Description

Technical Field

[0001] This utility model relates to the field of water-saving nozzle technology, and in particular to a water-saving nozzle for cooling gravure roller molds. Background Technology

[0002] A water-saving sprinkler is a device used to reduce water consumption. It achieves water conservation by changing the shape and flow rate of the water flow and increasing the pressure of the water flow. The main application of the water-saving sprinkler is the Venturi principle, which converts the pressure energy of water into kinetic energy and draws in air. After the water and air are fully mixed, they are sprayed out at high speed, thereby reducing water consumption while maintaining the spray range and spray intensity.

[0003] Existing water-saving spray nozzles for cooling gravure printing roller molds cool the molds by spraying water mist, thus reducing water consumption. However, the sprayed water mist area is limited, making it impossible to spray a large area of ​​the gravure printing roller mold for water cooling. This increases the cooling time of the gravure printing roller mold and reduces the demolding efficiency of the gravure printing roller. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water-saving cooling nozzle for gravure printing roller molds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water-saving cooling nozzle for gravure roller molds includes a nozzle nozzle, a sleeve, and a small gear. The sleeve is sleeved on the outer wall of the nozzle nozzle. A large gear is fixedly connected to the top of the sleeve, and the small gear is located on one side of the large gear and meshes with the large gear. A drive motor is fixedly connected to the top of the small gear. A housing is fixedly connected to the outside of the nozzle nozzle, and the small gear is rotatably connected inside the housing. The drive motor is fixedly connected inside the housing, and the sleeve is rotatably connected inside the housing. The large gear is located inside the housing. A retaining bracket is fixedly connected to the outside of the bottom end of the sleeve, and a splash plate is fixedly connected to the bottom end of the retaining bracket.

[0007] As a further embodiment of this utility model, a water channel is provided through one side of the fixing frame, a conical frame is fixedly connected to the bottom of the inner side of the splash plate, and several flushing plates are provided inside the nozzle of the connecting pipe.

[0008] As a further embodiment of this utility model, several of the aforementioned booster plates are fixedly connected around the inner wall of the nozzle of the connecting pipe, and the nozzle of the connecting pipe is located at the top of the splash plate.

[0009] As a further embodiment of this utility model, the bottom end of the nozzle is provided with a water outlet, which is located at the bottom of the booster plate, and a limit bracket is fixedly connected to one side of the nozzle.

[0010] As a further embodiment of this utility model, the top of the limiting frame is attached to the bottom side of the fixing frame and the sleeve, and the water outlet is located at the top of the conical frame.

[0011] As a further embodiment of this utility model, the bottom of the limiting frame is provided with a water baffle plate, which is fixedly connected to the bottom end of the nozzle of the connecting pipe and is located in the middle of the fixing frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the operator starts the spraying device, the output shaft of the drive motor drives the small gear to rotate. The small gear meshes with the large gear on the outside of the sleeve, causing the small gear to drive the large gear to rotate. The sleeve and the splash plate follow the large gear and rotate rapidly outside the nozzle of the connector. The water flows into the splash plate through the nozzle of the connector. The splash plate drives the water flow to rotate rapidly, causing the water flow to be dispersed by the internal teeth of the splash plate to form a finer water mist. The rotating splash plate quickly throws out the water mist, which increases the contact area between the water mist and the gravure printing roller mold. At the same time, it also increases the water mist range and splash speed, thereby shortening the cooling time of the gravure printing roller mold and improving the demolding efficiency of the gravure printing roller mold.

[0014] 2. Water flows into the nozzle and forms a water column. Several booster plates surround the inner wall of the nozzle, which resists the water flow, disperses the water flow outside the column, and increases the impact force at the center of the column. The water column diameter is reduced and sprayed out through the outlet, forming a strong water pressure. The water column impacts the conical frame and rapidly splits and hits the splash plate. The splash plate is then dispersed into a water mist by rotation. This provides stronger flushing and spraying force with the same water consumption, thereby reducing water demand.

[0023] Reference Figures 1-4 A water-saving cooling nozzle for gravure roller molds includes a nozzle 1, a sleeve 2, and a pinion 3. The sleeve 2 is sleeved on the outer wall of the nozzle 1. A large gear 201 is fixedly connected to the top of the sleeve 2. The pinion 3 is located on one side of the large gear 201 and meshes with the large gear 201. A drive motor 4 is fixedly connected to the top of the pinion 3. A housing 5 is fixedly connected to the outside of the nozzle 1. The pinion 3 is rotatably connected inside the housing 5. The drive motor 4 is fixedly connected inside the housing 5. The sleeve 2 is rotatably connected inside the housing 5. The large gear 201 is located inside the housing 5. A retaining bracket 202 is fixedly connected to the outside of the bottom of the sleeve 2. A splash plate 204 is fixedly connected to the bottom of the retaining bracket 202.

[0024] When in use, when the operator starts the spray device, the output shaft of the drive motor 4 drives the small gear 3 to rotate. The small gear 3 meshes with the large gear 201 on the outside of the sleeve 2, causing the small gear 3 to drive the large gear 201 to rotate. The sleeve 2 and the splash plate 204 follow the large gear 201 and rotate rapidly outside the nozzle 1. The water flows into the splash plate 204 through the nozzle 1. The splash plate 204 drives the water flow to rotate rapidly, causing the water flow to be dispersed by the internal teeth of the splash plate 204 to form a finer water mist. The splash plate 204 rotates and quickly throws out the water mist, increasing the contact area between the water mist and the gravure roller mold. At the same time, it also increases the water mist range and splash speed, thereby shortening the cooling time of the gravure roller mold and improving the demolding efficiency of the gravure roller mold.

[0025] In this embodiment, a water channel 203 is provided through one side of the fixed frame 202, a conical frame 205 is fixedly connected to the bottom of the inner side of the splash plate 204, and several flushing plates 101 are provided inside the nozzle 1.

[0026] In use, the water channel 203 is opened on the fixing frame 202 to facilitate the water mist to pass through and to avoid the fixing frame 202 from blocking and affecting the water mist splashing. The water flow enters the nozzle 1 of the connecting pipe to form a water column. Several impact plates 101 surround the inner wall of the nozzle 1 of the connecting pipe, and the water flow is resisted, which disperses the water flow outside the water column and increases the impact force at the center of the water column.

[0027] In this embodiment, several booster plates 101 are fixedly connected around the inner wall of the nozzle 1, and the nozzle 1 is located on top of the splash plate 204.

[0028] When in use, the water column diameter is reduced and sprayed out through the outlet 102, forming a strong water pressure, which causes the water column to impact the conical frame 205, and the water column to quickly split and hit the splash plate 204.

[0029] In this embodiment, the bottom end of the nozzle 1 is provided with a water outlet 102, which is located at the bottom of the booster plate 101. A limit bracket 6 is fixedly connected to the outside of the nozzle 1.

[0030] When in use, the water is dispersed into a mist by the rotating splash plate 204, which provides stronger rinsing and spraying power with the same amount of water, thereby reducing the water demand.

[0031] In this embodiment, the top of the limiting frame 6 is attached to the bottom side of the fixing frame 202 and the sleeve 2, and the water outlet 102 is located at the top of the conical frame 205.

[0032] During use, the limiting bracket 6 limits the sleeve 2 to prevent the sleeve 2 from sliding up and down during rotation. At the same time, the limiting bracket 6 blocks the bottom of the sleeve 2 to prevent water mist that diffuses in the air from entering the inner wall of the outer shell 5 through the inner wall of the sleeve 2, increasing the humidity of the air inside the outer shell 5 and causing oxidation to the large gear 201 and the lower gear.

[0033] In this embodiment, the bottom of the limiting frame 6 is provided with a water baffle 7, which is fixedly connected to the bottom end of the nozzle 1 through the pipe and is located in the middle of the fixing frame 202.

[0034] When in use, the water baffle 7 blocks the water droplets formed inside the splash plate 204, preventing the water droplets from splashing upwards and affecting the formation of a mist-like umbrella spray, thereby reducing the contact area of ​​the water mist, increasing water consumption and affecting water conservation.

[0035] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: Water flows into the nozzle 1 to form a water column. Several booster plates 101 surround the inner wall of the nozzle 1, causing resistance to the water flow and dispersing the water flow outside the water column, increasing the impact force at the center of the water column. The diameter of the water column is reduced and sprayed out through the outlet 102, forming a strong water pressure, causing the water column to impact the conical frame 205. The water column quickly splits and impacts the splash plate 204, and is dispersed into water mist by the rotation of the splash plate 204. In this way, stronger flushing and spraying force can be provided with the same water consumption, thereby reducing the water demand. When the operator starts the sprinkler device, the drive motor... The output shaft of machine 4 drives the small gear 3 to rotate. The small gear 3 meshes with the large gear 201 on the outside of the sleeve 2, causing the small gear 3 to drive the large gear 201 to rotate. The sleeve 2 and the splash plate 204 follow the large gear 201 and rotate rapidly outside the nozzle 1. The water flows into the splash plate 204 through the nozzle 1. The splash plate 204 drives the water flow to rotate rapidly, causing the water flow to be dispersed by the internal teeth of the splash plate 204 to form a finer water mist. The splash plate 204 rotates and quickly throws out the water mist, which increases the contact area between the water mist and the gravure roller mold. At the same time, it also increases the water mist range and splash speed, thereby shortening the cooling time of the gravure roller mold and improving the demolding efficiency of the gravure roller mold.
