Description

Technical Field

[0001] The utility model relates to a special-shaped spinneret, belonging to the technical field of spinnerets. Background Art

[0002] The spinneret is also called the spinning cap. The function of the spinneret is to transform the viscous polymer melt or solution into a thin flow with a specific cross-section through micropores, and solidify it into filaments through a coagulation medium such as air or a coagulation bath.

[0003] The spinneret holes on the surface of the spinneret are fixed, and the spinneret may need to spray out filaments of various shapes during use. Therefore, when filaments of different shapes need to be sprayed out, the spinneret needs to be disassembled and replaced. At the same time, after long-term use, the nozzle position of the spinneret is more susceptible to interference from dust or other factors and becomes clogged. At this time, the spinneret also needs to be disassembled and cleaned. The spinneret is usually fixed to the nozzle of the spinneret by welding. It is cumbersome to disassemble it, which is inconvenient for people to use.

[0004] Therefore, a special-shaped spinneret is proposed. Utility Model Content

[0005] In view of this, the utility model provides a special-shaped spinneret to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0006] The technical solution of the utility model is implemented as follows: a special-shaped spinneret, comprising a main plate and a sub-plate, the front side of the main plate is provided with a circular groove, the sub-plate is arranged in the inner cavity of the circular groove, the front side of the sub-plate is provided with spinneret holes, the surface of the sub-plate is provided with jacks around, the surface of the sub-plate is provided with card slots around, and the rear side of the main plate is fixedly provided with a feed port;

[0007] A disassembly mechanism is provided on the front side of the main board, and the disassembly mechanism includes a cavity, four of the cavities are opened in the inner surface of the main board, sliding rods are fixedly installed on the outer sides of the four cavities, and slides are slidably connected on the surfaces of the eight sliding rods, hard springs are fixedly installed on the left and right sides of the outer sides of the four slides, plug blocks are fixedly installed on the inner sides of the four slides, connecting blocks are fixedly installed on the front sides of the four slides, mounting plates are fixedly installed on the front sides of the four connecting blocks, and fixing bolts are threadedly connected on the surfaces of the four mounting plates.

[0008] Further preferably, screw grooves are provided around the front side of the main board, and the rear sides of the eight fixing bolts are threadedly connected to the inner cavities of the eight screw grooves.

[0009] Further preferably, sliding grooves are provided on the outer sides of the inner cavities of the four cavities, and the outer sides of the four slide plates are slidably connected to the inner cavities of the eight sliding grooves.

[0010] Further preferably, slots are provided on the inner sides of the inner cavities of the four cavities, and the four plug blocks penetrate the inner cavities of the four slots and are plugged into the inner cavities of the four jacks.

[0011] Further preferably, movable grooves are provided around the front side of the main board, and the four connecting blocks penetrate the inner cavities of the four movable grooves and extend to the front side of the main board.

[0012] Further preferably, the four slots and the four jacks are in the same vertical and horizontal directions, and the four slots and the four jacks are interconnected.

[0013] Further preferably, clamping blocks are fixedly installed around the inner cavity of the circular groove, and the four clamping blocks are clamped in the inner cavities of the four clamping slots.

[0014] Further preferably, a sealing ring is fixedly mounted on the rear side of the main board, and the inner side of the sealing ring fits with the outer side of the feed port.

[0015] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0016] 1. The utility model provides a disassembly mechanism. When it is necessary to spray out wire strips of different shapes or the spinneret hole is clogged and needs to be cleaned, the fixing bolt is screwed to release the limit on the mounting plate, and then the connecting block and the mounting plate are pulled to move outward. As the connecting block moves, the slide plate drives the plug-in block to move outward synchronously, and the plug-in block is moved out of the inner cavity of the plug hole. At this time, the hard spring is deformed due to the action of the force, and then the sub-plate is pulled to the front side to complete the disassembly of the sub-plate, which is convenient for replacing the sub-plate of the spinneret hole of different shapes, and also convenient for cleaning the clogged spinneret hole. The disassembly method is relatively convenient, which improves the convenience of disassembly of the spinneret part and is convenient for people to use.

[0017] Second, the utility model can limit the mounting plate by setting the screw groove, so as to avoid the shaking of the mounting plate due to interference from external factors, causing the plug block to move out of the inner cavity of the socket, so as to reduce the tightness of the sub-plate fixation. By setting the sliding groove, the moving direction of the slide plate can be limited, so as to avoid the displacement caused by the movement of the slide plate, which in turn affects the removal or installation of the sub-plate. By setting the slot, the moving direction of the connecting block can be limited, so as to avoid the problem that the direction of the connecting block changes when it moves, and the connection block cannot be inserted into the inner cavity of the socket or cannot be removed from the inner cavity of the socket. By setting the moving groove, the moving direction of the connecting block can be limited, so as to avoid the problem that the connection block cannot be inserted into the inner cavity of the socket or cannot be removed from the inner cavity of the socket when pulling the connection. When the block moves, the direction of the connecting block shifts, thereby affecting the fixing effect of the plug-in block on the sub-plate. By setting the slot and the socket, since the two are in the same horizontal and vertical directions, the plug-in block can pass freely when moving inward, and will not be unable to fix the sub-plate due to obstruction of other objects. By setting the card block, the position of the card slot can be limited so that the positions of the slot and the socket are at the same angle, which is convenient for the plug-in block to be inserted into the socket along the inner cavity of the slot, thereby improving the convenience of installing or removing the sub-plate. By setting the sealing ring, a sealing effect can be achieved to avoid leakage from the connection between the feed port and the sub-plate when the spinneret sprays out the material, thereby preventing the waste of material.

DETAILED DESCRIPTION

[0026] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5 As shown, the embodiment of the utility model provides a special-shaped spinneret, including a main plate 1 and a sub-plate 3, a circular groove 7 is provided on the front side of the main plate 1, the sub-plate 3 is arranged in the inner cavity of the circular groove 7, a spinneret hole 4 is provided on the front side of the sub-plate 3, a plug hole 6 is provided on the surface of the sub-plate 3, a card slot 5 is provided on the surface of the sub-plate 3, and a feed port 8 is fixedly installed on the rear side of the main plate 1;

[0030] A disassembly mechanism 2 is provided on the front side of the mainboard 1, and the disassembly mechanism 2 includes a cavity 201. Four cavities 201 are opened in the inner surface of the mainboard 1. Slide rods 202 are fixedly installed on the outer sides of the inner cavities of the four cavities 201. Slide plates 203 are slidably connected to the surfaces of the eight slide rods 202. Hard springs 204 are fixedly installed on the left and right sides of the outer sides of the four slide plates 203. Insert blocks 205 are fixedly installed on the inner sides of the four slide plates 203. Connecting blocks 206 are fixedly installed on the front sides of the four slide plates 203. Mounting plates 207 are fixedly installed on the front sides of the four connecting blocks 206. Fixing bolts 208 are threadedly connected to the surfaces of the four mounting plates 207.

[0031] By setting up the disassembly mechanism 2, when it is necessary to spray out wire strips of different shapes or the spinneret hole 4 is clogged and needs to be cleaned, the fixing bolt 208 is screwed to release the limit on the mounting plate 207, and then the connecting block 206 and the mounting plate 207 are pulled to move outward. As the connecting block 206 moves, the slide plate 203 drives the plug block 205 to move outward synchronously, and the plug block 205 is moved out of the inner cavity of the socket 6. At this time, the hard spring 204 is deformed due to the action of the force, and then the sub-plate 3 is pulled to the front side, so that the disassembly of the sub-plate 3 can be completed, which is convenient for replacing the sub-plate 3 of the spinneret hole 4 of different shapes, and it is also convenient for cleaning the clogged spinneret hole 4. The disassembly method is relatively convenient, which improves the convenience of disassembly of the spinneret part and is convenient for people to use.

[0032] Example 2

[0033] In one embodiment, screw grooves 209 are provided around the front side of the main board 1, and the rear sides of the eight fixing bolts 208 are threadedly connected to the inner cavities of the eight screw grooves 209. The outer sides of the inner cavities of the four cavities 201 are provided with sliding grooves 210. The outer sides of the four slide plates 203 are slidably connected to the inner cavities of the eight sliding grooves 210. The inner sides of the inner cavities of the four cavities 201 are provided with slots 211. The four plug blocks 205 penetrate the inner cavities of the four slots 211 and are plugged into the inner cavities of the four jacks 6. Movable grooves 212 are provided on all sides of the side, four connecting blocks 206 penetrate the inner cavities of the four movable grooves 212 and extend to the front side of the main board 1, the four slots 211 and the four jacks 6 are in the same vertical and horizontal directions, the four slots 211 and the four jacks 6 are interconnected, and card blocks 10 are fixedly installed on all sides of the inner cavity of the circular groove 7, and the four card blocks 10 are snapped into the inner cavities of the four card slots 5, and a sealing ring 9 is fixedly installed on the rear side of the main board 1, and the inner side of the sealing ring 9 fits with the outer side of the feed port 8.

[0034] By providing the screw groove 209, the fixing bolt 208 can be conveniently used to limit the mounting plate 207, so as to avoid the mounting plate 207 from shaking due to interference from external factors, causing the plug block 205 to move out of the inner cavity of the socket 6, resulting in a decrease in the tightness of the fixing of the sub-plate 3. By providing the sliding groove 210, the moving direction of the slide plate 203 can be limited, so as to avoid the displacement of the slide plate 203 when moving, thereby affecting the disassembly or installation of the sub-plate 3. By providing the slot 211, the moving direction of the connecting block 206 can be limited, so as to avoid the problem that the connecting block 206 changes direction when moving, cannot be inserted into the inner cavity of the socket 6 or cannot be moved out of the inner cavity of the socket 6. By providing the moving groove 212, the moving direction of the connecting block 206 can be limited, so as to avoid the problem that the connecting block 206 cannot be inserted into the inner cavity of the socket 6 or cannot be moved out of the inner cavity of the socket 6 when pulling the connecting block 203. When the connecting block 206 moves, the direction of the connecting block 206 is offset, thereby affecting the fixing effect of the plug block 205 on the sub-plate 3. By setting the slot 211 and the socket 6, since the two are in the same horizontal and vertical directions, the plug block 205 can pass freely when moving inward, and will not be unable to fix the sub-plate 3 due to obstruction of other objects. By setting the card block 10, the position of the card slot 5 can be limited, so that the slot 211 and the socket 6 are at the same angle, which is convenient for the plug block 205 to be inserted into the socket 6 along the inner cavity of the slot 211, thereby improving the convenience of installing or removing the sub-plate 3. By setting the sealing ring 9, a sealing effect can be achieved to avoid leakage from the connection between the feed port 8 and the sub-plate 3 when the spinneret sprays out the material, thereby preventing the waste of material.

[0035] The utility model is in operation: when the auxiliary plate 3 needs to be replaced or cleaned, the fixing bolt 208 is screwed to remove it from the inner cavity of the screw groove 209, and the mounting plate 207 is grasped and moved outward. At this time, the connecting block 206 drives the slide plate 203 to move outward synchronously. As the slide plate 203 moves, the plug block 205 moves outward along the inner cavity of the slot 211 and moves out of the inner cavity of the socket 6. At this time, the hard spring 204 is deformed due to the squeezing of the slide plate 203, and then the auxiliary plate 3 is pulled to move to the front side, completing the disassembly of the auxiliary plate 3. When the auxiliary plate 3 is cleaned or replaced, After the replacement, the sub-plate 3 is again engaged in the inner cavity of the circular groove 7 through the cooperation of the clamping block 10 and the clamping slot 5, and then the mounting plate 207 is loosened. At this time, the hard spring 204 loses its force and deforms again, and at the same time, its own tension pushes the slide plate 203 to move inward. At this time, the slide plate 203 drives the plug block 205, the connecting block 206 and the mounting plate 207 to move inward synchronously, and the plug block 205 is inserted into the inner cavity of the socket 6 along the inner cavity of the slot 211, and then the fixing bolt 208 is screwed again to make it threadedly connected to the inner cavity of the screw groove 209, thereby completing the installation of the sub-plate 3.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
