Description

Technical Field

[0001] This invention relates to the field of face mask processing technology, and in particular to an integrated fabric cutting and feeding device. Background Technology

[0002] Car seats generally consist of a surface cover, internal foam, frame, adjustment device, and body connecting parts. The surface cover covers the internal foam and frame. After the car seat is installed, the surface cover comes into direct contact with the user, and its quality directly affects the user's experience.

[0003] The production process of car seat covers mainly includes main materials and auxiliary materials. The main materials are various cut pieces that form the external shape and structure of the car seat. The auxiliary materials are used to directly sew and connect the cut pieces, giving the cover its basic shape and making it more sturdy. They also facilitate the connection of the cover to foam and the frame. For example, sewing armrest groove fasteners to non-woven fabric, sewing J-shaped plastic parts to elastic bands, sewing skirt plastic parts to elastic bands, etc. In traditional sewing processes, the sewing between the material pieces (various plastic auxiliary materials) and the cut pieces is highly dependent on manual labor, resulting in low processing efficiency. For example, after fancy sewing technology became more mature, CNC templates were used for sewing. The cut pieces and material pieces were fixed on the template, and the machine performed the sewing operation. However, due to the short stitches, the machine constantly backstitches and trims the thread. After each operation, manual operation is required to feed and retrieve the material, which wastes time and has low sewing efficiency.

[0004] In related technologies, Chinese Patent No. CN206986468U discloses an automatic sewing device suitable for J-shaped plastic parts, including an industrial sewing machine. This industrial sewing machine includes a platform and a sewing machine body, with the sewing machine body mounted on the platform's surface. A feeding mechanism and a sewing auxiliary mechanism are provided on the platform. The sewing auxiliary mechanism includes a rotary hook cover and auxiliary components located on one side of the rotary hook cover. The feeding mechanism is used to feed J-shaped plastic parts and cut pieces to the rotary hook cover in groups. With this structure, automatic feeding can be achieved through the feeding mechanism, and the sewing auxiliary mechanism, in conjunction with the sewing machine body, can automatically sew the J-shaped plastic parts and cut pieces together. However, in the above sewing device, it is necessary to manually place the plastic parts and cut pieces side-by-side in groups into the second receiving space of the feeding guide plate. As sewing progresses, the feeding situation needs to be constantly monitored to replenish the plastic parts and cut pieces. This requires at least one operator for each sewing device, leading to increased labor costs.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the present invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an integrated fabric cutting and feeding device that realizes the automatic cutting, fabric preparation, positioning, feeding and sewing of cut pieces and fabric sheets, thereby reducing production costs.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: an integrated fabric cutting and feeding device, comprising:

[0008] The cutting mechanism cuts the fabric roll at equal intervals to form cut pieces;

[0009] The feeding mechanism stores and places the feed sheets;

[0010] The feeding mechanism receives the cut pieces and the sheet material, aligns the cut pieces and the sheet material according to their relative positions to form a sheet assembly, and conveys the obtained sheet assembly sequentially by means of friction.

[0011] A sewing mechanism sews the sheet assembly at a designated position after it has been conveyed to the position.

[0012] The traction mechanism sequentially pulls the sheet assembly to the needle drop position of the sewing mechanism, and fixes the relative position of the sheet and the cut piece as the sewing progresses.

[0013] Furthermore, the feeding mechanism includes a frame and a material blocking assembly, a material lifting assembly, and a material transferring assembly disposed on the frame;

[0014] The frame includes a tray, a base plate, and a support frame. The tray is located between the outlets of the cutting mechanism and the spring material mechanism, and sequentially receives the cut sheet and the material sheet. The base plate is set on a horizontal plane, and the support frame fixes and supports the base plate. The base plate has a gap on the side facing the output end of the cutting mechanism to accommodate the tray.

[0015] The top feeding assembly is disposed on the support frame and is correspondingly disposed to the pallet. The bottom blocking assembly is disposed on the support frame and is correspondingly disposed to the gap formed between the substrate and the pallet. It reciprocates along a horizontal plane perpendicular to the substrate. The transfer assembly is disposed on the substrate and reciprocates along the conveying direction of the sheet assembly.

[0016] Furthermore, the top material assembly includes an adjusting plate, a claw, a first top material cylinder, a second top material cylinder, a second intermediate plate, and a limiting block;

[0017] The adjusting plate is located on the side of the pallet facing the support frame. The first top-loading cylinder is fixed on the second intermediate plate and its output end is connected to the adjusting plate. The second top-loading cylinder is slidably connected to the frame and its output end is connected to the second intermediate plate. The first top-loading cylinder and the second top-loading cylinder are arranged perpendicular to each other. The limiting block is fixed on the base plate and is arranged at the end of the pallet opposite to the cutting mechanism and is correspondingly arranged to the pallet.

[0018] The pallet is provided with multiple adjustment slots perpendicular to the moving direction of the sheet assembly. The adjustment plate is provided with a claw at one end near the pallet. After the sheet falls onto the pallet, the claw passes through the adjustment slots and pushes the sheet toward the limiting block until the sheet abuts against the limiting block.

[0019] Furthermore, the top material assembly includes a rotating base, a drive rod, and an adapter;

[0020] The rotating seat is mounted on the support frame, the adapter is fixed to the side of the pallet away from the spring material mechanism, the drive rod is rotatably mounted on the rotating seat, and its output end is rotatably connected to the adapter.

[0021] The pallet is bent at one end opposite to the cutting mechanism to form an L-shaped structure. The drive rod drives the pallet so that the end of the pallet connects with the discharge end of the cutting mechanism to receive the cut piece. During the process of the drive rod driving the pallet back to the initial position, the pallet receives the material from the spring material mechanism and abuts against the L-shaped structure as the pallet tilts toward the side where the L-shaped structure is located.

[0022] Furthermore, the material blocking assembly is provided in two sets, located on both sides of the pallet respectively. Each set of the material blocking assembly includes a material blocking plate, a first material blocking cylinder, a second material blocking cylinder and a first intermediate plate.

[0023] The baffle plate is configured to correspond to the gap formed by the base plate and the support plate. The first baffle cylinder is fixed on the first intermediate plate and its output end is connected to the baffle plate. The second baffle cylinder is fixed on the support frame and its output end is connected to the first intermediate plate. The first baffle cylinder and the second baffle cylinder are configured to be perpendicular to each other.

[0024] After the pallet receives the cut piece and the sheet material, the baffle moves up until it is positioned between the pallet and the base plate, fitting against the two side walls of the pallet to restrict the relative position of the cut piece and the sheet material with respect to the pallet.

[0025] Furthermore, the material transfer assembly includes a slide table and a material transfer cylinder. The slide table is fixed on the substrate and is arranged along the conveying direction of the sheet assembly in the length direction. The material transfer cylinder is arranged facing the sheet assembly and is slidably disposed on the slide table.

[0026] After the sheet and the cut piece are aligned to form the sheet assembly, the output end of the transfer cylinder extends out to press the sheet assembly toward the substrate and move it along the length direction of the slide table. Friction is generated between the sheet assembly, the transfer cylinder, and the substrate to realize the transfer of the sheet assembly.

[0027] Furthermore, the material feeding mechanism includes a material storage box, a mounting plate, a feeding assembly, and a moving assembly;

[0028] The storage box is vertically fixed on the mounting plate on the side facing the cutting mechanism and located above the feeding mechanism. The material sheets are stacked sequentially in the storage box.

[0029] The material pushing assembly is located at the outlet of the storage box and includes: a material pushing plate and a material pushing cylinder. The material pushing plate blocks the outlet of the storage box, and the output end of the material pushing cylinder is connected to the material pushing plate. When the material pushing plate moves, it pushes the material sheet near the outlet in the storage box toward the tray and falls along a parabola onto the cut piece on the tray.

[0030] The movable component is located on the side of the mounting plate opposite to the storage box, and slides the mounting plate to the frame. It includes a movable cylinder, a movable slide rail, a movable slider, a connecting plate, and a fixed plate. The fixed plate is mounted on the frame and is parallel to the mounting plate. The movable cylinder is mounted on the fixed plate. The connecting plate is located between the fixed plate and the mounting plate, with one end fixedly connected to the mounting plate and the other end connected to the output end of the movable cylinder. The movable slide rail and the movable slider are located between the mounting plate and the fixed plate, respectively fixed to the mounting plate and the fixed plate. The movable slide rail is vertically arranged, and the movable slider is slidably connected to the movable slide rail. The movable cylinder drives the mounting plate to move along the length of the movable slide rail, changing the height position of the storage box.

[0031] Furthermore, the pusher plate includes a first step and a second step formed on the side facing the outlet of the storage box, which are adapted to the shape of the material sheet. A height difference is formed between the first step and the second step, and the height difference is less than the thickness of the material sheet. The first step blocks the outlet of the storage box. With the action of the pusher cylinder, the first step moves the material sheet above the tray, and the second step blocks the outlet of the storage box. As the pusher cylinder moves in the opposite direction, the material sheet on the first step falls vertically onto the cut piece on the tray, and the first step blocks the outlet of the storage box again.

[0032] Furthermore, the sewing mechanism includes a worktable and a sewing machine installed on one side of the worktable. The table surface of the worktable is coplanar with the plane where the base plate is located. The traction mechanism is located on the worktable and includes a pressing plate, a second adapter plate, a pressing cylinder, a traction motor, a traction slide rail, a traction slider, a sensing plate, and a sensor.

[0033] The traction slide rail is fixed on the worktable and is arranged parallel to the sewing direction of the sewing machine. The traction slider is slidably connected to the traction slide rail. The second adapter plate is fixed on the traction slider. The pressing plate is located on the side of the traction slider facing the sewing machine. The pressing cylinder is fixed on the second adapter plate and its output end is connected to the pressing plate. The sensing plate is located on the side of the traction slider away from the sewing machine. The sensors are located at the extreme positions at both ends of the traction slide rail.

[0034] After the material transfer assembly transfers the sheet assembly to the worktable surface, the pressing cylinder drives the pressing plate to move toward the plane of the worktable to press the sheet assembly onto the worktable. The traction motor drives the second adapter plate to move, causing friction between the sheet assembly, the pressing plate, and the worktable. As the sheet assembly is pulled to the needle drop position of the sewing machine, the sewing machine sews and fixes the sheet assembly at a designated position.

[0035] The present invention also provides a method of using the integrated fabric cutting and feeding device as described above, comprising the following steps:

[0036] The cutting mechanism cuts the fabric roll at equal intervals to form cut pieces, which are then conveyed to the feeding mechanism.

[0037] The material release mechanism releases the material sheet onto the cut sheet of the feeding mechanism;

[0038] The feeding mechanism aligns the cut pieces and fabric pieces according to their relative positions to form a sheet assembly, and the sheet assembly obtained by friction is conveyed sequentially along the sewing direction;

[0039] The traction mechanism pulls the closest piece assembly to the needle drop position of the sewing mechanism;

[0040] The sewing mechanism, in conjunction with the traction mechanism, stitches and fixes the sheet assembly at designated locations.

[0041] The beneficial effects of this invention are as follows: By integrating the cutting mechanism, elastic material mechanism, feeding mechanism, sewing mechanism, and traction mechanism into a single device, this invention eliminates the need for manual alignment of the fabric pieces and cut pieces, and can automatically realize the processes of cutting, positioning, feeding, and sewing of the fabric pieces and cut pieces, thereby reducing production costs and improving production efficiency.

[0060] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0062] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0063] like Figures 1 to 19 The fabric cutting and feeding integrated equipment shown includes:

[0064] The cutting mechanism 10 cuts the fabric roll at equal intervals to form cut pieces 01;

[0065] Feed mechanism 20 stores and places feed sheet 02;

[0066] The feeding mechanism 30 receives the cut piece 01 and the material piece 02, aligns the cut piece 01 and the material piece 02 according to their relative positions to form a sheet assembly, and conveys the obtained sheet assembly sequentially by means of friction.

[0067] Sewing mechanism 40 sews the designated position on the conveyed sheet assembly;

[0068] The traction mechanism 50 sequentially pulls the sheet assembly to the needle drop position of the sewing mechanism 40, and fixes the relative position of the sheet 02 and the cut piece 01 as the sewing progresses.

[0069] This invention integrates the cutting mechanism 10, the elastic material mechanism 20, the feeding mechanism 30, the sewing mechanism 40, and the traction mechanism 50 into a single device. It eliminates the need for manual alignment of the material piece 02 and the cut piece 01, and can automatically realize the process of cutting, positioning, feeding, and sewing the cut piece 01 and the material piece 02, thereby reducing production costs and improving production efficiency.

[0070] Based on the above embodiments, the feeding mechanism 30 includes a frame 34 and a material blocking assembly 31, a material lifting assembly 32 and a material transferring assembly 33 disposed on the frame 34;

[0071] The frame 34 includes a tray 341, a base plate 342 and a support frame 343. The tray 341 is located between the outlet of the cutting mechanism 10 and the spring material mechanism 20, and sequentially receives the cut piece 01 and the material piece 02. The base plate 342 is set on a horizontal plane. The support frame 343 fixes and supports the base plate 342, and the side of the base plate 342 facing the output end of the cutting mechanism 10 has a gap to accommodate the tray 341.

[0072] The top feeding assembly 32 is mounted on the support frame 343 and is correspondingly mounted to the pallet 341. The bottom feeding assembly 31 is mounted on the support frame 343 and is correspondingly mounted to the gap formed between the substrate 342 and the pallet 341. It reciprocates along the horizontal plane perpendicular to the substrate 342. The transfer assembly 33 is mounted on the substrate 342 and reciprocates along the conveying direction of the sheet assembly.

[0073] It should be noted that the top material assembly 32 acts on the material piece 02, restricting the relative position of the material piece 02 in the direction perpendicular to the sewing direction, so that the ends of the material piece 02 and the cut piece 01 can be aligned; the bottom material assembly 31 acts on the cut piece 01, restricting the relative position of the cut piece 01 and the material piece 02 in the direction parallel to the sewing direction, so that the two sides of the material piece 02 and the cut piece 01 can be aligned, thereby realizing the alignment process of the material piece 02 and the cut piece 01 in two directions, forming a piece assembly, thus avoiding manual alignment and greatly saving labor.

[0074] The feeding mechanism 30 uses friction to sequentially convey the sheet assembly formed by the cut piece 01 and the material piece 02. Since the surfaces of the cut piece 01 and the material piece 02 are relatively rough while the surface of the substrate 342 is relatively smooth, the friction between the cut piece 01 and the material piece 02, as well as the friction between the transfer component 33 and the sheet assembly, is greater than the friction between the sheet assembly and the substrate 342. This allows the transfer component 33 to move the formed sheet assembly to the designated position through friction without causing misalignment between the cut piece 01 and the material piece 02. In addition, both the cut piece 01 and the material piece 02 have a certain degree of hardness, preventing them from curling or jamming due to friction during the transfer process, effectively ensuring the normal operation of the feeding mechanism 30.

[0075] The sewing mechanism 40 includes a workbench 41 and a sewing machine 42 installed on one side of the workbench 41. The table surface of the workbench 41 is coplanar with the plane of the base plate 342. The tape cutting mechanism 10 includes a tape cutting platform and at least two tape cutting machines. The two tape cutting machines can work simultaneously. An elastic material mechanism 20, a feeding mechanism 30, a sewing mechanism 40, and a traction mechanism 50 are additionally provided in the directions of both sides, so that both sides can work at the same time without the need to set up an additional frame 34, which makes reasonable use of the workspace and improves production efficiency.

[0076] In addition, the structure of the tape cutting machine and sewing machine 42 is not specifically set here. It is a fully automatic tape cutting machine and sewing machine 42 commonly used in the prior art, which can realize the functions of equidistant tape cutting and automatic sewing.

[0077] Based on the above embodiments, the top material assembly 32 includes an adjustment plate 321, a claw 321a, a first top material cylinder 322, a second top material cylinder 323, a second intermediate plate 324, and a limiting block 325;

[0078] The adjusting plate 321 is located on the side of the pallet 341 facing the support frame 343. The first top-feeding cylinder 322 is fixed on the second intermediate plate 324, and its output end is connected to the adjusting plate 321. The second top-feeding cylinder 323 is slidably connected to the frame 34, and its output end is connected to the second intermediate plate 324. The first top-feeding cylinder 322 and the second top-feeding cylinder 323 are arranged perpendicular to each other. The limiting block 325 is fixed on the base plate 342 and is set at the end of the pallet 341 opposite to the cutting mechanism 10, and is correspondingly set to the pallet 341. That is, the first top-feeding cylinder 322 controls the adjusting plate 321 to move along the height direction, and the second top-feeding cylinder 323 controls the adjusting plate 321 to move along the feeding direction of the cut piece 01, that is, controls the movement in the left and right directions.

[0079] The tray 341 is provided with multiple adjustment grooves 341a perpendicular to the moving direction of the sheet assembly. The adjustment plate 321 is provided with a claw 321a at one end near the tray 341. After the sheet 02 falls onto the tray 341, the claw 321a passes through the adjustment grooves 341a and pushes the sheet 02 toward the limiting block 325 until the sheet 02 abuts against the limiting block 325.

[0080] When the cut piece 01 on the support plate 341 receives the material piece 02 from the elastic material mechanism 20, the relative position between the cut piece 01 and the material piece 02 is not accurate. The second top material cylinder 323 controls the claw 321a of the adjusting plate 321 to move into the adjusting groove 341a, and the end face of the claw 321a is slightly higher than the upper plane of the support plate 341. At this time, the first top material cylinder 322 is activated, so that the claw 321a can oscillate the material piece 02 and move towards the limiting block 325 until the material piece 02 abuts against the limiting block 325, thus completing the positioning function of the material piece 02 and the cut piece 01 in the direction perpendicular to the sewing direction, ensuring the accuracy of their relative positions in this direction.

[0081] It should be noted that although the tray 341 in this manner is located in the gap on the side of the substrate 342 facing the output end of the cutting mechanism 10, in order to ensure the support performance of the tray 341 and the parallelism between the tray 341 and the substrate 342, and to ensure that the sheet assembly can be smoothly transferred by friction, the tray 341 and the substrate 342 can be connected by partial fixation. That is, gaps are left on both sides of the substrate 342 and the tray 341 for the material blocking assembly 31 to move, and the remaining positions are fixedly connected.

[0082] As another embodiment of the top material assembly 32, the top material assembly 32 includes a rotating seat 326, a drive rod 327 and an adapter 328;

[0083] The rotating seat 326 is mounted on the support frame 343. The adapter 328 is fixed to the side of the pallet 341 away from the material feeding mechanism 20. The drive rod 327 is rotatably mounted on the rotating seat 326, and its output end is rotatably connected to the adapter 328.

[0084] The end of the pallet 341 opposite to the cutting mechanism 10 is bent to form an L-shaped structure 341b. The drive rod 327 drives the pallet 341 so that the end of the pallet 341 connects with the discharge end of the cutting mechanism 10 to receive the cut piece 01. During the process of the drive rod 327 driving the pallet 341 back to the initial position, it receives the material piece 02 from the spring material mechanism 20 and abuts against the L-shaped structure 341b as the pallet 341 tilts toward the side where the L-shaped structure 341b is located.

[0085] Through the connection of the adapter 328, when the drive rod 327 extends, it will drive the tray 341 to move towards the cutting mechanism 10, so that the tray 341 can dock with the cutting mechanism 10. The cut piece 01 cut by the cutting mechanism 10 will be placed directly on the tray 341. During the retraction of the drive rod 327, due to the rotatable connection between the adapter 328 and the drive rod 327, the drive rod 327 will drive the tray 341 to rotate, forming a certain angle with respect to the base plate 342. At this time, under the action of the spring material mechanism 20, the material piece 02 falls onto the cut piece 01 on the tray 341. Under the action of the tilt angle, the material piece 02 will naturally slide towards the bent end of the tray 341 and abut against the L-shaped structure 341b, completing the positioning of the material piece 02 and the cut piece 01 in the direction perpendicular to the sewing direction, ensuring the accuracy of their relative positions in this direction.

[0086] It should be noted that this configuration requires the partial movement and relative rotation of the support plate 341 to be realized. Therefore, the substrate 342 and the support plate 341 are completely separated. The supporting function of the support plate 341 depends entirely on the top material assembly 32. The gap formed by the substrate 342 is sufficient to provide space for the support plate 341 to move and rotate. During the reset process of the support plate 341, when the L-shaped structure 341b and the substrate 342 form a complete fit, that is, when the support plate 341 returns to its initial position, the support plate 341 is parallel to the substrate 342, thereby ensuring that subsequent actions can be carried out normally and smoothly.

[0087] Based on the above embodiments, two sets of material blocking components 31 are provided, located on both sides of the pallet 341 respectively. Each set of material blocking components 31 includes a material blocking plate 311, a first material blocking cylinder 312, a second material blocking cylinder 313 and a first intermediate plate 314.

[0088] The baffle plate 311 is configured to correspond to the gap formed by the substrate 342 and the support plate 341. The first baffle cylinder 312 is fixed on the first intermediate plate 314 and its output end is connected to the baffle plate 311. The second baffle cylinder 313 is fixed on the support frame 343 and its output end is connected to the first intermediate plate 314. The first baffle cylinder 312 and the second baffle cylinder 313 are arranged perpendicular to each other. That is, the first baffle cylinder 312 changes the position of the baffle plate 311 in the sheet assembly conveying direction, that is, the position in the front and back direction, and the second baffle cylinder 313 changes the position of the baffle plate 311 in the height direction.

[0089] After the tray 341 receives the cut piece 01 and the material piece 02, the baffle plate 311 moves upward until it is located between the tray 341 and the base plate 342, and is fitted against the two side walls of the tray 341 to restrict the relative position of the cut piece 01 and the material piece 02 with the tray 341.

[0090] Once the relative positions of the material piece 02 and the cut piece 01 in the direction perpendicular to the sewing direction are defined, the second stop cylinder 313 first drives the first intermediate plate 314 to move upward, which in turn drives the first stop cylinder 312 and the stop plate 311 to move upward as a whole, so that the stop plate 311 is located between the support plate 341 and the base plate 342. The end of the support plate 341 is set higher than the upper plane of the base plate 342. At this time, the first stop cylinder 312 drives the stop plate 311 to move toward the side wall of the support plate 341, so that the stop plate 311 can push the material piece 02 and the cut piece 01 to move. The positions of the two side edges are aligned with the two sides of the stop plate 311, which realizes the position definition in the direction parallel to the sewing direction, so that the material piece 02 and the cut piece 01 can form a sheet assembly, ensuring the accuracy of the relative position between the two during sewing.

[0091] Based on the above embodiments, the material transfer assembly 33 includes a slide table 331 and a material transfer cylinder 332. The slide table 331 is fixed on the substrate 342 and is arranged along the conveying direction of the sheet assembly in the length direction. The material transfer cylinder 332 is arranged facing the sheet assembly and is slidably arranged on the slide table 331.

[0092] After the sheet 02 and the cut sheet 01 are aligned to form a sheet assembly, the output end of the transfer cylinder 332 extends out to press the sheet assembly toward the substrate 342 and move it along the length direction of the slide table 331. Friction is generated between the sheet assembly, the transfer cylinder 332 and the substrate 342 to realize the transfer of the sheet assembly.

[0093] After the sheet material 02 and the cut piece 01 are aligned to form a sheet assembly, the stop assembly 31 resets and moves to below the base plate 342. At this time, the slide table 331 controls the moving cylinder 24a to move to the corresponding position on the support plate 341, above the sheet assembly. The moving cylinder 24a extends, applying pressure to the sheet assembly, causing the sheet assembly to press against the support plate 341 and the base plate 342. As the slide table 331 drives the moving cylinder 24a to reset, friction will be generated between the moving cylinder 24a and the sheet assembly, between the sheet material 02 and the cut piece 01, and between the sheet assembly and the base plate 342. The frictional force and the frictional force between the transfer cylinder 332 and the sheet assembly are greater than the frictional force between the sheet assembly and the substrate 342. This allows the sheet assembly to move along the length of the slide table 331 towards the side where the sewing mechanism 40 is located, following the transfer cylinder 332. When it reaches the designated position, the transfer cylinder 332 retracts and moves away, completing the sheet assembly transfer process. During this process, the accuracy of the relative position between the sheet 02 and the cut piece 01 can be effectively guaranteed, avoiding the separation and misalignment of the sheet 02 and the cut piece 01, and ensuring that subsequent processes can proceed smoothly.

[0094] Based on the above embodiments, the feeding mechanism 20 includes a storage box 21, a mounting plate 22, a feeding assembly 23, and a moving assembly 24;

[0095] The storage box 21 is vertically fixed on the mounting plate 22 on the side facing the cutting mechanism 10, and is located above the feeding mechanism 30. The material sheets 02 are stacked in the storage box 21 in sequence.

[0096] The material pushing assembly 23 is located at the outlet of the storage box 21 and includes: a material pushing plate 231 and a material pushing cylinder 232. The material pushing plate 231 blocks the outlet of the storage box 21, and the output end of the material pushing cylinder 232 is connected to the material pushing plate 231. When the material pushing plate 231 is activated, it pushes the material piece 02 near the outlet in the storage box 21 toward the support plate 341 and falls along a parabola onto the cut piece 01 on the support plate 341.

[0097] The moving component 24 is located on the side of the mounting plate 22 away from the storage box 21, and slides the mounting plate 22 to the frame 34. It includes: a moving cylinder 24a, a moving slide rail 24b, a moving slider 24c, a connecting plate 24d, and a fixed plate 24e. The fixed plate 24e is set on the frame 34 and is parallel to the mounting plate 22. The moving cylinder 24a is mounted on the fixed plate 24e. The connecting plate 24d is located between the fixed plate 24e and the mounting plate 22, with one end fixedly connected to the mounting plate 22 and the other end connected to the output end of the moving cylinder 24a. The moving slide rail 24b and the moving slider 24c are located between the mounting plate 22 and the fixed plate 24e, and are fixed on the mounting plate 22 and the fixed plate 24e respectively. The moving slide rail 24b is vertically set, and the moving slider 24c is slidably connected to the moving slide rail 24b. The moving cylinder 24a drives the mounting plate 22 to move along the length direction of the moving slide rail 24b, changing the height position of the storage box 21.

[0098] Since the storage box 21 is vertically arranged, the material pieces 02 are stacked in the storage box 21. A gap is left at the outlet position of the storage box 21 for the pusher cylinder 232 to operate. When the pusher cylinder 232 drives the pusher plate 231 to move out of the outlet of the storage box 21, the bottom material piece 02 is thrown out of the outlet by the force of the pusher plate 231 and falls onto the cut piece 01 located on the support plate 341. At the same time, since the pusher plate 231 will block the outlet of the storage box 21 after it is pushed out, it will prevent the material piece 02 above from falling out of the outlet. With the reset action of the pusher plate 231, the material piece 02 above moves to the outlet position and abuts against the end of the pusher plate 231, and enters the pushing process of the next material piece 02.

[0099] It should be noted that, in order to prevent the sheet 02 from falling directly onto the substrate 342 after entering the discharge port, a receiving plate needs to be set at the discharge port. This ensures that the sheet 02 entering the discharge port will only change its falling direction under the action of gravity when pushed by the pusher plate 231, so that the sheet 02 can fall precisely onto the cut piece 01 located on the support plate 341 after being pushed out, thus ensuring the accuracy of the falling position.

[0100] Before the feeding component 23 starts working, the mounting plate 22 can be driven by the moving cylinder 24a, so that the mounting plate 22 moves the storage box 21 and the feeding component 23 along the length of the moving slide rail 24b, changing the overall height of the storage box 21 and the feeding component 23, ensuring that after the feeding plate 231 moves, the material piece 02 can fall accurately onto the tray 341, ensuring the accuracy of the material piece 02 falling; when the material piece 02 in the storage box 21 is used up, the entire storage box 21 can also be lowered by the moving component 24, making it easier to replenish the material piece 02 in the storage box 21.

[0101] As a preferred embodiment of the above embodiment, the pusher plate 231 includes a first step portion 231a and a second step portion 231b formed on the side facing the outlet of the storage box 21, which are adapted to the shape of the sheet 02. A height difference is formed between the first step portion 231a and the second step portion 231b, and the height difference is less than the thickness of the sheet 02. The first step portion 231a blocks the outlet of the storage box 21. With the action of the pusher cylinder 232, the first step portion 231a drives the sheet 02 to move above the support plate 341, and the second step portion 231b blocks the outlet of the storage box 21. As the pusher cylinder 232 moves in the opposite direction, the sheet 02 on the first step portion 231a falls vertically onto the cut sheet 01 of the support plate 341, and the first step portion 231a blocks the outlet of the storage box 21 again.

[0102] By forming a first step 231a and a second step 231b on the pusher plate 231, an additional receiving plate is avoided at the bottom of the storage box 21 to receive the sheet 02. When the pusher cylinder 232 is not activated, the first step 231a is positioned precisely at the outlet of the storage box 21, blocking the outlet and preventing the storage box 21 from falling onto the substrate 342. When the pusher cylinder 232 pushes the pusher plate 231 toward the side of the support plate 341, the height difference between the first step 231a and the second step 231b causes the end of the second step 231b to act on the sheet 02. Under the support of the first step 231a, the sheet 02 is moved directly above the support plate 341. Simultaneously, the second step 231b blocks the next sheet 02. 31b forms a contact action, preventing the next piece 02 from directly entering the discharge port position; at this time, the pusher cylinder 232 retracts, and both the first step 231a and the second step 231b return to their initial positions. Due to the removal of the first step 231a, the piece 02 displaced on the first step 231a falls directly onto the cut piece 01 on the support plate 341 under the action of gravity, simplifying the path of the piece 02 falling. Under the action of the height difference between the first step 231a and the second step 231b, with the reset action of the first step 231a, the next piece 02 will enter the discharge port position and contact the first step 231a, and its end will abut against the second step 231b, entering the pushing process of the next piece 02; so that the pusher plate 231 has the effect of pushing and supporting at the same time, and can also further improve the accuracy of the falling position of the piece 02.

[0103] Based on the above embodiments, the traction mechanism 50 is located on the workbench 41 and includes a pressing plate 51, a second adapter plate 52, a pressing cylinder 53, a traction motor 54, a traction slide rail 55, a traction slider 56, a sensing plate 57, and a sensor 58.

[0104] The traction slide rail 55 is fixed on the worktable 41 and is set parallel to the sewing direction of the sewing machine 42. The traction slider 56 is slidably connected to the traction slide rail 55. The second adapter plate 52 is fixed on the traction slider 56. The pressing plate 51 is located on the side of the traction slider 56 facing the sewing machine 42. The pressing cylinder 53 is fixed on the second adapter plate 52 and its output end is connected to the pressing plate 51. The sensing plate 57 is located on the side of the traction slider 56 away from the sewing machine 42. The sensors 58 are located at the extreme positions at both ends of the traction slide rail 55.

[0105] After the transfer assembly 33 transfers the sheet assembly to the worktable 41, the pressing cylinder 53 drives the pressing plate 51 to move toward the plane of the worktable 41 to press the sheet assembly onto the worktable 41. The traction motor 54 drives the second adapter plate 52 to move, so that friction is generated between the sheet assembly, the pressing plate 51 and the worktable 41. At the same time, the sheet assembly is pulled to the needle drop position of the sewing machine 42, and the sewing machine 42 sews and fixes the sheet assembly at the designated position.

[0106] After the material transfer mechanism successfully transfers the sheet assembly to the designated position, the traction cylinder drives the pressing plate 51 to move toward the end where the sheet assembly is located until the sensing plate 57 contacts the sensor 58 at this end. At this time, the pressing plate 51 is just above the sheet assembly. The pressing cylinder 53 drives the pressing plate 51 to apply a certain pressure to the sheet assembly, thereby creating friction between the pressing plate 51 and the sheet assembly. Under the action of the traction cylinder, the pressing plate 51 is moved along the length of the traction slide rail 55, gradually moving the sheet assembly to the needle drop position of the sewing mechanism 40. As the sewing progresses, the relative positions of the material sheet 02 and the cut piece 01 are fixed to ensure the accuracy of positioning during the sewing process. When the sheet assembly is sewn, the sensing plate 57 is just in contact with the sensor 58 at the other end. At this time, the traction cylinder returns to the initial position and repeats the above steps to form a continuous sewing process.

[0107] like Figure 20 As shown, the present invention also provides a method of using the integrated fabric cutting and feeding device as described above, comprising the following steps:

[0108] The cutting mechanism 10 cuts the fabric rolls at equal intervals to form cut pieces 01, which are then conveyed to the feeding mechanism 30.

[0109] The material feeding mechanism 20 releases the material sheet 02 onto the cut piece 01 of the feeding mechanism 30;

[0110] The feeding mechanism 30 aligns the cut piece 01 and the material piece 02 according to their relative positions to form a sheet assembly, and the sheet assembly obtained by friction is sequentially conveyed along the sewing direction;

[0111] The traction mechanism 50 pulls the closest piece assembly to the needle drop position of the sewing mechanism 40;

[0112] The sewing mechanism 40, along with the action of the traction mechanism 50, sews and fixes the sheet assembly at a designated position.

[0113] The technical effects achieved by the operation of this method are the same as those in the above embodiments, and will not be repeated here.
