Background

The scutching and carding combined feeding box is a bridge connecting the scutching unit and the carding machines, is arranged at the rear part of each carding machine, fully opens and removes the cotton and cotton type chemical fiber which are fully opened and removed by the scutching equipment through a pipeline, and feeds the flat cotton with extremely high transverse and longitudinal uniformity to the carding machines. The lower cotton box device in the existing cotton feeding box generally adopts a mesh plate form, but the mesh plate form has many disadvantages. As shown in figures 1 to 2, during operation, the opened fibers 23 enter the device through the cotton inlet 21, and due to the ventilation effect of the meshes of the mesh plate 25, the dust particles, short fibers and fine impurities in the lower cotton box are discharged to the static pressure box 24 through the meshes of the mesh plate 25 and are discharged or sucked away through the pipeline. A pressure sensor 22 installed at the cotton inlet 21 for detecting the cotton filling pressure of the device, and when the pressure of the device is detected to be increased, the front cotton supply is decreased; on the contrary, cotton supply is increased. When the meshes of the mesh plate 25 are completely blocked, the cotton filling pressure quickly reaches the pressure set upper limit to stop cotton supply, and the ventilation height C of the mesh plate 25 is limited to be between 200mm and 400 mm. Therefore, as shown in fig. 3, the transverse cotton-filling top of the device is limited within the air-permeable height C, so that the transverse cotton-filling height of the device fluctuates greatly, and transverse cotton storage is not uniform.

Detailed Description

The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings.

As shown in fig. 4 to 6, the present invention provides a lower hopper device capable of accurately controlling the horizontal cotton filling height, which comprises a cotton inlet channel 1, wherein the cotton inlet channel 1 is in an inclined state, a pressure sensor 3 is arranged in a cotton inlet 2 of the cotton inlet channel 1, the pressure sensor 3 is externally connected with a cotton inlet device, the inclined bottom end of the cotton inlet channel 1 is inserted into a cotton feeding plate 9 of a carding machine and corresponds to a cotton feeding roller 10 in the cotton feeding plate 9 of the carding machine, a vent 6 is arranged at the top end of the cotton inlet channel 1, a grid 5 is arranged outside the vent 6, the grid 5 is connected with the outer wall of the cotton inlet channel 1, a suction pipe 7 is arranged outside the grid 5, the suction pipe 7 is connected with the grid 5 through a connecting channel 8, an air inlet 801 of the connecting channel 8 is the same as and corresponds to the size of the vent 6, the height B of the air inlet 801 is limited to 10mm to 80mm, air supply ports 701 are arranged in two ends of the suction pipe 7, and the air supply ports 701 are centrosymmetric and have the same size.

The specific working principle is as follows: during operation, fibers 4 loosened in the front enter the cotton inlet channel 1 through the cotton inlet 2, and due to the fact that the grating 5 and the suction pipe 7 act on the ventilation opening 6 at the top end of the cotton inlet channel 1, micro dust, short fiber and fine impurities in the lower cotton box flow out of the ventilation opening 6, are filtered by the grating 5 and are discharged into the suction pipe 7 through the connecting channel 8, and the impurities in the suction pipe 7 are removed or sucked away through the pipeline. The pressure sensor 3 arranged at the cotton inlet 2 is used for detecting the cotton filling pressure of the device, and when the cotton filling pressure is detected to be increased, the front cotton supply is reduced; on the contrary, cotton supply is increased. When the air vent 6 is completely blocked, the cotton filling pressure quickly reaches the pressure set upper limit and the cotton supply is stopped. Since the size of the air suction port 801 is the same as that of the ventilation port 6, and the ventilation height B of the ventilation port 6 is limited between 10mm and 80mm, the transverse cotton filling top of the device is also limited near the ventilation height B, and therefore, the precise control of the transverse cotton filling height is realized.

The suction pipe 7 has an air supply port 701 at each end to ensure a proper suction pressure to prevent the fibers 4 from being adsorbed on the corresponding air vents 6 of the grille 5.

The utility model relates to a lower hopper device capable of accurately controlling the transverse cotton filling height, the utility model has the same size and correspondence of an air suction port 801 and an air vent 6, so that the air vent height of the air vent 6 corresponding to a grating 5 and a suction pipe 7 is also B, and B is limited to 10 mm-80 mm, thereby ensuring that the transverse cotton filling height is controlled near the air vent height B, ensuring that the transverse cotton filling height is accurately controlled, and creating conditions for forming transverse, longitudinal, uniform and stable cotton storage; the utility model discloses suction pipe 7 both ends respectively have a moisturizing mouth 701 to communicate with each other with the atmosphere to keep the inside appropriate cotton pressure of inhaling of suction pipe 7, avoided adsorbing fibre 4 on the ventilative mouthful 6 that grid 5 corresponds.
