Description

Technical Field

[0001] The utility model relates to the field of tire production equipment, in particular to a device for automatically pressing tail material of an extrusion auxiliary line. Background Art

[0002] As we all know, in the tire production process, the tread needs to be stored in the storage pit before cutting, and then transported to the cutting conveyor belt according to a fixed length. The storage pit is a 45° downhill conveyor belt that transfers the tread. The contact surface between the tread and the conveyor belt is covered with plastic paper, which is very smooth. During the tread finishing process, the tread will slide into the storage pit without subsequent tread tension, and the remaining tailings will stick or accumulate. Therefore, manual assistance is required during the finishing process to prevent the tread from sliding into the storage pit. There are major disadvantages in this production operation. First, when the operator manually pulls the tread, there is a great safety hazard; second, a special person is required to watch over it during the finishing. If the watch is not timely, the tread will slide into the storage pit in an instant; third, the consumption of raw materials increases, and the tread sliding off the storage material will cause adhesion, resulting in waste and defective treads. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a device for automatically pressing tail material of an extrusion auxiliary line, which changes the previous mode of manual assistance, reduces raw material consumption, and improves operation safety.

[0004] The utility model adopts the following technical scheme to solve the technical problem: an automatic tail material pressing device for an extrusion auxiliary line is provided, the device is provided with a material storage pit, a cutting knife conveyor belt is horizontally installed on one side of the material storage pit, and a downhill conveyor belt is obliquely installed on the other side of the material storage pit. The utility model is characterized in that a pressure roller cylinder is hinged on a bracket of the downhill conveyor belt, the pressure roller cylinder is controlled by a pressure roller solenoid valve, the cylinder rod end of the pressure roller cylinder is hinged with the middle part of the pressure rod, a pressure roller is installed on one end of the pressure rod via a rotating shaft, and the other end of the pressure rod is hinged with the bracket, a drying conveying roller is horizontally installed above the downhill conveyor belt, a free flower roller is installed at the rear end of the drying conveying roller via a roller shaft, a material tracking proximity switch is installed at the rear end of the free flower roller, an automatic button and a stop button are installed on the bracket, the automatic button, the stop button and the material tracking proximity switch are connected to the signal input end of a PLC controller, and the signal output end of the PLC controller controls the pressure roller solenoid valve, the cutting knife conveyor belt, the start of the downhill conveyor belt and the start of the drying conveying roller.

[0005] The beneficial effects of the utility model are that the automation of tailings can be achieved without human intervention, the overall automation level of the equipment can be improved, the labor intensity and safety of operators can be effectively reduced, the probability of equipment causing safety hazards to operators can be reduced, tread waste and defective products can be reduced, and raw material consumption can be reduced.

DETAILED DESCRIPTION

[0009] In the figure, the utility model is provided with a storage pit 6, a cutter conveyor belt 10 is horizontally installed on one side of the storage pit 6, a downhill conveyor belt 5 is obliquely installed on the other side of the storage pit 6, a pressure roller cylinder 9 is hinged on the bracket of the downhill conveyor belt 5, the pressure roller cylinder 9 is controlled by a pressure roller solenoid valve 12, the cylinder rod end of the pressure roller cylinder 9 is hinged to the middle of the pressure rod, a pressure roller 4 is installed on one end of the pressure rod via a rotating shaft, and the other end of the pressure rod is hinged to the bracket, a drying conveyor roller 2 is horizontally installed above the downhill conveyor belt 5, a free flower roller 11 is installed at the rear end of the drying conveyor roller 2 via a roller shaft, and a material tracking proximity switch 1 is installed at the rear end of the free flower roller 11, and an automatic button 7 and a stop button 8 are installed on the bracket, and the automatic button 7, the stop button 8, and the material tracking proximity switch 1 are connected to the signal input end of the PLC controller, and the signal output end of the PLC controller controls the pressure roller solenoid valve 12, the cutter conveyor belt 10, the downhill conveyor belt 5 and the drying conveyor roller 2.

[0010] After the equipment is started, the drying conveyor roller 2 and the downhill conveyor belt 5 are started, and the automatic button 7 is pressed. After the tread 3 passes through the free flower roller 11, the free flower roller 11 stops rotating, and the material tracking proximity switch 1 is in the 24V or 0V state. The PLC controller determines that the tread 3 will pass through the drying conveyor roller 2 immediately, and the PLC controller outputs a signal to the pressure roller solenoid valve 12. The pressure roller solenoid valve 12 controls the pressure roller 4 to be pressed down through the pressure roller cylinder 9. The tread 3 is transmitted to the storage pit 6 according to the speed of the downhill conveyor belt 5. The tread 3 in the storage pit 6 is transmitted to the cutter through the cutter conveyor belt 10 for cutting.

[0011] The new tread is transferred to the position of the free flower roller 11, the free flower roller 11 rotates, the material tracking proximity switch 1 sends 24V and 0V alternately to the PLC controller, the PLC controller determines that the tread will soon reach the drying conveying roller 2, the PLC controller outputs a signal to the pressure roller solenoid valve 12, and the pressure roller solenoid valve 12 controls the pressure roller 4 to lift through the pressure roller cylinder 9. If automatic operation is not required, press the stop button 8 to cancel the automatic tail material pressing device.
