[0002] Aluminum foil rewinders are part of the production process after the finishing process and before slitting. Their primary purpose is to rewind aluminum foil to prevent sticking; inspect the material's surface quality and defects during the rewinding process; and wind substandard weight products into smaller rolls. However, during the unwinding process, as the foil roll's diameter decreases, the current system lacks a surface pressure roller mechanism, preventing it from effectively applying pressure to the roll.

[0041] like Figures 1 to 5 As shown, the present invention comprises a noodle pressing roller mechanism 1 which is transmission-connected to a noodle pressing roller driving mechanism 2;

[0042] The dough pressing roller driving mechanism 2 includes a driving motor 2-1, a worm 2-4 and a turbine 2-6 meshing with the worm 2-4, a driving shaft 2-7 passing through the turbine 2-6, two rope pulleys 2-12 mounted on the driving shaft 2-7 and two steel wire ropes 4 with one end fixed and wound around the rope pulleys 2-12;

[0043] The dough pressing roller mechanism 1 includes two parallel and inclined linear slide rails 1-4, a connecting seat 1-5 provided on the two linear slide rails 1-4, a mounting shaft 1-6 provided between the two connecting seats 1-5, and a dough pressing roller 1-7 rotatably mounted on the mounting shaft 1-6, and each connecting seat 1-5 is provided with a connecting sleeve 1-9;

[0044] The other ends of the two steel wire ropes 4 are connected to the two connecting sleeves 1-9 after passing through the two fixed pulleys 1-2 respectively, and the steel wire ropes 4 drive the surface pressure roller 1-7 to move closer to or away from the aluminum foil roll 3.

[0045] In this embodiment, both ends of the surface pressing roller 1-7 are rotatably mounted on the mounting shaft 1-6 through end bearings 1-12, and the mounting shaft 1-6 is provided with an axial retaining ring 1-8 for limiting the end bearings 1-12;

[0046] The connecting seat 1-5 is provided with a convex ring 1-51, and both ends of the mounting shaft 1-6 pass through the convex ring 1-51 and extend into the connecting seat 1-5;

[0047] The two fixed pulleys 1-2 are mounted on the frame 1-0 via the small shaft 1-1, and the two linear guide rails 1-4 are both mounted on the frame 1-0.

[0048] In this embodiment, a through hole 1-54 is provided in the connecting seat 1-5, the connecting sleeve 1-9 is inserted into the through hole 1-54, the internal thread of the connecting sleeve 1-9 is connected with an adjusting bolt 1-10, a waist-shaped hole 1-91 is provided on the outer wall of the connecting sleeve 1-9, and a rope hole 1-92 is provided on the top of the connecting sleeve 1-9. The other end of the wire rope 4 passes through the rope hole 1-92 and is connected through a wire rope buckle 1-11.

[0049] In this embodiment, the connecting seat 1-5 is provided with a transition portion 1-53 near the bottom of the through hole 1-54. The head of the adjusting bolt 1-10 is located at the transition portion 1-53. The adjusting bolt 1-10 drives the connecting sleeve 1-9 to move up and down along the height direction.

[0050] The side wall of the connecting seat 1-5 is provided with a radial hole, and a set screw 1-14 is passed through the radial hole. The set screw 1-14 extends into the waist-shaped hole 1-91 and abuts against the bottom of the waist-shaped hole 1-91.

[0051] In this embodiment, a bearing seat 2-5 for transmission installation at both ends of the worm 2-4 is provided on the frame 1-0, and one end of the worm 2-4 extending out of the bearing seat 2-5 is transmission-connected to the output shaft of the drive motor 2-1 through a coupling 2-3, and a support 2-2 for the coupling 2-3 to pass through is provided on the frame 1-0.

[0052] In this embodiment, the two ends of the drive shaft 2-7 extending from the sheave 2-12 are rotatably mounted on the frame 1-0 through the lower bearing 2-9, and the turbine 2-6 is sleeved on the end of the drive shaft 2-7 extending from the frame 1-0;

[0053] A spacer sleeve 2-11 is provided between the rope pulley 2-12 and the lower bearing 2-9, and the spacer sleeve 2-11 is sleeved on the drive shaft 2-7. A groove 2-13 is provided on the rope pulley 2-12, and one end of two steel ropes 4 is wound around the grooves 2-13 of the two rope pulleys 2-12.

[0054] In this embodiment, it should be noted that Figure 1 In the initial state, when the aluminum foil roll 3 is installed, there is a gap between the aluminum foil roll 3 and the surface pressing rollers 1-7, which satisfies the bonding requirement during subsequent unwinding.

[0055] In this embodiment, the connecting seat 1-5 is connected to the slider of the linear slide rail 1-4 through a connecting bolt 1-52.

[0056] The purpose of setting a convex ring near the connecting seat 1-5 to the installation shaft 1-6 is to increase the thickness of the connecting seat 1-5 to facilitate the interference fit installation of the installation shaft 1-6 and reduce the weight of the connecting seat 1-5.

[0057] In this embodiment, the driving motor 2-1 is provided to provide driving force so that the worm 2-4 and the turbine 2-6 rotate to drive the rope wheel 2-12 to rotate, thereby realizing the rope releasing or rope taking-up action of the wire rope 4.

[0058] In this embodiment, in actual use, a through hole is opened on the rope wheel 2-12, and one end of the two steel ropes 4 passes through the through hole and is fixedly connected by a wire rope buckle, so that one end of the two steel ropes 4 is fixed and wound on the rope wheel 2-12.

[0059] In this embodiment, in actual use, two fixed pulleys 1-2 are provided to orient the other end of the steel wire rope 4 to facilitate movement requirements.

[0060] In this embodiment, in actual use, an adjusting bolt 1-10 is provided, and the adjusting bolt 1-10 and the connecting sleeve 1-9 are internally threadedly connected. This is so that by screwing the adjusting bolt 1-10, the connecting sleeve 1-9 is adjusted to move up and down along the height direction of the through hole 1-54, so as to meet the height requirement of the connecting sleeve 1-9 extending out of the top of the connecting seat 1-5, adapt to the connection needs of the other end of the wire rope 4, and improve the adaptability range.

[0061] In addition, the set screw 1-14 is provided to release the locking of the set screw 1-14 when the adjusting bolt 1-10 is screwed; after adjustment, the set screw 1-14 is inserted into the waist-shaped hole 1-91 and abuts against the bottom of the waist-shaped hole 1-91, thereby realizing the locking of the connecting sleeve 1-9 by the set screw 1-14, which is convenient for subsequent movement and pulling.

[0062] When the utility model is used specifically, during the unwinding process of the aluminum foil roll 3, the driving motor 2-1 rotates, and the driving shaft 2-7 and two rope pulleys 2-12 installed on the driving shaft 2-7 are driven to rotate through the worm 2-4 and the turbine 2-6. The rotation of the rope pulley 2-12 drives the steel wire rope 4 to unwind. When the steel wire rope 4 is unwound, the mounting shaft 1-6 and the surface pressure roller 1-7 move downward along the inclined linear slide rail 1-4 by their own weight through the connecting seat 1-5, so that the surface pressure roller 1-7 moves close to and away from the aluminum foil roll 3, so that the surface pressure roller 1-7 always fits the surface of the aluminum foil roll 3, thereby adapting to the change of the roll diameter from large to small when the aluminum foil roll is unwound, and meeting the requirements of aluminum foil rewinding;

[0063] Afterwards, the drive motor 2-1 can be operated to rotate in the opposite direction, and the wire rope 4 is retracted to drive the installation shaft 1-6 and the surface pressure roller 1-7 to move up and away from the inclined linear slide rail 1-4 through the connecting sleeve 1-9 and the connecting seat 1-5 to reset to facilitate the next aluminum foil rewinding requirement.

[0064] To sum up, the utility model has a simple structure and a reasonable design. Under the action of the surface pressure roller driving mechanism, the surface pressure roller slides along the linear slide rail through the steel wire rope, thereby adapting to the change of the roll diameter from large to small when the aluminum foil roll is unwound, ensuring that the surface pressure roller always fits the surface of the aluminum foil roll and meets the requirements of aluminum foil rewinding.

[0065] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
