Description

Technical Field

[0001] The invention relates to the technical field of mooncake processing, and in particular to a printing device used for mooncake processing. Background Art

[0002] As a traditional festival food, mooncakes require different molds for their processing due to the different materials of the mooncakes. Mooncake processing is diverse due to the different materials of the mooncakes. Traditional mooncakes mainly include Cantonese mooncakes, Su-style mooncakes and other different types of materials. Cantonese mooncakes have strict requirements on molds, usually using metal molds, which can provide support and facilitate demoulding. Su-style mooncakes often use wooden molds due to their crispy skin characteristics, which can maintain the layers and shape of the crispy skin.

[0003] However, since Cantonese-style mooncakes are usually processed and demoulded with metal molds, silicone molds may cause the mooncakes to shake in the molds due to low friction, affecting the accuracy of the printing position, while wooden molds may easily lead to insufficient printing force. For Su-style mooncakes, wooden molds can better maintain the integrity of the mooncake crust. If metal or silicone molds are used, the layers and shape of the crust may be destroyed during demoulding.

[0004] Therefore, depending on the different materials of mooncakes, companies usually need to purchase different processing molds, which increases procurement costs; at the same time, when switching to the production of different types of mooncakes, replacing the corresponding molds requires a lot of time and manpower, reducing production efficiency, and it is inconvenient to adapt different mooncakes to the same mold processing.

[0005] In view of this, the present invention provides a printing device for moon cake processing. Summary of the invention

[0009] The molding component is used for die-casting mooncakes, and the stamping component is used for printing the top of the mooncakes and assisting in demolding the mooncakes. When the stamping component descends, steam is output to disinfect the molding component. At the same time, edible oil leaks out from the inside of the molding component. When the stamping component rises, the edible oil is evenly spread on the inner wall of the molding component and the steam and edible oil outlets are blocked.

[0011] As a further improvement of the technical solution, an oil tank is fixedly connected to the inside of the bracket near the center position, a conduit is fixedly connected to the top of the oil tank, an oil pump is provided at the end of the conduit, a mold is fixedly connected to the bottom of the oil tank, flow parts are fixedly connected to the inside of multiple grooves in the bottom of the oil tank, and a stamping assembly is movably connected between the oil tank and the inside of the mold.

[0012] As a further improvement of the present technical solution, the circulation component includes a conical block, and a plurality of the conical blocks are respectively fixedly connected to a plurality of holes at the bottom of the oil tank; a orifice plate is movably connected to the top of the conical block, a push rod is fixedly connected to the bottom of the orifice plate, a piston is fixedly connected to the outer wall of the push rod near the center position, and the piston is movably connected to the inside of the conical block.

[0013] As a further improvement of the present technical solution, the stamping assembly includes a vacuum tube, which is fixedly connected to the inside of the oil tank, and the end of the vacuum tube passing through the oil tank is fixedly connected to an air pipe, and an evaporator is provided at the end of the air pipe, and the vacuum tube passing through the top of the oil tank is fixedly connected to a cylinder, and a piston rod is movably connected to the inside of the cylinder, and the end of the piston rod passing into the vacuum tube is fixedly connected to a baffle, and the end of the baffle is fixedly connected to a printing part, and the printing part is movably connected inside the mold.

[0014] As a further improvement of the present technical solution, the printed part includes a small flower plate, which is fixedly connected to the bottom of the baffle, a large flower plate is fixedly connected to the bottom of the small flower plate, a plurality of balls are movably connected between the large flower plate and the small flower plate near the edge of the large flower plate, and wreaths are movably connected inside the plurality of balls.

[0015] As a further improvement of the technical solution, the printing piece and the mold are both made of metal, and the diameter of the small flower plate is smaller than that of the large flower plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the printing device for mooncake processing, the mooncake is demoulded by pushing the stamping component downward, and in this process, the downward pressure can further deepen the printed pattern on the top of the mooncake, making the pattern on the surface of the mooncake clearer and more three-dimensional, ensuring the stable and consistent printing quality of each mooncake.

[0018] 2. In the printing device for moon cake processing, when the stamping component is demoulded, as the stamping component moves downward, steam will be released in a timely manner, and the steam will quickly fill the internal space of the molding component, and the molding component after demoulding will be fully and effectively disinfected, ensuring that the molding component is in a clean and hygienic state, providing reliable protection for the next moon cake processing operation;

[0019] Moreover, as the stamping component descends, edible oil will flow downward along the inner wall of the molding component, forming a thin oil film on the inner wall of the molding component. When the mooncakes are processed again, the friction between the mooncake material and the inner wall of the molding component will be significantly reduced, making it easier for the mooncakes to escape from the molding component and maintain their intact shape. It can also effectively prevent the mooncake surface from being damaged or scratched due to friction with the inner wall of the mold, thereby greatly improving the production quality and yield rate of mooncakes.

[0020] 3. In the printing device for processing moon cakes, when the stamping component starts to rise, the edible oil on the inner wall of the molding component is applied more evenly. On the one hand, after the moon cakes are subsequently printed and formed, the evenly distributed edible oil can greatly facilitate the demoulding operation of the moon cakes. On the other hand, it ensures that the various parts of the moon cakes are evenly stressed during demoulding, and there will be no partial detachment or partial residue caused by local adhesion, so that the moon cakes can be completely separated from the mold;

[0021] At the same time, when the stamping component rises to the top, the edible oil leakage hole of the molding component and the steam leakage hole of the stamping component are blocked to prevent unnecessary leakage of edible oil in a non-working state, avoid waste and pollution to the working environment, and block the steam leakage hole to ensure that the steam can be concentrated and effectively act on the inside of the molding component when it needs to be released, thereby improving the effect of steam sterilization and energy utilization efficiency.

[0034] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figure 1-Figure 4 As shown, the purpose of this embodiment is to provide a printing device for moon cake processing, including a base 1, a conveying device 11 is fixedly connected to the top of the base 1, the tops of the two sides of the base 1 passing through the conveying device 11 are fixedly connected to motors, a molding component 12 is fixedly connected between the top of the base 1 and the two motor output shafts, and a stamping component 13 is movably connected inside the molding component 12;

[0038] An oil pump is provided at the end of the molding assembly 12, and an evaporator is provided at the end of the stamping assembly 13. The stamping assembly 13 is located at the center of the molding assembly 12. Both the molding assembly 12 and the stamping assembly 13 are located directly above the conveying device 11.

[0039] The molding assembly 12 is used for die-casting the moon cakes, and the stamping assembly 13 is used for printing the top of the moon cakes and assisting in demoulding the moon cakes. When the stamping assembly 13 descends, steam is output to sterilize the molding assembly 12. At the same time, edible oil leaks out of the molding assembly 12. When the stamping assembly 13 ascends, the edible oil on the inner wall of the molding assembly 12 is evenly smeared, and the steam and edible oil outlets are blocked.

[0040] The improvement of this embodiment is that: the forming assembly 12 and the stamping assembly 13 move downward synchronously, so that the mooncake material on the conveying device 11 is led to the space between the forming assembly 12 and the stamping assembly 13, and as the two assemblies continue to press downward, the mooncake material gradually fills this specific area, thereby achieving precise extrusion molding of the mooncake;

[0041] Subsequently, the steam is released by pushing the stamping component 13 downward, and the steam quickly diffuses in the inner space of the molding component 12, and the molding component 12 after demolding is fully and efficiently disinfected; at the same time, as the stamping component 13 descends, the edible oil slowly flows downward along the inner wall of the molding component 12; and in this descending process, while pushing the moon cake to be demolded, the downward pressure can also deepen the printed pattern on the top of the moon cake;

[0042] When the stamping component 13 starts to rise, the edible oil on the inner wall of the molding component 12 is applied more evenly, so that in the subsequent mooncake demoulding process, it is possible to ensure that the various parts of the mooncake are evenly stressed, avoid partial detachment and partial residue caused by local adhesion, and allow the mooncake to be completely separated from the molding component 12; at the same time, when the stamping component 13 rises to the top, the edible oil leakage hole of the molding component 12 and the steam leakage hole of the stamping component 13 are blocked to prevent the edible oil from leaking in a non-working state, and ensure that the steam can be concentrated and effectively act on the inside of the molding component 12 when it needs to be released;

[0043] Among them, see Figure 3 , Figure 4 As shown, the direction indicated by the solid arrow is the pressing direction of the stamping component 13; the direction indicated by the hollow dashed arrow is the gas flow direction; and the direction indicated by the hollow solid arrow is the edible oil flow direction.

[0044] First, the specific structure of the molding assembly 12 is disclosed. The molding assembly 12 includes a bracket 123. The bracket 123 has guide columns 120 movably connected near the four corners. The guide columns 120 are fixedly connected to the top of the base 1. The tops of two adjacent guide columns 120 are fixedly connected to the top plates 121. The outer walls of the guide columns 120 are movably connected to guide sleeves 122. The guide sleeves 122 are fixedly connected to the bottom of the bracket 123. The inner walls of the bracket 123 near the two ends are fixedly connected to sliders 124. The slider 124 has a screw 125 movably connected inside. The screw 125 is fixedly connected to the top of the motor output shaft.

[0045] An oil tank 126 is fixedly connected to the center of the bracket 123, a guide tube 1260 is fixedly connected to the top of the oil tank 126, an oil pump is arranged at the end of the guide tube 1260, a mold 127 is fixedly connected to the bottom of the oil tank 126, a plurality of grooves at the bottom of the oil tank 126 are fixedly connected to the inside of each of the circulation parts 128, and a stamping assembly 13 is movably connected between the oil tank 126 and the inside of the mold 127;

[0046] See also Figure 2-Figure 5 As shown, the screw 125 is rotated by the rotation of the motor output shaft, so that the slider 124 moves up and down on the outer wall of the screw 125, and the bracket 123 and the guide sleeve 122 are driven to move up and down on the outer wall of the guide column 120 by the slider 124. The oil tank 126 is driven to move up and down by the bracket 123. The height of the mold 127 and the stamping assembly 13 is adjusted by the movement of the oil tank 126, so as to facilitate the moon cake material on the conveying device 11 to be introduced into the mold 127, thereby achieving accurate extrusion molding of the moon cake;

[0047] The guide post 120 ensures that the mold 127 and the mooncake material can be accurately aligned when the mold is closed, preventing the mold 127 from being offset or damaged during the stamping process, and the guide sleeve 122 forms a sliding fit with the guide post 120 to further ensure the mold closing accuracy and stability of the mold 127;

[0048] Secondly, the specific structure of the stamping assembly 13 is disclosed. The stamping assembly 13 includes a vacuum tube 132, which is fixedly connected to the inside of the oil tank 126. The end of the vacuum tube 132 passing through the oil tank 126 is fixedly connected to an air pipe 1320, and an evaporator is arranged at the end of the air pipe 1320. The top of the vacuum tube 132 passing through the oil tank 126 is fixedly connected to a cylinder 131, and a piston rod 1310 is movably connected inside the cylinder 131. The end of the piston rod 1310 passing through the inside of the vacuum tube 132 is fixedly connected to a baffle 1311, and the end of the baffle 1311 is fixedly connected to a printing piece 130, and the printing piece 130 is movably connected inside the mold 127.

[0049] See also Figure 3 , Figure 4 and Figure 7 As shown, the piston rod 1310 is driven up and down by the cylinder 131, and the baffle 1311 is driven downward by the piston rod 1310, so that the baffle 1311 drives the printing piece 130 downward, and when the printing piece 130 is descending, the circulation piece 128 is downward, so that the edible oil in the oil tank 126 can flow downward along the inner wall of the mold 127; and when the baffle 1311 and the printing piece 130 are downward, the steam in the air pipe 1320 passes through the vacuum tube 132 and enters the mold 127, and the mold 127 after demoulding is subjected to steam high-temperature sterilization, wherein the vacuum tube 132 is used to separate the steam and the oil tank 126, so as to prevent the steam from heating the edible oil in the oil tank 126; and as the printing piece 130 continues to descend, the moon cake in the mold 127 is pushed to be demoulded, and at the same time, the downward pressure applied during this descent can also deepen the printed pattern on the top of the moon cake;

[0050] The circulation member 128 includes a cone block 1280, and a plurality of cone blocks 1280 are respectively fixedly connected to the inside of a plurality of holes at the bottom of the oil tank 126. A hole plate 1283 is movably connected to the top of the cone block 1280, and a push rod 1282 is fixedly connected to the bottom of the hole plate 1283. A piston 1281 is fixedly connected to the outer wall of the push rod 1282 near the center, and the piston 1281 is movably connected to the inside of the cone block 1280.

[0051] See also Figure 6As shown, when the push rod 1282 loses its supporting force, the orifice plate 1283 and the piston 1281 are driven down by their own gravity, so that the piston 1281 moves out from the inside of the cone block 1280, and the orifice plate 1283 is supported on the top of the cone block 1280, so that the edible oil in the oil tank 126 passes through the holes of the orifice plate 1283 and the inside of the cone block 1280, and is poured onto the inner wall of the mold 127;

[0052] The printed part 130 includes a small flower plate 1300, which is fixedly connected to the bottom of the baffle 1311, and a large flower plate 1301 is fixedly connected to the bottom of the small flower plate 1300. A plurality of balls 1303 are movably connected between the large flower plate 1301 and the small flower plate 1300, near the edge of the large flower plate 1301, and a wreath 1302 is movably connected between the plurality of balls 1303.

[0053] See also Figure 8 As shown, when the piston rod 1310 drives the baffle plate 1311 upward to drive the printing piece 130 to move upward, the ball 1303 inside the printing piece 130 rubs against the inner wall of the mold 127, so that the ball 1303 rotates on the outer wall of the wreath 1302, which is convenient for evenly applying the edible oil on the inner wall of the mold 127, and is convenient for ensuring that all parts of the moon cake are evenly stressed during the subsequent demoulding process of the moon cake, avoiding partial detachment and partial residue caused by local adhesion; at the same time, because the diameter of the large flower plate 1301 is larger than that of the small flower plate 1300, when edible oil flows downward, it can more conveniently contact the outer wall of the ball 1303;

[0054] In addition, the printed part 130 continues to rise, driving the baffle 1311 to be re-blocked inside the vacuum tube 132, ensuring that the steam can be concentrated and effectively act on the inside of the mold 127 when released downward; at the same time, the printed part 130 pushes the push rod 1282 upward, so that the push rod 1282 drives the piston 1281 and the orifice plate 1283 upward, blocking the piston 1281 at the smallest opening of the groove of the cone block 1280, thereby preventing continuous leakage of edible oil.

[0055] In summary, the working principle of this solution is as follows:

[0056] In the process of making moon cakes, the screw 125 is firstly driven to rotate by the rotation of the motor output shaft, thereby enabling the slider 124 to move up and down on the outer wall of the screw 125, and the slider 124 drives the bracket 123 and the guide sleeve 122 to move on the outer wall of the guide column 120, so that the bracket 123 drives the oil tank 126 to move up and down accordingly; by adjusting the position of the oil tank 126, the height of the mold 127 and the stamping assembly 13 can be accurately adjusted, so that the moon cake material on the conveying device 11 is smoothly guided into the mold 127, so as to achieve accurate extrusion molding of the moon cake, and ensure that the shape and size of the moon cake meet the requirements;

[0057] Secondly, the piston rod 1310 is driven to move up and down by the cylinder 131. When the piston rod 1310 moves downward, the baffle plate 1311 and the printing piece 130 are driven downward together. When the printing piece 130 descends, the top rod 1282 loses the supporting force of the printing piece 130, causing the orifice plate 1283 and the piston 1281 to descend under the action of their own gravity. At this time, the piston 1281 moves out from the inside of the cone block 1280, and the orifice plate 1283 is supported on the top of the cone block 1280. In this way, the edible oil in the oil tank 126 can pass through the holes of the orifice plate 1283 and the inside of the cone block 1280, and sprinkle on the inner wall of the mold 127, so that the edible oil in the oil tank 126 can smoothly flow downward along the inner wall of the mold 127, providing good lubrication conditions for the demoulding and subsequent processing of the moon cakes.

[0058] At the same time, when the baffle 1311 and the printing member 130 move downward, the steam inside the air pipe 1320 passes through the vacuum tube 132 and then enters the interior of the mold 127, and performs steam high-temperature sterilization on the mold 127 after demolding; as the printing member 130 continues to descend, the moon cake inside the mold 127 is pushed to be demolded; and in this descending process, the downward pressure exerted by the printing member 130 further deepens the printed pattern on the top of the moon cake, making the printing clearer and more beautiful, thereby improving the quality and artistic value of the moon cake;

[0059] When the piston rod 1310 moves upward, driving the baffle 1311 and the printing piece 130 upward, the ball 1303 inside the printing piece 130 will rub against the inner wall of the mold 127; in this process, the ball 1303 rotates on the outer wall of the wreath 1302, so as to evenly apply the edible oil on the inner wall of the mold 127, ensuring that in the subsequent mooncake demoulding process, all parts of the mooncake are evenly stressed, avoiding partial detachment and partial residue caused by local adhesion, so that the mooncake can be completely separated from the mold 127;

[0060] In addition, as the printed part 130 continues to rise, it will also drive the baffle 1311 to re-block the inside of the vacuum tube 132, ensuring that the steam can be concentrated and effectively act on the inside of the mold 127 when it is released next time, thereby improving the efficiency and effect of steam sterilization; at the same time, the upward movement of the printed part 130 will also push the push rod 1282, so that the push rod 1282 drives the piston 1281 and the orifice plate 1283 upward, blocking the piston 1281 at the smallest opening of the groove of the cone block 1280, thereby effectively preventing the continuous leakage of edible oil, avoiding waste and pollution to the working environment.

[0061] Example 2

[0062] See also Figure 3 , Figure 4 and Figure 6 As shown, in the use of the printing device for mooncake processing in the present application, when it is necessary to process Cantonese mooncakes, since Cantonese mooncakes are known for their thin skin and large fillings, the fillings account for a high proportion. During the demoulding process, the mold 127 needs to be able to withstand greater pressure; for some molds 127 with softer materials, such as silicone materials, sufficient support may not be provided, which may easily cause the mooncakes to collapse or deform during demoulding;

[0063] Therefore, by setting the printing piece 130 and the mold 127 to be made of metal, according to the material characteristics of high strength, the printing piece 130 and the mold 127 can withstand greater pressure and impact during the mooncake production process, ensuring that the mold 127 and the printing piece 130 are not easily deformed or damaged during long-term use, and maintain a stable shape and structure. They can withstand greater pressure during the stamping process to avoid cracking or collapse, thereby ensuring the molding quality of the mooncakes;

[0064] Secondly, the motor output shaft rotates to drive the screw 125 to rotate, so that the slider 124 moves up and down on the outer wall of the screw 125, thereby driving the bracket 123 and the guide sleeve 122 to move up and down on the outer wall of the guide column 120. The up and down movement of the bracket 123 drives the oil tank 126 to move, and the height of the mold 127 and the stamping assembly 13 is adjusted, so that the mooncake material on the conveying device 11 is introduced into the mold 127, so as to realize the precise extrusion molding of the mooncake;

[0065] The piston rod 1310 is driven up and down by the cylinder 131, and the piston rod 1310 drives the baffle 1311 and the printing member 130 downward to push the moon cake to be demoulded and deepen the printed pattern on the top of the moon cake. When the printing member 130 descends, the circulation member 128 is also moved downward, so that the edible oil in the oil tank 126 flows downward along the inner wall of the mold 127. When the piston rod 1310 drives the baffle 1311 upward to drive the printing member 130 upward, the ball 1303 inside the printing member 130 rubs against the inner wall of the mold 127, so that the ball 1303 rotates on the outer wall of the wreath 1302, so that the edible oil on the inner wall of the mold 127 is evenly applied.

[0066] When processing Cantonese-style mooncakes, edible oil can be made to stick to the surface of the mooncakes to form a thin oil film, making the mooncakes look brighter, making the color of the mooncakes more uniform, avoiding the situation where the color is too dark or too light in some parts, and improving the overall aesthetics of the mooncakes; and to a certain extent, adding a light oil aroma to the mooncakes, enriching the taste of the mooncakes.

[0067] Example 3

[0068] See also Figure 3 , Figure 4 and Figure 6As shown, in the use of the printing device for mooncake processing in the present application, when it is necessary to process Su-style mooncakes, since the characteristic of Su-style mooncakes is their layers of crispy pastry, and the pastry is composed of multiple layers of thin dough and grease alternately, the texture is very fragile; since the friction between the metal mold 127 and the pastry is small, the mooncake is easy to deform when demolding, and Su-style mooncakes usually have a specific shape, such as round, square, etc., the metal mold 127 may not be able to keep the shape of the mooncake stable during the demolding process, so that the mooncake appears skewed, flat or irregular.

[0069] Therefore, the piston rod 1310 is driven to move up and down by the cylinder 131; when the piston rod 1310 moves downward, the baffle plate 1311 and the printing piece 130 are driven downward, so that the top rod 1282 loses its supporting force, the orifice plate 1283 and the piston 1281 descend under the action of gravity, the piston 1281 moves out of the cone block 1280, the orifice plate 1283 is supported on the top of the cone block 1280, and the edible oil in the oil tank 126 is sprinkled on the inner wall of the mold 127; when the piston rod 1310 moves upward, the baffle plate 1311 and the printing piece 130 are driven upward, the ball 1303 in the printing piece 130 rubs the inner wall of the mold 127, and the ball 1303 rotates on the outer wall of the wreath 1302, and the edible oil on the inner wall of the mold 127 is evenly applied;

[0070] When processing the Su-style mooncakes, a thin protective film can be formed between the mooncake crust and the mold 127, reducing the direct contact between the crust and the mold 127, and increasing the lubricity of the mold 127, so that when the mooncake is formed in the mold 127 and needs to be demolded, the lubricated surface can reduce the friction between the mooncake and the mold 127, making it easier for the mooncake to be removed from the mold 127, and reducing the risk of the crust being scratched or damaged; at the same time, a proper amount of edible oil can add a light fragrance and taste to the Su-style mooncakes. During the baking process, the edible oil will interact with the crust and fillings of the mooncake, making the mooncake more crispy and delicious, and helping to retain the moisture of the mooncake, preventing the mooncake from being too dry during storage and affecting the taste.
