Description

Technical Field

[0001] The present application relates to the technical field of spinning production, and in particular to a feeding structure for spinning production. Background Art

[0002] Spinning, also known as chemical fiber forming, is a process in the manufacture of chemical fibers. It involves forming a colloidal solution or a melt of certain polymer compounds, which is then extruded through the fine holes of a spinneret to form chemical fibers.

[0003] The process flows of existing spinning production equipment are generally similar. Chinese Patent Publication No. CN210237857U discloses a production device for nylon 6 mother yarn fibers. The device comprises a feed unit, a screw extruder, a spinning assembly, an annealer, a monomer extraction device, a side-blowing device, a tunnel, an oiling device, a drafting assembly, and a winder, arranged in the order of the process flow.

[0004] Among them, the feeding unit includes a main silo, a masterbatch silo and a masterbatch meter, wherein the main silo and the masterbatch silo are arranged in parallel, the main silo is used to store nylon dry chips, and the output end of the main silo is connected to the screw extruder to transport the nylon dry chips to the screw extruder, and the masterbatch silo is used to store nylon color masterbatch, and its input end is connected to the screw extruder through the masterbatch meter to transport the nylon 6 color masterbatch to the screw extruder.

[0005] Since the amount of dry chips required in the spinning production process is greater than the amount of masterbatch required, the diameter of the main pipeline used to transport the dry chips will be larger than the diameter of the secondary pipeline used to transport the masterbatch, and the discharge port end of the secondary pipeline is connected and communicated with the discharge port end of the main pipeline, so that the dry chips and masterbatch can enter the mixing pipeline for continued transportation.

[0006] However, when the dry chips are fed through the main pipeline, since the discharge port end of the secondary pipeline is close to the discharge port end of the main pipeline, it is easy for the discharge port of the secondary pipeline to be blocked, thereby affecting the discharge of the masterbatch from the secondary pipeline, and also affecting the speed at which the dry chips are fed through the main pipeline. Summary of the Invention

[0007] In order to improve the problem that dry chips are easily blocked at the outlet of the secondary pipeline, which affects the feeding of both the main pipeline and the secondary pipeline, the present application provides a feeding structure for spinning production.

[0008] The present application provides a feeding structure for spinning production, which adopts the following technical solution:

[0009] A feeding structure for spinning production includes a main pipeline, a secondary pipeline and a mixing pipeline. The discharge port end of the main pipeline and the discharge port end of the secondary pipeline are both connected to the feed pipe end of the mixing pipeline, and the discharge port end of the secondary pipeline extends into the mixing pipeline. It also includes a discharge hopper, which is located inside the mixing pipeline and is connected to the end of the secondary pipeline; the discharge hopper is expanded in the direction away from the secondary pipeline, and the end of the discharge hopper close to the discharge port of the main pipeline is the expanded end; there is a gap between the discharge hopper and the inner wall of the mixing pipeline for dry slices to pass through.

[0010] By adopting the above technical solution, in the process of feeding the dry slices from the main pipe into the mixing pipe, the outer surface of the discharge hopper can guide the dry slices, so that the dry slices can continue to move around the discharge port of the auxiliary pipe; at the same time, in the process of feeding the masterbatch from the auxiliary pipe into the mixing pipe, the masterbatch will move under the guidance of the inner surface of the discharge hopper, so that the discharge is more uniform, and the discharge hopper can temporarily separate the masterbatch and the dry slices, thereby reducing the probability of blockage caused by the dry slices and the masterbatch merging at the feed port of the mixing pipe and then entering the mixing pipe, thereby enabling the feeding structure to feed stably, ensuring that the spinning production can proceed smoothly and orderly.

[0011] Optionally, the discharge hopper is movably connected to the secondary pipeline, and the dry slices push the discharge hopper to move after entering the mixing pipeline from the main pipeline.

[0012] By adopting the above technical solution, in the process of feeding the dry slices from the main pipeline into the mixing pipeline, the dry slices can push the discharge hopper to move relative to the auxiliary pipeline. After the discharge hopper moves, the space in the mixing pipeline for the dry slices to pass through is expanded accordingly, which can facilitate the dry slices to pass through the space between the discharge hopper and the inner wall of the mixing pipeline, thereby reducing the probability of dry slices being blocked in the mixing pipeline; at the same time, after the discharge hopper moves relative to the auxiliary pipeline, the discharge position of the masterbatch in the mixing pipeline is also changed under the guidance of the discharge hopper, thereby reducing the probability of masterbatch and dry slices being blocked after merging in the mixing pipeline.

[0013] Optionally, the discharge hopper is rotatably connected to the secondary pipeline, and the rotation axis of the discharge hopper is horizontal and perpendicular to the feeding direction of the main pipeline.

[0014] By adopting the above technical solution, the rotation direction of the discharge hopper relative to the auxiliary pipeline is limited, the rotation freedom of the discharge hopper part is reduced, and the stability of the discharge hopper during rotation is improved; in the process of feeding the dry slices through the main pipeline, the dry slices are mainly concentrated in the position near the bottom of the main pipeline for movement, so after limiting the rotation direction of the discharge hopper, it can further facilitate the dry slices to push the discharge hopper to rotate, and at the same time ensure that the dry slices can pass through conveniently after the discharge hopper rotates.

[0015] Optionally, it also includes a plurality of guide bars, which are distributed in a circular array around the circumference of the discharge hopper with the axis of the discharge hopper as the axis; channels for the dry slices to pass through are formed between adjacent guide bars, and there is a distance between the guide bars and the inner wall of the mixing pipe.

[0016] By adopting the above technical solution, in the process of feeding the dry slices from the main pipeline into the mixing pipeline, the outer surface of the discharge hopper guides the dry slices, and a plurality of guide strips can further guide the dry slices; the channel formed between adjacent guide strips can guide the dry slices to pass through in an orderly manner, thereby effectively avoiding the probability of a large number of dry slices passing through the space between the discharge hopper and the inner wall of the mixing pipeline and causing blockage; and there is always an air-permeable space between the guide strips and the inner wall of the mixing pipeline, thereby reducing the probability of dry slices forming a blockage in the channel.

[0017] Optionally, it also includes a rotating sleeve, which is arranged on the discharging hopper, the rotating sleeve is rotatably connected to the discharging hopper, and the rotation axis of the rotating sleeve coincides with the axis of the discharging hopper; a plurality of guide bars are arranged on the side of the rotating sleeve away from the discharging hopper, and one side of the guide bar has a first driving surface, and the first driving surface drives the rotating sleeve to rotate after being subjected to force.

[0018] By adopting the above technical solution, when the dry slice passes through the channel under the guidance of the guide bar, the dry slice will exert a force on the first driving surface, thereby driving the rotating sleeve to rotate relative to the discharge hopper. The rotating rotating sleeve can increase the activity intensity of the dry slice when passing between the discharge hopper and the inner wall of the mixing pipe, thereby further reducing the probability of the dry slice forming a blockage between the discharge hopper and the inner wall of the mixing pipe; at the same time, when the dry slice is blocked in part of the channel, the rotation of the rotating sleeve can clear the blockage in the channel.

[0019] Optionally, it also includes a plurality of vibration components, which are arranged on the rotating sleeve. The vibration components include an impact member and an elastic member. The impact member is slidably connected to the rotating sleeve. The elastic member drives the impact member to slide toward the direction close to the discharge hopper, and the discharge hopper is provided with a plurality of impact grooves adapted to the impact member.

[0020] By adopting the above technical solution, during the rotation of the rotating sleeve relative to the discharge hopper, the impact member will move in and out of different impact grooves through the characteristic that the elastic member can freely expand and contract and deform. When the impact member enters the impact groove under the action of the elastic member, the impact member will collide with the groove wall of the impact groove, thereby causing the discharge hopper to vibrate, and the discharge hopper can transmit the vibration to the auxiliary pipeline, thereby reducing the probability of the masterbatch forming a blockage at the discharge port of the auxiliary pipeline, and at the same time, it can play a role in clearing the blockage when the masterbatch forms a blockage at the discharge port of the auxiliary pipeline.

[0021] Optionally, one end of the rotating sleeve is close to the secondary pipe, and the vibration component is located at the end of the rotating sleeve close to the secondary pipe.

[0022] By adopting the above technical solution, the vibration effects of several vibration components on the discharge hopper can be concentrated at the position of the discharge hopper close to the auxiliary pipeline, thereby improving the vibration effect transmitted from the discharge hopper to the auxiliary pipeline, and further improving the effect of reducing the probability of masterbatch blocking the discharge port of the auxiliary pipeline through vibration.

[0023] Optionally, a plurality of material blocking members are further included, and the plurality of material blocking members are located in the mixing pipe and close to the discharge port of the secondary pipe.

[0024] By adopting the above technical solution, when the masterbatch passes through the discharge hopper, the blocking member can block part of the masterbatch, and the direction of the masterbatch leaving the discharge hopper blocked by the blocking member will change, so that the direction of the masterbatch leaving the discharge hopper can be more dispersed, and the discharge of the masterbatch can be more uniform, thereby further reducing the probability of blockage caused by the masterbatch and dry chips merging in the main pipeline.

[0025] Optionally, one end of each of the plurality of material blocking members is connected to the rotating sleeve, and the rotation of the rotating sleeve drives the plurality of material blocking members to rotate about the rotation axis of the rotating sleeve.

[0026] By adopting the above technical solution, when the rotating sleeve rotates and drives several blocking members to rotate, the blocking members in the rotating state can increase the probability of themselves contacting the masterbatch, thereby improving the blocking effect of the blocking members on the masterbatch, and then improving the dispersion degree of the masterbatch after leaving the discharge hopper, further making the discharge of the masterbatch more uniform.

[0027] Optionally, the material blocking member has a second driving surface at one end close to the secondary pipe, and the second driving surface drives the rotating sleeve to rotate when subjected to force, and the direction in which the rotating sleeve is driven to rotate when the second driving surface is subjected to force is opposite to the direction in which the rotating sleeve is driven to rotate when the first driving surface is subjected to force.

[0028] By adopting the above technical solution, after the masterbatch contacts the material blocking member, it will apply a force to the second driving surface, thereby driving the material blocking member to drive the rotating sleeve to rotate; when the dry slices form a blockage between the discharge hopper and the inner wall of the mixing pipe, causing the rotating sleeve to be unable to rotate, after the masterbatch contacts the material blocking member, the force applied by the masterbatch to the second driving surface will cause the rotating sleeve to rotate slightly, and the rotating sleeve drives a number of guide bars to rotate. During the rotation of the guide bars, the dry slices that form the blockage will be driven to move in the direction away from the flared end of the discharge hopper and then pass through the channel again, thereby achieving the effect of clearing the blockage, and the clearing effect is better than the clearing effect when the first driving surface is subjected to force to drive the rotating sleeve to rotate.

[0029] In summary, this application has at least one of the following beneficial effects:

[0030] 1. It can reduce the probability of blockage caused by the simultaneous feeding of dry chips and masterbatch into the mixing pipe, which leads to the collection of dry chips and masterbatch at the outlet of the auxiliary pipe. This enables the feeding structure to feed materials stably and ensures that the spinning production can proceed smoothly and orderly.

[0031] 2. The discharge hopper can change its position in the mixing pipe according to the amount of dry chips fed, so that the dry chips can pass smoothly and reduce the probability of dry chips forming a blockage between the discharge hopper and the inner wall of the mixing pipe;

[0032] 3. The discharge hopper can guide the dry slices to pass smoothly and orderly, and when the dry slices pass between the discharge hopper and the inner wall of the mixing pipe, they can drive the rotating sleeve to rotate. The rotation of the rotating sleeve can reduce the probability of dry slice blockage and clear the blockage of dry slices.

[0033] 4. It can disperse and evenly distribute the masterbatch into the main pipe through the auxiliary pipe and the discharge hopper, thereby further reducing the probability of blockage caused by the combination of dry chips and masterbatch;

[0034] 5. When the dry chips form a blockage between the discharge hopper and the inner wall of the mixing pipe, the masterbatch contacts the material blocking piece and can clear the blockage of the dry chips; when the masterbatch forms a blockage at the discharge port of the auxiliary pipe, the dry chips drive the rotating sleeve to rotate and the vibration component can make the auxiliary pipe vibrate, thereby clearing the blockage.

[0042] The following is combined with Figure 1-6 This application is described in further detail.

[0043] Reference Figure 1 The embodiment of the present application discloses a feeding structure for spinning production, including a main pipe 1, a sub-pipe 2 and a mixing pipe 3. The main pipe 1 is used to transport dry chips, the sub-pipe 2 is used to transport masterbatch, and the mixing pipe 3 is used to mix the dry chips and masterbatch and then continue to transport them. Preferably, the main pipe 1, the sub-pipe 2 and the mixing pipe 3 are all circular pipes, and the diameters of the mixing pipe 3, the main pipe 1 and the sub-pipe 2 decrease in sequence. The end of the sub-pipe 2 close to its own discharge port is fixedly connected to and communicates with the main pipe 1, the discharge port end of the main pipe 1 is fixedly connected to the feed port end of the mixing pipe 3, the main pipe 1 and the sub-pipe 2 are both in communication with the mixing pipe 3, and the discharge port end of the sub-pipe 2 passes through the interior of the main pipe 1 and is located inside the mixing pipe 3 near its own feed port.

[0044] The discharge port end of the main pipeline 1 and the feed port end of the mixing pipeline 3 are fixedly connected with a connecting seat 4 for facilitating the fixed connection between the two. Preferably, the connecting seat 4 is an annular structure (similar to a flange), and preferably, the connecting seat 4 and the main pipeline 1 and the mixing pipeline 3 are fixedly connected by welding, and preferably, the connecting seat 4 of the main pipeline 1 and the connecting seat 4 of the mixing pipeline 3 are fixedly connected by a plurality of bolts and a plurality of nuts.

[0045] The main pipe 1 and the mixing pipe 3 are both installed and fixed in a state where the plane where the connecting seat 4 is located is horizontal. In this embodiment, the main pipe 1 is preferably inclined relative to the plane where its own connecting seat 4 is located, and accordingly, the secondary pipe 2 is perpendicular to the plane where the connecting seat 4 on the main pipe 1 is located, that is, the axis of the main pipe 1 is inclined to the axis of the connecting seat 4, and the axis of the secondary pipe 2 is parallel to the axis of the connecting seat 4; preferably, the mixing pipe 3 is perpendicular to the plane where its own connecting seat 4 is located, and the axis of the mixing pipe 3 coincides with the axis of the mounting seat; after the main pipe 1 and the mixing pipe 3 are fixedly connected, the axis of the secondary pipe 2 is parallel to the axis of the mixing pipe 3.

[0046] Reference Figure 2 and Figure 3 The feeding structure further includes a discharge hopper 5, preferably a funnel-shaped structure. The discharge hopper 5 is located inside the mixing pipe 3, and the constricted end of the discharge hopper 5 is movably connected to the end of the auxiliary pipe 2 near its own discharge port. Preferably, the end of the auxiliary pipe 2 near its own discharge port is a spherical structure with an opening. The constricted end of the discharge hopper 5 is adapted to the spherical cut of the auxiliary pipe 2, and the constricted end of the discharge hopper 5 is sleeved on the spherical structure of the auxiliary pipe 2, so that the connection between the discharge hopper 5 and the auxiliary pipe 2 is similar to a ball hinge.

[0047] When the discharge hopper 5 is not affected by any external force except its own gravity, the axis of the discharge hopper 5 will coincide with the axis of the auxiliary pipe 2; when the discharge hopper 5 is affected by other external forces in addition to its own gravity, the movement of the discharge hopper 5 relative to the auxiliary pipe 2 is restricted. During the movement of the discharge hopper 5, a certain distance is always maintained between the discharge hopper 5 and the inner wall of the mixing pipe 3.

[0048] When the dry slices are fed through the main pipe 1, when the dry slices move and pass between the discharge hopper 5 and the inner wall of the mixing pipe 3, the dry slices can push the discharge hopper 5 to move relative to the auxiliary pipe 2, so that the space between the discharge hopper 5 and the inner wall of the mixing pipe 3 is expanded to facilitate the passage of the dry slices; when the masterbatch is fed through the auxiliary pipe 2, after the masterbatch enters the discharge hopper 5 from the auxiliary pipe 2, the inner surface of the discharge hopper 5 has a guiding effect on the masterbatch, and can guide the masterbatch to leave the discharge hopper 5 and enter the main pipe 1 to merge with the dry slices, and when the discharge hopper 5 moves relative to the auxiliary pipe 2, the position where the discharge hopper 5 guides the masterbatch to enter the mixing pipe 3 and merge with the dry slices also changes.

[0049] Furthermore, since the dry slices are mainly transported at a position near the bottom of the main pipe 1 during feeding through the main pipe 1, after the dry slices enter the mixing pipe 3 from the main pipe 1, the dry slices are mainly in contact with the position of the discharge hopper 5 near the main pipe 1. At this time, when the dry slices move and push the discharge hopper 5 to move relative to the secondary pipe 2, if the discharge hopper 5 rotates relative to the secondary pipe 2 with the direction parallel to and perpendicular to the feeding direction of the main pipe 1 as the axis, then in this case, the space provided by the discharge hopper 5 after the position change for the dry slices to pass through is the largest, that is, this is the most favorable situation.

[0050] Therefore, the degree of freedom of movement of the discharge hopper 5 relative to the auxiliary pipe 2 is further limited. Preferably, the discharge hopper 5 and the auxiliary pipe 2 are connected in a rotational manner, with the rotation axis of the discharge hopper 5 being horizontal and perpendicular to the feeding direction of the main pipe 1. Since it is a common technical method to change the ball joint to a rotational connection, it will not be described in detail here, and the relevant specific structure is not shown in the drawings.

[0051] The feeding structure also includes a rotating sleeve 6 and a plurality of guide bars 7. The rotating sleeve 6 is a truncated cone-shaped sleeve structure. The rotating sleeve 6 is sleeved on the discharge hopper 5. The rotating sleeve 6 is rotatably connected to the discharge hopper 5, and the rotation axis of the rotating sleeve 6 coincides with the axis of the discharge hopper 5. The guide bar 7 is a strip-shaped structure as a whole. The guide bar 7 is fixedly installed on the side of the rotating sleeve 6 away from the discharge hopper 5. The length direction of the guide bar 7 is parallel to the busbar corresponding to its position on the rotating sleeve 6, and the plurality of guide bars 7 are distributed in a circular array with the axis of the rotating sleeve 6 as the axis.

[0052] A channel 10 for the dry slices to pass through is formed between two adjacent guide bars 7. When the discharge hopper 5 rotates to the extreme position toward the inner wall of the mixing pipe 3, there is a gap between the guide bar 7 and the inner wall of the mixing pipe 3. At this time, the space formed between the guide bar 7 and the inner wall of the mixing pipe 3 cannot allow the dry slices to pass through. The dry slices can pass between the two guide bars 7, that is, through the channel 10.

[0053] The guide bars 7 have one end surface parallel to the corresponding generatrix of their position on the rotating sleeve 6, and the other side has a first drive surface 71. The spacing between the end surfaces of the guide bars 7 gradually increases along the axis of the rotating sleeve 6 toward the direction of expansion of the rotating sleeve 6. When the dry slice enters between the two guide bars 7 and contacts the first drive surface 71 during movement, the dry slice will apply a force to the first drive surface 71, driving the rotating sleeve 6 to rotate relative to the discharge hopper 5.

[0054] Reference Figure 3 and Figure 4Furthermore, the feeding structure also includes a plurality of vibration components 8, which are all installed on the rotating sleeve 6, and the plurality of vibration components 8 are distributed in a circular array with the axis of the rotating sleeve 6 as the axis. The vibration component 8 includes an impact member 81 and an elastic member 82. The impact member 81 is slidably connected to the rotating sleeve 6. Preferably, the sliding direction of the impact member 81 is perpendicular to the busbar corresponding to its position on the rotating sleeve 6. The impact member 81 has a limit in the process of sliding relative to the rotating sleeve 6. When the impact member 81 slides to the extreme position in the direction away from the discharge hopper 5, the impact member 81 slides back to the inside of the rotating sleeve 6; when the impact member 81 slides to the extreme position in the direction close to the discharge hopper 5, the impact member 81 partially passes through the rotating sleeve 6. Correspondingly, the surface of the discharge hopper 5 is provided with a plurality of impact grooves 51 that are compatible with the protruding parts of the impact member 81.

[0055] The elastic member 82 is installed inside the rotating sleeve 6, and the elastic member 82 is located on the side of the impact member 81 away from the discharge hopper 5. Preferably, the elastic member 82 is a compression spring, and the two ends of the elastic member 82 are respectively in contact with the rotating sleeve 6 and the impact member 81, and the elastic member 82 drives the impact member 81 to slide toward the direction close to the discharge hopper 5.

[0056] The number of impact slots 51 defined in the discharge hopper 5 is preferably greater than the number of vibration assemblies 8 mounted on the rotating sleeve 6, and the number of impact slots 51 is an integer multiple of the number of vibration assemblies 8. During the rotation of the rotating sleeve 6 relative to the discharge hopper 5, when the sliding direction of the impact member 81 is not aligned with the impact slot 51, the impact member 81 will remain in contact with the surface of the discharge hopper 5 under the force of the elastic member 82. When the sliding direction of the impact member 81 is aligned with the impact slot 51, the impact member 81 will slide into the impact slot 51 under the force of the elastic member 82, impacting the discharge hopper 5 and causing the discharge hopper 5 to vibrate. Furthermore, during the rotation of the rotating sleeve 6 relative to the discharge hopper 5, the sliding of the multiple impact members 81 is synchronized.

[0057] Furthermore, after the rotating sleeve 6 is preferably installed on the discharge hopper 5, the necked end of the rotating sleeve 6 is close to the necked end of the discharge hopper 5, and a number of vibration components 8 are installed at a position close to the necked end of the rotating sleeve 6 itself, so that the position where the vibration of the several vibration components 8 on the discharge hopper 5 is concentrated is closer to the auxiliary pipe 2, thereby improving the effect of vibration on preventing and clearing blockages in the auxiliary pipe 2.

[0058] Back to Figure 2 and Figure 3Furthermore, the feeding structure further includes a plurality of blocking members 9, which are preferably fixedly connected to the discharge hopper 5, and are all located inside the discharge hopper 5. After the masterbatch enters the discharge hopper 5 from the auxiliary pipe 2, some of the masterbatch will come into contact with the blocking members 9, which will change the feeding direction of the masterbatch after contact with it, thereby effectively preventing the masterbatch from being concentrated and merging with the dry slices when leaving the discharge hopper 5, thereby making the masterbatch discharge more evenly dispersed.

[0059] In order to improve the overall structural stability of the plurality of material blocking members 9 , it is preferred that one end of the material blocking member 9 is fixedly connected to the inner side of the discharge hopper 5 , and the other end of the material blocking member 9 is fixedly connected to the end of the other material blocking members 9 .

[0060] Reference Figure 5 and Figure 6 Furthermore, preferably, one end of the material stopper 9 is fixedly connected to the end of the rotating sleeve 6 away from the auxiliary pipe 2, and the other end of the material stopper 9 is also fixedly connected to the end of the other material stopper 9. Several material stoppers 9 are located on the side of the discharge hopper 5 away from the auxiliary pipe 2 and close to the discharge port of the discharge hopper 5, and the several material stoppers 9 are distributed in a circular array with the axis of the rotating sleeve 6 as the axis.

[0061] When the rotating sleeve 6 rotates, it will drive several blocking members 9 to rotate synchronously with the rotating axis of the rotating sleeve 6 as the axis, thereby increasing the probability of the masterbatch contacting the blocking members 9 when passing through the discharge hopper 5, and further improving the dispersion effect of several blocking members 9 on the masterbatch feeding.

[0062] Furthermore, the material retaining member 9 preferably has a second driving surface 91 at one end thereof near the discharge hopper 5 toward the secondary conduit 2, and the second driving surface 91 is preferably an inclined surface. The contact between the masterbatch and the material retaining member 9 mainly refers to the contact between the masterbatch and the second driving surface 91. When the masterbatch contacts the second driving surface 91, the masterbatch will apply a force to the second driving surface 91, and the force will drive the material retaining member 9 to rotate the rotating sleeve 6, and the direction in which the rotating sleeve 6 is driven to rotate after the second driving surface 91 is subjected to the force is opposite to the direction in which the rotating sleeve 6 is driven to rotate after the first driving surface 71 is subjected to the force.

[0063] When there is no blockage in the dry slices between the discharge hopper 5 and the inner wall of the mixing pipe 3, the tendency of the first driving surfaces 71 to drive the rotating sleeve 6 to rotate will be stronger than the tendency of the second driving surfaces 91 to drive the rotating sleeve 6 to rotate, that is, the rotating sleeve 6 will rotate relative to the discharge hopper 5 due to the force of the first driving surfaces 71; when the dry slices are blocked between the discharge hopper 5 and the inner wall of the mixing pipe 3, the tendency of the first driving surfaces 71 to drive the rotating sleeve 6 to rotate will be weaker than the tendency of the second driving surfaces 91 to drive the rotating sleeve 6 to rotate, that is, the rotating sleeve 6 will rotate relative to the discharge hopper 5 due to the force of the second driving surfaces 91, and at this time, during the rotation of the rotating sleeve 6, the first driving surfaces 71 will drive the dry slices in contact with them to move along the length direction of the guide bar 7 toward the direction away from the flared end of the discharge hopper 5, thereby achieving the effect of clearing the blockage, and after clearing the blockage, the dry slices will continue to be fed through the channel 10.

[0064] The implementation principle of a feeding structure for spinning production in the embodiment of the present application is as follows:

[0065] When the dry chips and masterbatch are fed simultaneously through the feeding structure, the masterbatch is fed from the auxiliary pipe 2 into the mixing pipe 3 and then merges with the dry chips under the guidance of the discharge hopper 5; the dry chips are fed from the main pipe 1 into the mixing pipe 3 and then pass through the space between the discharge hopper 5 and the inner wall of the mixing pipe 3. The discharge hopper 5 can change its position under the push of the dry chips, so that the space for the dry chips to pass through is expanded, making it easier for the dry chips to pass through.

[0066] When the dry chips pass smoothly through the space between the discharge hopper 5 and the inner wall of the mixing pipe 3, the dry chips can drive the rotating sleeve 6 to rotate, reducing the probability of the dry chips being blocked between the discharge hopper 5 and the inner wall of the main pipe 1; and during the rotation of the rotating sleeve 6 relative to the discharge hopper 5, the plurality of vibration components 8 can vibrate the discharge hopper 5, and the discharge hopper 5 then transmits the vibration to the end of the auxiliary pipe 2 close to its own discharge port, thereby reducing the probability of the masterbatch being blocked at the discharge port of the auxiliary pipe 2;

[0067] Several blocking members 9 can make the masterbatch discharge more dispersed, further reducing the probability of blockage caused by the masterbatch and dry chips gathering in the main pipe 1; and when the dry chips are blocked between the discharge hopper 5 and the inner wall of the mixing pipe 3, the masterbatch contacts the blocking member 9, which can drive the rotating sleeve 6 to rotate in the opposite direction, and has the effect of clearing the blockage at the location where the dry chips are blocked.

[0068] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
