[0002] Bamboo fiber is cellulose fiber extracted from naturally grown bamboo. Its main substance is cellulose, and it is a natural, environmentally friendly green fiber.

[0003] In the bamboo fiber manufacturing process, the bamboo needs to be segmented and broken to form bamboo strips, which are then placed in a box and then placed in a laying station for laying. The existing practice is to lay the strips manually, which has low efficiency and may form sharp edges on the edges of the bamboo strips after segmentation and breaking, thus causing injuries to the workers.

[0004] The inventor studied the bamboo chips after breaking and found that after breaking, the bamboo chips are stacked in a box and placed in layers. Therefore, after long-term research, the inventor proposed a chip feeding mechanism (publication number: CN219135406U). However, during use, it was found that the bamboo chip unloading effect was not good. During the unloading process, the clamping force on the bamboo chips was insufficient, which led to low unloading efficiency, poor unloading effect, and inconvenient transportation of the box.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a material unloading and paving feeding device includes a frame 2, a lifting device 3, a plate conveyor 1 and a chain conveyor 7 for conveying a box 8 filled with bamboo chips to the bottom of the plate conveyor 1. In this embodiment, the frame 2 spans the chain conveyor 7. The frame 2 includes four supporting legs and a rectangular frame. The four supporting legs are respectively located on the four corners of the rectangular frame. A plate conveyor 1 is installed on the top of the frame 2. The plate conveyor 1 is a prior art, and its specific structure is not repeated here. The plate conveyor 1 has a chain plate, and a scraper 5 is installed on part of the chain plate of the plate conveyor 1. Further, the scraper 5 is an L-shaped plate, which is arranged at intervals in the conveying direction of the plate conveyor 1, such as Figure 4 As shown, the connecting end of the scraper 5 is welded to the scraper 5 on the corresponding chain plate, and a serrated groove 51 is provided at the end away from the chain plate. There are multiple serrated grooves 51, and adjacent serrated grooves 51 are connected, so the scraping end of the scraper 5 forms a serrated structure. When the serrations come into contact with the bamboo pieces, the serrations can press the bamboo pieces, and with the rotation of the plate conveying device 1, the bamboo pieces are driven to move, thereby realizing the unloading of the bamboo pieces, and when unloading, the serrations only act on the bamboo pieces on the top layer, so it can only drive the bamboo pieces on the top layer to leave the lifting device 3, so that the bamboo pieces can be laid on the paving station after unloading, thereby making the paving of the bamboo pieces at the paving station simple, and realizing the paving feeding of the paving station.

[0028] In the present embodiment, the chain conveyor 7 is a prior art, and its specific structure is not described in detail. There is a gap between the two chains of the chain conveyor, and the box 8 is placed across the chain conveyor. The box 8 is filled with bamboo pieces, and its own weight is heavy, so it can move well with the chain conveyor. When the chain conveyor is working, the box 8 is transported to the bottom of the plate conveyor 1. In the present embodiment, the box 8 is a rectangular box 8, the top of which is an open mouth, and the side panels around the box 8 form a rectangular structure, with inwardly bent flanges at the bottom of the side panels, and the bottom plate of the box 8 is placed on the flanges. When the bottom plate is lifted by the lifting device, the bottom plate can move relative to the box 8.

[0029] In this embodiment, if Figure 1 , Figure 2As shown, the execution end of the lifting device matches the inner cavity of the box 8, the lifting device 3 is located in the frame 2, and the lifting device 3 is located below the plate conveying device 1. Preferably, the lifting device 3 is a scissor-type lift, which is a prior art. Its top layer has a bearing platform 31, so it can stack the bamboo pieces of each other. At the same time, the bottom of the scissor-type lift is a base 32, and the bearing platform 31 and the base 32 are both rectangular structures. The bearing platform 31 matches the inner cavity of the box 8. In this embodiment, the bamboo pieces are stacked and placed in the box 8, the bottom of the box 8 is an open mouth, and the size of the bearing platform 31 matches the inner cavity of the box 8. When the bearing platform 31 rises, the bottom plate of the box 8 and the bamboo pieces in the box 8 are driven to rise, while the side plates of the box 8 do not move, so that the bamboo pieces can emerge from the top of the box 8, so that the bamboo pieces are convenient to contact with the scraper 5 and finally scraped away by the bamboo pieces. In this embodiment, rollers can be set on the base 32 to facilitate the movement of the scissor-type lift.

[0030] In this embodiment, if Figure 2 and Figure 3 As shown, four height adjustment devices 4 distributed in a matrix are installed on the frame 2, and the lifting end of the height adjustment device 4 is connected to the conveying frame of the plate conveying device 1. The horizontal height of the plate conveying device 1 can be fine-tuned through the height adjustment device 4. Furthermore, the height adjustment device 4 includes a hydraulic cylinder 41, and beams 42 are installed in pairs on the top of the frame 2. A mounting plate 43 is installed between two corresponding beams 42. The hydraulic cylinder 41 is installed on the mounting plate 43, and the piston rod of the hydraulic cylinder 41 is connected to the conveying frame. By controlling the hydraulic cylinder 41, the piston rod is extended and retracted, so that the conveying frame can be controlled to be lifted and lowered, thereby realizing the height adjustment of the plate conveying device 1.

[0031] In this embodiment, if Figure 3 As shown, a support frame 46 extending outward is installed on the conveying frame, and the piston rod of the hydraulic cylinder 41 is connected to the support frame 46, so as to facilitate the connection between the piston rod and the support frame 46. Optionally, a step is provided on the piston rod, and an external thread is provided on the piston rod below the step, and a through hole is provided on the support frame 46, so that the piston rod passes through the support frame 46, and then a locking nut is sleeved on the piston rod, and then the locking nut is locked.

[0032] In this embodiment, if Figure 3 As shown, a linear bearing 45 is also installed on the mounting plate 43, and a guide shaft 44 is vertically installed on the support frame 46. The guide shaft 44 slides in the linear bearing 45. Through the cooperation between the guide shaft 44 and the linear bearing 45, the straightness of the vertical movement of the plate conveyor 1 can be guaranteed, thereby ensuring the horizontality of the plate conveyor 1 during the adjustment process.

[0033] In this embodiment, if Figure 1and Figure 2 As shown, the front of the lifting device 3 also includes a material blocking device 6, which includes a baffle 61 and a lifting cylinder 62. The piston rod of the lifting cylinder 62 is connected to the bottom of the baffle 61, and the material blocking device 6 is located in the gap between the two chains. When the chain conveyor 7 transports the box 8 to the bottom of the plate conveyor, the lifting cylinder 62 works, and its piston rod is pushed out, thereby causing the baffle 62 to rise. In the vertical direction, the baffle 62 passes over the chain conveyor 7. When the box 8 contacts the baffle 62, the baffle 62 blocks the box 8. At the same time, the chain conveyor 7 stops working, and then the lifting cylinder 62 stops working and resets, thereby causing the baffle 62. At this time, in the vertical direction, the baffle 62 is located below the bottom of the box 8, and the initial position of the supporting platform 31 is also located below the box 8.

[0034] The working process of the utility model is as follows: the box 8 with bamboo chips is placed on the chain conveyor 7, the chain conveyor 7 works to convey the box 8 to the bottom of the plate conveyor 1, and the blocking mechanism is used to limit the position of the box 8, so that the position of the box 8 just corresponds to the lifting device 3 and the plate conveyor 1, and then the lifting device 3 works, the carrying platform 31 of the lifting device 3 rises, so that the bamboo chips gradually approach the plate conveyor 1, and when the bamboo chips contact the scraper 5, the plate conveyor 1 works, so that the scraper 5 moves, and due to the serrated structure of the scraper 5 and the structure of the bamboo chips, after the scraper 5 moves, it can drive the bamboo chips on the uppermost layer to move, and then drive the bamboo chips into the paving process. When the unloading of the bamboo chips on the uppermost layer is completed, the lifting device 3 rises a certain distance again, so that the bamboo chips on the upper layer contact with the scraper 5, and the above actions are repeated to realize the unloading of the bamboo chips. If it is found that the bamboo chips cannot be taken away by the scraper 5, it means that the clamping force between the scraper 5 and the bamboo chips is insufficient. At this time, the lifting device 3 can be controlled to rise so that the scraper 5 can press the bamboo chips. Of course, the height of the plate conveyor 1 can also be fine-tuned to make the scraper 5 move downward, and then the scraper 5 presses the bamboo chips. When the unloading of the bamboo chips is completed, the lifting device 3 is reset, and then the chain conveyor transports the empty box 8 out of the frame, and at the same time transports the next box 8 to the bottom of the plate conveyor.
