Description

Technical Field

[0001] The utility model relates to the technical field of graphite band sawing machine equipment, in particular to a high-efficiency dust suction structure of a vertical graphite sawing machine. Background Art

[0002] At present, the manufacturing of vertical graphite band saws is mostly extended from the conversion of metal cutting saws. The cutting parameters and performance of graphite band saws have been studied thoroughly, but the collection of graphite chip powder needs further exploration. Existing graphite cutting is mostly done by dry cutting, and dust is generally collected through 2-3 chip suction ports. The dust enters the dust collection system through the pipeline from the chip suction port.

[0003] However, the dust collection effect of this dust collection system is poor, especially in the lower guide and lower wheel cavity, which is very easy to cause chip accumulation and dust overflow, affecting the on-site working environment. In addition, due to the conductivity of graphite itself, graphite powder falls on electrical components, which can easily cause equipment short circuit failure and burn out of electrical components. Utility Model Content

[0004] The utility model aims to provide a vertical graphite sawing machine with an efficient dust suction structure, which greatly improves the dust suction effect by arranging a dust suction air duct along the rotation direction of the saw belt, and solves the problems of graphite powder overflow or local concentrated accumulation in the prior art.

[0005] To achieve the above purpose, the utility model provides a vertical graphite sawing machine with high efficiency dust collection structure, comprising:

[0006] The inner wheel air duct ring is arranged inside the saw belt wheel in the wheel cavity under the base and is directly connected to the base;

[0007] The outer wheel air duct ring is vertically arranged on the outer protective door of the base and is arranged corresponding to the outer side of the saw belt wheel in the lower wheel cavity;

[0008] The under-wheel air duct ring is arranged below the saw belt wheel in the under-wheel cavity of the base and is directly connected to the base;

[0009] The air duct outlet pipe is located on the base and is correspondingly connected to the end of the outer wheel air duct ring.

[0010] Furthermore, an inner baffle is provided on the inner side of the lower guide of the saw belt on the base, and an outer baffle is provided on one side of the base. The inner baffle, the outer baffle, the protective plate and the base form a funnel shape.

[0011] Furthermore, a dust shield corresponding to the saw band wheel is provided above the inlet end of the air duct outlet pipe.

[0012] Furthermore, the distance between the inner air duct ring and the saw belt wheel, and the distance between the outer air duct ring and the saw belt wheel are both 2.5 mm.

[0013] Furthermore, a chip suction port is provided at the cutting position of the saw belt above the base, and the chip suction port is connected to the dust collection device through a pipeline.

[0014] Since graphite powder moves along the direction of the saw belt discharge, the lower guide of the vertical graphite sawing machine is the part where the dust is most concentrated, accounting for about 80% to 90% of the cutting dust of the vertical graphite sawing machine. The utility model adds a dust suction air duct in the lower wheel cavity to lead out this part of the graphite dust and directly connect it to the dust collection device. Combined with the dust suction of other parts, the overall dust suction effect is greatly improved.

[0015] The dust suction structure of the utility model forms a nearly funnel-shaped structure through a plurality of accessories at the guide part under the saw band, including a base, an inner baffle plate, an outer baffle plate and a protective door, so that graphite powder after cutting by the saw band can be discharged downward in a centralized manner.

[0016] Along the direction of rotation of the saw band wheel, a semi-circular air duct is formed through the inner wheel air duct ring on the inner side of the wheel edge, the outer wheel air duct ring on the outer side, and the lower wheel air duct ring at the bottom, so that the graphite dust can be discharged smoothly and does not fly around in the entire lower wheel cavity. The inner wheel air duct ring and the lower wheel air duct ring are directly welded to the base, and the outer wheel air duct ring is fixed to the protective door with screws and can be opened and closed together with the aluminum alloy protective door. The inner wheel air duct ring, the outer wheel air duct ring and the saw band wheel edge are guaranteed to have a 2.5mm gap, which does not interfere with the rotation of the saw band wheel.

[0017] The dust shield welded on the left side of the semi-circular air duct can effectively block the path of dust running along the saw belt. At the same time, the powder directly enters the air duct outlet pipe in the semi-circular air duct obliquely upward to lead the graphite dust out and connect it to the dust collection device for centralized treatment.

[0018] The dust collection device and its blower structure in the base enhance the stability of the overall equipment and ensure its stable operation. In addition, the protective door and the base structure are separate structures for easy operation. BRIEF DESCRIPTION OF THE DRAWINGS

Similar elements in different embodiments are usually marked with similar numbers.

[0030] like Figure 1 As shown, a high-efficiency dust suction structure of a vertical graphite sawing machine includes a base 1, an upper wheel cavity and a lower wheel cavity are provided on the base 1, and the saw band rotates on the saw band wheels of the upper wheel cavity and the lower wheel cavity to achieve graphite cutting. A semi-annular air duct is provided in the lower wheel cavity of the base 1, and the semi-annular air duct includes an inner wheel air duct ring 2 located on the inner side of the saw band wheel 6, an outer wheel air duct ring 3 arranged on the outer side of the saw band wheel 6, and an under-wheel air duct ring 4 arranged below the saw band wheel. The air duct formed by the inner wheel air duct ring 2, the outer wheel air duct ring 3 and the under-wheel air duct ring 4 can achieve smooth discharge of powder.

[0031] In this embodiment, the inner wheel air duct ring 2 is arranged inside the saw belt wheel 6 in the lower wheel cavity of the base 1 and is directly welded to the base 1. The lower wheel air duct ring 4 is arranged below the saw belt wheel 6 in the lower wheel cavity of the base 1 and is directly welded to the base 1. The outer wheel air duct ring 3 is vertically arranged on the outer protective door 5 of the base 1 and is arranged corresponding to the outer side of the saw belt wheel in the lower wheel cavity. The spacing between the inner wheel air duct ring 2 and the saw belt wheel 6 and between the outer wheel air duct ring 3 and the saw belt wheel 6 is 2.5 mm, which ensures the stable operation of the saw belt wheel 6.

[0032] An inner baffle 8 is provided on the inner side of the lower guide of the saw belt on the base 1, and an outer baffle 9 is provided on one side of the base 1. The inner baffle 8, the outer baffle 9, the protective plate 5 and the base 1 form a funnel shape to limit the flow direction of the graphite powder and prevent the powder from flying around.

[0033] On the base 1, an air duct outlet pipe 7 is connected to the end of the semi-circular air duct, and the powder in the semi-circular air duct is discharged from the air duct outlet pipe 7. A dust shield 10 corresponding to the saw band wheel 6 is provided above the inlet end of the air duct outlet pipe 7, and the dust shield 10 can prevent the powder from moving with the saw band wheel 6. The powder entering the air duct outlet pipe 7 is processed by the dust collection device.

[0035] Operation mechanism: When the equipment is running, as the saw band wheel 6 rotates, the powder moves with the saw band from the lower guide. Then, at the funnel-shaped structure, the powder flows to the semi-annular air duct. Under the action of the inner air duct ring 2, the outer air duct ring 3 and the lower air duct ring 4 of the semi-annular air duct, the powder enters the dust collection device for centralized processing.
