technical field

The invention belongs to the field of equipment for processing and producing decorative effects, and in particular relates to a door panel engraving device.

Background technique

Door panel is a kind of furniture processing material, which is mainly made of natural logs or solid wood through drying, blanking, polishing, grinding and other processes. Door panels are often used as raw materials for furniture door processing. To process door panels into furniture doors usually requires a certain amount of decorative treatment, among which engraving patterns and characters on the door panels is a commonly used decoration method.

Traditional door panel engraving is done manually. Before engraving, it is necessary to draw the pattern to be engraved on the door panel, and then manually hold the carving knife to carve the set shape or pattern on the door panel. The processing efficiency of this method is low, and there is a certain subjectivity in manual engraving, which will cause errors between the engraved pattern and the original pattern, and cannot be mass-produced.

In order to solve the above technical problems, a CNC engraving device has appeared, which mainly includes a bed, a limit block, a knife rest and a numerical control mechanism that drives the knife rest to move. There are two limit blocks, which are slidably connected to the bed, and the knife rest There is a carving knife on it. When in use, place the door panel on the bed, slide the limit block so that the two limit blocks clamp the door panel, start the numerical control mechanism, and the numerical control mechanism controls the movement of the knife rest on the bed, so that the carving knife and the door panel move relatively , to realize the engraving of the door panel. The technical solution is set by removing the driving path of the numerical control mechanism, which can make the patterns of each engraving consistent and can be mass-produced.

But also there is following technical problem in above-mentioned technical scheme: 1, can produce a large amount of debris in the process of engraving door panel, and above-mentioned device can not carry out timely cleaning to debris in the process of engraving, may cause debris to adhere to The surface of the engraving knife will affect the engraving of the door panel, resulting in low engraving accuracy; 2. When the engraving knife is engraving the door panel, it will give the door panel a force to move forward, and the door panel cannot be firmly fixed only by two limit blocks.

Contents of the invention

The present invention aims to provide a door panel engraving device to solve the problem in the prior art that when engraving a door panel, the engraving knife will give the door panel movement force, and the door panel cannot be tightly fixed only by two limit blocks.

In order to achieve the above object, the present invention provides the following technical solutions, the door panel engraving device includes a frame, the frame is provided with a workbench, a knife rest and a numerical control mechanism for controlling the movement of the knife rest, the knife rest is provided with a carving knife, and also includes a limiter. Position mechanism and dust collection mechanism. The limit mechanism includes a negative pressure cylinder fixed at the bottom of the workbench and a piston plate slidably connected in the negative pressure cylinder. A cuboid support plate is fixedly connected to the bottom of the piston plate in the negative pressure cylinder. The bottom of the piston plate is rotatably connected with a push rod, and the bottom of the push rod runs through the support plate, and the bottom of the push rod and the support plate form a thread pair; there are installation grooves on the workbench, and there are several installation grooves connected with the negative pressure cylinder. Through holes; the dust suction mechanism includes a piston barrel fixed on the frame and closed at both ends. A slide plate is slidably connected to the piston barrel. Both ends of the piston barrel are provided with an air inlet and an air outlet. Air one-way valve, the air outlet is equipped with an air outlet one-way valve and a filter screen; the air inlet is connected with an air inlet pipe, and the air outlet is connected with an air outlet pipe; the dust suction mechanism also includes a gear and a rack meshed with the gear. The rack is fixed on the tool holder, and the gear is rotatably connected to the workbench; it also includes first, second, and third support rods that are hinged in turn. The end of the first support rod away from the second support rod is fixed at the middle of the gear, and the One end of the three rods far away from the second rod is hinged with a first magnet block, the first magnet block is slidably connected to the side wall of the piston barrel, and a second magnet block which is attracted to the first magnet block is arranged on the slide plate.

The technical effect of the technical features of this scheme:

The limit mechanism is used to limit and fix the door panel to prevent the door panel from sliding during the engraving process, thereby avoiding the impact on the accuracy of the engraving. The dust suction mechanism is used to absorb the debris generated during the engraving process, so as to prevent the debris from affecting the accuracy of door panel engraving.

The installation slot is used to place the door panel to limit the door panel and prevent the door panel from shaking. The negative pressure cylinder, piston plate, push rod and worktable form a piston structure. When the push rod moves down, the piston moves down, and the gas at the bottom of the door panel and the installation groove is drawn out through the through hole to realize the adsorption of the door panel and fix the door panel on the Installed on the groove, so as to further prevent the door panel from moving and improve the accuracy of engraving. The support plate is in the shape of a cuboid, which can avoid the bottom seal of the negative pressure cylinder, and can realize the movement of the piston plate with the push rod; at the same time, the push rod and the support plate form a thread pair, and the movement of the piston plate can be realized by rotating the push rod. When the push rod stops After turning, the fixing of the piston plate can be realized. Therefore, when the piston plate is moved down to fix the door plate, the piston plate is stopped to be rotated, so that the door plate can be firmly fixed.

When the push rod drives the piston plate to move, the piston plate discharges the gas in the negative pressure cylinder upward through the through hole. When the door plate is being loaded, it can play a moving buffer role for the door plate, preventing the door plate from falling directly into the installation groove. In this way, the violent impact between the door panel and the installation groove can be avoided, resulting in damage to the door panel or the device. At the same time, when the door panel is taken out after the engraving is completed, the piston plate squeezes the gas in the negative pressure cylinder, and the gas blows the door panel upward through the through hole, so that the carved door panel can be taken out conveniently.

The movement of the slide plate can realize the pumping and deflation of the piston barrel on both sides of the piston. When the piston moves, one end of the piston barrel draws air through the air inlet, thereby sucking the debris generated by the carving into the piston barrel; while the other end of the piston barrel Air is blown through the air outlet, and when the door is engraved, grooves appear in the door, and the chips sit in the grooves. When absorbing dust, in order to avoid the upward force on the door panel due to the suction force of absorbing debris, the door panel will be moved up, so the air intake pipe will be arranged parallel to the upper surface of the door panel, but the parallel arrangement of the air intake pipe and the door panel will cause the debris in the groove to be difficult. was sucked out. The air outlet pipe is arranged perpendicular to the door panel, so that when the air is exhausted, the gas is blown to the surface of the door panel through the air outlet pipe, and the debris in the groove is blown out to facilitate the collection of debris. At the same time, the air outlet pipe is perpendicular to the door panel, so that when the air blowing pipe is discharged, the door panel is pressed downward, thereby providing a downward fixing force to the door panel to realize the fixing of the door panel.

When the knife rest moves, it drives the rack to move, and the rack moves to drive the gear to rotate. The first support rod, the second support rod, the third support rod and the first magnet block form a crank with the first support rod as a crank, the second support rod as a connecting rod, the third support rod and the first magnet block as a slider slider mechanism. According to the motion characteristics of the slider crank mechanism, the gear drives the first rod to rotate, so that the first magnet block slides along the side wall of the piston barrel, and the first magnet block attracts the second magnet block, thereby driving the second magnet block to slide, realizing Skateboard slides.

The technical principle of this program is:

Turn the push rod to drive the piston plate to move down, so that the negative pressure cylinder draws gas through the through hole, and absorbs the door panel in the installation groove to realize the fixing of the door panel. Then use the CNC mechanism to control the movement of the tool holder, and use the carving knife to carve the door panel. During the movement of the knife holder, the rack is driven to move, so that the gear rotates, thereby realizing the movement of the crank slider mechanism composed of the first pole, the second pole, the third pole and the first magnet block, so that the first magnet block drives the slide plate Move to realize the air intake and outlet of the piston barrel. When the air is inhaled, the debris generated by the engraving is sucked into the piston barrel. When the air is discharged, the debris in the groove generated by the engraving on the door panel is blown out, and the door panel is pressed down to make the door panel more tightly fixed.

The technical effects that this program can produce are:

1. Through the cooperation of the installation groove and the limit mechanism, this technical solution can make the door panel closely fit in the installation groove during the engraving process, which can avoid the movement of the door panel and improve the accuracy of engraving;

2. This technical solution can realize the suction and deflation of the piston barrel through the movement of the knife holder, so as to realize the cleaning of the debris generated by the carving;

3. This technical solution can blow out the debris in the groove produced after engraving through the air outlet pipe, so that it can be sucked into the piston barrel through the air inlet pipe for collection; at the same time, when the air outlet pipe is out of air, the door panel can be pressed down to make the door panel fixed in the mounting slot;

4. When the piston plate moves, the gas in the negative pressure cylinder can be discharged through the through hole, which can not only buffer the door panel when loading materials, but also blow the door panel upwards when unloading materials, giving the door panel an upward force. Easy to take out the door panel.
