Description

Technical Field

[0001] The present invention relates to the technical field of bamboo drying, and particularly relates to a bamboo drying and shaping device for bamboo and wood processing. Background Art

[0002] Freshly cut bamboo contains a relatively high moisture content (usually 50% to 60%). Through drying, the moisture content can be reduced to a level suitable for processing and use (generally controlled between 8% and 12%). This is mainly to improve its physical and mechanical properties, prevent problems such as deformation and cracking caused by moisture evaporation during subsequent use, and avoid problems such as mildew, rot, or insect infestation of bamboo in a high-humidity environment, ensure the quality of the final product, and extend its service life.

[0003] When the moisture on the surface of bamboo and wood evaporates due to heating or seeps directly from the interior of the bamboo, small water droplets will form on the surface of the bamboo and wood. Affected by gravity, the water droplets on the surface of the bamboo will naturally move downward along the surface of the bamboo and wood. Since the surface of the cylindrical bamboo is smooth, without sufficient friction or other external forces to hinder, the water droplets will tend to move to the lowest point and finally converge at the bottom or the lowest point of the bamboo and wood. In this way, the humidity near the bottom of the bamboo and wood surface is higher, and the humidity near the top is lower. The uneven humidity will affect the drying degree, with the top being relatively dried prematurely and the bottom being relatively dried too late, resulting in either excessive drying and cracking at the top or insufficient drying and dampness at the bottom. Summary of the Invention

[0004] In order to overcome the drawback that the uneven humidity on the surface of bamboo and wood caused by the influence of gravity of water droplets leads to inconsistent drying degrees, the present invention provides a bamboo drying and shaping device for bamboo and wood processing.

[0005] A bamboo drying and shaping device for bamboo and wood processing includes a drying box. Two placing trays are fixedly connected to the drying box. A drain pipe is communicated with the bottom of the drying box. The placing trays are provided with placing holes distributed in an arc shape.

The first rotating frame is rotatably connected with second rotating rings symmetrically distributed along the first rotating frame. The second rotating rings are set as heavy rings. The first rotating frame is rotatably connected with rotating plates symmetrically distributed along the first rotating frame. The first rotating frame is fixedly connected with elastic telescopic rods symmetrically distributed along the first rotating frame. The telescopic ends of the elastic telescopic rods are fixedly connected with pushing frames. The second rotating rings are in extrusion fit with the adjacent pushing frames. The pushing frames are provided with threaded grooves symmetrically distributed along the pushing frames. The ends of the rotating plates are slidably connected with the adjacent threaded grooves. A box door is rotatably connected to the drying box.

[0006] Further, it further includes a connecting frame, the connecting frame is fixedly connected between the two placing disks, the connecting frame is slidably connected with a bearing frame, the bearing frame is provided with circular holes distributed in an arc shape, the first rotating frame is fixedly connected with a fixing rod, and the fixing rod rotates and contacts the bearing frame.

[0007] Further, a wedge-shaped surface is arranged at the bottom end of the bearing frame, the fixing rod rotates and contacts the wedge-shaped surface, and the bearing frame is in extrusion fit with the fixing rod through the wedge-shaped surface.

[0008] Further, it further includes a motor, the motor is fixedly connected with the drying box, a first gear is fixedly connected to the output shaft of the motor, a second gear is fixedly connected to the first rotating frame, and the second gear meshes with the first gear.

[0009] Further, it further includes a fixing frame, the fixing frame is fixedly connected to the top of the drying box, a rotating shaft is rotatably connected to the fixing frame, a first fan blade and a second fan blade are fixedly connected to the rotating shaft, an exhaust passage is opened on one side of the fixing frame close to the first fan blade, an air intake passage is opened on one side of the fixing frame close to the second fan blade, and a connecting head is in spline connection with the output shaft of the motor.

[0010] Further, when the connecting head moves towards one side, it contacts one end of the rotating shaft close to the connecting head.

[0011] Further, it further includes a temperature control component, and the temperature control component is used to automatically control the contact and separation between the connecting head and the rotating shaft according to the temperature condition.

[0012] Further, the temperature control component includes a storage tube for storing a thermal expansion agent, the storage tube is fixedly connected with the drying box, a sliding frame is slidably connected to the storage tube, and the sliding frame is rotatably connected with the connecting head.

[0013] Further, the thermal expansion agent stored in the storage tube is set as ethyl acetate.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. In the present invention, by arranging each cylindrical bamboo and wood in an arc shape and dispersing them on the placing disk, it not only avoids the situation that the bamboo and wood are longitudinally arranged on the same plane, resulting in the water droplets on the upper bamboo and wood dripping onto the lower bamboo and wood, but also avoids the situation that the bamboo and wood are horizontally arranged on the same plane, resulting in the middle bamboo and wood being difficult to be blown by the rotating hot air, and can also increase the number of bamboo and wood that can be placed.

[0016] 2. During the rotary drying process of the present invention, due to the self-deflection of the second rotary ring, when rotating downward, the opening between the two rotating plates gradually decreases, achieving the effect of gradually gathering wind, thereby gradually increasing the drying intensity to dynamically adapt to the bamboo and wood with increasing humidity towards the bottom. When rotating upward, the opening between the two rotating plates gradually increases, achieving the effect of gradually expanding the wind, thereby gradually increasing the drying area.

[0017] 3. During the rotary drying process of the present invention, the intermittent extrusion cooperation between the fixed rod and the wedge-shaped surface at the bottom of the bearing frame is utilized to cause the bearing frame to drive the bamboo and wood to vibrate slightly up and down, thereby shaking off the water droplets gathered at the bottom of the bamboo and wood and accelerating the drying and shaping effect of the bamboo and wood.

[0018] 4. The present invention uses a thermal expansion agent to control the automatic contact and separation between the connector and the rotating shaft, so that when the temperature rises to a certain degree, the rotation of the first fan blade and the second fan blade can be automatically realized. On the one hand, it accelerates the discharge of hot air, and on the other hand, it increases the introduction of cold air, avoiding excessive temperature caused by too much hot air at the top of the drying box, thereby preventing the bamboo and wood at the top from drying too quickly and further avoiding excessive drying and cracking of the bamboo and wood near the top.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1: A bamboo processing and drying and shaping device for bamboo, as Figures 1 - 6As shown in the figure, it includes a drying box 101. On both the left and right sides inside the drying box 101, there are fixedly connected placing trays 102. On the left side of the bottom of the drying box 101, there is a drain pipe 103 connected. In the lower half of the placing tray 102, there are arc-shaped distribution placing holes 104. Between the two placing trays 102, there is a first rotating frame 105 rotatably connected. Inside the first rotating frame 105, there is a cavity for outputting hot air to dry bamboo and wood. The air inlet end of the first rotating frame 105 is externally connected to the air outlet end of a dryer. The first rotating frame 105 is rotatably connected with second rotating rings 106 symmetrically distributed along the left and right of the first rotating frame 105. The second rotating rings 106 are set as heavy rings, and the heavy ends are always located on the lower side. In this way, when the second rotating rings 106 rotate, they will automatically rotate due to the influence of the weight. The first rotating frame 105 is rotatably connected with turning plates 107 symmetrically distributed along the front and back of the first rotating frame 105. The first rotating frame 105 is fixedly connected with elastic telescopic rods 109 symmetrically distributed along the left and right of the first rotating frame 105. The telescopic ends of the elastic telescopic rods 109 are fixedly connected with a pushing frame 108. The second rotating rings 106 are in extrusion fit with the adjacent pushing frames 108. The pushing frames 108 are provided with threaded grooves symmetrically distributed along the front and back of the pushing frames 108. The ends of the turning plates 107 are slidably connected with the adjacent threaded grooves. On the left side of the drying box 101, there is a box door 110 rotatably connected.

[0034] As Figure 9 shown in the figure, it further includes a motor 301. The motor 301 is fixedly connected to the top right of the drying box 101. The output shaft of the motor 301 is fixedly connected with a first gear 302. The right side of the first rotating frame 105 is fixedly connected with a second gear 303. The second gear 303 is meshed with the first gear 302.

[0035] First, open the box door 110, and then horizontally place each cylindrical bamboo and wood between two placing holes 104 on the same horizontal line of the placing trays 102 on the left and right sides respectively. Then, externally connect the air inlet end of the first rotating frame 105 to the air outlet end of the dryer, start the dryer and the motor 301. The output shaft of the motor 301 drives the first gear 302 to rotate, thereby driving the second gear 303 to rotate, and further driving the first rotating frame 105 to rotate circumferentially around the placing tray 102. In this way, the effect of rotating and drying bamboo and wood is achieved. During drying, the dripping water is discharged outside the drying box 101 through the drain pipe 103. When the first rotating frame 105 rotates, it drives the second rotating rings 106, the turning plates 107, the pushing frames 108 and the elastic telescopic rods 109 to rotate circumferentially as a whole. During the rotation of the second rotating rings 106, due to the weight of itself, the second rotating rings 106 also rotate relative to the first rotating frame 105. And every time the second rotating rings 106 rotate to the highest and lowest positions, the second rotating rings 106 will rotate 180 degrees.

[0036] During the above rotation process, when rotating from top to bottom, the second rotating ring 106 rotates itself to squeeze and push the push frame 108 to slide towards one side of the compression elastic telescopic rod 109. The push frame 108 drives the rotating plate 107 to rotate through the threaded groove, so that the opening between the two rotating plates 107 is adjusted to be smaller. When rotating from bottom to top, the second rotating ring 106 rotates itself to gradually release the push frame 108. The elastic telescopic rod 109 resets to drive the push frame 108 to slide back in the reverse direction. The push frame 108 then drives the rotating plate 107 to rotate in the reverse direction through the threaded groove, so that the opening between the two rotating plates 107 is adjusted to be larger, achieving the effect of gradually expanding the wind when the rotating plate 107 rotates upward, thereby gradually increasing the drying area.

[0037] In summary, in the present invention, by arranging each cylindrical bamboo and wood in an arc-shaped dispersion on the placement plate 102, it not only avoids the bamboo and wood being longitudinally arranged on the same plane, resulting in the water droplets on the upper bamboo and wood falling down onto the lower bamboo and wood, but also avoids the bamboo and wood being horizontally arranged on the same plane, resulting in the middle bamboo and wood being difficult to be blown by the rotating hot air, and can also increase the number of bamboo and wood that can be placed.

[0038] In the process of rotating drying of the present invention, through the action of the self-deflection of the second rotating ring 106, when rotating downward, the opening between the two rotating plates 107 is gradually adjusted to be smaller, achieving the effect of gradually gathering the wind, thereby gradually increasing the drying intensity to dynamically adapt to the bamboo and wood with greater humidity towards the bottom surface. When rotating upward, the opening between the two rotating plates 107 is gradually adjusted to be larger, achieving the effect of gradually expanding the wind, thereby gradually increasing the drying area.

[0039] Embodiment 2: On the basis of Embodiment 1, as Figure 7 and Figure 8 shown, it further includes a connecting frame 201. The connecting frame 201 is horizontally fixedly connected between the two placement plates 102. The connecting frame 201 is slidably connected with a bearing frame 202 in the up and down direction. The bottom side of the bearing frame 202 is provided with a wedge surface. The bearing frame 202 is provided with circular holes distributed in an arc shape. The first rotating frame 105 is fixedly connected with a fixing rod 203. The fixing rod 203 rotates and contacts the wedge surface, and the bearing frame 202 is in extrusion fit with the fixing rod 203 through the wedge surface.

[0040] When placing the bamboo and wood, each bamboo and wood passes through the corresponding circular hole of the receiving frame. During the rotation of the first rotating frame 105, the first rotating frame 105 drives the fixing rod 203 to rotate synchronously. When the fixing rod 203 rotates to the lowest position, the fixing rod 203 is in extrusion fit with the wedge surface at the bottom of the bearing frame 202, so that the bearing frame 202 slides upward relative to the connecting frame 201. When the fixing rod 203 rotates away from the wedge surface at the bottom of the bearing frame 202, the bearing frame 202 slides downward relative to the connecting frame 201 under the action of gravity. In this way, the bearing frame 202 drives the bamboo and wood to vibrate slightly up and down, thereby shaking off the water droplets gathered at the bottom of the bamboo and wood and accelerating the drying and shaping effect of the bamboo and wood.

[0041] Example 3: On the basis of Example 2, as Figure 10 shown, it further includes a fixing frame 401, the fixing frame 401 is fixedly connected to the top of the drying box 101, a rotating shaft 402 is rotatably connected between the left and right sides of the fixing frame 401, the left and right ends of the rotating shaft 402 are respectively fixedly connected with a first fan blade 403 and a second fan blade 404, the first fan blade 403 and the second fan blade 404 respectively function as an exhaust fan and a suction fan, an exhaust passage 405 is opened between the left side of the fixing frame 401 and the top of the drying box 101, the exhaust passage 405 is used to discharge the hot air in the drying box 101, an intake passage 406 is opened between the right side of the fixing frame 401 and the top of the drying box 101, the intake passage 406 is used to inhale the relatively cold air outside, the output shaft of the motor 301 is splined with a connector 407, and when the connector 407 moves to the left, it contacts with one end of the rotating shaft 402 close to the connector 407.

[0042] As Figure 11 and Figure 12 shown, it further includes a storage pipe 501 for storing ethyl acetate, the storage pipe 501 is fixedly connected to the drying box 101, a sliding frame 502 is slidably connected in the storage pipe 501 in the left-right direction, and the sliding frame 502 is rotatably connected to the connector 407.

[0043] In the drying chamber, hot air usually rises, resulting in a higher temperature in the upper part, thus accelerating the evaporation of moisture at the top, leading to faster drying at the top, and further possibly causing the bamboo and wood near the top to be over-dried and cracked. To avoid this situation, when the temperature rises to a certain degree, on the one hand, the discharge of hot air can be accelerated, and on the other hand, the introduction of cold air can be increased. Specifically:

[0044] When the temperature rises and causes the ethyl acetate in the storage pipe 501 to expand, the sliding frame 502 is pushed by the ethyl acetate to slide to the left, and the sliding frame 502 pushes the connector 407 to move to the left until it contacts the rotating shaft 402. In this way, the output shaft of the motor 301 drives the rotating shaft 402 to rotate through the connector 407, the rotating shaft 402 drives the first fan blade 403 and the second fan blade 404 to rotate synchronously, the first fan blade 403 discharges the hot air at the top in the drying box 101 through the exhaust passage 405, and the second fan blade 404 introduces the cold air outside through the intake passage 406. When the temperature drops and causes the ethyl acetate in the storage pipe 501 to contract and reset, the generated pulling force causes the sliding frame 502 to slide to the right, and the sliding frame 502 pulls the connector 407 to move to the right until it disengages from the rotating shaft 402.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
