Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for slitting machines, specifically a fully automatic tension control unwinding device for a double-sided guide fabric slitting machine. Background Technology

[0002] In the slitting and production process of double-sided flow guide fabric, tension control during the unwinding stage plays a decisive role in product quality. With the continuous development of industrial production, the requirements for the quality and production efficiency of double-sided flow guide fabric are increasing, and traditional unwinding devices are gradually revealing many problems.

[0003] Existing technologies have the following defects or problems: In existing unwinding equipment, some devices lack effective tension adjustment methods and cannot adjust the unwinding tension in real time based on factors such as the material characteristics of the double-sided guide fabric and changes in roll diameter. This leads to uneven tension in the double-sided guide fabric during the slitting process. When the tension is too low, the fabric surface becomes loose, resulting in wrinkles, severely affecting slitting accuracy and causing significant dimensional deviations in the slitting products, failing to meet production standards. Conversely, when the tension is too high, it overstretches the double-sided guide fabric, damaging its internal structure, reducing the physical properties of the product, and even causing the fabric to break, resulting in production interruptions and increased production costs.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fully automatic tension control unwinding device for a double-sided guide fabric slitting machine, which solves the current problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic tension control unwinding device for a double-sided guide fabric slitting machine, comprising a support frame, an unwinding frame fixedly connected to the top of the support frame, and an adjustment component provided on the surface of the unwinding frame;

[0007] The adjusting assembly includes a U-shaped groove formed on the surface of the unwinding frame. A second mounting plate is detachably mounted on one side wall of the unwinding frame. A guide plate is rotatably connected to the outer periphery of the second mounting plate. A connecting rod is fixedly connected to the end of the guide plate away from the second mounting plate. The connecting rod slides through the U-shaped groove. A threaded hole is provided at the end of the connecting rod away from the guide plate. An adjusting roller is detachably mounted at the end of the connecting rod away from the guide plate. An electric push rod is rotatably connected to the end of the guide plate away from the connecting rod. The end of the electric push rod away from the guide plate is rotatably connected to the surface of the unwinding frame.

[0014] 1. This fully automatic tension control unwinding device for a double-sided guide fabric slitting machine, through the setting of an adjustment component, allows the extension and retraction of an electric push rod to drive the guide plate to rotate, thereby causing the connecting rod to slide along the U-shaped groove, thus changing the position of the adjusting roller. During the unwinding process of the double-sided guide fabric, the relative position between the adjusting roller and the drive roller can be flexibly adjusted according to the actual tension requirements, precisely controlling the tension of the fabric roll. This effectively solves the problem that traditional devices cannot adjust the tension in real time, ensuring that the double-sided guide fabric is always in the optimal tension state during the slitting process, improving slitting accuracy, reducing defects such as wrinkles, stretching deformation, and breakage caused by uneven tension, and improving product quality.

Detailed Implementation

[0021] 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.

[0022] refer to Figure 1 and Figure 2 and Figure 3 In this embodiment: a fully automatic tension control unwinding device for a double-sided guide fabric slitting machine includes a support frame 1, an unwinding frame 2 fixedly connected to the top of the support frame 1, and an adjustment component provided on the surface of the unwinding frame 2;

[0023] The adjustment assembly includes a U-shaped groove 3, which is formed on the surface of the unwinding frame 2. A mounting plate 17 is detachably installed on one side wall of the unwinding frame 2. A guide plate 13 is rotatably connected to the outer periphery of the mounting plate 17. A connecting rod 15 is fixedly connected to the end of the guide plate 13 away from the mounting plate 17. The connecting rod 15 slides through the U-shaped groove 3. A threaded hole is provided at the end of the connecting rod 15 away from the guide plate 13. An adjusting roller 8 is detachably installed at the end of the connecting rod 15 away from the guide plate 13. An electric push rod 14 is rotatably connected to the end of the guide plate 13 away from the connecting rod 15. The end of the electric push rod 14 away from the guide plate 13 is rotatably connected to the surface of the unwinding frame 2.

[0024] Specifically, after receiving the signal from the pressure detector 4, the control system compares and analyzes the actual tension value with the preset tension value. If the actual tension is greater than the preset value, the control system issues a command to retract the electric push rod 14. When the electric push rod 14 retracts, it drives the guide plate 13 to rotate around the mounting plate 17. The rotation of the guide plate 13 causes the connecting rod 15 to slide upward along the U-shaped groove 3, thereby driving the adjusting roller 8 to move upward. After the adjusting roller 8 moves upward, the tension on the double-sided guide fabric is reduced, thus reducing the unwinding tension. Conversely, if the actual tension is less than the preset value, the control system controls the electric push rod 14 to extend, causing the adjusting roller 8 to move downward, increasing the tension on the double-sided guide fabric, and increasing the unwinding tension, thereby ensuring that the double-sided guide fabric maintains a stable tension during the unwinding process.

[0025] refer to Figure 1 , Figure 3 and Figure 4 In this embodiment, a screw 16 is fixedly connected to one end of the adjusting roller 8 near the connecting rod 15. The screw 16 is threadedly connected to the connecting rod 15. Screws 18 are threadedly connected to all four sides of the mounting plate 17. Multiple drive rollers 6 are provided on the side of the unwinding frame 2 away from the mounting plate 17. A pressure detector 4 is provided on the side of the unwinding frame 2 near the drive rollers 6. A heat dissipation grid 7 is provided on the outer wall of the pressure detector 4. An anti-slip rubber layer 5 is sleeved on the outer periphery of the drive rollers 6. An operation panel 9 is installed on the outer wall of the support frame 1. An installation plate 11 is installed on the outer wall of the support frame 1 near the operation panel 9. A warning light 10 is fixedly connected to the surface of the installation plate 11. A horn 12 is provided on the surface of the installation plate 11.

[0026] Specifically, when maintenance or replacement of the adjusting roller 8 is required, the operator can first turn off the equipment power, then unscrew the screws 18 around the mounting plate 17 to remove the mounting plate 17 from the unwinding frame 2. Next, unscrew the screw 16 on the adjusting roller 8 to separate the adjusting roller 8 from the connecting rod 15, thus completing the disassembly of the adjusting roller 8. During equipment operation, if the pressure detector 4 detects abnormal tension exceeding the adjustable range of the equipment, or if other parts of the equipment malfunction, the control system will control the warning light 10 to illuminate and activate the horn 12 to sound an alarm, reminding the operator to handle the situation promptly. The operator can view the equipment's fault information through the control panel 9 and make corresponding adjustments and repairs. The anti-slip rubber layer 5 sleeved on the outer periphery of the drive roller 6 increases the friction between it and the double-sided guide cloth, ensuring that the drive roller 6 can stably drive the double-sided guide cloth forward during unwinding, avoiding slippage and ensuring a uniform and stable unwinding speed, which also helps maintain stable tension.

[0027] The working principle and usage process of this utility model are as follows: After receiving the signal from the pressure detector 4, the control system compares and analyzes the actual tension value with the preset tension value. If the actual tension is greater than the preset value, the control system will issue a command to control the electric push rod 14 to retract. When the electric push rod 14 retracts, it drives the guide plate 13 to rotate around the mounting plate 17. The rotation of the guide plate 13 causes the connecting rod 15 to slide upward along the U-shaped groove 3, thereby driving the adjusting roller 8 to move upward. After the adjusting roller 8 moves upward, the tension on the double-sided guide cloth is reduced, thereby reducing the unwinding tension. Conversely, if the actual tension is less than the preset value, the control system will control the electric push rod 14 to extend, causing the adjusting roller 8 to move downward, increasing the tension on the double-sided guide cloth, and increasing the unwinding tension, thereby ensuring that the double-sided guide cloth maintains a stable tension during the unwinding process. When it is necessary to maintain or replace the adjusting roller 8, the operator can first turn off the power of the equipment, then unscrew the screws 18 around the mounting plate 17, and remove the mounting plate 17 from the unwinding frame 2. Next, unscrew the screw 16 on the adjusting roller 8 to separate the adjusting roller 8 from the connecting rod 15, thus completing the disassembly of the adjusting roller 8. During equipment operation, if the pressure detector 4 detects abnormal tension exceeding the adjustable range of the equipment, or if other components of the equipment malfunction, the control system will activate the warning light 10 and sound the alarm horn 12 to remind the operator to handle the situation promptly. The operator can view the equipment's fault information through the control panel 9 and make corresponding adjustments and repairs. The anti-slip rubber layer 5 on the outer periphery of the drive roller 6 increases the friction between it and the double-sided guide cloth, ensuring that the drive roller 6 can stably drive the double-sided guide cloth forward during unwinding, avoiding slippage and ensuring a uniform and stable unwinding speed, which also helps maintain stable tension.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
