Description

Technical Field

[0001] The present application relates to the technical field of electrical cabinet housing spraying, and in particular to an electrical cabinet housing spraying line. Background Art

[0002] Spray coating of electrical cabinet housings plays a crucial role in the manufacturing process, not only enhancing the product's aesthetics but also enhancing its corrosion and rust resistance, extending its service life. Electrical cabinet housing spray coating methods include electrostatic spraying, powder coating, liquid spraying, and electrophoretic coating. Each method has its own unique characteristics, and the appropriate method can be selected based on specific needs and conditions. Liquid spraying is widely used due to its ease of application, ease of operation, and low cost.

[0003] In order to realize the continuous automatic spraying operation, the electrical cabinet shell spray line is currently used for the shell continuous spraying operation. Its structure is shown in the attached manual. Figure 1 As shown, the system comprises a spray box and a rotating spray rail that passes through the spray box. Hanging rods for suspending the housing are spaced apart on the spray rail, and the housing is provided with hanging holes for the hanging rods. When spraying the housing, the housing is hung on the hanging rods through the hanging holes, and then the spray rails are used to move the housing. Once inside the spray box, several nozzles inside the spray box spray anti-corrosion spray or exterior paint in an all-round manner, completely coating the housing. A drying box (not shown) can also be located behind the spray box for drying.

[0004] like Figure 2-3 As shown, since the hanging rod is inserted into the hanging hole of the shell and the shell is in a hanging state, the upper surface of the hanging hole is in contact with the hanging rod. Therefore, during the spraying process, the hanging rod has a certain contact obstruction on the hanging hole, resulting in the inability to completely spray the anti-corrosion liquid or the outer paint. As a result, when the electrical cabinet is assembled into an outdoor use environment, the part of the shell that has not been completely sprayed will corrode and rust too quickly, causing the outer paint on the shell surface to fall off too quickly, affecting the safety and life of the electrical cabinet. Summary of the Invention

[0005] In response to the above-mentioned problems, the present application aims to provide a spray line for an electrical cabinet shell, which drives the shell upward through a driving component, exposing the hanging hole and its external area, and realizing a complete spraying operation through the spray head in the spray box, thereby solving the current problem of corrosion caused by incomplete spraying due to the hanging obstruction of the shell, and easy peeling of the outer paint.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a spray line for an electrical cabinet shell, comprising a spray box, and a spray guide rail that passes through the spray box and moves in a rotating manner, on which hanging rods for hanging the shell are arranged at intervals, and a hanging hole for passing the hanging rod is provided on the shell, characterized in that a driving component is provided in the spray box to drive the hanging rod to disengage from the hanging hole.

[0007] Preferably, the hanging rod is a V-shaped structure, including a vertical section connected to the spray guide rail and an inclined section, and the inclined section is inserted into the hanging hole.

[0008] Preferably, the driving member is a driving wheel arranged at an oblique interval in the spray box, a driving belt is rotatably sleeved on the driving wheel, and the top end of the driving wheel on the upper side is higher than the bottom surface of the shell.

[0009] Preferably, a limited position section is further extended upwardly at the outer end of the inclined section.

[0010] The beneficial effect of the present application is that a driving component is provided in the spray box to drive the hanging rod to disengage from the hanging hole. The driving component drives the shell (to move upward) so that the hanging hole is disengaged from the hanging rod, thereby leaking the hanging hole and its external area. A complete spraying operation can be achieved through the spray head in the spray box, thereby solving the current problems of corrosion caused by incomplete spraying due to the hanging obstruction of the shell and easy peeling of the outer paint.

[0021] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Refer to the attached Figures 1 to 10 The electrical cabinet housing spray line shown in the figure comprises a spray box 1 and a rotary spray rail 2 that passes through the spray box 1. Hanging rods 4 for suspending housings 3 are spaced apart on the spray rail 2. The housings 3 are provided with hanging holes 3a for the hanging rods 4. The housings are hung on the hanging rods 4 through their hanging holes and then self-propelled by the spray rail 2. Once inside the spray box 1, several nozzles within the spray box spray anti-corrosion spray or exterior paint in an all-around manner, completely coating the housings.

[0023] In order to solve the problem that the shell is blocked due to suspension spraying, and cannot be completely sprayed, which leads to easy corrosion in the later use environment. Figure 5 As shown, the present application provides a driving component in the spray box 1 that drives the hanging rod 4 to disengage from the hanging hole 3a. That is, after the shell 3 is moved to the spray box 1 by the spray guide rail 2 and contacts the driving component, the driving component drives the shell (to move upward), so that the hanging hole 3a is disengaged from the hanging rod 4, and then the hanging hole 3a and its external area are exposed to the outside, and a complete spraying operation can be achieved through the spray head in the spray box 1, thereby solving the current problem of corrosion and easy peeling of the outer paint caused by incomplete spraying due to the hanging obstruction of the shell. After the spray guide rail 2 continues to move the shell 3 and disengages it from the driving component, the hanging hole 3a of the shell 3 contacts the hanging rod 4 again, realizing the hanging effect.

[0024] Specifically, such as Figure 4 As shown, the hanging rod 4 is a V-shaped structure, including a vertical section 41 connected to the spray rail 2 and an inclined section 42, and the inclined section 42 is inserted into the hanging hole 3a. Figure 4As shown, the housing 3 is mounted on the inclined section 42 of the hanging rod 4 through its hanging hole 3a. When the driving member (described later) acts on the housing to drive it upward, the hanging hole 3a moves upward synchronously, thereby releasing the hanging hole 3a from contact with the inclined section 42 (preferably, the outer diameter of the inclined section 42 is smaller than the inner diameter of the hanging hole 3a). After the hanging hole 3a is completely exposed, complete spraying can be achieved within the spray box 1. The hanging hole 3a, which has been released from contact with the inclined section 42, is restricted by the inclined structure of the inclined section 42 to prevent the hanging hole 3a (housing) from falling off.

[0025] Specifically, such as Figure 5-9 As shown, the driving member is a driving wheel 5 arranged at an oblique interval in the spray box 1. A driving belt 6 is rotatably sleeved on the driving wheel 5, and the top of the driving wheel 5 on the upper side is higher than the bottom surface of the shell 3. The working process is as follows: when the shell 3 is moved by the spray guide rail 2 to contact the driving belt 6 at the bottom of the driving wheel 5, the right end of the shell is "lifted" upward along the drive belt 6 and the spray guide rail 2, and then after moving upward, the hanging hole 3a is separated from the contact with the inclined section 42 of the hanging rod 4, and the hanging hole 3a is exposed ( Figure 9 As shown), a complete spraying operation is achieved through the nozzle in the spray box 1.

[0026] As the housing 3 continues to advance, its left end contacts the drive belt 6 and is "lifted" upward by the upper drive wheel 5. This disengages the hanging hole 3a on that side from the inclined section 42 of the hanging rod 4, allowing complete spraying of the hanging hole 3a on that side. The right side of the housing then moves downward, allowing the hanging hole 3a to contact and suspend the hanging rod 4. Thus, after each housing 3 enters the spray box 1 and contacts the drive belt 6, the hanging holes 3a on both sides sequentially disengage from the inclined section 42 of the hanging rod 4, allowing the hanging holes 3a to be exposed, allowing for complete spraying.

[0027] After the housing 3 is driven upward on one side by the driving belt 6, the hanging hole 3a is separated from the inclined section 42 of the hanging rod 4, and the housing 3 is in a non-contact state. In order to avoid the problem of being separated from the inclined section 42 due to the left and right swing in this state, as shown in FIG. Figure 10 As shown, preferably, a limit segment 43 is further extended upwardly at the outer end of the inclined segment 42. When the housing 3 moves upward on one side, the deflection of the housing will contact the limit segment 43 horizontally, thereby limiting the housing 3 from falling off the hanging rod 4.

[0028] The principle of this application is as follows: when spraying the shell, the hanging hole 3a of the shell is fitted over the limiting section 43 and then hung on the inclined section 42, and then the shell is moved by the spray guide rail 2 to realize self-propelled operation. After running into the spray box 1, the multiple nozzles in the spray box can spray anti-corrosion spray or exterior paint in all directions. When the shell 3 is moved by the spray guide rail 2 to contact the drive belt 6 at the bottom drive wheel 5, the right end of the shell is "lifted" upward along the drive belt 6 and the spray guide rail 2, and then after moving upward, the hanging hole 3a is separated from the contact with the inclined section 42 of the hanging rod 4, and the hanging hole 3a is exposed to the outside, and the complete spraying operation is realized through the nozzles in the spray box 1.

[0029] As the housing 3 continues to move, its left end contacts the drive belt 6 and is "lifted" upward by the upper drive wheel 5. This disengages the hanging hole 3a on that side from the inclined section 42 of the hanging rod 4, allowing complete spraying of the hanging hole 3a on that side. The right side of the housing then moves downward, allowing the hanging hole 3a to contact and suspend the hanging rod 4. Thus, each housing 3 can complete the spraying operation upon entering the spray box 1.

[0030] The above shows and describes the basic principles, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, which fall within the scope of this application.
