Description

Technical Field

[0001] The present invention relates to the technical field of flour production, and particularly to an automatic packing device for flour production. Background Art

[0002] Flour, also known as wheat flour, is a powdery substance obtained by grinding wheat. It is one of the common food raw materials and also one of the staple food raw materials in most areas of northern China. It is divided into two categories: grade flour and special flour according to different processing precisions and uses, and can be divided into high-gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour according to the protein content. Flour is rich in protein, carbohydrates, vitamins and minerals such as calcium, iron, phosphorus, potassium and magnesium, and has the effects of nourishing the heart and strengthening the kidney, invigorating the spleen and intestines, and removing heat and quenching thirst.

[0003] The general production process of flour includes screening, cleaning, wheat conditioning, wheat blending, grinding and packaging. Packing is an important part of the flour processing procedure, which directly affects the processing efficiency of flour. Most of the packaging of flour is manual operation. First, the workshop staff opens the opening of the flour packaging bag and sets it on the discharge pipe under the storage bin, then uses a cylinder to push the arc-shaped clip to clamp the opening of the flour packaging bag on the discharge pipe, and then opens the valve at the outlet of the discharge pipe for bagging. After the feeding is completed, the arc-shaped clip is loosened, and the flour packaging bag falls on the conveyor belt and is transported to the sealing machine for sealing treatment.

[0004] In the prior art, the packing equipment weighs the flour while bagging, and stops injecting flour into the packaging bag when the weighed weight reaches the set value. Since it is necessary to measure the flour being bagged during bagging, the workshop staff manually opens and closes the discharge port. If the workshop staff does not close the discharge port in time, the probability of excessive flour increases, thus increasing the production and processing cost of flour. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an automatic packing device for flour production to solve the technical problems in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An automatic packing device for flour production, including a device main body, a mounting seat and a powder collecting tank. The mounting seat is installed at the upper end of the device main body, and multiple groups of support columns are installed at the upper end of the mounting seat, and all multiple groups of support columns are fixedly connected to the outer wall of the powder collecting tank;

[0007] A support box is provided at the bottom end of the device main body. Two telescopic columns are movably installed inside the support box. One end of the two telescopic columns extending to the outer wall of the support box is installed with a support plate. A discharge pipe is installed at the lower discharge port of the powder collecting tank. A movable pipe is movably installed inside the inner wall of the discharge pipe. An installation disk is installed on one side of the movable pipe. The installation disk, the movable pipe and the support plate are connected by two support rods. A movable column is movably installed inside the inner wall of the installation disk. A quantitative disk is movably installed at the bottom end of the installation disk, and the center of the quantitative disk is connected to the movable column. A limiting cylinder is installed on the outer wall of one side of the discharge pipe, and the inner wall of the limiting cylinder is threadedly connected to the outer wall of the movable column. The quantitative disk is movably connected to the movable pipe, and the quantitative disk is provided with a discharge slot.

[0008] Two first conveyor belts and two second conveyor belts are movably installed inside the device main body. A plurality of placement boxes are movably arranged on the upper ends of the first conveyor belt and the second conveyor belt, and the plurality of placement boxes are respectively movably connected to the support plate.

[0009] By adopting the above technical solution, the problem of quantitative packaging of flour is solved. The placement box carries the packaging bag and moves to the upper end of the placement plate. Then, one end of the blanking slot opened in the quantitative disk is displaced to the bottom end of the movable pipe. The flour falls into the packaging bag inside the placement box through the movable pipe, making the weight of the placement box increase. The placement plate is pressed and displaced downward, thereby driving the quantitative disk to rotate, and then driving the blanking slot to displace. The blanking slot moves out of the lower end of the movable pipe, and the quantitative disk blocks the movable pipe to stop the flour from continuing to fall. The packaging bag quantitatively collects the flour, reducing the probability of excessive packaging of flour and lowering the production and processing cost of flour.

[0013] By adopting the above technical solution, when one of the second driving shafts rotates, it drives the second driving bevel gear to rotate, thereby causing the second transmission bevel gear to rotate, and then driving the second transmission shaft to rotate. Since the second transmission shaft and the first linkage shaft are connected by a synchronous belt, the first linkage shaft rotates, thus driving one of the first limiting shafts to rotate. And since the two first limiting shafts are connected by a synchronous belt, the two first limiting shafts rotate synchronously.

[0014] The present invention is further configured such that, at the other end of the mounting base, second sliding grooves are symmetrically formed.

[0015] By adopting the above technical solution, when one of the first driving shafts rotates, it drives the two first driving bevel gears to rotate, thereby driving the two first transmission shafts to rotate, and then driving the other two first transmission bevel gears to rotate. And since the other two first transmission bevel gears are respectively meshed with the two limiting bevel gears, the two limiting bevel gears rotate, thus driving the two second limiting shafts to rotate.

[0016] The present invention is further configured such that, on the outer walls of multiple placement boxes, limiting plates are symmetrically installed, and the multiple limiting plates are respectively movably connected to the two first sliding grooves and the two second sliding grooves.

Since a set of first limiting shafts 13 are connected to the first linkage shaft 17 by a synchronous belt, a set of first limiting shafts 13 rotate. And the two sets of first limiting shafts 13 are connected by a synchronous belt, so the two sets of first limiting shafts 13 rotate synchronously;

[0060] When a set of second drive shafts 7 rotate, the set of second drive shafts 7 are connected to the second movable shaft 46 by a synchronous belt, so the second movable shaft 46 rotates, thereby driving the second movable bevel gear 47 to rotate. And the second movable bevel gear 47 is meshed and connected with the linkage bevel gear 45, so the linkage bevel gear 45 rotates, thereby driving a set of contraction cylinders 42 to rotate. And the two sets of contraction cylinders 42 are connected by a synchronous belt, so the two sets of contraction cylinders 42 rotate synchronously;

[0061] When the two sets of contraction cylinders 42 rotate, the inner walls of the two sets of contraction cylinders 42 are respectively threadedly connected to the outer walls of the two sets of telescopic columns 43, so the two sets of telescopic columns 43 move upward, thereby driving the support plate 26 to move upward, further driving the two sets of support rods 25 to move upward, then driving the mounting plate 28, the movable tube 33, the movable column 30 and the metering plate 31 to move upward. And the outer wall of the movable column 30 is threadedly connected to the inner wall of the limiting cylinder 29, so the movable column 30 rotates while moving upward, thereby driving the metering plate 31 to rotate, and further driving the material discharge groove to move toward the bottom end of the movable tube 33;

[0062] When the placement box 49 moves, it drives the two sets of limiting plates 24 to move. The two sets of limiting plates 24 respectively move into the first sliding grooves 12, so that the outer walls of the upper ends of the two sets of limiting plates 24 are respectively connected to the two sets of first limiting shafts 13, and the connection method is threaded connection. So the two sets of first limiting shafts 13 respectively drive the two sets of limiting plates 24 to move, thereby driving the placement box 49 to continue to move and move to the upper end of the support plate 26. At the same time, one end of the material discharge groove moves to the lower end of the movable tube 33, and the drive motor 8 is turned off;

[0063] Flour enters the inside of the powder collecting tank 4 through the feed pipe 5. When one end of the material discharge groove moves to the lower end of the movable tube 33, the flour is discharged out of the powder collecting tank 4 through the discharge pipe 32 and the movable tube 33 and falls into the packaging bag inside the placement box 49;

[0064] Flour continuously enters the packaging bag, causing the weight of the placement box 49 to increase. The placement plate 26 is pressed and displaced downward. Due to the setting of the one-way bearing 48, one end of the second movable shaft 46 does not rotate. The placement plate 26 drives the two groups of support rods 25 to displace downward, thereby driving the quantitative plate 31 to rotate, and then driving the blanking chute to displace. The blanking chute moves out of the lower end of the movable pipe 33, and the flour is collected and quantified inside the packaging bag. The placement plate 26 continues to displace downward, causing the two groups of limit plates 24 to respectively fall into the two groups of second chutes 18. The outer walls of the lower ends of the two groups of limit plates 24 are respectively threadedly connected to the outer walls of the two groups of second limit shafts 23. And due to the flour inside the powder collecting tank 4 being continuously given weight to the quantitative plate 31 through the setting of the discharge pipe 32 and the movable pipe 33, the placement plate 26 continues to displace downward. Finally, the placement plate 26 falls onto the upper end of the support box 41;

[0065] When the two groups of support rods 25 displace downward, they drive the toothed plate 27 to displace downward. And the toothed plate 27 is meshed and connected with the movable gear 35, so the movable gear 35 rotates, thereby driving the first movable shaft 34 to rotate, and then driving the first movable bevel gear 36 to rotate. And the first movable bevel gear 36 is meshed and connected with the third driving bevel gear 38, so the third driving bevel gear 38 rotates, thereby driving the third transmission shaft 37 to rotate. And the third transmission shaft 37 is connected to the second linkage shaft 39 through a synchronous belt, so the second linkage shaft 39 rotates, thereby driving the scraper 40 to displace with the second linkage shaft 39 as the center. The scraper 40 scrapes the inner wall of the powder collecting tank 4 to prevent flour from adhering to the inner wall of the powder collecting tank 4. And one end of the second linkage shaft 39 extends into the discharge pipe 32 to loosen the flour accumulated at the discharge pipe 32, improving the flour blanking effect;

[0066] After the placement plate 26 falls onto the upper end of the support box 41, the workshop staff starts the driving motor 8, thereby driving a group of first driving shafts 6 to rotate, and then driving two groups of first driving bevel gears 19 to rotate. And the two groups of first driving bevel gears 19 are respectively meshed and connected with the two groups of first transmission bevel gears 21, so the two groups of first transmission shafts 20 rotate, thereby driving the other two groups of first transmission bevel gears 21 to rotate. And the other two groups of first transmission bevel gears 21 are respectively meshed and connected with the two groups of limit bevel gears 22, so the two groups of limit bevel gears 22 rotate, thereby driving the two groups of second limit shafts 23 to rotate;

[0067] When the two groups of second limit shafts 23 rotate, and the outer walls of the two groups of second limit shafts 23 are respectively threadedly connected to the outer bottom walls of the two groups of limit plates 24, the two groups of limit plates 24 displace, thereby driving the placement box 49 to displace, causing the placement box 49 to move to the upper end of the second conveyor belt 11. The second conveyor belt 11 transports the placement box 49 and the packaging bag inside it to the sealing machine for sealing;

[0068] Through the arrangements of the placement plate 26, the quantitative plate 31, the movable pipe 33 and the support box 41, the placement box 49 carries the packing bag and moves to the upper end of the placement plate 26. One end of the material dropping groove formed in the quantitative plate 31 is displaced to the bottom end of the movable pipe 33, and the flour falls into the packaging bag inside the placement box 49 through the movable pipe 33, so that the weight of the placement box 49 increases, and the placement plate 26 is pressed and displaced downward, thereby driving the quantitative plate 31 to rotate, and further driving the material dropping groove to displace. The material dropping groove moves out of the lower end of the movable pipe 33, and the packaging bag quantitatively collects the flour, reducing the probability of excessive packing of the flour and lowering the production and processing cost of the flour.
