Abstract
The utility model belongs to the field of thin film preparation, and in particular relates to a low-temperature charging device on a BOPP (biaxially-oriented polypropylene) thin film preparation production line. The device comprises a charging pipeline, wherein one end of the charging pipeline is connected with a charging hole of a thin film production line; a fan is arranged at the other end of the charging pipeline; the charging pipeline is vertically provided with a hopper; a lower hole of the hopper is connected with a charging limiter; a cooler is arranged between the hopper and the fan. The low-temperature charging device is simple in structure; the charging temperature can be remarkably reduced; the quality of a thin film is improved by reducing the charging temperature.
Description
Technical field
The utility model belongs to film preparation field, relates in particular to low temperature feed arrangement on a kind of BOPP film preparation production line.
Background technology
BOPP film is a kind of very important flexible packing material, applies very extensive.BOPP film is colourless, odorless, tasteless, nontoxic, and has high tensile, impact strength, rigidity, obdurability and the good transparency.BOPP film surface can be low, before gluing or printing, needs to carry out sided corona treatment., BOPP film, after sided corona treatment, has good printing adaptability, can chromaticity printing and obtain exquisite appearance, thereby be commonly used for the surface material of laminated film.BOPP film also has deficiency, as easy accumulation static, there is no heat sealability etc.On the production line running up, BOPP film easily produces static, needs to install static remover.In order to obtain heat sealable BOPP film, can after BOPP film surface sided corona treatment, be coated with heat sealable resin adhesive liquid, as PVDC latex, EVA latex etc., also can coating solvent glue, also can adopt the method for extrusion coated or coextru-lamination to produce heat sealable BOPP film.This film is widely used in the packings such as bread, clothes, footgear, and the cover package of cigarette, books.The initiation tearing strength of BOPP film increases after stretching, but secondary tearing strength is very low, and therefore, BOPP film both ends of the surface can not leave any otch, otherwise BOPP film is at printing, the easy tear fracture of compound tense.After BOPP coating adhesive sticker, can produce tape, be the market of BOPP large usage quantity.
In the preparation process of BOPP film, there is very large problem to the quality of production of film in the temperature of charging material body, and conventional way is to adopt blower fan to blow and carry out coolingly the raw material after pulverizing, but effect is general.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of low temperature feed arrangement, is intended to reduce feeding temperature, improves the quality of film.
The utility model is to realize like this, a kind of low temperature feed arrangement, comprise feed pipe, one end of feed pipe is connected with film line charging aperture, the other end is provided with blower fan, feed pipe is vertically provided with hopper, and the lower port of described hopper is connected with charging limiter, between hopper and blower fan, cooler is installed.
Further, described cooler is cavity structure, and the tracheae parallel with feed pipe is set in cavity, is staggeredly equipped with up and down multiple dividing plates in cavity, and described dividing plate is vertical with tracheae.
Further, the diameter of described tracheae reduces gradually from air intake to air-out.
Further, described charging limiter is rotating wheel structure, and the upper and lower correspondence of swiveling wheel offers charging aperture and discharging opening, is provided with impeller in swiveling wheel, when vane rotary, alternately charging aperture is opened to discharging opening closure; Or charging aperture closure, discharging opening is opened.
Compared with prior art, beneficial effect is the utility model: the utility model is simple in structure, can significantly reduce the temperature of charging, by reducing feeding temperature, film quality is improved.
Accompanying drawing explanation
Fig. 1 is the device structure schematic diagram that the utility model embodiment provides;
Fig. 2 is the cross sectional representation of the utility model cooler;
Fig. 3 is the shape and structure schematic diagram of pore in the utility model cooler;
In figure, 1 is blower fan, 2 for cooler, 3 for hopper, 4 for charging aperture, 5 be limited material wheel, 6 for impeller, 7 discharging openings, 8 for feed pipe, 9 for film line charging aperture, 21 for cooling water inlet, 22 tracheaes, 23 for dividing plate, 24 for cooling water outlet, 25 be cavity.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As depicted in figs. 1 and 2, a kind of low temperature feed arrangement, comprise feed pipe 8, one end of feed pipe 8 is connected with film line charging aperture 9, the other end is provided with blower fan 1, feed pipe 8 is vertically provided with hopper 3, and the lower port of hopper 3 is connected with charging limiter 5, between hopper 3 and blower fan 1 cooler 2 is installed.Cooler 2 is cavity structure, the tracheae 22 that the interior setting of cavity 25 is parallel with feed pipe, as shown in Figure 3, the diameter of tracheae 22 reduces gradually from air intake to air-out, cavity 25 is interior is staggeredly equipped with multiple dividing plates 23 up and down, dividing plate 23 is vertical with tracheae 22, is provided with cooling water inlet 21 and cooling water outlet 24 on cavity 25 cavitys, and water is realized tortuous flowing by dividing plate from 23.As shown in Figure 1, charging limiter is rotating wheel structure, and the upper and lower correspondence of swiveling wheel offers charging aperture 5 and discharging opening 7, is provided with impeller 6 in swiveling wheel, when impeller 6 rotates, alternately charging aperture 4 is opened to discharging opening 7 closures; Or charging aperture 5 closures, discharging opening 7 is opened.
In the time of work, blower fan starts, and dries in feed pipe by the tracheae of cooler, in the cavity of cooler, for recirculated water circulates, conduct the problem that reduces gas in tracheae by heat, thus blowing cold air, vane rotary in swiveling wheel, alternately opens charging aperture discharging opening closure; Or charging aperture closure, discharging opening is opened.By control rotating speed size control charging number and speed.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
