Description

Technical Field

[0001] The invention relates to the technical field of bamboo product planing and milling, in particular to a production process of mottled bamboo veneer chopsticks. Background Art

[0002] The existing production process of bamboo chopsticks is to cut the bamboo strips with the green color removed, 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, the bamboo chopsticks will 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 chopsticks needs to be designed with a narrowed shape, which increases the difficulty of producing mottled bamboo finishing chopsticks. Therefore, there is no related process reported in the existing literature for mottled bamboo finishing chopsticks with a narrowed head structure, and there is no mottled bamboo finishing chopstick product with such a structure on the market. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a production process of mottled bamboo veneer chopsticks, so that the surface of the prepared bamboo chopsticks presents a mottled bamboo green veneer effect and has a shape structure with a narrowed chopstick head.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] The production process of the mottled bamboo veneer chopsticks comprises the following steps:

[0006] Step 1: Break the bamboo tube into pieces through a bamboo breaking machine to form multiple equally divided bamboo pieces;

[0007] Step 2: Further cut the bamboo pieces into bamboo strips, with one side of the bamboo strips remaining green, and the width of the green side of the bamboo strips is 3-4 cm;

[0008] Step 3: Pass the bamboo strip with one side of the strip remaining green through a three-side planer, and slice the three yellow sides of the strip, so that a portion of the strip is made into strips of specific specifications, with a cross-sectional width of 3-4 cm and a thickness of 1.8-2.3 cm;

[0009] The other part supports bamboo green dough strips of specific specifications, with a cross-sectional width of 4.8-5.5cm and a thickness of 0.5-1mm;

[0010] Step 4: Cut the bamboo strips and bamboo green dough strips from step 3 into fixed lengths according to the length of the bamboo chopsticks;

[0011] Step 5: Cut the front end of the yellow bamboo surface opposite to the green bamboo surface of the bamboo strips cut to a fixed length to form a bevel;

[0012] Step 6: Apply glue to the yellow bamboo surface of the bamboo strip opposite to the green bamboo surface, and stick the yellow bamboo surfaces of the two bamboo strips with glue to form a semi-finished product, so that the front section of the green bamboo surface of the semi-finished product is tilted inwards;

[0013] Step 7: Cut the front section of the bamboo yellow side of the semi-finished product adjacent to the bamboo green side into a bevel;

[0014] Step 8: Apply glue to the bamboo yellow side of the semi-finished product adjacent to the bamboo green side, and fit it with the strip of bamboo green dough, so that the strip of bamboo green dough completely covers the glued bamboo yellow side;

[0015] Step 9: Cut and polish the bamboo strips of the green bamboo dough to make spotted bamboo veneer chopsticks.

[0016] Furthermore, in the production process of the above-mentioned bamboo veneer chopsticks, in step 6, the glue used for coating is cow bone glue or fish bladder glue.

[0017] Furthermore, in the production process of the above-mentioned bamboo veneer chopsticks, in step 8, the glue used for coating is cow bone glue or fish bladder glue.

[0018] Furthermore, in the production process of the above-mentioned bamboo veneer chopsticks, in step 5, the slope of the inclined surface is 3-6 degrees.

[0019] Furthermore, in the production process of the above-mentioned bamboo veneer chopsticks, in step 7, the slope of the inclined surface is 3-6 degrees.

[0020] Furthermore, the production process of the above-mentioned mottled bamboo veneer chopsticks also includes step 10: naturally drying the prepared mottled bamboo veneer chopsticks and then performing a carbonization treatment.

[0021] Furthermore, in the production process of the above-mentioned bamboo veneer chopsticks, the carbonization treatment is steam carbonization, the temperature is 220-260° C., and the heating time is 3-4 hours.

[0022] The present invention also protects the mottled bamboo veneer chopsticks product obtained by the production process of the mottled bamboo veneer chopsticks.

[0023] The beneficial effects of the present invention are as follows: the present invention provides a brand-new production process of mottled bamboo veneer chopsticks, which is achieved by cutting broken bamboo pieces into equal widths of specific specifications, and preparing bamboo strips and bamboo green surface skins of specific specifications through a three-sided planing process, cutting an inclined surface on the front section of the bamboo yellow part of the bamboo strip, applying glue and symmetrically pasting the strips, and utilizing the natural deformation of the bamboo strips to make the front section of the bamboo green part of the bamboo strips bend inward to form a narrowing structure, thereby forming a semi-finished bamboo chopstick. Then, the inclined surface is cut on the front section of the exposed side bamboo yellow surface, and then glue is applied and the bamboo green surface skin is pasted on the front section. When pasted, the front section of the bamboo green surface skin naturally bends inward along the inclined surface to form a narrowing structure. Finally, the excess bamboo green surface skin is cut and polished to obtain bamboo green veneer chopsticks with narrowed front ends. The process method is simple and easy to implement. The bamboo green surface skin is appropriately widened so that when it is pasted on the side of the semi-finished bamboo chopstick, the bamboo yellow surface on the side can be covered, and the fault tolerance rate is high. The above process fills the process gap in the market for mottled bamboo veneer chopsticks with narrowed head shapes. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Step 2: further cut the bamboo slices into bamboo strips 1, with one side of the bamboo strips 1 remaining green, and the width of the green side of the bamboo strips 1 being 3-4 cm;

[0036] Step 3: The bamboo strip 1 with one side remaining green is passed through a three-side planer to plane the three yellow sides of the bamboo strip 1, and a portion of the bamboo strip 1 is made into a bamboo strip 1 of a specific specification, the cross-sectional width of the bamboo strip 1 is 3-4 cm, and the thickness is 1.8-2.3 cm;

[0037] The other part supports a strip of bamboo green dough 2 of a specific specification, the cross-sectional width of the strip of bamboo green dough 2 is 4.8-5.5 cm, and the thickness is 0.5-1 mm;

[0038] Step 4: Cut the bamboo strips 1 and the strip-shaped bamboo green dough 2 in step 3 into fixed lengths according to the length of the bamboo chopsticks;

[0039] Step 5: Cut the front end of the yellow bamboo surface of the bamboo strip 1 cut to a fixed length, which is opposite to the green bamboo surface, to form a bevel 3;

[0040] Step 6: Apply glue to the yellow bamboo surface of the bamboo strip 1 opposite to the green bamboo surface, and stick the yellow bamboo surfaces of the two bamboo strips 1 coated with glue together to form a semi-finished product, with the front section of the green bamboo surface of the semi-finished product tilted inwards;

[0041] Step 7: Cut the front section of the bamboo yellow surface of the semi-finished product adjacent to the bamboo green surface into a bevel 3;

[0042] Step 8: Apply glue to the bamboo yellow side adjacent to the bamboo green side of the semi-finished product, and fit it with the strip of bamboo green dough 2, so that the strip of bamboo green dough 2 completely covers the glued bamboo yellow side;

[0043] Step 9: Cut and polish the portion of the strip-shaped green bamboo dough 2 extending out of the bamboo strip 1 to make spotted bamboo veneer chopsticks.

[0044] In the above implementation mode, the broken bamboo pieces are cut into equal widths of specific specifications, and a bamboo strip 1 and a bamboo green surface skin 2 with a bamboo green surface of specific specifications are obtained through a three-sided planing process. The front section of the bamboo yellow part of the bamboo strip 1 is cut with a bevel 3, and glue is applied to symmetrically bond them together. The natural deformation of the bamboo strip 1 is used to make the front section of the bamboo green surface of the bamboo strip 1 bend inward to form a narrowing structure, thereby forming a semi-finished bamboo chopstick. The front section of the exposed side bamboo yellow surface is then cut with a bevel 3, and then glue is applied to attach the bamboo green surface skin 2. When attached, the front section of the bamboo green surface skin 2 naturally bends inward along the bevel 3 to form a narrowing structure. Finally, the excess bamboo green surface skin 2 is cut and polished to obtain bamboo green facing chopsticks with a narrowed front end. The process method is simple and easy to implement. The bamboo green surface skin 2 is appropriately widened so that when it is attached to the side of the semi-finished bamboo chopstick, it can ensure that the bamboo yellow surface of the side is covered. The fault tolerance rate is high. The above process fills the process gap in the market for spotted bamboo facing chopsticks with a narrowed head shape.
