Abstract
The invention discloses a method for manufacturing a medical PE thin film four-side tear-off air-permeable adhesive tape. The method comprises the step of: perforating the surface of medical PE thin film on which a medical adhesive is coated by heating a burr roller by utilizing a heat transfer oil carrier. The method is characterized in that: a circulation path of heat transfer oil is changed; the interlayer of the inner wall of the roller is removed from the internal structure of the roller of the burr roller; the heat transfer oil flows in the roller directly; the diameters of the inlet and the outlet in the heat transfer oil circulation path are expanded so as to expand the channel of the heat transfer oil; the roller is filled with the heat transfer oil; the heat transfer oil flows smoothly to speed up the circulation speed of the heat transfer oil so that the burr roller is heated uniformly; and holes pressed on the medical PE thin film has the characteristics of uniform size, regular shape and orderly arrangement. The times for washing the roller of the burr roller and the heat transfer oil circulation path are reduced greatly, namely once per year; and the longitudinal direction, the transverse direction, the upper, lower, left and right surfaces of the medical PE thin film manufactured by the method of the invention can be torn linearly.
Description
Technical field
The present invention relates to a kind of conduction oil circulating heater, particularly disclose the manufacture method of the tearable breathable adhesive tape in a kind of medical PE film four sides.
Background technology
Tearable in order to reach medical PE film adhesive tape four sides, existing technology is being coated with the PE film surface punching of medical adhesive, to reach tearable purpose by heating burr roller.Existing burr roller conduction oil loop heating system is to make it circulation by inner wall of rotary drum interlayer input conduction oil.Because interlayer is little, wall is thin, after the long-time heating, because the conduction oil flowing velocity is slow, be subjected to temperatures involved very easily at burr roller inwall knot charcoal, result in blockage, cause the heating of burr roller inhomogeneous, finally influence the shape of hole, it is crooked that the hole size difference can make adhesive tape produce when tearing.
Summary of the invention
The objective of the invention is to overcome product that prior art produces only laterally when smooth tearing and longitudinal tear and crooked defective makes medical film adhesive tape four sides tearable, but also promptly reach vertically and horizontal smooth tearing all up and down.
The present invention is achieved in that the manufacture method of the tearable breathable adhesive tape in a kind of medical PE film four sides, comprise and utilize conduction oil carrier heating burr roller being coated with the medical PE film surface punching of medical adhesive, it is characterized in that: the circulating path that changes conduction oil, cancellation roller inwall interlayer in the roller internal structure of burr roller, conduction oil directly trickles in roller, the turnover bore that enlarges in the described conduction oil circulating path is 227mm, enlarge the passage of conduction oil, make full conduction oil in the roller, conduction oil flows smooth and easy, accelerate the conduction oil circulation rate, therefore the roller inwall of burr roller can not tied charcoal, prevent that conduction oil from stopping up, the burr roller is heated evenly, the hole size that extrudes on medical PE film is even, regular shape, marshalling.Clean the roller of burr roller and the number of times of conduction oil circulating path and reduce greatly, cleaned once in 1 year.But the medical PE film vertical and horizontal of making through the inventive method are the equal smooth tearing in four sides up and down.
The invention has the beneficial effects as follows:
1) technique effect: after improving through the present invention, the most direct effect is no matter the film adhesive tape is vertically or the horizontal equal smooth tearing easily in four sides up and down after the punching of burr roller, and outward appearance is beautiful, meets consumers' demand.
2) social effect: through medical film adhesive tape that the present invention produces very advantageous in the like product at home, and can compare favourably with the similar adhesive tape of 3M of advanced level in the world, therefore in the same industry, has very strong competitiveness, estimate that annual turnover can increase by 30～50%, particularly export trade output speedup is obvious, has powerful market in American-European countries.
3) economic effect: at first because its economic benefit of increase of sales volume can be significantly increased, can increase by 2,000,000 every year approximately.Secondly heating circulation system of the present invention is because should not tie charcoal, so the number of times of the roller of cleaning burr roller and the circulating path of conduction oil reduces greatly, originally will clean in 1 month 1 time, can extend to 1 year now and clean 1 time, save human and material resources, improved production capacity simultaneously again.Only production cost can be saved about 20,000 yuan every year.
Description of drawings
Fig. 1 is 200 times of enlarged drawings of void shape of the tearable breathable adhesive tape in medical PE film four sides of the inventive method manufacturing;
Fig. 2 is that the hole of the tearable breathable adhesive tape in medical PE film four sides of the inventive method manufacturing is arranged 60 times of enlarged drawings.
The specific embodiment
Existing technology is being coated with the PE film surface punching of medical adhesive, to reach tearable purpose by heating burr roller.
Heat-conducting oil heating circulating path in the roller of the inventive method change burr roller, cancellation roller inwall interlayer in the roller internal structure of burr roller, conduction oil directly trickles in roller, and the turnover bore that enlarges in the conduction oil circulating path is 227mm, enlarges the passage of conduction oil, make full conduction oil in the roller, conduction oil flows smooth and easy, accelerate the conduction oil circulation rate, so the roller inwall of burr roller can not tied charcoal, prevent that conduction oil from stopping up, and is heated evenly the burr roller.After the burr roller adopts the heating circulation system heating back of the inventive method that medical PE film is implemented nip drum, the hole of getting as shown in Figure 1, the hole marshalling, the shape size is roughly the same, as shown in Figure 2, tears about up and down in length and breadth and can both guarantee straight line, appearance looks elegant, easy to use.And adopt the roller of the inventive method product cleaning burr roller and the number of times of conduction oil circulating path to reduce greatly, cleaned once in 1 year.The product quality of its manufacturing obviously is better than the product with prior art production, and the product quality that the present invention produces is subjected to affirming and welcoming of user.
