Description

Technical Field

[0001] The invention belongs to the technical field of plate pattern processing, and in particular relates to a plate pressing device and a pressing method. Background Art

[0002] In the panel furniture industry, veneer processing is an indispensable link, which can provide the market with a variety of color and appearance options. However, in the process of veneer processing, the entire industry will be affected by the differences in processing appearance quality caused by different veneer equipment. In particular, the most difficult to control in the process is the characteristics of paper laying and press operation, which lead to uncontrollable factors in the environment such as dust and sawdust being brought into the equipment by airflow, resulting in the misalignment of the paper surface and the substrate due to airflow, carbonized black spots on the surface, sawdust on the surface, and other quality appearance defects when processing panels. At present, most of the equipment on the market is divided into domestic single-line machines and imported connecting machines, but all similar equipment relies on a slider to lift up and down to complete the veneer processing. As long as there is a slider lifting up and down, the airflow around the machine will change, which will cause the debris in the air environment (ash layer, sawdust, etc.) to be uncontrollably sucked into the machine, affecting the surface quality after the sticker is pasted. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings, the inventor of the present invention has continuously reformed and innovated through long-term exploration and attempts, multiple experiments and efforts, and proposed a plate pressing device and pressing method, which solves the problem of surface quality defects in the process of processing veneer patterns on plates. At the same time, it can also automatically handle the difficulties in the operation process of such equipment, avoid the airflow generated by the upper and lower sliders of the pressing equipment when they are separated from each other to bring dust into the equipment and the machine, and solve the problem of the airflow in the air environment generated by the rapid movement of the board inlet and outlet trolleys during operation to bring dust and sawdust into the machine, and solve the problem of paper displacement caused by the air being poured into the surface of the substrate when the board inlet trolley moves quickly to unload the board during paper laying operation. This significantly improves process defects and improves efficiency and quality.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: to provide a plate pressing device, which includes a pressing device, a dust blowing device, a dust suction device, and a high-frequency electrostatic gun. The air blowing port of the dust blowing device is located between the pressing device and the plate feeding trolley and is arranged toward the substrate support plate to blow toward the surface of the substrate. The dust suction device includes a dust suction device and a brush. The brush contacts the belt of the plate feeding trolley for brushing dust. The dust suction device is arranged near the contact position between the belt of the plate feeding trolley and the brush to cooperate with dust suction. The dust suction device discharges the airflow through the exhaust pipe to the two sides of the plate discharge trolley at the rear end of the press. When the plate discharge trolley takes out the plate that has been bonded in the pressing device, the airflow discharged from the exhaust pipes at both ends will blow away the dust on the surface of the plate discharge trolley. A high-frequency electrostatic gun is arranged on the side of the plate feeding trolley.

[0005] According to the plate pressing device described in the present invention, a further preferred technical solution is: the dust blowing device uses a flat air blowing port to form an air knife, and the air knife blows downwardly toward the surface of the substrate.

[0006] According to the board pressing device described in the present invention, a further preferred technical solution is that the air blowing port is 5-8 cm away from the edge of the substrate, has a height of 5-10 cm, and an inclination angle of 15°.

[0007] According to the plate pressing device described in the present invention, a further preferred technical solution is that the air knife coverage area is greater than or equal to the substrate width.

[0009] According to the sheet pressing device described in the present invention, a further preferred technical solution is: there are two dust pumps, both connected to the dust box and arranged symmetrically on both sides, and the outlets of the two dust pumps extend to the two sides of the sheet discharge trolley through pipes respectively.

[0010] A plate pressing method, the steps of which include: The substrate support plate rises to lift the substrate to the predetermined position, the dust blowing device continues to operate, and the air knife removes dust from the surface of the substrate; The suction cup absorbs and lifts the substrate, and the air knife blows the gap between the substrate and the next substrate to remove dust from the bottom surface of the substrate; The dust suction device is running continuously, using a brush to brush off the dust and wood chips on the surface of the board feeding trolley.

[0018] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. Therefore, the detailed description of the embodiments of the present invention provided below is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention.

[0019] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in the subsequent drawings.

[0020] Embodiment 1: like Figure 1 As shown, a plate pressing device comprises a pressing device 1, a dust blowing device 2, a dust collecting device 3, and a high-frequency electrostatic gun 4. The air blowing port 201 of the dust blowing device 2 is located between the pressing device 1 and the plate feeding trolley 7 and is arranged toward the substrate support plate 5 to blow toward the surface of the substrate. The dust collecting device 3 comprises a dust collecting device 301 and a brush 302. The brush 302 contacts the belt of the plate feeding trolley 7 for brushing dust. The dust collecting device 301 is arranged near the contact position between the belt of the plate feeding trolley 7 and the brush 302 to cooperate with dust collection. The dust collecting device 301 discharges the air flow through the exhaust pipe 304 to the two sides of the plate discharging trolley 8 at the rear end of the press. The end of the exhaust pipe 304 is stationary relative to the ground. It is to utilize the plate discharging trolley 8 to discharge the air. The movement of the car 8 realizes dust blowing of the whole car. The side can correspond to the position of the plate-out trolley 8 or the position where the plate-out trolley 8 will pass. However, it should be noted that the whole area of ​​the plate-out trolley 8 needs to be dust-blown. Therefore, it is necessary to be in the place where the front and rear ends of the plate-out trolley 8 will pass. When the plate-out trolley 8 takes out the plate that has been bonded in the pressing device 1, the exhaust pipe 304 at both ends discharges the airflow to blow away the dust on the surface of the plate-out trolley 8 before receiving it. After receiving it, it can also be dusted and cooled again. A high-frequency electrostatic gun is set on the side of the plate-in trolley 7. The high-frequency electrostatic gun is manually operated, so it is only necessary to set the high-frequency electrostatic gun 4 near the plate-in trolley 7. In addition, the equipment in the present invention is relatively mature. It is only for simplified drawing here, and the external equipment is omitted, such as the front-end compressed gas and filtered gas equipment connected to the blowing port 201, such as the external slide rail system of the plate-in trolley 7 and the plate-out trolley 8, etc. For the pressing device 1, only the upper and lower pressing plates are shown, and the external heating and pressing devices are not drawn.

[0021] The dust blowing device 2 uses a flat air outlet 201 to form a wind knife, which is tilted downward to blow toward the surface of the substrate 9. The strength and angle of the wind knife can be adjusted according to actual needs. The air outlet 201 is 5-8 cm away from the edge of the substrate, 5-10 cm high, and has an inclination angle of 15°. Of course, the distance can also be adjusted. The wind knife covers an area greater than or equal to the width of the substrate, which is convenient for complete and comprehensive cleaning of the substrate surface.

[0022] The dust collection device 301 includes a dust collection pump and a tool box 303. The dust collection pump is connected to the tool box 303. The tool box 303 is of the same width as the belt of the board-feeding trolley 7 and is arranged in parallel. A brush 302 is installed on the tool box 303. The length of the brush 302 is greater than or equal to the belt width, and the belt is fully cleaned. The belt is arranged on the surface of the board-feeding trolley 7. After the substrate is attached to the face paper, it is placed on the belt as a whole. The rotation of the belt is used to match the movement of the board-feeding trolley 7 to send the substrate into the pressing device 1. There are two dust collection pumps, which are connected to the dust collection box and arranged symmetrically on both sides. The outlets of the two dust collection pumps extend to the two sides of the board-feeding trolley 8 through pipes, respectively, for dust removal of the board-feeding trolley 8.

[0023] Embodiment 2: like Figure 2 As shown, a plate pressing method comprises the following steps: The substrate support plate 5 rises to lift the substrate to a predetermined position, the dust blowing device 2 continues to operate, and the wind knife removes dust from the surface of the substrate. The substrates are stacked on the substrate support plate 5, and the substrate is raised each time a substrate is taken so that the top layer is basically convenient to take; The suction cup 6 absorbs and lifts the substrate 9, and the air knife blows the gap between the substrate and the next substrate to remove dust from the bottom surface of the substrate. At this time, when the suction cup 6 absorbs and lifts the substrate 9, it stays at a preset height for 2 seconds to facilitate the blowing of dust from the bottom surface of the substrate. Of course, the stay time and height can be set according to actual needs. At the same time, since the blowing position of the air knife is relatively fixed, the blowing port 201 can be set to a form that can change the position of the air knife, such as a rotatable blowing port 201 or a movable blowing port 201, etc.; At the same time, the dust collecting device 3 continues to operate, using the brush 302 to brush off the dust and wood chips on the surface of the board feeding trolley 7, and the dust collecting device 301 absorbs the dust and wood chips brushed off, while maintaining the exhaust pipe 304 to exhaust air, that is, a continuous dust collection effect is formed to form protection; The operator lays the bottom surface paper on the belt of the board feeding trolley 7 which stops running at the initial position. At this time, the board feeding trolley 7 stops running, and the previous rotation of the belt makes the belt located on the upper side a clean belt that has been brushed by the brush 302, ensuring that the bottom surface paper is laid on a dust-free belt to avoid bulges caused by black spots and wood chips on the bottom surface during pressing; The suction cup 6 is operated to place the dust-removed substrate on the bottom surface paper. Here, the substrate is positioned by an infrared right-angle frame when placed on the bottom surface paper. The infrared frame is used as a positioning reference when laying paper. Of course, this is only a more convenient positioning method, and other similar positioning methods can also be used; The operator places the surface paper on the surface of the substrate, and uses a high-frequency electrostatic gun to blow the surface paper to make it adsorb on the substrate, so that when the substrate is transferred from the board feeding trolley 7 to the inside of the pressing device 1, the surface paper is also attached to the substrate without wrinkles and displacement, ensuring the stability of the position of the pattern; The board feeding trolley 7 runs, and the substrate and the sticker are fed into the pressing device 1 for pressing to form a board. The pressing device 1 is relatively mature, and the equipment and process to achieve this function will not be described in detail here; After the pressing is completed, the plate discharging trolley 8 moves toward the pressing device 1, and the exhaust duct 304 removes dust from the moving plate discharging trolley 8. After receiving the plate, the plate discharging trolley 8 returns, and the exhaust duct 304 cools it. Dust removal again can ensure that the processed plates will not be damaged or scratched by friction caused by dust after being stacked.

[0024] During the whole process, the movement sequence of the substrate is that the top substrate on the substrate support plate 5 is transferred by the suction cup 6 to the board feeding trolley 7, and the two sides are covered with facial paper on the board feeding trolley 7 (the bottom is mainly pressed, and the surface is electrostatically adsorbed), and then the board feeding trolley 7 uses a belt to transfer the substrate covered with facial paper as a whole to the pressing device 1 for pressing, and after completion, the board unloading trolley 8 unloads the board.
