[0002] With the increasing use of electrical appliances, voltage transformers are often used. Voltage transformers transform voltage in order to power measuring instruments and relay protection devices, measure the voltage, power and electric energy of the line, or protect valuable equipment, motors and transformers in the line when a line fault occurs. However, the shell of the voltage transformer needs to be sprayed during production, so a shell spraying device for voltage transformer production is needed.

[0003] A Chinese patent application with publication number CN220590502U discloses a shell spraying device for advancer production, including a spray box, a material storage box, and an infusion machine; a spray head is arranged inside the spray box, a material delivery pipe is arranged outside the spray box, the spray head passes through the spray box and is connected to one side of the material delivery pipe, a spray table is arranged at the bottom of the spray box, a rotating motor is arranged at the bottom of the spray box, a rotating rod is arranged on the rotating motor, the rotating rod passes through the spray box and is connected to the spray table, a material storage box is arranged on the back of the spray box, the material storage box is connected to the other end of the material delivery pipe, a liquid collecting box is arranged on the back of the spray box, a liquid collecting hole is arranged at the bottom of the spray box, the liquid collecting hole is connected to the liquid collecting box, a liquid collecting tube is arranged on the liquid collecting box, the liquid collecting tube is connected to the infusion machine, and the infusion machine is connected to the material storage box through the material storage tube; the shell spraying device for advancer production provided by the utility model provides a convenient, safe and environmentally friendly spraying environment.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the above-mentioned shell spraying device for the production of the advancer, the shell is placed on the painting table, which makes it difficult to spray the contact position between the shell and the fixed table, resulting in incomplete spraying and the need for re-painting, which affects the painting efficiency;

[0006] 2. The shell spraying device for the production of the advancer mentioned above needs to be left to air dry after spraying. The paint layer on the shell is not solidified and is inconvenient to remove. It needs to wait for air drying and solidification, which reduces the efficiency of painting.

[0007] To this end, we provide a shell spraying device for voltage transformer production to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to provide a shell spraying device for voltage transformer production.

Hot air is continuously blown to the shell surface by drying components to accelerate the shell curing speed, improve the painting efficiency, and solve the problem that the existing shell spraying device for voltage transformer production has one side that is inconvenient to paint.

[0009] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0011] The utility model is further configured that a motor frame is installed on the right side wall of the paint spray box, the paint spray box is connected to the rotating motor through the motor frame, and the rotating motor is connected to the controller through a wire.

[0012] The utility model is further configured such that the output end of the rotating motor is detachably fixedly connected to the rotating shaft via a coupling, a plurality of fixing springs are circumferentially mounted on the outer side wall of the rotating shaft, and the outer side wall of the rotating shaft is detachably fixedly connected to the fixed end of the fixing spring.

[0013] The utility model is further configured that the moving end of the fixed spring is detachably fixedly connected to the clamping plate, and the surface of the clamping plate is fittedly connected to the rubber pad.

[0014] The utility model is further configured that a plurality of nozzles are arranged above the rotating shaft, a collecting box is installed below the rotating shaft, and a drying box is arranged behind the rotating shaft.

[0015] The utility model is further configured that the lower side wall of the drying box is detachably fixedly connected to the support column, and the lower side wall of the support column is bolted to the paint spray box.

[0016] The utility model is further configured that a motor frame is installed on the inner side wall of the drying box, the drying box is connected to the rotating motor through the motor frame, and the output end of the rotating motor is detachably fixedly connected to the fan.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model sets an installation component. When painting the shell of the power transformer, the clamping plates around the rotating shaft are retracted inward, and the shell is put on. Under the reaction force of the fixed spring, the clamping plates are pushed to spread around to fix shells of different sizes. When the rotating motor is started, the rotating shaft is driven to rotate under the action of the coupling, and the shell is driven to rotate. At the same time, under the action of centrifugal force, the clamping is made more secure, and the upper nozzle is opened to paint the shell, so that the shell can be painted more comprehensively, which solves the problem that when the shell is placed on the painting table, it will make it difficult to spray the contact position between the shell and the fixed table, resulting in incomplete spraying and the need to spray paint again, which affects the painting efficiency.

[0020] 2. The utility model sets a drying component. When spraying paint on the shell, the heating plate and the rotating motor in the drying box are started at the same time. The heating plate works and diffuses the heat evenly into the drying box through the heat conduction plate. Because the fan is set in front of the heating plate and the installed shell is located in front of the fan, after the fan is started, the heat in the drying box will be concentratedly blown to the surface of the shell under the action of reflux, which can speed up the drying speed of the shell surface and improve the drying efficiency, saving costs, and solving the problem that the paint layer on the shell needs to be left to dry after spraying, and it is inconvenient to take it out because it has not been cured and needs to be dried and cured, which reduces the efficiency of painting.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Specific embodiment 1

[0031] See also Figure 1 , Figure 2 and Figure 3 The utility model is a shell spraying device for voltage transformer production, including a paint spraying box 1 and a controller 101 installed on the right side wall of the paint spraying box 1, a collecting box 102 installed on the bottom inner wall of the paint spraying box 1, and the collecting box 102 can collect the sprayed and fallen paint liquid, and a liquid storage tank 103 is installed on the upper side wall of the paint spraying box 1, and the liquid storage tank 103 can store the paint liquid for subsequent painting. A transport pipe 104 is installed at the liquid outlet of the liquid storage tank 103, and the transport pipe 104 has a transportation effect. A plurality of nozzles 105 are installed on the lower side wall of the transport pipe 104, so as to perform a more comprehensive painting treatment with the shell, and a mounting assembly 2 is installed on the inner side wall of the paint spraying box 1, and the mounting assembly 2 can suspend the shell, so as to perform a more comprehensive painting treatment on the shell, thereby solving the problem of incomplete existing painting.

[0032] Specifically, the output end of the rotating motor 201 of the installation component 2 is detachably fixedly connected to the rotating shaft 203 through a coupling 202, and the coupling 202 plays a connecting role. The outer wall of the rotating shaft 203 is circumferentially installed with multiple fixed springs 204, and the fixed springs 204 facilitate the movement of the clamping plate 205. The outer wall of the rotating shaft 203 is detachably fixedly connected to the fixed end of the fixed spring 204 to fix the fixed spring 204. The moving end of the fixed spring 204 is detachably fixedly connected to the clamping plate 205. The surface of the clamping plate 205 is fitted and connected with the rubber pad 206 to achieve integration and synchronous movement. The clamping plate 205 facilitates clamping of the shell, and the rubber pad 206 plays a protective role and increases the friction.

[0033] Furthermore, a motor frame 201a is installed on the right side wall of the paint spray box 1, and the motor frame 201a facilitates the installation of the rotating motor 201. The paint spray box 1 is connected to the rotating motor 201 through the motor frame 201a to fix the rotating motor 201. At the same time, the rotating motor 201 is connected to the controller 101 through a wire to facilitate the control of the start of the rotating motor 201. A plurality of nozzles 105 are arranged above the rotating shaft 203 to facilitate the painting of the shell fixed on the surface of the rotating shaft 203. A collecting box 102 is installed below the rotating shaft 203 to enable the fallen paint liquid to directly enter the collecting box 102. A drying box 301 is arranged behind the rotating shaft 203 to facilitate the drying of the shell.

[0034] The operation process of this embodiment is as follows: when painting the shell of the power transformer, the clamping plates 205 around the rotating shaft 203 are retracted inward, and the shell is put on. Under the reaction force of the fixing spring 204, the clamping plates 205 are pushed to spread around to fix shells of different sizes. When the rotating motor 201 is started, the rotating shaft 203 is driven to rotate under the action of the coupling 202, and the shell is driven to rotate. At the same time, under the action of centrifugal force, the clamping is made more secure, and then the upper nozzle 105 is opened to paint the shell, so that the shell can be more comprehensively painted. Specific embodiment 2

[0036] See also Figure 1 , Figure 2 and Figure 4 On the basis of the specific embodiment 1, a drying component 3 is installed on the inner wall of the paint spraying box 1. The drying component 3 can accelerate the curing speed of the shell surface, solving the problem that the existing curing by air drying reduces the paint spraying efficiency.

[0037] Specifically, a heating plate 302 is installed in the groove of the inner wall of the drying box 301 of the drying component 3, and the heating plate 302 has a heat dissipation effect. The surface of the heating plate 302 is fitted and connected with the heat conducting plate 303, and the heat conducting plate 303 facilitates the uniform transfer of heat into the drying box 301.

The fan 304 is arranged in front of the heating plate 302. The heat generated by the heating plate 302 during operation will be gathered in the drying box 301 and finally discharged from the outlet of the drying box 301. The fan 304 can control the flow direction of the hot air. The lower side wall of the drying box 301 is detachably fixedly connected with the support column 305, and the support column 305 has a supporting effect.

The output end of the rotating motor 201 is detachably fixedly connected to the fan 304 , which facilitates the operation of the fan 304 .

[0039] The operation process of this embodiment is as follows: when spraying paint on the shell, the heating plate 302 and the rotating motor 201 in the drying box 301 are started at the same time, and the heating plate 302 works to diffuse the heat evenly into the drying box 301 through the heat conducting plate 303. Because the fan 304 is arranged in front of the heating plate 302, the installed shell is located in front of the fan 304. After the fan 304 is started, under the action of reflux, the heat in the drying box 301 will be concentratedly blown to the surface of the shell, which can speed up the drying speed of the shell surface, while improving the drying efficiency and saving costs.
