Description

Technical Field

[0001] The utility model relates to the field of denture manufacturing and processing, in particular to a gypsum finishing machine. Background Art

[0002] During the denture manufacturing process, a plaster trimming machine is needed to polish the plaster model of the denture in order to produce a denture model that meets the requirements. The trimming machine is connected to the faucet to prevent the dust generated by the grinding of the plaster model from flying around and endangering the environment and human health. Part of the dust and sewage that have been treated with water flows into the collection tank from the filter holes on the surface of the trimming table.

[0003] Usually when grinding a plaster model of a denture, it is necessary to place the model on a finishing table, hold the model with your hands, and rotate the model to adjust its angle so that it can be evenly ground.

[0004] Sometimes the model needs to be tilted for polishing. At this time, the horizontal trimming table cannot support the model well. The force exerted by the trimming machine on the model makes it impossible for the worker to hold the plaster stably, thus affecting the polishing. Utility Model Content

[0005] The utility model aims to provide a gypsum trimming machine, which has the advantage of being able to adjust the angle of a trimming table so as to better support the gypsum model.

[0008] By adopting the above technical solution, the support plate is rotated, and then the rotating shaft is rotated. The rotating shaft drives the rotating wheel to rotate through the connecting rod, so that the rotating wheel contacts the bottom surface of the support plate. The rotating shaft will not rotate back under the action of the ratchet and the pawl, thereby supporting the support plate, so that the rotating shaft can be rotated at different angles, and the inclination of the support plate can be changed to better support the plaster model. The pawl is rotated to separate it from the ratchet, and then the rotating shaft is rotated back, and the support plate returns to its original position.

[0009] Preferably, a knob is fixedly connected to the end of the rotating shaft, a handle is fixedly connected to the rotational connection between the ratchet and the collecting slot, and the knob and the handle are located outside the collecting slot.

[0010] By adopting the above technical solution, the knob and the handle are used respectively to facilitate the rotation of the shaft and the pawl.

[0011] Preferably, it further comprises a protective shell, wherein the protective shell is fixedly connected to the collecting tank, the rotating shaft passes through the protective shell, and the ratchet and pawl mechanism is located inside the protective shell.

[0012] The above technical solution is adopted to prevent the ratchet pawl from being damaged from the outside.

[0013] Preferably, two opposite back plates are fixedly connected at the trimming port of the trimming machine, and clamping grooves are fixedly connected on both sides of the outer wall of the collecting groove. The collecting groove is located between the two back plates, and the back plates are provided with grooves for the knob and the handle to pass through. The edges of the back plates are embedded in the clamping grooves, and the collecting groove and the back plates are detachably connected.

[0014] By adopting the above technical solution, the collecting tank can be removed from the finishing machine, so that the inside of the collecting tank can be easily cleaned.

[0015] Preferably, the support plate is threadedly connected with a clamping bolt, and an end of the clamping bolt is in contact with the collecting tank.

[0016] The above technical solution is adopted to better fix the collecting tank. BRIEF DESCRIPTION OF THE DRAWINGS
