[0001] This utility model relates to the field of unwinding mechanisms, specifically a novel unwinding mechanism for a slitting machine. Background Technology

[0002] The components of the uncoiling mechanism of the thin shearing machine vary in model and specification due to the different equipment periods they are from, causing many problems for normal inspection and maintenance, as well as the procurement and use of spare parts. In particular, the expansion shaft and its fixing base are not standardized, and different uncoilers use different specifications of air expansion shafts, causing confusion in normal production and significantly reducing production efficiency. In actual production, some aluminum foil rolls after slitting require secondary processing on the slitting machine due to different requirements or other reasons. However, the expansion shaft specifications used in the uncoiling mechanism of the thin shearing machine are different from those of other models, resulting in incompatibility issues between different uncoiling mechanisms due to the different expansion shafts. This makes it difficult to quickly achieve secondary uncoiling processing on the slitting machine after uncoiling on the thin shearing machine, leading to difficulties in production and maintenance.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3 As shown in the figure, a novel unwinding mechanism for a slitting machine according to an embodiment of this application includes:

[0022] The ground-fixed base 1 is used for the expansion shaft base 2, the air expansion shaft 5 on it, and the power transmission mechanism 4, thereby making the whole structure more stable.

[0023] An expansion shaft base 2 is disposed on the ground fixed base 1, thereby enabling the expansion shaft base 2 to be fixedly connected to the ground fixed base 1 and giving the expansion shaft base 2 good stability. The expansion shaft base 2 includes a semi-circular fixed cover 21 and a semi-circular movable cover 22 corresponding to the fixed cover 21. The fixed cover 21 and the movable cover 22 are used to fix the air expansion shaft 5. The semi-circular structure of the fixed cover 21 and the movable cover 22 is used to accommodate the air expansion shaft 5, thereby fixing the air expansion shaft 5 through the cooperation of the fixed cover 21 and the movable cover 22.

[0024] An expansion shaft locking mechanism 3 is located on at least one side of the expansion shaft base 2 and is used to lock the fixed cover 21 and the movable cover 22. The expansion shaft locking mechanism 3 allows the fixed cover 21 and the movable cover 22 to be locked or unlocked. In the unlocked state, the movable cover 22 is detachable from the fixed cover 21, thereby making the air expansion shaft 5 detachable relative to the expansion shaft base 2. In the locked state, the fixed cover 21 and the movable cover 22 are locked together, thereby fixing the air expansion shaft 5 between the fixed cover 21 and the movable cover 22. In this embodiment, the expansion shaft locking mechanism 3 is a threaded locking structure. Of course, in other optional embodiments, the specific implementation of the expansion shaft locking mechanism 3 can be adjusted according to actual needs.

[0025] The power transmission mechanism 4 is used to transmit power to the air expansion shaft 5 located in the expansion shaft base 2, so that the power transmission mechanism 4 rotates to make the air expansion shaft 5 rotate, thereby causing the material on the air expansion shaft 5 to rotate.

[0026] In this embodiment, in the initial unlocked state, the movable cover 22 is separated from the fixed cover 21. According to the size of the expansion shaft mechanism in the preceding thin shearing machine, the corresponding air expansion shaft 5 is installed on the fixed cover 21. The movable cover 22 and the fixed cover 21 are closed to place the air expansion shaft 5 therein. Then, the movable cover 22 and the fixed cover 21 are locked by the expansion shaft locking mechanism 3, and the power transmission mechanism 4 is connected to the air expansion shaft 5. Then, the rotation of the power transmission mechanism 4 drives the air expansion shaft 5 to rotate, thereby causing the material on the air expansion shaft 5 to rotate.

[0027] The above structure enables the air shaft 5 between different uncoiling mechanisms to be quickly compatible, and to quickly realize the secondary uncoiling process on the slitting machine after the thin shearing machine uncoils. This ensures that the uncoiling mechanism on the slitting machine is kept in the same size as the uncoiling mechanism of the preceding thin shearing machine, reducing the ineffective working time of operators, lowering production costs, and making inspection and maintenance operations faster and more efficient.

[0028] Specifically, the fixed cover 21 has a fixing nut 211 on its side, and the movable cover 22 has a clearance through hole corresponding to the fixing nut 211. The expansion shaft locking mechanism 3 includes a connecting screw 31 and a clamping nut 32 connected by bolts. One end of the connecting screw 31 is connected to the clamping nut 32, and the other end of the connecting screw 31 passes through the clearance through hole and is connected to the fixing nut 211. Thus, the connecting screw 31 connects the fixing nut 211 and the clamping nut 32 respectively, so that when facing air expansion shafts 5 of different sizes, the threaded connection of the clamping nut 32 to the connecting screw 31, combined with the locking effect of the clearance through hole wall, achieves a better locking effect. With the above structure, the movable cover 22 and the fixed cover 21 can have a good connection effect, improving the compatibility with air expansion shafts 5 of different sizes, and making the locking effect between the movable cover 22 and the fixed cover 21 better.

[0029] Specifically, the bottom end of the fixed tile cover 21 is connected to the ground fixed base 1, and the height of the movable tile cover 22 is less than the height of the fixed tile cover 21, so that the fixed tile cover 21 has a better support effect, and thus the movable tile cover 22 has better stability.

[0030] Specifically, the power transmission mechanism 4 includes a magnetic powder clutch 41 and a coupling wheel 42 connected to the magnetic powder clutch 41. The magnetic powder clutch 41 is used to stably transmit a constant torque, thereby easily and effectively controlling the rotational speed of the air shaft 5. The coupling wheel 42 is used to connect to the air shaft 5 located in the air shaft base 2, thereby enabling the air shaft 5 and the magnetic powder clutch 41 to have a good synchronous rotation effect.

[0031] Specifically, the ground fixing base 1 has a plate-like structure and a flat bottom, which gives the ground fixing base 1 good stability, thereby making the expansion shaft base 2 and the power transmission mechanism 4 located on it more stable during operation.

[0032] Specifically, the ground fixing base 1 has connecting holes, and the power transmission mechanism 4 and the expansion shaft base 2 are respectively connected to different connecting holes. That is, both the power transmission mechanism 4 and the expansion shaft base 2 are connected to the ground fixing base 1 through connecting holes on the ground fixing base 1. In this embodiment, both the power transmission mechanism 4 and the expansion shaft base 2 are bolted to the ground fixing base 1, thereby making them detachable and providing good connection stability. Of course, in other optional embodiments, the power transmission mechanism 4 and the expansion shaft base 2 can be connected to the ground fixing base 1 in other ways.

[0033] Specifically, the expansion shaft base 2 also includes a bearing sleeve 23, which is located between the fixed cover 21 and the movable cover 22 and abuts against the inner walls of the fixed cover 21 and the movable cover 22. The air expansion shaft 5 passes through the bearing sleeve 23. Thus, in the process of fixing different air expansion shafts 5, the tightness of the bearing sleeve 23 itself is adjusted to adapt to the corresponding air expansion shaft 5 specifications, thereby achieving a good fixing effect in the process of fixing different air expansion shafts 5.

[0034] This utility model uses specific embodiments to illustrate the principle and implementation of the utility model. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
