Description

Technical Field

[0001] This utility model relates to the field of wood sanding, and in particular to a sanding device for the production and processing of plywood. Background Technology

[0002] Currently, sanding is a key process in the production and processing of plywood, aiming to make the surface of the plywood smooth and flat to meet the requirements of subsequent processing or use. Traditional plywood sanding equipment has the following problems:

[0003] Fixed sanding height: The height of the sanding mechanism cannot be adjusted according to the actual thickness or curvature of the plywood, which makes it impossible to achieve precise sanding for plywood of different specifications. Frequent equipment changes or manual adjustments are required, resulting in low production efficiency.

[0004] Unstable board fixing: The simple pressure plate structure used to fix the plywood lacks an adjustable clamping force design, resulting in poor fixing effect on plywood of different thicknesses. It is easy to slip during sanding, affecting the processing quality.

[0005] Based on this, we propose a sanding device for woodworking production and processing. Utility Model Content

[0006] To solve the technical problems of fixing the sanding height and the unstable fixing of the wood board, this utility model provides a sanding device for woodworking production and processing.

[0007] The present invention is achieved by the following technical solution: a sanding device for woodworking production and processing, including a support frame, an installation table fixedly installed above the support frame, a sanding mechanism connected above the installation table via a height adjustment component, a wood board reciprocating movement mechanism fixedly installed on the surface of the installation table, and a wood board clamping mechanism fixedly connected above the wood board reciprocating movement mechanism.

[0008] The grinding mechanism includes a fixed frame, a connecting platform fixedly connected to the top of the fixed frame, a motor connected to the top of the connecting platform, a mounting plate installed at the bottom of the motor, mounting holes on the surface of the mounting plate, and the mounting plate and the fixed frame locked together by bolts passing through the mounting holes. The output end of the motor is connected to a drive shaft, and a grinding wheel is fitted on the surface of the drive shaft.

[0009] The height adjustment assembly includes a support frame, which is fixedly connected to the outside of the mounting platform. A cylinder is fixedly connected to the support frame, and a piston rod is connected to the output end of the cylinder. A support frame is fixedly connected to the top end of the piston rod.

[0010] The reciprocating movement mechanism for the wooden board includes a fixed base, with a slide rod fixedly connected through the inner side of the fixed base. A sanding table for sanding the surface of the wooden board is slidably sleeved on the surface of the slide rod, and a push handle is fixedly connected to the outer side of the sanding table. There are two slide rods, parallel to each other, passing through the fixed base and located on the same horizontal plane. The sanding table is slidably connected to the slide rods through a linear bearing.

[0011] The wooden board clamping mechanism includes a connecting frame. The bottom end of the connecting frame is fixedly connected to the side of the sanding table. A threaded sleeve is fixedly connected to the top end of the connecting frame. A screw rod passes through the inner thread of the threaded sleeve. A handle is connected to the top end of the screw rod. A positioning block is fixedly connected to the bottom end of the screw rod.

[0012] As a further optimization of this utility model, the support frame serves as the basic support structure, fixing the mounting surface to provide a stable working plane. The sanding mechanism is connected to the mounting surface via a height adjustment component, allowing the angle to be adjusted according to sanding requirements; the wood board reciprocating movement mechanism cooperates with the wood board clamping mechanism to achieve the fixing and reciprocating movement of the plywood, forming a complete sanding work path.

[0013] As a further optimization of this utility model, the mounting holes are distributed in a circumferential array on the surface of the mounting plate, and the number is not less than 2, for detachably fixing the mounting plate to the fixing frame by bolts.

[0014] As a further optimization of this utility model, the motor is fixed to the mounting plate and the fixing bracket with bolts. After starting, it drives the transmission shaft to rotate at high speed, which in turn drives the grinding wheel to grind the surface of the plywood. The array distribution design of the mounting holes ensures the stability of the motor installation and supports disassembly and maintenance.

[0015] As a further optimization of this utility model, the cylinder drives the piston rod to extend and retract, and the piston rod drives the fixed frame mounted on it to move, thereby driving the fixed frame to lift and lower, so as to realize the height adjustment of the sanding mechanism to adapt to the sanding needs of wood boards of different thicknesses.

[0016] As a further optimization of this utility model, the sanding table is slidably connected to two parallel sliding rods via linear bearings. The operator pushes the handle to move the sanding table back and forth along the sliding rods. The fixed base provides rigid support for the sliding rods, ensuring smooth movement and allowing the wood panel surface to pass evenly under the sanding wheel for complete sanding.

[0017] As a further optimization of this utility model, the wooden board is placed on the surface of the sanding table and fixed by the wooden board clamping mechanism. Turning the handle drives the screw to move up and down in the threaded sleeve, causing the positioning block to press or release the plywood, ensuring that plywood of different thicknesses is stably fixed.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model is equipped with a height adjustment component. Through the operation of the cylinder, the cylinder drives the piston rod to extend and retract. The piston rod drives the fixed frame installed on it to move, and drives the fixed frame to lift and lower, so as to realize the height adjustment of the sanding mechanism to adapt to the sanding needs of wood boards of different thicknesses.

[0020] 2. This utility model uses a wooden board clamping mechanism including a connecting frame, a threaded sleeve, and a screw. Rotating the handle allows the screw to move within the threaded sleeve, causing the positioning block to press or release the wooden board. The clamping force can be adjusted according to the thickness of the wooden board, solving the problem of poor fixing effect of traditional pressure plate structures. This ensures stable fixing of wooden boards of different thicknesses, prevents slippage during sanding, and improves processing quality.

[0021] 3. The sanding table of this utility model is slidably connected to two parallel sliding rods via a linear bearing. The operator can push the handle to make the sanding table move back and forth smoothly along the sliding rods. The fixed seat provides rigid support for the sliding rods, allowing the surface of the wooden board to pass evenly under the sanding wheel, achieving comprehensive sanding. The operation is convenient and ensures uniform sanding effect. Attached Figure Description

[0039] Working principle

[0040] Overall structural coordinated operation

[0041] The support frame 1 serves as the basic support structure, fixing the mounting table 2 to provide a stable working surface. The sanding mechanism 3 is connected to the mounting table 2 via a height adjustment component, allowing the angle to be adjusted according to sanding requirements. The wood board reciprocating movement mechanism 4 works in conjunction with the wood board clamping mechanism 5 to achieve the fixing and reciprocating movement of the plywood, forming a complete sanding work path.

[0042] Drive and adjustment of the grinding mechanism

[0043] Power transmission: The motor 33 is bolted to the mounting plate 34 and the fixing bracket 31. After starting, it drives the transmission shaft 36 to rotate at high speed, which in turn drives the grinding wheel 37 to grind the surface of the plywood. The array distribution design of the mounting holes 35 ensures the stability of the motor 33 installation and supports disassembly and maintenance.

[0044] Height adjustment: The support frame 38 of the height adjustment component is fixed to the mounting platform 2. Through the operation of the cylinder 39, the cylinder 39 drives the piston rod 310 to extend and retract. The piston rod 310 drives the fixed frame 31 installed on it to move, and drives the fixed frame 31 to lift and lower, so as to realize the height adjustment of the sanding mechanism 3 to adapt to the sanding needs of wood boards of different thicknesses.

[0045] Fixing and reciprocating movement of plywood

[0046] Clamping and fixing: The wooden board is placed on the surface of the sanding table 43 and fixed by the wooden board clamping mechanism 5. Turning the handle 54 drives the screw 53 to move up and down in the threaded sleeve 52, which drives the positioning block 55 to press or release the wood board, ensuring that wood boards of different thicknesses are stably fixed.

[0047] Reciprocating movement: The sanding table 43 is slidably connected to two parallel slide rods 42 via linear bearings.
