Description

Technical Field

[0001] The utility model relates to the technical field of extrusion tablet presses, in particular to a powder coating melt extrusion tablet press. Background Art

[0002] At present, the powder coating processing technology disclosed in the prior art includes raw material mixing, extrusion by an extruder, pressing the extrudate into thin sheets by a tablet press, sending the thin sheets to a crushing roller device by a conveyor belt to be crushed into fragments, and grinding the fragments by a grinder to finally meet the production conditions of the powder coating. However, in the actual processing process, after long-term use, the temperature of the roller structure of the extruder itself rises, the temperature of the extruded thin sheets is relatively high, and when the hardness is insufficient and they are transported to the crushing roller device for crushing, poor cutting is likely to occur, causing the overall material to shake and deviate.

[0003] In recent years, with the further development of relevant technologies, researchers in related fields have also disclosed some solutions to the problems existing in the above-mentioned existing technologies. For example, the patent document with application number 202320855520.5 discloses that "by installing multiple groups of cooling boxes with cold air blowers on the conveyor belt at the same time, the raw materials after tableting can be quickly cooled, which is conducive to their rapid molding and subsequent crushing operations." However, although air blowing cooling can ensure rapid cooling of the sheet material, a large amount of hot air generated by the cooling will also spread to the processing environment, and the comfort of operation will be greatly reduced. Moreover, as the use time increases, the temperature of the overall processing environment will gradually rise, which will lead to a gradual decline in the air blowing cooling effect.

[0029] Working principle: Embodiment 1:

[0030] During the processing, the sheet material 3 output by the tablet press 4 will be actively conveyed by the conveyor belt device 2, and the top surface of the sheet material 3 passes through the gap space between the bottom of the heat conduction cylinder fitting 10 and the top of the conveyor belt device 2. The heat conduction cylinder fitting 10 will rotate synchronously under the support of the heat absorption pipe fitting 9 and the extension support plate 8 to reduce the frictional resistance to the sheet material 3. Then, the sheet material 3 is reciprocally conveyed into the internal of the pair-roll crushing device 5 for crushing processing to meet the processing requirements of the powder coating;

[0031] When the sheet material 3 is hard due to high temperature before entering the pair-roll crushing device 5, the water pump 12 can be started. The water pump 12 conveys the coolant in the coolant tank 11 to the inside of the heat absorption pipe fitting 9 through the reflux pipe 13. At the same time, the heat conduction cylinder 101 and the multiple radiating fins 102 sleeved inside the heat conduction cylinder 101 synchronously conduct the heat of the sheet material 3 to the hose 91 during the process of contacting and rotating with the sheet material 3, and the coolant flowing through the hose 91 absorbs it. Furthermore, heat conduction cooling of the sheet material 3 is realized. The used coolant will enter the inside of the coolant tank 11 through the infusion pipe 14. Thus, reciprocally, synchronous cooling treatment is carried out on the continuously processed sheet material 3. The cooled sheet material 3 is continuously conveyed by the conveyor belt device 2 and enters the inside of the pair-roll crushing device 5, and continues to be crushed and processed;

[0032] When the coolant in the coolant tank 11 reaches the same temperature, the coolant in the coolant tank 11 can be replaced through the liquid filling valve pipe and the liquid discharge valve pipe. Embodiment 2:

[0033] The crushing and cooling of the sheet material 3 can be carried out according to the steps of the above-mentioned embodiment. When it is necessary to adjust the use height of the heat conduction cylinder member 10, the two electromagnets 15 that are originally in the on state can be turned off, and then the support shaft 7, the extension support plate 8, the heat absorption pipe member 9, and the heat conduction cylinder member 10 are flipped until the heat conduction cylinder member 10 is at an appropriate height. Then, the two electromagnets 15 are restarted, and the two electromagnets 15 magnetically attract and limit the two support shafts 7 again, and that's it.
