Description

Technical Field

[0001] This utility model relates to the field of rice mooncake forming technology, specifically a rice mooncake pressing and forming device. Background Technology

[0002] With the upgrading of traditional pastry consumption and the popularization of healthy eating concepts, rice mooncakes, with their low oil and sugar content and soft and glutinous texture, have seen continuous growth in market demand. The core production process of rice mooncakes is pressing and molding. The raw materials are made from glutinous rice flour, indica rice flour, etc. as a base, with the addition of fruit and vegetable juices, grains and other auxiliary materials. They are characterized by high viscosity, soft texture and easy deformation, which puts special requirements on the adaptability of molding equipment. At present, rice mooncake pressing and molding equipment mainly consists of mold modules and pressure application mechanisms. The mold usually has a built-in pattern structure. The rice material is pressed and shaped by manual or semi-automatic pressure application. Because the rice material is highly viscous and easily sticks to the cavity after molding, existing equipment generally uses a rigid rod as the core demolding component. The molded mooncake is pushed out of the cavity by manual pushing of the ejector rod, thus completing the demolding operation.

[0003] The core characteristics of rice mooncakes are their soft texture and strong stickiness, which are significantly different from traditional pastry ingredients. Existing rigid ejector demolding methods use point contact or line contact pushing structures, which are prone to local stress concentration during the pushing process. The force of the ejector is concentrated at the contact point, which can directly cause the mooncake edges to crack, the surface to have indentations, or the pattern to collapse after molding, seriously affecting the integrity of the product's appearance. Especially when adapting to molds with complex patterns, instantaneous shear force can easily form between the rigid ejector and the gap of the mold pattern. Under the action of shear force, the sticky rice material is difficult to maintain the pattern shape, often resulting in incomplete pattern details and incomplete replication, which greatly reduces the product qualification rate and fails to meet the standardized requirements of appearance quality for large-scale production. Utility Model Content

[0004] The purpose of this invention is to provide a rice mooncake pressing and molding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rice mooncake pressing and molding device, including an electric telescopic rod, the bottom end of which is fixedly connected to a mold;

[0006] The electric telescopic rod and the mold are jointly provided with a flexible demolding mechanism. The flexible demolding mechanism includes an inflatable airbag, a demolding airbag and two extrusion rods. A push plate is fixedly connected to the bottom end of the inflatable airbag. Symmetrically arranged connecting blocks are fixedly connected to the push plate. Springs are fixedly connected to the top of each connecting block. A passage groove is opened on the push plate. A telescopic tube is fixedly connected to the inflatable airbag at the position corresponding to the passage groove.

[0007] Preferably, the inflatable airbag is fixedly connected to the bottom end of the electric telescopic rod, and the demolding airbag is fixedly connected to the top inside the mold.

[0008] Preferably, the extrusion rods are symmetrically and fixedly connected to the top of the mold.

[0009] Preferably, the inflatable airbag and the telescopic tube are in a connected state, the bottom end of the telescopic tube penetrates through the top wall of the mold and is fixedly connected to and through the demolding airbag, and the telescopic tube is fixedly connected to the mold.

[0010] Preferably, the top end of the telescopic tube is located inside the passageway.

[0011] Preferably, the top end of each spring is fixedly connected to the bottom end of the electric telescopic rod.

[0012] Preferably, both the inflatable airbag and the push plate are cylindrical, and the surface of the demolding airbag is patterned.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the flexible demolding mechanism can be linked with the electric telescopic rod. When the electric telescopic rod retracts, the internal components of the drive mechanism work together to quantitatively deliver gas to the demolding airbag, causing the demolding airbag to inflate evenly. During the inflation process, the bottom wall of the demolding airbag expands downward in the vertical direction, forming a fully contacted surface with the mooncake surface, rather than the single-point contact of the traditional rigid structure. With the soft texture and uniform pressure transmission characteristics of the airbag, it can smoothly push the mooncake to separate from the mold, and avoid damage such as squeezing and scratching to the surface pattern of the mooncake, ensuring that the mooncake maintains its complete shape and clear pattern after demolding, and significantly improving the product appearance qualification rate.

[0019] Please see Figure 1-4 The present invention provides the following technical solution:

[0020] Example 1: Rice mooncake pressing and molding device, including electric telescopic rod 1, with mold 2 fixedly connected to the bottom end of electric telescopic rod 1;

[0021] In use, the electric telescopic rod 1 is installed on the mooncake production line and connected to an external controller. The controller controls the start of the electric telescopic rod 1. When the electric telescopic rod 1 starts, the output end extends downward. The downward extension of the output end of the electric telescopic rod 1 causes the mold 2 to move downward. The downward movement of the mold 2 presses and shapes the rice cakes on the conveyor line, thus completing the mooncake shaping process.

[0022] Example 2: The technical solution of this example that differs from Example 1 includes: the electric telescopic rod 1 and the mold 2 are jointly provided with a flexible demolding mechanism 3. The flexible demolding mechanism 3 includes an inflatable airbag 31, a demolding airbag 32 and two extrusion rods 33. The bottom end of the inflatable airbag 31 is fixedly connected to a push plate 34. Symmetrically arranged connecting blocks 35 are fixedly connected to the push plate 34. The top end of each connecting block 35 is fixedly connected to a spring 36. A passage groove 37 is opened on the push plate 34. A telescopic tube 38 is fixedly connected to the inflatable airbag 31 at the position corresponding to the passage groove 37.

[0023] The inflatable airbag 31 is fixedly connected to the bottom end of the electric telescopic rod 1, the demolding airbag 32 is fixedly connected to the top end of the mold 2, and the extrusion rod 33 is symmetrically fixedly connected to the top end of the mold 2. When the extrusion rod 33 rises, it is convenient to extrude the push plate 34. The inflatable airbag 31 is in a communication state with the telescopic tube 38. The bottom end of the telescopic tube 38 penetrates the top wall of the mold 2 and is fixedly connected to and through the demolding airbag 32. The telescopic tube 38 is fixedly connected to the mold 2. The inflatable airbag 31 is convenient to deliver gas to the demolding airbag 32 through the telescopic tube 38. The top end of the telescopic tube 38 is located inside the passage groove 37. The top end of the spring 36 is fixedly connected to the bottom end of the electric telescopic rod 1. The spring 36 is convenient to drive the inflatable airbag 31 to reset through the push plate 34. The inflatable airbag 31 and the push plate 34 are both cylindrical. The surface of the demolding airbag 32 is patterned.

[0024] In use, the extended output end of the electric telescopic rod 1 drives the mold 2 downward. The downward movement of the mold 2 stretches the telescopic tube 38, pressing the rice dough on the production line into a mooncake shape. Simultaneously, the pattern at the bottom of the demolding airbag 32 is imprinted on the top of the mooncake, thus completing the mooncake's shaping. At this point, the output end of the electric telescopic rod 1 retracts, driving the mold 2 upward. The upward movement of the mold 2 causes the telescopic tube 38 to gradually return to its original shape. At the same time, the mold 2 also drives the two extrusion rods 33 upward. When the extrusion rod 33 moves upward to the position where it aligns with the bottom end of the push plate 34, the continuously moving extrusion rod 33 will extrude pressure on the bottom end of the push plate 34. At this time, the push plate 34 will also move upward, which will cause the two connecting blocks 35 to move together. The upward movement of the connecting blocks 35 will compress and contract the corresponding springs 36. At the same time, the upward movement of the push plate 34 will also compress the inflatable airbag 31. The pressure on the inflatable airbag 31 will cause the internal gas to flow through the telescopic tube 38 into the demolding airbag 32. The demolding airbag 32 receives the inflated airbag 31. The gas in mold 1 will inflate, causing the bottom of the demolding airbag 32 to move downwards inside mold 2. At this point, the demolding airbag 32 will push the formed mooncake out of mold 2. The bottom of the demolding airbag 32 forms a fully contacted surface with the mooncake, rather than the single-point contact of a traditional rigid structure. Thanks to the soft texture and uniform pressure transmission characteristics of the demolding airbag 32, it can smoothly push the mooncake away from mold 2 while avoiding damage such as squeezing or scratching to the surface pattern of the mooncake, ensuring that the mooncake retains its intact shape and clear pattern after demolding. The texture significantly improves the product appearance qualification rate. When the output end of the electric telescopic rod 1 extends again, it will drive the mold 2 to move downward. The downward movement of the mold 2 will drive the extrusion rod 33 to move downward. After the extrusion rod 33 moves downward, it will no longer extrude on the bottom end of the push plate 34. At this time, the compressed spring 36 will exert force to reset. The reset spring 36 will drive the inflatable airbag 31 to reset to its original state. At this time, the gas in the demolding airbag 32 will return to the inflatable airbag 31 through the telescopic tube 38. Then, the pressing mold 2 will press and shape the new rice ball.
