Description

Technical Field

[0001] This utility model relates to a template machine, and more particularly to a template machine dual-guide rail lead screw X-axis assembly. Background Technology

[0002] In modern textile processing and production, template machines are widely used, relying on their high efficiency for the processing and manufacturing of textiles such as clothing and footwear. The most important function of a template machine is the transfer of fabric, which requires extremely high stability and precision. Existing template machines commonly employ single-rail synchronous belt or single-rail lead screw coupling devices.

[0003] During use, both of the aforementioned devices revealed some problems. The single-rail structure, due to manufacturing and installation issues, often suffers from insufficient straightness, leading to deviations and affecting the sewing machine's accuracy. Furthermore, the single-rail structure is prone to deformation or wear over prolonged use, further reducing its accuracy. This not only makes material feeding unreliable and unstable but also affects product quality.

[0004] CN222846971U discloses a linear feeding device and a template machine. The linear feeding device includes a linkage plate, multiple sets of slide rails, and a drive mechanism. A slider is mounted on each slide rail and connected to the linkage plate. The actuating end of the drive mechanism has a motion seat, which is connected to the linkage plate. The motion seat, slide rails, and sliders are located on the same side of the linkage plate, and the connection position of the motion seat on the linkage plate is located between the projections of at least two slide rails on the linkage plate. This linear feeding device uses multiple sets of slide rails and optimizes the layout of the motion seat, slide rails, and sliders, effectively improving the feeding accuracy and stability of the template machine and overcoming the shortcomings of existing single-rail structures in terms of straightness and stability.

[0005] Although the aforementioned linear feeding device and template machine effectively solve the defects of existing single guide rail structures in terms of straightness and stability, since the drive mechanism and the linkage plate are only fixed by the motion seat, when the linkage plate is installed with a heavy structure or the device is used for a long time, the connection is prone to deformation, which causes the linkage plate to shift position and the transmission structure and guide rail structure to deform, affecting the stability and accuracy of the device structure. Utility Model Content

[0006] The purpose of this invention is to provide a double guide rail lead screw X-axis assembly for a template machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a double-guide rail lead screw X-axis assembly for a template sewing machine, comprising a power mechanism, a housing, a lead screw, a guide structure, and a fastening structure. The power mechanism is fixedly connected to one side of the housing, providing stable support; two sets of guide structures are fixedly connected vertically on the other side, forming a high-rigidity double-guide rail support structure, greatly improving torsional resistance and motion stability. The output end of the power mechanism extends into the housing and is fixedly connected to the lead screw, converting the rotational motion of the motor into high-precision linear motion. The output end of the lead screw is connected to a mounting plate via the fastening structure, and a template frame assembly is fixedly mounted on the other side of the mounting plate for directly performing sewing operations.

[0008] Preferably, the fastening structure includes an adapter plate, a steel strip, and steel strip pressure plates. One end of the adapter plate is fixedly connected to the output end of the lead screw, and the other end is used to connect to the mounting plate. The steel strip passes through the adapter plate, and both ends of the steel strip are fixed to the outer casing. This structure uses the steel strip to connect the transmission mechanism and the snap-on template frame assembly more tightly and securely, preventing deformation and damage to the guide rail and transmission mechanism caused by excessive weight or prolonged operation of the snap-on template frame connection. This makes the device structure more stable, ensures positioning accuracy, and extends the service life of the device. The steel strip pressure plates on both sides of the adapter plate are used to press and position the steel strip, ensuring its operational reliability.

[0009] Furthermore, the end face of the adapter plate near the lead screw is an arc-shaped end face, which allows the steel strip located in the channel to bulge, so that the steel strip exerts pressure on the adapter plate, making the device structure more robust and compact.

[0010] Preferably, the guide structure includes a guide rail and several sliders. The guide rail is fixed to the outer casing, and the sliders are slidably connected to the guide rail in the form of a sliding friction pair. The other side of the slider is fixedly connected to the mounting plate. This dual-guide-rail structure shares the load, effectively suppressing vibration and overturning moment during movement, and ensuring that the mounting plate always runs smoothly along a straight line.

[0011] Preferably, a proximity switch is installed on the upper end of the housing near the power mechanism, and correspondingly, a proximity switch sensor is fixed on the upper end of the mounting plate. Together, these two components can accurately detect the travel limits of the X-axis assembly, achieving precise soft-limit control, preventing overtravel collisions, and improving equipment safety and automation.

[0012] Preferably, the snap-on template frame assembly includes a snap-on template frame with claw clamp cylinder assemblies symmetrically installed at both ends in the horizontal direction for automatically clamping and releasing the fabric; the bottom is reinforced with a base plate fixing component to enhance the overall structural strength; and several T-shaped tees are fixed in the middle position for connecting and fixing various templates and clamps, thereby enhancing the scalability and adaptability of the function.

[0013] Preferably, the exposed part of the power mechanism is covered with a protective cover to prevent dust and impact, and extend the life of the motor; the two ends of the outer shell are fixed with end caps to seal the internal structure, prevent dust, lint and other foreign objects from entering the lead screw and guide rail, and ensure the long-term operating accuracy and reliability of the transmission mechanism.

[0014] Compared with existing technologies, this invention significantly improves the rigidity, smoothness of movement, and repeatability of the entire X-axis assembly by employing a high-precision lead screw drive combined with a double parallel guide rail structure. Furthermore, the unique steel strip fastening structure effectively resists the reverse torque generated by movement, preventing lead screw rotation and improving transmission efficiency and component lifespan. In addition, the protective cover, outer shell, and end cap together form a dustproof structure, ensuring the cleanliness of the lead screw's working environment.

Detailed Implementation

[0020] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0021] like Figures 1 to 3As shown, a template machine dual-guide rail 41 lead screw X-axis assembly mainly includes a power structure 1, a housing 2, a lead screw 3, a guide structure 4, and a fastening structure 5. The power structure 1 is fixedly installed on one side of the housing 2. This power structure 1 not only provides stable and efficient rotational power output for the entire system but also possesses high responsiveness and positioning accuracy. Two sets of guide structures 4 are symmetrically arranged vertically on the other side of the housing 2, forming a high-rigidity dual-guide rail 41 support system, significantly enhancing the overall structure's torsional resistance and motion stability. The output end of the power structure 1 is connected to the lead screw 3 located inside the housing 2. The lead screw 3 converts the precise rotational motion of the motor into smooth linear motion. The lead screw uses a ground high-precision ball screw, combined with a pre-tightened nut structure, effectively eliminating backlash and ensuring lag-free transmission and accurate and reliable positioning. The nut output end of the lead screw 3 is connected to a specially designed fastening structure 5, the other end of which is connected to a mounting plate 6. A template frame assembly 7 is bolted to the outside of the mounting plate 6, used to install and drive the sewing template to perform complex sewing tasks.

[0022] like Figure 3 As shown, the fastening structure 5 consists of an adapter plate 51, a steel strip 52, and a steel strip pressure plate 53. One end of the adapter plate 51 is fixedly connected to the lead screw nut, and the other end is connected to the mounting plate 6 by screws. The adapter plate 51 has a channel inside, through which the steel strip 52 passes, and its two ends are respectively anchored to the mounting seats at both ends of the outer shell 2. The steel strip 52 is used to connect the transmission mechanism and the snap-on template frame assembly 7 more tightly and securely, preventing deformation and damage to the guide rail 41 and lead screw 3 caused by excessive weight of the structure connected to the snap-on template frame assembly 7 or deformation and damage at the connection point due to long-term operation. This makes the device structure more stable, ensures positioning accuracy, and extends the service life of the device. The end face of the adapter plate 51 near the lead screw is an arc-shaped end face, which allows the steel strip 52 located in the channel to bulge, so that the steel strip 52 exerts pressure on the adapter plate 51, making the device structure more robust and tight. Steel strip pressure plates 53 are installed on both sides of the adapter plate 51. Pressure is applied by screws to firmly fix the position of the steel strip 52, preventing it from loosening or shifting and ensuring the reliability of torque transmission. The special structure of the channel in the fastening structure 5 also allows the steel strip 52 to make the connection between the lead screw 3 and the mounting plate 6 tighter, making the structure of the device more stable and reliable, and preventing vibrations generated during device operation from reducing the precision of the device.

[0023] like Figure 1Two sets of guide structures 4, arranged parallel to each other, are directly and parallelly installed at the upper and lower ends of the outer casing 2 on the side opposite to the power structure 1. Each guide structure 4 includes a guide rail 41 and several sliders 42. The guide rail 41 is fixed to the outer casing 2, and the sliders 42 are slidably connected to the guide rail 41. The other side of each slider 42 is fixedly connected to the mounting plate 6. This dual guide rail 41 layout can share the load, significantly suppressing the vibration and overturning moment generated during high-speed reciprocating motion, ensuring that the mounting plate 6 always runs smoothly and without drift along the predetermined trajectory, and greatly improving the repeatability accuracy of the sewing pattern.

[0024] like Figure 1 As shown, to achieve safe control of the travel end, a non-contact proximity switch 8 is installed on the upper end of the housing 2 near the motor. Correspondingly, a metal sensing plate 9 is fixed on the upper end of the mounting plate 6. The two work together to send a signal when the X-axis moves to its limit position, realizing a high-precision soft limit function, effectively avoiding mechanical collision accidents, and improving the automation level and operational safety of the whole machine.

[0025] like Figure 1 As shown, the snap-on template frame assembly 7 includes a main snap-on template frame 71, with claw clamp cylinder assemblies 72 symmetrically arranged at both ends in the horizontal direction, which can realize the rapid automatic clamping and release of the fabric; the bottom is enhanced by a reinforced base plate fixing component 73 to improve the overall rigidity and stability; and multiple standard T-shaped tee interfaces 74 are fixed in the middle area, which facilitates the expansion and installation of various special templates and clamps, significantly enhancing the applicability and multi-functionality of the equipment.

[0026] like Figure 1 As shown, the exposed part of the power structure 1 is covered with a protective cover 10 made of engineering plastic or metal, which can prevent dust and accidental impact, and extend the service life of the motor. The two ends of the outer shell 2 are sealed and fixed to the metal end cap 11 by sealing rings, which effectively prevents dust, lint and other common foreign objects in the workshop from entering the internal lead screw and guide rail 41 system, ensuring the long-term operating accuracy and reliability of the core transmission mechanism.

[0027] Through the above specific implementation methods, the template machine's dual-guide rail lead screw X-axis assembly adopts a high-precision lead screw drive combined with a dual parallel guide rail structure, firmly securing the mounting plate. This significantly improves the rigidity, smoothness of movement, and repeatability of the entire X-axis assembly. Furthermore, the unique steel belt fastening structure uses a steel belt to connect the transmission mechanism and the template frame assembly more tightly and securely, preventing deformation and damage to the guide rails and transmission mechanism caused by excessive weight or prolonged operation of the template frame connection. This makes the device structure more stable, ensures positioning accuracy, and extends the device's service life. The protruding structure at the connection point allows the steel belt to compress the fastening structure, making the structural connection between the guide structure and the mounting plate even tighter and more secure. In addition, the protective cover, outer shell, and end caps together form a dustproof structure, ensuring the cleanliness of the lead screw's working environment and preventing textile fibers, dust, and other foreign objects from entering the device, maintaining the high precision and long lifespan of the transmission system.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
