[0048] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0049] Please see Figures 1 to 13 The present invention provides a fully automatic folding sewing machine, comprising a feeder 1, a folding machine 2, a transfer machine 3, and a sewing machine 4 arranged sequentially along the conveying direction;

[0050] The folding machine 2 includes a frame 21, a pressing and edge-trimming machine 22, a first folding machine 23, a material support 24, a pressing machine 25, a second folding machine 26, and a clamping plate 27;

[0051] The frame 21 is located between the feeder 1 and the transfer machine 3. The first folding machine 23 and the second folding machine 26 are slidably connected to the frame 21. The first folding machine 23 and the second folding machine 26 are arranged in sequence along the conveying direction. The first folding machine 23 and the second folding machine 26 fold the opposite sides of the fabric respectively.

[0052] The first folding machine 23 and the second folding machine 26 both include a mounting plate 2a, a rotary drive component 2b, a rotating plate 2c, an upper clamping plate 2d, a lower clamping plate 2e, and a clamping drive component 2f. The mounting plate 2a is slidably connected to the frame 21. The rotary drive component 2b is disposed on the mounting plate 2a and drives the rotating plate 2c to rotate. The lower clamping plate 2e is disposed on the rotating plate 2c. The clamping drive component 2f is disposed on the upper clamping plate 2d and drives the upper clamping plate 2d to move closer to or away from the lower clamping plate 2e.

[0053] The pressing and edge-trimming machine 22 is mounted on the frame 21 and located at the feeding end of the frame 21. The pressing and edge-trimming machine 22 is vertically connected to the frame 21. The pressing and edge-trimming machine 22 pushes the fabric into the space between the upper clamping plate 2d and the lower clamping plate 2e.

[0054] The material support 24 is mounted on the frame 21, the pressing machine 25 is mounted on the frame 21 and located above the material support 24, and the clamping plate 27 is mounted on the material support 24.

[0055] Specifically, in this embodiment, the fabric to be processed is square in shape, requiring folding of opposite sides and then folding in half. Initially, the first folding machine 23 and the second folding machine 26 are both located at the feeding end of the frame 21. The first folding machine 23 is located directly below the pressing and edge-trimming machine 22. The feeder 1 supplies a roll of fabric. The single layer of the roll enters the feeding end of the folding machine 2 along the conveying direction. First, the pressing and edge-trimming machine 22 moves downward to press the edge of the fabric to be folded between the upper clamping plate 2d and the lower clamping plate 2e. Then, the pressing and edge-trimming machine 22 trims the corners of the edge, making... The edges are gathered towards the central axis of the fabric, then the pressing and edge-trimming machine 22 moves upward, away from the fabric. The clamping drive 2f drives the upper clamping plate 2d to move towards the lower clamping plate 2e and completes the action of clamping the edge of the fabric. Then, the rotation drive 2b drives the rotating plate 2c to rotate at a preset angle to complete the folding action. Finally, the external drive drives the mounting plate 2a to move along the conveying direction of the frame 21, thereby transporting the fabric to the discharge end of the frame 21. Then, the second folding machine 26 moves to directly below the pressing and edge-trimming machine 22. The upper clamping plate 2d and the lower clamping plate 2e of the second folding machine 26... In a spaced-out state, the above actions are repeated. The pressing and edge-trimming machine 22 moves down to press the edge to be folded between the upper clamping plate 2d and the lower clamping plate 2e. Then, the pressing and edge-trimming machine 22 trims the corner of the edge, so that the corner is gathered towards the central axis of the fabric. Then, the pressing and edge-trimming machine 22 moves upward away from the fabric. The clamping drive 2f drives the upper clamping plate 2d to approach the lower clamping plate 2e and completes the action of clamping the edge of the fabric. Then, the rotation drive 2b drives the rotating plate 2c to rotate at a preset angle to complete the folding and edge-trimming action of the other side of the fabric. Then, the clamping plate 27 clamps... Holding the middle of the fabric, an external drive unit drives the second folding machine 26 to move along the conveying direction of the frame 21 and move to the discharge end of the frame 21. The second folding machine 26 overlaps with the first folding machine 23. Then, the transfer machine 3 transfers the folded fabric to the sewing machine 4. Finally, the sewing machine 4 completes the sewing process. The support component 24 is set on the frame 21 to give the fabric support force, so as to avoid the fabric sinking under the action of gravity and improve the production quality. The setting of the pressure machine 25 prevents the fabric from floating during the traction process, and also ensures the stability of the production quality.

[0056] By setting up a folding machine 2 consisting of a frame 21, a pressing and edge-trimming machine 22, a first folding machine 23, a material support 24, a pressing machine 25, a second folding machine 26, and a clamping plate 27, the edge-trimming, folding, and pulling of the fabric edge are realized, thereby improving production efficiency.

[0057] The pressing and edge-trimming machine 22 includes a hanging plate 221, a blade 222, and an edge-trimming component 223. The hanging plate 221 is located on the top of the frame 21. The blade 222 is scissor-connected to the hanging plate 221. The edge-trimming component 223 is slidably connected to the blade 222. There are two edge-trimming components 223, which are respectively located at both ends of the blade 222 along its length, and trim the two opposite corners of the edge.

[0058] The edge-rubbing component 223 includes a front drive component 2231, a front cutter 2232, a rear drive component 2233, and a rear cutter 2234. The front drive component 2231 is disposed on the blade plate 222 and drives the front cutter 2232 to move. The rear drive component 2233 is disposed on the blade plate 222 and drives the rear cutter 2234 to move. The front cutter 2232 and the rear cutter 2234 are arranged in parallel. The movement direction of the front cutter 2232 and the rear cutter 2234 is consistent with the length direction of the blade plate 222. The front cutter 2232 and the rear cutter 2234 are respectively located on both sides of the blade plate 222. Both the front cutter 2232 and the rear cutter 2234 are covered with... The main body has several gap strips at its bottom. During the movement of the front blade 2232 and the rear blade 2234, the scrap material enters the gaps under the pressure of the front blade 2232 and the blade plate 222, or the scrap material enters the gaps under the pressure of the rear blade 2234 and the blade plate 222, thus achieving the purpose of gathering the edges. The front drive component 2231 and the rear drive component 2233 are both cylinder-driven components. The front drive component 2231 drives the front blade 2232 to move relative to the blade plate 222, and the rear drive component 2233 drives the rear blade 2234 to move relative to the blade plate 222, thus completing the edge trimming of the fabric.

[0059] The second folding machine 26 also includes a lifting drive component 2m. The lifting drive component 2m is mounted on the mounting plate 2a and drives the rotating drive component 2b to move up and down. The lifting drive component 2m is a cylinder drive component, which causes the rotating drive component 2b, the rotating plate 2c, the upper clamping plate 2d, the lower clamping plate 2e and the clamping drive component 2f to move upward as a whole, beyond the upper surface of the clamping plate 27, so that the second folding machine 26 can smoothly clamp the edge of the fabric through the clamping plate 27 and reach the discharge end of the frame 21.

[0060] The material support component 24 includes a pallet 241 and a pallet drive component 242. The pallet drive component 242 is mounted on the frame 21 and drives the pallet 241 to move along the conveying direction. The pallet drive component 242 drives the pallet 241 to rise and fall, so that the height position of the pallet 241 meets the production requirements.

[0061] The clamping plate 27 includes a horizontal drive member 271, a vertical drive member 272, a movable plate 273, and a fixed plate 274. The horizontal drive member 271 is located on the support plate 241 and drives the vertical drive member 272 to move. The vertical drive member 272 drives the movable plate 273 to rise and fall. The fixed plate 274 is located on the support plate 241, and the fixed plate 274 is spaced apart from the support plate 241. Under the action of the horizontal drive member 271 and the vertical drive member 272, the movable plate 273 moves upward and backward to clamp the fabric and complete the folding of the fabric.

[0062] The pressing machine 25 includes a pressing plate 251, a pressing plate horizontal drive component 252, and a pressing plate lifting drive component 253. The pressing plate lifting drive component 253 is mounted on the frame 21 and drives the pressing plate horizontal drive component 252 to move up and down. The pressing plate horizontal drive component 252 drives the pressing plate 251 to move horizontally. The pressing plate 251 is L-shaped and is located directly above the support plate 241 with spacing. The pressing plate 251 and the support plate 241 cooperate to press the fabric and ensure that the fabric is smoothly conveyed in the horizontal direction.

[0063] The feeding machine 1 includes a cutting machine 11, which is mounted on the frame 21. The cutting machine 11 cuts the fabric. The folding machine 2 also includes a spraying machine 28, which is mounted on the frame 21 and located between the cutting machine 11 and the pressing and edge-trimming machine 22, so as to facilitate water spraying on the fabric to meet production needs.

[0064] The sewing machine also includes a spare part machine 5, which includes a first material feeder 51, a first material transfer machine 52, a second material feeder 53, a welding machine 54, and a finished product transfer part 55. The first material transfer machine 52 transfers the first material to the outlet of the second material feeder 53. The welding machine 54 welds the first material and the second material. The finished product transfer part 55 transfers the finished product to the support part 24. The first material feeder 51 supplies adhesive, and the second material feeder 53 supplies fabric. Preferably, a heating element is provided at the feeding end of the first material feeder 51 to heat the first material, ensuring that the first material is in a constant temperature state and ensuring the smoothness of the welding process of the welding machine 54 on the first material and the second material. The finished product transfer part 55 transfers the finished product after welding the first material and the second material to the support part 24. The finished product is bonded together with the fabric and enters the next process.

[0065] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
