[0024] The height micro-adjustment device is composed of the inclined surfaces of the lower wedge block 23 and the upper wedge block 24, the lower wedge block 23 is connected to the box body 1; the middle of the upper wedge block 24 is provided with a horizontally arranged thread, the lead screw 25 is threadedly matched with the upper wedge block 24, the two ends of the lead screw 25 are supported and connected by the limit bearing seat 27, and one end of the lead screw 25 is connected to the hand wheel 26; the top surface of the upper wedge block 24 is a horizontal plane and contacts the lower surface of the upper platform 28, the upper surface of the upper platform 28 supports the lower bearing seat 21; the two ends of the upper platform 28 are connected to the limit bearing seat 27. The servo motor 19, the lower bearing seat 21, the lower pressure wheel 7 and the upper platform 28 form an integral body and can move along the slide rail 22. When the hand wheel 26 drives the lead screw 25 to rotate, the rotational power of the lead screw is transmitted to the upper wedge block 24 and converted into a linear motion of the upper wedge block 24, thereby supporting the upper platform 28 to move up or down, and the gap adjustment of the upper pressure wheel 6 and the lower pressure wheel 7 can be realized.

[0025] In order to eliminate the matching clearance between the upper wedge block 24 and the lead screw 25, a groove is provided at the matching position of the upper wedge block 24 and the lead screw 25, and a spring 29 is provided in the groove. One end of the spring 29 presses against the inner end surface of the groove, and the other end contacts the bearing end surface for limiting position.

[0026] The outer circular section of the upper pressing wheel 6 is a convex arc, and the upper pressing wheel 6 is in rolling contact with the inner surface of the weld of the steel drum; the outer edge section of the lower pressing wheel 7 is a concave arc, and the lower pressing wheel 7 is in rolling contact with the outer surface of the weld of the steel drum.

[0027] A plurality of barrel supporting wheels 3 arranged in a straight line are symmetrically arranged on both sides of the U-shaped opening, and the barrel supporting wheels 3 are in contact with the outer circumference of the steel barrel for support. The barrel supporting wheels 3 cooperate with the upper pressing wheel 6 and the lower pressing wheel 7 to support the steel barrel.
