Description

Technical Field

[0001] The present invention relates to the technical field of cloth cutting machines, and specifically to a vertical cloth cutting machine with high cutting accuracy. Background Art

[0002] A vertical cloth cutting machine is an automated cutting device designed specifically for industries such as textiles, clothing, and leather. Due to the low technical content and single function of traditional cutting equipment, which relies on manual operation, the production efficiency is low and the cutting accuracy is poor, thus unable to meet the market demand. The emergence of the vertical cloth cutting machine has solved problems such as low efficiency, poor accuracy, and dependence on manual labor in traditional cutting techniques, promoted the automation upgrade of industries such as clothing and leather, and improved the production efficiency and product quality.

[0003] Patent Publication No. CN220619577U discloses a vertical cloth cutting machine, which relates to the technical field of cloth cutting machines, including a main body module and a cloth cutting module. The main body module includes a bottom plate, between the two sides of which a first n-shaped block and a second n-shaped block are fixedly connected. In the middle of both sides of the bottom plate, fixing columns are fixedly connected. The cloth cutting module is arranged between the first n-shaped block, the second n-shaped block, and the two fixing columns. The cloth cutting module includes a first flattening component arranged on the first n-shaped block, and second flattening components are arranged on both fixing columns. Lifting components are arranged on the tops of both fixing columns, and the two lifting components are respectively connected to the two second flattening components. Although it realizes that the first flattening component and the second flattening component can flatten the cloth over a large area, through the setting of the lifting component, it can drive the second flattening component to lift and adjust the height, and through the setting of the cloth cutting component, it can cut the cloth. However, this device uses a single cutting knife to cut the cloth. When cutting thicker or multiple layers of cloth, the blade needs to bear a large resistance, which easily leads to increased blade wear and even jamming, affecting the cutting accuracy, causing the blade to have a slight deviation during high-speed movement, resulting in cutting errors, and further reducing the cutting accuracy. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The motor drives the rotating shaft to rotate continuously, causing the semi-gear eight to rotate several times to convey the material, and then the semi-gear eight stops to stop the material conveyance. At this time, the gear disk drives the semi-gear nine to rotate, causing the upper cutter body and the lower cutter body to cut. After the cutting is completed, the semi-gear nine stops, and the semi-gear eight continues to rotate, thus circulating repeatedly to convey the material to a certain length and stop, and then the upper cutter body and the lower cutter body cut, and then the material continues to be conveyed, so that when the material is cut, the material does not move, thereby making the cutting of the material more accurate, and only a single motor can complete the conveyance and cutting of complex materials, making the device more flexible and convenient, reducing the use of power sources, and reducing energy consumption and costs.

[0017] 2. The rotation of the rotating shaft drives the reciprocating rod five to rotate through a pair of gears seven. The rotation of the reciprocating rod five drives the reciprocating plate to move reciprocally. Since the reciprocating plate is limited by the limiting plate, the reciprocating plate can only move reciprocally and cannot rotate. The reciprocating movement of the reciprocating plate drives the flattening roller one to move through the guiding rod and the connecting shell one. When the material is conveyed and cut, the movement of the flattening roller one can flatten the wrinkles or unevenness on the material, so that the material can be cut more accurately and errors are not likely to occur.

Detailed implementation manner

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1:

[0031] Please refer to Figure 1 - Figure 9As shown in the figure, a vertical cloth cutting machine with high cutting precision includes a workbench 1, a double-knife cutting mechanism, a driving mechanism, and a material conveying mechanism; a support column 2 is fixedly connected to the top end of the outer wall of the workbench 1; the double-knife cutting mechanism includes an upper knife body 3; the outer wall of the upper knife body 3 is slidably connected to the inner wall of the support column 2; a first through groove 4 is opened on one side of the outer wall of the support column 2; a slide plate 5 is fixedly connected to one side of the outer wall of the upper knife body 3; the outer wall of the slide plate 5 is slidably connected to the inner wall of the first through groove 4; a fixing plate 6 is fixedly connected to one side of the outer wall of the support column 2; a first reciprocating rod 7 is rotatably connected to the top end of the outer wall of the fixing plate 6, and the bottom end of the outer wall of the first reciprocating rod 7 penetrates through the fixing plate 6 and the slide plate 5; the first reciprocating rod 7 and the slide plate 5 are matched; the first reciprocating rod 7 rotates through the driving mechanism; a cutting groove 8 is opened on the top end of the outer wall of the workbench 1; a second through groove 9 is opened on one side of the outer wall of the support column 2; a first rack 10 is fixedly connected to one side of the outer wall of the upper knife body 3 through a first connecting block, and the first connecting block is located in the second through groove 9; a first gear 11 is rotatably connected to one side of the outer wall of the support column 2 through a first round rod; a square plate 12 is fixedly connected to the bottom end of the outer wall of the workbench 1; a lower knife body 13 is slidably connected to one side of the outer wall of the square plate 12; a second rack 14 is fixedly connected to one side of the outer wall of the lower knife body 13 through a first connecting rod; both the second rack 14 and the first rack 10 are meshed with the first gear 11; a third through groove 15 is opened at the bottom end of the outer wall of the workbench 1, and the third through groove 15 is communicated with the cutting groove 8; the third through groove 15 is matched with the lower knife body 13. By driving the first reciprocating rod 7 to rotate through the driving mechanism, the rotation of the first reciprocating rod 7 drives the slide plate 5 to reciprocate up and down, the slide plate 5 drives the upper knife body 3 to reciprocate. When the upper knife body 3 reciprocates, the upper knife body 3 drives the first rack 10 to move up and down through the first connecting block. Since both the second rack 14 and the first rack 10 are meshed with the first gear 11, the movement of the first rack 10 drives the first gear 11 to rotate, the rotation of the first gear 11 drives the second rack 14 to move up and down, and the up and down movement direction is opposite to that of the first rack 10. When the upper knife body 3 descends, the lower knife body 13 ascends. At this time, the upper knife body 3 cuts above the material, and the lower knife body 13 cuts below the material through the third through groove 15 and the cutting groove 8, making the cutting of the material more convenient. And because the upper and lower blades share the cutting force, the force on a single blade is reduced, the wear is reduced, and the cutting process is smoother. This not only prolongs the service life of the blade, but also reduces the cutting error caused by blade jamming, making the cutting precision of the upper knife body 3 and the lower knife body 13 synchronously cutting from the top and bottom of the cloth higher, and the upper knife body 3 and the lower knife body 13 synchronously cut into from the top and bottom of the cloth, and the upper and lower blades are ensured to completely coincide through a precise alignment system. The cloth is clamped during the cutting process, the force is evenly distributed, effectively suppressing the lateral displacement and local stretching, and significantly improving the flatness of the cutting edge.

[0032] The driving mechanism includes a motor 16; one side of the outer wall of the workbench 1 is fixedly connected with a fixed block 17 through a second connecting rod; the outer side wall of the motor 16 is arranged on the inner side wall of the fixed block 17; the output end of the motor 16 is provided with a rotating shaft 18; the top end of the outer wall of the first reciprocating rod 7 is fixedly connected with a second gear 19; the top end of the outer wall of the fixed plate 6 is rotatably connected with a rotating rod 20; the outer side wall of the rotating rod 20 is fixedly connected with a third gear 21, and the third gear 21 meshes with the second gear 19, and the radius of the third gear 21 is greater than the radius of the second gear 19; the top end of the outer wall of the rotating rod 20 is fixedly connected with a ninth half gear 22; the top end of the outer wall of the ninth half gear 22 is fixedly connected with a first reset rod 23; the top end of the outer wall of the fixed plate 6 is rotatably connected with a first rotating rod 24 through a connecting plate; one end of the outer wall of the first rotating rod 24 is fixedly connected with a gear disc 25; a set of first gear grooves 26 are formed on one side of the outer wall of the gear disc 25, and the set of first gear grooves 26 are arc-shaped; the first gear grooves 26 and the gear disc 25 are both matched with the ninth half gear 22; one side of the outer wall of the gear disc 25 is hinged with a first reset plate 27, and the first reset plate 27 is matched with the first reset rod 23; the other end of the outer wall of the first rotating rod 24 and the outer side wall of the rotating shaft 18 are both fixedly connected with a first sprocket 28, and a pair of first sprockets 28 are connected by a first chain 29. The motor 16 drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the first rotating rod 24 to rotate through the first sprocket 28 and the first chain 29. The first rotating rod 24 drives the gear disc 25 to rotate. When the first gear grooves 26 on the gear disc 25 are about to encounter the ninth half gear 22, the hinged first reset plate 27 will contact the first reset rod 23. At this time, the first reset plate 27 changes its angle and exerts a squeezing force on the first reset rod 23. The first reset rod 23 transmits the force to the ninth half gear 22. When the ninth half gear 22 encounters the first gear grooves 26, under the action of the force, the teeth of the ninth half gear 22 will be stuck into the first gear grooves 26. At this time, the rotation of the gear disc 25 drives the ninth half gear 22 to rotate. When the ninth half gear 22 rotates most of a circle, the two outer teeth of the ninth half gear 22 will abut against the plane of the gear disc 25. At this time, when the gear disc 25 rotates, the ninth half gear 22 is stuck in position and will not rotate until it encounters the first gear grooves 26 before it will rotate, causing the ninth half gear to stop after rotating most of a circle and being stuck at the same time. The rotation of the ninth half gear 22 drives the rotating rod 20 to rotate. The rotating rod 20 drives the third gear 21 to rotate. The third gear 21 drives the second gear 19 to rotate. The second gear 19 drives the first reciprocating rod 7 to rotate. Because the radius of the third gear 21 is greater than the radius of the second gear 19, the third gear 21 rotates most of a circle, while the second gear 19 and the first reciprocating rod 7 rotate several circles, causing the rotation of the first reciprocating rod 7 to first move the upper tool body 3 downward for cutting and then rise and reset to complete the material cutting operation.

[0033] The material conveying mechanism includes a conveying roller 30; a pair of conveying grooves 31 are opened at the top end of the outer wall of the workbench 1; one ends of the outer walls of the pair of conveying rollers 30 are respectively rotatably connected to one sides of the inner walls of the pair of conveying grooves 31; one ends of the outer walls of the pair of conveying rollers 30 are respectively fixedly connected with a third rotating rod 32 and a fourth rotating rod 33, and the third rotating rod 32 and the fourth rotating rod 33 both penetrate through the workbench 1; second sprockets 34 are fixedly connected to the outer side walls of the ends of the third rotating rod 32 and the fourth rotating rod 33 located outside the workbench 1, and the pair of second sprockets 34 are connected by a second chain 35; a semi-gear eight 36 is fixedly connected to one end of the outer wall of the third rotating rod 32; a third reset rod 37 is fixedly connected to one end of the outer wall of the semi-gear eight 36; a disc 38 is fixedly connected to the outer side wall of the rotating shaft 18; a set of third gear grooves 39 are opened on the outer side wall of the disc 38, and the set of third gear grooves 39 are arc-shaped; the third gear grooves 39 and the disc 38 are both matched with the semi-gear eight 36; a set of hinge blocks 40 are fixedly connected to one end of the outer wall of the disc 38;On one side of the outer wall of a group of hinged blocks 40, a third reset plate 41 is hinged, and a group of third reset plates 41 are all matched with a third reset rod 37. The motor 16 drives the rotating shaft 18 to rotate, so that the rotating shaft 18 drives the disc 38 to rotate, and the disc 38 drives the eighth half gear 36 to rotate through the third gear slot 39. The eighth half gear 36 drives the third rotating rod 32 to rotate, and the third rotating rod 32 drives the fourth rotating rod 33 to rotate through the second sprocket 34 and the second chain 35, thereby driving a pair of conveying rollers 30 to rotate. The rotation of the pair of conveying rollers 30 drives the material to be conveyed to the upper tool body 3 and the lower tool body 13 for cutting. When the disc 38 drives the eighth half gear 36 to rotate, the third reset plate 41 will first encounter the third reset rod 37 and apply pressure to the third reset rod 37. The third reset rod 37 transmits the pressure to the eighth half gear 36. When the eighth half gear 36 encounters the third gear slot 39, the teeth of the eighth half gear 36 are engaged in the third gear slot 39, so that the disc 38 drives the eighth half gear 36 to rotate. When the eighth half gear 36 rotates to a place without teeth, another third reset plate 41 will contact the third reset rod 37 again, causing the eighth half gear 36 to rotate until the eighth half gear 36 rotates to a position where the disc 38 has no third gear slot 39. At this time, the two outer teeth of the eighth half gear 36 are stuck by the outer wall of the disc 38 and cannot rotate until it encounters the third gear slot 39 again, enabling the double-knife cutting mechanism, the driving mechanism, and the material conveying mechanism to cooperate with each other. The motor 16 drives the rotating shaft 18 to rotate continuously, causing the eighth half gear 36 to rotate several times to convey the material, and then the eighth half gear 36 stops to stop the material conveying. At this time, the gear disc 25 drives the ninth half gear 22 to rotate, causing the upper tool body 3 and the lower tool body 13 to cut. After the cutting is completed, the ninth half gear 22 stops and the eighth half gear 36 continues to rotate, thus repeating the cycle to convey the material to a certain length and stop, and then the upper tool body 3 and the lower tool body 13 cut, and then the material continues to be conveyed. When the material is cut, the material does not move, so that when the material is cut, the accuracy is higher, and only a single motor 16 can complete the conveying and cutting of complex materials, making the device more flexible and convenient, reducing the use of power sources, and reducing energy consumption and costs.;

[0034] On one side of the outer wall of the workbench 1, an auxiliary plate 49 is fixedly connected; on one side of the outer wall of the auxiliary plate 49, a reciprocating rod five 50 is rotatably connected; on one end of the outer wall of the reciprocating rod five 50 and on the outer side wall of the rotating shaft 18, a gear seven 51 is fixedly connected, and a pair of gears seven 51 mesh with each other; on one side of the outer wall of the auxiliary plate 49, a limiting plate 52 is fixedly connected; on the outer side wall of the reciprocating rod five 50, a reciprocating plate 53 is arranged, and the top end of the outer wall of the reciprocating plate 53 is slidably connected to the bottom end of the outer wall of the limiting plate 52; at the bottom end of the outer wall of the reciprocating plate 53, a connecting shell one 55 is provided through a guiding rod 54; on the inner side wall of the connecting shell one 55, a flattening roller one 56 is arranged. When the rotating shaft 18 rotates, the rotation of the rotating shaft 18 drives the reciprocating rod five 50 to rotate through a pair of gears seven 51. The rotation of the reciprocating rod five 50 drives the reciprocating plate 53 to reciprocate. Since the reciprocating plate 53 is limited by the limiting plate 52, the reciprocating plate 53 can only reciprocate and cannot rotate. The reciprocating motion of the reciprocating plate 53 drives the flattening roller one 56 to move through the guiding rod 54 and the connecting shell one 55. When the material is conveyed and cut, the movement of the flattening roller one 56 can flatten the wrinkles or unevenness on the material, so that the material can be cut more accurately and errors are not likely to occur.

[0035] On one side of the outer wall of the workbench 1, a pair of vertical plates 42 are fixedly connected; on one side of the outer wall of the pair of vertical plates 42, adjusting blocks 43 are respectively arranged; at the bottom ends of the outer walls of the pair of adjusting blocks 43, sliders 44 are fixedly connected through springs; on one side of the outer walls of the pair of sliders 44, they are respectively slidably connected to one side of the outer walls of the pair of vertical plates 42; dampers are arranged at the connection parts of the pair of springs and the adjusting blocks 43; at one end of the outer walls of the pair of sliders 44, auxiliary rollers 45 are respectively rotatably connected, and the pair of auxiliary rollers 45 respectively match with the pair of conveying rollers 30. When the conveying rollers 30 convey the material, the sliders 44 and the auxiliary rollers 45 move downward by the elastic force of the springs, so that the auxiliary rollers 45 cooperate with the conveying rollers 30 to squeeze the material. When the conveying rollers 30 convey the material, since the material is squeezed by the auxiliary rollers 45 and the conveying rollers 30, the friction force of the rotation of the conveying rollers 30 on the material increases, so that the conveying rollers 30 can convey the material better, thus avoiding idling, and the auxiliary rollers 45 are driven to rotate passively by the friction force of the material for auxiliary conveying, making the conveying effect of the material better.

[0036] One side of the outer wall of the adjusting block 43 is slidably connected to one side of the outer wall of the vertical plate 42; one side of the outer wall of the vertical plate 42 is threadedly connected with a first threaded rod 46 through a first square block; the bottom end of the outer wall of the first threaded rod 46 is rotatably connected to the top end of the outer wall of the adjusting block 43. By rotating the first threaded rod 46, since the first threaded rod 46 is threadedly connected with the first square block, the rotation of the first threaded rod 46 drives the first threaded rod 46 to move up and down, and the up and down movement of the first threaded rod 46 drives the adjusting block 43 to move up and down, so that the adjusting block 43 drives the spring, the slider 44 and the auxiliary roller 45 to move up and down, enabling the device to adjust the strength of the spring according to the situation of the material, so that the auxiliary roller 45 can better cooperate with the conveying roller 30 to convey the material, thus avoiding the problem that the clamping force between the conveying roller 30 and the auxiliary roller 45 is too large or too small, enabling the device to adapt to the change of the fabric thickness, avoiding excessive local pressure, and making the accuracy of the material after cutting treatment better.

[0037] The bottom end of the outer wall of the guiding rod 54 is fixedly connected to the top end of the outer wall of the first connecting shell 55, and the top end of the outer wall of the guiding rod 54 penetrates through the reciprocating plate 53; the guiding rod 54 is slidably connected with the reciprocating plate 53; the bottom end of the outer wall of the first connecting shell 55 is rotatably connected with a sixth threaded rod 57, and the top end of the outer wall of the sixth threaded rod 57 penetrates through the reciprocating plate 53; the sixth threaded rod 57 is threadedly connected with the reciprocating plate 53. By rotating the sixth threaded rod 57, since the sixth threaded rod 57 is threadedly connected with the reciprocating plate 53, the rotation of the sixth threaded rod 57 drives the sixth threaded rod 57 to move up and down, thereby driving the first connecting shell 55 and the first flattening roller 56 to move up and down, so that the device can adjust the position of the first flattening roller 56 according to the situation of the material, making the first flattening roller 56 better fit the material for operation.

[0038] A pair of annular limiting blocks 47 are arranged on the outer side wall of the auxiliary roller 45, and the annular limiting blocks 47 are arc-shaped; the annular limiting blocks 47 are matched with the conveying roller 30; one side of the outer wall of the slider 44 is rotatably connected with a double threaded rod 48, and one end of the outer wall of the double threaded rod 48 penetrates through a pair of annular limiting blocks 47; the double threaded rod 48 is threadedly connected with a pair of annular limiting blocks 47; the inner side wall of the annular limiting blocks 47 is mutually attached to the outer side wall of the auxiliary roller 45. By rotating the double threaded rod 48, since the double threaded rod 48 is threadedly connected with a pair of annular limiting blocks 47, the rotation of the double threaded rod 48 drives a pair of annular limiting blocks 47 to move towards the center or both sides simultaneously, enabling the device to adjust the position of the annular limiting blocks 47 according to the situation of the material, making a pair of annular limiting blocks 47 located on both sides of the material being conveyed to limit the material, so that the material is not easily displaced during conveying, thereby further improving the effect and accuracy of the material during cutting.

[0039] Embodiment 2:

[0040] Please refer to Figure 1 and Figure 8 - Figure 9As shown in the figure, a reciprocating rod eight 58 is rotatably connected to one side of the outer wall of the reciprocating plate 53; a telescopic housing 59 is arranged on the outer side wall of the reciprocating rod eight 58; a connecting housing two 60 is fixedly connected to the bottom end of the outer wall of the telescopic housing 59; a flattening roller two 61 is arranged on the inner side wall of the connecting housing two 60; a telescopic rod 62 is fixedly connected to one side of the outer wall of the connecting housing one 55, and one end of the outer wall of the telescopic rod 62 is fixedly connected to the outer side wall of the connecting housing two 60; a gear ten 63 is fixedly connected to the outer side wall of the reciprocating rod eight 58; a rack ten 64 is fixedly connected to one side of the outer wall of the auxiliary plate 49 through a connecting block eight, and the gear ten 63 and the rack ten 64 are meshed with each other. When the reciprocating plate 53 reciprocates, the reciprocating plate 53 drives the reciprocating rod eight 58 and the gear ten 63 to reciprocate. Because the gear ten 63 and the rack ten 64 are meshed with each other and the rack ten 64 is in a fixed state, when the gear ten 63 moves, it rotates through the rack ten 64, thereby driving the reciprocating rod eight 58 to rotate. The rotation of the reciprocating rod eight 58 drives the telescopic housing 59 to reciprocate, thereby driving the connecting housing two 60 and the flattening roller two 61 to reciprocate, so that the flattening roller two 61 performs secondary flattening on the material. And because the moving directions of the flattening roller two 61 and the flattening roller one 56 are different, the flattening effect of the device on the material is better. And when the height of the flattening roller one 56 is adjusted, the telescopic rod 62 drives the connecting housing two 60 and the flattening roller two 61 to move up and down for adjustment. At this time, the telescopic housing 59 expands and contracts to ensure that the flattening roller two 61 can move up and down, so that the flattening roller one 56 and the flattening roller two 61 are always at the same height. When the flattening roller two 61 reciprocates, the telescopic rod 62 expands and contracts to ensure that the flattening roller two 61 can reciprocate.

[0041] When the present invention is in use, the motor 16 drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the rotating rod one 24 to rotate through the sprocket one 28 and the chain one 29. The rotating rod one 24 drives the gear disc 25 to rotate. When the gear groove one 26 on the gear disc 25 is about to encounter the semi-gear nine 22, the hinged reset plate one 27 will contact the reset rod one 23. At this time, the reset plate one 27 changes its angle and gives a squeezing force to the reset rod one 23. The reset rod one 23 transmits the force to the semi-gear nine 22. When the semi-gear nine 22 encounters the gear groove one 26, under the action of the force, the teeth of the semi-gear nine 22 will be stuck into the gear groove one 26. At this time, the rotation of the gear disc 25 drives the semi-gear nine 22 to rotate. When the semi-gear nine 22 rotates most of a circle, the two outer teeth of the semi-gear nine 22 will abut against the plane of the gear disc 25. At this time, when the gear disc 25 rotates, the semi-gear nine 22 is stuck in position and will not rotate until it encounters the gear groove one 26 before it will rotate, so that the semi-gear rotates most of a circle and then stops and is blocked at the same time. The rotation of the semi-gear nine 22 drives the rotating rod 20 to rotate. The rotating rod 20 drives the gear three 21 to rotate. The gear three 21 drives the gear two 19 to rotate. The gear two 19 drives the reciprocating rod one 7 to rotate. Because the radius of the gear three 21 is larger than the radius of the gear two 19, the gear three 21 rotates most of a circle, while the gear two 19 and the reciprocating rod one 7 rotate several circles.

[0042] When the reciprocating rod 7 rotates, the rotation of the reciprocating rod 7 drives the slide plate 5 to reciprocate up and down, causing the slide plate 5 to drive the upper knife body 3 to reciprocate. When the upper knife body 3 reciprocates, the upper knife body 3 drives the first rack 10 to move up and down through the first connecting block. Since both the second rack 14 and the first rack 10 are meshed with the first gear 11, the movement of the first rack 10 drives the first gear 11 to rotate. The rotation of the first gear 11 drives the second rack 14 to move up and down, and the up and down movement direction is opposite to that of the first rack 10. When the upper knife body 3 descends, the lower knife body 13 ascends. At this time, the upper knife body 3 cuts the material above the material, and the lower knife body 13 cuts the material below the material through the third through groove 15 and the cutting groove 8, making the cutting of the material more convenient. Moreover, because the upper and lower blades share the cutting force, the force on a single blade is reduced, the wear is reduced, and the cutting process is smoother. This not only prolongs the service life of the blades, but also reduces the cutting error caused by blade jamming, making the precision of the upper knife body 3 cooperating with the lower knife body 13 to cut synchronously from the top and bottom of the fabric higher, and the upper knife body 3 cooperating with the lower knife body 13 to cut into the fabric synchronously from the top and bottom, and ensuring that the upper and lower blades are completely coincident through the precision alignment system. The fabric is clamped during the cutting process, with uniform force, effectively suppressing the lateral displacement and local stretching, and significantly improving the flatness of the cutting edge.

[0043] The rotating shaft 18 is driven to rotate by the motor 16, causing the rotating shaft 18 to drive the disc 38 to rotate. The disc 38 drives the semi-gear eight 36 to rotate through the third gear slot 39. The semi-gear eight 36 drives the third rotating rod 32 to rotate. The third rotating rod 32 drives the fourth rotating rod 33 to rotate through the second sprocket 34 and the second chain 35, thereby driving a pair of conveying rollers 30 to rotate. The rotation of the pair of conveying rollers 30 drives the material to be conveyed to the upper tool body 3 and the lower tool body 13 for cutting. When the disc 38 drives the semi-gear eight 36 to rotate, the third reset plate 41 will first encounter the third reset rod 37 and apply pressure to the third reset rod 37. The third reset rod 37 transmits the pressure to the semi-gear eight 36. When the semi-gear eight 36 encounters the third gear slot 39, the teeth of the semi-gear eight 36 are engaged in the third gear slot 39, causing the disc 38 to drive the semi-gear eight 36 to rotate. When the semi-gear eight 36 rotates to a place without teeth, another third reset plate 41 will contact the third reset rod 37 again, causing the semi-gear eight 36 to rotate until the semi-gear eight 36 rotates to a position where the disc 38 has no third gear slot 39. At this time, the two outer teeth of the semi-gear eight 36 are stuck by the outer wall of the disc 38 and cannot rotate until it encounters the third gear slot 39 again. This enables the double-knife cutting mechanism, the driving mechanism, and the material conveying mechanism to cooperate with each other. The motor 16 drives the rotating shaft 18 to rotate continuously, causing the semi-gear eight 36 to rotate several times to convey the material, and then the semi-gear eight 36 stops to stop the material conveying. At this time, the gear disc 25 drives the semi-gear nine 22 to rotate, causing the upper tool body 3 and the lower tool body 13 to perform cutting. After the cutting is completed, the semi-gear nine 22 stops, and the semi-gear eight 36 continues to rotate, thus repeating the cycle. The material is conveyed to a certain length and then stops. Then the upper tool body 3 and the lower tool body 13 perform cutting. Then the material continues to be conveyed. When the material is being cut, the material does not move, so that when the material is being cut, the accuracy is higher, and only a single motor 16 is required to complete the conveying and cutting of complex materials, making the device more flexible and convenient, reducing the use of power sources, and lowering energy consumption and costs.

[0044] When the conveying rollers 30 convey the material, the slider 44 and the auxiliary roller 45 are moved downward by the elastic force of the spring, so that the auxiliary roller 45 cooperates with the conveying rollers 30 to squeeze the material. When the conveying rollers 30 convey the material, since the material is squeezed by the auxiliary roller 45 and the conveying rollers 30, the friction force of the rotation of the conveying rollers 30 on the material increases, enabling the conveying rollers 30 to convey the material better, thereby avoiding idling. Moreover, the auxiliary roller 45 rotates passively through the friction force of the material to assist in conveying, making the conveying effect of the material better.

[0045] When the rotating shaft 18 rotates, the rotation of the rotating shaft 18 drives the reciprocating rod five 50 to rotate through a pair of gears seven 51. The rotation of the reciprocating rod five 50 drives the reciprocating plate 53 to reciprocate. Since the reciprocating plate 53 is limited by the limiting plate 52, the reciprocating plate 53 can only reciprocate and cannot rotate. The reciprocating motion of the reciprocating plate 53 drives the smoothing roller one 56 to move through the guiding rod 54 and the connecting shell one 55. When the material is conveyed and cut, the movement of the smoothing roller one 56 can smooth the wrinkles or unevenness on the material, so that the material can be cut more accurately and errors are not likely to occur.

[0046] By rotating the threaded rod six 57, since the threaded rod six 57 is threadedly connected to the reciprocating plate 53, the rotation of the threaded rod six 57 drives the threaded rod six 57 to move up and down, thereby driving the connecting shell one 55 and the smoothing roller one 56 to move up and down. Thus, the device can adjust the position of the smoothing roller one 56 according to the condition of the material, so that the smoothing roller one 56 can better fit the material for operation.

[0047] When the reciprocating plate 53 reciprocates, the reciprocating plate 53 drives the reciprocating rod eight 58 and the gear ten 63 to reciprocate. Since the gear ten 63 meshes with the rack ten 64 and the rack ten 64 is in a fixed state, when the gear ten 63 moves, it rotates through the rack ten 64, thereby driving the reciprocating rod eight 58 to rotate. The rotation of the reciprocating rod eight 58 drives the telescopic housing 59 to reciprocate, thereby driving the connecting shell two 60 and the smoothing roller two 61 to reciprocate, so that the smoothing roller two 61 performs secondary smoothing on the material. And because the moving directions of the smoothing roller two 61 and the smoothing roller one 56 are different, the smoothing effect of the device on the material is better. And when the height of the smoothing roller one 56 is adjusted, the telescopic rod 62 drives the connecting shell two 60 and the smoothing roller two 61 to move up and down for adjustment. At this time, the telescopic housing 59 expands and contracts to ensure that the smoothing roller two 61 can move up and down, so that the smoothing roller one 56 and the smoothing roller two 61 are always at the same height. When the smoothing roller two 61 reciprocates, the telescopic rod 62 expands and contracts to ensure that the smoothing roller two 61 can reciprocate.

[0048] By rotating the threaded rod one 46, since the threaded rod one 46 is threadedly connected to the square block one, the rotation of the threaded rod one 46 drives the threaded rod one 46 to move up and down. The up and down movement of the threaded rod one 46 drives the adjusting block 43 up and down, so that the adjusting block 43 drives the spring, the slider 44 and the auxiliary roller 45 to move up and down. The device can adjust the strength of the spring according to the condition of the material, so that the auxiliary roller 45 can better cooperate with the conveying roller 30 to convey the material, thereby avoiding the problem that the clamping force between the conveying roller 30 and the auxiliary roller 45 is too large or too small, enabling the device to adapt to the change of the fabric thickness, avoiding excessive local pressure, and making the accuracy of the material after cutting and processing better.

[0049] By rotating the double-threaded rod 48, since the double-threaded rod 48 is threadedly connected to a pair of annular limit blocks 47, the rotation of the double-threaded rod 48 drives the pair of annular limit blocks 47 to move towards the center or to both sides simultaneously, enabling the device to adjust the positions of the annular limit blocks 47 according to the situation of the material, so that the pair of annular limit blocks 47 are located on both sides of the material being conveyed to limit the material, making it difficult for the material to shift during conveyance, thereby further improving the effect and accuracy during the cutting of the material.
