Description

Technical Field

[0001] This utility model relates to the field of food machinery technology, specifically to an automatic separation device for continuous slicing of fresh dough sheets. Background Technology

[0002] Background Technology In the field of pasta product processing, the stamping and forming of fresh dough sheets (such as dumpling wrappers) is one of the key processes to ensure production efficiency and product quality. Currently, the processing of fresh dough sheets in the industry is mostly completed manually or with semi-automatic equipment: first, a stamping machine is used to stamp large sheets of dough into finished dough sheets of a specific shape, and then manual labor is used to separate the finished dough sheets from the surrounding mesh residue and collect them separately.

[0003] This traditional processing method has obvious drawbacks: First, manual separation is slow and cannot match the production rhythm of high-speed stamping equipment, becoming a bottleneck restricting capacity improvement; second, direct human contact with the product greatly increases the risk of food contamination, failing to meet modern food processing hygiene standards; third, fresh dough is soft and easily sticks together, making it difficult to control the force during manual separation, which can easily lead to dough deformation or damage, reducing the product yield; fourth, the production process relies heavily on manual labor, which not only increases labor costs but also increases the management difficulty for enterprises.

[0004] Therefore, the industry urgently needs a fully automated device that can continuously press, automatically separate, and classify fresh dough sheets to solve many problems of the traditional processing methods and meet the needs of industrial production. Utility Model Content

[0005] The purpose of this utility model is to address this issue by proposing an automatic separation device for continuous sheeting of fresh dough. This device requires no manual intervention, effectively improving production efficiency and food hygiene and safety, preventing damage to finished products, and is suitable for the industrial production of dumpling wrappers and other pasta products.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an automatic separation device for continuous punching of fresh dough sheets, comprising a punching conveyor, a punching mechanism, a separation mechanism, a finished product turning conveyor, and a waste material conveyor, wherein the components are arranged in sequence along the material conveying direction, wherein: The press conveyor is used to horizontally carry and transport large, multi-layered, folded raw fresh noodle sheets, and adopts an intermittent feeding method of "movement-stop-movement". The stamping mechanism is mounted across the top of the stamping conveyor and is used to continuously stamp the raw fresh dough sheet below when the stamping conveyor stops, forming a composite dough belt with finished dough sheet and mesh residue. The separation mechanism is located behind the stamping mechanism and is used to forcibly separate the finished surface skin from the mesh residue in the composite surface belt; The finished product turning conveyor is located on the finished product output side of the separation mechanism and is used to receive the separated finished product skins and change their conveying direction. The waste material conveyor is located on the waste material output side of the separation mechanism and above the finished product turning conveyor, and is used to receive and convey the separated mesh waste material.

[0007] To further optimize this utility model, the following technical solutions may be preferred: Preferably, it also includes an electronic control system, which coordinates and controls the timing of the actions of each component.

[0008] Preferably, the stamping conveyor is a flat belt conveyor, and its conveyor belt is a food-grade smooth polyurethane belt or a Teflon belt.

[0009] Preferably, the stamping mechanism includes a stamping drive cylinder mounted on the frame and a stamping die connected to the stamping drive cylinder. The stamping die is provided with a plurality of circular or irregularly shaped punches arranged in an array, and each punch has an elastic ejector device in the die. The elastic ejector device includes an ejector plate and an elastic element, and the ejector plate is connected to the stamping plate through the elastic element.

[0010] Preferably, the separation mechanism includes a finished product lifting mechanism, a finished product conveyor belt, a cylinder, and a mesh residual material support rod. The finished product conveyor belt receives the finished product skin and conveys it downward through lifting motion, while the mesh residual material moves forward under its own conveying power, thereby achieving separation from the finished product skin.

[0011] Preferably, the finished product turning conveyor is an annular food-grade synchronous belt with a synchronous pulley on its inner side for driving operation, and the conveying direction is at a 90-degree angle to the conveying direction of the stamping conveyor.

[0012] Preferably, the waste material conveyor is a flat belt conveyor or a mesh belt conveyor, and its conveying direction is consistent with the original conveying direction of the stamping conveyor.

[0013] Preferably, it also includes a visual positioning system, which is installed on the frame and located above the stamping conveyor, for identifying the position of the original fresh dough sheet and feeding back a signal to the electronic control system to adjust the feed distance of the stamping conveyor.

[0014] Preferably, the stamping die of the stamping mechanism is adapted to the stamping requirements of dumpling skin, and its punch has a circular structure.

[0015] Preferably, the separating mechanism operates synchronously with the stamping mechanism. Each time a stamping is completed, the separating mechanism rises and falls once to transfer the finished dough.

[0016] This utility model has the following beneficial effects: (1) Full-process automation and high efficiency: This device achieves full automation of fresh dough sheets from intermittent conveying and continuous stamping to the separation and classified conveying of finished products and leftover materials through the coordinated operation of core components such as the stamping conveyor and stamping mechanism along the material direction, combined with the precise coordination of the timing of each component by the electrical control system and the dynamic adjustment of the feeding distance by the vision positioning system, without the need for manual intervention. It not only solves the bottleneck problems of slow separation speed and inability to match high-speed stamping in traditional manual methods, but also greatly improves production efficiency, reduces the risk of food contamination caused by human contact, reduces labor costs and management difficulty, and meets modern food processing hygiene standards.

[0017] (2) Product precision and integrity assurance: The intermittent feeding of the stamping conveyor with "movement-stop-movement" combined with the precise stamping when the stamping mechanism stops, and the position calibration of the visual positioning system, ensures accurate punching position; the array punches of the stamping die and the elastic ejector device (ejector plate + elastic element) in the die can prevent the dough from sticking to the die; the synchronous lifting action of the separation mechanism and the stamping mechanism, and the flexible support of the finished product conveyor belt, effectively solve the problem of the soft and fragile fresh dough, ensure the consistency of the shape and size of the finished product, reduce the deformation and breakage rate, and improve the stability of product quality.

[0018] (3) Thoroughness of separation and rationality of layout: The separation mechanism achieves forced separation of finished products and waste materials through the reverse movement of finished product lifting and conveying and mesh waste material forward conveying; the design of finished product turning conveyor (90-degree circular synchronous belt) and waste material conveyor (up and down layout, same conveying direction) ensures that the two are separated in space and thoroughly separated, while greatly reducing the equipment footprint, optimizing the workshop logistics path, and adapting to the site requirements of large-scale production.

[0021] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1: This embodiment takes a fresh dough skin continuous punching and automatic separation device adapted to dumpling skin processing as an example. Its structure and working principle can be extended to the processing scenarios of other shapes of fresh dough skin 6.

[0024] I. Overall Composition of the Device The automatic separation device for continuous punching of fresh dough sheets in this embodiment consists of a punching conveyor 1, a punching mechanism 2, a separation mechanism 3, a finished product turning conveyor 4, and a waste material conveyor 5 arranged sequentially along the material conveying direction, and is equipped with an electrical control system and a vision positioning system 7. The waste material conveyor 5 is located above the finished product turning conveyor, forming a "top-bottom split" spatial layout. The electrical control system coordinates the action sequence of all components, and the vision positioning system ensures the punching accuracy. All components together constitute a fully automated processing flow.

[0025] II. Specific Structure and Function of Each Component (a) Stamping Conveyor 1 The stamping conveyor 1 uses a flat belt conveyor with a food-grade smooth polyurethane belt (or Teflon belt) – this material combines wear resistance and non-stick properties, preventing the conveyor belt from sticking during the transport of multi-layered dough sheets, and meeting food hygiene standards. The conveyor employs an intermittent "motion-stop-motion" feeding method: when the conveyor reaches the designated stamping position, the electrical control system stops the conveyor; after the stamping mechanism completes one stamping cycle, the conveyor advances a rated distance (the feed distance can be dynamically adjusted via a vision positioning system), ensuring that the dough sheet area is not overlapped or missed in each stamping. The vision positioning system 7 is installed above the frame and in front of the stamping mechanism. It uses image recognition technology to capture the edges and positions of large, multi-layered, folded fresh dough sheets, feeding the signal back to the electrical control system in real time; if the dough sheet position deviates, the electrical control system immediately adjusts the conveyor's feed distance to ensure that the stamping die is precisely aligned with the area to be processed.

[0026] (ii) Stamping mechanism 2 The stamping mechanism is mounted across the top of the stamping conveyor and fixed on the frame. It mainly consists of a stamping drive cylinder 201, a stamping die 202 and an elastic ejector device 203: (1) The stamping drive cylinder is a double-acting cylinder. Its piston rod is rigidly connected to the stamping die, which can drive the die to press down and return quickly. The pressing speed and force are adjusted by the electronic control system to meet the punching requirements of fresh dough (usually 1-2mm thick) and avoid excessive force that could damage the dough; (2) The die base of the stamping die has circular punches 204 arranged in an array (e.g., 1 row × 10 columns). The diameter of the punches is suitable for dumpling skin specifications (usually 60-80mm). If other shapes of dough are to be processed, punches with irregular shapes can be replaced. The mold; a pressure plate 206 is designed on the lower part of the circular punch on the stamping mold to prevent the dough from sticking. (3) Each punch has an elastic ejector device in the die: the ejector plate 205 is a circular steel plate (the diameter is slightly smaller than the inner diameter of the punch), which is connected to the stamping plate by 2-4 springs (elastic elements). As a replacement technical solution, a gravity plate is used instead of the ejector plate in this embodiment. During stamping, the ejector plate first contacts the dough and compresses the spring. After the die completes the punching, the spring is reset during the return stroke (relying on the weight of the gravity plate). The ejector plate will slightly push out the dumpling skin that may stick to the punch, so as to prevent the dough from detaching from the composite dough belt with the return stroke of the mold, and prepare for the subsequent separation mechanism to pick it up.

[0027] (III) Separation Mechanism The separation mechanism is located behind the stamping mechanism and moves synchronously with the stamping mechanism. It mainly consists of a finished product lifting mechanism 301, a finished product conveyor belt 302, a drive cylinder 303, and a mesh scrap support rod 305: (1) The finished product lifting mechanism is driven by a small servo motor, which can drive the finished product conveyor belt to make a "lifting" motion (lifting stroke 300-500mm). After each stamping is completed, the lifting mechanism lifts and lowers synchronously once. After the stamping is completed, the composite surface belt (including dumpling skin and mesh scrap) is transported to the separation mechanism. The lifting mechanism drives the finished product conveyor belt to rise, so that the finished product conveyor belt fits the bottom surface of the dumpling skin; (2) The finished product conveyor belt is a narrow food-grade belt (the width is slightly smaller than the diameter of the dumpling skin). After rising, it supports the bottom surface of the dumpling skin. The dumpling skin is received and conveyed downwards (the conveying direction is perpendicular to the stamping conveyor). At the same time, the top of the finished product conveyor is also designed with a pressure plate 304. Multiple pressure plates are designed corresponding to the dumpling skin positions. The pressure plate is connected to a drive cylinder to transfer the dumpling skin to the finished product turning conveyor. (3) The mesh residual material support rod is 3-4 parallel metal rods (80-100mm apart), located on both sides of the finished product conveyor belt. Its height is flush with the conveying plane of the composite surface belt. When the finished product conveyor belt conveys the dumpling skin downwards, the mesh residual material has a certain rigidity. Under the traction power of the residual material conveyor, it moves forward along the support rod and achieves "upper and lower separation" from the dumpling skin, avoiding the residual material pulling the dumpling skin and causing deformation during the separation process.

[0028] (iv) Finished product turning conveyor The finished product turning conveyor uses a ring-shaped food-grade synchronous belt with two synchronous pulleys meshing on its inner side (the drive pulley is driven by a stepper motor). The conveying direction of the synchronous belt is at a 90-degree angle to the conveying direction of the stamping conveyor, achieving "lateral transfer". When the finished product conveyor belt of the separation mechanism transports dumpling wrappers onto the synchronous belt, the synchronous belt operates at a uniform speed (matching the speed of the finished product conveyor belt, usually 0.5-1m / s), smoothly conveying the dumpling wrappers to the next process (such as a dumpling wrapping machine or a plating machine). The surface of the synchronous belt is treated with a slightly raised texture to enhance the friction with the dumpling wrappers and prevent slippage during transport.

[0029] (v) Waste material conveyor The waste material conveyor uses a flat belt conveyor (or a mesh belt conveyor; mesh belts are suitable for applications requiring rapid heat dissipation). Its conveying direction is consistent with the original conveying direction of the stamping conveyor, and the conveyor body is mounted above the finished product turning conveyor (height difference 300-500mm), without occupying additional ground space. The separated mesh waste material (thickness consistent with the original dough, in a mesh shape) is received by the waste material conveyor and conveyed at a uniform speed to the waste material collection box (or return device) at the end. If a return device is included, the waste material can be crushed and re-mixed, achieving raw material recycling and reducing production costs.

[0030] (vi) Electrical control system The electrical control system is based on a PLC (Programmable Logic Controller) and is equipped with a touch screen (for parameter setting and status display). Its input end is connected to the vision positioning system and the position sensors of each component (such as the limit switch of the conveyor and the travel switch of the stamping mechanism). Its output end is connected to the solenoid valves of each drive motor and cylinder. Through the preset program, the electrical control system realizes the following coordinated control: (1) The stamping conveyor stops → vision positioning calibration → the stamping mechanism presses down to punch → elastic ejection → the stamping mechanism returns → the stamping conveyor feeds; (2) the stamping mechanism punches and cuts → the separation mechanism lifts and receives the finished product → the finished product conveyor belt conveys → the finished product turning conveyor receives the material; (3) the feeding action of the residual material conveyor and the stamping conveyor is synchronized to ensure that the residual material is pulled and separated in time.

[0031] III. Device Working Process ① Feeding and conveying: Place the large, multi-layered, folded fresh dough sheets (usually 10-50 layers, total thickness 10-100mm) that have been powdered on both sides (to prevent sticking between layers) at the feeding end of the stamping conveyor. The electrical control system starts the conveyor and feeds the dough sheets to the stamping mechanism intermittently. ② Precision stamping: When the dough reaches the stamping position, the conveyor stops. After the vision positioning system confirms the position of the dough, the stamping drive cylinder drives the mold to press down. The punch array punches out multiple layers of dumpling skins in one go, forming a composite dough belt of "dumpling skin + mesh residue". During the return stroke, the elastic ejector pushes out the dumpling skins that are stuck to the punch. ③ Separation and conveying: The composite material is conveyed to the separation mechanism by the belt conveyor, and the finished product lifting mechanism drives the finished product conveyor belt to rise to receive the dumpling skins and convey them downward to the finished product turning conveyor; the mesh waste material moves forward under the traction of the waste material conveyor, and after separating from the dumpling skins, it enters the waste material collection box. ④ Finished product output: The finished product turning conveyor turns and transports the dumpling wrappers to the next process, completing one processing cycle.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
