Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, and in particular to an energy-saving water-based paint spraying device. Background Art

[0002] Spraying devices (also called spraying equipment or coating equipment) are produced in the development of industrial technology, especially in an environment with an increasingly high degree of automation. The main function of the spraying device is to spray the paint evenly on the surface of the workpiece to form a protective or decorative layer. It is widely used in many fields such as automobile manufacturing, aerospace, coatings industry, furniture industry, mold industry, etc. For example, in automobile manufacturing, spraying devices are used for spraying the exterior and interior of automobiles to achieve a variety of effects such as matte, color change, frosting, etc.

[0003] As disclosed in the Chinese patent: Energy-saving spraying device for construction coatings, application number: CN202321401822.1, a spray assembly is installed on the upper part of the fixed frame, and a circulation assembly is installed on the outside of the fixed frame at a position corresponding to the spray assembly. The spray assembly includes two adjustment frames installed on the upper part of the fixed frame, and the inner upper parts of the two adjustment frames are slidably connected to a connecting frame. A spray pipe is installed between the front parts of the two connecting frames, and atomizing nozzles are equidistantly installed on the front surface of the spray pipe. The adjustment frame and the connecting frame are connected by an adjustment mechanism. The circulation assembly includes a storage box installed on the outer bottom of the fixed frame, and a connecting pipe is installed at the liquid outlet end of the storage box. The energy-saving spraying device for construction coatings described in the utility model can enable the overall device to recycle the coating, achieve more energy-saving use of coatings, improve the practicality of the overall device, and bring better prospects for use.

[0004] However, in the above technical solution, when adjusting the height of the adjusting frame, two motors are required to adjust the height of the two adjusting frames, which is costly. Moreover, when spraying, due to the different sizes of the workpieces, more or less atomizing nozzles are required. In the above technical solution, no matter how many atomizing nozzles are used, the flow range of the spray pipe is the same. This results in that once only a small number of atomizing nozzles are needed, the inside of the spray pipe still needs to fill the flow range of the entire spray pipe, and loss is inevitable during the circulation process, which results in waste. Utility Model Content

[0005] The main purpose of the present utility model is to provide an energy-saving water-based paint spraying device, which can effectively solve the problem in the background technology that when adjusting the height of the adjusting frame, two motors are needed to adjust the height of the two adjusting frames, which is costly. Moreover, when spraying, due to the different sizes of the workpieces, more and fewer atomizing nozzles are needed. In the above technical solution, no matter how many atomizing nozzles are used, the flow range of the spray pipe is the same. This results in that once only a small number of atomizing nozzles are needed, the flow range of the entire spray pipe still needs to be filled inside the spray pipe, and loss is inevitable in the circulation process, thus causing waste.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A water-based paint energy-saving spraying device includes a base, two slide grooves are provided on the base, a connecting frame is slidingly provided in the slide grooves, a filter net bag and a spray pipe are provided on the connecting frame, a first conveying pipe is provided on one side of the filter net bag, a plurality of atomizing nozzles and a plurality of cut-off mechanisms are provided on the spray pipe, a second conveying pipe is provided on one side of the spray pipe, a threaded column is threadedly provided on one side below the connecting frame, the threaded column is rotatably connected to the base, a sprocket is provided on the threaded column, a transmission chain is provided on the sprocket, and a motor is fixedly installed on one side of the base.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) When the present invention is used, first determine which atomizing nozzles do not need to be used based on the area to be sprayed, then rotate the knob on the side of the atomizing nozzle that does not need to be used, and use the cut-off mechanism to cut off the flow range of the spray pipe to complete the change of the flow range of the spray pipe. The flow range of the spray pipe can be flexibly changed accordingly according to the area to be sprayed to prevent waste.

[0015] (2) When the height of the connecting frame needs to be adjusted, the motor is first started, and the motor drives a threaded column to rotate. At the same time, this threaded column drives another threaded column to rotate through a sprocket and a transmission chain, thereby driving the connecting frame threadedly connected to it to move to one side through the two threaded columns. Two connecting frames can be driven to move by one motor, thereby reducing the cost of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

Obviously, the embodiments described 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.

[0023] like Figure 3 and Figure 4 As shown, in another embodiment of the present invention, the shut-off mechanism 8 includes a mechanism base 801, on which two first transmission tubes 802 are fixedly provided, a second transmission tube 8011 is rotatably provided between the two first transmission tubes 802, a gear ring 803 is provided on the second transmission tube 8011, and a first semicircular stopper 804 and a second semicircular stopper 805 are fixedly provided on the inner walls of the first transmission tube 802 and the inner walls of the second transmission tube 8011, respectively;

[0024] A sealing ring 806 is provided on one side of the first transmission tube 802 close to the second transmission tube 8011, and a gear 807 is meshed with the gear ring 803 on one side. A rotating column 808 is provided on the gear 807, and a knob 809 is provided at one end of the rotating column 808. A pointer 8010 is provided on the knob 809. A through groove 8012 is provided on the first semicircular stopper 804. When it is necessary to cut off the paint liquid in the spray tube 5, the knob 809 is first turned. The knob 809 drives the gear 807 to rotate through the rotating column 808, and the gear 807 drives the gear ring 803 to rotate so that the gear ring 803 rotates with the second transmission tube 801 1 rotates as the center, the gear ring 803 drives the second transmission tube 8011 to rotate, and the second transmission tube 8011 drives the second semicircular stopper 805 to rotate, so that the second semicircular stopper 805 and the first semicircular stopper 804 are misaligned with each other, and the inner cavity of the first transmission tube 802 is blocked by the second semicircular stopper 805. At this time, the paint liquid in the spray tube 5 will be cut off, and at the same time, the inner cavity of the second transmission tube 8011 will be in the through groove 8012. If there is paint liquid remaining in the inner cavity of the second transmission tube 8011, the paint liquid will flow to the filter net bag 4 through the through groove 8012, so that the paint liquid remaining in the inner cavity of the second transmission tube 8011 can be collected conveniently to prevent waste.

[0025] The working principle of this water-based paint energy-saving spraying device:

[0026] When in use, first determine which atomizing nozzles 7 do not need to be used based on the area that needs to be sprayed, and then rotate the knob 809 close to the side of the atomizing nozzle that does not need to be used. The knob 809 drives the gear 807 to rotate through the rotating column 808, and the gear 807 drives the gear ring 803 to rotate so that the gear ring 803 rotates with the second transmission tube 8011 as the center, and the gear ring 803 drives the second transmission tube 8011 to rotate, and the second transmission tube 8011 drives the second semicircular stopper 805 to rotate, so that the second semicircular stopper 805 and the first semicircular stopper 804 are misaligned with each other, and the inner cavity of the first transmission tube 802 is blocked by the second semicircular stopper 805, thereby using the intercepting mechanism 8 to cut off the flow range of the spraying tube 5, thereby completing the change of the flow range of the spraying tube 5. The modification can flexibly change the flow range of the spray pipe 5 according to the spraying area to prevent waste, and then the atomizing nozzle 7 can be used for spraying, and the filter net bag 4 can be used to collect and filter the excess paint liquid, and then the filtered paint liquid is transported to the designated position through the first conveying pipe 6 for easy recycling. When the height of the connecting frame 3 needs to be adjusted, first start the motor 13, and the motor 13 drives a threaded column 10 to rotate. At the same time, this threaded column 10 drives another threaded column 10 to rotate through the sprocket 11 and the transmission chain 12, so that the connecting frame 3 threadedly connected to it is driven to one side by the two threaded columns 10. The two connecting frames 3 can be driven to move by one motor 13, thereby reducing the cost of the device.

[0027] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
