[0035] In use, the carpet raw material to be punched is stacked in the storage bin 11 of the front end feeding mechanism 1, the carpet raw material is grabbed from the storage bin 11 by the transfer gripper 12, placed on the upper surface of the conveying mechanism 2, and the conveying mechanism 2 continues to convey the carpet raw material into the press flat mechanism 3 inside, since the press flat mechanism 3 is arranged in the preheating treatment mechanism 4 inside, the both ends of the support transmission mechanism 31 are penetrated out of the preheating treatment mechanism 4, so that the carpet raw material enters the press flat mechanism 3 inside and is pressed by the press roller 321 along the conveying direction of the carpet raw material, the edge position of each carpet raw material falls behind the central position of the carpet raw material, which can press the carpet from the central position to the edge position, gradually flatten and loosen the carpet from the central position to the edge position, avoid the wrinkles of the edge of the carpet caused by the conventional press structure, and avoid the error of the thickness of the carpet caused by the stretching of the tension of the edge of the carpet.

[0036] Since the passive flattening mechanism 32 includes several pressing roller groups, the distance between two adjacent pressing roller groups in the carpet raw material conveying direction inside the preheating treatment mechanism 4 is gradually reduced, and each pressing roller 321 is staggered with each other, and the angle between each pressing roller 321 and the conveying direction of the carpet raw material is equal, so that when the carpet raw material is driven by the supporting conveying mechanism 31 to pass through each pressing roller 321, the edge position of each section of the carpet raw material lags behind the central position of the carpet raw material in the conveying direction of the carpet raw material, and is gradually pressed by the multiple pressing rollers 321, and as the time inside the preheating treatment mechanism 4 is prolonged, the carpet is heated more fully, the pressing time interval of the carpet by the multiple pressing rollers 321 is shorter, the softening effect of the central adhesive layer of the carpet is better, and the pressing effect of the carpet by the multiple pressing rollers 321 is better, so that the thickness of the central position and the edge position of the carpet can be effectively guaranteed to be consistent by the pressing of each pressing roller 321 during the later punching of the carpet raw material, and the uniformity of the punched carpet is effectively improved.

[0037] Further, please refer to Figure 5 、 Figure 7 , the supporting conveying mechanism 31 includes a conveying belt 311 and a supporting pad 312, the supporting pad 312 is arranged inside the conveying belt 311, and the supporting pad 312 is used to limit the vertical movement of the upper surface of the conveying belt 311.

[0038] The supporting conveying mechanism 31 is provided with a mounting plate 33 outside, the pressing roller 321 includes a positioning shaft 3211 and a movable sleeve shaft 3212, the movable sleeve shaft 3212 is rotatably sleeved outside the positioning shaft 3211, and the positioning shaft 3211 is fixed between the mounting plate 33; when the carpet raw material passes through the pressing roller 321, the movable sleeve shaft 3212 is supported by the positioning shaft 3211, and the conveying belt 311 is supported by the supporting pad 312, which jointly presses and flattens the carpet raw material.

[0039] Thus, in use, when the carpet raw material passes through the pressing roller 321, the movable sleeve shaft 3212 is supported by the positioning shaft 3211, and the conveying belt 311 is supported by the supporting pad 312, which jointly presses and flattens the carpet raw material, and the carpet raw material can drive the movable sleeve shaft 3212 to rotate, so that the carpet raw material can be effectively pressed and flattened while continuing to be conveyed through the pressing roller 321.

[0040] Further, please refer to Figures 1-3 、 Figure 8The fixed die 6 is internally provided with a fixed cavity 61, and the upper surface of the fixed die 6 is provided with a positioning plate 62 outside the fixed cavity 61. The surface of the positioning plate 62 is uniformly provided with a plurality of positioning pins 63. The positioning pins 63 can penetrate the carpet raw material. The plurality of positioning pins 63 can penetrate the carpet raw material together to fix the carpet raw material at the cutting position, so as to accurately position the carpet raw material, effectively ensure the stability of the carpet cutting in the later stage, and prevent the carpet from slipping to cause cutting misplacement.

[0041] The positioning mechanism 5 includes two symmetrical telescopic guide rods 51. The telescopic guide rods 51 can be telescopic. After the carpet raw material is guided to the end of the fixed die 6 away from the preheating treatment mechanism 4, the telescopic guide rods 51 are retracted to lay the carpet raw material on the surface of the fixed die 6. In use, the carpet raw material laid on the surface of the fixed die 6 can be pressed to the plurality of positioning pins 63 penetrating the carpet raw material together by manual method, or the carpet raw material laid on the surface of the fixed die 6 can be pressed to the plurality of positioning pins 63 penetrating the carpet raw material together by mechanical rod pressing method, so as to fix the carpet raw material at the position limited by the plurality of positioning pins 63.

[0042] The cutting movable die 7 is driven and moved by the cutting driving mechanism 8. One side of the cutting movable die 7 close to the fixed die 6 is provided with a movable cavity 71. The fixed cavity 61 and the movable cavity 71 can be combined to cut and form the carpet raw material at the cutting position. The power output of the cutting driving mechanism 8 is controlled by two button switches. Only when the two button switches are pressed at the same time and continuously, the cutting driving mechanism 8 can output power to drive the cutting movable die 7 to move downward, so as to drive the movable cavity 71 to combine with the fixed cavity 61 to cut and form the carpet raw material according to the shape limited by the fixed cavity 61 and the movable cavity 71.

[0043] Further, referring to Figures 6-7 The preheating treatment mechanism 4 includes a heat preservation shell 41. The inside top of the heat preservation shell 41 is provided with a heating wire 42. The inside of the heat preservation shell 41 and below the heating wire 42 is provided with a flow guide fan 43. The flow guide fan 43 is used to stir the air inside the heat preservation shell 41 to preheat the carpet raw material passing through the inside of the heat preservation shell 41 under the driving of the supporting conveying mechanism 31. Thus, the air inside the heat preservation shell 41 is fully stirred by the flow guide fan 43 to effectively ensure the heating effect of the heating wire 42 on the inside of the heat preservation shell 41 and the uniformity of the heating of the carpet raw material, so that the carpet can be fully heated inside the preheating treatment mechanism 4, and the thickness of the central position and the edge position of the carpet is consistent when the carpet raw material is cut in the later stage through the pressing of the various pressing rollers 321.

[0044] Further, referring to Figures 1-4, the storage bin 11 includes a storage table 111 for storing the carpet raw material and a lifting guide rail 112 fixed between the driving block of the lifting guide rail 112 and the storage table 111, and the lifting guide rail 112 can drive the storage table 111 to lift by a distance of the thickness of the carpet raw material after the transfer clamp jaw 12 takes the carpet raw material each time.

[0045] The transfer clamp jaw 12 includes a horizontal driving guide rail 121, a connecting frame 122, and a plurality of suction cups 123, the plurality of suction cups 123 are uniformly fixed at the bottom end of the connecting frame 122, and the top end of the connecting frame 122 is fixed between the driving block of the horizontal driving guide rail 121; the suction cup 123 is a vacuum suction cup, and the cooperation of each suction cup 123 can take the carpet raw material from the storage table 111, and the horizontal driving guide rail 121 can drive the connecting frame 122 to move each suction cup 123 to place the carpet raw material on the upper surface of the conveying mechanism 2.

[0046] Therefore, in use, the cooperation of each suction cup 123 of the transfer clamp jaw 12 can take the carpet raw material from the storage table 111, and after taking the carpet raw material each time, the storage table 111 is lifted by a distance of the thickness of the carpet raw material, the carpet raw material stored on the storage table 111 is conveyed upward by a certain distance to provide the height of the carpet raw material grabbed by each suction cup 123 of the transfer clamp jaw 12 next time, so that each suction cup 123 of the transfer clamp jaw 12 can take the next carpet raw material, and the horizontal driving guide rail 121 drives the connecting frame 122 to move each suction cup 123 to place the carpet raw material on the upper surface of the conveying mechanism 2, and continuously convey the carpet raw material.

[0047] Further, the conveying surface of the conveying mechanism 2 is a rough surface, and the conveying surface of the conveying mechanism 2 and the carpet raw material have a friction force that can drive the carpet raw material to move, thereby effectively conveying the carpet raw material.

[0048] Working principle:

[0049] In use, the carpet raw material to be punched is stacked on the storage table 111 of the storage bin 11 of the front end feeding mechanism 1, each suction cup 123 of the transfer clamp jaw 12 cooperates to take the carpet raw material from the storage table 111, and then the horizontal driving guide rail 121 can drive the connecting frame 122 to move each suction cup 123, when passing through the upper surface of the conveying mechanism 2, each suction cup 123 releases the suction force to place the carpet raw material on the upper surface of the conveying mechanism 2, at this time, the lifting guide rail 112 drives the storage table 111 to lift by a distance of the thickness of the carpet raw material, and the carpet raw material stored on the storage table 111 is conveyed upward by a certain distance to provide the height of the carpet raw material grabbed by each suction cup 123 of the transfer clamp jaw 12 next time, so that each suction cup 123 of the transfer clamp jaw 12 can take the next carpet raw material, and continuously convey the carpet raw material;

[0050] Since the conveying surface of the conveying mechanism 2 has friction with the carpet raw material that can drive the carpet raw material to move, the carpet raw material can be effectively conveyed into the pressing and flattening mechanism 3;

[0051] Since the pressing and flattening mechanism 3 is arranged in the preheating treatment mechanism 4, the supporting conveying mechanism 31 penetrates out of the preheating treatment mechanism 4 at both ends, so that the carpet raw material enters the pressing and flattening mechanism 3, and under the preheating treatment of the preheating treatment mechanism 4, when the carpet raw material passes through the pressing roller 321, the movable sleeve shaft 3212 is supported by the positioning shaft 3211, and the conveyor belt 311 is supported by the supporting pad 312, which jointly press and flatten the carpet raw material. Through the restriction in the upward and downward directions, and through the rotation of the movable sleeve shaft 3212, the pressure for pressing and flattening the carpet raw material can be effectively provided, and at the same time, the carpet raw material can drive the movable sleeve shaft 3212 to rotate, so that the carpet raw material can be effectively conveyed through the pressing roller 321 while being pressed and flattened;

[0052] At this time, along the conveying direction of the carpet raw material, the edge position of each section of the carpet raw material lags behind the central position of the carpet raw material and is pressed by the pressing roller 321, which can sequentially press from the central position to the edge position of the carpet raw material, and gradually flatten and loosen the carpet from the central position to the edge position. The edge curling of the carpet caused by the inherent tension of the edge to the center can be loosened, thereby effectively avoiding the wrinkles caused by the compaction of the edge curling caused by the conventional structure for removing the curling, and the uneven edge layer thickness caused by the stretching tension caused by the compaction, and avoiding the thickness error of the carpet in the later processing;

[0053] Since the passive flattening mechanism 32 includes a plurality of pressing roller groups, the spacing between the adjacent two pressing roller groups gradually decreases along the conveying direction of the carpet raw material in the preheating treatment mechanism 4, and each pressing roller 321 is arranged in an interlaced manner between two pressing rollers 321, and the included angle between each pressing roller 321 and the conveying direction of the carpet raw material is equal. Therefore, when the carpet raw material is driven by the supporting conveying mechanism 31 to pass through each pressing roller 321, along the conveying direction of the carpet raw material, the edge position of each section of the carpet raw material lags behind the central position of the carpet raw material and is gradually pressed by the plurality of pressing rollers 321, and as the time in the preheating treatment mechanism 4 is prolonged, the heating of the carpet is more sufficient, the pressing time interval of the carpet by the plurality of pressing rollers 321 is shorter, the softening effect of the glue layer in the center of the carpet is better, and the pressing effect of the carpet by the plurality of pressing rollers 321 is better when the pressing time interval is shorter. Therefore, it can be effectively guaranteed that the thickness of the central position and the edge position of the carpet is consistent after the carpet raw material is punched, and the uniformity of the punched carpet is effectively improved;

[0054] Inside the preheating mechanism 4, the air guide fan 43 is used to stir the air inside the heat preservation shell 41, and preheat the carpet raw material supported by the conveying mechanism 31 inside the heat preservation shell 41. The driving of the conveying mechanism 31 preheats the carpet raw material inside the heat preservation shell 41, so that the air inside the heat preservation shell 41 is fully stirred by the air guide fan 43, which ensures the heating effect of the heating wire 42 inside the heat preservation shell 41, and effectively ensures the uniformity of the heating of the carpet raw material, so that the carpet can be fully heated inside the preheating mechanism 4, and the thickness of the carpet at the central position and the edge position is consistent when the carpet raw material is punched later by the pressing of each pressing roller 321;

[0055] The carpet raw material output from the preheating mechanism 4 is continuously conveyed to the fully extended telescopic guide rod 51, which is retracted after guiding the carpet raw material out of the cutting fixed die 6 away from the preheating mechanism 4, and lays the carpet raw material on the surface of the cutting fixed die 6. The carpet raw material laid on the surface of the cutting fixed die 6 is pressed down to the plurality of positioning needles 63 by manual method, and the carpet raw material is fixed at the position limited by the plurality of positioning needles 63.

[0056] After the positioning of the carpet raw material is completed, the power output of the cutting driving mechanism 8 is controlled by two button switches. Only when the two button switches are pressed at the same time and continuously, the cutting driving mechanism 8 can output power to drive the cutting movable die 7 to move downward, so as to drive the mold closing between the movable cavity 71 and the fixed cavity 61, and cut and form the carpet raw material according to the shape limited by the fixed cavity 61 and the movable cavity 71. Then the cut and formed carpet is taken out of the fixed cavity 61, and the cutting of the carpet raw material is completed. The cutting movable die 7 and the cutting fixed die 6 are sequentially used to cut and form the next carpet raw material.

[0057] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
