[0027] 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.
[0028] Please refer to Figures 1 to 6 As shown, the present invention provides a bamboo board heating device, including a transmission channel 1. The transmission channel 1 is divided into at least two shaping areas along its own transmission direction. The shaping areas are arranged with alternating transmission belts 2 and heaters 3 along the transmission direction perpendicular to the transmission channel 1. The transmission belts 2 and heaters 3 between adjacent shaping areas are staggered.
[0029] Working principle: Bamboo strips 7 are initially assembled into bamboo boards and fed into the conveyor channel 1. Utilizing the limited space of the conveyor channel 1, the bamboo boards are flattened so that the long sides of each bamboo strip 7 are at the same horizontal level. Because the conveyor belt 2 and heater 3 are staggered between adjacent shaping areas, thus… Figure 6 As shown, the bamboo board surface can be divided into alternating first pressing surfaces 8 and second pressing surfaces 9. Taking the shaping operation of the bamboo board in two shaping areas as an example, when the bamboo board enters one of the shaping areas along the conveying direction, the conveyor belt 2 of the shaping area applies a driving force to the first pressing surface 8 of the bamboo board, and the heater 3 of the shaping area can heat the second pressing surface 9 of the bamboo board, so that the glue on the second pressing surface 9 is cured by heat. When the bamboo board continues to move along the conveying direction into the other shaping area, the conveyor belt 2 of the shaping area applies a driving force to the second pressing surface 9 of the bamboo board, and the heater 3 of the shaping area can heat the first pressing surface 8 of the bamboo board, so that the glue on the first pressing surface 8 is cured by heat, thereby completing the heating and shaping of the bamboo board.
[0030] It is worth noting that the transmission speed is the same in each of the shaping areas to ensure smooth transmission of the bamboo board in transmission channel 1.
[0031] Please refer to Figure 1 and Figure 2 As shown, the transmission belt 2 further includes a first transmission belt 21 and a second transmission belt 22 with their transmission surfaces facing each other and spaced apart; the heater 3 is located on the side of the first transmission belt 21 and / or the second transmission belt 22.
[0032] As described above, the first conveyor belt 21 and the second conveyor belt 22 apply force to the upper and lower surfaces of the bamboo board, which not only ensures the transmission of the bamboo board, but also flattens the bamboo strips 7 under the squeezing action of the transmission surfaces of the first conveyor belt 21 and the second conveyor belt 22, so that the long sides of adjacent bamboo strips 7 can be at the same horizontal height.
[0033] It is worth noting that, in order to ensure the stability of the bamboo board conveying process, the rotation direction of the first conveyor belt 21 is opposite to that of the second conveyor belt 22. The conveying speed of the first conveyor belt 21 is the same as that of the second conveyor belt 22.
[0034] Please refer to Figure 2 and Figure 3 As shown, further, a floating pressure block 4 is abutted against the inner side of the transmission surface of the transmission belt 2.
[0035] As can be seen from the above description, by controlling the channel size of the transmission channel 1 to be slightly smaller than the thickness of the bamboo board, and by utilizing the movement of the floating pressure block 4, the transmission surface of the transmission belt 2 can be made to closely adhere to the bamboo board, thereby ensuring the stable transmission of the bamboo board.
[0036] It is worth noting that the floating pressure block 4 is connected to a cylinder, and the pressure of the cylinder controls the clamping force on the floating pressure block 4. Of course, the clamping force of the floating pressure block 4 can also be controlled by connecting a hydraulic cylinder and a spring.
[0037] Please refer to Figure 3 As shown, the floating pressure block 4 further comprises a plurality of pressure blocks 41 arranged along the conveying surface of the conveyor belt 2.
[0038] As can be seen from the above description, since the degree of curvature of each bamboo strip 7 is not uniform, by setting multiple independent floating pressure blocks 41, it is possible to ensure that the force on each bamboo strip 7 is as uniform as possible, so as to avoid the bamboo strip 7 from separating and causing the bamboo board to break.
[0039] Please refer to Figure 2 and Figure 3 As shown, further, the inner side of the transmission surface of the transmission belt 2 is abutted against a support beam 5.
[0040] As described above, since the conveying surface of the conveyor belt 2 is flexible and the curvature of each bamboo strip 7 is not uniform, there is uneven contact between each bamboo strip 7 and the conveying surface of the conveyor belt 2. Therefore, by using the support beam 5 to support the conveying surface of the conveyor belt 2, it is possible to ensure that the amount of contact between each bamboo strip 7 and the conveying surface of the conveyor belt 2 is as consistent as possible.
[0041] In some embodiments, the floating pressure block 4 and the support beam 5 are respectively abutted against the inner sides of the transmission surfaces of the first conveyor belt 21 and the second conveyor belt 22. By controlling the distance between the first conveyor belt 21 and the second conveyor belt 22 to be slightly less than the thickness of the bamboo board, the movement of the floating pressure block 4 and the support of the support beam 5 ensure that the transmission surfaces of the first conveyor belt 21 and the second conveyor belt 22 are in close contact with the bamboo board, thus ensuring stable transmission of the bamboo board. Furthermore, the transmission resistance of this method is lower than that of a method where support beams 5 are provided on the inner sides of the transmission surfaces of both the first conveyor belt 21 and the second conveyor belt 22.
[0042] Please refer to Figure 3 and Figure 5 As shown, in some embodiments, the conveyor belt 2 is a chain conveyor belt, and a support block 23 is provided on the chain of the conveyor belt 2. Since the conveyor belt 2 is a chain conveyor belt, when the floating pressure block 4 and the support beam 5 are set, the floating pressure block 4 and the support beam 5 can be pressed against the rollers of the chain, so that there is rolling friction between the floating pressure block 4 and the support beam 5 and the transmission surface of the conveyor belt 2, thereby reducing the transmission resistance of the conveyor belt 2. Then, the conveyor belt 2 contacts the bamboo board surface through the support block 23, thereby ensuring the smooth transmission of the bamboo board.
[0043] In some embodiments, the support surface of the support block 23 is provided with anti-slip protrusions. The anti-slip protrusions are used to prevent slippage between the support block 23 and the bamboo board surface.
[0044] Please refer to Figure 1 , Figure 2 and Figure 4 As shown, the bamboo board heating device also includes a lifting device 6, the movable end of which is connected to a first conveyor belt 21 and / or a second conveyor belt 22.
[0045] As described above, the distance between the first conveyor belt 21 and the second conveyor belt 22 is controlled by the lifting device 6, so that the conveyor belt 2 can adapt to the transmission of bamboo boards of various thicknesses.
[0046] Please refer to Figure 5 As shown, the height difference between the heating end face of the heater 3 and the transmission surface of the conveyor belt 2 is A, where 0mm≤A≤10mm.
[0047] As can be seen from the above description, limiting the height difference between the heating end face of the heater 3 and the transmission surface of the conveyor belt 2 not only ensures the smooth transmission of the bamboo board, but also ensures the heating of the glue between the bamboo strips 7.
[0048] 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.
