Description

Technical Field

[0001] The present invention relates to the technical field of fabric processing equipment, and particularly relates to a continuous fabric laying and cutting device. Background Art

[0002] Spreading fabrics into multiple layers and cutting them into required sizes is usually an essential step in the fabric production process. In the actual production process, it can be spread and cut layer by layer and then stacked, that is, laying one layer and cutting the end once, but this is likely to cause misalignment between the ends and sides of each layer of fabric, and the end cutting is frequent, which causes great damage to the machine and affects the processing efficiency. More waste is likely to occur when uniformly cutting the sides of the fabric subsequently. It is also possible to use a fabric laying machine to reciprocally lay the fabric in an S shape and finally uniformly cut the ends and sides of multiple layers of fabric. However, during the fabric laying process, the reversing position of the fabric needs to be fixed for each layer, otherwise the fabric ends will be uneven and wrinkles are likely to occur between adjacent layers of fabric, affecting the dimensions in the length direction of the fabric. However, the operation of fixing the ends of each layer is rather troublesome and also affects the production efficiency. In addition, whether it is single-layer spreading or reciprocal spreading by the fabric laying machine, the handling of the trimmed waste and the discharging of multiple layers of fabric require manual operations, which not only has a large manual labor intensity but also easily causes fabric misalignment during the discharging process. Summary of the Invention

[0003] The purpose of the present invention is to provide a continuous fabric laying and cutting device, which can ensure the neatness of each layer of fabric while realizing the reciprocating spreading and stacking of the fabric. At the same time, it is convenient for cutting the ends and sides of multiple layers of fabric, automatically collects waste and discharges multiple layers of fabric, effectively reduces the manual labor intensity, improves the production efficiency, ensures the quality of fabric laying and cutting, and reduces fabric waste.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions:

[0005] A continuous fabric laying and cutting device includes a frame and a fabric laying mechanism. The fabric laying mechanism is arranged along the width direction of the frame and slides along the length direction of the frame. A fabric supporting plate arranged along the length direction of the frame is detachably installed on the frame. At two diagonal corners of one group of the frame, there are respectively provided cooperating fabric supporting mechanisms, and at both ends of the frame, there are respectively provided cutting mechanisms cooperating with the adjacent fabric supporting mechanisms.

[0006] The fabric laying mechanism includes fabric laying legs vertically arranged on both sides of the frame. Between the two fabric laying legs, a fabric laying roller, several fabric guiding rollers, and several ironing rollers arranged along the width direction of the frame are positioned and rotatably installed. A fabric roll is installed on the fabric laying roller. A fabric clamping mechanism that slides along the length direction of the frame is provided on the frame. A cutting component is provided on the fabric clamping mechanism. The movable end of the fabric roll bypasses several fabric guiding rollers and ironing rollers in an S shape and is fixed by the fabric clamping mechanism. After the fabric roll is spread to the required number of layers, the fabric clamping mechanism fixes the cutting position, and the cutting component cuts the fabric roll. An edge trimming component is also installed between the fabric laying legs. On each side of the two fabric laying legs away from each other, a side receiving component cooperating with the corresponding edge trimming component is provided.

[0007] The fabric supporting mechanism includes fabric supporting frames vertically arranged at a corner side of the frame. The fabric supporting frames in the two fabric supporting mechanisms are located between the two fabric laying legs and slide along the length direction of the frame. Several horizontally arranged fabric supporting rods are sequentially provided on the fabric supporting frames from top to bottom. One end of the fabric supporting rod close to the fabric supporting frame is eccentrically rotatably installed on the fabric supporting frame. The rotation axes of several fabric supporting rods are coaxial and vertically arranged. In the normal state, the fabric supporting rods are arranged along the length direction of the frame, and the end of the fabric supporting rod away from the corresponding fabric supporting frame is close to the other end of the frame. The several fabric supporting rods in the two fabric supporting mechanisms are arranged at intervals. During operation, several fabric supporting rods in the two fabric supporting mechanisms alternately rotate eccentrically around the corresponding fabric supporting frames from bottom to top to be arranged along the width direction of the frame in sequence.

[0008] By adopting the above technical solution, at the beginning, the fabric laying mechanism is located at one end of the frame. The fabric roll is installed on the fabric laying roller. The movable end of the fabric roll bypasses several fabric guiding rollers and ironing rollers in an S shape and is fixed by the fabric clamping mechanism. The fabric clamping mechanism slides along the length direction of the frame, driving the movable end of the fabric roll to move to the end of the frame away from the fabric laying mechanism, and laying the first layer of fabric on the fabric receiving plate. The fabric supporting rod in the fabric supporting mechanism close to the fabric laying mechanism, which is located above the fabric receiving plate and closest to the first layer of fabric, rotates eccentrically from the state along the length direction of the frame to the state along the width direction of the frame, and clamps one end of the first layer of fabric close to the fabric laying mechanism.

[0009] The fabric laying legs drive the whole fabric laying mechanism to slide along the length direction of the frame to the other end of the frame, and lay the second layer of fabric with the fabric supporting rod starting to work at the starting end as the commutation limit. At this time, the fabric supporting rod in the fabric supporting mechanism close to the fabric laying mechanism, which is located above the second layer of fabric and closest to it, rotates eccentrically from the state along the length direction of the frame to the state along the width direction of the frame, and clamps one end of the second layer of fabric close to the fabric laying mechanism. And so on. The reciprocating sliding of the fabric laying mechanism along the length direction of the frame cooperates with the sequential alternate rotation of several fabric supporting rods in the two fabric supporting mechanisms from bottom to top to the state of being arranged along the width direction of the frame, and several layers of fabric are laid flat and neatly with the fabric supporting rods in the working state at both ends as the commutation.

[0010] During the process of unwinding the cloth roll, the ironing roller irons the cloth to prevent the cloth from curling and forming wrinkles when changing from the curled state to the flat state, ensuring the neatness of the flat-laid cloth. The edge trimming component performs side trimming on the cloth, making the flat-laid cloth the required width. In this way, there is no need to perform edge trimming on the length direction of several layers of cloth. Single-layer trimming can improve accuracy, reduce waste, and reduce frayed edges compared to multi-layer trimming. In addition, the side waste materials cut by the edge trimming component are collected by two sets of edge receiving components respectively, eliminating the need for manual handling and preventing the side waste materials from affecting the normal material laying of the material laying mechanism.

[0011] When the cloth roll is spread to the required number of layers, the cloth clamping mechanism releases the fixation of the movable end of the cloth and moves to the required cutting position of the cloth to fix it. The cutting component is used to cut the cloth to form a new movable end. The slitting mechanisms at both ends work respectively to cut off the ends of several layers of cloth, forming several layers of independent cloth. By removing the cloth supporting plate from the frame, removing several layers of independent cloth on the cloth supporting plate, and reinstalling the cloth supporting plate, it is possible to avoid disturbing the laid cloth.

[0012] By setting up a material laying mechanism, a cloth supporting mechanism, a slitting mechanism, a cloth clamping mechanism, a cutting component, an edge trimming component, an edge receiving component, etc. that cooperate with each other, the present invention realizes the reciprocating spreading and stacking of the cloth while ensuring the neatness of each layer of cloth. At the same time, it is convenient for cutting the ends and sides of multiple layers of cloth, automatically realizes the collection of waste materials and the blanking of multiple layers of cloth, effectively reduces the labor intensity of workers, improves production efficiency, ensures the quality of cloth spreading and cutting, reduces cloth waste, and can also meet the processing requirements of cloth with different length requirements, effectively improving the scope of application.

[0013] Furthermore, the slitting mechanism includes a slitting frame arranged along the width direction of the frame and sliding along the length direction of the frame. A vertically arranged slitting knife is provided on the slitting frame, and the slitting knives in the two sets of slitting mechanisms are located on the side where the two slitting frames are close to each other; a pressing plate arranged along the length direction of the slitting frame is provided on the side of the slitting frame close to the slitting knife. The pressing plate is vertically slidably installed on the slitting frame, and a relief groove arranged along the length direction of the pressing plate and cooperating with the slitting knife is further provided on the pressing plate. The slitting knife is limited and slidably installed in the corresponding relief groove along the length direction of the relief groove.

[0014] By adopting the above technical solution, when the slitting mechanism works after the cloth roll is spread to the required number of layers, the two slitting frames slide along the length direction of the frame and approach the corresponding cloth supporting mechanisms. The two pressing plates are located on the side where the cloth supporting rods at both ends of the cloth are close to each other. The pressing plates slide vertically downward to press the cloth, and the slitting knives slide along the length direction of the relief groove from the end of the cloth supporting rod away from the cloth supporting frame in the corresponding working state to cut off the ends of several layers of cloth, realizing the automatic cutting process of the ends of multiple layers of cloth.

[0015] Furthermore, a material collecting cavity is provided inside the cloth supporting rod along its length direction and penetrates through one end of the cloth supporting rod away from the corresponding cloth supporting frame. A feeding port is provided on the side wall of the cloth supporting rod along its length direction and is communicated with the material collecting cavity. When the cloth supporting rod rotates to work along the width direction of the machine frame, the feeding ports on the working cloth supporting rods in the two groups of cloth supporting mechanisms are located on the sides away from each other. On the side of the cutting frame away from the pressing plate, a material pushing frame is provided which slides along the length direction of the machine frame. A plurality of layers of material pushing sheets are arranged on the material pushing frame. The plurality of material pushing sheets are arranged along the length direction of the cutting frame and are in one-to-one correspondence and cooperation with the feeding ports on the working cloth supporting rod close to them.

[0016] By adopting the above technical solution, when the cutting mechanism works, the pressing plate is used to press multiple layers of cloth, and the material pushing frame is driven to drive a plurality of material pushing sheets to move integrally close to the corresponding working cloth supporting rod. The cloth outside the cloth supporting rod is pressed by the corresponding material pushing sheet against the feeding port on the outer wall of the corresponding cloth supporting rod. After the cutting knife cuts off the ends of the multiple layers of cloth, the material pushing frame drives a plurality of material pushing sheets to move and stuff the cut-off end waste outside the corresponding cloth supporting rod into the material collecting cavity from the feeding port, avoiding the loose dropping of the end waste and facilitating the subsequent centralized treatment of the end waste.

[0017] Furthermore, material collecting mechanisms corresponding to the two groups of cloth supporting mechanisms are respectively provided on both sides of the machine frame. The mutually cooperating cloth supporting mechanism and material collecting mechanism are located at the same end of the machine frame and are respectively located on both sides of the machine frame. The material collecting mechanism includes a material collecting box provided on one side of the machine frame. A plurality of layers of material suction ports are provided on the side wall of the material collecting box close to the machine frame from top to bottom. The plurality of material suction ports are in one-to-one correspondence and cooperation with the ends of the cloth supporting rods close to them. The material collecting box slides along the width direction of the machine frame and is connected with a material collecting fan.

[0018] By adopting the above technical solution, after the cutting mechanism completes the cutting work, the whole material collecting box moves towards the direction close to the machine frame, so that a plurality of material suction ports on its side wall are inserted into the ends of the corresponding working cloth supporting rods. The material collecting cavity of the cloth supporting rod is communicated with the material collecting box through the material suction port. The material collecting fan works to suck the end waste in the material collecting cavities on a plurality of cloth supporting rods into the material collecting box, realizing the rapid collection of the end waste, without manual treatment and avoiding the scattering of the end waste. After the material collection is completed, the material collecting box can be reset.

[0019] Further, there are two sets of pressing mechanisms sliding along the length direction of the machine frame between the two sets of slitting mechanisms. The pressing mechanism includes a pressing frame sliding along the length direction of the machine frame. An extrusion roller with an axis arranged along the width direction of the machine frame is provided on the pressing frame. Pressing seats vertically slidably installed on the pressing frame are provided at both ends of the extrusion roller, and both ends of the extrusion roller are rotatably installed on the pressing seats in a positioned manner; when the cloth laying mechanism works, the two sets of slitting mechanisms and the pressing mechanisms are in pairs and approach both ends of the machine frame respectively, and the two sets of cloth supporting mechanisms are located between the two sets of pressing mechanisms; before the cloth laying mechanism finishes working and the slitting mechanism starts to work, the two sets of pressing mechanisms slide synchronously from the middle position of the machine frame to both ends of the machine frame, and the extrusion roller works to press and smooth the cloth.

[0020] By adopting the above technical solution, before the cloth laying mechanism finishes laying multiple layers of cloth and the slitting mechanism starts to work, the two sets of pressing mechanisms move to the middle position of the multiple layers of cloth. The pressing seats drive the extrusion roller to move vertically downward, and the multiple layers of cloth are compacted by the extrusion roller. Then, the two pressing frames slide away from each other as a whole, and the extrusion roller moves and is rotatably installed in a positioned manner along with the pressing frame, so as to realize pressing and smoothing the multiple layers of cloth, and avoid the middle position of the multiple layers of cloth from being loose due to the gap between the cloth supporting rods at both ends, which affects the control accuracy of the length of the cloth in the length direction when slitting the end part subsequently.

[0021] Further, the cloth clamping mechanism includes a cloth clamping frame sliding along the length direction of the machine frame. A cloth clamping plate arranged along the width direction of the machine frame and vertically slidably installed on the cloth clamping frame is provided on the cloth clamping frame. Cloth clamping seats sliding along the length direction of the cloth clamping plate are provided at the bottoms of both ends of the cloth clamping plate; cloth clamping shafts arranged along the length direction of the cloth clamping plate are rotatably installed on the sides of the two cloth clamping seats close to each other respectively. There are at least two groups of cloth clamping shafts along the length direction of the machine frame on each cloth clamping shaft on each cloth clamping seat, and each group has two cloth clamping shafts that can slide relatively up and down; a plurality of cloth clamping beads arranged in a circumferential array are embedded on the outer wall of each cloth clamping shaft, and the plurality of cloth clamping beads on the two cloth clamping shafts in each group are arranged in a staggered manner;

[0022] The cutting assembly includes a cutting seat slidably installed on the cloth clamping plate along the length direction of the cloth clamping plate. The cutting seat is located between the two cloth clamping seats. A vertically arranged cutting knife is vertically slidably installed on the cutting seat, and cloth clamping shafts are provided on both sides of the cutting knife along the length direction of the cloth clamping plate.

[0023] By adopting the above technical solution, before the fabric laying mechanism starts to work, the distance between the cloth clamping seats at both ends of the cloth clamping plate is adjusted according to the width of the cloth roll after being trimmed on both sides, and the two sides of the movable end of the cloth roll are clamped on a plurality of cloth clamping shafts on the corresponding cloth clamping seats, so as to realize the clamping and fixing of the movable end of the cloth roll. The whole cloth clamping plate slides vertically and the cloth clamping frame slides along the length direction of the machine frame towards one end away from the fabric laying mechanism, driving the movable end of the cloth roll to move to lay the first layer of fabric flat on the fabric receiving plate. After the fabric laying mechanism finishes working, the cloth clamping seats slide away from each other so that the cloth clamping shafts disengage from the movable end of the fabric. The whole cloth clamping plate moves vertically upward to a height where the cloth clamping shafts are in cooperation with the position to be cut of the fabric. The whole cloth clamping frame moves to be in cooperation with the position to be cut of the fabric. The cloth clamping seats slide close to each other and the two cloth clamping shafts in each group adjust their positions by relative vertical sliding, so that the side edges of the fabric are clamped between the corresponding cloth clamping shafts from both sides of the position to be cut of the fabric, realizing the side fixing of the position to be cut of the fabric. The cutting knife slides vertically downward in cooperation with the sliding of the cutting seat along the length direction of the cloth clamping plate, and the cutting knife cuts the fabric between the cloth clamping shafts on both sides of the cloth clamping plate, and ensures that the new movable end of the fabric can still be fixed by the cloth clamping shafts without repeated operation. Among them, cloth clamping beads are embedded on the outer wall of the cloth clamping shaft, and a plurality of cloth clamping beads on the two upper and lower cloth clamping shafts in each group are arranged in a staggered manner, ensuring the clamping and fixing effect on the side edge of the fabric and preventing the end of the fabric from disengaging between the cloth clamping shafts during the moving process.

[0024] Furthermore, both ends of the fabric receiving plate are provided with end fixing grooves which are arranged along its length direction and penetrate through it up and down. Sliding grooves which are arranged along its length direction and communicate with it are provided on the inner side walls of the two end fixing grooves. End fixing plates which are arranged along its length direction and slide along the length direction of the machine frame are respectively arranged in the two sliding grooves; A tension spring which is arranged along its sliding direction is connected between the mutually remote sides of the two end fixing plates and the corresponding sliding grooves, and a plurality of tension springs are arranged in an array along the length direction of the end fixing plates; Electromagnetic sheets which are arranged along its length direction and cooperate with each other are embedded on the mutually close side walls of the two end fixing plates. When the electromagnetic sheets are electrified, the mutually close sides of the two end fixing plates are adsorbed to each other in the end fixing grooves, and the mutually remote sides are located in the corresponding sliding grooves. When the electromagnetic sheets are powered off, the two end fixing plates are completely located in the corresponding sliding grooves under the action of the corresponding tension springs.

[0025] By adopting the above technical solution, when the cloth clamping mechanism drives the movable end of the first layer of cloth to move to one end of the rack far away from the cloth laying mechanism, the movable end of the cloth is taken off and placed into the end fixing groove. The electromagnetic sheet is powered on, and the two end fixing plates are used to clamp the movable end of the cloth. In this way, the cloth clamping mechanism can move to the side of the end fixing groove far away from the cloth laying mechanism, which is convenient for the subsequent cloth clamping mechanism to move to the cutting position to work after the cloth is laid to the required number of layers, and avoids affecting the neatness of the multi-layer cloth that has been laid flat when the cloth clamping mechanism always fixes the movable end of the first layer of cloth and then works. After the end part of the multi-layer cloth is cut, the electromagnetic sheet is powered off, the fixation of the electromagnetic sheet on the movable end of the first layer of cloth is released, and the end waste at this place can be taken off from below the end fixing groove.

[0026] Further, on the inner side walls of both sides of the rack, there are respectively provided discharge guide rails arranged along the length direction thereof and with openings facing each other. The two sides of the cloth bearing plate are installed in the corresponding discharge guide rails in a limited sliding manner along the length direction thereof. On the side wall of the cloth bearing plate, there is provided a discharge rack arranged along the length direction thereof. In the discharge guide rails, there are rotatably installed at both ends of the discharge rack and engaged with the discharge rack discharge gears; at one end of the rack, there is provided an inlet plate guide rail arranged along the length direction thereof and communicated with the discharge guide rails. Between the two inlet plate guide rails, there is also provided a cloth bearing plate. The two cloth bearing plates have the same structure, and the mutually close ends thereof are embedded with mutually cooperating electromagnetic adsorption strips; the discharge guide rails and the inlet plate guide rails are synchronously and vertically slidably installed on the rack.

[0027] By adopting the above technical solution, there are two cloth bearing plates arranged before and after along the length direction of the rack. The cloth bearing plate installed in the discharge guide rail is in the working state. After the cloth on it is laid and cut, the discharge guide rails and the inlet plate guide rails synchronously move vertically downward, and through the rotation of the discharge gears and the engagement with the discharge rack, it is realized to drive the cloth bearing plate to slide along the discharge guide rail, move out the cloth bearing plate and the multi-layer independent cloth, and realize the neat blanking of the cloth. At the same time, the electromagnetic adsorption strips are powered on to connect the two cloth bearing plates. Through the discharge sliding of the cloth bearing plate between the discharge guide rails, the cloth bearing plate between the inlet plate guide rails is driven to slide into the discharge guide rails until the cloth bearing plate for discharging completely slides out. The electromagnetic adsorption strips are powered off, the two cloth bearing plates are separated, and the discharge guide rails and the inlet plate guide rails synchronously slide upward to reset. The cloth bearing plate remaining in the discharge guide rails continues to work, and another cloth bearing plate can be installed in the inlet plate guide rails as a backup. In this way, the two front and rear cloth bearing plates work alternately, which is not only convenient for the quick and neat blanking of multi-layer independent cloth, but also convenient for ensuring the continuity of the cloth laying and cutting work.

[0028] Further, at the bottom of the cloth supporting rod, there is provided a receiving groove arranged along the length direction thereof. In the receiving groove, there is rotatably installed a smoothing roller arranged along the length direction of the cloth supporting rod. The rotation axis of the smoothing roller is located in the receiving groove, and the bottom of the smoothing roller is located outside the receiving groove.

[0029] By adopting the above technical solution, the smoothing roller is installed at the bottom of the cloth supporting rod through the accommodating groove. In this way, during the process of the cloth supporting rod eccentrically rotating from the state along the length direction of the machine frame to the state along the width direction of the machine frame for work, the smoothing roller is used to roll and smooth the corresponding cloth of each layer, further avoiding the generation of wrinkles in each layer of cloth and improving the neatness of the cloth spreading.

[0030] Further, each trimming component includes an adjusting rod connected between the two cloth spreading legs and arranged along the length direction of the machine frame. The two ends of the adjusting rod are respectively provided with trimming seats that slide synchronously and in opposite directions along its length direction. Symmetrically arranged folding members are respectively provided on the two trimming seats; the two folding members are in a right trapezoidal structure, the side away from each other is the hypotenuse, and the length of the end close to the feeding end is greater than the length of the end close to the discharging end;

[0031] The folding member includes a telescopic short rod, a telescopic long rod, a fixed rod and a telescopic inclined rod. The two ends of the fixed rod are respectively perpendicular and fixedly connected to the telescopic short rod and the telescopic long rod at the ends close to it; the two ends of the telescopic inclined rod are hinged to the ends of the telescopic short rod and the telescopic long rod away from the fixed rod, and its hinge axis is perpendicular to the telescopic short rod and the fixed rod. The central position of the telescopic inclined rod is hinged to the trimming seat, and its hinge axis is parallel to its hinge axis with the telescopic short rod and is connected with a micro motor for driving its rotation;

[0032] On one side of each trimming seat close to the telescopic short rod, a trimming scissors is arranged along the length direction of the adjusting rod. The trimming scissors is located on the side of the telescopic short rod away from the telescopic long rod, and the trimming scissors is slidably installed on the trimming seat along its length direction.

[0033] By adopting the above technical solution, both sides of the cloth released from the cloth roll are side-folded by the folding members using the hypotenuse of the folding members. The trimming scissors cut the folded sides at the discharging position of the folding members, and the cut sides are collected by the edge closing component. Among them, the folding member includes structures such as a telescopic short rod, a telescopic long rod, a fixed rod and a telescopic inclined rod. The telescopic inclined rod can be driven to rotate by a micro motor, driving the telescopic inclined rod to cooperate with the telescopic short rod and the telescopic long rod for linkage, realizing the adjustment of the inclination angle of the telescopic inclined rod, thereby realizing different folding amplitudes of the sides and meeting the trimming requirements of sides with different widths, effectively improving the scope of application.

The movable end of the fabric roll 24 bypasses a plurality of fabric guiding rollers 22 and ironing rollers 23 in an S shape and is fixed by the fabric clamping mechanism 05. After the fabric roll 24 is spread to the required number of layers, the fabric clamping mechanism 05 fixes the cutting position, and the cutting assembly 55 cuts the fabric roll 24. In addition, a trimming assembly 03 is installed between the fabric laying legs 2, and on the mutually remote sides of the two fabric laying legs 2, there are respectively provided edge collecting assemblies 04 cooperating with the corresponding trimming assemblies 03.

[0051] As Figure 1 and Figure 2 shown in the figure, the fabric laying mechanism 02 realizes multi-layer continuous spreading of the fabric through reciprocating movement along the length direction of the frame 01. During the process of fabric release, the ironing rollers 23 perform ironing treatment on the fabric to reduce fabric wrinkles and prevent the fabric from curling during spreading. The trimming assembly 03 trims the side edges of the fabric before the fabric is conveyed for spreading, cuts it into the required width before the fabric is spread and stacked, and uses the edge collecting assemblies 04 to collect the cut side waste materials. In this way, single-layer cutting can improve accuracy, reduce waste, and reduce frayed edges compared to multi-layer cutting.

[0052] Specifically, as Figure 2As shown in the figure, the edge trimming assembly 03 includes an adjustment rod 3 connected between two fabric laying legs 2 and arranged along the length direction of the frame 01. At both ends of the adjustment rod 3, there are edge trimming seats 31 that slide synchronously and in opposite directions along its length direction. On the two edge trimming seats 31, there are symmetrically arranged folding members 32. The two folding members 32 are in the shape of a right trapezoid, with the hypotenuse on the side away from each other, and the length of the end closer to the feeding end is greater than the length of the end closer to the discharging end. On one side of each edge trimming seat 31 close to the discharging end of the folding member 32, there is a trimming scissors 38 arranged along the length direction of the adjustment rod 3, and the trimming scissors 38 is slidably installed on the edge trimming seat 31 along its length direction.

[0053] As Figure 2 shown in the figure, the two sides of the fabric released from the fabric roll 24 pass through the folding members 32 and are side-folded using the hypotenuse of the folding members 32. The trimming scissors 38 cut the folded sides at the discharging position of the folding members 32, and the cut sides are collected by the edge collecting assembly 04. Among them, the two edge trimming seats 31 can drive the folding members 32 to slide along the length direction of the adjustment rod 3, so as to adjust the distance between the two folding members 32 and meet the side cutting requirements of fabrics with different widths.

[0054] To further improve the scope of application, in this embodiment, as Figure 2 shown in the figure, the folding member 32 includes a telescopic short rod 33, a telescopic long rod 34, a fixed rod 35, and a telescopic inclined rod 36. At both ends of the fixed rod 35, it is vertically and fixedly connected to the telescopic short rod 33 and the telescopic long rod 34 close to it. The two ends of the telescopic inclined rod 36 are hinged to the ends of the telescopic short rod 33 and the telescopic long rod 34 away from the fixed rod 35, and its hinge axis is perpendicular to the telescopic short rod 33 and the fixed rod 35. The center position of the telescopic inclined rod 36 is hinged to the edge trimming seat 31, and its hinge axis is parallel to its hinge axis with the telescopic short rod 33 and is connected with a micro motor 37 that drives its rotation. By driving the telescopic inclined rod 36 to rotate through the micro motor 37, the telescopic inclined rod 36 is driven to cooperate with the telescopic short rod 33 and the telescopic long rod 34 to realize the adjustment of the inclination angle of the telescopic inclined rod 36, so as to realize different folding amplitudes of the sides and meet the side cutting requirements of different widths.

[0055] In this embodiment, as Figure 2 shown in the figure, the edge collecting assembly 04 includes an edge collecting shaft 4 with a vertical axis. The lower end of the edge collecting shaft 4 is rotatably installed on the fabric laying leg 2 around its axis; a coaxial edge collecting cylinder 41 is detachably installed outside the edge collecting shaft 4, and a limiting disk 42 for limiting the edge collecting cylinder 41 is detachably installed at the upper end of the edge collecting shaft 4. The side waste is wound on the edge collecting cylinder 41. A reversing shaft 43 cooperating with the edge collecting shaft 4 is also arranged on the fabric laying leg 2 to reverse the side waste, so that the side waste can be neatly wound on the edge collecting cylinder.

[0056] As Figure 1 andFigure 3 As shown, the cloth clamping mechanism 05 includes a cloth clamping frame 5 that slides along the length direction of the frame 01. A cloth clamping plate 51 is provided on the cloth clamping frame 5 and is vertically slidably installed on the cloth clamping frame 5 along the width direction of the frame 01. Cloth clamping seats 52 that slide along the length direction thereof are provided at the bottoms of both ends of the cloth clamping plate 51. On one side of the two cloth clamping seats 52 close to each other, cloth clamping shafts 53 arranged along the length direction of the cloth clamping plate 51 are respectively positioned and rotatably installed. As Figure 1 and Figure 4 shown, on each cloth clamping seat 52, there are at least two groups of cloth clamping shafts 53 arranged along the length direction of the frame 01, and each group has two that can slide relatively up and down.

[0057] As Figure 1 、 Figure 3 and Figure 4 shown, before the cloth laying mechanism 02 starts working, the distance between the cloth clamping seats 52 at both ends of the cloth clamping plate 51 is adjusted according to the width of the cloth roll 24 after being trimmed on both sides. The two sides of the movable end of the cloth roll 24 are clamped on multiple groups of cloth clamping shafts 53 on the corresponding cloth clamping seats 52, realizing the clamping and fixing of the movable end of the cloth roll 24. The whole cloth clamping plate 51 slides vertically and the cloth clamping frame 5 slides along the length direction of the frame 01 towards the end far from the cloth laying mechanism 02, driving the movable end of the cloth roll 24 to move to lay the first layer of cloth flat on the cloth receiving plate 1. Among them, as Figure 1 and Figure 4 shown, a number of cloth clamping beads 54 arranged in a circumferential array are embedded on the outer wall of each cloth clamping shaft 53, and the cloth clamping beads 54 on the two cloth clamping shafts 53 in each group are arranged in a staggered manner, using the number of cloth clamping beads 54 to improve the stability of clamping the side edge of the cloth.

[0058] As Figure 1 and Figure 3 shown, the cloth supporting mechanism 06 includes a cloth supporting frame 6 vertically arranged on one corner side of the frame 01. A number of horizontally arranged cloth supporting rods 61 are successively provided on the cloth supporting frame 6 from top to bottom. One end of the cloth supporting rod 61 close to the cloth supporting frame 6 is eccentrically rotatably installed on the cloth supporting frame 6, and the rotation axes of the number of cloth supporting rods 61 are coaxial and vertically arranged. As Figure 3 and Figure 5 shown, the number of cloth supporting rods 61 in the two groups of cloth supporting mechanisms 06 are arranged at intervals. In the normal state, the cloth supporting rods 61 are arranged along the length direction of the frame 01 and the end of the cloth supporting rod 61 far from the corresponding cloth supporting frame 6 is close to the other end of the frame 01. During work, the number of cloth supporting rods 61 in the two groups of cloth supporting mechanisms 06 alternately rotate eccentrically around the corresponding cloth supporting frame 6 from bottom to top in turn to be arranged along the width direction of the frame 01.

[0059] As Figure 1 and Figure 3As shown in the figure, at the beginning, the cloth laying mechanism 02 is located at one end of the frame 01. The cloth roll 24 is installed on the cloth laying roller 21. The movable end of the cloth roll 24 bypasses a number of cloth guiding rollers 22 and the ironing roller 23 in an S shape and is fixed by the cloth clamping mechanism 05. The cloth clamping mechanism 05 slides along the length direction of the frame 01, driving the movable end of the cloth roll 24 to move to the end of the frame 01 far from the cloth laying mechanism 02, and laying the first layer of cloth on the cloth receiving plate 1. In the edge supporting mechanism near the cloth laying mechanism 02, the cloth supporting rod 61 located above the cloth receiving plate 1 and closest to the first layer of cloth eccentrically rotates from the state along the length direction of the frame 01 to the state along the width direction of the frame 01 and clamps at one end of the first layer of cloth near the cloth laying mechanism 02.

[0060] As Figure 1 and Figure 3 shown, the cloth laying support leg 2 drives the whole cloth laying mechanism 02 to slide along the length direction of the frame 01 to the other end of the frame 01, and lays the second layer of cloth with the cloth supporting rod 61 working at the starting end as the commutation limit. At this time, the cloth supporting rod 61 located above the second layer of cloth and closest to it in the edge supporting mechanism near the cloth laying mechanism 02 eccentrically rotates from the state along the length direction of the frame 01 to the state along the width direction of the frame 01 and clamps at one end of the second layer of cloth near the cloth laying mechanism 02. In this way, by reciprocating, the reciprocating sliding of the cloth laying mechanism 02 along the length direction of the frame 01 is matched with the sequential and alternating rotation of a number of cloth supporting rods 61 in the two groups of cloth supporting mechanisms 06 from bottom to top to the state set along the width direction of the frame 01, and several layers of cloth are laid flat neatly with the cloth supporting rods 61 at both ends in the working state as the commutation.

[0061] Among them, as Figure 3 or Figure 5 shown, the cloth supporting frames 6 in the two groups of cloth supporting mechanisms 06 are located between the two cloth laying support legs 2 and slide along the length direction of the frame 01, and the distance between the two groups of cloth supporting mechanisms 06 can be adjusted within a certain range to meet the requirements of spreading and stacking cloths of different lengths. Of course, if interference occurs with the eccentric rotation of the cloth supporting rod 61 after adjusting the distance between the two cloth supporting frames 6, cloth supporting rods 61 of other length specifications can be replaced to ensure the use requirements. In addition, as Figure 5 shown, a receiving groove 64 is provided at the bottom of the cloth supporting rod 61 along its length direction. A smoothing roller 65 arranged along the length direction of the cloth supporting rod 61 is rotatably installed in the receiving groove 64 in a positioned manner. The rotation axis of the smoothing roller 65 is located in the receiving groove 64, and the bottom of the smoothing roller 65 is located outside the receiving groove 64. In this way, during the process of the cloth supporting rod 61 eccentrically rotating from the state along the length direction of the frame 01 to the state along the width direction of the frame 01 for work, the smoothing roller 65 is used to roll and smooth each corresponding layer of cloth, further avoiding wrinkles on each layer of cloth and improving the neatness of cloth spreading.

[0062] As Figure 3 and Figure 4As shown, the cutting assembly 55 includes a cutting base 56 slidably mounted on the cloth clamping plate 51 along the length direction of the cloth clamping plate 51. The cutting base 56 is located between the two cloth clamping seats 52. A vertically arranged cutting knife 57 is slidably mounted on the cutting base 56 in the vertical direction, and cloth clamping shafts 53 are provided on both sides of the cutting knife 57 along the length direction of the cloth clamping plate 51. After the cloth laying mechanism 02 finishes working, the cloth clamping seats 52 slide away from each other so that the cloth clamping shafts 53 are disengaged from the movable end of the cloth. The whole cloth clamping plate 51 moves vertically upward until the cloth clamping shafts 53 are in height cooperation with the cloth to be cut. The cloth clamping frame 5 as a whole moves to cooperate with the cloth to be cut. The cloth clamping seats 52 slide closer to each other, and the two cloth clamping shafts 53 in each group adjust their positions by relative vertical sliding, so that the side edges of the cloth are clamped between the corresponding cloth clamping shafts 53 from both sides of the cloth to be cut, realizing the side fixing of the cloth to be cut. The cutting knife 57 slides vertically downward in cooperation with the sliding of the cutting base 56 along the length direction of the cloth clamping plate 51, and the cloth is cut by the cutting knife 57 between the cloth clamping shafts 53 on both sides of the cloth clamping plate 51, and it is ensured that the new movable end of the cloth can still be fixed by the cloth clamping shafts 53 without repeated operation.

[0063] As Figure 3 and Figure 6 shown, to avoid the case that the cloth clamping mechanism 05 always fixes the movable end of the first layer of cloth, which is likely to affect the neatness of the multi-layer cloth that has been laid flat during subsequent work, end fixing grooves 11 are provided at both ends of the cloth bearing plate 1 along its length direction and penetrate through it up and down. Slide grooves 12 are provided on the two inner side walls of the end fixing grooves 11 along their length direction and communicate with them. End fixing plates 13 are respectively provided in the two slide grooves 12 along their length direction and slide along the length direction of the frame 01. Tension springs 14 are connected between the mutually remote sides of the two end fixing plates 13 and the corresponding slide grooves 12 along their sliding direction, and a plurality of tension springs 14 are arranged in an array along the length direction of the end fixing plates 13. Electromagnetic sheets 15 are embedded in the mutually close side walls of the two end fixing plates 13 along their length direction and cooperate with each other. When the electromagnetic sheets 15 are energized, the mutually close sides of the two end fixing plates 13 are adsorbed to each other within the end fixing grooves 11, and the mutually remote sides are located within the corresponding slide grooves 12. When the electromagnetic sheets 15 are de-energized, the two end fixing plates 13 are completely located within the corresponding slide grooves 12 under the action of the corresponding tension springs 14.

[0064] As Figure 3 and Figure 6As shown, when the cloth clamping mechanism 05 drives the movable end of the first layer of cloth to move to the end of the frame 01 away from the cloth spreading mechanism 02, the movable end of the cloth is removed and placed in the end fixing groove 11, and the electromagnetic sheet 15 is energized, and the two end fixing plates 13 are used to clamp the movable end of the cloth, so that the cloth clamping mechanism 05 can be moved to the side of the end fixing groove 11 away from the cloth spreading mechanism 02, so that the subsequent cloth clamping mechanism 05 can move to the cutting position after the cloth is spread to the required number of layers. When the end of the multi-layer cloth is cut, the electromagnetic sheet 15 is de-energized, and the electromagnetic sheet 15 is released from the fixation of the movable end of the first layer of cloth, and the end waste at the bottom of the end fixing groove 11 can be removed.

[0065] like Figure 1 and Figure 5 As shown, two groups of squeezing mechanisms 08 sliding along the length direction of the frame 01 are provided between the two groups of cutting mechanisms 07. The squeezing mechanism 08 includes a squeezing frame 8 sliding along the length direction of the frame 01, and a squeezing roller 81 with an axis arranged along the width direction of the frame 01 is provided on the squeezing frame 8. The two ends of the squeezing roller 81 are provided with squeezing seats 82 vertically slidably mounted on the squeezing frame 8, and the two ends of the squeezing roller 81 are positioned and rotatably mounted on the squeezing seats 82. When the cloth spreading mechanism 02 is working, the two groups of cutting mechanisms 07 and squeezing mechanisms 08 are arranged in pairs close to the two ends of the frame 01, and the two groups of cloth supporting mechanisms 06 are located between the two groups of squeezing mechanisms 08.

[0066] like Figure 1 and Figure 5 As shown, when the spreading mechanism 02 completes the spreading of the multi-layer cloth and before the slitting mechanism 07 works, the two sets of squeezing mechanisms 08 move to the middle position of the multi-layer cloth, and the squeezing seat 82 drives the squeezing roller 81 to move vertically downward, and the squeezing roller 81 is used to compact the multi-layer cloth. Then the two squeezing frames 8 slide away from each other as a whole, and the squeezing roller 81 moves and rotates with the squeezing frame 8 to pressurize and smooth the multi-layer cloth, so as to avoid the multi-layer cloth from becoming loose in the middle position due to the gap between the cloth supporting rods 61 at both ends, which affects the control accuracy of the length direction of the cloth when the end is subsequently cut.

[0067] In this embodiment, if Figure 3 and Figure 5 As shown, the slitting mechanism 07 includes a slitting frame 7 arranged along the width direction of the frame 01 and sliding along the length direction of the frame 01, and a vertically arranged slitting knife 71 is provided on the slitting frame 7, and the slitting knives 71 in the two groups of slitting mechanisms 07 are located on the side where the two slitting frames 7 are close to each other. A pressing plate 72 arranged along the length direction of the slitting frame 7 is provided on the side close to the slitting knife 71, and the pressing plate 72 is vertically slidably mounted on the slitting frame 7, and a clearance groove 73 arranged along the length direction of the clearance groove 73 and cooperating with the slitting knife 71 is also provided on the pressing plate 72, and the slitting knife 71 is limitedly slidably mounted in the corresponding clearance groove 73 along the length direction of the clearance groove 73.

[0068] like Figure 3and Figure 5 As shown, when the cloth is spread to the required number of layers and is cut by the cutting assembly 55 and is pressurized and smoothed by the squeezing mechanism 08, the slitting mechanism 07 works, and the two slitting frames 7 slide along the length direction of the frame 01 and approach each other to the corresponding cloth-supporting mechanism 06, so that the two pressing plates 72 are located on the side where the cloth-supporting rods 61 at both ends of the cloth are close to each other, and the pressing plates 72 slide vertically downward to compact the cloth, and the slitting knife 71 slides along the length direction of the make way slot 73 from the end of the cloth-supporting rod 61 in the corresponding working state away from the cloth-supporting frame 6, and cuts off the ends of several layers of cloth, thereby realizing automatic cutting processing of the ends of multiple layers of cloth.

[0069] like Figure 3 and Figure 5 As shown, in order to facilitate the collection of waste materials at the end of multi-layer cloth, a receiving cavity 62 is provided in the cloth support rod 61 along its length direction and through its end away from the corresponding cloth support frame 6, and a feed port 63 is provided on the side wall of the cloth support rod 61 along its length direction and connected to the receiving cavity 62. When the cloth support rod 61 rotates to work along the width direction of the frame 01, the feed ports 63 on the cloth support rods 61 working in the two sets of cloth support mechanisms 06 are located on the side away from each other. A pusher rack 74 that slides along the length direction of the frame 01 is provided on the side of the slitting frame 7 away from the pressing plate 72, and a plurality of layers of pusher sheets 75 are provided on the pusher rack 74, and the plurality of pusher sheets 75 are provided along the length direction of the slitting frame 7 and correspond one-to-one with the feed ports 63 on the working cloth support rods 61 close to it.

[0070] like Figure 5 As shown, a material receiving mechanism 09 corresponding to the two sets of cloth-supporting mechanisms 06 is respectively provided on both sides of the frame 01, and the cloth-supporting mechanisms 06 and the material receiving mechanism 09 that cooperate with each other are located at the same end of the frame 01 and are respectively located on both sides of the frame 01. The material receiving mechanism 09 includes a material receiving box 9 provided on one side of the frame 01, and the material receiving box 9 is provided with a plurality of layers of suction ports 91 from top to bottom on the side wall close to the frame 01, and the plurality of suction ports 91 are matched one by one with the ends of the cloth-supporting rods 61 close thereto, and the material receiving box 9 slides along the width direction of the frame 01 and is connected with a material receiving fan 92.

[0071] like Figure 5As shown, when the slitting mechanism 07 is working, the pressing plate 72 is used to press the multi-layer fabric, and the pushing frame 74 is driven to drive a plurality of pushing sheets 75 to move as a whole close to the corresponding working fabric supporting rod 61. The fabric outside the fabric supporting rod 61 is pressed by the corresponding pushing sheet 75 against the feeding port 63 on the outer wall of the corresponding fabric supporting rod 61. At the same time, the receiving box 9 moves as a whole in the direction close to the frame 01, so that a plurality of suction ports 91 on its side wall are inserted into the ends of a plurality of corresponding working fabric supporting rods 61. The receiving cavity 62 of the fabric supporting rod 61 is communicated with the receiving box 9 through the suction port 91. After the slitting knife 71 cuts off the ends of the multi-layer fabric, the pushing frame 74 drives a plurality of pushing sheets 75 to move, and the cut-off end waste outside the corresponding fabric supporting rod 61 is stuffed into the receiving cavity 62 from the feeding port 63. The receiving air blower 92 works, and the end waste in the receiving cavity 62 on a plurality of fabric supporting rods 61 is sucked into the receiving box 9, realizing the rapid collection of the end waste, without manual treatment and avoiding the scattering of the end waste. After the receiving is completed, the receiving box 9 can be reset.

[0072] As Figure 5 and Figure 6 shown, for the convenience of the feeding of the multi-layer independent fabrics after the end slitting and to ensure the continuity of the fabric laying and cutting work, discharging guide rails 17 are respectively arranged on the inner side walls of the two sides of the frame 01 along its length direction and with opposite openings. The two sides of the fabric supporting plate 1 are installed in the corresponding discharging guide rails 17 in a limited sliding manner along its length direction. A discharging rack 16 is arranged on the side wall of the fabric supporting plate 1 along its length direction. Discharging gears 171 located at both ends of the discharging rack 16 and meshing with it are installed in the discharging guide rails 17 in a positioning and rotating manner. One end of the frame 01 is provided with a feeding guide rail 18 arranged along its length direction and communicated with the discharging guide rails 17, and the discharging guide rails 17 and the feeding guide rail 18 are synchronously and vertically slidably installed on the frame 01; a fabric supporting plate 1 is also arranged between the two feeding guide rails 18, and electromagnetic adsorption strips 19 which are matched with each other are embedded at the ends of the two fabric supporting plates 1 which are close to each other. Among them, in this embodiment, electromagnetic adsorption strips 19 are embedded at both ends of the fabric supporting plate 1, so that there is no need to distinguish the positions of both ends during installation and use.

[0073] As Figure 5 and Figure 6As shown in the figure, there are two cloth supporting plates 1 arranged front and back along the length direction of the frame 01 and working alternately. The cloth supporting plate 1 installed in the discharge guide rail 17 is in the working state. After the cloth on it is spread and cut, the discharge guide rail 17 and the feeding guide rail 18 slide downward synchronously, and through the rotation of the discharge gear 171 and the engagement with the discharge rack 16, the cloth supporting plate 1 is driven to slide along the discharge guide rail 17 and avoid interference with other structures, and the cloth supporting plate 1 and multiple layers of independent cloth are moved out to realize the neat blanking of the cloth. At the same time, the electromagnetic adsorption strip 19 is electrified to connect the two cloth supporting plates 1. Through the discharge sliding of the cloth supporting plate 1 between the discharge guide rails 17, the cloth supporting plate 1 between the feeding guide rails 18 is driven to slide into the discharge guide rail 17 until the discharging cloth supporting plate 1 completely slides out. The electromagnetic adsorption strip 19 is powered off, the two cloth supporting plates 1 are separated, and the discharge guide rail 17 and the feeding guide rail 18 slide upward synchronously to reset. The cloth supporting plate 1 remaining in the discharge guide rail 17 continues to work, and another cloth supporting plate 1 can be installed in the feeding guide rail 18 as a backup.

[0074] It should be noted that in the present invention, the rotations involved above are driven by structures such as motors and motor gears, the horizontal slides involved above are driven by screw structures or horizontal telescopic cylinders and other structures, and the vertical slides involved above are driven by screw structures, electromagnetic springs or vertical telescopic cylinders and other structures. Appropriate driving methods can be selected according to actual usage requirements to ensure that there is no interference between the structures. There is no need to elaborate too much in this embodiment, and only simple illustrations are shown in the figure.

[0075] The working principle and usage method of the present invention:

[0076] The clamping mechanism 05 is used to drive the movable end of the cloth to move to one end of the frame 01 away from the cloth laying mechanism 02, and the movable end of the cloth is fixed in the end fixing groove 11 of the cloth supporting plate 1. The cloth laying mechanism 02 realizes the multi-layer continuous spreading of the cloth through the reciprocating movement along the length direction of the frame 01. The edge trimming assembly 03 trims the side edges of the cloth before the cloth is conveyed and spread, cuts it into the required width before the cloth is spread and stacked, and the edge collecting assembly 04 collects the side waste materials cut off. During the reciprocating movement of the cloth laying mechanism 02, several cloth supporting rods 61 in the two groups of cloth supporting mechanisms 06 are alternately rotated from bottom to top to the state of being arranged along the width direction of the frame 01 in sequence, and several layers of cloth are laid flat neatly with the cloth supporting rods 61 at both ends in the working state as the turning points.

[0077] When the fabric is spread to the required number of layers, the clamping mechanism 05 is used to clamp and fix the position of the fabric to be cut, and the cutting assembly 55 is used to cut the fabric. Moreover, the new movable end is still fixed by the clamping mechanism 05. The pressing mechanism 08 is used to press and smooth the multi-layer fabric to prevent the middle part of the multi-layer fabric from sagging due to the gap between the two end cloth-supporting rods 61. The slitting mechanism 07 works. The pressing plate 72 is used to compact both ends of the fabric, and the slitting knife 71 is used to cut the ends of several layers of fabric. The pushing frame 74 and the pushing piece 75 are used to push the cut end waste into the material collection cavity 62 of the cloth-supporting rod 61, and the material collection mechanism 09 is used to collect the end waste in the material collection cavity 62 into the material collection box 9. Finally, the fabric-bearing plate 1 is moved to take out the multi-layer independent fabric, realizing the neat blanking of the fabric, and other fabric-bearing plates 1 work alternately.

[0078] The above description shows and describes the preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the inventive concept described herein through the above teachings or the techniques or knowledge in related fields.
