[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Currently, sewing cylindrical sleeves requires manual intervention. When sewing cylindrical sleeves, since the sleeve piece is in the shape of a cylinder, after sewing a section of fabric, it is necessary to manually pull the next section of fabric into the sewing area and tidy up the rest of the fabric to ensure the flatness of the sewing area. Otherwise, the sewing part of the fabric and the rest of the fabric will be twisted and become a twisted shape. When the sleeve sewing process is fully automated without manual intervention, this situation will affect the flatness of the fabric in the sewing area on the one hand, and on the other hand, it will cause the fabric to be pulled, resulting in excessive tension beyond expectations, thereby affecting the quality of the sleeve sewing and even causing the sleeve sewing step to fail to proceed smoothly.

[0025] In order to solve the above technical problems, the present application provides a sleeve-stitching cloth support assembly to solve the problem that clothes may twist during the sleeve-stitching process.

[0026] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of the sleeve support cloth assembly provided in an embodiment of the present application, Figure 2 This is a front view of the sleeve cloth support assembly provided in an embodiment of the present application with the cloth support wheel base removed.

[0027] The sleeve cloth-holding assembly mainly includes a driving assembly and a cloth-holding assembly. The driving assembly is a assembly that provides driving force, and the cloth-holding assembly is a assembly that fixes the cloth and drives the cloth to rotate.

[0028] In this embodiment, the driving component is connected to the cloth supporting component, and the cloth supporting component is driven to rotate by the driving component. The cloth supporting component fixes the remaining part of the cloth except for sewing, so that the remaining part of the cloth moves together with the sewing part, thereby eliminating the kink between the remaining part of the cloth and the sewing part.

[0029] The sleeve-stitching cloth support assembly needs to be used in conjunction with the sewing machine part of the automatic sleeve-stitching machine, that is, the sewing machine body. When sewing the sleeves, the sewing part of the fabric is sewn in the sewing machine body, and as the sewing machine body sews and feeds the sewing part of the fabric, the remaining part of the fabric except the sewing part will also move; before this, the excess part of the fabric is put into the sleeve-stitching cloth support assembly, and the sleeve-stitching cloth support assembly drives the fabric to rotate, and then when sewing the sleeves, the remaining part of the fabric in the sleeve-stitching cloth support assembly moves together with the sewing part of the fabric outside the sleeve-stitching cloth support assembly, so that the fabric maintains a relaxed state instead of being twisted like a twist, thereby eliminating the kink between the excess part of the fabric and the sewing part of the fabric, and ensuring the smooth progress of sleeve-stitching.

[0030] It should be noted that the core improvement of this embodiment is that the excess fabric can move with the fabric in the sewing area, so that the two parts of the fabric remain in a relatively stretched state, thereby ensuring the smooth progress of the sleeve sewing process; in addition, there are multiple implementation plans for the drive component and the cloth support component. For example, the cloth support component can adopt a claw-type mechanism, which can clamp the fabric, and the root of the claw-type mechanism can rotate: before sewing the sleeve, the excess garment pieces (the excess part of the fabric) are straightened and the claw-type mechanism is used to clamp the garment pieces. During the sleeve sewing process, as the garment pieces in the sewing area (the sewing part of the fabric) rotate, the claw-type mechanism also clamps the garment pieces and rotates, and the speed is matched to achieve action synchronization within a certain range.

[0031] In a specific embodiment, the cloth supporting assembly includes a cloth supporting wheel 5 and a cloth fixing member.

[0032] In this embodiment, the cloth-supporting wheel 5 is in a circular shape with a hollow interior. The interior of the cloth-supporting wheel 5 is used to support cloth. The cloth-fixing members are arranged along the circumference of the interior of the cloth-supporting wheel 5. The cloth-fixing members are used to fix the supported cloth.

[0033] like Figure 1 and Figure 2 As shown, the circular, hollow cloth-supporting wheel 5 is regarded as a cylinder. When sewing the sleeves, the excess fabric is put into the cylinder, and the fabric fixing part fixes the fabric. The cylinder drives the fabric to rotate so that the excess fabric in the cylinder and the fabric in the sewing area can always remain in a relatively stretched state, which effectively ensures the smooth progress of the sleeve sewing process.

[0034] It should be noted that there are many implementation schemes for the fabric fixing part, including but not limited to adhesive fixing, suction fixing, etc. For example, for adhesive fixing, a sticky tape can be used inside the cloth-supporting wheel 5, and when the cloth-supporting wheel 5 rotates, the tape sticks to the fabric by virtue of its stickiness; for suction fixing, a suction system can be used inside the cloth-supporting wheel 5, and when the cloth-supporting wheel 5 rotates, the suction system sticks to the fabric by virtue of its suction force. Furthermore, the stickiness of the tape in adhesive fixing is designed, and the suction force of the suction system in suction fixing is adjusted, so that the fixing effect of the fabric fixing part on the fabric allows the fabric to be separated from the cloth-supporting wheel 5 when the fabric is driven by the cloth-supporting wheel 5 to the highest point or near the highest point, thereby realizing the flipping of the fabric.

[0035] In a specific embodiment, the cloth fixing piece protrudes toward the inner center of the cloth-supporting wheel 5, and the cloth fixing piece is curved.

[0036] In this embodiment, the protruding and curved cloth fixing part is regarded as a barb. When sewing the sleeve, the cloth supporting wheel 5 rotates in the direction opposite to the bending direction of the cloth fixing part, and the cloth fixing part hooks the cloth.

[0037] like Figure 1As shown, the bending direction of the hook is clockwise, the rotation direction of the cloth-supporting wheel 5 is counterclockwise, and the ends of the hook-type cloth fixing parts are all facing the counterclockwise rotation direction. When sewing sleeves, the cloth-supporting wheel 5 rotates counterclockwise, and the hook-type cloth fixing parts hook the cloth, fix the cloth, and make the cloth and the cloth-supporting wheel 5 rotate together.

[0038] It should be noted that the bending angle of the hook-type fabric fixing piece should not be too large, so as to ensure that the fabric can be smoothly hooked at the lowest point and can be smoothly detached near the highest point.

[0039] In some embodiments, a protruding structure is further arranged on the inner circumference of the cloth wheel 5 .

[0040] In this embodiment, the raised structure is arranged between adjacent cloth fixing parts, and the contact area between the cloth support wheel 5 and the cloth is increased by the raised structure, thereby enhancing the friction between the cloth support wheel 5 and the cloth, thereby improving the cloth support and fixing effect of the cloth support wheel 5.

[0041] In a specific embodiment, the sleeve-stitching cloth-holding assembly further includes a cloth-holding wheel base 1, which serves as a bearing base of the sleeve-stitching cloth-holding assembly. The cloth-holding wheel base 1 is equipped with a driving assembly and a supporting assembly, and the cloth-holding assembly is assembled through the supporting assembly. When in use, the cloth-holding wheel base 1 is fixed to one side of the sewing machine body, and the cloth-holding assembly supports and fixes the inserted cloth, and the driving assembly drives the cloth-holding assembly to rotate, so that the excess part of the cloth in the cloth-holding assembly and the sewing part of the cloth in the sewing machine body move together to eliminate kinks.

[0042] It should be noted that there are many implementation schemes of the driving assembly, that is, there are many ways to drive the cloth-supporting wheel 5 in the cloth-supporting assembly. For example, it can be driven by a synchronous belt or synchronous pulley, it can be driven by a gear or rack, it can be driven by a rotary slide, an additional mechanism (such as a ratchet mechanism or a grooved wheel mechanism) can be designed to drive the cloth-supporting wheel 5 to rotate intermittently or continuously, or other transmission methods such as hydraulic transmission can be used.

[0043] In a specific embodiment, the driving assembly includes a driving member and a support driving wheel 4.

[0044] In this embodiment, the driving member is connected to the cloth supporting driving wheel 4, and the cloth supporting driving wheel 4 is driven to rotate by the driving member. The cloth supporting driving wheel 4 is in tight contact with the outer periphery of the cloth supporting wheel 5 in the cloth supporting assembly, and the friction force between the cloth supporting driving wheel 4 and the cloth supporting wheel 5 is utilized so that the cloth supporting wheel 5 in the cloth supporting assembly is driven to rotate by the cloth supporting driving wheel 4.

[0045] Exemplarily, the driving member is a motor 7, the output end of which is directly connected to the rotating shaft of the cloth-supporting driving wheel 4. The cloth-supporting driving wheel 4 is rotatably assembled on the cloth-supporting wheel base 1. The motor 7 drives the cloth-supporting driving wheel 4 to rotate, and the cloth-supporting driving wheel 4 drives the cloth-supporting wheel 5 to rotate, thereby driving the cloth placed in the cloth-supporting wheel 5 to rotate and flip.

[0046] In some embodiments, the support assembly includes a cloth wheel bracket 2.

[0047] In this embodiment, the cloth support wheel bracket 2 is divided into two groups, front and rear, the cloth support wheel bracket 2 is installed on the cloth support wheel base 1, and the cloth support assembly is assembled between the front and rear groups of cloth support wheel brackets 2. The cloth support assembly is limited in the axial direction through the front and rear groups of cloth support wheel brackets 2, so that the cloth support wheel 5 has no movement in other directions except rotation.

[0048] In some embodiments, the support assembly further includes a cloth support driven wheel 3 and a cloth support tensioning wheel 6.

[0049] In this embodiment, the cloth-supporting driven wheel 3 is mounted on the cloth-supporting wheel base 1, and the cloth-supporting driven wheel 3 and the cloth-supporting wheel base 1 are also in a rotational assembly relationship, and the cloth-supporting driven wheel 3 is in tight contact with the periphery of the cloth-supporting assembly. The cloth-supporting tensioning wheel 6 is mounted on the cloth-supporting wheel bracket 2, and the cloth-supporting tensioning wheel 6 and the cloth-supporting wheel bracket 2 are in a rotational assembly relationship, and the cloth-supporting tensioning wheel 6 is in tight contact with the periphery of the cloth-supporting assembly. The cloth-supporting assembly is limited in the circumferential direction of the cloth-supporting assembly by the cloth-supporting driving wheel 4, the cloth-supporting driven wheel 3 and the cloth-supporting tensioning wheel 6, so that the cloth-supporting wheel 5 has no movement in other directions except rotation.

[0050] Furthermore, a pattern is designed on the outer surface of the cloth-supporting wheel 5 to increase the friction with the wheel body. The cloth-supporting driving wheel 4, the cloth-supporting driven wheel 3 and the cloth-supporting tensioning wheel 6 are distributed in a triangle, with the cloth-supporting tensioning wheel 6 located at the upper corner, and the cloth-supporting driving wheel 4 and the cloth-supporting driven wheel 3 located at the two lower corners, so as to increase the stability of supporting the cloth-supporting wheel 5. When in use, the cloth-supporting wheel 5 is confined in the middle of the cloth-supporting wheel bracket 2, and the cloth-supporting wheel 5 is pressed against the cloth-supporting driving wheel 4 and the cloth-supporting driven wheel 3 by the cloth-supporting tensioning wheel 6; when the motor 7 drives the cloth-supporting driving wheel 4, the cloth-supporting wheel 5 rotates under the action of friction; the cloth-supporting driven wheel 3 and the cloth-supporting tensioning wheel 6 also rotate under the action of friction, playing an auxiliary role.

[0051] In some embodiments, the degree of compression of the cloth support assembly by the cloth support tensioning wheel 6 is adjustable.

[0052] In this embodiment, the mounting hole of the cloth support tensioning wheel 6 on the cloth support wheel bracket 2 is a waist-shaped hole, which is used to adjust the height of the cloth support tensioning wheel 6, thereby adjusting the degree of pressure of the cloth support tensioning wheel 6 against the cloth support wheel 5.

[0053] In a specific embodiment, the sleeve sewing cloth support assembly is used in an automatic sleeve sewing machine. During operation, the entire piece of cloth except the cylindrical sleeve sewing part will be straightened and put into the cloth support wheel 5, and placed on the lower inner wall of the cloth support wheel 5. The cloth support wheel 5 is hollow inside, and the inner wall is evenly distributed with small protrusions and barbs with a uniform direction (towards the counterclockwise rotation direction). During the counterclockwise rotation of the cloth support wheel 5 as shown in the figure, the cloth placed on the lower inner wall of the cloth support wheel 5 will be caught by the barbs and rotate with the barbs. When it rotates to a position close to the highest point, the cloth will detach from the barbs and fall under the action of gravity, and be placed on the lower inner wall of the cloth support wheel 5 again, and the cloth will be flipped over from then on.

[0054] Based on the above principle, the excess fabric of the garment is turned over, and the turning over is basically synchronized with the fabric movement in the sleeve sewing area, which effectively ensures the smooth progress of the sleeve sewing work. The rotation speed of the cloth-supporting wheel 5 does not need to be completely consistent with the sewing speed, but only needs to synchronize the movements of the two within a certain range.

[0055] The present application also provides an automatic sleeve sewing machine, comprising the above-mentioned sleeve sewing cloth support assembly and a sewing machine body, wherein the sleeve sewing cloth support assembly is arranged on one side of the sewing machine body.

[0056] The automatic sleeve sewing machine should have all the beneficial effects of the above-mentioned sleeve sewing cloth support assembly; the sleeve sewing cloth support assembly replaces the action of manually turning the cloth during the machine sleeve sewing process to ensure smooth sleeve sewing. It is conducive to the automation of the sleeve sewing process and reduces labor costs; the sleeve sewing cloth support assembly solves the problem that when the fully automatic sleeve sewing machine is working, the cloth in the sewing area is twisted with the rest of the cloth, resulting in poor sleeve sewing quality or even inability to proceed; there is no similar mechanism on the market at present, filling the market gap.

[0057] It should be noted that many of the components mentioned in this application are universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0058] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
