Embodiment 1

[0039] refer to Figure 1-5 , a casting die head automatic control system for polyester optical film, including a main machine system 1 and an auxiliary machine system 8, the main machine system 1 includes a main machine filter 2, a first main machine pipeline 3, a die head exhaust cover 4, and a die lip positioning Point 5, die head 12, die lip 13, cold drum 14, hot wire pipe 15, front die lip heater 16 and die head temperature assembly, auxiliary machine system 8 includes first auxiliary machine pipeline 6, auxiliary machine filter 7, Auxiliary machine system 8, numerical control system 9, dust cover 10, adapter 21, second auxiliary machine pipeline 22, the first main machine pipeline 3 and the first auxiliary machine pipeline 6 are connected through the die lip positioning point 5; the main machine system 1 is connected with the auxiliary machine system 8 through the first main machine pipeline 3, the first auxiliary machine pipeline 6, and the die lip positioning point 5; ...

Embodiment 2

[0048] refer to Figure 1-5 , in the present embodiment, the polyester cast sheet after drying enters die head 12 after entering static mixer again through extruder, pre-filter, metering pump, fine filter, and die head 12 automatically adjusts temperature, and die head is by high The precision die body and the die lip 13 are composed. The die head 12 is divided into four areas in the transverse direction (the first rear front area 17, the lower front area 18, the upper front area 19, and the second rear front area 20). Each area is independently Heating, the temperature of each zone can be independently adjusted and controlled, and the opening of the die lip 13 at each point can be automatically adjusted according to the actual thickness transmitted by the traction station system compared with the target thickness, and each heating unit is equipped with independent air cooling on both sides system to ensure accurate control of the thickness of the cast sheet. When the melt of ...

Abstract

The invention belongs to the technical field of polyester optical film production, particularly relates to a casting sheet mold head automatic control system for a polyester optical film, and aims to solve the problems that in the prior art, automatic dust removal cannot be implemented in a mold head casting sheet, the product quality of a film in the next process cannot be guaranteed, and the production efficiency is low. The system comprises a main machine system and an auxiliary machine system; the main machine system comprises a main machine filter, a first main machine pipeline, a mold head exhaust hood, a mold lip positioning point, a mold head, a mold lip, a cold drum, a hot wire pipe, a front mold lip heater and a mold head temperature assembly; the auxiliary machine system comprises a first auxiliary machine pipeline, an auxiliary machine filter, an auxiliary machine system, a numerical control system, a dust cover, an adapter and a second auxiliary machine pipeline; and the first main machine pipeline is connected with the first auxiliary machine pipeline. By utilizing the principle of electrostatic adsorption and humidification dust falling, dust particles can be automatically removed in the mold head casting piece, so that the product of the film in the next process is ensured to be free of defects, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of polyester optical film production, in particular to an automatic control system for casting dies for polyester optical films. Background technique [0002] In the production of polyester optical film, there are processes such as crystallization drying, melt extrusion, film casting, vertical and horizontal biaxial stretching, traction winding, slitting, recycling and granulation, and the general process flow in the melt extrusion process is: Dry chip 1> extruder 1> pre-filter 1> metering pump 1> fine filter 1> static mixer 1> die head, and the die head is the most critical equipment in the process, which is made of high-precision Die body and die lip, which can be divided into two parts for cleaning, polyester optical film manufacturing enterprises at home and abroad, there are still great defects in the dust removal of the die head, a lot of dust particles are produced in the cast sheet,...
