Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a jet mixing device with base surface spacing adjustment and flow monitoring. Background Art

[0002] The application of a two-component coating involves spraying and mixing two components. This involves mixing the two components of the coating (which can be a resin base and a curing agent, or other components) during the spraying process. This chemical reaction occurs, forming a hard coating film. When a worker uses a sprayer to apply the coating, the two components are ejected from two separate nozzles, positioned roughly on the same plane, to ensure thorough mixing.

[0003] To improve paint spraying quality, the nozzles for the two components need to be kept at a certain distance from the ground to ensure thorough mixing during the spraying process. Uneven mixing of the two components can lead to poor adhesion and premature aging. However, when spraying paint with a handheld spray gun, it is difficult for workers to control the distance between the nozzle and the ground, which affects the mixing of the two components and the spray quality.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] Example 1

[0037] The present application discloses a spray mixing device with base surface spacing adjustment and flow monitoring. Figure 1 and Figure 2 The spray mixing device with base surface spacing adjustment and flow monitoring includes a spray gun 1, a delivery pipe 2, a flow meter 3 and a mobile cart 4.

[0038] Reference Figure 1 Spray gun 1 is connected to an external sprayer via delivery pipe 2. Spray gun 1 is equipped with two nozzles for spraying the two components of the paint. Flow meter 3 is fixed to delivery pipe 2 to monitor the flow rate of delivery pipe 2, allowing staff to observe the spraying amount of the two paint components and ensure the required thickness of the building floor paint is sprayed.

[0039] Reference Figure 1 and Figure 2 The mobile cart 4 includes a frame 41, universal wheels 42, a counterweight 43 and a cylinder 44. There are a plurality of universal wheels 42, and the plurality of universal wheels 42 are located on the same horizontal plane. The universal wheels 42 are fixedly connected to the frame 41. At least two cylinders 44 are provided, and the plurality of cylinders 44 are fixedly connected to the frame 41 at intervals. In this embodiment, two cylinders 44 are provided, and the two cylinders 44 are located on the same plane; in other embodiments, the cylinders 44 can also be provided at an acute angle. The counterweight 43 is fixedly provided on the side of the frame 41 close to the ground; so as to improve the stability of the movement of the mobile cart and reduce the risk of the mobile cart 4 tipping over.

[0040] Reference Figure 1 and Figure 2In this embodiment, handles 411 are provided on both sides of the frame 41 for the staff to grasp, thereby facilitating the staff to push the mobile cart 4. In this embodiment, the spray gun 1 is arranged between the two handles 411, and the spray gun 1 is detachably connected to the frame 41. The mobile cart 4 is used to fix the height of the spray gun 1, so that the nozzle of the spray gun 1 maintains a certain distance from the ground. In this embodiment, the spray gun 1 is fixed to the frame 41 by plugging it into the barrel 44; in other embodiments, the spray gun 1 and the frame 41 can be detachably connected by means of magnetism or the like. Specifically, the spray gun 1 is provided with plug-in columns 11, and the number of plug-in columns 11 is consistent with the number of barrels 44, and the plug-in columns 11 are plugged into the barrel 44. Therefore, the staff can conveniently install the spray gun 1 on the mobile cart 4 by plugging and fixing the plug-in columns 11 to the barrel 44. The staff moves the spray gun 1 by pushing the mobile cart 4, so that the distance between the nozzle of the spray gun 1 and the ground remains unchanged during the movement of the spray gun 1. After the two components of the paint are sprayed from the nozzle of the spray gun 1, they can be fully mixed and reacted in the air to improve the spraying quality of the paint.

[0041] When the spray gun 1 is held at a short distance from the ground, the two components of the paint are difficult to fully mix and react in mid-air. However, when the spray gun 1 is held at a long distance from the ground, the two components of the paint tend to disperse, affecting the adhesion strength between the paint and the ground, as well as the thickness of the applied paint. In this embodiment, the distance between the nozzle of the spray gun 1 and the ground is 60-80 cm, ensuring that the two components of the paint can fully mix and react in mid-air while also ensuring a sufficient application thickness and adhesion strength.

[0042] Reference Figure 1 and Figure 2 , the diameter of the plug-in column 11 decreases along the direction away from the spray gun 1; the inner diameter of the cylinder 44 increases along the direction away from the frame 41; the outer peripheral wall of the plug-in column 11 abuts against the inner peripheral wall of the cylinder 44; thus, through the cooperation between the plug-in column 11 and the cylinder 44, the stability of the spray gun 1 after being fixed can be improved.

[0043] Example 2

[0044] The difference between this embodiment 2 and embodiment 1 is that:

[0045] Reference Figure 3 and Figure 4The mobile cart 4 also includes a serpentine tube 5. The number of serpentine tubes 5 matches the number of barrels 44. One end of the serpentine tube 5 is fixedly connected to the frame 41, and the other end is fixedly connected to the barrel 44. The serpentine tube 5 is a metal hose, and the operator can bend the serpentine tube 5 to change its shape. In this embodiment, the two ends of the serpentine tube 5 are respectively fixed to a first mounting plate 7 and a second mounting plate 8. The first mounting plate 7 is welded to the barrel 44, and the second mounting plate 8 is fixed to the frame 41 by bolts. Thus, by bending the serpentine tube 5, the operator can adjust the height and tilt angle of the barrel 44, that is, the operator can adjust the height and tilt angle of the spray gun 1 to improve the spray quality of the paint.

[0046] Example 3

[0047] The difference between this embodiment 3 and embodiment 1 is that:

[0048] Reference Figure 5 and Figure 6 The mobile cart 4 also includes a fastener 6, which is connected to the frame 41. The fastener 6 is used to fix the conveying pipe 2. In this embodiment, the fastener 6 includes a curved plate 61, a connecting ear plate 62 and a flexible pad 63; the connecting ear plate 62 is provided on both sides of the curved plate 61, and the connecting ear plate 62 and the curved plate 61 are integrally formed. The connecting ear plate 62 is used to be bolted to the frame 41. The curved plate 61 is provided with a groove for accommodating the conveying pipe 2. The flexible pad 63 is fixed to the side of the curved plate 61 close to the frame 41. The flexible pad 63 is used to abut against the conveying pipe 2. By providing the flexible pad 63 between the curved plate 61 and the conveying pipe 2, the fixing effect of the fastener 6 and the frame 41 on the conveying pipe 2 can be improved. The flexible pad 63 can be a flexible material such as a rubber pad, a silicone pad, etc.

[0049] When the connecting ear plate 62 is bolted to the frame 41, the arc plate 61 and the frame 41 are forced to clamp the delivery pipe 2, thereby fixing the delivery pipe 2 to the mobile cart 4; thereby, during the movement of the mobile cart 4, the interference of the delivery pipe 2 on the position of the spray gun 1 can be reduced, thereby improving the stability of the operation of the injection mixing device.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
