[0028] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0029] like Figure 1-6 As shown, this embodiment provides a flip-scraping weighing hopper structure, including a fixed plate 1, a weighing device 2 and a first motor 3, the fixed plate 1 is provided with a first through hole 101 and a second through hole 102, the weighing device 2 and the first motor 3 are located on one side of the fixed plate 1, the weighing device 2 is arranged in the first through hole 101, a first rotating shaft 31 extends from the first motor 3, the first motor 3 is fixed on the second through hole 102, and the first rotating shaft 31 extends out of the second through hole 102, a fixed seat 21 is installed on the weighing device 2, the weighing device can sense the weight on the fixed seat 21, a rotatable first gear 22 is installed on the fixed seat 21, a flip bucket 23 is installed on the first gear 22, a rotatable second gear 24 is arranged at the bottom of the first gear 22, and the second gear 24 and the first gear 22 are connected to each other. The first rotating shaft 31 is provided with a dial 32, and the dial 32 of the first rotating shaft 31 pushes the lever 25 to rotate, so that the second gear 24 drives the first gear 22 to rotate the overturning bucket 23, and a scraper 26 is fixed on the fixed seat 21. The shape of the scraper 26 matches the shape of the inner wall of the overturning bucket 23, so that the weighed object can be scraped out, and the first rotating shaft 31 of the first motor 3 drives the dial 32 to rotate, and the dial 32 pushes the lever 25 to rotate the second gear, and the second gear drives the first gear to rotate, so that the scraper 26 scrapes out the weighed object in the overturning bucket 23 during the rotation of the overturning bucket 23, so that the sticky weighed object will not stick to the overturning bucket 23, so that all the weighed objects that have been loaded can be put down to another device for packaging or bagging, thereby improving the accuracy of the load-bearing.

[0030] Furthermore, a balance bar 27 is provided on the outer side of the tipping bucket 23, one end of the balance bar 27 is fixed on the fixing seat 21, and the other end is fixed on the tipping bucket 23. In order to ensure that the tipping bucket 23 is in a conservative and stable state, the balance bar 27 is not easily deformed.

[0031] Furthermore, there is a gap between the dial 32 and the lever 25, and the dial 32 can only contact the lever 25 when pushing the lever 25. In order to ensure the accuracy of bearing weight, there is no contact when not rotating. If the two are in contact during bearing weight, the accuracy of bearing weight will be affected.

[0033] Furthermore, the pre-tightening assembly 28 includes a shell 281, a spring 282 and a pre-tightening block 283, the spring 282 and the pre-tightening block 283 are located in the shell 281, a first through hole is provided at the bottom of the shell 281, the end surface of the pre-tightening block 283 matches the extension column 221, the pre-tightening block 283 extends from the shell 281 to the outside of the shell 281 and contacts the extension column 221, the pressure applied by the spring allows the pre-tightening block 283 to press the extension column 221, so that the tipping bucket 23 is not easy to rotate by itself, and the stability is better.

[0034] Furthermore, a column 211 is provided on the fixed seat 21, the first gear 22 is sleeved on the column 211, the first gear 22 rotates on the column 211, a protrusion block 222 is provided on the extension column 221, and a third through hole corresponding to the protrusion block 222 is provided on the side of the tipping bucket 23. The first gear 22 rotates to allow the protrusion block 222 to push the tipping bucket 23 to rotate, and the end of the scraper 26 is fixed on the column 211, so that the scraper 26 is more stable.

[0035] Furthermore, the fixing seat 21 includes a first fixing hanging plate 223, a front hanging plate 224 and a gear fixing plate 225, wherein the gear fixing plate 225 is fixed on the front hanging plate 224, and the gear fixing plate 225 is used to install the first gear 22, the second gear 24 and the pre-tightening assembly 28, and first side plates 2231 are arranged on both sides of the first fixing hanging plate 223, and a first hanging notch 2232 and a first limiting notch 2233 arranged at the lower part of the first side plate 2231 are arranged on the first side plate 2231, and first hanging columns 2241 and second hanging columns 2242 are arranged on both sides of the front hanging plate 224, and the first hanging column 2241 is placed in the first hanging notch 2232, and the second hanging column 2242 is placed in the first limiting notch 2233.

One end of the linkage rod 551 is hinged to the second opening frame 54, and the other end is hinged to the bucket frame 52. An anti-collision rod 56 is arranged between the first opening frame 53 and the second opening frame 54. The anti-collision rod 56 is used to prevent the first opening frame 53 and the second opening frame 54 from colliding and deforming. The second motor 4 rotates the second rotating shaft 41 to lift the push rod 55, and the linkage rods 551 on both sides of the push rod 55 will pull the second opening frame 54 to rotate, and the second opening frame 54 and the first opening frame 53 move relative to each other to open, and the weighed object falls from the bottom hole under the bucket body 51 into the tipping bucket 23.

[0038] Furthermore, a second fixed hanging plate 57 is provided on the fixed plate 1, and second side plates 571 are provided on both sides of the second fixed hanging plate 57.

The first cross bar 521 is hung in the second hanging notch 572, and the second cross bar 522 is arranged in the second limiting notch 573. This structure allows the bucket frame 52 and the second fixed hanging plate 57 to be detachably connected, which is convenient for removal for replacement or cleaning.

[0039] In the prior art, the weighed objects with viscous liquid stick to the hopper after weighing and are not easy to fall off, which affects the weighing effect. Therefore, a flip-scraping weighing hopper structure is provided, in which a fixed seat 21 is installed through a weighing device 2, and a rotatable flip bucket 23 is installed on the fixed seat. The first rotating shaft 31 of the first motor 3 drives the dial 32 to rotate, and the dial 32 pushes the lever 25 to rotate the second gear, and the second gear drives the first gear to rotate, so that the scraper 26 scrapes out the weighed objects in the flip bucket 23 during the rotation of the flip bucket 23, so that the sticky weighed objects will not stick to the flip bucket 23, and the weighed objects that have been loaded can all be put down to another device for packaging or bagging, thereby improving the accuracy of the load-bearing.
