[0030] Embodiment 1:

[0031] As Figure 1 shown, this embodiment provides a weight sorter for bottled products. The weight sorter includes a frame 1 and a conveying device, and the conveying device is installed on the frame 1. The conveying device includes a first conveying unit and a second conveying unit.

[0032] The frame 1 is made of stainless steel by sheet metal processing.

[0033] The first conveying unit includes a support column 211 (i.e., the first support element) and a drainage conveying end 2 (i.e., the first conveying end). The bottom of the drainage conveying end 2 is connected to one end of the support column 211, and the other end of the support column 211 is fixedly connected to the frame 1. The second conveying unit includes a second support element and a weighing conveying end 3 (i.e., the second conveying end). The weighing conveying end 3 further includes a weighing sensor 311. The bottom of the weighing conveying end 3 is connected to one end of the second support element, and the other end of the second support element is fixedly connected to the weighing sensor 311. The weighing sensor 311 is placed on the frame 1 and is used to support the weighing conveying end 3 and identify the quality of the bottled product 5. The drainage conveying end 2 has the same structure as the weighing conveying end 3. Both the drainage conveying end 2 and the weighing conveying end 3 are assembled on the frame 1 by bolts, and the drainage conveying end 2 is in the front section of the weighing conveying end 3.

[0034] As Figure 2 shown, taking the weighing conveying end 3 as an example, the conveying end includes a mounting frame 321, a first driving shaft 322, a driven shaft 323, a conveyor belt 324, a motor 325 and a timing belt 326. The motor 325 is fixedly connected to the mounting frame 321. The first driving shaft 322 and the driven shaft 323 are respectively installed at both ends of the mounting frame 321. The conveyor belt 324 is wound around the first driving shaft 322 and the driven shaft 323. The timing belt 326 is wound around the motor 325 and one end of the first driving shaft 322. After the motor 325 is powered on, it drives the timing belt 326 to rotate, and the timing belt 326 drives the first driving shaft 322 to rotate, thereby causing the conveyor belt 324 wound around the first driving shaft 322 and the driven shaft 323 to rotate. Among them, the first driving shaft 322 includes a solid roller shaft and there is a first bearing 3221 at both ends.

[0035] As Figure 3 shown, the driven shaft 323 includes a solid driven roller shaft 3231 and several second bearings 3232. The second bearings 3232 are sleeved on the solid driven roller shaft 3231 at intervals. There is a plastic gasket 3233 between adjacent second bearings 3232. The outer diameter of the plastic gasket 3233 is smaller than the outer diameter of the second bearing 3232, ensuring that the plastic gasket 3233 does not contact the conveyor belt 324 and extending the service life of the conveyor belt. In this embodiment, the conveyor belt 324 is a belt. Driven shaft brackets 3234 are also assembled at both ends of the driven shaft 323.

[0036] As Figure 4 shown, the conveying device further includes a transition plate 4 (i.e., the transition element), which is fixedly connected to the input end of the weighing conveying end 3 through a connecting piece. The output end of the drainage conveying end 2 is docked with the input end of the weighing conveying end 3 and there is a gap. The transition plate 4 is located in this gap, and the upper surfaces of the drainage conveying end 2, the weighing conveying end 3 and the transition plate 4 are flush. The connecting piece can be an element such as a bolt.

[0037] During normal operation, the bottled product 5 enters the diversion conveying end 2 and reaches the docking point between the diversion conveying end 2 and the weighing conveying end 3 through the conveyor belt drive on the diversion conveying end 2. At the docking point, since the diameters of the second driving shaft 212 of the diversion conveying end 2 and the driven shaft 323 of the weighing conveying end 3 are small enough, and a transition plate 4 is installed at the docking point, the formed gap is smaller than the diameter of the bottled product 5, so that the bottled product 5 can smoothly and stably enter the weighing conveying end 3. The weighing sensor 311 weighs and identifies the bottled product 5 by comparing the situation before and after the bottled product 5 enters the weighing conveying end 3.

[0038] In this embodiment, the driving shafts and driven shafts adopted by the diversion conveying end 2 and the weighing conveying end 3 have the same structure. The driving shafts all include solid roller shafts with a diameter of 20 mm and bearings at both ends. The driven shafts all include bearings with an outer diameter of 13 mm, driven roller shafts, and driven shaft brackets assembled at both ends. The bearings are sleeved on the driven roller shafts, and there are plastic gaskets between adjacent bearings. At the docking point between the diversion conveying end 2 and the weighing conveying end 3, a 17-mm gap is formed between the second driving shaft 212 and the driven shaft 323. A transition plate 4 is installed at the gap. Bottled products with a diameter greater than 17 mm can smoothly and stably pass through the gap between the diversion conveying end 2 and the weighing conveying end 3, and then enter the weighing conveying end 3 to weigh and identify the products.

[0039] The aforementioned weight sorter uses driving shafts and driven shafts with small diameters to narrow the gap at the docking of the conveying ends. At the same time, a transition plate 4 is set in the gap, so that bottled products with a diameter greater than 17 mm can also smoothly and stably transition between the two transmission units. At the same time, during normal operation, the motor 325 drives the synchronous belt 326 to rotate, thereby driving the first driving shaft 322 at the other end of the synchronous belt 326 to rotate, making the belt wound around the first driving shaft 322 and the driven shaft 324 rotate, and the outer surface of the bearing of the other driven shaft 323 contacts the belt. The bottled product 5 in the vertical state enters the diversion conveying end 2. The speed of the bottled product 5 is adjusted to be the same as that of the weighing conveying end 3, and then it smoothly enters the weighing conveying end 3 to weigh and identify the product, avoiding the impact caused by inertia when entering the weighing conveying end 3 and improving the weighing accuracy.

[0040] Embodiment 2

[0041] As Figure 5As shown in the figure, this embodiment provides another conveying device for bottled products, which can be used in the weight sorter in Embodiment 1. The difference between the two is that in the conveying device provided in this embodiment, a straight slot 411 is opened on the transition plate 4, and the transition plate 4 is connected to the input end of the weighing and conveying end 3 through the straight slot 411 and a connecting member. By adjusting the position of the connecting member within the range restricted by the straight slot, the position of the transition plate 4 in the gap can be adjusted, thereby adapting to gaps of different specifications and improving the flexibility and adaptability of the conveying device. The rest of the structure is basically the same as that in Embodiment 1 and will not be described in detail here.

[0042] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
