Detailed implementation manners

[0029] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0030] As Figure 1 、 Figure 2 shown, a side spraying shielding device for metal coils includes a driving wheel device 3 and a driven wheel device 2 installed on the left and right sides of the bracket 1. The driving wheel device 3 is connected to the driven wheel device 2 through a synchronous belt 4, and the synchronous belt 4 is connected to a power source.

[0031] Place this device on both sides of the coil or sheet, energize the synchronous belt 4. The synchronous belt 4 is designed by combining Faraday's principle and the principle of no powder deposition in the physical shielding dead angle to ensure the reduction of edge discharge phenomenon during normal painting. The main content of Faraday's law of electromagnetic induction is that when the magnetic flux of a loop changes, the magnitude of the induced electromotive force in the loop is proportional to the rate of change of the magnetic flux passing through the loop. When there is dust adhered to the synchronous belt 4, the powder spraying on the synchronous belt 4 is recycled or recycled through the rotation of the driving wheel device 3 or the driven wheel device 2 to achieve the purpose of cleaning, ensuring the surface leveling effect and aesthetics; reducing energy consumption while saving costs and protecting the environment. During the painting process, the powder spraying is effectively controlled without overflow, and at the same time, the phenomenon of back mixing is avoided.

[0032] As Figure 4 shown, the driving wheel device 3 includes a motor 31, a motor main shaft 32 and a driving wheel 33. One end of the motor main shaft 32 is connected to the motor 31, and the other end is connected to the driving wheel 33. The motor 31 is installed in the motor mounting seat 313, and the motor mounting seat 313 is fixedly connected to the bracket 1 through the mounting seats 38 on the front and rear sides. The motor 31 drives the driving wheel 33 on the motor main shaft 32 to rotate, and the driving wheel 33 drives the driven wheel 23 to rotate through the synchronous belt 4. Before painting, the speed of the driving motor 31 is set according to the process. The driving wheel 33 drives the shielding belt to operate through the driving of the motor 31, completely solving the problems of thick edges and back paint mixing caused by tip discharge during the painting process. The shielded powder falls in the powder booth and is immediately recycled for secondary use.

[0033] As Figure 4 、 Figure 6 shown, one end of the motor main shaft 32 is connected to the motor 31, and a speed reducer 34 is provided at the other end. The speed reducer 34 is connected to the motor 31 through a universal joint 314 for lathe. The operation of the speed reducer 34 is driven by the motor 31 to ensure the stability of the synchronous belt 4.

[0034] As Figure 3 、 Figure 5 、 Figure 11 shown, a ball screw sleeve A 36 is provided on one side of the motor mounting seat 313. A ball screw A 35 is provided on the ball screw sleeve A 36. The ball screw A 35 is located below the motor 31 and penetrates through the motor mounting seat 313 and the mounting seat 38 respectively. A second bearing mounting seat 39 is fixedly connected to the mounting seat 38. A second rolling bearing 310 that is movably connected to the ball screw A 35 is provided on the second bearing mounting seat 39. One end of the ball screw A 35 is provided with a handle A 311 or a motor A 316, and a retaining piece is provided at the other end. The ball screw A 35 is shaken by the handle A 311 or the motor A 316 to adjust the ball screw sleeve A 36 to drive the driving wheel device 3 to move back and forth, thereby adjusting the distance between the synchronous belt 4 and the edge of the coil or sheet. Automatic operation is achieved through the motor A 316, effectively saving labor costs and improving production efficiency.

[0035] As Figure 4 shown, on both the left and right sides of the ball screw A 35, there are driving guide shafts 37 penetrating through the motor mounting base 313. On one side of the motor mounting base 313, there is a flanged linear bearing A 312 movably connected to the driving guide shaft 37. The front and rear ends of the driving guide shaft 37 are fixedly connected to the front and rear mounting seats 38. The driving guide shaft 37 effectively controls the stable forward and backward movement of the driving wheel device 3.

[0036] As Figure 3 、 Figure 6 shown, above the driving wheel 33, there is a protective cover A 315, and on the protective cover A 315, there is a groove through which the synchronous belt 4 passes. The protective cover A 315 effectively ensures the cleanliness of the surface covered for a long time during painting. By using the principles of Faraday electromagnetic induction and physical shielding, it avoids the powder hanging design of the transmission device during long-term shielding, ensures the stability of the transmission, and shields the driving wheel 33 on the back of the shielding belt.

[0037] As Figure 8 shown, the driven wheel device 2 includes a driven wheel support 21, a driven shaft 22, and a driven wheel 23. The driven wheel 23 is connected to the driven wheel support 21 through the driven shaft 22, and the driven wheel support 21 is fixedly connected to the bracket 1 through the driven wheel mounting base 27.

[0038] As Figure 8 、 Figure 10 、 Figure 12 shown, on the driven wheel support 21, there is a ball screw sleeve B 25, and on the ball screw sleeve B 25, there is a ball screw B 24. The ball screw B 24 penetrates through the driven wheel support 21 and the driven wheel mounting base 27 respectively. On the driven wheel mounting base 27, there is a fixedly connected first bearing mounting seat 28, and on the first bearing mounting seat 28, there is a first rolling bearing 29 movably connected to the ball screw B 24. One end of the ball screw B 24 is provided with a handle B 210 or a motor B 213, and the other end is provided with a retaining piece. By rotating the ball screw B 24 forward and backward through the handle B 210 or the motor B 213, the ball screw sleeve B 25 is adjusted to drive the driven wheel device 2 to move forward and backward, thereby driving the distance between the synchronous belt 4 and the edge of the coil or sheet. The automatic operation is realized through the motor B 213, effectively saving labor costs and improving production efficiency.

[0039] As Figure 7 、 Figure 9As shown in the figure, driven guide shafts 26 are provided on both the left and right sides of the ball screw B 24 and penetrate through the driven wheel support 21. A flanged linear bearing B 211 movably connected to the driven guide shaft 26 is provided on one side of the driven wheel support 21. The front and rear ends of the driven guide shaft 26 are fixedly connected to the front and rear driven wheel mounting seats 27. The driven guide shaft 26 effectively controls the stable forward and backward movement of the driven wheel device 2.

[0040] As Figure 7 , Figure 10 shown in the figure, a protective cover B 212 is provided above the driven wheel 23, and a groove through which the synchronous belt 4 passes is provided on the protective cover B 212. The protective cover B 212 ensures the cleanliness of the surface covered for a long time during painting. Using the principles of Faraday electromagnetic induction and physical shielding, the powder hanging design of the transmission device is avoided during long-term shielding, ensuring the stability of the transmission and shielding the driven wheel 23 on the back of the shielding belt.

[0041] The powder spraying shielding device is placed on both sides of the coil or sheet passing through the powder spraying equipment. The powder spraying shielding device can be installed with the driving wheel device 3 and the driven wheel device 2 on the left and right sides of the front side or the rear side, or can be installed on both the front and rear sides. It is specifically determined according to the number of powder spraying equipment to ensure that shielding devices are arranged on both sides of the coil or sheet passing through the powder spraying equipment, effectively solving the technical problems existing in the prior art.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
