Technical Field
[0001] This utility model belongs to the technical field of adjustment devices, specifically a winding tension adjustment device for roll materials. Background Technology
[0002] Waterproof membrane is the first line of defense in waterproofing projects. During its production, it often needs to be wound up by a winding device. During the winding process, the tension of the waterproof membrane can be effectively changed by the tension adjustment device.
[0003] Current tension adjustment devices typically consist of a fixed base, an adjustment frame fixedly connected to the top of the base, a cylinder fixedly connected to the top of the adjustment frame, a fixed frame fixedly connected to the bottom of the cylinder output end, and an adjustment roller rotatably connected to the inner wall of the fixed frame. The material to be wound first passes through the unwinding roller rotatably connected to the unwinding frame, which is also fixedly connected to the top of the base, and then passes between the adjustment roller and the fixed frame. It is then wound onto the take-up roller mounted on the take-up frame, which is also fixedly connected to the top of the base. The motor on the take-up frame is activated to rotate the take-up roller, and the cylinder is activated to raise and lower the adjustment frame, pulling up the portion of the material located within the fixed frame. This ensures that when one end of the material is fixed by the take-up frame and the other end by the take-up roller, the middle portion is tightened as the fixed frame rises, thus keeping the material wound on the take-up frame in a taut state.
[0004] When adjusting the tension of rolls of material with different widths, the lengths of the take-up roller, unwind roller, and adjusting roller are usually set to their maximum lengths in advance to ensure tension adjustment and winding. However, this can easily cause the roll to slip during winding, affecting the winding and tension adjustment effect. Installing movable limiting rings on the adjusting roller and unwind roller requires readjusting the limiting rings on the adjusting roller and unwind roller simultaneously when changing to different widths of fabric. This operation is cumbersome and costly. Therefore, a roll winding tension adjustment device is proposed to address the above problems. Utility Model Content

[0024] 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.
[0025] Specific implementation examples are given below.
[0026] Please see Figures 1-4 This utility model provides a roll material winding tension adjustment device, including a base 1; a winding frame 2 is fixedly connected to the top of the base 1, a winding roller is installed inside the winding frame 2, the winding roller is detachably installed on the winding reel rotatably connected to the inner wall of the winding frame 2 by bolts, and the winding reel is driven to rotate by a motor fixedly connected to one side of the winding frame 2, so that the winding roller can be replaced by removing and installing bolts after the roll material is wound up; an adjustment frame 3 is fixedly connected to the top of the base 1, a guide frame 4 is fixedly connected to the top of the base 1, a guide roller 5 is rotatably connected to the inner wall of the guide frame 4 by a rotating shaft, and a guide ring 6 is slidably connected to the outer wall of the guide roller 5; before adjusting the tension of the roll material winding, the roll material can be passed through the two guide rollers 5 and the adjustment roller and the first double-headed threaded rod 73 in sequence and one end is wound around the winding roller to adjust the tension.
[0027] An adjustment mechanism 7 is provided on the adjustment frame 3. The adjustment mechanism 7 includes a cylinder 71 fixedly connected to the top of the adjustment frame 3. The output end of the cylinder 71 passes through the adjustment frame 3 and is fixedly connected to a lifting frame 72. A first double-ended threaded rod 73 is rotatably connected to the inner wall of the lifting frame 72. Both ends of the outer wall of the first double-ended threaded rod 73 are threadedly connected to transmission blocks 74. A transmission plate 75 is slidably connected inside the lifting frame 72. A positioning groove is opened on the top of the transmission plate 75. A positioning block 76 is slidably connected in the positioning groove. One end of the positioning block 76 extends out of the positioning groove. The slot is fixedly connected to the transmission block 74. A connecting plate 77 is fixedly connected to one side of the transmission plate 75, and the other end of the connecting plate 77 is fixedly connected to the guide ring 6. An adjusting roller is rotatably connected to the inner wall of the adjusting frame 3. A positioning rod 8 is fixedly connected to one side of the inner wall of the lifting frame 72. One end of the positioning rod 8 passes through the transmission plate 75 and is fixedly connected to the other side of the inner wall of the lifting frame 72. During operation, the adjusting mechanism 7 can be used to quickly and synchronously adjust the upper limit of the winding roller and the guide roller 5 according to the required width of the roll material. The adjustment of the positioning components simplifies the operation steps and ensures the synchronization and accuracy of the adjustment. Specifically, based on the length of the roll to be wound, manually rotating the first double-ended threaded rod 73 drives the two transmission blocks 74 on it to move the two positioning blocks 76 away from or towards each other. The transmission plate 75, through the connecting plate 77, drives the two guide rings 6 sliding on the outer wall of the guide roller 5 to move, thus synchronously completing the adjustment of the roll's positioning on the guide roller 5 and the adjusting roller. After the roll is passed sequentially through the guide roller 5 and the adjusting roller and one end is wound onto the take-up roller, the pneumatic system can be started. The cylinder 71 drives the lifting frame 72 to rise, pulling up the portion of the roll material located between the adjusting roller and the first double-headed threaded rod 73, causing the roll material to gradually tighten. The positioning block 76 and the positioning groove are both T-shaped, which ensures that the positioning block 76 does not interfere with the movement of the transmission plate 75 when it moves with the transmission block 74. That is, when the lifting frame 72 drives the positioning block 76 to rise and fall through the transmission block 74, the positioning block 76 also slides in the positioning groove. The positioning rod 8 facilitates the movement of the auxiliary transmission plate 75 and the positioning of the auxiliary plate.
[0028] Furthermore, such as Figure 1 and Figure 4As shown, a cleaning frame 9 is fixedly connected to the top of the base 1. A cleaning groove is provided on the inner side wall of the cleaning frame 9. A second double-headed threaded rod 10 is rotatably connected to the inner bottom wall of the cleaning groove. Both ends of the outer wall of the second double-headed threaded rod 10 are threadedly connected to cleaning plates 11. There are two sets of cleaning plates 11. A cleaning cloth 12 is attached to the opposite side of the two sets of cleaning plates 11 by Velcro. Both sides of the cleaning plates 11 are arc-shaped. The top of the double-headed threaded rod passes through the cleaning frame 9 and is fixedly connected to a knob 13. During operation, the arc shape on both sides of the cleaning plate 11 reduces wear on the roll material. The second double-headed threaded rod 10 and the cleaning plate 11 facilitate the removal of dust adhering to the roll material. Before the roll material passes through the adjusting frame 3 and is wound onto the take-up roller, the roll material is first passed between the two cleaning plates 11 and then wound onto the take-up roller. By rotating the knob 13, the second double-headed threaded rod 10 is rotated, causing the two cleaning plates 11 to move closer to each other and adhere to the top and bottom of the roll material. This allows for the auxiliary cleaning of dust and larger stains on the roll material as it moves through the take-up roller. The cleaning cloth 12 enhances the cleaning effect on the roll material, and the Velcro allows for easy replacement of the cleaning cloth 12, ensuring the cleaning effect on the roll material. When the cleaning cloth 12 needs to be replaced, it can be directly removed from the cleaning plate. After replacement or cleaning, the cleaning cloth 12 can be placed back on the cleaning plate and fixed by the adhesion between the two Velcro straps.
[0029] Furthermore, such as Figure 2 and Figure 3 As shown, the inner wall of the adjusting frame 3 is provided with a guide groove 14, and a guide block is slidably connected in the guide groove 14. One end of the guide block extends out of the guide groove 14 and is fixedly connected to the lifting frame 72. During operation, the guide groove 14 and the guide block facilitate the movement of the lifting frame 72 and prevent the lifting frame 72 from being subjected to excessive pressure due to the movement of the roll material.
[0030] Furthermore, such as Figure 1 and Figure 2 As shown, the inner wall of the adjusting frame 3 is provided with a first scale line 15, and the top of the base 1 is provided with a second scale line. During operation, the movement of the lifting frame 72 and the movement distance of the transmission plate 75 can be precisely controlled by setting the first scale line 15 and the second scale line.
[0031] Working principle: Based on the length of the roll material to be wound, rotating the first double-headed threaded rod 73 drives the two transmission blocks 74 on it to move the two positioning blocks 76 away from or close to each other. The transmission plate 75 drives the two guide rings 6 sliding on the outer wall of the guide roller 5 through the connecting plate 77 to move, so as to synchronously complete the adjustment of the limit of the roll material on the guide roller 5 and the adjusting roller. Before the roll material is passed through the adjusting frame 3 and wound onto the winding roller, the roll material is first passed between the two cleaning plates 11 and then wound onto the winding roller. Then the cylinder 71 is activated to drive the lifting frame 72 to rise, pulling up the part of the roll material located between the adjusting roller and the first double-headed threaded rod 73, so that the roll material is gradually tightened. Rotating the knob 13 drives the second double-headed threaded rod 10 to rotate, driving the two cleaning plates 11 to move closer to each other and fit against the top and bottom of the roll material. This allows the dust and larger stains on the roll material to be cleaned as it moves through the cleaning area via the winding roller. The cleaning cloth 12 enhances the cleaning effect of the roll material.
