Abstract
Description
Technical Field
[0001] This utility model relates to the field of sewing equipment technology, and more specifically, to a zipper placement plate rotating connection structure and a placket machine. Background Technology
[0002] In existing zipper fixing devices, the connection method between the zipper placement plate and the rotating and fixed seats has certain limitations. Specifically, the rotating seat and fixed seat of the zipper placement plate are usually connected by a rotatable connection. Although this connection method can realize the basic rotation function of the zipper placement plate, in actual use, a certain machining gap inevitably exists between the rotating seat and the fixed seat. This gap is generated during the manufacturing process.
[0003] Because zipper trays typically have long cantilever arms, this structural feature amplifies the impact of machining clearances during rotation. Specifically, the leverage effect of the cantilever arms causes what would otherwise be a small machining clearance to shift significantly at the end of the cantilever. This amplification effect makes the zipper tray prone to displacement during rotation. This displacement not only affects the accuracy of the zipper's position but can also lead to misalignment during sewing, reducing sewing precision and potentially impacting the quality of the final product and the user experience.
[0004] Therefore, how to solve the problem of the zipper placement plate easily shifting when rotating 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 rotating connection structure for a zipper placement plate, which can compensate for gap changes caused by processing or wear, and ensure that the zipper placement plate will not shift during movement, thereby ensuring the stability and accuracy of the zipper placement plate during the sewing process.
[0006] Another objective of this invention is to provide a placket sewing machine that includes the above-mentioned rotating connection structure for the zipper placement plate, which can ensure stability and accuracy during the sewing process.

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.

[0037] The core of this invention is to provide a rotating connection structure for the zipper placement plate, which can compensate for gap changes caused by processing or wear, ensuring that the zipper placement plate 5 will not shift during movement, thereby guaranteeing the stability and accuracy of the zipper placement plate 5 during the sewing process. Another core aspect of this invention is to provide a placket sewing machine including the aforementioned rotating connection structure for the zipper placement plate, which can guarantee the stability and accuracy during the sewing process.
[0038] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A rotating connection structure for a zipper placement plate includes a fixed base 1, a U-shaped rotating base 2, and an adjustment drive mechanism 6.
[0039] Specifically, the U-shaped rotary seat 2 has a mounting groove for mounting the fixed seat 1, providing a clear mounting position for the fixed seat 1. This allows the fixed seat 1 to be accurately installed on the U-shaped rotary seat 2, improving assembly accuracy and efficiency, simplifying the assembly process, and reducing assembly difficulty. A limiting block 3 is provided between the U-shaped rotary seat 2 and the fixed seat 1, which helps to reduce or eliminate the machining gap between the U-shaped rotary seat 2 and the fixed seat 1, thereby reducing the displacement of the zipper placement plate 5 during rotation and improving the stability and accuracy of the structure. The limiting block 3 is rotatably connected to the fixed seat 1 and the U-shaped rotary seat 2 via a pin 4, and the position of the limiting block 3 can be flexibly adjusted to adapt to different working conditions. The U-shaped rotating seat 2 is connected to one end of the zipper placement plate 5, ensuring that the zipper placement plate 5 and the U-shaped rotating seat 2 rotate synchronously, improving the accuracy of zipper placement and the efficiency of sewing operations. The adjusting drive mechanism 6 is located on the fixed seat 1. The adjusting drive mechanism 6 abuts against the limiting block 3 and is used to drive the limiting block 3 to move along the axis parallel to the pin 4. The adjusting drive mechanism 6 acts directly on the limiting block 3, and the limiting block 3 precisely controls the gap between the U-shaped rotating seat 2 and the fixed seat 1 to compensate for gap changes caused by processing or wear, ensuring that the zipper placement plate 5 will not shift during movement, thereby ensuring the stability and accuracy of the zipper placement plate 5 during the sewing process.
[0040] The limiting block 3 is a retaining ring, and the pin 4 passes through the fixed seat 1, the retaining ring, and the U-shaped rotating seat 2, ensuring precise alignment and fixation between the components, thereby improving assembly accuracy. The U-shaped rotating seat 2 rotates around the pin 4, facilitating the rotation operation of the zipper placement plate 5 to adapt to different sewing needs. The zipper placement plate 5 is fixed on the U-shaped rotating seat 2, and the zipper reinforcing plate is fixed on the zipper placement plate 5 to enhance its strength and ensure its stability and durability during sewing. Magnets are fixed to the zipper reinforcing plate, the zipper placement plate 5, and the zipper pressure plate, using magnetic force to enhance the fixing effect of the zipper placement plate 5 and prevent displacement during sewing.
[0041] The rotating connection structure of the zipper placement plate, as described above, can effectively solve the common problem of gaps in the rotating position of rotating long cantilever parts. By adjusting the combination of the drive mechanism 6 and the limit block 3, the gap between the U-shaped rotating seat 2 and the fixed seat 1 is precisely controlled, ensuring a tight fit between the parts, compensating for gap changes caused by processing or wear, and ensuring that the zipper placement plate 5 will not shift during its movement, thereby ensuring the stability and accuracy of the zipper placement plate 5 during the sewing process.
[0042] Please refer to Figure 2The adjustment drive mechanism 6 includes an adjustment screw 61, which passes through one side plate of the U-shaped rotating seat 2. The end of the adjustment screw 61 abuts against the limiting block 3. The gap between the fixed seat 1 and the U-shaped rotating seat 2 is adjusted by rotating the adjustment screw 61.
[0043] It should be noted that the design of the adjusting screw 61 allows the operator to precisely adjust the gap between the fixed seat 1 and the U-shaped rotating seat 2, ensuring that the zipper placement plate 5 maintains ideal stability and accuracy under various working conditions. The adjustment screw 61 is easy to operate, requiring no complex tools or techniques, allowing the operator to quickly adjust the structure to adapt to different sewing tasks, thus improving work efficiency. Precise gap adjustment reduces the risk of displacement of the zipper placement plate 5 due to excessive gap, thereby improving structural stability and ensuring accuracy during the sewing process.
[0044] In the above case, the adjustment drive mechanism 6 also includes a first locking nut 62 provided on the adjusting screw 61, the first locking nut 62 being used to lock the position of the adjusting screw 61.
[0045] Understandably, the design of the first locking nut 62 ensures the stability of the position of the adjusting screw 61. Once the adjusting screw 61 is adjusted to the appropriate gap, the locking nut can fix the position, which can reduce gap changes caused by vibration or accidental collisions during operation, thereby reducing component wear and extending the service life of the equipment.
[0046] Adjusting screw 61 is installed on the U-shaped rotating seat 2. Adjusting screw 61 is used to adjust the gap between the limiting block 3, the U-shaped rotating seat 2, and the fixed seat 1. Through fine adjustment, it ensures that the U-shaped rotating seat 2 rotates smoothly while keeping the gap within a minimum range. This design not only improves the structural tightness but also enhances the retaining ring's ability to withstand larger axial forces. During the movement of the zipper placement plate 5, even under external force, its positional stability is ensured, preventing displacement and thus guaranteeing the accuracy and reliability of the sewing operation. The first locking nut 62 is used to lock the adjusting screw 61, ensuring that the adjusted gap setting will not easily change, providing long-term stable performance.
[0047] Please refer to Figure 3 The U-shaped rotating seat 2 has a first inner sidewall and a second inner sidewall that are arranged opposite to each other. The first inner sidewall is provided with a limiting protrusion 21 that protrudes toward the second inner sidewall. A limiting space is formed between the limiting protrusion 21 and the second inner sidewall for initially limiting the fixed seat 1.
[0048] It should be noted that the limiting space formed between the limiting protrusion 21 and the second inner sidewall provides a preliminary constraint on the fixed seat 1, enhancing its stability within the U-shaped rotating seat 2 and preventing unnecessary movement during sewing. By initially restricting the fixed seat 1 with the limiting protrusion 21, the relative movement between the fixed seat 1 and the U-shaped rotating seat 2 due to processing clearances can be reduced, thereby improving the overall performance of the structure. The limiting protrusion 21 provides a clear assembly position for the fixed seat 1, simplifying the assembly process and making assembly work faster and more accurate.
[0049] In the above embodiment, the U-shaped rotating seat 2 is provided with a limiting component 7 for limiting the rotation of the U-shaped rotating seat 2 to the correct position.
[0050] Understandably, the limiting component 7 ensures that the U-shaped rotating seat 2 stops accurately when it reaches the predetermined position, thereby guaranteeing the precise positioning of the zipper placement plate 5, improving the operational reliability of the entire zipper fixing device, and reducing sewing errors caused by inaccurate positioning. The limiting component 7 helps to provide additional stability when the U-shaped rotating seat 2 reaches the working position, preventing it from shifting or shaking during sewing.
[0051] Based on the above embodiments, the limiting components 7 are provided in two sets, and the two sets of limiting components 7 are symmetrically arranged on both sides of the U-shaped rotating seat 2.
[0052] It should be noted that the two sets of symmetrical limiting components 7 provide more balanced stability, ensuring that the U-shaped rotating seat 2 is evenly stressed in any position, thereby improving the overall structural stability. The symmetrically arranged limiting components 7 help enhance the rigidity of the U-shaped rotating seat 2, reducing potential deformation or bending during sewing and ensuring accurate positioning of the zipper placement plate 5. By distributing the limiting action, the two sets of limiting components 7 can reduce single-point wear and extend the service life of the U-shaped rotating seat 2 and the limiting components 7.
[0053] Please refer to Figure 2 and Figure 4 The limiting component 7 includes a ball screw 71, which is mounted on the U-shaped rotating seat 2. The ball of the ball screw 71 protrudes from the inner side wall of the U-shaped rotating seat 2. The fixing seat 1 is provided with a limiting groove 11 for limiting the ball.
[0054] Understandably, the ball bearing of the ball screw 71 engages with the limiting groove 11 on the fixed base 1 to precisely control the rotational position of the U-shaped rotating base 2, ensuring accurate positioning of the zipper placement plate 5 during sewing. The design of the ball screw 71 allows for flexible adjustment of the position of the U-shaped rotating base 2 within a certain range, enhancing the adaptability and flexibility of the structure. The engagement of the ball bearing with the limiting groove 11 reduces direct contact between the U-shaped rotating base 2 and the fixed base 1, thereby reducing wear and improving the overall durability of the structure.
[0055] In a preferred embodiment, the limiting component 7 further includes a second locking nut 72 disposed on the ball screw 71, the second locking nut 72 being used to lock the position of the ball screw 71.
[0056] It should be noted that the second locking nut 72 can firmly lock the position of the ball screw 71, ensuring that the limiting component 7 will not be displaced due to vibration or external force during sewing, thus guaranteeing the stability of the limiting. With the second locking nut 72, the operator can quickly and easily adjust and fix the position of the ball screw 71, simplifying the operation process and improving work efficiency.
[0057] In one feasible implementation, the limiting component 7 includes a protrusion and a groove. The protrusion is disposed on the first inner sidewall and the second inner sidewall of the U-shaped rotating seat 2, and the groove is disposed on the side of the fixed seat 1 opposite to the first inner sidewall and the second inner sidewall, so that after the U-shaped rotating seat 2 rotates, the protrusion can be locked in the groove to achieve effective limiting of the U-shaped rotating seat 2.
[0058] In practical applications, the limit component 7 can also adopt other limit methods, and there are no restrictions on this.
[0059] In summary, the zipper placement plate rotating connection structure provided by this utility model uses adjusting screw 61 to finely adjust the retaining ring, ensuring that the gap between the fixed seat 1 and the U-shaped rotating seat 2 can approach zero, thereby achieving highly accurate positioning. The retaining ring can also withstand significant axial force, ensuring the stability of the zipper placement plate 5 during rotation, thus ensuring that the zipper placement plate 5 will not shift during movement, thereby improving the accuracy and efficiency of sewing operations.
[0060] In addition to the zipper placement plate rotating connection structure disclosed in the above embodiments, this utility model also provides a placket machine including the above-mentioned zipper placement plate rotating connection structure. For the structure of other parts of the placket machine, please refer to the prior art, which will not be described in detail here.
[0061] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0062] 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.
