Detailed Description

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings for clarity and understanding of technical contents. The present invention may be embodied in many different forms of embodiments and the scope of the invention is not limited to the embodiments set forth herein.

In the drawings, structurally identical elements are represented by like reference numerals, and structurally or functionally similar elements are represented by like reference numerals throughout the several views. The size and thickness of each component shown in the drawings are arbitrarily illustrated, and the present invention is not limited to the size and thickness of each component. The thickness of the components may be exaggerated where appropriate in the figures to improve clarity.

As shown in fig. 1, an embodiment of the present invention provides an auxiliary device for flat-pressing and splicing bamboo strips, the auxiliary device is installed between a pressing plate 2 and a pressing roller 9, and the auxiliary device includes: the device comprises a motor 3, a belt pulley transmission mechanism 6, a nylon brush hair roller 7 and a hydraulic swing arm; the nylon brush hair roller 7 is driven by the belt pulley transmission mechanism 6; the hydraulic swing arm comprises a hydraulic device 4 and a link mechanism 5; the motor 3 is a horizontal low-rotating-speed alternating-current micro motor, is arranged on a support, is driven by a belt pulley driving mechanism 6, and gives enough friction force to a nylon brush hair roller 7 by a link mechanism 5 with the height controlled by a hydraulic device 4. The link mechanism 5 is made of Al5052 and is subjected to hard anodizing treatment, and the bearing is a high-quality SKF roller bearing 206. The belt pulley transmission mechanism 6 is provided with a transmission wheel, a roller shaft and a transmission belt. The transmission wheel is made of Al6061 and is subjected to hard anodic oxidation treatment, and the transmission belt is made of a rubber belt with glass fibers matched inside as wire cores. The small horizontal motor is selected, and a 1HPx4P-28E type motor is selected according to actual working conditions. The nylon brush hair roller 7 comprises a roller and nylon point claws, and the nylon point claws are spirally distributed outside the roller; the gyro wheel is at rotatory in-process, and the frictional force of equipartition is done on the bamboo timber surface for bamboo clapper flushes in push pedal department when piecing together wide, and bamboo clapper piece joint department connects inseparabler during the concatenation. A spring leaf is arranged between the roller and the roller shaft. During pressing production, the hydraulic device 4 applies downward pressure to the link mechanism 5 and the nylon bristle roller 7, and stops applying pressure when the nylon bristle roller 7 reaches a certain height. The nylon brush hair roller 7 and the push plate 10 at the front end of the hot press start to operate simultaneously, the roller rotates outwards along the axial direction, the nylon point claw on the roller gives a force to the bamboo strip 8, the force is opposite to that of the push plate 10, the bamboo strip 8 is aligned with the end of the push plate 10 before entering the press plate 2, and the extension part is tightly connected. A spring piece is arranged between the roller and the roller shaft, so that the nylon point claw can be pushed to adapt to the thickness change of the bamboo chips at any time, and the pushing force cannot be exerted due to the thin thickness of the bamboo strips.

As shown in fig. 1 to 2, a worker places bamboo battens 8 on a bottom plate 11, a sensor is mounted on a compression roller 9 and adopts an infrared single-chip microcomputer signal transmission mode, safety and transmission stability are both considered, the sensor has a counting function, and when detecting the bamboo battens 8, the sensor transmits working signals to a motor 3 and a hydraulic device 4. After the motor 3 and the hydraulic device 4 receive signals, the work is started successively. When the motor 3 reaches a constant rotating speed, the nylon brush hair roller 7 at the tail end of the hydraulic device 4 works to a working height h from a zero position, and the pressure is stabilized. When the push plate 10 makes the bamboo splints 8 pass through the press plate 2 and completely pass through the baffle plate 1, the nylon brush hair roller 7 is reset to a zero position from the working height h, and meanwhile, the motor 3 stops working. In fig. 2, x is the distance between the center of the turntable and the bottom of the point claw, and h is the distance between the center of the turntable and the bamboo strip. When x is less than 1.08h, the point claws are far away from the bamboo strips, and the generated friction force is not enough to drive the bamboo strips. When the time is more than 1.12h, the generated friction force is too large, and the roller cannot normally operate. Therefore, x is controlled to be between 1.08h and 1.12 h. The roller structure with the spring piece and the nylon point claw at the upper end and the lower end is fixed at the top end of the hydraulic swing arm in a pinned mode, and the nylon point claw does not idle or clamp on the surface of a bamboo batten through local simple harmonic motion when passing through the bamboo battens with different thicknesses, namely the strict requirement on the proportional relation between x and h is reduced due to the application of the spring piece.

As shown in fig. 3, the hydraulic system uses a hydraulic pump 17 to supply hydraulic oil, uses a directional valve 14 to use a three-position four-way valve, and controls the stroke of the hydraulic cylinder 13 to control the motion of the hydraulic swing arm. After receiving the working signal of the sensor mounted on the compression roller 9, the hydraulic pump 17 starts to work, and the reversing valve 14 is in the middle position, and the hydraulic oil returns to the oil tank 16 through the overflow valve 15. When the motor 3 reaches the working speed, the reversing valve 14 is changed to the right position, and the link mechanism 5 is pressed down to the working height h (as shown in fig. 2). When the bamboo board 8 passes through the pressing board 2 and the baffle 1 completely by the pushing board, the reversing valve 14 is changed into a left position, and the link mechanism 5 is lifted to a zero position. After the hydraulic cylinder 13 reaches the zero position, the reversing valve 14 is switched to the neutral position, the hydraulic oil returns to the oil tank 16 through the overflow valve 15, and finally the hydraulic pump 17 stops working.

The hydraulic pump 17 adopts the working pressure of 0-22MPa, the motor power of 2.2KW and the electromagnetic valve voltage DC12V, which is the working oil pressure suitable for the three-position four-way reversing valve 14 and can meet the actual working condition. The change-over valve 14 is a common 34D-10B type three-position four-way electromagnetic change-over valve.

According to the auxiliary device for bamboo batten flat pressing splicing, when the bamboo battens are subjected to flat pressing, width splicing and lengthening, one end of each bamboo batten can be kept flush before entering the pressing plate device, and the joint of the lengthened joint is close to splice without gaps. The auxiliary device can replace the existing positioning compression roller by using a roller shaft with a roller, the periphery of the roller adopts a point claw type structure, a plurality of contacts are distributed on the roller, and each bamboo strip is at least provided with one contact for contact driving. The point claw part is made of a material with a high friction coefficient and does not damage the surface of the bamboo material. And the roller shaft can be lifted and lowered according to the operation requirement through the hydraulic cylinder.

The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts.
