Description
Technical Field
The invention belongs to the field of bamboo processing machinery, and relates to a whole bamboo tube continuous green removing device, in particular to a whole bamboo tube continuous green removing device which is used for conveying a whole bamboo tube into a channel formed by an abrasive belt driven wheel, a bamboo tube driving wheel I and a bamboo tube driving wheel II, driving the bamboo tube to rotate by the bamboo tube driving wheel I and the bamboo tube driving wheel II, feeding the bamboo tube axially, and grinding the whole bamboo tube by an abrasive belt.
Background
Moso bamboo is an important forest resource which is fast-growing, high-yield, high-quality and easy to update and recover. It has short growth period and excellent physical and mechanical performance. However, compared with wood, the bamboo wood has the geometrical characteristics of small diameter, thin and hollow wall, large sharpness, elliptical cross section, different degrees of bending along the length direction and the like, and brings a plurality of problems and difficulties for the processing and the utilization of the bamboo wood. Therefore, the processing difficulty of the bamboo is much higher than that of wood, the realization of industrial utilization is not as common as that of wood, and the processing difficulty is mainly represented in the following aspects:
(1) The utilization rate of bamboo wood is low. The adhesive can not wet the outer surface of the bamboo and the inner surface of the bamboo, and the adhesive has very different properties from the middle layer of the bamboo. The material which can be really utilized in the bamboo processing is mainly bamboo in the middle part, and products which are called as deep finishing at present, such as bamboo floors and rotary-cut micro-thin bamboo which are spliced by bamboo chips after the bamboo chips are processed, the utilization rate of the bamboo is below 30%, so that the great waste of bamboo resources is caused, and meanwhile, the production cost of the products is increased.
(2) The processing technology and method of bamboo wood are unreasonable. At present, bamboo is sawn, sectioned or shaved, and can only be processed into bamboo chips with the width of 15-20 mm and the thickness of 5-7 mm, so that the bamboo chips are difficult to directly use. To obtain the plates and square timber, the bamboo chips must be glued together, so the glue consumption of the product is great.
(3) The equipment precision and automation level are not high. Because of the special structure of bamboo, most products processed by bamboo can only realize mechanized production, and part of working procedures or products are difficult to get rid of manual labor. Many existing bamboo processing equipment cannot meet production requirements, and processing precision is low. Because the existing equipment is basically imitated or improved by woodworking machinery, the equipment cannot be well suitable for processing bamboo wood, and has influence on product quality, efficiency, cost, equipment reliability, durability, automation degree and the like, and has lower safety in the production process and even endangers personal safety. Therefore, the labor production efficiency of the bamboo processing industry is low, and the production requirement of modern high-quality bamboo products cannot be met.
(4) The bamboo material has obvious difference in structure and chemical composition from wood, and contains more nutrients such as hemicellulose, starch, protein, sugar, etc. than wood, so that the bamboo product has less insect resistance, corrosion resistance and mildew resistance than wood product.
In order to obtain products with good quality and high added value, expand the application field of bamboo processing products, improve the utilization rate of bamboo, and the insect resistance, corrosion resistance and mildew resistance, the moso bamboo must be further processed by adopting a unique processing technology and a processing method. If the moso bamboo can be unfolded into a crack-free bamboo flat plate, the crack-free bamboo flat plate with the width of 250-400mm, the length of 1300-2500mm and the thickness of 7-10mm can be obtained. The bamboo plate can be directly used as a decorative material, can also be used as a bamboo floor, and can be used for manufacturing various decorative materials such as composite floors, furniture panels, artificial boards and the like by slicing the bamboo plate into micro-thin bamboo with different thicknesses and pasting the micro-thin bamboo on various plate bases. To realize crack-free expansion of the whole bamboo tube, the bamboo tube is expanded into a bamboo flat plate, the bamboo green on the outer surface of the bamboo tube, bamboo joints and tabasheer in the inner hole of the bamboo tube are removed, and the bamboo flat plate is longitudinally slotted and softened after being subjected to equal-thickness processing and then expanded. At present, a green removing cutter or an abrasive belt is adopted for removing green of the bamboo tube, and the combined cutter is driven by a green removing machine transmission mechanism to perform reciprocating scraping motion (CN 200920009188.0, circumferential autorotation intensive combined cutter), so that the whole bamboo surface can be completely scraped by two reciprocations, and the green removing of the whole moso bamboo is completed; the patent (CN 200910133439.0, a reciprocating method for removing green skin on the surface of the moso bamboo) simulates manual green removing action, and scrapes the green skin on the surface of the whole bamboo along the direction of the moso bamboo fiber; in the patent (CN 201220274167.3, a moso bamboo green removing machine) is provided with a portal frame and a moso bamboo fixing device on a frame, and a cutter assembly on the portal frame is driven by a traction chain to move relative to a bamboo tube to remove the green; the three green removing methods are all to scrape off the green of the surface of the bamboo tube by adopting the reciprocating motion of a cutter along the bamboo tube, the outer circle surface of the green removed bamboo tube is not smooth, certain edges and corners exist, and cracks can be generated when the bamboo tube is unfolded into a bamboo flat plate. The patent (CN 201710140194.9, a bamboo tube green removing machine) uses an abrasive belt to grind off the green of the bamboo, and can be suitable for curved bamboo tubes, wherein one end of the bamboo tube is bigger than the other end of the bamboo tube, and the section of the bamboo tube is elliptical, but the processed bamboo tube needs to be taken down after one bamboo tube is processed, the next bamboo tube is clamped, a certain clamping time is needed, and the productivity is affected.

The structure of other parts in the shaft system is identical except that the connection form of the bearing seat and the vertical mounting plate is different; the bamboo tube driving wheel I and the bamboo tube driving wheel II are all cantilever-arranged on a rotating shaft in a bearing seat, the circumferential fixation with the rotating shaft is realized by using flat keys, two ends of a connecting piece are respectively connected with the bearing seat and a flange of a motor and a stepless speed changer by using bolts, the motor and the stepless speed changer are connected with the rotating shaft by using sleeve couplings, the circumferential fixation of the motor and the stepless speed changer with the sleeve couplings, the sleeve couplings with the rotating shaft is realized by using two flat keys, and the torque is transmitted to the bamboo tube driving wheel II and the bamboo tube driving wheel I.
The upper end of a bearing seat in the bamboo tube driving wheel II and a shaft system thereof is welded with a connecting plate, a wedge-shaped base plate is arranged between the connecting plate and the vertical mounting plate, the wedge angle of the wedge-shaped base plate is alpha, and after the connecting plate on the bearing seat is fixed on the vertical mounting plate by a bolt, the bamboo tube driving wheel II and the shaft system thereof can be ensured to deviate by an angle alpha relative to the axis of the abrasive belt driven wheel in a vertical plane; the wedge-shaped backing plates with different wedge angles are replaced, so that the size of the deflection angle alpha between the generatrix of the driving wheel II of the bamboo tube and the generatrix of the bamboo tube in a vertical plane can be changed, and the feeding speed of the bamboo tube during grinding is changed; the greater the deflection angle alpha, the faster the feed speed of the bamboo tube along the belt under the same rotation speed condition of the bamboo tube, and the slower the feed speed of the bamboo tube along the belt.
The upper end of a bearing seat in the bamboo tube driving wheel I and a shaft system thereof is welded with a guide shaft, the guide shaft passes through a guide sleeve fixed on a vertical mounting plate, and a guide key, a hanging shaft, a pin shaft I and a lever are sequentially arranged on a guide shaft section penetrating out of the guide sleeve; fixing a guide key on a guide shaft by using a screw, wherein the guide key is embedded and fixed in a groove of a guide seat at the top end of the vertical mounting plate; one end of each tension spring is respectively hung on two sides of the hanging shaft, and the other end of each tension spring is respectively hung on the two tension spring hanging seats; the lever is arranged in a groove at the top end of the guide shaft, and the pin shaft I penetrates through the U-shaped hole at the head of the lever and the hole of the guide shaft to hinge the lever with the guide shaft.

The abrasive belt driven wheel and the bamboo tube driving wheel II rotate in a fixed shaft manner, and the bamboo tube driving wheel I rotates along with the change of the sharpening degree of each bamboo tube, the change of the ovality of the cross section of the bamboo tube and the different diameter of each bamboo tube, and slides up and down along the guide sleeve along with the whole shaft system; the guide shaft installed in the guide sleeve slides downwards along the guide sleeve under the action of the dead weight of the bamboo tube driving wheel I and the shaft system thereof and the two tension springs, when the lower end of the guide key fixed in the guide shaft slides to the upper end of the guide sleeve, the guide shaft is limited, the bamboo tube driving wheel I and the shaft system thereof are at the lowest position, and at the moment, the channel formed by the abrasive belt driven wheel, the bamboo tube driving wheel II and the bamboo tube driving wheel I is the smallest.

The deflection angles alpha of the generatrix of the bamboo tube driving wheel II and the bamboo tube generatrix in the vertical plane are equal to the deflection angles alpha of the generatrix of the bamboo tube driving wheel I and the bamboo tube generatrix in the horizontal plane, and the size of alpha can be determined according to the green removing thickness requirement of the bamboo tube; when the rotational speeds of the bamboo tube driving wheel I and the bamboo tube driving wheel II are fixed, the feeding speed of the bamboo tube relative to the abrasive belt is higher, so that when the linear speed of the abrasive belt relative to the bamboo tube is fixed, the required green removing thickness is higher, the value of alpha is smaller, and the proper alpha value of the device is between 3 degrees and 8 degrees.
A layer of rubber piece is adhered to the outer circles of the bamboo tube driving wheel I and the bamboo tube driving wheel II, so that the friction coefficient between the bamboo tube driving wheel I and the surface of the bamboo tube is improved, and the friction force between the bamboo tube driving wheel I and the surface of the bamboo tube is increased.
The left and right ends of the abrasive belt driven wheel are provided with a left depth limiting piece and a right depth limiting piece, the diameter of the left depth limiting piece is smaller than that of the right depth limiting piece, the difference between the radiuses of the right depth limiting piece and the left depth limiting piece and the height difference between the abrasive belt and the left depth limiting piece are green removing depths, the left depth limiting piece is clung to the surface of a bamboo tube which is not subjected to green removing, and the right depth limiting piece is clung to the surface of the bamboo tube which is subjected to green removing, so that the green removing depths of the whole bamboo tube are equal; if the green removing depth is changed, the diameters of the left depth limiting piece and the right depth limiting piece are adjusted, and the left depth limiting piece and the right depth limiting piece are replaced.
