Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a quantitative feeding funnel for granular food. Background Technology

[0002] Food processing is the process of transforming raw materials (such as meat, vegetables, grains, etc.) into food products with specific flavor, texture, nutritional value, and shelf life through a series of physical, chemical, or biological treatment processes, including washing, cutting, marinating, cooking, shaping, and packaging, for direct human consumption or further processing. In the process of meatball processing, a feeding funnel is used to feed the meatballs to ensure that they can enter the next processing stage, such as cooking or packaging, evenly and orderly, thereby improving production efficiency and product quality.

[0003] An existing patent (publication number: CN217805567U) discloses a quantitative feeding funnel for granular food, comprising a funnel body, an inlet at the top of the funnel, an outlet at the bottom of the funnel body, a gantry frame mounted on the outer side of the top of the funnel body, a quantitative valve mounted on the bottom of the funnel body, and a lifting structure located in the middle of the top of the funnel body. The lifting structure includes a knob, a lead screw, and a limiting block. The knob is located in the middle of the gantry frame, the lead screw passes through the gantry frame and is fixedly installed at the bottom of the knob, the limiting block is fixedly installed at the bottom end of the lead screw, and an anti-clogging structure is provided on the top of the knob. This utility model's quantitative feeding funnel for granular food effectively prevents food accumulation in the funnel by controlling the quantity and speed of granular food falling. Furthermore, when the outlet is blocked, the anti-clogging structure can clear the blockage, improving the efficiency of food production and processing.

[0004] During use, the feeding hopper allows the material to be fed by adjusting the gap between the conical limiting block and the hopper body, thus allowing individual materials to pass through. However, when feeding meatballs, some meatballs may stick together due to the presence of tendons inside, which can easily block the gap between the limiting block and the hopper body, resulting in poor material discharge. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quantitative feeding funnel for granular food, which has advantages such as anti-clogging and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a granular food quantitative feeding funnel, comprising a hopper, wherein the hopper is provided with a block for adjusting the feeding amount, the block having an inverted conical structure, a support fixedly connected to the upper end of the hopper, a threaded cylinder rotatably connected to the bottom end of the support, the upper end of the block at the bottom end of the threaded cylinder being threadedly connected, and a rotating rod rotatably connected inside the threaded cylinder.

[0007] The bottom of the block has multiple circumferentially distributed cavities, each of which has a slidably connected cutting block inside. Each cutting block is connected to the rotating rod through a drive assembly.

[0008] Furthermore, two guide rods are fixedly connected to the upper surface of the block, and both guide rods are vertically slidably inserted into the bracket.

[0009] The above scheme provides guidance for the vertical lifting and lowering of the block, enabling the block to rise and fall vertically in a stable manner.

[0010] Furthermore, the drive assembly includes a rotating ring rotatably connected to the inner wall of the hopper. Multiple circumferentially distributed top blocks are fixedly connected to the circumferential surface of the rotating ring. Insert rods are fixedly connected to one side of each of the multiple cutting blocks, and each insert rod passes through the cavity and contacts the rotating ring.

[0011] With the above scheme, the inserted rod can push the cutting block out through the contact between the top block and the inserted rod during the rotation of the rotating ring, thereby cutting the meatball stuck in the gap between the block and the inner wall of the hopper. The cut meatball passes through the gap and is discharged from the bottom of the hopper, preventing the meatball from blocking the gap between the block and the hopper and ensuring the normal feeding function of the funnel.

[0012] Furthermore, each of the top blocks is chamfered, and the end of each insert near the rotating rod is spherical.

[0013] The above solution, which involves chamfering the top block and making one end of the insertion rod spherical, makes the contact between the top block and the insertion rod smoother and reduces friction and jamming.

[0014] Furthermore, the drive assembly also includes multiple circumferentially distributed limiting plates hinged to the inner wall of the rotating ring, each limiting plate having a sliding groove on its side, and multiple circumferentially distributed sliding frames hinged to the circumferential surface of the rotating rod, with the upper end of each sliding frame located inside the corresponding sliding groove and slidably connected to the corresponding sliding groove.

[0015] The above scheme, with its limiting plate, sliding groove, and sliding frame, ensures that during the rotation of the rotating rod, the rotating rod can drive the rotating ring to rotate through the limiting plate and sliding frame. After the height of the blocking block is adjusted, the sliding frame can slide in the sliding groove, and the linkage can still be maintained even after the height of the blocking block is adjusted.

[0016] Furthermore, the drive assembly also includes multiple springs that are fixedly connected to the sides of the cut blocks, each spring being sleeved with a corresponding insert rod and fixedly connected to the inner wall of the cavity.

[0017] With the above solution, the spring can automatically retract into the cavity after the meatball is cut, thanks to the spring's elastic restoring force.

[0018] Furthermore, an auger is fixedly connected to the bottom end of the rotating rod, and the auger is coaxially arranged with the rotating rod and extends into the discharge hopper.

[0019] The above solution allows the auger to further assist in feeding. The rotating auger can push the meatballs at the bottom of the hopper to fall smoothly, preventing the meatballs from accumulating and blocking the bottom of the hopper.

[0020] Furthermore, there is a gap between the auger and the inner wall at the bottom of the hopper.

[0021] Through the above scheme, the gap forms a channel in which materials can flow more freely. When the auger rotates and pushes the materials, the materials can be smoothly discharged downwards along the gap without accumulating due to the narrow space. When the bottom of the hopper is blocked, the movement of the auger can clear the blockage at the bottom of the hopper.

[0022] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0023] This quantitative feeding funnel for granular food, through the combination of a blocking block and a threaded cylinder, allows for flexible adjustment of the gap between the blocking block and the inner wall of the hopper. It can precisely control the size of the feeding channel according to meatballs or other granular foods of different diameters. Furthermore, the auger can clear the bottom of the hopper during its movement, preventing material from clogging when passing through the narrow bottom of the hopper. Secondly, when meatballs stick together, the rotating ring in the drive assembly rotates under the drive of the rotating rod, and the top block contacts the insertion rod, pushing the cutting block to extend out of the cavity, cutting the sticky meatballs and allowing them to pass smoothly through the gap between the hopper and the blocking block.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Please see Figures 1-5 This embodiment of a granular food quantitative feeding funnel includes a hopper 1. The hopper 1 has a plug 2 for adjusting the feeding amount inside. The plug 2 has an inverted conical structure. A support 3 is fixedly connected to the upper end of the hopper 1. A threaded cylinder 4 is rotatably connected to the bottom end of the support 3. The bottom end of the threaded cylinder 4 is threadedly connected to the upper end of the plug 2. A rotating rod 5 is rotatably connected inside the threaded cylinder 4. By cooperating with the plug 2 and the threaded cylinder 4, the gap between the plug 2 and the inner wall of the hopper 1 can be adjusted by rotating the threaded cylinder 4, thereby allowing meatballs of different diameters to pass through. Two guide rods 9 are fixedly connected to the upper surface of the plug 2. Both guide rods 9 are vertically slidably inserted into the support 3. The guide rods 9 can provide guidance for the vertical lifting and lowering of the plug 2, so that the plug 2 can be stably lifted and lowered vertically.

[0035] The bottom of the block 2 has multiple circumferentially distributed cavities 6. Each cavity 6 has a slidably connected cutting block 7. Each cutting block 7 is connected to the rotating rod 5 through a drive assembly 8. When the meatballs stick together, the cutting block 7 can be driven by the drive assembly 8 to extend and cut the sticky meatballs, allowing the meatballs to pass through the gap between the hopper 1 and the block 2, effectively solving the problem of poor feeding caused by sticky meatballs.

[0036] The drive assembly 8 includes a rotating ring 801 rotatably connected to the inner wall of the hopper 1. Multiple circumferentially distributed top blocks 802 are fixedly connected to the circumferential surface of the rotating ring 801. Insert rods 803 are fixedly connected to one side of each of the multiple cut pieces 7. Each insert rod 803 passes through the cavity 6 and contacts the rotating ring 801. During the rotation of the rotating ring 801, the contact between the top blocks 802 and the insert rod 803 allows the insert rod 803 to push the cut piece 7 outwards, thereby discharging the material stuck in the block 2 and the material... The meatballs in the gap inside the hopper 1 are cut off, and the cut meatballs pass through the gap and are discharged from the bottom of the hopper 1, preventing the meatballs from clogging the gap between the block 2 and the hopper 1, thus ensuring the normal feeding function of the funnel. Each top block 802 is chamfered, and the end of each insert rod 803 near the rotating rod 5 is spherically shaped. The chamfering of the top block 802 and the spherical shape of one end of the insert rod 803 make the contact between the top block 802 and the insert rod 803 smoother and reduce friction and jamming. The drive assembly 8 also includes a rotating rod. The inner wall of the rotating ring 801 is hinged with multiple circumferentially distributed limiting plates 804. Each limiting plate 804 has a sliding groove 805 on its side. The circumferential surface of the rotating rod 5 is hinged with multiple circumferentially distributed sliding frames 806. The upper end of each sliding frame 806 is located inside the corresponding sliding groove 805 and is slidably connected to the corresponding sliding groove 805. The limiting plates 804, sliding grooves 805, and sliding frames 806 ensure that the rotating rod 5 can move freely between the limiting plates 804 and the sliding frames 806 during rotation. The drive rotating ring 801 rotates, and after the height of the block 2 is adjusted, the sliding frame 806 can slide in the slide groove 805. After the height of the block 2 is adjusted, the linkage can still be maintained. The drive assembly 8 also includes multiple springs 807 that are fixedly connected to the sides of the cutting blocks 7. Each spring 807 is sleeved with the corresponding insert rod 803 and fixedly connected to the inner wall of the cavity 6. The setting of the springs 807 can make the cutting blocks 7 automatically retract into the cavity 6 by using the elastic restoring force of the springs 807 after the cutting blocks 7 complete the action of cutting the meatball.

[0037] A screw conveyor 10 is fixedly connected to the bottom end of the rotating rod 5. The screw conveyor 10 is coaxial with the rotating rod 5 and extends out of the hopper 1. The screw conveyor 10 can further assist in feeding. The rotating screw conveyor 10 can push the meatballs at the bottom of the hopper 1 to fall smoothly, preventing the meatballs from accumulating and blocking at the bottom of the hopper 1. There is a gap between the screw conveyor 10 and the inner wall of the bottom end of the hopper 1. The gap forms a channel in which the material can flow more freely. When the screw conveyor 10 rotates and pushes the material, the material can be discharged smoothly downward along the gap, and will not accumulate due to the narrow space. When the bottom end of the hopper 1 is blocked, the movement of the screw conveyor 10 can clear the blockage at the bottom end of the hopper 1.

[0038] The working principle of the above embodiment is as follows: the upper end of the rotating rod 5 has two connection methods. When in use, the user can install a coupling on the upper end of the rotating rod 5 and connect it to an external motor, or manually rotate the rotating rod 5.

[0039] When adjusting the feed rate, the user rotates the threaded cylinder 4, causing the threaded cylinder 4 to drive the block 2 to rise vertically, creating an annular gap between the threaded cylinder 4 and the inner wall of the hopper 1 that allows a single meatball to pass through. At the same time, the sliding frame 806 can slide within the chute 805. Subsequently, the user pours the meatball into the hopper 1. The meatball that enters the hopper 1 will pass through the gap along the block 2 and be discharged from the bottom of the hopper 1.

[0040] When meatballs are stuck together in the annular gap, the user can rotate the rotating rod 5 or use an external motor to drive the rotating rod 5 through a coupling. During the rotation of the rotating rod 5, the sliding frame 806 can rotate, which in turn drives the limiting plate 804 to rotate synchronously. This causes the rotating ring 801 to rotate on the inner wall of the block 2. During the rotation of the rotating ring 801, multiple top blocks 802 on its circumferential surface can contact the adjacent insert rods 803 in sequence and push the insert rods 803 to slide. During the sliding process, the insert rods 803 can drive the cutting block 7 to extend out, thereby cutting the meatball stuck in the annular gap. This allows the meatball to pass through the annular gap and be discharged through the bottom of the hopper 1. During the rotation of the rotating rod 5, the auger 10 can also be driven to move, so that the auger 10 can clear the bottom of the hopper 1 during the rotation process and prevent the bottom of the hopper 1 from becoming blocked.
