Description

Technical Field

[0001] The utility model relates to the technical field of physical processing of food, in particular to a food die-cutting decal assembly. Background Art

[0002] As a popular traditional food, the production process of glutinous rice balls and similar foods is gradually shifting from manual production to automated production. Automated production lines can not only improve production efficiency, but also ensure the consistency of product quality. In automated production lines, the skin cutting and decaling process is a key step in improving product appearance and market competitiveness.

[0003] Taking glutinous rice balls as an example, the current production lines for cutting and decaling on the market mainly use mechanical push rods to achieve precise placement of decorative pieces. This technology performs well when processing a single large decorative piece, but when it comes to small decorative pieces, especially multiple small decorative pieces, its limitations and defects become particularly obvious: ① Increased structural complexity: If the existing technology is used to cut and decal multiple small decorative pieces, it is necessary to increase the number of corresponding push rods and drive mechanisms, resulting in a complex structure and increasing the difficulty of design, manufacturing and maintenance. ② Insufficient stability and reliability: For example, when making patterns with rich details and small decorative pieces, such as the mouth features of a panda, the existing technology cannot produce a push rod that is small enough to complete this process. Even if a sufficiently small push rod is produced, the push rod will not be able to achieve the bonding processing of multiple small decorative pieces due to insufficient strength. ③Deformation of the food being pasted and poor adhesion of the decorative sheet: In the process of pasting the decorative sheet on the glutinous rice balls, the push rod will exert a certain pressure on the glutinous rice balls, which may cause the glutinous rice balls to deform. In addition, the push rod only acts on a part of the decorative sheet, and its edge cannot be tightly combined with the glutinous rice balls. In order to solve this problem, it is usually necessary to use a glutinous rice ball shaping device to press the edge of the decorative sheet again, which undoubtedly increases the process steps and reduces production efficiency. Utility Model Content

[0004] In order to overcome the above three technical problems or one of the three technical problems in the prior art, the utility model provides a food die-cutting decal assembly.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A food die-cutting decal assembly comprises, from top to bottom, a fixed plate, a movable plate and a lower template, wherein the fixed plate and the lower template are fixedly connected by at least two axially vertical guide rods, each of the guide rods is slidably fitted with a guide sleeve, the movable plate is fixedly connected to all the guide sleeves, a cylinder with a stroke in the up and down directions is fixedly arranged on the fixed plate, the piston rod of the cylinder passes through the fixed plate and is connected to the movable plate, and the dough is intermittently displaced on the upper surface of the lower template, which is different from the prior art in that an upper template is fixedly connected below the movable plate, and a linear array of embedding grooves of more than two rows and more than two columns in each row is arranged on the lower surface of the upper template, each of which has a plurality of grooves. Each of the embedding groove groups includes more than two embedding grooves with closed cross-sections and the same or different shapes; a groove is provided on the upper surface of the upper template at a position corresponding to each of the embedding groove groups as a static pressure chamber, and a branch airway passing through the groove is provided on the bottom of each of the embedding grooves; an annular groove is provided on the outer side of the groove, and an O-ring is embedded in the annular groove; a main airway is provided on the movable plate at a position corresponding to each of the embedding grooves; a die-cutting rod with a cross-sectional shape consistent with the contour of the embedding groove is interference-inserted in each of the embedding grooves, and an air hole passing through the upper and lower parts is provided in the die-cutting rod; a die-cutting hole that cooperates with each of the die-cutting rods for die-cutting is provided on the lower template.

[0007] Furthermore, a baffle plate is fixedly connected to the top of the lower template with a distance therefrom, and a through hole is provided on the baffle plate to match the clearance of each of the die-cutting rods.

[0008] Furthermore, a quick-connect joint is installed on the movable plate corresponding to the upper end of each of the main air channels, and a pneumatic distribution valve is connected to each of the quick-connect joints through a pipeline, and the pneumatic distribution valve is connected to the high-pressure air circuit.

[0009] Furthermore, the pneumatic dispensing valve is configured to automatically open when the lower end of the die-cutting rod approaches or slightly presses the food to be attached, so that air flows out from each of the air holes to apply the die-cut decal to the food to be attached.

[0010] Furthermore, a spring is sleeved on the guide rod below the guide sleeve.

[0011] Furthermore, the guide sleeve is replaced by a linear bearing.

[0012] Furthermore, the middle portion of the lower end of the die cutting rod is recessed upward so that a cutting edge is formed on the edge.

[0013] Furthermore, when the die-cutting rod passes over the die-cutting hole and moves downward to the limit position, the lower end of the die-cutting rod approaches or slightly presses the food to be stuck.

[0014] Compared with the prior art, the food die-cutting decal assembly of the utility model has the following beneficial effects:

[0015] 1. By adopting modular design and simplified pneumatic control, the number and complexity of components required are reduced, making the structure of the entire assembly simpler and reducing the difficulty of design, manufacturing and maintenance.

[0016] 2. Abandoning the top rod avoids failures caused by insufficient strength and improves the stability and reliability of the equipment.

[0017] 3. The wind pressure is used to achieve gentle pressing of the decorative sheet, avoiding deformation of the food being stuck during the die-cutting process, while ensuring that the decorative sheet and the food being stuck are stuck more closely and evenly.

[0018] 4. Interference fitting can achieve high-precision fit by accurately inserting the die-cut rod into the groove, ensuring that the size and shape of the connected part meet the design requirements. It avoids the deformation and error that may be caused by traditional connection methods such as welding, ensuring the precise fit and consistency of the components. Compared with connection methods such as welding that require specific equipment and materials, interference fitting can simplify the manufacturing process and reduce production costs. When components with interference fitting need to be replaced or maintained, they are usually easier to disassemble, reducing maintenance time and workload.

[0019] 5. The component design is suitable for automated production lines, which helps to achieve a higher degree of automation. The number and layout of die-cutting bars can be adjusted according to the needs of different foods, which improves the adaptability and flexibility of the components.

[0020] In summary, the food die-cutting decal assembly of the utility model solves the limitations of the prior art through innovative design and provides users with a more efficient, reliable and economical solution. BRIEF DESCRIPTION OF THE DRAWINGS

A quick-connect connector 8 is installed on the upper end of each of the main airways 21 on the movable plate 2, and a pneumatic distribution valve is connected to each of the quick-connect connectors 8 through a pipeline, and the pneumatic distribution valve is connected to the high-pressure air circuit.

[0036] In this embodiment, the food 100 to be labeled is glutinous rice balls as an example, and the working process of the die-cutting decal assembly can be summarized into the following steps:

[0037] 1. Fixing and guiding: The fixing plate 1 and the lower template 3 form the fixing foundation of the assembly, and are fixed by the axial vertical guide rod 4 to provide stable support for the assembly.

[0038] 2. Drive and displacement: The cylinder 6 is used as a drive mechanism to drive the movable plate 2 to move up and down. The movable plate 2 slides with the guide rod 4 through the guide sleeve 5 to achieve precise control.

[0039] 3. Die-cutting preparation: The upper template 7 is fixedly connected to the bottom of the movable plate 2, and its lower surface is arrayed with embedding groove groups 71, each embedding groove group 71 includes a plurality of embedding grooves 711, which are designed for die-cutting the dough.

[0040] 4. Air circuit: The sink 72 is provided corresponding to each embedding groove group 71 and is connected to the branch airway 712 to form a pneumatic control circuit. The main airway 21 is opened on the movable plate 2 and communicated with the sink 72.

[0041] 5. Die-cutting and applique action: The die-cutting rod 9 is inserted into the embedding groove 711 with an air hole 91. When the movable plate 2 moves downward, the die-cutting rod 9 cooperates with the die-cutting hole 31 to die-cut the dough into an applique.

[0042] 6. Airflow-assisted lamination: When the movable plate 2 continues to move downward, the die-cutting rod 9 approaches or slightly presses against the glutinous rice balls, triggering the pneumatic distribution valve to open, and airflow is ejected through the air holes 91 to laminarize the die-cut dough decals onto the glutinous rice balls.

[0043] 7. Periodic production: The die-cutting rod 9 retracts to prepare for the next die-cutting action. The dough moves intermittently on the lower mold plate 3 to ensure a continuous supply of new dough.

[0044] The entire assembly is designed to automate the die-cutting and decaling process, improving production efficiency and product quality through the collaborative work of mechanics and pneumatics.

[0045] In another preferred embodiment, a baffle 10 is fixedly connected to the upper part of the lower template 3 with a spacing therefrom, and a through hole 101 is provided on the baffle 10 to be gap-matched with each of the die-cutting rods 9, and the baffle 10 is suitable for preventing the dough skin from moving upward with the die-cutting rods 9. The existence of the baffle 10 effectively prevents the dough skin from moving upward with the die-cutting rods 9 during the die-cutting process, thereby avoiding displacement and deformation of the dough skin due to the die-cutting action, thereby improving production efficiency.

[0046] In another preferred embodiment, a quick-connect joint 8 is installed on the movable plate 2 corresponding to the upper end of each of the main air channels 21, and a pneumatic distribution valve is connected to each of the quick-connect joints 8 through a pipeline, and the pneumatic distribution valve is connected to the high-pressure air circuit. Through the centralized control of the pneumatic distribution valve, the airflow of each main air channel 21 can be accurately managed to ensure the synchronization and consistency of the pneumatic action of the die-cutting rod 9. The pneumatic distribution valve can adjust the pressure to ensure that each die-cutting rod 9 obtains the appropriate air pressure, thereby controlling the strength and speed of the die-cutting action and improving the die-cutting accuracy.

[0047] In another preferred embodiment, a spring 11 is sleeved on the guide rod 4 below the guide sleeve 5. The spring 11 can absorb the impact force generated when the movable plate 2 is quickly moved into position, reducing the impact damage to the guide rod 4 and the guide sleeve 5. The spring 11 can ensure that the movable plate 2 can return to a certain position at the beginning and end of each stroke, thereby improving the positioning accuracy. The spring 11 can provide a certain preload force for the guide rod 4, thereby reducing the vibration and deviation of the guide rod during movement. Reduce the inaccurate punching caused by mechanical vibration and improve the consistency and quality of the product.

[0048] In another preferred embodiment, the guide sleeve 5 is replaced by a linear bearing. The linear bearing can provide a lower friction interface than the traditional guide sleeve, thereby reducing the energy consumption required to drive the cylinder and improving the overall efficiency. The linear bearing can ensure a smoother and more stable movement of the movable plate 2 on the guide rod, which helps to improve the punching accuracy. Due to the lower friction, the wear rate of the linear bearing and the guide rod will be reduced, thereby extending the service life of the components. The linear bearing can provide precise guidance, making the position of the movable plate 2 more accurate and ensuring the accuracy of the punching position.

[0049] In another preferred embodiment, the middle portion of the lower end of the die-cutting rod 9 is recessed upward so that the edge forms a cutting edge 92, and the recess is suitable for the dough to be die-cut to be embedded without falling off. The design of the cutting edge 92 can ensure that the die-cutting rod 9 fits the dough more accurately, achieving a clean and neat die-cutting action. The recessed design allows the dough to be die-cut to be embedded in the cutting edge 92 during punching, reducing the dough from floating or shifting due to the punching action. Reducing the floating of dough means reducing the need to adjust and reposition the dough, thereby improving production efficiency.

[0050] In another preferred embodiment, when the die-cutting rod 9 passes over the die-cutting hole 31 and descends to the limit position, the lower end of the die-cutting rod 9 approaches or slightly presses the food 100 to be attached. The pneumatic dispensing valve is configured to automatically open when the lower end of the die-cutting rod 9 approaches or slightly presses the food 100 to be attached, so that airflow is ejected from each of the air holes 91 to apply the die-cut decal to the attached food 100. The lower end of the die-cutting rod 9 is close to or slightly in contact with the attached food 100 to ensure the precise placement of the decal and improve the accuracy of the attachment. The automatic opening of the pneumatic dispensing valve is associated with the position of the die-cutting rod 9, which realizes the automatic control of the attachment process and reduces human intervention. The precise injection of airflow helps to ensure that the die-cut decal is evenly attached to the attached food 100, especially the edges will not be lifted, which improves the overall quality of the product.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
