Abstract
A device for preparing micropores on a plastic film consists of a pair of parallel rollers having the same diameter and length. Each roller is made of stainless steel materials, and is provided with a shaft on the axis and bearings on two ends of the shaft, so that the roller can rotate. The distance and pressure between the two rollers are adjustable. One roller at one end of which a gear connected with a motor is arranged is a driving roller and drives the other roller to relatively rotate by the pressure between the two rollers. Inorganic solid particles, which can be one or the mixture of more of alumina, carborundum, artificial diamond and the like, and have sharp points of 100-300 meshes are fixed on the surface of one roller by an electrodeposition process. Stainless steel, an alumina coating, a rubber sleeve or a nylon sleeve can be fixed on the surface of the other roller. The plastic film passes through the two rollers, and the hard particles act on the plastic film by regulating the pressure between the two rollers and form a large number of uniformly-distributed micropores on the plastic film.

It is the fixing inorganic solid particles of electro-deposition method that there is the surface of the round roller of hard and sharp inorganic solid particles on one of them surface, its particle can be a kind of in aluminium oxide, carborundum, the diamond or mix several; Have sharp tip on each particle, size is between the 100-300 order.
Another circle roller surface is smooth surface stainless steel; Another circle roller surface or smooth aluminum oxide coating layer face; Another is justified roller surface or smooth nylon jacket is arranged; Another is justified roller surface or the smooth rubber cover is arranged.
Characteristics of the present invention:
This apparatus structure is simple, and is easy to use, the preservative film ventilation performance height of production, and keep higher transparency.Device can be assembled on the blow moulded polyethyene equipment, and the blowing of polyethylene preservative film, pore are carried out simultaneously.
Description of drawings
Fig. 1 is the device front view of preparation micropore on preservative film.
The specific embodiment
As a kind of device that on preservative film, prepares micropore of Fig. 1, a pair of round roller (1,2) that is arranged in parallel is arranged on the device, the diameter of circle roller is consistent with length, and there is hard and sharp inorganic solid particles 3 on the surface of one of them circle roller 1; Bearing on the axle at two round roller two ends is contained on the bearing block, bearing block on two round roller two end axles is contained in respectively on two bearing block slideways 4 of two round roller both sides, bearing block 5 on round roller 1 two end axles is fixed on the bearing block slideway, bearing block 6 activities at the two ends on another circle roller 2 two end axles are contained on the bearing block slideway, mobilizable bearing block flexibly connects regulates leading screw 7, it is parallel with the bearing block slideway to regulate leading screw, the upper end of regulating leading screw passes the fixing threaded hole 8 on bearing block slideway top, passes to be equipped with on the top of adjusting leading screw of bearing block slideway top fixing threaded hole to adjust wheel 9; Stationary roll also is referred to as drive roll 1, on the axle of drive roll one end the gear 11 that links to each other with motor 10 is housed, and on the axle of stationary roll and movable roll sprocket wheel is housed all, between sprocket wheel 12 on the stationary roll and the sprocket wheel 13 on the movable roll chain 14 is arranged.
It is the fixing inorganic solid particles of electro-deposition method that there is the surface of the round roller of hard and sharp inorganic solid particles on one of them surface, its particle can be a kind of in aluminium oxide, carborundum, the diamond or mix several; Have sharp tip on each particle, size is between the 100-300 order.
Another circle roller surface is smooth surface stainless steel, or smooth aluminum oxide coating layer face, or smooth nylon jacket is arranged.Or the smooth rubber cover arranged.
This a kind of device that on preservative film, prepares micropore, device is made up of a pair of round roller that is arranged in parallel, and the diameter of circle roller is consistent with length, and there is hard and sharp inorganic solid particles on the surface of one of them circle roller.Bright film passes between two rollers, and by regulating the pressure between two rollers, hard particles acts on preservative film, and produces a large amount of equally distributed small pores on preservative film.The circle roller is made by stainless steel material, on the axis of circle roller axle is arranged, and bearing is installed at two of axle, and round roller can be rotated.Distance and pressure between the two circle rollers can be regulated.One end of a roller is installed the gear that links to each other with motor, is drive roll, relies on pressure between two rollers to drive another roller and does and relatively rotate.Preservative film passes between two rollers, does when relatively rotating when two rollers, and preservative film moves thereupon.The method fixed inorganic solid particle of electro-deposition is adopted on the surface of one of them circle roller.Particle can be a kind of in aluminium oxide, carborundum, the diamond etc. or mix several.Particle has sharp tip, and size is between the 100-300 order.Another circle roller surface can be a stainless steel, or is aluminum oxide coating layer, or is nylon jacket, or is rubber sleeve.Because of the material difference, this roller case hardness difference.The oxygen of the preservative film of being produced and carbon dioxide infiltration coefficient are 1～40 * 10
5(mL/m
2Datm) between.
During use, device can be directly installed on the rear of blow moulded polyethyene machine travel roller, the preservative film that is transported by carry-over pinch rolls directly enters this device preparation micropore.
