Problems solved by technology

This kind of manual adjustment often takes several hours, and it is very difficult to read the labels on the densely distributed adjusting bolt heads. The lighting of the production environment is poor, and the lighting light on the top of the factory building is blocked by the rack, causing operators to Unable to clearly identify the position of the adjusting bolt, on the one hand, it affects the production progress and increases the labor intensity of the staff; on the other hand, it also increases the possibility of misoperation, wastes raw materials, and prolongs the debugging time

Embodiment 1

[0020] Embodiment one: if figure 1 , 2 As shown, it is a lighting device on an EVA film extruder according to the present invention, including a bulb 1, a connecting rod and a base 3, the bulb 1 is a high-power energy-saving bulb 1, and the bottom of the base 3 is fixed on a hoisting On the frame 4 of the die head, one end of the connecting rod is rotatably connected to the base 3, and the other end is connected to the bulb 1 through the lamp holder 5, and the electric wire 8 in the lamp holder 5 passes through the connecting rod The inner cavity and the base 3 are connected to the power supply on the extruder, and a PVC protective tube (not shown) is set on the drawn electric wire 8 to ensure the safety of the electric wire 8.

[0021] The connecting rod is composed of a straight rod part 2 and a curved rod part 6, the straight rod part 2 is connected to the base 3 in rotation, the curved rod part 6 is connected to the lamp holder 5, and the curved rod part 6 consists of a ...

Embodiment 2

[0022] Embodiment 2: A lighting device on an EVA film extruder. In this embodiment, its structure is similar to that of Embodiment 1. The difference is that the straight rod part is composed of inner and outer telescopic sleeves. The outer telescopic sleeve is provided with a positioning hole, and the inner telescopic sleeve is provided with a protrusion matching the positioning hole. The straight rod part is retractable, which is more convenient for the operator to adjust the light. When it is not in use, it can be stowed to reduce the interference of the lighting device on other operating procedures in the production of EVA film.

Abstract

The invention discloses an illumination device of an ethylene-vinyl acetate (EVA) film extruder. The illumination device is characterized in that the illumination device comprises a lamp bulb, a connection rod and a base; the bottom of the base is fixed to a frame for hoisting of a die head; one end of the connection rod is rotatingly connected to the base and the other end is connected to the lamp bulb by a lamp socket; and an electric wire in the lamp socket passes through a cavity of the connection rod, and the base, and is electrically connected to a power supply of an EVA film extruder. The illumination device is arranged on the frame above the die head, provides good illumination rays for adjustment of bolt tightness in EVA film thickness adjustment, reduces misoperation, and effectively improves work efficiency.

Description

technical field [0001] The invention relates to an EVA film production equipment, in particular to a lighting device on an EVA film extruder. Background technique [0002] If the solar cell is directly exposed to the air, its photoelectric conversion efficiency will drop quickly and lose its practical value. Therefore, research and development of packaging materials for solar cells is very important. In order to achieve the purpose of isolation from the outside world, the solar cells are encapsulated with an ethylene-vinyl acetate copolymer (EVA) film that is transparent, resistant to light aging, has good adhesive properties, can withstand atmospheric changes, and is connected with the upper and lower layers. The protective materials are bonded together to make up the solar cell module. [0003] EVA is a typical random polymer compound. In its molecular structure, the arrangement of substituents on the molecular chain is irregular, and the configuration of asymmetric carb...
