Description

Technical Field

[0001] This utility model relates to the field of cutting technology, and in particular to a rapid cutting device for fabric processing. Background Technology

[0002] Fabric cutting is a crucial step in the processing of textile products such as clothing and home textiles, and its efficiency directly affects the overall production efficiency of subsequent sewing processes. Currently, the industry commonly uses cutting tables for fabric cutting operations. Especially for large, wide fabrics in a rolled-up state, they must first be unfolded and laid flat on the cutting table before being manually positioned and cut. This process typically includes multiple steps such as spreading the fabric, flattening, fixing, and cutting, among which spreading and flattening are important prerequisites for ensuring cutting accuracy.

[0003] However, existing cutting tables still suffer from significant operational dependence and efficiency bottlenecks when cutting rolled-up fabric. Taking the common fabric spreading operation as an example, it typically requires two workers to work together, simultaneously pulling one end of the fabric to the other end of the cutting table, repeatedly adjusting to ensure the fabric is flat. After spreading, the worker must return to the starting position of the cutting table to operate the cutting blades and then repeat the spreading process. This operational mode not only consumes a large amount of manpower but also slows down the production pace, affecting cutting efficiency.

[0004] To address this, we propose a rapid cutting device for fabric processing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid cutting device for fabric processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid cutting device for fabric processing, comprising a cutting bed body and an industrial control integrated machine, wherein a U-shaped frame is fixedly connected to one end of the cutting bed body, and the industrial control integrated machine is fixedly connected to one side outer wall of the U-shaped frame, and cutting blade assemblies are fixedly connected to the top and bottom ends of the U-shaped frame, and the two cutting blade assemblies are matched.

[0007] A crossbar is fixedly connected inside the spiral frame, and a pressure plate is provided above the crossbar. Both the crossbar and the pressure plate are provided with several toothed grooves on one side of the cutting blade assembly. An adjustable extrusion assembly is installed between the spiral frame and the pressure plate.

[0008] The top of the cutting bed body is symmetrically and fixedly connected to two guide rails, and the top of the two guide rails are slidably connected to a gantry frame. An electric transverse movement assembly is installed between the gantry frame and the cutting bed body.

[0009] The outer surface of the portal frame is fixedly connected to a number of toothed pneumatic clamping components on one side of the U-shaped frame, and the toothed pneumatic clamping components are matched with the tooth grooves.

[0010] Furthermore, each of the two cutting blade assemblies includes two long cylinders, which are fixedly connected to the U-shaped frame. The movable ends of the two long cylinders are both set through the U-shaped frame and are fixedly connected to a mounting base. The cutting blade body is fixedly connected to the side of the mounting base near the middle of the U-shaped frame. The two cutting blade bodies can cooperate to cut the fabric.

[0011] Furthermore, the inner walls on both sides of the U-shaped frame are fixedly connected with first slide rails, and the first slide rails are slidably connected to the pressure plate. The first slide rails have a limiting effect on the pressure plate, which can ensure the stability of the pressure plate movement.

[0012] Furthermore, the adjustable extrusion assembly includes a hand-tightening screw that passes through the U-shaped frame and is threadedly connected to it. A movable plate is rotatably connected to the bottom of the hand-tightening screw. Several springs are evenly fixedly connected to the bottom of the movable plate, and the springs are fixedly connected to the top of the pressure plate. Two guide rods are symmetrically fixedly connected to the top of the movable plate, and the guide rods pass through the U-shaped frame and are slidably connected to it. The guide rods limit the movement of the movable plate, ensuring the stability of its movement.

[0013] Furthermore, the electric transverse assembly includes two stepper motors, which are respectively fixedly connected to the inner cavities on both sides of the portal frame. The drive ends of the two stepper motors are fixedly connected to gears, which are rotatably connected to the portal frame. The bottoms of the two gears are meshed with racks, which are fixedly connected to the top of the cutting bed body and can drive the portal frame to move.

[0014] Furthermore, each of the aforementioned toothed pneumatic clamping components includes two short cylinders, which are fixedly connected to the outer wall of one side of the portal frame in a mirror image. The movable ends of the two short cylinders are fixedly connected to movable seats, and the movable seats are fixedly connected to several clamping teeth on one side of the U-shaped frame. The clamping teeth match the tooth grooves. The two short cylinders, in conjunction with the movable seats and clamping teeth, can clamp the ends of the fabric.

[0015] Furthermore, the two movable seats are slidably connected to a second slide rail, and the second slide rail is fixedly connected to the gantry frame. The second slide rail has a limiting function for the movable seats, which can ensure the stability of the movement of the movable seats.

[0016] The beneficial effects of this utility model are:

[0017] In use, this utility model achieves continuous cyclic operation of automatic fabric clamping, pressing and fixing, and cutting by using a U-shaped frame, adjustable extrusion components, toothed pneumatic clamping components, and electric transverse components. It replaces the traditional fabric pulling and return operation that relies entirely on manual labor. Cutting can be completed after a single fabric laying, greatly reducing manpower and time consumption and significantly improving cutting efficiency. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-6 As shown, a rapid cutting device for fabric processing is disclosed, comprising a cutting bed body 1 and an industrial control integrated computer 2. One end of the cutting bed body 1 is fixedly connected to a U-shaped frame 3, and the industrial control integrated computer 2 is fixedly connected to the outer wall of one side of the U-shaped frame 3. Cutting knife assemblies are fixedly connected to the top and bottom ends of the U-shaped frame 3, and the two cutting knife assemblies are matched. Each cutting knife assembly includes two long cylinders 16, and the long cylinders 16 are fixedly connected to the U-shaped frame 3. The movable ends of the two long cylinders 16 are both set through the U-shaped frame 3 and are fixedly connected to a mounting base 18. A cutting knife body 17 is fixedly connected to the side of the mounting base 18 near the middle of the U-shaped frame 3. The long cylinders 16 can be SC series standard cylinders, which are fastened to the U-shaped frame 3 by flanges and bolts. Their piston rods pass through the reserved holes on the U-shaped frame 3. The cutting knife body 17 is a straight blade made of cemented carbide and is fixed to the mounting base 18 by pressure plate screws.

[0029] A crossbar 5 is fixedly connected inside the U-shaped frame 3. A pressure plate 10 is provided above the crossbar 5. First slide rails 6 are fixedly connected to the inner walls of both sides of the U-shaped frame 3, and the first slide rails 6 are slidably connected to the pressure plate 10. Several toothed grooves 8 are opened on one side of the cutting blade assembly of the crossbar 5 and the pressure plate 10. An adjustable extrusion assembly is installed between the U-shaped frame 3 and the pressure plate 10. The adjustable extrusion assembly includes a hand-tightening screw 15, which passes through the U-shaped frame 3 and is threadedly connected to the U-shaped frame 3. A movable plate 23 is rotatably connected to the bottom of the hand-tightening screw 15. The bottom of the movable plate 23 is evenly fixed. Several springs 9 are connected and fixedly connected to the top of the pressure plate 10. Two guide rods 7 are symmetrically fixedly connected to the top of the movable plate 23. The guide rods 7 pass through the U-shaped frame 3 and are slidably connected to the U-shaped frame 3. The hand-tightening screw 15 consists of a screw and a handwheel. The screw's thread helix angle is smaller than the friction angle, which gives the screw a self-locking ability and can prevent it from shifting due to vibration or load. The hand-tightening screw 15 is rotatably connected to the movable plate 23 through a bearing seat. The bearing seat is fixed to the movable plate 23, and the inner ring of the bearing inside the bearing seat is fixedly sleeved on the outer surface of the hand-tightening screw 15.

[0030] Two guide rails 21 are symmetrically fixedly connected to the top of the cutting bed body 1. A portal frame 4 is slidably connected to the top of the two guide rails 21. An electric transverse assembly is installed between the portal frame 4 and the cutting bed body 1. The electric transverse assembly includes two stepper motors 20, which are fixedly connected to the inner cavities on both sides of the portal frame 4. Gears 19 are fixedly connected to the drive ends of the two stepper motors 20, and the gears 19 are rotatably connected to the portal frame 4. A rack 2 is meshed with the bottom of each gear 19. 2. The rack 22 is fixedly connected to the top of the cutting bed body 1. The guide rail 21 is preferably a heavy-duty linear guide rail, which is fixed parallel to both sides of the table surface of the cutting bed body 1 by bolts. It supports and guides the movement of the gantry frame 4. The stepper motor 20 is installed in the closed cavity on both sides of the gantry frame 4 through the motor mount, which plays a protective role. The bottom of the gantry frame 4 is designed to be open, which is conducive to heat dissipation and the installation of the gear 19. The gear 19 is a steel gear, which is tightly fitted to the output shaft of the stepper motor 20 by key connection and supported by the bearing seat on the gantry frame 4.

[0031] The outer surface of the portal frame 4 is fixedly connected to a number of toothed pneumatic clamping components on one side of the U-shaped frame 3. The toothed pneumatic clamping components match the toothed grooves 8. Each of the toothed pneumatic clamping components includes two short cylinders 13. The two short cylinders 13 are fixedly connected to the outer wall of one side of the portal frame 4 in a mirror image. The movable ends of the two short cylinders 13 are fixedly connected to movable seats 11. The two movable seats 11 are fixedly connected to a number of clamping teeth 12 on one side of the U-shaped frame 3. The clamping teeth 12 match the toothed grooves 8. The two movable seats 11 are slidably connected to a second slide rail 14. The second slide rail 14 is fixedly connected to the portal frame 4. The short cylinders 13 are small and compact cylinders (such as the SDA series) and are fixed to the vertical surface of the portal frame 4 by mounting plate bolts.

[0032] The industrial control all-in-one computer 2 is electrically connected to the long cylinder 16, the short cylinder 13, and the stepper motor 20, which is beneficial for controlling the overall operation.

[0033] Working principle: The operator pulls one end of the fabric roll 24 out from the unwinding mechanism and places it on the crossbar 5. Then, the operator rotates the hand screw 15 of the adjustable extrusion assembly to push the movable plate 23 to compress the spring 9, thereby driving the pressure plate 10 to move down and press the fabric between the pressure plate 10 and the crossbar 5. The toothed groove 8 is reserved for subsequent clamping.

[0034] The industrial control all-in-one computer 2 controls the start of the electric transverse movement assembly: the stepper motor 20 drives the gear 19 to rotate along the rack 22 fixed to the cutting bed, which in turn drives the gantry frame 4 to move along the guide rail 21, causing the toothed pneumatic clamping assembly to move to the end of the fabric, so that the clamping teeth 12 are located at the tooth groove 8. Then, the short cylinder 13 operates, pushing the movable seat 11 to move along the second slide rail 14, so that the upper and lower rows of clamping teeth 12 pass through the tooth groove 8 and bite and clamp the pressed end of the fabric. Subsequently, under the action of the electric transverse movement assembly, the gantry frame 4 moves the clamping teeth 12 and the clamped fabric, automatically moving to the far end of the cutting bed to complete the fabric spreading and flattening.

[0035] Once the fabric is stretched to the predetermined length, the cutting assembly is activated: the long cylinders 16 located at the top and bottom of the loop frame 3 synchronously push the mounting base 18 and the cutting blade body 17 to move towards each other, performing synchronous double-sided cutting on the fabric section that has been stretched and laid flat on the cutting bed. After the cutting is completed, the gantry frame 4, under the action of the electric transverse component, moves the clamping teeth 12 and the clamped fabric to continue moving a distance, allowing the fabric end that was just cut to completely detach from the loop frame 3. Then, the short cylinder 13 drives the movable seat 11 away from the fabric, and the clamping teeth 12 release.

[0036] Then repeat the above steps of spreading, flattening, and cutting the fabric.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
