[0002] The button sewing machine generally includes an upper conveying mechanism for conveying upper buttons and a lower conveying mechanism for conveying lower buttons. The upper buttons and lower buttons are respectively conveyed to the upper and lower sides of the clothing fabric, and then the punch rod is punched to form buttons to fit on the clothing fabric. At present, the existing button sewing machine, such as the Chinese patent disclosed in application number 202322601980.8, includes a frame, an upper button feeding vibration plate, a lower button feeding vibration plate, an upper button feeding structure, a driver, an elastic member, a lower button feeding channel, a push rod and a pressing rod hinged on the lower seat, and the frame It is equipped with an upper punch and a lower seat. The upper buckle feeding structure transports the upper buckle in the upper buckle feeding vibration plate to the upper punch. The outer end of the pushing rod is provided with a pushing trough. The lower buckle feeding channel transports the lower buckle in the lower buckle feeding vibration plate to the pushing trough. The elastic part causes the pressing rod to rotate around the hinge point to position the lower buckle in the pushing trough. The lower seat is provided with a positioning hole for positioning the lower buckle. After the driver drives the pushing rod to punch open the pressing rod, the lower buckle in the pushing trough is pushed into the positioning hole. When the driver drives the pushing rod to move, the pushing rod blocks the discharge port of the lower buckle feeding channel.

[0003] However, the above solution has some defects in actual use: after punching a button, the clothing fabric needs to be removed, otherwise the fabric placed on the lower punch will block the feeding of the lower feeding mechanism, making it impossible for the lower button to enter the lower punch, affecting subsequent button sewing. Therefore, the operation is cumbersome, and the operator needs to sew a button once and then put the clothing fabric back before sewing the next button. The labor intensity is high when working for a long time, and the work efficiency is low. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a continuous button sewing auxiliary device for a button sewing machine, which has the advantages of simple and reliable structure, and is convenient for operators to perform continuous button sewing, reduces labor intensity and improves work efficiency.

[0012] In summary, the present invention has the following beneficial effects:

[0013] Compared with the prior art, the present invention provides a liftable auxiliary table, on which the garment fabric is placed. The auxiliary table can be raised and lifted, thereby leaving a discharge space between the mold base and the auxiliary table. At this time, the garment fabric is blocked by the auxiliary table, and the lower conveying mechanism on the button sewing machine can enter the discharge space and send the lower button into the mold base. The upper button is normally sent to the punch rod through the upper conveying mechanism. At this time, the upper and lower buttons are respectively above and below the garment fabric. The table plate of the auxiliary table is also provided with a through hole. During punching, the upper and lower buttons are pressed together and just snapped onto the garment fabric through the through hole. Subsequently, the punch rod rises, the auxiliary table rises and resets, leaving a discharge space for the lower conveying mechanism to send the lower button to the bottom of the garment fabric. In this way, during the button sewing process, the garment fabric can be placed on the auxiliary table at all times, and only needs to be dragged to adjust the position. There is no need to re-pick it up and put it back, which reduces the labor intensity of the operator and improves the work efficiency of the corresponding manual button sewing operation.

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] This embodiment discloses a continuous button-stitching auxiliary device for a button-stitching machine. Figure 1-5 As shown, it includes an auxiliary table 1 arranged on a button sewing machine frame 7, the auxiliary table 1 being arranged between a die base 8 and a punch 9 of the button sewing machine in a liftable manner, a material discharge space 2 being provided between the auxiliary table 1 and the die base, and the material discharge space 2 being provided for a lower conveying mechanism 11 of the button sewing machine to extend into. Through the above structure, the clothing fabric is placed on the auxiliary table 1, and when sewing buttons, the punch 9 and the die base 8 are pressed up and down to press the buttons onto the clothing fabric. After the button sewing is completed, the auxiliary table 1 can be raised to form a material discharge space 2 between it and the die base 8, so that the lower conveying mechanism 11 can convey the lower button into the die base 8 through the material discharge space 2. Since the clothing fabric is on the auxiliary table 1, it will not hinder the conveying of the lower conveying mechanism 11. When sewing buttons continuously, the person can directly drag the clothing fabric on the auxiliary table to adjust the position, without having to re-take it after sewing each button. The labor intensity is reduced and the corresponding work efficiency is also improved.

[0022] Furthermore, the auxiliary table 1 includes a platen 101 and a reset mechanism 102. The reset mechanism 102 is used to drive the platen 101 upward and reset to form a material discharge space 2. The platen 101 is provided with a through hole 3 for button sewing. Through this structure, the reset mechanism 102 can drive the platen 101 to reset, thereby completing the button sewing. After the punch rises, the platen 101 automatically resets, which is more convenient.

[0023] Furthermore, the reset mechanism 102 includes a support rod 1021 that slides on the button sewing machine frame 7 and a reset spring 1022 mounted on the support rod 1021. One end of the reset spring 1022 abuts against the platen 101, and the other end abuts against the button sewing machine frame 7. The support rod 1021 can slide on the frame, thereby limiting the up and down movement of the platen 101. The reset spring 1022 is mounted on the support rod 1021, and the spring's elasticity enables rapid reset. As a result, when the punch 9 presses downward, the platen 101 descends and abuts against the die holder 8, compressing the reset spring 1022. When the punch 9 returns upward, the reset spring 1022 releases its elasticity, causing the platen 101 to rise and reset, re-forming the discharge space 2.

[0024] Furthermore, the diameter of the through hole 3 is smaller than the diameter of the punch rod of the button sewing machine. With the above arrangement, when the punch 9 is pressed downward, it will hit the side of the through hole 3, so that it can move downward together with the platen 101. At the same time, this has the advantage that the punch 9 presses the clothing fabric around the through hole 3. In this way, when sewing the button, the clothing fabric located within the range of the through hole 3 is pressed and positioned. Even if the platen 101 moves, the position of the clothing fabric will not shift, thereby ensuring the accuracy of the button sewing position.

[0025] Furthermore, a mounting hole 4 is provided through the frame of the button sewing machine, through which a support rod 1021 is slidably disposed. A limit member 5 is provided at one end of the support rod 1021 extending through the mounting hole. The limit member 5 is adjustable in the axial direction of the support rod 1021. With the above structure, when the return spring 1022 drives the platen 101 to return, the limit member 5 is used to constrain the movement of the support rod 1021, thereby preventing the platen 101 from rising excessively.

[0026] Furthermore, the support rod 1021 is provided with an external thread, and the limiting component 5 is a nut, which is threadedly engaged with the support rod 1021. Through the threaded engagement of the nut, the limiting component 5 is more convenient to adjust, and the position of the limiting component in the axial direction can be flexibly adjusted by rotation. When dealing with buckles of different sizes, the limiting component 5 can be adjusted, thereby adjusting the size of the discharge space 2, thereby enhancing versatility.

[0027] Furthermore, a shielding cover 6 is included. The shielding cover 6 is arranged on the path of the lower conveying mechanism moving toward the discharge space 2. The shielding cover 6 has a cavity 601 inside to accommodate the movement of the lower conveying mechanism. Because some clothing fabrics are large, the fabric may need to be pushed inward when sewing buttons. In this case, the shielding cover 6 further ensures that the clothing fabric is placed on the shielding cover 6 without blocking the movement of the lower conveying mechanism 11, allowing the operator to continuously drag the fabric to adjust the buttoning position, ensuring convenient and quick operation.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
