As shown in fig. 1-5, an extrusion pre-lip for producing a sidewall comprises three glue outlets, namely an upper glue outlet 4, a lower glue outlet 5 and a middle glue outlet 6, arranged on an extrusion pre-lip 2; go up glue outlet 4 and glue outlet 5 down and stand side by side, go up one side of glue outlet 4 and one side of glue outlet 5 down all with well glue outlet 6 is connected with the same one side, go up glue outlet 4 and glue outlet 5 down and go out the same glue, well glue outlet 6 goes out another glue.
Through having increased out gluey passageway, reduced the play gluey speed of every passageway, and then reduced extrusion temperature.
In order to ensure the consistency of products with the same glue, the upper glue outlet 4 and the lower glue outlet 5 are arranged in parallel up and down. In order to avoid contact in advance, a rubber blocking plate is arranged at the joint of the upper rubber outlet 4 and the lower rubber outlet 5.
An extruding machine comprises a mounting rack 1, the extruding pre-opening type arranged on the mounting rack 1 and three screw extruding channels 3 arranged on the mounting rack 1.
In order to smoothly extrude the glue, the screw extrusion channel 3 comprises a sleeve 31, a driving motor 32 arranged on the sleeve 31, an extrusion screw 33 arranged in the sleeve 31 and connected with an output shaft of the driving motor 32, and a feeding hopper 34 arranged on the sleeve 31; the gum is added through a feed hopper 34. The driving motor 32 drives the extrusion screw 33 to rotate in the sleeve 31, so as to push the glue to move in the sleeve 31, and then the glue reaches the glue outlet of the extrusion pre-opening type 2, and further the glue is extruded smoothly.
Further, in order to reduce the extrusion temperature of the middle screw extrusion channel, the inner diameter of the middle screw extrusion channel is 200 mm, and the inner diameters of the upper screw extrusion channel and the lower screw extrusion channel are 120 mm.
In order to increase the temperature of the glue body and facilitate the melting of the glue, the extrusion screw 33 comprises a screw body and an extrusion spiral sheet wound on the screw body, and the winding distance of the extrusion spiral sheet on the screw body, which is closer to one end of the extrusion pre-opening type, is smaller.
In order to increase the production efficiency, two sets of glue outlets and screw extrusion channels 3 are vertically and symmetrically arranged on the extrusion pre-opening die.
Because the outlet channel size of the upper glue outlet 4 and the lower glue outlet 5 on the extrusion pre-opening type 2 is obviously different, the glue outlet area of the upper glue outlet 4 is smaller than that of the lower glue outlet 5, so that the internal pressure of the upper glue outlet 4 is increased, and the rotating speed of the driving motor of the upper screw extrusion opening channel is lower than that of the driving motor of the lower screw extrusion opening channel. The rotating speed of a driving motor of the upper screw extrusion port channel is reduced, so that the internal pressure of the upper glue outlet 4 can reach a balanced state.
In order to verify the effect, 5 kinds of sidewalls with different widths and thicknesses are selected for test production, and the following effects are achieved:
therefore, compared with the existing equipment, the production efficiency of the device is greatly replaced, and the glue outlet temperature is greatly reduced.
Those of ordinary skill in the art will understand that: the discussion of any embodiment above is meant to be exemplary only, and is not intended to suggest that the scope of the invention (including the claims) is limited to these examples; within the idea of the invention, also combinations between technical features in the above embodiments or in different embodiments can be made, steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.
