Description

Technical Field

[0001] This utility model relates to the field of weight re-inspection technology, specifically to a weight re-inspection device. Background Technology

[0002] After the bolts are counted and packaged, they will be weighed again to ensure accurate quantity and prevent under- or over-packing or mixing, thus protecting the interests of both the supplier and the buyer. At the same time, it also helps to check the consistency of the products. If the weight deviation of a single package is too large, the bolt specifications and materials can be checked in reverse to see if they meet the requirements.

[0003] For example, Chinese patent CN222491068U discloses an online weighing and re-inspection system. The system uses an electric telescopic rod to bring the clamping plate close to the soybean lecithin packaging bag. A third motor drives a bidirectional lead screw to rotate, clamping the soybean lecithin product through the clamping plate and placing it on the weighing device for weighing. After the weighing and re-inspection is completed, qualified products continue to be conveyed along the production line.

[0004] However, during packaging, there may be issues with proper sealing, which can easily lead to missing bolts. The device can only perform one weighing test on the material, making it difficult to perform a second test to ensure both the quantity of material and the quality of the packaging.

[0005] Based on this, the present invention designs a weight re-inspection device to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a weight re-inspection device.

The feeding conveyor is symmetrically equipped with guide components for adjusting the direction of carton movement. Weighing components for weighing the carton are distributed on the lower right side of the feeding conveyor and the lower side of the unloading conveyor. The vibration leveling mechanism includes a vibration component and a transfer component. The vibration component, which drives the carton and the material inside to vibrate, is located between the feeding conveyor and the unloading conveyor. The transfer component, which transports the carton on the vibration component to the unloading conveyor, is located below the vibration component.

[0008] Furthermore, the guiding assembly includes a mounting base, a fixed frame, an inclined support frame, a parallel support frame, and guide rollers. The mounting base is fixedly mounted on the feeding conveyor, the fixed frame is fixedly mounted on the mounting base, the inclined support frame is fixedly mounted on the fixed frame, the parallel support frame is fixedly mounted on the inclined support frame, and multiple guide rollers are evenly and rotatably mounted at equal intervals on the inclined support frame and the parallel support frame.

The cylinder linear module is fixedly mounted on the support frame, and the electronic scale is fixedly mounted on the moving end of the cylinder linear module. The mounting plate is fixedly mounted on the electronic scale, and support pads are evenly and uniformly fixedly mounted on the mounting plate. The feeding conveyor is a roller conveyor, and the support pads are aligned with the gap between adjacent rollers on the right side of the feeding conveyor.

[0010] Furthermore, the vibration assembly includes a vibration module and a material blocking module, with the material blocking module mounted on the vibration module.

[0011] Furthermore, the vibration module includes a fixed platform, a vibration table, springs, and a vibration motor.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0021] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-2 A weight re-inspection device includes a feeding conveyor 1, a guiding assembly 2, a weighing assembly 3, a vibrating leveling mechanism 4, and a discharging conveyor 5; The feeding conveyor 1, the vibrating and leveling mechanism 4, and the unloading conveyor 5 are distributed from left to right. The feeding conveyor 1 is symmetrically equipped with guide components 2 for adjusting the direction of carton movement. The lower right side of the feeding conveyor 1 and the lower side of the unloading conveyor 5 are equipped with weighing components 3 for weighing the carton. like Figure 2 As shown, the vibration leveling mechanism 4 includes a vibration component 41 and a transfer component 42. The vibration component 41, which is used to drive the carton and the material inside to vibrate, is located between the feeding conveyor 1 and the unloading conveyor 5. The transfer component 42, which is used to transport the carton on the vibration component 41 to the unloading conveyor 5, is located below the vibration component 41.

[0022] In this embodiment, when the weight re-inspection equipment is working normally, the carton is filled with bolts. The carton is moved from left to right by the feeding conveyor 1. The carton is guided by the guide component 2 on the feeding conveyor 1. When the carton moves to the right end of the feeding conveyor 1, the weighing component 3 drives the carton to leave the feeding conveyor 1. The weighing component 3 weighs the carton and its internal bolts. Thus, after the bolts are packaged, the weight of the bolts and the carton is weighed again to determine that the total weight of the internal bolts is consistent with the required weight. Then the weighing component 3 resets, and the feeding conveyor 1 moves the carton to the vibration component 41. The vibration component 41 causes the carton to vibrate, which in turn causes the bolts inside the carton to vibrate, making the bolt area inside the carton flat, which is convenient for subsequent packaging. After the vibration is complete, the transfer component 42 moves the carton away from the vibration component 41 and moves the carton to the unloading conveyor 5. Then the weighing component 3 at the unloading conveyor 5 weighs the carton. If the weights before and after are different, it indicates that the carton may have packaging defects that cause the internal bolts to be exposed.

[0023] Example 2: In some embodiments, as a preferred embodiment of this utility model, such as Figure 4 As shown, the guide assembly 2 includes a mounting base 21, a fixing frame 22, an inclined support frame 23, a parallel support frame 24, and guide rollers 25. The mounting base 21 is fixedly mounted on the feeding conveyor 1. The fixing frame 22 is fixedly mounted on the mounting base 21. The inclined support frame 23 is fixedly mounted on the fixing frame 22. The parallel support frame 24 is fixedly mounted on the inclined support frame 23. Multiple guide rollers 25 are evenly and rotatably mounted at equal intervals on the inclined support frame 23 and the parallel support frame 24. like Figure 5 As shown, the weighing assembly 3 includes a support frame 31, a cylinder linear module 32, an electronic scale 33, a mounting plate 34, and support pads 35. The cylinder linear module 32 is fixedly mounted on the support frame 31. The electronic scale 33 is fixedly mounted on the moving end of the cylinder linear module 32. The mounting plate 34 is fixedly mounted on the electronic scale 33. Support pads 35 are evenly fixedly mounted on the mounting plate 34 at equal intervals. The feeding conveyor 1 is a roller conveyor, and the support pads 35 are aligned with the gap between adjacent rollers on the right side of the feeding conveyor 1.

[0024] like Figures 3-5 As shown, the vibration assembly 41 includes a vibration module and a material blocking module, with the material blocking module mounted on the vibration module; The vibration module includes a fixed platform 411, a vibration table 412, a spring 413, and a vibration motor 414. Multiple guide columns 415 are symmetrically fixedly installed on the fixed platform 411. Springs 413 are sleeved on the guide columns 415. The lower end of the springs 413 is fixedly connected to the fixed platform 411, and the upper end of the springs 413 is fixedly connected to the vibration table 412. The vibration motor 414 is fixedly installed on the lower side of the vibration table 412. The material blocking module includes side baffles 416, which are symmetrically fixedly installed on both sides of the vibrating table 412. The transfer component 42 includes a clearance module and a conveying module, with the conveying module symmetrically installed on the moving end of the clearance module; The yielding module includes a second support frame 421, a second cylinder linear module 422, and a support plate 423. The second cylinder linear module 422 is fixedly installed on the second support frame 421, and the support plate 423 is fixedly installed on the moving end of the second cylinder linear module 422. The conveying module includes an inclined mounting frame 424 and a rotating roller 425. The inclined mounting frame 424 is fixedly mounted on the support plate 423, with the left side of the inclined mounting frame 424 being higher than the right side. The vibration table 412 is symmetrically provided with clearance grooves to facilitate the passage of the inclined mounting frame 424. The rotating rollers 425 are evenly and uniformly mounted on the inclined mounting frame 424. The height of the rotating roller 425 on the left side is higher than the height of the rotating roller 425 on the right side.

[0025] In this embodiment, when the feeding conveyor 1, guiding assembly 2, weighing assembly 3, vibrating leveling mechanism 4 and unloading conveyor 5 are working normally, the carton is filled with bolts. The feeding conveyor 1 drives the carton to move from left to right. The guide rollers 25 on the inclined support frame 23 and parallel support frame 24 guide the carton. When the carton moves to the right end of the feeding conveyor 1, the cylinder linear module 32 drives the electronic scale 33, mounting plate 34 and support pad 35 to move vertically, so that the support pad 35 passes through the gap between the rollers and supports the carton. After the carton is separated from the feeding conveyor 1, the electronic scale 33 weighs the carton and its internal bolts. The linear cylinder module 32 drives the electronic scale 33, mounting plate 34 and support pad 35 to reset. Then, the feeding conveyor 1 moves the carton to the vibrating table 412. The vibration motor 414 is started, and the vibration motor 414 drives the vibrating table 412 to vibrate under the support of the spring 413, thereby causing the carton to vibrate and making the bolt area inside the carton flat, which is convenient for subsequent packaging. After the vibration is completed, the linear cylinder module 422 drives the support plate 423, the inclined mounting frame 424 and the rotating roller 425 to move vertically, so that the inclined mounting frame 424 and the rotating roller 425 pass through the clearance groove and support the carton. Since the left side of the inclined mounting frame 424 is higher than the right side, the rotating roller 425 drives the carton to move to the right under the action of gravity and onto the unloading conveyor 5. The unloading conveyor 5 completes the unloading of the carton.
