Description

Technical Field

[0001] The present invention relates to the field of flour processing equipment, and specifically to a feeding device for flour processing. Background Art

[0002] For flour processing and feeding, flour is one of the indispensable food products in people's daily lives. Then wheat is conveyed to a flour mill, and the flour mill grinds it to obtain coarse powder. After that, the coarse powder is screened to obtain high-quality flour. After processing and production, feeding is required. The feeding method is to stack it directly, which requires personnel to watch and manually level it to facilitate the storage cylinder to transport more flour. This is not conducive to saving labor in flour feeding. When there are too many flour processing and feeding devices, personnel will not have time to clean up the stacked flour for shipment, resulting in the spilled flour after stacking, causing waste. There is a need to use a device that can automatically balance the conveyance of flour during flour feeding, so as to save the use of labor, be able to transport flour fully loaded, and not cause problems of stacking and spilling.

[0003] Regarding the patent of the flour processing and feeding device, after retrieval, the publication number CN213325693U discloses a flour processing and feeding device, which includes an eccentric shaft arranged on a rotating disk. The eccentric shaft drives a push rod to perform a circumferential movement through a rotating sealing bearing, so as to drive a limiting plate hinged to the push rod to push forward and backward, aiming to realize the conveyance of flour in a distribution pipe to both sides of a push trolley.

[0004] Although the above device can receive or convey the flour during feeding through the push trolley, in actual use, the finished flour is generally transported and sold in bags. First, the flour is fed into the push trolley, and then transferred from the push trolley to the packaging bag, which increases the time and process of material transfer and reduces the overall production efficiency. Especially in large-scale production, this additional time cost will be more obvious. Since it is necessary to transfer the flour from the push trolley to the packaging bag, this requires additional manpower to complete, increasing the labor cost. Summary of the Invention

[0005] The purpose of the present invention is to provide a feeding device for flour processing to solve the defects mentioned in the above background art.

[0006] To achieve the above object, a blanking device for flour processing is provided, which includes a screw blanking cylinder. A screw assembly is installed inside the screw blanking cylinder. A bagging cylinder is fixedly arranged at the bottom of the screw blanking cylinder. A packaging bag is wrapped outside the bagging cylinder. A stable blanking mechanism is arranged on the circumferential outer side of the bagging cylinder. A clamping seat A is arranged on the stable blanking mechanism. The clamping seat A covers one side of the circumferential outer wall of the bagging cylinder. A clamping seat B is arranged on one side of the clamping seat A. The clamping seat B covers the other side of the circumferential outer wall of the bagging cylinder. Limit plates are fixedly arranged at both ends of the clamping seat A. A fixing seat is inserted through the end of the limit plate. A synchronous driving mechanism is installed on the fixing seat. A cylinder is screwed and installed in the middle of the surface of the fixing seat.

[0007] Further, a driving shaft is fixedly arranged on the screw assembly. A positioning seat is fixedly arranged on the circumferential outer side of the bottom of the driving shaft. A connecting arm is fixedly arranged on the circumferential outer side of the positioning seat. A powder scraping knife is fixedly arranged at one end of the connecting arm away from the positioning seat.

[0008] Further, the powder scraping knife is a trapezoidal structure made of metal. The powder scraping knife and the connecting arm are arranged in an "L" shape together. The end of the powder scraping knife is attached to the inner wall of the screw blanking cylinder. The powder scraping knife is driven to rotate through the driving shaft, the positioning seat and the connecting arm.

[0009] Further, the bagging cylinder is elliptical. The packaging bag wrapped outside the bagging cylinder is clamped and fixed by the clamping seat A and the clamping seat B. The clamping seat A and the clamping seat B move synchronously. The structures of the clamping seat A and the clamping seat B are the same. Both the clamping seat A and the clamping seat B are arc-shaped.

[0010] Further, the clamping seat B includes a rubber seat, assembling blocks and assembling grooves. The rubber seat is attached to the inner wall of the clamping seat B. Three groups of assembling blocks are evenly and fixedly arranged on the circumferential outer side of the rubber seat. Three groups of assembling grooves are evenly arranged on the circumferential inner walls of the clamping seat B and the clamping seat A. The sizes of the assembling grooves and the assembling blocks are adapted. The assembling blocks are positioned and inserted into the inside of the assembling grooves.

[0011] Further, both the assembling grooves and the assembling blocks are in a dovetail shape. Two groups of rubber seats are respectively positioned and installed on the inner walls of the clamping seat A and the clamping seat B through three groups of assembling grooves and assembling blocks. The rubber seat is arc-shaped. The inner wall radian of the rubber seat is the same as the outer wall radian of the bagging cylinder.

[0012] Further, the clamping seat A and the clamping seat B are synchronously driven to move towards each other through the synchronous driving mechanism. The synchronous driving mechanism includes a cylinder, a telescopic rod, a transmission seat, a driving arm, a driving rack, a gear, a bearing seat, a guide rod and a driven rack. A telescopic rod is arranged on the cylinder. The telescopic rod passes through the fixing seat and is fixedly connected to the middle position on the outer surface of the clamping seat B.

[0013] Further, driving arms are fixedly arranged at both ends of the circumferential outer wall of the telescopic rod. The end of the driving arm away from the telescopic rod is screwed with a driving rack. At the same time, two groups of guiding holes are evenly formed in the driving arm, and guiding rods are inserted into both groups of guiding holes. The ends of the guiding rods are fixedly arranged on the inner wall of the fixed seat.

[0014] Further, a gear is installed on one side of the driving rack. The gear is movably installed on a bearing seat, and the end of the bearing seat is fixedly arranged on the side wall of the fixed seat. A driven rack is installed on the side of the gear away from the driving rack; one side of the gear is meshed with the driving rack, and the other side of the gear is meshed with the driven rack; the surface of the fixed seat is covered with a panel, and two connecting arms are screwed and installed on the outer side wall of the fixed seat. Stable frames are welded to the ends of the two connecting arms, and a hoop is fixedly arranged at the end of the stable frame. The hoop is screwed on the circumferential outer wall of the auger feeding cylinder.

[0015] Further, the driven rack is screwed and fixed on the inner wall of the limiting plate. The limiting plate is inserted into the perforations formed at both ends of the clamping seat B. The limiting plates are arranged in two groups, and the two groups of limiting plates are symmetrically structured with respect to the telescopic rod; the limiting plates are arranged parallel to the driving rack.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The flour falling from the inside of the auger feeding cylinder of the present invention can enter the inside of the packaging bag. Since the connection position between the packaging bag and the bagging cylinder is clamped and fixed by the clamping seat A and the clamping seat B, it can be avoided that flour particles spread into the workshop during flour bagging; prevent flour from leaking from the interface, avoid extra work such as cleaning and re-bagging caused by flour leakage, make the bagging process coherent, and improve the overall production efficiency; the bagging process is more stable, avoid flour spilling or uneven bagging amount caused by the shaking and displacement of the packaging bag, and ensure that the weight of each bag of flour meets the standard; prevent flour leakage and spilling, make the flour be completely filled into the packaging bag, and reduce flour loss.

[0018] 2. By reducing or increasing the distance between the clamping seat A and the clamping seat B, the present invention can complete the clamping or releasing work of the packaging bag; the packaging bag can be directly used for bagging flour without transferring the flour from the trolley to the packaging bag, and no additional manpower is required, reducing the labor cost; the synchronous movement of the two structures of the clamping seat A and the clamping seat B can be realized by a single cylinder; compared with separately controlling the clamping seat A and the clamping seat B, the operation process is greatly simplified, the work difficulty and workload of the operator are reduced, and the operation convenience and efficiency are improved.

[0019] 3. In the present invention, the end of the flour scraping knife is attached to the inner wall of the auger feeding cylinder; since flour has a certain viscosity, it is likely to adhere to the inner wall of the auger feeding cylinder during the auger feeding process; the end of the flour scraping knife rotates while being attached to the inner wall, which can timely scrape off the adhered flour, enabling the flour to be smoothly conveyed downward along with the rotation of the auger, and avoiding the blockage or even jamming of the feeding due to the adhesion and accumulation of flour.

The packaging bag 5 wrapped around the outside of the bagging cylinder 4 is clamped and fixed by the clamping seat A61 and the clamping seat B63. The clamping seat A61 and the clamping seat B63 move synchronously, and the structures of the clamping seat A61 and the clamping seat B63 are the same; both the clamping seat A61 and the clamping seat B63 are arc-shaped.

[0040] As Figure 6 and Figure 7As shown in the figure, Specific Embodiment 5: This embodiment is a further limitation of Specific Embodiment 4. The clamping seat B63 includes a rubber seat 631, an assembling block 632 and an assembling groove 633. The rubber seat 631 is attached to the inner wall of the clamping seat B63.

[0041] As Figure 6 and Figure 7 shown in the figure, Specific Embodiment 6: This embodiment is a further limitation of Specific Embodiment 5. Both the assembling grooves 633 and the assembling blocks 632 are arranged in a dovetail shape. The two rubber seats 631 are respectively positioned and installed on the inner walls of the clamping seat A61 and the clamping seat B63 through three groups of assembling grooves 633 and assembling blocks 632. The rubber seat 631 is arranged in an arc shape, and the inner wall radian of the rubber seat 631 is consistent with the outer wall radian of the bagging cylinder 4.

[0042] As Figure 6 , Figure 7 and Figure 8 shown in the figure, Specific Embodiment 7: This embodiment is a further limitation of Specific Embodiment 6. The clamping seat A61 and the clamping seat B63 are synchronously driven to move towards each other through a synchronous driving mechanism 68. The synchronous driving mechanism 68 includes a cylinder 680, a telescopic rod 681, a transmission seat 682, a driving arm 683, a driving rack 684, a gear 685, a bearing seat 686, a guide rod 687 and a driven rack 688. The telescopic rod 681 is arranged on the cylinder 680. The telescopic rod 681 passes through the fixed seat 64 and is fixedly connected to the middle position of the outer surface of the clamping seat B63.

[0043] As Figure 6 , Figure 7 and Figure 8 shown in the figure, Specific Embodiment 8: This embodiment is a further limitation of Specific Embodiment 7. Driving arms 683 are fixedly arranged at both ends of the outer circumferential wall of the telescopic rod 681. A driving rack 684 is screwed and installed at one end of the driving arm 683 away from the telescopic rod 681. At the same time, two groups of guide holes are uniformly formed on the driving arm 683. Guide rods 687 are inserted into the interiors of the two groups of guide holes. The ends of the guide rods 687 are fixedly arranged on the inner wall of the fixed seat 64.

[0044] Working principle: During actual use, the processed flour can be discharged inside the auger hopper 1 by the auger assembly 2 during rotation, and discharged through the bagging cylinder 4. The outer side of the bagging cylinder 4 is wrapped with a packaging bag 5. The packaging bag 5 wrapped around the outer side of the bagging cylinder 4 is clamped and fixed by the clamping seat A61 and the clamping seat B63. At this time, the flour falling from inside the auger hopper 1 can enter the inside of the packaging bag 5. Since the connection position between the packaging bag 5 and the bagging cylinder 4 is clamped and fixed by the clamping seat A61 and the clamping seat B63, it can prevent the flour particles from spreading inside the workshop during flour bagging. It can prevent flour from leaking from the interface, avoid extra work such as cleaning and re-bagging caused by flour leakage, make the bagging process coherent, and improve the overall production efficiency. Workers do not need to frequently adjust or support the packaging bag 5 and can focus more on other operations, such as transporting the bagged flour and preparing new packaging bags 5, making the connection of each production link smoother. It can effectively prevent the flour from contacting the external environment too much, reduce the possibility of dust and sundries mixing into the flour, and ensure the quality and hygiene of the flour. The bagging process is more stable, avoiding flour spillage or uneven bagging amount caused by the shaking and displacement of the packaging bag 5, and ensuring that the weight of each bag of flour meets the standard. It can prevent flour leakage and spillage, enable all the flour to be filled into the packaging bag 5, reduce flour loss, and lower the raw material cost. The diffusion of flour in the workshop is reduced, the cleaning difficulty and frequency are reduced, the use of cleaning equipment, cleaning supplies and the workload of cleaning personnel are reduced, and thus the cleaning cost is reduced. It can prevent flour from entering the gaps, bearings and other parts of the bagging equipment, reduce the probability of equipment wear and failure, and extend the service life of the equipment. Since the situation of flour leaking onto the equipment is reduced, the surface of the equipment is cleaner, and it is more convenient for maintenance personnel to carry out inspections, maintenance and other work, and potential problems can be discovered and handled in time. The diffusion amount of flour particles in the workshop is reduced, the concentration of flour dust in the air is reduced, and the risk of safety accidents such as dust explosion is reduced. The driving method of the clamping seat A61 and the clamping seat B63 is as follows: Start the external switch of the cylinder 680. The output shaft of the cylinder 680 drives the telescopic rod 681 to move forward. The telescopic rod 681 drives the clamping seat B63 to move forward. At this time, the driving arm 683 fixed to the telescopic rod 681 moves forward, drives the gear 685 to rotate through the driving rack 684, and the gear 685 drives the limit plate 62 to move backward. The limit plate 62 drives the clamping seat A61 to move backward, completing the synchronous opposite movement work between the clamping seat A61 and the clamping seat B63. By reducing or increasing the distance between the clamping seat A61 and the clamping seat B63, the clamping or releasing of the packaging bag 5 is completed. The flour can be directly bagged using the packaging bag 5 without transferring the flour from the pushing trolley to the packaging bag 5, and no additional manpower is required, reducing the labor cost. The synchronous movement of the two sets of structures of the clamping seat A61 and the clamping seat B63 can be realized by one set of cylinders 680.Only by controlling a group of cylinders 680 can the synchronous movement of the clamping seat A61 and the clamping seat B63 be achieved. Compared with separately controlling the clamping seat A61 and the clamping seat B63, the operation process is greatly simplified, the work difficulty and workload of the operator are reduced, and the convenience and efficiency of operation are improved; the cylinder 680 and the synchronous drive mechanism 68 can quickly respond to operation instructions, enabling the clamping seat A61 and the clamping seat B63 to quickly reach the designated position and perform clamping and fixing, and can ensure the positioning accuracy each time, ensuring the accurate docking of the flour packaging bag and the bagging cylinder, and improving the accuracy and stability of bagging; the synchronous movement achieved by the cylinder 680 and the synchronous drive mechanism 68 can ensure that the clamping forces applied by the clamping seat A61 and the clamping seat B63 are uniform and stable, so that the flour packaging bag is always tightly connected to the bagging cylinder during the bagging process, preventing flour leakage or packaging bag detachment caused by uneven force, and ensuring the smooth progress of the bagging process; compared with using multiple independent drive mechanisms to separately control the clamping seat A61 and the clamping seat B63, the design using a group of cylinders 680 and the synchronous drive mechanism 68 is more concise, reduces the number of components of the equipment, reduces the complexity of the equipment, thereby reducing the failure points, reducing the maintenance cost and maintenance difficulty; when the equipment fails, since the number of main components involved is relatively small and the structure is relatively simple, it is easier to quickly locate the failure point, shorten the time for troubleshooting and repair, and improve the operation efficiency and reliability of the equipment; the scraping knife 32 is driven to rotate through the drive shaft 21, the positioning seat 3 and the connecting arm 31; the end of the scraping knife 32 is attached to the inner wall of the auger feeding cylinder 1; the flour has a certain viscosity and is easily adhered to the inner wall of the auger feeding cylinder 1 during the auger feeding process; the end of the scraping knife 32 rotates in contact with the inner wall, which can timely scrape off the adhered flour, enabling the flour to be smoothly conveyed downward with the rotation of the auger, avoiding the blockage of the feeding due to the adhesion and accumulation of flour; if the flour adheres to the inner wall of the auger feeding cylinder 1 for a long time, it may deteriorate due to moisture, oxidation or contact with impurities in the external environment; continuous cleaning by the scraping knife 32 can reduce the residence time of the flour on the cylinder wall and ensure the freshness and quality of the flour.
