Description

Technical Field

[0001] This application relates to the field of spinning, and in particular to a melting device for spinning. Background Technology

[0002] In the textile industry, melt spinning has a high speed and high production and processing capacity. Its working principle is to feed polymer raw materials into a screw extruder, and the rotating screw sends them to the heating zone. After extrusion and melting, the raw materials are sent forward to the metering pump. The metering pump controls and ensures that the polymer melt flows steadily into the spinning box. In the box, the melt is filtered and pressed into a porous spinneret to spray out fine melt streams. Then, the cold air blown out by the temperature-controlled air box quickly condenses the melt into solidified fiber bundles.

[0003] In existing melting processes, to prevent polymer melt from sticking to the inner wall of the melting device, a stirring device with a scraper is usually used to scrape and clean the inner wall of the device. However, in actual operation, the surface of the stirring and mixing device will inevitably be covered with polymer melt. As the scraper rotates with the stirring device, it is difficult to achieve self-cleaning of the device surface. This not only makes it inconvenient to clean the melting device later, but also causes unnecessary waste of polymer melt.

[0004] To address this issue, we propose a melting device for spinning. By installing movable parts on the surface of the mixing equipment, the surface of the mixing parts can be autonomously cleaned by utilizing the scraping effect of the movable parts moving up and down. Summary of the Invention

[0005] The purpose of this application is to improve existing spinning melting devices and provide a new spinning melting device compared to the prior art. The device includes a frame and a melting operation cylinder installed inside the frame. A heating layer is installed inside the melting operation cylinder. A rotating rod is installed inside the melting operation cylinder, and a magnetic hoop is slidably fitted onto the surface of the rotating rod. A stirring assembly is installed on the outer surface of the magnetic hoop, with its tail end in contact with the inner wall of the melting operation cylinder. The stirring assembly includes stirring plates, and stirring arc blades are installed on one side of the stirring plates. A shield corresponding to each magnetic hoop is slidably connected inside the rotating rod. The top and bottom of the shield are connected to... After the melting operation is completed inside the melting operation cylinder, the electromagnetic device activates the adjacent shields to bring them closer together, causing the two uppermost stirring components to come close together and scrape off the residue, thus achieving single-sided cleaning of the stirring components. Then, with the cooperation of the second electromagnetic strip and the magnetic rod, the surface of the stirring arc is cleaned, thus achieving comprehensive cleaning of the stirring components. At the same time, the movement of the magnetic hoop on the surface of the rotating rod can scrape off and clean the residual polymer melt on the surface of the rotating rod, and the rotating stirring components can scrape off and clean the inner wall of the melting operation cylinder, thus achieving comprehensive cleaning of the inside of the melting operation cylinder.

[0006] Furthermore, magnetic rods are symmetrically arranged on the surface of the shielding cover, and electromagnetic bars No. 1 and No. 2, which have a magnetic attraction effect on the magnetic rods, are respectively installed on both sides of the magnetic rods, and electromagnetic bars No. 1 and No. 2 are electrically connected.

[0007] Furthermore, the first and second electromagnetic bars are movably connected to the surface of the shielding cover via a hinged chain, and the inner wall of the rotating rod is provided with a limiting groove, with the tail ends of the first and second electromagnetic bars slidably connected to the limiting groove.

[0008] Furthermore, when the No. 1 electromagnetic bar is started, the edges of two adjacent stirring plates away from the stirring arc plate in the vertical direction are on the same axis, and when the No. 2 electromagnetic bar is started, the edges of two adjacent stirring arc plates away from the stirring plate in the vertical direction are on the same axis.

[0009] Furthermore, a stirring motor is installed at the top of the melting operation cylinder, and the output end of the stirring motor is connected to the top of the rotating rod. The top of the melting operation cylinder is provided with a feed inlet located on one side of the stirring motor, and a discharge pipe is installed through the bottom of the melting operation cylinder.

[0010] Furthermore, the height of the mixing assembly is greater than that of the magnetic hoop, and the vertical distance between two adjacent mixing assemblies is greater than the sum of the heights of the two mixing assemblies.

[0011] Furthermore, magnetic blocks are symmetrically arranged on the surface of the shield, and the magnetic blocks and magnetic rods are arranged at intervals. The inner wall of the magnetic hoop is symmetrically coated with a magnetic attraction coating that corresponds one-to-one with the magnetic blocks, and the magnetic attraction coating and the magnetic blocks have a magnetic attraction effect.

[0012] Furthermore, the magnetic attraction between the first and second electromagnetic bars and the magnetic rod is greater than the frictional force between the magnetic hoop and the rotating rod surface, and the magnetic attraction between the magnetic block and the magnetic hoop is greater than the sum of the weights of the magnetic hoop and the stirring assembly.

[0013] Optionally, the stirring arc blade has a hollow interior design, and a groove is provided on the surface of the stirring arc blade away from the stirring plate. An elastic metal sheet is connected to the inner wall of the groove, and an electromagnetic plate is installed on the inner wall of the stirring arc blade, and the electromagnetic plate is electrically connected to the second electromagnetic strip.

[0014] Furthermore, a heat insulation cover is fitted over the outer surface of the molten operating cylinder, and transparent columns are installed through the surface of the molten operating cylinder, with the surface of the transparent columns extending to the outside of the heat insulation cover.

[0015] Compared to existing technologies, the advantages of this application are:

[0016] (1) After the melting operation is completed inside the melting operation cylinder, the electromagnetic devices that bring the adjacent shields closer together are activated, so that the two uppermost stirring assemblies come closer together to achieve contact scraping, thereby achieving single-sided cleaning of the stirring assembly. Then, with the cooperation of the second electromagnetic strip and the magnetic rod, the surface of the stirring arc is cleaned, thereby achieving comprehensive cleaning of the stirring assembly. At the same time, during this process, the movement of the magnetic hoop on the surface of the rotating rod can scrape and clean the polymer melt remaining on the surface of the rotating rod, and the inner wall of the melting operation cylinder is scraped and cleaned by the rotating stirring assembly, thereby achieving comprehensive cleaning of the inside of the melting operation cylinder.

[0017] (2) When the No. 1 electromagnetic bar is started, the adjacent stirring plates in the vertical direction are in a state of edge contact, so that scraping and cleaning can be achieved when the two stirring components are close together. When the No. 2 electromagnetic bar is started, it drives the magnetic rod to deflect, which in turn drives the magnetic hoop connected to the magnetic block to deflect, thereby achieving the direction adjustment of the adjacent stirring arc plates in the vertical direction to meet the edge contact effect of the adjacent stirring arc plates in the vertical direction.

[0018] (3) The first and second electromagnetic bars, through the limiting groove, can ensure that the shield slides inside the rotating rod while limiting the rotation range of the magnetic rod, thus avoiding excessive deflection of the magnetic rod and affecting the deflection of the subsequent stirring assembly.

[0019] (4) When the second round of misalignment cleaning is carried out, the electromagnetic strip No. 2 is started at the same time as the electromagnetic plate, which attracts the elastic metal plate, thereby making the surface of the stirring arc plate in a concave state, preventing the polymer melt scraped off the surface of the upper stirring plate from adhering to the surface of the stirring arc plate again, thus ensuring the cleaning effectiveness.

Detailed Implementation

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Example 1:

[0034] This invention provides a melting device for spinning; please refer to [link to relevant documentation]. Figure 1 and Figures 3-7 The system includes a frame 1 and a melting operation cylinder 2 installed inside the frame 1. A heating layer is installed inside the melting operation cylinder 2. A rotating rod 6 is installed inside the melting operation cylinder 2. A magnetic hoop 8 is slidably sleeved on the surface of the rotating rod 6. A stirring assembly 7 is installed on the outer surface of the magnetic hoop 8, with its tail end in contact with the inner wall of the melting operation cylinder 2. The stirring assembly 7 includes a stirring plate 71. A stirring arc plate 72 is installed on one side surface of the stirring plate 71. A shield 81 corresponding to the magnetic hoop 8 is slidably connected inside the rotating rod 6. Electromagnets 83 are connected to the top and bottom of the shield 81.

[0035] Specifically, the electromagnets 83 can switch working modes, thereby causing two adjacent shields 81 to slide closer or further apart, thereby indirectly causing adjacent stirring assemblies 7 to misalign and stick together in the vertical direction, thus achieving the sticking, scraping and cleaning operation.

[0036] After the melting operation is completed inside the melting operation cylinder 2, the electromagnetic devices 83 at the bottom of the uppermost shield 81 and the top of the second-highest shield 81 are activated first, so that the two uppermost stirring assemblies 7 are brought closer to each other. Then, by scraping away the mutual contact between the stirring assemblies 7 in a staggered and close-fitting state, the stirring assemblies 7 are cleaned on one side. Then, the above operation is repeated. Through the step-like scraping and cleaning operation, the stirring assemblies 7 inside the melting operation cylinder 2 are cleaned. Then, with the cooperation of the second electromagnetic strip 85 and the magnetic rod 86, the surface of the stirring arc blade 72 is cleaned, thereby achieving a complete cleaning of the stirring assemblies 7. At the same time, during this process, the movement of the magnetic hoop 8 on the surface of the rotating rod 6 can scrape and clean the residual polymer melt on the surface of the rotating rod 6. And with the help of the rotating stirring assemblies 7, the inner wall of the melting operation cylinder 2 is scraped and cleaned, thus achieving a complete cleaning of the inside of the melting operation cylinder 2.

[0037] Please see Figures 5-9 The surface of the shield 81 is symmetrically arranged with magnetic rods 86. On both sides of the magnetic rods 86, there are electromagnetic bars 84 and 85 that have magnetic attraction with the magnetic rods 86, and the electromagnetic bars 84 and 85 are electrically connected.

[0038] Specifically, when the first electromagnetic bar 84 is activated, the second electromagnetic bar 85 is in the closed state, and the adjacent first electromagnetic bar 84 in the vertical direction is also in the closed state. This causes the adjacent stirring plates 71 in the vertical direction to be in an edge-fitting state. As the two stirring assemblies 7 approach each other, the residual polymer melt on the surface of the stirring plates 71 can be effectively scraped and cleaned. When the second electromagnetic bar 85 is activated, the first electromagnetic bar 84 and the adjacent second electromagnetic bar 85 are both closed, causing the magnetic rod 86 to deflect. This causes the shield 81, which is fixedly connected to the magnetic rod 86, to deflect. The deflection of the shield 81 causes the magnetically attracted ring 8, which is magnetically connected to the magnetic block 82, to deflect. This achieves the orientation adjustment of the stirring arc blades 72 inside the adjacent stirring assemblies 7 in the vertical direction, so as to meet the edge-fitting effect of the adjacent stirring arc blades 72 in the vertical direction.

[0039] Electromagnetic bar 84 and electromagnetic bar 85 are movably connected to the surface of shield 81 via a hinge chain. The inner wall of the rotating rod 6 is provided with a limiting groove, and the tail ends of electromagnetic bar 84 and electromagnetic bar 85 are slidably connected to the limiting groove.

[0040] Specifically, the first electromagnetic bar 84 and the second electromagnetic bar 85, through the limiting groove, can ensure that the shielding cover 81 slides inside the rotating rod 6 while limiting the rotation range of the magnetic rod 86, thus preventing the magnetic rod 86 from deflecting excessively and affecting the deflection of the subsequent stirring assembly 7.

[0041] When the No. 1 electromagnetic bar 84 is started, the edges of two adjacent stirring plates 71 in the vertical direction away from the stirring arc plate 72 are on the same axis. When the No. 2 electromagnetic bar 85 is started, the edges of two adjacent stirring arc plates 72 in the vertical direction away from the stirring plate 71 are on the same axis.

[0042] Specifically, when the No. 1 electromagnetic bar 84 is activated, two adjacent stirring plates 71 in the vertical direction can achieve staggered scraping and cleaning when they approach each other. When the No. 2 electromagnetic bar 85 is activated, two adjacent stirring arc plates 72 in the vertical direction can achieve staggered scraping and cleaning when they approach each other.

[0043] Please see Figure 2 A stirring motor 3 is installed on the top of the melting operation cylinder 2, and the output end of the stirring motor 3 is connected to the top of the rotating rod 6. The top of the melting operation cylinder 2 is provided with a feed port 4 located on one side of the stirring motor 3, and a discharge pipe 5 is installed through the bottom of the melting operation cylinder 2.

[0044] Specifically, driven by the stirring motor 3, the rotating rod 6 is rotated, which in turn drives the stirring assembly 7 to rotate, making the melting process inside the melting operation cylinder 2 more complete and uniform.

[0045] The feed inlet 4 is used to feed material into the melting operation cylinder 2, and the discharge pipe 5 is used to discharge the material inside the melting operation cylinder 2 after melting is completed.

[0046] The height of the mixing assembly 7 is greater than that of the magnetic hoop 8, and the vertical distance between two adjacent mixing assemblies 7 is greater than the sum of the heights of the two mixing assemblies 7.

[0047] Specifically, the distance between the magnetic hoop rings 8 is sufficient to provide enough space for staggered scraping when adjacent mixing components 7 are close to each other, thereby enabling the surface of a single mixing component 7 to be completely scraped.

[0048] The surface of the shield 81 is symmetrically arranged with magnetic blocks 82, and the magnetic blocks 82 and magnetic rods 86 are arranged at intervals. The inner wall of the magnetic hoop 8 is symmetrically coated with a magnetic attraction coating that corresponds one-to-one with the magnetic blocks 82, and the magnetic attraction coating and the magnetic blocks 82 have a magnetic attraction effect.

[0049] Specifically, the magnetic block 82 is magnetically connected to the magnetic hoop 8 through the magnetic coating. When the magnetic block 82 switches positions, the magnetic hoop 8 also slides on the surface of the rotating rod 6 to adjust its direction, thereby adjusting the position of the stirring assembly 7 and achieving misaligned fit with the adjacent stirring assembly 7 in the vertical direction.

[0050] The magnetic attraction between the first electromagnetic bar 84, the second electromagnetic bar 85 and the magnetic rod 86 is greater than the frictional force between the magnetic hoop 8 and the rotating rod 6. The magnetic attraction between the magnetic block 82 and the magnetic hoop 8 is greater than the sum of the weights of the magnetic hoop 8 and the stirring assembly 7.

[0051] Specifically, when the No. 1 electromagnetic bar 84 or the No. 2 electromagnetic bar 85 is activated, it can overcome the frictional resistance between the magnetic hoop 8 and the surface of the rotating rod 6, thereby facilitating the directional adjustment of the magnetic hoop 8. The force between the magnetic block 82 and the magnetic hoop 8 can prevent the magnetic hoop 8 from sliding down the surface of the rotating rod 6 unnecessarily, interfering with the stirring and subsequent cleaning operations.

[0052] A heat insulation cover is fitted over the outer surface of the melting operation cylinder 2. A transparent column is installed through the surface of the melting operation cylinder 2, and the surface of the transparent column extends to the outside of the heat insulation cover.

[0053] Specifically, the use of a heat insulation cover can prevent burns caused by heat overflow from the inside of the molten operating cylinder 2, while the use of transparent bars allows operators to easily check the level of the melt inside the molten operating cylinder 2 and take appropriate measures.

[0054] Example 2:

[0055] Please see Figures 10-11 Components identical or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is that the stirring arc plate 72 has a hollow interior design. A groove is provided on the surface of the stirring arc plate 72 away from the stirring plate 71. An elastic metal sheet is connected to the inner wall of the groove. An electromagnetic plate 721 is installed on the inner wall of the stirring arc plate 72, and the electromagnetic plate 721 is electrically connected to the second electromagnetic strip 85.

[0056] Specifically, in this embodiment, the surface of the stirring arc blade 72 is cleaned first, and then the surface of the stirring plate 71 is cleaned. For this purpose, it is necessary to adjust the order of starting the first electromagnetic bar 84 and the second electromagnetic bar 85. Start the second electromagnetic bar 85 first, and after cleaning the surface of the stirring arc blade 72, start the first electromagnetic bar 84 to clean the surface of the stirring plate 71.

[0057] To prevent residual polymer melt on the surface of the uncleaned stirring plate 71 from accumulating and adhering to the cleaned stirring arc plate 72 below during the scraping process, the second electromagnetic strip 85 is activated simultaneously with the electromagnetic plate 721 during the second round of staggered cleaning. This attracts the elastic metal plate, causing the surface of the stirring arc plate 72 on that side to be in a concave state. This prevents the polymer melt scraped from the surface of the upper stirring plate 71 from adhering to the surface of the stirring arc plate 72 again, ensuring the effectiveness of the cleaning.

[0058] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
