Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical packaging device manufacturing, and in particular to a uniform coating device for producing medical coated paper. Background Technology
[0002] Coated paper is a special type of processed paper. Water-based adhesives, hot melt adhesives, or other adhesives are evenly coated on its surface using methods such as roller coating or scraping. Then, through curing processes such as drying, cooling, or chemical cross-linking, the adhesives are bonded to the paper to form a whole, ultimately creating a special type of paper with peelable or permanent adhesive properties. Its adhesive strength and applicable scenarios can be adjusted by changing the type of adhesive, coating thickness, and curing method.
[0003] Traditional adhesive coating production methods suffer from uneven coating and adhesive waste. The uniformity of the coated paper directly affects the product's performance and safety. Only by ensuring uniform adhesive coating can the stable release and penetration of drugs be guaranteed, creating an ideal environment for wound healing. Therefore, a uniform coating device for medical adhesive paper production is proposed to solve the above problems. Utility Model Content

[0023] 1. In this utility model, the glue coating mechanism opens the valve to spray water-based glue onto the adhesive paper through the conveying pipe. Then, the first motor drives the gear to rotate, thereby moving the lifting column and adjusting the distance between the brush and the adhesive paper. The first spring adjusts the brush and the paper to make them elastically contact and tightly adhere for coating. The conveyor belt drives the adhesive paper, and the brush initially coats the adhesive paper evenly, suitable for paper of different thicknesses. The second motor drives the second glue roller to rotate, and the driving wheel drives the driven wheel to rotate, causing the first glue roller to rotate. The rotation of the two glue rollers presses the adhesive paper to ensure uniform glue coating.
[0024] 2. In this utility model, excess glue squeezed out by the two glue rollers drips into the glue collection box. When the glue collection box needs to be cleaned, the lever is pulled down to slide the locking head into the shelf, and the glue collection box can be taken out. The glue in the glue collection box is then transferred to the glue bucket for reuse to avoid glue waste and to clean the box. When putting the glue collection box back in, the lever is pulled down again to slide the locking head down until the entire glue collection box passes the locking head. Due to the action of the second spring, the locking head rebounds, thus fixing the glue collection box. This solves the problem of collecting excess glue, facilitates glue collection and disposal, and solves the problem of fixing the glue collection box. Attached Figure Description

The gear 25 and the rack 24 mesh with each other. A glue inlet is provided on the top of the glue tank 8. The end of the glue delivery pipe 5 away from the glue tank 8 is located directly above the conveyor belt 11. A valve 6 is installed inside the glue delivery pipe 5. One end of the first spring 26 is fixedly connected to the top of the brush 27, and the end of the first spring 26 away from the brush 27 abuts against the inner top wall of the housing 15.
[0036] The platform 2 is used to fix and support the entire equipment; the conveyor 3 is used to fix and support the glue application mechanism and the conveyor belt 11; the conveyor belt 11 is used to transport the adhesive paper to the glue application area; the load-bearing plate 18 is used to fix and connect various parts; the fixing plate 12 is used to install the first motor 13, which provides power for the lifting and lowering of the glue application mechanism; the rotating column 14 drives and supports the gear 25; the gear 25 and the rack 24 cooperate to control the lifting column 10 to lift and lower; the lifting column 10 is used to fix various parts; the glue bucket 8 is used to hold glue; the connecting column 7 is used to fix the outer shell 15 and support the internal parts of the outer shell 15; the outer shell 15 is used to fix the wool.

Valve 6 controls the flow of glue from glue delivery pipe 5. First spring 26 fixes the inside of outer shell 15 to brush 27, making brush 27 tightly and elastically contact the paper surface. Second motor 23 drives drive wheel 22 to rotate, which in turn drives driven wheel 21 to rotate synchronously. The meshing interaction between drive wheel 22 and driven wheel 21 drives first glue roller 16 and second glue roller 17 to rotate synchronously. The rotation of the two glue rollers interacts to press the adhesive onto the paper, making the glue coating more even.
[0037] Reference Figure 1 , Figure 2 and Figure 6The glue collection mechanism includes a glue collection box 19 and a fixed shell 20. The glue collection box 19 is located above the platform 2. The fixed shell 20 is fixedly connected to the bottom of the platform 2. A pull rod 9 is slidably connected inside the fixed shell 20. A second spring 29 is sleeved on the outside of the pull rod 9. A lock head 1 is fixedly connected to the top of the pull rod 9. A wrench 28 is rotatably connected to the bottom of the pull rod 9. The glue collection box 19 is slidably connected between two load-bearing plates 18. A pull ring is fixedly connected to the outside of the glue collection box 19. The lock head 1 is slidably connected to the inside of the platform 2 and passes through the top of the platform 2. The lock head 1 is slidably connected to the inside of the fixed shell 20. The surface of the wrench 28 that contacts the fixed shell 20 is a rounded surface.
[0038] The glue collection box 19 is used to collect the excess glue squeezed out by the two glue rollers and transport the glue through the glue inlet to the glue bucket 8 for reuse and cleaning. The lock head 1 is used to fix the glue collection box 19. The wrench 28 is used to pull the lock head 1 to fix the wrench 28 when the glue collection box 19 needs to be cleaned. The lever 9 is used to pull the lock head 1 to fix the wrench 28. The wrench 28 interacts with the fixing shell 20 to drive the lever 9 to slide downward, so that the lock head 1 is submerged in the shelf 2. The second spring 29 makes the lock head 1 firmly fix the glue collection box 19 when there is no external force. This solves the problem of collecting excess glue, facilitates glue collection and disposal, and avoids glue waste.
[0039] Working principle: During the production of medical coated paper, the coated paper is placed on the conveyor belt 11. The first motor 13 is started, driving the rotating column 14 to rotate. The gear 25 on the outside of the rotating column 14 rotates accordingly. Through meshing with the rack 24, the lifting column 10 slides up and down along the inside of the hollow column 4 to adjust the height of the glue tank 8 and the brush 27 to accommodate different paper thicknesses. After adjusting the height, the valve 6 inside the glue delivery pipe 5 is opened, and the glue in the glue tank 8 flows through the glue delivery pipe 5 to the coated paper. Due to the elastic contact of the brush 27 inside the outer shell 15 with the paper surface under the action of the first spring 26, the brush 27 evenly applies the glue to the paper as the paper moves under the drive of the conveyor belt 11, achieving uniform coating. At the same time, the second motor 23 is started, driving the drive wheel 22 to rotate. Through the meshing of the drive wheel 22 and the driven wheel 21, the drive wheel 22 rotates, driving the paper to rotate. The first and second glue rollers 16 and 17 rotate synchronously. The rotation of the two rollers presses the glue onto the paper, making the glue application more even. Excess glue squeezed out by the two rollers drips into the glue collection box 19. When the glue collection box 19 needs to be cleaned, the wrench 28 is pulled. The side of the wrench 28 that intersects with the fixed shell 20 is rounded. As the wrench 28 rotates with the rounded surface, it interacts with the fixed shell 20, causing the pull rod 9 to slide downwards, so that the locking head 1 is inserted into the shelf 2. The glue collection box 19 can then be taken out, and the glue can be transferred to the glue bucket 8 through the glue inlet for reuse and cleaning. When putting the glue collection box 19 back in, the wrench 28 is pulled again, causing the pull rod 9 to slide upwards, so that the locking head 1 is fixed on the outside of the glue collection box 19. When no external force is applied, the locking head 1 firmly fixes the glue collection box 19, solving the problem of collecting excess glue, facilitating glue collection and disposal, and avoiding glue waste.
