Description

Technical Field

[0001] This utility model relates to the field of spinning component technology, and in particular to a connection structure between a distribution plate and a spinneret. Background Technology

[0002] The spinneret is one of the most important components of the spinning assembly. After being distributed by the distribution plate, the high-pressure molten material enters the spinneret's orifices, and then is ejected from the orifices. After cooling, it solidifies and takes shape into fibers. However, the high-pressure molten material impacts the spinneret as it flows towards it, which may cause deformation. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a connection structure between a distribution plate and a spinneret. There are connecting posts and connecting holes that fit together between the spinneret and the distribution plate. The connecting posts are hollow. After an extrusion member is inserted into the connecting posts, the connecting posts are squeezed to fit tightly against the connecting holes. Thus, the connecting force between the connecting posts and the connecting holes can be used to prevent the spinneret from deforming.

[0004] Technical solution: To achieve the above objectives, the present invention provides a connection structure between a distribution plate and a spinneret, comprising a spinneret, a distribution plate, and an extruder. A connection hole is provided on the side of the distribution plate facing the spinneret, and a connecting post is provided on the side of the spinneret facing the distribution plate. The connecting post is inserted into the connection hole. The connecting post has a hollow channel. After the extruder enters the hollow channel, it extrudes and deforms the connecting post to fit tightly against the connection hole.

[0005] Furthermore, a curved sheet is provided on the top of the connecting column, and the curved sheet protrudes towards the hollow channel; after the extruder enters the hollow channel, it extrudes the curved sheet to a flattened state, so that the outer periphery of the curved sheet expands to fit tightly against the connecting hole.

[0006] Furthermore, an annular groove is provided on the outer cylindrical surface of the connecting column, and the annular groove is located below the curved surface piece, so that the outer periphery of the curved surface piece forms a flange.

[0007] Furthermore, the flange on the outer periphery of the curved sheet has several circumferentially distributed slits.

[0008] Furthermore, the extrusion component is a bolt, and the hollow channel has an internal thread structure; the extrusion component is screwed into the hollow channel through threaded engagement, and the end of the extrusion component can extrude a curved sheet as the extrusion component rotates.

[0009] Furthermore, the distribution plate has a single connecting hole located at the center of the distribution plate; the spinneret has a single connecting post located at the center of the spinneret.

[0010] Furthermore, the distribution plate has a plurality of connecting holes arranged in a ring array; the spinneret plate has a plurality of connecting posts arranged in a ring array.

[0011] Beneficial effects: The present invention provides a connection structure between a distribution plate and a spinneret, wherein there is a connecting post and a connecting hole that fit together between the spinneret and the distribution plate. The connecting post is hollow and has a curved plate at the top. When the bolt is screwed into the connecting post, the bolt will squeeze the curved plate, causing the curved plate to deform to a flattened state. This causes the outer periphery of the curved plate to expand and fit tightly against the connecting hole, increasing the friction between the connecting hole and the connecting post. Thus, the friction between the connecting post and the connecting hole can be used to prevent the spinneret from deforming. Attached Figure Description

[0012] Appendix Figure 1 This is a schematic diagram showing the connection between the distribution plate and the spinneret.

[0013] Appendix Figure 2 This is a structural diagram of the connecting column. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] As attached Figures 1 to 2 The aforementioned connection structure between a distribution plate and a spinneret includes a spinneret 1, a distribution plate 2, and an extruder 5. A connecting hole 3 is provided on the side of the distribution plate 2 facing the spinneret 1, and a connecting post 4 is provided on the side of the spinneret 1 facing the distribution plate 2. When the spinneret 1 and the distribution plate 2 are assembled in a spinning assembly, the connecting post 4 is inserted into the connecting hole 3. The connecting post 4 has a hollow channel 6. When the extruder 5 enters the hollow channel 6, it compresses the connecting post 4, causing it to deform with an expanding tendency, thus expanding the connecting post 4 to fit tightly against the connecting hole 3. Therefore, when the spinneret 1 is subjected to the impact force of the high-pressure melt, the connecting force between the connecting post 4 and the connecting hole 3 can be used to prevent the spinneret 1 from deforming.

[0016] Specifically, as shown in the attached document Figure 1As shown, a curved plate 7 is provided on the top of the connecting post 4, and the curved plate 7 is integrally connected to the connecting post 4. One side of the curved plate 7 is opposite to the hollow channel 6. Before the extruder 5 enters the hollow channel 6, the curved plate 7 protrudes towards the hollow channel 6. After the extruder 5 enters the hollow channel 6, it will compress the curved plate 7 until it is nearly flat. As the curved plate 7 is gradually flattened from its protruding state, its outer periphery expands. The outer diameter of the connecting post 4 is the same as the diameter of the connecting hole 3. Before the extruder 5 enters the hollow channel 6, the outer periphery of the curved plate 7 is in contact with the inner wall of the connecting hole 3. However, after the extruder 5 enters the hollow channel 6 and compresses the curved plate 7 until it is nearly flat, the outer periphery of the curved plate 7 expands to fit tightly against the connecting hole 3. After the curved plate 7 is tightly attached to the connecting hole 3, if the connecting post 4 wants to move relative to the connecting hole 3, the frictional force between the connecting post 4 and the connecting hole 3 will be very large, thus preventing the connecting post 4 from moving relative to the connecting hole 3. Therefore, when the spinneret 1 is subjected to the impact of high-pressure melt, the frictional force between the connecting post 4 and the connecting hole 3 can prevent the spinneret 1 from deforming.

[0017] As attached Figure 2 As shown, an annular groove 8 is provided on the outer cylindrical surface of the connecting post 4, and the annular groove 8 is located below the curved surface piece 7, so that the outer periphery of the curved surface piece 7 forms a flange 9. If the annular groove 8 is not provided, the lateral contour surface of the connecting post 4 is a complete cylindrical surface, and the outer periphery of the curved surface piece 7 is part of this complete cylindrical surface, so the outer periphery of the curved surface piece 7 is not easily deformed. After the annular groove 8 is provided, the outer periphery of the curved surface piece 7 forms a flange 9, and the flange 9 is separated from the lateral contour surface of the connecting post 4 by the annular groove 8. Therefore, the outer periphery flange 9 of the curved surface piece 7 is more easily deformed, so that the curved surface piece 7 is more easily attached to the inner wall of the connecting hole 3. Furthermore, several slits 10 are distributed circumferentially on the flange 9 on the outer periphery of the curved surface piece 7. The slits 10 make the outer periphery flange 9 of the curved surface piece 7 more easily deformed.

[0018] The extrusion member 5 is a bolt, and the hollow channel 6 has an internal thread structure, that is, the hollow channel 6 is a threaded hole with an open bottom. The extrusion member 5 is screwed into the hollow channel 6 through the threaded engagement, and the end of the extrusion member 5 can compress the curved sheet 7 as the extrusion member 5 rotates. As the extrusion member 5 rotates in, it will gradually compress the curved sheet 7 until it tends to be flat.

[0019] In one embodiment, the distribution plate 2 has a single connecting hole 3 located at the center of the distribution plate 2; the spinneret 1 has a single connecting post 4 located at the center of the spinneret 1. Since the center of the spinneret 1 is most prone to deformation, if only a single connecting post 4 and a single connecting hole 3 are provided, then the single connecting post 4 and the single connecting hole 3 are located at the center.

[0020] In another embodiment, the distribution plate 2 has a plurality of connecting holes 3 arranged in a ring array; the spinneret 1 has a plurality of connecting posts 4 arranged in a ring array.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
