Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1 and 2.

A creel structure of an automatic yarn spreading machine comprises a creel body 2, a side plate 12, a roller I5, a roller II7, a roller III9 and the like.

The frame body 2 is a rectangular frame, and the rear end of the frame body protrudes upwards, so that the top surface of the frame body is L-shaped, and the raw material tows 4 can be hung conveniently. Preferably, the upper end of the frame body 2 is provided with a clamping groove 16, so that the raw material tows 4 can be clamped into the clamping groove 16 to limit the raw material tows.

The roller I5, the roller II7 and the roller III9 are all cylindrical, are arranged in parallel in sequence from front to back and are tightly attached to each other. The rollers I5 and III9 are respectively erected on the frame body 2. The drum III9 is provided with a gear I14 at one end and is engaged with a driving gear on an output shaft of the motor 11 so as to be driven to rotate by the motor. The motor 11 is arranged on the frame body, is close to the roller III9, and is controlled to start and stop by a control circuit.

The side plate 12 is a long plate, the front end of the side plate is bent downwards and then fixedly connected with the frame body 2, and the rear end of the side plate is suspended and provided with a V-shaped connector 10. The two side plates 12 are symmetrically arranged above the roller I5. The rotating shaft of the roller II7 is erected on the connecting head 10 and is in surface contact transmission with the roller I5. And one end of a rotating shaft of the roller II7 is provided with a gear II15. The gear II15 and the gear I14 on the roller III9 are positioned on the same side and are meshed with each other, the roller II7 can be driven by the roller III9 to rotate, and then the roller I5 is driven by the roller II7 through surface contact to rotate.

The diameter of the roller I5 is smaller than that of the roller II7 and smaller than that of the roller III9, so that the raw material tows can be leveled. Preferably, the diameter of the roller I is 7mm, the diameter of the roller II is 11mm, and the diameter of the roller III is 20mm.

The side plate 12 is inclined upwards, and an included angle between the side plate and the top surface of the frame body 2 is about 45 degrees, so that the roller II7 is better attached to the roller I5 and the roller III9, and the leveling effect on the raw material tows 4 is ensured.

A rack rod I8 is arranged between the suspended ends of the two connectors 10. A rack bar II3 is arranged between the front ends of the two side plates 12. The vertical distance between the rack bar I8 and the roller II7 is about 7 cm, the vertical distance between the rack bar II3 and the roller I5 is about 3 cm, so that the raw material tows 4 span the rack bar I8 and the rack bar II3 and are prevented from contacting the roller I5 and the roller II7.

Also included are leads 6. The lead 6 is in the form of a wire, and both ends of the wire are fixed to the two side plates 12, respectively, and are in a stretched state. The lead 6 is insulated from the side plate 12, and has one end electrically connected to the control circuit and the other end being a blind end. Preferably, the wire 6 is located 1-2cm above the contact surface of the rollers I5 and II7 and parallel to the contact surface, so that the raw material tow 4 is located above the wire 6 and not in contact with the wire during normal operation of the laying apparatus. When wire jamming occurs, the raw material wire bundle falls downward under the action of gravity to touch the lead wire.

The control circuit comprises a switching power supply, a relay and the like. The output anode of the switch power supply is connected with one end of the lead, and the output cathode of the switch power supply is connected with one input end of the relay. The other input end of the relay is connected with the side plate. The relay is normally closed and is connected in series in a motor circuit. When the relay is powered off, the relay is in a closed state, so that a motor circuit is conducted, and the motor runs normally. When the relay is electrified, the relay is in a disconnected state, so that the circuit of the motor is disconnected, and the motor is stopped. Hack lever I and hack lever II with the curb plate is the metal material, has conductivity. The raw material tow also has electrical conductivity. Thus, when the strand of material touches the lead, the relay can be energized to open and the motor can be shut down.

The side of the frame body 2 is provided with a current collection box 13, and a switching power supply, a relay and the like can be arranged in the current collection box 13.

The lower part of the frame body 2 is provided with a wire releasing mechanism 1 which can convey the raw material tows after being arranged to a wire laying machine tool.

When the device runs, the end of the raw material tows is pulled out of the raw material barrel, and then the raw material tows are wound at the bottom of the roller III after being wound around the clamping groove at the upper end of the frame body and then penetrate out of the space between the roller III and the roller II, and then the raw material tows after finishing cross the frame rods I and II, enter the filament placing mechanism below the frame body, and are conveyed to the filament laying machine bed by the filament placing mechanism. After the motor is started, the roller I, the roller II and the roller III are driven to rotate, the raw material tows are pressed between the roller II and the roller III and move forwards along with the rotation of the roller III under the action of friction force, and meanwhile, the raw material tows are leveled and arranged to eliminate twist, fuzzing and the like. At this time, the raw material tow is in a tight state and does not touch the lead wire below the raw material tow. When the problem of yarn clamping occurs, the part of the raw material yarn bundle between the frame rod I and the frame rod II is not tightened any more, and falls downwards under the action of gravity. When the raw material tows touch the lead wires, the lead wires and the side plates form a passage because of the conductivity of the raw material tows, and then the relay is powered on and disconnected, so that the motor is stopped. Thereby, effectively avoided because of raw materials silk bundle pile up and damage and cause the waste of raw materials to can save and arrange the special messenger and monitor, reduced the human cost.

The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
