DETAILED DESCRIPTION

[0017] The specific implementation of the utility model will be further described in detail below with reference to the accompanying drawings.

[0018] The present invention provides a floating planing and flattening device for arc-shaped bamboo pieces, which is used for gradually shaping, yellowing and greening planing and step-by-step flattening of arc-shaped bamboo pieces. The curvature range of the arc-shaped bamboo pieces is usually 1 / 6π-3 / 5π (but not limited thereto). Figure 1 As shown, the floating planing and flattening device for curved bamboo strips includes a conveying and feeding mechanism 1 and a bamboo strip processing mechanism 2 which are electrically connected to a control system (not shown in the figure). A sensor assembly 130 is provided at the feeding end of the conveying and feeding mechanism 1. The sensor assembly 130 can detect the wall thickness of each curved bamboo strip in real time and transmit the wall thickness value to the control system in real time.

[0019] Further, the sensor assembly includes at least one CCD image sensor or thickness measuring instrument, such as Figure 4 As shown, multiple CCD image sensors are arranged horizontally and in parallel, which is conducive to efficient and accurate measurement of the thickness of the curved bamboo piece. Before the curved bamboo piece is planed and flattened, the operator inputs various control parameters into the control system, which can be an MES system, a PLC software system or an industrial computer.

[0020] Furthermore, the bamboo material feeding device is used for automatic feeding of arc-shaped bamboo pieces. The conveying and feeding mechanism 1 includes a loading platform 110, a cylinder push rod assembly 120 arranged at the feeding end of the loading platform 110, and a sensor assembly 130 for real-time thickness detection. The bamboo pieces to be fed are automatically fed into the bamboo material flattening device through the loading platform 110 under the action of the cylinder push rod assembly 120.

[0021] Furthermore, in order to improve the efficiency of bamboo material feeding, Figure 1 As shown, the loading platform 110 is provided with a first positioning assembly 111 for positioning the bamboo material. After loading, the telescopic rod 124 contracts under the action of the cylinder 123, and the next bamboo piece is continuously loaded, and this process is repeated, thereby realizing automatic loading of the bamboo tube. As can be seen from the above, in order to ensure that the last bamboo piece of the batch can also be smoothly delivered to the bamboo piece processing mechanism, the maximum length of the telescopic rod 124 in the extended state needs to be greater than the length of the conveyor belt.

[0022] The shaping mechanism, planing mechanism and flattening mechanism in the bamboo chip processing mechanism gradually shape, plan and flatten the arc-shaped bamboo chips in sequence. The mechanism gradually shapes, plan and flatten the arc-shaped bamboo chips in sequence. When the flattening device is working, the CCD image sensor transmits the thickness of the arc-shaped bamboo chips collected on the conveying and feeding mechanism to the control system in real time. The control system controls the servo motors of each mechanism to drive each functional roller to float up and down according to the thickness of the arc-shaped bamboo chips to adjust the spacing between each functional roller. It is suitable for shaping, planing and flattening of arc-shaped bamboo chips of different thicknesses, and the processing efficiency is significantly improved. The continuous floating planing and flattening device for arc-shaped bamboo chips provided by the present invention can remove part of the inner nodes of the bamboo and most of the bamboo partitions by "rolling" transportation, which is conducive to the smooth progress of subsequent planing processing.

[0023] After the bamboo chips are processed, they are transported to the bamboo chip shaping machine 3 through a crawler. A hot pressing platform 310 is installed on the top of the bamboo chip shaping machine 3. The top of the bamboo chip shaping machine 3 is fixedly connected to an outer frame 320, and a hydraulic press 330 is installed inside the outer frame 320. The bottom of the hydraulic press 330 is connected to a hot pressing plate 340. A limiting component 350 is arranged inside the outer frame 320, and the bottom of the bamboo chip shaping machine 3 is fixedly connected to a base 360.

[0024] The limiting assembly 350 includes a motor 351, a screw rod 352, a lifting block 353, a connecting block 354, a limiting block 355, a spring 356 and a damper 357. The motor 351 is installed inside the outer frame 320, and the output end of the motor 351 is detachably connected to the screw rod 352 through a coupling, and the outer surface of the screw rod 372 is threadedly connected to the lifting block 353, one side of the lifting block 353 is fixedly connected to the connecting block 354, and the limiting block 355 is arranged at the bottom of the connecting block 354, the top of the limiting block 355 is fixedly connected to the spring 356, and the inner wall of the spring 356 is sleeved with the damper 357.

[0025] Through the above technical solution, the lifting block 353 can be lifted and lowered by starting the motor 351, which then drives the limit block 355 at the bottom of the connecting block 354 to limit and fix the bamboo piece. In the process of limiting and fixing, the pressure can be relieved by the spring 355 and the damper 357 at the top of the limit block 355 to prevent the bamboo piece from being damaged due to excessive limiting pressure, thereby achieving the effect of limiting and fixing the bamboo piece and improving practicality.

[0026] Step S1, automatic feeding of arc-shaped bamboo pieces: the arc-shaped bamboo pieces are pushed into the flattening mechanism through the conveying and feeding mechanism electrically connected to the control system, and the thickness of the bamboo pieces is detected in real time through the sensor component; the control system controls the servo motors of each mechanism accordingly according to the thickness of the arc-shaped bamboo pieces transmitted in real time by the sensor component and drives each functional roller to float up and down, and adjusts the spacing between each functional roller; Step S2, shaping-planing-flattening of the arc-shaped bamboo pieces: the shaping mechanism, planing mechanism and flattening mechanism in the bamboo processing mechanism gradually shape, plan and flatten the charged arc-shaped bamboo pieces step by step in sequence,

[0027] Step S3, flattening the bamboo pieces and shaping them: the flattened bamboo pieces are pushed onto the crawler by a pusher and sent into a bamboo piece shaping machine for hot pressing and shaping.
