Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and in particular to an adaptive pressing high-precision multi-layer cutting machine. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth, is a flexible textile material made by bonding and carding fibers. It possesses numerous advantages such as breathability, moisture resistance, flexibility, environmental friendliness, and cost-effectiveness, and is widely used in medical and health care, household goods, industrial protection, packaging materials, and many other fields. With the continuous diversification and customization of market demands, the application scenarios for nonwoven fabrics are becoming increasingly segmented. Different products have significantly different requirements for the size, shape, and cutting specifications of nonwoven fabrics. Flexible, multi-specification, and precise cutting processing has become a core process in nonwoven fabric production, directly determining the quality and applicability of the finished product.

[0003] Currently, the cutting equipment used in nonwoven fabric production and processing is mostly traditional fixed-station cutting machines. The overall cutting mode is rigid and monotonous, with obvious technical limitations, making it difficult to adapt to diversified production needs. Existing cutting equipment adopts a fixed installation structure and a fixed cutting program. The cutting station and cutting trajectory are all preset fixed parameters, which can only complete standardized cutting operations of a single specification and fixed size. It cannot flexibly adjust the cutting parameters according to the processing needs of different types and sizes of nonwoven fabrics, and cannot adapt to multi-specification and customized nonwoven fabric cutting production scenarios, resulting in extremely poor equipment versatility.

[0004] Meanwhile, traditional cutting machines operate on a single, fixed method, capable only of basic straight-line cutting and unable to perform precise cutting of irregular shapes, multiple sizes, and multiple points. When faced with the production demands of customized nonwoven fabric products, they cannot adapt to diverse cutting processes, often requiring equipment replacement or manual adjustments. This not only significantly reduces the overall production efficiency of nonwoven fabrics and increases labor and time costs, but also easily leads to problems such as cutting deviations, inconsistent dimensions, and uneven cuts, severely affecting the precision and batch consistency of finished nonwoven fabrics. Furthermore, existing cutting equipment cannot automatically adjust the pressure angle and cutting depth of the cutting blades when cutting multi-layer nonwoven fabrics. Fabric deviation during transport can easily occur, resulting in inconsistent dimensions across multiple layers, rough edges, or uneven cuts, failing to guarantee the precision stability and batch consistency of multi-layer cutting.

[0005] Therefore, how to develop an automated cutting device that can flexibly adjust the guide angle and cutting position and adapt to the cutting of nonwoven fabrics of various specifications is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] The technical problem this invention aims to solve is that the guide angle and cutting position of existing nonwoven fabric cutting equipment are not adjustable, making it unable to adapt to the precise cutting needs of multi-specification and customized nonwoven fabrics, resulting in poor versatility and unstable precision during multi-layer cutting.

[0007] The technical solution adopted by the present invention to solve its technical problem is: an adaptive pressure high-precision multi-layer cutting machine, including a main frame, an electrically controlled rotating guide frame and an arc-shaped guide rail matching the electrically controlled rotating guide frame are movably mounted on the outer wall of the main frame, an upper electrically controlled feeding wheel assembly is provided at the upper opening of the electrically controlled rotating guide frame, a lower electrically controlled discharge wheel assembly is provided at the lower opening of the electrically controlled rotating guide frame, a position-adjustable flip magnetic control cutting knife assembly is installed on the electrically controlled rotating guide frame, and an optical positioning probe is installed on the side wall of the position-adjustable flip magnetic control cutting knife assembly.

[0008] Furthermore, the electrically controlled rotating guide frame is movably assembled with the main frame through the end mounting shaft. The electrically controlled rotating guide frame includes a flip frame with a guide sliding block on the control surface and an angle adjustment support rod movably mounted on the back of the main frame. The guide sliding block of the flip frame passes through the arc-shaped guide rail and is connected to the extended end of the angle adjustment support rod.

[0009] Furthermore, the upper-mounted electronically controlled feeding wheel assembly includes an upper-mounted assembly frame fixed on both sides of the upper opening of the flipping frame and an upper-mounted drive wheel installed within the upper-mounted assembly frame.

[0010] Furthermore, the lower electrically controlled discharge wheel assembly includes a lower assembly frame fixed on both sides of the lower opening of the flipping frame and a lower drive wheel installed in the lower assembly frame.

[0011] Furthermore, symmetrical inner adjustment grooves are provided on the inner walls of both sides of the flip frame, and the position-adjustable flip magnetic control cutting blade assembly is slidably installed on both sides inside the flip frame.

[0012] Furthermore, the position-adjustable flip magnetic control cutting blade assembly includes a sliding adjustment frame with sliding adjustment blocks on both sides, an adjustment support rod fixed on the outer surface of the flip frame, a flip control frame hinged to the inner side of the sliding adjustment frame, a flip support rod hinged to the outer side of the sliding adjustment frame, a telescopic control frame slidably installed inside the flip control frame, a detachable cutting blade installed on one side of the telescopic control frame, and an electromagnetic spring assembly for controlling the telescopic control frame.

[0013] Furthermore, the extended end of the flip support rod is movably connected to the side wall of the flip control frame, and the flip support rod adjusts the angle of the flip control frame by extending and retracting.

[0014] Furthermore, the optical positioning probe is fixedly mounted on the side wall of the sliding adjustment frame.

[0015] Furthermore, the electromagnetic spring assembly includes an electromagnet installed inside the flip control frame and an iron spring controlled by the electromagnet, and the telescopic control frame is connected to the end of the iron spring via a lateral control rod.

[0016] Furthermore, the two sides of the flip frame are hinged with flip-type closed covers.

[0017] The beneficial effects of this invention are as follows: By adjusting the guide angle of the electrically controlled rotating guide frame along the arc-shaped guide rail, the fabric feeding direction can be flexibly adapted to different cutting process requirements, solving the technical problems of existing equipment where the guide angle is not adjustable and cannot adapt to multi-specification cutting; by using a position-adjustable flip-type magnetic control cutting blade assembly, the cutting position can be adjusted laterally and the cutting angle can be flipped, and the electromagnetic spring assembly can control the rapid extension and retraction of the cutting blade to complete precise cutting at multiple angles and positions, solving the technical problems of existing equipment where the cutting method is singular and cannot cut irregular shapes; by using a flip-type closed cover to prevent multi-layer fabric from shifting, and by using an optical positioning probe with closed-loop feedback to achieve precise control of the cutting position, the technical problem of existing equipment where fabric shifting during multi-layer cutting leads to unstable accuracy is solved.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0025] like Figures 1-4 As shown, an adaptive pressure high-precision multi-layer cutting machine includes a main frame 100. The main frame 100 serves as the supporting skeleton of the equipment and is welded from high-strength metal profiles. An electrically controlled rotating guide frame 200 and an arc-shaped guide rail 220 matching the electrically controlled rotating guide frame 200 are movably mounted on its outer wall. The electrically controlled rotating guide frame 200 is movably mounted to the main frame 100 via an end mounting shaft 250. The electrically controlled rotating guide frame 200 uses the end mounting shaft 250 as its rotation fulcrum and can swing along the guide trajectory of the arc-shaped guide rail 220, achieving free adjustment of the guide angle.

[0026] The electrically controlled rotating guide frame 200 includes a tilting frame 210 and an angle-adjusting support rod 230. The tilting frame 210 is an integral frame structure with a guide sliding block 240 on the side facing the control surface. An arc-shaped guide rail 220 is fixedly installed on the outer wall of the main frame 100, and the guide sliding block 240 passes through the arc-shaped guide rail 220 and connects to the extended end of the angle-adjusting support rod 230. The angle-adjusting support rod 230 is movably installed on the back of the main frame 100 and uses an electric push rod or a lead screw mechanism driven by a servo motor. Through telescopic movement, it drives the guide sliding block 240 to slide along the arc-shaped guide rail 220, thereby driving the tilting frame 210 to swing around the end mounting shaft 250 as the fulcrum, realizing precise adjustment of the guide angle. The angle-adjusting support rod 230 is driven by a motor controller, and with the feedback signal from the optical positioning probe 600, closed-loop angle control can be achieved, with an angle adjustment accuracy of ±0.5 degrees.

[0027] An upper electrically controlled feeding wheel assembly 300 is provided at the upper opening of the flipping frame 210, and a lower electrically controlled discharging wheel assembly 400 is provided at the lower opening. The upper electrically controlled feeding wheel assembly 300 includes an upper assembly frame 310 fixed to both sides of the upper opening of the flipping frame 210 and an upper drive wheel 320 installed inside the upper assembly frame 310. The upper drive wheel 320 is driven by a servo motor and uses friction to evenly guide the multi-layer nonwoven fabric into the electrically controlled rotating guide frame 200. The lower electrically controlled discharging wheel assembly 400 includes a lower assembly frame 410 fixed to both sides of the lower opening of the flipping frame 210 and a lower drive wheel 420 installed inside the lower assembly frame 410. The lower drive wheel 420 is also driven by a servo motor and discharges the cut fabric from the electrically controlled rotating guide frame 200. The rotational speeds of the upper drive wheel 320 and the lower drive wheel 420 are uniformly coordinated and controlled by the controller to ensure that the fabric feed and discharge speeds are matched, thus preventing the fabric from accumulating or being stretched and deformed in the guide frame.

[0028] Symmetrical inner adjustment grooves 700 extending along the length direction are provided on the inner walls of both sides of the flip frame 210. The position-adjustable flip magnetic control cutting blade assembly 500 is slidably installed in the inner adjustment grooves 700 via sliding adjustment blocks 511 on both sides, and can freely slide and adjust the cutting position in the transverse direction inside the flip frame 210. The position-adjustable flip magnetic control cutting blade assembly 500 includes a sliding adjustment frame 510, an adjustment support rod 520 fixed to the outer surface of the flip frame 210, a flip control frame 530 hinged to the inner side of the sliding adjustment frame 510, a flip support rod 540 hinged to the outer side of the sliding adjustment frame 510, a telescopic control frame 550 slidably installed inside the flip control frame 530, a detachable cutting blade 560 installed on one side of the telescopic control frame 550, and an electromagnetic spring assembly 570.

[0029] The sliding adjustment frame 510 is an integral load-bearing frame with sliding adjustment blocks 511 on both sides that fit into the inner adjustment groove 700. The sliding adjustment frame 510 moves laterally along the inner adjustment groove 700 by adjusting the extension and retraction of the control rod 520, thus achieving lateral adjustment of the cutting position. The control rod 520 can be an electric push rod or a lead screw motor mechanism, automatically adjusted by the controller according to the cutting process parameters. The flip control frame 530 is hinged to the inside of the sliding adjustment frame 510, and the flip support rod 540 is hinged to the outside of the sliding adjustment frame 510. The extended end of the flip support rod 540 is movably connected to the side wall of the flip control frame 530. The flip support rod 540 drives the flip control frame 530 to rotate around the hinge point via electric extension and retraction, thereby adjusting the cutting angle so that the cutting blade 560 can cut into the fabric at any angle within the range of 0 to 90 degrees, adapting to the needs of straight cutting and irregular cutting.

[0030] The telescopic control frame 550 is slidably mounted inside the flip control frame 530. A detachable cutting blade 560 is mounted on one side of the telescopic control frame 550, and an electromagnetic spring assembly 570 is fixed inside the flip control frame 530. The electromagnetic spring assembly 570 includes an electromagnet 571 and an iron spring 572. The iron spring 572 is controlled by the magnetic force generated by the electromagnet 571. The telescopic control frame 550 is connected to the end of the iron spring 572 via a lateral control rod 551. When the electromagnet 571 is energized, it generates a magnetic force that attracts the iron spring 572, compressing it. This compresses the telescopic control frame 550 along the inside of the flip control frame 530 via the lateral control rod 551, causing the cutting blade 560 to extend quickly and perform the cutting action. When the electromagnet 571 is de-energized, the iron spring 572 returns to its elastic extension, pushing the telescopic control frame 550 back, and the cutting blade 560 retracts to a safe position. The current of the electromagnet 571 is precisely adjusted by the controller through a PWM pulse width modulation signal, so as to realize the real-time adjustable extension speed and cutting force of the cutting blade 560, ensuring the cutting quality of multi-layer fabrics of different thicknesses.

[0031] The optical positioning probe 600 is fixedly mounted on the side wall of the sliding adjustment frame 510 and moves together with the cutting blade assembly. The optical positioning probe 600 uses an industrial-grade laser displacement sensor or CCD image sensor to detect the offset of the cutting position relative to the fabric edge in real time and feeds the detection signal back to the controller. The controller calculates the actual position deviation of the cutting line based on the feedback data from the optical positioning probe 600, adjusts the lateral position of the cutting blade assembly by controlling the support rod 520, and adjusts the cutting angle by flipping the support rod 540, forming a closed-loop control circuit to ensure that the actual cutting line is at the same height as the preset cutting line, achieving a cutting positioning accuracy of ±0.1mm.

[0032] During use, the lateral spacing of the adjustable-position flip magnetic cutting blade assembly 500 within the flip frame 210 is pre-adjusted according to the required cutting method and length. When the upper-mounted electrically controlled feeding wheel assembly 300 introduces the nonwoven fabric, the optical positioning probe 600, in conjunction with the rotational speed of the upper-mounted drive wheel 320, detects the travel distance and edge position of the nonwoven fabric in real time. When the nonwoven fabric reaches the preset cutting position, the controller triggers the electromagnetic spring assembly 570 to drive the cutting blade 560 to quickly extend and perform cutting, achieving precise cutting during travel. By adjusting the swing angle of the electrically controlled rotating guide frame 200, horizontal or vertical cutting modes can be switched, allowing the equipment to flexibly adapt to the cutting needs of different process scenarios.

[0033] The flip frame 210 is also hinged to two sides with flip-type closing covers 800. During the cutting operation, the flip-type closing covers 800 flip downwards to cover the fabric, applying uniform pressure to the multiple layers of fabric and preventing the fabric from shifting or wrinkling during conveying and cutting. The flip-type closing covers 800 can be pneumatically or electrically driven, and their opening and closing actions are controlled by a controller.

[0034] The detachable cutting blade 560 is installed on one side of the telescopic control frame 550 using a standard universal interface. It can quickly change blades of different materials and tooth shapes according to the cutting materials and process requirements, adapting to the cutting needs of non-woven fabrics of different thicknesses and hardnesses.

[0035] The control system of this invention includes a main controller, employing a PLC or embedded controller, a motor driver, an electromagnet drive module, and a sensor interface module. The main controller controls the synchronous rotational speed of the upper drive wheel 320 and the lower drive wheel 420, the extension and retraction displacement of the angle adjustment strut 230, the lateral position of the strut 520, and the extension and retraction angle of the flip strut 540 via the motor driver; it controls the energizing current and PWM duty cycle of the electromagnet 571 via the electromagnet drive module; and it receives detection signals from the optical positioning probe 600 via the sensor interface module. The main controller has multiple pre-set cutting process parameter templates. Operators can select the corresponding cutting parameters for the nonwoven fabric type and specifications through the human-machine interface. The system automatically adjusts the action parameters of each actuator to achieve fully automated and intelligent cutting operations.
