The bottom of the connecting frame 9 is threadedly connected to the second fixing bolt 10. The top of the second fixing bolt 10 longitudinally passes through the clamping frame 11 and is threadedly connected to the connecting frame 9. The clamping frame 11 is sleeved on the transverse end surface of the connecting frame 9. The top of the clamping frame 11 longitudinally passes through and is threadedly connected to the pressure rod 12. In this design, the tablet press body 1 constitutes the main body of the gold tablet press, and a large number of components related to the gold tablet press are set therein. Since they are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0022] The main model of the gold processing tablet press in this solution is: speed-regulating electric European-style tablet press.

[0023] In use: The main body of the gold processing tablet press is powered by a motor assembly. The speed is reduced to a suitable pressing speed by a reducer and then transmitted to the drive shaft, which ultimately drives the mold and punch to perform the pressing operation. During the pressing process, the gold raw material is fed by rotating against one side of the transmission assembly of the tablet press, and at the same time, the tableting rollers squeeze each other to process the gold raw material into tablets.

[0024] Preferably, the mounting frame 3, motor 4, lead screw 5 and moving frame 6 form a threaded connection structure, and bearings are provided on the inner wall of the longitudinal end of the mounting frame 3.

[0025] In actual use, the starter motor 4 drives the connected lead screw 5 to rotate on the bearing on the inner wall of the mounting bracket 3, thereby driving the connected movable bracket 6 to move threadedly on the lead screw 5.

[0026] Preferably, the extension frame 2, the lead screw 5, the movable frame 6 and the slide assembly 7 form a sliding connection structure. Two rectangular through slots are longitudinally opened on the side wall of the extension frame 2, and the shape and size of the through slots are adapted to the longitudinal end of the movable frame 6.

[0027] In actual use, when the movable frame 6 moves, its other side slides on the slide assembly 7, thereby making the movable frame 6 slide stably on the side wall of the extension frame 2.

[0028] Preferably, the movable frame 6, the first fixing bolt 8 and the connecting frame 9 form a threaded connection structure. The connecting frame 9 is an inverted "U" shaped integral structure, and a rectangular groove is opened at the bottom of the longitudinal end of the connecting frame 9. The shape and size of the groove are adapted to the top of the longitudinal end of the movable frame 6.

[0029] In actual use, the movable frame 6 slides stably on the side wall of the extension frame 2, thereby driving the connecting frame 9, which is fixed to the movable frame 6 by the first fixing bolt 8, to move together.

[0030] Preferably, the connecting frame 9, the second fixing bolt 10 and the clamping frame 11 form a threaded connection structure. Two rows of threaded grooves are equally spaced at the bottom of the horizontal plate of the connecting frame 9, and the shape and size of the threaded grooves are adapted to the second fixing bolt 10.

[0031] In practical use, the second fixing bolt 10 passes through the threaded groove at the corresponding position at the bottom of the connecting frame 9 and is fixed to the clamping frame 11, thereby facilitating the fixing of the clamping frames 11 on both sides against the gold raw material.

[0032] Preferably, the clamping frame 11 has a "C" shaped integrated structure, the top horizontal plate of the clamping frame 11 has a circular threaded through groove, and the shape and size of the through groove are adapted to the longitudinal end of the pressure rod 12, and the bottom disc surface of the pressure rod 12 is provided with rubber protrusions.

[0033] In actual use, the pressure rods 12 at both ends are rotated downwards, so that the rubber protrusions at the bottom of the pressure rods 12 abut against the top of the gold material, thereby fixing the position of the gold material on the connecting frame 9 and the clamping frame 11.

[0034] Working principle: During gold jewelry processing, the two ends of the gold material to be pressed are respectively abutted against the open ends of the clamping frame 11. Then, the positions of the clamping frames 11 on the connecting frame 9 are adjusted according to the size of the gold material. The second fixing bolt 10 passes through the corresponding threaded groove at the bottom of the connecting frame 9 and is fixed to the clamping frame 11, thus facilitating the fixing of the two clamping frames 11 against the two sides of the gold material. Then, the pressure rods 12 at both ends are rotated downwards, so that the rubber protrusions at the bottom of the pressure rods 12 abut against the top of the gold material, thereby fixing the position of the gold material on the connecting frame 9 and the clamping frame 11. After that, the motor is started. 4 drives the connected lead screw 5 to rotate on the bearing on the inner wall of the mounting frame 3, thereby driving the connected movable frame 6 to move threadedly on the lead screw 5. When the movable frame 6 moves, its other side slides on the slide assembly 7, thereby making the movable frame 6 slide stably on the side wall of the extension frame 2, and then driving the connecting frame 9, which is fixed on the movable frame 6 by the first fixing bolt 8, to move together, so that the gold raw material fixed on the clamping frame 11 is automatically fed to the end of the tablet press body 1. At the same time, during processing, the clamping frame 11 of appropriate height is selected according to the height of the tablet pressing roller of the tablet press body 1 and fixed on the connecting frame 9, so as to facilitate accurate docking of the gold raw material and the tablet pressing inlet of the tablet press body 1.
