DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 As shown, the utility model provides a cutting device for processing a low-voltage switch cabinet, including a cutting device assembly 1, a safety door 2 is movably connected to the front of the cutting device assembly 1, and through-holes 3 are respectively opened at the front and back of the cutting device assembly 1, and a controller 4 is fixedly connected to the upper left side of the front of the cutting device assembly 1, and a feed port 6 is opened in the middle of the left side of the cutting device assembly 1, and an operating table 5 is fixedly connected below the feed port 6;

[0028] The setting of the safety door 2 facilitates the taking out of the cut plate, the setting of the through opening 3 facilitates the discharge of residues during cutting through the movement of the internal structure of the cutting device assembly 1, and the setting of the operating table 5 facilitates the placement of the original plate material.

[0029] like Figure 2As shown, the cutting device assembly 1 includes a box body 11, a conveyor frame 12 is fixedly connected to the lower left side of the inner wall of the box body 11, a plurality of rotating shafts 13 are movably connected to the inner rectangular array of the conveyor frame 12, a plurality of rotating shafts 13 are movably connected to the outer surfaces of the plurality of rotating shafts 13 with a conveyor belt 14, a limiting assembly 15 is arranged above the conveyor belt 14, a strip plate 19 is overlapped on the lower surface of the inner wall of the box body 11, a lifting assembly 16 is arranged in the middle of the upper surface of the strip plate 19, a motor 17 is arranged on the front of the lifting assembly 16, and the motor 17 is arranged on the front of the motor 17. The output shaft of 7 is fixedly connected with a cutting wheel 18, the lower surface of the inner wall of the box body 11 is overlapped with a rack 110 on both sides, the bottom of the rack 110 is movably connected with a plurality of rollers, the outer surfaces of the plurality of rollers overlap the bottom of the box body 11, the upper surface of the rack 110 is meshed with a gear 111, the left and right sides of the box body 11 are respectively fixedly connected with a motor 2 112, the output shaft of the motor 2 112 is fixedly connected with the back of the gear 111, and the rear end of the rack 110 is fixedly connected with the front of the strip plate 19;

[0030] When it is needed, the plate is placed on the operating table 5 and the plate is transported and moved through the action of the conveying frame 12, the rotating shaft 13, and the conveyor belt 14. While moving, the position of the plate is limited by the setting of the limit assembly 15. When the plate moves to the appropriate position, the rotating shaft 13 and the conveyor belt 14 stop moving, and the cutting wheel 18 rotates at a high speed through the action of the motor 17. Then, the motor 17 and the cutting wheel 18 are moved downward through the setting of the lifting assembly 16, so that the cutting wheel 18 contacts the plate and cuts it. At the same time, the motor 2 112, the gear 111 and the rack 110 cooperate with each other, thereby driving the rack 110 to move and drive the strip plate 19 and the lifting assembly 16 to move, so as to cut and drop the plate. At the same time, when the strip plate 19 moves, the residue cut out by the cutting wheel 18 is cleaned and discharged through the through port 3. The roller at the bottom of the rack 110 is set to reduce the effect of friction during movement.

[0031] like Figure 3 and Figure 4 As shown, the lifting assembly 16 includes a support plate 161, a slide groove 162 is provided on the front of the support plate 161, a motor three 165 is fixedly connected to the top of the support plate 161, a threaded rod 163 is fixedly connected to the output shaft of the motor three 165, a slider 164 is threadedly connected to the outer surface of the threaded rod 163, the outer surface of the slider 164 is slidably connected to the inside of the slide groove 162, the front of the slider 164 is fixedly connected to the back of the motor one 17, a protective steel plate 166 is fixedly connected to the top of the motor three 165, a square top block is fixedly connected to the right side of the motor three, the upper end of the square top block is fixedly connected to the lower surface of the protective steel plate 166, and the lower end of the square top block is fixedly connected to the upper surface of the support plate 161;

[0032] The motor three 165 is configured to drive the threaded rod 163 to rotate and cause the slider 164 to slide upward in the slide groove 162. When the slider 164 moves upward, it drives the motor 17 and the cutting wheel 18 to move upward, thereby realizing the lifting operation to cut the plate. The protective steel plate 166 is configured to protect the motor 17 to prevent the cut plate from falling and causing damage to it.

[0033] like Figure 5 As shown, the limiting assembly 15 includes a spring plate 151, and a fixing frame 152 is fixed to the right side of the front and rear sides of the spring plate 151 respectively, and a pressure wheel 153 is movably connected below the opposite surface of the fixing frame 152, and the outer surface of the pressure wheel 153 overlaps the upper surface of the conveyor belt 14, and four springs 154 are fixedly connected to the upper surface of the inner wall of the box body 11 in a rectangular array. The upper end of the spring 154 is fixedly connected to the upper surface of the inner wall of the box body 11, and a telescopic shaft 155 is fixedly connected to the upper surface of the spring plate 151. The upper end of the telescopic shaft 155 is fixedly connected to the upper surface of the inner wall of the box body 11, and the left end of the spring plate 151 overlaps the left side of the inner wall of the box body 11. The outer surface of the pressure wheel 153 is fixedly connected to the limiting ring 1531 on the front and rear sides respectively, and the surface of the pressure wheel 153 is sleeved with a rubber sleeve 1532, and the front and rear ends of the rubber sleeve 1532 overlap the opposite surface of the limiting ring 1531, and the outer surface of the rubber sleeve 1532 is provided with a rough surface 1533;

[0034] When the plate conveying device is affected by the thickness of the plate, the pressure wheel 153 rolls after contacting with the pressure wheel 153. At the same time, due to the setting of the fixed frame 152 and the spring plate 151, the spring 154 and the telescopic shaft 155 are squeezed and contracted. Since the spring 154 has strong elasticity after being squeezed and contracted, the elastic action of the contracted spring 154 makes the pressure wheel 153 and the plate fit tightly and tighten to achieve a limiting phenomenon. The setting of the telescopic shaft 155 limits the position of the spring plate 151 to prevent the occurrence of position shaking.

[0035] like Figure 6 As shown, the front and rear sides of the outer surface of the pressure wheel 153 are respectively fixedly connected to the limit ring 1531, and the surface of the pressure wheel 153 is sleeved with a rubber sleeve 1532. The front and rear ends of the rubber sleeve 1532 are respectively overlapped with the opposite surface of the limit ring 1531, and the outer surface of the rubber sleeve 1532 is provided with a rough surface 1533;

[0036] The setting of the limiting ring 1531 can limit the position of the plate to prevent it from shaking back and forth when cutting the plate, and the width of the plate is just stuck between the limiting rings 1531 on both sides. The setting of the rubber sleeve 1532 can protect the surface of the plate to prevent the pressure wheel 153 from directly contacting the plate and causing scratches. The setting of the rough surface 1533 can increase the friction force.

[0037] The following is a detailed description of the working principle of the plate cutting device for low-voltage switchgear processing.

[0038] When it is needed, the plate is placed on the operating table 5 and the plate is transported and moved through the action of the conveying frame 12, the rotating shaft 13, and the conveyor belt 14. While moving, the position of the plate is limited by the setting of the limit assembly 15. Under the elastic action of the spring 154, the pressure wheel 153 is tightly fitted and tightened with the plate, and the limiting ring 1531, the rubber sleeve 1532, and the rough surface 1533 cooperate to achieve the limiting phenomenon. When the plate moves to the appropriate position, the rotating shaft 13 and the conveyor belt 14 stop moving, and the motor 17 and the cutting wheel 18 rotate together, and then the lifting assembly 16 is set to contact and cut the plate. The motor 2 112, the gear 111 and the rack 110 cooperate with each other to drive the rack 110 to move and drive the strip plate 19 and the lifting assembly 16 to move, so that the plate is cut and dropped. The residue is cleaned during movement and discharged through the opening 3.

[0039] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
