Description

Technical Field

[0001] This invention relates to the field of medical packaging film processing equipment technology, specifically to a plastic cutting material recycling device for medical packaging film processing. Background Technology

[0002] Medical packaging film is a special material used in the medical industry for packaging medical devices, pharmaceuticals, and other medical supplies. It provides a physical and chemical barrier, effectively preventing the intrusion of microorganisms, dust, moisture, and other contaminants, ensuring the sterility of the contents. Its high transparency allows for clear visibility of the contents, facilitating inspection and identification. Before packaging, medical packaging film undergoes an edge-trimming process to remove any burrs, unevenness, or weakened areas from the film edges. These not only affect the appearance of the packaging but, more importantly, can lead to poor sealing during heat sealing, thus compromising the sterile barrier performance of the packaging. Smooth, clean edges improve the strength and reliability of the heat seal.

[0003] Currently, after the sides of medical packaging film are cut, a plastic scrap recycling device with a guiding structure is used to collect the scrap to ensure the stability of scrap recycling. Inside the device, a cutter then shreds the recycled strips of scrap. However, this type of plastic scrap recycling device has the following problems:

[0004] 1. Although it can stably cut and recycle edge materials with small width variations, it is difficult to make adaptive adjustments for recycling edge materials with larger widths. When the guide width exceeds the recycling width, the guide structure cannot make adaptive adjustments to the recycled edge materials, thus reducing the stability of edge material recycling.

[0005] 2. After each medical packaging film is trimmed, each trimming production line generally produces a small amount of scrap material, which needs to be collected separately on each production line and then transferred together. However, dust and other impurities will be mixed in during the transfer process, which increases the difficulty of scrap material recycling and reduces recycling efficiency.

[0006] In summary, there is a need for a device that can efficiently and stably recycle medical packaging film cuttings. Summary of the Invention

[0023] 1.

When adjusting the position of the cutting blade, the width limiting structure of the guide mechanism is adjusted simultaneously, so that the width limiting structure of the guide mechanism can adaptably convey the edge material of the corresponding width, thereby ensuring the stability of conveying the edge material cut from the packaging film.

[0024] 2. By feeding the edge material cut off from both sides of the medical packaging film into two sets of feeding and cutting mechanisms for chopping, and then collecting the shredded material from the two sets of feeding and cutting mechanisms into the casing through the extrusion and collection mechanism, the shredded material from each conveyor table is further collected through the air duct, thereby improving the efficiency of edge material collection and recycling.

[0025] 3. When adjusting the width of the slitting edge material, the sliding pusher moves the push plate inside the slitting box, so that the cutting component and the edge clamping component can move to adapt to slitting edge materials of different widths.

[0026] 4. When the width of the slit edge material increases, the pushing component is stopped by the slitting box and inserted into the first rotating column. The pushing component pushes out the first and second fine cutting components, so that the slitting density of the outer wall of the first rotating column is higher, thereby enabling the slitting of the slit edge material with increased width to be cut into smaller pieces, improving the convenience of edge material slitting and recycling.

[0044] Example 1

[0045] To address the technical problems in the background section, the following plastic cutting material recycling device for medical packaging film processing is provided:

[0046] Combination Figures 1-14 As shown, the plastic cutting material recycling device for medical packaging film processing provided by the present invention includes an air duct 5 and multiple conveying platforms 1. The bottom surface of the air duct 5 is connected to a squeezing mechanism 6. Multiple branch pipes 51 are connected to one side of the air duct 5. One end of the branch pipe 51 is connected to a housing 4. A cutting component 2 is provided on one side of the conveying platform 1. A cutting module 3 is provided on the top surface of the conveying platform 1. Two sets of cutting modules 3 are mirrored about the vertical center line of the conveying platform 1. One side of each set of cutting modules 3 is inserted into the housing 4.

[0047] The cutting module 3 includes an outlet pipe 31, a cutting mechanism 32, a guiding mechanism 33, a side baffle 34, a fixing bolt 35, and a third positioning plate 36. The guiding mechanism 33 is provided on one side of the side baffle 34, and the cutting mechanism 32 is provided on the top surface of the guiding mechanism 33. The outlet pipe 31 is connected through the top surface of the cutting mechanism 32. One end of the outlet pipe 31 is inserted into the inside of the housing 4. The fixing bolt 35 is connected inside the side baffle 34. The top surface of the conveying table 1 has a sliding interface 11. The fixing bolt 35 is connected through the sliding interface 11. The bottom end of the fixing bolt 35 is connected to the third positioning plate 36. One side of the guiding mechanism 33 is sleeved inside the edge cutting assembly 2. The guiding mechanism 33 is used to transport the edge material cut by the edge cutting assembly 2.

[0048] The edge-cutting assembly 2 includes a fixed frame 21, a drive roller 22, an edge-cutting blade 23, a steering roller 24, and a support roller 25. The fixed frame 21 is fixed to the side wall of the conveyor table 1. There are two fixed frames 21 mirror images of the vertical center line of the conveyor table 1.

One side of the guide mechanism 33 is rotatably sleeved with one side of the edge-cutting blade 23. The guide mechanism 33 has a width-limiting structure inside. The width-limiting structure of the guide mechanism 33 adjusts the guide width by moving the edge-cutting blade 23.

[0049] The following effects can be achieved based on the above structure:

[0050] 1. By setting the guide mechanism 33 with the cutting mechanism 32 on the side baffle 34, it is only necessary to adjust the fixed position of the side baffle 34 to adjust the width of the medical packaging film to be cut, and then adjust the position of the cutting blade 23 on the drive roller 22 to set the width of the cut edge material. When adjusting the position of the cutting blade 23, the width limiting structure of the guide mechanism 33 is adjusted simultaneously, so that the width limiting structure of the guide mechanism 33 can adaptably transport the edge material of the corresponding width, thereby ensuring the stability of the transport of the edge material cut from the packaging film.

[0051] 2. By feeding the edge material cut off from both sides of the medical packaging film into the two sets of feeding and cutting mechanisms 32 for chopping, and then collecting the shredded material from the two sets of feeding and cutting mechanisms 32 into the casing 4 through the extrusion and collection mechanism 6, the extrusion and collection mechanism 6 further collects the shredded edge material on each conveyor table 1 through the air pipe 5, thereby improving the efficiency of edge material collection and recycling.

[0052] In this embodiment, the guiding mechanism 33 includes a sleeve 331, a connecting plate 332, a guide frame 333, a first fixed plate 334, a first support plate 335, a first guiding roller 336, a second support plate 337, a sliding pusher 338, and a second guiding roller 339.

[0053] A fixing cylinder 231 is fixed to one side of the cutting blade 23. An annular positioning groove 2311 is formed on the outer wall of the fixing cylinder 231. The sleeve 331 is fitted onto the outer wall of the fixing cylinder 231. A positioning bolt 3311 is connected through the outer wall of the sleeve 331, with its bottom end positioned inside the positioning groove 2311. A connecting plate 332 is fixed to the side wall of the sleeve 331. A second guide roller 339 is rotatably connected to the bottom surface of the connecting plate 332. A second stop bracket 3341 is fixed to the top surface of the first fixing plate 334. The second guide roller 339 is connected through the interior of the second stop bracket 3341. A sliding pusher 338 is fixed on the top surface of the plate 332. A first guide roller 336 is rotatably connected to one side of the sliding pusher 338.

A U-shaped guide frame 333 is fixed on the bottom surface of the sliding pusher 338. The guide frame 333 is located between the first guide roller 336 and the second guide roller 339. Both ends of the first guide roller 336 and the second guide roller 339 are provided with circular plate structures to stop the edge material.

[0054] When the slitting blade 3234 adjusts the width of the slitting edge material, the connecting plate 332 drives the first guide roller 336 and the second guide roller 339 to move to adjust the conveying width of the first guide roller 336 and the second guide roller 339, thereby ensuring the stability of the edge material conveying.

[0055] In this embodiment, the second support plate 337 is fixed with the second positioning plate 3371, and the side wall of the sliding pusher 338 is connected with the third guide rod 3381, which is connected through the interior of the second positioning plate 3371.

[0056] In this embodiment, the cutting mechanism 32 includes a slitting box 321, an air inlet fan 322, a cutting assembly 323, an edge clamping assembly 324, a push plate 325, a second motor 326, a first clamping roller 327, and a second clamping roller 328. The push plate 325 is disposed inside the slitting box 321, and the bottom surface of the push plate 325 is fixedly connected to the top surface of the sliding pusher 338. The cutting assembly 323 and the edge clamping assembly 324 are disposed on one side of the push plate 325. One side of component 324 is connected through to the inside of the slitting box 321.

One side of the slitting box 321 is provided with an air inlet fan 322. One side of the air inlet fan 322 is connected through to the inside of the slitting box 321.

[0057] After the slit edge material is guided into the slitting box 321 by the first guide roller 336, the first clamping roller 327 is driven by the second motor 326 and cooperates with the second clamping roller 328 to convey the edge material upward. The edge material is slit by the cutting component 323 and the clamping component 324, and the slitting operation is stable.

[0058] Example 2

[0059] like Figures 8-12 As shown, based on the above embodiments, this embodiment further provides the following:

[0060] After increasing the cutting width of the edge material, it is difficult to adapt to cutting edge materials of different widths. Moreover, the cutting interval is fixed, which makes the fragments cut from the edge material with increased width larger, thus affecting the stability of recycling. To solve the above problems, the following structure is adopted.

[0061] The cutting assembly 323 includes a pusher component 3231, a first gear 3232, a first rotating column 3233, a slitting blade 3234, a first guide rod 3235, a first precision cutting component 3236, and a second precision cutting component 3237.

Multiple sets of first precision cutting components 3236 and second precision cutting components 3237 are arranged inside the first rotating column 3233. The first precision cutting component 3236 and the second precision cutting component 3237 have the same structure. One side of the first precision cutting component 3236 and the second precision cutting component 3237 extends outward from the outer wall of the first rotating column 3233. One end of the first guide rod 3235 is connected to the first gear 3232. One side of the first gear 3232 is meshed with the clamping assembly 324. A pushing component 3231 is connected through the first gear 3232. One side of the pushing component 3231 is inserted into the first rotating column 3233. The pushing component 3231 pushes out the first precision cutting component 3236 and the second precision cutting component 3237 extending outward from the outer wall of the first rotating column 3233 by inserting into the first rotating column 3233.

[0062] When adjusting the width of the slitting edge material, the sliding pusher 338 drives the pusher plate 325 to move inside the slitting box 321, so that the cutting component 323 and the edge clamping component 324 can move to adapt to slitting edge materials of different widths.

[0063] When the width of the slit edge material increases, the pushing component 3231 is stopped by the slitting box 321 and inserted into the first rotating column 3233. The pushing component 3231 pushes out the first fine cutting component 3236 and the second fine cutting component 3237, so that the slitting density of the outer wall of the first rotating column 3233 is higher, thereby enabling the slitting of the slit edge material with increased width to be cut into smaller pieces, improving the convenience of edge material slitting and recycling.

[0064] In this embodiment, the pushing component 3231 includes a pushing plate 32311, a first insert rod 32312, a first inclined push block 32313, a second insert rod 32314, and a second inclined push block 32315. A plurality of first insert rods 32312 and second insert rods 32314 are connected to one side of the pushing plate 32311. The first insert rods 32312 and second insert rods 32314 are spaced apart along the circumference of the pushing plate 32311. 2. The second insert rod 32314 is inserted into the first rotating column 3233. The first insert rod 32312 is connected to the first inclined push block 32313 at the end away from the push plate 32311. One side of the first inclined push block 32313 is fitted with the first precision cutting component 3236. The second insert rod 32314 is connected to the second inclined push block 32315 at the end away from the push plate 32311. One side of the second inclined push block 32315 is spaced apart from the second precision cutting component 3237.

[0065] When the push plate 32311 is stopped by the inner wall of the slitting box 321, the first insert rod 32312 and the second insert rod 32314 are inserted into the first rotating column 3233. The first inclined push block 32313 first pushes the first fine cutting component 3236 out from the inside of the first rotating column 3233, so that each set of extended first fine cutting components 3236 and slitting blade 3234 cooperate to cut the edge material to reduce the size of the cut edge material. When the width of the edge material is further increased, the second inclined push block 32315 continues to move to push out the second fine cutting component 3237, thereby further refining the cut edge material to ensure stable edge material recycling.

[0066] In this embodiment, the first precision cutting component 3236 includes a spare cutting blade 32361, a top block 32362, a third insert rod 32363, and a spring 32364. The spare cutting blade 32361 is disposed inside the first rotating column 3233, with one side of the spare cutting blade 32361 extending outward from the outer wall of the first rotating column 3233. The top block 32362 is fixed to the bottom surface of the spare cutting blade 32361. One side of the top block 32362 has a sloping structure and is fitted to the sloping surface of the first inclined push block 32313. The bottom surface of the spare cutting blade 32361 is connected to the third insert rod 32363. The spring 32364 is sleeved on the outer wall of the third insert rod 32363, and the bottom end of the spring 32364 is connected to the inside of the first rotating column 3233.

[0067] In this embodiment, the clamping assembly 324 includes a first motor 3241, a second gear 3242, a second rotating column 3243, clamping columns 3244, and a second guide rod 3245. The second guide rod 3245 is connected through the inside of the push plate 325. The second rotating column 3243 is sleeved on the outer wall of the second guide rod 3245. The first motor 3241 is disposed on the side wall of the push plate 325. The second gear 3242 is sleeved on the outer wall of the shaft of the first motor 3241. One side of the second gear 3242 is meshed with the first gear 3232. The rotating end of the first motor 3241 is fixedly connected to one end of the second guide rod 3245. Multiple clamping columns 3244 are provided on the outer wall of the second rotating column 3243.

[0068] Example 3

[0069] like Figure 8 , Figure 13 and Figure 14 As shown, based on the above embodiments, this embodiment further provides the following:

[0070] To achieve the above effect, the following structure is adopted;

[0071] A sealing plate 3251 is fixed to the top side wall of the push plate 325. The sealing plate 3251 is inserted into the inside of the cutting box 321. A first positioning plate 3252 is fixed to the side of the sealing plate 3251 away from the push plate 325.

[0072] When cutting narrower edge materials, the push plate 325 and the baffle plate 3251 reduce the cutting space where the first rotating column 3233 and the second rotating column 3243 are located, thereby increasing the internal airflow speed and improving the flow speed of the cut edge materials, so as to make the edge materials recover faster and ensure the stability of edge material recovery.

[0073] When cutting wider edge material, the push plate 325 and the baffle plate 3251 increase the cutting space of the first rotating column 3233 and the second rotating column 3243, thereby avoiding blockage of larger edge material and further improving the stability of edge material recycling.

[0074] In this embodiment, the extrusion and collection mechanism 6 includes a recovery tank 61, an extrusion cylinder 62, a cutting ring 63, a pneumatic rod 64, a feeding hopper 65, a blower 66, a third motor 67, a turntable 68, and hot press rollers 69. The top surface of the recovery tank 61 is connected to the air duct 5. The extrusion cylinder 62 is fixed inside the recovery tank 61. The turntable 68 is installed inside the extrusion cylinder 62. Two hot press rollers 69 are rotatably connected to the top surface of the turntable 68. The bottom surface of the extrusion cylinder 62 is equipped with a third motor 67. The top of the third motor 67 extends through the inside of the extrusion cylinder 62 and is connected to the bottom surface of the turntable 68. The outer wall of the extrusion cylinder 62 has a stepped structure, and the top diameter is larger than the bottom diameter. A second fixing plate 622 is fixed to the wall. A cutting ring 63 is sleeved on the bottom outer wall of the extrusion cylinder 62. The cutting ring 63 is slidably connected to the inside of the second fixing plate 622. A slider 631 is fixed to the side wall of the cutting ring 63. The slider 631 is slidably connected to the outer wall of the recycling tank 61. A pneumatic rod 64 is set on the outer wall of the recycling tank 61. The telescopic bottom end of the pneumatic rod 64 is connected to the bottom surface of the slider 631. An extrusion hole 623 is opened through the bottom outer wall of the extrusion cylinder 62. An air hole 621 is opened through the top interior of the extrusion cylinder 62. A feeding hopper 65 is set at the bottom of the extrusion cylinder 62. The bottom end of the feeding hopper 65 extends outward from the bottom surface of the recycling tank 61. The inside of the feeding hopper 65 is a sieve structure. A blower 66 is connected through the side wall of the recycling tank 61.

[0075] After the slit edge material is drawn into the extrusion cylinder 62 by the exhaust fan 66, the edge material is heated and rolled by the hot pressure roller 69 and extruded from the extrusion hole 623. Then, the extruded edge material is cut off by the cutting ring 63, which facilitates the recycling and reuse of the edge material.

[0076] Working principle and usage process of this invention:

[0077] First press Figures 1-14Adjust the side baffle 34 on the conveyor table 1 to accommodate the width of the medical packaging film being processed. Then, move the adjustment blade 23 on the drive roller 22 to determine the width of the edge material to be cut. When moving the adjustment blade 23, the sleeve 331 drives the connecting plate 332 to move, so that the first guide roller 336 slides inside the first stop bracket 3211 and the second guide roller 339 slides inside the second stop bracket 3341, so that the limit width of the edge material conveyed on the first guide roller 336 and the second guide roller 339 is limited.

[0078] Then, the medical packaging film is inserted between the steering roller 24 and the support roller 25 for turning and conveying. During the conveying process, the drive roller 22 is started, and the drive roller 22 drives the cutting blade 23 to rotate and cut the edge of the medical packaging film. The film to be packaged is guided and conveyed through the two side baffles 34 after cutting. The edge material cut off by the cutting blade 23 is turned by the second guide roller 339, and then passes through the inside of the guide frame 333, and then enters the slitting box 321 through the first guide roller 336.

[0079] The air intake fan 322 and the exhaust fan 66 are started, and the edge material is fed between the first clamping roller 327 and the second clamping roller 328. The first motor 3241 and the second motor 326 are started. The second motor 326 drives the first clamping roller 327 to continue to feed the edge material upward. The edge material enters between the first rotating column 3233 and the second rotating column 3243. The second motor 326 drives the second rotating column 3243 and the second gear 3242 to rotate. The second gear 3242 meshes with the first gear 3232 for transmission. The cutting blade 3234 and the clamping column 3244 cooperate to cut the edge material into fragments.

[0080] The scrap material flows into the outlet pipe 31 through the slitting box 321. At this time, the slitting space between the push plate 325 and the sealing baffle 3251 is relatively narrow, which allows the smaller scrap material to flow into the outlet pipe 31 quickly. Then, it passes through the sleeve box 4 to collect the scrap material slid on both sides. Then, it is collected from the slid on each conveyor table 1 through the air pipe 5 and sent to the recycling tank 61. The third motor 67 and the hot pressure roller 69 are started. The scrap material inside the recycling tank 61 enters the extrusion cylinder 62. The hot pressure roller 69 heats the scrap material and rotates and rolls it, extruding the heated and softened scrap material onto the outer wall of the extrusion cylinder 62. Then, the pneumatic rod 64 is started to push the slider 631 downward. The cutting ring 63 cuts the extruded scrap material downward, so that the scrap material falls in granular form and is discharged through the feed hopper 65.

[0081] As the width of the removed edge material increases, the connecting plate 332 drives the adjustment of the limiting width of the first guide roller 336 and the second guide roller 339. At the same time, the push plate 325 moves to increase the cutting space inside the slitting box 321. Simultaneously, under the stop on the inner wall of the slitting box 321, the push plate 32311 is pushed to insert the first insert rod 32312 and the second insert rod 32314 into the first rotating column 3233. The first inclined push block 32313 pushes out the pre-cutting blade 32361 of the first fine cutting component 3236 to increase the cutting frequency of the edge material. The second inclined push block 32315 moves towards the second fine cutting component 3237. When the width of the removed edge material is further increased, the second inclined push block 32315 continues to be pushed, so that the second inclined push block 32315 pushes out the second fine cutting component 3237, further increasing the cutting frequency of the edge material to ensure that the slitting fragments are not too large, thereby ensuring the stability of edge material recycling.
