Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, specifically relating to an automatic feeding mechanism and a noodle processing machine. Background Technology

[0002] The noodle processing technology includes multiple steps such as dough mixing, dough resting, shaping, and subsequent cutting, weighing, and packaging. Currently, most noodle processing companies develop automated equipment for each step of the process and then connect these devices in series to form a production line. The drawback of this approach is that the independent equipment requires connection via conveyor lines and robotic arms, resulting in high equipment costs, low layout compactness, and large space occupation. Therefore, improvements are needed. Utility Model Content

[0003] This utility model provides an automatic feeding mechanism and a noodle processing machine, which aims to reduce the cost and layout space occupied by noodle processing equipment.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: Firstly, an automatic feeding mechanism is provided, comprising a housing and a mixing and conveying assembly. The housing is disposed on the top wall of the main body of a noodle processing machine and has a mixing chamber, a kneading chamber, and a proofing chamber that are horizontally connected in sequence. A feeding hopper is provided at the top of the mixing chamber, and a discharge pipe is provided at the bottom of the proofing chamber. The discharge pipe is located above the feeding port of the noodle processing machine. The mixing and conveying assembly is rotatably connected to the housing and can slide axially to a first position and a second position. A mixing rod assembly is provided on the part of the mixing and conveying assembly that extends into the mixing chamber, and a spiral blade is provided in the middle of the mixing and conveying assembly. When the mixing and conveying assembly is in the first position, the spiral blade extends entirely into the kneading chamber; when the mixing and conveying assembly is in the second position, a portion of the spiral blade extends into the mixing chamber.

[0005] In conjunction with the first aspect, in one possible implementation, the stirring and conveying assembly includes a rotary drive, a telescopic drive, and a main shaft; the main shaft is rotatably connected to the housing and slides along the housing along its axial direction, and has a stirring rod assembly and a spiral blade; the rotary drive is located on the outer wall of the housing and connected to one end of the main shaft, and the telescopic drive is located on the outer wall of the housing and connected to the other end of the main shaft.

[0006] In some embodiments, a sealing plate is provided on the main shaft, the sealing plate being located between the stirring rod assembly and the spiral blades; the sealing plate is used to block the stirring chamber and the kneading chamber in the first position.

[0007] For example, the first end of the spindle extends out of the housing and is slidably fitted with a connecting sleeve along its axial direction. The connecting sleeve is fixedly fitted with the output end of the rotary drive component.

[0008] For example, the second end of the spindle extends out of the housing and is connected to a drive arm, which extends upward and is fixedly connected to the output end of the telescopic drive component.

[0009] In one possible implementation, the stirring rod assembly includes multiple stirring rods spirally spaced on the main shaft, each stirring rod having an inclined scraper at its end away from the main shaft, the inclined scraper being used to scrape materials toward the direction close to the kneading chamber as the main shaft rotates.

[0010] In some embodiments, the kneading cavity includes a straight cavity section and a conical cavity section. One end of the straight cavity section is connected to the mixing cavity, and the other end is connected to the large-diameter end of the conical cavity section. The small-diameter end of the conical cavity section is connected to the proofing cavity.

[0011] For example, the helical blade includes a straight helical section and a conical helical section respectively corresponding to the straight cavity section and the conical cavity section, and the pitch of the helical blade gradually decreases from one end near the stirring chamber to the other end.

[0012] For example, the side wall of the feed hopper is equipped with a water injection nozzle, which is used to connect to the water supply pipeline.

[0013] The beneficial effects of the automatic feeding mechanism provided by this utility model are as follows: Compared with the prior art, the automatic feeding mechanism of this utility model utilizes the space above the main body of the noodle processing machine to install the housing. When the mixing and conveying assembly is in the first position, flour and water can be added to the mixing chamber through the feeding hopper, and the mixing rod assembly is used to mix the flour and water in the mixing chamber to form loose dough. Then, the mixing and conveying assembly slides axially to the second position, and the part of the spiral blade extending into the mixing chamber can carry the loose dough into the kneading chamber. The spiral blade drives the loose dough to move in the kneading chamber, thereby kneading the loose dough and forming it into a whole dough that enters the proofing chamber. After all the loose dough in the mixing chamber has entered the kneading chamber, the mixing and conveying assembly slides back to the first position, at which point flour and water can be added to the mixing chamber again. The water then initiates the next round of mixing. Simultaneously, the dough, no longer pushed by the spiral blades, enters the proofing chamber and remains stationary, thus completing the proofing process. After proofing, the mixing and conveying assembly slides to the second position, and the next batch of loose dough, already mixed, enters the kneading chamber. After being kneaded by the spiral blades into a single dough ball, it enters the proofing chamber. The previously proofed dough is then pushed into the discharge pipe and falls into the feeding port of the noodle processing machine, thus achieving automatic feeding. This automatic feeding mechanism integrates kneading and proofing functions into the noodle processing machine, eliminating the need for separate kneading and proofing machines, as well as conveyors or robotic arms for dough transfer. This not only reduces the equipment cost of the automatic noodle processing production line but also improves the compactness of the equipment layout and reduces space occupation.

[0014] Secondly, this utility model embodiment also provides a noodle processing machine, including the above-mentioned automatic feeding mechanism.

[0015] The beneficial effects of the noodle processing machine provided by this utility model are as follows: Compared with the prior art, the noodle processing machine of this utility model adopts the above-mentioned automatic feeding mechanism, and therefore has the same beneficial effects as the above-mentioned automatic feeding mechanism, which will not be repeated here.

[0021] Please refer to the following: Figure 1 and Figure 2 The automatic feeding mechanism provided by this utility model will now be described. The automatic feeding mechanism includes a housing 10 and a stirring and conveying assembly 30. The housing 10 is disposed on the top wall of the main body of the noodle processing machine 20 and has a stirring chamber 11, a kneading chamber 12 and a proofing chamber 13 connected horizontally in sequence. The top of the stirring chamber 11 is provided with a feeding hopper 14 and the bottom of the proofing chamber 13 is provided with a discharge pipe 15, which is located above the feeding port 21 of the noodle processing machine 20. The stirring and conveying assembly 30 is rotatably connected to the housing 10 and can slide axially to a first position and a second position. The part of the stirring and conveying assembly 30 that extends into the stirring chamber 11 is provided with a stirring rod assembly 331, and the middle part of the stirring and conveying assembly 30 is provided with a spiral blade 332. When the stirring and conveying assembly 30 is in the first position, the spiral blade 332 extends entirely into the kneading chamber 12, and when the stirring and conveying assembly 30 is in the second position, the spiral blade 332 extends partially into the stirring chamber 11.

[0022] Compared with the prior art, the automatic feeding mechanism provided in this embodiment utilizes the space above the main body of the noodle processing machine 20 to install the housing 10. When the mixing and conveying assembly 30 is in the first position, flour and water can be added to the mixing chamber 11 through the feeding hopper 14. The mixing rod assembly 331 is used to mix the flour and water in the mixing chamber 11 to form loose dough. Then, the mixing and conveying assembly 30 slides axially to the second position. The portion of the spiral blade 332 extending into the mixing chamber 11 can carry the loose dough into the kneading chamber 12. The spiral blade 332 drives the loose dough to move in the kneading chamber 12, thereby kneading the loose dough and forming it into a whole dough that enters the proofing chamber 13. After all the loose dough in the mixing chamber 11 has entered the kneading chamber 12, the mixing and conveying assembly 30 slides back to the first position. At this time, flour and water can be added back to the mixing chamber 11. In the next mixing cycle, the dough enters the proofing chamber 13 and remains stationary, no longer pushed by the spiral blades 332, thus completing the proofing process. After proofing, the mixing and conveying assembly 30 slides to the second position again, and the next batch of loose dough, which has been mixed, enters the kneading chamber 12. After being kneaded by the spiral blades 332, it is formed into a whole dough and then enters the proofing chamber 13. This pushes the dough that has already been proofed into the discharge pipe 15 and into the feeding port 21 of the noodle processing machine 20, thereby realizing automatic feeding of the noodle processing machine 20. By using this automatic feeding mechanism, the dough kneading and proofing functions can be integrated into the noodle processing machine 20, which can eliminate the need for a separate dough kneading machine, proofing machine, and conveyor or robotic arm for dough transfer. This not only reduces the equipment cost of the automatic noodle processing production line, but also improves the compactness of the equipment layout and reduces space occupation.

[0023] As one specific embodiment of the above-mentioned mixing and conveying assembly 30, please refer to Figure 1 The stirring and conveying assembly 30 includes a rotary drive 31, a telescopic drive 32, and a main shaft 33. The main shaft 33 is rotatably connected to the housing 10 and slides along the axial direction of the housing 10. The main shaft 33 has a stirring rod assembly 331 and a spiral blade 332. The rotary drive 31 is located on the outer wall of the housing 10 and connected to one end of the main shaft 33. The telescopic drive 32 is located on the outer wall of the housing 10 and connected to the other end of the main shaft 33.

[0024] The rotary drive 31 can be a motor, pneumatic or hydraulic motor, and the telescopic drive 32 can be an electric push rod, pneumatic or hydraulic telescopic cylinder. The rotary drive 31 drives the main shaft 33 to rotate, thereby realizing the stirring action of the stirring rod assembly 331 in the stirring chamber 11 and the kneading and conveying action of the spiral blade 332 in the kneading chamber 12. The telescopic drive 32 and the rotary drive 31 are placed on the outer walls of the two ends of the housing 10 and do not interfere with each other, resulting in a simple and compact structure.

[0025] In some embodiments, see Figure 1 and Figure 2 The main shaft 33 is equipped with a sealing plate 333, which is located between the stirring rod assembly 331 and the spiral blade 332. The sealing plate 333 is used to block the mixing chamber 11 and the kneading chamber 12 in the first position. By setting the sealing plate 333, the inlet of the kneading chamber 12 can be blocked when the telescopic drive 32 drives the main shaft 33 to slide to the first position, thereby preventing flour and water from entering the kneading chamber 12 when they are being stirred in the mixing chamber 11. This can improve the uniformity of contact between flour and water. When the stirring is completed, the telescopic drive 32 drives the main shaft 33 to slide to the second position. The sealing plate 333 enters the mixing chamber 11 with the movement of the main shaft 33 and opens the inlet of the kneading chamber 12. At this time, the spiral blade 332 extending into the mixing chamber 11 carries the loose dough that has been stirred into the kneading chamber 12. The structure is simple and compact, and the manufacturing cost is low.

[0026] like Figure 1 As shown, the first end of the main shaft 33 extends out of the housing 10 and is slidably fitted with a connecting sleeve 334 along its axial direction. The connecting sleeve 334 is fixedly fitted to the output end of the rotary drive 31. The connecting sleeve 334 and the main shaft 33 can be connected by a sliding key to ensure smooth sliding between the two, thereby improving the stability of the sliding movement of the main shaft 33 between the first and second positions. At the same time, the connecting sleeve 334 can be fitted onto the power output shaft of the rotary drive 31 and fixed by a radially inserted pin, thereby ensuring the stability of the power transmission when the rotary drive 31 drives the connecting sleeve 334 and thus drives the main shaft 33 to rotate.

[0027] It should be noted that, as Figure 1 As shown, the second end of the main shaft 33 extends out of the housing 10 and is connected to a drive arm 335. The drive arm 335 extends upward and is fixedly connected to the output end of the telescopic drive member 32. To save axial space, the telescopic drive member 32 is disposed on the outer top wall of the housing 10. Since there is a radial distance between the telescopic drive member 32 and the main shaft 33, the connection between the two is achieved through the drive arm 335. At the same time, the drive arm 335 and the main shaft 33 should be rotated together, and the relative sliding freedom between the main shaft 33 and the drive arm 335 should be constrained based on a step or retaining ring limit, thereby ensuring the stability of the sliding motion of the main shaft 33 driven by the telescopic drive member 32 between the first position and the second position.

[0028] For some possible implementations, please refer to [link / reference]. Figure 1 The stirring rod assembly 331 includes a plurality of stirring rods 3311 spirally spaced on the main shaft 33. Each stirring rod 3311 is provided with an inclined scraper 3312 at the end away from the main shaft 33. The inclined scraper 3312 is used to scrape and deliver materials toward the direction close to the kneading chamber 12 when the main shaft 33 rotates.

[0029] The stirring rod 3311 can be a slender rod structure, with a slanted scraper 3312 welded to its end. The slanted scraper 3312, with its angled inclination, causes the flour to tumble and move towards the kneading chamber 12 as it rotates with the main shaft 33. This allows the loose dough to gradually gather near the kneading chamber 12 during the stirring process, so that the spiral blade 332, which extends into the stirring chamber 11, carries the loose dough into the kneading chamber 12. Although the loose dough gathers towards the kneading chamber 12 during the stirring process, the sealing plate 333 prevents the loose dough from entering the kneading chamber 12 before it is evenly mixed. Therefore, the slanted scraper 3312 at the end of the stirring rod 3311 not only improves the stirring efficiency but also helps to send all the loose dough in the stirring chamber 11 into the kneading chamber 12 after the stirring is completed, thereby improving the feeding efficiency from the stirring chamber 11 to the kneading chamber 12.

[0030] In some embodiments, the kneading chamber 12 described above adopts, for example... Figure 1 The structure shown is as follows. The kneading chamber 12 includes a straight cavity section 121 and a conical cavity section 122. One end of the straight cavity section 121 is connected to the stirring chamber 11, and the other end is connected to the large-diameter end of the conical cavity section 122. The small-diameter end of the conical cavity section 122 is connected to the proofing chamber 13.

[0031] When the loose dough enters the straight cavity section 121, it is in a loose state. As the spiral blade 332 pushes the loose dough into the conical cavity section 122, the space between the spiral blade 332 and the inner wall of the conical cavity section 122 gradually decreases, causing the loose dough to be gradually squeezed into a whole. Finally, it enters the proofing cavity 13 from the small diameter end of the conical cavity section 122. This can improve the kneading effect of the spiral blade 332 on the dough and improve the quality of the dough.

[0032] It should be noted that, as Figure 1 As shown, based on the above-mentioned structural form adopted by the kneading chamber 12, the spiral blade 332 includes a straight spiral section 3321 and a conical spiral section 3322 respectively provided for the straight cavity section 121 and the conical cavity section 122, and the pitch of the spiral blade 332 gradually decreases from one end near the mixing chamber 11 to the other end. The diameter of the spiral blade 332 adapts to the change of the inner diameter of the kneading chamber 12 to avoid collision and interference between the spiral blade 332 and the inner wall of the kneading chamber 12. On this basis, considering that the loose dough is gradually squeezed into a whole by the kneading and conveying of the spiral blade 332 in the kneading chamber 12, the pitch of the spiral blade 332 gradually decreases with the conveying direction, thereby utilizing the change of space to improve the squeezing effect of the spiral blade 332 on the dough, which helps to improve the quality of the dough.

[0033] In some embodiments, please refer to Figure 1The side wall of the feed hopper 14 is provided with a water spray nozzle 16, which is used to connect to the water supply pipeline. During the process of adding flour to the feed hopper 14, water is sprayed into the feed hopper 14 using the water spray nozzle 16, which can improve the uniformity of contact between flour and water, and is beneficial to improving the uniformity and efficiency of mixing flour and water in the mixing chamber 11.

[0034] Based on the same inventive concept, combined with Figure 1 and Figure 2 It is understood that this application embodiment also provides a noodle processing machine 20, including the above-mentioned automatic feeding mechanism.

[0035] The noodle processing machine 20 provided in this embodiment, compared with the prior art, adopts the above-mentioned automatic feeding mechanism. The housing 10 is installed using the space above the main body of the noodle processing machine 20. When the mixing and conveying assembly 30 is in the first position, flour and water can be added to the mixing chamber 11 through the feeding hopper 14. The mixing rod assembly 331 stirs the flour and water in the mixing chamber 11 to form loose dough. Then, the mixing and conveying assembly 30 slides axially to the second position. The portion of the spiral blade 332 extending into the mixing chamber 11 carries the loose dough into the kneading chamber 12. The spiral blade 332 drives the loose dough to move in the kneading chamber 12, kneading the loose dough and forming it into a whole dough that enters the proofing chamber 13. After all the loose dough in the mixing chamber 11 has entered the kneading chamber 12, the mixing and conveying assembly 30 slides back to the first position. At this time, more flour and water can be added to the mixing chamber 11. Flour and water are added for the next round of mixing. At the same time, the whole dough enters the proofing chamber 13 and is no longer pushed by the spiral blades 332, remaining in a static state to complete the proofing. After proofing, the mixing and conveying component 30 slides to the second position again. The next batch of loose dough that has been mixed enters the kneading chamber 12 and is kneaded by the spiral blades 332 to form a whole dough before entering the proofing chamber 13. This pushes the previously proofed dough into the discharge pipe 15 and into the feeding port 21 of the noodle processing machine 20, thus realizing automatic feeding of the noodle processing machine 20. Using this automatic feeding mechanism, the dough kneading and proofing functions can be integrated into the noodle processing machine 20, eliminating the need for a separate dough kneading machine, proofing machine, and conveyor or robotic arm for dough transfer. This not only reduces the equipment cost of the automatic noodle processing production line but also improves the compactness of the equipment layout and reduces space occupation.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
