Description

Technical Field

[0001] This application relates to the field of food processing equipment technology, and in particular to a filling device for processing glutinous rice balls. Background Technology

[0002] In the mass industrial production of glutinous rice balls, the glutinous rice ball forming machine is the core equipment for achieving continuous production. It completes the automated transformation from raw materials to finished glutinous rice balls through standardized continuous actions of "dough tube forming - filling injection - cutting and rolling". However, in the entire production process, the filling addition step has long relied on manual operation, which has become a key bottleneck restricting the improvement of production efficiency and the reduction of labor intensity.

[0003] The current manual filling process is as follows: First, the well-mixed filling is transferred from the mixing machine to a transfer cart, which is then pushed to the filling hopper of each glutinous rice ball forming machine. Workers then use a shovel or their hands to scoop up the filling and add it spoonful by spoonful to the higher hopper of the forming machine. This process requires workers to frequently raise their arms, resulting in extremely high labor intensity and fatigue over long periods, thus affecting the efficiency and consistency of filling volume.

[0004] More importantly, the fillings for glutinous rice balls have unique physical characteristics: high viscosity, no flowability, and solid particles such as peanuts and walnuts are often added to improve the texture. This characteristic makes it difficult to adapt to existing conventional conveying equipment: if pumping equipment is used, the solid particles in the filling will be ground up by the pump, resulting in a decline in the texture of the glutinous rice balls; if conventional conveyor belts are used, the high-viscosity fillings easily stick to the conveyor belt, which not only wastes materials but is also difficult to clean and poses food safety risks. Utility Model Content

[0005] In order to improve the efficiency of adding filling in the production of glutinous rice balls, this application provides a filling device for glutinous rice ball processing.

[0006] The filling equipment for glutinous rice ball processing provided in this application adopts the following technical solution: it includes a mixing pot, a circular track located above each glutinous rice ball forming machine, a trolley moving along the circular track, a control system, a filling dispenser installed on one side of the mixing pot, a conveying mechanism for moving the hopper near the discharge port of the filling dispenser, the conveying mechanism including an online weighing sensor electrically connected to the control system, when the online weighing sensor detects that the filling in the hopper at the filling position of the hopper has reached the set weight, the filling dispenser will stop feeding and the conveying mechanism will transport the hopper to the full hopper grab position, a fixed plate is connected to the end of the trolley away from the circular track through a synchronous belt, a clamp for grabbing the hopper is installed on the fixed plate, and a scraping mechanism for moving the filling into the glutinous rice ball forming machine is installed on the fixed plate.

[0007] Optionally, the conveying mechanism also includes a frame on which multiple conveying rollers with the same structure are installed. The conveying rollers are electrically connected to the control system. The conveying rollers are evenly spaced to form a hopper release position, a hopper filling position, and a full hopper grab position. When the filling in the hopper is removed, the empty rail trolley will drive the hopper to move along the circular track to above the hopper release position.

[0008] Optionally, the clamp includes a linear module fixed to the fixed plate and electrically connected to the control system. There are two linear modules symmetrically arranged about the center line of the fixed plate. The linear modules are connected to lifting rods. A connector is provided at the end of the lifting rod away from the fixed plate. A positioning pin is provided on the connector. Positioning blocks that cooperate with the positioning pins are provided on both sides of the hopper. When the two lifting rods drive the positioning pins to move under the action of the linear modules, the hopper will be clamped by the lifting rods and move with the lifting rods.

[0009] Optionally, the scraping mechanism includes two vertical rods fixed to a fixed plate, symmetrically arranged about the center line of the fixed plate. A fixed shaft is provided at the end of the vertical rod away from the fixed plate, and a scraper is provided between the two fixed shafts. The scraper has a "U"-shaped structure suitable for the inner wall of the hopper. The hopper and the positioning block are provided with arc-shaped grooves that cooperate with the fixed shafts. A motor that drives the positioning pin to rotate and is electrically connected to the control system is provided in the connecting piece. When the motor drives the positioning pin to rotate, the fixed block and the hopper will rotate synchronously along the fixed shaft, and the filling in the hopper will be moved out of the hopper under the action of the scraper and its own gravity.

[0010] Optionally, one end of the connector is provided with a rotatable connecting plate, and there are multiple positioning pins, all of which are fixed on the connecting plate. A connecting hole for fixing the shaft to pass through is provided in the middle of the connecting plate.

[0011] Optionally, the scraper includes a blade holder connected to a fixed shaft, the blade holder having a "U"-shaped structure, and a blade detachably connected to the blade holder.

[0012] Optionally, the molding machine is equipped with a material shortage detection sensor. The material shortage detection sensor is existing technology. The material shortage detection sensor is connected to the control system. When the filling in the hopper of the molding machine is lower than the set value, the material shortage detection sensor sends a material demand signal to the control system, which controls the empty rail trolley to transport the hopper to the corresponding material dumping position of the molding machine. Multiple empty rail trolleys with the same structure are slidably connected on the circular track.

[0013] In summary, this application includes the following beneficial technical effects: The process of quantitative filling by a filling machine, automatic conveying by an empty rail trolley, and automatic unloading by a scraping mechanism replaces manual filling operations, significantly reducing labor intensity. In response to the high viscosity and solid particle content of glutinous rice ball fillings, a hopper that moves with the empty rail trolley is set up to avoid excessive friction between the filling and the equipment during the conveying process, protecting particles such as peanuts and walnuts from being damaged. The scraper adheres to the inner wall of the hopper, so there is no filling residue when unloading, solving the problem of high viscosity filling sticking and ensuring that the taste of glutinous rice balls is not affected by the conveying process. The conveying mechanism is equipped with a hopper release position, a hopper filling position, and a full hopper grab position. With the cooperation of the control system and the filling machine, the empty rail trolley can release, move, add material, and remove empty hoppers, ensuring the orderly progress of the material adding action. The air rail trolley is connected to a fixed plate. The fixed plate is equipped with linear modules and lifting rods that can move with the linear modules at both ends. The lifting rods are equipped with connectors and positioning pins. The hopper is equipped with positioning blocks at both ends. The positioning blocks are equipped with positioning holes that cooperate with the positioning pins to facilitate the clamping of the hopper. Vertical rods are set at both ends of the fixed plate. The scraper is connected between the two vertical rods by a fixed shaft. The fixed shaft passes through the connector. A motor that drives the positioning pin to rotate is set on the connector. Under the action of the control system, the motor drives the positioning block and the hopper to rotate through the positioning pin, and the filling is removed under the action of the scraper. The scraper consists of a blade holder and a detachable blade. When the blade wears out, only the blade needs to be replaced, instead of replacing the entire scraper, thus reducing maintenance costs.

Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0017] This application discloses a filling device for processing glutinous rice balls. For example... Figure 1-3As shown, the system includes a mixing pot 1, a circular track 6 located above each glutinous rice ball forming machine 8, a trolley 7 moving along the circular track 6, and a control system. A filling dispenser 2 is installed on one side of the mixing pot 1. The filling dispenser 2 is existing technology and includes a material bin. A displacement mechanism for moving the material bin is located below the material bin, and a spiral feeding mechanism for discharging the filling is located inside the material bin. A conveying mechanism for moving a hopper 15 is located near the discharge port of the filling dispenser 2. The hopper 15 is existing technology and has a semi-cylindrical structure. A support plate for cooperating with the conveying mechanism is located at the bottom of the hopper 15. The conveying mechanism includes an online weighing sensor electrically connected to the control system. The conveying mechanism also includes a frame, on which multiple identical conveying rollers are rotatably connected. The conveying rollers are electrically connected to a power source through the control system. The conveying rollers are evenly spaced to form a hopper release position 3, a hopper filling position 4, and a full-hopper gripping position 5. When the online weighing sensor detects that the filling in hopper 15 at the filling dispensing position 4 has reached the set weight, the filling machine 2 will stop feeding and the conveying mechanism will transport hopper 15 to the full-hopper gripping position 5. The end of the idler trolley 7 away from the circular track 6 is connected to a fixed plate 10 via a synchronous belt 9. The fixed plate 10 is moved by extending and retracting the synchronous belt 9, which is existing technology. The fixed plate 10 is equipped with a clamp for gripping the hopper 15. The clamp includes two linear modules 11 that are screwed onto the fixed plate 10 and electrically connected to the control system, arranged symmetrically about the center line of the fixed plate 10. The linear module 11 is bolted to a lifting rod 12. The end of the lifting rod 12 away from the fixed plate 10 is screwed to a connector 13. The connector 13 has a hollow cylindrical structure. The side of the connector 13 away from the lifting rod 12 is screwed to a positioning pin 14. The two sides of the hopper 15 are screwed to positioning blocks 16 that cooperate with the positioning pin 14. When the two lifting rods 12 drive the positioning pin 14 to move under the action of the linear module 11, the hopper 15 will be clamped by the lifting rods 12 and move with the lifting rods 12. A scraping mechanism for transferring filling into the glutinous rice ball forming machine 8 is provided on the fixed plate 10. The scraping mechanism includes two vertical rods 17 bolted to the fixed plate 10 and symmetrically arranged about the center line of the fixed plate 10. A vertical plate with an integral structure is provided at the end of the vertical rod 17 away from the fixed plate 10. A fixed shaft 18 is provided in the middle of the two vertical plates. A scraper 19 is fixed between the two fixed shafts 18 with screws. The scraper 19 has a "U" shaped structure suitable for the inner wall of the hopper 15. The hopper 15 and the positioning block 16 are provided with arc-shaped grooves 20 that cooperate with the fixed shafts 18. A motor that drives the positioning pin 14 to rotate and is electrically connected to the control system is provided in the connecting piece 13. When the motor drives the positioning pin 14 to rotate, the fixed block and the hopper 15 will rotate synchronously along the fixed shaft 18, and the filling in the hopper 15 will be moved out of the hopper 15 under the action of the scraper 19 and its own gravity. After the filling is removed from the hopper 15, the empty rail trolley 7 will move the hopper 15 along the circular track 6 to above the hopper release position 3.The molding machine 8 is equipped with a material shortage detection sensor, which is existing technology. The material shortage detection sensor is connected to the control system. When the filling in the hopper of the molding machine 8 is lower than the set value, the material shortage detection sensor sends a material demand signal to the control system, which controls the empty rail trolley 7 to transport the hopper 15 to the corresponding empty position of the molding machine 8. Multiple empty rail trolleys 7 with the same structure are slidably connected on the circular track 6.

[0018] In one embodiment, according to the appendix Figure 4 As shown, a rotatable connecting plate 21 is provided at one end of the connector 13. The motor is fixed to the inner wall of the connector 13 by a mounting base. The connector 13 is provided with a sliding groove that mates with the connecting plate 21. A ring-shaped gear is fixed to the connecting plate 21 with screws. A gear that meshes with the ring-shaped gear is keyed to the motor output shaft. There are multiple positioning pins 14, all of which are fixed to the connecting plate 21. A connecting hole for fixing the shaft 18 to pass through is provided in the middle of the connecting plate 21. A positioning hole that mates with the positioning pins 14 is provided on the positioning block 16.

[0019] In one embodiment, according to the appendix Figure 5 As shown, the scraper 19 includes a blade holder 22 connected to the fixed shaft 18. The blade holder 22 has a "U" shaped structure and a slot is provided on the blade holder 22. A blade 23 is detachably connected in the slot.

[0020] The implementation principle of the filling device for glutinous rice ball processing in this application embodiment is as follows: The control system is activated, and the set weight of the filling in hopper 15 is adjusted according to production needs. At the same time, the material shortage threshold of the filling hopper of the forming machine 8 is set. When the remaining filling in the hopper is lower than the set value, a material demand signal is triggered.

[0021] The filling machine 2 moves to connect with the discharge end of one of the mixing pots 1; the empty rail trolley 7 releases the synchronous belt 9, placing the empty hopper 15 at the hopper release position 3 of the conveying mechanism; the linear module 11 controls the lifting rod 12 to move under the control system, the positioning pin 14 separates from the positioning block 16, the hopper 15 is released, the empty rail trolley 7 collects the synchronous belt 9 and drives the fixed plate 10 to move upward, and the control system drives the conveying roller to transport the empty hopper 15 to the filling position 4.

[0022] The filling machine 2 starts under the control of the control system, injecting filling into the empty hopper 15 of the filling position 4. The online weighing sensor detects the weight of the hopper 15 in real time. When the weight reaches the set value, the sensor sends a signal to the control system. The control system immediately controls the filling machine 2 to stop filling and drives the conveyor roller to transport the hopper 15 full of filling from the filling position 4 to the full hopper grabbing position 5. The idle rail trolley 7 moves along the circular track 6 to above the full hopper grabbing position 5, releases the timing belt 9 to the set length, and the linear module 11 controls the movement of the boom 12 under the control of the control system. The positioning pin 14 is inserted into the positioning block 16 to clamp the hopper 15. The idle rail trolley 7 takes in the timing belt 9 and moves the hopper 15 upward. After the trolley 7 moves above the hopper of the target molding machine 8, the synchronous belt 9 drives the fixing plate 10 to descend, so that the hopper 15 is directly above the hopper of the molding machine 8. The control system starts the motor in the connecting piece 13. The motor drives the connecting plate 21 to rotate, which drives the positioning pin 14, positioning block 16 and hopper 15 to rotate synchronously around the fixed shaft 18. During the rotation of the hopper 15, the filling inside slides down under its own gravity. At the same time, the scraper 19 moves against the inner wall of the hopper 15 to completely scrape off the filling stuck to the inner wall of the hopper 15, ensuring that all the filling is completely poured into the hopper of the molding machine 8. After the filling is poured out, the motor rotates in the opposite direction, driving the hopper 15 to reset.

[0023] After the hopper 15 is reset, the synchronous belt 9 drives the fixed plate 10 to rise, and the idler trolley 7 moves along the circular track 6 to above the hopper release position 3, and so on. Multiple idler trolleys 7 follow the above process and, under the scheduling of the control system, continuously supply material to each forming machine 8, realizing the automated filling of the entire glutinous rice ball forming machine 8.

[0024] When the blade 23 of the scraper 19 becomes worn, after stopping the machine, remove the old blade 23 from the blade holder 22 and replace it with a new blade 23.

[0025] 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.
