Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical cold aluminum production technology, and in particular relates to a winding device for pharmaceutical cold aluminum production. Background Technology

[0002] Pharmaceutical-grade chilled aluminum foil is a high-purity aluminum foil material specifically designed for pharmaceutical packaging. It possesses excellent barrier properties, corrosion resistance, and sealing properties, effectively protecting pharmaceuticals from moisture, oxygen, and light, ensuring drug stability and extending shelf life. Its surface undergoes special treatment to meet pharmaceutical safety standards, and it is widely used in pharmaceutical blister packaging, aluminum-plastic composite films, and other pharmaceutical encapsulation fields. It is one of the key materials for ensuring drug quality and safety. Tension-controlled winding machines are a commonly used winding device in the production of pharmaceutical-grade chilled aluminum foil. By precisely adjusting and controlling the tension during the winding process, it ensures that the aluminum foil remains uniform and flat during winding, avoiding material damage or poor roll shape caused by tension fluctuations, thereby meeting the high cleanliness and precision requirements of pharmaceutical packaging for aluminum materials.

[0003] The problem with existing technology is that existing tension control winding machines usually lack the function of automatically cutting aluminum foil during use. This leads to the need for manual cutting, which is time-consuming and labor-intensive. In addition, during the cutting process, there is no function to compress the aluminum foil. After the aluminum foil is cut, if the aluminum foil on the winding roller is not compressed in time, the aluminum foil may become loose due to the loss of tension. At this time, manual sorting is required, which increases the labor intensity of the operators. Utility Model Content

[0026] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 4 As shown in the figure, a winding device for producing pharmaceutical cold aluminum provided in this embodiment of the present invention includes a winding machine body 1. Support plates 2 are fixedly connected to the left and right sides of the front side of the winding machine body 1.

[0028] refer to Figure 2 The left and right sides of the positioning roller 4 are rotatably connected to the support plate 2, and the left and right sides of the first cutter 5 are fixedly connected to the support plate 2.

[0029] The above solution is adopted: by setting the positioning roller 4, the aluminum foil can be positioned; by setting the first cutter 5, the second cutter 702 can be raised to a suitable position and cooperate with the second cutter 702 to cut the aluminum foil after it has been wound up.

[0030] refer to Figure 2 and Figure 3 Rectangular through holes 8 are provided on the left and right sides of the inner side of the support frame 3. A limiting post 9 is provided in the inner cavity of the rectangular through hole 8 to cooperate with the cutting device 7. The top and bottom of the limiting post 9 are fixedly connected to the inner wall of the rectangular through hole 8.

[0031] The above solution is adopted: by setting a rectangular through hole 8 and a limiting post 9, the lifting plate 701 can be limited, which facilitates the lifting plate 701 to rise and fall.

[0032] refer to Figure 4 The pressing device 6 includes a drive shaft 601, gears 602 are provided on both the left and right sides of the drive shaft 601, a rotating frame 603 is sleeved on the surface of the drive shaft 601, and a pressing roller 604 is provided on the inner side of the rotating frame 603 away from the drive shaft 601.

[0033] The above solution involves setting up a pressing device 6 to press the aluminum foil firmly, preventing it from becoming loose after being cut.

[0034] refer to Figure 4The cutting device 7 includes a lifting plate 701, a second cutter 702 is provided in the middle of the top of the lifting plate 701, toothed plates 703 are provided on the left and right sides of the rear side of the lifting plate 701, and an electric cylinder 704 is provided at the bottom of the lifting plate 701.

[0035] The above solution involves setting up a cutting device 7, which can cut the aluminum foil, making it convenient for operators to use the aluminum foil.

[0036] refer to Figure 3 and Figure 4 The left and right sides of the drive shaft 601 are fixedly connected to the gear 602. The opposite sides of the two gears 602 are rotatably connected to the support plate 2. The front side of the gear 602 meshes with the toothed plate 703. The rotating frame 603 is fixedly connected to the drive shaft 601. The left and right sides of the pressure roller 604 are fixedly connected to the rotating frame 603.

[0037] The above solution is adopted as follows: by setting gear 602, the transmission shaft 601 can be driven to rotate; by setting transmission shaft 601, the rotating frame 603 can be driven to rotate; by setting rotating frame 603, the pressure roller 604 can be driven to rotate; by setting pressure roller 604, the aluminum foil can be pressed when the aluminum foil is cut.

[0038] refer to Figure 3 and Figure 4 The left and right sides of the lifting plate 701 are both sleeved on the surface of the limiting post 9. The bottom of the second cutter 702 is fixedly connected to the lifting plate 701. The rear side of the toothed plate 703 is fixedly connected to the lifting plate 701. The top of the electric cylinder 704 is fixedly connected to the support frame 3. The output shaft of the electric cylinder 704 passes through the support frame 3 and extends to the inner side of the support frame 3 and is fixedly connected to the lifting plate 701.

[0039] The above scheme is adopted as follows: by setting up the lifting plate 701, the second cutter 702 and the toothed plate 703 can be driven to rise and fall. By setting up the second cutter 702, the aluminum foil can be cut. By setting up the toothed plate 703, the gear 602 can be driven to rotate. By setting up the electric cylinder 704, the lifting plate 701 can be driven to rise and fall.

[0040] The working principle of this utility model:

[0041] When in use, one end of the aluminum foil to be wound is passed between the first cutter 5 and the second cutter 702 and fixed to the winding roller of the winding machine body 1. After the fixing is completed, the winding machine body 1 can be started to wind up the aluminum foil.

[0042] After winding is completed, the electric cylinder 704 is activated. The output shaft of the electric cylinder 704 extends upward and pushes the lifting plate 701 to move upward. During the upward movement of the lifting plate 701, the second cutter 702 and the toothed plate 703 move upward synchronously. When the second cutter 702 rises to the appropriate position, it will cooperate with the first cutter 5 to cut the aluminum foil.

[0043] Meanwhile, as the toothed plate 703 rises, it drives the gear 602 to rotate. As the gear 602 rotates, it drives the rotating frame 603 to rotate synchronously through the transmission shaft 601. The rotating frame 603 drives the pressure roller 604 to rotate. When the aluminum foil is cut, the pressure roller 604 contacts the aluminum foil on the surface of the winding roller of the winding machine body 1 and presses the aluminum foil tightly to prevent the aluminum foil from becoming loose after cutting, which would affect the subsequent transportation of the aluminum foil.

[0044] In summary, this winding device for pharmaceutical cold aluminum production, through the coordinated use of support plate 2, support frame 3, positioning roller 4, first cutter 5, pressing device 6, and cutting device 7, solves the problem that existing tension-controlled winding machines typically lack automatic cutting functionality for aluminum foil. This necessitates manual cutting, which is time-consuming and labor-intensive. Furthermore, the lack of foil pressing during cutting means that if the foil on the winding roller is not pressed promptly after cutting, it may become loose due to loss of tension, requiring manual reassembly and increasing the workload of operators.
