Description

Technical Field

[0001] This application relates to the field of food production equipment, specifically to a glutinous rice ball forming machine. Background Technology

[0002] Tangyuan molding refers to the technique of physically pressing tangyuan (glutinous rice balls) to create raised textures, patterns, or text on their surface. Exquisite patterns can significantly enhance the visual impact and appeal of products, strengthen brand recognition, and increase product added value.

[0003] Existing glutinous rice ball molding processes can be categorized into manual and automatic molding based on their level of automation. Manual molding is the simplest method, where an operator places the dough into a mold and presses it. However, it is inefficient, requires a large amount of manpower, and product quality is affected by human error, resulting in poor consistency. Automated equipment typically includes a worktable for placing the glutinous rice balls and a pneumatic or electric pressing head. The pressing head can be fitted with molds for different patterns, and by triggering the pressing head to press down, the pattern is printed on the surface of the glutinous rice balls, significantly improving production efficiency.

[0004] However, in the process of implementing the technical solution in the embodiments of this application, the inventors of this application discovered that traditional glutinous rice ball pressing equipment can only press the pattern on one side of the glutinous rice ball, and cannot form both sides at the same time, which makes it difficult to meet the production needs of double-sided printing and pressing of glutinous rice balls in actual production.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0008] In some embodiments of this disclosure, the powder-spreading mechanism includes supports disposed on both sides of the conveying mechanism, a powder-spreading box disposed above the conveying mechanism via the supports and having a screen at its bottom, and a vibrator for vibrating the powder-spreading box.

[0009] In some embodiments of this disclosure, the forming assembly includes guide rods vertically fixed to the frame on both sides of the conveying mechanism, a top plate horizontally fixed to the top of the guide rods, a movable plate passing through the guide rods, and a movable cylinder fixed to the top plate for driving the movable plate to move along the guide rods; the forming mold is disposed at the bottom of the movable plate.

[0010] In some embodiments of this disclosure, the forming mold includes a mold plate located directly above the slot plate via a connecting rod connected to the bottom of the movable plate and having mold holes corresponding one-to-one with the glutinous rice ball placement slots of the glutinous rice ball tray; each mold corresponding one-to-one with each mold hole and having its top end fixed to the action plate; a spring located between the mold plate and the action plate and passing through each mold; and a compression cylinder fixed to the bottom of the movable plate for pressing the action plate.

[0015] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: using the glutinous rice ball tray as a mold for glutinous rice ball molding can effectively reduce the steps required for double-sided molding while achieving the effect of double-sided molding of glutinous rice balls. This allows the glutinous rice balls to be formed directly in the glutinous rice ball tray, avoiding the need for repackaging and other processes.

[0021] The programs involved or relied upon in the following embodiments are all conventional or simple programs in this technical field. Those skilled in the art can make conventional choices or adaptive adjustments according to specific application scenarios.

[0022] To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] To address the technical problem that existing glutinous rice ball forming equipment cannot meet the requirements for double-sided forming and printing, this example discloses a glutinous rice ball forming machine. (See attached image) Figure 1 It includes a frame 1, a conveying mechanism 2, a powder spreading mechanism 3, and a molding mechanism 4.

[0024] The frame 1 is used to install and fix the conveying mechanism 2, the powder spreading mechanism 3 and the molding mechanism 4. In this embodiment, in order to facilitate the movement of the equipment as needed, the bottom of the frame 1 is equipped with several wheels with locking mechanisms.

[0025] See Figure 1 In this embodiment, after the glutinous rice balls are placed in the glutinous rice ball tray, they are conveyed to the glutinous rice ball molding machine by the upstream conveyor belt 10 for embossing. After the glutinous rice ball tray containing the pastries is conveyed to the glutinous rice ball molding machine by the operation of the upstream conveyor belt 10, it is necessary to sprinkle powder before the embossing operation to prevent the glutinous rice balls from sticking to the mold. Therefore, the powdering and embossing operations need to be carried out at different workstations. In order to realize the movement of the glutinous rice ball tray entering the glutinous rice ball molding machine, the glutinous rice ball molding machine is equipped with a conveying mechanism 2. The conveying mechanism 2 is fixedly installed on the upper surface of the frame 1. The glutinous rice ball tray is moved forward by the conveying mechanism 2 to carry out the powdering and molding processes in sequence.

[0026] For details, see Figure 2 In this example, the conveying mechanism 2 includes an infeed plate 21 fixed to the frame 1 via a frame and located downstream of the end of the upstream conveyor belt 10. Driven by the upstream conveyor belt 10, the glutinous rice ball tray 11 is pushed and placed on the upper surface of the infeed plate 21. The infeed plate 21 has a certain length, and to allow the glutinous rice ball tray 11 to move further along the infeed plate 21, powdering and pressing processes are performed. See also... Figure 2 Conveyor belts 22 are symmetrically arranged on both sides of the infeed plate 21, and the two conveyor belts 22 are respectively fixed to the upper surface of the frame 1 by brackets. However, since the two conveyor belts 22 are respectively located on both sides of the infeed plate 21, they cannot effectively contact the glutinous rice ball tray 11, making it difficult to push the glutinous rice ball tray along the infeed plate 21. Therefore, in this embodiment, several connecting plates are arranged at equal intervals and perpendicularly on the outer surface of the conveyor belts 22, and the connecting plates between the two conveyor belts are symmetrically positioned, and further refer to Figure 2Push plates 23 are installed at the connecting plate to interfere with the position of the glutinous rice ball tray at the inlet plate. A transition section is set between the conveyor belt 22 and the upstream conveyor belt 10. Thus, after the glutinous rice ball tray reaches the tail of the upstream conveyor belt 10, the push plate on the upper surface of the conveyor belt can effectively contact the tail end of the glutinous rice ball tray 11 as the conveyor belt 22 rotates and flips. Then, it takes over from the upstream conveyor belt to continue pushing the glutinous rice ball tray 11 forward along the inlet plate 21.

[0027] Before the molding process, powdering is performed. For details, please refer to [link / reference]. Figure 1 The powder-sprinkling mechanism 3 is located upstream of the conveying mechanism 2. It includes a powder-sprinkling box 31 positioned directly above the inlet plate 21 of the conveying mechanism 2. The powder-sprinkling box 31 is fixed to the frame 1 by supports located on both sides of the conveying mechanism. In this embodiment, the bottom of the powder-sprinkling box 31 has powder-sprinkling holes corresponding to the positions of the glutinous rice ball placement slots in the glutinous rice ball tray, and each powder-sprinkling hole is covered with a sieve that allows powder to pass through. However, because the powder is small, it is difficult for it to leak out of the sieve under its own weight. Therefore, in this example, the powder-sprinkling mechanism includes a vibrator 32. When the glutinous rice ball tray moves directly below the powder-sprinkling box, the vibrator 32 is activated, and the powder inside the powder-sprinkling box is sprinkled under vibration. To determine the running position of the glutinous rice ball tray and facilitate timely activation of the vibrator 32 for powder-sprinkling operations, see [link to relevant documentation]. Figure 2 In this example, the powder-sprinkling mechanism 3 also includes a photoelectric sensor 33 for detecting the running position of the glutinous rice ball tray. In this example, the photoelectric sensor is mounted on the top of the inlet plate via a frame plate, so that after detecting the glutinous rice ball tray, it feeds back the position signal of the glutinous rice ball tray to the controller, which then makes it easier for the controller to control the conveyor belt to stop and start the vibrator to perform the powder-sprinkling operation when the glutinous rice ball tray runs directly under the powder-sprinkling box.

[0028] After being sprinkled with powder, the glutinous rice balls in the tray are conveyed to the molding mechanism 4 for molding. See details below. Figures 1-3 In this embodiment, the forming mechanism 4 includes a tray pushing assembly and a forming component disposed above the tray pushing assembly. The forming component includes guide rods 41 vertically fixed to corresponding positions on the top surface of the frame 1 on both sides of the conveying mechanism. In this example, four parallel guide rods 41 are provided. A movable plate 42 parallel to the top surface of the frame 1 slides through the guide rods. The bottom of the movable plate is connected to a forming mold, thereby achieving the forming process of the glutinous rice ball's upper surface by the movement of the movable plate 42 along the guide rods 41. For details on achieving the reciprocating movement of the movable plate 42 along the guide rods 41, see [link to documentation]. Figure 3 A top plate 43 parallel to the upper surface of the frame 1 is fixedly provided on the top of the guide rod 41. A moving cylinder 44 is fixedly provided at the center of the top plate 43. The actuating end of the moving cylinder is fixedly connected to the moving plate 42, thereby driving the moving plate 42 to move along the guide rod 41 through the moving cylinder 44.

[0029] See Figure 3 The forming mold located at the bottom of the movable plate 42 includes a mold plate 45, the four corners of which are fixedly connected to the bottom surface of the movable plate 42 by connecting rods. Additionally, the mold plate 45 has mold holes corresponding to the individual glutinous rice ball placement slots of the glutinous rice ball holder. Driven by the movable cylinder 44, the movable plate 42 moves vertically downwards, causing the mold plate 45 to press down close to or against the glutinous rice ball holder, stabilizing the holder and facilitating the forming process. Furthermore, the forming mold also includes molds 46 respectively embedded in the mold holes. In this example, to achieve simultaneous pressing of all molds 46, the tails of each mold are fixedly connected together by an actuating plate 47, thereby achieving unified movement of all molds 46. However, in this embodiment, considering that after each mold 46 is directly embedded in the mold hole, the mold will fall naturally under its own weight, a spring is sleeved on the outside of the rod of each mold. The spring is located between the action plate 47 and the mold plate 45. Thus, the mold is prevented from falling naturally under the action of the spring force. During the pressing operation, the spring itself deforms to avoid interfering with the pressing of the mold. At the same time, after pressing, the spring force can provide power for the mold to reset.

[0030] Additionally, in order to provide pressure on the action plate 47 during the molding process to achieve the downward pressing of the mold, see [reference needed]. Figure 3 In this example, a compression cylinder 48 is fixedly installed at the bottom of the movable plate 42. Thus, when there is a need for compression action, the actuating end of the compression cylinder 48 extends and contacts the top surface of the actuating plate 47, thereby compressing the actuating plate 47 and driving each mold to press down, so as to realize the compression printing on the surface of the glutinous rice ball. In this embodiment, considering that the glutinous rice ball tray has a certain depth, and the mold plate 45 can only contact the top edge of the tray, in order to ensure the accuracy and reliability of the molding and thus improve the molding quality, a pressing plate 49 is fixedly installed on the bottom plate of the mold plate 45. The bottom contour of the pressing plate 49 matches the top contour of the glutinous rice ball tray, so that after pressing down, the pressing plate 49 can fully contact the top surface of the glutinous rice ball tray, thereby limiting the position of the glutinous rice ball tray and each glutinous rice ball. At the same time, in this example, the bottom surface of the pressing plate 49 is provided with an annular flange of a certain length at the position of each glutinous rice ball placement slot in the glutinous rice ball tray, so as to seal the gap between the glutinous rice ball and the glutinous rice ball placement slot when pressing down, thereby achieving the effect of limiting the position of the glutinous rice ball and thus avoiding the problem of inconsistent surface molding and printing positions of each glutinous rice ball due to misalignment.

[0031] To achieve the pressing of the bottom surface of the glutinous rice balls, in this embodiment, the required pressing pattern is set at the bottom of each glutinous rice ball placement slot in the glutinous rice ball tray 11. Thus, when the pressing component presses the upper surface of the glutinous rice balls, the bottom surface of the glutinous rice balls, relying on the pattern in the placement slot, can also achieve the effect of pressing and printing under the pressing pressure. Considering that the glutinous rice ball tray may slightly deviate from the running axis during its movement along the infeed plate under the push of the corresponding push plate of the conveying mechanism; and that the pressing mechanism exerts a certain pressure when pressing down, thus requiring comprehensive and effective support for the glutinous rice ball tray, therefore, in this embodiment, see... Figure 2 The forming mechanism includes a tray pushing assembly 5. Specifically, the tray pushing assembly 5 includes a groove plate 51 located at the tail of the inlet plate 21 and below the plane of the inlet plate 21. The groove plate 51 is fixed to the top surface of the frame 1 by a corresponding bracket and is collinear with the forming assembly in the vertical direction. The upper surface of the groove plate 51 has a groove that matches the bottom contour of the glutinous rice ball tray 11. Driven by the conveying mechanism, the glutinous rice ball tray can fall from the inlet plate into the matching groove of the groove plate 51, so that the groove plate provides the necessary support force to the glutinous rice ball tray during forming, ensuring the double-sided forming effect of the glutinous rice ball.

[0032] In some other embodiments, considering that air exists between the glutinous rice dough and the glutinous rice placement slots of the glutinous rice tray during the pressing process, in order to facilitate the venting during pressing, venting holes are respectively opened at the bottom of each glutinous rice placement slot of the glutinous rice tray to release air in a timely manner and avoid adverse effects on the pressing and printing quality.

[0033] See Figure 2 In this example, the conveying mechanism also includes an exit plate 24 located downstream of the inlet plate 21 and coaxially arranged with it. Thus, the glutinous rice ball trays, after being pressed by the pressing mechanism, are pushed into the exit plate 24 by the conveying mechanism and output along the exit plate 24 to the next process. During the pressing operation, the glutinous rice ball trays fall into the grooves of the slot plate 51. To ensure that the glutinous rice ball trays can move smoothly to the exit plate 24 after pressing, several symmetrical slots are provided in the slot plate 51, each slot containing a top plate. Each top plate is arranged along the conveying direction of the conveying mechanism. In addition, a push cylinder 52 is provided below the groove plate 51. The push cylinder 52 is fixed to the upper surface of the frame 1, and the movable end of the push cylinder 52 is fixedly connected to the top plate. Thus, the push cylinder 52 drives the top plate, which is fitted in the slot, to achieve vertical movement. After the glutinous rice balls are pressed in the glutinous rice ball tray, the push cylinder 52 drives the top plate to push the glutinous rice ball tray out of the groove of the groove plate 51, so that the bottom surface of the glutinous rice ball tray is flush with the top surface of the box exit plate 24, and then enters the box exit plate 24 under the drive of the conveying mechanism.
