Description

Technical Field

[0001] This utility model belongs to the field of flour conveying technology, and in particular relates to a flour conveying device. Background Technology

[0002] As a core raw material in the food processing industry, the airtightness, automation, and hygiene of flour's transport process directly affect production efficiency and product quality. Currently, flour is mostly transported by manually breaking open bags and pouring it into storage devices. This method has the following significant drawbacks: First, during the manual bag-tearing and pouring process, flour is easily exposed to the air, generating a large amount of dust. This not only wastes raw materials and pollutes the production environment but may also pose respiratory health risks to operators, failing to meet hygiene standards for food processing workshops. Second, manual bag-tearing is inefficient and prone to contamination due to improper operation, resulting in packaging fragments mixing into the flour.

[0003] Therefore, it is essential to invent a flour conveying device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a flour conveying device, including a storage box, a closed top cover, a dust-blocking discharge box, an observation plate, a reinforcing beam, a cutting cylinder, a cutting head, a conveying pipe, conveying blades, and a servo motor. The dust-blocking discharge box and the observation plate are installed on the closed top cover fixedly installed above the storage box. The reinforcing beam is fixedly installed inside the storage box. The output end of the cutting cylinder, which is fixedly installed outside the storage box, is fixed to the cutting head. The conveying pipe is fixedly installed on one side of the storage box. One end of the conveying blade is rotatably installed inside the storage box, and the other end of the conveying blade extends into the conveying pipe. The output end of the servo motor, which is fixedly installed outside the storage box via a motor mount, is fixed to one end of the conveying blade.

[0005] Preferably, an observation port is provided through the closed top cover that is fixedly installed on the top opening of the storage box, and the observation plate is fixedly installed at the observation port of the closed top cover by bolts. The observation plate is arranged adjacent to the dust-blocking material discharge box.

[0006] Preferably, the dust-blocking material dispensing box includes a dispensing box body, a sealing plate, a handle, a dispensing port, and a cutting groove. The lower outer wall of the dispensing box body is fixedly connected to the sealed top cover, and its lower end passes through the sealed top cover and extends into the storage box. The outer surface of the sealing plate hinged to the top of the dispensing box body is fixedly installed with a handle, and the lower end of the dispensing box body is provided with the dispensing port and the cutting groove.

[0007] Preferably, the lower part of the pouring box is an inwardly inclined, tapered structure, and the interior of the pouring box is connected to the interior space of the storage box through a pouring port at the lower end. The pouring port at the lower end of the pouring box is located on the upper side of the interior of the storage box.

[0008] Preferably, the lower end of the dispensing box has cutting slots on both sides, and the cutting slots and the cutting head are on the same horizontal line. The cutting head can cut the bottom of the flour packaging bag inside the dispensing box through the cutting slots.

[0009] Preferably, the reinforcing beam is not provided around the pouring box and the cutting head, so that the reinforcing beam does not interfere with the movement of the cutting head and does not prevent flour from falling into the storage box.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This utility model dustproof feeding box adopts a closed structure design. The feeding box body runs through the closed top cover and extends into the storage box. With the help of the hinged closing plate, the feeding process is fully enclosed, which avoids the flour being exposed to the air and generating dust. This reduces raw material waste, prevents dust from polluting the workshop environment, and also prevents external impurities from mixing into the flour, meeting food-grade hygiene requirements.

[0011] This invention utilizes a cutting cylinder to drive a cutting head, which automatically cuts the bottom of the flour packaging bag inside the feeding box through the cutting groove, replacing manual bag-breaking operations and significantly improving feeding efficiency. The cutting head and the cutting groove are precisely aligned, resulting in a stable cutting effect and avoiding the problem of packaging bag fragments being mixed in due to manual bag tearing, further ensuring the cleanliness of the raw materials.

[0012] This utility model integrates storage, automatic bag breaking, and conveying functions into one unit. One end of the conveying blade extends into the storage box, and the other end is connected to the conveying pipe. With the help of a servo motor drive, it realizes continuous operation of flour from bag breaking to conveying. The structure is compact and does not require additional transfer equipment, making it suitable for the space and production needs of small and medium-sized food processing workshops.

[0020] As attached Figure 1 To be continued Figure 3 As shown: This utility model provides a flour conveying device, including a storage bin 1, a closed top cover 2, a dust-blocking and pouring bin 3, an observation plate 4, a reinforcing beam 5, a cutting cylinder 6, a cutting head 7, a conveying pipe 8, a conveying blade 9, and a servo motor 10. The dust-blocking and pouring bin 3 and the observation plate 4 are installed on the closed top cover 2 fixedly installed above the storage bin 1. The reinforcing beam 5 is fixedly installed inside the storage bin 1. The output end of the cutting cylinder 6 fixedly installed outside the storage bin 1 is fixed to the cutting head 7. The conveying pipe 8 is fixedly installed on one side of the storage bin 1. One end of the conveying blade 9 is rotatably installed inside the storage bin 1, and the other end of the conveying blade 9 extends into the conveying pipe 8. The output end of the servo motor 10 fixedly installed outside the storage bin 1 via a motor mount is fixed to one end of the conveying blade 9.

[0021] Furthermore, a closed top cover 2 is welded to the opening at the top of the storage bin 1. The closed top cover 2 is made of food-grade 304 stainless steel sheet, and its surface is polished to meet hygiene requirements. A rectangular observation port is opened through the closed top cover 2, and the edge of the observation port is laser-cut to form a smooth bevel. The observation plate 4 is made of transparent food-grade polycarbonate (PC) sheet with a thickness of 10mm. A food-grade silicone sealing gasket is placed between the observation plate 4 and the observation port of the closed top cover 2, and the sealing is achieved by M6 stainless steel hex bolts evenly distributed around the circumference. The horizontal distance between the observation plate 4 and the dust-proof pouring bin 3 is 150mm. The two are set adjacent to each other without interfering with each other, so that the operator can check the flour storage and falling status inside the storage bin 1 in real time through the observation plate 4.

[0022] Furthermore, the dust-blocking discharge box 3 consists of a discharge box body 31, a sealing plate 32, a handle 33, a discharge port 34, and a cutting groove 35. The discharge box body 31 is integrally stamped from 304 stainless steel, and its lower outer wall is welded to the closed top cover 2 via a flange. The lower end of the discharge box body 31 vertically passes through the reserved mounting hole of the closed top cover 2 and extends into the storage box 1, with an extension length of 200mm. The sealing plate 32 is hinged to the upper part of the discharge box body 31 via stainless steel hinges. At the end opening, a food-grade silicone sealing strip is embedded in the lower edge of the sealing plate 32 to ensure the seal after closing. The handle 33 is made of ABS engineering plastic injection molding and is fixed to the center of the outer surface of the sealing plate 32 by stainless steel bolts, making it easy for operators to open and close. A rectangular pouring port 34 is opened at the lower end of the pouring box body 31. A cutting groove 35 adapted to the cutting head 7 is also opened on the side wall of the lower end of the pouring box body 31. The edge of the cutting groove 35 is polished to avoid scratching the packaging bag.

[0023] Furthermore, the lower part of the pouring box 31 is designed with an inwardly inclined 45° inward structure, and its inner wall is polished to reduce flour sticking to the wall; the interior of the pouring box 31 is connected to the interior space of the storage box 1 through the pouring port 34 set at the lower end. The lower edge of the pouring port 34 is 300mm-500mm above the bottom surface of the storage box 1, and the pouring port 34 at the lower end of the pouring box 31 is located on the upper part of the storage box 1, close to the conveying pipe 8, to ensure that the flour can be accurately guided to the feed end of the conveying blade 9 when it falls through the pouring port 34, and avoids accumulation.

[0024] Furthermore, symmetrical cutting slots 35 are opened on the side walls on both sides of the lower end of the pouring box 31. The cutting slots 35 are laser-cut. The center line of the cutting slot 35 and the center line of movement of the cutting head 7 are on the same horizontal line, and the coaxiality error between the two is ≤0.5mm. The cutting head 7 is composed of a 304 stainless steel blade (blade angle of 30°) and a food-grade POM blade holder. The cutting head 7 is threadedly connected to the piston rod of the cutting cylinder 6 through a connecting rod. The cutting cylinder 6 is fixedly installed on a stainless steel bracket outside the storage box 1, driving the cutting head 7 to reciprocate in the horizontal direction, so that it can accurately pass through the cutting slot 35 to cut the bottom of the flour packaging bag inside the pouring box 31. During the cutting process, the gap between the cutting head 7 and the cutting slot 35 is ≤0.5mm, which ensures smooth cutting and avoids flour leakage.

[0025] Furthermore, the reinforcing beam 5 is made of 304 stainless steel square tubing with a specification of 50mm×50mm×3mm. It is symmetrically fixed to the two upper side walls inside the storage box 1 by welding. The position of the reinforcing beam 5 avoids the horizontal movement trajectory of the cutting head 7, and the lower edge of the reinforcing beam 5 is ≥100mm away from the vertical height of the flour falling channel inside the storage box 1. This ensures that it will not interfere with the reciprocating movement of the cutting head 7, nor will it block the flour from falling into the storage box 1 through the discharge port 34. At the same time, it effectively enhances the structural strength of the storage box 1 and prevents it from deforming due to long-term material impact or equipment vibration.

[0026] The working principle is as follows: First, the operator opens the sealing plate 32 of the dust-blocking discharge box 3 through the handle 33, puts the packaging bag containing flour into the discharge box 31, and then closes the sealing plate 32 to maintain the sealing of the feeding environment.

[0027] Then, the cutting cylinder 6 is activated, and the cutting cylinder 6 drives the cutting head 7 to pass through the cutting slot 35 of the pouring box 31 to cut the bottom of the flour packaging bag inside the pouring box 31, so that the flour inside the packaging bag falls into the storage box 1 through the pouring port 34.

[0028] Next, the operator can observe the falling and remaining amount of flour in the storage bin 1 in real time through the observation board 4 to ensure a smooth feeding process. The reinforcing beam 5 ensures that the storage bin 1 remains structurally stable under the impact of falling flour, does not interfere with the movement of the cutting head 7, and does not block the falling channel of flour.

[0029] Then, the servo motor 10 is started, which drives the conveyor blades 9 to rotate. The flour in the storage box 1 is pushed into the conveyor pipe 8 by the conveyor blades 9, and the flour is transferred through the conveyor pipe 8.

[0030] Finally, after the flour in the packaging bag is completely emptied, the sealing plate 32 is opened again to take out the empty packaging bag, and the sealing plate 32 is closed to complete one feeding and conveying process. Throughout the process, the sealing design of the dust-blocking dumping box 3 and the sealed top cover 2 effectively prevents flour dust from escaping.

[0031] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
