Description

Technical Field

[0001] The present invention relates to the technical field of slitting, and particularly to a slitting device for the production of medical sterile dressings. Background Art

[0002] With the rapid development of the medical industry, medical sterile dressings, as commonly used consumables in clinical treatment and wound care, have an increasing market demand. The slitting quality of the dressings directly affects their performance. For example, the flatness of the edges, the rationality of the breakpoint design, etc., are all related to the patient's usage experience and treatment effect. However, the existing slitting devices for the production of medical sterile dressings have many deficiencies. Traditional devices mostly use single - time complete cutting, and the cutting tool needs to cut in at a large depth at one time, which makes the shear force and pressure on each layer of the dressing material uneven, and it is easy to appear problems such as burrs, curling and deformation, resulting in a low product qualification rate and being difficult to meet medical standards. In terms of positioning, the positioning structure of some devices is simple and cannot effectively limit the movement of the dressing during the slitting process, further exacerbating the uneven cutting situation. In the breakpoint processing link, some devices lack automated design and rely on manual marking and cutting breakpoints, with low efficiency and unstable breakpoint quality. Even when using the method of directly cutting round holes to set breakpoints, it is necessary to additionally configure complex waste collection devices, increasing equipment costs and occupying production space, making the production process more cumbersome. In addition, the maintenance of cutting tools is also a major problem. Traditional devices often require manual grinding or replacement of cutting tools regularly, which not only consumes a lot of manpower and time, but also the frequent tool replacement increases production costs, and the downtime for maintenance reduces equipment utilization and production efficiency. For this reason, we propose a slitting device for the production of medical sterile dressings. Summary of the Invention

[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0015] 1. The present invention provides a medical sterile dressing production slitting device, which drives the first rotating rod through a double-headed motor to drive the first swing rod, the first positioning rod and the second swing rod to operate in coordination, so that the sliding block on the mounting rod reciprocally slides in the limiting chute of the lifting frame, and then drives the electric cutting wheel to perform reciprocating cutting. When adopting the reciprocating cutting mode, there is no need for the tool to perform a one-time deep cut, but the cutting task is gradually completed through multiple shallow cuts. Each cutting depth is relatively shallow, and the shearing force and pressure on the material are relatively uniform. The outer layer material will not be overstretched due to excessive instantaneous force, and the inner layer material can also be fully cut off during multiple cutting processes, effectively avoiding the generation of burrs caused by uneven force. At the same time, the uniform stress state ensures the integrity of each part of the dressing, greatly reducing the phenomenon of curling and deformation, significantly improving the cutting quality and finished product qualification rate of the medical sterile dressing, making the product more in line with medical standards and enhancing the market competitiveness.

[0016] 2. The present invention provides a medical sterile dressing production slitting device. During the downward movement of the lifting frame, the first sliding rod slides in the first sliding hole, the first positioning frame is pressed down under the action of the first spring to initially position the dressing, the connecting plate drives the second sliding rod to slide in the second sliding hole, and the second positioning frame is further pressed down under the action of the second spring to achieve precise positioning of the dressing, avoiding displacement during the slitting process, resulting in curling or uneven cutting. The double positioning structure utilizes the elastic force of the spring to closely fit the dressing, effectively restricting the movement of the dressing during slitting, ensuring the neatness and smoothness of the slitting edge, and improving the product quality.

[0017] 3. The present invention provides a medical sterile dressing production slitting device, which drives the second rotating rod to rotate through a double-headed motor. The second rotating rod is driven by the first rotating rod and the second rotating rod, and is limited by the third rotating rod and the fourth rotating rod to push the first positioning slider and the second positioning slider to slide in the positioning holes, realizing the automatic lifting of the lifting rod driven cutting blade, performing a breakpoint treatment on the center of the dressing, and at the same time forming a cross incision, which is convenient for the subsequent insertion of the drainage tube of the dressing. This design realizes the automation of the breakpoint treatment, without additional manual operation, improves the production efficiency, the cross incision can be flexibly expanded according to the insertion requirements of the drainage tube, reduces the insertion difficulty, and enhances the practicability and applicability of the dressing. Compared with the method of directly cutting a round hole and separately collecting the waste, this design does not require additional complex waste collection devices and processes, avoids the problems of occupying production space due to waste collection, increasing equipment costs and maintenance difficulties, effectively simplifies the production process, and reduces the comprehensive production cost.

[0018] 4. The present invention provides a medical sterile dressing production slitting device. When the lifting frame moves upward, the rack of the first positioning frame meshes with the second gear, drives the control wheel to rotate through the support rod, and the first gear of the rotating frame meshes with the incomplete gear on the control wheel. After the electric cutting wheel rotates one week, it deflects under the action of the torsion spring and contacts the grinding plate for grinding, realizing the automatic grinding on both sides of the electric cutting wheel, continuously maintaining the sharp state of the cutting wheel, making the edges of the slit dressing flat, effectively avoiding problems such as burrs and uneven cutting, improving the product quality, reducing the replacement frequency of the cutting wheel due to excessive wear, reducing the tool procurement cost, and at the same time reducing the maintenance cost and downtime of the equipment caused by frequent disassembly and assembly of the cutting wheel, and improving the equipment utilization rate.

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0030] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0031] As shown Figures 1-9 in the figure, a medical sterile dressing production and cutting device includes a frame 1. A moving mechanism 2 is arranged inside the frame 1. The moving mechanism 2 includes a first rotating rod 201 and a lifting frame 202. A first swinging rod 203 is fixedly connected to the outer surface of the first rotating rod 201. The outer surface of the first swinging rod 203 is rotatably connected to a first positioning rod 204 through a bearing. A plurality of second swinging rods 205 are rotated on the outer surface of the positioning rod. An installation rod 206 is rotatably connected to the inner surface of the second swinging rod 205. A sliding block 207 is fixedly connected to the upper surface of the installation rod 206. A limiting sliding groove 208 is opened on the inner surface of the lifting frame 202. The sliding block 207 is slidably connected to the limiting sliding groove 208. An installation frame 209 is fixedly connected to the lower surface of the installation rod 206. An installation plate 210 is rotatably connected to the inner surface of the installation frame 209 through a bearing. A rotating frame 211 is rotatably connected to the inner surface of the installation plate 210 through a bearing. An electric cutting wheel 212 is fixedly installed on the lower surface of the rotating frame 211.

[0032] The effect is that the first swinging rod 203 outside the first rotating rod 201 rotates accordingly, drives the second swinging rod 205 to move through the first positioning rod 204, so that the sliding block 207 on the installation rod 206 slides in the limiting sliding groove 208 of the lifting frame 202. During the swinging process of the second swinging rod 205, it will drive the symmetrically arranged first positioning rod 204 to move, so that the sliding block 207 can reciprocally slide inside the limiting sliding groove 208, thereby driving the installation frame 209, the installation plate 210, the rotating frame 211 and the electric cutting wheel 212 to move horizontally. The electric cutting wheel 212 cuts the dressing. During the cutting process, the cylinder 9 drives the electric cutting wheel 212 to gradually descend and reciprocally cut the dressing. During the cutting operation, the electric cutting wheel 212 starts to cut the positioned medical sterile dressing, and gradually cuts the dressing as the cutting wheel rotates.

[0033] As shown Figures 1-9 in the figure, a positioning mechanism 3 is arranged on the lower surface of the lifting frame 202. The positioning mechanism 3 includes a plurality of first sliding rods 301. A plurality of first sliding holes 302 are opened on the outer surface of the lifting frame 202. The plurality of first sliding holes 302 are slidably connected to the first sliding rods 301. A first positioning frame 303 is fixedly connected to the lower surface of the plurality of first sliding rods 301. A first spring 304 is fixedly connected between the lifting frame 202 and the first positioning frame 303. A connecting rod 305 is fixedly connected to the lower surface of the lifting frame 202. A connecting plate 306 is fixedly connected to the lower surface of the connecting rod 305. A plurality of second sliding holes 307 are opened on the outer surface of the connecting plate 306. A second sliding rod 308 is slidably connected to the inner surface of each of the plurality of second sliding holes 307. A second positioning frame 309 is fixedly connected to the lower surface of the plurality of second sliding rods 308. A second spring 310 is fixedly connected between the connecting plate 306 and the second positioning frame 309.

[0034] The effect is that during the downward movement of the lifting frame 202, the first sliding rod 301 slides in the first sliding hole 302, and the first positioning frame 303 is pressed down under the action of the first spring 304 to initially position the dressing. The connecting plate 306 drives the second sliding rod 308 to slide in the second sliding hole 307, and the second positioning frame 309 is further pressed down under the action of the second spring 310 to achieve precise positioning of the dressing, avoiding displacement during the slitting process, resulting in curling or uneven cutting.

[0035] As Figures 1-9 shown, a break point mechanism 4 is provided on the lower surface of the connecting plate 306. The break point mechanism 4 includes a second rotating rod 401. The outer surface of the second rotating rod 401 is rotatably connected to a first rotating rod 402 through a bearing. The outer surface of the first rotating rod 402 is rotatably connected to a second rotating rod 403 through a bearing. A plurality of positioning holes 404 are formed on the outer surface of the connecting plate 306. The inner surfaces of the plurality of positioning holes 404 are slidably connected to a first positioning slider 405 and a second positioning slider 406. The outer surfaces of the plurality of first positioning sliders 405 are rotatably connected to a third rotating rod 408 through a bearing. The outer surfaces of a plurality of positioning sleeves 407 are rotatably connected to a third rotating rod 408 through a bearing. The lower surfaces of the plurality of second positioning sliders 406 are rotatably connected to a fourth rotating rod 409 through a bearing. The plurality of third rotating rods 408 and the fourth rotating rods 409 are rotatably connected through a bearing. The lower surfaces of the plurality of first positioning sliders 405 are fixedly connected to a positioning sleeve 407. The inner surfaces of the plurality of positioning sleeves 407 and the first positioning sliders 405 are slidably connected to a lifting rod 410. The upper surfaces of the plurality of lifting rods 410 are fixedly connected to a clamping rod 411. Guide grooves 412 are formed on the inner surfaces of the plurality of positioning holes 404. The plurality of clamping rods 411 are slidably connected to the guide grooves 412. The lower surfaces of the plurality of lifting rods 410 are fixedly connected to a cutting blade 413.

[0036] The effect is that the second rotating rod 401 is driven by the first rotating rod 402 and the second rotating rod 403, and limited by the third rotating rod 408 and the fourth rotating rod 409, which can push the first positioning slider 405 and the second positioning slider 406 to slide in the positioning hole 404, so that the positioning sleeve 407 provided at the bottom of the first positioning slider 405 can drive the lifting rod 410 to move. At the same time, the clamping rod 411 at the top of the lifting rod 410 can stably slide inside the guide groove 412 when the lifting rod 410 moves, thereby driving the lifting rod 410 to move up and down in the positioning sleeve 407 and the first positioning slider 405. When the lifting rod 410 descends, the cutting blade 413 on its lower surface performs a break point treatment on the center of the dressing to form a break point that is convenient to tear, and a plurality of cutting blades 413 are provided, which can be cut into a cross incision to facilitate the insertion of the drainage tube of the dressing in the future.

[0037] As shown Figures 1-9 in the figure, a grinding mechanism 5 is further arranged inside the frame 1. The grinding mechanism 5 includes two control wheels 501. Two fixing plates 502 are fixedly connected to the inner surface of the mounting frame 209. The outer surfaces of the two fixing plates 502 are rotatably connected to a support rod 503 through bearings. The support rod 503 is fixedly connected to the control wheel 501. An incomplete gear 504 and a guide block 505 are respectively fixedly connected to the outer surfaces of the opposite sides of the two control wheels 501. A first gear 506 is fixedly connected to the upper surface of the rotating frame 211. The first gear 506 is meshed with the incomplete gear 504. A resisting block 507 is fixedly connected to the upper surface of the first gear 506. The resisting block 507 is movably connected to the guide block 505. A grinding plate 508 is fixedly connected to the outer surface of the first positioning frame 303. A rack 6 is fixedly connected to the outer surface of the first positioning frame 303. The end of the support rod 503 is fixedly connected to a second gear 13. The second gear 13 is meshed with the rack 6. A conveyor belt 7 and a collection box 8 are installed on the outer surface of the frame 1. An air cylinder 9 is installed on the inner surface of the frame 1. The output end of the air cylinder 9 is fixedly connected to the lifting frame 202. A limiting plate 10 is fixedly connected to the upper surfaces of a plurality of first sliding rods 301. A plurality of first springs 304 are respectively sleeved on the outer surfaces of the first sliding rods 301. A plurality of second springs 310 are respectively sleeved on the outer surfaces of the second sliding rods 308. A fixing frame 11 is fixedly connected to the lower surface of the lifting frame 202. A double-headed motor 12 is fixedly connected to the outer surface of the fixing frame 11. A first rotating rod 201 and a second rotating rod 401 are respectively fixedly connected to the output end of the double-headed motor 12. The first rotating rod 201 is rotatably connected to the fixing frame 11 through a bearing. The second rotating rod 401 is rotatably connected to the connecting plate 306 through a bearing.

[0038] The effect is that the lifting frame 202 moves upward. At this time, the first positioning frame 303 disengages from the dressing. The rack 6 on the first positioning frame 303 approaches the second gear 13 and meshes with it. When the mounting frame 209 continues to move, the second gear 13 rotates by meshing with the rack 6. The support rod 503 drives the control wheel 501 to rotate. At this time, the first gear 506 rotates synchronously with the guide block 505. The first gear 506 on the rotating frame 211 meshes with the incomplete gear 504 on the control wheel 501. At this time, it can drive the first gear 506 to rotate. The rotation of the first gear 506 drives the rotating frame 211 to rotate. The rotation of the rotating frame 211 drives the electric cutting wheel 212 at the bottom to rotate one week. After the rotating frame 211 rotates one week, the abutting block 507 just disengages from the guide block 505. Through the elastic force of the torsion spring, it drives the mounting plate 210 to rotate. The mounting plate 210 drives the rotating frame 211 to deflect. The abutting block 507 contacts the control wheel 501 on one side of the guide block 505. The rotating frame 211 drives the electric cutting wheel 212 at the bottom to deflect. The deflected electric cutting wheel 212 contacts the grinding plate 508 on the first positioning frame 303. Starting the electric cutting wheel 212 can grind it. When the mounting frame 209 continues to move and the control wheel 501 continues to rotate, the abutting block 507 contacts the guide block 505, making the rotating frame 211 gradually vertical. At the same time, the first gear 506 at the top continues to contact and mesh with the incomplete gear 504. At this time, it can drive the electric cutting wheel 212 at the bottom to rotate one week. Repeating the above operations can grind the other side. And a plurality of balls are arranged on the outer surface of the first slide rod 301, and corresponding circular grooves are arranged inside the first slide hole 302. When the first positioning frame 303 leaves the bottom dressing upward, a spring will be generated upward, so that vibrations are generated by the continuous entry and exit of the first slide rod 301 into the circular groove, thereby shaking the debris attached to the grinding plate 508. At the same time, a suction fan is arranged near the bottom inside the first positioning frame 303 to collect the debris.

[0039] Working principle: Place the medical sterile dressing on the conveyor belt 7 on the outer surface of the frame 1. Start the air cylinder 9 to push the lifting frame 202 to a suitable height. At the same time, start the double-headed motor 12. When moving and positioning, the double-headed motor 12 drives the first rotating rod 201 to rotate, and the first swing rod 203 outside the first rotating rod 201 rotates accordingly. Through the first positioning rod 204, it drives the second swing rod 205 to move, so that the slider 207 on the mounting rod 206 slides in the limit chute 208 of the lifting frame 202. During the swinging process of the second swing rod 205, it will drive the symmetrically arranged first positioning rod 204 to move, enabling the slider 207 to slide reciprocally inside the limit chute 208, thereby driving the mounting frame 209, mounting plate 210, rotating frame 211, and electric cutting wheel 212 to move horizontally. The electric cutting wheel 212 cuts the dressing. During the cutting process, the air cylinder 9 drives the electric cutting wheel 212 to gradually descend and reciprocally cut the dressing. During the downward movement of the lifting frame 202, the first slide rod 301 slides in the first slide hole 302, and the first positioning frame 303 presses down under the action of the first spring 304 to preliminarily position the dressing. The connecting plate 306 drives the second slide rod 308 to slide in the second slide hole 307, and the second positioning frame 309 further presses down under the action of the second spring 310 to achieve precise positioning of the dressing, avoiding displacement during the cutting process, resulting in curling or uneven cutting. During the cutting operation, the electric cutting wheel 212 is started to cut the positioned medical sterile dressing. As the cutting wheel rotates, the dressing is gradually cut. While cutting, the double-headed motor 12 drives the second rotating rod 401 to rotate. The second rotating rod 401 is transmitted through the first rotating rod 402 and the second rotating rod 403, and through the limitation of the third rotating rod 408 and the fourth rotating rod 409, it can push the first positioning slider 405 and the second positioning slider 406 to slide in the positioning hole 404, enabling the positioning sleeve 407 provided at the bottom of the first positioning slider 405 to drive the lifting rod 410 to move. At the same time, when the lifting rod 410 moves, the clamping rod 411 at the top of the lifting rod 410 can stably slide inside the guiding groove 412, thereby driving the lifting rod 410 to move up and down inside the positioning sleeve 407 and the first positioning slider 405. When the lifting rod 410 descends, the cutting blade 413 on its lower surface performs a break point treatment on the center of the dressing, forming break points that are convenient for tearing. And multiple cutting blades 413 are provided, which can be cut into cross cuts to facilitate the insertion of the drainage tube of the dressing in the future. Move the lifting frame 202 upward. At this time, the first positioning frame 303 disengages from the dressing, and the rack 6 on the first positioning frame 303 approaches the second gear 13 and meshes with it. When the mounting frame 209 continues to move, the second gear 13 rotates by meshing with the rack 6, and the support rod 503 drives the control wheel 501 to rotate. At this time, the incomplete gear 504 and the guide block 505 rotate synchronously. The first gear 506 on the rotating frame 211 meshes with the incomplete gear 504 on the control wheel 501,At this time, it can drive the first gear 506 to rotate. The rotation of the first gear 506 drives the rotating frame 211 to rotate. The rotation of the rotating frame 211 drives the electric cutting wheel 212 at the bottom to rotate one week. After the rotating frame 211 rotates one week, the abutting block 507 just disengages from the guiding block 505. A torsion spring is arranged between the mounting plate 210 and the mounting frame 209, so that the mounting frame 209 can drive the mounting plate 210 to rotate on the mounting frame 209 under the action of the torsion spring. The abutting block 507 contacts the control wheel 501 on one side of the guiding block 505, and the rotating frame 211 drives the electric cutting wheel 212 at the bottom to deflect. The deflected electric cutting wheel 212 contacts the grinding plate 508 on the first positioning frame 303. Starting the electric cutting wheel 212 can grind it. When the mounting frame 209 continues to move and the control wheel 501 continues to rotate, the abutting block 507 contacts the guiding block 505, making the rotating frame 211 gradually perpendicular. At the same time, the first gear 506 at the top continues to contact and mesh with the incomplete gear 504. At this time, it can drive the electric cutting wheel 212 at the bottom to rotate one week. Repeating the above operations can grind the other side. And a plurality of balls are arranged on the outer surface of the first slide rod 301, and corresponding circular grooves are arranged inside the first slide hole 302, so that when the first positioning frame 303 leaves the bottom patch upward, a spring will be generated upward, so that vibrations are generated by the continuous entry and exit of the first slide rod 301 into the circular groove inside, thereby the debris attached to the grinding plate 508 can be shaken off. At the same time, an exhaust fan is arranged at a position near the bottom inside the first positioning frame 303 to collect the debris.
