[0028] The present invention will be 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 scraper 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 provided at the bottom of the first gear 22, and the second gear 24 and the teeth of the first gear 22 The first gear 23 is connected to the first rotating shaft 31, and the second gear 24 is connected to the lever 25. The first rotating shaft 31 is fixed with a dial 32. 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 tipping bucket 23. 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 tipping bucket 23, so that the weighed object can be scraped out. 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 the weighed object in the tipping bucket 23 during the rotation of the tipping bucket 23, so that the sticky weighed object will not stick to the tipping bucket 23, so that the weighed objects that have been loaded can be all put down to another device for packaging or bagging, thereby improving the accuracy of the loading.

[0030] Furthermore, a balancing rod 27 is provided on the outside of the tipping bucket 23. One end of the balancing rod 27 is fixed to the fixing seat 21, and the other end is fixed to the tipping bucket 23. In order to ensure that the tipping bucket 23 is in a conservative and stable state, the balancing rod 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.

[0035] Furthermore, the fixing seat 21 includes a first fixing hanging plate 223, a front hanging plate 224 and a gear fixing plate 225, the gear fixing plate 225 is fixed on the front hanging plate 224, the gear fixing plate 225 is used to install the first gear 22, the second gear 24 and the pre-tightening assembly 28, first side plates 2231 are provided on both sides of the first fixing hanging plate 223, a first hanging notch 2232 and a first limiting notch 2233 provided on the lower part of the first side plate 2231 are provided on the first side plate 2231, and first hanging columns 2241 and second hanging columns 2242 are provided on both sides of the front hanging plate 224, 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. This structure allows the front hanging plate 224 and the first fixing hanging plate 223 to be detachably connected, which is convenient for removal for replacement or cleaning.

[0036] like Figure 7-8As shown, a fourth through hole 103 is provided on the fixed plate 1, and a second motor 4 is provided on one side of the fixed plate 1. A second rotating shaft 41 extends from the second motor 4, and the second rotating shaft 41 extends out of the fourth through hole 103. A storage hopper 5 is provided on the fixed plate 1, and the storage hopper 5 is located above the fixed seat 21. The second rotating shaft 41 rotates to open or close the storage hopper 5. The storage hopper 5 is used to store the object to be weighed, and then placed in the tipping bucket 23 according to the predetermined weight.

[0037] Furthermore, the storage hopper 5 includes a hopper body 51, a hopper body frame 52, a first opening frame 53, a second opening frame 54 and a push rod 55. The hopper body 51 is a through structure for placing the object to be weighed. The hopper body 51 is fixed in the hopper body frame 52. The first opening frame 53 and the second opening frame 54 are located at the bottom of the hopper body 51 and open or close the bottom hole of the hopper body 51. When the first opening frame 53 and the second opening frame 54 are opened, the object to be weighed will fall from the bottom hole under the hopper body 51 into the tipping bucket 23. The two ends of the first opening frame 53 and the second opening frame 54 are hinged on the hopper body frame 52. The end positions of the first opening frame 53 and the second opening frame 54 are meshed and connected. The meshing connection can play a role. To relative movement, the push rod 55 is located at the top position of the second rotating shaft 41, and linkage rods 551 are provided on both sides of the push rod 55. 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 provided 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. 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 overturning 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.

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, objects to be weighed with viscous liquids stick to the hopper after being weighed and are not easy to fall off, thus affecting the weighing effect. Therefore, a flip-scraping weighing hopper structure is provided, wherein 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 objects to be weighed in the flip bucket 23 during the rotation of the flip bucket 23. In this way, the sticky objects to be weighed will not stick to the flip bucket 23, and all the objects to be weighed that have been loaded can be dropped into another device for packaging or bagging, thereby improving the accuracy of the loading.
