Description

Technical Field

[0001] This utility model relates to the field of aluminum foil production technology, specifically to a tension adjustment device for an aluminum foil unwinding machine. Background Technology

[0002] The unwinding mechanism is a key part of aluminum foil production, mainly consisting of a cylindrical aluminum foil roll and an unwinding roller to support the roll. The unwinding roller is placed into the central cylindrical through-hole of the aluminum foil roll. Through the action of external feeding equipment and the rotation of the unwinding roller, one end of the aluminum foil is moved, thereby gradually separating the aluminum foil from the unwinding roller.

[0003] However, after the aluminum foil roll is placed on the unwinding roller, the lack of a tensioning mechanism on the unwinding roller results in low friction between the central columnar through-hole of the aluminum foil roll and the unwinding roller. This causes the aluminum foil roll and the unwinding roller to move asynchronously, which can easily lead to the aluminum foil roll becoming loose and the unwinding effect being poor. Summary of the Invention

[0004] This invention addresses the problem of low friction between the central columnar through-hole of the aluminum foil roll and the unwinding roller, which easily leads to the aluminum foil roll becoming loose. It provides a tension adjustment device for an aluminum foil unwinding machine, which can ensure the synchronous rotation of the unwinding roller and the aluminum foil roll, thereby improving the unwinding quality.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A tension adjustment device for an aluminum foil unwinding machine includes a vertical plate and a roller body, the roller body being rotatably connected to the vertical plate. It also includes an adjusting component, a connecting plate, and a top plate. The adjusting component includes a sleeve, a screw, and a connecting rod. The sleeve is disposed within the roller body, with its two ends fixedly connected to the left and right inner surfaces of the roller body, respectively. An array of sliding holes is arranged on the peripheral wall of the sleeve. A circular plate is slidably disposed within the sleeve, and a connecting rod corresponding to the sliding hole is connected to the circumferential surface of the circular plate. The end of each connecting rod passes through the corresponding sliding hole, and the end face of each connecting rod has a U-shaped groove with an opening facing the peripheral wall of the roller body. The screw is threadedly connected to the circular plate, with its right end rotatably connected to the right side plate of the roller body and its left end passing through the left side plate of the roller body. A connecting plate is installed in each U-shaped groove, and the connecting plate has an oblique hole with the right end higher than the left end. A sliding rod is installed in the oblique hole, with both ends connected to the sides of the corresponding U-shaped groove. Each connecting plate penetrates the peripheral wall of the roller body and connects to the top plate.

[0007] Furthermore, a support member is provided on the lower left side of the roller body. The support member includes a U-shaped plate and a support plate. The lower end of the support plate extends into the U-shaped plate and slides in contact with the inner side of the U-shaped plate. A hydraulic cylinder with its piston end facing upward is fixed on the inner bottom surface of the U-shaped plate. The piston end of the hydraulic cylinder is connected to the support plate. The upper end of the support plate is provided with an arc groove that matches the outer diameter of the roller body. A motor is fixed on the right side of the vertical plate. The output end of the motor passes through the vertical plate and connects to the right side plate of the roller body.

[0008] Furthermore, multiple top plates are located between the support plate and the upright plate; each top plate is an arc-shaped plate with arc-shaped edges at the left and right ends, the top plate protrudes away from the roller body, and the diameter of the circle containing each top plate is equal.

[0009] Furthermore, the thickness of each connecting plate corresponds to the width of the U-shaped groove, and the diameter of the sliding rod corresponds to the width of the inclined hole.

[0010] Furthermore, the left end of the screw is connected to a rotating plate one, and a threaded rod with its end facing the outside of the left side of the roller body is threadedly connected to the rotating plate one. The left end of the threaded rod is connected to a rotating plate two; the outside of the left side of the roller body is provided with anti-slip texture.

[0011] Furthermore, the roller body has multiple through holes on its peripheral wall for the connecting plates to pass through, and each connecting plate slides in contact with the corresponding through hole.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] In this invention, after the central columnar through-hole of the aluminum foil roll is fitted onto multiple top plates on the roller body, the adjusting component drives the multiple top plates to move synchronously away from the peripheral wall of the roller body. This causes the central columnar through-hole of the aluminum foil roll to be pressed and tightened by the multiple top plates, improving the connection between the aluminum foil roll and the roller body, preventing the aluminum foil roll from slipping when the roller body rotates, ensuring the synchronous rotation of the roller body and the aluminum foil roll, preventing the aluminum foil roll from becoming loose when unwinding, and improving the unwinding quality.

[0014] The threaded rod of this invention can limit the rotation of the screw when the roller rotates, preventing the top plate from changing position when the roller rotates, and maintaining the tension of multiple top plates on the aluminum foil roll. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figures 1-6 As shown, a tension adjustment device for an aluminum foil unwinding machine includes a vertical plate 1 and a roller body 2. The roller body 2 is rotatably connected to the vertical plate 1. It also includes an adjusting component, a connecting plate 3, and a top plate 4. The roller body 2 is a cylindrical body with its right end opening blocked by the right side plate. The adjusting component includes a sleeve 5, a screw 6, and a connecting rod 7. The sleeve 5 is a cylindrical body with an outer diameter smaller than the inner diameter of the roller body 2 and open at both ends. The sleeve 5 is coaxially disposed inside the roller body 2, and its two ends are fixedly connected to the left and right inner surfaces of the roller body 2, respectively. Sliding holes 8 are arrayed on the peripheral wall of the sleeve 5. The sliding holes 8 are rectangular holes arranged along the length of the sleeve 5. A circular plate 9 is slidably disposed inside the sleeve 5. Connecting rods 7 corresponding to the sliding holes 8 are connected to the circumferential surface of the circular plate 9. The end of each connecting rod 7 passes through the corresponding sliding hole 8. The connecting rod 7 is a rectangular rod that slides into the sliding hole 8. Each connecting rod 7 has a U-shaped groove 11 with its opening facing the circumferential wall of the roller body 2 on its end face. Both ends of each U-shaped groove 11 pass through the left and right sides of the connecting rod 7. The screw 6 is threadedly connected to the circular plate 9. The right end of the screw 6 is rotatably connected to the right side plate of the roller body 2, and the left end passes through the left side plate of the roller body 2. The left side plate of the roller body 2 has a through hole 12 for the screw 6 to pass through. Each U-shaped groove 11 is fitted with a connecting plate 3. The connecting plate 3 is a rectangular plate arranged along the length of the roller body 2. The connecting plate 3 has an oblique hole 13 with the right end higher and the left end lower. The oblique hole 13 is fitted with a sliding rod 14 with both ends connected to the side of the corresponding U-shaped groove 11. The sliding rod 14 is a round rod. Each connecting plate 3 passes through the circumferential wall of the roller body 2 and is connected to the top plate 4.

[0024] A support member is provided on the lower left side of the roller body 2. The support member includes a U-shaped plate 15 and a support plate 16. The front and rear ends and the upper end of the U-shaped plate 15 are open. The lower end of the support plate 16 extends into the U-shaped plate 15 and slides in contact with the inner side of the U-shaped plate 15. A hydraulic cylinder 17 with the piston end facing upward is fixed on the inner bottom surface of the U-shaped plate 15. The piston end of the hydraulic cylinder 17 is connected to the support plate 16. The upper end of the support plate 16 is provided with an arc groove 19 that matches the outer diameter of the roller body 2. A motor 18 is fixed on the right side of the vertical plate 1. The output end of the motor 18 passes through the vertical plate 1 and connects to the right side plate of the roller body 2.

[0025] Multiple top plates 4 are located between the support plate 16 and the upright plate 1; each top plate 4 is an arc plate with arc edges on the left and right ends, the top plate protrudes away from the roller body, the multiple top plates 4 are all the same in shape and size, the diameter of the circle in which each top plate 4 is located is equal, and there is a gap between each two adjacent top plates 4.

[0026] The thickness of each connecting plate 3 corresponds to the width of the U-shaped groove 11, and the diameter of the sliding rod 14 corresponds to the width of the inclined hole 13.

[0027] The left end of the screw 6 is connected to a rotating plate 20, and a threaded rod 21 with its end facing the outside of the left side of the roller body 2 is threadedly connected to the rotating plate 20. The left end of the threaded rod 21 is connected to a rotating plate 22. Anti-slip texture 24 is provided on the outside of the left side of the roller body 2.

[0028] The roller body 2 has multiple through holes 23 on its peripheral wall for the connecting plates 3 to pass through, and each connecting plate 3 slides in contact with the corresponding through hole 23.

[0029] In use, rotate the threaded rod 21 so that the end of the threaded rod 21 is away from the anti-slip texture 24. Rotate the screw 6. When the screw 6 rotates, the connecting rod 7 connected to the circular plate 9 is limited by the sliding hole 8. The connecting rod 7 can only slide left and right along the sliding hole 8. When the screw 6 rotates, it drives the circular plate 9 to move multiple connecting rods 7 to the right. Since the inclined hole 13 on the connecting plate 3 is higher on the right and lower on the left, when the connecting rod 7 moves to the right, it presses against the inclined hole 13 through the sliding rod 14 and drives the connecting plate 3 to move towards the sleeve 5. The connecting plate 3 moves towards the peripheral wall of the roller body 2 until the connecting plate 3 is close to the peripheral wall of the roller body 2. The hydraulic cylinder 17 drives the support plate 16 to move downward so that the support plate 16 is lower than the roller body 2. After the aluminum foil roll is sleeved on multiple top plates 4 through the central columnar through hole, rotate the screw 6 in the opposite direction to drive the circular plate 9 to move multiple top plates 4 to the right. When the connecting rod 7 moves to the left, the sliding rods 14 on the multiple connecting rods 7 press against the inclined holes, causing the connecting plate 3 to move away from the sleeve 5. The multiple top plates 4 move away from the roller body 2 simultaneously until the multiple top plates 4 press against the central columnar through hole of the aluminum foil roll. The central columnar through hole of the aluminum foil roll is tensioned, and the aluminum foil roll is firmly connected to the roller body 2. The hydraulic cylinder 17 drives the support plate 16 to move upward, and the arc groove 19 on the support plate 16 contacts the outer wall of the roller body 2. The threaded rod 21 is rotated in the opposite direction, so that the end of the threaded rod 21 presses against the anti-slip texture 24. When the motor 18 drives the roller body 2 to rotate and release the aluminum foil roll, the screw 6 does not rotate due to the rotation of the roller body 2, so as to avoid the multiple top plates 4 from changing the pressure on the aluminum foil roll. Thus, the synchronous movement of the aluminum foil roll and the roller body 2 is achieved, and the loosening of the aluminum foil roll is avoided when it is unwound.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
