Technical Field
[0001] This utility model relates to the field of weighing machine technology, specifically a fully automatic steel coil weighing machine based on PLC control. Background Technology
[0002] In the steel production and processing industry, steel coils are important raw materials or semi-finished products, and the accurate measurement of their weight is crucial for production cost control, product quality assurance, and logistics transportation.
[0003] Traditional steel coil weighing methods rely heavily on manual operation, resulting in low efficiency, large errors, and high labor intensity. With the development of automation technology, fully automated weighing equipment has gradually become a necessity in the industry, aiming to improve weighing efficiency, reduce human error, and lower the labor intensity of operators.
[0004] In particular, weighing systems based on PLC (Programmable Logic Controller) control are widely used in industrial automation due to their high precision, high reliability, and ease of programming. However, existing fully automatic steel coil weighing machines still have shortcomings in terms of flexibility, adaptability, and stability. For example, they are difficult to adapt to the weighing requirements of steel coils of different sizes, are inconvenient to move, and are susceptible to vibration and impact during the weighing process, which can lead to weighing errors.
[0005] To address this issue, we propose a PLC-controlled fully automatic steel coil weighing machine. Summary of the Invention
[0006] The purpose of this invention is to provide a fully automatic steel coil weighing machine based on PLC control, which solves the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic steel coil weighing machine based on PLC control, including a base plate, a weighing platform arranged on the top of the base plate, a buffer pad fixedly installed on the bottom surface of the weighing platform, the bottom surface of the buffer pad being fixedly installed with the top surface of the base plate, the weighing platform being signal-connected to a display via a connecting cable, and the display being connected to the top surface of the base plate via an adjustment component.
[0008] Preferably, casters are fixedly installed at the bottom of the four corners of the base plate. By installing casters at the four corners of the base plate, the mobility and flexibility of the weighing machine are significantly enhanced. Whether in the workshop or in cross-regional transportation, the weighing machine can be easily moved and positioned quickly, improving work efficiency and convenience.
[0009] Preferably, the base plate is threaded with bolts, the bottom end of the bolts is fixedly mounted with a chassis, and the top end of the bolts is fixedly mounted with a knob. The design of the threaded bolts and chassis, combined with the knob operation, allows the weighing machine to be quickly adjusted and fixed in position when stable weighing is required.
[0010] Preferably, the outer wall of the buffer pad has a corrugated design, and there are two buffer pads arranged symmetrically. The corrugated design of the buffer pad not only increases the contact area between the buffer pad and the weighing platform and the base plate, but also effectively absorbs the impact force generated when the steel coil is placed through its elastic properties. The two symmetrically arranged buffer pads further ensure the stability and balance during the weighing process, reduce the weighing error caused by vibration and impact, and improve the accuracy of weighing.
[0011] Preferably, an installation rod is fixedly installed on the top surface of the weighing platform, and an arc-shaped elastic clamping piece is fixedly installed on the top surface of the installation rod. The arc-shaped elastic clamping piece, which is fixed to the weighing platform by the installation rod, provides a stable clamping force for the steel coil. Its arc-shaped design can better fit the shape of the steel coil, ensuring that the steel coil will not slip or shift during the weighing process, thereby ensuring the stability and accuracy of the weighing.
[0012] Preferably, the adjusting component includes an adjusting column, with a hollow column slidably fitted onto the outside of the adjusting column. The bottom end of the hollow column is fixedly installed to the top surface of the base plate. An mounting block is fixedly installed on the outer wall of the adjusting column. A locking rod is movably connected to the mounting block via a pin. The lower end of the locking rod engages with a slot on the top surface of the auxiliary plate. The bottom surface of the auxiliary plate is fixedly installed to the top surface of the base plate. The design of the adjusting component allows the height of the clamping device to be flexibly adjusted according to steel coils of different sizes. Fixing is achieved by sliding the adjusting column within the hollow column and utilizing the engaging action of the locking rod and the slot. This process is simple and quick, with a wide adjustment range, meeting the weighing requirements of various specifications of steel coils and improving the versatility and flexibility of the weighing machine.
[0013] Preferably, the inner wall of the hollow column has an inner annular groove, and a limit block is slidably mounted in the inner annular groove. The top surface of the limit block is fixedly installed with the bottom end of the adjusting column. The upper end of the adjusting column is made of rubber. The cooperation between the inner annular groove and the limit block provides precise guidance and restriction for the sliding of the adjusting column in the hollow column. This not only ensures the smoothness and accuracy of the adjustment process, but also effectively prevents the adjusting column from shifting or falling off during the sliding process, thereby ensuring the overall stability and safety of the weighing machine.
[0014] Preferably, there are multiple bayonets, which are evenly distributed on the top surface of the auxiliary plate. This design provides users with more height adjustment options. Users can select the appropriate bayonet for engagement according to their actual needs, thereby achieving precise adjustment of the clamping device height. This design further enhances the adaptability and flexibility of the weighing machine.
[0015] This invention provides a fully automatic steel coil weighing machine based on PLC control. This PLC-controlled fully automatic steel coil weighing machine has the following advantages:
[0016] This PLC-controlled fully automatic steel coil weighing machine features convenient movement via casters, stable weighing via bolts and chassis, flexible adjustment components to adjust clamping height to accommodate different steel coil sizes, corrugated buffer pads to reduce impact and improve weighing accuracy, and arc-shaped clamping plates for secure gripping and to prevent slippage. PLC control ensures accurate data display. Attached Figure Description

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0024] like Figures 1-5As shown, this utility model provides a technical solution: a fully automatic steel coil weighing machine based on PLC control, including a base plate 1. Universal wheels 2 are fixedly installed at the bottom of the four corners of the base plate 1. By installing universal wheels 2 at the four corners of the base plate 1, the mobility and flexibility of the weighing machine are significantly enhanced. Whether within a workshop or during cross-regional transportation, the weighing machine can be easily moved and positioned quickly, improving work efficiency and convenience. Bolts 3 are threadedly connected to the base plate 1. A chassis 5 is fixedly installed at the bottom end of the bolts 3, and a knob 4 is fixedly installed at the top end of the bolts 3. The threaded connection of the bolts 3 and chassis 5, combined with the operation of the knob 4, allows the weighing machine to be quickly adjusted and fixed in position when stable weighing is required. A weighing platform 6 is provided above the base plate 1. A buffer pad 9 is fixedly installed on the bottom surface of the weighing platform 6. The bottom surface of the buffer pad 9 is fixedly installed on the top surface of the base plate 1. The outer wall of the buffer pad 9 has a corrugated design, and there are two buffer pads 9 arranged symmetrically. The corrugated design of the buffer pad 9 not only increases the contact area between the weighing platform 6 and the base plate 1, but also effectively absorbs the impact force generated when the steel coil is placed through its elastic properties. The two symmetrically arranged buffer pads further ensure the stability and balance during the weighing process, reduce the weighing error caused by vibration and impact, and improve the accuracy of weighing. The weighing platform 6 is connected to a display 8 via a connecting cable 7. A mounting rod 10 is fixedly installed on the top surface of the weighing platform 6, and an arc-shaped... The elastic clamping piece 11, an arc-shaped elastic clamping piece fixed to the weighing platform 6 by the mounting rod 10, provides a stable clamping force for the steel coil. Its arc-shaped design can better conform to the shape of the steel coil, ensuring that the steel coil will not slip or shift during the weighing process, thereby ensuring the stability and accuracy of the weighing. The display 8 is connected to the top surface of the base plate 1 through an adjustment assembly. The adjustment assembly includes an adjustment column 15, a hollow column 16 is slidably sleeved on the outside of the adjustment column 15, the bottom end of the hollow column 16 is fixedly installed to the top surface of the base plate 1, the inner wall of the hollow column 16 has an inner annular groove, and a limit block 18 is slidably installed in the inner annular groove. The top surface of the limit block 18 is fixedly installed to the bottom end of the adjustment column 15, and the upper end of the adjustment column 15 is made of rubber. The outer wall of the adjusting column 15 is fixedly installed with an installation block 17. The installation block 17 is movably connected to a locking rod 14 via a pin. The lower end of the locking rod 14 is engaged with a slot 13 opened on the top surface of the auxiliary plate 12. The bottom surface of the auxiliary plate 12 is fixedly installed with the top surface of the base plate 1. There are multiple slots 13, which are evenly distributed on the top surface of the auxiliary plate 12. The design of the adjusting component allows the height of the clamping device to be flexibly adjusted according to steel coils of different sizes. The position of the adjusting column 15 within the hollow column 16 is adjusted by sliding, and the locking action of the locking rod 14 and the slot 13 is used to achieve fixation. This process is simple and quick, and the adjustment range is wide, which can meet the weighing requirements of steel coils of various specifications, improving the versatility and flexibility of the weighing machine.
[0025] When using this PLC-controlled fully automatic steel coil weighing machine, firstly, the weighing machine is moved to the designated working position by the casters 2 installed at the four corners of the base plate 1. Then, the knob 4 is rotated to lower the bolt 3 until the base 5 is firmly in contact with the ground, ensuring the stability of the weighing machine during operation.
[0026] Next, based on the size of the steel coil to be weighed, the height of the clamping device is adjusted using the adjusting components: the position of the sliding adjusting column 15 within the hollow column 16, along with the cooperation of the inner annular groove and the limiting block 18, ensures the smoothness of the adjustment process. Once the appropriate height is reached, the clamping rod 14 is engaged with the corresponding slot 13 on the auxiliary plate 12 to fix the clamping device. During this adjustment, the multiple equally spaced slots 13 provide a wide adjustment range to meet the needs of steel coils of different sizes. Then, the steel coil is placed on the weighing platform 6. The two symmetrically arranged corrugated buffer pads 9 at the bottom of the weighing platform 6 effectively absorb the impact force when the steel coil is placed, ensuring the stability and accuracy of the weighing process. The weighing platform 6 transmits the weight signal to the PLC control system via the connecting cable 7 for processing. The processed weighing result is then sent to the display 8 via the connecting cable 7 for display.
[0027] During this process, the arc-shaped elastic clamping piece 11 is fixed on the weighing platform 6 by the mounting rod 10, providing a stable clamping force for the steel coil and preventing the steel coil from sliding or shifting during the weighing process. Finally, the weighing platform 6 can weigh the steel coil by controlling the PLC, and the value can be transmitted to the display 8 through the connecting line 7.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
