Description

Technical Field

[0001] The present invention relates to the technical field of food production machinery, and more specifically to a double-row noodle merging device. Background Art

[0002] Factory-scale mass production of fine dried noodles involves multiple steps, including kneading, curing, extrusion, forming, screening, drying, and packaging. Modern noodle packaging machines are far more efficient than the forming and drying steps alone. Therefore, during the packaging process, two rows of noodles must be combined into a single row, which is then conveyed to the packaging system via a conveyor. However, existing combining devices are unable to neatly combine the noodles, thus requiring improvement and development. For example, my Chinese patent application 2012200497720 discloses "A Horizontal Automatic Noodle Packaging Machine," with Grant Announcement No. CN202541873U. This noodle packaging machine utilizes electrical integration technology, with a PLC system as the central control for servo and pneumatic devices, ensuring precise coordination of various components. It features a compact structure, simple operation, reliable operation, stable and precise production, and tightly packed noodles. However, due to the lack of a double-row combining device, noodles on two conveyor belts cannot be combined. Summary of the Invention

[0003] The purpose of the present invention is to provide a double-row noodle merging device, which merges two rows of noodles arranged side by side on a conveyor belt into one row, so as to improve the efficiency of transportation and packaging.

[0004] The technical solution adopted by the present invention to solve the technical problem is: The double-row noodle merging device described in the present invention includes a double-row conveyor for conveying double-row noodles, the double-row conveyor is horizontally arranged, and a turnover hopper is provided at the end of the double-row conveyor. The turnover hopper is a bucket-shaped structure formed by a semicircular retaining ring and a flat baffle. The lower end of the turnover hopper is provided with a long strip discharge port arranged perpendicular to the baffle, and a single-row conveyor is provided below the discharge port. A left slide and a right slide are respectively provided in the inner cavity of the turnover hopper on both sides of the discharge port. The upper surfaces of the slide and the right slide are inclined, and the height gradually decreases from the connection point of the baffle to the far end; the outer side surface of the baffle is connected to the end of the double-row conveyor so that the noodles transported by the double-row conveyor can fall into the tipping hopper by relying on the inertia of movement, and an upper guide plate is fixedly installed in the middle position of the baffle for blocking the movement of one end of the noodles entering the tipping hopper, the plate surface of the upper guide plate is parallel to the upper edge line of the baffle, the lower end of the upper guide plate is located on the inner side of the baffle, and the upper end is inclined toward the outer side of the baffle.

[0005] Through this solution, the device can turn the double rows of noodles conveyed side by side by 90 degrees towards each other in the turning hopper and merge them into one row, which can improve the efficiency of conveying and packaging.

[0006] Preferably, the upper guide plate is fixedly connected to the lower guide plate, the plate surface of the lower guide plate is located on the central axis of the double-row conveyor, and the lower end of the lower guide plate is provided with a left-inclined plate and a right-inclined plate that are symmetrically arranged and bent to both sides thereof; the upper guide plate is located above the left-inclined plate and the right-inclined plate.

[0007] Through this solution, after the upper guide plate blocks the inner end of the noodles and slows it down, the left and right inclined plates can slow down the falling speed of the inner end of the noodles, promote the smooth turning of the noodles, and reduce the breakage rate of the noodles.

[0008] Preferably, the lower end of the upper guide plate is provided with a rearward tilting plate inclined toward the retaining ring.

[0009] Through this solution, the resistance applied by the rear tilting plate to the noodles is relatively gentle, which can reduce the breakage rate of the noodles.

[0010] Preferably, the upper end of the retaining ring is provided with an outward-turned retaining ring fold, and the upper end of the baffle is provided with an outward-turned baffle fold, and the baffle fold is arranged horizontally.

[0011] Through this solution, the folded edge of the retaining ring can play a protective role, and the folded edge of the baffle can reduce the gap between the tipping hopper and the double-row conveyor, ensuring that the noodles conveyed by the double-row conveyor can smoothly enter the tipping hopper.

[0012] Preferably, the upper surfaces of the left slide and the right slide are connected to the discharge port via the inclined inner wall of the left slide and the inner wall of the right slide respectively.

[0013] With this solution, the flipped noodles slide along the inner walls of the left and right slides to the discharge port, which can reduce the impact force of the noodles when they slide and reduce the breakage rate of the noodles.

[0014] Preferably, the lower end of the discharge port is connected to a vertical blanking device, and the vertical blanking device is a pipe with a rectangular transverse cross-section that is adapted to the discharge port and a Z-shaped longitudinal cross-section.

[0015] With this solution, the noodles discharged from the discharge port are arranged through multiple sliding and turning actions in the Z-shaped pipe, which is conducive to the neat arrangement of the noodles.

[0016] Due to the adoption of the above structure, the device can merge two rows of noodles conveyed side by side into one row by turning them 90 degrees towards each other in the turning hopper. The breakage rate of noodles is low during the merging process, and the noodles after merging are arranged neatly, which is conducive to improving the efficiency of conveying and packaging.

[0025] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0026] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0027] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0028] like Figure 1As shown, the double-row noodle merging device of the present invention includes a double-row conveyor 1 for conveying double-row noodles. The double-row conveyor 1 is horizontally arranged, with a tipping hopper 2 located at the end of the double-row conveyor 1. A single-row conveyor 4 is located below the tipping hopper 2. During operation, two rows of noodles 3 on the double-row conveyor 1 are placed side by side. As the double-row conveyor 1 operates, the noodles are transported into the tipping hopper 2. There, they merge and fall onto the single-row conveyor 4, where they are rearranged into a single row. Both the double-row conveyor 1 and the single-row conveyor 4 are belt conveyors, driven by motor-driven rollers to transport the noodles along the conveyor belts in a straight line. A first frame 19 and a second frame 49 are located at the lower ends of the double-row conveyor 1 and the single-row conveyor 4, respectively, to facilitate raising the working surface of the conveyor belt on the double-row conveyor 1 to the height of the tipping hopper 2 and positioning the working surface of the conveyor belt on the single-row conveyor 4 below the tipping hopper 2. The belt conveyor is also called a belt conveyor, and its structure and working principle are prior art and will not be described again in detail. In this embodiment, the transmission direction of the single-row conveyor 4 is perpendicular to the transmission direction of the double-row conveyor 1.

[0029] like Figure 2 As shown, the tipping hopper 2 is welded from stainless steel plates. The tipping hopper 2 is a bucket-shaped structure formed by a semicircular retaining ring 21 and a flat baffle 22. The two ends of the retaining ring 21 are welded to the two ends of the baffle 22 to form a semicircular inner cavity structure. The upper end of the retaining ring 21 is provided with an outward-turned retaining ring fold 211, and the upper end of the baffle 22 is provided with an outward-turned baffle fold 221. The baffle fold 221 is arranged horizontally. The baffle fold 221 is used to fill the gap between the tipping hopper 2 and the double-row conveyor 1 and to receive the noodles 3 conveyed by the double-row conveyor 1. During installation, the outer edge of the baffle fold 221 is placed close to the end of the double-row conveyor 1 without affecting the normal operation of the double-row conveyor 1.

[0030] The lower end of the tipping hopper 2 has a long strip-shaped discharge port 23 arranged perpendicular to the baffle 22. The length direction of the discharge port 23 is perpendicular to the baffle 22, dividing the inner cavity of the tipping hopper 2 into two left and right parts. A single-row conveyor 4 is arranged below the discharge port 23.

[0031] A left slide 9 and a right slide 10 are respectively provided in the inner cavity of the overturning hopper 2 on both sides of the discharge port. Figure 5As shown, the left slide 9 and the right slide 10 are symmetrically arranged with the discharge port 23 as the center. The upper surfaces of the left slide 9 and the right slide 10 are inclined and gradually decrease in height from the junction of the baffle 22 to the far end. In addition, the upper surfaces of the left slide 9 and the right slide 10 are inclined at the same time with the outer end higher and the inner end lower. In addition, the upper surfaces of the left slide 9 and the right slide 10 are connected to the discharge port through the inclined left slide inner wall 91 and the right slide inner wall 111, respectively. The left slide inner wall 91 and the right slide inner wall 111 can be a plane or a slightly convex arc surface in the middle. Figure 5 As shown, the left and right slides 9 and 10 are both welded from stainless steel plates. The upper surface of the left slide 9, the inner wall 91 of the left slide, and the left sidewall of the discharge port 23 are formed from a single piece of stainless steel plate after being cut and bent, with their edges welded to the retaining ring 21 or the baffle 22. Similarly, the upper surface of the symmetrical right slide 10, the inner wall 111 of the right slide, and the right sidewall of the discharge port 23 are formed from a single piece of stainless steel plate after being cut and bent, with their edges welded to the retaining ring 21 or the baffle 22. The gap between the left and right sides of the discharge port 23 forms the discharge port itself. The noodles entering the tipping hopper 2 from the left and right ends of the baffle 22 first fall to the junction of the left slide 9 or the right slide 10 and the baffle 22. Here, the upper surface of the left slide 9 or the upper surface of the right slide 10 is the highest point. Under the action of gravity and inertia, the noodles slide downward along the upper surface of the left slide 9 or the upper surface of the right slide 10. While sliding down, the outer end of the noodles is constrained by the inner wall of the retaining ring 21, forming an arc-shaped sliding trajectory.

[0032] The outer side surface of the baffle 22 is docked with the end of the double-row conveyor 1 so that the noodles transported by the double-row conveyor 1 can fall into the tipping hopper 2 by relying on the inertia of movement. An upper guide plate 8 is fixedly installed in the middle position of the upper edge of the baffle 22 for blocking the movement of one end of the noodles entering the tipping hopper 2. The plate surface of the upper guide plate 8 is parallel to the upper edge line of the baffle 22, and the lower end of the upper guide plate 8 is located on the inner side of the baffle 22, and the upper end is inclined toward the outer side of the baffle 22. The central axis of the upper guide plate 8 is located in the middle of the baffle 22 and directly above the discharge port 23. The width of the upper guide plate 8 is equivalent to the width of the discharge port 23, which is only 1 / 5 to 1 / 10 of the length of the baffle 22. After the noodles 3 are fed into the tipping hopper 2 by the double-row conveyor 1, the inner end of the noodles 3 is blocked by the lower end of the upper guide plate 8 as soon as it passes the baffle 22. However, since the upper guide plate 8 is tilted and the blocked inner end of the noodles 3 only occupies a small part of its total length, when the noodles 3 do not break, the running speed of the inner end of the noodles 3 that passes the baffle 22 is reduced and lags behind the running of its outer end. The outer end of the noodles 3 rotates 90 degrees along the running trajectory of the large arc. The two rows of noodles 3 on both sides of the upper guide plate 8 rotate in opposite directions, and both rotate 90 degrees along the running trajectory of a large arc drawn by the outer ends of the noodles 3. While rotating, the row of noodles on the left side slides down along the upper surface of the left slide 9, and the row of noodles on the right side slides along the upper surface of the right slide 10. Finally, the two rows of noodles gather at the discharge port 23 between the left slide 9 and the right slide 10, and slide down along the discharge port 23.

[0033] like Figure 2-Figure 3 As shown, a lower guide plate 7 is provided below the upper guide plate 8, and the upper guide plate 8 is fixedly connected to the lower guide plate 7, and the two are welded together in a cross shape. The plate surface of the lower guide plate 7 is located on the central axis of the double-row conveyor 1, and the lower end of the lower guide plate 7 is provided with a left-leaning plate 71 and a right-leaning plate 72 that are symmetrically arranged and bent to both sides thereof, so that the lower guide plate 7 is in an inverted Y shape. The left-leaning plate 71 and the right-leaning plate 72 can be flat plates or curved plates; the upper guide plate 8 is located above the left-leaning plate 71 and the right-leaning plate 72. The lowermost end of the upper guide plate 8 is slightly higher than the highest ends of the left-leaning plate 71 and the right-leaning plate 72. The sides of the left-leaning plate 71 and the right-leaning plate 72 are fixedly welded to the inner wall of the baffle 22 and slightly lower than the upper edge of the baffle 22. The upper end of the lower guide plate 7 extends upward over the upper edge of the baffle 22 to form a support structure for the upper guide plate 8. The lower end of the upper guide plate 8 is divided into two halves with the upper end of the lower guide plate 7 as the centerline, with one half on each side of the lower guide plate 7. The left half is used to block the left row of noodles, and the right half is used to block the right row of noodles. In addition, the lower end of the upper guide plate 8 is provided with a rearward tilting plate 82 that is tilted toward the retaining ring 21, giving the lower end of the upper guide plate 8 a backward-bent plate shape. The rearward tilting plate 82 can be a flat plate or an arc-shaped plate.

[0034] The inner end of the noodles 3 that have passed the baffle 22 is blocked by the rear inclined plate 82 at the lower end of the upper guide plate 8. While the running speed is reduced, the noodles 3 continue to move backward under the action of inertia and reduce their height under the action of gravity. At this time, the inner end of the noodles 3 that have been reduced in height will be lifted by the left inclined plate 71 or the right inclined plate 72. Since the left inclined plate 71 or the right inclined plate 72 is inclined, the inner end of the lifted noodles 3 will not completely stop descending, but will only slow down the descending speed; at this time, the outer end of the noodles 3 draws a large arc of running trajectory and rotates 90 degrees, and quickly lowers its height along the outer side of the upper surface of the left slide 9 or the right slide 10. Finally, the noodles 3 completes the 90-degree rotation above the discharge port 23, and its inner end position is slightly higher and is at the proximal end close to the baffle 22, and the outer end position is slightly lower and is at the far end away from the baffle 22, and is arranged above the discharge port 23 in a slightly inclined state.

[0035] like Figure 1 、 Figure 6 As shown, the lower end of the discharge port 23 is connected to a vertical blanking device 5. This device is a pipe with a rectangular transverse cross-section that matches the discharge port and a Z-shaped longitudinal cross-section. This device is constructed from stainless steel sheets that have been bent and welded. The width and thickness of the pipe's inner cavity are comparable to the length and width of the discharge port 23. The noodles that fall through the discharge port 23 slide down the inclined channel of the vertical blanking device 5 and turn at the bend. During this process, the noodles collide with each other, straightening and arranging the noodles. Finally, a neatly arranged row of noodles is discharged from the lower end of the vertical blanking device and transported to the next process by a single-row conveyor 4.
