[0002] In the production of bamboo-based composite materials (such as bamboo cutting boards and bamboo flooring), glued bamboo strips need to be neatly laid out and fed into a hot press for pressing and shaping. Traditional material feeding methods rely heavily on manual labor or semi-automatic equipment, which has the following drawbacks: 1) When bamboo strips need to be laid flat (flat pressing process), multiple layers of side-coated bamboo strips are prone to stacking and misalignment in the material cavity, affecting the quality of the finished product; 2) The entire feeding process is inefficient and labor-intensive, making it difficult to meet the needs of modern continuous production. Therefore, there is an urgent need for a specialized device that can automatically and stably complete the bamboo strip laying and feeding in flat pressing mode. Utility Model Content

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] A press flat-press feeding mechanism, combined with Figures 1 to 3 As shown, the machine includes a frame 7, on which a spreading platform 1 is horizontally mounted. The spreading platform 1 serves as the reference platform for laying bamboo strips and feeding them. A single-board feeding mechanism 6 is located on one side of the frame 7, opposite to the feeding direction of the spreading platform 1. This mechanism receives, flattens, and pushes bamboo strips onto the spreading platform 1 piece by piece. A movable edge-blocking mechanism 2 is located on the side of the spreading platform 1 opposite to the single-board feeding mechanism 6. This mechanism laterally compresses the bamboo strips to a set feeding width after laying. A set of movable pressure roller mechanisms 4 are located opposite each other at both ends of the frame 7, opposite to the feeding direction of the spreading platform 1. These mechanisms are located above the spreading platform 1 and can be opened and closed. The movable pressure rollers 4 press down the bamboo strips laid on the spreading platform 1. A feeding mechanism 5 is also provided on the spreading platform 1, which pushes the laid bamboo strips into the press.

[0023] like Figure 4As shown, a groove 11 is provided on the spreading platform 1 at a position corresponding to the movable edge-blocking mechanism 2. The movable edge-blocking mechanism 2 includes a movable edge-blocking telescopic cylinder 21 located at the bottom of the spreading platform 1. The telescopic rod of the movable edge-blocking telescopic cylinder 21 passes through the groove 11 and is connected to a movable edge-blocking push plate 22. The movable edge-blocking push plate 22 is erected in the groove 11, and the bottom of the movable edge-blocking push plate 22 is slidably assembled with the groove 11. The top of the movable edge-blocking push plate 22 is higher than the upper surface of the spreading platform 1. When it is necessary to compress the width of the bamboo strips laid on the spreading platform 1, the movable edge-blocking telescopic cylinder 21 pushes the movable edge-blocking push plate 22 to move within the groove 11, pushing the bamboo strips laterally to the specified width.

[0024] The movable pressure roller mechanism 4 includes a mounting frame 41 spanning the frame 7 and located at the end of the feeding conveying direction of the material spreading platform 1. A frame shaft 42 is rotatably mounted on the mounting frame 41, and the frame shaft 42 is horizontally arranged along the spanning direction of the mounting frame 41. A frame 43 is connected to the frame shaft 42, and several pressure rollers 44 are movably mounted on the frame 43 through spring pressure supports 47, spaced apart along the feeding conveying direction. The pressure rollers 44 are used to provide downward pressure. A tilting drive telescopic cylinder 46 is hinged to the frame 7, and a hinge plate 45 is hinged to the telescopic rod end of the tilting drive telescopic cylinder 46. The other end of the hinge plate 45 is fixedly connected to one end of the frame shaft 42. When the pressure roller 44 needs to provide downward pressure, the telescopic rod of the tilting drive telescopic cylinder 46 on the frame 7 retracts, thereby driving the hinge plate 45 to rotate. The rotation of the hinge plate 45 drives the frame shaft 42 to rotate, and the frame shaft 42 actively drives the frame 43 to rotate downward, thereby pressing down the entire frame together with the pressure roller 44. When pressing down, the spring pressure support 47 provides elastic clamping force. When the pressure roller 44 needs to be lifted, the telescopic rod of the tilting drive telescopic cylinder 46 extends, driving the frame shaft 42 to rotate in the opposite direction.

[0025] like Figure 5 As shown, clearance openings 431 are respectively provided on the mounting frame 41 at positions opposite to the two ends of the pressure roller 44. The spring pressure support 47 includes a fixed cover 471 disposed on the mounting frame 41, which covers the clearance opening 431 from the outside. A movable body 472 is slidably mounted in the fixed cover 471, and the end of each pressure roller 44 is rotatably connected to the corresponding movable body 472. A guide pin 473 is fixedly connected to the movable body 472, and the other end of the guide pin 473 extends out of the fixed cover 471 and is slidably mounted with the fixed cover 471. A spring 474 is sleeved on the guide pin 473 between the fixed cover 471 and the movable body 472. When the movable pressure roller mechanism 4 is pressed down, the spring 474 provides an elastic clamping force.

[0026] like Figure 6As shown, the single-board feeding mechanism 6 includes a fixed side baffle 61, an offset side baffle 64, and a support plate 65. The fixed side baffle 61 is fixedly mounted on the frame 7 and located to the side of the spreading platform 1. There are two offset side baffles 64 spaced apart along the feeding direction. The two offset side baffles 64 are located on the outside of the fixed side baffle 61 away from the movable pressure roller mechanism 4 and are parallel to the fixed side baffle 61. The two offset side baffles 64 can move away from and close to the fixed side baffle 61. The support plate 65 is fixedly mounted on the frame 7 and located below the fixed side baffle 61 and the offset side baffle 64. The support plate 65 abuts against the spreading platform 1, and the upper surface of the support plate 65 is flush with the upper surface of the spreading platform 1.

[0027] A number of first vertical baffles 611 are spaced apart along the feeding direction on the side of the fixed side baffle 61 facing the offset side baffle 64, and the first vertical baffles 611 are arranged longitudinally. A number of second vertical baffles 641 are arranged on the side of the offset side baffle 64 facing the fixed side baffle 61, and the second vertical baffles 641 are arranged opposite to each of the first vertical baffles 611. A material cavity 66 is formed between the second vertical baffles 641, the first vertical baffles 611 and the support plate 65. The material cavity 66 is used to accommodate a stack of horizontally stacked bamboo strips with glue on the sides, and the distance between the bottom end of the first vertical baffle 611 and the support plate 65 is greater than the thickness of one bamboo strip and less than the thickness of two bamboo strips. The offset side baffle 64 is also provided with several pressing components 67 and single-board feeding components 68 at intervals along the feeding and conveying direction. The pressing components 67 are used to press down the bamboo strips from the top of the bamboo strips in the material cavity 66; the single-board feeding components 68 are used to push the bamboo strips from the bottom of the bamboo strips in the material cavity 66 onto the spreading table 1 one by one.

[0028] The frame 7 is provided with two inclined supports 62, which are located on the outer sides of the fixed side baffle 61 and inclined upwards outwards from the fixed side baffle 61. A triangular sliding frame 63 is slidably mounted on the inclined surface of each inclined support 62, and two offset side baffles 64 are respectively mounted on the two triangular sliding frames 63.

[0029] like Figure 7As shown, a rack 631 is also provided on the surface of the triangular sliding frame 63 that is slidably assembled with the inclined support 62. An offset side stop shaft 621 is rotatably connected between the two inclined supports 62. The offset side stop shaft 621 is horizontally positioned, and gears 622 are respectively provided at both ends of the offset side stop shaft 621. The gears 622 mesh with the rack 631 on the same side. The offset side stop shaft 621 is also connected to a sliding drive motor 623, which is mounted on the frame 7. The sliding drive motor 623 drives the offset side stop shaft 621 to rotate. The rotation of the offset side stop shaft 621 drives the gears 622 to rotate, which in turn drives the rack 631 to move. The movement of the rack 631 causes the triangular sliding frame 63 to slide, thus enabling the triangular sliding frame 63 to move along the inclined surface of the inclined support 62. This allows the offset side stop 64 to move away from and closer to the fixed side stop 61 from the outside and above.

[0030] like Figure 8 As shown, the pressing assembly 67 includes a pressing telescopic cylinder 671 mounted on the offset side baffle 64. The telescopic rod of the pressing telescopic cylinder 671 is set upward and connected to a mounting plate 672. The mounting plate 672 is connected to a pressing plate 674 and a guide rod 673 set vertically downward. The pressing plate 674 is L-shaped. A guide opening 642 is longitudinally opened on the second vertical baffle 641. The guide opening 642 is used to pass through the horizontal body of the pressing plate 674, thereby avoiding the pressing plate 674 and realizing the pressing guide of the pressing plate 674. The pressing assembly 67 drives the pressing plate 674 to press down along the guide opening 642 through the pressing telescopic cylinder 671. The horizontal body of the pressing plate 674 presses down on the bamboo strip from the top of the bamboo strip in the material cavity 66. The guide rod 673 is slidably assembled with the offset side baffle 64. The guide rod 673 is used to realize the lifting and lowering guide of the mounting plate 672 driven by the pressing telescopic cylinder 671.

[0031] The single-board feeding assembly 68 includes a single-board feeding telescopic cylinder 681 mounted on the pallet 65. The telescopic rod of the single-board feeding telescopic cylinder 681 is positioned towards the material cavity 66 and connected to a single-board feeding push plate 682. The single-board feeding assembly 68 drives the single-board feeding push plate 682 through the single-board feeding telescopic cylinder 681 to push the bottom layer of single bamboo strips in the material cavity 66 onto the spreading platform 1 in sequence.

[0032] The feeding mechanism 5 includes an active feeding shaft 51 and a driven feeding shaft 52, which are respectively located at both ends of the feeding conveying direction of the spreading platform 1. A sprocket 53 is connected to each end of the active feeding shaft 51 and the driven feeding shaft 52, and a chain 54 meshes between the two sprockets 53 on the same side of the active feeding shaft 51 and the driven feeding shaft 52. A feeding push plate 55 is arranged between the two chains 54, and the feeding push plate 55 spans across the spreading platform 1, its height ensuring that it can push the bamboo strips laid on the spreading platform 1. The active feed shaft 51 is connected to a feed drive motor 56 via a transmission assembly (the transmission assembly is existing technology and can be a belt and pulley transmission assembly, sprocket and chain transmission assembly, etc., which are not limited or described in detail here). The feed drive motor 56 is mounted on the frame 7 and drives the active feed shaft 51 to rotate. The rotation of the active feed shaft 51 drives the sprocket 53 to rotate, and the rotation of the sprocket 53 drives the chain 54 to rotate. The rotation of the chain 54 realizes the pushing action and resetting of the feed pusher plate 55.

[0033] The working principle of this utility model is as follows: 1. Initial state: The spreading table 1 is emptied, the feeding pusher 55 is moved away from the discharge end near the press, the movable pressing roller mechanism 4 falls down, forming a limited space of a certain thickness between itself and the plane of the spreading table 1; the pressing telescopic cylinder 671 of the pressing assembly 67 extends, causing the pressing plate 674 to rise, and the offset side baffle 64 rises away from the fixed side baffle 61, thereby preventing the bottom of the pressing plate 674 from obstructing the feeding; the state of the bamboo strips after gluing is as follows. Figure 9 As shown on the left, the upper surface of a row of bamboo strips standing on their sides is coated with adhesive. A robotic arm grabs the bamboo strips from the trough and rotates them 90 degrees, as shown... Figure 9 As shown on the right.

[0034] 2. The robotic arm places the bamboo strip into the material cavity 66 and approaches the first vertical baffle 611. The deflectable side baffle 64 falls down, the material cavity 66 shrinks, and the second vertical baffle 641 blocks the material from the other side of the bamboo strip. The robotic arm withdraws, and the downward pressing telescopic cylinder 671 of the pressing assembly 67 retracts, causing the pressing plate 674 to descend and press the bamboo strip from the top, flattening the bamboo strip.

[0035] 3. The single-board feeding assembly 68 operates, pushing the bamboo strips horizontally into the defined space on the spreading table 1 one by one. This process is repeated. After a set of bamboo strips is pushed out, the robotic arm continues to feed, and the single-board feeding assembly 68 continues to operate until the defined space is filled.

[0036] 4. After the bamboo strips are fully laid, the movable edge guard mechanism 2 is activated to compress the bamboo strips to the feeding width.

[0037] 5. After compression, the entire assembly is pushed into the press by the feed pusher plate 55 of the feeding mechanism 5. After completion, all mechanisms are reset.
