Description

Technical Field

[0001] This utility model relates to the field of plywood processing, specifically a cutting and clamping mechanism for high-size and high-stability plywood. Background Technology

[0002] Plywood is a sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets, and then gluing them together with adhesives. It typically uses an odd number of veneer layers, with the grain direction of adjacent veneers perpendicular to each other. Plywood is a commonly used material in furniture making, and cutting is a crucial step in plywood processing.

[0003] The inventors discovered that at least the following problems remain unsolved in the existing technology: In the traditional plywood cutting process, it is usually necessary to manually operate the clamps to hold the plywood. After the plywood is cut, the clamps need to be operated again to release the plywood. This affects the cutting efficiency of the plywood and increases the labor intensity.

[0004] Therefore, we propose a high-size and high-stability plywood cutting and clamping mechanism that can automatically clamp the plywood during the cutting process and automatically release the clamp after the plywood is cut, with a high degree of automation. Utility Model Content

The mounting plate has a connecting strip welded to the middle of one side, and a toothed plate is detachably installed at the bottom end of the connecting strip. The clamping mechanism is used for automatic clamping of plywood. The clamping mechanism includes two sets of bidirectional lead screws. Limiting grooves are symmetrically opened on both sides of the upper surface of the cutting table. Limiting blocks are slidably connected to the inner side of the limiting grooves. One end of the limiting block, located outside the limiting groove, is welded to the middle of the bottom side of the clamping plate. The bidirectional lead screw horizontally passes through the middle of the limiting block and is threadedly connected to it. A gear is fixedly installed at one end of the bidirectional lead screw located outside the cutting table. The gears at one end of each of the two sets of bidirectional lead screws mesh with both sides of the toothed plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model controls the operation of an electro-hydraulic actuator. The mounting plate pushes the cutting blade downward to cut the plywood on the surface of the cutting table.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] A cutting and clamping mechanism for high-size, high-stability plywood, see [link / reference]. Figures 1 to 3The system includes a cutting table 1, with a cutting blade 11 vertically mounted at the center of the upper part of the cutting table 1. Two sets of inverted L-shaped clamping plates 2 are symmetrically arranged on both sides of the upper surface of the cutting table 1. A cutting groove 15 is horizontally opened at the center of the upper surface of the cutting table 1, and the bottom end of the cutting blade 11 is movably connected to the cutting groove 15. A cutting mechanism is used for cutting plywood. The cutting mechanism includes an electro-hydraulic push rod 14, a bracket 12 welded to the center of the upper surface of the cutting table 1, and a mounting plate 13 horizontally arranged on the inner side of the bracket 12. The cutting blade... The top of 11 is fixedly connected to the lower surface of the mounting plate 13, the telescopic end of the electro-hydraulic actuator 14 is fixedly connected to the middle of the upper surface of the mounting plate 13, the electro-hydraulic actuator 14 is fixedly connected to the middle of the upper surface of the bracket 12, the bracket 12 is inverted U-shaped, a connecting strip 16 is welded to the middle of one side of the mounting plate 13, a connecting groove 18 is vertically opened through the middle of one side of the bracket 12, the connecting strip 16 is slidably connected to the connecting groove 18, the connecting strip 16 is inverted L-shaped, and a toothed plate 17 is detachably installed at the bottom end of the connecting strip 16.

[0021] The plywood to be cut is placed horizontally on the upper surface of the cutting table 1 and between the clamping plates 2 on both sides of the cutting table 1. The electro-hydraulic push rod 14 is controlled by the corresponding controller to push the cutting blade 11 on the bottom side of the mounting plate 13 to move downwards. The plywood can be effectively cut through the cutting groove 15 in the middle of the upper surface of the cutting table 1. During the process of the electro-hydraulic push rod 14 pushing the cutting blade 11 downwards, the toothed plate 17 can be pushed downwards through the connecting strip 16 on one side of the mounting plate 13.

[0022] For details, see Figures 1 to 2 Clamping mechanism: used for automatic clamping of plywood. The clamping mechanism includes two sets of bidirectional lead screws 23. Limiting grooves 21 are symmetrically opened on both sides of the upper surface of the cutting table 1. Limiting blocks 22 are slidably connected to the inner side of the limiting grooves 21. The end of the limiting block 22 placed outside the limiting groove 21 is welded to the middle of the bottom side of the clamping plate 2. The bidirectional lead screw 23 passes horizontally through the middle of the limiting block 22 and is threadedly connected to the limiting block 22. The bidirectional lead screw 23 is rotatably connected to the cutting table 1 through bearings. A gear 24 is fixedly installed on the end of the bidirectional lead screw 23 placed outside the cutting table 1. The gears 24 at one end of the two sets of bidirectional lead screws 23 respectively mesh with the two sides of the toothed plate 17.

[0023] Gears 24 mesh with both sides of the toothed plate 17. As the toothed plate 17 moves downward, it drives two sets of gears 24 to rotate, thereby driving the bidirectional lead screw 23 in the middle of the two sets of gears 24 to rotate. The bidirectional lead screw 23 is threadedly connected to the limiting blocks 22 inside the two sets of limiting grooves 21. As the bidirectional lead screw 23 rotates, it drives the two sets of limiting blocks 22 to move relative to each other, further driving the clamping plates 2 on both sides of the upper surface of the cutting table 1 to move relative to each other, thereby automatically clamping and fixing the plywood to be cut on the upper surface of the cutting table 1. It should be noted that when the mounting plate 13 continues to move downward... The connecting bar 16 can push the toothed plate 17 to move to the bottom side of the gear 24 and separate it from the gear 24. Subsequently, the electro-hydraulic push rod 14 can continue to push the cutting blade 11 on the bottom side of the mounting plate 13 to move downward to cut the plywood on the surface of the cutting table 1. Conversely, when the electro-hydraulic push rod 14 drives the cutting blade 11 to move upward to reset, the connecting bar 16 drives the toothed plate 17 to move upward to reset, which can drive the two sets of gears 24 to rotate in opposite directions, and further drive the clamping plates 2 on both sides of the upper surface of the cutting table 1 to move in opposite directions, thereby automatically releasing the clamping of the plywood and facilitating the collection of the plywood after cutting.

[0024] Further, see Figures 1 to 3 A mounting groove 3 is vertically provided in the middle of the top of the toothed plate 17. A first fixing hole 31 is provided on the front side of the lower end of the connecting strip 16. A second fixing hole 32 is provided through the front side of the mounting groove 3. The lower end of the connecting strip 16 is inserted into the mounting groove 3, and the connecting strip 16 and the toothed plate 17 are fixedly connected by bolts 33 through the first fixing hole 31 and the second fixing hole 32.

[0025] The connecting strip 16 and the toothed plate 17 are fixedly connected by bolts 33 through the first fixing hole 31 and the second fixing hole 32. By removing the bolts 33, toothed plates 17 of different sizes can be replaced according to the size of the plywood, thereby controlling the movement stroke of the clamping plate 2 and enabling clamping operations on plywood of different sizes.

[0026] It is worth noting that, see Figures 1 to 2 The threads on the outer sides of the two sets of bidirectional lead screws 23 are in opposite directions.

[0027] Since the two sets of gears 24 mesh with the two sides of the toothed plate 17 respectively, the two sets of gears 24 rotate in opposite directions during the up and down movement of the toothed plate 17. In order to ensure that the clamping plates 2 on both sides of the upper surface of the cutting table 1 move relative to each other, the threads on the outer sides of the two sets of bidirectional lead screws 23 need to be set in opposite directions.

[0028] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
