Description
Technical Field
[0001] This utility model relates to the field of additive conveying technology, and in particular to an additive weighing and sensing conveying device. Background Technology
[0002] In the fields of chemical and pharmaceutical industries, the production of raw materials usually requires the addition of a certain amount of additives to react and obtain the required materials. Additives effectively improve the production speed and quality of products to a certain extent.
[0003] In current production technology, the addition and conveying of additives are mostly carried out using conveyor belts. However, conveyor belts cannot measure the amount of additives, so the amount of additives needs to be measured manually before the conveyor belt can be used.
[0004] Therefore, an additive weighing and conveying device is proposed to weigh the additive before conveying it.
[0005] Existing additive weighing and conveying devices suffer from several drawbacks. During use, additives tend to adhere to the inner surface of the feed hopper, affecting the weighing amount and causing blockages inside the hopper. This fails to scrape and agitate the additives entering the hopper, clean the additives adhering to the inner surface, and unclog the hopper. Furthermore, when weighing additives, it is inconvenient to pour the weighed additives onto the conveying mechanism, resulting in additive residues inside the weighing mechanism.

[0012] Furthermore, a third mounting plate is fixed to the outer side of the support leg.

[0017] The additive weighing and conveying device proposed in this utility model has the following advantages:
[0018] 1. This utility model installs a scraping anti-clogging mechanism inside the feed hopper. During the process of adding additives into the feed hopper, the first motor drives the first rotating rod and the first driving gear to rotate. Through gear meshing and transmission, the first driven gear is driven to rotate, which in turn drives the scraping strip to rotate along the inner wall of the feed hopper and scrape the additives adhering to the inner surface of the feed hopper. This facilitates the cleaning of the additives adhering to the inner surface of the feed hopper, reduces the impact on the weighing of the additives, and reduces blockage inside the feed hopper. It also facilitates the smooth flow of additives for weighing. Furthermore, by disassembling and installing the locking bolts, the first driven gear and the scraping strip can be easily disassembled and installed for maintenance and replacement.
[0019] 2. This utility model installs a weighing mechanism at the bottom of the feeding hopper. Within this mechanism, a weighing plate is mounted on the top of a support plate via a telescopic rod and is intermittently mounted on the top of a weighing sensor. A second rotating rod passing through the middle of the side of the support plate is rotatably connected to the first mounting plates at both ends. Therefore, when additives fall from the feeding hopper and discharge hole onto the top of the weighing plate, causing the weighing plate to press against the top of the weighing sensor, the sensor weighs the additives. After weighing, the second motor drives the second active gear (a semi-tooth structure) to rotate, and through gear meshing, drives the second driven gear to rotate. This, in turn, causes the second rotating rod, support plate, and weighing plate to rotate 180°, completely flipping the weighing plate downwards. This facilitates the additives falling fully onto the conveyor belt, reducing additive adhesion residue inside the weighing plate. Furthermore, when the conveyor belt discharges the additives, a scraper scrapes the surface of the conveyor belt, further reducing additive adhesion residue. Afterwards, the support plate and weighing plate rotate another 180°... ° Place it horizontally upwards to receive the additive. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] For examples, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The figure shows an additive weighing and conveying device, which includes a support plate 1, a feed hopper 7 installed at the top of the support plate 1, a scraping anti-clogging mechanism installed inside the feed hopper 7, a weighing mechanism installed at the bottom of the support plate 1, and a conveying mechanism installed at the bottom of the weighing mechanism.
[0028] In detail, the scraping anti-clogging mechanism includes a scraping strip 5, a first driven gear 6, and a first driving gear 4. A flange 24 is fixed to the top of the feed hopper 7. The first driven gear 6 is slidably mounted on the top of the flange 24. A limit ring 21 is fixed to the bottom edge of the first driven gear 6. A connecting hole 26 is opened on the surface of the limit ring 21. A snap-fit bolt 8 is inserted into the internal thread of the connecting hole 26. The scraping strip 5 is obliquely fixed to the inner side of the first driven gear 6 and slidably overlaps the inner surface of the feed hopper 7. The first driving gear 4 is meshed on one side of the first driven gear 6. A first rotating rod 3 is fixedly installed in the middle of the first driving rod 4. A first motor 2 is installed at the bottom end of the first rotating rod 3.
[0029] A scraping anti-clogging mechanism is installed inside the feed hopper 7. During the process of adding additives into the feed hopper 7, the first motor 2 drives the first rotating rod 3 and the first driving gear 4 to rotate. Through gear meshing transmission, the first driven gear 6 is driven to rotate, which in turn drives the scraper 5 to rotate along the inner wall of the feed hopper 7 and scrape the additives adhering to the inner surface of the feed hopper 7. This facilitates the cleaning of the additives adhering to the inner surface of the feed hopper 7, reduces the impact on the weighing of the additives, and reduces blockage inside the feed hopper 7. This allows the additives to flow smoothly and fall into the feed hopper for weighing. Moreover, by disassembling and installing the snap-fit bolts 8, the first driven gear 6 and the scraper 5 can be easily disassembled and installed for maintenance and replacement.
[0030] The support plate 1 has a rectangular structure and is horizontally arranged. The first driven gear 6 and the first driving gear 4 are both horizontally arranged. The limiting ring 21 and the flange 24 are both annular structures and are both horizontally arranged. The limiting ring 21 is located outside the flange 24.
[0031] The connecting hole 26 is a threaded hole structure. The snap-fit bolt 8 is horizontally set, and its inner end is slidably snapped into the bottom end of the flange 24. The first rotating rod 3 is vertically set and is rotatably connected to the support plate 1. The first motor 2 is installed at the bottom end of the support plate 1.
[0032] Furthermore, the weighing mechanism includes a weighing plate 22, a support plate 14, and a weighing sensor 27. The weighing sensor 27 is fixedly installed in the middle of the support plate 14, and the weighing plate 22 is installed on the top of the weighing sensor 27.
[0033] A weighing mechanism is installed at the bottom of the feed hopper 7. In the weighing mechanism, the weighing plate 22 is installed on the top of the support plate 14 via the telescopic rod 29 and is intermittently installed on the top of the weighing sensor 27. The second rotating rod 25 passing through the middle of the side of the support plate 14 is rotatably connected to the first mounting plates 10 at both ends.
[0034] The support plate 1 has a first mounting plate 10 fixed on both sides. A second rotating rod 25 is rotatably mounted between the bottom ends of the two first mounting plates 10. The second rotating rod 25 is fixedly passed through the middle of the side of the bearing plate 14. A second driven gear 13 is fixedly mounted on one end of the second rotating rod 25. A second driving gear 28 is meshed on the top end of the second driven gear 13. A second motor 12 is mounted on one end of the second driving gear 28.
[0035] The additive falls from the feed hopper 7 and the discharge hole 23 onto the top of the weighing plate 22, causing the weighing plate 22 to press against the top of the weighing sensor 27. The weighing sensor 27 then weighs the additive. After weighing, the second motor 12 drives the second drive gear 28 with a semi-tooth structure to rotate, and through gear meshing, drives the second driven gear 13 to rotate. This, in turn, causes the second rotating rod 25, the bearing plate 14, and the weighing plate 22 to rotate 180°, so that the weighing plate 22 is completely flipped downwards. This allows the additive to fall fully onto the conveyor belt 16, reducing the adhesion and residue of the additive inside the weighing plate 22.
[0036] The weighing plate 22 and the bearing plate 14 are both rectangular structures and are horizontally arranged. The first mounting plate 10 is a rectangular plate structure and is vertically arranged. The second rotating rod 25 is horizontally arranged. The second driven gear 13 and the second driving gear 28 are both horizontally arranged. The second driving gear 28 has a half-tooth structure. The second motor 12 is installed on the outside of the first mounting plate 10.
[0037] Telescopic rods 29 are fixed at the four corners of the top of the bearing plate 14, and the top of the telescopic rods 29 are fixedly connected to the four corners of the bottom of the weighing plate 22.
[0038] Finally, the conveying mechanism includes a conveyor belt 16 and a scraper 18. The conveyor belt 16 is installed below the weighing mechanism, and the scraper 18 is installed at the discharge end of the conveyor belt 16.
[0039] The surface of the support plate 1 has a discharge hole 23, which is located at the bottom of the feed hopper 7 and directly above the weighing plate 22. It is a circular hole structure. Support legs 9 are fixed at the four corners of the bottom of the support plate 1. A second mounting plate 15 is fixed on the inner side of the support legs 9. The conveyor belt 16 is slidably mounted on the outer side of the second mounting plate 15.
[0040] A third mounting plate 20 is fixed to the outside of the support leg 9. The third mounting plate 20 is located on both sides of one end of the second mounting plate 15, and a transmission roller 19 is rotatably mounted between the two third mounting plates 20. The transmission roller 19 is inserted into one end of the conveyor belt 16, and a third motor 11 is mounted on one end of the conveyor belt 16. The third motor 11 is mounted on the outside of the third mounting plate 20.
[0041] When the additive is conveyed and discharged by the conveyor belt 16, the surface of the conveyor belt 16 is scraped by the scraper 18 to reduce the adhesion residue of the additive on the conveyor belt 16; then, the bearing plate 14 and the weighing plate 22 are rotated 180° and placed horizontally upward to receive the additive.
[0042] The other two sides of the second mounting plate 15 are fixed with fourth mounting plates 17. The scraper 18 is fixed between the two fourth mounting plates 17 and is inclined. Its top end scrapes and contacts the surface of the conveyor belt 16. The conveyor belt 16 and the second mounting plate 15 are both horizontally arranged.
[0043] Working principle: A scraping anti-clogging mechanism is installed inside the feed hopper 7. During the process of adding additives into the feed hopper 7, the first motor 2 drives the first rotating rod 3 and the first driving gear 4 to rotate. Through gear meshing transmission, the first driven gear 6 is driven to rotate, which in turn drives the scraper 5 to rotate along the inner wall of the feed hopper 7 and scrape the additives adhering to the inner surface of the feed hopper 7. This facilitates the cleaning of the additives adhering to the inner surface of the feed hopper 7, reduces the impact on the weighing of the additives, and reduces blockage inside the feed hopper 7. This allows the additives to flow smoothly and fall into the feed hopper for weighing. Moreover, by disassembling and installing the snap-fit bolts 8, the first driven gear 6 and the scraper 5 can be easily disassembled and installed for maintenance and replacement.
[0044] A weighing mechanism is installed at the bottom of the feed hopper 7. In the weighing mechanism, the weighing plate 22 is installed on the top of the support plate 14 via the telescopic rod 29 and is intermittently installed on the top of the weighing sensor 27. The second rotating rod 25 passing through the middle of the side of the support plate 14 is rotatably connected to the first mounting plates 10 at both ends.
[0045] Therefore, the additive falls from the feed hopper 7 and the discharge hole 23 onto the top of the weighing plate 22, causing the weighing plate 22 to press against the top of the weighing sensor 27. The weighing sensor 27 then weighs the additive. After weighing, the second motor 12 drives the second drive gear 28 with a half-tooth structure to rotate, and through gear meshing, drives the second driven gear 13 to rotate. This, in turn, causes the second rotating rod 25, the bearing plate 14, and the weighing plate 22 to rotate 180°, so that the weighing plate 22 is completely flipped downwards. This allows the additive to fall fully onto the conveyor belt 16, reducing the adhesion and residue of the additive inside the weighing plate 22.
[0046] Furthermore, when the additive is conveyed and discharged by the conveyor belt 16, the surface of the conveyor belt 16 is scraped by the scraper 18 to reduce the adhesion residue of the additive on the conveyor belt 16; then, the bearing plate 14 and the weighing plate 22 are rotated 180° and placed horizontally upward to receive the additive.
[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
