The tread of a tire is one of the most important components in the tire and is also the heaviest component in the tire, accounting for about 30% of the total weight of the tire, and therefore, the quality of the tread component semifinished product also directly affects the quality of the finished tire product. As the market demand for tire quality increases, tire manufacturers place more and more emphasis on quality control of tread semi-finished products.
At present, conventional tread semi-finished products are continuously extruded and produced by adopting an extruder, and tread products are cut to length on line. Referring to fig. 1, the tread of the truck tire is required to be cut according to a standard length, and the length of the cut single tread is about 3m. The current tread cutting fixed-length conveying device comprises a downhill conveying belt 1, a storage pocket 7 and a cutting conveying belt 4 which are sequentially arranged along the specified conveying direction of the tread; the inner wall of the material storage pocket 7 is provided with a potential detecting device 8; a tread roller 5 and a cutting device 6 are arranged at the end side of the cutting conveyor belt 4 far away from the storage pocket 7. The cutting specific process of the single tread comprises the following steps: the tire 2 to be cut is conveyed in place through the cutting conveying belt 4 and then is stopped, at the moment, the tire tread pressing roller 5 presses down the tire tread 2, and the tire tread cutting device 6 transversely moves the cutting knife to complete cutting of the tire tread 2; when the cutting device 6 moves the cutter transversely and returns to the initial position, the tread pressing roller 5 is lifted, the fixed-length conveying of the cutting conveying belt 4 is started again, and the next circulation action is repeated. In the process, the conveyor belt 4 is in a stop waiting state in each cutting process of the cutter, and the tread production line is always in a continuous extrusion tread production state; therefore, in order to ensure continuous production of the tread production line, the tread cutting fixed-length conveying device is provided with a storage pocket 7 for temporarily storing the tread, namely, when the tread is cut by the cutting device 6, the cutting conveying belt 4 is in a stop state, the tread conveyed from the side of the production line firstly falls into the storage pocket 7 to be stored through the downhill conveying belt 4, and after the conveying of the cutting conveying belt 4 is restored, the tread enters the cutting conveying belt 4 from the storage pocket 7 and is conveyed to the tread cutting device 6 to be cut; the photoelectric position detection device 8 is arranged at the end side of the cutting conveyer belt 4 close to the material storage pocket 7 and is used for detecting the tread storage position, so that the conveying speed of the cutting conveyer belt 4 is adjusted according to the position signal fed back by the photoelectric position detection device 8, namely, the conveying speed of the cutting conveyer belt 4 is faster as the tread storage amount is larger.
However, in the conventional tread cutting and fixed-length conveying device, the depth of the storage pocket 7 is about 1.2m, and the height difference between the bottom of the storage pocket 7 and the cutting conveyor belt 8 is about 1.8m, so that the length of the tread in the storage pocket 7 can reach 2.5m, and the weight of the tread with a slightly larger specification can reach about 20 kg; therefore, when the cutting conveyor belt 4 is started, the skid phenomenon exists between the tread and the cutting conveyor belt 4 due to the influence of the weight of the stored tread, so that the speeds of the tread and the cutting conveyor belt 4 are not synchronous, and the accuracy of the tread fixed-length conveying is affected; the tread that is located in the storage pocket 7 still can lead to the tread to have tensile deformation because of the influence of dead weight, also can directly influence the accuracy that the tread fixed length was carried, causes the tread to cut the precision of length relatively poor, also can influence quality and the qualification rate of single tread simultaneously.
