Abstract
Description
Technical Field
[0001] This utility model relates to the field of fever-reducing patch production and processing technology, specifically a fever-reducing patch hydrogel coating and indentation mechanism. Background Technology
[0002] Fever-reducing patches, as a commonly used physical cooling product, are widely used in clinical care and home health care. Their coating substrates include various types such as non-woven fabrics, cotton materials, and plastic films. Different materials meet diverse usage needs with their unique breathability, softness, and waterproof properties. In the production process of fever-reducing patches, the uniform coating and indentation of hydrogel are key steps to ensure product quality. The hydrogel is pressed onto the coating substrate by a coating roller to make the hydrogel thickness uniform. Then, the indentation component is used to indent and divide the hydrogel-coated substrate into sections for subsequent cutting and packaging processes.
[0003] In actual production, when the coating roller presses the hydrogel, some hydrogel inevitably adheres to its outer surface. It is necessary to use a scraper to clean the surface. However, the existing cleaning technology has obvious shortcomings. On the one hand, it is difficult for the scraper to maintain continuous contact with the coating roller surface, so the hydrogel adhering to the outer surface of the coating roller cannot be completely scraped off, which will affect the uniformity of subsequent hydrogel coating. On the other hand, there is a lack of effective collection design. The scraped hydrogel is easy to spill and accumulate, which is not convenient for timely collection and cleaning.
[0004] Therefore, a hydrogel coating and indentation mechanism for fever-reducing patches is needed to solve the above-mentioned technical problems. Utility Model Content

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

A mounting bracket 1 3 and a mounting bracket 2 4 are fixedly connected to the top of the worktable 1. A scale 9 is installed on one side of both mounting bracket 1 3 and mounting bracket 2 4. A limit assembly 5 is installed on the top of the worktable 1. Four support legs 10 are fixedly connected to the bottom surface of the worktable 1, and a reinforcing plate 11 is fixedly connected between the four support legs 10. The four support legs 10 are installed at the four bottom corners of the worktable 1 to provide support, and the reinforcing plate 11 enhances the stability of the support legs 10.
[0024] The coating assembly 6 is installed inside the mounting frame 3. The coating assembly 6 includes an electric push rod 601, which is mounted on the top of the mounting frame 3. The output end of the electric push rod 601 is fixedly connected to the mounting frame 603. Two limiting slide rods 602 are slidably connected to the top of the mounting frame 3, and the lower ends of the two limiting slide rods 602 are fixedly connected to the upper surface of the mounting frame 603. A coating roller 604 is rotatably connected to the inner wall of the mounting frame 603. A motor 605 is mounted on one side of the mounting frame 603, and the output end of the motor 605 is connected to the coating roller 604.
[0025] A cleaning assembly 7 is installed on the front side of the mounting frame 603. The cleaning assembly 7 includes a collection frame 701, which is fixedly connected to the front side of the mounting frame 603. Three sliding pillars 702 are slidably connected to the top of the collection frame 701. A connecting plate 703 is fixedly connected to the lower end of the three sliding pillars 702. Three springs 704 are fixedly connected between the connecting plate 703 and the inner top wall of the collection frame 701. The three springs 704 are respectively sleeved on the outer surface of the three sliding pillars 702. A scraper 705 is installed on the bottom surface of the connecting plate 703, and the scraper 705 is in contact with the outer surface of the coating roller 604.
[0026] The workbench 1 serves as the basic support structure, with the conveying assembly 2 installed inside for coating transport, providing a continuous and stable supply for subsequent processes. Both mounting frames 3 and 4 are inverted U-shaped frame structures. The scale 9 allows for precise adjustment of the hydrogel coating thickness and indentation depth. The limiting assembly 5 limits the coating to prevent skewing during transport by the conveying assembly 2. The electric push rod 601 in the coating assembly 6 is fixed to the top of mounting frame 3, driving the mounting frame 603 and coating roller 604 to move up and down. Two guide holes are provided on the top of mounting frame 3, with two limiting slide rods 602 slidingly engaging with them to ensure smooth movement of mounting frame 603 and prevent wobbling. When the motor 605 is energized, it drives the coating roller 604 to rotate, pressing the hydrogel and coating together. The mounting frame 603 in the cleaning component 7 is connected to the collection frame 701. The top of the collection frame 701 is machined with three sliding holes, and three sliding posts 702 are adapted to the sliding holes. Three springs 704 are sleeved on the three sliding posts 702. The elastic force of the springs 704 can make the connecting plate 703 drive the scraper 705 to always keep in contact with the surface of the coating roller 604. When the coating roller 604 rotates, the scraper 705 can scrape off the hydrogel adhering to the surface of the coating roller 604 and let it fall into the collection frame 701 for collection.
[0027] A base plate 706 is rotatably connected to the bottom of the collection frame 701. Studs 707 are threaded onto both sides of the base plate 706, and the studs 707 are threaded into the collection frame 701. The base plate 706 can rotate at the bottom of the collection frame 701, and threaded holes are machined on both sides of the base plate 706. The studs 707 pass through the through holes on the side of the collection frame 701 and engage with the threaded holes in the base plate 706 to secure the base plate 706. During normal operation, tightening the studs 707 fixes the base plate 706 to the bottom of the collection frame 701 to collect the hydrogel. For cleaning, unscrew the studs 707, flip the base plate 706 downwards, and pour out the collected hydrogel.
[0028] The limiting component 5 includes a mounting bracket 3 501, which is fixedly connected to the top of the workbench 1. A two-way lead screw 502 is rotatably connected to the inner wall of the mounting bracket 3 501. A bevel gear 1 503 is fixedly connected to the outer surface of the two-way lead screw 502. A rotating rod 504 is rotatably connected to the top of the mounting bracket 3 501. A bevel gear 2 505 is fixedly connected to the lower end of the rotating rod 504. The bevel gear 2 505 meshes with the bevel gear 1 503.
[0029] The bidirectional lead screw 502 is rotatably connected to the mounting bracket 3 501 and can rotate flexibly. The bevel gear 1 503 fixed on the outer surface of the bidirectional lead screw 502 meshes with the bevel gear 2 505 fixedly connected to the lower end of the rotating rod 504. When the handle at the upper end of the rotating rod 504 is rotated, the bidirectional lead screw 502 can be driven to rotate through the meshing transmission between the bevel gear 1 503 and the bevel gear 2 505.
[0030] Two connecting blocks 506 are threadedly connected to the outer surface of the bidirectional lead screw 502. The two connecting blocks 506 are symmetrically distributed on the outer surface of the bidirectional lead screw 502. Two limiting slide rods 507 are fixedly connected to the inner wall of the mounting bracket 501. The two connecting blocks 506 are slidably connected to the outer surfaces of the two limiting slide rods 507. Limiting plates 508 are fixedly connected to the bottom surfaces of the two connecting blocks 506. The outer surface of the bidirectional lead screw 502 is machined with two sections of threads with opposite directions. The two connecting blocks 506 are threadedly connected to these two sections of threads respectively. When the bidirectional lead screw 502 rotates, the two connecting blocks 506 are driven by the threads and, under the limiting and guiding action of the limiting slide rods 507, can move in opposite directions or towards each other along the axial direction of the bidirectional lead screw 502. The limiting plates 508 move with the movement of the connecting blocks 506. The distance between the two limiting plates 508 can be adjusted by rotating the rotating rod 504 to accommodate coatings of different widths and to limit their movement.
[0031] An indentation assembly 8 is installed inside the mounting frame 2 4. The indentation assembly 8 includes an electric push rod 2 801, which is mounted on the top of the mounting frame 2 4. The output end of the electric push rod 2 801 is fixedly connected to the mounting frame 2 803. Two limiting slide rods 3 802 are slidably connected to the top of the mounting frame 2 4, and the lower ends of the two limiting slide rods 3 802 are fixedly connected to the upper surface of the mounting frame 3 501. An indentation roller 804 is rotatably connected to the inner wall of the mounting frame 2 803. A motor 2 805 is mounted on one side of the mounting frame 2 803, and the output end of the motor 2 805 is connected to the indentation roller 804. The electric push rod 2 801 is fixed to the top of the mounting frame 2 4. The two guide holes on the top of the mounting frame 2 4 slide in cooperation with the limiting slide rods 3 802 to ensure smooth lifting and lowering of the mounting frame 2 803. By starting the motor 2 805, the indentation roller 804 can be rotated to indent and divide the hydrogel on the coating into blocks.
[0032] Working principle: During use, according to the coating width, rotate the handle at the upper end of the rotating rod 504 to drive the second bevel gear 505 to rotate. Since the second bevel gear 505 meshes with the first bevel gear 503, it drives the bidirectional lead screw 502 to rotate. Under the restriction of the first limiting slide rod 507, the two connecting blocks 506 slide towards or away from each other along the bidirectional lead screw 502, thereby driving the limiting plate 508 on the bottom surface of the connecting block 506 to move. The distance between the two limiting plates 508 is reasonably adjusted according to the coating width to limit the coating and prevent the conveying component 2 from deviating when conveying the coating. Subsequently, the electric push rod 601 is activated, and through the action of the two limit slide rods 602 and the scale 9, the mounting frame 603 and the coating roller 604 are pushed downwards and moved smoothly to a suitable height. The motor 605 is activated to drive the coating roller 604 to rotate, pressing the hydrogel onto the coating to make the hydrogel thickness uniform. During this process, the cleaning component 7 plays a role. The scraper 705 is elastically connected to the spring 704 and the slide rod 702. Under the action of the spring 704, it continues to be in close contact with the outer surface of the coating roller 604, which can scrape off the hydrogel adhering to the outer surface of the coating roller 604. The scraped hydrogel falls into the bottom plate 706 of the collection frame 701 for collection. Activate the electric push rod 801. Through the action of two limit slide rods 802 and the scale 9, push the mounting frame 803 and the indentation roller 804 downwards smoothly to a suitable height. Motor 805 drives the indentation roller 804 to rotate, indenting and dividing the coated hydrogel into sections for subsequent cutting and encapsulation. When it is necessary to clean the hydrogel in the collection frame 701, rotate the stud 707 to separate it from the collection frame 701. The base plate 706 loses its fixation, and rotating the base plate 706 downwards allows the collected hydrogel to be removed for cleaning.
[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
