Problems solved by technology

Because the inner runner and spinneret holes inside the spinneret are difficult to process, and the grinding is difficult or even impossible, the liquid material entering the inner runner will generate turbulence in it, resulting in uneven filament discharge and affecting product quality.
At the same time, the inner runner and spinneret holes are not easy to clean, which affects the service life of the equipment

Embodiment Construction

[0027] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] see Figure 1-5 shown, where figure 1 and figure 2 The dissection location is different. Above-mentioned a processing method for spinneret, comprises the following steps:

[0029] (1) Divide the first plate body into two along the longitudinal centerline direction, respectively on the butt joint surfaces of the two first sub-boards 1 (the butt joint surfaces mentioned here refer to the two first sub-boards 1 facing each other) The first groove 2 is processed on the side), so that after the two first sub-boards 1 are spliced, the first grooves 2 on both sides are spliced ​​with each other to form an inner runner 3 . The inner runner 3 extends along the longitudinal centerline of the first plate body and is closed at both ends, and the inner runner 3 is closed at the top and open at the bottom. That is, the inner runner 3 is entirel...

Abstract

The invention discloses a processing method used for a spinneret plate. A first plate body is divided into two parts, a first groove and a second groove are processed, the processing difficulty and the processing cost are reduced, the processing efficiency is improved, the grinding difficulty is reduced, and the grinding precision and the inner wall smoothness are improved; holes are cyclically formed at intervals in a wire cutting manner, the situation that due to direct drilling, the processing difficulty is large and the processing precision is low is avoided, grinding is also convenient after separating, and the inner wall precision is improved; and finally a processed second branch plate is mounted in the second groove to form an air gap, and a processed third plate body with a feeding hole is mounted at the bottom of the first plate body. The spinneret plate manufactured through the method is uniform in spinning and high in spinning quality, meanwhile, cleaning is convenient, andthe service life is long.

Description

technical field [0001] The invention relates to a spinning plate and a processing method thereof. Background technique [0002] Spinnerets are generally used for the production of nonwovens by the melt blown method. Because the inner runner and spinneret holes inside the spinneret are difficult to process and difficult to grind, even they cannot be polished, resulting in turbulent flow of the liquid material entering the inner runner, resulting in uneven filament discharge and affecting product quality. At the same time, the inner runner and spinneret holes are not easy to clean, which affects the service life of the equipment. Contents of the invention [0003] The first object of the present invention is to provide a processing method for the spinneret, which is less difficult to process the first groove and the spinneret hole, less difficult to grind after disassembly, high grinding precision, easy to clean, and evenly sprayed , Higher product quality. [0004] In or...
