[0002] SCR denitrification catalysts are widely used in the field of flue gas denitrification. By using the catalyst, the concentration of nitrogen oxides (NOx) in flue gas is reduced to meet environmental emission standards. The flying shear machine is used to cut metal plates or grid plates for producing SCR (selective catalytic reduction) denitrification catalysts. In the production process of SCR catalysts, it is usually necessary to precisely cut and trim the metal plates to ensure that the catalyst plates that meet the standards are produced.

[0003] In existing flying shear machines, the sheet material is generally directly fed to the flying shear for cutting. However, there is a possibility of misalignment when the sheet material is fed to the flying shear, resulting in uneven cuts and affecting the cutting quality. Therefore, this utility model provides a flying shear machine specifically designed for the production of SCR plate denitrification catalysts. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution for a special flying shear machine for the production of SCR plate denitrification catalysts: A special flying shear machine for the production of SCR plate denitrification catalysts includes a base 1, a drive chamber 3 is provided on one side of the upper end of the base 1, and frames 5 are symmetrically installed on the other side of the upper end of the base 1. A control box 2 is also provided on the top of the base 1 above the frames 5. The top ends of the two frames 5 are connected to a top beam 71, and an upper shear 7 is installed at the bottom end of the top beam 71. Positioning plates 61 are slidably connected to the inner sides of the two frames 5. Eccentric wheels 63 are rotatably connected to the positioning plates 61. The two eccentric wheels 63 are connected to each other through a connecting shaft 64. The frames 5 are portal frames. Slide seats 62 are installed on both sides of the positioning plates 61. The inner wall of the frames 5 is provided with corresponding positions to the slide seats 62. Equipped with a slide rail, the positioning plate 61 is slidably connected to the frame 5 via a slide block 62. One of the eccentric wheels 63 has a driven gear 65 connected to its outer side via a shaft. The drive chamber 3 is equipped with a main motor 66, the output end of which is connected to a main gear. The main gear is connected to the driven gear 65 via a toothed belt. In this design, the main motor 66 controls the rotation of the main gear, which drives the driven gear 65 to rotate, thereby driving the two eccentric wheels 63 to rotate. When both rotate, they will jointly drive the positioning plate 61 to reciprocate up and down inside the frame 5, thereby driving the lower shears 6 to move closer to the upper shears 7 to cut the sheet metal. Each reciprocation is equivalent to one cut. The sheet metal running speed is 0-30 m / min, and the number of cuts is 0-30.

[0024] The tops of the two positioning plates 61 are connected to the lower shears 6. Multiple conveying rollers 8 are arranged side-by-side between the two frames 5, below the upper shears 7. A guide assembly 4 is installed between the two frames 5, in front of the conveying rollers 8. The guide assembly 4 includes a fixed seat 41 installed between the two frames 5. A groove 42 is formed on the upper surface of the fixed seat 41. A bidirectional lead screw 43 is rotatably mounted inside the groove 42. Movable seats 44 are provided at both ends of the bidirectional lead screw 43. The lower ends of the two movable seats 44 are located within the groove 42 and are slidably connected thereto. The bottom ends of the two movable seats 44 are threadedly connected to the two ends of the bidirectional lead screw 43. It should be noted that the threads on the surfaces of the two ends of the bidirectional lead screw 43 run in opposite directions. The bottom ends of the two movable seats 44 have internal threaded holes, and the internal threads are respectively connected to the threads at the two ends of the bidirectional lead screw 43. In order to match the texture, the guide assembly 4 also includes a drive motor 47 mounted on one of the frames 5. The drive motor 47 is fixed to the frame 5 by a bracket. One end of the drive motor 47 passes through the frame 5 and is fixedly connected to one end of the bidirectional lead screw 43. When the drive motor 47 drives the bidirectional lead screw 43 to rotate in the forward direction, the two moving seats 44 will move linearly under the action of the threads at both ends of the bidirectional lead screw 43. That is, the two moving seats 44 will move closer to the middle of the bidirectional lead screw 43 at the same time, so that the two moving seats 44 are closer to each other, thereby reducing the distance between the two moving seats 44. This allows the distance between the two sets of guide wheels 46 to be controlled. Conversely, the drive motor 47 is controlled to reverse, so that the two moving seats 44 are further apart, thereby increasing the distance between the two sets of guide wheels 46, so as to adapt to the guiding operation of plates of different widths.

[0025] Each movable seat 44 is equipped with a fixed frame 45 on its top. Guide wheels 46 are rotatably mounted on the inner side of the fixed frame 45. The guide wheels 46 on the inner sides of the two fixed frames 45 are symmetrically positioned. Figure 5 and 6 As shown, each fixed frame 45 is equipped with a set of guide wheels 46, that is, three guide wheels. The three guide wheels 46 are arc-shaped on the fixed frame 45 to guide and limit the board during board conveying, and better guide the board between the upper shear 7 and the lower shear 6.

[0026] The working principle of this utility model is as follows: When the catalyst plate is sheared, the catalyst plate is transported to the front of the flying shear machine by the conveying equipment. The width of the guide assembly 4 is adjusted appropriately according to the width of the plate so that the spacing between the two sets of guide wheels 46 is suitable for the conveying of the plate of that width.

[0027] After adjustment, the sheet material is first conveyed between two sets of guide wheels 46, then guided by the two sets of guide wheels 46 to the conveying roller 8, and then conveyed by the conveying roller 8 to the area below the upper shear 7. At this time, the control system in the control box 2 is activated to start the flying shear machine, driving the lower shear 6 to move upward in a straight line and tangent to the upper shear 7 to cut the sheet material. Moreover, the lower shear 6 moves in a reciprocating straight line, so that when the sheet material is conveyed without stopping, the lower shear 6 can continuously cut the sheet material at equal distances, making the operation more convenient.

[0028] In addition, the control box 2 in this design is integrated with the equipment, so there is no separate configuration of the control box 2, making the structure more compact.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
