[0001] The utility model belongs to the technical field of industrial spinning components, in particular to an assembly structure of a distribution plate and a spinneret for industrial spinning. Background Art

[0002] In the spinning assembly, the distribution plate distributes the melt to the spinneret, which then spins the melt into shape. The distribution plate and the spinneret are connected in the spinning box by axial crimping. Long-term exposure to high pressure and high temperature conditions can easily cause structural deformation of the spinneret, which not only affects the spinning pressure and reduces the spinning quality, but also easily causes melt leakage, affecting normal spinning production. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides an assembly structure of a distribution plate and a spinneret for industrial spinning, in which the distribution plate and the spinneret axis are connected and assembled through a plate center connector, which exerts a pulling force on the spinneret in the opposite direction to the deformation trend, thereby preventing the spinneret from being deformed under the influence of high pressure and high temperature conditions, ensuring sealing and improving the quality of the yarn.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides an assembly structure of a distribution plate and a spinneret for industrial spinning, comprising a distribution plate with a distribution hole and a spinneret with a spinneret hole, wherein the distribution hole and the spinneret are coaxially sealed and spliced to form a melt cavity that connects the distribution hole to the spinneret hole; and also comprises a plate center connector, wherein a seal is arranged at the joint between the distribution plate and the spinneret, and the distribution plate and the spinneret are connected by feeding through the plate center connector and axially shifted toward each other to extrude the seal to seal the melt cavity.

[0005] Furthermore, the connection position of the plate center connection piece is located at the plate center of the distribution plate and the spinneret plate.

[0006] Furthermore, the plate center connecting piece includes a threaded rod portion, a column rod portion and a hexagonal mounting head which are connected in sequence; a column hole is provided at the center of the distribution plate, and a threaded hole is provided at the center position of the spinneret, the threaded rod portion passes through the column hole and is screwed into the threaded hole, and the column rod portion is inserted into the column hole; the plate center connecting piece is rotated and fed relative to the spinneret thread, so that the distribution plate and the spinneret are axially shifted toward each other to achieve splicing and fixation.

[0007] Furthermore, a mounting head hole which is concentrically connected to the column hole is also provided at the center of the distribution plate, and the hexagonal mounting head is hidden in the mounting head hole.

[0008] Furthermore, the sealing member comprises an outer sealing gasket and an inner sealing gasket, wherein the outer sealing gasket is sealingly arranged on the outer ring of the melt cavity, and the inner sealing gasket is sealingly arranged on the inner ring of the melt cavity.

[0009] Furthermore, the distribution holes on the distribution plate are in a gradually shrinking structure from the melt input end to the melt output end.

[0010] Furthermore, the distribution holes are arranged parallel to the axis of the distribution plate, and the spinneret holes are arranged parallel to the axis of the spinneret plate.

[0011] Beneficial effects: The utility model assembles the distribution plate and the spinneret shaft via a plate center connector. In the axial direction, a pulling force is exerted on the spinneret in the opposite direction to the deformation trend. The pulling force can prevent the spinneret from being deformed by high pressure and high temperature conditions, thereby preventing leakage and pressure relief caused by structural deformation, ensuring sealing and improving the quality of the yarn, and is suitable for large-scale promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Attached Figure 1 It is a schematic diagram of the overall structure of the utility model;

[0013] Attached Figure 2 It is a schematic diagram of the structure decomposition of the utility model;

[0014] Attached Figure 3 It is a schematic diagram of the half-section structure of the utility model. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings.

[0016] As attached Figure 1 , Attachment Figure 2 And attached Figure 3 As shown, the distribution plate and spinneret assembly structure for industrial spinning includes a distribution plate 1 with a distribution hole 10 and a spinneret 2 with a spinneret hole 20. The distribution hole 10 and the spinneret 2 are coaxially sealed and spliced to form a melt cavity 6 that connects the distribution hole 10 to the spinneret hole 20; it is characterized in that: it also includes a plate center connector 3, and a seal is provided at the splicing of the distribution plate 1 and the spinneret 2. The distribution plate 1 and the spinneret 2 are connected by the plate center connector 3 and are axially displaced toward each other to squeeze the seal to seal the melt cavity 6. The utility model axially assembles the distribution plate 1 and the spinneret 2 through the plate center connector 3. In the axial direction, the spinneret 2 has a pulling force opposite to the deformation trend. Through the pulling of the pulling force, the spinneret can be prevented from being deformed by the high pressure and high temperature working conditions, thereby avoiding leakage and pressure relief caused by structural deformation, ensuring sealing and improving the quality of the formed silk.

[0017] As attached Figure 3As shown, the connection position of the plate center connector 3 is located at the center of the distribution plate 1 and the spinneret 2. If the spinneret 2 is deformed, its deformation state is generally an axial convex curved surface structure from the center to the outside, which is relatively symmetrical. The connection position of the plate center connector 3 is exactly located at the center of the plate. This connection point position has the best effect of limiting the structural deformation of the spinneret 2.

[0018] As attached Figure 2 and attached Figure 3 As shown, the plate center connector 3 includes a threaded rod 31, a column rod 32 and a hexagonal mounting head 33 connected in sequence; a column hole 11 is provided at the center of the distribution plate 1, and a threaded hole 21 is provided at the center of the spinneret 2. The threaded rod 31 passes through the column hole 11 and is screwed into the threaded hole 21, and the column rod 32 is inserted into the column hole 11; the plate center connector 3 is threadedly rotated relative to the spinneret 2 to make the distribution plate 1 and the spinneret 2 move toward each other to achieve splicing and fixation. The greater the rotation stroke of the plate center connector 3, the better the tightness of the connection between the distribution plate 1 and the spinneret 2. However, affected by the extreme physical characteristics of the structural deformation of the seal, the rotation stroke of the plate center connector 3 should be controlled to keep the seal within the physical deformation range of the effective sealing characteristics.

[0019] More specifically, a mounting head hole 12 which is concentrically connected to the column hole 11 is also provided at the center of the distribution plate 1, and the hexagonal mounting head 33 is hidden in the mounting head hole 12, so as to reduce space occupation and reserve space for subsequent assembly of other structures of the spinning assembly.

[0020] As attached Figure 2 and attached Figure 3 As shown, the sealing member includes an outer sealing gasket 4 and an inner sealing gasket 5 . The outer sealing gasket 4 is sealingly arranged on the outer ring of the melt cavity 6 , and the inner sealing gasket 5 is sealingly arranged on the inner ring of the melt cavity 6 .

[0021] In order to make the melt flow smoother, the distribution hole 10 is arranged parallel to the axis of the distribution plate 1, and the spinneret hole 20 is arranged parallel to the axis of the spinneret 2. It is worth noting that the distribution hole 10 on the distribution plate 1 is in a gradually shrinking structure from the melt input end to the melt output end, so that the melt can more easily enter the melt cavity 6 and be distributed to each spinneret hole 20.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
