Description

Technical Field

[0001] The present application relates to the technical field of fabric cutting, and in particular to an air suction structure for a wear-resistant fabric cutting device. Background Art

[0002] Abrasion-resistant fabrics are highly abrasion-resistant and are widely used in outdoor sports, industrial protection, military equipment, and other fields. Through specialized fiber materials and processing techniques, these fabrics enhance their resistance to physical wear and tear, extending the lifespan of garments. Before garments are made, abrasion-resistant fabrics must be cut into pieces. Currently, specialized cutting devices are available to precisely cut the fabric, replacing traditional manual cutting.

[0003] When cutting fabrics, existing cutting devices generally use a suction structure to adsorb the fabrics on the working panel to fix the fabrics, so as to prevent the fabrics from shifting during the cutting process and causing cutting errors; however, the fabrics may be stacked when placed on the working panel, causing the fabrics to be uneven when adsorbed on the working panel, which will still cause errors in fabric cutting.

[0004] In view of this, the purpose of the present invention is to provide a wear-resistant suction structure for a fabric cutting device that can flatten the fabric. Utility Model Content

[0009] The stretching tubes are arranged above the working panel, and two of them are provided and arranged opposite to each other. A plurality of stretching openings are formed on the surface of the stretching tubes, and the stretching tubes are connected to the first conduit;

[0010] A driving assembly is movably connected to the stretching tube to drive the stretching tube to move and rotate;

[0011] Among them, in the material receiving state, the two stretching tubes move and rotate in the direction of approaching each other; in the material stretching state, the two stretching tubes move in the direction of moving away from each other.

[0012] During the working process, the fabric is placed on the working panel. Since two stretching tubes are provided on the working panel, the stretching tubes are connected to the first conduit, and the first conduit is connected to the vacuum pump.

When in the material receiving state, the two stretching tubes move and rotate in the direction of approaching each other, and the two ends of the fabric can be adsorbed and wound on the stretching tubes; in the material stretching state, the two stretching tubes move in the direction of moving away from each other, and the fabric can be stretched flat under the action of the stretching tubes. When the fabric is stretched flat, the stretching tubes continue to move, and the two ends of the fabric can be separated from the stretching tubes under the action of tension, so that the fabric is stretched flat and spread flat on the working panel.

[0013] Furthermore, the drive assembly includes:

[0014] A fixing seat, fixedly arranged on one side of the working panel;

[0015] A double-ended screw is rotatably mounted on a fixed seat;

[0016] A sliding rod, fixedly arranged on a fixed seat;

[0017] Two movable seats are provided and arranged opposite to each other. The movable seats are slidably arranged on the slide rod and are threadedly connected to the double-headed screw rod;

[0018] A first fixed plate, fixedly arranged on the movable base;

[0019] The rotating shaft is fixedly connected to the stretching tube and is coaxially arranged. The rotating shaft is rotatably arranged on the first fixed plate.

[0024] The rack is fixed on the fixed seat and is engaged with the outer serrations;

[0025] The ratchet ring is movably connected to the rotating shaft so that when the ratchet ring rotates toward the middle of the double-headed screw, the rotating shaft and the ratchet ring rotate synchronously.

[0026] Furthermore, a plurality of inner serrations are fixedly provided in a circumferential array on the inner circumferential surface of the ratchet ring, ratchets are rotatably provided on the rotating shaft, an elastic member is fixedly connected to the rotating shaft, and the elastic member is connected to the ratchets.

[0027] Furthermore, the first conduit is connected to the second conduit, and the second conduit is communicated with the stretching pipe through a hose.

[0028] Furthermore, a first solenoid valve is provided on the first conduit between the working panel and the second conduit, and a second solenoid valve is provided on the second conduit.

[0029] The beneficial effects of this application are:

[0030] 1. By setting up two stretching tubes, the two ends of the fabric can be wound and adsorbed on the stretching tubes. After the fabric is wound on the stretching tubes, the stretching tubes are moved toward the two ends of the fabric to stretch the fabric flat. After the fabric is stretched flat, it is spread flat and adsorbed on the working panel to avoid cutting errors caused by fabric stacking during cutting.

[0031] Second, the stretching tube and the second conduit are connected via a hose, so that the stretching tube and the second conduit are connected without affecting the movement and rotation of the stretching tube.

[0032] 3. The setting of the first solenoid valve and the second solenoid valve can intelligently control the opening and closing of the suction function of the stretching tube and the working panel. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0047] A wear-resistant fabric cutting device uses an air suction structure, comprising a working panel 2 and a material drawing tube 3 disposed above the working panel 2. The working panel 2 is constructed as a hollow plate-like structure, with a plurality of air suction ports 4 formed on the top surface of the working panel 2. A first conduit 5 is disposed below the working panel 2, one end of the first conduit 5 being connected to the internal cavity of the working panel 2 and the other end being connected to a vacuum pump. When the vacuum pump is activated, the fabric 1 can be sucked onto the working panel 2 through the air suction ports 4, thereby securing the fabric 1 and facilitating cutting.

[0048] The first conduit 5 is connected to the second conduit 6, and the second conduit 6 is connected to the stretching tube 3 through a hose 7. A first solenoid valve 8 is arranged on the first conduit 5 between the working panel 2 and the second conduit 6, and a second solenoid valve 9 is arranged on the second conduit 6. The first solenoid valve 8 and the second solenoid valve 9 can intelligently control the opening and closing of the suction function on the working panel 2 and the stretching tube 3.

[0049] There are two stretching tubes 3 and they are relatively arranged on both sides of the working panel 2 along the length direction of the working panel 2. A plurality of stretching ports 10 are formed on the surface of the stretching tube 3. When the second solenoid valve 9 is opened, the fabric 1 can be adsorbed on the stretching tube 3 through the stretching port 10; the stretching tube 3 is movably connected to the driving component 11, and the driving component 11 can drive the stretching tube 3 to move and rotate. When in the material receiving state, the driving component 11 can drive the two stretching tubes 3 to move and rotate in the direction of approaching each other. In the material receiving state, the driving component 11 can drive the two lining tubes to move in the direction of moving away from each other; in the material receiving state, the two ends of the fabric 1 are stretched as the material moves. The movement and rotation of the tube 3 can be adsorbed and wound on the stretching tube 3. In the stretching state, as the stretching tube 3 moves, the stacked part of the fabric 1 can be flattened by the two stretching tubes 3. After the fabric 1 is stretched flat, the stretching tube 3 continues to move. The part of the fabric 1 adsorbed and wound on the lining tube can be separated from the stretching tube 3 under the action of the tension. When the stretching tube 3 is completely moved out from above the fabric 1, the fabric 1 is also completely separated from the stretching tube 3, realizing the stretching of the fabric 1; after the fabric 1 is stretched flat, the first solenoid valve 8 is opened again, and the fabric 1 is adsorbed on the working panel 2 for cutting, which can avoid the cutting error of the fabric 1 caused by the stacking of the fabric 1.

[0050] Specifically, the driving assembly 11 includes a fixed seat 12, a double-headed screw 13, a sliding rod 14, a movable seat 15, a first fixed plate 16, and a rotating shaft 17; the fixed seat 12 is fixedly set on one side of the working panel 2, the double-headed screw 13 is rotatably set on the fixed seat 12, and a driving motor 25 is installed on the fixed seat 12, and the output shaft of the driving motor 25 is fixedly connected to the double-headed screw 13 to drive the double-headed screw 13 to rotate, the sliding rod 14 is fixedly set on the fixed seat 12, and two movable seats 15 are provided and arranged opposite to each other, the movable seat 15 is slidably set on the sliding rod 14, the movable seat 15 is threadedly connected to the double-headed screw 13, the first fixed plate 16 is fixedly set on the movable seat 15, the rotating shaft 17 is fixedly connected to the stretching tube 3 and is coaxially arranged, and the rotating shaft 17 is rotatably set on the first fixed plate 16;

[0051] When the driving motor 25 drives the double-headed screw 13 to rotate, the two movable seats 15 can move relative to each other along the slide bar 14 under the action of the double-headed screw 13. When the movable seat 15 moves to a position close to the middle of the slide bar 14, the driving shaft 17 rotates. The shaft 17 can drive the stretching tube 3 to rotate to absorb and wind the fabric 1 on the stretching tube 3. In the stretching state, the driving motor 25 rotates in the opposite direction, and the two movable seats 15 move away from each other to stretch the fabric 1 flat.

[0052] More specifically, the drive assembly 11 also includes a second fixed plate 18, a ratchet ring 19, external serrations 20, and a rack 21; the second fixed plate 18 is fixedly set on the movable seat 15, and the ratchet ring 19 is rotatably set on the second fixed plate 18. The ratchet ring 19 is constructed in a circular ring shape, and the external serrations 20 are provided in a plurality and are fixed in a circular array on the outer circumferential surface of the ratchet ring 19. The rack 21 is fixedly set on the fixed seat 12 and is arranged below the ratchet ring 19. The external serrations 20 on the ratchet ring 19 are meshed with the rack 21, wherein the ratchet ring 19 is movably connected to the rotating shaft 17 so that when the ratchet ring 19 rotates toward the middle of the double-headed screw 13, the ratchet ring 19 can drive the rotating shaft 17 to rotate synchronously, and when the ratchet ring 19 rotates away from the middle of the double-headed screw 13, the ratchet ring 19 will not drive the rotating shaft 17 to rotate.

[0053] More specifically, a plurality of inner serrations 22 are fixedly provided in a circular array on the inner circumferential surface of the ratchet ring 19, a ratchet 23 is rotatably provided on the rotating shaft 17, an elastic member 24 is fixedly connected to the rotating shaft 17, and the elastic member 24 is fixedly connected to the ratchet 23. The elastic member 24 is a spring, which can give the ratchet 23 a force to always rotate in the direction close to the inner serrations 22. When the ratchet ring 19 rotates in the direction close to the middle of the double-headed screw rod 13, the inner serrations 22 conflict with the ratchet teeth 23, driving the rotating shaft 17 to rotate. When the ratchet ring 19 rotates in the direction away from the middle of the double-headed screw rod 13, the inner serrations 22 squeeze the serrations to cause the ratchet teeth 23 to rotate. The inner serrations 22 will not conflict with the ratchet teeth 23, and therefore will not drive the rotating shaft 17 to rotate.

[0054] The specific working principle is as follows:

[0055] The fabric 1 is placed on the working panel 2, and the second solenoid valve 9 and the driving motor 25 are started. In the material receiving state, the driving motor 25 drives the double-headed screw 13 to rotate. The two movable seats 15 are driven by the double-headed screw 13 to move toward the middle of the double-headed screw 13. When the movable seat 15 moves, it drives the first fixed plate 16 and the second fixed plate 18 to move. The first fixed plate 16 drives the rotating shaft 17 and the stretching tube 3 to move. The second fixed plate 18 drives the ratchet ring 19 to move. During the movement of the ratchet ring 19, the outer serrations 20 engage with the rack 21. The rack 21 drives the ratchet ring 19 to rotate toward the middle of the double-headed screw 13. When the ratchet ring 19 rotates toward the middle of the double-headed screw 13, the inner serrations 22 can conflict with the ratchet teeth 23, driving the rotating shaft 17 and the ratchet ring 19 to rotate synchronously. The rotation of the stretching tube 3 is thereby realized, the stretching tube 3 moves and rotates, and the two ends of the fabric 1 are adsorbed and wound on the stretching tube 3; when the fabric is in the stretching state, the driving motor 25 rotates in the opposite direction, and the two moving seats 15 move in the direction away from the middle of the double-headed screw rod 13. At this time, the ratchet ring 19 rotates in the direction away from the middle of the double-headed screw rod 13. When the ratchet ring 19 rotates in this direction, it will not conflict with the ratchet teeth 23, thereby not driving the rotating shaft 17 to rotate, and then the stretching tube 3 will not rotate. The stretching tube 3 only moves but does not rotate. The fabric 1 will be stretched flat under the action of the stretching tube 3 and gradually decoupled from the stretching tube 3 under the action of tension; after the fabric 1 is stretched flat, the second solenoid valve 9 is closed and the first solenoid valve 8 is started. The working panel 2 adsorbs and fixes the fabric 1, and then cuts the fabric 1 to avoid cutting errors caused by the stacking of the fabric 1.
