Description

Technical Field

[0001] This invention relates to the field of garment cutting equipment technology, and in particular to a garment cutting equipment and its operator authentication system. Background Technology

[0002] Garment cutting equipment is the core processing machinery in garment production. It is used to precisely cut fabric into garment pieces according to a preset shape. Garment cutting equipment includes lateral cutting work through a fabric support mechanism and a fabric cutting machine head, and is used solely for dividing garments.

[0003] Commonly used equipment for horizontal cutting of clothing, it employs a rigid fabric support frame in conjunction with a unidirectional linear guide cutting mechanism. The fabric maintains tension only through gravity stretching at both ends. When processing elastic fabrics, this can cause the cutting path to deviate, thus affecting the cutting effect.

[0004] CN213596679U discloses a shearing platform for garment production. One end of the garment is positioned using a pressure strip, while the other end rotates via a pressure roller. The friction between the pressure roller and the garment straightens the fabric, preventing wrinkles from affecting the cutting dimensions. This shearing platform uses the pressure roller to compact the fabric, thereby reducing the impact on cutting. However, during the compaction process, for elastic fabrics, friction can still cause stretching, thus affecting the cutting effect.

[0005] CN114197195A discloses a precision cutting device for textile production, including a cutting table, a first drive component, and a second drive component. The second drive component drives a rotating component and a transmission assembly to rotate. The transmission assembly drives a lifting frame to move downwards via a rack and pinion 2. The lifting frame 1 drives a swinging component to rotate, and the swinging component drives the second lifting frame to move upwards, causing an elastic component 1 to generate a rebound force. The elastic component 1 uses this rebound force to fix the fabric with a pressing component. The cutting scissors achieve precise fabric cutting by cooperating with the pressing component to fix the fabric. In this case, the pressing component first presses down on the fabric, and then the cutting scissors move downwards to contact the fabric, cutting the fabric by driving the cutting scissors to move.

[0006] Meanwhile, the existing exposed cutting head and drive mechanism are directly external, posing a safety hazard. Furthermore, the entire operation of the equipment is controlled by a switch, which can cause problems when non-professional operators use the equipment.

[0007] CN112663317B discloses a fabric cutting device for garment manufacturing. The components and cutting structure of this device are exposed to the outside, which can easily lead to safety hazards. Moreover, non-professional operators can also operate the device. Therefore, it is necessary to design an operator identity authentication system for the cutting device to facilitate identity recognition before operation and avoid misoperation. Summary of the Invention

[0008] The technical problem to be solved by the present invention is: in order to overcome the problems existing in the prior art, when the transverse cutting equipment adopts a rigid fabric support frame and a unidirectional linear guide rail structure, it relies on gravity to stretch the fabric, which causes the elastic fabric to deviate during cutting, making it difficult to maintain flatness and tension, resulting in poor cutting accuracy and stability, as well as the problem of equipment misoperation, the present invention provides a garment cutting equipment and its operator identity authentication system.

[0009] The technical solution adopted by this invention to solve its technical problem is as follows: a garment cutting device, including a garment processing table, a fabric supporting device, and a cutting assembly; the fabric supporting device is disposed on the upper surface of the worktable of the garment processing table; the cutting assembly includes a cutting mechanism, a combination mechanism, and a fabric pressing mechanism; a cutting groove is formed through the worktable; the cutting combination box is disposed on the lower end surface of the cutting groove on the worktable; the fabric pressing mechanism is disposed on the upper end surface of the worktable; the cutting mechanism includes cutting scissors and a driving mechanism; the cutting scissors are correspondingly disposed at the position of the cutting groove and are driven by the driving mechanism to rise and fall relative to the cutting groove; the combination mechanism is connected between the cutting scissors and the fabric pressing mechanism; when the cutting scissors rise, they drive the fabric pressing mechanism to press down and position the fabric against the upper surface of the worktable and spread the fabric outward.

[0010] In the above scheme, the cutting mechanism and the pressing mechanism are linked. When the cutting scissors rise, the cutting mechanism, the combination mechanism and the pressing mechanism work together to drive the pressing mechanism to press down, so that the pressing and cutting operations can be realized simultaneously. This helps to ensure that the fabric remains taut during the cutting process, and the cutting is lag-free, ensuring the accuracy and consistency of the cutting process.

[0011] Furthermore, the cutting mechanism also includes a first adjusting plate, a second adjusting plate, and support rods. The second adjusting plate is horizontally positioned above the first adjusting plate, and the second adjusting plate and the first adjusting plate are supported and fixed together by the support rods. The support rods are symmetrically arranged on both sides of the cutting blades. A through hole is provided on the worktable corresponding to the position of the support rod for the support rod to extend through. The combined mechanism is located at the top of the support rod. A second support spring is arranged around the outer circumference of the support rod extending from the worktable. The lower end of the second support spring is elastically connected to the cutting mechanism, and the upper end is elastically connected to the combined mechanism. A set of fabric pressing mechanisms is correspondingly provided on the combined mechanism on the same side. The cutting blades are fixed to the second adjusting plate. The driving mechanism drives the first adjusting plate to rise, and the second adjusting plate and the cutting blades rise along with the first adjusting plate. Through the arrangement of the cutting mechanism, the driving mechanism, in cooperation with the first and second adjusting plates, drives the cutting blades to move in the height direction.

[0012] Furthermore, the drive mechanism includes a drive motor and an adjusting shaft. The adjusting shaft is fixed to the output end of the drive motor. An arc-shaped protrusion protrudes from the outer circumference of the adjusting shaft. When the output end of the drive motor rotates, the arc-shaped protrusion contacts the lower end face of the second adjusting plate and intermittently drives the second adjusting plate to move upward. The design of the arc-shaped protrusion creates a cam structure when the adjusting shaft rotates, thus intermittently driving the second adjusting plate to move during rotation.

[0013] Furthermore, a pressure block is fixed on the first adjusting plate, and a combined pressure groove is formed on the outer circumferential surface of the adjusting shaft. The outer surface of the pressure block is matched with the groove shape of the combined pressure groove. The radial section of the adjusting shaft corresponding to the combined pressure groove has a large fan-shaped structure, and the central corner of the fan-shaped structure is set with an arc-shaped chamfer. The pressure block is a triangular structure adapted to the central corner of the large fan-shaped structure, and the apex of the triangular structure of the pressure block is also set with an arc-shaped chamfer. The arc-shaped protrusion is located at the midpoint of the arc of the large fan-shaped structure along the circumference of the adjusting shaft. In the cooperation between the adjusting shaft and the first and second adjusting plates, the groove fit ensures that the pressure block and the adjusting shaft can maintain a limited position when the adjusting shaft rotates, thus completing the position limitation of the adjusting shaft of the drive mechanism and the cutting mechanism. When rotating to the outer circumferential surface of the adjusting shaft, the pressure block is pressed down by the cooperation between the outer circumferential surface and the arc-shaped chamfer of the pressure block, completing the pressing operation of the first adjusting plate.

[0014] Furthermore, the cutting mechanism also includes a cutting assembly box, which is suspended below the worktable. The first adjusting plate, the second adjusting plate, and the support rod are all housed within the cutting assembly box, and the output end of the drive motor extends into the cutting assembly box. A sealing square groove is circumferentially formed on the top surface of the cutting assembly box, and a cover plate flush with the top surface of the cutting assembly box is installed within the sealing square groove. The cover plate has holes for the support rod to pass through, and a knife groove corresponding to the knife groove position on the worktable is also formed on the cover plate for the cutting scissors to pass through. The lower end of the second support spring is elastically connected to the cover plate, and the first support spring is elastically supported between the upper surface of the second adjusting plate and the lower surface of the cover plate. The first support spring provides elastic support between the cover plate and the second adjusting plate. The design of the cutting assembly box provides installation space for the various adjusting plates within the cutting mechanism and also provides a positioning and installation position for the drive motor. The knife groove design on the cover plate provides space for the cutting edge when the cutting scissors move upwards, and the second support spring provides elastic support between the cover plate and the assembly mechanism carrying the support rod.

[0015] Furthermore, the cutting scissors are symmetrically provided with support rods at both ends on the same side, and a combination mechanism is fixed to the top of each support rod by a thread. The combination mechanisms on the support rods on both sides of the cutting scissors are symmetrically arranged. The combination mechanism includes a combination fixing block and an inclined platform. The combination fixing block is threaded to the top of the support rod, and an inclined platform is fixed to the bottom of the inner surface of the combination fixing block. The upper surface of the inclined platform is an inclined surface pointing downward and outward relative to the cutting scissors. A storage cavity is opened on the inner surface of the combination fixing block. A pressure spring is fixed to the top wall of the storage cavity, and an adjustment block is fixed to the lower end of the pressure spring. A pressure rod is connected between the adjustment blocks on the same side of the cutting scissors. The fabric pressing mechanism includes a fabric pressing shaft, a fabric pressing roller, and connecting handles connected to both ends of the fabric pressing roller. A fabric pressing rod is connected between the combination fixing blocks on the same side of the cutting scissors. One end of the connecting handle is rotatably connected to the fabric pressing roller, and the other end is fixed to the fabric pressing shaft. An inclined platform supports the connecting handle below the corresponding mating position. The pressure roller not only automatically falls and presses down on the fabric under the action of gravity and inertia, but also incorporates a combined mechanism during the falling process. Through this combined mechanism, a downward spring provides a downward spring force to the pressure rod, limiting the lifting of the connecting handle in the height direction. By pressing down on the connecting handle with the pressure rod, the pressure roller can extend outward relative to the pressure rod, avoiding the problem of the pressure roller lifting excessively due to force. This allows the pressure roller connected to the connecting handle to effectively press down and extend outward to smooth the fabric, further achieving a flat operation during the fabric cutting process.

[0016] Preferably, to assist in positioning the fabric in the width direction before cutting, the fabric support device includes a fabric support rod and a pair of fabric support frames. The top of each fabric support frame has a combination docking groove, and each end of the fabric support rod is fixed with a connecting round rod. The outer diameter of the fabric support rod is larger than the outer diameter of the connecting round rod. The bottom of the combination docking groove has an installation groove, and a positioning roller is rotatably connected to the installation groove. The outer circumferential surface of the positioning roller engages with the connecting round rod. The docking groove is used to support and place the connecting round rod, while the design of the positioning roller effectively reduces the friction of the connecting round rod during placement, facilitating the unwinding and winding of the rolled fabric.

[0017] Furthermore, to accommodate cutting requirements of different fabric widths, the fabric support device includes a limiting rod. The outer circumference of the supporting rod has several adjusting through holes spaced apart along its axial direction. The inner wall of each adjusting through hole has an internal thread. A positioning stud is fixed to the outer circumference of the limiting rod. The outer circumference of the positioning stud has an external thread that mates with the internal thread of the adjusting through hole. After the positioning stud mates with the threaded adjustment through hole, one end of the limiting rod protrudes relative to the outer circumference of the supporting rod. In use, the corresponding adjusting through hole can be selected according to the fabric width, and the limiting rod with the positioning stud can be installed inside it. The limiting rod protruding from the supporting rod provides a width-direction limit for the fabric, further improving the fabric's stability.

[0018] An operation authentication system for garment cutting equipment is disclosed. The garment cutting equipment includes an operation panel on its processing table. The operation panel comprises an authentication module, a motor control module, and a security locking module. The authentication module performs either fingerprint verification or password verification. In fingerprint verification, the operation panel has a fingerprint sensor that captures a fingerprint image and transmits the signal to the authentication module, which then verifies the fingerprint and transmits a judgment signal to the motor control module. In password verification, the operation panel has numeric keys. The buttons adopt a non-continuous matrix anti-peeping layout, and the spacing between adjacent numeric keys is greater than 5mm. The authentication module receives the numeric combination input signal through the numeric keys and transmits the judgment signal to the motor control module. After successful authentication, the motor control module activates the single-press drive mechanism, and each press generates a command, which the drive motor receives and executes. The security locking module includes a mechanical no-operation timer and a locking button. The mechanical no-operation timer has a mechanical countdown gear set. After the countdown is completed, the gear set triggers a power cut-off signal to the drive motor. The locking button directly switches the power signal to the drive motor.

[0019] The control panel allows for the activation of the drive mechanism only after identity verification, effectively ensuring the legitimacy of the operator's identity and improving equipment safety. After the drive is activated, it can automatically power off after a long period of standby, or the power supply can be directly cut off via the locking button to avoid accidental activation, thus providing better reliability and safety.

[0020] Furthermore, in the single-press drive mechanism, the single-press drive mechanism generates a fixed pulse sequence of 200 pulses for each press, controls the drive motor to perform a 360°±0.5° rotation and then stops, and allows the operation interval time to be adjusted to more than 2 seconds.

[0021] The beneficial effect of this invention is that it provides a garment cutting device and its operator authentication system.

[0022] 1. Through a precisely designed drive motor and cutting assembly box, this equipment can effectively drive the combination mechanism and the fabric pressing mechanism to perform lifting and lowering movements, thereby uniformly pressing and flattening the fabric. This operation can significantly improve the fabric tension, ensuring that the fabric remains taut throughout the cutting process. Subsequently, the cutting scissors, through their design located inside the cutting assembly box, complete the rapid cutting in an efficient and precise manner, further ensuring the stability of the fabric and the accuracy of the cutting, while reducing the risks during operation.

[0023] 2. The coordinated action of the fabric support frame, fabric support rod, and fabric pressing mechanism ensures that the fabric is evenly tensioned and pressed before cutting, thereby effectively avoiding fabric deformation and uneven stretching, ensuring accuracy and consistency in the cutting process. The flexible adjustment function of the fabric support rod and positioning stud allows it to be precisely adjusted according to fabrics of different widths to adapt to different cutting needs.

[0024] 3. The adjustment components inside the cutting combination box cooperate with the rotating device on the drive motor so that during the rotation of the drive motor, the fabric pressing mechanism first presses and squeezes the fabric. Then, as the cutting scissors rise, the fabric pressing mechanism continues to apply pressure to the fabric to keep it flat. After the whole process is completed, the drive motor resets the equipment, realizing efficient cyclic operation and ensuring the stability and repeatability of each cut.

[0025] 4. The design of the combined mechanism and the pressing mechanism, especially during the pressing operation, the contact and squeezing between the pressing roller and the fabric, as well as the pressure applied by the pressing rod, effectively flatten the fabric and generate tension, improving the cutting effect. The pressing mechanism also has good ease of operation, which can easily complete the manual movement of the fabric after cutting, further optimizing the operation process and ensuring that the processing of the fabric after cutting is simpler and more efficient.

[0026] 5. The operation panel combined with the identity verification module ensures the legitimacy of the operator's identity and improves the security of the equipment. In addition, the safety lock module and the mechanical no-operation timer can effectively prevent misoperation and use by unauthorized personnel. Attached Figure Description

[0043] The invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner. Therefore, they only show the components relevant to the invention, and the orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be limiting, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0044] like Figures 1 to 13 The garment cutting device shown is an embodiment of the garment cutting device of the present invention.

[0045] The garment cutting equipment includes a garment processing table 1, support legs 2, fabric support frame 3, fabric support rod 4, drive motor 6, cutting combination box 7, and combination mechanism.

[0046] The garment processing table 1 has a work surface, with support legs 2 symmetrically and fixedly connected to the bottom surface of the work surface. Fabric support frames 3 are fixedly connected to the left and right sides of the upper surface of the garment processing table 1 in the width direction. Fabric support rods 4 are installed between the fabric support frames 3, and the fabric support rods 4 are located above the garment processing table 1. The axis of the fabric support rods 4 is typically in the width direction of the fabric.

[0047] A mounting frame 5 is fixedly connected to the center of the bottom surface of the garment processing table 1, and a drive motor 6 is embedded in the mounting frame 5. A cutting assembly box 7 is installed behind the drive motor 6. The output end of the drive motor 6 extends into the cutting assembly box 7, and the top of the cutting assembly box 7 is embedded and fixed to the garment processing table 1. A combination mechanism is installed above the cutting assembly box 7 and the garment processing table 1, and a fabric pressing mechanism 9 is rotatably installed between the combination mechanisms.

[0048] The top of the fabric support frame 3 is provided with a combination docking groove 31, and the inner wall of the top of the fabric support frame 3 is provided with an installation groove 32. A positioning roller 33 is installed inside the installation groove 32, and the top part of the positioning roller 33 is located inside the combination docking groove 31. The positioning roller 33 is connected to the fabric support frame 3 by rotation. The positioning roller 33 is symmetrically distributed on the fabric support frame 3. By adjusting the combination docking groove 31 and the installation groove 32, the fabric can be supported and stabilized, thereby improving the stability of the fabric during the rotating feeding process.

[0049] A connecting rod 42 is fixedly installed at the center of the end face of the support rod 4, and the connecting rod 42 passes through the combined docking groove 31. The outer surface of the connecting rod 42 is in contact with the outer surface of the positioning roller 33, and rolling friction is formed between the connecting rod 42 and the positioning roller 33.

[0050] The outer circumferential surface of the fabric support rod 4 is provided with equal-spaced adjustment through holes 41 along its axial direction. The inner wall of the adjustment through hole 41 is threaded and a positioning stud 43 is threadedly installed thereon. The height of the positioning stud 43 is less than the diameter of the fabric support rod 4, and a limit rod 44 is fixedly installed at the center of the end of the positioning stud 43. The height of the limit rod 44 plus the positioning stud 43 is greater than the diameter of the fabric support rod 4. When the positioning stud 43 is installed in conjunction with the adjustment through hole 41, the limit rod 44 protrudes relative to the outer circumferential surface of the fabric support rod 4, forming a limiting structure in the fabric width direction.

[0051] The above structure forms a fabric support device. The fabric support rod 4 is connected to the fabric support frame 3 by a rotating connection through the connecting round rod 42, the positioning roller 33 and the combined docking groove 31. By installing the positioning stud 43 and the limiting rod 44 on the adjustment through holes 41 at different positions at both ends of the fabric support rod 4 according to the width of the fabric, it can be flexibly adjusted according to the width of the fabric. At the same time, the fabric is smoothly rotated and fed through the combination of the connecting round rod 42 and the positioning roller 33 on the fabric support rod 4.

[0052] An adjusting shaft 61 is fixed to the output end of the drive motor 6. The outer circumferential surface of the adjusting shaft 61 has arc-shaped protrusions 62 and a combined pressure groove 63. The adjusting shaft 61 is embedded in the output end of the drive motor 6 and extends into the interior of the cutting assembly box 7. The combined pressure groove 63 is formed on the curved surface at the middle end of the adjusting shaft 61. Arc-shaped protrusions 62 are provided at both ends of the outer circumferential surface of the adjusting shaft 61 corresponding to the axial direction of the combined pressure groove 63. That is, in the axial direction of the adjusting shaft 61, the combined pressure groove 63 is located between the arc-shaped protrusions 62. The rotation of the adjusting shaft 61 drives the arc-shaped protrusions 62 and the combined pressure groove 63 to rotate synchronously. The combined pressure groove 63 cooperates with the pressure block 76 of the first adjusting plate 75 to achieve precise control during the cutting process.

[0053] A sealing square groove 71 is circumferentially formed on the top surface of the cutting assembly box 7. A cover plate 72 is installed inside the sealing square groove 71, and the top surface of the cover plate 72 is flush with the top surfaces of the cutting assembly box 7 and the garment processing table 1. A knife groove 73 is formed in the center of the cover plate 72. The cover plate 72 is fixedly connected to the cutting assembly box 7 by fastening bolts 74. The cutting assembly box 7 has a first adjusting plate 75 and a second adjusting plate 78 inside. The first adjusting plate 75 is located below the adjusting shaft 61, and the second adjusting plate 78 is located above the adjusting shaft 61. A pressure block 76 is installed on the top center of the first adjusting plate 75. When the radial section of the adjusting shaft 61 at the position corresponding to the combined pressure groove 63 is a large fan-shaped structure, the central corner of the fan-shaped structure is set with an arc chamfer. The pressure block 76 is a triangular structure adapted to the central corner of the large fan-shaped structure, and the apex of the triangular structure of the pressure block 76 is also set with an arc chamfer. The arc-shaped protrusion 62 is located at the midpoint of the arc of the large fan-shaped structure along the circumference of the adjusting shaft 61.

[0054] The rotation of the adjusting shaft 61 causes the pressure block 76 to be connected to the combined pressure groove 63 via a groove-shaped friction fit. When the pressure block 76 is located within the combined pressure groove 63, the arc-shaped protrusion 63 rotates and gradually approaches and contacts the second adjusting plate 78 above it, pushing the second adjusting plate 78 upwards and then moving away from it. As it moves away from the second adjusting plate 78, the outer circumferential surface of the adjusting shaft 61 engages with the pressure block 76 at a fixed point, pressing the pressure block 76 and the first adjusting plate 75 downwards.

[0055] Support rods 77 are threadedly fixed to the top surfaces of the four corners of the first adjusting plate 75, and the support rods 77 pass through the second adjusting plate 78 and the cover plate 72. The second adjusting plate 78 is located inside the cutting assembly box 7 and above the adjusting shaft 61. When the adjusting shaft 61 rotates, the second adjusting plate 78 comes into frictional contact with the arc-shaped protrusion 62 and moves up and down intermittently with the movement of the arc-shaped protrusion 62.

[0056] The top surface of the second adjusting plate 78 is provided with a cutting shear 79 and a first support spring 710, and the top tip of the cutting shear 79 is partially located inside the blade groove 73. The first support spring 710 is symmetrically distributed at equal intervals on both sides of the cutting shear 79 on the second adjusting plate 78. The bottom end of the first support spring 710 is spot-welded to the second adjusting plate 78, and the elastic support is provided between the second adjusting plate 78 and the cover plate 72.

[0057] A second support spring 711 is mounted around the top outer side of the support rod 77. The second support spring 711 is located between the cover plate 72 and the assembly mechanism, and its outer diameter is smaller than the length and width of the assembly mechanism, facilitating an elastic connection between the second support spring 711 and the assembly mechanism. Through the precise cooperation of the first adjusting plate 75 and the second adjusting plate 78, the cutting shears 79 can perform precise cutting at the appropriate position, while ensuring the stability and safety of the equipment during operation and preventing accidents.

[0058] The first adjusting plate 75 and the second adjusting plate 78 are slidably connected to the cutting assembly box 7, and the second adjusting plate 78 is slidably connected to the support rod 77. The first adjusting plate 75 and the pressure block 76 are integrated into a single structure. The second adjusting plate 78 is fixedly embedded to the cutting scissors 79, and the cutting scissors 79 are slidably connected to the cover plate 72 through the blade groove 73. This ensures that the cutting scissors 79 can move up and down smoothly during operation, avoiding obstruction and ensuring the stability and accuracy of the cutting process. At the same time, the operation of the first adjusting plate 75 and the second adjusting plate 78 can improve the stability during operation and prevent misalignment and shaking.

[0059] The assembly mechanism includes a fixed assembly block 8, an inclined platform 81, a pressure spring 83, an adjusting block 84, and a pressure rod 85. The fixed assembly block 8 is threadedly fixed to the top of the support rod 77. The inclined platform 81 is fixedly connected to the inner surface of the bottom end of the fixed assembly block. A receiving cavity 82 is formed on the inner surface of the top end of the fixed assembly block. The pressure spring 83 and the adjusting block 84 are installed inside the receiving cavity 82, with the adjusting block 84 located below the pressure spring 83. The upper end of the pressure spring 83 is fixed to the top wall of the receiving cavity 82, and the lower end is fixed to the adjusting block 84. A pressure rod 85 is installed between the adjusting blocks 84 on the same side as the cutting shears 79.

[0060] The fabric pressing mechanism includes a fabric pressing shaft 9, a fabric pressing roller body 92, and connecting handles 91 connected to both ends of the fabric pressing roller body. The fabric pressing shaft 9 is rotatably mounted between the combined fixing blocks 8 located on the same side as the cutting shears. The rotation of the fabric pressing mechanism is all centered on the axis of the fabric pressing shaft 9. One end of the connecting handle 91 is rotatably connected to the fabric pressing roller body 92, and the other end is fixed to the fabric pressing shaft 9. The connection method between the connecting handle 91 and the pressing shaft 9 is embedded and fixed, and the connecting handle 91 is symmetrically distributed on the pressing shaft 9. The connection method between the connecting handle 91 and the tilting table 81, the connecting handle 91 and the pressing rod 85 is contact connection. The connection method between the pressing rod 85 and the adjusting block 84 is embedded and fixed. The adjusting block 84 forms a telescopic structure with the combined fixing block 8 through the storage cavity 82 and the pressing spring 83. The combined mechanism and the pressing mechanism 9 provide flexible fabric adjustment and pressing functions. The pressing roller 92 squeezes the fabric, and at the same time, the pressing roller 92 rotates and unfolds outward to flatten the fabric and keep it in a straight state. The pressing roller 92 can maintain stable and accurate reset work through the connection of the connecting handle 91 with the tilting table 81 and the pressing rod 85, and can be repeatedly operated.

[0061] During the cutting operation, the drive motor 6 drives the adjusting shaft 61 to rotate. The combined pressure groove 63 of the adjusting shaft 61 cooperates with the pressure block 76 to limit the adjusting shaft 61 axially relative to the first adjusting plate 75. When the adjusting shaft 61 rotates, the arc-shaped protrusion 62 on the adjusting shaft 61 forms a cam structure, intermittently lifting the second adjusting plate 78, thereby realizing the up and down movement of the cutting shears 79 to achieve the cutting operation on the fabric above. During this lifting process, due to the arrangement of the first support spring 710 and the second support spring 711, as the second adjusting plate 78 rises, it compresses the first support spring 710 and stretches the second support spring 711, causing the combined mechanism to rise. The pressure rod 9 rises, and the pressure roller 92, due to inertia, briefly descends relative to the pressure rod 9. This results in the fabric being compressed during the cutting process of the cutting shears 79. After inertia, the pressure rod 9 carries the pressure roller 92 upwards, and the pressure roller 92 extends outwards relative to the pressure rod 9, further flattening and tautning the fabric. This achieves the operation of pressing and tautning the fabric using the pressure roller 92 during the cutting process. One rotation of the adjusting shaft 61 completes one cycle of the cutting shears 79 rising, the pressure roller 92 pressing and extending the fabric, the cutting shears 79 descending, and the pressure roller 92 releasing the fabric.

[0062] In this way, the fabric is effectively pressed, stretched, and cut. Compared to traditional cutting mechanisms, which only perform a positioning and stretching operation on the fabric before cutting, and which may still cause fabric positioning deviation and poor stability during the cutting process, the garment cutting equipment provided in this embodiment performs pressing and outward stretching and stretching actions on the fabric during each lifting and lowering operation of the cutting shears. This effectively maintains the flatness and tension of the fabric during the cutting process, resulting in high cutting accuracy and stability.

[0063] like Figure 1 and Figure 14 The illustrated identity authentication system for a garment cutting device is an embodiment of the operational identity authentication system of this invention. This embodiment, based on the aforementioned garment cutting device technology, includes an operation panel 10 embedded and fixedly installed on the front right side of the garment processing table 1.

[0064] The operation panel 10 includes an authentication module, a motor control module, and a security lock module. The authentication module performs either fingerprint fast verification or password verification. Fingerprint fast verification uses an oil-resistant capacitive sensor to acquire fingerprint images and extract five key topological feature points within the fingerprint core area. These five key topological feature points include two triangular areas and three ridge bifurcation points, and a dynamic matching template is generated. The sensor is embedded in the panel's sealing groove and its surface is covered with a hydrophobic and oleophobic coating. Password verification receives a 4-digit combination input. The password verification buttons adopt a non-continuous matrix anti-peeping layout, with adjacent spacing greater than 5mm. The motor control module... After successful verification, the single-press drive mechanism is activated, generating a fixed pulse sequence of 200 pulses with each press. This controls the drive motor 6 to rotate 360°±0.5° before stopping, and the operation interval can be adjusted to more than 2 seconds. The safety locking module includes a mechanical no-operation timer and a locking button. The mechanical no-operation timer triggers a lever to cut off the main power supply after 20 minutes of rest via a spring-loaded gear set. The locking button directly drives an electromagnetic relay to cut off the power supply to the drive motor 6. The fingerprint verification module and the password verification module work together to ensure that only authorized personnel can operate the device, improving the device's security and preventing unauthorized personnel from using the device.

[0065] The fingerprint recognition sensor is an oil-resistant capacitive sensor, which is mounted on the operation panel 10. The seam between the sensor and the operation panel 10 is filled with polyurethane waterproof adhesive. The signal line of the oil-resistant capacitive sensor is connected to the control board of the drive motor 6, ensuring that the fingerprint verification module can operate stably for a long time even in harsh environments. The waterproof adhesive also increases the durability of the fingerprint verification module.

[0066] The working principle of this embodiment: According to Figures 1 to 5First, the garment processing table 1 is placed stably by the support legs 2 to provide stable support for the whole. According to the width of the fabric, the positioning studs 43 and the limiting rods 44 are properly installed and fixed through the adjustment through holes 41 at different positions on the fabric support rods 4, so that the fabric is located between the upper limit rods 44 of the fabric support rods 4. Then, the fabric is brought into contact with the positioning rollers 33 in the combined docking groove 31 through the connecting round rods 42 on the fabric support rods 4 to achieve the support work. At the same time, the fabric support rods 4 rotate smoothly through the connecting round rods 42 and the positioning rollers 33 to feed the fabric. Then, one end of the fabric passes through the space between the garment processing table 1 and the pressing roller body 92.

[0067] according to Figure 1 , Figure 2 and Figure 14 Next, when using the device, the operator first needs to authenticate their identity through fingerprint verification or password input. The fingerprint recognition sensor is built into the operation panel 10. When the operator places their finger on the sensor, the sensor scans the fingerprint image in real time. The scanned fingerprint image is converted into digital information by a capacitive sensor and compared with the authorized fingerprint data stored in the device. If the comparison is successful, the identity verification is successful, the device will be unlocked, and the operator can proceed with subsequent operations. If fingerprint verification fails or the operator chooses to verify via password, the operator can enter a password using the numeric keypad on the operation panel 10. The entered password is compared with the password in the device system to verify its correctness. If the password is correct, the device will also be unlocked and operation can continue. Before the identity verification is successful, the security lock module will keep the device locked to prevent unauthorized personnel from operating the device. Only after the identity verification module has authenticated the device will the security lock module be unlocked, allowing the operator to control the device normally. The fingerprint recognition sensor is protected by waterproof adhesive to ensure that the fingerprint recognition module can still work stably when facing environmental factors such as oil and moisture. When the operator is working, a single press can drive the drive motor 6 to rotate one revolution to perform a cutting operation.

[0068] according to Figure 1 , Figure 2 , Figures 6 to 13During the rotation of the drive motor 6, the drive motor 6 drives the adjusting shaft 61 and the arc-shaped protrusion 62 to rotate within the cutting assembly box 7. As the adjusting shaft 61 rotates, the pressure block 76 is pressed and separates from the combined pressure groove 63, sliding out and allowing the pressure block 76 to adhere to the outer surface of the adjusting shaft 61, maintaining stability after pressing. The pressure block 76 drives the first adjusting plate 75 to descend within the cutting assembly box 7. The first adjusting plate 75 slides down via the support rod 77, which slides on the second adjusting plate 78 and the cover plate 72. Simultaneously, the support rod 77 drives the combination mechanism and the fabric pressing mechanism 9 to descend. The combination mechanism pushes the second support spring 711 to retract. The fabric pressing mechanism 9 drives the fabric pressing roller 92 to first press against the fabric. During the pressing process, the fabric pressing roller 92 rotates outward under pressure. The fabric pressing roller 92 rotates between the combination mechanism via the connecting handle 91 and the fabric pressing mechanism 9. The connecting handle 91 pushes the pressure rod 85 upward, and the pressure rod 85 drives the adjusting block 84 to slide in the storage cavity 82. The adjusting block 84 pushes the downward pressure spring 83 to contract, increasing the thrust on the connecting handle 91 and the pressure roller 92, maintaining stability and pressure during the unfolding process. The pressure roller 92 squeezes and stretches the fabric to maintain tension. When the adjusting shaft 61 drives the arc-shaped protrusion 62 to contact the second adjusting plate 78, it squeezes and pushes it. The second adjusting plate 78 rises smoothly in the cutting assembly box 7 through the support rod 77. The second adjusting plate 78 pushes the first support spring 710 to contract. At the same time, the second adjusting plate 78 drives the cutting scissors 79 to rise. The cutting scissors 79 slide out from the knife groove 73 and cut the taut fabric. According to the strength and toughness of the fabric, the matching cutting scissors 79 can be replaced. After the cutting is completed, the adjusting shaft 61 rotates to one revolution and then stops. Simultaneously, the arc-shaped protrusion 62 separates from the second adjusting plate 78, and the pressure block 76 slides back into the combined pressure groove 63. The first adjusting plate 75 and the second adjusting plate 78 are reset according to the above principle and the elastic force of the first support spring 710 and the second support spring 711. The pressure roller 92 separates from the fabric, and the tip of the cutting scissors 79 slides back to the knife groove 73 for storage. When the pressure roller 92 is not pressed, the pressure rod 85 is reset by the elastic force of the adjusting block 84 through the downward pressure spring 83. The pressure rod 85 pushes the connecting handle 91 to drive the pressure roller 92 to reset. The connecting handle 91 is limited by the tilting table 81 and resets to the initial position. After the whole is completely reset, the fabric cutting is finished, the cutting scissors 79 are stored, and the garment in the cutting area can be pulled to repeat the operation. The overall operation is simple and convenient.

[0069] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0070] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
