Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical packaging material processing equipment, and in particular, it is a pharmaceutical aluminum foil composite film edge cutting device. Background Technology

[0002] During the production of pharmaceutical aluminum foil composite films, the edges often have irregular or excess portions, requiring edge trimming to ensure dimensional accuracy and appearance quality. Existing edge trimming devices for pharmaceutical aluminum foil composite films can meet basic trimming requirements, but their ability to tighten the film during recycling is weak, resulting in loose winding and poor flatness.

[0003] A search revealed Chinese patent document (authorization announcement number CN215848548U), which discloses a composite film edge-cutting device. The device includes a support frame with a guide roller for guiding the film mounted on it. An edge-cutting mechanism is located on one side of the support frame. The edge-cutting mechanism includes a base fixed to the support frame, with a guide rail mounted on the base; and a cutter seat that slides along the guide rail, with a cutter mounted on the cutter seat. Compared to existing technologies, this device trims the film edges during the roll-out process and controls the roll width, eliminating the need for post-roll trimming and improving production efficiency. This pharmaceutical aluminum foil composite film edge-cutting device can meet basic edge-cutting requirements. However, during recycling, the pharmaceutical aluminum foil composite film has weak tightening ability, resulting in loose winding and poor flatness. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for pharmaceutical aluminum foil composite film to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for pharmaceutical aluminum foil composite film, comprising a support for supporting the cutting process of pharmaceutical aluminum foil composite film, a fixing plate welded to the side of the support, a second motor mounted on the side of the fixing plate, the output shaft of the second motor connected to a take-up roller via a coupling, a bearing mounted on the side of the support, a circular frame and a partition plate welded to the end of the bearing away from the support, a U-shaped hollow column mounted inside the circular frame, a spring disposed inside the U-shaped hollow column, a third moving block connected to one end of the spring, a locking rotating rod movably connected to the side of the third moving block, and limit plates mounted at both ends of the locking rotating rod.

[0006] Preferably, the top of the bearing is provided with a groove, and a guide block is slidably installed inside the groove.

[0007] Preferably, the side of the support is provided with an unwinding roller, and the movable part of the unwinding roller is equipped with a pharmaceutical aluminum foil composite film.

[0008] Preferably, a first motor is mounted on the side of the bracket, and the output shaft of the first motor is connected to a transmission wheel via a coupling. A pressing wheel is meshed with the outer circumference of the transmission wheel.

[0009] Preferably, a fixed guide plate is installed on the side of the bracket, and two rotating shafts are tactilely connected to the side of the fixed guide plate. Two arc-shaped pressure blocks are installed on the outer periphery of one of the rotating shafts, and a pressure rod is installed at one end of the rotating shaft.

[0010] Preferably, an adjustment plate is installed at the bottom of the two arc-shaped pressure blocks, a connecting frame is connected to the side of the adjustment plate, a first rotating column is connected to the side of the connecting frame, a second moving block is slidably connected to one end of the first rotating column, a second rotating column is connected to the top of the second moving block, a first moving block is connected to one end of the second rotating column, and a cutting knife for cutting the pharmaceutical aluminum foil composite film is installed on the side of the first moving block.

[0011] Preferably, the bracket has a bottom dust outlet and a top dust outlet for dust removal connected to both sides.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This pharmaceutical aluminum foil composite film trimming device, thanks to its locking rotating rod structure, increases the amount of pharmaceutical aluminum foil composite film wound on the take-up roller. The pharmaceutical aluminum foil composite film comes into contact with the locking rotating rod, which pulls the spring. Due to the spring's action, the locking rotating rod maintains continuous contact with the edge of the pharmaceutical aluminum foil composite film. The locking rotating rod gradually moves away from the take-up roller. Compared to traditional pharmaceutical aluminum foil composite film trimming devices, which have weak tightening ability during recovery, this structure increases the tightening ability of the pharmaceutical aluminum foil composite film, resulting in tighter winding and improved winding flatness.

[0014] This pharmaceutical aluminum foil composite film edge-cutting device benefits from the structure of the pressing wheel. The first motor drives the pressing wheel on the rotating shaft to rotate, and the pressing wheel drives the pharmaceutical aluminum foil composite film to move. By rotating the arc-shaped pressing block, the arc-shaped pressing block presses down on the adjustment plate. The adjustment plate drives the edge-cutting blade to contact the pharmaceutical aluminum foil composite film, and the edge-cutting blade cuts the film. This structure allows for easy adjustment of the edge-cutting width of the pharmaceutical aluminum foil composite film by adjusting the rotating arc-shaped pressing block.

[0022] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0023] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0024] like Figures 1 to 4The illustrated pharmaceutical aluminum foil composite film trimming device includes a support 1 for supporting the trimming process. A fixing plate 3 is welded to the side of the support 1, and a second motor 301 is mounted on the side of the fixing plate 3. The output shaft of the second motor 301 is connected to a take-up roller 302 via a coupling. A bearing 303 is mounted on the side of the support 1, and a circular frame 306 and a partition plate 5 are welded to the end of the bearing 303 away from the support 1. The trimmed pharmaceutical aluminum foil composite film 401 contacts the take-up roller 302. Due to the action of the partition plate 5, the pharmaceutical aluminum foil composite film 401 is separated from waste. A U-shaped hollow column 307 is installed inside the circular frame 306, and a spring 308 is installed inside the U-shaped hollow column 307. One end of the spring 308 is connected to a third moving block 309, and a locking rotation is movably connected to the side of the third moving block 309. Limiting discs 310 are installed at both ends of the locking rotating rod 311. When the second motor 301 is turned on, it drives the take-up roller 302 to rotate. The trimmed pharmaceutical aluminum foil composite film 401 is collected by the take-up roller 302. After a period of time, the take-up roller 302 wraps more pharmaceutical aluminum foil composite film 401, and the pharmaceutical aluminum foil composite film 401 comes into contact with the locking rotating rod 311. The locking rotating rod 311 pulls the spring 308. Due to the action of the spring 308, the locking rotating rod 311 continues to contact the edge of the pharmaceutical aluminum foil composite film 401. The locking rotating rod 311 slowly moves away from the take-up roller 302. The top of the bearing 303 is provided with a sliding groove 304. A guide block 305 is slidably installed inside the sliding groove 304. Moving the guide block 305 can prevent the trimmed pharmaceutical aluminum foil composite film 401 from shifting.

[0025] A unwinding roller 4 is provided on the side of the support 1. The unwinding roller 4 is a component that holds the pharmaceutical aluminum foil composite film roll. It usually has a certain shaft diameter and length to bear heavy rolls. Its material is generally metal, such as steel or aluminum alloy, to ensure sufficient strength. The two ends of the unwinding roller 4 are mounted on the frame by bearings, allowing the unwinding roller 4 to rotate flexibly and facilitate the smooth unwinding of the composite film. The pharmaceutical aluminum foil composite film 401 is mounted on the movable part of the unwinding roller 4. A first motor 101 is mounted on the side of the support 1. The output shaft of the first motor 101 is connected to a transmission wheel 102 through a coupling. A pressing wheel 103 is meshed with the outer periphery of the transmission wheel 102.

[0026] A fixed guide plate 104 is installed on the side of the bracket 1. Two rotating shafts 105 are rolledly connected to the side of the fixed guide plate 104. The pharmaceutical aluminum foil composite film 401 passes through the underside of the rotating shaft 105. Two arc-shaped pressure blocks 106 are installed on the outer periphery of one of the rotating shafts 105. A pressure rod 6 is installed at one end of the rotating shaft 105.

[0027] An adjustment plate 107 is installed at the bottom of the two arc-shaped pressure blocks 106. A connecting frame 2 is connected to the side of the adjustment plate 107. A first rotating column 201 is connected to the side of the connecting frame 2. A second moving block 205 is slidably connected to one end of the first rotating column 201. A second rotating column 203 is connected to the top of the second moving block 205. A first moving block 202 is connected to one end of the second rotating column 203. A cutting blade 204 for cutting the pharmaceutical aluminum foil composite film is installed on the side of the first moving block 202. The cutting blade 204 is a straight blade. Straight blades are used in some situations where the cutting accuracy is high, and their cutting action is more stable.

[0028] The cutting blade 204 is generally made of high-speed steel or hard alloy. These materials have high hardness, high wear resistance and good toughness, which can ensure the service life and cutting quality of the cutting blade 204. The first motor 101 is turned on, and the first motor 101 drives the pressing wheel 103 on the rotating shaft 105 to rotate. The pressing wheel 103 drives the pharmaceutical aluminum foil composite film 401 to move. By rotating the arc-shaped pressure block 106, the arc-shaped pressure block 106 presses down the adjustment plate 107. The adjustment plate 107 drives the cutting blade 204 to contact the pharmaceutical aluminum foil composite film 401. The cutting blade 204 cuts the pharmaceutical aluminum foil composite film 401. The cut pharmaceutical aluminum foil composite film 401 is driven by the pressing wheel 103 and continues to move towards the take-up roller 302. The two sides of the bracket 1 are respectively connected to the bottom dust outlet 7 and the top dust outlet 701 for dust removal.

[0029] Working principle

[0030] In use, the pharmaceutical aluminum foil composite film trimming device first passes the pharmaceutical aluminum foil composite film 401 under the rotating shaft 105, then turns on the first motor 101. The first motor 101 drives the pressing wheel 103 on the rotating shaft 105 to rotate, and the pressing wheel 103 moves the pharmaceutical aluminum foil composite film 401. By rotating the arc-shaped pressure block 106, the arc-shaped pressure block 106 presses down on the adjusting plate 107. The adjusting plate 107 drives the trimming blade 204 to contact the pharmaceutical aluminum foil composite film 401, and the trimming blade 204 cuts the film. The trimmed pharmaceutical aluminum foil composite film 401 is then driven by the pressing wheel 103 to continuously move towards the take-up roller 302. The composite film 401 comes into contact with the take-up roller 302. Due to the action of the partition 5, the pharmaceutical aluminum foil composite film 401 is separated from the waste. The second motor 301 is turned on, and the second motor 301 drives the take-up roller 302 to rotate. The trimmed pharmaceutical aluminum foil composite film 401 is collected by the take-up roller 302. After a period of time, the amount of pharmaceutical aluminum foil composite film 401 wrapped around the take-up roller 302 increases, and the pharmaceutical aluminum foil composite film 401 comes into contact with the locking rotating rod 311. The locking rotating rod 311 pulls the spring 308. Due to the action of the spring 308, the locking rotating rod 311 continues to contact the edge of the pharmaceutical aluminum foil composite film 401. The locking rotating rod 311 slowly moves away from the take-up roller 302.
