A hydrogel medical dressing coating machine

Abstract

The present invention provides a hydrogel medical patch coating machine. The hydrogel medical patch coating machine includes: a device base, a coating frame provided on the device base, a spiral feed barrel installed on the coating frame, and a coating head installed at the lower end of the spiral feed barrel; by adjusting the rotation of the adjustment screw, a limit plate is pushed to move, and the limit plate drives the top pressure sleeve to move along the axis of the support column. When the top pressure sleeve moves, the connecting rod connected to it pushes the adjustment ring to deflect, and at the same time, the driving motor drives the support column to rotate, and the support column drives the deflected adjustment ring to rotate. During the rotation process, the limit ring groove on the outer ring pushes the sliding column to reciprocate along the axis of the support column, thereby driving the distribution plate to reciprocate. When the rubber material output by the spiral feed barrel passes through the distribution plate, the material leveling rod on the distribution plate can disperse the concentrated rubber material, prevent the rubber material from falling, and ensure that the rubber material can be evenly distributed, thereby improving the uniformity of the rubber material coating.

Description

Technical Field

[0001] The invention relates to the field of medical patch production equipment, and in particular to a hydrogel medical patch coating machine. Background Art

[0002] Medical compresses are modified plasters based on traditional cold compresses (such as cold water, ice water, and alcohol). The vaporization of water and natural cooling ingredients in the polymer gel removes heat, achieving local cooling. The drug components, combined with the hydrogel, undergo hydration, allowing them to rapidly penetrate the fat layer and subcutaneous tissue, reaching the affected area directly. This provides a cold compress for pain relief, transdermal absorption, and sustained-release drug delivery. Medical compresses can constrict local capillaries, reduce local congestion, decrease nerve ending sensitivity, and alleviate pain. They can also reduce fever and reduce local blood flow, preventing the spread of inflammation and suppuration. They dissipate heat within the body, increasing heat dissipation and lowering body temperature. Cold compresses are suitable for individuals requiring cold compresses, such as those with early-stage local soft tissue injuries, those with high fever, those suffering from heatstroke, and those with toothaches.

[0003] In the coating process of existing medical patch coating equipment, the adhesive is input from the material pipe to the backing layer for coating. Since the adhesive clumps and sticks to the backing layer, it is easy to cause uneven coating and poor coating effect. Summary of the Invention

A material leveling rod 23 is provided on the side of the cloth plate 22. A support column 24 is provided on the coating frame 12, and one end of the support column 24 is connected to the output end of the driving motor. A top pressure sleeve 25 is slidably installed on the support column 24, and a limiting groove 26 is provided on the inner ring side of the top pressure sleeve 25. A guide ridge 27 is provided on the outer side of the support column 24 along the axial direction. The guide ridge 27 is located inside the limiting groove 26. An adjusting screw 28 is installed on the coating frame 12 through a threaded connection, and a limiting disk 29 is fixed at one end of the adjusting screw 28. The outer ring of the top pressure sleeve 25 is provided with a toggle groove 30. The limiting The disk 29 slides in the toggle slot 30, and a knob 31 is fixedly installed at the other end of the adjusting screw 28. An intermediate rod 32 is rotated and passed through the support column 24, and the intermediate rod 32 is perpendicular to the axis of the support column 24. An adjusting ring 33 is installed on the support column 24, and the adjusting ring 33 is fixed on the intermediate rod 32. A connecting rod 34 is hinged on the top pressure sleeve 25, and the other end of the connecting rod 34 is hinged on the adjusting ring 33. The connecting rod 34 and the intermediate rod 32 are not on the same plane. A limiting ring groove 35 is provided on the outer ring of the adjusting ring 33, and a sliding column 36 is provided on the side of the cloth plate 22. A buffer wheel 37 is installed on the end of the sliding column 36, and the buffer wheel 37 is located inside the limiting ring groove 35.

[0025] A hydrogel medical dressing coating machine, working principle:

[0026] By rotating the adjusting screw 28, the limiting plate 29 is moved, which drives the pressure sleeve 25 along the axis of the support column 24. As the pressure sleeve 25 moves, the connecting rod 34 connected to it pushes the adjustment ring 33 to deflect around the intermediate rod 32. Simultaneously, the drive motor drives the support column 24 to rotate, which in turn drives the deflected adjustment ring 33. During this rotation, the limiting ring groove 35 on its outer ring pushes the sliding post 36 to reciprocate along the axis of the support column 24, thereby driving the distribution plate 22 to reciprocate. As the rubber material discharged by the spiral feed cylinder 13 passes through the distribution plate 22, the material leveling rod 23 on the distribution plate 22 disperses the concentrated rubber material, preventing it from falling and ensuring uniform distribution, thereby improving the uniformity of the rubber coating. The reciprocating amplitude of the distribution plate 22 can be adjusted according to the deflection amplitude of the adjusting ring 33. The adjustment process does not require shutting down the drive motor, enabling dynamic adjustment of the reciprocating amplitude of the distribution plate 22.

[0027] Example 2

[0028] On the basis of Example 1, Figure 1 、 Figure 4As shown; a silo 41 is provided on the upper portion of the coating frame 12, a spiral feeding barrel 13 is provided at the lower portion of the silo 41, a feeding screw 42 is installed inside the spiral feeding barrel 13, the upper end of the feeding screw 42 is coaxially connected to a rotating rod 43, the upper end of the rotating rod 43 extends out of the silo 41 and is connected to a feeding motor 44, and a stirring rod 45 is installed on the rotating rod 43.

[0029] The rubber material is added to the silo 41. Before coating, the feeding motor 44 is used to drive the rotating rod 43 to rotate, and the rotating rod 43 drives the stirring rod 45 to rotate, thereby stirring the rubber material inside the silo 41 to prevent the rubber material from agglomerating and improve the mixing effect of the rubber material.

[0033] The lifting screw 60 is parallel to the scraper 56 and perpendicular to the support column 24 .

[0034] During the coating process, it is necessary to adjust the coating thickness of the rubber material. The transmission rod 62 is driven to rotate by rotating the hand wheel 63. The transmission rod 62 drives the driving gear 61 to rotate. The driving gear 61 pushes the side support block 58 to rise and fall along the axis of the lifting screw 60, thereby driving the lifting cylinder 53 to rise and fall. When the lifting cylinder 53 moves, it drives the scraper 56 to move, thereby adjusting the distance between the scraper 56 and the backing layer, and then adjusting the coating thickness of the rubber material.
