Description

Technical Field

[0001] This utility model relates to the field of fabric cutting technology, specifically to an ultrasonic automatic fabric pulling and slitting cross-cutting machine. Background Technology

[0002] Cleanroom wipes have a soft surface, making them easy to wipe sensitive surfaces. They do not shed fibers when rubbed and have excellent absorbency and cleaning efficiency. Therefore, they are used in semiconductor production lines for chips, microprocessors, disk drives, LCD displays, circuit board production lines, precision instruments, and cleanrooms. Cleanroom wipes are usually produced in a large roll with a wide width, and need to be cut into smaller rolls using a slitting machine for easier use.

[0003] However, existing slitting machines generally use sharp blades for cutting. When the fabric is driven by a motor and passes through the blades, it is cut into multiple strips of narrow width by the blades. The strips are then rolled into rolls for easy use. However, during the cutting process, the cut edges produce a lot of lint that floats in the working environment due to the looseness of the fabric, which directly affects the working environment. In addition, the uneven cut edges and fuzzy edges are unsightly and have poor tensile strength, which limits their application.

[0004] Therefore, we propose an ultrasonic automatic fabric spreading and slitting cross-cutting machine to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an ultrasonic automatic fabric spreading and slitting cross-cutting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic automatic fabric pulling, slitting, and cross-cutting machine, comprising: a feeding trolley, a fixed material trolley, an ultrasonic slitting system, a pulling system, a receiving and sorting workbench, and a central control unit. The ultrasonic slitting system is equipped with several ultrasonic longitudinal slitting blades and a set of ultrasonic cross-cutting components. The feeding trolley is connected to the fixed material trolley, the fixed material trolley is connected to the ultrasonic slitting system, the ultrasonic slitting system is connected to the pulling system, the pulling system is connected to the receiving and sorting workbench, and the central control unit is installed on the ultrasonic slitting system.

[0007] Preferably, the ultrasonic slitting system includes a frame, with a cutting rod and a conveying rod arranged at the feed inlet in the middle of the frame. The cutting rod is equipped with several sets of rotating double-welded wire single cutters, rotating single cutters and rotating pattern cutters, and the cutting rod is connected to a drive structure.

[0008] Preferably, a plurality of first linear cylinders are movably mounted on the frame. The lateral position of the first linear cylinders is adjustable. The telescopic end of the first linear cylinder is fixedly connected to an ultrasonic longitudinal slitting knife. The ultrasonic longitudinal slitting knife cuts the fabric with a rotating double-welded wire single cutter, a rotating single cutter, and a rotating pattern cutter, respectively.

[0009] Preferably, an ultrasonic cross-cutting assembly is provided at the material outlet of the frame. The ultrasonic cross-cutting assembly includes a linear servo module perpendicular to the fabric's forward direction. The linear servo module is driven and connected to a second linear cylinder. The telescopic end of the second linear cylinder is fixedly connected to an ultrasonic cross-cutting blade. The ultrasonic cross-cutting assembly also includes a linear guide rail. A rack is provided on the linear guide rail. A conveyor belt is also provided on the linear guide rail. The conveyor belt is connected to a servo drive structure. A moving block is fixedly installed on the conveyor belt. A transverse rotary cutter and a gear are rotatably installed on the moving block. The transverse rotary cutter and the gear are coaxially fixedly connected. The gear meshes with the rack.

[0010] Preferably, the discharge port of the frame is further provided with a first clamping and traction assembly, which includes a fixed top plate and a lifting pressure plate, with a fourth linear cylinder connected to both ends of the pressure plate.

[0011] Preferably, the frame is further provided with a clamping assembly, which is located at the subsequent station of the first clamping and traction assembly. The clamping assembly includes two parallel clamping plates, and each clamping plate is connected to a fifth linear cylinder at both ends. The fifth linear cylinder drives the clamping plate to clamp the fabric.

[0012] Preferably, the material pulling system includes a conveying component and a transfer component, and the transfer component is provided with a second clamping and traction component.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Using ultrasonic longitudinal slitting blades and ultrasonic transverse cutting components, the fibers are melted by high-frequency vibration, realizing non-contact cutting of cleanroom cloth. The cut edges are flat and burr-free, effectively avoiding the lint pollution generated by traditional mechanical cutting tools, meeting the environmental requirements of cleanrooms such as semiconductor and precision instrument manufacturing, while improving the tensile strength and aesthetics of the cloth. 2. The system integrates a feeding cart, a fixed-position cart, an ultrasonic slitting system, a material pulling system, and a receiving and sorting workbench, with each module operating in tandem through a central control unit. The entire process of fabric preparation, from slitting and cross-cutting to receiving, is automated, reducing manual intervention, significantly improving production efficiency, and minimizing operational errors. 3. The ultrasonic cross-cutting component features an innovative design with a linear servo module and a collaborative mechanism between the transverse rotating cutter. The servo drive structure drives the transverse rotating cutter via a conveyor belt. The meshing of gears and racks enables the transverse rotating cutter to rotate, ensuring that the blade is always perpendicular to the material during the cross-cutting process, thus improving cutting accuracy and speed. Combined with the synchronous action of the ultrasonic cross-cutting blade, it achieves efficient and burr-free transverse cutting. 4. The first clamping and traction component ensures stable tension of the fabric after slitting by lifting and clamping the pressure plate and the top plate. The clamping component uses double clamps and linear cylinders to apply pressure in both directions to firmly fix the fabric and prevent it from shifting during cross-cutting. The second clamping and traction component of the pulling system accurately moves the slit fabric pieces to ensure smooth continuous operation. Attached Figure Description

[0017] Please see Figure 1-9 This utility model provides a technical solution: an ultrasonic automatic fabric pulling, slitting and cross-cutting machine, including: a feeding cart 1, a fixed material cart 2, an ultrasonic slitting system 3, a material pulling system 4, a receiving and sorting workbench 5 and a central control unit 6. The ultrasonic slitting system 3 is equipped with a plurality of ultrasonic longitudinal slitting blades 34 and a set of ultrasonic cross-cutting components 35. The feeding cart 1 is connected to the fixed material cart 2, the fixed material cart 2 is connected to the ultrasonic slitting system 3, the ultrasonic slitting system 3 is connected to the material pulling system 4, the material pulling system 4 is connected to the receiving and sorting workbench 5, and the central control unit 6 is installed on the ultrasonic slitting system 3. The entire equipment is controlled by the central control unit 6. The fabric is fed from the feeding car 1 to the fixed car 2. The fixed car 2 feeds the fabric to the ultrasonic slitting system 3. The ultrasonic longitudinal slitting knife 34 and the ultrasonic transverse cutting component 35 slit the fabric and cut it into blocks, which are then transferred to the material pulling system 4. The material pulling system 4 transports the slit fabric to the receiving and sorting workbench 5 for collection and sorting.

[0018] The ultrasonic slitting system 3 includes a frame 31. A cutting roller 32 and a conveying roller 36 are arranged at the feed inlet in the middle of the frame 31. Several sets of rotating double-welded wire single-cutting blades 321, rotating single-cutting blades 322 and rotating decorative cutting blades 323 are arranged on the cutting roller 32. The cutting roller 32 is connected to a drive structure, which drives the rotating double-welded wire single-cutting blades 321, rotating single-cutting blades 322 and rotating decorative cutting blades 323 to rotate. The rotating double-welded wire single-cutting blades 321, rotating single-cutting blades 322 and rotating decorative cutting blades 323 achieve different cutting effects respectively. Several first linear cylinders 33 are movably mounted on the frame 31. The lateral position of the first linear cylinders 33 is adjustable. The telescopic end of the first linear cylinders 33 is fixedly connected to the ultrasonic longitudinal slitting knife 34. The first linear cylinders 33 drive the ultrasonic longitudinal slitting knife 34 to descend. The ultrasonic longitudinal slitting knife 34, together with the rotating double-welded wire single cutter 321, the rotating single cutter 322 and the rotating pattern cutter 323, cuts the fabric in the forward direction and divides the fabric into several strips. The ultrasonic longitudinal slitting knife 34 moves to different cutting positions to achieve different slitting effects.

[0019] An ultrasonic cross-cutting assembly 35 is provided at the material outlet of the frame 31. The ultrasonic cross-cutting assembly 35 includes a linear servo module perpendicular to the fabric forward direction. The linear servo module is driven and connected to a second linear cylinder 351. The telescopic end of the second linear cylinder 351 is fixedly connected to an ultrasonic cross-cutting blade 353. The ultrasonic cross-cutting assembly 35 also includes a linear guide rail 354, on which a rack 358 is provided, and on which a conveyor belt 357 is also provided. The conveyor belt 357 is connected to a servo drive structure 356, and a moving block is fixedly installed on the conveyor belt 357. A transverse rotary cutter 355 and a gear 359 are rotatably installed on the moving block. The transverse rotary cutter 355 and the gear 359 are coaxially fixedly connected, and the gear 359 meshes with the rack 358. A linear servo module drives the ultrasonic cross-cutting blade 353 to move laterally. A synchronous servo drive structure 356 drives the transverse rotary cutter 355 to move laterally via a conveyor belt 357. The ultrasonic cross-cutting blade 353 and the transverse rotary cutter 355 work together to transversely cut the slit fabric into blocks. As the transverse rotary cutter 355 moves, the gear 359 drives the transverse rotary cutter 355 to rotate through its interaction with the rack 358.

[0020] The discharge port of the frame 31 is also equipped with a first clamping and traction assembly 39. The first clamping and traction assembly 39 includes a fixed top plate 393 and a lifting pressure plate 392. The pressure plate 392 descends and cooperates with the top plate 393 to clamp the fabric. The two ends of the pressure plate 392 are connected to a fourth linear cylinder 391, which drives the pressure plate 392 to rise and fall.

[0021] The frame 31 is also equipped with a clamping assembly 37, which is located at the subsequent station of the first clamping traction assembly 39. The clamping assembly 37 includes two parallel clamping plates 371, and each clamping plate 371 is connected to a fifth linear cylinder 372 at both ends. The fifth linear cylinder 372 drives the clamping plate 371 to clamp the fabric.

[0022] The material pulling system 4 includes a conveying component and a transfer component 41. The transfer component 41 is equipped with a second clamping and traction component 42. The transfer component 41 drives the second clamping and traction component 42 to move closer to the outlet of the ultrasonic slitting system 3, clamp the fabric, and then retreat to the top of the conveying component. The fabric is then released, and the fabric block is transferred by the conveying component to the receiving and sorting workbench 5.

[0023] Working principle: The feeding trolley 1 pushes the fabric roll to the fixed trolley 2. One end of the fabric passes through the fixed trolley 2 and then through the ultrasonic slitting system 3, where it is clamped by the second clamping and traction component 42. The fabric travels a certain distance with the second clamping and traction component 42. During this process, the ultrasonic longitudinal slitting blade 34 descends to slit the fabric. After slitting, the clamping component 37 and the first clamping and traction component 39 clamp the slit portion of the material. The ultrasonic transverse cutting component 35 is activated, and the ultrasonic transverse cutting blade 353 and the transverse rotating cutting blade 355 work together to cut the slit fabric into blocks. The clamping component 37 releases the slit fabric, and the second clamping and traction component 42 retracts, placing the slit fabric onto the transfer component 41 and sending it to the receiving and sorting workbench 5. Then the second clamping and traction assembly 42 advances through the clamping assembly 37 to clamp the fabric head at the first clamping and traction assembly 39, and performs the second round of cutting.
