Description

Technical Field

[0001] This utility model relates to the field of filling and weighing technology, and in particular to a device for calibrating a filling scale. Background Technology

[0002] In industries such as food, manufacturing, pharmaceuticals, and chemicals, filling scales are key weighing instruments that accurately fill containers with liquids according to set weights. Through the coordinated operation of the liquid filling gun, weighing system, and control system, they ensure the accuracy and efficiency of liquid filling. To ensure the accuracy of the weighing system, regular calibration is indispensable, and weights, as the standard calibration tool, play a core role in this process.

[0003] However, current filling scales have some problems with their structural design and weight storage. The sensors, pipes, and other components located at the top and bottom of the containers severely limit the storage space for weights. The tops of the containers are mostly spherical, and even if there is some space, the area available for placing weights is extremely limited, and there are safety hazards during placement, as weights can easily slip and cause accidents. When there are not enough weights, calibration can only be completed by using water as a substitute multiple times. This substitute calibration method not only consumes a lot of the customer's production time and the time of the on-site engineers, reducing production efficiency, but also causes serious waste of water resources, increases the company's operating costs, and cannot guarantee the accuracy and reliability of the calibration results.

[0004] To address this issue, a calibration device for filling scales is proposed to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems by providing a calibration device for filling scales. This utility model, through the inclusion of a load plate and a support frame, provides a dedicated flat surface for placing weights. Compared to existing spherical structures on the top of the can and small, unfixed areas on the bottom, it significantly increases the area available for weight storage, accommodating more weights, reducing the need for water-based calibration, saving time, and improving efficiency. To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0006] According to one aspect of the present invention, a device for calibrating a filling scale is provided, including a weighing tank, a plurality of water injection pipes on the top of the weighing tank, three support legs evenly distributed at the lower end of the weighing tank, a plurality of support rods evenly distributed on the top of the weighing tank, and a load plate commonly provided on the top of the plurality of support rods. The load plate is used to place weights, the top of the load plate is treated with anti-slip treatment, and the load plate has a placement opening that cooperates with the plurality of water injection pipes. A support frame is provided between the three support legs, and a connecting component is provided between the load plate and the plurality of support rods.

[0007] Preferably, the load plate and the multiple support rods are designed separately. The connecting assembly includes multiple connecting rods disposed at the bottom of the load plate, and each connecting rod has a limiting ring at its lower end. Each limiting ring has a limiting groove. Each support rod has an annular groove on its outer circumference, and each annular groove has a limiting rod that cooperates with the limiting groove.

[0008] Preferably, each of the support rods is provided with a magnetic block 1 at its top, and the load plate is provided with multiple placement slots at its bottom, and each placement slot is provided with a magnetic block 2, and the multiple magnetic blocks 1 and magnetic blocks 2 cooperate with each other.

[0009] Preferably, the support frame consists of three bearing plates, which are stacked and spliced ​​together. Each bearing plate has a mounting ring at both ends that cooperates with the support foot. The inner ring of each mounting ring is treated with anti-slip treatment, and each mounting ring has an opening.

[0010] Preferably, each of the bearing plates is provided with a splicing plate, and the three splicing plates are of different heights, and the three splicing plates are spliced ​​together on the same plane.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0019] Please see Figures 1 to 4 This utility model provides a device for calibrating a filling scale, the technical solution of which is as follows:

[0020] The device includes a weighing tank 1, with multiple water injection pipes 2 on the top, three support legs 3 evenly distributed at the bottom, and multiple support rods 4 evenly distributed on the top. A load plate 5 is provided on the top of each support rod 4. The load plate 5 is used to hold weights, and its top is treated with an anti-slip surface to prevent weights from sliding and falling. This solves the problems of unsafe placement on the top of the tank and the safety hazards caused by the unsecured triangular plate at the bottom, ensuring the safety of personnel and equipment during calibration. The load plate 5 has a placement opening 6 that mates with the multiple water injection pipes 2. A support frame 7 is provided between the three support legs 3, and a connecting assembly is provided between the load plate 5 and the multiple support rods 4.

[0021] By setting evenly distributed support rods 4 and load plates 5 on the top of the weighing tank 1, the load plates 5 provide a dedicated flat surface for placing weights. Compared with the existing spherical structure on the top of the tank and the small unfixed plate at the bottom, this significantly increases the area where weights can be stored, accommodating more weights, reducing the need for water to replace calibration, saving production and engineering time, and avoiding water waste. By setting connecting components, a flexible assembly relationship is established between the load plates 5 and the filling scale, enabling quick disassembly and assembly of the load plates 5 and the filling scale. When the load plates 5 wear out due to long-term placement of weights, the anti-slip treatment fails, or the structure deforms due to accidental collisions, the staff does not need to disassemble the entire filling scale. They can easily remove the load plates 5 for replacement or repair by simply operating the connecting components, simplifying the maintenance process and improving efficiency.

[0022] The load plate 5 and the multiple support rods 4 are designed separately. The connecting assembly includes multiple connecting rods 8 set at the bottom of the load plate 5, and each connecting rod 8 is provided with a limiting ring 9 at its lower end. Each limiting ring 9 is provided with a limiting groove 10. Each support rod 4 is provided with an annular groove 11 on its outer circumference, and each annular groove 11 is provided with a limiting rod 12 that cooperates with the limiting groove 10.

[0023] The load plate 5 and support rod 4 adopt a separate design, and are equipped with a connecting assembly consisting of a connecting rod 8, a limiting ring 9, a limiting groove 10, a ring groove 11, and a limiting rod 12. Through the cooperation of the limiting rod 12 and the limiting groove 10, the assembly or disassembly of the load plate 5 and support rod 4 can be completed quickly without complicated tools. Compared with the traditional fixed structure, this greatly simplifies the process of replacing and maintaining the load plate 5, reduces the difficulty of operation, saves manpower and time costs, and facilitates daily equipment maintenance and component replacement.

[0024] The structure of the limiting rod 12 embedded in the limiting groove 10 and the ring groove 11 forms a stable limiting relationship after the load plate 5 is connected to the support rod 4, effectively limiting the displacement of the load plate 5 in the horizontal direction. Combined with the anti-slip treatment on the top of the load plate 5, the structure can remain stable even if a large number of weights are placed or it is slightly disturbed by external forces, ensuring that the position of the weights is fixed during the calibration process and improving the accuracy of weighing and measurement.

[0025] Each of the support rods 4 is equipped with a magnetic block 13 at its top, and the load plate 5 has multiple placement slots 14 at its bottom, with a magnetic block 25 in each slot. The magnetic blocks 13 and 25 cooperate with each other. During the installation of the load plate 5, the magnetic blocks 13 and 25 attract each other, which can automatically position the load plate 5. The operator does not need to precisely align the limiting rod 12 and the limiting slot 10, etc. The magnetic attraction can quickly place the load plate 5 in the correct position, reducing assembly difficulty and improving installation efficiency. At the same time, the cooperation of the magnetic blocks 13 and 25 adds magnetic connection force to the mechanical connection between the limiting rod 12 and the limiting slot 10, further strengthening the connection strength between the load plate 5 and the support rod 4.

[0026] The support frame 7 is composed of three bearing plates 701, which are stacked and spliced ​​together. Each bearing plate 701 has a mounting ring 702 at both ends that cooperates with the support foot 3. The inner ring of each mounting ring 702 is treated with anti-slip treatment, and each mounting ring 702 has an opening 703.

[0027] The support frame 7 is composed of three load-bearing plates 701 stacked together to form a stable triangular support structure. Compared with a single support component, it greatly enhances the support force of the symmetrical weighing tank 1. When a large number of weights are placed for calibration, the pressure of the weighing tank 1 can be effectively distributed, reducing the risk of tilting and shaking caused by uneven force, and providing a stable support environment for the accurate weighing of weights.

[0028] The mounting rings 702 at both ends of each support plate 701 cooperate with the support legs 3. Utilizing the opening design 703, the mounting rings 702 can be quickly fitted onto the support legs 3 to complete the installation without complicated tools or cumbersome operations, greatly improving installation efficiency. At the same time, the anti-slip treatment of the inner ring of the mounting ring 702 ensures a tight fit with the support legs 3, preventing the support frame 7 from sliding or shifting during use and ensuring its supporting effect. This structure is also suitable for support legs 3 of different specifications and sizes. By adjusting the position and tightness of the mounting rings 702, it can be adapted to various models of filling scales, enhancing the equipment's versatility.

[0029] Each of the three support plates 701 is provided with a splicing plate 704, and the three splicing plates 704 are of different heights. After splicing, the three splicing plates 704 are on the same plane. The design of splicing plates 704 of different heights on the support plate 701, which are on the same plane after splicing, forms a stepped interlocking structure when the three support plates 701 are spliced. Compared with ordinary flat splicing, the stepped splicing greatly increases the contact area and friction between the support plates 701, which can effectively disperse the pressure and shear force generated by the weights on the support frame 7 during the calibration process, prevent the support plates 701 from being misaligned or sliding under force, further enhance the overall stability of the support frame 7, provide more reliable support for the weighing tank 1 and the weights, and ensure calibration accuracy.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
