DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Embodiment 1: This embodiment is intended to solve the problem that in the prior art, when weighing objects with smaller particle sizes or lighter objects, most of them are placed in a box 110, and then the weight is weighed, and then the volume is calculated. If the weight is lighter, the weighing will be inaccurate. Please refer to Figure 1-Figure 9 A volume weighing device includes a box body 110 and a weighing device 170. A mounting groove 160 is opened in the middle of the box body 110, a fixing plate 150 is fixedly installed at the bottom of the mounting groove 160, the weighing device 170 is fixedly installed in the middle of the fixing plate 150, a measuring plate 200 is electrically connected to the side of the weighing device 170, a pulley 350 is installed on the side of the measuring plate 200, a supporting frame 220 is fixedly installed inside the box body 110, a slide groove 260 is opened in the supporting frame 220, and a damping tube 270 is installed in the middle of the slide groove 260.
[0028] A motor 190 is fixedly installed at the bottom of the fixed plate 150, a fixing slot 180 is opened below the fixed plate 150, the motor 190 is installed in the middle of the fixing slot 180, a measuring slot 410 is opened on the side of the fixing slot 180, a rotating shaft 380 is fixedly installed on the side of the measuring slot 410, a torsion spring 390 is hinged on the side of the rotating shaft 380, a first limit plate 230 is fixedly connected to the side of the torsion spring 390, the installation slot 160 is connected to the measuring slot 410 through the discharge port 250, the torsion spring 390 and the rotating shaft 380 are symmetrically arranged with the discharge port 250, and a second limit plate 240 is fixedly connected to the bottom of the first limit plate 230 through the torsion spring 390.
[0029] When items need to be weighed, the staff will drop the items through the feed plate 130, and then the items will flow into the measuring trough 410 through the feed pipe 400. When a large number of items flow in, the measuring plate 200 will be pushed to move. Through the setting of the damping tube 270, the moving speed of the measuring plate 200 will be controlled, so that during the movement of the measuring plate 200, the pulley 350 will squeeze the damping tube 270, thereby controlling the speed. When no material is fed, due to the setting of the partition 280 in the middle of the damping tube 270, the pulley 350 will stop, thereby greatly improving the accuracy of the weighing device 170 when reading the measurement data.
[0030] When the measuring plate 200 passes through the first limit plate 230 and the second limit plate 240 during movement, due to the setting of the torsion spring 390 and the rotating shaft 380, the measuring plate 200 will squeeze the first limit plate 230 and the second limit plate 240 when being pushed. After the measuring plate 200 passes, due to the torque of the torsion spring 390, the first limit plate 230 and the second limit plate 240 will be reset, and it will not affect the use.
[0031] In the present embodiment, when weighing items, the items are first put into the weighing slot through the feed plate 130, and then when there are a lot of items, the measuring plate 200 will be pushed to make the measuring plate 200 move upward. By setting the damping tube 270, when the measuring plate 200 moves, its movement speed is controlled as much as possible to avoid inaccurate reading during the weighing process of the weighing device 170. This solves the problem that in the prior art mentioned in the above background technology, when weighing items with smaller particle sizes or lighter items, most of them use the box 110 to hold them, and then weigh their weight and then calculate their volume. If the weight is light, the weighing will be inaccurate, thereby greatly improving the accuracy of weighing items.
