Description

Technical Field

[0001] This utility model relates to the technical field of chemical fiber processing equipment, and in particular to a structure for conveying uniformly mixed cotton from short chemical fibers. Background Technology

[0002] In the production and processing of chemical fiber staple fibers, it is a necessary process to uniformly mix different types or batches of staple fibers. The mixing effect directly affects the quality of subsequent spinning or finished products.

[0003] Existing mixing equipment uses a mixing drum and mixing blades. The material is added from the top and mixed by the rotation of the mixing blades. However, short chemical fiber materials are loose and easy to entangle. During gravity feeding, the material will clump and bridge at the hopper inlet or screen, hindering the smooth flow of the material and causing supply interruption. In addition, when the material enters the traditional vertical mixing drum, the material will concentrate in the central area of ​​the mixing drum. However, the center linear velocity of the mixing rod is low, which cannot effectively shear and disperse the material in the center, forming a mixing dead zone and resulting in poor uniformity of the mixed material.

[0004] Therefore, this utility model proposes a uniform blending and conveying structure for chemical fiber short fibers to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the uniform cotton blending conveying structure of chemical fiber short fibers, such as easy agglomeration and blockage of materials during the feeding stage, poor material feeding continuity, and low mixing uniformity due to material accumulation in the center of the mixing drum during mixing, this utility model aims to provide a chemical fiber short fiber uniform cotton blending conveying structure with improved structure that can effectively solve the above problems.

[0006] This utility model provides a uniform blending and conveying structure for chemical fiber staple fibers, including: a feeding mechanism and a mixing mechanism disposed below the feeding mechanism. The feeding mechanism includes a feeding cylinder, a connecting frame fixedly connected to the outer wall of the feeding cylinder, a discharging cylinder rotatably connected to the bottom of the feeding cylinder, and a central rod fixedly connected to the middle of the inner wall of the discharging cylinder. The mixing mechanism includes a mixing cylinder disposed below the discharging cylinder, and a rotating rod rotatably disposed inside the mixing cylinder.

[0007] Furthermore, a vibrating hammer is fixedly connected to an adjacent side of the connecting frame. The vibrating hammer is located outside the feed cylinder and is used to apply vibration to the outer wall to prevent the material from clumping inside the feed cylinder. A second partition plate is fixedly connected to the outer wall of the central rod, which divides the inside of the discharge cylinder radially. A vibrating rod is fixedly connected to the inner wall of the central rod. The vibrating rod drives the screen installed inside the discharge cylinder to vibrate. The screen vibrates due to the drive of the vibrating rod, realizing secondary dispersion of the falling material. A dispersion disc is fixedly connected to the top of the rotating rod. The dispersion disc has a conical structure and is used to receive the falling material and guide it to the circumference of the mixing cylinder.

[0008] Preferably, a partition plate is fixedly connected to the inner wall of the feed cylinder, which divides the feed cylinder into two independent feed areas, realizing the zoned delivery of different types of materials.

[0009] Preferably, a sieve plate is fixedly connected to the middle of the inner wall of the feed cylinder and below the first partition plate. The sieve plate performs preliminary screening and bearing of the material in the feed cylinder.

[0010] Preferably, a drive ring is fixedly connected to the outer wall of the connecting frame, and the inner wall of the drive ring is rotatably connected to the outer wall of the discharge cylinder. The drive ring is used to provide driving force to make the discharge cylinder rotate, thereby realizing the alternating falling of materials in different areas.

[0011] Preferably, a rotating plate is fixedly connected to the outer wall of the rotating rod, and a leakage hole is provided at the bottom of the rotating plate. The rotating plate rotates with the rotating rod to stir the material, and the leakage hole helps the material to be evenly dispersed at the bottom of the mixing cylinder.

[0012] Preferably, a fixed base is fixedly connected to the lower part of the connecting frame, the mixing cylinder is fixedly connected to the top of the fixed base, and a discharge hole is opened at the bottom of the inner wall of the mixing cylinder for discharging the mixed material.

[0013] Preferably, an isolation cylinder is fixedly connected to the lower part of the outer wall of the feed cylinder, and the lower end of the isolation cylinder extends to the top of the dispersion disc. The isolation cylinder is used to constrain and guide the falling path of the material to prevent the material from being blown away by the airflow before mixing.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model solves the problem in the prior art of short chemical fiber materials being prone to clumping due to their light weight, which leads to clogging of the screen and discharge port, by using a vibrating air hammer set on the outer wall of the feed cylinder and a screen driven by a vibrating air rod inside the discharge cylinder. It achieves the effect of dual vibration, forced arch breaking, and ensuring loose material discharge.

[0016] 2. This utility model solves the problem in the prior art that materials tend to accumulate in the center during stirring, forming a mixing dead zone and causing uneven mixing, through the synergistic effect of the rotatable discharge cylinder, the dispersion disc at the top of the rotating rod, and the rotating plate. It achieves the effect of first dispersing and then stirring, and multi-stage uniform mixing. Attached Figure Description

The feeding mechanism 2 includes a feeding cylinder 1, a connecting frame 201 fixedly connected to the outer wall of the feeding cylinder 1, a discharging cylinder 204 rotatably connected to the bottom of the feeding cylinder 1, and a central rod 207 fixedly connected to the middle of the inner wall of the discharging cylinder 204. The mixing mechanism 3 includes a mixing cylinder 302 disposed below the discharging cylinder 204, and a rotating rod 304 rotatably disposed inside the mixing cylinder 302.

[0029] Please refer to Figure 3 , Figure 4 and Figure 5 To achieve primary vibration anti-clogging, a vibrating hammer 205 is fixedly connected to the adjacent side of the connecting frame 201. The vibrating hammer 205 is used to vibrate the outer wall of the feed cylinder 1. To achieve secondary vibration anti-clogging, a vibrating air rod 210 is fixedly connected to the inner wall of the central rod 207 in the discharge cylinder 204. The vibrating air rod 210 is connected to and drives the screen 209 to vibrate. The screen 209 is installed in the discharge cylinder 204. To achieve pre-mixing, a second partition plate 208 is fixedly connected to the outer wall of the central rod 207. The second partition plate 208 divides the inside of the discharge cylinder 204. To prevent central accumulation and mixing, a dispersing disc 308 is fixedly connected to the top of the rotating rod 304. After being dispersed by the dispersing disc 308, the material falls into the mixing cylinder 302.

[0030] In a preferred embodiment, in order to achieve independent feeding of different types of short chemical fibers, a partition plate 202 is fixedly connected to the inner wall of the feeding cylinder 1. The partition plate 202 is vertically arranged and divides the inner cavity of the feeding cylinder 1 into two independent feeding areas. In order to achieve preliminary screening and buffering of materials, a sieve plate 206 is fixedly connected to the middle of the inner wall of the feeding cylinder 1. The sieve plate 206 is located below the partition plate 202.

[0031] In a preferred embodiment, in order to achieve stable rotation drive of the discharge cylinder 204, a drive ring 203 is fixedly connected to the outer wall of the connecting frame 201. The inner wall of the drive ring 203 is rotatably connected to the outer wall of the discharge cylinder 204. The drive ring 203 drives the discharge cylinder 204 to rotate relative to the feed cylinder 1 through the built-in drive component.

[0032] In a preferred embodiment, to prevent the material from scattering during the falling process, an isolation cylinder 303 is fixedly connected to the lower part of the outer wall of the feed cylinder 1. The lower end of the isolation cylinder 303 extends to the top of the dispersing disc 308 to form a material guiding channel. In order to achieve overall support and material discharge of the device, a fixed base 301 is fixedly connected to the lower part of the connecting frame 201. The mixing cylinder 302 is fixedly connected to the top of the fixed base 301. A discharge hole 307 is opened at the bottom of the inner wall of the mixing cylinder 302.

[0033] In a preferred embodiment, in order to improve the material mixing efficiency in the mixing cylinder 302, a rotating plate 305 is fixedly connected to the outer wall of the rotating rod 304. The rotating plate 305 rotates with the rotating rod 304 to stir the material. In order to avoid the material from accumulating at the bottom of the mixing cylinder 302 and to promote flow, a leakage hole 306 is provided at the bottom of the rotating plate 305.

[0034] Working principle: When using a uniform blending and conveying structure for short chemical fibers, different types of short chemical fibers are poured into the left and right sides of the separator plate 202 respectively. The short chemical fibers fall onto the screen plate 206 inside the feed cylinder 1. The outer wall of the feed cylinder 1 is vibrated by the driven vibrating hammer 205, causing the short chemical fibers inside the feed cylinder 1 to vibrate and fall downward through the screen plate 206. When the short chemical fibers flow out through the bottom of the feed cylinder 1, the discharge cylinder 204 is rotated by the drive ring 203, causing the two types of short chemical fibers on the left and right sides of the separator plate 202 to fall into the discharge cylinder 204 in sequence. The short chemical fibers are stacked on the screen 209. The screen 209 is vibrated by the vibrating air rod 210, thereby dispersing the short chemical fibers and causing them to flow downward through the screen 209, avoiding the accumulation of short chemical fibers.

[0035] When the short chemical fibers flow out of the discharge cylinder 204, they fall down the inner wall of the isolation cylinder 303 onto the dispersion disc 308. The short chemical fibers are then dispersed into the mixing cylinder 302 through the outer wall of the dispersion disc 308. The external drive device drives the rotating rod 304 to rotate, causing the rotating plate 305 to rotate synchronously, thereby stirring and mixing the short chemical fibers inside the mixing cylinder 302. During the mixing process, the rotating plate 305 drives the short chemical fibers through the discharge hole 307 into the fixed seat 301, thus transporting them to the next processing stage.
