Description

Technical Field

[0001] This utility model relates to the field of polyethylene fiber production technology, specifically a raw material quantitative feeding device. Background Technology

[0002] The main production methods for polyethylene fibers are melt spinning and gel spinning. In melt spinning, the polyethylene raw material is cleaned to remove surface impurities and oil, and then dried to ensure that the moisture content meets the production requirements. The treated polyethylene raw material is heated to a molten state, making it a viscous fluid. The molten polyethylene is pressurized by a screw extruder and extruded from the spinneret holes of the spinning box to form fibrous material. The extruded fibrous material is cooled and solidified in air or in a water tank to form polyethylene fibers. The cooled and solidified fibers are wound onto a bobbin to obtain polyethylene fiber filaments. In order to ensure the quality of the finished product, a quantitative structure is required to strictly control the ratio of raw materials and additives such as hydrophilic agents and plasticizers during feeding.

[0003] While current feeding devices have a certain quantitative effect, they only perform a certain amount of stirring and mixing during the hot melting process. During the hot melting process, some additives will combine with the hot-melted raw materials in the hot environment, affecting the diffusion effect and thus affecting the quality of the finished product.

Detailed Implementation

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Please see Figure 1-6 In this embodiment of the present invention, a raw material quantitative feeding device includes a feeding structure 1, a sealing structure 2, an interval gate 3, and a stirring structure 4. The feeding structure 1 includes a stirring tank 101, and a hot melt bucket 102 is fixedly installed at the bottom of the stirring tank 101. The sealing structure 2 is fixedly installed at the opening of the stirring tank 101. The interval gate 3 is fixedly installed at the interval between the stirring tank 101 and the hot melt bucket 102.

A first stirring rack 402 is fixedly installed on the upper half of the side surface of the central shaft 401, and a second stirring rack 403 is fixedly installed on the lower half of the side surface of the central shaft 401.

[0045] Specifically, the entire device is fixedly installed at the material inlet of the polyethylene fiber production equipment. The mixing tank 101 and the hot melt hopper 102 are separated by the partition gate 3. At the same time, the first mixing rack 402 and the second mixing rack 403 are respectively inserted into the mixing tank 101 and the hot melt hopper 102. The weighed and quantitatively measured polyethylene raw material is added into the mixing tank 101 through the capping structure 2. Additives such as hydrophilic agents and plasticizers are quantitatively added into each part through the capping structure 2. At this time, the first mixing rack 402 is rotated by the central shaft 401 to carry out the mixing work. After the mixing is completed, it is sent into the hot melt hopper 102 for hot melting. At the same time, the second mixing rack 403 is used to heat and stir inside the hot melt hopper 102. At this time, the inside of the mixing tank 101 is empty so that raw materials can be added and stirred simultaneously. Pre-stirring and hot melt stirring are carried out at the same time, which effectively improves the degree of mixing and improves the work efficiency.

[0046] Example 1

[0047] like Figure 2-3 As shown, in this embodiment, the feeding structure 1 also includes a heating resistance wire 103, an extrusion tube 104, an auger 105, and a first motor 106. The heating resistance wire 103 is embedded and wound in the inner wall of the hot melt bucket 102. The upper rear end of the extrusion tube 104 is connected to the lower opening of the hot melt bucket 102. The auger 105 is rotatably installed inside the extrusion tube 104. The first motor 106 is fixedly installed at the rear end of the extrusion tube 104, and the output end of the first motor 106 is fixedly connected to the auger 105.

[0048] In this embodiment, the heating resistance wire 103 is energized to heat the raw material inside the hot melt bucket 102 to perform hot melt operation. At the same time, the No. 1 motor 106 is started to rotate the auger 105, so that the hot melted material in the hot melt bucket 102 is stably and continuously extruded from the extrusion pipe 104 and quantitatively supplied to the polyethylene fiber production equipment.

[0049] like Figure 4 As shown, in this embodiment, the sealing structure 2 includes a sealing body 201, a second motor 202, a feeding port 203, a sealing door 204, a quantitative controller 205, and a flow valve 206. The sealing body 201 is fixedly installed at the opening of the mixing tank 101; the second motor 202 is fixedly installed in the middle of the upper surface of the sealing body 201, and the output end of the second motor 202 is fixedly connected to the central shaft 401; the feeding port 203 is inserted into one edge of the sealing body 201; the sealing door 204 is slidably engaged with one side of the feeding port 203; the quantitative controller 205 is fixedly installed on the other edge of the upper surface of the sealing body 201; the flow valve 206 is inserted into the edge of the sealing body 201, and the flow valve 206 is electrically connected to the quantitative controller 205.

[0050] In practice, polyethylene raw materials are added into the mixing tank 101 through the feed port 203. Various additive supply pipes are connected to the openings of various flow valves 206 and are introduced into the mixing tank 101. At the same time, the supply flow is monitored by the flow valves 206, and the quantitative controller 205 determines and controls the opening and closing of the flow valves 206 to realize the quantitative supply of additives.

[0051] Example 2

[0052] Based on Embodiment 1, in order to supplement the specific way in which the overall structure of the sealing structure 2, which was not mentioned in Embodiment 1, separates and connects the mixing tank 101 and the hot melting bucket 102.

[0053] like Figure 2 , 5As shown, in this embodiment, the interval gate 3 includes a connecting bushing 301, a moving disc 302, an external gear ring 303, a fixed disc 304, a material inlet 305, a gear 306, and a No. 3 motor 307. The connecting bushing 301 is rotatably sleeved on the middle of the central shaft 401; the moving disc 302 is rotatably sleeved on the upper half of the connecting bushing 301, and the edge of the moving disc 302 is connected to the inner wall of the mixing tank 101 via a knob; the fixed disc 304 is rotatably sleeved on the lower part of the connecting bushing 301. Half-section, the edge of the fixed plate 304 is fixedly connected to the lower edge of the inner wall of the mixing tank 101; the material inlet 305 is arranged in a ring at equal angles and interspersed in the vertical direction at the edges of the moving plate 302 and the fixed plate 304; the external gear ring 303 is fixedly sleeved on the side surface of the moving plate 302; the gear 306 meshes with one side of the external gear ring 303; the No. 3 motor 307 is fixedly installed on the outer surface of the hot melting bucket 102, and the output end of the No. 3 motor 307 is fixedly connected to the gear 306.

[0054] In practice, when materials and additives are mixed in the mixing tank 101, the material inlets 305 on the moving plate 302 and the fixed plate 304 are arranged in an alternating manner to achieve separation. After mixing is completed, the moving plate 302 is controlled to rotate by the rotating gear 306 of the No. 3 motor 307, which then rubs the outer gear ring 303. This causes the material inlets 305 on the moving plate 302 and the fixed plate 304 to overlap, allowing the materials inside the mixing tank 101 to enter the hot melting bucket 102.

[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0056] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
