When the fiber filament bundle is entangled in the roller, the jackscrew induction mechanism 2 senses the condition of the fiber entangled in the roller and is pressed down, the jackscrew induction mechanism 2 transmits signals to the PLC control unit, the PLC control unit controls the shredding mechanism 3 to automatically reciprocate along the axial direction of the drafting roller for shredding operation, the fiber entangled in the roller can be automatically processed, shutdown is not needed, the automation degree of fiber production is improved, the production period is ensured, manual processing is not needed, and the risk of injury and death caused by improper entanglement of manual operation is avoided.
Specifically, the yarn guiding position comprises annular yarn guiding grooves 12 arranged along the circumferential direction of the hollow roller 1, and each yarn guiding groove 12 is used for containing a certain amount of fiber tows, so that the directional drafting of the fiber tows is realized. The hollow roller 1 is provided with a strip-shaped opening 13 communicated with the inner cavity 11 along the axial direction of the hollow roller, and a shredding position is formed at the strip-shaped opening 13 where the yarn guide groove 12 is positioned, so that the yarn cutting mechanism 3 can cut off fiber tows wound on the roller at the shredding position in the process of reciprocating movement along the axial direction of the hollow roller 1.
Specifically, the jackscrew induction mechanism 2 comprises pneumatic ejector rods 21 arranged on two sides of the strip-shaped opening 13 where the wire guide groove 12 is located, induction components 22 for inducing fiber winding rollers are arranged on the pneumatic ejector rods 21, an electric control pressure release valve 23 is arranged in a gas path of the pneumatic ejector rods 21, and the induction components 22 are connected with an alarm unit, the wire cutting mechanism 3 and the electric control pressure release valve 23 through a PLC control unit. When the fiber tows are wound on the rollers, the pneumatic ejector rod 21 is extruded, the fiber tows are pressed down after the bearing capacity of the pneumatic ejector rod 21 is exceeded, so that the sensing component 22 is triggered, the sensing component 22 sends out a signal of the fiber winding rollers to the PLC control unit, the PLC control unit controls the alarm unit to carry out audible and visual alarm to remind workers of winding rollers, meanwhile, the electric control pressure release valve 23 is controlled to release pressure, the pneumatic ejector rod 21 is retracted, then the shredding mechanism 3 is controlled to act for automatic shredding operation, after the pneumatic ejector rod 21 is retracted, the phenomenon that the fiber tows of the winding rollers can jack up the fiber tows which are not thoroughly cut because of pressure reduction after the shredding mechanism 3 cuts off a plurality of filaments is avoided, and the fiber tows of the winding rollers can be thoroughly cut off.

The plunger is used for adjusting the compression degree of the air column, and the air volume in the air cushion is changed through up-and-down movement. A valve is also provided in the pneumatic ram 21 for controlling the inflow and outflow of air in the air cushion to regulate and control the movement of the piston rod 212. When the piston rod 212 is compressed, the gas is compressed and stored in the air cushion, and when the external force is reduced or eliminated, the gas in the air cushion is released outwards, and the piston rod 212 is automatically restored. Can be automatically adjusted according to external stress. When the electric control pressure release valve 23 is arranged in the air path of the pneumatic ejector rod 21, the air in the air cushion can be leaked when the electric control pressure release valve 23 releases pressure, so that the piston rod 212 is retracted stably, and the complete cutting of fiber tows of the winding roller is ensured.

When the fiber is entangled, namely, a plurality of bundles of fibers are wound and overlapped, so that the winding force is larger and larger, namely, the pressure on the head of the piston rod 212 of the pneumatic ejector rod 21 is larger and larger, the piston rod 212 is compressed, at the moment, the contact block 222 touches the travel switch I221 to trigger the travel switch I221, the shredding cutter wheel 333 for shredding on the shredding mechanism 3 contacts the fiber tow of the entangled roll, the travel switch I221 sends an entangled roll signal to the PLC control unit, the PLC control unit controls the alarm unit to carry out audible and visual alarm to remind a worker of entangled roll, and simultaneously controls the electric control pressure release valve 23 to release pressure, so that the pneumatic ejector rod 21 is retracted, and then the shredding mechanism 3 is controlled to reciprocate along the axial direction of the hollow roll 1 to cut off the fiber tow of the entangled roll.
Specifically, the shredding mechanism 3 comprises a reciprocating mechanism fixed along the axial direction of the hollow roller 1 and a shredding component 33 connected with the reciprocating mechanism in a guiding way, and the reciprocating mechanism comprises a transmission mechanism 31 and a guiding sliding component 32 fixed along the axial direction of the hollow roller 1. The transmission mechanism 31 is provided as a belt transmission mechanism 31 or a chain transmission mechanism 31, and is driven to rotate by a transmission motor 311. The guide sliding member 32 includes two guide shafts 321 fixed to both ends of the hollow roller 1 in the axial direction of the hollow shaft. The shredding component 33 comprises a mounting seat 331 which is slidably connected to the two guide shafts 321, a shredding cutter wheel 333 is rotatably connected to the mounting seat 331 through a driving motor 332, the bottom of the mounting seat 331 is fixed to a conveyor belt or a conveyor chain of the transmission mechanism 31, and the middle of the mounting seat 331 is slidably connected to the two guide shafts 321. The transmission mechanism 31 can drive the installation seat 331 to move along the axial direction of the two guide shafts 321, and meanwhile, the driving motor 332 can drive the shredding cutter wheel 333 to rotate, so that fiber tows wound on the rollers can be cut along the axial direction of the hollow roller 1. In addition, in the normal process of drawing the fiber, the top end of the shredding cutter wheel 333 is located below the top end of the jackscrew induction mechanism 2, so that the shredding mechanism 3 is guaranteed to be located at a distance above the shredding cutter wheel 333 in the process of shredding, the normally drawn fiber tow can not be cut off, and only the fiber tow of the winding roller (i.e. the fiber tow contacted with the shredding cutter wheel 333 or the fiber tow extruded by the pneumatic ejector rod 21 to enable the piston rod 212 to shrink and trigger the travel switch I221 to act) is cut off.
And two ends of one guide shaft 321 are respectively provided with a travel switch II 322, and the two travel switches II 322 are connected with the transmission mechanism 31 through the PLC control unit to realize reciprocating movement shredding of the shredding component 33. When the installation seat 331 moves along the axial direction of the two guide shafts 321 to contact one of the travel switches ii 322 and trigger the travel switch ii, the PLC control unit controls the driving motor 311 of the driving mechanism 31 to rotate reversely, so that the installation seat 331 moves reversely until contacting the other travel switch ii 322 and triggering the travel switch ii, and a shredding action is completed. Because the electrically controlled pressure release valve 23 is in a pressure release state during the shredding operation, the pneumatic ejector rod 21 is retracted, and an operator is required to observe whether the reciprocating shredding operation completely cuts off the fiber tows of the winding roller on site. When the operator confirms that the fiber tows of the winding roller are completely cut off, the upper computer or the control key is manually operated to give a control instruction to the PLC control unit, so that the PLC control unit controls the transmission motor 311 of the transmission mechanism 31 to stop rotating, then controls the electric control relief valve 23 to be closed, and controls the retracted pneumatic ejector rods 21 in all the jackscrew sensing mechanisms 2 to extend and reset.
Specifically, a negative pressure filament suction device 4 is arranged below or above the hollow roller 1, the sensing component 22 is connected with the negative pressure filament suction device 4 through a PLC control unit, and when a fiber winding phenomenon occurs, the PLC control unit controls the negative pressure filament suction device 4 to act, so that the fiber tows cut by the filament cutting mechanism 3 are sucked in a negative pressure manner, and the roller surface of the hollow roller 1 can be cleaned effectively.
The negative pressure yarn sucking device 4 comprises a yarn sucking cover 41 arranged below or above the hollow roller 1, a yarn sucking opening 42 opposite to the corresponding yarn guiding groove 12 is formed in one side, close to the hollow roller 1, of the yarn sucking cover 41, the other side of the yarn sucking cover 41 is connected with a negative pressure vacuum pump 44 through a pipeline 43, and the yarn sucking opening 42 enables yarn sucking to be more accurate. The wire suction covers 41 at the positions of the plurality of hollow rollers 1 can be connected with the main pipeline after being connected through the branch pipes and then connected with the negative pressure vacuum pump 44, so that the negative pressure wire suction cleaning of the plurality of hollow rollers 1 can be realized by one negative pressure vacuum pump 44.
The invention also provides a fiber online shredding and winding-preventing method, which uses the fiber online shredding and winding-preventing device and comprises the following steps:
step 1: the fiber tows are guided and pulled on the plurality of hollow rolls 1 such that a fixed amount of fiber tows is located in each of the yarn guide grooves 12 of the hollow rolls 1.
Step 2: when the winding phenomenon occurs, the pneumatic ejector rod 21 of the corresponding jackscrew induction mechanism 2 is pressed down to retract and induce the winding action, and then the filament cutting mechanism 3 moves back and forth along the axial direction of the hollow roller 1 to automatically cut the fiber of the winding roller, and simultaneously negative pressure adsorption cleaning is carried out on the cut broken filament.
Specifically, when the winding phenomenon occurs, that is, the plurality of fibers are wound and overlapped, the winding force is increased, that is, the pressure on the head of the piston rod 212 of the pneumatic mandrel 21 is increased, the piston rod 212 is compressed, at this time, the contact block 222 touches the travel switch i 221 to trigger the travel switch i 221, and at the same time, the cutter wheel 333 for cutting the fibers on the cutting mechanism 3 touches the fiber bundles of the winding roller.
The travel switch I221 sends a winding roller signal to the PLC control unit, the PLC control unit controls the alarm unit to carry out audible and visual alarm to remind a worker of winding rollers, simultaneously controls the electric control pressure release valve 23 to release pressure, enables the pneumatic ejector rod 21 to retract, then controls the driving motor 332 to act to enable the shredding cutter wheel 333 to rotate, and simultaneously controls the driving motor 311 to act, so that the driving mechanism 31 drives the mounting seat 331 to move along the two guide shafts 321, and enables the shredding cutter wheel 333 to rotate to cut fiber tows of the winding rollers;
when the installation seat 331 contacts one of the travel switches ii 322 and triggers it, the PLC control unit controls the driving motor 311 of the driving mechanism 31 to reverse, so as to move the installation seat 331 in the opposite direction, until the other travel switch ii 322 contacts and triggers it, and then completes a shredding operation. Because the electrically controlled pressure release valve 23 is in a pressure release state during the shredding operation, the pneumatic ejector rod 21 is retracted, and an operator is required to observe whether the reciprocating shredding operation completely cuts off the fiber tows of the winding roller on site.
Step 3: after the shredding operation is completed, the pneumatic ejector rod 21 in the jackscrew induction mechanism 2 is reset.
When the operator confirms that the fiber tows of the winding roller are completely cut off, the upper computer or the control key is manually operated to give a control instruction to the PLC control unit, so that the PLC control unit controls the transmission motor 311 of the transmission mechanism 31 to stop rotating, namely the shredding action is finished, then the electric control pressure release valve 23 is controlled to be closed, and the retracted pneumatic ejector rods 21 in all the jackscrew sensing mechanisms 2 are controlled to extend and reset. The cut fiber bundles are then manually drawn off and rewound on a drawing roll set.
In summary, the invention can automatically treat the phenomenon of fiber winding without stopping, improves the automation degree of fiber production, ensures the production period, does not need manual treatment, and avoids the risk of injury and death caused by improper manual operation.
The foregoing is provided by way of illustration of the principles of the present invention, and is not intended to be limited to the specific constructions and applications illustrated herein, but rather to all modifications and equivalents which may be utilized as fall within the scope of the invention as defined in the claims.
