DETAILED DESCRIPTION

[0020] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0021] Embodiment: The utility model provides a ceramic roller drying device, see Figure 1-Figure 6As shown, it includes a box body 1, a box door 2, a heater 3, a connecting hose 30, a connecting hard pipe 31, a one-way ventilation valve 4, a discharge rack 5, an internal ventilation component and an external ventilation component. The box body 1 is hingedly connected to the box door 2 on the front side, and the box door 2 is connected and communicated with a one-way ventilation valve 4 on the lower right side. The one-way ventilation valve 4 is conducive to automatically adjusting the internal air pressure of the box body 1. When the air pressure value in the box body 1 is higher than the preset range, the gas inside the box body 1 can be discharged through the one-way ventilation valve 4, thereby achieving the purpose of pressure relief, so that the ceramic roller a is not affected during the drying process. A heater 3 is arranged on the rear side of the box body 1, and the upper and lower sides of the heater 3 are respectively connected to the connecting hose 30, and the ends of the connecting hose 30 are connected and communicated with the connecting hard pipe 31. A discharge rack 5 is arranged on the lower side of the box body 1, and internal ventilation components are distributed at intervals on the discharge rack 5. The internal ventilation components include positioning sleeves 6 and air permeable pipes 7, and positioning sleeves 6 and air permeable pipes 7 are arranged on the discharge rack 5 for vertically placing the ceramic roller a.

The upper inner side of the box body 1 is provided with an external ventilation component, which includes a cylinder 8, a connecting sleeve 9 and a nozzle 10, a cylinder 8 is arranged on the rear side of the top of the box body 1, the telescopic shaft of the cylinder 8 is connected to the upper connecting hard pipe 31, and the upper connecting hard pipe 31 is provided with connecting sleeves 9 at intervals, and the inner side of each connecting sleeve 9 is connected and communicated with a nozzle 10, and the nozzles 10 are respectively sleeved on the outer side of the ceramic roller a, and the hot air flow can be evenly sprayed onto the outer wall of the ceramic roller a through the nozzle 10 that can move back and forth up and down, which is beneficial to improve the drying efficiency of the outer wall of the ceramic roller a.

[0022] For further information, see Figure 2-Figure 6 As shown, air-permeable grooves 60 are spaced apart circumferentially on the upper portion of the positioning sleeve 6, which is beneficial to the smooth flow of air in the ceramic roller a, thereby facilitating the accelerated drying of the inner side of the ceramic roller a. The positioning sleeve 6 has a high outer ring and a low inner ring structure, which is beneficial to limiting the ceramic roller a.

[0023] For further information, see Figure 3-Figure 6 As shown, there is a gap between the outer wall of the air permeable tube 7 and the inner wall of the ceramic roller a, and there is also a gap between the inner wall of the nozzle 10 and the outer wall of the ceramic roller a, which is conducive to the smooth flow of hot air and is more conducive to accelerating the drying efficiency of the ceramic roller a.

[0024] In addition, see Figure 1-Figure 3As shown, a temperature sensor 11 and a control panel 12 are also included.

The control panel 12 is arranged on the upper right side of the outer wall of the box body 1, and the heater 3 and the temperature sensor 11 are electrically connected to the control panel 12. By adjusting the parameters on the control panel 12, the heating temperature of the heater 3 can be adjusted accordingly, so that the ceramic roller a can always be kept at a suitable temperature during the drying process, avoiding the influence of high temperature on the quality of the ceramic roller a.

[0025] Open the box door 2, and put the ceramic rollers a to be dried on the corresponding positioning sleeves 6 respectively. After the ceramic rollers a are placed, close the box door 2, and then start the heater 3, so that the hot air can pass through the connecting hose 30 and the connecting hard pipe 31 to the air pipe 7 and the nozzle 10 respectively, and then the hot air flow can be evenly sprayed to the inner wall of the ceramic roller a through the air pipe 7, and the cylinder 8 is started to control the telescopic rod thereon to reciprocately extend and shorten, so that the connecting sleeve 9 and the nozzle 10 can be driven to move up and down synchronously, and then the hot air can be evenly sprayed to the outer wall of the ceramic roller a through the nozzle 10. In this way, through the cooperation of the air pipe 7 and the nozzle 10, the inner and outer walls of the ceramic roller a can be evenly sprayed with hot air, so that the inner and outer sides of the ceramic roller a can be heated evenly, which is beneficial to improve the efficiency of drying the ceramic roller a.
