Description

Technical Field

[0001] The present application relates to the technical field of spinning boxes, and in particular to a pipeline-type flow channel multi-component spinning box body. Background Art

[0002] The spinning box, also known as the spinning insulation box, is the main component of the screw extrusion spinning machine. It is in the shape of a rectangular box with an insulation layer on the outside. The outside of the rectangular box is equipped with an exhaust duct, an oil inlet pipe connected to the oil pump, and an oil outlet pipe. Inside the box are melt distribution pipes, metering pumps, and spinneret components. The exhaust duct is connected to the external exhaust device;

[0003] Spinning boxes are classified into T-type flow box, fishtail flow box, straight flow box and hanger flow box according to the shape of the flow box; at the same time, spinning boxes are classified into single-component spinning boxes and multi-component (more than two components) spinning boxes according to the number of spinnable components. Among them, the hanger-type flow box can be divided into two types according to the heating method: oil heating and electric heating.

[0004] The hanger-type flow channel two-component spinning box is mainly composed of a spinning box, a melt feed pipe, a hanger-type flow channel cavity, a melt distribution plate, an electric heating tube, a thermal resistor, an upper monomer suction duct, a lower monomer suction duct and a spinneret assembly;

[0005] When the hanger-type flow channel two-component spinning manifold is used, two different polymer components are respectively transported to the spinning manifold through the melt feed pipe. The two melts entering the spinning manifold are distributed in the hanger-type flow channel. After the melt enters the hanger-type flow channel from the inlet, the melt is evenly diverted to both sides. In the hanger-type flow channel, the two melts begin to mix preliminarily during the diversion and flow process. After mixing and homogenizing, the two-component melt is accurately metered by a metering pump or other metering device. The metered melt is transported to the spinning assembly. In the spinning assembly, the melt is extruded through the spinneret holes on the spinneret to form a thin stream of fiber. During the extrusion process, the heating and insulation system in the spinning box will maintain the temperature of the melt, so that it maintains good fluidity, ensuring the smooth extrusion and molding of the fiber. Finally, the outlet position is sucked through the suction duct to remove the exhaust gas discharged from the outlet. At the same time, some impurities generated during the spinning process can be removed, such as incompletely melted raw material particles, flying flowers (fiber debris), etc.

[0006] However, during the spinning process, the waste gas and impurities discharged from the spinning box outlet contain fiber debris. These fiber debris can easily adhere to the lower monomer suction duct. Because the fibers themselves have a certain degree of flexibility and viscosity, when they enter the suction duct with the airflow, they may adhere to the duct wall due to friction with the inner wall of the duct, static electricity or changes in airflow velocity; at the same time, if incompletely melted raw material particles are brought out during the spinning process, these particles may also be deposited in the lower monomer suction duct. Due to the irregular shape and certain weight of the particles, when the airflow velocity decreases or encounters protrusions, corners and other parts in the duct, they will settle down, and as the impurities continue to adhere and accumulate in the lower monomer suction duct, the most direct impact is the blockage of the duct. When the impurities accumulate to a certain extent, the effective cross-sectional area of ​​the duct will be reduced, resulting in an increase in the resistance to airflow. Therefore, it is necessary to provide a duct-type flow channel multi-component spinning box to solve the above problems.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0046] Embodiment 1: This embodiment describes the structure and working principle of a pipeline flow channel multi-component spinning box, specifically:

[0047] like Figure 1-Figure 4 As shown, the present application provides a pipeline flow channel multi-component spinning manifold, including a spinning manifold 1, on which two groups of melt feed pipes 101 are fixedly installed, one end of the melt feed pipe 101 extends into the interior of the spinning manifold 1, and the two groups of melt feed pipes 101 are suitable for conveying melts of different components, and a hanging frame 105 is fixedly installed on the spinning manifold 1, and the hanging frame 105 is suitable for conveniently hanging the spinning box to a designated position during the installation process of the spinning box;

[0048] Two sets of hanger-type flow channels 2 are fixedly installed inside the spinning manifold 1, and flow channel cavities 201 are provided inside the hanger-type flow channels 2. The two sets of flow channel cavities 201 are suitable for melts of different components to pass through, and the hanger-type flow channels 2 have an inlet and an outlet, so that after melts of different components enter the flow channel cavity 201 in the hanger-type flow channels 2 through the inlet of the hanger-type flow channels 2, the flow channels gradually widen like hangers, and the melts are evenly diverted to both sides;

[0049] like Figure 3-Figure 5 As shown, a plurality of groups of heating tubes 3 are fixedly installed in the spinning manifold 1, and the heating tubes 3 are suitable for maintaining the temperature of the melt so that it maintains good fluidity, and a spinneret mechanism 4 is arranged at the outlet of the hanger-type flow channel 2, and the spinneret mechanism 4 includes a feed plate 401 fixedly installed at the outlet of the hanger-type flow channel 2, and the feed plate 401 has two groups of feed ports, so that the two groups of melts of different components are suitable for entering from the two feed ports of the feed plate 401 respectively;

[0050] At the same time, a filter screen (not shown in the figure) is arranged at the lower end of the feed plate 401, and the filter screen is suitable for filtering two groups of melts of different components, and a first distribution plate 402 and a second distribution plate 403 are arranged in sequence at the lower end of the filter screen, and the first distribution plate 402 and the second distribution plate 403 are used to change the flow direction of the two groups of melt raw materials of different components;

[0051] A first spinneret 404 and a second spinneret 405 are sequentially arranged at the lower end of the second distribution plate 403. The first spinneret 404 and the second spinneret 405 are suitable for extruding two groups of melts of different components after filtering, distribution and mixing into fiber streams. When the melt reaches the first spinneret 404 and the second spinneret 405, the melt is extruded through the numerous spinneret holes on the first spinneret 404 and the second spinneret 405 to form a continuous fiber stream.

[0052] A filament outlet 104 is provided at the lower end of the second spinneret 405, and the filament outlet 104 is suitable for providing an output channel for the fiber streams extruded from the second spinneret 405, so as to ensure that the fiber streams are guided out along a predetermined path, and to prevent the fiber streams from being entangled or dispersed in the spinning box;

[0053] It should be noted that, through Figure 10-Figure 15 As shown, the flow direction changes of the two groups of molten raw materials with different components and the final spinning conditions are described respectively when the two groups of molten raw materials with different components pass through the feed plate 401, the first distribution plate 402, the second distribution plate 403, the first spinneret 404 and the second spinneret 405 in sequence;

[0054] First, two groups of melt raw materials with different components, namely, material A in the red hole and material B in the green hole, enter the feed plate 401 through their respective melt feed pipes 101. At the feed plate 401, the two melts enter through two groups of feed ports respectively. At this time, the two groups of melt raw materials are in a relatively parallel or separated state and have not yet begun to mix or distribute. Fig.10 As shown, the positions where the two melt raw materials enter can be shown;

[0055] When the molten raw material enters the first distribution plate 402, its flow direction will change for the first time. The main function of the first distribution plate 402 is to start the preliminary flow adjustment and distribution of the two melts. Fig.11 In the process, a longitudinal guide groove (not shown) is provided on the first distribution plate 402. Due to the presence of the longitudinal guide groove, two groups of melt raw materials of different components are arranged in a staggered manner. At this time, the originally relatively parallel melts of material A and material B begin to intersect with each other, achieving a preliminary mixing trend.

[0056] The molten raw material passing through the first distribution plate 402 then enters the second distribution plate 403. In the second distribution plate 403, the flow direction of the molten raw material will further change, such as Fig.13As shown, it can be seen that the second distribution plate 403 is provided with transverse guide grooves (not marked in the figure), which allow the two groups of melt raw materials of different components to be arranged in rows in an interlaced manner, thereby further adjusting the first distribution plate 402, so that the melts of material A and material B originally arranged in an interlaced manner are further mixed and redistributed. It can be imagined that on the basis of the longitudinal interlacing, a transverse rearrangement is performed, so that the two melt raw materials are mixed and distributed more evenly;

[0057] When the last two groups of molten raw materials enter the first spinneret 404 and the second spinneret 405 respectively from the second distribution plate 403, the flow direction will change. Figure 14-15 In the figure, the specific layout of the spinneret holes of the first spinneret 404 can be seen. After entering the first spinneret 404, the melts of material A and material B are extruded from the spinneret holes to form fiber streams according to the distribution of the spinneret holes. At this time, the melts of material A and material B are respectively located on both sides of the main hole of the second spinneret 405 to prepare for the subsequent parallel spinning.

[0058] Afterwards, the melts of material A and material B simultaneously enter the main hole of the second spinneret 405 from both sides of the guide hole. In the main hole of the second spinneret 405, the fiber streams of the melts of material A and material B merge together. After being extruded from the main hole of the second spinneret 405, the formed parallel filament structure will have unique properties.

[0059] In order to remove the waste gas discharged from the outlet 104 of the spinning manifold 1 and the impurities attached to the yarn, Figure 1-Figure 2 and Figure 6 As shown, a bracket 102 is fixedly mounted on the spinning manifold 1, and a suction mechanism 5 is mounted on the bracket 102. The suction mechanism 5 includes an upper monomer suction duct 501 fixedly mounted on the bracket 102. The upper monomer suction duct 501 is suitable for being connected to an external suction device to generate a certain suction negative pressure in the upper monomer suction duct 501.

[0060] A plurality of groups of lower monomer suction ducts 503 are connected to the upper monomer suction duct 501, one end of each lower monomer suction duct 503 is connected to both sides of the spinning manifold 1, and one end of each lower monomer suction duct 503 penetrates the spinning manifold 1 and faces the yarn outlet 104;

[0061] Therefore, when the external exhaust device is started, a certain suction negative pressure is generated in the upper monomer suction duct 501, and this negative pressure will be transmitted to the lower monomer suction duct 503 connected thereto. Since one end of the lower monomer suction duct 503 is facing the wire outlet 104, the waste gas and impurities at the wire outlet 104 will be sucked into the lower monomer suction duct 503 under the action of the negative pressure.

[0062] In summary: two groups of melt raw materials of different components enter the interior of the spinning manifold 1 through their respective melt feed pipes 101, and the two groups of melt raw materials entering the spinning manifold 1 enter the flow channel cavity 201 through the inlets of two groups of hanger-type flow channels 2. When the melts of different components flow in the flow channel cavity 201, they can be distributed more evenly due to the special geometric shape of the flow channels; the multiple groups of heating tubes 3 in the spinning manifold 1 are responsible for maintaining the temperature of the melt to keep it in good fluidity, and the melt enters the feed plate 401 of the spinneret mechanism 4 from the outlet of the hanger-type flow channel 2. The feed plate 401 has two groups of feed ports, and the melts of different components enter from these two feed ports. At this time, the two melts are in a relatively parallel or separated state.

[0063] Then, the melt enters the first distribution plate 402, where the two melt materials are arranged in rows and staggered through the longitudinal guide grooves, and the initial mixing begins. Then, the melt enters the second distribution plate 403, where the transverse guide grooves on the second distribution plate 403 allow the two melt materials to be arranged in rows and staggered, achieving further mixing and redistribution.

[0064] The melt after mixing and distribution enters the first spinneret 404 and the second spinneret 405. The first spinneret 404 and the second spinneret 405 have a plurality of spinneret holes. After the melt reaches the spinnerets, it is extruded from the spinneret holes to form fiber streams according to the distribution and size of the spinneret holes.

[0065] The fiber stream extruded from the second spinneret 405 is output through the outlet 104, and is connected to the external exhaust device through the upper monomer suction duct 501, generating suction negative pressure, which is transmitted to the lower monomer suction duct 503. One end of the lower monomer suction duct 503 passes through the spinning box 1 and faces the outlet 104. The waste gas and impurities at the outlet 104 are sucked into the lower monomer suction duct 503 under the action of negative pressure, and then enter the upper monomer suction duct 501 to remove volatile monomers, dust and other impurities generated during the spinning process to prevent them from having adverse effects on fiber quality and working environment.

[0066] Embodiment 2: Since the waste gas and impurities discharged from the spinning box outlet 104 during the spinning process contain fiber debris, these fiber debris are easily attached to the lower monomer suction air duct 503. At the same time, due to the irregular shape and certain weight of the particles, when the air flow speed decreases or encounters protrusions, corners and other parts in the air duct, they will settle down, thereby causing the impurities to continuously adhere and accumulate in the lower monomer suction air duct 503, thereby affecting the blockage of the air duct;

[0067] In order to facilitate the cleaning of the inner wall of the lower monomer suction duct 503, refer to Figure 6-Figure 9A notch (not shown in the figure) is provided at the bottom of the lower monomer suction air duct 503, and a storage portion 506 is connected to the notch. A chamber connected to the lower monomer suction air duct 503 is provided inside the storage portion 506. A spring 507 is fixedly installed at one end of the inner wall of the chamber, and a piston 508 is fixedly installed at one end of the spring 507. In the initial state, the piston 508 is suitable for being inside the chamber under the action of the spring 507;

[0068] Meanwhile, a second cylinder 518 is fixedly installed on the outside of the storage part 506, and a pushing part 519 is fixedly installed on the telescopic end of the second cylinder 518. Meanwhile, a through groove (not shown in the figure) is provided at the bottom of the storage part 506, and a protrusion extending out of the through groove is provided at the lower end of the piston 508. The pushing part 519 is suitable for contacting with the protrusion and driving the piston 508 to move along with the extension of the second cylinder 518, so as to be suitable for pushing the piston 508 to the notch and shielding the notch to ensure the normal use of the suction mechanism 5, and the second cylinder 518 is suitable for retracting so that the piston 508 returns to the initial position under the action of the spring 507;

[0069] A collecting portion 510 is connected and installed on the storage portion 506. The collecting portion 510 is vertically arranged and has a funnel structure. A cleaning ball 511 is stored in the collecting portion 510. The cleaning ball 511 is made of rubber and has a magnetic attraction portion 520. An electromagnet 509 is fixedly installed at one end of the piston 508.

[0070] It should be noted that the magnetic attraction portion 520 has a certain weight, so that the magnetic attraction portion 520 will exert a downward force on the cleaning ball 511, so that when the magnetic attraction portion 520 falls by its own gravity, the magnetic attraction portion 520 is always at the lower end position;

[0071] It should be noted that, in the initial state, the second cylinder 518 is in the starting state, so that the piston 508 is suitable for being pushed by the telescopic end of the second cylinder 518 and is in the notch position, and the electromagnet 509 is in the energized state, and a controller is installed on the spinning manifold 1, and a sensor (not shown in the figure) is installed on the outer wall of the upper end of the lower monomer suction air duct 503 near the bend, and the sensor is suitable for sensing the position of the cleaning ball 511. When the cleaning ball 511 passes the position of the sensor, the sensor can accurately detect this position information, and at this time the sensor sends a signal to the controller, and the electromagnet 509 is controlled to be powered off through the controller;

[0072] Therefore, when it is necessary to clean the impurities on the inner wall of the lower monomer suction duct 503, the second cylinder 518 is started to drive the push part 519 to move, and the push part 519 drives the piston 508 to move into the chamber of the storage part 506. At this time, the cleaning ball 511 falls from the collection part 510 to the storage part 506 due to gravity, and is magnetically attracted to the electromagnet 509 of the piston 508 through the magnetic attraction part 520;

[0073] Then start the second cylinder 518 again to drive the pushing part 519 to push the piston 508, and the pushing part 519 pushes the cleaning ball 511 into the lower monomer suction air duct 503. Because the lower monomer suction air duct 503 is connected to the suction equipment, when the suction equipment is working, airflow will be generated in the pipe. When the cleaning ball 511 is inserted into the lower monomer suction air duct 503, the lower monomer suction air duct 503 simultaneously drives the cleaning ball 511 to move upward.

[0074] The airflow can push the cleaning ball 511 to move upward along the pipeline. During the movement, the cleaning ball 511 will continuously contact the pipe wall. Due to the long-term use of the lower monomer suction air duct 503, there are certain impurities attached to the inner wall thereof. As the cleaning ball 511 moves, the impurities are scraped off to achieve the purpose of cleaning.

[0075] When there are too many impurities in the lower monomer suction duct 503, accumulation will be formed. When the cleaning ball 511 encounters the accumulation, it will be pushed by the airflow to impact and remove the accumulation. Because the cleaning ball 511 is made of flexible material, when the accumulation cannot be cleaned at one time, it will rebound due to the impact and retreat under the pull of the spring 507, and then impact again. Therefore, the cleaning ball 511 can be pulled by the spring 507 and the airflow in the lower monomer suction duct 503. Through repeated friction and scraping, the accumulation is gradually peeled off from the tube wall. In this process;

[0076] When the cleaning ball 511 moves to a designated position in the lower monomer suction air duct 503, the sensor sends a response to the controller, and the controller controls the electromagnet 509 to be in a power-off state, so that the cleaning ball 511 is no longer restricted by the spring 507;

[0077] At the same time, the piston 508 is reset under the action of the spring 507, and is simultaneously acted upon by the pusher 519 provided at the telescopic end of the second cylinder 518, and is again located at the notch position on the lower unit suction air duct 503;

[0078] It should be noted that the diameter of the piston 508 is smaller than the diameter of the lower monomer suction air duct 503;

[0079] As another embodiment of driving the cleaning ball 511, the spring 507 can be eliminated, and the piston 508 and the pushing part 519 are fixedly installed, so that the pushing part 519 only pushes the cleaning ball 511 into the lower monomer suction air duct 503, and then the cleaning ball 511 can scrape off the dirt, scaling or other impurities on the tube wall through repeated collision and friction with the tube wall under the action of the airflow, so that the dirt, scaling or other impurities on the tube wall are peeled off from the tube wall, and then enter the upper monomer suction air duct 501 with the airflow. In this scheme, the electromagnet 509, the magnetic attraction part 520, the sensor and the controller do not need to be set, and the cleaning ball 511 is completely driven by the airflow to move, which can also achieve the purpose of cleaning the lower monomer suction air duct 503;

[0080] Because the lower monomer suction duct 503 is vertically arranged, the cleaning ball 511 needs to overcome a large gravity when moving. In order to facilitate the movement of the cleaning ball 511 in the lower monomer suction duct 503, the lower monomer suction duct 503 needs to be adjusted to a horizontal state as much as possible to facilitate the movement of the cleaning ball 511. Specifically:

[0081] A first telescopic tube 502 is connected between the lower monomer suction duct 503 and the upper monomer suction duct 501, and the first telescopic tube 502 is suitable for telescoping to change the distance between the lower monomer suction duct 503 and the upper monomer suction duct 501; and a second telescopic tube 504 is connected between the lower monomer suction duct 503 and the spinning manifold 1, and the second telescopic tube 504 is suitable for telescoping, and a connecting tube 505 is connected to one end of the second telescopic tube 504, and the connecting tube 505 is connected to the spinning manifold 1;

[0082] The lower monomer suction duct 503 is suitable for extending the second telescopic tube 504 to synchronously stretch the first telescopic tube 502, so that the lower monomer suction duct 503 is in a first state tilted away from the spinning manifold 1, and the second telescopic tube 504 is suitable for contraction to drive the lower monomer suction duct 503 to be in a second vertical state, and the second state is the working state of the lower monomer suction duct 503, and the first state is the cleaning state of the lower monomer suction duct 503;

[0083] In order to make the lower monomer suction air duct 503 in an inclined state, so as to facilitate the cleaning ball 511 to enter the lower monomer suction air duct 503, as shown in FIG. Figure 6 and Fig. 9 As shown, a first cylinder 516 is fixedly installed on the spinning manifold 1, and the first cylinder 516 is tilted, and a first pipe clamp 517 is fixedly installed at the telescopic end of the first cylinder 516, and the first pipe clamp 517 is fixed on the lower monomer suction air duct 503;

[0084] The first tube clamp 517 is suitable for moving with the telescopic end of the first cylinder 516 to drive the lower monomer suction air duct 503 to move, so that the lower monomer suction air duct 503 is in a state of being tilted away from the spinning box body 1, and the first telescopic tube 502 and the second telescopic tube 504 are stretched synchronously, so that the cleaning ball 511 can enter the lower monomer suction air duct 503, and when moving in the lower monomer suction air duct 503, it can be affected by its own smaller gravity, so as to move and clean with the airflow.

[0085] In order to collect the cleaning balls 511 dropped into the upper monomer suction air duct 501, so as to facilitate the next pipeline cleaning, Figure 6-Figure 9 As shown, a guide slot plate 512 is connected and installed at the bottom of the upper monomer suction air duct 501, and a collection funnel 513 is fixedly installed on the guide slot plate 512. The collection funnel 513 has a through hole 514, and the diameter of the through hole 514 is larger than the diameter of the cleaning ball 511, so that the cleaning ball 511 entering the upper monomer suction air duct 501 can pass through the guide slot plate 512 and fall into the collection funnel 513;

[0086] A guide tube 515 is connected and installed at the through hole 514. The guide tube 515 is composed of a hose and a hard tube. It should be noted that one end of the hose is connected to the through hole 514, and one end of the hard tube is connected to the collecting part 510, so that the cleaning ball 511 that falls into the collecting funnel 513 falls into the guide tube 515 again due to gravity, and then falls into the collecting part 510 from the guide tube 515, so that it returns to the initial state again and is freely placed on the piston 508;

[0087] In order to make the guide pipe 515 and the lower monomer suction air pipe 503 move synchronously, so that one end of the hard pipe is aligned with the collection part 510, it is convenient to collect the cleaning ball 511. Fig. 9 As shown, a second pipe clamp (not shown) is connected between the first pipe clamp 517 and the telescopic end of the first cylinder 516, and the second pipe clamp is clamped on the guide pipe 515 in a hard pipe position, so that the guide pipe 515 is suitable for synchronous movement with the movement of the lower monomer suction air pipe 503, so that one end of the guide pipe 515 is always aligned with the collection part 510;

[0088] In the present application, a valve is provided in the guide pipe 515 , and the valve is in a closed state when the spinning manifold 1 is used for spinning, and the valve is in an open state when the spinning manifold 1 is cleaned.

[0089] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
