Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical technology, and in particular to a vacuum adsorption partitioned reverse suction box. Background Technology
[0002] The processing of sheet materials usually involves a cutting step, which is generally done by a cutting machine. The cutting machine has a large working surface on which the sheet material is placed and cut. During this process, the sheet material needs to be positioned.
[0003] In existing technologies, the material is usually fixed by clamping the edge or center point, and some are fixed by magnetic attraction. However, clamping means that part of the material cannot be processed, which may cause some material waste. Magnetic attraction, on the other hand, may not completely dissipate after processing, making it difficult to remove the material.
[0004] Therefore, a new method is needed to solve the above problems. Utility Model Content
[0005] In order to solve the above problems, this utility model provides a vacuum adsorption partitioned reverse suction box.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a vacuum adsorption partitioned reverse suction box, including a frame and worktables and vacuum adsorption devices respectively arranged on both sides of the frame. The vacuum adsorption device includes a vacuum pump and a gas pipe. The worktable is composed of multiple adsorption zones, and the gas pipe is connected to the adsorption zones.
[0007] By adopting the above settings: when the vacuum pump is started, the air pipe can evacuate the worktable surface, thereby using the vacuum to adsorb the board onto the worktable surface, thus ensuring that the board will not move during processing. In addition, the vacuum pump can also be set to backflush. After processing, the vacuum between the board and the worktable surface can be released by blowing air, so that the board can be easily removed. Multiple adsorption zones can adsorb different parts of the worktable surface. When the board is small and can only occupy a part of the zone, or when the board has different fixation requirements for different parts, it can avoid targeted adsorption of that part.
[0008] Furthermore, a connecting part is fixedly connected below the adsorption zone, the connecting part is hollow to form a negative pressure cavity, and a connecting pipe for connecting to the trachea is provided on the connecting part so that the trachea is connected to the negative pressure cavity.
[0009] By adopting the above settings, a certain vacuum area can be formed under the worktable, thereby ensuring that the adsorption area has sufficient adsorption capacity.
[0010] Furthermore, the vacuum adsorption device also includes a flow divider box, one end of which is connected to the vacuum pump. The flow divider box is equipped with a partition plate and forms an airflow channel and airflow partition inside it. Each airflow partition is equipped with a solenoid valve at the connection between it and the airflow channel.
[0011] By adopting the above settings, the solenoid valve is used to control the opening and closing of the airflow channel and the airflow zone, thereby controlling the gas flow in the air pipe, and thus achieving the effect of zonal control by inhaling or blowing air into a specific adsorption area.
[0012] Furthermore, a sensing module is provided on the adsorption area, and the sensing module is connected to the solenoid valve through a control center.
[0013] By adopting the above settings, the sensing module can send signals to the control center based on the actual situation on the workbench, and then the control center can control the opening and closing of the solenoid valve.
[0014] Furthermore, the vacuum pump is a liquid ring vacuum pump.
[0015] By adopting the above settings, the liquid ring vacuum pump has the advantages of low mechanical failure rate, convenient maintenance, quiet operation, and low vibration. It can reduce the vibration generated by the cutting machine itself when the vacuum pump is running, thereby ensuring that the cutting machine can work normally. At the same time, it can also improve the reliability of the equipment and reduce maintenance costs.
[0016] Compared with the prior art, the advantages of this utility model are:
[0017] By utilizing a vacuum pump and adsorption zone, a vacuum area is created on the worktable, thereby adsorbing the board onto the worktable to replace the original clamp fixation. Since the fixation method is through bottom adsorption, it avoids the impact of the fixation method on the surface processing. Furthermore, by setting up airflow channels and airflow zones controlled by solenoid valves, different airflow zones can affect different air pipes, thereby affecting different adsorption zones. This allows different parts of the worktable to be adsorbed or back-blown individually, enabling the worktable to fix boards of different sizes. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] like Figures 1 to 3 As shown, the vacuum adsorption partitioned back suction box includes a frame 1, a worktable 2 and a vacuum adsorption device 3 respectively disposed on both sides of the frame 1. The vacuum adsorption device 3 includes a vacuum pump 31 and an air pipe 32. The worktable 2 is composed of multiple adsorption zones, and the air pipe 32 is connected to the adsorption zones. When the vacuum pump 31 is started, the air pipe 32 can draw a vacuum on the worktable 2, thereby using the vacuum to adsorb the board onto the worktable 2, thus ensuring that the board will not move during processing. The vacuum pump 31 can also be set to back-blowing. After processing, the vacuum state between the board and the worktable 2 is released by blowing air, so that the board can be easily removed. The multiple adsorption zones can adsorb different parts of the worktable 2. When the board is small and can only occupy part of the zone, or when the board has different fixation requirements for different parts, it can avoid targeted adsorption of that part.
[0025] like Figure 3 As shown, a connecting part 21 is fixedly connected to the lower part of the adsorption zone. The connecting part 21 is hollow to form a negative pressure chamber. A connecting pipe is provided on the connecting part 21 for connecting to the air pipe 32 so that the air pipe 32 is connected to the negative pressure chamber. The negative pressure chamber can form a certain vacuum area under the workbench 2, thereby ensuring that the adsorption zone has sufficient adsorption capacity.
[0026] like Figure 3 and Figure 4As shown, the vacuum adsorption device 3 also includes a flow divider 33. One end of the flow divider 33 is connected to the vacuum pump 31. A partition plate 34 is provided inside the flow divider 33, forming an airflow channel 35 and an airflow partition 36. Each airflow partition 36 is equipped with a solenoid valve at the connection between it and the airflow channel 35. The solenoid valve is used to control the opening and closing of the airflow channel 35 and the airflow partition 36, thereby controlling the gas flow in the air pipe 32, and thus achieving the effect of zonal control by sucking or blowing air into a specific adsorption area. A sensing module is provided on the adsorption area. The sensing module is connected to the solenoid valve through the control center. The sensing module can send a signal to the control center according to the actual situation on the workbench 2, and then the control center controls the opening and closing of the solenoid valve. The vacuum pump 31 is a liquid ring vacuum pump 31. The liquid ring vacuum pump 31 has the advantages of low mechanical failure rate, convenient maintenance, quiet operation, and low vibration. It can reduce the vibration generated by the cutting machine itself when the vacuum pump 31 is running, thereby ensuring that the cutting machine can work normally. At the same time, it can also improve the reliability of the equipment and reduce maintenance costs.
