Description

Technical Field

[0001] This utility model belongs to the field of noodle cutting technology, specifically relating to a bulk noodle cutting device. Background Technology

[0002] Noodles are a common food. Originating in China, they have a history of being made and eaten for over four thousand years. In the Yellow River basin and areas further north, they are a staple food. They are made by grinding flour from grains or beans with water into dough, then pressing, rolling, or stretching it into sheets before cutting or pressing it again. Alternatively, they can be shaped into strips using techniques such as rubbing, pulling, and pinching. As times changed, handmade noodles could no longer meet people's needs, leading to the development of machines that can automatically cut noodles.

[0003] A search revealed that utility model CN217609249U discloses a cutting and slitting device for noodle production. This device solves the problem that current noodle production processes typically involve manual cutting by workers, resulting in inconsistent noodle lengths and significantly reduced cutting efficiency. The device includes a support plate with a frame connected to one side of its upper end and movable components connected to both sides of the upper end. In this utility model, noodles are placed on a conveyor belt. A first motor drives a rotating roller, causing the conveyor belt to move the noodles to one side. An electric telescopic rod drives a cutting blade to separate the noodles, reducing the workload of workers. A second motor drives a cam, causing a second sliding rod to slide inside a through-hole. A buffer spring provides cushioning, and a sieve box sieves, ensuring that flour is evenly distributed between the noodles and the upper part of the conveyor belt, preventing the noodles from sticking together.

[0004] However, when the sieve box is sifting, it not only spills flour onto the noodles and the conveyor belt, but also causes some flour to suspend in the air and eventually be absorbed and accumulated in parts such as the bolts for mounting the blades. If not cleaned in time, the accumulated flour will mold, which can easily cause food safety problems. Summary of the Invention

[0005] To address the problem of flour adsorption and accumulation at the blade joints when flour is poured onto the conveyor belt in existing noodle slitting machines, this invention proposes a bulk noodle slitting machine to solve the aforementioned problem.

[0006] A bulk noodle cutting device includes a workbench, on which a dust cover and a conveying mechanism for conveying noodles are provided. The two ends of the conveying mechanism are respectively facing the inlet and outlet of the dust cover, and a cutting mechanism is provided above the conveying mechanism.

[0007] Furthermore, the slitting mechanism includes a telescopic electric cylinder, the output end of which is fixedly connected to a mounting plate, and the mounting plate is detachably connected to at least one slitting blade. Flour sieve boxes are provided on both sides of the slitting mechanism.

[0008] Furthermore, the mounting plate includes a mounting plate body, which includes a first plate-shaped portion and a second plate-shaped portion protruding from the surface of the first plate-shaped portion. The first plate-shaped portion and the second plate-shaped portion are fixedly connected and arranged in a stepped manner. An electromagnet is provided inside the mounting plate body, and the working surface of the electromagnet is in close contact with the top surface of the slitting blade.

[0009] Furthermore, at least one positioning groove is provided on the surface of the lower half of the first plate-shaped portion near the slitting blade, and the positioning groove is arranged parallel to the slitting blade.

[0010] Furthermore, the slitting blade includes a blade body, and a permanent magnet layer is provided at the top of the blade body, the permanent magnet layer being in close contact with the working surface of the electromagnet.

[0011] Furthermore, by using an electromagnet to attract and fix the permanent magnet in close contact, no additional bolts are needed, allowing for a smooth transition at the connection between the slitting blade and the mounting plate, forming a flat surface without protrusions. This avoids food safety issues caused by flour adhering to protrusions for a long time and causing mold. It also makes cleaning easier.

[0012] Furthermore, the slitting blade is fixed by using an electromagnet and a permanent magnet. When replacing it, simply turn off the power to the equipment and then remove the slitting blade along the positioning groove, making replacement convenient.

[0013] Furthermore, the cross-sectional shape of the positioning groove is rectangular, rhomboid, arc-shaped, or trapezoidal.

[0014] Furthermore, when the cross-sectional shape of the positioning groove is rectangular, the cross-sectional shape of the positioning block is the same as that of the positioning groove. During installation, the positioning block on the surface of the slitting blade is aligned with the end of the positioning groove on the surface of the mounting plate, so that the positioning block slides in the positioning groove to complete the installation. When the machine is not started, the fixing groove limits the fixing block to prevent the slitting blade from falling off. However, when using slitting blades of different lengths, some fixing grooves are not blocked by fixing blocks. The rectangular cross-section can prevent some flour from entering the groove and is relatively easy to clean. It is suitable for slitting blades of most materials.

[0015] Furthermore, when the cross-sectional shape of the positioning groove is rhomboid, the cross-sectional shape of the positioning block is the same as that of the positioning groove. If the slitting blade is heavy, the cooperation between the rhomboid positioning groove and the positioning block may not prevent the slitting blade from moving downwards. After power failure, the slitting blade may fall under gravity. However, the rhomboid positioning groove tilts the inner surface of the positioning groove, making it less likely for flour to accumulate. When the slitting blade is made of a lighter material such as plastic, a rhomboid positioning groove can be used in conjunction with the positioning block.

[0016] Furthermore, when the cross-sectional shape of the positioning groove is trapezoidal, the cross-sectional shape of the positioning block is the same as that of the positioning groove, and the cutting blade can be firmly fixed on the positioning plate. However, the trapezoidal cross-section causes the interior of the positioning groove to form an inclined surface from the outside to the inside, which easily accumulates flour and is difficult to clean.

[0017] Furthermore, a positioning block is provided on the side of the blade body near the mounting plate. The positioning block is elongated and slides along the positioning groove. The cross-sectional shape of the positioning block corresponds to the cross-sectional shape of the positioning groove.

[0018] Furthermore, the flour sieve box includes a rotary motor, the output end of which extends into the flour sieve box and is connected to a rotating plate. A sieve plate is provided at the bottom of the flour sieve box, and a feeding port is provided on the surface of the flour sieve box.

[0019] Furthermore, the rotating plate is a disc, and multiple elongated protrusions are provided on the upper and lower surfaces of the rotating plate along the circumferential direction. The elongated protrusions are provided with through grooves that penetrate the rotating plate.

[0020] Furthermore, when the rotary motor starts, it drives the rotating plate to rotate, causing the long strip-shaped protrusions to continuously stir the flour. The flour enters the surface of the sieve plate below through the through-holes on the surface of the sieve plate. Some of the flour passes directly through the through-holes on the surface of the sieve plate and is sprinkled onto the noodles. Some of the flour falls onto the surface of the sieve plate and is finally pushed by the long strip-shaped protrusions on the lower surface of the rotating plate towards the through-holes on the surface of the sieve plate and sprinkled onto the noodles on the conveyor belt.

[0021] Furthermore, the sieve plate has multiple through holes evenly distributed on its surface, and the elongated protrusions on the lower surface of the rotating plate are in contact with the upper surface of the sieve plate.

[0022] Furthermore, the transmission mechanism includes a drive roller and a conveyor belt wound around the drive roller. The surface of the conveyor belt is provided with protrusions perpendicular to the transport direction, and the protrusions are elongated.

[0023] Furthermore, protrusions are provided on the surface of the conveyor belt. When the slitting knife cuts, if it comes into contact with a protrusion, it will use the protrusion as support to cut the noodles. If it is between two protrusions, it will use the cavity formed between the two protrusions and the noodles to insert into the cavity and cut the noodles.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The fixing method that combines electromagnets and permanent magnets replaces the traditional bolt connection, achieving a seamless and smooth transition between the blade and the mounting plate, completely eliminating protruding structures, avoiding the risk of flour accumulating and molding at the connection point, simplifying the cleaning process, and improving blade replacement efficiency.

[0026] 2. Hierarchical Adaptation Design of Positioning Grooves

[0027] The design incorporates three positioning groove cross-sections—rectangular, rhomboid, and trapezoidal—to accommodate blades of different materials and weights.

[0028] Rectangular groove: Right angles prevent powder from seeping in, compatible with regular metal blades;

[0029] Diamond-shaped groove: slanted surface for self-cleaning, suitable for lightweight plastic blades;

[0030] Trapezoidal groove: Wedge-shaped secure locking, specifically designed for heavy-duty industrial blades, further enhancing equipment compatibility.

[0031] 3. Dynamic powder sieving and uniform powder spreading system

[0032] The flour sifter box uses a rotary motor to drive a rotating plate with grooves (200-500rpm), which, together with a double-layer sieve plate, achieves two-stage sifting. The rotating plate grooves provide initial filtration, while the sieve plate further refines the powder, improving powder uniformity. The protrusions on the rotating plate rub against the sieve plate to prevent clogging, while also increasing the utilization rate of flour. The rotation speed is adjustable to accommodate different cutting speeds.

[0033] 4. Conveyor belt slitting collaborative structure

[0034] Vertical protrusions are set on the surface of the conveyor belt to form cutting support points and tension shear zones:

[0035] Raised contact: rigid support for cutting thick noodle blocks; cavity cutting: flexible shearing using noodle tension; making the equipment compatible with various noodle specifications and shortening product changeover time. Attached Figure Description

[0061] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0062] The application principle of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0063] like Figure 1-6 , Figure 10-11 As shown; a bulk noodle cutting device, a workbench 1, on which a dust cover 3 and a conveying mechanism for conveying noodles are provided, the two ends of the conveying mechanism are respectively facing the inlet and outlet of the dust cover 3, and a cutting mechanism is provided above the conveying mechanism.

[0064] The slitting mechanism includes a telescopic electric cylinder 9, the output end of which is fixedly connected to a mounting plate 10. At least one slitting blade 11 is detachably connected to the mounting plate 10, and flour sieve boxes 4 are provided on both sides of the slitting mechanism.

[0065] The mounting plate 10 includes a mounting plate body 1001, which includes a first plate-shaped portion and a second plate-shaped portion protruding from the surface of the first plate-shaped portion. The first plate-shaped portion and the second plate-shaped portion are fixedly connected and arranged in a stepped manner. An electromagnet 1002 is provided inside the mounting plate body 1001, and the working surface of the electromagnet 1002 is in close contact with the top surface of the slitting blade 11.

[0066] At least one positioning groove 1003 is provided on the surface of the lower half of the first plate-shaped portion near the slitting blade 11, and the positioning groove 1003 is arranged parallel to the slitting blade 11.

[0067] The slitting blade 11 includes a blade body 1102, and a permanent magnet layer 1101 is provided at the top of the blade body 1102. The permanent magnet layer 1101 is in close contact with the working surface of the electromagnet 1002.

[0068] The permanent magnet is attracted by an electromagnet and fixed in close contact, eliminating the need for additional bolts. This allows for a smooth transition at the connection between the slitting blade 11 and the mounting plate 10, forming a flat surface without protrusions. This avoids food safety issues caused by flour adhering to protrusions for a long time and causing mold. It also makes cleaning easier.

[0069] The slitting blade 11 is fixed by an electromagnet 1002 and a permanent magnet. When replacing it, simply turn off the power to the equipment and then remove the slitting blade 11 along the positioning groove 1003, making replacement convenient.

[0070] A positioning block 1103 is provided on the side of the blade body 1102 near the mounting plate 1001. The positioning block 1103 is elongated and slides along the positioning groove 1003. The cross-sectional shape of the positioning block 1103 corresponds to the cross-sectional shape of the positioning groove 1003.

[0071] The flour sieve box 4 includes a rotary motor 7, the output end of which extends into the flour sieve box 4. The output end of the rotary motor 7 is connected to a rotating plate 5. A sieve plate 6 is provided at the bottom of the flour sieve box 4, and a feeding port 8 is provided on the surface of the flour sieve box 4.

[0072] The rotating plate 5 is a disc. Multiple elongated protrusions are arranged on the upper and lower surfaces of the rotating plate 5 along the circumferential direction. Through grooves are opened on the surface of the elongated protrusions, and the through grooves penetrate the rotating plate 5.

[0073] When the rotary motor 7 starts, it drives the rotating plate 5 to rotate, causing the long strip-shaped protrusions to continuously stir the flour. The flour enters the surface of the sieve plate 6 below through the through-holes on the surface of the sieve plate 6. Some flour passes directly through the through-holes on the surface of the sieve plate 6 and is sprinkled onto the noodles. Some flour falls onto the surface of the sieve plate 6 and is finally pushed by the long strip-shaped protrusions on the lower surface of the rotating plate 5 into the through-holes on the surface of the sieve plate 6 and sprinkled onto the noodles on the conveyor belt 12.

[0074] The sieve plate 6 has multiple through holes evenly distributed on its surface, and the elongated protrusions on the lower surface of the rotating plate 5 are in contact with the upper surface of the sieve plate 6.

[0075] The transmission mechanism includes a transmission roller 2 and a conveyor belt 12 wound on the transmission roller 2. The surface of the conveyor belt 12 is provided with vertical protrusions 1201 perpendicular to the transport direction. The vertical protrusions 1201 are elongated.

[0076] Vertical protrusions 1201 are provided on the surface of the conveyor belt 12. When the slitting knife cuts, if it comes into contact with the vertical protrusions 1201, it will cut the noodles with the vertical protrusions 1201 as support. If it is between two vertical protrusions 1201, it will insert into the cavity formed between the two vertical protrusions 1201 and the noodles to cut the noodles. Example

[0077] like Figure 7 As shown, based on Embodiment 1, when the cross-sectional shape of the positioning groove 1003 is rectangular, the cross-sectional shape of the positioning block 1103 is the same as that of the positioning groove 1003. During installation, the positioning block 1103 on the surface of the slitting blade 11 is aligned with the end of the positioning groove 1003 on the surface of the mounting plate 10, so that the positioning block 1103 slides in the positioning groove 1003 to complete the installation. When the machine is not started, the fixing groove limits the fixing block to prevent the slitting blade 11 from falling off. However, when using slitting blades 11 of different lengths, some fixing grooves are not blocked by the fixing block. The rectangular cross-section can prevent some flour from entering the groove, and it is relatively easy to clean. It is suitable for slitting blades 11 of most materials. Example

[0078] like Figure 8As shown, based on Embodiment 1, when the cross-sectional shape of the positioning groove 1003 is rhomboid, the cross-sectional shape of the positioning block 1103 is the same as that of the positioning groove 1003. If the weight of the slitting blade 11 is large, the cooperation between the rhomboid positioning groove 1003 and the positioning block 1103 may not be able to prevent the slitting blade 11 from moving downwards. After power failure, the slitting blade 11 may fall under the action of gravity. However, the rhomboid positioning groove 1003 makes the inner surface of the positioning groove 1003 inclined, making it difficult for flour to accumulate. When the material of the slitting blade 11 is a lighter material such as plastic, the rhomboid positioning groove 1003 and the positioning block 1103 can be used for cooperation. Example

[0079] like Figure 9 As shown, based on Embodiment 1, when the cross-sectional shape of the positioning groove 1003 is trapezoidal, the cross-sectional shape of the positioning block 1103 is the same as that of the positioning groove 1003, and the cutting blade 11 can be firmly fixed on the positioning plate. However, the trapezoidal cross-section makes the interior of the positioning groove 1003 form an inclined surface from the outside to the inside, which easily accumulates flour and is not easy to clean.

[0080] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
