Description

Technical Field

[0001] The utility model relates to the technical field of dental appliances, in particular to a film-making and laminating machine for dental appliances. Background Art

[0002] Dental braces are a common dental treatment device used to correct abnormal tooth alignment and bite problems. Film laminating machine is one of the important equipment used to make dental braces. Its function is to process the plastic material (usually polymer) required for the braces into a laminating film that fits the shape of the patient's teeth to ensure the fit and comfort of the braces.

[0003] The Chinese patent with publication number CN218876248U discloses a film laminating machine for invisible dental braces. It can fix tooth models of different models and sizes by adjusting the cooperation of screws, drive blocks, connecting plates, support rods and fixing plates, so as to prevent the tooth models from being displaced during the laminating process, ensure that the tooth models will not be displaced during the laminating process, and ensure the accuracy of the braces. The forming sheet can be simply and conveniently fixed by the cooperation of the fixing card and the fixing rod, which is convenient for processing. The exhaust hole can facilitate the forming sheet to be better and faster formed when the placement frame is connected to the lower splint.

[0004] With respect to the above-mentioned related technologies, the device has some shortcomings. In actual use, it is necessary to manually place the forming sheet between the upper splint and the lower splint, and manually adjust the vertical position of the splint to complete the laminating operation on the tooth model. This manual operation method is not convenient enough, and it requires the user to spend more time and energy to ensure that the forming sheet is correctly placed and pressed in place. Therefore, it is necessary to provide a film laminating machine for dental braces to solve the above technical problems. Utility Model Content

[0027] See also Figure 1-4 , an embodiment provided by the utility model:

[0028] A film laminating machine for a dental appliance, comprising:

[0029] The laminator body 1 has limit rods 2 fixedly installed on both sides of the top of the laminator body 1, a top plate 5 fixedly installed on the top of the limit rod 2, a driving mechanism is arranged on the top of the top plate 5, symmetrically distributed threaded rods 3 are rotatably installed between the bottom of the top plate 5 and the top of the laminator body 1, and an upper clamping plate 4 is sleeved on the outer wall of the threaded rods 3;

[0030] The top of the upper clamping plate 4 is provided with symmetrically distributed fixing holes 14, and a positioning rod 9 is slidably inserted into the fixing hole 14. The bottom end of the positioning rod 9 is fixedly installed with the lower clamping plate 8, and a stopper 13 is provided at the top of the positioning rod 9. A spring 10 is sleeved on the outer wall of the positioning rod 9 between the stopper 13 and the top of the upper clamping plate 4.

[0031] The driving mechanism includes a fixed box 6, and the fixed box 6 is fixedly installed on the top of the top plate 5. The top end of the threaded rod 3 passes through the bottom of the top plate 5 and extends to the inside of the fixed box 6 and is rotatably connected to the bearing installed on the top of the inside of the fixed box 6. A worm gear 12 is fixedly installed on the outer wall of the top end of the two threaded rods 3. A worm 11 is rotatably installed inside the fixed box 6, and the worm 11 is meshed with the worm wheel 12. A motor 7 is fixedly installed on one side of the fixed box 6, and the driving end of the motor 7 passes through one side of the fixed box 6 and extends to the inside of the fixed box 6 and is fixedly connected to one end of the worm 11.

[0032] In one of the embodiments, the stopper 13 is fixed to the top end of the positioning rod 9 by means of bolts, so that the stopper 13 is detachable and the spring 10 on the positioning rod 9 is easily replaced.

[0033] In one preferred embodiment, the top of the upper clamping plate 4 is provided with threaded holes corresponding to the positions and the number of the threaded rods 3 , and the upper clamping plate 4 is threadedly connected to the threaded rods 3 through the threaded holes provided on the top thereof.

[0034] In one of the embodiments, a sliding hole corresponding to the position and number of the limit rod 2 is opened on the top of the upper clamp 4, and the upper clamp 4 is slidably connected to the limit rod 2 through the sliding hole opened on its top to ensure the stability of the upper clamp 4 during vertical movement.

[0035] In one preferred embodiment, the specifications and sizes of the two threaded rods 3 are consistent to ensure that they have consistent functions and performances in the film pressing device. Such a consistent design helps to ensure the synchronization between the two threaded rods 3 during the vertical movement of the upper clamping plate 4.

[0036] The working principle of the utility model is as follows: when in use, the tooth model is placed in the processing area at the top of the laminating machine body 1, and then the motor 7 is controlled to start working. The driving end of the motor 7 drives the worm 11 to rotate, and the meshing of the worm 11 and the worm wheel 12 makes the two worm wheels 12 rotate at the same time. The rotation of the worm wheel 12 drives the two threaded rods 3 to rotate, and the threaded transmission of the threaded rod 3 and the upper clamping plate 4, as well as the sliding relationship between the upper clamping plate 4 and the limiting rod 2, makes the upper clamping plate 4 stably move vertically, and the movement of the upper clamping plate 4 drives the lower clamping plate 8 to move, first making the upper clamping plate 4 and the lower clamping plate 8 move up, and the movement of the lower clamping plate 8 drives the positioning rod 9 and the stopper 13 to move, and the stopper 13 will contact the bottom of the top plate 5 during the upward movement. At this time, the stopper 13 and the positioning rod 9 are hindered by the top plate 5 and cannot continue to move up. At this time, the upper clamping plate 4 will slide upward on the outer wall of the positioning rod 9 and squeeze the spring 10, and at the same time, the upper clamping plate 4 is separated from the lower clamping plate 8, and then the staff will form The mold piece is placed on the top of the lower clamping plate 8, and then the upper clamping plate 4 is controlled to move downward. The upper clamping plate 4 will first slide up and down on the outer wall of the positioning rod 9 and contact the top of the lower clamping plate 8 to clamp and fix the molded piece. At this time, the lower clamping plate 8 will be firmly attached to the bottom of the upper clamping plate 4 under the elastic action of the spring 10 to ensure the firmness of the molded piece. Subsequently, the lower clamping plate 8 will move down together with the downward movement of the upper clamping plate 4, and finally press the molded piece clamped between the lower clamping plate 8 and the fixing hole 14 onto the tooth model, and then be heated by the vacuum machine heater so that the molded piece can be better shaped along the tooth model. After the plasticization is completed, the tooth model and the molded piece are a whole, and will move up with the upper clamping plate 4 and the lower clamping plate 8. As the upper clamping plate 4 and the lower clamping plate 8 move up to a certain height, the two are automatically separated, and the molded piece and the tooth model located on the top of the lower clamping plate 8 can be taken out. In the entire lamination process, the vertical movement of the upper clamping plate 4 and the lower clamping plate 8 is achieved by mechanical drive. When the upper clamping plate 4 and the lower clamping plate 8 are raised to the specified position, they will automatically separate; and when they are lowered to the specified position, they will automatically close. This automated design allows the staff to complete the material discharge and material collection when the upper clamping plate 4 and the lower clamping plate 8 are automatically separated, without manual operation. Such improvements improve the convenience of use, save manpower, and speed up work efficiency.

[0037] During operation, the device is driven by the motor 7 to rotate the worm 11, which can synchronously drive the two worm wheels 12 to rotate. Since the transmission mechanism of the worm and the worm wheel has good synchronization, the lifting process of the upper clamping plate 4 can be ensured to be smooth and reliable.

[0038] The entire device is controlled by a main control button. Since the device matched with the control button is a commonly used device and belongs to the existing common knowledge technology, its electrical connection relationship and specific circuit structure will not be described here. In addition, the parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
