Description

Detection device for dental diaphragm Technical Field The application relates to the technical field of dental diaphragms, in particular to a detection device for a dental diaphragm. Background Dental diaphragms are an important raw material for the fabrication of bracket-free dental appliances, which are typically pressed onto tooth models using dental diaphragms with high transparency. The hot pressing principle is that the dental diaphragm is heated and softened at high temperature before film pressing, the softened diaphragm is wrapped on the surface of a rapidly formed resin tooth model by utilizing gas pressure after heating, then cooling, diaphragm separation and cutting processes are carried out, the formed dental diaphragm can be used for trimming details by scissors for dental treatment such as teeth correction, and the traditional invisible dental sleeve is made of the diaphragm. At present, no corresponding detection equipment in the industry can directly test the correction force of the bracket-free dental appliance, and no corresponding detection equipment can simulate the oral environment and directly test the stress retention performance of the dental diaphragm. More in terms of performance, the selection is based on the relevant properties in terms of the physical properties of the transparent elastic material. However, when the transparent elastic material is processed to obtain the dental film, the performance of the dental film may be changed, and the performance of the dental film may directly affect the orthodontic ability of the bracket-free dental appliance. Therefore, it is desirable to provide a test device that can simulate the oral environment and directly test the performance of a dental diaphragm. Disclosure of utility model In order to be able to detect the performance of a dental diaphragm, the application provides a device for detecting a dental diaphragm. The application provides a detection device for a dental diaphragm, which adopts the following technical scheme: The utility model provides a detection device of dentistry diaphragm, includes that the cooperation sets up last dental cast and lower dental cast, all overlaps on the tooth of last dental cast and lower dental cast and is equipped with the dentistry diaphragm to on last dental cast compresses tightly lower dental cast, lets two sets of dentistry diaphragms can extrude each other, still including the control assembly who is used for controlling last dental cast and removes on lower dental cast, control assembly is including connecting the actuating lever on last dental cast and the driving piece that the drive control lever removed, lets last dental cast carry out the removal on the horizontal direction on lower dental cast. Through adopting above-mentioned technical scheme, because the dental diaphragm of production needs to be installed on patient's tooth, convenient at ordinary times eat etc. can cause the dental diaphragm on upper tooth and the lower tooth to rub each other, therefore, when examining the dental diaphragm performance of production, install the dental diaphragm that waits to detect on the dental mould that corresponds, the driving piece that sets up through, the removal of drive control lever, the control lever can control the upper tooth mould and remove in the horizontal direction in the removal process, thereby let the dental diaphragm on the upper tooth mould rub with the dental diaphragm on the lower tooth mould, observe the life cycle of dental diaphragm through long-time friction, when the dental diaphragm grinds the damage, obtain the live time of dental diaphragm, thereby obtain the performance of dental diaphragm. Preferably, the driving piece comprises a driving motor and a driving turntable, the driving motor controls the driving turntable to rotate, the end part, far away from the upper dental cast, of the control rod is connected to the driving turntable and is close to the edge, and the control rod is connected with the driving turntable in a rotating mode. Through adopting above-mentioned technical scheme, the drive motor that sets up can drive pivoted rotation, and the tip and the drive carousel of control lever rotate to be connected, and the drive carousel is at the rotation in-process, can drive the removal of control lever to drive the removal of tooth mould, adopt driving motor to have the advantage that the response is rapid, and can adjust the travel speed of control lever, can detect the life of tooth diaphragm in the short time. Preferably, the end part of the control rod, which is far away from the upper dental model, is fixedly provided with a guide rod which is arranged along the length direction of the control rod, the guide rod is provided with a guide hole which is arranged along the length direction of the guide rod, the surface of the driving turntable is fixedly provided with a driving block, and the driving block is in sliding fit in the guide hole.
