Description

Technical Field

[0001] This application relates to the technical field of equipment for producing filamentous foods, specifically a vibrating hopper for producing filamentous foods. Background Technology

[0002] In the automated packaging production of shredded foods, especially Sichuan rice noodles and wide rice noodles, vibrating hoppers are key equipment for feeding and bagging. Currently, the vibrating hoppers commonly used in the industry rely on vibrating motors as the excitation source. These vibrating motors generate centrifugal force through the rotation of internal eccentric blocks, thereby driving the hopper to perform high-frequency, micro-amplitude directional linear vibration.

[0003] However, this traditional vibration method has the following limitations when processing long, tangled, and brittle materials such as filamentous foods:

[0004] 1. High-frequency rigid vibration and impact can easily cause the vermicelli to collide and break, producing a large amount of debris, which affects the product appearance and yield.

[0005] 2. Simple linear vibration has limited effect on untangling intertwined filamentous food clumps. The material is prone to "bridging" or "arching" at the hopper outlet, resulting in poor material discharge, requiring manual intervention and affecting packaging efficiency.

[0006] 3. The vibration parameters (such as frequency and amplitude) of traditional vibratory motors have a limited adjustment range, making it difficult to flexibly adapt to the production needs of filamentous foods of different specifications (such as length and dryness).

[0007] Therefore, there is an urgent need in this field for a vibrating hopper that can achieve gentle and efficient feeding and significantly reduce material breakage rate. Summary of the Invention

[0008] In order to overcome the shortcomings of the prior art, this utility model discloses a vibrating hopper for the production of filamentous food. This utility model can not only fundamentally reduce the breakage and debris generation of filamentous food during vibration, but also effectively destroy the stable arch bridge structure formed by the filamentous food in the discharge hopper, thus solving the problem of material blockage.

[0009] To achieve the above objectives, this application provides the following technical solution:

[0010] A vibrating hopper for producing filamentous food products includes a base and further includes:

[0011] The support rod is vertically installed on the upper part of the base;

[0012] The movable frame is mounted on the support rod and can be raised and lowered along the support rod.

[0013] The hopper, located on one side of the movable frame, has an open structure at both the top and bottom, and is used to load and feed filamentous food.

[0014] The vibration mechanism is located on the other side of the movable frame. The vibration mechanism includes a drive motor, a crank, a connecting rod, and a connecting rod. The drive motor is fixed on the movable frame, and its output end is connected to the crank. The upper end of the connecting rod is hinged to the crank. One end of the connecting rod is hinged to the lower end of the connecting rod, and the other end of the connecting rod is fixedly connected to the hopper. It is used to convert the rotational motion of the drive motor into a composite nonlinear vibration that drives the hopper.

[0015] An opening and closing mechanism is located at the lower opening of the hopper and controls the opening and closing of the lower opening of the hopper.

[0016] Furthermore, the movable frame includes:

[0017] The movable seat is mounted on the support rod in a height-adjustable manner;

[0018] The mounting plate is vertically installed on the upper part of the movable base;

[0019] A rectangular frame is located on one side of the mounting plate, with its lower end being an open structure;

[0020] The drive motor is located on one side of the rectangular frame, the crank and connecting rod are located inside the rectangular frame, and the connecting rod is located at the bottom of the rectangular frame.

[0021] Furthermore, a movable plate is fixedly installed on the upper part of the connecting rod, and the movable plate slides in conjunction with the side wall of the rectangular frame to constrain the movement trajectory of the connecting rod.

[0022] Furthermore, the opening and closing mechanism includes:

[0023] Two baffles are positioned opposite each other at the lower opening of the hopper. Each baffle includes a baffle plate and connecting plates located at both ends of the baffle plate and perpendicular to the baffle plate. The connecting plates at both ends of the baffle plate are respectively hinged to the side walls on both sides of the hopper.

[0024] The telescopic cylinder, located on one side of the hopper, is used to drive two stops to rotate synchronously in opposite directions or in opposite directions.

[0025] Furthermore, the telescopic cylinder is vertically installed on one side of the hopper, and its output end is hinged to two drive rods that are parallel to the connecting plates at the ends of the two stop components. The lower ends of the two drive rods are connected to the corresponding connecting plates.

[0026] Furthermore, meshing teeth are provided on the mating surfaces of adjacent connecting plates between the two stops.

[0027] Furthermore, the support rod has multiple mounting holes spaced apart along its axial direction. The movable seat is fixed through mounting holes of different heights to achieve the lifting and lowering adjustment of the movable seat.

[0028] Furthermore, the upper opening of the hopper is equipped with an enlarged diameter enclosure.

[0029] Compared with the prior art, the beneficial effects of this application are:

[0030] This invention utilizes a vibration mechanism comprised of a drive motor, crank, connecting rod, and linking rod to successfully convert the rotational motion of the motor into a composite nonlinear vibration of the hopper. Compared to the high-frequency rigid impact of traditional vibratory motors, this design allows for gentler energy transfer, fundamentally reducing breakage and debris generation in filamentous foods during vibration. It also generates effective pulling and shearing forces on the filamentous foods, thoroughly untangling intertwined strands and effectively disrupting the stable arch structure formed by the filamentous foods in the discharge hopper, thus completely solving the problem of material blockage. Furthermore, the vibration amplitude can be altered by adjusting the connection point of the linking rod on the crank, allowing for rapid adaptation to filamentous food products of different lengths, thicknesses, and moisture levels, making it highly versatile. This invention features a simple structure and convenient operation, providing strong support for the high-efficiency and high-quality production of filamentous foods. Attached Figure Description

[0035] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0036] Please refer to the instruction manual appendix. Figure 1-3 This utility model provides a technical solution:

[0037] Example 1: A vibrating hopper for producing filamentous food includes a base 1, a support rod 2 vertically arranged on the upper part of the base 1, and a movable frame 3 that can be adjusted up and down along the support rod 2. Specifically, the movable frame 3 includes a movable seat 3.1 that can be raised and lowered on the support rod 2, a mounting plate 3.2 vertically arranged on the upper part of the movable seat 3.1, and a rectangular frame 3.3 located on one side of the mounting plate 3.2 with an open structure at its lower end.

[0038] A rectangular frame 3.3 has a hopper 5 on one side, open at both ends, for loading and dispensing filamentous food. The upper part of the hopper 5 has an enlarged diameter baffle 5.1. The lower part of the hopper 5 has an opening and closing mechanism 6 for controlling the opening and closing of the lower part of the hopper 5. The other side of the rectangular frame 3.3 has a vibration mechanism 4 for driving the hopper 5 to perform compound nonlinear vibration. Specifically, the vibration mechanism 4 includes a drive motor 4.1, a crank 4.2, a connecting rod 4.3, and a connecting rod 4.4. The drive motor 4.1 is fixed to the outside of the rectangular frame 3.3, and its output end extends into the rectangular frame 3.3 and is connected to the crank 4.2. The upper end of the connecting rod 4.3 is hinged to the crank 4.2. The connecting rod 4.4 is located at the lower part of the rectangular frame 3.3, with one end hinged to the lower end of the connecting rod 4.3 and the other end fixedly connected to the hopper 5. The crank 4.2 and connecting rod 4.3 can convert the rotational motion of the drive motor 4.1 into compound nonlinear vibration of the hopper 5. Linear vibration, combined with nonlinear vibration, is more like a "kneading" or "bumping," slowly lifting and lowering the filamentous food in hopper 5, and oscillating it during the process to loosen it. This vibration feeding method for filamentous food not only has a gentler motion, greatly reducing the breakage rate and debris generation of the filamentous food, but also generates pulling and shearing forces on the filamentous food. It is more effective than simple vertical vibration in untangling filamentous food and can more thoroughly solve the problems of "bridging" and blockage. In addition, by changing the speed of the drive motor 4.1, the vibration "frequency" (i.e., the number of bumps per minute) can be easily and linearly adjusted. By changing the connection point of the connecting rod 4.3 on the crank 4.2, the motion "amplitude" (i.e., the amplitude of lifting, lowering and oscillation) can be changed. This independent adjustability of frequency and amplitude makes it better adaptable to filamentous food products of different lengths, thicknesses and moisture levels, making it more versatile.

[0039] In Example 2, during the vibration feeding operation of the vibrating mechanism 4 into the hopper 5, the movement trajectory of the hopper 5 will be unpredictable and non-repetitive. It may violently swing and twist like a pendulum instead of vibrating steadily, which is not conducive to the stable feeding operation of the filamentous food. Therefore, a movable plate 4.5 is fixedly installed on the upper part of the connecting rod 4.4. The movable plate 4.5 slides with the side wall of the rectangular frame 3.3. The sliding engagement between the movable plate 4.5 and the rectangular frame 3.3 acts as a "guide rail" or "sliding bearing". The function of the connecting rod 4.4 is to constrain its motion trajectory. This not only effectively eliminates the rotational degree of freedom of the connecting rod 4.4 in the horizontal plane, as well as most of the unnecessary lateral translational degree of freedom, but also allows the connecting rod 4.4 to move freely up and down along its axis. At the same time, since the upper end of the connecting rod 4.3 is making circular motion, it will push the constrained connecting rod 4.4 to tilt back and forth or left and right in the vertical plane. The movable plate then guides and transforms the originally chaotic oscillation into a definite and repeatable composite motion, enabling the hopper 5 to perform a gentle, controllable composite nonlinear vibration with "bumping" and "kneading" effects.

[0040] In embodiment three, to achieve stable opening and closing control of the lower opening of the hopper 5, the opening and closing mechanism 6 includes two stops 6.1 and a telescopic cylinder 6.2. Specifically, the stops 6.1 include a baffle 6.1.1 and connecting plates 6.1.2 disposed at both ends of the baffle 6.1.1 and perpendicular to the baffle 6.1.1. The connecting plates 6.1.2 at both ends of the baffle 6.1.1 are respectively hinged to the side walls on both sides of the hopper 5. The two stops 6.1 are arranged opposite to each other. The telescopic cylinder 6.2 is disposed on one side of the hopper 5 and is used to drive the two stops 6.1 to rotate synchronously in opposite directions or in opposite directions. Specifically, the telescopic cylinder 6.2 is vertically disposed on one side of the hopper 5, and its output end is hinged to two connecting plates 6.1 respectively connected to the ends of the two stops 6.1. 1.2 Parallel drive rods 6.3, the lower ends of the two drive rods 6.3 are respectively connected to the corresponding connecting plates 6.1.2. By moving the output end of the telescopic cylinder 6.2 downward, the lower ends of the two drive rods 6.3 are moved away from each other, thereby driving the two stops 6.1 to move in opposite directions, realizing the opening of the lower opening of the hopper 5, and conversely, closing the lower opening of the hopper 5. In order to ensure that the two stops 6.1 can be precisely controlled to open and close, the mating surfaces of the adjacent connecting plates 6.1.2 between the two stops 6.1 are provided with meshing teeth 6.1.2.1. The meshing teeth 6.1.2.1 enable the two stops 6.1 to open and close at a more precise and stable angle.

[0041] The opening and closing mechanism 6 drives the hinged stop 6.1 on both sides through a single telescopic cylinder 6.2, realizing the synchronous and precise opening and closing of the outlet of the hopper 5. This structure not only utilizes the rigidity of the stop 6.1 itself and the interlocking of the meshing teeth 6.1.2.1 on the mating surface to ensure stability and sealing when closing, effectively preventing the leakage and jamming of the powder, but also its fully hinged design is perfectly decoupled from the vibration system. While achieving efficient and stable control, it does not affect the core composite nonlinear vibration effect of the hopper 5 at all.

[0042] In Example 4, in order to achieve the lifting and lowering adjustment of the movable frame 3, the support rod 2 is provided with a plurality of mounting holes 2.1 spaced apart along its axial direction, and the movable seat 3.1 is provided with through holes that are adapted to the mounting holes 2.1. The corresponding mounting holes 2.1 and through holes are provided with mounting bolts. The movable seat 3.1 is fixed through the mounting holes 2.1 at different heights, thereby realizing the lifting and lowering adjustment of the movable seat 3.1.
