Detailed implementation manners

[0019] The following will describe in detail specific embodiments of the present invention with reference to the accompanying drawings.

[0020] As Figure 1 、 2 、shown in FIG. 3, it is a specific embodiment of the bamboo strip synchronous automatic lengthening device and method of the present invention. The lengthening method of this embodiment adopts a lengthening device, and the lengthening device includes a plurality of lengthening units 0 connected end to end. The lengthening unit 0 includes a frame 1, a feeding groove 2, a material shifting mechanism 3 and a hot pressing mechanism 4. The feeding groove 2, the material shifting mechanism 3 and the hot pressing mechanism 4 are arranged on the frame 1. The feeding groove 2 is set as a plurality of parallel rows for the bamboo strips to be transported and stored from the previous process. The material shifting mechanism 3 is located at one end of the feeding groove 2. The material shifting mechanism 3 includes a material shifting table 31, a pressing groove 32 and a pressing block 33. The pressing groove 32 and the pressing block 33 are arranged on the material shifting table 31. The pressing groove 32 corresponds to the feeding groove 2 for the bamboo strips to be transported and stored. The pressing block 33 and the pressing groove 32 are vertically corresponding. The pressing block 33 is movably arranged and presses and limits the bamboo strip when it descends into the pressing groove 32. The material shifting table 31 is movably arranged on the frame 1 to adjust the end position of the bamboo strip when the bamboo strip is pressed and translated. The hot pressing mechanism 4 at each lengthening unit 0 receives the ends of the front and rear bamboo strips and hot presses and lengthens the front and rear bamboo strips;

[0021] The lengthening method includes the following steps:

[0022] S1: Multiple groups of bamboo strips that have completed end notching and gluing are sequentially fed into a plurality of lengthening units 0 connected end to end through a feeding device. The number of groups of bamboo strips corresponds to the number of lengthening units 0;

[0023] S2: The bamboo strips in each group of lengthening units 0 are clamped by the material shifting mechanism 3. The material shifting mechanisms 3 in each group of lengthening units 0 operate sequentially in the front-rear order, so that the ends of the bamboo strips are translated to the adjacent hot pressing mechanism 4, and the ends of the front and rear bamboo strips are engaged at the hot pressing mechanism 4;

[0024] S3: Each group of hot pressing mechanisms 4 operates to synchronously heat and cure the end joint parts of multiple groups of bamboo strips, so that multiple groups of bamboo strips are synchronously lengthened.

[0025] When the present invention is in use, the number of lengthening units 0 is set according to the length of the bamboo strips to be lengthened, such as Figure 3As shown, the lengthening units 0 are connected end to end, and the length of each lengthening unit 0 is approximately equal to the length of the bamboo strips to be lengthened. First, the bamboo strips are notched and glued at the ends, and then conveyed to the lengthening unit 0 by the feeding device. The number of bamboo strips conveyed in each batch corresponds to the number of lengthening units 0. Then, the feeding device pushes the corresponding number of bamboo strips into the corresponding number of lengthening units 0. Specifically, the bamboo strips are placed in the feeding trough 2, and the size of the feeding trough 2 is adapted to the bamboo strips, so as to limit the bamboo strips well and facilitate the alignment of the front and rear bamboo strips. Each group of lengthening units 0 is arranged in parallel with multiple feeding troughs 2. After connecting to the previous equipment, the conveying and hot pressing processes of the bamboo strips can be carried out simultaneously in the same batch, improving the processing efficiency. Then, the material transfer mechanism 3 works. On the one hand, it clamps and stabilizes multiple bamboo strips, and on the other hand, it displaces to accurately align the ends of the bamboo strips to the hot pressing mechanism 4. Specifically, the material transfer mechanisms 3 of each group of lengthening units 0 operate in sequence. That is, the first group of material transfer mechanisms 3 operates to clamp the first group of bamboo strips and translate the ends to the hot pressing mechanism 4. The front ends of the bamboo strips in the first group can be restricted by the previous batch of bamboo strips in front, so as to well limit the stopping position. Then, as the subsequent groups of material transfer mechanisms 3 operate, the subsequent groups of bamboo strips are all in contact with the hot pressing mechanism 4 at the ends to achieve neat and tight meshing. Among them, the size of the pressing groove 32 is adapted to the bamboo strips, so as to limit the bamboo strips well and facilitate the alignment of the front and rear bamboo strips. After the pressing block 33 descends into the pressing groove 32, it presses the bamboo strips from above, forming stable clamping and limiting for the bamboo strips. The material transfer table 31 can be translated on the frame 1, and multiple pressing grooves 32 are arranged in parallel on it, and the clamping and translation of the bamboo strips can be carried out simultaneously in the same batch. Each group of hot pressing mechanisms 4 completes heating and curing at the end positions of the front and rear bamboo strips to be hot pressed, realizing the mechanized and automated synchronous lengthening of multiple bamboo strips. After the processing of this batch of bamboo strips is completed, when the next batch of bamboo strips is conveyed into this device, it can push the bamboo strips to the next process to realize overall discharging. The next batch of bamboo strips repeats the overall lengthening method, thus realizing the mechanized and automated synchronous lengthening of multiple bamboo strips.

[0026] As an improved specific implementation manner, it further includes step S4: repeating steps S1, S2, and S3 to synchronously lengthen the bamboo strips multiple times.

[0027] When this implementation manner is applied, a group of hot pressing mechanisms 4 set at the corresponding stopping positions of the front and rear batches of bamboo strips can be used to further lengthen the bamboo strips, so as to achieve the processing effect of infinitely lengthening the required bamboo strips. The lengthened bamboo strips can be conveyed to the subsequent processes to complete operations such as fixed-length cutting, and then the bamboo strips can be adaptively processed according to the requirements of the processed products.

[0028] As an improved specific implementation manner, the feeding trough 2 includes a bottom trough 21 and an upper plate 22. The bottom trough 21 confines the bamboo strips therein and conveys and stores them along its length direction. The upper plate 22 is arranged above the bottom trough 21, and a passage for the bamboo strips to pass through is formed between the upper plate 22 and the bottom trough 21.

[0029] As shown in Figure 1 , 2 shown, the side wall of the bottom groove 21 adapts to the width of the bamboo strip, thereby performing effective limiting and stabilizing the transportation of the bamboo strip along the length direction. When the bamboo strip is relatively long, it will generate a certain bending state. By arranging an upper plate 22 above the bottom groove 21, a channel for the bamboo strip to pass through is formed by the cooperation of the bottom groove 21 and the upper plate 22, which can effectively avoid the natural bending of the bamboo strip during transportation and make the transportation more orderly.

[0030] As an improved specific implementation manner, the material transfer mechanism 3 further includes a material transfer cylinder 35. Both sides of the material transfer table 31 are slidably arranged on the tracks on both sides of the frame 1. The material transfer cylinder 35 is arranged on the frame 1 and connected to the material transfer table 31. When the material transfer cylinder 35 works, it drives the material transfer table 31 to translate to adjust the end position of the bamboo strip.

[0031] As shown in Figure 1 , 2 shown, the number of the material transfer table 31 and the matching pressing grooves 32 is set wider to meet the requirements of transporting and clamping multiple bamboo strips. Both sides of it are arranged on the tracks on both sides of the frame 1 through sliders, and it can stably translate along the bamboo strip transportation direction; the translation power of the material transfer table 31 is provided by the material transfer cylinder 35. The use of the material transfer cylinder 35 not only stably realizes the translation of the material transfer cylinder 35, but also provides a pressing force for the docking position of the front and rear bamboo strips, ensuring the stable meshing of the docking position of the bamboo strips, ensuring the flatness of the hot pressing and lengthening, and ensuring the processing quality.

[0032] As an improved specific implementation manner, the material transfer mechanism 3 further includes a material transfer motor 34. The material transfer motor 34 is arranged on the upper frame of the material transfer table 31 and connected to the pressing block 33. When the material transfer motor 34 works, it drives the pressing block 33 to lift and lower.

[0033] As shown in Figure 1 , 2 shown, a frame is erected according to the width of the material transfer table 31, and an appropriate number of material transfer motors 34 are arranged at intervals on the frame. The pressing blocks 33 are arranged at intervals below the material transfer motors 34. When the material transfer motors 34 work, they drive the pressing blocks 33 to lift and lower, and rely on the downward pressure of the material transfer motors 34 to keep the bamboo strips in the pressing grooves 32 clamped and stable.

[0034] As an improved specific implementation manner, the hot pressing mechanism 4 includes a hot pressing groove 41, a hot pressing member 42 and a hot pressing motor 43. The hot pressing groove 41 limits the bamboo strip therein and transports and stores it along its length direction. The hot pressing member 42 and the hot pressing groove 41 are corresponding up and down. The hot pressing motor 43 is arranged on the upper frame of the frame 1 and connected to the hot pressing member 42. When the hot pressing motor 43 works, it drives the hot pressing member 42 to lift and lower.

[0035] As shown in Figure 1As shown in the figure, the number of hot pressing grooves 41 is set according to the number of bamboo strips hot pressed in parallel in a single batch by the splicing unit 0, and its width is adapted to the width of the bamboo strips, so that when the bamboo strips are conveyed into the hot pressing grooves 41, they are well limited, which is beneficial to the alignment and engagement of the end joints of the front and rear bamboo strips; a groove structure is arranged on the hot pressing member 42 to adapt to the shape of the bamboo strips, and the groove structure and the hot pressing grooves 41 cooperate to form an upper and lower pressing structure to act on the end positions of the bamboo strips to be hot pressed; a frame is erected according to the width of the frame 1, and an appropriate number of hot pressing motors 43 are arranged at intervals on the frame. The hot pressing member 42 is arranged below the hot pressing motor 43. When the hot pressing motor 43 works, it drives the hot pressing member 42 to lift and lower. By relying on the downward pressure of the hot pressing motor 43, the bamboo strips are pressed and stabilized by the hot pressing grooves 41 and the hot pressing member 42. When the hot pressing grooves 41 and the hot pressing member 42 are heated by a heat source, the heating and splicing process of the bamboo strips is completed.

[0036] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
