Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of roller scales, in particular to a power roller scale. Background Art
[0002] A roller scale is an industrial electronic scale that installs rollers on the basis of an electronic scale to achieve the functions of automatic conveying and weighing of goods. It is widely used in various occasions that require continuous and efficient weighing, such as production lines, logistics centers, warehouse management, etc.
[0003] Generally, an electronic roller scale uses the friction between the rotating roller and the object to move the object forward. In a power roller assembly line, the method of driving the roller is usually group driving. The motor and the reducer are combined together, and the roller is driven to rotate through chain drive or belt drive. However, when the traditional roller scale is used, it is easy to cause the object to be placed unstably, and it is easy for the object to slide from the edge of the roller.
[0004] Based on this, Chinese Patent CN220322515U discloses a roller scale, which includes a device body. The device body includes a roller scale body. Support components are provided at the four corners of the bottom end of the roller scale body. Blocking components are fixedly installed on both sides of the top end of the roller scale body. The blocking component includes a blocking frame, and the blocking frame is arranged on both sides of the top end of the roller scale body. This kind of roller scale is provided with a blocking component. Adopting this design brings the effect that by rotating the first screw and meshing the thread between the first screw and the second nut sleeve, the distance between the guide plate and the blocking frame can be adjusted, so as to achieve the effect of adjusting the distance between the two blocking frames. During the movement of the blocking frame, the telescopic cloth sleeve expands and contracts to adjust the connection angle. Through the telescopic cloth sleeve and the guide plate, the two sides of the article can be blocked and guided during the process of material conveying and weighing, which can ensure that the material is gathered towards the middle and avoid falling during the process of weighing and conveying.
[0005] However, the above-disclosed roller scale still has technical problems of unsmooth article transmission and inaccurate weighing. Specifically, the roller scale in the prior art mainly places the power machine on the side, and drives a roller located at the outermost side of the frame to rotate through chain drive or belt drive, and then drives each roller to rotate one by one. The output power of this kind of transmission form will gradually attenuate the torque as the roller is far away from the power machine, resulting in difficult rotation of the roller on the other side. A feasible method is to increase the output torque of the power machine as much as possible, which will lead to an increase in material costs. Moreover, the offset power machine structure will also cause the center of gravity of the roller scale to be offset, which is not conducive to the leveling of the weight sensor, resulting in inaccurate measured weight during mobile measurement. Summary of the Utility Model
[0006] Based on this, it is necessary to provide a powered roller scale for the technical problem of how to improve the measurement accuracy of the roller scale.

[0028] Please refer to Figures 1 to 4 , a dynamic roller scale of the present utility model includes: a support frame 1, a plurality of roller structures 2, a power mechanism 3, a transmission module 4, a measurement module 5 and a human-machine interaction module 6; a plurality of the roller structures 2 are uniformly arranged and movably disposed above the support frame 1, the power mechanism 3 is disposed below the middle of the support frame 1, the transmission module 4 is respectively connected to the power mechanism 3 and each of the roller structures 2; the four measurement modules 5 are respectively disposed at the bottom of the four sides of the support frame 1, the human-machine interaction module 6 is disposed adjacent to the support frame 1, and each of the measurement modules 5 is electrically connected to the human-machine interaction module 6.
[0029] Specifically, when a power roller scale of the present utility model is in the working process, after the power mechanism 3 is powered on and started, it can drive each of the rolling structures 2 through the transmission module 4 respectively, so that the roller structure 2 can be driven to rotate on the support frame 1. Since the power mechanism 3 is arranged below the middle of the support frame 1, thus, it can symmetrically transmit power from the middle of the support frame 1 to both sides through the transmission module 4 to reduce the attenuation speed of the power; thereby, the torque required for power output can be reduced with the same structural solution; so as to facilitate the control of the material cost of the roller scale. In addition, a measurement module 5 is correspondingly arranged at the bottom of each corner of the support frame 1, thus, the support frame 1 can be supported and lifted evenly by multiple groups of the measurement modules 5; combined with the form of the central power mechanism 3, a power roller scale of the present utility model can have the advantage that the center of gravity is evenly downward; therefore, it is beneficial to quickly level the weighing zero point of the measurement module 5 to make the measured data accurate; moreover, when an object is driven by the roller structure 2 to pass above the support frame 1, the weighing center of gravity of the object can be flattened, and the measurement speed and accuracy of the measurement module 5 can also be significantly improved. After that, the measured data can be displayed in real time through the human-machine interaction module 6, and the user can also perform operations such as leveling the measurement module 5 and issuing instructions through the human-machine interaction module 6.
[0030] Further, the support frame 1 has a load-bearing frame 101 and support feet 102; a plurality of the roller structures 2 are evenly arranged in the load-bearing frame 101, and the four support feet 102 are respectively arranged at the bottom of the four sides of the load-bearing frame 101, and a measurement module 5 is correspondingly arranged at the bottom of each support foot 102.
[0031] Further, each roller structure 2 is provided with a roller rotating shaft 201, a rotating cylinder 202, a first transmission wheel 203 and a second transmission wheel 204; the roller rotating shaft 201 is connected to the load-bearing frame 101, and the rotating cylinder 202 is connected to the roller rotating shaft 201; the first transmission wheel 203 and the second transmission wheel 204 are adjacently arranged at one end of the roller rotating shaft 201.
[0032] Further, the power mechanism 3 has a suspension bracket 301 and a frequency conversion control motor 302; the suspension bracket 301 is arranged below the middle of the load-bearing frame 101, and the frequency conversion control motor 302 is connected to the suspension bracket 301.
[0033] Further, the transmission module 4 includes a speed reducer 401, a power output shaft 402, a power output wheel 403, a power output transmission belt 404, and a number of alternating transmission belts 405; the speed reducer 401 is power-connected to the variable-frequency control motor 302, and the power output shaft 402 is respectively connected to the speed reducer 401 and the power output wheel 403; the power output transmission belt 404 is respectively connected to the power output wheel 403 and two adjacent first transmission wheels 203 located above the power output wheel 403; each alternating transmission belt 405 is respectively connected to two adjacent first transmission wheels 203 and the second transmission wheel 204.
[0034] Specifically, after the variable-frequency control motor 302 is started, its power is output to the speed reducer 401. After the speed reducer 401 reduces the speed and increases the torque, the power is transmitted to the power output wheel 403. The power output wheel 403 can drive the two first transmission wheels 203 located above it respectively through the power output transmission belt 404. When the two first transmission wheels 203 located above the power output wheel 403 rotate, they can drive their respective corresponding drum rotating shafts 201, so that the corresponding rotating cylinders 202 rotate. Thereafter, each second transmission wheel 204 provided in the drum structure 2 can rotate simultaneously with the first transmission wheel 204, so as to drive a first transmission wheel 203 provided in an adjacent drum structure 2 through the alternating transmission belt 405, and the second transmission wheel 203 provided in the drum structure 2 can continue to drive the next first transmission wheel 203. In this way, in a cycle, starting from the middle of the search and bearing frame 101, each drum structure 2 can be alternately driven starting from the positions on both sides in turn. This transmission form can shorten the attenuation distance of the output power and make the center of gravity of each component on the support frame 1 evenly centered; it is beneficial to improve the detection accuracy of the measurement module 5.
[0035] Further, each of the measurement modules 5 has a measurement pedestal 501, a weight sensor 502, and an adjustment strut 503; the weight sensor 502 is disposed on the measurement pedestal 501, the weight sensor 502 is connected to the bottom of the support leg 102, and the weight sensor 502 is electrically connected to the human-machine interaction module 6; the two adjustment struts 503 are respectively disposed on both sides of the weight sensor 502, and each adjustment strut 503 is respectively connected to the support leg 102 and the measurement pedestal 501. Specifically, the weight sensor 502 can convert the weight it senses into measurement data and transmit it to the human-machine interaction module 6 in real time, and the human-machine interaction module 6 processes the data and then displays it. The adjustment strut 503 is used to actively adjust the distance between the measurement pedestal 501 and the support leg 102, so that it can play a role in adjusting or calibrating the weight sensor 502.

Therefore, the dynamic roller scale of the present utility model solves the technical problem of how to improve the measurement accuracy of the roller scale.
