Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a sheet metal processing device with negative pressure control. Background Technology

[0002] In the furniture industry, wood panel processing typically relies on metal tools to work on the surface of the panels. This process inevitably generates a large amount of heat and dust, which can easily lead to fires due to heat accumulation. To address this, existing panel processing equipment is equipped with negative pressure dust collection devices to remove dust generated during processing. However, in practice, if the negative pressure dust collection device malfunctions and stops operating, the dust cannot be removed in time, exacerbating heat accumulation and potentially causing a fire. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a negative pressure control plate processing device that can detect the operation of the negative pressure dust collection device in real time.

[0004] A negative pressure controlled sheet metal processing device includes a cutting head for cutting sheet metal, a negative pressure dust collection device that generates negative pressure to adsorb and clean the dust generated during sheet metal cutting, and a negative pressure detection device for detecting negative pressure on the negative pressure dust collection device.

[0005] Furthermore, the negative pressure detection device includes a detection connecting pipe that extends into the negative pressure dust collection device to detect the negative pressure within the device.

[0006] Furthermore, the negative pressure dust collection device specifically uses a dust collection pipe to generate negative pressure to adsorb dust. The dust collection pipe has a detection hole, and the detection connection pipe specifically passes through the detection hole and extends into the dust collection pipe to detect the negative pressure inside.

[0007] Furthermore, a controller for emergency shutdown of the cutter head is provided, and the controller is connected to a negative pressure detection device.

[0008] The sheet metal processing device of this utility model has a negative pressure dust collection device that generates negative pressure to adsorb and clean the dust generated during the cutting of sheet metal. The negative pressure dust collection device is equipped with a negative pressure detection device to detect the negative pressure status. The negative pressure detection device detects the actual negative pressure value inside the dust collection device to determine whether the dust collection device is operating normally. When the dust collection device malfunctions and stops operating, it can be detected in time to avoid dust accumulation leading to heat accumulation and fire. Attached Figure Description

[0013] The present invention will be further described in detail below with reference to specific embodiments.

[0014] Sheet metal processing equipment such as Figure 1 As shown, a support frame 51 is provided on the base 5, and the cutting head 1 is fixed on the support frame 51. When the board is placed on the base 5, it is cut by the cutting head 1, generating dust. A negative pressure dust collection device 2 is provided on the support frame 51 to generate negative pressure to adsorb and clean the dust generated during the cutting of the board.

[0015] like Figure 2 , Figure 3 As shown, the negative pressure dust collection device 2 specifically uses a dust collection pipe to generate negative pressure to adsorb dust. A detection hole 20 is opened on the side wall of the dust collection pipe. A negative pressure detection device 3 is installed on the negative pressure dust collection device 2, and it has a detection connecting pipe 30 that passes through the detection hole 20 on the side wall of the dust collection pipe and extends into the negative pressure dust collection device 2. In this state, the space inside the detection connecting pipe 30 is connected to the space inside the dust collection pipe, and the negative pressure conditions of the two are consistent. The negative pressure detection device 3 detects the negative pressure condition inside the detection connecting pipe 30 in real time, thereby indirectly detecting the negative pressure condition inside the dust collection pipe. The negative pressure detection device 3 detects the negative pressure condition inside the dust collection pipe through the detection connecting pipe 30 to prevent dust inside the dust collection pipe from damaging the negative pressure detection device 3 and affecting the detection results.

[0016] When the negative pressure dust collection device 2 is operating normally, the operator first uses the negative pressure detection device 3 to detect the standard negative pressure value generated by the negative pressure dust collection device 2 during normal operation. Then, the set negative pressure value of the negative pressure detection device 3 is set to be lower than this standard negative pressure value. The negative pressure detection device 3 is connected to a controller (not shown in the figure) to control the negative pressure of the board processing device. The cutter head 1 generates dust when cutting the board. If the negative pressure detection device 3 detects that the actual negative pressure value inside the negative pressure dust collection device 2 has not reached the set negative pressure value, it means that the negative pressure dust collection device 2 is not operating or has malfunctioned. The controller will then perform an emergency shutdown of the cutter head 1 to prevent the cutter head 1 from continuing to cut the board and generate dust while the negative pressure dust collection device 2 is malfunctioning, thus preventing a fire hazard.

[0017] In the second embodiment of the present invention described above, the negative pressure detection device 3 is connected to an alarm (not shown in the figure). When the blade 1 cuts the board, it generates dust. If the negative pressure detection device 3 detects that the actual negative pressure value inside the negative pressure dust collection device 2 has not reached the set negative pressure value, it means that the negative pressure dust collection device 2 is not operating or has malfunctioned. The device then sends an abnormal detection signal to the alarm, which alerts the operator to stop the blade 1. This prevents the blade 1 from continuing to cut the board and generate dust even when the negative pressure dust collection device 2 is malfunctioning, thus avoiding a fire hazard.
