[0002] The distribution cabinet is the final equipment of the distribution system. It is used in situations where the load is relatively dispersed and there are fewer circuits. The motor control center is used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] The raw material of the distribution cabinet shell is generally metal sheet iron. When the distribution cabinet shell is manufactured, a cutting device is generally required to cut the sheet iron into a suitable size. When the existing cutting device cuts the sheet iron, the cutting knife rotates at high speed and cuts the sheet iron, which will generate a lot of noise. At the same time, fine iron filings will fly during cutting, which is not conducive to providing a good processing environment. Working in such a working environment for a long time will bring serious effects on the physical and mental health of the staff. Therefore, the present application proposes a distribution cabinet shell cutting device. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] like Figure 1-Figure 8As shown, a power distribution cabinet housing cutting device proposed in an embodiment of the present application comprises: a cutting table 1, on which a through slot 2 is formed, and a collecting box 3 connected to the through slot 2 is arranged at the bottom of the cutting table 1; the collecting box 3 is used to collect the debris generated by cutting, a bracket 4 is arranged on the cutting table 1, a column 5 is arranged on the bracket 4, and a motor 6 is arranged at the end of the column 5, and a cutting blade 7 corresponding to the through slot 2 is fixedly arranged on the output shaft of the motor 6; a sleeve 8 with an opening at the bottom is slidably sleeved on the column 5, preferably, the number of the columns 5 is two, and the motor 6 The cutting blade 7 is located in the casing 8. The casing 8 is made of a transparent polyester fiber sound-absorbing board. The raw material of the polyester fiber sound-absorbing board is 100% polyester fiber, which has good sound absorption effect and is also convenient for the staff to watch the cutting situation. The opening end of the casing 8 is provided with a frame plate 9. The two opposite sides of the frame plate 9 are rotatably provided with rollers 10, and the other two opposite sides are arrayed with a plurality of sponge strips 11. Preferably, the roller 10 is made of rubber material, and the sponge strip 11 is inclined. Under the action of gravity, the roller 10 overlaps with the table surface of the cutting table 1. , the sponge strip 11 remains in an inclined state. When cutting the raw material iron sheet of the distribution cabinet shell, the iron sheet is placed on the cutting table 1, and then the iron sheet is moved horizontally. The iron sheet first overlaps with the outer arc surface of the roller 10. Under the resistance force generated by the translation of the iron sheet, the roller 10 rolls to the surface of the iron sheet and drives the casing 8 to rise. When the iron sheet moves, the end of the sponge strip 11 overlaps with the iron sheet. Since the overall gravity of the casing 8 and the frame plate 9 is transmitted to the iron sheet through the roller 10, the roller 10 rolls and overlaps with the iron sheet. The resistance force of the sponge strip 11 on the iron sheet is limited, and it only plays a role. The function of reducing the gap is achieved without affecting the normal movement and feeding of the iron sheet. The gap between the frame plate 9 and the iron sheet is reduced by setting the roller 10 and the sponge strip 11. The motor 6 works, and its output shaft drives the cutting blade 7 to rotate, thereby cutting the iron sheet. The noise generated by the rotating cutting of the cutting blade 7 is absorbed and blocked by the casing 8 to reduce the conduction of the noise to the outside world and ensure the physical and mental health of the staff. At the same time, the casing 8 can block the iron filings and dust generated during cutting to avoid the flying of iron filings, thereby ensuring the processing environment of the work station and improving practicality.

[0031] like Figure 1 , Figure 3 and Figure 6As shown, in some embodiments, one side of the casing 8 is connected to a conduit 12, and the end of the conduit 12 is connected to a silencer 13. When the cutting blade 7 cuts the iron sheet, the rotating friction will generate a large amount of heat, and the motor 6 will also generate heat when it operates. The heat is trapped in the casing 8 and cannot be eliminated, which will affect the normal operation of the motor 6. At the same time, part of the iron filings generated by the cutting will not fall into the collection box 3 through the groove 2, but will fall on the iron sheet located in the casing 8. An exhaust fan 14 is arranged on the bracket 4, and the exhaust fan 14 is connected to the casing 8 through an air pipe 15. The outer surface of the air pipe 15 is covered with a sound-absorbing cotton sleeve, and a filter 16 is arranged in the air pipe 15. When the exhaust fan 14 is set, it works. It generates suction to extract the air in the casing 8, and can collect the iron filings and dust in the casing 8, and the air is discharged after filtering, so as to prevent the iron filings from adhering to the surface of the iron sheet and getting stuck between the iron sheet and the roller 10, thereby ensuring that the iron sheet can move normally, and also preventing the iron filings from adhering to the iron sheet and being carried to the outside with the movement of the iron sheet, while the outside air enters the casing 8 through the conduit 12 for gas compensation. Since the conduit 12 is short and close to the cutting blade 7, the silencer 13 is provided to eliminate the noise, so as to prevent the noise from being transmitted to the outside through the conduit 12. The circulation of airflow can cool the casing 8 and ensure the normal operation of the motor 6.

[0032] like Figure 6 As shown, in some embodiments, the silencer 13 includes a sleeve 1301 connected to the conduit 12, and a plurality of conical cylinders 1302 are arranged in an array inside the sleeve 1301. The end of the conical cylinder 1302 with a small opening faces the casing 8. The structure of the plurality of conical cylinders 1302 and the conduit 12 forms a silencer structure, which can reduce the external discharge of noise without affecting the normal circulation of airflow, thereby improving practicality.

[0033] like Figure 5 As shown, in some embodiments, the filter element 16 includes a collecting tube 1601 arranged on the bracket 4 and connected to the air pipe 15, and a filter screen 1602 is arranged in the collecting tube 1601. Preferably, the collecting tube 1601 is arranged vertically, and the air pipe 15 is constructed into two sections, one of which is connected to the side wall of the collecting tube 1601, and the other is connected to the top. Under the action of suction, the air in the shell 8 will carry iron filings into the collecting tube 1601, and the iron filings will be blocked in the lower area by the filter screen 1602, and the air will flow out from the upper area through the filter screen 1602, thereby playing a filtering role.

[0034] like Figure 7As shown, in some embodiments, a T-shaped slot 17 is provided at the bottom of the cutting table 1, and a T-shaped block 18 is constructed on the collecting box 3. The T-shaped block 18 is slidably inserted in the T-shaped slot 17. Through the sliding cooperation between the T-shaped block 18 and the T-shaped slot 17, it is convenient to remove and separate the collecting box 3 from the cutting table 1, and it is convenient to clean the collected debris, thereby improving practicality.

[0035] like Figure 2 and Figure 5 As shown, in some embodiments, the collecting cylinder 1601 is connected with a material guide pipe 19, the free end of the material guide pipe 19 is connected with the collecting box 3 by plugging, and an anti-backflow component 20 is arranged in the material guide pipe 19. Through the arranged material guide pipe 19, the intercepted iron filings can be directly discharged into the collecting box 3, and the arranged anti-backflow component 20 can prevent the iron filings in the collecting box 3 from backflowing due to the action of suction. Preferably, the material guide pipe 19 includes a hard pipe and a soft pipe that are connected, the hard pipe is connected with the collecting cylinder 1601, the anti-backflow component 20 is arranged in the hard pipe, and a through hole is opened on the collecting box 3, and the soft pipe is plugged in with the through hole.

[0036] like Figure 5 As shown, in some embodiments, the backflow prevention member 20 includes a rotating shaft 2001 rotatably disposed in the material guide pipe 19, and an impeller 2002 is fixedly provided on the rotating shaft 2001. Preferably, the longitudinal section of the impeller 2002 is cross-shaped, and the impeller 2002 blocks the material guide pipe 19. When the iron filings intercepted in the collecting cylinder 1601 fall, they will fall on the impeller 2002, thereby driving the impeller 2002 to rotate, so that the iron filings can continue to fall, and the iron filings collected in the collecting box 3 will not produce backflow due to suction.

[0037] like Figure 1 As shown, in some embodiments, a spring 21 mounted on the column 5 is installed between the shell 8 and the bracket 4. By setting the spring 21 and utilizing the elastic force of the spring 21, the roller 10 and the iron sheet are more tightly overlapped, the sponge strip 11 and the iron sheet are more tightly overlapped, and the noise reduction effect is better.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
