Description

Technical Field

[0001] The utility model belongs to the technical field of positive and negative film pressing machines, in particular to a positive and negative film pressing machine. Background Art

[0002] Traditional dental laminators mostly use pure positive pressure or pure negative pressure to laminat the model, and are widely used in the dental field.

[0003] The existing pure negative pressure laminating machine is limited by the internal vacuum components, resulting in a relatively low pressure during negative pressure molding, so that the degree of fit between the diaphragm and the model cannot fully meet the molding requirements. The pure positive pressure laminating machine can be connected to an external air pump to make its pressure sufficient to meet the requirements and can also better fit the diaphragm to the model. However, due to the limitation of its pressure direction, it is easy to form air cavities when laminating models with large pits and grooves, affecting the molding quality of the diaphragm. Therefore, we proposed a positive and negative laminating machine. Utility Model Content

It solves the problem that the existing pure negative pressure laminating machine makes it impossible for the fit between the diaphragm and the model to fully meet the forming requirements, and the pure positive pressure laminating machine is limited by its pressure direction, which makes it easy to form air cavities when laminating a model with large grooves, thereby affecting the quality of diaphragm forming.

[0039] A specific application of this embodiment is:

[0040] First, place the dental membrane on the top of the negative pressure platform 131, and then place the diaphragm on the turntable 141. The diaphragm is positioned by the positioning block 413, and both square and circular diaphragms can be placed. After the placement is completed, the cover plate 142 is placed on the top of the turntable 141, so that the positioning block 413 enters the positioning groove 422, which is used to position the cover plate 142. This way of placing the diaphragm can avoid the diaphragm being connected to the cover plate first, thereby preventing the diaphragm from falling off. After the placement is completed, the gear 152 is driven to rotate by starting the motor 151. The gear 152 drives the connecting block 411 to rotate under the action of the external teeth 412, and the turntable 141 rotates to the bottom of the heating module 122. The diaphragm is heated by the heating module 122, and the turntable 141 is driven to rotate by the motor 151, which can reduce the number of times the staff contacts the turntable 141, and avoid overheating of the turntable 141 when used too many times, causing burns to the staff.

[0041] After the heating is completed, the gear 152 is turned over by starting the motor 151, and the turntable 141 is rotated to the top of the negative pressure platform 131. The negative pressure platform 131 is moved upward by the controller 11, and the connecting block 411 slides on the vertical rod 123 and leaves the gear 152. The movement of the negative pressure platform 131 makes the diaphragm contact with the dental membrane. At the same time, the top of the negative pressure platform 131 is plugged into the ring 1 415, and drives the turntable 141 and the cover plate 142 to move upward, so that the ring 2 421 is plugged into the bottom of the positive pressure platform 121. Through the socket connection between the ring 1 415 and the ring 2 421, the sealing block 132 can be squeezed, and the slider 323 moves in the fixed block 322 and squeezes the spring 324, and then the sealing block 132 is elastically moved with the ring 1 415 and the ring 2 421. 1 is close to improve the sealing effect, a large amount of gas is released from the air chamber in the positive pressure platform 121 to form positive pressure, and the vacuum pump in the negative pressure platform 131 is started to extract the gas in the air chamber in the negative pressure platform 131 to form negative pressure, and the film pressing work is completed. By combining the positive pressure and negative pressure film pressing methods, the pressure is guaranteed while the air in the internal cavity of the diaphragm is sucked away, thereby improving the quality of diaphragm forming and avoiding the formation of air cavity. Finally, after the film pressing is completed, the negative pressure platform 131 is reset, and the turntable 141 is reset together. When the connecting block 411 moves to the top of the gear 152, the outer teeth 412 on the connecting block 411 are meshed and connected with the gear 152 by slightly adjusting the handle 1 414, and then the cover plate 142 is pulled upward and taken out by the handle 2 423, and the diaphragm can be taken out.
