Description

Technical Field

[0001] The present disclosure relates to the technical field of surgical towel production equipment, and in particular to an integrated coating and compounding device for surgical towels. Background Art

[0002] Surgical drapes are key medical consumables used to cover the patient's incision area during surgery. Their main function is to isolate contamination sources and prevent cross-infection during surgery. With the improvement of medical protection standards, modern high-performance antibacterial surgical drapes are generally coated with an antibacterial pressure-sensitive adhesive layer on the surface of their flexible substrate to achieve good adhesion and sustained antibacterial effect. This type of product must meet the following key performance indicators in clinical applications: (1) The coating thickness control accuracy is within ±5μm to ensure coating uniformity and curing consistency; (2) The antibacterial agent activity retention rate is greater than 95% to ensure that the antibacterial efficacy is not attenuated during the processing process; (3) The composite fastness is greater than 2N / cm to ensure good bonding strength and interface stability between the protective film and the substrate.

[0003] At present, the mainstream production processes at home and abroad are mainly divided into the following two categories: 1. Large roller coating production line, this type of system usually consists of multi-stage precision coating machine (such as slot coating head), tunnel oven (length > 10 meters) and hot pressing laminating equipment, suitable for large-scale continuous production (capacity > 1000 m 2 / h). Although this type of production line has high production efficiency and automation level, it has the following significant limitations: (1) The minimum feed volume requirement is high (generally ≥500 m 2 ), which cannot meet the needs of new product development and small-batch trial production; (2) The equipment investment is large and the debugging cycle is long, making it difficult to flexibly respond to process adjustments; (3) It has high requirements for the consistency of raw material batches and is easily affected by fluctuations in incoming materials and affect product quality; (4) It has high energy consumption and complex cleaning and maintenance, which is not conducive to use by small and medium-sized enterprises.

[0004] 2. Manual laboratory preparation method, using a scraper coater, an independent oven and a manual pressing device for small-scale trial production, relying on the operator's experience to adjust parameters. Although this method can achieve the preparation of a small number of samples, it has the following significant limitations: (1) The coating thickness control accuracy is poor (fluctuation can reach ±20μm), resulting in poor curing in local over-thick areas (curing degree drops by more than 40%), affecting the antibacterial performance; (2) The antimicrobial agent is unevenly distributed, with an edge concentration deviation of more than 15%, posing a migration risk; (3) The manual pressing pressure is unstable, the composite interface bubble rate is high, the peel strength dispersion coefficient is large, and the finished product quality is uncontrollable; (4) The oven temperature control accuracy is low (only ±5℃), and gradient heating drying / curing cannot be achieved, which easily causes problems such as surface crusting and volatile matter retention in the inner layer; (5) The overall process controllability is poor and the repeatability is low, which seriously affects product development efficiency and data accumulation.

[0030] As an implementation method, Figures 2 to 4As shown, the coating mechanism 20 includes a first chassis 21, a glue box 22 and a first pressing assembly 23, the first pressing assembly 23 includes a first mounting frame, a first pressing roller group 232 and a first adjusting assembly, the composite mechanism 40 includes a second chassis 41 and a second pressing assembly 42, the second pressing assembly 42 includes a second mounting frame, a second pressing roller group 422 and a second adjusting assembly, the first unwinding assembly 11 includes a first unwinding bracket 111 and a first unwinding roller 112, the first unwinding bracket 111 is arranged on the first chassis 21, the first unwinding roller 112 is rotatably arranged on the first unwinding bracket 111, the first unwinding roller 112 is sleeved with a base film 60, and the first mounting frame is provided. The first base frame 21 is placed on the first base frame 21, and the glue box 22 is installed on the first mounting frame. The glue box 22 has a accommodating cavity 221 with an upward opening. The accommodating cavity 221 is used to accommodate pressure-sensitive adhesive. A first base film inlet 222 and a first base film outlet 223 are respectively formed on the opposite side walls of the accommodating cavity 221. The first base film inlet 222 and the first base film outlet 223 are both connected to the accommodating cavity 221. The first pressing roller group 232 includes a first pressing roller 2321 and a second pressing roller 2322 arranged opposite to each other in an upper and lower direction. The first pressing roller 2321 is rotatably and movably connected to the first mounting frame, and the second pressing roller 2322 is rotatably connected to the first mounting frame. The first pressing roller 2321 and the second pressing roller 2322 are rotatably connected to the first mounting frame. There is a pressing gap 2323 between 322 for pressing the pressure-sensitive adhesive on the base film 60, the first adjustment component is arranged on the first mounting frame, the first adjustment component is used to adjust the moving distance of the first pressure roller 2321 to change the size of the pressing gap 2323, the second unwinding component 12 includes a second unwinding bracket 121 and a second unwinding roller 122, the second unwinding bracket 121 is arranged on the second base frame 41, the second unwinding roller 122 is rotatably arranged on the first unwinding bracket 111, the second unwinding roller 122 is provided with a protective film 61, the second mounting frames are all arranged on the second base frame 41, the second pressure roller group 422 includes a third pressure roller 422 arranged oppositely to each other. 221 and the fourth pressing roller 4222, the third pressing roller 4221 is rotatably and movably connected to the second mounting frame, the fourth pressing roller 4222 is rotatably connected to the second mounting frame, and there is a composite gap 4223 between the third pressing roller 4221 and the fourth pressing roller 4222 for pressing the protective film 61 on the side of the pressure-sensitive adhesive away from the base film 60, the second adjusting component is arranged on the second mounting frame, the second adjusting component is used to adjust the moving distance of the third pressing roller 4221 to change the size of the composite gap 4223, the winding mechanism 50 includes a winding bracket 51 and a winding roller 52, the winding bracket 51 is provided with a motor (not shown), and the winding roller 52 is connected to the motor.

[0031] The first base film outlet 223 and the pressing gap 2323 are aligned and connected.

[0032] The first adjusting component is used to adjust the distance between the first pressing roller 2321 and the second pressing roller 2322 , that is, to adjust the size of the pressing gap 2323 .

[0033] The second adjusting component is used to adjust the distance between the third pressing roller 4221 and the fourth pressing roller 4222 , that is, to adjust the size of the composite gap 4223 .

[0034] The adhesive box 22 has an upwardly opening housing 221 for storing the pressure-sensitive adhesive required during the production process. Opposite side walls of the housing 221 are formed with a first base film inlet 222 and a first base film outlet 223, respectively, to facilitate smooth passage of the base film 60 through the adhesive box 22.

[0035] The preparation process can be as follows: before coating, the base film 60 unwound by the first unwinding component 11 can pass through the accommodating cavity 221 of the glue box 22 through the first base film inlet 222 and the first base film outlet 223, and then pass through the pressing gap 2323 of the coating mechanism 20, and then pass out from the composite gap 4223 of the composite mechanism 40, and be rewound by the rewinding mechanism 50.

[0036] The coating process can be as follows: After the preparatory work is completed, the pressure-sensitive adhesive can be placed through the opening onto the portion of the base film 60 located in the accommodating cavity 221 of the adhesive box 22. The reeling mechanism 50 is then activated, allowing the base film 60 to move forward under the traction of the reeling mechanism 50. In this way, the portion of the base film 60 coated with the pressure-sensitive adhesive can enter the pressing gap 2323 (a controllable narrow gap formed between the first pressing roller 2321 (adjustable) and the second pressing roller 2322 (fixed)). A portion of the pressure-sensitive adhesive is sheared and squeezed here, thereby being evenly pressed onto the surface of the base film 60 and forming a pressure-sensitive adhesive layer. The remaining portion of the pressure-sensitive adhesive (the excess pressure-sensitive adhesive) is squeezed back into the adhesive box 22 and is used for the initial coating of the newly entered base film 60 section. That is, as the base film 60 continues to advance, new uncoated sections can continue to enter the glue box 22, the glued sections are pressed, and the excess pressure-sensitive adhesive is retained in the glue box 22 to provide initial coating material for the newly entered uncoated sections. With this arrangement, the device disclosed can form a self-sufficient dynamic coating cycle mechanism, which can realize the integrated operation of coating and pressing at the same time, thereby improving the coating work efficiency and reducing resource waste. The lamination process can be as follows: After the glue-coated base film 60 has been sequentially pressed by the coating mechanism 20 and dried and cured by the drying mechanism 30, it continues forward to the laminating mechanism 40 under the traction of the rewinding mechanism 50. At this point, the second unwinding assembly 12 unwinds the protective film 61, allowing the protective film 61 to adhere to the base film 60 due to the adhesion of the pressure-sensitive adhesive layer. This allows the protective film 61 and base film 60 to achieve a preliminary lamination before the lamination gap 4223. This allows the protective film 61 to advance synchronously with the glue-coated base film 60 and enter the lamination gap 4223 (the controllable narrow gap formed between the third pressure roller 4221 (adjustable) and the fourth pressure roller 4222 (fixed)). Finally, the protective film 61 and the glue-coated base film 60 are subjected to constant pressure from the second pressure roller assembly 422, which eliminates air bubbles and improves lamination strength.

[0037] The winding process of the composite film 62 may be as follows: the composite double-layer film passes through the composite gap 4223 and is finally wound up by the winding mechanism 50 .

[0038] Optionally, the first pressing roller 2321 and the second pressing roller 2322 are both constructed as high-precision stainless steel mirror rollers. With this arrangement, on the one hand, the surface of the high-precision stainless steel mirror rollers is extremely smooth and flat, which can apply uniform pressure to the base film 60 during the lamination process, helping to achieve a more uniform pressure-sensitive adhesive coating. In addition, the smooth surface can reduce defects or irregularities in the coating, such as bubbles, streaks, etc., thereby improving the quality of the coating. On the other hand, stainless steel has good corrosion resistance and wear resistance, and is particularly suitable for working environments that require long-term contact with chemicals (such as pressure-sensitive adhesives). This not only extends the service life of the equipment, but also reduces maintenance costs. In addition, the stainless steel surface is easy to clean and is not prone to residual contaminants such as pressure-sensitive adhesives, which is particularly important for maintaining sanitary conditions on the production line, especially when producing medical materials.

The two ends of the second pressing roller 2322 are rotatably connected to the two first fixed blocks 2331, the second mounting frame includes two second brackets 421, the second adjustment assembly includes two second adjustment members 423, each second bracket 421 is provided with a second adjustment member 423, the second adjustment member 423 includes a second fixed block 4231, a second sliding block 4232 and a second adjusting screw 4233, the two second brackets 421 are arranged opposite to each other and connected to the second base frame 41, and a second slide rail groove 4211 is formed on the second bracket 421, which passes through the second bracket 421, and the second slide rail groove 4211 extends in the up and down direction. The two opposite side walls of the second slide rail groove 4211 are respectively formed with a second slide rail extending in the up and down direction. The second sliding groove 4212 is extended, and second sliding blocks 4232 are respectively provided with second sliding blocks on opposite sides. The second sliding blocks slidably fit in the second sliding groove 4212. The second fixed block 4231 is provided at the bottom of the second sliding groove 4211. The second adjusting screw 4233 is vertically provided. A second threaded hole is formed on the second sliding block 4232. The second threaded hole passes through the second sliding block 4232 in the up and down direction. The second adjusting screw 4233 is passed through the second threaded hole, and the lower end of the second adjusting screw 4233 is rotatably connected to the top of the second fixed block 4231. The second sliding block 4232 is threadedly connected to the second adjusting screw 4233 through the second threaded hole. The third pressing roller 4221 is located between the two second sliding blocks 4232.The two ends of the third pressing roller 4221 are rotatably connected to the two second sliding blocks 4232 , and the fourth pressing roller 4222 is located between the two second fixed blocks 4231 , and the two ends of the fourth pressing roller 4222 are rotatably connected to the two second fixed blocks 4231 .

[0040] When the first adjusting screw 2333 is rotated, the first sliding block 2332 is connected to the screw of the first adjusting screw 2333 via the first threaded hole, so the first sliding block 2332 can move up and down along the direction of the screw. In this way, the position of the first sliding block 2332 can be precisely controlled, thereby changing the height of the first pressing roller 2321 relative to the second pressing roller 2322, and further adjusting the size of the pressing gap 2323 formed between the two, thereby achieving precise control of the coating thickness.

[0041] When the second adjusting screw 4233 is rotated, the second sliding block 4232 moves up and down along the direction of the second adjusting screw 4233. This causes the height position of the third pressing roller 4221 relative to the fourth pressing roller 4222 to change, thereby adjusting the size of the composite gap 4223 formed therebetween. This allows the protective film 61 and the base film 60 to be composited with appropriate pressure, preventing the formation of bubbles and improving composite strength.

[0042] Optionally, the first adjusting screw 2333 and the second adjusting screw 4233 may be operated manually or electrically.

[0043] For the embodiment adopting manual operation mode, Figures 2 to 4 As shown, the upper end of the first adjusting screw 2333 passes through the first threaded hole and forms a first operating part 2334 for operating the rotation of the first adjusting screw 2333, and the upper end of the second adjusting screw 4233 passes through the second threaded hole and forms a second operating part 4234 for operating the rotation of the second adjusting screw 4233.

[0044] For the embodiment adopting electric operation, the first adjusting member 233 also includes a first driving member installed on the first bracket 231, and the second adjusting member 423 also includes a second driving member installed on the second bracket 421. The upper end of the first adjusting screw 2333 passes through the first threaded hole and is connected to the first driving member, and the upper end of the second adjusting screw 4233 passes through the second threaded hole and is connected to the second driving member.

[0045] As an implementation method, Figures 1 to 4As shown, the integrated coating composite device for surgical towels also includes a first detection component 70 and a second detection component 71. The first detection component 70 is arranged on the first mounting frame, and the first detection component 70 is used to detect the moving distance of the first pressure roller 2321. The second detection component 71 is arranged on the second mounting frame, and the second detection component 71 is used to detect the moving distance of the third pressure roller 4221.

[0046] The first detection assembly 70 is used to detect the movement distance of the first pressure roller 2321, thereby monitoring and providing feedback on changes in the lamination gap 2323 in real time. Through the coordination between the first detection assembly 70 and the first adjustment assembly, a worker can adjust the height of the first pressure roller 2321 based on the detection data provided by the first detection assembly 70 and promptly manipulate the first adjustment screw 2333 to ensure that the lamination gap 2323 remains within a set range. Alternatively, the first detection assembly 70 can monitor the actual position of the first pressure roller 2321 in real time and provide feedback to the control system described below. If a deviation is detected, the control system can automatically adjust the position of the first pressure roller 2321 by driving the first drive member in the first adjustment assembly, ensuring that the lamination gap 2323 remains within a set range. This allows for control of the pressure-sensitive adhesive coating thickness to a precision of ±3μm, with a coating thickness coefficient of variation (CV value) of less than 5%, ensuring high coating uniformity and stability.

[0047] Among them, the second detection component 71 is used to detect the moving distance of the third pressure roller 4221, so as to monitor and feedback the changes in the composite gap 4223 in real time. Through the cooperation between the second detection component 71 and the second adjustment component, the staff can adjust the height of the third pressure roller 4221 according to the detection data fed back by the second detection component 71 and timely manipulate the second adjustment screw 4233, so that the composite gap 4223 is always within the set range. Alternatively, the second detection component 71 can monitor the actual position of the third pressure roller 4221 in real time and feed back the data to the control system described below. If a deviation is detected, the control system can automatically adjust the position of the third pressure roller 4221 by driving the second drive member in the second adjustment component, so that the composite gap 4223 is always within the set range. In this way, the composite fastness between the base film 60 and the protective film 61 of the glue-coated section can always be greater than 2N / cm, which is beneficial to improving the overall performance and consistency of the product.

[0048] For the embodiment adopting the electric operation mode, the device of the present disclosure may further include a control system, and the first driving member, the second driving member, the first detection component 70, and the second detection component 71 are electrically connected to the control system.

Each first bracket 231 is provided with a first thickness gauge 701, and the side heads of the two first thickness gauges 701 are respectively used to overlap the side walls at both ends of the first pressure roller 2321, so that the two first thickness gauges 701 can respectively detect the moving distances at both ends of the first pressure roller 2321, and each second bracket 421 is provided with a second thickness gauge 711, and the side heads of the two second thickness gauges 711 are respectively used to overlap the side walls at both ends of the third pressure roller 4221, so that the two second thickness gauges 711 can respectively detect the moving distances at both ends of the third pressure roller 4221.

[0050] Optionally, the first thickness gauge 701 and the second thickness gauge 711 may both be micrometers (resolution 1 μm), laser displacement sensors, or grating rulers, which is not limited in the present disclosure.

[0051] As an implementation method, Figures 2 to 3 As shown, the glue box 22 includes a bottom plate 224 and a partition frame 225. The bottom plate 224 is arranged on a side of the first mounting frame close to the first unwinding assembly 11. The partition frame 225 is arranged to be able to overlap the top surface of the bottom plate 224 and together with the bottom plate 224 define a accommodating cavity 221.

[0052] The detachable partition frame 225 makes the interior of the glue box 22 easy to clean, reduces the impact of residual glue on subsequent production, and also facilitates regular maintenance and inspection.

[0053] As an implementation method, Figure 3 As shown, the partition frame 225 includes a partition 2251 and two side plates 2252. A notch portion is formed on the partition 2251, and the notch portion is configured to jointly define the first base membrane inlet 222 with the bottom plate 224. The two side plates 2252 are arranged opposite to each other and are both connected to the side of the partition 2251 close to the first pressing assembly 23. The two side plates 2252, the partition 2251 and the bottom plate 224 jointly define the accommodating cavity 221, wherein each side plate 2252 is formed with an avoidance portion 2253 on one end close to the first pressing assembly 23 for avoiding the first pressing roller group 232.

[0054] The avoidance portion 2253 is used to avoid the first pressing roller set 232 to prevent mechanical interference, which is beneficial for the base film 60 to smoothly transition to the pressing gap 2323 .

A second base film inlet 312 and a second base film outlet 313 are formed on the box body 31. The second base film inlet 312 and the second base film outlet 313 are both connected to the heating cavity 311. A heating device 32 is arranged on the cavity wall of the heating cavity 311. There are multiple heating devices 32. The multiple heating devices 32 are arranged at intervals along the extension direction of the base film 60 conveying path in the box body 31 and constitute two parallel heating device 32 groups. Among them, along the direction from the second base film inlet 312 to the second base film outlet 313, the heating temperature of the heating device 32 in each heating device 32 group shows an increasing trend.

[0056] It should be noted that if Figure 1 and Figure 2 As shown, the box body 31 is closed, and in order to show the internal structure of the box body 31, only the frame of the box body 31 is shown.

[0058] Optionally, the first temperature zone (temperature range is 65-75° C.) is used to preliminarily heat the base film 60 and the pressure-sensitive adhesive layer, so that the surface of the adhesive layer begins to dry slowly, releasing volatile solvents, and avoiding rapid skinning of the surface layer.

[0059] The first temperature zone (temperature range is 80~95°C) is used to further increase the temperature, promote the gradual volatilization of intermediate volatile components such as inorganic substances in the adhesive layer, and enhance the density of the adhesive layer.

[0060] The first temperature zone (temperature range of 100~120°C) is used for final curing to ensure that the pressure-sensitive adhesive layer is dry and forms a stable structure.

[0061] As an implementation method, Figures 1 to 2 As shown, the integrated coating and compounding device for surgical towels also includes a guide roller 80, and guide rollers 80 are arranged between the first unwinding component 11 and the coating mechanism 20, between the coating mechanism 20 and the drying mechanism 30, between the drying mechanism 30 and the second unwinding component 12, between the second unwinding component 12 and the compounding mechanism 40, and between the compounding mechanism 40 and the winding mechanism 50.

[0062] The guide roller 80 can effectively guide the film material (base film 60 or composite film 62) to smoothly transition between the various process modules, reduce the tension fluctuation of the film material during operation, prevent the film material from deviating, and improve processing consistency.
