Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to a tablet ejecting device for epinastine hydrochloride tablets. Background Art

[0002] Tablet presses, also known as punching machines, are suitable for pressing powdered and granular materials into tablets, including Western and Traditional Chinese Medicine tablets, disinfectant tablets, oral tablets, sugar tablets, special-shaped tablets, and milk tablets. They are suitable for production and experimental use in industries such as pharmaceuticals, chemical engineering, universities and colleges, pharmacies, hospitals, and healthcare products. Tablet presses compress powdered materials into tablets or pills. Tablet presses generally have a discharge channel at the exit, through which the pressed tablets pass into a collection container for the next packaging process. After tablets are pressed and formed by the tablet press, a large amount of dust will remain on the surface, and powder will also remain in the tablet's pressing groove.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese patent announcement number: CN219706184U discloses a tablet pressing device, which includes a base, a box body above the base, a template on the top of the box body, a plurality of material holes passing through the template, two annular blocks are arranged in the material holes, a connecting column is arranged in the annular block, and sealing plates are fixed to the upper and lower connecting columns, connecting rods are fixed at both ends of the template, a fan-shaped plate is arranged on the outside of the connecting rod, a motor is fixedly arranged on one side of the box body, and a connecting rod is fixedly connected to the output end of the motor, a strip groove is provided on the inner wall of the box body, a filter plate is provided under the template, and protrusions are provided on the side of the filter plate, and a spring is fixed between the bottom surface of the strip groove and the protrusion. The utility model realizes tableting on one side of the template by arranging annular blocks, sealing plates and connecting columns in the material holes, and ejects the prepared tablets and residual powder on the other side. At the same time, the spiral plate is shaken by the cooperation of the fan-shaped plate, the protrusion and the spring to separate the tablets from the powder.

[0005] However, the above patent still has some problems in actual use. The most obvious one is that after repeated use, the sealing plate will cause wear due to friction between it and the inner wall of the material hole, thereby causing a gap between the sealing plate and the material hole, affecting the cleaning effect and efficiency of the residual drug powder on the inner wall of the material hole.

[0006] To this end, we proposed an epinastine hydrochloride tablet ejection device to solve the above-mentioned drawbacks. Utility Model Content

[0041] Working principle: When in use, the corresponding medicine powder (which can be epinastine hydrochloride powder) is injected into the material hole 8, and the electric telescopic rod is started to drive the upper mold to move downward, so that the medicine powder pushed into the material hole 8 can be tableted. After the tableting is completed, the second drive motor 3 drives the template 7 to flip 180 degrees and makes the material hole 8 face downward. Then the first drive motor 23 drives the first gear 24 to rotate.

It should be noted that the upward movement of the bracket 21 is greater than the depth of the material hole 8, and when ejecting the epinastine hydrochloride tablets, the number of revolutions of the first drive motor 23 can be controlled by the control panel 6, thereby controlling the upward movement of the bracket 21 and making the surface of the ejection plate 27 flush with the surface of the template 7 to avoid the scraper plate 211 being thrown out when no maintenance is required.

[0042] It should be noted that the models and specifications of the first drive motor 23, the second drive motor 3 and the third drive motor 25 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0043] The power supply and principles of the first drive motor 23 , the second drive motor 3 and the third drive motor 25 are clear to those skilled in the art and will not be described in detail here.
