Description

Technical Field

[0001] The present invention relates to the technical field of garment cutting equipment, and particularly to a garment cutting equipment and its operation identity authentication system. Background Art

[0002] Garment cutting equipment is the core processing machinery in garment production, which is used to accurately cut fabric into garment pieces according to a preset shape. The garment cutting equipment includes horizontal cutting work through a fabric supporting mechanism and a cloth cutting machine head, and a single work for separating garments.

[0003] Common equipment for horizontal cutting of garments uses a rigid fabric support frame and a unidirectional linear guide cutting mechanism. The fabric only maintains tension through gravity stretching at both ends. When processing elastic fabric, the cutting path will shift, affecting the cutting effect.

[0004] CN213596679U discloses a cutting platform for garment production. One end of the garment is positioned by a pressing strip, and the other end rotates through a pressing roller. Under the action of friction between the pressing roller and the garment to be cut, the garment fabric is straightened to prevent the cutting size from being affected due to the folds of the garment. This cutting platform compacts the fabric with the pressing roller to reduce the impact of cutting. However, during the compaction operation, for elastic fabric, the friction will still stretch the fabric, affecting the cutting effect.

[0005] CN114197195A discloses a precise cutting equipment for textile production, including a cutting table, a driving member one and a driving member two. The driving member two drives the rotating member and the transmission component to rotate. The transmission component drives the lifting frame one to move downward through a rack two. The lifting frame one drives the swinging member to rotate, and the swinging member drives the lifting frame two to move upward, so that the elastic member one generates a rebound force. The elastic member one uses the rebound force to fix the fabric with the pressing member. The cutting scissors achieve the effect of precisely cutting the fabric by cooperating with the pressing member to fix the fabric. In this case, the pressing member first presses down the fabric, and then the cutting scissors move downward and abut against the fabric, and cut the fabric by driving the cutting scissors to move.

[0006] At the same time, the existing exposed cutting scissors head and the driving mechanism are directly external, posing a safety hazard. And the overall operation of the equipment is operated through a switch, resulting in problems when non-professional operators use the equipment.

[0007] CN112663317B discloses a fabric cutting equipment for garment manufacturing. The components and cutting structure of this device are exposed outside, which is prone to safety hazards, and non-professional operators can also operate this device. Therefore, it is necessary to design an operation identity authentication system for the cutting equipment 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 that in the process of fabric cutting, the horizontal cutting device adopts a rigid fabric support frame and a unidirectional linear guide rail structure, relying on gravity to stretch the fabric, resulting in cutting deviation of elastic fabric, it is difficult to maintain flatness and tension, the cutting accuracy and stability are poor, and there are problems of equipment misoperation. The present invention provides a clothing cutting device and its operation identity authentication system.

[0009] The technical solution adopted by the present invention to solve its technical problems is: a clothing cutting device, including a clothing processing table, a fabric support device and a cutting assembly; the fabric support device is arranged on the upper end face of the workbench of the clothing processing table; the cutting assembly includes a cutting mechanism, a combination mechanism and a fabric pressing mechanism. A knife groove is penetrated and opened on the workbench surface. The cutting combination box is arranged on the end face below the knife groove of the workbench surface, and the fabric pressing mechanism is arranged on the end face of the workbench surface above the knife groove; a cutting knife and a driving mechanism are arranged in the cutting mechanism. The cutting knife is correspondingly arranged at the position of the knife groove and is driven by the driving mechanism to rise and fall relative to the knife groove. The combination mechanism is connected between the cutting knife and the fabric pressing mechanism. When the cutting knife rises, it drives the fabric pressing mechanism to press down and positionally abut the fabric against the upper end face of the workbench surface and unfold the fabric.

[0010] In the above solution, the cutting mechanism and the fabric pressing mechanism are linked. When the cutting knife rises, the fabric pressing mechanism is synchronously driven to press down by the cooperation of the cutting mechanism, the combination mechanism and the fabric pressing mechanism, so that the pressing and shearing operations can be realized synchronously, which is beneficial to ensuring that the fabric remains in a straightened state during the cutting process, there is no lag in cutting, and the accuracy and consistency during the cutting process are ensured.

[0011] Further, the cutting mechanism further includes a first adjusting plate, a second adjusting plate and a support rod; the second adjusting plate is horizontally arranged above the first adjusting plate, and the second adjusting plate and the first adjusting plate are supported and fixed by the support rod. The support rods are symmetrically arranged on both sides of the cutting knife; through holes for the support rods to penetrate and extend are correspondingly opened on the workbench surface at the positions corresponding to the support rods. The combination mechanism is arranged on the top of the support rod. A second support spring is circumferentially arranged around the outer side of the support rod corresponding to the part extending out of the workbench surface. The lower end of the second support spring is elastically connected to the cutting mechanism, and the upper end is elastically connected to the combination mechanism. A set of fabric pressing mechanisms are correspondingly arranged on the combination mechanism on the same side; the cutting knife is fixed on the second adjusting plate; the driving mechanism drives the first adjusting plate to make a rising movement, and the second adjusting plate and the cutting knife rise with the rise of the first adjusting plate. Through the setting of the cutting mechanism, the driving mechanism is used in cooperation with the first adjusting plate and the second adjusting plate to drive the cutting knife to move in the height direction.

[0012] Further, the driving mechanism includes a driving motor and an adjusting rotating shaft. The adjusting rotating shaft is fixed to the output end of the driving motor. An arc-shaped convex block protrudes from the outer peripheral surface of the adjusting rotating shaft. When the arc-shaped convex block rotates at the output end of the driving motor, it contacts the lower end surface of the second adjusting plate and intermittently drives the second adjusting plate to move upward. Through the design of the arc-shaped convex block, when the adjusting rotating shaft rotates, a cam structure is formed, thereby intermittently driving the second adjusting plate to act during rotation.

[0013] Further, a pressing block is fixed on the first adjusting plate. A combined pressing groove is formed on the outer peripheral surface of the adjusting rotating shaft. The outer surface of the pressing block is in limit fit with the groove shape of the combined pressing groove. The groove shape of the radial cross-section of the adjusting rotating shaft corresponding to the combined pressing groove is a large sector structure, and an arc-shaped chamfer is provided at the central angle of the sector structure. The pressing block is a triangular structure adapted to the central angle of the large sector structure, and the vertex of the triangular structure of the pressing block is also provided with an arc-shaped chamfer. The arc-shaped convex block is located at the midpoint of the arc of the large sector structure along the circumferential direction of the adjusting rotating shaft. During the cooperation between the adjusting rotating shaft and the first and second adjusting plates, through the groove shape cooperation, when the adjusting rotating shaft rotates, the pressing block and the adjusting rotating shaft can maintain a limit, that is, the position limitation between the adjusting rotating shaft of the driving mechanism and the cutting mechanism is completed. When rotating to the outer peripheral surface of the adjusting rotating shaft, the outer peripheral surface and the arc-shaped chamfer of the pressing block are used to press down the pressing block to complete the pressing operation of the first adjusting plate.

[0014] Further, the cutting mechanism further includes a cutting combination box, which is suspended under the workbench surface. The first adjusting plate, the second adjusting plate, and the support rod are all arranged in the cutting combination box. The output end of the driving motor extends into the cutting combination box. A sealing square groove is circumferentially formed on the top surface of the cutting combination box. A cover plate flush with the top surface of the cutting combination box is fitted and installed in the sealing square groove. The cover plate is provided with a hole for the support rod to pass through. A knife groove for the cutting knife to pass through is also formed on the cover plate corresponding to the knife groove position of the workbench surface. The lower end of the second support spring is elastically connected to the cover plate. A first support spring is elastically supported between the upper end surface of the second adjusting plate and the lower end 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 combination box provides an installation space for each adjusting plate in the cutting mechanism on the one hand, and also provides a positioning installation position for the driving motor on the other hand. The cover plate provides space for the cutting knife edge when the cutting knife moves upward through the design of the knife groove. The setting of the second support spring provides elastic support between the cover plate and the combined mechanism carrying the support rod.

[0015] Furthermore, support rods are symmetrically arranged at both ends in the same side direction of the cutting scissors. A combination mechanism is fixed to the top of each support rod by means of threads, and 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 table. The combination fixing block is fixed to the top of the support rod by threads. The bottom end of the inner surface of the combination fixing block is fixed with an inclined table. The upper surface of the inclined table is an inclined surface that is obliquely pointed downward and outward relative to the cutting scissors. A storage cavity is formed on the inner surface of the combination fixing block. A downward pressure spring is fixed to the top cavity wall of the storage cavity, and an adjustment square block is fixed to the lower end of the downward pressure spring. A pressure rod is connected between the adjustment square blocks on the same side of the cutting scissors; the cloth pressing mechanism includes a cloth pressing shaft, a cloth pressing roller body, and connection handles connected to both ends of the cloth pressing roller body. A cloth pressing rod is connected between the combination fixing blocks on the same side of the cutting scissors. One end of the connection handle is rotatably connected to the cloth pressing roller body, and the other end is fixed to the cloth pressing shaft. And there is an inclined table supporting below the corresponding matching position of the connection handle. The cloth pressing roller body can not only automatically fall and press the fabric under the action of gravity and inertia, but also cooperate with the setting of the combination mechanism during the falling process. Through the setting of the combination mechanism, the downward spring force of the downward pressure spring is provided for the pressure rod to limit the upward lift of the connection handle in the height direction. The pressure rod presses down the connection handle to realize the outward expansion operation of the cloth pressing roller body relative to the cloth pressing rod, avoiding the problem that the cloth pressing roller body is forced to lift excessively upward. Thus, the cloth pressing roller bodies connected between the connection handles can effectively press down and expand to flatten the fabric, further realizing the flattening operation during the fabric cutting process.

[0016] Preferably, in order to assist in positioning the fabric in the width direction before cutting, the cloth supporting device includes a cloth supporting rod and a pair of cloth supporting frames. A combined docking groove is formed at the top of the cloth supporting frame. Connecting round rods are respectively fixed to both ends of the cloth supporting rod, and the outer diameter of the cloth supporting rod is larger than that of the connecting round rod; an installation groove is formed at the bottom of the combined docking groove, and a positioning roller is rotatably connected to the installation groove. The outer peripheral surface of the positioning roller is in frictional cooperation with the connecting round rod. The docking groove is used to cooperate with and support the placement of the connecting round rod, and the design of the positioning roller effectively reduces the frictional force when the connecting round rod is placed, facilitating the winding and unwinding operation of the rolled fabric.

[0017] Further, in order to adapt to the cutting requirements of different widths, the cloth supporting device includes a limiting rod. A plurality of adjusting through holes are spaced along the axial direction on the outer peripheral surface of the cloth supporting rod. The inner wall of the adjusting through hole has an internal thread. A positioning stud is fixed on the outer periphery of the limiting rod. The outer peripheral surface of the positioning stud has an external thread that matches the internal thread of the adjusting through hole. After the limiting rod is threadedly engaged with the adjusting through hole by the positioning stud, one end portion protrudes relative to the outer peripheral surface of the cloth supporting rod. During use, according to the width of the fabric, the corresponding adjusting through hole can be selected, and the limiting rod with a positioning stud is assembled therein. The limiting rod protruding from the cloth supporting rod provides limitation in the width direction of the fabric, further improving the stability of the fabric.

[0018] An operation identity authentication system for a clothing cutting device uses the above-mentioned clothing cutting device. An operation panel is provided on the clothing processing table of the clothing cutting device. The operation panel includes an identity verification module, a motor control module, and a safety locking module. The identity verification module performs any one of the authentication methods of fingerprint quick verification or password verification. In fingerprint quick verification, a fingerprint recognition sensor is provided on the operation panel. The fingerprint recognition sensor collects a fingerprint image and transmits a signal to the identity verification module. The identity verification module verifies and transmits a judgment signal to the motor control module. In password verification, numeric keys are provided on the operation panel. The numeric keys adopt a non-continuous matrix anti-peeping layout, and the distance between adjacent numeric keys is greater than 5 mm. The identity verification module receives a numeric combination input signal through the numeric keys and transmits a judgment signal to the motor control module. After the verification is passed, the motor control module activates a single-press driving mechanism, and each press generates a command for the driving motor to receive and execute the command. The safety locking module includes a mechanical non-operation timer and a locking button. The mechanical non-operation timer has a mechanical countdown spring gear set. After the spring gear set counts down, it triggers to cut off the power signal of the driving motor. The locking button directly switches the power signal of the driving motor.

[0019] Through the setting of the operation panel, after the identity is verified, the driving mechanism can be driven, which can effectively ensure the legality of the operator's identity and improve the safety of the device. After the driving is executed, the power can be automatically cut off after a long standby, or the power supply can be directly cut off through the locking button to avoid accidental touch, with better reliability and safety.

[0020] Further, in the single-press driving mechanism, the single-press driving mechanism generates 200 fixed pulse sequences for each press, controls the driving motor to rotate 360° ± 0.5° and then stop, and allows the operation interval time to be adjusted to be more than 2 seconds.

[0021] The beneficial effects of the present invention are as follows. The present invention provides a clothing cutting device and its operation identity authentication system:

[0022] 1. Through the precisely designed drive motor and cutting combination box, the device can effectively drive the combination mechanism and the cloth pressing mechanism to perform lifting movements, thereby uniformly pressing down and flattening the fabric. This operation can significantly increase the tension of the fabric, ensuring that the fabric always remains straight during the cutting process. Subsequently, the cutting scissors, through their design inside the cutting combination box, complete rapid cutting in an efficient and precise manner, further ensuring the stability of the fabric and the accuracy of cutting, while reducing the risks during the operation process.

[0023] 2. The coordinated action of the cloth support frame, cloth support rods, and cloth pressing mechanism ensures the uniform tensioning and pressing of the fabric before cutting, thereby effectively avoiding fabric deformation and uneven stretching, and ensuring the accuracy and consistency during the cutting process. The flexible adjustment function of the cloth support rods and positioning studs enables them to be precisely adjusted according to fabrics of different widths to meet different cutting requirements;

[0024] 3. The adjustment components inside the cutting combination box cooperate with the rotating device on the drive motor, such that during one rotation of the drive motor, the cloth pressing mechanism first performs a pressing and squeezing operation on the fabric. Then, during the upward movement of the cutting scissors, the cloth pressing mechanism continues to apply a pressing force on the fabric to keep the fabric flat. After the entire process is completed, the drive motor resets the device, realizing an efficient cyclic operation and ensuring the stability and repeatability of each cutting;

[0025] 4. The design of the combination mechanism and the cloth pressing mechanism, especially during the downward pressing operation, the contact and extrusion between the cloth pressing roller body and the fabric, as well as the pressure exerted by the pressing rod, effectively flatten the fabric and generate tension, improving the cutting effect. The cloth pressing mechanism also has good operational convenience and can conveniently complete the manual movement of the fabric after cutting, further optimizing the operation process and ensuring that the handling of the fabric after cutting is more simple and efficient;

[0026] 5. By combining the operation panel with the identity authentication module, the legitimacy of the operator's identity is guaranteed, improving the safety of the device. In addition, the safety locking module and the mechanical no-operation timer can effectively prevent misoperations and unauthorized use. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0043] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner. Therefore, they only show the components related to the present invention. Directions and references (such as up, down, left, right, etc.) can only be used to assist in the description of the features in the drawings. Therefore, the following specific implementation mode is not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalent forms.

[0044] As Figures 1 to 13 shown, a kind of clothing cutting device is an embodiment of the clothing cutting device in the present invention.

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

[0046] The clothing processing table 1 has a workbench surface. Support legs 2 are symmetrically and fixedly connected to the bottom surface of the workbench surface. And on the left and right sides in the width direction of the upper end surface of the clothing processing table 1, a cloth support frame 3 is respectively fixedly connected. A cloth support rod 4 is installed between the cloth support frames 3, and the cloth support rod 4 is located above the clothing processing table 1. The axial direction of the cloth support rod 4 is usually the width direction of the fabric.

[0047] The bottom center of the clothing processing table 1 is fixedly connected with a mounting frame 5, and a drive motor 6 is inlaid and installed on the mounting frame 5. A cutting combination box 7 is installed behind the drive motor 6. The output end of the drive motor 6 extends into the cutting combination box 7. And the top end of the cutting combination box 7 is inlaid and fixed with the clothing processing table 1. A combination mechanism is installed above the cutting combination box 7 and the clothing processing table 1, and a cloth pressing mechanism 9 is rotatably installed between the combination mechanisms.

[0048] A combined docking groove 31 is provided at the top of the cloth support rack 3, and an installation groove 32 is provided on the inner wall of the top of the cloth support rack 3. A positioning roller 33 is installed inside the installation groove 32, and the top of the positioning roller 33 is partially located inside the combined docking groove 31. The positioning roller 33 is connected to the cloth support rack 3 in a rotating manner, and the positioning rollers 33 are symmetrically distributed on the cloth support rack 3. By adjusting the combined docking groove 31 and the installation groove 32, the fabric support can be adjusted to be stable, thereby improving the stability of the fabric during the rotating discharge process.

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

[0050] The outer circumference of the cloth-stretching rod 4 is provided with adjustment holes 41 at equal intervals along its axial direction. The inner wall of the adjustment hole 41 has threads and a positioning stud 43 is threadedly installed. The height of the positioning stud 43 is less than the diameter of the cloth-stretching rod 4, and a limiting rod 44 is fixedly installed at the end center of the positioning stud 43, and the height of the limiting rod 44 plus the positioning stud 43 is greater than the diameter of the cloth-stretching rod 4. When the positioning stud 43 is installed in conjunction with the adjustment hole 41, the limiting rod 44 is protruded relative to the outer circumference of the cloth-stretching rod 4 to form a limiting structure in the width direction of the fabric.

[0051] The above structure forms a cloth-supporting device, in which the cloth-supporting rod 4 is connected to the cloth-supporting frame 3 in a rotational manner by means of a connecting round rod 42, a positioning roller 33 and a combined docking groove 31. By installing the positioning studs 43 and the limiting rods 44 on the adjustment holes 41 at different positions at both ends of the cloth-supporting 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 discharged through the combination of the connecting round rod 42 and the positioning roller 33 on the cloth-supporting rod 4.

[0052] The output end of the driving motor 6 is fixed with an adjusting shaft 61, and the outer peripheral surface of the adjusting shaft 61 has an arc-shaped protrusion 62, and the outer peripheral surface of the adjusting shaft 61 is also provided with a combination pressing groove 63. The output end of the driving motor 6 is inlaid with the adjusting shaft 61, and the adjusting shaft 61 extends into the interior of the cutting combination box 7.

The arc-shaped protrusion 62 and the combination pressing groove 63 are driven to rotate synchronously by the rotation of the adjusting shaft 61, and the combination pressing groove 63 cooperates with the pressing block 76 of the first adjusting plate 75 to realize precise control during the cutting process.

[0053] The top surface of the cutting combination box 7 is circumferentially provided with a sealing square groove 71. A cover plate 72 is fitted and installed in the sealing square groove 71, and the top surface of the cover plate 72 is flush with the top surfaces of the cutting combination box 7 and the garment processing table 1. A knife groove 73 is provided at the center of the cover plate 72. The cover plate 72 is fixedly connected to the cutting combination box 7 through fastening bolts 74. Inside the cutting combination box 7, there are a first adjusting plate 75 and a second adjusting plate 78. The first adjusting plate 75 is located below the adjusting rotating shaft 61, and the second adjusting plate 78 is located above the adjusting rotating shaft 61. A pressing block 76 is installed on the top surface at the center of the first adjusting plate 75. When the groove shape of the radial cross-section of the adjusting rotating shaft 61 at the position corresponding to the combined pressing groove 63 is a large sector structure, the central angle of the sector structure is provided with an arc chamfer. The pressing block 76 is a triangular structure adapted to the central angle of the large sector structure, and the vertex of the triangular structure of the pressing block 76 is also provided with an arc chamfer. The arc-shaped convex block 62 is located at the midpoint of the arc of the large sector structure along the circumferential direction of the adjusting rotating shaft 61.

[0054] When the adjusting rotating shaft 61 rotates, the connection between the pressing block 76 and the combined pressing groove 63 is a friction fit with opposite groove shapes. When the pressing block 76 is located in the combined pressing groove 63, the arc-shaped convex block 63 rotates and gradually approaches and contacts the second adjusting plate 78 above, pushing the second adjusting plate 78 upward, and then moving away from the second adjusting plate 78. When moving away from the second adjusting plate 78, the outer peripheral surface of the adjusting rotating shaft 61 is in friction fit with the fixed point of the pressing block 76, pressing down the pressing block 76 and the first adjusting plate 75.

[0055] Support rods 77 are fixedly installed on the top surfaces at the four corners of the first adjusting plate 75 by threads, and the support rods 77 penetrate through the second adjusting plate 78 and the cover plate 72. The second adjusting plate 78 is located inside the cutting combination box 7 and above the adjusting rotating shaft 61. When the adjusting rotating shaft 61 rotates, the second adjusting plate 78 is in frictional contact with the arc-shaped convex block 62 and undergoes intermittent up and down movement along with the movement of the arc-shaped convex block 62.

[0056] A cutting knife 79 and a first support spring 710 are arranged on the top surface of the second adjusting plate 78, and the top end of the cutting knife 79 is partially located inside the knife groove 73. The first support springs 710 are symmetrically distributed on both sides of the cutting knife 79 at equal intervals on the second adjusting plate 78. The bottom ends of the first support springs 710 are spot-welded and fixed to the second adjusting plate 78, and are elastically supported between the second adjusting plate 78 and the cover plate 72.

[0057] A second support spring 711 is installed around the outer side of the top of the support rod 77, and the second support spring 711 is located between the cover plate 72 and the combined mechanism. Moreover, the outer diameter of the second support spring 711 is smaller than the length and width of the combined mechanism, facilitating the elastic connection and cooperation between the second support spring 711 and the combined mechanism. Through the precise cooperation of the first adjustment plate 75 and the second adjustment plate 78, it is ensured that the cutting knife 79 can perform precise cutting at a suitable position, while ensuring the stability and safety during the operation of the device and avoiding accidents.

[0058] The first adjustment plate 75 and the second adjustment plate 78 are connected to the cutting combination box 7 in a sliding connection manner, and the second adjustment plate 78 is connected to the support rod 77 in a sliding connection manner. The first adjustment plate 75 and the pressing block 76 are integrally structured. The second adjustment plate 78 is fixedly connected to the cutting knife 79 in an embedded manner, and the cutting knife 79 is connected to the cover plate 72 through a knife groove 73 in a sliding connection manner, ensuring that the cutting knife 79 can move up and down smoothly during the working process, avoiding obstruction, and ensuring the smoothness and accuracy of the cutting process. At the same time, the operation of the first adjustment plate 75 and the second adjustment plate 78 can improve the stability during the working process and avoid dislocation and shaking.

[0059] The combined mechanism includes a combined fixed block 8, an inclined table 81, a downward pressure spring 83, an adjustment square block 84, and a pressing rod 85. The combined fixed block 8 is fixedly installed on the top of the support rod 77 by threading. The inner surface of the bottom end of the combined fixed block is fixedly connected with the inclined table 81. The inner surface of the top end of the combined fixed block is provided with a storage cavity 82. The downward pressure spring 83 and the adjustment square block 84 are installed inside the storage cavity 82, and the adjustment square block 84 is located below the downward pressure spring 83. The upper end of the downward pressure spring 83 is fixed to the top cavity wall of the storage cavity 82, and the lower end is fixed to the adjustment square block 84. A pressing rod 85 is installed between the adjustment square blocks 84 on the same side as the cutting knife 79.

[0060] The cloth pressing mechanism comprises a cloth pressing shaft 9, a cloth pressing roller body 92 and a connecting handle 91 connected to both ends of the cloth pressing roller body. The cloth pressing shaft 9 is rotatably arranged between the combined fixing blocks 8 on the same side of the cutting knife. The cloth pressing mechanism rotates with the axis of the cloth pressing shaft 9 as the rotation axis. One end of the connecting handle 91 is rotatably connected to the cloth pressing roller body 92, and the other end is fixed to the cloth pressing shaft 9. The connection mode of the connecting handle 91 and the cloth pressing shaft 9 is inlay fixing, and the connecting handle 91 is symmetrically distributed on the cloth pressing shaft 9. The connection mode of the connecting handle 91 and the tilting platform 81, the connecting handle 91 and the pressing rod 85 is contact connection, and the pressing rod 85 and the adjusting block 84 are inlay fixing. The adjusting block 84 forms a telescopic structure with the combined fixing block 8 through the storage cavity 82 and the downward pressure spring 83. The combined mechanism and the cloth pressing mechanism 9 provide flexible fabric adjustment and pressing functions. The cloth pressing roller body 92 squeezes the fabric, and at the same time, the cloth pressing roller body 92 rotates outward to flatten the fabric and keep it straight. The cloth pressing roller body 92 can maintain stable and precise reset work through the connection of the connecting handle 91 with the tilting platform 81 and the pressing rod 85, and can operate repeatedly.

[0061] When cutting, the driving motor 6 drives the adjusting shaft 61 to rotate. The combined pressing groove 63 of the adjusting shaft 61 cooperates with the pressing block 76 to limit the adjusting shaft 61 relative to the first adjusting plate 75 in the axial direction. When the adjusting shaft 61 rotates, the arc-shaped protrusion 62 on the adjusting shaft 61 forms a cam structure, which intermittently lifts the second adjusting plate 78, thereby realizing the up and down movement of the cutting knife 79, and realizing the cutting operation of the upper fabric. During this lifting process, due to the setting of the first supporting spring 710 and the second supporting spring 711, the second adjusting plate 78 is raised, squeezing the first supporting spring 710, stretching the second supporting spring 711, the combined mechanism is raised, the cloth pressing rod 9 is raised, and the cloth pressing roller 92 is briefly lowered relative to the cloth pressing rod 9 due to inertia, thereby squeezing the fabric when the cutting knife 79 is raised for cutting. After inertia, the cloth pressing rod 9 brings the cloth pressing roller 92 upward, and the cloth pressing roller 92 is extended relative to the cloth pressing rod 9, further flattening the fabric and keeping it straight. The cutting knife 79 uses the cloth pressing roller 92 to press and extend the fabric during the cutting process. The adjusting shaft 61 rotates one circle to complete the operation of the cutting knife 79 rising, the cloth pressing roller 92 pressing and extending the fabric, the cutting knife 79 descending, and the cloth pressing roller 92 releasing the fabric.

[0062] Compared with the traditional cutting mechanism, which only performs one positioning and straightening operation on the fabric before cutting, and may still cause the fabric positioning deviation and poor stability during the cutting process, the clothing cutting device provided by this embodiment has the action of pressing and stretching the fabric each time the cutting blade 79 is raised and lowered, which can effectively keep the fabric flat and taut during the cutting process, and has high cutting accuracy and stability.

[0063] As Figure 1 and Figure 14 shown, an identity authentication system for a clothing cutting device is an embodiment of operating the identity authentication system in the present invention. Based on the technology of the above-mentioned clothing cutting device, an operation panel 10 is fixedly installed by embedding at the right front end of the clothing processing table 1.

[0064] The operation panel 10 includes an identity verification module, a motor control module, and a safety locking module. The identity verification module performs either fingerprint quick verification or password verification. For fingerprint quick verification, a fingerprint image is collected by an anti-oil and water capacitance sensor, five topological key feature points within the core area of the fingerprint are extracted. The five topological key 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 sealing groove and its surface is covered with a hydrophobic and oleophobic coating. For password verification, a 4-digit number combination input is received. The keys for password verification adopt a non-continuous matrix anti-peeping layout, and the adjacent spacing is greater than 5 mm. The motor control module activates a single-press drive mechanism after successful verification, and each press generates 200 fixed pulse sequences, controlling the drive motor 6 to rotate 360° ± 0.5° and then stop, and allowing the operation interval time to 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 static state through a spring 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 security of the device and preventing unauthorized use of the device.

[0065] The fingerprint recognition sensor uses an anti-oil and water capacitance sensor. This sensor is installed on the operation panel 10, and the joint between the sensor and the operation panel 10 is filled with polyurethane waterproof glue. Moreover, the signal line of the anti-oil and water capacitance sensor is connected to the control board of the drive motor 6, ensuring that the fingerprint verification module can still operate stably for a long time in a harsh environment. Through the filling of the waterproof glue, the durability of the fingerprint verification module is increased.

[0066] The working principle of this embodiment: According to Figures 1 to 5, first, the clothing processing table 1 is stably placed through the support legs 2 to provide stable support for the whole. According to the width dimension of the fabric, the positioning studs 43 and the limiting rods 44 are fixedly installed appropriately through the adjustment through holes 41 at different positions on the cloth support rod 4, so that the fabric is located between the limiting rods 44 on the cloth support rod 4. Then, the fabric is attached to the positioning rollers 33 in the combined docking groove 31 through the connecting round rods 42 on the cloth support rod 4 to achieve the support work. At the same time, the subsequent cloth support rod 4 rotates smoothly through the connecting round rods 42 and the positioning rollers 33 to carry out the fabric feeding work. Then, one end of the fabric is passed through the space between the clothing processing table 1 and the cloth pressing roller body 92.

[0067] According to Figure 1 , Figure 2 and Figure 14 , then when the operator uses the equipment, first, identity authentication needs to be carried out through fingerprint verification or password input. The fingerprint recognition sensor is built into the operation panel 10. The operator places the finger on the sensor, and the sensor will scan the fingerprint image in real time. The scanned fingerprint image will be converted into digital information through the capacitive sensor and compared with the authorized fingerprint data stored in the equipment. If the comparison is successful, it means that the identity authentication is passed, and the equipment will unlock and allow the operator to perform subsequent operations. When the fingerprint verification fails or the operator chooses to verify through the password, the operator can input the password through the numeric keypad on the operation panel 10. The input password is compared with the password in the equipment system to verify whether it is correct. If the password is correct, the equipment will also unlock and allow continued operation. Before the identity authentication is passed, the security locking module will keep the equipment in the locked state to prevent unauthorized personnel from operating the equipment. Only after passing the authentication of the identity authentication module will the security locking module unlock, enabling the operator to normally control the equipment. The fingerprint recognition sensor is protected by waterproof glue to ensure that the fingerprint recognition module can still work stably in the face of environmental factors such as oil stains and moisture. When the operator is working, the drive control drive motor 6 can be pressed once to rotate one circle for one 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 adjustment rotating shaft 61 and the arc-shaped convex block 62 to rotate in the cutting combination box 7. During the rotation of the adjustment rotating shaft 61, the pressing block 76 is pressed and separated from the combined pressing groove 63 and slides out, so that the pressing block 76 fits against the outer surface of the adjustment rotating shaft 61 to maintain stability after pressing. The pressing block 76 drives the first adjustment plate 75 to descend in the cutting combination box 7. The first adjustment plate 75 drives the support rod 77 to slide down through the support rod 77. The support rod 77 slides on the second adjustment plate 78 and the cover plate 72. At the same time, the support rod 77 drives the combination mechanism and the cloth pressing mechanism 9 to descend. The combination mechanism pushes the second support spring 711 to contract and operate. The cloth pressing mechanism 9 drives the cloth pressing roller body 92 to first squeeze the fabric. During the downward pressing process, the cloth pressing roller body 92 is pressed and rotates outward to unfold. The cloth pressing roller body 92 rotates between the combination mechanisms through the connecting handle 91 and the cloth pressing mechanism 9. At the same time, the connecting handle 91 pushes the pressing rod 85 to rise. The pressing rod 85 drives the adjustment square block 84 to slide in the storage cavity 82. The adjustment square block 84 pushes the downward pressing spring 83 to contract, increasing the thrust on the connecting handle 91 and the cloth pressing roller body 92 to maintain stability and pressure during the unfolding process. The cloth pressing roller body 92 squeezes, flattens, and straightens the fabric to maintain tension. When the adjustment rotating shaft 61 drives the arc-shaped convex block 62 to contact and push the second adjustment plate 78, the second adjustment plate 78 rises smoothly in the cutting combination box 7 through the support rod 77. The second adjustment plate 78 pushes the first support spring 710 to contract. At the same time, the second adjustment plate 78 drives the cutting scissors 79 to rise. The cutting scissors 79 slide out of the knife groove 73. The cutting scissors 79 cut the straightened fabric. According to the strength and toughness of the fabric, the matching cutting scissors 79 can be replaced. After the cutting is completed, the adjustment rotating shaft 61 rotates one circle and then stops. At the same time, the arc-shaped convex block 62 is separated from the second adjustment plate 78, and the pressing block 76 slides back into the combined pressing groove 63. The first adjustment plate 75 and the second adjustment 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 cloth pressing roller body 92 is separated from the fabric. The cutting edge of the cutting scissors 79 slides back and is stored in the knife groove 73. When the cloth pressing roller body 92 is not pressed, the pressing rod 85 is reset by the elastic force of the downward pressing spring 83 on the adjustment square block 84. The pressing rod 85 pushes the connecting handle 91 to drive the cloth pressing roller body 92 to reset. The connecting handle 91 is limited by the inclined platform 81 and returns to the initial position. After the whole is completely reset, the fabric cutting is completed, and the cutting scissors 79 are stored. The clothing in the cutting area can be pulled, so as to repeat the operation. The overall operation is simple and convenient.
