Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to an automated production equipment and method for knife-cut noodles. Background Technology

[0002] The factory's automated noodle production line integrates multiple processes such as flour mixing, kneading, pressing, and cutting, creating a fully automated production system from raw materials to finished products. In the noodle extrusion and shaping stage, the noodle machine plays a crucial role, efficiently extruding and shaping noodles to consistently produce fresh noodles of uniform thickness and reliable quality. Thanks to its modular design, the noodle machine can flexibly produce noodle products of various shapes by quickly changing the forming roller assembly.

[0003] For knife-cut noodles, a specialty noodle dish, the production line is equipped with specially designed forming rollers to accurately reproduce its iconic "thick in the middle and thin at the edges" shape. However, as market demands for texture become increasingly diverse, the thickness of knife-cut noodles needs to cover different specifications ranging from 1.5 mm to 3 mm. Furthermore, knife-cut noodles exist in two forms: one is the classic shape with a thicker middle and thinner edges on both sides, and the other is a special design with a thicker middle and thinner edges on one side and a flat surface on the other. These factors combined lead to frequent mold changes during production, affecting efficiency. In addition, because the extruded noodles have a sticky surface and small spacing, sticking occurs frequently, negatively impacting product quality. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art by providing an automated production equipment and method for knife-cut surfaces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automated production equipment for knife-cut noodles includes a noodle machine body. The noodle machine body is provided with a dough hopper, a dough pressing roller assembly, a forming cutter roller assembly, and a powdering assembly in sequence along the material conveying direction. The dough pressing roller assembly is located below the dough hopper and includes an active dough pressing roller and a driven dough pressing roller that mesh with each other. The forming cutter roller assembly is located below the dough pressing roller assembly and includes a cutter holder fixedly installed on the noodle machine body, and an active cutter roller and a driven cutter roller that are rotatably installed on the cutter holder. Both the active and driven cutter rollers are provided with several forming parts. Each forming part consists of a fixed ring, an adjusting unit, and a shaping layer. The fixed ring is an annular structure and is fitted onto the active and driven cutter rollers. Two parallel annular plates are fixedly connected to the outer circumference of the fixed ring. A shaping layer is provided between the two annular plates. The shaping layer and the annular plates are fixedly connected to form a sealed cavity. The adjusting unit is provided in the cavity and is used to adjust the surface shape of the shaping layer. A guide panel is inclinedly arranged below the forming cutter roller assembly, and the powder-sprinkling assembly is correspondingly arranged above the guide panel to sprinkle flour onto the surface of the noodles during conveying to prevent them from sticking.

[0006] As a further aspect of the present invention: the molded part includes a first molded part and a second molded part with the same structure; Both the active and driven cutter rollers have a number of first and second forming parts arranged alternately, and adjacent forming parts are closely fitted together. The positions of the first forming parts on the active cutter roller correspond to the positions of the second forming parts on the driven cutter roller, and the positions of the second forming parts on the active cutter roller correspond to the positions of the first forming parts on the driven cutter roller.

[0007] As a further aspect of the present invention: multiple adjustment units are provided, arranged in a ring array with the central axis of the fixed ring as the array center; The adjustment unit includes a slide rod, a sliding block, a connecting member, and an adjustment plate. The two ends of the slide rod are fixedly mounted on the outer surface of the fixed ring via end blocks. The adjustment plate is provided with a sliding groove. A connecting member is rotatably mounted on each of the two end blocks. One end of the connecting member is rotatably connected to the end block, and the other end is slidably mounted in the sliding groove. A support rod is provided on the connecting member. One end of the support rod is rotatably connected to the connecting member, and the other end is rotatably connected to the sliding block. The sliding block is slidably sleeved on the slide rod, and an electromagnet is provided on the sliding block. A spring is provided between the two sliding blocks. The top of the adjustment plate has a groove, and an elastic rubber strip is fixedly installed in the groove. The top of the elastic rubber strip is attached to the inner surface of the shaping layer and is fixedly connected to the shaping layer.

[0008] As a further aspect of the present invention: the elastic strip includes a fixed section in the middle and movable sections on both sides, the fixed section is fixed in the groove, and the ends of the movable sections are fixed on the annular piece; The shaping layer is made of elastic rubber material and is in the shape of an annular strip. The two sides of the shaping layer are fixedly connected to two annular pieces, and the outer sides of the two annular pieces are flush with the two end faces of the fixing ring.

[0009] As a further aspect of the present invention: the outer diameter of the annular piece of the first forming part is not less than the center distance between the active cutter roller and the driven cutter roller.

[0010] As a further embodiment of the present invention: the powder-sprinkling component includes a storage box and a vibrating bottom cover. The storage box is fixedly installed on the main body of the noodle machine and has a connecting groove at the bottom. The vibrating bottom cover is movably installed below the connecting groove for opening and closing the connecting groove. An electric telescopic rod is provided in the connecting groove, and the telescopic end of the electric telescopic rod is connected to the vibrating bottom cover. The vibrating base is provided with a powder-spreading trough plate on the side facing the guide panel, and a through hole is provided on the vibrating base to communicate with the powder-spreading trough plate.

[0011] As a further embodiment of the present invention: the bottom of the connecting groove is in contact with the vibration base, and the vibration base is surrounded by a barrier, the inner wall of the barrier being sized to match the outer wall of the connecting groove. The enclosure is equipped with several air nozzles on the side facing the powder-spreading trough, which are used to blow the flour on the powder-spreading trough onto the guide panel.

[0012] As a further aspect of the present invention: the top of the storage box is provided with a top cover, and the top cover is rotatably hinged to the storage box.

[0013] A method of using an automated knife-cut noodle production equipment, comprising the following steps: S1: By controlling the direction and magnitude of the current in the electromagnets of the sliding blocks in each adjustment unit, the two sliding blocks are driven to move in opposite directions along the slide rod. The movement of the sliding blocks drives the adjustment plate to produce a vertical displacement through the linkage. The displacement of the adjustment plate causes the fixed section of the elastic rubber strip fixed to it to bulge or dent, and at the same time drives the movable section to bend accordingly. The deformation of the elastic rubber strip is transmitted to the molding layer fixed to it, thereby realizing the adjustment of the surface shape of the molding layer. S2: If it is necessary to produce a bladed surface that is thick in the middle and thin on both sides, adjust the shaping layer of all the first forming parts on the active and driven blade rollers to a preset irregular cross-section that is thick in the middle and thin on both sides, and keep the shaping layer of all the second forming parts in a flat initial state. S3: If it is necessary to produce a bladed surface that is thick in the middle and thin at both sides, then the shaping layers of all the first and second forming parts on the active and driven blade rollers should be adjusted to be irregular cross-sections that are thick in the middle and thin at both sides. S4: The prepared dough is put into the dough hopper. The dough is rolled into a dough strip of uniform thickness by the active and driven dough rollers of the dough roller assembly. The dough strip then enters the forming cutter roller assembly. Under the squeezing action of the active and driven cutter rollers, it is shaped by the forming part to form a cut surface that conforms to the set shape. S5: The shaped knife-cut surface slides down along the inclined guide plate. The electric telescopic rod of the powder-spreading component reciprocates at a set frequency. When the electric telescopic rod extends, it drives the vibrating bottom cover to move down, so that the flour in the storage box falls into the powder-spreading tray through the through hole. When the electric telescopic rod retracts, the vibrating bottom cover resets, blocking the flour from falling, and completing one quantitative flour dispensing process. S6: While the vibrating base is resetting, the air nozzle is activated to blow the flour on the powder-spreading tray onto the surface of the knife-cut noodles on the guide panel, forming an anti-sticking powder layer on the noodle surface to prevent the noodles from sticking together.

[0014] Compared with existing technologies, the advantages of this invention are: 1. The molded part is equipped with an adjustable shaping layer. The adjustment unit drives the elastic rubber strip to deform, thereby adjusting the surface shape of the shaping layer in real time. Different thicknesses and shapes of cut surfaces can be produced without replacing the forming cutter roller assembly. This solves the problem of low production efficiency caused by frequent replacement of cutter roller assembly in the existing technology, and significantly improves production flexibility and efficiency.

[0015] 2. A flour-spraying component is installed, which uses an electric telescopic rod to drive the vibrating bottom cover to achieve quantitative flour dispensing. The flour is then blown evenly onto the noodle surface on the guide panel through an air nozzle, forming a uniform anti-sticking powder layer on the noodle surface. This effectively solves the problem of noodles sticking together due to surface stickiness, and significantly improves product quality and consistency. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Reference Figure 1-15 An automated production equipment for knife-cut noodles includes a noodle machine body 100, which serves as the basic frame of the equipment. A noodle hopper 200, a dough pressing roller assembly 300, a forming knife roller assembly 400, and a powder sprinkling assembly 500 are installed sequentially along the material conveying direction. The components cooperate with each other to achieve automated production of knife-cut noodles.

[0020] The dough hopper 200 is bolted to the top of the noodle machine body 100. Its bottom opening faces the dough pressing roller assembly 300 below, which is used to store and feed dough to provide raw materials for subsequent processing. The dough pressing roller assembly 300 is located directly below the dough hopper 200 and is firmly connected to the noodle machine body 100 through two side supports. It includes an active dough pressing roller 310 and a driven dough pressing roller 320 that mesh with each other. The active dough pressing roller 310 is driven by a motor and drives the driven dough pressing roller 320 to rotate synchronously through gear transmission. The axes of the two rollers are parallel and the distance can be adjusted according to production needs. It can evenly roll the dough into a dough strip of appropriate thickness to prepare for knife-cut noodles.

[0021] The forming cutter roller assembly 400 is located below the dough pressing roller assembly 300. The cutter holder 410 is fixed to the noodle machine body 100 by bolts. The active cutter roller 420 and the driven cutter roller 430 are rotatably mounted on the cutter holder 410 by bearings. Multiple forming components 440 are closely arranged on the outer circumference of the active cutter roller 420 and the driven cutter roller 430. The forming components are divided into a first forming component 440a and a second forming component 440b with the same structure.

[0022] Reference Figure 4-9 Multiple first forming elements 440a and second forming elements 440b are mounted on the active cutter roller 420, and the first forming elements 440a and second forming elements 440b are arranged alternately, with adjacent first forming elements 440a and second forming elements 440b in close contact. Similarly, multiple first forming elements 440a and second forming elements 440b are also arranged alternately on the driven cutter roller 430. The positions of the first forming elements 440a on the active cutter roller 420 and the second forming elements 440b on the driven cutter roller 430 correspond to the positions of the first forming elements 440a on the driven cutter roller 430.

[0023] Reference Figure 4-12 Both the first molding part 440a and the second molding part 440b are composed of a fixing ring 441, an adjusting unit 442 and a shaping layer 443. The fixing ring 441 is a ring-shaped metal structure, which is fitted on the active cutter roller 420 and the driven cutter roller 430. Two parallel ring plates 444 are welded to the outer circumference of the fixing ring 441. The shaping layer 443 is made of elastic rubber and is in the shape of a ring strip. The two sides are fixed to the ring plates 444 as an integral structure to form a sealed cavity. The adjusting unit 442 is arranged in a ring array in the cavity with the central axis of the fixing ring 441 as the array center. The adjusting unit 442 is fixedly installed on the outer circumference of the fixing ring 441 and is used to adjust the surface shape of the shaping layer 443.

[0024] Each adjustment unit includes a slide rod 4421, a sliding block 4422, a linkage 4423, and an adjustment plate 4424. The two ends of the slide rod 4421 are welded to the outer surface of the fixed ring 441 through end blocks 4425. The sliding block 4422 is sleeved on the slide rod and can slide, and an electromagnet is embedded inside. One end of the linkage 4423 is hinged to the end block 4425, and the other end is slidably installed in the slide groove 4426 of the adjustment plate 4424 through a pin. The middle part of the linkage 4423 is hinged to the sliding block 4422 through a support rod 4427. A spring 4428 is provided between the two sliding blocks 4422.

[0025] A groove 4429 is formed on the top of the adjusting plate 4424. An elastic strip 4430 is bonded inside the groove 4429. The top of the elastic strip 4430 is fixed to the inner surface of the shaping layer 443. The elastic strip 4430 includes a middle fixed section 4431 and two movable sections 4432 on both sides. The fixed section 4431 is bonded and fixed in the groove 4429, and the ends of the movable sections 4432 are bonded to the inner side of the annular piece 444.

[0026] This structural design allows for the control of the direction and magnitude of the current in the electromagnet within the sliding block 4422 (thus generating attraction or repulsion between the two sliding blocks 4422, causing them to move towards or away from each other), driving the sliding block 4422 to move. This movement, via the linkage 4423, causes the adjusting plate 4424 to undergo vertical displacement, which in turn causes the fixed section 4431 of the elastic strip 4430 to bulge or indent, while simultaneously causing the movable section 4432 to bend accordingly. This achieves the adjustment of the surface shape of the shaping layer 443, allowing the surface of the shaping layer 443 to exhibit the desired thickness in the middle and thinness at both sides for the extruded and shaped surface. Different thicknesses and shapes of shaped surfaces can be produced without replacing the forming roller assembly 400, significantly improving production efficiency and flexibility.

[0027] It should be noted that, initially, the fixed section 4431 and the movable section 4432 of the elastic strip 4430 are flush, meaning the surface of the shaping layer 443 is flat. When it is necessary to produce a bladed surface that is thicker in the middle and thinner at the edges, the first forming part 440a on the active blade roller 420 and the driven blade roller 430 can be made to change the shape of the shaping layer 443 into a bent state, while the second forming part 440b remains flat (e.g., ...). Figure 8 , Figure 9 As shown in the figure, the cut surface produced in this state is a cut surface that is thick in the middle and thin at both sides.

[0028] When it is necessary to produce a double-sided bladed surface that is thicker in the middle and thinner at the edges, the first forming part 440a and the second forming part 440b on the driving blade roller 420 and the driven blade roller 430 can all change the shape of the shaping layer 443 to a bent state (e.g., Figure 6 , Figure 7 As shown in the figure, the cut surface produced in this state is a cut surface that is thick in the middle and thin at both sides.

[0029] It should be noted that the outer diameter of the annular piece 444 of the first forming part 440a is not less than the center distance between the driving cutter roller 420 and the driven cutter roller 430. That is to say, the first forming part 440a on the driving cutter roller 420 and the first forming part 440a on the driven cutter roller 430 are in an alternating meshing state (e.g., Figure 7 , Figure 9 As shown, this design is intended to cut the dough strip in an alternating manner using the first forming part 440a during the extrusion forming process, making it into strips of diced surface.

[0030] Reference Figure 1-15 A guide panel 600 is inclinedly arranged below the forming roller assembly 400. The powder-sprinkling assembly 500 is correspondingly installed above the guide panel 600 and connected to the noodle machine body 100 through a bracket. The powder-sprinkling assembly 500 includes a storage box 510 and a vibrating bottom cover 520. The top of the storage box 510 is fitted with a top cover 512 via a hinge, and a connecting groove 511 is opened at the bottom. The bottom edge of the connecting groove 511 contacts and engages with the top of the vibrating bottom cover 520. The vibrating bottom cover 520 is inverted U-shaped, with its top opening connecting with the connecting groove 511. A surrounding barrier 523 is provided around the perimeter, and the inner wall of the barrier 523 is fitted with a gap to the outer wall of the connecting groove 511 to prevent flour leakage. A powder-sprinkling trough plate 521 is fixedly installed on the side of the vibrating bottom cover facing the guide panel 600. A through hole 522 is opened on the vibrating bottom cover 520 to communicate with the powder-sprinkling trough plate 521.

[0031] An electric telescopic rod 530 is fixedly installed inside the connecting trough 511. The telescopic end of the electric telescopic rod 530 is connected to the center of the top of the vibrating base 520. Multiple air nozzles 524 are evenly arranged on the side of the enclosure 523 facing the powder-spreading trough plate 521. The air nozzles 524 are connected to an external air source through air pipes. The electric telescopic rod 530 drives the vibrating base 520 to move up and down reciprocally. When the electric telescopic rod 530 extends, it drives the vibrating base 520 to move down, so that the flour in the storage box 510 falls into the powder-spreading trough plate 521 through the through hole 522. When the electric telescopic rod 530 retracts, the vibrating base 520 resets, blocking the flour from falling, and completing one quantitative flour dispensing process. In addition, the extension and retraction of the electric telescopic rod 530 can also shake and clear the flour in the storage box 510, even out the flour accumulation, and promote the flow of flour. This shaking can also effectively prevent the flour from clogging the through hole 522, ensuring the continuity of flour delivery.

[0032] The jet nozzle 524 evenly blows the flour on the powder-spraying tray 521 onto the noodle surface on the guide panel 600, effectively preventing the noodles from sticking together and improving product quality.

[0033] It should be noted that the powder spreading tray 521 may not need to be equipped with an air nozzle 524. As long as a hole is opened on the powder spreading tray 521 or a screen is installed, the reciprocating vibration of the vibrating base 520 can be used to spread the flour on the powder spreading tray 521 to the guide panel 600.

[0034] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0035] A method of using an automated knife-cut noodle production equipment, comprising the following steps: S1: By controlling the direction and magnitude of the current in the electromagnets of the sliding blocks 4422 in each adjustment unit 442, the two sliding blocks 4422 are driven to move in opposite directions along the slide rod 4421. The movement of the sliding blocks 4422 drives the adjustment plate 4424 to produce a vertical displacement through the linkage 4423. The displacement of the adjustment plate 4424 causes the fixed section 4431 of the elastic rubber strip 4430 fixed to it to bulge or dent, and at the same time drives the movable section 4432 to bend accordingly. The deformation of the elastic rubber strip 4430 is transmitted to the shaping layer 443 fixed to it, thereby realizing the adjustment of the surface shape of the shaping layer 443. S2: If it is necessary to produce a bladed surface that is thick in the middle and thin on both sides, the shaping layer 443 of all the first forming parts 440a on the active blade roller 420 and the driven blade roller 430 is adjusted to a preset irregular cross section that is thick in the middle and thin on both sides, while keeping the shaping layer 443 of all the second forming parts 440b in a flat initial state. S3: If it is necessary to produce a bladed surface that is thick in the middle and thin at both sides, then the shaping layer 443 of all the first forming parts 440a and the second forming parts 440b on the active blade roller 420 and the driven blade roller 430 should be adjusted to be an irregular cross-section that is thick in the middle and thin at both sides. S4: The prepared dough is placed into the dough hopper 200. The dough is rolled into a uniform thickness dough strip by the active dough roller 310 and the driven dough roller 320 of the dough roller assembly 300. The dough strip then enters the forming cutter roller assembly 400. Under the squeezing action of the active cutter roller 420 and the driven cutter roller 430, it is shaped by the forming part 440 to form a cut surface that conforms to the set shape. S5: The shaped knife-cut surface slides down the inclined guide plate 600. The electric telescopic rod 530 of the powder-spreading component 500 reciprocates at a set frequency. When the electric telescopic rod 530 extends, it drives the vibrating bottom cover 520 to move down, so that the flour in the storage box 510 falls into the powder-spreading tray plate 521 through the through hole 522. When the electric telescopic rod 530 retracts, the vibrating bottom cover 520 resets, blocking the flour from falling, and completing a quantitative flour dispensing process. S6: While the vibrating base 520 is resetting, the jet nozzle 524 is activated to blow the flour on the powder-sprinkling tray 521 onto the surface of the knife-cut noodles on the guide panel 600, forming an anti-sticking powder layer on the noodle surface to prevent the noodles from sticking together.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

9. A method of using an automated knife-cut noodle production equipment, comprising using the automated knife-cut noodle production equipment as described in claim 8, characterized in that, Includes the following steps: S1: By controlling the direction and magnitude of the current of the electromagnet in the sliding block (4422) of each adjustment unit (442), the two sliding blocks (4422) are driven to move in opposite directions along the slide rod (4421). The movement of the sliding block (4422) drives the adjustment plate (4424) to produce a vertical displacement through the linkage (4423). The displacement of the adjustment plate (4424) causes the fixed section (4431) of the elastic rubber strip (4430) fixed to it to bulge or dent, and at the same time drives the movable section (4432) to bend accordingly. The deformation of the elastic rubber strip (4430) is transmitted to the shaping layer (443) fixed to it, thereby realizing the adjustment of the surface shape of the shaping layer (443). S2: If it is necessary to produce a bladed surface with a thick middle and thin sides on one side, the shaping layer (443) of all the first forming parts (440a) on the active blade roller (420) and the driven blade roller (430) is adjusted to a preset irregular cross section with a thick middle and thin sides, while keeping the shaping layer (443) of all the second forming parts (440b) in a flat initial state. S3: If it is necessary to produce a bladed surface that is thick in the middle and thin on both sides, the shaping layer (443) of all the first forming parts (440a) and the second forming parts (440b) on the active blade roller (420) and the driven blade roller (430) should be adjusted to be an irregular cross-section that is thick in the middle and thin on both sides. S4: The prepared dough is placed into the dough hopper (200). The dough is rolled into a uniform thickness strip by the active dough roller (310) and the driven dough roller (320) of the dough roller assembly (300). The strip then enters the forming cutter roller assembly (400). Under the squeezing action of the active cutter roller (420) and the driven cutter roller (430), it is shaped by the forming part (440) to form a cut surface that conforms to the set shape. S5: The shaped knife-cut surface slides down along the inclined guide plate (600), and the electric telescopic rod (530) of the powder-spreading component (500) reciprocates at a set frequency. When the electric telescopic rod (530) extends, it drives the vibrating bottom cover (520) to move down, so that the flour in the storage box (510) falls into the powder-spreading tray plate (521) through the through hole (522). When the electric telescopic rod (530) retracts, the vibrating bottom cover (520) resets, blocking the flour from falling, and completing a quantitative flour dispensing process. S6: While the vibrating base (520) is reset, the jet nozzle (524) is activated to blow the flour on the powder-sprinkling tray (521) onto the surface of the knife-cut noodles on the guide panel (600), forming an anti-sticking powder layer on the noodle surface to prevent the noodles from sticking together.
