Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to sewing head fabric preparation equipment. Background Technology

[0002] In the textile production process, after the fabric is woven, it is often only a short length. In order to facilitate the processing of the fabric, it needs to be sewn together to form a longer piece of fabric for subsequent processing. To improve the efficiency of sewing, sewing machines are often used.

[0003] During operation, the sewing machine needs to transport the rolled fabric to the machine frame, then loosen the fabric roll to find the fabric end, then flatten the fabric end, and then sew the flattened fabric end to the end of the previous fabric through the sewing mechanism of the sewing machine.

[0004] While existing technical solutions can achieve the sewing of fabric ends, the operation mostly relies entirely on manual labor, which is labor-intensive and time-consuming.

[0005] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0006] Therefore, it is necessary to provide a sewing head fabric preparation device to address the problems of high labor intensity, time and labor costs associated with manual operations.

[0007] A sewing fabric preparation device, comprising:

[0008] The main frame is equipped with a sewing head device and a fabric edge fixing device. The fabric edge fixing device is used to fix the beginning and end of two adjacent fabric pieces, and the sewing head device is used to sew the fixed beginning and end of the fabric pieces together.

[0009] The material discharge device is mounted on the main frame and is used to allow the sewn fabric end to leave the sewing device.

[0010] A roll-up device is provided on the main frame and is used to unroll the fabric so that the beginning or end of the fabric can be fixed on the selvage fixing device.

[0011] A feeding device, which is mounted on the main frame, is used to feed the rolled fabric to the unwinding device;

[0012] A buffer device, which is mounted on the main frame, is used to store multiple rolls of fabric simultaneously;

[0013] A lifting device, which is mounted on the main frame, is used to transport one roll of fabric from the buffer device to the unloading device.

[0014] The aforementioned fabric preparation equipment uses a buffer device to simultaneously store multiple rolls of fabric, allowing the equipment to sew multiple rolls of fabric sequentially. A lifting device conveys one roll of fabric from the buffer device to a feeding device, which then sends the roll to a loosening device. The loosening device unrolls the fabric, making it easier for workers to locate the beginning of the fabric and secure it, along with the end of another fabric, to a sewing device. The sewing device automatically sews the secured beginning and end of the fabric together. The sewn beginning and end of the fabric can then be output to a designated location via a discharge device. The entire operation requires no manual assistance except for the buffer device and the sewing device, resulting in a high degree of automation, minimal manual labor, and saving time and labor.

[0015] In one embodiment, the feeding device and the unwinding device are arranged vertically, and the discharge device and the feeding device are arranged vertically.

[0016] In the above embodiments, the vertical distribution makes the overall structure of the device more compact and saves floor space.

[0017] In one embodiment, the buffer device includes a first driver, a buffer frame, a first stop, and a second driver. The buffer frame is rotatably connected to the main frame via the first driver. The first stop is slidably disposed between the buffer frame and the lifting device. The second driver is drively connected to the first stop to drive the first stop to move longitudinally relative to the buffer frame.

[0018] In the above embodiment, by rotating the buffer rack to connect it to the main frame, the buffer rack can be tilted relative to the lifting device. At the same time, the tilt angle of the buffer rack can be adjusted by the first driver, so that the rolls of fabric on the buffer rack can automatically slide down to the lifting device. Meanwhile, the first stop can block the rolls of fabric on the buffer rack, so that only one roll of fabric can slide down to the lifting device at a time.

[0019] In one embodiment, the lifting device includes a trough, a first guide rail, a second guide rail, and a third driver. A first sliding member and a second sliding member are slidably disposed on the first guide rail and the second guide rail, respectively. The first sliding member and the second sliding member are rotatably connected to a first part and a second part of the trough, respectively. The third driver is drivenly connected to the trough to drive the trough to move longitudinally along the first guide rail. The second part is located above the first part. The top of the second guide rail has a bent portion, and the bent portion is located above the feeding device.

[0020] In the above embodiment, the third driver can make the material trough move longitudinally along the direction of the first guide rail, so that the material trough can drive the rolled fabric inside it to move upward. At the same time, the first and second sliding members can be rotatably connected to the material trough, so that when the material trough moves to the bending part, its second part can move along the bending part, thereby causing the material trough to flip over and pour the rolled fabric inside the material trough onto the feeding device.

[0021] In one embodiment, the feeding device includes a slide, a second stop, a fourth driver, a bracket, a fifth driver, and a pusher. The bracket is mounted on the main frame and is used to receive rolled fabric. The pusher is slidably mounted on the bracket. The fifth driver is connected to the pusher to drive the pusher to move laterally relative to the bracket. The fourth driver is mounted on the bracket and is drivenly connected to the second stop to drive the second stop to move longitudinally relative to the bracket. The first end and the second end of the slide are respectively close to the lifting device and the second stop, and the first end and the second end of the slide are vertically distributed.

[0022] In the above embodiment, the roll of fabric output from the lifting device is received by the slide table, and the roll of fabric on the slide table is blocked by the second stop to control the time when the roll of fabric slides onto the support. The roll of fabric that falls onto the support can be pushed onto the unwinding device by the pusher for unwinding operation.

[0023] In one embodiment, the unwinding device includes an unwinding frame, a roller assembly, and a sixth driver. The top of the unwinding frame has a receiving structure. The roller assembly is disposed between the selvage fixing device and the unwinding frame. The sixth driver is throttle-connected to the roller assembly to drive the roller assembly to rotate.

[0024] In the above embodiment, the roll of fabric delivered from the unloading device can be caught by the unloading frame, and the stability of the roll of fabric on the unloading frame is enhanced by the catching structure. At the same time, the roller group is driven to rotate by the sixth driver, so that the roller group can drive the roll of fabric on the unloading frame to rotate, so that the roll of fabric is unloaded and the fabric end can be conveyed to the selvage fixing device.

[0025] In one embodiment, the selvage fixing device includes a fixing frame, a seventh driver, and a pressure member. A first side of the fixing frame is located below the unwinding device, and a second side of the fixing frame is located below the pressure member. The seventh driver is drively connected to the pressure member to drive the pressure member to move longitudinally relative to the fixing frame.

[0026] In the above embodiment, the fabric end loosened by the unwinding device is collected by the fixing frame, and the fabric end and the tail of the previous fabric are pressed and fixed by the seventh driver, so that the fabric end and the tail can be sewn together by the sewing device.

[0027] In one embodiment, the fixing frame includes a first frame, a second frame, and an eighth actuator. The first frame has a fixing pin on its side away from the unwinding device. The eighth actuator is kinetically connected to the second frame to drive the second frame to move axially along the fixing pin.

[0028] In the above embodiment, by placing the fabric on the second frame and passing the fixing pin through the fabric, the fixing effect of the fabric on the fabric edge fixing device can be enhanced. At the same time, the second frame is driven to move along the axis of the fixing pin by the eighth driver, so that the second frame can automatically move the fabric off the fixing pin, reducing the workload of the workers.

[0029] In one embodiment, the sewing head device includes a third guide rail, a sewing head machine, a ninth driver, a fan, and an air duct. The sewing head machine is slidably mounted on the third guide rail. The ninth driver is drivenly connected to the sewing head machine to drive the sewing head machine to move on the third guide rail. The first end of the air duct is mounted on the sewing head machine, and the second end of the air duct is connected to the air inlet of the fan.

[0030] In the above embodiment, the sewing machine is driven by the ninth driver to move on the third guide rail, so that the moving sewing machine can perform sewing operations on the fabric. At the same time, the air at the sewing machine can be extracted by the fan, so that the flowing air can flatten the fabric ends.

[0031] In one embodiment, the discharge device includes a tenth driver, a first roller, a second roller, a connector, and a hopper. The tenth driver is tractively connected to the first roller and the second roller to simultaneously drive the first roller and the second roller to rotate. The hopper is tractively connected to the second roller via the connector so that the second roller can drive the hopper to rotate.

[0032] In the above embodiment, the first roller and the second roller are driven to rotate by the tenth driver, so that the first roller and the second roller can transfer the sewn fabric to the fabric hopper. At the same time, the second roller can drive the fabric hopper to rotate during the rotation, so that the fabric hopper can pour out the fabric accumulated inside it. Attached Figure Description

[0078] See Figures 1-2 An embodiment of the present invention provides a fabric preparation device for sewing ends, comprising a main frame 1, a feeding device 2, a loosening device 3, a feeding device 4, a buffer device 5, and a lifting device 6. The main frame 1 provides installation positions for the feeding device 2, the loosening device 3, the feeding device 4, the buffer device 5, and the lifting device 6, thereby centrally integrating these components.

[0079] The main frame 1 is equipped with a sewing head device 7 and a selvage fixing device 8. The selvage fixing device 8 is used to fix the beginning and end of two adjacent fabric pieces, and the sewing head device 7 is used to sew the fixed beginning and end of the fabric pieces together. Specifically, the main frame 1 includes a top frame 11, a middle frame 12, and a side frame 13. The middle frame 12 and the side frame 13 are respectively located in the middle and side of the bottom surface of the top frame 11. Both the sewing head device 7 and the selvage fixing device 8 are located in the middle of the main frame 1. That is, both the sewing head device 7 and the selvage fixing device 8 are located inside the middle frame 12. The sewing mechanism of the sewing head device 7 is located inside the selvage fixing device 8, so that the sewing head device 7 can sew the fabric beginning fixed inside the selvage fixing device 8 through its sewing mechanism.

[0080] The feeding device 2 is installed on the main frame 1 and is used to allow the sewn fabric end to leave the sewing head device 7. Specifically, the feeding device 2 is installed inside the top frame 11, above the sewing head device 7 and the sewing edge fixing device 8, so that the sewn fabric can be output from the upper side of the sewing head device 7 and the sewing edge fixing device 8. This allows the fabric end to hang down onto the sewing edge fixing device 8 when the fabric is output to the fabric tail, so that the sewing edge fixing device 8 can fix the fabric tail and the fabric end of the next piece of fabric.

[0081] The unwinding device 3 is mounted on the main frame 1 and is used to unwind the rolled fabric so that the fabric end or tail can be fixed to the selvage fixing device 8. Specifically, the unwinding device 3 is located inside the middle frame 12, and the selvage fixing device 8 is located between the sewing end device 7 and the unwinding device 3. This allows the fabric end unwinding by the unwinding device 3 to be fed to the selvage fixing device 8 and then fixed by the selvage fixing device 8.

[0082] The feeding device 4 is mounted on the main frame 1 and is used to feed the rolled fabric to the unwinding device 3. Specifically, one side of the feeding device 4 is located inside the middle frame 12, and the other side of the feeding device 4 is close to the side frame 13. The feeding device 4 is located above the selvage fixing device 8, the sewing head device 7, and the unwinding device 3, so that the rolled fabric on the feeding device 4 can fall onto the unwinding device 3 by gravity.

[0083] The buffer device 5 is installed on the main frame 1 and is used to store multiple rolls of fabric simultaneously. Specifically, the buffer device 5 is placed on the ground and located to the side of the main frame 1, so that workers can place the rolls of fabric onto it for storage.

[0084] The lifting device 6 is mounted on the main frame 1 and is used to transport one roll of fabric from the buffer device 5 to the unloading device 4. Specifically, the lifting device 6 is located within the side frame 13, between the buffer device 5 and the unloading device 4. The buffer device 5 and the unloading device 4 are located near the bottom and top of the lifting device 6, respectively. The lifting device 6 can transport the roll of fabric located at the bottom to the unloading device 4 located at the top.

[0085] The aforementioned fabric preparation equipment for sewing ends uses a buffer device 5 to simultaneously store multiple rolls of fabric, allowing the equipment to sew multiple rolls of fabric sequentially. A lifting device 6 conveys one roll of fabric from the buffer device 5 to a feeding device 4, which then feeds the roll to a loosening device 3. The loosening device 3 loosens the roll of fabric, making it easier for workers to find the beginning of the fabric and fix it, along with the end of another fabric, to a fabric edge fixing device 8. The sewing end device 7 automatically sews the fixed beginning and end of the fabric together. The sewn beginning and end of the fabric can then be output to a designated location via a discharge device 2. The entire operation requires no manual assistance except for the buffer device 5 and the sewing end device 7, resulting in a high degree of automation, minimal manual labor, and saving time and labor.

[0086] In one embodiment, the feeding device 4 and the unwinding device 3 are arranged vertically, as are the discharge device 2 and the feeding device 4. Specifically, the feeding device 4 is located between the discharge device 2 and the unwinding device 3. This vertical arrangement makes the overall structure of the equipment more compact and saves floor space.

[0087] See Figures 1-3 In one embodiment, the buffer device 5 includes a first driver 51, a buffer frame 52, a first stop 53, and a second driver 54. The buffer frame 52 is rotatably connected to the main frame 1 via the first driver 51. The first stop 53 is slidably disposed between the buffer frame 52 and the lifting device 6. The second driver 54 is drively connected to the first stop 53 to drive the first stop 53 to move longitudinally relative to the buffer frame 52.

[0088] In a specific configuration, the first driver 51 includes a cylinder base 511 and a first cylinder 512. The bottom of the first cylinder 512 is rotatably connected to the cylinder base 511, and the top of the first cylinder 512 is rotatably connected to the first end of the buffer frame 52. The opposite second end of the buffer frame 52 is rotatably connected to a support. The support can be placed on a bottom surface or connected to the main frame 1. Specifically, in this embodiment, the cylinder shaft of the first cylinder 512 is rotatably connected to the first end of the buffer frame 52. This allows the buffer frame 52 to rotate relative to the main frame 1 when the first cylinder 512 drives its cylinder shaft to extend and retract. This allows adjustment of the angle between the buffer frame 52, the main frame 1, and the ground, enabling the buffer frame 52 to better deliver the rolled fabric to the lifting device 6.

[0089] Furthermore, the second actuator 54 is a second cylinder, which is mounted on the main frame 1, and its cylinder shaft is connected to the top of the first stop 53. This allows the first stop 53 to move longitudinally between the buffer frame 52 and the lifting device 6 when the first cylinder 512 drives its cylinder shaft to extend and retract. When the distance between the bottom of the first stop 53 and the second end of the buffer frame 52 is greater than the diameter of the rolled fabric, the first stop 53 no longer intercepts the rolled fabric, and the rolled fabric on the buffer frame 52 can roll into the lifting device 6 under gravity.

[0090] In the above embodiment, by rotating the buffer rack 52 to the main frame 1, the buffer rack 52 can be tilted relative to the lifting device 6. At the same time, the tilt angle of the buffer rack 52 can be adjusted by the first driver 51, so that the roll of fabric on the buffer rack 52 can automatically slide down to the lifting device 6. Meanwhile, the first stop 53 can block the roll of fabric on the buffer rack 52, so that only one roll of fabric can slide down to the lifting device 6 at a time.

[0091] In one embodiment, the lifting device 6 includes a trough 61, a first guide rail 62, a second guide rail 63, and a third driver 64. A first sliding member 65 and a second sliding member 66 are slidably provided on the first guide rail 62 and the second guide rail 63, respectively. The first sliding member 65 and the second sliding member 66 are rotatably connected to a first part and a second part of the trough 61, respectively. The third driver 64 is drivenly connected to the trough 61 to drive the trough 61 to move longitudinally along the first guide rail 62. The second part is located above the first part. The top of the second guide rail 63 has a bent portion 67 located above the feeding device 4.

[0092] In its specific configuration, the third drive 64 includes a first motor 641, a first chain 642, and two first sprockets 643. The first motor 641 is mounted on the side frame 13. The first guide rail 62 and the second guide rail 63 are both mounted inside the side frame 13. The two first sprockets 643 are located on the upper and lower sides of the first guide rail 62, respectively. One of the first sprockets 643 is connected to the motor shaft of the first motor 641, and the other sprocket is rotatably connected to the side frame 13. The first chain 642 is sleeved on and meshes with the two first sprockets 643. A first sliding member 65 is mounted on the first chain 642. When the first motor 641 drives its motor shaft to rotate the first sprockets 643, the first chain 642 can move accordingly, allowing the first sliding member 65 to move longitudinally on the first guide rail 62, thereby driving the trough 61 to move longitudinally within the side frame 13.

[0093] The second guide rail 63 is parallel to the first guide rail 62. The bottom of the bent portion 67 is close to the first guide rail 62, and the top of the bent portion is close to the feeding device 4 and located on the upper side of the feeding device 4. When the first sliding member 65 moves longitudinally on the first guide rail 62, the second sliding member 66 also moves longitudinally on the second guide rail 63. When the second sliding member 66 moves to the bent portion 67, the second sliding member 66 moves along the bent portion 67 towards the feeding device 4, while the first sliding member 65 continues to move upward along the first guide rail 62. At this time, since the first sliding member 65 and the second sliding member 66 are rotatably connected to the first and second parts of the material trough 61 respectively, and the second part is located on the upper side of the first part, when the second sliding member 66 moves along the bent portion towards the feeding device 4, the upper side of the material trough 61 can be flipped towards the feeding device 4, thereby allowing the rolled fabric in the material trough 61 to be poured onto the feeding device 4.

[0094] It is worth mentioning that the distance D1 between the top center of the bent portion 67 and the top center of the first guide rail 62 can be equal to the distance D2 between the second portion and the first portion. See details in [reference needed]. Figure 3The first and second portions of the feed trough 61 are located at the middle of the first sliding member 65 and the second sliding member 66, respectively. Therefore, the distance D2 between the second portion and the first portion is the distance between the center of the first sliding member 65 and the center of the second sliding member 66. That is, the distance from the top center of the bent portion 67 to the top center of the first guide rail 62 can be equal to the distance between the first sliding member 65 and the second sliding member 66. When the first sliding member 65 moves upward along the first guide rail 62, the second sliding member 66 can move upward along the second guide rail 63 to its bent portion 67. Therefore, by making the distance D1 between the top of the bent portion 67 and the top of the first guide rail 62 equal to the distance D2 between the second portion and the first portion, when the first slider 65 slides to the top of the first guide rail 62, the second slider 66 can slide to the top of the bent portion 67, thereby preventing the second slider 66 from moving out of the bent portion 67 when the first slider 65 moves along the first guide rail 62; and preventing the first slider 65 from moving out of the first guide rail 62 when the second slider 66 moves along the bent portion 67.

[0095] More specifically, there are two first guide rails 62 and two second guide rails 63. The two first guide rails 62 are symmetrically arranged on the two opposing inner sidewalls of the side frame 13, and the two second guide rails 63 are symmetrically arranged on the two opposing inner sidewalls of the side frame 13. The second guide rails 63 are located between the first guide rails 62 and the feeding device 4. The first parts on the two sides of the material trough 61 are rotatably connected to the first sliding members 65 on the two first guide rails 62, and the second parts on the two sides of the material trough 61 are rotatably connected to the second sliding members 66 on the two second guide rails 63. This further enhances the stability of the material trough 61 during movement.

[0096] In the above embodiment, the third driver 64 can cause the material trough 61 to move longitudinally along the direction of the first guide rail 62, so that the material trough 61 can drive the rolled fabric inside it to move upward. At the same time, the first sliding member 65 and the second sliding member 66 can be rotatably connected to the material trough 61, so that when the material trough 61 moves to the bending part 67, its second part can move along the bending part 67, and the first part continues to move along the first guide rail 62, so that the material trough 61 can be flipped, and then the rolled fabric inside the material trough 61 can be poured onto the feeding device 4.

[0097] See Figure 1 , Figure 2 and Figure 4In one embodiment, the feeding device 4 includes a slide table 41, a second stop 42, a fourth driver 43, a bracket 44, a fifth driver 45, and a pusher 46. The bracket 44 is mounted on the main frame 1 and is used to receive rolled fabric. The pusher 46 is slidably mounted on the bracket 44. The fifth driver 45 is connected to the pusher 46 to drive the pusher 46 to move laterally relative to the bracket 44. The fourth driver 43 is mounted on the bracket 44 and is drivenly connected to the second stop 42 to drive the second stop 42 to move longitudinally relative to the bracket 44. The first end and the second end of the slide table 41 are close to the lifting device 6 and the second stop 42, respectively, and the first end and the second end of the slide table 41 are distributed vertically.

[0098] In the specific configuration, the slide 41 is inclined between the middle frame 12 and the side frame 13, with the first end of the slide 41 located below the bent portion 67. The fourth actuator 43 uses a standard cylinder, and the second stop 42 is located at the top of the cylinder shaft of the fourth actuator 43. When the fourth actuator 43 drives its cylinder shaft to move the second stop 42 to the lowest position, the top of the second stop 42 is lower than the second end of the slide 41. When the fourth actuator 43 drives its cylinder shaft to move the second stop 42 to the highest position, the top of the second stop 42 is higher than the second end of the slide 41. This allows the fourth actuator 43 to drive the second stop 42 to block the rolled fabric that has rolled onto the second end of the slide 41.

[0099] In addition, a bending frame 47 is provided on the side of the support 44 away from the slide table 41, and the bottom of the bending frame 47 is connected to the support 44. The bending frame 47 intercepts the rolled fabric on the support 44, preventing the rolled fabric from rolling directly onto the unwinding device 3. A third guide rail 71 is provided on the support 44 and the bending frame 47. A third sliding member 48 and a fourth sliding member 49 are slidably provided on the third guide rail 71. A fifth driver 45 is rotatably connected to the third sliding member 48, and a pusher 46 is rotatably connected to the fourth sliding member 49. The fifth driver 45 is also a standard cylinder. The bottom of the cylinder of the fifth driver 45 is rotatably connected to the third sliding member 48, and the cylinder shaft of the fifth driver 45 is connected to the pusher 46. When the fifth driver 45 drives its cylinder shaft to move the pusher 46, the pusher 46 can push the rolled fabric out of the bending frame 47, so that the rolled fabric can fall into the unwinding device 3.

[0100] In the above embodiment, the roll of fabric output from the lifting device 6 is received by the slide table 41, and the roll of fabric on the slide table 41 is blocked by the second stop 42 to control the time when the roll of fabric slides onto the support 44. The roll of fabric that falls onto the support 44 can be pushed onto the unwinding device 3 by the pusher 46 for unwinding operation.

[0101] In one embodiment, the unwinding device 3 includes an unwinding frame 31, a roller assembly 32, and a sixth driver 33. The top of the unwinding frame 31 has a receiving structure. The roller assembly 32 is disposed between the selvage fixing device 8 and the unwinding frame 31. The sixth driver 33 is connected to the roller assembly 32 in a transmission connection to drive the roller assembly 32 to rotate.

[0102] In its specific configuration, the unwinding frame 31 includes two first shafts 311 and two second shafts 312. Both the first shafts 311 and the second shafts 312 are rotatably mounted on the central frame 12. The diameter of each first shaft 311 is larger than the diameter of each second shaft 312, and each first shaft 311 is located between the two second shafts 312. The top of the unwinding frame 31 has an arc-shaped receiving structure. That is, the line connecting the axes of the two first shafts 311 and the two second shafts 312 is an arc. This allows the tops of the two first shafts 311 and the two second shafts 312 to form an arc-shaped receiving structure, which better fits the rolled fabric, thereby enhancing the stability of the rolled fabric on the unwinding frame 31. Additionally, the bending frame 47 has an opening, and the arc-shaped receiving structure of the unwinding frame 31 is located below the opening. That is, the orthographic projection of the bending frame 47 on the ground coincides with the orthographic projection of the unwinding frame 31 on the ground. This allows the rolled fabric on the bending frame 47 to fall vertically onto the unwinding frame 31, ensuring structural compactness.

[0103] Furthermore, the roller assembly 32 is located below the bracket 44. The sixth drive 33 is a rotary motor, which is connected to the roller assembly 32 via a sprocket and chain structure. In the illustration of this embodiment, the rotary motor drives the roller assembly 32 to rotate counterclockwise so that the fabric end on the unwinding frame 31 can be conveyed to the selvage fixing device 8.

[0104] In the above embodiment, the roll of fabric delivered from the unloading device 4 can be received by the unwinding frame 31, and the stability of the roll of fabric on the unwinding frame 31 is enhanced by the arc-shaped receiving structure. At the same time, the roller assembly 32 is driven to rotate by the sixth driver 33, so that the roller assembly 32 can drive the roll of fabric on the unwinding frame 31 to rotate, so that the roll of fabric is unwound and the fabric end can be conveyed to the fabric edge fixing device 8.

[0105] See Figure 1 , Figure 4 , Figure 5 and Figure 6 In one embodiment, the selvage fixing device 8 includes a fixing frame 81, a seventh driver 82, and a pressing member 83. The first side of the fixing frame 81 is located below the unwinding device 3, and the opposite second side of the fixing frame 81 is located below the pressing member 83. The seventh driver 82 is drivenly connected to the pressing member 83 to drive the pressing member 83 to move longitudinally relative to the fixing frame 81.

[0106] In the specific configuration, both the fixing frame 81 and the seventh actuator 82 are mounted on the central frame 12. The seventh actuator 82 uses a standard cylinder, and the pressing component 83 is located at the bottom of the cylinder shaft of the seventh actuator 82. The seventh actuator 82 can drive the pressing component 83 to move downwards, pressing and fixing the fabric on the fixing frame 81.

[0107] In the above embodiment, the fabric end loosened by the unwinding device 3 is collected by the fixing frame 81, and the pressing member 83 can be driven by the seventh driver 82 to press and fix the fabric end and the tail of the previous fabric, so that the fabric end and the tail can be sewn together by the sewing device 7.

[0108] In one embodiment, the fixing frame 81 includes a first frame 811, a second frame 812 and an eighth driver 813. The first frame 811 is provided with a fixing pin 814 on the side away from the unwinding device 3. The eighth driver 813 is connected to the second frame 812 in a transmission connection to drive the second frame 812 to move along the axial direction of the fixing pin 814.

[0109] In the specific configuration, a first groove 815 is provided on the first side of the first frame 811, and a fixing pin 814 is disposed inside the first groove 815, with the fixing pin 814 parallel to the first side. By placing the fixing pin 814 inside the first groove 815, the risk of workers accidentally touching the fixing pin 814 is reduced. The bottom surface of the second frame 812 contacts the top surface of the first frame 811, and a second groove 816 is provided on the first side of the second frame 812 away from the unwinding device 3, and the second groove 816 communicates with the first groove 815. This allows the end of the fabric to enter the first groove 815 through the second groove 816 and be fixed with the fixing pin 814. The eighth actuator 813 is a standard cylinder, and the cylinder shaft of the eighth actuator 813 is connected to the second frame 812. The eighth actuator 813 can drive the second frame 812 to move relative to the first frame 811 to form a fixing channel defined by the overlapping area of ​​the second groove 816 and the first groove 815. When the fixing pin 814 is located in the fixing channel, the fabric can be fixed by the fixing pin 814. When the eighth driver 813 drives the second frame 812 to cover the fixing pin 814, so that the fixing pin 814 is no longer located in the fixing channel, the fabric can no longer be fixed by the fixing pin 814.

[0110] In the above embodiment, by placing the fabric on the second frame 812 and passing the fixing pin 814 through the fabric, the fixing effect of the fabric on the fabric edge fixing device 8 can be enhanced. At the same time, the second frame 812 is driven to move along the axial direction of the fixing pin 814 by the eighth driver 813, so that the second frame 812 can automatically move the fabric off the fixing pin 814, reducing the workload of the workers.

[0111] In one embodiment, the sewing head device 7 includes a third guide rail 71, a sewing head machine 72, a ninth driver 73, a fan 74, and an air duct 75. The sewing head machine 72 is slidably mounted on the third guide rail 71. The ninth driver 73 is drivenly connected to the sewing head machine 72 to drive the sewing head machine 72 to move on the third guide rail 71. The first end of the air duct 75 is mounted on the sewing head machine 72, and the second end of the air duct 75 is connected to the air inlet of the fan 74.

[0112] In the specific configuration, the third guide rail 71 is parallel to the first side of the first frame 811. The ninth drive unit 73 includes a second motor 731, a synchronous belt 732, pulleys 733, and a mounting base 734. Wheel frames are provided on both sides of the third guide rail 71. The pulleys 733 are rotatably mounted on the wheel frames. The second motor 731 is rotatably connected to the pulleys 733. The synchronous belt 732 is fitted onto the two pulleys 733. The mounting base 734 is fixed to the synchronous belt 732, and the sewing machine 72 is fixed to the mounting base 734. When the second motor 731 drives the pulleys 733 to rotate, the synchronous belt 732 rotates accordingly, thereby driving the sewing machine 72 on the mounting base 734 to move along the third guide rail 71. A guide wheel 76 is rotatably provided on the mounting base 734, and the guide wheel 76 is slidably connected to the third guide rail 71, enhancing the stability of the mounting base 734 when moving along the third guide rail 71.

[0113] In addition, a filter box 77 is connected to the air duct 75. The filter box 77 can filter impurities and fabric strips in the air drawn out through the air duct 75, thus protecting the fan 74.

[0114] In the above embodiment, the sewing machine 72 is driven by the ninth driver 73 to move on the third guide rail 71, so that the moving sewing machine 72 can perform sewing operations on the fabric. At the same time, the fan 74 can extract the air from the sewing machine 72, so that the flowing air can flatten the fabric ends.

[0115] See Figure 1 , Figure 2 and Figure 7 In one embodiment, the discharge device 2 includes a tenth driver 21, a first roller 22, a second roller 23, a connector 24, and a hopper 25. The tenth driver 21 is driven to drive the first roller 22 and the second roller 23 to rotate simultaneously. The hopper 25 is driven to drive the second roller 23 through the connector 24 so that the second roller 23 can drive the hopper 25 to rotate.

[0116] In its specific configuration, the tenth actuator 21 is a rotary motor, mounted on the top frame 11, and connected to the first roller 22 and the second roller 23 via a sprocket and chain structure. Specifically, the motor shafts of the first roller 22, the second roller 23, and the tenth actuator 21 are all equipped with second sprockets 26, and these second sprockets are all connected via the same second chain. When the tenth actuator 21 drives its motor shaft to rotate, the first roller 22 and the second roller 23 rotate synchronously. The tenth actuator 21 is located between the first roller 22 and the second roller 23, with the first roller 22 positioned above the bracket 44. This allows the sewn fabric to be sequentially transferred to the fabric tray 25 via the first roller 22 and the second roller 23.

[0117] Furthermore, the connecting member 24 includes a connecting rod 241, a third sprocket 242, and a third chain 243. The third sprocket 242 is rotatably mounted on the top frame 11, and the third chain 243 is sleeved on the third sprocket 242 and the second sprocket 26 of the second roller 23. This allows the second roller 23 to drive the third sprocket 242 to rotate synchronously during rotation. The top of the swivel bucket 25 is rotatably mounted on the top frame 11. The first and second ends of the connecting rod 241 are rotatably connected to the third sprocket 242 and the middle of the swivel bucket 25, respectively, and the diameter of the third sprocket 242 is larger than the diameter of the second sprocket 26. When the second roller 23 drives the third sprocket 242 to rotate, the first end of the connecting rod 241 rotates on the third sprocket 242, thereby driving the second end of the connecting rod 241 to pull the swivel bucket 25, allowing the swivel bucket 25 to rotate relative to the top frame 11.

[0118] In the above embodiment, the first roller 22 and the second roller 23 are driven to rotate by the tenth driver 21, so that the first roller 22 and the second roller 23 can transfer the sewn fabric to the fabric hopper 25. At the same time, the second roller 23 can drive the fabric hopper 25 to rotate during the rotation, so that the fabric hopper 25 can pour out the fabric accumulated inside it.

[0119] by Figures 1-7Using the example position, in actual operation, the operator can place multiple rolls of fabric sequentially on the buffer rack 52. Simultaneously, the angle between the buffer rack 52 and the ground is adjusted by the first cylinder 512, allowing the rolls of fabric on the buffer rack 52 to roll more effectively to the first stop 53. When it is necessary to transfer rolls of fabric to the feeding device 4, the second driver 54 drives the first stop 53 upwards, allowing the rolls of fabric blocked by the first stop 53 to enter the material trough 61. After one roll of fabric enters the material trough 61, the second driver 54 immediately drives the first stop 53 downwards to continue blocking the next roll of fabric on the buffer rack 52. Simultaneously, the third driver 64 allows the material trough 61 to move longitudinally along the direction of the first guide rail 62. When the material trough 61 reaches the bending part 67, it can rotate clockwise, pouring the rolls of fabric onto the slide table 41. Due to the tilted state of the slide table 41, the rolled fabric will roll down onto the second stop 42. When it is necessary to transfer the rolled fabric to the support 44, the fourth driver 43 drives the second stop 42 downward, allowing the rolled fabric blocked by the second stop 42 to roll onto the support 44. After one roll of fabric rolls onto the support 44, the fourth driver 43 immediately drives the second stop 42 upward to continue blocking the next roll of fabric on the slide table 41. The rolled fabric on the support 44 can be blocked by the bending frame 47 to prevent it from rolling directly onto the unwinding frame 31. When it is necessary to transfer the rolled fabric to the unwinding device 3, the fifth driver 45 drives the pusher 46 to move to the right, causing the pusher 46 to push the rolled fabric off the bending frame 47, allowing the rolled fabric to fall onto the unwinding frame 31. The rolled fabric that falls onto the unwinding frame 31 can contact the roller assembly 32, so that when the sixth drive 33 drives the two rollers on the roller assembly 32 to rotate counterclockwise simultaneously, the rolled fabric on the unwinding frame 31 will rotate clockwise until the end of the rolled fabric contacts the roller assembly 32. The end of the fabric can then move to the left as the roller assembly 32 rotates until it falls into the fabric edge fixing device 8. At this point, the worker can stretch the fabric end onto the fixing frame 81 and secure it by passing it through the fixing needle 814. The worker can then stretch the end of the fabric from the discharge device onto the fixing frame 81 and secure it by passing it through the fixing needle 814. After securing, the seventh drive 82 moves the pressure member 83 downwards to press and secure the fabric end and end. Then, the ninth drive 73 drives the sewing machine 72 to move along the third guide rail 71 to sew the pressed fabric end and end. After sewing is completed, the eighth actuator drives the second frame 812 to move, so that the fabric head and tail are automatically removed from the fixed needle 814. Then, the tenth actuator 21 synchronously drives the first roller 22 and the second roller 23 to rotate clockwise, so that the sewn fabric head and tail move upward to the first roller 22 and then move into the fabric hopper via the second roller 23.When the fabric is passed to the point where its tail comes into contact with the first roller 22, the tenth drive 21 stops driving so that the tail can be pulled onto the fixing frame 81 by the worker for sewing with the end of the next piece of fabric.
