Description

Technical Field

[0001] This utility model belongs to the technical field of fabric cutting equipment, specifically relating to a quick connector device for fabric cutting equipment. Background Technology

[0002] In fabric cutting and processing, such as the production of terry cloths or dishcloths, continuous cutting of rolls or batches of fabric is usually required. When a batch of fabric is cut or a roll of fabric is used up, the end of the fabric needs to be joined to the beginning of a new roll to maintain production continuity. Traditionally, this joining operation is done manually by workers on a sewing machine: first, the cutting equipment is paused, then the ends of the fabric are aligned and sewn together. This manual operation is inefficient, not only increasing production time but also easily leading to uneven joints due to operational errors, affecting fabric quality and subsequent processing. Utility Model Content

[0003] The purpose of this invention is to provide a quick connector device for fabric cutting equipment to improve connector efficiency and reduce problems such as uneven connectors.

[0004] To achieve the above objectives, the technical solution specifically provided by this utility model is as follows: A quick-connector device for fabric cutting equipment, comprising: frame; A fabric end clamping mechanism is mounted on the frame and is used to clamp the beginning and end of the fabric. The fabric end clamping mechanism includes a fixed crossbeam arranged along the width of the fabric and a movable crossbeam located above the fixed crossbeam, as well as a driving component. The driving component is used to drive the movable crossbeam to move relative to the fixed crossbeam so that the movable crossbeam separates from or clamps the fixed crossbeam. A sewing mechanism, mounted on a frame, includes a connecting functional part located on one side of the fabric end clamping mechanism and movable along the length of a fixed crossbeam, for sewing the ends of the fabric clamped in the fabric end clamping mechanism.

[0005] The "fixed crossbeam" and "moving crossbeam" of this invention are arranged along the entire width of the fabric, forming a dedicated clamping station. The driving component drives the moving crossbeam downwards, clamping the entire width of the fabric in one go, ensuring stability and reliability. Two pieces of fabric are placed end-to-end between the crossbeams; after clamping, the fabric position is firmly locked, providing a precise and stable foundation for subsequent automated sewing. The sewing mechanism is directly mounted on the same frame and located on one side of the fabric end clamping mechanism. This allows the splicing process to be seamlessly integrated into the cutting equipment, eliminating the need for fabric disassembly and handling, significantly reducing process changeover time. The connecting function can move along the length of the fixed crossbeam (i.e., the fabric width direction), automatically completing the sewing work across the entire splice width, completely replacing the manual operation of workers foot-operated sewing machines and hand-pushing the fabric. This not only results in higher speed but also consistent and reliable sewing quality.

[0006] The "sewing mechanism" of this utility model refers to a device capable of connecting the ends of fabric through continuous stitches or other connection methods. The mechanism includes a connecting functional part (such as a sewing machine head or ultrasonic welding head) and a moving execution component (such as an electric slide or robotic arm) that drives the connecting functional part to move along the length of a fixed crossbeam. The moving execution component is fixedly connected to the connecting functional part.

[0007] To achieve automated sewing across the entire joint width, the sewing mechanism, fabric end clamping mechanism, and frame are configured as follows: The moving execution component of the sewing mechanism is mounted on the frame, and its moving trajectory is parallel to the length direction of the fixed crossbeam; the connecting function part is set on the moving part of the moving execution component; the drive motor of the moving execution component and the connecting function part (such as the motor of the sewing machine head) are electrically connected to the power source and operating circuit of the equipment.

[0008] Once the fabric is clamped and fixed by the fabric clamping mechanism, the operator triggers the equipment start switch, activating the drive motor of the moving actuator, which in turn moves the connecting functional unit at a constant speed parallel to the fixed crossbeam. Simultaneously, the connecting functional unit performs a connecting operation (like the up-and-down movement of a sewing machine needle) under its motor drive. Because the moving trajectory of the moving actuator is set parallel to the fixed crossbeam, and the connecting functional unit works synchronously with it, the connecting functional unit can automatically form a continuous connecting stitch across the entire width of the clamped fabric.

[0009] Furthermore, the direction parallel to the length of the fixed crossbeam is defined as the X direction, and the connecting functional part can also move along the Y direction and / or the Z direction, both of which are perpendicular to the X direction and the Y direction is perpendicular to the Z direction.

[0010] Furthermore, the connecting function unit is moved via an electric slide or a robotic arm.

[0011] Furthermore, the sewing mechanism includes a cutter for cutting off excess fabric at the ends during sewing.

[0012] Furthermore, the driving component is any one of a cylinder, a hydraulic cylinder, or an electric push rod.

[0013] Furthermore, the fixed crossbeam and / or the movable crossbeam are provided with an anti-slip pad layer.

[0014] The quick-connect device provided by this utility model, through the coordinated arrangement of a fabric end clamping mechanism and a directionally movable sewing mechanism, has the following beneficial effects: 1. Achieved efficient and continuous automated sewing: The fabric end clamping mechanism, set along the fabric width direction, can quickly and once clamp and fix the entire width of fabric ends, providing a stable foundation for automated sewing. Combined with a sewing mechanism that can move along the length of the fixed beam (i.e., the fabric width direction), it realizes automatic and continuous sewing of the entire joint width, completely replacing the traditional inefficient manual operation, greatly improving sewing efficiency and significantly reducing equipment downtime.

[0015] 2. Ensures the flatness and stability of the joint quality: The fabric clamping mechanism (especially when used with the anti-slip pad) effectively prevents the fabric from loosening or shifting during the sewing process, ensuring the alignment accuracy at the joint. Simultaneously, the sewing mechanism performs mechanized sewing along a preset straight trajectory, avoiding common problems such as skewing and skipped stitches found in manual sewing. This results in straight, strong, and consistent stitches at the joint, effectively improving the overall quality of the fabric.

[0016] 3. Compact structure and high integration: The clamping and sewing functions are integrated into the same frame, so that the splicing operation can be completed directly on the cutting equipment. This eliminates the cumbersome steps of disassembling the fabric, transporting it to a separate sewing machine and then reassembling it, thus optimizing the production process and saving operating space and time.

[0017] 4. Highly versatile and practical: By setting a cutting blade, excess fabric at the ends can be automatically trimmed during sewing, achieving one-step sewing and finishing, further improving work efficiency and the aesthetics of the joints. Furthermore, the sewing mechanism's ability to move in the X, Y, and Z directions gives it better adaptability, enabling it to handle fabrics of different thicknesses and processing requirements.

[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the following will be described in conjunction with the appendix. Figure 1-5 This application will be described in further detail.

[0021] A quick coupling device for fabric cutting equipment, as shown in the reference. Figure 1 and Figure 2 It includes frame 1, fabric end clamping mechanism and sewing mechanism.

[0022] The frame 1, serving as the main support for the entire device, can be welded or assembled from square steel or aluminum profiles. Its specific structure includes a main body 11, a pair of uprights 12 located on one side of the top of the main body 11, and several mounting beams 13 for installing other functional components. This embodiment does not limit the specific form of the frame 1; those skilled in the art can make adaptive adjustments based on the layout of the actual production site.

[0023] The fabric clamping mechanism is the core component of this invention, enabling rapid and stable clamping. (Refer to...) Figure 1 and Figure 2 The mechanism mainly includes a fixed crossbeam 2, a movable crossbeam 3, and a drive component 31. Both the fixed crossbeam 2 and the movable crossbeam 3 are arranged along the width of the fabric and are vertically opposed to each other.

[0024] The fixed crossbeam 2 is fixed to the column 12 at both ends by mounting crossbeam 13. To improve the clamping effect and protect the fabric, the top surface of the fixed crossbeam 2 is fitted with an anti-slip pad 21. This design can effectively increase friction, prevent the fabric from slipping, and avoid scratching the fabric due to hard contact.

[0025] The drive component 31 provides the driving force to move the movable crossbeam 3 up and down. Those skilled in the art can select linear drive elements such as cylinders, hydraulic cylinders, or electric push rods according to actual needs. In this embodiment, the drive component 31 is preferably a cylinder, with its cylinder body fixed to the mounting crossbeam 13 at the top of the column, and the piston rod connected to the movable crossbeam 3. When the drive component 31 pushes the movable crossbeam 3 downwards, the movable crossbeam 3 and the fixed crossbeam 2 work together to press the ends of the fabric placed between them together; when the drive component 31 moves the movable crossbeam 3 upwards, the two separate, forming an opening for inserting the fabric.

[0026] The suturing mechanism is the key component for achieving automated suturing. (Refer to...) Figures 1 to 3 The mechanism mainly consists of a moving actuator and a connecting function unit.

[0027] In this embodiment, an XYZ three-axis electric slide table 41 is preferably used as the moving actuator, and its base is fixedly mounted on the frame body 11. This electric slide table 41 is responsible for driving the connecting functional unit to move precisely in three-dimensional space.

[0028] The connecting function is an industrial sewing machine head 4. This sewing machine head 4 is fixed to the slide of the electric slide table 41 by a mounting plate. The motors of each axis of the electric slide table 41 and the motor of the sewing machine head 4 are all connected to the main control circuit of the equipment via cables.

[0029] After the fabric is clamped and fixed by the fabric clamping mechanism, the operator triggers the start switch. At this time, the drive motor of the electric slide table 41 starts, driving the sewing machine head 4 to move at a constant speed along a direction parallel to the length of the fixed crossbeam 2 (i.e., the X direction). At the same time, the sewing machine head 4 performs sewing operations synchronously under the drive of its own motor. Since the movement trajectory is consistent with the width direction of the fabric, the sewing machine head 4 is able to automatically sew a continuous, straight stitch across the entire width of the clamped fabric.

[0030] Reference Figure 3 To further improve the quality of the joint and the degree of automation, the sewing machine head 4 also integrates the following components: a cutter 42, which is set on one side of the needle and is used to automatically cut off the excess part of the fabric end while sewing, so that the joint is flatter and more beautiful.

[0031] Metal guide plate 43 is located on the body of the sewing machine head 4 on the fabric feed side and extends downward at an angle. Its function is to guide the beginning and end of the fabric smoothly into the needle area, ensuring the reliability of the sewing start.

[0032] To ensure operational safety and accuracy, mechanical or inductive limit switches (not shown in the figure) can be installed at both ends of the X-axis travel of the electric slide 41 to limit the movement range of the sewing mechanism at the hardware level and achieve automatic start and stop. In addition, the motion actuator can also be replaced with a robotic arm with equivalent functions.

[0033] Reference Figure 1 and Figure 2 To form a complete production line, a fabric conveying mechanism can be installed on one side of the frame 1. This mechanism and the sewing mechanism are located on opposite sides of the column 12. It mainly includes a driven roller 6 and a driving roller 5, both of which are rotatably mounted on the mounting beam 13 of the frame via bearing seats. A motor 51 drives the driving roller 5 to rotate via a transmission belt 52, thereby achieving continuous fabric conveying.

[0034] Working principle: Reference Figure 4 and Figure 5 Align the two pieces of fabric α that need to be joined end to end, place them between the opened fixed beam 2 and the movable beam 3, ensuring the ends to be sewn protrude appropriately. Activate the drive unit 31, causing the movable beam 3 to move downwards, working in conjunction with the fixed beam 2 to firmly clamp the ends of the fabric. Trigger the start switch, and the sewing mechanism operates according to the preset program. Driven by the electric slide table 41, the sewing machine head 4 moves along the X direction, simultaneously completing continuous sewing and edge trimming across the entire width of the fabric α. After sewing is complete, the drive unit 31 moves the movable beam 3 upwards to release the fabric. Subsequently, the fabric conveying mechanism starts, transporting the joined fabric α to the next workstation, completing the entire joining process.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
