[0039] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 In one aspect of the present embodiment, the flip extrusion assembly includes a slide bar 5, an L-shaped block 1 6, a threaded rod 7, an L-shaped block 2 8, a flip rod 9, a flip gear 25 and a rack 26. The slide bar 5 is installed on one side of the inner wall of the coating tank 1, the L-shaped block 1 6 slides on the outside of the slide bar 5, the threaded rod 7 is rotatably connected to the side of the inner wall of the coating tank 1 away from the slide bar 5, the bottom of the threaded rod 7 extends to the inside of the transmission groove 4, the L-shaped block 2 8 is threadedly connected on the outside of the threaded rod 7, the flip rod 9 rotates between the L-shaped block 1 6 and the L-shaped block 2 8, the flip gear 25 is fixed on the outside of one end of the flip rod 9, the rack 26 is installed at the bottom of the inner wall of the coating tank 1, and the flip gear 25 is meshed with the rack 26.

[0040] When the threaded rod 7 rotates, it drives the L-shaped block 1 6 and the L-shaped block 2 8 to move up and down inside the applicator jar 1, thereby driving the flip rod 9 to move up and down. At the same time, by utilizing the engagement between the flip gear 25 and the rack 26, the flip rod 9 can flip while moving up and down, thereby driving the tail of the ointment packaging bag to flip and wrap.

[0041] A through slot 20 is provided inside the flip rod 9, an L-shaped plate 21 is slidably installed inside the through slot 20, and two second springs 22 are installed between the outer side of the L-shaped plate 21 and the inner wall of the through slot 20.

[0042] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In one aspect of the present embodiment, the transmission adjustment assembly includes a square groove 10, a T-block 11, a first spring 12, a sleeve 13, a sleeve 2 14, a first bevel gear 15 and a second bevel gear 16. The square groove 10 is arranged inside the rotating shaft at one end of the coating roller 3. One end of the rotating shaft of the coating roller 3 with the square groove 10 extends to the inside of the transmission groove 4. The T-block 11 slides inside the square groove 10. The first spring 12 is installed between the T-block 11 and the inner wall of the square groove 10. The sleeve 13 is fixed on the end of the T-block 11 away from the square groove 10.

The ends of the sleeve 13 and the sleeve 2 14 that are close to each other are both provided with mutually matching corrugated structures. The first bevel gear 15 is fixed on the outside of the sleeve 2 14. The second bevel gear 16 is fixed at the bottom of the threaded rod 7. The first bevel gear 15 is meshed with the second bevel gear 16.

[0043] When the operator pushes the applicator roller 3 to rotate in one direction on the patient's skin, the rotating shaft at one end thereof drives the T-block 11, sleeve 13 and sleeve 2 14 to rotate, thereby driving the first bevel gear 15 to rotate, and the second bevel gear 16 drives the threaded rod 7 to rotate, thereby driving the flip extrusion assembly to operate, squeezing the ointment packaging bag, so that the ointment falls on the outside of the applicator roller 3 through the semicircular groove, and the applicator roller 3 is used to better perform the application operation.

[0044] Working principle:

[0045] When in use, first open the sealing cover 24 on the outside of the applicator jar 1, place the head of the ointment packaging bag inside the semicircular slot through the notch 23, and then use the rotation of the adjusting screw 18 to drive the pressing block 19 to move inside the slide slot 17, so that the pressing block 19 and the semicircular slot are used to clamp and fix the head of the ointment packaging bag;

[0046] Then, the tail of the ointment packaging bag is placed between the through slot 20 and the L-shaped plate 21, and the L-shaped plate 21 clamps the tail of the ointment packaging bag by the elastic force of the second spring 22, so that the tail of the ointment packaging bag can be turned over and wound with the turning rod 9.

[0047] Then, when the operator pushes the applicator roller 3 to rotate in one direction on the patient's skin, the rotating shaft at one end thereof drives the T-block 11, the sleeve 13 and the sleeve 2 14 to rotate, thereby driving the first bevel gear 15 to rotate, and the second bevel gear 16 drives the threaded rod 7 to rotate, thereby driving the flipping and extruding assembly to operate, squeeze the ointment packaging bag, so that the ointment falls on the outside of the applicator roller 3 through the semicircular card groove, and the applicator roller 3 can be used to quickly apply the squeezed ointment on the patient's skin over a large area, without manually squeezing the ointment, which is conducive to practical application and operation;

[0048] When the L-shaped block 1 6 and the L-shaped block 2 8 move to the bottom of the inner wall of the medicine coating tank 1 and continue to push the medicine coating roller 3 to rotate on the patient's skin, the second bevel gear 16 no longer rotates due to the resistance, so the first bevel gear 15 and the sleeve 2 14 no longer rotate. At this time, under the action of the wavy structure at one end of the sleeve 13 and the sleeve 2 14, and in cooperation with the elastic force of the first spring 12, the sleeve 13 is made to jump left and right at one end of the sleeve 2 14, so it will not hinder the rotation of the medicine coating roller 3, but the operator will feel the resistance caused by the wavy structure, and when it pushes the medicine coating roller 3 in the reverse direction to rotate, it can drive the flip extrusion assembly to operate in the reverse direction, so that the ointment packaging bag is no longer squeezed, and then the medicine coating roller 3 is pushed in the reverse direction to rotate again, so that the ointment packaging bag can be repeatedly squeezed, thereby preventing residue and avoiding drug waste.

[0049] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
