Description

Technical Field

[0001] This invention relates to the field of bamboo strip production and processing technology, specifically to an automatic feeding device for bamboo strip rolls before forming. Background Technology

[0002] Moso bamboo is processed into bamboo strips through processes such as cutting, splitting, layering, and drawing. Then, bamboo strips of similar length and width are woven into a curtain-like structure, and the bamboo strip curtain is rolled into a bamboo roll. The bamboo roll is the raw material for preparing bamboo-wound composite products such as bamboo-wound composite pipes and bamboo-wound composite pipe corridors.

[0003] In existing technology, multiple bamboo strips are laid flat and glued together manually to form a long bamboo curtain. Because the joints of these strips are concentrated in one area, stress concentration occurs during production. Currently, there is no automated equipment for feeding bamboo strips during the forming process. This manual feeding method is limited by human energy and physical strength, resulting in a slow feeding speed that cannot keep up with the production pace and also increases the risk of finger injuries to workers. Summary of the Invention

[0004] In view of the existing technical problems, the present invention provides an automatic feeding device for bamboo strips before forming, so as to solve the problems of the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: An automatic feeding device for bamboo strips before forming the roll includes: The frame has a lower mounting plate and an upper mounting plate along the bamboo strip conveying direction; Multiple support pads are arranged in a straight line on the lower mounting plate and the upper mounting plate along the bamboo strip conveying direction. Each support pad has a raw material slot distributed along its width direction, and the bamboo strip bundle is supported in the raw material slot. Two sets of feeding components are respectively located at the front end of the lower mounting plate and the upper mounting plate. The two sets of feeding components are used to convey the bamboo strips on the lower mounting plate and the upper mounting plate forward. A flattening mechanism, located on the frame, is used to flatten the bamboo strips conveyed by the two sets of feeding components into a curtain shape.

[0006] In the above technical solution, bamboo strip bundles are placed in the raw material slots of the support pads on the lower and upper mounting plates, respectively. The bamboo strip bundles on the lower mounting plate are conveyed forward by their corresponding feeding components, and the bamboo strip bundles on the upper mounting plate are conveyed forward by their corresponding feeding components. The bamboo strips on the upper and lower mounting plates are conveyed together to the flattening mechanism and then laid flat into a curtain shape.

[0007] Preferably, the feeding assembly includes a mounting frame with multiple feed plates arranged side by side at intervals. The multiple feed plates are connected by bolts, and the gap between adjacent feed plates forms a feed groove. The feed groove corresponds one-to-one with the raw material slot. A baffle is inserted into the side of each feed groove facing the flattening mechanism. The baffle is provided with a feed slot opening that passes through the baffle along the bamboo strip conveying direction. The feed slot opening corresponds one-to-one with the feed groove and is connected to it. The mounting frame is equipped with a feeding roller located below the feeding trough. The bamboo strip bundles entering the feeding trough are fed into the feeding trough opening by the feeding roller.

[0008] In this scheme, the bamboo strip bundles located in the raw material slots will enter the feeding troughs formed between multiple feeding plates during the forward conveying process. The bottom layer of bamboo strips in the bamboo strip bundles that enter the feeding troughs will continue to be conveyed forward from the corresponding feeding trough openings under the action of the feeding rollers.

[0009] Preferably, the mounting bracket is provided with a pin, on which are distributed levers corresponding to the feed slots one by one. The levers extend into the corresponding feed slots and can rotate around the pin. The mounting bracket is provided with a position detection sensor corresponding to the position of each lever. When the lever rotates to the correct position, the position detection sensor will be triggered.

[0010] In this design, the lever initially extends into the feeding trough. As the bamboo bundle enters the feeding trough along the conveying direction, it pushes the lever to rotate the pin, lifting the lever. As the bamboo strips on the bamboo bundle are continuously conveyed forward, the height of the bamboo bundle in the feeding trough gradually decreases. At this time, the lever, which is lifted by the bamboo bundle, rotates in the opposite direction as the height of the bamboo bundle decreases. When the bamboo bundle descends to a certain height, the lever will rotate to a certain position, which will trigger the positioning detection sensor, prompting the staff to add material.

[0011] Preferably, the mounting frame is provided with a pressing cylinder in the vertical direction corresponding to each of the feeding slots. The lower end of the pressing cylinder is connected to a pressing plate. Under the action of the pressing cylinder, the pressing plate can extend into the corresponding feeding slot to press the bamboo strip bundle downward.

[0012] In this scheme, after the bamboo strip bundle enters the feeding trough, the pressing cylinder drives the pressing plate to move down and press the bamboo strip bundle located in the feeding trough, which facilitates the forward conveying of the bottom layer of bamboo strips one by one.

[0013] Preferably, the upper mounting plate is provided with conveying grooves that correspond one-to-one with and are connected to the feeding trough openings.

[0014] In this design, the feeding assembly on the lower mounting plate feeds the bamboo strips forward through the feeding slot and then into the corresponding conveying slot, where they continue to be conveyed forward.

[0015] Preferably, the paving mechanism includes a paving body, on which a first through groove and a second through groove are distributed. The first through groove corresponds to and is connected to the conveying groove, and the first through groove is inclined upward along the bamboo strip conveying direction. The second through groove corresponds to and is connected to the feeding slot on the feeding assembly located on the upper mounting plate, and the second through groove is inclined downward along the bamboo strip conveying direction. The first through groove and the second through groove are alternately distributed along the width direction of the paving body, and the bamboo strips are laid flat into a curtain shape after passing through the first through groove and the second through groove.

[0016] In this design, the bamboo strips coming out of the first slot will enter the first through slot, and the bamboo strips coming out of the second slot will enter the second through slot. Since the first through slot and the second through slot are distributed alternately along the width direction of the flat body, the bamboo strips coming out of the first through slot and the second through slot are laid flat to form a curtain shape along the width direction of the flat body.

[0017] Preferably, the tiling mechanism further includes a tiling feeding wheel assembly and a tiling feeding plate located at the front end of the tiling body, the tiling feeding plate being provided with a tiling feeding channel.

[0018] With this setup, the curtain-shaped bamboo strips, after being flattened by the flattening mechanism, are conveyed forward by the flattening feeding wheel set and continue to be conveyed out through the flattening feeding channel on the flattening feeding plate.

[0019] Preferably, the upper mounting plate has a notch in the middle, and a bamboo feeding wheel assembly is installed in the notch. The bamboo strips located in the conveying groove are conveyed forward by the bamboo feeding wheel assembly.

[0020] The bamboo strips that enter the feeding trough are conveyed forward by the drive of the bamboo feeding wheel assembly.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention conveys the bamboo strip bundles located on the lower mounting plate and the upper mounting plate forward respectively, and then conveys the bamboo strips on the bamboo strip bundles forward piece by piece in a staggered manner through the corresponding feeding components. The bamboo strips located on the upper mounting plate and the bamboo strips located on the lower mounting plate are conveyed together to the flattening mechanism and flattened into a curtain shape. Moreover, the joints of the bamboo strips are not in the same position, thus forming a staggered joint bamboo strip roll, thereby avoiding stress concentration. The invention realizes automatic feeding of bamboo strips before rolling, which greatly improves efficiency and operational safety, reduces the intensity of manual operation, and also reduces costs.

[0026] As attached Figure 1 - Appendix Figure 15 An automatic feeding device for bamboo strips before forming is shown, comprising: The frame 1 has a lower mounting plate 2 and an upper mounting plate 3 along the bamboo strip conveying direction. The planes on which the lower mounting plate 2 and the upper mounting plate 3 are located are parallel to the horizontal plane. The position of the lower mounting plate 2 is lower than the position of the upper mounting plate 3. The front end of the lower mounting plate 2 corresponds to the rear end of the upper mounting plate 3, that is, the lower mounting plate 2 and the upper mounting plate 3 have no overlapping parts. Multiple support pads 4 are respectively disposed on the lower mounting plate 2 and the upper mounting plate 3. The multiple support pads 4 are arranged in a straight line on the lower mounting plate 2 and the upper mounting plate 3 along the bamboo strip conveying direction. The support pads 4 have raw material slots 41 distributed along their width direction, and the bamboo strip bundles are supported in the raw material slots 41. Two sets of feeding components 5 are respectively located at the front end of the lower mounting plate 2 and the upper mounting plate 3. The two sets of feeding components 5 are respectively used to convey the bamboo strips on the lower mounting plate 2 and the upper mounting plate 3 forward one by one to the flattening mechanism 8. The flattening mechanism 8 is located on the frame 1 and in front of the feeding assembly 5 on the upper mounting plate 3, and is used to flatten the bamboo strips conveyed by the two sets of feeding assemblies 5 into a curtain shape.

[0027] refer to Figures 8-12 The feeding assembly 5 includes a mounting frame 50, on which multiple feeding plates 51 are arranged side by side at intervals. The multiple feeding plates 51 are connected by bolts, and the gaps between adjacent feeding plates 51 form feeding grooves 54. Each feeding groove 54 corresponds to a raw material slot 41. As the bamboo strip bundle is conveyed forward along the raw material slot 41, it enters the corresponding feeding groove 54. A baffle 510 is inserted into the side of each feeding groove 54 facing the flattening mechanism 8, and the baffle 510 is equipped with a feeding device. The feeding slot 53 extends through the baffle 510 along the bamboo strip conveying direction. The feeding slot 53 corresponds to and is connected to the feeding trough 54. The mounting frame 50 is equipped with a feeding roller 52, which is located below the feeding trough 54. The bottom layer of bamboo strips in the bamboo strip bundle entering the feeding trough 54 will contact the feeding roller 52. The feeding roller 52 will convey the bamboo strips in contact with it forward one by one. During the forward conveying process by the feeding roller 52, the bamboo strips will be sent out of the feeding assembly 5 through the feeding slot 53.

[0028] The mounting frame 50 is provided with a pin 560, which extends along the width of the feeding block 51 and is located above the feeding block 51. A lever 56, corresponding to each of the feeding grooves 54, is distributed on the pin 560. The lever 56 extends into the corresponding feeding groove 54 and can rotate around the pin 560. A position detection sensor 55 is provided on the mounting frame 50 corresponding to the position of each lever 56. When the lever 56 rotates to its correct position, it triggers the position detection sensor 55. As soon as the bamboo strip bundle enters the feeding groove 54, it pushes the lever 56 to rotate upwards. As the bamboo strips are fed forward piece by piece by the feeding roller 52, the height of the bamboo strip bundle decreases. At this time, the lever 56 rotates around the pin 560 as the bamboo strip bundle decreases in height. After rotating to a certain extent, it triggers the position detection sensor 55, indicating that the bamboo strip bundle has descended to its correct position and needs to be replenished.

[0029] The mounting frame 50 is equipped with a pressing cylinder 57 in the vertical direction corresponding to each of the feeding slots 54. The pressing cylinder 57 is located above the feeding block 51. The lower end of the pressing cylinder 57 is connected to a pressing plate 58. Under the action of the pressing cylinder 57, the pressing plate 58 can extend into the corresponding feeding slot 54 to press the bamboo strip bundles entering the feeding slot 54 downward, which is conducive to the bamboo strip bundles contacting the feeding roller 52 and feeding out the bamboo strips one by one.

[0030] refer to Figure 4 or Figure 6The upper mounting plate 3 has conveying grooves 31 that correspond one-to-one with and communicate with the feeding troughs 53. The conveying grooves 31 extend horizontally and penetrate the upper mounting plate 3 from front to back. The upper mounting plate 3 has a notch in the middle, and a bamboo feeding wheel set 6 is installed at the notch. The bamboo strips located in the conveying grooves 31 are conveyed forward by the bamboo feeding wheel set 6.

[0031] refer to Figure 5 , Figure 7 A discharge plate 7 is connected to the front side of the feeding assembly 5 located on the upper mounting plate 3. The discharge plate 7 has a plurality of first slots 71 and second slots 72 distributed on it. The plurality of first slots 71 are arranged in a straight line along the horizontal direction, and the plurality of second slots 72 are arranged in a straight line along the horizontal direction. The plurality of first slots 71 correspond one-to-one with the conveying groove 31 and are connected. The plurality of second slots 72 correspond one-to-one with the feeding slot 53 on the feeding assembly 5 located on the upper mounting plate 3 and are connected. The first slots 71 and second slots 72 are arranged alternately and sequentially along the width direction of the discharge plate 7.

[0032] refer to Figure 13-15 , Figure 5 and Figure 7 The paving mechanism 8 includes a paving body, a paving feeding wheel set 80 and a paving feeding plate 85 located at the front end of the paving body. The paving feeding plate 85 is provided with a paving feeding channel 86. The paving body is provided with a first through groove 82 and a second through groove 84. The first through groove 82 corresponds to and communicates with the first slot 71. The first through groove 82 is inclined upward along the bamboo strip conveying direction. The second through groove 84 corresponds to and communicates with the second slot 72. The second through groove 84 is inclined downward along the bamboo strip conveying direction. The first through groove 82 and the second through groove 84 are distributed alternately along the width direction of the paving body. After the bamboo strips pass through the first through groove 82 and the second through groove 84, they are laid flat into a curtain shape.

[0033] In this embodiment, the flattening body includes a first plate 81 and a second plate 83. The first plate 81 is located below the second plate 83. A connecting plate is connected to each side of the first plate 81 and the second plate 83. The lower ends of the connecting plates on both sides are fixed to the frame 1. The rear ends of the first plate 81 and the second plate 83 are connected to the discharge plate 7, and their front ends face the flattening feeding wheel group 80. The first through groove 82 is located inside the first plate 81, and the second through groove 84 is located inside the second plate 83. The upper edge of the front end of the first plate 81 contacts the lower edge of the front end of the second plate 83. Since the first through groove 82 and the second through groove 84 are distributed alternately along the width direction of the flattening body, the bamboo strips are flattened into a curtain shape after being fed out through the first through groove 82 and the second through groove 84.

[0034] The working principle of this invention is as follows: refer to Figure 16 and Figure 17 In the diagram, only one of the raw material slots 41 of the support pad 4 contains a bundle of bamboo strips; in practice, multiple bundles can be placed depending on the specific situation. The terms "front" and "back" in this design are defined relative to the direction of bamboo strip transport.

[0035] First, the bamboo strip bundles are tied with clips and, after sugar removal and drying, placed in the raw material slots 41 on the upper mounting plate 3 and the lower mounting plate 2 respectively. The pushing mechanism 9 is activated, and the pusher plate 92 pushes the bamboo strip bundles on the lower mounting plate 2 forward. When the bamboo strip bundles enter the feeding groove 54 on the feeding assembly 5 on the lower mounting plate 2, it pushes the corresponding lever 56 to rotate upward. Then, the corresponding pressing cylinder 57 drives the pressing plate 58 to move downward, pressing the bamboo strip bundles tightly so that the bottom of the bamboo strip bundles contacts the feeding roller 52. The feeding roller 52 then feeds the bamboo strips in contact with it forward one by one through the feeding slot 53. The bamboo strips fed from the feeding slot 53 enter the conveying groove 31 in the upper mounting plate 3, and are then further fed by the bamboo feeding wheel assembly 6. Forward conveying: The bamboo strip bundles in the raw material slots 41 on the upper mounting plate 3 enter the corresponding feeding components 5 and are also fed out piece by piece from the feeding slots 53 and enter the second channel 84 of the flattening mechanism 8 to continue forward conveying. The bamboo strips fed out from the conveying slots 31 enter the first channel 82 of the flattening mechanism 8 to continue forward conveying. Since the first channel 82 and the second channel 84 are staggered along the width direction of the flattening mechanism 8, the bamboo strips coming out of the first channel 82 and the second channel 84 are arranged side by side in the width direction of the flattening mechanism 8 to form a curtain. The flattened bamboo strips are conveyed forward by the flattening feeding wheel group 80 and then sent out through the flattening feeding channel 86 on the flattening feeding plate 85.

[0036] The preferred embodiments of the present invention have been described above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
