[0002] Dental plaster, with its plasticity, stability and biocompatibility, has become an indispensable material in dental treatment. It is used to replicate the precise shape of a patient's teeth and help doctors develop orthodontic plans and design dentures or restorations.

[0003] A search revealed Chinese patent publication number CN221536353U, which discloses a dental plaster mixing device. This patent involves placing raw materials inside a container, starting a motor to drive a limiting rod, a connecting sleeve, and a rotating shaft to rotate. The rotating shaft drives a stirring plate to rotate via an installation rod, causing the stirring plate to stir the plaster. However, this device has certain problems: the stirring plate only stirs the plaster horizontally and cannot comprehensively scrape and compact the plaster. If there are lumps in the plaster, it will affect the quality of the plaster model. Utility Model Content

[0004] The purpose of this invention is to provide a dental plaster preparation and mixing device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0007] The scraping mechanism includes multiple pusher plates, which are evenly distributed around the circumference of the rotating shaft. The pusher plates abut against the inner wall of the cylinder. A mounting plate is fixedly connected to the side of the pusher plate near the rotating shaft. A fixing rod is hinged to the end of the mounting plate near the rotating shaft. The fixing rod is fixedly installed on the rotating shaft. Multiple protrusions are fixedly installed on the inner wall of the cylinder, which are evenly distributed around the circumference of the cylinder. The protrusions are V-shaped with their tips close to the rotating shaft.

[0008] Preferably, a tilting plate is fixedly installed on the rotating shaft. The tilting plate is spiral-shaped, and a power motor is fixedly installed at the upper end of the cylinder. The output shaft of the power motor is fixedly connected to the rotating shaft.

[0009] Preferably, the rotating shaft is provided with a scraping component, which includes multiple connecting rods. The connecting rods are fixedly connected to the lower end of the rotating shaft, and the multiple connecting rods are evenly distributed along the circumference of the rotating shaft.

[0010] Preferably, a scraper is fixedly connected to the end of the connecting rod away from the rotating shaft. The scraper is arc-shaped, and the lower end of the scraper abuts against the bottom wall of the cylinder.

[0011] Preferably, a feed pipe is fixedly connected to one side of the upper end of the cylinder, the feed pipe is connected to the inside of the cylinder, and a cover is hinged to the upper end of the feed pipe.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a dental plaster preparation and mixing device includes a base plate 101, symmetrical support frames 103 fixed on both sides of the base plate 101, a cylinder 102 fixedly installed between the symmetrical support frames 103, a rotating shaft 302 coaxially rotatably connected inside the cylinder 102, and a scraping mechanism provided on the rotating shaft 302.

[0027] The scraping mechanism includes multiple pusher plates 403, which are evenly distributed around the circumference of the rotating shaft 302. The pusher plates 403 abut against the inner wall of the cylinder 102. A mounting plate 402 is fixedly connected to the side of the pusher plate 403 near the rotating shaft 302. A fixing rod 401 is hinged to the end of the mounting plate 402 near the rotating shaft 302. A torsion spring is installed in the hinge shaft of the mounting plate 402. The fixing rod 401 is fixedly installed on the rotating shaft 302. Multiple protrusions 404 are fixedly installed on the inner wall of the cylinder 102, which are evenly distributed around the circumference of the cylinder 102. The protrusions 404 are pointed close to each other. The V-shape of the rotating shaft 302 drives the fixed rod 401 to rotate. The fixed rod 401 drives the pusher plate 403 to rotate around the rotating shaft 302, pushing the plaster. This causes the plaster to move towards the inner wall of the cylinder 102 and scrape the inner wall of the cylinder 102 through the pusher plate 403. As the rotating shaft 302 rotates, it drives the pusher plate 403 to squeeze the protrusion 404, thereby squeezing the plaster between the pusher plate 403 and the protrusion 404, crushing the lumps in the plaster, making the prepared plaster more delicate. After the pusher plate 403 separates from the protrusion 404, it restores its deformation and generates vibration, which helps to eliminate air bubbles in the plaster.

[0028] A flipping plate 303 is fixedly installed on the rotating shaft 302. The flipping plate 303 is spiral in shape. A power motor 301 is fixedly installed on the upper end of the cylinder 102. The output shaft of the power motor 301 is fixedly connected to the rotating shaft 302. The power motor 301 drives the rotating shaft 302 to rotate, so that the rotating shaft 302 drives the flipping plate 303 to rotate, and stirs the gypsum in the cylinder 102 evenly.

[0029] The rotating shaft 302 is provided with a scraping assembly, which includes multiple connecting rods 501. The connecting rods 501 are fixedly connected to the lower end of the rotating shaft 302, and the multiple connecting rods 501 are evenly distributed around the circumference of the rotating shaft 302.

[0030] A scraper 502 is fixedly connected to one end of the connecting rod 501 away from the rotating shaft 302. The scraper 502 is arc-shaped, and the lower end of the scraper 502 abuts against the bottom wall of the cylinder 102. The connecting rod 501 drives the scraper 502 to rotate with the rotating shaft 302, so that the scraper 502 scrapes the bottom wall of the cylinder 102 and causes the plaster to move along the arc of the scraper 502 towards the rotating shaft 302.

[0031] A feed pipe 201 is fixedly connected to one side of the upper end of the cylinder 102. The feed pipe 201 is connected to the inside of the cylinder 102. A cover 202 is hinged to the upper end of the feed pipe 201. When in use, the cover 202 is flipped over and the gypsum powder is poured into the cylinder 102 through the feed pipe 201.

[0032] A discharge pipe 601 is fixedly connected to the lower end of the cylinder 102. A discharge valve 602 is fixedly installed on the discharge pipe 601. When discharging, the discharge valve 602 is opened so that the gypsum can be discharged through the discharge pipe 601.

[0033] A water inlet pipe 7 is fixedly connected to the upper end of the cylinder 102. The water inlet pipe 7 is located on the side of the cylinder 102 away from the feed pipe 201.

[0034] Working principle: During use, the cover 202 is flipped over, and gypsum powder is poured into the cylinder 102 through the feed pipe 201. Water is added to the cylinder 102 through the water inlet pipe 7. Then, the motor 301 drives the rotating shaft 302 to rotate, causing the rotating shaft 302 to drive the flipping plate 303 to rotate, stirring the gypsum inside the cylinder 102 evenly. Simultaneously, the rotating shaft 302 drives the fixed rod 401 to rotate, which in turn drives the pusher plate 403 to rotate around the rotating shaft 302, pushing the gypsum towards the inner wall of the cylinder 102. The gypsum is then scraped against the inner wall of the cylinder 102 by the pusher plate 403. As the rotating shaft... The rotation of 302 drives the pusher plate 403 to squeeze the protrusion 404, thereby squeezing the gypsum between the pusher plate 403 and the protrusion 404, crushing the lumps in the gypsum, making the prepared gypsum finer. After the pusher plate 403 separates from the protrusion 404, it recovers its deformation and generates vibration, which helps to eliminate air bubbles in the gypsum. Then, when discharging, the discharge valve 602 is opened, and the connecting rod 501 drives the scraper 502 to rotate with the rotating shaft 302, so that the scraper 502 scrapes the bottom wall of the cylinder 102. The gypsum moves with the arc surface of the scraper 502 towards the rotating shaft 302, so that the gypsum is discharged through the discharge pipe 601.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
