Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a fast weighing mechanism for a large-scale baler. Background Art

[0002] With the continuous development of mechanical manufacturing and intelligent control technology, large-scale balers, as a common logistics processing equipment, play an important role in the compression and weighing of goods. As an important component of large-scale balers, the performance of the rapid weighing mechanism directly affects the operating efficiency of the logistics system and the accuracy of cargo handling. However, the existing baler rapid weighing technology still has many shortcomings in practical applications, mainly reflected in low operating efficiency, low weighing accuracy and poor equipment operation stability.

[0003] Traditional large-scale balers usually use a single hydraulic transmission system to drive the pressure plate to compress and shape the goods, but they often face problems such as unstable sliding and uneven pressing force during operation, resulting in irregular shapes of the goods after pressing, which increases the difficulty of subsequent transportation and storage. At the same time, most existing weighing devices are based on single-point or small-point weighing sensors for measurement, lacking the fusion processing of multi-point weighing data, resulting in poor accuracy of weighing results and difficulty in meeting high-standard logistics requirements.

[0004] In addition, the pulley guide rail system of traditional equipment is mostly a simple mechanical connection method, which is prone to friction and wear, resulting in high maintenance frequency and short service life of the equipment. The design of the feeding push plate is also mostly fixed, lacking flexibility and durability. The push plate is prone to deformation or damage during high-frequency operation, further reducing the efficiency and stability of the equipment.

[0005] In recent years, with the development of high-precision sensor technology and intelligent control algorithms, multi-point weighing and dynamic signal processing technology have gradually been applied in industrial equipment, but they have not yet been widely used in the field of large-scale balers. In addition, the automatic lubrication technology of the pulley guide rail and the optimized design of the pressure plate have not been fully combined, resulting in difficulty in significantly improving the stability and service life of the equipment.

[0006] Therefore, there is an urgent need for a large-scale baler rapid weighing mechanism that integrates high-precision multi-point weighing sensors, durable pulley guide systems and efficient hydraulic transmission mechanisms, which can solve the shortcomings of the existing technology and improve the efficiency and accuracy of cargo pressing and weighing, thereby meeting the needs of modern logistics for efficient and intelligent equipment. Summary of the invention

[0007] The object of the present invention is to provide a fast weighing mechanism for a large-scale baler, which realizes fast pressing, accurate weighing and efficient operation of goods by integrating an efficient hydraulic transmission mechanism, a pulley guide rail system and a multi-point weighing device, and solves the problems of low operating efficiency, insufficient weighing accuracy and poor equipment stability in the prior art. The X-axis refers to the horizontal lateral direction of the baling frame, that is, the axial direction corresponding to the goods during the lateral pressing process. The X-axis pressure plate (side pressure plate) moves in this direction to squeeze the goods from the side onto the shell of the frame to flatten one side of the goods. The Y-axis refers to the vertical direction, that is, the axial direction perpendicular to the ground. The Y-axis pressure plate (top pressure plate) moves in this direction to vertically press the goods from the top to flatten the top surface of the goods. The Z-axis refers to the horizontal longitudinal direction of the baling frame, which is perpendicular to the X-axis. The Z-axis pressure plate (bottom pressure plate) moves in this direction to squeeze the goods from the other side to flatten the front and back sides of the goods.

[0008] To achieve the above-mentioned purpose, the present invention provides a large-scale baler rapid weighing mechanism, including a feeding device, a transmission mechanism, a pulley guide rail system, a baling frame and a weighing device. The feeding device includes a feeding port and a feeding push plate, which is arranged below the feeding port and pushes the goods into the baling frame through the transmission mechanism. The baling frame includes a Y-axis pressing plate, an X-axis pressing plate and a Z-axis pressing plate, wherein the Y-axis pressing plate is arranged at the top of the baling frame and is used to press the goods in the Y-axis direction; the X-axis pressing plate and the Z-axis pressing plate are arranged in the baling frame and respectively press the goods in the lateral and bottom directions, thereby completing the flattening of the six sides of the goods. The pulley guide rail system includes a pulley and a frame guide rail arranged on the back of the pressing plate, and the pulley is embedded in the frame guide rail to ensure the stability and linear motion of the pressing plate during operation. The weighing device is installed at the bottom of the baling frame and is used to accurately weigh the goods that have been pressed, and the weighing result is output to the control system through the signal processing module.

[0009] The feeding push plate is connected to the transmission shaft with a wear-resistant flange. The surface of the push plate is hardened and has an impact-resistant structure to ensure long-term stable operation. The pulley is made of high-strength wear-resistant material and is connected to the pressure plate through a sealed bearing. The bearing is equipped with an automatic lubrication device to effectively reduce friction and extend its service life. The hydraulic transmission mechanism is connected to the control system through a pressure sensor, which can monitor the thrust of the hydraulic cylinder in real time and dynamically adjust the pressing force of the pressure plate according to the material and weight of the goods to achieve a more accurate pressing effect.

[0010] The present invention also integrates multiple weighing sensors in the weighing device. The sensors are all installed at the key stress points at the bottom of the packaging frame. The signal processing module realizes multi-point data fusion to improve the weighing accuracy. In addition, the extrusion direction of the X-axis pressure plate is parallel to the side wall of the shell, and the surface of the side pressure plate is provided with anti-slip texture to prevent the goods from sliding during the extrusion process; after the pressing is completed, the goods are pressed into a regular cuboid with six completely flat surfaces, thereby improving the efficiency of subsequent storage and transportation.

[0011] Through the above technical scheme, the present invention effectively improves the efficiency and accuracy of large-scale balers in the cargo pressing and weighing stages, and at the same time improves the stability and service life of the equipment through modular design, which is suitable for the efficient cargo handling needs in modern logistics systems.

[0012] Furthermore, the present invention performs multi-level optimization on the overall performance and functional requirements of the fast weighing mechanism of a large-scale baler to ensure that it can operate efficiently and stably in industrial production.

[0013] In order to improve the running stability and pressing effect of the pressing plate, the pulley guide rail system adopts a combination design of high-strength guide rails and wear-resistant pulleys. The guide rails are heat-treated to enhance the surface hardness and wear resistance. The pulleys are built-in sealed bearings and equipped with automatic lubrication devices to ensure that the pulleys can remain stable for a long time under high-load operation, reducing wear and resistance. The precise matching of the guide rails and pulleys can effectively prevent the displacement of the pressing plate during movement.

[0014] Furthermore, the surface of the X-axis pressing plate is coated with a non-slip composite material, which has high strength and high wear resistance, and is designed with a non-slip texture, which can enhance the contact friction between the goods and the pressing plate during the pressing process, thereby preventing the goods from slipping during the pressing process. The integrated design of the transmission structure and hydraulic system of the X-axis pressing plate can accurately transmit the pressing force and improve the pressing efficiency.

[0015] To ensure the accuracy and adaptability of the weighing system, the weighing device integrates multiple sets of high-sensitivity weighing sensors, which are installed at the key force-bearing positions at the bottom of the packaging frame and perform real-time data acquisition and analysis through the signal processing module. The signal processing module uses high-frequency filtering technology combined with fuzzy logic algorithms to filter out environmental noise interference and achieve high-precision measurement of cargo weight. The weighing data can be transmitted to the control system in real time for quality monitoring of the production line.

[0016] Preferably, the packaging frame adopts a modular structure design, and the functional components are connected by bolts and fixed by positioning pins, which can not only ensure the strength of the overall frame, but also facilitate equipment transportation, installation and maintenance. The frame material is selected from lightweight high-strength steel alloy, and the structure is optimized through finite element analysis to ensure the stability and deformation resistance of the frame during operation.

[0017] Furthermore, the multi-axis synchronous control of the pressing plate is achieved through an independent hydraulic cylinder, which is equipped with a high-precision position sensor that can monitor the position and angle of the pressing plate in real time to ensure that the goods are evenly stressed during the pressing process. The pressed goods are in the form of a regular rectangular parallelepiped with six completely flat surfaces, which is convenient for subsequent packaging, transportation and storage.

[0018] The power transmission system is connected to the transmission shaft through a hydraulic cylinder. The surface of the push plate is hardened and an impact-resistant structure is added to enhance the durability and reliability of the equipment in high-frequency use. The hydraulic transmission system dynamically adjusts the push plate thrust through a built-in pressure sensor to meet the pressing needs of different types of goods.

[0019] Through the above-mentioned design optimization, the large-scale baler rapid weighing mechanism of the present invention can significantly improve the efficiency of the industrial pressing and weighing processes, enhance the stability and adaptability of the equipment, and meet the needs of modern industrial production for efficient and intelligent equipment.
