Description

Technical Field

[0001] This application relates to the field of food production equipment technology, specifically to a synchronous embossing and decal device for food. Background Technology

[0002] The appearance decoration of food products (such as steamed buns, glutinous rice balls, and other pastries) is an important means to enhance product added value and increase consumer appeal. Among them, embossing and decal techniques are key processes for achieving patterned and artistic surface treatments. Traditional pastry decoration mostly relies on manual operations, such as forming textures or patterns on the surface of dough through mold pressing, hand carving, or drawing. However, this method is inefficient, inconsistent, and requires high skill levels from operators, making it difficult to adapt to the needs of large-scale production.

[0003] With the increasing automation of the food industry, mechanical decal technology is gradually being applied to food production. For example, a patent document with publication number CN222997289U disclosed a pastry decal forming device, which extrudes and cuts decorative dough sheets into shape by pressing and cutting dough strips, and then attaches them to the surface of pastries to achieve decal decoration. However, in the process of implementing the technical solution in the embodiments of this application, the inventors of this application found that the dough sheets formed and attached by the above-mentioned pastry decal forming device only have decorative outlines and cannot emboss decorative patterns on the decorative dough sheets, thus limiting the decorativeness of the dough sheets.

Summary of the Invention

[0006] According to one aspect of this disclosure, a synchronous embossing and appliqué device for food is provided, comprising a dough conveyor belt perpendicular to and mounted above the dough conveyor belt, an embossing mechanism and a cutting and appliqué mechanism sequentially mounted above the dough conveyor belt along the running direction of the dough conveyor belt; the dough conveyor belt includes a plurality of synchronous belts evenly spaced, a plurality of dough-pulling belts that move synchronously with the synchronous belts and are located upstream of the cutting and appliqué mechanism and respectively between the synchronous belts, and anti-sticking plates located on the upstream and downstream sides of the cutting and appliqué mechanism corresponding to the gaps between the synchronous belts; the embossing mechanism includes an embossing cylinder corresponding to... The conveyor belt includes several embossed plates arranged in an array, with support blocks positioned directly below each embossed plate on the bearing surface of the noodle conveyor belt. The cutting and pasting mechanism includes several punching heads driven by a cutting cylinder and arranged in the same array as the embossed plates, punching dies positioned between the synchronous belts and directly below each punching head, and air outlets connected to a pressurized air source on both sides of each punching die. The distance between the embossed plates and the punching heads in the same array position is an integer multiple of the stepping distance of the noodle conveyor belt. The cutting and pasting mechanism is positioned above the noodle conveyor belt.

[0007] In some embodiments of this disclosure, the noodle conveyor belt further includes a stepper motor for driving the synchronous belt to step, a pulley fixed to the same roller shaft for driving the synchronous belt, and a driven pulley for driving the noodle belt.

[0008] In some embodiments of this disclosure, the downstream end of the synchronous belt and / or the noodle belt is provided with a scraper plate that contacts the corresponding belt.

[0009] In some embodiments of this disclosure, the anti-adhesion plate is a strip plate and matches the gap profile between the synchronous belts on both upstream sides of the cutting and pasting mechanism.

[0010] In some embodiments of this disclosure, the embossing mechanism further includes an embossing pad plate that is fixed relative to the conveyor belt frame and located between the carrying section and the return section of the synchronous belt, with each of the support blocks arranged in an array on the top surface of the embossing pad plate.

[0011] In some embodiments of this disclosure, the cutting and pasting mechanism includes a base plate that is relatively fixed between the synchronous belt carrying section and the return section, and each of the punching dies is arranged in an array on the base plate.

[0012] In some embodiments of this disclosure, the air outlet is arranged perpendicular to the conveying direction of the face belt, and the air outlet includes an air outlet body, an air outlet cavity opened in the air outlet body, and an air inlet communicating with the air outlet cavity; a plurality of air outlet holes communicating with the air outlet cavity are correspondingly opened at the air outlet body within the gap range between each synchronous belt.

[0013] In some embodiments of this disclosure, the cutting and pasting mechanism further includes a cutting head outer mold that is fixed relative to the frame of the cutting and pasting mechanism and has a cutting head air cavity inside. The cutting head outer mold has a cutting hole at the position of each punching cutting head for embedding the corresponding punching cutting head and communicating with the cutting head air cavity. Each punching cutting head has a plurality of cutting head air holes at the end face for punching the dough strip that are respectively connected with the cutting head air cavity.

[0014] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. The embossing mechanism and the cutting and pasting mechanism are arranged sequentially from upstream to downstream along the running direction of the conveyor belt.

[0024] 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.

[0025] Unless otherwise specified, all devices and other components involved in the following embodiments are commercially available products.

[0026] 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.

[0027] To enable simultaneous embossing and decal application processes, thereby improving food production efficiency and decorative effect, this example discloses a simultaneous embossing and decal application device for food. (See attached image.) Figure 1 The device includes a dough conveyor belt 1 positioned above the dough conveyor belt (not shown in the figure) with its running direction perpendicular to the dough conveyor belt. An embossing mechanism 2 and a cutting and pasting mechanism 3 are sequentially mounted above the dough conveyor belt from upstream to downstream along its running direction. Thus, when the pressed and shaped dough strip runs along the dough conveyor belt 1, the embossing mechanism 2 first imprints decorative patterns on the surface of the dough strip. Then, the cutting and pasting mechanism 3 presses the areas of the dough strip with the embossed decorative patterns into decorative sheets of the corresponding shapes. After pressing, the shaped decorative sheets are further pressed down and pasted onto the food to be decorated at the dough conveyor belt, thereby achieving the technical effect of simultaneous embossing and pasting operations.

[0028] Specifically, in this embodiment, see Figure 2To achieve reliable conveying of the face belt, in this example, the face belt conveyor 1 includes several synchronous belts 11 arranged at equal intervals. Among them, Figure 1 The conveyor belt shown includes four synchronous belts 11. Each synchronous belt 11 includes a synchronous belt body and a pulley 12 that drives the synchronous belt body to rotate cyclically. The inner surface of the synchronous belt body and the outer surface of the pulley 12 are respectively provided with matching teeth to prevent slippage between the synchronous belt body and the pulley, which would affect the stepping distance of the synchronous belt body. In addition, in this example, the conveyor belt 1 also includes a stepper motor 13 for driving the synchronous belts 11 to step, thereby realizing the equal-interval stepping of the synchronous belts 11. This allows the embossing mechanism 2 and the cutting and pasting mechanism 3 to perform embossing and stamping operations on the surface belt during the stepping intervals of the synchronous belts 11.

[0029] In this embodiment, considering that the surface of the synchronous belt 11 used to contact the face belt is relatively smooth and it is difficult to form sufficient friction with the face belt to pull the face belt into the face belt conveyor belt, in this example, the face belt conveyor belt 1 also includes several face belts 14 arranged upstream of the face belt conveyor belt 1. See details below. Figure 2 In this example, each noodle belt 14 is positioned in the gap between each synchronous belt 11, and the surface of the noodle belt 14 that contacts the noodle belt is rougher than that of the synchronous belt 11, thereby increasing the friction between them. This provides a certain pulling force for the noodle belt to enter the conveyor belt through its own movement. Furthermore, to ensure that the noodle belt 14 rotates synchronously with the synchronous belt 11, in this embodiment, see... Figure 3 A driven wheel 15 for driving the noodle belt 14 is fixedly installed outside a roller shaft with several pulleys fixed at equal intervals. Thus, the synchronous rotation of the synchronous belt 11 and the noodle belt 14 is achieved through the synchronous rotation of the driven wheel 15 and the pulleys.

[0030] See Figure 1 An embossing mechanism 2 is installed above the running range of the ramen belt 14. Specifically, in this embodiment, see... Figure 4The embossing mechanism 2 is fixed relative to the frames on both sides of the conveyor belt via an embossing frame 21, and an embossing cylinder 22 is fixedly mounted on the top of the embossing frame 21. Furthermore, in this example, the embossing mechanism 2 also includes several embossing plates 23, arranged in a specific array. The end face of each embossing plate 23 that contacts the conveyor belt has corresponding textures, facilitating pressing down under the drive of the embossing cylinder 22 to achieve embossing on the surface of the conveyor belt. To achieve synchronous pressing of each embossing plate 23, in this embodiment, each embossing plate 23 is arranged in a relatively fixed array at the embossing action plate 24, which is driven by the embossing cylinder 22. Thus, during the embossing operation, the embossing cylinder 22 extends accordingly, driving the embossing action plate 24 to press down, thereby causing each embossing plate 23 to descend synchronously, achieving synchronous embossing operation of each embossing plate 23. In addition, considering that the thickness of the dough is not absolutely uniform in different places, in order to effectively adapt to the thickness of the dough at different positions, in this example, each embossing plate 23 is fixedly provided with a plate shaft passing through the embossing action plate 24. The top of the plate shaft is provided with a limiting sleeve 25, and an embossing spring 26 is provided on the plate shaft. One end of the embossing spring 26 abuts against the embossing plate 23, and the other end abuts against the embossing action plate 24. Thus, when the embossing action plate 24 is pressed down, the embossing spring 26 of each embossing plate 23 can deform to different degrees according to the thickness of the dough at the position below it, so that the embossing at different thickness positions of the dough can achieve the same degree of embossing, avoiding the problem of uneven texture where the embossing pattern is deeper at the position of the dough that is too thick and shallower at the position of the dough that is too thin.

[0031] Furthermore, considering that the ramen belt 14 has limited supporting force and cannot effectively support the belt during the printing operation of the embossing plates 23 of the embossing mechanism, a support block is provided below the bearing surface of the ramen belt 14 in this embodiment. See Figure 3 To reduce unnecessary friction between the support blocks and the ramen belt 14, in this embodiment, each support block 27 is only located directly below each embossed plate 23. Specifically, to achieve a stable installation of each support block 27, see [link to relevant documentation]. Figure 3 In this example, an embossed pad 28 is fixedly installed between the frames of the noodle conveyor belt, and the embossed pad 28 is specifically located between the carrying section and the return section of the synchronous belt. In addition, each support block 27 is fixedly installed at the embossed pad 28 and the array position corresponds one-to-one with the array position of each embossed plate 23, thereby providing effective support for the noodle belt 14 through the support blocks 27.

[0032] In this example, a scraper plate is provided at the downstream end of the synchronous belt 11 and the noodle belt 14, which is in contact with the corresponding belt. Taking the scraper plate 16 downstream of the noodle belt 14 as an example, the scraper plate 16 is fixed at the tail position of the noodle belt 14 in an inclined shape, and one end of it is in tangential contact with the noodle belt 14, thereby scraping off the noodle residue remaining on the surface of the noodle belt 14, and the scraped noodle residue falls along the inclined scraper plate 16 into the slag collection box on the other side of the scraper plate for collection.

[0033] After the dough strip undergoes embossing by embossing mechanism 2, it enters the cutting and appliqué mechanism 3 for stamping and appliqué. See details... Figure 3 and Figure 1 In this example, since the noodle conveyor belt is only located upstream of the noodle conveyor belt at the position corresponding to the embossing mechanism, after the noodle belt undergoes the embossing operation and detaches from the noodle conveyor belt 14 along with the synchronous belt 11, there is a risk that the noodle belt within the gap range of each synchronous belt 11 may sag and get caught in the synchronous belt 11 due to its own weight. Therefore, in this embodiment, smooth anti-sticking plates 17 are arranged upstream and downstream of the cutting and pasting mechanism 3, corresponding to the gap range between each synchronous belt 11. In this example, the anti-sticking plates are strip-shaped plates, and the anti-sticking plates 17 effectively support the movement of the noodle belt in areas other than the noodle conveyor belt.

[0034] See Figure 5 The cutting and pasting mechanism 3 includes a cutting cylinder 31 as a cutting and pasting power source. A cutting and pasting action plate 32 is fixedly mounted on the actuating end of the cutting and pasting cylinder 31. A plurality of punching blades 33 are arrayed at the bottom of the cutting and pasting action plate 32. The cutting and pasting cylinder 31 is fixedly mounted at the top of the cutting and pasting mechanism frame. (See attached image.) Figure 1 The base plate of the cutting and pasting mechanism frame is located between the synchronous belt carrying section and the return section. In addition, a number of punching dies 34 are arrayed on the base plate of the cutting and pasting mechanism frame. The array position of each punching die 34 is the same as the array position of each punching head 33 and corresponds one-to-one. The punching die 34 has a cutting hole that matches the outer contour of the punching head 33. Thus, after the textured surface tape steps to the position of the punching die 34, the cutting cylinder 31 extends, causing the cutting action plate 32 to press down, thereby driving each punching head 33 into the cutting hole of each punching die 34. The stamping and shearing of the surface tape by the edge of the punching head 33 and the edge of the punching die 34 realizes the stamping and forming of the decorative surface tape.

[0035] In this embodiment, to ensure accurate stamping of the embossing area on the dough by the cutting and pasting mechanism 3, the array positions of each punching head 33 coincide with and correspond one-to-one with the array positions of each embossing plate 23 of each embossing mechanism. Furthermore, the distance between the embossing plates with the same array position and the punching heads is set to an integer multiple of the dough conveyor belt's stepping distance, thereby ensuring that the embossing area on the dough can accurately step to the corresponding punching head for stamping. After the decorative dough is stamped, the punching heads 33 are further driven to continue pressing down. Since the cutting and pasting mechanism 3 is located above the dough conveyor belt in this example, the placement position of the dough to be decorated on the dough conveyor belt is adjusted to match the array of punching heads. With the simultaneous stepping of the dough conveyor belt and the dough conveyor belt, the downward pressure of the punching heads 33 accurately adheres the decorative dough to the surface of the dough to be decorated, achieving the effect of punching and pasting. In this embodiment, see... Figure 5 The end face of the punching head 33 is a three-dimensional curved surface, which can realize the three-dimensional forming of the decorative surface after punching, so that it is attached to the surface to be decorated in a certain arc shape.

[0036] Furthermore, considering that the dough strip experiences direct friction with the punching die 34 of the cutting mechanism as it passes through the cutting mechanism 3, and that the dough strip's adhesion to the cutting mechanism components is aggravated by the force exerted when the punching head 33 is pressed down, this example provides air blowers 35 connected to a pressurized air source on both sides of each punching die. Specifically, the air blowers 35 are fixed to the base plate of the cutting mechanism 3 along a direction perpendicular to the dough strip conveying direction. Each air blower 35 includes an air blower body and an air blower cavity formed inside the air blower body, with an air inlet on one side of the air blower cavity. In this example, threaded holes are provided on both sides of the cutting mechanism side plate, and air pipe connectors are installed to connect the air pipe to the air blower inlet, facilitating the injection of pressurized gas into the air blower cavity. In addition, the air exhaust body has several air exhaust holes in the area corresponding to the gap between each synchronous belt on the top surface of the contact surface belt. Pressurized gas is blown out through each air exhaust hole to prevent the surface belt from sticking to the punching die.

[0037] In other embodiments, to prevent the decorative dough from sticking to the punching head when it pushes the stamped decorative dough onto the food to be decorated, a number of air holes are provided on the end face of the punching head that contacts the dough. Specifically, in this example, a cutter head outer mold is provided below the cutting action plate of the cutting mechanism and is fixed relative to the frame of the cutting mechanism. The cutter head outer mold has an array of cutter holes corresponding to the positions of each punching head, and an outer mold air cavity communicating with each cutter hole is provided inside the cutter head outer mold. Furthermore, in this example, each punching head is connected to the cutting action plate via a connecting rod. The top outer edge of each cutter hole matches the outer edge contour of the connecting rod, and the bottom outer edge contour of each cutter hole matches the outer edge contour of the punching head, thereby achieving relative closure of the cutter holes, so that the pressurized gas in the outer mold air cavity can only be discharged through the air holes at each punching head. Furthermore, during the decal application process, pressurized air is introduced into the outer mold cavity, and then the pressurized air is discharged from the air holes at each punching head, thereby separating the decorative surface from the punching head and preventing adhesion.
