Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and in particular to a flour conveying device for industrialized food processing. Background Art

[0002] In the industrial processing of food, the conveying and quantitative bagging of powdered materials such as flour are common processes. In the prior art, mobile equipment with screw conveyors is often used for lifting and unloading, such as the conveying device for flour production described in patent application number CN202411755032.2. However, this type of equipment faces many challenges in practical application. First, flour can easily become clogged in the storage bin (especially at the conical bottom) due to compaction or the formation of "bridges", resulting in poor material discharge. While traditional vibrators can alleviate this problem, the strong vibrations they generate are easily transmitted to the entire equipment frame, accelerating component wear and generating noise, and potentially affecting conveying stability. Second, during the vertical lifting process, the rotation of the auger can easily induce vibrations of a specific frequency. If this vibration resonates harmfully with the vibrations of the storage bin or other structures, it can exacerbate equipment shaking, affecting the positioning accuracy of the discharge pipe outlet and the uniformity of material flow. Third, flour easily adheres to the inner wall of the final discharge pipe. Long-term accumulation can lead to a reduction in the flow cross-section or even complete blockage, requiring frequent shutdowns for cleaning. Finally, the bagging process usually requires operators to manually open and hold the bag opening, which is not only inefficient and labor-intensive, but also poses health risks from prolonged operation in a dusty environment. It also makes it difficult to accurately control the bagging quantity. Summary of the Invention

[0008] Optionally, the resonance component includes a buffer column and a second buffer spring, the middle part of the support frame is in a docking state, and the two ends of the docking are slidably connected by vertical buffer columns. The lower end of the buffer column is fixedly connected to the frame body of the support frame at the lower end, and the upper end of the buffer column is slidably connected to the support frame at the upper end. The second buffer spring is mounted on the buffer column, and the second buffer spring provides an upward thrust for the upper half of the support frame.

[0009] Optionally, the scraper suspension mechanism includes a small motor, a petticoat, a rotating cylinder, a convex ring, ring teeth, gears and a scraper rod. The outer wall of the lower end of the discharge pipe is provided with a convex petticoat, and a rotating cylinder is rotated on the outer wall of the discharge pipe above the petticoat. There is a vertical small motor on the outer wall of the discharge pipe above the rotating cylinder. A gear is fixed at the lower end of the lower end of the rotating shaft of the small motor, and an annular ring tooth is provided at the upper end of the outer wall of the rotating cylinder. The ring tooth is meshed with the gear. A convex ring is fixed at the lower end of the outer wall of the rotating cylinder. Six scraper rods are distributed vertically in an annular manner along the side wall in the inner cavity of the discharge pipe.

[0010] Optionally, the scraper suspension mechanism further includes a suspension rod and a support ring. The lower end of the scraper rod is also fixedly connected downwardly to the suspension rod.

[0011] Optionally, the upper end of the bottom box is a flip-up cover.

[0012] The present invention provides a flour conveying device for industrial food processing, which has the following beneficial effects: 1. The conical structure of the base box, combined with the vibrating motor mounted on its inclined surface, effectively eliminates the "bridging" phenomenon of flour, ensuring that the powder continuously converges toward the entrance of the lifting conveyor pipe. Simultaneously, the shock-absorbing assembly (baffle, first buffer spring, and sleeve) at the lower end of the box frame effectively absorbs and isolates the longitudinal vibration energy generated by the vibrating motor through elastic deformation and sliding friction of the spring. This significantly reduces the transmission of vibration to the mobile frame and the entire device, protecting the equipment structure, extending its service life, and significantly reducing operating noise, laying the foundation for stable conveying. A spiral auger driven by the lifting motor within the lifting conveyor pipe ensures continuous and stable vertical conveying of flour from the base box to the elevated feed box.

[0013] 2. This invention utilizes a resonance component (buffer column and secondary buffer spring) positioned in the middle of the support frame to counteract the vibrations generated by the rotating auger within the lifting and conveying pipe. The upper half of the support frame slides relative to the lower half, and the elastic restoring force of the secondary buffer spring effectively dissipates vibration energy transmitted to the discharge pipe area. This design cleverly avoids harmful resonance between the lifting system's vibrations and those of the bottom box or other potential excitation sources, ensuring high stability of the discharge pipe during material descent, ensuring smooth discharge and precise bagging.

[0014] 3. The scraper suspension mechanism at the lower end of the discharge tube in this invention is driven by a small motor. Through gears meshing with ring teeth, it drives the rotating drum and six scraper rods fixed to its lower convex ring to rotate synchronously. The scraper rods continuously scrape the inner wall of the discharge tube, completely eliminating the blockage problem caused by flour clinging to the wall and clumping, ensuring unimpeded downward flow of material. Simultaneously, a suspension rod fixed to the lower end (at the curved point) of the scraper rod and a support ring attached to its lower end form an independent bag support structure. The hook-shaped design of the suspension rod's lower end, combined with the smooth support ring, allows the operator to easily and securely hook the packaging bag opening onto the support ring, achieving automatic opening and reliable suspension of the bag opening. A key advantage lies in: the rotating scraper rods (performing the anti-blocking function) and the stationary suspension rods / support rings (performing the bag support function) are driven by the same power source (a small motor driving the rotating drum), yet they function independently and independently of each other: the scraper rods rotate to clear the tube wall, while the suspension rods / support rings remain stationary to provide stable support. The petticoat provides a reliable support point at the bottom of the rotating drum. This design achieves two goals at once: it frees the operator's hands, significantly improves bagging efficiency, operation convenience and safety, and reduces labor intensity.

[0027] The upper end of the bottom box 3 is a flippable cover.

[0028] The following further explains and illustrates the functions and effects of each structure in the above content, so that those skilled in the art can better understand the technical solution: The mobile frame 1 constitutes the basic mobile platform of the entire device. The universal wheels 101 arranged at the four corners of the bottom enable the device to be easily and flexibly moved and positioned in the processing workshop, greatly improving the applicability and convenience of the equipment. The box frame 2 is fixed to one end of the mobile frame 1, mainly carrying the bottom box 3. The bottom box 3 serves as the initial storage and buffer container for flour. Its lower end is designed to be a conical structure that is wide at the top and narrow at the bottom. This shape is conducive to the natural convergence of flour to the outlet under the action of gravity, reducing residue; the vibration motor 301 installed on the bottom slope of the bottom box 3 can generate vibrations of a specific frequency, effectively preventing flour from compacting or bridging at the bottom of the cone, ensuring that the powder flows downward continuously and evenly. In order to isolate the negative impact of the vibration motor 301 on the overall structure, a shock-absorbing assembly is provided at the lower end of the box frame 2, which consists of a baffle 201, a first buffer spring 202 and a sleeve column 203: the vertical rod of the box frame 2 can slide in the sleeve column 203, the baffle 201 is fixed on the vertical rod, and the first buffer spring 202 is sleeved between the baffle 201 and the sleeve column 203, always providing an upward thrust, thereby absorbing and buffering the vibration from the bottom box 3 and the vibration motor 301, protecting the overall stability of the device and extending the life of the components, while reducing noise.

[0029] Flour is lifted vertically from the bottom bin 3 to a higher elevation for discharge via a lifting pipe 4. The lower end of the lifting pipe 4 connects to the bottom bin 3, while the upper end leads to the feed box 6. A lifting motor 401 drives the internal lifting shaft 402, which rotates against the inner wall of the lifting pipe 4. This efficient spiral conveying mechanism propels the flour from the bottom bin 3 steadily and continuously upward to the feed box 6. The feed box 6 is fixed to one side of the discharge pipe 7 near its upper end and tilted downward to one side, smoothly directing the flour from the lifting pipe 4 and injecting it into the discharge pipe 7 below.

[0030] The discharge pipe 7 is the channel through which the flour finally flows out, and its upper end is supported by the support frame 5 fixed to the other end of the mobile frame 1. Taking into account that the vibration that may be generated by the rotation of the auger 403 in the lifting and conveying pipe 4 will be transmitted to the support frame 5 and the discharge pipe 7, a resonance component is set in the middle of the support frame 5, which includes a buffer column 501 and a second buffer spring 502. The middle part of the support frame 5 is a relatively slidable docking structure, which is connected by the buffer column 501. The second buffer spring 502 is mounted on the buffer column 501 and provides an upward thrust. This design can effectively absorb and dissipate the vibration energy transmitted to the upper part of the support frame 5, prevent it from generating harmful resonance with other parts of the device (such as the vibration motor 301), and ensure the stability of the discharge pipe 7 and the smoothness of the discharge.

[0031] One of the device's most critical innovations is the scraper suspension mechanism located at the lower end of the discharge tube 7. This mechanism integrates two functions: anti-clogging and bag-supporting. Its core components include a drive unit and an actuator. A small motor 701 is fixed above the outer wall of the discharge tube 7. Its output shaft drives a gear 706. Gear 706 engages with a ring gear 705 fixed to the upper end of the outer wall of the rotating drum 703, thereby driving the rotating drum 703 to rotate around the outer wall of the discharge tube 7. A raised ring 704 is fixed to the lower end of the outer wall of the rotating drum 703. Within the inner cavity of the discharge tube 7, multiple (e.g., six) scraper rods 707 are distributed in a ring along the sidewall. The lower ends of the scraper rods 707 are fixed to the raised ring 704. When the small motor 701 drives the rotating drum 703 to rotate, the raised ring 704 drives all scraper rods 707 to rotate synchronously along the inner wall of the discharge tube 7. The scraper rod 707 continuously scrapes the inner wall of the discharge tube 7, effectively breaking up any flour buildup, lumps, or blockages that may form on the tube wall, ensuring smooth downward flow of flour. Furthermore, the lower end of the scraper rod 707 is designed as an arc-shaped structure that bends outward toward the discharge tube 7. A suspension rod 708 extends downward and connects to it. The lower end of the suspension rod 708 further bends outward approximately 150 degrees to form a hook-like structure. A smooth support ring 709 is fixedly connected between the lower ends of all suspension rods 708. When filling flour into a bag, the operator can place the edge of the bag opening over the support ring 709. The curved structure of the suspension rod 708 and the support ring 709 ensure a stable opening of the bag, freeing the operator's hands to focus on controlling the bagging process, significantly improving bagging efficiency, convenience, and safety. A petticoat 702, located on the outer wall of the lower end of the discharge tube 7, provides a stable and reliable rotational support point for the rotating drum 703.

[0032] Working principle: When the device is in operation, the operator first pushes the device to the designated workstation via the universal wheels 101 at the bottom of the mobile frame 1. After opening the reversible cover at the top of the bottom box 3 and injecting flour, the vibration motor 301 and the lifting motor 401 are started. The specific frequency vibration generated by the vibration motor 301 acts on the conical slope of the bottom box 3, effectively destroying the bridging phenomenon of the flour and causing the powder to converge toward the entrance of the lifting conveying pipe 4. At the same time, the shock-absorbing assembly at the lower end of the box frame 2 (composed of a baffle 201, a first buffer spring 202, and a sleeve 203) absorbs longitudinal vibration energy through the elastic deformation of the spring. The baffle 201 slides within the sleeve 203 along with the vertical rod of the box frame 2. The first buffer spring 202 continuously provides an upward reaction force, significantly isolating the transmission of vibration to the mobile frame 1, ensuring stable operation of the equipment and reducing noise. The flour in the bottom box 3 enters the lifting and conveying pipe 4 under the action of gravity and vibration. The lifting shaft 402 is driven by the lifting motor 401 to drive the spiral auger 403 to rotate. The edge of the auger 403 is close to the pipe wall to push the flour upward continuously. The flour is output to the inclined feed box 6 through the upper end of the lifting and conveying pipe 4, and the flour naturally slides into the vertical discharge pipe 7.

[0033] During the flour conveying process, when the vibration generated by the rotation of the auger 403 within the lifting and conveying pipe 4 is transmitted to the support frame 5, the resonance assembly within it (comprising a buffer column 501 and a second buffer spring 502) comes into play. The upper half of the support frame 5 slides relative to the lower half via the buffer column 501. The elastic restoring force of the second buffer spring 502 dissipates the vibration energy, preventing harmful resonance with the vibration of the bottom box 3 and ensuring the stability of the discharge pipe 7. As the flour falls along the discharge pipe 7, the small motor 701 of the scraper suspension mechanism is simultaneously activated. The meshing transmission between the gear 706 and the ring gear 705 drives the rotating drum 703 to rotate around the pipe wall. The raised ring 704 at the lower end of the rotating drum 703 drives six annular scraper rods 707 to rotate synchronously within the discharge pipe 7. The scraper rods 707 continuously scrape away flour adhering to the pipe wall, completely eliminating the problem of powder blockage. When flour flows to the pipe opening for bagging, the operator places the edge of the bag opening onto the support ring 709. The 150-degree outward-bent hook structure of the suspension rod 708, extending from the lower end of the scraper rod 707, hooks the bag opening, forming a stable ring-shaped support with the smooth support ring 709, freeing the operator's hands. While the rotating scraper rod 707 continuously clears the pipe wall, the suspension rod 708 and support ring 709 remain stationary (because the suspension rod 708 is only fixed to the lower end of the scraper rod 707 and does not rotate), achieving simultaneous and independent operation of the anti-clogging and bag-supporting functions. The petticoat 702 provides stable bottom rotational support for the rotating drum 703. This device achieves efficient and coordinated operation throughout the entire process of movement, material storage, anti-clogging lifting, shock absorption and flow stabilization, scraping and clearing, and bag-supporting and filling.
