Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medicinal aluminum foil production, in particular to a slitting device for medicinal aluminum foil packaging production which can avoid wrinkles. Background Art
[0002] Medicinal aluminum foil, as a key material for pharmaceutical packaging, has the main function of protecting drugs from moisture, oxygen and light erosion, ensuring the effectiveness and safety of drugs.
[0003] Pharmaceutical aluminum foil is typically constructed from one or more layers of different materials. This composite structure is designed to provide barrier protection, shielding pharmaceuticals from direct contact with potentially harmful external substances. Pharmaceutical aluminum foil is often bonded to rigid sheets such as polyvinyl chloride (PVC) and polyvinylidene chloride (PVCD). It is used to package solid pharmaceuticals such as tablets and capsules. It exhibits excellent barrier properties, including water vapor and gas barriers, which are crucial for maintaining the stability and effectiveness of pharmaceuticals.
[0004] The medicinal aluminum foil slitting machine includes a fixed support structure, a cutting system, a dust collection system and an auxiliary positioning system. A winding roller for winding the medicinal aluminum foil is provided on one side of the cutting system. After winding, the wound aluminum foil is uniformly cut by the slitting mechanism of the medicinal aluminum foil slitting machine. The medicinal aluminum foil should have a clean, flat and evenly coated appearance. There should be no wrinkles in the production of medicinal aluminum foil packaging. Wrinkles are wrinkles on the surface of the aluminum foil that cannot be flattened longitudinally or transversely. The possibility of wrinkling increases with the decrease of the thickness of the aluminum foil during the winding process. In severe cases, continuous or intermittent wrinkles appear on the wound aluminum foil. In fact, the tension of the aluminum foil is not enough to flatten the aluminum foil during the winding process, and the pressure of the flattening roller on the material is inconsistent. As the thickness of the aluminum foil on the roller increases, the pressure of the flattening roller on the material changes. The inconvenience of adjustment causes the pressure of the flattening roller on the aluminum foil to be too loose or too tight, resulting in wrinkles, which leads to the winding and cutting of defective products.

[0015] In response to the problems raised in the background technology, in order to achieve precise control of pressure, the present application sets a pressure sensor and a controller on the winding roller of the aluminum foil slitting machine. The pressure sensor is used to monitor the actual pressure of the flattening roller on the aluminum foil in real time and send the data to the controller. The controller adjusts the length of the electric telescopic rod connected to the flattening roller through instructions based on the feedback from the pressure sensor. When the thickness of the aluminum foil increases, the flattening roller needs to increase the pressure on the aluminum foil to keep the aluminum foil flat. After detecting the pressure change, the pressure sensor transmits the information to the controller. The controller calculates the required adjustment amount and instructs the electric telescopic rod to perform a corresponding telescopic action to automatically adjust the pressure of the flattening roller on the aluminum foil to adapt to the change in the thickness of the aluminum foil and maintain a constant pressure to avoid the formation of wrinkles.
[0016] The pressure sensor is located at the end of the output end of the electric telescopic rod.

The electric telescopic rod automatically extends and retracts according to the instructions of the controller to adjust the position and pressure of the flattening roller. The outer circumferential wall of its output end is connected to the adjustment frame. The pressure is adjusted by changing the length of the telescopic rod. The adjustment frame is connected to the flattening roller. According to the adjustment displacement of the electric telescopic rod, the pressure of the flattening roller on the aluminum foil is adjusted, realizing automatic control and adjustment, maintaining constant tension of the aluminum foil during the winding process, thereby avoiding the formation of wrinkles.

This combination not only improves production efficiency, but also ensures the high quality standards of the products.
