In the actual production operation, if a suction opening 610 is formed on the left suction opening 61 or the right suction opening 62 at the position corresponding to the mesh hole 5, when the suction system 6 is started, an over-high negative pressure is easily generated at the suction port 610, the cotton net and the leather ring on the leather ring are adsorbed on the suction port 610, the separation of cotton bundles is influenced, and the running of the leather ring is also influenced, in order to overcome the defect, the end suction port 611 is arranged at one end of the suction port far away from the long suction pipe 60, the end suction port 611 is a fully-open suction port, when the suction system 6 is started, the suction port 610 generates the negative pressure, meanwhile, the end suction port 611 can enable the air flow in the whole air suction system 6 to flow, so as to form a flowing air suction system, ensure the normal operation of the cotton guide device, and the end suction port 611 enables the pressure intensity of the air suction system 6 to be dispersed and balanced, and prevents the phenomenon that the cotton net is difficult to separate because the cotton net is tightly sucked by the concentrated pressure at the suction port 610.
Furthermore, the cross-sectional shape of the end suction port 611 in this embodiment is a long circular hole, as shown in fig. 2 and 4, the suction port 610 of the air suction port is communicated with the end suction port 611, the air suction port is formed in a shape like a "]", and the side wall 613 of the air suction port is arc-shaped, when the air suction system 6 is started, the leather ring and the air suction port form a long circular hole-shaped air suction structure, the air flow is sucked from the mesh hole 5 and the end suction port 611, and the air pressure at the air suction port 610 is concentrated under the action of the side wall 613 of the arc-shaped air suction port to ensure that the cotton net can be tightly sucked, the air flow is prevented from being sucked from four places to affect smooth output of the cotton bundles, meanwhile, the air pressure at the end suction port 611 can be balanced to prevent the air pressure at the air suction port 610 from being too large, and the suction.
Example 5
As shown in fig. 5, the carding machine apron cotton guide device of the embodiment is further improved on the basis of the embodiment 4, the shortest distance between the left air suction opening 61 and the left apron 3 is d, and d is greater than or equal to 2mm and less than or equal to 4 mm.
In the embodiment, the shortest distance between the left air suction opening 61 and the left leather ring 3 is controlled to be not less than 2mm and not more than 4mm, and the shortest distance between the right air suction opening 62 and the right leather ring 4 is controlled to be not less than 2mm and not more than 4 mm.
The suction opening can lead to the leather collar to take place the contact interference with the suction opening easily at the operation in-process with corresponding leather collar distance too closely, influences the leather collar life-span, and the suction opening is far away too far away at the negative pressure undersize that mesh hole 5 department formed, can not play its due effect, through the experiment, the design distance is 2mm be less than or equal to d be less than or equal to 4mm reducible leather collar and guarantees sufficient negative pressure simultaneously with the contact of suction opening in the operation process, and the most preferred scheme is d 3 mm.
Further, this embodiment is provided with the dirt filter at the long tube 60 that induced drafts and the equipment junction that induced drafts, like filter screen, dust remover, dirt filter unit etc. when the induced draft system 6 of this application adsorbs the cotton net and reaches the high effect of peeling off, still can get rid of debris such as micronic dust, short-staple in the cotton net, can further improve the quality that this equipment output cotton was restrainted, consequently, still add and establish the dirt filter and prevent the equipment jam trouble that induced drafts.
Example 6
As shown in fig. 3, the cotton device is led to carding machine apron of this embodiment, is further improved on the basis of embodiment 1 ~ 5, left apron 3 includes apron, left apron driving shaft 30 and left apron driven shaft 31, left apron driving shaft 30 is close to drive unit 2 sets up and with drive unit 2 transmission type is connected, and the apron tensioning cover is established on left apron driving shaft 30 and left apron driven shaft 31.
The drive unit 2 of this embodiment includes the driving piece, action wheel 20, driving shaft 21 and bevel gear group 22, the driving piece can be motor etc, action wheel 20 is connected with the driving piece, action wheel 20 rotates under the driving piece rotates, driving shaft 21 is connected with action wheel 20, bevel gear group 22 is connected driving shaft 21 and left apron driving shaft 30 transmission mode, and make the diaxon be the perpendicular arrangement, action wheel 20 drives driving shaft 21 and rotates and drive left apron driving shaft 30 through bevel gear group 22 and rotate, the apron passes through the pulley tensioning on left apron driving shaft 30 and left apron driven shaft 31.
Example 7
As shown in fig. 3, the cotton guide device for the apron of the carding machine of the embodiment is further improved on the basis of the embodiment 6, wherein the right apron 4 comprises an apron, a right apron driving shaft and a right apron driven shaft, and the apron is tightly sleeved on the right apron driving shaft and the right apron driven shaft;
the end part of the left leather collar driven shaft 31 is fixedly connected with a belt wheel 310, and the corresponding end part of the right leather collar driving shaft is also fixedly connected with the belt wheel 310; also comprises the following steps of (1) preparing,
a belt 311, wherein the belt 311 is tensioned on the two pulleys 310 in a crossed manner.
The structure composition of the right leather collar 4 is the same as that of the left leather collar, and the motion of the right leather collar 4 is realized by the transmission of crossed belts.
Through the belt 311, more specifically the flat belt, the cross tensioning is on two band pulleys 310 that are connected in the transmission of left leather collar driven shaft 31 and right leather collar driving shaft respectively, from this, when left leather collar driven shaft 31 rotated, through belt drive mechanism for the right leather collar action wheel also obtains power, and because the belt is the cross tensioning, the rotation direction of right leather collar action wheel is opposite with left leather collar 3, has realized that left leather collar 3 rotates with right leather collar 4 in opposite directions promptly.
