Description

A bamboo tube bamboo green dust-free cleaning machine

technical field

The utility model belongs to the technical field of bamboo tube processing equipment, in particular to a bamboo tube and bamboo green dust-free cleaning machine.

Background technique

Bamboo green is mainly a layer of cells outside the bamboo stalk wall, about 0.3mm thick. For bamboo processing, since it cannot be glued, it must be removed. However, it is difficult to remove bamboo green. The reason is that the outer diameter of the bamboo tube is not a conventional circle, but is close to an ellipse, and the upper and lower parts of the bamboo tube are tapered. Regular cylindrical shape.

The traditional removal of bamboo greens is artificially polished with sandpaper. Affected by the skills of workers, the quality of the bamboo greens is also mixed. In order to improve the efficiency and removal quality, most of the methods of mechanical automatic removal of bamboo greens have been adopted.

In the prior art, patent 201610804312.7 provides a processing method for removing bamboo green and bamboo yellow from a bamboo tube. The inner and outer rollers are respectively arranged inside and outside the bamboo tube to clamp the bamboo tube, and the rotation of the inner roller and the outer roller drives the rotation of the bamboo tube. The cutter and the outer cutter, respectively, scrape off the bamboo green and bamboo yellow. Another example is the rotary bamboo green removal device provided by the patent 201410685425.0. By arranging a blade in a circular bracket, the blade is connected with a spring for clamping the bamboo, the bamboo passes through the circular bracket, the blade is pressed on the bamboo and rotates relatively, scraping the bamboo. In addition to bamboo green.

The inner wall of the telescopic rod is connected to the end of the telescopic rod, and the polishing sheet is connected to the end of the telescopic rod. This preferred solution provides a specific structure of a grinding mechanism, which utilizes a telescopic rod and a spring to realize the effective adaptation of the grinding sheet to bamboo tubes of different diameters or shapes of different parts of the same bamboo tube.

More preferably, the sanding sheet is connected to the end of the telescopic rod in a hinged manner. Because the bamboo tube is not always of constant thickness, but has a tapered structure with thin bamboo tips and thick bamboo roots, the polishing sheet is hinged with the telescopic rod, so that the polishing sheet can rotate relative to the telescopic rod, so as to be in closer contact with the outer surface of the bamboo cylinder.

More preferably, the polishing sheet includes a bottom sheet and a polishing sheet, the bottom sheet is connected with the end of the telescopic rod, and a sponge is provided between the bottom sheet and the polishing sheet. The function of the sponge is similar to that of the hinged telescopic rod of the polishing pad, both of which are to make the polishing pad more closely contact the outer surface of the bamboo tube.

Preferably, the sanding sheet is tile-shaped.

Preferably, the first limiting step is detachably connected to the stator through a screw, and the second limiting step is detachably connected to the rotor through a screw. The first limit step and the second limit step are detachable, so that the stator and rotor of the direct drive motor can be replaced, which is convenient for later maintenance.

Compared with the prior art, the beneficial effects of the present utility model are:

1. The grinding mechanism is driven by a direct drive motor. Compared with the existing conveyor belt and gear transmission, it has less power loss, takes up less space, uses fewer parts, and is convenient for later maintenance.
