Description

Technical Field

[0001] The invention relates to the technical field of tablet pressing machines for producing medical liquid wound dressings, in particular to a tablet pressing machine for producing medical liquid wound dressings. Background Art

[0002] Hydrogel is a type of three-dimensional network polymer with high water content, usually made of natural or synthetic polymer materials. It can absorb a large amount of water or biological fluids and maintain good physical strength. Due to its excellent moisture retention, breathability and good biocompatibility, hydrogel has been widely used in the medical field, especially in wound care. Hydrogel dressings have become one of the ideal materials for treating chronic wounds, burns, postoperative wounds, etc. due to their softness, easy molding and ability to provide a moist healing environment for wounds.

[0003] The existing Chinese patent with announcement number CN213648798U includes a base, one side of the base is threadedly connected to a lifting screw through a threaded block, one end of the lifting screw is threadedly connected to a bracket, one side of the bracket is fixedly installed with a motor, the output end of the motor is fixedly installed with a rotating rod, one end of the rotating rod is rotatably connected to a connecting rod, one end of the connecting rod is rotatably connected to a support rod, the middle part of the support rod is rotatably connected to one side of the bracket through a vertical rod, one end of the support rod is rotatably connected to a push rod, and the push rod is slidably connected to one side of the bracket.

[0004] When the above device is in use, the setting of the bracket and the motor makes the tablet pressing device have the effects of simple structure, easy use and maintenance. Through the coordinated setting of the transmission rod and the push rod, the rotating rod can be driven to rotate by the motor during use.

[0055] When in use, the fixing block 24 is provided on the first partition plate 3, and the T-shaped rod 25 is provided on the fixing block 24, so that the fixing block 24 fixes and supports the T-shaped rod 25 on the first partition plate 3, and the T-shaped rod 25 is horizontally movable and connected on the fixing block 24, and the connecting seat 26 is provided on the T-shaped rod 25, and the second movable groove 222 provided on the adjusting rod 22 is sleeved on the inner wall of the second movable groove 222 for support, and the rotating rod 27 is provided on the second partition plate 9, so that the rotating rod 27 is on the second partition plate 9. The third movable groove 271 provided on the rotating rod 27 is used for rotational connection. The third movable groove 271 can support the T-shaped rod 25. The roller 28 provided on the rotating rod 27 and the third spring 30 provided on the connecting seat 26 can drive the roller 28 to fit the outer contour of the circular plate 13 under the elastic force of the third spring 30, and the circular plate 13 is rotated along with the fixed axis, so that the roller 28 can be fixed on the rotating rod 27 along with the circular plate 13, thereby reducing the friction between the roller 28 and the circular plate 13.

[0056] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, by the arc block 29 set on the circular plate 13, when the lower pressing plate 6 is lifted to the top of the pressing groove 301 and is at the same horizontal plane with the first partition plate 3, the roller 28 moves and contacts the arc block 29, so that the rotating rod 27 drives the T-shaped rod 25 and the connecting seat 26 at the bottom to move in the direction close to the adjusting rod 22 under the push of the arc block 29, and the adjusting rod 22 pulls the fixed tube 23 and the trapezoidal block 21 to move horizontally in the direction close to the pressing groove 301 under the push of the connecting seat 26, so that the trapezoidal block 21 fits with the surface of the first partition plate 3, so that the trapezoidal block 21 can move The hydrogel dressing formed on the surface of the lower pressing plate 6 is demoulded, and the demoulded hydrogel dressing is laid on the inclined surface of the trapezoidal block 21.

When the trapezoidal block 21 moves to demould the hydrogel dressing on the surface of the lower pressing plate 6, the trapezoidal block 21 drives the fixed tube 23 to be in the corresponding position of the pressing groove 301, so that the hydrogel inside the storage hopper 31 can be filled into the inner wall of the pressing groove 301 through the fixed tube 23 under the action of gravity. Since the viscosity of the hydrogel is relatively high and the flow rate is slow, the trapezoidal block 21 shakes back and forth, which further improves the feeding effect of the storage hopper 31 on the inside of the pressing groove 301.

[0060] Furthermore, the existing device can automatically take out the hydrogel dressing formed by compression molding from the compression mold during actual use, which is convenient to use and better than traditional products.
