[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0034] For some cutting machines, a conveyor belt is set on the operating table, that is, the upper surface of the conveyor belt is used as the operating table. After cutting is completed, the conveyor belt can transfer the cut pieces together with the residual materials to one side for sorting by the staff. However, this is often prone to omissions, and on a piece of fabric, in order to fully utilize it, the cut pieces of different shapes are usually arranged in a comprehensive manner. After cutting is completed and transferred to one side by the conveyor belt, they will be mixed together, which is inconvenient to distinguish, thereby increasing the difficulty of sorting.

[0035] Combination Figure 1-Figure 14 , an automatic cutting machine for combat boots uppers, comprising a cutting table 10, a cutting mechanism, a film arrangement system, and a displacement gantry 11 on the upper side of the cutting table 10 for driving the cutting mechanism to move, the displacement gantry 11 being controlled by the film arrangement system, the cutting mechanism comprising a hydraulic cylinder 12, a docking seat 20 and a cutting and assembling mechanism 30, the docking seat 20 being assembled at the output end of the hydraulic cylinder 12, the cutting and assembling mechanism 30 being clamped at the lower side of the docking seat 20, the hydraulic cylinder 12 punches the docking seat 20 so that the cutting and assembling mechanism 30 cuts the fabric;

[0036] The assembly and cutting mechanism 30 includes an assembly panel 31 that is clamped with the docking seat 20. A cutter 32 for cutting fabrics is movably mounted on the inner side of the assembly panel 31. The cut pieces are clamped on the inner side of the cutter 32. When the next cut is made, the newly cut pieces push the pieces to move up on the inner side of the cutter 32. A material storage component 33 for receiving the pieces and clamping them is provided above the cutter 32. After the cutter 32 completes the cutting, the material storage component 33 is driven to move the pieces clamped on the inner side up in advance, so as to prepare for the next cutting by the cutter 32. The pieces are moved to the storage component 33 to make room for clamping. In this way, in each cutting, the newly cut pieces only need to overcome the pressure of the upper pieces and squeeze the upper pieces into the storage component 33 for clamping, and the pieces that have previously entered the storage component 33 will not form an obstacle to the newly entered pieces, nor will they affect the cutting function of the cutter 32. Therefore, through the cooperation of the cutter 32 and the storage component 33, the pieces can be collected at the same time while meeting the cutting needs, which greatly improves the work efficiency.

[0037] Furthermore, the lower surface of the docking seat 20 is provided with a positioning groove 21 for docking the assembly panel 31, and a material storage groove 22 for accommodating the cut pieces, a discharge push rod 23 is provided in the middle of the material storage groove 22, an electric clamp 24 is provided on the surface of the positioning groove 21, and a clamping block 311 corresponding to the electric clamp 24 is provided on the upper surface of the assembly panel 31, and the shape of the cutter 32 is the shape of the cut piece.

[0038] In shoemaking, according to a variety of different cut pieces, the cutters 32 are prefabricated in advance to cut the fabric into different cut pieces respectively, and the outer frame of the assembly panel 31 matched with the cutters 32 is of uniform specification so as to be uniformly docked with the positioning groove 21. The relative positions of different cutters 32 on the inner side of the assembly panel 31 are intersected, and the unloading push rod 23 is located above the intersection so that the cut pieces cut by different cutters 32 can be ejected from the storage groove 22 by the electric clamp 24;

[0039] By replacing different assembly panels 31 under the docking seat 20, the electric clamp 24 and the clamp block 311 complete the quick docking, so that different cutters 32 can cut the fabrics respectively, so as to cut different pieces;

[0040] Specifically, the arrangement of the pieces on the flat fabric is simulated through the arrangement system, and the cutting sequence is calculated in batches according to different pieces. Then, the displacement gantry 11 is controlled to drive the docking seat 20. After all the cutting of one piece is completed, a new assembly panel 31 is replaced to allow another cutter 32 to continue cutting. This process is carried out until all the fabrics are cut. By classifying the pieces cut by different cutters 32, the different pieces are automatically classified, which provides convenience for subsequent use.

[0041] Combination Figure 4-Figure 9 In the previous embodiment: the outer surface of the cutter 32 protrudes with an upper limit edge 321 and a lower limit edge 323, and the side surface of the upper limit edge 321 is fixedly connected with a tension spring A322 through a protruding block, and one end of the tension spring A322 is fixedly connected to the upper surface of the assembly panel 31;

[0042] A cutting hole 312 is provided at the center of the surface of the assembly panel 31, and an assembly frame 313 is welded to the edge of the cutting hole 312. The assembly frame 313 and the outer surface of the cutter 32 are adapted to each other, and the cutter 32 slides on the inside of the assembly frame 313. The upper limit edge 321 and the lower limit edge 323 are respectively located above and below the assembly frame 313. In the initial state, the tension spring A322 pulls the upper limit edge 321 to fit the upper surface of the assembly frame 313.

[0043] When the hydraulic cylinder 12 pushes the docking seat 20 to prompt the cutter 32 to cut the fabric, the process is as follows: first, the lower side of the cutter 32 abuts against the upper surface of the fabric, and as the hydraulic cylinder 12 continues to advance, the cutter 32 slides upward on the inner side of the assembly frame 313 until the lower surface of the assembly frame 313 abuts against the lower limit edge 323, and then as the hydraulic cylinder 12 continues to advance, the assembly frame 313 exerts force on the lower limit edge 323, prompting the cutter 32 to complete the cutting, and the cut pieces will be stuck on the inner side of the cutter 32, and then when the hydraulic cylinder 12 controls the docking seat 20 to move back, the tension spring A322 pulls the cutter 32 to restore its position; then in the next cutting, the new pieces entering the inner side of the cutter 32 will push the pieces remaining from the previous cutting to move upward.

[0044] Furthermore, the inner surface of the cutter 32 is composed of a friction portion 326 and a slope portion 327 from bottom to top. The height of the friction portion 326 is set to be 1-1.5 times the thickness of the cutting piece. The slope portion 327 is inclined toward the outside of the cutter 32. The lower side of the cutter 32 is a blade portion 328, which is inclined toward the outside of the cutter 32. The blade portion 328 corresponds to the edge position of the cutting piece size.

[0045] After the fabric is cut by the blade portion 328, the edge of the cut piece will be slightly larger than the inner diameter of the cutter 32 to ensure that the cut piece can be smoothly stuck inside the cutter 32. When the cut piece enters the cutter 32, the edge will rub against the friction portion 326, further ensuring that the cut piece will be stably stuck in the cutter 32 and will not fall off. The height of the friction portion 326 is set to the thickness of 1-1.5 pieces of the cut piece, so that when the cut piece is slightly compressed, its inner side can only fully accommodate one cut piece, so as to avoid multiple cut pieces remaining inside the cutter 32 at the same time, resulting in greater resistance when the cutter 32 is cutting. The cut piece pushed on the upper side will enter the inclined portion 327, where the cut piece will not be in force contact with the inner wall of the inclined portion 327.

[0046] It should be noted that when cutting genuine leather or leather fabric, it is necessary to pay attention to the location of the skin damage and avoid the skin damage during cutting. Therefore, this type of fabric will not be stacked and cut during cutting. Therefore, the height of the friction portion 326 is set to the thickness of 1-1.5 pieces of cutting pieces, which can be comprehensively applied to a variety of genuine leather or leather fabrics of different thicknesses. The thickness range of the genuine leather or leather fabric is between 0.6mm-0.8mm, and it has toughness and can be clamped on the inside of the cutter 32.

[0047] Combination Figure 10-11In the previous embodiment: a plurality of material storage components 33 are arranged along the path direction of the assembly frame 313, and the cutter 32 is provided with an assembly groove 324 at a position corresponding to the material storage component 33, and the lower surface of the assembly groove 324 corresponds to the junction of the friction portion 326 and the inclined portion 327, so that when the cut piece enters the inner side of the inclined portion 327 from the inner side of the friction portion 326, it can directly enter the clamping range of the material storage component 33, and be flexibly clamped by the plurality of material storage components 33;

[0048] The material storage component 33 includes a support frame 331 and a flexible rubber ring 332 that is movable on the surface. A driving shaft 333 that drives the flexible rubber ring 332 to move on the surface of the support frame 331 is provided on the upper side of the support frame 331. The flexible rubber ring 332 has a thickness and one side protrudes from the side surface of the support frame 331, so that the cut pieces entering the range of the support frame 331 are clamped by the outer surface of the flexible rubber ring 332, wherein the surface of the outer side of the rubber ring 332 for clamping the cut pieces is roughened to increase the friction with the edge of the cut pieces, and when the flexible rubber ring 332 moves on the surface of the support frame 331, it can drive the clamped cut pieces to move upward, and one end of the driving shaft 333 is connected to a one-way wheel 334 (the one-way wheel 334 is equivalent to the flywheel in the prior art, and the specific internal structure is not repeated), and the support frame 331 is arranged on the inner side of the assembly groove 324, and when the cutter 32 moves to the highest position, the lower surface of the support frame 331 can abut against the lower surface of the assembly groove 324. Fig.14 As shown, the outer ring of the one-way wheel 334 is provided with teeth, and the inner ring is connected to the transmission belt 3341 through a pulley coaxially fixedly connected on one side, and the upper limit edge 321 is fixedly equipped with a rack 325 meshing with the teeth of the outer ring of the one-way wheel 334. Fig.10 , Fig.11 As shown, the one-way wheel 334 drives the inner ring to rotate only when rotating counterclockwise, and further drives the driving shaft 333 to rotate through the transmission belt 3341, so that the flexible rubber ring 332 is used to hold the surface of one side of the cut piece and moves from bottom to top, thereby moving the cut piece from bottom to top;

[0049] Furthermore, during the cutting process, the cutter 32 is against the fabric and before the cutting is completed, the reverse pressure of the fabric causes the cutter 32 to move upward. As the rack 325 moves upward, it only pushes the outer ring of the one-way wheel 334 to rotate clockwise. As the cutting is completed, the tension spring A322 pushes the cutter 32 to restore its position, and the rack 325 moves downward, thereby driving the one-way wheel 334 to rotate counterclockwise, thereby prompting the flexible rubber ring 332 used to hold the surface of one side of the cut piece to move from bottom to top, prompting the cut piece held on the surface of the flexible rubber ring 332 to automatically move upward, exposing space below, so that the cut piece inside the cutter 32 can enter smoothly, and the cut piece originally held on the inner side of the flexible rubber ring 332 will not form an obstacle to the newly entered cut piece, nor will it increase the resistance to be overcome by the cutter 32 when cutting.

[0050] Combination Figure 10-Figure 14 In the previous embodiment: a surface of the support frame 331 close to the clamping piece is provided with an anti-falling component 335 for preventing the piece from falling, and a gap of one piece is left between the anti-falling component 335 and the lower surface of the support frame 331;

[0051] The anti-falling component 335 includes a wedge block 3351 movably embedded in the surface of the support frame 331, a matching groove 3352 is provided inside the wedge block 3351, a matching rod 3353 is installed in the matching groove 3352, and the vertically movable matching rod 3353 is used to push the wedge block 3351 to move and protrude from the side surface of the support frame 331. The upper end of the matching rod 3353 is sleeved with a push spring B3354, and the lower end of the matching rod 3353 normally protrudes from the lower surface of the support frame 331. Fig.13 , Fig.14 As shown in the figure, when the lower side of the support frame 331 is pressed and fitted with the lower side of the assembly groove 324, the matching rod 3353 is also squeezed into the inner side of the support frame 331, causing the wedge block 3351 to protrude from the side surface of the support frame 331. Therefore, when the cutter 32 is cutting the fabric, the downward impact force generated by the cutting causes the cut piece held between the flexible rubber ring 332 to slide downward. The cut piece will be limited by the wedge block 3351 protruding from the side surface of the support frame 331, thereby preventing it from continuing to slide down. In addition, the impact force and the wedge block 335 1, and can also compact the multiple cut pieces held between the flexible rubber rings 332 to make them fit tightly, so that the multiple cut pieces can be fully stored between the flexible rubber rings 332; a cut piece spacing is set between the anti-fall component 335 and the lower surface of the support frame 331, so that when the wedge block 3351 protrudes, there is still a space for holding the cut pieces under the wedge block 3351, and the cut piece entered by the cutter 32 can be smoothly held, and then driven by the flexible rubber ring 332 to move to the top of the wedge block 3351.

[0052] Combination Figure 1 In the previous embodiment: a material discharge trough 13 for discharging materials is provided on the surface of the cutting table 10, and a pull-out plate 14 which is electrically controlled to move is provided below the material discharge trough 13.

[0053] By placing a receiving frame on the pull-out plate 14, when the displacement gantry 11 drives the cutting mechanism to perform cutting, when the number of cut pieces held on the material storage component 33 reaches the maximum, the displacement gantry 11 can be controlled to move the docking seat 20 to above the material discharge trough 13, and the cut pieces between the material storage components 33 are pushed down by the unloading push rod 23, so that they pass through the material discharge trough 13 and fall into the corresponding receiving frame above the pull-out plate 14; by placing different receiving frames on the pull-out plate 14 and controlling the movement of the pull-out plate 14 so that different receiving frames are located below the material discharge trough 13, different cut pieces can be stored in a classified manner.

[0054] Working principle: The arrangement system simulates the arrangement of the flat fabric, and calculates the cutting sequence according to different pieces. Then the displacement gantry 11 is controlled to drive the docking seat 20, so that the cutter 32 cuts the pieces in a centralized manner. The cut pieces can be temporarily stored in multiple storage components 33. Among them, the newly cut pieces overcome the pressure of the upper pieces and squeeze them into the storage components 33 for clamping. At the same time, the storage components 33 will automatically move the clamped pieces themselves upward, so that the newly entered pieces will not be blocked, and will not affect the cutting function of the cutter 32. The cutting knife 32 and the material storage assembly 33 cooperate to collect the cut pieces at the same time while satisfying the cutting. When the cut pieces held on the material storage assembly 33 reach the maximum amount, the displacement gantry 11 is controlled to move the docking seat 20 to the top of the material discharge trough 13, and the unloading push rod 23 is controlled to push the cut pieces between the material storage assembly 33 down and make them fall into the receiving frame above the pull-out plate 14. After one kind of cut pieces are all cut, another assembly panel 31 is quickly replaced to make another kind of cutting knife 32 continue cutting, and this process is carried out until all the fabrics are cut.

[0055] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
