Description

Technical Field

[0001] This utility model relates to the field of express delivery weighing technology, specifically to a dynamic weighing mechanism for express delivery. Background Technology

[0002] In the express delivery and logistics industry, package weighing is a core component of cost calculation and sorting scheduling, and its efficiency and accuracy directly impact the operational efficiency of the entire logistics chain. With the rapid development of the e-commerce industry and the surge in express delivery orders, traditional weighing methods can no longer meet the demands for efficient processing.

[0003] Currently, most express delivery weighing relies on manual operation: after the package is packed, staff need to manually move it onto a platform scale or weighbridge, wait for the weight data to stabilize and record it, and then move it onto the conveyor belt to continue the flow. This method is extremely labor-intensive, with a single operator having to bend over and move packages multiple times a day, which can easily lead to occupational injuries such as lumbar muscle strain; moreover, it is inefficient, with a long time to weigh a single package, and during peak periods, congestion at the weighing stage often leads to a decrease in overall processing efficiency. Utility Model Content

[0004] In view of the problems existing in the dynamic weighing mechanism for express delivery, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a dynamic weighing mechanism for express delivery, which solves the problem that existing express weighing mechanisms usually require staff to manually place the packaged items on the scale for weight measurement, which is very physically demanding for staff and reduces the efficiency of express weighing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A dynamic weighing mechanism for express delivery includes a base.

A T-shaped groove is formed at one end of the push block, and the push block is slidably engaged with the inside of the limiting groove through the T-shaped groove. The push block is fixedly connected to one end of the push rod.

[0008] Preferably, the driving mechanism includes a T-shaped slider, an L-shaped plate, and a motor. The upper surface of the base is provided with a T-shaped groove. The T-shaped slider is slidably disposed inside the T-shaped groove. The L-shaped plate is fixedly connected to the upper surface of the T-shaped slider, and the motor is fixedly connected to the upper surface of the L-shaped plate.

[0009] Preferably, the upper surface of the eccentric wheel is provided with a plurality of mounting holes, and the eccentric wheel is fixedly connected to the output end of the motor through the mounting holes.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model discloses a dynamic weighing mechanism for express delivery.

[0020] This utility model provides, for example Figure 1-3 The dynamic weighing mechanism for express delivery shown includes a base 1. A first U-shaped plate 2 is fixedly connected to the upper surface of the base 1. A second U-shaped plate 3 is fixedly connected to the upper surface of the base 1 inside the first U-shaped plate 2. A U-shaped channel is provided between the first U-shaped plate 2 and the second U-shaped plate 3. Two mounting slots are symmetrically opened inside the U-shaped channel on the upper surface of the base 1. A conveyor belt 4 is installed inside each of the two mounting slots. A circular groove is opened in the middle of the U-shaped channel on the upper surface of the base 1. A weight sensor 5 is fixedly connected inside the circular groove. A groove is opened on one side of the first U-shaped plate 2. A through hole is opened on one side of the groove. A push rod 6 is slidably installed inside the through hole. A push plate 7 is fixedly connected to one end of the push rod 6. A pushing mechanism is provided at one end of the push rod 6. The push rod 6 moves through the pushing mechanism. A driving mechanism is provided on the upper surface of the base 1. The pushing mechanism matches the driving mechanism. The conveying directions of the two conveyor belts 4 are opposite.

[0021] The first U-shaped plate 2 and the second U-shaped plate 3 on the base 1 form a U-shaped channel, providing a directional transport path for express packages. Two conveyor belts 4 are symmetrically arranged in the channel, with opposite transport directions, and are responsible for transporting express packages: initially, the express package is sent into the U-shaped channel by one of the conveyor belts, gradually moves towards the weighing area in the middle of the channel, and then is pushed by the pushing mechanism to push the upper surface of the weight sensor 5.

[0022] In order for the packages to be pushed one by one onto the top surface of the weight sensor, such as Figure 1-3As shown, the pushing mechanism includes a push block 8 and an eccentric wheel 9. The eccentric wheel 9 is disposed on the upper surface of the base 1. A limiting groove is formed around the upper surface of the eccentric wheel 9. A T-shaped groove is formed at one end of the push block 8. The push block 8 is slidably engaged with the inside of the limiting groove through the T-shaped groove. The push block 8 is fixedly connected to one end of the push rod 6. The driving mechanism includes a T-shaped slider 10, an L-shaped plate 11 and a motor 12. A T-shaped sliding groove is formed on the upper surface of the base 1. The T-shaped slider 10 is slidably disposed inside the T-shaped sliding groove. The L-shaped plate 11 is fixedly connected to the upper surface of the T-shaped slider 10. The motor 12 is fixedly connected to the upper surface of the L-shaped plate 11.

[0023] The motor 12 of the drive mechanism drives the eccentric wheel 9 to rotate. The limiting groove on the eccentric wheel slides and engages with the T-shaped groove of the push block 8, converting the circular motion of the eccentric wheel into the reciprocating linear motion of the push block. This, in turn, drives the push rod 6 and the push plate 7 to slide within the through hole of the first U-shaped plate. The push plate 7 pushes the express package to adjust its position, ensuring that it is completely placed above the weight sensor 5. The weight sensor detects and records the weight of the express package in real time.

[0024] In order for the device to push express packages of different sizes onto the upper surface of the weight sensor, such as Figure 1-2 As shown, the upper surface of the eccentric wheel 9 is provided with multiple mounting holes. The eccentric wheel 9 is fixedly connected to the output end of the motor 12 through the mounting holes. Both ends of the T-shaped slider 10 are provided with bolts 13. The T-shaped slider 10 is fixedly connected to the inside of the T-shaped groove by two bolts 13.

[0025] The motor 12 is fixed on the L-shaped plate 11. The L-shaped plate slides in the T-shaped groove of the base 1 through the T-shaped slider 10. The position of the motor and the eccentric wheel can be adjusted according to the size of the express package. After the adjustment is completed, the T-shaped slider is fixed by the bolt 13 to ensure the precise movement of the pushing mechanism.

[0026] To stabilize the device, such as Figure 1 As shown, multiple support seats 14 are fixedly connected to the lower surface of the base 1.

[0027] Multiple support bases 14 on the lower surface of the base 1 enhance the overall structural stability and prevent vibration from affecting the detection accuracy during transmission and weighing.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
