[0002] During the process of spraying plastic on the guardrail board, the hanging bracket drags the guardrail board slowly through the coverage range of the spray nozzle of the spray molding machine, and the spray molding machine sprays plastic on the guardrail board. However, in addition to a part of the powder sprayed by the spray nozzle of the spray molding machine adhering to the outer layer of the guardrail board, a large amount of powder will be scattered under the action of gravity. It is necessary to install a negative pressure absorption device at the bottom of the spray molding machine to recover the spray powder. However, the current powder recovery device of the spray molding machine recovers the powder by continuously sucking air.

[0016] See also Figure 1-Figure 4 The utility model provides the following technical solutions: a guardrail plate spraying device, including a guardrail plate spraying machine body 1, a spraying powder recovery chamber 2 is fixedly connected to the bottom end of the guardrail plate spraying machine body 1, and the inner walls on both sides of the spraying powder recovery chamber 2 are hinged with flip sealing plates 21, and a plurality of evenly distributed support bars 22 are provided at the bottom ends of the two flip sealing plates 21, and elastic closing plates 23 are fixedly connected to the bottom ends of the plurality of support bars 22, and a multi-directional bulk material nozzle 3 is provided below the flip sealing plate 21, and a negative pressure absorption groove plate 31 is installed on the inner wall of the spraying powder recovery chamber 2.

[0017] In this embodiment: during the process of spraying the guardrail, the output shaft of the elastic closing plate 23 is retracted, the support bar 22 is in a low position, the flip sealing plate 21 flips and falls under the action of gravity, and the powder sprayed by the guardrail spraying machine body 1 falls into the internal space of the spray powder recovery chamber 2 under the action of gravity. After a certain period of accumulation, the output shaft of the elastic closing plate 23 repeatedly expands and contracts, driving the flip sealing plate 21 to vibrate, so as to shake off the powder attached to the surface of the flip sealing plate 21 into the spray powder recovery chamber 2, and then, The output shaft of the elastic sealing plate 23 extends out to drive the flip sealing plate 21 to flip upward, and the top opening of the spray powder recovery chamber 2 is closed by the two flip sealing plates 21. Then the multi-directional bulk material nozzle 3 sprays out a high-speed airflow, and the powder deposited in the spray powder recovery chamber 2 is driven to float in the air through the multi-directional airflow. The negative pressure absorption slot plate 31 simultaneously sucks the gas in the spray powder recovery chamber 2 to absorb the powder. When the flip sealing plate 21 flips downward and opens, the multi-directional bulk material nozzle 3 and the negative pressure absorption slot plate 31 The multi-directional bulk material nozzle 3 sprays high-speed gas in multiple directions, which can blow and lift the powder at various positions in the closed space, so as to facilitate the recovery of the powder by the negative pressure absorption slot plate 31, and the negative pressure absorption slot plate 31 can be used to absorb the collected powder in the closed environment. When the plate 31 sucks the gas in the inner wall space of the spray powder recovery chamber 2, the powder enters the negative pressure absorption slot plate 31 along with the gas. The installation position of the flip sealing plate 21 is lower than the opening position of the spray powder recovery chamber 2, so that when the multi-directional bulk nozzle 3 and the negative pressure absorption slot plate 31 recover the powder in the closed space, the powder dropped from the guardrail plate spray molding machine body 1 can be gathered at the top of the flip sealing plate 21. When the flip sealing plate 21 flips and falls again, the spray powder falls downward through the space between the two flip sealing plates 21.

[0018] The top of several support bars 22 is provided with an adjustable telescopic rod 24, and the flip sealing plate 21 is in conflict with the adjustable telescopic rod 24; by setting the adjustable telescopic rod 24, it can be filled between the two flip sealing plates 21 when the flip sealing plate 21 is flipped and closed, so as to close the gap between the two flip sealing plates 21, thereby improving the sealing effect of the top opening of the spray powder recovery chamber 2, and avoiding affecting the falling of the spray powder. The adjustable telescopic rod 24 is a continuous elastic plate, and the support bars 22 are distributed at intervals to form through holes to provide space for the powder to fall.

[0019] The inner wall of the spray powder recovery chamber 2 is provided with a clearance groove 25, and the flip sealing plate 21 extends into the clearance groove 25; by setting the clearance groove 25, the installation of the rotating shaft of the flip sealing plate 21 can be facilitated, and the side wall of the flip sealing plate 21 can limit the flip sealing plate 21.

[0020] A blowing connecting pipe 32 is fixedly connected to one side of the multi-directional bulk material nozzle 3, and a suction connecting pipe 33 is fixedly connected to one side of the negative pressure absorption slot plate 31. The multi-directional bulk material nozzle 3 and the negative pressure absorption slot plate 31 are respectively located on both sides of the elastic closing plate 23; by arranging the blowing connecting pipe 32 and the suction connecting pipe 33, it is convenient to connect the multi-directional bulk material nozzle 3 and the negative pressure absorption slot plate 31 with the spray powder recovery machine. In actual use, the negative pressure absorption slot plate 31 is connected to the air inlet of the spray powder recovery machine through the suction connecting pipe 33, and the multi-directional bulk material nozzle 3 is connected to the exhaust port of the spray powder recovery machine through the negative pressure absorption slot plate 31, forming a gas circulation, and the spray powder is filtered and recovered by the filtering device inside the spray powder recovery machine.

[0021] A negative pressure anti-overflow groove plate 4 is installed on the inner wall of the guardrail board spray molding machine body 1, and the negative pressure anti-overflow groove plate 4 is located at the edge of the guardrail board spray molding machine body 1; by setting the negative pressure anti-overflow groove plate 4, the powder that drifts to the edge of the guardrail board spray molding machine body 1 can be absorbed by negative pressure to prevent the powder from escaping to the outside of the guardrail board spray molding machine body 1 and affecting environmental safety. The negative pressure anti-overflow groove plate 4 is located at the edge of the guardrail board spray molding machine body 1 and can be away from the spray molding nozzle of the guardrail board spray molding machine body 1, so as to reduce the influence of the air sucked by the negative pressure anti-overflow groove plate 4 on the powder at the nozzle of the guardrail board spray molding machine body 1.

[0022] The working principle and use process of the utility model are as follows: during the process of spraying the guardrail plate, the output shaft of the elastic closing plate 23 contracts, the support bar 22 is in a low position, the flip sealing plate 21 flips and hangs down under the action of gravity, and the powder sprayed by the guardrail plate spraying machine body 1 falls into the internal space of the spray powder recovery chamber 2 under the action of gravity. After a certain period of accumulation, the output shaft of the elastic closing plate 23 repeatedly expands and contracts, driving the flip sealing plate 21 to vibrate, so as to shake off the powder attached to the surface of the flip sealing plate 21 into the spray powder recovery chamber 2, and then the output shaft of the elastic closing plate 23 extends to drive the flip sealing plate 21 to vibrate. The rotary sealing plate 21 flips upward, and the top opening of the spray powder recovery chamber 2 is closed by the two flip sealing plates 21. Then the multi-directional bulk nozzle 3 sprays out a high-speed airflow, and the multi-directional airflow drives the powder deposited in the spray powder recovery chamber 2 to float in the air. The negative pressure absorption slot plate 31 simultaneously sucks the gas in the spray powder recovery chamber 2 to absorb the powder. By sucking the powder in a closed space, the negative pressure attraction is avoided to accelerate the falling of the powder scattered in the guardrail board spray molding machine body 1, so that the spray powder can fully contact and adhere to the bottom of the guardrail board, thereby improving the spraying effect of the bottom of the guardrail board.
