Design of automatic plywood trimming machine

In the field of plywood production, it is a fully automatic edge cutting machine for plywood, which is one of the necessary equipment for plywood production. After the plywood is processed and formed, the edge cutting machine needs to be used to cut the edges, so that the size of the plywood is consistent and the surplus parts are scattered.

It includes two first motors arranged horizontally, one side of the first motor is equipped with a transmission device, the transmission device includes two groups of first rotating shafts arranged vertically, the first rotating roller is installed in the middle of the first rotating shaft, the first rotating roller of the same horizontal line is connected by a conveyor belt, the two sides of the first rotating shaft are installed with a second bearing, the two vertical second bearings are connected by a first telescopic rod, and the first rotating shaft The setting of the first rotating roller, conveyor belt, second bearing, first telescopic rod, first telescopic spring, second gear, first gear and first rack enables the device to cut the edges of the plywood during transmission, and the upper and lower conveyor belts compress the plywood raw materials, thus avoiding the vibration amplitude of the plywood during cutting and the occurrence of slipping during transmission, It is beneficial to ensure the quality of plywood production and improve the yield of plywood. Guarantee the quality of plywood production and improve the yield of plywood. Guarantee the quality of plywood production and improve the yield of plywood.

After the plywood is processed and formed, the four sides of the plywood need to be cut. The cutting machine is usually used to cut the plywood. The cutting machine generally includes a workbench (or operating platform). The workbench is equipped with a long, square groove, and the groove is equipped with a cutting blade. The saw blade drives the cutting blade to rotate through the motor to cut the wood. The cutting machine with this structure has the following disadvantages: first, the cutting blade is open, In the process of wood cutting, a large amount of fine wood dust is produced, and the air is greatly polluted, affecting the health of operators; Second, horizontal and vertical edge cutting are usually processed by assembly line, which requires more people and more posts to produce and process, and requires higher operating skills for employees.

The prior art discloses a fully automatic cutting equipment for plywood, which includes a transverse conveying platform and a longitudinal conveying platform. The transverse conveying platform and the longitudinal conveying platform are respectively equipped with cutting devices. The transverse conveying platform and the longitudinal conveying platform are connected in a shape of "l". The intersection of the transverse conveying platform and the longitudinal conveying platform is equipped with a plywood turning device. The plywood turning device includes a transverse sliding device, a longitudinal pushing device and a sensor, The transverse sliding device and the longitudinal pushing device are respectively equipped with several, and arranged at intervals. The sensor is set at one side of the plywood turning device to monitor the plywood reaching the designated position. The invention realizes the automatic cutting of plywood, with simple structure and novel design, which greatly improves the production efficiency and precise size control. The dust suction device is set at the cutting position, which greatly reduces the amount of dust, However, because plywood is made by gluing multi-layer boards with adhesive materials, it is easy to occur delamination of the adhesive layer due to the vibration generated during cutting, which is not conducive to the guarantee of plywood production quality and low yield.

Fully automatic edge cutting equipment for plywood to solve the problems raised in the above background technology.

In order to achieve the above purpose, the invention provides the following technical scheme: a fully automatic cutting equipment for plywood, which includes two first motors horizontally arranged, one side of the first motor is equipped with a transmission device, the transmission device includes two groups of first rotating shafts vertically arranged, the middle part of the first rotating shaft is equipped with a first rotating roller, the first rotating roller of the same horizontal line is connected by a transmission belt, and the two sides of the first rotating shaft are equipped with a second bearing, The two vertical second bearings are connected by the first telescopic rod, the first telescopic spring is installed on the outside of the first telescopic rod, the second gear is installed on the right side of the first rotating shaft, the two second gear pieces on the same side mesh, the first gear is installed on the left side of the first rotating shaft, the first gear on the same horizontal line is connected by the first rack, and the transverse cutting device is installed between the two transmission devices, The right end of the right conveyor is provided with a vertical cutting device.

As a further solution of the invention, the first bearing seat is installed on both sides of the first rotating shaft at the lower part, and the first support leg is installed at the lower end of the first bearing seat.

As a further solution of the invention, the vertical cutting device comprises a second motor, a second rotating shaft is installed on one side of the second motor, a second circular sleeve is installed on both sides of the middle of the second rotating shaft, a cutting piece is fixed on one side of the second circular sleeve, and a fixing device is installed in the second circular sleeve.
