Description

Technical Field

[0001] This utility model relates to the field of SCR plate denitrification catalyst production technology, and in particular to a crankshaft press. Background Technology

[0002] SCR plate denitrification catalyst is a catalyst used in selective catalytic reduction (SCR) technology, mainly for the removal of nitrogen oxides (NOx) in industrial flue gas, reducing pollutant emissions;

[0003] The production of SCR catalysts requires the catalyst material to be uniformly and tightly pressed onto the surface of the catalyst plate. Then, high-precision pressure is applied through a press to ensure that each catalyst plate meets the precise requirements for thickness, density and surface smoothness. The press is an indispensable part of the production process of SCR plate denitrification catalysts.

[0004] During the operation of the press, the film helps to enhance the mechanical strength of the catalyst plate and prevent damage or deformation of the plate surface due to excessive pressure. However, although the existing crankshaft press uses a crankshaft structure to provide the required pressure and ensure that the catalyst plate forming process can meet the required technical requirements, the film is generally fixed when the catalyst plate is being pressed. When the film is damaged, it needs to be replaced manually, which is time-consuming and labor-intensive. Secondly, the accuracy of the catalyst plate being transferred to the pressing cutter is not enough. Therefore, this utility model provides a crankshaft press. Utility Model Content

[0033] 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.

[0034] Please see Figure 1-2This utility model provides a technical solution for a crankshaft press: a crankshaft press includes a frame 1, with a transmission mechanism 3 for conveying materials at the upper end of the frame 1. The transmission mechanism 3 includes a transmission frame mounted on the frame 1, and a main rotating shaft 31 and a secondary rotating shaft are respectively provided at both ends of the transmission frame. Both the main rotating shaft 31 and the secondary rotating shaft are fixed to the transmission frame through bearing seats, and multiple transmission wheels 32 are fixed on both the main rotating shaft 31 and the secondary rotating shaft. The multiple transmission wheels 32 on the main rotating shaft 31 and the secondary rotating shaft correspond to each other, and a feeding belt 34 is connected between each pair of corresponding transmission wheels 32. A drive motor 33 is also provided at one end of the main rotating shaft 31. The output end of the drive motor 33 is connected to one end of the main rotating shaft 31. A control box (not shown in the figure) is also provided on the press. By controlling the drive motor 33 to work, it drives the main rotating shaft 31 to rotate, thereby driving multiple transmission wheels 32 to rotate, which in turn drives the feeding belt 34 to rotate, so as to realize the conveying of the material plate. It should be noted that the transmission mechanism 3 is also equipped with a belt tensioning device inside the frame 1. The belt tensioning device adopts the existing conventional and known structure, and its purpose is to adjust the tension of the feeding belt 34. It will not be described in detail here.

[0035] like Figure 3 and 4 As shown, the top of the frame 1 is provided with a crankshaft mechanism 4 for pressing materials. The crankshaft mechanism 4 includes a U-shaped frame provided at the top of the frame 1, and limit vertical plates 41 are symmetrically installed on the inner side of the U-shaped frame. A connecting beam 42 is fixed between the two limit vertical plates 41. Bearing seats 44 are symmetrically installed on the top of the U-shaped frame. A crankshaft 43 is rotatably connected between the two bearing seats 44. The crankshaft 43 is located inside the U-shaped frame and its middle part is rotatably connected to the connecting beam 42. The purpose of the cooperation between the connecting beam 42 and the two bearing seats 44 is to limit and fix the crankshaft 43, so as to facilitate its operation within the U-shaped frame.

[0036] One end of the crankshaft 43 is also fixed with a driven gear 45. A second drive motor 48 is installed on the outer wall of the loop frame. The output end of the second drive motor 48 is connected to a main gear 46. A toothed belt 47 is connected between the driven gear 45 and the main gear 46. When the second drive motor 48 works, it drives the main gear 46 to rotate. The main gear 46 drives the driven gear 45 to rotate through the toothed belt 47, thereby driving the crankshaft 43 to rotate. This makes it convenient for the crankshaft 43 to drive the multiple forming cutters 411 on it to punch and form the material plate.

[0037] The crankshaft mechanism 4 also includes multiple connecting plates 49 connected to the crankshaft 43. The bottom end of each connecting plate 49 is bolted to a forming cutter 411. Slide seats 410 are installed on the upper part of both ends of the connecting plate 49. A slide rail is also provided on the inner wall of the U-shaped frame corresponding to the slide seat 410. The two ends of the connecting plate 49 are slidably connected to the slide rail through the slide seat 410. When the crankshaft 43 rotates, the connecting plate 49 drives the forming cutter 411 to move up and down to press the material plate. When the connecting plate 49 moves up and down, it can slide on the slide rail using the slide seat 410 to improve the stability of the connecting plate 49 when moving, thereby ensuring the stability of the forming cutter 411 during the pressing process.

[0038] like Figure 1 and 5 As shown, a film changing system 2 is provided in the middle of the frame 1 corresponding to the transmission mechanism 3. The film changing system 2 includes a take-up roller 21 and an unwind roller 22 installed vertically on one side of the frame 1, and two guide rollers 23 installed vertically on the other side of the frame 1. The take-up roller 21 and the unwind roller 22 correspond to the two guide rollers 23 respectively. Both ends of the take-up roller 21, the unwind roller 22 and the two guide rollers 23 are fixed to the frame 1 by a bracket 24 and are rotatably connected to the bracket 24. The film roll can be placed on the unwind roller 22, and one end of the film is pulled out and wound around the upper guide roller 23 from above the feeding belt 34, and then wound back to the lower part of the feeding belt 34 from the lower guide roller 23, and finally fixed on the take-up roller 21. In this way, when the material plate is transmitted by the feeding belt 34, the material plate is just between the upper film and the lower film. This facilitates the film to enhance the mechanical strength of the catalyst plate during the operation of the press and avoids damage or deformation of the plate surface due to excessive pressure.

[0039] The film changing system 2 also includes pulleys 25 connected to one end of the take-up roller 21 and the unwind roller 22, and a main motor 26 set on the outer side of one end of the take-up roller 21. The output end of the main motor 26 is fixed to the middle of the pulley 25 at one end of the take-up roller 21. The pulleys 25 at one end of the take-up roller 21 and the unwind roller 22 are connected by a belt. When the film above or below the feeding belt 34 is damaged, the main motor 26 can be started to drive the two pulleys 25 to rotate. At this time, the unwind roller 22 rotates to release the film, while the take-up roller 21 rotates to rewind the film. When the damaged film is rewound, a new film is released for continued use, thus realizing automatic film changing operation.

[0040] like Figure 5 and 6As shown, the frame 1 is also equipped with limiting components for positioning materials on both sides of the transmission mechanism 3. The limiting components include a limiting plate 62 and an adjusting plate 6 installed in the middle of the frame 1 on both sides of the transmission mechanism 3. The adjusting plate 6 and the limiting plate 62 correspond to each other. The limiting plate 62 is fixed to the frame 1 by a fixing rod 63. An adjusting cylinder 61 is installed on one side of the adjusting plate 6 on the frame 1. The telescopic end of the adjusting cylinder 61 is fixed to the middle of the adjusting plate 6. The adjusting plate 6 and the limiting plate 62 are set between the upper film and the lower film of the feeding belt 34 and on both sides of the feeding belt 34. The purpose is to block the material plate on the feeding belt 34 by the blocking mechanism, and then extend the adjusting cylinder 61 to push the adjusting plate 6 closer to the material plate, thereby pushing the material plate closer to the limiting plate 62 to achieve position adjustment. After the adjustment is completed, the forming cutter 411 can perform forming operation on the material plate to ensure the accuracy of forming the material plate.

[0041] like Figure 1 As shown, a material blocking mechanism is also provided on the upper part of the frame 1, directly above the transmission mechanism 3, for blocking the material. The material blocking mechanism includes a material blocking cylinder 5 that is inclinedly installed on the outer wall of the U-shaped frame and located directly above the transmission mechanism 3. The telescopic end of the material blocking cylinder 5 is connected to a baffle 51. Both ends of the baffle 51 are connected to teeth perpendicular to the transmission mechanism 3, and the inner width of the teeth is greater than the width of the feeding belt 34. During the material plate transmission process, the material blocking cylinder 5 extends and pushes the baffle 51 to tilt downward, so that the teeth are engaged with the feeding belt 34, thereby blocking the material plate on the feeding belt 34. This makes it convenient to block the material plate directly below the crankshaft mechanism 4. Then, the limiting component is used to limit the material plate to ensure that the material plate is in place, which is convenient for the forming cutter 411 to perform the forming operation.

[0042] The working principle of this utility model is as follows: During use, the material plate can be placed on the conveying mechanism 3 in sequence by manual or robotic arm, and then conveyed to the bottom of the crankshaft mechanism 4 by the conveying mechanism 3. When it is conveyed to the bottom of the crankshaft mechanism 4, the material plate on the feeding belt 34 is blocked by the material blocking mechanism to facilitate blocking the material plate under the crankshaft mechanism 4.

[0043] Then, the limiting component is used to limit and adjust the material plate to ensure that the material plate is exactly below the forming cutter 411. Then, the crankshaft mechanism 4 is controlled to drive the forming cutter 411 to perform forming operation on the material plate.

[0044] During the molding process, when the film above or below the material plate is damaged, the film changing system 2 can be controlled to perform automatic film changing operations, reducing manual operation and improving work efficiency.

[0045] 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.
