Abstract
Description
Technical Field
[0001] The present application relates to a water blocking device, and particularly to a water blocking device for a cutting head of a cutting machine. Background Art
[0002] During the cutting process of hard and brittle materials such as silicon rods, it is necessary to cut the silicon rods through a cutting device and spray a coolant on the cutting position of the silicon rods. When technicians used the No. 1 cutting tool head of the Nissin nine-station cutting machine, they found that the phenomenon of coolant splashing often occurred during the spraying process of the coolant. These coolants will not only splash onto the ground and affect the site, but even splash onto the equipment control components and cause damage to the equipment control components. Therefore, it is necessary to surround the cutting tool head with a water blocking curtain to prevent the coolant from splashing.
[0003] However, the currently used ordinary water blocking curtain can only hang down naturally and cannot automatically rebound and straighten. When the coolant spray head descends, the ordinary water blocking curtain will no longer be tensioned after reaching the bottom limit. Therefore, a gap is easily formed between the bottom of the curtain body and the cutting head. The sprayed coolant will splash through the gap, making the water blocking curtain unable to fully and effectively block the splashing coolant. Moreover, after the spraying is completed, the ordinary water blocking curtain needs to be manually retracted and hung on the upper end of the cutting tool head, which is cumbersome and inconvenient to operate.

[0041] The embodiments of the present utility model will be described in detail below with reference to the drawings.
[0042] The embodiment of the present utility model provides a water blocking device for a cutting head of a cutting machine, as Figure 1 shown. The water blocking device includes a waterproof curtain assembly 1, a springback assembly 2, and an outer cover. The waterproof curtain assembly 1 includes a support rod 10, a waterproof curtain 11, and a pressing member 12. The waterproof curtain 11 is provided on the support rod 10, wound around the outer wall of the support rod 10 in a matching manner, and the pressing member 12 is movably installed at the winding end of the waterproof curtain 11. Both ends of the support rod 10 are respectively connected to the springback assembly 2. The springback assembly 2 generates an elastic force when the waterproof curtain 11 is unfolded. The counteraction between this elastic force and the gravity of the pressing member 12 keeps the waterproof curtain 11 in a continuous tension state without generating a shielding gap.
[0043] The waterproof curtain assembly 1, as Figure 2As shown in the figure, it includes a support rod 10, a waterproof curtain 11, and a pressing member 12. The waterproof curtain 11 is wound around the support rod 10 in a matching manner. That is, the length of the waterproof curtain 11 is equal to or slightly less than the length of the support rod 10. The pressing member 12 is movably installed at the winding end of the waterproof curtain 11. The pressing member 12 includes two magnet rods that attract each other with opposite polarities. Each magnet rod has an overall semi-cylindrical structure. The two magnet rods are attracted to the winding end of the waterproof curtain 11, and pulling the magnet rods can unfold the coiled waterproof curtain 11.
[0044] A resilience assembly 2, which is connected to the support rod 10. The resilience assembly 2 includes a bearing 20 and a spring coil 21, as Figure 3 or Figure 4 shown.
[0045] There are two bearings 20, which are respectively installed at both ends of the support rod 10. The bearing 20 is in rolling connection with the end of the support rod 10.
[0046] There are two spring coils 21. Each spring coil 21 is sleeved on the outer wall of the support rod 10 near the end. Among them, the inner end of each spring coil 21 is clamped to the side wall near one end of the support rod 10, and its outer end penetrates the side wall of the bearing 20. The spring coil 21 is a clockwork spring.
[0047] When the bearing 20 is stable and the pressing member 12 is pulled to unfold the waterproof curtain 11, the support rod 10 rotates clockwise. At this time, the elastic force of the spring coil 21 acts on the waterproof curtain 11 through the support rod 10 to continuously pull it back. When the gravity of the pressing member 12 is greater than the elastic force, the waterproof curtain 11 is in a continuously tensioned state. The pressing member 12 is removed from the waterproof curtain 11 and the waterproof curtain 11 is released. The waterproof curtain 11 automatically winds back around the outer wall of the support rod 10 due to the elastic force of the spring coil 21.
[0048] The outer cover includes a housing 3, a fixing column, and a fixing seat 33. The housing 3 is installed on the cutting head of the cutting machine through the connection of the fixing seat 33 on the cutting head of the cutting machine. The bearing 20 is fixed in the outer cover through the fixing column.
[0049] The housing 3 is provided with a bearing 20 that matches it. That is, the length of the housing 3 is greater than the distance between the two bearings 20, so that the support rod 10 is arranged parallel in the housing 3. The housing 3 includes a fixing plate and a movable plate. The movable plate is movably installed on the fixing plate.
[0050] The fixed plate is entirely composed of three long plates 31 of equal size. The two long side ends of one long plate 31 are respectively connected to the long side ends of a long plate 31. The outer end of the spring coil 21 penetrates through the side wall of the bearing 20 and is fixed to the inner side wall of the bottom of the fixed plate. A through hole matching the waterproof curtain 11 is opened at the bottom of the fixed plate. That is, the length of the through hole is equal to the length of the waterproof curtain 11, the width of the through hole is equal to or slightly larger than the thickness of the waterproof curtain 11, and a part of the wound waterproof curtain 11 protrudes out of the through hole of the housing 3, so that the waterproof curtain 11 can be conveniently pulled out from the through hole.
[0051] The movable plate is entirely composed of one long plate 31 and two short plates 32. The two short side ends of the long plate 31 are respectively connected to match with a short plate 32. The movable plate is arranged to match the fixed plate. That is, the long plate 31 of the movable plate and the long plate 31 of the fixed plate have the same size, and the length and width of the short plate 32 of the movable plate are slightly smaller than the width of the long plate 31 of the fixed plate. After the movable plate is clamped to the inner side wall of the fixed plate, the fixed plate and the movable plate are threadedly connected.
[0052] There are several fixing columns. The fixing columns are sequentially penetrated and installed on the short plate 32 of the movable plate and the bearing 20, so that the bearing 20 is fixed in the housing 3.
[0053] The fixed seat 33 is connected to the outer side wall of the movable plate. The fixed seat 33 is installed on the cutting head of the cutting machine. When the pressing member 12 is pulled to pull out the waterproof curtain 11 and hang it on the equipment cover below the cutting head, the above-mentioned waterproof curtain 11 surrounds the cutting head of the cutting machine. When the pressing member 12 is removed and the waterproof curtain 11 is released, the waterproof curtain 11 automatically shrinks back into the housing 3 due to the elastic force of the spring coil 21, and the operation is very convenient.
[0054] The installation method of the water blocking device of the present application is as follows:
[0055] Remove the movable plate, and a resilient component 2 is installed inside one end of the fixed plate: One end of the support rod 10 wound with the waterproof curtain 11 is rotatably connected to the bearing 20, and the inner end of the spring coil 21 is inserted into the outer wall of the near end of the support rod 20, and the outer end of the spring coil 21 penetrates through the side wall of the bearing 20 and is fixed to the inner side wall of the bottom of the fixed plate. The steps of installing another resilient component 2 at the other end of the fixed plate are the same as above.
[0056] After the movable plate is clamped to the inner side wall of the fixed plate, the fixed plate and the movable plate are threadedly connected. The fixing columns are sequentially penetrated and installed on the short plate 32 of the movable plate and the bearing 20.
[0057] Finally, the pressing member 12 is installed at the end of the wound waterproof curtain 11.
[0058] The specific working principle of the water blocking device of the present application is as follows:
[0059] When the cutting head performs a cutting operation, under the combined action of the spring coil 21 and the pressing member 12, while the waterproof curtain 11 is wound up as the cutting head descends, it can also remain in a tensioned state continuously without generating a shielding gap, avoiding the phenomenon that the sprayed water splashes outside through the gap to the equipment control components, which is likely to cause damage to the equipment control components. When it is necessary to wind up the waterproof curtain 11, after removing the pressing member 12 and directly loosening it, the waterproof curtain 11 automatically shrinks back into the housing 3 due to the elastic force of only the spring coil 21.
