Abstract
An one-pass technology for manufacture louvers with patterns on their both surfaces includes such technological steps as extruding plastics as raw material to obtain long strip sheet as basic material, pressing patterns on its both surfaces with a press having built-in cooler, cooling for fixating the patterns, shaping to obtain predefined width, air cooling, sizing and cutting.
Description
The present invention relates to a kind of manufacture method of louvers of jalousie.
The manufacture method of louvers of jalousie in the past, some can make the louvers of jalousie of tool decorative pattern, consult Fig. 1, it is a kind of schematic flow sheet of the piece making method of sun blind in the past, it mainly is by extruder 11 the plastic raw materials extrusion to be formed the rectangular blade 12 of the continuous shape of tool, this rectangular blade 12 can form decorative pattern after upward making a pair of knurling tool 13 rollings that are provided with predetermined pattern through the surface, wherein, for avoiding before the rectangular blade 12 of the continuous shape of extruder 11 extrusions arrives knurling tool 13, temperature reduces the carrying out that is unfavorable for embossing too much, knurling tool 13 can be preheated to a predetermined temperature, can melt a little when being subjected to knurling tool 13 impressions, be beneficial to the formation of decorative pattern with the rectangular blade surface of box lunch.And form on the rectangular blade 12 after the decorative pattern, cooled off through a cooling device 14 again, then through the drawing of a cylinder 15, and, can make louvers of jalousie 17 with decorative pattern through the cutting an of guillotine 16.The manufacture method of aforementioned louvers of jalousie in the past, it can only make the louvers of jalousie 17 of tool single face decorative pattern, and can't produce the product of the two-sided decorative pattern of tool, therefore, the outward appearance of its goods visually with on the commercial value all has certain restriction, moreover, for strengthening the effect that decorative pattern forms, it is with the manufacture of knurling tool 13 heating, and not only many one machining clearances also can consume the useless unnecessary energy virtually.
Order of the present invention part utilizes the energy and time processing promptly to can be made into the manufacture method of the louvers of jalousie of the two-sided decorative pattern of tool providing a kind of filling.
The manufacture method of a kind of louvers of jalousie of the present invention is characterized in that comprising the following steps:
One: get material and make continuous rectangular flat substrates: get plastic raw materials and be heated to predetermined temperature and extrusion continuously, make and have the two continuous rectangular flat substrates that deviate from the side with extruder with extruder:
Two: carry out phase I cooling and deviate from side system in base material two and establish lines: aforementioned substrates is after leaving extruder, one inside of the warp let-off immediately has the embossing device of cooling circuit before the degree of cooling, deviate from the side roll extrusion in base material two and form two-sided lines, again substrate surface is cooled to the temperature that can make its typing;
Three: carry out the second stage cooling: the base material of the two-sided lines of aforementioned tool is introduced a ventilation type cooling device, it is cooled off fully;
Four: count chi, cut: the base material of the two-sided lines of tool that this cools off fully draws with feeding machine to be got preset distance and borrows cutting means to cut, and can make the curtain sheet of tool predetermined length.
The manufacture method of described louvers of jalousie, it is characterized in that: this embossing device is two groups of knurling tools of this base material two side faces of roll extrusion respectively, each knurling tool group has a metal roller, is formed with cooling circuit in this metal roller, and circulation has cooling fluid in cooling circuit.
The manufacture method of described louvers of jalousie is characterized in that: this continuous rectangular flat substrates is sent on the path of embossing device and is covered with a cover cap.
By above explanation as can be known, sun blind piece making method of the present invention, be to take advantage of this base material 3 to leave behind the extruder 2 before the degree of cooling, by two groups of staggered base material 3 two sides 31 of being located at, knurling tool group 41 on 32,42 with base material 3 two sides 31,32 compactings form decorative pattern, just, it is the temperature when keeping base material 3 to leave extruder 2, with knurling tool group 41,42 are directly impressed in base material 3 surfaces, and in knurling tool group 41,42 metal roller 411, establish with cooling circuit 413 421 inside, 423, can be not with knurling tool group 41, under the situation of 42 heating, the lines that the compacting lines are analysed clearly on base material 3 two sides.Therefore, the present invention can make the temperature of 2 pairs of base materials of extruder, 3 heating fill a part application, and must embossing device 4 not heated again, and, can on base material 3, suppress the louvers of jalousie that forms the two-sided decorative pattern of tool by embossing device 4 of the present invention.
The present invention is described in detail below in conjunction with drawings and Examples:
Fig. 1 is a kind of manufacturing process signal of the piece making method of sun blind in the past.
Fig. 2 is a manufacturing process schematic diagram of the present invention.
Consult Fig. 2, the sun blind piece making method of embodiment mainly comprises the following steps:
One, get material and make continuous rectangular flat substrates:
Polypropylene) or PVC (Polyvinyl chloride:, put it into extruder 2 and be heated to predetermined melt temperature and be pressed into and have the two continuous rectangular flat substrates 3 that deviate from side 31,32 take PP (PolyProPylene: polyvinyl chloride) for raw material;
Two, carry out phase I cooling printing pattern on base material simultaneously:
Aforementioned continuous rectangular flat substrates 3 is after leaving extruder 2 before the degree of cooling, by crawler-tread, constantly be sent to an embossing device 4 and carry out embossing, wherein descend too soon for the temperature that prevents base material 3, this base material 3 is sent on the path of embossing device 4 and is covered with a cover cap 41; And in this enforcement, this embossing device 4 comprises two groups of knurling tool groups 41,42, two knurling tool groups 41,42 have a metal roller 411 respectively, 421 and one rubber roll 412,422, wherein the metal roller 411 of this knurling tool group 41 corresponds respectively to base material with rubber roll 412 and deviates from side 31 for 3 liang, 32 and clamping on base material 3, knurling tool group 42 is located near this knurling tool group 41, big as for its assembling and aforementioned manner to identical, difference person is, its metal roller 421 is the shape that staggers mutually with the metal roller 411 of rubber roll 422 assembling positions and knurling tool group 41 with rubber roll 412, whereby, when base material 3 by crawler-tread, through this two knurling tools group 41, after 42 roll extrusion, can be in base material 3 two side faces 31, impress lines on 32, make base material 3 form the two-sided decorative pattern of tool;
And, promptly finalize the design for making the decorative pattern that impression comes out on the base material 3, in this metal roller 411,421, be provided with a cooling circuit 413,423, by in cooling circuit 413,423, constantly circulating with cooling fluid, base material 3 surface temperatures can be reduced to the temperature that can make its typing, after base material 3 was through 41,42 roll extrusion of knurling tool group, the lines that its surface forms can be finalized the design rapidly.
Three, moulding:
The base material 3 of the two-sided decorative pattern of abovementioned steps two tools is introduced in the workbench 5, made it form proper width;
Four, carry out the second stage cooling:
Five, the meter chi, cut:
