[0016] This utility model's weighing device includes a feeding conveyor belt, a weighing mechanism, a discharging conveyor belt, a receiving mechanism, and an automatic collection mechanism. When weighing a whole case of products, the feeding conveyor belt transports each product to the weighing mechanism. After weighing, cases with acceptable weights are automatically output via the discharging conveyor belt and proceed to the next process. Cases with unacceptable weights stop when the weight is incorrect. The feeding and weighing conveyors stop, and a geared motor drives a worm gear to rotate, which in turn rotates the weighing conveyor belt by a preset angle until it engages with the receiving mechanism. The weighing conveyor belt then resumes operation, transporting the case to the receiving mechanism.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0030] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.
[0031] Please refer to Figures 1-4 An embodiment of this utility model provides an automatic feeding full-box weighing device, comprising:
[0032] Feeding conveyor belt 1;
[0033] Weighing mechanism 2 is located at the output end of the feeding conveyor belt 1 and includes a base 21. A first bracket 23 is rotatably mounted on the top of the base 21 via a bearing seat 22. A weighing conveyor belt 24 is mounted on the top of the first bracket 23. An electronic belt scale is installed inside the weighing conveyor belt 24. A worm gear 25 is fixedly sleeved on the bottom end of the first bracket 23. A worm 26 is meshed with one side of the worm gear 25. A reduction motor 27 that drives the worm 26 to rotate is fixedly mounted on the base 21.
[0034] The unloading conveyor 3 is located on the side of the weighing mechanism 2 away from the loading conveyor belt 1, and is in a straight line with the loading conveyor belt 1;
[0035] The receiving mechanism 4 is located on one side of the weighing conveyor belt 24 and is connected to the weighing conveyor belt 24 after it has been rotated by a preset angle. It is used to receive the whole box of products that fail to meet the weight requirements.
[0036] Automatic storage mechanism 5 is located on one side of receiving mechanism 4 and is used to automatically store each box of products that fail to meet the weight requirements.
[0037] The controller is electrically connected to the feeding conveyor belt 1, the weighing mechanism 2, the unloading conveyor belt 3, and the automatic storage mechanism 5, respectively.
[0038] In this embodiment, during the weighing and testing of entire cases of products, each case is transported one by one on the loading conveyor belt 1, which then transports the cases to the weighing mechanism 2 for weighing. After weighing, cases that meet the weight requirements are directly transported to the unloading conveyor belt 3 for automatic output and proceed to the next process. Since the number of unqualified cases is small, the unloading conveyor belt 3 and the loading conveyor belt 1 are arranged in a straight line, allowing qualified products to be directly transported without the weighing conveyor belt 24 needing to turn, ensuring smooth operation and improving weighing efficiency.
[0039] When the weight of a whole box of products is unacceptable, the feeding conveyor belt 1 and the weighing conveyor belt 24 stop. The geared motor 27 drives the worm gear 26 to rotate, which in turn drives the weighing conveyor belt 24 to rotate at a preset angle via the worm wheel 25, and then docks with the receiving mechanism 4. At this time, the weighing conveyor belt 24 starts to transfer the whole box of products to the receiving mechanism 4. Then, the automatic collection mechanism 5 automatically collects the unacceptable whole box of products, waiting for further processing. Finally, the weighing conveyor belt 24 resets and continues to weigh.
[0040] The weighing device of this application operates smoothly, realizing automatic weighing of whole boxes of products and automatic screening of unqualified whole boxes of products, thereby improving work efficiency and product weighing accuracy.
[0041] In a preferred embodiment, such as Figure 1 and Figure 3 As shown, the top two sides of the feeding conveyor belt 1 are respectively provided with first baffles 11; the top two sides of the weighing conveyor belt 24 are respectively provided with second baffles 28; the top two sides of the unloading conveyor belt 3 are respectively provided with third baffles 31, to prevent the whole box of products from falling off the sides of the conveyor belt during the transmission process.
[0042] In a preferred embodiment, such as Figure 2 and Figure 3 As shown, the receiving mechanism 4 includes a second support 41. Several first rollers 42 with gradually decreasing height are rotatably arranged on the second support 41 in the direction away from the weighing conveyor belt 24. A temporary storage platform 43 is provided at one end of the second support 41 away from the weighing conveyor belt 24. A fourth baffle 44 is fixedly provided on the top surface of the temporary storage platform 43 away from the second support 41. A buffer pad 45 is fixedly provided on the plate surface of the fourth baffle 44 near the second support 41.
[0043] In this embodiment, when the weight of the entire box of products fails to meet the standard, the weighing conveyor belt 24 rotates at a preset angle and docks with the receiving mechanism 4. The weighing conveyor belt 24 then transports the entire box of products to the first roller 42. The entire box of products slides down the first roller 42 to the temporary storage platform 43 and stops upon hitting the fourth baffle 44. The buffer pad 45 on the fourth baffle 44 provides cushioning protection for the entire box of products. The buffer pad 45 can be made of soft rubber or sponge, providing good cushioning effect.
[0044] In a preferred embodiment, such as Figure 2 and Figure 3 As shown, a first guide channel 46 is fixedly installed on the second bracket 41 above several first rollers 42 to ensure that the whole box of products falls accurately onto the temporary storage platform 43.
[0045] In a preferred embodiment, such as Figure 2 and Figure 3As shown, the automatic storage mechanism 5 includes a storage rack 51. A guide baffle 52 is fixedly installed on the top surface of the temporary storage platform 43 on one side of the output end of the first guide channel 46. A second guide channel 53 is formed between the guide baffle 52 and the fourth baffle 44. A support plate 54 is fixedly installed on the top surface of the temporary storage platform 43 on the other side of the output end of the first guide channel 46. A push cylinder 55 is fixedly installed on the support plate 54. The piston rod of the push cylinder 55 extends toward the second guide channel 53 and is fixedly connected to a push plate 56. The storage rack 51 is fixedly installed at the end of the second guide channel 53 away from the push cylinder 55. A storage channel 57 is fixedly installed on the storage rack 51. Several second rollers 58 with gradually decreasing height are rotatably installed at the bottom of the storage channel 57 in a direction away from the second guide channel 53. A feed port is opened at one end of the storage channel 57 corresponding to the second guide channel 53.
[0046] In this embodiment, after weighing, the unqualified boxes of products fall onto the temporary storage platform 43. The pusher cylinder 55 pushes them into the second guide channel 53 via the pusher plate 56, and then pushes them into the storage channel 57 through the feed port along the second guide channel 53. Each unqualified box of products slides along the second roller 58 to the bottom of the storage channel 57 and is stored one by one for easy processing by staff.
