Description

Technical Field

[0001] The utility model relates to the technical field of wood processing equipment, in particular to a high-precision conveying and positioning mechanism for a plate of an edge banding machine. Background Art

[0002] Most of the boards used in the furniture manufacturing industry are compressed boards. In order to achieve exquisite beauty, the compressed boards need to be edge-sealed on all sides after the shape processing is completed to cover the internal structure of the compressed boards, and at the same time prevent the wood chips that make up the compressed boards from falling off after a long period of use, thereby extending the service life of the boards. In order to edge-band the boards, edge-banding machines came into being. Edge-banding of boards can not only slow down the release and have good environmental protection, but also prevent moisture from entering the board substrate to prevent deformation. At present, the boards of the board edge-banding machine are mainly transported by a conveyor belt driven by a chain driven by an ordinary motor fixed on the machine body. The boards are successively transported to the milling device and the pressing device for processing. The milling device and the pressing device have very high requirements for the positioning accuracy of the board transportation. Once a large error occurs in the transmission, it will seriously affect the quality of milling, pressing and polishing, and even cause the problem of scrapping the board. How to improve the positioning accuracy of board transportation has become a key research topic in the edge-banding machine manufacturing industry. Utility Model Content

[0003] The utility model provides a high-precision plate transmission and positioning mechanism for an edge banding machine, so as to solve the problem of large plate error in fixed common motor chain transmission in the prior art.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] The servo motor is fixed on the mounting plate, the linear slide rail is fixed on the rear part of the mounting plate, the output shaft of the servo motor is meshed with the transmission rack, the linear slide rail moves on the linear slide rail, the back plate adjustment mechanism is composed of upper and lower slide rails, upper and lower slide seats, lifting cylinders, front and rear slide rails, front and rear slide blocks, horizontal cylinders and front and rear pull plates of the back plate, the upper and lower slide rails are fixed on the mounting plate of the servo drive mechanism, the lifting cylinder piston rod is connected with the upper and lower slide seats, the upper and lower slide seats are lifted and lowered on the upper and lower slide rails, the lifting cylinder is connected with the mounting plate of the servo drive mechanism through the fixing plate, the front and rear slide rails and the horizontal cylinder are fixed on the top of the upper and lower slide seats, the front and rear slide blocks are installed on the bottom of the back plate and move on the front and rear slide rails, the piston rod of the horizontal cylinder is connected with the front and rear pull plates of the back plate, and the top of the front and rear pull plates of the back plate is connected to the back plate.

[0006] The piston rod of the lifting cylinder is connected with the upper and lower slide seats through a floating joint.

[0007] The working principle of the high-precision conveying and positioning mechanism of the edge banding machine of the utility model is as follows: in the initial state, the conveying and positioning mechanism is waiting at the origin on the board entry side of the edge banding machine, and the backing plate is in the rear side state below the plane of the board conveyor belt. After the processed board enters the board entry side of the edge banding machine and the board entry detection switch is activated, the execution signal will be transmitted to the conveying and positioning mechanism, and the backing plate will first move up to between the conveyor chain block surface and the pressure wheel surface and extend forward. The board will contact the backing plate during the movement, and the board and the backing plate will move forward, and the backing plate drives the linear slider to move on the linear slide rail, and the servo motor moves with it. At the same time, the encoder provided by the servo motor transmits displacement data to the electronic control system. After the processed board is processed by the milling device and the pressing device, the servo motor provides active power for the backing plate, driving the backing plate to move forward quickly. After the backing plate is separated from the board, the output shaft of the servo motor drives the transmission rack to enable the linear slider to move on the linear slide rail and reset to the origin on the board entry side, waiting for the next board to arrive for the next cycle.

[0008] The utility model adopts a transmission rack to replace the transmission chain with lower precision, and realizes the synchronous movement of the motor and the plate through the servo motor and the support plate, which effectively improves the plate transmission and positioning accuracy, ensures the processing quality of the edge banding machine milling device and the pressing device, and has the advantages of ingenious design, high transmission accuracy, high efficiency and stability.
