Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1-5 As shown, the embodiment of the utility model provides a positive pressure dental laminator, comprising: a base bin 1, wherein a reserved cavity is opened in the middle of the top of the base bin 1, a hollow cushion seat 2 is welded on the top of the base bin 1 and located on the outer edge of the reserved cavity, and a mesh plate 3 is installed on the top of the hollow cushion seat 2 by screws;

[0029] A diaphragm clamping assembly 7 for clamping the diaphragm is installed inside the base bin 1, and the movable end of the diaphragm clamping assembly 7 is located above the base bin 1;

[0030] An L-shaped frame 4 is welded to the back of the base bin 1, and electric telescopic rods A5 are installed at the four corners of the top of the L-shaped frame 4, and a heating and pressing assembly 6 for heating and pressing the diaphragm is fixedly connected between the movable ends of the four electric telescopic rods A5.

[0031] An air collecting bin 9 is welded to the top of the inner wall of the base bin 1 and just below the reserved cavity. A vacuum pump 8 is installed inside the base bin 1, and the air intake of the vacuum pump 8 is connected to the air outlet at the bottom of the air collecting bin 9 through a pipeline.

[0032] The diaphragm clamping assembly 7 includes four electric telescopic rods B71 installed at the four corners inside the base bin 1, and the movable ends of the electric telescopic rods B71 are located at the top of the base bin 1. A lower hollow frame 73 is fixedly connected between the movable ends of the four electric telescopic rods B71. The top of the lower hollow frame 73 is clamped with an upper hollow frame 75. A limiting groove 77 is provided on the inner edge of the top of the lower hollow frame 73. The limiting groove 77 serves to limit the position of the diaphragm to prevent the diaphragm from being movable after being clamped, thereby ensuring that the diaphragm will not move when it is pressed with the tooth model, which is conducive to the diaphragm to fully contact the tooth model.

[0033] The four corners of the top of the lower hollow frame 73 are welded with positioning rods 74, and the four corners of the bottom of the upper hollow frame 75 are penetrated with positioning holes 76 that are compatible with the positioning rods 74. The clamping connection between the positioning rods 74 and the positioning holes 76 can realize the positioning of the lower hollow frame 73 and the upper hollow frame 75, ensuring that the upper hollow frame 75 presses the diaphragm at all times.

[0034] The four sides of the outer wall of the lower hollow frame 73 are bonded with hollow rubber frames 72 , and the height of the hollow rubber frame 72 is higher than that of the lower hollow frame 73 , wherein the bottom end surface of the hollow rubber frame 72 is located below the bottom end surface of the lower hollow frame 73 .

[0035] The heating and pressing assembly 6 comprises a lifting plate 61 installed at the movable end of the electric telescopic rod A5, a translation plate is slidably installed at the bottom of the lifting plate 61, and a pressing body 66 and a heating body 67 are respectively installed on both sides of the bottom of the translation plate.

[0036] T-shaped guide rails 63 are installed on both sides of the top of the translation plate, and a T-shaped slider 62 is slidably installed in the slide groove of the T-shaped guide rail 63. At the same time, the top of the T-shaped slider 62 is welded to the bottom of the lifting plate 61, and a rack 65 is installed in the middle of the top of the translation plate. A servo motor 64 is installed on the top of the lifting plate 61, and a gear meshing with the rack 65 is installed on the driving end of the servo motor 64.

[0037] The heating body 67 includes a left side frame 671 installed at the bottom of the translation plate, and the bottom of the left side frame 671 is open. The top of the inner wall of the left side frame 671 is installed with an infrared mounting seat 672 through a mounting column. A plurality of infrared heating tubes 673 are installed in the inner cavity at the bottom of the infrared mounting seat 672. The medium-wave infrared heating of the diaphragm is achieved by the infrared heating tubes 673. The medium-wave infrared heating does not require preheating, and not only heats the surface of the material, but also can penetrate into the entire material. The model can be adjusted during heating, and the lifting plate 61 is driven downward by the extension of the electric telescopic rod A5 to move the heating body 67 to the diaphragm. Above the clamping assembly 7, that is, the heating body 67 is located above the diaphragm, and medium-wave infrared heating of the diaphragm is achieved through an infrared heating tube 673. Medium-wave infrared heating does not require preheating, and not only heats the surface of the material, but also penetrates into the entire material. The model can be adjusted during heating. The four corners of the top of the infrared mounting seat 672 are penetrated by perforations 674, and temperature sensors 675 are installed on the top of the infrared mounting seat 672 and directly above each perforation 674. The four temperature sensors 675 detect the temperature of the diaphragm from the four corners of the diaphragm, so that the temperature of the diaphragm itself is obtained more accurately.

[0038] The downward pressing body 66 includes a right side frame 661 installed at the bottom of the translation plate, and the bottom of the right side frame 661 is open. The top of the inner wall of the right side frame 661 is fixedly connected to a sealing frame 662 through a mounting column, a sealing gasket 663 is bonded to the bottom of the sealing frame 662, and an air supply hole 664 is opened through the middle of the top of the sealing frame 662. The air supply end of the positive pressure compressor is fixedly connected to the air inlet end of the air supply hole 664, and a ventilation hole is opened on one side of the right side frame 661.

[0039] When the diaphragm is pressed, the bottom of the hollow rubber frame 72 fits with the upper surface of the base bin 1 to ensure the sealing performance between the lower hollow frame 73 and the base bin 1. At the same time, the sealing gasket 663 is pressed on the top of the upper hollow frame 75. On the one hand, it ensures the downward pressure on the diaphragm so that the diaphragm can fully fit with the tooth model. On the other hand, it also ensures the sealing performance between the sealing gasket 663 and the upper hollow frame 75, so that when the diaphragm is pressed, the space where the diaphragm is located is relatively sealed, which can improve the fit between the diaphragm and the tooth model.

[0040] The working principle of the utility model is:

[0041] When in use, the diaphragm is mounted on the diaphragm clamping assembly 7, and the process is as follows:

[0042] The electric telescopic rod B71 extends to drive the lower hollow frame 73 to move upward, and the upper hollow frame 75 is held and lifted up, so that the upper hollow frame 75 is moved out from the top of the lower hollow frame 73, and the diaphragm is placed inside the limiting groove 77. Then, the upper hollow frame 75 is placed on the top of the lower hollow frame 73. At this time, the positioning rod 74 enters the interior of the upper hollow frame 75 for clamping, and presses the diaphragm between the lower hollow frame 73 and the upper hollow frame 75.

[0043] After the film is clamped, the tooth model is placed in the middle of the upper surface of the mesh plate 3;

[0044] The driving gear 54 rotates, and the heating body 67 is moved to the top of the diaphragm under the meshing transmission of the gear and the rack 65, and the lifting plate 61 is driven downward by the extension of the electric telescopic rod A5, and the heating body 67 is moved to the top of the diaphragm clamping assembly 7, that is, the heating body 67 is located above the diaphragm, and the medium-wave infrared heating of the diaphragm is realized by the infrared heating tube 673;

[0045] After the diaphragm temperature is reached, the electric telescopic rod A5 shortens, moves the heating body 67 upward, and controls the gear on it to rotate again through the servo motor 64, moves the pressing body 66 to be directly above the diaphragm, and then, the electric telescopic rod A5 extends to press the sealing gasket 663 on the upper surface of the upper hollow frame 75. At this time, the electric telescopic rod A5 continues to extend, and the electric telescopic rod B71 shortens, so that the hollow rubber frame 72 fits with the upper surface of the base bin 1, and then the vacuum pump 8 is turned on to vacuum the cavity where the diaphragm is located through the air collecting bin 9. At the same time, the positive pressure compressor continuously delivers airflow to the cavity where the diaphragm is located through the air supply hole 664, thereby achieving pressure between the diaphragm and the tooth model.
