Technical Field

[0001] This invention relates to a feeding device for a reconstituted bamboo strip weaving machine with a flipping function, belonging to the field of bamboo strip weaving. Background Technology

[0002] Reconstituted bamboo, as a high-performance and environmentally friendly material, is made by processing bamboo into bamboo strips and then weaving, gluing, and pressing them. It features high strength, durability, and high resource utilization, and its application in construction, furniture, and decoration is becoming increasingly widespread. Reconstituted bamboo strip weaving is one of the core processes in reconstituted bamboo production; the degree of automation, continuity, and stability of the feeding process directly affects the subsequent weaving quality and production efficiency.

[0003] Currently, there are still many technical bottlenecks in the feeding operation of reconstituted bamboo strip weaving machines: traditional feeding methods rely heavily on manual feeding, which is not only labor-intensive and costly, but also makes it difficult to screen the quality of bamboo strips (for example, incomplete surface processing of bamboo strips, resulting in protrusions), leading to a reduction in the quality of finished bamboo products. Therefore, it is necessary to improve it. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems in the background art and to provide a feeding device for a reconstituted bamboo strip weaving machine with a flipping function.

[0005] The present invention achieves the above objectives by adopting the following technical solution:

[0006] A feeding device for a reconstituted bamboo strip weaving machine with a flipping function includes a storage container, a limiting device, a feeding device, and a screening device; the storage container, feeding device, and screening device are sequentially connected and fixedly connected to a base plate; the limiting device is located on the outside of the feeding device. Compared with the prior art, the beneficial effects of this invention are: this invention can not only automatically feed bamboo strips, reducing manual labor and saving manpower, but also detect whether there are protrusions in the bamboo strips and discharge bamboo strips with protrusions, avoiding problems such as bamboo products not being firmly pressed due to protrusions, thus affecting the quality of bamboo products.

Obviously, the described embodiments are only some embodiments of the invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Specific implementation method one: as follows Figures 1-14 As shown, this embodiment describes a feeding device for a reconstituted bamboo strip weaving machine with a flipping function, including a storage container 1, a limiting device 2, a feeding device 3, and a screening device 4; the storage container 1, the feeding device 3, and the screening device 4 are sequentially connected and fixedly connected to the base plate 6; the limiting device 2 is located on the outside of the feeding device 3.

[0023] The storage device 1 includes a collection box 11; a return spring 12 is fixedly connected to the bottom surface inside the collection box 11; a sliding plate 13 that slides with the collection box 11 is fixedly connected to the return spring 12; multiple bamboo strips 5 are placed on the sliding plate 13; a bracket is fixedly connected to the side of the collection box 11, and a conveyor cylinder 14 is fixedly connected to the upper end of the bracket.

[0024] The feeding device 3 includes a cylindrical body composed of two opposing arc-shaped outer shells 31; an arc-shaped baffle 32 is fixedly connected to the outer wall of each outer shell 31 near the storage container 1, and an arc-shaped groove 38 is provided on the inner wall of the outer shell 31 away from the storage container 1; a limiting groove 35 communicating with the groove 38 is also provided on the inner wall of the outer shell 31; the limiting groove 35 is interference-fitted with the limiting block 37, and the groove 38 is slidably fitted with the limiting block 37; an elastic telescopic rod I 36 is fixedly connected to the inner wall of the limiting groove 35, and the free end of the elastic telescopic rod I 36 is abutted against the limiting block 37; a plurality of conveying structures I 33 are also provided on the inner wall of the outer shell 31; a through hole is provided on the side of the outer shell 31 near the groove 38, and the through hole is slidably fitted with the conveying structure II 34. The limiting block 37 is interference-fitted with the limiting groove 35. After the limiting block 37 is located in the limiting groove 35 and compresses the elastic telescopic rod I 36, in the corresponding state, the elastic telescopic rod I 36 pushes the limiting block 37 to slowly disengage from the limiting groove 35, so as to avoid the limiting block 37 being located at the connection between the groove 38 and the limiting groove 35, which would affect the discharge of the bamboo strip 5.

[0025] Each of the conveying structures I33 includes a U-shaped frame I333; a central shaft I331 is fixedly connected to the inner wall of the U-shaped frame I333, and a roller I332 is sleeved on the central shaft I331; the U-shaped frame I333 is provided with a through hole that slides with a connecting rod I335, one end of the connecting rod I335 is fixedly connected to a stop block 334, and the other end of the connecting rod I335 is fixedly connected to the inner wall of the outer casing 31; a spring I336 is also provided between the U-shaped frame I333 and the inner wall of the outer casing 31 and is sleeved on the connecting rod I335.

[0027] The central shaft I 331, the central shaft II 341, and the side of the transmission cylinder 14 are all equipped with power devices, such as drive motors.

[0028] The limiting device 2 includes a limiting cylinder 21 sleeved on the outside of the outer shell 31; the side of the limiting cylinder 21 is fixedly connected to the free end of the elastic telescopic rod II 24; the fixed end of the elastic telescopic rod II 24 is fixedly connected to the side of the baffle 32; the inner wall of the limiting cylinder 21 is provided with a slot 22 that slides with the corresponding connecting rod II 344; the limiting cylinder 21 is fixedly connected to the base plate 6 by a fixing rod 23.

[0029] The screening device 4 includes a rotating drum 41; one end of the rotating drum 41 is located inside the outer shell 31, and the other end of the rotating drum 41 is connected to the inner wall of the limiting ring 45 via a bearing; the limiting ring 45 is connected to the base plate 6 via a rod 46; a side plate 42 with a feed inlet 421 is fixedly connected to the side of the rotating drum 41 near the outer shell 31; symmetrical slides 441 are provided on the outer wall of the rotating drum 41, and each slide 441 has a U-shaped groove 442 communicating with it on its side; the limiting block 37 slides in cooperation with the corresponding slide 441 and groove 442; the groove The end of 442 away from the limiting ring 45 is connected to the slide rail 441 by a spring hinge with a limiting rod 443; the outer wall of the rotating cylinder 41 is provided with a connecting hole, and the connecting hole is connected to a rotating rod 444 through a bearing; multiple arc-shaped protrusions 446 are fixedly connected to the bottom of the outer wall of the rotating rod 444; a limiting hole 441 is provided on the inner wall of the connecting hole; a locking block 413 is connected to the inner wall of the limiting hole 411 through a spring III 412; the locking block 413 contacts the corresponding protrusion 446; multiple transmission rods 445 are fixedly connected to the top side of the rotating rod 444.

[0030] A conveying bucket 43 is connected to the inner wall of the rotating drum 41 via a bearing, and the other end of the conveying bucket 43 is fixedly connected to the output shaft of the fixed motor 47; the fixed motor 47 is connected to the inner wall of the rotating drum 41 via a mounting base.

[0031] When the locking block 413 contacts the side wall of the corresponding protrusion 446, one of the transmission rods 445 is located in the slide groove 442 and the other transmission rod 445 is located in the slide groove 441.

[0032] The feed inlet 421 is located at an eccentric position on the side baffle 42; the bamboo strips 5 conveyed by the feeding device 3 pass through the feed inlet 421.

[0033] When a portion of the bamboo strip 5 protrudes, the protruding portion of the bamboo strip 5 pushes the conveying structure II 34 and the outer shell 31 to move, thereby causing the corresponding limiting block 37 to move into the corresponding limiting groove 35 and compressing the elastic telescopic rod I 36.

[0034] The length of the rotating drum 41 is greater than the length of the bamboo strip 5. When a protruding bamboo strip 5 leaves the conveying structure II 34, the rotating drum 41 rotates, causing the protruding bamboo strip 5 to leave the feed port of the bamboo strip weaving machine and be discharged.

[0035] The working principle of this invention is as follows: When using this device, bamboo strip 5 is placed in the collection box 11, the transmission cylinder 14 rotates, and the uppermost bamboo strip 5 exposed outside the collection box 11 moves, so that the bamboo strip 5 moves between two opposing transmission structures I 33.

[0036] In normal condition, the bamboo strip 5 moves between conveyor structure I 33 and conveyor structure II 34, and eventually passes through the feed inlet 421 into the conveyor bucket 43 located on the inner wall of the rotating drum 41, and finally moves to the feed point of the bamboo strip weaving machine to participate in weaving.

[0037] When part of bamboo strip 5 protrudes (such as...) Figure 1 , 5 As shown), when the protruding part of the bamboo strip 5 passes the position of the conveying structure I33, it will push the corresponding central shaft I331, roller I332 and U-shaped frame I333 towards the inner wall of the outer shell 31 and compress the spring I336 until the protruding part of the bamboo strip 5 passes through the conveying structure I33. Then, under the elastic force of the spring I336, the roller I332 will return to its original position.

[0038] When the protruding position of bamboo strip 5 is at the position of conveying structure II 44, since the connecting rod II 344 is against the inner wall of the outer shell 31, the roller II 342 cannot move radially along the outer shell 31. Therefore, the protruding position of bamboo strip 5 pushes the conveying structure II 44 to move together in the direction of the screening device 4 until the connecting rod II 344 moves to the corresponding slot 22 position. Then the connecting rod II 344 moves into the slot 22, so that the protruding position of bamboo strip 5 can pass through the conveying structure II 44.

[0039] During the process of pushing the conveyor structure II44 to move at the protruding position of bamboo strip 5, since the connecting rod II344 is located in the perforation of the outer shell 31, the outer shell 31 also moves accordingly. The outer shell 31 drives the baffle 32 to move accordingly and compresses the elastic telescopic rod II24. At the same time, the outer shell 31 also drives the limiting block 37 to slide in the slide 441. When the connecting rod II344 is located inside the slot 22, the limiting block 37 moves to the other end of the slide 441.

[0040] When the limiting block 37 slides within the slide rail 441, after contacting the transmission rod 445, it pushes the transmission rod 445 to move, thereby driving the rotating rod 444 to rotate. The rotating rod 444 then drives the protrusion 446 to... Figure 13 Rotate clockwise in the indicated state to position the limiting block 37 at the connection between the slide rail 441 and the slide groove 442.

[0041] When the protruding part of bamboo strip 5 slides past the conveying structure II 34, under the elastic force of spring II 345, connecting rod II 344 disengages from slot 22. Since part of bamboo strip 5 is located inside the rotating drum 41 and the other part is located inside the outer shell 31, the rotating drum 41 cannot rotate relative to the outer shell 31 until all bamboo strip 5 disengages from the conveying structure II 34. Then, because the elastic telescopic rod II 24 is in a compressed state, the elastic telescopic rod II 24 drives the corresponding outer shell 31 to move back to its original position. Figure 13 As shown, the side of the protrusion 446 abuts against the locking block 413, restricting the rotation of the rotating rod 444 counterclockwise. Therefore, under the elastic force of the elastic telescopic rod II 24, the outer shell 31 is driven to move back to its original position. The limiting block 37 is interference-fitted with the limiting groove 35. Under the elastic force of the elastic telescopic rod I 36, it slowly moves away from the limiting groove 35. Before the limiting block 37 disengages from the limiting groove 35, the limiting block 37 pushes the transmission rod 445 to move and moves into the sliding groove 442, causing the limiting block 37 to slide along the sliding groove 442. Since the limiting cylinder 21 is fixed on the base plate 6, and the outer shell 31 is connected to the limiting cylinder 21 through the elastic telescopic rod II 24, the outer shell 31 cannot rotate relative to the limiting cylinder 21. Therefore, the limiting block... When the 37 moves into the chute 442, the rotating drum 41 rotates at least 90 degrees. (During the rotation of the rotating drum 41, the limiting block 37 on the stationary outer shell 31 is driven by the corresponding chute 441 to slide within the groove 38.) The rotating drum 41 drives the conveying drum 43 to rotate 90 degrees, making the bamboo strips 5 vertical. Since the feed inlet 421 is located at the eccentric position of the side plate 42, after it rotates 90 degrees, the feed inlet 421 deviates from the far conveying position, so that the protruding bamboo strips 5 cannot be aligned with the feed point of the bamboo strip weaving machine. As the conveying drum 43 rotates, the bamboo strips 5 are detached from the rotating drum 31 and discharged to the outside, preventing them from entering the bamboo strip weaving machine and thus avoiding their participation in weaving bamboo products and affecting the quality of the finished product. When the rotating drum 41 rotates due to the influence of the limiting block 37, the side plate 42 also rotates, causing the feed inlet 421 to rotate, thereby preventing subsequent bamboo strips 5 from entering the rotating drum 41 during the discharge process.

[0042] After the bamboo strip 5 is discharged from the rotating drum 41, under the elastic force of the elastic telescopic rod II 24, the limiting block 37 drives the limiting rod 443 to rotate around the spring hinge, so that the limiting block 37 moves back into the slide 441 and finally moves to the original position. At this time, the elastic telescopic rod I 36 pushes the limiting block 37 to the connection between the limiting groove 35 and the groove 38.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
