The movable plate 3 is located below the fixed plate 4 and is always located below the fixed plate 4 during the movement to be close to or far from the fixed plate 4 so as to realize the approaching and merging between the driving roller 8 and the driven roller 9.

The driving component 5 drives the movable plate 3 to slide along the upright post 2; in this embodiment, the driving unit 5 is fixed on the upper portion of the fixed plate 4, the driving rod 6 of the driving unit 5 is fixedly connected to the movable plate 3 after passing through the fixed plate 4, and the driving unit 5 is a cylinder, the opening and closing of which is not shown in the air source diagram, and the movable plate 3 is driven to move up and down when the cylinder is operated. Of course, a linear bearing (not shown) is provided between the movable plate 3 and the column 2 for smooth sliding and friction reduction, thereby improving the precision of the movement.

A driving roller 8 is arranged on one side surface of the fixed plate 4, a driven roller 9 is arranged on the same side surface of the movable plate 3, and the driving roller 8 and the driven roller 9 are sleeved with rubber rings and expand the rubber rings. In the embodiment, the driving roller 8 and the driven roller 9 are rotatably coupled to the movable plate 3 through bushings (not shown), respectively, except that the driving roller 8 is connected to the driving motor 7 after traversing the movable plate 4, and the driven roller 9 does not traverse the movable plate 3 as a driven roller of the driving roller 8. Still include driving motor 7, driving motor 7 is fixed in the one side of deciding board 4 and keeping away from initiative cylinder 8, and initiative cylinder 8 passes behind deciding board 4 through the bush and is connected with driving motor 7 for driving motor 7 drive initiative cylinder 8 rotates, and after the installation rubber ring, initiative cylinder 8 drives driven cylinder 9 synchronous rotation, thereby makes the rubber ring carry out synchronous rotation.

As shown in fig. 2, in the embodiment, the driven roller 9 and the driving roller 8 are arranged in parallel, and have the same diameter, and the two are arranged in parallel to ensure the synchronism of the movement, so as to drive the rubber ring to rotate synchronously when measuring the rubber ring, if the rubber ring has a horn-shaped defect, the small horn-shaped defect is not easy to be found artificially, and the rubber ring can obviously present a horn shape in the rotating process of the roller, so that the defect can be obviously seen, the poor flatness of the rubber ring is indicated, and the rubber ring is removed in time. The two are the same in diameter, efficiency can be improved when the large-scale rubber ring is measured, compared with the technology that only a small-scale rubber ring can be measured in the prior art, the method and the device for measuring the large-scale rubber ring provide convenience for measuring the large-scale rubber ring, and can detect horn-shaped defective products.

The rubber ring rolling machine further comprises a display screen 10, which is arranged on the upper side surface of the fixed plate 4 and is used for displaying the data of the inner perimeter of the rubber ring, specifically, in the embodiment, the diameters of the driven roller 9 and the driving roller 8 are the same and are arranged in parallel, as shown in fig. 4, the inner perimeter of the rubber ring is calculated as: in the case of the rubber ring being stretched, 2 times the distance between the driven roller 9 and the axial core of the driving roller 8 + half of the circumference of the driven roller 9 + half of the circumference of the driving roller 8, i.e., x1 × 2+ pi R1 × 2, the inner circumference is calculated and divided by pi to calculate the inner diameter of the rubber ring. In this process, the distance between the two mandrels can be measured by a sensor, such as a distance sensor or the like. The driven roller 9 and the driving roller 8 are driven by the driving component 5 to be away from each other and to prop open the rubber ring, before the rubber ring is used, the pressure of the driving component 5, namely the air cylinder, is set to be a fixed value, the fixed value of the pressure is smaller than the tension of a tension line in the rubber ring (to prevent the rubber ring from being broken), meanwhile, the rubber ring can be completely propped open without damaging the rubber ring, when the air cylinder drives the movable plate 3 to move downwards, the driven roller 9 moves downwards to prop open the rubber ring, the force of the rubber ring when the driven roller 9 props open the rubber ring, namely, the resistance force received by the movable plate 3 in the downward direction (the friction force between the movable plate and the upright post is ignored) and the pressure received when the driving rod 6 of the air cylinder extends out, when the force reaches the set pressure fixed value, the air cylinder stops moving, the fixed distance is kept between the driven roller 9 and the driving roller 8, at the moment, the rubber ring is completely propped open, the displayed inner circumference data is not changed any more at this time, and is used as the final inner circumference data of the rubber ring.

The working principle is as follows:

in the initial state, the driven roller 9 and the driving roller 8 are close to each other.

Placing a large rubber ring on the two rollers, starting the driving motor 7 to enable the driving roller to rotate, starting the air cylinder to enable the driving rod 6 to extend out, enabling the movable plate 3 to move downwards and the driven roller 9 to move downwards so as to prop open the rubber ring, driving the driven roller 9 to rotate in the gradual propping process of the rubber ring, and detecting the horn-shaped defect through the rotation of the rubber ring when the two rollers rotate; if there is no horn defect, the rubber ring rotates continuously, the display screen 10 displays the real-time inner perimeter, when the real-time pressure on the driving rod 6 reaches the pressure fixed value when the cylinder operates, the cylinder stops moving, the roller rotates continuously, at this moment, the perimeter on the display screen is the actual perimeter, and the inner diameter can be calculated.

Example 2:

as shown in fig. 5, the driving roller 8 is provided with a plurality of annular grooves in the circumferential direction. The annular groove can lead air to flow by a certain gap existing when the rubber ring is contacted with the driving roller 8, improves the smoothness of the rotation of the rubber ring, improves the precision of a detection result, and does not damage the rubber ring.

Example 3:

as shown in fig. 2, a rolling screen 11 is fixed to the front side of the movable plate 3, and the lower side of the rolling screen 11 is placed on the platen 1. The rolling shutter 11 is transparent and adapted to be lifted and lowered in response to the lifting and lowering of the movable plate 3, and is adapted to be stopped when other devices are installed between the vertical posts to prevent dust from being accumulated, damaged, and the like.
