A cutting device for clothing fabrics and its control method

Abstract

The present invention discloses a cutting device for clothing fabrics and a control method thereof, specifically relating to the technical field of fabric cutting devices, including a material table and a mounting frame. A material pulling mechanism is arranged above the material table, and a cutting mechanism and a material pressing mechanism are arranged on the mounting frame. Through the setting of the whole material mechanism, on the one hand, it can move synchronously with the material pulling mechanism, enabling the pressing rod to deflect downward and upward, thereby pressing down on both ends of the fabric after cutting to prevent the cut fabric from floating naturally. On the other hand, by changing the installation position of the support frame and the rack, the timing of the upward deflection of the pressing rod can be changed, and at the same time, by adjusting the timing of the cutting mechanism returning to the initial position, the other end of the fabric after cutting is released before the pressing rod is about to reach the position of the auxiliary material pressing mechanism and has not deflected upward. Thus, while not affecting the normal working efficiency of the device, the cut fabric is flattened and pressed down to the greatest extent, ensuring the placement position of the cut fabric.

Description

Technical Field

[0001] The present invention relates to the technical field of fabric cutting equipment, and more specifically, to a cutting equipment for clothing fabrics and a control method thereof. Background Art

[0002] The cutting of clothing fabrics refers to the process of using specific tools (such as scissors, cutting machines, etc.) to cut the fabrics required for clothing into the required shapes and sizes according to the design patterns or size requirements. In garment manufacturing, cutting is a crucial step, which directly affects the subsequent sewing work and the quality and appearance of the final product.

[0003] When the existing clothing fabric cutting equipment cuts the fabric, first, the fabric needs to be stretched to the required length by a material pulling mechanism, then the fabric is pressed by a material pressing mechanism, and finally the fabric is cut by a cutting mechanism. However, when cutting, the fabric is located above the material table and has a certain distance from the material table. After the fabric is cut, the thinner fabric will naturally fall, which will cause the fabric falling on the material table to be placed in a mess and need to be reorganized when collecting the fabric, which is rather troublesome and seriously affects the work efficiency. Moreover, the fabric will generate additional tension under the pulling action of the material pulling mechanism, and the fabric material is relatively soft. When the cutting mechanism cuts the fabric from one side, it may cause the cut to deviate and be not flat enough, affecting the cutting accuracy.

[0004] The present invention provides a cutting equipment for clothing fabrics and a control method thereof, aiming to solve the problems that after the fabric is cut, the thinner fabric will naturally fall, resulting in a mess in placement, being rather troublesome to collect and organize, seriously affecting the work efficiency, and when the fabric with tension is cut from one side, it may cause the cut to deviate and be not flat enough, affecting the cutting accuracy. Summary of the Invention

[0010] Preferably, the material aligning mechanism includes a material pressing rod. Both ends of the material pressing rod are rotatably connected to supporting plates. The other ends of the two supporting plates are fixedly connected with gears respectively. The two gears are respectively located on the sides of the two supporting plates away from each other. During the rotation of the two gears, they can drive the material pressing rod to deflect through the two supporting plates. Two supporting frames are fixedly connected to the top of the material table. The two supporting frames are symmetrically arranged. Rack bars are fixedly connected to the two supporting frames. When the two gears move following the material pulling mechanism, they can be engaged with the two rack bars.

[0011] Preferably, the material pulling mechanism includes a mounting plate. Two rotation limiting grooves are opened on the side of the mounting plate close to the mounting frame. The two gears and the corresponding supporting plates are respectively rotatably connected in the two rotation limiting grooves through rotating shafts.

The plurality of pneumatic grippers are located between the two rotation limiting grooves.

[0012] Preferably, two first electric belt guides are installed at the top of both sides of the material table. First sliders are installed on both of the first electric belt guides. The mounting plate is fixedly connected to the tops of the two first sliders. The two first electric belt guides are connected by a transmission rod. The transmission rod is used to drive the two first electric belt guides to rotate synchronously. A first motor for driving the transmission rod to rotate is installed on the mounting frame.

[0014] Preferably, the material pressing mechanism includes a material pressing frame. A material pressing plate is fixedly connected to the bottom of the material pressing frame. The material pressing plate is used to press the material when the cutting mechanism cuts the fabric. Air cylinders are installed at the bottoms of both ends of the material pressing frame. The two air cylinders are installed on the mounting frame.

[0015] A control method for a clothing fabric cutting device includes the following steps:

[0016] S1. Control the material pulling mechanism to move towards the mounting frame and clamp the fabric with multiple pneumatic grippers;

[0017] S2. Control the material pulling mechanism to drive the clamped fabric to move away from the mounting frame, pull the fabric to the required length, and make the material pressing rod deflect downward;

[0018] S3. After the fabric is pulled to the required length, control the material pressing mechanism to press one side of the fabric cutting edge;

[0019] S4. After the pressing is completed, control the cutting mechanism to cut the fabric with an electric cutting knife, and press the other side of the cut during the cutting process through the auxiliary material pressing mechanism;

[0020] S5. Control the pneumatic grippers to release the fabric, and use the material pressing rod to press down one end of the cut fabric;

[0021] S6. Control the material pulling mechanism to move towards the mounting frame, and control the cutting mechanism to return to the initial position, so that the auxiliary material pressing mechanism releases the fabric, use the material pressing rod to press down the other end of the cut fabric, and make the material pressing rod deflect upward.

[0022] Technical effects and advantages of the present invention:

[0023] 1. In summary, through the setting of the auxiliary material pressing mechanism, when the cutting mechanism cuts the fabric, it drives the driving rod to move away from above the wedge block, so that the material pressing block is no longer restricted and moves towards the top of the limit frame under the elastic rebound effect, clamping the fabric. Thus, when the electric cutting knife cuts the fabric, the material pressing mechanism cooperates to press on both sides of the fabric cut, preventing the fabric from shifting due to excessive tension, ensuring the flatness of the fabric cutting, improving the cutting quality, reducing the later trimming of the fabric, and improving the production efficiency.

[0024] 2. Through the setting of the whole material mechanism of the present invention, on the one hand, it can move synchronously with the material pulling mechanism, enabling the material pressing rod to deflect downward and upward, thereby pressing down on both ends of the fabric after cutting, preventing the cut fabric from falling naturally, avoiding messy placement of the fabric, and allowing direct collection and packing, thus improving the work efficiency. On the other hand, by changing the installation position of the support frame and the rack, the timing of the upward deflection of the material pressing rod can be changed, and at the same time, by adjusting the timing of the cutting mechanism returning to the initial position, the other end of the fabric after cutting is released before the material pressing rod reaches the position of the auxiliary material pressing mechanism and before it deflects upward. Thus, while not affecting the normal working efficiency of the equipment, the cut fabric is flattened and pressed down to the greatest extent, ensuring the placement position of the cut fabric.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1

[0040] When the fabric is pulled by the material pulling mechanism, additional tension will be generated, and the fabric material is relatively soft. When the cutting mechanism cuts the fabric from one side, it may cause the cut to deviate and be uneven, affecting the cutting accuracy.

[0041] Refer to Figure 1 and Figure 2 , a cutting device for clothing fabric according to an embodiment of the present invention includes a material table 1 and a mounting frame 2. A material pulling mechanism 3 is arranged above the material table 1, and a cutting mechanism 4 and a blank holding mechanism 5 are arranged on the mounting frame 2.

[0042] Refer to Figure 2 , Figure 6 and Figure 7, it further includes an auxiliary material pressing mechanism 6. The auxiliary material pressing mechanism 6 is arranged between the material table 1 and the cutting mechanism 4 and is used to cooperate with the material pressing mechanism 5 to press the material when the cutting mechanism 4 cuts the material. The auxiliary material pressing mechanism 6 includes a limiting frame 61. The limiting frame 61 is fixedly connected to one end of the material table 1 close to the mounting frame 2. A chute 62 is opened inside the limiting frame 61. A material pressing block 63 is slidably connected inside the chute 62. A plurality of elastic members 64 are connected between the bottom of the material pressing block 63 and the chute 62. An extrusion groove 65 is opened at the top of one end of the limiting frame 61. A wedge-shaped block 66 is fixedly connected to the top of the material pressing block 63. The position of the wedge-shaped block 66 corresponds to that of the extrusion groove 65. The wedge-shaped block 66 is slidably connected inside the extrusion groove 65. When the plurality of elastic members 64 push the material pressing block 63 to contact the inner top of the limiting frame 61, the fabric can be pressed, and the wedge-shaped block 66 can extend above the limiting frame 61.

[0043] Reference Figure 8 and Figure 10 , the cutting mechanism 4 includes a driving plate 41. A driving rod 42 is fixedly connected to the side of the driving plate 41 close to the material table 1. When the driving rod 42 is in the initial position, it is located above the wedge-shaped block 66 and can limit the wedge-shaped block 66 from protruding out of the extrusion groove 65. When the driving rod 42 contacts the wedge surface of the wedge-shaped block 66, it can squeeze the wedge-shaped block 66 to drive the material pressing block 63 to move downward inside the chute 62. The cutting mechanism 4 further includes a second electric belt guide rail 43. The second electric belt guide rail 43 is installed on the mounting frame 2. A second slider 44 is installed on the side of the second electric belt guide rail 43 close to the material table 1. The driving plate 41 is fixedly connected to the side of the second slider 44 close to the material table 1. An electric cutting knife 45 is installed at the lower part of the driving plate 41. The electric cutting knife 45 is located between the material pressing mechanism 5 and the auxiliary material pressing mechanism 6. A second motor 46 for driving the second electric belt guide rail 43 to rotate is installed on the second electric belt guide rail 43. The electric belt guide rail is a prior art and will not be elaborated.

[0044] Reference Figure 3 、 Figure 4 and Figure 12 , the material pulling mechanism 3 includes a mounting plate 31. A plurality of pneumatic grippers 34 for clamping the fabric are evenly installed on the top of the mounting plate 31. Two first electric belt guide rails 35 are installed on the top of both sides of the material table 1. First sliders 36 are installed on both of the two first electric belt guide rails 35. The mounting plate 31 is fixedly connected to the top of the two first sliders 36. The two first electric belt guide rails 35 are connected by a transmission rod 33. The transmission rod 33 is used to drive the two first electric belt guide rails 35 to rotate synchronously. A first motor 37 for driving the transmission rod 33 to rotate is installed on the mounting frame 2. The transmission rod 33 and the first motor 37 are driven by a belt.

[0045] Reference Figure 8 and Figure 9The pressing mechanism 5 includes a pressing frame 51, and a pressing plate 52 is fixedly connected to the bottom of the pressing frame 51. The pressing plate 52 is used to press the material when the cutting mechanism 4 cuts the fabric. Cylinders 53 are installed at the bottom of both ends of the pressing frame 51, and the two cylinders 53 are installed on the mounting frame 2.

[0046] In actual use, the fabric passes through the bottom of the pressing plate 52 in the pressing mechanism 5, and the first motor 37 is started to rotate forward. The first motor 37 is driven by the belt and the transmission rod 33 to drive the two first electric belt guide rails 35 to rotate synchronously. During the synchronous rotation of the two first electric belt guide rails 35, the mounting plate 31 is driven to move toward the mounting frame 2 through the first slider 36. Since the cutting mechanism 4 is in the initial position at this time, the driving rod 42 is located above the wedge block 66, which limits the wedge block 66 from extending from the extrusion groove 65. At this time, the pressing mechanism 4 is in the initial position, and the driving rod 42 is located above the wedge block 66. The material block 63 does not contact the top of the limit frame 61, and the mounting plate 31 can drive multiple pneumatic clamps 34 to pass through the inside of the limit frame 61 above the pressing block 63. At this time, the multiple pneumatic clamps 34 are started to clamp the fabric, and the first motor 37 is started to reverse. The mounting plate 31 is driven to move away from the mounting frame 2 through the two first electric belt guides 35. At this time, the fabric is clamped by the multiple pneumatic clamps 34 and synchronously follows the mounting plate 31 to move away from the mounting frame 2, thereby pulling the fabric to the required length.

[0047] After the fabric is pulled to the required length, the first motor 37 is stopped, and the cylinder 53 is controlled to drive the pressing plate 52 to move downward through the pressing frame 51 to press the fabric. At this time, the second motor 46 is started to rotate forward to drive the second electric belt guide 43 to rotate, and the electric cutting knife 45 is driven to move toward the fabric through the second slider 44 and the driving plate 41. When the driving plate 41 moves, it will drive the driving rod 42 to move, so that the driving rod 42 is moved away from the top of the wedge block 66. At this time, the pressing block 63 is no longer restricted and moves toward the top of the limit frame 61 under the rebound action of the elastic member 64 to press the fabric. When the electric cutting knife 45 cuts the fabric, it cooperates with the pressing mechanism 5 to press on both sides of the fabric incision to prevent the incision from being offset due to excessive fabric tension, thereby avoiding affecting the cutting accuracy.

[0048] To sum up, through the setting of the auxiliary pressing mechanism 6, when the cutting mechanism 4 cuts the fabric, the driving rod 42 is driven to move away from above the wedge block 66, so that the pressing block 63 is no longer restricted and moves toward the top of the limit frame 61 under the rebound action of the elastic member 64 to clamp the fabric. Therefore, when the electric cutting knife 45 cuts the fabric, the pressing mechanism 5 is cooperated to press and hold the fabric on both sides of the incision to prevent the incision from being offset due to excessive tension of the fabric, thereby ensuring the flatness of the fabric cutting, thereby improving the cutting quality, reducing the later fabric trimming, and improving production efficiency.

[0049] Embodiment 2

[0050] During actual use, since the fabric is located above the material table and has a certain distance from the material table during cutting, after the fabric is cut, the thinner fabric will naturally fall, which will cause the fabric that has fallen on the material table to be placed messily. When collecting the fabric, it needs to be reorganized, which is rather troublesome and seriously affects work efficiency. Therefore, this embodiment improves the device described in the above embodiment.

[0051] Reference Figure 3 、 Figure 4 、 Figure 5 and Figure 11 , it further includes a fabric aligning mechanism 7. The fabric aligning mechanism 7 is arranged on the material pulling mechanism 3 and is used to cooperate with the auxiliary material pressing mechanism 6 to press and align the cut fabric during the movement of the material pulling mechanism 3. The fabric aligning mechanism 7 includes a pressing rod 71. Both ends of the pressing rod 71 are rotatably connected with support plates 72. The other ends of the two support plates 72 are fixedly connected with gears 73. The two gears 73 are respectively located on the sides of the two support plates 72 away from each other. During the rotation of the two gears 73, the pressing rod 71 can be driven to deflect through the two support plates 72. Two support frames 74 are fixedly connected to the top of the material table 1. The two support frames 74 are symmetrically arranged. Rack bars 75 are fixedly connected to the two support frames 74. During the movement of the two gears 73 following the material pulling mechanism 3, they can be engaged with the two rack bars 75. Two rotation limiting grooves 32 are formed on the side of the mounting plate 31 close to the mounting frame 2. The two gears 73 and the corresponding support plates 72 are respectively rotatably connected in the two rotation limiting grooves 32 through rotating shafts. A plurality of pneumatic grippers 34 are located between the two rotation limiting grooves 32.

[0052] During actual use, during the movement of the material pulling mechanism 3, the fabric aligning mechanism 7 will move synchronously. When the mounting plate 31 drives a plurality of pneumatic grippers 34 to clamp the fabric and move away from the mounting frame 2, the mounting plate 31 will drive the pressing rod 71, the support plates 72 and the gears 73 to move synchronously. During the movement of the mounting plate 31 driving the gear 73, it will be engaged with the rack bar 75 on the support frame 74, thereby driving the gear 73 to rotate. When the gear 73 rotates, it will drive the pressing rod 71 to deflect downward through the support plate 72, so that the pressing rod 71 presses on the top of the fabric and moves following the material pulling mechanism 3;

[0053] When the cutting mechanism 4 finishes cutting the fabric, control the pneumatic gripper 34 to release the fabric. At this time, under the action of gravity, the pressure rod 71 presses down on the fabric to prevent the cut fabric from falling naturally. Then control the first motor 37 to rotate forward, so that the first electric belt guide rail 35 drives the mounting plate 31 to move towards the mounting frame 2 through the first slider 36. During the movement of the mounting plate 31, it will drive the deflected pressure rod 71 to move and flatten the fabric. At the same time, control the second motor 46 to rotate in reverse, so that the second electric belt guide rail 43 rotates and drives the electric cutting knife 45 and the driving rod 42 to return to the initial position through the driving plate 41. When the driving rod 42 contacts the wedge surface of the wedge block 66 during the process of returning to the initial position, it will squeeze the wedge block 66 to drive the pressure block 63 to compress the elastic member 64, so that the pressure block 63 moves downward inside the chute 62, releasing the other end of the fabric after being cut. The released fabric will be pressed down by the pressure rod 71, thus avoiding the natural falling phenomenon at both ends of the cut fabric, preventing the fabric from falling on the material table from being placed in a mess, and can be directly collected and packed, improving work efficiency.

[0054] It should be noted that when the material pulling mechanism 3 drives the whole material mechanism 7 deflected downward to move towards the mounting frame 2, the mounting plate 31 will drive the gear 73 to mesh with the rack 75 on the support frame 74 again, causing the gear 73 to rotate in reverse. The gear 73 will drive the pressure rod 71 to deflect upward through the support plate 72. By changing the installation positions of the support frame 74 and the rack 75, the timing of the upward deflection of the pressure rod 71 can be changed. At the same time, by adjusting the timing of the cutting mechanism 4 returning to the initial position, before the pressure rod 71 reaches the auxiliary pressure mechanism 6 position and has not deflected upward, the driving rod 42 squeezes the wedge block 66 to drive the pressure block 63 to move downward inside the chute 62, releasing the other end of the fabric after being cut. Thus, while not affecting the normal working efficiency of the equipment, the cut fabric is flattened and pressed down to the greatest extent, ensuring the placement position of the cut fabric.

[0055] In summary, through the setting of the whole material mechanism 7 of the present invention, on the one hand, it can move synchronously with the material pulling mechanism 3, enabling the pressure rod 71 to deflect downward and upward, thereby pressing down on both ends of the cut fabric, preventing the cut fabric from falling naturally, avoiding the fabric from being placed in a mess, and can be directly collected and packed, thus improving work efficiency. On the other hand, by changing the installation positions of the support frame 74 and the rack 75, the timing of the upward deflection of the pressure rod 71 can be changed. At the same time, by adjusting the timing of the cutting mechanism 4 returning to the initial position, the other end of the fabric after being cut is released before the pressure rod 71 reaches the auxiliary pressure mechanism 6 position and has not deflected upward. Thus, while not affecting the normal working efficiency of the equipment, the cut fabric is flattened and pressed down to the greatest extent, ensuring the placement position of the cut fabric.
