[0002] A roller scale is a weighing device that uses rollers as weighing units. It adopts high-precision sensors and advanced microprocessor technology, and can provide high-precision, high-stability and high-sensitivity weighing effects. The roller scale usually consists of multiple rollers, and each roller serves as a weighing unit, and multiple items can be weighed simultaneously. The roller scale has the characteristics of high precision, high stability and easy maintenance, and is widely used in various occasions where accurate weighing of materials is required, such as logistics, warehousing, production, etc.

[0003] In the prior art, after the goods are conveyed to the roller scale through the roller conveyor belt for weighing, they are then conveyed to the end by the roller conveyor belt. After the goods are taken off the roller conveyor belt by the palletizing robot, they are palletized to facilitate subsequent boxing of the weighed goods. However, in the actual use process of the existing roller scale, due to the different heights of the conveying lines of different goods and the fixed height of the roller scale which is not easy to adjust, the roller scale cannot be used on conveying lines of different heights to quickly weigh the goods, thus reducing the flexibility of use of the roller scale, and further failing to achieve the purpose of quickly weighing different goods before boxing on conveying lines of different heights.

[0018] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0019] As Figure 1 - Figure 3 shown, a quick weighing device before boxing includes a roller conveyor belt 1 and a palletizing robot 2. A roller scale 3 is arranged between the roller conveyor belts 1. An adjusting mechanism 4 is arranged on the bottom surface of the roller scale 3. The adjusting mechanism 4 includes a frame 5, a support cylinder 8, an adjusting cylinder 11, a partition board 13, a first bevel gear 15, a screw 18 and a second bevel gear 20. The roller scale 3 is movably connected to the top surface of the frame 5 through guide rods 7 at four corner end parts of the bottom surface. The support cylinder 8 is fixedly connected to the inner bottom surface of the frame 5. The adjusting cylinder 11 is fixedly connected to the bottom surface of the roller scale 3 and sleeved outside the support cylinder 8. A partition board 13 is fixedly connected to the inside of the adjusting cylinder 11. The first bevel gear 15 is movably connected inside the adjusting cylinder 11 through a first rotating rod 16 on the right side wall and is located above the partition board 13. The screw 18 is movably connected to the bottom surface of the partition board 13 through a second rotating rod 19 at the top end and is movably connected to a nut 10 in a through hole 9 on the top surface of the support cylinder 8. The second bevel gear 20 is fixedly connected to the top end of the second rotating rod 19 and meshes with the first bevel gear 15.

[0020] As Figure 1 - Figure 3As shown, in this embodiment, in order to enable the roller scale 3 to adjust its own height according to the height of the roller conveyor belt 1 on different conveyor lines through the adjustment mechanism 4, so as to achieve the purpose of quickly weighing the goods on different conveyor lines before boxing, guide holes 6 are respectively opened at the four corner ends of the top surface of the frame 5, guide rods 7 are respectively fixedly installed at the four corner ends of the bottom surface of the roller scale 3, and the guide rods 7 are inserted and installed in the guide holes 6. The support cylinder 8 is fixedly installed on the inner bottom surface of the frame 5, and a through hole 9 is opened on the top surface of the support cylinder 8. A nut 10 is fixedly installed in the top hole of the through hole 9. The adjustment cylinder 11 is sleeved outside the support cylinder 8 and fixedly installed on the bottom surface of the roller scale 3. A first rotation hole 12 is opened above the right side wall of the adjustment cylinder 11. A partition plate 13 is also fixedly installed above the inside of the adjustment cylinder 11, and a second rotation hole 14 is opened on the top surface of the partition plate 13. A first rotation rod 16 is fixedly installed on the right side wall of the first bevel gear 15, and the first rotation rod 16 is movably installed in the first rotation hole 12. A knob 17 is fixedly installed on the outer end wall of the first rotation rod 16. The screw 18 is threadedly connected with the nut 10, and a second rotation rod 19 is fixedly installed at the top end of the screw 18. The second rotation rod 19 is movably installed in the second rotation hole 14, and a second bevel gear 20 is fixedly installed at the top end of the second rotation rod 19. The second bevel gear 20 is meshed with the first bevel gear 15;

[0021] The specific working principle of the adjustment mechanism 4 in cooperation with the roller scale 3 is as follows:

[0022] The weighing principle of the roller scale 3 is to sense the gravity of the goods through sensors, convert the gravity into an electrical signal, and after signal processing and conversion, finally display the weighing result on the display screen. Since the heights of the roller conveyors 1 on different goods conveyor lines are different, the roller scale 3 is installed between the roller conveyors 1. To enable the goods on the roller conveyor 1 to be transported to the roller scale 3 for weighing, the height of the roller scale 3 needs to be adjusted so that the roller scale 3 and the roller conveyor 1 are at the same horizontal position. When adjusting the roller scale 3, rotate the knob 17 located above the right side of the adjusting cylinder 11. The knob 17 will drive the first rotating rod 16 installed on the right side wall of the first bevel gear 15 to rotate in the first rotating hole 12 opened above the right side wall of the adjusting cylinder 11, and the first rotating rod 16 will drive the first bevel gear 15 to rotate inside the adjusting cylinder 11. During the rotation of the first bevel gear 15, because it meshes with the second bevel gear 20, the first bevel gear 15 will drive the second bevel gear 20 to rotate under the meshing action. The second rotating rod 19 installed on the bottom surface of the second bevel gear 20 will rotate in the second rotating hole 14 opened on the top surface of the partition plate 13 installed above the inside of the adjusting cylinder 11, and the second rotating rod 19 will drive the screw rod 18 to rotate. Since the screw rod 18 is threadedly connected to the nut 10 fixedly installed in the orifice of the through hole 9 opened on the top surface of the support cylinder 8 installed on the inner bottom surface of the machine frame 5, the screw rod 18 will drive the adjusting cylinder 11 to move upward outside the support cylinder 8 during rotation, and will lift the roller scale 3 upward during the movement. When the roller scale 3 moves upward, the guide rods 7 installed at the four corner ends of its bottom surface will synchronously move upward in the guide holes 6 opened at the four corner ends of the top surface of the machine frame 5 until the roller scale 3 and the roller conveyor 1 on the conveyor line where the goods need to be weighed are at the same horizontal position. Thus, when the roller conveyor 1 transports the goods and the goods are transported to the roller scale 3, the roller scale 3 can quickly weigh the goods. After weighing, the goods will continue to be transported by the roller conveyor 1 to the position of the palletizing robot 2 at the end. Finally, the palletizing robot 2 will pick up the weighed goods on the roller conveyor 1 and palletize them to facilitate subsequent boxing of the goods. Therefore, the roller scale 3 can quickly adjust its own height according to the heights of the roller conveyors 1 on different conveyor lines, so as to achieve the purpose of quickly weighing the goods on different height conveyor lines before boxing. This not only improves the flexibility of use of the roller scale 3 but also meets the actual use requirements.

[0023] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made thereto without departing from the scope of the present utility model, and components thereof can be replaced with equivalents, or some of the technical features can be equivalently replaced. All such modifications and replacements should be included within the protection scope of the present utility model as long as they are within the spirit and principle of the present utility model.
