Description

A cake filling device Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a cake filling device. Background Technology

[0002] Traditional bread and cakes are popular, convenient, and quick foods. Generally, these traditional foods don't have fillings. For example, common bread is often sliced ​​and filled with meat or vegetables to make sandwiches, and cakes are even rarer. Cake production often involves multiple steps. Currently, these steps are performed separately, requiring manual labor, resulting in low efficiency and high production costs. Furthermore, some steps are done by hand; filling the cake requires manual insertion, hindering mass production. Additionally, some cake fillings are quite viscous and difficult to break, necessitating manual cutting, which is time-consuming, labor-intensive, and requires high precision to avoid overflowing or insufficient filling leading to a poor texture.

[0009] As a further improvement of the present invention, the filling assembly includes at least one filling nozzle disposed on the side of the upper mounting plate away from the lifting drive assembly. The upper end of the filling nozzle has a feed port and the lower end of the filling nozzle has a discharge port. A fixing plate is formed in the middle of the filling nozzle and the fixing plate is fixed to the lower surface of the upper mounting plate away from the lifting drive assembly.

When the cake mold reaches directly below the filling assembly, the filling enters the filling assembly from an external pump. After the filling assembly extrudes the filling to a certain length, the lifting drive assembly activates, driving the lower mounting plate to move the entire rotating drive assembly downwards. This lowers the rotating drive assembly to approach the extruded filling and the cake mold. Then, the rotating cylinder activates, driving the rotating drive structure towards the filling assembly. This causes the shearing structure on the rotating drive structure to cut the extruded filling, ensuring it is precisely injected into the cake batter in the cake mold, thus completing the cake filling process. The entire process is highly automated, requiring no manual labor, saving time and effort. It also precisely cuts the cake filling and accurately injects it into the cake mold, ensuring a high yield rate.

[0021] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the specific implementation of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0022] In the description of this invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Referring to Figures 1 to 3, this embodiment of the invention provides a cake filling device, including an upper mounting plate 1, a lifting drive assembly 2 disposed above one side of the upper mounting plate 1, a rotary drive assembly 3 disposed below and connected to the lifting drive assembly 2, and a filling assembly 4 disposed on the other side of the upper mounting plate 1; the rotary drive assembly 3 includes a rotary cylinder 31 disposed below the lifting drive assembly 2, a lower mounting plate 32 that is generally I-shaped and whose upper end is connected to the lifting drive assembly 2, a rotary drive structure 33 disposed on the output shaft of the rotary cylinder 31, and a shearing structure 34 disposed on the side of the rotary drive structure 33 near the filling assembly 4 and located below the filling assembly 4.

[0026] When the cake mold reaches directly below the filling assembly 4, the filling enters the filling assembly 4 from an external pump. After the filling assembly 4 extrudes the filling to a certain length, the lifting drive assembly 2 is activated, driving the lower mounting plate 32 to move the entire rotating drive assembly 3 downwards. This lowers the rotating drive assembly 3 to approach the extruded filling and the cake mold. Then, the rotating cylinder 31 is activated, driving the rotating drive structure 33 towards the filling assembly. This causes the shearing structure 34 on the rotating drive structure 33 to cut the extruded filling, ensuring it is precisely injected into the cake batter in the cake mold, thus completing the cake filling process. The entire process is highly automated, requiring no manual labor, saving time and effort. It can precisely cut the cake filling and accurately inject it into the cake mold, ensuring a high yield rate. The length of the filling can be set according to actual conditions, so no specific limitation is made in this embodiment.

[0027] As shown in Figure 3, the specific structural configuration of the rotary drive structure 33 includes a first transmission wheel 331 disposed on the rotary cylinder 31, a first shaft 332 disposed on the upper part of the lower mounting plate 32 near the rotary cylinder 31, at least one first bearing 333 rotatably disposed on the first shaft 332, a second shaft 334 disposed on the lower part of the lower mounting plate 32 near the rotary cylinder 31, at least one second bearing 335 rotatably disposed on the second shaft 334, a first drive cutting plate 336 disposed between the first transmission wheel 331 and the first bearing 333, and a second drive cutting plate 337 disposed between the first transmission wheel 331 and the second bearing 335.

[0028] When the rotary cylinder 31 is started, it drives the first transmission wheel 331 to rotate. Since the first driving cutting plate 336 is clamped between the first transmission wheel 331 and the first bearing 333, and the second driving cutting plate 337 is clamped between the first transmission wheel 331 and the second bearing 335, the first transmission wheel 331 drives the first driving cutting plate 336 to push towards the filling assembly 4 while rotating, and the second driving cutting plate 337 is pulled back towards the lifting drive assembly 2. This causes the shearing mechanism to cut the filling that has been squeezed out on the filling assembly 4, so that the filling is injected into the cake batter of the cake mold, thus completing the purpose of cake battering. When the rotary cylinder 31 rotates, the first transmission wheel 331 rotates simultaneously, driving the first driving cutter 336 to pull back towards the lifting drive assembly 2, while the second driving cutter 337 pushes towards the filling direction. This causes the shearing mechanism to cut the filling extruded from the filling assembly 4 again, ensuring the filling is precisely injected into the cake batter in the cake mold, completing the cake filling. The two shearing methods work in an alternating manner, further improving the filling efficiency of this device. The first bearing 333 presses against the first driving cutter 336 and is driven by the first driving cutter 336, thereby limiting the first driving cutter 336, preventing it from shifting, and ensuring that the first driving cutter 336 precisely drives the shearing structure 34, improving the accuracy of this device. The second bearing 335 presses against the second drive cutting plate 337 and is driven by the second drive cutting plate 337, thereby limiting the second drive cutting plate 337, preventing the second drive cutting plate 337 from shifting, and enabling the second drive cutting plate 337 to accurately drive the shearing structure 34, further improving the accuracy of the device.

[0029] The total width of the first bearing 333 and the second bearing 335 should match the total width of the first drive wheel 331, so as to better limit the second drive cutting plate 337 and the first drive cutting plate 336.

[0030] To prevent the first bearing 333 and the second bearing 335 from shifting during operation, a first three-axis positioning plate 338 is vertically arranged between the outermost edge of the first shaft 332 and the outermost edge of the second shaft 334, as shown in Figure 3. The first three-axis positioning plate 338 restricts the first bearing 333 between the first shaft 332 and the first three-axis positioning plate 338, and restricts the second bearing 335 between the second shaft 334 and the first three-axis positioning plate 338, effectively preventing the first bearing 333 and the second bearing 335 from shifting during operation.

[0031] To further prevent the rotation drive structure 33 from shifting, as shown in Figure 3, the rotation drive assembly 3 includes a limiting driven rotation structure 35. The limiting driven rotation structure 35 includes a third shaft 351 fixed to the upper part of the lower mounting plate 32 on the side away from the rotary cylinder 31, at least one third bearing 352 rotatably mounted on the third shaft 351, a fourth shaft 353 disposed on the lower part of the lower mounting plate 32 on the side away from the rotary cylinder 31, and at least one third bearing 352 rotatably mounted on the fourth shaft 353. The system includes at least one fourth bearing 354, at least one fourth bearing 354 rotatably mounted on the fourth shaft 353, a fifth shaft 355 disposed in the middle of the side of the lower mounting plate 32 away from the rotary cylinder 31, a fifth bearing 356 rotatably mounted between the first drive cutting plate 336 and the second drive cutting plate 337 and rotatably mounted on the fifth shaft 355, and a second three-axis positioning plate 357 disposed on the outermost side of the third shaft 351, the outermost side of the fourth shaft 353 and the outermost side of the fifth shaft 355.

[0032] When the rotary cylinder 31 is activated, the first driving cutting plate 336 is pushed towards the filling assembly 4, and the second driving cutting plate 337 is pulled back towards the lifting drive assembly 2. Since the third bearing 352 presses against the other side of the first driving cutting plate 336, the fourth bearing 354 presses against the other side of the second driving cutting plate 337, and the fifth bearing 356 rotates between the first driving cutting plate 336 and the second driving cutting plate 337, the first driving cutting plate 336 is clamped and its travel is limited by the third bearing 352 and the fifth bearing 356, and the second driving cutting plate 337 is clamped and its travel is limited by the fourth bearing 354 and the fifth bearing 356, thereby further improving the accuracy of the device in cutting the filling.

[0033] As shown in Figures 1 and 2, the filling assembly 4 includes at least one filling nozzle disposed on the side of the upper mounting plate 1 away from the lifting drive assembly 2. The upper end of the filling nozzle has a feed inlet, and the lower end has a discharge outlet. A fixing plate is formed in the middle of the filling nozzle and is fixed to the lower surface of the upper mounting plate 1 on the side away from the lifting drive assembly 2, thereby fixing the filling nozzle to the upper mounting plate 1. Filling material enters the filling nozzle from an external pump through the feed inlet and is extruded through the discharge outlet. The shape of the discharge outlet can be set according to actual conditions, such as square or circular, and therefore no specific limitation is made in this embodiment.

[0034] Preferably, to improve the filling efficiency of this device, as shown in Figures 1 and 2, there are two filling nozzles, namely a first filling nozzle 41 and a second filling nozzle 42. The first filling nozzle 41 has a first inlet 411 at its upper end and a first outlet 412 at its lower end. A first fixing plate 413 is formed in the middle of the first filling nozzle 41 and is fixed to the inner side of the lower surface of the upper mounting plate 1 away from the lifting drive assembly 2. The second filling nozzle 42 has a second inlet 421 at its upper end and a second outlet 422 at its lower end. A second fixing plate 423 is formed in the middle of the second filling nozzle 42 and is fixed to the outer side of the lower surface of the upper mounting plate 1 away from the lifting drive assembly 2. The first filling nozzle 41 and the second filling nozzle 42 operate synchronously, so that the two sets of fillings are squeezed out at the same time and cut by the shearing structure 34, respectively entering the two sets of cake molds, thereby improving the filling efficiency of this device.

[0035] As shown in Figures 1 and 2, the shearing structure 34 includes an upper cutting plate 341 disposed on the side of the first driving cutting plate 336 away from the lifting drive assembly 2, a lower cutting plate 342 disposed on the side of the second driving cutting plate 337 away from the lifting drive assembly 2, at least one cutting plate fixing block 343 disposed between the upper cutting plate 341 and the lower cutting plate 342, a first cutting rod 344 disposed on the lower end surface of the upper cutting plate 341 away from the first driving cutting plate 336, a second cutting rod 345 disposed on the lower end surface of the lower cutting plate 342 away from the second driving cutting plate 337, a third cutting rod 346 disposed on the lower end surface of the cutting plate fixing block 343 near the second driving cutting plate 337, and a fourth cutting rod 347 disposed on the lower end surface of the lower cutting plate 342 near the second driving cutting plate 337. The upper cutting plate 341 and the lower cutting plate 342 are staggered.

[0036] When the first driving cutting plate 336 pushes and the second driving cutting plate 337 retracts, the upper cutting plate 341, positioned on the first driving cutting plate 336, is pushed outward by the first driving cutting plate 336. The cutting plate fixing block 343 and the third cutting rod 346, both positioned on the upper cutting plate 341, are simultaneously pushed out. The third cutting rod 346 on the cutting plate fixing block 343 extrudes the filling from the first discharge port 412 of the first filling nozzle 41. The cake filling is cut off, causing the cake filling squeezed out from the first outlet 412 of the first filling nozzle 41 to fall into the cake mold located directly below the first filling nozzle 41, thus completing the filling of the cake. Simultaneously, the first cutting rod 344 set on the upper cutting plate 341 is pushed outward to cut off the cake filling squeezed out from the second outlet 422 of the second filling nozzle 42, causing the cake filling from the second outlet 422 of the second filling nozzle 42 to fall into the cake mold located directly below the second filling nozzle 42, thus completing the filling of the cake.

[0037] The lower cutting plate 342 is mounted on the second driving cutting plate 337, and is thus driven by the second driving cutting plate 337 to retract toward the rotary cylinder 31. The second cutting rod 345, mounted on the lower section of the lower cutting plate 342 away from the second driving cutting plate 337, moves toward the rotary cylinder 31. The second cutting rod 345 on the lower cutting plate 342 cuts the cake filling extruded from the second outlet 422 of the second filling nozzle 42, causing the cake filling extruded from the second outlet 422 of the second filling nozzle 42 to fall onto the cylinder 31. The filling of the cake is completed in the cake mold directly below the first filling nozzle 42. The fourth cutting rod 347, which is set on the lower end face of the lower cutting plate 342 near the second driving cutting plate 337, moves toward the rotating cylinder 31. The fourth cutting rod 347 on the lower cutting plate 342 cuts the cake filling squeezed out of the first outlet 412 of the first filling nozzle 41, so that the cake filling squeezed out from the first outlet 412 of the first filling nozzle 41 falls into the cake mold located directly below the first filling nozzle 41, thus completing the filling of the cake.

[0038] Regarding the order in which the first cutting rod 344 and the second cutting rod 345 cut the second filling nozzle 42 and the length of the cake filling, the lengths of the first driving cutting plate 336 and the second driving cutting plate 337 can be adjusted according to the actual situation. This allows the first driving cutting plate 336 to influence the time when the first cutting rod 344 cuts the cake filling and the second driving cutting plate 337 to influence the time when the second cutting rod 345 cuts the cake filling. As a result, the first cutting rod 344 and the second cutting rod 345 cut the cake filling alternately, thereby controlling the length of the cake filling and improving the accuracy of cutting the cake filling.

[0039] Regarding the use of the first cutting rod 344 and the second cutting rod 345, either a single first cutting rod 344 or a single second cutting rod 345 can be used, or both can be used together, depending on actual needs.

[0040] Regarding the order in which the third cutting rod 346 and the fourth cutting rod 347 cut the first filling nozzle 41 and the length of the cake filling, the lengths of the first driving cutting plate 336 and the second driving cutting plate 337 can be adjusted according to the actual situation. This allows the first driving cutting plate 336 to influence the time when the third cutting rod 346 cuts the cake filling, and the second driving cutting plate 337 to influence the time when the fourth cutting rod 347 cuts the cake filling. As a result, the third cutting rod 346 and the fourth cutting rod 347 cut the cake filling alternately, thereby controlling the length of the cake filling and improving the accuracy of cutting the cake filling.

[0041] Regarding the use of the third cutting rod 346 and the fourth cutting rod 347, either a single third cutting rod 346 or a single fourth cutting rod 347 can be used, or both can be used together, depending on the actual situation.

[0042] Similarly, when the first driving cutting plate 336 retracts and the second driving cutting plate 337 extends, the first driving cutting plate 336 causes the upper cutting plate 341 to retract. The cutting plate fixing block 343 and the third cutting rod 346 on the cutting plate fixing block 343 retract synchronously. The third cutting rod 346 on the cutting plate fixing block 343 cuts off the cake filling squeezed out of the first outlet 412 of the first filling nozzle 41, so that the cake filling squeezed out of the first outlet 412 of the first filling nozzle 41 falls into the cake mold directly below the first filling nozzle 41, completing the filling. The first cutting rod 344, which is set on the upper cutting plate 341, retracts synchronously toward the rotating cylinder 31, thereby cutting off the cake filling squeezed out of the second outlet 422 of the second filling nozzle 42. The cake filling from the second outlet 422 of the second filling nozzle 42 falls into the cake mold located directly below the second filling nozzle 42, thus completing the filling of the cake.

[0043] The lower cutting plate 342 is mounted on the second driving cutting plate 337, and is thus driven outward by the second driving cutting plate 337. The second cutting rod 345 mounted on the lower cutting plate 342 retracts, cutting off the cake filling extruded from the second outlet 422 of the second filling nozzle 42, causing the cake filling extruded from the second outlet 422 of the second filling nozzle 42 to fall into the cake mold located directly below the second filling nozzle 42, completing the filling of the cake. The fourth cutting rod 347 mounted on the lower cutting plate 342 pushes outward, cutting off the cake filling extruded from the first outlet 412 of the first filling nozzle 41, causing the cake filling extruded from the first outlet 412 of the first filling nozzle to fall into the cake mold located directly below the first filling nozzle 41, completing the filling of the cake.

[0044] The first driving cutting plate 336 and the second driving cutting plate 337 can each drive the shearing mechanism on them to operate once, thereby speeding up the shearing efficiency and further improving the production speed.

[0045] As shown in Figures 1 and 2, the upper cutting plate 341 comprises an upper main plate 3411 that is generally hollow and rectangular, an upper fixing block 3412 formed on the upper main plate 3411 facing the first driving cutting plate 336 and protruding upward, and a lower fixing block 3413 formed on the upper main plate 3411 away from the first driving cutting plate 336 and extending downward. The first cutting rod 344 is disposed on the lower surface of the lower fixing block 3413 near the lifting drive assembly 2, so that the first cutting rod 344 is located below the second filling nozzle 42, which facilitates the cutting of cake filling squeezed out from the second outlet 422 of the second filling nozzle 42. The upper fixing block 3412 is fixed to the side of the first driving cutting plate 336, so that the first driving cutting plate 336 can drive the upper cutting plate 341 to move laterally as a whole. The downward-extending structure of the lower fixing block 3413 is used to limit the travel of the lower cutting plate 342, preventing the lower cutting plate 342 from moving excessively and falling off when driven by the second driving cutting plate 337, thereby improving the accuracy of the device. The upper end of the cutting plate fixing block 343 is disposed between the upper main plate 3411.

[0046] As shown in Figures 1 and 2, the lower cutting plate 342 includes a lower main plate 3421 that is hollow in shape, a lower slot 3422 on the lower part of the lower main plate 3421 away from the second driving cutting plate 337, a second cutting rod 345 on the outer side of the lower slot 3422, and a fourth cutting rod 347 on the lower inner lower edge of the lower slot 3422 near the second driving cutting plate 337. This allows the second cutting rod 345 to be positioned below the second filling nozzle 42 and cut the cake filling squeezed out from the second outlet 422 of the second filling nozzle 42, and the fourth cutting rod 347 to be positioned below the first filling nozzle 41 and cut the cake filling squeezed out from the first outlet 412 of the first filling nozzle 41. The second driving cutting plate 337 is fixed on the side wall of the lower main plate 3421 near the rotary cylinder 31. The lower end of the cutting plate fixing block 343 moves between the lower slots 3422, so that the cutting plate fixing block 343 can limit the movement stroke of the lower cutting block while the upper cutting plate 341 and the lower cutting plate 342 are moving, preventing the lower cutting plate 342 from shifting or falling off, and improving the accuracy of the device.

[0047] As shown in Figures 1 to 3, the specific structural configuration of the lifting drive assembly 2 includes a lifting cylinder 21 mounted on the upper mounting plate 1 with its output axis extending downward to the upper end face of the lower mounting plate 32, and a lifting guide column 22 respectively mounted on both sides of the lifting cylinder 21 and passing through the upper end faces of the upper mounting plate 1 and the lower mounting plate 32. The lifting cylinder 21 drives the lower mounting plate 32 to move up and down, thereby driving the entire rotary drive assembly 3 to move up and down. By controlling the lifting cylinder 21 to adjust the height position of the rotary drive assembly 3, the height of the shearing structure 34 can be adjusted, thereby controlling the length of the cake filling extruded from the filling assembly 4. This makes the device suitable for cake making needs that require cake fillings of different lengths and sizes, further improving the practicality of the device and expanding its application range. By providing lifting guide columns 22 on the sides of the lifting cylinder 21, the lifting cylinder 21 is restricted in its stroke by the lifting guide columns 22 when it drives the lower mounting plate 32, thereby preventing displacement and improving the operational accuracy of the device.

[0048] To further improve the stability of the vertical movement of the rotary drive assembly 3, as shown in Figures 1 to 3, the device may further include a lifting and limiting drive assembly 5 disposed under the lower mounting plate 32. The lifting and limiting drive assembly 5 includes a lifting and limiting mounting plate 53, a lifting and limiting cylinder 51 disposed on the lifting and limiting mounting plate 53 with its output shaft extending upwards to the lower end face of the lower mounting plate 32, and a lifting and limiting guide post 52 disposed on both sides of the lifting and limiting cylinder 51 and passing through the lifting and limiting mounting plate 53 to connect with the lower end face of the lower mounting plate 32. When the lifting cylinder 21 drives the rotary drive assembly 3 to move vertically, the lifting and limiting cylinder 51 simultaneously drives the rotary drive assembly 3 accordingly. For example, when the lifting cylinder 21 drives the rotary drive assembly 3 to move downwards, the output shaft of the lifting and limiting cylinder 51 retracts simultaneously, so that the downward movement of the rotary drive assembly 3 is simultaneously driven by both the lifting cylinder 21 and the lifting and limiting cylinder 51, resulting in more stable movement. By setting lifting limit guide posts 52 on both sides of the lifting limit cylinder 51, the lifting limit cylinder 51 is restricted in its stroke by the lifting limit guide posts 52 when it drives the lower mounting plate 32, thereby preventing displacement and further improving the operating accuracy of the device.
