Description

Technical Field

[0001] This application relates to the field of PU pad production technology, and in particular to a PU pad production and processing equipment. Background Technology

[0002] PU mats are pads made of polyurethane material. Specifically, polyurethane is the main raw material, with the addition of fillers, plasticizers, stabilizers, colorants and other auxiliary materials. They are made by uniformly mixing and coating or by calendering and extrusion on a continuous sheet substrate, such as yoga mats commonly used in fitness.

[0003] In related technologies, the production line also includes a cutting device. Sheet-shaped continuous workpieces move through the cutting device, which cuts the workpieces into segments. Then, the operators take the cut workpieces and stack them to facilitate subsequent packaging.

[0004] However, manually taking and stacking these items not only wastes manpower but also makes the process inconvenient, resulting in low operational efficiency. Summary of the Invention

[0005] To address the issues of wasted manpower and inconvenient handling leading to low operational efficiency, this application provides a PU pad production and processing equipment.

[0006] The PU pad production and processing equipment provided in this application adopts the following technical solution: A PU pad manufacturing and processing equipment includes a cutting device and a stacking device. The cutting device includes a base, a moving component, and a cutting component. Both the moving component and the cutting component are disposed on the base. The moving component is used to move the sheet-like continuous workpiece along the workpiece moving direction, and the cutting component is used to cut the sheet-like continuous workpiece into segments. The stacking device includes a gripping component and a stacking component. The stacking component includes a stacking frame and a receiving plate. The stacking frame is disposed on one side of the base. The receiving plate slides up and down relative to the stacking frame in a vertical direction. The receiving plate is used to receive and place the cut workpiece. The gripping assembly includes a gripping frame and a gripping component. The gripping frame is disposed on one side of the base and above the base and the stacking frame. The gripping component is slidably disposed on the gripping frame and reciprocates along the moving direction of the workpiece. The gripping component is used to grip the cut workpiece.

[0007] By adopting the above technical solution, the moving component conveys the sheet-like continuous workpiece to the cutting component, which cuts the workpiece into segments. Then, the gripping component picks up the cut workpiece located on the base and moves it to the stacking rack. The cut workpiece is then placed on the receiving plate to achieve automatic stacking, reducing manual operation links, improving automated processing, and thus helping to improve production efficiency.

[0008] Preferably, the gripping component includes a drive motor, an electric slider, a gripping cylinder, and a gripping claw. The drive motor is mounted on the gripping frame, the electric slider is slidably connected to the gripping frame, and the drive motor is used to drive the electric slider to reciprocate. The gripping cylinder is mounted on the electric slider, and the gripping claw is located at the end of the piston rod of the gripping cylinder. The gripping claw is used to grip the cut workpiece.

[0009] By adopting the above technical solution, the drive motor drives the electric slider to move back and forth along the gripping frame. The electric slider drives the gripping cylinder and gripping claw to move back and forth above the base and stacking frame. The gripping cylinder, according to the preset program, cooperates with the drive motor to drive the gripping claw to move. The gripping claw grips the cut workpiece and moves it from the base to the receiving plate for placement.

[0010] Preferably, the gripping assembly further includes a negative pressure fan and a connecting pipe. The negative pressure fan is located on one side of the base, and the connecting pipe is located on the negative pressure fan. The end of the connecting pipe away from the negative pressure fan is connected to the gripping claw. The gripping claw has several negative pressure through holes, and the gripping claw grips the workpiece by adsorbing negative pressure.

[0011] By adopting the above technical solution, after the workpiece is cut, the negative pressure fan runs, and a negative pressure is formed in the gripper through the connecting pipe. The workpiece after being cut into segments is adsorbed through the negative pressure through hole. Then, the drive motor and the gripping cylinder work together to drive the gripper to move the workpiece.

[0012] Preferably, the stacking assembly includes a stacking motor and a stacking screw. The stacking motor is located inside the stacking frame, the stacking frame is provided with a stacking stand, the receiving plate is provided with a receiving block, the stacking screw is rotatably connected to the stacking frame and located inside the stacking stand, the receiving block is located inside the stacking stand and threadedly connected to the stacking screw, and the stacking motor drives the stacking screw to rotate.

[0013] By adopting the above technical solution, in order to facilitate automatic counting and stacking, when the gripper moves the workpiece to the top of the receiving plate, the negative pressure fan stops running, the workpiece is placed on the receiving plate, and simultaneously, the stacking motor runs, driving the stacking screw to rotate, which drives the receiving block to move down along the stacking stand. This not only makes way for the placement of the next workpiece, but also facilitates the stacking of multiple workpieces, making it easier for subsequent packaging.

[0014] Preferably, the stacking assembly further includes a drive group and a transmission group. The drive group includes a drive rod, and the transmission group includes a transmission rod. Both the drive rod and the transmission rod are rotatably connected to the stacking frame. A main drive gear is provided on the output shaft of the stacking motor. A first drive gear and a second drive gear are provided on the drive rod. The main drive gear meshes with the first drive gear. A first transmission gear and a second transmission gear are provided on the transmission rod. The first transmission gear meshes with the second drive gear. A stacking gear is provided on the stacking screw. The second transmission gear meshes with the stacking gear.

[0015] By adopting the above technical solution, the stacking motor operates, the main drive gear drives the first drive gear to rotate, that is, drives the drive rod to rotate, thereby driving the first transmission gear to rotate, driving the stacking gear to rotate, and the stacking gear drives the stacking screw to rotate, realizing the lifting and lowering movement of the receiving block along the stacking frame.

[0016] Preferably, there are four stacking frames, stacking screws and receiving blocks, and two transmission groups, which are located at both ends of the drive rod.

[0017] By adopting the above technical solution, the drive rod rotates and drives the two transmission groups to rotate synchronously, which facilitates the synchronous rotation of the four stacking screws, thereby enabling the four receiving blocks to move synchronously. This drives the receiving plate to move up and down along the stacking frame, improving the stability of the receiving plate during its movement. This also helps to improve the stability of the entire device's operation, making the automatic stacking of workpieces smoother.

[0018] Preferably, the stacking assembly further includes a limiting upright, which is fixedly connected to the stacking frame and passes through the receiving block. When the workpiece is placed on the receiving plate, the limiting upright is in contact with the circumferential surface of the workpiece.

[0019] By adopting the above technical solution, when the gripper places the workpiece on the receiving plate, the setting of the limiting rod limits the workpiece, improves the alignment of the workpieces in the vertical direction when multiple workpieces are stacked, improves the automation level of the whole device, and facilitates subsequent integration and packaging.

[0020] Preferably, a compaction block is rotatably connected to the end of the limiting upright. When the workpieces are stacked, the compaction block is flush with the surface of the limiting upright and is in a vertical position. When the workpieces are stacked, the compaction block rotates and is perpendicular to the limiting upright, and the compaction block abuts against the workpiece.

[0021] By adopting the above technical solution, during the workpiece stacking operation, the compaction block and the limiting rod together limit the workpiece; according to the preset number of workpieces to be stacked and packaged, when the number of workpieces on the current receiving plate reaches the preset value, the compaction block rotates relative to the limiting rod and presses on the workpiece located on the top layer, so that the relative position between several workpieces is stable, which facilitates subsequent unified bundling and packaging.

[0022] Preferably, a movable rod is slidably connected inside the limiting upright, one end of the movable rod is provided with a movable toothed row, the compaction block is provided with a movable gear, the movable toothed row meshes with the movable gear, the end of the movable rod away from the movable toothed row is provided with a movable block, the receiving block moves downward along the stacking upright, and the receiving block abuts against the movable block.

[0023] By adopting the above technical solution, as the workpieces are stacked one by one, the receiving plate moves downward accordingly. When the workpieces are stacked to a preset value, the receiving block moves downward and abuts against the moving block. The moving block drives the moving rod to move downward, and the moving rod drives the moving gear row to move, thereby driving the moving gear to rotate, realizing the rotation of the compaction block relative to the limiting upright, so that the compaction block is smoothly pressed onto the workpiece, improving the stability of the stacked workpieces.

[0024] Preferably, the receiving plate has a through groove for threading packing rope.

[0025] By adopting the above technical solution, after the workpieces are stacked, the compaction block is pressed on the workpieces. At this time, the operator can use the packing rope to thread through the through groove to tie and pack the stacked workpieces, which will facilitate movement and transportation for subsequent work.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up gripping and stacking components, after the sheet-like continuous workpiece is cut into segments, the gripping component grips the workpiece located on the base by negative pressure adsorption, and then moves it to the receiving plate. The workpiece is then placed on the receiving plate in sequence to achieve automatic stacking. It has a high degree of automation, is easy to operate, saves manpower and effectively improves operating efficiency. 2. By setting up compaction blocks and through slots, once the number of workpieces stacked on the current receiving plate reaches a preset value, the compaction blocks rotate relative to the limiting uprights and press down on the workpieces located on the top layer, so that the relative positions between several workpieces are stable. Then, the operator inserts packing ropes through the through slots to quickly bundle and pack the stacked workpieces, making them easy to move and transport for the next step of processing.

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses a PU pad production and processing equipment, such as... Figure 1 and 2As shown, the device includes a cutting device and a stacking device. The cutting device includes a base 1, a moving component 2, and a cutting component 3. Both the moving component 2 and the cutting component 3 are mounted on the base 1. The moving component 2 is used to move the continuous sheet-like workpiece 9 along the moving direction of the workpiece 9, and the cutting component 3 is used to cut the continuous sheet-like workpiece 9 into segments. The stacking device includes a gripping component 4 and a stacking component 5. The gripping component 4 is used to automatically grip and move the segmented workpiece 9, and the stacking component 5 cooperates with the gripping component 4 to automatically stack the workpiece 9.

[0036] like Figure 2 and 3 As shown, the moving assembly 2 includes a first moving group and a second moving group. The first moving group includes a first motor 21, a first rotating shaft 22, and a first moving belt 23. The first motor 21 is fixedly installed inside the base 1, and the first rotating shaft 22 is rotatably connected inside the base 1. There are two first rotating shafts 22, and the first moving belt 23 is wound around the two first rotating shafts 22. The second moving group includes a second motor 24, a second rotating shaft 25, and a second moving belt 26.

The rotation of the first moving belt 23 and the second moving belt 26 drives the workpiece 9 to move forward continuously.

[0037] like Figure 2 and 3 As shown, the cutting assembly 3 includes a cutting motor 31, a rotating shaft 32, a connecting plate 35, and a cutting blade 36. The cutting motor 31 is fixed below the base 1. A drive pulley 311 is coaxially fixedly connected to the output shaft of the cutting motor 31. A driven pulley 321 is fixedly connected to one end of the rotating shaft 32. A driven belt 33 is wound around the drive pulley 311 and the driven pulley 321. A mating wheel 322 is fixedly connected to the end of the rotating shaft 32 away from the driven pulley 321. A cutting connecting rod 34 is eccentrically rotatably connected to the mating wheel 322. The connecting plate 35 is fixedly connected to the end of the cutting connecting rod 34 away from the mating wheel 322. The cutting blade 36 is detachably connected to the connecting plate 35 by bolts, which facilitates regular maintenance or replacement of the cutting blade 36.

[0038] like Figure 2 and 3As shown, the cutting motor 31 operates, driving the drive pulley 311 to rotate. Driven by the drive belt, the driven pulley 321 rotates, which in turn drives the rotating shaft 32 to rotate, facilitating speed adjustment. The rotating shaft 32 drives the mating wheel 322 to rotate, which in turn drives the cutting link 34 to move. The cutting link 34 then drives the cutting blade 36 to reciprocate. To improve the stability of the movement of the cutting link 34 and the connecting plate 35 during processing, a limiting frame 37 is fixedly connected inside the base 1 to restrict the displacement of the cutting link 34. A limiting bracket 38 is fixedly connected on the base 1, located on the side away from the cutting link 34. The limiting bracket 38 has a limiting groove for placing and moving the end of the connecting plate 35.

[0039] like Figure 4 As shown, the stacking assembly 5 includes a stacking frame 51 and a receiving plate 53. The stacking frame 51 is located on one side of the base 1 and is positioned on the side of the cutting blade 36 away from the moving assembly 2 along the moving direction of the workpiece 9. The receiving plate 53 moves vertically relative to the stacking frame 51 and is used to receive and place the workpiece 9 after it has been cut into segments.

[0040] like Figure 2 and 4 As shown, the gripping assembly 4 includes a gripping frame 41 and gripping components. The gripping frame 41 is located on one side of the base 1 and above the base 1 and the stacking rack 51. The gripping components include a drive motor 42, an electric slider 43, a gripping cylinder 44, and a gripping claw 45. The drive motor 42 is fixedly connected to the gripping frame 41, and the electric slider 43 is slidably connected to the gripping frame 41. The drive motor 42 is used to drive the electric slider 43 to reciprocate. The gripping cylinder 44 is fixedly connected to the electric slider 43, and the gripping claw 45 is fixedly connected to the end of the piston rod of the gripping cylinder 44. The gripping claw 45 is used to grip the cut workpiece 9.

[0041] like Figure 2 As shown, the gripping component 4 also includes a negative pressure fan and a connecting pipe 46. The negative pressure fan (not shown in the figure) is located on one side of the base 1. The connecting pipe 46 is fixedly connected to the negative pressure fan. The end of the connecting pipe 46 away from the negative pressure fan is connected to the gripping claw 45. The gripping claw 45 has several negative pressure through holes. The gripping claw 45 grips the workpiece 9 by adsorbing negative pressure.

[0042] like Figure 3 As shown, a pressure detector 11 is installed inside the base 1, and the pressure detector 11 is electrically connected to the negative pressure fan. When the mating wheel 322 drives the cutting link 34 to move, the end of the cutting link 34 presses against the pressure detector 11. After the pressure detector 11 detects the pressure, it immediately sends a signal to the negative pressure fan. After receiving the signal, the negative pressure fan runs. At this time, the cutting blade 36 just completes the cutting, and the gripping claw 45 grips the cut workpiece 9 by negative pressure adsorption.

[0043] like Figure 4 As shown, the stacking assembly 5 also includes a stacking motor 54, a drive group 6, a transmission group 7, and stacking screws 55. The stacking motor 54 is fixedly connected inside the stacking frame 51. Four stacking stands 52 are fixedly provided on the stacking frame 51. The stacking screws 55 are rotatably connected to the stacking frame 51 and located inside the stacking stands 52. The number of stacking screws 55 corresponds to the number of stacking stands 52. The receiving plate 53 is provided with four receiving blocks 531. The receiving blocks 531 are located inside the stacking stands 52. The receiving blocks 531 correspond one-to-one with the stacking screws 55 and are threadedly connected.

[0044] like Figure 4 As shown, a main drive gear 541 is fixedly connected to the output shaft of the stacking motor 54. The drive assembly 6 includes a drive rod 61, which is rotatably connected to the stacking frame 51. A first drive gear 62 and a second drive gear 63 are fixedly connected to the drive rod 61, and the main drive gear 541 meshes with the first drive gear 62. The transmission assembly 7 includes a transmission rod 71, which is rotatably connected to the stacking frame 51. A first transmission gear 72 and a second transmission gear 73 are fixedly connected to the transmission rod 71, and the first transmission gear 72 meshes with the second drive gear 63. A stacking gear 551 is fixedly connected to the stacking screw 55, and the second transmission gear 73 meshes with the stacking gear 551. In this embodiment, the transmission assembly 7 has two sets.

[0045] When the stacking motor 54 is running, the main drive gear 541 drives the first drive gear 62 to rotate, which in turn drives the drive rod 61 to rotate, thereby driving the first transmission gear 72 to rotate. The first transmission gear 72 drives the second drive gear 63 to rotate, which in turn drives the transmission rod 71 to rotate. Simultaneously, it drives the two transmission rods 71 ​​to rotate, thereby synchronously driving the four stacking screws 55 to rotate, so as to realize the lifting and lowering movement of the receiving block 531 along the stacking stand 52.

[0046] The receiving plate 53 has a built-in sensor, which is electrically connected to the stacking motor 54. When the gripper 45 grips the cut and segmented workpiece 9 and moves it onto the receiving plate 53, the sensor detects that a new workpiece 9 has been placed on the receiving plate 53 and sends a signal to the stacking motor 54. After receiving the signal, the stacking motor 54 runs and drives the receiving block 531 to move the receiving plate 53 down along the stacking stand 52 to make room for the subsequent stacking of workpieces 9.

[0047] like Figure 4 and 5As shown, the stacking assembly 5 also includes a limiting rod 8 and a compaction block 81. The limiting rod 8 is fixedly connected to the stacking frame 51 and passes through the receiving block 531. When the workpiece 9 is placed on the receiving plate 53, the limiting rod 8 fits against the circumferential surface of the workpiece 9, limiting the stacked workpieces 9 and improving automated operation. The compaction block 81 is rotatably connected to the end of the limiting rod 8 away from the stacking frame 51. When the workpieces 9 are stacked, the compaction block 81 is flush with the surface of the limiting rod 8 and is in a vertical position. When the workpieces 9 are stacked, the compaction block 81 rotates and is perpendicular to the limiting rod 8. The compaction block 81 abuts against the workpiece 9 on the top layer, which helps to improve the stability of the relative position between several workpieces 9 after stacking and facilitates subsequent bundling operations.

[0048] like Figure 4 and 5 As shown, the stacking assembly 5 also includes a moving rod 82, a moving gear rack 821, and a moving block 822. The moving rod 82 slides vertically within the limiting rod 8. The moving gear rack 821 is fixedly connected to one end of the moving rod 82. A moving gear 811 is fixedly connected to the compaction block 81, and the moving gear rack 821 meshes with the moving gear 811. The moving block 822 is fixedly connected to the end of the moving rod 82 away from the moving gear rack 821. As the workpieces 9 are stacked one by one, the receiving plate 53 moves downward accordingly. When the workpieces 9 are stacked to a preset value, the receiving block 531 moves downward and abuts against the moving block 822. The moving block 822 drives the moving rod 82 to move downward, and the moving rod 82 drives the moving gear rack 821 to move, thereby driving the moving gear 811 to rotate, realizing the rotation of the compaction block 81 relative to the limiting rod 8, so that the compaction block 81 can be smoothly pressed onto the workpiece 9, improving the stability of the stacked workpieces 9.

[0049] like Figure 4 and 6 As shown, to facilitate the bundling and packaging of the stacked workpieces 9, a through groove 532 is provided on the receiving plate 53 for threading packing ropes. After the workpieces 9 are stacked, the compaction block 81 is pressed onto the workpieces 9. At this time, the operator can thread the packing ropes through the through groove 532 to bundle and package the stacked workpieces 9, facilitating their movement and transportation for subsequent work.

[0050] The implementation principle of a PU pad production and processing equipment according to an embodiment of this application is as follows: The sheet-like continuous workpiece 9 is moved and conveyed by the cooperation of the first moving belt 23 and the second moving belt 26. The workpiece 9 moves to the cutting blade 36, and according to the preset program, the cutting blade 36 cuts the sheet-like continuous workpiece 9 into segments.

[0051] After the sheet-like continuous workpiece 9 is cut into segments, the gripping component 4 grips the workpiece 9 located on the base 1 by negative pressure adsorption, and then moves it to the receiving plate 53. The workpiece 9 is then placed on the receiving plate 53 in sequence to achieve automatic stacking. The automation level is high, the operation is convenient, and it saves manpower while effectively improving the operation efficiency.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
