When the small-sized tubular bottles are produced in a switching mode, the height of the small-sized tubular bottles at the detection station is reduced more than that of the tubular bottles of the feeding conveying device and the blanking conveying device, so that the height of the small-sized tubular bottles at the detection station and that of the tubular bottles of the feeding conveying device and the blanking conveying device can be kept at the same height, the heights of the first roller 110 and the second roller 120 can be adjusted by lifting the lifting adjusting mechanism, the height of the small-sized tubular bottles placed between the first roller 110 and the second roller 120 can be supported to rise, and the height of the small-sized tubular bottles after the switching mode can be consistent with that of the feeding conveying device and the blanking conveying device.

When the large-size tubular bottles are produced in a transfer mode, the height of the tubular bottles at the detection station is higher than that of the tubular bottles of the feeding conveying device and the blanking conveying device, so that the height of the tubular bottles at the detection station and that of the tubular bottles of the feeding conveying device and the blanking conveying device can be kept at the same height, the heights of the first roller 110 and the second roller 120 can be adjusted through descending of the lifting adjusting mechanism, the height of the tubular bottles supported and placed between the first roller 110 and the second roller 120 is further reduced, and the height of the large-size tubular bottles after the transfer mode can be consistent with that of the feeding conveying device and that of the blanking conveying device.

The lifting adjusting mechanism may include a base 100 and a moving base 130, wherein the moving base 130 is disposed on the base 100 and can be adjusted to lift and move; the number of setting up of removing seat 130 can be one, and first gyro wheel 110 and second gyro wheel 120 all set up on removing seat 130 to can carry out synchronous lift adjustment to the height of first gyro wheel 110 and second gyro wheel 120 at removing seat 130 lift removal in-process, make the regulation of detection station more convenient, swift.

Of course, the number of the movable bases 130 may also be two, the first roller 110 is disposed on one movable base 130, and the second roller 120 is disposed on the other movable base 130, so that the height of the first roller 110 and the height of the second roller 120 can be adjusted by the lifting movement of the two movable bases 130, but in this way, in order to ensure that the relative heights of the first roller 110 and the second roller 120 are not changed, higher adjustment operation precision is required.

Specifically, as shown in fig. 3, the base 100 is provided with a lifting assembly, and the movable base 130 is disposed on the lifting assembly, so that the lifting movement of the movable base 130 is controlled by the lifting assembly; wherein the lifting assembly may be a scissor lift assembly 102 such that the lowering movement adjustment of the movable base 130 is achieved by a rotational folding of two scissor arms of the scissor lift assembly 102 and the raising movement adjustment of the movable base 130 is achieved by a rotational opening of two scissor arms of the scissor lift assembly 102.
