Description

Technical Field

[0001] This utility model relates to the field of viscose spinning machine technology, specifically to a viscose conveying device for a viscose spinning machine. Background Technology

[0002] In the viscose fiber production process, the viscose spinning machine is the core equipment that converts viscose into fiber. The viscose conveying device is the key link connecting the viscose preparation system and the spinning machine. Viscose is a colloidal fluid with high viscosity and a complex composition, containing cellulose xanthate, sodium hydroxide, water and a small amount of impurities. During the conveying process, there are strict requirements for flow stability, pressure control and pipeline cleanliness. At present, most viscose conveying devices adopt a conveying system with horizontally laid pipelines as the main body, and cooperate with components such as metering pumps and filters to realize the transmission and distribution of viscose.

[0003] However, in practical applications, existing technologies suffer from problems. Due to the high viscosity of viscose, and the tendency for reduced flow rate or temperature fluctuations during transport, viscose tends to solidify or even become partially solidified. For horizontally laid pipelines, viscose tends to deposit at the bottom of the pipeline under gravity, which may eventually lead to pipeline blockage and severely affect the viscose transport efficiency. Therefore, we need to propose a viscose transport device for viscose spinning machines. Utility Model Content

[0004] The purpose of this utility model is to provide a viscose conveying device for a viscose spinning machine. By setting up a spiral feeding component, an annular scraper that fits against the inner wall of the conveying pipeline and is driven by a power component to move axially, and the coordinated cooperation of each component, it effectively prevents the viscose from depositing and clogging in the conveying pipeline, especially in the downstream horizontally laid pipeline at corners, and ensures the stable and efficient conveying of the viscose, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A viscose conveying device for a viscose spinning machine includes: a conveying pipeline with a feed pipe fixedly connected to its top end, and a spiral feeding assembly for preventing the viscose from solidifying and clogging inside the conveying pipeline.

[0007] An annular scraper is disposed inside the conveying pipeline, and the outer wall of the annular scraper is in contact with the inner wall of the conveying pipeline;

[0008] The positioning frame is fixedly connected to the bottom of the conveying pipeline, and the positioning frame is equipped with a power component for moving the annular scraper along the axial direction of the conveying pipeline.

[0009] Preferably, the spiral feeding assembly includes a rotating rod, one end of which is rotatably mounted on the inner wall of one side of the conveying pipeline, the other end of which passes through the conveying pipeline and is connected to a first drive motor, and an auger plate is fixedly connected to the outer wall of the rotating rod.

[0010] Preferably, the inner diameter of the annular scraper is larger than the outer diameter of the auger blade.

[0011] Preferably, the power assembly includes a screw, with its two ends rotatably mounted on the inner walls of both sides of the positioning frame. One end of the screw passes through the positioning frame and is connected to a second drive motor. A movable frame is connected to the outer wall of the screw, and one end of the movable frame passes through a conveying pipeline and is connected to an annular scraper.

[0012] Preferably, the movable frame includes a movable block, which is threadedly connected to the outer wall of the screw by a nut. A connecting rod is fixedly connected to one side wall of the movable block. The connecting rod is slidably connected to the conveying pipeline, and one end of the connecting rod passes through the conveying pipeline and is fixedly connected to the annular scraper.

[0013] Preferably, the bottom of the movable block is fixedly connected to a protrusion, and the inner bottom of the positioning frame is provided with a limiting groove that matches the protrusion. The bottom of the protrusion is slidably connected to the inside of the limiting groove.

[0014] Preferably, the vertical cross-section of the annular scraper is trapezoidal.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention provides continuous pushing force through a spiral feeding assembly, which can quickly push the adhesive through the corner and accelerate the recovery of the flow velocity in the downstream horizontal pipeline, reducing the residence time of the adhesive in the downstream horizontal pipeline. When the annular scraper moves axially under the drive of the power assembly, it can penetrate deep into the downstream horizontal pipeline at the corner to thoroughly scrape off any adhesive that may be deposited on the inner wall of the downstream horizontal pipeline, ensuring the long-term unobstructed flow of the downstream horizontal pipeline at the corner. This greatly improves the anti-clogging capability of the device in complex pipeline layouts. Through the ingenious cooperation of various components, this invention effectively solves the problem of adhesive deposition and clogging in existing horizontal pipelines by simultaneously promoting adhesive flow and timely cleaning of the pipeline inner wall. In particular, the anti-clogging effect inside the downstream horizontal pipeline at the corner is significant, which significantly improves the adhesive conveying efficiency and ensures the stable operation of the viscose spinning machine.

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A viscose conveying device for a viscose spinning machine includes: a conveying pipeline 1, with a feed pipe 2 fixedly connected to its top end; a spiral feeding assembly 3 for preventing viscose from solidifying and clogging is installed inside the conveying pipeline 1; an annular scraper 4 is installed inside the conveying pipeline 1, with the outer wall of the annular scraper 4 fitting against the inner wall of the conveying pipeline 1; the conveying pipeline 1 serves as the main channel for viscose conveying, and the viscose enters the conveying pipeline 1 through the feed pipe 2. By setting the conveying pipeline 1 as the main conveying body and cooperating with the feed pipe 2 to introduce the viscose, a mounting base is provided for the spiral feeding assembly 3 and the annular scraper 4, achieving the effect of ensuring a stable viscose conveying path and facilitating the coordinated operation of the components.

[0025] A positioning frame 5 is fixedly connected to the bottom of the conveying pipeline 1. The positioning frame 5 has a U-shaped frame structure, and a power component 6 for driving the annular scraper 4 to move is installed inside it. The power component 6 includes a screw 601. The two ends of the screw 601 are rotatably mounted on the inner walls of both sides of the positioning frame 5 through bearings. One end passes through the positioning frame 5 and is connected to the output shaft of the second drive motor 602. The second drive motor 602 is a 42 series stepper motor (torque 0.55 N·m, step angle 1.8°), which is used with a DM542 stepper driver to achieve precise speed adjustment (0-300 mm / s). This ensures that the annular scraper 4 moves smoothly. A movable frame 603 is connected to the outer wall of the screw 601 by a nut. The connecting rod 6032 of the movable frame 603 passes through the side wall of the conveying pipeline 1 and is fixedly connected to the annular scraper 4. When the second drive motor 602 starts, the screw 601 rotates, driving the movable frame 603 to move axially, thereby driving the annular scraper 4 to move synchronously. By setting the screw 601 driven by the second drive motor 602 and the movable frame 603 connected to the annular scraper 4, the effect of providing stable power to the annular scraper 4 is achieved, enabling it to move reliably along the pipeline axial direction.

[0026] The screw 601 is equipped with a dust cover (made of ABS material, 2-3mm thick). The two ends of the dust cover are sealed to the inner wall of the positioning frame 5, and a strip-shaped sliding hole is opened at the position corresponding to the connecting rod 6032, which can effectively block external dust, fibers and other impurities from adhering to the surface of the screw 601.

[0027] The bottom of the movable block 6031 of the movable frame 603 is fixedly connected to a protrusion 7. The inner bottom of the positioning frame 5 is provided with a limiting groove 8 that matches the protrusion 7. The protrusion 7 is embedded in the limiting groove 8 and slidably connected to the groove wall. During the movement of the movable block 6031, the cooperation between the protrusion 7 and the limiting groove 8 can limit the shaking of the movable block 6031. By setting the sliding cooperation structure between the protrusion 7 and the limiting groove 8, the movement direction of the movable frame 603 is precisely limited, ensuring the smooth movement of the annular scraper 4.

[0028] The spiral feeding assembly 3 is the core component that drives the flow of adhesive. It includes a rotating rod 301. One end of the rotating rod 301 is rotatably mounted on the inner wall of the conveying pipeline 1 via a bearing, and the other end passes through the side wall of the conveying pipeline 1 and is fixedly connected to the output shaft of the first drive motor 302. The first drive motor 302 is a YE2-132M-4 three-phase asynchronous motor (power 7.5kW, rated speed 1440r / min), and its speed can be adjusted (500-1500r / min) through a frequency converter to meet different conveying requirements. Auger blades 303 are uniformly fixedly connected axially on the outer wall of the rotating rod 301. When the first drive motor 302 starts, the rotating rod 301 drives the auger blades 303 to rotate synchronously, continuously pushing the adhesive. By setting the rotating rod 301 driven by the first drive motor 302 and the auger blades 303 on the outer wall, the adhesive is continuously pushed and stirred, improving its fluidity and avoiding local solidification.

[0029] The annular scraper 4 is made of wear-resistant elastic material. Its outer wall is tightly fitted to the inner wall of the conveying pipeline 1. The inner wall diameter is larger than the maximum outer diameter of the auger blade 303, ensuring that the annular scraper 4 will not collide with the auger blade 303 when it moves. At the same time, the vertical cross-section of the annular scraper 4 is trapezoidal. The inclined side of the trapezoid can enhance the scraping force on the adhesive on the pipe wall. By setting the annular scraper 4, which is fitted to the pipe wall, has an inner diameter that matches the pipe wall, and has a trapezoidal cross-section, the effect of efficiently scraping the adhesive on the pipe wall and preventing deposition is achieved without interfering with the operation of the screw feeding assembly 3.

[0030] Working principle: When the device is started, the adhesive enters the conveying pipeline 1 through the feed pipe 2. The first drive motor 302 drives the rotating rod 301 and the auger plate 303 to rotate. The auger plate 303 pushes the adhesive forward along the conveying pipeline 1, while maintaining the fluidity of the adhesive through stirring. During the conveying process, the second drive motor 602 starts according to the set frequency, drives the screw 601 to rotate, and causes the movable frame 603 to move along the direction of the limiting groove 8, which in turn drives the annular scraper 4 to move axially along the conveying pipeline 1 to scrape off the adhesive attached to the pipe wall. When the annular scraper 4 moves to the end of the pipeline, the second drive motor 602 reverses and drives the annular scraper 4 to reset, and so on in a cycle.

[0031] The continuous pushing and stirring of the spiral feeding assembly 3 prevents the adhesive from solidifying due to stagnation, while the reciprocating scraping of the annular scraper 4 removes the deposited adhesive on the pipe wall. The two work together, and with the stable movement accuracy ensured by the protrusion 7 and the limiting groove 8, they effectively prevent the blockage of the conveying pipeline 1 (especially the downstream horizontal pipeline at the corner), thus achieving efficient and stable conveying of the adhesive.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
