Abstract

The application relates to a novel aluminum foil cutter. The cutter comprises a cylindrical body, a cutter is arranged on the outer circumferential surface of the body, a bearing is arranged on the body, an elastic compacting device is arranged on the outer surface of the bearing, and the spacing between the outer surface of the elastic compacting device and the body corresponds to the spacing between the top end of the cutter and the body. By arranging the bearing and the elastic compacting device on the bearing, the aluminum foil can be pressed by the cutter and pressed by the elastic compacting device at the same time.

Description

Technical Field

[0001] This application relates to the field of aluminum foil cutter technology, and in particular to a novel aluminum foil cutter. Background Technology

[0002] Aluminum foil processing involves transporting flat aluminum foil sheets via conveyor belts or similar devices. Cutters are positioned along the transport path to cut the aluminum foil sheets as they pass through, separating wider sheets into narrower pieces for subsequent processing. However, in existing technologies, the cutting process inevitably applies force to the aluminum foil, potentially causing it to arch or wrinkle, affecting subsequent processing steps. Therefore, specialized methods are needed to smooth the foil, impacting work efficiency. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this application is to provide a novel aluminum foil cutter, comprising a cylindrical body. A cutter is provided on the outer circumferential surface of the body, and a bearing is fitted onto the body. An elastic compaction device is provided on the outer surface of the bearing, and the distance between the outer surface of the elastic compaction device and the body corresponds to the distance between the tip of the cutter and the body.

[0004] Preferably, there are at least two bearings, the cutter is located in the middle of the body, and the two bearings are located on both sides of the cutter along the extension direction of the body. The number of elastic compaction devices corresponds to the number of bearings.

[0005] Preferably, the outer surface of the main body is provided with a limiting surface to restrict the movement of the bearing in the cutting direction.

[0006] Preferably, the main body is detachably connected to a fixing device that mates with the limiting surface.

[0007] Preferably, the elastic compaction device is a sponge ring.

[0008] Preferably, the elastic compaction device further includes a connecting steel ring, a sponge ring sleeved and fixedly connected to the outer surface of the connecting steel ring, and the steel ring sleeved on the outer surface of the bearing.

[0009] Preferably, the cutter is a wear-resistant cutter.

[0010] In summary, this application includes the following beneficial technical effects: by setting a bearing and installing an elastic compaction device on the outer sleeve of the bearing, the aluminum foil can be pressed down by the elastic compaction device while being cut by the cutter. While the aluminum foil is pressed down, the elastic compaction device can rotate with the movement of the pressed aluminum foil based on the function of the bearing, so that the contact surface between the elastic compaction device and the aluminum foil is in a relatively static state. This ensures that the aluminum foil can remain flat when being cut by the cutter and prevents the aluminum foil from warping or wrinkling due to the force applied by the cutter.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. Regarding... Figure 4The existing aluminum foil cutters shown lack auxiliary pressing devices, causing the aluminum foil to wrinkle or curl due to the force applied by the cutter during cutting, thus losing its flatness. To address this, this application discloses a novel aluminum foil cutter, including a cylindrical body 1. In the prior art, the body 1 of a novel aluminum foil cutter 101 is typically cylindrical, with connecting holes 102 extending through both ends of the body 1 along its axial direction for connection to an external rotation control device. A cutter 101 is provided on the outer circumference of the body 1, used to cut the aluminum foil by pressing during rotation under the drive of the external rotation control device. A bearing 2 is fitted onto the body 1, and an elastic pressing device 3 is provided on the outer surface of the bearing 2 to press down the aluminum foil and prevent wrinkling. The distance between the outer surface of the elastic pressing device 3 and the body 1 corresponds to the distance between the top of the cutter 101 and the body 1. The elastic compaction device 3 can contact the aluminum foil simultaneously with the cutter 101. The elastic compaction device 3 presses down on the aluminum foil, and the passive rotation of the bearing 2, driven by the friction between the aluminum foil and the elastic compaction device 3, prevents the main body 1 from exerting additional force on the aluminum foil, thus avoiding any loss of flatness. Therefore, the distance between the outer surface of the elastic compaction device 3 and the main body 1 can be equal to the distance between the top of the cutter 101 and the main body 1, or the outer surface of the elastic compaction device 3 can slightly extend beyond the top of the cutter 101, thus applying a certain pressure to the aluminum foil based on the elasticity of the elastic compaction device 3. When the aluminum foil reaches the position of the cutter 101, driven by the conveyor belt or other conveying device, the elastic compaction device 3 presses down on the aluminum foil, and the cutter 101 cuts the aluminum foil, thus cutting it. The compaction effect of the elastic compaction device 3 resists wrinkling, warping, and other issues that may occur when the cutter 101 applies force to the aluminum foil, ensuring that the aluminum foil remains flat after being cut.

[0015] Furthermore, after the aluminum foil is cut into two, only one bearing 2 corresponds to one half of the elastic compaction device 3, which can only press one half. Although this invention can press both halves of the aluminum foil by connecting them in series, this application also provides a method. Specifically, there are at least two bearings 2, the cutter 101 is located in the middle of the body 1, and the two bearings 2 are located on both sides of the cutter 101 along the extension direction of the body 1. The number of elastic compaction devices 3 corresponds to the number of bearings 2. Thus, the aluminum foil cut into two by the cutter 101 can be pressed by the corresponding elastic compaction device 3.

[0016] Furthermore, to fix the position of the bearing 2 and prevent the elastic compaction device 3 from shifting when pressing the aluminum foil, the outer surface of the body 1 is provided with a limiting surface 103 to restrict the movement of the bearing 2 towards the cutter 101. Typically, the outer surface of the body 1 has a protrusion or a stepped outer surface to form the limiting surface 103 that blocks the bearing 2 from moving towards the cutter 101. The limiting surface 103 only blocks the bearing 2 from moving towards the cutter 101. To address the issue that the bearing 2 might move away from the cutter 101, causing it to detach from the body 1, the body 1 is detachably connected to a fixing device 4 that mates with the limiting surface 103. For example, a nut can be threaded onto the outer circumference of the body 1, or a fixing ring can be fitted around the body 1 with an interference fit, using conventional existing technologies. This allows the fixing device 4 and the limiting surface 103 to jointly clamp the bearing 2, especially the inner ring of the bearing 2, so that while the bearing 2 is fixed, its outer ring can rotate.

[0017] Furthermore, in order to properly press down the aluminum foil without applying excessive force to it, the elastic compaction device 3 is a sponge ring 301.

[0018] Furthermore, since the sponge ring 301 is fitted around the bearing 2, insufficient friction may prevent the sponge ring 301 from driving the bearing 2 to rotate under the frictional force between the aluminum foil and the sponge ring 301. If the sponge ring 301 is directly fixed to the bearing 2, it will damage the outer surface of the bearing 2. Even with adhesive bonding, residual adhesive will remain on the outer surface of the bearing 2, affecting its reusability. Therefore, the elastic compaction device 3 also includes a connecting steel ring 302. The sponge ring 301 is fitted and fixedly connected to the outer surface of the connecting steel ring 302, which is fitted onto the outer surface of the bearing 2. This ensures that the sponge ring 301 can drive the bearing 2 to rotate. Thus, whether the sponge ring 301 is connected to the steel ring 302 by adhesive bonding or other conventional fixing methods, it will not directly cause significant damage to the outer surface of the bearing 2. It also facilitates the replacement of the steel ring 302 and the sponge ring 301 as a whole during later maintenance and parts replacement.

[0019] Furthermore, the cutter 101 is a wear-resistant cutter with wear-resistant properties, as is common in the prior art, so as to have a longer service life.

[0020] Working Principle: Bearing 2 is fitted onto the outer circumference of body 1, and the inner ring of bearing 2 is fixed. Elastic compaction device 3 is fitted onto the outer surface of the outer circumference of bearing 2. Body 1 is connected to the rotating shaft of an external conventional cutting mechanism. The cutting mechanism is started, and its rotating shaft drives body 1 towards and rotates the aluminum foil, bringing both cutter 101 and elastic compaction device 3 into contact with the aluminum foil. During rotation, cutter 101 presses and cuts the aluminum foil. Driven by the transport device, the aluminum foil drives elastic compaction device 3 to rotate, which in turn causes bearing 2 to rotate. This ensures that the aluminum foil, after being cut, remains compacted by elastic compaction device 3 during transport, preventing wrinkles or warping due to the force applied by cutter 101 and ensuring the flatness of the aluminum foil.
