For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0026] In one embodiment of this utility model, such as Figures 1-2 As shown, the provided online weighing machine includes a weighing section 1 and a rejection section 2. The feed end of the rejection section 2 is connected to the discharge end of the weighing section 1. The weighing section 1 has a weighing module 11 for monitoring the weight of the material. The rejection section 2 is provided with a push plate 21 that acts on the material. When the weight of the monitored material meets the standard, the material with the standard weight is sent out from the discharge end of the rejection section 2. When the weight of the monitored material does not meet the standard, the push plate 21 can push the material with the substandard weight out from the side of the rejection section 2. Specifically, the feeding end of weighing section 1 is connected to the incoming material production line. Several materials to be tested are fed into weighing section 1 one by one from the production line. The discharge end of rejection section 2 is connected to the conveying device of the next processing area. The weighing module 11 of weighing section 1 monitors the passing materials in real time. When the weight of the passing materials meets the standard, the materials that meet the weight standard are sent out from the discharge end of rejection section 2 to the conveying device of the next processing area. Otherwise, the push plate 21 on rejection section 2 is used to push the materials, and the materials that do not meet the weight standard are pushed out from the side of rejection section 2 to prevent defective materials from flowing into the next processing area.

[0027] In one embodiment of this utility model, such as Figures 1-2As shown, it also includes a processor and a signal converter. The rejection section 2 is provided with a first drive 22 that is connected to the push plate 21. The weighing module 11 and the processor are respectively electrically connected to the signal converter. The first drive 22 is electrically connected to the power supply through the processor and can drive the push plate 21 to move back and forth in the width direction of the rejection section 2. Specifically, when weighing section 1 carries material, weighing module 11 transmits the mass signal of the material to signal converter. Signal converter converts the mass signal into an electrical signal and outputs it to driver. Driver can preset a standard weighing value. When the weight of the material reaches the preset value, the material continues to be conveyed along the length of rejection section 2, thereby achieving continuity in the production process. When the weight of the material does not reach (exceeds or falls below) the preset value, the material first enters rejection section 2 until it reaches the position corresponding to push plate 21. Driver transmits a working signal to first drive 22, driving push plate 21 to act on the material along the width of rejection section 2 and reset, thereby achieving rejection of defective products. Furthermore, rejection section 2 has an infrared emitter and an infrared reflector arranged opposite to each other and electrically connected to the processor at the end of push plate 21 away from weighing section 1. When the material does not meet the standard and blocks infrared light, driver transmits a working signal to first drive 22.

[0028] In one embodiment of this utility model, such as Figures 1-2 As shown, the rejection section 2 includes a first support 23 and a plurality of first rollers 24 spaced apart along the length of the first support 23. The first drive 22 includes a rodless cylinder and a solenoid valve located at the bottom of the first support 23. The rodless cylinder has a slider 221 capable of reciprocating along the width of the first support 23. The top of the slider 221 is provided with a vertical rod 25. The other end of the vertical rod 25 passes through the gap between adjacent first rollers 24 and its end is connected to the push plate 21. The rodless cylinder is connected to an external air source through the solenoid valve, and the solenoid valve is electrically connected to an external power source through the processor. By using a plurality of spaced first rollers 24, the contact area of ​​the material with the ground in the rejection section 2 is reduced, thereby reducing friction and facilitating the push plate 21 to push out the material. The rodless cylinder also reduces the space occupied by the rejection section 2 in the width direction.

[0029] In one embodiment of this utility model, such as Figures 1-2 As shown, the bottom of the first bracket 23 is provided with a pair of mounting seats, and the two end caps of the rodless cylinder are fixedly connected to the mounting seats. Specifically, the mounting seats are U-shaped, with the two vertical sections connected to the first bracket 23 by screws, and the end caps of the rodless cylinder connected to the horizontal section of the mounting seats by screws.

[0030] In one embodiment of this utility model, such as Figures 1-2As shown, the top of the slider 221 is provided with a connecting seat, and there is a pair of uprights 25. The bottom ends of the pair of uprights 25 are respectively connected to the slider 221 through the connecting seat, and the top ends are respectively connected to the push plate 21. Specifically, the connecting seat is U-shaped. The vertical section of the connecting seat is connected to the top of the slider 221 by screws, and the horizontal section of the connecting seat has a rectangular insertion hole. The uprights 25 are rectangular columns that fit into the rectangular insertion hole. The push plate 21 has a hollow structure with a cavity for the uprights 25 to pass through. After the top end of the three-dimensional structure passes through the cavity, the end end is connected to the top wall of the cavity by screws, thereby reducing the thickness of the push plate 21 and the uprights 25 in the width direction and reducing the interference between the material and the push plate 21 during the conveying process.

[0031] In one embodiment of this utility model, such as Figures 1-2 As shown, it also includes a second drive mounted on the first support 23. The output end of the second drive is provided with a first sprocket, and the ends of several first rollers 24 are respectively provided with second sprockets. The first sprockets are connected to the several second sprockets via chains. Specifically, the second drive is a motor, which drives the first rollers 24 to rotate via chains, thereby moving the material forward.

[0032] In one embodiment of this utility model, such as Figures 1-2 As shown, it also includes a guide plate 26, which is inclinedly disposed on the side of the first bracket 23. The top end of the guide plate 26 is fixedly connected to the first bracket 23, and the bottom end abuts against the bearing surface. Specifically, the top end of the guide plate 26 is fixedly connected to the first bracket 23 by screws, and the bearing surface abutting the bottom end refers to the ground used to place the first bracket 23, thereby providing guidance for the rejected material and facilitating subsequent collection.

[0033] In one embodiment of this utility model, such as Figures 1-2 As shown, it also includes a guide roller. The surface of the guide plate 26 is recessed inward with a strip-shaped groove. The guide roller is embedded in the strip-shaped groove, and its end is rotatably engaged with the end arm of the strip-shaped groove. This facilitates the falling of rejected material along the guide plate 26.

[0034] In one embodiment of this utility model, such as Figures 1-2As shown, the weighing section 1 includes a second support 12, a hollow frame 13 mounted on top of the second support 12, a conveyor belt 14 mounted on the hollow frame 13, and a motor for driving the conveyor belt 14. The weighing module 11 includes a lower support plate, a weighing sensor, and an upper support plate. The weighing sensor is located between the upper support plate and the lower support plate. The bottom end of the lower support plate is fixedly connected to the second support 12. Vertical plates are respectively provided on both sides of the hollow frame 13, and a connecting crossbar 15 is provided between a pair of vertical plates. The connecting crossbar 15 is fixedly connected to the top of the upper support plate. The connecting crossbar 15 connects the pair of vertical plates of the hollow frame 13, improving the stability of the conveyor belt 14 installation.

[0035] In one embodiment of this utility model, such as Figures 1-2 As shown, it also includes an electrical cabinet 3. The processor and the signal converter are respectively located inside the electrical cabinet 3. A three-color warning light 31 is provided on the outer side of the electrical cabinet 3. The three-color warning light 31 is electrically connected to the power supply through the processor. When the weight of the material is below the standard, the processor transmits a working signal to the three-color warning light 31, and the three-color warning light 31 lights up, thus achieving the effect of real-time detection and feedback.
