Embodiment 1

[0030] Cooperate image 3 and Figure 4 As shown, 35% LDPE 100AC, 55% LLDPE 7050 and 10% functional masterbatch are used as raw materials. During production, it is extruded by a single-screw extruder to form a cast film 1 . Entering the vacuum punching device, in the vacuum suction area 5 of the vacuum forming drum 8, due to the effect of the internal and external pressure difference, a perforated film 2 with small holes 9 is formed. The temperature of the cast film reaches 110°C, and the temperature of the cast film can be controlled to reach the required temperature by controlling the temperature of the extrusion die, and the vacuum can be adjusted to 0.05 MPa by adjusting the speed of the vacuum pump. And the ultrasonic atomization device 6 that is positioned at the vacuum forming drum 8 vacuum suction area 5 directly opposite, the moisture of atomization makes the humidity of the air sucked by the vacuum suction area 5 reach 70%, thus when the moisture in the air adheres ...

Embodiment 2

[0040] Cooperate Figure 5 and Figure 6 As shown, 25% LDPE 100AC, 65% LLDPE 9500 and 10% functional masterbatch are used as raw materials. During production, it is extruded through a single-screw extruder to form a cast film 1 . The cast film 1 enters the vacuum punching equipment at high temperature for vacuum punching to form a perforated film 2 with small holes 9. At this time, the temperature of the cast film when the vacuum punching is detected by the infrared thermal imager FLUKE Ti110-9HZ reaches 115°C, the casting film can reach the required temperature by controlling the temperature of the extrusion die, and the vacuum degree can reach 0.08MPa by adjusting the speed of the vacuum pump. The ultrasonic atomization device 6 located directly opposite to the vacuum suction area 5 of the vacuum forming drum 8 makes the atomized moisture adhere to the high-temperature perforated film 2 after the film is perforated, and will be taken away due to the evaporative cooling effe...

Embodiment 3

[0042] Cooperate Figure 7 and Figure 8 As shown, 20% LDPE 100AC, 65% LLDPE 9500 and 15% functional masterbatch are used as raw materials. During production, it is extruded through a single-screw extruder to form a cast film 1 . The cast film 1 enters the vacuum punching equipment at high temperature for vacuum punching to form a perforated film 2 with small holes 9. At this time, the temperature of the cast film when the vacuum punching is detected by the infrared thermal imager FLUKE Ti110-9HZ reaches 112°C, the casting film can reach the required temperature by controlling the temperature of the extrusion die, and the vacuum can reach 0.05MPa by adjusting the speed of the vacuum pump. The ultrasonic atomization device 6 located directly opposite the vacuum suction area 5 of the vacuum forming drum 8 makes the atomized moisture adhere to the high-temperature perforated film 2 after the film is perforated, and will be taken away due to evaporative cooling With a large amou...

Abstract

The invention discloses a production method for a perforating thin film and a vacuum perforating device of the production method. The production method comprises the specific production steps that a cast film enters the vacuum perforating device, in a vacuum suction mouth area of a forming drum, due to the effect of inside-outside pressure difference, the perforating thin film of a funnel-shaped small hole structure is formed, and the hole shape of the perforating thin film is identical to that of a forming mesh cage on the outside of the forming drum; meanwhile, an ultrasonic atomization device located on the opposite face of the vacuum suction mouth area of the forming drum conducts surface spray cooling on the perforating thin film with small holes, and thus the surface temperature of the perforating thin film is lowered to 50 DEG C-room temperature; and according to the production method, the shape of the vacuum-perforated perforating thin film of the small hole structure can be set fast, flattening deformation does not occur to the perforating thin film when the perforating thin film enters a tension control procedure and a mechanical perforating procedure, and thus fast and synchronous production of small hole vacuum perforating production and large hole mechanical perforating production is achieved. Therefore, the functions of energy saving, cost reduction, improving of production efficiency and prevention of material secondary pollution are achieved.

Description

technical field [0001] The invention relates to a production method of a perforated film, in particular to a vacuum perforating device and a production method of a perforated film with a structure of small holes and large pores. Background technique [0002] Apertured films are widely used in the surface layer of sanitary napkins and sanitary pads, which is commonly referred to as dry mesh. However, the perforated film has the disadvantages of plastic feeling, poor flexibility, and slow absorption speed. In order to improve these shortcomings, CN200620057798.4 mentions a small-hole tactile film structure. The capillary that extends from the surface, the capillary forms a raised film angle on the second face of the film: at the same time on the second face of the film to the first face to form a micropore with a larger opening area, the second face of the film is on the second face of the film When the film is applied, it is used as the face in contact with human skin. It i...
