Description

Technical Field

[0001] This utility model relates to the field of plywood processing technology, specifically to a plywood cutting device. Background Technology

[0002] Unlike traditional single-piece wood boards, plywood is a material that uses adhesive to bond multiple pieces of wood together. This saves resources and increases the thickness of the boards. Even if the raw wood is damaged, it can be cut into thin boards and spliced ​​together to prevent the wood from becoming unusable due to minor defects.

[0003] To cut plywood into different sizes, cutting devices are often used to saw the boards. However, in the past, such devices required workers to manually press and push the boards to contact the saw blade. The edges of the cut boards were not very smooth, and it was quite inconvenient to assemble them if there were any deviations.

[0004] Now, a novel plywood cutting device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a plywood cutting device to solve the problem of lack of board positioning mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plywood cutting device, comprising a worktable and slots. Slots are respectively provided on the left side of the front and rear ends of the worktable, and sliders are movably connected in the slots. Steel balls are embedded in the top and bottom of the sliders. A push plate is fixed above the outer side of the sliders, and a handle is fixed at the bottom left side of the push plate. A sliding chamber is provided between the front and rear sides of the lower inner side of the push plate, and a bidirectional lead screw is assembled between the front and rear sides inside the sliding chamber. Engaging blocks are respectively sleeved at the front and rear ends of the bidirectional lead screw. A locking block is fixed on the right side of the engagement block. A plywood board is horizontally placed on the top of the worktable. A storage box is attached to the lower right side of the worktable, and bolts are threadedly connected to both sides of the storage box.

[0007] Preferably, the meshing block and the locking block are on the same vertical plane, and the meshing block can be synchronously retracted and dispersed under the rotation of the bidirectional lead screw.

[0008] Preferably, the slider is symmetrically fixed at both ends below the push plate, and the slider can slide left and right along the inner wall of the slot.

[0009] Preferably, a through groove is provided on the right side inside the workbench, and a support cylinder is inserted into the center of the through groove. A bushing is fitted at the front end of the top of the support cylinder, and an electric saw blade is installed in the bushing. An assembly is provided at the center of the lower part of the storage box, and a screw is movably connected in the assembly. An assembly block is fixed at the bottom of the support cylinder, and insertion holes are provided on both sides inside the assembly block. Two sets of thin rods are fixed between the storage box and the workbench.

[0010] Preferably, the thin rod is embedded in the insertion hole, and the top of the screw is embedded in the threaded cavity of the support cylinder.

[0011] Preferably, the support cylinder can slide up and down along the inner wall of the through groove, and the electric saw blade can rotate vertically above the support cylinder.

[0012] Preferably, a dust collection box is provided on the left side of the bottom of the storage box, and angle steel is installed between the two sides of the dust collection box and the storage box. An air groove is provided on the left side of the dust collection box, and a mesh is fixed in the air groove. An exhaust fan is installed on the lower left corner of the outside of the dust collection box.

[0013] Preferably, the air inlet of the exhaust fan is fitted into the air duct, and the dust collection box is connected to the storage box.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this plywood cutting device not only achieves precise cutting of boards and adjustment of cutting depth, but also achieves cleaning of residual debris;

[0015] (1) By fixing a push plate above the outer side of the slider, the left side of the plywood plate is attached to the right side of the push plate. Rotate the exposed double screw, and along the sliding chamber inside the push plate, the locking block fixed by the meshing block is closed in the opposite direction, and the plywood plate overlapping on the worktable surface is locked. Then hold the handle and move horizontally along the slots at the front and rear ends of the worktable. Because the surface of the slider is inlaid with steel balls, the frictional resistance between the push plate and the slot can be reduced, forcing the plywood plate to approach the electric saw blade for cutting.

[0016] (2) By installing an electric saw blade in the bushing, rotating the screw at the center of the bottom of the storage box, because the insertion holes on both sides of the assembly block are connected to the outside of the thin rod, rotating the screw can vertically lift or sink the support cylinder with internal threads, and pull the bushing at the top and the electric saw blade longitudinally into and out of the through groove, thereby changing the depth of the electric saw blade cutting the plywood, so that the device can cut plywood of different thicknesses.

[0017] (3) A dust collection box is installed on the left side of the bottom of the storage box. The dust collection box is attached to the lower left of the storage box and connected to the bottom of the storage box with an open slot. Then, the exhaust fan installed on the surface of the air slot on the left side is turned on to draw wood chips through the mesh from the through slot of the workbench. The wood chips are collected in the dust collection box after passing through the storage box, which prevents the materials from scattering everywhere and causing pollution. After that, the angle iron can be removed to empty the garbage in the dust collection box. Attached Figure Description

The slider 24 is symmetrically fixed at the front and rear ends below the push plate 3. The slider 24 can slide left and right along the inner wall of the slot 6.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the left side of the plywood plate 5 is attached to the right side of the push plate 3. The exposed double-acting screw 22 is rotated and moves along the sliding chamber 23 on the inner side of the push plate 3 to engage the locking block 4 fixed by the meshing block 21, thereby locking and fixing the plywood plate 5 on the surface of the workbench 1. Then, the handle 2 is held and moved horizontally along the slots 6 at both ends of the workbench 1 to smoothly and accurately assist the plywood plate 5 in approaching the electric saw blade 7.

[0027] Example 2: A through groove 9 is provided on the right side inside the workbench 1, and a support cylinder 20 is inserted into the center of the through groove 9. A bushing 8 is fitted at the front end of the top of the support cylinder 20, and an electric saw blade 7 is installed in the bushing 8. A mounting kit 12 is provided at the center of the lower part of the storage box 10, and a screw 13 is movably connected in the mounting kit 12. An assembly block 19 is fixed at the bottom of the support cylinder 20, and insertion holes 18 are provided on both sides inside the assembly block 19. Two sets of thin rods 11 are fixed between the storage box 10 and the workbench 1.

[0028] The thin rod 11 is embedded in the insertion hole 18, and the top of the screw 13 is embedded in the threaded cavity of the support cylinder 20. The support cylinder 20 can slide up and down along the inner wall of the through groove 9, and the electric saw blade 7 can rotate vertically above the support cylinder 20.

[0029] Specifically, such as Figure 1As shown, the screw 13 at the bottom center of the rotating storage box 10, because the insertion holes 18 on both sides of the assembly block 19 are sleeved on the outside of the thin rod 11, can vertically lift or sink the support cylinder 20 with internal threads when the screw 13 is rotated, and pull the top bushing 8 and the electric saw blade 7 longitudinally into and out of the through groove 9, thereby changing the depth of the electric saw blade 7 cutting the plywood board 5.

[0030] Example 3: A dust collection box 14 is provided on the left side of the bottom of the storage box 10, and angle steel 27 is installed between the two sides of the dust collection box 14 and the storage box 10.

[0031] Specifically, such as Figure 1 and Figure 4 As shown, the dust collection box 14 is attached to the lower left of the storage box 10 and is connected to the bottom of the storage box 10 through an open slot. Then, the exhaust fan 16 mounted on the surface of the left air slot 26 is turned on, and the sawdust is drawn from the through slot 9 of the workbench 1 through the mesh 15. The sawdust is collected in the dust collection box 14 after passing through the storage box 10, so as to prevent the material from scattering everywhere and causing pollution.

[0032] Working principle: When using this utility model, firstly, the left side of the plywood plate 5 is attached to the right side of the push plate 3. Rotate the exposed bidirectional screw 22 and slide along the sliding chamber 23 on the inner side of the push plate 3 to retract the locking block 4 fixed by the meshing block 21, thereby locking and fixing the plywood plate 5 on the surface of the workbench 1. Then, hold the handle 2 and move it horizontally along the slots 6 at both ends of the workbench 1. Because the surface of the slider 24 is inlaid with steel balls 25, it can reduce the frictional resistance between the push plate 3 and the slot 6, and smoothly and accurately assist the plywood plate 5 to approach the electric saw blade 7. Before rotating the screw 13 at the center of the bottom of the storage box 10, because the insertion holes 18 on both sides of the assembly block 19 are sleeved on the outside of the thin rod 11, rotating the screw 13 can vertically lift or sink the support cylinder 20 with internal threads, and pull the top bushing 8 and the electric saw blade 7 longitudinally into and out of the through groove 9, thereby changing the cutting depth of the plywood plate 5 by the electric saw blade 7.
