Description

Technical Field

[0001] The utility model relates to the technical field of calibration equipment, in particular to an automatic weight calibration device. Background Art

[0002] A weight calibration device is a device or tool used to inspect, calibrate, or verify the accuracy of measuring equipment. Weights, as standard objects of known mass, play a key role in calibrating and verifying measuring equipment. Electronic belt scales are commonly used in industries such as tobacco, chemicals, and logistics. In particular, in tobacco shred production lines, electronic belt scales are typically used to weigh tobacco leaves, shredded leaves, shredded stems, and flakes. The accuracy of electronic belt scales directly impacts the quality of tobacco product processing, so they require regular calibration to ensure accurate measurement.

[0003] Currently, the calibration of electronic belt scales is primarily a manual operation, requiring the collaboration of two or more people. Furthermore, a single electronic belt scale often needs to be calibrated for several different frequency and speed conditions, placing a high workload on the calibrators. This is especially true when the electronic scale is located at a high position. Operation poses significant safety risks, including the risk of the weights falling from a height due to hand slippage. Furthermore, calibration is difficult to complete. While there are also devices that use a small belt-mounted weight placement mechanism for calibration, these devices are located at a height difference from the electronic belt scale, necessitating the configuration of a weight lifting device to achieve a complete weight placement cycle. Furthermore, the weights vibrate when they fall onto the electronic belt scale, affecting the accuracy of the weight readings being weighed. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic weight calibration device which can circulate weights and realize buffering placement, thereby reducing calibration difficulty.

[0005] The utility model is realized through the following technical scheme: an automatic weight calibration device, including a conveying assembly arranged above an electronic belt scale, the conveying assembly including a conveyor belt and a roller, the roller is provided with two rollers installed on the inner side of the conveyor belt to drive, and a section of the conveyor belt located below the roller is in a hanging state; a plurality of hooks are evenly arranged and installed on the conveyor belt; a weight body is provided with a handle corresponding to the hook above, and the hook suspends the weight body to move around the conveyor belt.

[0006] Furthermore, it also includes a tensioning wheel, which is arranged on the inner side of the conveyor belt and is in rolling contact with the conveyor belt.

[0007] Furthermore, it also includes a mounting side plate, the tensioning wheel and the roller are mounted on the mounting side plate, and an adjustment slot is opened on the mounting side plate, and one end of the tensioning wheel slides into the adjustment slot.

[0008] Furthermore, the length direction of the adjustment notch remains perpendicular to the conveyor belt.

[0009] Furthermore, a base is provided at one end of the hook, and the base is detachably connected to the conveyor belt via screws.

[0010] Furthermore, the hook is a square structure.

[0011] Furthermore, the handles are provided with at least two groups arranged side by side and spaced apart.

[0012] Furthermore, one end of the roller is connected to a reducer.

[0018] The following is further described in conjunction with specific embodiments. Figure 1-Figure 3As shown, this embodiment is an automatic weight calibration device, including a conveying assembly 2 arranged above an electronic belt scale 1, the conveying assembly 2 including a conveyor belt 21 and a roller 22, the roller 22 is provided with two pieces of conveyor belt 21 installed inside to drive, and a section of the conveyor belt 21 located below the roller 22 is in a hanging state; a plurality of hooks 23 are evenly arranged and installed on the conveyor belt 21; a weight body 3 is provided with a handle 31 corresponding to the hook 23 above it, and the hook 23 suspends the weight body 3 to move around the conveyor belt 21; specifically, by the conveying assembly 2 arranged above the electronic belt scale 1 Part 2 circulates and conveys the weight body 3 to its feed end. When the hook 23 drives the weight body 3 to the lower hanging part of the conveyor belt 21, the weight body 3 gradually moves down and contacts the surface of the electronic belt scale 1, and the connection between the handle 31 and the hook 23 is separated, so that the weight of the weight body 3 acts completely on the electronic belt scale 1, and the conveyor belt 21 moves further, the position of the hook 23 rises and drives it to contact the handle 31, so that the weight body 3 is lifted, realizing the calibration work of the electronic belt scale 1. At the same time, the conveyor belt 21 has a certain buffer placement, and the calibration accuracy is high.

[0019] like Figure 2 As shown, this embodiment also includes a tensioning wheel 4, which is arranged on the inner side of the conveyor belt 21 and is in rolling contact with it; specifically, by arranging the tensioning wheel 4 on the inner side to press down this section of the conveyor belt 21, the conveyor belt 21 at one end above the electronic belt scale 1 is in a V-shaped state, and the weight body 3 has a process of falling, placing the box and lifting it.

[0020] like Figure 1 and Figure 3 As shown, this embodiment also includes a mounting side plate 5, on which the tensioning wheel 4 and the roller 22 are mounted, and an adjustment slot 51 is provided on the mounting side plate 5, into which one end of the tensioning wheel 4 slides; specifically, the tensioning wheel 4 can be moved on the adjustment slot 51 to adjust the tension of the conveyor belt 21.

[0021] It is worth noting that the length direction of the adjustment slot 51 is perpendicular to the conveyor belt 21 , and the conveyor belt 21 and the surface liquid of the electronic belt scale 1 are in a parallel state.

[0022] In order to facilitate disassembly and installation with the conveyor belt 21, a base 231 is provided at one end of the hook 23. The base 231 and the conveyor belt 21 are detachably connected by screws. The screws can be fixedly installed on the surface of the conveyor belt 21. When the base 231 is installed on the conveyor belt 21, the screws will pass through the base 231, and then the nut will be put on to complete the installation of the base 231.

[0023] like Figure 3As shown, the hook 23 is a square structure, which will tilt during the upward movement, so that the hook 23 abuts against the handle 31 and drives the weight body 3 to move along the surface of the conveyor belt 21.

[0024] Optionally, the handles 31 are provided with at least two groups arranged side by side and spaced apart, so that the weight body 3 will not deviate in the suspended state.

[0025] In order to adapt the moving speed of the conveyor belt 21 to be consistent with that of the electronic belt scale 1 , a reducer 6 is connected to one end of the roller 22 , and the moving speed of the conveyor belt 21 is controlled by adjusting the reducer 6 .

[0026] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
