Description

Staple fiber hopper of wool blending machine

Technical Field

The utility model relates to the technical field of opening and wool equipment, in particular to a cotton hopper of a wool blending machine.

Background

In the process of making wool yarns, wool needs to be opened. In the existing production process, the wool needs to be subjected to rough opening and wool production by using rough opening equipment B262, and then the wool subjected to rough opening treatment is subjected to fine opening treatment by using fine opening equipment. Wherein the rough opening requires 2 to 3 times, and the increase of carding times can reduce the opening efficiency, and the mechanical property of wool fibers can be influenced by the two times of opening, so that the strength of the wool fibers is reduced. And after multiple opening, the fibers may become entangled with each other to form locks. When fibers with good fluffiness such as wool, acrylic fibers and the like are carded, the wool, the acrylic fibers have high moisture regain due to the fact that the wool, the acrylic fibers and the like need to be sprayed with crude oil or water. In conventional coarse opening devices, moreover, loose wool fibers pass through the hopper and fall onto the feed curtain.

In the prior art wool coarse opening and knitting machine shown in fig. 1, no ventilation openings are formed in the side wall of the cotton box, the fibers fall directly onto the feed curtain 10, and because the fibers are just coarse opened and are not completely separated from each other, the fibers are focused and agglomerated, and because the fibers are sprayed with crude oil or moisture before being fed into the dust cage 1, the moisture regain is improved. So that the water content of the fibers is increased, and the clustered fibers are unevenly distributed in the air flow, so that the clustered fibers are clustered on the feeding curtain when falling. And because of the difference of the water content of each batch of fibers, when the fibers move in the air flow in the falling process, some fibers can be close to the left side of the feeding curtain, and some fibers can be close to the right side or the middle position of the feeding curtain, so that the fibers are unevenly distributed on the feeding curtain. How to make the fiber net formed on the feeding curtain more uniform after the wool fiber passes through the dust cage and the cotton box becomes a problem to be solved.

Detailed Description

The utility model will be further described with reference to the drawings and specific examples.

Examples

The present embodiment will be described in detail with reference to fig. 2, 3 and 4. The cotton box of the wool blending machine comprises a dust cage 1 and a cotton box 2 communicated with the dust cage 1; the two opposite side walls of the cotton box 2 are provided with ventilation openings 3; an air quantity adjusting device is further arranged on one side of the ventilation opening 3.

A first inclined plate 4 and a second inclined plate 5 are also arranged in the inner space of the cotton box 2; the first inclined plate 4 and the second inclined plate 5 form a doffing space with wide upper part and narrow lower part; one end of the first inclined plate 4, which is close to the bottom of the cotton box 2, is adjacent to the first cotton conveying roller 7; one end of the second inclined plate 5, which is close to the bottom of the cotton box 2, is adjacent to the second cotton conveying roller 8.

The dust cage 1 is composed of an outer layer 20 and an inner layer 21, and the upper end of the dust cage 1 is encapsulated, and the lower end is connected with a cotton box without a baffle or the like. Wherein the outer layer is impermeable to air and the inner layer 21 is provided with a mesh for allowing air flow. And a feed inlet 22 is arranged at the upper part of the dust cage 1, the feed inlet 22 is connected with a fan through a pipeline, and the fan can convey the coarsely opened fibers into the dust cage. Because the fibers are conveyed by the air flow, when the air flow brings the fibers into the dust cage 1, most of the air flow can flow through meshes on the inner layer 21 to sandwich the outer layer 20 and the inner layer 21 and flow out through an air outlet 23 communicated with the sandwich layer 21, part of impurities can be taken away when the air flow passes through the air outlet, and a dust collecting bag is connected to the outer side of the air outlet 23 and used for collecting the impurities, wherein the dust collecting bag is not shown in the figure.

After the removal of a substantial portion of the air flow from the inner layer 21, which is approximately 60%, the remaining air flow enters the cotton box. The carried fibers also fall out of the cotton box 2. In the prior art, as shown in fig. 1, the fibers are dropped directly onto the feeding curtain 10, and since the fibers are only coarsely opened and are not completely separated from each other, the fibers are also focused and agglomerated, and further since the fibers are sprayed with crude oil or moisture before being fed into the dust cage 1, the moisture regain thereof is improved. So that the water content of the fibers is increased, and the clustered fibers are unevenly distributed in the air flow, so that the clustered fibers are clustered on the feeding curtain when falling. And because of the difference of the water content of each batch of fibers, when the fibers move in the air flow in the falling process, some fibers are close to the left side of the feeding curtain, and some fibers are close to the right side or the middle position of the feeding curtain. Resulting in an uneven distribution of fibers on the feed curtain.

In order to solve the problem of uneven distribution of the fibers in the feeding curtain 10, ventilation openings 3 are provided on two opposite side walls of the cotton box 2; a first inclined plate 4 and a second inclined plate 5 are also arranged in the inner space of the cotton box 2; the first inclined plate 4 and the second inclined plate 5 form a doffing space with wide upper part and narrow lower part. The first swash plate 4 and the second swash plate 5 are fixed and rotatable near one end of the dust cage 1. And one end of the first inclined plate 4, which is close to the bottom of the cotton box 2, is adjacent to the first cotton conveying roller 7; one end of the second inclined plate 5, which is close to the bottom of the cotton box 2, is adjacent to the second cotton conveying roller 8. And the first cotton conveying roller 7 and the second cotton conveying roller 8 have proper spacing. The first inclined plate 4 and the second inclined plate 5 are provided with meshes, so that the air flow of the cotton box 2 from the dust cage 1 can flow out of the meshes on the first inclined plate 4 and the second inclined plate 5. And due to the ventilation openings provided on both sides of the cotton box 2, part of the air flow is discharged from the ventilation openings 3.

When the fiber falls into the cotton box 2 from the dust cage 1, the fiber can firstly fall between the first cotton conveying roller 7 and the second cotton conveying roller 8, the rotation between the first cotton conveying roller 7 and the second cotton conveying roller 8 can drive the fiber on the first cotton conveying roller to fall onto the feeding curtain 10, and the time of the fiber falling onto the feeding curtain 10 can be delayed. In the process that the fiber falls, if the fiber is off one side due to the influence of the air flow and the like, the air quantity adjusting device on the opposite side is started, so that the air flow can flow out from one side of the air quantity adjusting device, the fiber can be driven to move to the side, and the position of the wool fiber between the first cotton conveying roller 7 and the second cotton conveying roller 8 can be realized, so that the fiber distribution is uniform. For example, when more fibers drop from the left side, the air quantity adjusting device on the right side is controlled to increase the air quantity on the right side, and the air flow can drive the fibers to move to the right side because the air flow flows from the left side to the right side at the moment, so that the effect of adjusting the fiber dropping position is achieved.

Further, the ventilation openings 3 are in a mesh shape and uniformly distributed in a set area of the side wall of the cotton box 2. In particular in the middle of the cotton box 2.

Further, the air quantity adjusting device can push and pull the adjusting plate 6. The adjusting plate 6 may be one piece or 2 pieces. In this embodiment, 2 adjusting plates capable of moving left and right are adopted, and part of meshes can be shielded in the moving process, so that air flow in the cotton box 2 is adjusted, and the effect on doffing of wool fibers is caused.

Further, the ventilation opening 3 is located on a ventilation board 24, and meshes are uniformly distributed on the ventilation board 24. One end of the ventilation plate is rotatably connected with the side wall of the cotton box 2, and the adjusting plate 6 is also connected with the ventilation plate. The upper and lower both sides of ventilation board all are fixed with a plurality of bolts 25, and the upper and lower both sides of regulating plate 6 are provided with the bar hole, and during the assembly, bolt and the bar hole 26 phase-match on the regulating plate 6 to be provided with the nut in the outside of bolt, can avoid regulating plate 6 landing, the nut does not screw up when adjusting, and regulating plate 6 can slide. When the adjusting plate 6 is pushed and pulled, the adjusting plate 6 can move along the strip-shaped holes, so that the air quantity is adjusted.

Further, the height of the cotton box 2 is 1.5-2.5m. In order to increase the time for doffing of wool fibers, the time of action of air convection on wool fibers is increased, thereby increasing the height of the hopper 2, which in this embodiment is chosen to be 2m. As the height of the cotton box 2 increases, the thickness of the steel plate used therefor also needs to be increased, and the thickness of the steel plate used is mentioned to be 1.5-2.5mm, and in this embodiment, 2.5mm is selected.

The feeding curtain 10 is driven to move by two rotating rollers, two ends of each rotating roller are fixed on the blocking plate 9, and in order to increase the stability strength of the equipment, the thickness of a steel plate used by the blocking plate 9 is thickened to be 2.5mm.

Further, the distance between the first inclined plate 4 and one end of the second inclined plate 5, which is close to the bottom of the cotton box 2, is adjustable.

Further, the distance between the first cotton conveying roller 7 and the second cotton conveying roller 8 is adjustable. The rotation speed of the first cotton conveying roller 7 and the second cotton conveying roller 8 can be adjusted, and the carding machine can adapt to fibers with different carding requirements.

The adjustment of the distance between the ends of the first inclined plate 4 and the second inclined plate 5 and the adjustment of the distance between the first cotton conveying roller 7 and the second cotton conveying roller 8 affect the thickness of the wool fiber net on the feeding curtain 10. If carding is larger, the distance between the two ends can be reduced, so that the thickness of the wool fiber net is reduced, and the carding process can be normally performed.

The rotation direction of the first cotton conveying roller 7 is opposite to that of the second cotton conveying roller 8, the rotation direction of the first cotton conveying roller 7 is clockwise, and the rotation direction of the second cotton conveying roller is anticlockwise, so that wool fibers in a doffing space between the first inclined plate 4 and the second inclined plate 5 can be conveyed to the feeding curtain 10.

The fleece web with a certain thickness is transported by the feeding curtain 10, a number of embossing rollers 11 are arranged on the outside of the cotton box 2 above the feeding curtain 10, three embossing rollers 11 are arranged in this embodiment, and grooves are provided on the surface of the embossing rollers 11, which can improve the friction with the fleece web. And the cotton roller 11 is made of wood, so that damage to wool fibers can be reduced. In this embodiment there are three nip rolls 11 and the two nip rolls 11 near the headbox 2 have a larger diameter than the nip roll 11 near the first feed roll 12.

A first feeding roller 12 and a second feeding roller 13 are arranged between the feeding curtain 10 and the cylinder 13, and the first feeding roller 12 and the second feeding roller 13 are both groove rollers, namely the surfaces of the first feeding roller 12 and the second feeding roller 13 are provided with grooves with a certain number and depth, so that the holding capacity of wool fibers can be improved, and the fiber web can be conveniently conveyed. The first feeding roller 12 and the second feeding roller 13 are each provided in pairs.

In the prior art coarse opening and carding device, the surface of the second feeding roller 13 is a spike, and the surface of the cylinder 14 is also a spike 19, and because the spike is thicker, the carding degree of wool fibers is not enough, in the embodiment, the spike 19 on the surface of the cylinder 14 is replaced by the carding needle 16, and the carding needle 16 is uniformly distributed on the surface of the cylinder 14. The carding action on wool fibers can be improved because of the finer card wire 16. The wolf tooth angle of the surface of the second feeding roller 13 has insufficient holding capacity for the fiber, so the improvement is that

A plurality of pairs of carding rollers 17 and stripping rollers 18 are provided above the cylinder 16, and a doffer 15 is provided on the other side of the cylinder 16. During opening and carding of the fibres, it is the carding roller 17 that interacts with the cylinder to open and card the fibres. However, during carding, part of the fibers will be wound around the carding roll 17, and the wires of the cylinder 14 will peel off the fibers wound around the carding roll 17. If the fiber winding on the carding roll 17 is relatively tight, the cylinder 14 is more difficult to peel off the fibers, and if the fiber winding on the carding roll 17 is too large, the opening and carding effects on the fibers are affected. In order to peel off the fibers wound on the carding roll 17, a stripping roll 18 is arranged on one side of the carding roll 17, so that the fibers wound on the carding roll 17 are torn loose, and the cylinder can be easily peeled off from the stripping roll. Blade clothing is used on the dividing roller 17 and the dehairing roller 18.
