Technical Field

[0001] This utility model relates to the technical field of bamboo and wood processing equipment, specifically to a press side-pressure feeding mechanism. Background Technology

[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 upright (side-pressing process), the multiple stacked bamboo strips are tall and narrow, making them prone to tipping over during the laying process, leading to installation failure; 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 the side-pressing laying mode. Utility Model Content

The side pressure plate feeding mechanism consists of two sets of side pressure plates that are alternately side-pressing the two sets of strip-shaped openings. Each set of side pressure plate feeding mechanism includes two side pressure plate feeders respectively set in each strip-shaped opening. The side pressure plate feeder includes a magnetically coupled telescopic cylinder that passes through the strip-shaped opening in a horizontal direction. The magnetically coupled telescopic cylinder is provided with a lifting telescopic cylinder located in the strip-shaped opening. The telescopic rod of the lifting telescopic cylinder is set upward and connected to a feeding column that can pass upward through the strip-shaped opening under the drive of the lifting telescopic cylinder to side-press a row of side-standing bamboo strips from the side of the outermost bamboo strip.

[0008] Preferably, the movable pressure roller mechanism includes a mounting frame straddling the frame and located at the end of the feeding conveying direction of the material spreading platform.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] A press side-pressure 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 a reference platform for laying bamboo strips and feeding them. A side-pressing plate feeding mechanism 3 is installed on the spreading platform 1, which alternately presses the bamboo strips to secure them and prevent them from tipping over. A movable side-blocking mechanism 2 is installed on one side of the frame 7 in the feeding direction of the spreading platform 1, which laterally compresses the bamboo strips to a set feeding width after laying. A set of movable pressing roller mechanisms 4 are positioned opposite each other at both ends of the frame 7 in the feeding direction of the spreading platform 1. These movable pressing roller mechanisms 4 are located above the spreading platform 1 and can be opened and closed, pressing down the bamboo strips laid on the spreading platform 1. A feeding mechanism 5 is also installed on the spreading platform 1, which pushes the laid bamboo strips into the press.

[0020] like Figure 4 As 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.

[0021] The material spreading platform 1 has two sets of horizontally spaced strip-shaped openings. Each set includes two parallel strip-shaped openings 12, perpendicular to the material feeding direction. The side-pressure plate feeding mechanism 3 consists of two alternating sets, each corresponding to one of the two sets of strip-shaped openings. Each set includes two side-pressure plate feeders, one for each strip-shaped opening 12. Figure 5 As shown, the side-pressing plate feeder includes a magnetically coupled telescopic cylinder 31 that extends horizontally through a strip-shaped opening 12. A lifting telescopic cylinder 32 is mounted on the magnetically coupled telescopic cylinder 31 within the strip-shaped opening 12. The telescopic rod of the lifting telescopic cylinder 32 is upward-facing and connected to a feeding column 33. Driven by the lifting telescopic cylinder 32, the feeding column 33 extends upward through the strip-shaped opening 12, thereby pressing down on a row of side-standing bamboo strips from the outermost side. Specifically, in use, the lifting telescopic cylinder 32 drives the feeding column 33 to rise and fall, while the magnetically coupled telescopic cylinder 31 drives the lifting telescopic cylinder 32 to move horizontally to a designated position, so that the feeding column 33 presses down on or releases the bamboo strips.

[0022] 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.

[0023] like Figure 6 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.

[0024] 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.

[0025] The working principle of this utility model is as follows: 1. Initial state: The material spreading platform 1 is emptied, the feeding pusher 55 is moved away from the discharge end near the press, and the movable pressing roller mechanism 4 is deployed; the state of the bamboo strips after gluing is as follows. Figure 7 As shown on the left, adhesive is applied between adjacent bamboo strips. After the robotic arm picks up the bamboo strips, it rotates them 90 degrees. Figure 7 As shown on the right.

[0026] 2. The robotic arm lays the bamboo strips on the laying platform 1, at which point the laying platform 1 has a row of bamboo strips standing upright.

[0027] 3. Since the bamboo strips cannot be laid out at once, a set of side pressure plate feeding mechanisms 3 is used to press down the bamboo strips to prevent them from tipping over. After pressing down the bamboo strips, they cannot be released immediately. Therefore, the next bamboo strip to be grabbed is pressed down by another set of side pressure plate feeding mechanisms 3. The two sets of side pressure plate feeding mechanisms 3 alternately complete the pressing action.

[0028] 4. Since the bamboo strips laid by the robotic arm will be larger than the feeding width, the movable edge guard mechanism 2 will compress the bamboo strips to the feeding width after the laying is completed.

[0029] 5. After compression, the movable pressing roller mechanism 4 drops down to hold the bamboo strip in place, and the feeding push plate 55 of the feeding mechanism 5 pushes the entire strip into the press. After completion, all mechanisms reset.
