Abstract

The utility model discloses an automatic loading device for vanadium-nitrogen alloy finished products, which belongs to the technical field of vanadium-nitrogen alloy finished product production, and includes a base, and a conveyor is arranged on the top surface of the base. In the utility model, the bottom surface of the discharge pipe and the top surface of the vanadium-nitrogen alloy finished product in the loading box are fixed and small by using the coordinated use of a controller, an electric hydraulic rod, a lifting plate and a distance sensor. When the weighing sensor detects that the weight of the vanadium-nitrogen alloy finished product in the loading box reaches the required weight, the electric push rod is used to drive the push column to push the sealing plate closed. At this time, because the distance between the bottom end of the discharge pipe and the loading box is small, it is effectively avoided that after the weighing sensor detects that the weight reaches the standard, a part of the material under the discharge pipe is in a falling state, and this part of the material will cause the problem of over-quantity after falling into the loading box, so as to ensure that the error of material loading is controlled within a certain small range.

Description

Technical Field

[0001] The utility model relates to the technical field of production of vanadium-nitrogen alloy finished products, and more specifically to an automatic loading device for vanadium-nitrogen alloy finished products. Background Art

[0002] Vanadium-nitrogen alloy is an important alloy material, the main components of which are vanadium and nitrogen. Vanadium-nitrogen alloy has the advantages of high hardness, high strength, wear resistance, and corrosion resistance, and is widely used in many fields. At present, vanadium-nitrogen alloy is mainly used in the steel metallurgical industry to produce high-strength, high-hardness, and wear-resistant steel. After the vanadium-nitrogen alloy product is produced, it needs to be loaded.

[0003] After searching, the utility model patent with announcement number CN217295102U discloses an automatic loading device for vanadium-nitrogen alloy finished products, including a horizontal conveyor, a box placing machine and a material placing machine are arranged on the left side of the top of the horizontal conveyor, a weighing sensor located below the discharge port of the material placing machine is fixedly connected to the top of the horizontal conveyor, a loading box is placed on the top of the weighing sensor, a box loading mechanism is arranged on the back of the box placing machine, a material placing mechanism is arranged on the front end of the horizontal conveyor, the box placing machine includes a first box body, and a material placing port is arranged on the right side of the bottom of the first box body; the patent senses the weight of the vanadium-nitrogen alloy in the loading box by arranging a weighing sensor on the top of the horizontal conveyor, and can quickly cut off the material placing of the material placing machine when the weight reaches the standard, thereby avoiding too much or too little vanadium-nitrogen alloy in the box, thereby achieving accurate loading and improving the loading efficiency. Since the box placing, material placing and conveying are all completed by machines, human resources can be saved and production capacity can be improved.

[0004] However, the above patent still has the following shortcomings: the weight of the vanadium-nitrogen alloy in the charging box is weighed by a weighing sensor, and the discharge of the discharger is quickly cut off when the weight reaches the standard. However, when the weighing sensor detects that the weight reaches the standard, a part of the material is already in a falling state at the discharge port of the discharger. This part of the material will cause excess after falling into the box, which will cause a large weight error of the charging; and because the vanadium-nitrogen alloy finished product has a certain shape, there is a risk of blocking when it is discharged from the discharger. For this reason, we propose an automatic loading device for vanadium-nitrogen alloy finished products. Utility Model Content

[0028] For details, please refer to Figures 1 to 3The pushing mechanism 7 includes a plurality of support seats 14 fixedly connected to the top surface of the lifting plate 6 and a servo motor 16 fixedly installed on the top surface of the lifting plate 6. The inner side surfaces of the support seats 14 are fixedly connected with springs 15, and the ends of the springs 15 are in contact with the side surfaces of the discharge barrel 8. The side surfaces of the discharge barrel 8 are fixedly connected with support slide bars 18, and the ends of the support slide bars 18 are movably sleeved with the support seats 14. The output shaft of the servo motor 16 is fixedly sleeved with a cam 17, and the side surfaces of the cam 17 are in contact with the side surfaces of the discharge barrel 8.

[0029] In this embodiment, the discharge barrel 8 is supported by the cooperation of the support seat 14 and the support slide bar 18, and the discharge barrel 8 is driven to reset by the elastic force of the spring 15.

[0030] For details, please refer to Figure 1 and Figure 2 A weighing sensor 20 is provided on the conveyor 2 , a charging box 21 is placed on the top surface of the weighing sensor 20 , and the bottom end of the discharge pipe 9 extends to the inner cavity of the charging box 21 .

[0031] In this embodiment, a loading box 21 is used to catch the vanadium-nitrogen alloy products dropped from the discharge pipe 9, and a weighing sensor 20 is used to weigh the dropped vanadium-nitrogen alloy products. The loading box 21 can be placed on the weighing sensor 20 by an existing box placing machine.

[0036] For details, please refer to Figure 1 A controller 22 is fixedly installed on the outer side of the conveyor 2.

[0037] In this embodiment, the device is controlled by a controller 22 .

[0038] Working principle: When in use, first put the vanadium-nitrogen alloy finished product into the inner cavity of the discharge barrel 8. When the loading box 21 is moved to the bottom of the discharge pipe 9 by the conveyor 2, the electric hydraulic rod 5 is started to drive the lifting plate 6 and the discharge barrel 8 to move downward, and the distance sensor 13 is used to detect the distance between the bottom surface of the discharge pipe 9 and the bottom surface of the inner cavity of the charging box 21. Then the electric push rod 11 is started to drive the push column 12 to move outward. At this time, the sealing plate 10 flips downward, so that the vanadium-nitrogen alloy finished product in the discharge barrel 8 falls from the discharge pipe 9 into the charging box 21. As the vanadium-nitrogen alloy finished product material in the charging box 21 increases, the distance sensor 13 detects that the distance between the discharge pipe 9 and the material is shortened. At this time, the controller 22 controls the electric hydraulic rod 5 to drive the lifting plate 6 and the discharge barrel 8 to move upward, so that the bottom surface of the discharge pipe 9 and the material are always at the rated distance. Then, when the material in the discharge barrel 8 falls, the servo is started. The motor 16 drives the cam 17 to rotate, and the rotation of the cam 17 is used to push the discharge barrel 8, and the elastic force of the spring 15 is used to drive the discharge barrel 8 to reset, so that the discharge barrel 8 and the discharge pipe 9 move forward and backward, so that the material in the discharge barrel 8 has a sense of vibration, thereby assisting the material to fall, and at the same time, the fallen vanadium-nitrogen alloy products are evenly loaded into the charging box 21. Finally, when the weighing sensor 20 detects that the weight of the vanadium-nitrogen alloy products in the charging box 21 reaches the required weight, the electric push rod 11 is started to drive the push column 12 to push the sealing plate 10, and the sealing plate 10 is used to prevent the material in the discharge pipe 9 from falling. In addition, the distance between the bottom end of the discharge pipe 9 and the charging box 21 is small, which effectively avoids the situation where a part of the material under the discharge pipe 9 is in a falling state after the weighing sensor 20 detects that the weight meets the standard, and this part of the material falls into the charging box 21, which will cause the problem of overweight.
