Technical Field

[0001] The utility model relates to the technical field of weighing and checking, in particular to a connection structure and a self-checking weighing device. Background Art

[0002] An electronic belt scale is an automatic weighing instrument that continuously weighs bulk materials on a conveyor belt without the need to subdivide the mass or interrupt the movement of the conveyor belt. As a measuring device for continuously weighing bulk materials on a conveyor belt, the electronic belt scale needs to be calibrated periodically to ensure that its measuring performance is within the allowable range.

[0003] The calibration methods include material calibration and simulated load calibration. Since the electronic hopper scale used for material calibration is greatly affected by production factors on the site, a simulated calibration method is usually used. The standard weights configured for simulated load calibration are loaded on the belt or metering roller of the belt conveyor, and then the force is transmitted to the weighing sensor through the scale frame. Therefore, the weight of the standard weights is susceptible to metering errors caused by belt slippage, deviation or deformation of the metering roller bracket. Utility Model Content

It includes an installation component 100, and the installation component 100 includes a calibration unit 101, a fixing unit 102, a protective enclosure 103 and a motion card slot 104. The calibration unit 101 is provided with a motion card slot 104, and the motion card slot 104 is provided with a protective enclosure 103. One end of the calibration unit 101 is provided with a fixing unit 102. The protective enclosure 103 of the telescopic structure on the calibration unit 101 can limit the calibration weight when it is in use. When performing daily maintenance work, the weight placement platform can also be better cleaned, which helps to further reduce the impact of errors.

[0035] A weighing tape 200 is provided with an installation assembly 100, and the weighing tape 200 includes a connecting bracket 201, a mounting rod 204 and a fixed block 205. The weighing tape 200 is provided with a connecting bracket 201, a mounting rod 204 is provided on the connecting bracket 201, and a fixed block 205 is provided on the mounting rod 204.

After the installation is completed, the weights used for verification are placed on the platform formed inside the protective enclosure 103 for verification.

[0037] Example 2

[0038] Reference Figure 1 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a connection structure to solve the problem that the weight of the standard weight is easily affected by the measurement error caused by the slipping, deviation or deformation of the metering roller bracket. It includes a weighing belt 200, on which the mounting assembly 100 is arranged. The weighing belt 200 includes a connecting bracket 201, a mounting connecting rod 204 and a fixed block 205. The weighing belt 200 is provided with a connecting bracket 201, a mounting connecting rod 204 is arranged on the connecting bracket 201, and a fixed block 205 is arranged on the mounting connecting rod 204. The connecting bracket 201 is provided with a supporting base 202, and a driving motor 203 is arranged between the connecting bracket 201 and the weighing belt 200. By arranging a calibration device on the non-working surface of the weighing belt 200, the weighing belt 200 can be kept in a continuous working state during the calibration work, thereby reducing the influence of the calibration on the work efficiency;

[0039] Preferably, at least three groups of mounting links 204 are arranged at equal intervals on the weighing tape 200, the positions of the mounting links 204 correspond to the positions of the weighing structures on the weighing tape 200, the size of the fixed block 205 matches the size of the linkage joint 102b, the height of the linkage joint 102b is smaller than the height of the movable slot 102a, and a length adjustment structure is arranged on the connecting bracket 201, and the size of the adjustment structure matches the size of the weighing tape 200. By arranging multiple groups of mounting links 204, more information can be collected for verification, and the connection tightness between the devices is improved by the fixed block 205 and the linkage joint 102b whose sizes match each other.

[0040] When in use, the weighing belt 200 is driven by the driving motor 203 to transport materials. While transporting materials, the transported materials can also be weighed to better obtain the weight data of the materials, which is convenient for subsequent processing.

[0041] Example 3

[0042] Reference Figure 3 to Figure 6, which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment solves the problem that the calibration device cannot be stored and is placed in the working environment for a long time, which affects the calibration accuracy. It includes a guide through hole 101a in the calibration unit 101, and a lifting slot 108 is opened in the calibration unit 101. One end of the guide through hole 101a is connected to the motion slot 104, and the other end of the guide through hole 101a is connected to the lifting slot 108. Through the mutual cooperation of the lifting slot 108, the motion slot 104 and the guide through hole 101a, the internal linkage structure maintains synchronization when moving. At the same time, the lifting slot 108 and the motion slot 104 with the same rising distance can provide higher supporting force after the structure is triggered, thereby ensuring the use effect of the device;

[0043] Preferably, the fixed unit 102 includes an active slot 102a, a linkage joint 102b, a linkage connecting rod 102c and a linkage top plate 102d. The fixed unit 102 is provided with an active slot 102a, and a linkage joint 102b is provided in the active slot 102a. A linkage connecting rod 102c is provided at one end of the linkage joint 102b, and a linkage top plate 102d is provided on the linkage connecting rod 102c. The linkage connecting rod 102b has the same structure but a smaller size and can move in the active slot 102a as a trigger mechanism of the structure. When the device as a whole is connected to the weighing device, under the action of gravity, the verification unit 101 will automatically move downward, and the linkage joint 102b will move upward inside the active slot 102a, thereby driving the linkage connecting rod 102c and the linkage top plate 102d at the lower end to move upward together, and the protective enclosure 103 is extended;

[0044] Furthermore, a linkage guide column 107 is provided at the upper end of the linkage top plate 102d, an extension bracket 106 is provided at one end of the linkage guide column 107, a linkage bracket 105 is provided on the extension bracket 106, and the linkage bracket 105 is provided on the protective enclosure 103 through the linkage block 103a. The linkage guide column 107 interconnected with the linkage top plate 102d allows the protective enclosure 103 at the lower end to move together with the linkage top plate 102d at the upper end, so that the overall movement of the device is more consistent;

[0045] Furthermore, four mutually symmetrical linkage blocks 103a and extension brackets 106 are provided on the protective enclosure 103. The linkage blocks 103a and the extension brackets 106 are staggered with each other, and the size of the linkage guide column 107 is adapted to the size of the guide through hole 101a. The four mutually symmetrical linkage blocks 103a and the extension brackets 106 not only make the rising of the protective enclosure 103 smoother, but also reduce the deviation of the internal structure during movement, thereby extending its service life.

[0046] When in use, when the fixed block 205 is connected to the fixed unit 102, the protruding part of the fixed block 205 will be connected to the internal movable slot 102a. When the force provided to the verification unit 101 during installation disappears, the inclined surface set at the upper end of the movable slot 102a will contact the inclined surface at the upper end of the fixed block 205 to complete the fixing work. When the linkage joint 102b moves upward, it will drive the linkage top plate 102d at the lower end to move upward in the lifting slot 108. When the linkage top plate 102d moves upward, it will also drive the extension bracket 106 to move upward through the linkage guide column 107, so that the protective enclosure 103 fixedly connected thereto is ejected from the movable slot 104, and cooperates with the verification unit 101 to form a platform for placing the verification weights, which is used to perform verification work on the weighing unit.
