Abstract
The utility model discloses an automatic moving mold head for the extruding equipment belonging to the field of plastic soft package, and the effective improvement based on the original T-shaped mold head is that the two ends are respectively arranged an electric amplitude modulating device with a sensing element to do the compensation movement, that is, when the T-shaped mold head moves to the left, the electric amplitude modulating device drives the sealing element to move to the right automatically and simultaneously, and when the T-shaped mold head moves to the right, the electric amplitude modulating device drives the sealing element to move to the left automatically and simultaneously, and the distance of the T-shaped mold head from the original position is the same as the modulating amplitude to compensate of the electric amplitude modulating device, therefore, the edge position of the plastic film or the sheet can always keep a line. The utility model with the advantages of reasonable structure, reliable running and level roll-up can solve the problem of uneven extruded film and heave in the roll material, ensuring the consistency of the surface quality of the extruded plastic film or the sheet and improving the production quality.
Description
One, technical field
The utility model relates to the improvement of the die head of extrusion equipment in the plastic flexible package industry.
Two, background technology
At present, because the influence of factors such as the accuracy of manufacture, thermal deformation, the gap of die lip has the surface roughness of certain deviation, die lip at width can be not quite identical in manufacture process for the T pattern head that extrusion equipment in the plastic flexible package industry (for example slobbering machine, extruder) is extruded usefulness usually.To the damage of die lip oral thermometer face, it is even that these factors all can have influence on the became uneven of the plastic sheeting extruded through T pattern head or sheet material when also having expressing technique pressure, the change of material flowability, high-temperature resin to stick to carbonization point on the die lip mouth, cleaning die lip mouth.When product batched, the surface of coiled material can occur uneven, was commonly called as " quick-fried muscle ", caused product rejection when serious.
Three, utility model content
The purpose of this utility model is will provide a kind of can solve the die head that moves about automatically that flat film is extruded became uneven, the coiled material that batches plays " quick-fried muscle " defective.
The purpose of this utility model is achieved in that it has T pattern head and the seal that is assemblied in the die lip of T pattern head, and it is characterized in that: it also has electronic amplitude modulation apparatus, and described electronic amplitude modulation apparatus is installed in the two ends of T pattern head respectively.In order to make the coiled material surface of batching rough " quick-fried muscle " can not occur, T pattern head is done back and forth reciprocating motion at its width when extruded plastic foil or sheet material, the material of became uneven can be superimposed upon on the original position when take-up, and the coiled material surface of batching like this will smooth unanimity.Yet because die head is reciprocating, its position, limit periodic waveform must occur and change, and causes the material of being extruded that is in both sides to use and wastes.Therefore, for the position, limit that makes the plastic sheeting extruded through T pattern head or sheet material keeps neat straight line, the spy makes improvements on the basis of original T pattern head, exactly at its two ends respectively mounting strap the electronic amplitude modulation apparatus of sensing element is arranged, make compensating motion by the electronic amplitude modulation apparatus that is installed in T pattern head two ends: promptly when T pattern head during to left movement, electronic amplitude modulation apparatus makes the automatic same moved further of seal to the right; When T pattern head moved right, electronic amplitude modulation apparatus made the automatic same moved further of seal---T pattern head leaves how many distances of original position, and electronic amplitude modulation apparatus will be made corresponding adjusting range and be compensated left.Like this, the position, limit of plastic sheeting or sheet material just can remain concordant straight line.
The utility model is rational in infrastructure, reliable, rolling is smooth, solved more effectively that flat film is extruded became uneven, the coiled material that batches plays the phenomenon of " quick-fried muscle ", thereby can guarantee the uniformity of the surface quality of extruded plastic foil or sheet material, further improve the quality of products, extensively model replaces the T pattern head of extrusion equipment in the present plastic flexible package industry.
Four, description of drawings
Fig. 1, be structural representation according to one of the embodiment that the utility model proposes;
Fig. 2, be two structural representation according to the embodiment that the utility model proposes.
Five, the specific embodiment
Below in conjunction with drawings and Examples structure of the present utility model is further described:
In extruding, because it is reciprocating along directions X that extruder 1 drives T pattern head 2, thereby then can not be fixed on the same position during T pattern head 2 work, so, base material width L by multiple width S of the pouring of T pattern head 2 extruded plastic foils or sheet material and moulding just also there is no fear of being consistent, it just must form a deviation H1 (as shown in Figure 1) or H2 (as shown in Figure 2) between the two in the process of motion: along with T pattern head 2 is offset left along directions X, plastic sheeting of extruding or sheet material will be offset to leaning on the leftmost position; Equally, along with T pattern head 2 is offset to the right along directions X, plastic sheeting of extruding or sheet material will cause occurring periodic waveform and change to by being offset on the rightmost position, cause the material of being extruded that is in both sides to use and the phenomenon that occurs wasting.
In order to overcome above defective, the utility model has been done improvement on the basis of original T pattern head 2, exactly at its two ends respectively mounting strap the electronic amplitude modulation apparatus 4 of sensing element is arranged, the seal 3 that drives the die lip that is assemblied in T pattern head 2 of sealing by the electronic amplitude modulation apparatus 4 that is installed in T pattern head 2 two ends is to make compensating motion: promptly when T pattern head 2 along directions X during to left movement, the induction of electronic amplitude modulation apparatus 4 by sensing element obtains the stroke instruction just makes the automatic same moved further of seal 3 to the right; Equally, when T pattern head 2 when directions X moves right, electronic amplitude modulation apparatus 4 then makes the automatic same moved further of seal 3 left by the induction acquisition stroke instruction of sensing element---that is to say, T pattern head 2 leaves how many distances of original position, electronic amplitude modulation apparatus 4 will be made corresponding adjusting range and be recompensed, this compensation magnitude is to move to the left or to the right by electronic amplitude modulation apparatus 4 driving seals 3 just to be achieved, thereby has eliminated by formed deviation H1 or H2 between the base material width L of multiple width S of the pouring of T pattern head 2 extruded plastic foils or sheet material and moulding.Like this, the position, limit of plastic sheeting or sheet material just can remain concordant straight line, and, significantly reduced the loss of extruded stock again.
Above-described only is preferential embodiment of the present utility model.Should be pointed out that to those skilled in the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, this also is considered as belonging to protection domain of the present utility model.
