Description

Technical Field

[0001] The present invention relates to the technical field of rice cake forming and printing, and specifically provides a rice cake forming and printing device. Background Art

[0002] As a traditional pastry, rice cakes are deeply loved for their soft texture and diverse shapes. In the industrial production of rice cakes, forming and printing are key processes, and the equipment is required to simultaneously achieve functions such as raw material filling, pressing and forming, printing, and subsequent screening. Traditional rice cake production equipment usually adopts a segmented operation, and manual material transfer is relied on between each process. This not only results in low production efficiency, but also easily causes pollution or deformation of the rice cakes due to manual contact. With the increasing demand for food processing automation, developing a rice cake forming and printing device integrating multiple functions has become an industry trend.

[0003] Currently, in the rice cake forming equipment on the market, the processes of raw material filling and rice cake transfer rely on manual operations. For example, it is necessary to manually carry the mold filled with raw materials to the pressing die station, and then manually move the rice cake to the screening area after forming. This process is not only time-consuming and laborious, but also the manual handling is likely to cause damage to the shape of the rice cake or the powder on the surface to fall off, affecting product consistency; in addition, the screening link of traditional equipment mostly uses a fixed sieve plate, lacks power drive, and only relies on the self-gravity of the rice cake to slide down, resulting in ineffective removal of residual powder, and additional manual cleaning is required, increasing production costs and the difficulty of sanitation management. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a rice cake forming and printing device, which solves the problems that the processes of raw material filling and rice cake transfer rely on manual operations, and in addition, the screening link of traditional equipment mostly uses a fixed sieve plate.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A rice cake forming and printing device, including a first support frame. The left end of the first support frame is installed with a motor through a fixing frame. The driving end of the motor is fixedly connected with a bidirectional lead screw. The outer wall of the bidirectional lead screw is connected with a material storage box through a threaded sleeve. The inner wall of the material storage box is rotatably connected with a pressing roller. The right end of the bidirectional lead screw is fixedly connected with a first rotating rod. The outer wall of the first rotating rod is rotatably connected to the inner wall of the first support frame. The outer wall of the first rotating rod is connected with an eccentric wheel through a steering component. The middle part of the inner wall of the first support frame is fixedly connected with a forming mold. The inner wall of the forming mold is slidably connected with a lifting plate. The top end of the lifting plate is fixedly connected with a lifting block. The bottom end of the lifting plate is fixedly connected with a lifting rod. The outer wall of the lifting rod is slidably connected to the inner wall of the forming mold. The right side of the inner wall of the first support frame is connected with a sieve plate through a sliding rod. Both the front and rear ends of the sieve plate are fixedly connected with a first support plate. The front end of the front first support plate is arranged on the outer wall of the eccentric wheel. The middle part of the top end of the first support frame is fixedly connected with a second support frame. The inner wall of the top side of the second support frame is connected with a printing press mold through a driving component. Both the front and rear sides of the top end of the printing press mold are connected with a moving plate through a linkage component. The top end of the moving plate is arranged at the bottom end of the lifting rod.

[0006] Preferably, the steering component includes a first bevel gear located on the outer wall of the first rotating rod. The right end of the first bevel gear is meshed and connected with a second bevel gear. The inner wall of the second bevel gear is fixedly connected with a second rotating rod. The outer wall of the second rotating rod is rotatably connected to the inner wall of the eccentric wheel. The outer wall of the second rotating rod is rotatably connected to the inner wall of the first support frame.

[0007] Preferably, the driving component includes a hydraulic rod located on the inner wall of the top side of the second support frame. The bottom end of the hydraulic rod is fixedly connected with a pressing plate. The bottom end of the pressing plate is fixedly connected to the top end of the printing press mold.

[0008] Preferably, the top end of the pressing plate is fixedly connected with a guiding rod. The outer wall of the guiding rod is slidably connected to the inner wall of the second support frame. The top end of the guiding rod is fixedly connected with a connecting plate.

[0009] Preferably, the linkage component includes a second support plate located at the top end of the second support frame. The inner circumference of the second support plate is in sliding contact with an L-shaped rod. One end of the L-shaped rod is connected to the connecting plate, and the other end of the L-shaped rod is connected to the moving plate.

[0010] Preferably, the top end of the moving plate is fixedly connected with a limiting rod. The outer wall of the limiting rod is slidably connected to the inner wall of the first support frame. Both the front and rear ends of the first support frame are fixedly connected with limiting sleeves. The inner wall of the limiting sleeve is sleeved on the outer wall of the L-shaped rod.

[0011] Preferably, springs are arranged at both the separated ends of the two first support plates. One ends of the multiple springs are connected to the first support frame, and the other ends of the multiple springs are connected to the first support plate.

[0012] Preferably, two symmetrical stoppers are arranged on the inner circumference of the first support frame. A material guiding groove is fixedly connected to the right end of the first support frame, and a slag storage box is arranged on the inner wall of the bottom side of the first support frame.

[0013] Preferably, it includes the following steps:

[0014] Step 1: Put the raw materials for making rice cakes into the storage box.

[0015] Step 2: Start the motor to drive the storage box to move so that the raw materials inside fill the forming groove of the forming mold. Then, turn off the motor when the storage box returns to its original position.

[0016] Step 3: Start the hydraulic rod to drive the printing die to press downwards, so that the raw materials in the forming mold are formed and have a pattern.

[0017] Step 4: Drive the connecting plate to move upwards through the hydraulic rod, and drive the jacking rod to eject the rice cake in the forming mold from the forming groove through the L-shaped rod and the moving plate.

[0018] Step 5: Start the motor again to push the rice cake to the sieve plate through the storage box.

[0019] Step 6: Through the vibration of the sieve plate, shake the excess powder remaining on the rice cake into the slag storage box.

[0020] Step 7: Finally, discharge the material through the material guiding groove.

[0021] Preferably, in Step 6, the motor drives the bidirectional lead screw and the first rotating rod to rotate simultaneously, thereby driving the first bevel gear to rotate. Under the meshing action with the second bevel gear, the eccentric wheel is driven to rotate through the second rotating rod, so that the sieve plate can vibrate.

[0022] Working principle: Put the raw materials for making rice cakes into the storage box. Then start the motor to drive the bidirectional lead screw to rotate, which can drive the storage box to reciprocate to the forming mold through the threaded sleeve, so that the raw materials in the storage box fill the forming groove of the forming mold. When filling, the pressure roller in the storage box can compact the raw materials in the forming groove. After the forming groove is filled with raw materials, turn off the motor when the storage box returns to its original position. Then start the hydraulic rod to drive the printing die to press and form the rice cake and form a pattern. After the hydraulic rod lifts the printing die upward, it will drive the L-shaped rod to rise through the guide rod and the connecting plate, thereby driving the moving plate to move upward, so that the moving plate jacks up the jacking rod. The jacking rod will move in the forming mold, and then drive the jacking plate and the jacking block to eject the rice cake in the forming groove. Then start the motor again to drive the storage box to push the rice cake onto the sieve plate. Then lower the printing die by a certain distance through the hydraulic rod, so that the moving plate no longer jacks up the jacking rod. Then when the storage box is driven by the bidirectional lead screw to reciprocate, the raw materials fill the forming groove again to prepare for the next forming and printing. At this time, the rotating rod 1 will rotate together with the bidirectional lead screw, thereby driving the bevel gear 1 to rotate. Under the meshing action of the bevel gear 1 and the bevel gear 2, the eccentric wheel can be driven to rotate through the rotating rod 2. Since the center of the eccentric wheel is not on the same straight line as the rotating rod 2, when the eccentric wheel rotates, it will drive the sieve plate to vibrate through the support plate 1, and then shake the excess powder on the outer surface of the rice cake on the sieve plate into the slag storage box. Since the sieve plate is inclined and arranged inside the support frame 1, when vibrating, the rice cake will slide onto the guide groove little by little for discharging.

[0023] The present invention provides a rice cake forming and printing device. It has the following beneficial effects:

[0024] 1. In the present invention, the storage box is driven by the bidirectional lead screw, which can not only achieve the accurate filling of raw materials into the forming mold, but also push the formed rice cake to the sieve plate for screening after the rice cake is formed. This design simplifies the equipment structure, reduces the manual transfer link of the rice cake in the traditional process, improves the production efficiency, and at the same time avoids the problems of rice cake deformation or pollution caused by manual operation.

[0025] 2. In the present invention, through the linkage design of the hydraulic rod, the L-shaped rod, the moving plate and the jacking rod, the automatic connection between the downward pressing and forming of the printing die and the ejection of the rice cake is realized. When the hydraulic rod drives the printing die to rise, the jacking action is triggered synchronously, without an additional power source, saving energy consumption while ensuring the coordination and stability of the action, effectively improving the reliability of rice cake demoulding and the production continuity.

[0026] 3. The present invention utilizes a motor to drive a bidirectional screw rod, and transmits power to the eccentric wheel through rotating rod 1, bevel gear 1, bevel gear 2 and rotating rod 2, so that the screen plate produces a shaking screening action. This design cleverly reuses the motor power and does not require a separate screening drive device, thereby reducing equipment costs and energy consumption. The cooperation between the eccentric wheel and the spring stabilizes the shaking frequency of the screen plate, which can effectively remove excess powder on the surface of the rice cake, avoid damage to the shape of the rice cake caused by excessive shaking, and improve product quality.

[0034] Example:

[0035] Please refer to the attached Figure 1 -Attached Figure 5, an embodiment of the present invention provides a rice cake forming and printing device, including a first support frame 1. A motor 5 is installed at the left end of the first support frame 1 through a fixing frame. The driving end of the motor 5 is fixedly connected to a bidirectional lead screw 6. The outer wall of the bidirectional lead screw 6 is connected to a storage box 2 through a threaded sleeve. A pressing roller 3 is rotatably connected to the inner wall of the storage box 2. The right end of the bidirectional lead screw 6 is fixedly connected to a first rotating rod 7. The outer wall of the first rotating rod 7 is rotatably connected to the inner wall of the first support frame 1.

[0036] Specifically, put the rice cake raw materials into the storage box 2, start the motor 5 to drive the bidirectional lead screw 6 to rotate, and drive the storage box 2 to reciprocate along the first support frame 1 to the upper part of the forming mold 30 through the threaded sleeve. The pressing roller 3 in the storage box 2 rotates synchronously with its movement, compresses the raw materials falling into the forming groove of the forming mold 30, and ensures that the filling is uniform and compact. When the forming groove is filled, the storage box 2 returns to its original position, and the motor 5 pauses. The bottom of the printing press mold 19 is provided with pattern protrusions, which press patterns on the surface of the rice cake when pressing down, and at the same time apply pressure to the raw materials to make them form. It is the core component for realizing rice cake printing and shaping. There are multiple forming grooves in the forming mold 30, which are used to define the shape and size of the rice cake. Its inner wall is slidably matched with the jacking plate 25 to ensure the smooth progress of the filling, forming and ejecting processes.

A second rotating rod <10> is fixedly connected to the inner wall of the second bevel gear <9>. The outer wall of the second rotating rod <10> is rotatably connected to the inner wall of the eccentric wheel <11>. The outer wall of the second rotating rod <10> is rotatably connected to the inner wall of the first support frame <1>. Among them, a hydraulic rod <17> is located on the inner wall of the top side of the second support frame <16>. The bottom end of the hydraulic rod <17> is fixedly connected with a pressing plate <18>. The bottom end of the pressing plate <18> is fixedly connected to the top end of the printing die <19>. The top end of the pressing plate <18> is fixedly connected with a guide rod <20>. The outer wall of the guide rod <20> is slidably connected to the inner wall of the second support frame <16>. The top end of the guide rod <20> is fixedly connected with a connecting plate <21>. Among them, a second support plate <29> is located at the top end of the second support frame <16>.

One end of each of the multiple springs <14> is connected to the first support frame <1>. The other end of each of the multiple springs <14> is connected to the first support plate <12>.

[0038] Specifically, start the hydraulic rod 17. The pressing plate 18 is pushed to drive the printing die 19 to move downward, applying pressure to the raw materials in the forming die 30 to complete the shaping of the rice cakes and press the preset patterns on their surfaces. After the pressing is completed, the hydraulic rod 17 drives the printing die 19 to move upward and reset. When the hydraulic rod 17 rises, the connecting plate 21 is driven to move upward synchronously through the guide rod 20. The connecting plate 21 pulls the moving plate 23 upward through the L-shaped rod 22. The moving plate 23 pushes the jacking rod 24, driving the jacking plate 25 and the jacking block 26 to eject the rice cakes in the forming die 30 from the forming groove. Subsequently, start the motor 5 again. The storage box 2 pushes the ejected rice cakes onto the right sieve plate 13. When the motor 5 continues to operate, the bidirectional lead screw 6 drives the first rotating rod 7 to rotate synchronously. Through the meshing transmission of the first bevel gear 8 and the second bevel gear 9, the second rotating rod 10 is driven to drive the eccentric wheel 11 to rotate. The eccentric design of the eccentric wheel 11 causes it to push the front support plate 12 during rotation. With the elastic action of the rear spring 14, the sieve plate 13 generates a reciprocating vibration. The sieve plate 13 is inclined. During the vibration process, the powder residues on the surface of the rice cakes fall into the slag storage box 4 through the sieve holes, and the rice cakes slide along the sieve plate 13 to the material guiding groove 15 for discharging. At the same time, the storage box 2 fills the forming die 30 with materials again, entering the next production cycle. The spring 14 is installed outside the support plate 12, providing a reset elastic force for the sieve plate 13. With the pushing action of the eccentric wheel 11, the sieve plate 13 generates a stable reciprocating vibration. The material guiding groove 15 guides the rice cakes on the sieve plate 13 to discharge smoothly, completing the collection of finished products. Its inclined angle design ensures that the rice cakes can slide automatically by gravity. The limiting rod 27 is fixed to the top of the moving plate 23 and slidably cooperates with the first support frame 1 to limit the movement track of the moving plate 23 to prevent it from shifting in the horizontal direction and ensure the stability of the jacking action. The limiting sleeve 28 is sleeved outside the L-shaped rod 22 and fixedly connected to the first support frame 1 to guide and limit the movement of the L-shaped rod 22 and ensure the transmission accuracy of the linkage mechanism. The stop block 31 is a triangular prism, which can guide the rice cakes onto the sieve plate 13. The slag storage box 4 can collect the excess powder that falls during the screening process of the sieve plate 13, facilitating centralized cleaning, keeping the interior of the equipment clean, reducing raw material waste. The guide rod 20 slidably cooperates with the second support frame 16 to provide guidance for the up and down movement of the pressing plate 18 and the printing die 19, ensuring the perpendicularity of the movement track during the pressing process and avoiding uneven shaping of the rice cakes caused by deviation. The connecting plate 21 connects the guide rod 20 and the L-shaped rod 22, transmitting the upward power of the hydraulic rod 17 to the L-shaped rod 22, triggering the jacking action and realizing the linkage control of pressing and demoulding.

[0039] It includes the following steps:

[0040] Step 1: Put the raw materials for making rice cakes into the storage box 2;

[0041] Step 2: Start the motor 5 to drive the storage box 2 to move so that the raw materials inside fill the forming groove of the forming die 30. Then, turn off the motor 5 when the storage box 2 returns to its original position;

[0042] Step 3: Start the hydraulic rod 17 to drive the printing die 19 to press downwards, so that the raw materials in the forming die 30 are formed and have patterns printed on them.

[0043] Step 4: Drive the connecting plate 21 to move upwards through the hydraulic rod 17, and drive the jacking rod 24 to eject the rice cake in the forming die 30 from the forming groove through the L-shaped rod 22 and the moving plate 23.

[0044] Step 5: Start the motor 5 again to push the rice cake to the sieve plate 13 through the storage box 2.

[0045] Step 6: Shake off the excess powder remaining on the rice cake into the slag storage box 4 through the shaking of the sieve plate 13.

[0046] Step 7: Finally, discharge the material through the material guide groove 15.

[0047] The motor 5 drives the bidirectional lead screw 6 and the first rotating rod 7 to rotate simultaneously, thereby driving the first bevel gear 8 to rotate, and driving the eccentric wheel 11 to rotate through the second rotating rod 10 under the meshing action with the second bevel gear 9, so that the sieve plate 13 can shake.

[0048] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
