The distance between the two guide rollers 215 is greater than the distance between the front roller 302 and the rear roller 402. The diameter of the guide wheel 215 is larger than the diameter of the pinch wheel 216.
One guide roller 215 is positioned above the front conveyor unit 300 and guides the tire film to be measured to move onto the plurality of rollers 12, and the other guide roller 215 is positioned above the rear conveyor unit 400 so that the tire film on the rollers 12 can be better moved onto the rear conveyor unit 400.
The belt 217 is fitted over the top pulley 214 and the two guide pulleys 215, while the inner surface of the belt is in contact with the plurality of pressing pulleys 216.
The top pulley 214 and the two guide pulleys 215 form a triangular structure, and the tightness of the belt 217 can be adjusted by adjusting the installation height of the top pulley 214. In addition, the diameter of the guide wheel 215 is larger than that of the pressing wheel 216, and the diameter difference between the two provides a space for installing the tension wheel.
The main driving wheel is sleeved on the front roller 302 of the front conveying unit 300, the front roller 302 serves as a driving part to provide power for the main driving wheel, and the main driving wheel and the front roller rotate synchronously. The surface of the main driving wheel is provided with an ethylene propylene diene monomer rubber layer which increases friction when contacting with the belt 217.

One end of the swing arm 2193 away from the metal cylinder 2191 is fixedly connected with the tension wheel 218.
The tensioner 218 tightens the belt 217 using its own weight, and since the rubber column 2192 is movably connected to the swing arm 2193, when the belt 217 is tight, the tightening force is large and the tensioner 218 is slightly lifted up, and when the belt 217 is loose, the tightening force is small and the tensioner 218 slightly falls down to press the belt 217. Therefore, the tension pulley 218 and the elastic tension member 219 cooperate to adjust the tension of the belt 217.
When the front end of the tire film just contacts the first roller 12, the photoelectric sensor 220 transmits an entering displacement signal to the controller, and the controller receives the entering displacement signal and controls the roller driving device 200 to descend until the outer surface of the belt 217 contacts with the main driving wheel on the front roller 302, the rear roller 402 and the rollers 12.
At this time, if every two rollers 12 are divided into one group, a pressing wheel 216 is pressed on a portion between the two rollers of each group, the pressing wheel 216 presses the belt 217, so that the belt 217 presses the rollers 12, and therefore, the belt 217 is synchronously rotated by the driving of the main driving wheel, thereby driving the rollers 12 to rotate around their own axes. The unpowered roller 12 becomes a powered roller to drive the tire film thereon to move forward smoothly, and the guide wheel 215 of the front conveying unit 300 presses the tire film on the front conveying unit 300 to assist the tire film to move through the area of the roller 12 smoothly.
When the front end of the tire rubber sheet enters the first rear receiving roller 403 of the rear conveying unit 400, the photosensor 220 transmits a departing displacement signal to the controller, and the controller receives the departing displacement signal and controls the roller driving device 200 to ascend and leave the roller 12, so that no additional pressure is generated on the detection scale 100. Since the tire rubber sheet can smoothly pass through the detection scale 100 under the power driving of the front and rear conveying units 300 and 400, the detection scale 100 normally operates to weigh the tire rubber sheet passing therethrough on line during the whole extrusion process.
