[0010] As a further solution of the present invention, the flattening assembly includes a hollow roller, and a plurality of air ducts are opened outside the hollow roller. The same connecting frame is installed at both ends of the hollow roller, and the connecting frame passes through two sliding holes. Three springs are fixed at the bottom of the inner wall of the connecting frame, and the top of the spring is fixed to the inner wall of the bracket. One end of the hollow roller passes through the connecting frame and is equipped with a first rotary joint, and one end of the first rotary joint is connected to the top of the air duct.

[0011] As a further solution of the present invention, the driving assembly includes a second motor, which is installed on one side of the bottom of the ointment extruder. A driving gear is fixed on the output shaft of the second motor, and a driven gear is engaged with the outside of the driving gear. A discharge pipe is clamped in the middle of the driven gear, and a second rotary joint is installed at the top of the discharge pipe. A solenoid valve is installed on the second rotary joint, and the top of the solenoid valve is connected to the bottom of the ointment extruder, and the bottom end of the discharge pipe faces the interior of the coating assembly.

[0012] As a further solution of the present invention, the adjustment assembly includes a sliding sleeve, which is sleeved on the outside of the discharge pipe. A locking stud is provided on the sliding sleeve, and the sliding sleeve is connected to the discharge pipe through the locking stud. Cross bars are respectively installed on both sides of the sliding sleeve, and a slide is provided inside the cross bar. The top of the coating assembly is slidably connected in the two slides, and a through hole is provided on one of the cross bars.

[0013] As a further solution of the present invention, the coating assembly includes a scraper strip, one side of which is designed to be inclined, a baffle is fixed to the end of the scraper strip, and slides are fixed on both sides of the top of the scraper strip, one of the slides is equipped with a fixing screw, and the end of the fixing screw is connected to the adjustment assembly.

[0014] A method for using an ointment coating device for plaster production, the method comprising the following steps:

[0015] When applying the ointment, the dressing cloth on the unwinding roller passes through the fixed frame and is pulled onto the take-up roller, so that the dressing cloth is located between the guide assembly and the flattening assembly. The first motor is controlled to drive the transmission roller to rotate, and the transmission roller drives the PE conveyor belt to move. Because the transmission assemblies on the two transmission rollers are respectively connected to the ends of the unwinding roller and the take-up roller, the transmission roller, the unwinding roller and the take-up roller can rotate synchronously, and the take-up roller pulls the dressing cloth to move on the PE conveyor belt. Because the hollow roller is in contact with the dressing cloth and the elastic force of the spring supports the connecting frame, the connecting frame can drive the hollow roller to move downward and tightly adhere to the dressing cloth, and cooperate with the guide roller to support the dressing cloth, which can achieve the purpose of flattening the dressing cloth and play a role in wrinkle prevention.

[0016] The dressing cloth can drive the hollow roller to rotate during its movement, controlling the exhaust fan to work. The air duct extracts air from the inside of the hollow roller through the first rotary joint, and the external air can enter the hollow roller through the air duct. Because the hollow roller drives the multiple air ducts to rotate continuously, the air duct can absorb the dust attached to the outside of the dressing cloth, playing the role of cleaning the dressing cloth and ensuring the subsequent coating effect;

[0017] When the dressing cloth is located below the ointment extruder, the second motor is controlled to drive the driving gear to rotate, and the driving gear drives the discharge pipe to rotate in the second rotary joint through the driven gear, and the discharge pipe drives the two cross bars to rotate through the sliding sleeve, and the two cross bars drive the scraper to rotate through the sliding seat, and at the same time, the ointment extruder and the solenoid valve are started, so that the ointment passes through the solenoid valve and the second rotary joint and is discharged from the bottom end of the discharge pipe. Because the bottom end of the discharge pipe faces the inside of the scraper, the ointment is blocked by the scraper and the baffle to prevent the ointment from flowing out of the dressing cloth. Therefore, during the discharge of the discharge pipe, the discharge pipe and the scraper can rotate synchronously, and cooperate with the baffle on the scraper to evenly apply the ointment on the dressing cloth. The side of the scraper is designed with an inclined surface, and the scraper can gradually spread the ointment during the rotation process, thereby ensuring the uniformity of the ointment coating on the dressing cloth.

[0018] When adjusting the area and thickness of the ointment coating, the observation window in front of the fixed frame is opened, and the locking stud on the sliding sleeve is loosened so that the sliding sleeve can slide up and down outside the discharge pipe. The sliding sleeve drives the coating assembly below through the cross bar to adjust the distance between the dressing cloth and the scraper, and the locking stud is tightened to lock the sliding sleeve, thereby completing the adjustment of the coating thickness. When the ointment adjusts the coating area, the fixing screw on the slide is loosened so that the slide can move horizontally on the cross bar. When the slide drives the scraper to move to the left, the coating radius is reduced, so that the coating area of ​​the scraper is reduced. When the slide drives the scraper to move to the right, the coating radius is expanded, so that the coating area of ​​the scraper is increased.

[0019] After the coating of the dressing cloth is completed, the PE conveyor belt transports the dressing cloth to the right. By controlling the operation of the cooling fan, cold air blows towards the coated dressing cloth, which can cool the coated plaster and accelerate the solidification of the ointment. When the solidified ointment moves to the bottom of the cutting die, the two electric hydraulic rods are controlled to drive the cutting die to move downward. The cutting die can automatically cut the dressing cloth into plasters of different sizes for subsequent packaging processing. The remaining material after die-cutting is wound up by the winding roller.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When the dressing cloth is moved to the bottom of the ointment extruder, the second motor is activated to drive the driving gear to rotate, and the driving gear drives the discharge pipe to rotate in the second rotary joint through the driven gear. The discharge pipe drives the two cross bars to rotate through the sliding sleeve, and the two cross bars drive the scraper to rotate through the sliding seat. At the same time, the ointment extruder and the solenoid valve are started, so that the ointment passes through the solenoid valve and the second rotary joint and is discharged from the bottom end of the discharge pipe. Because the bottom end of the discharge pipe faces the inside of the scraper, the ointment is blocked by the scraper and the baffle to prevent The ointment flows out of the dressing cloth, so during the discharge process of the discharge pipe, the discharge pipe and the scraper can rotate synchronously, and cooperate with the baffle on the scraper to evenly apply the ointment on the dressing cloth. The side of the scraper is designed with a slope, and the scraper can gradually spread the ointment during the rotation process, abandoning the traditional direct spreading method, ensuring the uniformity of the ointment coating on the dressing cloth, and the coating thickness and area are uniform, so that the ointment is evenly distributed on the dressing cloth, improving the quality of the product and the subsequent treatment effect on the patient.

[0022] 2. The present invention adjusts the area and thickness of the ointment coating by loosening the locking stud on the sliding sleeve so that the sliding sleeve can slide up and down outside the discharge pipe, and the sliding sleeve drives the coating assembly below to be adjusted through the cross bar, so that the distance between the application cloth and the scraper strip is changed, and the locking stud is tightened to lock the sliding sleeve, thereby completing the adjustment of the coating thickness. When the ointment adjusts the coating area, the fixing screw on the slide is loosened so that the slide can move horizontally on the cross bar. When the slide drives the scraper strip to move left, the coating radius is reduced, so that the coating area of ​​the scraper strip is reduced. When the slide drives the scraper strip to move right, the coating radius is expanded, so that the coating area of ​​the scraper strip is increased. Therefore, the thickness and area of ​​the ointment coating can be freely adjusted to meet the preparation requirements of ointments of different specifications, making the coating device widely applicable.

[0023] 3. The present invention conveys the coated dressing cloth to the right through a PE conveyor belt. When the ointment is located under the cooling fan, the cooling fan works to blow cold air toward the coated dressing cloth, which can cool the coated plaster and accelerate the solidification of the ointment. When the solidified ointment moves to the bottom of the cutting die, the two electric hydraulic rods are controlled to drive the cutting die to move downward. The cutting die can automatically die-cut the dressing cloth into plasters of different sizes for subsequent packaging. After completing the die-cutting work of the dressing cloth, the winding roller can wind up the remaining material after die-cutting, which is convenient for independent collection of the remaining material and the plaster, thereby improving the convenience of operation.

[0024] 4. The present invention pulls the dressing cloth to move on the PE conveyor belt through the winding roller. Since the hollow roller is in contact with the dressing cloth and supports the connecting frame through the elastic force of the spring, the connecting frame can drive the hollow roller to move downward and tightly contact the dressing cloth, and cooperate with the guide roller to support the dressing cloth, which can achieve the purpose of flattening the dressing cloth and play a role in wrinkle prevention. During the movement, the dressing cloth can drive the hollow roller to rotate, and the exhaust fan works to make the air duct extract gas from the inside of the hollow roller through the first rotary joint. External gas can enter the inside of the hollow roller from the air duct. Because the hollow roller drives multiple air ducts to rotate continuously, the air duct can absorb dust attached to the outside of the dressing cloth, thereby cleaning the dressing cloth and improving the subsequent coating effect.

At the same time, the PE conveyor belt 4 has the properties of acid and alkali resistance, corrosion resistance and cutting resistance, and can prevent damage caused by cutting by the cutting die 16.

[0038] As a further embodiment of the present invention, Figure 2As shown, the transmission assembly 6 includes a driving wheel 601 and a driven wheel 602, one side of the driving wheel 601 is fixed to the end of the transmission roller 3, and the driving wheel 601 and the driven wheel 602 are outer-connected with a transmission belt 603, and the two driven wheels 602 are respectively fixed to the ends of the unwinding roller 7 and the winding roller 8; the first motor 5 is operated to drive the transmission roller 3 to rotate, and the end of the transmission roller 3 is connected to the driving wheel 601 in the transmission assembly 6, and the driving wheel 601 is connected to the driven wheel 602 through the transmission belt 603, so that the transmission roller 3 can drive the unwinding roller 7 and the winding roller 8 to rotate synchronously through the transmission assembly 6, thereby improving the stability of the movement of the dressing cloth.

[0039] like Figure 3 The support frame 2 is shown with a guide assembly 9 mounted therein, and a flattening assembly 10 mounted thereon. As a further embodiment of the present invention, the guide assembly 9 includes a bracket 901, the bottom of which is mounted on the support frame 2, and a guide roller 902 mounted on the top of the bracket 901. The guide roller 902 is positioned above the PE conveyor belt 4, and sliding holes 903 are formed on both sides of the bracket 901. The flattening assembly 10 slides through the two sliding holes 903.

[0040] like Figure 4 The flattening assembly 10 shown includes a hollow roller 101, which is located above the guide roller 902. The dressing fabric is located between the hollow roller 101 and the guide roller 902, and a number of air ducts 102 are opened on the outside. The same connecting frame 104 is installed at both ends of the hollow roller 101. The connecting frame 104 is U-shaped and passes through two sliding holes 903. Three springs 105 are fixed to the bottom of the inner wall of the connecting frame 104. The top of the spring 105 is fixed to the horizontal plate fixed at both ends of the inner wall of the bracket 901. The horizontal plate is located below the guide roller 902 and above the sliding hole 903.

[0041] The hollow roller 101 is in contact with the dressing cloth and supports the connecting frame 104 through the elastic force of the spring 105, so that the connecting frame 104 can drive the hollow roller 101 to move downward and tightly against the dressing cloth, and cooperate with the guide roller 902 to support the dressing cloth, so as to achieve the purpose of flattening the dressing cloth; in this embodiment, the sliding hole 903 is a long strip, and the interface of the connecting frame 104 is a matching rectangle, which can ensure that the guide roller 902 can support and flatten the dressing cloth, and cooperate with the connecting frame 104 to move in the sliding hole 903 to play a role in supporting and guiding the dressing cloth.

[0042] One end of the hollow roller 101 passes through the connecting frame 104 and is equipped with a first rotary joint 103. One end of the first rotary joint 103 is connected to the top of the air duct 11. The bottom end of the air duct 11 is connected to the exhaust fan 12. The exhaust fan 12 is installed on the bottom plate 1. The air duct 11 extracts gas from the inside of the hollow roller 101 through the first rotary joint 103. External gas can enter the inside of the hollow roller 101 from the air duct 102. Because the hollow roller 101 drives multiple air ducts 102 to rotate continuously, the air duct 102 can absorb dust attached to the outside of the dressing cloth, thereby cleaning the dressing cloth.

[0043] As a further embodiment of the present invention, Figure 5-6 As shown, a fixing frame 13 is provided on the support frame 2. The bottom of the fixing frame 13 is fixed to the base plate 1. An observation window 18 is installed on the front of the fixing frame 13. An ointment extruder 14 is installed in the fixing frame 13. A drive assembly 19 is installed at the bottom of the ointment extruder 14. An adjustment assembly 20 is installed at the bottom of the drive assembly 19. A coating assembly 21 is installed below the adjustment assembly 20. The coating assembly 21 is located above the PE conveyor belt 4. A cooling fan 15 is installed on one side of the fixing frame 13. A cutting die 16 is provided on one side of the cooling fan 15. The cooling fan 15 is located between the ointment extruder 14 and the cutting die 16. Two electric hydraulic rods 17 are fixed on the cutting die 16. The top end of the electric hydraulic rod 17 is fixed in the fixing frame 13.

[0044] During operation, the cooling fan 15 blows cold air toward the coated dressing cloth, which can cool the coated plaster and accelerate the solidification of the plaster. When the solidified plaster moves to the bottom of the cutting die 16, the two electric hydraulic rods 17 are controlled to drive the cutting die 16 to move downward. The cutting die 16 can automatically cut the dressing cloth into plasters of different sizes for subsequent packaging.

[0045] As a further embodiment of the present invention, Figure 7 As shown, the driving component 19 includes a second motor 191, which is installed on one side of the bottom of the ointment extruder 14. A driving gear 192 is fixed on the output shaft of the second motor 191, and a driven gear 193 is engaged with the outside of the driving gear 192. A discharge pipe 194 is clamped in the middle of the driven gear 193, and a second rotary joint 195 is installed at the top of the discharge pipe 194. A solenoid valve 196 is installed on the second rotary joint 195. The top of the solenoid valve 196 is connected to the bottom of the ointment extruder 14, and the bottom end of the discharge pipe 194 faces the interior of the coating component 21.

[0046] During operation, the ointment extruder 14 and the solenoid valve 196 are started, so that the ointment passes through the solenoid valve 196 and the second rotary joint 195 and is discharged from the bottom end of the discharge pipe 194, so that the discharge pipe 194 can rotate normally during the discharge process, which is convenient for dropping the ointment at multiple locations on the dressing cloth.

[0047] As a further solution of the present invention, the adjustment assembly 20 includes a sleeve 201, which is sleeved on the outside of the discharge pipe 194. The sleeve 201 is provided with a locking stud 202 that runs through the inside and outside. The sleeve 201 is connected to the discharge pipe 194 through the locking stud 202. Crossbars 203 are respectively installed on both sides of the sleeve 201. Slideways 204 are provided inside the crossbars 203. The top of the coating assembly 21 is slidably connected within the two slideways 204. A through hole 205 is provided on one of the crossbars 203. Because a fixed screw 214 passes through the through hole 205, the fixed screw 214 can move horizontally in the through hole 205. When adjusting the position of the coating assembly 21, the fixed screw 214 can be directly moved, thereby improving the convenience of operation. Loosen the locking screw 202 on the sleeve 201 to allow the sleeve 201 to slide up and down outside the discharge pipe 194. The sleeve 201 drives the coating component 21 below to adjust through the cross bar 203, so that the distance between the dressing cloth and the coating component 21 changes, making it easier to adjust the coating thickness.

[0048] like Figure 8 As shown, the coating component 21 includes a scraper 211, one side of the scraper 211 is designed to be inclined, and the inclined surface faces the right rear side of the dressing cloth, so that the scraper 211 can gradually spread the ointment during rotation, and a baffle 212 is fixed to the end of the scraper 211, and slides 213 are fixed on both sides of the top of the scraper 211, and a fixing screw 214 is installed on one of the slides 213. The end of the fixing screw 214 is connected to the adjustment component 20, and the bottom of the inner wall of the slide 204 in the adjustment component 20 is connected to the bottom end of the fixing screw 214, and then in the process of tightening the fixing screw 214, its bottom end can be tightly fitted with the bottom of the inner wall of the slide 204, so that the fixing screw 214 cannot slide freely in the through hole 205.

[0049] During operation, the fixing screw 214 on the slide 213 is loosened, so that the slide 213 can move horizontally on the cross bar 203. When the slide 213 drives the scraper 211 to move left, the coating radius is reduced, so that the coating area of ​​the scraper 211 is reduced. When the slide 213 drives the scraper 211 to move right, the coating radius is expanded, so that the coating area of ​​the scraper 211 is increased, which facilitates free adjustment of the coating area.

[0050] Because the scraper bar 211 can make a circular motion around the coating center, the coating area is only related to the distance between the end of the scraper bar 211 and the coating center. In the current state, the end of the scraper bar 211 and the baffle 212 are located at the rightmost side, so that the coating area can be maximized. At the same time, the other end of the scraper bar 211 is located to the left of the coating center, which does not affect the uniformity of the coating. The length of the scraper bar 211 is greater than the radius of the maximum coating area. Therefore, the coating area can be freely adjusted when the scraper bar 211 moves horizontally.

[0051] When the position of the slide 213 is adjusted, the fixing screw 214 is loosened to move it upward in the slide 213, so that the bottom end of the fixing screw 214 is separated from the bottom of the inner wall of the slide 204, and the locking state between the slide 213 and the right cross bar 203 can be released. The fixing screw 214 is directly moved to slide in the through hole 205, and the fixing screw 214 drives the scraper 211 to move horizontally through the slide 213. After tightening the fixing screw 214, the fixing screw 214 moves downward and fits tightly with the bottom of the inner wall of the slide 204, which can lock the slide 213 and the right cross bar 203, thereby preventing the scraper 211 under the slide 213 from sliding freely.

[0052] A method for using an ointment coating device for plaster production, the method comprising the following steps:

[0053] When applying the ointment, the dressing cloth on the unwinding roller 7 passes through the fixed frame 13 and is pulled onto the winding roller 8, so that the dressing cloth is located between the hollow roller 101 and the guide roller 902. The first motor 5 is controlled to drive the transmission roller 3 to rotate, and the transmission roller 3 drives the PE conveyor belt 4 to move. Because the transmission components 6 on the two transmission rollers 3 are respectively connected to the ends of the unwinding roller 7 and the winding roller 8, the transmission roller 3, the unwinding roller 7 and the winding roller 8 can rotate synchronously, and the winding roller 8 pulls the dressing cloth to move on the PE conveyor belt 4. Because the hollow roller 101 is in contact with the dressing cloth and the elastic force of the spring 105 supports the connecting frame 104, the connecting frame 104 can drive the hollow roller 101 to move downward and close to the dressing cloth, and cooperate with the guide roller 902 to support the dressing cloth, it can achieve the purpose of flattening the dressing cloth and play an anti-wrinkle role.

[0054] During the movement of the dressing cloth, the hollow roller 101 can be driven to rotate, and the exhaust fan 12 can be controlled to work. The air duct 11 extracts gas from the inside of the hollow roller 101 through the first rotary joint 103, and the external gas can enter the inside of the hollow roller 101 from the air duct 102. Because the hollow roller 101 drives the multiple air ducts 102 to rotate continuously, the air duct 102 can absorb the dust attached to the outside of the dressing cloth, play a role in cleaning the dressing cloth, and ensure the subsequent coating effect.

[0055] When the dressing cloth is located below the ointment extruder 14, the second motor 191 is controlled to work so that it drives the driving gear 192 to rotate, and the driving gear 192 drives the discharge pipe 194 to rotate in the second rotary joint 195 through the driven gear 193. The discharge pipe 194 drives the two cross bars 203 to rotate through the sliding sleeve 201, and the two cross bars 203 drive the scraper 211 to rotate through the slide 213. At the same time, the ointment extruder 14 and the solenoid valve 196 are started, so that the ointment passes through the solenoid valve 196, the second rotary joint 195 and out of the ointment. The ointment is discharged from the bottom end of the discharge tube 194. Since the bottom end of the discharge tube 194 faces the inside of the scraper bar 211, the ointment is blocked by the scraper bar 211 and the baffle 212 to prevent the ointment from flowing out of the dressing cloth. Therefore, during the discharge process of the discharge tube 194, the discharge tube 194 and the scraper bar 211 can rotate synchronously, and cooperate with the baffle 212 on the scraper bar 211 to evenly apply the ointment to the dressing cloth. The side surface of the scraper bar 211 is designed with an inclined surface. The scraper bar 211 can gradually spread the ointment during the rotation process, ensuring the uniformity of the ointment coating on the dressing cloth.

[0056] When adjusting the area and thickness of the ointment coating, by opening the observation window 18 in front of the fixing frame 13, loosening the locking stud 202 on the sliding sleeve 201 allows the sliding sleeve 201 to slide up and down outside the discharge pipe 194, and the sliding sleeve 201 drives the coating assembly 21 below to adjust through the cross bar 203, so that the distance between the dressing cloth and the scraper 211 is changed, and the locking stud 202 is tightened to lock the sliding sleeve 201, thereby completing the adjustment of the coating thickness. When the ointment adjusts the coating area, loosen the fixing screw 214 on the slide 213 so that the slide 213 can move horizontally on the cross bar 203. When the slide 213 drives the scraper 211 to move left, the coating radius is reduced, so that the coating area of ​​the scraper 211 is reduced. When the slide 213 drives the scraper 211 to move right, the coating radius is expanded, so that the coating area of ​​the scraper 211 is increased.

[0057] After completing the coating of the dressing cloth, the PE conveyor belt 4 conveys the dressing cloth to the right. By controlling the operation of the cold fan 15, cold air blows toward the coated dressing cloth, which can cool the coated plaster and accelerate the solidification of the plaster. When the solidified plaster moves to the bottom of the cutting die 16, the two electric hydraulic rods 17 are controlled to drive the cutting die 16 to move downward. The cutting die 16 can automatically die-cut the dressing cloth into plasters of different sizes for subsequent packaging processing. The remaining material after die-cutting is wound up by the winding roller 8.

9. A method for using a plaster coating device for plaster production, according to any one of claims 1 to 8, characterized in that: The method of use comprises the following steps: When applying the ointment, the dressing cloth on the unwinding roller (7) passes through the fixed frame (13) and is pulled onto the winding roller (8), so that the dressing cloth is located between the guide component (9) and the flattening component (10). The first motor (5) is controlled to drive the transmission roller (3) to rotate, and the transmission roller (3) drives the PE conveyor belt (4) to move. Since the transmission components (6) on the two transmission rollers (3) are respectively connected to the ends of the unwinding roller (7) and the winding roller (8), the transmission roller (3) The unwinding roller (7) and the winding roller (8) can rotate synchronously, and the winding roller (8) pulls the dressing cloth to move on the PE conveyor belt (4). Since the hollow roller (101) is in contact with the dressing cloth and supports the connecting frame (104) through the elastic force of the spring (105), the connecting frame (104) can drive the hollow roller (101) to move downward and closely contact the dressing cloth, and cooperate with the guide roller (902) to support the dressing cloth, so as to achieve the purpose of flattening the dressing cloth and play an anti-wrinkle role; During the movement of the dressing cloth, the hollow roller (101) can be driven to rotate, and the exhaust fan (12) can be controlled to work. The air duct (11) extracts gas from the inside of the hollow roller (101) through the first rotating joint (103), and external gas can enter the inside of the hollow roller (101) through the air duct (102). Since the hollow roller (101) drives the multiple air ducts (102) to rotate continuously, the air duct (102) can absorb dust attached to the outside of the dressing cloth, thereby playing a role in cleaning the dressing cloth and ensuring the subsequent coating effect; When the dressing cloth is located below the ointment extruder (14), the second motor (191) is controlled to work so as to drive the driving gear (192) to rotate. The driving gear (192) drives the discharge pipe (194) to rotate in the second rotary joint (195) through the driven gear (193). The discharge pipe (194) drives the two cross bars (203) to rotate through the sliding sleeve (201). The two cross bars (203) drive the scraper (211) to rotate through the sliding seat (213). At the same time, the ointment extruder (14) and the electromagnetic valve (196) are started, so that the ointment passes through the electromagnetic valve (196) and the second rotary joint (195). The ointment is discharged from the bottom end of the discharge pipe (194). Since the bottom end of the discharge pipe (194) faces the inside of the scraper (211), the ointment is blocked by the scraper (211) and the baffle (212) to prevent the ointment from flowing out of the dressing cloth. Therefore, during the discharge process of the discharge pipe (194), the discharge pipe (194) and the scraper (211) can rotate synchronously, and cooperate with the baffle (212) on the scraper (211) to evenly coat the ointment on the dressing cloth. The side surface of the scraper (211) is designed as an inclined surface. The scraper (211) can gradually spread the ointment during the rotation process, thereby ensuring the uniformity of the ointment coating on the dressing cloth. When adjusting the area and thickness of the ointment coating, the observation window (18) in front of the fixing frame (13) is opened, and the locking stud (202) on the sliding sleeve (201) is loosened to allow the sliding sleeve (201) to slide up and down outside the discharge pipe (194). The sliding sleeve (201) drives the coating assembly (21) below to adjust through the cross bar (203), so that the distance between the application cloth and the scraper (211) changes. The locking stud (202) is tightened to lock the sliding sleeve (201). The coating thickness is adjusted, and the ointment is adjusted to the coating area by loosening the fixing screw (214) on the slide seat (213) so that the slide seat (213) can move horizontally on the cross bar (203). When the slide seat (213) drives the scraper (211) to move leftward, the coating radius is reduced, so that the coating area of ​​the scraper (211) is reduced. When the slide seat (213) drives the scraper (211) to move rightward, the coating radius is expanded, so that the coating area of ​​the scraper (211) is increased. After the coating of the dressing cloth is completed, the PE conveyor belt (4) conveys the dressing cloth to the right. By controlling the operation of the cold fan (15), cold air is blown toward the coated dressing cloth, which can cool the coated plaster and accelerate the solidification of the plaster. When the solidified plaster moves to the bottom of the cutting die (16), the two electric hydraulic rods (17) are controlled to drive the cutting die (16) to move downward. The cutting die (16) can automatically die-cut the dressing cloth into plasters of different sizes for subsequent packaging. The remaining material after die-cutting is rolled up by the winding roller (8).
