Description

Technical Field

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

[0002] Freshly cut bamboo contains a high moisture content (usually 50% to 60%), and drying can reduce the moisture content 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 deformation and cracking caused by water evaporation during subsequent use, and avoid mold, rot, or insect attack and decay caused by high humidity, so as to ensure the quality of the final product and extend its service life.

[0003] When the moisture on the bamboo surface evaporates due to heating or directly seeps out from the inside of the bamboo, small water droplets will form on the bamboo surface. The water droplets on the bamboo surface will naturally move downward along the bamboo surface due to gravity. Since the cylindrical bamboo surface is smooth, in the absence of sufficiently large friction or other external forces, the water droplets will tend to move to the lowest point, and eventually gather at the bottom or lowest point of the bamboo. In this way, the closer the bamboo surface is to the bottom, the greater the humidity, and the closer it is to the top, the lower the humidity. The uneven humidity will affect the degree of drying. The top may be dried relatively early and the bottom may be dried relatively late, resulting in either the top being over-dried and cracked, or the bottom being under-dried and damp. Summary of the invention

[0004] In order to overcome the disadvantage that water droplets are affected by gravity, resulting in uneven moisture on the surface of bamboo and wood, thereby causing different drying degrees, the present invention provides a bamboo material drying and shaping device for bamboo processing.

[0005] A bamboo material drying and shaping device for bamboo wood processing, comprising a drying box, the drying box being fixedly connected to two placing trays, the bottom of the drying box being connected to a drain pipe, the placing trays being provided with placing holes distributed in an arc shape, a first rotating frame being rotatably connected between the two placing trays, the first rotating frame being rotatably connected to a second rotating ring symmetrically distributed along the first rotating frame, the second rotating ring being configured as an eccentric weight ring, the first rotating frame being rotatably connected to a rotating plate symmetrically distributed along the first rotating frame, the first rotating frame being fixedly connected to elastic telescopic rods symmetrically distributed along the first rotating frame, the telescopic ends of the elastic telescopic rods being fixedly connected to a pushing frame, the second rotating ring being extruded and matched with the adjacent pushing frame, the pushing frame being provided with threaded grooves symmetrically distributed along the pushing frame, the ends of the rotating plate being slidably connected to the adjacent threaded grooves, and the drying box being rotatably connected to a box door.

[0006] Furthermore, it also includes a connecting frame, which is fixed between the two placement plates, and the connecting frame is slidably connected to a supporting frame, and the supporting frame has arc-shaped circular holes, and the first rotating frame is fixed to a fixing rod, and the fixing rod rotates to contact the supporting frame.

[0007] Furthermore, a wedge-shaped surface is provided at the bottom end of the support frame, the fixing rod is rotated to contact the wedge-shaped surface, and the support frame is extruded and matched with the fixing rod through the wedge-shaped surface.

[0008] Furthermore, a motor is also included, the motor is fixedly connected to the drying box, the output shaft of the motor is fixedly connected to a first gear, the first rotating frame is fixedly connected to a second gear, and the second gear is meshed with the first gear.

[0009] Furthermore, it also includes a fixed frame, which is fixedly connected to the top of the drying box, and the fixed frame is rotatably connected to a rotating shaft, and the rotating shaft is fixedly connected to a first fan blade and a second fan blade, an exhaust channel is opened on the side of the fixed frame close to the first fan blade, and an air intake channel is opened on the side of the fixed frame close to the second fan blade, and the output shaft of the motor is splined with a connector.

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

[0011] Furthermore, a temperature control component is also included, and the temperature control component is used to automatically control the connection head and the rotating shaft to automatically contact and disengage according to the temperature conditions.

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

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

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention arranges the cylindrical bamboos in an arc shape on the placement plate, which not only avoids the bamboos being arranged in the same plane longitudinally, causing water droplets on the upper bamboos to fall down on the lower bamboos, but also avoids the bamboos being arranged in the same plane horizontally, causing the middle bamboos to be difficult to be blown by the rotating hot air, and can also increase the number of bamboos that can be placed.

[0015] 2. In the process of rotary drying, the second rotating ring of the present invention deflects itself, so that when rotating downward, the opening between the two rotating plates is gradually adjusted to be smaller, so as to achieve the effect of gradually gathering wind, thereby gradually increasing the intensity of drying, so as to dynamically adapt to the bamboo and wood whose surface humidity increases as it goes down. When rotating upward, the opening between the two rotating plates is gradually adjusted to be larger, so as to achieve the effect of gradually expanding wind, thereby gradually increasing the drying area.

[0016] 3. During the rotary drying process, the present invention utilizes the intermittent extrusion and cooperation between the fixed rod and the wedge-shaped surface at the bottom of the supporting frame, so that the supporting frame drives the bamboo to vibrate slightly up and down, thereby shaking off the water droplets gathered at the bottom of the bamboo, thereby accelerating the drying and shaping effect of the bamboo.

[0017] 4. The present invention utilizes a thermal expansion agent to control the automatic contact and disengagement between the connector and the rotating shaft, so that when the temperature rises to a certain level, the first blade and the second blade can automatically rotate, which accelerates the discharge of hot air on the one hand, and increases the introduction of cold air on the other hand, thereby avoiding excessive temperature caused by excessive hot air at the top of the drying box, thereby preventing the bamboo and wood at the top from drying out too quickly, and further preventing the bamboo and wood near the top from being over-dried and cracked.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1: A bamboo material drying and shaping device for bamboo processing, such as Figure 1-Figure 6As shown, a drying box 101 is included, and a placement plate 102 is fixedly connected to the left and right sides of the drying box 101. A drainage pipe 103 is connected to the left side of the bottom of the drying box 101. The lower half of the placement plate 102 is provided with placement holes 104 distributed in an arc shape. A first rotating frame 105 is rotatably connected between the two placement plates 102. A cavity is provided in the first rotating frame 105 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 the dryer. The first rotating frame 105 is rotatably connected to a second rotating ring 106 symmetrically distributed along the left and right sides of the first rotating frame 105. The second rotating ring 106 is set as a weight ring, and the weight end is always The first rotating frame 105 is rotatably connected to a rotating plate 107 which is symmetrically distributed along the front and back of the first rotating frame 105. The first rotating frame 105 is fixedly connected to an elastic telescopic rod 109 which is symmetrically distributed along the left and right of the first rotating frame 105. The telescopic end of the elastic telescopic rod 109 is fixedly connected to a pushing frame 108. The second rotating ring 106 is squeezed and matched with the adjacent pushing frame 108. The pushing frame 108 is provided with threaded grooves which are symmetrically distributed along the front and back of the pushing frame 108. The end of the rotating plate 107 is slidably connected to the adjacent threaded groove. The left side of the drying box 101 is rotatably connected to a box door 110.

[0033] like Fig. 9 As shown, it also includes a motor 301, which is fixedly connected to the top of the right side of the drying box 101, and the output shaft of the motor 301 is fixedly connected to the first gear 302, and the right side of the first rotating frame 105 is fixedly connected to the second gear 303, and the second gear 303 is meshed with the first gear 302.

[0034] First, open the box door 110, and then place each cylindrical bamboo horizontally between the two placement holes 104 on the same horizontal line of the placement trays 102 on the left and right sides, then 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, and the output shaft of the motor 301 drives the first gear 302 to rotate, thereby driving the second gear 303 to rotate, and then driving the first rotating frame 105 to rotate circumferentially around the placement tray 102, so as to achieve the effect of rotating and drying the bamboo. During drying, the dripping water is discharged from the drying box 101 through the drain pipe 103. When the first rotating frame 105 rotates, it drives the second rotating ring 106, the rotating plate 107, the pushing frame 108 and the elastic telescopic rod 109 to rotate circumferentially as a whole. During the rotation process, the second rotating ring 106 is also affected by its own eccentric weight, so that the second rotating ring 106 also rotates relative to the first rotating frame 105, and each time the second rotating ring 106 rotates to the highest position and the lowest position, the second rotating ring 106 will rotate 180 degrees.

[0035] During the above-mentioned rotation process, when rotating from top to bottom, the second rotating ring 106 rotates to squeeze the push frame 108 to slide toward one side of the compressed elastic telescopic rod 109, and 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 reduced. When rotating from bottom to top, the second rotating ring 106 rotates to gradually loosen the push frame 108, and the elastic telescopic rod 109 is reset to drive the push frame 108 to slide in the opposite direction and reset. The push frame 108 then drives the rotating plate 107 to reverse through the threaded groove, so that the opening between the two rotating plates 107 is increased, achieving the effect of gradually expanding the air when the rotating plate 107 rotates upward, thereby gradually increasing the drying area.

[0036] In summary, the present invention arranges the cylindrical bamboos in an arc shape on the placement plate 102, which can avoid the bamboos being arranged in the same plane longitudinally, causing water droplets from the upper bamboos to fall down on the lower bamboos, and avoid the bamboos being arranged in the same plane horizontally, causing the middle bamboos to be difficult to be blown by the rotating hot air, and can also increase the number of bamboos that can be placed.

[0037] During the rotary drying process of the present invention, the second rotating ring 106 deflects itself so that when rotating downward, the opening between the two rotating plates 107 is gradually adjusted to be smaller, achieving the effect of gradually gathering wind, thereby gradually increasing the intensity of drying to dynamically adapt to the bamboo and wood whose surface moisture increases the further down it is. When rotating upward, the opening between the two rotating plates 107 is gradually adjusted to be larger, achieving the effect of gradually expanding wind, thereby gradually increasing the drying area.

[0038] Embodiment 2: Based on embodiment 1, Figure 7 and Figure 8 As shown, it also includes a connecting frame 201, which is transversely fixed between the two placement plates 102. The connecting frame 201 is slidably connected to the supporting frame 202 in the up and down directions. The bottom side of the supporting frame 202 is provided with a wedge-shaped surface, and the supporting frame 202 has arc-shaped circular holes. The first rotating frame 105 is fixed with a fixing rod 203, and the fixing rod 203 rotates to contact with the wedge-shaped surface, and the supporting frame 202 is squeezed and matched with the fixing rod 203 through the wedge-shaped surface.

[0039] When placing 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 and the wedge-shaped surface at the bottom of the supporting frame 202 are squeezed and matched, so that the supporting frame 202 slides upward relative to the connecting frame 201. When the fixing rod 203 rotates to be separated from the wedge-shaped surface at the bottom of the supporting frame 202, the supporting frame 202 slides downward relative to the connecting frame 201 under the action of gravity. In this way, the supporting 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, thereby accelerating the drying and shaping effect of the bamboo and wood.

[0040] Embodiment 3: Based on embodiment 2, Fig.10 As shown, it also includes a fixed frame 401, which 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 fixed 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 play the role of an exhaust fan and a suction fan. An exhaust channel 405 is opened between the left side of the fixed frame 401 and the top of the drying box 101. The exhaust channel 405 is used to discharge the hot air in the drying box 101. An air intake channel 406 is opened between the right side of the fixed frame 401 and the top of the drying box 101. The air intake channel 406 is used to inhale relatively cold air from the outside. The output shaft of the motor 301 is spline-connected with a connector 407. When the connector 407 moves to the left, it contacts one end of the rotating shaft 402 close to the connector 407.

[0041] like Fig.11 and Fig.12 As shown, a storage tube 501 for storing ethyl acetate is also included. The storage tube 501 is fixedly connected to the drying box 101. A sliding frame 502 is slidably connected in the storage tube 501 along the left and right directions. The sliding frame 502 is rotatably connected to the connector 407.

[0042] In the drying room, hot air usually rises, resulting in a higher temperature at the top, which accelerates the evaporation of moisture at the top, causing the top to dry faster, which may cause the bamboo near the top to be over-dried and cracked. To avoid this, when the temperature rises to a certain level, 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: When the temperature rises and the ethyl acetate in the storage tube 501 expands, the sliding frame 502 slides to the left due to the push of the ethyl acetate, and the sliding frame 502 pushes the connecting head 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 connecting head 407, and 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 of the drying box 101 through the exhaust channel 405, and the second fan blade 404 introduces the external cold air through the air intake channel 406. When the temperature drops and the ethyl acetate in the storage tube 501 shrinks and resets, the generated pullback force causes the sliding frame 502 to slide to the right, and the sliding frame 502 pulls the connecting head 407 to move to the right until it is separated from the rotating shaft 402.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
