Description

Technical Field

[0001] This utility model belongs to the field of hot-dip galvanizing, specifically a weighing and unloading device for hot-dip galvanizing standard parts. Background Technology

[0002] Galvanizing is an effective method of metal corrosion protection, mainly used in metal structures across various industries. It plays an irreplaceable role in reducing corrosion, extending the service life of steel components, and saving energy and materials. Before hot-dip galvanizing standard parts, multiple standard parts of a certain weight need to be placed in a material bucket, and then the bucket and standard parts are placed together into the hot-dip galvanizing equipment.

[0003] Figure 1 This is a schematic diagram of a standard parts hot-dip galvanizing weighing and unloading device in the prior art, including a mesh belt 1, a slide 2 fixed at the end of the mesh belt 1, a weighing pan 3 below the slide 2, and a material bucket 12 placed on the weighing pan 3. Several standard parts are conveyed by the mesh belt 1, slide through the slide 2 into the material bucket 12, and the weighing pan 3 weighs the standard parts. When the material reaches the specified weight, the mesh belt 1 stops conveying, and the robotic gripper 11 grabs the material bucket 12 and places it into the subsequent hot-dip galvanizing equipment.

[0004] The above-mentioned weighing and unloading device has the following shortcomings: the unloading method of feeding the material to the material bucket 12 through the slide 2 will cause the standard parts to be concentrated in a certain part of the material bucket 12. After the robot gripper 11 grabs the material, it is difficult to spread the material in the material bucket 12 evenly. As a result, during hot-dip galvanizing, the standard parts will stick together or be galvanized unevenly due to accumulation, which will affect the galvanizing effect. Utility Model Content

[0005] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a standard hot-dip galvanized parts weighing and unloading device, so as to achieve the purpose of placing materials more evenly in the material bucket.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A standard hot-dip galvanizing weighing and unloading device includes a mesh belt, a weighing pan located below the end of the mesh belt, and a receiving bucket placed on the weighing pan. A material equalization frame is provided on the weighing pan, and a material dropping bucket is fixed on the material equalization frame. The upper and lower ends of the material dropping bucket have opening structures. The opening structure at the upper end of the material dropping bucket faces the end of the mesh belt. The receiving bucket is placed below the opening structure at the lower end of the material dropping bucket. A stroke mechanism that reciprocates along the height direction is also fixed on the material equalization frame. The actuating end of the stroke mechanism is fixedly connected to a cover plate for closing the opening structure at the lower end of the material dropping bucket. The cover plate is a cone-shaped structure with the tip pointing upwards and the tip of the cone facing the end of the mesh belt. When the stroke mechanism moves upwards, a gap is formed between the cover plate and the lower opening of the material dropping bucket, allowing material to pass through. When the stroke mechanism moves downwards, the cover plate closes the lower opening of the material dropping bucket.

[0007] As a limitation of this utility model: the cover plate has a conical structure, the lower opening of the material discharge bucket is circular, the inner diameter of the lower opening of the material discharge bucket is less than or equal to the outer diameter of the cover plate, and the actuating end of the stroke mechanism is fixedly connected to the tip of the cover plate.

[0008] As a limitation of this utility model: the upper opening of the material discharge bucket is circular, and the size of the upper opening is larger than the size of the lower opening.

[0009] As a limitation of this utility model: a top plate is fixed on the top surface of the material distribution frame, and a through hole adapted to the upper opening of the material drop hopper is opened on the top plate, and the upper end of the material drop hopper is fixed in the through hole opened on the top plate.

[0010] As a limitation of this utility model: a travel mechanism support is fixedly provided on the top plate, and the travel mechanism is fixedly mounted on the travel mechanism support.

[0011] As a limitation of this utility model: the stroke mechanism includes a cylinder fixed on the stroke mechanism support, the movable end of the cylinder extending downward and fixedly connected to the tip of the cover plate.

[0012] As a limitation of this utility model: the material distribution frame is fixed on the weighing pan.

[0013] As a limitation of this utility model: the end of the mesh belt is fixed with an inclined downward slide, and the end of the slide is set toward the tip of the cover plate.

[0014] As a limitation of this utility model: the slide is an inverted trapezoidal plate that is larger at the top and smaller at the bottom, and baffles perpendicular to the slide are fixed on both sides of the slide.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0016] (1) The present invention has a material distribution frame fixed on the weighing pan. The material distribution frame is equipped with a material drop bucket with a larger upper part and a smaller lower part and a conical cover plate with a smaller upper part and a larger lower part. Through the conical structure of the cover plate, the material is naturally dispersed in different directions in the material drop bucket after falling from the tip of the conical cover plate. When the weight of the material on the weighing pan reaches the set value, the control system controls the stroke mechanism to open the cover plate. Since the material is naturally dispersed in the material drop bucket, the material will also be dispersed from the material drop bucket into the receiving bucket after the cover plate is opened, so that the material is placed more evenly in the receiving bucket, avoiding the adhesion or uneven galvanizing of standard parts due to accumulation.

[0017] (2) The material discharge hopper of this utility model has an open structure with a large upper part and a small lower part, which provides a large opening area for feeding. At the same time, a slide and a baffle are set at the end of the mesh belt to ensure that all materials fall into the material discharge hopper as much as possible, thus avoiding the material from scattering outside the receiving hopper to the greatest extent.

[0018] In summary, this utility model enables materials to fall evenly and dispersedly into the receiving bucket, avoiding adhesion or uneven galvanizing of standard parts due to accumulation, resulting in better galvanizing effect. It is suitable for weighing and cutting small materials before hot-dip galvanizing, and is especially suitable for weighing and cutting standard parts before hot-dip galvanizing.

[0026] The preferred embodiments of this utility model are described below with reference to the accompanying drawings. It should be understood that the standard hot-dip galvanizing weighing and unloading device described herein is a preferred embodiment and is only used for illustration and explanation of this utility model, and does not constitute a limitation thereof.

[0027] The directional terms or positional relationships used in this utility model, such as "up," "down," "left," and "right," are based on the positional relationships in the accompanying drawings of this utility model. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0028] This implementation example Figures 2-5As shown, a standard hot-dip galvanizing weighing and unloading device includes a mesh belt 1, a weighing pan 3 located below the end of the mesh belt 1, and a receiving bucket 4 placed on the weighing pan 3. A material distribution frame 5 is provided on the weighing pan 3, and a dropping bucket 7 is fixed on the material distribution frame 5. The dropping bucket 7 has an opening structure at both the upper and lower ends. A stroke mechanism that reciprocates along the height direction is also fixed on the material distribution frame 5. A cover plate 10 for closing the lower opening structure of the dropping bucket 7 is fixed to the actuating end of the stroke mechanism. When the stroke mechanism moves upward, a gap is formed between the cover plate 10 and the lower opening of the dropping bucket 7 that allows material to pass through. When the stroke mechanism moves downward, the cover plate 10 closes the lower opening of the dropping bucket 7.

[0029] Specifically, such as Figure 2 As shown, the mesh belt 1 is a conveyor belt in the prior art. The mesh belt 1 is connected to the control system (not shown in the figure) by signal. The material is conveyed to the tray by the mesh belt 1. In order to further gather the falling material, an inclined downward slide 2 is fixed at the end of the conveying direction of the mesh belt 1. The slide 2 is an inverted trapezoidal plate with a larger top and a smaller bottom. Baffles perpendicular to the slide 2 are fixed on both sides of the slide 2. The material is gathered under the action of the slide 2 and the baffles, thereby preventing small materials from scattering outside the receiving bucket 4.

[0030] like Figures 2-4 As shown, the weighing pan 3 is a weighing pan in the prior art. The weighing pan 3 is connected to the control system signal. The main structure is rectangular. A material distribution frame 5 is fixed on the weighing pan 3. The material distribution frame 5 is a cubic frame structure made of welded square tubes. In this embodiment, the material distribution frame 5 is fixedly connected to the weighing pan 3 to ensure the structural stability of the entire device during the feeding process. In other embodiments, the material distribution frame 5 can also be placed directly on the weighing pan 3.

[0031] A material distribution frame 5 is fixedly mounted with a material discharge bin 7. The material discharge bin 7 is a hollow, inverted frustum-shaped structure, wider at the top and narrower at the bottom. Both the top and bottom ends of the material discharge bin 7 have circular openings, with the upper opening being larger than the lower opening. A top plate 6 is fixedly mounted on the top surface of the material distribution frame 5. The top plate 6 has a circular through hole that matches the upper opening of the material discharge bin 7. The upper end of the material discharge bin 7 is fixed in the through hole on the top plate 6, and the opening at the top of the material discharge bin 7 faces the end of the chute 2. The structure of the material discharge bin 7, wider at the top and narrower at the bottom, further ensures that all materials can fall into the material discharge bin 7. A receiving bin 4 is placed below the lower opening of the material discharge bin 7, allowing the materials in the material discharge bin 7 to fall into the receiving bin 4. The structure of the receiving bin 4 is existing technology.

[0032] A stroke mechanism support 8 is fixedly installed on the top plate 6 of the material distribution frame 5. The stroke mechanism support 8 has a "U" shaped structure, including uprights located on both sides of the material drop hopper 7 and a horizontal bar fixedly placed above the uprights. A stroke mechanism capable of reciprocating along the height direction is fixed on the horizontal bar. In this embodiment, the stroke mechanism is a cylinder 9. The cylinder body of the cylinder 9 is fixed on the horizontal bar along the height direction. The piston of the cylinder 9 passes through the horizontal bar and extends downward. A cover plate 10 extending into the material drop hopper 7 and used to close the opening structure at the lower end of the material drop hopper 7 is fixed at the lower end of the piston of the cylinder 9. The cover plate 10 is a conical structure with the tip pointing upwards. The outer diameter of the cover plate 10 is equal to or larger than the inner diameter of the lower opening of the material drop hopper 7, so as to ensure that the cover plate 10 can completely cover the lower opening of the material drop hopper 7. The tip of the cover plate 10 is set towards the end of the chute 2. In this way, when the material falls from the end of the chute 2, it will fall to the tip of the cover plate 10 and slide naturally in different directions of the tip of the cover plate 10 under the action of the conical structure of the cover plate 10, thereby achieving the effect of uniformly dispersing the material.

[0033] The travel mechanism is connected to the control system via signals. For example... Figure 5 As shown, during material discharge, the piston of cylinder 9 extends downwards, and cover plate 10 closes the lower opening of the discharge bin 7. The robot gripper 11 grasps the receiving bin 4, keeping it suspended in the air. The opening of the receiving bin 4 is aligned with the lower opening of the discharge bin 7. The material passes through the mesh belt 1 and the chute 2 along the direction of the arrow in the figure, continuously conveying it to the tip of cover plate 10. Under the action of cover plate 10, it freely disperses and slides into the closed structure formed by cover plate 10 and discharge bin 7. Since the material equalization frame 5 is set on the weighing... As material falls between the cover plate 10 and the material dropper 7 on the weighing pan 3, the reading on the weighing pan 3 continuously increases. When the reading on the weighing pan 3 reaches the set value, the control system stops the conveyor belt 1 and controls the piston of the cylinder 9 to retract upwards, causing the cover plate 10 to move upwards, creating a gap between the cover plate 10 and the lower opening of the material dropper 7 that allows material to pass through. The material falls through this gap into the receiving bin 4, and finally, the robot gripper 11 places the receiving bin 4 into the hot-dip galvanizing equipment. Alternatively, the receiving bin 4 can be placed directly on the weighing pan 3, and the corresponding material drop setting value can be set based on experience. After the material falls into the receiving bin 4, the control system controls the robot gripper 11 to remove the receiving bin 4.

[0034] In other embodiments, the travel mechanism can also be an electric push rod, or a motor and lead screw mechanism, etc., as long as it can drive the cover plate 10 to reciprocate in the height direction. The material in this embodiment can be a flat washer among standard parts. In addition to flat washer, this embodiment can also be used for weighing and cutting standard parts such as bolts and nuts before hot-dip galvanizing. Of course, this embodiment can also be applied to weighing and cutting small parts other than standard parts before hot-dip galvanizing.
