DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The present invention specifically provides a horizontally opening and closing powder collection and dust suppression device, comprising:

[0029] A hard dust-blocking plate 1, wherein two hard dust-blocking plates 1 are provided, and the two hard dust-blocking plates 1 are rotatably connected to any two opposite sides of the lower end of the discharge port 3 of the screw conveyor 2;

[0030] Two flexible dust-blocking thin layers 4 are provided and are respectively connected to the end surfaces of the two hard dust-blocking plates 1 to form an annular dust channel;

[0031] Slide plates 5, two slide plates 5 are provided for sliding on the upper surface of the storage hopper 6, and the two slide plates 5 are respectively located on opposite sides of the feed port 7 of the storage hopper 6;

[0032] The elastic component 8 is provided on the surface of the storage hopper 6 and is used to drive the two slides 5 to move closer to each other to close the feed port 7;

[0033] The power assembly 9 is installed at the lower end of the discharge port 3, and is used to drive the two hard dust blocking plates 1 to rotate and close to close the discharge port 3, or drive the two hard dust blocking plates 1 to rotate and open to open the discharge port 3;

[0034] When the two hard dust blocking plates 1 are closed, the ends of the hard dust blocking plates 1 are located between the two slide plates 5 so that the two slide plates 5 can be pushed apart to both sides when the two hard dust blocking plates 1 are rotated to open.

[0035] The working principle of the horizontally opening and closing powder collection and dust suppression device is as follows:

[0036] Initially, the power component 9 drives the two hard dust-blocking plates 1 to be in a closed state, that is, the lower ends of the two hard dust-blocking plates 1 are in conflict with each other, and at the same time, the flexible dust-blocking layer 4 used to close the side openings of the hard dust-blocking plates 1 is in a contracted state. At this time, the lower end of the dust channel surrounded by the two hard dust-blocking plates 1 and the two flexible dust-blocking layers 4 is closed, and the dust channel as a whole is triangular.

[0037] Then the empty storage hopper 6 is translated into a predetermined position so that the feed port 7 is located directly below the discharge port 3 , and the lower ends of the two hard dust-blocking plates 1 enter the gap reserved between the two slide plates 5 .

[0038] The two hard dust-blocking plates 1 are driven to rotate and open synchronously by the power component 9 until both hard dust-blocking plates 1 are rotated from an inclined state to a vertical state. At this time, the lower end of the dust channel is opened, and the flexible dust-blocking thin layer 4 is stretched and deformed from a triangle to a rectangle, and the dust channel is transformed from a triangular shape to a rectangular shape.

[0039] As the two rigid dust barrier panels 1 rotate and open synchronously, the lower ends of the rigid dust barrier panels 1 push the two slide plates 5 outward, causing the two slide plates 5 to open simultaneously with the two rigid dust barrier panels 1, and the opening amplitude of each slide plate 5 gradually increases. When the two rigid dust barrier panels 1 rotate to a vertical position, the distance between the two slide plates 5 reaches its maximum value, the feed port 7 is fully opened, and the dust from the discharge port 3 can enter the storage hopper 6 through the dust channel.

[0040] Since the opening process of the hard dust blocking plate 1 is from tilting to vertical, after the hard dust blocking plate 1 is vertical, the lower end of the hard dust blocking plate 1 will be inserted into the feed port 7, that is, the lower end of the dust channel surrounded by two hard dust blocking plates 1 and two flexible dust blocking layers 4 extends into the feed port 7. At this time, the upper and lower ends of the dust channel are closed to prevent dust leakage.

[0041] When the dust level in the hopper 6 reaches the upper limit, the power assembly 9 drives the two hard dust blocking plates 1 to close simultaneously, sealing the lower end of the dust passage again to prevent dust from leaking out of the screw conveyor 2. At the same time, the two slide plates 5 move closer to each other under the action of the elastic assembly 8, resealing the feed port 7 and preventing dust from leaking out of the hopper 6 during transportation.

[0042] In summary, through the dust channel surrounded by two hard dust-blocking plates 1 and two flexible dust-blocking thin layers 4, and the interaction between the hard dust-blocking plates 1 and the slide plate 5, while the two hard dust-blocking plates 1 are driven to rotate and open synchronously by the power component 9, the lower end thereof will push the two slide plates 5 outward, so that the two slide plates 5 will open the feed port 7 synchronously, and the lower end of the fully opened dust channel will extend into the feed port 7. At this time, the upper and lower ends of the dust channel are both closed to prevent dust leakage.

[0043] During the transportation of the storage hopper 6, the slide plate 5 is acted upon by the elastic component 8 to close the feed port 7 to prevent dust leakage.

[0044] Furthermore, the flexible dust-blocking thin layer 4 is an elastic film or an accordion protective cover.

[0045] Furthermore, the slide plate 5 includes a plate head 501 that contacts the hard dust barrier 1, a plate tail 503 connected to the elastic component 8, and a plate body 502 between the plate head 501 and the plate tail 503;

[0046] The side of the plate head 501 facing the hard dust-blocking plate 1 is set as an upward inclined surface 504. After the two plate heads 501 collide with each other, a triangular space 505 is formed between the two opposite inclined surfaces 504. The triangular space 505 can accommodate the lower ends of the two hard dust-blocking plates 1 in a closed state.

[0047] The advantage of the triangular space 505 is that the bottoms of the two shift heads are still in contact with each other, which can ensure the sealing of the feed port 7. At the same time, the inclined surface 504 fits with the hard dust barrier 1. The triangular space 505 with open ends formed by the two inclined surfaces 504 is convenient for the storage hopper 6 to move in or out of the work station.

[0048] Furthermore, the elastic component 8 includes a fixed plate 801 fixedly mounted on the upper surface of the storage hopper 6, and a guide rod 802 is fixedly connected to the side of the fixed plate 801 facing the slide plate 5, the other end of the guide rod 802 passes through the plate tail 503, and the end is connected to an anti-slip nut 803, and a spring 804 is provided on the outer sleeve of the guide rod 802, and the two ends of the spring 804 respectively contact the fixed plate 801 and the plate tail 503.

[0049] The guide rod 802 is used to constrain the movement paths of the two slides 5 so that the two slides 5 can only move in a straight line. When the two slides 5 move away from each other, the spring 804 is compressed; and when the two slides 5 contact each other, the spring 804 remains in a compressed state.

[0050] Furthermore, the power assembly 9 includes a cylinder 901 and a hanging plate 902 fixedly installed at the lower end of the discharge port 3, and the tail and head of the cylinder 901 are rotatably connected to the hanging plate 902 and the hard dust-blocking plate 1 respectively.

[0051] Furthermore, the air inlet and outlet of the cylinder 901 are connected to a manual air inlet valve and a solenoid valve respectively through a three-way valve and an air pipe, and the manual air inlet valve and the solenoid valve are connected to an air source. The cylinder 901 can be controlled manually or remotely.

[0052] Furthermore, the difference between the height of the lower end of the hard dust barrier 1 when closed and the height of the lower end of the hard dust barrier 1 after vertically opening is greater than the distance between the lower end of the hard dust barrier 1 and the upper surface of the storage hopper 6 when the hard dust barrier 1 is closed, so that after the hard dust barrier 1 is opened, the dust channel constructed by the hard dust barrier 1 and the flexible dust barrier layer 4 can extend into the feed port 7.

[0053] Furthermore, a flexible sealing layer is fixedly provided on one side opposite to the lower end of the two hard dust-blocking plates 1 to enhance the sealing performance of the bottom of the dust passage when the two hard dust-blocking plates 1 are closed.

[0054] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
