Further, the whole body is in a cuboid shape.
Furthermore, sixteen spinneret orifices are arranged in a straight line at equal intervals.
Further, the aperture of the spinneret orifice is 0.6 mm.
Furthermore, a mesh is arranged on the side wall of the precooling cover.
Further, the pre-cooling cover is in a flaring shape.
Furthermore, the body is provided with an assembly hole in a penetrating way.
Furthermore, the side of the body is provided with an assembly groove.
Further, the constant pressure groove is arranged at the bottom of the glue injection groove.
The utility model has the advantages that: the utility model discloses a fixed precooling cover that sets up on the body, make precooling cover set up on the discharge end that is close to the spinneret orifice, through spinneret orifice spun filiform product when leaving the body, can obtain a precooled process in precooling cover, compared with the filiform product in the traditional art leaves the body promptly quench, the utility model discloses can reduce the hollow rate of product to a great extent after the precooling to the quality of product has been improved; on the other hand, the utility model discloses a seted up the glue injection groove on the body is close to the feed end of spinneret orifice, carry out the injecting glue for all spinneret orifices simultaneously through the glue injection groove, and communicate constant voltage groove between two adjacent spinneret orifices, further balance the hydraulic pressure between two adjacent spinneret orifices, furthest balances the pressure between each spinneret orifice to make spun strand silk product thickness balanced, further improved the quality of product.
Drawings
Fig. 1 is an overall structure front view of the present invention;
fig. 2 is a rear view of the overall structure of the present invention.
The reference signs are:
the body 1 is provided with a plurality of grooves,
the device comprises a spinneret orifice 11, a glue injection groove 12, a constant pressure groove 13, a pre-cooling cover 14, an assembly orifice 15 and an assembly groove 16.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in figure 1 and figure 2 a simple and easy extruder bush that expands production ability, including body 1, body 1 wholly is the cuboid type, runs through on the body 1 and has seted up sixteen spinneret orifices 11, and sixteen spinneret orifices 11 are sharp equidistance and arrange, and the aperture of spinneret orifice 11 is 0.6mm, and this design can make the productivity reach 400 and give birth to 600KG/H, thereby makes the utility model discloses a structure is simple and easy, and the productivity is higher.
The feeding end of the body 1 close to the spinneret orifices 11 is provided with the glue injection groove 12, all the spinneret orifices 11 are injected with glue through the glue injection groove 12, and the feeding end of each spinneret orifice 11 is positioned in the glue injection groove 12; constant pressure groove 13 is connected to the intercommunication between two adjacent spinneret orifices 11, and constant pressure groove 13 is located the bottom setting of annotating gluey groove 12, and constant pressure groove 13 is close to the feed end setting of spinneret orifice 11, and constant pressure groove 13 can further balance the pressure between each spinneret orifice 11 to make spun strand silk product thickness balanced, further improved the quality of product.
A pre-cooling cover 14 is fixedly arranged on the discharging end, close to the spinneret orifice 11, of the body 1, the pre-cooling cover 14 is arranged around the discharging end of the spinneret orifice 11, meshes are formed in the side wall of the pre-cooling cover 14, and hot air in the pre-cooling cover 14 and cold air outside can be well convected through the meshes, so that heat exchange is realized, and the pre-cooling of a strand silk product just sprayed out of the body 1 is achieved; precooling cover 14 is the flaring form, and the filiform product through spinneret 11 spun can obtain the process of a precooling in precooling cover 14 when leaving body 1, and the filiform product leaves body 1 with traditional technique and is shock-cooled and compare, the utility model discloses can reduce the hollow rate of product to a great extent after the precooling to the quality of product has been improved.
