Abstract

The invention provides a bale opener and belongs to the technical field of non-woven machinery. The bale opener comprises a box body, the box body includes a feeding chamber, a cotton trimming cavity and a metering cotton discharge chamber. A feeding curtain is arranged at the left side of the box body, a cotton trimming mechanism is arranged in the cotton trimming cavity, a cotton stripping roller is arranged inside the metering cotton discharge chamber, a weighing metering discharge device is below the metering cotton discharge chamber, and a cotton trimming power mechanism is arranged at the top of the box body. The bale opener is characterized in that the box body further includes a front unpacking release chamber and a fiber transition cavity, a front unpacking release mechanism is arranged inside the front unpacking release chamber, the top of the box body is provided with an unpacking release power transmission unit, a conveying curtain is arranged inside the fiber transition cavity, the left end of the conveying curtain extends to the inside of the front unpacking release chamber, and the right end of the conveying curtain extends to the inside of the cotton trimming cavity; a raw cotton conveying belt is arranged at the position corresponding to the lower portions of the feeding chamber and the front unpacking release chamber, the left end of the raw cotton conveying belt corresponds to the lower portion of the right end of the feeding curtain through a feeding hole of the box body, and the right end of the raw cotton conveying belt corresponds to the upper portion of the left end of the feeding curtain through the feeding hole of the box body. The cotton trimming efficiency of the cotton trimming mechanism is improved, and the protection of the cotton trimming mechanism is facilitated.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a bag opening machine. Background technique [0002] As known in the industry, a complete set of non-woven product production equipment mainly includes an opener, a carding machine, a web-laying machine and a needle punching machine (or spunlace machine). Opening of non-woven fibers (referred to as fine opening in the industry), the opened non-woven fibers are transported to a carding machine for carding and then fed to a lapping machine for laying. Machine spunlace to form nonwoven products. [0003] From the above description, it can be seen that the reason why the package needs to be opened by the package opener before the opening machine is opened is that the non-woven fibers purchased from the market are usually in a state of strong packaging and relatively large volume. If it is dismembered, it will cause the opener to be at a loss. Therefore, the...

Problems solved by technology

Although this type of bale opener satisfies the requirement of pre-opening the solid non-woven fibers in packaging, it has the following common shortcomings: since the non-woven fibers purchased from commercial channels, that is, the aforementioned non-woven fiber raw cotton, are relatively compact, the It is often difficult to show the speed and effect of picking up fibers expected by the industry only by lifting the short and dense thorns (also called tooth nails) that act like comb teeth on the corner nail curtain, thus affecting the performance of the cotton equalization mechanism. Cotton leveling efficiency, which in turn affects the laying speed of the web-laying machine at the subsequent station, and ultimately affects the production speed of non-woven products

In addition, because the aforementioned non-woven fibers (i.e., non-woven fiber raw cotton) purchased from market channels are compact and relatively large in size, the lifting brads are easily damaged. If they are not replaced in time, it will further affect the picking of fibers. And the fiber is sent to the stripping speed of the stripping roller, and the replacement must be carried out in the shutdown state, and other equipment of the complete non-woven production line can only be passively in the shutdown state, which affects the performance of the complete production line
