The top of spindle blade 2 be equipped with and open and to have second cavity 17, the top of second cavity 17 has an iron ball 19 through second spring 18 hoist and mount, an electro-magnet 20 is installed to the bottom of second cavity 17, electro-magnet 20 circular telegram can adsorb ball 19 and lengthen second spring 18, after electro-magnet 20 outage, second spring 18 can drive ball 19 and vibrate back and forth to drive spindle blade 2 shake for a short time.

The electromagnet 20 is not positioned right below the axis of the second spring 18, when the electromagnet 20 is electrified to adsorb the round ball 19, the second spring 18 can be pulled obliquely downwards, after the electromagnet 20 is powered off, the second spring 18 and the round ball 19 vibrate in the horizontal direction in addition to the vertical direction, and the round ball 19 impacts the side wall of the second cavity 17 to shake the spindle blade 2, so that the bobbin on the upper inclined frame of the spindle blade 2 is shaken off.

The cross rod 1 is provided with a threaded hole 21, the lower end of the spindle blade 2 is provided with a bolt head 22, and the spindle blade 2 is screwed on the cross rod 1 through threads.

Two first metal rings 23 are vertically and alternately arranged in the threaded hole 21, the two first metal rings 23 are respectively connected with the positive electrode and the negative electrode of a power supply through guiding, two second metal rings 24 are vertically and alternately arranged on a thread head at the lower end of the spindle blade 2, the two metal rings are respectively communicated with the two poles of the electromagnet 20 through leads, and after the spindle blade 2 rotates in the threaded hole 21, the two second metal rings 24 are correspondingly communicated with the two first metal rings 23, so that the electromagnet 20 on the spindle blade 2 is connected into a circuit.

The top of the first cavity 8 is provided with a second air passage 25 communicated with the upper end of the spindle blade 2, and the second air passage 25 maintains that the air pressure at the upper end of the piston 13 is always the same as the atmospheric pressure.

The outer end face of the top block 11 is provided with a vertical groove 26, and when the top block 11 is contacted with the inner wall of the bobbin, the air pressure can still act on the outer end of the top block 11 through the vertical groove 26 to push the top block 11 into the mounting hole 10.

In order to facilitate the installation of the round balls 19 and the electromagnets 20, the spindle blade 2 is designed to be split at the second cavity 17.

Before the bobbin is installed, the air box 4 is pumped into negative pressure in advance through the air pump 6, the switch valve 7 between the air channel and the air box 4 is in a closed state at the moment, the first cavity 8 is at normal pressure, and the top block 11 extends out of the installation hole 10 under the action of the first spring 12; after the bobbin is inserted onto the spindle rods 2, the lower end of the bobbin is supported on the top block 11, the switch valve 7 is opened at the moment, the air box 4 is communicated with the air passage, at the moment of communication, negative pressure in the air box 4 acts on a first cavity 8 in each spindle rod 2 through the air passage instantly, and acts on a gap between the inner wall of the bobbin and the outer wall of the spindle rod 2 through the through hole 9, and due to the fact that the gap is small, external air cannot enter the gap rapidly to balance the negative pressure, the bobbin can suddenly bear downward pressure under the action of pressure difference between the inner wall and the outer wall, and the action direction of the pressure is perpendicular to the side wall of the bobbin, and the centering effect is achieved; meanwhile, the outer end of the ejector block 11 is at normal pressure, the upper end of the piston 13 is also at normal pressure, so that the piston 13 and the sliding sleeve 16 are located at the lowest position, the inner end of the mounting hole 10 is communicated with the first cavity 8, negative pressure in the first cavity 8 acts on the inner end of the ejector block 11, therefore, the negative pressure in the first cavity 8 can enable the ejector block 11 to move inwards to retract into the mounting hole 10 under the action of the first spring 12, the bobbin is pressed down to the right position under the action of pressure difference, the bobbin gradually enters a gap between the bobbin and the spindle blade 2 along with outside air, the air pressure is balanced, the pressing force disappears, and meanwhile, the ejector block 11 is ejected out under the action of the first spring 12 to press the inner wall of the bobbin to fix the bobbin.

After the bobbin is fixed, the textile equipment can start to work, in the period, the switch valve 7 is closed, high pressure is filled into the air box 4 through the inflator pump 5, when the bobbin needs to be taken down, the switch valve 7 is firstly opened to form a small opening, high-pressure air in the air box 4 partially enters the air passage and the first cavity 8 to push the piston 13 and the sliding sleeve 16 to move upwards, the inner end of the mounting hole 10 is sealed by the sliding sleeve 16, then the switch valve 7 is completely opened, the high pressure in the air box 4 completely acts on the first cavity 8 and enters a gap between the bobbin and the spindle blade 2 through the through hole 9, the bobbin receives upward thrust, meanwhile, the high pressure acts on the outer end of the top block 11 through the vertical groove 26 to push the top block 11 to move slightly inwards, so that the top block 11 loosens the bobbin, the bobbin is ejected upwards under the action of air pressure, and the bobbin can be taken down easily.

After the bobbin is inserted on the spindle blade 2, before the switch valve 7 is opened to switch on the negative pressure, the electromagnet 20 is powered off, the electromagnet 20 pulls the ball 19 downwards in an inclined mode, the ball 19 resets upwards under the action of the second spring 18 after the power off and vibrates, the spindle blade 2 is knocked and vibrated, the bobbin is made to fall in place preliminarily, and the bobbin is prevented from being placed on the spindle blade 2 in an inclined mode.

The device presses the tube by using sudden negative pressure, avoids rigid mechanical contact and stress, can avoid damaging the bobbin and the spindle blade 2, has the centering and centering effect on the bobbin by the direction of the air pressure acting force towards the axis, can quickly complete tube pressing and tube taking actions, has higher working efficiency than mechanical tube pressing, is flexible in spatial arrangement and small in size, can be very easily integrated on textile equipment, and reduces the space occupied by the equipment.
