Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pharmaceutical aluminum foil processing technology, and in particular relates to a shearing device for pharmaceutical aluminum foil processing. Background Technology
[0002] Pharmaceutical aluminum foil has become an indispensable choice for modern pharmaceutical packaging due to its excellent physical and chemical properties, outstanding packaging performance, environmental friendliness, and economy. With increasing market demand and technological advancements, the application prospects of pharmaceutical aluminum foil bags are broad.
[0003] The problem with the above technology is that before aluminum foil is used for pharmaceutical packaging, it needs to be cut to make it the right size. However, during the cutting process, the smoothness of the aluminum foil itself can easily cause deviation, which makes the aluminum foil irregular after it is cut out. Utility Model Content
[0004] In view of the problems existing in the prior art, the present invention provides a shearing device for processing pharmaceutical aluminum foil that can overcome or at least partially solve the above problems.
[0005] This utility model is implemented as follows: a shearing device for processing pharmaceutical aluminum foil includes a base, a first support plate, a second support plate, a third support plate, and a fourth support plate. The first, second, third, and fourth support plates are all fixedly connected to the top of the base. A moving mechanism is provided on the top of the base. An anti-deviation mechanism is provided on one side of the second support plate. A fixing mechanism is provided on the top of the moving mechanism. A feeding roller is rotatably connected to one side of the first support plate via a rotating shaft. A first motor is fixedly connected to the front side of both the third and fourth support plates. The output end of the first motor on the left side passes through the front fourth support plate and is fixedly connected to a winding roller. The rear end of the winding roller is rotatably connected to the rear fourth support plate via a rotating shaft.
[0006] To restrict the aluminum foil during the cutting process, preferably, the anti-deviation mechanism includes a fixed plate fixedly connected to one side of the second support plate and an anti-deviation roller rotatably connected to one side of the second support plate via a rotating shaft. A connecting rod is slidably connected to the inner wall of the fixed plate. The bottom of the connecting rod passes through the fixed plate and extends downward. A pressure roller is rotatably connected to the inner wall of the connecting rod via a rotating shaft. A ring is fixedly sleeved on the surface of the connecting rod. A spring is fixedly connected to the top of the ring. The top of the spring is fixedly connected to the fixed plate. The circumferential side of the pressure roller contacts the surface of the anti-deviation roller. The aluminum foil passes between the pressure roller and the anti-deviation roller. The pressure roller presses on the upper surface of the aluminum foil through the spring. The cooperation between the pressure roller and the anti-deviation roller can effectively prevent the aluminum foil from shifting to the front or back sides, and the pressure roller will not obstruct the movement of the aluminum foil towards the cutting wheel.
[0007] To prevent workers from manually pulling the aluminum foil and getting injured when it passes the cutting wheel, the fixing mechanism preferably includes a connecting plate. A bolt is threaded onto the inner wall of the connecting plate, and the bottom of the bolt passes through the top of the connecting plate and is rotatably connected to a pressure plate via a bearing. One side of the pressure plate is slidably connected to the inner side of the connecting plate via a slider and a groove. A pressure block is fixedly connected to the inner side of the connecting plate. Both the pressure plate and the pressure wheel are made of rubber. After the aluminum foil passes between the pressure wheel and the anti-deviation roller, one end of the aluminum foil is placed on top of the pressure block. The bolt is then tightened to lower the pressure block and fix the aluminum foil. The fixing mechanism is then moved by a moving mechanism, allowing the aluminum foil to pass through the cutting wheel and reach the winding roller.
[0008] To provide a stable traction force for the aluminum foil, preferably, the moving mechanism includes a second motor fixedly connected to one side of the base. A lead screw is fixedly connected to the output end on the right side of the second motor. A moving plate is sleeved on the surface of the lead screw. The inner wall of the moving plate is threadedly connected to the surface of the lead screw. The top of the moving plate is fixedly connected to a connecting plate. By starting the second motor to rotate forward or in reverse, the second motor drives the lead screw to rotate. The lead screw drives the moving plate to move left and right. The moving plate drives the fixing mechanism to move. The fixing mechanism drives the aluminum foil to move, which can make the aluminum foil move stably.
[0009] In order to cut the aluminum foil, preferably, the output end of the first motor on the right side passes through the third support plate on the front side and is fixedly connected to a rotating rod. The rear end of the rotating rod is rotatably connected to the third support plate on the rear side through a rotating shaft. A cutting wheel is fixedly sleeved on the surface of the rotating rod. When the first motor on the right side is started, the first motor on the right side drives the cutting wheel to rotate through the rotating rod to cut the aluminum foil.
[0010] To ensure stability during movement of the movable plate, preferably, a slide rail is slidably connected to the inner wall of the movable plate, and the bottom of the slide rail is fixedly connected to the base. The slide rail limits the movement of the movable plate, making it more stable during movement.
[0011] To support the lead screw, preferably, the end of the lead screw away from the second motor is rotatably connected to a support block via a bearing. The bottom of the support block is fixedly connected to the base. The support block supports the lead screw, ensuring its stability.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention, by setting an anti-deviation mechanism, allows the aluminum foil to pass between the pressure roller and the anti-deviation roller. The pressure roller is pressed against the upper surface of the aluminum foil by a spring. The cooperation between the pressure roller and the anti-deviation roller can effectively prevent the aluminum foil from shifting to the front or back sides. The pressure roller will not obstruct the movement of the aluminum foil towards the cutting roller. This solves the problem that during the aluminum foil cutting process, the smoothness of the aluminum foil itself can easily cause deviation, which makes the aluminum foil uneven after being cut.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0021] like Figures 1 to 4As shown in the figure, a shearing device for processing pharmaceutical aluminum foil provided in this embodiment of the present invention includes a base 1, a first support plate 1a, a second support plate 2, a third support plate 3, and a fourth support plate 4. The first support plate 1a, the second support plate 2, the third support plate 3, and the fourth support plate 4 are all fixedly connected to the top of the base 1. A moving mechanism 12 is provided on the top of the base 1. An anti-deviation mechanism 10 is provided on one side of the second support plate 2. A fixing mechanism 11 is provided on the top of the moving mechanism 12. A feeding roller 5 is rotatably connected to one side of the first support plate 1a through a rotating shaft. A first motor 9 is fixedly connected to the front side of both the third support plate 3 and the fourth support plate 4. The output end of the left first motor 9 passes through the front fourth support plate 4 and is fixedly connected to a winding roller 6. The rear end of the winding roller 6 is rotatably connected to the rear fourth support plate 4 through a rotating shaft.
[0022] To restrict the aluminum foil during the cutting process, the anti-deviation mechanism 10 includes a fixed plate 101 fixedly connected to one side of the second support plate 2 and an anti-deviation roller 102 rotatably connected to one side of the second support plate 2 via a rotating shaft. A connecting rod 103 is slidably connected to the inner wall of the fixed plate 101. The bottom of the connecting rod 103 passes through the fixed plate 101 and extends downward. A pressure roller 106 is rotatably connected to the inner wall of the connecting rod 103 via a rotating shaft. A ring 105 is fixedly sleeved on the surface of the connecting rod 103. A spring 104 is fixedly connected to the top of 105. The top of the spring 104 is fixedly connected to the fixed plate 101. The circumferential side of the pressure roller 106 contacts the surface of the anti-deviation roller 102, and the aluminum foil passes through the pressure roller 106 and the anti-deviation roller 102. The pressure roller 106 is pressed on the upper surface of the aluminum foil by the spring 104. The cooperation between the pressure roller 106 and the anti-deviation roller 102 can effectively prevent the aluminum foil from shifting to the front and back sides. The pressure roller 106 will not hinder the aluminum foil from moving towards the cutting roller 8.
[0023] To prevent workers from manually pulling the aluminum foil and getting injured when it passes the cutting wheel 8, the fixing mechanism 11 includes a connecting plate 111. The inner wall of the connecting plate 111 is threaded with a bolt 112. The bottom of the bolt 112 passes through the top of the connecting plate 111 and is rotatably connected to a pressure plate 113 via a bearing. One side of the pressure plate 113 is slidably connected to the inner side of the connecting plate 111 via a slider and a groove. A pressure block 114 is fixedly connected to the inner side of the connecting plate 111. Both the pressure plate 113 and the pressure wheel 106 are made of rubber. After the aluminum foil passes between the pressure wheel 106 and the anti-deviation roller 102, one end of the aluminum foil is placed on the top of the pressure block 114. Then, the bolt 112 is turned to lower the pressure block and fix the aluminum foil. Then, the fixing mechanism 11 is moved by the moving mechanism 12 so that the aluminum foil passes through the cutting wheel 8 and reaches the winding roller 6.
[0024] To provide a stable traction force for the aluminum foil, the moving mechanism 12 includes a second motor 121 fixedly connected to one side of the base 1. A lead screw 122 is fixedly connected to the output end on the right side of the second motor 121. A moving plate 123 is sleeved on the surface of the lead screw 122. The inner wall of the moving plate 123 is threadedly connected to the surface of the lead screw 122. The top of the moving plate 123 is fixedly connected to the connecting plate 111. By starting the second motor 121 to start forward or reverse rotation, the second motor 121 drives the lead screw 122 to rotate. The lead screw 122 drives the moving plate 123 to move left and right. The moving plate 123 drives the fixing mechanism 11 to move. The fixing mechanism 11 drives the aluminum foil to move, which can make the aluminum foil move stably.
[0025] In order to cut the aluminum foil, the output end of the right first motor 9 passes through the front third support plate 3 and is fixedly connected to the rotating rod 7. The rear end of the rotating rod 7 is rotatably connected to the rear third support plate 3 through a rotating shaft. The surface of the rotating rod 7 is fixedly fitted with a cutting wheel 8. When the right first motor 9 is started, the right first motor 9 drives the cutting wheel 8 to rotate through the rotating rod 7 to cut the aluminum foil.
[0026] To ensure the stability of the moving plate 123 during movement, a slide rail 13 is slidably connected to the inner wall of the moving plate 123. The bottom of the slide rail 13 is fixedly connected to the base 1. The slide rail 13 limits the movement of the moving plate 123, making the moving plate 123 more stable during movement.
[0027] To support the lead screw 122, a support block 14 is rotatably connected to the end of the lead screw 122 away from the second motor 121 via a bearing. The bottom of the support block 14 is fixedly connected to the base 1. The support block 14 supports the lead screw 122, ensuring the stability of the lead screw 122.
[0028] The working principle of this utility model:
[0029] In use, the first motor 9 and the second motor 121 are connected to a controller with an external PLC control module. Then, the aluminum foil on the feeding roller 5 is passed between the pressure roller 106 and the anti-deviation roller 102. The pressure roller 106 is pressed against the upper surface of the aluminum foil by the spring 104. The cooperation between the pressure roller 106 and the anti-deviation roller 102 effectively prevents the aluminum foil from shifting forward or backward. The pressure roller 106 also does not obstruct the movement of the aluminum foil towards the cutting roller 8. After passing the aluminum foil between the pressure roller 106 and the anti-deviation roller 102, one end of the aluminum foil is placed on top of the pressure block 114. Then, the bolt 112 is tightened to lower the pressure block and fix the aluminum foil. Then, the moving mechanism 12 drives the fixed mechanism 11 to move, and the right first motor 9 is started. The right first motor 9 drives the cutting wheel 8 to rotate through the rotating rod 7 to cut the aluminum foil. At this time, the second motor 121 is started to rotate forward or backward. The second motor 121 drives the lead screw 122 to rotate. The lead screw 122 drives the moving plate 123 to move left and right. The moving plate 123 drives the fixed mechanism 11 to move. The fixed mechanism 11 drives the aluminum foil to move, which can make the aluminum foil move stably. After the aluminum foil passes through the cutting wheel 8, it reaches the winding roller 6 and is connected to the winding roller. At this time, the left first motor 9 is started again, and the winding roller rotates to wind up the cut aluminum foil.
