Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0045] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0046] The present invention discloses a double-disc saw cutting system, which is capable of automatically cutting boards of specific lengths and different widths into short boards of various specifications required by customers, so as to improve efficiency and adapt to production requirements by adopting a double-disc saw cutting scheme. Generally, the production speed of a continuous composite board production line should reach 5-10 meters per minute, and its own band saw machine cannot complete the cutting of short boards below 2.4 meters under such production intensity, otherwise the production efficiency will be reduced to a very low level, and the requirements for the entire conveying system of the production line will also be increased, and the cost of the conveying system will naturally increase.

[0047] The system comprises a conveying device 10, a positioning and edging mechanism, a pressing device 7, a cutting device, a fixed-length baffle device 6, a board entry inspection device, a length measuring device, and a board lowering device.

[0048] The plate first enters the preparation station of the conveying device 10, and then enters the edge station. When the edge feeding detection device (using the existing optical sensor) detects the plate head, the conveying device 10 stops at the edge station; the positioning edge mechanism pushes the plate to the edge to prepare for cutting. When the edge detection device detects that the plate is close to the edge, in order to ensure that the plate is completely close to the edge, the edge detection device is composed of two sets of sensors (using the existing optical sensors) at the front and back, and after the two sets of sensors send signals at the same time, the controller will also delay the stop of the action of the positioning edge mechanism; then the conveying device 10 starts to move the plate The plate is sent to the fixed-length station, and the positioning cylinder on the fixed-length baffle device 6 is triggered, and the positioning side mechanism on the fixed-length station is activated to clamp the plate. The positioning side mechanism has a guide wheel on the side structure. At this time, the plate can move back and forth, and the plate clamps the positioning cylinder on the fixed-length baffle device 6 to push the plate so that the plate is accurately positioned in the length direction. Then the pressing plate device 7 on the cutting station is activated to press the plate, and then the cutting device on the cutting station is activated to cut the plate according to the required length (specifically, there are two cutting machines on the cutting device, one is fixed and one is moving, and the moving end cutting machine 1 is controlled by the servo system). The horizontal transmission system of the cutting machine is controlled to perform accurate repeated positioning, and the moving end cutting machine 1 is accurately adjusted to ensure the cutting accuracy of plates of different lengths. The moving end requires the servo motor to control the moving end cutting machine 1 to reach the specified position according to the product length requirements. At the same time, in order to prevent the moving end cutting machine 1 from cutting the roller on the conveying device 10 after changing its position, the conveying device 10 at the moving end cutting position is provided with a roller moving device 8. If the servo system controls the moving end cutting machine 1 to move near the roller on the conveying device 10, the feedback signal causes the roller moving device 8 to move to prevent the roller from being cut; when the plate After it is in place, the pressure plate device 7 completes the clamping, the cutting machine descends, and after the lower limit proximity switch 13 senses in place, the cutting component stops descending, the cutting machine is turned on, and the transverse device is started. The transverse transmission belt 44 drives the cutting components with two cutting machines to cut horizontally under the action of the transverse main transmission wheel assembly, and cuts the plate according to the plate width information fed back by the length measuring device, and stops immediately to improve efficiency. At this time, the cutting machine rises, and stops rising after the upper limit proximity switch 12 senses in place. The moving end and fixed end cutting machines have independent lifting control devices 11, and the cutting components return to the origin according to the origin limit on the transverse device).

[0049] After the plate processing is completed, the positioning cylinder on the fixed-length baffle device 6 is released, the positioning edge mechanism on the fixed-length station is released, and then the fixed-length baffle device 6 and the pressure plate device 7 are lifted, so that the conveying device 10 can deliver the plate into the lower plate station.

[0050] After entering the unloading station, the sensor reaches the predetermined position, and then the robot moves to unload and stack the finished panels.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
