Description

Technical Field

[0001] The present application relates to the technical field of a weighing instrument, and in particular to a steel coil buffer scale. Background Art

[0002] The steel coil buffer scale is a scale specially used for weighing the quality of steel coils. It is mainly used in steel coil packaging and conveying production lines and steel coil shearing and processing production lines.

[0003] The steel coil buffer scale includes a mounting base, a weighing sensor assembly mounted on the mounting base, and a carrier arranged on the weighing sensor assembly. In the case of a weighing system using multiple weighing sensor assemblies (including 2 or more), if one of the weighing sensor assemblies and the carrier is not properly installed when unloaded, there is a gap between the weighing sensor assembly and the carrier, so that there is no direct force relationship between the two, which will cause the weighing sensor to not work during the weighing process, and the data displayed by the weighing is inaccurate.

[0004] In the prior art, when installing a weighing sensor assembly, the installer usually adjusts the height by adding or reducing a thin pad in the gap between the weighing sensor assembly and the carrier, so that each weighing sensor assembly and the carrier can have a direct force relationship, and when adjusting the height, it is necessary to ensure that the height of each weighing sensor is consistent, which requires the installer to continuously and strictly adjust the height of each weighing sensor.

[0005] With respect to the above-mentioned related technologies, the inventors believe that the height of the sensor assembly is adjusted by adding or reducing thin pads, and the adjustment process is inconvenient and has high requirements on the installers. Utility Model Content

[0006] In order to solve the problem that the adjustment process of the sensor assembly height is inconvenient and has high requirements for the installer, the present application provides a steel coil buffer scale.

[0007] The present application provides a steel coil buffer scale adopting the following technical solution:

[0008] A steel coil buffer scale comprises a mounting base, a weighing platform, and at least three sensor assemblies mounted on the top of the mounting base and used to support the weighing platform. The sensor assembly comprises a weighing sensor mounted on the mounting base, a pressure head seat for abutting the ball head of the weighing sensor, a fixed shell mounted on the bottom of the weighing platform and used for vertical sliding of the pressure head seat, and an elastic member supported between the pressure head seat and the fixed shell.

[0009] By adopting the above technical solution, when the steel coil buffer scale is weighing, the elastic member can transmit the pressure of the fixed shell to the pressure head seat. When the steel coil buffer scale is initially installed, if there is inconsistency in the installation height of the sensor assembly, the elastic member can automatically adjust the gap between the top surface of the pressure head seat and the fixed shell, so that multiple sensor assemblies can be evenly stressed. The above-mentioned elastic member is arranged between the fixed shell and the pressure head seat, and the height is automatically adjusted by the elastic member. The adjustment process is relatively simple and the requirements for the installer are not high.

[0010] Optionally, the top of the pressure head seat has a limit plate, the fixed shell has a limit cavity for allowing the limit plate to slide down, the fixed shell is also provided with a limit through hole connected to the limit cavity and used for the pressure head seat to extend downward, and the elastic member is arranged in the limit cavity.

[0011] By adopting the above technical solution, the pressure head seat can only slide up and down in the limiting cavity under the limiting effect of the fixed shell on the limiting plate, thereby improving the stability of the pressure head seat of the sensor assembly in sliding up and down. In addition, the elastic member is arranged in the limiting cavity, reducing the probability of damage to the elastic member.

[0012] Optionally, the fixed shell includes an upper fixed seat installed on the bottom surface of the weighing platform and a fixed pressure plate installed on the upper fixed seat by bolts; the limiting cavity includes a first groove body arranged on the bottom surface of the upper fixed seat and a second groove body arranged on the top surface of the fixed pressure plate, and the limiting through hole is arranged on the fixed pressure plate.

[0013] By adopting the above technical solution, the limiting cavity of the fixed shell is composed of a first slot body and a second slot body. Compared with a structure with only one slot body, the first slot body and the second slot body can jointly share the pressure of the weighing platform on the weighing sensor, thereby making the structural strength of the fixed shell higher.

[0014] Optionally, the elastic member is an elastic disc spring; the outer diameter of the elastic member gradually decreases in the direction away from the weighing sensor; the axis of the elastic member is coaxially arranged with the vertical axis of the ball head of the weighing sensor.

[0015] By adopting the above technical solution, a structural form of an elastic member is disclosed. The elastic disc spring has good elastic performance. When the steel coil buffer scale is unloaded, the elastic disc spring can naturally extend and abut against the top surface of the pressure head seat and the inner bottom surface of the upper fixed seat, respectively, to transmit the pressure of the weighing platform to the weighing sensor. In addition, the installer only needs to place the elastic disc spring in the limit cavity during installation, and the installation process is relatively simple.

[0016] Optionally, the elastic member is formed by stacking at least two elastic disc springs in a vertical direction; the outer diameter of the elastic member gradually decreases in a direction away from the weighing sensor; and the axis of the elastic member is coaxially arranged with the vertical axis of the ball head of the weighing sensor.

[0017] By adopting the above technical solution, another structural form of an elastic member is disclosed. The elastic member is formed by stacking a plurality of elastic disc springs. Compared with the arrangement of a single elastic disc spring, the plurality of disc springs can have a greater elastic force, and the force transmission effect between the weighing platform and the weighing sensor is more ideal.

[0018] Optionally, a limiting ring groove for mounting the lower end of the elastic member is provided on the bottom surface of the limiting plate.

[0019] By adopting the above technical solution, when the steel coil buffer scale is weighing, the elastic disc spring installed in the limit ring groove is not easy to shake, the weighing sensor is more evenly stressed, and the steel coil buffer scale weighing effect is more accurate.

[0020] Optionally, a safety limit structure is also included; the safety limit structure includes a sliding through hole passing through the upper and lower bottom surfaces of the weighing platform, a limit guide column slidably installed on the sliding through hole, an abutment plate arranged on the top surface of the weighing platform and used to cover the sliding through hole, and a mounting seat arranged on the mounting base for installing the limit guide column.

[0021] By adopting the above technical solution, when the steel coil buffer scale is weighing, the weighing platform can slide up and down along the limit guide pillar, reducing the probability of the weighing platform tipping over due to uneven placement of products on the weighing platform. In addition, an abutment plate is provided. When the weight of the product is too large, the top surface of the limit guide pillar can abut against the abutment plate, and the weighing platform will not continue to press down, reducing the probability of damage to the weighing sensor due to excessive product weight.

[0022] Optionally, the weighing platform has an insulating chamber therein; and the side wall of the weighing platform has a first water inlet and a first water outlet that penetrate into the insulating chamber.

[0023] By adopting the above technical solution, the steel coil is in a high temperature state when it is just produced. An insulating chamber is provided and filled with flowing water, which can reduce the overall heat of the steel coil buffer scale and effectively reduce the probability of high temperature damaging the steel coil buffer scale.

[0024] Optionally, the outer side of the sensor assembly is covered with an insulating water jacket; the top surface of the insulating water jacket is provided with an upper through hole for the sensor assembly to pass through.

[0025] By adopting the above technical solution, high temperature may cause the weighing sensor to weigh inaccurately, and the insulating water jacket can reduce the temperature of the weighing sensor assembly and reduce the influence of high temperature on the weighing effect of the weighing sensor.

[0026] Optionally, a support seat is provided on the top surface of the weighing platform, and the support seat has symmetrically arranged abutment slopes for supporting the steel coil.

[0027] By adopting the above technical solution, the support seat can support and limit the steel coil, so that when the steel coil buffer scale weighs the steel coil, the steel coil is placed more stably on the weighing platform.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. A steel coil buffer scale, by installing an elastic member in the gap between the top surface of the pressure head seat and the fixed shell, the elastic member can automatically adjust the gap height, and when the steel coil buffer scale is unloaded, multiple sensor components can be evenly stressed; the elastic member is arranged between the fixed shell and the pressure head seat, and the height is automatically adjusted by the elastic member, the adjustment process is relatively simple, and the requirements for the installation personnel are not high;

[0030] 2. By setting up a safety limit structure, the weighing platform can slide up and down along the limit guide column when the steel coil buffer scale is weighing, reducing the probability of the weighing platform tipping over due to uneven placement of products on the weighing platform; and setting up an abutment plate reduces the probability of damage to the weighing sensor due to excessive product weight;

[0031] 3. By setting up a heat-insulating chamber and a heat-insulating water jacket, the damage to the steel coil buffer scale caused by the height is reduced, and the influence of high temperature on the weighing effect of the weighing sensor is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-6 This application is described in further detail.

[0040] The embodiment of the present application discloses a steel coil platform scale.

[0041] Example 1

[0042] Reference Figure 1 A steel coil buffer scale comprises a mounting base 1, a weighing platform 2 for placing the steel coil, and a sensor assembly 3 arranged on the mounting base 1 for supporting the weighing platform 2.

[0043] Reference Figure 1 The mounting base 1 is a cubic base. The mounting base 1 is cast by concrete. When casting the mounting base 1, a mounting bolt 11 is embedded in the mounting base 1, and a part of the screw of the mounting bolt 11 extends out of the top surface of the mounting base 1. The top surface of the mounting base 1 is provided with a plurality of mounting plates 12 threadedly matched with the mounting bolt 11.

[0044] Reference Figure 2 The weighing platform 2 includes beams 21 symmetrically located on both sides above the mounting base 1, a connecting portion 22 connecting the two beams 21, and a load-bearing portion 23 arranged on the top surfaces of the beams 21 and the connecting portion 22. Both the beams 21 and the connecting portion 22 are hollow structures, and the hollow structures are connected to each other to form a heat-insulating chamber 24.

[0045] Reference Figure 2 and Figure 3One end of the sensor assembly 3 is connected to the mounting base 1, and the other end of the sensor assembly 3 is connected to the beam portion 21. The sensor assembly 3 includes a weighing sensor 31 mounted on the mounting base 1, a pressure head seat 32 for the ball head of the weighing sensor 31 to abut, a fixed housing 33 mounted on the bottom of the beam portion 21 of the weighing platform 2, and an elastic member 34.

[0046] Reference Figure 2 and Figure 3 In this embodiment, there are four sensor assemblies 3 arranged at four corners of the mounting base 1 , so that the weighing platform 2 arranged on the sensor assemblies 3 is more stable.

[0047] Reference Figure 2 and Figure 3 The bottom surface of the weighing sensor 31 is provided with a lower fixing seat 311, and the lower fixing seat 311 is fixedly connected to the weighing sensor 31 by bolts. The lower fixing seat 311 is welded to the mounting plate 12 on the mounting base 1, so that the weighing sensor 31 is fixed on the mounting base 1.

[0048] Reference Figure 2 and Figure 3 The fixed housing 33 includes an upper fixed seat 331 welded to the bottom surface of the beam portion 21 and a fixed pressure plate 332 installed on the upper fixed seat 331 by bolts. The fixed housing 33 has a limiting cavity 333, which includes a first slot 3331 opened on the upper fixed seat 331 and opening downward, and a second slot 3332 opened on the fixed pressure plate 332 and opening upward. The horizontal cross-section size of the first slot 3331 and the second slot 3332 is equal. The fixed pressure plate 332 is provided with a limiting through hole 334 penetrating the upper and lower bottom surfaces on the bottom surface of the second slot 3332, and the diameter of the limiting through hole 334 is smaller than the cross-section size of the second slot 3332.

[0049] Reference Figure 2 and Figure 3 The pressure head seat 32 is vertically slidably installed in the limiting cavity 333 of the fixed shell 33, and a part of the pressure head seat 32 is penetrated by a limiting through hole 334 and extends out of the bottom surface of the fixed pressure plate 332. The pressure head seat 32 abuts against the ball head of the weighing sensor 31, and the bottom surface of the pressure head seat 32 is provided with an arrangement groove 321 for the ball head of the weighing sensor 31 to be embedded. The top of the pressure head seat 32 is provided with a limiting plate 322, and the limiting plate 322 is a square plate. The limiting plate 322 is located in the limiting cavity 333, and the size of the limiting plate 322 is adapted to the second slot body 3332. The fixed pressure plate 332 limits the limiting plate 322, so that the pressure head seat 32 cannot escape from the limiting cavity 333.

[0050] Reference Figure 2 and Figure 3The elastic member 34 is arranged in the limiting cavity 333, and the elastic member 34 is supported between the top surface of the limiting plate 322 and the upper fixing seat 331, so that there is an elastic gap 35 between the limiting plate 322 and the upper fixing seat 331. When the steel coil buffer scale is unloaded and the weighing platform 2 is pressed on the sensor assembly 3, the elastic gap 35 can automatically adjust its height as the elastic member 34 is compressed.

[0051] Reference Figure 3 In this embodiment, the elastic member 34 is an elastic disc spring. The axis of the elastic disc spring is coaxially arranged with the vertical axis of the ball head of the weighing sensor 31, and the outer diameter of the elastic disc spring gradually decreases in the direction away from the weighing sensor 31. The bottom surface of the limiting plate 322 is provided with a limiting ring groove 323 for mounting the lower end of the elastic disc spring. The above structure makes the elastic disc spring more stably arranged in the limiting cavity 333.

[0052] Reference Figure 2 and Figure 4 The steel coil buffer scale is also provided with a safety limit structure, which includes a sliding through hole 25 penetrating the upper and lower bottom surfaces of the weighing platform 2, a limit guide column 4 slidably mounted on the sliding through hole 25, an abutment plate 5 arranged on the top surface of the weighing platform 2 and used to cover the sliding through hole 25, and a mounting seat 6 arranged on the mounting base 1 for mounting the limit guide column 4. The mounting seat 6 is welded to the mounting plate 12 of the mounting base 1. The limit guide column 4 is a square column, one end of the limit guide column 4 is located in the sliding through hole 25, and the other end of the limit guide column 4 is welded to the mounting seat 6. The sliding through hole 25 is a square hole adapted to the limit guide column 4, and the sliding through hole 25 is not connected to the heat insulation chamber 24. The abutment plate 5 is mounted on the top surface of the weighing platform 2 by screws.

[0053] Reference Figure 2 and Figure 4 When the steel coil buffer scale is unloaded, there is a certain gap between the top surface of the limit guide post 4 and the abutment plate 5. When the steel coil placed on the weighing platform 2 is too heavy, the weighing platform 2 can move downward along the limit guide post 4, and the top surface of the limit guide post 4 abuts against the abutment plate 5, so as to reduce the probability of damage to the sensor assembly 3 due to the overweight of the steel coil. In addition, the limit guide post 4 can guide the weighing platform 2, so that the weighing platform 2 can only move up and down along the limit guide post 4, reducing the probability of the weighing platform 2 tipping over.

[0054] Reference Figure 2 and Figure 4 In this embodiment, two safety limit structures are provided, which are symmetrically arranged on both sides of the weighing platform 2.

[0055] Reference Figure 2In order to reduce the damage of the high temperature of the steel coil to the steel coil buffer scale, the weighing platform 2 is provided with a first water inlet 211 penetrating into the insulation chamber 24 on the side wall of one of the beam parts 21, and the weighing platform 2 is provided with a first water outlet 212 penetrating into the insulation chamber 24 and connected with the water inlet on the side wall of the other beam part 21, and flowing water is injected into the insulation chamber 24 to take away the heat of the steel coil buffer scale.

[0056] Reference Figure 5 The outer side of the sensor assembly 3 is covered with an insulating water jacket 7, which is a hollow square box with an opening at the lower end. The insulating water jacket 7 is provided with a second water inlet 71 and a second water outlet 72 connected to the second water inlet 71, so that the wall thickness of the insulating water jacket 7 is filled with flowing cold water to reduce the influence of high temperature on the weighing effect of the weighing sensor 31. The top surface of the insulating water jacket 7 is provided with an upper through hole 73 for the sensor assembly 3 to pass through.

[0057] Reference Figure 1 The top surface of the weighing platform 2 is also provided with four support seats 26, and every two adjacent support seats 26 have abutment slopes 261 arranged symmetrically and used to support the steel coil, and the abutment slopes 261 can be tangent to the outer wall of the steel coil.

[0058] Combination Figures 1 to 5 The implementation principle of a steel coil buffer scale in this embodiment is: the elastic disc spring can transmit the pressure of the weighing platform 2 to the weighing sensor 31; when the steel coil buffer scale is unloaded, the weighing platform 2 compresses the elastic disc spring, and the elastic gap 35 can automatically adjust the height with the compression of the elastic disc spring, so that the weighing platform 2 exerts pressure on the four sensor components 3, and the pressures are equal.

[0059] Example 2

[0060] Compared with the steel coil buffer scale in the first embodiment, the steel coil buffer scale in the present embodiment has the same structure as the steel coil buffer scale in the first embodiment except that the structure of the elastic member 34 is different.

[0061] Reference Figure 6 In this embodiment, the elastic member 34 is formed by stacking two elastic disc springs in the vertical direction. The axis of the elastic disc spring is coaxially arranged with the vertical axis of the ball head of the weighing sensor 31, and the outer diameter of the elastic disc spring gradually decreases in the direction away from the weighing sensor 31.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
