Detailed Implementation

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0025] like Figs. 1-2 As shown, a preferred embodiment of the diaphragm cutting debris removal device of the present invention includes multiple debris suction hoods 3, a suction pipe assembly and a debris collection box 13.

[0026] The chip suction hood 3 is a structural component used to collect the chips generated during slitting. It is roughly plate-shaped, and multiple chip suction hoods 3 are arranged in a one-to-one correspondence with multiple cutters 2 mounted on the cutter shaft 1. The chip suction hood 3 has an airflow channel for accommodating the cutters 2. Under negative pressure, diaphragm chips can enter the airflow channel from the diaphragm slitting position. In this embodiment, a gap is left between the airflow channel and the cutter 2. The size of the gap can be designed according to the maximum size of the chips. It is understood that the smaller the gap, the faster the airflow velocity around the gap, the stronger the capture ability of small diaphragm chip particles, and the better the chip removal effect. As an example, the gap size between the airflow channel and the cutter 2 is 1-5 mm.

[0027] Considering the specifications of the end products, when product specifications are changed, the gap between two adjacent cutters 2 needs to be adjusted to cut the diaphragm into a specific width. Since the dust collection cover 3 is correspondingly positioned to the cutters 2, the position of the dust collection cover 3 also needs to be adjusted after the position of the cutters 2 is adjusted. Therefore, the device is equipped with a drive mechanism, which can move the dust collection cover 3 to the vicinity of the cutters 2. This embodiment does not specifically limit the structure of the drive mechanism. As an example, the drive mechanism includes an X-axis movement module and a Y-axis movement module.

[0028] The X-axis movement module is used to achieve linear motion along the X-axis. The X-axis movement module can be installed on the ground, for example, using existing tracks and track wheels. It can be arranged according to needs or the site structure. The X-axis movement module can also utilize existing equipment, such as combinations of tracks and track wheels, gear racks, gear chains, guide rods, and sliders. The X-axis movement module also includes a support base 6, which can move along the X-axis. The support base 6 can be used as a mounting base for components, and its structure can be configured as needed.

[0029] The Y-axis moving module is used to realize the movement in the Y-axis direction. The Y-axis moving module is connected to the support base 6, so that the support base 6 can drive the Y-axis moving module to move in the X-axis direction, to realize the position change of the Y-axis moving module in the X-axis direction. The Y-axis moving module can also adopt the existing track and track wheel, gear rack, gear chain, guide rod and slider combination structure and other existing devices.

[0030] As an example, the X-axis moving module is connected to the rack (not shown), the Y-axis moving module is arranged at the moving end of the X-axis moving module, and the dust cover 3 is arranged at the moving end of the Y-axis moving module through the mounting piece 4, that is, the X-axis moving module, the Y-axis moving module and the dust cover 3 are connected in series, so that the dust cover 3 can be used through the cooperation of the X-axis moving module and the Y-axis moving module to realize the movement in the X-axis and Y-axis directions.

[0031] In this embodiment, the structures of the X-axis moving module and the Y-axis moving module can be the same, and both include linear guides. In order to facilitate the distinction, the two linear guides are defined as X-axis linear guide and Y-axis linear guide 5 respectively. The X-axis linear guide extends in the horizontal direction, and the Y-axis linear guide 5 extends in the vertical direction. The support base 6 is slidably connected to the X-axis linear guide, and the support base 6 is provided with a sliding groove. The Y-axis linear guide 5 is embedded in the sliding groove. The dust cover 3 is fixedly arranged on the Y-axis linear guide 5. The support base 6 and the X-axis linear guide and the Y-axis linear guide 5 can be fixed by the locking bolt 7. In this way, the cooperation of the support base 6 and the X-axis linear guide can drive the dust cover 3 to move in the horizontal direction, and the cooperation of the support base 6 and the Y-axis linear guide 5 can drive the dust cover 3 to move in the vertical direction, so that the dust cover 3 can be moved to the vicinity of the cutter 2.

[0032] The air suction pipe assembly includes the air suction main pipe 10 and a plurality of air suction branch pipes 8. In order to simplify the structure of the device, the X-axis linear guide can be designed as a pipe structure, that is, the support base 6 is slidably connected to the air suction main pipe 10, and the support base 6 and the air suction main pipe 10 are locked by the locking bolt 7. The dust cover 3 and the air suction main pipe 10 are communicated through the air suction branch pipe 8. The air suction branch pipe 8 adopts a flexible pipe structure to ensure that the dust cover 3 and the air suction main pipe 10 remain in a communication state. In the air suction branch pipe 8, the air containing the debris can flow from the side of the dust cover 3 to the side of the air suction main pipe 10.

[0033] The dust collecting box 13 is a dust collecting box 13 for collecting and storing the dust, and the dust collecting box 13 can be made of a transparent material for the convenience of observing the collection of the dust. The dust collecting box 13 is communicated with the air suction main pipeline 10 through the air pipe 12, and in the air pipe 12, the air containing the dust flows from the air suction main pipeline 10 side to the dust collecting box 13 side. The dust collecting box 13 is also connected with the vacuum suction pipe 11 and the vacuum suction device 9, and the differential pressure can be formed in the dust collecting box 13 by the vacuum suction device 9, so that the diaphragm dust in the dust suction cover 3 can smoothly enter the dust collecting box 13 through the air pipe 12. In the embodiment, the length of the vacuum suction pipe 11 extending into the dust collecting box 13 is 100-140mm shorter than the length of the air pipe 12 extending into the dust collecting box 13, which can reduce the possibility of the diaphragm dust particles being sucked into the vacuum suction pipe and reduce the risk of the diaphragm dust and particles polluting the vacuum suction pipe.

[0034] The working principle of the diaphragm cutting dust suction device in the embodiment will be described below.

[0035] According to the width of the cutting diaphragm, the position of the dust suction cover 3 is adjusted by the driving device, so that the dust suction cover 3 covers the cutter 2. When the diaphragm is cut, the vacuum suction device 9 is started, and under the action of the vacuum suction, the dust and particles generated during the cutting of the diaphragm enter the dust suction cover 3 along the periphery of the cutting position of the diaphragm, and then enter the dust collecting box 13 through the air suction pipe assembly. When the dust collecting box 13 is filled with diaphragm dust, the maintenance personnel need to clean the dust collecting box 13 regularly to keep the pipeline unobstructed.

[0036] In summary, the diaphragm cutting dust suction device has a compact structure design, and the micron-level dust generated during the cutting process is sucked and removed in real time by the vacuum negative pressure air duct, which effectively solves the problem of residual dust during the cutting of the diaphragm, and helps to improve the product yield and quality.

[0037] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model.
