Description

Technical Field

[0001] This utility model belongs to the field of screening technology, specifically relating to an automatic weighing and screening device for pipes. Background Technology

[0002] Pipes, as essential industrial materials (such as metal pipes, plastic pipes, and composite pipes), are widely used in numerous fields including petroleum, natural gas, chemical, construction, machinery manufacturing, and water and heating supply. The weight of pipes is one of their key quality indicators, directly affecting their physical properties, safety in use, and cost control. Excessive weight deviation may indicate problems such as uneven wall thickness, material defects, abnormal density, or length errors. Therefore, accurate weight inspection and screening of pipes during the production process is crucial for ensuring product quality, reducing scrap rates, and lowering production costs. In actual pipe production, manual sampling and weighing are typically relied upon. This method is not only labor-intensive and costly, but also difficult to adapt to fast-paced production, often impacting production efficiency and cost control. Utility Model Content

[0003] Therefore, this utility model aims to solve the problem of relying on manual sampling and weighing in the existing technology. This method is not only labor-intensive and costly, but also difficult to adapt to the fast pace of production, which often affects the production efficiency and cost control of products.

[0004] Therefore, the technical solution adopted is an automatic weighing and screening device for pipes according to this utility model, including a support, an inclined platform at the top of the support, a baffle hinged to the lower end of the inclined platform, a tilting cylinder hinged to the support below the inclined platform, the piston rod of the tilting cylinder hinged to the bottom end of the baffle, a bearing plate inside the support, an electronic scale on the bearing plate, and multiple pushing cylinders on both sides of the electronic scale, the piston rod of the pushing cylinder being connected upward to a pushing block, the pushing block being a right-angled triangle shape.

[0005] Preferably, the piston rod of the pusher cylinder is connected to the pusher block by bolts.

[0006] Preferably, a buffer cylinder is provided on the support plate, and the piston rod of the buffer cylinder is connected upward to the bottom end of the V-shaped block.

[0007] Preferably, multiple protrusions are provided at intervals on both the inclined platform and the baffle.

[0008] Preferably, a guide plate is provided on the side of the support away from the baffle.

[0009] Preferably, the lower end of the bracket is provided with multiple bases.

[0010] This utility model has the following advantages: By comparing with set parameters, the pipes are divided into qualified products and products awaiting inspection. Qualified products are pushed upwards into the finished product cage by the pusher on the right, while products awaiting inspection are pushed upwards by the pusher on the left and slid into the inspection area via the guide plate for centralized processing. This transforms manual sampling into equipment operation, saving manpower, improving production efficiency, and enhancing the quality of pipe screening.

[0019] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly or indirectly attached to that other component. When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to that other component.

[0021] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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 element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] This utility model provides an automatic weighing and screening device for pipes, such as... Figure 1-4 As shown, the system includes a support frame 1, with a ramp 2 at the top and a baffle 3 hinged to the lower end of the ramp 2. A tilting cylinder 4 is hinged to the support frame 1 below the ramp 2, and the piston rod of the tilting cylinder 4 is hinged to the bottom end of the baffle 3. A support plate 5 is installed inside the support frame 1, and an electronic scale 6 is installed on the support plate 5. Multiple pushing cylinders 7 are installed on both sides of the electronic scale 6, and the piston rods of the pushing cylinders 7 are connected upward to a pushing block 8, which is a right-angled triangle. An electrical cabinet and an industrial computer are installed on the support frame 1. A PLC controller is installed in the electrical cabinet, and the industrial computer contains an MES production management system. The PLC controller receives the weighing data and transmits it to the industrial computer via 485 communication. The data acquisition program then uploads the real-time production data to the MES production management system.

[0024] The piston rod of the pusher cylinder 7 is bolted to the pusher block 8, facilitating the installation and removal of the pusher block 8. A buffer cylinder 9 is installed on the bearing plate 5, with its piston rod connected upwards to the bottom of the V-shaped block 10. This buffer cylinder receives the pipes as they are turned over, providing cushioning and preventing damage. Multiple protrusions 11 are spaced apart on the inclined platform 2 and the baffle 3 to increase friction and prevent slippage of the pipes. A guide plate 12 is installed on the side of the support 1 away from the baffle 3, facilitating the movement of the pipes to the inspection area. Multiple bases 13 are installed at the lower end of the support 1 for stable support.

[0025] The working principle and beneficial effects of the above technical solution are as follows: A traction machine pushes the pipe between the inclined platform 2 and the baffle 3. The tilting cylinder 4 is activated, causing the baffle 3 to rotate downwards, and the pipe falls into the V-shaped block 10. The buffer cylinder 9 is then activated, placing the pipe onto the electronic scale 6 for weighing. The weight is compared with set parameters, and after comparison, the pipe is divided into qualified products and products awaiting inspection. Qualified products are pushed upwards into the finished product cage by the pusher block 8 on the right, while products awaiting inspection are pushed upwards by the pusher block 8 on the left and slide into the inspection area via the guide plate 12 for centralized processing. This transforms the original manual sampling inspection into equipment operation, saving manpower, improving production efficiency, and simultaneously improving the quality of pipe screening.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
