Description

Cut open bamboo machine material loading structure

Technical Field

The utility model relates to a bamboo processing field specifically is for cuing open bamboo equipment, in particular to cut open bamboo machine material loading structure.

Background

When the bamboo is made into goods such as bamboo mats, bamboo curtains, bamboo chairs and the like, the harvested complete bamboo tubes are processed into slender bamboo strips. The bamboo tube is cut into bamboo strips by a bamboo cutting machine commonly used in the modern bamboo industry. The bamboo cutting machine basically adopts the working principle that a bamboo tube is horizontally placed, a certain thrust force is applied from the tail of the bamboo tube, the bamboo tube is horizontally pushed to a special cutter head which is fixedly and concentrically placed and is provided with a plurality of radial blades, and the bamboo tube completely penetrates through the cutter head and can be divided into a plurality of bamboo strips with the same size. How to convey one bamboo tube to a position concentric with the cutter head at certain time intervals for a long time is one of important factors for ensuring the normal operation and the function of the bamboo cutting machine.

The invention patent application with publication number CN 106738138A discloses a feeding assembly of bamboo cutting equipment. The bamboo tubes are collected through a cross frame in the feeding process, the bamboo tubes are loaded by a feeding support, and the bamboo tubes are loaded upwards to a station where the bamboo tubes are to be cut by the feeding support which is driven by a feeding motor and fixed on a feeding chain. However, in the actual working process, because the sizes of the bamboo tubes are changed, for example, the thicknesses and the lengths of the bamboo tubes are not consistent, and even the thicknesses of different positions of the same bamboo tube are different, the feeding support cannot be conveyed smoothly by one bamboo tube in the process of carrying the bamboo tubes, for example, two bamboo tubes are lifted simultaneously, or one bamboo tube cannot be lifted.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a cut open bamboo machine charge-in structure can overcome prior art's weak point, adopts multiple more reasonable thin and more scientific ingenious structure, guarantees that the thick bamboo tube keeps steadily transporting to blade disc place station in longer time.

The above technical purpose of the present invention can be achieved by the following technical solutions:

a feeding structure of a bamboo splitting machine comprises a material placing frame for placing a bamboo tube to be processed, and a lifting mechanism for lifting and conveying the bamboo tube placed on the material placing frame to a position for splitting the bamboo tube; the discharging frame is positioned at the side part of the bamboo splitting machine and comprises two material placing bottom frames which are arranged at intervals and are arranged along the bamboo splitting machine in a transverse front-low and back-high mode, cross rods which are arranged along the front-back direction of the bamboo splitting machine and fixedly connected to the front ends of the two material placing bottom frames, and material bearing rods of which the two ends are fixedly lapped on the material placing bottom frames and the upper parts of the cross rods along the transverse direction of the bamboo splitting machine; hoist mechanism includes along the support frame of two vertical extensions that cut open bamboo machine fore-and-aft direction and set up, locates two the mount at support frame middle part is located mount top and rotate connect in the roll axis at support frame top, two intervals are rotating the cover and are being located last mounting bracket on the roll axis is located correspondingly the lower mounting bracket of mount below, install in the roll axis with vertical chain of actuating on the lower mounting bracket, fix locating with the interval on the chain hoist frame.
