[0027] See also Figure 1-5, a metal jewelry tablet press, comprising an operating table 1, on which an upper pressing roller 11, a lower pressing roller 12 and a moving component for adjusting the spacing between the upper and lower pressing rollers 12 are provided, the operating table 1 is also provided with a first motor, the output end of the first motor is fixedly connected to the roller shaft of the upper pressing roller 11, and also includes a width adjustment mechanism, the width adjustment mechanism is respectively connected to two connecting blocks 2, each connecting block 2 is connected to the adjusting component through a connecting component; the adjusting component comprises a fixed block 3 connected to the connecting component and an adjusting plate 31 fixedly connected to the fixed block 3, the adjusting plate 31 is provided with a telescopic component that can abut against the upper pressing roller 11 and the lower pressing roller 12; the telescopic component comprises a first inclined plate 32 and a second inclined plate 33 respectively slidably connected to the adjusting plate 31, the first inclined plate 32 abuts against the lower pressing roller 12, and the inclined surfaces of the first inclined plate 32 and the second inclined plate 33 abut against each other, and under the push of the first inclined plate 32, the second inclined plate 33 slides along the adjusting plate 31 and abuts against the upper pressing roller 11.

[0028] The moving assembly can use a screw 5, an electric push rod, a hydraulic cylinder, etc. as a driving source, and drive the upper pressing roller 11 to perform linear motion to adjust the distance between the upper pressing roller 11 and the lower pressing roller 12. This is the prior art and will not be described in detail.

[0029] By setting a telescopic assembly, the first inclined plate 32 can be moved to push the second inclined plate 33 to move, and the second inclined plate 33 can be brought into contact with the upper pressing roller 11. At this time, the first inclined plate 32 and the second inclined plate 33 together form an inclined surface for pressing the chamfer of the metal strip, that is, through the telescopic assembly, the chamfer pressing of the metal strip can be completed in a tablet press with adjustable tablet thickness. Through the connecting assembly, the connecting block 2 for adjusting the width is connected to the adjusting assembly for controlling the inclination degree of the chamfer of the metal strip. By replacing the adjusting assembly with different inclination angles, metal strips with different chamfers can be prepared, which enriches the function of the tablet press, improves the processing efficiency of metal jewelry, and enhances the applicability of the tablet press.

[0030] Furthermore, the adjustment plate 31 is provided with a first sliding groove 34 and a second sliding groove 35, respectively, and the direction of the second sliding groove 35 is parallel to the tilting direction of the adjustment plate 31, the first inclined plate 32 is fixedly provided with a first slider 36 slidably connected to the first sliding groove 34, the second inclined plate 33 is fixedly provided with a second slider 37 slidably connected to the second sliding groove 35, and the first slider 36 and the second slider 37 are both arranged in a T shape. The T shape can prevent the first slider 36 and the second slider 37 from being separated from the first sliding groove 34 and the second sliding groove 35 when sliding.

[0031] The first inclined plate 32 is pushed, and the first inclined plate 32 moves along the adjustment plate 31 through the cooperation of the first slider 36 and the first sliding groove 34, and the abutting second inclined plate 33 is pushed to move, and the second inclined plate 33 moves to abut against the upper pressing roller 11 through the cooperation of the second slider 37 and the second sliding groove 35 and under the constraint of the second sliding groove 35, so that the tablet press can prepare metal strips with chamfers.

[0032] Furthermore, the adjustment plate 31 includes a vertical plate and a plurality of inclined plates with different inclination angles. By prefabricating adjustment plates 31 with different angles, metal strips with different chamfers can be prepared. It should be noted that the adjustment plate 31 is fixedly connected to the fixing block 3, and different adjustment plates 31 are connected to corresponding fixing blocks 3 to form a complete adjustment assembly.

[0033] Furthermore, a locking mechanism is included, which includes a pin 41. A plurality of pin holes 4 are provided on the adjusting plate 31. The pin 41 is inserted into the pin hole 4. The first inclined plate 32 is locked by the engagement between the pin 41 and the pin hole 4.

[0034] Furthermore, the connection assembly includes two right-angle plates 21 fixedly arranged in the connection groove on the connection block 2, and the two right-angle plates 21 and the connection block 2 together form a mounting channel 22, and a mounting plate 38 adapted to the mounting channel 22 is fixedly arranged on one surface of the fixed block 3 close to the connection block 2. The opening direction of the mounting channel 22 is opposite to the rotation direction of the upper pressure roller 11, so as to avoid the force exerted by the metal strip on the adjustment plate 31, causing the mounting plate 38 to slip out of the mounting groove.

[0035] The mounting plate 38 is inserted into the mounting channel 22, so that the fixed block 3 and the adjustment plate 31 are installed on the connecting block 2, and the fixed block 3 can move with the connecting block 2 to obtain metal strips of different widths; and this detachable design can quickly replace the adjustment plates 31 with different inclination angles to make metal strips with different chamfers, which greatly facilitates personnel operation.

[0036] Further, the width adjustment mechanism includes a screw rod 5 rotatably arranged on the operating table 1, the screw rod 5 is a bidirectional screw rod 5, one end of the screw rod 5 is fixedly connected to the output end of the second motor, the second motor is fixedly connected to the operating table 1, the connection block 2 is respectively threadedly connected to both sides of the screw rod 5, and the rotation of the screw rod 5 drives the connection block 2 to move toward or away from each other. The rotation of the second motor drives the screw rod 5 to rotate, and the rotation of the screw rod 5 drives the connection block 2 to move toward or away from each other.

[0037] Furthermore, the width adjustment mechanism further includes a slide bar fixedly connected to the operating table 1, and each of the connecting blocks 2 is slidably connected to the slide bar. When the screw 5 rotates, the connecting block 2 is constrained from rotating by the upper pressing roller 11 and the lower pressing roller 12, resulting in serious wear on the contact surface between the connecting block 2 and the upper pressing roller 11 and the lower pressing roller 12, so the slide bar is added as a rotation constraint on the connecting block 2.

[0038] Working principle:

[0039] When adjusting the width, the second motor rotates to drive the screw rod 5 to rotate, and the screw rod 5 rotates to drive the connecting block 2 to move toward or away from each other. The mounting plate 38 is inserted into the mounting channel 22, so that the fixing block 3 and the adjusting plate 31 are installed on the connecting block 2, and the fixing block 3 can move with the connecting block 2 to obtain metal strips of different widths.

[0040] When adjusting the chamfer, push the first inclined plate 32, and through the cooperation of the first slider 36 and the first sliding groove 34, the first inclined plate 32 moves along the adjustment plate 31, and pushes the abutting second inclined plate 33 to move, through the cooperation of the second slider 37 and the second sliding groove 35, and under the constraint of the second sliding groove 35, the second inclined plate 33 moves to abut against the upper pressing roller 11, so that the tablet press can prepare metal strips with chamfers. After the adjustment is completed, the pin 41 is inserted into the pin hole 4 to lock the first inclined plate 32.

[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
