Description

Technical Field

[0002] The woven fabric has uneven edges on both sides, requiring edge trimming during winding. This necessitates using a cutting tool on the front side to cut the fabric across its width. Simultaneously, when a single sheet of fabric is folded into two layers and wound onto the winding roller, the fabric at the folds needs to be cut—a side cut. However, existing equipment can only perform one of these cutting methods, failing to simultaneously meet the demands of both front and side cuts. This limitation leads to low production efficiency and increases equipment costs and operational complexity. Utility Model Content

[0026] Reference Figures 1 to 2 The woven fabric cutting device of this utility model is illustrated in the following embodiments:

[0027] The woven fabric cutting device includes a cutting mechanism 100, an angle adjustment mechanism 200, a rotating structure 300, and a lateral movement structure 400. Compared with existing technologies, traditional equipment relies on fixed cutting blades and cannot achieve multi-dimensional position adjustment. This solution, through the coordinated action of the adjustable fixing structure of the support rod 210, the rotating connection component 230, and the lateral movement structure 400, enables the cutting mechanism 100 to achieve X / Y axis translation and rotation around the Z axis, thereby covering various cutting patterns. For example, when processing edge cutting of fabric rolls, the lateral movement structure 400 positions the blade to the edge area; when processing crease cutting, the rotating structure 300 adjusts the cutting plane to align with the fold line.

[0028] It should be noted that the above-mentioned mutually orthogonal X-axis, Y-axis and Z-axis are virtual settings for ease of description and do not specifically limit the present invention.

[0029] The cutting mechanism 100 refers to a component that achieves material separation through mechanical action, specifically using heat sealing or mechanical cutting tools. In this embodiment, the cutting mechanism 100 includes a heat sealing component, a cutting guide component, and a fixing frame 110. The heat sealing component includes a transducer 120 fixed to the fixing frame 110 and a blade holder 130 connected to the transducer 120. The blade holder 130 is located on the side of the transducer 120. The transducer 120 is configured to convert electrical energy into heat energy and release it through the blade holder 130. The transducer 120 is an energy conversion device that converts input electrical energy into heat energy, specifically using an ultrasonic transducer 120, which converts electrical energy into heat energy through high-frequency vibration. This device generates localized heat energy in the cutting mechanism 100 through high-frequency vibration, causing the woven fabric fibers to melt and form heat-sealed threads. Compared with traditional resistance heating methods, it has the advantages of precise temperature control and a small heat-affected zone.

[0030] The cutting guide assembly includes a connecting frame 140 fixedly connected to the fixed frame 110, a mold wheel 150 rotatably mounted within the connecting frame 140, and a blade 160 rotatably mounted at the bottom of the mold wheel 150. The mold wheel 150 and the blade holder 130 are correspondingly arranged so that after the woven fabric is heat-sealed between the blade holder 130 and the mold wheel 150, it is cut and separated by the blade 160 along the heat-sealing line. The blade holder 130 is a metal component that carries and transmits heat energy, and can be made of aluminum alloy. It heats the woven fabric by conducting the heat energy generated by the transducer 120. The mold wheel 150 is a rotating component with guide grooves, and can be a steel wheel with a hard chrome-plated surface. Its axial direction is perpendicular to the cutting plane of the blade 160, and it is used to guide the heat-sealing path of the woven fabric. The blade 160 is a cutting tool for cutting and separating the heat-sealed part, and can be a detachable ceramic blade. It moves synchronously with the mold wheel 150 by rotating.

[0031] Specifically, after the woven fabric is heat-sealed between the blade holder 130 and the die wheel 150, it is immediately cut along the heat-sealed line by the blade 160. During the heat-sealing process, the heat energy generated by the transducer 120 is transferred to the surface of the woven fabric through the blade holder 130. As the die wheel 150 rotates, it positions the woven fabric through the guide groove, keeping the heat-sealed line straight. The connecting frame 140 of the cutting guide assembly forms a linkage structure between the die wheel 150 and the blade 160. After the woven fabric is heat-sealed, the blade 160 rotates with the die wheel 150 and applies cutting force along the heat-sealed line, causing the heat-sealed part to separate. By integrating the heat-sealing and cutting functions in the same station, and utilizing the coordinated movement of the die wheel 150 and the blade 160, cutting is performed immediately after heat-sealing, avoiding errors caused by secondary positioning of the fabric, and reducing the occurrence of fraying and frayed edges in the woven fabric.

[0032] Furthermore, during installation, the cutting plane of the blade 160 is perpendicular to the axial direction of the mold wheel 150. When the cutting plane is perpendicular to the axial direction, the movement trajectory of the blade 160 forms an orthogonal cutting relationship with the rotation direction of the mold wheel 150, ensuring that the cutting line is always evenly distributed along the circumference of the mold wheel 150. Because the cutting plane is orthogonal to the axial direction of the mold wheel 150, the cutting trajectory formed by the blade 160 during rotation is consistent with the circumferential tangential direction of the mold wheel 150, allowing the cutting line to extend precisely along the heat-sealing line. This spatial relationship enables the blade 160 to maintain the cutting direction perpendicular to the fabric crease when cutting double-layered folded fabric, avoiding cutting path deviation.

[0033] Furthermore, during the cutting process of the heat-sealed woven fabric, the ceramic blade 160, in conjunction with the die wheel 150, generates shearing force, utilizing its material properties to maintain the sharpness of the cutting edge and prevent a decrease in cutting accuracy due to softening at high temperatures. The detachable structure can be implemented using bolt fixing, snap-locking, or sliding groove engagement, facilitating replacement when the blade 160 wears or when a change in cutting mode is required. The detachable structure allows operators to select different specifications of the blade 160 based on the thickness of the woven fabric or the shape of the cutting line, such as using ceramic blades 160 with different cutting angles or thicknesses to adapt to the cutting needs of single-layer or multi-layer fabrics. When the blade 160 wears, a new blade 160 can be replaced simply by loosening the locking device, without the need to completely disassemble the cutting mechanism 100.

[0034] Furthermore, it is proposed that the mounting bracket 110 is equipped with a cooling fan 170, which is correspondingly set with the transducer 120 and the tool holder 130.

[0035] Specifically, the cooling fan 170 is mounted on the mounting bracket 110, positioned within the same space as the heat-generating parts of the transducer 120 and the contact area of ​​the tool holder 130. When the transducer 120 is operating, heat is transferred to the cutting area through the tool holder 130. Simultaneously, the cooling fan 170 starts and generates directional airflow. This airflow passes over the surface of the transducer 120 housing and the connection point of the tool holder 130, quickly dissipating the accumulated heat outside the device. During this process, the operating parameters of the cooling fan 170 can be dynamically adjusted according to the operating status of the transducer 120, for example, by controlling the fan speed through feedback from a temperature sensor. This solution, by introducing the cooling fan 170, which directly corresponds to the heat source, achieves directional air cooling for critical heat-generating components, avoiding the risk of decreased cutting accuracy or component damage due to high temperatures.

[0036] The angle adjustment mechanism 200 includes a support rod 210 and a support base 220. The support base 220 has two spaced-apart support blocks 221, and the support rod 210 is threadedly connected to the two support blocks 221. The support rod 210 extends along the X-axis and is fixed to the two support blocks 221. The cutting mechanism 100 is rotatably fixed to the support rod 210 via a rotary connection assembly 230. In actual operation, the position of the blade 160 can be adjusted by rotating the support rod 210, so that the blade 160 corresponds to the cutting position of the woven fabric. Through the coordinated design of the double support blocks 221 and the threaded engagement, the adjustment process is convenient, and the multi-point locking improves the rigidity of the support rod 210, effectively solving the problem of reduced cutting accuracy caused by structural loosening.

[0037] The rotating connection assembly 230 includes a bearing sleeve, a locking bolt, and a rotating base. The bearing sleeve is fitted onto the support rod 210. The locking bolt penetrates the side wall of the bearing sleeve and abuts against the support rod 210. The rotating base is located on the outer surface of the bearing sleeve, and the cutting mechanism 100 is mounted on the rotating base. The locking bolt is a fastener that penetrates the side wall of the bearing sleeve. Specifically, it can be implemented using a combination structure with a threaded rod and a rotating handle. The contact pressure with the support rod 210 is adjusted by tightening. This component is used to fix the relative position of the bearing sleeve and the support rod 210 after angle adjustment, preventing the cutting mechanism 100 from shifting during operation.

[0038] When the cutting direction needs to be adjusted, the locking bolt is loosened to release the lock on the support rod 210, allowing the bearing sleeve to rotate freely around the axis of the support rod 210. After the operator rotates the cutting mechanism 100 along with the rotating base to the target angle, the locking bolt is retightened so that its end presses against the surface of the support rod 210, forming a friction lock. Through this structure, the cutting mechanism 100 can achieve arbitrary angular positioning within a 360° range in the same plane, for example, adjusting from a front cut perpendicular to the direction of fabric transmission to a side cut parallel to the crease line.

[0039] The lateral movement structure 400 includes a guide rail extending along the Y-axis, a base slidably mounted on the guide rail, and a drive unit for driving the base to slide. The guide rail is a linear guide structure extending along the Y-axis, which can be implemented using a linear guide rail or a sliding rail. Its function is to provide a stable movement path for the base, ensuring that the cutting mechanism 100 can accurately translate along the Y-axis. The sliding base is a moving component that cooperates with the guide rail, which can be implemented using a slider or roller assembly. It supports the rotating structure 300 and the angle adjustment mechanism 200, and moves along the guide rail under the drive of the drive unit. The drive unit is a power-providing device, which can be implemented using a servo motor in conjunction with a ball screw, synchronous belt drive, or rack and pinion mechanism. Its function is to drive the base to adjust its position according to a preset stroke through power output.

[0040] When the cutting position needs to be adjusted, the drive unit starts and drives the base to move along the guide rail through the transmission mechanism, thereby causing the rotating structure 300 and the angle adjustment mechanism 200 fixed on the base to translate as a whole along the Y-axis. This translational movement enables the cutting mechanism 100 to cover different cutting areas of the woven fabric, such as moving from the edge of the fabric to the crease position, or adjusting the cutting path according to the width of the fabric.

[0041] Furthermore, a rotating structure 300 is proposed, including a rotating drive unit for driving the support base 220 to rotate around the Z-axis. When cutting the fabric edge, the rotating drive unit controls the support base 220 to maintain its initial angular position, ensuring the cutting mechanism 100 is directly facing the edge of the woven fabric. When cutting between layers of folded fabric is required, the rotating drive unit drives the support base 220 to rotate around the Z-axis by a set angle, such as 90 degrees or other predetermined angle, causing the cutting mechanism 100 to turn towards the side cutting direction. During this process, the lateral movement structure 400 synchronously controls the rotating structure 300 to move along the Y-axis, ensuring the blade 160 is always aligned with the cutting line. This application resolves the technical contradiction of existing equipment being unable to simultaneously handle edge cutting and interlayer cutting. Through axial rotation control, a single cutting mechanism 100 achieves compatible operation for both cutting modes, avoiding space waste and operational complexity caused by repeated installation of cutting devices, and effectively improving equipment integration and cutting efficiency.

[0042] The rotary drive unit refers to the device that provides rotational power, which can be implemented by using a stepper motor or servo motor in conjunction with a reducer. Its output shaft is connected to the support base 220 through a coupling to achieve torque transmission. The Z-axis refers to the vertical axis perpendicular to the horizontal plane, which can be determined by the coordinate system definition method. When the support base 220 rotates around this axis, it drives the cutting mechanism 100 to adjust its direction in the horizontal plane.

[0043] In summary, during the processing, the operator can adjust the X / Y axis displacement and rotation angle according to the cutting requirements to switch between front and side cutting modes, enabling dual cutting of the woven fabric edge and creases without changing equipment. The combined use of the angle adjustment mechanism 200 and the lateral movement structure 400 allows for precise control of the tool's spatial position, avoiding efficiency losses caused by repeated disassembly and reassembly of the equipment.
