Detailed Description
For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1 and 2, a method for producing a polyethylene film includes a movable nozzle and a transfer mechanism 3;
the number of the movable nozzles is multiple, and the movable nozzles are sequentially arranged above the conveying mechanism 3 along the running direction of the conveying mechanism 3;
the moving direction of the movable nozzle is vertical to the running direction of the conveying mechanism 3;
and in the running process of the conveying mechanism 3, respectively controlling each movable nozzle to carry out cross lapping according to a preset rule to obtain a corresponding polyethylene film.
The movable nozzle comprises a nozzle 1 and a slide rail 1;
the nozzle 1 is arranged on the slide rail 1 and is connected with the slide rail 1 in a sliding manner;
the nozzle 1 is arranged above the conveying mechanism 3, and the sliding rail 1 is connected with the conveying mechanism 3.
The length of the slide rail 1 can be adjusted, and the moving speed and the moving time of the nozzle 1 on the slide rail 1 can be adjusted.
The conveying mechanism 3 comprises a conveyor belt 31 and a roller 32, and the conveying speed of the conveyor belt 31 is adjustable.
According to the preset rule, each movable nozzle is respectively controlled to carry out cross lapping, and the corresponding polyethylene film obtained specifically comprises:
and respectively controlling the moving range of each movable nozzle to carry out cross lapping to obtain the corresponding wide polyethylene film.
According to the preset rule, each movable nozzle is respectively controlled to carry out cross lapping, and the corresponding polyethylene film obtained specifically comprises:
and respectively controlling the number of the movable nozzles and the moving speed of each movable nozzle to carry out cross lapping to obtain the corresponding polyethylene film.
Specifically, assuming that the ejection amount (denoted by M) of a single nozzle is 250 grams per minute, the specific ejection amount may vary due to the difference in the size of the ejection hole; assuming that the lapping width (using letter L) of a single nozzle is 0.6 m, the lapping width can be different according to the parameter settings (orifice size, swing frequency and the like) of the nozzle; assuming that the number of nozzles (denoted by the letter N) is 4, the distance between two adjacent nozzles (denoted by the letter D) is 1.2 meters.
In accordance with the above conditions, how to apply the process provided by the present invention, a uniform polyethylene film web having a total width (indicated by the letter Z) of 2 meters and a grammage (indicated by the letter G) of 70 grams per square meter was made.
According to the above conditions, 4 nozzles are provided, so that 4 nozzles need to be moved in a coordinated and orderly manner to ensure that the grammage of the laid fiber web is the same over the entire width. Referring to fig. 3, the web formed by the first nozzle 11, the second nozzle 12, the third nozzle 13 and the fourth nozzle 14, as can be seen from the schematic view of fig. 3, the two layers of webs sprayed from the single nozzles are arranged at each position of the stacked web, so that the grammage of each position of the obtained large-width web is the same as long as the moving speed of each nozzle is the same and the advancing speed of the bottom curtain is not changed. The number of layers of the stack can be set according to specific equipment parameters, and the two layers are set for calculation only in the embodiment.
According to the above conditions, in order to make a polyethylene film fiber web with a total width of 2 meters and a net forming grammage of 70 per square meter, the advancing speed of the bottom curtain and the moving speed of the nozzle need to be adjusted; the advancing speed of the bottom curtain (indicated by the letter V1) is calculated as:
V1＝[N*M]/[G*Z]＝(250*4)/(70*2)＝7.14m/min；
the nozzle travel speed (indicated by the letter V2) is:
V2＝V1/L＝[N*M]/[G*Z]/L＝(250*4)/(70*2*0.6)＝11.90m/min；
according to the embodiment of the invention, since the distance between the adjacent nozzles is larger than the lapping width of the single nozzle (D > L), according to the schematic diagram 3, in order to ensure that the nets sprayed by the adjacent nozzles are just aligned, the reciprocating movement of the nozzles cannot be completely synchronized, and a certain delay time (denoted by T) is required to be set. Therefore, the turning point of each nozzle on the same side of the bottom curtain (left side or right side of the bottom curtain) can be set as the starting point of each nozzle, and when the first nozzle 11 starts to move from the starting point at the speed of V2 while the bottom curtain keeps continuously advancing at the speed of V1, the second nozzle 12 needs to start to move after a certain time (i.e. delay time T) after the first nozzle 11 starts to move from the starting point, so as to ensure that the edge of the net formed by the first nozzle 11 and the second nozzle 12 is exactly aligned. By calculation, T ═ D-L ]/V1 ═ (1.2-0.6)/7.14 ═ 0.084 min ═ 5.04 sec. By analogy, the third nozzle 13 needs to start moving from the starting point after T time when the second nozzle 12 starts moving from the starting point, and the fourth nozzle 14 needs to start moving from the starting point after T time when the third nozzle 13 starts moving from the starting point.
Under the condition that the ejection quantity of a single nozzle, the lapping width of the single nozzle, the number of nozzles, the distance between two adjacent nozzles and the number of lapping layers are not changed, if the gram weight of a net is required to be adjusted, only the advancing speed of the bottom curtain, the moving speed of the nozzles and the delay time among the nozzles need to be adjusted, and hardware equipment does not need to be modified; if the total width of the net is needed, only the advancing speed of the bottom curtain, the moving speed of the nozzles and the delay time among the nozzles need to be adjusted, and meanwhile, the round-trip point of the nozzles is adjusted, and hardware equipment does not need to be modified.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
