The concrete arrangement of the glaze spraying assembly can be seen in reference to fig. 4-6. In the enlarged detail shown in fig. 5, the arrangement of the fixing pins 10 on the transport belt 20 relative to the protective cover 51 can be clearly seen. In the perspective view of fig. 6, the mounting position of the driving gear 31 relative to the fixed pin 10 at the spray gun 40 and the power motor 30 can be seen. With the structure, when the fixed contact pin 10 is positioned and conveyed to the glaze spraying position by the chain link structure of the conveyor belt 20, the spray gun 40 is started and glaze slurry spraying is carried out as shown in fig. 6; the power motor 30 synchronously drives the fixed contact pin 10 and the ceramic cigarette holder on the fixed contact pin 10 to rotate through the driving gear 31, and accordingly, the online glaze slurry spraying operation of the ceramic cigarette holder is realized.

Considering the harmfulness of dust generated by glaze spraying of the spray gun 40 to the periphery and even workers, the utility model is additionally provided with a protective cover 51 as shown in figures 1-4, and utilizes the negative pressure generated by a fan 53 to absorb the glaze slurry dust generated at the glaze spraying position in the cover cavity of the protective cover 51 on line; the glaze slurry dust is sucked away and then enters external dust collecting equipment for subsequent harmless and environment-friendly treatment.

Fourth, drying assembly

The drying assembly includes a drying drum 61 having a high temperature chamber and a heating element disposed in the drum cavity of the drying drum 61 for generating a high temperature environment. The drying cylinder 61 can have various structures, and only a drying chamber can be formed by itself. The heating element is used for forming a high-temperature environment in the cylinder cavity of the drying cylinder 61, and after the ceramic cigarette holder inserted in the fixed contact pin 10 is sprayed with glaze, the ceramic cigarette holder can enter the cylinder cavity of the drying cylinder 61 through the feeding end of the drying cylinder 61 and is continuously dried while being continuously conveyed to move forwards by the conveying belt 20. When the ceramic cigarette holder inserted in the fixed contact pin 10 is moved out from the discharge end of the drying cylinder 61, the ceramic cigarette holder is dried, and then the ceramic cigarette holder enters the blanking area and waits for blanking operation.

For the communicating pipe 62, the circulating fan is used as a power source, so that the purpose of circulating reciprocating closed circulation of hot air from the discharge end to the feed end in the drying cylinder 61 is achieved, the drying efficiency is improved, and the using effect is excellent. When necessary, even the drying process can be considered, a great amount of harmful gas is inevitably accompanied with the drying progress, so that the air outlet pipe can be directly arranged on the drying cylinder 61 to communicate the cover cavity of the protective cover 51 with the cylinder cavity of the drying cylinder 61. In actual use, an opening may be left at the nozzle of the drying drum 61, and the opening communicates with the cover cavity of the protective cover 51. The opening design or the air outlet design aims to realize the function of absorbing glaze spraying dust and even drying gas together by utilizing the negative pressure of the fan 53 to the air pipe 52. The sucked harmful gas and dust can be subjected to subsequent shunting operation, so that the aim of targeted harmless emission is fulfilled.

Of course, the above-described arrangements are merely illustrative of the structures in the specific embodiments shown in FIGS. 1-7; in actual operation, if a belt conveyor or a plate chain conveyor is adopted to replace the conveying chain, or the conveying belt 20 adopts a linear conveying belt instead of a closed-loop conveying belt, or even the drying component is provided with a smoke dust treatment device, these changes are in the conventional changes of the original structure and function of the utility model, which should be regarded as equivalent or similar designs, and fall into the protection scope of the utility model.
