Description

Technical Field

[0001] The utility model relates to the technical field of gel patch production, in particular to a coating device for gel patch production. Background Technique

[0002] Gel patches are dressings commonly used for wound care. By vaporizing the moisture and natural cooling components contained in the polymer gel, heat can be taken away to achieve local cooling. The drug components are combined with the hydrogel, and through the hydration effect, the drug components can quickly penetrate the fat layer, penetrate into the subcutaneous tissue, reach the lesion site, act on the affected area, and achieve the effects of cold compress for pain relief, transdermal absorption, and sustained-release drug delivery.

[0003] The gel patch consists of a backing layer, a gel layer, and a non-stick layer. Backing layer: A non-woven fabric that allows air circulation, enabling the gel layer to adhere to it, being breathable but not water-permeable, and supporting heat dissipation. Gel layer: A water-soluble polymer framework structure containing water molecules and drugs, having thermosensitive penetration, membrane-controlled release effects, and moderate viscosity. Non-stick layer: A surface layer of a polyester protective film embossed film layer, which is removed before use. The embossed surface can form patterns on the gel surface, which can not only ensure the skin respiration and metabolism of the application site, but also increase the skin contact area, making the application more secure and the absorption more complete. During the production process of the gel patch, the coating of the gel layer is the most important. The gel is coated on the base cloth through a coating device.

[0004] In the prior art, application number CN202221157901.8 proposed a coating device for medical cold compress patch production. A coating device for medical cold compress patch production includes: an equipment installation table, a material conveyor belt, and an installation gantry. The material conveyor belt is installed on the upper wall surface of the equipment installation table, and the installation gantry is installed at the middle position of the upper wall surface of the equipment installation table. The installation gantry is located outside the material conveyor belt. Two pairs of conveying and pressing structures are installed on the equipment installation table, and a feeding and rotating coating structure is installed on the installation gantry.

[0005] The above patent solves the problems of uneven gel coating and inability to precisely control the gel coating amount. However, during use, after the coating roller coats the gel on the gel patch base cloth, a large amount of gel will adhere to the surface of the coating roller. Therefore, after the coating device stops, the staff needs to clean the gel on the external part of the coating roller. If not cleaned in time, the gel is likely to solidify on the coating roller, which will affect the subsequent coating of the gel after starting the machine. Based on the above problems, a coating device for gel patch production is proposed in this application. Content of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] In a typical implementation manner of this application, refer to Figures 1-4, A smearing device for the production of gel patches, comprising a mounting base 1. A mounting bracket 2 is fixedly arranged on the top of the mounting base 1. A storage box 3 is fixedly arranged on the upper side wall of the mounting bracket 2. The storage box 3 can be replenished with gel through the feed pipe at the top of the storage box 3. A driving motor 4 is fixedly arranged on the front side of the storage box 3. The output end of the driving motor 4 is fixedly provided with a rotating smearing roller 5. A gel cleaning component for facilitating the cleaning of the gel attached to the surface of the rotating smearing roller 5 is arranged inside the mounting bracket 2. The gel cleaning component includes a servo electric cylinder 6 fixedly arranged on the rear side of the mounting bracket 2. The output end of the servo electric cylinder 6 is fixedly provided with a scraping box 7. A guide rod 8 is fixedly arranged on the rear side of the scraping box 7. The guide rod 8 is slidably arranged inside the mounting bracket 2. A gel collection box 9 is slidably arranged inside the scraping box 7. The top of the gel collection box 9 is provided with a feed inclined plane. The outer surface of the gel collection box 9 fits with the inside of the scraping box 7. The gel collection box 9 is made of stainless steel. The feed inclined plane facilitates the gel for scraping to enter the inside of the gel collection box 9, avoiding the gel from accumulating on the top of the gel collection box 9 and causing the gel on the top to fall into the inside of the scraping box 7 when the gel collection box 9 is taken out. Thus, the gel collection box 9 can be completely inserted into the scraping box 7. A locking component is arranged between the gel collection box 9 and the scraping box 7. The locking component includes a rotating shaft 10 rotatably arranged inside the gel collection box 9. A rotating knob 11 is fixedly arranged on the left side of the rotating shaft 10. A rotating plate 12 is fixedly arranged on the surface of the rotating knob 11. A rubber elastic pad 13 is fixedly arranged on the left side of the rotating plate 12. A locking plate 14 is lapped on the surface of the rubber elastic pad 13. The locking plate 14 is in an L-shaped structure. The number of the locking plates 14 is two, and the two locking plates 14 are symmetrically distributed. The locking plate 14 is made of metal material. By means of the cooperation of the two locking plates 14, the two rotating plates 12 and the two rubber elastic pads 13, the rotating plate 12 can be prevented from moving out of the inside of the locking plate 14, so that the position of the gel collection box 9 can be firmly locked. The locking plate 14 is fixedly installed on the left side of the scraping box 7. The servo electric cylinder 6 pushes the scraping box 7 to scrape the gel attached to the rotating smearing roller 5 into the inside of the gel collection box 9. The rotating knob 11 drives the rubber elastic pad 13 to move out of the inside of the locking plate 14 through the rotating plate 12. The gel collection box 9 is taken out of the scraping box 7 and the gel inside is cleaned. Then the cleaned gel collection box 9 is reinserted into the scraping box 7. The rotating knob 11 drives the rubber elastic pad 13 to insert into the inside of the locking plate 14 through the rotating plate 12. The rubber elastic pad 13 deforms and rebounds to fix the rotating plate 12 inside the locking plate 14, thereby locking the gel collection box 9 inside the scraping box 7, facilitating the treatment of the gel attached to the rotating smearing roller 5, avoiding the gel from solidifying on the rotating smearing roller 5, and facilitating the cleaning of the collected gel. A lifting support component for facilitating the support of the gel patch base fabric is arranged below the rotating smearing roller 5. The lifting support component includes a hydraulic push rod 15 fixedly installed on the top of the mounting base 1.The output end of the hydraulic push rod 15 is fixedly provided with a U-shaped mounting plate 16. A support roller 17 is rotatably arranged inside the U-shaped mounting plate 16. The hydraulic push rod 15 drives the support roller 17 to move up or down through the U-shaped mounting plate 16, so as to facilitate the support of the base cloth unrolled from the gel patch base cloth reel 22, avoid the uneven application of the gel and the occurrence of accumulation, and prevent the U-shaped mounting plate 16 and the support roller 17 from blocking the movement of the scraping box 7. In the middle of the top of the mounting base 1, a tension adjusting assembly is provided to facilitate the provision of tension to the gel patch base cloth. On the left side of the top of the mounting base 1, a unwinding assembly is provided to facilitate the unwinding of the gel patch base cloth.

[0029] As a preferred implementation mode in this embodiment, refer to Figure 5 The unwinding assembly includes a mounting vertical plate 18 fixedly installed on the top of the mounting base 1. A rotary motor 19 is fixedly arranged at the rear side of the mounting vertical plate 18. The output end of the rotary motor 19 is fixedly provided with a mounting plate 20. A unwinding shaft 21 is fixedly arranged on the front side of the mounting plate 20. The surface of the unwinding shaft 21 is lapped with a gel patch base cloth reel 22. The number of unwinding shafts 21 is three. The three unwinding shafts 21 are all fixedly installed on the front side of the mounting plate 20 and are distributed in a circular array. Three gel patch base cloth reels 22 can be placed simultaneously through the three unwinding shafts 21. And after the gel patch base cloth reel 22 on one unwinding shaft 21 is used up, the gel patch base cloth reel 22 on another unwinding shaft 21 can be rotated to the unwinding position, and the used-up unwinding shaft 21 can be put into the gel patch base cloth reel 22 again, so as to continuously supply materials to the coating device. A limiting ring 23 is lapped on the front side of the gel patch base cloth reel 22. The limiting ring 23 is threadedly arranged on the surface of the unwinding shaft 21. The output end of the rotary motor 19 drives the mounting plate 20 to rotate. The mounting plate 20 drives the gel patch base cloth reel 22 to move through the unwinding shaft 21 and the limiting ring 23, so as to facilitate the continuous feeding of the coating device, reduce the downtime of the coating device, and avoid wasting too much time in placing the gel patch base cloth reel 22.

[0030] As a preferred implementation mode in this embodiment, refer to Figures 6-7The tension adjustment assembly includes a gantry mounting frame 24 fixedly mounted on the top of the mounting base 1, an electric push rod 25 fixedly arranged on the top of the gantry mounting frame 24, a moving plate 26 fixedly arranged on the output end of the electric push rod 25, a connecting column 27 slidingly arranged inside the moving plate 26, a fixing frame 28 fixedly arranged at the bottom end of the connecting column 27, a pressure sensor 29 overlappedly arranged on the top of the fixing frame 28, two pressure sensors 29 are symmetrically distributed, a detection end of the pressure sensor 29 contacts the top of the fixing frame 28, the pressure sensor 29 is fixedly mounted on the bottom of the moving plate 26, and the fixing frame 28 is internally provided with a connecting column 27 slidingly arranged inside the connecting column 27. A tension roller 30 is rotatably provided, and the output end is driven by the electric push rod 25 to push the movable plate 26 downward, so that the connecting column 27 and the pressure sensor 29 move downward, so that the fixed frame 28 drives the tension roller 30 to move the base cloth downward, and the tension of the base cloth is adjusted. The base cloth will give the tension roller 30 an identical reverse force, so that the tension roller 30 squeezes the detection end of the pressure sensor 29, and the pressure sensor 29 detects the force applied to the base cloth, thereby avoiding wrinkles on the gel application base cloth due to too little force applied, and avoiding breakage of the gel application base cloth due to too much pressure applied.

[0031] The gel patch production application device is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0032] In use: Place the gel patch base fabric reel 22 on the unwinding reel 21, screw the limit ring 23 onto the surface of the unwinding reel 21 to limit the gel patch base fabric reel 22. Pass the base fabric on the gel patch base fabric reel 22 through the bottom of the tension roller 30, and drive the output end of the electric push rod 25 to push the moving plate 26 downward, so that the connecting column 27 and the pressure sensor 29 move downward, thereby making the fixing frame 28 drive the tension roller 30 to move the base fabric downward to adjust the tension of the base fabric. Then pass the base fabric through between the rotary coating roller 5 and the support roller 17, and drive the output end of the drive motor 4 to drive the rotary coating roller 5 to rotate, and apply the gel in the storage box 3 onto the base fabric. When it is necessary to clean the rotary coating roller 5, the servo electric cylinder 6 drives the output end to push the scraping box 7 forward, and scrapes the gel attached to the rotary coating roller 5 into its interior through the rear side of the scraping box 7 and into the gel collection box 9. When the cleaning of the part of the rotary coating roller 5 located in the external environment is completed, the servo electric cylinder 6 drives the output end to drive the scraping box 7 to reset. Rotate the rotary knob 11 to drive the rotating shaft 10 to rotate inside the gel collection box 9, so that the rotating plate 12 drives the rubber elastic pad 13 to move out of the locking plate 14. The rotary knob 11 takes out the gel collection box 9 from the scraping box 7 through the rotating shaft 10 and conducts cleaning. Then reinsert the cleaned gel collection box 9 into the scraping box 7, and rotate the rotary knob 11 again, so that the rotating plate 12 drives the rubber elastic pad 13 to insert into the locking plate 14, so that the inner wall of the locking plate 14 squeezes the rubber elastic pad 13, and the rubber elastic pad 13 deforms and rebounds to fix the rotating plate 12 inside the locking plate 14, and the position of the rotary knob 11 can be locked, thereby locking the gel collection box 9 inside the scraping box 7.
