Description

Technical Field

[0001] The utility model relates to the field of mixing and processing equipment, and specifically relates to a premixing device for a packing scale. Background Technique

[0002] A premixing device for a packing scale is a device used to evenly mix various raw materials according to a certain proportion and perform packaging and weighing. It usually consists of a weighing system, a mixing device, and a packaging machine, so as to mix raw materials of different components according to a certain proportion and package them into finished products. Its use can improve production efficiency and ensure product quality.

[0003] Generally, for the existing premixing device for a packing scale, after various raw materials are weighed, they are transported to a mixer through a conveying device for mixing. After the mixer fully mixes various raw materials evenly, the mixed material is weighed and packaged through the conveying device.

[0004] However, the existing premixing device for a packing scale usually needs to weigh different raw materials, pour them into a stirring bin according to the proportion, stir them evenly, and then weigh and pack them. The process is cumbersome and reduces the overall work efficiency. Therefore, a premixing device for a packing scale is proposed for the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and address the problems existing in the existing equipment, the utility model proposes a premixing device for a packing scale.

[0006] The technical solution adopted by the present utility model to solve its technical problems is a premixing device for a packing scale, including: a mixing tank, on the upper shaft of which first support rods are evenly fixed, in the middle of the upper end face of the mixing tank, a support frame is fixed, a first motor is embedded in the lower end of the support frame, at the bottom of the output end of the first motor in the mixing tank, a second mixing wheel is sleeved, on both sides of the support frame, feeding bins are fixed, on both sides of the top of each feeding bin, a first rotating shaft is fixed, on both of the first rotating shafts, an adjusting plate is sleeved, on both sides of the top of the mixing tank, below the adjusting plate, second square grooves are opened, on the top of the adjusting plate, first square grooves are evenly penetrated, at the lower ends of the three first square grooves, a discharge opening is fixed, on the shafts of both of the adjusting plates, grooved plates are evenly fixed, on both sides of the mixing tank, near the adjusting plates, four second support rods are fixed, on the tops of the four second support rods, a first gear is fixed, through the centers of both of the first gears, a second rotating shaft penetrates, at the bottoms of both of the second rotating shafts, a second motor is fixed, on the tops of both of the second rotating shafts, a ring plate is fixed, on the shafts of one side of the bottoms of both of the ring plates, a second gear is embedded, at the bottoms of both of the second gears, a special-shaped shifting rod is fixed, by rotating the second motor to drive the ring plate to rotate, and then driving the second gear to rotate around the first gear, so that the special-shaped shifting rod at the lower end of the second gear is slidably clamped with the grooved plate, and then the adjusting plate is rotated, so that the discharge openings of different sizes at the bottom are located at the bottom of the feeding bin, facilitating the rapid adjustment of the raw material flow rate of different feeding bins, reducing the mixing and weighing process, and improving the working efficiency and mixing quality of mixing.

[0007] Preferably, the bottoms of the three discharge openings are proportionally scaled. By proportionally scaling the three discharge openings, it is convenient to quickly adjust the discharge flow rate of the feeding bin.

[0008] Preferably, the three first square grooves are rotationally distributed on the adjusting plate in a four-equal-part ratio. The four-equal-part ratio facilitates the closed connection between the adjusting plate where the first square groove is not opened and the bottom of the feeding bin, preventing the raw material from flowing out when changing the size of the discharge opening.

[0009] Preferably, the second gear and the first gear are meshed. Through the meshed connection, the second gear rotates around the first gear, enabling the adjusting plate to rotate when the second motor rotates.

[0010] Preferably, a first mixing wheel is sleeved in the middle of the output end of the first motor in the mixing tank. By the first mixing wheel, the falling raw material is scattered and drifted, improving the mixing uniformity efficiency.

[0011] Preferably, a lid is hinged to the top of each of the two feeding bins. The hinged lid not only facilitates the feeding of raw materials but also blocks the entry of dust.

[0012] The advantages of the present utility model are as follows: The rotation of the second motor drives the rotation of the ring plate, which in turn drives the second gear to rotate around the first gear, causing the special-shaped lever at the lower end of the second gear to be slidably clamped with the groove plate, and then causing the adjusting plate to rotate, so that the discharge openings of different sizes at the bottom are located at the bottom of the discharge bin, facilitating the rapid adjustment of the raw material flow rate of different discharge bins, reducing the mixing and weighing process, and improving the working efficiency and mixing quality of the mixing.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 As shown in the figure, a premixed material device for a packing scale includes: a mixing tank 1. First support rods 2 are evenly fixed on the shaft of the upper end of the mixing tank 1. A support frame 3 is fixed in the middle of the upper end surface of the mixing tank 1. A first motor 4 is embedded in the lower end of the support frame 3. A second mixing wheel 16 is sleeved at the bottom of the output end of the first motor 4 in the mixing tank 1. Feeding bins 5 are fixed on both sides of the support frame 3. First rotating shafts 10 are fixed on both sides of the top of the feeding bin 5. Adjusting plates 7 are sleeved on both of the two first rotating shafts 10. Second square grooves 13 are opened at the lower ends of both sides of the top of the mixing tank 1 and located below the adjusting plates 7. First square grooves 11 are evenly penetrated and opened at the top of the adjusting plates 7. A discharge port 21 is fixed at the lower ends of the three first square grooves 11. Groove plates 12 are evenly fixed on the shafts of the two adjusting plates 7. Four second support rods 14 are fixed on both sides of the mixing tank 1 near the adjusting plates 7. A first gear 8 is fixed at the top of the four second support rods 14. Second rotating shafts 17 penetrate through the centers of the two first gears 8. Second motors 18 are fixed at the bottoms of the two second rotating shafts 17. Ring plates 9 are fixed at the tops of the two second rotating shafts 17. Second gears 19 are embedded on the shafts at one side of the bottoms of the two ring plates 9. Abnormal-shaped shifting rods 20 are fixed at the bottoms of the two second gears 19.

[0023] Place different raw materials in two different feeding bins 5. According to the mixing ratio, start the second motor 18 to drive the ring plate 9 to rotate. When the ring plate 9 rotates, since the first gear 8 and the second gear 19 are meshed and connected, the second gear 19 rotates around the first gear 8. When it rotates a certain angle, the lower end of the abnormal-shaped shifting rod 20 slides into the groove plate 12. The ring plate 9 continues to rotate and then drives the adjusting plate 7 to rotate, turning the discharge port 21 with the appropriate ratio to the lower port of the feeding bin 5. Start the first motor 4 to drive the first mixing wheel 15 and the second mixing wheel 16 to rotate. When the raw materials in the two feeding bins 5 fall into the mixing tank 1, the first mixing wheel 15 scatters and drifts the two raw materials, and the second mixing wheel 16 stirs and mixes the piled-up raw materials. Then, it is quickly weighed and packed through the bottom of the mixing tank 1. The discharge port 21 is fixed by bolts and is detachable, and the discharge port 21 can be flexibly replaced for mixing and stirring with different ratios. By adjusting the flow rates at the bottoms of different feeding bins 5, it is convenient to quickly carry out mixing and stirring, improving the work efficiency.

[0024] The bottoms of the three discharging openings 21 are proportionally scaled. By proportionally scaling the three discharging openings 21, it is convenient to adjust the discharging amount of the feeding bin 5 when the raw materials fall into the mixing tank 1, and flexibly adjust the mixing ratio. The three first square grooves 11 are rotationally distributed on the adjusting plate 7 in a four-equal-part ratio. The four-equal-part ratio is convenient for the adjusting plate 7 at the place where the first square groove 11 is not opened to be hermetically connected to the bottom of the feeding bin 5, preventing the raw materials from flowing out when the size of the discharging opening 21 is changed. At the same time, the angle by which the special-shaped lever 20 drives the adjusting plate 7 to rotate is exactly such that each equally divided first square groove 11 is at the bottom of the feeding bin 5. The second gear 19 and the first gear 8 are meshed and connected. Through the meshed connection, the second gear 19 rotates around the first gear 8, enabling the rotation of the second motor 18 to make the adjusting plate 7 rotate. In the middle of the output end of the first motor 4 in the mixing tank 1, a first mixing wheel 15 is sleeved. The falling raw materials are scattered and floated by the first mixing wheel 15, improving the mixing efficiency of the mixing. The tops of the two feeding bins 5 are both hinged with a bin cover 6. The hinged bin cover 6 is not only convenient for putting in raw materials, but also convenient for blocking dust from entering.

[0025] Working principle: Place different raw materials in two different feeding bins 5. According to the mixing ratio, start the second motor 18 to drive the ring plate 9 to rotate. When the ring plate 9 rotates, due to the meshed connection between the first gear 8 and the second gear 19, the second gear 19 rotates around the first gear 8. When rotating a certain angle, the lower end of the special-shaped lever 20 slides into the groove plate 12, and the ring plate 9 continues to rotate to drive the adjusting plate 7 to rotate, turning the discharging opening 21 with the appropriate ratio to the lower port of the feeding bin 5. Start the first motor 4 to drive the first mixing wheel 15 and the second mixing wheel 16 to rotate. When the raw materials in the two feeding bins 5 fall into the mixing tank 1, the first mixing wheel 15 scatters and floats the two raw materials, and the second mixing wheel 16 stirs and mixes the piled-up raw materials, and then quickly weighs and packs through the bottom of the mixing tank 1. The discharging opening 21 is fixed by bolts and is detachable, and the discharging opening 21 can be flexibly replaced for mixing and stirring with different ratios. By adjusting the flow rate at the bottom of different feeding bins 5, it is convenient to quickly carry out mixing and stirring, improving the working efficiency.
