[0004] Tension detection of aluminum foil rolls is primarily achieved through tension detectors, also known as tension sensors. These devices play a crucial role in the production and processing of aluminum foil rolls, accurately measuring the tension value of the roll material to ensure production stability and product quality. However, during tension detection, the aluminum foil rolls are subjected to significant tensile forces. Improper operation or excessive tension can easily lead to sudden breakage or ejection of the aluminum foil rolls, posing a safety threat to operators. Furthermore, the limited clamping area during operation can easily cause the aluminum foil rolls to slip or shift. Additionally, when subjected to high tension, the aluminum foil rolls are prone to breakage, affecting product integrity. Therefore, this invention provides an aluminum foil roll tension detection device. Utility Model Content

[0014] Beneficial effects

[0015] This invention provides an aluminum foil roll tension detection device. Compared with the prior art, it has the following advantages:

[0016] Firstly, this invention utilizes a rotating threaded bolt to allow the first clamping plate to slide along the inner wall of the mounting base. Then, a cone-shaped locking bolt engages with the first locking groove on the second clamping plate to clamp the aluminum foil roll, increasing the clamping area and making the clamping more secure. This effectively prevents the aluminum foil roll from slipping or shifting during the testing process. The lower end of the locking bolt, with its arc-shaped protective shaft, engages with the second locking groove to protect the top of the clamped aluminum foil roll, increasing the contact area at the top and preventing breakage due to excessive clamping force. This maintains the integrity of the aluminum foil roll. Furthermore, the slider bracket slides inside the slide rail bracket, causing the limiting bracket to slide on the slide rail bracket, limiting the movement of the aluminum foil roll and preventing shifting. Finally, the support plate provides support for the aluminum foil roll, reducing sagging or shifting caused by its own weight or external factors, ensuring the accuracy and reliability of the testing.

[0017] Secondly, the second and first protective shells of this utility model are rotatable on both sides of the mounting base via a support shaft, and then closed by the cooperation of the first and second magnet blocks. This allows for convenient and quick opening and closing of the protective shells without the need for complex latches or handles, improving operational efficiency. It is used to protect against tension testing of aluminum foil rolls, preventing excessive tension or improper operation from causing sudden breakage or ejection of the aluminum foil roll, which could result in accidental injury to the operator. The closed design of the second and first protective shells effectively prevents fragments from flying in such situations, protecting the operator's safety. Attached Figure Description

[0024] Example 1

[0025] See also Figure 1-4 This utility model provides a technical solution: an aluminum foil roll tension detection device, including a mounting base 1, on which a pulling mechanism for detecting aluminum foil roll tension is provided, the pulling mechanism including:

[0026] The protective assembly includes a fixing plate 2 fixedly connected to the two side walls of the mounting base 1, a support shaft 201 provided on both sides of the upper end of the fixing plate 2, a first protective shell 202 provided on the outer wall of the support shaft 201, and a first magnet block 3 provided on the upper inner wall of the first protective shell 202.

[0027] The mounting components include a mounting base 1 with a mounting seat 401 connected via a drive assembly. The upper end of the mounting seat 401 is provided with a threaded bolt 402, and the lower end of the threaded bolt 402 is provided with a first clamping plate 403. The inner wall of the first clamping plate 403 is provided with an anti-slip assembly for clamping aluminum foil roll film. The inner wall of the mounting seat 401 is fixedly connected with a second clamping plate 404. The lower end of the second clamping plate 404 is provided with a limiting bracket 703 connected via a push assembly, and the inner wall of the limiting bracket 703 is fixedly connected with a support plate 704.

[0028] In a preferred embodiment, a rotatable second protective shell 301 is provided on the rear side of the mounting base 1. A second magnet 302 is provided on the upper inner wall of the second protective shell 301. The second protective shell 301 and the first protective shell 202 are rotatable on both sides of the mounting base 1 via a support shaft 201. They are then closed by the cooperation of the first magnet 301 and the second magnet 302. This allows for convenient and quick opening and closing of the protective shells without the need for complex latches or handles, improving operational efficiency. It is used to protect against the tension of aluminum foil rolls during tension testing, preventing excessive tension or improper operation from causing the aluminum foil rolls to suddenly break or fly out, resulting in accidental injury to the operator. The closed design of the second protective shell 301 and the first protective shell 202 can effectively prevent fragments from flying in such situations, protecting the safety of the operator.

[0029] In a preferred embodiment, the drive assembly includes a bidirectional lead screw 4 disposed inside the mounting base 1. The mounting seat 401 is located on the outer wall of the bidirectional lead screw 4 and is threadedly connected. The mounting seat 401 is slidably connected to the mounting base 1. The two sets of mounting seats 401 are slid along the mounting base 1 under the action of the motor via the bidirectional lead screw 4, which is used to detect the tension of the clamped aluminum foil roll. The tension sensor is used to measure the tension value of the roll material during the tension control process. This is prior art and will not be elaborated further.

[0030] In a preferred embodiment, the anti-slip assembly includes a locking bolt 5 fixedly connected to the lower end face of a first clamping plate 403, a protective shaft 501 fixedly connected to the lower end of the locking bolt 5, a first locking groove 502 provided on the upper end face of a second clamping plate 404, and a second locking groove 503 provided at the lower end of the first locking groove 502. By rotating the threaded bolt 402, the first clamping plate 403 slides along the inner wall of the mounting base 401, and then the cone-shaped locking bolt 5 engages with the first locking groove 503 on the second clamping plate 404. The locking groove 502 clamps the aluminum foil roll, increasing the clamping area and making the clamping more secure. This effectively prevents the aluminum foil roll from slipping or shifting during the inspection process, thus avoiding slippage. Then, the arc-shaped protective shaft 501 at the lower end of the locking bolt 5 cooperates with the second locking groove 503 to protect the top of the clamped aluminum foil roll, increasing the contact area at the top and preventing the huge clamping force from causing the clamped aluminum foil roll to break, thus maintaining the integrity of the aluminum foil roll.

[0031] Example 2, the technical solution that differs from Example 1 includes:

[0032] In a preferred embodiment, the pushing assembly includes an electric push rod 6 fixedly connected to the inner wall of the mounting base 401. A push block 601 is provided at the end of the electric push rod 6. First rotating shafts 602 are provided on both sides of the push block 601. A connecting rod 603 is provided on the outer wall of the first rotating shaft 602. A second rotating shaft 702 is provided at the end of the connecting rod 603. A slide rail bracket 7 is fixedly connected to the lower end of the second clamping plate 404. A slider bracket 701 is provided inside the slide rail bracket 7. A limiting bracket 703 is located at the upper end of the slider bracket 701. The electric push rod... 6 drives the push block 601 to extend and retract. Then, the slider bracket 701 forms a rotating structure through the second rotating shaft 702, the connecting rod 603 and the push block 601, so that the slider bracket 701 can slide inside the slide rail bracket 7, and drive the limit bracket 703 to slide on the slide rail bracket 7 to limit the pulled aluminum foil roll film and prevent the phenomenon of deviation. Then, the support plate 704 provides a support force for the aluminum foil roll film, reducing the sagging or deviation of the aluminum foil roll film caused by its own weight or external factors, and ensuring the accuracy and reliability of the detection.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, rotating the threaded bolt 402 causes the first clamping plate 403 to slide along the inner wall of the mounting base 401. Then, the cone-shaped locking bolt 5 engages with the first locking groove 502 on the second clamping plate 404 to clamp the aluminum foil roll, increasing the clamping area and making the clamping more secure. This effectively prevents the aluminum foil roll from slipping or shifting during the inspection process, avoiding slippage. The lower end of the locking bolt 5 has an arc-shaped protective shaft 501 that engages with the second locking groove 503 to protect the top of the clamped aluminum foil roll, increasing its size. The contact area is determined by the electric push rod 6, which drives the push block 601 to extend and retract. The slider bracket 701 forms a rotating structure through the second rotating shaft 702, the connecting rod 603, and the push block 601, enabling the slider bracket 701 to slide inside the slide rail bracket 7. This drives the limit bracket 703 to slide on the slide rail bracket 7, which limits the pulled aluminum foil roll and prevents deviation. The support plate 704 provides a support force for the aluminum foil roll, reducing the sagging or deviation of the aluminum foil roll due to its own weight or external factors.

[0035] The second protective shell 301 and the first protective shell 202 are rotatable on both sides of the mounting base 1 via the support shaft 201. They are then closed by the cooperation of the first magnet block 3 and the second magnet block 302. This allows for convenient and quick opening and closing of the protective shells without the need for complex latches or handles, thus improving operational efficiency. It is used to protect against tension testing of aluminum foil rolls, preventing excessive tension or improper operation from causing the aluminum foil rolls to suddenly break or fly out, resulting in accidental injury to the operator.
