Of course, they are only examples and are not intended to limit the present invention.
[0029] The following is combined with Figure 1 ~Attached Figure 5 The embodiments of the present utility model are described in detail.
[0030] The embodiment of the utility model provides an exhaust gas blocking device. The exhaust gas blocking device includes: a blocking mechanism 1. The blocking mechanism 1 includes: a plurality of baffles 2 arranged in sequence along the left and right directions. It should be understood that the blocking mechanism 1 can be connected to the spray box through the rightmost or leftmost baffle 2 to be installed at the entrance of the spray box. Any two adjacent baffles 2 constitute an opening and closing unit. It should be understood that when the blocking mechanism 1 is provided with two baffles 2, these two baffles 2 constitute an opening and closing unit; when the blocking mechanism 1 is provided with three baffles 2, these three baffles 2 constitute two opening and closing units; when the blocking mechanism 1 is provided with four baffles 2, these four baffles 2 constitute three opening and closing units; and so on. A first elastic member 3 is provided on the outside of the opening and closing unit. It should be understood that one opening and closing unit corresponds to a group of first elastic members 3; each group of first elastic members 3 includes at least one first elastic member 3, and usually includes multiple first elastic members 3. The first elastic member 3 extends in the left-right direction, and the two ends are respectively connected to the two baffles 2 of the opening and closing unit to apply traction to the two baffles 2. The two baffles 2 of the opening and closing unit are hinged to each other so that the traction of the first elastic member 3 drives the two baffles 2 to flip outward relative to each other. It should be understood that the inside is toward the inside of the spray box and the outside is toward the outside; if one of the baffles 2 of the opening and closing unit is kept fixed, the first elastic member 3 will drive the other baffle 2 of the opening and closing unit to flip outward. Adjacent baffles 2 are generally hinged by hinges 15. The opening and closing unit is provided with a first limit member 4 to prevent the two baffles 2 that have flipped outward to be parallel to each other from continuing to flip outward relative to each other.
[0031] The specific implementation of the exhaust gas blocking device is described below: The exhaust gas blocking device can be installed at the inlet of the spray box of the metal sheet spraying equipment. When the metal sheet is fed from the inlet of the spray box, the metal sheet will apply a thrust to the baffle 2, causing the baffle 2 to flip inward, thereby opening the inlet of the spray box for the metal sheet to enter. After the metal sheet enters the spray box, under the traction of the first elastic member 3, the baffle 2 will automatically flip outward, quickly reset, and re-block the inlet of the spray box. The exhaust gas blocking device can significantly reduce the spraying exhaust gas escaping from the inlet of the spray box, protecting the workshop environment and the health of the staff; and it does not require an additional power source to drive, which is more energy-efficient.
[0032] Further, the first elastic member 3 is a spring; hooks or rings are provided at both ends of the spring; and a mounting portion for mounting the hooks or rings is provided on the outer side of the baffle 2. It should be understood that, in addition to the spring, the first elastic member 3 can also be made of a rubber band or other elastic materials.
[0033] Furthermore, the mounting portion is a positioning bolt 5; the hook or ring of the spring is sleeved on the rod of the positioning bolt 5, and the cap or nut of the positioning bolt 5 limits the hook or ring of the spring.
[0034] Furthermore, the blocking mechanism 1 further comprises: an ear piece 6; the ear piece 6 has a transverse piece portion 13 and a vertical piece portion 14; the positioning bolt 5 is installed on the transverse piece portion 13; the vertical piece portion 14 is connected to the baffle 2 through a connecting bolt. It should be understood that the cap or nut of the positioning bolt 5 will cooperate with the transverse piece portion 13 of the ear piece 6 to limit the hook or hanging ring of the spring. With the above structure, the first elastic member 3 can be easily installed on the baffle 2, and it is convenient to replace the first elastic member 3 later.
[0035] Furthermore, the first limit member 4 is arranged on the outside of the opening and closing unit; one section of the first limit member 4 is connected to one of the baffles 2 of the opening and closing unit through a connecting bolt; another section of the first limit member 4 extends to the outside of the other baffle 2 of the opening and closing unit.
[0036] Furthermore, two blocking mechanisms 1 are provided, which are symmetrically distributed on the left and right. It should be understood that when the inlet of the spray box is wider, it will be more stable to provide two blocking mechanisms 1 on the left and right.
[0037] Furthermore, it also includes: a left connecting plate 7; the left connecting plate 7 is hinged with the leftmost baffle 2, and is adapted to the second elastic member 8 and the second limit member 9; the traction force of the second elastic member 8 drives the leftmost baffle 2 to flip outward relative to the left connecting plate 7; when the leftmost baffle 2 flips outward to be parallel to the left connecting plate 7, the second limit member 9 prevents the leftmost baffle 2 from continuing to flip outward. It should be understood that the second elastic member 8 can be set as a spring with reference to the first elastic member 3; the installation method of the second elastic member 8 can refer to the first elastic member 3; the structure and installation method of the second limit member 9 can refer to the first limit member 4; no further details are given here. The blocking mechanism 1 can be connected to the spray box through the left connecting plate 7 to be installed at the entrance of the spray box; the left connecting plate 7 can be connected to the spray box by connecting bolts or welding. The left connecting plate 7 is usually set to be narrower to avoid occupying too much space at the entrance of the spray box; in fact, when the baffle 2 is set to be narrower, the left connecting plate 7 may not be set, but the leftmost baffle 2 is directly connected to the spray box.
[0038] Furthermore, it also includes: a right connecting plate 10; the right connecting plate 10 is hinged with the rightmost baffle 2, and is adapted to the third elastic member 11 and the third limit member 12; the traction force of the third elastic member 11 drives the rightmost baffle 2 to flip outward relative to the right connecting plate 10; when the rightmost baffle 2 flips outward to be parallel to the right connecting plate 10, the third limit member 12 prevents the rightmost baffle 2 from continuing to flip outward. It should be understood that the third elastic member 11 can be set as a spring with reference to the first elastic member 3; the installation method of the third elastic member 11 can refer to the first elastic member 3; the structure and installation method of the third limit member 12 can refer to the first limit member 4; no further details are given here. The blocking mechanism 1 can be connected to the spray box through the right connecting plate 10 to be installed at the entrance of the spray box; the right connecting plate 10 can be connected to the spray box by connecting bolts or welding. The right connecting plate 10 is usually set to be narrower to avoid occupying too much space at the entrance of the spray box; in fact, when the baffle 2 is set to be narrower, the right connecting plate 10 may not be set, but the rightmost baffle 2 is directly connected to the spray box.
[0039] The embodiment of the utility model also provides a metal sheet spraying device, which has the above-mentioned exhaust gas blocking device.
[0040] Although specific embodiments of the present invention are described above, those skilled in the art should understand that various changes or modifications may be made to these embodiments without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
