Description

Technical Field

[0001] This application relates to the field of plywood production equipment technology, and in particular to an automatic plywood coating machine. Background Technology

[0002] A plywood gluing machine is a piece of equipment used in the production of plywood. Its main function is to apply glue to the surface of wood to bond wood chips or veneers together to form plywood. This machine can apply glue evenly and precisely, ensuring that the wood is firmly bonded during pressing. Plywood gluing machines are usually important pieces of equipment in wood processing plants for large-scale plywood production.

[0003] Existing automatic plywood coating machines lack pre-positioning measures for the plywood during production. Plywood is made up of multiple layers of veneer glued together. If the plywood cannot be centered, the veneer layers are prone to misalignment during pressing, resulting in uneven internal structure of the finished product and affecting mechanical properties such as bending strength and shear resistance. Summary of the Invention

[0004] The purpose of this application is to provide an automatic plywood coating machine to solve the above problems, which has a measure to pre-position the plywood to ensure that the plywood can be aligned during pressing, so as to make the internal structure of the finished product uniform and reduce material waste caused by subsequent cutting.

[0005] This application achieves the above objectives through the following technical solutions:

[0006] An automatic plywood coating machine, comprising:

[0007] The positioning frame is a rectangular frame structure.

[0008] The positioning cylinders are installed at two opposite corners of the positioning frame, and the output ends of the positioning cylinders are both facing the center of the positioning frame.

[0009] The positioning plate is fixedly connected to the output end of the positioning cylinder.

[0010] A connecting bracket, which is fixedly connected to the top of the positioning frame;

[0011] The suction device has a hollow structure with airflow holes at the bottom and multiple sliding rods fixedly connected to the top of the suction device.

[0012] The lifting cylinder is fixedly connected to the mounting beam, and the mounting beam is connected to a linear drive assembly that drives its translation.

[0013] The slide rod passes through the connecting frame and slides with the connecting frame. A limit block is fixedly connected to the top of the slide rod. A spring is sleeved on the slide rod and the spring is located between the limit block and the connecting frame.

[0014] The connecting frame has a clearance hole through which the output end of the lifting cylinder can pass, and the lifting cylinder passes through the output end of the connecting frame and is fixedly connected to the suction device.

[0015] Furthermore, the linear drive assembly includes: a gantry frame fixed on a base, a linear slide fixedly mounted on the gantry frame, and an output end of the linear slide fixedly connected to a mounting beam.

[0016] Furthermore, the absorber has a hollow structure with an internal airflow channel and airflow holes evenly distributed on its bottom surface.

[0017] Furthermore, it also includes a first conveyor and a second conveyor, both of which are located below the positioning frame, and the glue applicator is located above the first conveyor.

[0018] Furthermore, the positioning plate is L-shaped, and the connecting frame is cross-shaped.

[0019] Furthermore, the bottom of the suction device is flat.

[0020] Compared to existing technologies, this application has a positioning cylinder and two L-shaped positioning plates that can be driven by the cylinder. By clamping, the plate is pre-positioned to ensure that the plate is aligned during pressing, resulting in a uniform internal structure of the finished product and reducing material waste caused by subsequent cutting.

[0029] like Figure 1-3 As shown, an automatic plywood coating machine includes:

[0030] The system comprises: a positioning frame 9, which is a rectangular frame structure; positioning cylinders 10, which are installed at two opposite corners of the positioning frame 9, with their output ends facing the center of the positioning frame 9; a positioning plate 11, which is fixedly connected to the output ends of the positioning cylinders 10; a connecting frame 3, which is fixedly connected to the top of the positioning frame 9; a suction device 4, which is a hollow structure with airflow holes 5 at its bottom, and multiple sliding rods 6 fixedly connected to its top; a lifting cylinder 2, which is fixedly connected to the mounting beam 1, and the mounting beam 1 is connected to a linear drive assembly that drives its translation; wherein, the sliding rods 6 pass through the connecting frame 3 and slide in cooperation with the connecting frame 3, and a limit block 8 is fixedly connected to the top of the sliding rods 6, and a spring 7 is sleeved on the sliding rods 6, with the spring 7 located between the limit block 8 and the connecting frame 3; the connecting frame 3 has a clearance hole 18 that allows the output end of the lifting cylinder 2 to pass through, and the lifting cylinder 2 passes through the output end of the connecting frame 3 and is fixedly connected to the suction device 4.

[0031] Specifically, the board material can be placed inside the positioning frame 9. Driven by the positioning cylinder 10, the positioning plate 11 can move towards the center of the positioning frame 9, and then push the board material to be centered for positioning. The output end of the lifting cylinder 2 can extend and retract through the clearance hole 18. Driven by the lifting cylinder 2, the suction device 4 can first descend. At this time, the slide rod 6 follows and compresses the spring 7. The spring 7 pushes the connecting frame 3 to descend. The positioning frame 9 first contacts the board material conveying equipment below. The lifting cylinder 2 extends further. Then the suction device 4 contacts the board material and adsorbs the board material. The lifting cylinder 2 retracts, the suction device 4 rises, and the positioning frame 9 rises. The linear drive assembly drives the mounting beam 1 to translate. The board material follows the translation. Repeating the above operation can bond the glued board material and the adsorbed board material together and apply pressure to connect them tightly to complete the plywood production.

[0032] Furthermore, the linear drive assembly includes: a gantry frame 12, which is fixed on the base 14; a linear slide 13 is fixedly mounted on the gantry frame 12; and the output end of the linear slide 13 is fixedly connected to the mounting beam 1.

[0033] Specifically, the gantry frame 12 supports the horizontal installation of the linear slide 13, enabling the horizontal movement of the mounting beam 1.

[0034] Furthermore, the absorber (4) has a hollow structure with an airflow channel inside and airflow holes (5) evenly distributed on its bottom surface.

[0035] Specifically, the suction device 4 is connected to a vacuum pump, which generates negative pressure inside the pump, thereby sucking up the board material and moving it.

[0036] Furthermore, it also includes a first conveyor 15 and a second conveyor 16, both of which are located below the positioning frame 9, and a glue applicator 17 is located above the first conveyor 15.

[0037] Specifically, the glue applicator 17 can apply adhesive to the board material passing below, and the second conveyor 16 transports the board material to be bonded. Through suction and transfer, the board material is bonded to the glued board material to form plywood.

[0038] Furthermore, the positioning plate 11 is L-shaped and can push the two sides of the plate, while the connecting frame 3 is cross-shaped.

[0039] Furthermore, the bottom of the suction device 4 is flat, allowing it to fit snugly against the substrate.

[0040] In the above structure, the first conveyor 15 and the second conveyor 16 transport the boards. The glue applicator 17 applies adhesive to the boards. The linear slide table 13 drives the mounting beam 1 to translate, so that the positioning frame 9 is moved above the second conveyor 16. Then, the lifting cylinder 2 drives the suction device 4 to descend, and at the same time, the positioning frame 9 descends. The positioning frame 9 first contacts the second conveyor 16. The positioning cylinder 10 drives the positioning plate 11 to translate, so that the two positioning plates 11 push the board to the center. Then, the positioning cylinder 10 retracts, and the suction device 4 continues to descend. At this time, the slide rod 6 follows the suction device 4 to descend and compresses the spring 7 through the limit block 8. After the suction device 4 contacts the board, it sucks up the board through negative pressure. Then, the lifting cylinder 2 is activated to drive the suction device 4 to rise. At this time, the compressed spring 7 pushes to return the positioning frame 9 to its position. When it moves to the first conveyor 15, the above operation is repeated to position the board coated with adhesive. Then, the two boards are bonded together. At the same time, the suction device 4 applies pressure to the two boards to ensure that the boards are tightly connected, thus realizing the production of plywood.
