Description

Technical Field

[0001] This utility model relates to a two-component spraying machine, and more particularly to a high-flow-rate precision screw pump two-component spraying machine. Background Technology

[0002] When operating a current spray painting machine, first connect hoses to both ends of the machine and fill the nuts with lubricating oil; turn off the power, rotate the pressure relief valve downwards, and simultaneously place the suction pipe into a bucket filled with water; then lower the pressure knob, turn the power back on, increase the pressure, allow the fluid to circulate in the return pipe for 15 seconds, and then lower the pressure again; finally, hold the spray gun and slowly apply pressure to spray the object back and forth. Existing spray painting machines are only suitable for spraying one type of material. For two-component spray painting machines, by adding a bucket to hold the other material and a suction pump, two-component spraying can be achieved. However, because the two components have different physical properties, if they cannot be evenly mixed before spraying, the spraying effect will be poor. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a high-flow precision screw pump two-component spraying machine that is reasonably designed, easy to use, and has a good spraying effect, in order to overcome the shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-flow precision screw pump two-component spraying machine is characterized by comprising a support frame and a hopper and screw pump mounted on the support frame. The hopper is divided into a first component material chamber and a second component material chamber by a partition. Suction pipes are provided at the bottom of both the first and second component material chambers. The two suction pipes are connected to the screw pump inlet through a first tee. The screw pump outlet is connected to a spray gun through a hose. A regulating valve for adjusting the discharge volume is installed on the suction pipes. A storage tank is connected to the screw pump outlet. The storage tank is connected to the hose through a second tee. A return pipe for facilitating circulation and mixing is provided between the second tee and the first tee. A control valve is installed at the end of the second tee connected to the hose.

[0006] The technical problem to be solved by this utility model can also be achieved through the following technical solution: a set of walking wheels is installed at the bottom rear of the bracket for easy movement, the walking wheels are symmetrically arranged on both sides of the bracket, and a support leg is installed at the bottom front of the bracket for easy movement.

[0007] The technical problem to be solved by this utility model can also be achieved through the following technical solution: a buffer sleeve is fitted at the bottom end of the support leg to reduce the rigid collision between the support and the ground and better protect the support.

[0008] Compared with existing technologies, this invention improves the two-component coating effect by incorporating a screw pump and a return pipeline to ensure thorough mixing of the raw materials. Furthermore, the inclusion of a storage tank prevents insufficient material supply during spraying, thus enhancing the spraying efficiency of the machine. The high-flow-rate precision screw pump two-component spraying machine described in this invention features a simple principle, reasonable structure, excellent spraying effect, and high spraying efficiency.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0013] Reference Figure 1A high-flow precision screw pump two-component spraying machine includes a bracket 11 and a hopper and a screw pump 5 mounted on the bracket 11. The hopper is divided into a first component material chamber 1 and a second component material chamber 2 by a partition 3. Suction pipes are provided at the bottom of both the first component material chamber 1 and the second component material chamber 2. The two suction pipes are connected to the inlet of the screw pump 6 through a first tee 4. The outlet of the screw pump 6 is connected to a spray gun 10 through a hose 9. A regulating valve 14 for adjusting the output is installed on the suction pipe. A storage tank 6 is connected to the outlet of the screw pump 5. The storage tank 6 is connected to the hose 9 through a second tee 7. A return pipe 8 is provided between the second tee 7 and the first tee 4 to facilitate circulation and mixing. A control valve 15 is installed at the end of the second tee 7 connected to the hose 9. The screw pump, storage tank 6, second tee 7, return pipe 8, and first tee 4 constitute a circulation and mixing structure. In addition, the regulating valve 14 and the control valve 15 are existing products, and the above-mentioned storage tank can also be a small high-pressure storage tank, with the pipes connected by pipe joints.

[0014] A set of wheels 12 for easy movement is installed at the bottom rear of the bracket 11. The wheels 12 are symmetrically arranged on both sides of the bracket 11. A support leg 13 is installed at the bottom front of the bracket 11, and a buffer sleeve is fitted at the bottom of the support leg 13.

[0015] The installation process is as follows: the hopper is connected to the screw pump 5 through the suction pipe and the first tee 4; the outlet of the screw pump 5 is connected to the inlet of the storage tank 6; the storage tank 6 is connected to the hose 9 through the second tee 7; and the return pipe 8 is connected between the second tee 7 and the first tee 4.

[0016] During operation, first close control valve 15. Then, control the opening of the regulating valve according to the ratio of the two different components. Start the screw pump. Under the control of the regulating valve, the two different raw materials are fed into the screw pump 5 through the suction pipe and the first three-way valve 4. They circulate through the storage tank 6, the second three-way valve 7, the return pipe 8, and the first three-way valve 4, undergoing repeated mixing by the screw pump 5. After a period of conveying, close the regulating valve 14 and open control valve 15. Under the pressure in the storage tank 6, hold the spray gun and slowly apply pressure to spray the object back and forth. Because the materials are repeatedly mixed until uniform before spraying by the screw pump, the sprayed material is evenly and appropriately applied, avoiding poor spraying results due to unevenness.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
