Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 4, the invention provides an automatic fine-tuning die head for normal-temperature coating, which comprises an upper die body 1, a lower die body 2 and a fine-tuning fixing device 3 for adjusting a die lip gap, wherein the fine-tuning fixing device 3 comprises a fine-tuning fixing seat 4, an expansion rod 5 and a protective cover 6, the fine-tuning fixing seat 4 is arranged along the width direction, the lower end of the fine-tuning fixing seat 4 is connected to the upper die body 1 through a screw, the expansion rod 5 is arranged on the fine-tuning fixing seat 4 along the width direction at equal intervals, the front end of the expansion rod 5 is abutted against the side wall of a die lip adjusting groove 7 of the upper die body 1, a heating rod 8 is arranged in the upper section of the expansion rod 5, the protective cover 6 is covered on the upper section of the fine-tuning fixing seat 4 and is positioned outside the heating rod 8, cooling air duct interfaces 9 are arranged at the left end and the right end of the protective cover 6, the adjustment of the die lip gap is, the front end of the expansion rod 5 is abutted against the side wall of the die lip adjusting groove 7. When the die lip clearance needs to be reduced, the temperature of the heating rod 8 is increased, so that the expansion rod 5 is heated to prolong the length, the front end of the expansion rod 5 extrudes the die lip adjusting groove 7, so that the die lip is deformed, and the die lip clearance is reduced; when the die lip clearance needs to be increased, the temperature of the heating rod 8 is reduced, so that the expansion rod 5 is cooled and shortened in length, the die lip adjusting groove 7 is restored to be deformed, the die lip clearance is increased, and the length of the expansion rod 5 is in corresponding relation with the temperature of the heating rod 8.
Preferably, the distance H between the lower end of the shield 6 and the upper die body 1 is larger than or equal to 50mm, and through multiple test selections, when the distance between the shield 6 and the upper die body 1 is set to be 50mm, most of heat can be blocked, and the heat generated by the heating rod 8 has little influence on the upper die body 1 and the lower die body 2.
Preferably, the fine adjustment fixing seat 4 is provided with a fluid cooling hole 10 penetrating through the left and right side walls in the width direction, a cooling medium in the fluid cooling hole 10 may be cold water, oil or gas, and the fine adjustment fixing seat 4 is timely cooled in a corresponding water cooling, oil cooling or air cooling manner.
Preferably, the upper die body 1 and the lower die body 2 are provided with fluid cooling circulation holes 11, and the upper die body 1 and the lower die body 2 can be cooled in time through the fluid cooling circulation holes 11 in a water cooling, air cooling or oil cooling mode.
The core point of the invention is that the length of the expansion rod 5 is controlled by controlling the temperature of the heating rod 8, so as to adjust the die lip gap, and simultaneously, the heat generated at the heating rod 8 is even taken away, thereby avoiding the influence of the heat on the normal work of the upper die body 1 and the lower die body 2, the heat is taken away in time by connecting cooling air at the heat insulation and cooling air pipe connector 9 of the shield 6, so as to achieve the heat insulation effect, in addition, the distance between the lower end of the shield 6 and the upper die body 1 is set to be H more than or equal to 50mm when in use, the heat generated at the heating rod 8 basically can not influence the upper die body 1 and the lower die body 2, so that the temperature of the upper die body 1 and the lower die body 2 can not be influenced by the heat at the fine adjustment fixing device 3.
