When put together with the transmission device, it forms a transmission system, which brings a lot of convenience in our lives.

[0003] Although traditional conveyor belts can achieve basic performance, their overall structure is mostly simple and usually only has basic conveying functions. In many cases, conveyor belts often need to weigh the items passing through when in use. In order to reduce the workload of staff, conveyor belts with automatic weighing functions came into being, so that conveyor belts can automatically weigh the weight of objects when conveying objects, thereby improving the practicality of conveyor belts.

However, most conveyor belt weighing platforms are set up between two groups of conveying mechanisms. When the weighing piece moves from one group of conveying mechanisms to the upper end of the conveyor belt weighing platform, the moving direction of some weighing pieces will be offset, so that during the process of the conveyor belt transporting the weighing piece, the weighing piece falls from the upper end of the conveyor belt weighing platform to the ground, causing damage to the weighing piece.

[0061] The working principle of the present invention is as follows: when the staff uses the weighing platform to weigh the weighing object, the staff moves the weighing platform between the two sets of transmission mechanisms, the staff pulls one end of the movable block 44 to move from the inside of a set of reserved grooves 45, and then the staff rotates with the movable column 41 as the center of the circle, thereby driving the control rod 43 to rotate with the movable column 41 as the center of the circle, and then driving the movable column 41 to rotate, and then driving the second movable bevel gear 42 to rotate, and the second movable bevel gear 42 is meshed and connected with a set of limit bevel gears 40, so a set of limit bevel gears The wheel 40 rotates, thereby driving a group of second limiting shafts 39 to rotate, and then driving another group of limiting bevel gears 40 to rotate, and the multiple groups of limiting bevel gears 40 are respectively meshed and connected with the multiple groups of third movable bevel gears 47, so the multiple groups of movable cylinders 46 and the multiple groups of second limiting shafts 39 rotate, and the inner walls of the multiple groups of movable cylinders 46 are respectively threadedly connected with the outer walls of the multiple groups of supporting legs 48, so the multiple groups of supporting legs 48 are displaced, so that the base 38 is displaced upward, thereby driving the mounting frame 1 to move upward, so that the horizontal height of the conveyor belt 14 is the same as the horizontal height of the two groups of transmission mechanisms;

[0062] When the horizontal height of the conveyor belt 14 is the same as that of the two sets of conveying mechanisms, the staff moves one end of the movable block 44 into a set of reserved grooves 45, and the magnets in the reserved grooves 45 match the magnets in the movable block 44, so the movable block 44 is limited and fixed, and then the staff sets the drive motor 9 to start indirectly through the control panel 16;

[0063] When the weighing object falls to the upper end of the conveyor belt 14 through a set of transmission mechanisms, the driving motor 9 is started, driving the driving shaft 10 to rotate, and the driving shaft 10 is connected to a set of conveyor rollers 13 through a synchronous belt, and a set of conveyor rollers 13 rotates, and the two sets of conveyor rollers 13 are connected through the synchronous belt, so the two sets of conveyor rollers 13 rotate synchronously, thereby driving the conveyor belt 14 to operate, and then driving the weighing object to move;

[0064] When the two groups of conveying rollers 13 rotate, one group of conveying rollers 13 is connected to the transmission shaft 19 through a synchronous belt, so the transmission shaft 19 rotates, and the transmission shaft 19 is connected to the two groups of linkage shafts 23 through synchronous belts, so the two groups of linkage shafts 23 rotate, thereby driving the two groups of linkage gears 25 to rotate, and the two groups of linkage gears 25 are respectively meshed and connected with the two groups of first tooth plates 27, so that the elastic sheet 29 is prevented from pushing the connecting rod 26 to move, thereby preventing the second tooth plate 28 from moving;

[0065] The conveyor belt 14 drives the weighing piece to move to one side of a group of movable plates 22, thereby pushing a group of movable plates 22 to be displaced, and then driving multiple groups of telescopic columns 32 to be displaced, and the outer walls of the multiple groups of telescopic columns 32 are respectively threadedly connected with the inner walls of the multiple groups of contraction cylinders 31, so the multiple groups of contraction cylinders 31 rotate, and one group of contraction cylinders 31 is connected with the movable shaft 33 through a synchronous belt, so the movable shaft 33 rotates, thereby driving the first movable bevel gear 34 to rotate, and the first movable bevel gear 34 is meshed and connected with the limiting bevel gear 36, so the limiting bevel gear 36 rotates, thereby driving the limiting cylinder 35 to rotate, and the inner wall of the limiting cylinder 35 is threadedly connected with the outer wall of the limiting column 37, so the limiting column 37 is displaced, so that one group of limiting columns 37 is separated from one group of limiting holes 49, but one end of the other group of limiting columns 37 is not separated from the other group of limiting holes 49, so the limiting fixation of the connection ends of the two groups of guide plates 21 is not released;

[0066] The arrangement of the two groups of guide plates 21 allows the weighing piece to move toward the connection end of the two groups of guide plates 21, so that the weighing piece contacts the other group of movable plates 22, thereby pushing the other group of movable plates 22 to move, and then driving the other group of limit posts 37 to move, so that the other group of limit posts 37 is separated from the other group of limit holes 49, releasing the limit fixation of the connection end of the two groups of guide plates 21, and the conveyor belt 14 drives the weighing piece to move, thereby driving one end of the two groups of guide plates 21 to move;

[0067] When the weighing piece moves to the center end of the weighing platform, the driving motor 9 is turned off, so that the transmission shaft 19 stops rotating, and the two sets of elastic sheets 29 push the two sets of connecting rods 26 to move respectively, thereby driving the two sets of first toothed plates 27 and the two sets of second toothed plates 28 to move, and the two sets of first toothed plates 27 are respectively meshed and connected with the two sets of linkage gears 25, so the two sets of linkage gears 25 rotate, thereby driving one end of the two sets of linkage shafts 23 to rotate. Due to the setting of the two sets of one-way bearings 24, the other ends of the two sets of linkage shafts 23 do not rotate;

[0068] When the two sets of second tooth plates 28 are displaced, the two sets of second tooth plates 28 are respectively meshed and connected with the two sets of limit gears 30, so the two sets of limit gears 30 rotate, thereby driving the two sets of first limit shafts 20 to rotate, and then driving the two sets of guide plates 21 to displace, so that one end of the two sets of guide plates 21 are separated from the outer wall of the weighing piece, avoiding that one end of the two sets of guide plates 21 are connected to the weighing piece, which affects the weighing data of the weighing piece. The multiple sets of weighing sensors 2 measure the weight of the weighing piece, and transmit the data to the control screen 16, and record it through the control screen 16;

[0069] When the weighing piece completes the weighing measurement, the driving motor 9 is started, driving the conveyor belt 14 to operate, and the conveyor belt 14 transports the weighing piece to another set of transmission mechanisms. At the same time, the two sets of linkage shafts 23 rotate, driving the two sets of connecting rods 26 to move, thereby releasing the connection between the two sets of second toothed plates 28 and the two sets of limiting gears 30, and the torsion spring drives the two sets of first limiting shafts 20 to rotate, thereby driving the two sets of guide plates 21 to reset, and the connecting ends of the two sets of guide plates 21 fit together, and the magnets inside the two sets of limiting holes 49 are attracted to the magnets inside the two sets of limiting columns 37 respectively, so that one end of the two sets of limiting columns 37 enters the two sets of limiting holes 49 respectively, thereby driving the two sets of movable plates 22 to reset;

[0070] The present invention is provided with a guide plate 21 and a movable plate 22. The connection ends of the two groups of guide plates 21 are limited and fixed. The conveyor belt 14 drives the weighing piece to move. The two groups of guide plates 21 are provided so that the weighing piece moves toward the connection ends of the two groups of guide plates 21, thereby avoiding the weighing piece from shifting in the moving direction and causing the weighing piece to fall from the conveyor belt 14 to the ground, thereby protecting the weighing piece.
