Description

Technical Field

[0001] The utility model relates to the technical field of spinnerets, in particular to a novel combined spinneret for producing non-woven fabrics. Background Art

[0002] Non-woven fabrics, also known as non-woven fabrics, needle-punched cotton, needle-punched non-woven fabrics, etc., are made of polyester fibers, polyester fibers (abbreviated as: PET) and are made through a needle-punching process. They can be made into different thicknesses, feels, hardness, etc. Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, flame-retardant, non-toxic and odorless, low-priced, recyclable, etc. They can be used in different industries, such as sound insulation, heat insulation, electric heaters, masks, clothing, medical and filling materials, etc.

[0003] In the production process of non-woven fabrics, the viscous polymer melt or solution needs to be transformed into a thin flow with a specific cross-section through micropores through a spinneret, and then solidified by a coagulation medium such as air or a coagulation bath to form filaments. Traditional spinnerets are all integrated in design. Although the integrated spinneret is relatively strong, it is not easily damaged during use.

[0004] For example, the utility model patent with authorization announcement number CN211771673U discloses a polyester non-woven fabric spinneret that is easy to clean. The device achieves the effect of supporting the inner ring plate by setting an outer ring plate and a connecting plate, achieves the effect of polyester non-woven fabric production through the inner ring plate and the spinneret hole, achieves a waterproof effect through the first waterproof layer, and achieves an effect of increasing the corrosion resistance of the plate body through the corrosion-resistant layer. The spinneret is easy to clean, and when placed, debris is not easy to enter the spinneret, making it convenient for people to use.

[0005] However, in actual use, when processing different products, different sizes may be required, and the spinneret with the corresponding aperture needs to be replaced for processing. At this time, the entire spinneret needs to be replaced, which increases the processing cost. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figures 1 to 5 A new type of combined spinneret for non-woven fabric production includes: a spinneret sleeve 1, a mounting plate 2, a connecting plate 11 and a connecting plate 2 12 are installed in the lower half of the spinneret sleeve 1, a cooling chamber is formed between the connecting plate 1 11 and the connecting plate 2 12, a mounting plate 2 is also inserted in the spinneret sleeve 1, a plurality of groups of spinneret assemblies 3 are distributed and installed on the mounting plate 2, and the connecting plate 1 11 and the connecting plate 2 12 are provided with sockets at positions corresponding to the spinneret assemblies 3; a fixing mechanism 4 is arranged on the spinneret sleeve 1 for fixing the mounting plate 2, and air supply pipes 5 are installed at positions corresponding to the cooling chambers on both sides of the spinneret sleeve 1. In this embodiment, the air supply pipe 5 on either side is a cold air inlet, and the other air supply pipe 5 is an air outlet. The external cold air is introduced into the cooling chamber through the air supply pipe 5, which can accelerate the cooling and forming of the material entering the spinneret assembly 3.

[0024] The working principle of the utility model is as follows: when in use, the spinneret assembly 3 is mounted on the mounting plate 2, and then the mounting plate 2 is inserted into the spinneret sleeve 1, and the lower end of the mounting plate 2 is made to contact with the upper end of the connecting plate 12, and then the mounting plate 2 is fixed in the spinneret sleeve 1 by the fixing mechanism 4, and the installation work can be completed. The operation is simple and the disassembly is convenient, so as to facilitate the replacement of spinneret assemblies 3 of different models without the need for overall replacement, which can effectively reduce the processing cost and better meet the use requirements.

[0025] As a further solution, the spinneret assembly 3 includes an upper sleeve 31 and a lower sleeve 35, an upper connecting seat 32 is installed in the upper sleeve 31, and a lower connecting seat 36 is installed in the lower sleeve 35, and a plurality of spinnerets 34 are distributed and installed between the upper connecting seat 32 and the lower connecting seat 36. In this embodiment, a connecting threaded seat 33 is fixed to the outer side of the upper sleeve 31, and a plurality of connecting threaded holes 21 are distributed on the mounting plate 2, and the connecting threaded seat 33 is threadedly screwed into the connecting threaded hole 21.

[0026] During installation, select a suitable spinneret assembly 3 (i.e., the inner diameter of the spinneret 34 is compatible with the processing size of the product), and then screw the connecting threaded seat 33 on the outer side of the upper sleeve 31 into the connecting threaded hole 21 on the mounting plate 2 to complete the installation. After completing the installation of all spinneret assemblies 3, insert the mounting plate 2 into the spinneret sleeve 1, and wait for the mounting plate 2 to collide with the upper end of the connecting plate 2 12. At this time, the lower sleeve 35 is inserted into the socket on the connecting plate 1 11, and the upper sleeve 31 is inserted into the socket on the connecting plate 2 12 to complete the preliminary installation.

[0027] As a further solution, the fixing mechanism 4 includes multiple groups of fixing sleeves 43 installed on the side wall of the spinneret sleeve 1, and a fixed baffle 42 is slidably inserted in each of the fixing sleeves 43. The end of the fixed baffle 42 extends into the interior of the spinneret sleeve 1, and a fixed cover plate 44 is also installed at the end of the fixing sleeve 43. A fixing spring 45 is installed between the fixed cover plate 44 and the fixed baffle 42. A chamfer 423 is provided on one side of the fixed baffle 42 extending into the interior of the spinneret sleeve 1, and a pin hole 1 421 and a pin hole 2 422 are provided at the upper end of the fixed baffle 42. A fixed pin 41 is slidably inserted at the corresponding position on the spinneret sleeve 1.

[0028] The working principle of the fixing mechanism 4 is as follows: when the mounting plate 2 needs to be inserted, the fixing baffle 42 is pushed to retract. At this time, the fixing baffle 42 pushes the fixing spring 45 to compress. When the end of the fixing baffle 42 is flush with the inside of the spinneret 1, the fixing latch 41 is pushed down to insert it into the second pin hole 422, which can prevent the fixing baffle 42 from extending into the spinneret 1. After the mounting plate 2 is inserted into the spinneret 1, the fixing latch 41 is lifted. At this time, the fixing spring 45 is restored, pushing the fixing baffle 42 to extend into the spinneret 1, thereby pressing the mounting plate 2. Subsequently, the fixing latch 41 is pushed down to insert it into the first pin hole 421, and the installation work can be completed. The operation is simple and the mounting plate 2 can be disassembled conveniently to facilitate the replacement of the spinneret assembly 3 on the mounting plate 2. When processing products of different models, there is no need to replace the entire product, which can effectively reduce the processing cost and better meet the use requirements.
