Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of ES fiber production, and particularly relates to a mixing device for ES fiber production. BACKGROUND

[0002] ES fiber is a kind of bicomponent heat-bonding fiber, which is composed of two polymers of polyethylene and polypropylene, and can be bonded when heated. During the production of ES fiber, the materials of the two polymers need to be fully mixed so as to facilitate subsequent spinning and heat bonding operations, and at the same time, the fiber can stably exhibit the expected performance and stably realize heat bonding at a specific temperature.

[0003] However, the existing mixing device for ES fiber production often has the following problems during use:

[0004] 1. During the mixing stage of ES raw materials, mechanical stirring equipment is often used to mix the polyethylene particles and polypropylene particles of ES fiber raw materials. If the amount of ES fiber raw materials is large, the stirring paddle is difficult to adaptively change the stirring speed to quickly drive the rotation and turning, so that the dispersion speed of the large amount of ES fiber raw materials is significantly slowed down, and thus the dispersion uniformity of the raw material mixing is low. For example, in the set stirring time, the large amount of ES fiber raw materials may be difficult to fully disperse and mix under the fixed stirring intensity, resulting in a significant difference in the proportion of polyethylene particles and polypropylene particles in some areas compared with other areas, and thus it is difficult to achieve the ideal uniform mixing state.

[0005] 2. The polyethylene and polypropylene of ES fiber raw materials are usually transported and stored in the form of particles. During the transportation and storage process, if the environmental humidity, temperature and other conditions are not properly controlled, the particles may be extruded, rubbed and adhered to each other, and thus agglomerates are formed. The agglomerates of particles hinder the uniform mixing of the ES fiber raw material system, making it difficult for the ES fiber raw materials to be fully mixed, and resulting in uneven mixing.

[0018] Compared with the prior art, the mixing device for ES fiber production has the following advantages:

[0019] 1. This invention incorporates an adaptive mixing component. The compression of the ES fiber raw material pushes the transfer tube downwards, allowing the lower end of the transfer tube to compress the inner upper sides of the two fan-shaped expansion plates. This enables electrical contacts one and two to contact electrical contacts three and four, respectively, controlling the start of the second low-speed motor and initiating the timer. The first low-speed motor then drives the adjusting screw, causing the annular abutment to move upwards and limiting the upward movement of the conical ring. This adaptive mixing mechanism adjusts according to the feed rate of the ES fiber raw material. The mixing space of the stirring blades should be adjusted to avoid idling, which helps improve the mixing efficiency of ES fiber raw materials. At the same time, a timer can be used to send pulse signals to control the speed of the high-speed DC motor, thereby controlling the speed of the rotating pipe and the stirring rate of the stirring blades on the raw materials. This allows the stirring rate of the stirring blades to be adaptively adjusted in a positive correlation with the feed rate, so that the mixing speed can be automatically increased when the feed amount of ES fiber raw materials is large, ensuring the uniform dispersion of different amounts of ES fiber raw materials after mixing.

[0020] 2. In this invention, a uniform mixing component is provided. During the rotation of the drive pipe, several stirring blades can be driven to rotate rapidly. At the same time, a second low-speed motor can be used to drive the lifting screw to rotate slowly, so that the bevel gear ring can mesh with the bevel gear and push the bevel gear to move slowly upward. This allows the stirring blades to move upward relative to the drive pipe. When the bevel gear moves to its limit distance, i.e., when the lifting sleeve contacts the annular plate, the second low-speed motor can immediately drive the lifting screw to rotate slowly in the opposite direction. This allows the stirring blades to move up and down within the adaptively adjusted mixing space while rapidly mixing the ES fiber raw material, ensuring that the ES fiber raw material is fully mixed. Furthermore, the meshing transmission between the bevel gear and the bevel gear ring can realize the rotation of the shaft and the stirring blades, so that the several arc-shaped stirring blades can drive the raw material in different areas of the mixing cylinder to rotate and tumble, effectively improving the mixing effect of the ES fiber raw material.

[0021] 3、The pre-pulverizing assembly is arranged in the application, the rotating frame can be driven to rotate synchronously in the process of driving the rotating through pipe to rotate rapidly, the rotating rods at both ends of the rotating frame start to drive a plurality of pulverizing blades to rotate relative to the annular outer cylinder, so that the ES raw materials in the annular outer cylinder are pre-cut and pulverized, meanwhile, the rotation of the rotating rods and the plurality of pulverizing blades can be realized through the meshing transmission of the transmission gear and the inner tooth ring, so that the plurality of pulverizing blades can cut the ES fiber raw materials in the annular outer cylinder in a rotary manner, on one hand, the plurality of self-rotating pulverizing blades can stir the ES fiber raw materials, so that the ES fiber raw materials can pass through the screen holes smoothly, on the other hand, the agglomerated ES fiber raw materials can be cut and pulverized fully and uniformly, so that the agglomerated ES fiber raw materials can become granular again and pass through a plurality of screen holes to enter the mixing cylinder smoothly, through the pre-pulverization of the agglomerated ES fiber raw materials, the uniform mixing of the raw material system caused by the agglomerated ES fiber raw materials can be effectively avoided, and the mixing uniformity of the ES fiber raw materials is ensured.

[0042] 1、use, through the T-shaped blanking pipeline 26 upper end port to its inside into ES fiber raw materials, control the rotating motor 27 start to drive the helical shaft 28 rotation, so that the helical blade on the helical shaft 28 can synchronous rotation and forward extrusion ES fiber raw materials, so that ES fiber raw materials can push the adapter pipe 29 relative T-shaped blanking pipeline 26 lower, in this process, the adapter pipe 29 lower end can extrude the upper end inside of two fan-shaped expansion plate 32, because the upper end of fan-shaped expansion plate 32 is arc structure, so two fan-shaped expansion plate 32 and two groups of slide bar 31 can move in opposite directions, in turn make two resist pieces 34 on the first electric contact 36 and the second electric contact 37 can be respectively with the third electric contact 38 and the fourth electric contact 39 contact, so that the second low-speed motor 19 starts to start and drive the adjusting screw 20 rotation, so that the guide block 21 starts to drive the annular resistance plate 22 by connecting rod up, to adjust the lifting sleeve 17 and the bevel gear ring 18 lifting distance, namely can adjust the stirring paddle 13 mixing space, avoid stirring paddle 13 in the mixing process there is idle phenomenon, conducive to improve the stirring efficiency of ES fiber raw materials, while the second electric contact 37 and the fourth electric contact 39 contact can control the timer 40 start timing, the timer 40 in timing end, that is, after the completion of feeding, will send pulse signal to the drive circuit input end of high-speed DC motor 8, to control the average voltage and rotating speed of high-speed DC motor 8, in turn can rotate the rotating speed of pipe 6 and the stirring rate of stirring paddle 13 to raw materials, so that the stirring rate of stirring paddle 13 can be positively correlated with the amount of raw materials to adaptively adjust, so that the stirring speed can be automatically increased when the amount of ES fiber raw materials is more, ensure that the dispersion uniformity of different ES fiber raw materials after mixing;

[0043] 2. During the mixing of ES fiber raw materials, the high-speed DC motor 8 drives the second external gear ring 9 to rotate. The meshing transmission between the second external gear ring 9 and the first external gear ring 7 drives the rotating pipe 6 to rotate, which in turn drives several stirring blades 13 to rotate rapidly. At the same time, the second low-speed motor 19 is started, which drives the lifting screw 16 to rotate slowly, so that the lifting sleeve 17 and the bevel gear ring 18 begin to move slowly upward. The bevel gear ring 18 pushes the bevel gear 14, so that the rotating shaft 12 and several stirring blades 13 can move upward relative to the limiting frame 10 and the rotating pipe 6. When the bevel gear ring 18 moves to the limit distance, the lifting sleeve 17 contacts the annular abutment plate. At 22:00, the second low-speed motor 19 can immediately drive the lifting screw 16 to rotate slowly in the opposite direction. At this time, the rotating shaft 12 and several stirring blades 13 move downwards by their own gravity, so that the stirring blades 13 can move up and down in the adaptively adjusted mixing space while rapidly stirring the ES fiber raw material, so as to ensure that the ES fiber raw material can be fully mixed. Furthermore, the meshing transmission of the bevel gear 14 and the bevel gear ring 18 can realize the rotation of the rotating shaft 12 and several stirring blades 13, so that several arc-shaped stirring blades 13 can drive the raw material in different areas of the mixing cylinder to rotate and tumble, thereby effectively improving the mixing effect of the ES fiber raw material.

[0044] 3. When the drive rotating pipe 6 rotates rapidly, it can synchronously drive the rotating frame 41 to rotate, so that the rotating rods 42 at both ends of the rotating frame 41 start to drive the several crushing blades 43 at their lower ends to rotate relative to the annular outer cylinder 2, so as to pre-cut and crush the ES raw material entering the annular outer cylinder 2. During the rotation of the rotating frame 41 and the rotating rods 42, the meshing transmission of the transmission gear 47 and the internal gear ring 46 can realize the rotation of the rotating rods 42 and the several crushing blades 43, so that the several crushing blades 43 can perform rotary cutting of the ES fiber raw material inside the annular outer cylinder 2, on the one hand, self- The rotating shredder blades 43 can agitate the ES fiber raw material, preventing it from accumulating and clogging at the sieve holes 3, thus maintaining the permeability of the ES fiber raw material through the sieve holes 3. On the other hand, they can fully and uniformly cut and shred the agglomerated ES fiber raw material, so that the agglomerated ES fiber raw material can be transformed back into granules and smoothly enter the mixing cylinder 1 through the sieve holes 3. By pre-shredding the agglomerated ES fiber raw material, the agglomerated ES fiber raw material can be effectively prevented from hindering the uniform mixing of the raw material system, thus ensuring the uniformity of the mixing of the ES fiber raw material.
