Description

Technical Field

[0001] This utility model relates to the field of frequency converter manufacturing technology, specifically a painting device for frequency converter manufacturing. Background Technology

[0002] A frequency converter is a power electronic device that achieves precise control of a motor's speed and torque by changing the frequency and voltage of the power supply input to the motor. It is widely used in industrial automation, energy management, transportation, and other fields, and is a core device for achieving energy saving, speed regulation, and intelligent control in modern industry.

[0003] The prior art discloses an engineering painting device (publication number CN205995665U), comprising a cylinder, a paint extraction pump, and a base. The cylinder contains a rotating shaft with evenly distributed blades. A heating tube is installed on the inner wall of the cylinder, and a temperature sensor is located at the lower end of the heating tube. A motor is fixedly connected to the upper end of the cylinder via a bracket. A liquid level sensor is located on the inner side of the bottom of the cylinder, and an alarm is located on the outer side of the bottom of the cylinder. The paint extraction pump is sealed to one side of the cylinder via an iron pipe, and the paint extraction pump is connected to a high-pressure nozzle via a spray pipe. This invention, through the matching configuration of the paint extraction pump, the speed-regulating motor, and the frequency converter, ensures a stable and uninterrupted output of paint. The high-pressure nozzle atomizes the paint and sprays it evenly onto the object surface. The rotating shaft with blades ensures thorough mixing and agitation of the paint and rosin added to the cylinder.

[0004] The cylinder has a base at the bottom. The cylinder is used for spraying paint for a long time, but the paint adheres to the inner wall surface of the cylinder, so the inner wall surface of the cylinder needs to be cleaned. Cleaning the inner wall surface of the cylinder requires disassembling the entire cylinder, which makes the replacement of the cylinder troublesome and time-consuming. Utility Model Content

[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. 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.

[0024] Please see Figure 1-4 The present invention provides the following technical solution:

[0025] A painting device for frequency converter production includes a painting device 1 and a support base 3. A support frame 2 is welded to the right side surface of the support base 3, and the support base 3 is installed on the bottom surface of the painting device 1.

[0026] The spraying device 1 includes a mixing tank 11, a pump 12 is bolted to the bottom of the mixing tank 11, a spray nozzle 14 is installed on the left side surface of the pump 12, a limiting component 13 is installed inside the mixing tank 11, and support columns 15 are installed at the front and rear ends of the limiting component 13. The mixing tank 11 is bolted to the top surface of the bearing base 3, and the support columns 15 are bolted to the top surface of the bearing base 3, so as to facilitate the disassembly and replacement of the mixing tank 11 and the support columns 15.

[0027] The limiting component 13 includes a connecting post 131, which is movably connected to the top surface of the support post 15. The connecting post 131 and the support post 15 are connected, making it easy to disassemble and replace the connecting post 131 and use connecting posts 131 of different specifications.

[0028] A clamping block 132 is installed on the surface of the connecting column 131. The clamping block 132 is movably connected to the surface of the mixing tank 11. The clamping block 132 clamps and fixes the mixing tank 11, making it easy to disassemble and replace the mixing tank 11. The clamping block 132 stabilizes the mixing tank 11, making the spraying of the frequency converter more convenient.

[0029] The clamping block 132 has a fastening threaded rod 133 welded inside. There are two sets of clamping blocks 132, which are distributed vertically. The upper set of clamping blocks 132 is threaded to the bottom surface of the connecting column 131, the lower set of clamping blocks 132 is threaded to the bottom of the support column 15, and the lower set of clamping blocks 132 is movably connected to the top surface of the bearing base 3.

[0030] A limiting plate 134 is threadedly connected to the top surface of the connecting column 131. A limiting cover plate 139 is connected to the bottom surface of the limiting plate 134. A variable frequency motor 136 is bolted to the middle position of the limiting cover plate 139. A stirring rod 137 is bolted to the bottom surface of the variable frequency motor 136. The limiting cover plate 139 is bolted to the top surface of the mixing tank 11. The connection between the limiting cover plate 139 and the mixing tank 11 determines the position of the variable frequency motor 136 and the stirring rod 137, making it convenient to disassemble and replace the variable frequency motor 136 and the stirring rod 137.

[0031] The top surface of the limiting cover plate 139 is welded with a feed pipe 138, and the top of the connecting column 131 is threaded with a fastening bolt 135. The fastening bolt 135 is threaded to the front and rear ends of the limiting plate 134. The fastening bolt 135 locks and fixes the connecting column 131 and the limiting plate 134, making it easy to disassemble and replace the limiting plate 134, maintain the stability of the mixing tank 11, and facilitate the spraying operation of the frequency converter.

[0032] When in use, rotate the fastening bolt 135 to loosen the connection between the limiting plate 134 and the connecting column 131, pull the limiting plate 134 upward, and the limiting plate 134 will disengage from the limiting cover plate 139 and the connecting column 131.

[0033] Next, rotate the nut to disengage it from the fastening threaded rod 133, thus loosening the connection between the fastening threaded rod 133, the connecting post 131, and the support post 15.

[0034] Pull the clamping block 132 outwards, and the clamping block 132 will drive the fastening threaded rod 133 to move outwards, so that the fastening threaded rod 133 will disengage from the connecting column 131 and the support column 15, and at the same time the clamping block 132 will disengage from the surface of the mixing tank 11.

[0035] Then pull the mixing tank 11 to move it, so that the mixing tank 11 is separated from the support base 3, and turn the nut to loosen the connection between the limit cover plate 139 and the mixing tank 11.

[0036] Pull the limiting cover 139 upwards. The limiting cover 139 drives the variable frequency motor 136 and the stirring rod 137 upwards, allowing the stirring rod 137 to detach from the mixing tank 11, facilitating the rinsing of the inside of the mixing tank 11. At the same time, the stirring rod 137 and the limiting cover 139 are rinsed to keep the mixing tank 11, the stirring rod 137 and the limiting cover 139 clean. After rinsing, the mixing tank 11, the limiting cover 139 and the stirring rod 137 are reassembled.

[0037] The position of the mixing tank 11 is limited by the clamping block 132, the connecting column 131, the support column 15 and the limiting plate 134.

[0038] Paint is poured into the feed pipe 138, and then the variable frequency motor 136 is started. The rotor of the variable frequency motor 136 drives the stirring rod 137 to rotate. The stirring rod 137 stirs and mixes the paint inside the mixing tank 11, which can form the desired paint color.

[0039] The extraction pump 12 extracts the paint that has been mixed inside the mixing tank 11, and then sprays it onto the frequency converter through the spray nozzle 14.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
