Description

Technical Field

[0001] This invention relates to the field of thin film cutting technology, specifically to a thin film cutting device with a clamping component. Background Technology

[0002] In the field of film processing, cutting devices are widely used to cut continuous films to a fixed length. However, existing equipment often suffers from problems such as unstable film positioning, large tension fluctuations, and poor coordination between clamping and film pulling during the cutting process. These problems can easily lead to uneven cuts, film offset, or breakage, affecting cutting quality and production efficiency. Therefore, a film cutting device with clamping components is needed to achieve automatic clamping, quantitative film pulling, and stable tensioning before cutting, thereby improving cutting accuracy and operational reliability.

[0003] Patent CN212169352U discloses a film cutting device with clamping components, which relates to the field of film processing equipment. It includes a worktable, a conveyor belt, and an extension table. A cutting component is placed on the extension table. The cutting component includes a support column, a moving platform, a mounting frame, a laser cutting head, a laser dust cover, and an infrared sensing device. A second pressing component and a first pressing component are respectively provided on the left and right sides of the worktable. This invention utilizes a conveyor belt on a workbench to transport the film, a cutting component placed on a receiving platform of an extension table for cutting, an infrared sensing device and a laser cutting head for cutting the film, and pressing components on both sides to press the film together, thereby increasing the effectiveness of film positioning and cutting. In addition, a laser dust cover is provided around the laser cutting head to prevent dust from accumulating when not in use. A counterweight is installed at the rear of the moving platform to prevent it from tipping over, increasing the overall balance of the cutting process. However, this patent still has the problem that the cut edges of the film are prone to loosening, curling or curling after cutting, which affects the cutting effect.

[0016] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

In addition, the retraction action of the lower cutting plate is linked to the pressure roller to automatically press the film, without the need for an additional power source.

[0018] This film cutting device with clamping components drives the film pressing frame to rotate via a hydraulic rod retraction linkage push rod and a flip plate. It achieves automatic film tensioning before cutting without an additional power source. The device has a compact structure and strong synchronous operation. The pressure rod, in conjunction with the internal pressure spring, can elastically adjust the downward pressure, ensuring stable film tension while preventing the film from breaking due to excessive tension. This improves the safety of the cutting process and its adaptability to films of different thicknesses. Simultaneously, as the film pressing frame moves, it pushes the deflection groove rod, which, through its internal compression spring, drives the brake plate and friction arc block to abut against the film winding shaft. This generates controllable frictional resistance to prevent the film winding shaft from continuing to unwind during cutting. This, combined with the clamping action of the film pressing frame, forms a two-way tensioning cooperation, effectively preventing the film from loosening, shifting, or wrinkling in the cutting area, ensuring neat cutting edges, and improving cutting accuracy and reliability.

[0019] This film cutting device with clamping components utilizes the release slot and clamping slot on the slide plate in conjunction with the front spring plate to achieve automatic clamping and release. It eliminates the need for additional pneumatic or electric control components, simplifying the control logic and reducing costs. At the same time, when the connecting rod slides back from the clamping slot to the release slot, it automatically releases the cut film, ensuring that the film cross-section falls neatly on the top surface of the support frame at the same position, facilitating collection or processing in the next process. The clamping block automatically resets by pressing the rear spring plate through the connecting rod, realizing a fully automatic cycle of clamping, film pulling, release, and reset, which improves cutting efficiency, positioning accuracy, and operational reliability.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-9 An embodiment of the present invention is as follows: a film cutting device with clamping components, including a support frame 1, a cutting side plate 2, a sliding groove side plate 3, a guide shaft side plate 4, and a film 8. A cutting mechanism 5 for cutting the film 8 into equal sizes is provided above the support frame 1.

[0032] A guide mechanism 6 is provided in front of the cutting mechanism 5 to guide the film 8 to be conveyed and to assist in its tensioning;

[0033] A clamping mechanism 7 is provided behind the cutting mechanism 5 to neatly arrange the cut film 8;

[0034] The cutting mechanism 5 includes a mounting plate 501. A hydraulic rod 502 is mounted in the middle of the mounting plate 501. A push plate 503 is mounted at the end of the hydraulic rod 502 away from the mounting plate 501. Hinge plates 504 are fixedly connected to both sides of the push plate 503. An upper hinge rod 505 and a lower hinge rod 506 are hinged to the side of each hinge plate 504. An upper cutting plate 507 is slidably connected to the side of the upper hinge rod 505. A lower cutting plate 508 is slidably connected to the side of the lower hinge rod 506. A side groove support column 509 is fixedly connected to the front side of the mounting plate 501. A cutter 510 is mounted on the top of both the lower cutting plate 508 and the upper cutting plate 507.

[0035] The cutting mechanism 5 also includes a cutting panel 511. Two vertical slide rods 512 are fixedly connected to the top surface of the cutting panel 511. A lifting end 513 is slidably connected to the outside of the vertical slide rods 512. A lower pressure plate 514 is fixedly connected to the bottom of the lifting end 513. Two spring rods 516 are slidably connected to the surface of the lower pressure plate 514. A pressure roller 515 is installed at the bottom end of the spring rods 516. Side guide blocks 517 are slidably connected to both sides of the cutter 510.

[0036] The side groove support column 509 is fixedly connected to the support frame 1. Vertical grooves are provided on both sides of the side groove support column 509, and these vertical grooves are slidably connected to the ends of the upper hinge rod 505 and the lower hinge rod 506, respectively. The cutting panel 511 is fixedly connected to the top of the side groove support column 509. A reciprocating spring is provided on the outer side of the spring rod 516, and both ends of the reciprocating spring are fixedly connected to the top of the lower pressure plate 514 and the pressure roller 515, respectively. When the film 8 needs to be cut after passing through the cutting panel 511, the hydraulic rod 502 retracts and pulls the connected push plate 503 towards the mounting plate 501. The push plate 503... The movable hinge plates 504 on both sides move, causing the hinge plates 504 to push the connected upper hinge 505 and lower hinge 506 to move synchronously. The upper hinge 505 and lower hinge 506, pushed by the hinge plates 504, slide along the vertical groove on the side of the side support column 509. The upper hinge 505 deflects, causing the upper cutting plate 507 to slide along the sliding groove on the side of the upper hinge 505. This causes the connection between the upper cutting plate 507 and the upper hinge 505 to be subjected to force and move downward. The upper cutting plate 507 drives the cutter 510 connected at this point to move downward. Similarly, the lower hinge 506 deflects upward along the vertical groove on the side of the side support column 509. The lower cutting plate 508 is lifted upwards via the side groove of the lower hinge rod 506, bringing the cutter 510 connected to the lower cutting plate 508 closer to the upper cutting plate 507. The upper and lower cutters 510 are staggered to cut the passing film 8. In addition, when the lower cutting plate 508 moves downwards after cutting, the lower cutting plate 508 drives the lifting end 513 to move along the vertical slide rod 512 to push the connected lower pressure plate 514. The lower pressure plate 514, through the connected spring rod 516, brings the pressure roller 515 closer to the top of the film 8, and cooperates with the cutting panel 511 to press and position the cut edge of the film 8. To prevent detachment, the compact structure and smooth transmission ensure uniform force and neat cuts when the upper and lower blades 510 are staggered during cutting, reducing the stretching and deformation of the film 8. In addition, the retraction action of the lower cutting plate 508 is linked to the pressure roller 515 to automatically press the film 8 without the need for an additional power source. The spring rod 516 provides elastic pressing force to adapt to films 8 of different thicknesses and avoid damage. The vertical slide rod 512 ensures the vertical stability of the lifting end 513, thereby effectively positioning the film 8 at the moment of cutting and afterward, preventing cutting errors caused by edge lifting or offset, and improving cutting quality and continuity.

[0037] The guiding mechanism 6 includes a push rod 601, a flip plate 602 is slidably connected to the front end of the push rod 601, a pressure plate 603 is fixedly connected to the end of the flip plate 602 away from the push rod 601, a pneumatic rod 604 is hinged to the inner side of the pressure plate 603, and an adaptive pressure rod 605 is slidably connected to the inner side of the pressure plate 603.

[0038] The guiding mechanism 6 also includes a deflection groove rod 606. A brake pad 607 is slidably connected to one end of the deflection groove rod 606 away from the film pressing frame 603. A friction arc block 608 is fixedly connected to the side of the brake pad 607. A support shaft block 612 is fixedly connected to the top front side of the support frame 1. A film winding shaft rod 609 is rotatably connected above the support shaft block 612. A central shaft roller 610 is rotatably connected to the side of the guide shaft side plate 4. A top shaft roller 611 is provided on the front side of the cutting panel 511.

[0039] The pressure film frame 603 is rotatably connected to the support frame 1. The end of the pneumatic rod 604 away from the pressure film frame 603 is rotatably connected to the support frame 1. An internal pressure spring is provided at the end of the adapting pressure rod 605, and the two ends of the internal pressure spring are fixedly connected to the side wall of the pressure film frame 603 and the surface of the adapting pressure rod 605, respectively. The deflection groove rod 606 is rotatably connected to the guide shaft side plate 4. The brake pad 607 is rotatably connected to the shaft support block 612. A compression spring is provided on the side of the deflection groove rod 606, and the two ends of the compression spring are fixedly connected to the brake pad 607 and the deflection groove rod 606, respectively. When cutting is required, the hydraulic rod 502 is in a retracted state, pulling the push plate 503 to move. 503 pushes the connected push rod 601, causing the flip plate 602 to be stressed and driving the film pressing frame 603 to move. The film pressing frame 603 rotates with the flip plate 602 around the connection point relative to the support frame 1. After rotation, the adapting pressure rod 605 connected to the film pressing frame 603 moves downward to apply pressure to the bypassed film 8, so that the film 8 in the cutting state is in a taut state. After the film pressing frame 603 deflects, the adapting pressure rod 605 squeezes the internal pressure spring to adjust the position of the adapting pressure rod 605. By adjusting the position, the adapting pressure rod 605 adapts to the tension of the film 8, preventing the film 8 from breaking. At the same time, during the movement of the film pressing frame 603, it contacts and pushes the deflection groove rod 606. At one end, the deflection groove rod 606 is deflected around the connection of the guide shaft side plate 4 under force, and the brake pad 607 is pushed around the connection of the support block 612 by the compression spring inside the deflection groove rod 606. This causes the friction arc block 608 connected to the brake pad 607 to approach the film winding shaft rod 609, so that the film winding shaft rod 609 prevents rotation through friction and works with the film pressing frame 603 to tension the film 8. The hydraulic rod 502 retracts the linkage push rod 601 and the flipping plate 602 to drive the film pressing frame 603 to rotate. Automatic film pressing and tensioning before cutting can be achieved without an additional power source. The structure is compact and the action is highly synchronized. The pressure rod 605 can be elastically adjusted with the internal pressure spring. Adjusting the downward pressure ensures stable tension of the film 8 while preventing it from breaking due to excessive tension, thus improving the safety of the cutting process and adaptability to films of different thicknesses. Simultaneously, when the pressure frame 603 moves, it pushes the deflection groove rod 606, which, through its internal compression spring, drives the brake plate 607 and friction arc block 608 to abut against the film winding shaft 609, generating controllable frictional resistance to prevent the film winding shaft 609 from continuing to unwind during cutting. This, combined with the pressing action of the pressure frame 603, forms a bidirectional tensioning cooperation, effectively preventing the film 8 from becoming loose, shifted, or wrinkled in the cutting area, ensuring neat cutting edges, and improving cutting accuracy and reliability.

[0040] The clamping mechanism 7 includes a threaded rod 701. Each threaded rod 701 is rotatably connected to a shaft seat 702 at both ends. A motor seat 703 is fixedly connected to the rear side of the rear shaft seat 702. A sliding seat 704 is threadedly connected to the outer side of the threaded rod 701. A bracket 705 is fixedly connected above the sliding seat 704. Three clamping blocks 706 are fixedly connected to the front side of the bracket 705. A fixing block 707 is fixedly connected to the bottom surface of each clamping block 706. A clamping block 708 is slidably connected to the top of the clamping block 706. A connecting rod 709 is fixedly connected to the side of the clamping block 708. A sliding plate 710 is fixedly connected to the side of the sliding plate 3. A clamping groove 711 and a releasing groove 712 are provided on the side of the sliding plate 710. A spring plate 713 is installed on the inner wall of the connection between the clamping groove 711 and the releasing groove 712.

[0041] The motor base 703 is fixedly connected to the slide side plate 3. The clamping groove 711 and the releasing groove 712 are connected. The connecting rod 709 is slidably connected to the clamping groove 711 and the releasing groove 712. A groove is provided on the rear surface of the cutting panel 511. One end of the spring plate 713 is fixedly connected to the inner wall of the clamping groove 711 or the releasing groove 712. Before cutting, the motor drives the threaded rod 701 to rotate through the motor base 703, so that the threaded rod 701 drives the sliding seat 704 to move from back to front. The clamping block 708 moves together with the sliding seat 704 and moves along the slide plate 710 through the connecting rod 709. When the connecting rod 709 slides along the release groove 712, there is a gap between the clamping block 708 and the fixing block 707. When the connecting rod 709 passes the spring plate 713 at the front end of the release groove 712, the spring plate 713 is compressed and deformed, allowing the connecting rod 709 to pass through and enter the clamping groove 711. At this time, the connecting rod 709 drives the clamping block 708 and the clamping block 706 to slide close to the fixing block 707 and clamp the edge of the film 8 at the groove of the cutting panel 511. Subsequently, the threaded rod 701 reverses, so that the clamping block 708 in the clamping state moves from front to back along with the sliding seat 704. The film 8 is then pulled by the clamping block 708, and the film 8 outside the film winding shaft 609 is unfolded. One end of the cut film 8 is clamped by the clamping block 708, and the other end falls to the top surface of the support frame 1. As the clamping block 708 continues to move from back to front, when the connecting rod 709 connected to the clamping block 708 slides from the clamping groove 711 into the release groove 712, the clamping block 708 no longer clamps the cut film 8, allowing the film 8 to fall to the same position. Then, the clamping block 708 is reset by pressing the rear spring plate 713 through the connecting rod 709. The release groove 712 on the slide plate 710 and the clamping block are used to reset the film 8. The slot 711, in conjunction with the front spring plate 713, enables automatic clamping and release, eliminating the need for additional pneumatic or electric control components. This simplifies the control logic and reduces costs. Simultaneously, when the connecting rod 709 slides from the clamping slot 711 back to the releasing slot 712, the cut film 8 is automatically released, ensuring that the cut surface of the film 8 falls neatly at the same position on the top surface of the support frame 1 for easy collection or processing in the next process. Meanwhile, the clamping block 708 automatically resets by pressing the rear spring plate 713 through the connecting rod 709. This achieves a fully automatic cycle of clamping, pulling, releasing, and resetting, improving cutting efficiency, positioning accuracy, and operational reliability.

[0042] Working principle: When the film 8 needs to be cut by the cutting panel 511, the hydraulic rod 502 retracts and pulls the connected push plate 503 closer to the mounting plate 501. The push plate 503 drives the connected hinge plates 504 on both sides to move, so that the hinge plates 504 push the connected upper hinge 505 and lower hinge 506 to move synchronously. The upper hinge 505 and lower hinge 506 pushed by the hinge plates 504 slide along the vertical groove on the side of the side groove support column 509. The upper hinge 505 deflects and drives the upper cutting plate 507 to slide along the sliding groove on the side of the upper hinge 505, so that the connection between the upper cutting plate 507 and the upper hinge 505 is subjected to force and moves downward. The upper cutting plate 507 drives the cutter 510 connected at that point to move downward. Similarly, the lower hinge rod 506 deflects upward along the vertical groove on the side of the side support column 509, and lifts the lower cutting plate 508 upward through the side groove of the lower hinge rod 506, so that the cutter 510 connected to the lower cutting plate 508 is close to the upper cutting plate 507. The upper and lower cutters 510 are staggered to cut the film 8. In addition, when the lower cutting plate 508 moves downward after cutting, the lower cutting plate 508 drives the lifting end 513 to move along the vertical slide rod 512 to push the connected lower pressure plate 514. The lower pressure plate 514, through the connected spring rod 516, brings the pressure roller 515 close to the top of the film 8, and cooperates with the cutting plate 511 to press and position the cut edge of the film 8 to prevent it from falling off.

[0043] When cutting is required, the hydraulic rod 502 is in a retracted state, pulling the push plate 503 to move. The push plate 503 pushes the connected push rod 601, causing the flip plate 602 to be stressed and driving the film pressing frame 603 to move. The film pressing frame 603 rotates with the flip plate 602 around the connection point relative to the support frame 1. After rotation, the adapting pressure rod 605 connected to the film pressing frame 603 moves downward to apply pressure to the bypassed film 8, keeping the film 8 in a taut state during cutting. After the film pressing frame 603 deflects, the adapting pressure rod 605 compresses the internal pressure spring to adjust the position of the adapting pressure rod 605. By adjusting the position, the pressure rod 605 adapts to the tension of the film 8, preventing the film 8 from breaking. At the same time, during the movement of the film pressing frame 603, it contacts and pushes one end of the deflection groove rod 606. One end of the deflection groove rod 606 is deflected around the connection of the guide shaft side plate 4 under force, and the compression spring inside the deflection groove rod 606 pushes the brake pad 607 to deflect around the connection of the support shaft block 612, so that the friction arc block 608 connected to the brake pad 607 approaches the film winding shaft rod 609, so that the film winding shaft rod 609 prevents rotation through friction and works with the film pressing frame 603 to tighten the film 8.

[0044] Before cutting, the motor drives the threaded rod 701 to rotate at the motor base 703, causing the threaded rod 701 to move the sliding seat 704 from back to front. The clamping block 708 moves together with the sliding seat 704 and slides along the side of the slide plate 710 via the connecting groove rod 709. When the connecting groove rod 709 slides along the release groove 712, there is a gap between the clamping block 708 and the fixed block 707. When the connecting groove rod 709 passes the spring plate 713 at the front end of the release groove 712, the spring plate 713 is compressed and deformed, allowing the connecting groove rod 709 to pass through and enter the clamping groove 711. At this time, the connecting groove rod 709 drives the clamping block 708 and the clamping block 706 to slide closer to the fixed block 707, cutting the cutting panel 51. The edge of the film 8 at the groove is clamped. Then, the threaded rod 701 reverses, causing the clamping block 708, which is in the clamping state, to move from front to back along with the sliding seat 704. Then, the clamping block 708 pulls the film 8, and the film 8 outside the film winding shaft 609 is unfolded. One end of the cut film 8 is clamped by the clamping block 708, and the other side of the cut falls to the top surface of the support frame 1. As the clamping block 708 continues to move from back to front, when the connecting groove rod 709 connected to the clamping block 708 slides from the clamping groove 711 into the release groove 712, the clamping block 708 no longer clamps the cut film 8. After the film 8 falls to the same position, the clamping block 708 resets by pressing the rear spring plate 713 through the connecting groove rod 709.
