[0002] Braces are a type of orthodontic tool, mainly used to correct the straightness of teeth. With the development of braces technology, there are more and more types of braces. The existing production of braces requires two materials, TPU and PETG, to be stacked to form three layers to prepare the braces, such as a TPU layer superimposed on a PETG layer, and then a PETG layer superimposed on the PETG layer. The current method mainly uses three screw extruders to extrude three layers of material in sequence, and then press the layers together to form a three-layer film, which is then wound, trimmed and punched to obtain the required braces product. However, when multiple extruders mix and discharge materials, the extruder structure is complex and the discharge positions are scattered. The various material layers are easily bent during the transmission and pressing process, which can easily lead to uneven thickness of the pressed layers of material, affecting the quality of the film.

In the present application, the extruder 1 2 and the extruder 2 3 are arranged side by side and the discharge ends of the extruder 1 2 and the extruder 2 3 are located on the same side. The pressing device 4 extrude and integrate the materials processed by the extruder 1 2 and the extruder 2 3 to form two layers of material. The unwinding device 5 is loaded with a third layer of material. The shaping device 6 integrates the third layer of material with the two layers of material to form a three-layer film. The trimming device 8 then trims the film, and the winding device 7 winds up the processed film. The present application integrates the two layers of material first, and then presses the third layer of material on the two layers of material, so as to reduce the possibility of bending of the material strips during the integration of the three layers of material, which may affect the quality of the film.

[0033] Reference Figure 1In this application, Extruder 1 2 is used to process TPU raw materials, and Extruder 2 3 is used to process PETG raw materials. The unwinding device 5 is placed with the processed PETG sheet, and the materials can be replaced as needed during actual use. The pressing device 4 presses the processed TPU material strips and the processed PETG material strips to form two layers of material. The pressing device 4 includes a conveying component 1 41, a conveying component 2 42, and a pressing component 43 fixedly mounted on the body 1. The conveying component 1 41 is located at the discharge end of the extruder 1 2, and the conveying component 2 42 is located at the discharge end of the extruder 2 3. The conveying component 1 41 conveys the material toward the discharge end of the conveying component 2 42 to facilitate the pressing of the two materials.

Pipe 1 (411) is sleeved over the discharge end of extruder 1 (2). After being processed by extruder 2, the material falls directly onto conveyor belt 1 (412), which drives the material. Extension pipe 413 communicates with pipe 1 (411). Conveyor belt 2 (414) is connected to the discharge end of conveyor belt 1 (412), allowing conveyor belt 2 (414) to receive material from conveyor belt 1 (412). Discharge pipe 1 (415) is connected to extension pipe 413. Discharge pipe 1 (415) houses conveyor belt 3 (9) for receiving material from conveyor belt 2 (414). The discharge pipe 415 is mainly used to merge the material processed by the extruder 2 with the material processed by the extruder 2 3. In order to improve the accuracy of the material movement path, a guide plate 10 is fixedly installed in the discharge pipe 415 on both sides of the conveyor belt 3 9 in the length direction. The guide plate 10 is tilted in this application, and the two guide plates 10 form a gradually narrowing channel, which is convenient for gradually guiding the material to move.

[0035] Reference Figure 1Conveyor assembly 2 (42) combines the material processed by extruder 2 (3) with the material processed by extruder 1 (2). Conveyor assembly 2 (42) includes a pipe 2 (421) mounted on the machine body 1 and located at the discharge end of extruder 2 (3); a conveyor belt 4 (422) installed within pipe 2 (421) and used to convey the material; a discharge pipe 2 (423) fixedly mounted at the discharge end of pipe 2 (421) and extending toward discharge pipe 1 (415); and a conveyor belt 5 (424) installed within discharge pipe 2 (423) and used to receive the material from conveyor belt 4 (422). Guide plates 2 (11) are fixedly mounted within discharge pipe 2 (423) on either side of the conveyor belt 5 (424) along its length. The two guide plates 2 (11) can be tilted to form a gradually narrowing material channel, facilitating the determination of the material discharge path. The discharge end of discharge pipe 2 (423) is symmetrically arranged with the discharge end of discharge pipe 1 (415), used to combine the two materials. In order to facilitate the merging of the two materials, in the embodiment of the present application, the discharge pipe 1 415 and the discharge pipe 2 423 are arranged to be tilted downward, so that the materials can gradually fall downward and ensure that the two materials can fit together more naturally.

[0036] Reference Figure 1 and Figure 2 After the conveying assembly 1 41 and the conveying assembly 2 42 convey the two materials and merge them, the pressing assembly 43 presses the two materials together. The pressing assembly 43 includes a connecting frame 431 fixedly mounted on the machine body 1, a protective cover 1 432 fixedly mounted on the connecting frame 431 and with its feed end sleeved over the discharge end of the first discharge pipe 415, a protective cover 2 433 fixedly mounted on the connecting frame 431 and with its feed end sleeved over the discharge end of the second discharge pipe 423, a pressing roller 1 434 mounted within the protective cover 1 432, and a pressing roller 2 435 mounted within the protective cover 2 433 and cooperating with the pressing roller 1 434. Protective cover 1 432 and protective cover 2 433 are used to protect the materials. Protective cover 1 432 is used to install pressing roller 1 434, and protective cover 2 433 is used to install pressing roller 2 435. When the two materials are discharged, they enter between pressing roller 1 434 and pressing roller 2 435, and two layers of materials are formed through the pressing of pressing roller 1 434 and pressing roller 2 435. In the present application, protective cover 1 432 and protective cover 2 433 are fixedly connected together to improve their stability. At the same time, the spaces within protective cover 1 432 and protective cover 2 433 are connected, allowing contact between pressing roller 1 434 and pressing roller 2 435. A discharge port 12 for discharging the two layers of materials is provided directly below protective cover 1 432 and protective cover 2 433, which is used to discharge the two layers of materials after pressing.

[0037] Reference Figure 2 and Figure 3After the two layers of material are processed, the unwinding device 5 conveys the pre-processed third layer of material to the shaping device 6 for three-layer film pressing. The unwinding device 5 includes a discharge roller 51 mounted on the machine body 1, a guide roller 52 mounted on the machine body 1 and located at the discharge end of the discharge roller 51, and a limit plate 53 mounted on both ends of the guide roller 52 and used to control the material movement path. The discharge roller 51 is wound with the third layer of material. The guide roller 52 is used to guide the third layer of material to the shaping device 6. The limit plate 53 is used to ensure that the delivery position of the two layers of material and the third layer of material is consistent, facilitating the lamination process of the shaping device 6. To improve the stability of the limiting plate 53 on the guide roller 52, a pressure block 13 is mounted on the inner wall of the limiting plate 53 where it contacts the guide roller 52. A movable screw 14 is fixed to the side of the pressure block 13 away from the guide roller 52. The limiting plate 53 is provided with a threaded hole 15 that fits the movable screw 14. The limiting plate 53 also has a groove 16 for the extension and contraction of the pressure block 13. To enhance the pressure effect of the pressure block 13, a rotating shaft is provided at the end of the movable screw 14 connected to the pressure block 13. The rotation of the movable screw 14 drives the pressure block 13 to move along the length of the groove 16, facilitating contact between the pressure block 13 and the guide roller 52, strengthening the stability of the connection between the guide roller 52 and the limiting plate 53, and reducing the possibility of the limiting plate 53 shifting when the guide roller 52 rotates.

[0038] Reference Figure 2 The shaping device 6 comprises several shaping rollers 61 mounted on the machine body 1 and located at the discharge end of the guide rollers 52. The third layer of material and the first and second layers of material are pressed and shaped between two adjacent shaping rollers 61, forming a three-layer film. A guide plate 17 is mounted on the machine body 1, positioned between the shaping rollers 61 and the guide rollers 52. Guide plate 17 is provided with limiting grooves 18 along the material conveying direction for positioning the material. The width of the limiting grooves 18 gradually decreases as they approach the shaping rollers 61, facilitating adjustment of the third layer's conveying position based on the positions of the first and second layers of material, thereby improving material conveying stability.

[0039] Reference Figure 2 and Figure 4After the film is laminated, it needs to be trimmed and reeled. The reeling device 7 reels the film, and the trimming device 8 cuts off the edges and corners of the film to improve the quality of the film. The reeling device 7 includes a reeling roller 71 mounted on the machine body 1, a positioning roller 72 mounted on the machine body 1 and located below the reeling roller 71, and a collecting roller 73 located at the discharge end of the machine body 1. The reeling roller 71 is located at the discharge end of the shaping device 6 and is used to reel and guide the laminated film. The positioning roller 72 improves the stability of the film transmission and facilitates the trimming device 8 to trim the film. The trimming device 8 includes a lower pressure roller 81 mounted on the machine body 1 and located between the positioning roller 72 and the collecting roller 73, a cutting table 82 mounted on the machine body 1, a cutting knife 83 mounted on the machine body 1 and located above the cutting table 82, and an adjustment component 84 mounted on the machine body 1 and used to adjust the cutting position of the cutting knife 83. The cutting table 82 is located below the lower pressing roller 81. The lower pressing roller 81 presses the film downward to contact the cutting table 82, facilitating the cutting of the film edges by the cutting blade 83. A waste roller 19 is also installed on the machine body 1 between the collecting roller 73 and the cutting table 82. The waste roller 19 is used to collect the cut scraps.

[0040] Reference Figure 4 The adjustment assembly 84 includes a plurality of positioning rods 841 mounted on the body 1 and a positioning ring 842 that is sleeved on the positioning rods 841 and is used to position the cutting blade 83. The positioning rods 841 are provided with a slide groove 20 along their length. A slider 21 located within the slide groove 20 is fixed to the inner wall of the positioning ring 842. The cutting blade 83 is fixed to the bottom end of the positioning ring 842. An adjustment screw 22 located within the slide groove 20 is mounted on the positioning rod 841. The slider 21 sleeves on the adjustment screw 22 and is threadedly connected to the adjustment screw 22. A motor for driving the adjustment screw 22 to rotate is fixed to the positioning rod 841. The rotation of the adjustment screw 22 drives the slider 21 to move along the length of the slide groove 20. The threaded connection between the slider 21 and the adjustment screw 22 can also effectively prevent the positioning ring 842 from shifting in position when the cutting blade 83 is cutting.

[0041] The implementation principle of a braces production line in an embodiment of the present application is as follows: Extruder 1 2 processes TPU raw material to form a first material, Extruder 2 3 processes PETG raw material to form a second material, and the unwinding device 5 places a well-processed PETG sheet as a third material. Conveying component 1 41 conveys the first material toward the second material, conveying component 2 42 conveys the second material to the discharge end of conveying component 1 41, and the pressing device 4 presses the first material and the second material to form two layers of material. The two layers of material are directly discharged to the shaping device 6, and the unwinding device 5 conveys the third material to the shaping device 6 to merge with the two layers of material, and then the shaping device 6 processes the third material to form a three-layer film. After the three-layer film is pressed together, the trimming device 8 cuts the uneven position of the film corner material, and then the cut film is rolled up by the winding device 7, which facilitates the subsequent processing of the film. This application effectively reduces the installation space of the extruder, reduces the possibility of skew during material transmission, which affects the pressing of the material, improves the film processing quality, and thus facilitates subsequent stamping processing and improves the quality of the braces.
