Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical aluminum foil production technology, specifically to a surface degreasing device for pharmaceutical aluminum foil production. Background Technology

[0002] During the production of pharmaceutical aluminum foil, rolling oil, lubricating oil, and other oily impurities inevitably adhere to the surface of the aluminum foil due to rolling and processing. Since pharmaceutical aluminum foil needs to come into direct contact with medicines, its surface cleanliness requirements are extremely stringent. The presence of oil not only affects the bonding strength of subsequent coating, printing, and other processes, but may also pose a potential risk to the quality and safety of medicines due to oil migration. Therefore, surface degreasing is a crucial pretreatment step in the pharmaceutical aluminum foil production process.

[0003] According to announcement number CN217250902U, a surface degreasing device for pharmaceutical aluminum foil production is disclosed. It includes a moving mechanism for moving the device, a support mechanism for supporting the upper equipment, and a lifting mechanism for adjusting the overall height of the device. The support mechanism is installed on both sides of the moving mechanism, and the lifting mechanism is installed above the moving mechanism. It also includes a heating mechanism for heating grease adhering to the aluminum foil surface and a degreasing mechanism for removing grease from the aluminum foil surface. The heating mechanism is installed on the lifting mechanism, and the degreasing mechanism is located on one side of the heating mechanism. This invention, by setting up a degreasing mechanism, utilizes an oil-absorbing layer made of sponge to absorb grease from the aluminum foil surface, achieving a degreasing effect superior to ordinary degreasing rollers. It is also equipped with two sets of oil-absorbing layers; when one set needs to be replaced, the other set can be activated, thus allowing for uninterrupted degreasing.

[0005] However, during use, due to the lack of a limiting structure, the aluminum foil may deviate during the conveying process due to the airflow from the heating mechanism and the friction of the oil-absorbing layer, resulting in wrinkles at the edge of the aluminum foil or deviation from the degreasing area, affecting the accuracy of subsequent coating, printing and other processes, and even causing the aluminum foil to be scrapped.

[0028] Example 1

[0029] Reference Figure 1-3This is the first embodiment of the present invention, providing a surface degreasing device for the production of pharmaceutical aluminum foil, including a degreasing device 1. The degreasing device 1 includes a movable support mechanism 11, a lifting frame 12, a heating box 13, an air supply pipe 14, a fixed frame 15, and a nozzle 16. The lifting frame 12 is fixedly installed on the top of the movable support mechanism 11, the heating box 13 is fixedly installed on the top of the lifting frame 12, the air supply pipe 14 is located on the left side of the top of the lifting frame 12, the fixed frame 15 is fixedly connected to the rear side of the inner wall of the lifting frame 12, one end of the air supply pipe 14 is connected to the left side of the heating box 13, and the other end of the air supply pipe 14 is connected to the top of the fixed frame 15. The nozzle 16 is fixedly connected to the top and bottom of both sides of the fixed frame 15.

[0030] Limiting mechanism 2; The limiting mechanism 2 includes a rectangular frame 21, which is disposed on the front and rear sides of both sides of the fixed frame 15. The top and bottom of the inner wall of the rectangular frame 21 are movably connected to limiting rollers 22 through bearings. A moving component 23 is fixedly connected to the bottom of the fixed frame 15, and a driving component 24 is disposed on the front side of the bottom of the fixed frame 15.

[0031] Guide mechanism 3; guide mechanism 3 is opened on the top of both sides of fixed frame 15; movable component 23 movable frame 231, movable frame 231 is fixedly connected to the bottom of fixed frame 15; movable blocks 232 are movably connected to the front and rear sides of the inner wall of movable frame 231; the top of movable block 232 is fixedly connected to the bottom of rectangular frame 21; drive component 24 includes forward and reverse motor 241, forward and reverse motor 241 is set on the front side of the bottom of fixed frame 15, forward and reverse motor 241 is fixedly connected to the front side of movable frame 231; forward and reverse motor The output end of 241 is fixedly connected to a bidirectional lead screw 242. The surface of the moving block 232 is provided with a threaded hole 243. Both sides of the surface of the bidirectional lead screw 242 are threadedly connected to the inner wall of the threaded hole 243. The front side of the fixed frame 15 is fixedly installed with a control panel 4. The control panel 4 is electrically connected to the forward and reverse motor 241 through wires. The top and bottom sides of the inner wall of the movable frame 231 are provided with sliding grooves 5. The top and bottom sides of the moving block 232 are movably embedded with balls 6. The surface of the balls 6 is movably connected to the inner wall of the sliding groove 5.

[0032] Specifically, the limiting mechanism 2 can effectively constrain the pharmaceutical aluminum foil during the conveying process, preventing it from shifting position due to the aforementioned external forces during the degreasing stage. This ensures that the aluminum foil remains stably within the degreasing area, guaranteeing a uniform and thorough degreasing process, reducing the problem of substandard degreasing caused by shifting, and thus avoiding the adverse effects of oil residue on subsequent coating and printing processes.

[0033] Furthermore, when it is necessary to limit the aluminum foil, the user sends a start command to the forward and reverse motor 241 through the control panel 4 on the front side of the fixed frame 15 according to the width of the aluminum foil, and sets the adjustment direction of the forward and reverse motor 241. After the forward and reverse motor 241 is started, its output end drives the bidirectional lead screw 242 to rotate synchronously. By using the two sets of threads with opposite directions on the surface of the lead screw to rotate in the threaded hole 243, it can generate a driving force on the two moving blocks 232 in opposite directions, so that the moving blocks 232 move horizontally in the movable frame 231. At this time, the ball bearings 6 at the top and bottom of the moving blocks 232 move in the movable frame 231. The aluminum foil rolls within the chute 5, converting sliding friction into rolling friction, reducing resistance. Simultaneously, it drives the top rectangular frame 21 to move synchronously, adjusting the limiting roller 22 to a position that contacts both sides of the aluminum foil. This ensures that the spacing between the limiting rollers 22 precisely matches the width of the aluminum foil. The aluminum foil passes between the upper and lower limiting rollers 22 of the rectangular frames 21 on both sides. If there is a tendency to deviate due to external force during the conveying process, it will contact the limiting roller 22. The limiting roller 22 rotates synchronously with the aluminum foil through bearings. Without damaging the surface of the aluminum foil, it physically blocks the aluminum foil within the preset conveying path, preventing edge wrinkles or deviation from the degreasing area.

[0034] Example 2

[0035] In the second embodiment of this utility model, the guiding mechanism 3 includes a guide groove 31, which is opened on the top of both sides of the fixed frame 15. A guide block 32 is movably connected to the inner wall of the guide groove 31. The bottom of the guide block 32 is fixedly connected to the top of the rectangular frame 21. A measuring component 33 is fixedly connected to the inner side of the guide block 32. The measuring component 33 includes a pointer 331, which is fixedly connected to the inner side of the guide block 32. A scale groove 332 is opened on the top of both sides of the fixed frame 15. The scale grooves 332 are arranged in several groups and are evenly distributed. The pointer 331 is located on the outer side of the scale groove 332.

[0036] Specifically, the guide mechanism 3 can assist the limiting mechanism 2 in better exerting the limiting effect, reducing the shaking and deviation of the aluminum foil during the conveying process, ensuring that the oil removal airflow or oil removal medium sprayed by the nozzle 16 can accurately act on the surface of the aluminum foil, and improving the oil removal effect.

[0037] Furthermore, when the limiting roller 22 and the rectangular frame 21 move horizontally, the guide block 32 moves synchronously with the rectangular frame 21 and slides along the inner wall of the guide groove 31. The sliding process of the guide block 32 can guide the movement of the rectangular frame 21 and can cooperate with the moving block 232 at the bottom of the rectangular frame 21 to form an upper and lower double guide structure, effectively preventing the rectangular frame 21 from tilting or deviating vertically during the movement, ensuring that the rectangular frame 21 always maintains a horizontal and stable movement state, and avoiding the limiting roller 22 from deviating and shaking. At the same time, the pointer 331 fixedly connected to the inner side of the guide block 32 moves synchronously with the guide block 32. The pointer 331 cooperates with the scale groove 332 on the fixed frame 15, providing the operator with an intuitive adjustment reference and further ensuring the accuracy of the spacing adjustment.

[0038] Working principle:

[0039] First, the hot air generated by the heating chamber 13 enters the fixed frame 15 through the air supply pipe 14. Then, hot air is sprayed onto the surface of the conveying aluminum foil through the nozzles 16 on the top and bottom sides of the fixed frame 15. The hot air directly acts on the oil stains on the surface of the aluminum foil, causing the oil stains to soften and the viscosity to decrease. During the degreasing process, the user starts the forward and reverse motor 241 through the control panel 4 on the front side of the fixed frame 15 according to the width of the aluminum foil being produced. The output end of the forward and reverse motor 241 drives the bidirectional lead screw 242 to rotate synchronously. The surface of the bidirectional lead screw 242 is machined with threads of opposite left and right helix directions and is connected to the surface of the moving block 232. The threaded hole 243 engages precisely. When the lead screw rotates, it generates opposing or opposite driving forces on the two moving blocks 232. Under the driving force of the bidirectional lead screw 242, the moving blocks 232 slide horizontally along the movable frame 231, simultaneously driving the rectangular frame 21 to move synchronously. During this process, to reduce moving friction and avoid jamming, ball bearings 6 are movably embedded on both sides of the top and bottom of the moving blocks 232. The ball bearings 6 roll in the grooves 5 at the top and bottom of the inner wall of the movable frame 231, converting sliding friction into rolling friction, ensuring that the rectangular frame 21 moves smoothly and without deviation. To prevent the rectangular frame 21 from slipping during movement... Currently tilted vertically, the bottom of guide block 32 is fixedly connected to the top of rectangular frame 21. When rectangular frame 21 moves with moving block 232, guide block 32 slides synchronously along guide groove 31, forming a double guide structure with the bottom movable frame 231 and moving block 232, ensuring that rectangular frame 21 always moves horizontally. At the same time, pointer 331 on the inner side of guide block 32 moves with guide block 32. The operator can visually confirm the distance between the two rectangular frames 21 by the direction of pointer 331 on the scale groove 332, ensuring that the distance between limit rollers 22 is completely matched with the width of aluminum foil, and avoiding excessive distance from causing limit. If the aluminum foil is damaged or the spacing is too small, it will be squeezed. After the spacing of the rectangular frame 21 is adjusted, the aluminum foil passes between the limiting rollers 22 on the inner wall of the two rectangular frames 21. During the aluminum foil conveying process, if the hot air jet from the nozzle 16 causes a deviation due to the impact force and the subsequent oil absorption friction, the edge of the aluminum foil will come into contact with the limiting roller 22. Since the limiting roller 22 can rotate synchronously with the movement of the aluminum foil, it avoids scratching the surface of the aluminum foil and can also limit the aluminum foil to the preset conveying path through physical blocking, preventing the edge of the aluminum foil from wrinkling or deviating from the nozzle 16, and ensuring the uniformity of oil removal and the accuracy of subsequent coating and printing processes.

[0040] In summary, by setting up the limiting mechanism 2 and the guiding mechanism 3, the limiting mechanism 2 can accurately limit the movement of the pharmaceutical aluminum foil during transportation. At the same time, the guiding mechanism 3 can assist the limiting mechanism 2 in better performing its limiting effect, reducing the shaking and deviation of the aluminum foil during transportation. This solves the problem that, due to the lack of a limiting structure, the aluminum foil may deviate during transportation due to the airflow from the heating mechanism and the friction of the oil-absorbing layer, resulting in wrinkles at the edge of the aluminum foil or deviation from the degreasing area, affecting the accuracy of subsequent coating, printing and other processes, and even causing the aluminum foil to be scrapped. Thus, the limiting function is achieved.
