Description

Technical Field

[0001] The utility model relates to the technical field of spraying and dust reduction in injection molding workshops, in particular to a spraying and dust reduction device in injection molding workshops. Background Art

[0002] During the production process of the injection molding workshop, some dust will inevitably be generated. The dust floating in the workshop will pollute the environment and have a certain impact on the health of the workers. Improving the working environment of the workshop is a technical problem that needs to be solved in production.

[0003] Adding a spray dust reduction device in the workshop is a common method, which mainly plays the role of dust reduction, cooling and humidification. The existing workshop spray dust reduction device, when in use, uses a water pump to transport water to the spray pipe installed on the top of the workshop, and then uses the atomizing nozzle to spray dust reduction. However, the atomizing nozzle can only spray in a fixed direction. In the actual dust reduction process, the water mist spraying range is limited, the water mist coverage is not comprehensive, the dust reduction effect in the workshop is relatively poor, and the practicality is insufficient. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an injection molding workshop spray dust reduction device that can effectively expand the water mist spraying range, make the water mist coverage more comprehensive, improve the dust reduction effect in the workshop, and improve practicality.

[0027] The working principle of the spray dust reduction device for injection molding workshop of the present invention is that when in use, the L-shaped delivery pipe 1 is fixedly installed on the wall of the workshop where dust reduction is required through the U-shaped pipe clamp 4, the U-shaped pipe clamp 4 in the horizontal position of the L-shaped delivery pipe 1 is connected to the top of the workshop by bolts, and the U-shaped pipe clamp 4 in the vertical position of the L-shaped delivery pipe 1 is connected to the workshop wall by bolts, and the top rear end of the L-shaped delivery pipe 1 is fixedly connected to the wall on the other side of the workshop, so that the L-shaped delivery pipe 1 spans the top of the workshop in terms of width. When spraying dust reduction, the water pipe is connected to the L-shaped delivery pipe 1, and the other end of the water pipe is connected to the water pump to provide water source for the L-shaped delivery pipe 1, open the valve 2, start the external water pump, so that the water pump sends water into the L-shaped delivery pipe 1, and then inputs it into the spray pipe 5 through the pipe interface 3 and the connecting hose 9, and finally is sprayed from the top of the workshop through the atomizing nozzle 10. The water is atomized and sprayed out. At the same time, the motor 11 is started. By starting the motor 11, the motor 11 drives the transmission rod 12 to rotate. The transmission rod 12 drives the spray pipe 5 to rotate through the engagement of the worm shaft section 13 and the worm gear 14, so that the spray pipe 5 drives the connecting strip 16 to swing through the connecting shaft 6 on the right side, and the connecting strip 16 drives the guide shaft 17 to slide along the curved plate 15. When the guide shaft 17 approaches the proximity switch 18 on both sides of the curved plate 15, the proximity switch 18 transmits a signal to the external controller, so that the controller controls the motor 11 to reverse. Through the continuous reversal of the motor 11, the spray pipe 5 rotates back and forth, and then the atomizing nozzle 10 swings back and forth, so that the water mist is sprayed to a farther place. The arrangement of multiple groups of pipe interfaces 3 and spray pipes 5 is equidistant according to the width of the workshop, so that the water mist covers the top of the workshop from the width of the workshop.
