Description

Technical Field

[0001] The invention relates to the field of plywood, in particular to a roller-coating glue coating machine for plywood. Background Art

[0002] Plywood is a three-layer or multi-layer plate-like material made by peeling or planing wood segments into thin wood and then gluing them together. It is usually made of an odd number of veneers, and the fibers of adjacent veneers are glued together. Existing plywood processing and gluing equipment is usually provided with a collecting bucket, which collects the glue drops spilled during the gluing process of the plywood and guides the glue liquid into a collecting box to avoid waste of glue liquid resources. In addition, the plywood processing and gluing equipment is also provided with a filter screen to filter the glue liquid. However, during the long-term use of the plywood processing and gluing equipment, the glue liquid in the collecting box is easy to solidify, and then after the gluing work is completed, it is inconvenient to pour out the glue liquid in the collecting box; there are also existing plywood processing and gluing equipment When the equipment is in use, a rubber roller is used to apply glue to the plywood. During use, the rubber roller needs to be driven by a motor to rotate. The rotating rubber roller can effectively apply glue to the plywood. However, during use, the motor that drives the rubber roller can only drive the rubber roller to rotate. During use, the height of the rubber roller needs to be adjusted according to the different thicknesses of the plywood. When adjusting the height of the rubber roller, the height of the motor that drives the rubber roller will also be adjusted. The motor needs to be connected to a power cord. When adjusting the height of the motor, it is inevitable that the power cord connected to the motor will be pulled. In the process of pulling the power cord, the power cord will inevitably be lost. For this reason, we propose a plywood roller coating gluing machine. Summary of the invention

The rotation of the multiple groups of stirring blades 15 will continuously stir the glue in the glue box 12, thereby relieving the solidification of the glue in the glue box 12 within a certain period of time.

[0027] The bottom of the glue box 12 is evenly connected to multiple groups of lower glue hoses 17, and each of the lower glue hoses 17 is installed with a group of electric glue valves 18. The lower glue hoses 17 are located above the glue roller 4.

[0028] A plurality of through holes 19 are evenly arranged in the middle of the workbench 1, the through holes 19 are located above the collecting bucket 1001, and the rubber roller 4 is located above the through holes 19; during use, the glue dripping from the rubber roller 4 can enter the collecting bucket 1001 through the through holes 19 evenly arranged on the workbench 1.

[0029] A group of hydraulic cylinders 20 are respectively fixedly installed on the two groups of support platforms 2, and the telescopic ends of the two groups of hydraulic cylinders 20 are respectively fixedly connected to a group of lifting blocks 3. When in use, the two groups of hydraulic cylinders 20 are started to drive the two groups of lifting blocks 3 to move up and down, thereby adjusting the height of the rubber roller 4; in the process of adjusting the height of the rubber roller 4, the up and down movement of the lifting blocks 3 will drive the fixing frame 5 to move up and down, and the up and down movement of the fixing frame 5 will drive the rotating column 6 to move up and down along the hexagonal rod in the middle section of the rotating part 8, thereby ensuring that the two groups of bevel gears 7 can always mesh with each other, and the rotating part 8 can drive the rotating column 6 to rotate when it rotates.

[0030] The rotating member 8 is rotatably connected to two groups of stabilizing seats 21 via bearings. The two groups of stabilizing seats 21 are respectively fixedly mounted on the outer walls of the workbench 1 and the glue box 12 . The two groups of stabilizing seats 21 ensure a stable mounting structure of the rotating member 8 .

[0031] A set of supporting legs 22 are fixedly installed at the four corners of the bottom of the workbench 1; the four sets of supporting legs 22 can provide strong support for the workbench 1 to ensure the stability of the structure of the workbench 1.

[0032] A hydraulic cylinder 23 is fixedly installed on the top of the workbench 1, and the telescopic end of the hydraulic cylinder 23 is fixedly connected to a push plate 24.

When in use, the plywood is placed on the top of the workbench 1, and the hydraulic cylinder 23 is started to drive the push plate 24 to move. The movement of the push plate 24 can drive the plywood to move on the top of the workbench 1, and the plywood will pass under the rubber roller 4 when moving, and then the rubber roller 4 will be used to apply glue to the plywood.

[0033] Working principle of the present invention: before use, according to the thickness of the plywood, two groups of hydraulic cylinders 1 20 are started to drive two groups of lifting blocks 3 to move up and down respectively, so that the height of the rubber roller 4 can be adjusted to make the height of the rubber roller 4 appropriate, ensuring that the rubber roller 4 can effectively apply glue to the plywood when the plywood passes through the bottom of the rubber roller 4; when in use, the plywood is placed on the top of the workbench 1, and the hydraulic cylinder 2 23 is started to drive the push plate 24 to move. The movement of the push plate 24 can drive the plywood to move on the top of the workbench 1, and the plywood will pass under the rubber roller 4 when moving, and then the plywood is applied with glue by the rubber roller 4. Before the glue is applied by the rubber roller 4, the electric glue valve 2 18 is opened, and the glue in the glue box 12 can drip onto the outer wall of the rubber roller 4 through the lower rubber hose 17, ensuring that the plywood can be effectively applied with glue when the rubber roller 4 rotates;

[0034] When the plywood passes through the rubber roller 4, the motor 9 is started to drive the rotating member 8 to rotate, and the rotation of the rotating member 8 can drive the rotating column 6 to rotate. The rotating column 6 rotates and, under the transmission action of the two sets of mutually meshing bevel gears 1 7, drives the rubber roller 4 to rotate. The rubber roller 4 rotates and cooperates with the glue dripping from the lower rubber hose 17 to effectively apply glue to the plywood; and the rotating member 8 rotates and, under the transmission action of the two sets of mutually meshing bevel gears 2 16, drives the stirring rod 14 to rotate. The rotation of the stirring rod 14 drives the multiple sets of stirring blades 15 to rotate. The rotation of the multiple sets of stirring blades 15 will continuously stir the glue in the glue box 12, thereby relieving the solidification of the glue in the glue box 12 within a certain period of time;

[0035] During the gluing operation, the glue roller 4 and the glue dripping on the plywood can enter the collecting bucket 1001 through the through hole 19, and the glue in the collecting bucket 1001 will gradually slide down and fall into the collecting box 1005, so that the glue can be recycled to reduce the waste of glue. After the glue enters the collecting box 1005, the glue can be filtered through the filter 1006, and at this time, the rotation of the rotating member 8 will drive the pulley 1009 to rotate, and the rotation of the pulley 1009 will drive the rotating ring 1003 to rotate along the fixed ring 1002 under the transmission action of the belt 1010, and the rotation of the rotating ring 1003 will drive the collecting box 1005 to rotate, and the rotation of the collecting box 1005 will drive the collecting box 100 The glue in the collecting box 1005 is continuously shaken, thereby relieving the solidification of the glue in the collecting box 1005 within a certain period of time, and the rotation of the collecting box 1005 will also drive the filter screen 1006 to rotate. The rotation of the filter screen 1006 can make the suspended particles in the glue fall on different positions at different times, avoiding excessive accumulation in a certain area and causing blockage; when the gluing work is completed, the electric glue valve 1008 can be opened, and then the glue in the collecting box 1005 can be discharged through the drain pipe 1007 for easy recycling; when necessary, the fixing bolt 1004 can be removed by using tools, and then the entire collecting box 1005 can be removed, which is convenient for the maintenance of the collecting box 1005.

[0036] It should be noted that the present invention requires an external suitable controller and power supply when used. The external controller can control the operation of the motor 9, hydraulic cylinder 1 20, hydraulic cylinder 2 23, electric glue valve 2 18 and electric glue valve 1 1008, and the external power supply provides power for the operation of the motor 9, hydraulic cylinder 1 20, hydraulic cylinder 2 23, electric glue valve 2 18 and electric glue valve 1 1008; it should be noted that the electric glue valve 2 18 and the electric glue valve 1 1008 are both existing mature technologies and will not be described in detail here; it should be noted that the motor 9 needs to adopt a motor that meets the driving requirements of the device of the present invention.

It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the scope of protection determined by the claims submitted for the present invention.
