Description

Technical Field

[0001] The utility model relates to an air knife component, in particular to an air knife component for diamond wire of a stone cutting machine applied in the field of stone cutting. Background Art

[0002] Currently, cutting machines are divided into single-wire cutting machines and multi-wire cutting machines. That is, single-wire cutting machines only have one diamond wire for cutting, while multi-wire cutting machines have multiple diamond wires for cutting at the same time. Single-wire cutting machines are suitable for occasions where materials are cut finely. Single-wire cutting machines have high cutting accuracy but low efficiency, while multi-wire cutting machines are suitable for occasions where materials are cut over a large area.

[0003] When cutting stone with a single-wire cutting machine, water is added to the cutting area in order to optimize the cutting process. The diamond wire enters the cutting chamber during rotation, causing water droplets on the surface of the diamond wire to fall into the cutting chamber, making the environment in the cutting chamber humid and with high water vapor. Over time, this may cause equipment failure or damage. Utility Model Content

[0004] In response to the above-mentioned existing technology, the technical problem to be solved by the present invention is that when using a wire cutting machine to cut stone, water droplets on the surface of the diamond wire will enter the cutting chamber when the diamond wire rotates, causing the environment in the cutting chamber to be humid and with high water vapor, which will cause damage to the equipment in the cutting chamber in the long run.

[0005] In order to solve the above problems, the utility model provides a wind knife assembly for diamond wire of a stone cutting machine, including a fixing box and a guide wheel fixedly installed in the fixing box, a wind blade unit is provided at the front end of the fixing box, the wind blade unit includes a positioning plate, a mounting plate is provided at the front end of the positioning plate, a plurality of screws are provided at the front end of the mounting plate, the rear ends of the screws are threaded through the mounting plate and the positioning plate in sequence, and the front ends of the positioning plate and the mounting plate are both provided with accommodating holes, the outer surface of the positioning plate is fixedly connected to two L-shaped mounting tubes, the outer surface of the guide wheel is coiled with a cutting wire, and the end of the cutting wire away from the guide wheel is movable through the fixing box and the accommodating hole in sequence, the end of the mounting tube away from the positioning plate is fixedly connected to an arc tube, and the corresponding ends of the two arc tubes are commonly fixedly connected to a three-way tube, the front end of the positioning plate is provided with an annular groove, the annular groove is communicated with the mounting tube, and the upper end of the fixing box is fixedly connected to a fixing lock.

[0006] In the wind knife assembly for diamond wire of the above-mentioned stone cutting machine, a wind blade assembly is set at the cutting chamber door. When the diamond wire rotates and enters the cutting chamber, the wind blade unit blows on the surface of the diamond wire to blow off the water droplets on the surface of the diamond wire, thereby effectively reducing the water droplets entering the cutting chamber through the diamond wire and effectively reducing the humidity in the cutting chamber.

[0007] As a further improvement of the present application, a plurality of screw rods are distributed in a circular array around the central axis of the mounting plate.

[0008] As a further improvement of the present application, the longitudinal section of the accommodating hole is conical, and the diameter of the inner wall of the accommodating hole at one end facing the fixing box is smaller than the diameter of the inner wall of the accommodating hole at one end away from the fixing box.

[0009] As a further improvement of the present application, the rear end of the positioning plate is fixedly connected to the front end of the fixing box, a gap is left between the positioning plate and the mounting plate, and the accommodating hole and the annular groove are connected through the gap.

[0010] As a further improvement and supplement to the present application, the gap is L-shaped, and the outlet of the L-shaped gap faces the small-diameter side of the accommodating hole.

[0011] As another improvement of the present application, two wind blade units are provided at the front end of the fixed box, and the corresponding ends of the two mounting tubes at the front are fixedly connected with auxiliary tubes, and an air supply tube is fixedly connected between the auxiliary tube and the three-way tube.

[0012] As another improved supplement of the present application, two L-shaped support rods are fixedly connected to the outer surface of the front positioning plate, and one end of the support rod away from the positioning plate is fixedly connected to the front end of the fixing box.

[0013] To sum up, in actual application, the fixing box is fixedly installed at the cutting chamber door. When the cutting line rotates, it moves through the guide wheel to pass through the wind blade unit, connecting the tee pipe to the external gas source. The gas enters the annular groove through the tee pipe, the arc pipe and the mounting pipe, so that high pressure is formed inside the annular groove. The gas then enters the accommodating hole through the gap between the positioning plate and the mounting plate, thereby blowing on the surface of the cutting line in the accommodating hole, blowing off most of the water droplets on the surface of the cutting line, thereby effectively reducing the water droplets entering the cutting chamber, and then effectively reducing the humidity in the cutting chamber, and extending the service life of the equipment in the cutting chamber.

[0022] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0023] The first implementation method:

[0024] Figure 1 and Figure 2 Shown is: a wind knife assembly for diamond wire of a stone cutting machine, including a fixed box 1 and a guide wheel 2 fixedly installed in the fixed box 1. The guide wheel 2 can change the direction of the cutting line 11 so that it rotates toward the wind blade unit. A wind blade unit is provided at the front end of the fixed box 1. The cutting line 11 is coiled on the outer surface of the guide wheel 2. The end of the cutting line 11 away from the guide wheel 2 moves through the fixed box 1 and the accommodating hole 6 in sequence. The upper end of the fixed box 1 is fixedly connected to a fixing lock 12.

[0025] Figure 3 、 Figure 4 and Figure 5The figure shows that the wind blade unit includes a positioning plate 3, a mounting plate 4 is provided at the front end of the positioning plate 3, and a plurality of screws 5 are provided at the front end of the mounting plate 4. The rear ends of the screws 5 are threadedly penetrated through the mounting plate 4 and the positioning plate 3 in sequence. The plurality of screws 5 are distributed in a circular array around the central axis of the mounting plate 4. The positioning plate 3 and the mounting plate 4 can be fixed by the screws 5, and the size of the gap between the positioning plate 3 and the mounting plate 4 can be adjusted. The front ends of the positioning plate 3 and the mounting plate 4 are both provided with accommodating holes 6. The longitudinal section of the accommodating holes 6 is conical, and the diameter of the inner wall of the accommodating holes 6 facing the end of the fixing box 1 is smaller than the diameter of the inner wall of the accommodating holes 6 away from the end of the fixing box 1. The cutting line 11 movably passes through the two accommodating holes 6, which is convenient for blowing on the surface of the cutting line 11. The outer surface of the positioning plate 3 is fixedly connected to two L-shaped mounting tubes 7, which is convenient for installing the arc tube 8. The mounting tube 7 is fixedly connected to an arc tube at one end away from the positioning plate 3. shaped tube 8, one end corresponding to the two arc tubes 8 is fixedly connected with a tee tube 9, which is convenient for connecting the two arc tubes 8 and the external air source. An annular groove 10 is cut at the front end of the positioning plate 3, and the annular groove 10 is communicated with the mounting tube 7 through a gap. The gap is L-shaped, and the outlet of the L-shaped gap is toward the small-diameter side of the accommodating hole 6. The gap can make the wind blade stick to the inner wall of the accommodating hole 6 and blow the wind blade toward the small-diameter side, so as to blow off the water droplets on the cutting line. The air source can enter the annular groove 10 after passing through the tee tube 9, the arc tube 8 and the mounting tube 7. The rear end of the positioning plate 3 is fixedly connected to the front end of the fixed box 1, and a gap is left between the positioning plate 3 and the mounting plate 4, and the accommodating hole 6 is communicated with the annular groove 10. After the gas enters the annular groove 10, air pressure is formed, and then it is discharged through the gap between the positioning plate 3 and the mounting plate 4, scraping off the water droplets on the surface of the cutting line 11, thereby drying the surface of the cutting line 11.

[0026] During use, the fixing box 1 is fixedly installed at the cutting chamber door. When the cutting line 11 rotates, it moves through the guide wheel 2 to pass through the wind blade unit, connecting the three-way pipe 9 to the external gas source. The gas enters the annular groove 10 through the three-way pipe 9, the arc tube 8 and the mounting tube 7, so that high pressure is formed inside the annular groove 10. The gas then enters the accommodating hole 6 through the gap between the positioning plate 3 and the mounting plate 4, thereby blowing on the surface of the cutting line 11 located in the accommodating hole 6, blowing off most of the water droplets on the surface of the cutting line 11, thereby effectively reducing the water droplets entering the cutting chamber, and then effectively reducing the humidity in the cutting chamber, thereby extending the service life of the equipment in the cutting chamber.

[0027] Second implementation method:

[0028] Based on the first embodiment, this embodiment adds a wind blade unit, an auxiliary pipe 13, an air pipe 14 and a support rod 15, and the rest of the parts are consistent with the first embodiment.

[0029] Figure 6It is shown that: two wind blade units are provided at the front end of the fixed box 1, and the corresponding ends of the two mounting tubes 7 located in the front are fixedly connected with an auxiliary tube 13. An air supply pipe 14 is fixedly connected between the auxiliary tube 13 and the three-way tube 9. The air supply pipe 14 can discharge the gas in the three-way tube 9 into the auxiliary tube 13, and then discharge it into the positioning plate 3 in the front through the auxiliary tube 13, thereby drying the cutting line 11 twice to improve the drying effect. Two L-shaped support rods 15 are fixedly connected to the outer surface of the positioning plate 3 located in the front, and the end of the support rod 15 away from the positioning plate 3 is fixedly connected to the front end of the fixed box 1.

[0030] When in use, the wind blade unit at the rear is the main wind blade unit, and the wind blade unit at the front is the auxiliary wind blade unit. The gas enters the auxiliary pipe 13 through the gas pipe 14, and then enters the front mounting pipe 7 and the annular groove 10 through the auxiliary pipe 13, thereby performing secondary drying on the cutting line 11, effectively improving the drying effect of the cutting line 11.

[0031] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
