Description

Technical Field

[0001] The utility model relates to the field of noodle production equipment technology, and in particular to a noodle rolling and forming machine. Background Technology

[0002] A noodle extrusion machine, a professional piece of equipment for making noodles, dough sheets, and other types of pasta, works by precisely adjusting the distance between two rollers to control the thickness of the noodles. Furthermore, by using different molds, it can produce noodles of various sizes, such as wide and thin noodles. To achieve gradual extrusion of the dough, the machine typically uses multiple two-roller groups, with the gap between the two rollers in each group gradually changing. However, during the extrusion process, the dough is continuously stretched, exposing the gluten inside. Because the newly exposed gluten surface is not coated with flour, it is highly sticky and easily adheres to the rollers, negatively impacting the subsequent extrusion of the dough.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN214385813U, patent name: a noodle rolling machine) is as follows: it includes a worktable, on which multiple sets of fixed shells are provided, and an active roller for rolling noodles is provided inside the fixed shell, and a driven roller is provided below the active roller.

[0004] As can be seen from the implementation plan and its corresponding drawings, this noodle rolling machine relies solely on the active and driven rollers to roll the dough, without taking any measures to prevent the dough from sticking to the rollers. As the usage time increases, a large number of small dough balls will stick to the rollers, which will inevitably affect the subsequent rolling effect. Utility Model Content

[0005] This utility model overcomes the shortcomings of existing technologies and provides a noodle rolling and forming machine, which is equipped with a rolling component, a powdering component, and a turning component. The turning component and the powdering component can perform two powdering operations at different key stages of dough conveying. The turning component is used to turn the dough over so that the powdering component can powder both sides of the dough. This staged and surface-specific powdering method can ensure that the upper and lower surfaces of the dough are evenly coated with flour from all directions. In the subsequent rolling and conveying process, the flour effectively reduces the friction and stickiness between the dough and the equipment surface, so that the dough adheres less to the active and passive rollers, and the active and passive rollers can roll the dough stably for a long time.

[0006] To solve the above-mentioned technical problems, the utility model is implemented through the following technical solution:

[0007] A noodle rolling and forming machine is characterized by comprising rolling components, a turning component between every two rolling components, and a powdering component above the turning component. After the dough is rolled by the rolling components, it is conveyed by the conveying components. In the first stage of conveying, the powdering component applies powder to the upper surface of the dough for the first time. Then, the turning component turns the dough over. After turning, the dough continues to be conveyed by the conveying components for the second stage, at which time the powdering component applies powder to the dough for the second time. The first and second powdering are applied to the two surfaces of the dough, respectively.

[0008] Furthermore, the flipping assembly includes a flipping conveyor belt assembly and a flipping extension component. The flipping conveyor belt assembly is inclined, and a flipping transition gap is maintained between the lower end of the flipping conveyor belt assembly and the upper surface of the conveying assembly.

[0009] The flipping conveyor belt assembly is arranged in parallel with the flipping extension component. The flipping conveyor belt assembly includes several parallel circular belts, and the flipping extension component includes an extension power component and an extension fence plate.

[0010] The circular belt is fitted into the gaps in the extended fence panels.

[0011] Furthermore, when the extended power component retracts, the extended grid plate overlaps with the turning conveyor belt assembly. When the dough is conveyed to the first section of the conveying assembly and approaches the lower end of the turning conveyor belt assembly, the extended grid plate extends under the push of the extended power component and inserts into the belt gap of the conveying assembly. At this time, the turning transition gap is filled by the extended grid plate, and the dough is conveyed to the turning conveyor belt assembly along the extended grid plate.

[0012] When the entire dough is pushed onto the turning conveyor belt assembly, the turning conveyor belt assembly runs in the opposite direction, conveying the dough to the conveyor component. At this time, the extended power component retracts, and the extended grid plate retracts to a position higher than the lower end of the conveyor belt assembly. A turning transition gap appears between the lower end of the turning conveyor belt assembly and the upper surface of the conveyor component. At this time, the downward direction of the dough is opposite to the forward direction of the conveyor component. The upper surface of the dough contacts the conveyor component first, and the dough falls onto the conveyor component to achieve the turning action.

[0013] Furthermore, the calendering assembly includes a calendering base, which is provided with an adjusting slide rail. The adjusting slide rail is slidably connected to a sliding bearing seat, which is connected to a passive roller. The calendering base is rotatably connected to an active roller, and one end of the active roller is connected to a calendering motor.

[0014] Furthermore, a spring is installed inside the adjusting slide, with one end of the spring abutting against the sliding bearing seat. An adjusting linkage roller is installed on the side of the sliding bearing seat away from the spring. The adjusting linkage roller is connected to the adjusting motor, and both ends of the adjusting linkage roller are connected to a worm gear assembly. The worm gear assembly is connected to an adjusting push rod, and one end of the adjusting push rod abuts against the sliding bearing seat.

[0015] Furthermore, a scraper component is provided on one side of both the active roller and the passive roller. The scraper component includes a scraper, and the blade of the scraper is in close contact with the roller surface of the active roller and the passive roller.

[0016] Furthermore, the scraper component includes a scraper member and a shaft angle adjustment member;

[0017] The scraper component includes a scraper shaft, and the scraper is connected to the scraper shaft. When the scraper shaft rotates, it drives the scraper to rotate. The rotation of the scraper is used to adjust the gap between the scraper blade and the roller surfaces of the active roller and the passive roller.

[0018] Furthermore, one end of the scraper shaft is connected to a gear;

[0019] The shaft angle adjustment component includes a shaft adjustment base, and a rack is slidably connected to the shaft adjustment base, with the rack meshing with a gear.

[0020] One end of the rotating shaft adjustment base is threadedly connected to the adjustment screw, and the end of the adjustment screw is rotatably connected to the rack;

[0021] The adjusting screw is threadedly connected to the tightening nut.

[0022] Furthermore, the powder-spraying assembly includes a powder-storing vibration frame, and a powder-storing adjustment plate is slidably connected to the lower end of the powder-storing vibration frame;

[0023] The bottom of the powder storage vibration frame is provided with a first powder outlet hole, the powder storage adjustment plate is provided with a second powder outlet hole, and an adjustment handle is provided on one side of the powder storage adjustment plate.

[0024] Furthermore, the conveying assembly includes a first conveying assembly, a second conveying assembly, a third conveying assembly, a fourth conveying assembly, and a fifth conveying assembly. The first conveying assembly feeds the dough into a first pressing assembly for pressing. The pressed dough is then output through the second conveying assembly. The second conveying assembly and the first half of the third conveying assembly form the first conveying section of the conveying assembly. The second half of the third conveying assembly and the fourth conveying assembly form the second conveying section of the conveying assembly. The fourth conveying assembly feeds the dough into a second pressing assembly for pressing. The pressed dough is then output through the fifth conveying assembly.

[0025] Compared with existing technologies, the advantages of this utility model are:

[0026] The system is equipped with a pressing component, a powdering component, and a turning component. The turning and powdering components can perform two powdering operations at different key stages of dough conveying. The turning component is used to turn the dough over so that the powdering component can powder both sides of the dough. This staged and surface-specific powdering method can ensure that the top and bottom surfaces of the dough are evenly coated with flour from all directions. During the subsequent pressing and conveying process, the flour effectively reduces the friction and stickiness between the dough and the equipment surface. In the pressing stage, the dough can pass through the gap between the active and passive rollers more smoothly, avoiding problems such as uneven pressing and inconsistent noodle thickness caused by dough sticking to the roller surface, thus ensuring the forming quality of the noodles. During the conveying process, it also reduces the situation of dough sticking to the conveyor belt, preventing tearing and jamming of the dough during conveying. This makes the entire production process efficient and stable, greatly improving production efficiency and product quality. Attached Figure Description

[0037] The preferred embodiments of the utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model.

[0038] like Figures 1 to 8 As shown, a noodle rolling forming machine includes a rolling assembly 1, a turning assembly 3 is provided between every two sets of rolling assemblies 1, and a powder spraying assembly 2 is provided above the turning assembly 3. After the dough is rolled by the rolling assembly 1, it is conveyed by the conveying assembly.

[0039] The conveying assembly includes a first conveying assembly 4, a second conveying assembly 5, a third conveying assembly 6, a fourth conveying assembly 7, and a fifth conveying assembly 8. The specific conveying process is as follows: the first conveying assembly 4 feeds the dough into the first pressing assembly 1 for pressing, and the pressed dough is then output through the second conveying assembly 5. The second conveying assembly 5 and the first half of the third conveying assembly 6 together form the first conveying path of the conveying assembly; the second half of the third conveying assembly 6 and the fourth conveying assembly 7 form the second conveying path of the conveying assembly. Then, the fourth conveying assembly 7 feeds the dough into the second pressing assembly 1 for further pressing, and the pressed dough is then output through the fifth conveying assembly 8.

[0040] During the conveying process, when the dough is in the first conveying path, the powdering component 2 will perform an initial powdering operation on the upper surface of the dough. Subsequently, the flipping component 3 will flip the dough over, and the flipped dough will continue to be conveyed in the second conveying path, at which point the powdering component 2 will perform a second powdering operation. In this way, the first and second powdering operations will act on the two surfaces of the dough respectively.

[0041] Therefore, by setting up the powdering component 2 to apply powder twice at different stages of dough conveying, and targeting both surfaces of the dough respectively, it can be ensured that the upper and lower surfaces of the dough are evenly coated with flour, effectively reducing the possibility of the dough sticking to the equipment during pressing and conveying, and ensuring the smooth operation of the production process.

[0042] The flipping assembly 3 includes a flipping conveyor belt assembly 301 and a flipping extension component 302. The flipping conveyor belt assembly 301 is inclined, and a flipping transition gap is reserved between its lower end and the upper surface of the conveying assembly.

[0043] The flipping conveyor belt assembly 301 and the flipping extension component 302 are arranged in parallel. The flipping conveyor belt assembly 301 includes several parallel circular belts, and the flipping extension component 302 includes an extension power component 3021 and an extension fence plate 3022.

[0044] The round belt is fitted into the gap of the extended fence panel 3022.

[0045] When the extension power component 3021 retracts, the extension fence plate 3022 overlaps with the turning conveyor belt assembly 301. When the dough is conveyed to the first section of the conveyor assembly and approaches the lower end of the turning conveyor belt assembly 301, the extension fence plate 3022 extends under the push of the extension power component 3021 and inserts into the belt gap of the conveyor assembly. At this time, the turning transition gap is filled by the extension fence plate 3022, creating a channel for the dough to transition from the conveyor assembly to the turning conveyor belt assembly 301. This allows the dough to be smoothly conveyed along the extension fence plate 3022 onto the turning conveyor belt assembly 301, reducing the chance of the dough getting stuck or falling during the conveying process and improving production efficiency.

[0046] The dough is conveyed along the extension fence 3022 to the turning conveyor belt assembly 301. Through a simple structural combination of the turning conveyor belt assembly 301, the turning extension component 302, etc., the turning function of the dough is realized by the extension and retraction of the extension fence 3022 and the forward and reverse operation of the turning conveyor belt assembly 301. The design is ingenious and easy to manufacture and maintain.

[0047] When the entire dough is pushed onto the turning conveyor belt assembly 301, the turning conveyor belt assembly 301 then runs in the opposite direction, conveying the dough to the conveying component. At this time, the extension power component 3021 retracts, and the extension fence plate 3022 retracts to a position higher than the lower end of the conveyor belt assembly 301. A turning transition gap appears between the lower end of the turning conveyor belt assembly 301 and the upper surface of the conveying component. At this time, the downward direction of the dough is opposite to the forward direction of the conveying component, and the upper surface of the dough contacts the conveying component first. The dough falls onto the conveying component, realizing the turning action. By utilizing the characteristic that the downward direction of the dough is opposite to the forward direction of the conveying component, it is ensured that the upper surface of the dough contacts the conveying component first, which can effectively realize the turning of the dough, ensure the accuracy and stability of the turning action, and improve the quality of dough processing in the noodle production process.

[0048] The round belt is fitted into the gap of the extended fence plate 3022. This design allows the turning component 3 to adapt to dough of different sizes and shapes, and has strong versatility and adaptability to meet diverse production needs.

[0049] The extrusion assembly 1 includes an extrusion base 101, which is provided with an adjustment slide 1011 and an arc-shaped observation window 1012. The arc-shaped observation window 1012 is directly opposite the blade position of the scraper 10413, facilitating observation when adjusting the scraper 10413. The adjustment slide 1011 is slidably connected to a sliding bearing seat 106, which is connected to a passive roller 103. The extrusion base 101 is rotatably connected to an active roller 102. One end of the active roller 102 is connected to an extrusion motor 1021, which provides rotational power to the active roller 102, causing it to rotate and providing basic power for extruding the dough.

[0050] A spring 105 is installed inside the adjusting slide rail 1011. One end of the spring 105 abuts against the sliding bearing seat 106. An adjusting linkage roller 108 is installed on the side of the sliding bearing seat 106 away from the spring 105. The adjusting linkage roller 108 is connected to the adjusting motor 107. Both ends of the adjusting linkage roller 108 are connected to the worm gear assembly 109. The worm gear assembly 109 is connected to the adjusting push rod 1091. One end of the adjusting push rod 1091 abuts against the sliding bearing seat 106.

[0051] During operation, the regulating motor 107 drives the regulating linkage roller 108 to rotate, which in turn drives the two worm gear sets 109 to move. The movement of the worm gear sets 109 causes the regulating push rod 1091 to push the sliding bearing seat 106. By changing the position of the sliding bearing seat 106, the distance between the passive roller 103 and the active roller 102 is adjusted, thereby precisely controlling the degree of pressing of the dough by the passive roller 103 and the active roller 102. In this way, only one regulating motor 107 is needed to simultaneously control the positions of both ends of the passive roller 103, ensuring precise adjustment of the degree of pressing. In addition, the spring 105 and the regulating push rod 1091 cooperate to adjust the position of the sliding bearing seat 106, so that the end of the regulating push rod 1091 only needs to abut against the sliding bearing seat 106, without needing to be connected to the sliding bearing seat 106. This greatly simplifies the connection method between components and effectively reduces the difficulty of assembly and subsequent maintenance.

[0052] Spring 105 plays a buffering and coordinating role during the adjustment process. When the adjusting push rod 1091 pushes the sliding bearing seat 106, spring 105 will compress or extend according to the force applied, assisting in adjusting the position of the sliding bearing seat 106, and at the same time, it can absorb the impact force during the adjustment process to a certain extent.

[0053] The worm gear assembly 109 has a self-locking function, which can maintain the stable position of the driven roller 103 after it is adjusted to a suitable position, avoiding positional changes caused by external forces during the rolling process, and ensuring the stability and reliability of the rolling process. At the same time, the buffering effect of the spring 105 also helps to improve the stability of the entire mechanism.

[0054] A scraper component 104 is provided on one side of both the driving roller 102 and the driven roller 103. The scraper component 104 includes a scraper 10413, the blade of which is in close contact with the roller surfaces of the driving roller 102 and the driven roller 103. The scraper component 104 includes a scraper member 1041 and a shaft angle adjustment member 1042. The scraper member 1041 includes a scraper shaft 10411, and the scraper 10413 is connected to the scraper shaft 10411. When the scraper shaft 10411 rotates, it drives the scraper 10413 to rotate. The rotation of the scraper 10413 is used to adjust the gap between the blade of the scraper 10413 and the roller surfaces of the driving roller 102 and the driven roller 103. One end of the scraper shaft 10411 is connected to the gear 10412; the shaft angle adjustment component 1042 includes a shaft adjustment base 10421, a rack 10422 is slidably connected to the shaft adjustment base 10421, and the rack 10422 is meshed with the gear 10412; one end of the shaft adjustment base 10421 is threadedly connected to the adjustment screw 10423, and the end of the adjustment screw 10423 is rotatably connected to the rack 10422; the adjustment screw 10423 is threadedly connected to the tightening nut 10424.

[0055] When it is necessary to adjust the gap between the blade of the scraper 10413 and the surfaces of the drive roller 102 and the driven roller 103, rotate the adjusting screw 10423. Since the adjusting screw 10423 is threadedly connected to the rotating shaft adjusting base 10421 and its end is rotatably connected to the rack 10422, rotating the adjusting screw 10423 will cause the rack 10422 to slide linearly on the rotating shaft adjusting base 10421. The linear sliding of the rack 10422 will drive the gear 10412 that meshes with it to rotate. Because gear 10412 is installed at one end of scraper shaft 10411, the rotation of gear 10412 will cause scraper shaft 10411 to rotate. The rotation of scraper shaft 10411 will drive the connected scraper 10413 to rotate, thereby changing the gap between the blade of scraper 10413 and the roller surfaces of drive roller 102 and passive roller 103, thus achieving gap adjustment. After adjustment, tighten the top nut 10424 to fix the position of adjusting screw 10423, preventing it from rotating due to vibration or other factors during equipment operation. This ensures the stability of the gap between scraper 10413 and roller surface, preventing the gap of scraper 10413 from changing due to vibration or other factors during equipment operation, and ensuring the stability and reliability of scraper component 104.

[0056] Through the meshing transmission of gear 10412 and rack 10422, the rotational motion of adjusting screw 10423 is converted into the rotation of scraper shaft 10411, which can precisely control the rotation angle of scraper 10413, thereby achieving precise adjustment of the gap between the scraper blade 10413 and the roller surface. This ensures that the scraper can effectively remove the adhering substances on the roller surface while avoiding excessive damage to the roller surface. Therefore, the scraper gap can be adjusted simply by rotating adjusting screw 10423. The operation process is simple and easy to understand, requiring no complicated tools or professional skills, thus reducing the difficulty and labor intensity of the operator.

[0057] The scraper component 104 has a compact overall structure, with tight connections between its components, and occupies little space. This is beneficial for the overall layout and installation of the equipment, and also facilitates the maintenance and repair of the scraper component 104.

[0058] The powder spraying assembly 2 includes a powder storage vibration frame 201, and a powder storage adjustment plate 202 is slidably connected to the lower end of the powder storage vibration frame 201;

[0059] The powder storage vibration frame 201 has a first powder outlet hole 2011 at the bottom, the powder storage adjustment plate 202 has a second powder outlet hole 2021, and the powder storage adjustment plate 202 has an adjustment handle 2022 on one side.

[0060] The powder is stored in a powder storage vibrating frame 201. The vibration of the frame 201 facilitates the flow of the powder. The amount of powder flowing out of the frame 201 is controlled by changing the overlapping area of ​​the first powder outlet 2011 and the second powder outlet 2021. When the overlapping area of ​​the two powder outlets increases, the amount of powder discharged increases; when the overlapping area decreases, the amount of powder discharged decreases. Under the vibration of the powder storage vibrating frame 201, the powder flows out through the overlapping first powder outlet 2011 and second powder outlet 2021, thus achieving the powder spraying operation.

[0061] By changing the overlapping area of ​​the powder outlet holes by sliding the powder storage adjustment plate 202, the amount of powder can be flexibly adjusted according to actual needs, meeting the requirements of different production processes for flour usage, improving the applicability and flexibility of the equipment. The vibration design of the powder storage vibration frame 201 helps the powder flow, prevents the powder from clumping in the powder storage frame or blocking the powder outlet holes, ensures the smooth progress of the powder spraying process, and improves the uniformity and stability of powder spraying.

[0062] The noodle rolling forming machine of this utility model is ingeniously designed with a rolling component 1, a powdering component 2 and a turning component 3. The turning component 3 and the powdering component 2 can perform two powdering operations at different key stages of dough conveying, and these two powdering operations are precisely applied to the two surfaces of the dough, namely the upper surface and the lower surface.

[0063] When the dough first enters the conveying process, the flour-sprinkling component 2 sprinkles flour on the upper surface of the dough. This operation is like putting a "protective coat" on the upper surface of the dough. The evenly applied flour plays a good role in lubrication and isolation during the contact between the dough and the conveying components and the subsequent rolling components. As the dough continues to be conveyed, the turning component 3 turns the dough over so that the previously un-floured lower surface is facing upwards. At this time, the flour-sprinkling component 2 plays its role again, sprinkling flour on the lower surface of the dough a second time, so that the lower surface of the dough is also evenly covered with a layer of flour.

[0064] This phased, surface-specific flour application method ensures that the dough is evenly coated with flour on both the top and bottom surfaces. During subsequent pressing and conveying, the flour effectively reduces friction and stickiness between the dough and the equipment surfaces. In the pressing stage, the dough passes more smoothly through the gap between the active and passive rollers, preventing uneven pressing and inconsistent noodle thickness caused by dough adhering to the roller surfaces, thus ensuring noodle quality. During conveying, it also reduces dough adhesion to the conveyor belt, preventing tearing and jamming, enabling the entire production process to proceed efficiently and stably, significantly improving production efficiency and product quality.

[0065] Finally, it should be noted that the above are merely preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the utility model should be included within the protection scope of the utility model.
