Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum foil slitting machines, and particularly relates to an adjusting structure used for aluminum foil slitting machines. Background Art

[0002] Aluminum foil needs to be slit on a slitting machine after printing, cutting large rolls of semi-finished products into the required sizes. The unwinding and rewinding process involves controlling both machine speed and tension. Existing technology typically employs a roller in front of the rewinding roller to contact the foil and apply force to control tension. However, this type of tensioning applies localized force to the foil, which can lead to unevenness in the foil.

[0003] The document with authorization announcement number CN221625360U discloses a tension adjustment mechanism for an aluminum foil slitting machine, comprising a frame device for supporting and connecting the aluminum foil slitting machine, a force-applying device mounted in the middle of the frame device for swinging and applying tensioning force in a balanced manner from both ends, a conductive device for transmitting tensioning force provided on the force-applying device, and riveted together with the conductive device; the force-applying device comprises two support plates arranged symmetrically front and back, two pressure rollers symmetrically mounted between the support plates, symmetrically provided with limiting edges at both ends of the pressure rollers, and a rotating shaft provided in the middle of the outer side of the support plates. The rotating shaft drives the two pressure rollers on the support plates to swing, making the force on the aluminum foil more uniform, and the pre-compression amount is adjusted by connecting the swing arm to the rotating shaft, ultimately achieving the effect of adjusting the tension.

[0004] However, the device still has the following problems: the rotation of the shaft causes the swing arm to swing in an arc trajectory, which leads to rigid wear between the adjustment stud and the open slot, and the spring will also suffer from uneven force due to the swing of the swing arm, reducing the service life of the device.

[0031] In addition, the terms "first", "second", etc. are only used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0032] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, terms such as "disposed" and "connected" should be understood broadly. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0033] This embodiment provides a lining paper aluminum foil composite device, as shown in the attached Figure 1 -Attached Figure 4 As shown, along the transmission direction of the aluminum foil a, it includes a tension adjustment unit 1, a detection unit 2 and a winding unit 3; specifically,

[0034] The tension adjustment unit 1 includes a first bracket 11, two fixed plates 12 mounted on both sides of the first bracket 11 and arranged opposite to each other, and two adjusting rollers 13 arranged between the two fixed plates 12 and parallel to each other. Each side end of the fixed plate 12 is provided with a rotating rod 14 rotatably connected to the first bracket 11, and one or two rotating rods 14 are connected to one or two first motors 15 mounted on the first bracket 11.

[0035] The detection unit 2 includes a second bracket 21, a guide roller 22 rotatably mounted on the second bracket 21, and a tension sensor 23 disposed at a connection between the second bracket 21 and the guide roller 22. Furthermore, the detection unit 2 also includes a controller 24 electrically connected to the first motor 15, the tension sensor 23, and the second motor 33.

[0036] The winding unit 3 includes a third bracket 31 , a winding roller 32 rotatably disposed on the third bracket 31 , and a second motor 33 for driving the winding roller 32 to rotate.

[0037] It is worth noting that the specifications of the two adjusting rollers 13 can be the same or different, and their axes are located at the same horizontal height. The aluminum foil a is wound around the two adjusting rollers 13 respectively. After the specifications of the adjusting rollers 13 are determined, the distance between the highest point and the lowest point of the aluminum foil a when passing through the two adjusting rollers 13 can be adjusted by adjusting the overall rotation angle of the two adjusting rollers 13. The greater the distance, the greater the tension exerted by the adjusting rollers 13 on the aluminum foil a. When the rotation speed of the winding roller 32 remains unchanged, the tension sensor 23 located on the guide roller 22 can monitor this change and transmit it to the controller 24. After receiving the test data, the controller 24 can adjust the tension by controlling the first motor 15 or the second motor 33. The first motor 15 can adjust the rotation angle of the adjusting roller 13 to increase or decrease the tension exerted by the adjusting roller on the aluminum foil a, while the second motor 33 can adjust the tensioning effect of the aluminum foil a by adjusting the rotation speed. The two motors can also be adjusted simultaneously to achieve a synergistic effect. The controller 24 and the connection method of the controller 24 are well known in the art and will not be described in detail. Furthermore, the two rotating rods 14 are respectively arranged at the center of the two fixed plates 12 and are fixedly connected to the fixed plates 12. The connection method can be welding, etc. One of the rotating rods 14 can be rotatably connected to the first bracket 11 by a bearing, etc., and the other rotating rod 14 extends to the outer end of the first bracket 11 and is connected to a first motor 15, so that the first motor 15 drives the rotating rod 14 to rotate.

[0038] Specifically, the tension adjustment unit 1 also includes a rotating hole 16 provided on the first bracket 11 and through which the rotating rod 14 passes, a driven gear 17 provided on the end of the rotating rod 14, and a driving gear 18 provided on the output shaft of the first motor 15 and meshingly connected with the driven gear 17. The meshing connection of the gears can improve the accuracy of the angle at which the rotating rod 14 is driven by the first motor 15 to rotate, and has better support and stability, which is beneficial to improving the service life of the device. It can be understood that bearings 19 are provided at the connection between the rotating rod 14 and the rotating hole 16, the connection between the rotating rod 14 and the driven gear 17, and the connection between the driving gear 18 and the output shaft of the first motor 15. This arrangement helps to improve the stability of each rotating connection. The specific structure of the bearing 19 is a commonly used element for those skilled in the art, so it will not be repeated in this embodiment.

[0039] As a further preferred embodiment of the present invention, the tension adjustment unit 1 further includes two limiting convex rings 135 provided on both sides of the adjustment roller 13. The setting of the limiting convex rings 135 is mainly used to prevent the aluminum foil from falling off and improve the stability and uniformity of transmission.

[0040] As a further preferred embodiment of this embodiment, the tension adjustment unit 1 further includes a fixing groove 121 provided on the fixing plate 12 and for inserting the roller shaft of the adjusting roller 13, and a ball 122 provided on the outer peripheral side of the roller shaft of the adjusting roller 13 and rotatably connected to the fixing groove 121. The fixing groove 121 is provided on the surface of the fixing plate 12 facing away from the mounting rotation rod 14, and is installed at the same height as the mounting height of the rotation rod 14. This arrangement has the advantage of achieving a detachable connection between the adjusting roller 13 and the fixing plate 12, thereby enabling the installation of adjusting rollers 13 of different specifications based on the tension requirements in actual scenarios and the specifications of the aluminum foil, thus having the advantage of strong practicality.

[0041] As a further preferred embodiment of this embodiment, the tension adjustment unit 1 further includes a limiting rod 131 disposed on a side of the adjusting roller 13 near the first bracket 11 and parallel to the rotating rod 14; an arcuate track 132 disposed on the first bracket 11 and matching the motion trajectory of the limiting rod 131 for sliding connection with the limiting rod 131; a threaded section 133 disposed on an end of the limiting rod 131 away from the side of the adjusting roller 13; and an internally threaded ring 134 screwed onto the threaded section 133. The distance between the two limiting rods 131 is greater than the length of the fixing plate 12.

[0042] When the rotating rod 14 is driven to rotate the fixed plate 12 and thereby drive the two adjusting rollers 13 to rotate in opposite directions, the two limiting rods 131 slide within the arcuate track 132. The layout and length of the arcuate track 132 can also limit the maximum and minimum rotation angles of the adjusting roller 13. In this embodiment, the arcuate track 132 is symmetrical with the adjusting roller 13 as the rotation center, so that the rotation angle of the adjusting roller 13 is preferably between -60 degrees and 60 degrees. In addition, the sliding connection between the limiting rod 131 and the arcuate track 132 can strengthen the connection between the adjusting roller 13 and the first bracket 11, thereby dispersing the force between the rotating rod 14 and the gears of the first motor 15. In this way, in addition to the support of the adjusting roller 13 by the fixed plate 12, the first bracket 11 can also provide additional support for the adjusting roller 13, which helps to increase the service life of the device.

[0043] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
