[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0029] It should be understood that the specific embodiments described herein are only a part of the embodiments of the utility model and are not intended to limit the utility model. All other embodiments derived from the embodiments of the utility model without creative design are within the scope of protection of the utility model.

[0030] Please refer to Figures 1 to 8 The utility model proposes a weighing bucket device. The preferred embodiment of the weighing bucket device of the utility model includes a weighing bucket 1, a weighing bucket gap connecting rod 2, a weighing bucket turning and unloading mechanism 3 and a weighing bucket lifting mechanism 4.

[0031] Among them, one end of the weighing bucket turning and unloading mechanism 3 is connected to the output end of the weighing bucket lifting mechanism 4, one end of the weighing bucket gap connecting rod 2 is connected to the other end of the weighing bucket turning and unloading mechanism 3, the other end of the weighing bucket gap connecting rod 2 is movably connected to the weighing bucket 1, and the other end of the weighing bucket gap connecting rod 2 can move up and down along the weighing bucket 1.

[0032] This embodiment is applied to automatic weighing equipment. When in use, the weighing bucket 1 is first placed on the balance 19 of the automatic weighing equipment through the weighing bucket lifting mechanism 4 and the weighing bucket turning and unloading mechanism 3. The weight of the weighing bucket 1 is peeled off. At this time, the product can be put on the weighing bucket 1 by grabbing, sucking or pouring. Then the weighing bucket lifting mechanism 4 continues to move down for a distance to ensure that the weighing bucket gap connecting rod 2 does not contact the weighing bucket 1, and weighing is performed through the balance 19. During the weighing process, since the weighing bucket gap connecting rod 2 does not contact the weighing bucket 1, the weighing bucket gap connecting rod 2 does not affect the weighing result.

[0033] After weighing is completed, the product weight information is obtained, the weighing bucket lifting mechanism 4 rises, and then the weighing bucket turning and unloading mechanism 3 turns over the weighing bucket 1 to realize unloading. After unloading is completed, the weighing bucket lifting mechanism 4 and the weighing bucket turning and unloading mechanism 3 place the weighing bucket 1 on the balance 19 of the automatic weighing equipment, and the cycle is repeated.

[0034] In this embodiment, only one weighing bucket 1 is needed for recycling, and only the weight of the weighing bucket 1 needs to be measured, and the weight is tareed each time. After the feeding device feeds the material into the inner cavity of the weighing bucket 1, the balance 19 weighs the weight of the material and the weighing bucket 1, and then the system automatically deducts the weight of the weighing bucket 1, so that the automatic weighing result can be achieved.

[0035] Furthermore, in the present embodiment, the weighing bucket 1 comprises a cylindrical weighing bucket body 5 , a groove 6 is formed in the middle of the outer circumference of the weighing bucket body 5 , and the other end of the weighing bucket gap connecting rod 2 is arranged in the groove 6 .

[0036] During weighing, the bucket gap connecting rod 2 does not contact any part of the bucket body 5 to avoid affecting the weighing. After weighing is completed, when the bucket lifting mechanism 4 rises, or when the lifting mechanism places the bucket 1 on the balance 19, the bucket gap connecting rod 2 contacts the top wall of the groove 6, which is called the force-bearing surface.

[0037] Furthermore, in this embodiment, the weighing bucket lifting mechanism 4 includes a lifting cylinder 7, a cylinder seat 8, a slider 9 and a connecting plate 10, the lifting cylinder 7 is arranged on the cylinder seat 8, the slider 9 is connected to the output shaft of the lifting cylinder 7, the lower end of the connecting plate 10 is fixedly connected to the slider 9, and one end of the weighing bucket turning and unloading mechanism 3 is connected to the upper end of the connecting plate 10.

[0038] The weighing bucket turning and unloading mechanism 3 includes a turning cylinder 11 and a connecting rod 12. The turning cylinder 11 is arranged at the upper end of the connecting plate 10. One end of the connecting rod 12 is connected to the output shaft of the turning cylinder 11, and the other end is connected to one end of the weighing bucket gap connecting rod 2.

[0039] The weighing bucket gap connecting rod 2 includes a first connecting member 13, a second connecting member 14, a semicircular clamping member 15 and an arc-shaped discharge chute 16. The tops of the first connecting member 13 and the second connecting member 14 are respectively connected to the other end of the connecting rod 12. The semicircular clamping member 15 is connected to the first connecting member 13 and is movably arranged in the groove 6. The arc-shaped discharge chute 16 is connected to the second connecting member 14 and is movably arranged in the groove 6.

[0040] In this embodiment, the inner diameter of the semicircular clamping member 15 and the arc-shaped feeding chute 16 is larger than the outer diameter of the groove 6 and smaller than the outer diameter of the top of the groove 6. During weighing, the semicircular clamping member 15 and the arc-shaped feeding chute 16 do not contact any part of the weighing bucket body 5.

[0041] The beneficial effects of the weighing device of the utility model are:

[0042] (1) The weighing device of the utility model has a simple structure, is convenient and quick to use, does not require complex actions such as positioning and grabbing or taking pictures to position and grab, and has high work efficiency;

[0043] (2) The utility model can realize the whole process of weighing by pouring materials, solving the problem that some products cannot be clamped or sucked;

[0044] (3) During the weighing process, the weighing bucket gap connecting rod 2 does not contact any part of the weighing bucket body 5, which can effectively avoid the problem of weighing error.

[0045] To achieve the above purpose, the utility model also proposes an automatic weighing device, such as Figures 1 to 8 As shown, the automatic weighing equipment includes the weighing bucket device as described in the above embodiment. The structure and working principle of the weighing bucket device have been explained in detail above and will not be repeated here.

[0046] Furthermore, in this embodiment, the automatic weighing device also includes a balance 19, and a weighing bucket centering positioning platform 17 is arranged on the top of the balance 19. A weighing bucket centering positioning structure 18 is arranged inside the weighing bucket centering positioning platform 17 for positioning the weighing bucket 1.

[0047] When in use, when the weighing bucket 1 is placed on the weighing bucket centering positioning structure 18, the weighing bucket 1 is in a centered state, ensuring that the semicircular clamping piece 15 and the arc-shaped discharge chute 16 do not contact the weighing bucket 1 in the horizontal direction, thereby avoiding affecting the weighing result.

[0048] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
