Description

Technical Field

[0001] The present application relates to the technical field of punching machines, and in particular to a punching machine for cotton bale processing. Background Art

[0002] During the processing of foam, it is necessary to use a punching machine to punch holes on its surface to improve the air permeability and moisture absorption of the foam, such as for making insoles, sports pads, etc. In addition, after the foam is punched, the surface tension of the foam can be reduced to a certain extent, making the foam softer and easier to bend, which can improve the use effect and comfort of the product in some applications.

[0003] In the prior art, the punching machine includes a machine platform and multiple punches. The machine platform has a punching station. A lifting plate is slidably installed in the punching station. Multiple punches are set on the lifting plate. The foam is transported to the punching station. The lifting plate is lifted and lowered by a cylinder or a motor to drive the punch to punch the foam.

[0004] However, in actual punching operations, when the punch is lifted off the foam after the punching action is completed, the punch fits tightly against the hole wall of the foam, and there is a large friction force, so that when the punch is lifted off, the foam is lifted up together, causing the position of the foam to shift. Manual adjustment is required before punching can continue, which is time-consuming and labor-intensive, and reduces work efficiency. Therefore, further improvement is needed. Summary of the invention

[0005] In order to improve the punching efficiency of foam, the present application provides a punching machine for cotton bale processing.

[0006] The present application provides a punching machine for cotton bale processing, which adopts the following technical solution: A punching machine for cotton bale processing comprises a machine platform and a punch, the machine platform having a punching station, a lifting plate being slidably installed in the punching station, the punch being arranged on the lifting plate, the machine platform being respectively provided with a lifting assembly for driving the lifting plate to lift and lower, and a conveying assembly for conveying foam; a spray pipe for conveying lubricant is rotatably installed on the machine platform, the spray pipe is located on one side of the lifting plate, a plurality of spray heads are arranged at intervals on the peripheral wall of the spray pipe, and the machine platform is provided with a driving assembly for driving the spray pipe to rotate.

[0007] By adopting the above-mentioned technical scheme, through the arrangement of the spray pipe, the nozzle and the driving assembly, the foam is transported to the punching station through the conveying assembly. In this process, the spray pipe is driven to rotate by the driving assembly, so that the nozzle rotates around the central axis of the spray pipe, which can expand the spray range of the nozzle, and make the lubricant sprayed by the nozzle act on the punch surface and the foam surface respectively to lubricate the punch and the foam, reduce the friction between the punch and the foam hole wall when the punch is lifted off the foam after the foam punching action is completed, thereby reducing the possibility that the punch will lift up the foam when the punch is lifted off, thereby improving the punching efficiency of the foam.

[0009] By adopting the above technical scheme, through the arrangement of the first gear, the first rack and the synchronous parts, the first rotating rod and the spray pipe can rotate synchronously under the action of the synchronous parts, so that when the lifting plate is lifted or lowered, the spray pipe can be driven to rotate; during the actual spraying process of the nozzle, when the lifting plate is lifted, the nozzle rotates toward the side of the spray pipe close to the lifting plate to spray the lubricant on the punch of the lifting plate, and when the lifting plate is lowered, the nozzle rotates toward the side of the spray pipe away from the lifting plate, and the lubricant can be sprayed on the foam surface during the rotation, which greatly improves the spraying range of the nozzle, and can spray the lubricant on the surface of the punch and the surface of the foam respectively according to the lifting and lowering of the lifting plate, thereby improving the lubrication effect of the overall structure.

[0010] Optionally, a mounting ring is provided on the machine platform, the spray pipe is passed through the mounting ring and is rotatably connected to the mounting ring, a connecting arc groove is provided on the outer peripheral wall of the spray pipe which is connected to the inside of the spray pipe, and the connecting arc groove is arranged in an arc shape around the central axis of the spray pipe; the machine platform is connected to a liquid inlet pipe for supplying lubricant, and the outlet end of the liquid inlet pipe passes through the inner peripheral wall of the mounting ring; when the lifting plate is lifted or lowered, the outlet end of the liquid inlet pipe is connected to the connecting arc groove, and when the lifting plate is lifted to the highest position or lowered to the lowest position, a misalignment is formed between the outlet end of the liquid inlet pipe and the connecting arc groove.

[0011] By adopting the above-mentioned technical scheme, through the setting of the mounting ring and the connecting arc groove, and the cooperation of the mounting ring and the connecting arc groove, the nozzle can spray lubricant outward during the lifting or lowering process of the lifting plate to lubricate the punch and the foam; when the lifting plate is lifted to the highest position or lowered to the lowest position, a misalignment is formed between the outlet end of the liquid inlet pipe and the connecting arc groove, thereby closing the liquid inlet pipe and stopping the supply of lubricant to the nozzle (that is, the nozzle stops spraying); on the other hand, when the foam punching is completed and the next foam needs to be replaced for punching, during this period, the lifting plate can be lifted to the highest position or lowered to the lowest position, and the nozzle can be closed to provide installation time for the next foam, which can reduce the waste of lubricant, enable the nozzle to achieve the effect of automatic opening and closing, and improve the convenience of opening and closing the nozzle.

[0012] Optionally, a second rotating rod is rotatably installed on the machine platform, and the first rotating rod and the second rotating rod are coaxially arranged; the conveying assembly includes a conveying disc, a second gear, a second rack and a linkage member, the conveying disc is slidably installed on the machine platform, and the conveying disc has an installation station for installing foam; the second gear is coaxially arranged on the outer peripheral wall of the second rotating rod, the second rack is connected to the conveying disc, and the second gear and the second rack are meshed for transmission; the linkage member is arranged between the first rotating rod and the second rotating rod, and when the lifting plate is lifted, the linkage member causes the first rotating rod and the second rotating rod to be circumferentially linked, and the conveying disc moves toward the punching station, and when the lifting plate is lowered, the first rotating rod and the second rotating rod are disengaged from each other.

[0013] By adopting the above technical solution, through the arrangement of the conveying plate, the second gear, the second rack and the linkage, when the lifting plate is lifted, the conveying plate is displaced toward the punching station under the action of the second gear and the second rack, thereby conveying the foam at the installation station to the punching station for punching; the lifting plate is driven down, so that the punch punches the foam, and during this process, the first rotating rod and the second rotating rod are disengaged from each other, so that the conveying plate remains stationary; after one punching is completed, the lifting plate is lifted off, and the conveying plate can continue to displace for a period of time, so that the surface of the foam can continue to be punched, and this process is repeated, so that the surface of the foam is covered with punching holes, which greatly improves the operational convenience of the overall structure.

[0014] Optionally, the linkage member includes a linkage sleeve, a ratchet, a pawl and a torsion spring, the linkage sleeve is coaxially arranged at one end of the first rotating rod close to the second rotating rod, the ratchet is coaxially arranged at one end of the second rotating rod close to the first rotating rod, one end of the pawl is hinged to the inner circumferential wall of the linkage sleeve, the torsion spring is arranged between the linkage sleeve and the pawl, and the torsion spring normally causes the pawl to engage with the ratchet.

[0015] By adopting the above technical solution, through the arrangement of the linkage sleeve, ratchet, pawl and torsion spring, when the lifting plate is lifted, the first rotating rod is driven to rotate (that is, the linkage sleeve is driven to rotate), and the linkage sleeve pushes the ratchet to rotate through the pawl, so that the second rotating rod can rotate synchronously with the first rotating rod (that is, the first rotating rod and the second rotating rod are circumferentially linked), thereby driving the conveying plate to move a distance; when the lifting plate descends and forces the punch to punch the foam, the first rotating rod is reversed (that is, the linkage sleeve is reversed), and the pawl cannot push the ratchet to rotate, thereby causing the first rotating rod and the second rotating rod to disengage from each other, so that when the lifting plate is descended, the conveying plate can remain stationary, so that the punch can punch the foam on the conveying plate, which greatly improves the operational convenience of the overall structure.

[0016] Optionally, a plurality of pawls are spaced apart around the central axis of the linkage sleeve, the torsion springs are arranged corresponding to the number of pawls, and the linkage sleeve is provided with an unlocking assembly, which is used to drive all pawls to disengage from the ratchet wheel simultaneously.

[0017] By adopting the above technical solution and setting the unlocking component, on the one hand, by setting a plurality of pawls, the plurality of pawls act on the ratchet wheel at the same time, so as to increase the force application point of the linkage sleeve on the ratchet wheel, thereby improving the stability of the overall structure and reducing the possibility of damage to the pawl; on the other hand, when the surface of the foam is covered with punching holes (that is, after the entire foam is punched), the unlocking component is used to force all the pawls to disengage from the ratchet wheel at the same time, at which time the operator can retract the conveyor disc, restore the conveyor disc to its initial position and install the next foam.

[0019] By adopting the above-mentioned technical solution, the unlocking ring and the pull rod are set to drive the unlocking ring to rotate. The unlocking ring pulls all the pawls through multiple pull rods, forcing the pawls to disengage from the ratchet wheel, so that the first rotating rod and the second rotating rod can be separated from each other, thereby improving the operational convenience of the overall structure.

[0020] Optionally, a limit block is provided on the outer wall of the linkage sleeve, and a limit hole is opened in the limit block; a force rod is slidably installed on the outer wall of the unlocking ring, and when the unlocking ring drives all pawls to disengage from the ratchet wheel, the force rod rotates to a state relative to the limit hole.

[0021] By adopting the above-mentioned technical solution, through the setting of the limit block and the force rod, the force rod is used for the operator to hold so as to drive the unlocking ring to rotate. When the unlocking ring forces all the pawls to disengage from the ratchet wheel, the force rod is pushed to force one end of the force rod to be inserted into the limit hole to fix the position of the unlocking ring, thereby keeping the ratchet wheel and pawl disengaged from each other, so that the operator can perform the retraction operation on the conveyor disc and improve work efficiency.

[0022] Optionally, the spray pipe is rotatably and slidably installed on a mounting ring, and the mounting ring is provided with a guide member. When the spray pipe rotates, the guide member drives the spray pipe to slide back and forth along its own axis.

[0023] By adopting the above-mentioned technical solution and setting the guide part, the spray pipe is driven to rotate during the lifting and lowering process of the lifting plate to expand the spraying range of the nozzle. During this process, the guide part forces the spray pipe to slide back and forth along its own axis, further increasing the spraying range of the nozzle and improving the lubrication effect on the punch head and foam.

[0024] Optionally, a guide groove is provided on the outer wall of the spray pipe, and the guide groove is arranged in a ring shape around the central axis of the spray pipe, and the guide groove has two reversing points, and the two reversing points are arranged at intervals along the central axis of the spray pipe; the guide member includes a guide column, one end of the guide column is connected to the inner wall of the mounting ring, and the other end is slidably inserted in the guide groove.

[0025] By adopting the above-mentioned technical solution and setting the guide column and the guide groove, during the rotation of the spray pipe, the guide column slides in the guide groove, and the guide column can push the inner wall of the guide groove to drive the spray pipe to slide back and forth along its own central axis, thereby increasing the spray range of the nozzle and improving the operational convenience of the overall structure.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the arrangement of the spray pipe, the nozzle and the driving assembly, the foam is transported to the punching station through the conveying assembly. In this process, the spray pipe is driven to rotate by the driving assembly, so that the nozzle rotates around the central axis of the spray pipe, which can expand the spray range of the nozzle, so that the lubricant sprayed by the nozzle acts on the surface of the punch and the surface of the foam respectively, so as to lubricate the punch and the foam, reduce the friction between the punch and the foam hole wall when the punch is lifted off the foam after the punching action on the foam is completed, thereby reducing the possibility that the punch will lift up the foam when the punch is lifted off, and improving the punching efficiency of the foam; 2. Through the arrangement of the mounting ring and the connecting arc groove, and the cooperation of the mounting ring and the connecting arc groove, the nozzle can spray lubricant outward during the lifting or lowering process of the lifting plate to lubricate the punch and the foam; when the lifting plate is lifted to the highest position or lowered to the lowest position, the outlet end of the liquid inlet pipe and the connecting arc groove are misaligned, so that they are closed to the liquid inlet pipe, and the lubricant is stopped from being supplied to the nozzle (that is, the nozzle stops spraying), which can reduce the waste of lubricant, enable the nozzle to achieve the effect of automatic opening and closing, and improve the convenience of opening and closing the nozzle; 3. Through the arrangement of the linkage sleeve, ratchet, pawl and torsion spring, when the lifting plate is lifted, the first rotating rod is driven to rotate (that is, the linkage sleeve is driven to rotate), and the linkage sleeve pushes the ratchet to rotate through the pawl, so that the second rotating rod can rotate synchronously with the first rotating rod (that is, the first rotating rod and the second rotating rod are circumferentially linked), thereby driving the conveying disc to move a certain distance; when the lifting plate descends and forces the punch to punch the foam, the first rotating rod is reversed (that is, the linkage sleeve is reversed), and the pawl cannot push the ratchet to rotate, thereby causing the first rotating rod and the second rotating rod to disengage from each other, so that when the lifting plate descends, the conveying disc can remain stationary, so that the punch can punch the foam on the conveying disc, which greatly improves the operational convenience of the overall structure.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 -Attached Fig.11 This application is described in further detail.

[0030] Embodiment 1: The embodiment of the present application discloses a punching machine for cotton bale processing.

[0031] Reference Figure 1 , Figure 2 A punching machine for cotton bale processing includes a machine table 1 and a punch 2. The machine table 1 has a punching station 11, and the foam 8 is transported to the punching station 11 for punching operation; a lifting plate 12 is slidably installed in the punching station 11, and the plate surface of the lifting plate 12 is horizontally arranged. The punch 2 is fixedly installed on the lower plate surface of the lifting plate 12. In this embodiment, the number of punches 2 is set to be multiple, and the multiple punches 2 are evenly distributed along the lower plate surface of the lifting plate 12. The multiple punches 2 are slidably installed on the machine table 1 through the lifting plate 12 so that they can be lifted and lowered.

[0032] Reference Figure 1 , Figure 2 The machine 1 is provided with a lifting assembly 3, which is used to drive the lifting plate 12 to rise and fall. In this embodiment, the lifting assembly 3 includes a plurality of lifting cylinders, the cylinder bodies of which are fixedly mounted on the machine 1 and located above the punching station 11, and the piston rods of which are fixedly connected to the upper surface of the lifting plate 12, so as to drive the lifting plate 12 to descend or rise by extending or retracting the piston rods of the lifting cylinders.

[0033] Reference Figure 1The machine 1 is provided with a conveying assembly 4, which is used to convey the foam 8 to the punching station 11 for punching operation; in this embodiment, the conveying assembly 4 includes a conveyor belt 47 and a drive motor 48, and the machine 1 is rotatably installed with multiple conveying rollers 17, the conveyor belt 47 is wound around all the conveying rollers 17, and the drive motor 48 is fixedly installed on the machine 1, and the output shaft of the drive motor 48 is coaxially connected to one of the conveying rollers 17, so that the conveyor belt 47 can be used to convey the foam 8; it should be noted that in order to prevent the foam 8 from being contaminated, in this embodiment, during the conveying process of the foam 8, a layer of pad 81 is covered on the surface of the foam 8 to cover the foam 8.

[0034] Reference Figure 1 , Figure 2 A mounting ring 14 is fixedly installed on the machine 1. Two mounting rings 14 are provided. The two mounting rings 14 are arranged at intervals along the width direction of the conveyor belt 47. The two mounting rings 14 are both located on one side of the lifting plate 12; a spray pipe 5 for conveying lubricant is installed between the two mounting rings 14. The spray pipe 5 is sequentially passed through the two mounting rings 14 and is rotatably connected with the mounting rings 14. The spray pipe 5 is rotatably installed on the machine 1 through the two mounting rings 14.

[0035] In this embodiment, a nozzle 51 is fixedly installed on the peripheral wall of the spray pipe 5. The nozzle 51 is configured as an atomizing nozzle 51. There are multiple nozzles 51, which are arranged at intervals along the length direction of the spray pipe 5. The inlet end of each nozzle 51 is connected to the interior of the spray pipe 5.

[0036] Reference Figure 2 , Figure 3 A first rotating rod 13 is rotatably installed on the machine 1. The first rotating rod 13 is located on one side of the lifting plate 12 close to the spray pipe 5. The length direction of the first rotating rod 13 is arranged parallel to the length direction of the spray pipe 5. The machine 1 is provided with a driving assembly 6 for driving the spray pipe 5 to rotate. The driving assembly 6 includes a first gear 61, a first rack 62 and a synchronous member. The first gear 61 is coaxially fixed to the outer peripheral wall of the first rotating rod 13, the first rack 62 is vertically arranged, and the lower end of the first rack 62 is fixedly connected to the upper plate surface of the lifting plate 12, and the first gear 61 and the first rack 62 are meshed for transmission.

[0037] A synchronous member is arranged between the first rotating rod 13 and the spray pipe 5 to drive the first rotating rod 13 and the spray pipe 5 to rotate synchronously. In this embodiment, the synchronous member includes a transmission gear 63 and a toothed belt 64. Two transmission gears 63 are provided, one of which is coaxially fixed to the outer peripheral wall of one end of the first rotating rod 13, and the other transmission gear 63 is coaxially fixed to the outer peripheral wall of one end of the spray pipe 5. The toothed belt 64 is wound between the two transmission gears 63; when the lifting plate 12 is lifted, the spray head 51 rotates toward the side of the spray pipe 5 close to the lifting plate 12, and when the lifting plate 12 is lowered, the spray head 51 rotates toward the side of the spray pipe 5 away from the lifting plate 12.

[0038] Reference Figure 3 , Figure 4 , Figure 5 A connecting arc groove 52 is provided on the outer peripheral wall of the spray pipe 5, and the connecting arc groove 52 is connected to the inside of the spray pipe 5. The connecting arc groove 52 is arranged in an arc shape around the central axis of the spray pipe 5. It should be noted that the connecting arc groove 52 is located in the mounting ring 14 (that is, the mounting ring 14 covers the connecting arc groove 52); the machine 1 is connected to a liquid inlet pipe 15 for supplying lubricant to the spray pipe 5, and the outlet end of the liquid inlet pipe 15 passes through the inner peripheral wall of the mounting ring 14. When the lifting plate 12 is lifted and lowered (that is, during the rotation of the spray pipe 5), the outlet end of the liquid inlet pipe 15 is connected to the connecting arc groove 52. When the lifting plate 12 is lifted to the highest position or lowered to the lowest position, a misalignment is formed between the outlet end of the liquid inlet pipe 15 and the connecting arc groove 52.

[0039] The implementation principle of Example 1 of the present application is as follows: the lifting plate 12 drives the first rotating rod 13 to rotate during the lifting process, thereby driving the spray pipe 5 to rotate a certain angle to expand the spraying range of the nozzle 51, so that the lubricant sprayed by the nozzle 51 acts on the surface of the punch 2 and the surface of the foam 8 respectively, and reduces the friction between the punch 2 and the hole wall of the foam 8 when the punch 2 is lifted off the foam 8 after the punch 2 completes the punching action on the foam 8, thereby reducing the possibility that the punch 2 will lift up the foam 8 when the punch 2 is lifted off, thereby improving the punching efficiency of the foam 8.

[0040] By connecting the arc groove and the mounting ring 14, the nozzle 51 can spray lubricant outward during the lifting or lowering process of the lifting plate 12 to lubricate the punch 2 and the foam 8; when the lifting plate 12 is lifted to the highest position or lowered to the lowest position, the outlet end of the liquid inlet pipe 15 and the connecting arc groove 52 are misaligned, thereby closing the liquid inlet pipe 15, stopping the supply of lubricant to the nozzle 51, and making the nozzle 51 automatically open and close, thereby improving the convenience of opening and closing the nozzle 51 and reducing the waste of lubricant.

[0041] Embodiment 2: The embodiment of the present application discloses a punching machine for cotton bale processing.

[0042] Reference Figure 6 , Figure 7 The punching machine for cotton bale processing disclosed in the embodiment of the present application is different from that in embodiment 1 in that: In this embodiment, a second rotating rod 16 is rotatably installed on the machine 1, and the first rotating rod 13 and the second rotating rod 16 are coaxially arranged; the conveying assembly 4 includes a conveying disc 41, a second gear 42, a second rack 43 and a linkage part, and the conveying disc 41 is slidably installed on the machine 1. The conveying disc 41 has an installation station 411 for installing the foam 8, and the foam 8 to be punched is placed in the installation station 411.

[0043] Reference Figure 6 , Figure 7 The second gear 42 is coaxially fixed to the outer peripheral wall of the second rotating rod 16 at one end away from the first rotating rod 13. A bracket 412 is fixedly installed on the side wall of the conveying disk 41. The second rack 43 is fixedly installed on the bracket 412. The second rack 43 is connected to the conveying disk 41 through the bracket 412. The second gear 42 and the second rack 43 are meshed for transmission; a linkage member is arranged between the first rotating rod 13 and the second rotating rod 16. When the lifting plate 12 is lifted, the linkage member causes the first rotating rod 13 and the second rotating rod 16 to be circumferentially linked (that is, the first rotating rod 13 and the second rotating rod 16 rotate synchronously), and the conveying disk 41 moves toward the punching station 11. When the lifting plate 12 is lowered, the first rotating rod 13 and the second rotating rod 16 are disengaged from each other.

[0044] Reference Figure 6 , Figure 8 In this embodiment, the linkage member includes a linkage sleeve 44, a ratchet 45, a pawl 46 and a torsion spring. The linkage sleeve 44 is coaxially fixed to one end of the first rotating rod 13 close to the second rotating rod 16, and one end of the second rotating rod 16 close to the first rotating rod 13 extends into the linkage sleeve 44. The ratchet 45 is coaxially fixed to one end of the second rotating rod 16 close to the first rotating rod 13. One end of the pawl 46 is hinged to the inner circumferential wall of the linkage sleeve 44. A torsion spring (not shown in the figure) is installed between the linkage sleeve 44 and the pawl 46. The torsion spring normally causes the pawl 46 to mesh with the ratchet 45.

[0045] The implementation principle of Example 2 of the present application is as follows: when the lifting plate 12 is lifted, the conveying disc 41 is displaced toward the punching station 11 under the action of the second gear 42 and the second rack 43, thereby conveying the foam 8 at the installation station 411 to the punching station 11 for punching; the lifting plate 12 is driven down, so that the punch 2 punches the foam 8. During this process, the linkage sleeve 44 is reversed, resulting in the pawl 46 being unable to push the ratchet 45 to rotate, thereby causing the first rotating rod 13 and the second rotating rod 16 to disengage from each other, so that the conveying disc 41 remains stationary; after one punching is completed, the lifting plate 12 is lifted off, and the conveying disc 41 can continue to displace for a period of time, so that the surface of the foam 8 can continue to be punched, and this is repeated, so that the surface of the foam 8 is covered with punching holes, so that the punch 2 punches the foam 8 once, the conveying disc 41 can convey the foam 8 for a distance, and the foam 8 and the punch 2 are sprayed with lubricant twice, which greatly improves the operational convenience of the overall structure.

[0046] Embodiment 3: The embodiment of the present application discloses a punching machine for cotton bale processing.

[0047] Reference Fig. 9 , Fig.10 The difference between the punching machine for cotton bale processing disclosed in the embodiment of the present application and the embodiment 2 is that: In this embodiment, a plurality of pawls 46 are arranged at intervals around the central axis of the linkage sleeve 44, and the number of torsion springs and pawls 46 is arranged correspondingly; the peripheral wall of the linkage sleeve 44 is provided with an unlocking groove 441 connected to the interior of the linkage sleeve 44, and the unlocking groove 441 is arranged correspondingly to the number of pawls 46; the linkage sleeve 44 is provided with an unlocking component 7, which is used to drive all pawls 46 to disengage from the ratchet 45 at the same time.

[0048] Reference Fig. 9 , Fig.10 The unlocking assembly 7 includes an unlocking ring 71 and a pull rod 72. The unlocking ring 71 is rotatably mounted on the outer peripheral wall of the linkage sleeve 44. The pull rod 72 is arranged corresponding to the number of the pawls 46. One end of the pull rod 72 is hinged to the corresponding pawl 46, and the other end passes through the corresponding unlocking groove 441 and is hinged to the inner peripheral wall of the unlocking ring 71.

[0049] Reference Fig. 9 A limit block 442 is fixedly installed on the outer wall of the linkage sleeve 44, and the limit block 442 is located on one side of the unlocking ring 71. A limit hole 443 is provided on the side wall of the limit block 442 close to the unlocking ring 71; a force rod 711 is slidably installed on the outer wall of the unlocking ring 71. When the unlocking ring 71 drives all the pawls 46 to disengage from the ratchet 45, the force rod 711 rotates to a state relative to the limit hole 443.

[0050] The implementation principle of Example 3 of the present application is as follows: by setting a plurality of pawls 46, the plurality of pawls 46 act on the ratchet 45 at the same time, so as to increase the force application point of the linkage sleeve 44 on the ratchet 45, thereby improving the stability of the overall structure and reducing the possibility of damage to the pawls 46; when the surface of the foam 8 is covered with punching holes (that is, after the entire foam 8 is punched), the unlocking ring 71 is driven to rotate around the central axis of the linkage sleeve 44, and the unlocking ring 71 pulls all the pawls 46 through a plurality of pull rods 72, forcing the pawls 46 to disengage from the ratchet 45, so that the first rotating rod 13 and the second rotating rod 16 can be separated from each other. At this time, the operator can retract the conveying disc 41 to restore the conveying disc 41 to its initial position and install the next foam 8, thereby improving the operational convenience of the overall structure.
