Description

Technical Field

[0001] The invention belongs to the technical field of sewing machine tools, and in particular relates to a cutting and sewing integrated machine for curtain processing. Background Art

[0002] Curtains are a kind of fabric used to decorate and cover windows. They have the dual functions of being practical and beautiful. Curtains are very common decorative materials in daily life. The production and processing technology of curtains is relatively simple, mainly including the following steps: Design: Choose the appropriate fabric, color and style according to customer needs and space style; Measurement: Accurately measure the window size to ensure the appropriate size of the curtain; Cutting: Cut the fabric according to the design drawings, and pay attention to leaving seams; Sewing: Sew the cut fabric to make it into the shape of the curtain. In the subsequent actual installation process, it is also necessary to install accessories such as slide rails and drawstrings, and finally hang the curtain on the window and adjust it to the appropriate position.

[0003] Although the processing technology of curtains is relatively simple, the processing of curtains currently generally relies on manual operation. When large quantities of curtains need to be processed, a large amount of manpower is required, which not only increases labor costs, but also is very time-consuming and labor-intensive. In the actual production and processing process, large-scale batch processing will increase the fatigue intensity of production personnel. In addition, curtains with different size requirements generally require manual precise measurement and then cutting. After cutting, they are sewn using sewing equipment. The operation process is relatively time-consuming and labor-intensive, and will also affect the production and processing progress to a certain extent. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a cutting and sewing machine for curtain processing.

[0005] The technical solution adopted to solve the above technical problems is: a cutting and sewing machine for curtain processing, comprising a feeding mechanism for releasing curtain fabric, and an automatic sewing mechanism is provided on one side of the feeding mechanism;

[0006] A supporting mechanism is provided on the other side of the automatic sewing mechanism, and a clamping and conveying mechanism for clamping and conveying curtain fabrics is installed on the top of the supporting mechanism;

[0007] An adsorption and fixing mechanism is provided in the middle of the support mechanism, and a longitudinal cutting mechanism is installed at the rear end of the adsorption and fixing mechanism for longitudinally cutting the curtain fabric;

[0008] A transverse cutting mechanism is fixedly installed on a side of the support mechanism away from the automatic sewing mechanism, an anti-outward turning mechanism is installed on one side of the transverse cutting mechanism, and a cloth tape sewing assembly is also installed on a side of the front end of the support mechanism away from the automatic sewing mechanism.

[0009] Furthermore, the material discharge mechanism includes a material discharge seat, on which a cloth roller for winding curtain fabric is placed, a material discharge reducer for driving the cloth roller to rotate is installed at the rear end of the material discharge seat, and one side between the front and rear ends of the inner wall of the material discharge seat is also rotatably connected to two limit rollers for limiting the curtain fabric.

[0010] Through the above technical scheme, the unloading mechanism is used for the uniform unloading of curtain fabrics to ensure that the release speed of the curtain fabrics can be adapted to the subsequent cutting and sewing. During the actual processing, the unloading reducer drives the fabric roller to rotate, and the end of the curtain fabric will pass between the two limiting rollers to ensure stability during the unloading process. At the same time, it can also prevent the soft curtain fabrics from folding or twisting. The end of the curtain fabric will be directed to move under the traction of the clamping and conveying mechanism to ensure stability during the entire processing process.

[0011] Furthermore, the automatic sewing mechanism includes a sewing machine, which is provided with two sets of conveyor belts for conveying curtain fabrics. A transmission assembly for driving the conveyor belts is installed at the rear end of the sewing machine, a sewing machine body is installed on one side of the rear end of the sewing machine, and limit switches are installed on both sides of the rear end of the top of the sewing machine.

[0012] Through the above technical scheme, the automatic sewing mechanism is mainly used for side sewing of curtain fabrics. After the curtain fabrics are laid flat on the sewing machine bed, the transmission assembly drives the conveyor belt to move in a directional manner. During this process, the conveyor belt will cooperate with the sewing speed of the sewing machine body to drive the curtain fabric to move precisely to ensure stability during the sewing process.

[0013] Furthermore, the support mechanism includes a fixed frame, and a guide component is fixedly installed on one side of the front end of the fixed frame close to the automatic sewing mechanism for transition guidance and limiting of curtain fabrics. A main controller is installed on one side of the fixed frame.

[0014] Through the above technical solution, the supporting mechanism mainly serves as a supporting structure, and the guide component at its front end can realize transition guidance and limitation for the end of the curtain fabric and during the movement process, so as to ensure that the curtain fabric can be accurately introduced into the clamping and conveying mechanism.

[0015] Furthermore, the clamping and conveying mechanism includes a conveying frame fixed to the top of a fixed frame, two groups of chain limit assemblies are installed in the conveying frame, both ends of the conveying frame are fixedly connected to mounting brackets, and transmission shafts are rotatably connected in the two mounting brackets, and a first reduction motor for driving the transmission shaft to rotate is installed on one of the mounting brackets, and a sprocket and an opening and closing pressure plate are fixedly installed at one end of the two transmission shafts, respectively, a transmission chain is installed between the two sprockets, and the middle part of the transmission chain is limited in the corresponding two groups of chain limit assemblies, and multiple groups of clamping assemblies for curtain fabrics are installed on the transmission chain.

[0016] Through the above technical scheme, after the end of the curtain fabric is introduced into the clamping and conveying mechanism through the guide component, during this process, the first reduction motor drives the transmission chain to operate through the corresponding transmission shaft and sprocket. Since multiple sets of clamping components are installed on the transmission chain, the sprocket drives the transmission chain to operate while the opening and closing pressure plate will also rotate synchronously, thereby driving the clamping components at the corresponding positions to open automatically, so that the curtain fabric fed in can be clamped during the movement and moved in a directional manner under the drive of the transmission chain. When the curtain fabric moves to the end of the clamping and conveying mechanism, the corresponding clamping component is automatically opened due to the pressure of the opening and closing pressure plate, so that the processed curtain falls naturally under the action of gravity, thereby automatically completing the unloading work.

[0017] Furthermore, the clamping assembly includes a lower clamping plate fixed on the transmission chain, an upper clamping plate is rotatably connected to the lower clamping plate, a torsion spring hinge is installed between the lower clamping plate and the upper clamping plate, an opening and closing pressure rod is fixedly connected to one end of the upper clamping plate, and two limit rods passing through the upper clamping plate are also fixedly connected to the lower clamping plate.

[0018] Through the above technical scheme, during specific operation, when the corresponding clamping assembly approaches the opening and closing pressure plate, since the end of the upper clamping plate is fixedly connected with the opening and closing pressure rod, during the movement, the opening and closing pressure plate will press down the opening and closing pressure rod, thereby driving the upper clamping plate to rotate on the torsion spring hinge, so that the clamping ends of the lower clamping plate and the upper clamping plate are automatically opened. In this process, the curtain fabric will also move to the position between the clamping ends of the lower clamping plate and the upper clamping plate under the traction action. When the clamping assembly is completely separated from the opening and closing pressure plate with the movement of the transmission chain, the upper clamping plate will quickly reset under the elastic action of the torsion spring hinge, thereby cooperating with the lower clamping plate to complete the clamping and fixing of the side of the curtain fabric. With the continuous clamping of multiple groups of clamping assemblies, the directional traction and transportation of the entire curtain fabric can be achieved, so as to complete the subsequent automatic cutting and sewing work.

[0019] Furthermore, the adsorption and fixing mechanism includes two porous adsorption plates fixed on a fixed frame and symmetrically arranged, there is a gap between the two porous adsorption plates, the porous adsorption plate is a hollow structure, and a plurality of evenly distributed negative pressure suction holes are opened at the front end of the porous adsorption plate. A negative pressure fan corresponding to the two porous adsorption plates is also installed in the fixed frame.

[0020] Through the above technical solution, according to the actual width design requirements, when the curtain fabric moves to the specified position, the clamping and conveying mechanism will stop working briefly. At this time, the negative pressure fan starts to work and draws air from the two porous adsorption plates through the pipe, so that negative pressure suction is generated in the porous adsorption plates. At this time, under the action of negative pressure suction, the curtain fabric at the front end of the two porous adsorption plates will be adsorbed and fixed, and tightly attached to the two porous adsorption plates, so that the subsequent longitudinal cutting mechanism can cut it longitudinally.

[0021] Furthermore, the longitudinal cutting mechanism includes a first fixed plate fixed in a fixed frame, two first vertical slide rails are fixedly connected to one side of the first fixed plate, a second reduction motor is installed at the bottom of one side of the first fixed plate, a first pulley is installed at the output end of the second reduction motor and the top of one side of the first fixed plate, a first transmission belt is installed between the two first pulleys, a first slide is slidably connected between the two first vertical slide rails, the first slide is fixed to the first transmission belt, two first horizontal slide rails are fixedly connected to one side of the first slide, a first slide seat is slidably connected between the two first horizontal slide rails, a first pushing cylinder corresponding to the first slide seat is installed on the first slide, and a vertical cutting knife is installed on the first slide seat.

[0022] Through the above technical solution, when the curtain fabric is adsorbed and fixed on the two porous adsorption plates, the vertical cutting knife is started, and the first pushing cylinder pushes the first slide and the vertical cutting knife forward, thereby quickly completing the cutting of the curtain fabric. At the same time, the second reduction motor drives the first pulley to move. Since the first slide is fixed to the first transmission belt, the first pulley drives the first slide to rise and fall synchronously as a whole during the movement, and then drives the vertical cutting knife to move up and down, thereby completing the vertical cutting of the entire curtain fabric. After the longitudinal cutting is completed, the vertical cutting knife automatically resets. In addition, a notch is provided at the corresponding position on the conveying frame, so that the vertical cutting knife can completely cut off the top of the curtain fabric, thereby completing the overall separation, and since there is a gap between each set of clamping components, it will not interfere with its cutting.

[0023] Furthermore, the transverse cutting mechanism includes a second fixed plate fixed in the fixed frame, one side of the second fixed plate is fixedly connected to two second vertical slide rails, a third reduction motor is installed at the bottom of one side of the second fixed plate, the output end of the third reduction motor and the top of one side of the second fixed plate are both installed with a second pulley, a second transmission belt is installed between the two second pulleys, a second slide is slidably installed on the two second vertical slide rails, an anti-fall chain is installed between the second fixed plate and the second slide, one side of the second slide is fixedly connected to two second horizontal slide rails, a second slide seat is slidably connected between the two second horizontal slide rails, a second pushing cylinder corresponding to the second slide seat is installed on the second fixed plate, a cutting bracket is fixedly installed at the front end of the second slide seat, two symmetrical nail-studded transmission belts are installed inside the cutting bracket, a gear synchronous drive assembly for driving the symmetrical nail-studded transmission belts to operate is installed on the cutting bracket, a transverse cutting knife for transversely cutting curtain fabrics is installed on the cutting bracket, and two groups of eight-shaped guide strips are fixedly connected to one side of the cutting bracket.

[0024] Through the above technical solution, the transverse cutting mechanism is used for transverse cutting of curtain fabrics. First, the horizontal height of the transverse cutting knife needs to be adjusted according to the design size of the curtain fabric. During specific operation, the third reduction motor drives the second slide to rise and fall through the second transmission belt. When adjusted to the specified height, the third reduction motor stops working, and the height of the second slide remains fixed. At the same time, the second push cylinder will push the entire second slide forward until it is adjusted to a suitable position. At this time, the curtain fabric is pulled by the clamping conveying mechanism, and the end of the curtain fabric will be guided into the curtain through two sets of eight-shaped guide strips. In the middle of the cutting bracket, the gear synchronous drive assembly will drive the symmetrical nailed transmission belt to work synchronously. When the curtain fabric enters the position between the symmetrical nailed transmission belts, the symmetrical nailed transmission belts will clamp the curtain fabric and drive it to move to one end. Since the symmetrical nailed transmission belts are provided with multiple groups of raised nail structures, the stability can be guaranteed during the horizontal cutting process to prevent the curtain fabric from deflecting or displacing. In addition, when the curtain fabric is in motion, the horizontal cutting knife will complete the continuous cutting of the curtain fabric, and the subsequent scraps cut will naturally droop to the ground under the action of gravity.

[0025] Furthermore, the anti-turnover mechanism includes a mounting seat fixed to one side of the cutting bracket, a servo motor is installed at the rear end of the mounting seat, the front end of the servo motor output shaft is fixedly connected to a fabric sorting disc, a lateral pushing cylinder is installed on the inner side of the front end of the mounting seat, the front end of the lateral pushing cylinder piston rod is fixedly connected to a horizontal limiting gear, a vertical pushing cylinder is installed at the bottom of the front end of the mounting seat, the top of the vertical pushing cylinder piston rod is fixedly connected to a vertical limiting gear, a feeding cylinder is installed at the top of the rear end of the mounting seat, a suction cylinder is fixedly installed at one end of the feeding cylinder piston rod, and a fabric positioning suction cup is fixedly installed at the front end of the suction cylinder piston rod.

[0026] Through the above technical scheme, after the curtain fabric completes the horizontal cutting, the curtain fabric will continue to move under the traction of the clamping and conveying mechanism. At this time, the servo motor will drive the fabric sorting disc to move synchronously, so that the bottom edge of the curtain fabric can be deflected inwardly under the drive of the fabric sorting disc. In addition, the horizontal pushing cylinder will drive the horizontal limiting tooth to move forward, so as to further limit the bottom edge of the curtain fabric. The piston rod of the vertical pushing cylinder will also drive the vertical limiting tooth to move upward, so as to prevent the bottom of the curtain fabric from turning outward. Furthermore, the fabric positioning suction cup at the front end of the piston rod of the suction cylinder will further absorb and fix the end of the curtain fabric, and under the push of the feeding cylinder, the bottom end of the curtain fabric can be accurately fed into the tape sewing assembly, so as to complete the sewing of the bottom edge.

[0027] The beneficial effects of the present invention are as follows: (1) The present invention can complete the continuous automatic cutting and sewing of curtains by designing an automatic sewing mechanism, a clamping and conveying mechanism, an adsorption and fixing mechanism, an adsorption and fixing mechanism, a transverse cutting mechanism, an anti-turning mechanism and a tape sewing assembly, thereby improving the overall production and processing efficiency; (2) The present invention can replace manual labor to complete the cutting and sewing of large quantities of curtains by designing continuous and compact processing mechanisms, which not only saves a lot of manpower and material resources, but also reduces the fatigue intensity of operators; (3) The present invention can design an automated sewing and cutting device, and the device can quickly complete the automated cutting and sewing of curtains of different sizes according to the set program without manual intervention, thereby ensuring the overall production and processing quality and the production and processing progress.

[0049] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0050] like Figure 1-Figure 20As shown, a cutting and sewing machine for curtain processing in this embodiment includes a feeding mechanism 1 for releasing curtain fabric 10, the feeding mechanism 1 includes a feeding seat 101, a cloth roller 102 for winding the curtain fabric 10 is placed on the feeding seat 101, a feeding reducer 103 for driving the cloth roller 102 to rotate is installed at the rear end of the feeding seat 101, and one side between the front and rear ends of the inner wall of the feeding seat 101 is also rotatably connected with two limiting rollers 104 for limiting the curtain fabric 10, and the feeding mechanism 1 is used for the curtain surface The material 10 is discharged at a uniform speed to ensure that the release speed of the curtain fabric 10 can be adapted to the subsequent cutting and sewing. In the actual processing process, the material discharge reducer 103 drives the cloth roller 102 to rotate, and the end of the curtain fabric 10 will pass between the two limiting rollers 104 to ensure stability during the discharge process. At the same time, it can also prevent the soft curtain fabric 10 from folding or twisting. The end of the curtain fabric 10 will be oriented and moved under the traction of the clamping and conveying mechanism 4 to ensure stability during the entire processing process.

[0051] Furthermore, in this embodiment, when the cut-to-size fabric needs to be processed, the unloading mechanism 1 may not be used, and the cut curtain fabric 10 may be directly laid flat on the automatic sewing mechanism 2 manually, and the automatic sewing process may also be completed.

[0052] For automatic sewing mechanism 2, refer to Figure 1-Figure 3 The automatic sewing mechanism 2 is mainly used for sewing the side of the curtain fabric 10. The automatic sewing mechanism 2 includes a sewing machine 201. The sewing machine 201 is provided with two groups of conveyor belts 202 for conveying the curtain fabric 10. A transmission component 203 for driving the conveyor belt 202 is installed at the rear end of the sewing machine 201. A sewing machine body 204 is installed on one side of the rear end of the sewing machine 201. Limiters 205 are installed on both sides of the top rear end of the sewing machine 201. After the curtain fabric 10 is laid flat on the sewing machine 201, the conveyor belt 202 is driven by the transmission component 203 for directional movement. In this process, the conveyor belt 202 will cooperate with the sewing speed of the sewing machine body 204 to drive the curtain fabric 10 to move accurately to ensure stability during the sewing process. In addition, limiters 205 are installed on both sides of the top rear end of the sewing machine 201. The limiters 205 can ensure the alignment and stability of the side of the curtain fabric 10 during movement.

[0053] Regarding the support mechanism 3, refer to Figure 5-Figure 6The support mechanism 3 mainly serves as a supporting structure. The support mechanism 3 includes a fixed frame 301. A guide component 302 is fixedly installed on the side of the front end of the fixed frame 301 close to the automatic sewing mechanism 2, which is used for transition guidance and limiting of the curtain fabric 10. A main controller 303 is installed on one side of the fixed frame 301. The guide component 302 at its front end can realize transition guidance and limiting of the end of the curtain fabric 10 and during the movement process to ensure that the curtain fabric 10 can be accurately introduced into the clamping and conveying mechanism 4.

[0054] Regarding the clamping and conveying mechanism 4, refer to Figure 5-Figure 11 , a clamping and conveying mechanism 4 for clamping and conveying curtain fabric 10 is installed on the top of the supporting mechanism 3; the clamping and conveying mechanism 4 includes a conveying frame 401 fixed to the top of the fixed frame 301, two groups of chain limiting components 402 are installed in the conveying frame 401, both ends of the conveying frame 401 are fixedly connected with mounting brackets 403, and transmission shafts 404 are rotatably connected in the two mounting brackets 403, and a first reduction motor 405 for driving the transmission shaft 404 to rotate is installed on one of the mounting brackets 403, and a sprocket 406 and an opening and closing pressure plate 407 are fixedly installed at one end of the two transmission shafts 404, and a transmission chain 408 is installed between the two sprockets 406, and the middle part of the transmission chain 408 is limited in the corresponding two groups of chain limiting components 402, and a plurality of groups of clamping components 409 for curtain fabric 10 are installed on the transmission chain 408. After the end of the curtain fabric 10 is introduced into the clamping and conveying mechanism 4 through the guide component 302, during this process, the first reduction motor 405 drives the transmission chain 408 to operate through the corresponding transmission shaft 404 and the sprocket 406. Since multiple groups of clamping components 409 are installed on the transmission chain 408, the sprocket 406 drives the transmission chain 408 to operate while the opening and closing pressure plate 407 will also rotate synchronously, thereby driving the clamping components 409 at the corresponding positions to open automatically, so that the curtain fabric 10 fed in can be clamped during the movement, and directed to move under the drive of the transmission chain 408. When the curtain fabric 10 moves to the end of the clamping and conveying mechanism 4, the corresponding clamping component 409 is automatically opened due to the pressure of the opening and closing pressure plate 407, so that the processed curtain falls naturally under the action of gravity, thereby automatically completing the unloading work.

[0055] Regarding the clamping assembly 409, refer to Figure 8-Figure 11The clamping assembly 409 includes a lower clamping plate 4091 fixed on the transmission chain 408, and an upper clamping plate 4092 is rotatably connected to the lower clamping plate 4091. A torsion spring hinge 4093 is installed between the lower clamping plate 4091 and the upper clamping plate 4092. An opening and closing pressure rod 4094 is fixedly connected to one end of the upper clamping plate 4092, and two limiting rods 4095 that penetrate the upper clamping plate 4092 are also fixedly connected to the lower clamping plate 4091. During specific operation, when the corresponding clamping assembly 409 approaches the opening and closing pressure plate 407, since the end of the upper clamping plate 4092 is fixedly connected to the opening and closing pressure rod 4094, during the movement, the opening and closing pressure plate 407 will press down the opening and closing pressure rod 4094, thereby driving the upper clamping plate 4092 to torsionally move. The spring hinge 4093 rotates, so that the clamping ends of the lower clamping plate 4091 and the upper clamping plate 4092 are automatically opened. In this process, the curtain fabric 10 will also move to the position between the clamping ends of the lower clamping plate 4091 and the upper clamping plate 4092 under the traction action. When the clamping assembly 409 is completely separated from the opening and closing pressure plate 407 with the movement of the transmission chain 408, the upper clamping plate 4092 will quickly reset under the elastic action of the torsion spring hinge 4093, thereby cooperating with the lower clamping plate 4091 to complete the clamping and fixing of the side of the curtain fabric 10. With the continuous clamping of multiple groups of clamping assemblies 409, the directional traction and transportation of the entire curtain fabric 10 can be achieved, so as to complete the subsequent automatic cutting and sewing work.

[0056] For the adsorption fixing mechanism 5, refer to Figure 6-Figure 13 The adsorption fixing mechanism 5 includes two porous adsorption plates 501 fixed on the fixed frame 301 and symmetrically arranged, and there is a gap between the two porous adsorption plates 501. The porous adsorption plates 501 are hollow structures, and a plurality of evenly distributed negative pressure suction holes 502 are opened at the front end of the porous adsorption plates 501. A negative pressure fan 503 corresponding to the two porous adsorption plates 501 is also installed in the fixed frame 301. According to the actual width design requirements, when the curtain fabric 10 moves to the specified position, the clamping and conveying mechanism 4 will stop working temporarily. At this time, the negative pressure fan 503 starts to work and extracts the air in the two porous adsorption plates 501 through the pipeline, so that negative pressure suction is generated in the porous adsorption plates 501. At this time, under the action of negative pressure suction, the curtain fabric 10 located at the front end of the two porous adsorption plates 501 will be adsorbed and fixed, and tightly attached to the two porous adsorption plates 501, so that the subsequent longitudinal cutting mechanism 6 can cut it longitudinally.

[0057] Regarding the longitudinal cutting mechanism 6, refer to Figure 12-14, mainly used for longitudinal cutting of curtain fabrics 10, the longitudinal cutting mechanism 6 includes a first fixed plate 601 fixed in the fixed frame 301, one side of the first fixed plate 601 is fixedly connected to two first vertical slide rails 602, a second reduction motor 603 is installed at the bottom of one side of the first fixed plate 601, the output end of the second reduction motor 603 and the top of one side of the first fixed plate 601 are both installed with a first pulley 604, a first transmission belt 605 is installed between the two first pulleys 604, a first slide 606 is slidably connected between the two first vertical slide rails 602, the first slide 606 is fixed to the first transmission belt 605, one side of the first slide 606 is fixedly connected to two first horizontal slide rails 607, a first slide seat 608 is slidably connected between the two first horizontal slide rails 607, a first push cylinder 609 corresponding to the first slide seat 608 is installed on the first slide 606, and a vertical cutting knife 610 is installed on the first slide seat 608. When the curtain fabric After the curtain fabric 10 is adsorbed and fixed on the two porous adsorption plates 501, the vertical cutting knife 610 is started, and the first pushing cylinder 609 pushes the first slide 608 and the vertical cutting knife 610 to move forward, so as to quickly complete the cutting of the curtain fabric 10. At the same time, the second reduction motor 603 drives the first pulley 604 to move. Since the first slide 606 is fixed to the first transmission belt 605, the first pulley 604 drives the first slide 606 to be lifted and lowered as a whole during the movement, and then drives the vertical cutting knife 610 to move up and down, so as to complete the vertical cutting of the entire curtain fabric 10. After the longitudinal cutting is completed, the vertical cutting knife 610 automatically resets. In addition, a notch is provided at the corresponding position on the conveying frame 401, so that the vertical cutting knife 610 can completely cut off the top of the curtain fabric 10, so as to complete the overall separation. And since there is a gap between each group of clamping components 409, it will not interfere with its cutting.

[0058] Regarding the transverse cutting mechanism 7, refer to Figure 15-Figure 20The transverse cutting mechanism 7 is used for transverse cutting of the curtain fabric 10. The transverse cutting mechanism 7 includes a second fixed plate 701 fixed in the fixed frame 301. One side of the second fixed plate 701 is fixedly connected to two second vertical slide rails 702. A third reduction motor 703 is installed at the bottom of one side of the second fixed plate 701. The output end of the third reduction motor 703 and the top of one side of the second fixed plate 701 are both installed with a second pulley 704. A second transmission belt 705 is installed between the two second pulleys 704. A second slide 706 is slidably installed on the two second vertical slide rails 702. An anti-fall chain 7 is installed between the second fixed plate 701 and the second slide 706. 07, one side of the second slide 706 is fixedly connected to two second horizontal slide rails 708, a second slide seat 709 is slidably connected between the two second horizontal slide rails 708, a second push cylinder 710 corresponding to the second slide seat 709 is installed on the second fixed plate 701, a cutting bracket 711 is fixedly installed at the front end of the second slide seat 709, two symmetrical nail-belt transmission belts 712 are installed inside the cutting bracket 711, a gear synchronous driving assembly 713 for driving the symmetrical nail-belt transmission belts 712 to operate is installed on the cutting bracket 711, a transverse cutting knife 714 for transversely cutting the curtain fabric 10 is installed on the cutting bracket 711, and one side of the cutting bracket 711 is fixed There are two groups of eight-shaped guide strips 715 connected to the curtain fabric 10. First, the horizontal height of the transverse cutting knife 714 needs to be adjusted according to the design size of the curtain fabric 10. During operation, the third reduction motor 703 drives the second slide 706 to rise and fall through the second transmission belt 705. When adjusted to the specified height, the third reduction motor 703 stops working, and the height of the second slide 706 remains fixed. At the same time, the second push cylinder 710 pushes the entire second slide 709 forward until it is adjusted to a suitable position. At this time, the curtain fabric 10 is pulled by the clamping conveying mechanism 4, and the end of the curtain fabric 10 is introduced into the cutting bracket 7 through the two groups of eight-shaped guide strips 715. 11, at this time, the gear synchronous drive assembly 713 will drive the symmetrical nail-studded transmission belt 712 to work synchronously. When the curtain fabric 10 enters the position between the symmetrical nail-studded transmission belts 712, the symmetrical nail-studded transmission belts 712 will clamp the curtain fabric 10 and drive it to move to one end. Since a plurality of groups of raised nail structures are provided on the symmetrical nail-studded transmission belts 712, stability can be ensured during the horizontal cutting process to prevent the curtain fabric 10 from deflecting or shifting. In addition, when the curtain fabric 10 is in motion, the horizontal cutting knife 714 will complete the continuous cutting of the curtain fabric 10, and the subsequent scraps cut will naturally droop to the ground under the action of gravity.

[0059] Regarding the anti-fall-over mechanism 8, refer to Figure 15-Figure 20The anti-turnover mechanism 8 includes a mounting seat 801 fixed to one side of the cutting bracket 711, a servo motor 802 is installed at the rear end of the mounting seat 801, and the front end of the output shaft of the servo motor 802 is fixedly connected with a fabric sorting disc 803, a lateral pushing cylinder 804 is installed on the inner side of the front end of the mounting seat 801, and the front end of the piston rod of the lateral pushing cylinder 804 is fixedly connected with a horizontal limiting tooth 805, a vertical pushing cylinder 806 is installed at the bottom of the front end of the mounting seat 801, and the top of the piston rod of the vertical pushing cylinder 806 is fixedly connected with a vertical limiting tooth 807, a feeding cylinder 808 is installed at the top of the rear end of the mounting seat 801, and a suction cylinder 809 is fixedly installed at one end of the piston rod of the feeding cylinder 808, and a fabric positioning suction cup 810 is fixedly installed at the front end of the piston rod of the suction cylinder 809. When the curtain fabric 10 completes the horizontal cutting, , the curtain fabric 10 will continue to move under the traction of the clamping and conveying mechanism 4. At this time, the servo motor 802 will drive the fabric arranging disc 803 to move synchronously, so that the bottom edge of the curtain fabric 10 can be deflected inwardly under the drive of the fabric arranging disc 803. In addition, the lateral pushing cylinder 804 will drive the horizontal limiting tooth 805 to move forward, thereby further limiting the bottom edge of the curtain fabric 10, and the piston rod of the vertical pushing cylinder 806 will also drive the vertical limiting tooth 807 to move upward, thereby preventing the bottom of the curtain fabric 10 from turning outward; further, the fabric positioning suction cup 810 at the front end of the piston rod of the suction cylinder 809 will further absorb and fix the end of the curtain fabric 10, and under the push of the feeding cylinder 808, the bottom end of the curtain fabric 10 can be accurately fed into the tape sewing component 9.

[0060] like Figure 1 As shown, a cloth tape sewing assembly 9 is also installed on the side of the front end of the support mechanism 3 away from the automatic sewing mechanism 2, and the cloth tape sewing assembly 9 is mainly used for sewing the bottom edge.

[0061] The working principle of this embodiment is as follows: the curtain fabric 10 to be processed is slowly released from the unloading mechanism 1. After the curtain fabric 10 is laid flat on the sewing machine bed 201, the transmission assembly 203 drives the conveyor belt 202 to move in a directional manner. During this process, the sewing machine body 204 automatically sews the sides of the curtain fabric 10.

[0062] A guide assembly 302 is installed on the fixed frame 301. The guide assembly 302 can guide and limit the end of the curtain fabric 10 and during the movement process to ensure that the curtain fabric 10 can be accurately introduced into the clamping and conveying mechanism 4. At this time, the first reduction motor 405 drives the transmission chain 408 to operate through the corresponding transmission shaft 404 and the sprocket 406. Since multiple groups of clamping assemblies 409 are installed on the transmission chain 408, the sprocket 406 drives the transmission chain 408 to operate, and the opening and closing pressure plate 407 will also rotate synchronously, thereby driving the clamping assembly 409 at the corresponding position to open automatically, so that the curtain fabric 10 fed in can be clamped during the movement, and can be directed to move under the drive of the transmission chain 408;

[0063] When the curtain fabric 10 moves to the designated position, the clamping and conveying mechanism 4 will stop working temporarily, and negative pressure suction will be generated in the porous adsorption plate 501, so that the curtain fabric 10 will be adsorbed and fixed, and tightly attached to the two porous adsorption plates 501. At this time, the vertical cutting knife 610 will move up and down, thereby completing the vertical cutting work of the entire curtain fabric 10;

[0064] The subsequent curtain fabric 10 continues to move under the traction of the clamping conveying mechanism 4, and the end of the curtain fabric 10 is guided into the middle of the cutting bracket 711 through the two sets of eight-shaped guide strips 715. During the movement of the curtain fabric 10, the transverse cutting knife 714 completes the continuous cutting of the curtain fabric 10, and the subsequent scraps cut will naturally droop to the ground under the action of gravity;

[0065] An anti-turnover mechanism 8 is provided on one side of the cutting bracket 711, which will further limit the bottom edge of the curtain fabric 10, and the fabric positioning suction cup 810 at the front end of the piston rod of the suction cylinder 809 will further absorb and fix the end of the curtain fabric 10, and under the push of the feeding cylinder 808, the bottom end of the curtain fabric 10 can be accurately fed into the cloth tape sewing component 9, and the cloth tape sewing component 9 completes the final sewing work of its bottom edge;

[0066] When the curtain fabric 10 moves to the end of the clamping and conveying mechanism 4, the corresponding clamping assembly 409 is automatically opened due to the pressing action of the opening and closing pressure plate 407, so that the processed curtain falls naturally under the action of gravity, thereby automatically completing the unloading work.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
