A limiting component for restricting the position of the glue cylinder is slidably arranged on the placing plate.

[0005] A squeezing component for squeezing the glue is slidably arranged at one end of the limiting component away from the clamping plates. The squeezing component cooperates with the glue cylinder.

[0006] Preferably, the squeezing component includes a first motor, a first gear, a second gear and a squeezing roller. The first motor is slidably arranged on the placing plate. The first gear is coaxially and fixedly arranged on the output shaft of the first motor. The second gear meshes with the first gear. The first gear and the second gear are both rotatably arranged on the placing table. Two squeezing rollers are provided. The two squeezing rollers are respectively coaxially and fixedly arranged at one ends of the first gear and the second gear away from the first motor. The two squeezing rollers are both in contact with the glue cylinder.

[0007] Preferably, a first mounting rod is slidably arranged on the placing plate. The first gear and the second gear are both rotatably connected to the first mounting rod. A second mounting rod is also slidably mounted on the placing plate. The first motor is fixedly mounted on the second mounting rod.

[0008] Preferably, the limiting component includes sliders symmetrically arranged on both sides of the glue cylinder, a second spring and a pressing block. The pressing block is fixedly arranged on the slider. The pressing block is fixedly connected to the slider through the second spring.

At one end of the workbench 1 away from the clamping plates 2, there is a slidably arranged placement plate 4. The position of the placement plate 4 can also be slid to change to cooperate with the dispensing position of the jewelry. On the placement plate 4, there is a slidably arranged limiting component for limiting the position of the glue cylinder 20.

[0020] At one end of the limiting component away from the clamping plates 2, there is a slidably arranged squeezing component for squeezing the glue. The squeezing component cooperates with the glue cylinder 20. The squeezing component includes a first motor 5, a first gear 6, a second gear 7, and a squeezing roller 8. The first motor 5 is slidably arranged on the placement plate 4. The first gear 6 is coaxially and fixedly arranged on the output shaft of the first motor 5. The second gear 7 meshes with the first gear 6. The first gear 6 and the second gear 7 are both rotatably arranged on the placement table. There are two squeezing rollers 8. The two squeezing rollers 8 are respectively coaxially and fixedly arranged at one end of the first gear 6 and the second gear 7 away from the first motor 5. The two squeezing rollers 8 are both in contact with the glue cylinder 20.

[0021] On the placement plate 4, there is a slidably arranged first mounting rod 9. The first gear 6 and the second gear 7 are both rotatably connected to the first mounting rod 9. On the placement plate 4, there is also a slidably mounted second mounting rod 10. The first motor 5 is fixedly mounted on the second mounting rod 10.

[0022] The limiting component includes sliders 11 symmetrically arranged on both sides of the glue cylinder 20, a second spring 12, and a pressing block 13.
