Description

Technical Field

[0001] The present invention relates to the technical field of orthodontics, and specifically to a pretreatment device for polymer materials for orthodontic teeth. Background Art

[0002] Synthetic polymer materials mainly refer to the three major synthetic materials of plastics, synthetic rubbers and synthetic fibers. The dental gum sleeves made of synthetic polymer materials have the characteristics of high wear resistance and strong corrosion resistance, and should be applicable to the field of orthodontics. During the orthodontic process, it is necessary to position the teeth to be corrected, and usually a dental gum sleeve needs to be worn. Before the dental gum sleeve is used, that is, during the manufacturing process, it is necessary to polish the rubber pad on the dental gum sleeve. In order to make the rubber pad more conform to the oral cavity and the user more comfortable when wearing, the usual polishing method requires manual holding of the dental gum sleeve blank and cooperation with a polishing device for polishing. The polishing time is long and the polishing is not accurate enough, resulting in the arc surface curvature of the rubber pad surface not being smooth enough, causing discomfort when wearing. In view of the above problems, the inventor proposes a pretreatment device for polymer materials for orthodontic teeth to solve the above problems. Summary of the Invention

[0041] Working principle: The material of the rubber pad 81 is a polymer material, namely synthetic rubber. The rubber pad 81 is bonded to the connecting strip 83 on the fastening strip 82, thus forming the blank of the dental gum sleeve 8. Before orthodontics, the rubber pad 81 needs to be ground and pre-treated into an arc surface. When grinding, the fastening strip 82 is clamped and installed in the four C-shaped sleeves 73, so as to conveniently and quickly fix and install the blank of the dental gum sleeve 8. The output end of the second motor 31 drives the second gear 32 and the first bevel gear 33 to rotate, and drives the second bevel gear 34 and the fourth gear 37 to rotate, so that the grinding wheel 38 rotates closely against the arc surface of the rubber pad 81. The two second gears 32 drive the corresponding fifth gears 45 to rotate, and then the upper grinding shaft 41 and the lower grinding shaft 42 rotate on both side surfaces of the rubber pad 81 through the fourth rotating shaft 44. The output end of the first motor 21 drives the turntable 22 to rotate, so that the vertical shaft 24 drives the sector gear 23 to swing, and makes the first gear 26, the second rotating shaft 27 and the L-shaped rotating plate 51 rotate reciprocally. Thus, the second motor 31, the upper grinding shaft 41 and the lower grinding shaft 42 installed on the L-shaped seat 311 can rotate around the second rotating shaft 27 as the center. The rotation of the L-shaped rotating plate 51 makes the fifth rotating shaft 62 drive the sixth gear 61 to rotate along the arc-shaped tooth block 63, and makes the seventh gear 64 drive the two racks 52 to slide reversely. Then, the rotation inclination angles of the upper grinding shaft 41 and the lower grinding shaft 42 installed with the universal joint 43 are changed, so that the two side surfaces of the rubber pad 81 can be ground into an arc shape at the same time.
