Description

Technical Field

[0001] The invention belongs to the technical field of manufacturing recombined bamboo hollow columns, and in particular relates to a pressing and fixing device and a process thereof for processing glued recombined bamboo hollow columns. Background Art

[0002] Reconstructed bamboo is a new type of bamboo material that is reorganized and strengthened. It is made by crushing bamboo into bamboo fiber bundles and then drying, dipping in glue, re-drying, assembling and hot pressing. The reconstructed bamboo hollow column is formed on this basis through a specific structural design to reduce weight and improve material utilization efficiency. As people pay more and more attention to sustainable development, the reconstructed bamboo hollow column is widely used in decoration, furniture and other industries as a new type of environmentally friendly material.

[0003] The reconstituted bamboo hollow column is made of a top plate, a bottom plate and two side plates glued together, where the two side plates are located between the top plate and the bottom plate. During production, glue is applied to both sides of the side plates and then glued to the top plate and the bottom plate respectively. Finally, the top plate is squeezed from above by a clamping device so that the top plate, side plates and bottom plate fit tightly together. After the glue solidifies, a complete hollow column is obtained.

[0004] The existing device also has the following deficiencies:

[0005] 1. The two side plates of the hollow column are located between the top plate and the bottom plate and have a certain degree of freedom. When the clamping device squeezes them, the side plates are easy to slide, resulting in deviation in the position of the side plates, making the shape of the finished hollow column not meet the standards and become defective, resulting in a waste of resources.

[0006] 2. The existing device extrude from a single direction during compression, and the forces at the connection between the side plate and the top plate and the bottom plate are different. In addition, the extrusion position of the existing device is fixed, and the forces at the extrusion position are relatively large, while the forces at other positions are relatively small. These problems will cause the connection of the hollow column to have inconsistent fit, resulting in the hollow column being not firmly glued, resulting in poor stability.

[0007] 3. After the existing device compresses the hollow column, it needs to wait for the glue to dry and condense naturally. In this way, the condensation speed of the glue is relatively slow, resulting in low production efficiency of the hollow column. Summary of the invention

[0046] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0047] like Figure 1-Figure 10 As shown, a pressing and fixing device for processing glued reconstructed bamboo hollow columns includes a guide rail 1 and a clamping assembly. Two movable seats 11 are slidably connected to the guide rail 1. The movable seats 11 are provided with locking devices that can fix the movable seats 11 on the guide rail 1. The locking device is realized by the existing technology and will not be described here. The movable seat 11 is provided with a fixing assembly, which includes a support column 2 fixed on the movable seat 11. The support column 2 is hollow inside, and a through groove 21 is opened in the middle of the support column 2. The through groove 21 is square. The fixing assembly also includes a clamping component and a driving component.

[0048] The clamping component includes a first sleeve 22 and a second sleeve 23 rotatably connected to the support column 2. The number of the first sleeve 22 and the second sleeve 23 is two. Two first nuts 220 with opposite spiral directions are fixed at both ends of the first sleeve 22. The first nut 220 is threadedly connected with a first screw rod 221 and a second screw rod 222. A limiting plate 2211 is fixed on the first screw 221. A limiting groove 2221 adapted to the limiting plate 2211 is provided on the second screw 222. The limiting plate 2211 is slidably connected in the limiting groove 2221 to limit the rotation of the first screw rod 221. A supporting plate 2222 is fixed on the second screw 222. The supporting plate 2222 is slidably connected to the side wall of the support column 2. A sliding groove is provided on the supporting plate 2222. A limiting block is fixed on the side wall of the column, and the limiting block is slidably connected in the slide groove to limit the rotation of the second screw 222. An adjusting element is provided on the support plate 2222. A second nut 230 is fixed at one end of the second sleeve 23. A third screw 231 is threadedly connected to the second nut 230. A sliding rod 2311 is fixed on the third screw 231. A fixed plate is fixed on the support column 2, and a slide groove is provided on the fixed plate. A limiting block is fixed on the slide rod 2311, and the limiting block is slidably connected in the slide groove to limit the rotation of the third screw 231. The slide rod 2311 is slidably connected to the fixed plate, and a slide groove is provided on the fixed plate. A limiting block is fixed on the slide rod 2311, and the limiting block is slidably connected in the slide groove. A clamping plate 24 is fixed on both the first screw 221 and the third screw 231.

[0049] When fixing, the two ends of the preliminarily glued hollow column are placed on the two through grooves 21, and the first screw rod 221 and the second screw rod 231 are moved synchronously through threaded cooperation, so that the four clamping plates 24 simultaneously approach the hollow column to clamp the hollow column.

[0050] The adjusting element includes two guide rods 25 slidably connected to the support plate 2222 , an inner support plate 251 is fixed to the guide rods 25 , a screw 252 is rotatably connected to the inner support plate 251 , and the screw 252 penetrates the support plate 2222 and is threadedly connected to the support plate 2222 .

[0051] When fixing, the third screw 222 moves synchronously with the first screw 221 in the opposite direction, driving the inner support plate 251 to approach the inner wall of the hollow column. The clamping plate 24 and the inner support plate 251 are in contact with the hollow column at the same time. When placed and fixed, the side plate of the hollow column is offset. The position of the inner support plate 251 can be adjusted by rotating the screw 252, so that the device can be suitable for clamping and fixing hollow columns of different specifications.

[0052] The driving component includes a crown gear 26 rotatably connected to the support column 2, a first column gear 27 meshing with the crown gear 26 is fixed on the first sleeve 22 and the second sleeve 23, a first motor 28 is fixed on the support column 2, and a second column gear 29 meshing with the crown gear 26 is fixed at the output end of the first motor 28.

[0053] When fixed, the first motor 28 is turned on, the first motor 28 drives the second column gear 29 to rotate, thereby driving the crown gear 26 to rotate, and the rotation of the crown gear 26 drives the first column gear 27 to rotate, thereby driving the first sleeve 22 and the second sleeve 23 to rotate, thereby driving the first screw 221, the second screw 222 and the third screw 231 to move synchronously under the action of threaded cooperation.

[0054] The clamping assembly includes a support frame 3 fixed on the guide rail 1, with hydraulic telescopic rods 31 fixed at the upper and lower ends of the support frame 3, a mounting plate 32 fixed at the output end of the hydraulic telescopic rod 31, a rotating seat fixed on the mounting plate 32, a rotating shaft 33 rotatably connected to the rotating seat, a rolling roller 34 fixed on the rotating shaft 33, and the clamping assembly also includes a moving part and an accelerating coagulation part.

[0055] During operation, the hydraulic telescopic rod 31 is controlled to extend to drive the mounting plate 32 and the rolling roller 34 to approach the hollow column until the pressure of the rolling roller 34 on the hollow column reaches a preset value, and pressure is applied to the upper and lower sides of the hollow column at the same time, so that the force on the upper and lower sides of the hollow column is more even.

[0056] The moving component includes a second motor 41 fixed on one of the movable seats 11, a third column gear 42 is fixed to the output end of the first motor 41, two symmetrical fourth column gears 43 are rotatably connected to the movable seat 11, the third column gear 42 is respectively meshed with the two fourth column gears 43, and a rack 44 meshed with the fourth column gear 43 is fixed to the inner side of the guide rail 1.

[0057] During operation, the second motor 41 is turned on to drive the third column gear 42 to rotate, and the rotation of the second column gear 42 drives the two fourth column gears 43 to rotate synchronously in the opposite direction. With the cooperation of the rack 44, the movable seat 11 moves along the guide rail 1. The second motor 41 is rotated forward and reversely to make the fixed component carry the hollow column to reciprocate along the guide rail 1, so that the rolling roller 34 applies pressure to different positions of the hollow column.

[0058] The accelerating coagulation component includes a cam 51 fixed to the two ends of the rotating shaft 33, two symmetrical piston cylinders 52 are fixed on the mounting plate 32, a piston plate 53 is sealingly and slidingly connected inside the piston cylinder 52, a piston rod 54 is fixed on the piston plate 53, a spring 55 is sleeved on the piston rod 54, two ends of the spring 55 are respectively fixed on the piston plate 53 and the piston cylinder 52, the piston rod 54 is in contact with the cam 51, and an air guide pipe 56 is fixed on the air outlet of the piston cylinder 52.

[0059] During operation, the rolling roller 34 drives the rotating shaft 33 to rotate, thereby driving the cam 51 to rotate. The rotation of the cam 51 drives the piston rod 54 and the piston plate 53 to move back and forth up and down in the piston cylinder 52. The air flow blown out of the piston cylinder 52 blows to the connection of the hollow column through the air guide pipe 56, accelerating the condensation of the glue at the connection.

[0060] like Fig.11 As shown, the present invention also provides a pressing and fixing process for a pressing and fixing device used for processing a glued reconstructed bamboo hollow column, comprising the following steps:

[0061] S1. Apply glue to the side panels and combine them with the top and bottom panels to form a hollow column, and complete preliminary gluing;

[0062] S2, placing the two ends of the assembled hollow column in the two through slots 21 respectively, and turning on the first motor 28 to fix the hollow column;

[0063] S3, after the hollow column is fixed, the first motor 28 is turned off, and then the hydraulic telescopic rod 31 is controlled to extend so that the rolling roller 34 squeezes the hollow column;

[0064] S4, turning on the second motor 41, driving the hollow column to move back and forth by the second motor 41 in forward and reverse rotation, so that the rolling roller 34 acts on different positions of the hollow column;

[0065] S5. After the hollow column is completely glued, remove it, and then drive nails into the joints of the hollow column to further fix it.

[0066] The working principle of the present invention is as follows:

[0067] During operation, the two ends of the preliminarily glued hollow column are placed in the two through grooves 21 respectively, and then the first motor 28 is turned on. The first motor 28 drives the second column gear 29 to rotate, thereby driving the crown gear 26 to rotate. The rotation of the crown gear 26 drives the first column gear 27 to rotate, thereby driving the first sleeve 22 and the second sleeve 23 to rotate. Two first nuts 220 with opposite spiral directions are fixed at both ends of the first sleeve 22, and the second nut 230 is fixed on the second sleeve 23, thereby driving the first screw rod 221, the second screw rod 222 and the third screw rod 231 to move synchronously under the action of thread cooperation. The movement of the first screw 221 and the third screw 231 drives the four clamping plates 24 to approach the hollow column at the same time and clamp the hollow column, and the centering of the hollow column is achieved synchronously during fixing. The center line of the hollow column naturally coincides with the center line of the support frame 3, ensuring that the upper and lower sides of the hollow column are evenly stressed during pressing, thereby improving the stability of the hollow column after gluing, eliminating the step of centering the hollow column, and improving work efficiency.

[0068] When the first screw 221 and the third screw 231 move, the second screw 222 drives the support plate 2222 to move in the opposite direction at the same time, thereby driving the inner support plate 251 to approach the inner wall of the hollow column. The inner support plate 251 and the clamping plate 24 are in contact with the hollow column at the same time, supporting the side plates of the hollow column, and preventing the position of the side plates from shifting when the hollow column is clamped, thereby reducing the defective rate and the waste of resources. The initial position of the inner support plate 251 can be changed by adjusting the screw 252, so that the device can be suitable for clamping and fixing hollow columns of different specifications, and has a wide range of applications.

[0069] After the hollow column is fixed, the hydraulic telescopic rod 31 is controlled to extend, and the extension of the hydraulic telescopic rod 31 drives the mounting plate 32 and the rolling roller 34 to approach the hollow column. When the pressure of the rolling roller 34 on the hollow column reaches a preset value, the extension of the hydraulic telescopic rod 31 is stopped, and then the second motor 41 is turned on, and the second motor 41 drives the third column gear 42 to rotate, and the rotation of the second column gear 42 drives the two fourth column gears 43 to rotate synchronously in the opposite direction, and with the cooperation of the rack 44, the movable seat 11 moves along the guide rail 1, and the second motor 41 is rotated forward and reversely to make the fixed assembly carry the hollow column to reciprocate along the guide rail 1, so that the rolling roller 34 applies pressure to different positions of the hollow column, and by applying pressure on the upper and lower sides of the hollow column synchronously, the connection between the upper and lower sides of the hollow column is subjected to more uniform force, and the hollow column is driven to reciprocate by the moving component, so that the force at different positions of the hollow column is uniform, thereby ensuring that the degree of fit at each position of the connection of the hollow column is consistent, so that the stability of the hollow column after gluing is better.

[0070] When the hollow column reciprocates, the friction force drives the rolling roller 34 to rotate, and the rolling roller 34 drives the rotating shaft 33 to rotate, thereby driving the cam 51 to rotate. The rotation of the cam 51 drives the piston rod 54 and the piston plate 53 to reciprocate up and down in the piston cylinder 52. The air flow blown out of the piston cylinder 52 is blown to the connection of the hollow column through the air guide pipe 56, which accelerates the coagulation of the glue at the connection, reduces the time waiting for the glue to coagulate, and improves the production efficiency of the hollow column.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
