Description

Technical Field

[0001] The invention relates to the technical field of protective fabric processing, and in particular to a cutting device for producing high-performance protective fabric. Background Art

[0002] High-performance protective fabrics are a type of fabric with special properties and functions, specially designed to provide effective protection for the human body in various dangerous and extreme environments. In terms of performance, high-performance protective fabrics have excellent flame retardant properties, can quickly carbonize to form a heat insulation layer when exposed to fire, prevent the spread of flames, and protect the human body from burns. They have good anti-static properties and can effectively prevent static electricity accumulation and discharge, avoiding fires or explosions in flammable and explosive environments. Before high-performance protective fabrics are made into products, the entire piece of protective fabric needs to be cut into fabrics of the required size, so the protective fabrics need to be cut by cutting equipment;

[0003] However, when the cutting equipment in the prior art cuts the fabric, due to the continuous friction and collision between the cutting blade and the protective fabric, the microstructure of the surface of the cutting blade is gradually worn, the sharpness of the cutting blade is reduced, the cutting edge becomes round and blunt, and the cutting force is reduced. The protective fabric needs to be cut multiple times to cut the protective fabric, which makes it impossible to cut the protective fabric in one time and the fabric cannot be cut smoothly. When the cutting blade cuts the fabric at high speed, each cut will have a certain impact on the blade. As the number of cuts increases, this repeated impact will cause the micro cracks of the cutting blade to expand and the material fatigue, thereby reducing the strength and sharpness of the blade, resulting in reduced cutting efficiency of the protective fabric. At the same time, when the protective fabric is cut multiple times, the cut of the protective fabric will be uneven, and multiple cutting of the protective fabric will reduce the quality of the protective fabric cutting.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When the fixed plate is pushed and the whole plate is moved downward by the telescopic shaft of the hydraulic rod, the stable plate is first in contact with the fabric by compressing the spring in the maximum tension state. During the continuous downward push, the stable plate makes the moving rod on the upper surface of the stable plate slide upward after being blocked. When the stable plate slides downward, the length and inclination angle of the moving connecting rod can push the connected movable plate and movable sleeve to slide. The sliding of the movable sleeve can slide the movable plate and the grinding sleeve horizontally to one side. The grinding groove block can make the cutting blade sharper, so that the edge of the cut fabric can be neat and smooth, and the size error can be controlled within a very small range, which improves the consistency and quality stability of the product.

[0020] When the grinding sleeve and the grinding groove block slide horizontally, the thrust of the spring of compression spring 3 can make the cleaning roller tightly fit against the two sides of the cutting blade. The cleaning roller moves on both sides of the cutting blade to remove the fine debris rubbed by the two sides of the cutting blade and the silk thread adhered when cutting the fabric, so that the cutting blade always maintains the best cutting state, ensuring that the cutting blade always maintains good sharpness and cutting performance during the cutting process, thereby improving the cutting quality and efficiency;

[0021] The rubbing of the cutting blade on both sides during fabric fixing and fabric separation can ensure that the rubbing of the cutting blade on both sides is carried out without stopping the machine, and the rubbing of the cutting blade on both sides during fabric cutting can be effectively improved on this basis, and the rubbing of the cutting blade on both sides during fabric cutting does not need to be disassembled and rubbed, and the rubbing of the cutting blade can be completed during fabric cutting, thereby increasing the sharpness of the cutting blade, and the protection effect of the cutting blade can be improved by resetting the rubbing sleeve when the fabric is not cut.

[0022] Wherein: since the cutting blade edge is in the V-shaped groove on the surface of the grinding groove block, and both sides of the cutting blade edge are in contact with the inner wall of the V-shaped groove of the grinding groove block, when the grinding groove block slides synchronously with the grinding sleeve horizontally, the two sides of the cutting blade edge can be rubbed by the friction effect of the grinding groove block, and the grinding sleeve and the grinding groove block rub the two sides of the cutting blade edge in a reciprocating cycle to improve the sharpness of the cutting blade edge, so that the fabric can be cut more easily, thereby improving the efficiency of fabric cutting;

[0023] Wherein: the grinding sleeve and the grinding groove block can be horizontally slid and reset again by the rebound force of the second compression spring, and the grinding sleeve and the grinding groove block rub the two sides of the cutting blade edge in a reciprocating cycle to make the surfaces of the two sides of the cutting blade edge smoother and flatter, thereby improving the sharpness of the cutting blade edge;

[0024] Among them: since the compression spring three is in the maximum tension state, the two cleaning rollers can contact each other, and when the cleaning roller follows the grinding sleeve to slide horizontally and synchronously, the cleaning roller will move and contact the two sides of the cutting blade. Through the cyclic movement of the cleaning roller on both sides of the cutting blade, external factors can be effectively prevented from interfering with the normal contact and cutting between the cutting blade and the fabric, ensuring that the cutting blade always maintains good sharpness and cutting performance during the cutting process, thereby improving the cutting quality and efficiency.

[0025] 2. The extension and retraction of the telescopic shaft of the hydraulic rod can realize the cutting blade to contact with the fabric for cutting and the cutting blade to reset its position. When the adjusting gear is moved to mesh with the moving rack through the telescopic shaft of the micro-electric gas rod, the moving rack follows the extension plate and the fixed plate to slide up synchronously through the connection of the extension plate and the limit sliding sleeve, and the upward sliding of the moving rack can make the meshing adjusting gear rotate. Therefore, the belt transmission makes the rotating rod, the conveying roller and the transmission belt rotate with the rotating shaft. Since the fabric is placed on the upper surface of the transmission belt, the cutting can be realized under the transmission of the transmission belt. The cutting blade and the stabilizing platen are separated from the cut fabrics and reset to ensure continuous feeding of new fabrics. Since the feeding action is started when the cutting blades slide upward, the two realize precise action synchronization, so that the fabrics can be accurately transported to the cutting position, avoiding cutting errors and waste caused by inaccurate feeding. At the same time, this mechanical transmission method has high stability and reliability, can work stably for a long time, reduces production interruptions and quality problems caused by equipment failures or human errors, and ensures the stability of the production process and the consistency of product quality.

[0026] Compared with the prior art of direct feeding with a conveyor belt, there is no direct correlation and coordination between the rotation of the conveyor belt and the movement of the cutting blade. The conveyor belt usually runs continuously to feed the material at a preset speed and time. The timing and position of feeding are relatively fixed and rough, and it is difficult to make precise adjustments and coordination according to the real-time movement of the cutting blade. This can easily lead to the position of the fabric on the conveyor belt and the position of the cutting blade being inaccurate, thereby affecting the cutting accuracy and quality, and easily causing problems such as cutting deviation and fabric waste.

[0027] When the fixed plate slides upward through the contraction of the hydraulic rod, the position of the movable rack can be limited by the limit rod and the limit sleeve, so that the movable rack can always maintain the vertical sliding effect at the same position, and the separation and meshing effect can be achieved between the adjusting gear and the movable rack;

[0028] Among them: the telescopic shaft of the micro electric gas rod is telescopic and extended, which can enable the adjustment gear and the moving rack to be separated and engaged. At the same time, the blocking force generated by the cross shape of the limiting groove and the limiting convex strip makes the rotating shaft and the adjusting gear rotate when sliding on the moving rack, thereby achieving the effect of timed feeding of the fabric on the transmission belt.

[0029] 3. When the fixed plate and the cutting blade are pushed down by the telescopic shaft of the hydraulic rod, the flattening roller and the connecting plate at the bottom of the stable platen first contact with the fabric, which can effectively prevent the position deviation and dislocation of the fabric on the transmission belt and improve the accuracy of the fabric position. When the flattening roller contacts the fabric, the hydraulic rod continues to push the fixed plate and the cutting blade down. At this time, the stable platen and the moving rod will slide inside the fixed plate under the resistance of the fabric, so that the compression spring 1 is compressed. The compression of the compression spring 1 can reset the stable platen and the grinding sleeve when the stable platen is separated from the fabric. After the flattening roller and the connecting plate contact the fabric, Hot air can be blown into the stabilizing platen by heating the electric heating wire and starting the fan, and the heat of the stabilizing platen can be transferred to the connecting platen through the connecting pipe, so that the heat can be shared between the stabilizing platen and the connecting platen, which can reduce the effect of thermal cost. The heat is blown to the surface of the fabric through the air outlet, and when the fabric is subjected to heat, the fabric undergoes a certain degree of heat setting during the cutting process. The fabric after heat setting can maintain the shape and size after cutting, reducing the deformation and size change caused by the elastic recovery and stress relaxation of the fabric, which is conducive to improving the matching and assembly accuracy of the cut fabric with other components;

[0030] Wherein: two connecting pressing plates are arranged at the front and rear ends of the cutting blade. When the cutting blade moves and cuts, the two connecting pressing plates move at the position of the fabric cutting line, so as to smooth the fabric before cutting and prevent wrinkles. The fabric after cutting is prevented from warping at the cutting edge by the hot air from the connecting pressing plates.

[0031] Among them: four flattening rollers are used to stably resist four positions of the fabric respectively, so as to prevent the fabric from shrinking at the cutting position when the fabric is cut, thereby reducing the deformation of the fabric during the cutting process;

[0032] Wherein: when the compression spring is in the maximum tension state, the stabilizing plate and the connecting plate are firstly close to the fabric, and under the resistance of the elastic force of the compression spring, the flattening roller at the bottom of the stabilizing plate and the connecting plate are firstly in resistance with the fabric, which can effectively prevent the fabric position on the transmission belt from being offset or misaligned.

DETAILED DESCRIPTION

[0043] 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.

[0044] See also Figures 1 to 8 As shown, the present invention provides an embodiment: a cutting device for producing high-performance protective fabrics, comprising a base 1, a conveying roller 2, the conveying roller 2 is symmetrically rotatably connected inside the base 1, a conveying belt 3 is connected between the two conveying rollers 2, a support plate 4 is fixedly connected to the outside of the base 1, and a sliding mechanism is arranged inside the support plate 4, and further comprising:

[0045] The flattening and stabilizing component 7 is used to stabilize and smooth the fabric before and during cutting, thereby improving the smoothness of the fabric cutting;

[0046] A grinding and cleaning component 8 is used to perform cyclic grinding on the blade edge and simultaneously process the residual debris or threads on the surface of the blade;

[0047] The circulating feeding component 9 is used for circulating the fabric to improve the overall feeding efficiency;

[0048] The support plate 4 is internally slidably connected with a hydraulic rod 5, the bottom end of the telescopic shaft of the hydraulic rod 5 is fixedly connected with a fixed plate 6, the lower surface of the fixed plate 6 is fixedly connected with a micro electric pneumatic rod 10, and the bottom end of the telescopic shaft of the micro electric pneumatic rod 10 is fixedly connected with a cutting blade 11.

[0049] The flattening stabilizing assembly 7 includes four moving rods 701 symmetrically slidably connected inside the fixed plate 6, and a stabilizing pressure plate 702 is symmetrically arranged at the bottom of the fixed plate 6. The bottom ends of the four moving rods 701 are respectively fixedly connected to the stabilizing pressure plates 702, and the tops of the moving rods 701 are fixedly connected to connecting pressure plates 703. The outer wall of the moving rod 701 is sleeved with a compression spring 705, and the two ends of the compression spring 705 are respectively fixedly connected to the fixed plate 6 and the stabilizing pressure plate 702, and the side where the two stabilizing pressure plates 702 are close to each other is fixedly connected to the connecting pressure plate 703. The stabilizing pressure plate 702 and the connecting pressure plate 7 03 are provided with heating grooves 706 inside, connecting plates 703 and stabilizing plates 702 are fixedly connected with connecting pipes 707, the fixing plates 6 are symmetrically fixedly connected with fixing cylinders 708 inside, the fixing cylinders 708 are respectively fixedly connected with fans 709 and electric heating wires 710 inside, the fixing cylinders 708 and the stabilizing plates 702 are fixedly connected with connecting hoses 711 on the sides close to each other, the stabilizing plates 702 and the connecting plates 703 are provided with air outlet holes 712 arranged in a linear array at the bottom, and the stabilizing plates 702 are symmetrically rotatably connected with four flattening rollers 713 at the bottom;

[0050] Specifically, when the four flattening rollers 713 in the flattening and stabilizing assembly 7 and the bottom of the two connecting pressure plates 703 come into contact with the fabric, the flattening rollers 713 and the connecting pressure plates 703 can first perform a preliminary position stabilization on the position of the fabric placed on the upper surface of the transmission belt 3, and the heat in the stabilizing pressure plate 702 and the connecting pressure plate 703 is blown onto the surface of the fabric through the air outlet 712. After the fabric is heated, the movement of the fiber molecular segments therein intensifies, and the cohesive force of the material decreases, causing the fabric to soften as a whole. This softening makes the fabric easier to be cut by the cutting blade 11 during the cutting process, reduces the resistance encountered by the cutting blade 11 during the cutting process, thereby making the cutting smoother and improving the cutting efficiency. Since the two connecting pressure plates 703 are arranged at the front and rear ends of the cutting blade 11, during the movement and cutting process of the cutting blade 11, the two connecting pressure plates 703 move to the position of the fabric cutting line, which can smoothen the fabric before cutting and prevent wrinkles.

[0051] The grinding and cleaning component 8 includes a fixed groove 801 symmetrically opened inside the fixed plate 6, the inside of the fixed groove 801 is fixedly connected to a fixed rod 802, the outer wall of the fixed rod 802 is slidably connected to a movable sleeve 803, the outer wall of the movable sleeve 803 is fixedly connected to a movable plate 804, the outer wall of the movable sleeve 803 is sleeved with a compression spring 806, the two ends of the compression spring 806 are respectively fixedly connected to the movable plate 804 and the fixed groove 801, the side close to the stabilizing plate 702 and the movable plate 804 is rotatably connected to a movable connecting rod 805, and the movable sleeve The ends of 803 away from the movable plate 804 are fixedly connected to the movable plate 807, the ends of the movable sleeves 803 away from the movable plate 804 are all penetrated inside the fixed plate 6, the bottom of the cutting blade 11 is slidably connected to the grinding sleeve 808, the ends of the movable plate 807 away from the movable sleeve 803 are fixedly connected to the grinding sleeve 808, the grinding sleeve 808 has a sliding groove inside, the inner wall of the sliding groove is fixedly connected to a grinding groove block 809, the upper surface of the grinding groove block 809 has a V-shaped groove, and the bottom of the cutting blade 11 slides in the V-shaped groove of the grinding groove block 809;

[0052] The grinding and cleaning component 8 also includes four mounting grooves 810 symmetrically arranged inside the grinding sleeve 808, and movable rods 811 are slidably connected inside the mounting grooves 810, and the ends of the movable rods 811 close to the cutting blade 11 are fixedly connected to the fixing frame 813, and the inner side of the fixing frame 813 is rotatably connected to the cleaning roller 814, and the ends of the movable rods 811 away from the fixing frame 813 are fixedly connected to the baffle plate 2 812, and the outer walls of the movable rods 811 are fixedly connected to the baffle plate 3 815, and the outer walls of the movable rods 811 are sleeved with compression springs 3 816, and the two ends of the compression springs 3 816 are fixedly connected to the baffle plate 3 815 and the mounting grooves 810, respectively, and four hidden grooves 817 are symmetrically arranged inside the grinding sleeve 808, and the fixing frame 813 and the cleaning roller 814 slide inside the hidden grooves 817, and the baffle plate 3 815 and the compression spring 3 816 are both located inside the mounting grooves 810;

[0053] Specifically, the movable connecting rod 805 in the grinding and cleaning component 8 rotates during the sliding of the fixed plate 6, so that the movable connecting rod 805 pushes the movable plate 804, the movable sleeve 803, the movable plate 807, the grinding sleeve 808 and the grinding groove block 809 to slide horizontally. Since the bottom of the blade of the cutting blade 11 fits with the V-shaped groove on the surface of the grinding groove block 809, friction is generated between the two sides of the blade of the cutting blade 11 during the horizontal horizontal sliding of the grinding groove block 809, and the friction force makes the two sides of the blade of the cutting blade 11 smoother, thereby improving the sharpness of the blade of the cutting blade 11. The sharp cutting blade 11 can cut the fabric cleanly, so that the cutting edge is neat and smooth, without burrs or drawing, and the fiber structure of the fabric will not be excessively damaged due to cutting, thereby maintaining the original physical properties and protective functions of the fabric.

[0054] The circulating feeding assembly 9 includes an extension plate 901 fixedly connected to the outside of the fixed plate 6, a limiting rod 910 fixedly connected inside the support plate 4, a limiting sleeve 911 slidably connected to the outer wall of the limiting rod 910, an end of the limiting sleeve 911 away from the limiting rod 910 is slidably connected to the outer wall of the extension plate 901, a movable rack 902 is fixedly connected to the bottom of the limiting sleeve 911, an end of the extension plate 901 away from the fixed plate 6 passes through the inside of the support plate 4, a rotating rod 903 is fixedly connected to the inside of the conveying roller 2, and a rotating shaft 904 is rotatably connected to the inside of the base 1 and the support plate 4, and the two rotating rods 903 and the rotating shaft 904 are connected. The inner wall of the support plate 4 is fixedly connected with a micro electric gas rod 905, and the telescopic shaft of the micro electric gas rod 905 is fixedly connected with a connecting plate 906.

A limiting convex strip 909 is fixedly connected to the outer wall of the rotating shaft 904. The limiting convex strip 909 is slidably connected to the inside of the limiting groove 908, and the adjusting gear 907 is meshed with the movable rack 902;

[0055] Specifically, when the micro-electric gas rod 905 in the circulating feeding component 9 pushes the adjusting gear 907 to engage with the moving rack 902, the hydraulic rod 5 drives the fixed plate 6 and the cutting blade 11 to slide up, so that the sliding of the moving rack 902 drives the adjusting gear 907 engaged therewith to rotate, and the rotation of the adjusting gear 907 drives the rotating shaft 904, the rotating rod 903, the conveying roller 2 and the transmission belt 3 to transmit, so that the cloth on the surface of the transmission belt 3 can be moved to a fixed position, and the fabric can be accurately fed during the sliding of the fixed plate 6. Since the feeding action is triggered at a specific moment when the cutting blade 11 slides up, precise action synchronization is achieved between the two. This synchronous control can ensure that the timing and position of each feeding are very accurate, so that the fabric can be accurately transported to the cutting position, avoiding cutting errors and waste caused by inaccurate feeding.

[0059] Reference Figure 4 , Figure 6 and Figure 7 As shown, the height of the cleaning roller 814 is between 1.5 and 2 times the height of the cutting blade 11, and the center of the cutting blade 11 and the center of the grinding sleeve 808 are on the same vertical line;

[0060] In combination with the above preferred embodiments, the working principle of the present invention is as follows:

[0061] In the initial state, the telescopic shaft of the hydraulic rod 5 is in a retracted state, the moving rod 701 is in an uncompressed state, the fan 709 and the electric heating wire 710 are both in a closed state, the compression spring 2 806 is in an uncompressed state, the telescopic shaft of the micro electric pneumatic rod 2 10 is in a retracted state, the cutting blade 11 is in the middle position between the two sets of cleaning rollers 814, the grinding sleeve 808 and the cutting blade 11 are in an unseparated state, the compression spring 3 816 is in an uncompressed state, the telescopic shaft of the micro electric pneumatic rod 1 905 is in a retracted state, and the adjusting gear 907 and the moving rack 902 are in a separated state.

[0062] When working:

[0063] The fabric is moved to the position below the cutting blade 11 by the transmission action of the transmission belt 3. The staff electrically controls the telescopic shaft of the hydraulic rod 5 through the controller to extend and push the fixed plate 6 connected thereto to slide down. The sliding of the fixed plate 6 drives the micro-electric gas rod 10 and the cutting blade 11 to slide down synchronously. When the bottoms of the four flattening rollers 713 and the two connecting pressure plates 703 are in conflict with the fabric, the flattening rollers 713 and the connecting pressure plates 703 can first perform a preliminary position stabilization on the position of the fabric placed on the upper surface of the transmission belt 3. The controller electrically controls the fan 709 to start generating wind, and the electric heating wire 710 starts heating, and the heated wind enters the stabilizing plate 702 through the connecting hose 711, and the heat in the stabilizing plate 702 enters the connecting plate 703 through the connecting pipe 707, and the heat in the stabilizing plate 702 and the connecting plate 703 is blown onto the surface of the fabric through the air outlet 712. After the fabric is heated, the movement of the fiber molecular segments therein intensifies, and the cohesive force of the material decreases, causing the fabric to soften as a whole. This softening The fabric is made easier to be cut by the cutting blade 11 during the cutting process, and the resistance of the cutting blade 11 during the cutting process is reduced, so that the cutting becomes smoother and the cutting efficiency is improved. Since the fabric softened by heat is easier to deform and flow, under the action of the cutting blade 11, the fabric can better fit the shape and movement trajectory of the cutting blade 11, reducing the cutting deviation caused by the rigid resistance of the fabric, thereby improving the cutting accuracy and dimensional stability. In addition, since the two connecting pressing plates 703 are arranged at the front and rear ends of the cutting blade 11, during the movement and cutting process of the cutting blade 11, the two connecting pressing plates 703 move at the position of the fabric cutting line, which can smooth the fabric before cutting and prevent wrinkles. The fabric after cutting is prevented from warping the cutting edge of the fabric under the action of the hot air of the connecting pressing plates 703. In addition, the four flattening rollers 713 respectively resist the four positions of the fabric stably, which can prevent the fabric at the cutting position from shrinking when the fabric is cut, thereby reducing the deformation of the fabric during the cutting process.

[0064] When the bottoms of the four flattening rollers 713 and the two connecting pressure plates 703 come into contact with the fabric, the telescopic shaft of the hydraulic rod 5 continues to extend to push the fixed plate 6 down. As a result, the flattening rollers 713, the connecting pressure plates 703 and the stabilizing pressure plate 702 are blocked by the fabric and the transmission belt 3, so that the moving rod 701 and the baffle plate 704 above the stabilizing pressure plate 702 slide up. At this time, under the blockage of the fabric and the transmission belt 3, the flattening rollers 713, the connecting pressure plates 703 and the stabilizing pressure plate 702 are in a stationary state, and the fixed plate 6 continues to approach the stabilizing pressure plate 702 under the extension of the hydraulic rod 5. Therefore, when the distance between the fixed plate 6 and the stabilizing pressure plate 702 is reduced, the length and angle of the moving connecting rod 805 are used to tilt the fixed plate 6. Under the action of , one end of the two moving links 805 rotates, and under the action of the length of the moving link 805, the moving link 805 at one end connected to the movable plate 804 moves in the fixed groove 801, and the sliding of the movable plate 804 drives the movable sleeve 803 fixedly connected thereto to slide on the surface of the fixed rod 802, and the movement of the movable sleeve 803 drives the moving plate 807 fixedly connected thereto to slide horizontally and laterally synchronously, and at this time the compression spring 806 is in a compressed state, and when the moving plate 807 slides horizontally and laterally, it drives the grinding sleeve 808 fixedly connected thereto to slide horizontally and laterally, and slides the grinding sleeve 808 to a position away from the cutting blade 11, and due to the V-shaped groove on the surface of the grinding groove block 809 and the bottom of the blade of the cutting blade 11 When the grinding sleeve 808 slides horizontally, it drives the grinding groove block 809 fixedly connected thereto to slide horizontally synchronously. When the grinding groove block 809 slides horizontally, friction is generated with both sides of the blade of the cutting blade 11. The friction makes both sides of the blade of the cutting blade 11 smoother, thereby improving the sharpness of the blade of the cutting blade 11. When the telescopic shaft of the hydraulic rod 5 drives the fixed plate 6, the micro-electric gas rod 10 and the cutting blade 11 to slide upward, the movable sleeve 803, the movable plate 804 and the stabilizing pressure plate 702 are pushed to reset their positions by the compression rebound force of the two compression springs 2 806 and the multiple compression springs 1 705 themselves, so that the reset of the movable sleeve 803 drives the movable plate 807, the grinding sleeve 808 and the grinding groove block. 809 is synchronously reset, so that the grinding groove block 809 is reset to wrap the cutting blade 11, and when the grinding groove block 809 is reset, the grinding groove block 809 rubs the two sides of the blade of the cutting blade 11 again, and the repeated friction can keep the two sides of the blade of the cutting blade 11 always flat and sharp, and can accurately cut along the preset cutting line, so that the fabric cut each time has a high degree of consistency and accuracy in size and shape, greatly improving the quality and qualified rate of the product, especially for those high-performance protective fabrics with strict requirements on size and shape, accurate cutting is very important, and the sharp cutting blade 11 can cut the fabric cleanly, so that the cutting edge is neat and smooth, without burrs or drawing.The fiber structure of the fabric will not be excessively damaged by cutting, and the original physical properties and protective functions of the fabric are maintained. At the same time, the neat cutting edge is also convenient for subsequent sewing, splicing and other processing procedures, improving the efficiency and quality of the entire production process. The wear on both sides of the cutting blade 11 can be repaired in time by the grinding groove block 809 cyclically rubbing the cutting blade 11, so that the cutting blade 11 can be kept in good working condition, thereby extending the service life of the cutting blade 11, thereby eliminating the need to frequently replace the new cutting blade 11, reducing the cost of purchasing the cutting blade 11, and reducing the tool cost in the production process. At the same time, since the generation of defective products and waste products caused by the wear of the cutting blade 11 is reduced, the waste of raw materials is also reduced to a certain extent, further saving production costs;

[0065] Since the two groups of cleaning rollers 814 are respectively arranged on both sides of the cutting blade 11, when the grinding sleeve 808 slides horizontally, two of the cleaning rollers 814 are respectively pressed against the two sides of the cutting blade 11. When the cleaning rollers 814 pass the two sides of the cutting blade 11, the thickness of the cutting blade 11 causes the fixing frame 813, the cleaning rollers 814 and the movable rod 811 to move away from the cutting blade 11. The compression force of the compression spring 3 816 can make the cleaning rollers 814 fit tightly against the two sides of the cutting blade 11. When the cleaning rollers 814 move on the cutting blade 11, the cleaning rollers 814 are pressed against the two sides of the cutting blade 11. When the cutting blade 11 is on both sides, the debris generated by the friction of the cutting blade 11 surface and the fabric debris and silk thread adhered when the fabric is cut can be removed by wiping with the cleaning roller 814, and the debris and silk thread adhered on both sides of the cutting blade 11 can be removed again by the grinding sleeve 808 when it is reset, and the debris and silk thread adhered on both sides of the cutting blade 11 can be removed when the cutting blade 11 slides down and does not conflict with the fabric, and when the cutting blade 11 slides up, the debris and silk thread adhered on both sides of the cutting blade 11 can be removed again by resetting the grinding sleeve 808 and the cleaning roller 814. The removal is performed when the cutting blade 11 is not working. The cutting blade 11 will not remove the debris and threads adhered to the two sides of the cutting blade 11 during the fabric cutting process, so that this operation can be performed when not working and stopped when working. The debris and threads can be removed without affecting the fabric cutting process. After the debris and threads are removed, the remaining debris and threads can be prevented from being pressed into the fabric during the cutting process, thereby avoiding affecting the appearance and quality of the fabric. For high-performance protective fabrics, these minor defects will seriously affect their protection. Performance and use function, so it can fundamentally eliminate the influence of external factors on the protective performance and use function of the fabric, and remove the debris and silk threads adhering to both sides of the cutting blade 11 through the cleaning roller 814 cycle, which can reduce the cutting problems caused by the contamination of the cutting blade 11, reduce the frequency and time of equipment downtime, and enable the cutting work to be carried out continuously and stably, thereby greatly improving the production efficiency. At the same time, since the defective products and waste products caused by cutting quality problems are reduced, the stability and reliability of the production process are further improved, and the delivery cycle and quality stability of the product are guaranteed;

[0066] At the same time, the staff electrically controls the extension of the telescopic shaft of the micro-electric gas rod 905 through the controller to push the connecting plate 906 fixedly connected thereto to move, and the movement of the connecting plate 906 drives the adjusting gear 907 rotatably connected thereto to move to a meshing state with the moving rack 902. At this time, the telescopic shaft of the hydraulic rod 5 starts to shrink and drives the fixed plate 6 to slide up, and the sliding of the fixed plate 6 drives the extension plate 901 fixedly connected thereto to slide up, and the sliding of the extension plate 901 drives the limiting sliding sleeve 911 slidably connected thereto to slide up on the outer wall of the limiting rod 910. The upward sliding of the limiting sleeve 911 drives the movable rack 902 fixedly connected thereto to slide upward, and the upward sliding of the movable rack 902 drives the adjusting gear 907 meshing therewith to rotate, and the rotation of the adjusting gear 907 drives the rotating shaft 904 to rotate through the blocking force generated by the cross-shaped limiting convex strip 909 and the limiting through groove 908, and the rotation of the rotating shaft 904 drives the two rotating rods 903 to rotate synchronously through the belt, and the rotation of the rotating rod 903 drives the conveying roller 2 fixedly connected thereto to rotate synchronously, and the rotation of the two conveying rollers 2 can move the transmission belt 3 on the surface Transmission, the transmission of the transmission belt 3 can move the cloth on the surface of the transmission belt 3 to a fixed position, and when the telescopic shaft of the hydraulic rod 5 drives the fixed plate 6 to extend and slide down, the telescopic shaft of the micro-electric gas rod 905 is in a retracted state, and the adjustment gear 907 and the movable rack 902 can be separated by the contraction of the telescopic shaft of the micro-electric gas rod 905, and the transmission belt 3 is in a stopped state, and the fabric is accurately loaded during the sliding of the fixed plate 6. Since the loading action is triggered at a specific moment when the cutting blade 11 slides up, precise action synchronization is achieved between the two. This synchronous control can ensure that the timing and position of each loading are very accurate, so that the fabric can be accurately transported to the cutting position, avoiding cutting errors and waste caused by inaccurate loading. Since the loading action cooperates with the action of the cutting blade 11, when a cutting cycle is completed, the new fabric is ready and can be immediately cut for the next time. This continuous and uninterrupted production method reduces the waiting time and idle time in the production process, and maximizes the utilization rate and production capacity of the equipment.
