Description

Pneumatic vibration cotton feeding box

Technical Field

The invention belongs to the technical field of non-woven machinery, and particularly relates to a pneumatic vibration cotton feeding box.

Background

As known in the art, the aforementioned feeder boxes, also called feeder boxes, are arranged behind the opener, i.e. in the rear of the opener, and the fully opened fibers are uniformly filled into the upper boxes by means of the action of the cotton conveying fan, then are fed into the lower boxes by means of the clamping and conveying of matched pairs of rollers, and then are picked up by the nail curtain, stripped into the vibrating bin by the beater, and uniformly spread by the vibrating plate for carding by the carding machine.

Technical information related to cotton feeding boxes such as CN2663451Y (structurally improved cotton feeding machine), CN202492630U (a new blowing-carding air pressure box) and CN101857989B (air pressure cotton feeding box) are visible in the published chinese patent literature. The hopper described in the above-mentioned patent is not limited to the hopper, and the hopper lacks a vibrating function, and thus the uniformity of sheet cotton output from the pair of cotton discharge rollers is affected to some extent.

The "a double pneumatic control cotton feeding box" recommended by CN206927983U is mentioned in lines 3 to 4 of the description of it, paragraph 0013: under the regular vibration of the vibration grid, the cotton grid can make the raw cotton of the lower cotton box produce even and compact sheet cotton, but the patent only mentions the vibration of the vibration grid, and does not mention the concrete structure for vibrating the vibration grid.

The "vertical feeding air pressure vibration cotton box" provided by CN207498546U in the paragraph 0017, especially paragraph 0025, mentions that the vibration plate swings back and forth under the action of the fluted disc mechanism and the gear rack pair, so that the fibers fall between two cotton discharging rollers (the patent name of "output rollers") with opposite rotation directions to supply an output cotton curtain (the patent name of "output curtain"). Obviously, the fluted disc mechanism mentioned in the 0012 section of the specification can enable the vibration plate to increase the swing amplitude, so that the problem of raw material remaining on the vibration plate is reduced, and the technical effect of resource utilization rate is improved. However, the structure of the fluted disc mechanism and the gear rack pair is complex, noise can be generated in the action process, the matching effect between the gear rack pair can be deteriorated due to abrasion, and the energy consumption and the maintenance workload are high. Therefore, reasonable improvements are necessary, and the technical solutions to be described below are generated in this context.
