Description

Technical Field

[0001] This invention relates to the field of rice ball making technology, and in particular to a multi-flavor rice ball making apparatus and method. Background Technology

[0002] Rice balls are a convenient food that is widely welcomed by consumers. When making them, the prepared ingredients are mixed together, and a certain amount of the mixture needs to be manually scooped out and repeatedly kneaded by hand until it forms a certain shape. The traditional way of making rice balls by hand is not only inefficient, but also makes it difficult to ensure the uniformity of the rice balls in terms of shape and weight.

[0003] To overcome the shortcomings of handmade production, various rice ball forming molds have appeared on the market. Although these molds can unify the shape of the rice balls, there are difficulties in the demolding process. The rice material itself has strong stickiness, and after being compacted and shaped, the rice balls are very easy to stick to the inner wall of the mold, especially the side wall of the mold.

[0004] Existing demolding methods rely on a bottom pusher plate to push the rice ball upwards, or to invert the mold as a whole. The upward pushing force from the bottom can easily cause the rice ball structure to deform or break. The inverted method results in incomplete demolding, and rice residue will stick to the inside of the mold, making mold cleaning cumbersome and affecting the efficiency of continuous production.

[0005] Furthermore, when making multi-flavored rice balls, it is difficult for operators to accurately fill the center of the liquid filling. Often, it is necessary to manually pre-make holes in the rice before filling. The filling process is not only cumbersome, but also prone to cross-contamination. At the same time, the existing equipment is not capable of making multiple different flavored rice balls on the same machine at the same time, which limits the flexibility of production. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-flavor rice ball making device and method, which solves the problems of rice balls sticking to the mold sidewalls due to the stickiness of rice after molding, making demolding difficult, the finished product easily damaged and deformed, as well as the tedious mold cleaning and the difficulty in accurately injecting the fluid filling into the center of the rice ball, making it impossible to efficiently and simultaneously produce multiple different flavor rice balls in a single operation.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a multi-flavor rice ball making device, including a fixed base, a lower mold is provided on the top of the fixed base, an installation platform is provided above the lower mold, a plurality of upper molds are provided inside the installation platform, and an extrusion discharge component is provided inside the upper mold;

[0008] The extrusion discharge assembly includes a discharge pipe with multiple discharge holes at the bottom of its outer periphery. A limit plate is fixedly connected to the outside of the discharge pipe. A second compression spring is sleeved on the top of the outer periphery of the discharge pipe. A first extrusion plate is installed on the top of the discharge pipe. A compression rod is slidably connected inside the discharge pipe. Multiple sealing rings are provided at the bottom of the outer periphery of the compression rod. A second extrusion plate is installed on the top of the compression rod.

[0009] The fixed base is equipped with fixing components on both the front and rear sides to fix the position of the lower mold and prevent it from loosening. The installation platform is equipped with limit components on both the left and right sides inside to fix the current position of the installation platform.

[0010] Preferably, the top of the fixed base is fixedly connected with multiple limiting lifting rods, and multiple limiting slots are opened on the outer side of the limiting lifting rods. The limiting component includes a first compression spring and a limiting strip. Telescopic movable slots are opened on both the left and right sides of the installation platform. The limiting strip is slidably arranged in the telescopic movable slot. The first compression spring is arranged in the telescopic movable slot. One end of the first compression spring abuts against the inner side wall of the telescopic movable slot, and the other end abuts against the limiting strip. A toggle rod is provided at the end of the limiting strip near the first compression spring. The front end of the limiting strip is slidably connected in the limiting slot.

[0011] Preferably, the fixing component includes a hook base, which is fixedly connected to the front and rear sides of the lower mold. Two support blocks are fixedly connected to both the front and rear sides of the fixing base. A rotating shaft is fixedly connected to one side of the two support blocks facing each other. An operating handle is rotatably connected to the outside of the rotating shaft. A connecting buckle is rotatably connected inside the operating handle. The connecting buckle is sleeved on the outside of the hook base.

[0012] Preferably, the fixed base is fixedly connected to support legs on both the left and right sides of its bottom, and the lower mold and the mounting platform are fixedly connected to lifting handles on both the left and right sides.

[0013] Preferably, the lower mold and the edge of the mounting platform are provided with multiple lifting holes, and the limiting lifting rod is slidably connected in the lifting holes.

[0014] Preferably, the upper mold is provided with a mold cover at the top, the limiting plate abuts against the bottom side of the mold cover, and the discharge pipe passes through the top of the mold cover.

[0015] Preferably, a scraping disc is fixedly connected to the bottom of the upper mold, and a telescopic hole is opened at the bottom of the upper mold, with the front end of the discharge pipe slidably connected inside the telescopic hole.

[0016] Preferably, one end of the second compression spring is fixedly connected to the bottom of the first extrusion plate, and the other end of the second compression spring is fixedly connected to the top of the mold cover.

[0017] Preferably, the lower mold has multiple shaping grooves on its top, and the upper mold has the same shape as the shaping grooves.

[0018] A preferred method for making multi-flavored rice balls includes the following steps:

[0019] S1: According to the production requirements, different types of liquid fillings are injected into multiple upper molds on the installation platform, so that the liquid fillings flow into and fill the internal storage space of the discharge pipe, preparing for the production of multiple flavors;

[0020] S2: Place the lower mold on the fixed base, so that the limit lifting rod passes through the lifting hole on the edge of the lower mold. Then operate the fixing component to lock and fix the lower mold on the fixed base. Next, evenly fill the multiple shaping grooves of the lower mold with rice as the base of the rice ball.

[0021] S3: Next, hold the lifting handles on both sides of the installation platform and press down on the installation platform to make it move the upper mold smoothly down along the limit lifting rod into the shaping groove of the lower mold, compacting the rice into shape. When the predetermined compaction position is reached, the limit component is triggered, so that the limit strip is engaged in the limit groove corresponding to the limit lifting rod, locking the installation platform and the upper mold in the current compaction position.

[0022] S4: With the installation platform locked in position, press down on the first extrusion plate to make the discharge pipe go down and insert into the center of the compacted rice ball. Then press down on the second extrusion plate to drive the compression rod down and squeeze the fluid filling that has flowed into the discharge pipe in S1 into the rice ball through the discharge hole.

[0023] S5: Keep the installation platform and upper mold in the pressing and locking state of the rice ball unchanged in S3. Operate the fixing component to release the locking connection between the lower mold and the fixed base. Hold the lifting handle of the lower mold and lift the entire lower mold vertically upward. During the lifting of the lower mold, since the upper mold is locked and kept stationary by the limiting component, the scraping plate at the bottom of the upper mold performs relative scraping motion on the inner wall of the shaping groove, causing the rice ball to separate from the side wall of the lower mold. After the lower mold is completely separated from the rice ball, the shaped and filled rice ball is retained on the surface of the fixed base.

[0024] S6: Then operate the lever of the limit component to release the lock of the installation platform, lift the installation platform upward to reset the upper mold, and finally take the finished multi-flavor rice ball from the fixed base.

[0025] In summary, the present invention has at least one of the following beneficial technical effects:

[0026] 1. This invention solves the problem of sticky rice being difficult to demold completely by setting a demolding structure that combines a limiting component with a scraping plate. During the demolding process, the limiting component locks the upper mold at a fixed height, making the upper mold act as a reverse pressing component. When the operator pulls the lower mold upward, the formed rice ball is forced to remain on the surface of the fixed base, avoiding the squeezing and deformation of the rice ball caused by the traditional bottom ejection method. At the same time, the scraping plate and the inner wall of the upward-moving lower mold generate a relative scraping motion, which can automatically scrape off the sticky rice starch layer remaining on the inner wall of the shaping groove. While ensuring that the surface of the rice ball is smooth and flat, the cleaning frequency of the mold is reduced.

[0027] 2. This invention achieves a center-point filling function without the need for pre-drilling by using an extrusion and discharge assembly. The first extrusion plate drives the discharge tube to be inserted into the rice ball to form an injection channel, and then the second extrusion plate pushes the compression rod to accurately inject the pre-stored fluid filling into the center of the rice ball. This step-by-step action avoids filling overflow or rice structure collapse. In addition, since the extrusion and discharge assembly inside each upper mold has an independent storage space, the operator can place different types of fillings into different upper molds in the same batch, thereby achieving the simultaneous production of multiple flavors of rice balls in a single forming operation, improving production efficiency and the ability to produce multiple flavors of rice balls.

[0028] 3. This invention enhances the structural stability of the device during the molding and demolding process through the mechanical cooperation of the fixing components and the limiting slots. The fixing components on both sides of the fixed base can provide strong pre-tightening force to ensure that the lower mold maintains a rigid connection with the base during the pressing and filling process, preventing the rice ball shape deviation caused by the misalignment of the lower mold. In addition, with the multi-position limiting slots, the pressing depth of the installation platform can be flexibly locked according to the amount of rice filling, ensuring that the rice balls produced in batches maintain a high degree of consistency in height, density and specifications, meeting the requirements of standardized production.

[0039] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 The present invention will be further described in detail below.

[0040] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 9 The present invention provides a multi-flavor rice ball making device, including a fixed base 1, a lower mold 5 is provided on the top of the fixed base 1, an installation platform 10 is provided above the lower mold 5, a plurality of upper molds 11 are provided inside the installation platform 10, and an extrusion discharge component 16 is provided inside the upper mold 11.

[0041] Specifically, the fixed base 1 serves as a supporting structure for the entire process of making multi-flavor rice balls. The rice is compacted in batches through the mounting platform 10, and the extrusion component 16 performs filling after compaction. The lower mold 5 and the upper mold 11 work together to determine the shape of the rice ball.

[0042] The extrusion discharge assembly 16 includes a discharge pipe 161, with multiple discharge holes 162 at the bottom of the outer periphery of the discharge pipe 161. A limit plate 163 is fixedly connected to the outer side of the discharge pipe 161. A second compression spring 164 is sleeved on the top of the outer periphery of the discharge pipe 161. A first extrusion plate 165 is installed on the top of the discharge pipe 161. A compression rod 166 is slidably connected inside the discharge pipe 161. Multiple sealing rings 167 are provided at the bottom of the outer periphery of the compression rod 166. A second extrusion plate 168 is installed on the top of the compression rod 166.

[0043] Specifically, the downward stroke of the first extrusion plate 165 of the extrusion discharge assembly 16 is controlled by the preload of the second compression spring 164. The function of the limiting plate 163 is to prevent the discharge pipe 161 from excessively popping out of the upper mold 11. The compression rod 166 slides in the discharge pipe 161. The function of the sealing ring 167 is to convert the pressing of the second extrusion plate 168 into the fluid pressure of the filling, which is discharged through the discharge hole 162.

[0044] Please see the appendix Figure 3 Appendix Figure 6 and attached Figure 7 The top of the fixed base 1 is fixedly connected with multiple limiting lifting rods 3. Multiple limiting slots 4 are opened on the outer side of the limiting lifting rods 3. Limiting components 15 are set on both the left and right sides inside the installation platform 10 to fix the current position of the installation platform 10. The limiting component 15 includes a first compression spring 152 and a limiting strip 153. Telescopic movable grooves 154 are opened on both the left and right sides of the installation platform 10. The limiting strip 153 is slidably set in the telescopic movable groove 154. The first compression spring 152 is set in the telescopic movable groove 154. One end of the first compression spring 152 abuts against the inner side wall of the telescopic movable groove 154, and the other end abuts against the limiting strip 153. A toggle rod 151 is set on the end of the limiting strip 153 near the first compression spring 152. The front end of the limiting strip 153 is slidably connected in the limiting slot 4.

[0045] Specifically, the limiting lifting rod 3 is a static guide rail and locking reference component fixed on the fixed base 1, and the limiting component 15 is a dynamic locking component installed on the installation platform 10. When the installation platform 10 moves downward, the limiting clip 153 slides against the surface of the limiting lifting rod 3. The first compression spring 152 provides a continuous thrust to the limiting clip 153 in the telescopic movable groove 154, so that the limiting clip 153 automatically embeds when it reaches the limiting slot 4. The toggle rod 151 is used to pull the limiting clip 153 in the opposite direction, thereby releasing the locking state of the limiting slot 4 and allowing the installation platform 10 to move freely.

[0046] Please see the appendix Figure 2 and attached Figure 5 The fixed base 1 has fixed components 9 on both the front and rear sides to fix the position of the lower mold 5 and prevent it from loosening. The fixed components 9 include hook seats 91, which are fixedly connected to the front and rear sides of the lower mold 5. The fixed base 1 has two support blocks 94 fixedly connected to both the front and rear sides. The two support blocks 94 are fixedly connected to a rotating shaft 95 on one side facing each other. The rotating shaft 95 is rotatably connected to an operating handle 93 on the outside. The operating handle 93 is rotatably connected to a connecting buckle 92 inside. The connecting buckle 92 is sleeved on the outside of the hook seat 91.

[0047] Specifically, the support block 94 and the rotating shaft 95 of the fixed component 9 provide a fixed rotation reference for the operating handle 93. The connecting buckle 92 rotates with the operating handle 93. The hook seat 91 is the force point designed for the lower mold 5. When the connecting buckle 92 rotates, the connecting buckle 92 will hook the hook seat 91 and press the lower mold 5 against the fixed base 1, thereby achieving the function of fixing the fixed base 1 and the lower mold 5.

[0048] Please see the appendix Figure 2 -Appendix Figure 4 The fixed base 1 has support legs 2 fixedly connected to the left and right sides of its bottom, and the lower mold 5 and the mounting platform 10 have lifting handles 8 fixedly connected to the left and right sides.

[0049] Specifically, the support leg 2 suspends the bottom surface of the fixed base 1, the lifting handle 8 facilitates the operator to apply relative force, the lifting handle 8 of the mounting platform 10 is used to apply downward pressure, and the lifting handle 8 of the lower mold 5 is used to apply upward lifting force, so that the dough placed in the lower mold 5 can be stably demolded.

[0050] Please see the appendix Figure 3 Appendix Figure 7 and attached Figure 8 Multiple lifting holes 6 are provided on the edges of both the lower mold 5 and the mounting platform 10, and the limiting lifting rod 3 is slidably connected in the lifting holes 6.

[0051] Specifically, the limit lifting rod 3 is a fixed limit guide rail used to align the lower mold 5 and the mounting platform 10, and the lifting hole 6 is a sliding hole on the lower mold 5 and the mounting platform 10 to ensure that the lower mold 5 and the mounting platform 10 can only move vertically along the axis of the limit lifting rod 3.

[0052] Please see the appendix Figure 8 and attached Figure 9 The upper mold 11 is provided with a mold cover 12 on the top, the limiting plate 163 abuts against the bottom side of the mold cover 12, and the discharge pipe 161 passes through the top of the mold cover 12.

[0053] Specifically, the mold cover 12 seals the top of the upper mold 11 and serves as the mounting base for the extrusion discharge assembly 16. The discharge pipe 161 passes through the mold cover 12, and the limiting plate 163 is fixed on the discharge pipe 161. The contact surface between the limiting plate 163 and the bottom side of the mold cover 12 forms the end point of the upward reset stroke of the discharge pipe 161, ensuring that the discharge pipe 161 remains in this position when no force is applied.

[0054] Please see the appendix Figure 8 and attached Figure 9 The bottom of the upper mold 11 is fixedly connected to a scraper plate 13, and the bottom of the upper mold 11 is provided with a telescopic hole 14, and the front end of the discharge pipe 161 is slidably connected in the telescopic hole 14.

[0055] Specifically, the scraper plate 13 is a component fixed to the bottom of the upper mold 11. Its side is sloping. The telescopic hole 14 is a movement channel reserved by the scraper plate 13 for the discharge pipe 161, allowing the discharge pipe 161 to extend along a predetermined route when it is pressed downward. The scraper plate 13 is stationary with the upper mold 11. When the lower mold 5 is lifted, the outer edge of the scraper plate 13 scrapes against the inner wall of the shaping groove 7, thereby scraping away the sticky residue in the shaping groove 7.

[0056] Please see the appendix Figure 8 and attached Figure 9 One end of the second compression spring 164 is fixedly connected to the bottom of the first extrusion plate 165, and the other end of the second compression spring 164 is fixedly connected to the top of the mold cover 12.

[0057] Specifically, the second compression spring 164 is installed between the first extrusion plate 165 and the mold cover 12. When the first extrusion plate 165 is pressed, the second compression spring 164 is compressed and stores elastic force. After the extrusion is completed and the pressure is released, the elastic force of the second compression spring 164 pushes the first extrusion plate 165 to move upward and reset.

[0058] Please see the appendix Figure 4 and attached Figure 7 The lower mold 5 has multiple shaping grooves 7 on its top, and the upper mold 11 has the same shape as the shaping grooves 7.

[0059] Specifically, the shaping groove 7 is the cavity of the lower mold 5 used to hold rice, and the upper mold 11 is the component on the mounting platform 10 used to compress rice. The shape of the upper mold 11 matches the inner cavity of the shaping groove 7. When the upper mold 11 presses the rice ball down, it enters the shaping groove 7 and compresses the rice under relative motion.

[0060] Please see the appendix Figure 1 -Appendix Figure 9 A method for making multi-flavored rice balls, including the following steps:

[0061] S1: According to the production requirements, different types of liquid fillings are injected into multiple upper molds 11 on the installation platform 10, so that the liquid fillings flow into and fill the internal storage space of the discharge pipe 161, in preparation for the production of multiple flavors.

[0062] This step is performed before the molds are pressed together. The multiple upper molds 11 on the mounting platform 10 are independent of each other. The operator can fill different fillings into the upper molds 11 to make rice balls of different flavors at the same time on the same mounting platform 10.

[0063] S2: Place the lower mold 5 on the fixed base 1, so that the limiting lifting rod 3 passes through the lifting hole 6 on the edge of the lower mold 5. Then operate the fixing component 9 to lock and fix the lower mold 5 on the fixed base 1. Next, fill the multiple shaping grooves 7 of the lower mold 5 evenly with rice as the rice ball base.

[0064] This step involves loading the rice ball base. The lower mold 5 is positioned and installed by the lifting hole 6 and the limiting lifting rod 3. The fixing component 9 locks the lower mold 5 on the fixing base 1 to prevent the lower mold 5 from shifting when under pressure. Then, the rice is filled into the shaping groove 7.

[0065] S3: Next, hold the lifting handles 8 on both sides of the installation platform 10 and press down on the installation platform 10 so that it drives the upper mold 11 to descend smoothly along the limit lifting rod 3 and enter the shaping groove 7 of the lower mold 5 to compact the rice. When the predetermined compaction position is reached, the limit component 15 is triggered so that the limit strip 153 is engaged in the limit groove 4 corresponding to the limit lifting rod 3, locking the installation platform 10 and the upper mold 11 in the current compaction position.

[0066] This step applies pressure by lifting handle 8, and the installation platform 10 moves downward along the limit lifting rod 3. The upper mold 11 enters the shaping groove 7 to compact the rice. When the limit component 15 reaches the limit groove 4, the limit strip 153 automatically engages, so that the installation platform 10 and the upper mold 11 change from the moving state to the locked state.

[0067] S4: With the installation platform 10 locked in position, press down the first extrusion plate 165 to make the discharge pipe 161 go down and insert into the center of the compacted rice ball. Then press down the second extrusion plate 168 to drive the compression rod 166 down and squeeze the fluid filling that has flowed into the discharge pipe 161 in S1 into the rice ball through the discharge hole 162.

[0068] This step is performed using the locked state of the mounting platform 10 in S3. The operator first presses the first extrusion plate 165 to insert the discharge pipe 161 into the rice ball, and then presses the second extrusion plate 168. The compression rod 166 pushes the sealing ring 167 to squeeze the filling out of the discharge hole 162 into the rice ball.

[0069] S5: Keeping the pressing and locking state of the rice ball by the mounting platform 10 and the upper mold 11 in S3 unchanged, operate the fixing component 9 to release the locking connection between the lower mold 5 and the fixed base 1; hold the lifting handle 8 of the lower mold 5 and lift the lower mold 5 vertically upward; during the lifting process of the lower mold 5, since the upper mold 11 is locked and kept stationary by the limiting component 15, the scraping plate 13 at the bottom of the upper mold 11 performs relative scraping motion on the inner wall of the shaping groove 7, so that the rice ball is separated from the side wall of the lower mold 5; after the lower mold 5 is completely separated from the rice ball, the shaped and filled rice ball is retained on the surface of the fixed base 1;

[0070] This step is reverse demolding. The limiting component 15 keeps the mounting platform 10, the upper mold 11 and the scraping plate 13 stationary. The operator releases the fixing component 9 and uses the lifting handle 8 to lift the lower mold 5 upward. The lower mold 5 moves upward, and the rice ball is pressed down by the upper mold 11 and remains on the fixed base 1.

[0071] S6: Then operate the lever 151 of the limit component 15 to release the lock of the mounting platform 10, lift the mounting platform 10 upward to reset the upper mold 11, and finally take the finished multi-flavor rice ball from the fixed base 1.

[0072] This step is to reset the device. The operator pulls the limit bar 153 by using the lever 151 to disengage it from the limit slot 4. The locking of the limit component 15 is released, and the mounting platform 10 and the upper mold 11 can be lifted upwards. The finished rice ball remains on the fixed base 1 to wait for the operator to take it away.

[0073] Working principle: When making multi-flavor rice balls, the operator places the lower mold 5 on the fixed base 1 and drives the connecting buckle 92 to fasten the hook seat 91 by rotating the operating handle 93, so that the lower mold 5 and the fixed base 1 form a rigid connection to prevent displacement during subsequent operations. An appropriate amount of rice is filled into the shaping groove 7 of the lower mold 5, and then the liquid filling is pre-injected into each upper mold 11. The liquid filling fills the discharge pipe 161 with its own fluidity. Then, the operator holds the lifting handle 8 and presses down, causing the upper mold 11 to descend vertically along the limiting lifting rod 3 into the shaping groove 7. As the pressing depth increases, the rice is compressed and shaped. At this time, the first compression spring 152 inside the mounting platform 10 pushes the limiting clip 153 to pop out and engage in the limiting clip groove 4 on the side of the limiting lifting rod 3, automatically locking the mounting platform 10 at the current compaction height, maintaining continuous pressure on the rice, and completing the initial shaping.

[0074] Then, with the installation platform 10 locked and stationary, the first extrusion plate 165 is pressed down. Under pressure, the discharge pipe 161 overcomes the resistance of the second compression spring 164 and moves downward, passing through the mold cover 12 and inserting into the center of the already compacted rice ball, forming an injection channel. Immediately afterwards, the second extrusion plate 168 is pressed down, driving the internal compression rod 166 to slide down inside the discharge pipe 161. The sealing ring 167 at the bottom of the compression rod 166 pushes the pre-stored filling inside, which is forced into the rice ball through the discharge hole 162 at the bottom, completing the filling. After the hand pressure is removed, the compressed second compression spring 164 releases energy, pushing the discharge pipe 161 and the first extrusion plate 165 to return to their original position. The discharge pipe 161 exits the rice ball, while the filling remains in the center of the rice ball.

[0075] Finally, the locking component 9 releases the locking relationship between the lower mold 5 and the fixed base 1. At this time, the installation platform 10 is still locked to the limit lifting rod 3 by the limit component 15. The upper mold 11 continues to press down on the top of the rice ball, so that the rice ball is restricted to the surface of the fixed base 1 and cannot move upward. The operator holds the lifting handle 8 and lifts the lower mold 5 vertically upward. The side wall of the shaping groove 7 of the lower mold 5 slides upward and separates from the side of the rice ball. During the upward movement of the lower mold 5, the scraping plate 13 fixed at the bottom of the upper mold 11 scrapes against the inner wall of the shaping groove 7, scraping off the rice residue adhering to the groove wall. After the lower mold 5 is completely lifted and separated from the rice ball, the complete rice ball remains on the fixed base 1. At this time, the toggle lever 151 is moved to retract the limit clip 153, unlocking and lifting the installation platform 10 to a certain height and locking the position. The multi-flavor rice ball can then be directly removed after it is made.
