Description

Technical Field

[0001] This application relates to the field of dumpling processing technology, and in particular to a filling mixing system for dumpling processing. Background Technology

[0002] In large-scale dumpling production, the filling preparation stage is the core process that determines the taste and quality of dumplings. This stage involves a wide variety of ingredients, including vegetables, meat, protein, and other seasonings, with strict requirements for ingredient ratios. This places extremely high demands on the automation and coordination of production equipment. However, current mainstream dumpling filling preparation methods suffer from fragmented operations, poor coordination, insufficient precision, and high reliance on manual labor, severely restricting production efficiency and product quality.

[0003] In current production, the pretreatment and batching of different materials such as vegetables, meat, and fillings mostly rely on independent equipment, and manual intervention is required throughout the entire process, lacking a unified integrated batching unit. After pretreatment, vegetables need to be manually transferred to a temporary storage area, while meat fillings are prepared separately using another set of equipment. This not only increases material loss during the transfer process but also makes the freshness of the materials prone to decline due to deviations in the timing of the transfer.

[0004] Material transportation relies heavily on manual trolleys or fixed-track carts, which is not only labor-intensive but also inefficient, especially when multiple mixing pots are short of material at the same time, leading to supply and demand mismatches. Material shortage detection in the mixing pots also relies heavily on manual observation, lacking automated detection, resulting in slow replenishment response and causing the mixing pots to idle while waiting. Summary of the Invention

[0005] In order to improve the overall efficiency of mixing fillings during dumpling processing, this application provides a filling mixing system for dumpling processing.

[0006] The dumpling processing filling mixing system provided in this application adopts the following technical solution: it includes a transport unit, which is a stainless steel roller conveyor, used to drive the standard turnover basket to move. The transport unit is equipped with a pressure weighing module for real-time detection of the material quality in the turnover basket. The ingredient preparation unit includes a vegetable ingredient module, a meat ingredient module, a protein ingredient module, and a small ingredient ingredient module. Each ingredient preparation module is independent of each other but data-related. Each ingredient preparation module is equipped with a material pretreatment structure, a temporary storage bin, and a material release control mechanism. The temporary storage bin is a stainless steel cone-shaped structure used to store pretreated dumpling processing materials. The material release control mechanism can control the release of materials from the temporary storage bin to the turnover basket. The filling mixing unit includes at least one filling mixing pot, which is equipped with a temporary storage hopper after mixing. The pot wall of the temporary storage hopper after mixing is provided with a cooling jacket to control the temperature of the stored mixed filling within a preset range. A material pouring unit is provided for each of the mixing pots. The material pouring unit is equipped with a card reader for identifying the RFID chip on the turnover basket. The card reader is electrically connected to the central control system and is used to drive the turnover basket to flip after identifying and verifying that the material information is correct, so as to pour the material into the corresponding mixing pot. The material unloading unit includes a base with a cover mounted on it. A power component, comprising a push rod motor electrically connected to a power source via a central control system, is located on one side of the cover. A rotating shaft, cooperating with the power component, is housed within the cover. The rotating shaft has a clamping component for engaging the side of a turnover basket. When the power component rotates the shaft, the clamping component causes the turnover basket on the transport unit to rotate 90 degrees around the shaft, unloading the material into a temporary storage hopper before the mixing pot. The clamping component includes multiple swing arms evenly spaced along the rotating shaft, with each swing arm connected to a clamping member at its end furthest from the shaft, engaging with a groove on the edge of the turnover basket. An RFID reader is located on the cover. The cover has a through hole for the rotating shaft to pass through. Two seats, symmetrically arranged about the base's centerline, are mounted on the base. Each seat contains a bearing with an interference fit to the rotating shaft. A connecting rod is rotatably connected to the output shaft of the push rod motor, and the end of the connecting rod away from the push rod motor is fixedly connected to the rotating shaft. A counterweight is provided at the end of the rotating shaft away from the push rod motor.

[0007] The central control system is electrically connected to the batching unit, the transport unit, the mixing unit, and the unloading unit, respectively. It is used to control the batching unit to release materials into the turnover basket, receive the quality signal from the weighing module and control the material release to stop, dispatch the transport unit to move the turnover basket full of materials to the corresponding mixing pot, and control the unloading unit to complete the material unloading.

[0009] Optionally, the temporary storage bin is fixed to the end of the ingredient dispensing module via a support frame. A weighing sensor is installed on the support frame to detect the remaining material level in the temporary storage bin. The weighing sensor is electrically connected to the central control system. When the material level in the temporary storage bin falls below a preset threshold, the central control system controls the material pretreatment structure to initiate replenishment. The temporary storage bin is fixed to the end of the vegetable preparation production line via a support frame. Weighing sensors for measuring the weight of vegetables in the temporary storage bin are installed at two opposite corners of the support frame. The temporary storage bin includes an inlet, a storage body, and a discharge bin. The conveyor belt of the vegetable preparation production line extends to the inlet of the temporary storage bin, and the discharge bin is equipped with a discharge mechanism for removing materials. The feeding hopper is a hollow cylindrical structure. One end of the feeding hopper is connected to the hopper body, and the other end is provided with a discharge port. The discharge mechanism includes a feeding lever located in the middle of the feeding hopper and rotatably connected to the side wall of the feeding hopper. Multiple feeding plates are provided on the feeding lever and are arranged symmetrically about the feeding lever. When the feeding lever is rotated, the vegetables inside the hopper will move to the discharge port under the action of the feeding plates. A motor is provided on the side wall of the feeding hopper, and the motor output shaft is connected to the feeding lever via a coupling. The central control system is electrically connected to the motor. The temporary storage hopper has a conical structure. The support frame includes four identical support rods, and the support rods are provided with grooves for placing weighing sensors.

[0010] Optionally, the mixing pot is equipped with a material shortage detection mechanism, which is a liquid level sensor used to detect the remaining amount of filling in the pot and send a material shortage signal; the material shortage detection mechanism is electrically connected to the central control system, and the central control system can send a conveying command to the transport unit according to the priority of the material shortage signals of multiple mixing pots.

[0011] Optionally, the central control system includes a material metering module and an action coordination module: the material metering module is used to store the material ratio and target quality parameters corresponding to each of the mixing pots, and supports the preset and rapid switching of multiple SKU filling formulas; the action coordination module is used to synchronously control the timing of the feeding action of the feeding control mechanism, the movement action of the transport unit, and the flipping action of the pouring unit.

[0012] Optionally, the central control system is also electrically connected to the RFID chip on the turnover basket and the photoelectric sensor on the transportation unit. The RFID chip identifies the material information and batch information in the turnover basket, and the photoelectric sensor realizes the positioning and queue calculation of the turnover basket.

[0013] Optionally, the transportation unit is also equipped with an empty crate processing system, including a crate return line and a crate washing area. The crate washing area is equipped with a crate turning machine, a washing and drying assembly, and a clean crate temporary storage area. Non-meat crates are washed, dried, and then diverted to the ingredient preparation unit, while meat crates are directly returned for reuse. The operation logic of the empty crate processing system is uniformly scheduled by the central control system.

[0014] In summary, this application includes the following beneficial technical effects: By using dedicated ingredient modules for vegetables, meat, protein, and condiments, combined with a feeding control mechanism adapted to the characteristics of the materials, problems such as material blockage, adhesion, and proportioning errors are reduced. The temporary storage bin uses gravity to achieve material gravity flow, reducing residue and waste. In conjunction with the pressure weighing module of the transportation unit, the ingredient error rate is reduced. The weighing sensor on the support frame of the temporary storage bin detects the remaining material in real time. When the material level is lower than the preset threshold, the central control system triggers the pre-processing structure to replenish the material, ensuring continuous material supply in the batching process. The RFID reader of the unloading unit is linked with the RFID chip on the turnover basket to automatically identify material information, batch information and target mixing pot. The flipping action is only started after the central control system verifies that there are no errors. The central control system’s material metering module supports preset and quick switching of multiple SKU recipes, and the action coordination module synchronously controls the timing of feeding, transportation and flipping actions. Through linkage with the material shortage detection mechanism and photoelectric sensors, the central control system can schedule the transportation unit according to the material shortage priority of the mixing pot. The cooling jacket of the temporary storage hopper after mixing controls the temperature of the filling below the set temperature, effectively preventing the filling from spoiling; the empty basket handling system processes materials separately according to their type, reducing the risk of cross-contamination, while also enabling the recycling of turnover baskets.

Detailed Implementation

[0017] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0018] This application discloses a filling mixing system for dumpling processing. For example... Figure 1-8 As shown, it includes a transport unit, which is a stainless steel roller conveyor, used to move standard turnover baskets. The transport unit is equipped with a pressure weighing module for real-time detection of the material quality inside the turnover baskets. The transport unit is also equipped with a photoelectric sensor for detecting the position of the turnover baskets.

[0019] The ingredient preparation unit includes vegetable, meat, protein, and topping modules. Each module is independent yet interconnected. Each module features a material pre-processing structure, a temporary storage bin, and a feeding control mechanism. The material pre-processing structure is an automated pre-processing production line, sequentially including washing, dicing, and draining modules. This material pre-processing structure is existing technology. The temporary storage bin is a stainless steel conical structure used to store pre-processed dumpling materials. The conical shape facilitates the downward movement of vegetables to the bottom of the bin under their own weight, preventing material accumulation. The temporary storage bin is fixed to the end of the vegetable preparation line by a support frame 2. Located below the end of the conveyor belt, it prevents material spillage. Weighing sensors for measuring the weight of vegetables in the temporary storage bin are located at two opposite corners of the support frame 2. These weighing sensors are existing technology. The support frame 2 includes four identical support rods 9. Each support rod 9 has a groove for placing a weighing sensor. The weighing sensor is electrically connected to the central control system. When the weighing unit detects that the weight of the vegetables in the temporary storage bin 1 is lower than a set value and transmits a signal to the central control system, the central control system will control the vegetable preparation production line to start operating. The feeding control mechanism can control the release of materials from the temporary storage bin to the turnover basket. The feeding control mechanism is adapted to the type of ingredient module: the vegetable ingredient module's temporary storage bin has a discharge mechanism at the bottom; the meat ingredient module's temporary storage bin has a discharge auger inside; and the small ingredient module is equipped with an automatic and manual feeding station, with the small ingredient carrier equipped with an RFID chip. The discharge mechanism, the discharge auger, and the drive components of the automatic small ingredient feeding station constitute the feeding control mechanism for the corresponding ingredient module, and are electrically connected to the central control system. The temporary storage bin 1 includes an inlet 3, a bin body 4, and a discharge bin 5. The bin body 4 and the discharge bin 5 are an integral structure, and their materials include, but are not limited to, stainless steel. The conveyor belt of the vegetable preparation line extends to the inlet 3 of the temporary storage bin 1. The discharge bin 5 is equipped with a discharge mechanism for removing materials. The discharge bin 5 is a hollow cylindrical structure. One end of the discharge bin 5 is connected to the bin body 4, and the other end is provided with a discharge port. The discharge mechanism includes a feeding rod 6 located in the middle of the discharge bin 5 and rotatably connected to the side wall of the discharge bin 5. A circular hole is provided in the middle of the discharge bin 5 for the feeding rod 6 to pass through. A bearing that is interference-fitted with the feeding rod 6 is fixed on the outer wall of the discharge bin 5 by a bracket. The part of the feeding rod 6 located inside the discharge bin 5 is provided with feeding plates 7. There are four feeding plates 7, which are arranged symmetrically about the feeding rod 6. When the feeding rod 6 is rotated, the vegetables in the bin body 4 will be moved to the discharge port by the feeding plates 7. A motor 8 is fixed to the side wall of the feeding hopper 5 by mounting screws. The output shaft of the motor 8 is connected to the feeding rod 6 via a coupling. The central control system is electrically connected to the motor 8. When the central control system receives the feeding signal, it will drive the motor 8 to rotate and move the set amount of vegetables out. The control center can interface with the control system signal of the subsequent filling process to receive feeding instructions.

[0020] A material pouring unit is provided for each mixing pot 10. The unit is equipped with a reader for identifying the RFID chip on the turnover basket. The reader is electrically connected to the central control system and, after verifying the material information, drives the turnover basket to flip, pouring the material into the corresponding mixing pot 10. The material pouring unit includes a base 11, on which a cover 12 is fixed with screws. The cover 12 has a U-shaped cross-section. A power component is provided on one side of the cover 12. The power component includes a push rod motor 13, which is fixed to the cover 12 with screws via a mounting base. The push rod motor 13 is existing technology and is electrically connected to a power source via the central control system. A rotating shaft 14, which works with the power component, is provided inside the cover 12. Through holes 17 are provided on both sides of the cover 12 near the base 11 for the rotating shaft 14 to pass through. Two seats 18 are fixed to the base 11 with screws. The seats 18 are symmetrically arranged about the center line of the base 11 and contain bearings that are interference-fitted with the rotating shaft 14. A retaining component is provided on the rotating shaft 14 for engaging the side of the turnover basket. When the power unit drives the rotating shaft 14 to rotate, the retaining component will cause the turnover basket located on the transport unit to rotate 190 degrees around the rotating shaft 14 and pour the material into the temporary storage bin in front of the mixing pot 10. The retaining component includes a swing arm 15 fixed to the rotating shaft 14 by screws. One end of the swing arm 15 is provided with a round hole for the rotating shaft 14 to pass through. There are multiple swing arms 15, which are evenly spaced along the rotating shaft 14. The end of each swing arm 15 away from the rotating shaft 14 is provided with a retaining member 16 for engaging with the retaining groove on the edge of the turnover basket. The retaining member 16 includes a retaining plate fixed to the swing arm 15 by screws. The side of the retaining plate away from the swing arm 15 is glued with a support strip that abuts against the side of the turnover basket. There are multiple support strips, which are evenly spaced along the length of the retaining plate. The support strips are made of rubber. An RFID reader is screwed onto the cover 12, working in conjunction with a photoelectric sensor on the transport unit. Both the RFID reader and the photoelectric sensor are existing technologies. The RFID reader can read the type of material stored in the turnover basket and the target mixing pot 10. The photoelectric sensor is used to detect whether the turnover basket has reached the preset flipping position. Both the RFID reader and the photoelectric sensor are electrically connected to the central control system. After the central control system identifies and verifies the RFID chip information on the turnover basket, it controls the power component to drive the rotating shaft 14 to rotate. A connecting rod 19 is rotatably connected to the output shaft of the push rod motor 13. The end of the connecting rod 19 away from the push rod motor 13 is fixedly connected to the rotating shaft 14. A counterweight 120, made of cast iron, is screwed onto the end of the rotating shaft 14 away from the push rod motor 13. The counterweight 120 is used to balance the eccentric load of the rotating shaft 14, the swing arm 15, the clamping component, and the turnover basket.

[0021] The filling mixing unit includes at least one mixing pot 10. The mixing pot 10 is equipped with a post-mixing storage hopper, the wall of which has a cooling jacket to control the temperature of the stored, mixed filling within a preset range. The mixing pot 10 is equipped with a low-filling detection mechanism, which is a liquid level sensor used to detect the remaining filling in the pot and issue a low-filling signal. The low-filling detection mechanism is electrically connected to a central control system, which can issue conveying instructions to the transport unit based on the priority of low-filling signals from multiple mixing pots 10.

[0022] The central control system is electrically connected to the batching unit, transport unit, mixing unit, and unloading unit. It controls the batching unit to release materials into the turnover baskets, receives quality signals from the weighing module and controls the stopping of material release, schedules the transport unit to move the fully loaded turnover baskets to the corresponding mixing pot 10, and controls the unloading unit to dump the materials. The central control system includes a material metering module and a motion coordination module: the material metering module stores the material ratios and target quality parameters for each mixing pot 10, supporting the preset and rapid switching of multiple SKU filling recipes; the motion coordination module synchronously controls the timing of the material release mechanism, the transport unit's movement, and the unloading unit's flipping action. The central control system uses an industrial-grade PLC controller with an integrated touchscreen interface. The material metering module can store multiple filling recipes, and the motion coordination module uses a timing control algorithm to reduce the connection time between each link; photoelectric sensors enable precise positioning and queue management of the turnover baskets.

[0023] The transportation unit is also equipped with an empty crate processing system, including a crate return line and a crate washing area. The crate washing area is equipped with a crate flipping machine, a washing and drying unit, and a clean crate temporary storage area. Non-meat crates are washed and dried and then diverted to the ingredient preparation unit, while meat crates are directly returned for reuse. The operation logic of the empty crate processing system is uniformly scheduled by the central control system.

[0024] The implementation principle of the dumpling filling mixing system in this embodiment is as follows: Turn on the power and call up the recipe parameters for the pork and mushroom dumplings through the touch screen interface of the central control system. Each pot requires 275kg of vegetables, 150kg of meat, 75kg of protein, and 10kg of seasonings. The replenishment thresholds for each temporary storage compartment, the shortage threshold for the mixing pot, and the temperature of the cooling jacket are preset.

[0025] When the filling liquid level in mixing pot #1 is lower than the material shortage threshold, the material shortage detection mechanism sends a material shortage signal to the central control system. The central control system determines the priority of the signal according to the production plan. If multiple pots are short of material, they are sorted according to the production progress and then a material dispensing instruction is sent to the material dispensing unit. At the same time, the empty turnover baskets of the transportation unit are dispatched to each material dispensing module.

[0026] The empty turnover basket is first moved by a stainless steel roller conveyor to the temporary storage bin of the vegetable ingredient module. A photoelectric sensor triggers positioning, and the central control system opens the pneumatic valve at the bottom of the temporary storage bin, allowing the vegetables to fall into the turnover basket. A pressure weighing module collects weight data in real time and feeds it back to the central control system. When the weight reaches 275kg, the discharge mechanism closes, and the turnover basket moves to the meat ingredient module. The discharge auger starts feeding until the weight reaches 150kg, completing the batching of protein and other ingredients sequentially. During the batching process, the RFID chip on the ingredient carrier records batch information, and the RFID chip on the turnover basket is synchronously linked to all material information.

[0027] Under the scheduling of the central control system, the turnover baskets fully loaded with materials move along the roller conveyor towards the No. 1 mixing pot. Photoelectric sensors provide real-time feedback of position information to achieve queue management. When the turnover baskets reach the unloading unit next to the No. 1 mixing pot, the roller conveyor stops running, completing precise positioning.

[0028] The RFID reader of the material dispensing unit reads the RFID chip information on the turnover basket and transmits the material type, target mixing pot, and batch information to the central control system. After the central control system verifies that the information is correct, it controls the flipping mechanism to start, which drives the turnover basket to flip and the material is poured into the No. 1 mixing pot. After the material is poured, the flipping mechanism resets.

[0029] After the mixing pot finishes mixing the filling, it transports the filling to the post-mixing storage hopper. The cooling jacket is activated to control the filling temperature below the set temperature. When the material in the storage hopper is below the threshold, the central control system triggers the batching, transportation and unloading cycle again to ensure continuous material supply.

[0030] After the empty crates are unloaded, they enter the empty crate processing system driven by the roller conveyor. The central control system dispatches the crates according to the material type identified by the RFID chip: meat crates return directly to the meat batching module through the return line, while non-meat crates enter the crate washing area, are flipped by the crate flipping machine, high-pressure cleaned and dried, and then transported to the clean crate temporary storage area to wait for the next batching call.

[0031] The central control system records operational data for each stage in real time, including ingredient preparation time, weight, transportation route, unloading time, and batch information. This data can be queried or exported via a touchscreen, enabling full traceability of materials from ingredient preparation to filling mixing. When the system malfunctions, such as RFID identification failure or excessive weighing error, it immediately issues an alarm signal, facilitating manual intervention.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
