Description

Technical Field

[0001] The invention relates to the field of chopstick processing, in particular to a wood fiber chopstick forming device. Background Art

[0002] Traditional chopsticks made of raw wood need to be processed into long strips of wood with a length of several meters first, and then cut into short square strips slightly longer than the finished chopsticks, and then sharpened with an abrasive belt, usually grinding half of it into a cone, and then cutting the thin end flat and making the thick end into a four-sided pyramid head, and finally polishing the chopsticks to remove the edges and corners.

[0003] There will be a lot of scraps in the processing of raw wood chopsticks, which consumes a lot of wood and affects the ecological balance. The texture of raw wood is soft and easy to bend and deform. The raw wood needs to be steamed and dried first, and the processing steps are cumbersome. Moreover, raw wood is prone to mold in daily use.

[0004] Processing existing wood fiber boards into chopsticks not only effectively avoids the problem of mold on chopsticks, but also the wood fiber boards are harder in texture and do not need to be steamed, thus reducing the processing steps. Wood fiber boards are made by grinding wood into wood fibers, adding edible glue and mixing them fully, and finally pressing them into boards, which greatly reduces the waste of wood, consumes less wood, and saves tree resources.

[0005] Usually, the wood fiber boards on the market are processed according to traditional processing technology, and the short square strips are sharpened after processing. However, due to the high hardness of the wood fiber boards, the sanding belt used for sharpening will be greatly worn out, and the sanding belt needs to be replaced frequently, which increases the processing cost. Summary of the invention

[0006] Now, based on the existing wooden chopstick processing technology, in order to avoid the problem of large loss of abrasive belts when using abrasive belts to process materials with greater hardness, a processing technology for wood fiber chopsticks is proposed.

[0007] Step 1: The wood fiber board is cut along a set track to branch out the masterbatch of wood fiber chopsticks.

[0008] Step 2: Cut the four sides of the mother material and process the formed wooden chopstick blank. The processed wooden chopstick blank has a trapezoidal projection of the four sides, the end face of the thick end is a relatively large square, and the end face of the thin end is a relatively small square.

[0009] Step 3: Process both ends of the wooden chopstick blank and polish and remove the edges and corners.

[0010] If the four trapezoidal faces of the wooden chopstick blank are divided into four faces A, B, C, and D in clockwise order, faces B and D are the cutting faces in step 1, and the forward projections of these two faces are rectangles, and the forward projections of faces A and C are trapezoids. Then, faces A and C are cut in step 2, and the forward projections of the four faces of the processed wooden chopstick blank are all trapezoids.

[0011] The processing technology of the wood fiber chopsticks replaces the traditional sanding belt sharpening with a knife saw cutting method, which fundamentally avoids the loss of the sanding belt.

[0012] The purpose of the present invention is to construct a wood fiber chopstick forming device based on the proposed processing technology of wood fiber chopsticks and the need to cut the masterbatch of wood fiber chopsticks in step 2 and process them into formed wood chopstick blanks.
