Description

Technical Field

[0001] The utility model relates to the technical field of cake processing, in particular to a cake surface grouting system. Background Art

[0002] Cakes are a type of sweet food made from flour, sugar, oil, eggs, etc., through baking, steaming, frying, etc. They play an important role in food culture around the world, with a wide variety of flavors, and can be used as daily snacks or as delicacies for festivals or special occasions.

[0003] When making pastries, the selection and proportion of raw materials, mixing and fermentation techniques, baking temperature and time, etc. will have an important impact on the final taste and texture of the pastries. Chinese pastries are famous for their fine craftsmanship and rich variety of fillings, such as moon cakes, while Western pastries are popular for their exquisite appearance and diverse flavors, such as biscuits, and Japanese pastries are mainly wagashi.

[0004] In order to ensure that the edible texture, taste, and appearance of pastries are in the most satisfactory state, Japanese, Chinese, and Western pastries are integrated to make the pastries have the attractive appearance of Japanese pastries and the rich and delicious taste and texture of Chinese pastries. In the prior art, the combination of Japanese and Chinese pastries is relatively mature, but there is an obvious problem with this combined pastry, that is, in order to ensure that the pastry can retain the beauty of Japanese pastries, its dough is usually thicker to facilitate the shaping of the pastry, and also to prevent it from cracking and revealing the fillings therein, so its dough is not as thick as Japanese pastries. Western-style pastries have a good taste, usually maintaining a relatively bland taste, and must be eaten with fillings. Now it is necessary to combine the jam biscuits in Western-style pastries with the Chinese-Japanese combination pastries, so that the pastries have the advantages of the three parties at the same time. However, there is no system in the prior art that can combine the production of the three kinds of pastries. Most of them still require a pastry chef with certain experience to operate before they can be put into production. However, relying on the operation of the pastry chef, they can only be supplied to a single store for sale on the same day, and cannot be put into the market in batches for sale, and do not have satisfactory production efficiency.

[0005] Therefore, a pastry surface grouting system is proposed to solve or alleviate the above problems. Utility Model Content

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. 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.

[0039] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0040] A pastry surface injection system, such as Figure 1 As shown, it includes a rotating structure, a pressing structure, and a sauce injection structure;

[0041] There are at least four workstations on the rotary structure, which include a loading station, a molding station, a sauce injection station, and a material unloading station in sequence;

[0042] The pressing structure is located above the rotary structure, and presses down the rough pastry embryo moved to the pressing station to form a convex pattern 29 on its top surface;

[0043] The sauce injection structure is located above the rotary structure, and the jam is squeezed into the concave portion 30 formed between the lines 29 on the top surface of the rough pastry embryo at the sauce injection station.

[0044] The setting of the rotary structure is not limited to rotation in the vertical direction, but is also applicable to rotation in the horizontal direction, driving the rough pastry to rotate, so that the workstation can rotate, so that the operator can load and unload the rough pastry in the process, and in the process of loading and unloading the rough pastry, it can also cooperate with the pressing structure to press the rough pastry downward to press it into a desired shape structure, and can also make the top surface of the rough pastry press out upwardly protruding lines 29, and recessed areas 30 can be formed between the lines 29 for subsequent injection. The jam structure squeezes the jam into the recess 30 to fill up the space in the recess 30. It should be noted that the jam is not limited to a certain type, such as blueberry jam, strawberry jam, or other jams. After the jam is injected, the rough pastry can be fed into the subsequent processing steps, such as baking, to obtain the finished pastry. Through the setting of this system, the automated mass production of Chinese, Japanese and Western-style combined pastries can be realized, which greatly improves the production efficiency of this type of special pastries to meet the needs of large production.

[0045] Preferably, if Figure 2 As shown, the rotary structure includes a plurality of mounting plates 6 and a lower mold detachably connected to the mounting plates 6;

[0046] A plurality of mounting plates 6 are displaced to form a loop, and the loading station, the pressing station, the sauce injection station, and the unloading station are all formed by a mounting plate 6 in the loop.

[0047] The mounting plate 6 is used as a carrier to carry the lower mold, and the mounting plate 6 rotates to form a loop, driving the lower mold to move on the loop, and the lower mold will pass through the loading station, the pressing station, the sauce injection station, and the unloading station in sequence. At each station, the lower mold needs to cooperate to achieve different effects. For example, the lower mold on the loading station realizes the carrying of the rough pastry embryo, the lower mold on the pressing station realizes the action of cooperating in the pressing and molding of the rough pastry embryo, the lower mold on the sauce injection station realizes the limiting and positioning of the rough pastry embryo, so that the sauce injection structure can inject the jam into the recessed area 30 on the top surface of the rough pastry embryo, and the lower mold on the unloading station cooperates to realize the effect of demoulding, positioning and dropping the rough pastry embryo after the sauce injection.

[0048] Preferably, if Figure 1 As shown, the rotary structure also includes two frames 1, a bearing seat 2, a rotating shaft 3, a sprocket 4, and a chain 5;

[0049] The rack 1 is arranged vertically;

[0050] The bearing seat 2 is fixedly connected to both ends of the frame 1;

[0051] Both ends of the rotating shaft 3 pass through the frames 1 on both sides and are fixedly connected to the inner ring of the bearing seat 2;

[0052] The sprocket 4 is fixedly connected to both ends of the rotating shaft 3;

[0053] The chain 5 is connected to the sprocket 4 provided at the same end of the rotating shaft 3 on both sides;

[0054] The mounting plate 6 is rotatably connected to the chain plates in the chain 5 .

[0055] The rotating structure drives the mounting plate 6 and the lower mold to move and rotate. The servo motor is fixed on the frame 1 on one side, and the output shaft of the servo motor is connected to one end of one of the rotating shafts 3 through a coupling, so that one of the rotating shafts 3 starts to rotate. The rotation of any rotating shaft 3 will drive the sprocket 4 on it to rotate. Under the support of the bearing seat 2, the rotating shaft 3 can not only rotate smoothly, but also be stably installed on the frame 1. The rotation of the rotating shaft 3 on one side drives the rotation of the sprocket 4, and the sprocket 4 will drive the sprocket 4 and the rotating shaft 3 on the other side to rotate through the chain 5, so that the chain 5 can rotate. When the chain 5 rotates, the mounting plate 6 connected to the chain plate can also rotate together, which will not hinder the rotation of the chain 5 and avoid jamming.

[0056] Preferably, if Figure 1 and 3As shown, the pressing structure includes a driving assembly, a movable plate 32 fixedly connected to the movable end of the driving assembly, and an upper mold detachably connected to the bottom surface of the movable plate 32. The driving assembly drives the movable plate 32 to move back and forth.

[0057] The driving component can adopt a variety of structures, as long as it can realize the reciprocating movement of the movable plate 32 in the vertical direction. In this solution, the driving component is set in the form of a cylinder 14, but it is not limited to the cylinder 14, and other structures that can achieve the same function can also be used to replace it.

[0058] The driving assembly is installed on the top plate 13, and vertically arranged columns 12 are fixedly connected on both sides of the length direction of the bottom surface of the top plate 13. The two sides of the two frames 1 that are away from each other are fixedly connected to a mounting frame 11 with an inverted L-shaped cross-section, and the lower end of the column 12 is fixedly connected to the mounting frame 11, thereby ensuring that the profiled structure can always be located above the rotating structure.

[0059] The driving assembly drives the upper mold to move back and forth by driving the movable plate 32. When the upper mold moves downward, the upper mold can cooperate with the lower mold located on the pressing station to press the rough pastry in the lower mold to form a rough pastry of the required shape. The top surface of the rough pastry can also form upwardly protruding lines 29, and recessed areas 30 are formed between the lines 29 to pave the way for the subsequent jam injection structure to inject jam.

[0060] Preferably, if Figure 3 As shown, the press-forming structure also includes a pre-positioning component, and a positioning column 8 that cooperates with the pre-positioning component is fixedly connected to the mounting plate 6. The pre-positioning component is arranged on the movable plate 32, and when the movable plate 32 moves toward the mounting plate 6, the pre-positioning component combines with the positioning column 8 before the upper mold and the lower mold combine.

[0061] The pre-positioning component moves downward with the movable plate 32, but before the movable plate 32 drives the upper mold and the lower mold to cooperate, the pre-positioning component will first press the positioning column 8 on the mounting plate 6, so that the mounting plate 6 remains relatively stable and not prone to deviation and shaking, and then the upper mold with a large force is pressed down to make the upper mold and the lower mold close together, and then complete the pressing process of the rough pastry. This ensures that the upper mold and the lower mold can be completely closed, avoiding the appearance of flaws in the shape of the final rough pastry, so as to avoid the subsequent sauce injection operation causing the position of the recessed part 30 on the top surface of the rough pastry to not correspond to the originally set coordinates, thereby causing the jam to flow out, and also reducing the implementation burden for the subsequent sauce injection structure to inject sauce, without the need for image recognition and other operations that excessively increase technical difficulty and cost.

[0062] Preferably, if Figure 3As shown, the pre-positioning assembly includes a lower pressure column 17, a limiting plate 18, a limiting sleeve 20, and an elastic member;

[0063] The lower pressure column 17 is arranged through the movable plate 32, and a positioning groove cooperating with the positioning column 8 is provided on its bottom surface;

[0064] The limiting plate 18 is fixedly connected to the upper end of the lower pressing column 17 , and the elastic member is sleeved on the outer ring of the lower pressing column 17 and is between the limiting plate 18 and the movable plate 32 .

[0065] The limiting sleeve 20 is integrally formed at the lower end of the lower pressure column 17, and the elastic member is also sleeved on the outer side of the lower pressure column 17 between the lower side of the movable plate 32 and the limiting sleeve 20. The upper elastic member can be an upper spring 19, and the lower elastic member can be a lower spring 21. The lower spring 21 has a compression resistance effect, and the upper spring 19 has a tensile resistance effect. Of course, the elastic member can also adopt other structures with elastic deformation properties, such as rubber sleeves, etc., as long as they can achieve the same function as the upper spring 19 and the lower spring 21.

[0066] The setting of the elastic member enables the lower pressure column 17 to move downward together with the movable plate 32. After the lower pressure column 17 cooperates with the positioning column 8, the lower spring 21 can be pressed down by the movable plate 32, and the upper spring 19 can be pulled down by the movable plate 32, so that the two can accumulate greater elastic potential energy, so that when the driving component drives the movable plate 32 to move upward, the pre-positioning component can move upward together and return to its original position.

[0067] Preferably, the positioning column 8 includes a cylindrical portion 9 and a conical portion 10 located at the upper end thereof, and the positioning groove is conical.

[0068] The cylindrical portion 9 is provided to prevent the downward pressure column 17 from directly pressing down on the mounting plate 6, and the conical portion 10 and the conical positioning groove are cooperated so that even if there are some deviations in orientation, they can be wedged together under the guidance of the inclined surfaces of the two, so that the pre-positioning component cooperates with the positioning column 8 to pre-position the mounting plate 6, so as to keep the mounting plate 6 in a more stable and firm state when it is located at the pressing station to meet the impact of the upper mold.

[0069] Preferably, if Figure 1 As shown, the sauce structure includes a space adjustment component and a glue dispenser 27;

[0070] The glue dispenser 27 is disposed on the movable end of the space adjustment component, and the space adjustment component drives the glue dispenser 27 to move within the three-dimensional space.

[0071] The space adjustment component drives the glue dispensing machine 27 to move between fixed points in three-dimensional space, so that the glue dispensing machine 27 only needs to follow the space adjustment component to always and constantly inject sauce into the depressions 30 on the top surface of the rough pastry. The cooperation between the pre-positioning component and the upper mold and the lower mold ensures that the rough pastry will maintain a fixed position at the depression 30 after pressing, and the pressing station is also in the same fixed position. Therefore, at this time, the glue dispensing machine 27 only needs to follow the space adjustment component to repeatedly move to several positions and inject sauce at these positions to realize the sauce injection process for the top surface of the rough pastry.

[0072] Preferably, if Figure 1 As shown, the space adjustment assembly includes a longitudinal displacement member, a lateral displacement member, and a vertical displacement member;

[0073] The transverse displacement member is arranged on the movable end of the longitudinal displacement member;

[0074] The vertical displacement member is arranged on the movable end of the horizontal displacement member;

[0075] The glue dispenser 27 is arranged on the movable end of the vertical displacement member.

[0076] The longitudinal displacement member is a longitudinal slide rail 22, a slide plate 23 slidably connected in the longitudinal slide rail 22, and a screw nut structure that drives the slide plate 23 to slide in the longitudinal slide rail 22. Both ends of the slide plate 23 pass through the longitudinal slide rail 22 and are fixedly connected to a gantry 24. The lateral displacement component, which is actually a lateral electric slide rail 25, is fixedly connected to the gantry 24. The vertical displacement member, which is actually a vertical electric slide rail 26, is fixedly connected to the slide seat of the lateral electric slide rail 25. The glue dispenser 27 is fixedly connected to the slide seat of the vertical electric slide rail 26. The longitudinal displacement member, the lateral displacement member, the vertical displacement member, and the glue dispenser 27 are coupled together with a controller to achieve control over the four.

[0077] Preferably, it also includes a blowing component, which is arranged on the unloading station and blows and demoulds the sauce-filled cakes that arrive at the unloading station.

[0078] Once the rough pastry is pressed in the upper and lower molds, even if the upper mold is quickly demoulded from the rough pastry under the drive of the driving component, the lower mold has to continue to support the rough pastry and cannot be demoulded from the rough pastry, and may even stick to it. The blowing component pumps outside air into between the lower mold and the rough pastry, and separates the two under the action of air pressure, so that the rough pastry can be demoulded in the lower mold, making it convenient for the operator to unload the rough pastry.

[0079] Preferably, the blowing assembly comprises an air jet tube and an air pump;

[0080] The lower mold is provided with a channel connected to the interior thereof, and the channel is connected to the injection pipe;

[0081] The air pump is connected to the air jet pipe.

[0082] Specifically, a through hole connected to the upper channel of the lower mold can also be opened on the mounting plate 6. As long as the mounting plate 6 can maintain a fixed position when it is moved to the unloading station, the nozzle of the jet pipe can always remain connected to the through hole. When the air pump works to draw outside air into the jet pipe, the jet pipe can pump air into between the rough pastry and the lower mold through the through hole and the channel in sequence, and then the rough pastry can be taken out of the lower mold by the air without damaging the shape of the rough pastry, thereby ensuring the integrity of the appearance of the rough pastry after demolding.

[0083] like Figure 4 As shown, the final pastry rough dough is a cake body 28 , the top surface of the cake body 28 is depressed downward to form a depression 30 , the top surface of the cake body 28 between the depressions 30 forms lines 29 , and the depressions 30 are filled with jam pieces 31 .

[0084] The utility model only needs to assemble appropriate upper and lower molds in actual working process, and place the rough pastry embryo after wrapping the filling with dough into the lower mold, so that it is displaced to the bottom of the pressing structure in the loop to be pressed into the required pastry shape, and outwardly protruding lines 29 are pressed on the top surface of the pastry, and depressions 30 for accommodating jam are formed between the lines 29, and then it is displaced to the bottom of the jam injection structure in the loop, and after the jam is injected into the depression 30 on the top surface of the pastry, it is demoulded and sent to the subsequent processing steps, and then the Chinese, Japanese and Western combined pastries with jam on the top surface are produced in batches, which has high production efficiency and can also meet the requirements that the produced pastries have the advantages of Chinese, Japanese and Western styles at the same time, and not only have the beautiful appearance like Japanese wagashi, but also have the delicious fillings like Chinese moon cakes, and at the same time, the jam with added dough flavor can be formed on the top surface of the pastry in the way of combining Western jam biscuits, so that the final pastry has rich taste and flavor.

[0085] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
