Abstract

The invention discloses a processing method of a bamboo sheath round tea tray. First of all, choose the bamboo sheaths that fall off naturally, and after drying in the sun, boiling water to soften, flatten, and shape them, they are sent to a roller machine for rolling to remove the fine burrs growing on the surface of the bamboo sheaths. After being punched by a punching machine, the standard triangular bamboo sheath pieces are made; secondly, 8 pieces of standard triangular bamboo sheath pieces are arranged neatly, and the adjacent two pieces of standard triangular bamboo sheath pieces are placed with perforated tape paper dipped in water. The joints are glued tightly to make round bamboo sheath pieces; again, purchase transparent wear-resistant paper and formaldehyde-free bean glue, add isocyanate adhesive, mix evenly, and then paint on the round bamboo sheath as the rubber plate. The two sides of the shaped bamboo sheath pieces are assembled according to the specified requirements; finally, the release agent is applied to the tea tray mold, and the assembled round bamboo sheath pieces are put into the tea tray mold, and the machine is turned on and hot pressed to make Bamboo sheath round tea tray blank. After being rounded by a grinder, painted with clear oil and dried, it is made into a standard bamboo sheath round tea tray. The invention can greatly increase the economic value of moso bamboo.

Description

A kind of processing method of bamboo sheath round tea tray

technical field

The invention belongs to the field of decorative material processing, and in particular relates to a processing method of a bamboo sheath round tea tray.

Background technique

During the growth of bamboo shoots every year, nearly 30 sheath leaves will be shed from each bamboo shoot. For a long time, the beautiful sheath leaves have been left to fend for themselves because no one cares about them, causing unnecessary economic losses.

The present invention utilizes cheap bamboo sheath materials, and through special processing, makes a bamboo sheath round tea tray with beautiful appearance. This technology can meet the special needs of home decoration, can greatly increase the economic value of moso bamboo, and meet the growing needs of the people. The needs of material and cultural life, so it has broad market development prospects.

Contents of the invention

The object of the present invention is to provide a method for processing a bamboo sheath round tea tray. The present invention utilizes cheap bamboo sheath materials, and through special processing, makes a bamboo sheath round tea tray with beautiful appearance. This technology can meet the special needs of home decoration, can greatly increase the economic value of moso bamboo, and meet the growing needs of the people. The needs of material and cultural life, so it has broad market development prospects.

To achieve the above object, the present invention adopts the following technical solutions:

A processing method of a bamboo sheath round tea tray comprises the following steps:

Step 1: From February to April every year, collect bamboo sheaths that fall off naturally during the growth of bamboo shoots, and dry them for later use;

Step 2: Take the dried bamboo sheaths out of the warehouse, put them into a container, fill up with water, cover the lid, and start heating and cooking; keep the water boiling for 10-30 minutes, cool down to 60°C, open the lid of the container, and take out For bamboo sheaths, fully unfold the bamboo sheaths on the workbench and lay them out neatly in a stack of 20 to 30 pieces, and add weights to keep them flattened, ready for use;

Step 3: Take out the flattened bamboo sheath, send it to the felt roller machine for rolling several times, remove the fine burrs growing on the surface of the bamboo sheath, and set aside;

Step 4: Send the bamboo sheaths processed in step 3 into a punching machine, and punch them into standard triangular bamboo sheath pieces according to the pattern in Figure 1, and set them aside;

Step 5: Arrange 8 pieces of standard triangular bamboo sheaths neatly according to the pattern in Figure 2 on the workbench, and use perforated tape dipped in water to stick the joints of two adjacent pieces of standard triangular bamboo sheaths tightly , make a complete round bamboo sheath piece, set aside;

Step 6: Purchase glue-impregnated transparent wear-resistant paper, cut it according to the size of the round bamboo sheath pieces, and set aside;

Step 7: Purchase formaldehyde-free bean gum, add 4% of its mass isocyanate adhesive to the formaldehyde-free bean gum, stir evenly, and use a brush to evenly brush on both sides of the round bamboo sheath pieces used as glue boards , the amount of glue applied is controlled at 300g/m ² (both sides), and after aging for 10 minutes, the billets are formed according to the requirements stipulated in Figure 3;

Step 8: Use cotton cloth to dip the release agent and paint it on the tea tray mold installed in the hot press machine, put the assembled round bamboo sheath pieces into the tea tray mold, start the hot press, and make a bamboo sheath round tea tray Blank;

Step 9: Use a grinder to round the edges of the round bamboo sheath tea tray blank, then use a brush to dip in clear oil and evenly paint on the surface, and dry it to make a standard bamboo sheath round tea tray.

In the step 4, the flattened bamboo sheaths are sent to the punch press to make equilateral specification triangular bamboo sheath sheets at an angle of 45°.

In the step 5, when the standard triangular bamboo sheaths are stitched together on the workbench, the surface of the 8 standard triangular bamboo sheaths should face down, and the perforated tape should be adhered to the standard triangular bamboo sheaths. back.

The rubber-impregnated transparent wear-resistant paper purchased in the step 6 is produced by Minqing Shuanglong Bamboo Industry Co., Ltd., with a specification of 90g/m ² , in order to improve the surface wear resistance of the finished bamboo sheath round tea tray.

The formaldehyde-free bean gum in the step 7 is produced by Dehua Rabbit Baby Decoration New Materials Co., Ltd.

The purpose of adding its quality 4% isocyanate adhesive in the formaldehyde-free bean gum in said step 7 is to improve the bonding strength between the round bamboo sheath pieces.

The billet assembly rule in step 7 is: the bottom layer uses glue-impregnated transparent wear-resistant paper 3, the second layer uses round bamboo sheath pieces 4 (the surface faces downward), and the third layer uses glue-coated round bamboo sheath pieces 5 (surface facing down), the fourth layer uses round bamboo sheath pieces 6 (orientation is random), the fifth layer uses glue-coated round bamboo sheath pieces 7 (surface faces up), and the sixth layer uses round bamboo sheaths Assembled pieces 8 (surface facing up), the seventh layer (surface layer) is made of impregnated transparent wear-resistant paper 9, and the bamboo sheath round tea trays are arranged symmetrically one by one as far as possible, which is beneficial to eliminate the hot pressing of the bamboo sheath round tea trays The internal stress generated during the process prevents the bamboo sheath round tea tray from deforming.

During the assembling process in step 7, in order to increase the mechanical strength of the finished bamboo sheath round tea tray, the joints between the round bamboo sheath pieces of each layer should be staggered by an angle.

The mold release agent in the step 8 is 800-1200 centipoise silicone oil to prevent sticking of the bamboo sheath round tea tray during hot pressing.

In the step 9, the work of grinding the bamboo sheath round tea tray blank with a grinder must be arranged 24 to 48 hours after the round bamboo sheath pieces are hot-pressed and formed, so as to reduce the brittleness of the bamboo sheath round tea tray edge material and improve the bamboo sheath. The grinding accuracy of the edge of the round tea tray.

The beneficial effect of the present invention is to provide a processing method of the bamboo sheath round tea tray. This method utilizes cheap bamboo sheath materials, and through special processing, makes a bamboo sheath round tea tray with beautiful appearance. This technology can meet the special needs of home decoration, can greatly increase the economic value of moso bamboo, and meet the growing needs of the people. The needs of material and cultural life, so it has broad market development prospects.
