Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil trimming, in particular to an edge compensation device used in the trimming process of an aluminum foil trimming machine. Background Art

[0002] Due to its excellent properties, aluminum foil is widely used in food, beverages, cigarettes, medicines, photographic plates, and household items. It is commonly used as packaging material for food, beverages, cigarettes, medicines, photographic plates, and household items; as a material for electrolytic capacitors; and as thermal insulation for buildings, vehicles, ships, and houses. It can also be used as decorative gold and silver thread, wallpaper, and decorative trademarks for various stationery, printed materials, and light industrial products. However, due to its soft material, aluminum foil inevitably leaves burrs at the cutting edge during the foil cutting process. These burrs can easily scratch the foil during the rolling process, and the protrusions from the burrs can easily cause the foil roll to shift during winding. Existing aluminum foil winding devices use a skewing device to correct the deviation during winding, but this deviation is difficult to correct.

[0003] To solve the above technical problems, the Chinese utility model patent with authorization announcement number CN205471892U discloses an aluminum foil winding device. Before the aluminum foil is rolled up, the utility model uses a pressing device to flatten the edge thorns of the aluminum foil before rolling it up, so as to avoid damage to the aluminum foil by the edge thorns and prevent the rolling from shifting due to the edge thorns. Secondly, a correction device is used on the fixed bracket to correct the displacement of the aluminum foil rolling to ensure neat rolling.

[0004] Although the technical solution provided by the utility model solves the problem that the deviation caused by the edge thorns of the existing aluminum foil winding device is difficult to correct, the aluminum foil will be cut according to actual needs, and the waste edges after cutting need to be collected and then recycled. Since the aluminum foil is thin, when it is rolled up, if the winding speed of the winding device is greater than the cutting speed, the aluminum foil will be subjected to a relatively large tensile force, which will cause the aluminum foil to break. If the winding speed of the winding device is less than the cutting speed, the aluminum foil will become chaotic or even entangled. Therefore, a compensation mechanism is needed in the aluminum foil winding process. Utility Model Content

[0005] The purpose of the utility model is to provide an edge trimming compensation device during the edge trimming process of an aluminum foil trimming machine, so as to solve the problems raised in the above background technology.

[0006] The embodiments of this application adopt the following technical solutions:

[0007] A trimming compensation device for an aluminum foil trimming machine during the trimming process comprises a mounting frame arranged between a trimming mechanism and a trimming mechanism, a compensation wheel which can move up and down being arranged on the top of the mounting frame, the aluminum foil cut by the trimming mechanism passing through the upper surface of the compensation wheel and then being wound onto the trimming mechanism, a mounting box being fixedly mounted on the top of the mounting frame, a driving motor which is communicatively connected to a main control board being fixedly mounted on the inner top wall of the mounting box, a threaded rod being fixedly connected to the output end of the driving motor, an inner threaded barrel being threadedly connected to the outer side of the threaded rod, and the compensation wheel being arranged below the inner threaded barrel.

[0008] Beneficial effects:

[0009] The utility model provides a compensation wheel that can move up and down between the trimming mechanism and the winding mechanism. When the slit aluminum foil is wound up, if the tension of the aluminum foil is too large, the compensation wheel can be controlled to descend, so that the tension of the aluminum foil can be reduced to avoid breakage. If the tension of the aluminum foil is too small, the compensation wheel can be controlled to rise to increase the tension of the aluminum foil, so that untimely winding can be avoided and the winding problem can be prevented.

[0010] Preferably, a tension sensor communicatively connected to the main control board is fixedly mounted on one end of the internally threaded barrel away from the driving motor, and the top of the compensation wheel is fixedly connected to the bottom of the tension sensor.

[0011] Preferably, guide rods are fixedly connected to both sides of the internal threaded barrel, and one end of the guide rod away from the internal threaded barrel is slidably connected to the inner wall of the installation box. A sliding groove adapted to the guide rod is provided on the inner wall of the installation box. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] To make the purpose, technical solutions, and advantages of this application more clear, the following will provide a clear and complete description of the technical solutions of this application in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0017] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0018] See also Figure 1-2 A device for compensating the edge of an aluminum foil trimming machine during trimming. The device comprises a mounting frame 4 disposed between a trimming mechanism 1 and a trimming mechanism 2. A compensating wheel 11 is disposed on top of the mounting frame 4 and is movable up and down. The aluminum foil 3 cut by the trimming mechanism 1 passes through the upper surface of the compensating wheel 11 and is then wound onto the trimming mechanism 2.

[0019] A mounting box 5 is fixedly mounted on the top of the mounting frame 4. A driving motor 6, which is in communication with the main control board, is fixedly mounted on the inner top wall of the mounting box 5. A threaded rod 7 is fixedly connected to the output end of the driving motor 6. The outer side of the threaded rod 7 is threadedly connected to an internally threaded barrel 8. A compensation wheel 11 is arranged below the internally threaded barrel 8.

[0020] A tension sensor 10 is fixedly mounted on one end of the internal threaded barrel 8 away from the drive motor 6 and is in communication with the main control board. The top of the compensation wheel 11 is fixedly connected to the bottom of the tension sensor 10. The specific model of the tension sensor 10 is DYMH-113.

[0021] Guide rods 9 are fixedly connected to both sides of the internal threaded barrel 8. One end of the guide rod 9 away from the internal threaded barrel 8 is slidably connected to the inner wall of the installation box 5. A sliding groove adapted to the guide rod 9 is opened on the inner wall of the installation box 5. The cooperation between the guide rod 9 and the sliding groove can limit the internal threaded barrel 8, prevent the internal threaded barrel 8 from rotating with the threaded rod 7, and make the internal threaded barrel 8 more stable during the up and down movement.

[0022] When the present invention is in use, the staff first passes the waste edge of the aluminum foil 3 cut by the trimming mechanism 1 through the compensation wheel 11, and then winds it onto the winding roller of the edge collection mechanism 2. When the winding speed of the edge collection mechanism 2 is greater than the unwinding speed of the edge trimming mechanism 1, the tension of the aluminum foil 3 between the edge trimming mechanism 1 and the edge collection mechanism 2 will increase, and the aluminum foil 3 will exert a downward force on the compensation wheel 11. At the same time, the tension sensor 10 can detect the magnitude of the tension. When the tension on the aluminum foil 3 is too large, the tension sensor 10 sends a signal to the main control board, and the main control board controls the rotation direction of the drive motor 6. At this time, the drive motor 6 will start to rotate, and the rotation of the drive motor 6 can drive the threaded rod 7 to rotate. The rotation of the threaded rod 7 can drive the internal threaded cylinder 8 to move downward, and then drive the compensation wheel 11 to move downward, thereby reducing the tension on the aluminum foil 3 and avoiding the aluminum foil 3 from breaking.

[0023] When the winding speed of the edge-rewinding mechanism 2 is lower than the unwinding speed of the edge-cutting mechanism 1, the aluminum foil 3 will be subjected to less tension or even no tension, and thus no downward pulling force will be applied to the compensation wheel 11. The tension sensor 10 sends a signal to the main control board, and the main control board controls the rotation direction of the drive motor 6 to drive the internal threaded cylinder 8 and the compensation wheel 11 to move upward, thereby avoiding the situation where the waste edges of the aluminum foil 3 are not wound up in time, and preventing the waste edges of the aluminum foil 3 from being entangled.

[0024] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
