Description

Technical Field

[0002] Root canal therapy, also known as endodontic treatment, is a dental procedure for treating pulp necrosis and root infection. This procedure preserves the tooth, thus complementing tooth extraction. Root canal therapy requires a set of fine and flexible root canal files to clean and shape the root canal. The dentist rotates and pulls the file in the root canal with a hand file or a machine file connected to a motor. During the root canal rotation and lifting operation, the root canal file penetrates deep into the root canal and cuts off the diseased part on the way.

[0003] Root canal files are essential for root canal preparation in root canal treatment technology. Root canal files need to be polished with a grinding wheel during processing, and a taper and thread need to be polished at the root canal. With the development of modern medicine, medical equipment is becoming more and more sophisticated, and there are more and more models of root canal files, with smaller and smaller sizes and higher and higher precision requirements. The currently commonly used root canal file grinding device is fed through a wire disc, and the wire disc is usually placed horizontally around the grinding equipment.

In the preparation, it affects the moving accuracy of the grinding component 3, further affecting the yield rate of the file needle processing. The wire drawing component 2 is provided with a guide tube 22 structure to guide the file wire into the extrusion push rod 25, so as to avoid rotational deviation during the file wire feeding process, affecting the moving path of other motion mechanisms. The semi-suspended wire feeding component 4 adopts a vertically arranged wire disc 44 structure, and the rotation angle of the wire disc 44 is adjusted by a rotatable rotating disc 45 structure. The rotation angle of the wire disc 44 is adjusted during the wire feeding process to reduce the trajectory deviation of the file wire caused by rotation. At the same time, the file wire is rotated during the grinding process and the file wire is rotationally processed. The limit block structure arranged under the wire disc 44 stops the wire disc 44 through friction after the wire feeding operation is completed, so as to reduce the excessive release of the file wire due to the inertial sliding of the wire disc 44.

[0030] In this embodiment, the wire drawing assembly 2 includes a wire drawing seat 21, a guide tube 22, a wire filing adjustment member 23, an adjustment wheel 24, an extrusion push rod 25, an extrusion push drive device 26 and a positioning member 27.

The wire feeding drive device 41 is used to adjust the rotation angle of the wire disc 44, and the adjustment range is 0-90 degrees. The angle position of the rotating wire disc 44 ensures that the wire feeding process remains stable and smooth.

[0036] In this embodiment, the chassis 1 is provided with an upper box body 11 and a lower box body 12, the upper box body 11 is fixedly connected to the lower box body 12, a partition 111 is formed in the middle of the upper box body 11, one side of the partition 111 is the processing chamber 5, and the other side of the partition 111 is the installation chamber 112, the partition 111 is formed with an air vent 113, the recovery component 6 is connected with the processing chamber 5 through the air vent 113, and a discharge hole 114 is formed on one side of the upper box body 11.

[0039] Working principle of the present invention:

[0040] Before starting the machine, pass the file through the wire drawing assembly 2, and pass the active end of the file through the file grinding fixture 29 to form a stable file moving track. The staff adjusts the horizontal installation angle and inclination of the grinding member 35 according to the grinding requirements of the product;

[0041] The sliding door is closed, and the positioning drive device 272 located in the processing chamber 5 is pushed out to press the wire on the extrusion block 273 to a limit position. The wire drawing assembly 2 pulls the extrusion push rod 25 to clamp the wire through the extrusion push drive device 26. Then the positioning drive device 272 resets and rises to end the pressing limit position. The extrusion push rod 25 resets under the action of the spring to push the wire forward. At this time, the wire reel 44 of the semi-suspended wire feeding assembly 4 is rotated under force, and the wire feeding drive device 41 under the wire reel 44 rotates 90 degrees during the wire feeding process to ensure that the wire is fed along the wire reel 4. 4, and the wire flows upward. After the wire feeding process is finished, the wire feeding drive device 41 rotates to drive the rotating disk 45 to reset. Under the action of the pushing friction of the limit block, the wire disk 44 is stopped. After the file is pushed out, the processed file needle is pushed out to the feeding plate 7. The unprocessed file end is processed by the grinding member 35 under the adjustment of the first driving device 31, the second driving device 32 and the angle adjustment device 33 of the grinding assembly 3. The file adjusting member 23 rotates to adjust the rotation angle of the file, thereby realizing the circumferential grinding of the file.

[0042] The oil-gas mixture generated during the processing is recovered by the exhaust fan 61 in the processing chamber 5 to the oil guide groove 125 through the ventilation holes, and the condensed oil flows out from the oil outlet hole 122 along the oil receiving groove 121.
