Description

Technical Field

[0001] This utility model relates to the field of inkjet printing equipment technology, and in particular to a quantitative spraying device for inkjet printing paint. Background Technology

[0002] In many fields such as advertising production, artistic creation, and interior and exterior decoration, inkjet printing is widely used as an efficient and expressive way of presenting images. During the inkjet printing process, the amount of inkjet paint used is crucial, as it directly affects the quality and effect of the inkjet print.

[0003] Current inkjet printing operations mostly rely on manual control of the spraying amount, depending on the operator's experience and feel to adjust the amount of paint sprayed. However, due to the varying experience and skill levels of different operators, it is difficult to ensure that the amount of paint sprayed each time is uniform. This leads to problems such as inconsistent color depth, blurred edges of patterns, and uneven overall texture in the inkjet prints, which seriously affect the quality and artistic expression of the inkjet prints. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quantitative spraying device for inkjet paint, which has the advantages of quantitative spraying and solves the problem that existing inkjet printing operations mostly rely on manual control of the spraying amount, making it difficult to ensure that the amount of paint sprayed each time is uniform.

[0005] This utility model provides the following technical solution: a quantitative spraying device for inkjet paint, including a bracket and a one-way nozzle. A handle and a grip are fixedly connected to the bottom surface of the bracket. A trigger is provided on the surface of the grip. A quantitative spraying assembly is provided on the top surface of the bracket. The quantitative spraying assembly includes a telescopic rod and a quantitative barrel fixedly connected to the top surface of the bracket. A piston is provided inside the quantitative barrel. A positioning plate is fixedly connected between the inner wall surfaces of the quantitative barrel. Inlet and outlet ports are evenly opened on the surface of the positioning plate. A connecting pipe is fixedly connected to the top surface of the quantitative barrel. A one-way valve is provided inside the connecting pipe. An observation window is opened on the surface of the quantitative barrel. A scale is provided on the surface of the quantitative barrel near the observation window. A loading assembly is provided on the top of the connecting pipe. The bracket is the supporting foundation of the entire device, providing an installation platform for other components, ensuring that each component functions in a suitable position and angle, and guaranteeing the stability of the overall structure and ease of operation of the device.

[0006] Preferably, the output shaft of the telescopic rod passes through one end of the metering barrel and is fixedly connected to the surface of the piston near the end of the telescopic rod. The piston is slidably connected inside the metering barrel. The output shaft of the telescopic rod passes through the metering barrel and is fixedly connected to the piston. Under the control of the control module, the piston can be driven to reciprocate inside the metering barrel, providing power for the intake and spraying of the coating, and realizing the quantitative delivery of the coating.

[0007] Preferably, the bottom outlet of the connecting pipe is located on the side of the positioning plate away from the piston, and the one-way nozzle is located on the surface of the metering barrel away from the telescopic rod and is fixedly connected to the inside of the metering barrel. The one-way nozzle is fixedly connected to the inside of the metering barrel and is the outlet for the paint to be sprayed out. The one-way design can ensure that the paint can only be sprayed out from the metering barrel, preventing outside air or impurities from entering the metering barrel, ensuring the smoothness of the spraying process and the quality of the paint.

[0008] Preferably, the handle is internally equipped with a control module and a battery module. Both the control module and the battery module are electrically connected to the telescopic rod and the start trigger. The start trigger is located on the surface of the handle. By pressing the start trigger, the operator can trigger the control module, thereby controlling the movement of the telescopic rod and other components to start the equipment and perform the spraying operation, allowing the operator to easily control the spraying timing.

[0009] Preferably, the filling assembly includes a conical hopper fixedly connected to the top surface of the connecting pipe, a filter plate fixedly connected to the bottom center surface of the conical hopper, a filling barrel threadedly connected to the inside of the conical hopper, an mounting plate fixedly connected to the inner wall surface of the conical hopper, scrapers fixedly connected to the side surface of the mounting plate near the filling barrel, an opening at the end of the filling barrel near the conical hopper, and an air inlet fixedly connected to the side surface of the filling barrel away from the opening. The filling assembly is used to add paint into the metering barrel and has filtering and other functions to ensure the quality of the paint entering the metering barrel.

[0010] Preferably, the filter plate is positioned directly above the connecting pipe, and the scraper abuts against the inner wall surface of the loading tank on the side away from the mounting plate. The filter plate, positioned directly above the connecting pipe, filters the paint entering the connecting pipe, removing impurities and particles from the paint, preventing impurities from entering the metering tank and affecting the spraying quality and normal operation of the equipment.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Through the precise coordination of components such as the telescopic rod, piston, metering bucket, and positioning plate in the metering spraying assembly, precise metering of inkjet paint is achieved. Operators can observe the amount of paint entering the metering bucket in real time through the observation window and scale to ensure that the amount of paint sprayed each time is accurate. This precise metering spraying method not only improves the uniformity and consistency of the inkjet printing, but also avoids inkjet printing quality problems caused by too much or too little paint, such as uneven color depth and blurry patterns, thereby significantly improving the overall quality of the inkjet print.

[0013] 2. Through components such as the conical hopper, filter plate, filling bucket, and scraper in the loading assembly, rapid filling and effective filtration of paint are achieved, reducing the impact of impurities in the paint on the spraying effect. At the same time, the scraper design can also scrape off the paint residue on the inner wall of the filling bucket when it is unscrewed and rotated, further reducing paint waste. In addition, the operator can easily control the start and stop of the spraying equipment by simply pulling and releasing the start trigger, realizing continuous quantitative spraying operations and greatly improving work efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 - Figure 3This utility model provides an embodiment of a metering spraying device for inkjet paint, comprising a bracket 1 and a one-way nozzle 2. A handle 3 and a lever 4 are fixedly connected to the bottom surface of the bracket 1. A trigger 5 is provided on the surface of the lever 4. A metering spraying assembly 6 is provided on the top surface of the bracket 1. The metering spraying assembly 6 includes a telescopic rod 61 and a metering tank 62 fixedly connected to the top surface of the bracket 1. A piston 63 is provided inside the metering tank 62. A positioning plate 64 is fixedly connected between the inner wall surfaces of the metering tank 62. Inlet and outlet ports 65 are evenly distributed on the surface of the positioning plate 64. A connecting pipe 66 is fixedly connected to the top surface of the metering tank 62. A one-way valve 67 is provided inside the connecting pipe 66. An observation window 68 is provided on the surface of the metering tank 62. A scale 69 is provided on the surface of the barrel 62 near the observation window 68. A feeding assembly 7 is provided on the top of the connecting pipe 66. The output shaft of the telescopic rod 61 passes through one end of the metering barrel 62 and is fixedly connected to the surface of the piston 63 near the end of the telescopic rod 61. The piston 63 is slidably connected inside the metering barrel 62. The bottom outlet of the connecting pipe 66 is located on the side of the positioning plate 64 away from the piston 63. The one-way nozzle 2 is located on the surface of the metering barrel 62 away from the telescopic rod 61 and is fixedly connected to the inside of the metering barrel 62. The handle 4 contains a control module and a battery module. Both the control module and the battery module are electrically connected to the telescopic rod 61 and the start trigger 5. The handle 3 is fixedly connected to the bottom surface of the bracket 1 for easy handholding by the operator. The device moves and positions itself during the printing process, allowing operators to flexibly control the equipment for printing operations at different locations. The handle 4 is fixedly connected to the bottom surface of the bracket 1, providing a gripping position for stable operation. An internal control module and battery module provide power to the electrical components, and the control module controls the telescopic rod 61 and other electrical components. The metering spraying assembly 6 is a key component, enabling precise metering of the printing paint. The metering tank 62 serves as a storage and metering container for the paint; its internal space holds the paint, and its structural design and related components work together to ensure precise metering. The piston 63 is slidably connected inside the metering tank 62, and moves along the telescopic rod 61. The piston 63 moves within the metering tank 62, changing its volume to achieve paint intake and discharge. The piston 63 fits tightly against the inner wall of the metering tank 62 to prevent paint leakage. A positioning plate 64 is fixedly connected to the inner wall surface of the metering tank 62, with evenly spaced inlet and outlet ports 65. During piston 63 movement, the positioning plate 64 positions and limits the piston 63's movement. The bottom outlet of the connecting pipe 66 is located on the side of the positioning plate 64 away from the piston 63, and its top is fixedly connected to the loading assembly 7. A one-way valve 67 is installed inside. The connecting pipe 66 serves as the paint delivery channel between the loading assembly 7 and the metering tank 62. The one-way valve 67 ensures that paint can only enter the metering tank 62 from the loading assembly 7, preventing paint backflow.A one-way valve 67 is installed inside the connecting pipe 66 to control the unidirectional flow of the paint, ensuring the correct conveying direction of the paint between the loading assembly 7 and the metering tank 62, preventing backflow of the paint, and ensuring the accuracy of metered spraying. The observation window 68 allows operators to easily observe the paint level in the metering tank 62, providing intuitive information and facilitating timely monitoring of the spraying progress and paint volume. A scale 69 is installed on the surface of the metering tank 62 near the observation window 68, working in conjunction with the observation window 68. Operators can accurately read the volume of paint entering the metering tank 62 through the observation window 68 and the scale 69. The system allows for precise quantitative control of the paint volume. The one-way nozzle 2 has a square structure, ensuring that the paint is sprayed out in a square spray area. Pressing the start trigger 5 once sprays the paint from the metering tank 62 once. During continuous spraying, the amount of paint in each square spray area remains uniform. This cyclical operation allows the operator to continuously apply quantitative paint in each square spray area by repeatedly pulling and releasing the start trigger 5, providing an efficient and high-quality solution for inkjet printing.

[0020] Please see Figure 1 - Figure 3 The loading assembly 7 includes a conical hopper 71 fixedly connected to the top surface of the connecting pipe 66. A filter plate 72 is fixedly connected to the bottom center surface of the conical hopper 71. A loading barrel 73 is threadedly connected to the inside of the conical hopper 71. An mounting plate 74 is fixedly connected to the inner wall surface of the conical hopper 71. Scrapers 75 are fixedly connected to the side surface of the mounting plate 74 near the loading barrel 73. The end of the loading barrel 73 near the conical hopper 71 is open, and an air inlet 76 is fixedly connected to the side surface of the loading barrel 73 away from the opening. The filter plate 72 is positioned directly above the connecting pipe 66. The scrapers 75 abut against the inner wall surface of the loading barrel 73 on the side away from the mounting plate 74. The bottom of the conical hopper 71... A filter plate 72 is fixedly connected to the center surface, providing a transition and guidance for the paint to enter the connecting pipe 66, allowing the paint to flow smoothly into the connecting pipe 66. At the same time, the filter plate 72 can perform preliminary filtration of the paint. The loading tank 73 is internally threaded to the conical hopper 71. The loading tank 73 is used to store the paint to be sprayed. It can be easily installed on the conical hopper 71 or removed for feeding through the threaded connection. The air inlet 76 can ensure stable air pressure inside the loading tank 73, facilitating smooth paint flow. During the installation or removal of the loading tank 73, the air inlet 76 can balance the air pressure inside and outside the loading tank 73, allowing the paint to flow smoothly and avoiding the problem of poor paint flow due to air pressure difference.

[0021] Working principle: Before use, fill the filling tank 73 with spray paint. Thread the filling tank 73 into the conical hopper 71. The air inlet 76 at the end furthest from the opening is used to balance the air pressure inside and outside the filling tank 73, ensuring smooth paint flow. After the filling tank 73 is installed, the scraper 75 on the mounting plate 74, which is fixedly connected to the inner wall of the conical hopper 71, will abut against the inner wall of the filling tank 73. The scraper 75 can then scrape away any remaining paint on the inner wall of the filling tank 73 when it is unscrewed and rotated, reducing paint waste and facilitating cleaning. When paint flows from the filling tank 73 into the connecting pipe 66, the filter plate 72 intercepts impurities in the paint, preventing them from entering the metering tank 62 and affecting the spraying effect. Initially, when the positioning plate 6... 4. When the cavity on the side away from the telescopic rod 61 is full, the operator holds the handle 3 and the handle 4 at the bottom of the bracket 1 and pulls the start trigger 5. After receiving the signal, the control module inside the handle 4 will send a command to the telescopic rod 61 to control the output shaft of the telescopic rod 61 to move in the direction of the telescopic rod 61. Since the output shaft of the telescopic rod 61 passes through one end of the metering tank 62 and is fixedly connected to the surface of the piston 63 near the end of the telescopic rod 61, the movement of the output shaft of the telescopic rod 61 will drive the piston 63 to slide inside the metering tank 62. At this time, the space inside the metering tank 62 near the one-way nozzle 2 will generate negative pressure due to the movement of the piston 63. Under the action of negative pressure, the one-way valve 67 in the connecting pipe 66 will be opened, and the paint in the filling tank 73 will be released due to the pressure difference. After being filtered by the filter plate 72 at the bottom of the conical hopper 71, the coating enters the space near the one-way nozzle 2 inside the metering tank 62 through the connecting pipe 66. The positioning plate 64, positioned between the inner wall surfaces of the metering tank 62, has evenly spaced inlet and outlet ports 65 that allow the coating to pass through smoothly, ensuring that the coating fills the space on that side of the metering tank 62 evenly. During the process of the coating entering the metering tank 62, the operator can observe the amount of coating entering the metering tank 62 in real time through the observation window 68 on the surface of the metering tank 62 and the scale 69 located near the observation window 68. When the amount of coating reaches the set value, the operator releases the start trigger 5. After receiving the signal, the control module controls the telescopic rod 61 to stop working, at which point the piston 63 stops moving. The one-way valve 67 inside the connecting pipe 66 will also close under the action of its own internal structure to prevent the paint in the metering tank 62 from flowing back into the filling tank 73. At this time, the one-way nozzle 2 is aligned with the area to be painted, and the start trigger 5 is pulled again. After receiving the signal, the control module will control the output shaft of the telescopic rod 61 to move in the reverse direction, thereby driving the piston 63 to slide in the reverse direction inside the metering tank 62. The reverse movement of the piston 63 will compress the space inside the metering tank 62 near the one-way nozzle 2, causing the pressure of the paint in this space to increase rapidly. Under the action of pressure, the paint will force open the internal structure of the one-way nozzle 2. The internal structure of the one-way nozzle 2 is similar to the principle of the one-way valve 67. It opens when the pressure reaches a certain level to ensure that the paint flows out in one direction and is metered out from the one-way nozzle 2.During the process of piston 63 sliding and compressing the paint, positioning plate 64 limits the movement range of piston 63, preventing excessive movement and ensuring accurate paint application with each spray. This cyclical operation allows the operator to continuously apply precise quantities of paint by simply pulling and releasing trigger 5.
