Cartoon confectionery full automatic forming machine

Abstract

The application discloses a full-automatic cartoon confectionery forming machine, aiming at solving the problems of production process interruption, low efficiency and high health risk caused by manual recovery of leftover dough in the production of existing cartoon confectionery. The whole continuous confectionery feeding belt reduces the lodging of confectionery, and the independent cylinder controlled skin cutter realizes accurate cutting and flexible adjustment. The confectionery / skin double conveying line cooperates with the lifting mold driven by the hollow rotating platform to complete the integration of cutting and transfer, and the spraying mechanism enhances the bonding effect. At the same time, the leftover dough automatic recovery mechanism uses the vertical lifting belt and the horizontal conveying belt to efficiently recover the leftover dough. The three-roller dough crushing device prevents clogging and outputs continuous dough belt. Then, the dough is pressed and formed by the dough pressing mechanism and directly returned to the skin line, forming a full closed-loop production. The whole process automation of leftover dough regeneration not only reduces production interruption and manual intervention, but also guarantees food hygiene and safety, and significantly improves the utilization rate of raw materials and the efficiency of continuous operation of the equipment.

Description

Technical Field

[0001] This application relates to the field of food processing equipment, specifically to a fully automatic cartoon-style pastry forming machine. Background Technology

[0002] In the traditional cartoon-themed pastry production field, extensive manual labor is typically relied upon for steps such as dough cutting, pattern creation, transfer and pasting, and subsequent steaming and decoration. This method is not only inefficient and labor-intensive, but also results in poor product consistency, making it difficult to meet the demands of large-scale production. To improve efficiency, existing pastry production utilizes automated equipment, but this equipment can only automatically press dough, cut basic shapes, or perform simple surface treatments. Furthermore, when dealing with the creation and transfer of complex cartoon patterns, it cannot efficiently and hygienically recycle and reuse the "leftover dough" (i.e., scraps after dough cutting) that inevitably arises during the production process. This usually requires tedious manual cleaning and collection, followed by re-mixing and pressing, a process that not only interrupts continuous production, reduces efficiency, increases labor costs, but also poses hygiene risks of material waste and secondary contamination.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

The mounting panel is provided with a control module for controlling the pastry conveying mechanism, the dough conveying mechanism, the dough cutting and transfer mechanism, the spraying mechanism, and the excess dough automatic recycling mechanism.

[0008] In some embodiments of this disclosure, the dough cutting and transfer mechanism includes a housing, a hollow rotating platform disposed within the housing, and a liftable mold unit disposed at the bottom of the hollow rotating platform. The liftable mold unit is used to cut dough from the dough conveying mechanism to create cartoon patterns.

[0012] In some embodiments of this disclosure, the three-roller dough-pounding device includes a main frame, three dough rollers disposed within the main frame, and a dough-pounding mechanism, wherein the dough-pounding mechanism is used to pound excess dough to produce dough strips through the three dough rollers.

[0013] In some embodiments of this disclosure, the dough-pounding mechanism includes a main drive unit and a linkage unit. The main drive unit includes a crank-connecting rod mechanism consisting of a crank and a connecting rod driven by a motor. The linkage unit includes a linkage mechanism consisting of an input connecting rod, an output connecting rod, and a connecting rod. One end of the output connecting rod and the input connecting rod are hinged to the main frame, and the other end is respectively hinged to both ends of the connecting rod. The input connecting rod of the linkage unit is hinged to the end of the connecting rod of the main drive unit, so that the connecting rod in the main drive unit drives the input connecting rod of the linkage unit to swing back and forth, and the output connecting rod of the linkage unit swings synchronously under the drive of the input connecting rod.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "connection" and "linkage" in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0023] Unless otherwise specified, the unit modules, components, structures, mechanisms, or sensors involved in the following embodiments are all commercially available products.

[0024] To address the low production efficiency and high hygiene risks associated with the manual collection of scrap dough in existing cartoon-themed pastry production, this application proposes a fully automated cartoon-themed pastry forming machine. Figure 1 As shown, the machine includes a frame. Specifically, in this embodiment, the frame includes a frame 1 and a mounting panel 2 erected on the frame 1. The frame 1 and mounting panel 2 serve as the supporting foundation for various functional modules, realizing an integrated machine for automatic production of cartoon pastries. To facilitate the conveying of pastries and dough sheets, a pastry conveying mechanism and a dough sheet conveying mechanism 3 are arranged side by side on the frame 1. To ensure synchronous conveying of the pastry conveyor belt and the dough sheet conveyor belt for convenient production of cartoon pastries, a synchronously rotating servo motor is provided on the back of the frame 1 for driving. Above the pastry conveying mechanism and the dough sheet conveying mechanism 3, a dough sheet cutting and transfer mechanism 9 is provided for cutting dough sheets to produce cartoon pastries, simultaneously realizing the cutting of cartoon dough sheets and the pasting of cartoon pastries, reducing operation steps and improving production efficiency. To address the issue of leftover dough scraps, an automatic leftover dough scrap collection mechanism is installed at the end of the dough sheet conveying mechanism 3. Furthermore, to minimize resource waste, this automatic collection mechanism includes not only a leftover dough scrap collection conveyor belt for automatically receiving and transporting leftover dough from the dough sheet conveying mechanism 3, but also a three-roller dough-pressing device 14 whose inlet connects to the outlet of the leftover dough scrap collection conveyor belt and presses the collected leftover dough into a continuous dough strip. Additionally, a dough-pressing mechanism is located downstream of the three-roller dough-pressing device 14 to thin and shape the dough strip output from the three-roller dough-pressing device 14 and re-transport it to the dough sheet conveying mechanism 3. Through the leftover dough scrap collection conveyor belt, the three-roller dough-pressing device 14, and the dough-pressing mechanism, used leftover dough scraps are collected and pressed into dough sheets, forming a closed-loop production process and reducing resource waste.

[0025] Specifically, the entire machine is operated in coordination by the PLC control module 27 located on the mounting panel 2. The control module 27 also includes an electronic screen, which controls and monitors the operation of the pastry conveying mechanism, the dough conveyor 3, the dough cutting and transfer mechanism, the spraying mechanism, and the automatic dough recycling mechanism.

[0026] Furthermore, such as Figure 1 As shown, the dough conveying mechanism 3 is a dough conveyor belt, and the pastry conveying mechanism includes a pastry feeding belt 4, a pastry spraying belt 5, and a pastry decoration belt 8. To ensure synchronous conveying of the dough conveying mechanism 3 and the pastry conveying mechanism, a servo motor is provided on the back of the frame 1 corresponding to the aforementioned conveyor belt for synchronous rotation and driving the conveying. To achieve pastry spraying and ensure the stability of pastries in the next process of applying dough decoration, a spray head 6 connected to an external water source is provided above the pastry spraying belt 5, and a water collection tray 7 for collecting excess water is provided below the pastry spraying belt 5. In particular, the pastry feeding belt 4 is a continuous conveyor belt to reduce the collapse of pastries during feeding.

[0027] Furthermore, such as Figure 2 As shown, the dough cutting and transfer mechanism includes an independently set housing 10, a hollow rotating platform 11 fixed inside the housing 10, and a liftable mold unit set at the bottom of the hollow rotating platform 11. To cut dough from the dough conveying mechanism 3 to create cartoon patterns and to produce cartoon pastries on the pastry conveying mechanism, two liftable mold units are provided, each positioned above the pastry conveying mechanism and the other above the conveying mechanism, allowing the hollow rotating platform 11 to move the liftable mold units on the dough conveying mechanism 3 and the pastry conveying mechanism. Each liftable mold unit includes several independent dough-picking cutters 12. Considering that some individual dough-picking cutters 12 may wear out and fail to cut the dough, each cutter is connected to the hollow rotating platform 11 via a corresponding telescopic cylinder 13 for easy adjustment without affecting the overall process.

[0028] Furthermore, such as Figure 1 As shown, due to the overall layout of the various mechanisms, the excess dough conveyor belt includes a vertical lifting belt 15 and a horizontal conveyor belt 16. The beginning of the horizontal conveyor belt 16 connects to the vertical lifting belt 15, and the end connects to the three-roller dough compaction device 14. The horizontal conveyor belt 16 is used to receive the excess dough from the vertical lifting belt 15 and transport it to the three-roller dough compaction device 14, serving as an intermediate support. The vertical lifting belt 15 includes two parallel conveyor belts that move vertically, with a certain distance between them to jointly clamp the excess dough on the dough conveying mechanism 3. Preferably, a servo motor is provided on the mounting panel 2 corresponding to the two conveyor belts for synchronous rotation, so that the synchronous rotation of the two conveyor belts can jointly clamp the excess dough.

[0029] Furthermore, such as Figure 3As shown, the three-roller dough-pounding device 14 includes a main frame 28, three dough rollers 29 disposed within the main frame 28, and a dough-pounding mechanism. Preferably, the main frame 28 is a device housing fixed to the mounting panel 2. The dough-pounding mechanism for pounding the remaining dough and the three dough rollers 29 for rolling the dough into a dough strip are both installed inside the device housing. To achieve the pounding of the remaining dough, the dough-pounding mechanism includes a main drive unit and a linkage unit. The linkage unit includes a linkage mechanism composed of an input connecting rod 20, an output connecting rod 21, and a connecting rod 22. One end of the output connecting rod 21 and the input connecting rod 20 are hinged to the main frame, and the other end is respectively hinged to both ends of the connecting rod 22. The output connecting rod 21 can swing synchronously under the swing of the input connecting rod 20. The main drive unit includes a crank-connecting rod mechanism consisting of a crank 18 driven by a motor 17 and a connecting rod 19. Preferably, the motor 17 is located on the back of the mounting panel 2, and its rotating shaft is connected to the crank 18. The input connecting rod 20 of the linkage unit is hinged to the end of the connecting rod 19 of the main drive unit, so that the connecting rod 19 drives the input connecting rod 20 of the linkage unit to swing back and forth, and the output connecting rod 21 of the linkage unit swings synchronously in accordance with the parallelogram principle under the drive of the input connecting rod 20. In this embodiment, the crank-connecting rod mechanism is used as the drive unit to drive the linkage mechanism to swing. At the same time, in order to facilitate tamping, the input connecting rod 20 and the output connecting rod 21 are provided with tamping panels 23 that are bent in the direction of the three-roller 29, so that the tamping panels 23 are driven to tamp the remaining surface under the swing of the linkage mechanism of the linkage unit in accordance with the parallelogram principle. Specifically, the three dough rollers 29 are set below the pounding panel. The remaining dough is pounded into dough by the pounding panel 23 and then pressed into dough strips by the three dough rollers 29. Finally, the dough strips are output to the pressing mechanism through the dough outlet of the main frame 28.

[0030] Furthermore, to achieve the thinning and shaping of the dough strip, the dough pressing mechanism includes several pressing rollers 24 arranged in a linear array, a dough pressing conveyor belt 25 disposed between the pressing rollers 24, and a power roller 26 disposed above the dough pressing conveyor belt 25. The power roller 26 rotates at the same speed as the dough pressing conveyor belt 25 to drive the dough strip to move on the dough pressing conveyor belt 25 and prevent the dough strip from sagging. Specifically, the pressing rollers 24, the dough pressing conveyor belt 25, and the power roller 26 are all mounted on the mounting panel 2, and their power sources are all from servo motors on the back of the mounting panel 2, enabling the pressing rollers 24, the dough pressing conveyor belt 25, and the power roller 26 to thin and shape the dough strip and convey it to the beginning of the dough sheet conveying mechanism 3. Preferably, the outlet of the three-roller dough-pressing device is equipped with a pressing roller to initially thin the dough strip. The pressing roller 24 is connected to the inlet of the pressing conveyor belt 25, so that the dough strip is transported upward at an incline under the combined action of the power roller 26 and the pressing conveyor belt 25. The end of the pressing conveyor belt 25 is connected to two sets of pressing rollers 24 in sequence for further thinning. This process ensures that the dough strip is thinned evenly. Preferably, the pressing mechanism is equipped with a photoelectric sensing component connected to the control module 27, which can control the start and stop of each component to prevent the dough strip from stacking.
