Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing device technology, and more specifically to a premixing device for spinning nylon staple fiber. Background Technology
[0002] Short-path spinning refers to a new method for producing synthetic staple fibers using melt spinning, where spinning and post-processing steps such as stretching, crimping, and cutting can be directly combined. Also known as compact spinning, this method reduces equipment investment and factory floor space, thereby lowering production costs, because it allows for direct integration of spinning and post-processing.
[0003] The current nylon staple fiber spinning process requires mixing and stirring of its raw materials and colors.
[0004] A search revealed Chinese patent CN216891338U, which discloses a premixing device for short fiber spinning, including a mixing device body. This premixing device for short fiber spinning improves the efficiency of mixing and stirring short fiber spinning raw materials and additives. However, it still has the following drawbacks: because the vertical mixing device mainly relies on the unidirectional lifting of vertical rotation during mixing, it is prone to stratification due to gravity. Furthermore, the material accumulated in the conical bottom of the vertical tank is not easily moved upward and mixed due to stirring, further reducing the material mixing effect.

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] Reference Figures 1-4This utility model provides a premixing device for spinning nylon staple fiber, comprising,
[0029] Horizontal mixing box 7 is used to hold materials. A discharge hole 17 is provided on one side of the horizontal mixing box 7.
[0030] The mixing mechanism is located inside the horizontal mixing box 7;
[0031] The mixing mechanism includes a mixing shaft 13 rotatably mounted inside a horizontal mixing box 7 via a sealed bearing. Two sets of inner spiral rings 16 and outer spiral rings 14, which are distributed in opposite directions, are fixed to the outer circumference of the mixing shaft 13 by bolts. The inner spiral rings 16 in the same set are located inside the outer spiral rings 14, and their spiral directions are staggered. A geared motor 4 is fixed to one side of the outer wall of the horizontal mixing box 7 by bolts, and one end of the output shaft of the geared motor 4 is fixed to the end of the mixing shaft 13.
[0032] Specifically, by starting the reduction motor 4, the rotation of the reduction motor 4 drives the mixing shaft 13 to rotate. The rotation of the mixing shaft 13 drives the two sets of inner spiral rings 16 and outer spiral rings 14 to rotate simultaneously. Since the outer ring of the outer spiral ring 14 is in contact with the inner wall of the horizontal mixing box 7, the outer spiral ring 14 can not only stir the material in the horizontal mixing box 7 when it rotates, but also scrape the inner wall of the horizontal mixing box 7 in real time, effectively preventing the material from sticking.
[0033] Furthermore, since the two sets of inner spiral rings 16 and outer spiral rings 14 are distributed in an opposing manner, and the inner spiral rings 16 are not only located inside the outer spiral rings 14, but also have staggered spiral directions, the material in the horizontal mixing box 7 can be guided to circulate and be fully mixed.
[0034] In this invention, multiple equidistant turbulence holes 15 are provided inside both outer spiral rings 14.
[0035] Specifically, the turbulence hole 15 can further improve the mixing effect of the material when the outer spiral ring 14 rotates.
[0036] A vibrating discharge mechanism is located on one side of the horizontal mixing box 7 and is connected to the discharge hole 17.
[0037] The vibratory discharge mechanism of this utility model includes a discharge hopper 18 fixed to the outer wall of one side of a horizontal mixing box 7 by bolts, and the discharge hopper 18 is connected to the discharge hole 17. Vibration motors 19 are fixed to both sides of the discharge hopper 18 by bolts. Two sliding rods 22 and a side support 20 are fixed to the outer wall of one side of the horizontal mixing box 7 by bolts. The side support 20 is fixed to the discharge hopper 18. An opening and closing frame 23 is slidably installed between the two sliding rods 22 through a sliding sleeve. The opening and closing frame 23 contacts and blocks the discharge hole 17. An opening and closing cylinder 21 is provided on the top of the side support 20 to drive the opening and closing frame 23 to move in the vertical direction. The lowest point of the discharge hole 17 is flush with the bottom inner wall of the horizontal mixing box 7.
[0038] Specifically, during material discharge, the opening and closing cylinder 21 is activated, which shortens and drives the opening and closing frame 23 to move upward along the slide rod 22, thereby unblocking the discharge hole 17. As a result, the material that has been mixed in the horizontal mixing box 7 can flow into the discharge hopper 18 through the discharge hole 17 and be discharged through the discharge hopper 18. At the same time, two vibration motors 19 are activated, which rotate and generate vibration. The discharge hopper 18 and the horizontal mixing box 7 resonate, thus effectively improving the discharge rate and preventing material adhesion.
[0039] A tilting support mechanism is located below the horizontal mixing tank 7 and detaches the horizontal mixing tank 7 from the ground.
[0040] The flip-type support mechanism of this utility model includes a base frame 1, which is hinged to one end of a horizontal mixing box 7. Two guide rails 11 are fixed to the other end of the horizontal mixing box 7 by bolts. A slide table 10 is slidably installed on one side of the guide rail 11. A connecting bracket 8 is fixed to one side of the slide table 10 by bolts. A vertical fixing seat 12 is fixed to one side of the guide rail 11 near the top by bolts. A support spring 9 is fixed between the vertical fixing seat 12 and the slide table 10 by bolts. Two flip cylinders 3 are hinged inside the base frame 1, and one end of the piston rod of the flip cylinder 3 is hinged to the connecting bracket 8. Two support frames 2 for supporting the horizontal mixing box 7 are fixed inside the base frame 1 by bolts. When the bottom of the horizontal mixing box 7 contacts the top of the support frame 2, the horizontal mixing box 7 is in a horizontal state.
[0041] Specifically, in order to improve the discharge efficiency, the tilting cylinder 3 can be activated during discharge. The extension of the tilting cylinder 3 pushes the connecting bracket 8 and the slide table 10 to move upward along the guide rail 11. At this time, the support spring 9 is shortened by force and generates elastic force. When the elastic force is greater than the horizontal mixing box 7 and the weight of the material, the horizontal mixing box 7 tilts. Since the horizontal mixing box 7 is in a tilted state, the material discharge efficiency is effectively improved.
[0042] Furthermore, since the vibration motor 19 causes the discharge hopper 18 and the horizontal mixing box 7 to resonate, the horizontal mixing box 7 and the tilting cylinder 3 are supported by the support spring 9, thus further expanding the amplitude of the horizontal mixing box 7 and further improving the discharge effect.
[0043] It should be noted that the cylinder used in this application is a power actuator that converts the pressure energy of compressed air into mechanical energy. By controlling the gas in and out, it drives the piston to perform linear reciprocating motion. It can be used in conjunction with a magnetic switch, proximity switch or photoelectric switch to achieve precise control of the extension and retraction displacement of the cylinder piston rod. Those skilled in the art can set it according to actual needs, which will not be elaborated here.
[0044] In this utility model, a cover plate 6 is hinged to one side of the horizontal mixing box 7 to prevent material from splashing during mixing. A gas spring 5 is provided on one side of the horizontal mixing box 7 to assist in opening and closing the cover plate 6.
[0045] Specifically, the gas spring 5 provides support for the cover plate 6 after it is opened, making it simple and convenient to use.
[0046] It should be noted that the motors, gas springs, etc. used in this application are all existing technologies. A gas spring consists of a pressure cylinder, a piston rod, a piston, a sealing guide sleeve, and a filling material (inert gas or oil-gas mixture). An inert gas or oil-gas mixture is filled into the sealed pressure cylinder, so that the pressure inside the cavity is several times or tens of times higher than atmospheric pressure. The movement of the piston rod is achieved by the pressure difference generated by the cross-sectional area of the piston rod being smaller than that of the piston. Those skilled in the art can set it according to actual needs, which will not be elaborated here.
[0047] The use of this utility model involves the following steps:
[0048] S1: During mixing, the geared motor 4 is started, and the rotation of the geared motor 4 drives the mixing shaft 13 to rotate. The rotation of the mixing shaft 13 drives the two sets of inner spiral rings 16 and outer spiral rings 14 to rotate simultaneously. Since the outer ring of the outer spiral ring 14 is in contact with the inner wall of the horizontal mixing box 7, the outer spiral ring 14 can not only stir the material in the horizontal mixing box 7 when it rotates, but also scrape the inner wall of the horizontal mixing box 7 in real time, effectively preventing the material from sticking. Since the two sets of inner spiral rings 16 and outer spiral rings 14 are distributed in an opposing manner, and the inner spiral ring 16 is not only located inside the outer spiral ring 14, but the spiral directions are also staggered, so that the material in the horizontal mixing box 7 can be circulated and guided, and can be fully mixed.
[0049] S2: During discharge, the opening and closing cylinder 21 is activated, which shortens and drives the opening and closing frame 23 to move upward along the slide rod 22, thereby unblocking the discharge hole 17. As a result, the material that has been mixed in the horizontal mixing box 7 can flow into the discharge hopper 18 through the discharge hole 17 and be discharged through the discharge hopper 18. At the same time, two vibration motors 19 are activated. The vibration motors 19 rotate and generate vibration, and the discharge hopper 18 and the horizontal mixing box 7 resonate, thus effectively improving the discharge rate and preventing material adhesion.
[0050] S3: During the material discharge process, by activating the tilting cylinder 3, the tilting cylinder 3 extends and pushes the connecting bracket 8 and the slide table 10 to move upward along the guide rail 11. At this time, the support spring 9 is compressed and generates elastic force. When the elastic force is greater than the horizontal mixing box 7 and the weight of the material, the horizontal mixing box 7 tilts. Since the horizontal mixing box 7 is in a tilted state, the material discharge efficiency is effectively improved.
[0051] S4: Because the vibration motor 19 causes the discharge hopper 18 and the horizontal mixing box 7 to resonate, the horizontal mixing box 7 and the tilting cylinder 3 are supported by the support spring 9. Therefore, the amplitude of the horizontal mixing box 7 is further expanded, the discharge effect is further improved, and blockage and material adhesion are effectively avoided during discharge.
[0052] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.
