to be fixed, and then the upper layer of fabric is placed on the annular frame a according to the position state to be fixed, and the upper layer of fabric is stacked on the lower layer of fabric, completing the positioning and placement of the double layer of fabric.

[0052] After the positioning and placement is completed, the part of the upper layer of fabric placed on the crosspiece a3 and the part of the lower layer of fabric placed on the crosspiece a3 can be fixed on the crosspiece a3 by the fabric clamp, that is, the positioning and clamping of the double-layer fabric is realized.

[0053] After the positioning and clamping is completed, the lifting component b drives the crossbar a3 to rise and separate from the embroidery area a2 to the second position 9 ( Figure 4 The unclamped portion of the lower fabric can be directly hung down from the embroidery area a2, as long as it does not affect the subsequent fixed embroidery of the upper fabric, or it is preferred to place the unclamped portion of the lower fabric between the back cuff a102 and the cross piece a3 for arrangement.

[0054] After the finishing is completed, the lifting component b can be used again to drive the horizontal bar a3 to move to the first position in the embroidery area a2 to tighten the upper fabric, and the upper fabric can be fixed to the front bar a101, the left bar a103 and the right bar a104 by fabric clamps respectively to fix the upper fabric, so that the first embroidery operation can be performed on the upper fabric.

[0055] After the first embroidery is completed, the cloth clamps on the front rail a101, the left rail a103 and the right rail a104 can be removed first; the lifting component b drives the horizontal rail a3 to rise and disengage from the embroidery area a2 to take out the lower cloth originally placed between the rear rail a102 and the horizontal rail a3; then, the lifting component b drives the horizontal rail a3 to shift to the first position in the embroidery area a2, and then the upper cloth and the lower cloth are fixed to the front rail a101, the left rail a103 and the right rail a104 respectively through the cloth clamps, that is, the upper and lower double layers of cloth are fixed synchronously, and the upper cloth is stacked on the lower cloth. Then, the upper and lower cloths can be embroidered synchronously for the second time.

[0056] In the above process, since a part of the upper fabric is always clamped on the crossbar a3, and no matter it is the first time or the second time embroidery is performed, the crossbar a3 is shifted to the first position in the embroidery area a2; that is, when the upper fabric is clamped twice, the crossbar a3 provides the same positioning and clamping effect on the upper fabric. Therefore, it is only necessary to tighten the upper fabric and fix it on the front section a101, the left section a103 and the right section a104 through the fabric clamps, so that the first clamping position and the second clamping position of the upper fabric can have a high degree of consistency, thereby enabling the two embroidery operations on the upper fabric to be better connected and improving the embroidery quality.

[0057] At the same time, compared with the method of requiring the upper layer of fabric to be disassembled as a whole and then stacked with the lower layer of fabric, in the above process, the part of the fabric clamp that fixes the upper layer of fabric and the lower layer of fabric on the horizontal piece a3 does not need to be disassembled and installed multiple times, and only the fabric clamps on the remaining edges need to be disassembled and clamped according to the process requirements, which reduces the complexity of the fabric clamping action in the overall embroidery process and improves the overall production efficiency.

[0058] Furthermore, the lifting component b can be any device that can achieve the above requirements, such as a robotic arm, etc. In this embodiment, as shown in the attached Figure 1 To Attachment Figure 3 As shown, the lifting assembly b includes a base b01, a push rod device b02 and a lifting arm b03.

[0059] Specifically, as attached Figure 2 and attached Figure 3 As shown, the base b01 is fixed to the rear rail a102 by, for example, screws. The push rod device b02 can be fixed to the rear rail a102, or as shown in the attached Figure 2 As shown in the figure, screws are used to fix the base b01, so that the lifting component b can be installed / disassembled as a whole; the push rod device b02 is a push rod motor or a hydraulic push rod device or a pneumatic push rod device, which has a piston rod b021 that can be telescopically moved; one end of the lifting arm b03 is rotatably connected to the base b01, and the other end is fixed to the cross piece a3 by screws, for example, and the lifting arm b03 is also connected to the piston rod b021, so that the lifting arm b03 can be driven to rotate by the telescopic movement of the piston rod b021, thereby driving the cross piece a3 to rise and fall.

[0060] Furthermore, as attached Figure 2 , Attachment Figure 3 As shown, the piston rod b021 is connected to the lifting arm b03 through the connecting member b04. Figure 2 and attached Figure 3 As shown, the connecting member b04 includes a supporting plate b041 connected to the piston rod b021, and a transition portion connected to the supporting plate b041 and rotatably connected to the lifting arm b03. The supporting plate b041 can be rotatably connected to the piston rod b021. Figure 2 As shown, the vertically telescopic piston rod b021 drives the connecting member b04 to move vertically up and down, thereby driving the lifting arm b03 to rotate relative to the base b01, so as to drive the horizontal bar a3 to move up and down.

[0061] As attached Figure 2 , Attachment Figure 3 As shown, the push rod device b02 in this embodiment is inserted into the installation groove b031 of the lifting arm b03, so that the lifting arm b03 forms a part to surround and protect the push rod device b02, which can protect the push rod device b02 which is easily damaged by collision and reduce the risk of collision damage to the push rod device b02.

[0062] Furthermore, as attached Figure 2 and attached Figure 3As shown, the transfer part includes a first transfer arm b042 located at one side of the piston rod b021 and connected to the top support plate b041, the first transfer arm b042 is rotatably connected to the part of the lifting arm b03 located at one side of the piston rod b021; and a second transfer arm b043 located at the other side of the piston rod b021 and connected to the top support plate b041, the second transfer arm b043 is rotatably connected to the part of the lifting arm b03 located at the other side of the piston rod b021. This enables the push rod device b02 to drive the lifting arm b03 to rotate more stably.

[0063] As attached Figure 2 and attached Figure 3 As shown, the lifting arm b03 extends out of the annular frame a, and the part close to the cross piece a3 is provided with a material storage groove b032 with a notch facing the embroidery area a2, so that when the unclamped part of the lower layer of fabric is placed between the rear section a102 and the cross piece a3, a larger accommodating space can be provided, which is convenient for the temporary accommodation of the fabric.

[0064] Embodiment 2:

[0065] Based on Example 1, as shown in the attached Figure 2 and attached Figure 3 As shown, the cross piece a3 in this embodiment is connected to the lifting arm b03 by using a docking piece a4 fixedly connected to the cross piece a3 by means of screws, for example.

[0066] Among them, in the direction from the cross piece a3 to the push rod device b02, a plurality of docking parts are arranged at intervals on the docking piece a4, and the lifting arm b03 is provided with a fixing part b033 matching the docking part near one end of the docking piece a4; the fixing part b033 can be detachably connected to any docking part to adjust the interval between the cross piece a3 and the rear piece a102, so that the cross piece a3 can be adjusted in position according to the width requirement of the embroidery.

[0067] Specifically, as attached Figure 3 As described, a strip hole a401 is provided on the cross piece a3 in this embodiment, and the strip hole a401 extends in the direction from the cross piece a3 to the push rod device b02, and the fixing portion b033 is a screw provided at the end of the lifting arm b03, and the screw is inserted into the strip hole a401, and the threaded end of the screw passes through the strip hole a401 and is screwed with a nut.

[0068] At this time, any part of the strip hole a401 that can accommodate the screw for insertion is formed with a docking portion.

[0069] By turning the nut to make it press against the docking piece a4, the docking piece a4 and the lifting arm b03 can be detachably fixedly connected. By turning the nut to make it spaced from the docking piece a4, the retaining part b033 of the screw structure can change the insertion position in the strip hole a401, which is equivalent to connecting the retaining part b033 to the docking part at other positions to adjust the fixed position of the crosspiece a3; after the position is adjusted, the nut is turned again to make it press against the docking piece a4, thus achieving the fixed connection between the docking piece a4 and the lifting arm b03.
