[0020] The following is combined with Figure 1-Figure 2 This application is described in further detail.

[0021] The present application embodiment discloses a leather measuring device. Figure 1 and Figure 2 A leather measuring device includes a body 1, which is horizontally mounted on the ground, and the length direction of the body 1 extends along the ground. A conveyor belt 2 is arranged on the body 1, and the conveyor belt 2 is used to convey leather. In this embodiment, the conveyor belt 2 is driven by a motor, and the motor is correspondingly installed on the side wall of the body 1. In addition, an induction detection mechanism 3 is mounted on the body 1, and the induction detection mechanism 3 is used to detect leather. The induction detection mechanism 3 is located in the middle of the body 1 and is mounted above the conveyor belt 2. When the leather is placed on the upper surface of the conveyor belt 2, the motor is started, and the conveyor belt 2 moves, and then the leather is sent to the bottom of the induction detection mechanism 3, so that the leather is measured.

[0022] It should be noted that the sensing detection mechanism 3 is usually composed of multiple key components, including but not limited to sensors, signal processors and data processing units. In the leather measuring device, sensors (such as optical sensors, pressure sensors or proximity sensors) are installed above the conveyor belt 2 to capture the physical properties of the leather, such as size, thickness, color or texture. The signal processor is responsible for converting the raw signals collected by the sensor into analyzable electrical signals, while the data processing unit analyzes these electrical signals to determine the specific parameters of the leather.

[0023] The detection process is usually as follows: When the leather is sent to the bottom of the inductive detection mechanism 3 by the conveyor belt 2, the sensor starts working to capture the surface information of the leather. For example, the optical sensor can measure the reflectivity of the leather to determine its color and texture; the pressure sensor can measure the thickness of the leather at a specific point; the proximity sensor can detect the edge of the leather to determine its size. These sensors convert the captured information into electrical signals, and then the signal processor amplifies, filters and digitizes these signals to eliminate noise and improve signal quality. Finally, the data processing unit analyzes the processed signals, calculates the size, thickness, color and other parameters of the leather, and stores or displays these data for use by operators or subsequent processing systems.

[0024] Therefore, the induction detection mechanism 3 in the embodiment of the present application is a conventional technical means and will not be elaborated on here.

[0025] On the other hand, a lifting mechanism 4 is provided on one side of the body 1, and the lifting mechanism 4 is used to carry and lift a number of stacked leathers. A grabbing mechanism is also provided at the front end of the body 1, and the grabbing mechanism is used to realize the transfer of leather between the lifting mechanism 4 and the conveyor belt 2.

[0026] Specifically, the lifting mechanism 4 includes a load-bearing frame 41 and a load-bearing plate 42. The cross-section of the load-bearing frame 41 is L-shaped. The load-bearing frame 41 is erected on the ground. The load-bearing frame 41 is located on one side of the body 1. The load-bearing plate 42 is horizontally arranged. The load-bearing plate 42 is slidably arranged on the load-bearing frame 41 along the vertical direction. The upper surface of the supporting plate corresponds to a supporting tray, and a number of pieces of leather are stacked on the tray.

[0027] In addition, the grabbing mechanism includes a horizontal motion module 5 and a clamping cylinder 6. The horizontal motion module 5 is arranged on the upper surface of the body 1. The clamping cylinder 6 is used to clamp the leather. The clamping cylinder 6 is installed on the horizontal motion module 5. The horizontal motion module 5 drives the clamping cylinder 6 to move. A collecting box 7 is arranged at the rear end of the body 1, and the collecting box 7 is located below the conveyor belt 2.

[0028] In summary, first, the stacked leather is placed on a tray, and the tray is placed on the carrying plate 42 of the lifting mechanism 4. The carrying plate 42 slides in the vertical direction and is supported by the carrying frame 41. When the leather needs to be processed, the carrying plate 42 rises to lift the tray together with the leather to a suitable height so that the grabbing mechanism can operate.

[0029] Furthermore, the horizontal motion module 5 and the clamping cylinder 6 in the grabbing mechanism work together. The horizontal motion module 5 moves on the upper surface of the machine body 1, driving the clamping cylinder 6 to reach above the lifting mechanism 4. The clamping cylinder 6 extends to clamp the leather on the tray, and then the horizontal motion module 5 drives the clamping cylinder 6 to move toward the conveyor belt 2 to accurately place the leather on the conveyor belt 2.

[0030] After the leather is placed on the conveyor belt 2, the conveyor belt 2 driven by the motor starts to move and delivers the leather to the bottom of the induction detection mechanism 3. The induction detection mechanism 3 performs real-time detection on the leather, including measurement of parameters such as size, thickness, color, etc., to ensure accurate measurement of the leather.

[0031] Finally, after the measurement is completed, the conveyor belt 2 continues to move to deliver the leather to the top of the collection box 7 at the rear end of the machine body 1. The leather falls from the conveyor belt 2 and enters the collection box 7, completing the entire measurement and collection process.

[0032] In this process, the horizontal motion module 5 mainly plays the role of controlling the horizontal motion of the clamping cylinder 6. Specifically, the horizontal motion module 5 includes a driving motor 51, a screw 52, ​​a guide rod 53 and a sliding seat 54. A bearing seat 1a is vertically fixed on the machine body 1. In this embodiment, there are four bearing seats 1a, which are arranged in a matrix. The driving motor 51 is installed on the bearing frame 41. The screw 52 is rotatably supported on two oppositely arranged bearing seats 1a. The screw 52 is located above the conveyor belt 2 and is arranged along the width direction of the machine body 1. At the same time, the guide rod 53 and the screw 52 are parallel to each other, the sliding seat 54 is slidably arranged on the screw 52 and the guide rod 53, the sliding seat 54 is threadedly matched with the screw 52, ​​and the clamping cylinder 6 is installed on the sliding seat 54.

[0033] Therefore, the driving motor 51 is started, driving the screw 52 to rotate. Since the sliding seat 54 is threadedly matched with the screw 52, ​​the rotation of the screw 52 causes the sliding seat 54 to slide along the direction of the screw 52 and the guide rod 53. The guide rod 53 ensures the linear motion of the sliding seat 54, thereby realizing the precise horizontal movement of the sliding seat 54. The clamping claw cylinder 6 is installed on the sliding seat 54 and moves with the movement of the sliding seat 54 to complete the leather grabbing and placing operations. This process ensures the precise transmission of the leather during the measurement process, and improves the degree of automation and measurement efficiency.

[0034] Furthermore, two groups of screw rods 52, guide rods 53, sliding seats 54 and clamping cylinders 6 are provided. The two groups of screw rods 52 are parallel to each other. A pulley transmission mechanism is provided between the two groups of screw rods 52. The two groups of guide rods 53 are parallel to each other. The two groups of sliding seats 54 are symmetrically arranged. The two groups of clamping cylinders are respectively installed on the two groups of sliding seats 54 in a one-to-one manner. The two groups of clamping cylinders act on both sides of the edge of the leather respectively.

[0035] Therefore, by setting up two sets of parallel screw rods 52, guide rods 53, sliding seats 54 and clamping claw cylinders 6, the leather edge is synchronously grasped and stably transported on both sides. The two sets of screw rods 52 are linked by a pulley transmission mechanism to ensure the synchronous movement of the two sets of clamping claw cylinders 6, thereby improving the accuracy and stability of leather grasping. This symmetrical arrangement can effectively prevent the leather from being offset or deformed during the transmission process, ensuring the accuracy of measurement and the efficiency of leather processing.

[0036] Correspondingly, after the uppermost leather is grabbed, the carrying plate 42 needs to be lifted. In the present embodiment, this action is performed by the driving motor 51 .

[0037] Specifically, a transmission assembly 8 is provided between the carrier plate 42 and the driving motor 51, and the transmission assembly 8 includes a transmission gear 81 and a transmission rack 82. The transmission gear 81 is rotatably supported on the carrier frame 41, and the driving motor 51 drives the transmission gear 81 to rotate in one direction. The transmission rack 82 meshes with the transmission gear 81, and the transmission rack 82 is fixed on the carrier plate 42, and the transmission rack 82 is arranged in the vertical direction. Therefore, when the driving motor 51 is started, the transmission gear 81 is rotated, and because the transmission rack 82 meshes with the transmission gear 81, the transmission rack 82 can move in the vertical direction, thereby lifting the carrier plate 42.

[0038] During this process, the movement of the clamping cylinder 6 is controlled by the driving motor 51 to be a reciprocating motion. After the clamping cylinder 6 clamps the leather, when it moves toward the side away from the supporting plate 42, the supporting plate 42 needs to be lifted accordingly. After the clamping cylinder 6 moves to the end of the stroke, the output shaft of the driving motor 51 needs to be reversed to control the clamping cylinder 6 to move toward the supporting plate 42. At this time, the transmission gear 81 needs to remain stationary so that the supporting plate 42 can maintain a relatively horizontal position.

[0039] To this end, an inner ratchet mechanism 9 is provided on the carrier 41 , and the output shaft of the drive motor 51 drives the inner wheel of the inner ratchet mechanism 9 to rotate, and the outer wheel of the inner ratchet mechanism 9 is coaxially fixed with the transmission gear 81 to realize one-way transmission between the output shaft of the drive motor 51 and the transmission gear 81 .

[0040] It should be noted that the inner ratchet mechanism 9 in the embodiment of the present application is mainly composed of an inner wheel and an outer wheel, wherein the inner wheel is connected to the output shaft of the driving motor 51, and the outer wheel is coaxially fixed with the transmission gear 81. The principle of one-way transmission lies in the special design between the inner wheel and the outer wheel: when the driving motor 51 drives the inner wheel to rotate in the positive direction, the inner wheel pushes the outer wheel to rotate together through the ratchet, thereby driving the transmission gear 81 to rotate and realize the lifting of the bearing plate 42. However, when the driving motor 51 needs to be reversed, the rotation direction of the inner wheel is opposite to that before. At this time, the ratchet on the inner wheel will be disengaged from the ratchet on the outer wheel, so that the inner wheel can be reversed freely without driving the outer wheel and the transmission gear 81 to rotate, thereby ensuring that the bearing plate 42 can be maintained in a relatively horizontal position, achieving the effect of one-way transmission. This design ensures that during the reciprocating motion of the clamping cylinder 6, the bearing plate 42 can be stably lifted or kept stationary as needed, thereby improving the automation and accuracy of the leather processing process.

[0041] Furthermore, in order to improve the stability of transmission between the output shaft of the drive motor 51 and the transmission gear 81, the present application also adopts the following solution.

[0042] Specifically, the driving motor 51 adopts a dual-axis servo motor, one of the output shafts of the driving motor 51 is coaxially fixed with the screw 52, ​​and the other output shaft of the driving motor 51 is coaxially fixed with the worm 11, and the supporting frame 41 rotates to carry the worm wheel 10, the worm 11 penetrates the supporting frame 41, and the worm wheel 10 and the worm 11 are meshed with each other, and the worm wheel 10 is coaxially fixed with the inner wheel of the inner ratchet mechanism 9.

[0043] Therefore, in the present solution, a dual-axis servo motor is used as a driving source, wherein one of the output shafts is directly fixed coaxially with the screw 52, ​​and is used to drive the screw 52 to rotate, thereby controlling the horizontal movement of the clamping cylinder 6. The other output shaft is fixed with a worm 11, and the worm 11 is meshed with the worm wheel 10 on the carrier 41. The worm wheel 10 not only cooperates with the worm 11, but is also coaxially fixed with the inner wheel of the inner ratchet mechanism 9. This design utilizes the self-locking characteristics of the worm wheel 10 and the worm 11, that is, the worm 11 can drive the worm wheel 10 to rotate, but the worm wheel 10 cannot reversely drive the worm 11, which ensures the stability and accuracy of the transmission process. When the dual-axis servo motor drives the worm 11 to rotate, the worm wheel 10 rotates accordingly, thereby driving the inner wheel of the inner ratchet mechanism 9 to rotate, realizing one-way transmission, and controlling the lifting of the carrier plate 42. At the same time, the self-locking characteristics of the worm wheel 10 and the worm 11 prevent unnecessary displacement of the support plate 42 due to external forces during the movement of the jaw cylinder 6, thereby improving the stability and reliability of the entire system and ensuring precise control and efficient operation of the leather processing process.

[0044] On the other hand, when the supporting plate 42 moves upward to the end of its stroke, it is necessary to reset the supporting plate 42, that is, to disengage the transmission gear 81 from the transmission rack 82, so as to control the falling of the supporting plate 42. For this purpose, a disengagement mechanism 12 is provided between the supporting plate 42 and the supporting frame 41, and the disengagement mechanism 12 is used to realize the disengagement and resetting of the transmission gear 81 and the transmission rack 82.

[0045] Specifically, the disengagement mechanism 12 includes a driving cylinder 121, a slider 122 and a return spring 123. The driving cylinder 121 is installed on the side wall of the carrier frame 41. A push plate 1211 is fixed to the end of the piston rod of the driving cylinder 121. The side wall of the push plate 1211 abuts against the side wall of the carrier plate 42. A slide groove 1b is opened on the carrier frame 41 in the vertical direction. The slider 122 is slidably arranged in the slide groove 1b along the vertical direction. The two ends of the return spring 123 are respectively fixed to the side wall of the carrier plate 42 and the side wall of the slider 122. When the piston rod of the driving cylinder 121 is extended, the push plate 1211 pushes the carrier plate 42 to slide horizontally, the return spring 123 is stretched, the transmission rack 82 and the transmission gear 81 are disengaged from each other, and the carrier plate 42 slides down in the vertical direction.

[0046] Therefore, when the load-bearing plate 42 reaches the highest point of the stroke, the piston rod of the driving cylinder 121 extends out, pushing the push plate 1211, thereby causing the load-bearing plate 42 to slide in the horizontal direction. This horizontal movement causes the transmission rack 82 on the load-bearing plate 42 to disengage from the transmission gear 81. At this time, the return spring 123 is stretched and stores elastic potential energy. Due to the disengagement of the transmission rack 82 from the transmission gear 81, the load-bearing plate 42 loses its vertical support, and thus slides in the vertical direction under the action of gravity to achieve reset. When the load-bearing plate 42 falls to a certain position, the piston rod of the driving cylinder 121 contracts, and the elastic force of the return spring 123 begins to play a role, pushing the load-bearing plate 42 to move toward the body 1 until the transmission rack 82 re-engages with the transmission gear 81, completing the reset process.

[0047] Furthermore, a telescopic rod 1c is hinged on the carrier frame 41, one end of the telescopic rod 1c is hinged to the carrier plate 42, and the telescopic rod 1c is used to support the carrier plate 42. Specifically, when the carrier plate 42 needs to be lifted, the telescopic rod 1c gradually extends due to its telescopic characteristics, thereby lifting the carrier plate 42 to a desired height. When the carrier plate 42 is in a lifted state, the telescopic rod 1c remains in an extended state, providing stable support for the carrier plate 42, ensuring that the carrier plate 42 remains horizontal during the leather processing process, and avoiding tilting or displacement due to gravity or external forces. When the carrier plate 42 needs to be reset, the telescopic rod 1c contracts to reduce support for the carrier plate 42, allowing the carrier plate 42 to slide down in the vertical direction under the action of gravity to achieve reset.

[0048] In addition, a connecting seat 421 is provided between the transmission rack 82 and the bearing plate 42. The connecting seat 421 is provided in a triangular shape. The connecting seat 421 is fixedly connected to the transmission rack 82 and the bearing plate 42, respectively. The connecting seat 421 is used to strengthen the connection strength between the transmission rack 82 and the bearing plate 42. Specifically, the triangular connecting seat 421 provided between the bearing plate 42 and the transmission rack 82 is designed to strengthen the connection strength between the transmission rack 82 and the bearing plate 42. The triangular structure of the connecting seat 421 provides an additional support point, which can effectively disperse and withstand the force generated during the transmission process, and avoid structural damage caused by the concentrated force.

[0049] The implementation principle of a leather measuring device in the embodiment of the present application is as follows: In summary, first, the stacked leather is placed on a tray, and the tray is placed on the carrying plate 42 of the lifting mechanism 4. The carrying plate 42 slides in the vertical direction and is supported by the carrying frame 41. When the leather needs to be processed, the carrying plate 42 rises to lift the tray together with the leather to a suitable height so that the grabbing mechanism can operate.

[0050] Furthermore, the horizontal motion module 5 and the clamping cylinder 6 in the grabbing mechanism work together. The horizontal motion module 5 moves on the upper surface of the machine body 1, driving the clamping cylinder 6 to reach above the lifting mechanism 4. The clamping cylinder 6 extends to clamp the leather on the tray, and then the horizontal motion module 5 drives the clamping cylinder 6 to move toward the conveyor belt 2 to accurately place the leather on the conveyor belt 2.

[0051] After the leather is placed on the conveyor belt 2, the conveyor belt 2 driven by the motor starts to move and delivers the leather to the bottom of the induction detection mechanism 3. The induction detection mechanism 3 performs real-time detection on the leather, including measurement of parameters such as size, thickness, color, etc., to ensure accurate measurement of the leather.

[0052] Finally, after the measurement is completed, the conveyor belt 2 continues to move to deliver the leather to the top of the collection box 7 at the rear end of the machine body 1. The leather falls from the conveyor belt 2 and enters the collection box 7, completing the entire measurement and collection process.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
