[0017] The present utility model will be further described below with reference to the accompanying drawings:

[0018] Such as Figures 1 to 4As shown in the figure, a weighing type precision opener includes a first opener 31, a second opener 32 and a dust collection mechanism 33. The first opener 31 includes a third frame 311, a weighing and opening mechanism 312, a first cotton feeding box 313, a supplementary cotton conveying curtain 314, a first roller opening mechanism 315 and a third cotton feeding fan 316. The weighing and opening mechanism 312 includes a transfer conveying curtain 3121, an opening needle curtain 3122, a blanking transfer bin 3123 and a weighing blanking bin 3124. The transfer conveying curtain 3121 is horizontally fixed on the third frame 311. The opening needle curtain 3122 is fixed on the third frame 311. The front end of the opening needle curtain 3122 is connected to the rear end of the transfer conveying curtain 3121. The rear end of the opening needle curtain 3122 is inclined upward. The blanking transfer bin 3123 is fixed on the third frame 311 and corresponds to the rear end of the opening needle curtain 3122. The weighing blanking bin 3124 is fixed on the third frame 311 and corresponds to the lower part of the blanking transfer bin 3123. The first cotton feeding box 313 is fixed on the third frame 311 and corresponds to the upper part of the transfer conveying curtain 3121. The supplementary cotton conveying curtain 314 is fixed on the third frame 311 and corresponds to the front end of the transfer conveying curtain 3121. The first roller opening mechanism 315 is fixed at the rear end of the third frame 311 and corresponds to the lower part of the weighing blanking bin 3124. The third cotton feeding fan 316 is fixed at the rear end of the first roller opening mechanism 315. The second opener 32 includes a second cotton feeding box 321, a second roller opening mechanism 322 and a fourth cotton feeding fan 323. The second cotton feeding box 321 is fixed at the upstream of the conveying of the second roller opening mechanism 322. The fourth cotton feeding fan 323 is fixed at the downstream of the conveying of the second roller opening mechanism 322. The third cotton feeding fan 316 is communicated with the inside of the second cotton feeding box 321 through a pipeline. The dust collection mechanism 33 is communicated with the inside of the first cotton feeding box 313 and the second cotton feeding box 321 through pipelines.

[0019] The cotton material after preliminary opening is conveyed through a pipeline to the first cotton feeding box 313. The dust collection mechanism 33 collects the dust in the first cotton feeding box 313 through a pipeline to improve the cleanliness of the cotton material. The first cotton feeding box 313 drops the cotton material downward onto the transfer conveying curtain 3121. The transfer conveying curtain 3121 conveys the cotton material backward to the front end of the opening needle curtain 3122. The opening needle curtain 3122 is evenly provided with opening needles. The cotton material is conveyed backward and upward along with the opening needle curtain 3122 and is opened. The opened cotton material is dropped into the blanking transfer bin 3123. The blanking transfer bin 3123 intermittently feeds the cotton material into the weighing blanking bin 3124. The cotton material is weighed in the weighing blanking bin 3124. When the preset weight is reached, the cotton material is dropped downward onto the first roller opening mechanism 315. The first roller opening mechanism 315 continues to open the cotton material, and the third cotton feeding fan 316 conveys the cotton material to the second cotton feeding box 321. The dust collection mechanism 33 collects the dust in the second cotton feeding box 321 through a pipeline. Similarly, the second roller opening mechanism 322 continues to open the cotton material, and the fourth cotton feeding fan 323 conveys the cotton material to the subsequent process. Through the supplementary cotton conveying curtain 314, artificial supplementary cotton can also be added to the transfer conveying curtain 3121. The advantage of this design is that it can perform multiple cotton material opening processes, enabling the cotton material to be fully dispersed, allowing the dust on the cotton material to be fully separated, and then collecting the dust in the cotton material through the dust collection mechanism 33, thereby greatly improving the cleanliness of the cotton material.

[0020] The first cotton feeding box 313 includes a cotton storage box body 3131, a cotton guiding component 3132, an exhaust component 3133, and a blanking component 3134. A cotton storage cavity is provided in the cotton storage box body 3131. The exhaust component 3133 is fixed above the cotton storage box body 3131 and is communicated with the cotton storage cavity. The blanking component 3134 is fixed below the cotton storage box body 3131. The cotton guiding component 3132 includes a guiding cylinder body 31321, a guiding top cover 31322, and a cotton inlet pipeline 31323. The guiding cylinder body 31321 is fixed above the exhaust component 3133, and the lower end opening is communicated with the exhaust component 3133. The guiding cylinder body 31321 is in the shape of a frustum of a cone, and the upper end opening area is larger than the lower end opening area. The guiding top cover 31322 is fixed above the guiding cylinder body 31321. The guiding top cover 31322 is in the shape of a cylinder. The cotton inlet pipeline 31323 is fixed on the guiding top cover 31322 and is communicated with the guiding top cover 31322. The port of the cotton inlet pipeline 31323 faces the inner side wall of the guiding top cover 31322.

[0021] The cotton material is blown into the cotton guiding assembly 3132 through the cotton feeding pipeline 31323. The cotton material first slides along the annular inner wall of the guiding top cover 31322, and under the action of gravity, it enters the guiding cylinder body 31321. Similarly, it slides along the inner wall of the guiding cylinder body 31321 and gradually moves towards the port in the middle. Then it falls from the port at the lower end of the guiding cylinder body 31321, and successively passes through the exhaust box body 31331 and the cotton storage box body 3131, and then falls on the blanking assembly 3134. The blanking assembly 3134 evenly extrudes the cotton material and drops it on the transfer conveying curtain 3121. The cotton material descends along a spiral running track in the cotton guiding assembly 3132 to the lower port, and the fiber cotton will not collide strongly with the inner wall of the cotton guiding assembly 3132, thus reducing the floating of cotton fluffs. On the other hand, the air flow in the cotton guiding assembly 3132 is stable, which is beneficial to the uniform blanking of the cotton material.

[0022] The exhaust assembly 3133 includes an exhaust box body 31331, a cylindrical net pipe 31332 and an adjusting baffle 31333. The lower end of the exhaust box body 31331 is fixed to the upper end of the cotton storage box body 3131, and the lower end of the guiding cylinder body 31321 is fixed to the upper end of the exhaust box body 31331. The cylindrical net pipe 31332 is fixed in the exhaust box body 31331. The upper end of the cylindrical net pipe 31332 is communicated with the guiding cylinder body 31321, and the lower end is communicated with the cotton storage cavity. An exhaust hole is provided on one outer wall of the exhaust box body 31331. The adjusting baffle 31333 is rotatably installed outside the exhaust box body 31331 and corresponds to the exhaust hole. A dust discharge hole is provided on the other outer wall of the exhaust box body 31331, and the dust discharge hole is communicated with the dust collection mechanism 33 through a pipeline.

[0023] The structure of the second cotton feeding box 321 is the same as that of the first cotton feeding box 313.

[0024] The cotton material falls through the cylindrical net pipe 31332, and the gas uniformly flows into the exhaust box body 31331 through the mesh holes above the cylindrical net pipe 31332 and is discharged out through the exhaust hole. By rotating the adjusting baffle 31333, the area of the exhaust hole can be controlled, so as to control the size of the air flow, and further control the falling speed of the cotton material in the cotton guiding assembly 3132. On the other hand, the dust can enter the exhaust box body 31331 through the mesh holes, so that the dust collection mechanism 33 can collect the dust from the dust discharge hole.

[0025] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
