Description

Technical Field

[0001] This utility model belongs to the field of spinning machine technology, and in particular relates to a centrifugal spinning machine. Background Technology

[0002] Centrifugal spinning machine is a spinning device that uses centrifugal force generated by a high-speed rotating device to throw polymer melt or solution from the spinneret to form fibers. Its core fiber receiving mechanism is a rotating centrifugal tank, which uses centrifugal force to achieve stretching and twisting in the spinning process, replacing the traditional extrusion pressure. This allows the fibers to be stably wound into a filament cake without damage even when the strength is low in the wet state, and can produce filaments, short fibers and anisotropic liquid crystal fibers.

[0003] Chinese patent publication number 202322872132.0 discloses a centrifugal spinning machine. Addressing the problem that existing centrifugal spinning machines, while capable of producing fibers through the rotation of a balancing centrifugal disc, cannot cool the entire air gap hood during the spinning process, thus failing to accelerate fiber solidification and reducing production efficiency, the following solution is proposed: It includes a concave base and a housing. The outer side of the housing is slidably connected to the inner wall of the concave base. Locking casters are fixedly installed at the four corners of the bottom of the concave base to facilitate movement of the housing. A first concave plate is fixedly installed on the top of the housing, and a second concave plate is fixedly installed on top of the first concave plate. A motor is fixedly installed on the bottom inner wall of the first concave plate. A buffer mechanism cushions the housing, preventing loosening of components and extending its service life. A cooling mechanism cools the interior of the second concave plate, accelerating fiber solidification and increasing production speed.

[0004] However, existing technologies have the following problems when used: 1. In traditional centrifugal spinning, when the polymer is extruded through the separation hole, there is a lack of a mechanism to refine the filaments, making it difficult to obtain finer filaments, which affects the quality and application range of the spun products.

[0005] 2. If the polymer cannot be evenly distributed before entering the centrifugal structure, the extrusion amount at different locations will vary greatly, resulting in uneven fiber thickness and unstable quality.

[0006] 3. During the splitting and conveying process, the polymer is prone to cooling due to the influence of ambient temperature, which leads to a decrease in its fluidity. This not only affects the extrusion effect, but may also cause spinning breakage or fluctuations in fiber thickness due to insufficient fluidity, further affecting the spinning quality. Utility Model Content

[0007] The purpose of this utility model is to address the aforementioned technical problems by providing a centrifugal spinning machine, comprising: A support frame is provided, with a flow divider plate fixedly connected to its inner cavity. The flow divider plate has through holes on its sidewalls for polymer flow division. A heating chamber is provided on the top of the flow divider plate. A rotating plate is rotatably mounted inside the heating chamber. A spiral heat exchange tube for heating the flow divider plate is fixedly connected to the top of the rotating plate. A fixing plate is fixedly connected to the upper end of the inner sidewall of the heating chamber. An installation cylinder is fixedly connected to the top of the fixing plate. A conveying assembly for conveying a heat source into the spiral heat exchange tube is provided on the installation cylinder.

The pump body and the heating box are respectively connected to the first channel and the second channel. The input end of the pump body is connected to the heating box, and a discharge pipe is provided on one side of the heating box.

[0012] Furthermore, the power assembly includes a motor, which is fixedly connected to the top of the mounting frame. The power end of the motor passes through the top of the mounting frame and is fixedly connected to a second gear. A first gear is fixedly connected to the upper end of the side wall of the mounting cylinder, and the first gear meshes with the second gear.

[0013] Furthermore, a protective cover for protecting the first gear and the second gear is fixedly connected to the bottom of the fixing frame.

[0014] Furthermore, the ball is rotatably disposed in the inner cavity of the separation hole via a rotating shaft, and the top and bottom of the ball are in contact with the top and bottom of the inner cavity of the separation hole.

[0015] Furthermore, the top of the transport tube extends through the bottom of the fixture and to the top of the fixture.

[0016] Furthermore, the bottom end of the transport pipe movably passes through the top of the fixed plate and is fixedly connected to the rotating plate.

[0017] Furthermore, the upper end of the support frame is provided with a feeding pipe for feeding polymer.

[0018] Compared with the prior art, the centrifugal spinning machine of this utility model has the following advantages: 1. By setting rotatable balls inside the separation hole, the balls rotate synchronously with the filament flow during polymer extrusion, forming flexible extrusion and guidance, refining the filament diameter, obtaining finer spun products, improving spinning quality, and broadening the application range of spun products in high-precision and high-performance scenarios.

[0019] 2. By utilizing the manifold and the through holes in the sidewalls, the polymer is uniformly distributed, ensuring that the extrusion amount of the polymer entering the centrifugal structure remains consistent at different positions, thus avoiding the problem of uneven fiber thickness.

[0020] 3. The flow plate is continuously heated by the spiral heat exchange tube to maintain the required flow temperature during polymer splitting and conveying, avoiding the decrease in polymer fluidity due to cooling, and improving the overall quality and production stability of the spinning products.

[0027] like Figures 1-5 As shown, a centrifugal spinning machine includes: A support frame 100 is provided, and a flow divider 110 is fixedly connected to the inner cavity of the support frame 100. The side wall of the flow divider 110 is provided with a through hole 111 for polymer flow divider. A heating chamber 112 is provided at the top of the flow divider 110. A rotating plate 120 is rotatably provided in the inner cavity of the heating chamber 112.

A fixing frame 200 is disposed above the support frame 100, and a power component for driving the mounting cylinder 141 and the support frame 100 to rotate is provided on the fixing frame 200.

[0028] As a preferred example of this utility model, the flow divider 110 fixed in the inner cavity of the support frame 100 distributes the polymer evenly through the through holes 111 in the side wall. The heating cavity 112 at the top of the flow divider 110 provides installation space for the heating structure. A spiral heat exchange tube 121 is fixed at the top of the rotating plate 120 rotatably disposed inside the cavity. The spiral heat exchange tube 121 can heat the flow divider 110 to maintain the flow temperature required for polymer spinning. At the same time, the rotating plate 120 rotates synchronously with the support frame 100, and the conveying assembly on the mounting cylinder 141 ensures the spiral heat exchange tube... The heat source supply of 121; the centrifugal plate 150 at the bottom of the support frame 100 realizes the extrusion of polymer through the separation hole 151 on the outer wall. The ball bearing 152, which is rotated in the inner cavity of the separation hole 151, can form flexible extrusion and guidance for the filaments during the polymer extrusion process.

[0031] In the example of this application, the conveying assembly includes two sets of connecting pipes 122, which are respectively disposed at the inlet and outlet of the spiral heat exchange tube 121, and are respectively connected to the first channel 131 and the second channel 132.

[0037] In the example of this application, the bottom of the mounting bracket 200 is fixedly connected to a protective cover 250 for protecting the first gear 142 and the second gear 220.

[0038] As a preferred example of this utility model, the protective cover 250 fixed at the bottom of the fixing frame 200 forms a closed protection for the meshing first gear 142 and second gear 220, which can effectively block dust, impurities and fiber debris that may be generated during the spinning process from entering the gear meshing surface, reducing wear and jamming risks between gears.

When the polymer is extruded through the separation hole 151, the ball bearing 152 rotates synchronously with the flow of the polymer, forming a uniform flexible extrusion and guiding effect on the filament.

[0044] As a preferred example of this utility model, the bottom end of the transport pipe 130 movably passes through the top of the fixed plate 140 and is fixedly connected to the rotating plate 120, so that the transport pipe 130 can rotate synchronously with the rotating plate 120.

[0045] In the example of this application, a feeding pipe 170 for feeding polymer is provided at the upper end of the support frame 100.

[0046] As a preferred example of this utility model, the feeding pipe 170 provided at the upper end of the support frame 100 is a feeding channel for adding polymer raw materials.

[0047] In practical use, the fixing frame 200 is positioned above the support frame 100. A motor 210 fixed to the top of the fixing frame 200 serves as the power component. Its power end passes through the top of the fixing frame 200 and is fixedly connected to the second gear 220. The second gear 220 meshes with the first gear 142 fixed to the upper side wall of the mounting cylinder 141. When the motor 210 starts, it drives the mounting cylinder 141 and the support frame 100 to rotate synchronously via gear transmission. The protective cover 250 at the bottom of the fixing frame 200 covers the outside of the first gear 142 and the second gear 220. The upper part of the support frame 100... The feed pipe 170 is used to input polymer into the equipment.

The top of the transport pipe 130 extends above the fixing frame 200 and... The pump body 230 and the heating box 240 are respectively connected to the top of the fixed frame 200. The first channel 131 and the second channel 132 in the transport pipe 130 are connected to the inlet and outlet of the spiral heat exchange tube 121 through two sets of connecting pipes 122. The spiral heat exchange tube 121 is fixed to the top of the rotating plate 120. The pump body 230 pumps the heat source in the heating box 240 into the first channel 131, and then into the spiral heat exchange tube 121 through the connecting pipe 122. After heat exchange, the heat source flows back to the heating box 240 through the second channel 132 through the other set of connecting pipes 122. The exhaust on one side of the heating box 240... The outlet pipe 241 is used to discharge heat source. When the rotating plate 120 rotates with the support frame 100, it drives the spiral heat exchange tube 121 to rotate synchronously and heat the flow divider plate 110. The centrifugal plate 150, which rotates with the support frame 100, extrudes the polymer in the centrifugal chamber 153 through the separation hole 151 on the outer wall.
