Description

TECHNICAL FIELD

[0001] The present application relates to the field of packaging production lines, in particular to a non-fried instant noodle packaging production line. BACKGROUND

[0002] Compared with fried instant noodles, the noodles of non-fried instant noodles are more fluffy, and the forming degree and hardness are not as good as those of fried instant noodles. Therefore, when packaging non-fried instant noodles, a tray is needed to be added in the package to prevent the noodles from being deformed or even crushed by extrusion, so as to facilitate storage and transportation. Because of the addition of the tray, the packaged instant noodles are more regular, the packaging quality is stable and reliable, and quality problems are less likely to occur.

[0003] However, in actual production, noodles are manually put into the tray, and the personnel in the workshop need to continuously transport and put the noodles, making the workshop appear messy, and even causing pollution to the noodles. SUMMARY

[0004] Therefore, it is necessary to provide a non-fried instant noodle packaging production line, which does not need manual feeding of noodles, and avoids the mess of the workshop caused by personnel and pollution to the noodles.

[0005] A non-fried instant noodle packaging production line, comprising:

[0006] A lower tray machine is used to receive and transport stacked trays, and after separating the stacked trays, the lower tray machine sequentially transports the separated trays downstream;

[0007] A noodle arranging machine is used to synchronously supply noodles to a downstream double-supply machine packaging machine;

[0008] A double-supply packaging machine comprises a first supply machine and a second supply machine, the upstream of the first supply machine is connected to the downstream of the noodle arranging machine, the upstream of the second supply machine is connected to the downstream of the lower tray machine, and the end of the first supply machine intersects with the second supply machine, so that the noodles on the first supply machine fall into the tray on the second supply machine; and

[0009] A package feeding machine is installed above the second supply machine and is used to feed a package into the tray.

[0010] In one embodiment, the lower tray machine comprises:

[0011] A tray storage machine is used to transport stacked trays;

[0012] A tray feeding machine is curved and connected to the tray storage machine, and is used to gradually adjust the stacked trays from parallel transportation to vertical transportation;

[0013] The tray lowering machine, located at the bottom of the box feeding machine, is used to separate stacked trays and allow the separated trays to fall onto the second feeding machine;

[0014] The tray delivery machine, located at the outlet of the lower tray machine, is used to synchronously transport the separated trays to the second supply machine.

[0015] In one embodiment, the lower support machine includes:

[0016] The limiting part abuts against the side of the tray located at the bottom end to limit the tray;

[0017] A spiral column with a spiral protrusion on its surface, the spiral protrusion being used to engage above the edge of the bottommost tray and to separate the bottommost tray during rotation.

[0018] In one embodiment, the bottom end of the limiting part is inclined against the side of the tray, and the top end has an inclination adjustment structure.

[0019] In one embodiment, the production line further includes:

[0020] A horizontal sorting machine is used to arrange dough sheets in sequence and remove those that are not arranged in sequence.

[0021] A straight-line sorting machine, connected to the horizontal sorting machine, is used to arrange the dough sheets in a straight line.

[0022] In one embodiment, the transverse sorting machine includes a conveyor table, a baffle, and a paddle. One end of the baffle is disposed on one side of the conveyor table, and the other end extends to one side of the straight sorting machine. The paddle is disposed on the other side of the conveyor table, and the end of the conveyor table near the straight sorting machine has an overflow port.

[0023] In one embodiment, the noodle-laying machine includes a plastic chain conveyor, a pneumatic noodle-laying rod, a noodle-laying opening, a noodle-laying control terminal, and a multi-section belt conveyor arranged sequentially. The pneumatic noodle-laying rod and the noodle-laying opening are respectively located on both sides of one end of the plastic chain conveyor, and the multi-section belt conveyor is connected to the other end of the plastic chain conveyor. The noodle-laying control terminal is used to control the pneumatic noodle-laying rod, the plastic chain conveyor, and the multi-section belt conveyor.

[0024] In one embodiment, the production line further includes a metal detector, which is disposed between the straightening machine and the noodle-making machine.

[0025] In one embodiment, the dual-supply packaging machine further includes an auxiliary feeder and a packaging machine. The auxiliary feeder is located at the intersection of the first feeder and the second feeder, and the packaging machine is located downstream of the intersection of the first feeder and the second feeder.

[0026] In one embodiment, the auxiliary feeding machine includes a connecting platform and a feeding belt conveyor. One end of the connecting platform is connected to the outlet of the first feeder, and the other end extends directly above the second feeder. The feeding belt conveyor has a lever on its belt. The lever is used to push the dough at the outlet of the first feeder onto the connecting platform when the feeding belt conveyor rotates until the dough falls into the tray on the second feeder.

[0027] In the aforementioned non-fried instant noodle packaging production line, stacked trays are conveyed and separated into individual trays by a tray-lowering machine. These individual trays are then fed into a second feeder. Simultaneously, the noodle cakes are fed into a first feeder by a noodle-dispensing machine and fall into the trays on the second feeder at the junction of the first and second feeders. This production line eliminates the need for manual intervention in tray transportation and noodle cake dispensing, reducing logistics and labor costs, improving work efficiency, and minimizing the risk of cross-contamination.

[0044] The following is combined with Figures 1-8 This invention describes a non-fried instant noodle packaging production line.

[0045] like Figure 1 As shown, in one embodiment, a non-fried instant noodle packaging production line includes: a tray lowering machine 100, a noodle feeding machine 200, a double-supply packaging machine 300, and a packaging machine 400.

[0046] The tray lowering machine 100 is used to collect and transport stacked trays, and to separate the stacked trays and transport them downstream in sequence.

[0047] Specifically, the stacked trays are manually placed onto the tray lowering machine 100, which then transports the stacked trays downstream. During transport, the stacked trays are separated one at a time. The separated trays are then transported downstream until they fall into the dual-supply packaging machine 300.

[0048] The noodle-making machine 200 is used to simultaneously supply dough to the downstream dual-supply packaging machine 300.

[0049] Specifically, based on the dough demand of the dual-supply packaging machine 300, the speed of the dough feeding machine 200 is adjusted so that the dough feeding speed of the dough feeding machine 200 meets the needs of the dual-supply packaging machine 300.

[0050] The dough enters the dough sheet extrusion machine 200. The operator controls the extrusion machine 200 to remove any unqualified dough sheets. The extrusion machine 200 then transports the qualified dough sheets to the dual-supply packaging machine 500.

[0051] The dual-feed packaging machine 300 includes a first feeder 310 and a second feeder 320, used to convey dough sheets and trays and to place the dough sheets into the trays. See [link / reference] Figure 6 The upstream of the first feeder 310 is connected to the downstream of the noodle-making machine 200, the upstream of the second feeder 320 is connected to the downstream of the tray-feeding machine 100, and the ends of the first feeder 310 and the second feeder 320 intersect.

[0052] Specifically, the dough is conveyed to the first feeder 310 via the dough extrusion machine 200, and the trays are conveyed to the second feeder 320 via the tray lowering machine 100. The first feeder 310 and the second feeder 320 operate in a dual-line transport mode via two feeder belts, transporting the trays and dough simultaneously. The dough falls from the first feeder 310 into the trays on the second feeder 320. The feeder belts have multiple spaced baffles to push the dough or trays to move synchronously with the dual feeder belts and to evenly separate the dough or trays.

[0053] The bag feeder 400 is installed above the second feeder 320 and is used to feed the bags into the tray.

[0054] Specifically, the tray is conveyed to the second feeder 320 by the tray lowering machine 100, and the bag feeding machine 400 puts the material bag into the tray as the tray passes directly below.

[0055] The main body of the lower tray box machine 100 is installed on the second floor of the production workshop, and its end extends to the first floor of the production workshop to the double-supply packaging machine 300. The noodle sheeting machine 200, the double-supply packaging machine 300, and the bag feeding machine 400 are installed on the first floor of the production workshop as double-supply packaging machines.

[0056] In this embodiment of the non-fried instant noodle packaging production line, stacked trays are transported and separated into individual trays by a tray-lowering machine 100, and then fed into a second feeder 320. Simultaneously, noodles are fed into a first feeder 310 by a noodle-dispensing machine 200, and fall into a tray on the second feeder 320 at the junction of the first and second feeders 310. This production line eliminates the need for manual intervention in tray transport and noodle dispensing, reducing logistics and labor costs, improving work efficiency, and reducing the risk of cross-contamination due to the absence of manual intervention.

[0057] like Figure 2 As shown, in one embodiment, the tray feeding machine 100 includes a tray storage machine 110, a tray delivery machine 120, a tray feeding machine 130, and a tray dispensing machine 140.

[0058] Carton storage machine 110 is used to store and transport stacked trays.

[0059] Specifically, the trays are manually placed on the storage machine 110, which then transports them to the delivery machine 120.

[0060] The box feeder 120 is curved and connected to the box storage machine 110. It is used to gradually adjust the stacked trays from parallel conveying to vertical conveying.

[0061] Specifically, the trays are transported to the box feeder 120 via the box storage machine 110. The trays transported by the box feeder 120 are gradually tilted, changing from a parallel state to a vertical state. The individual trays also change from being perpendicular to the ground to being parallel to the ground. At this time, the trays are adjusted and transported to the lower tray machine 130 by the box feeder 120.

[0062] The tray unloading machine 130, located at the bottom of the box feeder 120, is used to separate stacked trays and allow the separated trays to fall onto the second feeder 320.

[0063] Specifically, the vertically stacked trays are transported by the tray feeder 120 to the tray unloading machine 130, where the tray unloading machine 130 separates the stacked trays.

[0064] The tray feeding machine 140, located at the exit of the tray feeding machine 130, is used to synchronously transport the separated trays to the second feeding machine 320. This transports the trays from the second floor of the production workshop to the first floor.

[0065] like Figure 3 As shown, in one embodiment, the lower support 130 includes a limiting part 133 and a spiral column 132.

[0066] A limiting part 133 abuts against the side of the tray located at the lowest end to limit the tray. The bottom end of the limiting part 133 is inclined against the side of the tray, and the top end has an inclination adjustment structure 134.

[0067] Specifically, when trays fall from the lower tray machine 100 to the double-feed packaging machine 300, the descent of the trays needs to be limited so that the auger 132 can separate them. The inclination of the limiting part 133 needs to be adjusted according to the radial dimension of the trays so that the limiting part 133 can support the stacked trays and adjust the height of the stacked trays, and separate each tray from the stacked trays sequentially when the auger 132 rotates. The inclination adjustment structure 134 includes a support plate 1341, a connecting plate 1342, a support column 1343 and a connecting rod 1344. The support plate 1341 has two parallel oblong holes. The connecting plate 1342 has an arc-shaped hole opposite to one of the oblong holes. The connecting plate 1342 is connected to the support plate through the other oblong hole by a fastener. An adjustable screw can be set between the arc-shaped hole and the opposite oblong hole. One end of the support column 1343 is fixed to the side of the connecting plate 1342 facing away from the support plate 1341, and the other end is sleeved on one end of the connecting rod 1344. The other end of the connecting rod 1344 is connected to the limiting part 133. The relative position between the connecting plate 1342 and the support plate 1341 can be adjusted through two parallel oblong holes, and the relative angle can be adjusted through an arc-shaped hole, thereby adjusting the inclination of the connecting rod 1344. The support column 1343 is sleeved on the connecting rod 1344 through a round hole at its end. The relative position between the support column 1343 and the connecting rod 1344 can be adjusted through this round hole, thereby adjusting the height of the limiting part 133.

[0068] The spiral column 132 has a spiral protrusion 131 on its surface, which is used to engage above the edge of the bottommost tray and to separate the bottommost tray when rotated.

[0069] Specifically, during the process of the tray falling from the lower tray machine 100, the limiting part 133 limits the tray, and the rotating spiral column 132 causes the spiral protrusion 131 to separate the bottom tray. After the stacked trays are separated here, they fall to the dual-supply packaging machine 300.

[0070] The tray unloading machine 130, through the combination of the limiting part 133, the spiral column 132 and the spiral protrusion 131, orderly separates the stacked trays, avoiding the messy distribution of trays in the automatic production line and enhancing the cleanliness of the production line.

[0071] like Figure 4 As shown, in one embodiment, the noodle-laying machine 200 includes a plastic chain conveyor 210, a pneumatic noodle-laying rod 220, a noodle-laying opening 230, a noodle-laying control terminal 240, and a multi-section belt conveyor 250 arranged sequentially. The pneumatic noodle-laying rod 220 and the noodle-laying opening 230 are respectively located on opposite sides of one end of the plastic chain conveyor 210, and the multi-section belt conveyor 250 is connected to the other end of the plastic chain conveyor 210. The noodle-laying control terminal 240 is used to control the pneumatic noodle-laying rod 220, the plastic chain conveyor 210, and the multi-section belt conveyor 250.

[0072] Specifically, after the dough enters the dough feeding machine 200, the dough feeding control terminal 240 is manually operated. When the dough feeding speed of the dough feeding machine 200 is greater than the dough feeding demand of the dual-feed packaging machine 300, and the dough becomes congested on the plastic chain conveyor 210, the pneumatic dough feeding rod 220 is controlled to discharge the dough located at the front end of the plastic chain conveyor 210 from the dough feeding port 230.

[0073] like Figure 5 and Figure 6 As shown, in one embodiment, the dual-supply packaging machine 300 further includes an auxiliary feeder 330 and a packaging machine 340. The auxiliary feeder 330 is located at the intersection of the first feeder 310 and the second feeder 320, and the packaging machine 340 is located downstream of the intersection of the first feeder 310 and the second feeder 320. Specifically, the auxiliary feeder 330 includes a connecting platform 332 and a feeding belt 334. One end of the connecting platform 332 is connected to the outlet of the first feeder 310, and the other end extends directly above the second feeder 320. The belt of the feeding belt 334 has a lever 3342, which is used to push the dough cake located at the outlet of the first feeder 310 onto the connecting platform 332 when the feeding belt 334 rotates, until the dough cake falls into the tray on the second feeder 320. After the dough cake is put into the tray, it is conveyed to the packaging machine 540 for final packaging.

[0074] At the intersection of the first feeder 310 and the second feeder 320, it is necessary to ensure that the dough from the first feeder 310 falls into the tray of the second feeder 320. However, since both the first feeder 310 and the second feeder 320 are designed with a belt conveyor-like circulating design, it is difficult for the end of the first feeder 310 to extend directly above the second feeder 320. Otherwise, mechanical collisions or large vertical distances would occur. Large vertical distances would increase the space occupied by the machine, and when the dough falls from the higher position of the first feeder 310 into the tray of the second feeder 320, a large impact would occur, which would cause the dough to break and the tray to shift. With the aforementioned auxiliary feeding machine 330, when the first feeder 310 delivers the dough to the end, the feeding belt 334 rotates and drives the lever 3342 to push the dough located at the end of the first feeder 310 onto the connecting table 332 until the dough falls into the tray on the second feeder 320. There is no need to directly extend the first feeder 310 to the top of the second feeder 320, so there will be no mechanical collision, and the dough will not be broken or the tray will be displaced.

[0075] In this embodiment, the conveyor table of the dual-supply packaging machine 300 is provided with multiple partitions at intervals. These partitions are equally spaced. On the one hand, the partitions can push the dough into the first feeder 310 at the entrance. On the other hand, they can keep the dough on the first feeder 310 evenly distributed and keep the trays on the second feeder 320 evenly distributed.

[0076] like Figure 7 As shown, in one embodiment, the production line further includes a metal detector 800, a horizontal sorting machine 600, and a straight sorting machine 700; wherein, the horizontal sorting machine 600 is used to arrange the dough pieces sequentially and remove those that are not arranged sequentially; the straight sorting machine 700 is connected to the horizontal sorting machine 600 and is used to arrange the dough pieces sequentially in a straight line; the metal detector 800 is disposed between the straight sorting machine 700 and the dough arrangement machine 400.

[0077] Specifically, the originally irregular dough sheets are arranged sequentially by the horizontal sorting machine 600. Dough sheets that are not arranged sequentially are discarded. The sequentially arranged dough sheets then enter the linear sorting machine 700, where they are arranged in a straight line. After passing through the linear sorting machine 700, the dough sheets reach the noodle-laying machine 200. While being conveyed by the noodle-laying machine 200, they pass through the metal detector 800, which is responsible for detecting impurities in the food to ensure food safety.

[0078] The metal detector 800 in this embodiment automatically detects metal impurities in food, effectively preventing impurities from adhering to food during factory operations, ensuring food quality, and maintaining food safety.

[0079] In this embodiment, the horizontal sorting machine 600 of the production line includes a conveyor table 610, a baffle 630 and a paddle 620. One end of the baffle 630 is disposed on one side of the conveyor table 610, and the other end is bent and extended to one side of the straight sorting machine 700. The paddle 620 is disposed on the other side of the conveyor table 610. The end of the conveyor table 610 near the straight sorting machine 700 has an overflow port 640.

[0080] Specifically, the dough is randomly placed into the conveyor 610 and begins to be conveyed. The dough near the paddle 620 is arranged into a sequential arrangement by the paddle, and the dough near the baffle 630 is arranged into a sequential arrangement by the baffle. The dough that is not arranged in a sequential arrangement is rejected through the overflow port 640, and the sequentially arranged dough enters the linear sorting machine 700.

[0081] The horizontal sorting machine 600 in this embodiment automatically sorts disordered dough into an orderly one, greatly reducing labor costs.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
