[0020] In this embodiment, the load-bearing plate 1 is supported and shock-absorbing by the support module 2, thereby reducing external interference to the cutting module 5 when it is working. Then, clamping plates are provided on both sides of the conveyor cutting belt 9, and the leather laid on the top of the conveyor cutting belt 9 is fixed by the clamping plates to reduce the wrinkles of the leather when the cutting module 5 is working, thereby improving the integrity of the cut samples. Then, the samples cut by the cutting module 5 are adsorbed by the conveying module 6, and the transverse driving motor 407 installed on the longitudinal driving mechanism 4 enables the conveying module 6 to transport the samples from the conveyor cutting belt 9 to the conveying transmission belt 7. The cut samples are transported to the next production link by the conveying transmission belt 7, thereby improving the work efficiency by improving the continuity of production.

Then, the set supporting legs are connected and reinforced by the reinforcement plate 202 to improve the stability of the supporting legs. Then, the pressure of the load-bearing plate 1 is distributed by multiple support rods 204 to prevent the load-bearing plate 1 from being deformed under the action of gravity, thereby improving the stability of the cutting module 5 during cutting.

The longitudinal driving mechanism 4 includes a sliding bottom plate, which is slidably matched with the sliding rod body 302. A motor protection shell is provided at the top of the sliding bottom plate. A group of coaxially arranged longitudinal driving motors 409 are provided in the motor protection shell. The output end of each longitudinal driving motor 409 is connected to a longitudinal driving motor 409 through a pin shaft.

The two frames 3 and the longitudinal driving mechanism 4 are symmetrically arranged at both ends of the ball screw 402; the cutting module 5 includes a stamping module 501, a cutting nut seat 8 is provided at the top of the stamping module 501, a cutting head 502 is provided at the bottom of the stamping module 501, and also includes a material blocking assembly 503, which is arranged on the outside of the cutting head 502 (the structure and working process of the cutting module 5 have been disclosed in the patent application number CN117770578A).

[0025] In this embodiment, the hydraulic pump 10 provides power to the hydraulic lifting rod 304 to realize the lifting of the hydraulic lifting rod 304, the inner lifting shell 305 is connected to the hydraulic lifting rod 304, and the inner lifting shell 305 and the outer lifting shell 301 are slidably matched to realize the lifting of the frame 3, and then drive the cutting module 5 and the conveying module 6 to rise or fall, so as to adjust the distance between the cutting module 5 and the conveying module 6 and the conveying cutting belt 9; Then, in the initial state, the limiting telescopic rod 405 is in the shortest state. When it is necessary to adjust the distance between the cutting module 5 and the conveying module 6 in the longitudinal direction, the limiting telescopic rod 405 is extended to the longest state. During the extension process, the limiting telescopic rod 405 pushes the brake plate 406 to slide upward, so that the brake plate 406 and the longitudinal driving gear 404 gradually disengage from the meshing state, and then the longitudinal driving motor 409 drives the longitudinal driving gear 404 to rotate. Since the longitudinal driving gear 404 is engaged with the tooth groove 303 of the sliding rod body 302, the rotation of the longitudinal driving gear 404 drives the housing 401 to move along the length direction of the sliding rod body 302, thereby achieving the purpose of adjusting the distance between the cutting module 5 and the conveying module 6; When the cutting module 5 and the conveying module 6 need to be adjusted laterally, the ball screw 402 is driven to rotate by the transverse driving motor 407 installed on the upper part of the driving housing 401, and the cutting module 5 or the conveying module 6 moves along the length direction of the ball screw 402 through the cooperation between the ball screw 402 and the cutting nut seat 8 and the conveying nut seat 11.

[0026] In another embodiment, if Fig.15 As shown, the transverse drive motor 407 is connected to the transmission shaft 415 through a coupling, and an inner-rotating transmission gear 411 and an outer-rotating transmission gear 412 are arranged at intervals on the outer side surface of the transmission shaft 415 away from the transverse drive motor 407. It also includes two ball screws 402 that are symmetrical along the central axis of the transmission shaft 415. Both ends of the ball screw 402 are rotatably matched with the drive housing 401 through bearings.

[0027] In this embodiment, when it is necessary to adjust the lateral movement of different parts of the transport module 6, the middle ball screw 402 is replaced with a transmission shaft 415. Since the internal rotation transmission gear 411 and the external rotation transmission gear 412 are coaxial and both are connected to the transmission shaft 415 with a pin, the transmission shaft 415 drives the internal rotation transmission gear 411 and the external rotation transmission gear 412 in the longitudinal driving mechanism 4 on the other side to rotate. Then, the ball screw 402 is arranged on both sides of the transmission shaft 415. Since a transmission telescopic rod 410 is provided at one end of each ball screw 402, a first transmission gear 414 and a second transmission gear 413 are connected to the outside of the transmission telescopic rod 410 through a pin. Since the first transmission gear 414 is meshed with the external rotation transmission gear 412, and the second transmission gear 413 is meshed with the second transmission gear 413, the rotation directions of the two ball screws 402 are different, thereby realizing that different parts of the transport module 6 are moved.

[0030] In this embodiment, the cut leather is adsorbed by the transport units 606 in the right transport shell 601 and the left transport shell 602. Specifically, the transport servo motor 614 drives the transport rotating roller 612 at the upper part of the right transport shell 601 to rotate. Since the driving wheel is connected to the driven wheel through the transmission belt 604, the driving wheel is coaxial with the transport rotating roller 612 at the upper part of the right transport shell 601 and is connected through a pin shaft, so that the transport servo motor 614 drives the transport rotating roller 612 to rotate while driving the left transport shell 602. The driven wheel on the outside rotates, and at the same time, the driven wheel is connected to the lower transmission gear 603 through the pin shaft, thereby driving the lower transmission gear 603 to rotate, and then the meshing of the lower transmission gear 603 and the upper transmission gear 605 drives the upper transmission gear 605 to rotate, and then drives the transport rotating roller 612 in the left transport housing 602 to rotate, and then the transport transmission belt 613 connected to the transport rotating rollers 612 at different heights makes the lower transport rotating rollers 612 in the right transport housing 601 and the left transport housing 602 rotate following the upper transport rotating rollers 612; Then, the transport servo motor 614 drives the transport rotating roller 612 installed in the right transport shell 601 to rotate clockwise, and then the transmission belt 604 drives the transport rotating roller 612 in the left transport shell 602 to rotate counterclockwise, so that the material picking components on the opposite sides of the right transport shell 601 and the left transport shell 602 move toward the opposite surfaces of the right transport shell 601 and the left transport shell 602 under the action of the transport transmission belt 613, and then the longitudinal drive motor 409 and the transverse drive motor 407 in the longitudinal drive mechanism 4 control the position of the transport module 6 so that the material picking component of the transport module 6 can easily absorb the cut materials; Specifically, the sampling hydraulic box 619 and the sampling hydraulic delivery pipe 611 are connected to the hydraulic pump 10 in sequence to provide power for the movement of the sampling hydraulic rod 625, and then the gas guide seat 618, the gas delivery pipe 617 and the sampling gas delivery pipe 616 are connected to the air pressure pump in sequence to provide power for the pneumatic telescopic rod 608. When the material collection assembly moves from the opposite sides of the right transport shell 601 and the left transport shell 602 to the opposite sides of the right transport shell 601 and the left transport shell 602, the sampling hydraulic box 619 increases the pressure on the sampling hydraulic rod 625, so that the sampling liquid The length of the pressure rod 625 increases, so that the sampling sliding plate 622 installed between the sampling hydraulic rods 625 and the sampling mounting plate 609 installed on the sampling sliding plate 622 move downward, and then the pneumatic telescopic rod 608 is controlled to extend through the air guide seat 618 so that the suction cup 610 contacts and adsorbs the material, completing the process of adsorbing the material, and then the above actions are repeated in sequence until all the materials are adsorbed on the material collection components between the opposite surfaces of the right transport shell 601 and the left transport shell 602. At this time, the transport module 6 is moved from above the conveyor cutting belt 9 to above the transport transmission belt 7 through the longitudinal drive mechanism 4; Then the rotation of the transport servo motor 614 is reversed, so that the material picking assembly between the opposite surfaces of the right transport shell 601 and the left transport shell 602 moves downward and moves toward the opposite back surfaces of the right transport shell 601 and the left transport shell 602, so that the suction cup 610 and the material are separated from the tight fit state, so that the material falls on the end surface of the transport transmission belt 7 and is transported to the next process, and then the above movement is repeated until the material adsorbed on the material picking assembly between the opposite surfaces of the right transport shell 601 and the left transport shell 602 all falls on the transport transmission belt 7.

[0031] In order to realize the connection between the sampling hydraulic rod 625 and the hydraulic pump 10 and the connection between the pneumatic telescopic rod 608 and the air pressure pump, the conveying transmission belt 613 is made into a hollow shape, and a fixed frame is installed on the inner wall surface, and then the inlet and outlet valves 633 connecting the inside and the outside are installed on the opposite surface of the conveying transmission belt 613. Then, since the rotating shaft sleeves 628 are arranged at both ends of the conveying rotating roller 612 and are integrally connected, and then the nozzles 629 are arranged on the outer side of the rotating shaft sleeves 628, the rotating shaft sleeves 628 at the front end of the conveying rotating roller 612 are used to convey hydraulic oil or gas, and the rotating shaft sleeves 628 at the rear end of the conveying rotating roller 612 are used to convey gas or hydraulic oil. The sampling hydraulic delivery pipe 611 and the sampling gas delivery pipe 616 are respectively connected to different conveying transmission belts 613, so that the conveying transmission belt 613 can drive the conveying rotating rollers 612 at different heights to rotate and also serve as a conveying channel for hydraulic oil and gas; Specifically, in the initial state, the nozzle spring 641 and the in-out valve spring 652 of the nozzle 629 and the in-out valve 633 are in a compressed state, so that the nozzle 629 and the in-out valve 633 are in a closed state. When the conveying belt 613 is close to the rotating shaft sleeve 628, the nozzle valve body 634 of the nozzle 629 is inserted into the in-out valve connecting cavity 645 of the in-out valve 633. Then, with the movement of the conveying belt 613 and the cone-shaped nozzle valve body 634, the nozzle valve body 634 squeezes the valve flap 646, so that the valve flap 646 moves toward the depression on the inner wall of the in-out valve cavity 654. At the same time, the in-out valve push rod 650 of the in-out valve 633 enters the nozzle outlet 644 of the nozzle 629 and contacts the sealing valve 643. Then, with the movement of the conveying belt 613, the nozzle valve body 634 continues to move into the in-out valve cavity 654, and then Later, since the elastic coefficient of the inlet and outlet valve spring 652 is smaller than the elastic coefficient of the nozzle spring 641, the sealing valve 643 and the inlet and outlet valve push rod 650 interact with each other, and the inlet and outlet valve push rod 650 drives the inlet and outlet valve sealing plug 651 to compress the inlet and outlet valve spring 652, so that the inlet and outlet valve cavity 654 of the inlet and outlet valve 633 is connected with the inside of the conveying transmission belt 613. When the nozzle valve body 634 completely enters the inlet and outlet valve cavity 654, the nozzle push rod 649 pushes the sealing valve 643 to compress the nozzle spring 641, so that the nozzle cavity 640 is connected with the nozzle outlet 644, realizing the connection between the nozzle 629 and the inlet and outlet valve 633, so that the inlet and outlet valve 633 can be used as a switch of the nozzle 629 while the hydraulic oil or gas is in and out, that is, when the inlet and outlet valve 633 and the nozzle 629 are separated, the connection with the outside is closed, and when the inlet and outlet valve 633 and the nozzle 629 cooperate, the connecting pipeline is connected.

The flip shaft 658 is hollow and connected to the air supply pipe 617. The internal cavity of the flip shaft 658 constitutes an inlet and outlet air cavity 657. The flip shaft 658 is fixedly connected to the sampling mounting plate 609 through a pin shaft, and a swivel joint 659 is provided on the outside of the flip shaft 658.

[0035] In this embodiment, in order to improve the working efficiency of the transport module 6, the left transport assembly 627 and the right transport assembly 655 in the left transport shell 602 and the right transport shell 601 are both installed with a transport servo motor 614, so that the left transport shell 602 and the right transport shell 601 can not only transport materials together but also transport materials separately, and then combined with the longitudinal drive mechanism 4 on the right side of the fourth embodiment, the left transport shell 602 and the right transport shell 601 can be independently moved. Specifically, the inner rotation transmission gear 411 and the outer rotation transmission gear 412 coaxial with the transmission shaft 415 are driven to rotate, and then due to the first The transmission gear 414 meshes with the externally rotating transmission gear 412, and the second transmission gear 413 meshes with the internally rotating transmission gear 411, so that the ball screws 402 on both sides of the transmission shaft 415 rotate in opposite directions, and then the guide rod 1114 is retracted into the rear sleeve 1108 through the guide hydraulic telescopic rod 1113, so that the left transport housing 602 and the right transport housing 601 move in opposite directions. When the left transport housing 602 and the right transport housing 601 need to move toward each other, the movement direction of the transmission shaft 415 is reversed, so that the left transport housing 602 and the right transport housing 601 move toward each other at the same speed. When the left transport housing 602 and the right transport housing 601 need to keep moving in the same direction, the first transmission gear 414 or the second transmission gear 413 is disengaged by extending a certain transmission telescopic rod 410, and then the nut seat servo motor 1107 works, and the screw drive wheel 1103 is driven to rotate through the nut seat transmission belt 1104. Since the screw drive wheel 1103 is screwed with the screw nut seat 1110, the screw nut seat 1110 rotates, thereby pushing the left transport housing 602 or the right transport housing 601 to move in the same direction as the right transport housing 601 or the left transport housing 602; In order to further improve the working efficiency of the transport module 6, an electromagnet is provided near the bottom of the inner side of the flip frame 656, a permanent magnet is provided near the bottom of the sampling mounting plate 609 on the opposite side of the flip frame 656, the inlet and outlet air cavity 657 of the flip shaft 658 is connected with the air guide seat 618, and then connected with the suction cup 610 through the swivel joint 659. When the suction cup 610 of the material picking component absorbs the material and moves from the opposite side of the left transport shell 602 and the right transport shell 601 to the opposite side of the left transport shell 602 and the right transport shell 601 under the action of the transport transmission belt 613, the material picking component moves from the opposite side of the left transport shell 602 and the right transport shell 601 to the opposite side of the left transport shell 602 and the right transport shell 601. Fig.17 When the left side of the middle upper transport rotating roller 612 moves toward the right side, the electromagnet is energized, and the upper end surface of the sampling mounting plate 609 is flush with the upper end surface of the flip frame 656 under the action of the electromagnet and the permanent magnet, so that the flip shaft 658 can be used as a rotating shaft and also as a gas delivery pipeline; When the material picking assembly moves to the highest point and moves downward, the magnetic pole direction of the electromagnet on the flip frame 656 is reversed, and then a flipping torque is generated under the action of the magnetic field force and gravity, so that the sampling mounting plate 609 flips around the flip axis 658, thereby flipping the pneumatic telescopic rod 608 and the suction cup 610 toward the sampling sliding plate 622, so that the pneumatic telescopic rod 608 changes from a vertical upward state to a vertical downward state, and then the magnetic pole of the electromagnet in the flip frame 656 is changed again to stabilize the state of the sampling mounting plate 609 after flipping, so that the transport servo motor 614 only needs to rotate in one direction, thereby reducing energy consumption and improving work efficiency.
