Description

Technical Field

[0001] This utility model relates to the field of bamboo board production technology, and in particular to a bamboo board splicing device. Background Technology

[0002] Because bamboo is cylindrical, it is usually necessary to cut the whole bamboo into bamboo tubes, and then split the bamboo tubes longitudinally into 2-6 pieces with an arc-shaped cross-section. The bamboo is then processed by removing the outer nodes and the inner nodes, heating and softening it before being rolled and flattened to obtain bamboo strips. To splice these bamboo strips into bamboo boards, a continuous differential speed splicing device is disclosed in CN214293563U, which utilizes the speed difference between the front and rear conveying mechanisms to achieve automated splicing and transmission of the boards. However, due to the high elasticity of bamboo fibers and uneven stress during rolling, each flattened bamboo strip exhibits varying degrees of bending. If differential speed splicing is used directly, overlap between the edges of the bamboo strips can easily occur, affecting subsequent processes. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a bamboo board splicing device to ensure the splicing quality between bamboo strips.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a bamboo board splicing device, including a first transmission belt and a second transmission belt with their transmission surfaces facing each other and spaced apart, wherein a floating pressure block abuts against the inner side of the transmission surface of the first transmission belt; and a support beam abuts against the inner side of the transmission surface of the second transmission belt.

[0005] Furthermore, the floating pressure block has multiple pressure blocks arranged along the conveying direction of the first conveyor belt.

[0006] Furthermore, the aforementioned bamboo board splicing device also includes a lifter, the movable end of which is connected to a first conveyor belt and / or a second conveyor belt.

[0007] Furthermore, the aforementioned bamboo board splicing device also includes a third and a fourth conveyor belt with their conveying surfaces facing each other and spaced apart.

[0008] The third and fourth conveyor belts are respectively connected to the feed ends of the first and second conveyor belts.

[0009] Furthermore, the distance between the third and fourth transmission belt surfaces is greater than or equal to the distance between the first and second transmission belt surfaces.

[0010] Furthermore, the length of the third transmission belt is greater than the length of the fourth transmission belt.

[0011] Furthermore, the length of the third transmission belt is 1.3 to 2 times the length of the fourth transmission belt.

[0012] Furthermore, the aforementioned bamboo board splicing device also includes a lifter, the movable end of which is connected to a third conveyor belt and / or a fourth conveyor belt.

[0013] Furthermore, both the first and second conveyor belts are chain conveyor belts or track conveyor belts, and the chain conveyor belt has support blocks on its chain.

[0014] Furthermore, the support surface of the support block is provided with anti-slip protrusions.

[0015] The beneficial effects of this utility model are as follows: by controlling the distance between the first conveyor belt and the second conveyor belt to be slightly less than the thickness of the bamboo board, when the front conveyor belt feeds the bamboo strip between the first conveyor belt and the second conveyor belt, the movement of the floating pressure block and the support of the support beam are used to make the transmission surface of the first conveyor belt and the transmission surface of the second conveyor belt fit tightly against the bamboo strip and flatten the bamboo strip, thereby avoiding the overlap between the bamboo strips.

[0023] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0024] Please refer to Figures 1 to 3As shown, a bamboo board splicing device includes a first conveyor belt 1 and a second conveyor belt 2 with their conveyor surfaces facing each other and spaced apart. A floating pressure block 11 abuts against the inner side of the conveyor surface of the first conveyor belt 1; and a support beam 21 abuts against the inner side of the conveyor surface of the second conveyor belt 2.

[0025] Working principle: By controlling the distance between the first conveyor belt 1 and the second conveyor belt 2 to be slightly less than the thickness of the bamboo board, when the front conveyor belt feeds the bamboo strip 6 between the first conveyor belt 1 and the second conveyor belt 2, the movement of the floating pressure block 11 and the support of the support beam 21 are used to make the transmission surface of the first conveyor belt 1 and the transmission surface of the second conveyor belt 2 fit tightly against the bamboo strip 6 and flatten the bamboo strip 6, thereby avoiding the overlap between the bamboo strips 6.

[0026] It is worth noting that, in order to ensure the stability of the bamboo strip 6 conveying process, the rotation direction of the first conveyor belt 1 is opposite to that of the second conveyor belt 2. The conveying speed of the first conveyor belt 1 is the same as that of the second conveyor belt 2.

[0027] Please refer to Figure 3 As shown, the floating pressure block 11 further comprises a plurality of pressure blocks 111 arranged along the transmission direction of the first conveyor belt 1.

[0028] As can be seen from the above description, since the curvature of each bamboo strip 6 is not uniform, by setting multiple independent floating pressure blocks 111, it is possible to ensure that the force on each bamboo strip 6 is as uniform as possible, so as to avoid the inconsistent transmission speed of the bamboo strip 6 between the first conveyor belt 1 and the second conveyor belt 2, which would affect the continuity of the spliced ​​bamboo board.

[0029] Please refer to Figure 1 and Figure 2 As shown, the bamboo board splicing device further includes a lifting device 3, the movable end of which is connected to a first conveyor belt 1 and / or a second conveyor belt 2.

[0030] As described above, the distance between the first conveyor belt 1 and the second conveyor belt 2 is controlled by the lifting device 3, thereby adapting to flattening bamboo strips 6 of various thicknesses.

[0031] Please refer to Figure 1 As shown, the bamboo board splicing device further includes a third conveyor belt 4 and a fourth conveyor belt 5 with their conveying surfaces facing each other and spaced apart. The third conveyor belt 4 and the fourth conveyor belt 5 are respectively connected to the feeding ends of the first conveyor belt 1 and the second conveyor belt 2.

[0032] As described above, by applying force to the upper and lower surfaces of the bamboo strip 6 using the third conveyor belt 4 and the fourth conveyor belt 5, not only is the transmission of the bamboo strip 6 ensured, but the bamboo strip 6 is also pre-flattened under the squeezing action of the transmission surfaces of the third conveyor belt 4 and the fourth conveyor belt 5, ensuring the subsequent splicing of bamboo boards.

[0033] It is worth noting that, in order to ensure the stability of the bamboo board conveying process, the rotation direction of the third conveyor belt 4 is opposite to that of the fourth conveyor belt 5.

[0034] Please refer to Figure 1 As shown, in some embodiments, the distance between the transmission surfaces of the third conveyor belt 4 and the fourth conveyor belt 5 is greater than or equal to the distance between the transmission surfaces of the first conveyor belt 1 and the second conveyor belt 2. Furthermore, the length of the third conveyor belt 4 is greater than the length of the fourth conveyor belt 5. Setting the transmission speed of the third conveyor belt 4 to be greater than the transmission speed of the fourth conveyor belt 5 allows the bamboo strip 6 to move between the third conveyor belt 4 and the fourth conveyor belt 5. Because the upper and lower surfaces of the bamboo strip 6 experience different driving speeds, the transmission speed of the bamboo strip 6 tends to be the average of the speeds of the upper and lower surfaces. That is, the transmission speed of the bamboo strip 6 is less than the transmission speed of the bamboo strip 6 that does not move between the third conveyor belt 4 and the fourth conveyor belt 5, thereby achieving pre-splitting of the bamboo strip 6 on the third conveyor belt 4.

[0035] Preferably, the length of the third conveyor belt 4 is 1.3 to 2 times the length of the fourth conveyor belt 5, to ensure sufficient transmission distance for the pre-splicing of the bamboo strips 6.

[0036] Furthermore, the bamboo board splicing device described above also includes a lifter (not shown in the figure), the movable end of which is connected to a third conveyor belt 4 and / or a fourth conveyor belt 5.

[0037] As described above, the distance between the third conveyor belt 4 and the fourth conveyor belt 5 is controlled by the lifting device, thereby accommodating the pre-flattening of bamboo strips 6 of various thicknesses.

[0038] Furthermore, both the first conveyor belt 1 and the second conveyor belt 2 are chain conveyor belts or track conveyor belts, and the chain conveyor belt has support blocks on its chain.

[0039] As described above, the bamboo strips 6 are transported by a chain conveyor belt or a crawler conveyor belt. When using a chain conveyor belt to transport the bamboo strips 6, a support block needs to be provided on the chain so that the support block contacts the surface of the bamboo strips 6.

[0040] It is worth noting that when setting the floating pressure block 11 and the support beam 21, it is preferable to use a chain conveyor belt, so that the floating pressure block 11 and the support beam 21 can be pressed against the rollers of the chain, so that the floating pressure block 11 and the support beam 21 are rolling friction with the chain, thereby reducing the transmission resistance of the conveyor belt.

[0041] Furthermore, the support surface of the support block is provided with anti-slip protrusions.

[0042] As can be seen from the above description, anti-slip protrusions are used to prevent slippage between the support block and the bamboo strip 6.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
