Description

Technical Field

[0001] This utility model belongs to the field of thin film production technology, specifically relating to a high-strength cross-film stretching device. Background Technology

[0002] In the stretching process of high-strength cross-linked membranes, the uneven distribution of internal stress is a crucial and complex issue. These internal stresses arise from the combined effects of various factors, including differences in the microstructure of the material, temperature gradients during processing, variations in stretching rate, and limitations in equipment precision. They form a complex stress field within the membrane material.

[0003] Uneven internal stress can also lead to uneven membrane stretching. To address this issue, optimizing the temperature control system is crucial. A temperature control system can precisely control the heating temperature of the membrane during stretching, ensuring uniform heating. By avoiding stress concentration caused by excessively high or low temperatures, the temperature control system can significantly reduce the unevenness of internal stress, thereby reducing problems such as deformation, breakage, and uneven stretching during membrane stretching. Therefore, this invention proposes a high-strength cross-membrane stretching device to solve the problems of uneven stretching and heating during stretching. Summary of the Invention

[0004] The purpose of this invention is to provide a high-strength cross-film stretching device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-strength cross-film stretching device, characterized in that: the high-strength cross-film stretching device has a first protective plate and a second protective plate, the first protective plate and the second protective plate are connected by a leveling roller and a first tension roller, both the first protective plate and the second protective plate are provided with a stretching component on the side away from the first tension roller, a bending roller is provided above the first tension roller, a motor is fixedly installed on the side of the first protective plate away from the bending roller, and a heating component is provided on the side of the second protective plate away from the bending roller. A straight roller is positioned below the curved roller. The stretching assembly includes a telescopic cylinder, a rotating circular plate, a first support plate, a second support plate, a movable plate, a sliding groove, and a sliding rod. Both the first and second protective plates are fixedly fitted with the first support plate, the second support plate, and the telescopic cylinder. A sliding rod is fixedly mounted on the first support plate, and a rotating circular plate is inserted through the second support plate. The output end of the telescopic cylinder is connected to the rotating circular plate. A movable plate is fixedly mounted on the rotating circular plate, and a sliding groove is formed at the end of the movable plate near the first support rod. The sliding rod passes through the sliding groove. During production, the high-strength cross-film is pulled by the operator, passing sequentially under the leveling roller and the first tension roller, around the tension control roller and the curved roller, and finally exiting through the straight roller. The stretching assembly adjusts the position of the tension control roller according to the state of the cross-film, allowing for real-time tension adjustment based on production conditions. A heating assembly provides uniform heating to the cross-film, preventing uneven stress.

[0006] As a preferred technical solution, the two moving plates are connected by a tension control roller.

[0007] As a preferred technical solution, the high-strength cross-film passes sequentially through a leveling roller, a first tension roller, and a tension control roller to a bending roller, and is finally pulled out by a straight roller.

[0008] As a preferred technical solution, the heating assembly includes a rotating plate, a rotating rod one, a swing rod, a moving rod, a rotating rod two, a rotating rod three, a U-shaped extrusion plate, a fixed plate one, a fixed plate two, a pull rod one, a pull rod two, a heating tube, an extrusion block, and a through hole; a heating tube is provided below the bending roller, a rotating plate is fixedly installed at the output end of the bending roller, a rotating rod one is fixedly installed on the rotating plate, a swing rod is inserted on the rotating rod one, a rotating rod two and a rotating rod three are respectively installed at both ends of the swing rod, a fixed seat is fixedly installed below the rotating plate, a fixed rod is installed on the fixed seat, the fixed rod is connected to the rotating rod two through a moving rod, a U-shaped extrusion seat is installed below the swing rod, a U-shaped extrusion plate and an extrusion block are slidably installed in the U-shaped extrusion seat, a fixed plate one and a fixed plate two are fixedly installed on the U-shaped extrusion plate, a through hole is opened on the U-shaped extrusion plate, the rotating rod three is connected to the fixed plate one and the fixed plate two through a pull rod one, and the rotating rod one is connected to the extrusion block through a pull rod two. When the high-strength cross-cut film passes through the curved roller and the straight roller, the motor drives the curved roller to rotate, which in turn drives the rotating plate to rotate. The rotating plate drives the swing rod to move through the rotating rod one, and the rotating rod one drives the pull rod two to pull the extrusion block to slide in the U-shaped extrusion seat. At the same time, the rotating rod two drives the pull rod two to pull the U-shaped extrusion plate to slide in the U-shaped extrusion seat. Due to the time difference between the movement of the pull rod one and the pull rod two, when the pull rod one moves upward, the pull rod two moves downward, which causes the extrusion block and the U-shaped extrusion plate to move alternately, thereby extruding the air bag. The hot gas in the air bag is continuously sprayed onto the surface of the high-strength cross-cut film through the small holes on the heating tube, avoiding uneven local heating.

[0009] As a preferred technical solution, the extrusion block and the U-shaped extrusion plate are connected to the U-shaped extrusion seat through an air bladder, the second pull rod is inserted through a through hole, and the motor output end is connected to the bending roller input end.

[0010] As a preferred technical solution, the heating tube has several small holes, the input end of the heating tube is connected to the airbag, and the input end of the airbag is connected to an air heating box.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: It is equipped with a stretching component and a heating component. The rotation of the rotating disc is adjusted by the telescopic cylinder, thereby controlling the tilt angle of the moving plate to change the position of the tension control roller and thus changing the tension of the strong cross film. At the same time, the rotation of the bending roller drives the swing rod to move, and the extrusion block and U-shaped extrusion plate alternately extrude the air bag through the first and second pull rods. This allows the hot gas to be evenly sprayed onto the surface of the strong cross film through the heating pipe, avoiding uneven local heating and improving product quality.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-4 As shown, an embodiment of this utility model provides a high-strength cross-film stretching device. As... Figures 1-3 As shown, the high-strength cross-film stretching device includes a protective plate 1 and a protective plate 2. The protective plate 1 and the protective plate 2 are connected by a leveling roller 3 and a first tension roller 4. A stretching assembly 5 is provided on the side of the protective plate 1 and the protective plate 2 facing away from the first tension roller 4. A bending roller 8 is provided above the first tension roller 4. A motor 6 is provided at the input end of the bending roller 8, and a heating assembly 7 is provided at the output end of the bending roller 8. A straight roller 9 is provided below the bending roller 8. The stretching assembly 5 includes a telescopic cylinder 501, a rotating circular plate 502, a first support plate 503, a second support plate 504, and a movable... The protective plate 1 and the protective plate 2 are each fixedly mounted with a support plate 1 503, a support plate 2 504, and a telescopic cylinder 501. The support plate 1 503 is fixedly mounted with a slide rod 507. The support plate 2 504 is inserted with a rotating circular plate 502. The output end of the telescopic cylinder 501 is connected to the rotating circular plate 502. The rotating circular plate 502 is fixedly mounted with a movable plate 505. The movable plate 505 has a sliding groove 506 at one end near the support rod 1. The slide rod 507 passes through the sliding groove 506. During production, the high-strength cross-film is pulled by the operator through the leveling roller 3 and the first tension roller 4, then around the tension control roller 10 and the bending roller 8, and finally exited by the straight roller 9. The tensioning component 5 adjusts the position of the tension control roller 10 according to the state of the cross-film. When the tension of the high-strength cross-film needs to be adjusted, the telescopic cylinder 501 is activated. The extension or shortening of the output end of the telescopic cylinder 501 drives the rotating disc 502 to rotate, thereby adjusting the tilt angle of the moving plate 505. At the same time, the slide rod 507 slides in the sliding groove 506 to further fix the tilt angle of the moving plate 505. By adjusting the tilt angle, the height of the tension control roller 10 can be changed. The tension can be adjusted in real time according to the production situation. The heating component 7 heats the cross-film evenly to avoid uneven stress.

[0024] like Figure 3 As shown, the two moving plates 505 are connected by a tension control roller 10.

[0025] like Figure 1As shown, the high-strength cross-film passes sequentially through the leveling roller 3, the first tension roller 4, and the tension control roller 10 to the bending roller 8, and is finally pulled out by the straight roller 9.

[0026] like Figures 3-8 As shown, the heating assembly 7 includes a rotating plate 701, a rotating rod 702, a swing rod 703, a moving rod 704, a rotating rod 705, a rotating rod 706, a U-shaped extrusion plate 707, a fixed plate 708, a fixed plate 709, a pull rod 710, a pull rod 711, a heating tube 712, an extrusion block 713, and a through hole 714; a heating tube 712 is provided below the bending roller 8, and a rotating plate 701 is fixedly installed at the output end of the bending roller 8. A rotating rod 702 is installed on the rotating plate 701, and a swing rod 703 is inserted through the rotating rod 702. A rotating rod 705 and a rotating rod 706 are respectively installed at both ends of the swing rod 703. A fixed base 11 is fixedly installed below the rotating plate 701. A fixed rod 12 is installed on the fixed base 11. The fixed rod 12 is connected to the rotating rod 705 via a moving rod 704. A U-shaped extrusion seat is installed below the swing rod 703. A U-shaped extrusion plate 707 and an extrusion block 713 are slidably installed inside the U-shaped extrusion seat. A fixed plate 708 and a fixed plate 709 are fixedly installed on the U-shaped extrusion plate 707. A through hole 714 is opened on the U-shaped extrusion plate 707. The rotating rod 706 is connected to the fixed plate 708 and the fixed plate 709 via a pull rod 710. The rotating rod 702 is connected to the extrusion block 713 via a pull rod 711. When the high-strength cross-laminated film passes through the leveling roller 3, the first tension roller 4, and the stretching assembly 5, the motor 6 drives the bending roller 8 to rotate, which in turn drives the rotating plate 701 to rotate. The rotating plate 701 drives the swing rod 703 to move through the rotating rod 702. The rotating rod 702 drives the pull rod 711 to pull the extrusion block 713 to slide in the U-shaped extrusion seat. At the same time, the rotating rod 706 drives the pull rod 710 to pull the U-shaped extrusion plate 707 to slide in the U-shaped extrusion seat. Since there is a time difference between the movement of the pull rod 710 and the pull rod 711, when the pull rod 710 moves upward, the pull rod 711 moves downward, which causes the extrusion block 713 and the U-shaped extrusion plate 707 to move alternately, thereby extruding the airbag. The hot gas in the airbag is continuously sprayed onto the surface of the high-strength cross-laminated film through the small holes on the heating tube 712, avoiding uneven local heating.

[0027] like Figure 8 As shown, the extrusion block 713 and the U-shaped extrusion plate 707 are connected to the U-shaped extrusion seat through an air bladder, the second pull rod 711 passes through the through hole 714, and the output end of the motor 6 is connected to the input end of the bending roller 8.

[0028] The working principle of this utility model is as follows: During production, the high-strength cross-film is pulled by the operator through the leveling roller 3 and the first tension roller 4, passing under the tension control roller 10 and the bending roller 8, and finally exiting through the straight roller 9. The tensioning component 5 adjusts the position of the tension control roller 10 according to the state of the cross-film. When it is necessary to adjust the tension of the high-strength cross-film, the telescopic cylinder 501 is activated. The extension or shortening of the output end of the telescopic cylinder 501 drives the rotating circular plate 502 to rotate, thereby adjusting the tilt angle of the moving plate 505. At the same time, the slide rod 507 slides in the sliding groove 506 to further fix the tilt angle of the moving plate 505. By adjusting the tilt angle, the height of the tension control roller 10 can be changed. The tension can be adjusted in real time according to the production situation. The heating component 7 heats the cross-film evenly to avoid uneven stress.

[0029] After the high-strength cross-laminated film passes through the stretching assembly 5, the motor 6 drives the bending roller 8 to rotate, which in turn drives the rotating plate 701 to rotate. The rotating plate 701 drives the swing rod 703 to move through the rotating rod 702. The rotating rod 702 drives the pull rod 711 to pull the extrusion block 713 to slide in the U-shaped extrusion seat. At the same time, the rotating rod 706 drives the pull rod 710 to pull the U-shaped extrusion plate 707 to slide in the U-shaped extrusion seat. Since there is a time difference between the movement of the pull rod 710 and the pull rod 711, when the pull rod 710 moves upward, the pull rod 711 moves downward, which causes the extrusion block 713 and the U-shaped extrusion plate 707 to move alternately, thereby extruding the airbag. The hot gas in the airbag is continuously sprayed onto the surface of the high-strength cross-laminated film through the small holes on the heating tube 712, avoiding uneven local heating.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
