Description

Technical Field

[0001] The utility model relates to the field of tire production equipment, and more specifically, to an automatic cleaning and recycling device for the rubber foam of the tread cutter of a forming machine. Background Art

[0002] As is well known, in the process of tire production, due to considering the thickness of the rubber compound of the tread material and the process requirements, an ultrasonic cutter is needed to cut the tread material, so as to facilitate winding and fitting on the belt drum. Since the working principle of the ultrasonic cutter is to use high-frequency ultrasonic waves for vibrating cutting, rubber foam will splash during cutting, which is easy to adhere to the cutter plate, resulting in impurities at the cutting joint of the material. In the vulcanization process, the presence of rubber foam impurities will cause incomplete flow of the rubber compound, easily generate bubbles, resulting in defective tires and increasing the additional production cost of tires. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an automatic cleaning and recycling device for the rubber foam of the tread cutter of a forming machine, which realizes the automatic cleaning and recycling of the rubber foam impurities generated at the cutter plate during the cutting of materials.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an automatic cleaning and recycling device for the rubber foam of the tread cutter of a forming machine, which is provided with a cutter tool holder and a tread cutter plate. The feature is that a fixed bracket is fixed on the cutter tool holder, a lifting cylinder device is installed on the fixed bracket, the telescopic rod of the lifting cylinder device is connected with a pneumatic motor, a cleaning brush is connected with the output shaft of the pneumatic motor, an air duct is connected to the lifting cylinder device and the pneumatic motor for providing power for the telescopic movement of the lifting cylinder device and the rotation of the pneumatic motor. A rubber foam recycling device and a vacuum pumping device are installed on the side of the starting end of the tread cutter plate. An initial position photoelectric sensor and a terminal position photoelectric sensor are respectively installed at the starting end and the terminal end of the cutting of the tread cutter plate. The initial position photoelectric sensor and the terminal position photoelectric sensor are connected to the signal input end of the PLC system, and the signal output end of the PLC system is connected to the air source switch and the cylinder magnetic switch of the lifting cylinder device.

[0005] The beneficial effect of the utility model is to realize the automatic cleaning and recycling of the rubber foam impurities generated at the cutter plate during the tread cutting process of the forming machine. It significantly improves the quality of the joint of the tread material, reduces the frequency of defective tires caused by the presence of rubber foam impurities during the vulcanization of tires, and ensures the vulcanization quality of tires. Brief Description of the Drawings

[0006] The following further illustrates the utility model with reference to the drawings and embodiments.

[0007] Figure 1 Structural schematic diagram of the utility model.

[0008] In the figure, there are a fixed bracket 1, a cutter tool holder 2, a lifting cylinder device 3, an air duct 4, a pneumatic motor 5, a cleaning brush 6, a tread cutter blade plate 7, a rubber foam recovery device 8, a vacuum pumping device 9, an end position photoelectric sensor 10, and an initial position photoelectric sensor 11. Detailed implementation mode

[0009] In the figure, the utility model is provided with a cutter tool holder 2 and a tread cutter blade plate 7. The fixed bracket 1 is fixed on the cutter tool holder 2. A lifting cylinder device 3 is installed on the fixed bracket 1. The telescopic rod of the lifting cylinder device 3 is connected with a pneumatic motor 5. The cleaning brush 6 is connected to the output shaft of the pneumatic motor 5. The air duct 4 is connected to the lifting cylinder device 3 and the pneumatic motor 5 to provide power for the telescopic movement of the lifting cylinder device 3 and the rotation of the pneumatic motor 5. A rubber foam recovery device 8 and a vacuum pumping device 9 are installed on the side of the starting end of the tread cutter blade plate 7. An initial position photoelectric sensor 11 and an end position photoelectric sensor 10 are respectively installed at the starting end and the end of the cutting of the tread cutter blade plate 7. The initial position photoelectric sensor 11 and the end position photoelectric sensor 10 are connected to the signal input end of the PLC system. The signal output end of the LC system is connected to the air source switch and the cylinder magnetic switch of the lifting cylinder device 3.

[0010] After the tread cutter finishes cutting the material, the end position photoelectric sensor 10 is triggered. The photoelectric signal is transmitted to the air source switch and the cylinder magnetic switch through the PLC system. The air duct 4 is used to ventilate to start the cleaning brush 6 on the pneumatic motor 5 to achieve automatic rotation. At the same time, the lifting cylinder device 3 is started, and its telescopic rod extends downward to lower the cleaning brush 6 to the tread cutter blade plate 7. During the process of the cutter automatically returning to the starting end, the cleaning brush 6 is used to automatically clean the rubber foam impurities at the tread cutter blade plate 7. The rubber foam impurities are swept and collected into the rubber foam recovery device 8 by the cleaning brush 6. When the tread cutter returns to the initial end and triggers the initial position photoelectric sensor 11, the photoelectric signal is transmitted to the air source switch and the cylinder magnetic switch through the PLC system. The pneumatic motor 5 is turned off, and the cleaning brush 6 automatically stops rotating. At the same time, the lifting cylinder device 3 drives the cleaning brush 6 to rise. At the same time, the vacuum pumping device 9 is used to evacuate and recover the rubber foam impurities, realizing the full automation of the cleaning, collection, and evacuation of the cutting rubber foam.
