[0008] The filling assembly includes a filling drive mechanism, a filling screw, a filling hopper, and a filling nozzle. The filling screw is rotatably connected inside the filling hopper and is perpendicular to the conveying surface of the conveyor belt. The filling screw is connected to the filling drive mechanism. The filling nozzle is connected to the bottom of the filling hopper and is located at the center of the filling cavity. The outlet of the filling nozzle is located above the outlet of the filling cavity.

[0009] In this embodiment, the bottom of the manifold is provided with a V-shaped diversion guide surface.

[0010] In this embodiment, the dough feeding assembly also includes a dough hopper. The outlet of the dough hopper is connected to the top of the dough box. There are multiple dough screws and multiple partitions in the dough box. There is a partition between every two adjacent dough screws. The length of the partition is less than the length of the dough box. The partition is located on the side of the dough box away from the confluence channel. The outlet of the dough hopper is directly opposite the partition.

[0011] In this embodiment, the bottom of the filling cavity is provided with a filling channel in the shape of an inverted frustum.

[0012] In this embodiment, the food filling device for evenly covering food also includes a sealing assembly. The sealing assembly includes a sealing drive mechanism, a cover plate, a bottom plate, a linkage structure, and multiple claws. The bottom plate and the cover plate are both annular.

[0017] The dough blanks in the dough material box are conveyed to the manifold via a dough screw. Two branch channels are symmetrical about the inlet axis of the manifold, ensuring that the dough blanks are evenly distributed and fed into the two branch channels. These two branch channels are also symmetrically arranged on opposite sides of the filling cavity. The two branch channels inject the dough blanks from opposite sides of the filling cavity with a high consistency of flow rate. The dough blanks flow in opposite directions and converge in the filling cavity at the same horizontal plane, avoiding large areas of voids in the filling cavity and effectively improving the integrity of the dough blank filling. It effectively improves the consistency of dough thickness when used for filling, avoiding areas where the dough is too thin or too thick, resulting in a better filling effect. Furthermore, by enclosing the filling cavity around the filling nozzle's outlet, it ensures that the dough inside the filling cavity surrounds the nozzle's outlet and forms a food dough. The filling screw compresses the filling, outputting it from the filling nozzle to the center of the food dough, thus achieving the filling action. This not only ensures a consistent distance between the filling and the edge of the food dough during filling, resulting in high filling precision and a good filling effect, but also minimizes manual intervention, increases filling efficiency, ensures high consistency in filling results, and leads to high-quality food products.

[0034] In the food processing industry, fillings for filled foods such as mooncakes and sandwich pastries need to be injected into the dough during processing. After wrapping, the food product is obtained, and the quality of the filling directly affects the quality of the food product. In traditional techniques, the filling process is done manually, and the dough needs to be shaped before wrapping to form a concave structure to accommodate the filling. This process is cumbersome and prone to uneven wrapping and inconsistent thickness, resulting in poor filling and ultimately affecting the taste and quality of the food product.

[0035] In some technologies, a screw extrusion is used to form dough sheets and output them to a conveyor belt. The screw also extrudes the filling and transports it to the dough sheets on the conveyor belt to achieve filling. However, the dough sheets produced by this structure have problems with uneven thickness and insufficient filling precision, resulting in poor filling effect and poor quality of the food products.

[0036] The following is for reference only. Figure 1 To be continued Figure 6 This invention describes a food filling device with evenly distributed filling, which provides uniform dough thickness, high filling accuracy, good filling effect, and high-quality food products.

[0037] Reference Figures 1 to 6 A food filling device for evenly covering filling according to an embodiment of the present invention includes:

[0038] The frame 100 is equipped with a conveyor belt 110, which is used to transport food products;

[0039] The dough feeding assembly 200 includes a dough conveying drive mechanism 210, a dough material box 220, a dough screw 230, and a filling head 240. The dough conveying drive mechanism 210 and the dough material box 220 are both connected to the frame 100. The filling head 240 is located directly above the conveyor belt 110 and connected to one side of the dough material box 220. The dough screw 230 is rotatably connected inside the dough material box 220, and its axis is parallel to the conveying surface of the conveyor belt 110. The dough screw 230 is connected to the dough conveying drive mechanism 210. The filling head 240 has a confluence channel 241, a dough injection cavity 242, and two diversion channels 243. The inlet of the confluence channel 241 connects to the internal space of the dough material box 220. The dough conveying drive mechanism... Structure 210 is used to drive the dough screw 230 to rotate, thereby driving the dough material in the dough box 220 to move towards the filling head 240. The filling cavity 242 is a cylindrical structure perpendicular to the conveying surface of the conveyor belt 110, and the outlet of the filling cavity 242 faces downward directly towards the conveying surface of the conveyor belt 110. The two ends of each diversion channel 243 are respectively connected to the confluence channel 241 and the filling cavity 242. The two diversion channels 243 are symmetrically arranged on opposite sides of the filling cavity 242, and the two diversion channels 243 are also symmetrical about the inlet central axis of the confluence channel 241. The plane containing the inlet central axis of the confluence channel 241 and the outlet central axis of the filling cavity 242 is the diversion plane. The two diversion channels 243 are symmetrical about the diversion plane.

[0040] The filling assembly 300 includes a filling drive mechanism 310, a filling screw 320, a filling hopper 330, and a filling nozzle 340. The filling drive mechanism 310 and the filling hopper 330 are both connected to the frame 100. The shaft of the filling screw 320 is rotatably connected inside the filling hopper 330, and the shaft of the filling screw 320 is perpendicular to the conveying surface of the conveyor belt 110. The filling screw 320 is connected to the filling drive mechanism 310, and the filling nozzle 340 is connected to the bottom of the filling hopper 330. The filling drive mechanism 310 uses... The filling screw 320 rotates, which in turn drives the filling in the filling hopper 330 to move towards the filling nozzle 340. The filling nozzle 340 is located at the center of the dough filling cavity 242 and is coaxially arranged with the dough filling cavity 242. There is a uniform gap between the filling nozzle 340 and the cavity wall of the dough filling cavity 242. The outlet of the filling nozzle 340 is located above the outlet of the dough filling cavity 242 to ensure that the dough in the dough filling cavity 242 can be wrapped around the outlet of the filling nozzle 340, thereby completing the filling action.

[0041] During operation, dough blanks are fed into the dough hopper 220 manually or mechanically, and fillings are fed into the filling hopper 330 to complete the material preparation. The dough conveying drive mechanism 210 drives the dough screw 230 to rotate and drives the dough blanks in the dough hopper 220 to move towards the confluence channel 241. Under the pushing action of the dough screw 230, the dough blanks enter the two diversion channels 243 from the confluence channel 241. The two diversion channels 243 guide the dough blanks to a uniform conveying channel. The dough is fed into the filling cavity 242, where the dough is conveyed with high uniformity. Under the action of extrusion and gravity, the dough moves downward and surrounds the outlet of the filling nozzle 340 to form a food dough sheet. The filling drive mechanism 310 drives the filling screw 320 to rotate and drives the filling in the filling hopper 330 to move towards the filling nozzle 340. Under the pushing action of the filling screw 320, the filling is injected from the outlet of the filling nozzle 340 into the center of the food dough sheet, thus completing the filling.

[0042] The dough material in the dough material box 220 is conveyed to the confluence channel 241 by the dough screw 230. Two branch channels 243 are symmetrical about the inlet axis of the confluence channel 241, ensuring that the dough material is evenly distributed and input into the two branch channels 243. The two branch channels 243 are also symmetrically arranged on opposite sides of the dough filling cavity 242. The two branch channels 243 can inject the dough material from opposite sides of the dough filling cavity 242 with a consistent flow rate. In a plane parallel to the horizontal plane, the dough material flows in opposite directions and converges in the dough filling cavity 242, filling the internal space of the dough filling cavity 242 through horizontal movement. This avoids large areas of voids in the dough material in the dough filling cavity 242, effectively improving the integrity of the dough filling and enhancing the consistency of the dough thickness when used for filling. It prevents the dough from being too thin or too thick in some areas, effectively improving the filling effect. Compared to... In some technologies, the dough filling technique is used on one side. This food filling device can shorten the filling stroke of the dough by a factor of two, which not only effectively improves the filling efficiency but also effectively reduces the impact of gravity on the filling effect. It can effectively ensure that the dough can be fully filled in all positions of the filling cavity 242, and the filling effect is uniform and reliable. In addition, by wrapping the filling cavity 242 around the outlet of the filling nozzle 340, it can ensure that the dough in the filling cavity 242 surrounds the outlet of the filling nozzle 340 and forms a food dough. The filling screw 320 extrudes the filling from the filling nozzle 340 to the center of the food dough, thereby realizing the filling action. This not only ensures that the distance between the filling and the edge of the food dough is relatively uniform during filling, but also ensures high filling accuracy, good filling effect, and effectively ensures the integrity and aesthetics of the filling. It has a high degree of automation, low degree of manual intervention, high filling efficiency, high consistency of filling effect, and high quality of food products.

[0043] Understandably, the bottom of the confluence channel 241 is provided with a V-shaped diversion guide surface 244. The center of the diversion guide surface 244 is directly opposite the center of the opening of the confluence channel 241. The diversion guide surface 244 is used to guide the blank to the diversion channels 243 on both sides, which can effectively improve the stability of the blank's forward movement, reduce the resistance of the blank's forward movement, and prevent the blank from accumulating and affecting the blank's performance. The blank has good flowability.

[0044] Preferably, the diversion guide surface 244 is an inwardly concave arc-shaped surface structure, which can further reduce the resistance encountered by the billet when it moves forward and effectively improve the smoothness of billet feeding.

[0045] It is understood that the dough feeding assembly 200 also includes a dough hopper 250, the outlet of which is connected to the top of the dough container 220. Multiple dough screws 230 are provided, each rotatably connected to the dough container 220, and each dough screw 230 is connected to a dough conveying drive mechanism 210. The dough conveying drive mechanism 210 can synchronously drive multiple dough screws 230 to rotate. Preferably, the dough conveying drive mechanism 210 includes a dough conveying motor and multiple synchronous gears. Each dough screw 230 is coaxially connected to a synchronous gear, and adjacent synchronous gears are connected... The dough conveying motor is directly or through a transmission mechanism connected to one of the synchronous gears, thereby driving all the dough screws 230 to rotate. The dough material box 220 is provided with multiple partitions 221. There is a partition 221 between each pair of adjacent dough screws 230. The partitions 221 are parallel to the extension direction of the dough screws 230. Along the extension direction of the dough screws 230, the length of the partition 221 is less than the length of the dough material box 220, and the partitions 221 are located on the side of the dough material box 220 away from the confluence channel 241. The outlet of the dough hopper 250 is directly opposite the area where each partition 221 is located.

[0046] By using the partition plate 221 in conjunction with multiple dough screws 230, the chance of idling can be reduced, ensuring reliable contact between the dough and the dough screws 230, improving the uniformity of dough conveying, preventing dough accumulation, and effectively mixing and stirring the dough, thereby improving the quality of the dough conveyed to the filling and thus improving the quality of food filling processing.

[0047] It is understandable that the bottom of the filling cavity 242 is provided with a filling channel 245 in the shape of an inverted frustum. That is, the channel wall of the filling channel 245 fits the circumferential surface of the inverted frustum. The filling channel 245, which narrows downward, can form a reliable gathering effect on the dough, which can effectively improve the integrity of the dough and thus effectively improve the filling effect.

[0048] Understandably, the food filling device for balanced coating also includes a sealing assembly 400. The sealing assembly 400 includes a sealing drive mechanism 410, a cover plate 420, a base plate 421, a linkage structure, and multiple claws 430. The sealing drive mechanism 410 is connected to the frame 100. Both the base plate 421 and the cover plate 420 are annular, meaning that the center of both the base plate 421 and the cover plate 420 has a clearance hole for making way for the filled semi-finished product. The claws 430 are located between the cover plate 420 and the base plate 421, and all the claws 430 are arranged around the center of the cover plate 420. The center is evenly distributed, with the two ends of the claw 430 being the root and the claw, and the middle part located between the root and the claw. The root of each claw 430 is rotatably connected to the base plate 421, and the middle part of each claw 430 is connected to the sealing drive mechanism 410 through a linkage structure. The sealing drive mechanism 410 is used to drive all claws 430 to move synchronously through the linkage mechanism, so that the claws of the claws 430 move synchronously closer to or away from the center of the cover plate 420, thereby sealing and cutting the filled semi-finished product, or making way for the output of the subsequent filled semi-finished product.

[0049] It is understood that the linkage structure includes a driving wheel 440, a driven wheel 441, a swing arm 450, a linkage wheel 460, and a synchronization ring 470. The driving wheel 440 is connected to the sealing drive mechanism 410, which can be a sealing motor. The sealing motor can be directly connected to the driving wheel 440 through a reduction gear set. The driven wheel 441 is eccentrically connected to the driving wheel 440, that is, the axis of the driven wheel 441 is eccentrically set with the axis of the driving wheel 440. One end of the swing arm 450 is provided with a first elongated slot. 451, driven wheel 441 is slidably connected to the first long slot 451, the upper and lower ends of linkage wheel 460 are rotatably connected to the other end of swing arm 450 and synchronization ring 470 respectively, the base plate 421 is provided with a second long slot 422, linkage wheel 460 is also slidably connected to the second long slot 422, synchronization ring 470 is rotatably connected to the base plate 421, synchronization ring 470 is provided with a third long slot 471, and each pawl 430 is provided with a toggle shaft 431 slidably connected to the third long slot 471 in the middle.

[0050] During operation, the lifting drive mechanism 490 drives the driving wheel 440 to rotate, and the driven wheel 441 rotates around its own axis and revolves around the axis of the driving wheel 440. In conjunction with the first elongated slot 451, the swing arm 450 swings. Furthermore, under the action of the second elongated slot 422 and the linkage wheel 460, the synchronizing ring 470 rotates. In conjunction with the third elongated slot 471 and the actuating shaft 431, this drives the pawls 430 to rotate around their root axis, causing the pawls of each pawl 430 to move closer or further apart, thus achieving a sealing or releasing action. A single sealing drive mechanism 410, through a linkage structure, can drive multiple pawls 430 to move synchronously, thereby achieving sealing or releasing actions, effectively saving on the investment cost of the drive mechanism.

[0051] Understandably, the sealing assembly 400 also includes an oil storage box 480. The oil storage box 480 is annular and connected to the inner ring of the cover plate 420. The center of the annular oil storage box 480 can make way for the output of the stuffed semi-finished product. The bottom of the oil storage box 480 is provided with several evenly distributed oil supply holes 481. The horizontal projection of all the oil supply holes 481 is located in the horizontal projection of the movement trajectory of the claws of all the claws 430, which can effectively ensure that the edible oil in the oil storage box 480 can reach the claws of the claws 430 for lubrication through the oil supply holes 481.

[0052] When the claw 430 seals and cuts the filled semi-finished product, the edible oil lubricates the claw, effectively preventing unnecessary adhesion between the claw and the filled semi-finished product, thus improving the sealing and cutting effect and enhancing the reliability of the filling action. Preferably, the oil storage box 480 is equipped with oil storage cotton to effectively control the flow rate of edible oil output from the oil supply hole 481.

[0053] It is understood that the sealing assembly 400 also includes a lifting drive mechanism 490 and a lifting bracket 491. The lifting drive mechanism 490 is connected to the frame 100, the lifting bracket 491 is connected to the lifting drive mechanism 490, and the cover plate 420 and the bottom plate 421 are both connected to the lifting bracket 491.

[0054] The lifting drive mechanism 490 is used to drive the lifting bracket 491 to lift, thereby driving the cover plate 420, the bottom plate 421 and multiple claws 430 to lift. It can realize the complete sealing and cutting action, improve the reliability of the filling action, and can reliably give way to the conveyor belt 110's conveying action.

[0055] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
