Problems solved by technology

When the nylon film is just extruded, due to the high temperature, the mineral oil in the nylon will volatilize and form oily smoke, which will stick to the T-die. Drops, pollute the touch head of the T-die, and it is easy to drip and pollute the product
Therefore, in the existing nylon film extrusion molding process, it is necessary to stop regularly to clean up the oil droplets stuck on the T-die, which reduces the production efficiency

Embodiment Construction

[0017] The present invention is further elaborated below by specific embodiment:

[0018] figure 1 An extruder is shown, including a T-die 100 , an air inlet device 200 , a fixing bracket 300 , a blow pipe 400 and a fume hood 500 .

[0019] combine figure 1 and figure 2 , the T-die 100 is elongated, the upper half of its two sides is a vertical plane, the lower half is a slope 101 extending obliquely towards the middle of the bottom, and the middle of the bottom has a die opening 102 for discharging .

[0020] combine figure 1 and image 3 There are two oil fume hoods 500, which are arranged close to the upper half of the two sides of the T-die 100 respectively. The oil fume hoods 500 are connected with exhaust fans and can be used to absorb the oil fume 104 produced in the extrusion process.

[0021] combine figure 1 and figure 2 , a total of two blowing pipes 400 are located on the slopes 101 on both sides of the T-die 100, and the blowing pipes 400 are fixed by th...

Abstract

The invention provides a T-mold oil fume removal method of an extruder. The extruder comprises a T mold, a blowpipe and air inlet devices, inclined planes extending towards the middle of the bottom surface along the inclined direction are arranged on two sides of the T mold, a mold opening for discharging is formed in the middle of the bottom surface of the T mold, the blowpipe is arranged at theinclined planes, the air inlet devices are connected with the blowpipe, and an air outlet facing the inclined planes is formed in the blowpipe. The method comprises the following steps that the air inlet devices are opened, air is discharged from the air outlet of the blowpipe, and an air curtain covering the inclined planes of the T mold is formed; and a nylon film is extruded from a mold openingof the T mold, oil fume generated during extrusion of the nylon film is blocked by the air curtain to keep away from the inclined planes of the T mold. Therefore, the problem that the oil fume adhered to the T mold pollutes a mold head and a product is solved.

Description

technical field [0001] The invention relates to the field of nylon manufacturing equipment, in particular to a method for removing oil fume from a T-die of an extruder. Background technique [0002] In the extrusion molding process of the nylon film, the nylon material is heated and softened in the T-die, and then extruded from the die head of the T-die to form a nylon film. When the nylon film is just extruded, due to the high temperature, the mineral oil in the nylon will volatilize and form oily smoke, which will stick to the T-die. Dropping, polluting the touch head of the T-die, it is also easy to drip and pollute the product. Therefore, in the existing nylon film extrusion molding process, it is necessary to stop regularly to clean up the oil droplets stuck on the T die, which reduces the production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for removing oily fumes from the T-die...
