Description

Technical Field

[0001] The present invention relates to the technical field of scalpel packaging, in particular to an automatic packaging machine for scalpels. Background Art

[0002] Surgical blades are a commonly used medical product. Due to their large usage, they are generally purchased in large quantities, which involves the problem of long-term storage. Because they are medical supplies, they also involve hygiene issues. Therefore, the packaging requirements for surgical blades are relatively high.

[0003] In the prior art, when packaging surgical blades, the surgical blades are generally attached to the rust-proof paper through the upper and lower films of the packaging bag for packaging, and then they are heat-pressed and edge-sealed for packaging, and finally they are cut into individual surgical blades for sorting and collection, thus forming an automatic packaging production line for surgical blades. However, in the process of placing the surgical blades on the rust-proof paper, a hook is generally used to hook the hollowed-out position of the surgical blade to remove it from the loading position, and then the hook is separated from the surgical blade, causing the surgical blade to fall on the rust-proof paper on the lower film of the packaging bag under the action of its own gravity. Since the surgical blades will deviate from the rust-proof paper when falling by themselves, and the deviation of the deviated surgical blades cannot be corrected during the self-operation of the production line, and the packaging bag cannot be partially flattened during the deviation correction process, the deviated surgical blades are easily compressed during the subsequent hot-pressing and packaging, and the quality of the hot-pressing and packaging of the surgical blades is affected.

[0004] Therefore, a kind of scalpel automatic packaging machine is invented to solve the above problems. Summary of the Invention

[0008] Preferably, the guide groove includes a horizontal groove, an oblique groove and a vertical groove connected end to end, a baffle is hinged at the connection point of the vertical groove and the oblique groove, and a torsion spring is provided between the baffle and the guide groove. When the adsorption plate slides toward the direction of the groove, the guide rod slides along the oblique groove, and when the adsorption plate slides in the direction away from the groove, the guide rod slides in sequence along the vertical groove and the horizontal groove.

[0009] Preferably, the driving assembly includes a connecting plate fixedly connected to the adsorption plate, a through push groove is provided on the connecting plate, a transmission rod is slidably connected in the fixed block, a push block is fixed to one end of the transmission rod close to the push groove, and the contact surfaces of the push block and the push groove are both inclined surfaces.

[0012] Preferably, guide blocks are fixed on both sides of the fixing block, and a restraining groove is provided on the guide block. The roller extends into the restraining groove to restrain the lower film and the upper film of the packaging bag.

[0013] Preferably, the machine body is provided with a shearing and hot pressing station for shearing and hot pressing the anti-rust paper onto the lower film of the packaging bag; the machine body is provided with a loading station for automatically placing the scalpel on the cut anti-rust paper; the machine body is provided with a packaging and hot pressing station for hot pressing and sealing the upper and lower films of the packaging bag to wrap the scalpel; the machine body is provided with a cutting station for cutting the scalpel after hot pressing and packaging.

[0016] Technical effects and advantages of the present invention: 1. The present invention is linked to the arrangement of rollers, connecting rods, transmission rods, push blocks, push grooves, adsorption plates and constraint grooves. The rollers are driven to rotate by the friction between the lower film of the packaging bag and the rollers, so that the rollers drive the adsorption plates to slide through the transmission rods, push blocks and push grooves, so that the adsorption plates generate adsorption force through the grooves to adsorb the lower film of the packaging bag into the grooves. The anti-rust paper on the lower film of the packaging bag is just located in the grooves, so that the deviated scalpel slides to the grooves under its own gravity and corrects itself, ensuring that the scalpel can be on the upper side of the anti-rust paper. At the same time, when the rollers rotate in the opposite direction, the friction force can be used to tighten the lower film of the packaging bag near the packaging hot pressing station again, thereby ensuring the flatness of the lower and upper films of the packaging bag, and further ensuring the quality of the hot pressing and packaging of the scalpel.

[0017] 2. The present invention adopts the linkage setting of the leveling plate, the guide groove and the guide rod. When the adsorption plate slides, the two leveling plates can alternately store and release energy under the action of the guide groove and the guide rod, so that the leveling plate can locally tighten the lower film of the packaging bag under the action of friction, thereby ensuring the flatness of the subsequent hot-pressing packaging and ensuring the quality of the hot-pressing packaging.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1 like Figures 1 to 3 As shown, this embodiment provides an automatic packaging machine for surgical knives, including a machine body 1, a lower film station 2 and an upper film station 3, a support plate 201 is provided between the lower film station 2 and the upper film station 3, and a reel 301 is rotatably connected to the upper film station 3.

[0022] The machine body 1 is provided with a shearing and hot-pressing station 7, which is used to shear and hot-press the anti-rust paper onto the lower film of the packaging bag. The machine body 1 is provided with a loading station 8, which is used to automatically place the scalpel on the cut anti-rust paper. The machine body 1 is provided with a packaging and hot-pressing station 9, which is used to hot-press and seal the upper and lower films of the packaging bag to wrap the scalpel. The machine body 1 is provided with a cutting station 10, which is used to cut the scalpel after hot-pressing and packaging.

[0023] A marking station 11 is provided on the upper film station 3 for marking the upper film of the packaging bag. A collecting station 12 is provided at one end of the machine body 1 away from the lower film station 2 for sorting and collecting the empty bags after cutting.

[0024] A transmission mechanism 13 is provided in the machine body 1 for driving the shearing and hot pressing station 7, the loading station 8, the packaging and hot pressing station 9 and the cutting station 10 to perform coordinated and intermittent movements to automatically package the scalpels.

[0025] When in use, first install the upper and lower films of the packaging bag and the anti-rust paper on the corresponding upper film station 3, lower film station 2 and shearing and hot pressing station 7. It should be noted that the lower film station 2, shearing and hot pressing station 7, loading station 8, packaging and hot pressing station 9 and cutting station 10 are arranged in sequence on the machine body 1, and their structures and connection methods are all existing technologies. The specific structure and connection method are not repeated here. After the packaging bag and anti-rust paper are installed, the transmission mechanism 13 is started to drive the above-mentioned stations to perform intermittent and coordinated movement, and the transmission mechanism 13 is existing technology. The specific structure The structure and connection method are no longer described in detail. At this time, the lower film station 2 transports the lower film of the packaging bag from the machine body 1 through different stations in sequence, and makes the lower film of the packaging bag attached to the support plate 201. At the same time, the shearing and hot pressing station 7 cuts the anti-rust paper and hot presses it on the lower film of the packaging bag and transports it to the loading station 8. At this time, the scalpel to be packaged automatically falls on the anti-rust paper through the loading station 8 and is transported to the upper film station 3, so that the upper film of the packaging bag is attached to the lower film of the packaging bag, so that the scalpel is located between the upper film and the lower film of the packaging bag and is transported to the packaging hot pressing station 9. At this time, the packaging hot pressing station 9 performs hot pressing and laminating on the lower film and the upper film of the packaging bag for edge sealing packaging. Since the upper film of the packaging bag is marked when passing through the marking station 11, it is convenient for subsequent cutting. The upper and lower films of the packaging bag after edge sealing packaging are transported to the cutting station 10, and the scalpels after edge sealing packaging are cut by the cutting station 10. The cut scalpels pass through the collecting station 12 to screen the empty bags and collect them. In the above process, the scalpels can be automatically packaged and collected.

[0026] Example 2 During the above-mentioned use, it was found that when the scalpel was placed on the anti-rust paper at the loading station 8, since the scalpel simply tilted onto the anti-rust paper under its own gravity, the position where the scalpel landed on the anti-rust paper would be tilted or offset. This would not only easily cause the anti-rust paper to fail to function, but also easily cause the scalpel to be pressed during hot pressing and packaging, affecting the automatic packaging process. It would also cause the hot pressing and packaging of the scalpel to be loose, so further improvements were made based on the above-mentioned embodiment.

[0027] like Figures 3 to 7 and Figure 9 As shown, the correction component 4 includes a fixed block 402 fixedly connected to the support plate 201 and having a groove 401, and an adsorption plate 403 is slidably connected in the groove 401. When the lower film of the packaging bag moves along the support plate 201, the adsorption plate 403 slides so that the groove 401 generates negative pressure to adsorb the lower film, thereby correcting the deviation of the scalpel on the lower film of the packaging bag.

[0028] The driving component 6 includes a plurality of rollers 601 rotatably connected to the fixed block 402. When the lower mold of the packaging bag moves and drives the rollers 601 to rotate, the adsorption plate 403 slides to assist in correcting the scalpel. The driving component 6 includes a connecting plate 602 fixedly connected to the adsorption plate 403. The connecting plate 602 is provided with a through push groove 603. A transmission rod 604 is slidably connected in the fixed block 402. A push block 605 is fixed to one end of the transmission rod 604 close to the push groove 603. The contact surfaces of the push block 605 and the push groove 603 are both inclined surfaces.

[0029] A plurality of connecting rods 606 are hinged at one end of the transmission rod 604 close to the roller 601 , and the free ends of the connecting rods 606 are eccentrically hinged to the corresponding rollers 601 . A second elastic member 607 is provided between the transmission rod 604 and the fixed block 402 , and a third elastic member 608 is provided between the connecting plate 602 and the fixed block 402 .

[0030] Guide blocks 404 are fixed on both sides of the fixing block 402 . Constraint grooves 405 are formed on the guide blocks 404 . The rollers 601 extend into the constraint grooves 405 to constrain the lower and upper films of the packaging bag.

[0031] When in use, since the lower film and the upper film of the packaging bag are located in the constraint groove 405 during the transportation process, and the roller 601 contacts the lower film of the packaging bag, when the lower film of the packaging bag slides along the constraint groove 405, the lower film of the packaging bag drives the roller 601 to rotate along the fixed block 402 under the action of friction, and the friction between the lower film of the packaging bag and the roller 601 is large enough, the rotation of the roller 601 drives the transmission rod 604 to slide in the direction of the adsorption plate 403 through the eccentrically hinged connecting rod 606, and the second elastic member 607 is compressed, so that the transmission rod 604 drives the pushing block 605 to slide along the pushing groove 603 on the connecting plate 602. Since the contact surfaces of the pushing block 605 and the pushing groove 603 are both inclined surfaces, the pushing block 605 pushes the inclined surface of the pushing groove 603 to drive the connecting plate 602 to slide in the direction of the machine body 1, and the connecting plate 602 drives the adsorption plate 403 to slide along the groove 401. At this time, since the lower film of the packaging bag is attached to the fixed When the suction plate 403 slides, it can generate sufficient negative pressure to adsorb the lower film of the packaging bag. When the anti-rust paper on the lower film of the packaging bag moves to the top of the groove 401 and stops transmitting, the suction plate 403 slides to the extreme position of the groove 401. The negative pressure adsorption force generated by the suction plate 403 through the groove 401 is the largest. Since the lower film of the packaging bag has a certain elasticity, the lower film of the packaging bag undergoes a certain elastic deformation under the action of the negative pressure adsorption force and is concave into the groove 401. The lower film of the packaging bag drives the anti-rust paper to be located in the groove 401. At this time, the upper film of the packaging bag has not yet completely fitted with the lower film, so that the scalpel in the groove 401 can correct itself under the action of its own gravity, so that the scalpel is completely located on the anti-rust paper.

[0032] When the adsorption plate 403 no longer generates adsorption force through the groove 401, under the action of the second elastic member 607, the second elastic member 607 drives the transmission rod 604 to slide in the direction away from the groove 401, and the transmission rod 604 drives the push block 605 to no longer squeeze the push groove 603. Under the action of the third elastic member 608, the third elastic member 608 drives the adsorption plate 403 to slide in the direction away from the body 1 through the connecting plate 602, so that the adsorption plate 403 slides to the initial position and contacts the lower film of the packaging bag again, and the lower film of the packaging bag is not attracted by the negative pressure and its own elastic deformation is restored. The reel 301 is located above the groove 401, so that the lower film of the packaging bag is better attached to the upper film. At the same time, the transmission rod 604 drives the roller 601 to rotate in the opposite direction through the connecting rod 606, so that multiple rollers 601 drive the upper and lower films of the packaging bag near the packaging hot pressing station 9 to be tensioned again, and the roller 601 will not drive the lower film of the packaging bag to move in the opposite direction of the conveying direction, so that the packaging hot pressing station 9 has better hot pressing and packaging quality for the scalpel. When the lower film of the packaging bag continues to be conveyed and the above-mentioned intermittent motion is repeated, the offset scalpel can be automatically corrected to ensure the quality and efficiency of the hot pressing and packaging.

[0033] In summary, through the linkage arrangement of roller 601, connecting rod 606, transmission rod 604, pushing block 605, pushing groove 603, adsorption plate 403 and constraint groove 405, the roller 601 is driven to rotate by the friction between the lower film of the packaging bag and the roller 601, so that the roller 601 drives the adsorption plate 403 to slide through the transmission rod 604, pushing block 605 and pushing groove 603, so that the adsorption plate 403 generates an adsorption force through the groove 401 to adsorb the lower film of the packaging bag into the groove 401, and the anti-rust paper on the lower film of the packaging bag is just located in the groove 401, so that the deviated scalpel slides to the groove 401 under its own gravity and corrects itself, ensuring that the scalpel can be on the upper side of the anti-rust paper. At the same time, when the roller 601 rotates in the opposite direction, the lower film of the packaging bag near the packaging hot pressing station 9 can be tightened again by friction, thereby ensuring the flatness of the lower and upper films of the packaging bag, and further ensuring the quality of the hot pressing and packaging of the scalpel.

[0034] Example 3 During the above-mentioned use process, it was also found that after the adsorption plate 403 adsorbed the lower film of the packaging bag through the groove 401, the lower film of the packaging bag was easily loosened during the process of restoring the lower film of the packaging bag to its original shape, resulting in the problem of improper fitting between the lower film and the upper film of the packaging bag, which ultimately affected the quality of the subsequent hot pressing packaging. Therefore, further improvements were made based on the above-mentioned embodiment.

[0035] like Figures 7 to 9As shown, the leveling assembly 5 includes two leveling plates 501 that are slidably connected to the adsorption plate 403. When the adsorption plate 403 slides, the leveling plates 501 slide relative to or away from each other; the leveling assembly 5 includes two guide rods 502 fixedly connected to the leveling plates 501, and two guide grooves 503 corresponding to the guide rods 502 are provided on the side walls of the groove 401. The guide rods 502 are slidably connected to the guide grooves 503, and the guide rods 502 and the adsorption plate 403 are connected by a first elastic member 504.

[0036] The guide groove 503 includes a horizontal groove 5031, an oblique groove 5032 and a vertical groove 5033 connected end to end. A baffle 5034 is hinged at the connection point between the vertical groove 5033 and the oblique groove 5032. A torsion spring 5035 is provided between the baffle 5034 and the guide groove 503. When the adsorption plate 403 slides toward the direction of the groove 401, the guide rod 502 slides along the oblique groove 5032. When the adsorption plate 403 slides in the direction away from the groove 401, the guide rod 502 slides in sequence along the vertical groove 5033 and the horizontal groove 5031.

[0037] During use, when the adsorption plate 403 slides along the groove 401 toward the body 1, since the horizontal groove 5031, the oblique groove 5032 and the vertical groove 5033 form a right triangle, and the initial state of the guide rod 502 is located at the connection point of the oblique groove 5032 and the horizontal groove 5031, the adsorption plate 403 drives the smoothing plate 501 to slide, and the guide rod 502 slides along the oblique groove 5032 toward the body 1. Under the action of the oblique groove 5032, the guide rod 502 drives the two smoothing plates 501 to slide relative to each other along the adsorption plate 403. An elastic member 504 is compressed. When the adsorption plate 403 slides to the maximum distance in the direction of the body 1, the guide rod 502 slides along the inclined groove 5032 to the connection with the vertical groove 5033, so that the guide rod 502 pushes the baffle 5034 to swing in the direction of the vertical groove 5033, and the torsion spring 5035 is wound. At this time, the guide rod 502 slides from the inclined groove 5032 into the vertical groove 5033 and no longer squeezes the baffle 5034, so that the torsion spring 5035 drives the baffle 5034 to block the connection between the vertical groove 5033 and the inclined groove 5032 again.

[0038] When the suction plate 403 slides in the direction away from the body 1, a limiting groove is provided at the hinge point of the baffle 5034 and the fixed block 402 to limit the swing amplitude of the baffle 50324. Due to the limitation of the side wall of the limiting groove, the guide rod 502 will not push the baffle 5034 to swing in the direction of the inclined groove 5032, so that the guide rod 502 will not enter the inclined groove 5032 and slide along the vertical groove 5033, so that the guide rod 502 can only slide along the vertical groove 5033 first, so that the first elastic member 504 is in a compressed state. When the suction plate 403 slides and contacts the lower film of the packaging bag again, the first elastic member 504 is compressed. The smoothing plate 501 is in contact with the lower film of the packaging bag, and the guide rod 502 slides to the connection point of the vertical groove 5033 and the horizontal groove 5031. Under the action of the first elastic member 504, the first elastic member 504 drives the two smoothing plates 501 to slide back to back along the adsorption plate 403 through the guide rod 502, and the guide rod 502 slides to the initial position along the horizontal groove 5031, so that the smoothing plate 501 drives the lower film of the packaging bag located in the groove 401 to be tensioned to both sides through the friction between the smoothing plate 501 and the lower film of the packaging bag, so that the upper film of the packaging bag is better attached to the lower film of the packaging bag, which is beneficial to the quality of subsequent hot pressing and packaging.

[0039] In summary, through the linkage setting of the smoothing plate 501, the guide groove 503 and the guide rod 502, when the adsorption plate 403 slides, the two smoothing plates 501 can alternately store and release energy under the action of the guide groove 503 and the guide rod 502, so that the smoothing plate 501 can locally tighten the lower film of the packaging bag under the action of friction, thereby ensuring the flatness of the subsequent hot-pressed packaging and ensuring the quality of the hot-pressed packaging.
