Description

Technical Field

[0001] This utility model relates to the field of spraying machine technology, and in particular to a reciprocating automatic spraying machine. Background Technology

[0002] A spray painting machine is a specialized coating equipment that uses spraying technology. The principle is to control the airflow to instantly push the air distribution reversing device to reverse, thereby causing the piston of the pneumatic motor to make a stable and continuous reciprocating motion, which pressurizes the inhaled paint. The paint is then transported to the spray gun of the spray painting machine through a high-pressure hose, and the spray gun instantly atomizes the paint and releases it onto the surface of the object being coated.

[0003] Chinese Patent No. CN209379276U discloses an automatic reciprocating spraying machine. This utility model is easy to use, has the function of removing dust from the surface of workpieces, and can effectively purify exhaust gas, making it suitable for widespread promotion and use.

[0004] In the aforementioned patent documents, when painting parts, a small amount of paint is sprayed onto the worktable. In the prior art, it is impossible to effectively recycle the paint, resulting in waste. Summary of the Invention

[0005] The purpose of this utility model is to solve the following shortcomings in the existing technology: when spraying parts, a small amount of paint will be sprayed onto the operating table. In the existing technology, it is not possible to effectively recycle the paint, thus causing waste. Therefore, a reciprocating automatic spraying machine is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reciprocating automatic spraying machine includes an operating table, on which a bracket is fixedly installed, and spraying equipment is installed on the bracket;

[0008] The operating platform has multiple trapezoidal grooves horizontally formed, with one end of each trapezoidal groove extending to one side of the operating platform. A collection trough is installed on one side of the operating platform, and multiple mounting holes, each connected to a trapezoidal groove, are formed on the other side of the operating platform. Gas nozzles are fixedly installed in each of the multiple mounting holes, and an air jet assembly for spraying gas onto the multiple gas nozzles is provided on the side of the operating platform.

[0009] Preferably, the jet assembly includes an air pump fixedly installed on the side of the control panel and a connecting pipe fixedly installed at the output end of the air pump, with one end of each of the plurality of gas nozzles connected to the connecting pipe.

[0010] Preferably, the operating table is symmetrically fixedly mounted with support frames on its side, and the collection trough is placed on the two support frames, with one side of the collection trough in contact with the side of the operating table.

[0011] Preferably, a diaphragm is fixedly installed on the inner wall of the trapezoidal groove, and the diaphragm is made of a high-temperature resistant material.

[0012] Preferably, the operating table has an installation cavity, a metal heating plate is fixedly installed in the installation cavity, a power-conducting wire is fixedly installed on the side of the metal heating plate, a power supply is fixedly installed on the side of the operating table, and one end of the power-conducting wire passes through the installation cavity and is connected to the power supply.

[0013] Preferably, the surface of the metal heating plate is in contact with the inner wall of the mounting cavity, and the metal heating plate is a copper-zinc alloy.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Paint not sprayed on the parts will enter multiple trapezoidal grooves. Then, through the cooperation of the jet assembly and gas nozzle, the paint collected in the trapezoidal grooves will be blown towards the collection tank and collected in the collection tank, which can effectively recycle paint and reduce paint waste.

[0016] 2. The metal heating plate will heat up after being powered on, thereby raising the surface temperature of the workbench, preventing the paint in the trapezoidal groove from solidifying, and making it easier for the paint to flow into the collection tank for collection.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A reciprocating automatic spraying machine includes an operating table 1, a bracket 2 fixedly installed on the operating table 1, a spraying device 3 installed on the bracket 2, the spraying device 3 is installed on the bracket 2 and can move back and forth on the bracket 2 to achieve spraying of parts.

[0025] Multiple trapezoidal grooves 4 are horizontally opened on the operating table 1. One end of the multiple trapezoidal grooves 4 extends to one side of the operating table 1. A collection trough 5 is installed on one side of the operating table 1. Multiple mounting holes, all connected to the trapezoidal grooves 4, are opened on the other side of the operating table 1. Gas nozzles 6 are fixedly installed in the multiple mounting holes. An air jet assembly for spraying gas to the multiple gas nozzles 6 is provided on the side of the operating table 1. The air jet assembly includes an air pump 7 fixedly installed on the side of the operating table 1 and a connecting pipe 8 fixedly installed at the output end of the air pump 7. One end of each of the multiple gas nozzles 6 is connected to the connecting pipe 8.

[0026] Multiple trapezoidal slots 4 are provided on the operating table 1. When the parts are being sprayed, they are placed on the operating table 1 with the trapezoidal slots 4 located directly below the parts. During the spraying process, the paint not sprayed on the parts will enter the trapezoidal slots 4. At the same time, the air pump 7 is started, and gas is injected into multiple gas nozzles 6 through the connecting pipe 8. One end of the gas nozzle 6 is horizontally facing the trapezoidal slot 4, so the gas sprayed from the gas nozzle 6 will be blown horizontally into the trapezoidal slot 4. At this time, the gas will blow the paint collected in the trapezoidal slot 4 towards the collection tank 5 and flow into the collection tank 5, which can effectively recover the paint and reduce paint waste.

[0027] Support frames 9 are symmetrically fixed on the side of the operating table 1. The collection tank 5 is placed on the two support frames 9, with one side attached to the side of the operating table 1. The collection tank 5 is installed on the operating table 1 through the support frames 9 to ensure that when the paint flows out from one end of the trapezoidal groove 4, it can flow into the collection tank 5. When the collection tank 5 is full of paint, the collection tank 5 can be removed for easy recycling.

[0028] A diaphragm is fixedly installed on the inner wall of the trapezoidal groove 4. The diaphragm is made of high temperature resistant material and can ensure the smoothness of the inner wall of the trapezoidal groove 4, which facilitates the flow of paint in the trapezoidal groove 4.

[0029] An installation cavity is provided inside the operating table 1. A metal heating plate 10 is fixedly installed inside the installation cavity. A power supply wire 11 is fixedly installed on the side of the metal heating plate 10. A power supply 12 is fixedly installed on the side of the operating table 1. One end of the power supply wire 11 passes through the installation cavity and is connected to the power supply 12. The surface of the metal heating plate 10 is in contact with the inner wall of the installation cavity. The metal heating plate 10 is made of copper-zinc alloy.

[0030] The metal heating plate 10 is powered by the power supply 12 and the power-carrying wire 11, which raises the surface temperature of the metal heating plate 10. At the same time, the temperature of the surface of the metal heating plate 10 is transferred to the operating table 1, raising the surface temperature of the operating table 1. This prevents the paint in the trapezoidal groove 4 from solidifying and facilitates the flow of the paint into the collection tank 5, making it easier to collect.

[0031] In this invention, multiple trapezoidal grooves 4 are formed on the operating table 1. When the part is being sprayed, it is placed on the operating table 1, with the multiple trapezoidal grooves 4 located directly below the part. During the spraying process, the paint not sprayed on the part will enter the multiple trapezoidal grooves 4. At the same time, the air pump 7 is started, and gas is injected into multiple gas nozzles 6 through the connecting pipe 8. One end of the gas nozzle 6 is horizontally facing the trapezoidal groove 4, so the gas sprayed from the gas nozzle 6 will be blown horizontally into the trapezoidal groove 4. At this time, the gas will blow the paint collected in the trapezoidal groove 4 towards the collection tank 5 and flow into the collection tank 5, which can effectively recover the paint and reduce paint waste.
