Description

Technical Field

[0001] This utility model relates to the field of powder coating supply pipe technology, specifically a powder coating supply pipe structure. Background Technology

[0002] Powder coating is a process in which powder coating is applied to the surface of a workpiece using powder spraying equipment. Under the action of electrostatics, the powder will be evenly adsorbed onto the surface of the workpiece to form a powdery coating. The powdery coating is then baked at high temperature to level and cure, resulting in a final coating with different effects. The coating effect of powder coating is superior to that of spray painting in terms of mechanical strength, adhesion, corrosion resistance, and aging resistance, but the cost is higher than that of spray painting.

[0003] For example, patent document CN 212681383 U discloses a paint supply device for a spray painting equipment, including a base. A paint storage tank is installed on the upper side of one end of the base, and an upper bracket is installed on the upper side of the other end of the base. A first pump body and a second pump body are installed on the upper side of the upper bracket. One end of the first pump body and the second pump body are connected to a suction pipe, and one end of the suction pipe is connected to the bottom of the paint storage tank. The discharge end of the first pump body and the second pump body are both equipped with a discharge pipe, one end of which is connected to a paint supply pipe. Multiple paint supply connectors are installed on one side of the paint supply pipe. This utility model uses two pump bodies to supply one paint storage tank, which is convenient for simultaneously providing a certain air pressure for spraying multiple spray guns, which is beneficial to improving the efficiency of spraying and can avoid the large amount of paint residue caused by using two paint storage tanks, thus facilitating energy saving.

[0004] However, in actual use, this structure can only be used for simple powder coating operation. The powder material cannot be continuously and evenly extracted, which easily leads to intermittent spraying at the nozzle, affecting the powder coating effect of the equipment. At the same time, the equipment cannot perform more efficient pressurization operation, affecting the powder coating effect and failing to meet daily use needs. Therefore, it is urgent to design a powder coating supply pipeline structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a powder coating supply pipeline structure to solve the problems mentioned in the background art. In actual use, the existing structure can only be used for simple powder coating operation. However, the powder material cannot be continuously and evenly extracted, which easily leads to intermittent spraying at the nozzle, affecting the powder coating effect of the equipment. At the same time, the equipment cannot perform more efficient pressurization operation, affecting the powder coating effect and failing to meet the daily use needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a powder coating supply pipeline structure, including a material control tube frame, a flow passage tube frame fixedly connected to the center of the surface of the material control tube frame, a conical tube frame fixedly connected to the top of the flow passage tube frame, and an infusion tube fixedly connected to the top of the conical tube frame;

[0007] A first material pump and a second material pump are fixedly connected to one side of the material control tube frame, and a second material pump is fixedly connected to the other side of the material control tube frame. A material extraction base frame is fixedly connected to the bottom of the first material pump and the second material pump.

[0008] Preferably, the material extraction base frame has material conveying pipe grooves on both sides, and a filter screen is provided at the bottom of the material extraction base frame.

[0009] Preferably, a pressure valve seat is provided at the center of the material extraction base frame, and a pressure pump is provided on the side of the pressure valve seat.

[0010] Preferably, the inner wall of the material control tube frame is provided with a liquid control tank frame, and a central inner tank is provided at the center of the liquid control tank frame.

[0011] Preferably, the liquid control tank frame has side inner tanks on both sides, the inner walls of the side inner tanks have side flow channels, and the inner bottom wall of the central inner tank has a confluence channel.

[0012] Preferably, a flow grille is provided on the top of the central inner liner.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This powder coating supply pipeline structure, through the inclusion of a material control frame, flow passage frame, conical frame, liquid delivery pipe, liquid control tank frame, central inner tank, side inner tanks, side flow channels, a confluence channel, and a flow grid, enables smoother powder supply operations and ensures consistent powder output. In practical use, the operator first installs the material control frame on top of the powder storage tank. Then, the powder is drawn in from both ends of the side inner tanks on either side of the liquid control tank frame. The powder drawn into the side inner tanks flows through the side flow channels on the bottom wall to the confluence channel on the bottom wall of the central inner tank. From there, it is discharged through the flow grid to the flow passage frame, conical frame, and liquid delivery pipe. The continuous input of powder coating from the two side inner tanks to the central inner tank significantly improves the stability of the powder coating supply, demonstrating the practicality of the equipment design.

[0015] This powder coating supply pipeline structure, through the inclusion of a control pipe frame, a first and second pump, a base frame, a conveying trough, a filter screen, a pressure valve seat, and a pressure pump, further enhances the overall performance of the equipment. During daily use, operators can movably install the first and second pumps at both ends of the control pipe frame and place the filter screen at one end of the base frame into the storage tank. Starting the first and second pumps allows powder to be drawn from the filter screen, flowing along the conveying trough into both ends of the control pipe frame. Simultaneously, the pressure pump can be activated to pressurize the central inner liner of the control pipe frame through the pressure valve seat, ensuring a consistently stable pressurized supply within the central liner. This demonstrates the comprehensive design of the equipment. Attached Figure Description

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.

[0023] A powder coating supply pipeline structure includes a material control frame 1, a flow passage frame 2 fixedly connected to the center of the surface of the material control frame 1, a conical frame 3 fixedly connected to the top of the flow passage frame 2, a liquid delivery pipe 4 fixedly connected to the top of the conical frame 3, a liquid control tank frame 12 provided on the inner wall of the material control frame 1, a central inner tank 13 provided at the center of the liquid control tank frame 12, side inner tanks 14 provided on both sides of the liquid control tank frame 12, side flow passage grooves 15 provided on the inner wall of the side inner tanks 14, a flow collection groove 16 provided on the bottom wall of the central inner tank 13, and a flow passage grid 17 provided on the top of the central inner tank 13. The powder coating is collected and discharged from the flow passage grid 17 of the flow passage groove 16 to the flow passage frame 2, the conical frame 3 and the liquid delivery pipe 4. The two sets of side inner tanks 14 continuously input powder coating into the central inner tank 13, thereby greatly improving the continuous stability of the powder coating supply of the equipment.

[0024] The first material pump 5 and the second material pump 6 are fixedly connected to one side of the material control tube frame 1, and the second material pump 6 is fixedly connected to the other side of the material control tube frame 1. The bottom ends of the first material pump 5 and the second material pump 6 are fixedly connected to the material extraction base frame 7. The material extraction base frame 7 has material conveying pipe grooves 8 on both sides. The bottom end of the material extraction base frame 7 is equipped with a filter screen 9. The center of the material extraction base frame 7 is equipped with a pressure valve seat 10. The side of the pressure valve seat 10 is equipped with a pressure pump 11. The pressure pump 11 can be started synchronously to pressurize the central inner liner 13 inside the liquid control liner frame 12 from the pressure valve seat 10, so that the central inner liner 13 is always under stable pressure and material conveying operation.

[0025] Working Principle: During operation, the operator first installs the control tube frame 1 onto the box storing the paint powder. Then, the paint powder is drawn in from both ends of the side inner liner 14 on either side of the liquid control liner 12 on the inner wall of the control tube frame 1. The paint powder drawn into the side inner liner 14 flows from the side flow channel 15 on the inner bottom wall into the confluence channel 16 on the inner bottom wall of the central inner liner 13. Then, it flows from the flow grid 17 of the confluence channel 16 to the flow tube frame 2, the conical tube frame 3, and the liquid delivery pipe 4 for discharge. The two sets of side inner liner 14 continuously input powder paint into one set of central inner liner 13, thus greatly improving the continuous stability of the powder paint supply. During use, the operator can movably install the first material pump 5 and the second material pump 6 at both ends of the material control tube frame 1, and place the filter screen 9 at one end of the material extraction base frame 7 into the storage tank. Normally, starting the first material pump 5 and the second material pump 6 will suck out powder from the filter screen 9. The powder enters both ends of the material control tube frame 1 along the conveying pipe groove 8. At the same time, the pressurizing pump 11 can be started synchronously to pressurize the central inner liner 13 inside the liquid control liner frame 12 from the pressurizing valve seat 10, so that the central inner liner 13 is always under stable pressure for material conveying. The above is the complete working principle of this utility model.
