Description

Technical Field

[0001] This utility model relates to the field of self-sealing bag processing technology, specifically a slitting machine for processing pharmaceutical self-sealing bags. Background Technology

[0002] Self-sealing bags are a common type of packaging for pharmaceuticals. During production, they need to be cut for subsequent processing. A search revealed a Chinese patent publication number CN201721223530.8, which discloses a cutting device for processing self-sealing bags. Although this device improves the elastic pushing effect of multiple connecting plates on the cutter by setting multiple sets of first springs, reducing the damage caused by excessive force on the cutter and improving the protection effect of the cutter, the device can still cause significant wear to the cutting blade when the spring pressure is too high. When the spring pressure is too low, the cutter may not be able to completely cut the self-sealing bag. The elasticity of the spring that pushes the cutter cannot be adjusted according to actual use, reducing the adjustability of the device. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a slitting machine for processing pharmaceutical self-sealing bags, which solves the problem mentioned in the background art that the elasticity of the spring that drives the cutter in existing devices cannot be adjusted according to actual use, thus reducing the adjustability of the device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a slitting machine for processing pharmaceutical self-sealing bags, comprising;

[0005] The base is used to support the entire slitting machine.

[0006] Also includes;

[0007] The gantry frame is bolted to the top of the base.

[0008] The slitting mechanism, installed inside the gantry, is used to cut self-sealing bags using adaptive pressure.

[0009] Feeding mechanism; it is mounted on the top surface of the base and is used to convey self-sealing bags to the area below the slitting mechanism;

[0010] Grinding mechanism; located on one side of the gantry frame, used to automatically grind the slitting mechanism.

[0011] Preferably, the cutting mechanism includes a lifting cylinder. One end of the lifting cylinder is embedded in the top of the gantry frame. A lifting rod is fitted on the outside of the bottom telescopic end of the lifting cylinder. The inside of the lifting rod slides in contact with the outer wall of the slide rod. One bottom end of the slide rod is welded to the top of the mounting plate. Both ends of the mounting plate are welded to the bottom of the threaded rod. The threaded rod slides in contact with both ends of the lifting rod. A cutting blade is welded to the bottom of the mounting plate. Under the push of the lifting cylinder, the lifting rod can move downward. While the lifting rod moves downward, it can press down on the first spring, which in turn can elastically push the cutting blade downward, so that the cutting blade can cut the self-sealing bag below. At the same time, the first spring can reduce the wear of the cutting blade.

[0012] Preferably, there are two threaded rods, and the outer walls of the two threaded rods are threadedly connected to the inner side of the knob. The knob is located at the bottom end of the first spring. By rotating the knob, the knob can move upward. When the knob moves upward, it will compress the first spring, thereby increasing the elasticity of the first spring and thus adjusting the elastic pressure applied to the cutting blade.

[0013] Preferably, the feeding mechanism includes two linear slide rails. The top of the linear slide rail is slidably connected to an electric slider, and the top of the electric slider is connected to one end of the bottom of the moving frame. A micro cylinder is installed in the middle of the moving frame by screws. A micro air pump is installed at the bottom telescopic end of the micro cylinder. Suction cups are provided on both sides of the micro air pump. The suction cups are connected to the micro cylinder through hoses. By placing the self-sealing bag at one end of the base, the electric slider drives the suction cup to move. The micro cylinder pushes the suction cup downward, thereby adsorbing the self-sealing bag and moving it below the cutting blade.

[0014] Preferably, the grinding mechanism includes a fixed frame, the bottom ends of the fixed frame are connected to the base by bolts, a connecting plate is welded to one side of the fixed frame, and one side of the connecting plate is rotatably connected to one top end of the grinding block. By setting a grinding block on one side of the cutting blade, under the push of the second spring, the inclined surface of one side of the grinding block can be pushed to fit against the cutting blade. While the cutting blade moves downward, it can rub against the inclined surface of the grinding block, thereby grinding the cutting blade through the surface of the grinding block.

[0015] Preferably, a second spring is provided between the grinding block and the connecting plate. One side of the grinding block has a sloping structure. The second spring helps the grinding block to make elastic contact with the cutting blade, so that when the cutting blade continues to move downward, the grinding block can automatically move to one side to avoid interfering with the downward movement of the cutting blade. The grinding block always maintains contact with the cutting blade.

[0016] It is worth noting that the entire device is controlled via a master control button connected to an external device. Since the device matched with the control button is a common device and belongs to existing common technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0017] This utility model provides a slitting machine for processing pharmaceutical self-sealing bags. It has the following beneficial effects:

[0018] (1) The pharmaceutical self-sealing bag slitting machine involves placing the self-sealing bag at one end of the base; then, the electric slider drives the suction cup to move, adsorb the self-sealing bag and guide it to the underside of the cutting blade; under the push of the lifting cylinder, the lifting rod moves downward, while pressing the first spring, so that the first spring elastically pushes the cutting blade downward to cut the self-sealing bag; the design of the first spring effectively reduces the wear of the cutting blade; by rotating the knob, the knob moves upward, compressing the first spring and increasing its elasticity, thereby adjusting the elastic pressure on the cutting blade, so that the first spring can be adjusted to a suitable pressure, improving the adjustability of the device; this not only helps to protect the cutting blade, but also ensures the accurate slitting of the self-sealing bag.

[0019] (2) The slitting machine for processing pharmaceutical self-sealing bags has a grinding block on one side of the cutting blade. Under the push of the second spring, the inclined surface of the grinding block on one side can be pushed to fit with the cutting blade. While the cutting blade moves downward, it can rub against the inclined surface of the grinding block, and then the blade can be polished by the surface of the grinding block. The cutting blade is continuously polished by the grinding block while moving up and down, so that the cutting blade can remain sharp and extend the service life of the cutting blade.

[0020] This solves the problem that the spring elasticity of the existing device that drives the cutter cannot be adjusted according to actual use, thus reducing the adjustability of the device. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] Please see Figure 1-5This utility model provides a technical solution: a slitting machine for processing pharmaceutical self-sealing bags, comprising: a base 1, which supports the entire slitting machine; a gantry frame 2, which is bolted to the top of the base 1; a slitting mechanism 3, which is installed inside the gantry frame 2 and is used to cut the self-sealing bags under adaptive pressure; a feeding mechanism 4, which is installed on the top surface of the base 1 and is used to transport the self-sealing bags to the area below the slitting mechanism 3; and a grinding mechanism 5, which is located on one side of the gantry frame 2 and is used to automatically grind the slitting mechanism 3. The slitting mechanism 3 includes a lifting cylinder 301, one end of which is embedded in the top of the gantry frame 2, and the bottom of the lifting cylinder 301 extends outwards. The outer end of the constricted end is fitted with a lifting rod 302. The inside of the lifting rod 302 slides in contact with the outer wall of the slide rod 303. One bottom end of the slide rod 303 is welded to the top of the mounting plate 305. Both ends of the mounting plate 305 are welded to the bottom of the threaded rod 304. The threaded rod 304 slides in contact with both ends of the lifting rod 302. A cutting blade 306 is welded to the bottom of the mounting plate 305. There are two threaded rods 304. The outer walls of the two threaded rods 304 are threadedly connected to the inner side of the knob 308. The knob 308 is located at the bottom end of the first spring 307. The feeding mechanism 4 includes a linear slide rail 401. There are two linear slide rails 401. The top of the linear slide rail 401 is slidably connected to the electric slider 402. The top of the 02 is connected to one end of the bottom of the mobile frame 403. A miniature cylinder 404 is installed in the middle of the mobile frame 403 by screws. A miniature air pump 405 is installed at the telescopic end of the bottom of the miniature air pump 404. Suction cups 406 are provided on both sides of the miniature air pump 405. The suction cups 406 are connected to the miniature cylinder 404 through hoses. When using this device, the self-sealing bag is placed at one end of the top of the base 1, and then the electric slider 402 drives the suction cups 406 to move, so that the suction cups 406 can pick up the self-sealing bag and move it below the cutting blade 306. Under the push of the lifting cylinder 301, the lifting rod 302 can move downward, and the lifting rod 302 can press downward at the same time. The first spring 307, in turn, elastically pushes the cutting blade 306 downwards, enabling the cutting blade 306 to cut the self-sealing bag below. Simultaneously, the first spring 307 reduces wear on the cutting blade 306. By rotating the knob 308, the knob 308 can move upwards, compressing the first spring 307 and increasing its elasticity. This allows adjustment of the elastic pressure applied to the cutting blade 306, ensuring the first spring 307 reaches a suitable pressure. This improves the adjustability of the device, protecting the cutting blade 306 while ensuring the self-sealing bag can be cut.

[0030] Example 2:

[0031] A slitting machine for processing pharmaceutical self-sealing bags includes a grinding mechanism 5 comprising a fixed frame 501. The bottom ends of the fixed frame 501 are connected to a base 1 by bolts. A connecting plate 502 is welded to one side of the fixed frame 501. One side of the connecting plate 502 is rotatably connected to one top end of a grinding block 504. A second spring 503 is provided between the grinding block 504 and the connecting plate 502. One side of the grinding block 504 has a sloping structure. By providing the grinding block 504 on one side of a cutting blade 306, the second spring 503 pushes the sloping surface of the grinding block 504 to engage with the blade of the cutting blade 306. As the cutting blade 306 moves downward, it rubs against the inclined surface of the grinding block 504, thereby sharpening the blade through the surface of the grinding block 504. This continuous sharpening of the blade by the grinding block 504 during the reciprocating movement of the cutting blade 306 keeps it sharp and extends its service life. The second spring 503 facilitates elastic contact between the grinding block 504 and the cutting blade 306, allowing the grinding block 504 to automatically move to one side to avoid interfering with the downward movement of the cutting blade 306.

[0032] Working principle: During operation, the self-sealing bag is first placed on the top of one end of the base 1. Then, the electric slider 402 drives the suction cup 406 to move along a predetermined path, adsorbing the self-sealing bag and guiding it below the cutting blade 306. Under the pushing action of the lifting cylinder 301, the lifting rod 302 moves downward, simultaneously applying pressure to the first spring 307, causing it to elastically push the cutting blade 306 downward, thus cutting the self-sealing bag. The design of the first spring 307 helps reduce the wear of the cutting blade 306. By rotating the knob 308, the vertical position of the knob 308 can be adjusted, thereby changing the position of the first spring 307. The compression amount is adjusted to regulate the elastic pressure to adapt to different cutting needs, improving the device's adjustment flexibility and ensuring the protection of the cutting blade 306 and the precise cutting of self-sealing bags. Furthermore, the device is equipped with a grinding block 504 on one side of the cutting blade 306, pushed by a second spring 503, so that the inclined surface of the grinding block 504 is in close contact with the cutting blade 306. When the cutting blade 306 moves downwards, its blade rubs against the inclined surface of the grinding block 504, achieving a grinding effect on the blade. This design ensures that the cutting blade 306 is continuously ground during reciprocating motion, maintaining the sharpness of the blade and thus extending the service life of the cutting blade 306.
