[0018] 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.

[0019] See also Figure 1-3 ,This embodiment provides a technical solution: a weight detection conveyor belt, comprising a shell 1;

[0020] Shell 1: Conveyor rollers 2 are rotatably connected between the upper ends of the front and rear inner walls thereof through a rotating shaft, and the two conveyor rollers 2 are connected through a transmission belt 3. A motor 4 is provided on the rear side of the shell 1. The end of the output shaft of the motor 4 is fixedly connected to the rotating shaft of the conveyor roller 2 on the left side. The motor 4 is started, and the output shaft of the motor 4 drives the conveyor roller 2 on the left side to rotate. Through the transmission connection of the conveyor belt 3, the two conveyor rollers 2 are synchronously rotated, and the rotation of the conveyor belt 3 is used to transport the objects. The front and rear ends of the shell 1 are vertically slidably connected with support frames 5. A detection column 6 is installed between the upper ends of the support frames 5. The detection column 6 is in contact with the lower surface of the upper end of the conveyor belt 3. Distance measuring sensors 7 are provided on the front and rear ends of the shell 1. When the object moves to the middle of the conveyor belt 3, the object is moved under the action of gravity. Under the action of the pressure sensor 7, the rubber conveyor belt 3 is deformed, and a downward force is applied to the detection column 6 to push the support frame 5 to move downward. The distance the support frame 5 moves downward is detected by the distance measuring sensor 7, and the deformation amplitude of the conveyor belt 3 is judged, and then the weight of the object is determined. A single-chip microcomputer 9 is provided on the front surface of the shell 1. The input end of the single-chip microcomputer 9 is electrically connected to the external power supply to control the start and stop of the entire device. The input end of the motor 4 is electrically connected to the output end of the single-chip microcomputer 9, and the output end of the distance measuring sensor 7 is electrically connected to the input end of the single-chip microcomputer 9. The support frame 5 includes a door-shaped column 51 and a slide plate 52. The door-shaped column 51 is respectively vertically slidably connected to the front and rear ends of the shell 1, and the outer arc surface of the horizontal column of the door-shaped column 51 is respectively horizontally slidably connected with the slide plate 52. The two corresponding longitudinal positions The slide plates 52 are rotatably connected with the detection columns 6 through the second rotating shaft, which provides space for adjusting the spacing between the detection columns 6. During the detection process, the detection column 6 and the conveyor belt 3 rotate relative to each other to reduce the friction force on the conveyor belt 3. The support frame 5 also includes an adjusting screw 53, which is rotatably connected between the left and right ends of the door-shaped column 51. The thread directions of the left and right ends of the adjusting screw 53 are opposite. The adjusting screw 53 is threadedly connected to the screw hole in the middle of the slide plate 52. When the adjusting screw 53 rotates, the two slide plates 52 are driven to move through the threaded connection between the adjusting screw 53 and the slide plate 52. Because the thread directions of the left and right ends of the adjusting screw 53 are opposite, the two slide plates 52 on the same door-shaped column 51 move in opposite directions, which adjusts the spacing between the two detection columns 6. For adjustment, the support frame 5 also includes an adjusting motor 54, which is respectively arranged at the right end of the door-shaped column 51, and the output shaft of the adjusting motor 54 is respectively fixedly connected to the adjacent adjusting screw 53, and the input end of the adjusting motor 54 is electrically connected to the output end of the single-chip microcomputer 9 to provide power for the rotation of the adjusting screw 53. The support frame 5 also includes a spring 55, which is movably sleeved on the outer arc surface of the vertical column of the door-shaped column 51, and the upper end of the spring 55 is fixedly connected to the door-shaped column 51, and the lower end of the spring 55 is fixedly connected to the shell 1 to ensure that the detection column 6 is always in contact with the upper end of the conveyor belt 3. The upper surface of the shell 1 is provided with a door-shaped frame 10, and the middle part of the door-shaped frame 10 is provided with a photoelectric sensor 11, and the output end of the photoelectric sensor 11 is electrically connected to the input end of the single-chip microcomputer 9.The photoelectric sensor 11 is used to detect the conveying position of the item to determine whether the item is conveyed to the top of the weight detection component. The upper end between the front and rear inner walls of the housing 1 is rotatably connected to the support column 8 through the rotating shaft 3. The support column 8 is in contact with the lower surface of the upper end of the conveyor belt 3 to provide support for the upper end of the conveyor belt 3.

[0021] The working principle of a weight detection conveyor belt provided by the utility model is as follows: when in use, an article is placed on the upper surface of the conveyor belt 3, and the motor 4 is started by the single chip microcomputer 9. The output shaft of the motor 4 drives the conveyor roller 2 on the left to rotate, and the two conveyor rollers 2 are synchronously rotated through the transmission connection of the conveyor belt 3, and the rotation of the conveyor belt 3 is used to convey the article. During the conveying process, because the middle part of the conveyor belt 3 adopts elastic support, when the article moves to the middle of the conveyor belt 3, the rubber conveyor belt 3 is deformed under the action of the gravity of the article, and a downward force is applied to the detection column 6, which pushes the door frame 10 to overcome the elastic force of the spring 55 and move downward. The distance sensor 7 detects the downward movement distance of the gate column 51, determines the deformation amplitude of the conveyor belt 3, and further determines the weight of the item. In the process of item weight detection, the adjusting motor 54 is started according to the size of the item. The output shaft of the adjusting motor 54 drives the adjusting screw 53 to rotate. The threaded connection between the adjusting screw 53 and the slide 52 drives the two slides 52 to move. Because the threads at the left and right ends of the adjusting screw 53 are in opposite directions, the two slides 52 on the same gate column 51 move in opposite directions. The spacing between the two detection columns 6 is adjusted to transfer the gravity of the item to the gate column 51 more evenly, thereby improving the accuracy of the detection result.

[0022] It is worth noting that the single-chip microcomputer 9 disclosed in the above embodiment can use a PIC16F1823-I / P model single-chip microcomputer, and the adjustment motor 54, motor 4 and ranging sensor 7 can be freely configured according to the actual application scenario. The adjustment motor 54 and motor 4 can both use 3M57-42A model stepper motors, and the ranging sensor 7 can use a T150HJG-CGQ model reflective laser ranging sensor. The single-chip microcomputer 9 controls the adjustment motor 54, motor 4 and ranging sensor 7 to work using methods commonly used in the prior art.
