Description

Technical Field

[0001] This application belongs to the technical field of textile equipment, and particularly relates to a fabric roll fixing device for an automatic fabric pulling machine. Background Art

[0002] In the garment production industry, fabric pulling and cutting play a crucial role. Only regular cut pieces can be sewn into clothes that meet the specifications. If the cut pieces are irregular, even with the best sewing machines and the most excellent sewing workers, it is difficult to sew high-quality clothes. Fabric pulling is the first process in garment making, and the quality of fabric pulling determines the quality of the entire production.

[0003] Before the existing automatic fabric pulling machine performs fabric pulling and spreading, it is necessary to first transport the fabric roll. The transported fabric roll can only perform the work of fabric pulling, spreading, and cutting after being transported again by the clamping device. However, there is no corresponding fixing mechanism for the fabric roll after the initial transportation, resulting in various problems when clamping the fabric. For example, the fabric roll moves under the influence of the clamping device, resulting in clamping errors. Moreover, there is no corresponding roller to fix the fabric roll after the initial transportation, which will have a certain impact on the subsequent fabric pulling and spreading work. Summary of the Invention

[0004] The purpose of this application is to provide a fabric roll fixing device for an automatic fabric pulling machine, which can solve the above problems.

[0005] The purpose of this application is to provide a fabric roll fixing device for an automatic fabric pulling machine, including:

[0006] A frame, on which a workbench is provided;

[0007] A handling device, which is arranged on the frame and is used to transport the fabric roll;

[0008] A fabric pulling device, which is arranged on the frame and is used to stretch, flatten, and cut the fabric;

[0009] A fabric clamping device, which is arranged on the frame and is located on the side of the handling device close to the fabric pulling device. The fabric clamping device is used to receive the transported fabric roll and clamp the fabric on the fabric roll to the fabric pulling device;

[0010] Among them, a fixing device is further included, and the fixing device is arranged on the fabric clamping device and is used to fix the fabric roll transported by the handling device to the fabric clamping device.

[0011] By adopting the cloth roll fixing device of the above-mentioned automatic cloth-pulling machine, the cloth roll can be automatically transported, and the cloth can be stretched and flattened, and finally the cloth can be cut through the coordinated use of the conveying device, the cloth clamping device and the cloth pulling device. The staff is replaced by the corresponding mechanism, which reduces the workload of the staff and reduces the labor cost. Among them, before stretching the cloth, the cloth roll is fixed by setting a fixing device to prevent the cloth roll from being clamped incorrectly and improve the efficiency of stretching the cloth roll. During processing, the staff places the cloth roll on the conveying device, the conveying device transports the cloth roll to the cloth pulling device, the fixing device starts to fix the cloth, and at this time the cloth clamping device starts and fixes the cloth head on the fixed cloth roll on the cloth pulling device. The cloth pulling device stretches the cloth, and finally the cloth is cut to complete the processing of the cloth.

[0012] Furthermore, the cloth clamping device comprises:

[0013] A support base is arranged on the workbench;

[0014] A fixed frame, movably arranged on a workbench;

[0015] A rotating rod is rotatably arranged on a fixed frame, and a first driver for driving the rotating rod to rotate is also arranged on the fixed frame;

[0016] The cloth clamping structure comprises a movable rod symmetrically arranged on the rotating rod, a clamping claw arranged on the movable rod, and a second driver driving the movable rod to operate;

[0017] Wherein, the movable rod is movably arranged on the rotating rod.

[0018] When the cloth roll is fixed, the cloth head needs to be pulled out from the cloth roll, and then the pulled cloth head is towed and fixed. During the towing, the position of the movable rod is adjusted under the action of the first driver and the second driver. When it is adjusted to a suitable position, the clamping claw starts and clamps the cloth head. After the cloth head is clamped, the fixing frame moves and pulls the cloth, thereby completing the pulling work of the cloth, which is convenient for the subsequent fixing and cutting of the cloth. Before clamping, the position between the two movable rods can also be adjusted so that the distance between the movable rods is adapted to the width of the cloth roll, thereby reducing the generation of wrinkles when the clamping claw clamps the cloth.

[0019] Further: the cloth clamping device also includes a receiving platform arranged on the support seat, the receiving platform is used to receive the cloth transported by the handling device, the receiving platform is composed of a first baffle, a second baffle and a U-shaped groove between the first baffle and the second baffle, and the U-shaped groove is composed of multiple tubes.

[0020] The U-shaped groove composed of multiple pipe bodies is used to store the fabric roll. The arrangement of the pipe bodies can prevent the fabric roll from being damaged during reception. The first baffle and the second baffle located on both sides of the U-shaped groove can play a supporting and blocking role to prevent the fabric roll from falling to the outside.

[0021] Furthermore, the fixing device includes:

[0022] A first sliding rod, arranged on one side of the U-shaped groove;

[0023] A second sliding rod, arranged on the other side of the U-shaped groove and opposite to the first sliding rod;

[0024] A fitting, including a first slider arranged on the first sliding rod and slidable on the first sliding rod, and a second slider arranged on the second sliding rod and slidable on the second sliding rod;

[0025] A supporting member, including a first supporting block arranged on the first slider and a second supporting block arranged on the second slider. A first supporting roller is rotatably arranged on the first supporting block, and a second supporting roller is rotatably arranged on the second supporting block;

[0026] A driving member, including a third driver connected to the first slider and driving the first slider to move, and a fourth driver connected to the second slider and driving the second slider to move;

[0027] Wherein, a first damping mechanism connecting the first slider is arranged on the first baffle, and a second damping mechanism connecting the second slider is arranged on the second baffle.

[0028] When the fixing device fixes the fabric roll, driven by the third driver and the fourth driver, the first slider and the second slider move on the first sliding rod and the second sliding rod respectively. The first slider and the second slider move towards each other, and the distance between them gradually becomes smaller. As the first slider and the second slider move, the first supporting block and the second supporting block also move accordingly. Eventually, the distance between the first supporting roller and the second supporting roller gradually becomes smaller. When the first supporting roller and the second supporting roller are fully engaged with the fabric roll, they stop moving. The first damping mechanism and the second damping mechanism can buffer the relative movement of the first slider and the second slider respectively, and can also reduce the impact and vibration when the first supporting block and the second supporting block contact the fabric roll, ensuring the stability of fixing the fabric roll, thus ensuring the stability of the movement of the first supporting roller and the second supporting roller, and reducing the possibility of collision when the first supporting roller and the second supporting roller are engaged with the fabric roll.

[0029] Furthermore, a first collar is arranged at one end of the first slider close to the second slider, and the first collar is hinged to the first slider;

[0030] A second collar is arranged at one end of the second slider close to the first slider, and the second collar is hinged to the second slider;

[0031] One end of the first sliding rod close to the second sliding rod is provided with a first extension rod;

[0032] One end of the second sliding rod close to the first sliding rod is provided with a second extension rod, and the second extension rod is connected to the first extension rod;

[0033] Wherein, both the first extension rod and the second extension rod are arc-shaped.

[0034] When the first slider moves, the first collar will also move on the first sliding rod accordingly. Since the first collar is hinged to the first slider and the first sliding rod is provided with an arc-shaped first extension rod, when the first collar moves to the extreme position of the first sliding rod, the first collar will enter the first extension rod, and the moving angle changes. And since the first collar is connected to the first damping mechanism, when the moving angle of the first collar changes, the force in the axial direction can be dispersed to the horizontal direction, thereby buffering this movement, and further buffering the coordinated movement of the first support roller and the fabric roll, reducing the possibility of collision between the first support roller and the fabric roll.

[0035] When the second slider moves, the second collar will also move on the second sliding rod accordingly. Since the second collar is hinged to the second slider and the second sliding rod is provided with an arc-shaped second extension rod, when the second collar moves to the extreme position of the second sliding rod, the second collar will enter the second extension rod, and the moving angle changes. And since the second collar is connected to the second damping mechanism, when the moving angle of the second collar changes, the force in the axial direction can be dispersed to the horizontal direction, thereby buffering this movement, and further buffering the coordinated movement of the second support roller and the fabric roll, reducing the possibility of collision between the second support roller and the fabric roll.

[0036] In addition, the first extension rod and the second extension rod are connected and have the same structure. Therefore, the braking and buffering distances of the first collar and the second collar are the same, which can improve the accuracy and stability when fixing the fabric roll.

[0037] Further, a first mounting plate is provided on the first extension rod, a first limiting rod is vertically provided on the first mounting plate, and a first bayonet adapted to the first limiting rod is provided on the first collar;

[0038] A second mounting plate is provided on the second extension rod, a second limiting rod is vertically provided on the second mounting plate, and a second bayonet adapted to the second limiting rod is provided on the second collar;

[0039] Wherein, a first gap is formed between the first limiting rod and the first extension rod, and a second gap is formed between the second limiting rod and the second extension rod.

[0040] The first mounting plate is located at the bottom of the first extension rod, and the first limiting rod is vertically arranged on the first mounting plate. After the first collar moves onto the first extension rod, the first slider continues to move. At this time, the first collar continues to move into the first extension rod under the influence of the first slider. When the first collar moves to the extreme position, the first bayonet engages with the first limiting rod, so that the first collar maintains a state of engagement with the first limiting rod, and thus the first support roller maintains a state of engagement with the fabric roll. Similarly, the second mounting plate is located at the bottom of the second extension rod, and the second limiting rod is vertically arranged on the second mounting plate. After the second collar moves onto the second extension rod, the second slider continues to move. At this time, the second collar continues to move into the second extension rod under the influence of the second slider. When the second collar moves to the extreme position, the second bayonet engages with the second limiting rod, so that the second collar maintains a state of engagement with the second limiting rod, and thus the second support roller maintains a state of engagement with the fabric roll. During the cooperation process, the first damping structure and the second damping structure are used for buffering, ensuring the stability of the cooperation.

[0041] The setting of the first gap facilitates the passing of the first collar, avoiding the first collar being stuck between the first limiting rod and the first extension rod. The setting of the second gap facilitates the passing of the second collar, avoiding the second collar being stuck between the second limiting rod and the second extension rod.

[0042] Furthermore, the handling device includes:

[0043] A lifting mechanism, including a support frame, a conveyor belt arranged on the support frame, and a fifth driver for driving the operation of the conveyor belt;

[0044] A flipping mechanism, including a flipping bucket and a sixth driver for driving the flipping of the flipping bucket. One end of the flipping bucket is hinged to the support frame.

[0045] Wherein, one side of the support frame is connected to the frame, and a plurality of convex strips are evenly arranged on the conveyor belt.

[0046] Before transporting the fabric roll, the fabric roll to be transported needs to be placed on the flipping bucket. The flipping bucket is driven by the sixth driver and its angle is adjusted. The flipping bucket flips through the angle adjustment, moving the fabric roll inside to the conveyor belt. The conveyor belt gradually changes from being flat at the beginning to being inclined. The flat setting at the beginning can prevent the fabric roll from falling during transportation, facilitating the safe lifting of the fabric roll. The subsequent inclined setting can gradually transport the fabric roll at a lower position to a higher position. At the same time, in order to further prevent the fabric roll from falling, the inclined angle should not be too large, and a plurality of convex strips are evenly arranged on the conveyor belt. The convex strips provide support for the fabric roll, effectively preventing the fabric roll from falling during lifting.

[0047] Furthermore, the fabric pulling device includes:

[0048] The cloth guiding seat is arranged on the supporting seat;

[0049] The cloth pressing mechanism is used to fix the cloth;

[0050] The cutting mechanism is arranged on the cloth guiding seat and is used to cut the fixed cloth;

[0051] Among them, the cloth pressing mechanism includes a first cloth pressing structure arranged on the cloth guiding seat and a second cloth pressing structure arranged on the workbench.

[0052] When the cloth roll is transported to the cloth pulling device through the lifting mechanism, the fixing device starts to fix the cloth roll. After fixing, the cloth clamping device starts and fixes the cloth head on the cloth roll to the cloth pulling device. When the cloth head is fixed, the cloth guiding seat moves towards the second cloth pressing structure and fixes the cloth head on the second cloth pressing structure. Then the cloth guiding seat returns along the workbench. During the return process, the cloth is stretched and flattened on the workbench. Then the cutting mechanism cuts the stretched cloth to complete the processing.

[0053] The beneficial effects of this application are:

[0054] 1. By using the cloth roll fixing device of the above-mentioned automatic cloth pulling machine, through the coordinated use of the handling device, the cloth clamping device and the cloth pulling device, the cloth roll can be automatically transported, the cloth can be stretched and flattened, and finally the cloth can be cut. The corresponding mechanisms replace the staff, reducing the workload of the staff and lowering the labor cost. Among them, before stretching the cloth, by setting the fixing device, the cloth roll is fixed to prevent misclamping of the cloth roll and improve the efficiency of stretching the cloth roll;

[0055] 2. When the fixing device fixes the cloth roll, the first damping member mechanism and the second damping mechanism can buffer the opposite movement of the first slider and the second slider respectively, and can also slow down the impact and vibration when the first support block and the second support block contact the cloth roll, ensuring the stability of fixing the cloth roll, thereby ensuring the stability of the movement of the first support roller and the second support roller, and reducing the possibility of collision between the first support roller and the second support roller and the cloth roll;

[0056] 3. When the first collar and the second collar move to the limit position, the moving angles of the two will change. And because the first collar and the second collar are respectively connected to the first damping mechanism and the second damping mechanism, therefore, when the moving angles of the first collar and the second collar change after moving, the force in the axial direction can be dispersed to the horizontal direction, thereby buffering this movement, and further buffering the coordinated movement of the first support roller, the second support roller and the cloth roll, reducing the possibility of collision between the first support roller, the second support roller and the cloth roll.

[0075] Embodiment 2:

[0076] The embodiment of the present application provides a fabric roll fixing device for an automatic fabric spreading machine. In addition to including the above technical features, the fabric roll fixing device of the automatic fabric spreading machine in the embodiment of the present application further includes the following technical features.

[0077] As Figures 1 to 4 shown, the fabric clamping device 400 includes:

[0078] A support seat 410, arranged on the workbench 110;

[0079] A fixing frame 420, movably arranged on the workbench 110;

[0080] A rotating rod 430, rotatably arranged on the fixing frame 420, and a first driver 431 for driving the rotating rod 430 to rotate is further arranged on the fixing frame 420;

[0081] A fabric clamping structure, including movable rods 440 symmetrically arranged on the rotating rod 430, clamping claws 441 arranged on the movable rods 440, and a second driver for driving the movable rods 440 to operate;

[0082] Among them, the movable rod 440 is movably arranged on the rotating rod 430.

[0083] In the embodiment of the present application, after the fabric roll is fixed, the fabric head needs to be pulled out from the fabric roll, and then the pulled fabric head is towed and fixed. During the towing, under the action of the first driver 431 and the second driver, the position of the movable rod 440 is adjusted. When the adjustment reaches the appropriate position, the jaw 441 is activated to grip the fabric head. After gripping the fabric head, the fixing frame 420 moves to tow the fabric, thus completing the towing work of the fabric, facilitating the subsequent fixing and cutting work of the fabric. Among them, before gripping, the position between the two movable rods 440 can also be adjusted so that the distance between the movable rods 440 adapts to the width of the fabric roll, thereby reducing the generation of wrinkles when the jaw 441 grips the fabric.

[0084] Moreover, the fabric clamping device 400 further includes a receiving table 450 provided on the support base 410. The receiving table 450 is used to receive the fabric transported by the handling device 200. The receiving table 450 is composed of a first baffle 451, a second baffle 452, and a U-shaped groove 453 between the first baffle 451 and the second baffle 452. The U-shaped groove 453 is composed of multiple pipe bodies.

[0085] In some embodiments of the present application, the U-shaped groove 453 composed of multiple pipe bodies is used to store the fabric roll. The arrangement of the pipe bodies can prevent the fabric roll from being damaged during reception. The first baffle 451 and the second baffle 452 located on both sides of the U-shaped groove 453 can play a supporting and blocking role to prevent the fabric roll from falling to the outside.

[0086] Embodiment 3:

[0087] The embodiment of the present application provides a fabric roll fixing device for an automatic fabric pulling machine. In addition to including the above technical features, the fabric roll fixing device of the automatic fabric pulling machine in the embodiment of the present application further includes the following technical features.

[0088] As Figures 3 to 6 shown, the fixing device 500 includes:

[0089] A first sliding rod 510, provided on one side of the U-shaped groove 453;

[0090] A second sliding rod 520, provided on the other side of the U-shaped groove 453 and opposite to the first sliding rod 510;

[0091] A fitting, including a first slider 530 provided on the first sliding rod 510 and slidable on the first sliding rod 510, and a second slider 531 provided on the second sliding rod 520 and slidable on the second sliding rod 520;

[0092] The support member includes a first support block 540 disposed on the first slider 530 and a second support block 541 disposed on the second slider 531. A first support roller 542 is rotatably disposed on the first support block 540, and a second support roller 543 is rotatably disposed on the second support block 541;

[0093] The driving member includes a third driver 550 connected to the first slider 530 and driving the first slider 530 to move, and a fourth driver 551 connected to the second slider 531 and driving the second slider 531 to move;

[0094] Wherein, a first damping mechanism 560 connecting the first slider 530 is disposed on the first baffle 451, and a second damping mechanism 570 connecting the second slider 531 is disposed on the second baffle 452.

[0095] In the embodiment of the present application, when the fixing device 500 fixes the fabric roll, driven by the third driver 550 and the fourth driver 551, the first slider 530 and the second slider 531 move on the first slide bar 510 and the second slide bar 520 respectively. The first slider 530 and the second slider 531 move towards each other, and the distance between them gradually becomes smaller. As the first slider 530 and the second slider 531 move, the first support block 540 and the second support block 541 also move accordingly, finally making the distance between the first support roller 542 and the second support roller 543 gradually become smaller. When the first support roller 542 and the second support roller 543 are fully engaged with the fabric roll, they stop moving. The first damping member mechanism and the second damping mechanism 570 can respectively buffer the movement of the first slider 530 and the second slider 531 towards each other, and can also slow down the impact and vibration when the first support block 540 and the second support block 541 contact the fabric roll, ensuring the stability of fixing the fabric roll, thereby ensuring the stability of the movement of the first support roller 542 and the second support roller 543, and reducing the possibility of knocking when the first support roller 542 and the second support roller 543 are engaged with the fabric roll.

[0096] Embodiment 4:

[0097] The embodiment of the present application provides a fabric roll fixing device for an automatic cloth pulling machine. In addition to including the above technical features, the fabric roll fixing device of the automatic cloth pulling machine in the embodiment of the present application further includes the following technical features.

[0098] As Figures 3 to 6 shown, one end of the first slider 530 close to the second slider 531 is provided with a first collar 600, and the first collar 600 is hinged to the first slider 530;

[0099] One end of the second slider 531 close to the first slider 530 is provided with a second collar 610, and the second collar 610 is hinged to the second slider 531;

[0100] One end of the first sliding rod 510 close to the second sliding rod 520 is provided with a first extension rod 620;

[0101] One end of the second sliding rod 520 close to the first sliding rod 510 is provided with a second extension rod 630, and the second extension rod 630 is connected to the first extension rod 620;

[0102] Wherein, both the first extension rod 620 and the second extension rod 630 are arc-shaped.

[0103] In the embodiment of the present application, when the first slider 530 moves, the first collar 600 will also move on the first sliding rod 510 accordingly. Since the first collar 600 is hinged to the first slider 530 and the first sliding rod 510 is provided with an arc-shaped first extension rod 620, when the first collar 600 moves to the limit position of the first sliding rod 510, the first collar 600 will enter the first extension rod 620, and the moving angle changes. And since the first collar 600 is connected to the first damping mechanism 560, when the moving angle of the first collar 600 changes, the force in the axial direction can be dispersed to the horizontal direction, thereby buffering this movement, and further buffering the coordinated movement of the first support roller 542 and the fabric roll, reducing the possibility of collision between the first support roller 542 and the fabric roll.

[0104] When the second slider 531 moves, the second collar 610 will also move on the second sliding rod 520 accordingly. Since the second collar 610 is hinged to the second slider 531 and the second sliding rod 520 is provided with an arc-shaped second extension rod 630, when the second collar 610 moves to the limit position of the second sliding rod 520, the second collar 610 will enter the second extension rod 630, and the moving angle changes. And since the second collar 610 is connected to the second damping mechanism 570, when the moving angle of the second collar 610 changes, the force in the axial direction can be dispersed to the horizontal direction, thereby buffering this movement, and further buffering the coordinated movement of the second support roller 543 and the fabric roll, reducing the possibility of collision between the second support roller 543 and the fabric roll.

[0105] In addition, the first extension rod 620 and the second extension rod 630 are connected and have the same structure. Therefore, the braking and buffering distances of the first collar 600 and the second collar 610 are the same, which can improve the accuracy and stability when fixing the fabric roll.

[0106] Furthermore, a first mounting plate 640 is provided on the first extension rod 620, a first limiting rod 641 is vertically provided on the first mounting plate 640, and a first bayonet 642 adapted to the first limiting rod 641 is provided on the first collar 600;

[0107] A second mounting plate 650 is provided on the second extension rod 630, and a second limiting rod 651 is vertically provided on the second mounting plate 650. A second bayonet 652 adapted to the second limiting rod 651 is provided on the second collar 610;

[0108] Wherein, a first gap 660 is formed between the first limiting rod 641 and the first extension rod 620, and a second gap 670 is formed between the second limiting rod 651 and the second extension rod 630.

[0109] In some embodiments of the present application, the first mounting plate 640 is located at the bottom of the first extension rod 620, and the first limiting rod 641 is vertically provided on the first mounting plate 640. After the first collar 600 moves onto the first extension rod 620, the first slider 530 continues to move. At this time, the first collar 600 continues to move into the first extension rod 620 under the influence of the first slider 530. When the first collar 600 moves to the limit position, the first bayonet 642 cooperates with the first limiting rod 641, so that the first collar 600 is maintained in a state of cooperation with the first limiting rod 641, so that the first support roller 542 is maintained in a state of cooperation with the fabric roll. Similarly, the second mounting plate 650 is located at the bottom of the second extension rod 630, and the second limiting rod 651 is vertically provided on the second mounting plate 650. After the second collar 610 moves onto the second extension rod 630, the second slider 531 continues to move. At this time, the second collar 610 continues to move into the second extension rod 630 under the influence of the second slider 531. When the second collar 610 moves to the limit position, the second bayonet 652 cooperates with the second limiting rod 651, so that the second collar 610 is maintained in a state of cooperation with the second limiting rod 651, so that the second support roller 543 is maintained in a state of cooperation with the fabric roll. During the cooperation process, the first damping structure and the second damping structure are used for buffering, ensuring the stability of the cooperation.

[0110] The setting of the first gap 660 can facilitate the passing of the first collar 600, avoiding the first collar 600 being stuck between the first limiting rod 641 and the first extension rod 620. The setting of the second gap 670 can facilitate the passing of the second collar 610, avoiding the second collar 610 being stuck between the second limiting rod 651 and the second extension rod 630.

[0111] Embodiment 5:

[0112] The embodiment of the present application provides a fabric roll fixing device for an automatic cloth pulling machine. In addition to including the above technical features, the fabric roll fixing device of the automatic cloth pulling machine in the embodiment of the present application further includes the following technical features.

[0113] As Figure 1 and Figure 2 shown, the handling device 200 includes:

[0114] The lifting mechanism 210 includes a support frame 221, a conveyor belt 222 disposed on the support frame 221, and a fifth driver 223 for driving the operation of the conveyor belt 222;

[0115] The flipping mechanism 230 includes a flipping bucket 231 and a sixth driver 232 for driving the flipping of the flipping bucket 231. One end of the flipping bucket 231 is hinged to the support frame 221.

[0116] Wherein, one side of the support frame 221 is connected to the frame 100, and a plurality of ridges are uniformly arranged on the conveyor belt 222.

[0117] In the embodiment of the present application, before transporting the fabric roll, it is necessary to place the fabric roll to be transported on the flipping bucket 231. The flipping bucket 231 is driven by the sixth driver 232 and its angle is adjusted. The flipping bucket 231 flips through the angle adjustment, and the fabric roll inside is moved onto the conveyor belt 222. The conveyor belt 222 gradually changes from being flat at the beginning to being inclined. The flat setting at the beginning can prevent the fabric roll from falling during transportation and facilitate the safe lifting of the fabric roll. The subsequent inclined setting can gradually transport the fabric roll at a lower position to a higher position. At the same time, in order to further prevent the fabric roll from falling, the inclined angle should not be too large, and a plurality of ridges are uniformly arranged on the conveyor belt 222. The ridges provide a supporting part for the fabric roll and effectively prevent the fabric roll from falling during lifting.
