Description

Technical Field

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

[0002] In garment manufacturing, especially in trouser production, the sewing of the zipper at the placket is a crucial step. The zipper at the placket not only needs to be sewn precisely but also needs to form an aesthetically pleasing seam, which places high demands on the sewing craftsmanship. Traditional hand-sewing methods rely on the operator's experience, which is not only inefficient but also makes it difficult to guarantee sewing accuracy and aesthetics. With the development of automation technology, people have begun to explore automated sewing equipment to improve production efficiency and product quality.

[0003] However, ensuring the stability of the fabric's edge during automated sewing is a technical challenge. The stability of the edge directly affects the sewing effect of the zipper. When the edge retainer plate is pressed down, its front end needs to maintain a distance of approximately 2mm from the front end of the edge forming plate to ensure the fabric edge is stably fixed. However, during the rotation of the edge retainer plate, it often interferes with the limiting plate, preventing smooth pressing. Although this problem can be solved by moving the limiting plate to the right, this operation is cumbersome, increasing the complexity of the equipment and the difficulty of operation.

[0004] Therefore, how to solve the problem of interference between the stop retaining plate and the limit plate during rotation 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 material holding device that can effectively prevent the stop holding plate from interfering with the limiting plate during rotation, thereby improving the reliability of the device and increasing production efficiency.

[0006] Another objective of this invention is to provide a placket processing equipment that includes the above-mentioned pressure holding device, thereby improving production efficiency.

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.

[0038] It should be noted that the directional terms such as "left," "right," "up," and "down" used below are defined based on the accompanying diagrams in the instruction manual.

[0039] The core of this invention is to provide a material holding device that effectively prevents interference between the stop holding plate 4 and the limiting plate 3 during rotation, thereby improving the reliability of the device and increasing production efficiency. Another core aspect of this invention is to provide a placket processing equipment that includes the aforementioned material holding device, further improving production efficiency.

[0040] Please refer to Figure 1 and Figure 2 A material holding device includes a base plate 1, a stop forming plate 2, a limiting plate 3, a stop holding plate 4, and a driving structure 5.

[0041] Specifically, the stop forming plate 2 and the limiting plate 3 are disposed on the base plate 1, with the limiting plate 3 positioned above the stop forming plate 2. The stop forming plate 2 forms the stop of the fabric, and the limiting plate 3 restricts the position of the fabric to prevent displacement during sewing, thereby improving sewing accuracy. The stop retaining plate 4 is rotatably disposed on the base plate 1 and can move towards and away from the limiting plate 3, allowing the operator to more easily control the position of the stop retaining plate 4, effectively preventing interference between the stop retaining plate 4 and the limiting plate 3 during rotation. The drive structure 5 is used to position the stop retaining plate 4 in a preset position after it has been flipped over, to adapt to different sewing needs.

[0042] The pressure holding device set up in the above manner effectively avoids interference between the stop holding plate 4 and the limit plate 3 during rotation, which improves the reliability of the device, simplifies the operation process, and improves production efficiency.

[0043] In the above embodiment, the two ends of the side of the stop retaining plate 4 away from the stop forming plate 2 are hinged to the base plate 1 by hinges 6.

[0044] It should be noted that the hinged design allows the stop retaining plate 4 to rotate freely within a certain range, so that the stop retaining plate 4 can be easily adjusted to a suitable position as needed, facilitating quick and accurate positioning of the fabric stop and improving sewing efficiency. The hinge 6 connection can reduce the direct friction between the stop retaining plate 4 and the base plate 1, thereby reducing wear and extending the service life of the device.

[0045] In practical applications, there are no restrictions on the number or location of the hinges 6, as long as the aforementioned technical effects can be achieved.

[0046] In the above case, the stop retaining plate 4 is provided with a long groove 41, and the stop retaining plate 4 and the hinge 6 are slidably connected through the long groove 41 and the screw 7.

[0047] It is understood that the hinge 6 has a threaded hole for mounting the screw 7. The screw 7 is passed sequentially through the elongated slot 41 on the stop retaining plate 4 and the threaded hole on the hinge 6, and the position of the screw 7 is fixed by a nut to prevent the screw 7 from coming out of the threaded hole during use. A certain gap is left between the head of the screw 7 and the stop retaining plate 4 to allow the stop retaining plate 4 to slide relative to the base plate 1. The elongated slot 41 extends in the direction approaching and away from the stop forming plate 2, that is... Figure 1 and Figure 2 In the left and right direction, when the stop retaining plate 4 slides left and right relative to the base plate 1, the screw 7 slides in the long groove 41.

[0048] The design of the elongated groove 41 allows the stop retainer plate 4 to slide along the groove within a certain range, facilitating adjustment of its position according to sewing requirements and achieving precise fabric positioning. Through the sliding connection between the elongated groove 41 and the screw 7, the distance between the stop retainer plate 4 and the hinge 6 can be flexibly adjusted to accommodate fabrics of different thicknesses or sizes, improving assembly flexibility, simplifying the adjustment process of the stop retainer plate 4, making operation more convenient, and increasing operator efficiency. The rapid adjustment and positioning capability of the stop retainer plate 4 helps shorten the sewing cycle and improve overall production efficiency.

[0049] In one feasible implementation, the drive structure 5 includes a first positioning magnet disposed on the stop retaining plate 4 and a second positioning magnet disposed on the base plate 1. The first positioning magnet and the second positioning magnet interact to place the stop retaining plate 4 in a preset position.

[0050] It should be noted that using the interaction force of magnets for positioning ensures that the stop retainer plate 4 is in the preset position, thereby improving sewing accuracy. The attractive force provided by the magnet helps stabilize the stop retainer plate 4, preventing it from shifting due to fabric movement or machine vibration during sewing. Magnetic positioning simplifies the adjustment process of the stop retainer plate 4, allowing operators to quickly adjust it to the required position and improve work efficiency.

[0051] Magnetic positioning eliminates the need for mechanical contact, reducing wear between mechanical parts and extending equipment lifespan. It also reduces noise levels during operation, improving the working environment. Furthermore, it is relatively simple, easy to maintain and clean, minimizing maintenance time and costs. In practical applications, the number and placement of magnets can be limited.

[0052] Specifically, when the fabric needs to be fixed, the stop retaining plate 4 is in its initial position, at which point it is located on the far left. Rotate the stop retaining plate 4 downwards. When it is rotated to a position below the limiting plate 3, the stop retaining plate 4 can be moved to the right. At this time, the screw 7 slides in the long groove 41, and the stop retaining plate 4 moves to the right relative to the base plate 1. When it is pressed down into place, the magnet on the stop retaining plate 4 interacts with the magnet on the base plate 1 to make the stop retaining plate 4 reach the preset position to fix the fabric. When the fabric needs to be removed, rotate the stop retaining plate 4 upwards. When it is rotated to a position below the limiting plate 3, the stop retaining plate 4 can be moved to the left to avoid the limiting plate 3. At this time, the screw 7 slides in the long groove 41, and the stop retaining plate 4 moves to the left relative to the base plate 1. After flipping into place, the fabric can be removed.

[0053] In another feasible embodiment, the drive structure 5 includes an elastic element disposed between the hinge 6 and the stop retaining plate 4, the elastic element being used to provide a preload force to move the stop retaining plate 4 toward the stop forming plate 2.

[0054] Understandably, the positioning of the retaining plate 4 is no longer achieved through magnets, but rather through an elastic element positioned between the hinge 6 and the retaining plate 4. The preload provided by the elastic element helps the retaining plate 4 to contact the fabric more tightly, thereby enhancing the fabric's stability during sewing. By ensuring a constant contact pressure between the retaining plate 4 and the fabric, the elastic element helps improve the precision of the sewing process, ensuring even and neat stitches.

[0055] Specifically, when it is necessary to fix the fabric, the stop retaining plate 4 is in its initial position, at which point it is located on the far right. Rotating the stop retaining plate 4 downwards, when it is positioned above the limiting plate 3, a force can be applied to the left. At this point, the screw 7 slides within the long groove 41, causing the stop retaining plate 4 to move to the left relative to the base plate 1 to avoid the limiting plate 3. Continuing to rotate the stop retaining plate 4 downwards, when it is positioned below the limiting plate 3, the applied force is released. Under the preload of the elastic element, the stop retaining plate 4 moves to the right, so that it is in the preset position. Position the fabric to secure it in place and prevent it from wobbling during the securing process. When it is necessary to remove the fabric, rotate the stop retaining plate 4 upwards. When it is rotated to a position below the limiting plate 3, apply a force to the left. At this time, the screw 7 slides in the long groove 41, causing the stop retaining plate 4 to move to the left relative to the bottom plate 1 to avoid the limiting plate 3. Continue to rotate the stop retaining plate 4 upwards. When it is rotated to a position above the limiting plate 3, release the applied force. The stop retaining plate 4 moves to the right under the preload of the elastic element to return the stop retaining plate 4 to its initial position, and the fabric can then be removed.

[0056] In another feasible embodiment, the drive structure 5 includes a limiting block, which is disposed on the base plate 1 and located between the two hinges 6. The limiting block has an irregularly shaped inclined surface that contacts the stop retaining plate 4, so that the stop retaining plate 4 avoids the limiting plate 3 during the flipping process.

[0057] It should be noted that the irregularly shaped bevel design allows the stop retaining plate 4 to smoothly avoid the limiting plate 3 during flipping, preventing direct interference between mechanical parts, reducing mechanical wear and the risk of failure, and maintaining precise fabric positioning, thereby improving sewing accuracy and consistency. The limiting block allows the stop retaining plate 4 more freedom of movement during flipping, improving the operational flexibility of the device and enabling it to adapt to different sewing needs. Specifically, the limiting blocks with irregularly shaped bevels of different specifications can be designed according to the actual path to avoid the limiting plate 3.

[0058] Specifically, when the fabric needs to be secured, the stop retaining plate 4 is in its initial position, at which point it is located on the far left. Rotating the stop retaining plate 4 downwards causes it to contact the irregularly shaped inclined surface. Before rotating it below the limiting plate 3, it is located to the left of the limiting plate 3 and will not interfere with it. After rotating it below the limiting plate 3, the stop retaining plate 4 gradually moves to the right under the push of the irregularly shaped inclined surface until it is pressed down into place, at which point it is in the preset position to secure the fabric. When the fabric needs to be removed, rotating the stop retaining plate 4 upwards causes it to rotate along the irregularly shaped inclined surface, gradually moving it to the left without interfering with the limiting plate 3. Continuing to rotate the stop retaining plate 4 upwards back to its initial position allows the fabric to be removed.

[0059] The irregular inclined surface of the limit block can be designed according to the actual application, and there are no restrictions on it.

[0060] In another feasible embodiment, the stop retaining plate 4 includes two slidably connected left and right plates. In this case, the stop retaining plate 4 does not need to be provided with the elongated groove 41, and can slide left and right to avoid the limiting plate 3.

[0061] Understandably, the sliding connection allows the stop retaining plate 4 to extend and retract within a certain range, thereby avoiding the limiting plate 3 during rotation, increasing the operational flexibility of the device, enabling the stop retaining plate 4 to adapt to fabrics of different widths, and improving the device's adaptability to fabrics of different sizes.

[0062] In a preferred embodiment, the left plate and the right plate are connected by an elastic element, which provides a preload force to move the right plate toward the stop forming plate 2.

[0063] It should be noted that a slide groove can be provided in the left plate body, and the right end of the left plate body is fitted onto the left end of the right plate body, so that the right plate body slides in the slide groove. The elastic element is provided in the slide groove, and one end of the elastic element is connected to the left plate body and the other end is connected to the right plate body. The elastic element provides a preload force to move the right plate body toward the stop forming plate 2.

[0064] Specifically, when it is necessary to fix the fabric, the stop retaining plate 4 is in its initial position, at which time the stop retaining plate 4 is located on the far right. Rotate the stop retaining plate 4 downwards. When it is rotated above the limiting plate 3, a force can be applied to the left. At this time, the right plate body slides to the left in the groove, so that the right plate body avoids the limiting plate 3. Continue to rotate the stop retaining plate 4 downwards. When it is rotated below the limiting plate 3, release the applied force. The right plate body moves to the right under the preload of the elastic element, so that the stop retaining plate 4 is in the preset position. The right plate is positioned to secure the fabric and prevent it from wobbling during the securing process. When the fabric needs to be removed, rotate the stop retaining plate 4 upwards. When it is rotated to a position below the limit plate 3, apply a force to the left. At this time, the right plate slides to the left in the groove to avoid the limit plate 3. Continue to rotate the stop retaining plate 4 upwards. When it is rotated to a position above the limit plate 3, release the applied force. The right plate moves to the right under the pre-tightening force of the elastic element so that the stop retaining plate 4 returns to its initial position, and the fabric can be removed.

[0065] In the above case, the elastic element is a spring.

[0066] Understandably, compared to pneumatic or hydraulic systems, springs do not require an external energy source to maintain preload, thus potentially reducing the energy consumption of the entire sewing system. Springs typically have high fatigue strength, enabling them to withstand prolonged cyclic loading and improving the overall durability of the device. Springs are also a cost-effective standard component that is easy to assemble.

[0067] In summary, the material holding device provided by this utility model effectively avoids interference between the stop holding plate 4 and the limiting plate 3 during rotation by precisely controlling the position of the stop holding plate 4, thereby ensuring the stability of the fabric during sewing and improving sewing accuracy.
