[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1 to 3 , in the embodiments of the present utility model, a flow meter for roll spraying includes an outer shell 1, a connecting handle 2 is fixedly installed at the top of the outer shell 1, an end plate 3 is connected to the front end of the outer shell 1, and a flow rate mechanism is distributed inside the outer shell 1 and on the end plate 3.

[0017] In this embodiment: In the roll spraying process, it is necessary to adjust the spraying speed of the spray gun to avoid the phenomenon of excessive or insufficient spraying. Therefore, before spraying, the input pipe of the spray gun is connected to the flow rate mechanism. After observing the changes in the flow rate mechanism and adjusting the speed of the spray gun to an appropriate speed, the workpiece is then roll sprayed.

[0018] Please pay special attention to referring to Figure 1 , Figure 2 and Figure 3, the flow rate mechanism includes a glass tube 7 with a hollow structure and open tops and bottoms. The bottom end of the glass tube 7 is connected to a three-way pipe 8 through a connecting pipe. A valve 9 is installed on the branch of the three-way pipe 8 connected to the glass tube 7. The output branch of the three-way pipe 8 is connected to a spray gun through a pipe. Inside the housing 1, a glass material tube 6 is installed on one side of the glass tube 7. The top of the glass material tube 6 is open, and a discharge nozzle is installed at the bottom end of the glass material tube 6. The discharge nozzle is connected to another branch of the three-way pipe 8 through a pipe. A valve 9 is installed on the other branch of the three-way pipe 8. The flow rate mechanism further includes a first visible slot 5 opened on one side of the end face of the end plate 3. The first visible slot 5 is aligned with the glass tube 7. Scales 10 are engraved on both sides of the first visible slot 5 on the end face of the end plate 3.

[0019] In this embodiment: Connect the input end of the spray gun to the output pipe branch of the three-way pipe 8. Then, first open the valve 9 connected to the glass tube 7. At this time, the spraying medium in the glass tube 7 is sucked out and sucked out through the spray gun. Observe the liquid level change of the spraying medium in the glass tube 7 through the first visible slot 5, and judge the discharge amount of the spraying medium per unit time according to the scale 10, then the spraying speed of the spray gun can be calculated. After the speed is adjusted, the running speed of the micro pump on the spray gun is no longer adjusted. Then, close the valve 9 connected to the glass tube 7 and open the valve 9 connected to the glass material tube 6. At this time, the spraying medium in the glass material tube 6 is sprayed onto the workpiece inside the roller spraying machine through the spray gun. And during the working process of the spray gun, the spraying speed of the spray gun can be observed at any time by switching the valve 9 in the above way, and correction can be made at any time without stopping the machine operation;

[0020] Since the tops of the glass tube 7 and the glass material tube 6 are both open, the spraying medium can be added through their top openings.

[0021] Please refer specifically to Figure 1 and Figure 2 , a second visible slot 4 aligned with the glass material tube 6 is opened at one end of the housing 1, and a connection port 11 aligned with the three-way pipe 8 is opened at one end of the housing 1.
