DETAILED DESCRIPTION

[0036] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, they can also be understood as further technical solutions without paying creative work. In some figures, components with the same structure or function are only schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0037] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0038] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, proposes a foldable dust collecting hood, including: a collecting bucket 1 has a collecting groove 110, and the collecting groove 110 is located at the top of the collecting bucket 1; a support frame 2 is rotatably set on the collecting bucket 1, and after the support frame 2 rotates, the support frame 2 is opened or retracted; a dust collecting plate 3 is detachably set on the support frame 2, and the support frame 2 is used to support the dust collecting plate 3 after it is opened.

[0039] In this embodiment, the collecting bucket 1 is used to collect flying sparks and iron filings generated after cold sawing, ensuring that the iron filings generated during the sawing process can enter the collecting tank 110 and will not fall to the ground. The support frame 2 is used to support the dust collecting plate 3 to ensure that the dust collecting plate 3 can collect small dust after it is unfolded. When the dust collecting plate 3 is folded and removed from the support frame 2, the dust collecting plate 3 can be placed in the mobile phone slot as a slot cover of the collecting tank 110, which not only reduces the overall volume, but also is more convenient when unfolded. When the dust collecting hood is not in use, a large amount of dust will not fall into the collecting tank 110, which reduces the time for cleaning the collecting bucket 1 and simplifies the steps of using the dust collecting hood. After the dust collecting hood is folded, the volume is only the size of the collecting bucket 1, which is not only convenient for placement, but also easy to move and carry. The walking wheel 5 is installed on the collecting bucket 1. When the collecting bucket 1 is folded and needs to be moved, it can be moved by the walking wheel 5, making the movement of the collecting bucket 1 more convenient and reducing the burden of movement.

[0040] As a further technical solution, the dust collecting plate 3 includes: a first plate body 310 and a second plate body 320, each of the first plate body 310 and the second plate body 320 has a plurality of hinges, one end of the two first plate bodies 310 are hinged to each other, and the end of the first plate body 310 that is not hinged to the adjacent first plate body 310 is hinged to the second plate body 320; there are a plurality of hinges 330, which are respectively arranged at the connection between the two first plate bodies 310 and the connection between the first plate body 310 and the second plate body 320.

[0041] In this embodiment, the dust collecting plate 3 is composed of a first plate body 310 and a second plate body 320. Multiple dust collecting plates 3 can be combined into a variety of different shapes and connected by hinges 330. This not only facilitates the folding and unfolding of the first plate body 310 and the second plate body 320, but also allows the unfolded shape of the dust collecting plate 3 to be adjusted more quickly, thereby facilitating adaptation to different types of cut parts and improving the adaptability of the device.

[0042] As a further technical solution, the first plate body 310 and the second plate body 320 both have a dust suction space 340 and a dust suction port 350, the dust suction port 350 is connected to the dust suction space 340, and also includes: a filter screen 360 is arranged in the dust suction space 340, the filter screen 360 has a plurality of filter holes, and the filter screen 360 is used to filter the dust entering the dust suction space 340.

[0043] In this embodiment, the first plate 310 and the second plate 320 both have a dust suction space 340 for sucking dust near the first plate 310 and the second plate 320 to ensure that the smaller dust that flies up can be collected uniformly to prevent dust from flying around and affecting the health of workers. The dust suction space 340 is divided by a filter 360, and one side has a dust suction port 350. The dust suction port 350 allows dust and other particles to enter the dust suction space 340 and contact the filter 360 to ensure that the filter 360 can filter dust normally and prevent dust from flying around. The filter 360 can achieve different filtering effects through different filter hole sizes, thereby ensuring different filtering effects of the device facing different dusts.

[0044] As a further technical solution, the first plate body 310 is provided with an air extraction hole 380 , and the air extraction hole 380 is connected to the dust suction space 340 .

[0045] In this embodiment, the exhaust hole 380 is arranged on the first plate 310 and is on the other side of the filter space away from the dust suction port 350. The filter screen 360 separates the dust suction port 350 and the exhaust port. The exhaust port can be connected to an external exhaust fan or other exhaust device to extract the gas, thereby ensuring the exhaust effect of the exhaust hole 380 and ensuring that the dust in the air can enter the dust suction space 340 through the dust suction port 350 and then be filtered by the filter screen 360, thereby reducing the flying of dust in the outside world and improving the quality of dust removal.

[0046] As a further technical solution, the support frame 2 includes: a first rotating rod 210 rotatably set on the collecting bucket 1, and one end of the first rotating rod 210 is hinged to the collecting bucket 1; a second rotating rod 220 is rotatably set at the end of the first rotating rod 210 that is not hinged to the collecting bucket 1.

[0047] In this embodiment, the support frame 2 is used to support the dust collecting plate 3. When the support frame 2 is unfolded, the space occupied is large, which will cause inconvenience in placement and transportation. Therefore, the support frame 2 is designed to be foldable. Through the rotation of the first rotating rod 210, the first rotating rod 210 can be folded together with the second rotating rod 220 on the collection bucket 1 to reduce the floor space. The first rotating rod 210 is also hinged to the collection bucket 1 through the hinge 330 to ensure the rapid and stable rotation of the first rotating rod 210. The second rotating rod 220 is mainly used to support the dust collecting plate 3. When the first rotating rod 210 is unfolded, the position of the second rotating rod 220 cannot well unfold the dust collecting plate 3. Therefore, the angle of the second rotating rod 220 also needs to be properly adjusted to ensure that the dust collecting plate 3 is better unfolded and the dust collection effect is improved. When retracted, the rotation of the second rotating rod 220 can also ensure that the volume occupied by the support frame 2 is smaller when it is retracted, further improving the convenience of the dust collecting cover when folding.

[0048] As a further technical solution, it also includes: a connecting line 230 is arranged on the second rotating rod 220 , the connecting line 230 is detachably connected to the first plate body 310 , and the first plate body 310 is connected to the second rotating rod 220 through the connecting line 230 .

[0049] In this embodiment, the connecting line 230 is used to connect the dust collecting plate 3. Through the connection of the connecting line 230, the dust collecting plate 3 can be better unfolded. The connecting line 230 can also better control the unfolding angle and position of the dust collecting plate 3, which is convenient for the dust collecting plate 3 to be placed in the collection tank 110 as a further technical solution, and can be rotated through the third rotating rod 410. When the third rotating rod 410 rotates, the feeding roller 420 can enter or leave the collection tank 110. When the dust collecting plate 3 is unfolded, it will be placed on one side of the cold saw. When the cold saw is cutting, the cut iron filings will fall into the collection tank 110, but the cut profile will also fall into the collection tank 110. By rotating the feeding roller 420, the profile can fall onto the feeding roller 420 and will not fall into the interior of the collection tank 110. At the same time, the feeding roller 420 can also more conveniently transport the profile away from the collection bucket 1, thereby ensuring the continuity of the production process.

[0050] As a further technical solution, the third rotating rod 410 passes through one side of the collecting bucket 1 and extends out, and also includes: a plurality of locking blocks 430 are arranged on the collecting bucket 1, and the locking blocks 430 have a locking hole 440; a connecting rod 450 is slidably arranged at one end of the third rotating rod 410 extending out of the collecting bucket 1, and after the connecting rod 450 slides, the connecting rod 450 enters or leaves the locking hole 440.

[0051] In this embodiment, the third rotating rod 410 is provided with a locking rod, which can not only more conveniently rotate the third rotating rod 410, but also fix the locking rod through its own locking hole 440, thereby ensuring that the third rotating rod 410 will not rotate, thereby improving the stability of the feeding roller 420, and preventing the third rotating rod 410 from rotating during use and causing danger.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
