In order to achieve the above effect, the number of the wheel arms 54 is at least three, and the wheel arms are distributed in an annular array around the wheel shaft 53, preferably five in the embodiment, and at least two groups of the wheel arms 54 and the pressing plates 55 can be always kept in the pressing bin 51 at the same time, so that the downward pressure of the pressing bin on the bamboo tube is more continuous and stable, and the connection effect of pressing and pressing adjacent pressing plates 55 is better.

When the pressing plate 55 is fixed to the wheel arm 54, the length of the pressing plate 55 beyond the wheel arm 54 is limited, specifically, when the wheel arm 54 is horizontal, the pressing plate 55 cannot abut against the inner wall of the pressing bin 51 relative to the side groove 52, otherwise, the pressing plate can be clamped, so that only at the position, the pressing plate 55 is in full contact with all bamboo tubes in the same plane, and partial bamboo tubes on the upper side, especially the lower side, cannot be pressed, and further the extrusion effect is poor.

Therefore, in the present embodiment, the pressure plate 55 is disposed to be hinged to the wheel arm 54, and further, a slide block 551 and a slide rail 552 are disposed on the pressure plate 55, the slide rail 552 is fixedly disposed on the pressure plate 55, the slide block 551 is slidably connected to the slide rail 552, and the slide block 551 is hinged to the wheel arm 54, wherein the rotation direction of the hinge is referred to b direction shown in fig. 3, and the direction of the sliding connection is referred to c direction shown in fig. 3; with this arrangement, when the wheel arm 54 is at a high point, the pressing plate 55 slides downward due to gravity, and the radius of rotation is reduced, so that the pressing plate does not interfere with the inner wall of the pressing chamber 51 after entering the pressing chamber 51 and before rotating to a horizontal position.

When the wheel arm 54 rotates from the upper side position to the horizontal position, the pressure of the tail end of the wheel arm 54 on the inner side (right side in fig. 3) of the pressing plate 55 gradually drives the pressing plate 55 to tend to be horizontal, so as to provide uniform pressure and extrude the bamboo tube on the lower side to be in a flush state;

then, in the process that the wheel arm 54 rotates downwards from the horizontal position, the pressing plate 55 can be fully pressed on all the bamboo tubes below, the inner end (right end) of the pressing plate 55 is kept close to the inner wall of the pressing bin 51, the wheel arm 54 can slide outwards (leftwards in fig. 3) relative to the pressing plate 55, the pressing plate 55 is kept to be pressed downwards in a horizontal direction, the bamboo tubes close to the inner side are prevented from being subjected to no pressure, and then the wheel arm 54 moves out of the side groove 52 firstly, and then the pressing plate 55 is driven to be pulled out transversely in a horizontal direction.

It is to be added that, when the pressing plate 55 enters the pressing cavity, the pressing plate 55 presses the front (left) bamboo tube in the rotating process, so a stopper 56 is arranged on the upper side of the inner wall of the side groove 52 in the pressing bin 51, the stopper 56 has a downward inclined surface, when the bamboo tube falls into the pressing bin 51, the bamboo tube is pressed by the stopper 56 to fall to the front, and then the bamboo tube is pressed by the pressing plate 55 to be flush from front to back.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
