[0028] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Reference Figures 1-9 This utility model provides a special synchronous belt for prosthetic teeth, including a base belt body 1. The inner surface of the base belt body 1 is provided with a plurality of equally spaced tooth profiles 2. The base belt body 1 is provided with two symmetrically distributed avoidance areas 4 along the length direction. Multiple sets of positioning holes 101 are opened inside the base belt body 1 and at the position of the avoidance area 4. The tooth profiles 2 corresponding to the positioning holes 101 are replaced with prosthetic teeth 5. The prosthetic teeth 5 are set in the same shape as the tooth profiles 2. The top of the prosthetic teeth 5 has two positioning bosses 6 integrally formed, and the positioning bosses 6 are inserted and installed into the positioning holes 101. Multiple uniformly distributed reinforcing steel wires 3 are embedded inside the baseband body 1, and the reinforcing steel wires 3 and the avoidance area 4 do not interfere with each other.

[0030] Specifically, the production process of synchronous belts is as follows: S1: Polyurethane and reinforcing steel wire 3 are fused together by centrifugal casting using a special mold to produce the base belt body 1. The base belt body 1 can be further processed by cutting, milling, and drilling according to actual length requirements. It can be spliced ​​into a ring belt by heating the mold. S2: During casting, a special mold is used to reasonably avoid the reinforcing steel wire 3, which ensures tensile strength while facilitating the "installation position" of the denture 5 in the later processing.

[0031] The "installation position" is the location of the original tooth type 2. The dummy tooth 5 is then installed in the "installation position" and the original tooth type 2 is replaced.

[0032] In addition, the top outer edge of the positioning boss 6 is chamfered, the positioning boss 6 is a through structure, and the interior of the positioning boss 6 is provided with a locking component for assembly and fixation. The locking component includes a connecting thread 601, which is formed inside the positioning boss 6.

[0033] Therefore, the positioning boss 6 provided on the top of the false tooth 5 is fastened into the positioning hole 101 opened in the baseband body 1. When installing and locking, it can be assembled by screws and connecting threads 601 opened inside the positioning hole 101.

[0034] As an alternative implementation of the solution: Since the screw and connecting thread 601 are prone to thread damage after prolonged use, requiring replacement of the entire false tooth 5, an alternative locking connection method is designed. This locking connection method uses a threaded sleeve 602 (e.g., Figures 8-9 As shown), the top of the threaded sleeve 602 has a slot, and the inside of the positioning boss 6 has an installation groove 603. The installation groove 603 is threadedly connected to the threaded sleeve 602. Therefore, the service life of the denture 5 can be increased by replacing the threaded sleeve 602.

[0035] The threaded insert 602 is made of wear-resistant stainless steel, and its outer surface has precision threads that match the mounting groove 603, ensuring a stable connection when screwed in and preventing loosening. During installation, the operator needs to align the threaded insert 602 with the mounting groove 603 inside the positioning boss 6 and tighten it clockwise with a special tool until the preset torque value is reached, ensuring reliable fixation of the dummy tooth 5 on the baseband body 1. When the threads of the threaded insert 602 wear or are damaged due to prolonged use, the old part can be unscrewed counterclockwise and a new threaded insert 602 can be quickly replaced without disassembling or replacing the entire dummy tooth 5 assembly, significantly reducing maintenance time and spare parts costs. In addition, the depth and diameter of the mounting groove 603 have been optimized, leaving sufficient space for the threaded insert 602 to expand and contract, adapting to changes in thermal expansion and contraction under different working conditions, further improving the durability and adaptability of the system.

[0036] To improve the stability of the prosthesis 5 after assembly (such as...) Figures 6-7 As shown in the figure, in this utility model, the top of the false tooth 5 is provided with at least three fastening mounts 501, the three fastening mounts 501 and the positioning boss 6 are staggered, and the inner surface of the base body 1 is provided with a groove 102 that cooperates with the fastening mounts 501.

[0037] Specifically, after the prosthetic tooth 5 is installed onto the baseband body 1, it is engaged into the groove 102 via the top-mounted engaging platform 501, thus completing the assembly and installation of the prosthetic tooth 5. The engaging platform 501 is made of the same material as the prosthetic tooth 5, and its top is designed with a sloping guide structure to facilitate automatic sliding into the groove 102 during assembly, ensuring a one-time placement. The depth and width of the groove 102 are precisely calculated to form an interference fit with the engaging platform 501, effectively preventing the prosthetic tooth 5 from loosening or falling off under vibration or impact conditions. Furthermore, the staggered distribution of the engaging platform 501 and the positioning boss 6 optimizes load distribution, avoids stress concentration, and thus extends the overall service life of the prosthetic tooth 5. During maintenance, if the prosthetic tooth 5 needs to be disassembled, simply use a special tool to gently pry the engaging platform 501 to release the connection without damage; the operation is simple and does not affect other components.

[0038] refer to Figures 1-2 The conveying device for the base belt body 1 includes a special synchronous belt for false teeth. The conveying device also includes a frame 13 and multiple sets of conveying fixtures 7. Bearing seats 10 are installed at the four corners of the frame 13. Synchronous pulleys 11 are rotatably installed in the bearing seats 10. Two synchronous pulleys 11 located on the same side are connected to the base belt body 1, and the synchronous pulleys 11 are engaged with the tooth profile 2 of the base belt body 1. A drive shaft 12 is fixed between two opposite synchronous pulleys 11 by bolts. A motor seat 9 is fixed to one side of the frame 13 by bolts. A power motor 8 is provided on one side of the motor seat 9 to drive the drive shaft 12 to rotate around the axis of the drive shaft 12. The conveying fixtures 7 and the positioning boss 6 can be detachably installed.

[0039] The conveying fixture 7 and the positioning boss 6 in this utility model are installed by screw locking. The conveying fixture 7 has a recessed hole inside to avoid the screw end. The distance between two adjacent false teeth 5 is adapted to the width of the conveying fixture 7.

[0040] Specifically, the power motor 8 drives the transmission shaft 12 to rotate the synchronous pulley 11. The synchronous pulley 11 located on the same side is driven by the base belt body 1 and the tooth profile 2. The conveying fixture 7 assembled on the outer surface of the base belt body 1 is conveyed by the positioning boss 6 and the dummy tooth 5.

[0041] Furthermore, the power motor 8 is coaxially connected to the transmission shaft 12 via a coupling to ensure the stability of torque transmission. Adjustable support feet 14 are provided at the bottom of the frame 13 to correct the levelness of the conveying plane. The base belt body 1 is made of polyurethane composite material, possessing both wear resistance and tensile strength. The meshing clearance between its inner tooth profile 2 and the synchronous pulley 11 is controlled within ±0.1mm through precision machining. The bottom of the conveying fixture 7 is provided with a guide groove that matches the contour of the dummy tooth 5, ensuring no lateral deviation during conveying.

[0042] The dummy teeth 5, evenly distributed on the outer side of the baseband body 1, adopt a modular design. Each damaged dummy tooth 5 can be replaced independently. The spacing tolerance between adjacent dummy teeth 5 is controlled within ±0.3mm to ensure the positioning accuracy of the conveying fixture 7. During fixture installation, the operator must align the countersunk hole with the threaded hole of the positioning boss 6 and vertically tighten it using an internal hexagon countersunk screw, ensuring the screw head is completely submerged in the countersunk hole to avoid interference with the conveyed material.

[0043] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
