Description

Technical Field

[0001] This utility model relates to the field of health care patch production technology, and in particular to a mechanism for spreading medicine evenly on the surface of a health care patch. Background Technology

[0002] Health patches are topical patch products made by mixing drugs or health-promoting ingredients with a polymer matrix and then coating it onto a backing material. They are applied locally or systemically through skin penetration and are widely used due to their convenience and long-lasting effects. In their production process, evenly coating the ointment-like drug onto the surface of the backing material is a crucial step in ensuring accurate dosage and stable efficacy.

[0003] Currently, this coating process largely relies on manual labor, where workers use tools such as scrapers to apply the coating evenly based on their experience. This manual method has the following drawbacks: 1. It is difficult to guarantee the absolute uniformity of the drug coating on each patch. Differences in thickness and density exist between different batches and even within the same batch, directly affecting the uniformity of efficacy; 2. Production efficiency is low, labor intensity is high, and it cannot meet the needs of large-scale production; 3. Precise thickness control is impossible. When product requirements change and different coating thicknesses are needed, there is a lack of effective adjustment methods, resulting in poor process adaptability. Utility Model Content

[0004] In view of the above situation and in order to make up for the shortcomings of the existing technology, the purpose of this utility model is to provide a mechanism for spreading medicine evenly on the surface of health care patches, which effectively solves the problems of time-consuming and laborious manual operation of spreading medicine evenly and inconvenience in adjusting the spreading thickness.

[0005] The technical solution is as follows: This utility model includes a fixed ring with upper and lower axial directions. Sliding cylinders are respectively provided on the front and rear sides of the upper end of the fixed ring. Telescopic blocks are slidably connected inside the sliding cylinders.

A rotatable rotating post is coaxially provided at the lower end of the connecting post. A coating disk is coaxially provided at the lower end of the rotating post. A limiting plate located below the telescopic block and in contact with the telescopic block is slidably connected inside the sliding cylinder on the front side. A stud rotatably connected to the upper end of the fixed ring with the upper and lower axial directions and threadedly connected to the limiting plate is rotatably connected.

[0006] Preferably, a knob is coaxially provided on the upper end of the stud.

[0007] Preferably, a groove is provided on the left side of the front sliding cylinder, and the limiting plate can slide within the groove.

[0008] Preferably, the front sliding cylinder has an observation groove at its front end, the front end of the limiting plate has an indicator rod located in the observation groove, and the front sliding cylinder has scale lines that cooperate with the indicator rod.

[0009] Preferably, the upper left and right sides of the fixed ring are respectively provided with reset cylinders with upper and lower axial directions, and the bottom surface of the reset cylinder is slidably connected to a reset post by a spring. The left and right ends of the connecting plate are respectively provided with reset plates that are fixed to the reset posts on the corresponding sides.

[0010] Preferably, the rotating column and the connecting column are coaxially and fixedly connected, and a motor is installed inside the connecting column, with the motor output shaft coaxially and fixedly connected to the rotating column.

[0011] Preferably, the upper end of the connecting plate is provided with a gripping ball.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the implementations of the base model disclosed below.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Depend on Figures 1 to 5 The device includes a fixed ring 1 with vertical axial alignment. Sliding cylinders 2 are provided on the front and rear sides of the upper end of the fixed ring 1. Telescopic blocks 3 are slidably connected inside the sliding cylinders 2. The upper ends of the two telescopic blocks 3 are connected by a connecting plate 4. The lower end of the connecting plate 4 is provided with a connecting post 5 coaxial with the fixed ring 1. The lower end of the connecting post 5 is provided with a rotatable rotating post 6 coaxially. The lower end of the rotating post 6 is provided with a coating plate 7 coaxially. A limiting plate 8 located below the telescopic block 3 and in contact with the telescopic block 3 is slidably connected inside the sliding cylinder 2 on the front side. A stud 9 with vertical axial alignment and threaded connection to the limiting plate 8 is rotatably connected to the upper end of the fixed ring 1.

[0024] To facilitate the rotation of the stud 9, a knob 10 is coaxially provided on the upper end of the stud 9.

[0025] To facilitate the movement of the limiting plate 8, a sliding groove 11 is provided on the left side of the front sliding cylinder 2, and the limiting plate 8 can slide within the sliding groove 11.

[0026] To facilitate precise thickness control, the front sliding cylinder 2 has an observation groove at its front end, the front end of the limiting plate 8 has an indicator rod 12 located in the observation groove, and the front sliding cylinder 2 has a scale line 13 that cooperates with the indicator rod 12.

[0027] To facilitate the resetting of the coating plate 7, the upper left and right sides of the fixed ring 1 are respectively provided with resetting cylinders 14 with vertical axial direction. The bottom surface of the resetting cylinder 14 is slidably connected to the resetting column 16 via the spring 15. The left and right ends of the connecting plate 4 are respectively provided with resetting plates 17 that are fixed to the resetting column 16 on the corresponding side.

[0028] In order to make the rotating column 6 rotate, the rotating column 6 is coaxially and fixedly connected to the connecting column 5. The connecting column 5 is equipped with a motor 18, and the output shaft of the motor 18 is coaxially and fixedly connected to the rotating column 6.

[0029] For ease of gripping, the upper end of the connecting plate 4 is provided with a gripping ball 19.

[0030] To enhance the fixing effect, the lower end of the fixing ring 1 is provided with a rubber layer.

[0031] When using this utility model, the operator first holds the holding ball 19 at the upper end of the connecting plate 4 and places the entire device above the backing material that has been coated with ointment. The fixing ring 1 presses the backing material to fix and limit the backing material, preventing it from moving during the spreading process. The screw 9 is driven to rotate by rotating the knob 10 at the upper end of the front sliding cylinder 2. Since the screw 9 and the limiting plate 8 are threadedly connected, the rotation action is converted into the vertical movement of the limiting plate 8 in the sliding cylinder 2. The operator can observe the position of the indicator rod 12 at the front end of the limiting plate 8 in the observation groove of the front sliding cylinder 2, and combine it with the scale line 13 on the cylinder to accurately control the descent height of the limiting plate 8, thereby setting the final pressing position of the application plate 7, i.e. the thickness of the drug application. After adjustment, apply downward pressure to the holding ball 19 to push the connecting plate 4 downward against the resistance of the spring 15 inside the reset cylinder 14. The connecting plate 4 drives the rotating column 6 and the application disk 7 at its lower end to move downward synchronously through the connecting column 5 until the telescopic block 3 contacts and is blocked by the limiting plate 8. At this time, the application disk 7 just reaches the predetermined height position. Then, start the motor 18 integrated in the connecting column 5. The output shaft of the motor 18 drives the rotating column 6 and the application disk 7 to rotate at high speed. The operator can then move the entire device smoothly by holding the ball 19, so that the rotating application disk 7 contacts the medicine on the surface of the backing material. The medicine is evenly spread by shearing and crushing action. After the application is completed, release the pressure on the holding ball 19. Under the elastic force of the spring 15 inside the reset cylinder 14, the reset column 16 pushes the reset plate 17 upward, which drives the connecting plate 4 and the application disk 7 to rise, so that the application disk 7 is removed from the surface of the backing material, making it convenient for the next operation or parameter adjustment.

[0032] Compared with the prior art, the beneficial effects of this utility model are as follows: the included application disc, telescopic block, motor, etc., enable the motor-driven high-speed rotating application disc to apply uniform shearing and crushing action to the ointment, ensuring that the drug coating on the surface of each patch is highly consistent in thickness and density, effectively guaranteeing the accuracy of product dosage and the uniformity of efficacy, significantly reducing the labor intensity of operators, and greatly improving production efficiency. Furthermore, the height of the limiting plate can be quickly adjusted according to different products, thereby precisely changing the thickness of the drug application. This structure is simple, novel in concept, convenient to use, and highly practical.

[0033] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model.

[0034] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
