Description

Technical Field

[0001] The utility model relates to the technical field of roller scales, in particular to a three-section power roller scale. Background Art

[0002] A roller scale is a weighing device equipped with a roller conveyor belt on an electronic scale, mainly used for transporting goods and weighing them. The working principle of the roller scale is to drive the object to move forward by the friction between the rotating rollers in the roller conveyor belt and the object. In a power roller assembly line, a motor and a reducer can be combined, and the roller is driven to rotate through chain drive or belt drive, so as to achieve the purpose of automatic transportation and weighing of goods.

[0003] At present, roller scales are widely used in various scenarios that require the combination of transportation and weighing, such as industrial control, food processing, commercial pricing and other fields. Especially in industrial production assembly lines, roller scales can be well combined with the assembly lines to achieve fast dynamic weighing or static weighing of goods, saving costs for enterprises and improving productivity.

[0004] Based on this, Chinese Patent CN218663615U discloses a large-piece roller scale, which includes a bottom frame and a partition plate rotatably connected to the upper surface of the bottom frame. A transmission frame is fixed on the partition plate, and a plurality of roller bodies are rotatably connected inside the transmission frame at equal intervals. And a control display for monitoring the weight and moving speed of goods is installed on one side of the transmission frame. The partition plate is rotatably connected to the bottom frame through a load-bearing bearing, and a shaft rod is fixedly connected inside the load-bearing bearing of the partition plate. The bottom of the shaft rod extends below the bottom frame and is provided with a gear. This kind of roller scale realizes the adjustment of the angle of the transmission frame by installing an angle adjustment mechanism between the bottom frame and the partition plate, and then meets the transmission and movement of goods in different directions. At the same time, a discharging mechanism is arranged at the discharging port of the equipment, which can assist in discharging, and solves the problems that the equipment angle cannot be adjusted and cannot assist in discharging at the present stage.

[0005] However, the above-disclosed roller scale still has the technical problem that it cannot reverse the conveyed goods.

[0030] Specifically, when the three-section power roller scale of the present utility model is in the working process, one of the roller conveyor modules 1 is connected to an external production line. After that, the products flowing in from the external production line can be sequentially conveyed and flow over the three roller conveyor modules 1 that are connected end to end in sequence. When the product flows over the surface of one of the roller conveyor modules 1 arranged in the middle, the four weighing and measuring modules 2 arranged at its bottom can sense the weight data of the product and transmit the weight data to the human-computer interaction module 7. Then, the human-computer interaction module 7 displays the measurement result. The user can zero the weighing and measuring module 2 or control the reversing action module 5 through the human-computer interaction module 7, etc. The product that has completed weighing and measurement continues to flow into the next roller conveyor module 1. The reversing action module 5 connected to the roller conveyor module 1 starts and pushes the product onto the reversing roller conveyor 6, and the product is pushed by the reversing roller conveyor 6 to continue flowing into the next working station, such as the packaging station. The pad height adjusting and leveling support frame 4 is used to lift the two-sided roller conveyor modules 1 so that the conveying planes of each group of roller conveyor modules 1 are aligned, making the process of conveying products stable and conducive to accurate measurement of weighing data. It can be seen that the three-section power roller scale of the present utility model solves the technical problem of how to reversely convey the weighed products.

[0031] Furthermore, each roller conveyor module 1 is provided with a roller support frame 101, a motor connection frame 102, a servo motor 103, a power output wheel 104, an output drive chain 105, a roller structure 106, a first drive wheel 107, a second drive wheel 108, and an alternating drive chain 109; the motor connection frame 102 is arranged on one side surface of the roller support frame 101, and the servo motor 103 is connected to the motor connection frame 102; the power output wheel 104 is movably arranged on the side surface of the servo motor 103, the power output wheel 104 is power-connected to the servo motor 103, and one end of the output drive chain 105 is connected to the power output wheel 104; a plurality of the roller structures 106 are evenly arranged and movably arranged on the upper part of the roller support frame 101, and the first drive wheel 107 and the second drive wheel 108 are adjacent and spaced at the same side end of each roller structure 106; the output drive chain 105 is respectively connected to the first drive wheel 107 and the power output wheel 104 arranged on one of the roller structures 106 which is arranged above the servo motor 103 and at the outermost edge side of the roller support frame 101; each alternating drive chain 109 is in transmission connection with the first drive wheel 107 arranged at the end of one roller structure 106 and the second drive wheel 108 arranged at the end of another roller structure 106 adjacent to the roller structure 106.

[0032] Specifically, after the servo motor 103 is powered on and starts, it can drive the power output wheel 104 to rotate, so that power is transmitted through the output transmission chain 105 to the first transmission wheel 107 provided on one of the drum structures 106 disposed above the servo motor 103 and at the outermost edge side of the drum support frame 101, enabling the drum structure 106 to rotate around its connection with the drum support frame 101; then, the power is transmitted from the first transmission wheel 107 through the alternating transmission chain 109 to the second transmission wheel 108 provided on another adjacent drum support frame 101, to drive the drum structure 106 to rotate; and so on, each of the drum structures 106 can be gradually made to rotate; so that the product flowing into the upper part of the drum structure 106 can be driven by the frictional force of the drum and pushed forward by the pusher.

[0033] Further, each weighing measurement module 2 is provided with a weighing support pillar structure 201, a weighing connection block 202, an adjustment connection column 203, and a weight sensor 204; the weighing support pillar structure 201 is connected to the bottom of the drum support frame 101, and the weighing support pillar structure 201 is connected to the top of the weighing connection block 202; the two adjustment connection columns 203 are respectively disposed on both sides of the weighing connection block 202, and each adjustment connection column 203 connects the weighing connection block 202 and the measurement chassis 3; the weight sensor 204 is connected below the weighing connection block 202, the weight sensor 204 is disposed on the measurement chassis 3, and the weight sensor 204 is electrically connected to the human-computer interaction module 7.

[0034] Specifically, the weight of one of the drum conveyor modules 1 disposed above the weighing measurement module 2 can be concentrated among the four weighing support pillar structures 201, and then the weighing support pillar structure 201 transmits the weight through the weighing connection block 202 to the corresponding weight sensor 204, and finally, the weight sensor 204 transmits the measurement signal to the human-computer interaction module 7. In addition, the two adjustment connection columns 203 located on both sides of the weighing connection block 202 can be used to adjust the distance between the weighing connection block 202 and the measurement chassis 3, so that operations such as zeroing the weight sensor 204 can be achieved.

The reversing action arm 505 is connected to the toggle connection frame 504, and extends from the bottom of the plurality of roller structures 106 to the top of the plurality of roller structures 106. Therefore, the reversing action arm 505 can toggle and reverse the product located on one of the roller conveyor belt modules 1 to the reversing roller conveyor belt 6, and the reversing roller conveyor belt 6 changes the transfer direction of the product and then flows into the next station.

[0037] In summary, the three-stage power roller scale of the utility model is respectively provided with a roller conveyor belt module 1, a weighing and measuring module 2, a measuring frame 3, a heightening and leveling support frame 4, a reversing action module 5, a reversing roller conveyor belt 6 and a human-computer interaction module 7; the three roller conveyor belt modules 1 are arranged in sequence, and the bottom of the roller conveyor belt module 1 arranged in the middle is evenly distributed with four weighing and measuring modules 2 around it, and each weighing and measuring module 2 is connected to the top of the measuring frame 3; the two heightening and leveling support frames 4 are respectively arranged on both sides of the measuring frame 3, and the top of each measuring frame 3 is connected to a roller conveyor belt module 1; the reversing action module 5 is respectively connected to a roller conveyor belt module 1 and the reversing roller conveyor belt 6; the human-computer interaction module 7 is arranged adjacent to a roller conveyor belt module 1, and each weighing and measuring module 2 is electrically connected to the human-computer interaction module 7.
