A high-precision slitting device for medicinal aluminum foil

Abstract

The present application relates to the field of aluminum foil processing, especially to a high-precision cutting device for medicinal aluminum foil. The existing cutting device for aluminum foil roll is prone to thermal fatigue of the cutting point, which makes the cutting edge not sharp enough, resulting in poor cutting quality of the latter half of the aluminum foil roll. At the same time, the vibration generated during the cutting of the blade and the aluminum foil roll makes the aluminum foil roll unstable, which further affects the cutting quality of the subsequent aluminum foil roll. A high-precision cutting device for medicinal aluminum foil includes a bottom plate, both sides of which are fixedly connected with support plates, and a blocking rod is fixedly connected between the two support plates. By rotating the center rod and reversing the cutting wheels, the medicinal aluminum foil roll is cut, and the powder generated during the cutting of the medicinal aluminum foil roll is also discharged, thereby improving the cutting quality of the subsequent cutting wheels for the medicinal aluminum foil roll.

Description

Technical Field

[0001] This invention relates to the field of aluminum foil processing, and more particularly to a high-precision slitting device for pharmaceutical aluminum foil. Background Technology

[0002] Aluminum foil is a lightweight, corrosion-resistant, and easily processed metallic material widely used in packaging for the food, pharmaceutical, and electronics industries. Its excellent barrier properties, thermal conductivity, and recyclability make it an important material in the modern packaging industry.

[0003] Existing aluminum foil roll slitting devices typically slit aluminum foil rolls through physical contact with blades. Since the blades are stationary, the cutting point of the blade tends to overheat and experience thermal fatigue after a period of cutting, resulting in a less sharp blade edge and poor slitting quality in the latter half of the aluminum foil roll. Furthermore, the vibration generated during the slitting process can make the aluminum foil roll unstable, further affecting the slitting quality of subsequent aluminum foil rolls. Summary of the Invention

[0004] To overcome the shortcomings of existing aluminum foil roll slitting devices, such as the fixed blade causing thermal fatigue at the cutting point, resulting in insufficient blade sharpness and poor slitting quality in the latter half of the aluminum foil roll, and the vibration generated during slitting, which can make the aluminum foil roll unstable and affect the subsequent slitting quality, this invention provides a high-precision pharmaceutical aluminum foil slitting device that allows the aluminum foil roll and the cutting wheel to rotate in opposite directions, thereby cyclically changing the cutting point between the cutting wheel and the aluminum foil roll, thus improving the slitting quality of the aluminum foil roll by the cutting wheel. Simultaneously, it makes the aluminum foil roll more stable during the slitting process, further improving the slitting quality of the cutting wheel.

[0006] In a preferred embodiment of the present invention, the cutting mechanism includes a cutting frame, the cutting frame is rotatably connected between the two support plates, and torsion springs are connected between the two sides of the support plates that are close to each other and the two cutting frames. A fixed frame is fixedly connected to one side of the cutting frame, a power motor is fixedly connected to the fixed frame, a power shaft is fixedly connected to the output shaft of the power motor, and a plurality of cutting wheels are fixedly connected to the power shaft.

[0007] In a preferred embodiment of the present invention, the internal support mechanism includes a central rod, grooves on both support plates, a central rod placed between the grooves on the two support plates, slots at both ends of the central rod, a fixed ring fixedly connected to one end of the central rod, a limiting ring slidably connected to the other end of the central rod, several locking holes on the other end of the central rod, a screw rotatably connected to the limiting ring, one end of the screw located in one of the locking holes on the central rod, two transverse grooves on the central rod, movable strip seats slidably connected to both ends of the central rod, two movable strips slidably connected to the two transverse grooves of the central rod at both ends, hollow discs rotatably connected to the movable strips, and the two movable strips respectively connected to the central rod. A compression spring is connected between the two sides of the central rod. Two guide rods are fixedly connected to the two transverse grooves of the central rod. Inner support rods are slidably connected to the two transverse grooves of the central rod. The two guide rods are slidably connected to the inner support rods. Four compression springs are connected between the two inner support rods and the two transverse grooves of the central rod. The four compression springs are located on the four guide rods. A support plate is fixedly connected to one of the support plates. A servo motor is fixedly connected to the support plate. The output shaft of the servo motor is engaged with one end of the central rod. Fixed extrusion strips are fixedly connected to both sides of the cutting frame. Two moving plates are slidably connected to the two support plates. Vertical grooves are opened on the four moving plates. A fixed cylinder is fixedly connected to the moving plate near the torsion spring.

[0008] In a preferred embodiment of the invention, the two inner support rods are located within the two transverse grooves of the central rod.

[0009] In a preferred embodiment of the present invention, the limiting mechanism includes a vertical rod, the vertical rod is fixedly connected to each of the four movable plates, two movable slots are opened on each of the two support plates, movable seats are slidably connected to the two movable slots on the two support plates, wedge blocks are fixedly connected to the side of each of the four movable seats near the vertical rod, the wedge blocks are in contact with the vertical rod, and limiting wheels are rotatably connected to each of the four movable seats.

[0010] In a preferred embodiment of the present invention, an extrusion mechanism is further included. The extrusion mechanism is disposed on the two support plates and is used to extrude the pharmaceutical aluminum foil roll. The extrusion mechanism includes a movable slot plate. Two square slots are opened on each of the two support plates. The movable slot plate is slidably connected to the two square slots on the two support plates.

At the same time, the four limiting wheels are rotatably set, which can limit the central rod, and the central rod can also drive the four limiting wheels to rotate when it rotates, thereby reducing the friction between the central rod and the limiting wheels, thereby improving the cutting quality of the pharmaceutical aluminum foil roll.

[0013] 2. The pharmaceutical aluminum foil roll is cut by rotating the central rod in the forward direction and several cutting wheels in the reverse direction. This allows the cutting wheels to discharge the powder generated during the cutting of the pharmaceutical aluminum foil roll, thereby improving the slitting quality of the pharmaceutical aluminum foil roll by the subsequent cutting wheels.

[0014] 3. The movement of the four moving slot plates drives the rotating rod and the extrusion roller to move closer to the pharmaceutical aluminum foil roll. The two extrusion rollers extrude pressure on both sides of the pharmaceutical aluminum foil roll, which makes the subsequent cutting rollers more stable when cutting the pharmaceutical aluminum foil roll, thereby further improving the cutting quality.

[0025] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0026] Example 1: A high-precision cutting device for pharmaceutical aluminum foil, such as... Figures 1-9 As shown, it includes a base plate 1, with support plates 2 welded to both sides of the base plate 1. A stop bar 3 is welded between the two support plates 2. A cutting mechanism is provided between the two support plates 2 for cutting the pharmaceutical aluminum foil roll. An inner support mechanism is also provided between the two support plates 2 for internally supporting the pharmaceutical aluminum foil roll. A limiting mechanism is provided on both support plates 2 for limiting the inner support mechanism.

[0027] The cutting mechanism includes a cutting frame 41, which is rotatably connected between two support plates 2. Torsion springs 42 are connected between the two sides of the support plates 2 that are close to each other and the two cutting frames 41. A fixing frame 43 is welded to one side of the cutting frame 41. A power motor 44 is fixedly connected to the fixing frame 43. A power shaft 45 is fixedly connected to the output shaft of the power motor 44. Several cutting wheels 46 are fixedly connected to the power shaft 45. The several cutting wheels 46 are used to cut the pharmaceutical aluminum foil roll.

[0028] The internal support mechanism includes a central rod 51. Grooves are formed on both support plates 2, and the central rod 51 is placed between the grooves between the two support plates 2. Both ends of the central rod 51 have slots. A fixing ring 52 is welded to one end of the central rod 51, and a limiting ring 53 is slidably connected to the other end of the central rod 51. Several locking holes are formed on the other end of the central rod 51, and a screw 54 is rotatably connected to the limiting ring 53. One end of the screw 54 is located on one of the central rod 51... Within a locking hole, the screw 54 engages with several locking holes on the central rod 51 to limit the movement of the pharmaceutical aluminum foil roll. The central rod 51 has two transverse grooves, and each end of the central rod 51 is slidably connected to a moving strip 55. The ends of each of the two moving strips 55 are slidably connected to the two transverse grooves of the central rod 51. A hollow disc 56 is rotatably connected to each moving strip 55. Compression springs 5 ​​are connected between each of the two moving strips 55 and both sides of the central rod 51. 7. Two guide rods 58 are welded to each of the two transverse slots of the central rod 51. Inner support rods 59 are slidably connected to each of the two transverse slots of the central rod 51. The guide rods 58 guide the inner support rods 59. The two guide rods 58 are slidably connected to the inner support rods 59. Four compression springs 510 are connected between the two inner support rods 59 and the two transverse slots of the central rod 51. The four compression springs 510 are located on the four guide rods 58. One of the support plates 2 is welded with… There is a support plate 511, on which a servo motor 512 is fixedly connected. The output shaft of the servo motor 512 is engaged with one end of the center rod 51. Fixed extrusion strips 513 are welded to both sides of the cutting frame 41. One side of the two fixed extrusion strips 513 is inclined. Two movable plates 514 are slidably connected to the two support plates 2. Vertical grooves are opened on the four movable plates 514. A fixed cylinder 515 is fixedly connected to the movable plate 514 near the torsion spring 42.

[0029] The two inner support rods 59 are located in the two transverse slots of the central rod 51.

[0030] The limiting mechanism includes a vertical rod 61, and the vertical rod 61 is welded to each of the four movable plates 514. Two movable slots are opened on each of the two support plates 2. Movable seats 62 are slidably connected to the two movable slots on the two support plates 2. Wedge blocks 63 are welded to the side of each of the four movable seats 62 near the vertical rod 61. The wedge blocks 63 are in contact with the vertical rod 61. Limiting wheels 64 are rotatably connected to each of the four movable seats 62.

[0031] When pharmaceutical aluminum foil rolls need to be cut, the worker first places the rolls onto the central rod 51, with one side of the roll contacting the fixing ring 52. Then, the limiting ring 53 is fitted onto the central rod 51, and the limiting ring 53 is rotated to adjust its direction so that the screw 54 on the limiting ring 53 aligns with one of the locking holes on the central rod 51. Next, the screw 54 on the limiting ring 53 is rotated, causing it to move downwards and engage with one of the locking holes on the central rod 51. Then, the central rod 51, fixing ring 52, limiting ring 53, screw 54, moving bar 55, hollow disc 56, compression spring 57, guide rod 58, inner support rod 59, and compression spring 510 are placed into the grooves of the two support plates 2, with the central rod 51 close to the servo motor 51. 2. One end of the slot engages with the output shaft of the servo motor 512. Both sides of the two hollow discs 56 are respectively engaged into the vertical slots of the two moving plates 514 on the same side. Then, the worker starts the servo motor 512 and the power motor 44. The output shaft of the servo motor 512 rotates forward, driving the center rod 51, the fixed ring 52, the limit ring 53, the screw 54, the moving bar 55, the compression spring 57, the guide rod 58, the inner support rod 59, and the compression spring 510 to rotate forward together. The output shaft of the power motor 44 rotates in reverse, driving the power shaft 45 and several cutting wheels 46 to rotate in reverse together. Then, the worker pulls the cutting frame 41 to rotate in the direction of the pharmaceutical aluminum foil roll. The torsion spring 42 is twisted. During the rotation of the cutting frame 41 in the direction of the pharmaceutical aluminum foil roll, it drives the two fixed compression bars 513. When they rotate together, the two fixed compression bars 513 compress the two fixed cylinders 515, the two hollow discs 56, and the two moving plates 514 near the torsion spring 42, causing them to move away from each other. The two moving plates 514 near the torsion spring 42, through the hollow discs 56, drive the moving plates 514 away from the torsion spring 42 and the two moving bars 55 to move away from each other. Both compression springs 57 are compressed, and the two moving bars 55, moving away from each other, no longer compress the two inner support rods 59. Under the reset action of the compression spring 510, the two inner support rods 59 reset along the two transverse grooves of the central rod 51, moving away from each other. Through the guide rod 58, the inner support rods 59, and the compression spring 510, they thus exert pressure on the central rod 51. The pharmaceutical aluminum foil roll is opened and clamped from the inside out. The central rod 51 drives the pharmaceutical aluminum foil roll to rotate clockwise. The movement of the four moving plates 514 drives the vertical rods 61 to move. The four vertical rods 61 all press the wedge blocks 63. The two wedge blocks 63 on the same side drive the moving seat 62 and the limiting wheels 64 to move closer to each other. The two limiting wheels 64 on both sides limit the two ends of the central rod 51 respectively. By limiting the two ends of the central rod 51 with the four limiting wheels 64, the central rod 51 can drive the pharmaceutical aluminum foil roll to rotate more stably. At the same time, the rotating setting of the four limiting wheels 64 can limit the central rod 51, and the rotation of the central rod 51 can also drive the four limiting wheels 64 to rotate, thereby reducing the friction between the central rod 51 and the limiting wheels 64.This improves the slitting quality of the pharmaceutical aluminum foil roll. The cutting frame 41 continues to rotate towards the pharmaceutical aluminum foil roll, driving several cutting wheels 46 to contact the pharmaceutical aluminum foil roll. The power shaft 45 and the cutting wheels 46 reverse to cut the pharmaceutical aluminum foil roll. The central rod 51 rotates forward while the cutting wheels 46 reverse, thus cutting the pharmaceutical aluminum foil roll. This allows the cutting wheels 46 to discharge the powder generated during the cutting of the pharmaceutical aluminum foil roll, thereby improving the slitting quality of the subsequent cutting wheels 46. After the pharmaceutical aluminum foil roll is cut, the worker turns off the servo motor 512 and the power motor 44. The output shaft of the servo motor 512 stops rotating and no longer drives the central rod 51 to rotate forward, nor does the central rod drive the pharmaceutical aluminum foil roll to rotate forward. The output shaft of the power motor 44 also stops rotating and no longer drives the power shaft 45 and the cutting wheels 46. Wheel 46 reverses direction, and finally the worker lifts the cutting frame 41. Under the action of the torsion spring 42, the cutting frame 41 resets, causing several cutting wheels 46 and two fixed extrusion bars 513 to reset as well. The cutting wheels 46 reset and disengage from the pharmaceutical aluminum foil roll. The two fixed extrusion bars 513 reset and no longer extrude pressure on the moving plate 514 and the fixed cylinder 515. Under the action of the extrusion spring 57, the moving plate 514 and the fixed cylinder 515 reset, causing two moving bars 55 and two hollow discs 56 to reset. The two moving bars 55 re-extrude pressure on the two inner support rods 59 to reset. Finally, the worker removes the center rod 51, fixed ring 52, limit ring 53, screw 54, moving bars 55, hollow discs 56, extrusion spring 57, guide rod 58, inner support rod 59, and compression spring 510 from the grooves of the two support plates 2. Then, the pharmaceutical aluminum foil roll that has been cut on the center rod 51 can be removed.

[0032] Example 2: Based on Example 1, such as Figure 3 and Figure 4 As shown, it also includes an extrusion mechanism, which is mounted on the two support plates 2. The extrusion mechanism is used to extrude the pharmaceutical aluminum foil roll. The extrusion mechanism includes a movable slot plate 71. Each of the two support plates 2 has two square slots. The movable slot plate 71 is slidably connected to the two square slots on the two support plates 2. Rotating rods 72 are rotatably connected between the movable slots on the same side of the two support plates 2. Each of the four movable slot plates 71 has an inclined slot. Each of the four movable plates 514 has a connecting rod 73 welded on it. The end of the connecting rod 73 away from the movable plate 514 is slidably connected to the inclined slot on the movable slot plate 71. Extrusion wheels 74 are welded on the two rotating rods 72. The two extrusion wheels 74 are used to extrude the pharmaceutical aluminum foil roll. The surfaces of the two extrusion wheels 74 are made of silicone.

[0033] The movement of the four moving plates 514 also drives the four connecting rods 73 to move together. The movement of the four connecting rods 73 pushes the moving plate 71 along the two square slots opened on the two support plates 2 through the inclined grooves on the moving plate 71. The movement of the four moving plates 71 drives the rotating rod 72 and the extrusion wheel 74 to move towards the pharmaceutical aluminum foil roll. The two extrusion wheels 74 extrude pressure on both sides of the pharmaceutical aluminum foil roll, which makes the subsequent cutting wheels 46 more stable when cutting the pharmaceutical aluminum foil roll, thereby further improving the cutting quality. After the cutting is completed, the four moving plates 514 reset, driving the four moving plates 71, the two connecting rods 73 and the two extrusion wheels 74 to reset together.

Therefore, the scope of the invention should be limited only by the appended claims.
