Description

Technical Field

[0001] The utility model relates to the field of metal foil processing, in particular to a metal foil transportation tension regulating mechanism. Background Art

[0002] The tension mechanism during metal foil winding is a key component to ensure winding quality. It consists of a tension sensor, a controller, and a mechanical actuator. The tension sensor detects the tension value of the metal foil in real time and transmits the signal to the controller for processing. The controller adjusts the action of the mechanical actuator according to preset parameters to keep the tension of the metal foil within a constant range. This mechanism has technical characteristics such as high precision, automated control, and flexibility, and can be applied to a variety of production scenarios and needs.

[0003] During the process of rolling and transporting metal foil, a tension adjustment mechanism is usually used to adjust the tension of the metal foil to ensure the transportation stability of the metal foil. However, there is a problem in actual use. Specifically, the tension detection roller needs to be cleaned before the metal foil is transported to avoid oil and stains on the surface that affect the accuracy of tension detection, thereby reducing its convenience of use. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a metal foil transport tension adjustment mechanism to solve the technical problem that it is inconvenient to clean the surface of the traditional tension detection roller.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a metal foil transport tension adjustment mechanism, comprising a support frame and a metal foil, wherein a tension detection roller, a first support roller and a second support roller are arranged on the inner side of the support frame, and a cleaning mechanism is arranged on the outer side of the tension detection roller, wherein the cleaning mechanism comprises a support sheet, and driven teeth and a support ring are respectively arranged at both ends of the support sheet, and one side of the driven teeth and the support ring is rotatably connected to the support frame through a thrust bearing, a motor is installed on one side of the support frame, and a driving tooth is arranged at the output end of the motor, and a cleaning sheet is affixed to the inner side of the support sheet.

[0006] By adopting the above technical solution, when the motor is started, it will drive the active teeth to start rotating. Since the active teeth and the driven teeth are meshed, the driven teeth will also rotate with the rotation of the active teeth. The rotation of the driven teeth will then drive the rotation of the supporting sheet. Since the supporting sheet and the tension detection roller are eccentrically arranged, during the rotation of the supporting sheet, its inner side will gradually approach the tension detection roller. As the supporting sheet continues to rotate, the cleaning sheet on the inner side will eventually contact the surface of the tension detection roller.

[0007] Furthermore, the driven teeth, the support ring and the central axis of the tension detection roller are arranged in parallel and are installed in an eccentric structure.

[0008] By adopting the above technical solution, the consistency of their spatial positions is ensured, which is conducive to maintaining the stability and balance of the entire cleaning mechanism. When the driven teeth are driven by the active teeth to rotate, since they are parallel to the central axis of the tension detection roller, the smoothness and accuracy of the rotation can be ensured, avoiding jamming or damage caused by position deviation.

[0009] Furthermore, the driving teeth and the driven teeth are meshed with each other, and the motor is electrically connected to an external power supply through a control center.

[0010] By adopting the above technical solution, when the motor starts, it will directly drive the active teeth to rotate, and the rotation of the active teeth will drive the driven teeth to rotate together through the meshing action, which not only realizes the effective transmission of power, but also ensures the synchronization and accuracy of rotation, thereby improving the working efficiency of the entire cleaning mechanism.

[0011] Furthermore, tension mechanisms are provided at both ends of the first support roller and the second support roller, and the tension mechanisms include slide grooves. The first support roller and the second support roller are both made of stainless steel.

[0012] By adopting the above technical solution, it is ensured that the metal foil can be subjected to uniform and stable tension during transportation. The slide groove in the tension mechanism allows the support roller to be fine-tuned within a certain range to adapt to metal foils of different widths and thicknesses, ensuring the flexibility and accuracy of tension adjustment. This setting helps to reduce problems such as wrinkling, loosening or breaking of the metal foil during transportation, thereby improving transportation stability and product quality.

[0013] Furthermore, bearing seats are installed at both ends of the first support roller and the second support roller, and the bearing seats are slidably connected to the slide groove, and a pressure spring is provided between the top of the bearing seat and the slide groove.

[0014] By adopting the above technical solution, the support roller can move flexibly in the chute, so that its position can be adjusted according to actual needs. This sliding connection not only improves the adjustability of the equipment, but also ensures that the support roller can remain stable when transporting metal foil, reducing tension fluctuations caused by position deviation.

[0015] Furthermore, both ends of the tension detection roller are connected to tension sensors via bearing seats, the tension sensor is fixedly connected to the support frame, the tension sensor is electrically connected to the controller, and the model of the tension sensor is XJC-ZL08.

[0016] By adopting the above technical solution, it is ensured that the tension detection roller can accurately transmit the tension signal during the rotation process. The fixed connection between the tension sensor and the support frame ensures the stability and reliability of the sensor during the detection process, avoiding detection errors caused by position changes.

[0017] In summary, the present invention has the following beneficial effects:

[0018] The utility model uses the cleaning mechanism to start the motor to drive the active gear to rotate. Since the active gear and the driven gear are meshed with each other, the driven gear will also rotate accordingly, thereby driving the supporting piece to start rotating. An eccentric design is adopted between the supporting piece and the tension detection roller, so when the supporting piece rotates, its inner side will gradually approach the tension detection roller. As the supporting piece continues to rotate, the cleaning piece on the inner side will eventually contact the surface of the tension detection roller. At this time, the tension detection roller can be rotated and its surface can be cleaned with the cleaning piece. At the same time, when the tension adjustment mechanism is not in working condition, the supporting piece will cover the top of the tension detection roller, which can effectively reduce the possibility of external dust falling on the surface of the tension detection roller, thereby providing better tension detection conditions for the next batch of metal foil transportation, not only improving the use convenience of the equipment, but also enhancing the convenience of cleaning, ensuring that the tension detection roller can be kept clean before each use, thereby improving the stability of metal foil transportation and product quality.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The following describes an embodiment of the present invention based on its overall structure.

[0029] Example 1:

[0030] A metal foil transport tension adjustment mechanism, such as Figure 1-Figure 5As shown, it includes a support frame 1 and a metal foil 4. A tension detection roller 201, a first support roller 202, and a second support roller 203 are arranged on the inner side of the support frame 1. A cleaning mechanism 5 is arranged on the outer side of the tension detection roller 201. The cleaning mechanism 5 includes a support sheet 501. Driven teeth 502 and a support ring 504 are respectively arranged at both ends of the support sheet 501. One side of the driven teeth 502 and the support ring 504 are rotatably connected to the support frame 1 through a thrust bearing 503. A motor 507 is installed on one side of the support frame 1, and a driving tooth 506 is arranged at the output end of the motor 507. A cleaning sheet 505 is attached to the inner side of the support sheet 501. When the motor 507 is started, it will drive the driving tooth 506 to start rotating. Since the driving tooth 506 and the driven tooth 502 is meshed, so the driven tooth 502 will also rotate with the rotation of the active tooth 506, and the rotation of the driven tooth 502 will drive the rotation of the support piece 501. Since the support piece 501 and the tension detection roller 201 are eccentrically arranged, the inner side of the support piece 501 will gradually approach the tension detection roller 201 during the rotation of the support piece 501. As the support piece 501 continues to rotate, the cleaning piece 505 on the inner side will eventually contact the surface of the tension detection roller 201. At this time, the tension detection roller 201 can be driven to rotate, and the cleaning piece 505 can be used to clean the dirt on its surface, which not only improves the convenience of use of the equipment, but also makes the cleaning work easier and more efficient, thereby ensuring the stability of the transportation of the metal foil 4 and the product quality.

[0031] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The driven teeth 502 and the support ring 504 are arranged parallel to the central axis of the tension detection roller 201 and are installed in an eccentric structure, which ensures the consistency of their spatial positions and is conducive to maintaining the stability and balance of the entire cleaning mechanism 5. When the driven teeth 502 are driven by the active teeth 506 to rotate, since they are parallel to the central axis of the tension detection roller 201, the smoothness and accuracy of the rotation can be ensured, and jamming or damage caused by position deviation can be avoided. At the same time, the eccentric structure installation allows the inner side of the support sheet 501 to gradually approach and eventually abut against the surface of the tension detection roller 201 during the rotation process, which not only realizes the effective contact between the cleaning sheet 505 and the surface of the tension detection roller 201, but also ensures the uniformity and comprehensiveness of the cleaning.

[0032] See Figure 5The driving teeth 506 and the driven teeth 502 are meshed, and the motor 507 is electrically connected to the external power supply through the control center. When the motor 507 is started, it will directly drive the driving teeth 506 to rotate, and the rotation of the driving teeth 506 will drive the driven teeth 502 to rotate together through the meshing action, which not only realizes the effective transmission of power, but also ensures the synchronization and accuracy of the rotation, thereby improving the working efficiency of the entire cleaning mechanism 5. At the same time, the motor 507 is electrically connected to the external power supply through the control center, so that the start, stop and speed adjustment of the motor 507 can be accurately controlled by the control center. In this way, the operator can conveniently control the operation of the cleaning mechanism 5 through the control center according to actual needs, thereby improving the operability and convenience of use of the equipment.

[0033] Example 2:

[0034] See Figure 1 、 Figure 2 、 Figure 3 , both ends of the first support roller 202 and the second support roller 203 are provided with a tension mechanism 3, the tension mechanism 3 includes a slide groove 302, and the material of the first support roller 202 and the second support roller 203 are both stainless steel, ensuring that the metal foil 4 can be subjected to uniform and stable tension during transportation. The slide groove 302 in the tension mechanism 3 allows the support rollers to be fine-tuned within a certain range to adapt to metal foils 4 of different widths and thicknesses, ensuring the flexibility and accuracy of tension adjustment. Such a setting helps to reduce problems such as wrinkles, looseness or breakage of the metal foil 4 during transportation, thereby improving transportation stability and product quality. At the same time, the material of the first support roller 202 and the second support roller 203 are both stainless steel. This choice brings many beneficial effects. Stainless steel has good corrosion resistance and wear resistance, which can extend the service life of the support rollers and reduce equipment failures and downtime caused by material problems.

[0035] See Figure 1 、 Figure 2 、 Figure 3 , bearing seats 301 are installed at both ends of the first support roller 202 and the second support roller 203, and the bearing seats 301 are slidably connected to the slide groove 302, and a pressure spring 303 is arranged between the top of the bearing seat 301 and the slide groove 302, so that the support roller can move flexibly in the slide groove 302, thereby adjusting its position according to actual needs. This sliding connection not only improves the adjustability of the equipment, but also ensures that the support roller can remain stable when transporting the metal foil 4, reducing the tension fluctuation caused by position deviation. At the same time, a pressure spring 303 is arranged between the top of the bearing seat 301 and the slide groove 302. The existence of the pressure spring 303 provides a certain pre-tightening force for the bearing seat, so that the support roller can quickly return to its original position when subjected to external force, thereby ensuring the stability and consistency of the tension.

[0036] See Figure 1 、 Figure 2 、 Figure 4 Both ends of the tension detection roller 201 are connected to a tension sensor 6 installed through a bearing seat. The tension sensor 6 is fixedly connected to the support frame 1. The tension sensor 6 is electrically connected to the controller. The model of the tension sensor 6 is XJC-ZL08, which ensures that the tension detection roller 201 can accurately transmit the tension signal during the rotation process. The fixed connection between the tension sensor 6 and the support frame 1 ensures the stability and reliability of the sensor during the detection process, and avoids the detection error caused by position change. At the same time, the tension sensor 6 is electrically connected to the controller, so that the tension signal detected by the sensor can be transmitted to the controller in a timely and accurate manner. The controller can adjust the operating status of the tension mechanism 3 in real time according to the received signal to ensure that the metal foil 4 is subjected to constant tension during transportation. In addition, the tension sensor 6 adopts a product with model XJC-ZL08. This type of sensor has high precision, high stability and good anti-interference ability, which further improves the accuracy and reliability of tension detection.

[0037] The working principle of the present invention is as follows: first, the metal foil is wound on the first support roller 202, the tension detection roller 201, and the second support roller 203. When the metal foil 4 is transported by the unwinder and the winder, the tension is adjusted by the tension mechanism 3 on both sides of the first support roller 202 and the second support roller 203, thereby ensuring the stability of the transportation of the metal foil 4.

[0038] During the transportation of the metal foil 4, the support sheet 501 is located below the tension detection roller 201. Due to its eccentric setting, the support sheet 501 is away from the tension detection roller 201, so as to avoid the existence of the cleaning mechanism 5 affecting the transportation and detection of the metal foil 4 by the tension detection roller 201. When the metal foil 4 is wound and transported, the motor 507 is started to drive the active gear 506 to rotate. Because it is engaged with the driven gear 502, the support sheet 501 is rotated. Since the support sheet 501 and the tension detection roller 201 are eccentrically set, as the support sheet 501 gradually rotates, the inner part of the support sheet 501 is The side gradually approaches the tension detection roller 201, causing the cleaning sheet 505 on the inside to gradually abut against the surface of the tension detection roller 201. After that, the tension detection roller 201 can be rotated to clean the surface of the tension detection roller 201 through the cleaning sheet 505 abutting against it. At the same time, because the supporting sheet 501 covers the top of the tension detection roller 201, when the tension adjustment mechanism is not in use, the degree to which external dust falls on the surface of the tension detection roller 201 can be reduced, thereby providing a better surface cleaning requirement for the tension detection roller 201 for the transportation of the next batch of metal foil 4, which is conducive to improving its ease of use and cleaning.
