Description
Technical Field
The invention relates to the field of processing of bamboo raw materials, in particular to a processing method of a bamboo curtain.
Background
Bamboo resources in China are rich, and the bamboo has the characteristics of short growth cycle and hard material. Bamboo curtains are curtains made of bamboo and are increasingly used in the field of plywood.
The plywood is formed by gluing a plurality of layers of sheet materials up and down, and certain gluing strength is required among the layers. The inner and outer surfaces of the bamboo are respectively provided with a waxy layer (the surface of the bamboo yellow is presented with a waxy film), the existence of the waxy layer can cause the plywood not to reach the water-resistant requirement, and simultaneously, the bonding strength of the upper layer and the lower layer of the plywood can be influenced.
In order to solve the problem, when the bamboo curtain is used in a plywood, the wax layer generally needs to be removed, or the influence of the wax layer on the bonding strength of the upper layer and the lower layer is eliminated, and the specific methods mainly include three methods:
firstly, a radial bamboo curtain is adopted, as shown in fig. 1, a unit bamboo tube 100 with a fixed length is split into a plurality of arc-shaped bamboo blanks 101, then the arc-shaped bamboo blanks 101 are divided into a plurality of bamboo chips 102 with bamboo green and tabasheer with basically equal thickness (thickness is A) in a multi-stage planning manner along the thickness direction (radial direction) of the arc-shaped bamboo blanks 101, then the bamboo chips 102 with bamboo green and tabasheer are flatly arranged along the width direction (namely the radial thickness of the arc-shaped bamboo blanks 101) and then are sewn or woven into a bamboo curtain 200 in series, in the process, the wax layers on the bamboo green surface 120 and the tabasheer surface 130 are not processed, after the bamboo curtain 200 is formed, the wax layers are in a vertical position, so that the plywood pressed by taking the bamboo curtain 200 as a material lacks transverse strength, meanwhile, because the multi-stage planned bamboo chips 102 with bamboo green and tabasheer are thinner, the thickness A is generally about 1.5-2.4 mm, and the conditions such as breakage and the like are easy to occur in the feeding process of equipment, in addition, the number of the blanking points is large, so that the realization of automatic processing is very difficult, and the production efficiency is low.
And secondly, a chemical soaking mode is adopted, and a wax layer on the surfaces of the green bamboo and the yellow bamboo is removed through chemical reaction, but in the process, the chemical reaction time is at least 30 minutes, so that the production efficiency is greatly reduced, and meanwhile, the soaking waste liquid can cause environmental pollution and needs environmental protection treatment and investment increase.
Thirdly, the wax layer is removed by adopting a planing method, the method adopts a planer tool to plane the green bamboo surface and the tabasheer surface so as to achieve the aim of removing the green bamboo surface and the tabasheer surface, but the method can cause great loss of raw materials, the loss is generally about 20-30%, and the economic ratio is poor.

Detailed Description
To further illustrate the technical means adopted by the present invention and the effects thereof, the following detailed description is given with reference to the preferred embodiments of the present invention and the accompanying drawings thereof.
The invention provides a processing method of a bamboo curtain, which comprises the following steps:
step S1, providing round bamboos, and cutting the round bamboos to obtain a bamboo tube 1;
step S2, splitting the bamboo tube 1 along the length direction to obtain a raw material bamboo blank 40;
step S3, removing the wax layer, namely removing the wax layer on the green surface and the yellow surface of the raw material bamboo blank 40 to obtain the sand-surface bamboo blank 41;
step S4, making the plurality of sand-faced bamboo blanks 41 into the bamboo curtain 6.
Specifically, in step S1, the length of the bamboo tube 1 is determined by the specific size requirement of the bamboo curtain required finally.
The step S2 is to split the bamboo tube 1 along the length direction equally to obtain the raw material bamboo blank 40; the width of the raw material bamboo blank 40 is 1 mm-150 mm.
And step S3, removing the wax layers on the green surface and the yellow surface of the raw material bamboo blank 40 by a grinding method.
The step S4 specifically includes weaving or sewing a plurality of sand-faced bamboo blanks 41 in series into the bamboo curtain 6 in a manner that the green faces or yellow faces of the bamboo are laid flat.
First embodiment (shown in fig. 2):
in the step S2, the width B1 of the raw bamboo blank 40 is 5mm to 20 mm. Here, the width B1 of the raw bamboo blank 40 is selected depending on the diameter of the round bamboo, in addition to the consideration of the processing equipment, and the larger the diameter is, the larger the width B1 may be selected accordingly.
In step S3, a pair of rotating roller-type wire brushes 51 (the rotation direction is M direction in fig. 2 or the opposite direction) are used to brush and cut the green surface and the yellow surface of the raw bamboo blank 40, respectively, to remove the wax layer on the green surface and the yellow surface, and the cross-sectional shape of the obtained sand-surface bamboo blank 41 is arc-shaped.
The position of the roller type wire brush 51 can be adjusted up and down along the V direction so as to control the brushing thickness, and the brushing thickness of the arc-shaped surface can be controlled within 0.05 mm-0.5 mm because the steel wires forming the roller type wire brush 51 have certain elasticity, thereby greatly reducing the material loss. Experiments prove that the material loss can be controlled within 5 percent. The roller-type wire brushes 51 used in the present embodiment may be a plurality of pairs, or may be replaced by planar wire brushes, or of course, grinding methods such as a grinding wheel, an abrasive cloth wheel, or shot blasting may be used to achieve the same technical effects.
Second embodiment (shown in fig. 3):
in the step S2, the bamboo tube 1 is split into two, four or six halves along the length direction (of course, other parts of the bamboo tube 1 may be split into equal halves according to actual needs, but the invention is not limited thereto), so as to obtain the raw bamboo blank 40. The width B2 of the raw material bamboo blank 40 is 7 mm-150 mm, preferably 30 mm-80 mm.
The step S23 is further included between the step S2 and the step S3: the raw bamboo blank 40 is rolled to make its surface substantially flat.
Specifically, in step S23, the raw bamboo blank 40 is rolled by a pair of rolling rollers 50, and the rolling strength applied by the rolling rollers 50 is 3 to 10N/mm2。
The flattening rollers 50 can be adjusted up and down in the V direction to obtain a suitable flattening force.
In the step S3, a pair of flat wire brushes 52 is used to brush and cut the green surface and the yellow surface of the raw material bamboo billet 40 respectively to remove the wax layer on the green surface and the yellow surface, and the cross section of the obtained sand-surface bamboo billet 41 is rectangular.
The planar wire brush 52 is provided with a working surface 520, the working surface 520 can also be adjusted up and down along the V direction, so as to control the thickness of brushing the surf green surface and the surf green surface, and the thickness of brushing is generally controlled to be 0.05 mm-0.5 mm, thereby achieving the minimum material loss. The loss of the material is below 5% through test verification.
In operation, the planar wire brush 52 rotates (in the direction of M' in fig. 3) on a plane parallel to the raw bamboo cane 40, and the rotation speed thereof is adjustable according to the operation speed, so that the wax layer is repeatedly scraped and removed by the wires of the planar wire brush 52.
In this embodiment, the flat wire brush 52 can be replaced by a roller wire brush, and other similar technical means such as a flat grinding wheel, a roller grinding wheel, a polishing tile and other grinding methods can achieve the same technical effect. In this embodiment, the flat wire brush 52 and the flattening roller 50 may be provided in plural pairs. In this embodiment, the surficial roughness of the surficial green surface and the surficial yellow surface after being brushed by the planar wire brush 52 in a rotating manner is relatively high while the wax layer is removed, which is beneficial to subsequent gluing and further beneficial to improving the comprehensive strength (radial and transverse) of the finished plywood.
In this embodiment, the step S23 and the step S3 may be performed simultaneously, that is, the raw bamboo cane 40 is fed in the direction of arrow N, and two pairs of flattening rollers 50, 50 'and two pairs of flat wire brushes 52, 52' are alternately arranged, as shown in fig. 4 and 5, so that the rolling process can be performed while removing the wax layer.
In this embodiment, a bamboo joint removing process may be added, that is, the bamboo curtain processing method further includes step S23': the knot removing, i.e. removing the bamboo joints of the raw bamboo adobe 40, mainly considers the bamboo yellow surface joints which have a large influence on the formation of the plywood, and the best time for removing the bamboo joints is to roll the bamboo joints (i.e. step S23) at the same time, i.e. to roll the bamboo joints in the same processing procedure. As shown in fig. 6 and 7, the raw bamboo cane 40 is fed at a constant speed in the direction of arrow N, and at the same time, a plurality of pairs of flattening rollers 50 may be provided,the rolling roller 50 can apply 3-10N/mm to the surface of the raw bamboo blank 40 according to the specific year and hardness of the raw bamboo blank 40 during rolling2The pressure of the bamboo joint is ensured to be automatically separated after the partially brittle bamboo joint is damaged by the grinding force, meanwhile, the node removing roller 54 is arranged, the node removing roller 54 can be used for planing the bamboo joint, in the process, the tabasheer surface faces downwards, so that the separated bamboo joint scraps can leave the raw bamboo blank 40 under the action of self weight. In the present embodiment, it is necessary to control the rolling force of the rolling roller 50, which is set at a certain value such that the rolling roller 50 can float in the V direction when the rolling resistance is greater than the certain value, in consideration of the hardness of the outer bamboo joint.
Considering the elasticity of bamboo, in order to prevent the cross-sectional shape of the rolled raw bamboo blank 40 from rebounding and causing inconvenience to the subsequent weaving process (step S4), a reverse bending process may be added in this embodiment, that is, the processing method of the bamboo curtain further includes step S34: and (3) reverse bending, namely, reverse bending rolling is carried out on the sand-surface bamboo blank 41, as shown in fig. 8, the cross section of the sand-surface bamboo blank 41 obtained after the raw material bamboo blank 40 is rolled by a plurality of pairs of flattening rollers 50 is changed into a rectangular shape, and in the process, the joint removing and brushing processes can be simultaneously carried out. And then, reversely bending and rolling the sand-surface bamboo blank 41 by at least one pair of reverse bending rollers 53, wherein the reversely bent sand-surface bamboo blank 41 is used for weaving or sewing the bamboo curtain 6, and the reverse bending angle is between 5 and 15 degrees.
In the above embodiment, the wax layer is removed by using the rotating wire brush (the roller wire brush 51 or the plane wire brush 52), so that the processing speed can be effectively increased, and the production efficiency can be further improved. Meanwhile, the whole process of the bamboo curtain processing method can be completed on one production line, and automation of processing equipment is facilitated. Although the same technical effects can be achieved by adopting grinding methods such as a grinding wheel, an abrasive cloth wheel or shot blasting, the methods have some defects in the aspects of economy and production efficiency in specific use, for example, the grinding material replacement problem exists in the shot blasting method, and a special closed shot blasting chamber is needed, so that an intermittent operation mode is performed, namely a certain number of bamboo blanks are placed into the shot blasting chamber and are taken out after being ground for subsequent process processing, and the production efficiency is low; or continuous flow production is carried out, so that a special polishing-resistant flow line is required, and the manufacturing cost and the maintenance cost of the production line are high and poor in economical efficiency. For another example, the grinding of the grinding wheel is mainly realized by the roughness of sand grains by using a grinding wheel method, when the wax layer is ground, the wax layer is easily adhered to the surface of the grinding wheel, so that the surface of the grinding wheel is smooth, the grinding function is lost, the grinding wheel needs to be continuously replaced to maintain the grinding function, and thus, the maintenance cost and the production efficiency are not ideal.
In summary, the invention provides a bamboo curtain processing method, which comprises the following steps: step S1, providing round bamboos, and cutting the round bamboos to obtain bamboo tubes; step S2, splitting the bamboo tube along the length direction to obtain a raw material bamboo blank; step S3, removing the wax layer, namely removing the wax layer on the green surface and the yellow surface of the raw bamboo blank to obtain the sand-surface bamboo blank; step S4, manufacturing a plurality of sand-surface bamboo blanks into a bamboo curtain; and step S3, removing the wax layer on the green surface and the yellow surface of the raw bamboo blank by a grinding method. The invention adopts a grinding method (such as brushing) to remove the wax layers on the surfaces of the bamboo green and the bamboo yellow, can effectively control the removed thickness and furthest ensure the minimization of material loss; meanwhile, the processing speed can be effectively improved, and the production efficiency is further improved; each surface of the sanded bamboo blank after brushing has a relatively large roughness, which is beneficial to subsequent gluing and further beneficial to improving the comprehensive strength (radial and transverse) of the finished plywood. After the brushing method is adopted, the whole process from the processing of the bamboo tube to the bamboo curtain can be finished on one production line, which is beneficial to the automation of processing equipment.
As described above, it will be apparent to those skilled in the art that various other changes and modifications can be made based on the technical solution and the technical idea of the present invention, and all such changes and modifications should fall within the protective scope of the appended claims.
