Description

Technical Field

[0001] The invention relates to the technical field of bamboo product planing and milling processing equipment, in particular to a bamboo piece local profiling processing equipment for semi-finished mottled bamboo veneer chopsticks. Background Art

[0002] The existing production process of bamboo chopsticks is to cut the bamboo strips after removing the green color, form the shape of the bamboo chopsticks by contour milling, and then perform surface sanding, painting, etc. to make bamboo chopsticks. It can be seen that the traditional production process of bamboo chopsticks cannot retain the green color of the bamboo. The green color of mottled bamboo is very distinctive, which is manifested as purple-brown patches or spots on the surface of the bamboo. If the green color of mottled bamboo can be used as the finishing surface of bamboo chopsticks, it will make the bamboo chopsticks have a natural and beautiful visual effect. However, the shape of bamboo chopsticks is not a simple columnar shape. In order to facilitate the picking of food, the head of the bamboo chopstick needs to be designed with a narrow shape, which increases the difficulty of producing mottled bamboo veneer chopsticks.

[0003] In the production process of bamboo veneer chopsticks, one of the important steps is to remove the excess part of the bamboo green surface after sticking the yellow bamboo surface of the side of the semi-finished bamboo veneer chopsticks to the bamboo green surface. Since the semi-finished bamboo veneer chopsticks are made of two bamboo strips with bamboo green surfaces relatively fitted together, in order to make the head of the bamboo chopsticks have a narrowed structure, the bamboo green surface will bend to a certain extent when sticking to the yellow bamboo surface of the side of the semi-finished bamboo veneer chopsticks. This makes it difficult to achieve precise milling of the excess part of the bamboo green surface through the existing conventional profiling device. This step can only be done manually, which consumes a lot of labor costs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to develop a bamboo piece local profiling processing equipment specially suitable for the semi-finished products of spotted bamboo veneer chopsticks, so that it can replace manual completion of the semi-finished products of spotted bamboo veneer chopsticks after being attached to the bamboo green dough, and then realize efficient milling of the excess part of the bamboo green dough.

During the movement of the movable bracket 4 along the Y direction, the excess bamboo green dough 12 is milled and removed by the milling rotary tool 55.

[0053] In the above implementation manner, according to the unique shape of the semi-finished product 1 of the mottled bamboo veneer chopsticks, a corresponding partial profiling processing equipment for the semi-finished product 1 of the mottled bamboo veneer chopsticks is designed. By designing the side limiting mechanism 3, the movable bracket 4, the milling assembly 5, the driving member and other structures with specific structures and positional relationships, only simple manipulation is required to realize efficient and accurate processing of the excess part of the bamboo green skin 12 of the semi-finished product 1 of the mottled bamboo veneer chopsticks. In particular, the guide roller 54 is used in the milling assembly 5 to position the side of the semi-finished product 11 of the bamboo chopsticks, and the milling rotary tool 55 with a flush outer edge is used to position the structure of cutting the bamboo green skin 12. The elastic member 53 is used to realize automatic profiling cutting of the semi-finished product 1 of the mottled bamboo veneer chopsticks during its movement along the Y direction.

[0070] 4. Control the driving member to drive the movable bracket 4 to move to the second state, at which time the guide roller 54 abuts against the X-direction side of the semi-finished bamboo chopsticks 11, and the driving motor 57 drives the milling rotary tool 55 to rotate, so that the milling rotary tool 55 rotates at a high speed. When the movable bracket 4 moves along the Y direction, the excess bamboo green skin 12 is milled and removed by the milling rotary tool 55, so as to obtain the mottled bamboo veneer chopsticks product 7;
