[0002] Microporous S-knife patch is a topical patch product. The surface of this patch may be covered with tiny holes, which can increase the breathability of the patch, reduce the stuffiness and discomfort caused by long-term application of the skin, and also help the skin breathe normally. This patch is designed in the shape of an "S-knife" to better fit the physiological curve of specific parts of the human body and improve the stability and comfort of the patch. The drug ingredients in the microporous S-knife patch penetrate through the skin and play an anti-inflammatory, analgesic, and detumescent role. It can also be used to assist in the treatment of some chronic diseases, such as rheumatoid arthritis and cervical spondylosis. In the related art, the preparation method of the microporous S-knife patch is: first grind a variety of drugs and excipients into fine powder, then put the drug powder, pressure-sensitive adhesive and excipient powder into a mixing device in a certain proportion, stir and mix them thoroughly to form a uniform patch layer material, and then inject the patch layer material into a mold to form a microporous structure on the molded patch layer through a specific process method (such as laser drilling, mechanical drilling), and then use a cutting device to cut the patch layer with micropores according to the designed S-knife shape to make a microporous S-knife patch, and then put the cut microporous S-knife patch into a drying device for drying to remove moisture and solvents, and finally package it.

[0021] S2: Raw material weighing

[0022] A raw material for producing the microporous S-knife patch is placed on the carrier plate in the feeding box, and the weight of the raw material is measured in real time by a weight sensor. When the weight of the raw material reaches the required value, the raw material is stopped from being added to the carrier plate;

[0023] Then start the extension of the electric telescopic rod, and the output shaft of the electric telescopic rod will extend, driving the connecting vertical plate, the connecting horizontal plate, the weight sensor and the load-bearing plate to move horizontally to the left, and the weighed raw materials can fall into the preparation box.

10. A method for using the microporous S-knife patch production device according to any one of claims 1 to 9, characterized in that: The steps are as follows: S1: Preparation Check whether all parts of the device are firmly installed and whether the connection parts are well sealed, ensure that the motor (15), electric telescopic rod (6) and other equipment can operate normally, and the electromagnetic discharge valve (4) is in a closed state; Check whether the electric heating plate (27) and the temperature sensor (28) are working properly so as to control the temperature during the production process; Take the raw materials for the production of microporous S-knife patches, which include a variety of drugs, a variety of excipients and pressure-sensitive adhesives. S2: Raw material weighing A raw material for producing a microporous S-knife patch is placed on a carrier plate (10) in a feed box (5), and the weight of the raw material is measured in real time using a weight sensor (9). When the weight of the raw material reaches a required value, the addition of the raw material to the carrier plate (10) is stopped; Then, the electric telescopic rod (6) is started to extend and run, and the output shaft of the electric telescopic rod (6) is extended, driving the connecting vertical plate (7), the connecting horizontal plate (8), the weight sensor (9) and the carrying plate (10) to move horizontally to the left, and the weighed raw materials can fall into the preparation box (1). After the feeding is completed, the electric telescopic rod (6) is controlled to retract and reset, and the next raw material can be weighed and measured. According to the above operation steps, multiple raw materials can be accurately weighed in sequence and then put into the preparation box (1). S3: Raw material crushing When the first raw material in S2 is weighed and put into the preparation box (1), the motor (15) can be started to operate, and the motor (15) drives one of the crushing rollers (13) to rotate, and through the meshing action of the two gears (16), the two crushing rollers (13) rotate in opposite directions at the same time; After the raw materials enter the preparation box (1) from the feeding box (5), they fall onto two crushing rollers (13) and are crushed into larger granular powder by a plurality of crushing blades (14). S4: Raw material grinding The crushed raw materials fall onto the grinding seat (17). Since the top of the grinding seat (17) is in a peak-shaped structure, the raw materials are dispersed into each grinding chamber (18); When one of the crushing rollers (13) rotates, the second pulley (25) is driven to rotate through the first pulley (24) and the first belt (26), thereby driving one of the grinding rollers (20) to rotate. Since the three gears (23) are meshed in sequence, the three grinding rollers (20) rotate simultaneously, and the raw material is further ground into a finer powdery raw material by the multiple grinding grains (19) and the multiple grinding grains (21) on the grinding roller (20) in the grinding chamber (18). S5: Mixing of raw materials The ground powdered raw material continues to fall to the bottom of the preparation box (1); When one of the grinding rollers (20) rotates, the fourth belt pulley (32) is driven to rotate through the third belt pulley (31) and the second belt (33), thereby driving the stirring shaft (29) to rotate; A plurality of stirring rods (30) on the stirring shaft (29) stir and mix the powdered raw materials to make them uniformly mixed. During the stirring process, the electric heating plate (27) can heat the raw materials, and the temperature sensor (28) monitors the temperature in real time to ensure that the stirring and mixing is performed within a suitable temperature range. S6: Nesting When the raw materials are stirred and mixed uniformly, the electromagnetic discharge valve (4) is opened, and the mixed raw materials are discharged from the discharge pipe (3) for subsequent processing.
