Description

Technical Field

[0001] This utility model belongs to the field of fabric cutting machine technology, and in particular relates to a high-efficiency fabric cutting machine. Background Technology

[0002] A fabric cutting machine, also known as a fabric trimming machine, is an industrial device specifically designed for the efficient and precise cutting of textile fabrics. Its core function is to quickly and neatly cut large rolls of greige fabric, finished fabric, or other textiles to a preset length or according to instructions, providing fabric pieces of the required size for subsequent sewing, processing, or inspection processes. The pressure plate, as an important component of the fabric cutting machine, is responsible for fixing the fabric during the cutting process, ensuring the stability and accuracy of the cut.

[0003] Currently, there are two main types of fabric cutting machine pressing plates: integral flat plate and single roller type. The integral flat plate uses a single flat plate pressed onto the fabric surface, applying pressure through mechanical or pneumatic devices. Its structure is simple and manufacturing cost is low. However, due to the integral pressure, it easily forms indentations on the fabric surface, especially noticeable on thin and soft fabrics. Furthermore, the integral flat plate may cause uneven pressure distribution when the fabric thickness is uneven, affecting cutting quality. In contrast, the single roller type provides more uniform pressure to the fabric compared to the integral flat plate. However, its line contact pressure is too high, creating "knife-cut" indentations on thin fabrics. Moreover, it may not provide sufficient pressure for thicker fabrics or at higher cutting speeds, leading to fabric displacement or inaccurate cutting.

[0004] Therefore, this utility model provides a high-efficiency fabric cutting machine to solve the problems existing in the prior art. Utility Model Content

The Y-axis drive motor is located on one side of the Y-axis moving housing, and the output end of the Y-axis drive motor is connected to the Y-axis driven assembly.

[0011] Furthermore, the Y-axis driven assembly includes a Y-axis driven belt, a third driven shaft, and a fourth driven shaft. The third and fourth driven shafts are respectively located below the output end of the Y-axis drive motor, and the third and fourth driven shafts are arranged in a triangle with the output end of the Y-axis drive motor. The two ends of the Y-axis driven belt are fixedly connected to the X-axis moving housing, and the Y-axis driven belt passes around the third driven shaft, the fourth driven shaft, and the output end of the Y-axis drive motor.

[0012] Furthermore, the Z-axis moving component includes a Z-axis drive motor, a ball screw, a Z-axis support member, a Z-axis limiting member, a Z-axis support plate, and auxiliary support columns. Both ends of the ball screw are connected to the Z-axis limiting member.

[0015] Compared with existing technologies, the beneficial effects of this utility model patent are as follows: This utility model patent replaces the traditional integral pressure plate with columnar contact points, reducing the pressure area on the fabric and avoiding fiber structure deformation caused by continuous large-area pressure. The gaps between the columns provide lateral deformation release space for high-elastic fabrics (such as spandex blends), preventing permanent indentations after stretching and rebound. Independent columns can respond to fabric surface undulations (such as seams and jacquard patterns), maintaining balanced pressure and avoiding sudden pressure increases caused by local bulges in hard pressure plates. For highly sensitive materials such as thin silk and functional coated fabrics, discrete contact can also maximize the protection of surface smoothness and coating integrity. The columnar arrangement forms an air circulation channel, reducing frictional heat buildup between the fabric and the pressure plate during high-speed cutting and preventing thermoplastic fibers from melting and sticking together. X-axis slide rail displacement ensures that the cutting mechanism moves accurately along the fabric width direction, adapting to different fabric width requirements. Y-axis displacement allows the cutting head to cut laterally into any position on the fabric, breaking through the limitation of traditional fabric cutting machines that can only cut at the ends. The Z-axis lifting mechanism dynamically controls the cutting pressure, enabling flexible switching between "light touch cutting" and "heavy pressure penetration" to reduce burrs on the cut edges. The three-axis linkage capability allows the cutting mechanism to execute non-linear trajectories (such as arcs and serrated lines), meeting the processing needs of special cut pieces (such as curved hems of clothing and irregularly shaped parts of composite materials).

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] See Figure 1 As shown, this embodiment provides a high-efficiency fabric cutting machine, including: a fabric feeding table 1, with X-axis slide rails on both sides of the fabric feeding table 1, a displacement mechanism 2 slidably connected to the slide rails, a cutting mechanism 3 fixedly connected to the displacement mechanism 2, and a multi-column fabric pressing mechanism 4 fixedly connected to both sides of the displacement mechanism 2, the multi-column fabric pressing mechanism 4 being perpendicular to the X-axis slide rails.

[0026] In some embodiments of this application, see Figure 2 As shown, where Figure 2The multi-column pressing mechanism 4 is not shown in the diagram. The multi-column pressing mechanism 4 would obstruct the structure of the displacement mechanism 2, therefore... Figure 2 Not displayed in the text, please refer to the following: Figure 1 The multi-column pressing mechanism 4 is located in the middle. The displacement mechanism 2 includes an X-axis displacement component 201, a Y-axis displacement component 202, and a Z-axis displacement component 203. The X-axis displacement component 201 is slidably connected to the X-axis slide rail and is used to drive the cutting mechanism 3 to move along the X-axis slide rail direction. The Y-axis displacement component 202 is fixedly connected to the X-axis displacement component 201. The Y-axis displacement component 202 is fixedly connected to the Z-axis displacement component 203. The Z-axis displacement component 203 is fixedly connected to the cutting mechanism 3. The Y-axis displacement component 202 is used to drive the cutting mechanism 3 to move between the two X-axis slide rails. The Z-axis displacement component 203 is used to drive the cutting mechanism 3 to move in the vertical direction of the X-axis slide rail.

[0027] Specifically, the fabric feeding table 1 is used to place the fabric to be cut on it. The displacement mechanism 2 can realize the displacement of the X, Y and Z axes. The multi-column pressing mechanism 4 presses the fabric tightly to prevent it from sliding.

[0028] Understandably, replacing the traditional integral pressure plate with columnar contact points reduces the fabric's pressure area, preventing fiber structure deformation caused by continuous large-area pressure. The gaps between the columns provide lateral deformation release space for high-elastic fabrics (such as spandex blends), preventing permanent indentations after stretching and rebound. Independent columns can respond to fabric surface undulations (such as seams and jacquard patterns), maintaining balanced pressure and preventing sudden pressure increases caused by localized protrusions on rigid pressure plates. For highly sensitive materials such as lightweight silk and functional coated fabrics, discrete contact can also maximize the protection of surface smoothness and coating integrity. The columnar arrangement forms air circulation channels, reducing frictional heat buildup between the fabric and the pressure plate during high-speed cutting and preventing thermoplastic fibers from melting and sticking together. X-axis slide rail displacement ensures that the cutting mechanism 3 moves precisely along the fabric width direction, adapting to different fabric width requirements. Y-axis displacement allows the cutting head to cut laterally into any position on the fabric, breaking through the limitation of traditional fabric cutting machines that can only cut at the ends. The Z-axis lifting mechanism dynamically controls the cutting pressure, enabling flexible switching between "light touch cutting" and "heavy pressure penetration" to reduce the burr rate of the cut edges. The three-axis linkage capability allows the cutting mechanism 3 to execute non-linear trajectories (such as arcs and serrated lines), meeting the processing needs of special cut pieces (such as the curved hem of clothing and irregularly shaped parts of composite materials).

[0029] In some embodiments of this application, see Figure 3As shown, the X-axis displacement component 201 includes an X-axis driven assembly, an X-axis drive motor 2011, an X-axis smoothing wheel 2012, an X-axis moving housing 2013, and an X-axis displacement inner housing. The two ends of the X-axis driven assembly are fixedly connected to the two ends of the feeding table 1, and the X-axis driven assembly is located above the X-axis slide rail. The X-axis moving housing 2013 and the X-axis displacement inner housing are respectively located on both sides of the X-axis slide rail. The X-axis moving housing 2013 and the X-axis displacement inner housing are fixedly connected by bolts. Several X-axis smoothing wheels 2012 are rotatably connected to the bolts. The several X-axis smoothing wheels 2012 are located between the X-axis driven assembly and the X-axis slide rail, and the several X-axis smoothing wheels 2012 abut against the X-axis driven assembly and the X-axis slide rail. The X-axis drive motor 2011 is located on one side of the X-axis moving housing 2013, and the output end of the X-axis drive motor 2011 is connected to the X-axis driven assembly.

[0030] In some embodiments of this application, the X-axis driven assembly includes an X-axis driven belt 2015, a first driven shaft 2016, and a second driven shaft 2017. The first driven shaft 2016 and the second driven shaft 2017 are respectively located below the output end of the X-axis drive motor 2011, and the first driven shaft 2016 and the second driven shaft 2017 are arranged in a triangle with the output end of the X-axis drive motor 2011. The two ends of the X-axis driven belt 2015 are fixedly connected to the two ends of the feed table 1, and the X-axis driven belt 2015 passes around the first driven shaft 2016, the second driven shaft 2017, and the output end of the X-axis drive motor 2011.

[0031] Specifically, when displacement is required, the X-axis drive motor 2011 rotates, while the X-axis driven belt 2015 remains stationary. Therefore, by rotating the X-axis drive motor 2011, in conjunction with the first driven shaft 2016 and the second driven shaft 2017, the X-axis moving outer shell 2013 and the X-axis displacement inner shell are driven to achieve displacement in the X-axis direction. At the same time, the X-axis smoothing wheel 2012 is used to achieve smooth movement.

[0032] Understandably, by adopting a reverse transmission mode combining a fixed reference belt and a moving drive unit, the two ends of the X-axis driven belt 2015 are firmly anchored to the body of the feed table 1, forming a highly stable spatial reference track. The drive motor is directly integrated onto the moving component, and its output end, together with the first driven shaft 2016 and the second driven shaft 2017, forms a triangular force couple balance layout, which resolves the torsional effect of the working torque on the displacement mechanism 2, ensuring that the driving force is accurately transmitted along the slide rail axis, and eliminating the error accumulation of multi-stage transmission chains from the root. The displacement outer shell and the displacement inner shell are rigidly connected across the track by bolts, constructing a closed anti-torsional frame structure, which enhances the ability to resist cutting lateral loads. At the same time, the array-distributed X-axis smooth wheels 2012 form continuous rolling contact at the interface between the driven component and the slide rail, converting concentrated loads into uniformly distributed support forces. This not only fills the microscopic uneven areas of the track, but also converts sliding friction into low-resistance rolling, suppressing the sticky crawling phenomenon common in high-speed operation. The fixed-tension driven belt maintains a constant shape, avoiding the elastic deformation and slack vibration caused by the reciprocating bending of traditional transmission belts. The integrated design of the drive motor and moving components significantly reduces the moment of inertia, making the displacement start and stop response more rapid and sensitive. The pure rolling operation mode of the smooth wheel set not only eliminates the risk of friction dust contaminating the fabric, but also absorbs high-frequency vibrations from the track through the synergistic action of multiple wheels, reducing equipment operating noise. The symmetrically arranged outer and inner shell structures further offset inertial impacts, ensuring stability under high-speed conditions. Crucially, the triangularly arranged driven shaft system forms a self-balancing force system, automatically neutralizing the radial component force generated during the drive process, ensuring that the displacement trajectory always strictly follows the guide axis of the slide rail, establishing a geometric benchmark for precision cutting. The open shaft system layout provides an intuitive and visible maintenance window, and the split shell design allows for convenient and non-destructive opening and closing via bolt connections, eliminating the need for complete machine disassembly for wheel system maintenance and component replacement, greatly improving equipment maintainability. The smooth rollers and the contact surface make pure rolling contact, eliminating sliding wear and extending the service life of key moving parts. The modular architecture allows for independent maintenance of single-sided slide rail systems, minimizing equipment downtime.

[0033] In some embodiments of this application, see Figure 4As shown, the Y-axis displacement component 202 includes a Y-axis driven assembly, a Y-axis drive motor 2021, a Y-axis smooth wheel 2022, a Y-axis moving housing 2023, and a Y-axis displacement inner housing 2024. The two ends of the Y-axis driven assembly are fixedly connected to the X-axis moving housing 2013, and the Y-axis driven assembly is located above the Y-axis slide rail 2028. The Y-axis moving housing 2023 and the Y-axis displacement inner housing 2024 are respectively located on both sides of the Y-axis slide rail 2028. 23 is fixedly connected to the Y-axis displacement inner shell 2024 by bolts. Several Y-axis smooth wheels 2022 are rotatably connected to the bolts. The several Y-axis smooth wheels 2022 are located between the Y-axis driven component and the Y-axis slide rail 2028, and the several Y-axis smooth wheels 2022 abut against the Y-axis driven component and the Y-axis slide rail 2028. The Y-axis drive motor 2021 is located on one side of the Y-axis moving outer shell 2023, and the output end of the Y-axis drive motor 2021 is connected to the Y-axis driven component.

[0034] In some embodiments of this application, the Y-axis driven assembly includes a Y-axis driven belt 2025, a third driven shaft 2026, and a fourth driven shaft 2027. The third driven shaft 2026 and the fourth driven shaft 2027 are respectively located below the output end of the Y-axis drive motor 2021, and the third driven shaft 2026 and the fourth driven shaft 2027 are arranged in a triangle with the output end of the Y-axis drive motor 2021. The two ends of the Y-axis driven belt 2025 are fixedly connected to the X-axis moving housing 2013, and the Y-axis driven belt 2025 passes around the third driven shaft 2026, the fourth driven shaft 2027, and the output end of the Y-axis drive motor 2021.

[0035] Understandably, the Y-axis driven belt 2025 is fixed at both ends to the X-axis moving housing, forming a stable reference track spanning the width of the equipment. The drive motor is directly integrated into the moving housing, and its output end, together with the third driven shaft 2026 and the fourth driven shaft 2027, forms a triangular force system layout, reducing the torsional effect of the working torque on the cantilever structure and ensuring precise transmission of driving force along the slide rail axis. The displacement housing and the displacement inner housing are rigidly connected across the track by bolts, constructing a closed anti-torsional frame to suppress lateral vibration during cutting operations. The arrayed Y-axis smooth wheels 2022 establish a continuous rolling contact interface between the driven components and the slide rail, transforming concentrated loads into uniformly distributed support. This compensates for the microscopic unevenness of the track and transforms sliding friction into low-resistance rolling, completely eliminating the viscous lag phenomenon during high-speed reversal. The fixedly tensioned Y-axis driven belt 2025 always maintains geometric constancy, avoiding the elastic deformation caused by the reciprocating bending of traditional traction belts. The integrated design of the drive unit and the moving components significantly reduces the moment of inertia, giving the cutting head a rapid start-stop response capability. The smooth wheel assembly's pure rolling operation mode not only eliminates frictional dust pollution of the clean environment but also improves the equipment's acoustic performance by absorbing high-frequency vibration energy through multi-wheel synergistic damping. The self-balancing force system formed by the triangular shaft layout automatically neutralizes the radial component, ensuring that the displacement trajectory strictly follows the guide axis, establishing a geometric benchmark for complex curve cutting. Especially in cantilever conditions, the double-shell structure suppresses off-center deformation through symmetrical constraints, maintaining the accuracy of the tool's center point position.

[0036] In some embodiments of this application, the Z-axis moving component includes a Z-axis drive motor 2031, a lead screw 2033, a Z-axis support 2032, a Z-axis limiting component 2034, a Z-axis support plate 2035, and an auxiliary support column 2036. Both ends of the lead screw 2033 are connected to the Z-axis limiting component 2034. The Z-axis drive motor 2031 is located at the top of the Z-axis displacement component 203, and its output end is fixedly connected to the lead screw 2033. Auxiliary support columns 2036 are provided on both sides of the ball screw 2033, and the auxiliary support columns 2036 pass through several Z-axis support members 2032 and are connected to Z-axis limiting members 2034. Several Z-axis support members 2032 are provided between the two Z-axis limiting members 2034. Several Z-axis support members 2032 are fixedly connected to the Y-axis moving housing 2023. Z-axis support plate 2035 is fixedly connected to the two Z-axis limiting members 2034. A cutting mechanism 3 is fixedly connected to the Z-axis support plate 2035.

[0037] In some embodiments of this application, the cutting mechanism 3 includes a cutting motor 301, a cutting blade 302, a torsion spring 303, a cutting guard plate 304, and a shock-absorbing column 305. The cutting guard plate 304 is fixedly connected to the Z-axis support plate 2035. The cutting motor 301 is fixedly connected to the top of the cutting guard plate 304. The output end of the cutting motor 301 is fixedly connected to the cutting blade 302. Shock-absorbing columns 305 are provided on both sides of the cutting blade 302. The torsion spring 303 is sleeved on the shock-absorbing column 305.

[0038] Specifically, the Z-axis drive motor 2031 rotates, causing the Z-axis moving parts to move along the Z-axis on the ball screw 2033, while the cutting motor 301 rotates, causing the cutting tool 302 to cut the fabric.

[0039] Understandably, the ball screw, as the main transmission element, is constrained at both ends by limiting components to form a stable reference axis. The Z-axis drive motor 2031 is directly connected to the top of the screw to achieve zero-backlash power transmission. The auxiliary support columns 2036 arranged in parallel on both sides penetrate all the support components to form a closed-loop force flow path, which not only bears lateral loads but also suppresses screw buckling under pressure. The multi-support layout between the double limiting components enhances bending stiffness. The Z-axis support plate 2035, as the mounting base of the cutting mechanism 3, is rigidly connected to the limiting components to ensure the shortest force transmission path, allowing the downward pressure of the tool to be directly introduced into the main frame instead of being transmitted through the screw, thus ensuring transmission accuracy and lifespan from the root. The threaded pair of the ball screw converts rotational motion into linear displacement, achieving repeatable positioning capability. The parallel guiding effect of the double auxiliary support columns 2036 eliminates the radial backlash of the traditional single screw system, maintaining the vertical trajectory of the cutting head without drift. Especially in high-speed piercing conditions, the damping effect of the auxiliary columns absorbs instantaneous impact energy, preventing fabric displacement caused by mechanism oscillation. The cutting guard plate 304 serves as a load-bearing base and is flexibly connected to the Z-axis support plate 2035 via the shock-absorbing column 305. The preload of the torsion spring 303 balances the weight of the cutter while providing controllable following, so that the blade generates a buffer effect the moment it contacts the fabric, which maintains a constant cutting speed and avoids hard impact damage to sensitive fabrics.

[0040] In some embodiments of this application, see Figure 5 As shown, the multi-column pressing mechanism 4 includes pressing columns 401, auxiliary pressing components 402, transverse support columns 403, connectors 404, and pressing shaft 405. The two ends of the pressing shaft 405 are fixedly connected to the X-axis moving housing 2013. Connectors 404 are provided on the pressing shaft 405. Transverse support columns 403 are fixedly connected to the connectors 404. Several transverse support columns 403 are provided. Several pressing columns 401 are fixedly connected to the several transverse support columns 403. Gaps are left between the several pressing columns 401. Auxiliary pressing components 402 are fixedly connected to both sides of the pressing columns 401.

[0041] Understandably, the pressing shaft 405, as the basic load-bearing component, is rigidly anchored at both ends to the outer shell of the displacement mechanism 2, forming a stable force transmission backbone. The connector 404 modularly distributes the transverse support columns 403 onto the pressing shaft 405, achieving lateral extension of pressure distribution. Multiple parallel transverse support columns 403 constitute a secondary load-bearing frame, providing a uniform support base for the array of pressing columns 401. The pressing columns 401 are fixed to the transverse support columns 403 in a discrete lattice configuration, with pre-reserved physical gaps between the columns forming airflow channels and deformation release spaces. Auxiliary pressing components 402 are symmetrically distributed on both sides of the main pressing columns 401, forming edge constraint reinforcement bands. This hierarchical structure reconstructs the pressure transmission path, allowing the mechanical load to be progressively softened and transmitted along the path of pressing shaft 405 - connector 404 - transverse support columns 403 - pressing columns 401. Discretely distributed pressure columns 401 transform the full-area contact of traditional integral pressure plates into multi-point precise pressure application, reducing pressure per unit area and avoiding the risk of indentation on highly sensitive fabrics (such as silk satin and functional coated fabrics). The gaps between the columns provide lateral deformation release channels for high-elasticity fabrics, preventing irreversible stretching of materials such as spandex blends due to full-area constraint. Auxiliary pressure components 402 reinforce constraint on the fabric edge areas, suppressing edge curling in knitted fabrics and preventing edge fiber breakage due to excessive pressure. The parallel layout of the lateral support columns 403 endows the system with local adaptive capabilities; when a single column encounters a seam or texture protrusion, adjacent columns maintain stable pressure, eliminating the full-area pressure fluctuations caused by localized lifting in traditional pressure plates.

[0042] The high-efficiency fabric cutting machine in the above embodiments replaces the traditional integral pressure plate with columnar contact points, reducing the pressure area on the fabric and avoiding fiber structure deformation caused by continuous large-area pressure. The gaps between the columns provide lateral deformation release space for high-elastic fabrics (such as spandex blends), preventing permanent indentations after stretching and rebound. Independent columns can respond to fabric surface undulations (such as seams and jacquard patterns), maintaining balanced pressure and avoiding sudden pressure increases caused by local bulges on rigid pressure plates. For highly sensitive materials such as thin silk and functional coated fabrics, discrete contact can also maximize the protection of surface smoothness and coating integrity. The columnar arrangement forms an air circulation channel, reducing frictional heat buildup between the fabric and the pressure plate during high-speed cutting and preventing thermoplastic fibers from melting and sticking together. X-axis slide rail displacement ensures that the cutting mechanism 3 moves accurately along the fabric width direction, adapting to different width requirements. Y-axis displacement allows the cutting head to cut laterally into any position on the fabric, breaking through the limitation of traditional fabric cutting machines that can only cut at the ends. The Z-axis lifting mechanism dynamically controls the cutting pressure, enabling flexible switching between "light touch cutting" and "heavy pressure penetration" to reduce the burr rate of the cut edges. The three-axis linkage capability allows the cutting mechanism 3 to execute non-linear trajectories (such as arcs and serrated lines), meeting the processing needs of special cut pieces (such as the curved hem of clothing and irregularly shaped parts of composite materials).
