Description

Technical Field

[0001] This utility model relates to the field of sewing equipment technology, and more specifically, to a lining placement device and a placket machine. Background Technology

[0002] In garment making, fabric processing, and other fields involving sewing techniques, the stability and flatness of the fabric have a crucial impact on sewing quality. However, in practice, sewing problems often arise due to the characteristics of the fabric, with issues related to lining fabrics being particularly prominent.

[0003] The lining placket is typically a two-layer fabric structure formed by folding the fabric in half. This structure is prone to bulging under normal conditions. When the fabric bulges, its height may exceed the normal operating range of the sewing machine presser foot, causing the presser foot to collide with the fabric. Furthermore, bulging fabric is difficult to sew with stable stitches, leading to uneven stitches, skipped stitches, and other problems, severely affecting the appearance and durability of the finished product. In addition, the lining fabric is also prone to shifting during movement. This shifting results in inaccurate sewing positions, which in turn affects the dimensional accuracy and overall shape of the garment.

[0004] Therefore, how to solve the problem of the lining fabric easily bulging and shifting during the sewing process is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a lining placement device that prevents the lining fabric from bulging or shifting during sewing, thus maintaining a stable stitch and improving the efficiency and accuracy of the sewing process.

[0006] Another objective of this invention is to provide a placket machine that includes the aforementioned inner placket placement device, which can improve sewing precision and quality, enhance production efficiency, and reduce labor intensity.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A lining placement device, comprising:

[0009] Support base;

[0010] Drive component, connected to support base, used to drive the support base to move;

[0011] The lower plate is fixed to the bottom surface of the support base;

[0012] The upper plate has one end rotatably connected to the top surface of the support base, so that the other end of the upper plate can rotate towards and away from the lower plate. There is a space between the upper plate and the lower plate for placing the lining fabric.

[0013] Preferably, the upper plate and the lower plate are provided with sewing avoidance positions, and the sewing avoidance positions of the two overlap, and the sewing avoidance positions are U-shaped elongated holes.

[0014] Preferably, the surfaces of the upper and lower plates are provided with anti-slip textures.

[0015] Preferably, the upper plate is hinged to the support base by at least two hinges.

[0016] Preferably, the support base has an L-shaped structure, and the corner of the support base is provided with a protrusion protruding from the outer edge, and the top surface of the protrusion is a slope.

[0017] Preferably, the support base is connected to the drive component via a connecting component.

[0018] Preferably, the connecting component includes a connecting block and a fisheye connector, and the output end of the drive component is connected to the connecting block through the fisheye connector. The connecting block slides along the guide rail on the mounting plate.

[0019] Preferably, the drive assembly includes a cylinder, the fixed end of which is mounted on the mounting plate via a mounting base, and the output end of which is connected to the connecting block via a fisheye connector.

[0020] Preferably, the extension and retraction of the cylinder is controlled by a control device.

[0021] A placket machine includes the aforementioned inner placket placement device.

[0022] The lining fabric placement device provided by this utility model includes a support base, a drive assembly, a lower plate, and an upper plate. Specifically, the drive assembly is connected to the support base and is used to drive the support base to move. The drive assembly enables the support base to move automatically, making the placement and adjustment of the lining fabric more precise and faster, thereby improving the smoothness and speed of the entire sewing process, increasing production efficiency, and reducing the labor intensity of manual operation. The lower plate is fixed to the bottom surface of the support base, and one end of the upper plate is rotatably connected to the top surface of the support base, so that the other end of the upper plate can rotate towards and away from the lower plate. This facilitates the operator to quickly place and adjust the lining fabric, simplifies the operation process, and also allows the upper plate to rotate as needed, thereby better adapting to lining fabrics of different thicknesses. This adjustable structural design ensures that the fabric will not shift during the sewing process, thus guaranteeing the accuracy of the sewing position.

[0023] There is a space between the upper and lower plates for placing the lining fabric. The lining fabric is fixed by the upper and lower layers to prevent it from bulging during sewing due to the two-layer fabric structure formed by folding. This effectively controls the height of the fabric within the normal working range of the sewing machine presser foot, avoiding collisions between the presser foot and the fabric. This protects both the fabric and the sewing machine presser foot, extending the service life of the equipment. Since the fabric no longer bulges, stable stitches can be maintained during sewing, effectively avoiding problems such as uneven stitches and skipped stitches, significantly improving the appearance quality and durability of the sewn product.

[0024] The lining placement device designed in the above manner can prevent the lining fabric from bulging during sewing, thereby avoiding collision between the presser foot and the fabric, maintaining a stable stitch during sewing, ensuring that the lining fabric does not shift during sewing, and improving the efficiency and accuracy of the sewing process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] It should be noted that the directional terms such as "up" and "down" in the following text are defined based on the accompanying drawings in the instruction manual.

[0042] The core of this invention is to provide a lining fabric placement device that prevents the lining fabric from bulging or shifting during sewing, ensuring stable stitches and improving sewing efficiency and precision. Another core aspect of this invention is to provide a placket machine incorporating the aforementioned lining fabric placement device, which can enhance sewing precision and quality, increase production efficiency, and reduce labor intensity.

[0043] Please refer to Figure 1 and Figure 2 A lining placement device includes a support base 1, a drive assembly 2, a lower plate 3, and an upper plate 4.

[0044] Specifically, the drive component 2 is connected to the support base 1 and is used to drive the support base 1 to move. The drive component 2 enables the support base 1 to move automatically, making the placement and adjustment of the lining fabric more precise and faster, thereby improving the smoothness and speed of the entire sewing process, increasing production efficiency, and reducing the labor intensity of manual operation. The lower plate 3 is fixed to the bottom surface of the support base 1, and one end of the upper plate 4 is rotatably connected to the top surface of the support base 1, so that the other end of the upper plate 4 can rotate towards and away from the lower plate 3, which facilitates the operator to quickly place and adjust the lining fabric, simplifies the operation process, and also allows the upper plate 4 to rotate as needed, thereby better adapting to lining fabrics of different thicknesses. This adjustable structural design ensures that the fabric will not shift during the sewing process, thereby ensuring the accuracy of the sewing position.

[0045] A space for placing the lining fabric is provided between the upper plate 4 and the lower plate 3. The lining fabric is fixed by the upper and lower layers to prevent the fabric from bulging due to the two-layer fabric structure formed by folding during the sewing process. This effectively controls the height of the fabric within the normal working range of the sewing machine presser foot, avoiding collision between the presser foot and the fabric. This protects both the fabric and the sewing machine presser foot, extending the service life of the equipment. Since the fabric no longer bulges, stable stitches can be maintained during the sewing process, effectively avoiding problems such as uneven stitches and skipped stitches, significantly improving the appearance quality and durability of the sewn product.

[0046] The upper plate 4 and the lower plate 3 are arranged vertically and partially overlap.

[0047] The lining placement device designed in the above manner can prevent the lining fabric from bulging during sewing, thereby avoiding collision between the presser foot and the fabric, maintaining a stable stitch during sewing, ensuring that the lining fabric does not shift during sewing, and improving the efficiency and accuracy of the sewing process.

[0048] In the above embodiment, the upper plate 4 and the lower plate 3 are provided with sewing avoidance positions 5, and the sewing avoidance positions 5 of the two overlap, and the sewing avoidance position 5 is a U-shaped elongated hole.

[0049] It should be noted that by setting sewing avoidance points 5 on the upper plate 4 and the lower plate 3, the sewing machine needle can pass smoothly to sew directly onto the fabric. The overlapping sewing avoidance points 5 ensure uniform fabric tension during sewing, avoiding uneven stitches caused by variations in fabric thickness, and improving the quality of the final sewn product. In standard sewing operations, the U-shaped elongated hole design of the upper plate 4 and the lower plate 3 allows the sewing machine needle to smoothly pass from one side of the fabric to the other without pulling or damaging the fabric. This is particularly suitable for situations requiring sewing between two layers of fabric, such as sewing a lining.

[0050] The U-shaped elongated hole is connected to one end edge of the upper plate 4 and the lower plate 3, so as to be set as an opening.

[0051] In the above case, the surfaces of the upper plate 4 and the lower plate 3 are provided with anti-slip texture.

[0052] Understandably, the anti-slip texture increases the friction between the upper plate 4 and lower plate 3 and the lining fabric, helping to hold the fabric in place during sewing and preventing slippage, thus ensuring sewing accuracy. Because the fabric remains stable during sewing, it reduces stitch skew or unevenness caused by fabric movement, improving the final product's sewing quality. Furthermore, the anti-slip design reduces the number of times the fabric needs to be readjusted during sewing, saving time and increasing production efficiency.

[0053] The anti-slip texture can be either dotted, with evenly distributed small raised dots on the surfaces of the upper plate 4 and lower plate 3. These raised dots increase the friction between the fabric and the plate, effectively preventing the fabric from slipping during sewing. Alternatively, it can be striped, with parallel or intersecting striped raised areas on the surfaces of the upper plate 4 and lower plate 3. This striped design provides a continuous friction surface, helping to hold the fabric in place and maintain stability during sewing. A mesh pattern can also be used, with small mesh-like grooves on the surfaces of the upper plate 4 and lower plate 3. This design increases the friction area between the fabric and the plate while reducing direct contact and preventing damage to the fabric. Finally, a wavy pattern can be used, with wavy raised textures on the surfaces of the upper plate 4 and lower plate 3. This wavy design provides additional friction without increasing fabric pressure, helping to hold the fabric in place. The anti-slip texture can also be replaced with a replaceable anti-slip pad. Replaceable anti-slip pads with specific anti-slip textures can be installed on the surfaces of the upper plate 4 and the lower plate 3. This design allows for quick replacement of the appropriate anti-slip pad according to different sewing tasks, increasing the flexibility and adaptability of the equipment.

[0054] Furthermore, the upper plate 4 is hinged to the support base 1 via at least two hinges 6.

[0055] It should be noted that using at least two hinges 6 provides more stable support and connection, ensuring the stability of the upper plate 4 during rotation and preventing inaccurate fabric placement due to unstable connections. The hinge 6 connection allows for some clearance adjustment between the upper plate 4 and the support base 1, accommodating fabrics of different thicknesses and increasing the versatility of the device. As a rotating component, the hinge 6 ensures smooth rotation of the upper plate 4, reducing friction and wear, thereby extending the equipment's lifespan and improving production efficiency. The hinge 6 connection ensures the precision of the upper plate 4's rotation, helping to maintain consistent fabric position during sewing and improving product quality. As an independent component, the hinge 6 can be maintained or replaced individually, simplifying the maintenance process and reducing maintenance costs.

[0056] In one feasible implementation, the upper plate 4 is symmetrically connected to the support base 1 via two hinges 6, each hinge 6 bearing half the weight of the upper plate 4. This design provides balanced support, ensuring the stability and uniformity of the upper plate 4 during rotation, and is suitable for standard-weight upper plates 4 requiring frequent rotation within a moderate range. In another embodiment, the two hinges 6 are located at one end of the upper plate 4 and are arranged side by side.

[0057] In the above embodiment, the support base 1 has an L-shaped structure, and the corner of the support base 1 is provided with a protrusion 7 protruding from the outer edge, and the top surface of the protrusion 7 is a slope.

[0058] Understandably, the beveled design of protrusion 7 allows support 1 to precisely engage with the zipper placement module, ensuring the stability and accuracy of the zipper placement plate when lifted, thereby improving sewing precision. The beveled surface of protrusion 7, in conjunction with the beveled surface on the zipper placement plate, allows for quick lifting of the zipper placement plate, simplifying the operation process, reducing operation time, and improving production efficiency. The L-shaped support 1 provides a robust support base.

[0059] Based on the above embodiment, the support base 1 is connected to the drive component 2 via the connecting component 8. The connecting component 8 includes a connecting block 81 and a fisheye connector 82. The output end of the drive component 2 is connected to the connecting block 81 via the fisheye connector 82, and the connecting block 81 slides along the guide rail 10 on the mounting plate 9.

[0060] It should be noted that the design of the connecting block 81 and the fisheye connector 82 allows for quick assembly and disassembly between the support base 1 and the drive assembly 2, facilitating maintenance and replacement and improving assembly flexibility. The fisheye connector 82 provides a reliable and precise connection, ensuring alignment between the output end of the drive assembly 2 and the connecting block 81, thereby guaranteeing the accuracy of the movement of the support base 1. The design of the connecting block 81 sliding along the guide rail 10 provides accurate guidance for the movement of the upper plate 4 and the lower plate 3, ensuring the smoothness of the connecting block 81 during movement, avoiding jamming and uneven movement, and improving the stability of equipment operation.

[0061] In a preferred embodiment, the drive assembly 2 includes a cylinder, the fixed end of which is mounted on the mounting plate 9 via a fixed seat, and the output end of which is connected to the connecting block 81 via a fisheye connector 82.

[0062] It should be noted that the cylinder's fixed end is connected to the mounting plate 9 via a fixed base, providing a stable support point and ensuring that the cylinder will not move or tilt during operation, thus enhancing the stability of the entire device. The cylinder's fixed end is directly mounted on the mounting plate 9, simplifying the installation process. This design also facilitates cylinder maintenance and replacement. The cylinder's drive method allows for adjustment of pressure and stroke as needed, adapting to different sewing requirements and material properties, enhancing the device's adaptability. The cylinder's rapid response characteristics help increase the device's operating speed, thereby improving production efficiency. Compared to other drive methods (such as electric motors), cylinders typically consume less energy, contributing to reduced overall energy consumption of the device.

[0063] The support base 1 is driven by a cylinder. The piston rod end of the cylinder is connected to a connecting block 81 via a fisheye connector 82. The connecting block 81 is fixed to the support base 1 and slides along the guide rail 10 on the mounting plate 9. The extension and retraction of the cylinder pushes the connecting block 81 to slide along the guide rail 10, thereby moving the support base 1 to the desired position. In automated sewing production lines, the support base 1 needs to be precisely moved to multiple positions to adapt to different sewing tasks.

[0064] In the above situation, the extension and retraction of the cylinder is controlled by a control device.

[0065] Understandably, the control device can precisely control the extension and retraction of the cylinder, ensuring that the support base 1 or other connecting components move to the predetermined position and speed, thereby improving operational accuracy. Automating the cylinder's movement through the control device reduces manual intervention, contributing to the automation of the entire sewing process, improving the automation level of the production line, and making the production process smoother, thus increasing production efficiency and output. The control device can adjust the cylinder's movement according to different production needs, allowing the equipment to flexibly adapt to changing production conditions and process requirements.

[0066] In summary, the lining fabric placement device provided by this utility model, when in use, first flip the upper plate 4 to rotate it away from the lower plate 3 to open the upper plate 4, then place the lining fabric on the lower plate 3, then flip the lower plate 3 to rotate the upper plate 4 towards the lower plate 3 to close the upper plate 4, thereby fixing the lining fabric in the interlayer space between the upper plate 4 and the lower plate 3. Finally, the operating state of the cylinder is controlled by the control device to drive the support plate to move the upper plate 4 and the lower plate 3 synchronously. When it is necessary to sew the lining fabric, the control device controls the extension rod of the cylinder to extend and retract to drive the support seat 1 to move the upper plate 4, the lower plate 3 and the lining fabric to the sewing machine position for sewing.

[0067] This design, through the coordinated work of the upper plate 4 and the lower plate 3, secures the inner fabric, preventing it from bulging during sewing due to the two-layer fabric structure formed by folding. This effectively controls the fabric height within the normal operating range of the sewing machine presser foot, avoiding collisions between the presser foot and the fabric. This protects both the fabric and the presser foot, extending the equipment's lifespan. Since the fabric no longer bulges, stable stitches are maintained during sewing, effectively preventing uneven stitches, skipped stitches, and other problems, significantly improving the appearance quality and durability of the sewn product.

[0068] In addition to the lining placement device disclosed in the above embodiments, this utility model also provides a placket machine including the above-mentioned lining placement device. For the structure of other parts of the placket machine, please refer to the prior art, which will not be repeated here.

[0070] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
